The selling shareholders named under the caption “Principal and Selling Shareholders” below (the “Selling Shareholders”) are offering 9,000,000 common shares, par value $0.01 per share, of Fidelis Insurance Holdings Limited (the “Common Shares”). We will not receive any proceeds from the sale of the Common Shares sold by the Selling Shareholders in this offering.

Investing in our Common Shares involves risks. See “Risk Factors” beginning on page 27. Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus.

TABLE OF CONTENTS

i

ABOUT THIS PROSPECTUS

We and the Selling Shareholders have not authorized anyone to provide any information different from that contained in this prospectus or in any free writing prospectuses prepared by us or on our behalf or to which we have referred prospective investors. We and the Selling Shareholders take no responsibility for, and can provide no assurance as to the reliability of, any other information that others may give prospective investors. This prospectus is an offer to sell only the Common Shares offered hereby, but only under circumstances and in jurisdictions where it is lawful to do so. The information contained in this prospectus is accurate only at the date on the front cover of this prospectus, regardless of the time of delivery of this prospectus or any sale of our Common Shares.

We further note that the representations, warranties and covenants made by us in any agreement that is filed as an exhibit to the registration statement of which this prospectus is a part were made solely for the benefit of the parties to such agreement, including, in some cases, for the purpose of allocating risk among the parties to such agreement, and should not be deemed to be a representation, warranty or covenant made to prospective investors or for the benefit of prospective investors. Moreover, such representations, warranties or covenants were accurate only at the date they were made. Accordingly, such representations, warranties and covenants should not be relied on as accurately representing the current state of our affairs.

Certain Defined Terms

Certain abbreviations and definitions of certain insurance, reinsurance, financial and other terms used in this prospectus are defined in our Annual Report on Form 20-F for the year ended December 31, 2023, as filed with the SEC on March 15, 2024 incorporated by reference in this prospectus (the “2023 Annual Report”).

Exchange Control

The permission of the Bermuda Monetary Authority (the “BMA”) is required, under the provisions of the Exchange Control Act 1972 of Bermuda and related regulations, for all issuances and transfers of shares (which includes the Common Shares) of Bermuda companies to and/or from a non-resident of Bermuda for exchange control purposes, other than in cases where the BMA has granted a general permission. The BMA, in its notice to the public dated June 1, 2005, has granted a general permission for the issue and subsequent transfer of any securities of a Bermuda company from and/or to a non-resident of Bermuda for exchange control purposes for so long as any “Equity Securities” of the company (which would include the Common Shares) are listed on an “Appointed Stock Exchange” (which would include the NYSE). In granting the general permission, the BMA accepts no responsibility for our financial soundness or the correctness of any of the statements made or opinions expressed in this prospectus.

Service of Process and Enforcement of Civil Liabilities

We are a Bermuda exempted company. As a result, the rights of holders of our Common Shares will be governed by Bermuda law and our memorandum of association and the Amended and Restated Bye-Laws. The rights of shareholders under Bermuda law may differ from the rights of shareholders of companies incorporated in other jurisdictions. See “Comparison of Shareholder Rights.” Some of our directors and officers are not residents of the United States, and a substantial portion of our assets are located outside the United States. As a result, it may be difficult for investors to effect service of process on those persons in the United States or to enforce in the United States judgments obtained in U.S. courts against us or those persons based on the civil liability provisions of the U.S. securities laws. It is doubtful whether courts in Bermuda will enforce judgments obtained in other jurisdictions, including the United States, against us or our directors or officers under the securities laws of those jurisdictions or entertain actions in Bermuda against us or our directors or officers under the securities laws of other jurisdictions.

Investors Outside the United States

Neither we nor any of the Selling Shareholders have done anything that would permit the possession or distribution of this prospectus in any jurisdiction where action for that purpose is required, other than in the United States. Persons outside the United States who come into possession of this prospectus must inform themselves about, and observe any restrictions relating to, the offering of our Common Shares and the distribution of this prospectus outside of the United States.

REGISTERED TRADEMARKS AND TRADEMARK APPLICATIONS

We own or have rights to use trademarks, service marks or trade names that we use in connection with the operation of our business. Other trademarks, service marks and trade names appearing in this prospectus are the property of their respective owners. Solely for convenience, the trademarks, service marks, trade names and copyrights referred to in this prospectus are listed without the ^©, ^® and ^™ symbols, but we will assert, to the fullest extent under applicable law, our rights or the rights of the applicable licensors to these trademarks, service marks, trade names and copyrights.

MARKET AND INDUSTRY DATA AND FORECASTS

Certain market, peer and industry data and forecasts included in this prospectus were obtained from independent market research, industry publications and surveys, governmental agencies and publicly available information, including information from our peer group. Industry surveys, publications and forecasts generally state that the information contained therein has been obtained from sources believed to be reliable, but that the accuracy and completeness of such information is not guaranteed. We have not independently verified any of the data from third-party sources, nor have we ascertained the underlying assumptions relied upon therein. Similarly, independent market research and industry forecasts, which we believe to be reliable based upon our management’s knowledge of the industry, have not been independently verified. Our peer group includes Beazley (“BEZ”), Lancashire (“LRE”), Conduit (“CRE”), Hamilton (“HG”), Everest (“EG”), Axis (“AXS”), Berkley (“WRB”) and Markel (“MKL”). The calculations of our peers’ GPW excludes BEZ for 2023, CRE from 2018 to 2020 and 2023, LRE for 2023 and HG for 2018. The average NPE of our peers for 2018 to 2023 excludes BEZ and LRE for 2023, CRE from 2018 to 2020 and 2023 and HG for 2018. Our peers’ average loss ratios and combined ratios for 2021 and 2022 are calculated from a peer group including BEZ, LRE, CRE, HG, EG, AXS, WRB and MKL. Our peer average loss ratios and combined ratios for 2023 and the three months ended March 31, 2024, are calculated from a peer group consisting of HG, EG, AXS, WRB and MKL. BEZ, LRE and CRE are excluded from the calculations of our peer average loss ratios and combined ratios for 2023 and the three months ended March 31, 2024 as combined ratios are no longer reported on a like for like basis as compared to previous years following the adoption of IFRS 17. CRE, BEZ and LRE are excluded in 2023 from the calculations of our peers’ average combined ratios for 2018 to 2023, as their combined ratios are no longer reported on a like for like basis as compared to previous years following the adoption of IFRS 17. CRE is also excluded from 2018 to 2020 and HG for 2018. For fiscal years prior to 2022, HG financial information is calculated using a fiscal year ending on November 30.

While we are not aware of any material misstatements regarding the market, peer or industry data presented herein, our estimates involve risks and uncertainties and are subject to change based on various factors, including those discussed under the heading “Risk Factors” and Item 3. Key Information—D. Risk Factors of the 2023 Annual Report.

References to “The Fidelis Partnership” (formerly known as “Fidelis MGU”) or “TFP” refer to TFP HoldCo and its consolidated subsidiaries. Unless otherwise stated or the context otherwise requires, all information in this prospectus reflects the completion of this offering. References to “segment(s)” and “pillar(s)” shall have the same meaning as used herein and shall be used interchangeably to refer to each of the three pillars or segments of our business, Specialty, Bespoke and Reinsurance.

The financial information included herein has been derived from the financial statements and accounting records of Fidelis Insurance Group and has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”). Amounts in this prospectus and the financial statements included in this prospectus are presented in U.S. dollars rounded to the nearest million, unless otherwise noted. Certain amounts presented in tables are subject to rounding adjustments and, as a result, the totals in such tables may not sum.

The financial information included herein contains the following measures, which we use to assess the financial performance of our business:

Premiums Written

Premiums written are recorded on inception of the policy. Premiums written include estimates based on information received from insureds, brokers and cedants, and any subsequent differences arising on such estimates are recorded as premiums written in the period in which they are determined.

Earned and Unearned Premiums

Premiums written are earned on a basis consistent with risks covered over the period the coverage is provided. NPW, when earned, are referred to herein as net premiums earned (“NPE”).

The portion of the premiums written applicable to the unexpired terms of the underlying contracts and policies are recorded as unearned premium (“UPR”).

Non-U.S. GAAP Financial Measures

Our financial statements included in this prospectus have been prepared in accordance with U.S. GAAP. We have included certain non-U.S. GAAP financial measures in this prospectus, as further described below, that may not be directly comparable to other similarly titled measures used by other companies and therefore may not be comparable among companies. For purposes of Regulation G and Section 10(e) of Regulation S-K, a non-U.S. GAAP financial measure is a numerical measure of a company’s historical or future financial performance, financial position or cash flows that excludes amounts, or is subject to adjustments that have the effect of excluding amounts, that are included in the most directly comparable measure calculated and presented in accordance with U.S. GAAP in the statements of operations, balance sheets, or statement of cash flows of the company; or includes amounts, or is subject to adjustments that have the effect of including amounts, that are excluded from the most directly comparable measure so calculated and presented. Pursuant to the requirements of Regulation G and Section 10(e) of Regulation S-K, we have provided reconciliations of non-U.S. GAAP financial measures to the most directly comparable U.S. GAAP financial measures. These non-U.S. GAAP measures are provided because our management uses these financial measures in monitoring and evaluating our ongoing results and trends.

This prospectus contains “non-U.S. GAAP financial measures,” including accident year loss ratio excluding catastrophes, large losses and prior year reserve movements (also known as the “attritional loss ratio” (in total and for each operating segment)), operating net income, operating earnings per diluted Common Share

3

(“Operating EPS”), and operating return on average common equity (“Operating ROAE”), which are financial measures that are not required by, or presented in accordance with U.S. GAAP.

We believe that, in addition to our results determined in accordance with U.S. GAAP (that include performance measures such as ratio of losses and loss adjustment expenses to NPE (“loss ratio”), underwriting ratio, TFP commissions ratio (formerly, Fidelis MGU commissions ratio), policy acquisition expenses ratio, general and administrative expenses ratio, combined ratio, net investment return, total investment return, net investment return percentage, total investment return percentage and return on average common equity (“ROAE”)), certain non-U.S. GAAP measures, including accident year loss ratio excluding catastrophes, large losses and prior year reserve movements (also known as the “attritional loss ratio” (in total and for each operating segment)), operating net income, Operating EPS, and Operating ROAE are useful in evaluating our business and the underlying trends that are affecting our performance. Such non-U.S. GAAP measures are primary indicators that our management uses internally to conduct and measure its business and evaluate the performance of its consolidated operations. Our management believes these non-U.S. GAAP financial measures are useful as they provide meaningful analysis of the performance of the business. These non-U.S. GAAP financial measures are used in addition to and in conjunction with results presented in accordance with U.S. GAAP. These non-U.S. GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our U.S. GAAP results and, where applicable, the accompanying reconciliations to corresponding U.S. GAAP financial measures, provide a more complete understanding of factors and trends affecting our business. A material limitation associated with these non-U.S. GAAP measures compared to the U.S. GAAP measures is that they may not be comparable to other companies with similarly titled items that present related measures differently. The non-U.S. GAAP measures should be considered as a supplement to, and not as a substitute for or superior to, the corresponding measures calculated in accordance with U.S. GAAP.

See “Summary—Summary Financial and Operating Data—Reconciliation of Operating EPS” together with Item 5. Operating and Financial Review and Prospects—A. Operating Results—Performance Measures and Non-GAAP Financial Measures of the 2023 Annual Report and Management’s Discussion and Analysis of Financial Condition and Results of Operations—Performance Measures and Non-GAAP Financial Measures of Exhibit 99.2 of our Current Report on 6-K related to our quarterly financial results for the three months ended March 31, 2024, as filed with the SEC on May 9, 2024, incorporated by reference in this prospectus (the “Q1 2024 Quarterly Report”) for an explanation and reconciliation of these non-U.S. GAAP financial measures to the most directly comparable financial measures stated in accordance with U.S. GAAP.

RISK FACTORS

Investing in the Common Shares involves risks. Prospective investors should carefully consider the risks described below and those discussed in Item 3. Key Information—D. Risk Factors of the 2023 Annual Report which is incorporated by reference in this prospectus, our other SEC filings incorporated by reference in this prospectus as well as other information contained in this prospectus before making an investment decision. The risks described below are not the only ones we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also materially and adversely affect us in the future. Any of the following risks could materially adversely affect our business, prospects, financial condition, results of operations or cash flows and could impact any forward-looking statements. See “Cautionary Note Regarding Forward-Looking Statements.” In such case, the trading price of the Common Shares may decline and investors may lose all or part of their original investments.

Risks Relating to the Common Shares and this Offering

The price per Common Share may change significantly following this offering, and investors may not be able to resell their Common Shares at or above the price they paid or at all, and investors could lose all or part of their investment as a result.

The Selling Shareholders and the underwriters will negotiate the offering price of the Common Shares to be offered pursuant to this prospectus. Investors may not be able to resell their Common Shares at or above the offering price due to a number of factors, such as those listed in this “Risk Factors” section, and Item 3. Key Information—D. Risk Factors of the 2023 Annual Report and the following:

27

Furthermore, the stock market has experienced and is likely to continue to experience extreme volatility and significant price and volume fluctuations that, in some cases, have been and may be unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the market price of our Common Shares, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our Common Shares continues to be low. The Common Shares began trading on the NYSE on June 28, 2023 and as such, are newly listed, have a limited public float and a short trading history to date.

Following periods of market volatility, shareholders in U.S. listed groups from time to time may institute securities class action litigation. If Fidelis Insurance Group were to become involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

If securities or industry analysts do not publish research or reports about Fidelis Insurance Group’s business or if they downgrade the Common Shares or the (re)insurance industry generally, or if there is any fluctuation in Fidelis Insurance Group’s ratings, the price of the Common Shares and trading volume could decline.

The trading market for our Common Shares relies in part on the research and reports that industry or financial analysts publish about Fidelis Insurance Group and its business. Fidelis Insurance Group does not control these analysts. Furthermore, if one or more of the analysts who do cover Fidelis Insurance Group downgrade the Common Shares or the (re)insurance industry, or the stock of any of Fidelis Insurance Group’s competitors, or publish inaccurate or unfavorable research about Fidelis Insurance Group’s business, the price of Common Shares could decline. If one or more of these analysts stop covering Fidelis Insurance Group or fail to publish reports on it regularly, we could lose visibility in the market, which in turn could cause the price or trading volume of the Common Shares to decline.

Additionally, any fluctuation in Fidelis Insurance Group’s ratings may impact Fidelis Insurance Group’s ability to access debt markets in the future or increase the cost of future debt, which could have a material adverse effect on Fidelis Insurance Group’s operations and financial condition, which in return may adversely affect the trading price of the Common Shares.

If FIHL, the Selling Shareholders or other existing shareholders sell additional Common Shares after this offering or are perceived by the public markets as intending to sell additional Common Shares, the market price of the Common Shares could decline.

The sale of Common Shares in the public market by the Company in a primary offering or its existing shareholders in a secondary offering, including sales pursuant to this prospectus, or the perception that such sales could occur, could harm the prevailing market price of the Common Shares. Such sales, the perception that the holders of a large number of Common Shares intend to sell Common Shares or the possibility that such sales may occur, also might make it more difficult for FIHL to sell Common Shares in the future at a time and at a

28

price that it deems appropriate. Sales or resales of a substantial number of Common Shares in the public market could occur at any time and may cause the market price of our securities to drop significantly, even if our business is doing well. We are unable to predict the effect that such sales may have on the prevailing market price of the Common Shares.

All of our Common Shares currently outstanding, including the Common Shares sold in this offering, are freely tradable without restriction or further registration under the Securities Act so long as they are held by persons other than our “affiliates,” as that term is defined under Rule 144 of the Securities Act, and certain executives of Fidelis Insurance Group and TFP. Certain existing holders of our Common Shares, who are also our “affiliates” as that term is defined under Rule 144 of the Securities Act, have registration rights, pursuant to the Registration Rights Agreement, subject to some conditions, to require us to file registration statements covering the sale of their Common Shares or to include their Common Shares in registration statements that we may file for ourselves or other shareholders in the future. In the event that we register the Common Shares for the holders of registration rights, they can be freely sold in the public market upon issuance. See “Shares Eligible for Future Sales,” as well as Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions and Item 19. Exhibits—Exhibit 2.1 Description of Securities of the 2023 Annual Report.

The Common Shares being offered pursuant to this prospectus by the Selling Shareholders represent approximately 7.699% of FIHL’s outstanding Common Shares as of May 17, 2024. As restrictions on resale end and certain lock-up agreements entered into in relation to the initial public offering of Common Shares expire, the volatility of the market price of the Common Shares could increase or a significant reduction of the market price of the Common Shares could occur if the holders sell such Common Shares or are perceived by the market as intending to sell such Common Shares. These factors could also make it more difficult for us to raise additional funds through offerings of Common Shares or other securities.

A decline in the price of our Common Shares may impede our ability to raise capital through the issuance of additional Common Shares or other equity securities. See “Shares Eligible for Future Sales” and Item 19. Exhibits—Exhibit 2.1 Description of Securities of the 2023 Annual Report.

Future offerings of debt or equity securities which would rank senior to the Common Shares may adversely affect the market price of the Common Shares.

