PART I

Item 1. Business

INTRODUCTION

Company Overview

American Coastal Insurance Corporation (referred to in this Form 10-K as we, our, us, the Company or ACIC) is a holding company primarily engaged in the commercial property and casualty insurance business with investments in the United States. On July 10, 2023, we changed our corporate name from United Insurance Holdings Corp. to American Coastal Insurance Corporation. We conduct our business principally through our wholly owned insurance subsidiary, American Coastal Insurance Company (AmCoastal). The Company also previously wrote insurance outside of Florida through Interboro Insurance Company (IIC); however, on April 1, 2025, the Company completed the sale of IIC. The details of this transaction are described below. Collectively, we refer to the holding company and all our subsidiaries, including non-insurance subsidiaries, as “American Coastal Insurance Corporation,” which is the preferred brand identification for our Company.

Our Company’s revenue is generated from writing insurance in Florida. Our target market in such areas consists of states where the perceived threat of natural catastrophe has caused large national insurance carriers to reduce their concentration of policies. We believe an opportunity exists for ACIC to write profitable business in such areas. In 2023, our former insurance subsidiary that wrote personal residential business in six states, United Property & Casualty Insurance Company (UPC) was placed into receivership with the Florida Department of Financial Services (the "DFS"), which divested our ownership of UPC. The results of this subsidiary for periods prior to receivership, now included within discontinued operations, can be seen in Note 4 of the Notes to Consolidated Financial Statements below. Discussion of 2023 and 2024 related to UPC can be found in our 2023 and 2024 Forms 10-K.

We have historically grown our business through strong organic growth, complemented by strategic acquisitions and partnerships, including our acquisitions of AmCo Holding Company, LLC (AmCo) and its subsidiaries, including AmCoastal, in April 2017.

On May 9, 2024, we entered into a Stock Purchase Agreement (the "Sale Agreement") with Forza Insurance Holdings, LLC (Forza) in which ACIC agreed to sell and Forza agreed to acquire 100% of the issued and outstanding stock of IIC. Forza’s application to acquire IIC was approved by the New York Department of Financial Services ("NYDFS") on February 13, 2025, and the sale closed on April 1, 2025. The Company received cash proceeds totaling $25,679,000 from the sale resulting in a loss on disposal of $247,000, net of tax impacts. The Company also recognized a $1,348,000 loss, net of tax impacts, on IIC's fixed maturity portfolio, which was included in accumulated other comprehensive loss on the Company's Consolidated Balance Sheets prior to the sale. As a result, IIC results of operations and assets and liabilities are captured within discontinued operations and can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

Financial strength or stability ratings are important to insurance companies in establishing their competitive position and may impact an insurance company’s ability to write policies. We are rated by Demotech and Kroll Bond Rating Agency (Kroll). Demotech maintains a letter-scale financial stability rating system ranging from A’’ (A double prime) to L (licensed by insurance regulatory authorities). Kroll maintains a letter-scale financial strength rating system for insurance companies ranging from AAA (extremely strong operations and no risk) to R (operating under regulatory supervision). The financial strength or stability ratings of our insurance company subsidiary as of December 31, 2025 are listed below. With these ratings, we expect our property insurance policies will be acceptable to the secondary mortgage marketplace and mortgage lenders.

Our Strategy

Our vision is to be a top-quartile underwriter of catastrophe-exposed property insurance. Our plan is to focus primarily on low-rise commercial property insurance in Florida. We write our condominium product through our exclusive managing general agency agreement and long-term partnership with AmRisc. In addition, in 2025 we began writing our apartment and assisted living products through our affiliated managing general agency Skyway Underwriters. The Company’s continuous portfolio optimization process strives to balance our risk appetite and underwriting profit opportunities with our available capital and reinsurance capacity to achieve consistent and sustainable underwriting profitability for the Company and its reinsurers over time.

5

AMERICAN COASTAL INSURANCE CORPORATION

We desire to have the right combination of price, underwriting rules, deductibles and coverages to earn a return on capital that exceeds our cost of capital throughout the insurance market cycle. The Company also seeks to have risks maintain an appropriate insurance to value through re-underwriting and inspections of each property every three years to ensure it meets or exceeds our underwriting guidelines with verified data quality and integrity regarding the key risk characteristics of our covered properties.

PRODUCTS AND DISTRIBUTION

Commercial Residential Products

We provide commercial multi-peril property insurance for residential condominium associations, apartments and assisted living facilities in Florida. We include coverage to policyholders for loss or damage to buildings, inventory or equipment caused by covered causes of loss such as fire, wind, hail, water, theft and vandalism.

Not-At-Risk Offerings

On our equipment breakdown, identity theft, and flood policies we earn a commission while retaining no risk of loss, since all such risk is ceded to other private companies (other risks).

Underwriting

We price our products at levels that we project will generate an acceptable underwriting profit. We aim to accurately underwrite the risk and profitability of each potential policy. The Company uses pricing algorithms, judgment-based rating and consent to rate methodologies that consider historical attritional loss costs for the rating territory in which the risk resides, as well as modeled expected losses for catastrophes and projected reinsurance costs based on the specific geographic and structural characteristics of the property. We seek to optimize our portfolio by managing our probable maximum loss (PML), total insured value (TIV) and average annual loss (AAL). As a part of this optimization process, we use the output from third-party modeling software to analyze our risk exposures, including wind exposures, by zip code or street address. We also utilize AI technology to assist with the intake process and the underwriting evaluation process (including both guidelines and building characteristics).

We measure our underwriting profitability by the combined ratio, which is a sum of the ratios of losses, loss adjustment expenses, and underwriting expenses to either gross or net earned premiums. A combined ratio under 100% indicates an underwriting profit. Refer to Management’s Discussion and Analysis of Financial Condition and Results of Operations in Part II, Item 7 of this report for further details on our combined ratio.

Distribution Channels

Our condominium policies are marketed and distributed by AmRisc through a network of independent agencies managed by AmRisc that specialize in commercial residential insurance. AmRisc is an unaffiliated third party and represents 100% of our condominium revenue based on our exclusive agreement in Florida.

Our apartment and assisted living facility policies are marketed and distributed by Skyway Underwriters through multiple wholesaler partners that specialize in commercial residential insurance. These wholesalers represented 100% of our apartment and assisted living facility revenue.

The Company believes wholesale partners build relationships in their communities that can lead to profitable business and policyholder satisfaction. We believe we have built significant credibility and loyalty with the wholesale communities in Florida through (i) our frequent in-depth communications on our products and (ii) our expectations and goals for our relationships with each wholesaler.

Typically, our wholesale partners represent several insurance companies for commercial product lines. We depend on these partners to produce new business for us. We compensate our wholesale partners primarily with fixed-rate commissions that we believe are consistent with those generally prevailing in the market. 100% of our premiums and policies are concentrated in the state of Florida.

COMPETITION

6

AMERICAN COASTAL INSURANCE CORPORATION

The property and casualty insurance market in the United States is highly competitive and rapidly changing. Our primary competitors range from large national property and casualty insurance companies that write most classes of business using traditional products and pricing to small and mid-size regional insurance companies that provide specialty coverages.

We compete primarily on the basis of policy features, the strength of our distribution network and the quality of our services to our partners and policyholders. This pricing segmentation approach allows us to offer products in areas that have a high demand for property insurance yet are under-served by the national carriers. However, we face the risk that policyholders may be able to obtain more favorable terms from competitors rather than renewing coverage with us.

Our ability to compete is dependent on a number of factors. One factor is the financial strength or stability ratings assigned to our insurance subsidiary by independent rating agencies. A downgrade in these ratings could negatively impact our position in the market. Another factor is that we must attract and retain key employees and highly skilled people in order to be successful in the market. There is intense competition in our industry which could lead to higher-than-expected employee turnover or difficulty attracting new employees. Finally, technological advancements and innovation in the insurance industry, including the use of artificial intelligence, provide opportunities for a competitive advantage. Advancements and innovation are being used in all aspects of the industry including digital-based distribution methods, underwriting and claims handling. We continue to leverage the technology that we have and to make substantial investments into new technology in an effort to gain an advantage over our competitors.

REGULATION

We are subject to extensive regulation in the jurisdiction in which our insurance company subsidiary is domiciled and licensed to transact business, primarily at the state level. AmCoastal is domiciled in Florida. In general, these regulations are designed to protect the interests of insurance policyholders.

Such regulations have a substantial effect on certain areas of our business, including:

•insurer solvency,

•reserve adequacy,

•insurance company licensing and examination,

•agent and adjuster licensing,

•rate setting, underwriting rules and coverage forms,

•investments,

•assessments or other surcharges for guaranty funds,

•transactions with affiliates,

•the payment of dividends,

•reinsurance,

•protection of personally identifiable information,

•risk solvency assessment and enterprise risk management,

•cybersecurity,

•statutory accounting methods, and

•numerous requirements relating to other areas of insurance operations, including policy forms, underwriting standards and claims practices.

Our insurance subsidiary provides audited statutory financial statements to the various insurance regulatory authorities. With regard to periodic examinations of an insurance company’s affairs, insurance regulatory authorities, in general, defer to the insurance regulatory authority in the state in which an insurer is domiciled; however, insurance regulatory authorities from any state in which we operate may conduct examinations at their discretion.

In 2023, the FLOIR notified the Company of a statutory financial examination of AmCoastal as of December 31, 2023, which commenced in 2024 and concluded prior to December 31, 2025, with no findings. In 2025, the FLOIR notified the Company of a targeted market conduct examination related to AmCoastal's Hurricane Ian claims handling operations. This concluded prior to

AMERICAN COASTAL INSURANCE CORPORATION

December 31, 2025, and the Company agreed to enter into a Consent Order wherein the Company was fined $400,000 related to the findings of the examination.

For a discussion of statutory financial information and regulatory contingencies, see Note 16 to our Notes to Consolidated Financial Statements in Part II, Item 8 of this report.

Risk-Based Capital Requirements

To enhance the regulation of insurer solvency, the National Association of Insurance Commissioners (NAIC) has published risk-based capital (RBC) guidelines for insurance companies designed to assess capital adequacy and to raise the level of protection statutory surplus provides for policyholders. The guidelines measure three major areas of risk facing property and casualty insurers: (i) underwriting risks, which encompass the risk of adverse loss developments and inadequate pricing; (ii) declines in asset values arising from credit risk; and (iii) other business risks. Most states, including Florida, have enacted the NAIC guidelines as statutory requirements, and insurers having less statutory surplus than required will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy.

The level of required RBC is calculated and reported annually. The table below outlines our subsidiary's RBC ratio, which was in excess of minimum requirements, as of December 31, 2025.

Subsidiary		RBC Ratio
AmCoastal			1,757	%

Underwriting and Marketing Restrictions

During the past several years, various regulatory and legislative bodies have adopted or proposed new laws or regulations to address the cyclical nature of the insurance industry, catastrophic events and insurance capacity and pricing. These regulations: (i) create “market assistance plans” under which insurers are induced to provide certain coverage; (ii) restrict the ability of insurers to reject insurance coverage applications, to rescind or otherwise cancel certain policies in mid-term, and to terminate agents; (iii) restrict certain policy non-renewals and require advance notice on certain policy non-renewals; and (iv) limit rate increases or decrease rates permitted to be charged.

Most states also have insurance laws requiring that rate schedules and other information be filed with the insurance regulatory authority, either directly or through a rating organization with which the insurer is affiliated. The insurance regulatory authority may disapprove a rate filing if it finds that the rates are inadequate, excessive or unfairly discriminatory.

Most states require licensure or insurance regulatory authority approval prior to the marketing of new insurance products. Typically, licensure review is comprehensive and includes a review of a company’s business plan, solvency, reinsurance, rates, forms and other financial and non-financial aspects of a company, such as the character of its officers and directors. The insurance regulatory authorities may prohibit entry into a new market by not granting a license or by withholding approval.

Limitations on Dividends by Insurance Subsidiaries

As a holding company with no significant business operations of our own, we rely on payments from our insurance subsidiary as one of the principal sources of cash to pay dividends and meet our obligations. Our insurance affiliate is regulated as a property and casualty insurance company and its ability to pay dividends is restricted by Florida law.

The state laws of Florida permit an insurer to pay dividends or make distributions out of that part of statutory surplus derived from net operating profit and net realized capital gains or adjusted net investment income. The state laws further provide calculations to determine the amount of dividends or distributions that can be made without the prior approval of the insurance regulatory authorities and the amount of dividends or distributions that would require prior approval of the insurance regulatory authorities in those states. Statutory RBC requirements may further restrict our insurance subsidiary's ability to pay dividends or make distributions if the amount of the intended dividend or distribution would cause statutory surplus to fall below minimum RBC requirements.

For additional information regarding those restrictions, see Part II, Item 5 and Part I, Item 1A of this report.

Insurance Holding Company Regulation

As a holding company of an insurance subsidiary, we are subject to laws governing insurance holding companies in Florida. These laws, among other things: (i) require us to file periodic information with the insurance regulatory authority, including information concerning our capital structure, ownership, financial condition and general business operations; (ii) regulate certain transactions between our affiliates and us, including the amount of dividends and other distributions and the terms of surplus notes: and (iii) restrict the ability of any one person to acquire certain levels of our voting securities without prior regulatory approval. Any purchaser of 5% or more of the outstanding shares of our common stock could be presumed to have acquired control of us unless the insurance regulatory authority, upon application, determines otherwise.

Insurance holding company regulations also govern the amount any affiliate of the holding company may charge our insurance affiliate for services (i.e., management fees and commissions). The Company allocates a portion of relevant expenses to AmCoastal for statutory accounting purposes at cost.

AmRisc, a managing general underwriter, handles the underwriting, claims processing and premium collection for our AmCoastal condominium business written in Florida. In return, AmRisc is reimbursed through monthly management fees.

Skyway Underwriters, our managing general agency, handles the underwriting and premiums collection for our AmCoastal apartment and assisted living business written in Florida. In return, Skyway Underwriters is reimbursed through monthly management fees.

CORPORATE RESPONSIBILITY AND SUSTAINABILITY

As a company with more than 20 years of history and experience, we strive to create and maintain a culture within our business where people are empowered to address risks as they emerge, and where we expect all associates to hold themselves and their teammates accountable for personal integrity and professionalism. To demonstrate this culture our leaders must lead by example and clear standards of behavior should be well understood by the entire company. We maintain five core values; collaboration, communication, loyalty, resiliency, and integrity, to accomplish this goal. These values and the expectations of our people are outlined within our code of conduct, which is reviewed by all team members.

In addition to our cultural goals, we are committed to conducting business in a manner that supports environmental, social, and governance (ESG) matters. ACIC believes that an effective ESG strategy leads to improved decision making, associate engagement, and financial results over time.

To show our commitment to conducting business that supports ESG matters, in the third quarter of 2024 we published our 2024 ESG Highlights, which outlines key decisions and accomplishments made by the Company during 2024. These highlights are available on the Investor Relations page of our company website under “ESG”. Highlights from our Company-wide ESG practices can also be seen below.

Environmental Matters

As a data driven organization, some of the facts surrounding climate change have our attention. Several factors, including the rise in carbon dioxide concentration levels in the atmosphere, higher global mean air and water temperatures, and sea and Arctic ice levels have been identified as potential culprits of the higher frequency and severity of catastrophe losses we have incurred over the past five years.

There is a growing consensus today that the frequency and severity of catastrophic events or severe weather conditions is increasing as a result of climate change. We recognize current trends and potential financial impact are not sustainable. As a result, we have taken the following steps to improve our environmental footprint and reduce our contribution to climate change:

•Reducing waste: paperless policy document delivery option and investment in paperless technologies;

•Eco-friendly disposal of retired equipment and electronics;

•Installed filtered water dispensers throughout our offices to promote re-usable bottles over disposables;

•Utilization of recycling bins throughout our offices;

9

AMERICAN COASTAL INSURANCE CORPORATION

•Maintenance of a hybrid and remote work environment to both enhance productivity and curb the impact of daily commuting; and

•Use of energy-efficient LED lighting, motion-activated lighting, and programmable thermostats to reduce energy use.

ACIC continuously monitors our environmental footprint and will continue to take steps to reduce this footprint where possible. Previously, we made an aspirational commitment to achieve net-zero carbon emissions in our operations and through our value chain by no later than 2030. While we continue to evaluate data and guidance as it becomes clearer, we believe further analysis is necessary and achieving net-zero will take longer than we initially believed. As a result, we may need to change or recalibrate our goals in line with improved data and as climate science, regulatory requirements and market practices regarding standards, methodologies and measurements evolve. Our climate risk analysis and strategy remain under development and subject to evolution over time. As such, as of December 31, 2025, we cannot provide a timeline for achieving a net-zero carbon emission commitment.

Social Responsibility

We understand that research shows diverse teams perform better, innovate more and are more effective at managing risks. As a result, our organization has a vested interest in hiring associates and building teams that reflect the diversity of society and the communities that we seek to serve. Details of our accomplishments creating a diverse and inclusive workplace can be seen in Part I, Item 1. “Human Capital Management”.

In addition to our social responsibility as an employer within the community, ACIC also seeks to support our community through various initiatives intended to give back and promote goodwill. Over the past several years we have provided support to numerous non-for-profit organizations. Some of the causes we have provided support to include, but are not limited to, youth education, work force development, medical care and research, domestic violence shelters and prevention, and child-care services. We are committed to giving back and investing in the communities we serve.

Governance Matters

Our Board of Directors oversee and monitor our management in the interest and for the benefit of our stockholders. Our Board of Directors is currently comprised of nine directors, divided into two classes. Each class of directors is elected for a two-year term, in accordance with our Certificate of Incorporation. Eight of our directors, or 88.9%, are considered to be independent.

Our Board of Directors has several committees, including an Audit Committee, a Compensation and Benefits Committee, a Nominating and Corporate Governance Committee, Risk Management Committee, and an Investment Committee. All members of these committees qualify as independent directors under Securities and Exchange Commission (SEC) and Nasdaq standards, as well as under the independence standards specific to their committees. Our Nominating and Corporate Governance Committee is responsible for oversight of our ESG processes and initiatives. ACIC has also committed to adding at least two new directors to our Board of Directors to improve overall diversity at the highest level of corporate governance.

HUMAN CAPITAL MANAGEMENT

Diversity and Employment Statistics

As of December 31, 2025, we had 68 employees, of which 11 worked in our Claims Department, and 10 worked in our Sales and Underwriting Department, respectively. These employees have regular direct contact with our vendors, agencies, or customers. We are not party to any collective bargaining agreements and we have not experienced any work stoppages or strikes as a result of labor disputes.

The following table shows the diversity in our workforce population at December 31, 2025 and how this diversity has changed from December 31, 2024.

		Gender (1)		Change from December 31, 2024		Race (1)		Change from December 31, 2024
Executive Officers		28.6%		0.0 points		28.6%		0.0 points
Management Team (2)		44.6%		5.7 points		13.9%		7.4 points
All Other Employees		44.0%		7.9 points		12.0%		(10.2) points

(1) Information regarding gender and race is based on information provided by employees.

(2) Our management team is comprised of employees in supervisory roles at the manager and director level or above.

We believe that inclusion and diversity start at the top. In 2021, we appointed a female leader within our organization to serve as our General Counsel. In addition, in January 2024, we appointed a new female leader from outside of our organization to serve as our Chief Financial Officer. Furthermore, AmCoastal appointed two female directors in 2024. With three of the seven members of our executive leadership team as of December 31, 2025 comprised of underrepresented groups, we believe this is strong evidence of our commitment to our ESG goals.

Oversight and Management

We recognize the diversity of our policyholders, team, and geographic markets, and believe in creating an inclusive environment that represents a variety of backgrounds. Working under these principles, our Human Resources Department is tasked with recruiting, hiring, onboarding, performance management, and managing employee-related matters.

We believe in transparency at all levels at ACIC. On a monthly basis, an all-employee meeting is held where our executive officers and senior management recognize employees for their continued success, discuss new and ongoing company initiatives, and address any concerns our employees may have. In addition, the leaders in each department assist our executive officers in maintaining our culture and implementing our core values at all levels of the organization.

Total Rewards

We believe that our future success largely depends upon our ability to attract and retain highly skilled employees. To ensure we are successful in this, we provide our employees with the following:

•Competitive salaries and bonuses;

•Tuition reimbursement;

•Paid parental leave; and

•Robust employee benefit packages that include:

oHealth care;

oVision;

oDental;

oRetirement program;

oPaid time off; and

oEmployee assistance program that provides emotional support, legal services and financial services.

As a part of our retention efforts, we also invest in ongoing development for all employees, and attempt to fill vacant senior or leadership roles through internal promotion when possible. Voluntary attrition was 3.0% for the year ended December 31, 2025.

Item 1A. Risk Factors

Many factors affect our business, financial condition and results of operations, some of which are beyond our control. If any of the following risks or uncertainties occur, our business, financial condition or results of operations may be materially and adversely affected. In that event, the trading price of our securities could decline, and investors could lose all or part of their investment in our securities. Before making an investment in our securities, investors should carefully consider the risk factors discussed below, together with the other information in this report, including the section entitled “Forward-looking Statements” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and the other reports and materials filed by us with the SEC.

RISKS RELATED TO OUR BUSINESS

As a property and casualty insurer, we may experience significant losses, and our financial results may vary from period to period, due to our exposure to catastrophic events and severe weather conditions, the frequency and severity of which could be affected by the unpredictability of future catastrophic events and severe weather conditions.

Our property and casualty insurance operations expose us to risks arising from catastrophes. Catastrophes can be caused by various natural events, including but not limited to hurricanes, tropical storms, tornadoes, windstorms, earthquakes, hail, sinkholes, severe winter weather and fires, or man-made events, such as terrorist attacks (including those involving nuclear, biological, chemical or radiological events), cybercrimes or consequences of war or political instability. We may incur catastrophe losses that exceed the amount of:

•catastrophe losses experienced in prior years;

•catastrophe losses projected to be incurred, using third-party catastrophe modeling software;

•catastrophe loss estimates used to develop prices for our products; or

•our current reinsurance coverage (which would cause us to have to pay such excess losses).

The frequency and severity of weather conditions are inherently unpredictable, but the frequency and severity of property claims generally increase when severe weather conditions occur. We write all of our policies in Florida, a state that has experienced significant hurricanes in recent years, which some weather analysts believe is consistent with a period of sustained greater hurricane activity. There is a growing consensus today that climate change is increasing the frequency and severity of catastrophic events or severe weather conditions which, in addition to the attendant increase in claims-related costs, may also cause an increase in our reinsurance costs and/or negatively impact our ability to provide insurance to our policyholders in the future. In addition, increased catastrophic events could result in increased credit exposure to the reinsurers we transact business with. Our actual losses from catastrophic events may be larger than anticipated should our reinsurers fail to meet their obligations.

We cannot predict how legal, regulatory and social responses to concerns around climate change may impact our business. Governmental entities may also respond to climate change by enacting laws and regulations that may increase our cost of providing insurance in the future, which could adversely affect demand.

Catastrophes could be more frequent or severe than contemplated in our pricing and risk management models, and may have a material adverse effect on our results of operations during any reporting period due to increases in our loss and loss adjustment expense. Catastrophes may also reduce liquidity and could impair our ability to maintain existing capital, or raise capital on acceptable terms or

12

AMERICAN COASTAL INSURANCE CORPORATION

at all. In addition to catastrophes, the accumulation of losses from several smaller weather-related events in any reporting period may have a similar impact to our results of operations and financial condition.

Because we conduct all of our business in Florida, our financial results substantially depend on, and could be adversely affected by, the regulatory, legal, economic, political, demographic, competitive and weather conditions present in that state.

As of December 31, 2025, all of our policies in-force were written in Florida and all of our TIV was in Florida. Therefore, the prevailing regulatory, legal, economic, political, demographic, competitive, weather and other conditions in Florida will have a significant impact on our revenues and profitability. Furthermore, changes in such conditions in Florida could make doing business in Florida less attractive for us, which could have a more pronounced effect on us than it would on other insurance companies that are more geographically diversified.

