Fidelis Insurance Group – 2024 CEO Letter CEO Letter Dear Fellow Shareholders, As I reflect on the achievements of 2024, Fidelis Insurance Group made significant progress in strengthening all aspects of our business and enhancing the value proposition that we deliver to our stakeholders. I am proud of our team’s efforts to build on this strong foundation and we continue to demonstrate the benefits of our capital strength, scale, lead positioning and deep rooted relationships. Throughout the year, we capitalized on high- quality, profitable underwriting opportunities, delivered significant top-line growth, and expanded our diversified portfolio, including the addition of new distribution channels such as Lloyd’s Syndicate 3123, engaging with new clients across new geographies. Additionally, we returned excess capital to our shareholders through the initiation of our dividend policy and share repurchase program. Our strategic asset allocation and focused approach to optimizing our investment portfolio within our risk appetite led to increased investment income. Furthermore, we welcomed our first partners outside of our cornerstone relationship with The Fidelis Partnership, marking a pivotal step in our growth and diversification strategy. Our goal remains to further strengthen Fidelis’ position as a leading global specialty insurer by leveraging strategic partnerships to deliver compelling returns through the cycle. As we enter 2025, we are well-capitalized and positioned to drive profitable growth. Our underwriting talent, market access, financial strength and disciplined approach to capital management will continue to differentiate our business and enable us to deliver sustainable value for all our stakeholders. “We enter 2025 well-capitalized and positioned to drive profitable growth.” 1 $4.8bn Cash & Invested Assets $3.0bn Total Capital $4.4bn Total Gross Premiums Written (GPW) 23.0% GPW Growth YOY $11.8bn Total Assets 2024 FINANCIAL RESULTS

Fidelis Insurance Group – 2024 CEO Letter 2024 FINANCIAL RESULTS In 2024, we delivered on our growth objectives for the year, increasing gross premiums written 23% to $4.4 billion with a renewal price index (RPI) across our portfolio of 111%. In our Insurance segment, gross premiums written increased 20% to $3.5 billion, driven primarily by our direct property, marine, and structured credit insurance portfolios. Reinsurance premiums grew 40% to $865 million, as we capitalized on favorable market conditions. We generated a combined ratio of 99.7%, operating net income of $137 million, and operating return on average equity (ROAE) of 5.6%. These results are inclusive of net adverse prior year period development in our Aviation and Aerospace line of business during the fourth quarter related to business underwritten in Add 2021 and 2022 (pre- bifurcation) and impacted by the ongoing Russia-Ukraine aviation litigation. In respect of the aviation litigation, we have been judiciously settling claims to de-risk our overall exposure – lowering potential downside risk and providing greater certainty to our shareholders. Excluding this net adverse prior year development, we would have exceeded our long-term ROAE target. Our net investment income increased to $191 million, growing 59% from 2023 driven by an increase in investible assets and a higher earned yield on our fixed income portfolio and cash balances. We ended the year with $11.8 billion in total assets and $4.8 billion in cash and invested assets. Our book value per diluted common share was $21.79 at year end 2024. Taking into account the $0.40 common share dividends paid in 2024, this is an increase of 7.2% from the end of 2023. 2 A FOCUS ON DELIVERING PROFITABLE UNDERWRITING In 2024, our gross premiums written growth reflected both strong retention rates and continued expansion through new business, demonstrating the benefits of our scale, capital strength, and lead positioning across a high-quality, mature portfolio of specialty insurance and reinsurance risks. Our Insurance segment includes the major specialty lines of business and other highly tailored products, where the buying motivation is often driven by regulatory capital relief, capital efficiency or transaction facilitation. Our Reinsurance segment consists of an actively managed, property reinsurance book, providing reinsurance worldwide on a proportional or excess of loss basis.

