Independent Bank Corp. (NASDAQ: INDB) boosts Q1 2026 profit as margins expand

Rhea-AI Filing Summary

Independent Bank Corp. reported strong first-quarter 2026 results with higher profitability and stable balance sheet metrics. Net income rose to $79.9 million, or $1.63 per diluted share, up from $75.3 million, or $1.52 per share in the prior quarter. On an operating basis, which excludes merger-related costs, net income was $82.1 million, or $1.68 per diluted share.

The bank’s return on average assets improved to 1.31%, and return on average common equity rose to 9.02%, with operating returns slightly higher. Net interest margin expanded to 3.90%, with adjusted margin at 3.72%, helped by higher asset yields and lower deposit costs. Total assets were $24.8 billion, loans were $18.4 billion, and deposits were $20.1 billion, all essentially flat quarter over quarter.

Capital remains solid, with a common equity tier 1 ratio of 12.87% and tangible book value per share of $47.86 despite repurchasing about 802,000 shares for $63.3 million and increasing the quarterly dividend to $0.64. Asset quality is still sound but showed some pressure as nonperforming loans rose to $96.6 million, or 0.52% of total loans, and criticized and classified commercial loans increased to $575.5 million, or 4.0% of total commercial loans.

Positive

• Strong earnings growth and margins: Q1 2026 net income of $79.9 million and operating EPS of $1.68 were up versus Q4 2025, with net interest margin expanding to 3.90% and adjusted margin to 3.72%, indicating improved core profitability.
• Robust capital return with preserved strength: The company repurchased ~802,000 shares for $63.3 million, raised its quarterly dividend 8.5% to $0.64, and still reported a common equity tier 1 ratio of 12.87% and tangible common equity to tangible assets of 9.86%.

Negative

• Rising problem credits: Nonperforming loans increased to $96.6 million (0.52% of total loans) and criticized and classified commercial loans rose to $575.5 million (4.0% of commercial loans), signaling some deterioration in asset quality.
• Flat to slightly declining balances: Total loans fell 0.4% to $18.4 billion and deposits edged down 0.1% to $20.1 billion, limiting balance sheet-driven growth in the near term.

Insights

Bank equity analyst

Profitability and margin expanded strongly, with only modest asset quality pressure.

Independent Bank Corp. delivered a higher quality earnings mix in Q1 2026. Net income of $79.9 million and operating net income of $82.1 million support diluted EPS of $1.63 GAAP and $1.68 operating, both up versus the prior quarter.

Net interest income was stable at $212.5 million, but the reported net interest margin widened to 3.90%, with adjusted margin at 3.72%. This came from modestly higher loan and securities yields and a 10-basis-point decline in total deposit costs to 1.36%, improving spread despite a flat loan book.

Credit metrics remain acceptable, though trending weaker. Nonperforming loans increased to $96.6 million (0.52% of loans), and criticized and classified commercial loans rose to $575.5 million (4.0% of commercial loans). The allowance stayed at 1.03% of total loans, and net charge-offs were low at $4.8 million. Capital strength is notable, with a common equity tier 1 ratio of 12.87% and tangible common equity to tangible assets at 9.86% even after $63.3 million of buybacks and an 8.5% dividend increase.

6 terms

net interest margin financial

"The Company’s net interest margin of 3.90% increased 13 basis points compared to the prior quarter"

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

tangible book value per share financial

"Tangible book value per share of $47.86 at March 31, 2026 grew by $0.31 from the prior quarter"

Tangible book value per share is the company's total physical and financial assets minus its liabilities and intangible items (like goodwill and brand value), divided by the number of outstanding shares. It gives investors a conservative, per‑share estimate of what would remain if the business sold only its hard assets and paid its debts—useful for judging whether a stock is priced above or below its underlying, tangible worth, like valuing a property by its bricks and cash rather than its reputation.

nonperforming loans financial

"Nonperforming loans increased to $96.6 million at March 31, 2026, as compared to $83.6 million at December 31, 2025"

Nonperforming loans are loans on which borrowers have stopped making the scheduled interest or principal payments for an extended period (commonly 90 days or more) or are otherwise in serious danger of default. Think of them as IOUs that aren’t being repaid: they tie up a lender’s money, reduce future interest income, and force the lender to hold extra reserves or take losses. For investors, a rising share of nonperforming loans signals weakening credit quality, higher potential losses, and greater risk to a bank’s profitability and capital.

criticized and classified commercial loans financial

"Total criticized and classified commercial loans of $575.5 million, or 4.0% of total commercial loans, increased $102.7 million"

tangible common equity to tangible assets ratio financial

"The Company’s ratio of tangible common equity to tangible assets of 9.86% at March 31, 2026 represented a decrease of 2 basis points"