In addition, due to Florida’s climate, we are subject to increased exposure to certain catastrophic events such as hurricanes, tropical storms and tornadoes, as well as an increased risk of losses from such events. The occurrence of one or more catastrophic events or other conditions affecting losses in Florida may cause a disproportionately adverse effect on our results of operations and financial condition.

Because we rely on insurance agents, the loss of these agent relationships, particularly our relationship with AmRisc, or our inability to attract and incentivize new agents could have an adverse impact on our business.

AmCoastal has a managing agency contract (the MGA contract) with AmRisc, pursuant to which AmRisc serves as AmCoastal’s managing general agent for binding and writing commercial residential property lines for condominium, townhome and homeowners association insurance written in Florida. The contract between AmCoastal and AmRisc is exclusive. Under the MGA contract with AmCoastal, AmRisc must produce a certain volume of business for AmCoastal. Therefore, failure of AmRisc to produce the required volume of business could cause us to lose substantial premiums and could require us to seek one or more alternative managing general agents. If we were unable to find one or more replacement managing general agents, our revenues could decrease, which could have a material adverse effect on our business, financial condition and results of operations. Given the concentration of AmCoastal’s commercial business and operations with AmRisc, AmRisc may have substantial leverage in negotiations with AmCoastal regarding the MGA contract, and amendments to the terms and conditions of the MGA contract or other changes to the commercial relationship between AmRisc and AmCoastal could have a material adverse effect on our business, financial condition and results of operations. Following the termination or expiration of the MGA contract, AmCoastal’s ability to compete for and solicit renewals of business previously underwritten by AmRisc may be limited by legal, commercial and other impediments, including AmRisc’s relationship with other insurance producers that control the business. Such impediments could have a material adverse effect on our financial condition and results of operations due to the concentration of AmCoastal’s business with AmRisc.

As of December 31, 2025, we market our apartment and assisted living insurance products through a network of multiple independent wholesalers. These wholesalers and their brokers own the customer relationships and are not under our direct control. Our contracts restrict us from directly soliciting their policyholders, and most brokers also represent competing insurers. As a result, we must continually compete for their attention and business. Competitors may offer broader product options, lower premiums or higher broker commissions. Consequently, our success depends heavily on the strength of our broker relationships and our ability to offer competitive, well-aligned insurance solutions. Losing any of these wholesale relationships, or failing to attract, retain or motivate new brokers, could negatively impact new business production and retention of in-force policies.

Actual claims incurred may exceed our loss reserves for claims, which could adversely affect our results of operations and financial condition.

Loss reserves represent our estimate of ultimate unpaid losses for claims that have been reported and claims that have been incurred but not yet reported. Loss reserves do not represent an exact calculation of liability, but instead represent our best estimate, generally utilizing actuarial expertise, historical information and projection techniques at a given reporting date.

The process of estimating our loss reserves involves a high degree of judgment and is subject to a number of variables. These variables can be affected by both internal and external events, such as changes in claims handling procedures, economic inflation, legal trends, legislative changes, emerging economic and social trends and varying judgments and viewpoints of the individuals involved in the estimation process, among others. In addition, application of statistical and actuarial methods in estimating our loss reserves may

13

AMERICAN COASTAL INSURANCE CORPORATION

require the adjustment of overall reserves upward or downward from time to time. Future loss experience substantially in excess of our loss reserves could substantially harm our results of operations and financial condition.

Because of the inherent uncertainty in estimating loss reserves, including reserves for catastrophes and litigated claims, additional liabilities resulting from one insured event, or an accumulation of insured events, may exceed our existing loss reserves. If our reserves are inadequate, it may cause us to overstate our earnings for the periods during which our reserves for expected losses were insufficient and result in higher losses in future periods.

We may experience government-levied assessments. Although we may have the ability to collect this assessment from our policyholders, the timing of collection may have a material adverse effect on our results of operations.

Our insurance subsidiary is subject to assessments levied by various governmental and quasi-governmental entities in Florida. For example, in May 2023, Florida enacted a consumer protection law that increased the maximum administrative fines that may be levied on insurance companies by the FLOIR by 250% generally, and 500% for violations stemming from a state of emergency such as a hurricane. While we may have the ability to recover these assessments from policyholders through policy surcharges in Florida, our payment of the assessments and our recoveries may not offset each other in the same reporting period in our financial statements and may have a material adverse effect on our results of operations in a particular reporting period.

We have identified and remediated material weaknesses in our internal control over financial reporting. Our failure to maintain adequate internal controls could have a material adverse effect on our business, financial condition, results of operations and stock price.

“Internal control over financial reporting” refers to those processes within a company that are designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP. Section 404 of the Sarbanes-Oxley Act of 2002 requires our management to annually assess the effectiveness of our internal control over financial reporting. Management concluded that we did not maintain effective internal control over financial reporting as of December 31, 2023; however, this weakness was remediated as of December 31, 2024 as described in more detail in Part II, Item 9A of our 2024 Annual Report on Form 10-K, filed with the SEC on March 10, 2025.

If we fail to maintain adequate internal controls, or if we have future material weaknesses in our internal controls, in each case in accordance with applicable standards, we may be unable to conclude on an ongoing basis that we have effective internal control over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002. Because effective internal controls are necessary for us to produce reliable financial reports, our business, financial condition and results of operations could be harmed, investors could lose confidence in our reported financial information, and the market price for our stock could decline if our internal controls do not remain effective or if future material weaknesses in our internal controls are identified.

If we experience difficulties with our information technology or data security systems and/or outsourcing relationships, our ability to conduct our business could be negatively impacted, which could adversely affect our financial condition or results of operations.

We use computer systems to store, retrieve, evaluate and utilize customer, employee, company and third-party data and information. Our business is highly dependent upon our information technology systems and the ability of key vendors and third-party administrators to perform necessary business functions efficiently and without interruption. Our ability to process policies and adjust claims in a timely manner could be impaired by an unplanned shutdown or failure of one or more systems or facilities due to man-made or natural disruptions. These include an event leading to power outages, loss of facility access, a major internet failure, a pandemic or a failure of one or more of our information technology, telecommunications or other systems. Because our information technology and telecommunications systems interface with and often depend on third-party systems, we could experience service denials if demand for such service exceeds capacity or a third-party system fails or experiences interruption. If sustained or repeated, such a business interruption, system failure or service denial could result in a deterioration of our ability to write and process new and renewal business, provide customer service, pay claims in a timely manner or perform other necessary business functions.

Despite our ongoing evaluation of potential attackers’ techniques and tactics and our efforts in monitoring, training, planning and prevention, there is no assurance that our security measures will provide fully effective protection from information technology disruptions, such as those caused by cyber-attacks, system failures, human error, unauthorized access, natural disasters or malicious software. Because modern technology platforms and the malicious techniques used to obtain unauthorized access or to sabotage systems

14

AMERICAN COASTAL INSURANCE CORPORATION

evolve rapidly, we may be unable to anticipate some techniques or to implement comprehensive counter measures. A material breach in the security of our information technology systems and data could include the theft of our confidential or proprietary information, including trade secrets, and the personally identifiable information of our customers, claimants, agents and employees. From time to time, we experience threats to our data and information technology systems, including system failures, service disruptions and attempts to gain unauthorized access. Disruptions or security breaches resulting in a loss or damage to our data or inappropriate disclosure of proprietary or confidential information, or the personally identifiable information of our customers, claimants, agents and employees, could cause significant damage to our reputation, adversely affect our relationships with our customers, result in litigation or regulatory investigations, increase remediation costs and/or regulatory penalties, and ultimately harm our business. Third parties to whom we outsource certain functions are also subject to the risks outlined above, any one of which may result in our incurring substantial costs and other negative consequences, including a material adverse effect on our business, financial condition and results of operations.

In addition, we may transmit, receive and store personally identifiable, confidential and proprietary information by any number of standard data transmission methods or other electronic means. We may be unable to keep such information confidential in all events, especially with clients, vendors, service providers, counterparties and other third parties who may not have or use appropriate controls to protect confidential information. Furthermore, we are subject to compliance with laws and regulations enacted by U.S. federal and state governments, or enacted by various regulatory organizations or exchanges relating to the privacy and security of the information of clients, employees or others. The compromise of personally identifiable, confidential or proprietary information could result in remediation costs, legal liability, regulatory action and reputational harm.

Additionally, in the absence of overarching federal law, individual states are adopting their own privacy and cybersecurity laws and regulations. For example, in an effort to protect information systems, the NYDFS adopted regulation providing minimum standards for an organization’s cybersecurity program and requiring additional certification confirming compliance. In October 2017, the NAIC adopted a new Insurance Data Security Model Law, which is intended to establish the standards for data security and standards for the investigation and notification of data breaches applicable to insurance licensees in states adopting such law, with provisions that are generally consistent with the NYDFS cybersecurity regulation. In November 2023, NYDFS finalized amendments, effective in April 2024, to expand their cybersecurity regulation by requiring companies to, among other things, (i) establish and maintain a cybersecurity program designed to ensure the confidentiality, integrity and availability of their information systems; (ii) implement and maintain a written cybersecurity policy setting forth policies and procedures for the protection of their information systems and nonpublic information; and (iii) review and update any risk assessments at least annually, as well as whenever a change in the business or technology causes a material change to cyber risk. Though the NYDFS cybersecurity regulation helps to reduce the third-party risk and imposes specific technical safeguards, the evolving compliance and operational requirements of privacy and cybersecurity laws and regulations impose significant costs that are likely to increase over time and may restrict the way services involving data are offered, all of which may adversely affect our business and results of operations.

Furthermore, in recent years the SEC maintained a focus on cybersecurity. In August 2023, the SEC adopted new cybersecurity disclosure rules, aimed at enhancing and standardizing disclosures made by public companies regarding cybersecurity risk management, strategy, governance and incident reporting. Some jurisdictions have also enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data. AmCoastal, in particular, processes sensitive personal information of its policyholders, which exposes AmCoastal to heightened risk. Many regulators have indicated an intention to take more aggressive enforcement actions regarding cybersecurity matters, and private litigation resulting from such matters is increasing and resulting in progressively larger judgments and settlements.

Loss of key vendor relationships, disputes with key vendors, or failure of a vendor to protect personally identifiable information of our customers, claimants or employees, or failure of a vendor to perform its duties in accordance with the contract or the applicable law, could have an adverse effect on our business, results of operations or financial condition.

We rely on services and products provided by many third-party vendors. These include, for example, vendors of computer hardware and software and vendors of services such as claim adjustment services and payroll and benefits vendors who process sensitive personally identifiable information. In the event that one or more of our vendors suffers a bankruptcy, renews its contractual arrangement on terms less favorable to us, fails to comply with legal or regulatory requirements or otherwise becomes unable to continue to provide products or services, or fails to protect personally identifiable information of our customers, claimants or employees, we may suffer operational impairments and financial losses. An interruption in or the cessation of service by any service provider as a result of system failures, capacity constraints, financial difficulties or for any other reason could disrupt our operations, impact our ability to offer certain products and services and result in contractual or regulatory penalties, liability claims from clients or employees, damage to our reputation and harm to our business. Moreover, in the event of a data breach involving any of our third-party vendors, our customers’,

15

AMERICAN COASTAL INSURANCE CORPORATION

claimants’ or employees’ personally identifiable information could also be put at risk. The failure of the third-party vendor to adhere to service level standards, or perform their duties in accordance with applicable law, could impact our financial position. Any such data breach involving our third-party vendors, or failure to perform their duties, could result in significant mitigation or legal expenses for us, which could materially and adversely affect our reputation, relationships with our customers, business, results of operations and financial condition.

Our success has been and will continue to be greatly influenced by our ability to attract and retain the services of senior management, the loss of any of whom could have an adverse effect on our business, financial condition or results of operations.

Our senior executive officers play an integral role in the development and management of our business given their skills, knowledge of our business, years of industry experience and the potential difficulty of promptly finding qualified replacement employees. Due to the intense competition in our industry for senior executive officers with demonstrated ability, we cannot guarantee that any such officers will continue their employment with us. Additionally, we do not maintain any key person life insurance policies on any of our officers or employees. Losing any of our senior executive officers and/or not succeeding in attracting and retaining senior executive officers could have an adverse effect on our results of operations and financial condition.

Our acquisitions, mergers, dispositions and other strategic transactions may not be as successful as we anticipate, and could be difficult to integrate, divert management resources, result in unanticipated costs or dilute our existing stockholders.

Part of our continuing business strategy is to evaluate opportunities to acquire companies or merge with companies that complement our business model or enter into other strategic transactions that facilitate or expedite the accomplishment of our business goals. We may be unable to identify suitable counterparties to such a transaction. Even if we enter into an agreement in respect of an acquisition of another business, merger with another business, disposition of a business or other strategic transaction, we may not be able to finalize a transaction after significant investments of time and resources due to, among other things, a lack of regulatory approval or imposition of a burdensome condition by the regulator.

In connection with an acquisition, merger or other strategic transaction, we could incur debt, amortization expenses related to intangible assets, large and immediate write-offs, assume liabilities or issue stock that would dilute our current stockholders’ percentage of ownership. As a result, there is a risk of transaction-related litigation. Such strategic transactions could pose numerous risks to our operations, including risks relating to:

•incurring substantial unanticipated integration costs;

•diverting significant management attention and financial resources from our other operations and disrupting our ongoing business during the integration process;

•losing key employees, particularly those of the merged operations;

•keeping existing customers and retaining the acquired or merged business’ customers;

•failing to realize the strategic benefits, the potential cost savings or other financial benefits of the acquisitions or mergers;

•incurring unanticipated liabilities or claims from the acquired businesses and contractually-based time and monetary limitations on the seller’s obligation to indemnify us for such liabilities or claims; and

•limitations on our ability to access additional capital when needed.

We are also subject to a certain level of risk regarding the actual condition of the businesses that we acquire or merge with. Until we actually assume operating control of such businesses and their assets and operations, we may not be able to ascertain the actual value or understand the potential liabilities of the acquired or merged entities and their operations. As a result, we may not be able to complete acquisitions, mergers or other strategic transactions or integrate the operations, products or personnel gained through any such acquisition, merger or other strategic transaction without a material adverse effect on our business, financial condition and results of operations.

We face risks associated with investments in which we share ownership or management with third parties.

From time to time, we have and may continue to invest in entities in which we share ownership or management with third parties. In certain circumstances, we may not have complete control over governance, financial reporting, operations, legal and regulatory compliance or other matters relating to such entities. As a result, we may face certain operating, financial, legal, regulatory, compliance and other risks relating to these entities, including, but not limited to, risks related to the financial strength of other investors; the willingness of other investors to provide adequate funding for the entity; differing goals, strategies, priorities or objectives between us and other investors; our inability to unilaterally implement actions, policies or procedures with respect to the entity that we believe are favorable; legal and regulatory compliance risks relating to actions of the entity or other investors; and our inability to resolve disputes with other investors. As a result, investments in which we share ownership or management subject us to risk and may contribute significantly less than anticipated to our earnings and cash flows.

Our Senior Notes place certain restrictions on our operations and our failure to comply with such restrictions, including as a result of events beyond our control, could result in an event of default, which could materially and adversely affect our liquidity, financial condition and results of operations.

Our Senior Notes due 2027 (the "Senior Notes") place certain restrictions on the Company’s financial operations. Because we are a holding company, our assets consist primarily of the securities of our subsidiaries. The negative pledge provisions in the Senior Notes limit our ability to pledge securities of our subsidiaries and restrict dispositions of the capital stock of our subsidiaries. Our Senior Notes require us to maintain certain financial ratios and to comply with various operational and other covenants, including limitations on our ability to incur any indebtedness unless certain conditions are met. Details of these covenants can be found in Note 12 in our Notes to Consolidated Financial Statements. Our failure to comply with such restrictions, including as a result of events beyond our control, could result in an event of default and an acceleration of the maturity of the Senior Notes. We cannot assure you that our assets or cash flow would be sufficient to fully repay the Senior Notes, if accelerated, or that we would be able to restructure the payments on the Senior Notes. This could have a material adverse impact on our liquidity, financial condition and results of operations.

RISKS RELATED TO THE INSURANCE INDUSTRY

Because we are operating in a highly competitive market, we may lack the resources to control our market share, which could adversely impact our business and results of operations.

The property and casualty insurance industry is highly competitive, and we believe it will remain highly competitive for the foreseeable future. The principal competitive factors in our industry are price, service, coverage options, underwriting guidelines, commission structure, rating and financial condition. We compete with other property and casualty insurers that underwrite commercial property and casualty insurance in the same geographic areas in which we operate and some of those insurers have greater financial resources and have a longer operating history than we do. In addition, our competitors may offer products for alternative forms of risk protection that we presently do not offer or are not similarly regulated in the admitted market, which could adversely affect the sales of our products. Customers may turn to our competitors as a result of price, our failure to deliver on customer expectations, service flaws, technology issues, gaps in operational support or other issues affecting customer experience. We also compete with new companies that continue to enter the insurance market. We may have difficulty controlling our market share due to an increase in reinsurance costs, inflation which increases actual losses and loss adjustment expenses, and losses from the high frequency and severity of catastrophe events. Competition could limit our ability to retain existing business or to write new business at adequate rates, and such limitation may cause a material adverse effect on our results of operations and financial position.

In addition, industry developments could further increase competition in our industry. These developments could include:

•an influx of new capital in the marketplace as existing companies attempt to expand their businesses and new companies attempt to enter the insurance business as a result of better market conditions, more competitive premium pricing and/or more favorable policy terms;

•an increase in programs in which state-sponsored entities provide commercial property insurance in catastrophe-prone areas;

•changes in state regulatory climates; and

•the passage of federal proposals for an optional federal charter that would allow some competing insurers to operate under regulations different or less stringent than those applicable to us.

17

AMERICAN COASTAL INSURANCE CORPORATION

These developments and others could make the property and casualty insurance marketplace more competitive by increasing the supply of insurance available. If competition limits our ability to write new business at adequate rates or reduces our policy retention rates, our future results of operations would be adversely affected.

Changes in state regulation may adversely affect our results of operation and financial condition.

As a holding company with an operating insurance company subsidiary, we are subject to the laws and regulations of Florida. From time to time, states pass legislation, and regulators take action, that has the effect of limiting the ability of insurers to manage risk, such as legislation prohibiting insurers from reducing exposures or withdrawing from catastrophe-prone areas, or mandating that insurers participate in residual markets. In addition, legislative initiatives and court decisions can seek to expand insurance coverage for insured losses beyond the original intent of the policies, which could cause our actual loss and loss adjustment expense to exceed our estimates. Further, our ability to adjust pricing to the extent necessary to offset losses or operating costs requires approval of insurance regulatory authorities.

Our ability to appropriately manage our catastrophe exposure by adjusting prices, modifying underwriting terms or reducing exposure to certain geographies may be limited due to considerations of public policy and the evolving political environment, which may have a material adverse effect on our results of operations, financial condition and cash flows. We cannot predict whether and to what extent the adoption of new legislation and regulations would affect our ability to manage our exposure to catastrophic events.

The insurance industry is heavily regulated and further restrictive regulation may reduce our profitability and limit our growth.

The insurance industry is extensively regulated and supervised. Insurance regulatory authorities generally design insurance rules and regulations to protect the interests of policyholders, and not necessarily the interests of insurers, their stockholders, and other investors. This regulation relates to authorization for lines of business, capital and surplus requirements, investment limitations, underwriting limitations, transactions with affiliates, dividend limitations, changes in control, premium rates and a variety of other financial and non-financial components of an insurance company's business. We are subject to comprehensive regulation and supervision by the Office of Insurance Regulation in Florida, the state in which our insurance subsidiary is domiciled and licensed. Florida regulations are unique and complex and subject to change.

We strive to maintain all required licenses and approvals. However, we may not fully comply with the wide variety of applicable laws and regulations. The relevant authority's interpretation of the laws and regulations also may change from time to time. Regulatory authorities have relatively broad discretion to impose fines, and grant, renew or revoke licenses and approvals. If we do not have the required licenses and approvals or do not comply with applicable regulatory requirements, these authorities could preclude or temporarily suspend us from carrying on some or all of our activities or impose substantial fines. In addition, we may face individual and class action lawsuits by insureds and other parties for alleged violations of certain of these laws or regulations.

State statutes and administrative rules generally require each insurance company to register with the department of insurance in its state of domicile and to furnish information concerning the operations of the companies within the holding company system. Failure to comply with such requirements may materially affect the operations, management or financial condition of the insurers. As part of its registration, the insurance company must identify material agreements, relationships and transactions with affiliates, including loans, investments, asset transfers, transactions outside of the ordinary course of business, certain management, service, and cost sharing agreements, reinsurance transactions, dividends, and other financial and non-financial components of an insurer’s business. Florida imposes restrictions or requires prior regulatory approval of specific corporate actions, which may adversely affect our ability to operate, innovate, obtain necessary rate adjustments in a timely manner or grow our business profitably. For example, the FLOIR notified our subsidiary, AmCoastal and its officers and directors, that it was required to show why those officers and directors were not a substantial contributing cause of the insolvency of our former subsidiary, UPC, pursuant to section 624.4073 Fla. Stat., which prohibits officers and directors of insolvent insurers from serving as officers or directors of another insurer unless that officer or director demonstrates that their actions or omissions were not a significant contributing cause of the insolvency. We have been in discussions with the FLOIR and will continue working with the FLOIR on this issue. Our ability to comply with these laws and regulations, and to obtain necessary regulatory action in a timely manner is, and will continue to be, critical to our success.

Currently, the federal government’s role in regulating or dictating the policies of insurance companies is limited. However, from time to time, Congress has considered, and may in the future consider, proposals that would increase the role of the federal government in insurance regulation, either in addition to or in lieu of state regulation. For example, the Dodd-Frank Act established a Federal Insurance Office (FIO) within the U.S. Department of Treasury to collect data on the insurance industry, recommend changes to the state system of insurance regulation and preempt certain state insurance laws. The potential impact on our business as a result of the Dodd-Frank Act and the FIO’s current and future recommendations remains unclear; however, the implementation of any federal insurance regulations that constrain our business opportunities or reduce investment flexibility could negatively impact our business.

In recent years, the state insurance regulatory framework has come under increased federal scrutiny. Changes in federal legislation, regulation and/or administrative policies in several areas, including changes in financial services regulation and federal taxation, could negatively affect the insurance industry and us. In addition, Congress and some federal agencies from time to time investigate the current condition of insurance regulation in the United States to determine whether to impose federal or national regulation or to allow an optional federal charter, which would allow insurance companies to choose to be regulated by state insurance regulations or a single federal regulatory agency, similar to the option available to most banks. Further, the NAIC and state insurance regulators continually reexamine existing laws and regulations, specifically focusing on modifications to holding company regulations, interpretations of existing laws and the development of new laws and regulations. We cannot predict what effect, if any, proposed or future legislation or NAIC initiatives may have on the manner in which we conduct our business.

As part of potential, or future, industry-wide investigations, we may from time to time receive requests for information from government agencies and authorities at the state or federal level. If we are subpoenaed for information by government agencies and authorities, potential outcomes could include law enforcement proceedings or settlements resulting in fines, penalties and/or changes in business practices that could have a material adverse effect on our results of operations. In addition, these investigations may result in changes to laws and regulations affecting the industry.

Changes to insurance laws or regulations, or new insurance laws and regulations, may be more restrictive than current laws or regulations and could significantly increase our compliance costs, which could have a material adverse effect on our results of operations and our prospects for future growth. Additionally, our failure to comply with certain provisions of applicable insurance laws and regulations could result in significant fines or penalties being levied against us and may have a material adverse effect on our results of operations or financial condition.

Our inability to obtain reinsurance on acceptable terms could increase our loss exposure or limit our ability to underwrite policies, which could adversely affect our results of operations and financial condition.