This allows us to maintain a disciplined and nimble approach to underwriting. We believe this underwriting strategy allows us to deliver attractive risk- adjusted returns over the long term by managing through cycles and strategically deploying capital to the most attractive market opportunities. Additionally, we also pursued opportunities for growth through new origination channels to broaden the footprint of our business and to continue driving growth across our Insurance and Reinsurance lines of business. This included entering Lloyd’s through a variable quota share with a focused participation in The Fidelis Partnership Syndicate 3123, providing access to an enhanced ratings platform, global licensing and Lloyd’s only business. We also continued to diversify into new markets, including gaining direct access to Middle Eastern business through The Fidelis Partnership’s new Abu Dhabi office, creating opportunities with new clients. While The Fidelis Partnership remains our cornerstone partner and the benchmark for any new partnership is high, we have also announced new strategic partnerships to diversify and strengthen our portfolio. Commencing January 1, 2025, our partnership with Euclid Mortgage provides an opportunity to support a new partner with proven expertise in an attractive line of business. Additionally, our small capped quota share of Traveler’s cyber book adds another component to our relationship with Travelers. A DISCIPLINED APPROACH TO CAPITAL MANAGEMENT We ended the year with a strong, highly rated balance sheet and total capital of $3.0 billion. Active capital management remains a cornerstone of our strategy as we focus on proactively managing and allocating capital to maintain our financial strength, drive profitable underwriting, and create value for our shareholders. “We focus on proactively managing and allocating capital to maintain our financial strength, drive profitable underwriting, and create value for our shareholders.” In 2024, our strong capital position enabled us to pursue strategic growth opportunities, while also opportunistically Gross Premiums Written

Fidelis Insurance Group – 2024 CEO Letter returning excess capital to shareholders. We continue to believe investing in our business and deploying capital into attractive underwriting opportunities will deliver the best returns over the long-term, and this remains our top priority. Beyond this, outwards reinsurance is a key part of our strategy, serving as a flexible and aligned source of capital. In 2024, we further enhanced our overall outwards reinsurance program with the issuance of two new tranches of our Herbie Re catastrophe bond providing an additional $525 million in collateralized reinsurance protection for Named Storm and Earthquake Covered Events in the U.S. for a multi-year period. As we did in 2024, we once again renewed the majority of our outwards reinsurance protection on January 1, 2025, including our 20% whole account quota share agreement with Travelers. Finally, we remain committed to returning excess capital to our shareholders, and in 2024, we returned $152 million to common shareholders through our dividends and share repurchases. SUPPORTING OUR PEOPLE, COMMUNITIES, AND THE ENVIRONMENT Natural catastrophe losses made 2024 the sixth most costly year in insurance history. The escalating frequency of these natural disasters underscores the essential role of insurers and reinsurers, and emphasizes the necessity for premium rates and coverage terms and conditions to accurately reflect the evolving risk landscape. We are committed to taking actions with the best interests of our shareholders, customers, colleagues, and the environment in mind, and to pursue a strategy that reflects the markets in which we operate. We are also committed to supporting our employees. We know that our people are our greatest competitive advantage – they bring the extensive underwriting, capital, and investment management expertise that enables us to offer unique solutions to our customers and partners. In 2024, we welcomed Jason Kittinger as Group Chief Operating Officer, bringing a wealth of experience to bolster our operational capabilities. Jason, a seasoned professional with two decades of industry experience, has a proven track record in financial leadership and operational excellence, all of which will further strengthen our operating processes. I look forward to working closely with him in the years ahead. LOOKING AHEAD As we look ahead to 2025 and beyond, we believe we are well positioned to create long-term value for our shareholders. Even after years of compound rate improvement across most lines of business, we continue to see attractive opportunities for growth and sustained strong margins across our portfolio. Our strong balance sheet, scale, agility, and deep relationships with brokers and clients position us well to strategically pursue the opportunities that align with our risk appetite, while maintaining our disciplined approach to underwriting, investments and capital management. “We continue to see attractive opportunities for margin-accretive growth across our book.” In closing, I’d like to say thank you to my colleagues for your immense contributions this year and always, to our customers and partners for trusting in us and choosing to do business with us, and to my fellow shareholders for your continued belief and support. Sincerely, Dan Burrows Group Chief Executive Officer & Director, Fidelis Insurance Group 4

