Banco Santander to acquire Webster Financial (NYSE: WBS) in $12.3B cash-and-stock deal

Rhea-AI Filing Summary

Webster Financial Corporation reports on its diversified banking business and highlights a pending acquisition by Banco Santander. As of December 31, 2025, Webster had $84.1 billion in total consolidated assets and operates three main segments: Commercial Banking, Healthcare Financial Services, and Consumer Banking.

On February 3, 2026, Webster agreed to be acquired by Banco Santander in a two-step merger and share exchange valued at approximately $12.3 billion, based on Banco Santander’s February 2, 2026 closing price. Webster stockholders are expected to receive $48.75 in cash plus 2.0548 ADSs or Ordinary Shares for each Webster share, with closing targeted for the second half of 2026, subject to regulatory and shareholder approvals.

The filing also describes a private credit joint venture with Marathon Asset Management and notes that change-of-control events at both Marathon and Webster could allow the non-affected member to dissolve the venture. Webster details its extensive regulatory environment, capital and liquidity framework, and a formal risk governance structure, along with 4,498 full-time employees and a culture focused on engagement, inclusion, and talent development.

Positive

• Transformative acquisition valuation: Banco Santander has agreed to acquire Webster in a transaction valued at approximately $12.3 billion, with Webster shareholders set to receive a defined package of $48.75 in cash plus 2.0548 ADSs or Ordinary Shares for each share.

Negative

• Execution and approval risks around Banco Santander transaction: Closing depends on regulatory and shareholder approvals and faces detailed risks including potential delays, termination, integration challenges, reputational impacts, and dilution from Banco Santander’s additional Ordinary Shares and ADSs.
• Joint venture uncertainty from dual change-of-control events: The Marathon Asset Management sale and Webster’s own transaction each create a change of control, giving the non-affected member 120 days to dissolve the private credit joint venture and wind down its entities.

Insights

Banking M&A and regulation analyst

Banco Santander’s planned $12.3B acquisition of Webster is a transformative but heavily conditioned event.

The centerpiece is Banco Santander’s agreement to acquire Webster Financial in a stock-and-cash transaction valued at about $12.3 billion, with holders receiving $48.75 in cash plus 2.0548 ADSs or Ordinary Shares per Webster share. This would shift Webster from an independent regional banking group into part of a global institution.

Completion depends on approvals from the Federal Reserve, the European Central Bank, both companies’ stockholders, and other customary conditions. The forward-looking section outlines numerous risks: realization of cost savings and synergies, regulatory or legal proceedings, potential delays or termination of the agreement, reputational impacts, and dilution from Banco Santander’s share issuance.

Separately, Webster’s private credit joint venture with Marathon Asset Management contains change-of-control clauses. The announced sales of Marathon to CVC Capital Partners and Webster to Banco Santander give the non-affected partner a 120-day window after a change in control to elect dissolution, which could trigger a wind-down of the JV entities following closing events.

PART I

ITEM 1. BUSINESS

General

The Company is a bank holding company that has elected to be treated as a financial holding company under the BHC Act, incorporated under the laws of Delaware in 1986, and headquartered in Stamford, Connecticut. As of December 31, 2025, the Company had $84.1 billion in total consolidated assets.

The Bank is a commercial bank with a national bank charter focused on providing financial products and services to businesses, individuals, and families. While its core footprint spans the Northeast from the New York metropolitan area to Rhode Island and Massachusetts, certain businesses operate in extended geographies. The Bank offers three differentiated lines of business: Commercial Banking, Healthcare Financial Services, and Consumer Banking.

Proposed Transaction with Banco Santander

On February 3, 2026, Webster entered into a Transaction Agreement with Banco Santander and Webster Virginia Corporation, a wholly owned subsidiary of Webster incorporated in the State of Virginia. The Transaction Agreement provides that, upon the terms and subject to the conditions set forth therein, Banco Santander will acquire Webster in two steps. First, Webster will merge with and into Webster Virginia Corporation, with Webster Virginia Corporation continuing as the surviving corporation in such merger. Second, immediately following the completion of such merger, Banco Santander will acquire all outstanding shares of Webster Virginia Corporation through a statutory share exchange. Based on Banco Santander’s closing stock price on February 2, 2026, the Transaction has an aggregate value of approximately $12.3 billion.

Under the terms of the Transaction Agreement, holders of Webster common stock will receive $48.75 in cash and 2.0548 ADSs (or Ordinary Shares in certain circumstances) for each share of Webster common stock that they own. The Transaction Agreement contains customary representations and warranties, covenants, and closing conditions. Completion of the Transaction remains subject to approval by the Federal Reserve and the European Central Bank, approval by the stockholders of each company, and other customary closing conditions. The Transaction is expected to close in the second half of 2026.

Joint Venture with Marathon Asset Management

On July 19, 2024, the Company, through its subsidiary, MW Advisor Holding, LLC, entered into an agreement with Marathon Asset Management and formed a private credit joint venture, which is designed to deliver direct lending solutions for sponsor-backed middle market companies across the country. Information regarding joint venture activities that occurred during the year ended December 31, 2025, can be found within Note 2: Business Developments in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

On January 26, 2026, CVC Capital Partners, a private markets investment firm, announced that it has agreed to acquire 100% of Marathon Asset Management, which will result in a change in control of Marathon Asset Management. Separately, Webster’s Transaction with Banco Santander will result in a change of control of Webster. Pursuant to the operating agreement for Webster’s joint venture with Marathon Asset Management, within 120 days after the consummation of a change in control, the non-affected member may elect to dissolve the joint venture, which would result in the wind-down of MW Advisor, LLC and Marathon Direct Lending SLP, LLC.

Human Capital Resources

As a values-driven organization, our colleagues are the cornerstone of our success. As of December 31, 2025, the Company had 4,498 full-time employees and 103 part-time employees. Our employees are primarily located in our core footprint, which spans the Northeast from the New York metropolitan area to Rhode Island and Massachusetts, including our headquarters in Stamford, Connecticut. The average full-time and part-time employee tenure at the Company is approximately 8.9 years.

Culture and Engagement. We recognize the importance of an engaged workforce, and we support the professional development of our colleagues to help them achieve their career goals. Our 2025 colleague engagement survey results reflected our commitment to establishing a culture of trust and safety by encouraging colleagues to share their opinions and actionable ideas for improvement. Webster provides all colleagues with 24 hours of paid time (pro-rated for new hires and part-time colleagues) to volunteer at the organizations of their choice.

Internal Communication. Our internal communications channels are designed to keep colleagues informed, connected, and aligned with company priorities. We publish Webster Weekly, an all-colleague newsletter that provides regular updates on key initiatives, news, and achievements across the organization. Our intranet, the Vault, serves as a centralized hub for corporate messaging, essential resources and department information, ensuring colleagues have easy access to timely and accurate content. In 2025, we hosted 11 Webster Within webinars, a leadership series featuring members of the executive management committee who share insights on important topics and organizational priorities, supporting transparency, engagement, and ongoing colleague education.

Inclusion and Belonging. At Webster, we believe that fostering a culture of inclusion and belonging is integral to our long-term success. We are committed to attracting, developing, and retaining a talented workforce with a broad range of perspectives, knowledge, and experience. We are dedicated to providing equal employment opportunities to all individuals in accordance with applicable laws. We believe this approach enhances engagement, supports retention, increases job satisfaction, and contributes to a more engaged and productive workforce. Our Business Resource Groups, open to all colleagues on a voluntary basis, are strategic partners who support programs and initiatives that advance talent acquisition and leadership development, colleague retention and productivity, market development, and customer attraction and retention. They further align with corporate strategy by leveraging and capitalizing on the benefits of an inclusive well-qualified workforce to drive innovation, strengthen problem-solving, deepen market insight and enhance colleague engagement and satisfaction.

Compensation. Our compensation program is designed to attract, retain, and reward performance and align incentives with achievement of our strategic plan, and both short- and long-term operating objectives. Our hiring, promotion, and retention practices are based on merit and qualifications, guided by the principles of fairness. Our pay practices have strong governance processes, including reviewing competitive market data from multiple surveys each year. We also offer competitive benefits packages that reflect the needs of our workforce, which include medical, dental, and vision plans, prescription benefits, life insurance and disability benefits, HSAs, wellness incentives, health coaching, telemedicine, paid parental leave, paid time off and paid holidays, a matching 401(k) retirement savings plan, an employee stock purchase plan, an employee assistance program, a student loan repayment program, backup child and elder care, pet insurance, and wellness programs.

Our mentoring program, which partners with our Business Resource Group network, is also an important resource to support colleagues with their professional growth based on their self-identified career development goals.

Competition

The Company is subject to strong competition from other commercial banks, savings banks, credit unions, non-bank health savings account trustees, consumer finance companies, investment companies, insurance companies, online lending and savings institutions, and other non-bank financial services companies. Certain of these competitors are larger financial institutions with substantially greater resources, lending limits, larger branch systems, and a wider array of commercial and consumer banking services than the Company. Many of these competitors lack a physical presence within our geographic footprint, but actively pursue business through digital channels and other remote means. Competition could intensify in the future as a result of industry consolidation, the increasing availability of products and services from non-bank organizations, including financial technology companies, greater technological developments in the industry, and continued bank regulatory changes.

The Company faces substantial competition for deposits and loans throughout its market areas. The primary factors in competing for deposits are interest rates, personalized services, the quality and range of financial services, convenience of office locations and hours, mobile banking, and other automated services. Competition for deposits comes from other commercial banks, savings banks, credit unions, non-bank health savings account trustees, money market mutual funds, financial technology companies, and other non-bank financial services companies. The primary factors in competing for commercial and consumer loans are interest rates, loan origination fees, ease and convenience of loan origination channels, the quality and range of lending services, personalized service, and the ability to close within each customer’s desired time frame. Competition for the origination of loans comes primarily from commercial banks, non-bank lenders, savings institutions, mortgage banking firms, mortgage brokers, online lenders, and insurance companies.

The financial services industry continues to undergo rapid technological change with frequent introductions of new technology-driven products and services, including innovative ways that customers can make payments or manage their accounts, such as through the use of mobile payments, digital wallets, or digital assets. Other factors that affect competition include the general and local economic conditions, current interest rate levels, and volatility in the lending markets.

Supervision and Regulation

The Company and its bank and non-bank subsidiaries are subject to extensive regulation under federal and state laws. The regulatory framework applicable to bank holding companies and their depository institutions is intended to protect depositors, the DIF, consumers, and the U.S. banking system as a whole, not stockholders.

Set forth below is a summary of the significant elements of the laws and regulations applicable to the Company and its bank and non-bank subsidiaries. The description that follows is qualified in its entirety by reference to the full text of the statutes, regulations, and policies that are described. Banking statutes, regulations, and policies are continually under review by Congress, state legislatures, and federal and state regulatory agencies. Changes in the statutes, regulations, or policies applicable to the Company and its bank and non-bank subsidiaries, including how they are implemented or interpreted by regulators or by courts, could have a material effect on the results of the Company.

Regulatory Agencies

The Company is a separate and distinct legal entity from the Bank and its other subsidiaries. As a registered bank holding company that has elected to be treated as a financial holding company, the Company is subject to consolidated regulation, inspection, examination, and supervision under the BHC Act by its primary federal regulator, the Federal Reserve. As a publicly-traded company, the Company is subject to the disclosure and regulatory requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended, which are administered by the SEC. As a publicly-traded company with securities listed on the NYSE, the Company is subject to the rules of the NYSE.

The Bank is organized as a national banking association under the National Bank Act, as amended, and is subject to the supervision of and regular examination by the OCC, its primary regulator, and with respect to some matters, by the FDIC, its deposit insurer, and the CFPB. As a national banking association, the Bank derives its lending, investment, and other bank activity powers from the National Bank Act, as amended, and the regulations of the OCC promulgated thereunder.

Table of Contents

The Company’s non-bank subsidiaries are also subject to regulation by the Federal Reserve and other applicable federal and state agencies.

Permissible Activities

In general, the BHC Act limits the business of bank holding companies to banking, managing, or controlling banks and other activities that the Federal Reserve has determined to be closely related to banking. Bank holding companies that qualify and elect to become financial holding companies, such as the Company, may engage in any activity, or acquire and retain the shares of a company engaged in any activity, that is either financial in nature or incidental to such financial activity (as determined by the Federal Reserve in consultation with the Secretary of the Treasury), or complementary to a financial activity, and that does not pose a substantial risk to the safety and soundness of depository institutions or the financial system (as solely determined by the Federal Reserve). Activities that are financial in nature include securities underwriting, dealing and market making, sponsoring mutual funds and investment companies, insurance underwriting, and merchant banking. Subject to certain exceptions, the BHC Act generally prohibits us from acquiring direct or indirect ownership or control of voting shares of any company engaged in activities that are not permissible for financial holding companies to engage in.

Maintaining our financial holding company status requires that the Company and the Bank remain “well-capitalized” and “well managed,” as defined by Regulation Y, and that the Bank maintains at least a “satisfactory” rating under the CRA. If the Company or the Bank fail to continue to meet these requirements, we could be subject to restrictions on new activities and acquisitions, and/or be required to cease and possibly divest operations that conduct existing activities that are not permissible for a bank holding company that is not a financial holding company. Additionally, the Federal Reserve could impose corrective capital and managerial requirements and activity restrictions on us if we cease to be “well-capitalized” or “well managed.”

Acquisitions of Ownership

Acquisitions of Webster voting stock above certain thresholds may be subject to prior regulatory notice or approval under applicable federal banking laws. Investors are responsible for ensuring that they do not, directly or indirectly, acquire shares of Webster stock in excess of the amount that can be acquired without regulatory approval or notice under the BHC Act and the Change in Bank Control Act.

The proposed Transaction with Banco Santander will be subject to relevant regulatory approvals. Refer to the paragraphs captioned under “Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the Transaction” in Part I - Item 1A. Risk Factors for additional information.

Mergers and Acquisitions

Under the BHC Act, prior approval from the Federal Reserve is required in order for any bank holding company to acquire direct or indirect ownership or control of more than 5% of the voting shares of any bank, acquire all or substantially all of the assets of a bank, or merge or consolidate with any other bank holding company. Generally, the Company is not required to obtain prior approval from the Federal Reserve to acquire a non-bank that engages in activities that are financial in nature or incidental to activities that are financial in nature, as long as the Company continues to meet the capital, managerial, and CRA requirements that enable it to qualify as a financial holding company. However, the Company is required to receive prior approval from the Federal Reserve for an acquisition in which the total consolidated assets to be acquired exceeds $10 billion.

Pursuant to Section 18(c) of the FDIA, more commonly known as the Bank Merger Act, and for national banks relying on certain other sources of merger authority, prior written approval from a bank’s primary federal regulator is required before any insured depository institution may consummate a merger transaction, which includes a merger, consolidation, assumption of deposit liabilities, and certain asset transfers between or among two or more institutions. Prior written approval of a bank’s primary federal regulator is also required for merger transactions between or among affiliated institutions, as well as for merger transactions between or among non-affiliated institutions. Transactions that do not involve a transfer of deposit liabilities typically do not require prior approval under the Bank Merger Act unless the transaction involves the acquisition of all or substantially all of an institution’s assets. When evaluating and acting on proposed merger transactions, regulators consider the extent of existing competition between and among the merging institutions, other depository institutions, and other providers of similar or equivalent services in the relevant product and geographic markets, the convenience and needs of the community to be served, capital adequacy and earnings prospects, and the effectiveness the merger institutions in combating money-laundering activities, among other factors.

Further, the Change in Bank Control Act of 1978 prohibits the Company from acquiring control of a bank regulated by the FDIC without providing at least 60 days prior written notice to the FDIC or upon receipt of written notice that the FDIC does not disapprove of the acquisition.

Capital Adequacy

The Federal Reserve, the OCC, and the FDIC have adopted the regulatory capital standards in accordance with the Basel III Capital Rules, as developed by the Basel Committee on Banking Supervision. The Basel III Capital Rules strengthened international capital adequacy standards by increasing institutions’ minimum capital requirements and holdings of
high-quality liquid assets and decreasing bank leverage.

Under the Basel III Capital Rules, as currently adopted in the U.S., the Company’s and the Bank’s assets, exposures, and certain off-balance sheet commitments and obligations are subject to risk weights used to determine risk-weighted assets. Risk weights can range from 0% for U.S. government securities to 1,250% for certain tranches of complex securitization or equity exposures. Risk-weighted assets serve as the base against which regulatory capital is measured, and are used to calculate capital ratios of CET1 Risk-Based Capital, Tier 1 Risk-Based Capital, Total Risk-Based Capital, and Tier 1 Leverage Ratio, as defined in the applicable regulations, which the Company and the Bank are required to maintain above certain specified minimums. CET1 capital consists of common stockholders’ equity less deductions for goodwill and other intangible assets, and certain deferred tax adjustments. At the time of initial adoption of the Basel III Capital Rules, the Company had elected to opt-out of the requirement to include certain components of AOCI in CET1 capital. Tier 1 capital consists of CET1 capital plus preferred stock. Total capital consists of Tier 1 capital and Tier 2 capital, as defined in the regulations. Tier 2 capital includes qualifying subordinated debt and the permissible portion of the ACL.

In addition, the Basel III Capital Rules mandate that most deductions from or adjustments to regulatory capital be made to CET1 capital, not to the other components. For instance, the deduction of mortgage servicing assets, certain DTAs, and capital investments in unconsolidated financial institutions is required to the extent that any one such category exceeds 10% of CET1 capital or exceeds 15% of CET1 capital in the aggregate.

The Basel III Capital Rules also include a capital conservation buffer comprised entirely of CET1 capital, which is considered in addition to the 4.5% minimum CET1 capital ratio and is equal to 2.5% of risk-weighted assets for both the Company and the Bank. This buffer is designed to absorb losses during periods of economic stress, and is generally required in order to avoid limitations on capital distributions and certain discretionary bonus payments to executive officers.

Our regulatory capital ratios can be found in Part II under the section captioned “Liquidity and Capital Resources” contained in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and within Note 13: Regulatory Capital and Restrictions in the Notes to Consolidated Financial Statements contained in Item 8. Financial Statements and Supplementary Data.

Prompt Corrective Action

FDICIA requires the federal bank regulatory agencies to take “prompt corrective action” regarding FDIC-insured depository institutions that do not meet certain capital adequacy standards. A depository institution’s treatment for purposes of the prompt corrective action provisions depends upon its level of capitalization and certain other factors. An institution that fails to remain “well-capitalized” becomes subject to a series of restrictions that increase in severity as its capital condition weakens. Such restrictions may include a prohibition on capital distributions, restrictions on asset growth or restrictions on the ability to receive regulatory approval of applications. FDICIA also provides for enhanced supervisory authority over “under capitalized” institutions, including authority for the appointment of a conservator or receiver for the institution. In certain instances, a bank holding company may be required to guarantee the performance of an “under capitalized” subsidiary bank’s capital restoration plan. As of December 31, 2025, the Bank was categorized as “well-capitalized” under each of its capital ratio categories.

An insured depository institution with a ratio of tangible equity less than or equal to 2% is considered to be critically under capitalized. If an insured depository institution has been determined, after notice and opportunity for a hearing, to be in an unsafe or unsound condition, or if it receives a less-than-satisfactory rating for asset quality, management, earnings, or liquidity in its most recent examination, the appropriate federal banking agency may downgrade a well capitalized, adequately capitalized, or under capitalized insured depository institution to the next lower capital category.

All insured depository institutions, regardless of their capital category, are prohibited from making capital distributions or paying management fees if such distributions or payments would result in the insured depository institution becoming under capitalized, unless it is shown that the capital distribution would improve financial condition, or the management fee is being paid to a person or entity without a controlling interest in the insured depository institution. Restrictions are placed on certain brokered deposit activity and on deposit rates offered as the capital category declines below well capitalized. Further, if an insured depository institution receives notice that it is under capitalized, significantly under capitalized, or critically under capitalized, the insured depository institution generally must file a written capital restoration plan with the appropriate federal banking agency within 45 days of receipt, and the bank holding company must guarantee the performance of that plan.

Enhanced Prudential Standards

The Federal Reserve established enhanced prudential standards for larger bank holding companies based on size and certain risk-based indicators. In 2019, the Federal Reserve, along with other federal bank regulatory agencies, tailored these prudential standards allowing bank holding companies with total consolidated assets of $250 billion or less to be exempt from certain enhanced capital and liquidity prudential standards, including company-run stress testing, capital planning, liquidity coverage ratio, and resolution planning requirements, among others. Although the Company’s total consolidated assets are beneath the $250 billion threshold, the Company performs certain stress tests internally and incorporates the economic models and information developed through its stress testing program into its risk management and capital planning activities, which continue to be subject to the regular supervisory processes of the Federal Reserve System and the OCC.

The transition to heightened supervision under enhanced prudential standards for large banks (e.g., crossing $100 billion of assets, and thus becoming a Category IV institution under the tailoring framework) is a significant regulatory hurdle and involves additional liquidity risk management requirements, more onerous internal liquidity stress testing and liquidity buffer requirements, supervisory stress testing, the stress capital buffer, additional capital planning requirements, additional reporting to the Federal Reserve and more comprehensive resolution plan filings with the FDIC.

Federal Reserve System

Regulations of the Federal Reserve require a depository institution to maintain reserves against its transaction accounts and non-personal time deposits for the purposes of implementing monetary policy. The reserve requirement must be satisfied in the form of vault cash and, if vault cash is insufficient, by maintaining a balance in an account at a FRB. The FRA authorizes different ranges of reserve requirement ratios depending on the amount of transaction account balances held at a depository institution. Since March 26, 2020, the reserve requirement ratios on all net transaction accounts were reduced to zero percent, thereby eliminating reserve requirements for all depository institutions.

Further, as a national bank and a member of the Federal Reserve System, the Bank is required to subscribe to the capital stock of its district FRB in an amount equal to 6% of its capital and surplus, of which 50% is paid. The remaining 50% is subject to call by the Federal Reserve. At December 31, 2025, the Bank held a stock investment in the FRB of New York of $231.2 million.

Federal Home Loan Bank System

The FHLB System provides a central credit facility for its member institutions. The Bank, as a member of the FHLB of Boston, is required to purchase and hold shares of FHLB capital stock for its membership and other activities in an amount equal to 0.05% of total assets as of the end of the prior calendar year, up to a maximum of $5 million, plus an amount that varies from 3.0% to 4.0% depending on the maturities of its FHLB advances, of which there were $3.0 billion outstanding for the Bank at December 31, 2025. The Bank was in compliance with these requirements at December 31, 2025, and held a FHLB stock investment of $125.2 million.

Source of Strength Doctrine

Bank holding companies are required to serve as a source of financial and managerial strength to their subsidiary banks and could be required to commit resources to support each of their subsidiary banks. This support may be required at times when the Company is not in a financial position to provide such resources without adversely affecting its ability to meet other obligations. The Federal Reserve may require a bank holding company to make capital injections into a troubled subsidiary bank and may charge the bank holding company with engaging in unsafe and unsound practices if it fails to commit resources to such a subsidiary bank when necessary, or if it undertakes actions that the Federal Reserve believes might jeopardize the bank holding company’s ability to commit resources to such subsidiary bank when necessary. Capital loans by a bank holding company to its subsidiary bank would be subordinate in right of payment to deposits and certain other debts of the subsidiary bank. In the event of bankruptcy, a formal commitment by a bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank would be assumed by the bankruptcy trustee and entitled to a priority of payment.

In addition, under the National Bank Act, if the Bank’s capital stock is impaired by losses or otherwise, the OCC is authorized to require payment of the deficiency by assessment upon the Company. If the assessment is not paid within three months after receiving notice thereof, the OCC could order a sale of the Bank stock held to cover any deficiency.

Safety and Soundness Standards

The federal bank regulatory agencies have adopted the rules and regulations under the Interagency Guidelines Establishing Standards for Safety and Soundness, which are applicable to all insured depository institutions. These guidelines prescribe standards relating to internal controls, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees, and benefits, asset quality, earnings, and stock valuation, as determined to be appropriate.

Table of Contents

The OCC also has established guidelines setting forth heightened risk management and governance standards for large national banks, which currently includes the Bank. A large bank is currently defined as a bank with more than $50 billion in average total consolidated assets from its four most recently filed quarterly Call Reports. Because the Bank is currently a covered bank, it has a risk governance framework designed to meet the OCC heightened standards. In December 2025, the OCC issued a notice of proposed rulemaking that would increase the threshold at which the heightened standards apply from $50 billion to $700 billion in average total consolidated assets, while keeping in place the concept of a risk governance framework for banks with over $50 billion in average total consolidated assets. Additional information regarding our risk governance framework can be found under the section captioned “Risk Governance Framework” contained elsewhere in this Item 1. Business.

If the applicable federal bank regulatory agency determines that an institution fails to meet any of the established standards, the agency may require the institution to submit an acceptable plan to achieve compliance with the standard. In the event that an institution fails to submit an acceptable plan within the time allowed, or fails, in any material respect, to implement an accepted plan, the agency must require the institution to correct the deficiency and may take other supervisory and enforcement actions until the deficiency is corrected.

In more serious instances, enforcement actions may include the issuance of directives to increase capital, the issuance of formal and informal agreements, the imposition of civil monetary penalties, the issuance of a cease and desist order that can be judicially enforced, the issuance of removal and prohibition orders against officers, directors, and other institution affiliated parties, the termination of the insured depository institution’s deposit insurance, the appointment of a conservator or receiver for the insured depository institution, and injunctions or restraining orders based upon a judicial determination that the FDIC, as receiver, would be harmed if such equitable relief was not granted.

Resolution Planning

The FDIC requires certain insured depository institutions with more than $50 billion in total assets to periodically submit resolution plans to provide the FDIC with information about the bank that is essential to effective resolution planning and to support the execution of a resolution, if necessary. In June 2024, the FDIC amended its insured depository institution resolution plan rule, which requires the Bank, as a “Group B” insured depository institution with between $50 billion and $100 billion in total assets, to submit informational filings on a three-year cycle and provide limited interim supplements in each of the off-years. The final rule became effective October 1, 2024. The Bank’s initial information filing submission is due on or before April 1, 2026. In December 2025, the FDIC provided an update on insured depository institution resolution planning for large banks and announced that it expects to propose changes to the Insured Depository Institution Rule and to conduct capabilities testing in 2026 on insured depository institutions’ ability to populate a virtual data room.

Dividends

The Company is dependent upon dividends from the Bank to provide funds for its cash requirements, including the payment of dividends to stockholders. Dividends paid by the Bank are subject to federal regulatory limitations. Express approval by the OCC is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels or would exceed the net income for that year combined with the undistributed net income for the preceding two years. During the year ended December 31, 2025, the Bank declared and paid $900.0 million in dividends to the Company and had $634.6 million of undistributed net income available for the declaration and payment of dividends at December 31, 2025.

In addition, federal bank regulatory agencies have the authority to prohibit the Company from engaging in unsafe or unsound practices in conducting its business. The declaration and payment of dividends, depending on the financial condition of the Bank, could be deemed an unsafe or unsound practice, especially if its capital base is depleted to an inadequate level. The ability of the Bank to pay dividends in the future is currently, and could be further, influenced by bank regulatory policies and capital requirements.

Transactions with Affiliates and Insiders

Transactions between insured depository institutions and their affiliates are governed by Sections 23A and 23B of the FRA and Federal Reserve Regulation W. In a bank holding company context, at a minimum, the parent holding company of a national bank, and any companies that are controlled by such parent holding company, are considered affiliates of the bank. Generally, sections 23A and 23B of the FRA are intended to protect insured depository institutions from losses arising from transactions with non-insured affiliates by (i) limiting the extent to which an institution or its subsidiaries may engage in covered transactions with any one affiliate and with all affiliates in the aggregate, and (ii) requiring that all such transactions be on terms substantially the same, or at least favorable, to the institution or subsidiary as those provided to a non-affiliate on market terms. The term covered transaction includes the making of loans, purchase of assets, the issuance of a guarantee, and similar types of transactions. Certain covered transactions must be collateralized according to the FRA and Regulation W.

Table of Contents

In addition, Section 22(h) of the FRA and Federal Reserve Regulation O restricts extensions of credit to directors, executive officers, and principal stockholders or insiders of the Bank. Pursuant to Section 22(h), extensions of credit to directors, executive officers, and principal stockholders of the Bank or its affiliates must be made on terms substantially the same as offered in comparable transactions to other persons, except that such insiders may receive preferential extensions of credit made under a benefit or compensation program that is widely available to the institution’s employees and does not give preference to the insider over the employees. Further, extensions of credit to insiders and their related interests may not exceed, together with all other outstanding extensions of credit to such persons and affiliated entities, the percentage of the institution’s total unimpaired capital and unimpaired surplus set forth in Regulation O. Extensions of credit to insiders above specified amounts must receive prior approval from the Bank’s Board of Directors. Section 22(g) of the FRA and Regulation O places additional limitations on extensions of credit to executive officers.

Consumer Protection and Consumer Financial Protection Bureau Supervision

As an insured depository institution with more than $10 billion in total assets, the Bank is subject to supervision by the CFPB. The CFPB has been responsible for implementing, enforcing, and examining compliance with federal consumer financial protection laws. In early February 2025, employees of the CFPB were instructed to cease all supervision, investigations, enforcement, rulemaking, and stakeholder activities. It is unclear how long these instructions — which are the subject of ongoing litigation — will stay in force, either fully or partially. There are also a number of federal laws, which the Bank has been subject to, that are designed to protect borrowers and promote lending, including, but not limited to, the Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Fair Debt Collection Procedures Act, the Truth in Lending Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Practices Act, the Consumer Financial Protection Act of 2010, and the Gramm Leach Bliley Act regarding Privacy of Consumer Financial Information.

In October 2023, the Federal Reserve proposed amendments to its rules on interchange fees. Interchange fees, or “swipe” fees, are charges that merchants pay to card-issuing banks for processing electronic payment transactions. The current interchange fee limitations establish a maximum possible fee for many types of debit interchange transactions that is equal to no more than 21 cents per transaction plus five basis points multiplied by the value of the transaction. The proposed changes would establish a maximum permissible interchange fee of no more than 14.4 cents per transaction plus four basis points multiplied by the value of the transaction. The current rules allow a debit card issuer to recover one cent per transaction for fraud prevention purposes if the issuer complies with certain fraud-related requirements. Under the proposed changes, the fraud prevention adjustment would be increased to 1.3 cents per transaction. The proposed rule would also establish an automatic update of the interchange fee cap every other year based on a survey of debit card issuers. However, the Federal Reserve’s existing interchange fee rule is subject to ongoing litigation and therefore the Federal Reserve has indicated that it does not intend to finalize a new rule until there is legal certainty regarding interpretation of the regulation.

State authorities have increased their focus on and enforcement of consumer protection rules. Consumer protection laws apply to a broad range of our activities and to various aspects of our business and include laws relating to interest rates, fair lending, disclosures of credit terms and estimated transaction costs to consumer borrowers, debt collection practices, the use of and the provision of information to consumer reporting agencies, and the prohibition of unfair, deceptive, or abusive acts or practices in connection with the offer, sale, or provision of consumer financial products and services. The extent to which the Bank as a national bank is also subject to certain state consumer protection laws is also subject to ongoing litigation and uncertainty.

Identity Theft

Certain regulated entities are required to establish programs to address risks of identity theft. In accordance with these rules, financial institutions and creditors are required to develop and implement a written identity theft prevention program designed to detect, prevent, and mitigate identity theft in connection with certain existing accounts or the opening of new accounts. The Company has an Identity Theft Prevention Program in place satisfying its compliance with these requirements.

Financial Privacy and Data Security

The Company is subject to federal and certain state laws and regulations containing consumer privacy and data protection provisions addressing the treatment of nonpublic personal information about consumers by financial institutions. Subject to certain exceptions, financial institutions are prohibited from disclosing nonpublic personal information about a consumer to nonaffiliated third parties, unless the institution satisfies various notice and opt-out requirements, and the consumer has not elected to opt out of the disclosure. Regardless as to whether a financial institution shares nonpublic personal information, the institution must provide notice of its privacy policies and practices to its consumers, and must follow redisclosure and reuse limitations on any nonpublic personal information it receives from a nonaffiliated financial institution.

The federal bank regulatory agencies have adopted guidelines for establishing information security standards and programs to protect such information, with an increased focus on risk management and processes related to information technology, and the use of third parties. The expectation from the federal bank regulatory agencies is that financial institutions have established lines of defense to ensure that their risk management processes address the risks posed by compromised customer credentials, and that the financial institution has sufficient business continuity planning processes to ensure rapid recovery, resumption, and maintenance of operations after a cyber-attack.

Table of Contents

Financial institutions are required to notify customers of security breaches that result in unauthorized access to their nonpublic personal information and its primary regulator of certain types of computer security incidents that result in harm to the confidentiality, integrity, or availability of an information system or the information that the system processes, stores, or transmits, as soon as possible and no later than 36 hours after the banking organization determines that a notification incident has occurred.

Community Reinvestment Act and Fair Lending Laws

The Bank has a responsibility under the CRA to help meet the credit needs of its communities, including low and moderate-income neighborhoods. The CRA does not establish specific lending requirements or programs for financial institutions, nor does it limit an institution’s discretion to develop the types of products or services that it believes are best suited to its particular community. In connection with its examination, the OCC assesses the Bank’s record of compliance with the CRA. In addition, the Equal Credit Opportunity Act and the Fair Housing Act prohibit discrimination in lending practices on the basis of characteristics specified in those statutes. The Bank’s failure to comply with the provisions of the CRA could, at a minimum, result in regulatory restrictions on its activities, as well as the activities of the Company. Further, the Bank’s failure to comply with the Equal Credit Opportunity Act and the Fair Housing Act could result in enforcement actions against it by the OCC, as well as other federal regulatory agencies, including the CFPB and the Department of Justice. The Bank received a CRA rating of Outstanding in its most recent examination.

Federal Deposit Insurance

The standard deposit insurance coverage limit is $250,000 per depositor, per FDIC-insured bank, for each account ownership category, although the FDIC may guarantee uninsured deposits above the $250,000 limit under the statutory systemic risk exception, as was done with the Silicon Valley Bank and Signature Bank failures in March 2023. The DIF is funded mainly through quarterly assessments on insured depository institutions, such as the Bank, and provides insurance coverage for certain deposits up to this maximum amount.

The Bank’s assessment is determined each quarter in accordance with the FDIC’s standardized risk-based methodology by multiplying its assessment rate by its assessment base. The assessment base equals the Bank’s average consolidated total assets less average tangible equity during the assessment period. As a large bank, or generally one with $10 billion or more in assets, the Bank is assigned an individual rate based on a scorecard, which combines CAMELS (capital adequacy, asset quality, management, earnings, liquidity, and sensitivity) component ratings, financial measures used to measure a bank’s ability to withstand asset-related and funding-related stress, and a measure of loss severity that estimates the relative magnitude of potential losses to the FDIC in the event of the bank’s failure, to produce a score that is then converted to an assessment rate.

Assessment rates are subject to adjustment by the FDIC. For instance, assessment rates could (i) decrease for the issuance of long-term unsecured debt, including senior unsecured debt and subordinated debt, (ii) increase for holdings of long-term unsecured or subordinated debt issued by other banks, or (iii) increase for significant holdings of brokered deposits for large banks that are not well rated or not well capitalized. In 2022, the FDIC increased the initial deposit base deposit insurance assessment rate schedules uniformly by 2 basis points for all insured depository institutions, beginning in the first quarterly assessment period of 2023. The increase in assessment rate schedules is intended to increase the likelihood that the reserve ratio of the DIF reaches the statutory minimum of 1.35% by the statutory deadline of September 30, 2028.

In November 2023, the FDIC published a final rule implementing a special assessment for certain banks to recover losses incurred by protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. The special assessment is to be collected for an anticipated total of eight quarterly assessment periods, which began with the second quarter of 2024. In December 2025, the FDIC issued an interim final rule outlining a process for a potential offset to regular quarterly deposit insurance assessments for banks subject to the special assessment if the special assessment amount collected ultimately exceeds losses to the DIF. At December 31, 2025, the Company’s remaining accrual for its estimated special assessment charge was $5.9 million. The FDIC retains the right to cease collection early, extend the special assessment collection period, and impose a final shortfall special assessment if actual losses exceed the amounts collected. Additional information regarding this FDIC special assessment and the Company’s related FDIC special assessment liability can be found within Note 22: Commitments and Contingencies in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

The FDIC may terminate a depository institution’s deposit insurance upon finding that the institution’s financial condition is unsafe or unsound, or that the institution has engaged in unsafe and unsound practices, or has violated any applicable law, regulation, rule, order, or condition imposed by the FDIC. The Company’s management is not aware of any practice, violation, or condition that might lead to the termination of its deposit insurance.

Depositor Preference

In the event of the liquidation or other resolution of an insured depository institution, including the Bank, the claims of depositors of the institution (including any claims of the FDIC as subrogee of depositors) and certain claims for administrative expenses of the FDIC as a receiver will have priority over other general unsecured claims against the institution. If an insured depository institution fails, claims of insured and uninsured depositors, along with claims of the FDIC, would have priority in payment ahead of unsecured, non-deposit creditors, including the Company, with respect to any extensions of credit they have made to such insured depository institution.

Anti Money Laundering

A major focus of U.S. federal governmental policy as it relates to financial institutions is aimed at combating money laundering and terrorist financing. The failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with the relevant laws and regulations, could have serious legal and reputational consequences for the financial institution, including causing the applicable bank regulatory authorities to not approve merger or acquisition transactions or to prohibit such transactions even if prior approval is not required.

Financial institutions are required to take certain measures to identify their customers, prevent money laundering, monitor customer transactions, and report suspicious activity to U.S. law enforcement agencies. Financial institutions also are required to respond to requests for information from federal bank regulatory agencies and law enforcement agencies. Information sharing among financial institutions for the above purposes is encouraged by an exemption granted to complying financial institutions from the privacy provisions of federal privacy laws. Financial institutions that hold correspondent accounts for foreign banks or provide private banking services to foreign individuals are required to take measures to avoid dealing with certain foreign individuals or entities, including foreign banks with profiles that raise money laundering concerns, and are prohibited from dealing with foreign shell banks and persons from jurisdictions of particular concern.

Financial institutions also are required to establish internal anti money laundering programs. The effectiveness of a financial institution in combating money laundering activities is a factor to be considered in any application submitted under the Bank Merger Act. The Company has in place a Bank Secrecy Act and USA PATRIOT Act compliance program and engages in very few transactions of any kind with foreign financial institutions or foreign persons. The Company also complies with the sanctions administered by the OFAC of the U.S. Department of the Treasury, which is responsible for administering economic sanctions that affect transactions with designated foreign countries, nations, and others. The OFAC publishes lists of persons, organizations, and countries suspected of aiding, harboring, or engaging in terrorist acts, known as Specially Designated Nationals and Block Persons. Blocked assets (i.e., property and bank deposits) cannot be paid out, withdrawn, set off, or transferred in any manner without a license from the OFAC. Failure to comply with these sanctions could have serious legal and reputational consequences.

Debit Card Interchange Fees

The Federal Reserve requires that the amount of any interchange transaction fee that a debit card issuer may receive or charge with respect to an electronic debit transaction shall be reasonable and proportional to the cost incurred by the debit card issuer with respect to the transaction, and imposes requirements regarding routing and exclusivity of electronic debit transactions and the usability of debit cards across networks. Interchange fees for certain electronic debit transactions are capped at 21 cents plus 0.05% of the transaction value for issuers with over $10 billion in consolidated assets, such as the Bank. The regulation also allows covered debit card issuers to receive 1 cent per transaction for fraud-prevention costs, provided that the debit card issuer meets the fraud-prevention standards established by the Federal Reserve. For information regarding the Federal Reserve’s proposed amendments to its rules on interchange fees, refer to the paragraphs captioned under “Consumer Protection and Consumer Financial Protection Bureau Supervision” earlier in this section. Interchange fees impact revenues of the Consumer Banking and HSA Bank operating segments, however, HSA Bank’s interchange revenue is not subject to these rules. The regulations that govern interchange fees remains subject to ongoing litigation.