We use, and we expect to continue to use, reinsurance to help manage our exposure to property risks. Reinsurance is insurance for insurers and is fundamentally a promise by the reinsurer to pay possible future claims in exchange for the payment of a premium by the insurance company seeking reinsurance. Both the availability of reinsurance and the cost of reinsurance are subject to prevailing market conditions beyond our control, which can affect business volume and profitability. We may be unable to maintain our current reinsurance coverage, to obtain additional reinsurance coverage in the event our current reinsurance coverage is exhausted by a catastrophic event, or to obtain other reinsurance coverage in adequate amounts or at acceptable rates. Similar risks exist whether we are seeking to replace coverage terminated during the applicable coverage period or to renew or replace coverage upon its expiration. Market conditions beyond our control determine the availability and cost of reinsurance. For example, reinsurance may be more difficult or costly to obtain after several years with higher frequencies of major catastrophes. We may be unable to reduce per event or aggregate retentions when renewing or replacing our coverage due, in part, to the frequency and severity of storms in prior years and the litigation trends in the state of Florida, which would increase our risk exposure and could ultimately lead to us paying higher claims. We provide no assurance that we can obtain sufficient reinsurance to cover losses resulting from one or more storms or other events in the future, or that we can obtain such reinsurance in a timely or cost-effective manner. If we are unable to renew our expiring coverage or to obtain new reinsurance coverage, either our net exposure to risk would increase or, if we are unwilling to accept an increase in net risk exposures, we may have to reduce the amount of risk we underwrite or accept higher reinsurance costs. Any of these alternatives may have a material adverse effect on our results of operations and our financial condition.

Our inability to collect from our reinsurers on our reinsurance claims could have a material adverse effect on our business, results of operation, financial condition and cash flow.

We use reinsurance as a tool to manage risks associated with our business. However, we remain primarily liable as the direct insurer on all risks for which we obtain reinsurance. Our reinsurance agreements do not eliminate our obligation to pay claims to insureds. As a result, we are subject to counterparty risk with respect to our ability to recover amounts due from reinsurers. The risk could arise in two situations: (i) our reinsurers may dispute some of our reinsurance claims based on contract terms, and we may ultimately receive partial or no payment, or (ii) the amount of losses that reinsurers incur related to worldwide catastrophes may materially harm the financial condition of our reinsurers and cause them to default on their obligations. Collectability of reinsurance is subject to the solvency of the reinsurers, interpretation of contract language and other factors. As a result, our exposure to counterparty risk under our reinsurance agreements may have a material adverse effect on our results of operations, financial condition and cash flow. A reinsurer’s insolvency, inability to make payments, or dispute of its obligations under the terms of a reinsurance contract could have a material adverse effect on our business, results of operations, financial condition and cash flow.

Our efforts to manage these risks through underwriting guidelines, collateral requirements, financial strength ratings and other oversight mechanisms may not be successful.

Our success depends on our ability to accurately price the risks we underwrite. Further, failure of any loss limitation methods we employ could have a material adverse effect on our results of operations and financial condition.

Our results of operations and financial condition depend on our ability to underwrite and set premium rates accurately for a wide variety of risks, such as building condition, occupancy and distance to coast. Rate adequacy is necessary to generate sufficient premiums to pay losses, loss adjustment expenses, and underwriting expenses and to earn a profit. While third-party administrators may underwrite on behalf of AmCoastal, we are responsible for setting the criteria under which our vendors operate. We must collect and properly analyze a substantial amount of data, closely monitor and timely recognize changes in trends and models and project both severity and frequency of losses with reasonable accuracy. Our ability to successfully perform these tasks is subject to a number of risks and uncertainties, some of which are outside of our control.

In addition, our underwriting process is generally designed to limit our exposure to known and manageable risks. Various provisions of our policies, such as limitations or exclusions from coverage, which have been negotiated to limit our risks, may not be enforceable in the manner we intend. While our product exclusions and conditions may reduce the loss exposure to us and may eliminate known exposures to certain risks, it is possible that a court or regulatory authority could nullify or void policy exclusions and conditions, or that legislation could be enacted modifying or barring the use of these exclusions and limitations.

Our results of operations and financial conditions could be materially and adversely impacted if any component of our underwriting process does not operate in its intended manner.

We may fail to pay claims accurately and timely, which could adversely affect our results of operations and financial condition.

We rely on internal claims personnel and an unaffiliated third-party claim administration vendor to evaluate and pay claims made under our policies in an accurate and timely manner. Commercial residential policies often cover several structures and result in complex claims. This level of complexity, along with factors such as (i) the accuracy of adjusters as they make their assessments and submit their estimates of damage, (ii) the training, background and experience of our claims representatives, and (iii) the ability of our claims personnel to maintain and update our claims processing procedures as laws and the litigation landscape change, could affect our ability to evaluate and pay claims in an accurate and timely manner. Any failure to pay claims accurately and timely could lead to litigation, undermine our reputation in the marketplace, negatively impact our corporate image and negatively affect our financial results.

Our investments are subject to market risks that may result in reduced returns or losses.

Our investment assets are invested by professional investment management firms under the direction of our management team in accordance with investment guidelines approved by the Investment Committee of the Board of Directors. Our investments are subject to market risks and risks inherent in individual securities. In particular, interest rates are highly sensitive to many factors, including monetary and fiscal policy, domestic and international economic and political issues, geopolitical events, economic sanctions, blockades and other factors beyond our control.

Our portfolio is primarily invested in fixed income securities, and changes in the general interest rate environment will affect our returns on, and the fair value of, our fixed maturity and short-term investments. A decline in interest rates reduces the interest rate payable on new fixed income investments, thereby negatively impacting our net investment income. Conversely, rising interest rates reduce the fair value of existing fixed maturities. The volatility of any losses may force us to liquidate securities, which may cause us to incur capital losses. Realized fixed income and equity losses and unrealized equity losses in our investment portfolio would generally reduce our book value and, if significant, could affect our ability to conduct business. In addition, defaults under, or impairments of, any of these investments as a result of financial problems with the issuer and, where applicable, its guarantor could reduce our net investment income and net realized investment gains or result in investment losses.

We are subject to risks associated with potential declines in credit quality related to specific issuers and a general weakening in the economy. We may experience credit or default losses in our portfolio, including as a result of the failure of the procedures we have implemented to monitor the credit risk of our invested assets, which could adversely affect our results of operations and financial condition.

We may decide to invest an additional portion of our assets in equity securities, private equity limited partnership interests or other investments, which are generally subject to greater volatility than fixed maturity investments. Moreover, our private equity limited partnership interests are subject to transfer restrictions and may be illiquid. General economic conditions, stock market conditions, geopolitical events and many other factors beyond our control can adversely affect the fair value of our equity securities or other investments and could adversely affect our realization of net investment income. As a result of these factors, we may not realize an adequate return on our investments or we may incur losses on sales of our investments, which could reduce our net investment income and net realized investment gains or result in investment losses.

The fair value of our investment portfolio is also subject to valuation uncertainties. The valuation of investments is more subjective when the markets for these investments are illiquid and may increase the risk that the estimated fair value of our investment portfolio is not reflective of prices at which actual transactions would occur. Additionally, in the case of our private equity limited partnership interests, such valuations are determined by outside managers. Since the majority of our investments are held by our insurance subsidiary, significant decreases in the fair value of these investments will produce significant declines in the statutory surplus of our insurance business. A long-term material decline in statutory surplus could have an adverse effect on our financial strength ratings and our ability to write new and renewal insurance business, thus potentially reducing our future underwriting profits.

Our determination of the amount of credit allowances to record varies by investment type and is based upon our periodic evaluation and assessment of known and inherent credit risks associated with the respective investment type. We revise our evaluations and assessments as conditions change and new information becomes available, and we reflect changes in the credit allowance in our Consolidated Statements of Comprehensive Income (Loss). We base our assessment of whether a credit allowance is required, based on our case-by-case evaluation of the underlying reasons for the decline in fair value. However, we may not accurately assess whether a credit allowance is required and the recorded amounts for a credit allowance in our financial statements may be inadequate.

Federal and/or state tax legislation could be enacted that would lessen or eliminate some or all of the tax advantages we currently benefit from, including those governing received deductions and tax credits, which could adversely affect the value of our investment portfolio.

AMERICAN COASTAL INSURANCE CORPORATION

The property and casualty insurance and reinsurance industries are historically cyclical and the pricing and terms for our products may decline, which would adversely affect our profitability.

Historically, the financial performance of the property and casualty insurance and reinsurance industries has been cyclical, characterized by periods of severe price competition and excess underwriting capacity, or “soft” markets, followed by periods of high premium rates and shortages of underwriting capacity, or “hard” markets. We cannot predict with certainty when such a period may occur or how long any given hard or soft market will last. Downturns in the property and casualty market may have a material adverse effect on our results of operations and our financial condition.

Losses from legal actions may materially affect our operating results, cash flows and financial condition.

Trends in the insurance industry regarding claims and coverage issues, such as increased litigation, the willingness of courts to expand covered causes of loss and juries awarding large damage awards, may contribute to increased litigation costs and increase our loss exposure under the policies that we underwrite.

As industry practices and legal, judicial, social and other environmental conditions change, unexpected and unintended issues related to claims and coverage may emerge. Examples of emerging claims and coverage issues include, but are not limited to:

•judicial expansion of policy coverage and the impact of new theories of liability; and

•plaintiffs targeting property and casualty insurers in purported class-action litigation relating to claims-handling and other practices.

Multiparty or class action claims may present additional exposure to substantial economic, non-economic or punitive damage awards. The loss of even one of these claims, if it resulted in a significant award or a judicial ruling that was otherwise detrimental, could create a precedent in our industry that could have a material adverse effect on our results of operations and financial condition. This risk of potential liability may make reasonable settlements of claims more difficult to obtain.

We may be named a defendant in a number of legal actions relating to those emerging claim and coverage issues. The propensity of policyholders and third-party claimants to litigate and the willingness of courts to expand causes of loss and the size of awards may result in increased costs associated with litigation, render our loss reserves inadequate and be material to our operating results and cash flows for a particular quarter or annual period and to our financial condition. In addition, claims and coverage issues may not become apparent to us for some time after our issuance of the affected insurance policies. As a result, we may not know the full extent of liability under insurance policies we issue for many years after the policies are issued.

A downgrade in or withdrawal of our financial strength or stability ratings could adversely impact our business volume and our ability to access additional debt or equity financing.

Financial strength or stability ratings are important to an insurer’s competitive position. Ratings measure an insurance company’s ability to meet its obligation to contract holders and policyholders. High ratings help maintain public confidence in company’s products, facilitate the marketing of its products and enhance the company’s competitive position. Rating agencies review their ratings periodically, and our current ratings may not be maintained in the future. If significant losses, such as those resulting from one or more major catastrophes, or significant reserve additions were to cause our capital position to deteriorate significantly, or if one or more rating agencies substantially increase their capital requirements, we may need to raise equity capital in the future to maintain our ratings or limit the extent of a downgrade. For example, a trend of more frequent and severe weather-related catastrophes may lead rating agencies to substantially increase their capital requirements.

We cannot guarantee that our insurance subsidiary, AmCoastal, will maintain its current A (Exceptional) or higher rating by Demotech. Further, we cannot guarantee that AmCoastal will maintain its A- rating by Kroll. Any downgrade or withdrawal of these ratings could (i) impact the acceptability of our products to condominium associations that are required to buy insurance, or to commercial mortgage lenders that require apartment and assisted living facility owners to buy insurance, (ii) reduce our ability to retain and attract policyholders and wholesalers and (iii) damage our ability to compete, which may have a material adverse effect on our results of operations and financial condition. These material adverse effects could include, but are not limited to:

•reducing demand for new sales of insurance products;

•requiring us to modify our existing products or services, introduce new products or services or reduce prices for our products and services in order to remain competitive;

22

AMERICAN COASTAL INSURANCE CORPORATION

•adversely affecting our relationships with our wholesalers;

•materially increasing the number or amount of policy cancellations and non-renewals by policyholders;

•requiring us to post additional collateral under certain covenants of our financing transactions;

•limiting financial flexibility and access to capital markets;

•adversely affecting our ability to obtain reinsurance at reasonable prices or at all; and

•increasing the interest rates on our outstanding Senior Notes.

RISKS RELATED TO AN INVESTMENT IN OUR COMMON STOCK

Future sales of substantial amounts of our common stock by us or our existing stockholders could cause our stock price to decrease.

As of December 31, 2025, we had registered up to 101 million shares of our securities (including both our preferred and common stock) authorized to issue from time to time in one or more offerings. Additional equity financing or other share issuances by us could adversely affect the market price of our common stock. Future share issuances in connection with merger transactions or other acquisitions could result in substantial additional dilution to our stockholders. If these additional shares are sold, or if it is perceived that they will be sold, into the public market, the price of our common stock could decline substantially.

If we issue additional shares of our common stock or if any of our existing stockholders sells a substantial amount of our common stock, or if the market perceives that such issuance or sales may occur, then the trading price of our common stock may significantly decline.

Dividend payments on our common stock in the future are uncertain, and our ability to pay dividends may be constrained by our holding company structure.

We have paid both ordinary quarterly dividends and special dividends on our common stock in the past, but currently do not pay an ordinary quarterly dividend. The declaration and payment of dividends are at the discretion of our Board of Directors and will be dependent upon our profits, financial requirements and other factors, including legal and regulatory restrictions on the payment of dividends from our subsidiaries (as we are a holding company and do not have any significant operations or assets other than our ownership of the shares of our operating subsidiaries), capital adequacy, liquidity, general business conditions and such other factors as our Board of Directors deems relevant. Therefore, investors who purchase our common stock may only realize a return on their investment if the value of our common stock appreciates.

The ability of our insurance subsidiary to pay dividends may affect our liquidity and ability to meet our obligations.

The Company is a holding company with no significant operations. The principal assets are the stock of its subsidiaries and the holding company’s directly held investment portfolio. State insurance regulatory authorities limit the payment of dividends by our insurance subsidiary, as described in Note 16 in our Notes to Consolidated Financial Statements. The limitations are based on statutory income and surplus. In addition, competitive pressures generally require the subsidiary to maintain an insurance financial strength rating. These restrictions and other regulatory requirements affect the ability of the insurance subsidiary to make dividend payments. Limits on the ability of the insurance subsidiary to pay dividends could adversely affect holding company liquidity, including our ability to pay dividends to stockholders and service our debt in the timeframe expected.

Management views enterprise economic capital as a combination of statutory surplus and invested assets at the parent holding company level. Deterioration in statutory surplus or earnings, from developments such as catastrophe losses, or changes in market conditions or interest rates, could adversely affect holding company liquidity by impacting the amount of dividends from our insurance subsidiary or the utilization of invested assets at the holding company to increase statutory surplus or for other corporate purposes.

The substantial ownership of our common stock by R. Daniel Peed and his affiliates allows him to exert significant control over us, and the Company and R. Daniel Peed are subject to certain restrictive covenants that may restrict our ability to pursue certain opportunities.

R. Daniel Peed, our Executive Chairman of the Board of Directors, beneficially owned approximately 28% of our issued and outstanding common stock at December 31, 2025. Mr. Peed also has a proxy from another member of RDX Holding, LLC, the former

23

AMERICAN COASTAL INSURANCE CORPORATION

parent company of AmCo, who beneficially owns approximately 6% of our issued and outstanding common stock. As a result, Mr. Peed is able to exert substantial control over us. Moreover, Mr. Peed’s interests may conflict with the interests of other holders of our common stock, and he may take actions affecting us with which other stockholders may disagree. Mr. Peed has the ability to exert significant influence over the following:

•the nomination, election and removal of our Board of Directors;

•the adoption of amendments to our charter documents;

•management and policies;

•our day-to-day operations; and

•the outcome of any corporate transaction or other matter submitted to our stockholders for approval, including acquisitions, mergers, consolidations and the sale of all or substantially all of our assets.

AmCo and AmCoastal are also subject to restrictive covenant agreements that contain non-competition, non-solicitation, confidentiality and other restrictive covenants that prohibit AmCo and AmCoastal from engaging in certain activities, including activities customarily performed by managing general agents and activities relating to segments of the commercial property insurance market for coastally exposed risks in the United States.

Transactions by Mr. Peed and his affiliates involving our common stock may have an adverse effect on the price of our common stock.

As noted above, Mr. Peed beneficially owned approximately 28% of our issued and outstanding common stock as of December 31, 2025. The Company has granted Mr. Peed and his affiliates customary demand and piggyback registration rights pursuant to which, subject to certain limitations, all of such shares eligible to be registered under the Securities Act of 1933, as amended (the Securities Act), and may be offered and sold to the public from time to time after the effectiveness of the related registration statement. Such shares may also be resold into the public markets in accordance with an exemption from registration under the Securities Act, including Rule 144, subject to the volume limitations, manner of sale requirements and notice requirements thereof. Sales of our common stock by Mr. Peed and his affiliates could have the effect of lowering our stock price. The perceived risk associated with the possible sale of a large number of shares by these stockholders could cause some of our other stockholders to sell their stock, thus causing the price of our stock to decline. In addition, actual or anticipated downward pressure on our stock price due to actual or anticipated sales of stock by Mr. Peed and his affiliates could cause other institutions or individuals to engage in short sales of our common stock, which may further cause the price of our stock to decline.

Provisions in our charter documents may make it harder for others to obtain control of us even though some stockholders might consider such a development to be favorable.

Our Second Amended and Restated Certificate of Incorporation and Amended and Restated Bylaws contain provisions that may discourage unsolicited takeover proposals our stockholders may consider to be in their best interests. Our Board of Directors is divided into two classes, each of which will generally serve for a term of two years with only one class of directors being elected in each year. At a given annual meeting, only a portion of our Board of Directors may be considered for election. Additionally, the Board of Directors and executive officers control approximately 49% of the common stock of the Company. Consequently, our “staggered board” and concentrated holdings may prevent our stockholders from replacing a majority of our Board of Directors at certain annual meetings and may entrench our management and discourage unsolicited stockholder proposals that may be in the best interests of our stockholders.

Further, our Board of Directors has the ability to designate the terms of and issue one or more series of preferred stock, which may discourage transactions that otherwise could involve payment of a premium over prevailing market prices for our securities.

Item 1C. Cybersecurity

Risk Management and Strategy

Our cybersecurity program is led by our Chief Information Security Officer (CISO) and overseen by the Audit Committee and the Board of Directors. Our cybersecurity program prioritizes threat mitigation, while focusing on maintaining the integrity and resilience

24

AMERICAN COASTAL INSURANCE CORPORATION

of our systems. Our cybersecurity program includes identifying threats, considering potential damages through the lens of residual risk, identifying potential actions to manage cyber risk, implementation, and ongoing monitoring and testing for design and performance effectiveness.

The Company’s risk management strategy identifies cybersecurity risks, such as vulnerabilities on assets, fraud, abuse of systems and services, unauthorized data access, data exfiltration, data destruction, and service disruption, as among the Company’s top enterprise risks. As such, the cybersecurity risk management process and related governance process are integrated into the broader information technology control environment, which is integrated into the Company’s overall risk management systems and processes. Additionally, we regularly review and test our cybersecurity controls.

Our cybersecurity team, in partnership with external vendors and a third-party security operations center, designs and implements data security and cybersecurity programs, risk assessments, monitoring, external and internal penetration tests, controls testing and training for our employees. In 2025, third-party consultants were engaged to perform security penetration tests and to facilitate a table top exercise to test the Company’s cyber incident response plan. We continue to make investments to enhance our ability to identify and detect cybersecurity risks within our environment and protect the Company from those identified risks.

Risk Assessment, Risk Management and Incident Management

We employ people, processes and technologies to proactively address cybersecurity risks. This includes the periodic review and update of IT security policies, employee security awareness training programs complemented by simulated phish testing, and the implementation of firewalls, intrusion prevention and detection systems, anti-malware sensors, and access and identity management controls.

We have established cybersecurity incident response plans, such as the Cybersecurity Incident Response Plan and the IT Disaster Recovery Plan, which outline frameworks for addressing and managing potential cybersecurity incidents. These plans provide direction on departmental responsibilities and collaboration within ACIC, as well as define processes and protocols for incident response and management. The Cybersecurity Incident Response Plan specifies escalation procedures aligned to factors like the severity of the incident, associated risks and harms, necessary mitigation and remediation steps and any relevant legal or regulatory obligations. Multidisciplinary teams handle incident responses and escalate matters to senior management and the Board of Directors when needed. We review and update our cybersecurity incident response plans every year to ensure their effectiveness.

The Company’s risk assessment considers cybersecurity threats associated with the use of third-party service providers. Failure to assess potential risks associated with a third party could expose us to a variety of risks, including, but not limited to supply chain attacks, data breaches, and reputational damage which can have devastating and long-lasting impacts. As such, we have employed contracting policies and procedures which include data protection and other cybersecurity considerations during the vendor onboarding process, and periodic review of service organization controls reports for material third-party service providers.

In the last three fiscal years, we have not experienced a material cybersecurity incident, and we are not aware of any cybersecurity risks that are reasonably likely to materially affect our business other than what is already disclosed in Item 1.A Risk Factors in this Annual Report on Form 10-K. For more information about the risks posed by cybersecurity threats, see “If we experience difficulties with our information technology or data security systems and/or outsourcing relationships, our ability to conduct our business could be negatively impacted, which could adversely affect our financial condition or results of operations” in Item 1A. Risk Factors in this Annual Report on Form 10-K.

AMERICAN COASTAL INSURANCE CORPORATION

management has taken to monitor and control such exposures. The Board of Directors and Audit Committee periodically meet to facilitate oversight of cybersecurity risk.

The Board of Directors regularly devotes time during its meetings to review and discuss the most significant risks facing the Company over the short-, medium- and long-term, and management’s responses to those risks, including cybersecurity. Within these discussions, the Board of Directors receives updates from the CISO on the risks posed by cybersecurity threats and the Company’s cybersecurity program. In addition to evaluating the Company’s cybersecurity risks, the Board of Directors has oversight of management’s cybersecurity function and is responsible for reviewing and approving the Company’s cybersecurity program, as well as reviewing the quality and effectiveness of the Company’s technology security.

Item 2. Properties

We use all of our leased properties for office space. We lease approximately 14,000 square feet of office space located in Florida. These leases are generally medium-term leases of commercial office space.

Item 3. Legal Proceedings

We are involved in routine claims-related legal actions arising in the ordinary course of business. We accrue amounts resulting from claims-related legal actions in unpaid losses and loss adjustment expenses during the period that we determine an unfavorable outcome becomes probable and we can estimate the amounts. Management makes revisions to our estimates based on its analysis of subsequent information that we receive regarding various factors, including: (i) per claim information; (ii) company and industry historical loss experience; (iii) judicial decisions and legal developments in awarding of damages; and (iv) trends in general economic conditions, including the effects of inflation.

On October 20, 2023, the Company received notice that the Florida Department of Financial Services ("DFS") filed a notice of claim and demand for tender of policy limits under the Company's director and officer insurance policy (the “Claim”). The Claim alleges that former officers and directors of UPC were involved in wrongful acts that resulted in UPC's insolvency. The Claim demands immediate tender of the Company's director and officer’s policy limit of $40,000,000 where the Company has a retention of $1,500,000. The former directors and officers of UPC deny the allegations. Although no litigation has arisen from the Claim, litigation is anticipated. The directors and officers plan to vigorously defend against the Claim; however, due to the Company's indemnification obligation, during 2023, the Company accrued the policy retention amount of $1,500,000.

MARKET INFORMATION

Our common stock trades on the Nasdaq Capital Market (Nasdaq) under the symbol “ACIC”.

HOLDERS OF COMMON EQUITY

As of February 27, 2026, we had 7,669 holders of record of our common stock. The number of record holders does not include stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees.

DIVIDENDS

In December 2025, we declared a special cash dividend of $0.75 per share of common stock, which we paid on January 9, 2026 to shareholders of record on January 2, 2026. In December 2024, we declared a special cash dividend of $0.50 per share of common stock, which we paid on January 10, 2025, to shareholders of record on January 2, 2025. Any future dividend payments will be at the discretion of our Board of Directors and will depend upon our profits, financial requirements and other factors, including legal and regulatory restrictions on the payment of dividends, general business conditions and such other factors as our Board of Directors deems relevant.

During the year ended December 31, 2025, the Company received a dividend of $23,000,000 from our insurance subsidiary, AmCoastal. During the year ended December 2024, we received a $14,300,000 dividend from our insurance subsidiary, AmCoastal.