Questions and Answers about the Annual General Meeting The following are some questions that you, as a shareholder of Fidelis Insurance Holdings Limited (“FIHL”, “Fidelis”, “we” or the “Company”), may have regarding FIHL’s 2025 Annual General Meeting and brief answers to those questions. You are urged to carefully read this Information Circular in its entirety. Who is soliciting my vote? The Board of Directors of FIHL (the “Board”) is soliciting proxies to vote common shares, par value $0.01 per share (the “Common Shares”), at FIHL’s Annual General Meeting of Shareholders, which will take place on Tuesday, May 6, 2025. In connection with this solicitation, we distributed a Proxy Materials Notice to registered holders of our Common Shares on or about March 28, 2025. For beneficial owners, a Proxy Materials Notice and voting instructions are being forwarded to you by your broker, trustee or nominee. You may access the materials online by following the instructions in the Proxy Materials Notice. What items of business will be voted on at the Annual General Meeting? The items of business scheduled to be voted on at the Annual General Meeting are: ■ The election of Class II directors to FIHL’s Board for a term of three years; ■ The ratification of the appointment of KPMG Audit Limited as our independent auditor for the fiscal year ending December 31, 2025, and authorization for our Board to fix the independent auditor’s remuneration; and ■ Such other business as may properly come before the meeting. How does the Board of Directors recommend I vote? The Board recommends that you vote ‘FOR’ each of the director nominees and ‘FOR’ the ratification of the appointment of KPMG Audit Limited, an independent registered public accounting firm, to act as the Company’s independent auditor for the fiscal year ending December 31, 2025, and the authorization for our Board, acting through our Audit Committee, to fix the remuneration of the Company’s independent auditor for the fiscal year ending December 31, 2025. What shares can I vote? Each of FIHL’s Common Shares issued and outstanding as of the close of business on March 24, 2025 (the “Record Date”) for the Annual General Meeting is entitled to be voted on all items being voted upon at the Annual General Meeting. The record date for the Annual General Meeting is the date used to determine both the number of FIHL’s Common Shares that are entitled to be voted at the Annual General Meeting and the identity of the shareholders of record and beneficial owners of those Common Shares who are entitled to vote those shares at the Annual General Meeting. On the Record Date for the Annual General Meeting, we had 110,678,543 Common Shares issued and outstanding. You may vote all shares owned by you as of the Record Date for the Annual General Meeting, including (1) shares held directly in your name as the shareholder of record, and (2) shares held for you as the beneficial owner through a broker, trustee or other nominee such as a bank. 1

What is the difference between holding shares as a shareholder of record and as a beneficial owner? Voting procedures vary between record holders of shares and beneficial owners of shares. Shareholder of Record If your shares are registered directly in your name with FIHL’s transfer agent, Computershare, Inc., you are considered, with respect to those shares, the shareholder of record, and a Proxy Materials Notice is being sent directly to you by FIHL. As the shareholder of record, you have the right to grant your voting proxy directly to FIHL management or to vote in person at the Annual General Meeting. A proxy card will be available for your use by requesting a copy of proxy materials. Beneficial Owner If your shares are held in a brokerage account or by another nominee, you are considered the beneficial owner of shares held in street name, and a Proxy Materials Notice is being forwarded to you together with voting instructions. As the beneficial owner, you have the right to direct your broker, trustee or nominee how to vote and are also invited to attend the Annual General Meeting. Since a beneficial owner is not the shareholder of record, you may not vote these shares at the Annual General Meeting unless you obtain a ‘legal proxy’ from the broker, trustee or nominee that holds your shares, giving you the right to vote the shares at the meeting. Your broker, trustee or nominee should have provided voting instructions for you to use in directing the broker, trustee or nominee how to vote your shares. How can I attend the Annual General Meeting? You are entitled to attend the Annual General Meeting only if you were an FIHL shareholder as of the close of business on March 24, 2025, or you hold a valid proxy for the Annual General Meeting. The Annual General Meeting will be held on May 6, 2025, at 12:00 p.m. Atlantic Daylight Time, at the Fidelis Insurance Group Offices in Bermuda. How can I vote my shares? For each of the proposals you may vote ‘FOR’ or ‘AGAINST’ or 'ABSTAIN' from voting. Shareholder of Record: Shares Registered in Your Name If you are a shareholder of record as of March 24, 2025, you may vote at the Annual General Meeting by proxy using your proxy card, over the telephone, through the Internet or via a mobile device. Whether or not you plan to attend the Annual General Meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person even if you have already voted by proxy. To vote using the proxy card, simply complete, sign and date the proxy card and submit it promptly in accordance with the instructions therein. If you submit your signed proxy card to us before the Annual General Meeting, we will vote your shares as you direct. Your proxy card must be received by 11:59 p.m., Eastern Time on May 5, 2025, to be counted. To vote over the telephone, please dial 1-800-690-6903 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from your Proxy Materials Notice or your proxy card. Your telephone vote must be received by 11:59 p.m., Eastern Time on May 5, 2025, to be counted. 2