If, in the future, FIHL decides to issue debt or equity securities that rank senior to the Common Shares, it is likely that such securities will be governed by an indenture or other instrument containing covenants restricting Fidelis Insurance Group’s operating flexibility. Additionally, any convertible or exchangeable securities that FIHL may issue in the future may have rights, preferences and privileges more favorable than those of the Common Shares and may result in dilution to owners of the Common Shares. FIHL and, indirectly, its shareholders, will bear the cost of issuing and servicing such securities.

Fidelis Insurance Group takes a proactive approach to capital management based on opportunities presented and sought out. Fidelis Insurance Group may therefore seek to raise additional funds through opportunistic financings in order to take advantage of market conditions and opportunities to write more business. FIHL may raise such funds by issuing further securities including equity and debt, whether senior or subordinated in ranking.

Because the decision to issue debt or equity securities in any future offering will depend on market conditions and other factors beyond Fidelis Insurance Group’s control, Fidelis Insurance Group cannot predict or estimate the amount, timing or nature of such future offerings. Thus, holders of Common Shares will bear the risk of future offerings reducing the market price of the Common Shares and diluting the value of their holdings in FIHL.

29

We are currently listed on the NYSE. If we are unable to maintain listing of the Common Shares on the NYSE or any stock exchange, our stock price could be adversely affected and the liquidity of the Common Shares and our ability to obtain financing could be impaired and it may be more difficult for our shareholders to sell their Common Shares.

Although our Common Shares are currently listed on the NYSE, we may not be able to continue to meet the NYSE’s minimum listing requirements or those of any other national securities exchange. The listing rules of the NYSE require listed issuers to comply with certain standards in order to remain listed on its exchange. If, for any reason, we should fail to maintain compliance with these listing standards and the NYSE should delist the Common Shares from trading on its exchange and we are unable to obtain listing on another national securities exchange, a reduction in some or all of the following may occur, each of which could have a material adverse effect on our shareholders:

30

USE OF PROCEEDS

The Selling Shareholders will receive all of the net proceeds from the sale of the Common Shares offered pursuant to this prospectus. We are not selling any Common Shares under this prospectus and will not receive any proceeds from the sale of Common Shares, including from any exercise by the underwriters of their option to purchase additional Common Shares. The Selling Shareholders participating in this offering are described under the section titled “Principal and Selling Shareholders.”

31

DIVIDEND POLICY

The declaration, amount and payment of any dividends on our Common Shares will be at the sole discretion of the Board, which may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our shareholders or by our subsidiaries to us, including restrictions under any of our then outstanding indebtedness, and such other factors as the Board may deem relevant. If we elect to pay dividends in the future, we may reduce or discontinue entirely the payment of such dividends at any time. At the Board’s discretion, we declare and pay a dividend quarterly on the Series A Preference Securities, which rank senior to and have priority over the Common Shares. The Board approved a dividend of $225.00 per Series A Preference Security with a record date of February 15, 2024, paid on March 15, 2024. For a more detailed description of the Series A Preference Securities see Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions of the 2023 Annual Report.

On February 29, 2024, we announced (i) the adoption of a dividend program for the Common Shares under which FIHL intends to pay a quarterly cash dividend and (ii) an initial dividend to be paid pursuant to the dividend program, in an amount of $0.10 per Common Share, which was paid on March 29, 2024 to holders of Common Shares of record on March 15, 2024.

On May 8, 2024, we announced that the Board of Directors approved a dividend of $0.10 per Common Share, payable on June 28, 2024 to holders of Common Shares of record on June 14, 2024.

FIHL is a holding company and, as such, has no substantial operations of its own. FIHL does not expect to have any significant operations or assets other than ownership of the shares of operating subsidiaries. Dividends and other permitted distributions and loans from operating subsidiaries are expected to be the sole source of funds to meet ongoing cash requirements, including payment of dividends to shareholders holding Series A Preference Securities, debt service payments and other expenses and to pay dividends, if any, to holders of the Common Shares. Fidelis Insurance Group’s operating subsidiaries are subject to significant regulatory restrictions limiting their ability to declare and pay dividends and make loans to other Group companies. FIHL’s ability to pay dividends on Common Shares is also dependent on the availability of distributable reserves. In addition, FIHL’s ability to pay dividends is subject to the restrictive covenants of our existing and outstanding indebtedness and may be limited by covenants of any future indebtedness we incur.

32

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This prospectus contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and are intended to qualify for the safe harbor for liability established by the Private Securities Litigation Reform Act of 1995. These forward-looking statements are intended to enhance the reader’s ability to assess our future financial and business performance. These statements are based on the beliefs and assumptions of our management, and are subject to known and unknown risks and uncertainties. Generally, statements that are not about historical facts, including statements concerning our possible or assumed future actions or results of operations, are forward-looking statements. Forward-looking statements include, but are not limited to, statements that represent our beliefs, expectations or estimates concerning future operations, strategies, financial results or performance, financings, investments, acquisitions, expenditures or other developments and anticipated trends and competition in the markets in which we operate.

Forward-looking statements can also be identified by the use of forward-looking terminology such as “may,” “believes,” “intends,” “anticipates,” “plans,” “estimates,” “targets,” “potential,” “will,” “can have,” “likely,” “continue,” “expects,” “should,” “could” or similar expressions. Forward-looking statements are not guarantees of performance and we caution prospective investors not to rely on them. We qualify all of our forward-looking statements by these cautionary statements, because these forward-looking statements are based on estimates and assumptions that are subject to significant business, economic and competitive uncertainties, many of which are beyond our control or are subject to change. Actual results or other outcomes could differ materially from those expressed or implied in our forward-looking statements, as a result of several factors, including the following:

33

Consequently, such forward-looking statements should be regarded solely as our current plans, estimates or belief as of the date of this prospectus. We do not intend, and do not undertake, any obligation to update any forward-looking statements to reflect future events or circumstances after the date of this prospectus. Given such limitations, prospective investors should not rely on these forward-looking statements in deciding whether to invest in our Common Shares.

34

In addition, statements that contain “we believe” and similar statements reflect our beliefs and opinions on the relevant subject. These statements are based on information available to us as of the date of this prospectus. While we believe that this information provides a reasonable basis for these statements, this information may be limited or incomplete. These statements are inherently uncertain, and investors are cautioned not to unduly rely on these statements.

Prospective investors should review carefully the section captioned “Risk Factors” in this prospectus and the documents incorporated by reference for a more complete discussion of risks and uncertainties relating to an investment in our Common Shares.

BUSINESS

Our History; Then to Now

Fidelis Insurance Group is a global specialty insurer, leveraging strategic partnerships to offer innovative and tailored insurance solutions. We have a highly diversified portfolio focused on three segments: Specialty, Bespoke, and Reinsurance, which we believe allows us to take advantage of the opportunities presented by evolving (re)insurance markets, proactively shift our business mix, and produce superior underwriting returns across market cycles. Headquartered in Bermuda, with subsidiaries located in Ireland and the UK, Fidelis Insurance Group operating companies have a financial strength rating of A from AM Best, A- from S&P and A3 from Moody’s, as of May 17, 2024.

FIHL was formed under the principles of a focused, process-driven and disciplined underwriting and risk selection, strong client and broker relationships and nimble capital deployment. Fidelis completed its initial funding and began underwriting business in June 2015 under the direction of an innovative and experienced management team.

Since then, FIHL has assembled a diversified global book of (re)insurance business and achieved scale with GPW of $3.6 billion and NPE of $1.8 billion for the year ended December 31, 2023. Between 2018 and 2023, our GPW and NPE have grown at compounded annual rates of 38.9% and 44.5%, respectively, and we have delivered an average loss ratio of 45.1% and an average combined ratio of 85.8% over the same period.

The Separation Transactions

On January 3, 2023, the Separation Transactions were completed and two distinct holding companies and businesses were created: FIHL and TFP HoldCo. FIHL, the parent holding company for Fidelis Insurance Group, owns the insurance operating subsidiaries of Fidelis, comprised of Fidelis Insurance Bermuda Limited (“FIBL”), Fidelis Underwriting Limited (“FUL”) and Fidelis Insurance Ireland DAC (“FIID”). Fidelis Insurance Group also has its own service company, FIHL (UK) Services Limited, with a branch in Ireland (“FIHL (UK) Services”).

TFP HoldCo is the parent holding company for the managing general underwriting platform (“TFP”) that carries on origination and underwriting activities on behalf of Fidelis Insurance Group. TFP HoldCo’s principal operating subsidiaries are Pine Walk Capital Limited (“Pine Walk Capital”), Pine Walk Europe SRL (“Pine Walk Europe”) and Shelf Opco Bermuda Limited (“TFP Bermuda”). The underwriting activities of each of the licensed insurance carriers of Fidelis Insurance Group (FIBL, FUL and FIID) are outsourced to the corresponding operating subsidiaries of TFP on a jurisdictional basis (TFP Bermuda, Pine Walk Capital and Pine Walk Europe, respectively). Each of the operating subsidiaries of TFP has delegated underwriting authority to source and bind contracts for and on behalf of each of FIBL, FUL and FIID, respectively. See Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions of the 2023 Annual Report.

On December 20, 2022, FIHL and TFP HoldCo entered into a rolling 10-year framework agreement (the “Framework Agreement”) that governs the ongoing relationship between the two groups of companies (see “Summary—Our Corporate Structure” for additional details).

Following the consummation of the Separation Transactions, FIHL can access the underwriting expertise of TFP while enabling TFP to attract and retain highly sophisticated underwriting talent by allowing them to focus their time and expertise on underwriting activities. We believe that the Separation Transactions and the Framework Agreement have structural benefits for both groups of companies, including increased flexibility to quickly respond to evolving insurance and reinsurance market conditions and to help sustain our strong underwriting results through access to top talent. Our objective following the completion of the Separation Transactions remains to further solidify Fidelis Insurance Group’s position as a leading specialty, bespoke and reinsurance underwriter.

Our Company

Fidelis Insurance Group is a global specialty insurer focused on three segments: Specialty, Bespoke and Reinsurance. The Specialty and Bespoke segments together accounted for 82.8% of total GPW in 2023.

Fidelis Insurance Group is led by Mr. Daniel Burrows who has more than 35 years of experience in the insurance industry and is supported by a highly experienced management team that manages the operations of Fidelis Insurance Group based on our founding principles.

We have an exclusive right of first access to TFP’s underwriting business via the Framework Agreement where FIHL collaborates closely with TFP to match what we believe are superior priced risks with efficient sources of capital to produce attractive returns for shareholders. Through this operating model, we believe we are well positioned to be nimble, thoughtful, and efficient decision-makers, and we believe that we are able to respond quickly to an ever-changing world and a constantly evolving marketplace. Furthermore, FIHL’s strong capital position provides flexibility to underwrite attractive opportunities and make strategic capital allocation decisions.

We focus on nimble underwriting designed to capitalize on current market trends and dislocations as well as emerging risk solutions. The team of underwriters at TFP continues to maintain the processes and technology that have been key to Fidelis Insurance Group’s historical success at ensuring its underwriting efforts capture recent market developments. We believe this close coordination reduces the likelihood of siloed underwriting and gives us a competitive advantage in our underwriting, risk assessment and ability to offer as many products as possible to clients. A crucial and distinguishing part of those processes is the daily UMCC. Members of Fidelis Insurance Group attend and participate in the UMCC on a daily basis, together with TFP practice leads and key members of TFP senior management (including risk modeling, actuarial, legal, compliance, contract wordings and claims representatives) to provide live market insights and multiple perspectives to allow underwriters to quickly assess emerging opportunities, achieve strong underwriting and cross-sell across our product range. See “—Our Competitive Strengths” below for further detail.

Our scale and access to the highly selective underwriting capabilities of TFP via our strategic relationship allows us to capitalize on current insurance market trends and continue focusing on delivering growth coupled with strong underwriting results.

Since we began underwriting business in 2015, Fidelis Insurance Group has grown in scale in specialty and bespoke insurance and property reinsurance markets while delivering robust results. Our GPW grew from $0.7 billion for the year ended December 31, 2018 to $3.6 billion for the year ended December 31, 2023, a compound annual growth rate of 38.9%, compared to our peers’ average compounded annual growth rate for GPW of 22.1% for the same period. During that same period, we delivered an average combined ratio of 85.8%, compared to our peers’ average combined ratio of 100.2%. Our average loss ratio was 45.1% during that same period.

Our NPE grew from $0.3 billion for the year ended December 31, 2018 to $1.8 billion for the year ended December 31, 2023, a compound annual growth rate of 44.5%, compared to our peers’ average of 31.9%. Our GPW and NPE continued to grow to $1,514.3 million and $488.0 million, respectively, for the three months ended March 31, 2024, compared to $1,245.3 million and $386.0 million, respectively, for the three months ended March 31, 2023.

Our loss and combined ratio for the three months ended March 31, 2024 were 37.4% and 85.8%, respectively, compared to our peers’ average loss and combined ratios of 60.0% and 91.0%, respectively. Our loss ratio was 60.1%, 55.3% and 38.1% in 2021, 2022 and 2023, respectively, compared to our peers’ average loss ratios of 64.7%, 62.7% and 61.8%, respectively. Over the same period, our combined ratio was 93.0%, 91.9% and 82.1%, compared to our peers’ average combined ratios of 100.1%, 96.1% and 93.8%. Our peer group includes Beazley (“BEZ”), Lancashire (“LRE”), Conduit (“CRE”), Hamilton (“HG”), Everest (“EG”), Axis

37

(“AXS”), Berkley (“WRB”) and Markel (“MKL”). For information on how peer group data is included or excluded, see “About this Prospectus—Market and Industry Data and Forecasts.”

Fidelis Insurance Group is subject to varying degrees of regulation and supervision in the jurisdictions in which it operates. In particular, the businesses of our three insurance operating subsidiaries, FIBL, FUL and FIID, are authorized by, and subject to insurance laws and regulations that are administered and enforced by, a number of different governmental and non-governmental self-regulatory authorities and associations in each of their respective jurisdictions and internationally. For a summary of the regulatory environment of our insurance operating subsidiaries, primarily in their respective jurisdictions of Bermuda, U.K. and Ireland, see Item 4. Information on the Company—B. Business Overview—Regulatory Matters of the 2023 Annual Report.

As of the date of this prospectus, Fidelis Insurance Group was assigned an “A” (Excellent) financial strength rating by A.M. Best, the third-highest of 13 rating levels, with a stable outlook on all entities. A.M. Best’s ratings range from “A+” to “D.” Each A.M. Best rating category from “A+” to “C” may be designated either an additional plus (+) or a minus (-) sign as a rating notch that reflects a gradation of financial strength within the rating category. Additionally, A.M. Best assigned a “BBB” long-term issuer credit rating to FIHL (with stable outlook), which indicates a good ability to meet ongoing senior financial obligations and a financial strength rating of “A” (Excellent) and the long-term issuer credit rating of “A” (Excellent) to each of FIBL, FUL and FIID (with stable outlook).

As of the date of this prospectus, Fidelis Insurance Group was assigned an “A-” financial strength rating by S&P Global Ratings (“S&P”), with a stable outlook, which indicates strong capacity to meet financial commitments but somewhat more susceptibility to the adverse effects of changes in circumstances and economic conditions than those in higher-rated categories. S&P’s ratings range from “AAA” to “D.” Each S&P rating category from “AA” to “CCC” may be modified by the addition of a plus (+) or minus (-) sign to show relative standing within the rating categories. Additionally, S&P has assigned a “BBB” long-term issuer rating to FIHL, which indicates adequate capacity to meet financial commitments but greater susceptibility to adverse economic conditions.

As of the date of this prospectus, Moody’s Investor Service (“Moody’s”) assigned a “Baa2” long-term issuer rating to FIHL and “A3” insurance financial strength ratings to FIBL, FUL and FIID. The outlook for FIHL is stable. Moody’s generic rating classifications range from “Aaa” to “C.” Each Moody’s generic rating classification from “Aa” to “Caa” may be modified to append numerical modifiers 1, 2, or 3 to show relative position within the rating categories. See Item 4. Information on the Company—B. Business Overview—Insurer Financial Strength Rating of the 2023 Annual Report for further discussion of ratings assigned to Fidelis Insurance Group’s insurance operating subsidiaries.

Strategic Relationship with TFP

We believe the insurance industry is evolving rapidly and is primed for further value chain disaggregation which will allow specialist underwriters to benefit from access to clients and risks and to provide access to alternate forms of capital.

Following the consummation of the Separation Transactions, TFP HoldCo became a minority investor in FIHL (holding 9.9% of the Common Shares) and entered into the Framework Agreement with FIHL to build a long-term agency relationship that provides strong economic and strategic alignment between the two groups of companies. Pursuant to the Framework Agreement, TFP manages underwriting, origination, certain outwards reinsurance placements, actuarial and claims services with close review and oversight from Fidelis Insurance Group to ensure adherence with the agreed upon annual plans, which set out our underwriting parameters and risk tolerances in respect of our three segment underwriting strategy on a gross / net basis for each annual period. For more details on our outsourcing arrangements with TFP, see Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Framework Agreement of the 2023 Annual Report.