Under Florida law, a Florida-domiciled insurer such as AmCoastal may not pay any dividend or distribute cash or other property to its shareholders except out of its available and accumulated surplus funds, which are derived from realized net operating profits on its business and net realized capital gains. Additionally, a Florida-domiciled insurer may not make dividend payments or distributions to shareholders without the prior approval of the insurance regulatory authority if the dividend or distribution would exceed the larger of:

1.the lesser of:

a.10% of the insurer’s capital surplus, or

b.100% of the insurer’s net income, not including realized capital gains, plus a two-year carryforward

2.10% of the insurer’s capital surplus with dividends payable constrained to unassigned funds minus 25% of unrealized capital gains, or

3.the lesser of:

a.10% of the insurer’s capital surplus, or

b.100% of the insurer’s net investment income plus a three-year carryforward with dividends payable constrained to unassigned funds minus 25% of unrealized capital gains.

Alternatively, AmCoastal may pay a dividend or distribution without the prior written approval of the insurance regulatory authority when:

1.the dividend is equal to or less than the greater of:

a.10% of the insurer’s surplus as to policyholders derived from realized net operating profits on its business and net realized capital gains, or

b.The insurer’s entire net operating profits and realized net capital gains derived during the immediately preceding calendar year, and:

i.The insurer will have surplus as to policyholders equal to or exceeding 115% of the minimum required statutory surplus as to policyholders after the dividend or distribution is made, and

27

AMERICAN COASTAL INSURANCE CORPORATION

ii.The insurer files a notice of the dividend or distribution with the insurance regulatory authority at least ten business days prior to the dividend payment or distribution, and

iii.The notice includes a certification by an officer of the insurer attesting that, after the payment of the dividend or distribution the insurer will have at least 115% of required statutory surplus as to policyholders.

Except as provided above, Florida-domiciled insurers may only pay a dividend or make a distribution (i) subject to prior approval by the insurance regulatory authority, or (ii) 30 days after the insurance regulatory authority has received notice of intent to pay such dividend or distribution and has not disapproved it within such time. As of December 31, 2025, we were in compliance with these requirements.

See Note 16 to our Notes to Consolidated Financial Statements for further discussion of restrictions on future payments of dividends by our insurance affiliates.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes appearing in Part II, Item 8 of this Form 10-K. The following discussion provides an analysis of our results of operations and financial condition for 2025 as compared to 2024. Discussion regarding our results of operations and financial condition for 2024 as compared to 2023 is included in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2024. This discussion and analysis contains forward-looking statements that involve risks, uncertainties and assumptions. Actual results may differ materially from those expressed or implied in these forward-looking statements as a result of certain known and unknown risks and uncertainties. See “Forward-Looking Statements.”

OVERVIEW

American Coastal Insurance Corporation is a holding company primarily engaged in commercial property and casualty insurance business with investments in the United States. On July 10, 2023, we changed our corporate name from United Insurance Holdings Corp. to American Coastal Insurance Corporation. During the periods presented, we conducted our business principally through our wholly owned insurance subsidiary, American Coastal Insurance Company (AmCoastal). Collectively, we refer to the holding company and all our subsidiaries, including non-insurance subsidiaries, as “ACIC,” which is the preferred brand identification for our Company.

Our Company’s revenue is generated from writing insurance in Florida. Our target market in such areas consists of states where the perceived threat of natural catastrophe has caused large national insurance carriers to reduce their concentration of policies. We believe an opportunity exists for ACIC to write profitable business in such areas. On February 27, 2023, our former insurance subsidiary that wrote personal residential business in six states, United Property & Casualty Insurance Company (UPC) was placed into receivership with the Florida Department of Financial Services (the "DFS"), which divested our ownership of UPC. The events leading to receivership and results of this subsidiary, now included within discontinued operations, can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

On May 9, 2024, we entered into a Stock Purchase Agreement (the "Sale Agreement") with Forza Insurance Holdings, LLC (Forza) in which ACIC agreed to sell and Forza agreed to acquire 100% of the issued and outstanding stock of IIC. Forza’s application to acquire IIC was approved by the New York Department of Financial Services ("NYDFS") on February 13, 2025, and the sale closed on April 1, 2025. The Company received cash proceeds totaling $25,679,000 from the sale resulting in a loss on disposal of $247,000, net of tax impacts. The Company also recognized a $1,348,000 loss, net of tax impacts, on IIC's fixed maturity portfolio, which was included in accumulated other comprehensive loss on the Company's Consolidated Balance Sheets prior to the sale. As a result, IIC results of operations and assets and liabilities are captured within discontinued operations and can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

We have historically grown our business through strong organic growth, complemented by strategic acquisitions and partnerships, including our acquisitions of AmCo Holding Company, LLC (AmCo) and its subsidiaries, including AmCoastal, in April 2017.

Our policies in-force increased by 5.20% from 4,099 policies in-force at December 31, 2024, to 4,311 policies in-force at December 31, 2025.

Our business is subject to the impact of weather-related catastrophes on our loss and loss adjustment expenses (LAE). During the year ended December 31, 2025, no named storms made landfall in our geographic footprint. During the years ended December 31, 2024 and 2023, five and two named storms, respectively, made landfall in our geographic footprint, resulting in retained pre-tax catastrophe losses of $25,442,000 and $729,000 respectively.

For the years ended December 31, 2025 and 2024, we have consolidated our Operating and Underwriting Expenses and General and Administrative Expenses lines within our Consolidated Statements of Comprehensive Income into the General and Administrative Expenses line. This was done in an effort to align more closely with our peer group for comparability. Accordingly, we have recast our Consolidated Statements of Comprehensive Income for the year ended December 31, 2023 to align with this format. We have also added a new note to our consolidated financial statements, Note 3, Disaggregation of Relevant Expense Captions, to provide the users of our financial statements with enhanced insight into this expense line.

AMERICAN COASTAL INSURANCE CORPORATION

The following discussion highlights significant factors influencing the consolidated financial position and results of operations of ACIC. In evaluating our results of operations, we use premiums written and earned, policies in-force and new and renewal policies by geographic concentration. We also consider the impact of catastrophe losses and prior year development on our loss ratios, expense ratios and combined ratios. In monitoring our investments, we use credit quality, investment income, cash flows, realized gains and losses, unrealized gains and losses, asset diversification and portfolio duration. To evaluate our financial condition, we consider our liquidity, financial strength, ratings, book value per share and return on equity.

Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in “Definitions of Non-GAAP Measures”, below.

31

AMERICAN COASTAL INSURANCE CORPORATION

DEFINITIONS OF NON-GAAP MEASURES

We believe that investors’ understanding of ACIC’s performance is enhanced by our disclosure of the following non-GAAP measures. Our methods for calculating these measures may differ from those used by other companies and therefore comparability may be limited.

Combined ratio excluding the effects of current year catastrophe losses and prior year reserve development (underlying combined ratio) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year development from the combined ratio. We believe that this ratio is useful to investors, and it is used by management to highlight the trends in our business that may be obscured by current year catastrophe losses and prior year development. Current year catastrophe losses cause our loss trends to vary significantly between periods as a result of their frequency of occurrence and magnitude, and can have a significant impact on the combined ratio. Prior year development is caused by unexpected loss development on historical reserves. We believe it is useful for investors to evaluate these components separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is the combined ratio. The underlying combined ratio should not be considered as a substitute for the combined ratio and does not reflect the overall profitability of our business.

Net loss and LAE excluding the effects of current year catastrophe losses and prior year reserve development (underlying loss and LAE) is a non-GAAP measure that is computed by subtracting the effect of current year catastrophe losses and prior year reserve development from net loss and LAE. We use underlying loss and LAE figures to analyze our loss trends that may be impacted by current year catastrophe losses and prior year development on our reserves. As discussed previously, these two items can have a significant impact on our loss trends in a given period. We believe it is useful for investors to evaluate these components both separately and in the aggregate when reviewing our performance. The most directly comparable GAAP measure is net loss and LAE. The underlying loss and LAE measure should not be considered a substitute for net loss and LAE and does not reflect the overall profitability of our business.

RESULTS OF OPERATIONS

Consolidated Results

Net income for the year ended December 31, 2025 increased by $31,119,000 to $106,837,000, compared to net income of $75,718,000 for the year ended December 31, 2024. Drivers of net income for 2025 include increased gross premiums earned and decreased ceded premiums earned, driving an overall increase in revenues. In addition, we saw decreased losses and LAE, partially offset by increased policy acquisition costs. During 2024, the Company's net loss attributable to discontinued operations was $601,000, compared to net income of $42,000 during 2025.

Revenues

Our gross written premiums decreased by $35,283,000, or 5.4%, to $612,522,000 for the year ended December 31, 2025, from $647,805,000 for the year ended December 31, 2024. Gross premium earned increased $9,652,000, or 1.5%, to $648,260,000 for the year ended December 31, 2025 from $638,608,000 for the same period in 2024. Ceded premiums earned decreased $23,210,000, or 6.4%, to $341,408,000 for the year ended December 31, 2025, from $364,618,000 for the same period in 2024. The breakdown of the year-over-year change in these premiums and new and renewal policies are shown in the tables below. More detail regarding our ceded premiums can be seen in our analysis of financial condition below.

($ in thousands)	Year Ended December 31,
	2025				2024				Change

	Year Ended December 31,
	2025				2024				Change
New and Renewal Policies		4,363				4,167				196

Ceded premiums earned decreased by $23,210,000, or 6.4%, to $341,408,000 for the year ended December 31, 2025, from $364,618,000 for 2024. The increase is primarily driven by a $51,621,000 decrease in ceded premiums earned from our quota share agreements. This decrease is attributed to the change in AmCoastal’s quota share reinsurance coverage during 2024 and 2025. We had quota share coverage in place at 40% for the first half of 2024, decreasing to 20% effective June 1, 2024. Effective June 1, 2025, this coverage was decreased further to 15%. This decrease was partially offset by a $28,010,000 increase in our catastrophe reinsurance coverage, driven by additional coverage purchased due to exposure growth and the decreased quota share cession rate.

Net investment income increased by $1,411,000, or 6.8%, to $22,206,000 for the year ended December 31, 2025, from $20,795,000 for 2024, driven by increased interest income due to a substantial increase in holdings and higher overall yield on our 2025 portfolio than our 2024 portfolio..

Net realized investment losses and net unrealized gains (losses) on equity securities increased by $4,509,000, or 240.9%, to a net gain of $6,381,000 for the year ended December 31, 2025, from a net gain of $1,872,000 for the year ended December 31, 2024, driven by increased unrealized gains on our equity securities as market conditions were favorable and our holdings increased 40.4% year-over-year.

Expenses

Expenses for the year ended December 31, 2025 decreased $1,899,000, or 1.0%, to $195,162,000, from $197,061,000 for 2024. The decrease in expenses was primarily due to a decrease in loss and LAE as a result of Hurricane Milton making landfall in 2024, which caused a large increase in catastrophe losses due to the $20,500,000 retention incurred from the storm. This was offset by an

increase in policy acquisition costs, the details of which can be seen below. The calculations of our combined loss ratios and underlying loss ratios are shown below.

Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in the “Definitions of Non-GAAP Measures” section, above.

The calculations of the Company’s expense ratios are shown below.

Loss and LAE decreased by $23,279,000, or 33.6%, to $46,040,000 for the year ended December 31, 2025, from $69,319,000 for the year ended December 31, 2024. Loss and LAE expense as a percentage of net earned premiums decreased 10.3 points to 15.0% for the year ended December 31, 2025, compared to 25.3% for the year ended December 31, 2024. In addition, during the year ended December 31, 2025, prior year reserve favorable development was higher on both catastrophe and non-catastrophe losses and catastrophe losses were lower. Excluding catastrophe losses and reserve development, our gross underlying loss and LAE ratio for the year ended December 31, 2025 would have been 7.8%, an increase of 0.4 points from 7.4% during the year ended December 31, 2024.

Policy acquisition costs increased by $26,854,000, or 37.8%, to $97,844,000 for the year ended December 31, 2025, from $70,990,000 for the year ended December 31, 2024. The primary driver of the increase was a decrease in ceding commission income of $17,161,000, driven by the changes in the terms of our quota share reinsurance agreement described above. In addition, external management fees increased $9,807,000, as a result of a one percent increase in the management fee and profit share accrual pursuant to the renewal terms for the contract with AmRisc, LLC, effective June 1, 2024.

General and administrative expenses decreased by $4,293,000, or 9.6%, to $40,463,000 for the year ended December 31, 2025, from $44,756,000 for the year ended December 31, 2024, driven largely by a decrease in external spending for professional and consulting services, audit fees and legal fees totaling $2,471,000 as well as decreased depreciation and amortization of $1,256,000.

We experienced favorable reserve development in the current year and its historical impact on our net loss and net underlying loss ratios is outlined in the following table.

ANALYSIS OF FINANCIAL CONDITION

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our accompanying consolidated financial statements and related notes in Part II, Item 8 in this Form 10-K.

Investments

The primary goals of our investment strategy are to preserve capital, maximize after-tax investment income, maintain liquidity and minimize risk. To accomplish our goals, we purchase debt securities in sectors that represent the most attractive relative value, and we maintain a moderate equity exposure. Limiting equity exposure manages risks and helps to preserve capital for two reasons: first, bond market returns are less volatile than stock market returns, and second, should the bond issuer enter bankruptcy liquidation, bondholders generally have a higher priority than equity holders in a bankruptcy proceeding.

We must comply with applicable state insurance regulations that prescribe the type, quality and concentrations of investments our insurance subsidiary can make; therefore, our current investment policy limits investment in non-investment-grade fixed maturities and limits total investment amounts in preferred stock, common stock and mortgage notes receivable. We do not invest in derivative securities, however, we do hold warrants as a result of our surplus note investment. Please see Note 5 for more information.

As of December 31, 2025, one outside asset management company, which has authority and discretion to buy and sell securities for us, manages our investments subject to (i) the guidelines established by our Board of Directors and (ii) the direction of management. Prior to August 2025, we engaged two outside asset management companies. The Investment Committee of our Board of Directors reviews and approves our investment policy on a regular basis.

Our cash and investment portfolios totaled $647,744,000 at December 31, 2025, compared to $540,811,000 at December 31, 2024.

The following table summarizes our investments, by type:

	December 31, 2025									December 31, 2024

Total cash, cash equivalents, restricted cash and investments	$	647,744				100.0		%		$	540,811				100.0		%

We classify all of our investments as available-for-sale. Our investments as of December 31, 2025 and 2024 consisted mainly of U.S. government and agency securities, securities of investment-grade corporate issuers, mortgage-backed securities, and states, municipalities and political subdivisions. Our equity holdings as of December 31, 2025 consisted of mutual funds and common stock. We held no equities as of December 31, 2024. Most of the corporate bonds we hold reflected a similar diversification. At December 31,

35

AMERICAN COASTAL INSURANCE CORPORATION

2025, approximately 82.6% of our fixed maturities were U.S. Treasuries or corporate bonds rated “A” or better, and 17.4% were corporate bonds rated “BBB” or “BB”.

Reinsurance

We follow the industry practice of reinsuring a portion of our risks. Reinsurance involves transferring, or "ceding", all or a portion of the risk exposure on policies we write to another insurer, known as a reinsurer. To the extent that our reinsurers are unable to meet the obligations they assume under our reinsurance agreements, we remain primarily liable for the entire insured loss under the policies we write.

Our catastrophe reinsurance coverage consists of three separate placements:

1.AmCoastal’s core catastrophe reinsurance program, including catastrophe bonds (effective April 2024 and December 2024), in effect June 1 through May 31, annually, which includes excess of loss and quota share treaties providing coverage for catastrophe losses from named or numbered windstorms;

2.AmCoastal’s all other perils catastrophe excess of loss agreement in effect January 1 through December 31, annually, which provides protection from catastrophe loss events other than named or numbered windstorms and earthquakes; and

3.AmCoastal's catastrophe aggregate excess of loss coverage, in effect Jan 1 through December 31, annually, which provides protection from all catastrophe loss events, including named windstorms, severe convective storms and winter storm events.

This reinsurance protection is an essential part of our catastrophe risk management strategy. It is intended to provide our stockholders with an acceptable return on the risks assumed by our insurance entity, and to reduce the variability of earnings, while providing surplus protection. Although reinsurance agreements contractually obligate our reinsurers to reimburse us for the agreed-upon portion of our gross paid losses, they do not discharge our primary liability. In the event one or more of our reinsurers fail to fulfill their obligation, the surplus of our statutory entity may decline, and we may not be able to fulfill our obligation to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. Additionally, we face the risk that actual losses incurred from one or more catastrophic events may be above the modeled expected loss resulting in losses exceeding our reinsurance coverage, which may result in a decline in surplus, and as a result we may not be able to fulfill our obligations to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. The details of our programs and the likelihood of a catastrophic event exceeding these two coverages are outlined below.

AmCoastal’s core catastrophe reinsurance program provides occurrence-based coverage up to an exhaustion point of approximately $1,330,000,000 for a first occurrence and $1,676,000,000 in the aggregate. Under this program, the Company's GAAP retention on a first event is $29,750,000 ($14,000,000 retained by AmCoastal under statutory accounting principles (STAT retained), $15,750,000 (retained separately by the Company's captive)). The Company has purchased second and third event retrocession coverage, reducing its second event GAAP retention to $18,500,000 ($14,000,000 STAT retained by AmCoastal, $4,500,000 retained separately by the Company's captive) and third event GAAP retention to $3,750,000, based on three $100,000,000 loss events. AmCoastal’s program provides sufficient coverage for approximately a 1-in-203-year return period, indicating that the probability of a single occurrence exceeding protection purchased is roughly 0.5% estimated by blending the AIR 10, AIR 11.5, RMS 22 and RMS 23 catastrophe models using long-term catalogs including demand surge and based on total insured value at September 30, 2025 of $69 billion. AmCoastal’s program also provides sufficient coverage for a 1-in-100-year event followed by a 1-in-50-year event in the same treaty year, the probability of which is less than 0.1%. While we believe these catastrophe models are very good tools and their output provides reasonable proxies for the probability of exhausting our reinsurance protections, they are imperfect, so actual results could vary dramatically from those expected.

AmCoastal’s all other perils catastrophe excess of loss agreement provides protection from catastrophe loss events other than named windstorms and earthquakes up to $88,200,000 for a first and second event, totaling $176,400,000 in the aggregate. This agreement provides sufficient coverage for approximately a 1-in-450-year return period, indicating that the probability of a single occurrence exceeding protection purchased is no more than 0.2%.

In addition to the programs described above, AmCoastal purchased a new catastrophe aggregate excess of loss coverage (the “CAT Agg” agreement) to mitigate our catastrophe frequency risk. This agreement provides coverage for in-force, new and renewal business.

36

AMERICAN COASTAL INSURANCE CORPORATION

Effective January 1, 2025, the new CAT Agg agreement provides $40,000,000 of aggregate limit (with a $20,000,000 per occurrence cap) in excess of zero after the $40,000,000 annual aggregate deductible has been met. The CAT Agg agreement limits our losses from all catastrophe loss events, including named windstorms, severe convective storms and winter storm events for the full year ending December 31, 2025.

Effective December 15, 2023, we agreed to commute a private reinsurer’s share of core catastrophe reinsurance coverage and replace this gap in coverage with new coverage provided by one of our other private reinsurers. This transaction resulted in a reduction in expense of approximately $6,300,000 and $15,700,000 during the three and six months ended June 30, 2024, respectively.

Where we think prudent, particularly where premium rates are high relative to the risk, we retain risk whereby AmCoastal purchases reinsurance from Shoreline Re, our captive reinsurance entity. Shoreline Re participates on AmCoastal's all other perils catastrophe excess of loss agreement and AmCoastal's excess per risk agreement. In addition, Shoreline Re participates in a 45% quota share agreement with AmCoastal, which provides coverage for all catastrophe perils as well as attritional losses incurred.

The table below outlines the participation of Shoreline Re for each program, including premium received and capital at risk.

Treaty		Effective Dates		Premium Collected / Cession Rate				Capital at Risk (1)
Quota Share Agreement		06/01/2025 - 05/31/2026		45% (2)				$	33,346,000		(3)

Quota Share Agreement (5)		06/01/2024 - 05/31/2026		30% (2)				$	4,200,000		(6)

(1) Capital at risk is calculated by taking the aggregate losses Shoreline Re is subject to under the contract, less net premiums earned under the contract.

(2) This treaty provides or provided coverage for all catastrophe perils and attritional losses incurred. For all catastrophe perils, the quota share agreement provides or provided ground-up protection, effectively reducing our retention for catastrophe losses.

(3) Net premiums earned based on estimated subject premiums at June 1, 2025.

(4) This treaty was amended on June 1, 2025 to include reinstatement, resulting in additional premium and aggregate losses.

(5) This treaty was commuted on June 1, 2025 with no impact on our consolidated results.

(6) Net premiums earned based on estimated subject premiums at June 1, 2024.

The table below outlines our quota share agreements in effect for the years ended December 31, 2025 and 2024.

Reinsurer		Companies in Scope		Effective Dates		Cession Rate		States in Scope

External third-party		AmCoastal		06/01/2023 - 05/31/2024		40% (1)		Florida

(1) This treaty provides or provided coverage for all catastrophe perils and attritional losses incurred. For all catastrophe perils, the quota share agreement provides or provided ground-up protection, effectively reducing our retention for catastrophe losses.

(2) The cession rate of this treaty was reduced from 20% to 15% effective June 1, 2025 to May 31 , 2026.

Reinsurance costs as a percentage of gross earned premium during the years ended December 31, 2025 and 2024 were as follows:

See Note 10 in our Notes to Consolidated Financial Statements for additional information regarding our reinsurance program.

Unpaid Losses and Loss Adjustments

We generally use the term “loss(es)” to collectively refer to both loss and LAE. We establish reserves for both reported and unreported unpaid losses that have occurred at or before the balance sheet date for amounts we estimate we will be required to pay in the future, including provisions for claims that have been reported but are unpaid at the balance sheet date and for obligations on claims that have been incurred but not reported at the balance sheet date. Our policy is to establish these loss reserves after considering all information known to us at each reporting period. At any given point in time, our loss reserve represents our best estimate of the ultimate settlement and administration costs of our insured claims incurred and unpaid.

Unpaid losses and LAE totaled $165,701,000 and $322,087,000 as of December 31, 2025 and 2024, respectively.

Since the process of estimating loss reserves requires significant judgment due to a number of variables, such as fluctuations in inflation, judicial decisions, legislative changes and changes in claims handling procedures, our ultimate liability will likely differ from

38

AMERICAN COASTAL INSURANCE CORPORATION

these estimates. We revise our reserve for unpaid losses as additional information becomes available, and reflect adjustments, if any, in our earnings in the periods in which we determine the adjustments are necessary.

See Note 11 in our Notes to Consolidated Financial Statements for additional information regarding our losses and LAE.

Discontinued Operations

On February 10, 2023, we announced that a solvent run-off for UPC was unlikely and on February 27, 2023, UPC was placed into receivership with the DFS, which divested our ownership of UPC. As a result, UPC, as well as the activities related directly to supporting the business conducted by UPC, qualify as a discontinued operation. For more information regarding the results of our discontinued operations, see Note 4 in our Notes to Consolidated Financial Statements.

In addition, On May 9, 2024, we entered into a Stock Purchase Agreement (the "Sale Agreement") with Forza Insurance Holdings, LLC (Forza) in which ACIC agreed to sell and Forza agreed to acquire 100% of the issued and outstanding stock of IIC. Forza’s application to acquire IIC was approved by the New York Department of Financial Services ("NYDFS") on February 13, 2025, and the sale closed on April 1, 2025. The Company received cash proceeds totaling $25,679,000 from the sale resulting in a loss on disposal of $247,000, net of tax impacts. The Company also recognized a $1,348,000 loss, net of tax impacts, on IIC's fixed maturity portfolio, which was included in accumulated other comprehensive loss on the Company's Consolidated Balance Sheets prior to the sale. As a result, IIC results of operations and assets and liabilities are captured within discontinued operations and can be seen in Note 4 of the Notes to Consolidated Financial Statements below.