Incentive Compensation

The federal bank regulatory agencies have issued joint guidance on incentive compensation designed to ensure that the incentive compensation policies of banking organizations do not encourage imprudent risk taking and are consistent with the safety and soundness of the organization. We take this guidance into account as part of our compensation practices and enterprise risk management. Additionally, in accordance with federal securities laws and regulations and the continued listed standards for the NYSE, we adopted our Policy for Recoupment of Incentive Compensation for our executive officers as of October 17, 2023, which has been included as Exhibit 97 to this Annual Report on Form 10-K. Dodd-Frank requires the Federal Reserve, the OCC, the FDIC, the SEC, and two other regulatory agencies to adopt regulations governing incentive compensation provided by regulated financial services companies to their executives and other employees. Although regulations to implement these requirements has been proposed multiple times, final regulations have not been adopted.

Fair Access to Financial Services

In recent years, certain states have enacted, or have proposed to enact, statutes, regulations, or policies that prohibit financial institutions from denying or canceling products or services to a person or business, or otherwise discriminating against a person or business in making available products or services, on the basis of certain social or political factors or other activities. In August 2025, Executive Order 14331, “Guaranteeing Fair Banking Access for All Americans,” was signed, which states that it is the policy of the U.S. that no American should be denied access to financial services because of their constitutionally or statutorily protected beliefs, affiliations, or political views. The Executive Order directs the U.S. Treasury Secretary and the federal bank regulatory agencies to address politicized or unlawful debanking activities.

Climate-Related Developments

Climate change and the risks it may pose to financial institutions has, in the recent past, been an area of focus by the federal and state legislative bodies and regulators, including the federal bank regulatory agencies. In the future, new regulations or guidance may be issued, or other regulatory or supervisory actions may be taken, in this area by the federal bank regulatory agencies or other regulatory agencies. In addition, many states have adopted, or are considering adopting, laws that address climate-related and other issues that might arise. These laws may increase our compliance costs and may include provisions that conflict with other state and federal regulations. The Company will continue monitoring legislative and regulatory activity that may implicate potential new legal or regulatory obligations on our part and evaluating their potential impact to Webster.

Risk Governance Framework

Under federal banking laws, the Bank is required to maintain a risk governance framework that ensures the Bank’s risk profile is easily distinguished and separate from that of its parent bank holding company for risk management purposes, and a risk committee, led by an independent director, with at least one risk management expert, that is responsible for the oversight of its enterprise risk management framework and that meets other statutory and regulatory requirements set by the OCC. Under the OCC’s guidelines, the Bank may use the risk governance framework of its parent company if it meets the minimum standards, and the risk profiles of the parent company and the covered bank are substantially the same, along with certain other conditions. The Bank has elected to use the Company’s risk governance framework. The Bank maintains a standing Risk Committee of the Board that meets the OCC’s regulatory requirements to oversee its enterprise risk management framework. In addition, the Enterprise Risk Management Committee, which is the highest management-level risk committee, provides oversight of the risks inherent in Webster’s business and serves as an escalation point for risk topics and issues raised by its seven sub-committees.

At Webster, risk is defined as the potential that events, expected or unexpected, may have an adverse effect on the Company’s earnings, capital, and/or enterprise value. Webster’s risk governance framework, which is aligned with the OCC’s Heightened Standards and the Handbook on Large Bank Supervision, reflects a structured and systematic approach to managing risks and controlling risk-taking activities across the organization.

Risk identification is a continuous process and occurs at various levels throughout the organization. The approaches used to identify risk include process and data analysis, risk metrics, and risk assessments. Risks are categorized using a risk taxonomy and are assessed across all applicable risk categories. This includes an assessment of inherent risk and residual risk after considering the effectiveness of the control environment.

During the year ended December 31, 2025, the Company revised its risk taxonomy to better align with regulatory expectations and industry practices. Specifically, Information Risk was consolidated into Operational Risk, Financial Risk was realigned into Liquidity Risk and Market/Price Risk, and Reputation Risk was consolidated into Strategic Risk. These revisions were primarily administrative in nature, and do not represent a material change in the Company’s underlying risk profile.

Impacts of risk can be both quantitative and qualitative. Risks are mitigated through the establishment of robust controls, and documented policies and related procedures. A control is a specific activity, procedure, tool, or technical standard designed to satisfy the control objective and implemented within a business process to mitigate the impact and likelihood of associated inherent risk. For risks that cannot be controlled, First Line of Defense management may decide to accept the risks with agreement from relevant Second Line of Defense management, reduce the level of business activity, share or transfer the risks, or withdraw from the activity altogether.

Webster maintains a Risk Appetite Statement, which is a key component of its risk governance framework as it links the monitoring and reporting of risks, at the enterprise level, with Webster’s business strategy and financial objectives by providing the organization with expectations of the type and level of risk it is willing to accept in pursuit of its objectives. The Risk Appetite Statement establishes a risk appetite across Operational, Credit, Compliance, Liquidity, Market/Price, and Strategic as Level 1 risk categories, which represent the top risks that drive Webster’s risk profile, and uses a 5-point rating scale (minimal to critical). Further delineation and detail is provided at Level 2 and Level 3 to enable more precise risk identification, assessment, and response. The Risk Appetite Statement includes a set of qualitative risk statements and quantitative Board-level metrics along with Board-level tolerances, which are approved by the Board annually. Breaches of approved tolerances are required to be escalated and addressed in a timely manner.

The Chief Executive Officer is ultimately responsible for all of Webster’s risk-taking activities and for supporting an effective enterprise risk management framework that is adopted, operationalized, and executed. The Chief Executive Officer sets the tone at the top and reinforces a strong risk culture that values risk self-identification and for holding executives accountable for their adherence to the enterprise risk management framework, appropriately assessing and effectively managing all of the risks associated with their activities and operating within the established risk appetite.

The Company has adopted the Three Lines of Defense Model. Under this model, the First Line manages risks, verifies compliance, performs control activities, and works in coordination with the Second Line. The Second Line provides expertise, support, and tools, and challenges the First Line to enhance efficiency and effectiveness of the control environment. The Third Line provides independent and objective assurance to management and the Board, assessing whether the First and Second Line functions are operating effectively. Detailed roles and responsibilities for each line are as follows:

*First Line of Defense: Front-Line Units represent process owners that engage in activities designed to generate revenue and reduce expenses, provide operational and technology services, and provide operational support and servicing in the delivery of products or services. Since Front-Line Unit activities inherently create risk, the Front-Line Units are responsible for assessing and managing that risk.

*Second Line of Defense: Independent Risk Management is responsible for identifying, measuring, monitoring, or controlling risks independently from the Front-Line Units and providing effective challenge to the Front-Line Units. Independent Risk Management includes Enterprise Risk, Operational Risk, Corporate Compliance, Enterprise Financial Crime, and Credit Risk Review, which report to the Chief Risk Officer, and Credit Risk Management, which reports to the Chief Credit Officer. The Chief Risk Officer and the Chief Credit Officer are Webster’s Chief Risk Executives.

*Third Line of Defense: Internal Audit independently assesses Webster’s risk management processes and controls using methodology developed from professional auditing standards and regulatory guidance. Internal Audit undertakes these responsibilities through periodic reviews of Webster’s business activities, operations, and systems, and through special or retrospective reviews that may be specifically requested by the Audit Committee or management. The Chief Audit Executive leads Internal Audit.

In December 2025, the OCC issued a notice of proposed rulemaking that would increase the threshold at which the heightened standards apply from $50 billion to $700 billion in average total consolidated assets, while keeping in place the concept of a risk governance framework for banks with over $50 billion in average total consolidated assets.

Credit Risk

Credit risk is the risk of loss that arises when a client or counterparty fails to honor its financial or contractual obligations to Webster and/or the underlying collateral is insufficient to satisfy the obligation. Credit risk arises in Webster’s lending operations, and in its funding and investment activities where counterparties have repayment or other obligations to Webster. Credit risk can also arise from deposit overdrafts and other solutions or services that involve customer obligations for the transfer of funds.

The overall focus of credit risk management is to identify, measure, monitor, and control credit risk at the portfolio and enterprise level. Webster maintains underwriting standards consistent with its desired risk profile and robust credit processes. Webster’s loan portfolio is balanced to include both commercial and consumer lending activity while closely managing concentrations in borrowers, counterparties, industries, geographies, and collateral asset classes to avoid excessive correlated risk. Diversification of the loan portfolio across commercial and industrial, commercial real estate, and consumer is important in managing credit risk. Accordingly, management aims to actively measure and manage concentrations by portfolio, industry sector, and specific sub-sectors, geography, affiliated obligors, and other common characteristics. Webster is primarily a relationship lender. In addition, Webster will only assume credit risk when it can be effectively managed from an infrastructure or operational perspective, and it has industry, product, and market expertise.

Credit Risk at Webster includes:

–Credit Concentration Risk – The risk of financial loss due to overly concentrated exposure to borrowers and/or counterparties that have common characteristics, such as industry, geography, or collateral asset class.

–Credit Quality Risk – The risk of financial loss due to a decline in a borrower or counterparties creditworthiness, default due to lack of willingness or ability to meet financial obligations, or asset quality deterioration.

The Chief Credit Officer is responsible for credit risk oversight. The Credit Risk Management Committee is also responsible for providing oversight and governance of credit risk for the Bank.

Liquidity Risk

Liquidity Risk is the potential inability to meet contractual or contingent obligations as they arise without incurring significant losses. Liquidity Risk at Webster includes:

–Capital Adequacy Risk – The risk that the bank does not have enough capital to absorb losses and support its operations, putting its solvency, stability, and regulatory compliance at risk.

–Funding Risk – The risk that the Bank will be unable to issue new debt to meet funding needs or repay existing debt as it comes due.

–Structural Mismatch Risk – The risk of misalignment of cash flow timing between assets and liabilities, potentially leading to operational difficulties and financial losses.

Liquidity is monitored by considering the adequacy of liquidity sources and by considering present and future needs under various operating conditions, including extreme stress. Additionally, Webster aims to maintain capital levels that are consistent with supervisory expectations and commensurate with the risk profiles of our portfolios for a range of stress scenarios.

Market/Price Risk

Market/Price Risk is the risk of loss arising from changes in external market variables such as interest rates, foreign exchange rates, equity prices, asset values, and collateral values. Market/Price Risk at Webster includes:

–Investment Risk – The risk of significant changes in interest rates leading to fluctuations in the market value or prices of investments, potentially resulting in financial losses or capital deterioration.

–Interest Rate Risk – The risk arising from significant changes in interest rates that could have a material adverse impact on the Company’s earnings or equity.

Interest rate exposure is actively monitored by measuring sensitivity of earnings and equity to changing interest rates and managed using investment portfolio positioning, wholesale funding mix, and interest rate contracts to ensure stable earnings and capital in changing interest rate environments.

The Chief Financial Officer, along with ALCO, are responsible for providing oversight and governance of both liquidity risk and market/price risk.

Operational Risk

Operational risk is the risk of loss resulting from inadequate or failed internal processes, people, and systems, or from external events. Operational risk at Webster includes:

–Business Disruption Risk – The risk of disruption to business activities that prevents the execution of critical operations required to service clients, support products, and satisfy other external obligations.

–Corporate Practices Risk – The risk that arises from failing to adhere to expected regulatory and financial market practices, including accurate and timely reporting, corporate tax filing, document retention/destruction, and effective risk management practices.

–Data Risk – The risk arising from inappropriate or inadequate collection, storage, processing, use, sharing, or disposal of information and data, including availability of data to support business processes.

–External Fraud Risk – The risk of loss due to acts intended to defraud, misappropriate property, or circumvent regulations, laws, or company policies by an external party.

–Human Capital Risk – The risk of loss of key personnel, skills shortages, and knowledge management which could potentially impact Webster’s ability to execute on its key strategic initiatives, facilitate a desired risk culture, competitive position in the marketplace, and business operations.

–Information Security Risk – The risk of unauthorized access, use, disclosure, disruption, modification, perusal, inspection, recording, or destruction of electronic or physical data.

–Information Technology Risk – The risk that systems handling information and process flow may not meet quality, availability, and efficiency standards in line with industry, client, and regulatory expectations, or may fail causing outages, or that new systems may not be implemented timely.

–Internal Fraud Risk – The risk of loss due to acts intended to defraud, misappropriate property, or circumvent regulations, laws, or company policies which involve at least one internal party (e.g., colleague, former colleague, contractor).

–Model Risk – The risk that arises from errors within a model and/or incorrect use of a model, while considering the degree of reliance on model output in decision making.

–Physical Security Risk – The risk that arises from the inability to protect Webster’s assets, including infrastructure and people, from criminal injury or natural and/or manmade disasters that would impair its ability to operate.

–Processing Risk – The risk of failing to appropriately and timely process transactions on behalf of clients, colleagues, or the company, service client accounts, or manage technology and non-technology related change initiatives.

–Third-Party Risk – The risk of failing to manage third-party relationships resulting in an incident or vulnerability with a service being provided by or on behalf of a third-party provider.

Webster mitigates operational risk through an operational risk management framework, which provides a set of tools to identify, assess, monitor, control, and report on operational risk. The operational risk management framework enables the lines of business and corporate functions to establish accountability for the timely and effective management of identified risks, control failures, or other related gaps/deficiencies. Webster seeks to control operational risk within an acceptable range, determined by the types of businesses in which it engages. Control of operational losses depends on identifying the types of transactions and operational risks faced at the enterprise and business level, and ensuring effective internal control processes are in place to mitigate these risks.

The Head of Operational Risk is responsible for operational risk oversight. Additionally, the Operational Risk Management Committee is responsible for providing oversight and governance of Operational risk. Further, the Information Risk Committee is specifically responsible for providing oversight and governance of information security and information technology risks.

Compliance Risk

Compliance risk is the risk arising from non-adherence to applicable laws, rules, regulations, and other supervisory guidance. It risk exposes Webster to fines, civil monetary penalties, payment of damages, and the voiding of contracts. Compliance Risk at Webster includes:

–Conduct Risk – The risk associated with the conduct and behavior of individuals and organizations.

–Consumer Compliance Risk – The risk associated with failing to comply with regulations and laws that protect consumers.

–Fiduciary Compliance Risk – The risk associated with failing to uphold fiduciary duties when managing client investments and trust accounts.

–Financial Crimes Risk – The risk associated with illicit activities and criminal behaviors within the financial industry.

–Legal Risk – The risk arising from potential legal action due to colleague or corporate actions, improperly licensed legal entities, failure to meet Board’s requirements, and non-compliance with laws or regulations.

–Prudential Regulatory Risk – The risk associated with failing to comply with prudential regulatory requirements, potentially undermining confidence in the company.

Corporate Compliance manages compliance risk through the execution of a comprehensive Compliance Management Program, which is designed to identify and evaluate risks of non-compliance, assess, test, and monitor the effectiveness of internal controls, and report and escalate significant regulatory compliance risks and issues.

The Chief Compliance Officer is responsible for compliance risk oversight. The Regulatory Compliance Committee is responsible for providing oversight and governance of compliance risk.

Strategic Risk

Strategic risk is the risk associated with the Company’s mission and future business plans and includes the current or prospective risk to capital and earnings arising from changes in the business environment and from adverse business decisions, improper implementation of decisions, or lack of responsiveness to changes in the business environment. Strategic Risk at Webster includes:

–Strategy Consistency & Effectiveness Risk – The risk associated with the potential for the strategic plan or approach to be inconsistent or ineffective in achieving desired outcomes or business objectives. The chosen strategy may not be well-aligned with the Company’s goals, competitive landscape, or changing market conditions, leading to suboptimal results.

–Reputational Risk – The risk arising from negative perception of the company among clients, colleagues, investors, governments, regulators, and other external parties.

Webster manages strategic risk through a disciplined process led by Webster’s Chief Strategy Officer. This process ensures that strategic choices and initiatives align with Webster’s strategic risk management framework and overarching goal of allocating capital and resources to support strategies that create value for customers and sustainably grow economic profit over time. Management decisions include selecting strategic priorities, applying planning assumptions, assessing internal capabilities and external conditions, and dedicating resources to execution. Changes and updates to strategic choices and supporting initiatives are reviewed by the Board along with the Company’s priorities. The impact of strategies on Webster’s risk appetite and risk profile is evaluated in collaboration with independent risk management functions as part of the strategic planning process.

Risks Related to the Proposed Transaction with Banco Santander

Failure to complete the Transaction could negatively affect our stock price and our future business and financial results.

If the Transaction is not completed for any reason, our ongoing business may be adversely affected and, without realizing any of the benefits of having completed the Transaction, we would be subject to a number of risks, including, among others the following:

•negative reactions from the financial markets, including a decline in our stock price to the extent that current market prices reflect a market assumption that the Transaction will be completed;

•negative reactions from our customers and vendors;

•the incurrence of substantial expenses in connection with the negotiation of the Transaction Agreement and the requirement to pay certain costs relating to the Transaction, including legal, accounting, and other fees, whether or not the Transaction is completed; and

•the failure to pursue other beneficial opportunities due to the focus of our management team on the Transaction and the substantial time and resources dedicated to matters relating to the Transaction.

Moreover, if Banco Santander terminates the Transaction Agreement because our Board withdraws or modifies or qualifies its recommendation that our stockholders vote in favor of the Transaction, we may be required to pay a termination fee of $489.0 million to Banco Santander.

We will be subject to business uncertainties and contractual restrictions while the Transaction is pending.

Uncertainty about the effect of the Transaction on our employees and customers may have an adverse effect on us. These uncertainties may impair our ability to attract, retain, and motivate key personnel until the Transaction is completed, and could cause customers and others that deal with us to seek to change existing business relationships with us. In addition, subject to certain exceptions, we have agreed to operate our business in the ordinary course, in all material respects, and to refrain from taking certain actions that may adversely affect our ability to consummate the Transaction on a timely basis without the consent of Banco Santander. These restrictions may prevent us from pursuing attractive business opportunities that may arise prior to the completion of the Transaction. Employee retention may be particularly challenging during the pendency of the Transaction, as employees may experience uncertainty about their roles with the surviving corporation following the Transaction. All of these risks may be exacerbated if the Transaction is not timely consummated.

Because the market price of ADSs (or Ordinary Shares, as applicable) may fluctuate, our stockholders cannot be certain of the precise value of the consideration they may receive in the Transaction.

Upon the completion of the Transaction, each issued and outstanding share of our common stock (other than certain shares held by us or Banco Santander) will be converted into the right to receive 2.0548 ADSs (or Ordinary Shares in certain circumstances). This exchange ratio is fixed and will not be adjusted for fluctuations in the market values of our common stock, Ordinary Shares, or corresponding ADSs that may occur during the time period between the execution of the Transaction Agreement and the completion of the Transaction. We are not permitted to terminate the Transaction Agreement as a result, in and of itself, of fluctuations in such market values. Fluctuations in such market values may occur as a result of a variety of factors, including general market and economic conditions and changes in our and Banco Santander’s businesses, operations, and prospects, and regulatory considerations. Many of these factors are outside of our and Banco Santander’s control. The actual value of the Ordinary Shares and corresponding ADSs received by our stockholders will depend on the respective market values of our common stock, Ordinary Shares, and corresponding ADSs at the time the Transaction is completed. This market value may be less or more than the value used to determine the exchange ratio stated in the Transaction Agreement and the proxy statement/prospectus.

The Transaction Agreement may be terminated and the Transaction may not be completed.

The Transaction Agreement is subject to a number of customary closing conditions, including (1) receipt of the requisite Webster and Banco Santander stockholder approvals, (2) authorization for listing on the NYSE of the ADSs, subject to official notice of issuance, (3) receipt of required regulatory approvals, including the approval of the Federal Reserve and the European Central Bank, (4) the effectiveness of the registration statement on Form F-4 for the Ordinary Shares and corresponding ADSs, (5) the filing of an exemption document or prospectus with the National Securities Market Commission of Spain, (6) Banco Santander’s receipt of a required report from an independent expert under Spanish law validating the valuation of the common stock of Webster Virginia Corporation used to determine the exchange ratio, (7) the grant of a deed of capital increase before a Spanish public notary, and (8) the absence of any order, injunction, decree, or other legal restraint preventing the completion of Transaction, or any of the other transactions contemplated by the Transaction Agreement, or making the completion of the Transaction or any of the other transactions contemplated by the Transaction Agreement illegal. Each party’s obligation to complete the merger of Webster and Webster Virginia Corporation is also subject to certain additional customary conditions, including subject to certain exceptions, the accuracy of the representations and warranties of the other party and performance, in all material respects, by the other party of its obligations under the Transaction Agreement. Conditions to the closing of the Transaction may not be fulfilled in a timely manner or at all, and, accordingly, the Transaction may be delayed or may not be

completed. In addition, we and/or Banco Santander may elect to terminate the Transaction Agreement under certain circumstances.

Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the Transaction.

Before the Transaction may be completed, various approvals, consents, and non-objections that have not yet been obtained must be obtained, including from the Federal Reserve and the European Central Bank. In determining whether to grant these approvals, such regulatory authorities consider a variety of factors, including the regulatory standing of each party. These approvals could be delayed or not obtained at all, including due to an adverse development in either party’s regulatory standing or in any other factors considered by regulators when granting such approvals; governmental, political or community group inquiries, investigations or opposition; or changes in legislation or the political environment generally.

The approvals that are granted may impose terms and conditions, limitations, obligations, or costs, or place restrictions on the conduct of the combined company’s business or require changes to the terms of the transactions contemplated by the Transaction Agreement. There can be no assurance that regulators will not impose any such conditions, limitations, obligations, or restrictions and that such conditions, limitations, obligations, or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the Transaction Agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the Transaction or otherwise reducing the anticipated benefits of the Transaction if the Transaction were consummated successfully within the expected timeframe. In addition, there can be no assurance that any such conditions, terms, obligations, or restrictions will not result in the delay or abandonment of the Transaction. Additionally, the completion of the Transaction is conditioned on the absence of certain orders, injunctions, or decrees by any court or regulatory agency of competent jurisdiction that would prohibit or make illegal the completion of any of the transactions contemplated by the Transaction Agreement.

In addition, despite the parties’ commitments to using their reasonable best efforts to comply with conditions imposed by regulators, under the terms of the Transaction Agreement, neither us nor Banco Santander, nor any of their respective subsidiaries, is required to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the required permits, consents, approvals, and authorizations of governmental entities that would reasonably be expected to have a material adverse effect on us and our subsidiaries, taken as a whole, or on Banco Santander and its subsidiaries (including, from and after the completion of the Transaction, Webster Virginia Corporation and its subsidiaries), taken as a whole.

We have incurred, and are expected to incur, substantial costs related to the Transaction and related integration.

We have incurred, and expect to incur, a number of non-recurring costs associated with the Transaction. These costs include, or will include, legal, financial advisory, accounting, consulting, and other advisory fees; retention, severance, and employee benefit-related costs; public company filings fees and other regulatory fees; financial printing and other printing costs. Some of these costs are payable by us regardless of whether or not the Transaction is completed.

Combining us and Banco Santander may be more difficult, costly, or time-consuming than expected, and the combined company may fail to realize the anticipated benefits of the Transaction.

The success of the Transaction will depend, in part, on the ability to realize the anticipated revenue and cost synergies from combining the businesses of us and Banco Santander. To realize the anticipated revenue and cost synergies from the Transaction, we and Banco Santander must successfully integrate and combine the businesses in a manner that permits those revenue and cost synergies to be realized without adversely affecting current revenues and future growth. If we and Banco Santander are not able to successfully achieve these objectives, the anticipated benefits of the Transaction may not be realized fully, or at all, or may take longer to realize than expected. In addition, the revenue and cost synergies of the Transaction could be less than anticipated, and integration may result in additional and unforeseen expenses.

An inability to realize the full extent of the anticipated benefits of the Transaction and the other transactions contemplated by the Transaction Agreement, as well as any delays encountered in the integration process, could have an adverse effect upon the revenues, levels of expenses and operating results of the combined company following the completion of the Transaction, which may adversely affect the values of the Ordinary Shares and corresponding ADSs following the completion of the Transaction.

We and Banco Santander have operated and, until the completion of the Transaction, must continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures, and policies that adversely affect the companies’ ability to maintain relationships with merchants, merchant acquirers, clients, customers, depositors, and employees or to achieve the anticipated benefits and cost savings of the Transaction. Integration efforts between the companies may also divert management attention and resources. These integration matters could have an adverse effect on us during this transition period and for an undetermined period after completion of the Transaction on the combined company.

Risks Related to Credit

Our allowance for credit losses on loans and leases may be insufficient.

We maintain an ACL on loans and leases, which is a reserve established through a provision for credit losses charged to expense, that represents management’s best estimate of expected credit losses over the life of the loan or lease within our existing portfolio. The determination of the appropriate level of ACL on loans and leases inherently involves a high degree of subjectivity and requires us to make significant estimates of current credit risks and trends using existing qualitative and quantitative information and reasonable supportable forecasts of future economic conditions, all of which may undergo frequent and material changes. Changes in economic conditions affecting borrowers, the softening of macroeconomic variables that we are more susceptible to, along with new information regarding existing loans, identification of additional problem loans, and other factors, both within and outside our control, may indicate the need for an increase in the ACL on loans and leases.

Bank regulatory agencies also periodically review our ACL and may require an increase in the provision for credit losses or the recognition of additional loan charge-offs, based on judgments different than those of management. In addition, if charge-offs in future periods exceed the ACL, we may need, depending on an analysis of the adequacy of the ACL, an additional provision to increase the ACL. An increase in the ACL would result in a decrease in net income, and could have a material adverse effect on our financial condition, results of operations, and regulatory capital position.

The Company has established processes and procedures intended to identify, measure, monitor, report, and analyze the types of risk to which it is subject, including credit risk, liquidity risk, market/price risk, among others. There are inherent limitations to the Company’s risk management strategies as there may exist, or may develop in the future, risks that it has not appropriately anticipated or identified. In addition, the Company relies on both qualitative and quantitative factors, including models, to monitor, measure and analyze certain risks and to estimate certain financial values, which are subject to error. The Company must also develop and maintain a culture of risk management among its employees, as well as manage risks associated with third parties, and could fail to do so effectively. If the Company’s risk framework proves ineffective, the Company could incur additional credit losses and an additional provision to increase the ACL. An increase in the ACL would result in a decrease in net income, and could have a material adverse effect on our financial condition, results of operations, and regulatory capital position.

The soundness of other financial institutions and other third parties, actual or perceived, could adversely affect our business.

Adverse developments affecting the overall strength and soundness of our competitors, the financial services industry as a whole and the general economic climate and the U.S. Treasury market could have a negative impact on perceptions about the strength and soundness of our business even if we are not subject to the same adverse developments. In addition, adverse developments with respect to third parties with whom we have important relationships also could negatively impact perceptions about us. These perceptions about us could cause our business to be negatively affected and exacerbate the other risks that we face. Moreover, the speed with which information spreads through news, social media and other sources on the Internet and the ease with which customers transact may amplify the onset and negative effects from such perceptions, such as rapid deposit withdrawals or other outflows.

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. We have exposure to many different industries and counterparties, and we routinely execute transactions with counterparties in the financial services industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds, and other institutional clients. As a result, defaults by, or even speculation regarding fragility at one or more financial services companies, or the financial services industry in general, have led, and may further lead to market-wide liquidity problems and could lead to losses or defaults by us or by other institutions. Many of our transactions with other financial institutions could expose us to credit risk in the event of default of our counterparty or client. In addition, our credit risk may be impacted if the collateral held by us cannot be realized or is liquidated at prices not sufficient to recover the full amount of our investment in the financial instrument. Any such losses could materially or adversely affect our business, financial condition, or results of operations.

We are subject to the risk of default by our counterparties and clients, particularly with respect to certain types of commercial loans.

Many of our routine transactions expose us to credit risk in the event of default of our counterparties or clients. Our credit risk may be exacerbated when the collateral held cannot be realized or is liquidated at prices insufficient to cover the full amount of the loan or derivative exposure to us. In deciding whether to extend credit or enter into other transactions, we may rely on information furnished by or on behalf of counterparties and clients, including financial statements, credit reports, and other information. We may also rely on representations of those counterparties, clients, or other third parties, such as independent auditors, as to the accuracy and completeness of that information. The inaccuracy of that information or those representations affects our ability to evaluate the default risk of a counterparty or client accurately and could cause us to enter into unfavorable transactions, which could have a material adverse effect on our financial condition and results of operations.

In addition, we consider our commercial real estate loans and commercial and industrial loans to be higher risk categories in our loan portfolio because these loans are particularly sensitive to economic conditions. Commercial real estate loans generally have large balances and can be significantly affected by adverse economic conditions that are outside of the borrower’s control because payments on such loans typically depend on the successful operation and management of the businesses that hold the loans. In recent years, commercial real estate has been impacted by higher interest rates and inflation, which affected the profitability of new commercial real estate developments, the feasibility of some projects, and the volume of commercial real estate investments. The commercial real estate market has experienced increased property vacancies and declining rent growth. In the case of commercial and industrial loans, related collateral often consists of accounts receivable, inventory, and equipment. This type of collateral typically does not yield substantial recovery in the event of foreclosure and may rapidly deteriorate, disappear, or be misdirected in advance of foreclosure. In addition, many of our commercial real estate and commercial and industrial borrowers have more than one loan outstanding with us. Consequently, an adverse development with respect to one loan or one credit relationship may expose us to significantly greater risk of loss. The risks associated with these types of loans could have a significant negative affect on our earnings in any quarter, which could have a material adverse affect on our business, financial condition, and results of operations.

During periods of market stress or illiquidity, our credit risk may be further increased when we fail to realize the fair value of the collateral we hold; collateral is liquidated at prices that are not sufficient to recover the full amount owed to us; or counterparties are unable to post collateral, whether for operational or other reasons. Furthermore, disputes with counterparties concerning the valuation of collateral may increase in times of significant market stress, volatility or illiquidity, and we could suffer losses during these periods if we are unable to realize the fair value of collateral or to manage declines in the value of collateral.

We are subject to commercial lending concentration risks.

At December 31, 2025, approximately 75% of our loan and lease portfolio consisted of commercial non-mortgage, commercial real estate, and multi-family loans, and a large portion of the borrowers or properties associated with these loans are geographically concentrated in New York City and proximate areas. We continue to monitor risks associated with office space, anchor tenants, and the general economic and physical risks (such as severe weather, public health, and personal safety risks), affecting commercial properties and borrowers in the Greater New York City area. Additional information regarding our commercial lending business can be found in Part II under the section captioned “Loans and Leases” contained in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

A general decline in property values would adversely affect the value of collateral securing the real estate that we hold, as well as the volume of loan originations and the amount we realize on the sale of real estate loans. Additionally, if insurance obtained by our borrowers is insufficient to cover any losses sustained to the collateral, the decreases in the value of collateral securing our loans as a result of natural disasters or other related events could adversely impact our financial condition and results of operations. If insurance coverage is unavailable to our borrowers due to the reluctance of insurance companies to renew policies covering the collateral or due to other factors, the resulting increase in cost of property ownership could affect the ability of borrowers to repay loans. These factors could result in higher delinquencies and greater charge-offs in future periods, which could materially adversely affect our business, financial condition or results of operations.

Risks Related to Liquidity

Realized and unrealized losses in our financial instruments, including in both our available-for-sale securities portfolio and held-to-maturity securities portfolio, could negatively impact our business, financial condition, and results of operations.

We have a large portfolio of financial instruments, including loans and leases, loan commitments, available-for-sale and held-to-maturity debt securities, derivative assets and liabilities, and non-marketable equity securities that are subject to valuation and impairment assessments. Certain of these financial instruments are measured at fair value and may be subject to considerable fluctuation resulting from, for example, perceived changes in the value of the asset, the volume of trading of the asset, shifts in investor sentiment, and general market conditions. Due to these kinds of fluctuations, the amount that we realize on a financial instrument in a subsequent period may significantly differ from the last reported value. Our access to liquidity sources, financial condition, and results of operations could be affected by unrealized losses if securities must be sold at a loss. Changes in interest rates or interest rate spreads may also affect the Company’s ability to hedge various forms of market and interest rate risk, and may decrease the profitability or protection, or increase the risk or cost associated with such hedges. Additionally, significant unrealized losses could negatively impact market and/or customer perceptions of us, which could lead to a loss of depositor confidence and result in an increase in withdrawals, particularly among those with uninsured deposits.

In addition, we experienced significant unrealized losses on our available-for-sale securities portfolio as market rates increased over the past few years. Unrealized losses related to available-for-sale securities are reflected in AOCL in our Consolidated Balance Sheets and reduce the level of our tangible common equity. Such unrealized losses do not affect our regulatory capital ratios. We actively monitor our available-for-sale securities portfolio and believe that it is not more likely than not that we will be required to sell securities before the recovery of the amortized cost basis.

The proportion of our deposit account balances that exceed the FDIC insurance limits may expose the Bank to enhanced liquidity risk in times of financial distress.

Various assessments of the failures of Silicon Valley Bank, Signature Bank, and First Republic Bank in the first half of 2023 concluded that a significant contributing factor to the failures was the proportion of deposits held by each institution that exceeded FDIC insurance limits.

In response to the failures of Silicon Valley Bank, Signature Bank, and First Republic Bank, many large depositors across the industry withdrew deposits in excess of the applicable deposit insurance limits and deposited these funds in other financial institutions. If a significant portion of our deposits were to be withdrawn within a short period of time such that additional sources of funding would be required to meet withdrawal demands, the Company may be unable to obtain funding at favorable terms, which may have an adverse effect on our net interest margin. Additionally, obtaining adequate funding to meet our deposit obligations may be more challenging during periods of elevated prevailing interest rates. In addition to customer deposits, sources of liquidity include brokered deposits, repurchase agreements, the FHLB of Boston, and the FRB of New York, as well as the debt and equity capital markets. Interest rates paid on these additional sources of liquidity generally exceed interest rates paid on deposits. Our ability to attract and retain depositors during a time of actual or perceived distress of instability in the marketplace may be limited.

A reduction in our credit rating could adversely affect our access to capital and could increase our cost of funds.

The credit rating agencies regularly evaluate the Company and the Bank, and credit ratings are based on a number of factors, including our financial strength and ability to generate earnings, as well as factors not entirely within our control, including conditions affecting the financial services industry, the economy, and changes in rating methodologies. There can be no assurance that we will maintain our current credit ratings. A downgrade of our credit ratings could adversely affect our access to liquidity and capital, and could significantly increase our cost of funds, trigger additional collateral or funding requirements, and decrease the number of investors and counterparties willing to lend to us or purchase our securities. In particular, if we were to be downgraded below investment grade, we may not be able to reliably access the short-term unsecured funding markets, and certain customers could be prohibited from placing deposits with the Bank, which could cause us to hold more cash and liquid investments to meet our ongoing needs. Additionally, if we were to be downgraded to below investment grade, certain counterparty contracts may be required to be renegotiated or require posting of additional collateral. This could affect our growth, profitability, and financial condition, including liquidity.

We may be subject to more stringent capital and liquidity requirements, which could limit our business activities.

The Company and the Bank are subject to capital and liquidity requirements imposed by statute and the rules and regulations promulgated by the federal bank regulatory agencies. Regulators have proposed and may implement changes to these requirements. Potential revisions to the applicable regulations remain uncertain. If we fail to meet the minimum capital adequacy and liquidity guidelines and other requirements, our business activities, including lending and our ability to expand, either organically or through acquisitions, could be limited. Any changes in the applicable regulations could also result in us being required to take steps to increase our regulatory capital that may be dilutive to stockholders or limit our ability to pay dividends, or sell or refrain from acquiring assets.

Our ability to grow is contingent upon access to capital, which may not be readily available to us.

We may not be able to maintain adequate sources of funding and liquidity to fund our operations, grow our business, pay our outstanding liabilities, and meeting regulatory expectations. Our ability to borrow from other financial institutions or access the capital markets, if needed, will depend on a number of factors outside of our control, including the state of the financial markets. Heightened interest rates, disruptions in financial markets, negative perceptions of our business or our financial strength, negative perceptions of the overall banking industry or of other regional banks, or other factors may impact our ability to raise additional capital, if needed, on terms acceptable to us or at all. For example, in the event of future turmoil in the banking industry or other idiosyncratic events, there is no guarantee that the U.S. government will invoke the systemic risk exception, create additional liquidity programs, or take any other action to stabilize the banking industry or provide liquidity. Any diminished ability to access short-term funding or capital markets to raise additional capital, if needed, could subject us to liability, restrict our ability to grow, require us to take actions that would affect our earnings negatively or otherwise adversely affect our business and our ability to implement our business plan, capital plan and strategic goals.

Risks Related to Market/Price

Difficult conditions or volatility in the U.S. economy and financial markets may have a materially adverse effect on our business, financial condition, and results of operations.

As a financial services company, our business and overall financial performance is highly dependent upon the U.S. economy and strength of its financial markets. Difficult economic and market conditions could adversely affect our business, results of operations, and financial condition.

22

Table of Contents

The risks associated with our business become more acute in periods of a slowing economy or slow growth. In particular, we could face some of the following risks in connection with adverse economic conditions in the U.S. economic and market environment:

•loss of confidence in the financial services industry and the debt and equity markets by investors, placing pressure on our common share price;

•decreased consumer and business confidence levels may decrease the demand for credit and investment, or increase in delinquencies and default rates;

•decreased household or corporate incomes, which could reduce customer purchasing power, confidence and spending, as well as demand for our products and services;

•decreased value of collateral securing loans to borrowers, causing a decrease in the asset quality of our loan and lease portfolio and/or an increase in charge-offs;

•changes in usage of commercial real estate, which may have sustained negative impact on utilization rates and values;

•decreased confidence in the creditworthiness of the U.S. government and agency securities that we hold;

•increased concern over and scrutiny of capital and liquidity levels;

•increased cost of capital and labor;

•increased competition or consolidation in the financial services industry; and

•increased limitations on or potential additional regulation of financial service companies.

The U.S. economy and financial markets have experienced volatility in recent years and may continue to do so in the foreseeable future. Robust demand, labor shortages, supply chain constraints, structural and secular changes, and tariffs and other trade policies, as well as geographical tensions and other conditions, have led to persistent inflationary pressures throughout the economy. In response to these inflationary pressures, the Federal Reserve raised benchmark interest rates in the past, and may cause the Federal Reserve to raise interest rates again in response to economic conditions, particularly in a continued high rate of inflation. Amidst these uncertainties, financial markets have continued to experience volatility. If financial markets remain volatile or if the aforementioned conditions result in further economic stress or recession, the performance of various segments of our business, including the value of our investment securities portfolio, could be significantly impacted, with the significance of the impact generally depending on the nature and severity of the adverse economic conditions.

Although the rate of inflation fell in 2024 and 2025, after rising sharply in 2022 and 2023, certain policy changes or actions, such as increased tariffs, may increase the risk that inflation will rise again. Prolonged periods of inflation may further impact our profitability by negatively impacting our fixed costs and expenses, including increasing funding costs and expenses related to talent acquisition and retention. If significant inflation continues, our business could be negatively affected by, among other things, increased default rates leading to credit losses which could decrease our appetite for new credit extensions. In addition, a prolonged period of inflation could cause an increase in wages and other costs to the Company. These inflationary pressures could result in missed earnings and budgetary projections causing our stock price to suffer. We continue to closely monitor the pace of inflation and the impacts of inflation on the larger market, including labor and supply chain impacts.