To vote through the Internet before the Annual General Meeting, go to www.proxyvote.com to complete an electronic proxy card. You will be asked to provide the control number from your Proxy Materials Notice or your proxy card. Your internet vote must be received by 11:59 p.m., Eastern Time on May 5, 2025, to be counted. To vote via a mobile device, on your smartphone/tablet, open the QR Reader and scan the image in the Proxy Materials Notice or the proxy card. Once the voting site is displayed, enter the 12-digit control number included on your Proxy Materials Notice or your proxy card and vote your shares. Your mobile vote must be received by 11:59 p.m., Eastern Time on May 5, 2025, to be counted. Beneficial Owner: Shares Registered in the Name of Broker or Bank If you are a beneficial owner of shares registered in the name of your broker, bank, or other agent, you should have received the Proxy Materials Notice from that organization rather than from the Company. Simply follow the instructions in the Proxy Materials Notice to ensure that your vote is counted. Alternatively, you may vote by telephone as instructed by your broker or bank. Can I change my vote? You may change your vote at any time prior to the vote at the Annual General Meeting. If you are the shareholder of record, you may change your vote by granting a new proxy bearing a later date (which automatically revokes the earlier proxy), by providing a written notice of revocation to FIHL’s Group Chief Legal Officer and Company Secretary by mail, which must be received by 11:59 p.m., Eastern Time on May 5, 2025 prior to your shares being voted in accordance with the earlier proxy, or by attending the Annual General Meeting in person and voting. Attendance at the meeting will not cause your previously granted proxy to be revoked unless you specifically so request. For shares you hold beneficially in street name, you may change your vote by submitting new voting instructions to your broker, trustee or nominee, or, if you have obtained a legal proxy from your broker or nominee giving you the right to vote your shares, by attending the meeting in person and voting. How many shares must be present or represented to conduct business at the Annual General Meeting? A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if two or more shareholders holding at least a majority of the voting power of the issued and outstanding shares entitled to vote are present at the meeting in person or represented by proxy. On the record date, there were 110,678,543 Common Shares issued and outstanding and entitled to vote. Thus, Common Shares representing at least 55,339,272 votes must be present in person or represented by proxy at the meeting to have a quorum. Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. How are votes counted? For each item of business, you may vote ‘FOR,’ ‘AGAINST’ or ‘ABSTAIN.’ If you ‘ABSTAIN,’ your abstention is not considered a vote or against the proposals and therefore has no effect on the adoption of any of the proposals. If you provide specific instructions for a given item, your shares will be voted as you instruct on such item. If you sign your proxy card or voting instruction card without giving specific instructions, your shares will be voted in accordance with the recommendations of the Board (‘FOR’ each of FIHL’s nominees to the Board, ‘FOR’ the appointment of our independent auditor and authorization for the Board to fix their remuneration, and in the discretion of the proxyholders on any other matters that properly come before the meeting). Questions and Answers 3

If you hold shares beneficially in street name and do not provide your broker with voting instructions, your shares may constitute ‘broker non-votes’. Generally, broker non-votes occur on a matter when a broker is not permitted to vote on that matter without instructions from the beneficial owner and instructions are not given. In tabulating the voting result for any particular proposal, shares that constitute broker non-votes are not considered entitled to vote on that proposal. Thus, broker non-votes will not affect the outcome of any matter being voted on at the meeting, assuming that a quorum is obtained. Shares represented by such broker non-votes will be counted in determining whether there is a quorum. What is the voting requirement to approve each of the proposals? Proposals 1 and 2 require the affirmative ‘FOR’ vote of shareholders holding more than 50% of the total votes attributable to all issued and outstanding shares entitled to vote. Is cumulative voting permitted for the election of directors? No. FIHL does not allow you to cumulate your vote in the election of directors. For all matters proposed for shareholder action at the Annual General Meeting, each Common Share issued and outstanding as of the close of business on the record date is entitled to one vote. What happens if additional matters are presented at the Annual General Meeting? Other than the items of business described in this Information Circular, we are not aware of any business to be acted upon at the Annual General Meeting. If you grant a proxy, Janice Weidenborner, or her duly appointed substitute, will have the discretion to vote your shares on any additional matters properly presented for a vote at the meeting. If, for any unforeseen reason any of our nominees are not available as a candidate for director, Janice Weidenborner, or her duly appointed substitute, will vote your proxy for such candidate or candidates as may be nominated by the Board, unless the Board chooses to reduce the number of directors serving on the Board pursuant to the Amended and Restated Bye-laws. Why did I receive a Proxy Materials Notice in the mail regarding notice of the Annual General Meeting and the Internet availability of proxy materials instead of a full set of proxy materials? As permitted under Bermuda law and our Amended and Restated Bye-laws, we are able to provide information to our shareholders by publication of an electronic record of such information on our website so long as the notice requirements in Bye-law 31 are met. We have provided notice to our shareholders of the Annual General Meeting and the availability of such related information by mailing them the Proxy Materials Notice. This saves time and costs to the Company and is in line with our environmental commitments to reduce waste. If you would like to receive a paper copy of the proxy materials, you must request one. There is no charge for such documents to be mailed to you. Please make your request for a paper copy as instructed below on or before April 21, 2025, to facilitate a timely delivery. You may also request that you receive electronic copies of all future proxy materials at www.proxyvote.com. ■ By telephone, please call 1-800-579-1639, or ■ By logging on to www.proxyvote.com, or ■ By email at: sendmaterial@proxyvote.com Please include the company name and your control number in the subject line.