LIQUIDITY AND CAPITAL RESOURCES

We generate cash through premium collections, reinsurance recoveries, investment income, the sale or maturity of invested assets, the issuance of debt and the issuance of additional shares of our stock. We use our cash to pay reinsurance premiums, claims and related costs, policy acquisition costs, salaries and employee benefits, other expenses and stockholder dividends, acquire subsidiaries and pay associated costs, as well as to repay debt and purchase investments.

As a holding company, we do not conduct any business operations of our own and, as a result, we rely on cash dividends or intercompany loans from our management subsidiaries to pay our general and administrative expenses. Insurance regulatory authorities heavily regulate our insurance subsidiary, including restricting any dividends paid by our insurance subsidiary and requiring approval of any management fees our insurance subsidiary pay to our management subsidiaries for services rendered; however, nothing restricts our non-insurance company subsidiary from paying us dividends other than state corporate laws regarding solvency. Our management subsidiary pays us dividends primarily using cash from the collection of management fees from our insurance subsidiary, pursuant to the management agreements in effect between those entities. In accordance with state laws, our insurance subsidiary may pay dividends or make distributions out of that part of their statutory surplus derived from their net operating profit and their net realized capital gains. The risk-based capital (RBC) guidelines published by the National Association of Insurance Commissioners (NAIC) may further restrict our insurance subsidiary’s ability to pay dividends or make distributions if the amount of the intended dividend or distribution would cause their respective surplus as it regards policyholders to fall below minimum RBC guidelines. See Note 16 in our Notes to Consolidated Financial Statements and Part II, Item 5 for additional information.

During the year ended December 31, 2025, the Company made capital contributions of $8,269,000 to its reinsurance subsidiary, Shoreline Re. In addition, the Company made a $15,000,000 contribution to form a new excess and surplus insurance entity, that has not yet begun operations. We may make future contributions of capital to our insurance subsidiary as circumstances require. During the year ended December 31, 2024, the Company made capital contributions of $1,265,000 to its reinsurance subsidiary, Shoreline Re. During the year ended December 31, 2023, we made no capital contributions to our subsidiaries.

During the years ended December 31, 2025 and 2024, the Company received dividends of $23,000,000 and $14,300,000, respectively from our insurance subsidiary, AmCoastal.

39

AMERICAN COASTAL INSURANCE CORPORATION

In September 2023, the Company entered into an equity distribution agreement (the “Agreement”) with Raymond James & Associates, Inc., as agent (the “Agent”), of up to 8,000,000 shares of the Company’s common stock, par value $0.0001 per share (the “Shares”). Sales of the Shares under the Agreement will be made in sales deemed to be “at the market offerings”. The Agent is not required to sell any specific amount of Shares but has agreed to act as the Company’s sales agent for a commission equal to 3.0% of the gross proceeds from the sales of the Shares. As of December 31, 2025, 4,373,000 shares had been sold under the Agreement resulting in commissions paid of approximately $1,181,000 and net proceeds of approximately $38,190,000. The Agreement will terminate upon the issuance and sale of all Shares subject to the Agreement, or the Agreement may be suspended or discontinued at any time.

On December 13, 2017, we issued $150,000,000 of senior notes (Senior Notes) that will mature on December 15, 2027 and bear interest at a rate equal to 6.25% per annum payable semi-annually on each June 15 and December 15, commencing June 15, 2018. The Senior Notes are senior unsecured obligations of the Company. We may redeem the Senior Notes at our option, at any time and from time to time in whole or in part, at a redemption price equal to the greater of (i) 100% of the principal amount of the Senior Notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the date of redemption to the date that is three months prior to maturity. On and after that date, we may redeem the Senior Notes at par. On December 8, 2022, the Kroll Bond Rating Agency, LLC announced a downgrade of our issuer and debt ratings from BBB- to BB+. As a result, pursuant to our agreement, the interest rate of our Senior Notes increased from 6.25% to 7.25% effective June 15, 2023. On July 21, 2025, the Kroll Bond Rating Agency, LLC announced an upgrade of the Company's issuer and debt ratings from BB+ to BBB-. As a result, pursuant to the Company's indenture, the interest rate of its Senior Notes decreased from 7.25% to 6.25% effective December 16, 2025.

As a result of claim activity from the current and prior years, we have an obligation related to the unpaid policyholder losses and unpaid LAE associated with the settling of these claims. As of December 31, 2025, our total obligation related to these claim payments was $165,701,000, of which we estimate $83,995,000 to be short-term in nature (due in less than twelve months), based upon our cumulative claims paid historically. While we believe that historical performance of loss payment patterns is a reasonable source for projecting future claim payments, there is inherent uncertainty in these estimated projected settlements, and as a result these estimates will differ, perhaps significantly, from actual future payments.

In addition to our unpaid loss and LAE, as of December 31, 2025, we have outstanding debt obligations related to our notes payable totaling $150,000,000. This is exclusive of interest costs, which we estimate will total $21,750,000 over the life of the debt, based on the current fixed interest rates of these notes. Our short-term obligation related to these notes payable total $10,875,000 in estimated interest payments and no principal payments. For more information regarding these outstanding notes, please see Note 12 in our Notes to Consolidated Financial Statements.

In connection with entering into contracts with our outside vendors, we have minimum obligations due to our vendors over the life of the contracts. Our main vendor obligations are related to underwriting and other administrative tools. Our total obligation related to these two categories of obligations are $1,937,000, and $250,000, respectively. Of these obligations, $627,000, and $250,000, respectively, are short-term in nature.

Cash Flows for the Year Ended December 31, (in thousands)

	Year Ended December 31,

Net cash provided by (used in) financing activities	$	(1,081	)		$	(13,840	)		$	26,769

Operating Activities

The principal cash inflows from our operating activities come from premium collections, reinsurance recoveries and investment income. The principal cash outflows from our operating activities are the result of claims and related costs, reinsurance premiums, policy acquisition costs and salaries and employee benefits. A primary liquidity concern with respect to these cash flows is the risk of large magnitude catastrophe events.

40

AMERICAN COASTAL INSURANCE CORPORATION

During the year ended December 31, 2025, we experienced cash inflows of $71,025,000 compared to inflows of $243,509,000 during the year ended December 31, 2024. This change was driven by changes in our operating assets and liabilities of $215,474,000, partially offset by an increase in net income, net of adjustments to reconcile net income to cash of $42,990,000. The change in our operating assets and liabilities is attributable primarily to settlements triggered by Hurricane Milton making landfall in the fourth quarter of 2024 with no similar activity occurring in 2025 as well as a large shift in our change in reinsurance payable as our payment schedule normalized in 2024, resulting in similar payments occurring for the same period in 2025.

Investing Activities

The principal cash inflows from our investing activities come from repayments of principal, proceeds from maturities and sales of investments. We closely monitor and manage these risks through our comprehensive investment risk management process. The principal cash outflows relate to purchases of investments. Additional cash outflows relate to the purchase of fixed assets. The primary liquidity concerns with respect to these cash flows are the risk of default by debtors and market disruption. During the year ended December 31, 2025, cash provided by investing activities increased $179,831,000, driven by the purchases of fixed maturities in the prior year.

Financing Activities

The principal cash inflows from our financing activities come from issuances of debt and other securities. The principal cash outflows come from repayments of debt and payments of dividends. The primary liquidity concern with respect to these cash flows is market disruption in the cost and availability of credit. We believe our current capital resources, together with cash provided from our operations, are sufficient to meet currently anticipated working capital requirements. During the year ended December 31, 2025, cash used in financing activities decreased by $12,759,000 to cash used of $1,081,000 from cash used of $13,840,000. This was due primarily to $24,102,000 in dividends declared during 2024 and a decrease in proceeds from the issuance of common stock of $10,847,000 year-over-year.

RECENT ACCOUNTING STANDARDS

Please refer to Note 2(v) in our Notes to Consolidated Financial Statements for a discussion of recent accounting standards that may affect us.

APPLICATION OF CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with GAAP requires management to adopt accounting policies and make estimates and assumptions that affect amounts reported in the consolidated financial statements. The most critical estimates include those used in determining:

•reserves for unpaid losses,

•fair value of investments, and

•goodwill.

In making these determinations, management makes subjective and complex judgments that frequently require estimates about matters that are inherently uncertain. Many of these policies, estimates and related judgments are common in the insurance industry. It is reasonably likely that changes in these estimates could occur from time to time and result in a material impact on our consolidated financial statements.

In addition, the preparation of our financial statements in accordance with GAAP prescribes when we may reserve for particular risks, including litigation exposures. Accordingly, our results for a given reporting period could be significantly affected if and when we establish a reserve for a major contingency. Therefore, the results we report in certain accounting periods may appear to be volatile and past results may not be indicative of results in future periods.

Reserves for Unpaid Losses and LAE

Reserves for unpaid losses and LAE represent the most significant accounting estimate inherent in the preparation of our financial statements. These reserves represent management’s best estimate of the amount we will ultimately pay for losses, and we base the

41

AMERICAN COASTAL INSURANCE CORPORATION

amount upon the application of various actuarial reserve estimation techniques as well as other material facts and circumstances known at the balance sheet date.

As discussed in Note 11 in our Notes to Consolidated Financial Statements, we estimate our ultimate losses by using multiple actuarial methods to determine an actuarial estimate within a relevant range of indications that we calculate using generally accepted actuarial techniques. Our selection of the actuarial estimate is influenced by the analysis of our historical loss and claims experience since inception. For each accident year, we estimate the ultimate incurred losses for both reported and unreported claims. In establishing this estimate, we reviewed the results of various actuarial methods discussed in Note 11 in our Notes to Consolidated Financial Statements.

Fair Value of Investments

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. We are responsible for the determination of fair value of financial assets and the supporting assumptions and methodologies. We use quoted prices from active markets and an independent third-party valuation service to assist us in determining fair value. We obtain only one single quote or price for each financial instrument.

As discussed in Note 5 in our Notes to Consolidated Financial Statements, we value our investments at fair value using quoted prices from active markets, to the extent available. For securities for which quoted prices in active markets are unavailable, we use observable inputs such as quoted prices in inactive markets, quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs. We also have investments in limited partnerships that require us to use the net asset value per share method of valuation to determine fair value.

See “Item 7A. Quantitative and Qualitative Disclosures About Market Risk” for more information regarding the sensitivity of our fixed maturity portfolio to changes in interest rates.

Measurement of Goodwill and Related Impairment

Goodwill is the excess of cost over the estimated fair value of net assets acquired. Goodwill is not amortized but is tested for impairment at least annually or more frequently if events or circumstances, such as adverse changes in the business climate, indicate that there may be justification for conducting an interim test. We test goodwill for impairment by performing a quantitative assessment. Goodwill is impaired when it is determined that the carrying value of a reporting segment is in excess of the fair value of that reporting segment. The valuation methodologies utilized are subject to key judgments and assumptions that are sensitive to change. Estimates of fair value are inherently uncertain and represent only management’s reasonable expectation regarding future developments.

Please refer to Note 2(k) and Note 9 in our Notes to Consolidated Financial Statements for further information regarding our measurement of Goodwill and Related Impairment.

RELATED PARTY TRANSACTIONS

There were no related party transactions for the years ended December 31, 2025, 2024 and 2023.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Our investment objective is to preserve capital, maximize after-tax investment income, maintain liquidity and minimize risk. Our current investment policy limits investment in non-investment grade debt securities, and limits total investments in preferred stock, common stock and mortgage notes receivables. We also comply with applicable laws and regulations that further restrict the type, quality and concentration of our investments. In general, these laws and regulations permit investments, within specified limits and subject to certain qualifications, in federal, state and municipal obligations, corporate bonds, and preferred and common equity securities.

Our investment policy was established by the Investment Committee of our Board of Directors and is reviewed regularly. Pursuant to this investment policy, our fixed-maturity portfolio is classified as available for sale and we report any unrealized gains or losses, net of deferred income taxes, as a component of other comprehensive income (loss) within our stockholders’ equity (deficit). We do not hold any securities that are classified as held to maturity and we do not hold any securities for trading or speculation. We do not utilize

42

AMERICAN COASTAL INSURANCE CORPORATION

any swaps, options, futures or forward contracts to hedge or enhance our investment portfolio. The unrealized gains or losses related to our equity securities are recorded on the income statement per the guidance in ASU 2016-01.

INTEREST RATE RISK

Fixed-income securities are sensitive to potential losses resulting from unfavorable changes in interest rates. We manage the risk by analyzing anticipated movements in interest rates and considering our future capital and liquidity requirements.

The following table illustrates the impact of hypothetical changes in interest rates on the fair value of our fixed-income securities at December 31, 2025 and 2024:

Hypothetical Change in Interest Rates		Estimated Fair Value				Change in Estimated Fair Value				Percentage Increase (Decrease) in Estimated Fair Value
2025
300 basis point increase		$	234,734			$	(18,418	)			(7.3	)%
200 basis point increase			240,578				(12,574	)			(5.0	)
100 basis point increase			246,718				(6,434	)			(2.5	)
Fair value			253,152				—				—
100 basis point decrease			259,882				6,730				2.7
200 basis point decrease			266,907				13,755				5.4
300 basis point decrease			274,212				21,060				8.3	%
2024
300 basis point increase		$	262,720			$	(18,281	)			(6.5	)%
200 basis point increase			268,811				(12,190	)			(4.3	)
100 basis point increase			274,904				(6,097	)			(2.2	)
Fair value			281,001				—				—
100 basis point decrease			287,101				6,100				2.2
200 basis point decrease			293,204				12,203				4.3
300 basis point decrease			299,310				18,309				6.5	%

Our calculations of the potential effects of hypothetical interest rate changes are based on several assumptions, including maintenance of the existing composition of fixed-income investments, and should not be considered indicative of future results. Based on our analysis, both a 200 and 300-basis point decrease or increase in interest rates from the December 31, 2025 rates would have a material impact on our results of operations and cash flows in the event divesting of these holdings was necessary. However, we do not anticipate the need to sell securities in an unrealized loss position as of December 31, 2025.

CREDIT RISK

Credit risk can expose us to potential losses arising principally from adverse changes in the financial condition of the issuer of our fixed-maturity securities. We mitigate this risk by generally investing in investment grade securities and by diversifying our investment portfolio to avoid concentrations in any single issuer or market sector.

The following table presents the composition of our fixed-income security portfolio by rating at December 31, 2025 and 2024:

Comparable Rating		Amortized Cost				% of Total Amortized Cost				Fair Value				% of Total Fair Value
2025
AAA		$	46,181				17.7	%		$	42,962				17.0	%

Total		$	295,547				100.0	%		$	281,001				100.0	%

In addition, we are exposed to credit risk through our reinsurance program. Reinsurance contracts do not relieve us from our obligations to policyholders. Failure of reinsurers to honor their obligations could result in losses to us. We evaluate the financial condition of our reinsurers and monitor concentrations of credit risk to minimize our exposure to significant losses from reinsurer insolvencies.

We also are exposed to credit risk through our outstanding premiums receivable balances. We evaluate the age of our premium receivables to minimize our exposure to significant losses due to nonpayment.

After our evaluation of all credit risks described above, if we feel it is necessary, we record a credit loss allowance to address these credit risks. For more information regarding our credit loss allowance, please refer to Note 14.

EQUITY PRICE RISK

Our equity investment portfolio at December 31, 2025 consisted of common stocks. We may incur potential losses due to adverse changes in equity security prices. We manage this risk primarily through industry and issuer diversification and asset allocation techniques.

During 2025, we increased our equity portfolio from 10.8% of our total investments (excluding cash, restricted cash and cash equivalents) at December 31, 2024 to 17.4% of our total investments (excluding cash, restricted cash and cash equivalents) at December 31, 2025.

Item 8. Financial Statements and Supplementary Data

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of American Coastal Insurance Corporation

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American Coastal Insurance Corporation and subsidiaries (the "Company") as of December 31, 2025 and 2024, the related consolidated statements of comprehensive income, stockholders' equity (deficit), and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). In our opinion, the 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 three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

We have also 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 March 9, 2026, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's 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 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 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 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 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 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 financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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.

Liability for Unpaid Losses and Loss Adjustment Expenses — Refer to Notes 2, 11 and 13 to the Financial Statements

Critical Audit Matter Description

As a provider of property and casualty insurance, the Company establishes reserves for both reported and unreported unpaid losses that have occurred at or before the balance sheet date for amounts estimated which they will be required to pay in the future, including provisions for claims that have been reported but are unpaid at the balance sheet date and for obligations on claims that have been incurred but not reported at the balance sheet date (herein, “loss reserves”). Due to the nature and unpredictability in both the severity and frequency of these events and their related claims, the Company uses a significant amount of judgment in estimating the loss reserves, including analyzing historical and industry loss data, claims frequency and severity, claims processing procedures, legislative enactments, judicial decisions and legal developments in imposition of damages, and general economic conditions, including inflation.

46

AMERICAN COASTAL INSURANCE CORPORATION

Additionally, the Company engages independent actuarial specialists in order to assist management in establishing appropriate loss reserves.

Given the amount of judgment necessary to estimate the projected losses to be incurred by the Company as it relates to both reported and unreported claims, performing audit procedures to evaluate whether the Company’s loss reserves were appropriately recorded as of December 31, 2025, required a high degree of auditor judgment and an increased extent of effort, including the need to involve our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the loss reserves included the following, among others:

•We tested the design, implementation, and operating effectiveness of controls over the liability for unpaid losses and loss adjustment expenses, including those related to the estimation and management’s review of the estimates as well as the selection of underlying assumptions.

•With assistance from our actuarial specialists, we developed an independent expected range of unpaid losses and loss adjustment expense based on historical and industry claim development factors and compared our estimates to management’s estimates and assessed the consistency of management’s approach.

•We evaluated the methods and assumptions used by management to estimate the loss reserves by:

oTesting the underlying data that served as the basis for the actuarial analysis, including historical claims, to test that the inputs to the actuarial estimate were reasonable.

oPerforming inquiry of management to discuss the Company’s ultimate recorded reserve actions and understand any trends that have been observed in the Company’s claims data.

oPerforming a retrospective review, including comparing prior year estimates of expected incurred losses to actual experience during the current year to identify potential bias in the determination of the liability for unpaid losses and loss adjustment expense.

Notes to Consolidated Financial Statements

December 31, 2025

1)ORGANIZATION, CONSOLIDATION AND PRESENTATION

(a)Business

American Coastal Insurance Corporation (referred to in this document as we, our, us, the Company or ACIC) is a property and casualty insurance holding company that sources, writes and services residential commercial property insurance policies using a network of agents and one wholly owned insurance subsidiary, American Coastal Insurance Company (AmCoastal), acquired via merger on April 3, 2017. On July 10, 2023, we changed our corporate name from United Insurance Holdings Corp. to American Coastal Insurance Corporation. The Company also previously wrote insurance through Interboro Insurance Company (IIC); however, on April 1, 2025, the Company completed the sale of IIC. The details of this transaction are described below.

The Company's other subsidiaries include Skyway Underwriters, LLC, a managing general agent that provides policy and claims administration, underwriting, technological and distribution services to the Company's insurance company; AmCo Holding Company, LLC (AmCo), which is a holding company subsidiary that consolidates its respective insurance company; BlueLine Cayman Holdings (BlueLine), which reinsures portfolios of excess and surplus policies; and Shoreline Re, which provides a portion of the reinsurance protection purchased by the Company's insurance subsidiary where management deems prudent. The Company also has several subsidiaries in run-off including United Insurance Management, L.C. (UIM), a managing general agent; Skyway Claims Services, LLC (SCS), which previously provided claims adjusting services to the Company's insurance companies; Skyway Reinsurance Services, LLC, which previously provided reinsurance brokerage services for the Company's insurance companies; and Skyway Legal Services, LLC (SLS), which previously provided claims litigation services to the Company's insurance companies.

We write commercial residential property insurance in Florida. On February 27, 2023, our former insurance subsidiary that wrote personal residential business in six states, United Property & Casualty Insurance Company (UPC), was placed into receivership with the Florida Department of Financial Services (DFS), which divested our ownership of UPC. The events leading to receivership and results of this subsidiary, now included within discontinued operations, are discussed in Note 4 below.

On May 9, 2024, we entered into a Stock Purchase Agreement (the "Sale Agreement") with Forza Insurance Holdings, LLC (Forza) in which we agreed to sell and Forza agreed to acquire 100% of the issued and outstanding stock of IIC. Forza’s application to acquire IIC was approved by the New York Department of Financial Services (NYDFS) on February 13, 2025 and the sale closed on April 1, 2025. The aggregate purchase price for the shares was equal to IIC's shareholders' equity under U.S. generally accepted accounting principles (GAAP) on the closing date. IIC results of operations and assets and liabilities are captured within discontinued operations and are discussed in Note 4 of the Notes to Consolidated Financial Statements below.

As a result of the Sale Agreement described above, IIC is presented as discontinued operations. The remaining activity captured within continuing operations supports only our commercial residential insurance offerings. Given this fact pattern, we conduct our operations under one operating segment, which consists of our commercial lines business. Further information regarding this segment can be seen in Note 2(j) below.

(b)Consolidation and Presentation

We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles (GAAP). While preparing our consolidated financial statements, we make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, as well as reported amounts of revenues and expenses during the reporting period. Accordingly, actual results could differ from those estimates. Reported amounts that require us to make extensive use of estimates include our reserves for unpaid losses and loss adjustment expenses, investments and goodwill. Except for the captions on our Consolidated Balance Sheets and Consolidated Statements of Comprehensive Income (Loss), we generally use the term loss(es) to collectively refer to both loss and loss adjustment expenses.

We include all our subsidiaries in our consolidated financial statements, eliminating intercompany balances and transactions during consolidation. As described in Note 2, our former subsidiaries, IIC and UPC, and activities related directly to supporting the business conducted by UPC, qualified as discontinued operations.

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

For the years ended December 31, 2025 and 2024, we have consolidated our Operating and Underwriting Expenses and General and Administrative Expenses lines within our Consolidated Statements of Comprehensive Income into the General and Administrative Expenses line. This was done in an effort to align more closely with our peer group for comparability. Accordingly, we have recast our Consolidated Statements of Comprehensive Income for the year ended December 31, 2023 to align with this format. We have also added a new note to our consolidated financial statements, Note 3, Disaggregation of Relevant Expense Captions, to provide the users of our financial statements with enhanced insight into this expense line.

In addition, for the year ended December 31, 2025, we have consolidated our Payments outstanding line within our Consolidated Balance Sheets into the Other Liabilities line. This was done based on the size of our Payments outstanding over the last three years. Accordingly, we have recast our Consolidated Balance Sheets for the year ended December 31, 2024 to align with this format.

2)SIGNIFICANT ACCOUNTING POLICIES

(a)Cash, cash equivalents, and restricted cash

Our cash, cash equivalents, and restricted cash include demand deposits with financial institutions, cash that is held in trust for assumed business, cash held in deposit accounts to satisfy statutory deposit requirements, and short-term, highly liquid instruments with original maturities of three months or less when purchased.

(b)Investments

We currently classify all our investments in fixed maturities and short-term investments as available-for-sale, and report them, our equity securities and limited partnership investments at fair value. Subsequent to our acquisition of available-for-sale securities, we record changes in value through the date of disposition as unrealized holding gains and losses, net of tax effects, and include them as a component of comprehensive income (loss). We include realized gains and losses, which we calculate using the specific-identification method for determining the cost of securities sold, in net loss. We amortize any premium or discount on fixed maturities over the remaining maturity period of the related securities using the effective interest method, and we report the amortization in net investment income. We recognize dividends and interest income when earned. In addition, we hold a commercial mortgage loan classified as held-for-long-term and a surplus note which is classified as held-to-maturity. Both of these investments are carried at amortized cost.

Quarterly, we perform an assessment of our investments to determine if any are impaired as the result of a credit loss. An investment is impaired when the fair value of the investment declines to an amount less than the cost or amortized cost of that investment. For each fixed-income security in an unrealized loss position, if we determine that we intend to sell the security or that it is more likely than not that we will be required to sell the security before recovery of the cost or amortized cost basis for reasons such as liquidity needs, contractual or regulatory requirements, the security’s entire decline in fair value is recorded in earnings.