38

Pursuant to our outsourcing arrangements with TFP, we leverage their sophisticated underwriting technology and talent and will benefit from our shared history in underwriting principles, strategic visions, and managerial approaches. Our arrangement is governed by arm’s-length terms for origination and management consistent with industry commission levels, including market overrider commissions, and with a focus on aligning incentives for strong underwriting performance. Ceding commissions payable to TFP are charged for underwriting, claims and actuarial pricing services. Such ceding commissions are calculated based on NPW to ensure alignment on reinsurance purchasing. To avoid fee duplication, ceding commissions payable for open market business sourced by TFP are set at 11.5% and ceding commissions payable for business sourced by TFP via third-party managing general underwriters to whom underwriting authority has been sub-delegated by TFP are set at 3.0%. Business that continues to be sourced by subsidiary cells of Pine Walk Capital will continue to follow the fees and commissions set under those agreements (approximately 10%). Long-term objectives are further aligned by FIHL paying an ongoing portfolio management fee of 3.0% (the “Portfolio Management Fee”) to TFP and a 20.0% profit commission on Operating RoE (“Binder Operating RoE”) above a hurdle rate of 5.0% calculated on an aggregate basis for Fidelis Insurance Group. Binder Operating RoE is defined in the Framework Agreement as FIHL’s consolidated net underwriting margin (disregarding any business not underwritten by TFP following the date of the Framework Agreement and the effect of any FIHL Procured Outwards Reinsurance, as defined in the Framework Agreement) plus all overriders retained by Fidelis Insurance Group (disregarding the effect of any FIHL Procured Outwards Reinsurance), minus an Administrative Expenses Allowance (defined in the Framework Agreement as a sum equating to 2.3% of net premiums written), minus the proportion of FIHL’s costs of financing its debt and preference securities included in FIHL’s total capital that is deemed to be allocated to TFP, minus the total accumulated ceding commission that is payable by Fidelis Insurance Group to TFP, minus the Portfolio Management Fee relating to business underwritten by TFP, divided by the proportion of FIHL’s opening common shareholders’ equity adjusted for dividend and equity raises (as set out in year-end consolidated audited financial statements) that is deemed to be allocated to TFP. The calculation of such profit commission includes a deficit carry-forward mechanism for a maximum of three years in which the Binder Operating RoE is below zero. For a more detailed discussion of the fees and commissions payable by Fidelis Insurance Group in connection with its outsourced relationship with TFP, see Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Framework Agreement—Fees and Commissions of the 2023 Annual Report.

Our Commitment to Environmental, Social and Governance Matters

Fidelis Insurance Group is committed to working together with TFP to implement standards for environmental, social and governance (“ESG”) matters. We carried out a joint study on approximately $8.2 billion of premiums and 28,500 policies spanning between 2012 and 2021, which demonstrated that higher third-party ESG ratings were generally correlated with lower loss ratios. As such, we aim to embed ESG factors in our underwriting processes where appropriate, including through TFP’s existing underwriting restrictions. These underwriting restrictions include not directly insuring thermal coal (including dedicated infrastructure projects such as ports and railways), tar sand extraction, Arctic oil and gas exploration and drilling and fracking operations. Further, we do not provide cover to companies whose revenues from the above-mentioned activities account for more than 20% of their total revenues. TFP also uses policy language with the aim to minimize exposure to forced labor and modern slavery, in particular in the marine cargo line of business. Additionally, together with TFP, we are currently committed to transitioning our insurance portfolios to net-zero greenhouse gas emissions by 2050. To work towards this, to the extent possible, TFP are developing tools to measure the insurance-associated emissions of their insurance portfolios.

Furthermore, FIHL’s fixed income investment portfolio (which represents 98.6% of invested assets as of December 31, 2023) is managed in a manner that is consistent with Fidelis Insurance Group’s sustainability principles and ESG objectives. At December 31, 2023, 3.3% of Fidelis Insurance Group’s fixed income portfolio was invested in green, social and sustainable (“GSS”) bonds. The GSS Indices utilize the Bloomberg Global Aggregate Index, the Bloomberg Sustainable Finance Group’s GSS bond indicators and fields that show alignment with the International Capital Market Association Green Bond, Social Bond and Sustainability Bond Principles and

39

Guidelines. Furthermore, the investment portfolio includes restrictions against holding securities of issuers that have a ‘poor’ MSCI ESG rating (with a rating below ‘B’ or issuers that currently have a ‘red’ MSCI controversy flag). Securities of these issuers may only be held if Fidelis determines it is appropriate to do so after considering whether the investment manager has a positive forward-looking ESG view of the issuer. Fidelis Insurance Group has also adopted negative screens to work to limit exposure to certain industries and activities in its fixed income investment portfolio. These include screens against holding securities of any issuers involved in thermal coal, oil and gas (though an issuer may derive up to 20% of its annual revenues from oil and gas) or arms (certain types of arms are completely excluded, others such as firearm sales are permitted to comprise up to 10% of annual revenues), and restrictions against those that fail animal welfare and for-profit prisons screens. As a result of such negative screens, Fidelis was able to limit the fixed income portfolio’s direct exposure to the securities of companies deriving revenues from fossil fuels to seven companies, which at December 31, 2023 comprised 0.7% of Fidelis Insurance Group’s fixed income portfolio. Furthermore, currently Fidelis Insurance Group has no direct exposure in its investment portfolio to energy companies and its exposure to corporate securities identified as “utilities” comprised 1.1% of the fixed income portfolio at December 31, 2023.

Additionally, we have taken action in each year since 2018 to more than offset our operational carbon emissions and we are committed to continuing to do so going forward. We partner with relevant industry specialists to calculate our carbon emissions.

Diversity, equity and inclusion are integral to Fidelis Insurance Group. We pursue a diversity, equity and inclusion strategy that includes accountability, representation, advancement, culture, outreach and fostering a sense of belonging for all our employees. We employ targeted recruiting strategies to identify a wide range of qualified candidates and partner with external agencies to advertise vacancies with the goal of increasing the hiring of women and ethnically diverse employees. Where available, we monitor certain diversity, equity and inclusion statistics (gender, ethnicity, age, marital status, religion, caring responsibilities and disability, each as provided by candidates on a voluntary basis) both at the outreach/interview stage and for our employee population so that we can see progress with respect to the composition of our qualified candidate pools. Comparative data on diverse candidate sourcing available to us demonstrates a diversity mix of approximately 48% female identifying applicants, and approximately 70% of applicants identifying as people of a diverse ethnicity. During the period from March 2023 to February 2024, approximately 82% of open roles for which the Company recruited achieved a short list including diverse candidates.

Our Business; Overview

Our business comprises three segments: “Specialty,” “Bespoke” and “Reinsurance.” We believe our strategy and capabilities allow us to take advantage of the opportunities presented by evolving (re)insurance markets and to proactively shift our business mix across market cycles to generate strong returns. We have built a diverse portfolio of over 100 products within our 11 lines of business across our three segments, serving numerous industries, types of exposure, and geographies.

The Specialty segment comprises a portfolio of Aviation and Aerospace, Energy, Marine, Property, Property D&F business and Other Specialty risks.

The Bespoke segment is highly specialized in nature providing customized risk solutions for clients which includes Credit & Political Risk and Other Bespoke risk transfer opportunities.

The Reinsurance segment includes Property Reinsurance, Retrocession and Whole Account reinsurance.

Specialty

For the year ended December 31, 2023, the Specialty segment accounted for 62.6% of our GPW and 65.7% of our NPE with an underwriting ratio of 72.5% and a loss ratio of 48.5%. In 2023, the Specialty segment

40

generated $331.1 million in underwriting income. GPW in the Specialty segment grew from $44.1 million for the year ended December 31, 2018 to $2.2 billion for the year ended December 31, 2023, a compound annual growth rate of 119.4%. During the period from 2018 to 2023, our average underwriting ratio was 68.1%. For the three months ended March 31, 2024 our Specialty GPW grew to $1,034.0 million compared to $834.1 million for the three months ended March 31, 2023. Our Specialty segment from 2018 to 2023 accounted for 6.4%, 12.1%, 36.6%, 40.0%, 53.6%, and 62.6%, respectively, of our GPW. Property D&F accounted for 25%, Marine 19%, Aviation and Aerospace 10%, Energy 4%, Property 3% and Other Specialty 2% of our GPW for the twelve months ended March 31, 2024.

The Specialty segment comprises a portfolio of tailored risks across specialty business lines. “Hard” market conditions following years of compound rate increases across multiple business lines within the Specialty segment have provided opportunities for targeted growth and the ability to leverage leadership and scale. This, combined with long established relationships, has enabled Fidelis Insurance Group to build across specialty classes. Given the current market environment we have increasingly used our Specialty segment to deploy capital targeted to natural catastrophe exposure through the Property D&F line of business rather than through our Reinsurance segment. This allows a more selective approach to managing aggregate exposure. We further capitalized on market dislocations and associated rate increases in key classes such as Marine and Aviation and Aerospace to increase the amount of business written. Our Aviation and Aerospace, Property D&F and Marine businesses are among the leading franchise positions in the London market. The Specialty segment benefits from a program of reinsurance protections which are tailored across product lines. The program incorporates facultative covers as well as proportional and non-proportional treaties including aggregate, occurrence, per risk and parametric products such as cat bonds and industry loss warranties, which reduce the impact of frequency and severity claims, and protect capital.

Our Specialty segment provides us with access to more capital-efficient business and facilitates diversification of our exposures. In the Specialty segment, our underwriters work closely with TFP’s experts to develop collaborative relationships with brokers and clients and offer them the full suite of our existing products as well as working with them to innovate new product ideas. We have consistently demonstrated a sophisticated ability to adapt to constantly evolving market dynamics by developing specialized and tailored pricing and aggregation models while maintaining a disciplined underwriting approach. We typically seek out capacity-driven layers with attractive pricing, often focusing on dislocated markets, and look to ensure successful and sustainable growth in this segment through developing and maintaining an excellent broker network. This relationship-driven, flexible approach enables underwriters to identify additional underwriting opportunities from existing clients for providing cover on other related lines of business.

Bespoke

For the year ended December 31, 2023, the Bespoke segment accounted for 20.2% of our GPW and 20.5% of our NPE with an underwriting ratio of 61.9% and a loss ratio of 24.5%. In 2023, the Bespoke segment generated $143.2 million in underwriting income. GPW in the Bespoke segment grew from $320.5 million for the year ended December 31, 2018 to $720.4 million for the year ended December 31, 2023, a compound annual growth rate of 17.6%, despite our GPW in 2020 remaining at the same level as in 2019 due to a cautious approach to underwriting in light of political and economic uncertainties arising from the COVID-19 pandemic. During the period from 2018 to 2023, our average underwriting ratio was 59.8%. For the three months ended March 31, 2024, our Bespoke GPW was $153.5 million, compared to $150.8 million for the three months ended March 31, 2023. Credit & Political Risks accounted for 12% and Other Bespoke risk 7% of our GPW for the twelve months ended March 31, 2024.

The Bespoke segment business focuses primarily on highly tailored, innovative and specialized products, where the buying motivation is often driven by regulatory capital relief, capital efficiency or transaction facilitation versus more traditional drivers of insurance needs. The portfolio includes policies covering Credit & Political Risk and Other Bespoke risk transfer opportunities, including political violence and terrorism, limited

41

cyber reinsurance, tax liabilities, title, transactional liabilities and other bespoke solutions to fit our clients’ needs. Given the increased global conflict and national economies shifting further to intellectual property driven value, we believe that the Bespoke segment continues to see significant opportunity for beneficial pricing, terms and conditions and growth. The relationships we have formed with clients and brokers, the underwriting expertise required, and nature of the underlying risks create a higher barrier to entry and help us maintain our position as a leader in the industry. Typically, these lines do not follow the established (re)insurance cycle and are largely influenced by prevailing economic conditions at a given time. As such, these products require highly specialized pricing and other models tailored to the risk profile. For example, for certain significant risk transfer transactions, pricing is largely driven by counterparty credit quality which has low correlation with the current (re)insurance cycle and high correlation with the overall economy and macro events. As a result, Bespoke policies follow a different and diversified loss pattern relative to our Specialty and Reinsurance segments.

The Bespoke portfolio has several economic features that we believe are financially attractive. The contracts often have multi-year tenors, and the products are generally expected to have low and stable attritional loss ratios over the exposure period. The combination of longer tenor and lower expected loss experience creates the potential to capture additional embedded value as premiums are earned over the exposure period under U.S. GAAP. Additionally, the contracts are highly capital-efficient as these risks tend to have little or no correlation to peak natural catastrophe perils driving a higher return on equity than other lines. Furthermore, the contracts typically have customized provisions rather than standard market contractual provisions, creating opportunities to optimize pricing and establish proprietary, recurring relationships with clients. The custom and direct nature of the business have allowed us to lead on substantially all of our contracts creating tailored terms, conditions and pricing.

The Bespoke segment benefits from a program of reinsurance protections which are tailored across product lines. The program incorporates facultative covers as well as proportional and non-proportional treaties including aggregate, occurrence and per risk products, which reduce the impact of frequency and severity claims, and protect capital.

Reinsurance

For the year ended December 31, 2023, the Reinsurance segment accounted for 17.2% of our GPW and 13.8% of our NPE with an underwriting ratio of 36.5% and a loss ratio of 9.3%. In 2023, the Reinsurance segment generated $161.0 million in underwriting income. GPW in the Reinsurance segment grew from $328.0 million for the year ended December 31, 2018 to $617.3 million for the year ended December 31, 2023, a compound annual growth rate of 13.5%. During the period from 2018 to 2023, our average underwriting ratio was 76.9%. For the three months ended March 31, 2024 our Reinsurance GPW was $326.8 million compared to $260.4 million for the three months ended March 31, 2023. Our Reinsurance segment from 2018 to 2023 accounted for 47.3%, 45.7%, 41.7%, 38.7%, 20.1% and 17.2%, respectively, of our GPW. Property Reinsurance accounted for 17% and other reinsurance 1% of our GPW for the twelve months ended March 31, 2024.

Our Reinsurance segment consists of an actively managed, primarily residential property catastrophe reinsurance book, with closely controlled aggregates using FireAnt, TFP’s proprietary aggregation and analytics system, to monitor exposures in real time. The Reinsurance segment also includes property retrocession and a limited amount of composite and multi-class asset reinsurance. In the context of excess of loss reinsurance products, we focus on underwriting attachment points largely exposed only to true catastrophe events. The portfolio is global in nature with a strong North American concentration and smaller exposures in Japan, Europe, Australasia and elsewhere throughout the world. The Reinsurance segment benefits from a program of retrocession protections which are tailored across product lines. The program incorporates proportional and non-proportional treaties including aggregate, occurrence and parametric products such as cat bonds and industry loss warranties, which reduce the impact of frequency and severity claims, and protect capital. We believe our strategy of pursuing closely controlled aggregates and focusing on residential portfolios in the Reinsurance segment helps keep volatility lower than a portfolio with a greater focus on commercial occupancies.

42

We benefit from TFP’s sophisticated analytics capabilities and live aggregation tools, excellent relationships with a blend of regional and nationwide carriers (both in the United States and internationally), and strong retail and wholesale broker relations in the distribution of our products. Since 2021, we have developed a view of risk informed by thorough analysis and discussions with weather and forecasting experts. We have concluded that the effects of climate change on perils such as hurricanes, convective storms, floods and wildfires are not currently represented adequately in current vendor models. As such, we have superimposed our own expectations of frequency and severity on third-party vendor models, to form a base for exposure and aggregation tracking.

We have taken proactive steps to reduce volatility and reshape our Reinsurance portfolio to focus only on clients with stronger financial and loss adjustment capabilities and the resources to adjust and manage high volumes of claims in-house. As a consequence, the property reinsurance portfolio was reduced in 2022 and remained at reduced levels throughout 2023. We are increasingly deploying reinsurance capital across large-scale, well-resourced national accounts away from smaller regional underwriters, who we believe are less able to adjust and manage large catastrophe events. We have reduced our exposure to the middle layers of treaty accounts which are more exposed to increased frequency and severity of losses as a result of climate change and secondary perils associated with floods and wildfires without commensurate increases in rates. We expect the impact of these changes to improve the quality of our natural catastrophe-exposed portfolios and reduce volatility. As ever, we will continue to leverage a nimble underwriting approach to adapt to constantly evolving market dynamics to source business when favorable market conditions are present. If there is an increase in property catastrophe rates, as well as favorable terms and conditions, we would intend to capitalize on those trends and dislocations.

Underwriting and Reinsurance Purchasing

We purchase reinsurance to cover the potential accumulation or aggregation of exposures and to cover specific business written when warranted. At December 31, 2023 we had reinsurance balances recoverable on reserves for losses and loss adjustment expenses of $1,108.6 million (December 31, 2022: $976.1 million) and reinsurance balances recoverable on paid losses of $182.7 million (December 31, 2022: $159.4 million). The reinsurance we purchase takes the form of quota share, aggregate, stop loss and excess of loss programs, catastrophe bonds and industry loss warranties. We evaluate the financial condition of our reinsurers regularly and monitor concentrations of credit risk with reinsurers. All our reinsurance premiums ceded have been placed with reinsurers that are rated “A-” or higher by A.M. Best or S&P, other than four reinsurers that are rated “B++”. Where an insurer does not have a credit rating, Fidelis Insurance Group generally receives collateral, including letters of credit and trust accounts. In some cases, TFP will be afforded discretion to purchase reinsurance for us from a non-rated source, subject to full collateralization of policy limits ceded under such reinsurance (for example, through purchase of industry loss warranties) or to seek direct access to capital markets (for example, through catastrophe bonds). At December 31, 2023 the three largest balances by reinsurer accounted for 24.0%, 7.9% and 5.5%, compared to 25.3%, 6.0% and 5.0% at December 31, 2022, of the total balance recoverable from reinsurers on paid and unpaid losses. Under the Framework Agreement, we have delegated authority to design and place such outwards reinsurance to TFP in conjunction with the overall management of our book of business.