Even when economic conditions are relatively good or stable, specific economic factors can negatively affect our business and performance. This can be especially true when the factors relate to particular segments of the economy and impact our customers whose operations or financial conditions are directly or indirectly dependent on good or stable conditions in those segments. For example, given the fundamental change in office demand driven by the acceptance of remote work, commercial real estate space remains underutilized. This, combined with higher interest rates, likely decreases demand for financial services in that sector and may make it more difficult for borrowers to refinance maturing loans, contributes to decreased property values and harms the creditworthiness of some of our office commercial real estate customers, as well as businesses whose customers have historically been office workers.

Our profitability depends significantly on local economic conditions in the states in which we conduct business.

The success of our business is dependent on the general economic conditions of the significant markets in which we operate, particularly Connecticut, Massachusetts, Rhode Island, New York, and New Jersey. Difficult economic conditions or adverse changes in such local markets, whether caused by inflation, recession, unemployment, changes in housing or securities markets, or other factors, could reduce demand for our loans and deposits, increase problem loans and charge-offs, affect the ability of borrowers to repay their loans, cause a decline in the value of collateral securing loans, and otherwise negatively affect our performance and financial condition. Any declines in real estate values in such local markets may adversely affect borrowers and the value of collateral securing many of our loans, which could adversely affect our current performing loans, leading to future delinquencies or defaults and an increase in our provision for credit losses.

Changes in interest rates and spreads, including the level and shape of the yield curve, may have a materially adverse effect on our business, financial condition, and results of operations.

Like other financial institutions, our business is sensitive to interest rate movements. Our financial condition and results of operations are significantly affected by changes in market interest rates. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions, the competitive environment within our markets, consumer preferences for specific loan and deposit products, and policies of various governmental and regulatory agencies, in particular the Federal Reserve. Changes in monetary policy, including changes in interest rates, could influence the amount of interest we receive on loans and securities, the amount of interest we pay on deposits and borrowings, our ability to originate loans and obtain deposits, and the fair market value of our financial assets and liabilities.

Increased interest rates may decrease demand for interest-rate based products and services, including loans and deposits; make it more difficult for borrowers to meet obligations under variable-rate or adjustable-rate loans and other debt instruments; increase our borrowing costs; and require us to increase the interest we pay on funds deposited with us; and reduce the market value of our securities holdings. Decreased interest rates often increase prepayments on loans and securities as borrowers refinance their loans to reduce borrowing costs. Under these circumstances, we are further subject to reinvestment risk to the extent that we cannot reinvest the cash received from such prepayments with interest rates comparable to pre-existing loans and securities. If the rate of economic growth decreased sharply, causing the Federal Reserve to lower interest rates, our net income could be adversely affected.

To the extent that interest rates increase, we expect competition for cost-effective deposits to also increase, making it more costly for the Bank to fund loan growth. Rapid and unexpected volatility in interest rates creates additional uncertainty and potential for adverse financial effects. There can be no assurance that the Bank will not be materially adversely affected by future changes in interest rates.

To a large degree, our consolidated earnings are dependent on net interest income, which is the difference between the interest income earned from our interest-earning assets and the interest expense paid on our interest-bearing liabilities. If the rates paid on interest-bearing liabilities increase at a faster rate than the yields received on interest-earning assets, our net interest income, and therefore earnings, could be adversely affected. Conversely, earnings could also be adversely affected if the yields received on interest-earning assets fall more quickly than the rates paid on interest-bearing liabilities. To the extent that the yield curve steepens, net interest income would benefit, primarily from the additional yield provided to fixed-rate asset reinvestment and production, without a commensurate offset from increasing funding costs. Conversely, a flatter yield curve would reduce net interest income, all else equal.

Although management believes that it has designed and implemented effective asset and liability management strategies to reduce the potential effects of changes in interest rates on our financial condition and results of operations, interest rates are affected by many factors outside of our control and any unexpected or prolonged period of interest rate changes could have a material adverse effect on our financial condition and results of operations. Further, our interest rate modeling techniques and assumption may not fully predict or capture the impact of actual interest rate changes on net interest income.

Changes in our financial condition or in the general banking industry, or changes in interest rates, could result in a loss of depositor confidence.

Liquidity is the ability to meet cash flow needs on a timely basis at a reasonable cost. The Bank uses its liquidity to extend credit and to repay liabilities as they become due or as demanded by customers. Our primary source of liquidity is our large supply of interest-bearing and non-interest bearing deposits. The continued availability of this supply of deposits depends on customer willingness to maintain deposit balances with banks in general and us in particular, as well as the continued inflow of deposits for new and existing customers. The availability of deposits can also be impacted by regulatory changes (e.g., changes in FDIC insurance, liquidity requirements, healthcare reform, legislation and regulation regulated to stablecoins, etc.), changes in financial condition of the Bank, other banks, or the banking industry in general, changes in the interest rates our competitors pay on their deposits, and other events which can impact the perceived safety or economic benefits of bank deposits. Many other financial institutions have increased their reliance on deposit funding and, as such, we expect continued competition in the deposit markets. We cannot predict how this competition will affect our costs. While we make significant efforts to consider and plan for hypothetical disruptions in our deposit funding, market-related, geopolitical, or other events could impact the liquidity derived from deposits.

Our stock price can be volatile.

Stock price volatility may make it more difficult for stockholders to resell their common stock when they want and at prices that they find attractive. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

•actual or anticipated variations in results of operations;

•recommendations or projections by securities analysts or failure to meet their expectations;

•operating and stock price performance of other companies that investors deem comparable to us;

•news reports relating to trends, concerns, and other issues in the financial services and healthcare industries;

24

Table of Contents

•perceptions in the marketplace regarding us and/or our competitors;

•new technology used, or services offered, by competitors;

•significant acquisitions or business combinations, strategic partnerships, joint ventures, or capital commitments by or involving us or our competitors;

•changes in dividends and capital returns;

•issuance of additional shares of Webster common stock;

•changes in government regulations; and

•geopolitical conditions such as acts or threats of terrorism or military conflicts, including the ongoing military conflict between Russia and Ukraine, or the conflicts in the Middle East.

General market fluctuations, including real or anticipated changes in the strength of the economy, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes, credit loss trends, among other factors, could also cause our stock price to decrease regardless of operating results.

The Company may not pay dividends to stockholders if it is not able to receive dividends from its subsidiary, the Bank.

The Company is a separate and distinct legal entity from the Bank and its non-banking subsidiaries. A substantial portion of the Company’s revenues are derived from dividends paid to it by the Bank. These dividends are the principal source of funds to pay dividends to common and preferred stockholders. Whether the Bank is able to pay dividends depends on its ability to generate sufficient net income and meet certain regulatory requirements, and the amount of such dividends may then be limited by federal laws. Any decision by the Company to return capital to stockholders requires the approval of the Company’s Board and must comply with applicable capital regulations, including the maintenance of capital ratios exceeding specified minimum levels and applicable buffers. In certain circumstances, we will not be able to make a capital distribution unless the Federal Reserve approves such distribution. As a bank holding company, we also are required to consult with the Federal Reserve before increasing dividends or redeeming or repurchasing capital instruments. Additionally, the Federal Reserve could prohibit or limit our payment of dividends if it determines that payment of the dividend would constitute an unsafe or unsound practice. In the event the Bank is unable to pay the Company dividends, we may not be able to pay dividends to our common and preferred stockholders.

Higher mortgage rates and low inventory adversely impact our ability to originate or refinance residential mortgage loans.

The residential mortgage lending business is sensitive to changes in interest rates, especially long-term interest rates. Lower interest rates generally increase the volume of mortgage originations and refinancing, while higher interest rates generally cause that volume to decrease. Therefore, our residential mortgage performance is typically correlated to fluctuations in interest rates. The sustained higher rates experienced between 2022 and into 2025, have negatively impacted the mortgage market, including our loan origination volume and refinancing activity. Although interest rates declined in 2024 and 2025, it is uncertain if and when they will decline further, which will ultimately be driven by monetary policy decisions by the Federal Reserve informed by inflation, labor market performance, and economic growth. Adverse market conditions, including increased volatility, changes in interest rates and mortgage spreads, and reduced market demand could result in greater risk in retaining mortgage loans. A reduction in our residential mortgage origination and refinancing volume could have a materially adverse effect on our financial condition and results of operations.

Risks Related to Operations

We rely on third parties to perform significant operational services for us.

Third parties perform significant operational services on our behalf. For instance, we depend on our vendor-provided core banking processing systems to process a large number of increasingly complex transactions on a daily basis. Accordingly, we are exposed to the risk that vendors and third-party service providers might not perform in accordance with their contracts or service agreements, whether due to changes in their organizational structure, strategic focus, support for existing products, technology, services, financial condition, or for any other reason. Their failure to perform could be disruptive to our operations, which could have a materially adverse impact on our business, results of operations, and financial condition. Although we require third-party service providers to have business continuity and disaster recovery plans that are aligned with our plans, such plans may not operate successfully or in a timely manner so as to prevent any such material adverse impact.

Our business may be adversely affected by fraud.

As a financial institution, we are inherently exposed to risk in the form of theft and other fraudulent activities by employees, customers, or other third parties targeting Webster or Webster’s customers or data. Such activity may take many forms, including check fraud, electronic fraud, wire fraud, phishing, social engineering, and other dishonest acts. Although we devote substantial resources to maintaining effective policies and internal controls to identify and prevent such incidents, given the increasing sophistication of possible perpetrators, we may experience financial losses or reputational harm as a result of fraud, including from risks that we have not appropriately anticipated, monitored, or identified.

25

Table of Contents

Our internal controls may be ineffective, circumvented, or fail.

Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls and procedures, failure to implement any necessary improvement of controls and procedures, or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations, and financial condition.

Climate change manifesting as physical or transition risks could adversely affect our operations, businesses, and customers.

There is an increasing concern over the risks of climate change and related environmental sustainability matters. The physical risks of climate change include discrete events, such as flooding, wildfires, and other climate-related events, and longer-term shifts in climate patterns, such as extreme heat, sea level rise, and more frequent and prolonged drought. Such events could disrupt our operations, those of our customers, or third parties on which we rely, including through direct damage to assets, such as those securing certain loans, and indirect impacts from supply chain disruption and market volatility. In addition, transitioning to a low-carbon economy may entail extensive policy, legal, technological, and market initiatives. Transition risks, including changes in consumer preferences and additional regulatory requirements or taxes, could increase our expenses and undermine our strategies.

Further, due to divergent policies and viewpoints regarding climate change, we are at increased risk of being subject to different and potentially conflicting legal or regulatory requirements and stakeholder expectations. Furthermore, ongoing legislative or regulatory uncertainties and changes regarding climate-related matters may result in higher regulatory, compliance, credit, and other risks and costs.

We are exposed to environmental liability risk with respect to properties to which we obtain title.

A significant portion of our loan portfolio is secured by real property. In the normal course of business, we may foreclose on and take title of properties securing certain loans, and there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, we may be held liable for remediation costs, including significant investigation and clean-up costs and for personal injury or property damage. In addition, environmental contamination could materially reduce the affected property’s value or limit our ability to use or sell the affected property. Although we have policies and procedures to perform environmental reviews prior to lending against or initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. Further, if we are the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs incurred by others due to environmental contamination emanating from the property. These remediation costs and liabilities could have a material adverse effect on our business, financial condition, and results of operations.

There may be risks resulting from the extensive use of models in our business.

We rely on financial and economic models to measure risks, estimate certain financial values, and inform certain business decisions. Models may be used in processes such as risk management, asset management, valuation, capital and reserve calculations, and financial reporting. Models generally predict or infer certain financial outcomes, leveraging historical data and assumptions as to the future, often with respect to macroeconomic conditions. Development and implementation of some of these models requires us (or third parties) to make difficult, subjective, and complex judgments. Such judgments may not capture or fully incorporate conditions leading to losses, particularly in times of market distress, and the historical correlations on which we rely may no longer be relevant. Additionally, as businesses and markets evolve, the data and assumptions used in these models may not accurately reflect this evolution. If the design, implementation, or incorrect use of our models (or our third parties’ models) is flawed, or a model’s assumptions or limitations are misunderstood or set incorrectly, we could make business, strategic, or tactical decisions based on a model’s output that is incorrect, misleading, or incomplete. Further, to the extent that we incorporate AI as part of our modeling process, this may lead to heightened risk. For example, AI has been known to produce false or “hallucinatory” inferences or output, and certain AI uses machine learning and predictive analytics, which can create inaccurate, incomplete, or misleading output, unexpected results, errors, or inadequacies, any of which may not be easily detectable. In addition, information we provide to the public or to our regulators based on poorly designed, implemented, or incorrectly used models could be misleading or inaccurate. Certain decisions that the regulators make, including those related to requests we may make to pay dividends to our stockholders, could be adversely affected due to a regulator’s negative perception of our risk or business management, including but not limited to, insufficient model quality or incorrect model use.

The development and use of AI, including by third parties, presents risks and challenges that may adversely impact our business.

We are in the early stages of incorporating AI into our business activities to increase employee productivity. We have not yet deployed AI-driven systems in critical decision-making or client-facing processes. Our vendors or third parties may develop or incorporate AI technology in certain business processes, services, or products. Any reliance on AI presents a number of risks

26

Table of Contents

and challenges to our business. The legal and regulatory environment relating to AI is uncertain and rapidly evolving, both in the U.S. and internationally, and includes regulatory schemes targeted specifically at AI. During 2025, President Trump issued a number of Executive Orders aimed at reducing barriers to AI innovation in the U.S. economy and establishing a federal framework with a national standard. The Executive Order issued on January 23, 2025, requires relevant persons and bodies within the federal government to develop an AI action plan to carry out this objective and revokes prior AI-related Executive Orders, as well as all corresponding policies, regulations, order, directives, and other actions taken in response to such Executive Order. These evolving laws and regulations could require changes in our consideration and implementation of AI technology and increase our compliance costs and the risk of non-compliance.

AI models, including generative AI models, may produce output or influence us or third-party service providers to take actions that are incorrect, that result in the release of private, confidential, or proprietary information, that may reflect biases included in the data on which they are trained, that could result in the release of confidential company information, infringe on intellectual property rights, or that is otherwise harmful. Further, the complexity of many AI models makes it challenging to understand why they are generating particular outputs. This limited transparency increases the challenges associated with assessing the proper operation of AI models, understanding and monitoring the capabilities of the AI models, reducing erroneous output, eliminating bias, and complying with regulations that require documentation or explanation of the basis on which decisions are made. Thus, the use of an AI model and the risks related to it could expose us to liability or adverse legal or regulatory consequences and harm our reputation and the public perception of our business or the effectiveness of our security measures.

In addition to our use of AI technologies, we are exposed to risks arising from the use of AI technologies by bad actors to commit fraud and misappropriate funds. and to facilitate cyber-attacks. Use of AI technologies by bad actors can contribute to the evolution of new and more effective techniques, which can hinder our efforts to prevent, detect, and remediate such harmful activities. AI, if used to perpetrate fraud or launch cyber-attacks, could result in losses, liquidity outflows, or other adverse effects at a particular exchange or financial institution, including us.

A failure or breach of our information systems, including as a result of cyber-attacks, could disrupt our businesses, result in the misuse of confidential or proprietary information, damage our reputation, and cause losses.

As a financial institution, we depend on our ability to process, record, and monitor a large number of customer transactions. Accordingly, our operational systems and technology infrastructure must continue to be safeguarded and monitored for potential failures, disruptions, and breakdowns. Our business, financial, accounting, data processing, or other operating systems and facilities, including mobile banking applications and other recently developed technologies, may stop operating properly or become disabled or compromised as a result of a number of factors that may be beyond our control. For example, there could be sudden increases in customer transaction volume, electrical or telecommunications outages, natural disasters, pandemics, events arising from political or social matters, including terrorist acts and cyber-attacks, all of which may contribute to a cybersecurity threat.

Although we have business continuity plans and information security and technology processes and controls in place, we are at risk of cybersecurity threats due to disruptions or failures in the operational systems or technology infrastructures that support our businesses and customers, or cyber-attacks or security breaches of the networks, systems, or devices on which information assets are stored or are used by customers to access our products and services. Any of these incidents could result in customer attrition, regulatory fines, penalties or intervention, reputational damage, reimbursement, or other compensation costs, which could have a material adverse effect on our business strategy, results of operations, or financial condition.

Additionally, third parties with whom we do business or that facilitate our business activities, including exchanges, clearing houses, financial intermediaries, or vendors that provide services or security solutions for our operations, could also be sources of operational risk and information security risk, including breakdowns or failures of their own systems, capacity constraints, and cyber-attacks, each of which could pose a cybersecurity risk.

In recent years, information security risks for financial institutions have risen due to the increased sophistication and activities of organized crime, hackers, terrorists, hostile foreign governments, activists, and other external parties. There have been instances involving financial services and consumer-based companies reporting unauthorized access to, and disclosure of, customer information or the destruction or theft of corporate data. There have also been highly publicized cases where hackers have requested ransom-payments in exchange for allowing access to systems and/or not disclosing customer information. Security breaches affecting our customers, or system breakdowns, failures, security breaches, or employee misconduct affecting such other third parties, may require us to take steps to protect the integrity of our own systems or to safeguard our confidential information or of our customers, thereby increasing our operational costs and adversely affecting our business. Additionally, successful cyber-attacks at other large financial institutions, whether or not we are impacted, could lead to a general loss of customer confidence in financial institutions that could negatively affect us, including harming the market perception of the effectiveness of our security measures or the financial system in general, which could result in reduced use of our financial products.

Our inherent risk and exposure to information security matters remains heightened, and as a result, the continued development and enhancement of our controls, processes, and practices designed to protect operational systems, computers, software, data, and networks from attack, damage, or unauthorized access remains a high priority for us. While we have purchased network and privacy liability insurance coverage, which includes digital asset loss, business interruption loss, network security liability, privacy liability, network extortion, and data breach coverage, such insurance may not cover any and all actual losses. As cybersecurity threats and related regulations continue to evolve, we may be required to expend significant additional resources to modify our protective measures or to investigate and remediate any information security vulnerabilities.

We may not be able to successfully implement current or future information technology system enhancements and operational initiatives, which could adversely affect our business operations and profitability.

We continue to invest significant resources in our core information technology systems in order to provide functionality and security at an appropriate level, and to improve our operating efficiency and to streamline our client experience. These initiatives significantly increase the complexity of our relationships with third-party service providers and such relationships may be difficult to unwind. We may not be able to successfully implement and integrate such system enhancements and initiatives, which could adversely impact our ability to comply with certain legal and regulatory requirements. In addition, these projects could have higher than expected costs and/or result in operating inefficiencies, which could increase the costs associated with the implementation as well as ongoing operations. Failure to properly utilize system enhancements that are implemented in the future could result in impairment charges that adversely impact our financial condition and results of operations, could result in significant costs to remediate or replace the defective components, and could impact our ability to compete. In addition, we may incur significant training, licensing, maintenance, consulting, and amortization expense during and after implementation, and any such costs may continue for an extended period of time. As such, we cannot guarantee anticipated long-term benefits from these system enhancements and operational initiatives.

Changes in our accounting policies or in accounting standards could materially impact how we report our financial results.

Our accounting policies and methods are fundamental to understanding how we record and report our results of operations and financial condition. Accordingly, we exercise judgment in selecting and applying these accounting policies and methods so they comply with GAAP. The FASB, SEC, and other regulatory bodies that establish accounting standards periodically change the financial accounting and reporting standards, or the interpretation of those standards, that govern the preparation of our financial statements. These changes are beyond our control, can be hard to predict, and could materially impact how we report our results of operations and financial condition. We could be required to apply a new or revised standard retrospectively, which may result in us having to restate our prior period financial statements by material amounts.

The preparation of our consolidated financial statements requires the use of estimates that may vary from actual results.

The preparation of the Company’s Consolidated Financial Statements, and the accompanying Notes thereto, in conformity with GAAP requires management to make difficult, subjective, or complex judgments about matters that are uncertain, which include assumptions and estimates of current risks and future trends, all of which may undergo material changes. Materially different amounts could be reported under different conditions or using different assumptions and estimates. Because of the inherent uncertainty of estimates involved in preparing our financial statements, we may be required to significantly adjust the financial statements as actual events unfold, which could have a material adverse effect on our financial condition and results of operations. Significant estimates subject to change include, among other items, the allowance for credit losses, the carrying value of goodwill or other intangible assets, the fair value estimates of certain assets and liabilities, and the realization of deferred tax assets and liabilities.

A significant merger or acquisition requires us to make estimates, including the fair values of assets acquired and liabilities assumed.

GAAP requires us to record the assets and liabilities of an acquired business to their fair values at the time of the acquisition. With larger transactions, fair value and other estimations can take up to four quarters to finalize. These estimates, and their revisions, can have a substantial effect on the presentation of our financial condition and operating results after the Transaction closes. In addition, the excess of the purchase price over the fair value of the assets acquired, net of liabilities assumed, is recorded as goodwill. If the estimates that we have used at any financial statement date are significantly revised in the future, there could be a material negative impact on our goodwill or other acquisition-related intangibles and our results of operations for the period in which the revisions are made.

If our goodwill were determined to be impaired, it could have a negative impact on our profitability.

GAAP requires that goodwill be tested for impairment at the reporting unit level on at least an annual basis or more frequently upon the occurrence of a triggering event. An impairment loss is to be recognized if the carrying value of the net assets assigned to the reporting unit exceeds the fair value of the reporting unit. A significant decline in our expected future cash flows, a continued period of local and national economic disruption, changes to financial markets, slower growth rates, or other external factors, all of which can be highly unpredictable, may impact fair value calculations and require us to recognize an impairment

loss in the future. Such an impairment loss may be significant and have a material adverse effect on our financial condition and results of operations.

Risks Related to Compliance

We face risks related to the adoption of future legislation and potential changes in federal regulatory agency leadership, policies, and priorities.

Changes in key personnel at the regulatory agencies, including the federal banking regulators, may result in differing interpretations of rules and guidelines, including more stringent enforcement and more severe penalties than previously. Disagreements between, or in, the U.S. Congress on the federal budget and debt ceiling may lead to total or partial government shutdowns, which can create economic instability and negatively affect our business and financial performance. New federal or state laws and regulations regarding lending and funding practices and liquidity standards could negatively impact the Bank’s business operations, increase the cost of compliance, and adversely affect profitability. The failure of banks to follow existing laws and regulations contributes to bank failures, which also adversely affects the banking industry and can lead to special FDIC assessments, such as what we are currently subject to.

Changes in federal, state, or local tax laws may negatively impact our financial performance.

We are subject to changes in tax laws that could increase our effective tax rates or cause an increase or decrease in our income tax liabilities. These law changes may be retroactive to previous periods and as a result, could negatively impact our current and future financial performance.

We are subject to extensive government regulation and supervision, which may interfere with our ability to conduct our business operations.

We are subject to extensive federal and applicable state regulation and supervision, primarily through the Bank and certain non-bank subsidiaries. Banking regulations are primarily intended to protect depositors, the DIF, and the safety and soundness of the U.S. banking system as a whole, not stockholders. These regulations affect our lending practices, capital structure, investment practices, dividend policy, and growth, among other things. Congress and federal bank regulatory agencies continuously review banking laws, regulations, and policies for possible changes, and proposed changes are to be expected. It is not possible to predict the nature of future changes to statutes, regulations, or regulatory policies, including changes in interpretation or implementation thereof, which could affect us in substantial and unpredictable ways. Changes in the U.S. presidential administration and Congress have led and will likely continue to lead to changes in law or policy. In addition, changes in key personnel at the agencies that regulate us, including the federal bank regulatory agencies, may result in differing interpretations of and focus on existing rules and guidelines. Although the Trump Administration has indicated an intent to pursue the regulation of the financial services industry differently than was the case under the previous administration, there is significant uncertainty regarding the direction this administration will continue to take and its ability to implement its policies and objectives, as well as the ultimate impact on potential new regulatory initiatives and the enforcement of existing laws and regulations. It is possible the expected changes in regulation do not occur or are reversed by a subsequent administration, or the regulatory measures that are ultimately enacted deliver significant competitive advantages to financial services providers that are structured differently or serve different markets than we do. Such changes could subject us to additional costs, limit the types of financial services and products we may offer, and affect what we are able to charge for certain banking services, or lead to regulatory uncertainty. Failure to comply with laws, regulations, or policies could result in sanctions by regulatory agencies, civil penalties, and reputation damage, which could have a material adverse effect on our business, financial condition, and results of operations. While we have policies and procedures designed to prevent these types of violations, there can be no assurance that such violations will not occur.

Significant changes to the size and operations of the federal government agencies may cause economic disruptions that could adversely impact our business, results of operations and financial condition.

The Trump Administration is implementing significant changes to the size of the federal government. To date, there have been executive actions to eliminate or modify federal agency and federal program funding, reduce the size of the federal workforce and minimize the oversight of certain federal agencies, and encourage the use of AI and other advanced technologies. Government services and federal program funds and benefits have been and may continue to be disrupted or eliminated which could adversely affect regional and local economies and our customers, and thus our business, results of operations and financial condition. If there is an absence of, or significant decrease in, comprehensive federal regulation and oversight, we could become increasingly burdened by a patchwork of overlapping by differing state and local laws, rules, and regulations, which would increase uncertainty with respect to certain matters and require us to incur additional costs and expenses in an effort to comply.

Regulatory compliance expense may increase substantially when we reach $100 billion in assets, which is the next regulatory tier above us now. Moreover, we expect such costs to increase significantly as we approach that size.

Regulatory restrictions and costs tend to increase based on a bank holding company’s and bank’s consolidated asset tiers. Becoming subject to Category IV enhanced prudential standards will have the most significant impact on us after we cross the $100 billion in total consolidated assets threshold. As of December 31, 2025, we had more than $84 billion in assets on a consolidated basis. Under such enhanced prudential standards, Category IV bank holding companies are subject to greater regulation and supervision, including, but not limited to: certain capital planning and stress testing and capital buffer requirements; supervisory capital stress testing conducted by the Federal Reserve biennially; and certain liquidity risk management and liquidity stress testing and buffer requirements. Our preparations for, and the application of, these enhanced prudential standards and resolution planning requirements for our depository institution could adversely affect our results of operations and financial performance through additional capital and liquidity requirements and increased compliance costs. Compliance costs associated with those and other Category IV regulations have historically been significant. Moreover, we expect that a significant portion of those compliance costs to be incurred as we approach the $100 billion tier, rather than commence abruptly when we become a Category IV bank, as we upgrade compliance systems, processes, and staffing before they are fully needed.

We are subject to examinations and challenges by taxing authorities.

We are subject to federal and applicable state and local income tax regulations. Income tax regulations are often complex and require interpretation. In the normal course of business, we are routinely subject to examinations and challenges from federal and applicable state and local taxing authorities regarding the amount of taxes due in connection with investments we have made and the businesses in which we have engaged. Recently, federal and state and local taxing authorities have been increasingly aggressive in challenging tax positions taken by financial institutions. These tax positions may relate to compliance, sales and use, franchise, gross receipts, payroll, property, and income tax issues such as tax base, apportionment, and tax credit planning. The challenges made by taxing authorities may result in adjustments to the timing or amount of taxable income or deductions, or the allocation of income among tax jurisdictions. If any such challenges are made and are not resolved in our favor, they could have a material adverse effect on our financial condition and results of operations.

Health care reform could adversely affect our Healthcare Financial Services segment.

The enactment of future health care reform affecting HSAs and/or workers compensation at the federal or state level may affect our Healthcare Financial Services segment as a bank custodian of HSAs and insurance claim settlements. We cannot predict if any such reforms will occur, ultimately become law, or if enacted, what the terms or regulations promulgated pursuant to such laws will be. Any health care reform enacted may be phased in over a number of years, but could, with respect to the operations of our Healthcare Financial Services segment, reduce revenues, increase costs, and require us to revise the ways in which we conduct business or put us at risk for loss of business. In addition, our results of operations, financial position, and cash flows could be materially adversely affected by such changes.

We are subject to financial and reputational risks from potential liability arising from lawsuits.

The nature of our business ordinarily results in certain legal proceedings and claims. Whether claims or legal actions are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to us, they may result in significant financial liability and/or adversely affect how the market perceives us, the products and services we offer, as well as customer demand for those products and services. Any financial liability or reputation damage could have a material adverse effect on our business, which could have a material adverse effect on our financial condition and results of operations.

We assess our liabilities and contingencies in connection with outstanding legal proceedings and certain threatened claims and assessments using the latest and most reliable information. For matters identified where it is probable that we will incur a loss and we can reasonably estimate the amount, we will establish an accrual for the loss. Once established, the accrual is then adjusted, as needed, to reflect any relevant developments. However, the actual cost of an outstanding legal proceeding or threatened claim and assessment may be substantially higher than the amount accrued by management.

We are subject to complex state and federal laws and regulations regarding data privacy and security, which impact how we conduct our business.

We are subject to complex and evolving data privacy laws, rules and contractual obligations (collectively “data privacy laws”) that relate to the privacy and security of the personal information of our customers and employees, or any other natural persons. These data privacy laws require, among other things, that we make certain privacy disclosures, maintain a robust security program, require disclosures and notifications during a cyber or information security incident, and regulate our collection, use, sharing, retention, and safeguarding of consumer or employee information. State and federal regulators may also hold us responsible for privacy and data protection obligations performed by our third-party service providers while providing services to us, as well as disclosures and notifications during a cyber or information security incident. Consumers also have the option to direct us and other financial institutions not to share information about transactions and experiences with affiliated companies for the purpose of marketing products or services.

30

Table of Contents

State regulators have also been increasingly active in implementing privacy and cybersecurity regulations. Several states have also recently strengthened their data breach notification and data privacy requirements. We expect this trend of state-level activity in those areas to continue and are continually monitoring developments, particularly if the CFPB is no longer actively enforcing federal financial institution consumer privacy laws and regulations. As the regulatory environment becomes more rigorous, we anticipate that compliance with these requirements will result in additional costs and expenses, and may impact the way we conduct business. Our failure to comply with data privacy laws could result in potentially significant regulatory or governmental investigations, litigation, fines, or sanctions, or cause damage to our reputation, which could have a material adverse effect on our business, financial condition, or results of operations.

Risks Related to Strategy

New lines of business or new products and services may subject us to additional risk.

On occasion, we may implement new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where markets are not fully developed. In developing and marketing new lines of business and/or new products and services, we may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved, and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives, and shifting market preferences may also impact the successful implementation of a new line of business and/or a new product or service. Further, any new line of business and/or new product or service could have a significant impact on the effectiveness of our system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business and/or new products or services could have a material adverse effect on our business, results of operations, and financial condition.

We may not be able to attract and retain skilled people, and the loss of key employees or the inability to maintain appropriate staffing may disrupt relationships with customers and adversely impact our business.

Our success depends, in large part, on our ability to attract, develop, compensate, motivate, and retain skilled people, including executives, managers, and other key employees with the skills and know-how necessary to run our business. The failure to attract or retain talented executives, managers, and employees with diverse backgrounds and experiences, or the loss of certain executives, managers, and key employees, could have a material adverse impact on our business. These risks may be heightened when U.S. labor markets, or segments of those markets, are especially competitive.

Competition for the best people in most activities in which we engage can be intense, and we may not be able to hire sufficiently skilled people or retain them. The recent transition towards companies offering remote and hybrid work environments, which is expected to endure, as well as our workplace policies (or perceptions of those policies by current and potential employees), including policies with respect to remote and hybrid work, could impact our ability to attract and retain talent with the necessary skills and experience. In addition, the transition to remote and hybrid work environments may exacerbate the challenges of attracting and retaining skilled employees because job markets may be less constrained by physical geography. Our current or future approach to in-office and remote-work arrangements may not meet the needs or expectations of our current or prospective employees or may not be perceived as favorable as the arrangements offered by other employers, which could adversely affect our ability to attract and retain employees. The unexpected loss of services of our key personnel could have a material adverse impact on the business because of their skills, knowledge of our markets, years of industry experience, and the difficulty of promptly finding qualified replacement personnel.

Further, our business is primarily relationship-driven, in that many of our key employees have extensive customer relationships. The loss of a key employee with such customer relationships may lead to the loss of business if the customers were to follow that employee to a competitor or otherwise choose to transition to another financial services provider. While we believe that our relationships with key personnel are good, we cannot guarantee that all of our key personnel will remain with our organization.

We operate in a highly competitive industry and market area.

We face substantial competition in all areas of our operations from a variety of different competitors, both within and beyond our financial markets, many of which are larger and may have more financial resources than we do. Such traditional competitors primarily include national, regional, community, and internet banks within the various markets in which we operate, including the HSA market. We also face competition from many other types of financial institutions, including savings and loans, credit unions, non-bank health savings account trustees, finance companies, brokerage firms, insurance companies, online lenders, factoring companies, and other financial intermediaries. Some of these organizations are not subject to the same degree of regulation that is imposed on bank holding companies and federally insured depository institutions, which may give them greater flexibility in accessing funding and providing various services. Moreover, organizations that are larger than we are may be able to achieve greater economies of scale or offer a broader range of products and services, or better pricing on products and services, than what we can offer.

The financial services industry could become even more competitive as a result of legislative and regulatory changes, and continued consolidation. This consolidation may produce larger, better capitalized, and more geographically diverse companies that are capable of offering a wider array of financial products and services at more competitive prices. In addition, as customer preferences and expectations continue to evolve, technology has lowered barriers to entry and has made it possible for non-banks to offer products and services traditionally provided by banks. The financial services industry also faces increasing competitive pressure from the introduction of disruptive new technologies, such as blockchain and digital payments, often by non-traditional competitors and financial technology companies. In particular, the activity of financial technology companies has grown significantly over recent years and is expected to continue to grow. Among other things, technology and other changes are allowing customers to complete financial transactions that historically have involved banks at one or both ends of the transaction. The move toward digital banking and financial services, and customer expectations regarding digital offerings, will require us to invest greater resources in technological improvements and may put us at a disadvantage to banks and non-banks with greater resources to spend on technology.

Our ability to compete successfully depends on a number of factors, including, among other things:

•the ability to develop, maintain, and build upon long-term customer relationships based on top quality service, high ethical standards, and safe, sound financial position;

•the ability to expand our market position;

•the scope, relevance, and pricing of products and services offered to meet customer needs and demands, including within the HSA market;

•the rate at which we introduce new products and services relative to our competitors;

•customer satisfaction with our level of service and products;

•the quality of the technology that supports the customer experience; and

•industry and general economic trends.

Failure to perform in any of these areas could significantly weaken our competitive position, which could adversely affect our growth and profitability, and in turn, could have a material adverse effect on our financial condition and results of operations.

Failure to keep pace with and adapt to technological change could adversely impact our business.

The financial services industry is continually undergoing rapid technological change with frequent introductions of new technology-driven products and services and the use of artificial intelligence. These new technologies may be superior to, or render obsolete, the technologies currently used in our products and services. Our future success depends, in part, upon our ability to address the needs of our customers by using technology and information to provide products and services that will satisfy customer demands, as well as to create additional efficiencies in our operations. Many of our competitors have substantially greater resources to invest in technological improvements because of their larger size and available capital. Developing or acquiring new technologies and incorporating them into our products and services may require significant investment, take considerable time, and ultimately may not be successful. We cannot predict which technological developments or innovations will become widely adopted or how those technologies may be regulated. We also may not be able to effectively market new technology-driven products and services to our customers. Failure to successfully keep pace with and adapt to technological change affecting the financial services industry could have a material adverse impact on our business and, in turn, our financial condition and results of operations.

The loss of key partnerships could adversely affect our Healthcare Financial Services segment and interSYNC operations.

Our Healthcare Financial Services segment and interSYNC operations rely on partnerships to maximize our distribution model. To the extent that we fail to maintain such partnerships, which may be due to mergers and/or acquisitions and may result in changes to their business processes, or our partners choosing to align with competitors or develop their own solutions, our business, financial condition, and results of operations could be adversely affected. In particular, health plan partners who provide high deductible health plan options are a significant source of new and existing HSA holders. If these health plan partners or other partners choose to align with our competitors or develop their own solutions, our business, financial condition, and results of operations could be adversely affected.

There is significant competition for our existing partners, and our failure to retain our existing larger partner relationships upon expiration or the earlier loss of a relationship upon the exercise of a partner’s early termination rights, or the expiration or termination of a substantial number of small partner relationships, could have a material adverse effect on our results of operations (including growth rates) and financial condition to the extent that we do not acquire new partners of similar size and profitability or otherwise grow our business. In addition, existing relationships may be renewed with less favorable terms to the Company in response to increased competition for such relationships. The competition for new partners is also significant, and our failure to attract new partners could adversely affect our ability to grow.

Our investments in certain tax-advantaged projects may not generate returns as anticipated, or at all, and may have an adverse impact on our results of operations.

We invest in certain tax-advantaged investments that support qualified affordable housing projects and other community development initiatives. Our investments in these projects rely on the ability of the projects to generate a return primarily through the realization of federal and state income tax credits and other tax benefits. We face the risk that tax credits, which remain subject to recapture by taxing authorities based on compliance with relevant requirements at the project level, may not be able to be realized. The risk of not being able to realize the tax credits and other tax benefits associated with a particular project depends on many factors that are outside of our control. A project’s failure to realize these tax credits and other tax benefits may have a negative impact on our investment, and as a result, on our financial condition and results of operations.

Increasing scrutiny and evolving expectations from customers, regulators, investors, and other stakeholders with respect to our corporate responsibility practices may impose additional costs on us or expose us to new or additional risks.

Companies are facing increasing scrutiny from customers, regulators, investors, and other stakeholders related to their corporate responsibility practices and disclosure. Investor advocacy groups, investment funds, and influential investors are also increasingly focused on these practices, especially as they relate to the environment (including with respect to climate change), health and safety, inclusion and belonging, human capital management, labor conditions, and human rights. Due to divergent stakeholder views, priorities and expectations on these matters, we are at increased risk that any action, or lack thereof, concerning these matters will be perceived negatively by some stakeholders. Failing to comply with expectations and standards, or taking action in conflict with one or multiple of those stakeholders’ expectations, could also lead to loss of business, impacts on our talent management strategy, adverse publicity, and adverse impact on our business and reputation, customer complaints, or public protests. Furthermore, as a result of our diverse base of clients and business partners, we may face potential negative publicity based on the identity of our clients or business partners and the public’s (or certain segments of the public’s) view of those entities. Increased corporate responsibility-related compliance costs for us, as well as among our third-party suppliers, vendors, and various other parties within our supply chain, could also result in increases to our overall operational costs. Any success, failure, or perceived success or failure (whether or not valid) to pursue or fulfill corporate responsibility-related objectives, comply with evolving regulatory requirements, or meet investor or stakeholder expectations and standards could negatively impact our reputation, ability to do business with certain partners, access to capital, and the price of our stock. There can be no assurance that we will achieve these corporate responsibility-related objectives or that any such achievements will have the desired results.

Our reputation and client relationships may be damaged as a result of our practices related to climate change.

Our reputation and client relationships may be damaged as a result of our practices related to climate change, including our direct or indirect involvement in certain industries or projects associated with causing or exacerbating climate change, as well as any decisions we make to conduct or change our activities in response to managing climate risk. While we have relatively limited exposure to climate risks in our operations and lending portfolio, we consider climate-related risks in our business operations and in our lending activities. We have developed and continue to enhance processes to assess, monitor, and mitigate the Bank’s exposure to climate risk. However, because the timing and impact of climate change have limited predictability, our risk management strategies may not be effective in mitigating climate risk exposure.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy. The Company has processes for assessing, identifying, and managing material risks from cybersecurity threats, and is committed to the prevention, detection, and timely response to cybersecurity threats that may impact the confidentiality, integrity, and availability of its information systems and information assets.

The Company has a Technology Risk Management Program (First Line), including Cyber and Information Risk Management, a First Line Control Office, and an Information Risk Management Program (Second Line) under its Risk Governance Framework for the identification, assessment, measurement, mitigation, monitoring, and internal reporting of risks associated with its information systems, information assets, and third parties, including vendors and service providers. The Cyber and Information Security Risk Management Program and Technology Risk Management Program align with the Company’s Third-Party Risk Management Program in regard to protecting information assets. Internal Audit (Third Line) also performs periodic audits of these risk management programs in accordance with their internal audit plan, which is approved by the Audit Committee of the Board.