If our management decides not to sell the fixed-income security and it is more likely than not that we will not be required to sell the fixed-income security before recovery of its amortized cost basis, we evaluate whether the decline in fair value has resulted from credit losses or other factors. This is typically indicated by a change in the rating of the security assigned by a rating agency, and any adverse conditions specifically related to the security or industry, among other factors. If the assessment indicates that a credit loss may exist, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses will be recorded in earnings. Credit loss is limited to the difference between a security's amortized cost basis and its fair value. Any additional impairment not recorded through an allowance for credit losses is recognized in other comprehensive income (loss).

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

A large portion of our investment portfolio consists of fixed maturities, which may be adversely affected by changes in interest rates as a result of governmental monetary policies, domestic and international economic and political conditions and other factors beyond our control. A rise in interest rates would decrease the net unrealized holding gains of our investment portfolio, offset by our ability to earn higher rates of return on funds reinvested. Conversely, a decline in interest rates would increase the net unrealized holding gains of our investment portfolio, offset by lower rates of return on funds reinvested.

(c)Fair Value

See Note 5 in our Notes to Consolidated Financial Statements for a discussion regarding the fair value measurement of our investments at December 31, 2025 and 2024.

(d)Allowance for Expected Credit Losses

See Note 14 in our Notes to Consolidated Financial Statements for a discussion regarding the allowance for expected credit losses at December 31, 2025 and 2024.

(e)Premiums

We recognize premiums as revenue, net of ceded reinsurance amounts, on a daily pro rata basis over the contract period of the related policies that are in force. For any portion of premiums not earned at the end of the reporting period, we record an unearned premium liability.

Premiums receivable represents amounts due from our policyholders for billed premiums and related policy fees. We perform a policy-level evaluation to determine the extent to which the balance of premium receivable exceeds the balance of unearned premium. We then estimate expected credit losses based on historical trends, average default rates, current economic conditions, and reasonable and supportable forecasts of future economic conditions that affect the collectability of the reported amounts. Once these conditions have been examined, we establish an allowance for credit losses for any amounts not expected to be collected. When we receive payments on amounts previously charged off, we credit our expected credit loss expense in the period we receive the payment. There was no allowance for uncollectible premiums at December 31, 2025. The balance for allowance for uncollectible premiums totaled $26,000 at December 31, 2024.

When we receive premium payments from policyholders prior to the effective date of the related policy, we record an advance premiums liability. On the policy effective date, we reduce the advance premiums liability and record the premiums as described above.

(f)Deferred Policy Acquisition Costs

We incur policy acquisition costs that vary with, and are directly related to, the production of new business. We capitalize policy acquisition costs to the extent recoverable, then we amortize those costs over the contract period of the related policy. Such costs include, but are not limited to: incremental direct costs of contract acquisition, such as commissions, premium taxes, and other essential direct costs that would not have been incurred had a policy not been acquired or renewed.

At each reporting date, we determine whether we have a premium deficiency. A premium deficiency would result if the sum of our expected losses, deferred policy acquisition costs, reinsurance costs and policy maintenance costs (such as costs to store records and costs incurred to collect premiums and pay commissions) exceeded our related unearned premiums plus investment income. Should we determine that a premium deficiency exists, we would write off the unrecoverable portion of deferred policy acquisition costs and record a liability to the extent the deficiency exceeded the deferred policy acquisition costs. We did not have a premium deficiency at December 31, 2025 or 2024.

54

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

(g)Debt Issuance Costs

We record our debt issuance costs associated with a recognized debt liability as a direct deduction from the carrying amount of the corresponding debt liability. These costs are then amortized over the life of the liability using the effective interest method.

(h)Long-lived Assets

i)Property and Equipment

We record our property and equipment at cost less accumulated depreciation and amortization. We use the straight-line method of calculating depreciation over the estimated useful lives of the assets. We periodically review estimated useful lives and, where appropriate, we make changes prospectively. We charge maintenance and repair costs to expense as incurred.

ii)Capitalized Software

We capitalize certain direct development costs associated with internal-use software. We amortize the capitalized software costs related to this internal-use software over their expected seven-year useful lives.

See Note 8 in our Notes to Consolidated Financial Statements for a discussion of our property, equipment and capitalized software that were held during 2025 and 2024.

iii)Impairment of Long-lived Assets

We annually review our long-lived assets, or more frequently when impairment indicators exist, including intangible assets, to determine if their carrying amounts are recoverable. If the non-discounted future cash flows expected to result from the use and eventual disposition of the assets are less than their carrying amounts, we reduce their carrying amounts to fair value and recognize an impairment loss.

(i)Unpaid Losses and Loss Adjustment Expenses

Our reserves for unpaid losses represent the estimated ultimate cost of settling all reported claims plus all claims we incurred related to insured events that have occurred as of the reporting date, but that policyholders have not yet reported to us.

We estimate our reserves for unpaid losses using individual case-basis estimates for reported claims and actuarial estimates for incurred but not reported (IBNR) claims, and we continually review and adjust our estimated losses as necessary based on our historical experience and as we obtain new information. If our unpaid loss reserves prove to be deficient or redundant, we increase or decrease the liability in the period in which we identify the difference, thereby impacting net income (loss). Though our estimate of the ultimate cost of settling all reported and unreported claims may change at any point in the future, a reasonable possibility exists that our estimate may vary significantly in the near term from the estimated amounts included in our consolidated financial statements.

On our Consolidated Balance Sheets, we report our reserves for unpaid losses gross of the amounts related to unpaid losses recoverable from reinsurers. On our Consolidated Statements of Comprehensive Income (Loss), we report losses net of amounts ceded to reinsurers. We do not discount our loss reserves for financial statement purposes.

(j)Segment Reporting

Operating segments are components of our business about which separate financial information is available and evaluated by our Chief Operating Decision Maker (CODM) in decisions regarding resource allocations and financial performance assessments. Generally, financial information is required to be reported on the basis that is used internally for evaluating segment performance and deciding how to allocate resources to each segment. Segments are determined based on differences in products, internal reporting, and how operational decisions are made.

55

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

As described in Note 1, as a result of the sale of IIC, we disclose one reportable operating segment, which consists of our commercial lines business. The details of our commercial lines business is described in Part 1, Item 1, above.

Our CODM is our President and CEO. Our CODM uses net income that is also reported on the Consolidated Statements of Comprehensive Income (Loss) to make decisions on how to allocate resources, for example deciding whether to reinvest profits for items such as product development or acquisitions, or whether to pay dividends. Net income is used to monitor budget versus actual results. Net income is also used in competitive analysis by benchmarking against our peers. This analysis is used in assessing performance of our operating segment and in establishing targets for management.

In addition, our measure of segment assets is reported on the Consolidated Balance Sheets as total assets. The accounting policies of our operating segment are the same as those described in our summary of significant accounting policies.

Revenue, profit or loss and significant segment expenses can be seen on the Consolidated Statements of Comprehensive Income (Loss). Additional reconciliation of certain expenses can be seen within Note 3, below.

(k)Goodwill

Goodwill is the excess of cost over the estimated fair value of net assets acquired. We attribute all goodwill associated with our acquisitions to one reporting segment.

Goodwill is not amortized but is tested for impairment at least annually, or more frequently if events or circumstances, such as adverse changes in the business climate, indicate that there may be justification for conducting an interim test. The goodwill impairment process requires a comparison of the estimated fair value of a reporting segment to its carrying value. We test goodwill for impairment by performing a quantitative assessment. In performing the quantitative impairment test, we use a discounted cash flow valuation approach.

The discounted cash flow valuation approach requires judgments about revenues, operating earnings projections, capital market assumptions and discount rates. The key inputs, judgments and assumptions necessary in determining estimated fair value of the reporting segment include projected operating earnings, current book value, the level of economic capital required to support the mix of business, long-term growth rates, comparative market multiples, control premium, the account value of in-force business, projections of new and renewal business, as well as margins on such business, the level of interest rates, credit spreads, equity market levels, and the discount rate that we believe is appropriate for the respective reporting segment.

The valuation methodology utilized is subject to key judgments and assumptions that are sensitive to change. Estimates of fair value are inherently uncertain and represent only management’s reasonable expectation regarding future developments. These estimates and the judgments and assumptions upon which the estimates are based will, in all likelihood, differ in some respects from actual future results. Declines in the estimated fair value of our reporting segments could result in goodwill impairments in future periods, which could materially adversely affect our results of operations or financial position.

For the 2025, 2024 and 2023 annual goodwill impairment tests we utilized the quantitative assessment, determining that the goodwill was not impaired for the reporting segment.

(l)Intangible Assets

Identifiable intangible assets that are amortized generally represent the cost of client relationships, trade names and agency agreements acquired. In valuing these assets, we make assumptions regarding useful lives and projected growth rates, and significant judgment is required. We periodically review identifiable intangibles for impairment as events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. If the carrying amounts of the assets exceed their respective fair values, additional impairment tests are performed to measure the amount of the impairment loss, if any.

Non-amortizing intangible assets generally represent the cost of insurance licenses acquired. Non-amortizing intangible assets are tested for impairment in the fourth quarter of each fiscal year by comparing the fair value of the licenses acquired to their carrying values. We established fair value for purposes of impairment testing using the income approach. If the carrying value of a license

56

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

acquired exceeds its fair value, an impairment loss is recognized equal to that excess. During 2025, 2024 and 2023, we determined that the fair values of all remaining intangible assets were not impaired.

(m)Leases

We evaluate if a leasing arrangement exists upon inception of a contract. A contract contains a lease if the contract conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. Identified property, plant or equipment for all of our leases are physically distinct and explicitly identified. In addition, we assess whether a contract implicitly contains the right to control the use of a tangible asset that is not already owned.

Our leases expire at various dates and may contain renewal options. Our leases do not contain termination options. The exercise of lease renewal options are at our sole discretion and are only included in the determination of the lease term if we are reasonably certain to exercise the option. Our lease agreements do not contain any material residual value guarantees or restrictive covenants.

Right-of-use assets and lease liabilities are based on the present value of the minimum lease payments over the lease term. We have elected the practical expedient related to lease and non-lease components, as an accounting policy election for our office equipment leases, which allows a lessee to not separate non-lease from lease components and instead account for consideration received in a contract as a single lease component. We have also elected the practical expedients to exclude leases considered to be short-term and with values that fall under our capitalization threshold.

A portion of our lease agreements includes variable lease payments which are not recorded in the initial measurement of the lease liability and right-of-use asset balances. Our office equipment lease agreements may include variable payments based on usage of the equipment.

We utilized discount rates to determine the present value of the lease payments based on information available at the commencement date of the lease. We used an incremental borrowing rate based on factors such as lease term to determine the appropriate present value of future lease payments, as the rate implicit in the lease is not always readily available. When determining the incremental borrowing rate, we considered the rate of interest we would pay on a secured borrowing in an amount equal to the lease payments for the underlying asset under similar terms.

(n)Income Taxes

We recognize deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. We measure deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which we expect to recover or settle those temporary differences. Should a change in tax rates occur, we recognize the effect on deferred tax assets and liabilities in operations in the period that includes the enactment date. Refer to Note 15 for additional information. Realization of our deferred income tax assets depends upon our generation of sufficient future taxable income.

We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant taxing authority. We recognize interest accrued related to uncertain tax benefits and penalties as income tax expense. As of December 31, 2025, we have no accrued penalties or interest related to uncertain tax benefits.

57

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

In June 2022, we assessed our deferred tax position and believed it was more likely than not that the benefit from certain net operating loss (NOL) carryforwards, net capital operating loss carryforwards and other net deferred tax assets would not be realized. In recognition of this risk, we recorded a valuation allowance against these deferred tax assets as of June 30, 2022. During the second quarter of 2023, we evaluated our position based on the results of our continuing operations and determined that it was more likely than not that we would be able to realize the benefit from our NOL carryforwards and business tax credit carryforwards and reversed the valuation allowance on the Company’s deferred tax assets, with the exception of the deferred tax assets attributable to capital loss carryforward amounts and other capital asset inventory items, as well as the deferred tax assets related to the dual consolidated losses of the Company’s Bermuda subsidiaries. As of December 31, 2025, we still have a valuation allowance on these items. The Company continues to evaluate its position as it relates to the valuation allowance on its deferred tax assets.

On May 15, 2023, we entered into the Tax Memorandum with DFS. As a result of this Memorandum, any benefit received from the use of UPC's net operating losses is due to the DFS as the receiver of UPC. The expense related to this remittance is presented within our provision for income taxes on our Consolidated Statements of Comprehensive Income (Loss), offsetting the tax benefit recognized.

Pillar Two, the global minimum tax initiative from the Organization for Economic Co-operation and Development, requires Multinational Enterprises to pay a 15% tax on income in each country that they operate. A “top-up tax” on the parent company of a multinational group for any income earned by a subsidiary in a low-tax jurisdiction that falls below the 15% minimum tax rate must be accrued. The Company is currently doing business in the U.S., the Cayman Islands and Bermuda. The Cayman Islands does not have a corporate income tax, while Bermuda has enacted a corporate income tax, becoming effective for tax years on or after January 1, 2025. The Pillar Two legislation provides for transitional relief for multinational groups that are in the initial phase of their international activity. This transitional relief can be available until the tax year beginning January 1, 2030. For companies that are in the initial phase of its international activity, any potential “top-up” tax is reduced to zero. It has been determined that the Company qualifies for this transitional relief for 2024 and 2025 and therefore the Company has not included any additional income tax expense in its financial statements related to the Pillar Two global minimum tax rules for 2024 or 2025.

On December 27, 2023, the Bermuda Government passed the Corporate Income Tax Act 2023, conforming to the OECD BEPS Pillar 2 framework. This act enacts a 15% corporate income tax that will generally become effective for Bermuda domiciled entities on or after January 1, 2025. The legislation provides for a number of exemptions, including a limited international presence exemption, which can defer the effective date until January 1, 2030, if the consolidated group operates in six or fewer jurisdictions, has less than €50 million in tangible assets located within Bermuda, and none of its Bermuda entities are subject to the Income Inclusion Rule in any other jurisdiction. As of December 31, 2025, the Company determined that none of its Bermuda domiciled entities were subject to the Bermuda Corporate Income Tax for the tax year ending on December 31, 2025, and would not be subject to the tax for the tax year ending December 31, 2026. The Company will continue to evaluate if and when its Bermuda domiciled entities become subject to the Bermuda Corporate Income Tax.

On July 4, 2025, President Trump signed law, H.R. 1, One Big Beautiful Bill Act (“OBBBA”). The Company identified four key corporate income tax items in the OBBBA that could impact our business: (1) the modification of IRC Section 163(j) for tax years beginning after December 31, 2025, by permanently restoring the EBITDA-based calculation, (2) the creation of IRC Section 174A, which permits businesses to immediately expense (deduct) domestic research and experimental (R&E) costs in the year incurred, starting with tax years beginning after December 31, 2024, permanently reversing the 2017 Tax Cuts and Jobs Act (TCJA) mandate that forced the amortization of domestic R&D costs over 5 years), (3) the restoration of 100% bonus depreciation for qualified property acquired and placed in service after January 19, 2025, and (4) an amendment to IRC Section 170, which, for tax years beginning on or after January 1, 2026, limits corporate charitable contribution deductions by imposing a new 1% floor on taxable income. Contributions are now only deductible to the extent they exceed 1% of the corporation’s taxable income, while maintaining the 10% overall deduction cap. It was determined that the corporate income tax changes resulting from the One Big Beautiful Bill Act will not have a material impact on the Company’s financial statements.

58

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

We did not incur any material tax penalties or income-tax-related interest during the years ended December 31, 2025, 2024 or 2023. Tax penalties or income-tax-related interest incurred are included in our provision (benefit) for income taxes on our Consolidated Statements of Comprehensive Income (Loss).

(o)Advertising Costs

We expense all advertising costs as an operating expense when we incur those costs. For the years ended December 31, 2025, 2024 and 2023, we incurred advertising costs of $90,000, $41,000, and $29,000, respectively.

(p)Earnings Per Share (EPS)

We report both basic EPS and diluted EPS. To calculate basic EPS, we divide net income (loss) attributable to ACIC common stockholders (net income (loss) less the net income (loss) attributable to noncontrolling interests (NCI)) by the weighted-average number of shares of common stock outstanding during the period. We calculate diluted EPS using the treasury method by dividing net loss attributable to ACIC common stockholders by the weighted-average number of shares of common stock, common stock equivalents, and restricted shares outstanding during the period. Common share equivalents are only included when they are dilutive.

(q)Concentrations of Risk

Our current operations subject us to the following concentrations of risk:

•a concentration of revenue because we write only property insurance policies;

•a concentration of revenue because we source 97% of our commercial lines business from AmRisc, LLC (AmRisc);

•a geographic concentration resulting from the fact that 100% of our business is in Florida;

•a group concentration of credit risk with regard to our reinsurance recoverable, since all of our reinsurers engage in similar activities and have similar economic characteristics that could cause their ability to repay us to be similarly affected by changes in economic or other conditions; and

•a concentration of credit risk with regard to our cash, because we choose to deposit all of our cash at five financial institutions.

We mitigate our geographic and group concentrations of risk by entering into reinsurance contracts with financially stable reinsurers, and by securing irrevocable letters of credit from reinsurers when necessary.

With regard to our cash balances held at financial institutions, we had $291,030,000 and $196,930,000 in excess of Federal Deposit Insurance Corporation insurance limits at December 31, 2025 and 2024, respectively.

(r)Managing General Agent Fees

Our policy fees consist of the managing general agent (MGA) fee. We defer MGA fees as unearned revenue and recognize revenue on a pro rata basis over the term of the underlying policies.

(s)Reinsurance

We follow industry practice of reinsuring a portion of our risks. Reinsurance involves transferring, or “ceding”, all or a portion of the risk exposure on policies we write to another insurer, known as a reinsurer. To the extent that our reinsurers are unable to meet the obligations they assume under our reinsurance agreements, we remain liable for the entire insured loss.

Our reinsurance agreements are short-term, prospective contracts. We record an asset, ceded unearned premiums, and a liability, reinsurance payable, for the entire contract amount upon commencement of our new reinsurance agreements. We amortize our ceded unearned premiums over the 12-month contract period.

We record provisional ceding commissions that we receive in connection with our reinsurance contracts for all underwriting years as an offset to deferred acquisitions costs.

We record amounts recoverable from our reinsurers on paid losses plus an estimate of amounts recoverable on unpaid losses. The estimate of amounts recoverable on unpaid losses is a function of our liability for unpaid losses associated with the reinsured policies;

59

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

therefore, the amount changes in conjunction with any changes to our estimate of unpaid losses. Though our estimate of amounts recoverable from reinsurers on unpaid losses may change at any point in the future because of its relation to our reserves for unpaid losses, a reasonable possibility exists that our estimate may change significantly in the near term from the amounts included in our consolidated financial statements.

We estimate uncollectible amounts receivable from reinsurers based on an assessment of factors including the creditworthiness of the reinsurers and the adequacy of collateral obtained, where applicable. As of December 31, 2025 and December 31, 2024, our ending credit loss allowance related to reinsurance recoverables was $30,000, and $75,000, respectively.

(t)Assessments

Pursuant to Florida Statute 631.57, the state has the ability to levy assessments against insurers. We record guaranty fund and other insurance-related assessments imposed upon us as an expense in the period the regulatory agency imposes the assessment. To recover Florida Insurance Guaranty Association (FIGA) assessments, we calculate and begin collecting a policy surcharge that will allow us to collect the entire assessment over a 12-month period, based on our estimate of the number of policies we expect to write. We then submit an information-only filing to the insurance regulatory authority requesting formal approval of the policy FIGA surcharge. The process may be repeated in successive 12-month periods until we collect the entire assessment. We record the recoveries as revenue in the period that we collect the cash. While current regulations allow us to recover from policyholders the amount of assessments imposed upon us, our payment of the assessments and our recoveries may not offset each other in the same fiscal period in our consolidated financial statements.

Where permitted by law or regulatory authority, we collect assessments imposed upon policyholders as a policy surcharge and we record the amounts collected as a liability until we remit the amounts to the regulatory agency that imposed the assessment. During 2023, we received a multi-year emergency assessment notice from FIGA. This assessment will be 1.0% on direct written premiums of all covered lines of business in Florida beginning October 1, 2023 through September 20, 2025 to cover the cost of insurance for companies facing insolvency. During 2025, FIGA extended this assessment for a third year, beginning October 1, 2025 through September 30, 2026.

(u)Discontinued Operations

As described in Note 1, on May 9, 2024, we entered into the Sale Agreement with Forza in which ACIC agreed to sell and Forza agreed to acquire 100% of the issued and outstanding stock of IIC. Forza’s application to acquire IIC was approved by the NYDFS on February 13, 2025 and the sale closed on April 1, 2025.

As described in Note 4, effective February 27, 2023, our former subsidiary, UPC, was placed into receivership with the DFS. This receivership divested our ownership of UPC. This disposal, as well as the activities related directly to supporting the business conducted by UPC, qualified as a discontinued operation. The results of operations of business are reported as discontinued operations when the disposal represents a strategic shift that will have a major effect on the entity's operations and financial results. When a business is identified for discontinued operations reporting:

•Results for prior periods are retroactively reclassified as discontinued operations;

•Results of operations are reported in a single line, net of tax, in the Consolidated Statements of Comprehensive Income (Loss); and

•Assets and liabilities are reported as held for disposal in the Consolidated Balance Sheets.

Additional details by major classification of operating results and financial position are included in Note 4.

(v)Accounting Pronouncements

Recently Adopted Policies

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07, Segment Reporting (Topic 280) Improvements to Reportable Segments Disclosures. This update requires the disclosure of significant

segment expenses that are part of an entity’s segment measure of profit or loss and regularly provided to the CODM. In addition, it adds or makes clarifications to other segment-related disclosures, such as clarifying that the disclosure requirements in ASC 280 are for entities with a single reportable segment and that an entity may disclose multiple measures of segment profit and loss. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 and interim periods beginning after December 15, 2024, with early adoption permitted. We adopted this guidance as of December 31, 2024 and have included all required disclosures in Note 2(j) above.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740) Improvements to Income Tax Disclosures. This update amends the Codification to enhance the transparency and decision usefulness of income tax disclosures. This ASU requires additional disaggregation of the reconciliation between the statutory and effective tax rate for an entity and of income taxes paid, both of which are disclosures required by current GAAP. The amendments improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU 2023-09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. We adopted this guidance, retrospectively, as of December 31, 2025 and have included all required disclosures.

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. This update modernizes certain aspects of the accounting for and disclosure of software costs under ASC 350-40. ASU 2025-06 is effective for annual periods beginning after December 31, 2027, with early adoption permitted. We adopted this guidance as of December 31, 2025 and have included all required disclosures.

Pending Policies

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 2024-40): Disaggregation of Income Statement Expenses. This update requires disaggregated disclosure of income statement expenses for entities. The ASU does not change the expense captions an entity presents on the face of the income statement; rather, it requires disaggregation of certain expense captions into specified categories in disclosures within the footnotes to the financial statements. ASU 2024-03 is effective for all entities for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. We are assessing the impact of this new accounting standard on our consolidated financial statements and related disclosures.

3)DISAGGREGATION OF RELEVANT EXPENSE CAPTIONS

We present our expenses in four major captions, loss and loss adjustment expenses, policy acquisition costs, general and administrative expenses and interest expense. We have presented the disaggregation of our general and administrative expenses below for the years ended December 31, 2025, 2024, and 2023 to enhance disclosure regarding our recast general and administrative expenses.

On August 25, 2022, we announced that our former subsidiary, UPC, had filed plans for withdrawal in the states of Florida, Louisiana, and Texas and intended to file a plan for withdrawal in the state of New York. All filed plans entailed non-renewing personal lines policies in these states. Additionally, we announced that Demotech, an insurance rating agency, notified UPC of its intent to withdraw UPC's Financial Stability Rating. On December 5, 2022, the FLOIR issued Consent Order No. 303643-22-CO that provided for the administrative supervision and approval of the plan of run-off for UPC (the "Consent Order"). The Consent Order provided formal approval of UPC's Plan of Run-Off (the "Plan") to facilitate a solvent wind down of its affairs in an orderly fashion. On February 10, 2023, we announced that a solvent run-off of UPC was unlikely, driven by Hurricane Ian losses which exhausted UPC's reinsurance coverage. On February 27, 2023, UPC was placed into receivership with the DFS, which divested our ownership of UPC.