The amount of reinsurance we desire to purchase and our reasons for purchasing reinsurance will vary over time. We may purchase reinsurance to manage our capital and the volatility of our underwriting results more effectively or otherwise to facilitate the exit of certain business. This may include, inter alia, increasing our protection from underwriting risks, increasing our overall ability to deploy meaningful line sizes, reducing and spreading the risk of loss on our insurance and reinsurance business and limiting our exposure to multiple claims arising from a single occurrence.

On at least an annual basis, FIHL and TFP agree specific parameters in respect of which TFP may procure outwards reinsurance cover on behalf of FIHL (the “Outwards Reinsurance Strategy”). TFP is delegated authority to purchase and alter outwards reinsurance cover for and on behalf of the applicable operating

43

subsidiary, provided that (i) the proposed outwards reinsurance cover is consistent with the parameters set out in the Outwards Reinsurance Strategy; and (ii) the underwriting performance of the insurance business in the applicable year is within the pre-agreed parameters set out in the Outsourced TFP Subsidiary Specific Underwriting Plan. However, prior to effecting such outwards reinsurance cover, TFP must obtain the approval of the relevant operating subsidiary’s Chief Underwriting Officer, who must respond to such proposal within two business days. Placements outside of the Outwards Reinsurance Strategy will be subject to a longer turnaround time as there is more substantive review to be conducted.

When we purchase reinsurance protection, we cede to reinsurers a portion of our risks and pay premiums based upon the transferred risk or perils of the subject, right or interest protected by the reinsurance. Although the reinsurer will be liable to us in respect of the business ceded, we retain the ultimate liability in the event the reinsurer is unable to meet its obligations at some later date.

When purchasing outwards reinsurance, TFP is obliged to ensure that the placement of outwards reinsurance is within the defined terms of our counterparty risk appetite in respect of both the related credit exposure and aggregate exposure. They are also obliged to ensure that the outwards reinsurance purchased is in line with the Solvency II eligibility requirements for risk mitigation techniques, including but not limited to:

Furthermore, Fidelis Insurance Group has the right to arrange additional outwards reinsurance protections for its own behalf, separate and in addition to the outwards reinsurance purchased by TFP in respect of Fidelis Insurance Group.

Our approach is to underwrite (re)insurance business within a process-driven, disciplined innovative and analytical framework with a focus on profitability while also delivering superior solutions for clients and brokers.

Key considerations within this process include (i) adequacy of underlying rates for each class of business and territory based upon our in-house proprietary view of risk; (ii) the reputation of the proposed (re)insured; (iii) the geographic area in which the (re)insured does business, together with our catastrophe exposures and our aggregate exposures in that area; (iv) historical loss data for the (re)insured and, where available, for the industry as a whole in order to compare the historical loss experience to industry averages; (v) projections of future loss frequency and severity; (vi) if relevant, the perceived financial strength of the (re)insured; as well as (vii) certain ESG factors.

The Outsourced TFP Underwriting Plan, the Framework Agreement and the Delegated Underwriting Authority Agreements set out the parameters within which TFP ensures the overall balance of the (re)insurance portfolio is aligned with our strategic objectives. The annual business planning process is a collaborative process between us and TFP and is subject to multiple levels of review and challenge.

44

We focus on four key principles governing our underwriting and risk selection approach and strategy, which govern the risk appetite and tolerances outlined in the Outsourced TFP Underwriting Plan:

Investment Operations

Our investment strategy is focused on delivering attractive and stable investment income and an above average risk-adjusted total return through all market cycles while maintaining appropriate investment portfolio liquidity and credit quality to meet the requirements of our clients, rating agencies and regulators and support our underwriting activities.

Our investments are principally managed by two external investment managers through individual investment management agreements. Our Chief Investment Officer monitors activity and performance of the external managers on a regular basis and reports to the Board on at least a quarterly basis. At December 31, 2023, our investments consisted primarily of a diversified portfolio of fixed maturity securities (including U.S. Treasuries, non-U.S. government bonds, government agency bonds, corporate bonds, mortgage and other asset-backed securities), and a small allocation to other investments. See Item 18. Financial Statements—Note 5. Investments of the 2023 Annual Report.

The Investment Committee of our Board establishes investment policies and guidelines and supervises our investment activity. The Investment Committee regularly monitors our overall investment results and performance against our investment objectives, benchmarks, risk appetite and guidelines contained in the investment policy. Our current investment policy contains a prescriptive set of permitted investments and prohibited asset classes, guidelines specifying minimum criteria on the overall credit quality (in addition to individual issuer credit quality), ESG parameters, designed to be value accretive, and liquidity characteristics of the portfolio and includes limitations on the size of certain holdings and restrictions on purchasing certain types of securities and other investments. Any material changes to our investment objectives, risk appetite and guidelines would require Board approval, and the Board will also be required to consider the impact of any such proposed changes in light of their general compatibility with Fidelis Insurance Group’s business plan. See Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions of the 2023 Annual Report.

45

Our management team and the Investment Committee review our investment performance and assess credit and market risk concentrations and exposures to issuers. We follow an investment strategy designed to emphasize the preservation of capital and provide sufficient liquidity for the prompt payment of claims. Our investment portfolio is diversified across sectors and issuers, and we have taken a number of steps to ensure that we hold sufficient cash available to meet our obligations. At December 31, 2023, 22.4% of our total cash, cash equivalents and investments was held in cash and cash equivalents (including restricted cash and cash equivalents) and 76.5% of our total cash, cash equivalents and investments was invested in fixed maturity securities and short-term investments (with 13.3% of our total cash, cash equivalents and investments rated “BBB” and one security (0.2%) which was rated “BB”).

Claims Management

Under the terms of the Framework Agreement and the respective Delegated Underwriting Authority Agreements, claims management activities are partially delegated to TFP, with Fidelis Insurance Group retaining an oversight function and ultimate approval authority in respect of all claims relating to large losses. TFP employs a staff of experienced claims professionals who are obliged to operate within the parameters set forth in the Framework Agreement and the respective Delegated Underwriting Authority Agreements, which provide for a delegated claims authority up to a maximum monetary threshold. Claims that exceed the delegation threshold must be referred back to us for oversight and involvement in resolution within predefined timelines, and claims subject to coverage disputes and/or litigation will be handled by a separately agreed procedure.

The claims professionals employed by TFP work closely with its underwriting team to achieve consistency and efficiencies across all lines of business. We are committed to offering prompt and professional claims service to policyholders and service providers and TFP has, on our behalf, developed processes and internal business controls for identifying, tracking and settling claims.

The key responsibilities of the claims management departments include:

Reserves for Losses and Loss Adjustment Expenses

Reserve estimates are derived by us after extensive consultation with the underwriters and actuaries employed by TFP, actuarial analysis of the loss reserve development, comparison with industry benchmarks and preliminary contract level loss reserve estimates prepared by TFP. The reserves for losses and loss adjustment expenses include an amount determined from reported claims and estimates based on historical loss experience and industry statistics for IBNR losses using a variety of actuarial methods. For additional discussion of our reserves, refer to Item 18. Financial Statements—Note 12. Reserves for Losses and Loss Adjustment Expenses of the 2023 Annual Report.

46

Loss reserves represent estimates, at any given time, of what we ultimately expect to pay on claims, are based on facts and circumstances then known, and it is probable that the ultimate liability may exceed or be less than such estimates. Even actuarially sound methods can lead to subsequent adjustments to reserves that are both significant and irregular due to the nature of the risks written. Loss reserves are inherently subject to uncertainty. In establishing the reserves for losses and loss adjustment expenses, we make various assumptions relating to the pricing of reinsurance contracts and insurance policies and also considering available historical industry experience and current industry conditions. The timing and amounts of actual claim payments related to recorded reserves vary based on many factors, including large individual losses and changes in the legal environment, as well as general market conditions. The ultimate amount of the actual claim payments could differ materially from our estimated amounts. Certain lines of business have loss experience characterized as low frequency and high severity. This may result in significant variability in loss payment patterns and, therefore, may impact the related investment management process in order to be in a position, if necessary, to make these payments. The unpaid reported reserves for losses and loss adjustment expenses are established by management based on reports from brokers, ceding insurers and insureds and represent the estimated ultimate cost of events or conditions that have been reported to, or specifically identified by us. Generally, it is anticipated that reserves will be established without regard to whether we may subsequently contest the claim. Fidelis Insurance Group carries out its reserving process with input provided by TFP’s claims and actuarial teams. Ultimate ownership and sign-off responsibility over our reserving remains with us. The reserves for IBNR losses and loss adjustment expenses are established by our management based on actuarially determined estimates of ultimate losses and loss adjustment expenses, and other related data and analysis to be provided to us by TFP. Inherent in the estimate of ultimate losses and loss adjustment expenses are expected trends in claim severity and frequency and other factors which may vary significantly as claims are settled, and accordingly, ultimate losses and loss adjustment expenses may differ.

These estimates are reviewed regularly and, as experience develops and new information becomes known, the reserves are adjusted as necessary. Such adjustments, if any, will be recorded in losses and loss adjustment expenses in the period in which they become known. IBNR reserves are calculated on a best estimate basis and are established by our management based on a combination of management’s professional judgment and various actuarial methods, growing loss experience, historical (re)insurance industry loss experience, estimates of pricing adequacy trends and other related data and analysis to be provided by TFP. Due to the limited historical data available, and limited loss experience available to us due to our relatively short period of operations, reliance is placed upon industry data and a review of individual policies. Estimates are calculated at the lowest level line of business, separately for gross and ceded, and for attritional, large and catastrophic claims.

The reserve estimates contain an inherent level of uncertainty, and actual results may vary, potentially significantly, from the estimates we have made. Reserves are reviewed on a quarterly basis and estimates are adjusted to reflect emerging claims experience. We are supported by an external loss reserve specialist, which reviews our reserves annually.

Other principal actuarial methods, and associated key assumptions, used to perform our loss reserve analysis include paid and incurred chain ladder, paid and incurred Bornhuetter-Ferguson method and credible claims reserves. We may however employ a number of different reserving methods depending on the segment, the line of business, the availability of historical loss experience and the stability of that loss experience. Over time we may determine to give additional weight to our historical loss experience in our reserving process due to the then-applicable maturation of our reserves, and the increased availability and credibility of the historical experience.

Insurance Regulations

Our insurance operating subsidiaries are subject to insurance and reinsurance laws and regulations in the jurisdictions in which they operate, the most significant of which are Bermuda, Ireland and the United Kingdom. We hold capital in excess of the minimum statutory capital and surplus requirements in each of those locations. Please refer to Item 18. Financial Statements—Note 16. Statutory Requirements and Dividend Restrictions of the 2023 Annual Report for further details of the requirements in each jurisdiction.

47

Insurance Market Conditions

We believe we have significant market opportunities given our ability to innovate and adapt to evolving market conditions. Global economic and industrial development, population increases, greater product awareness and distribution, as well as inflation continue to drive increased need for insurance and reinsurance. The current insurance and reinsurance market environment has experienced a prolonged period of rate increases, structural enhancements and continued improvement of terms and conditions. In 2022, following a period of higher loss ratios due to the frequency and severity of catastrophes, many of our competitors reevaluated and reduced their catastrophe reinsurance business, leading to a decrease in available capacity and a hardening of rates, which persisted into 2023 across both property reinsurance and D&F lines. Specialty markets such as aviation, marine and cyber have seen significant rate hardening in recent years driven by underperformance and market and geopolitical uncertainty. We believe that this combination of factors is driving a sustainable and favorable market environment, with a focus on risk management, disciplined risk selection, improved terms and profitable business, which presents significant market opportunities for us. Property D&F pricing is at the mature phase of the cycle, with rating at the highest levels in the past two decades. Marine cargo prices are elevated and pricing in aviation lines remain hard. We believe the favorable rate environment should persist for the near future across the lines of business on which FIHL focuses.

We believe that the following prevailing factors will contribute to sustained pricing levels across multiple lines:

48

We believe that these market conditions have led to compelling dislocated underwriting opportunities.

Strengths

We believe that our competitive advantages are based on the following key strengths:

We focus on building first mover advantages across our markets. Our product portfolio evolves in response to client demand for tailored products and our market-driven, real-time assessment of risk.

Our strategy is to increase line sizes where appropriate, take the lead in requiring rate changes and establish ourselves as the “go to” market for solutions through our in-force portfolio and new classes of specialty and bespoke products. Depending on market conditions, we exercise discretion in coordination with TFP, where applicable, to increase retention by reducing outwards quota shares to take further advantage of the

49

continued hardening of rates. Similarly, we may also coordinate with TFP to increase line sizes as conditions warrant. We intend to grow specialty classes by writing meaningful line sizes to further push rate increases, achieve differential pricing through leadership and access new classes where there is significant market dislocation. We expect to grow our specialty and bespoke products through a combination of organic growth of our already well-established footprint, systematic cross-selling to clients and innovative new products while maintaining quality underwriting information, high-quality risk selection and multi-line aggregation tools and technology.

The performance of our business portfolio written by TFP is primarily driven by the capabilities of the TFP management team, led by Richard Brindle, who is the Chairman and CEO of TFP. Mr. Brindle brings 40 years of experience in the insurance industry and is known for his track record of outperformance across Lloyd’s syndicates and Lancashire under his leadership. We secured a long term agency relationship with TFP under the Framework Agreement, with right of first access to its underwriting business, and strong economic and strategic alignment between the two businesses.

Fidelis Insurance Group and TFP are both members of ClimateWise. The ClimateWise Principles require members to disclose their assessment of the risks and opportunities of climate change and are aligned with the Task Force on Climate-related Financial Disclosure framework. Further, TFP was a founding member of The Poseidon Principles on Marine Insurance, which pledges a net zero marine hull insurance portfolio by 2050. We actively support the transition to a net zero global economy by making renewable energy one of our classes of underwriting through TFP, including the construction of offshore wind turbine farms.

We maintain underwriting and investment restrictions that align with our ESG principles as well as those principles that are consistent with leading to long-term value, such as excluding a number of sectors that we believe pose risks of harm to people, animals and the environment. Furthermore, FIHL’s investment

50

portfolio is managed in a manner that is consistent with Fidelis Insurance Group’s sustainability principles and its ESG objectives. The fixed maturity portfolio has a minimum requirement for investments that meet ESG thresholds, prohibits investing in issuers with poor ESG ratings, and restricts exposure to certain industries and behaviors.

Further, the ERG works to enhance employee engagement by providing opportunities that match their workplace values. We believe that this voluntary, employee-driven initiative encourages community, support, and advocacy, involving diversity, equity, inclusion, employee engagement, environmental concerns, and philanthropy. In 2024, the ERG is prioritizing charitable causes aligned with our company values and community impact, which we hope to result in impactful grants, more cultural exchanges, and enhanced educational resources on diversity.

Our Strategy

We are set up to be nimble, thoughtful, and efficient decision-makers and we believe that we are able to respond quickly to an ever-changing world and a constantly evolving marketplace. We believe these attributes allow us to target opportunities that we expect to offer a compelling balance of risk and reward that creates long-term value through the cycle by delivering consistent returns to shareholders. We intend to scale our business to reflect market conditions and pursue prudent capital management and profitable underwriting on a loss ratio and combined ratio basis in pursuance of our financial targets.

Our strategy involves the following:

We seek to manage volatility over the cycle in our underwriting result by writing a balanced and diversified portfolio of predominantly specialty business, maintaining strict underwriting and pricing discipline and strategic reinsurance protection. Our strategy has frequently generated better risk-adjusted returns than many of our competitors who focus on specific niches exclusively or have large exposure to natural catastrophe reinsurance. We have taken measures to actively manage and in many cases reshape our natural catastrophe exposure in light of greater severity and frequency of catastrophe events and concerns around global climate change.

We leverage our relationship with TFP to continue disciplined underwriting with the use of TFP’s integrated technology solutions, including monitoring real-time market conditions to best capture unique opportunities. TFP’s daily processes, which we actively participate in, will enable it, on our behalf, to maintain a live, dynamic picture of the current underwriting environment that drives daily underwriting decisions, including the daily UMCCs. We believe that our risk selection as a result of these processes should allow us to deploy significant line sizes that in turn allow us to be a “rate maker” rather than a “rate taker.”

51

A recent example of such innovation is the cooperation between Fidelis Insurance Group and TFP to launch Itasca MGA, an aviation-focused managing general agent (“MGA”) of Pine Walk, a wholly owned subsidiary of TFP. Itasca MGA specializes in underwriting, structuring and managing risks associated with secured commercial aviation financing. We believe with the experience and expertise of the Itasca MGA team and their partnerships with established market participants that they are positioned to become one of the key solution providers for global airlines and the broader aviation market.