The Cyber and Information Security Risk Management Program and Technology Risk Management Program are managed by the Company’s Corporate Information Security team, led by the CISO and the CIO. Our CISO has over 25 years of financial services industry experience, with varying positions in information technology, security, and risk management. She has numerous industry certifications, including Certified Information Systems Security Professional and Certified in Risk and Information Systems Controls certifications. She is a board of directors member with the Cyber Risk Institute, and a member of ISACA’s global Emerging Trends Working Group and Securing AI Certification Working Group. Our CIO has over 25 years of relevant experience in large scale digital transformation, strategic planning, talent development, global technology delivery, and operational experience. Our CIO has deep expertise across the financial services industry and in leading organizations through change. He is a member of the CNBC Technology Executive Council, where he contributes to ongoing discussions and insights on the latest trends and challenges in technology. In addition, he is a member of the Wall Street Journal CIO Network, a collective community of leading technology experts from the world’s most influential companies. Both our CISO and CIO also participate in various financial services industry committees and cybersecurity advisory boards.

On average, the other Corporate Information Security team members have over a decade of cybersecurity experience and hold over 100 industry-leading certifications in cybersecurity. For most of these certifications, there is a continuing professional education requirement to maintain a consistent level of learning by completing certain professional activities, such as attending conferences and workshops, completing online training courses, and participating in professional association meetings, throughout the certification cycle to maintain an active credential. Further, each employee is responsible for an effective cybersecurity defense which is enforced with mandatory cyber awareness training, periodic newsletters, and security updates.

“Zero trust principles” drive the Company’s information security architecture, and the Company deploys a “defense in-depth” strategy to protect against cybersecurity threats, layering multiple levels of information security and technology controls within business processes for information assets and relationships with third parties based on the National Institute of Standards and Technology Special Publication 800-53 Framework. The Company’s information systems and risk management are also subject to regulatory requirements and examination by federal banking regulators.

The identification of control weaknesses and vulnerabilities affecting information assets and/or relationships with third parties allows the Company to mitigate risk from, and respond to, cybersecurity threats. Initial risk assessments are performed upon the acquisition, or as part of the development of, information assets in order to evaluate the inherent risk associated with network and host environments and assess the adequacy of implemented technology operation processes and controls. Risk and control self-assessments are conducted on an annual basis to identify gaps resulting from any process changes that occurred during the year, and to evaluate whether the levels of cybersecurity risk remain within the tolerance set in the Company’s Risk Appetite Statement or whether a risk needs to be mitigated.

Due diligence is performed prior to onboarding all third parties with access to the Company’s information assets to ensure such parties maintain security controls contractually required by the Company as part of its Third Party Risk Management Program. The Company provides ongoing monitoring, including cybersecurity maturity assessments, of third parties using a risk-based approach to determine the extent and frequency of periodic assessments. Semi-annual cybersecurity maturity assessments are conducted by the Company’s Corporate Information Security team on its information systems using industry-standard guidelines and tools, including the National Institute of Standards Cybersecurity Framework, the Federal Financial Institutions Examination Council Cybersecurity Assessment Tool, and the Center for Internet Security Critical Security Controls.

Table of Contents

Because cybersecurity threats continue to evolve, thereby increasing inherent risk, the Company’s Corporate Information Security team is augmented by contracted external managed security service providers, who collectively work 24/7 to monitor cybersecurity threats through processes such as endpoint and network security, email protection, data loss prevention, vulnerability scanning and mitigation, identity and access management, logging and monitoring, and threat hunting. Independent third parties test the Company’s cyber capabilities and audit its cloud security. The Company regularly tests its systems to discover and address any potential vulnerabilities. Senior and Executive management also participate in cybersecurity industry collaboration and information-sharing forums and utilize the information gained to drive protective and detective cybersecurity strategies and tactics.

The Company requires information security education, training at the time of hire, and annually thereafter, by its employees (including contractors and other third parties for training purposes), designed to mitigate accidental information security incidents. Phishing simulation activities are regularly conducted to assess employees’ competency at identifying potential threats. Employees are assigned incremental training requirements should they fail to identify simulated phishing emails through the initial training.

The Company’s Corporate Information Security team members are also responsible for completing additional mandatory annual training to understand the processes, procedures, and technical requirements for securing information assets across the enterprise. The Company also offers ongoing practice and specialized education for Corporate Information Security team members to stay up to date with emerging trends in cybersecurity threat protection, detection, and response.

The Information Security Management Program sets forth enterprise-wide coordinated responses to identified threats, ensuring timely mitigation and remediation, and facilitating awareness and communication. Tabletop exercises are held regularly at the Senior and Executive management levels to validate roles and responsibilities and response protocols respective to cybersecurity threats. The outcomes of these tabletop exercises are reviewed annually at the Board level.

Employees, contractors, and third parties are required to immediately report any suspected cybersecurity threats to the Corporate Information Security team for triaging. Any threat assessed by the Corporate Information Security team that could impact the safety of customers or personnel, cause damage to, or threaten the confidentiality, integrity, or availability of information assets, or bring about significant business interruption, are escalated for further assessment. In the event that the CISO, in consultation with the Company’s Legal and Compliance teams, determines that a material cybersecurity incident has occurred, a dedicated Crisis Incident Response team comprised of individuals from various departments across the organization is assigned to coordinate all planned cybersecurity incident-related response activities. The Company will engage third party specialists to assist in any cybersecurity incident investigation, as needed.

Cybersecurity threats that are identified and deemed material are escalated and communicated directly to Senior and Executive Management and the Risk Committee of the Board. Materiality determinations are made under the Company’s Disclosure Controls and Procedures to ensure timely cybersecurity incident disclosure notification in accordance with securities laws and/or regulations.

Material Cybersecurity Threat Risks. Risks from cybersecurity threats have not materially affected the Company, its business strategy, results of operations, or financial condition for the year ended December 31, 2025. However, it is possible that the Company could suffer such losses in the future. Information regarding risks from material cybersecurity threats can be found under the section captioned “Operational Risk” contained in Item 1A. Risk Factors.

Governance. Oversight of information security risk and information technology risk is the responsibility of the Information Risk Committee, a management committee, with additional oversight from the Enterprise Risk Management Committee, a management committee, and the Risk and Technology Committees of the Board. On at least a quarterly basis, the Corporate Information Security team provides reports on updates to the Company’s information risk profile, emerging risks and threats, results of examinations, status of remediation plans and/or results of remediation activities, risk reports and risk assessment results, and risk metric results to the Information Risk Committee, who then provides such information to the Enterprise Risk Management Committee and the Risk Committee of the Board. In addition, on at least a quarterly basis, this information, along with updates on key cybersecurity initiatives, is shared with the Technology Committee of the Board, who provides oversight on information security and information technology strategy and governance.

Additional information regarding the Company’s risk management framework, including management-level and Board-level committee experience and expertise, oversight responsibilities, and information risk governance, can be found under the section captioned “Risk Governance Framework” contained in Item 1. Business.

Performance Graph

The performance graph compares the yearly percentage change in the Company’s cumulative total stockholder return on its common stock over the last five years to the cumulative total return of (i) the Standard & Poor’s 500 Index (“S&P 500 Index”) and (ii) the Keefe, Bruyette & Woods Regional Banking Index (“KRX Index”), assuming the reinvestment of dividends and an initial investment of $100 on December 31, 2020. The KRX Index is a market-capitalization weighted index comprised of 50 regional banks or thrifts located throughout the United States.

Cumulative total stockholder return is measured by dividing the sum of the cumulative amount of dividends for the measurement period, assuming dividend reinvestment, and the difference between the share price at the end and the beginning of the measurement period, by the share price at the beginning of the measurement period. The plotted points represent the cumulative total stockholder return on the last trading day of the year indicated. Historical performance shown on the graph is not necessarily indicative of future performance.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis provides information that management believes is necessary to understand the Company’s consolidated financial condition, results of operations, and cash flows for the year ended December 31, 2025, as compared to the year ended December 31, 2024. This information should be read in conjunction with the Consolidated Financial Statements, and the accompanying Notes thereto, contained in Part II - Item 8. Financial Statements and Supplementary Data, as well as other information set forth throughout this report. For discussion and analysis of the Company’s consolidated financial condition, results of operations, and cash flows for the year ended December 31, 2024, as compared to the year ended December 31, 2023, please refer to Part II - Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 3, 2025.

Economic Outlook

Actions and announcements related to changes in trade policies and other economic policies and practices, including tariffs, have created significant economic uncertainty in the U.S., which could contribute to higher inflation, increase the risk of a recession, and introduce further uncertainty as to the pace and direction of interest rate changes. Events such as these are outside of our control, but nonetheless may alter customer behavior, including borrowing, repayment, investment, and deposit practices, which could, in turn, adversely impact our business and financial results in future periods. While we cannot predict the potential impact that these changes and economic developments may have on us or our customers, we believe that our diverse businesses, strong capital position, unique deposit profile, and solid risk management framework allow us to operate in a range of economic environments.

Proposed Transaction with Banco Santander

On February 3, 2026, Webster entered into a Transaction Agreement with Banco Santander and Webster Virginia Corporation, a wholly owned subsidiary of Webster incorporated in the State of Virginia. The Transaction Agreement provides that, upon the terms and subject to the conditions set forth therein, Banco Santander will acquire Webster in two steps. First, Webster will merge with and into Webster Virginia Corporation, with Webster Virginia Corporation continuing as the surviving corporation in such merger. Second, immediately following the completion of such merger, Banco Santander will acquire all outstanding shares of Webster Virginia Corporation through a statutory share exchange. Based on Banco Santander’s closing stock price on February 2, 2026, the Transaction has an aggregate value of approximately $12.3 billion.

Under the terms of the Transaction Agreement, holders of Webster common stock will receive $48.75 in cash and 2.0548 ADSs (or Ordinary Shares in certain circumstances) for each share of Webster common stock that they own. The Transaction Agreement contains customary representations and warranties, covenants, and closing conditions. Completion of the Transaction remains subject to approval by the Federal Reserve and the European Central Bank, approval by the stockholders of each company, and other customary closing conditions. The Transaction is expected to close in the second half of 2026.

Non-GAAP Financial Measures

The non-GAAP financial measures identified in the preceding table provide both management and investors with information useful in understanding the Company’s financial position, results of operations, the strength of its capital position, and overall business performance. These non-GAAP financial measures are used by management for performance measurement purposes, as well as for internal planning and forecasting, and by securities analysts, investors, and other interested parties to assess peer company operating performance. Management believes that this presentation, together with the accompanying reconciliations, provides investors with a more complete understanding of the factors and trends affecting the Company’s business and allows investors to view its performance in a similar manner.

Tangible book value per common share represents stockholders’ equity, less preferred stock and goodwill and other net intangible assets (“tangible common equity”), divided by common shares outstanding at the end of the reporting period. The tangible common equity ratio represents tangible common equity divided by total assets, less goodwill and other net intangible assets (“tangible assets”). Both of these measures are used by management to evaluate the Company’s capital position. The return on average tangible common stockholders’ equity is calculated using net income less preferred stock dividends, adjusted for the tax-effected amortization of intangible assets, as a percentage of average tangible common equity. This measure is used by management to assess the Company’s performance against its peer financial institutions. The efficiency ratio, which represents the costs expended to generate a dollar of revenue, is calculated excluding certain non-operational items in order to measure how well the Company is managing its recurring operating expenses.

These non-GAAP financial measures should not be considered a substitute for GAAP-basis financial measures. Because
non-GAAP financial measures are not standardized, it may not be possible to compare these with other companies that present financial measures having the same or similar names.

The following tables reconcile non-GAAP financial measures to the most comparable financial measures defined by GAAP:

(1)The change attributable to mix, a combined impact of rate and volume, and other is included with the change due to rate.

Net interest income increased $0.2 billion, or 6.8%, from $2.3 billion for the year ended December 31, 2024, to $2.5 billion for the year ended December 31, 2025, reflecting increases of $4.6 billion, or 6.6%, in average total interest-earning assets and $4.5 billion, or 6.8%, in average total deposits and interest-bearing liabilities. Net interest margin remained flat at 3.42% for the years ended December 31, 2025, and 2024. The lower interest rate environment during the year ended December 31, 2025, as compared to the year ended December 31, 2024, primarily caused the average yield on average total interest-earning assets to decrease by 22 basis points and the average rate on average total deposits and interest-bearing liabilities to decrease by 24 basis points.

The change in average total interest-earnings assets was primarily attributed to the following items:

•Average loans and leases increased $2.4 billion, or 4.7%, primarily due to increases in commercial non-mortgage, residential mortgages, commercial real estate, and other consumer loans, partially offset by decreases in multi-family mortgages and asset-based lending.

•Average total investment securities increased $0.9 billion, or 5.2%, primarily due to the timing and volume of purchases, paydowns, and sales activities, particularly within the available-for-sale portfolio.

•Average interest-bearing deposits held at the FRB of New York increased $1.3 billion, or 180.8%, primarily due to management’s strategic decision to hold higher levels of on-balance sheet liquidity.

The change in average total deposits and interest-bearing liabilities was primarily attributed to the following items:

•Average total deposits increased $4.3 billion, or 6.8%, primarily due to an increase in money market deposits, which contributed to $2.8 billion of the change. The Company also experienced increases across all other deposit products, except for demand deposits and brokered certificates of deposit.

•Average FHLB advances increased $0.2 billion, or 9.2%, primarily due to a change in short-term funding mix.

Provision for Credit Losses

The provision for credit losses decreased $12.0 million, or 5.4% from $222.0 million for the year ended December 31, 2024 to $210.0 million for the year ended December 31, 2025, primarily due to improvements in risk rating migration and changes in commercial portfolio mix, partially offset by higher net charge-offs, changes in the macroeconomic forecast, economic uncertainty, and loan growth.

Additional information regarding the Company’s provision for credit losses and ACL can be found under the sections captioned “Loans and Leases” through “Allowance for Credit Losses on Loans and Leases” contained elsewhere in this Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations.

Loan and lease related fees decreased $5.7 million, or 7.5%, from $76.4 million for the year ended December 31, 2024, to $70.7 million for the year ended December 31, 2025, primarily due to lower loan servicing fees, factoring fees, and amendment fees, partially offset by lower mortgage servicing rights amortization and an increase in line usage fees.

Wealth and investment services decreased $2.2 million, or 6.8%, from $33.2 million for the year ended December 31, 2024, to $31.0 million for the year ended December 31, 2025, primarily due to a decrease in investment services, partially offset by an increase in personal trust fees.

The Cash surrender value of life insurance policies increased $5.5 million, or 19.9%, from $27.7 million for the year ended December 31, 2024, to $33.2 million for the year ended December 31, 2025, primarily due to bank-owned life insurance events in 2024, which resulted in a lower increase to the cash surrender value in the prior year.

Net gains (losses) on sale of investment securities changed $136.4 million, or 100.2%, from net (losses) of $136.2 million for the year ended December 31, 2024, to net gains $0.2 million for the year ended December 31, 2025.

The amounts presented in non-interest income include the portion of any losses that were not due to credit related factors.

Other income increased $18.9 million, or 21.0%, from $89.6 million for the year ended December 31, 2024, to $108.5 million for the year ended December 31, 2025, primarily due to a $16.0 million net loss on sale of the factored receivables portfolio in 2024, a $9.8 gain on extinguishment of long-term debt in 2025, a $4.0 million beneficial legal settlement in 2025, increased client hedging activities in 2025, and the decrease in the credit valuation adjustment on derivatives in 2025, partially offset by an $11.7 million net gain on sale of mortgage servicing rights in 2024, bank owned life insurance events in 2024, and a
$4.4 million net gain on sale of multi-family loans (securitization) in 2024.

Total non-interest expense increased $0.1 billion, or 5.8%, from $1.3 billion for the year ended December 31, 2024, to $1.4 billion for the year ended December 31, 2025, primarily due to increases in Compensation and benefits, Professional and outside services, Other expense, and Occupancy, partially offset by a decrease in Deposit insurance.

Compensation and benefits increased $58.9 million, or 7.7%, from $762.8 million for the year ended December 31, 2024, to $821.7 million for the year ended December 31, 2025, primarily due to higher performance-based incentives and increased compensation and employee benefits resulting from investments in human capital and risk management infrastructure, partially offset by a decrease in severance.

Occupancy increased $5.2 million, or 7.3%, from $72.2 million for the year ended December 31, 2024, to $77.4 million for the year ended December 31, 2025, primarily due to a one-time lease termination benefit in 2024.

Income Taxes

The Company recognized income tax expense of $257.3 million and $248.3 million for the years ended December 31, 2025, and 2024, respectively, reflecting effective tax rates of 20.4% and 24.4%, respectively. The increase in income tax expense is primarily due to the higher level of pre-tax income recognized in 2025, as compared to 2024. The higher effective tax rate in 2024 primarily reflects the recognition in 2024 of $42.3 million in net discrete tax expense during that period, which included a
$29.4 million DTA valuation adjustment resulting from a change in management’s estimate about the realizability of its SALT DTAs applicable to net operating loss carryforwards due to an estimated decrease in future taxable income for SALT purposes.

On July 4, 2025, the One Big Beautiful Bill Act was signed into law, which includes a broad range of tax reform provisions with varying effective dates. The Company has evaluated the changes in tax law and determined that the impact on its consolidated financial statements is not material.

At December 31, 2025, and 2024, the Company’s valuation allowance on its DTAs was $56.8 million and $64.4 million, respectively, of which $56.8 million and $62.7 million, respectively, were related to the portion of SALT net operating loss and credit carryforwards that, in management’s judgment, are not more likely than not to be realized. The $5.9 million decrease in the valuation allowance for SALT net operating loss and credit carryforwards from 2024 to 2025 is primarily attributed to the expiration of net operating loss carryforwards for which a valuation allowance existed at December 31, 2024. At
December 31, 2025, and 2024, the Company’s gross DTAs included $66.1 million and $67.7 million, respectively, applicable to SALT net operating loss and credit carryforwards that are available to offset future taxable income.

The ultimate realization of DTAs is dependent on the generation of future taxable income during the periods in which the net operating loss and credit carryforwards are available. In making its assessment, management considers the Company’s forecasted future results of operations, estimates the content and apportionment of its income by legal entity over the near term for SALT purposes, and also applies longer-term growth rate assumptions. Based on its estimates, management believes it is more likely than not that the Company will realize its DTAs, net of the valuation allowance, at December 31, 2025. However, it is possible that some or all of the Company’s net operating loss and credit carryforwards could expire unused, or that more net operating loss and credit carryforwards could be utilized than estimated, either as a result of changes in future forecasted levels of taxable income or if future economic or market conditions or interest rates were to vary significantly from the Company’s forecasts and, in turn, impact its future results of operations.

Commercial Banking’s PPNR decreased $80.4 million, or 7.5%, for the year ended December 31, 2025, as compared to the year ended December 31, 2024, due to decreases in net interest income and non-interest income and an increase in non-interest expense. The $51.8 million decrease in net interest income is primarily due to a lower net spread on loans and leases, partially offset by higher average loan and deposit balances. The $13.4 million decrease in non-interest income is primarily due to lower factoring and deposit service fees, and a non-recurring gain from a multi-family securitization event in 2024, partially offset by an increase in client hedging activities and syndication fees. The $15.2 million increase in non-interest expense is primarily due to increased investments in human capital, operational process improvements, technology, and higher foreclosed property and loan workout expenses.

Total portfolio originations for the years ended December 31, 2025, and 2024, were $12.9 billion and $9.7 billion, respectively. The $3.2 billion increase was primarily due to increased Commercial Real Estate, Middle Market, and Sponsor and Specialty Finance origination activities.

Consumer Banking’s PPNR decreased $15.2 million, or 3.3%, for the year ended December 31, 2025, as compared to the year ended December 31, 2024, due to a decrease in non-interest income and an increase in non-interest expense, partially offset by an increase in net interest income. The $26.7 million increase in net interest income is primarily due to higher average loan and deposit balances coupled with a higher interest rate spread on loans, partially offset by lower interest spreads on deposits. The $13.4 million decrease in non-interest income is primarily due to the net gain on sale of mortgage servicing rights in 2024, a gain on an investment portfolio sale in 2024, lower investment services income, and decreased deposit service fees, partially offset by increased loan servicing fees.

Loans increased $0.9 billion, or 7.9%, at December 31, 2025, as compared to at December 31, 2024, primarily due to growth in residential mortgages and other consumer loans, partially offset by net principal paydowns in home equity loans/lines of credit and business banking commercial loans. Total portfolio originations for the years ended December 31, 2025, and 2024, were $2.2 billion and $1.9 billion, respectively.

Deposits increased $0.3 billion, or 1.2%, at December 31, 2025, as compared to at December 31, 2024, primarily due to growth in online savings, money markets, certificates of deposit, and interest-bearing checking, partially offset by outflows in non-interest-bearing demand.

Assets under administration remained relatively flat at approximately $8.0 billion at December 31, 2025, and 2024, primarily due to increased investment account balances as a result of higher equity market valuations in 2025, partially offset by the sale of two investment portfolios.

Financial Condition

Total assets increased $5.1 billion, or 6.4%, from $79.0 billion at December 31, 2024, to $84.1 billion at December 31, 2025. The change in total assets was primarily attributed to the following items, which experienced changes greater than $100 million:

•Cash and cash equivalents increased $0.4 billion, primarily due to an increase in interest-bearing deposits held at the FRB of New York as a result of management’s strategic decision to hold higher levels of on-balance sheet liquidity;

•Total investment securities, net increased $0.5 billion, reflecting a $1.0 billion increase in the available-for-sale portfolio, partially offset by a $0.5 billion decrease in the held-to-maturity portfolio. The net increase in total investment securities was primarily due to purchases exceeding paydown activities, particularly across the Agency CMBS, Agency MBS, and CMBS categories;

•Loans and leases increased $4.1 billion, primarily due to $15.1 billion of originations during the year ended December 31, 2025, particularly across the commercial non-mortgage, commercial real estate, and residential mortgages categories, partially offset by net principal paydowns and the transfer of loans from portfolio to held for sale, particularly as it relates to joint venture activities;

•DTAs decreased $0.1 billion, primarily due to the deferred tax effect on the change in other comprehensive income and an increase in deferred tax expense for the year ended December 31, 2025;

•Accrued interest receivable and other assets increased $0.1 billion. Notable drivers of the change included increases in treasury derivative assets, LIHTC investments, other alternative investments, and accrued interest receivable, partially offset by decreases in prepaid expenses and other assets.

Total liabilities increased $4.7 billion, or 6.7%, from $69.9 billion at December 31, 2024, to $74.6 billion at December 31, 2025. The change in total liabilities was primarily attributed to the following items:

•Total deposits increased $4.0 billion, reflecting a $4.2 billion increase in interest-bearing deposits, partially offset by a $0.2 billion decrease in non-interest-bearing deposits. The net increase in interest-bearing deposits was primarily due to an increase in money market deposits, particularly from interSYNC, which contributed to $2.0 billion of the change. The Company also experienced increases across all other interest-bearing deposit categories except for savings deposits;

•Securities sold under agreements to repurchase increased $0.3 billion, primarily due to a change in short-term funding mix;

•FHLB advances increased $0.9 billion, also primarily due to a change in short-term funding mix;

•Long-term debt decreased $0.2 billion, primarily due to the repayment during the fourth quarter of 2025 of the subordinated notes due on November 1, 2030, and the subordinated notes due on December 30, 2029, partially offset by the issuance in the third quarter of 2025 of the subordinated notes due on September 11, 2035; and

•Accrued expenses and other liabilities decreased $0.3 billion. Notable drivers of the change included decreases in treasury derivative liabilities, unfunded commitments for LIHTC investments, accrued FDIC deposit insurance, and accrued interest payable, partially offset by increases in accrued compensation and other liabilities.

Total stockholders’ equity increased $0.4 billion, or 3.9%, from $9.1 billion at December 31, 2024, to $9.5 billion at December 31, 2025. The change in stockholders’ equity was attributed to the following items:

•Net income of $1.0 billion;

•Other comprehensive income, net of tax, of $205.5 million;

•Dividends paid to common and preferred stockholders of $267.6 million and $16.7 million, respectively;

•Stock-based compensation expense of $56.8 million;

•Stock options exercised of $0.1 million; and

Investment Securities

Through its Corporate Treasury function, the Company maintains and invests in debt securities that are primarily used to provide a source of liquidity for operating needs, as a means to manage the Company’s interest-rate risk, and to generate interest income. The Company’s investment securities are classified into two major categories: available-for-sale and
held-to-maturity.

The ALCO manages the Company’s investment securities in accordance with regulatory guidelines and corporate policies, which include limitations on aspects such as concentrations in and types of investments, as well as minimum risk ratings per type of security. In addition, the OCC may further establish individual limits on certain types of investments if the concentration in such security presents a safety and soundness concern. Although the Bank held the entirety of the Company’s investment securities portfolio at both December 31, 2025, and 2024, the Company may also directly hold investments.

The following table summarizes the carrying amount and percentage composition of the Company’s investment securities:

(1)The balances at December 31, 2025, and 2024, exclude the ACL recorded on held-to-maturity securities of $0.1 million and $0.2 million, respectively.

Available-for-sale securities increased $1.0 billion, or 11.1%, from $9.0 billion at December 31, 2024, to $10.0 billion at December 31, 2025, primarily due to purchases exceeding paydown activities, particularly across the Agency CMBS, Agency MBS, and CMBS categories. The average FTE yield on the available-for-sale portfolio was 4.74% for the year ended December 31, 2025, as compared to 4.17% for the year ended December 31, 2024. The 57 basis point increase is primarily due to higher yields on securities that were purchased in 2024 and 2025, as compared to the yields on securities with paydown activities or that were sold.

At December 31, 2025, and 2024, gross unrealized losses on available-for-sale securities were $0.5 billion and $0.7 billion, respectively. The $0.2 billion decrease is primarily due to lower market interest rates and lower securities’ spreads. On a quarterly basis, each available-for-sale security that is in an unrealized loss position is evaluated to determine whether the decline in fair value below the amortized cost basis is a result of any credit related factors. There was no ACL recorded on available-for-sale securities at December 31, 2025. At December 31, 2024, the ACL on available-for-sale securities was
$0.9 million, which related to a single Corporate debt security. Each of the Company’s available-for-sale securities in an unrealized loss position at December 31, 2025, is investment grade, current as to principal and interest, and their price changes are consistent with interest and credit spreads when adjusting for duration, convexity, rating, and industry differences. Based on current market conditions and the Company’s targeted balance sheet composition strategy, the Company intends to hold its available-for-sale securities in unrealized loss positions through the anticipated recovery period.

Held-to-maturity securities decreased $0.4 billion, or 5.6%, from $8.4 billion at December 31, 2024, to $8.0 billion at December 31, 2025, primarily due to paydown activities across the Agency MBS, Agency CMBS, and Municipal bonds and notes categories. There were no purchases of held-to-maturity securities during the year ended December 31, 2025. The average FTE yield on the held-to-maturity portfolio was 3.98% for the year ended December 31, 2025, as compared to 3.75% for the year ended December 31, 2024. The 23 basis point increase is primarily due to paydowns of lower yielding securities.

At December 31, 2025, and 2024, gross unrealized losses on held-to-maturity securities were $0.8 billion and $1.0 billion, respectively. The $0.2 billion decrease is primarily due to lower market interest rates and lower securities’ spreads. Held-to-maturity securities are evaluated for credit losses on a quarterly basis under the CECL methodology. At December 31, 2025, and 2024, the ACL on held-to-maturity securities was $0.1 million and $0.2 million respectively.

The weighted-average LTV ratio for non-owner occupied commercial real estate and multi-family loans at both December 31, 2025, and 2024, was 57%. The Company calculates its LTV ratios primarily using appraisals at origination unless a full appraisal is subsequently required based on deal-specific events.

Given the ongoing change in office demand driven by the acceptance of remote work options, the commercial real estate market has continued to experience an increase in office property vacancies. As such, commercial real estate performance across the U.S. related to the traditional office sector continues to be an area of uncertainty. At December 31, 2025, the outstanding principal balance of traditional office commercial real estate loans was approximately $733.8 million, which had corresponding reserves of $36.3 million. While the Company does anticipate ongoing change in the traditional office sector, management believes that its reserve levels reflect the expected credit losses in the portfolio.

Credit Policies and Procedures

The Bank has credit policies and procedures in place designed to support its lending activities within an acceptable level of risk, which are reviewed and approved by management and the Board on a regular basis. To assist with this process, management reviews reports generated by the Company’s loan reporting systems related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans, and potential problem loans.

Commercial non-mortgage, asset-based, and equipment finance loans are underwritten after evaluating and understanding the borrower’s ability to operate and service its debt. Assessment of the borrower’s management is a critical element of the underwriting process and credit decision. Once it has been determined that the borrower’s management possesses sound ethics and a solid business acumen, current and projected cash flows are examined to determine the ability of the borrower to repay obligations, as contracted. Commercial non-mortgage, asset-based, and equipment finance loans are primarily made based on the identified cash flows of the borrower, and secondarily on the underlying collateral provided by the borrower. However, the cash flows of borrowers may not be as expected, and the collateral securing these loans, as applicable, may fluctuate in value. Most commercial non-mortgage, asset-based, and equipment finance loans are secured by the assets being financed and may incorporate personal guarantees of the principal balance.

Commercial real estate loans, including multi-family, are subject to underwriting standards and processes similar to those for commercial non-mortgage, asset-based, and equipment finance loans. These loans are primarily viewed as cash flow loans, and secondarily as loans secured by real estate. Repayment of commercial real estate loans is largely dependent on the successful operation of the property securing the loan, the market in which the property is located, and the tenants of the property securing the loan. Management monitors and evaluates commercial real estate loans based on collateral, geography, and risk grade criteria. All transactions are appraised to determine market value. Commercial real estate loans may be adversely affected by conditions in the real estate markets or in the general economy. Management periodically utilizes third-party experts to provide insight and guidance about economic conditions and trends affecting its commercial real estate loan portfolio.

The Bank requires a valuation of real estate collateral, which generally includes third-party appraisals, at the time of origination or renewal in accordance with regulatory guidance. On an annual basis, appraisal assumptions and other factors are internally reviewed to determine whether an incremental third-party appraisal is warranted. New appraisals are typically obtained sooner if a loan becomes substandard or non-accrual.

Consumer loans are subject to policies and procedures developed to manage the specific risk characteristics of the portfolio. These policies and procedures, coupled with relatively small individual loan amounts and predominately collateralized loan structures, are spread across many different borrowers, minimizing the level of credit risk. Trend and outlook reports are reviewed by management on a regular basis, and policies and procedures are modified or developed, as needed. Underwriting factors for residential mortgage and home equity loans include the borrower’s FICO score, the loan amount relative to property value, and the borrower’s debt-to-income level. The Bank originates both qualified mortgage and non-qualified mortgage loans.

Allowance for Credit Losses on Loans and Leases

The ACL on loans and leases increased $29.8 million, or 4.3%, from $689.6 million at December 31, 2024, to $719.4 million at December 31, 2025, primarily due to additional reserves resulting from changes in the macroeconomic forecast, economic uncertainty, and loan growth, partially offset by net charge-offs, improvements in risk rating migration, and changes in commercial portfolio mix.

The following table summarizes the percentage allocation of the ACL across the loans and leases categories:

			December 31,
			2025									2024

Methodology

The Company’s ACL on loans and leases is considered to be a critical accounting policy. The ACL on loans and leases is a contra-asset account that offsets the amortized cost basis of loans and leases for the credit losses that are expected to occur over the life of the asset. Executive management reviews and advises on the adequacy of the allowance on a quarterly basis, which is maintained at a level that management deems to be sufficient to cover expected losses within the loan and lease portfolios.

The ACL on loans and leases is determined using the CECL model, whereby an expected lifetime credit loss is recognized at the origination or purchase of an asset, including those acquired through a business combination, which is then reassessed at each reporting date over the contractual life of the asset. The calculation of expected credit losses includes consideration of past events, current conditions, and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Generally, expected credit losses are determined through a pooled, collective assessment of loans and leases with similar risk characteristics. However, if the risk characteristics of a loan or lease change such that it no longer aligns to that of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. The total ACL on loans and leases recorded by management represents the aggregated estimated credit loss determined through both the collective and individual assessments.

Collectively Assessed Loans and Leases. Collectively assessed loans and leases are segmented based on product type and credit quality, and expected losses are determined using models that follow a PD, LGD, or EAD framework. Under these frameworks, expected credit losses are calculated as the product of the probability of a loan defaulting, expected loss rate given the occurrence of a default, and the expected exposure of a loan at default. Summing the product across loans over their lives yields the lifetime expected credit losses for a given portfolio. The Company’s PD and LGD calculations are predictive models that measure the current risk profile of the loan pools using forecasts of future macroeconomic conditions, historical loss information, loan-level risk attributes, and credit quality indicators. The calculation of EAD follows an iterative process to determine the expected remaining principal balance of a loan based on historical paydown rates for loans of a similar segment within the same portfolio. The calculation of portfolio exposure in future quarters incorporates expected losses, the loan’s amortization schedule, and prepayment rates.

The Company incorporates forecasts of macroeconomic variables in the determination of expected credit losses. Macroeconomic variables are selected for each class of financing receivable based on relevant factors, such as asset type and the correlation of the variables to credit losses, among others. Data from the forecast scenario of these macroeconomic variables are used as inputs to the modeled loss calculation.

The Company’s models incorporate a baseline and a downside macroeconomic forecast scenario, and management weights the scenarios based on reviews of variable forecasts and comparisons to expectations using readily available data to arrive at a macroeconomic scenario for each quarter end over a reasonable and supportable forecast period. The development of the reasonable and supportable forecast assumes that each portfolio will revert to its long-term loss rate expectation. The reasonable and supportable forecast period is two years, after which the reversion period is one year. Models use output reversion and revert to mean historical portfolio and risk rating specific loss rates on a straight-line basis in the third year of the forecast.

A portion of the collective ACL is comprised of qualitative adjustments for risk characteristics that are not reflected or captured in the quantitative models, but are likely to impact the measurement of estimated credit losses. Qualitative adjustments are based on management’s judgment of the Company, market, industry, or business specific data, and may be applied in relation to economic forecasts when relevant facts and circumstances are expected to impact credit losses, particularly in times of significant volatility in economic activity. Qualitative factors that are generally used in the Company’s models for all loan and lease portfolios include, but are not limited to, nature and volume of portfolio growth, credit quality trends, underwriting exception levels, quality of internal loan review, credit concentrations, and staffing trends.

During the third quarter of 2025, the Company completed a refresh of its CECL models, incorporating additional loss history and enhancements to modeling methodologies used in the estimation process, which resulted in an increase in the quantitative portion of the collective ACL relative to the total ACL on loans and leases. The refreshed CECL models reflect the estimated impact of economic conditions including tariffs, the risk of recession/inflation, and the general economic uncertainty associated with these evolving risks. The change in probability-weighting of macroeconomic forecast scenarios resulted in an increase to the collective ACL of $30.4 million from December 31, 2024, to December 31, 2025. The qualitative portion of the collective ACL accounted for approximately 22% and 39% of the total ACL on loans and leases at December 31, 2025, and 2024, respectively. The composition of qualitative reserves primarily relates to credit quality trends and credit concentrations, which decreased from the prior year as a result of the effects of the CECL model refresh and improvements in overall commercial risk rating migration trends.

Individually Assessed Loans and Leases. If the risk characteristics of a loan or lease change such that it no longer matches the risk characteristics of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. Generally, all non-accrual loans and loans with a charge-off are individually assessed. The measurement method used to calculate the expected credit loss on an individually assessed loan or lease depends on the type and whether the loan or lease is considered to be collateral dependent. Methods for collateral dependent commercial loans are either based on the fair value of the collateral less estimated costs to sell when the basis of repayment is the sale of collateral, or the present value of the expected cash flows from the operation of the collateral. For non-collateral dependent loans, either a discounted cash flow method or other loss factor method is used. Any individually assessed loan or lease for which no specific allowance is deemed necessary is either the result of sufficient cash flows or sufficient collateral coverage relative to the amortized cost of the asset.

Additional information regarding the Company’s ACL methodology can be found within Note 1: Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

Asset Quality Ratios

The Company manages asset quality using risk tolerance levels established through the Company’s underwriting standards, servicing, and management of its loan and lease portfolio. Loans and leases for which a heightened risk of loss has been identified are regularly monitored to mitigate further deterioration and preserve asset quality in future periods. Non-performing assets, credit losses, and net charge-offs are considered by management to be key measures of asset quality.

The following table summarizes key asset quality ratios and their underlying components:

Liquidity and Capital Resources

The Company manages its cash flow requirements through proactive liquidity measures at both the Company and the Bank. In order to maintain stable, cost-effective funding, and to promote overall balance sheet strength, the liquidity position of the Company is continuously monitored, and adjustments are made to balance sources and uses of funds, as appropriate.

Cash inflows are provided through a variety of sources, including principal and interest payments on loans and investments, unpledged securities that can be sold or utilized to secure funding, and new deposits. The Company is committed to maintaining a strong base of core deposits, which consists of demand, health savings, interest-bearing checking, money market, and savings accounts, to support growth in its loan portfolios. Management actively monitors the interest rate environment and makes adjustments to its deposit strategy in response to evolving market conditions, funding needs, and client relationship dynamics.

Company Liquidity. The primary source of liquidity at the Company is dividends from the Bank. To a lesser extent, investment income, net proceeds from investment sales, borrowings, and public offerings may provide additional liquidity. The Company generally uses its funds for principal and interest payments on senior notes, subordinated notes, and junior subordinated debt, dividend payments to preferred and common stockholders, repurchases of its common stock, and purchases of debt and equity securities, as applicable.

There are certain restrictions on the Bank’s payment of dividends to the Company, which can be found within the section captioned “Supervision and Regulation” in Part I - Item 1. Business, and within Note 13: Regulatory Capital and Restrictions in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data. During the year ended December 31, 2025, the Bank paid $900.0 million in dividends to the Company. At December 31, 2025, there was $634.6 million of retained earnings available for the payment of dividends by the Bank to the Company. On January 28, 2026, the Bank was approved to pay the Company $300.0 million in dividends in the first quarter of 2026.

The quarterly cash dividend to common stockholders remained at $0.40 per common share throughout 2025. On January 28, 2026, it was announced that the Company’s Board had declared a quarterly cash dividend of $0.40 per share on Webster common stock. For the Series F Preferred Stock and Series G Preferred Stock, quarterly cash dividends of $328.125 per share and $16.25 per share, respectively, were declared. The Company continues to monitor economic forecasts, anticipated earnings, and its capital position in the determination of its dividend payments. In accordance with the Transaction Agreement with Banco Santander, quarterly cash dividends on Webster common stock, the Series F Preferred Stock, and the Series G Preferred Stock may not exceed $0.40 per share, $328.125 per share, and $16.25 per share, respectively, without prior written consent from Banco Santander.

The Company maintains a common stock repurchase program, which was approved by the Board, that permits management to repurchase shares of its common stock in open market or private transactions, through block trades, and pursuant to any trading plan that may be adopted in accordance with Rule 10b5-1 of the SEC, subject to the availability and trading price of stock, general market conditions, alternative uses for capital, regulatory considerations, and the Company’s financial performance. On April 30, 2025, the Board increased management’s authority to repurchase shares of Webster common stock under the repurchase program by $700.0 million. During the year ended December 31, 2025, the Company repurchased 10,933,584 shares under the repurchase program at a weighted-average price of $54.30 per share, totaling $593.7 million. At December 31, 2025, the Company’s remaining purchase authority was $334.3 million. In accordance with the Transaction Agreement with Banco Santander, the Company paused repurchases under its stock repurchase program through the completion of the Transaction.