In the first quarter of 2023, the assets and liabilities of UPC were divested. In addition, activities provided by our entities, SCS, SLS and UIM, related directly to supporting the business conducted by UPC, were included. The assets and liabilities for the balance sheet as of the date of disposal are retrospectively reclassified as held for disposal, and the results of UPC and activities related directly to supporting the business conducted by UPC are classified as discontinued operations for all periods presented. This activity was included in our personal lines operating segment in previous filings.

(1) The Company divested its ownership on February 27, 2023, the date the DFS was appointed as receiver of the entity.

During the first quarter of 2024, due to a change in fact pattern, the Company evaluated its capitalized software, previously classified as held for disposal at December 31, 2023. As a result of this evaluation, it was determined that the use case of the software by the Company shifted. The Company has reclassified this asset and the associated amortization expense in the current period presented within this footnote in accordance with GAAP guidance, resulting in amortization expense for the capitalized software being captured in continuing operations prospectively. Property and equipment of $8,095,000 at December 31, 2023 was also reclassed at March 31, 2024, before first quarter amortization.

There were no other non-cash transactions during the years ended December 31, 2025 and 2024. During the year ended December 31, 2023, amortization attributed to discontinued operations totaled $3,544,000.

When we sell investments, we calculate the gain or loss realized on the sale by comparing the sales price (fair value) to the cost or adjusted/amortized cost of the security sold. We determine the cost or adjusted/amortized cost of the security sold using the specific-identification method.

Portfolio monitoring

We have a quarterly portfolio monitoring process to identify and evaluate each fixed-income security whose carrying value may be impaired as the result of a credit loss. For each fixed-income security in an unrealized loss position, if we determine that we intend to sell the security or that it is more likely than not that we will be required to sell the security before recovery of the cost or amortized cost basis for reasons such as liquidity needs or contractual or regulatory requirements, the security's entire decline in fair value is recorded in earnings.

67

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

If our management decides not to sell the fixed-income security and it is more likely than not that we will not be required to sell the fixed-income security before recovery of its amortized cost basis, we evaluate whether the decline in fair value has resulted from credit losses or other factors. This is typically indicated by a change in the rating of the security assigned by a rating agency, and any adverse conditions specifically related to the security or industry, among other factors. If the assessment indicates that a credit loss may exist, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses will be recorded in earnings. Credit loss is limited to the difference between a security's amortized cost basis and its fair value. Any additional impairment not recorded through an allowance for credit losses is recognized in other comprehensive income (loss).

During the years ended December 31, 2025 and 2024, we determined that none of our fixed-income securities shown in the table below that are in an unrealized loss position have declines in fair value that result from credit losses. Therefore, no credit loss allowance was recorded at December 31, 2025 and 2024. The issuers of our debt security investments continue to make interest payments on a timely basis. We do not intend to sell, nor is it likely that we would be required to sell the debt securities before we recover our amortized cost basis. Equity securities are reported at fair value with changes in fair value recognized in the valuation of equity investments.

The following table presents aging of our unrealized investment losses by investment class:

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. The hierarchy for inputs used in determining fair value maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Assets and liabilities

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

recorded on our Consolidated Balance Sheets at fair value are categorized in the fair value hierarchy based on the observability of inputs to the valuation techniques as follows:

Level 1: Assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market that we can access.

Level 2: Assets and liabilities whose values are based on the following:

(a)Quoted prices for similar assets or liabilities in active markets;

(b)Quoted prices for identical or similar assets or liabilities in markets that are not active; or

(c)Valuation models whose inputs are observable, directly or indirectly, for substantially the full term of the asset or liability.

Level 3: Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. Unobservable inputs reflect our estimates of the assumptions that market participants would use in valuing the assets and liabilities.

We estimate the fair value of our investments using the closing prices on the last business day of the reporting period, obtained from active markets such as the NYSE, Nasdaq and NYSE American. For securities where quoted prices in active markets are unavailable, we use a third-party pricing service that utilizes quoted prices in active markets for similar instruments, benchmark interest rates, broker quotes and other relevant inputs to estimate the fair value of those securities for which quoted prices are unavailable. Our estimates of fair value reflect the interest rate environment that existed as of the close of business on December 31, 2025 and 2024. Changes in interest rates subsequent to December 31, 2025, may affect the fair value of our investments.

The fair value of our fixed maturities is initially calculated by a third-party pricing service. Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of proprietary models, produce valuation information in the form of a single fair value for individual fixed income and other securities for which a fair value has been requested. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, liquidity spreads, currency rates and other information, as applicable. Credit and liquidity spreads are typically implied from completed transactions and transactions of comparable securities. Valuation service providers also use proprietary discounted cash flow models that are widely accepted in the financial services industry and similar to those used by other market participants to value the same financial information. The valuation models take into account, among other things, market observable information as of the measurement date, as described above, as well as the specific attributes of the security being valued, including its term, interest rate, credit rating, industry sector and, where applicable, collateral quality and other issue or issuer-specific information. Executing valuation models effectively requires seasoned professional judgment and experience.

Any change in the estimated fair value of our fixed-income securities would impact the amount of unrealized gain or loss we have recorded, which could change the amount we have recorded for our investments and other comprehensive income (loss) on our Consolidated Balance Sheets as of December 31, 2025.

(1) Other common stocks in the fair value hierarchy exclude these common stock interests that are measured at estimated fair value using the net asset value per share (or its equivalent) practical expedient.

(2) Other investments included in the fair value hierarchy exclude these other limited partnership interests that are measured at estimated fair value using the net asset value per share (or its equivalent) practical expedient.

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis, meaning, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). There were no financial instruments measured on a non-recurring basis at December 31, 2025 and 2024.

The carrying amounts for the following financial instrument categories approximate their fair values at December 31, 2025 and 2024, because of their short-term nature: cash and cash equivalents, accrued investment income, premiums receivable, reinsurance recoverable, reinsurance payable, other assets, and other liabilities. The carrying amount of our Senior Notes (defined below) approximates fair value, as the interest rates and terms are variable.

We are responsible for the determination of fair value and the supporting assumptions and methodologies. We have implemented a system of processes and controls designed to provide assurance that our assets and liabilities are appropriately valued. For fair values received from third parties, our processes are designed to provide assurance that the valuation methodologies and inputs are appropriate and consistently applied, the assumptions are reasonable and consistent with the objective of determining fair value, and the fair values are accurately recorded.

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

At the end of each quarter, we determine whether we need to transfer the fair values of any securities between levels of the fair value hierarchy and, if so, we report the transfer as of the end of the quarter. During 2025 and 2024, we transferred no investments between levels.

For our investments in U.S. government securities that do not have prices in active markets, agency securities, state and municipal governments and corporate bonds, we obtain the fair values from our investment custodians, which use a third-party valuation service. The valuation service calculates prices for our investments in the aforementioned security types on a month-end basis by using several matrix-pricing methodologies that incorporate inputs from various sources. The model the valuation service uses to price U.S. government securities and securities of states and municipalities incorporates inputs from active market makers and inter-dealer brokers. To price corporate bonds and agency securities, the valuation service calculates non-call yield spreads on all issuers, uses option-adjusted yield spreads to account for any early redemption features, and adds final spreads to the U.S. Treasury curve at 3 p.m. (ET) as of quarter end. Since the inputs the valuation service uses in its calculations are not quoted prices in active markets, but are observable inputs, they represent Level 2 inputs.

Other investments

We acquired investments in limited partnerships, recorded in the other investments line of our Consolidated Balance Sheets, and these investments are currently being accounted for at fair value utilizing a net asset value per share practical expedient. The Company has also acquired an investment in a commercial mortgage loan, which is classified as held-for-long-term-investment and a surplus note, which is classified as held-to-maturity. Both of these investments are carried on the balance sheet at amortized cost.

The information presented in the table below is as of December 31, 2025 and 2024:

	Book Value				Unrealized Gain				Unrealized Loss				Fair Value
December 31, 2025
Limited partnership investments (1)	$	5,024			$	1,093			$	—			$	6,117

(1) Distributions will be generated from investment gains, from operating income, from underlying investments of the funds and from liquidation of the underlying assets of the funds. We estimate that the underlying assets of the funds will be liquidated over the next few months to five years.

During the second quarter of 2025, the Company invested $6 million in a surplus note, as seen in the table above. As a term of this investment, the Company was issued 18,497 warrants to purchase common stock of the issuer of the surplus note for no additional consideration. These warrants are free-standing in nature and are not being used as a hedging instrument. The Company does not invest in derivatives as part of its investment strategy and is only a holder of these warrants as a product of its strategy to invest in this surplus note.

As the underlying common stock of the warrants is not publicly traded and the issuer of the warrants has been in operation for less than one year, the fair value to these warrants is not material as of December 31, 2025. For the year ended December 31 2025, these warrants had no impact on the Company's financial position, financial performance or cash flows.

Restricted Cash

We are required to maintain assets on deposit with various regulatory authorities to support our insurance operations. The cash on deposit with state regulators is available to settle insurance liabilities. We also use trust funds in certain reinsurance transactions.

10)REINSURANCE

Our catastrophe reinsurance programs are designed primarily by utilizing third-party catastrophe modeling software and consulting with third-party reinsurance experts to project our exposure to catastrophe events. We evaluate modeled expected losses developed by the catastrophe modeling software using our risk portfolio data to estimate probable maximum losses ("PML") across multiple return periods and the average annual loss. The Company monitors and manages its catastrophe risk using this model output along with other internal and external data sources, such as our historical loss experience and industry loss experience, to develop our view of catastrophe risk.

Our catastrophe reinsurance coverage consists of three separate placements:

1.AmCoastal’s core catastrophe reinsurance program, including catastrophe bonds (effective April 2024 and December 2024), in effect June 1 through May 31, annually, which includes excess of loss and quota share treaties providing coverage for catastrophe losses from named or numbered windstorms;

2.AmCoastal’s all other perils catastrophe excess of loss agreement in effect January 1 through December 31, annually, which provides protection from catastrophe loss events other than named or numbered windstorms and earthquakes; and

3.AmCoastal's catastrophe aggregate excess of loss coverage, in effect Jan 1 through December 31, annually, which provides protection from all catastrophe loss events, including named windstorms, severe convective storms and winter storm events.

This reinsurance protection is an essential part of our catastrophe risk management strategy. It is intended to provide our stockholders with an acceptable return on the risks assumed by our insurance entity, and to reduce the variability of earnings, while providing surplus protection. Although reinsurance agreements contractually obligate our reinsurers to reimburse us for the agreed-upon portion of our gross paid losses, they do not discharge our primary liability. In the event one or more of our reinsurers fail to fulfill their obligation, the surplus of our statutory entity may decline, and we may not be able to fulfill our obligation to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. Additionally, we face the risk that actual losses incurred from one or more catastrophic events may be above the modeled expected loss resulting in losses exceeding our reinsurance coverage, which may result in a decline in surplus, and as a result we may not be able to fulfill our obligations to policyholders, or we may not be able to maintain compliance with various regulatory financial requirements. The details of our programs and the likelihood of a catastrophic event exceeding these two coverages are outlined below.

74

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

AmCoastal’s core catastrophe reinsurance program provides occurrence-based coverage up to an exhaustion point of approximately $1,330,000,000 for a first occurrence and $1,676,000,000 in the aggregate. Under this program, the Company's GAAP retention on a first event is $29,750,000 ($14,000,000 retained by AmCoastal under statutory accounting principles (STAT retained), $15,750,000 (retained separately by the Company's captive)). The Company has purchased second and third event retrocession coverage, reducing its second event GAAP retention to $18,500,000 ($14,000,000 STAT retained by AmCoastal, $4,500,000 retained separately by the Company's captive) and third event GAAP retention to $3,750,000, based on three $100,000,000 loss events. AmCoastal’s program provides sufficient coverage for approximately a 1-in-203-year return period, indicating that the probability of a single occurrence exceeding protection purchased is roughly 0.5% estimated by blending the AIR 10, AIR 11.5, RMS 22 and RMS 23 catastrophe models using long-term catalogs including demand surge and based on total insured value at September 30, 2025 of $69 billion. AmCoastal’s program also provides sufficient coverage for a 1-in-100-year event followed by a 1-in-50-year event in the same treaty year, the probability of which is less than 0.1%. While we believe these catastrophe models are very good tools and their output provides reasonable proxies for the probability of exhausting our reinsurance protections, they are imperfect, so actual results could vary dramatically from those expected.

AmCoastal’s all other perils catastrophe excess of loss agreement provides protection from catastrophe loss events other than named windstorms and earthquakes up to $88,200,000 for a first and second event, totaling $176,400,000 in the aggregate. This agreement provides sufficient coverage for approximately a 1-in-450-year return period, indicating that the probability of a single occurrence exceeding protection purchased is no more than 0.2%.

In addition to the programs described above, AmCoastal purchased a new catastrophe aggregate excess of loss coverage (the “CAT Agg” agreement) to mitigate our catastrophe frequency risk. This agreement provides coverage for in-force, new and renewal business. Effective January 1, 2025, the new CAT Agg agreement provides $40,000,000 of aggregate limit (with a $20,000,000 per occurrence cap) in excess of zero after the $40,000,000 annual aggregate deductible has been met. The CAT Agg agreement limits our losses from all catastrophe loss events, including named windstorms, severe convective storms and winter storm events for the full year ending December 31, 2025.

Effective December 15, 2023, we agreed to commute a private reinsurer’s share of core catastrophe reinsurance coverage and replace this gap in coverage with new coverage provided by one of our other private reinsurers. This transaction resulted in a reduction in expense of approximately $6,300,000 and $15,700,000 during the three and six months ended June 30, 2024, respectively.

Where we think prudent, particularly where premium rates are high relative to the risk, we retain risk whereby AmCoastal purchases reinsurance from Shoreline Re, our captive reinsurance entity. Shoreline Re participates on AmCoastal's all other perils catastrophe excess of loss agreement and AmCoastal's excess per risk agreement. In addition, Shoreline Re participates in a 45% quota share agreement with AmCoastal, which provides coverage for all catastrophe perils as well as attritional losses incurred.

The table below outlines the participation of Shoreline Re for each program, including premium received and capital at risk.

Treaty		Effective Dates		Premium Collected / Cession Rate				Capital at Risk (1)

Ceded losses incurred decreased by $201,982,000 during the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily as a result of Hurricane Milton from which we incurred an ultimate loss estimate of $125,000,000 at December 31, 2024. In 2025 we incurred no similar catastrophe activity and this estimated was revised down to $75,500,000 at December 31, 2025.

11)LIABILITY FOR UNPAID LOSSES AND LOSS ADJUSTMENT EXPENSE (LAE)

We generally use the term loss(es) to collectively refer to both loss and LAE. We establish reserves for both reported and unreported unpaid losses that have occurred at or before the balance sheet date for amounts we estimate we will be required to pay in the future. Our policy is to establish these loss reserves after considering all information known to us at each reporting period. At any given point in time, our loss reserve represents our best estimate of the ultimate settlement and administration cost of our insured claims incurred and unpaid. Since the process of estimating loss reserves requires significant judgment due to a number of variables, such as fluctuations in inflation, judicial decisions, legislative changes and changes in claims handling procedures, our ultimate liability will likely differ from these estimates. We revise our reserve for unpaid losses as additional information becomes available, and reflect adjustments, if any, in our earnings in the periods in which we determine the adjustments are necessary.

General Discussion of the Loss Reserving Process

Reserves for unpaid losses fall into two categories: case reserves and reserves for claims incurred but not reported.

•Case reserves - When a claim is reported, we establish an automatic minimum case reserve for that claim type that represents our initial estimate of the losses that will ultimately be paid on the reported claim. Our initial estimate for each claim is based upon averages of loss payments for our prior closed claims made for that claim type. Then, our claims personnel perform an evaluation of the type of claim involved, the circumstances surrounding each claim and the policy provisions relating to the loss and adjust the reserve as necessary. As claims mature, we increase or decrease the reserve estimates as deemed necessary by our claims department based upon additional information we receive regarding the loss, the results of on-site reviews and any other information we gather while reviewing the claims.

•Reserves for losses incurred but not reported (IBNR reserves) - Our IBNR reserves include true IBNR reserves plus “bulk” reserves. Bulk reserves represent additional amounts that cannot be allocated to particular claims, but which are necessary to estimate ultimate losses on reported and unreported claims. We estimate our IBNR reserves by projecting the ultimate losses using the methods discussed below and then deducting actual loss payments and case reserves from the projected ultimate losses. We review and adjust our IBNR reserves on a quarterly basis based on information available to us at the balance sheet date.

December 31, 2025

When we establish our reserves, we analyze various factors, such as our historical loss experience and that of the insurance industry, claims frequency and severity, our business mix, our claims processing procedures, legislative enactments, judicial decisions and legal developments in imposition of damages, and general economic conditions, including inflation. A change in any of these factors from the assumptions implicit in our estimates will cause our ultimate loss experience to be better or worse than indicated by our reserves, and the difference could be material. Due to the interaction of the aforementioned factors, there is no precise method for evaluating the impact of any one specific factor in isolation, and an element of judgment is ultimately required. Due to the uncertain nature of any projection of the future, the ultimate amount we will pay for losses will be different from the reserves we record. However, in our judgment, we employ techniques and assumptions that are appropriate, and the resulting reserve estimates are reasonable, given the information available at the balance sheet date.

To determine our ultimate losses, we first use multiple actuarial techniques to establish a range of reasonable estimates. These techniques are in line with actuarial standards of practice and actuarial literature. A brief overview of each of these techniques is provided below. We then make additional qualitative considerations for many of the previously mentioned factors and select a point within this range. These ultimate loss estimates include reserves for both reported and unreported claims.

Estimation of the Reserves for Unpaid Losses and Allocated LAE

We calculate our estimate of ultimate losses with the following actuarial methods. The methods are applied to paid and incurred loss data. Incurred losses are defined as paid losses plus case reserves. For our loss reserving process, the word “segment” refers to a subgrouping of our claims data, such as by geographic area and/or by particular line of business; it does not refer to operating segments.

•Development Method - The development method is based upon the assumption that the relative change in a given year’s loss estimates from one evaluation point to the next is similar to the relative change in prior years’ reported loss estimates at similar evaluation points. In utilizing this method, actual annual historical loss data is evaluated. Loss development factors (LDFs) are calculated to measure the change in cumulative losses from one evaluation point to the next. These historical LDFs and comparable industry benchmark factors form the basis for selecting the LDFs used in projecting the current valuation of losses to an ultimate basis. When applied to incurred loss data, the implicit assumption is that the relative adequacy of case reserves has been consistent over time, and that there have been no material changes in the rate at which claims have been reported. Applying this method to paid losses avoids potential distortions in the data due to changes in case reserving methodology, and also loses any potentially useful information contained in the current case reserves. The paid development method’s implicit assumption is that the rate of payment of claims has been relatively consistent over time.

•Expected Loss Method - Ultimate loss projections are based upon a prior measure of the anticipated losses, usually relative to a measure of exposure (such as earned house years). An expected loss cost is applied to each year’s measure of exposure to determine estimated ultimate losses for that year. Actual losses are not considered in this calculation. Because the ultimate loss estimates do not change unless the exposures or loss costs change, this method has the advantage of being stable over time. However, the advantage of this stability is offset by a lack of responsiveness, as this method does not consider actual loss experience as it emerges. This method assumes that the loss cost per unit of exposure is a good indication of ultimate losses. It can be entirely dependent on pricing assumptions (e.g., historical experience adjusted for loss trend).

•Bornhuetter-Ferguson Method - The Bornhuetter-Ferguson (B-F) method is a credibility weighting procedure that blends the responsiveness of the Development Method with the stability of the Expected Loss Method by setting ultimate losses equal to actual losses plus the expected unreported losses, which are based on the Expected Loss Method. As an experience year matures, actual losses gradually move closer to their ultimate levels so reliance on the Expected Loss Method can be reduced.

•Paid-to-Paid Development Method - In addition to the aforementioned methods, we also rely upon the Paid-to-Paid Development Method to project ultimate unallocated loss adjustment expense (ULAE). Ratios of paid ULAE to paid loss and allocated loss adjustment expense are compiled by calendar year and a paid-to-paid ratio selection is made. The selected ratio is applied to the estimated IBNR amounts and one half of this ratio is applied to case reserves. This method is derived from rule of thumb that half of ULAE is incurred when a claim is opened and the other half is incurred over the remaining life of the claim.

Reliance and Selection of Methods

Each of these methods has its own strengths and weaknesses that depend upon the circumstances of the segment and the age of the claims experience we analyze. The nature of our book of business allows us to place substantial, but not exclusive, reliance on the loss development methods, and the selected LDFs represent the most critical aspect of our loss reserving process. We use the same set of LDFs in the methods during our loss reserving process that we use to calculate the premium necessary to pay expected ultimate losses.

Reasonably Likely Changes in Variables

As previously noted, we evaluate several factors when exercising our judgment in the selection of the LDFs that ultimately drive the determination of our loss reserves. The process of establishing our reserves is complex and necessarily imprecise, as it involves using judgment that is affected by many variables. We believe a reasonably-likely change in almost any of these aforementioned factors could have an impact on our reported results, financial condition and liquidity. However, we do not believe any reasonably likely changes in the frequency or severity of claims would have a material impact on us.

On an annual basis, our consulting actuary issues a statement of actuarial opinion that documents the actuary’s evaluation of the adequacy of our unpaid loss obligations under the terms of our policies. We review the analysis underlying the consulting actuary’s opinion and compare the projected ultimate losses to our own estimates to ensure that the reserve for unpaid losses recorded at each annual balance sheet date is based upon all internal and external factors related to known and unknown claims against us, and to ensure our reserve is within guidelines promulgated by the National Association of Insurance Commissioners (NAIC).

Our commercial lines claims are handled by Sedgwick Delegated Authority (“SDA”) pursuant to a servicing agreement with AmRisc, as AmCoastal’s exclusive managing general agent for condominium business and Skyway Underwriters as managing general agent for apartment business. We maintain a claims management team that focuses on statutory claim compliance and overall customer satisfaction on these claims. When AmRisc or Skyway Underwriters receive a claim, it sends notification to SDA and our claims team. SDA triages all incoming claims to determine whether they can be desk-adjusted or whether SDA will assign the fieldwork to third-party claims adjusting companies. The third-party claims adjusting companies conduct inspections of the damaged property and prepare initial estimates. SDA reviews the reports to determine whether there is a covered loss to be paid to the policyholder in accordance with the terms and conditions of the policy in effect. We have established an authority level with SDA to settle claims on our behalf. If a loss amount exceeds this authority, the approval elevates to AmRisc or Skyway Underwriters for review, and ultimately, to our team for final review if the loss exceeds AmRisc’s established authority level. Our claims team monitors all claims throughout the claims-handling process, regardless of the loss amount.

The following is information about incurred claims development and paid claims development as of December 31, 2025, excluding adjusting and other expenses, net of reinsurance, as well as cumulative claim frequency and the total of IBNR liability plus expected development on reported claims included within the net incurred claims amounts. Please note that a portion of our business is subject to a loss cap which may have been allocated to the incurred table below in a different period than the payment is reflected in the paid table. This may result in a decrease in incurred claims year-over-year. The incurred claims development and paid claims development data reflects the acquisitions of AmCo in April 2017, on a retrospective basis (includes AmCo data for years prior to our acquisition of the insurance affiliates). The information about incurred claims development and paid claims development for the years ended December 31, 2015 to 2024 is presented as supplementary information.

Based upon our internal analysis and our review of the statement of actuarial opinion provided by our actuarial consultants, we believe that the reserve for unpaid losses reasonably represents the amount necessary to pay all claims and related expenses which may arise from incidents that have occurred as of the balance sheet date.