Furthermore, in March 2024, Fidelis Insurance Group jointly announced with TFP the launch of Syndicate 3123. Fidelis Insurance Group’s participation in Syndicate 3123 includes a 9.9% contribution of Syndicate 3123’s total capital requirement for the second half of 2024, and a variable quota share of the book of business underwritten by Syndicate 3123. TFP is also contributing 9.9% of Syndicate 3123’s capacity, further demonstrating alignment of interest between the parties, with individual members at Lloyd’s and other investors providing the remainder of the capital requirements.

We have an exclusive right of first access to TFP’s underwriting business during the term of the Framework Agreement. Based on Fidelis’ historical experience, we expect this long-term partnership to deliver strong returns to our shareholders, primarily driven by our underwriting results. We aim to be good stewards of capital by effectively balancing capital deployment across market opportunities with capital distributions to our shareholders.

Subject to the exclusivity obligations set out in the Framework Agreement (see Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Framework Agreement—Exclusivity, Rights of First Offer and Rights of First Refusal of the 2023 Annual Report), we continue to explore additional avenues for the deployment of capital into new underwriting opportunities by targeting strategic partners across lines of business which support our growth strategy, in order to achieve diversification and meet return criteria.

We maintain a strong, highly rated balance sheet with total capital of $3.0 billion as of December 31, 2023. We have had net favorable prior year reserve development every year since inception, demonstrating our consistent and prudent approach to reserving. In addition, our focus is on short-tail lines with carefully managed catastrophe exposure and no longer tail casualty business. This approach, and our minimal exposure to social inflation risk, reinforces our confidence that we can avoid meaningful reserve volatility moving forward. Further, we continue to strategically use reinsurance, including our 20% whole account quota share with Travelers that recently renewed for a second year, as a flexible and aligned source of capital.

52

Looking ahead, our primary focus remains capitalizing on the attractive growth opportunities to deliver profitable returns while also continuing to explore ways to optimize our capital structure and create value for shareholders. Our strategic capital management priorities include: allocating capital back into the business and deploying capital into attractive underwriting opportunities; reassessing our outwards reinsurance purchasing program; and returning capital to shareholders through a combination of the Share Repurchase Program and our dividend policy (see “Dividend Policy”).

In relation to the Share Repurchase Program, we reported in Exhibit 99.2 of the Q1 2024 Quarterly Report that during the three months ended March 31, 2024, we repurchased 357,602 Common Shares for $5.0 million. Subsequently, from April 1, 2024, to May 17, 2024, we repurchased an additional 1,026,968 Common Shares for $18.9 million.

Competition

The (re)insurance industry is highly competitive and we compete with major insurers, reinsurers and alternative capital managers. While there is no one direct competitor for us given our business strategy, and we may have other categories of peer groups or competitors, our competitors may include multi-line property and specialty (re)insurers such as AXIS Capital Holdings Limited, Beazley plc, Conduit Holdings Limited, Everest Group Ltd, Hamilton Insurance Group Ltd, Hiscox Ltd, Lancashire Holdings Limited, Markel Group Inc, and W.R. Berkley Corporation. The industry has seen and continues to see a trend of consolidation, and we believe that our unique business model and focus on quality, service and experience over scale differentiates us from our competitors seeking growth from mergers or acquisitions. See “Risk Factors” and Item 3. Key Information—D. Risk Factors of the 2023 Annual Report.

Employees

At March 31, 2024, we employed 79 persons on a full time basis, of which 21 were in Bermuda, 46 were in the United Kingdom, and 12 were in Ireland. Of these, 16 worked primarily in (re)insurance business related functions, such as actuarial, claims, risk and underwriting; 20 worked primarily in operational functions, such as business operations, facilities, office management and IT; 23 worked primarily in finance functions, such as finance and investments; and 20 worked primarily in support and other functions, such as chief executive office, audit, compliance, HR, and legal.

Facilities

We lease office space in Bermuda, Ireland and the United Kingdom. We renew and enter into new leases in the ordinary course of business.

53

Information Technology

We require complex and extensive IT systems to run our business and are reliant on third parties, including TFP, for the provision of important services, including finance systems and processes and IT infrastructure including software, claims management and investment management services. We have autonomy over our financial and regulatory reporting, with use of dedicated Oracle Fusion general ledger and Solvency II reporting tools.

The technology platforms were transferred to TFP as part of the Separation Transactions. Although the proprietary tools and systems including the Prequel Policy Administration system, the Jarvis Data Warehouse, and the FireAnt analytics system are owned by TFP, they are licensed for use by us as appropriate pursuant to the outsourcing arrangements. See Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Other—Licensing Arrangements of the 2023 Annual Report.

Legal Proceedings

Similar to the rest of the insurance and reinsurance industry, we are from time to time subject to litigation and arbitration in the ordinary course of business. We may also be subject to other potential litigation, disputes and regulatory or governmental inquiry from time to time in the ordinary course of business. While it is not feasible to predict or determine the ultimate outcome of the pending or threatened proceedings, management does not believe that the outcome of these proceedings, including those discussed below, will have a material adverse effect on the financial condition of Fidelis Insurance Group, after consideration of any applicable reserves.

Following Russia’s invasion of Ukraine on February 24, 2022, government sanctions were introduced prohibiting various commercial and finance activities in Russia, including leasing of aircraft in the aviation industry to any person in Russia, or for use in Russia. Aircraft lessors issued notices to airlines and lessees in Russia purporting to terminate the leasing of aircraft (and other parts such as spare engines) and requiring that the airlines return the assets. Many of the relevant aviation authorities where the aircraft are registered have also since suspended the certificates of airworthiness of such aircraft. Some aircraft are yet to be returned and aircraft lessors filed various insurance claims under their insurance policies for loss of the unreturned aircraft. The insurers have denied the claims and the lessors have instituted proceedings in the U.K., the U.S. and Ireland against upwards of 60 (re)insurers, including certain Group entities. Provision has been made in Fidelis Insurance Group’s reserves for losses and loss adjustment expenses for potential exposures relating to the Ukraine Conflict, a considerable majority of which are reserves reflecting our estimate for potential loss claims relating to leased aircraft within Russia, including the related litigation proceedings. See Item 5. Operating and Financial Review and Prospects—Operating Results—Recent Developments—Russia-Ukraine Conflict.

This is an unprecedented event, which, as of the date of this prospectus, is anticipated to continue for a protracted period of time and presents unique circumstances and coverage issues in respect of both the gross loss and consequent extent of the reinsurance recoveries, which will continue to be unresolved until the multiple courts rule on the merits of the lawsuits. The situation is continuously evolving, including with respect to explorative discussions ongoing between Western leasing firms and Russian airline operators for the sale of some of the unreturned aircraft to the Russian operators. Such discussions, if successful, may lead to a reduction in any potential exposures under the relevant insurance policies. See Item 5. Operating and Financial Review and Prospects—Operating Results—Recent Developments—Russia-Ukraine Conflict, Item 3. Key Information—D. Risk Factors—Risks Relating to Recent Events—The full extent of the impacts of the ongoing Ukraine Conflict on the (re)insurance industry and on the Group’s business, financial condition and results of operations, including in relation to claims under the Group’s (re)insurance policies, are uncertain and remain unknown and Item 3. Key Information—D. Risk Factors—We are subject to litigation which could adversely affect our business and results of operations, of the 2023 Annual Report.

Director Independence

As foreign private issuer, under the listing requirements and rules of the 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

59

consist fully of independent directors, subject to certain phase-in schedules. The listing standards of the NYSE require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent, following a phase-in period. In addition, the listing standards of the NYSE require that audit committee members satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and that compensation committee members satisfy independence criteria set forth in the NYSE Listed Company Manual. Nevertheless, the listing standards further provide that a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The Board has affirmatively determined that each of Matthew Adams, Christine Dandridge, Charles Collis, Cathy Iberg, Daniel Brand, 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. As a result, in accordance with listing standards of the NYSE, a majority of our directors are independent.

Family Relationships

There is no family relationship between any director or senior manager of Fidelis Insurance Group and any other director or senior manager or any person nominated to become a director or senior manager. As explained in Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management—Family Relationships of the 2023 Annual Report, each of the Founders and TFP HoldCo has the right to nominate one individual to serve as a director on the Board. Other than these arrangements, there are no arrangements or understandings with major stockholders, customers, suppliers or others pursuant to which any director or senior manager of Fidelis Insurance Group was selected for such position.

Board Composition

FIHL’s business and affairs are managed under the direction of the Board.

The Amended and Restated Bye-Laws provide that the Board will be divided into three classes, designated Class I, Class II and Class III, as nearly equal in number as possible, with the directors in each class serving staggered three-year terms, and one class being elected each year. Our current directors are divided among the three classes as follows:

The classified board will remain in place until the annual general meeting occurring in 2030, following which, all of the directors shall be of one class and shall serve for a term ending at the next following annual general meeting.

60

See Item 19. Exhibits—Exhibit 2.1 Description of Securities of the 2023 Annual Report.

When considering whether directors and nominees have the experience, qualifications, attributes or skills, taken as a whole, to enable the Board to satisfy its oversight responsibilities effectively in light of our business and structure, the Board focused primarily on each person’s background and experience as reflected in the information discussed in each of the directors’ individual biographies set forth in “—Biographical Information” above. The effectiveness of the Board is reviewed annually. We continue to believe that our directors provide an appropriate mix of experience and skills relevant to the size and nature of our business.

Role of the Board in 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 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.

Foreign Private Issuer Exemption

As a “foreign private issuer,” as defined by the SEC, FIHL is permitted to follow, and does follow, home country corporate governance practices instead of certain corporate governance practices required for U.S. domestic issuers, provided that FIHL discloses which requirements it is not following and the equivalent requirement in Bermuda (i.e., its home country). FIHL intends to maintain compliance as a foreign private issuer under the applicable corporate governance requirements of the Sarbanes-Oxley Act, the rules adopted by the SEC, and the NYSE corporate governance rules and listing standards.

FIHL relies on the foreign private issuer exemption to certain of the NYSE’s corporate governance standards with respect to matters related to its independent director oversight of executive compensation, proxy solicitation, quorum and shareholder approval. FIHL may decide to rely upon the foreign private issuer exemption for purposes of opting out of some or all of the corporate governance rules applicable from time to time to U.S. domestic companies.

Because FIHL is a foreign private issuer, its directors and senior management will not be subject to short-swing profit and insider trading reporting obligations under Section 16 of the Exchange Act. All shareholders, however, will be subject to the obligations to report changes in share ownership under Section 13 of the Exchange Act and related SEC rules.

Committees of the Board

The Board has an audit committee, compensation committee, investment committee, risk committee, and nominating and corporate governance committee. The Board may have such other committees as it shall determine from time to time. Each of the standing committees of the Board has the composition and responsibilities described below. Copies of each committee’s charter are posted on our website, www.fidelisinsurance.com/investors. The reference to our website address does not constitute incorporation by reference of the information contained at or available through our website, and you should not consider it to be a part of this prospectus.

Audit Committee

The Audit Committee is formed of the following directors: Matthew Adams (Committee Chair), Cathy Iberg, Dana LaForge, and Helena Morrissey, each of whom is independent for purposes of the NYSE rules and Rule 10A-3 under the Exchange Act.

61

Pursuant to its terms of reference, the Audit Committee’s role is one of oversight. Its responsibilities include appointing and evaluating the performance and independence of the Company’s independent auditor. Additionally, the Audit Committee also reviews the financial statements and annual audits of the Company, oversees the internal audit function, reviews and discusses with the Board earnings press releases, reviews procedures for handling complaints in relation to accounting, internal accounting controls or auditing matters and assists the Board in assessing and providing oversight regarding the Company’s internal controls and risk management systems. The Audit Committee is responsible for reviewing its terms of reference on an annual basis and shall review its own performance at least once per year.

The Board determined that each of the members of the Audit Committee is financially literate as such term is defined by applicable NYSE and SEC requirements. In addition, the Board has determined that Mr. Matthew Adams qualifies as having accounting or related financial management expertise pursuant to the NYSE requirements and is an “audit committee financial expert” pursuant to the rules and regulations of the SEC.

Compensation Committee

As a foreign private issuer, we are not required to have a compensation committee or a compensation committee consisting only of independent directors. However, our Board has established the compensation committee (the “Compensation Committee”), which consists entirely of independent directors for the purposes of the NYSE rules. The Compensation Committee is formed of the following directors: Helena Morrissey (Committee Chair), Daniel Brand, Charles Collis, Christine Dandridge, Daniel Kilpatrick and Dana La Forge.

Pursuant to its terms of reference, the Compensation Committee is responsible for reviewing, assessing and making recommendations to the Board regarding the Company’s incentive-based and equity-based compensation plans (including long-term incentive plans) and the Company’s processes and procedures for considering and determining the compensation of its directors and senior executives. The Compensation Committee is also responsible for developing and recommending to the Board one or more policies for the recovery or clawback of erroneously paid compensation, monitoring compliance with such policies and making any necessary revisions to such policies as may be required from time to time. The Compensation Committee is responsible for reviewing its terms of reference on an annual basis and shall review its own performance at least once per year.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee is formed of the following directors: Helena Morrissey (Committee Chair), Matthew Adams, Daniel Brand, Charles Collis, Christine Dandridge, Cathy Iberg and Daniel Kilpatrick, each of whom is independent for purposes of the NYSE rules.

Pursuant to its terms of reference, the Nominating and Corporate Governance Committee is responsible for overseeing FIHL’s corporate governance and procedures by developing a set of guidelines and making recommendations to the Board to ensure compliance with laws and regulations. The Nominating and Corporate Governance Committee also reviews Fidelis Insurance Group’s leadership needs by preparing and recommending nominees it thinks necessary based on vacancies and plans for succession in respect of directorship and management, using recommended selection criteria. Additionally, the Nominating and Corporate Governance Committee develops, recommends and oversees the process of annual self-evaluation for the Board as well as its own performance on an annual basis, subject to approval by the Board.

Investment Committee

The Board has established an investment committee, which consists of Cathy Iberg (Committee Chair), Daniel Brand, Dana LaForge, Hinal Patel, Daniel Burrows and Allan Decleir. Pursuant to its written charter, the investment committee is responsible for, among other things: (i) recommending investment strategy, investment risk appetite and investment risk limits to the FIHL Board; (ii) reviewing and approving new material changes to

62

the investment policy or investment managers; (iii) overseeing investment policies, guidelines and benchmarks; (iv) delegation of investment related authorities and responsibilities to sub-committees and management; and (v) monitoring investment risk, compliance, portfolio composition, investment performance and activity.

Risk Committee

The Board has established a risk committee, which consists of Daniel Kilpatrick (Committee Chair), Hinal Patel, Christine Dandridge, Matthew Adams, Daniel Burrows and Allan Decleir. Pursuant to its written charter, the risk committee is responsible for, among other things: (i) evaluating FIHL’s risk appetite and tolerances; (ii) overseeing risk management and related policies and guidelines; (iii) establishing risk policies and guidelines; and (iv) overseeing the Board’s responsibilities related to risk management exposure.

Compensation Committee Interlocks and Insider Participation

None of our executive officers currently serves, or in the past fiscal year has served, as a member of the board or compensation committee of another entity that has one or more executive officers serving on the Board or our compensation committee.

Code of Business Conduct and Ethics

The Board has adopted a code of business conduct and ethics applicable to our employees, directors and officers, including our Chief Executive Officer, Chief Financial Officer and other executive and senior officers, in accordance with applicable U.S. federal securities laws and the corporate governance rules of the NYSE. This code is a “code of ethics,” as defined in Item 406(b) of Regulation S-K under the Securities Act. Our code of ethics is available on our website, www.fidelisinsurance.com/investors/. We make any legally required disclosures regarding amendments to, or waivers of, provisions of our code of ethics on our website.

PRINCIPAL AND SELLING SHAREHOLDERS

The following table sets forth certain information regarding the beneficial ownership of Common Shares at May 17, 2024 by (i) each person who is known by us to beneficially own more than 5.0% of the Common Shares; (ii) all of our directors and senior managers as a group; and (iii) the Selling Shareholders (as defined below).

Beneficial ownership for the purposes of the following table is determined in accordance with the rules and regulations of the SEC. These rules generally provide that a person is the beneficial owner of securities if such person has or shares the power to vote or direct the voting of such securities, or to dispose or direct the disposition of such securities, or has the right to acquire such securities or such powers within 60 days.

To our knowledge, except as disclosed in the footnotes to the following table and subject to applicable community property laws, we believe that each beneficial owner identified in the table possesses sole voting and investment power over all Common Shares shown as beneficially owned by such beneficial owner.

For purposes of the table below, the percentage ownership calculations for beneficial ownership are based on 116,898,062 Common Shares outstanding at May 17, 2024. Such beneficial ownership information is presented on the following basis:

The information in the table and the footnotes below with respect to each Selling Shareholder has been obtained from that Selling Shareholder.