PROPOSAL ONE Election of Class II Directors for Three-Year Term FIHL’s Board currently consists of 11 directors divided into three classes: Class I, Class II and Class III. The number of directors in each class is required to be as nearly equal as possible. At the 2025 Annual General Meeting, shareholders are being asked to elect four Class II directors to serve for a three-year term until the 2028 Annual General Meeting, or until their successors are elected, or until their offices are vacated in accordance with the Amended and Restated Bye-Laws. If you sign your proxy or voting instruction card or otherwise submit a proxy but do not give instructions for the voting of directors, your shares will be voted ‘FOR’ the Class II director nominees recommended by the Board. If you wish to give specific instructions for the voting of directors, you may do so by indicating your instructions on your proxy, proxy card or voting instruction card. The persons receiving the majority of ‘FOR’ votes represented by FIHL’s Common Shares will be elected. The nominees are recommended by the Board, and the Board expects that the nominees will be available to serve as directors. If for any unforeseen reason the Board’s nominees are not available as candidates for director, the proxyholder, Janice Weidenborner, with the power to appoint her substitutes, will vote your proxy for such other candidates as may be nominated by the Board, unless the Board chooses to reduce the number of directors serving on the Board pursuant to the Amended and Restated Bye-laws.

The following table summarizes the fees for professional services rendered by KPMG Audit Limited to the Company for fiscal years ended December 31, 2024,and 2023 (in millions of dollars): 2024 2023 Audit Fees (1) 6.8 5.8 Audit-Related Fees (2) — 0.5 Total Fees 6.8 6.3 (1) Audit fees consist of fees paid to KPMG Audit Limited for the audit of the Group’s annual consolidated financial statements, reviews of quarterly consolidated financial statements, audit of annual statutory statements, and comfort letters and consent letters issued in connection with documents filed with the SEC.