In addition, the Company will periodically acquire common shares outside of the repurchase program related to employee stock compensation plan activity. During the year ended December 31, 2025, the Company repurchased 402,502 shares at a weighted-average price of $56.55 per share, totaling $22.8 million, for this purpose.

Webster Bank Liquidity. The Bank’s primary source of funding is its core deposits. Including time deposits, the Bank had a loan to total deposit ratio of 82.3% and 81.1% at December 31, 2025, and 2024, respectively.

The Bank is required by OCC regulations to maintain a sufficient level of liquidity to ensure safe and sound operations. The adequacy of liquidity, as assessed by the OCC, depends on factors such as overall asset and liability structure, market conditions, competition, and the nature of the institution’s deposit and loan customers. At December 31, 2025, the Bank exceeded all regulatory liquidity requirements. The Company has designed a detailed contingency plan in order to respond to any liquidity concerns in a prompt and comprehensive manner, including early detection of potential problems and corrective action to address liquidity stress scenarios.

Capital Requirements. The Company and the Bank are subject to various regulatory capital requirements administered by the federal bank regulatory agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that could have a direct material effect on the Company’s Consolidated Financial Statements. Under capital adequacy guidelines and/or the regulatory framework for prompt corrective action (applies to the Bank only), both the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated pursuant to regulatory directives. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the Company and the Bank to maintain minimum ratios of CET1 Risk-Based Capital, Tier 1 Risk-Based Capital, Total Risk-Based Capital, and Tier 1 Leverage Capital, as defined in the regulations.

The following table presents the minimum ratios required as of December 31, 2025, and 2024:

						Adequately Capitalized						Well Capitalized
CET1 Risk-Based Capital						4.5		%				6.5		%
Tier 1 Risk-Based Capital						6.0						8.0
Total Risk-Based Capital						8.0						10.0
Tier 1 Leverage Ratio						4.0						5.0

At December 31, 2025, and 2024, both the Company and the Bank were classified as “well-capitalized.” Management believes that no events or changes have occurred subsequent to year-end and through the date of this Annual Report on Form 10-K that would change this designation.

The Company’s and the Bank’s capital ratios, which exceeded minimum regulatory requirements, were as follows:

						December 31,
						2025 (1)												2024 (1)
(Dollars in thousands)						Capital/Assets						Ratio						Capital/Assets						Ratio
Webster Financial Corporation
CET1 Risk-Based Capital						$	6,441,440					11.20		%				$	6,318,876					11.54		%
Tier 1 Risk-Based Capital						6,725,419						11.69						6,602,855						12.06
Total Risk-Based Capital						7,861,688						13.67						7,800,717						14.24
Tier 1 Leverage Ratio						6,725,419						8.33						6,602,855						8.70

(1)In accordance with regulatory capital rules, the Company elected to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and a subsequent three-year transition period, which ended on December 31, 2024. During the three-year transition period, regulatory capital ratios phased out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2024, the Company was allowed 25%, of the regulatory capital benefit as of December 31, 2021. Full absorption occurred in 2025.

Additional information regarding the required regulatory capital levels and ratios applicable to the Company and the Bank can be found within Note 13: Regulatory Capital and Restrictions in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

Sources and Uses of Funds

Sources of Funds. Deposits are the primary source of cash flows for the Bank’s lending activities and general operational needs. Loan and securities repayments, proceeds from sales of loans and securities held for sale, and maturities also provide cash flows. While scheduled loan and securities repayments are a relatively stable source of funds, prepayments and other deposit inflows are influenced by economic conditions and prevailing interest rates, the timing of which are inherently uncertain. Additional sources of funds are provided by both short-term and long-term borrowings, and to a lesser extent, dividends received as part of the Bank’s membership with the FHLB of Boston and FRB of New York.

Deposits. The Bank offers a wide variety of checking and savings deposit products designed to meet the transactional and investment needs of its consumer and business customers. The Bank’s deposit services include, but are not limited to, ATM and debit card use, direct deposit, ACH payments, mobile banking, internet-based banking, banking by mail, account transfers, and overdraft protection, among others. The Bank manages the flow of funds in its deposit accounts and interest rates consistent with FDIC regulations. The Bank’s Consumer and Digital Pricing Committee and its Commercial and Institutional Liability and Loan Pricing Committee both meet regularly to determine pricing and marketing initiatives. In addition, the Bank may use brokered certificates of deposit as a funding source, which are managed based on established limits set by the ALCO.

Total deposits were $68.8 billion and $64.8 billion at December 31, 2025, and 2024, respectively. The $4.0 billion net increase in total deposits was primarily due an increase in money market deposits, particularly from interSYNC, which contributed to $2.0 billion of the change. The Company also experienced increases across all other deposit categories, except for savings and non-interest-bearing demand deposits.

The following table summarizes daily average balances of deposits by type and the weighted-average rates paid thereon:

Uninsured deposits represent the portion of deposit accounts in U.S. offices that exceed the FDIC insurance limit or similar state deposit insurance regimes, and amounts in any other uninsured investment or deposit accounts that are classified as deposits and not subject to any federal or state deposit insurance regimes. The Company calculates its uninsured deposit balances based on the methodologies and assumptions used for regulatory reporting requirements, which includes an estimated portion and affiliate deposits. At December 31, 2025, and 2024, total uninsured deposits as per regulatory reporting requirements and reported on Schedule RC-O of the Bank’s Call Report were $23.8 billion and $22.6 billion, respectively.

The following table summarizes additional uninsured deposits information after certain exclusions:

(Dollars in thousands)			December 31, 2025
Uninsured deposits, per regulatory reporting requirements			$	23,795,358

Table of Contents

Uninsured deposits, after adjusting for affiliate deposits and collateralized deposits, represented 22.3% of total deposits at December 31, 2025. Management believes that this presentation provides a more accurate view of deposits at risk given that affiliate deposits are not customer-facing, and therefore are eliminated upon consolidation, and collateralized deposits are secured by other means. As of the date of this Annual Report on Form 10-K, the Company’s uninsured deposits as a percentage of total deposits, adjusted for affiliate deposits and collateralized deposits, is consistent with the percentage reported at December 31, 2025.

The following table summarizes the portion of U.S. time deposits in excess of the FDIC insurance limit and time deposits otherwise uninsured by contractual maturity:

(In thousands)			December 31, 2025
Portion of U.S. time deposits in excess of insurance limit			$	578,376
Time deposits otherwise uninsured with a maturity of:
3 months or less			$	321,774
Over 3 months through 6 months			194,438
Over 6 months through 12 months			61,731
Over 12 months			433

Borrowings. The Bank’s primary borrowing sources include securities sold under agreements to repurchase, federal funds purchased, FHLB advances, and long-term debt. Total borrowings were $4.3 billion and $3.4 billion at December 31, 2025, and 2024, respectively, and represented 5.1% and 4.3% of total assets, respectively. The $1.0 billion increase is primarily due increases of $0.9 billion in FHLB advances and $0.3 billion in securities sold under agreements to repurchase, partially offset by a decrease of $0.2 billion in long-term debt.

Securities sold under agreements to repurchase are generally a form of short-term funding for the Bank in which it sells securities to counterparties with an agreement to buy them back in the future at a fixed price. Securities sold under agreements to repurchase totaled $0.6 billion and $0.3 billion at December 31, 2025, and December 31, 2024, respectively. The $0.3 billion increase is primarily due to a change in short-term funding mix.

The Bank may also purchase term and overnight federal funds to meet its short-term liquidity needs. There were no federal funds purchased at December 31, 2025, and 2024.

FHLB advances are not only utilized as a source of funding, but also for interest rate risk management purposes. FHLB advances totaled $3.0 billion and $2.1 billion at December 31, 2025, and 2024, respectively. The $0.9 billion increase is primarily due to a change in short-term funding mix.

Long-term debt consists of senior notes maturing in 2029, subordinated notes maturing in 2035, and junior subordinated notes maturing in 2033. Long-term debt totaled $0.7 billion and $0.9 billion at December 31, 2025, and 2024, respectively. The $0.2 billion decrease is primarily due to the repayment during the fourth quarter of 2025 of the subordinated notes due on November 1, 2030, and the subordinated notes due on December 30, 2029, partially offset by the issuance in the third quarter of 2025 of the subordinated notes due on September 11, 2035.

The Bank had additional borrowing capacity from the FHLB of Boston and FRB of New York of $7.9 billion and $17.3 billion, respectively, at December 31, 2025. Unencumbered investment securities of $1.0 billion at December 31, 2025, could have been used for collateral on borrowings or to increase borrowing capacity by either $0.8 billion with the FHLB of Boston or $0.9 billion with the FRB of New York.

The following table summarizes daily average balances of borrowings by type and the weighted-average rates paid thereon:

			Years ended December 31,

Federal Home Loan Bank and Federal Reserve Bank Stock. The Bank is a member of the FHLB System, which consists of 11 district FHLBs, each of which is subject to the supervision and regulation of the Federal Housing Finance Agency. An activity-based capital stock investment in a FHLB is required in order for the Bank to maintain its membership and access advances and other extensions of credit for sources of funds and liquidity purposes. The FHLB capital stock investment is restricted as there is no market for it, and it can only be redeemed by the applicable FHLB. The Bank held FHLB of Boston capital stock of $125.2 million and $91.7 million at December 31, 2025, and 2024, respectively. During the year ended December 31, 2025, the Bank received $7.4 million in dividends from the FHLB of Boston. The most recent FHLB quarterly cash dividend in 2025 was paid on November 4, 2025, in an amount equal to an annual yield of 7.39%.

The Bank is also required to hold FRB stock equal to 6% of its capital and surplus, of which 50% is paid. The remaining 50% is subject to call when deemed necessary by the Federal Reserve. Similar to FHLB stock, the FRB capital stock investment is restricted as there is no market for it, and it can only be redeemed by the applicable FRB. The Bank held FRB of New York capital stock of $231.2 million and $229.6 million at December 31, 2025, and 2024, respectively. During the year ended December 31, 2025, the Bank received $9.9 million in dividends from the FRB of New York. The most recent FRB semi-annual cash dividend in 2025 was paid on December 31, 2025, in an amount equal to an annual yield of 4.18%.

Uses of Funds. The Company enters into various contractual obligations in the normal course of business that require future cash payments and that could impact its short-term and long-term liquidity and capital resource needs. The following table summarizes significant fixed and determinable contractual obligations at December 31, 2025. The actual timing and amounts of future cash payments may differ from the amounts presented. Based on the Company’s current liquidity position, it is expected that our sources of funds will be sufficient to fulfill these obligations when they come due.

(1)Interest payments on borrowings and obligations arising from agreements to purchases goods or receive services have been excluded.

The Company enters into commitments to invest in venture capital and private equity funds and tax credit structures to assist the Bank in meeting its responsibilities under the CRA. The total unfunded commitment for these alternative investments was $764.2 million at December 31, 2025. However, the timing of capital calls cannot be reasonably estimated, and depending on the nature of the contract, the entirety of the capital committed by the Company may not be called.

Pension obligations are funded by the Company, as needed, to provide for participant benefit payments as it relates to the Company’s frozen, non-contributory, qualified defined benefit pension plan. Decisions to contribute to the defined benefit pension plan are made based upon pension funding requirements under the Pension Protection Act, the maximum amount deductible under the Internal Revenue Code, the actual performance of plan assets, and trends in the regulatory environment. The Company was not required to contribute to the defined benefit pension plan in 2025, nor does it currently anticipate that it will be required to contribute in 2026. The Company’s non-qualified supplemental executive retirement plans and other post-employment benefit plans are unfunded. Expected future net benefit payments related to the Company’s defined benefit pension and other postretirement benefit plans included $13.0 million in less than one year, $27.5 million in one to three years, $28.4 million in three to five years, and $72.0 million after five years.

In connection with the completion of a multi-family securitization in 2024, the Company assumed an obligation to reimburse, or guarantee, losses incurred by the multi-family securitization trusts of up to 12% of the aggregate UPB of the loans at the time of sale. Essentially, this obligation represents a first credit loss enhancement provided by the Company. Based on the credit quality of the multi-family loans, among other factors, the Company estimated the amount of its reimbursement obligation to be $3.3 million at December 31, 2025. The Company has not yet been required to make any guarantee payments to Freddie Mac. However, in the event that value of the assets in the multi-family securitization trusts significantly declined, the Company’s maximum exposure to loss could be $36.4 million.

In connection with the SecureSave acquisition completed in December 2025, the Company recorded contingent consideration at fair value related to one earn‑out agreement. The earn‑out is based on total program deposits measured as of three future measurement dates, with a payment due only if total program deposits exceed the program deposit threshold and, if so, (i) equal to total program deposits multiplied by the applicable earn-out rate for the measurement dates on December 31, 2026, and December 31, 2027, and (ii) equal to the total program deposits in excess of the program deposit threshold multiplied by the earn-out rate for the measurement date on December 31, 2028. The contingent consideration is payable in cash up to an aggregate maximum of $35.0 million.

In connection with the formation of the joint venture with Marathon Asset Management, the Company and Marathon Asset Management have agreed to collectively make a capital contribution to a certain investment fund formed in connection with the joint venture (the “Fund”) for an amount equal to the lesser of $20 million or 2% of total capital commitments from limited partners to the Fund. At its discretion, the Company may contribute amounts exceeding this commitment, up to BHC Act limitations (less than 25% of the Fund’s total equity interests and less than 5% of its voting equity interests).

At December 31, 2025, the Company’s Consolidated Balance Sheet reflects a liability for uncertain tax positions of $10.4 million and $5.3 million of accrued interest and penalties, respectively. The ultimate timing and amount of any related future cash settlements cannot be predicted with reasonable certainty.

In the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit and commercial and standby letters of credit, which involve, to a varying degree, elements of credit risk. Since many of these commitments are expected to expire unused or be only partially funded, the total commitment amount of $13.2 billion at December 31, 2025, does not necessarily reflect future cash payments.

In November 2023, the FDIC issued a final rule implementing a special assessment for certain banks to recover losses to the DIF associated with protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. At December 31, 2025, the Company’s remaining accrual for its estimated special assessment charge was $5.9 million, which will be collected over the one remaining quarterly assessment period. The FDIC retains the right to cease collection early, extend the special assessment collection period, and impose shortfall special assessments if actual losses exceed the amounts collected. The Company continues to monitor the estimated loss attributable to the protection of uninsured depositors at Silicon Valley Bank and Signature Bank, which could impact the amount of its accrued liability.

Asset/Liability Management and Market Risk

An effective asset/liability management process must balance the risks and rewards from both short-term and long-term interest rate risk when determining the Company’s strategy and action. To facilitate this process, interest rate sensitivity is monitored on an ongoing basis by the Company’s ALCO, whose primary goal is to manage interest rate risk and maximize net income and net economic value over time in changing interest rate environments. Limits for earnings at risk are set for parallel ramps in interest rates over a 12-month period of up and down 100, 200, and 300 basis points, and for interest rate curve twist shocks of up and down 50 and 100 basis points. Limits for net economic value, referred to as equity at risk, are set for parallel shocks in interest rates of up and down 100, 200, and 300 basis points. The ALCO also regularly reviews earnings at risk scenarios for non-parallel changes in interest rates, as well as longer-term earnings at risk for up to four years in the future.

Management measures interest rate risk using simulation analysis and asset/liability modeling software to calculate the Company’s earnings at risk and equity at risk. Key assumptions relate to the behavior of interest rates and spreads, prepayment speeds, and the run-off of deposits. From these simulations, interest rate risk is quantified, and appropriate strategies are formulated and implemented.

Deposit beta is defined as the change in deposit rate for interest-bearing and non-interest-bearing deposits due to changes in market rates (increase or decrease). The model assumes a deposit beta by each product. The deposit beta for each product is a function of prior rate cycle, prior deposit beta, current rate cycle expectation, level of competition, and line of business input.

Earnings at risk is defined as the change in net interest income due to changes in interest rates. Essentially, interest rates are assumed to change up or down in a parallel fashion, and the net interest income results in each scenario are compared to a flat rate base scenario. The flat rate base scenario holds the end of period yield curve constant over a 12-month forecast horizon. The earnings at risk simulation analysis incorporates assumptions about balance sheet changes (i.e., product mix, growth, and loan and deposit pricing). Overall, it is a measure of short-term interest rate risk. At December 31, 2025, and 2024, the flat rate base scenario assumed a federal funds rate of 3.75% and 4.50%, respectively. The federal funds rate target range was 3.50-3.75% at December 31, 2025, and 4.25-4.50% at December 31, 2024.

Equity at risk is defined as the change in the net economic value of financial assets and financial liabilities due to changes in interest rates compared to a base net economic value. Equity at risk analyzes sensitivity in the present value of cash flows over the expected life of existing financial assets, financial liabilities, and off-balance sheet financial instruments. It is a measure of the long-term interest rate risk to future earnings’ streams embedded in the current balance sheet.

The Bank regularly evaluates rate exposure over long-term using equity at risk. The Bank deploys various techniques to a yield curve shocks, static balance sheet, basis risks, and options risks. The level of uncertainty around key assumption increases with time, which may limit its effectiveness.

Asset sensitivity is defined as earnings or net economic value increasing when interest rates rise and decreasing when interest rates fall, as compared to a base scenario. In other words, financial assets are more sensitive to changing interest rates than liabilities, and therefore, re-price faster. Likewise, liability sensitivity is defined as earnings or net economic value decreasing when interest rates rise and increasing when interest rates fall, as compared to a base scenario.

Key assumptions underlying the present value of cash flows include the behavior of interest rates and spreads, asset prepayment speeds, and attrition rates on deposits. Cash flow projections from the model are compared to market expectations for similar collateral types and adjusted based on experience with the Bank’s own portfolio. The model’s valuation results are compared to observable market prices for similar instruments whenever possible. The behavior of deposit and loan customers is studied using historical time series analysis to model future customer behavior under varying interest rate environments.

The equity at risk simulation process uses multiple interest rate paths generated by an arbitrage-free trinomial lattice term structure model. The base case rate scenario, against which all others are compared, currently uses the month-end SOFR/swap yield curve as a starting point to derive forward rates for future months. Using interest rate swap option volatilities as inputs, the model creates multiple rate paths for this scenario with forward rates as the mean. In shock scenarios, the starting yield curve is shocked up or down in a parallel fashion. Future rate paths are then constructed in a similar manner to the base case scenario.

Cash flows for all financial instruments are generated using product specific prepayment models and account specific system data for properties such as maturity date, amortization type, coupon rate, repricing frequency, and repricing date. The asset/liability simulation software is enhanced with a mortgage prepayment model and a collateralized mortgage obligation database. Financial instruments with explicit options (i.e., caps, floors, puts, and calls) and implicit options (i.e., prepayment and early withdrawal abilities) require such modeling approach to quantify value and risk more accurately.

On the asset side, risk is impacted the most by residential mortgage loans and mortgage-backed securities, which can typically prepay at any time without penalty and may have embedded caps and floors. In the loan portfolio, floors are a benefit to interest income in low interest rate environments. Floating-rate loans at floors pay a higher interest rate than a loan at a fully indexed rate without a floor, as with a floor, there is a limit on how low the interest rate can fall. As market rates rise, however, the interest rate paid on these loans does not rise until the fully indexed rate rises through the contractual floor.

On the liability side, there is a large concentration of customers with indeterminate maturity deposits who have options to add or withdraw funds from their accounts at any time. Implicit floors on deposits, based on historical data, are modeled. The Bank also has the option to change the interest rate paid on these deposits at any time.

Four main tools are used for managing interest rate risk:

•the size, duration, and credit risk of the investment portfolio;

•the size and duration of the wholesale funding portfolio;

•interest rate contracts; and

•the pricing and structure of loans and deposits.

The ALCO meets frequently to make decisions on the investment and funding portfolios based on the economic outlook, its interest rate expectations, the risk position, and other factors. The ALCO delegates pricing and product design responsibilities to individuals and sub-committees, but continuously monitors and influences their actions on a regular basis.

Various interest rate contracts, including futures, options, swaps, caps, and floors, can be used to manage interest rate risk. These contracts involve, to varying degrees, levels of credit risk and interest rate risk. The notional amount of the derivative instrument, or the amount from which interest and other payments are derived, is not exchanged, and therefore, should not be used as a measure of credit risk.

In addition, certain derivative instruments are used by the Bank to manage the risk of loss associated with its mortgage banking activities. Generally, prior to closing and funds disbursement, an interest-rate lock commitment is extended to the borrower. During this time, the Bank is subject to the risk that market interest rates may change, which could impact pricing on loan sales. In an effort to mitigate this risk, the Bank establishes forward delivery sales commitments, thereby setting the sales price.

The Company will also hold futures, options, and forward foreign currency exchange contracts to minimize the price volatility of certain financial assets and financial liabilities. Changes in the market value of these derivative positions are recognized in earnings. Additional information regarding derivatives can be found within Note 16: Derivative Financial Instruments in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

The following table summarizes the estimated impact that gradual parallel changes in interest rates of up and down 100, 200, and 300 basis points might have on the Company’s net interest income over a 12-month period starting at December 31, 2025, and 2024, as compared to actual net interest income and assuming no changes in interest rates:

			-300bp			-200bp			-100bp			+100bp			+200bp			+300bp
December 31, 2025			(0.9)%			(0.6)%			(0.2)%			0.2%			0.2%			0.1%
December 31, 2024			(1.6)%			(0.6)%			—%			0.4%			0.6%			0.8%

Asset sensitivity in terms of net interest income decreased at December 31, 2025, as compared to at December 31, 2024, primarily due to an increase in fixed-rate assets, including investment securities and residential loans, and increased client hedging activities.

The following table summarizes the estimated impact that yield curve twists or immediate non-parallel changes in interest rates of up and down 50 and 100 basis points might have on the Company’s net interest income over a 12-month period starting at December 31, 2025, and 2024:

			Short End of the Yield Curve															Long End of the Yield Curve
			-100bp			-50bp			+50bp			+100bp						-100bp			-50bp			+50bp			+100bp
December 31, 2025			1.3%			0.6%			(0.5)%			(1.1)%						(2.3)%			(1.1)%			1.0%			1.9%
December 31, 2024			2.1%			1.0%			(0.7)%			(1.6)%						(2.2)%			(1.0)%			1.0%			1.9%

These non-parallel scenarios are modeled with the short end of the yield curve moving up or down 50 and 100 basis points, while the long end of the yield curve remains unchanged, and vice versa. The short end of the yield curve is defined as terms less than eighteen months, and the long end of the yield curve is defined as terms greater than eighteen months. The results reflect the annualized impact of immediate interest rate changes.

Sensitivity to the short end of the yield curve for net interest income decreased at December 31, 2025, as compared to at December 31, 2024, primarily due to an increase in our interest-bearing deposits (cash balance) and floating-rate loans. Sensitivity to the long end of the yield curve generally remained stable from December 31, 2024, to December 31, 2025.

Changes in economic value can best be described through duration, which is a measure of the price sensitivity of financial assets and financial liabilities due to changes in interest rates. For fixed-rate financial instruments, it can be thought of as the weighted-average expected time to receive future cash flows, whereas for floating-rate financial instruments, it can be thought of as the weighted-average expected time until the next rate reset. Overall, the longer the duration, the greater the price sensitivity due to changes in interest rates. Generally, increases in interest rates reduce the economic value of fixed-rate financial assets as future discounted cash flows are worth less at higher interest rates. In a rising interest rate environment, the economic value of financial liabilities decreases for the same reason. A reduction in the economic value of financial liabilities is a benefit to the Company. Floating-rate financial instruments may have durations as short as one day, and therefore, may have very little price sensitivity due to changes in interest rates.

Duration gap represents the difference between the duration of financial assets and financial liabilities. A duration gap at or near zero would imply that the balance sheet is matched, and therefore, would exhibit no change in estimated economic value for changes in interest rates. At December 31, 2025, and 2024, the Company’s duration gap was zero.

These earnings and net economic value estimates are subject to factors that could cause actual results to differ, and also assume that management does not take any additional action to mitigate any positive or negative effects from changing interest rates. Management believes that the Company’s interest rate risk position at December 31, 2025, represents a reasonable level of risk given the current interest rate outlook. Management continues to monitor interest rates and other relevant factors given recent market volatility and is prepared to take additional action, as necessary.

Critical Accounting Estimates

The preparation of the Company’s Consolidated Financial Statements, and accompanying notes thereto, in accordance with GAAP and practices generally applicable to the financial services industry, requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the disclosure of contingent assets and liabilities. While management’s estimates are made based on historical experience, current available information, and other factors that are deemed to be relevant, actual results could significantly differ from those estimates.

Accounting estimates are necessary in the application of certain accounting policies and can be susceptible to significant change in the near term. Critical accounting estimates are those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had, or are reasonably likely to have, a material impact on the Company’s financial condition or results of operations. Management has identified that the Company’s most critical accounting estimates are those related to the ACL on loans and leases and business combinations accounting policies. These accounting policies and their underlying estimates are discussed directly with the Audit Committee of the Board.

Allowance for Credit Losses on Loans and Leases

The ACL on loans and leases is a reserve established through a provision for credit losses charged to expense, which represents management’s best estimate of expected lifetime credit losses within the Company’s loan and lease portfolios at the balance sheet date. The calculation of expected credit losses is determined using predictive methods and models that follow a PD, LGD, EAD, or loss rate framework, and include consideration of past events, current conditions, macroeconomic variables (i.e., unemployment, gross domestic product, property values, and interest rate spreads), and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Changes to the ACL on loans and leases, and therefore, to the related provision for credit losses, can materially affect financial results.

The determination of the appropriate level of ACL on loans and leases inherently involves a high degree of subjectivity and requires the Company to make significant estimates of current credit risks and trends using existing qualitative and quantitative information, and reasonable and supportable forecasts of future economic conditions, all of which may undergo frequent and material changes. Changes in economic conditions affecting borrowers and macroeconomic variables that the Company is more susceptible to, unforeseen events such as natural disasters and pandemics, along with new information regarding existing loans, identification of additional problem loans, the fair value of underlying collateral, and other factors, both within and outside the Company’s control, may indicate the need for an increase or decrease in the ACL on loans and leases.

The Company’s ACL on loans and leases is sensitive to changes in forecasted macroeconomic conditions during the reasonable and supportable forecast period. The Company performs sensitivity analyses using probability weighted scenarios to quantify the impact on the ACL resulting from hypothetical changes in key macroeconomic variable inputs to the CECL models, including, but not limited to, gross domestic product, the unemployment rate, and property values. As of December 31, 2025, the results of this sensitivity analysis indicated that, by applying a 100% weighting to a 90th percentile downside scenario (meaning that there is a 90% probability that the economy will perform better and a 10% probability that it will perform worse) the Company’s ACL on loans and leases would increase by approximately $91.3 million, or 12.7%. This does not represent management’s expectations of changes in our estimate of expected credit losses or in the macroeconomic environment. The downside scenario used is characterized by an economic recession beginning in the first quarter of 2026 and lasting through the third quarter of 2026 and assumes that from the fourth quarter of 2025 through the third quarter of 2026, real gross domestic product declines cumulatively by approximately 2.6%; unemployment begins to increase significantly sharply in the first quarter of 2026, peaking at approximately 8.4% in the first quarter of 2027; and house prices drop approximately 12.3% over the course of 2026.

Executive management reviews and advises on the adequacy of the ACL on loans and leases on a quarterly basis. Although the overall balance is determined based on specific portfolio segments and individually assessed assets, the entire balance is available to absorb credit losses for any of the loan and lease portfolios. Additional information regarding the determination of the ACL on loans and leases, including the Company’s valuation methodology, can be found in Part II under the section captioned “Allowance for Credit Losses on Loans and Leases” contained elsewhere in this Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and within Note 1: Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements contained in Item 8. Financial Statements and Supplementary Data.

Business Combinations

The acquisition method of accounting generally requires that the identifiable assets acquired and liabilities assumed in business combinations are recorded at fair value as of the acquisition date. The determination of fair value often involves the use of internal or third-party valuation techniques, such as discounted cash flow analyses. Particularly, the valuation techniques used to estimate the fair value of the core deposit intangible asset acquired in the Ametros acquisition included estimates related to discount rates, client attrition rates, an alternative cost of funds, and other relevant factors, which are inherently subjective. A description of the valuation methodologies used to estimate the fair values of the significant assets acquired and liabilities assumed in the Ametros acquisition can be found within Note 2: Business Developments in the Notes to Consolidated Financial Statements contained in Part II - Item 8. Financial Statements and Supplementary Data.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors

Webster Financial Corporation:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Webster Financial Corporation and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2026 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Assessment of the allowance for credit losses for certain commercial loans and leases evaluated on a collective basis

As discussed in Notes 1 and 4 to the consolidated financial statements, the Company’s total allowance for credit losses as of December 31, 2025 was $719.4 million, a portion of which related to the allowance for credit losses for certain commercial loans and leases evaluated on a collective basis (the Commercial Allowance). The Commercial Allowance includes the measure of expected credit losses on a collective (pooled) basis for those loans and leases with similar risk characteristics. The Company’s collectively assessed loans and leases are segmented based on product type and credit quality and expected losses are determined using a model that follows a probability of default (PD), loss given default (LGD), and exposure at default (EAD) framework. The expected credit losses are calculated as the product of the Company’s estimate of PD, LGD, and individual loan level EAD. The Company’s PD and LGD calculations use a predictive model that measures the current risk profile of the loan pools using forecasts of future macroeconomic conditions, historical loss information, loan-level risk attributes and credit quality indicators. The Company’s model incorporates baseline and downside macroeconomic forecast scenarios, and management weights the scenarios based on reviews of variable forecasts and comparisons to expectations using readily available data to arrive at a macroeconomic scenario over a reasonable and supportable forecast period. The development of the reasonable and supportable forecast assumes that each portfolio will revert to its long-term loss rate expectation. The reasonable and supportable forecast period is two years after which the reversion period is one year. The model uses output reversion and revert to mean historical portfolio loss rates on a straight-line basis in the third year of the forecast. A portion of

the Commercial Allowance is comprised of qualitative adjustments for risk characteristics that are not reflected or captured in the quantitative model but are likely to impact the measurement of expected credit losses.

We identified the assessment of the Commercial Allowance as a critical audit matter. A high degree of audit effort, including specialized skills and knowledge, and subjective and complex auditor judgment was involved in the assessment due to significant measurement uncertainty. Specifically, the assessment encompassed the evaluation of the Commercial Allowance methodology, including the methods and model used to estimate (1) the PD, LGD, and EAD, and their significant assumptions, including the baseline and downside macroeconomic forecast scenarios and macroeconomic variables and (2) qualitative adjustments and their significant assumptions not reflected in the PD and LGD model and EAD method. The assessment also included an evaluation of the conceptual soundness and performance of the PD and LGD model and EAD method. In addition, auditor judgment was required to evaluate the sufficiency of audit evidence obtained.

The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls related to the Company’s measurement of the Commercial Allowance estimate, including controls over the:

•evaluation of the Commercial Allowance methodology

•continued use and appropriateness of changes made to certain PD and LGD model and EAD method

•identification and determination of the significant assumptions used in the PD and LGD model and EAD method

•procedures performed by the Company to validate the model is fit for use and appropriate to estimate the lifetime loss

•evaluation of qualitative adjustments, including the significant assumptions, and

•analysis of the Collective Allowance results, trends, and ratios.

We evaluated the Company’s process to develop the Commercial Allowance estimate by testing certain sources of data, factors, and assumptions that the Company used, and considered the relevance and reliability of such data, factors, and assumptions. In addition, we involved credit risk professionals with specialized skills and knowledge, who assisted in:

•evaluating the Company’s Commercial Allowance methodology for compliance with U.S. generally accepted accounting principles

•evaluating judgments made by the Company relative to the assessment and performance testing of PD and LGD model and EAD method by comparing them to relevant Company-specific metrics and trends and the applicable industry practices

•assessing the conceptual soundness and performance of the PD and LGD model by inspecting the model documentation to determine whether the model is suitable for the intended use

•evaluating the selection of the economic forecast scenarios and underlying macroeconomic variables by comparing them to the Company’s business environment and relevant industry practices

•evaluating the methodology and assumptions used to develop the qualitative factors and the effect of those factors on the Commercial Allowance compared with credit trends and identified limitations of the underlying quantitative model.

We also assessed the sufficiency of the audit evidence obtained related to the Commercial Allowance estimate by evaluating the cumulative results of the audit procedures and potential bias in the accounting estimate.

WEBSTER FINANCIAL CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1: Summary of Significant Accounting Policies

Nature of Operations

The Company is a bank holding company that has elected to be treated as a financial holding company under the BHC Act, incorporated under the laws of Delaware in 1986, and headquartered in Stamford, Connecticut. As of December 31, 2025, the Company had $84.1 billion in total consolidated assets.

The Bank is a commercial bank with a national bank charter focused on providing financial products and services to businesses, individuals, and families. While its core footprint spans the Northeast from the New York metropolitan area to Rhode Island and Massachusetts, certain businesses operate in extended geographies. The Bank offers three differentiated lines of business: Commercial Banking, Healthcare Financial Services, and Consumer Banking.

Basis of Presentation

The Consolidated Financial Statements have been prepared in accordance with GAAP, and include the accounts of the Company and all other entities in which the Company has a controlling financial interest. Intercompany transactions and balances have been eliminated in consolidation. Assets under administration or assets under management that the Company holds or manages in a fiduciary or agency capacity for customers are not included on the accompanying Consolidated Balance Sheets. Certain prior period amounts presented in the Consolidated Statement of Cash Flows and disclosed in Note 12: Accumulated Other Comprehensive (Loss), Net of Tax and Note 18: Retirement Benefit Plans have been reclassified to conform to the current year’s presentation. These reclassifications did not have a significant impact on the Company’s Consolidated Financial Statements.

Principles of Consolidation

The purpose of Consolidated Financial Statements is to present the results of operations and the financial position of the Company and its subsidiaries as if the consolidated group were a single economic entity. In accordance with the applicable accounting guidance for consolidations, the Consolidated Financial Statements include any VOE in which the Company has a controlling financial interest and any VIE for which the Company is deemed to be the primary beneficiary. The Company generally consolidates its VOEs if the Company, directly or indirectly, owns more than 50% of the outstanding voting shares of the entity, and if the non-controlling stockholders do not hold any substantive participating or controlling rights. The Company evaluates VIEs to understand the purpose and design of the entity, and its involvement in the ongoing activities of the VIE, and will consolidate the VIE if it has (i) the power to direct the activities of the VIE that most significantly affect the VIE’s economic performance, and (ii) an obligation to absorb losses of the VIE, or the right to receive benefits from the VIE, that could potentially be significant to the VIE. The Company accounts for unconsolidated partnerships and certain other investments using the equity method of accounting if it has the ability to significantly influence the operating and financial policies of the investee. This is generally presumed to exist when the Company owns between 20% and 50% of a corporation’s voting common stock or in-substance common stock, or when it has greater than 3% to 5% interest in a limited partnership or similarly structured entity. Additional information regarding consolidated and non-consolidated VIEs can be found within Note 14: Variable Interest Entities.

Use of Estimates

The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Consolidated Financial Statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Business Combinations

Business combinations are accounted for under the acquisition method, in which the identifiable assets acquired and liabilities assumed are generally measured and recognized at fair value as of the acquisition date, with the excess of the purchase price over the fair value of the net assets acquired recognized as goodwill. Items such as acquired ROU lease assets and operating lease liabilities as lessee, employee benefit plans, and income-tax related balances are recognized in accordance with other applicable GAAP, which may result in measurements that differ from fair value. After the adoption of ASU No. 2021-08—Business Combinations (Topic 805)—Accounting for Contract Assets and Contract Liabilities from Contracts with Customers, contract assets and contract liabilities from contracts with customers, may result in measurements that differ from fair value as well. The Company uses estimates and assumptions as part of the purchase price allocation process to determine the fair value of assets acquired and liabilities assumed as of the acquisition date. These estimates and assumptions are inherently uncertain and subject to refinement during the measurement period, which may extend for up to one year from the acquisition date.

Table of Contents

Business combinations are included in the Consolidated Financial Statements from the respective dates of acquisition. Historical reporting periods reflect only the results of legacy Webster operations. Acquisition-related costs are expensed in the period incurred and presented within the applicable non-interest expense category. Additional information regarding the Company’s business combinations can be found within Note 2: Business Developments.

Cash and Cash Equivalents

Cash and cash equivalents is comprised of Cash and due from banks and Interest-bearing deposits. Cash equivalents have an original maturity of three months or less.

Cash and due from banks includes cash on hand, certain deposits at the FRB of New York, and cash due from banks. Restricted cash related to Federal Reserve requirements, cash collateral received on derivative positions, and cash due from a bank held in connection with a compensating balance arrangement are also included in Cash and due from banks.

Interest-bearing deposits includes deposits at the FRB of New York in excess of reserve requirements and federal funds sold to other financial institutions. Restricted cash related to a deposit with contractual use limitations held in connection with a third-party arrangement is also included in Interest-bearing deposits.

Investments in Debt Securities

Debt security transactions are recognized on the trade date, which is the date the order to buy or sell the security is executed. Investments in debt securities are classified as available-for-sale or held-to-maturity at the time of purchase. Any classification change subsequent to the trade date is reviewed for compliance with corporate objectives and accounting policies.

Debt securities classified as available-for-sale are recorded at fair value with unrealized gains and losses recorded as a component of AOCL. If a debt security is transferred from available-for-sale to held-to-maturity, it is recorded at fair value at the time of transfer and any respective gain or loss would be recorded as a separate component of AOCL and amortized as an adjustment to interest income over the remaining life of the security. Debt securities classified as available-for-sale are reviewed for credit losses when the fair value of a security falls below the amortized cost basis and the decline is evaluated to determine if any portion is attributable to credit loss. The decline in fair value attributable to credit loss is recorded directly to earnings, with a corresponding allowance for credit loss, limited to the amount that fair value is less than the amortized cost. If the credit quality subsequently improves, previously recorded allowance amounts may be reversed. An available-for-sale debt security will be placed on non-accrual status if collection of principal and interest in accordance with contractual terms is doubtful. When the Company intends to sell an impaired available-for-sale debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovery of the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings through non-interest income. The gain or loss on sale is calculated using the carrying value plus any related AOCL balance associated with the securities sold.

Debt securities classified as held-to-maturity are those in which the Company has the ability and intent to hold to maturity. Debt securities classified as held-to-maturity are recorded at amortized cost net of unamortized premiums and discounts. Discount accretion income and premium amortization expense are recognized as interest income using the effective interest method, with consideration given to prepayment assumptions on mortgage-backed securities. Premiums are amortized to the earliest call date for debt securities purchased at a premium, with explicit, non-contingent call features and are callable at a fixed price and preset date. Debt securities classified as held-to-maturity are reviewed for credit losses under the CECL model with an allowance recorded on the balance sheet for expected lifetime credit losses. The ACL is calculated on a pooled basis using statistical models which include forecasted scenarios of future economic conditions. Forecasts revert to long-run loss rates implicitly through the economic scenario, generally over three years. If the risk for a particular security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration. The non-accrual policy for held-to-maturity debt securities is the same as for available-for-sale debt securities.

A zero credit loss assumption is maintained for U.S. Treasuries and agency-backed securities in both the available-for-sale and held-to-maturity portfolios, as applicable. This assumption is subject to quarterly review to ensure it remains appropriate. Additional information regarding investments in debt securities can be found within Note 3: Investment Securities.