As reflected in the table above, we had favorable development in all three years related to prior year losses. This favorable development came as a result of re-estimating ultimate losses in each year based on our initial reserves being higher than the ultimate settlements. The loss payments made by the Company during the year ended December 31, 2024 were higher than the loss payments made during the year ended December 31, 2025 due to the settling of prior year catastrophe claims, with no similar catastrophe activity occurring in 2025. Total reserves and reinsurance recoverable on unpaid losses also decreased when compared to the prior period, as a result of catastrophe reserves continuing to go down as we settle these claims.

12)LONG-TERM DEBT

Senior Notes Payable

On December 13, 2017, we issued $150,000,000 of 10-year senior notes (the Senior Notes) that will mature on December 15, 2027 and bear interest at a rate equal to 6.25% per annum payable semi-annually on each June 15 and December 15, commencing June 15, 2018. The Senior Notes are senior unsecured obligations of the Company. We may redeem the Senior Notes at our option, at any time and from time to time in whole or in part, prior to September 15, 2027, at a redemption price equal to the greater of (i) 100% of the principal amount of the notes to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon from the date of redemption to the date that is three months prior to maturity. On or after that date, we may redeem the Senior Notes at par, plus accrued and unpaid interest thereon. On December 8, 2022, the Kroll Bond Rating Agency, LLC announced a downgrade of our issuer and debt ratings from BBB- to BB+. As a result, pursuant to our agreement, the interest rate of our Senior Notes increased from 6.25% to 7.25%. On July 21, 2025, the Kroll Bond Rating Agency, LLC announced an upgrade of the Company's issuer and debt ratings from BB+ to BBB-. As a result, pursuant to the Company's indenture, the interest rate of its Senior Notes decreased from 7.25% to 6.25% effective December 16, 2025.

Financial Covenants

Our Senior Notes provide that the Company and its subsidiaries shall not incur any indebtedness unless no default exists and the Company’s leverage ratio as of the last day of any annual or quarterly period (the balance sheet date) immediately preceding the date on which such additional indebtedness is incurred would have been no greater than 0.3:1, determined on a pro forma basis as if the additional indebtedness and all other indebtedness incurred since the immediately preceding balance sheet date had been incurred and the proceeds therefrom applied as of such day. The Company and its subsidiaries also may not create, assume, incur or permit to exist any indebtedness for borrowed money that is secured by a lien on the voting stock of any significant subsidiary without securing the Senior Notes equally. The Company may not issue, sell, assign, transfer or otherwise dispose of, directly or indirectly, any of the capital stock of the Company’s significant subsidiaries as of the issue date of the Senior Notes (except to the Company or to one or more of the Company’s other subsidiaries, or for the purpose of qualifying directors or as may be required by law or regulation), subject to certain exceptions. At December 31, 2025, while our leverage ratio was greater than the allowed ratio above, we did not incur any additional debt during the period and as a result we were in compliance with the covenants in the Senior Notes.

At December 31, 2025, the annual maturities of our long-term debt were as follows:

13)COMMITMENTS AND CONTINGENCIES

Litigation

We are involved in claims-related legal actions arising in the ordinary course of business. We accrue amounts resulting from claims-related legal actions in unpaid losses and LAE during the period that we determine an unfavorable outcome becomes probable and we can estimate the amounts. Management makes revisions to our estimates based on its analysis of subsequent information that we receive regarding various factors, including: (i) per claim information; (ii) company and industry historical loss experience; (iii) judicial decisions and legal developments in the awarding of damages; and (iv) trends in general economic conditions, including the effects of inflation.

On October 20, 2023, the Company received notice that the Florida Department of Financial Services ("DFS") filed a notice of claim and demand for tender of policy limits under the Company's director and officer insurance policy (the “Claim”). The Claim alleges that former officers and directors of UPC were involved in wrongful acts that resulted in UPC's insolvency. The Claim demands immediate tender of the Company's director and officer’s policy limit of $40,000,000 where the Company has a retention of $1,500,000. The former directors and officers of UPC deny the allegations. Although no litigation has arisen from the Claim, litigation is anticipated. The directors and officers plan to vigorously defend against the Claim, however, due to the Company's indemnification obligation, during 2023, the Company accrued the policy retention amount of $1,500,000.

Subleases

We previously leased and occupied office space in which we no longer operate. Effective October 1, 2022, this office space was subleased to a third party. The sublease was effective from October 1, 2022 through July 31, 2025, with no option to extend. However, on February 29, 2024, this sublease was cancelled as a part of an agreement to terminate the original lease associated with the office space. As of December 31, 2024, we recognized $33,000 of income related to this sublease, exclusive of the lease expense associated with the original lease.

Employee Retention Credit

A series of legislation was enacted in the United States during 2020 and 2021 in response to the COVID-19 pandemic that provided financial relief for businesses impacted by government-mandated shutdowns, work stoppages, or other losses suffered by employers. The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) provided an employee retention credit, which is a refundable tax credit against certain employment taxes of up to $5,000 per employee for eligible employers. The tax credit is equal to 50% of qualified wages paid to employees during a quarter, capped at $10,000 of qualified wages per employee. During the second quarter of 2022, we evaluated our eligibility and filed for a $10,161,000 refund in connection with our Employee Retention Tax Credit for the tax year ended December 31, 2021. During the year ended December 31, 2025, we have received refunds of $4,469,000 that were outstanding as of December 31, 2024. These were recorded as a contra-expense to payroll tax in the periods received. With these receipts, as of December 31, 2025, the Company has received all requested funds from the Internal Revenue Service related to this refund and no longer has an unrecorded gain contingency related to this balance.

Quota Share Commission Loss Contingency

AmCoastal participates in shared quota-share reinsurance agreements with our former subsidiary, UPC, which are subject to a variable ceding commission based on loss experience. With the receivership of UPC in 2023, data related to UPC losses is limited and infrequent and could shift AmCoastal’s commission related to these contracts unfavorably. We cannot reasonably determine how this shift will be allocated between the contracted parties. Any updated calculations must be provided to both our reinsurance partners and the DFS as receiver of UPC. We are unable to estimate the impact; however, we believe a loss contingency related to these commissions may exist as of December 31, 2025.

We will continue to monitor the matter for further developments that could affect the outcome of these contingencies and will make any appropriate adjustments each quarter.

14)ALLOWANCE FOR EXPECTED CREDIT LOSSES

We are exposed to credit losses primarily through three different pools of assets based on similar risk characteristics: premiums receivable for direct written business, reinsurance recoverables from ceded losses to our reinsurers and our investment holdings. We estimate the expected credit losses based on historical trends, credit ratings assigned to reinsurers by rating agencies and debt issuers, average default rates, current economic conditions, and reasonable and supportable forecasts of future economic conditions that affect the collectability of the reported amounts over its expected life. Changes in the relevant information may significantly affect the estimates of expected credit losses.

The allowance for credit losses is deducted from the amortized cost basis of the assets to present their net carrying value at the amount expected to be collected. Each period, the allowance for credit losses is adjusted through earnings to reflect expected credit losses over the remaining lives of the assets.

(1) For the years ended December 31, 2025 and 2023, the state of Florida makes up the majority (greater than 50%) of our state and local income tax effects. For the year ended December 31, 2024, the states of Florida and Louisiana make up the majority (greater than 50%) of our state and local income tax effects.

(2) The foreign rate differential is calculated by taking pretax net income times the foreign tax rate less the US federal statutory rate. For the years ended December 31, 2025, 2024, and 2023, our foreign tax rate is 0% and the US federal statutory rate is 21%. For the years ended December 31, 2025, 2024 and 2023, our pretax income related to the Cayman Islands is $38,639,000, $11,732,000, and $17,966,000, respectively.

Information regarding our income tax payments, net of refunds, can be found in the supplemental cash flows information section of our Consolidated Statement of Cash Flows above.

Deferred income taxes, which are included in other assets or other liabilities as appropriate, reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes.

As of December 31, 2025, we had net operating loss (NOL) carryforwards. The amount and timing of realizing the benefits of NOL carryforwards depend on future taxable income and limitation imposed by tax laws. There is no expiration for $2,000 of our Federal NOL carryforward. The remaining $6,767,000 of our Federal NOL carryforward will begin expiring in 2042 and will fully expire by the end of 2042. There is no expiration for $2,000 of our Florida NOL carryforward. The remaining $6,473,000 of our Florida NOL carryforward will begin expiring in 2042 and will fully expire by the end of 2042. Our other state NOL carryforwards of $3,065,000 will begin expiring in 2043 and will fully expire by the end of 2044. The unused business tax credits of $1,610,000 will begin expiring in 2037 and will fully expire by the end of 2040.

Net deferred tax asset (liability) is included in the financial statements as follows:

		Year Ended December 31,
		2025				2024
Continuing operations		$	(7,552	)		$	2,931
Discontinued operations			—				—
Net deferred tax asset (liability)		$	(7,552	)		$	2,931

We had a valuation allowance of $20,246,000 and $43,212,000 at December 31, 2025 and 2024, respectively. At December 31, 2025, the entire valuation allowance is attributable to our continuing operations. The change in valuation allowance includes a $20,895,000 decrease in valuation allowance charged to continuing operations tax expense and a $2,071,000 decrease of valuation allowance on our FAS 115 assets which is charged to other comprehensive income. In assessing the net realizable value of deferred tax assets, we consider whether it is more likely than not that we will not realize some portion or all of the deferred tax assets. The ultimate realization of deferred tax assets depends upon the generation of future taxable income during the periods in which those temporary differences become deductible. We considered taxable income (loss), reversals of temporary items, projected future taxable income and tax planning strategies in making this assessment.

As of June 30, 2022, the Company established a valuation allowance against its capital deferred tax inventory, which included unrealized gains and losses on investments (FAS 115 balances). Under ASC 740-10-45-20, the effect of a change in the beginning-of-the-year balance of a valuation allowance should be charged to income from continuing operations. Changes in deferred tax on FAS 115 balances are generally charged to Accumulated Other Comprehensive Income (AOCI), so booking a portion of the valuation allowance to deferred tax expense creates a disproportionate tax effect on AOCI. As a result of the valuation allowance, the Company has a disproportionate tax effect on AOCI beginning with the period ending June 30, 2022. When the Company releases this disproportionate tax effect, it results in an income tax benefit in the income statement. The Company is using the “aggregate portfolio approach” to clear the disproportionate tax effect. Under this approach, the disproportionate tax effect remains intact as long as the

87

investment portfolio remains. Only upon the disposal of the entire portfolio is the disproportionate tax effect cleared from AOCI. During 2024, the disproportionate tax effects related to the portfolio of UPC (an entity no longer included in the Consolidated financial statements of the Company) were cleared from the Company’s AOCI account and charged to discontinued operations. The disproportionate tax effects attributable to the remaining investment portfolio of the Company remain intact as of December 31, 2025.

The statute of limitations related to our consolidated Federal income tax returns and our Florida income tax returns expired for all years up to and including 2021; therefore, only the 2022 through 2025 tax years remain subject to examination by the taxing authorities. During the year ended December 31, 2023, we were examined by the IRS regarding tax years 2018, 2019 and 2020. This exam was completed in 2023, and no adjustments were proposed.

ACIC’s reinsurance subsidiaries, which are based in the Cayman Islands and Bermuda, made an irrevocable election under section 953(d) of the U.S. Internal Revenue Code of 1986, as amended, to be treated as a domestic insurance company for U.S. Federal income tax purposes. As a result of this election, our reinsurance subsidiaries are subject to United States income tax on its worldwide income as if it were a U.S. corporation.

The following is a reconciliation of the beginning and ending amount of unrecognized tax benefits for the year ended December 31, 2025:

		December 31, 2025
Balance at January 1		$	666
Decrease based on tax positions related to prior years			—
Balance at December 31		$	666

Included in the balance at December 31, 2025 was $666,000 of unrecognized tax benefits that, if recognized, would affect the annual effective tax rate.

16)STATUTORY ACCOUNTING AND REGULATION

The insurance industry is heavily regulated. State laws and regulations, as well as national regulatory agency requirements, govern the operations of all insurers such as our insurance subsidiary. The various laws and regulations require that insurers maintain minimum amounts of statutory surplus and risk-based capital, restrict insurers' ability to pay dividends, specify allowable investment types and investment mixes, and subject insurers to assessments. AmCoastal is domiciled and operates in Florida and at December 31, 2025, and during the year then ended, met all regulatory requirements of the state.

During 2023, we received a multi-year emergency assessment notice from FIGA. This assessment will be 1.0% on direct written premiums of all covered lines of business in Florida beginning October 1, 2023 through September 30, 2025 to cover the cost of insurance companies facing insolvency. During 2025, FIGA extended this assessment for a third year, beginning October 1, 2025 through September 30, 2026.

The NAIC has RBC guidelines for insurance companies that are designed to assess capital adequacy and to raise the level of protection that statutory surplus provides for policyholders. Most states, including Florida, have enacted statutory requirements adopting the NAIC RBC guidelines, and insurers having less statutory surplus than required will be subject to varying degrees of regulatory action, depending on the level of capital inadequacy. State insurance regulatory authorities could require an insurer to cease operations in the event the insurer fails to maintain the required statutory capital.

The state laws of Florida permit an insurer to pay dividends or make distributions out of that part of statutory surplus that is derived from net operating profit and net realized capital gains. The state laws further provide calculations to determine the amount of dividends or distributions that can be made without the prior approval of the insurance regulatory authorities in those states and the amount of dividends or distributions that would require prior approval of the insurance regulatory authorities in those states. Statutory RBC requirements may further restrict our insurance subsidiary's ability to pay dividends or make distributions if the amount of the intended dividend or distribution would cause statutory surplus to fall below minimum RBC requirements.

Governmental agencies or certain quasi-governmental entities can levy assessments upon us in the states in which we write policies. See Note 2(t) for a description of how we recover assessments imposed upon us. We expense an assessment when the particular governmental agency or quasi-governmental entity levies it upon us; therefore, expected recoveries are not assets and we will record the amounts as income when collected from policyholders.

Governmental agencies or certain quasi-governmental entities can also levy assessments upon policyholders, and we collect the amount of the assessments from policyholders as surcharges for the benefit of the assessing agency. We collect $4 per commercial policy written in the state of Florida on behalf of the Florida Emergency Management Preparedness and Assistance Trust Fund.

Our insurance subsidiary must maintain capital and surplus ratios or balances as determined by the FLOIR. At December 31, 2025, we met these requirements. The table below details the amount of surplus as regards policyholders for AmCoastal at December 31, 2025 and 2024.

		December 31, 2025				December 31, 2024
Surplus as regards policyholders		$	316,594			$	230,001

AmCoastal's restricted net assets at December 31, 2025 total $253,108,000.

NAIC law limits an insurer's investment in equity instruments and also restricts investments in medium-to-low quality debt instruments. We were in compliance with all investment restrictions at December 31, 2025 and 2024.

We have reported our insurance subsidiary's assets, liabilities and results of operations in accordance with GAAP, which varies from statutory accounting principles prescribed or permitted by state laws and regulations, as well as by general industry practices. The following items are principal differences between statutory accounting and GAAP:

•Statutory accounting requires that we exclude certain assets, called non-admitted assets, from the balance sheet.

•Statutory accounting requires us to expense policy acquisition costs when incurred, while GAAP allows us to defer to the extent realizable and amortize policy acquisition costs over the estimated life of the policies.

•Statutory accounting requires that surplus notes, also known as surplus debentures, be recorded in statutory surplus, while GAAP requires us to record surplus notes as a liability.

•Statutory accounting allows certain investments to be carried at amortized cost or fair value based on the rating received from the Securities Valuation Office of the NAIC, while they are recorded at fair value for GAAP because the investments are held as available for sale.

•Statutory accounting allows ceding commission income to be recognized when written if the cost of acquiring and renewing the associated business exceeds the ceding commissions, but under GAAP, such income is deferred and recognized over the coverage period.

•Statutory accounting requires that unearned premiums and loss reserves are presented net of related reinsurance, rather than on a gross basis under GAAP.

•Statutory accounting requires a provision for reinsurance liability be established for reinsurance recoverable on paid losses aged over ninety days and for unsecured amounts recoverable from unauthorized reinsurers. Under GAAP, there is no charge for uncollateralized amounts ceded to a company not licensed in the insurance subsidiary’s domiciliary state, and a reserve for uncollectible reinsurance is charged through earnings, rather than surplus or equity.

•Statutory accounting requires an additional admissibility test and the change in deferred income tax is reported directly in capital and surplus, rather than being reported as a component of income tax expense under GAAP.

December 31, 2025

In September 2023, the Company entered into an equity distribution agreement (the “Agreement”) with Raymond James & Associates, Inc., as agent (the “Agent”), relating to the issuance and sale from time to time by the Company, through the Agent, of up to 8,000,000 shares of the Company’s common stock, par value $0.0001 per share (the “Shares”). Sales of the Shares under the Agreement will be made in sales deemed to be “at the market offerings”. The Agent is not required to sell any specific amount of Shares but agreed to act as the Company’s sales agent for a commission equal to 3.0% of the gross proceeds from the sales of the Shares. As of December 31, 2025, 4,373,000 shares have been sold under the Agreement, resulting in commissions paid of approximately $1,181,000 and net proceeds of approximately $38,190,000. The Agreement will terminate upon the issuance and sale of all Shares subject to the Agreement, or the Agreement may be suspended or discontinued at any time.

During the year ended December 31, 2025, the Company received a dividend of $23,000,000 from our insurance subsidiary, AmCoastal. During December 2024, the Company received a $14,300,000 dividend from our insurance subsidiary, AmCoastal.

In July 2019, our Board of Directors authorized a stock repurchase plan of up to $25,000,000 of our common stock. As of December 31, 2025, we had not yet repurchased any shares under this stock repurchase plan but we may from time to time repurchase shares of common stock pursuant to 10b5-1 plans, open market purchases, privately negotiated transactions or by other methods. The timing and volume of repurchases are at the discretion of management, based on the capital needs of the business, the market price of ACIC common stock, and general market conditions. The plan has no expiration date, and the plan may be suspended or discontinued at any time.

See Note 20 for information regarding our stock-based compensation activity.

20)STOCK-BASED COMPENSATION

We account for stock-based compensation under the fair value recognition provisions of ASC Topic 718 - Compensation - Stock Compensation. We recognize stock-based compensation cost over the award’s requisite service period on a straight-line basis for time-based restricted stock grants and performance-based restricted stock grants. We record forfeitures as they occur for all stock-based compensation.

Under the Company’s 2013 Omnibus Incentive Plan, 1,000,000 shares were authorized for issuance at December 31, 2020. In 2020, the Board of Directors adopted the 2020 Omnibus Incentive Plan, which was approved by shareholders during our 2020 Annual Meeting of Stockholders. At the time of approval, an additional 2,000,000 shares were authorized for issuance. In 2024, the 2020 Omnibus Incentive Plan was amended and approved by shareholders during the 2024 Annual Meeting of Stockholders, authorizing an additional 2,000,000 shares for issuance.

The following table presents our total stock-based compensation expense:

	Year Ended December 31,
	2025				2024				2023
Employee stock-based compensation expense
Pre-tax (1)	$	3,798			$	2,097			$	1,082
Post-tax (2)		3,000				1,657				855
Director stock-based compensation expense
Pre-tax (1)		501				448				174
Post-tax (2)		396				354				137

(1) This table does not include withholding of vested shares for tax liabilities, which totaled $1,855,000, $1,359,000 and $24,000 in 2025, 2024, and 2023, respectively.

(2) The after-tax amounts are determined using the 21% corporate federal tax rate.

We had approximately $3,887,000 of unrecognized stock compensation expense at December 31, 2025 related to non-vested stock-based compensation granted, which we expect to recognize over a weighted-average period of approximately 1.8 years. We had approximately $183,000 of unrecognized director stock-based compensation expense at December 31, 2025, related to non-vested director stock-based compensation granted, which we expect to recognize over a weighted-average period of approximately 0.4 years.

Restricted stock, restricted stock units and performance stock units

AMERICAN COASTAL INSURANCE CORPORATION

Notes to Consolidated Financial Statements

December 31, 2025

Stock-based compensation cost for restricted stock awards, restricted stock units and performance stock units is measured based on the closing fair market value of our common stock on the date of grant, which vest in equal installments over the requisite service period of typically three years. Restricted stock awards granted to non-employee directors vest over a one-year period. Each restricted stock unit and performance stock unit represents our obligation to deliver to the holder one share of common stock upon vesting.

Performance stock units vest based on the Company’s return on average equity compared to a defined group of peer companies. On the grant date, we issue the target number of performance stock units. They are subject to forfeitures if performance goals are not met. The actual number of performance stock units earned can vary from zero to 150 percent of the target for the 2025, 2024, and 2023 awards.

We granted 466,672, 598,713 and 45,000 shares of restricted common stock, which had a weighted-average grant date fair value of $11.48, $7.41 and $5.25 per share during the years ended December 31, 2025, 2024, and 2023, respectively. Additionally, during the year ended December 31, 2023, the Company granted 262,933 shares of restricted common stock, with a fair value of $4.33 per share, which were contingent upon stockholder approval of an increase in the number of shares of our common stock that may be issued pursuant to the 2020 Omnibus Incentive Plan. This increase was approved during our 2024 Annual Meeting of Shareholders and the impact of the contingent grants is included in the granted shares described above and seen in the table below.

The following table presents certain information related to the activity of our non-vested common stock grants:

	Number of Restricted Shares				Weighted Average Grant Date Fair Value
Outstanding as of December 31, 2022		714,239			$	2.73

(1) Contingent shares granted during 2023 have been included in the calculation of 2024’s granted values.

Stock options

Stock option fair value was estimated on the grant date using the Black-Scholes-Merton formula. Stock options vest in equal installments over the requisite service period of typically three years. The following weighted-average assumptions were used to value the stock options granted:

	2025				2024
Expected annual dividend yield		—	%			—	%
Expected volatility		88.51	%			86.92	%
Risk-free interest rate		3.87	%			4.37	%
Expected term	6 years				6 years

The expected annual dividend yield for our options granted during 2025 and 2024 is based on no dividends being paid in future quarters. The expected volatility is a historical volatility calculated based on the daily closing prices over a period equal to the expected term. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the grant date. Expected term takes into account the three-year graded vesting term and the 10-year contractual term of the option.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a set of disclosure controls and procedures designed to ensure that information required to be disclosed in reports we file or submit under the Securities Exchange Act of 1934, as amended (Exchange Act) is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. We designed our disclosure controls with the objective of ensuring we accumulate and communicate this information to our management, including our principal executive officer and principal financial and accounting officer, as appropriate, to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of the design and operations of our disclosure controls and procedures, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of December 31, 2025, the end of the period covered by this report. Based on our evaluation, our principal executive officer and principal financial and accounting officer concluded that our disclosure controls and procedures were effective.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over our financial reporting. Internal control over financial reporting is defined in Rules 13a-15(f) and 15d-15(f) promulgated under the Exchange Act, as a process to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles in the United States. Internal control over financial reporting includes those policies and procedures that: (a) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and dispositions of our assets; (b) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (c) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on our financial statements.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making this assessment, our management used the criteria set forth in the Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. Based on our evaluation under that framework, management concluded that our internal control over our financial reporting was effective as of December 31, 2025.

Deloitte & Touche LLP, our independent registered public accounting firm that audited the consolidated financial statements included in this Form 10-K, has issued their attestation report on our internal control over financial reporting, which is included herein.

Changes in Internal Control over Financial Reporting

During the year ended December 31, 2025, there was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in connection with the evaluation of our internal control performed during the year ended December 31, 2025, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Controls

Because of the inherent limitations of internal controls, we do not expect our disclosure controls and procedures or our internal control over financial reporting will prevent or detect all errors 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 our objectives will be met. Further, no evaluation of controls can provide absolute assurance that we will prevent all misstatements due to error or fraud or that we will detect all control issues and instances of fraud, if any, within our company.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of American Coastal Insurance Corporation

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of American Coastal Insurance Corporation and subsidiaries (the "Company") 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). 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 COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial statements as of and for the year ended December 31, 2025, of the Company and our report dated March 9, 2026, expressed an unqualified opinion on those 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 Annual Report on Internal Control 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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.