Tangible common equity to tangible assets ratio measures how much of a company’s physical, measurable assets are funded by the pure ownership stake of common shareholders after removing intangible items like goodwill and patents. Investors use it like a safety cushion gauge: a higher ratio means more real, recoverable value backing assets and greater capacity to absorb losses, while a lower ratio suggests higher leverage or reliance on non-physical value.

merger and acquisition expenses financial

"The Company incurred merger and acquisition expenses of $3.0 million in the first quarter of 2026"

Rockland, Massachusetts (April 16, 2026) - Independent Bank Corp. (Nasdaq Global Select Market: INDB), parent of Rockland Trust Company, today announced 2026 first quarter net income of $79.9 million, or $1.63 per diluted share, as compared to 2025 fourth quarter net income of $75.3 million, or $1.52 per diluted share.

BALANCE SHEET

Total assets of $24.8 billion at March 31, 2026 decreased $129.3 million, or 0.5%, compared to the prior quarter, driven primarily by decreased loan and cash balances.

Total loans of $18.4 billion at March 31, 2026 decreased $78.3 million, or 0.4%, compared to the prior quarter:

•The commercial and industrial portfolio grew $39.7 million, or 0.9% (3.5% annualized), despite runoff of $38.7 million attributable to the Company’s strategic exit from the dealer finance business.

•Commercial real estate and construction decreased $89.6 million, or 0.9%, due to elevated payoffs and amortization of balances, including a reduction of $55.9 million in the Company’s office portfolio.

•The total consumer portfolio decreased $28.3 million, or 0.7%, primarily attributable to a decline in the residential real estate portfolio of $31.3 million, or 1.1%, reflecting lower seasonal volume compared to the prior quarter. This decrease was partially offset by a modest increase in the home equity portfolio of $10.1 million, or 0.8% (3.2% annualized).

Total deposits decreased by $29.3 million, or 0.1%, to $20.1 billion at March 31, 2026, as compared to the prior quarter:

•Average deposits decreased $309.9 million, or 1.5%, compared to the prior quarter, driven primarily by seasonality in business operating balances.

•Overall core deposits comprised 83.8% of total deposits at March 31, 2026, as compared to 83.7% at December 31, 2025.

•Total noninterest bearing demand deposits were 28.0% and 27.8% of total deposits at March 31, 2026 and December 31, 2025, respectively.

•The total cost of deposits for the first quarter of 1.36% reflected a decrease of 10 basis points compared to the prior quarter.

Total period end borrowings decreased by $49.6 million, or 6.0%, during the first quarter of 2026, reflecting approximately $100 million in net paydowns on Federal Home Loan Bank borrowings, partially offset by $50 million advanced on a working capital line of credit.

The Company’s total securities portfolio of $3.4 billion increased by $62.4 million, or 1.9% (7.6% annualized), from the prior quarter:

•New purchases of $168.4 million in the available for sale portfolio were partially offset by maturities, calls, and paydowns in the combined available for sale and held to maturity portfolios during the quarter.

•Total securities represented 13.6% and 13.3% of total assets at March 31, 2026 and December 31, 2025, respectively.

2

Stockholders’ equity at March 31, 2026 decreased $23.7 million, or 0.7%, compared to December 31, 2025, as strong earnings were offset by the impact of share repurchases, dividends, and unrealized losses on available for sale securities recognized in other comprehensive income during the quarter:

•During the first quarter of 2026, the Company executed on its previously announced $150 million stock repurchase plan, buying back approximately 802,000 shares of common stock for $63.3 million at an average price per share of $78.85.

NET INTEREST INCOME

Net interest income of $212.5 million for the first quarter of 2026 was flat compared to the prior quarter:

•The net interest margin of 3.90% increased 13 basis points when compared to the prior quarter, benefitting from fixed rate asset repricing, lower deposit costs, and 17 basis points of purchase accounting accretion in the first quarter of 2026 as compared to 11 basis points in the prior quarter. Excluding purchase accounting accretion and other non-core items, the adjusted margin of 3.72%(1) increased 8 basis points.

•Total loan yields increased 3 basis points to 5.77% from 5.74%, driven primarily by fixed rate loan repricing and purchase accounting accretion, partially offset by the full quarter impact of Federal Reserve rate cuts made during the fourth quarter of 2025. Similarly, securities yields increased 12 basis points to 3.08% for the current quarter as compared to the prior quarter.