MATERIAL CONTRACTS AND RELATED PARTY TRANSACTIONS

Repurchase Agreement with TFP HoldCo

In connection with the adoption by our Board of a Common Share repurchase program of up to $50.0 million of Common Shares, on March 19, 2024 we entered into a repurchase agreement with one of our shareholders, TFP HoldCo (the “Repurchase Agreement”), following approval by our Audit Committee. Under the terms of the Amended and Restated Common Shareholders Agreement, upon any proposed repurchase of Common Shares by FIHL, if TFP HoldCo, acting reasonably and in good faith, determines that, as a result of such proposed repurchase it (i) would become consolidated with FIHL for accounting purposes, (ii) would hold more than 9.9% of the Common Shares and/or (iii) would become a controller of any of FIHL’s subsidiaries which are regulated pursuant to applicable regulatory law, in each case, as a result of such proposed repurchase, then it shall have the right, at its election, to (x) have a sufficient portion of its Common Shares repurchased by the Company, on the same terms as the proposed repurchase (each such election, a “Repurchase Election”) or (y) undertake a permitted transfer in respect of a sufficient portion of its Common Shares. Following written notice from FIHL that the adoption of the brokered repurchase plan under the repurchase (the “Brokered Repurchase Plan”) program might result in TFP HoldCo holding more than 9.9% of Common Shares, TFP HoldCo has elected to exercise one or more Repurchase Elections in order to avoid circumstances where TFP HoldCo would hold more than 9.9% of Common Shares. Under the Repurchase Agreement, on each day that FIHL repurchases Common Shares under the Brokered Repurchase Plan, it shall repurchase a certain number of Common Shares from TFP HoldCo at a price equal to the average price per Common Share paid by FIHL on such day under the Brokered Repurchase Plan. The repurchase mechanic follows a prescribed format designed to keep TFP HoldCo’s ownership of FIHL to below 9.8752%. As of May 17, 2024, FIHL has repurchased 101,701 Common Shares from TFP HoldCo.

We have agreed for a period of 90 days not to consent to any request by TFP HoldCo to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise dispose of, directly or indirectly, any of our common shares for a period of 90 days after the date of this prospectus, subject to the Repurchase Election under the Amended and Restated Common Shareholders Agreement.

Launch of Lloyd’s Syndicate 3123

On March 28, 2024, FIHL announced its participation in the launch of a new Lloyd’s Syndicate 3123 which is being sponsored by TFP HoldCo. It is expected that TFP Holdco’s managing agent will underwrite a diverse book of risks within Syndicate 3123 across multiple insurance and reinsurance classes, including property catastrophe, credit, political, violence, marine and aviation. Syndicate 3123 has received in principle approval from Lloyd’s, with underwriting expected to begin on July 1, 2024, subject to final approval from Lloyd’s.

FIHL intends to participate in Syndicate 3123 as a co-investor, alongside TFP HoldCo and third party private capital sourced by Hampden Agencies Limited, pursuant to which it would contribute approximately 9.9% of Syndicate 3123’s initial total capital requirement in respect of the 2024 underwriting year of account. Consistent with the Framework Agreement, the Group also intends to reinsure a variable quota share of specified lines of business underwritten by Syndicate 3123.

COMPARISON OF SHAREHOLDER RIGHTS

Prospective investors should be aware that the Bermuda Companies Act 1981 (the “Companies Act”), which applies to us, differs in certain material respects from laws generally applicable to U.S. companies incorporated in the State of Delaware and their shareholders. The following is a summary of certain significant differences between the Companies Act (including modifications adopted pursuant to our Amended and Restated Bye-Laws) and Bermuda common law applicable to us and our shareholders, on the one hand, and the provisions of the Delaware General Corporation Law applicable to U.S. companies organized under the laws of Delaware and their shareholders, on the other hand.

Duties of Directors

The Companies Act authorizes the directors of a company, subject to its bye-laws, to exercise all powers of the company except those that are required by the Companies Act or the company’s bye-laws to be exercised by the shareholders of the company. Our Amended and Restated Bye-Laws provide that our business is to be managed and conducted by the Board. In accordance with Bermuda common law, members of a board of directors owe a fiduciary duty to the company to act in good faith in their dealings with or on behalf of the company and exercise their powers and fulfill the duties of their office honestly. This duty includes the following essential elements:

The Companies Act imposes a duty on directors and officers of a Bermuda company:

The Companies Act also imposes various duties on directors and officers of a company with respect to certain matters of management and administration of such company.

Under Bermuda law, directors and officers generally owe fiduciary duties to the company itself, not to the company’s individual shareholders or members, creditors, or any class of shareholders, members or creditors. Our shareholders may not have a direct cause of action against our directors.

Under Delaware law, the business and affairs of a company are managed by or under the direction of its board of directors. In exercising their powers, directors are charged with a fiduciary duty of care to protect the interests of the company and a fiduciary duty of loyalty to act in the best interests of its shareholders. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the company. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interests of the company and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the company. However, this presumption may be

67

rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the company.

Interested Directors

Bermuda law provides that a transaction entered into by us in which a director has an interest will not be voidable by us and such director will not be liable to us for any profit realized pursuant to such transaction as a result of such interest, provided that the nature of the interest is disclosed at the first opportunity, either at a meeting of directors or in writing to the directors. While we are not aware of any Bermuda case law on the meaning of “first opportunity,” a Bermuda court will likely employ a practical interpretation of those words.

Subject to the NYSE rules and applicable U.S. securities laws, our Amended and Restated Bye-Laws do not require directors to recuse themselves from any discussion or decision involving any contract or proposed contract or arrangement in which the director is directly or indirectly interested so long as the nature of the interest is disclosed, and such director may be counted in the quorum for such meeting, unless the Board by resolution of a simple majority of the Board (which vote shall exclude the interested director) requires the director to abstain from any vote on the conflicted matter.

Under Delaware law, such transaction would not be voidable if: (i) the material facts as to such interested director’s relationship or interests are disclosed or are known to the board of directors and the board in good faith authorizes the transaction by the affirmative vote of a majority of the disinterested directors; (ii) such material facts are disclosed or are known to the shareholders entitled to vote on such transaction and the transaction is specifically approved in good faith by vote of the majority of shares entitled to vote on the matter; or (iii) the transaction is fair as to the company as of the time it is authorized, approved or ratified. Under Delaware law, such interested director could be held liable for a transaction in which such director derived an improper personal benefit.

Voting Rights and Quorum Requirements

Under Bermuda law, the voting rights of our shareholders are regulated by our Amended and Restated Bye-Laws and, in certain circumstances, the Companies Act. Generally, except as otherwise provided in the Amended and Restated Bye-Laws or the Companies Act, any action or resolution requiring approval of the shareholders may be passed by a simple majority of the shareholders. Any individual who is our shareholder and who is present at a meeting may vote in person, as may any corporate shareholder that is represented by a duly authorized representative at a meeting of shareholders. Our Amended and Restated Bye-Laws also permit attendance at general meetings by proxy, provided that the instrument appointing the proxy is in the form specified in the Amended and Restated Bye-Laws or such other form as the Board may determine.

Holders of the Common Shares have one vote for each Common Share held by them and are entitled to vote at all meetings of the shareholders.

In the event of the liquidation, dissolution or winding up of FIHL, the holders of the Common Shares will be entitled to share equally and ratably in our assets, if any, remaining after the payment of all our debts and liabilities, subject to the liquidation preference on any issued and outstanding preference securities, including our Series A Preference Securities.

If at any time, FIHL has more than one class of shares, the rights attaching to any class, unless otherwise provided for by the terms of issue of the relevant class, may be varied with the approval of the Board and with the consent in writing of the holders of a Simple Majority (as defined in the Amended and Restated Bye-Laws) of that class or with the sanction of a resolution passed by a Simple Majority at a separate general meeting of the holders of the shares of the class at which meeting the necessary quorum will be two persons at least holding or

68

representing by proxy a Simple Majority. The Amended and Restated Bye-Laws specify that the creation or issuance of shares ranking pari passu or senior with existing shares will not, unless expressly provided by the terms of issue of existing shares, vary the rights attached to existing shares.

Under Delaware law, unless otherwise provided in a company’s certificate of incorporation, each shareholder is entitled to one vote for each share of stock held by the shareholder. Delaware law provides that unless otherwise provided in a company’s certificate of incorporation or bylaws, a majority of the shares entitled to vote, present in person or represented by proxy, constitutes a quorum at a meeting of shareholders. In matters other than the election of directors, with the exception of special voting requirements related to extraordinary transactions, and unless otherwise provided in a company’s certificate of incorporation or bylaws, the affirmative vote of a majority of shares present in person or represented by proxy and entitled to vote at a meeting in which a quorum is present is required for shareholder action, and the affirmative vote of a plurality of shares present in person or represented by proxy and entitled to vote at the meeting is required for the election of directors.

Amalgamations, Mergers and Similar Arrangements

The amalgamation or merger of a Bermuda company with another company or corporation (other than certain affiliated companies) requires the amalgamation or merger agreement to be approved by the company’s board of directors and by its shareholders. Unless the company’s bye-laws provide otherwise, the approval of 75% of the shareholders voting at such meeting is required to approve the amalgamation or merger agreement, and the quorum for such meeting must be two persons holding or representing more than one-third of the issued shares of the company.

Under Bermuda law, in the event of an amalgamation or merger of a Bermuda company with another company or corporation, a shareholder of the Bermuda company who did not vote in favor of the amalgamation or merger and is not satisfied that fair value has been offered for such shareholder’s shares may, within one month of notice of the shareholders meeting, apply to the Supreme Court of Bermuda to appraise the fair value of those shares.

Under Delaware law, with certain exceptions, a merger, consolidation or sale of all or substantially all the assets of a corporation must be approved by the board of directors and a majority of the issued and outstanding shares entitled to vote on such transaction. A shareholder of a company participating in certain merger and consolidation transactions may, under certain circumstances, be entitled to appraisal rights, such as having a court determine the fair value of the stock or requiring the company to pay such value in cash. However, such appraisal right is not available to shareholders if the stock received in such transaction is listed on a national securities exchange, including the NYSE.

Acquisitions

Under Bermuda law, an acquiring party is generally able to acquire compulsorily the common shares of minority holders of a company in the following ways:

69

Delaware law provides that a parent corporation, by resolution of its board of directors and without any shareholder vote, may merge with any subsidiary of which it owns at least 90% of each class of its capital stock. Upon any such merger, and in the event the parent corporation does not own all of the stock of the subsidiary, dissenting shareholders of the subsidiary are entitled to certain appraisal rights. Delaware law also provides, subject to certain exceptions, that if a person acquires 15% of voting stock of a company, the person is an “interested shareholder” and may not engage in “business combinations” with the company for a period of three years from the time the person acquired 15% or more of voting stock.

Dissenters’ Rights of Appraisal

Under Bermuda law, in the event of an amalgamation or merger of a Bermuda company with another company or corporation, a shareholder of the Bermuda company who did not vote in favor of the amalgamation or merger and who is not satisfied that fair value has been offered for such shareholder’s shares may, within one month of notice of the shareholders’ meeting, apply to the Supreme Court of Bermuda to appraise the fair value of those shares. Under Bermuda law, each share of an amalgamating or merging company carries the right to vote in respect of an amalgamation or merger whether or not it otherwise carries the right to vote.

In addition, any minority shareholder receiving notice that the holders of 95% or more of a company’s shares or class of shares intend to compulsorily acquire the minority shareholder’s shares may, within one month of receiving the notice, apply to the Supreme Court of Bermuda to appraise the value of the shares.

Appraisal rights are available under Delaware law for any class or series of common shares of a corporation in a merger or consolidation, subject to limited exceptions, such as a merger or consolidation of corporations listed on a national securities exchange in which listed stock is the offered consideration.

Shareholders’ Suits

Class actions and derivative actions are generally not available to shareholders under Bermuda law. The Bermuda courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company’s memorandum of association or bye-laws.

70

Furthermore, consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud against the minority shareholders or, for instance, where an act requires the approval of a greater percentage of the company’s shareholders than that which actually approved it.

Class actions and derivative actions generally are available to shareholders under Delaware law for, among other things, breach of fiduciary duty, corporate waste and actions not taken in accordance with applicable law. In such actions, the court generally has discretion to permit the winning party to recover attorneys’ fees incurred in connection with such action.

Indemnification of Directors and Officers

Section 98 of the Companies Act provides generally that a Bermuda company may indemnify its directors, officers and auditors against any liability which by virtue of any rule of law would otherwise be imposed on them in respect of any negligence, default, breach of duty or breach of trust, except in cases where such liability arises from fraud or dishonesty of which such director, officer or auditor may be guilty in relation to the company. Section 98 further provides that a Bermuda company may indemnify its directors, officers and auditors against any liability incurred by them in defending any proceedings, whether civil or criminal, in which judgment is awarded in their favor or in which they are acquitted or granted relief by the Supreme Court of Bermuda pursuant to Section 281 of the Companies Act. Section 98 of the Companies Act further provides that a company may advance moneys to an officer or auditor for the costs, charges and expenses incurred by the officer or auditor in defending any civil or criminal proceedings against them, on condition that the officer or auditor shall repay the advance if any allegation of fraud or dishonesty is proved against them.

We have adopted provisions in our Amended and Restated Bye-Laws that provide that we shall indemnify our officers and directors in respect of their actions and omissions except in respect of fraud or dishonesty. Pursuant to our Amended and Restated Bye-Laws, our shareholders have agreed to waive any claim or right of action such shareholder may have, whether individually or by or in our right, against any director or officer on account of any action taken by such director or officer, or the failure of such director or officer to take any action in the performance of his or her duties with or for us or any of our subsidiaries, provided that such waiver does not extend to any matter in respect of any fraud or dishonesty in relation to us which may attach to such director or officer.

Under Delaware law, a corporation may include in its certificate of incorporation a provision that, subject to the limitations described below, eliminates or limits director liability to the corporation or its shareholders for monetary damages for breaches of their fiduciary duty of care. Under Delaware law, a director’s liability cannot be eliminated or limited for: (i) breaches of the duty of loyalty; (ii) acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law; (iii) the payment of unlawful dividends or expenditure of funds for unlawful stock purchases or redemptions; or (iv) transactions from which such director derived an improper personal benefit.

Delaware law provides that a corporation may indemnify a director, officer, employee or agent of the corporation against any liability or expenses incurred in any civil, criminal, administrative or investigative proceeding if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal proceeding, had no reasonable cause to believe their conduct was unlawful, except that in any action brought by or in the right of the corporation, such indemnification may be made only for expenses (not judgments or amounts paid in settlement) and may not be made even for expenses if the officer, director or other person is adjudged liable to the corporation (unless otherwise determined by the court). In addition, under Delaware law, to the extent that a director or officer of a corporation has been successful on the merits or otherwise in defense of any proceeding referred to above, he or she must be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by that party. Furthermore, under Delaware law, a corporation is permitted to maintain directors’ and officers’ insurance.

71

Meeting of Shareholders

The Companies Act requires an annual meeting of shareholders unless waived by resolution of shareholders. Our Amended and Restated Bye-Laws provide that, subject to an election made by us in accordance with the Companies Act to dispense with the holding of annual general meetings, an annual general meeting will be held in each year at such time and place as the Board determines.

Under our Amended and Restated Bye-Laws, a special general meeting of shareholders may be held when the Board, in its judgment, decides such a meeting is necessary. In addition, the Board shall, on the requisition of shareholders holding at the date of the deposit of the requisition not less than 10% of our paid-up share capital, forthwith proceed to convene a special general meeting and the provisions of the Companies Act shall apply.

Delaware law permits the board of directors or any person who is authorized under a corporation’s certificate of incorporation or bylaws to call a special meeting of shareholders.

Notice of Shareholder Meetings

Bermuda law and our Amended and Restated Bye-Laws require that notice of an annual general meeting and special general meeting must be given to each shareholder entitled to attend and vote thereat at least five days before the date of such meeting, stating the date, place and time at which the meeting is to be held and business to be conducted at the meeting, including, for annual general meetings, the election of directors.

A general meeting shall, notwithstanding that it is called on shorter notice than that specified in the Amended and Restated Bye-Laws, be deemed to have been properly called provided that (i) in the case of an annual general meeting, with the agreement of all of the shareholders entitled to attend and vote at such meeting and (ii) in the case of a special general meeting, with the agreement of a majority in number of the shareholders entitled to attend and vote at such meeting, together holding not less than 95% in nominal value of the shares entitled to be voted at such meeting.

The accidental omission to give notice of a general meeting to, or the non-receipt of a notice of a general meeting by, any person entitled to receive notice shall not invalidate the proceedings conducted at such meeting. The Amended and Restated Bye-Laws contain detailed provisions setting out the manner in which a notice of a general meeting must be served effectively on the shareholders.

Under Delaware law, a company is generally required to give written notice of any meeting not less than ten days or more than sixty days before the date of the meeting to each shareholder entitled to vote at the meeting.

Dividends and Other Distributions

Under Bermuda law, a company may not declare or pay a dividend, or make a distribution out of contributed surplus, if there are reasonable grounds for believing that (i) it is, or would after the payment be, unable to pay its liabilities as they become due; or (ii) the realizable value of its assets would thereafter be less than its liabilities. “Contributed surplus” is defined for purposes of Section 54 of the Companies Act to include the proceeds arising from donated shares, credits resulting from the redemption or conversion of shares at less than the amount set up as nominal capital, and donations of cash and other assets to the company.