Investments in Equity Securities

The Company’s accounting treatment for non-consolidated equity investments differs for those with and without readily determinable fair values. Equity investments with readily determinable fair values are recorded at fair value with changes in fair value recorded in non-interest income. For equity investments without readily determinable fair values and are not already accounted for under the equity method, the Company elected the measurement alternative, and therefore carries these investments at cost, less impairment, if any, plus or minus changes in observable prices. Certain equity investments that do not have a readily available fair value may qualify for NAV measurement based on specific requirements. The Company’s alternative investments accounted for at NAV consist of investments in non-public entities that generally cannot be redeemed since the Company’s investments are distributed as the underlying equity is liquidated. On a quarterly basis, the Company reviews its equity investments without readily determinable fair values for impairment. If the equity investment is considered impaired, an impairment loss equal to the amount by which the carrying value exceeds its fair value is recorded through a charge to earnings. The impairment loss may be reversed in a subsequent period if there are observable transactions for the identical or similar investment of the same issuer at a higher amount than the carrying amount that was established when the impairment was recognized. Impairments, as well as upward or downward adjustments resulting from observable price changes in orderly transactions for identical or similar investments, are included in non-interest income.

Equity investments in entities that finance affordable housing and other community development projects provide a return primarily through the realization of tax benefits. The Company applies the proportional amortization method to account for its investments in qualified affordable housing projects.

Investment in Federal Home Loan Bank and Federal Reserve Bank Stock

The Bank is a member of the FHLB and the Federal Reserve System, and is required to maintain an investment in capital stock of both a FHLB and FRB. Based on redemption provisions, FHLB and FRB stock has no quoted market value and is carried at cost. Membership stock is reviewed for impairment if economic circumstances would warrant review.

Loans Held for Sale

Loans that are classified as held for sale at the time of origination are accounted for under the fair value option. Loans not originated for sale but subsequently transferred to held for sale are valued at the lower of cost or fair value on an individual asset basis. Any cost amount in excess of fair value is recorded as a valuation allowance and recognized as a reduction of other non-interest income. Interest income on loans held for sale is recognized based on contractual rates and is reflected in Loans held for sale interest income on the accompanying Consolidated Statements of Income. Gains or losses on the sale of loans held for sale are recorded as part of Other income on the accompanying Consolidated Statements of Income.

For the purpose of presentation in the accompanying Consolidated Statements of Cash Flows, cash flows from loans are classified based on management’s intent to either sell the loan or hold the loan as an investment for the foreseeable future. When management’s intent is to sell the loan, the cash flows of that loan are presented as operating activities. When management’s intent is to hold the loan as an investment for the foreseeable future, the cash flows of that loan are presented as investing activities. Additionally, proceeds from the sale of loans that were originated for sale are presented as operating activities, and proceeds from the sale of loans that were originated for investment and then subsequently transferred to held for sale are presented as investing activities consistent with the original classification.

Transfers and Servicing of Financial Assets

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is generally considered to have been surrendered when: (i) the transferred assets are legally isolated from the Company or its consolidated affiliates, even in bankruptcy or other receivership, (ii) the transferee has the right to pledge or exchange the assets with no conditions that constrain the transferee and provide more than a trivial benefit to the Company, and (iii) the Company does not maintain the obligation or unilateral ability to reclaim or repurchase the assets. Transfers of financial assets that do not qualify for sale accounting are reported as collateralized borrowings. Accordingly, the related assets remain on the Company’s consolidated balance sheets and continue to be reported and accounted for as if the transfer had not occurred as discussed within the next policy below.

The Company sells financial assets in the normal course of business, the majority of which are residential mortgage loan sales to government-sponsored enterprises through established programs, as well as commercial loan sales through participation agreements, and other individual or portfolio loan and securities sales. In accordance with the accounting guidance for asset transfers, the Company considers any ongoing involvement with transferred assets in determining whether the assets should be derecognized from the balance sheet. With the exception of servicing, the Company’s continuing involvement with financial assets sold is minimal, and generally is limited to market customary representation and warranty clauses covering certain characteristics of the mortgage loans that were sold, and the Company’s origination process. The gain or loss on sale depends on the previous carrying amount of the transferred financial assets, the consideration received, and the fair value of any other assets obtained or liabilities incurred in exchange for the transferred assets.

83

Table of Contents

When the Company sells financial assets, it may retain servicing rights and/or other interests in the financial assets. Servicing assets and any other interests held by the Company are initially measured at fair value, and subsequently measured using the amortization method.

Securities Sold Under Agreements to Repurchase

These agreements are accounted for as secured financing transactions since the Company maintains effective control over the transferred investment securities and the transfer meets the other criteria for such treatment. Obligations to repurchase the sold investment securities are reflected as a liability on the accompanying Consolidated Balance Sheets. The investment securities sold with agreement to repurchase to wholesale dealers are transferred to a custodial account for the benefit of the dealer or to the bank with whom each transaction is executed. The dealers or banks may sell, loan, or otherwise dispose of such securities to other parties in the normal course of their operations and agree to resell to the Company the same securities at the maturity date of the agreement. The Company also enters into repurchase agreements with Bank customers. The investment securities sold to Bank customers with agreements to repurchase are not transferred, but internally pledged to the repurchase agreement transaction. As such, the underlying investment securities pledged remain on the accompanying Consolidated Balance Sheets. Additional information regarding securities sold under agreements to repurchase can be found within Note 10: Borrowings.

Loans and Leases

Loans and leases are stated at the principal amount outstanding, net of amounts charged-off, unamortized premiums and discounts, and deferred loan and lease fees or costs, which are recognized as yield adjustments in interest income using the effective interest method. These yield adjustments are amortized over the contractual life of the related loans and leases and are adjusted for prepayments as they occur. Interest on loans and leases is credited to interest income as earned based on the interest rate applied to principal amounts outstanding. The Company has elected to present accrued interest receivable separately from the amortized cost basis of Loans and leases on the accompanying Consolidated Balance Sheets. Amounts of cash receipts and cash payments for loans and leases are presented net within Investing activities on the Consolidated Statements of Cash Flows.

Non-accrual Loans

Loans are placed on non-accrual status when full collection of principal and interest in accordance with contractual terms is not expected based on available information, which generally occurs when principal or interest payments become 90 days delinquent unless the loan is well secured and in the process of collection, or sooner if circumstances indicate that the borrower may be unable to meet contractual principal or interest payments. The Company considers a loan to be “well-secured” when it is secured by collateral in the form of liens on, or pledges of, real or personal property that have a realizable value sufficient to discharge the debt in full, or when it is secured by a contractual guarantee of a financially responsible party. The Company considers a loan “in the process of collection” if collection of the debt is proceeding in due course either through legal action or through collection efforts not involving legal action that are reasonably expected to result in repayment of the debt or in its restoration to a current status in the near future.

When loans and leases are placed on non-accrual status, the accrual of interest income and the amortization or accretion of premiums, discounts, and deferred fees and costs is discontinued, and any previously accrued interest is reversed as a reduction of interest income. For commercial loans and leases, if the Company determines that repayment of non-accrual loans and leases is not expected, any payment received is applied to principal until the unpaid balance has been fully recovered. Any excess is then credited to interest income. For consumer loans, if the Company determines that principal can be repaid, interest payments are taken into income as received on a cash basis.

Loans are generally removed from non-accrual status when they become current as to principal and interest or demonstrate a period of performance under the contractual terms and, in the opinion of management, are fully collectible as to principal and interest. For commercial loans, a sustained period of repayment performance is generally required. Pursuant to regulatory guidance, a loan discharged under Chapter 7 of the U.S. bankruptcy code is removed from non-accrual status when full repayment of the remaining pre-discharged contractual principal and interest is expected, and there have been at least six consecutive months of current payments. Additional information regarding non-accrual loans and leases can be found within Note 4: Loans and Leases.

Allowance for Credit Losses on Loans and Leases

The ACL on loans and leases, which is established through a provision charged to expense, is a contra-asset account that offsets the amortized cost basis of loans and leases for the credit losses that are expected to occur over the life of the asset. Executive management reviews and advises on the adequacy of the allowance on a quarterly basis, which is maintained at a level that management deems to be sufficient to cover expected credit losses within the loan and lease portfolios. An ACL on accrued interest for a loan is not measured since accrued interest income is reversed against interest income for non-accrual loans immediately after their non-accrual classification.

84

Table of Contents

The ACL on loans and leases is determined using the CECL model, whereby an expected lifetime credit loss is recognized at the origination or purchase of an asset, including those acquired through a business combination, which is then reassessed at each reporting date over the contractual life of the asset. The calculation of expected credit losses includes consideration of past events, current conditions, and reasonable and supportable economic forecasts that affect the collectability of the reported amounts. Generally, expected credit losses are determined through a pooled, collective assessment of loans and leases with similar risk characteristics. However, if the risk characteristics of a loan or lease change such that it no longer aligns to that of the collectively assessed pool, it is removed from the population and individually assessed for credit losses. The total ACL on loans and leases recorded by management represents the aggregated estimated credit loss determined through both the collective and individual assessments.

Collectively Assessed Loans and Leases. Collectively assessed loans and leases are segmented based on product type and credit quality, and expected losses are determined using models that follow a PD, LGD, or EAD framework. Under these frameworks, expected credit losses are calculated as the product of the probability of a loan defaulting, expected loss rate given the occurrence of a default, and the expected exposure of a loan at default. Summing the product across loans over their lives yields the lifetime expected credit losses for a given portfolio. The Company’s PD and LGD calculations are predictive models that measure the current risk profile of the loan pools using forecasts of future macroeconomic conditions, historical loss information, loan-level risk attributes, and credit quality indicators. The calculation of EAD follows an iterative process to determine the expected remaining principal balance of a loan based on historical paydown rates for loans of a similar segment within the same portfolio. The calculation of portfolio exposure in future quarters incorporates expected losses, the loan’s amortization schedule, and prepayment rates.

The Company incorporates forecasts of macroeconomic variables in the determination of expected credit losses. Macroeconomic variables are selected for each class of financing receivable based on relevant factors, such as asset type and the correlation of the variables to credit losses, among others. Data from the forecast scenario of these macroeconomic variables are used as inputs to the modeled loss calculation.

The Company’s models incorporate a baseline and a downside macroeconomic forecast scenario, and management weights the scenarios based on reviews of variable forecasts and comparisons to expectations using readily available data to arrive at a macroeconomic scenario for each quarter end over a reasonable and supportable forecast period. The development of the reasonable and supportable forecast assumes that each portfolio will revert to its long-term loss rate expectation. The reasonable and supportable forecast period is two years, after which the reversion period is one year. Models use output reversion and revert to mean historical portfolio and risk rating specific loss rates on a straight-line basis in the third year of the forecast.

The commercial models use unemployment, gross domestic product, corporate profits, housing starts, and retail sales (for commercial unfunded); the residential models use the Case-Shiller Home Price Index and the Federal Housing Finance Agency Home Price Index. Forecasted economic scenarios are sourced from a third party. Data from the baseline forecast scenario is used as the input to the modeled loss calculation. Changes in forecasts of macroeconomic variables will impact expectations of lifetime credit losses calculated by the loss models. However, the impact of changes in macroeconomic forecasts may be different for each portfolio and will reflect the credit quality and nature of the underlying assets at that time.

A portion of the collective ACL is comprised of qualitative adjustments for risk characteristics that are not reflected or captured in the quantitative models, but are likely to impact the measurement of estimated credit losses. Qualitative adjustments are based on management’s judgment of the Company, market, industry, or business specific data, and may be applied in relation to economic forecasts when relevant facts and circumstances are expected to impact credit losses, particularly in times of significant volatility in economic activity. Qualitative factors that are generally used in the Company’s models for all loan and lease portfolios include, but are not limited to, nature and volume of portfolio growth, credit quality trends, underwriting exception levels, quality of internal loan review, credit concentrations, and staffing trends.

In addition to the above considerations, the ACL calculation includes expectations of prepayments and recoveries. Extensions, renewals, and modifications are not included in the collective assessment.

Individually Assessed Loans and Leases. When loans and leases no longer align to the risk characteristics of the collectively assessed pool, they are removed from the collectively assessed population and individually assessed for credit losses. Generally, all non-accrual loans and loans with a charge-off are individually assessed.

85

Table of Contents

Individual assessment for commercial loans that are considered to be collateral dependent is based on the fair value of the collateral less estimated cost to sell, the present value of the expected cash flows from the operation of the collateral, or a probability-weighted scenario approach of both of these methods. If a loan is not collateral dependent, the individual assessment is based on a discounted cash flow approach. For collateral dependent commercial loans and leases, the Company’s process requires the Company to determine the fair value of the collateral by obtaining a third-party appraisal or asset valuation, an interim valuation analysis, blue book reference, or other internal methods. Whenever the Company has a third-party real estate appraisal performed by independent licensed appraisers, a licensed in-house appraisal officer or qualified individual reviews these appraisals for compliance with the Financial Institutions Reform Recovery and Enforcement Act and the Uniform Standards of Professional Appraisal Practice.

Individual assessment for consumer loans are based on the fair value of collateral less the estimated costs to sell or loss factor approach based on historical loss rates. For residential and consumer collateral dependent loans, a third-party appraisal is obtained upon loan default. Fair value of the collateral for residential and consumer collateral dependent loans is reevaluated every six months, by either obtaining a new appraisal or other internal valuation method. Fair value is also reassessed, with any excess amount charged off, for residential and home equity loans that reach 180 days past due per Federal Financial Institutions Examination Council guidelines.

A fair value shortfall relative to the amortized cost balance is reflected as an allowance within the ACL on loans and leases. Subsequent to an appraisal or other fair value estimate, should reliable information come to management’s attention that the value has declined further, an additional allowance may be recorded to reflect the particular situation, thereby increasing the ACL on loans and leases. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. Any individually assessed loan for which no specific allowance is necessary is the result of either sufficient cash flow or sufficient collateral coverage relative to the amortized cost. Additional information regarding the ACL on loans and leases can be found within Note 4: Loans and Leases.

Charge-off of Uncollectible Loans

If all or a portion of a loan is deemed to be no longer collectible upon the occurrence of a loss-confirming event, a charge-off may be recognized. Charge-offs reduce the amortized cost basis of the loan with a corresponding reduction to the ACL. For commercial loans, loss confirming events usually involve the receipt of specific adverse information about the borrower. The Company will generally recognize charge-offs for commercial loans on a case-by-case basis based on the review of the entire credit relationship and financial condition of the borrower. Loss-confirming events for consumer loans, such as bankruptcy or protracted delinquency, are typically based on established thresholds rather than by specific adverse information about the borrower.

PCD Loans and Leases

PCD loans and leases are defined as those that have experienced a more-than-insignificant deterioration in credit quality since origination. The Company considers a variety of factors to evaluate and identify whether acquired loans are PCD, including but not limited to, nonaccrual status, delinquency, whether the borrower is experiencing financial difficulty, partial charge-offs, decreases in FICO scores, risk rating downgrades, and other factors. Upon acquisition, expected credit losses are added to the fair value of individual PCD loans and leases to determine the amortized cost basis. After initial recognition, any changes to the estimate of expected credit losses, favorable or unfavorable, are recorded as a provision for credit loss during the period of change.

PCD accounting is also applied to loans and leases previously charged-off by the acquiree if the Company has contractual rights to the cash flows at the acquisition date. The Company recognizes an additional ACL for amounts previously charged-off by the acquiree with a corresponding increase to the amortized costs basis of the acquired asset. Balances deemed to be uncollectible are immediately charged-off in accordance with the Company’s charge-off policies, resulting in the establishment of the initial ACL for PCD loans and leases to be recorded net of these uncollectible balances.

Allowance for Credit Losses on Unfunded Loan Commitments

The ACL on unfunded loan commitments provides for potential exposure inherent with funding the unused portion of legal commitments to lend that are not unconditionally cancellable by the Company. Accounting for unfunded loan commitments follows the CECL model. The calculation of the allowance includes the probability of funding to occur and a corresponding estimate of expected lifetime credit losses on amounts assumed to be funded. Loss calculation factors are consistent with the ACL methodology for funded loans using the PD and LGD applied to the underlying borrower risk and facility grades, a draw down factor applied to utilization rates, relevant forecast information, and management’s qualitative factors. The ACL on unfunded credit commitments is included within Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets. Additional information regarding the ACL on unfunded loan commitments can be found within
Note 22: Commitments and Contingencies.

Foreclosed and Repossessed Assets

Real estate acquired through foreclosure or completion of a deed in lieu of foreclosure and other assets acquired through repossession are recorded at fair value less estimated cost to sell at the date of transfer. Subsequent to the acquisition date, the foreclosed and repossessed assets are carried at the lower of cost or fair value less estimated selling costs and are included within Accrued interest receivable and other assets on the accompanying Consolidated Balance Sheets. Independent appraisals generally are obtained to substantiate fair value and may be subject to adjustment based upon historical experience or specific geographic trends impacting the property. Upon transfer to OREO, the excess of the loan balance over fair value less cost to sell is charged off against the ACL. Subsequent write-downs in value, maintenance costs as incurred, and gains or losses upon sale are charged to Other expense on the accompanying Consolidated Statements of Income.

Property and Equipment

Property and equipment is carried at cost, less accumulated depreciation and amortization. Depreciation and amortization is computed on a straight-line basis over the estimated useful lives of the assets, as illustrated in the following table. If shorter, leasehold improvements are amortized over the terms of the respective leases.

			Minimum						Maximum
Building and improvements			5			-			40			years
Leasehold improvements			5			-			20			years
Furniture, fixtures, and equipment			5			-			10			years
Data processing equipment and software			3			-			7			years

Repairs and maintenance costs are expensed as incurred, while significant improvements are capitalized. Property and equipment that is actively marketed for sale is reclassified to assets held for disposition. The cost and accumulated depreciation and amortization of property and equipment that is sold, retired, or otherwise disposed of, is eliminated from accounts and any resulting gain or loss is included in Other expense on the accompanying Consolidated Statements of Income.

Operating Leases

The Company determines if an arrangement is a lease at inception by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset for a period of time in exchange for consideration. As lessee, operating leases with a term greater than one year are recognized as lease liabilities and corresponding ROU assets on the lease commencement date. The Company has elected the short-term lease practical expedient; as such, the Company does not to recognize lease liabilities and ROU assets on operating leases with terms of one year or less. An ROU asset is measured based on the present value of the future minimum lease payments, adjusted for any initial direct costs, incentives, or other payments prior to the lease commencement date. A lease liability represents a legal obligation to make lease payments and is measured based on the present value of the future minimum lease payments. The Company utilizes the incremental borrowing rate, which is the rate of interest that would be incurred to borrow on a collateralized basis over a similar term on an amount equal to the lease payments in a similar economic environment since the interest rate implicit in the lease contract is typically not readily determinable. Variable lease payments that are dependent on either an index or rate are initially measured using the index or rate at the commencement date and included in the measurement of the lease liability. Renewal options are not included as part of the ROU asset or lease liability unless the renewal option is deemed reasonably certain to be exercised. ROU assets and operating lease liabilities are included in Premises and equipment and Accrued expenses and other liabilities, respectively, on the accompanying Consolidated Balance Sheets.

For real estate leases, lease components and non-lease components are accounted for as a single lease component. For equipment leases, lease components and non-lease components are accounted for separately. Operating lease expense, which is comprised of operating lease costs and variable lease costs, net of sublease income, is amortized on a straight-line basis and reflected as a part of Occupancy or Technology and equipment expense on the accompanying Consolidated Statements of Income. Additional information regarding the Company’s lessee arrangements can be found within Note 6: Leasing.

Goodwill

Goodwill represents the excess purchase price of businesses acquired over the fair value of the identifiable net assets acquired and is assigned to specific reporting units. Goodwill is not subject to amortization but rather is evaluated for impairment annually, or more frequently if events occur or circumstances change indicating it would more likely than not result in a reduction of the fair value of the reporting units below their carrying value, including goodwill.

87

Table of Contents

Goodwill may be evaluated for impairment by first performing a qualitative assessment. If the qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, including goodwill, or, if for any other reason the Company determines it to be appropriate, then a quantitative assessment will be performed. The quantitative assessment process utilizes an income and market approach to arrive at an indicated fair value range for the reporting units. The fair value calculated for each reporting unit is compared to its carrying amount, including goodwill, to ascertain if goodwill impairment exists. If the fair value exceeds the carrying amount, including goodwill for a reporting unit, it is not considered to be impaired. If the fair value is below the carrying amount, including goodwill for a reporting unit, then an impairment charge is recognized for the amount by which the carrying amount exceeds the calculated fair value, up to but not exceeding the amount of goodwill allocated to the reporting unit. The resulting amount is charged to Other expense on the accompanying Consolidated Statements of Income.

The Company completed a quantitative assessment for its reporting units during its most recent annual impairment review. Based on this quantitative assessment, the Company determined that there was no evidence of impairment to the balance of its goodwill. Additional information regarding goodwill can be found within Note 7: Goodwill and Other Intangible Assets.

Other Intangible Assets

Other intangible assets represent purchased assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights, or because they are capable of being sold or exchanged either separately or in combination with a related contract, asset, or liability. Other intangible assets with finite useful lives, such as core deposits and customer relationships, are amortized to non-interest expense over their estimated useful lives and are evaluated for impairment whenever events occur or circumstances change indicating that the carrying amount of the asset may not be recoverable. Recognized impairment losses are charged to Other expense on the accompanying Consolidated Statements of Income. Additional information regarding other intangible assets can be found within Note 7: Goodwill and Other Intangible Assets.

Cash Surrender Value of Life Insurance

Bank-owned life insurance represents the cash surrender value of life insurance policies on certain current and former employees of Webster and Sterling, and employees of banks that Webster and Sterling had previously acquired. Cash surrender value increases and decreases are recorded in Non-interest income. Death benefit proceeds in excess of the cash surrender value are recorded in Other income upon the death of the insured.

Revenue From Contracts With Customers

Revenue from contracts with customers comprises non-interest income earned in exchange for services provided to customers and is recognized either when services are completed or as they are rendered. These revenue streams include Deposit service fees, Wealth and investment services, and non-significant portions of Loan and lease related fees and Other income on the accompanying Consolidated Statements of Income. The Company identifies the performance obligations included in its contracts with customers, determines the transaction price, allocates the transaction price to the performance obligations, as applicable, and recognizes revenue when the performance obligations are satisfied. Services provided over a period of time are generally transferred to customers evenly over the term of the contracts, and revenue is recognized evenly over the period the services are provided. On the accompanying Consolidated Balance Sheets, deferred costs to obtain contracts are included in Accrued interest receivable and other assets, and deferred revenue is included in Accrued expenses and other liabilities. Payment terms vary by services offered, and generally the time between the completion of performance obligations and receipt of payment is not significant. Additional information regarding contracts with customers can be found within Note 21: Revenue from Contracts with Customers.

Stock-Based Compensation

The Company maintains a stock compensation plan that provides for the grant of stock options, stock appreciation rights, restricted stock, performance-based stock, and stock units to employees and directors. Share awards are issued from available treasury shares. Stock compensation expense is recognized over the required service vesting period for each award based on the grant date fair value, and is included within Compensation and benefits expense on the accompanying Consolidated Statements of Income. For time-based restricted stock awards and average return on equity performance-based restricted stock awards, fair value is measured using the closing price of Webster common stock at the grant date. For total stockholder return performance-based restricted stock awards, fair value is measured using the Monte Carlo simulation model. Performance-based restricted stock awards ultimately vest in a range from 0% to 150% of the target number of shares under the grant. Compensation expense may be subject to adjustment based on management’s assessment of the Company’s average return on equity performance relative to the target number of shares condition. Stock option awards use the Black-Scholes Option-Pricing Model to measure fair value at the grant date. Forfeiture of stock awards are accounted for as they occur. Excess tax benefits or tax deficiencies result when tax return deductions differ from recognized compensation cost determined using the grant-date fair value approach for financial statement purposes. Dividends are paid on time-based shares upon grant and are non-forfeitable, while dividends

are accrued on performance-based awards and are paid with the vested shares when the performance target is met. Additional information regarding share-based compensation can be found within Note 19: Stock-Based Compensation Plans.

Income Taxes

Income tax expense (benefit) is comprised of two components, current and deferred. The current component represents income taxes payable or refundable for the current period based on applicable tax laws, while the deferred component represents the tax effects of temporary differences between amounts recognized for financial accounting and tax purposes. DTAs and DTLs reflect the tax effects of such differences that are anticipated to result in taxable or deductible amounts in the future when the temporary differences reverse. DTAs are recognized if it is more likely than not that they will be realized, and may be reduced by a valuation allowance if it is more likely than not that all or some portion will not be realized.

Uncertain tax positions that meet a more likely than not recognition threshold are initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with a taxing authority based on knowledge of all relevant information. The determination of whether or not a tax position meets the more likely than not recognition threshold considers the facts, circumstances, and information available at the reporting date and is subject to management judgment. The Company recognizes interest and penalties on uncertain tax positions and interest on refundable income taxes as a component of Income tax expense and Other income, respectively, on the accompanying Consolidated Statements of Income. Additional information regarding income taxes can be found within Note 8: Income Taxes.

Earnings per Common Share

Earnings per common share is calculated under the two-class method. Basic earnings per common share is computed by dividing earnings applicable to common stockholders by the weighted-average number of common shares outstanding, excluding outstanding participating securities, during the pertinent period. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of shares resulting from stock compensation and warrants for common stock using the treasury stock method. The identification of the Company’s participating securities and a reconciliation between the weighted-average common shares used in calculating basic earnings per common share and the weighted-average common shares used in calculating diluted earnings per common share can be found within Note 15: Earnings Per Common Share.

Comprehensive Income (Loss)

Comprehensive income (loss) includes all changes in equity during the period, except those resulting from transactions with stockholders. Comprehensive income (loss) comprises net income and the after-tax effect changes in the following items: net unrealized gain (loss) on available-for-sale securities, net unrealized gain (loss) on derivative instruments, and net actuarial gain (loss) related to defined benefit pension and other postretirement benefit plans. Comprehensive income (loss) is reported on the accompanying Consolidated Statements of Stockholders’ Equity and the accompanying Consolidated Statements of Comprehensive Income. Income tax effects of these items are released from Comprehensive income (loss) contemporaneously with the related gross pretax amount. Additional information regarding comprehensive income (loss) can be found within
Note 12: Accumulated Other Comprehensive (Loss), Net of Tax.

Derivative Instruments and Hedging Activities

Derivatives are recognized at fair value and are included in Accrued interest receivable and other assets and Accrued expenses and other liabilities, as applicable, on the accompanying Consolidated Balance Sheets. The value of exchange-traded contracts is based on quoted market prices, whereas non-exchange traded contracts are valued based on dealer quotes, pricing models, discounted cash flow methodologies, or similar techniques in which the determination of fair value may require management judgment or estimation. Net cash flows from derivative contract assets and liabilities are presented within Operating activities on the accompanying Consolidated Statements of Cash Flows.

Derivatives Designated in Hedge Relationships. The Company uses derivatives to hedge exposures or to modify interest rate characteristics for certain balance sheet accounts under its interest rate risk management strategy. The Company designates derivatives in qualifying hedge relationships either as fair value or cash flow hedges for accounting purposes. Derivative financial instruments receive hedge accounting treatment if they are qualified and are properly designated as a hedge, and remain highly effective in offsetting changes in the fair value or cash flows attributable to the risk being hedged, both at hedge inception and on an ongoing basis throughout the life of the hedge. Quarterly prospective and retrospective assessments are performed to ensure hedging relationships continue to be highly effective. If a hedge relationship is no longer highly effective, hedge accounting would be discontinued.

89

Table of Contents

The change in fair value on a derivative that is designated and qualifies as a fair value hedge, as well as the offsetting change in fair value on the hedged item attributable to the risk being hedged, is recognized in earnings. The gain or loss on a derivative that is designated and qualifies as a cash flow hedge is initially recorded as a component of AOCL, and either subsequently reclassified to interest income as hedged interest payments are received or to interest expense as hedged interest payments are made during the same period in which the hedged transaction affects earnings.

Derivatives Not Designated in Hedge Relationships. The Company also enters into derivative transactions that are not designated in hedge relationships. Derivative financial instruments not designated in hedge relationships are recorded at fair value with changes in fair value recognized in Other income on the accompanying Consolidated Statements of Income.

Offsetting Assets and Liabilities. Derivative assets and derivative liabilities with the same counterparty are presented on a net basis in Accrued interest receivable and other assets or Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets when master netting agreements are in place. Cash collateral paid or received for non-exchange cleared transactions are presented net with the associated derivative assets and derivative liabilities. Securities collateral is not offset. Amounts paid to dealers for initial margin are also included in Accrued interest receivable and other assets. Additional information regarding derivatives can be found within Note 16: Derivative Financial Instruments.

Fair Value Measurements

The Company measures many of its assets and liabilities on a fair value basis in accordance with ASC Topic 820, Fair Value Measurement. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is used to measure certain assets and liabilities on a recurring basis when fair value is the primary basis of accounting, and on a non-recurring basis when evaluating assets or liabilities for impairment. Additional information regarding the Company’s policies and methodologies used to measure fair value can be found within Note 17: Fair Value Measurements.

Employee Retirement Benefit Plans

The Company sponsors defined contribution postretirement benefit plans that are established under Section 401(k) of the Internal Revenue Code. Expenses to maintain the plans, as well as employer contributions, are charged to Compensation and benefits on the accompanying Consolidated Statements of Income.

The Bank had offered a qualified noncontributory defined benefit pension plan and a non-qualified SERP to eligible employees and key executives who met certain age and service requirements, both of which were frozen effective December 31, 2007. The Bank also provides for OPEB to certain retired employees. In connection with the merger with Sterling, the Company also assumed the benefit obligations of Sterling’s non-qualified SERP and OPEB plans.

Pension contributions are funded in accordance with the requirements of the Employee Retirement Income Security Act. Net periodic benefit cost (income), which is based upon actuarial computations of current and future benefits for eligible employees, are charged to Other expense on the accompanying Consolidated Statements of Income. The funded status of the plans is recorded as an asset when over-funded or a liability when under-funded. Additional information regarding the defined benefit pension and postretirement benefit plans can be found within Note 18: Retirement Benefit Plans.

Accounting Standards Adopted During the Current Year

ASU No. 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures

In December 2023, the FASB issued ASU No. 2023-09—Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to provide more transparency about income tax information through improvements to income tax disclosures, primarily related to the rate reconciliation and income taxes paid information. Specifically, the amendments in this Update require disclosure of: (i) a tabular reconciliation, using both percentages and reporting currency amounts, with prescribed categories that are required to be disclosed, and the separate disclosure and disaggregation of prescribed reconciling items with an effect equal to 5% or more of the amount determined by multiplying pretax income from continuing operations by the application statutory rate; (ii) a qualitative description of the states and local jurisdictions that make up the majority (greater than 50%) of the effect of the state and local income taxes; and (iii) amount of income taxes paid, net of refunds received, disaggregated by federal, state, and foreign taxes and by individual jurisdictions that comprise 5% or more of total income taxes paid, net of refunds received. The amendments in this Update also include certain other amendments to improve the effectiveness of income tax disclosures.

The Company adopted the Update as of December 31, 2025, on a retrospective basis. Refer to the section captioned “Disaggregation of Income Taxes Paid” earlier in this Note 1: Summary of Significant Accounting Policies and Note 8: Income Taxes for the incorporation of such additional income tax disclosure information.

Relevant Accounting Standards Issued But Not Yet Adopted

ASU No. 2024-03—Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures
(Subtopic 220-40): Disaggregation of Income Statement Expenses

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires entities to disclose specified information about certain costs and expenses in the notes to financial statements at each interim and annual reporting period, including the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depletion included in each relevant expense caption. For the employee compensation category, bank holding companies may continue to present compensation expense on the face of the income statement in accordance with Regulation S-X Rule 210.9-04. A qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively are also required to be disclosed. In addition, entities must disclose the total amount of selling expenses and, in annual reporting periods, their definition of selling expenses.

The Update is effective for annual periods beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments may be applied on either a prospective or retrospective basis. The Company is currently evaluating this guidance to determine the impact on its non-interest expense disclosures; however, the impact is not expected to be material.

ASU No. 2025-06—Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software

In September 2025, the FASB issued ASU No. 2025-06—Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, to modernize the accounting framework for internal-use software development. The amendments eliminate the requirement to evaluate software development stages and instead introduce a principles-based capitalization threshold. Under the new guidance, entities begin capitalizing costs when (i) management authorizes and commits to funding the project, and (ii) it is probable the project will be completed, and the software will be used to perform its intended function (the “probable-to-complete” threshold).

The Update is effective for annual periods beginning after December 15, 2027, including interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments may be applied using either a prospective, modified, or retrospective transition approach. The Company is currently evaluating this guidance to determine the impact on its internal-use software costs capitalization policy and financial statement presentation.

ASU No. 2025-08—Financial Instruments—Credit Losses (Topic 326): Purchased Loans

In November 2025, the FASB issued ASU No. 2025‑08, Financial Instruments—Credit Losses (Topic 326): Purchased Loans, which expands the gross‑up approach under CECL beyond PCD assets to include certain purchased seasoned loans. Under the amendments, loans (excluding credit cards) acquired without credit deterioration and deemed “seasoned,” as defined in the Update, are considered purchased seasoned loans and accounted for using the gross-up approach at acquisition. The Update also clarifies that any difference between the unpaid principal balance and the grossed-up basis is a non-credit discount or premium, which is to be accreted or amortized into interest income over the term of the loan.

The Update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The amendments are to be applied prospectively. The Company is currently evaluating this guidance to determine the impact on its consolidated financial statements.

ASU No. 2025-09—Derivatives and Hedging (Topic 815): Hedge Accounting Improvements

In November 2025, the FASB issued ASU No. 2025‑09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements, which introduces targeted refinements to simplify and expand hedge accounting. The amendments (i) permit designation of groups of forecasted transactions with similar risk exposure in a cash flow hedge, (ii) provide an optional model for hedging choose‑your‑rate debt instruments to maintain continuity when contractual terms allow index or tenor changes, (iii) allow designation of variable price components of forecasted purchases or sales of nonfinancial items, and (iv) remove the presumption that a derivative instrument that results from combining a written option and any other non-option derivative are automatically a written option. The Update also eliminates presentation mismatches for dual hedge strategies involving foreign‑currency‑denominated debt.

The Update is effective for annual periods beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The amendments are to be applied prospectively. The Company is currently evaluating this guidance to determine the impact on its consolidated financial statements.

Note 2: Business Developments

SecureSave Acquisition

On December 4, 2025, the Company acquired SecureSave, a financial technology company that partners with employers to offer employees FDIC-insured emergency savings accounts funded through automatic payroll deductions to help budget for unexpected expenses. The acquisition provided the Company with a new source of low-cost deposits with potential for growth, access to SecureSave’s existing client partnerships, and enhanced the Company’s financial wellness offerings.

Prior to the acquisition, the Company had a 17% interest in SecureSave. Upon acquisition, the Company remeasured its previously held equity interest in SecureSave to its acquisition-date fair value of $8.0 million, and recognized an insignificant loss in Other income on the accompanying Consolidated Statement of Income.

The total consideration transferred was $34.9 million, which reflects the purchase price for the remaining 83% of the business, and included cash paid at closing of $26.5 million and contingent consideration with an acquisition-date fair value of $8.4 million. The contingent consideration is payable in cash up to a maximum $35.0 million, based upon the achievement of deposit growth performance targets at three consecutive annual measurement dates beginning December 31, 2026. Additional information regarding the determination of fair value for contingent consideration liabilities can be found within Note 17: Fair Value Measurements.

The acquisition was accounted for as a business combination. The total consideration transferred was preliminarily allocated to $13.5 million of net identifiable assets acquired, measured at fair value, which primarily comprised a $7.6 million core deposit intangible asset and a $1.9 million non-competition agreement intangible asset. The associated core deposit intangible asset is being amortized on an accelerated basis over an estimated useful life of 10 years, which represents the period over which the expected economic benefits are anticipated to be received. The non-competition agreement intangible asset is being amortized on a straight-line basis over an estimated useful life of 3 years. The Company considers its valuations of other intangible assets and, in turn, the related deferred tax impact, to be provisional at December 31, 2025.

The $29.5 million of preliminary goodwill recognized, which represents the future economic benefits arising from acquiring SecureSave primarily due to expected synergies, is not deductible for tax purposes. Information regarding the allocation of goodwill to the Company’s reportable segments can be found within Note 20: Segment Reporting.

United Community Bank HSA Portfolio Acquisition

On November 14, 2025, the Company acquired a portfolio of HSAs from United Community Bank. The transaction was accounted for as an asset acquisition, and the Company received $10.5 million in both cash and deposits on the acquisition date. The Company also paid an 8% deposit premium based on the final settlement of deposits, which resulted in the recognition of an $0.8 million core deposit intangible asset. The associated core deposit intangible asset is being amortized over an estimated useful life of 9 years using a 1.5% declining balance approach. This portfolio acquisition reflects a planned change in custody related to the Company’s acquisition of Bend in 2022. The HSA deposits acquired in the transaction had been previously reflected as assets under administration, which are excluded from the Company’s Consolidated Balance Sheets.

Elements Financial Federal Credit Union HSA Portfolio Acquisition

On October 1, 2025, the Company acquired a portfolio of HSAs from Elements Financial Federal Credit Union. The transaction was accounted for as an asset acquisition, and the Company received $53.9 million in both cash and deposits on the acquisition date. The Company also paid a 12% deposit premium based on $40.9 million of the total deposits settlement, which resulted in the recognition of a $4.9 million core deposit intangible asset. The associated core deposit intangible asset is being amortized over an estimated useful life of 9 years using a 1.5% declining balance approach. This portfolio acquisition reflects a planned change in custody related to the Company’s acquisition of Bend in 2022. The HSA deposits acquired in the transaction had been previously reflected as assets under administration, which are excluded from the Company’s Consolidated Balance Sheets.

Allegacy Federal Credit Union HSA Portfolio Acquisition

On August 29, 2025, the Company acquired a portfolio of HSAs from Allegacy Federal Credit Union. The transaction was accounted for as an asset acquisition, and the Company received $6.2 million in both cash and deposits on the acquisition date. The Company also paid a 12% deposit premium based on the final settlement of deposits, which resulted in the recognition of a $0.7 million core deposit intangible asset. The associated core deposit intangible asset is being amortized over an estimated useful life of 9 years using a 1.5% declining balance approach. This portfolio acquisition reflects a planned change in custody related to the Company’s acquisition of Bend in 2022. The HSA deposits acquired in the transaction had been previously reflected as assets under administration, which are excluded from the Company’s Consolidated Balance Sheets.

Ametros Acquisition

On January 24, 2024, the Bank acquired all of the equity interest in Ametros from Long Ridge Capital Management (the “Seller”). Ametros is a custodian and administrator of medical funds from insurance claim settlements that helps individuals manage their ongoing medical care through its CareGuard service and proprietary technology platform. The acquisition provided the Bank with a fast-growing source of low-cost and long-duration deposits, new sources of non-interest income, and enhanced its employee benefit and healthcare financial services expertise.

The acquisition was accounted for as a business combination. Accordingly, the total purchase price, which included cash paid of $359.7 million, the forgiveness of $12.9 million in long-term debt, and the assumption of a $5.8 million liability for the Seller’s transaction expenses, has been allocated to the identifiable assets acquired and liabilities assumed based on their acquisition-date fair values, as summarized in the following table:

(In thousands)			Fair Value
Purchase price consideration			$	378,424
Assets:
Cash and due from banks			310
Premises and equipment			1,078
Other intangible assets			188,900
Deferred tax assets, net			(35,889)
Other assets:
Funds held in escrow			288,167
Accounts receivable			2,435
Prepaid expenses			1,166
Total other assets			291,768
Total assets acquired			$	446,167
Liabilities:
Interest-bearing deposits (1)			(20,622)
Other liabilities:
Accounts payable			684
Accrued expenses			4,270
Deferred revenue			20,391
Members’ funds			288,167
Operating lease liabilities			$	838
Total other liabilities			$	314,350
Total liabilities assumed			$	293,728
Net assets acquired			152,439
Pre-existing equity interest (2)			2,200
Goodwill			$	228,185

(1)The $20.6 million reflects the amount held in Ametros’ operating cash account at the Bank on January 24, 2024. Upon acquisition, such cash and the Bank’s corresponding deposit liability owed to Ametros were eliminated in consolidation, which resulted in a decrease to interest-bearing deposits for the Bank and the Bank’s legal title to the funds being held in such operating cash account.