•The Company’s overall cost of funding decreased 8 basis points to 1.52% for the first quarter of 2026 as compared to 1.60% for the prior quarter, driven by a 10 basis point reduction in total cost of deposits.

NONINTEREST INCOME

Noninterest income of $40.3 million for the first quarter of 2026 represented a decrease of $1.2 million, or 2.9%, as compared to the prior quarter. Significant changes in noninterest income for the first quarter of 2026 compared to the prior quarter included the following:

•Interchange and ATM fees decreased by $363,000, or 6.7%, driven by seasonally lower transaction volumes.

•Overall investment and advisory income increased $372,000, or 2.7%, driven primarily by higher asset based fee revenue and insurance commissions compared to the prior quarter. Total assets under administration remained consistent at $9.2 billion as of March 31, 2026.

•Loan level derivative income decreased by $322,000, or 26.1%, reflecting volatility in customer demand.

3

•Other noninterest income decreased by $1.1 million, or 13.8%, driven primarily by a decrease in investment income on equity securities.

NONINTEREST EXPENSE

Noninterest expense of $142.9 million for the first quarter of 2026 represented a decrease of $11.5 million, or 7.4%, as compared to the prior quarter. Significant changes in noninterest expense for the first quarter of 2026 compared to the prior quarter included the following:

•The Company incurred merger and acquisition expenses of $3.0 million in the first quarter of 2026, compared to $12.3 million in the fourth quarter of 2025, all of which were related to the Company’s acquisition of Enterprise. The majority of the 2026 first quarter merger expenses related to final severance payments, and vendor and systems contract terminations.

•Salaries and employee benefits decreased by $843,000, or 1.0%, driven primarily by decreased incentive compensation, retirement benefits, and lower base salaries, partially offset by higher payroll taxes and medical plan insurance.

•Occupancy and equipment expenses increased by $1.7 million, or 10.9%, driven primarily by a $1.9 million increase in snow removal costs for the first quarter of 2026.

•FDIC assessment decreased $731,000, or 18.0%, due to quarterly timing differences.

•Other noninterest expense decreased by $2.4 million, or 7.8%, driven primarily by decreases in consultant fees of $790,000, legal fees of $755,000, and net valuation decreases on equity securities of $384,000.

TAX RATE

The Company’s quarterly effective tax rate increased to 23.38% for the first quarter of 2026 from 20.54% for the prior quarter, due to one-time discrete adjustments combined with revised estimates based on full year results in the prior quarter.

ASSET QUALITY

During the first quarter, the Company’s key asset quality activity and metrics were as follows:

•Nonperforming loans increased to $96.6 million at March 31, 2026, as compared to $83.6 million at December 31, 2025, representing 0.52% and 0.45% of total loans, respectively.

•any unexpected material adverse changes in the Company’s operations or earnings.

The Company cautions readers not to place undue reliance on any forward-looking statements as the Company’s business and its forward-looking statements involve substantial known and unknown risks and uncertainties described above and in the Company’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports

6

on Form 10-Q (“Risk Factors”). Except as required by law, the Company disclaims any intent or obligation to update publicly any such forward-looking statements, whether in response to new information, future events or otherwise. Any public statements or disclosures by the Company following this release which modify or impact any of the forward-looking statements contained in this release will be deemed to modify or supersede such statements in this release. In addition to the information set forth in this press release, you should carefully consider the Risk Factors.

This press release and the appendices attached to it contain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This information may include operating net income and operating earnings per share (“EPS”), operating return on average assets, operating return on average common equity, operating return on average tangible common equity, adjusted net interest margin (“adjusted margin”), tangible book value per share and the tangible common equity ratio.

Operating net income, operating EPS, operating return on average assets, and operating return on average common equity exclude items that management believes are unrelated to the Company’s core banking business such as merger and acquisition expenses, and other items, if applicable. Management uses operating net income and related ratios and operating EPS to measure the strength of the Company’s core banking business and to identify trends that may to some extent be obscured by such items. Management reviews its adjusted margin to determine any items that may impact the net interest margin that may be one-time in nature or not reflective of its core operating environment, such as significant purchase accounting adjustments or other adjustments such as nonaccrual interest reversals/recoveries and prepayment penalties. Management believes that adjusting for these items to arrive at an adjusted margin provides additional insight into the operating environment and how management decisions impact the net interest margin.