Under Delaware law, subject to any restrictions contained in the company’s certificate of incorporation, a company may pay dividends out of surplus or, if there is no surplus, out of net profits for the fiscal year in which the dividend is declared and for the preceding fiscal year. Delaware law also provides that dividends may not be paid out of net profits if, after the payment of the dividend, capital is less than the capital represented by the outstanding stock of all classes having a preference upon the distribution of assets.

72

Inspection of Corporate Records

Members of the general public have the right to inspect our public documents available at the office of the Registrar of Companies in Bermuda. These documents include our memorandum of association and any charges on our assets. Our shareholders have the additional right to inspect our Amended and Restated Bye-Laws, minutes of general meetings and audited financial statements, all of which must be presented to the annual general meeting of shareholders.

The register of members of a company is also open to inspection by shareholders and members of the general public without charge. The register of members is required to be open for inspection for not less than two hours in any business day (subject to the ability of a company to close the register of members for not more than 30 days in a year). A company is required to maintain its share register in Bermuda but may, subject to the provisions of the Companies Act, establish a branch register outside of Bermuda. A company is required to keep at its registered office a register of directors and officers and a list of its directors must be filed with the Registrar of Companies where it will be available for public inspection. Bermuda law does not, however, provide a general right for shareholders to inspect or obtain copies of any other corporate records.

Delaware law requires that a company, within ten days before a meeting of shareholders, prepare and make available a complete list of shareholders entitled to vote at the meeting. This list must be open to the examination of any shareholder for any purpose relating to the meeting for a period of at least ten days prior to the meeting, either on a reasonably accessible electronic network or during ordinary business hours at the principal place of business of the company. Delaware law also permits a shareholder to inspect the company’s books and records if the shareholder can establish that he or she is a shareholder of the company, that the shareholder has complied with Delaware law with respect to the form and manner of making demand for inspection of corporate records, and that the inspection by the shareholder is for a proper purpose.

Shareholder Proposals

Under Bermuda law, upon the requisition in writing of such number of shareholders as is hereinafter specified and at their own expense (unless the company otherwise resolves), the company will be required to: (i) give notice to all shareholders entitled to receive notice of the annual general meeting of any resolution which may properly be moved and is intended to be moved at the next annual general meeting; and/or (ii) circulate to all shareholders entitled to receive notice of any general meeting a statement of not more than one thousand words with respect to the matter referred to in any proposed resolution or any business to be conducted at such general meeting. The number of shareholders necessary for a requisition under the foregoing sentence is (x) either any number of shareholders representing not less than 1/20th of the total voting rights of all members having at the date of the requisition a right to vote at that meeting to which the requisition relates; or (y) not less than one hundred shareholders.

Delaware law does not include a provision restricting the manner in which nominations for directors may be made by shareholders or the manner in which business may be brought before a meeting, although restrictions may be included in a Delaware corporation’s certificate of incorporation or bylaws.

Amendment of Memorandum of Association/Certificate of Incorporation

Bermuda law provides that the memorandum of association of a company may be amended by a resolution passed at a general meeting of shareholders of which due notice has been given. Certain amendments to the memorandum of association may require approval of the Bermuda Minister of Finance, who may grant or withhold approval at his or her discretion.

Under Bermuda law, the holders of an aggregate of not less than 20% in par value of a company’s issued share capital have the right to apply to the Bermuda courts for an annulment of any amendment of the memorandum of association adopted by shareholders at any general meeting, other than an amendment which

73

alters or reduces a company’s share capital as provided in the Companies Act. When such an application is made, the amendment becomes effective only to the extent that it is confirmed by the Bermuda court. An application for an annulment of an amendment of the memorandum of association must be made within 21 days after the date on which the resolution altering the company’s memorandum of association is passed and may be made on behalf of persons entitled to make the application by one or more of their designees as such holders may appoint in writing for such purpose. No application may be made by the shareholders voting in favor of the amendment.

Under Delaware law, amendment of the certificate of incorporation, which is the equivalent of a memorandum of association, of a company must be made by a resolution of the board of directors setting forth the amendment, declaring its advisability, and either calling a special meeting of the shareholders entitled to vote or directing that the proposed amendment be considered at the next annual meeting of the shareholders. Delaware law requires that, unless a greater percentage is provided for in the certificate of incorporation, a majority of the outstanding voting power of the corporation is required to approve the amendment of the certificate of incorporation at the shareholders’ meeting. If the amendment would alter the number of authorized shares or par value or otherwise adversely affect the powers, preferences or special rights of any class of a company’s stock, the holders of the issued and outstanding shares of such affected class, regardless of whether such holders are entitled to vote by the certificate of incorporation, are entitled to vote as a class upon the proposed amendment. However, the number of authorized shares of any class may be increased or decreased, to the extent not falling below the number of shares then outstanding, by the affirmative vote of the holders of a majority of the stock entitled to vote, if so provided in the company’s original certificate of incorporation.

Amendment of Bye-Laws

Our Amended and Restated Bye-Laws provide that the Amended and Restated Bye-Laws may be amended upon a resolution approved by a simple majority of the Board and by a resolution approved by a simple majority of the shareholders, provided that any rescission, alteration or amendment to bye-laws conferring special rights on each of the Founders and TFP HoldCo (as described in more detail in Item 19. Exhibits—Exhibit 2.1 Description of Securities of the 2023 Annual Report) shall require the prior consent of each of the Founders and TFP HoldCo for so long as they each beneficially own a specified minimum percentage of our Common Shares or they have a designated director serving on the Board.

Under Delaware law, unless the certificate of incorporation or bylaws provide for a different vote, holders of a majority of the voting power of a corporation and, if so provided in the certificate of incorporation, the directors of the corporation have the power to adopt, amend and repeal the bylaws of a corporation.

Dissolution

Under Bermuda law, a solvent company may be wound up by way of a shareholders’ voluntary liquidation. Prior to the company entering liquidation, a majority of the directors are each required to make a statutory declaration, which states that the directors have made a full inquiry into the affairs of the company and have formed the opinion that the company will be able to pay its debts within a period of 12 months of the commencement of the winding-up and must file the statutory declaration with the Registrar of Companies in Bermuda. The general meeting is required to be convened primarily for the purposes of passing a resolution that the company be wound up voluntarily and appointing a liquidator. The winding-up of the company is deemed to commence at the time of the passing of the resolution.

Under Delaware law, a corporation may voluntarily dissolve (i) if a majority of the board of directors adopts a resolution to that effect and the holders of a majority of the issued and outstanding shares entitled to vote thereon vote for such dissolution; or (ii) if all shareholders entitled to vote thereon consent in writing to such dissolution.

74

SHARES ELIGIBLE FOR FUTURE SALE

General

Future sales of substantial amounts of our Common Shares in the public market, or the perception that such sales may occur, could adversely affect the prevailing market price of our Common Shares or impair our ability to raise equity capital in the future. No prediction can be made as to the effect, if any, future sales of our Common Shares, or the availability of our Common Shares for future sales, will have on the market price of our Common Shares prevailing from time to time. The sale of substantial amounts of our Common Shares in the public market, or the perception that such sales of our Common Shares could occur, could adversely affect the prevailing market price of our Common Shares.

Sales of Restricted Securities

A total of 116,898,062 of our Common Shares were outstanding as of May 17, 2024. The Selling Shareholders are offering 9,000,000 Common Shares (or 10,350,000 Common Shares if the underwriters exercise their option to purchase additional Common Shares from the Selling Shareholders in full). After giving effect to the offering, 52,575,139 (or 53,685,686 Common Shares if the underwriters exercise their option to purchase additional Common Shares from the Selling Shareholders in full) will be freely tradable without restriction under the Securities Act, unless purchased by our “affiliates,” as that term is defined in Rule 144 under the Securities Act. The remaining Common Shares that will be outstanding after this offering are “restricted securities” within the meaning of Rule 144 under the Securities Act. Restricted securities may be sold in the public market only if registered under the Securities Act or if they qualify for an exemption from registration, including an exemption under Rule 144, Rule 701 or Regulation S, which are summarized below.

Of the 116,898,062 Common Shares outstanding immediately following this offering, 53.81% of our Common Shares (or 52.59% of our Common Shares if the underwriters exercise their option to purchase additional Common Shares from the Selling Shareholders in full) are subject to lock-up agreements as described herein. See “—Lock-up Agreement” and “—IPO Assistance and Lock-Up Agreement.”

As defined in Rule 144, an “affiliate” of an issuer is a person that directly, or indirectly through one or more intermediaries, controls, is controlled by or is under common control with the issuer.

Lock-up Agreement

Prior to the settlement of this offering, we and the Selling Shareholders, have agreed, subject to limited exceptions, not to offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase or otherwise dispose of, directly or indirectly, or enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Shares or such other securities for a period of 90 days after the date of this prospectus. These agreements are described below under the section captioned “Underwriting.”

IPO Assistance and Lock-Up Agreement

In connection with our initial public offering, Daniel Burrows, Allan Decleir, Denise Brown-Branch and Ian Houston (collectively, the “Insurance Group Executives” and each, an “Insurance Group Executive”), Richard Brindle, Richard Coulson, Hinal Patel and Charles Mathias (collectively, the “TFP Executives” and each, a “TFP Executive”) and FIHL entered into an initial public offering assistance and lock-up agreement (the “IPO Assistance and Lock-Up Agreement”). Under the terms of the IPO Assistance and Lock-Up Agreement, (i) the TFP Executives and Daniel Burrows agreed, subject to limited exceptions, not to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or

75

warrant to purchase, lend, assign, encumber, pledge, hypothecate, or otherwise transfer or dispose of, directly or indirectly, any of their Common Shares for a period of 18 months following the effective date of our initial public offering, except that 25% of such Common Shares relating to Retention RSUs (as defined below) are released from such lock-up within 180 days after such date of vesting and (ii) the Insurance Group Executives agreed, subject to limited exceptions, not to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, assign, encumber, pledge, hypothecate, or otherwise transfer or dispose of, directly or indirectly, any of the Common Shares that they receive following the vesting of their retention restricted stock units approved by FIHL on May 15, 2023 (the “Retention RSUs”) for a period of 18 months after the date of vesting of such Retention RSUs (such period end date being October 1, 2025), except that 25% of such Common Shares relating to Retention RSUs are released from such lock-up within 180 days after such date of vesting. We have agreed not to waive or amend certain provisions of the IPO Assistance and Lock-Up Agreement for a period of 90 days after the date of this prospectus, with respect to certain of our directors and officers.

Registration Rights

Certain shareholders have the right to require us to include their Registrable Securities in any registration statement filed for the purposes of a public offering of our equity securities, subject to the terms of the Registration Rights Agreement. These Registrable Securities will represent 55.025% of our outstanding Common Shares after this offering (or 54.075% if the underwriters exercise their option to purchase additional Common Shares from the Selling Shareholders in full). See Item 7. Major Shareholders and Related Party Transactions—B. Related Party Transactions—Registration Rights Agreement of the 2023 Annual Report.

Rule 144

In general, under Rule 144 as currently in effect, beginning 90 days after the effectiveness of the registration statement of which this prospectus forms a part, a person who is not our affiliate and has not been our affiliate at any time during the preceding three months will be entitled to sell any of our Common Shares that such person has beneficially owned for at least six months, including the holding period of any prior owner other than one of our affiliates, without regard to volume limitations and subject only to the availability of current public information about us. A non-affiliated person who has beneficially owned Common Shares considered to be restricted securities under Rule 144 for at least one year would be entitled to sell such Common Shares without complying with any of the requirements of Rule 144.

Beginning 90 days after the effectiveness of the registration statement of which this prospectus forms a part, an affiliate of ours who has beneficially owned our Common Shares for at least six months would be entitled to sell, within any three-month period, a number of Common Shares that does not exceed the greater of:

Sales under Rule 144 by our affiliates or persons selling our Common Shares on behalf of our affiliates are also subject to any manner of sale provisions, notice requirements and the availability of current public information about us. The sale of these Common Shares, or the perception that sales will be made, could adversely affect the price of our Common Shares after this offering because a great supply of Common Shares would be, or would be perceived to be, available-for-sale in the public market.

We are unable to estimate the number of Common Shares that will be sold under Rule 144 since this will depend on the market price for our Common Shares, the personal circumstances of the shareholder and other factors.

76

Rule 701

Any of our employees, officers or directors who acquired our Common Shares under a written compensatory plan or contract may be entitled to sell them in reliance on Rule 701. Rule 701 permits affiliates to sell their Rule 701 Common Shares under Rule 144 without complying with the holding period requirements of Rule 144. Rule 701 further provides that non-affiliates may sell these Common Shares in reliance on Rule 144 without complying with the holding period, public information, volume limitation or notice provisions of Rule 144. All holders of Rule 701 Common Shares are required to wait until 90 days after the date of this prospectus before selling such Common Shares. However, our Common Shares issued under Rule 701 that are subject to lock-up agreements will become eligible for sale only when the 90-day lock-up agreements expire.

The SEC has indicated that Rule 701 will apply to typical stock options granted by an issuer before it becomes subject to the reporting requirements of the Exchange Act, along with the shares acquired upon exercise of such options, including exercises after a company becomes subject to the reporting requirements of the Exchange Act.

Regulation S

Regulation S under the Securities Act provides an exemption from registration requirements in the U.S. for offers and sales of securities that occur outside the U.S. Rule 903 of Regulation S provides the conditions to the exemption for a sale by an issuer, a distributor, their respective affiliates or anyone acting on their behalf, while Rule 904 of Regulation S provides the conditions to the exemption for a resale by persons other than those covered by Rule 903. In each case, any sale must be completed in an offshore transaction, as that term is defined in Regulation S, and no directed selling efforts, as that term is defined in Regulation S, may be made in the U.S.

We are a “foreign issuer” as defined in Regulation S. As a foreign issuer, securities that we sell outside the U.S. pursuant to Regulation S are not considered to be restricted securities under the Securities Act, and, subject to the offering restrictions imposed by Rule 903, are freely tradable without registration or restrictions under the Securities Act, unless the securities are held by our affiliates. Generally, subject to certain limitations, a holder of our restricted securities who is not our affiliate or who is an affiliate by virtue of his status as an officer or director may, under Regulation S, resell his restricted securities in an “offshore transaction” if none of the seller or its affiliates or any person acting on their behalf engages in directed selling efforts in the U.S. and, in the case of a sale of our restricted securities by an officer or director who is an affiliate of ours solely by virtue of holding such position, no selling commission, fee or other remuneration is paid in connection with the offer or sale other than the usual and customary broker’s commission that would be received by a person executing such transaction as agent. Additional restrictions are applicable to a holder of our restricted securities who will be an affiliate of FIHL other than by virtue of his or her status as an officer or director of FIHL.

Form S-8 Registration Statement

On July 3, 2023, we filed a registration statement on Form S-8 with the SEC, which became effective upon filing, to register 4,913,119 Common Shares issuable under our Long-Term Incentive Plan. 479,245 restricted stock units vested on April 1, 2024, resulting in the issuance of 367,878 Common Shares. As of May 17, 2024 there are no Common Shares issuable (that are not already issued) as a result of vested restricted stock units then outstanding under our Long-Term Incentive Plan. Accordingly, the Common Shares registered under such registration statement are available for sale in the open market following the effective date, unless such Common Shares are subject to vesting restrictions with us, Rule 144 restrictions applicable to our affiliates or the lock-up restrictions described herein, if applicable.

Certain U.S. Tax Consequences

The following legal discussion (including and subject to the matters and qualifications set forth in such summary) is based upon the advice of Willkie Farr & Gallagher LLP. The advice of such firm does not include any factual or accounting matters, determinations or conclusions, including amounts and computations of RPII and amounts of components thereof or facts relating to Fidelis Insurance Group’s business or activities. The tax treatment of a holder of Common Shares, or of a person treated as a holder of Common Shares for U.S. federal income, state, local or non-U.S. tax purposes, may vary depending on the holder’s particular tax situation. Statements contained herein as to the beliefs, expectations and conditions of FIHL and its subsidiaries as to the application of such tax laws or facts represent the view of management as to the application of such laws and do not represent the opinions of counsel.

PROSPECTIVE INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS WITH RESPECT TO THEIR PARTICULAR CIRCUMSTANCES CONCERNING THE U.S. FEDERAL, STATE, LOCAL AND NON-U.S. TAX CONSEQUENCES OF OWNING COMMON SHARES.

U.S. Tax Reform

The 2017 Act was passed by the U.S. Congress and signed into law on December 22, 2017, with certain provisions intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the United States, but have certain U.S. connections, and U.S. Persons (as defined below) investing in such companies. Among other things, the 2017 Act revised the rules applicable to PFICs and CFCs in ways that could affect the timing or amount of U.S. federal income taxes imposed on certain investors that are U.S. Persons. Further, it is possible that other legislation could be introduced and enacted by the current Congress or future Congresses that could have an adverse impact on Fidelis Insurance Group, Fidelis Insurance Group’s operations or U.S. Holders. Additionally, tax laws and interpretations regarding whether a company is engaged in a U.S. trade or business or whether a company is a CFC or a PFIC or has RPII are subject to change, possibly on a retroactive basis. The U.S. Treasury Department recently issued final and proposed regulations intended to clarify the application of the insurance income exception to the classification of a non-U.S. insurer as a PFIC and provide guidance on a range of issues relating to PFICs, and recently issued proposed regulations that would expand the scope of the RPII rules. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming as well. FIHL cannot be certain if, when, or in what form such regulations or pronouncements may be provided and whether such guidance will have a retroactive effect.