(2)Prior to the acquisition date, the Company had a 0.6% equity interest in Ametros. The consideration transferred reflects the purchase price for the remaining 99.4% of the business. Upon acquisition, the Company recognized a $1.5 million gain in Other income on the accompanying Consolidated Statement of Income, which represents the difference between the cost basis and estimated acquisition-date fair value of the Company’s pre-existing equity interest in Ametros.

The Company’s valuations of the assets acquired and liabilities assumed in the Ametros acquisition were considered final as of December 31, 2024. There were no adjustments to fair value estimates recognized during the measurement period. The $228.2 million of goodwill represents future economic benefits arising from acquiring Ametros, primarily due to its strong market position and its assembled workforce, and is not deductible for tax purposes. Information regarding the allocation of goodwill to the Company’s reportable segments can be found within Note 20: Segment Reporting.

The Company incurred $3.1 million of professional and outside services expenses related to the acquisition of Ametros during the first quarter of 2024. The revenue and earnings related to the Ametros business since the acquisition date are included in the Company’s Consolidated Statements of Income for the years ended December 31, 2025, and 2024, and were not material.

93

Table of Contents

The following is a description of the valuation methodologies used to estimate the fair values of the significant assets acquired and liabilities assumed:

Other intangible assets. The Company identified and recognized a $182.8 million core deposit intangible asset and a
$6.1 million trade name intangible asset. A core deposit intangible asset represents the value of relationships with deposit customers. The fair value of the core deposit intangible asset was estimated using a net cost savings method, a form of discounted cash flow methodology, which gave appropriate consideration to expected client attrition rates and other applicable adjustments to the projected deposit balance, the interest cost and net maintenance cost associated with the client deposit base, an alternative cost of funds, and a discount rate that was used to discount the future economic benefits of the core deposit intangible asset to present value. The core deposit intangible asset is being amortized on an accelerated basis over an estimated useful life of 25 years, which is the period over which the estimated economic benefits are estimated to be received. The fair value of the trade name intangible asset for the Ametros brand was estimated using a relief-from-royalty methodology, which models the cost savings from owning the brand rather than licensing it from a third party. The trade name intangible asset is being amortized on a straight-line basis over an estimated useful life of 5 years.

Funds held in escrow and Members’ funds. Funds held in escrow represent amounts held in interest-bearing checking accounts at insured depository institutions other than the Bank for the purpose of providing post-settlement medical administration services on a respective member’s behalf. Members’ funds is the corresponding liability to the Funds held in escrow. Given that these amounts can be withdrawn and/or directed for use on demand, as long as in accordance with the terms of the settlement agreement, their carrying amount is a reasonable estimate of fair value.

Joint Venture with Marathon Asset Management

On July 19, 2024, the Company, through its subsidiary, MW Advisor Holding, LLC, entered into an agreement with Marathon Asset Management and formed a private credit joint venture, which is designed to deliver direct lending solutions for sponsor-backed middle market companies across the country.

During the year ended December 31, 2025, the Company identified and sold $247.5 million, in aggregate, of commercial non-mortgage loans comprising the seed portfolio to launch the joint venture’s operations. The transfers each met the requisite criteria to be accounted for as sales in accordance with ASC 860, Transfers and Servicing. The resulting gain on sale of $2.1 million, in aggregate, was included in Other income on the accompanying Consolidated Statements of Income and in Commercial Banking for segment reporting purposes. Upon the identification of the loans to be sold, the $1.3 million difference, in aggregate, between the lower of the amortized cost basis of the loans and their fair value was charged-off and recognized in the Provision for credit losses on the accompanying Consolidated Statements of Income.

Multi-family Securitization

On September 30, 2024, the Company completed a multi-family securitization, in which it transferred $303.9 million of multi-family loans ($302.5 million carrying amount plus $1.4 million accrued interest receivable) to a third-party depositor, who placed the multi-family loans into a third-party trust, in exchange for net cash proceeds of $311.6 million. Through a two-step process, pass-through certificates were issued, which are secured by the multi-family loans and guaranteed by Freddie Mac. The transfer of the multi-family loans was accounted for as a sale in accordance with ASC 860, Transfers and Servicing. Servicing rights were not retained.

Per the terms of the securitization agreement, the Company assumed an obligation to reimburse Freddie Mac for any payments made under Freddie Mac’s guarantee of the certificates. The reimbursement obligation covers losses up to 12% of the aggregate UPB of the multi-family loans at the time of sale, and is secured in full by an irrevocable letter of credit issued by the FHLB. Essentially, this reimbursement obligation represents a first credit loss enhancement provided by the Company to Freddie Mac. Based on the credit quality of the multi-family loans at the time of sale, among other factors, the Company estimated the fair value of its reimbursement obligation to be $3.3 million. Including the reimbursement obligation, the transaction resulted in a net gain on sale of $4.4 million. The carrying amount of the reimbursement obligation remained at $3.3 million at both December 31, 2025, and 2024, and is included in Accrued expenses and other liabilities on the Consolidated Balance Sheets. The Company has not yet been required to make any guarantee payments to Freddie Mac.

Until the Company’s obligation to reimburse Freddie Mac for the first 12% of losses is reduced to 25% of the initial amount, it may have the option to exercise certain contingent repurchase rights over the transferred multi-family loans, unless it elects to waive or assign those rights. At both the time of sale, and as of December 31, 2025, the Company does not intend to repurchase any of the multi-family loans.

Payroll Finance Portfolio and Sale of Factored Receivables Portfolio

In March 2024, the Company initiated a plan to actively sell its payroll finance and factored receivables loan portfolios, along with the related customer contracts. This decision was a direct result of the Company’s continuous reassessment of its strategic model in an effort to identify opportunities to improve its core financial products and services. Accordingly, the aggregate $220.2 million balance of the payroll finance and factored receivables loans, at March 31, 2024, was reclassified and transferred from held for investment to held for sale on the accompanying Consolidated Balance Sheets. Upon the transfer, the $5.4 million ACL that was previously recorded against the payroll finance and factored receivables loans was reversed into earnings.

On September 27, 2024, the Company sold its factored receivables loan portfolio of $124.1 million, and the related customer contracts, for proceeds of $129.2 million. After the write-off of the factored receivables customer relationship intangible asset, which had a net carrying amount of $19.7 million, less $1.3 million of selling costs, the sale of assets resulted in a $16.0 million net loss on sale. The entire net loss is included in Other income on the Consolidated Statements of Income and in the Corporate and Reconciling category for segment reporting purposes in accordance with the Company’s methodology.

In December 2024, after re-evaluating its strategic priorities as part of its annual budgeting and forecasting process, the Company decided to terminate the plan of sale of its payroll finance portfolio and instead hold the loans as an investment for the foreseeable future. Accordingly, the $133.2 million balance of the payroll finance loans, at December 31, 2024, was reclassified and transferred from held for sale to held for investment on the accompanying Consolidated Balance Sheets. Upon the transfer, a $0.3 million ACL was re-established against the payroll finance loans.

Sale of Mortgage Servicing Rights

During the year ended December 31, 2023, the Company committed to and initiated a plan to actively market and sell the majority of its mortgage servicing portfolio. Upon making this determination, the Company treated the related mortgage servicing rights as assets held for disposition and ceased the recognition of any future amortization expense. On February 12, 2024, the Company sold the majority of its mortgage servicing portfolio, which comprised 9,184 individual residential mortgage loans with an aggregate UPB of $1.4 billion. In connection with the sale, the Company received net cash proceeds of $18.4 million and derecognized $6.7 million of mortgage servicing rights. The resulting $11.7 million net gain on sale of mortgage servicing rights is included in Other income on the Consolidated Statements of Income and in Consumer Banking for segment reporting purposes.

The $176.9 million decrease in gross unrealized losses of available-for-sale securities from December 31, 2024, to December 31, 2025, is primarily due to lower market interest rates and lower securities’ spreads. The Company assesses each available-for-sale security that is in an unrealized loss position on a quarterly basis to determine whether the decline in fair value below the amortized cost basis is a result of any credit related factors. There was no ACL recorded on available-for-sale securities at December 31, 2025. At December 31, 2024, the ACL on available-for-sale securities was $0.9 million, which related to a single Corporate debt security. Each of the Company’s available-for-sale securities in an unrealized loss position at December 31, 2025, is investment grade, current as to principal and interest, and their price changes are consistent with interest and credit spreads when adjusting for duration, convexity, rating, and industry differences.

Based on current market conditions and the Company’s targeted balance sheet composition strategy, the Company intends to hold its available-for-sale securities in unrealized loss positions through the anticipated recovery period. The issuers of these available-for-sale securities have not, to the Company’s knowledge, established any cause for default. Market prices are expected to approach par as the securities approach maturity.

Contractual Maturities

The following table summarizes the amortized cost and fair value of available-for-sale securities by contractual maturity:

			December 31, 2025
(In thousands)			Amortized Cost						Fair Value
Maturing within 1 year			$	12,514					$	12,495
After 1 year through 5 years			269,131						265,399
After 5 years through 10 years			880,536						851,880
After 10 years			9,304,797						8,879,726
Total available-for-sale			$	10,466,978					$	10,009,500

Available-for-sale securities that are not due at a single maturity date have been categorized based on the maturity date of the underlying collateral. Actual principal cash flows may differ from this categorization as borrowers have the right to prepay their obligations with or without prepayment penalties.

An ACL on held-to-maturity securities is recorded for certain Municipal bonds and notes to account for expected lifetime credit losses. Agency securities represent obligations issued by a U.S. government-sponsored enterprise or other federally related entity and are either explicitly or implicitly guaranteed, and therefore, assumed to be zero loss. Held-to-maturity securities with gross unrealized losses and no ACL are considered to be high credit quality, and therefore, zero credit loss has been recorded.

The following table summarizes the activity in the ACL on held-to-maturity securities:

Credit Quality Information

The Company monitors the credit quality of held-to-maturity securities through credit ratings provided by S&P, Moody’s, Fitch Ratings, Inc., Kroll Bond Rating Agency, or DBRS Inc. Credit ratings express opinions about the credit quality of a security and are updated at each quarter end. Investment grade securities are rated BBB- or higher by S&P, or Baa3 or higher by Moody’s, and are generally considered by the rating agencies and market participants to be of low credit risk. Conversely, securities rated below investment grade, which are labeled as speculative grade by the rating agencies, are considered to have distinctively higher credit risk than investment grade securities. At December 31, 2025, and 2024, there were no speculative grade held-to-maturity securities. Held-to-maturity securities that are not rated are collateralized with U.S. Treasury obligations.

The following tables summarize the amortized cost of held-to-maturity securities based on their lowest publicly available credit rating:

(1)The $29.8 million increase in the ACL on loans and leases from December 31, 2024, to December 31, 2025, is primarily due to additional reserves resulting from changes in the macroeconomic forecast, economic uncertainty, and loan growth, partially offset by net charge-offs, improvements in risk rating migration, and changes in commercial portfolio mix.

Concentrations of Credit Risk

Concentrations of credit risk may exist when a number of borrowers are engaged in similar activities, or activities in the same geographic region, and have similar economic characteristics that would cause them to be similarly impacted by changes in economic or other conditions. Concentrations of credit risk are controlled and monitored as part of the Company’s credit policies and procedures. The Company is a regional financial services holding company in the Northeast U.S. with a commercial concentration primarily in five geographic markets: New York City, Other New York Counties, Connecticut, New Jersey, and Massachusetts; and secondarily in the Southeast and Other states. At December 31, 2025, and 2024, the Company’s concentration of credit risk associated with commercial real estate and multi-family loans, in aggregate, represented 39.5% and 40.7% of total loans and leases, respectively. At December 31, 2025, and 2024, the Company’s concentration of credit risk associated with commercial non-mortage loans represented 36.0% and 34.4% of total loans and leases, respectively.

Credit Quality Indicators

To measure credit risk for the commercial portfolio, the Company employs a dual grade credit risk grading system for estimating the PD and LGD. The credit risk grade system assigns a rating to each borrower and to the facility, which together form a Composite Credit Risk Profile. The credit risk grade system categorizes borrowers by common financial characteristics that measure the credit strength of borrowers and facilities by common structural characteristics. The Composite Credit Risk Profile has ten grades, with each grade corresponding to a progressively greater risk of loss. Grades (1) to (6) are considered pass ratings, and grades (7) to (10) are considered criticized, as defined by the regulatory agencies. A (7) “Special Mention” rating has a potential weakness that, if left uncorrected, may result in deterioration of the repayment prospects for the asset. An (8) “Substandard” rating has a well-defined weakness that jeopardizes the full repayment of the debt. A (9) “Doubtful” rating has all of the same weaknesses as a substandard asset with the added characteristic that the weakness makes collection or liquidation in full, given current facts, conditions, and values, improbable. Assets classified as a (10) “Loss” rating are considered uncollectible and charged-off. Risk ratings, which are assigned to differentiate risk within the portfolio, are reviewed on an ongoing basis and revised to reflect changes in a borrower’s current financial position and outlook, risk profile, and the related collateral and structural position. Loan officers review updated financial information or other loan factors on at least an annual basis for all pass rated loans to assess the accuracy of the risk grade. Criticized loans undergo more frequent reviews and enhanced monitoring.

To measure credit risk for the consumer portfolio, the most relevant credit characteristic is the FICO score, which is a widely used credit scoring system that ranges from 300 to 850. A lower FICO score is indicative of higher credit risk and a higher FICO score is indicative of lower credit risk. FICO scores are updated at least quarterly. Factors such as past due status, employment status, collateral, geography, loans discharged in bankruptcy, and the status of first lien position loans on second lien position loans, are also considered to be consumer portfolio credit quality indicators. For portfolio monitoring purposes, the Company estimates the current value of property secured as collateral for home equity and residential first mortgage lending products on an ongoing basis. The estimate is based on home price indices compiled by the S&P/Case-Shiller Home Price Indices. Real estate price data is applied to the loan portfolios taking into account the age of the most recent valuation and geographic area.

Collateral Dependent Loans and Leases

A non-accrual loan or lease is considered collateral dependent when the borrower is experiencing financial difficulty and when repayment is substantially expected to be provided through the operation or sale of collateral. Commercial non-mortgage loans,
asset-based loans, and equipment financing loans and leases are generally secured by machinery and equipment, inventory, receivables, or other non-real estate assets, whereas commercial real estate, multi-family, residential, and home equity loans are secured by real estate.

At December 31, 2025, and 2024, the carrying amount of collateral dependent loans was $308.3 million and $139.5 million, respectively, for commercial loans and leases, and $28.1 million and $29.1 million, respectively, for consumer loans. The ACL for collateral dependent loans and leases is individually assessed based on the fair value of the collateral less costs to sell at the reporting date. At December 31, 2025, and 2024, the aggregate collateral value associated with collateral dependent loans and leases was $364.3 million and $200.1 million, respectively.

Modifications to Borrowers Experiencing Financial Difficulty

In certain circumstances, the Company enters into agreements to modify the terms of loans to borrowers experiencing financial difficulty. A variety of solutions are offered to borrowers experiencing financial difficulty, including loan modifications that may result in principal forgiveness, interest rate reductions, payment delays, term extensions, or a combination thereof. The following is a description of each of these types of modifications:

•Principal forgiveness – The outstanding principal balance of a loan may be reduced by a specified amount. Principal forgiveness may occur voluntarily as part of a negotiated agreement with a borrower, or involuntarily through a bankruptcy proceeding.

•Interest rate reductions – Includes modifications where the contractual interest rate of the loan has been reduced.

•Payment delays – Deferral arrangements that allow borrowers to delay a scheduled loan payment to a later date. Deferred loan payments do not affect the original contractual maturity terms of the loan. Modifications that result in only an insignificant payment delay are not disclosed. The Company generally considers a payment delay of three months or less to be insignificant.

•Term extensions – Extensions of the original contractual maturity date of the loan.

•Combination – Combination includes loans that have undergone more than one of the above loan modification types.

Significant judgment is required to determine if a borrower is experiencing financial difficulty. These considerations vary by portfolio class. The Company has identified modifications to borrowers experiencing financial difficulty that are included in its disclosures as follows:

•Commercial: The Company evaluates modifications of loans to commercial borrowers that are rated substandard or worse, and includes the modifications in its disclosures to the extent that the modification is considered
other-than-insignificant.

•Consumer: The Company generally evaluates all modifications of loans to consumer borrowers subject to its loss mitigation program and includes them in its disclosures to the extent that the modification is considered other-than-insignificant.

The following tables summarize the amortized cost basis at December 31, 2025, 2024, and 2023, of loans modified to borrowers experiencing financial difficulty, disaggregated by class and type of concession granted:

Income tax expense			$	257,347					$	248,300					$	216,664

The deferred federal expense in 2025 reflects the effects of accelerated deductions the Company plans to take on its 2025 federal tax return as afforded by the One Big Beautiful Bill Act. Deferred SALT expense was not impacted by those deductions to any significant degree, while deferred SALT expense in 2025 does include a $5.5 million benefit from operating loss carryforwards. The Company’s total deferred tax expense in 2024 included $29.4 million related to an increase in its valuation allowance for its SALT DTAs attributable to operating loss carryforwards.

The following table reflects a reconciliation of reported income tax expense to the amount that would result from applying the federal statutory rate of 21.0%:

The Company’s net DTAs decreased by $121.1 million during 2025, reflecting primarily the $47.6 million deferred tax expense and a $76.5 million expense allocated directly to AOCL, partially offset by a $3.8 million net DTA recognized as part of purchase accounting adjustments related to the acquisition of SecureSave.

The valuation allowance of $56.8 million at December 31, 2025, is attributable to SALT net operating loss and credit carryforwards, as compared to $64.4 million at December 31, 2024, which was comprised of $62.7 million attributable to SALT net operating loss and credit carryforwards and $1.7 million of capital loss carryforwards. The $7.6 million decrease in the valuation allowance during 2025 primarily reflects a $7.3 million expiration of net operating loss carryforwards for which a valuation allowance existed at December 31, 2024.

SALT net operating loss carryforwards of approximately $1.1 billion and SALT credit carryforwards of $1.1 million at December 31, 2025, have varying carryforward periods. The vast majority of the SALT net operating loss and credit carryforwards are scheduled to expire during the years 2026 through 2032. Federal net operating loss carryforwards of approximately $31.3 million and federal credit carryforwards of $0.5 million at December 31, 2025, related to the Bend and SecureSave acquisitions are subject to annual limitations on utilization, with the net operating losses able to be carried forward indefinitely and the credits scheduled to expire in varying amounts between 2038 and 2045. The valuation allowance reflects approximately $1.0 billion of those SALT net operating loss carryforwards and $0.5 million of the SALT credit carryforwards that are estimated to expire unused.

Management believes it is more likely than not that the results of future operations will generate sufficient taxable income to realize its total DTAs, net of the valuation allowance. Although taxable income in prior years is no longer able to be included as a source of taxable income, due to the general repeal of the carryback of net operating losses under the Tax Cuts and Jobs Act of 2017, significant positive evidence remains in support of management’s conclusion regarding the realizability of the Company’s DTAs, including projected future reversals of existing taxable temporary differences and book-taxable income levels in recent years and projected in future years. There can, however, be no assurance that any specific level of future income will be generated or that the Company’s DTAs will ultimately be realized.

DTLs of $63.2 million at both December 31, 2025, and 2024, have not been recognized for certain thrift bad-debt reserves, established before 1988, that would become taxable upon the occurrence of certain events: distributions by the Bank in excess of certain earnings and profits; the redemption of the Bank’s stock; or liquidation. The Company does not expect any of those events to occur.

The Company recognizes interest and penalties related to UTBs, where applicable, in income tax expense. The Company recognized a benefit of $1.6 million during the year ended December 31, 2025, and expenses of $3.1 million, and $1.8 million during the years ended December 31, 2024, and 2023, respectively. At December 31, 2025, and 2024, the Company had accrued interest and penalties related to UTBs of $5.3 million and $6.9 million, respectively.

The Company’s federal tax returns for years subsequent to 2021 remain open to examination, except for the carryback of a Sterling 2019 net operating loss under the CARES Act in 2020 to tax years 2014 and 2016, which is currently under audit by the Internal Revenue Service. The Company's tax returns filed in its other principal tax jurisdictions of Connecticut, New York State, New York City, Massachusetts and New Jersey, are either under or remain open to examination for varying years subsequent to 2016, 2018, or 2021.

Securities sold under agreements to repurchase and federal funds purchased (2)			$	596,738		3.32		%				$	344,168		2.98		%

(1)Securities sold under agreements to repurchase have an original maturity date of one year or less for the periods presented.

(2)There were no outstanding federal funds purchased at December 31, 2025, and 2024.

The Company’s repurchase agreement counterparties are limited to primary dealers in government securities and commercial and municipal customers through the Corporate Treasury function. The Company has the right of offset with respect to repurchase agreement assets and liabilities with the same counterparty when master netting agreements are in place. Securities sold under agreements to repurchase are presented as gross transactions at December 31, 2025, and 2024, since only liabilities are outstanding. Agency MBS securities, which had an aggregate carrying value of $625.3 million and $358.4 million at December 31, 2025, and 2024, respectively, are pledged to secure repurchase agreements. These Agency MBS securities are subject to changes in market value and, therefore, the Company may increase or decrease the level of securities pledged as collateral based upon movements in market value.

The following tables represent the offsetting of repurchase agreements that are subject to master netting agreements:

			December 31, 2025
			Gross Amounts of Recognized Liabilities						Gross Amounts Offset in the Statement of Financial Position						Net Amounts of Liabilities Presented in the Statement of Financial Position						Gross Amounts Not Offset in the Statement of Financial position

The terms of the Series F Preferred Stock prohibit the Company from declaring or paying any cash dividends on Webster common stock, and from repurchasing, redeeming, or otherwise acquiring Webster common stock or any other series of Webster preferred stock to which it ranks on parity with, unless dividends have been declared and paid in full on the Series F Preferred Stock for the most recent dividend period.

The Series F Preferred Stock is perpetual and has no maturity date, and is not subject to any mandatory redemption, sinking fund, or other similar provisions.

Note 13: Regulatory Capital and Restrictions

Regulatory Capital Requirements

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory actions by regulators that could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and/or the regulatory framework for prompt corrective action (applies to the Bank only), both the Company and the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated pursuant to regulatory directives. Capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.

Quantitative measures established by Basel III to ensure capital adequacy require the Company and the Bank to maintain minimum ratios of CET1 Risk-Based Capital, Risk-Based Capital, Total Risk-Based Capital, and Tier 1 Leverage Ratio, as defined in the regulations. CET1 capital consists of common stockholders’ equity, less deductions for goodwill and other intangible assets, and certain deferred tax adjustments. At the time of initial adoption of the Basel III Capital Rules, the Company had elected to opt-out of the requirement to include certain components of AOCI in CET1 capital. Tier 1 capital consists of CET1 capital plus preferred stock. Total capital consists of Tier 1 capital and Tier 2 capital, as defined in the regulations. Tier 2 capital includes qualifying subordinated debt and the permissible portion of the ACL.

At December 31, 2025, and 2024, both the Company and the Bank were classified as “well-capitalized.”

The following table provides information on the regulatory capital ratios for the Company and the Bank:

(1)In accordance with regulatory capital rules, the Company elected to delay the estimated impact of the adoption of CECL on its regulatory capital over a two-year deferral period, which ended on January 1, 2022, and a subsequent three-year transition period, which ended on December 31, 2024. During the three-year transition period, regulatory capital ratios phased out the aggregate amount of the regulatory capital benefit provided from the delayed CECL adoption in the initial two years. For 2024, the Company was allowed 25%, of the regulatory capital benefit as of December 31, 2021. Full absorption occurred in 2025.

Table of Contents

Dividend Restrictions

The Company is dependent upon dividends from the Bank to provide funds for the payment of dividends to stockholders and for other cash requirements. Dividends paid by the Bank are subject to various federal and state regulatory limitations. Express approval by the OCC is required if the effect of dividends declared would cause the regulatory capital of the Bank to fall below specified minimum levels or if the amount would exceed net income for that year combined with undistributed net income for the preceding two years. During the years ended December 31, 2025, and 2024, the Bank paid the Company $900.0 million and $600.0 million in dividends, respectively, for which no express approval from the OCC was required.

Cash Restrictions

The Bank is required under Federal Reserve regulations to maintain cash reserve balances in the form of vault cash or deposits held at a FRB to ensure that it is able to meet customer demands. The reserve requirement ratio is subject to adjustment as economic conditions warrant. On March 26, 2020, the Federal Reserve reduced the reserve requirement ratios on all net transaction accounts to zero percent. As a result, the Bank has not been required to hold cash reserve balances since that date.

Note 14: Variable Interest Entities

The Company has an investment interest in the following entities that each meet the definition of a VIE. Information regarding the consolidation of VIEs can be found within Note 1: Summary of Significant Accounting Policies.

Consolidated

Rabbi Trusts. The Company had established a Rabbi Trust to meet its obligations due under the Webster Bank Deferred Compensation Plan for Directors and Officers. The funding of this Rabbi Trust and the discontinuation of the Webster Bank Deferred Compensation Plan for Directors and Officers occurred during 2012. In 2025, the Company amended the Rabbi Trust that had been established for the Webster Bank Deferred Compensation Plan for Directors and Officers to also cover the funding of its obligations due under the Webster Bank Deferred Director Fee Plan. Further, in connection with the merger with Sterling in 2022, the Company acquired assets held in separate Rabbi Trusts that had been respectively established to fund obligations due under the Greater New York Savings Bank Directors’ Retirement Plan and the Sterling National Bank Nonqualified Deferred Compensation Plan (renamed as the Webster Bank Nonqualified Deferred Compensation Plan).

The Company is considered the primary beneficiary of these Rabbi Trusts as it has the power to direct the activities that most significantly impact their economic performance and it has the obligation to absorb losses and/or the right to receive benefits that could potentially be significant. The Rabbi Trusts’ assets are included in Accrued interest receivable and other assets on the accompanying Consolidated Balance Sheets. Investment earnings and any changes in fair value, as applicable, are included in Other income on the accompanying Consolidated Statements of Income. Additional information regarding the Rabbi Trusts’ investments can be found within Note 17: Fair Value Measurements.

Non-Consolidated

Low-Income Housing Tax Credit Investments. The Company makes non-marketable equity investments in entities that sponsor affordable housing and other community development projects that qualify for the LIHTC Program pursuant to Section 42 of the Internal Revenue Code. The purpose of these investments is not only to assist the Bank in meeting its responsibilities under the CRA, but also to provide a return, primarily through the realization of tax benefits. While the Company’s investment in an entity may exceed 50% of its outstanding equity interests, the entity is not consolidated as the Company is not the primary beneficiary. The Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance. The Company applies the proportional amortization method to subsequently measure its investments in qualified affordable housing projects.

The following table summarizes the Company’s LIHTC investments and related unfunded commitments:

			December 31,
(In thousands)			2025						2024
Gross investment in LIHTC investments			$	1,605,955					$	1,439,461
Accumulated amortization			(337,375)						(222,101)
Net investment in LIHTC investments			$	1,268,580					$	1,217,360
Unfunded commitments for LIHTC investments			$	634,092					$	720,890

During the years ended December 31, 2025, 2024, and 2023, the Company was approved to commit $166.5 million, $304.3 million, and $334.9 million respectively, to fund LIHTC investments.

The aggregate carrying value of the Company’s LIHTC investments and the related unfunded commitments are included in Accrued interest receivable and other assets and Accrued expenses and other liabilities, respectively, on the accompanying Consolidated Balance Sheets. The Company’s maximum exposure to loss related to its LIHTC investments is generally the aggregate carrying value as of each reporting date. However, income tax credits recognized related to these investments are subject to recapture by taxing authorities for up to a period of 15 years based on compliance provisions that are required to be met at the project level.

The following table summarizes the amount of income tax credits, other income tax benefits, and investment amortization generated from the Company’s LIHTC investments, which are recognized as a component of income tax expense on the accompanying Consolidated Statements of Income:

			Years ended December 31,
(In thousands)			2025						2024						2023
Income tax credits and other income tax benefits from LIHTC investments			$	(142,347)					$	(107,851)					$	(90,093)
Investment amortization from LIHTC investments			115,274						80,902						71,775

Income tax credits and other income tax benefits, and investment amortization generated from the Company’s LIHTC investments, are included as a component of operating activities on the accompanying Consolidated Statements of Cash Flows.

Webster Statutory Trust I. The Company owns all the outstanding common stock of Webster Statutory Trust I, a financial vehicle that has issued, and in the future may issue, trust preferred securities. The Company is not the primary beneficiary of Webster Statutory Trust I. The only assets of Webster Statutory Trust I are junior subordinated debentures that are issued by the Company, which were acquired using the proceeds from the issuance of trust preferred securities and common stock. The junior subordinated debentures are included in Long-term debt on the accompanying Consolidated Balance Sheets, and the related interest expense is included in Long-term debt on the accompanying Consolidated Statements of Income. Additional information regarding these junior subordinated debentures can be found within Note 10: Borrowings.

Multi-family Securitization Trusts. As previously discussed in Note 2: Business Developments, the Company completed a multi-family securitization in 2024. The Company has determined that it is not the primary beneficiary of the multi-family securitization trusts since it does not have the power to direct the activities that would have the most significant impact on their economic performance. The Company’s maximum exposure related to the multi-family securitization trusts is $36.4 million, which represents its obligation to Freddie Mac to guarantee losses up to 12% of the aggregate UPB of the loans at the time of sale. The obligation is secured in full by an irrevocable letter of credit issued by the FHLB.

Joint Venture with Marathon Asset Management. The Company, through its subsidiary MW Advisor Holding, LLC, owns a 50 percent interest in both MW Advisor, LLC and Marathon Direct Lending SLP, LLC. The Company (i) will receive a management fee for investment advisory and other related services performed by MW Advisor, LLC on behalf of a certain investment fund formed in connection with the joint venture (the “Fund”), and (ii) may be entitled to receive certain special limited partner carried interest distributions through its interest in Marathon Direct Lending SLP, LLC, as the designated special limited partner of the Fund. The Company has determined that it is not the primary beneficiary of either MW Advisor, LLC, Marathon Direct Lending SLP, LLC, or the Fund since it does not have the power to make decisions or control the activities that would most significantly affect their economic performance.

The carrying value of the Company’s investment in MW Advisor, LLC and Marathon Direct Lending SLP, LLC, which is included in Accrued interest receivable and other assets on the accompanying Consolidated Balance Sheets, was not significant at December 31, 2025, and 2024, and its maximum exposure to loss is equal to the carrying value plus contractual obligations to provide capital contributions in the future, which also is not significant.

Other Non-Marketable Investments. The Company invests in alternative investments comprising interests in non-public entities that cannot be redeemed since the investment is distributed as the underlying equity is liquidated. The ultimate timing and amount of these distributions cannot be predicted with reasonable certainty. For each of these alternative investments that is classified as a VIE, the Company has determined that it is not the primary beneficiary due to its inability to direct the activities that most significantly impact economic performance. The aggregate carrying value of the Company’s other non-marketable investments was $271.1 million and $216.5 million at December 31, 2025, and 2024, respectively, which is included in Accrued interest receivable and other assets on the accompanying Consolidated Balance Sheets, and its maximum exposure to loss, including unfunded commitments, was $401.2 million and $332.8 million, respectively. Additional information regarding other non-marketable investments can be found within Note 17: Fair Value Measurements.

Net income			$	1,002,802					$	768,707					$	867,840
Less: Preferred stock dividends			16,650						16,650						16,650
Income allocated to participating securities			11,291						7,981						7,922
Net income applicable to common stockholders			$	974,861					$	744,076					$	843,268
Weighted-average common shares outstanding - basic			164,842						169,820						171,775
Add: Effect of dilutive stock options and restricted stock			364						372						108
Weighted-average common shares - diluted			165,206						170,192						171,883
Earnings per common share - basic			$	5.91					$	4.38					$	4.91
Earnings per common share - diluted			5.90						4.37						4.91

Earnings per common share is calculated under the two-class method in which all earnings, distributed and undistributed, are allocated to common stock and participating securities based on their respective rights to receive dividends. The Company may provide for the grant of stock options, stock appreciation rights, restricted stock, performance-based stock, and stock units to eligible employees and directors under its stock incentive plan. Holders of restricted stock are entitled to receive non-forfeitable dividends during the vesting period on a basis equivalent to the dividends paid to holders of common stock. These unvested awards meet the definition of participating securities.

Potential common shares from performance-based restricted stock that were not included in the computation of diluted earnings per common share because they were anti-dilutive under the treasury stock method were zero, zero, and 204,945 for the years ended December 31, 2025, 2024, and 2023, respectively. Additional information regarding the issuance of stock awards under the Company’s stock incentive plan can be found within Note 19: Stock-Based Compensation Plans.

Note 16: Derivative Financial Instruments

Derivative Positions and Offsetting

Derivatives Designated in Hedge Relationships. Interest rate swaps allow the Company to change the fixed or variable nature of an interest rate without the exchange of the underlying notional amount. Certain pay fixed/receive variable interest rate swaps are designated as cash flow hedges to effectively convert variable-rate debt into fixed-rate debt, whereas certain receive fixed/pay variable interest rate swaps are designated as fair value hedges to effectively convert fixed-rate debt into variable-rate debt. Certain purchased options are also designated as cash flow hedges, allowing the Company to limit the potential adverse impact of variable interest rates by establishing a cap rate or floor rate in exchange for an upfront premium. The purchased options designated as cash flow hedges represent interest rate caps where payment is received from the counterparty if interest rates rise above the cap rate, and interest rate floors where payment is received from the counterparty when interest rates fall below the floor rate. The maximum length of time over which forecasted transactions are hedged is 2.1 years.

Derivatives Not Designated in Hedge Relationships. The Company also enters into derivative transactions that are not designated in hedge relationships. The Company has a back-to-back swap program, whereby it enters into an interest rate swap with a qualified customer and simultaneously enters into an equal and opposite interest-rate swap with a swap counterparty, to hedge interest rate risk. Derivative assets and derivative liabilities with the same counterparty are presented on a net basis when master netting agreements are in place.

The following tables present the notional amounts and fair values, including accrued interest, of derivative positions:

(1)The notional amounts of interest rate swaps that were centrally-cleared through clearing housings was $65.3 million at December 31, 2025, and $71.1 million at December 31, 2024, for asset derivatives, and $126.5 million at December 31, 2025, and zero at December 31, 2024, for liability derivatives. Interest rate swaps that are centrally-cleared through clearing houses are “settled-to-market” and considered a single unit of account. In accordance with their rule books, clearing houses record the variation margin transferred for settled-to-market derivatives as a legal settlement of the derivative contract (i.e., the variation margin legally settles the outstanding exposure, but does not result in any other change or reset of the contractual terms of the derivative). The fair values of the Company’s settled-to-market interest rate swaps are presented net on the accompanying Consolidated Balance Sheets and approximated zero.

(2)Other derivatives not designated in hedge relationships included foreign currency forward contracts related to lending arrangements, a Visa equity swap transaction, and risk participation agreements. The notional amount of risk participation agreements was $370.1 million at December 31, 2025, and $294.5 million at December 31, 2024, for asset derivatives, and $965.4 million at December 31, 2025, and $796.6 million at December 31, 2024, for liability derivatives, all of which had immaterial related fair values.

Derivative Exposure. At December 31, 2025, the Company had $84.5 million of cash collateral received and $13.8 million of cash collateral posted included in Cash and due from banks on the accompanying Consolidated Balance Sheets. In addition, the Company had $3.5 million in initial margin posted at clearing houses. The Company regularly evaluates the credit risk of its derivative customers, taking into account the likelihood of default, net exposures, and remaining contractual life, among other related factors. Credit risk exposure is mitigated as transactions with customers are generally secured by the same collateral of the underlying transactions. Current net credit exposure relating to derivatives with the Bank’s customers was $76.3 million at December 31, 2025. In addition, the Company monitors potential future exposure, representing its best estimate of exposure to remaining contractual maturity. The potential future exposure relating to derivatives with the Bank’s customers totaled $126.9 million at December 31, 2025. The Company has incorporated a credit valuation adjustment to reflect non-performance risk in the fair value measurement of its derivatives, which totaled $4.2 million at December 31, 2025, and $7.6 million at December 31, 2024. Various factors impact changes in the credit valuation adjustment over time, such as changes in the credit spreads of the contracted parties, and changes in market rates and volatilities, which affect the total expected exposure of the derivative instruments.

Note 17: Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The determination of fair value may require the use of estimates when quoted market prices are not available. Fair value estimates made at a specific point in time are based on management’s judgments regarding future expected losses, current economic conditions, the risk characteristics of each financial instrument, and other subjective factors that cannot be determined with precision.

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The three levels within the fair value hierarchy are as follows:

•Level 1: Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Company has the ability to access at the measurement date.

•Level 2: Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability (i.e., interest rates, rate volatility, prepayment speeds, and credit ratings), or inputs that are derived principally from or corroborated by market data, correlation or other means.

•Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. This includes certain pricing models or other similar techniques that require significant management judgment or estimation.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Available-for-Sale Securities. When unadjusted quoted prices are available in an active market, the Company classifies its available-for-sale securities within Level 1 of the fair value hierarchy. When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service’s results and has a process in place to challenge their valuations and methodologies. Government agency debentures, Municipal bonds and notes, Agency CMO, Agency MBS, Agency CMBS, CMBS, Corporate debt, Private label MBS, and Other available-for-sale securities are classified within Level 2 of the fair value hierarchy.

Derivative Financial Instruments. The fair values presented for derivative financial instruments include any accrued interest. Foreign exchange contracts are valued based on unadjusted quoted prices in active markets and, accordingly, are classified within Level 1 of the fair value hierarchy. Except for mortgage banking derivatives, all other derivative financial instruments are valued using third-party valuation software, which considers the present value of cash flows discounted using observable forward rate assumptions. The resulting fair value is then validated against valuations performed by dealer counterparties. Credit valuation adjustments, which are included in the fair value of derivative financial instruments, utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by its counterparties. When credit valuation adjustments are significant to the overall fair value of a derivative financial instrument, the Company classifies that derivative financial instrument in Level 3 of the fair value hierarchy. Otherwise, derivative financial instruments are generally classified within Level 2 of the fair value hierarchy. At December 31, 2025, and 2024, these credit valuation adjustments were not considered significant to the overall fair value of the Company’s derivative financial instruments.

Mortgage Banking Derivatives. The Company uses forward sales of mortgage loans and mortgage-backed securities to manage the risk of loss associated with its mortgage loan commitments and mortgage loans held for sale. Prior to closing and funding certain single-family residential mortgage loans, an interest rate lock commitment is generally extended to the borrower. During this in-between time period, the Company is subject to the risk that market interest rates may change. If rates rise, investors generally will pay less to purchase mortgage loans, which would result in a reduction in the gain on sale of the loans, or possibly a loss. In an effort to mitigate this risk, forward delivery sales commitments are established in which the Company agrees to either deliver whole mortgage loans to various investors or issue mortgage-backed securities. The fair value of mortgage banking derivatives is determined based on current market prices for similar assets in the secondary market. Accordingly, mortgage banking derivatives are classified within Level 2 of the fair value hierarchy.

Loans Originated For Sale. The Company has elected to measure residential mortgage loans originated for sale at fair value under the fair value option per ASC Topic 825, Financial Instruments. Electing to measure residential mortgage loans originated for sale at fair value reduces certain timing differences and better reflects the price the Company would expect to receive from the sale of these loans. The fair value of residential mortgage loans originated for sale is based on quoted market prices of similar loans sold in conjunction with securitization transactions. Accordingly, residential mortgage loans originated for sale are classified within Level 2 of the fair value hierarchy.