Management also supplements its evaluation of financial performance with analysis of tangible book value per share (which is computed by dividing stockholders’ equity less goodwill and identifiable intangible assets, or “tangible common equity,” by common shares outstanding), the tangible common equity ratio (which is computed by dividing tangible common equity by “tangible assets,” defined as total assets less goodwill and other intangibles), and return on average tangible common equity (which is computed by dividing net income by average tangible common equity). The Company has included information on tangible book value per share, the tangible common equity ratio and return on average tangible common equity because management believes that investors may find it useful to have access to the same analytical tools used by management.  As a result of merger and acquisition activity, the Company has recognized goodwill and other intangible assets in conjunction with business combination accounting principles.  Excluding the impact of goodwill and other intangibles in measuring asset and capital values for the ratios provided, along with other bank standard capital ratios, provides a framework to compare the capital adequacy of the Company to other companies in the financial services industry.

These non-GAAP measures should not be viewed as a substitute for operating results and other financial measures determined in accordance with GAAP. An item which management excludes when computing these non-GAAP measures can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP performance measures, including operating net income, operating EPS, operating return on average assets, operating return on average common equity, adjusted margin, tangible book value per share and the tangible common equity ratio, are not necessarily comparable to non-GAAP performance measures which may be presented by other companies.

(1) The total amount of adjustment to present interest income and yield on a fully tax-equivalent basis was $1.5 million, $1.4 million, and $1.1 million for the three months ended March 31, 2026, December 31, 2025, and March 31, 2025, respectively, determined by applying the Company’s marginal tax rates in effect during each respective quarter.
(2) Interest rate spread represents the difference between weighted average yield on interest-earning assets and the weighted average cost of interest-bearing liabilities.
(3) Net interest margin represents annualized net interest income as a percentage of average interest-earning assets.
(4) Interest paid amounts within the savings and interest checking and money market categories for the three months ended December 31, 2025 vary from amounts previously reported in the Company’s fourth quarter 2025 earnings release. These reported amounts reflect a reclassification of approximately $3.0 million in interest paid from the money market category to the savings and interest checking category. The corresponding yields presented above have also been revised to reflect this reclassification.

16 This presentation contains certain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations and business of the Company. These statements may be identified by such forward-looking terminology as “expect,” “achieve,” “plan,” “believe,” “outlook,” “projected,” “future,” “positioned,” “continued,” “will,” “would,” “potential,” “anticipated,” “guidance,” “target” or similar statements or variations of such terms. Actual results may differ from those contemplated by these forward-looking statements. Factors that may cause actual results to differ materially from those contemplated by such forward-looking statements include, but are not limited to: • adverse economic conditions in the regional and local economies within the New England region and the Company’s market area; • events impacting the financial services industry, including high profile bank failures, and any resulting decreased confidence in banks among depositors, investors, and other counterparties, as well as competition for deposits and significant disruption, volatility and depressed valuations of equity and other securities of banks in the capital markets; • the effects to the Company of an increasingly competitive labor market, including the possibility that the Company will have to devote significant resources to attract and retain qualified personnel; • political and policy uncertainties, changes in U.S. and international trade policies, such as tariffs or other factors, and the potential impact of such factors on the Company and its customers, including the potential for decreases in deposits and loan demand, unanticipated loan delinquencies, loss of collateral and decreased service revenues; • the instability or volatility in financial markets and unfavorable domestic or global general economic, political or business conditions, including international conflicts and hostilities, such as the ongoing conflict involving Israel, the U.S. and Iran; • unanticipated loan delinquencies, loss of collateral, decreased service revenues, and other potential negative effects on the Company’s local economies or the Company’s business caused by adverse weather conditions and natural disasters, changes in climate, public health crises or other external events and any actions taken by governmental authorities in response to any such events; • adverse changes or volatility in the local real estate market; • changes in interest rates and any resulting impact on interest earning assets and/or interest bearing liabilities, the level of voluntary prepayments on loans and the receipt of payments on mortgage-backed securities, decreased loan demand or increased difficulty in the ability of borrowers to repay variable rate loans; • risks related to the Company’s acquisition activities, including disruption to current plans and operations; difficulties in customer and employee retention; fees, expenses and charges related to these transactions being significantly higher than anticipated; impairment of goodwill and/or other intangibles; and the Company’s inability to achieve expected revenues, cost savings, synergies, and other benefits at levels or within the timeframes originally anticipated; • the effect of laws, regulations, new requirements or expectations, or additional regulatory oversight in the highly regulated financial services industry, and the resulting need to invest in technology to meet heightened regulatory expectations, increased costs of compliance or required adjustments to strategy; • changes in trade, monetary and fiscal policies and laws, including interest rate policies of the Board of Governors of the Federal Reserve System; • higher than expected tax expense, including as a result of failure to comply with general tax laws and changes in tax laws; • increased competition in the Company’s market areas, including competition that could impact deposit gathering, retention of deposits and the cost of deposits, increased competition due to the demand for innovative products and service offerings, and competition from non-depository institutions which may be subject to fewer regulatory constraints and lower cost structures; • a deterioration in the conditions of the securities markets; • a deterioration of the credit rating for U.S. long-term sovereign debt or uncertainties surrounding the federal budget; • inability to adapt to changes in information technology, including changes to industry accepted delivery models driven by a migration to the internet as a means of service delivery, including any inability to effectively implement new technology-driven products, such as artificial intelligence (“AI”); • electronic or other fraudulent activity within the financial services industry, especially in the commercial banking sector; • adverse changes in consumer spending and savings habits; • the effect of laws and regulations regarding the financial services industry, including the need to invest in technology to meet heightened regulatory expectations or the introduction of new requirements or expectations resulting in increased costs of compliance or required adjustments to strategy; • changes in laws and regulations (including laws and regulations concerning taxes, banking, securities and insurance) generally applicable to the Company’s business and the associated costs of such changes; • the Company’s potential judgments, claims, damages, penalties, fines and reputational damage resulting from pending or future litigation and regulatory and government actions; • changes in accounting policies, practices and standards, as may be adopted by the regulatory agencies as well as the Public Company Accounting Oversight Board, the Financial Accounting Standards Board, and other accounting standard setters; • operational risks related to the Company and its customers’ reliance on information technology; cyber threats, attacks, intrusions, and fraud; and outages or other issues impacting the Company or its third party service providers which could lead to interruptions or disruptions of the Company’s operating systems, including systems that are customer facing, and adversely impact the Company’s business; • risks related to the development and use of AI by the Company, its third-party vendors, clients and counterparties; and • any unexpected material adverse changes in the Company’s operations or earnings. The Company cautions readers not to place undue reliance on any forward-looking statements as the Company’s business and its forward-looking statements involve substantial known and unknown risks and uncertainties described above and in the Company’s most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q (“Risk Factors”). Except as required by law, the Company disclaims any intent or obligation to update publicly any such forward-looking statements, whether in response to new information, future events or otherwise. Any public statements or disclosures by the Company following this release which modify or impact any of the forward-looking statements contained in this release will be deemed to modify or supersede such statements in this release. In addition to the information set forth in this earnings presentation, you should carefully consider the Risk Factors. Forward Looking Statements