Summary of Corporate Governance Practices Overview The Company’s corporate governance policies and practices are comprehensive and consistent with the guidelines and requirements of the SEC, the listing standards of the New York Stock Exchange (“NYSE”) and the applicable provisions under the U.S. Sarbanes-Oxley Act of 2002, as amended. The structure, practices and committees of the Board, including matters relating to the size, independence and composition of the Board, the election and removal of directors, requirements relating to Board action and the powers delegated to the Board committees are governed by our memorandum of association, Bye-laws and policies adopted by the Board. The Board is responsible for exercising the management, control, power and authority of the Company except as required by applicable law, the memorandum of association or the Company’s Bye-laws. The following is a summary of certain provisions of the memorandum of association, Bye-laws and policies that affect the Company’s governance. Code of Conduct The Company’s policy is that all its activities be conducted with the utmost honesty, integrity, fairness and respect and in compliance with all legal and regulatory requirements. We have adopted a Code of Ethics and Conduct (the “Code of Conduct”) that is applicable to all of our employees (including our executive officers) and our directors. The Code of Ethics and Conduct is available, free of charge, on our website at www.fidelisinsurance.com/investors. The Board is responsible for overseeing the Code of Conduct and is required to approve any waivers of the Code of Conduct applicable to any director or executive officer. Director Independence As a foreign private issuer, under the listing requirements and rules of NYSE we are not required to have independent directors on our Board of Directors, except to the extent that our Audit Committee is required to consist fully of independent directors under U.S. securities laws, subject to certain phase-in schedules. However, at least a majority of the directors holding office are independent of management of the Company, as determined by the full Board using the standards for independence established by the NYSE and, in the case of the Audit Committee, the U.S. securities laws. The Board has made these determinations based primarily on an annual review of each director’s responses to questions regarding employment and compensation history, family relationships and affiliations and discussions with the directors. The Board decides which directors are considered to be independent based on the recommendation of the Nominating and Corporate Governance Committee, which evaluates director independence based on the guidelines set forth under applicable stock exchange rules and securities laws. Our Board currently consists of eleven (11) directors, eight (8) of whom are independent. For a director to be deemed independent, the Board must affirmatively determine that he or she does not have a direct or indirect material relationship with the Company. The Board has affirmatively determined that each of Matthew Adams, Daniel Brand, Charles Collis, Christine Dandridge, Cathy Iberg, Daniel Kilpatrick, Dana LaForge and Helena Morrissey meet the definition of ‘independent director’ under the applicable rules of the NYSE Listed Company Manual. In making this determination, the Board considered the relationships that each such non-employee director has with FIHL and all other facts and circumstances that the Board deemed relevant in determining such director’s independence, including beneficial ownership of Common Shares. Corporate Governance 14

Risk Oversight The Board is responsible for overseeing our risk management process. The Board focuses on our general risk management strategy and the most significant risks facing us, as well as oversees the implementation of risk mitigation strategies by management. Our Chief Executive Officer and other executive officers regularly report to our non-executive directors and the Risk Committee and the Audit Committee to ensure effective and efficient oversight of our activities and to assist in proper risk management and the ongoing evaluation of management controls. Meetings of the Board and Director Attendance The Board meets at least four times each year, with additional meetings held to consider specific items of business or as deemed necessary. Meeting frequency and agenda items may change depending on the opportunities or risks faced by the Company. An annual general meeting will be held in each year at such time and place as the Board determines, unless FIHL elects to dispense with the holding of annual general meetings in accordance with the Companies Act. The Board is responsible for its agenda. At all regularly scheduled meetings, the independent directors hold meetings without the presence of management and the directors that are not independent. In 2024, there were four (4) regularly scheduled board meetings and two (2) special meetings for a total of six (6) board meetings. Additionally, in 2024, there were four (4) meetings of the Audit Committee, five (5) meetings of the Compensation Committee, four (4) meetings of the Nominating and Corporate Governance Committee, four (4) meetings of the Risk Committee and four (4) meetings of the Investment Committee. Insider Trading Policies We have adopted an insider trading policy to establish a framework governing the trading of FIHL’s securities or securities of certain other publicly traded companies by all our employees and directors while such persons may be in possession of material non-public information. The policy applies to all decisions to purchase, sell, give away or otherwise trade (“Transact”) in FIHL’s or certain other companies’ securities, including common shares, restricted stock units and any other securities that those companies may issue, such as preferred shares, notes, bonds and convertible securities, as well as to derivative securities relating to any of those securities (collectively, “Covered Securities”). Persons covered by this policy include all members of the Board, Board observers, executive officers, employees, contractors, consultants, and advisors who receive, in the course of their service to the FIHL, any material non-public information about FIHL (each an “Associate”), as well as their family members who reside with them, anyone who lives in the same household and other persons with whom a close relationship of trust is maintained (together with an Associate, each a “Covered Person”). The insider trading policy establishes guidelines and procedures for the following: 1.Trading Restrictions: No Covered Person can Transact in any Covered Securities while possessing material non-public information about FIHL or the Group. Covered Persons who may be in possession of such information must first consult with, and obtain the advance approval of, the Group Chief Legal Officer or Group Chief Compliance Officer (or their respective designees) before Transacting. 2. Open Trading Window: The insider trading policy establishes that Covered Persons are only permitted to Transact in Covered Securities when no blackout period is in effect (i.e., during the period beginning on second full trading day following the date FIHL’s financial results are publicly disclosed and the related SEC filing is made and ending at the close of the market two weeks before the end of each fiscal quarter). However, even during a trading window, (i) a Covered Person who is in possession of any material non-public information should not trade in Covered Securities until the information has been made publicly available or is no longer material; and (ii) all Covered Persons must refrain from Transacting without first pre-clearing all Transactions in Covered Securities. Corporate Governance 15

