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

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.

16

AMERICAN COASTAL INSURANCE CORPORATION

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.

18

AMERICAN COASTAL INSURANCE CORPORATION

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.

19

AMERICAN COASTAL INSURANCE CORPORATION

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.

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 bycybersecurity 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 OFCOMMON 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.

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.

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.

Effect of current year catastrophe losses on combined ratio 0.5 % 9.3 % 4.9 %

Effect of prior year development on combined ratio (1.9 )% (1.4 )% (4.9 )%

(1) Loss ratio, net, is calculated as losses and LAE net of losses ceded to reinsurers, relative to net premiums earned. Management uses this operating metric to analyze our loss trends and believes it is useful for investors to evaluate this component separately from our other operating expenses.

(2) Expense ratio is calculated as the sum of all operating expenses less interest expense relative to net premiums earned. Management uses this operating metric to analyze our expense trends and believes it is useful for investors to evaluate these components separately from our loss expenses.

(3) Combined ratio is the sum of the loss ratio, net and expense ratio. Management uses this operating metric to analyze our total expense trends and believes it is a key indicator for investors when evaluating the overall profitability of our business.

(4) Underlying combined ratio, a measure that is not based on GAAP, is reconciled above to the combined ratio, the most directly comparable GAAP measure. Additional information regarding non-GAAP financial measures presented in this Form 10-K can be found in “Definitions of Non-GAAP Measures”, below.

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.

Year Ended December 31,

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.

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:

Estimated Fair Value Percent of Total Estimated Fair Value Percent of Total

States, municipalities and political subdivisions 27,078 4.2 17,197 3.2

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.

We amortize our ceded unearned premiums over the annual agreement period, and we record that amortization in ceded premiums earned on our Consolidated Statements of Comprehensive Income (Loss). The table below summarizes the amounts of our ceded premiums written under the various types of agreements, as well as the amortization of ceded unearned premiums:

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.

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) investing activities 620 (179,211 ) (2,544 )

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:

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.

43

AMERICAN COASTAL INSURANCE CORPORATION

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:

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.

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:

o

Testing 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.

o

Performing 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.

o

Performing 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.