17 This presentation contains financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This information may include operating net income and operating earnings per share (“EPS”), operating return on average assets, operating pre-provision net revenue return on average assets, operating return on average common equity, operating return on average tangible common equity, operating noninterest expense, adjusted net interest margin (“adjusted NIM” or “adjusted margin”) and the associated adjusted loan yield, tangible book value per share, tangible common equity ratio and return on average tangible common equity. Management reviews its adjusted margin to determine any items that may impact the net interest margin that may be one-time in nature or not reflective of its core operating environment, such as low-yielding loans originated through government programs in response to the pandemic, or significant purchase accounting adjustments, or other adjustments such as nonaccrual interest reversals/recoveries and prepayment penalties. Management believes that adjusting for these items to arrive at an adjusted margin provides additional insight into the operating environment and how management decisions impact the net interest margin. Management also supplements its evaluation of financial performance with analysis of tangible book value per share (which is computed by dividing stockholders’ equity less goodwill and identifiable intangible assets, or “tangible common equity,” by common shares outstanding), the tangible common equity ratio (which is computed by dividing tangible common equity by “tangible assets,” defined as total assets less goodwill and other intangibles), and return on average tangible common equity (which is computed by dividing net income by average tangible common equity). The Company has included information on tangible book value per share, the tangible common equity ratio and return on average tangible common equity because management believes that investors may find it useful to have access to the same analytical tools used by management. As a result of merger and acquisition activity, the Company has recognized goodwill and other intangible assets in conjunction with business combination accounting principles. Excluding the impact of goodwill and other intangibles in measuring asset and capital values for the ratios provided, along with other bank standard capital ratios, provides a framework to compare the capital adequacy of the Company to other companies in the financial services industry. These non-GAAP measures should not be viewed as a substitute for operating results and other financial measures determined in accordance with GAAP. An item which management excludes when computing these non-GAAP measures can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP performance measures, including operating net income, operating EPS, operating return on average assets, operating pre-provision net revenue return on average assets, operating return on average common equity, operating return on average tangible common equity, operating noninterest expense, adjusted margin, tangible book value per share and the tangible common equity ratio, are not necessarily comparable to non-GAAP performance measures which may be presented by other companies.