3. No Tipping: No Covered Person who knows of any material non-public information about FIHL may communicate that information to any other person, including family members and friends, or otherwise disclose such information without FIHL’s authorization. 4. Prohibited Transactions: Covered Persons and entities over which such Covered Person exercises control are prohibited from engaging in the following transactions in Covered Securities unless advance approval is obtained from Fidelis Legal and Compliance: (i) Short-term trading – Associates who purchase Company securities may not sell any Company securities of the same class for at least six months after the purchase; (ii) Short Sales – Covered Persons may not sell Company securities short; (iii) Options trading – Covered Persons may not buy or sell puts or calls or other derivative securities on Company Securities; (iv) Trading on margin or pledging – Covered Persons may not hold Company securities in a margin account or pledge Company securities as collateral for a loan; and (v) Hedging – Covered Persons may not enter into hedging or monetization transactions or similar arrangements with respect to Company securities. We are committed to maintaining the highest standards of ethical conduct and have implemented the insider trading policy and procedures to ensure compliance with applicable securities laws and to protect the interests of our shareholders. Board Leadership Structure Our Board is divided into three classes, which are designated as Class I, Class II and Class III. The term for each Class II director expires at this year’s Annual General Meeting to be held on May 6, 2025; the term for each Class III director will expire at the Annual General Meeting in 2026; and the term for each Class I director will expire at the Annual General Meeting in 2027. At each annual general meeting of the Company, the successors of the class of directors whose term expires at that meeting will be elected for a term expiring at the annual general meeting to be held in the third year following the year of their election. Four Class II directors are to be elected at the annual general meeting to serve until the Company’s Annual General Meeting in 2028. All of the nominees are currently directors. Our Nominating and Corporate Governance Committee recommended all of the nominees to our Board for election at the meeting and all nominees have consented to serve on our Board. We do not expect that any of the nominees will become unavailable for election as a director, but if any nominee should become unavailable prior to the Annual General Meeting, proxy cards authorizing the proxy holder to vote for the nominees will instead be voted for substitute nominees recommended by our Board, unless the Board chooses to reduce the number of directors serving on the Board pursuant to the Amended and Restated Bye-laws. Our Board has reviewed its classified board structure and believes that this structure provides greater stability and continuity in the Board’s membership and in the direction and guidance that it provides to the Company’s management. As compared to an annual election process, this approach promotes a long-term perspective in relation to our strategic objectives and is beneficial to our CEO and executive management in establishing the Company’s short and long-term priorities. The classified board structure also ensures that at any given time, a majority of the directors serving on the Board will have substantial knowledge of the Company and its business, competitive environment, risks, culture and strategic goals. We believe directors who have experience with the Company are better positioned to make decisions that are best for the Company and its shareholders, particularly given the complexity of the specialty insurance industry. In addition, three-year terms assist in recruiting highly qualified directors who are willing to commit the time and resources to develop a deep understanding of the Company and its business and encourage a longer-term view. After carefully considering the arguments for and against a classified board structure, we believe that a classified election process is in the best interests of the Company and our shareholders at this time. As noted in our final prospectus filed pursuant to Rule 424(b)(4) (Registration No. 333-279562) with the SEC on May 23, 2024, available electronically at www.sec.gov, the classified Board will be in place until the Annual General Meeting in 2030, following which all of the directors shall be one class.

Corporate Governance 18

Board and Committee Performance Evaluations The Board believes that a regular and formal process of evaluation improves the performance of the Board as a whole, the committees and individual directors. A survey is sent annually to all directors inviting comments and suggestions on areas for improving the effectiveness of the Board and its committees. The results of this survey are reviewed by the Nominating and Corporate Governance Committee, which makes recommendations to the Board as required. The chairperson of our Nominating and Corporate Governance Committee also holds private interviews with each director annually to discuss the operations of our Board and its committees, and to provide any feedback on the individual director’s contributions.

The Reinsurance segment benefits from quota share, aggregate, stop loss and excess of loss retrocessional cover, catastrophe bond cover and industry loss warranties, which helps to minimize the potential net losses in the business written. We believe our strategy of pursuing closely controlled aggregates and focusing on residential portfolios in the Reinsurance segment helps keep volatility lower than a typical catastrophe book.