133

Table of Contents

The following table compares the fair value to the UPB of residential mortgage loans held for sale:

			December 31,
			2025																		2024
(In thousands)			Fair Value						UPB						Difference						Fair Value						UPB						Difference
Originated loans held for sale			$	2,142					$	2,068					$	74					$	297					$	283					$	14

Rabbi Trust Investments. Investments held in each of the Company’s Rabbi Trusts reported at fair value consist primarily of mutual funds that invest in equity and fixed income securities. Shares of these mutual funds are valued based on the NAV as reported by the trustee of the funds, which represents quoted prices in active markets. Accordingly, these Rabbi Trusts’ investments are classified within Level 1 of the fair value hierarchy. At December 31, 2025, and 2024, the total cost basis of the investments held in these Rabbi Trusts was $11.2 million and $9.2 million, respectively.

Alternative Investments. Equity investments have a readily determinable fair value when unadjusted quoted prices are available in an active market for identical assets. Accordingly, these alternative investments are classified within Level 1 of the fair value hierarchy. In 2024, the Company sold its equity investments with a readily determinable fair value for proceeds of $1.2 million. Prior to the sale, these alternative investments experienced total write-ups in fair value of $0.3 million. There were no equity investments with a readily determinable fair value at December 31, 2025, and 2024.

Equity investments that do not have a readily determinable fair value may qualify for the NAV practical expedient if they meet certain requirements. The Company’s alternative investments measured at NAV consist of investments in non-public entities that cannot be redeemed since investments are distributed as the underlying equity is liquidated. Alternative investments measured at NAV are not classified within the fair value hierarchy. At December 31, 2025, and 2024, these alternative investments had a total carrying amount of $57.5 million and $43.4 million, respectively, and a remaining unfunded commitment of $52.2 million and $30.1 million, respectively.

Contingent Consideration. The Company recorded contingent consideration at fair value related to one earn‑out agreement associated with the SecureSave acquisition completed in December 2025. The earn‑out is based on total program deposits measured as of three future measurement dates, with a payment due only if total program deposits exceed the program deposit threshold and, if so, (i) equal to total program deposits multiplied by the applicable earn-out rate for the measurement dates on December 31, 2026, and December 31, 2027, and (ii) equal to the total program deposits in excess of the program deposit threshold multiplied by the earn-out rate for the measurement date on December 31, 2028. The contingent consideration is payable in cash up to an aggregate maximum of $35.0 million.

The following table summarizes the significant inputs used to derive the estimated fair value of the Company’s contingent consideration liability associated with the SecureSave acquisition at December 31, 2025 (dollars in thousands):

			Contractual Inputs												Unobservable Inputs
Measurement date			Program Deposit Threshold			Earn-Out Rate			Aggregate Maximum Earn-Out						Projected Program Deposits			Earn-Out Metric Discount Rate			Deposit Volatility			Payout Present Value Factor						Fair Value
December 31, 2026			$	145,000		1.0		%	$	35,000					$	146,700		15.1		%	14.0		%	0.94						$	417
December 31, 2027			402,500			1.5			35,000						485,405			15.0			14.0			0.90						2,998
December 31, 2028			681,000			5.0			35,000						1,034,752			15.0			14.0			0.86						5,005

The estimated fair values of the SecureSave contingent consideration liabilities are measured on a recurring basis and determined using a Monte Carlo simulation which utilizes contractual inputs and management’s evaluation of unobservable inputs such as projected program deposits, an earn-out metric discount rate, deposit volatility, and the payout present value factor. The unobservable inputs, which are the responsibility of management and were calculated with the assistance of a third-party valuation specialist, are not observable, and accordingly, are classified within Level 3 of the fair value hierarchy.

The Company also recorded contingent consideration at fair value related to two earn-out agreements associated with the acquisition of interLINK Insured Sweep LLC from StoneCastle Partners LLC in January 2023. The terms of the purchase agreement specified that the seller would receive earn-outs based on the ability of the Company to: (i) re-sign the existing broker dealers under contract, and (ii) generate $2.5 billion in new broker dealer deposit programs within three years of the acquisition date. As of the third quarter of 2025, the Company had settled all of its contingent consideration obligations with StoneCastle Partners LLC in accordance with the purchase agreement.

Table of Contents

The following table summarizes the significant inputs used to derive the estimated fair value of the Company’s contingent consideration liability associated with the interLINK acquisition at December 31, 2024 (dollars in thousands):

Agreement			Maximum Amount			Probability of Achievement			Payment Term (in years)			Discount Rate			Fair Value
(i) Re-sign broker dealers (1)			$	207		99.0 %			0.88			6.40 %			$	182
(ii) Deposit program growth (2)			$	12,500		100.0 %			0.50			6.40 %			$	11,568

(1)The Company re-signed the last existing broker dealer under contract in July 2025, which resulted in the cash payment of $0.2 million and an immaterial fair value adjustment.

(2)During the first quarter of 2025, the Company re-evaluated its estimate of the forecasted achievement date (payment term) for the deposit program growth event earn-out, which resulted in a revised expected achievement date of April 30, 2025, instead of June 30, 2025. This change in estimate resulted in an increase in fair value of $0.9 million. The Company generated the required $2.5 billion in new broker dealer deposit programs in April 2025, which resulted in the cash payment of $12.5 million.

The estimated fair values of the interLINK contingent consideration liabilities are measured on a recurring basis and determined using an income approach considering management’s evaluation of the probability of achievement, forecasted achievement date (payment term), and a discount rate equivalent to the cost of debt. These significant inputs, which are the responsibility of management and were calculated with the assistance of a third-party valuation specialist, are not observable, and accordingly, are classified within Level 3 of the fair value hierarchy.

Contingent consideration liabilities are included in Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets. Any fair value adjustments to contingent consideration liabilities are included in Other expense on the accompanying Consolidated Statements of Income.

(1)Additional information regarding the impact of netting derivative assets and derivative liabilities, as well as the impact from offsetting cash collateral with the same derivative counterparties, can be found within Note 16: Derivative Financial Instruments.

(2)Certain alternative investments are recorded at NAV. Assets measured at NAV are not classified within the fair value hierarchy.

Assets Measured at Fair Value on a Non-Recurring Basis

The Company measures certain assets at fair value on a non-recurring basis. The following is a description of valuation methodologies used for assets measured at fair value on a non-recurring basis.

Alternative Investments. The measurement alternative has been elected for alternative investments without readily determinable fair values that do not qualify for the NAV practical expedient. The measurement alternative requires investments to be measured at cost minus impairment, if any, plus or minus adjustments resulting from observable price changes in orderly transactions for an identical or similar investment of the same issuer. Accordingly, these alternative investments are classified within Level 2 of the fair value hierarchy. At December 31, 2025, and 2024, the carrying amount of these alternative investments was $86.1 million and $61.5 million, respectively, of which $7.5 million and $8.3 million, respectively, were considered to be measured at fair value. During the year ended December 31, 2025, there were $2.0 million in total write-ups due to observable price changes and $0.5 million of total write-downs due to impairment. Additionally, during the year ended December 31, 2025, the Company sold alternative investments with a carrying amount of $4.6 million, for which the measurement alternative was elected, for proceeds of $13.4 million, resulting in total gains on sale of $8.8 million.

Loans Transferred to Held for Sale. Once a decision has been made to sell loans that were not previously classified as held for sale, these loans are transferred into the held for sale category and carried at the lower of cost or fair value, less estimated costs to sell. At the time of transfer and classification as held for sale, any amount by which cost exceeds fair value is accounted for as a valuation allowance. This activity generally pertains to loans with observable inputs and, therefore, are classified within Level 2 of the fair value hierarchy. However, should these loans include adjustments for changes in loan characteristics based on unobservable inputs, the loans would then be classified within Level 3 of the fair value hierarchy. At December 31, 2025, and 2024, there were $12.7 million and $27.3 million, respectively, of loans on the accompanying Consolidated Balance Sheets that had been transferred to held for sale.

Collateral Dependent Loans and Leases. Loans and leases for which repayment is substantially expected to be provided through the operation or sale of collateral are considered collateral dependent, and are valued based on the estimated fair value of the collateral, less estimated costs to sell at the reporting date, using customized discounting criteria. Accordingly, collateral dependent loans and leases are classified within Level 3 of the fair value hierarchy.

Table of Contents

Other Real Estate Owned and Repossessed Assets. OREO and repossessed assets are held at the lower of cost or fair value and are considered to be measured at fair value when recorded below cost. The fair value of OREO is calculated using independent appraisals or internal valuation methods, less estimated selling costs, and may consider available pricing guides, auction results, and price opinions. Certain repossessed assets may also require assumptions about factors that are not observable in an active market when determining fair value. Accordingly, OREO and repossessed assets are classified within Level 3 of the fair value hierarchy. At December 31, 2025, and 2024, the total carrying value of OREO and repossessed assets was $1.5 million and $0.4 million, respectively. In addition, the amortized cost of consumer loans secured by residential real estate property that were in the process of foreclosure at December 31, 2025, was $9.0 million.

Estimated Fair Values of Financial Instruments

The Company is required to disclose the estimated fair values of certain financial instruments. The following is a description of the valuation methodologies used to estimate fair value for those assets and liabilities.

Cash and Cash Equivalents. Given the short time frame to maturity, the carrying amount of cash and cash equivalents, which is comprised of Cash and due from banks and Interest-bearing deposits, approximates fair value. Cash and cash equivalents are classified within Level 1 of the fair value hierarchy.

Held-to-Maturity Securities. When quoted market prices are not available, the Company employs an independent pricing service that utilizes matrix pricing to calculate fair value. These fair value measurements consider observable data, such as dealer quotes, market spreads, cash flows, yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the respective terms and conditions for debt instruments. Management maintains procedures to monitor the pricing service’s results and has a process in place to challenge their valuations and methodologies. Held-to-maturity securities, which include Agency CMO, Agency MBS, Agency CMBS, Municipal bonds and notes, and CMBS, are classified within Level 2 of the fair value hierarchy.

Loans and Leases, net. Except for collateral dependent loans and leases, the fair value of loans and leases held for investment is estimated using a discounted cash flow methodology, based on future prepayments and market interest rates inclusive of an illiquidity discount for comparable loans and leases. The associated cash flows are then adjusted for associated credit risks and other potential losses, as appropriate. Loans and leases, net are classified within Level 3 of the fair value hierarchy.

Deposit Liabilities. The fair value of deposit liabilities, which is comprised of non-interest-bearing demand deposits, interest-bearing checking, health savings, money market, and savings accounts, reflects the amount payable on demand at the reporting date. Deposit liabilities are classified within Level 2 of the fair value hierarchy.

Time Deposits. The fair value of fixed-maturity certificates of deposit is estimated by discounting contractual cash flows using current market rates for financial instruments with similar maturities. Time deposits are classified within Level 2 of the fair value hierarchy.

Securities Sold Under Agreements to Repurchase and Federal Funds Purchased. The fair value of securities sold under agreements to repurchase and federal funds purchased that mature within 90 days approximates their carrying value. The fair value of securities sold under agreements to repurchase and federal funds purchased that mature after 90 days is estimated using a discounted cash flow methodology based on current market rates and adjusted for associated credit risks, as appropriate. Securities sold under agreements to repurchase and federal funds purchased are each classified within Level 2 of the fair value hierarchy.

Federal Home Loan Bank Advances and Long-Term Debt. The fair value of FHLB advances and long-term debt is estimated using a discounted cash flow methodology in which discount rates are matched with the time period of the expected cash flows and adjusted for associated credit risks, as appropriate. FHLB advances and long-term debt are each classified within Level 2 of the fair value hierarchy.

Note 18: Retirement Benefit Plans

Defined Benefit Pension and Other Postretirement Benefit Plans

The Bank had offered a qualified noncontributory defined benefit Pension Plan (“Webster Bank Pension Plan”) and a non-qualified SERP (“Webster Bank Supplemental Defined Benefit Plan for Executive Officers”) to eligible employees and key executives who met certain age and service requirements, both of which were frozen effective December 31, 2007. Only those employees who were hired prior to January 1, 2007, and who became participants of the plans prior to January 1, 2008, have accrued benefits under the plans. The Bank also provides an OPEB plan to certain retired employees (“Webster Bank Postretirement Medical Benefit Plan”).

In connection with the Sterling merger in 2022, the Company assumed the benefit obligations of Sterling’s non-qualified SERPs, which included the Astoria Bank Excess Benefit and Supplemental Benefit Plans, Astoria Bank Directors’ Retirement Plan, Retirement Plan of the Greater New York Saving Bank for Non-Employee Directors, Supplemental Executive Retirement Plan of Provident Bank, and the Supplemental Executive Retirement Plan of Provident Bank - Other; and OPEB plans, which included the Sterling Bancorp Supplemental Postretirement Life Insurance Plan, Astoria Postretirement Welfare Benefit Plans, and a Split Dollar Life Insurance Arrangement. In 2024, the Split Dollar Life Insurance Arrangement was liquidated.

In 2025, the Eagle Benefit Equalization Plan, which is a non-qualified SERP that had previously been managed off-balance sheet, was integrated into the Company’s consolidated financial statements.

Each of the above plan’s measurement dates coincides with the Company’s December 31 year end.

The following table summarizes the changes in the benefit obligation, fair value of plan assets, and funded status of the defined benefit pension and other postretirement benefit plans at December 31:

			Pension									SERP									OPEB

(1)Reflects the benefit obligation as of the date that the Eagle Benefit Equalization Plan was integrated into the Company’s consolidated financial statements in 2025.

(2)The change in actuarial (gain) loss is primarily due to actuarial losses in 2025 resulting from a decrease in discount rates, as compared to actuarial (gains) in 2024 resulting from an increase in discount rates.

(3)The increase in the actual return on plan assets for the Pension Plan is primarily due to the performance of fixed income investments, which comprise approximately 65% of the portfolio. In 2025, fixed income investments earned a positive return, as compared to a negative return in 2024.

(4)The overfunded (underfunded) status of each plan is respectively included in Accrued interest receivable and other assets or Accrued expenses and other liabilities on the accompanying Consolidated Balance Sheets, as applicable.

Asset Management

The Pension Plan invests primarily in common collective trusts and registered investment companies. However, the Pension Plan’s investment policy guidelines also allow for the investment in cash and cash equivalents, fixed income securities, and equity securities. Common collective trusts and registered investment companies are both benchmarked against the Standard & Poor’s 500 Index. Incremental benchmarks used to assess the common collective trusts include the S&P 400 Mid Cap Index, Russell 200 Index, MSCI ACWI ex U.S. Index, and the Bloomberg U.S. Long Credit Index. The standard deviation should not exceed that of the composite index. The Pension Plan’s investment strategy and asset allocations are monitored by the Company’s Retirement Plans Committee with the assistance of external investment advisors, and the investment portfolio is rebalanced, as appropriate. The target asset allocation percentages for the year ended December 31, 2025, were 64.5%
fixed-income investments and 35.5% equity investments. The actual asset allocation percentages for the year ended
December 31, 2025, were 64.1% fixed-income investments, 35.3% equity investments, and 0.6% cash and cash equivalents.

The overall investment objective of the Pension Plan is to maintain a diversified portfolio with a targeted expected long-term rate of return on plan assets of approximately 6.00%. The expected long-term rate of return on plan assets is the average rate of return expected to be realized on funds invested, or expected to be invested, to provide for the benefits included in the benefit obligation. The expected long-term rate of return on plan assets is generally established as of the beginning of the year based upon historical and projected returns for each asset category, with subsequent remeasurements occurring in interim periods, as appropriate. Depending on market conditions, the expected long-term rate of return on plan assets may exceed or fall short of the targeted percentage.

Fair Value Measurement

The following is a description of the valuation methodologies used for the Pension Plan’s assets measured at fair value:

Common Collective Trusts. Common collective trusts are valued based on the net asset value as reported by the trustee of the funds. The underlying investments of the common collective trusts are valued using quoted market prices in active markets or observable inputs for similar assets. Therefore, common collective trusts are classified as Level 2 within the fair value hierarchy.

Registered Investment Companies. Registered investment companies are valued at the daily closing price as reported by the fund. Registered investment companies held by the Plan are quoted in an active market and are classified as Level 1 within the fair value hierarchy.

The following table sets forth by level within the fair value hierarchy the Pension Plan’s assets at fair value:

			December 31,

Multiple-Employer Defined Benefit Pension Plan

The Bank participates in a multi-employer plan that provides pension benefits to former employees of a bank acquired by the Company. Participation in the plan was frozen as of September 1, 2004. The plan maintains a single trust and does not segregate the assets or liabilities of its participating employers. Minimum required employer contributions are determined by an independent actuary and are calculated using a 15-year shortfall amortization factor. There are no collective bargaining agreements or other obligations requiring contributions to the plan, nor has a funding improvement plan been implemented.

The following table summarizes information related to the Bank’s participation in the multi-employer plan:

(Dollars in thousands)																								Contributions Years Ended December 31,												Funded Status At December 31,
Plan Name						Employer Identification Number						Plan Number						Surcharge Imposed						2025			2024			2023						2025			2024
Pentegra Defined Benefit Plan for Financial Institutions						13-5645888						333						No						$475			$482			$448						At least 80 percent			At least 80 percent

The Bank’s contributions to the multi-employer plan for the years ended December 31, 2025, 2024, and 2023, did not exceed more than 5% of total plan contributions for the plan years ended June 30, 2024, 2023, and 2022. The plan’s Form 5500 was not available for the plan year ended June 30, 2025, as of the date the Company’s Consolidated Financial Statements were issued. As of July 1, 2025, the date of the most recent actuarial valuation, the plan administrator confirmed that the Bank’s portion of the multi-employer plan was $2.8 million underfunded.

Defined Contribution Postretirement Benefit Plans

The Bank also sponsors the Webster Bank Retirement Savings Plan, which is a defined contribution postretirement benefit plan established under Section 401(k) of the Internal Revenue Code. Under the Webster Bank Retirement Savings Plan, employees who have met a certain age requirement may elect to contribute a percentage of their eligible compensation to the plan on either a pre-tax or post-tax basis. During the years ended December 31, 2025, 2024, and 2023, the Bank made matching employer contributions to their accounts equal to 100% of the first 2% and 50% of the next 6% of participants’ contributions.

The Sterling National Bank 401k and Profit Sharing Plan, which was offered to eligible legacy Sterling employees who became employees of the Company in 2022, was effectively merged with and into the Webster Bank Retirement Savings Plan on December 29, 2023. Prior to the merger of these plans, participants of the Sterling National Bank 401(k) and Profit Sharing Plan could elect to contribute a percentage of their eligible compensation to the plan on either a pre-tax or post-tax basis. During the year ended December 31, 2023, the Bank made (i) matching employer contributions equal to 50% of participant contributions up to 4% of eligible compensation for a maximum match of 2%, and (ii) profit sharing contributions equal to 3% of eligible compensation for all eligible legacy Sterling participants, regardless of whether they had contributed to the plan.

Compensation and benefits expense included total employer contributions under the defined contribution postretirement benefit plans of $23.4 million, $20.6 million, and $20.3 million for the years ended December 31, 2025, 2024, and 2023, respectively.

Note 19: Stock-Based Compensation Plans

The Company maintains a stock compensation plan that provides for the grant of stock options, stock appreciation rights, restricted stock, performance-based stock, and stock units to better align the interests of its employees and directors with those of its stockholders. The total number of shares of Webster common stock authorized for issuance under the plan is 21.4 million shares. At December 31, 2025, there were 2.2 million shares available to be granted. Stock compensation expense is recognized over the required service vesting period for each award based on the grant-date fair value and is included in Compensation and benefits on the accompanying Consolidated Statements of Income.

The following table summarizes stock-based compensation plan activity for the year ended December 31, 2025:

			Non-Vested Restricted Stock Awards Outstanding																		Stock Options Outstanding
			Time-Based																								Performance-Based
			Number of Shares			Weighted-Average Grant Date Fair Value															Number of Shares			Weighted-Average Grant Date Fair Value						Number of Shares			Weighted-Average Exercise Price

Balance, end of period			1,909,582			51.48															501,725			52.44						—			—

Restricted Stock Awards

Time-based restricted stock awards vest over the applicable service period primarily ranging from one to three years. Under the plan, the number of time-based restricted stock awards that may be granted to an eligible individual per calendar year is limited to 300,000 shares. The fair value of time-based restricted stock awards used to determine compensation expense is measured using the closing price of Webster common stock at the grant date.

Performance-based restricted stock awards generally vest after a three year performance period, with the total share quantity dependent on the Company meeting certain target performance conditions ranging from 0% to 150%. Under the plan, 50% of the share quantity is determined based on three-year total stockholder return as compared to the Company’s compensation peer group, while the other 50% is based on the Company’s average return on equity over the three-year period. The fair value of performance-based restricted stock awards used to determine compensation expense is calculated using the Monte-Carlo simulation model for total stockholder return awards and the closing price of Webster common stock at the grant date for average return on equity awards. Compensation expense for average return on equity awards is subject to adjustment based on the Company’s average return on equity performance relative to the target number of shares condition.

The Company recognized restricted stock compensation expense of $56.8 million, $55.1 million, and $54.5 million, during the years ended December 31, 2025, 2024, and 2023, respectively, in which the related income tax benefit was $16.3 million, $12.8 million, and $13.9 million, respectively. The fair value of restricted stock awards that had vested during the years ended December 31, 2025, 2024, and 2023, was $54.2 million, $49.7 million, and $39.9 million, respectively. At December 31, 2025, there was $42.7 million of unrecognized restricted stock expense related to non-vested restricted stock awards, which is expected to be recognized over a weighted-average period of 1.8 years.

Stock Options

Stock options, incentive and non-incentive, are granted at an exercise price equal to the market value of Webster common stock on the grant date. Each option grants the holder the right to acquire one share of Webster common stock over a contractual life of ten years. While the Company has not granted stock options since 2013, replacement options were issued in 2022 in order for the Company to satisfy its consideration under the Sterling merger agreement. During the year ended December 31, 2025, the remainder of the replacement options issued in connection with the Sterling merger were exercised. As a result, there were no incentive stock options outstanding at December 31, 2025.

For the years ended December 31, 2025, 2024, and 2023, the total intrinsic value of the options exercised was $0.1 million, $0.3 million, and $2.2 million, respectively. The amount of cash received from the exercise of stock options during the years ended December 31, 2025, 2024, and 2023, was $0.1 million, $0.3 million, and $1.8 million, respectively.

Note 20: Segment Reporting

The Company’s operations are organized into three reportable segments that represent its differentiated lines of business: Commercial Banking, Healthcare Financial Services, and Consumer Banking. The Company’s CODM is the Chairman and Chief Executive Officer. The CODM uses income before income taxes and the provision for credit losses, referred to as PPNR, to allocate resources, including financial and capital resources, employees, and property, for each segment predominantly in the annual budget and forecasting process. The CODM considers budget-to-actual variances on a monthly basis when making decisions about allocating resources to the segments. The CODM also uses PPNR to assess the performance of each segment and in the compensation of certain employees.

Commercial Banking delivers financial solutions nationally to a wide range of companies, investors, government entities, and other public and private institutions. Commercial Banking helps its clients achieve their business and financial goals with expertise in Commercial Real Estate, Middle Market, Sponsor and Specialty Finance, Verticals and Regional Banking, Asset Based Lending and Commercial Services, and Treasury Management. Commercial Banking’s Private Banking team also pairs holistic wealth solutions, including tailored lending, with commercial banking services.

Healthcare Financial Services includes HSA Bank and Ametros. HSA Bank is one the country’s largest providers of employee benefits solutions, including being one of the leading bank administrators of HSAs, emergency savings accounts, and flexible spending account administration services in 50 states. Ametros, the nation’s largest professional administrator of medical insurance claim settlements, helps individuals manage their ongoing medical care through their CareGuard service and proprietary technology platform.

Consumer Banking delivers customized financial solutions to individuals, families, and small to mid-sized businesses through it experienced relationship managers and wealth advisors across 195 banking centers located throughout the Northeast. Consumer Banking offers a full suite of deposit, lending, treasury management, and wealth management solutions. Consumer Banking also provides a fully digital banking experience through its mobile banking apps and BrioDirect.

Corporate and Reconciling Category

Certain Treasury activities and other corporate and functional divisions, such as information technology, human resources, risk management, bank operations, and the operations of interSYNC, and amounts required to reconcile non-GAAP profitability metrics to those reported in accordance with GAAP are included in the Corporate and Reconciling category.

In addition to the amounts required to reconcile non-GAAP profitability metrics (i.e., estimates for FTP, allocations of equity capital) to those reported in accordance with GAAP, revenues reported in the Corporate and Reconciling category also include gains/losses from sales of investments securities, extinguishments of long-term debt, certain swaps, and bank-owned life insurance, and immaterial revenues from contracts with customers attributable to interSYNC. Neither the Treasury function nor interSYNC operations meet the definition of an operating segment, and therefore, are not considered for determining reportable segments.

Total assets reported in the Corporate and Reconciling category consists primarily of cash and cash equivalents, investment securities, FHLB/FRB stock, and other assets. The ACL on loans and leases is also reported in Total assets in the Corporate and Reconciling category. A provision for credit losses is allocated from the Corporate and Reconciling category to Commercial Banking and Consumer Banking based on the expected loss content of their specific loan and lease portfolios over a 3-year period (non-GAAP). There is no provision for credit losses associated with Healthcare Financial Services since that segment does not originate nor acquire loans and leases. Business development expenses, which include merger-related expenses and other strategic initiatives and restructuring costs, are also generally included in the Corporate and Reconciling category.

Change in Reportable Segments

From time to time, the Company may make reclassifications among the reportable segments to more appropriately reflect management’s view of the business and/or based on changes in the Company’s organizational structure or product lines. Accordingly, the results derived are not necessarily comparable with similar financial information published by other financial institutions. Additionally, because of the interrelationships of the segments, the financial information presented is not indicative of how the segments would perform if they operated as independent entities.

Effective January 1, 2024, the Company realigned certain of its Business Banking operations to better serve its customers and deliver operational efficiencies. Under this realignment, $1.5 billion of loans and $2.2 billion of deposits were reassigned, and $77.2 million of goodwill was reallocated on a relative fair value basis, from Commercial Banking to Consumer Banking. There was no goodwill impairment as a result of this realignment. Amounts for the year ended December 31, 2023, have been recast accordingly.

With the acquisition of Ametros on January 24, 2024, the Company formed the Healthcare Financial Services reportable segment, which includes the aggregated financial information of the HSA Bank and Ametros operating segments. The financial information presented within Healthcare Financial Services for the year ended December 31, 2023, reflects that only of the HSA Bank operating segment.

Segment Reporting Methodology

The Company uses an internal profitability reporting system to generate PPNR by reportable segment, which is comprised of direct revenues, direct expenses, estimates for FTP, and allocations for equity capital, net operating costs, and total support costs. Since the majority of each reportable segment’s revenue is interest, each segment’s interest revenue is reported net of its interest expense (“net interest income”). Estimates for FTP and allocations of equity capital and non-interest expense, certain of which are subjective in nature, are periodically reviewed and refined. Equity capital is allocated using a combination of risk-weighted asset and management assessment methodologies across the differentiated lines of business. Net operating costs and total support costs, which reflect costs for shared services and back-office support areas, are allocated using an activity and driver-based costing process. The full profitability measurement reports, which are prepared for each reportable segment and reviewed by the CODM on a monthly basis, reflect non-GAAP reporting methodologies. The differences between full profitability and GAAP results are reconciled in the Corporate and Reconciling category.

The goal of FTP is to encourage loan and deposit growth consistent with the Company’s overall profitability objectives. The FTP process considers the specific interest rate risk and liquidity risk of financial instruments, other assets, and other liabilities included in each reportable segment. Loans and deposits are assigned FTP rates, and segments are charged a cost to fund loans and are paid a credit for deposit funds provided. Consideration is given to the origination date and the earlier of the maturity date or the repricing date of a financial instrument to assign an FTP rate for loans and deposits originated each day. Overall, the FTP process reflects the transfer of interest rate risk exposure to the Treasury function included within the Corporate and Reconciling category, where such exposures are centrally managed.

Major Revenue Streams

Deposit Service Fees. Deposit service fees consists of fees earned from commercial and consumer customer deposit accounts, such as account maintenance and cash management/analysis fees, as well as other transactional service charges (i.e., insufficient funds, wire transfers, stop payment fees, etc.). Performance obligations for account maintenance services and cash management/analysis fees are satisfied on a monthly basis at a fixed transaction price, whereas performance obligations for other deposit service charges that result from various customer-initiated transactions are satisfied at a point-in-time when the service is rendered. Payment for deposit service fees is generally received immediately or in the following month through a direct charge to the customers’ accounts. Certain commercial customer contracts include credit clauses, whereby the Company will grant credit upon the customer meeting pre-determined conditions, which can be used to offset fees. In addition, certain healthcare financial services contracts include revenue share clauses, whereby the Company will reduce or refund deposit service fees or make referral payments to attract and retain customers and their accounts. Such revenue share costs are recognized as a reduction to revenue in the period incurred. On occasion, the Company may also waive certain fees. Fee waivers are recognized as a reduction to revenue in the period the waiver is granted to the customer.

The deposit service fees revenue stream also includes interchange fees earned from debit and credit card transactions. The transaction price for interchange services is based on the transaction value and the interchange rate set by the card network. Performance obligations for interchange fees are satisfied at a point-in-time when the cardholders’ transaction is authorized and settled. Payment for interchange fees is generally received immediately or in the following month.

Loan and Lease Related Fees. As previously discussed in Note 2: Business Developments, the Company sold its factored receivables loan portfolio, which included the related customer contracts, in the third quarter of 2024. Prior to the completion of that transaction, the Company recognized factored receivables non-interest income from fees earned from accounts receivable management services. The Company factored accounts receivable, with and without recourse, for customers whereby the Company purchased their accounts receivable at a discount and assumed the risk, as applicable, and ownership of the assets through direct cash receipt from the end consumer. Factoring services were performed in exchange for a non-refundable fee at a transaction price based on a percentage of the gross invoice amount of each receivable purchased, subject to a minimum required amount. The performance obligation for factoring services was generally satisfied at a point-in-time when the receivable was assigned to the Company. However, if the commission earned did not meet or exceed the minimum required annual amount, the difference between that and the actual amount was recognized at the end of the contract term. Other fees associated with factoring receivables included wire transfer and technology fees, field examination fees, and Uniform Commercial Code fees, where the performance obligations were satisfied at a point-in-time when the services were rendered. Payment from the customer for factoring services was generally received immediately or within the following month.

Payroll finance non-interest income consists of fees earned from performing payroll financing and business process outsourcing services, including full back-office technology and tax accounting services, along with payroll preparation, making payroll tax payments, invoice billings, and collections for independently-owned temporary staffing companies nationwide. Performance obligations for payroll finance and business processing activities are either satisfied upon completion of the support services or as payroll remittances are made on behalf of customers to fund their employee payroll, which generally occurs on a weekly basis. The agreed-upon transaction price is based on a fixed-percentage per the terms of the contract. The Company also withholds an agreed-upon hold-back reserve, which may be applied to cover defaults or other amounts owed to the Company under the contract, and which is returnable to the customer upon termination of the contract provided that all contractual obligations have been fully satisfied. When the Company collects on amounts due from end consumers on behalf of its customers and at the time of financing payroll, the Company retains the agreed-upon transaction price payable for the performance of its services and remits an amount to the customer net of any advances and payroll tax withholdings, as applicable.

Wealth and Investment Services. Wealth and investment services consists of fees earned from asset management, trust administration, and investment advisory services, and through facilitating securities transactions. Performance obligations for asset management and trust administration services are satisfied on a monthly or quarterly basis at a transaction price based on a percentage of the period-end market value of the assets under administration. Payment for asset management and trust administration services is generally received a few days after period-end through a direct charge to the customers’ accounts. Performance obligations for investment advisory services are satisfied over the period in which the services are provided through a time-based measurement of progress, and the agreed-upon transaction price with the customer varies depending on the nature of the services performed. Performance obligations for facilitating securities transactions are satisfied at a point-in-time when the securities are sold at a transaction price that is based on a percentage of the contract value. Payment for both investment advisory services and facilitating securities transactions may be received in advance of the service, but generally is received immediately or in the following period, in arrears.

Other Income - Ametros. Other income for the Healthcare Financial Services segment primarily includes revenues recognized in connection with contracts with customers from the acquired Ametros business. The nature of such revenue primarily pertains to income earned from arranging sales of in-network products and services, which is recognized at a point in time. Under the terms of these arrangements, the Company has determined that it acts in the capacity as an agent and, therefore, records revenue on a net basis. Other income related to Ametros also includes revenues earned from providing post-settlement medical management and compliance services, which are recognized over time.

The Company evaluates its contracts with Ametros customers for material rights, or options, to acquire additional goods or services for free or at a discount. The contracts for post-settlement medical management and compliance services contain renewal options that represent a material right, which is recognized as a separate performance obligation at the inception of the arrangement. The Company allocates the transaction price to material rights using the practical alternative, which allocates the transaction price to the services expected to be provided and the corresponding expected consideration. Material rights are recognized at the time the service is transferred or when the option expires.

In addition, a fixed, non-refundable fee that represents an advance payment for access to future services is initially deferred and subsequently amortized into other income ratably over the estimated life expectancy of the member. During the years ended December 31, 2025, and 2024, $2.0 million and $1.6 million, respectively, of such deferred revenue was recognized in Other income.

Deferred Costs to Obtain Contracts and Deferred Revenue

Contracts with customers generated deferred costs to obtain contracts and deferred revenue of $6.6 million and $25.3 million, respectively, at December 31, 2025, and $3.0 million and $22.8 million, respectively, at December 31, 2024. These balances pertained to contracts with customers from the acquired Ametros business.

Note 22: Commitments and Contingencies

Credit-Related Financial Instruments

In the normal course of business, the Company offers financial instruments with off-balance sheet risk to meet the financing needs of its customers. These transactions include commitments to extend credit, standby letters of credit, and commercial letters of credit, which involve, to varying degrees, elements of credit risk.

The following table summarizes the outstanding amounts of credit-related financial instruments with off-balance sheet risk:

			December 31,
(In thousands)			2025						2024
Commitments to extend credit			$	12,517,384					$	11,630,765
Standby letters of credit			636,811						578,912
Commercial letters of credit			22,421						28,287
Total credit-related financial instruments with off-balance sheet risk			$	13,176,616					$	12,237,964

The Company enters into contractual commitments to extend credit to its customers (i.e., revolving credit arrangements, term loan commitments, and short-term borrowing agreements), generally with fixed expiration dates or other termination clauses and that require payment of a fee. Substantially all of the Company’s commitments to extend credit are contingent upon its customers maintaining specific credit standards at the time of loan funding, and are often secured by real estate or other collateral. Since the majority of the Company’s commitments typically expire without being fully funded, the total contractual amount does not necessarily represent the Company’s future payment requirements.

Standby letters of credit are written conditional commitments issued by the Company to guarantee its customers’ performance to a third party. In the event the customer does not perform in accordance with the terms of its agreement with a third-party, the Company would be required to fund the commitment. The contractual amount of each standby letter of credit represents the maximum amount of potential future payments the Company could be required to make. Historically, the majority of the Company’s standby letters of credit expire without being funded. However, if the commitment were funded, the Company has recourse against the customer. The Company’s standby letter of credit agreements are often secured by cash or other collateral.

Commercial letters of credit are issued to finance either domestic or foreign customer trade arrangements. As a general rule, drafts are committed to be drawn when the goods underlying the transaction are in transit. Similar to standby letters of credit, the Company’s commercial letter of credit agreements are often secured by the underlying goods subject to trade.

Allowance for Credit Losses on Unfunded Loan Commitments

An ACL is recorded under the CECL methodology to provide for the unused portion of commitments to lend that are not unconditionally cancellable by the Company. At December 31, 2025, and 2024, the ACL on unfunded loan commitments was $24.1 million and $22.6 million, respectively.

Litigation

The Company is subject to certain legal proceedings and unasserted claims and assessments in the ordinary course of business. Legal contingencies are evaluated based on information currently available, including advice of counsel and assessment of available insurance coverage. The Company establishes an accrual for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Once established, each accrual is adjusted to reflect any subsequent developments. Legal contingencies are subject to inherent uncertainties, and unfavorable rulings may occur that could cause the Company to either adjust its litigation accrual or incur actual losses that exceed the current estimate, which ultimately could have a material adverse effect, either individually or in the aggregate, on its business, financial condition, or operating results. The Company will consider settlement of cases when it is in the best interests of the Company and its stakeholders. The Company intends to defend itself in all claims asserted against it, and management currently believes that the outcome of these contingencies will not be material, either individually or in the aggregate, to the Company or its consolidated financial position.

Federal Deposit Insurance Corporation Special Assessment

In November 2023, the FDIC issued a final rule implementing a special assessment for certain banks, based on the amount of estimated uninsured deposits reported as of December 31, 2022, to recover losses to the DIF associated with protecting uninsured depositors of Silicon Valley Bank and Signature Bank upon their failure in March 2023. At that time, the special assessment was anticipated to be collected over a total of eight quarterly assessment periods, which began during the second quarter of 2024, at a quarterly rate of 3.36 basis points. The Company’s initial estimate of its total special assessment was $47.2 million as of December 31, 2023.

153

Table of Contents

Throughout 2024, the FDIC increased its related loss estimated to the DIF associated with the Silicon Valley Bank and Signature Bank failures, indicating that the special assessment would be collected for an additional two quarters beyond the initial eight-quarter assessment period at a lower quarterly rate. As a result, during the year ended 2024, the Company accrued an additional $10.3 million towards its estimated special assessment charge.

In December 2025, the FDIC issued an interim final rule to amend the collection of the special assessment to reduce the eighth quarterly assessment rate from 3.36 basis points to 2.97 basis points and remove the additional two quarter assessment periods. In light of this interim final rule, the Company released $10.3 million of its special deposit insurance assessment accrual. At December 31, 2025, the Company’s remaining accrual for its estimated special assessment charge was $5.9 million. The Company continues to monitor the estimated loss attributable to the protection of uninsured depositors at Silicon Valley Bank and Signature Bank, which could impact the amount of its accrued liability.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, under the supervision and with the participation of the Chief Executive Officer (who is our principal executive officer) and Chief Financial Officer (who is our principal financial officer), evaluated the effectiveness of our disclosure controls and procedures, as defined in Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of December 31, 2025. The term “disclosure controls and procedures” means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that as of December 31, 2025, our disclosure controls and procedures were effective.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act). Internal control over financial reporting is a process designed by, or under the supervision of, a company’s principal executive and principal financial officers, or persons performing similar functions, and effected by a company’s Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with GAAP. It includes those policies and procedures that:

1.pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of a company;

2.provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of a company are being made only in accordance with authorizations of management and directors of the company; and

3.provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of a company’s assets that could have a material effect on the financial statements.

Our management conducted an assessment, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer under the oversight of our Board, of the effectiveness of our internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, our management concluded that our internal control over financial reporting was effective at December 31, 2025.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures

Because of its inherent limitations, management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all error and fraud. Any control system, no matter how well designed and operated, is based upon certain assumptions and can provide only reasonable, not absolute, assurance that its objectives will be met. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies or procedures may deteriorate. Further, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within the Company have been detected.

Attestation Report of Independent Registered Public Accounting Firm

The Company’s independent registered public accounting firm, KPMG LLP, has issued an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, which appears below under the heading “Report of Independent Registered Public Accounting Firm.”

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors

Webster Financial Corporation:

Opinion on Internal Control Over Financial Reporting

We have audited Webster Financial Corporation and subsidiaries’ (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements), and our report dated February 27, 2026 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Controls over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