U.S. Taxation of Fidelis Insurance Group

The following discussion is a summary of material U.S. federal income tax considerations relating to Fidelis Insurance Group’s operations. A non-U.S. corporation that is engaged in the conduct of a U.S. trade or business will be subject to U.S. federal income tax as described below, unless entitled to the benefits of an applicable tax

78

treaty. Whether a trade or business is being conducted in the U.S. is an inherently factual determination. Because the Code, regulations and court decisions fail to identify definitively activities that constitute being engaged in a trade or business in the U.S., FIHL cannot be certain that the IRS will not contend successfully that it or any of its non-U.S. subsidiaries are or will be engaged in a trade or business in the U.S. A non-U.S. corporation deemed to be so engaged would be subject to U.S. income tax at regular corporate rates, as well as the branch profits tax, on its income which is treated as effectively connected with the conduct of that trade or business unless the corporation is entitled to relief under the permanent establishment provision of an applicable tax treaty, as discussed below. Such income tax on effectively connected income, if imposed, would be computed in a manner generally analogous to that applied to the income of a U.S. corporation, except that a non-U.S. corporation is generally entitled to deductions and credits only if it timely files a U.S. federal income tax return. Each of FIHL, FIBL, FIID, FIHL (UK) Services, Fidelis European Holdings Limited and FUL files protective U.S. federal income tax returns on a timely basis in order to preserve the right to claim income tax deductions and credits if it is ever determined that it is subject to U.S. federal income tax. The highest marginal federal income tax rates currently are 21% for a corporation’s effectively connected income and 30% for the additional “branch profits” tax. In addition, certain corporations with effectively connected income may be subject to a corporate alternative minimum tax of 15 percent of the corporation’s adjusted financial statement income.

If FIBL is entitled to the benefits under the income tax treaty between Bermuda and the U.S. (the “Bermuda Treaty”), FIBL would not be subject to U.S. income tax on any income found to be effectively connected with a U.S. trade or business unless that trade or business is conducted through a permanent establishment in the U.S. Similarly, if FIHL or any U.K. subsidiary of FIHL is entitled to the benefits under the U.S. income tax treaty with the U.K. (the “U.K. Treaty”) (discussed below), it would not be subject to U.S. income tax on any income found to be effectively connected with U.S. trade or business unless that trade or business is conducted through a permanent establishment in the U.S. FIBL, FIHL and the U.K. subsidiaries of FIHL each currently intend to conduct their activities so that they do not have a permanent establishment in the U.S., although FIHL cannot be certain that this result will be achieved.

An insurance enterprise resident in Bermuda generally will be entitled to the benefits of the Bermuda Treaty if (i) more than 50% of its shares are owned beneficially, directly or indirectly, by individual residents of the U.S. or Bermuda or U.S. citizens; and (ii) its income is not used in substantial part, directly or indirectly, to make disproportionate distributions to, or to meet certain liabilities of, persons who are neither residents of either the U.S. or Bermuda nor U.S. citizens. No regulations interpreting the Bermuda Treaty have been issued. FIHL cannot be certain that FIBL will be eligible for Bermuda Treaty benefits because of factual and legal uncertainties regarding the residency and citizenship of the company’s shareholders. Accordingly, FIBL intends to conduct substantially all of its operations outside the U.S. and to limit its U.S. contacts so that FIBL would not be treated as engaged in the conduct of a trade or business in the U.S.

Under the U.K. Treaty, a U.K. resident company is entitled to the benefits of the treaty only if certain requirements can be satisfied, for example where: (i) the principal class of its shares is listed or admitted to dealings on certain recognized stock exchanges and is regularly traded on one or more recognized stock exchanges, (ii) shares representing at least 50 percent of the aggregate voting power and value of such company are owned directly or indirectly by five or fewer companies entitled to the benefits of the U.K. Treaty, (iii) such company is owned more than 50 percent, by vote and by value, by “qualified persons” (broadly speaking, certain U.S. and U.K. tax residents) during a requisite portion of the relevant taxable period, or (iv) such company is engaged in the active conduct of a trade or business in the U.K. and the income, profit or gain derived from the United States is derived in connection with, or is incidental to, that trade or business, and the company satisfies certain other conditions. Provided that FIHL is successfully listed and regularly traded on the NYSE and its U.K. subsidiaries successfully carry out their intended business plan, each such entity expects to qualify for benefits under the U.K. Treaty, although FIHL cannot be certain it will achieve this result. If each of FIHL and its U.K. subsidiaries qualifies for treaty benefits, each of FIHL and its U.K. subsidiaries should be subject to U.S. federal income tax on its income found to be effectively connected with a U.S. trade or business only if such income is attributable to the conduct of a trade or business carried on through a permanent establishment in the U.S. FIHL

79

and its U.K. subsidiaries have conducted and intend to conduct their activities in a manner so that none of them should have a permanent establishment in the U.S., although FIHL cannot be certain that they will achieve this result.

Under the U.K. Treaty, the additional U.S. branch profits tax may be imposed at a rate of up to five percent (5%) absent an applicable exception to the extent a U.K. resident company has a permanent establishment in the U.S.

Non-U.S. insurance companies carrying on an insurance business within the U.S. have a certain minimum amount of effectively connected net investment income, determined in accordance with a formula that depends, in part, on the amount of U.S. risk insured or reinsured by such companies. If FIBL or FUL is considered to be engaged in the conduct of an insurance business in the U.S. and it is not entitled to the benefits of an income tax treaty with the U.S. in general, the Code could subject a significant portion of FIBL or FUL’s investment income to U.S. income tax. In addition, while the Bermuda Treaty clearly applies to premium income, it is uncertain whether the Bermuda Treaty applies to other income such as investment income. If FIBL is considered engaged in the conduct of an insurance business in the U.S. and is entitled to the benefits of the Bermuda Treaty in general, but the Bermuda Treaty is interpreted to not apply to investment income, a significant portion of FIBL’s investment income could be subject to U.S. income tax.

Non-U.S. corporations not engaged in a trade or business in the U.S. are nonetheless subject to U.S. income tax imposed by withholding on certain “fixed or determinable annual or periodic gains, profits and income” derived from sources within the U.S. (such as dividends and certain interest on investments), subject to exemption under the Code or reduction by applicable treaties. Generally, under the U.K. Treaty the withholding rate is reduced (i) on dividends from less than ten percent (10%) owned corporations to 15%; (ii) on dividends from 10% or more owned corporations to five percent (5%) (and is eliminated in some cases); and (iii) on interest to zero percent (0%). The Bermuda Treaty does not reduce the U.S. withholding rate on U.S.-sourced investment income.

The U.S. also imposes FET on insurance premiums paid to non-U.S. insurers with respect to (i) risks of a U.S. entity or individual, located wholly or partly within the U.S. and (ii) risks of a non-U.S. entity or individual engaged in trade or business in the U.S., located within the U.S. (“U.S. Situs Risks”) and on reinsurance premiums for any reinsurance policy covering any such risks. The rates of FET applicable to premiums paid are four percent (4%) for direct property and casualty insurance premiums and one percent (1%) for reinsurance premiums or life insurance premiums, subject to elimination pursuant to a U.S. income tax treaty. The U.K. Treaty provides for the elimination of the FET on insurance or reinsurance premiums paid to U.K. residents, otherwise entitled to the benefits of the treaty, with respect to U.S. Situs Risks, provided that the U.K. resident does not cede the risks in a transaction characterized as part of a conduit arrangement for purposes of the U.K. Treaty. If FUL is entitled to the benefit of the FET exemption in the U.K. Treaty, but it cedes business with respect to U.S. Situs Risks in transactions that are characterized as conduit arrangements for purposes of the U.K. Treaty, it would not be entitled to the U.K. Treaty FET exemption with respect to these U.S. Situs Risks. The Bermuda Treaty does not eliminate the FET on premiums ceded to Bermuda residents with respect to U.S. Situs Risks.

Bermuda Taxation

Taxation of FIHL and FIBL

In response to the OECD Pillar Two initiative, Bermuda has enacted the Corporate Income Tax Act 2023 (“CIT Act”) the provisions of which will be fully effective for tax years beginning on or after January 1, 2025. Entities subject to tax under the CIT Act are the Bermuda constituent entities of multi-national groups. A multi-national group is defined under the CIT Act as a group with entities in more than one jurisdiction with consolidated revenues of at least €750 million for two of the four previous fiscal years. If Bermuda constituent entities of a multi-national group are subject to tax under the CIT Act, such tax is charged at a rate of 15 per cent

80

of the net income of such constituent entities (as determined in accordance with the CIT Act, including after adjusting for any relevant foreign tax credits applicable to the Bermuda constituent entities).

On the basis of the foregoing, we have concluded that the CIT Act will apply to our Bermuda constituent entities (i.e. Bermuda tax resident entities and Bermuda permanent establishments) and in recognition of the transitional provisions under the CIT Act in respect of pre-commencement periods FIBL, as a Bermuda constituent entity, has recognized a deferred tax asset of $90 million.

For so long as FIHL is UK tax resident, the CIT Act will only apply to FIHL to the extent that FIHL maintains a Bermuda permanent establishment, and only then in respect of such financial accounting net income or loss as is allocated to the Bermuda permanent establishment in accordance with US GAAP (on the basis that this is the accounting standard used in the preparation of the consolidated accounts of FIHL). In any event, tax under the CIT Act only arises in respect of tax years starting on or after January 1, 2025.

At the present time, there is no other Bermuda income or profits tax, withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by FIHL or FIBL in respect of the Common Shares. FIHL has obtained an assurance from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act 1966 (the “EUTP Act”) that, in the event that any legislation is enacted in Bermuda imposing any tax computed on profits or income, or computed on any capital asset, gain or appreciation or any tax in the nature of estate duty or inheritance tax, such tax will not, until March 31, 2035, be applicable to us or to any of our operations or to the Common Shares, debentures or other obligations except insofar as such tax applies to persons ordinarily resident in Bermuda or is payable by FIHL in respect of real property owned or leased by it in Bermuda. The same assurance has been obtained with respect to FIBL. Given the limited duration of any assurance by the Minister of Finance, neither FIHL nor FIBL can be certain that it will not be subject to any Bermuda taxes after March 31, 2035. In particular, in the event that FIHL and FIBL are subject to tax under the CIT Act, this would supersede the assurances received from the Minister of Finance under the EUTP Act. Each of FIHL and FIBL pays an annual Bermuda Government fee and an insurance license fee, as applicable. In addition, all entities employing individuals in Bermuda are required to pay a payroll tax and there are other sundry taxes payable, directly or indirectly, to the Bermuda Government.

Pursuant to the Payroll Tax Act 1995 and the Payroll Tax Rates Act 1995 of Bermuda (together, the “Payroll Tax Act”), an employer is required to pay payroll tax on remuneration paid by it to each employee or deemed employee for services rendered by the employee or deemed employee during that tax period wholly or mainly in Bermuda (provided that any remuneration paid by the employer to the employee or deemed employee in excess of $900,000 per annum is disregarded) and may, within certain parameters, make deductions from remuneration paid to each employee and deemed employee in each tax period in respect of a certain portion of the payroll tax paid by the employer in respect of that employee or deemed employee in that tax period. For the purposes of the Payroll Tax Act, any gain obtained by the exercise, assignment or release of any option awarded under any of our option plans will constitute actual remuneration.

In addition, the OECD has published reports and launched a global dialogue among member and non-member countries on measures to limit harmful tax competition. These measures are largely directed at counteracting the effects of tax havens and preferential tax regimes in countries around the world. According to the OECD, Bermuda is a jurisdiction that has substantially implemented the internationally agreed tax standard. However, neither FIHL nor FIBL is able to predict whether any changes will be made to this classification or whether any such changes will subject FIHL or FIBL to additional taxes.

Taxation of Shareholders

In the event any shareholder is determined to be Bermuda constituent entities of a multi-national group, they may also be subject to tax under the CIT Act. At the present time, there is no other Bermuda income or profits tax, withholding tax, capital gains tax, capital transfer tax, estate duty or inheritance tax payable by our shareholders in respect of our Common Shares.

UNDERWRITING

Under the terms and subject to the conditions in an underwriting agreement dated as of the date of this prospectus, the underwriters named below, for whom Barclays Capital Inc., J.P. Morgan Securities LLC, and Goldman Sachs & Co. LLC are acting as representatives, have severally agreed to purchase, and the Selling Shareholders have agreed to sell to them, the number of Common Shares indicated below:

The underwriting agreement provides that the obligations of the underwriters are subject to certain conditions precedent, including the absence of any material adverse change in our business and the receipt of certain certificates, opinions and letters from us, our counsel and the independent auditors. The underwriters have committed to purchase all of the Common Shares offered by the Selling Shareholders if any such Common Shares are purchased. However, the underwriters are not required to take or pay for the Common Shares covered by their option to purchase additional Common Shares described below. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated. The offering of the Common Shares by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

The underwriters propose to offer the Common Shares directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers at a price that represents a concession not in excess of $       per Common Share under the public offering price. After the offering of the Common Shares, the offering price and other selling terms may from time to time be varied by the representatives.

The Selling Shareholders have granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to 1,350,000 additional Common Shares at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional Common Shares as the number listed next to the underwriter’s name in the preceding table bears to the total number of Common Shares listed next to the names of all underwriters in the preceding table.

The following table shows the per Common Share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to the Selling Shareholders. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 1,350,000 Common Shares from the Selling Shareholders. We are not selling any Common Shares in this offering and will not receive any of the proceeds from the Common Shares sold by the Selling Shareholders.

82

We have agreed that, without the prior written consent of Barclays Capital Inc., J.P. Morgan Securities LLC, and Goldman Sachs & Co. LLC on behalf of the underwriters, we will not, and will not publicly disclose an intention to, during the period ending 90 days after the date of this prospectus (the “restricted period”):

The restrictions described above do not apply to;

Additionally, the Selling Shareholders have agreed that, without the prior written consent of Barclays Capital Inc., J.P. Morgan Securities LLC, and Goldman Sachs & Co. LLC on behalf of the underwriters, they will not, and will not publicly disclose an intention to, during the restricted period:

83

The restrictions described in the immediately preceding paragraph do not apply to certain transfers, dispositions or transactions, including:

Barclays Capital Inc., J.P. Morgan Securities LLC, and Goldman Sachs & Co. LLC, in their sole discretion, may release the Common Shares and other securities subject to the lock-up agreements described above in whole or in part at any time. When determining whether or not to release common stock and other securities from lock-up agreements, Barclays Capital Inc. will consider, among other factors, the holder’s reasons for requesting the release, the Common Shares and other securities for which the release is being requested and market conditions at the time.

84

We have agreed not to waive or amend certain provisions of the IPO Assistance and Lock-Up Agreement, with respect to certain of our directors and officers, or consent to any request by TFP HoldCo to offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend or otherwise dispose of, directly or indirectly, any of our common shares for a period of 90 days after the date of this prospectus, subject to the Repurchase Election under the Amended and Restated Common Shareholders Agreement.

In order to facilitate the offering of the Common Shares, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Shares. Specifically, the underwriters may sell more Common Shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of Common Shares available for purchase by the underwriters by exercise of their option to purchase additional Common Shares. The underwriters can close out a covered short sale by exercising their option to purchase additional Common Shares or purchasing Common Shares in the open market. In determining the source of Common Shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of Common Shares compared to the price available under their option to purchase additional Common Shares. The underwriters may also sell Common Shares in excess of their option to purchase additional Common Shares, creating a naked short position. The underwriters must close out any naked short position by purchasing Common Shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Common Shares in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, Common Shares in the open market to stabilize the price of the Common Shares. These activities may raise or maintain the market price of the Common Shares above independent market levels or prevent or retard a decline in the market price of the Common Shares. The underwriters are not required to engage in these activities and may end any of these activities at any time.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $1.4 million. We have agreed to reimburse the underwriters for certain of their expenses in an amount up to $35,000.

We, the Selling Shareholders and the underwriters have agreed to indemnify one and another against certain liabilities, including liabilities under the Securities Act.

Our Common Shares are listed on the NYSE under the symbol “FIHL.”

A prospectus in electronic format may be made available on websites maintained by one or more underwriters, or selling group members, if any, participating in this offering. The representatives may agree to allocate a number of Common Shares to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. Certain of the underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory and investment banking services for us, for which they received or will receive customary fees and expenses. In particular, affiliates of Barclays Capital Inc., BMO Capital Markets Corp. and Citigroup Global Markets Inc. provide letters of credit facilities to us. In addition, affiliates of Goldman Sachs & Co. LLC provide services in relation to the Share Repurchase Program. Affiliates of Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC provide asset- and investment management services.

In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts

85

of their customers and may at any time hold long and short positions in such securities and instruments. Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Selling Restrictions

European Economic Area

In relation to each member state of the European Economic Area (each an “EEA State”), no Common Shares have been offered or will be offered pursuant to the offering to the public in that EEA State prior to the publication of a prospectus in relation to our Common Shares which have been approved by the competent authority in that EEA State or, where appropriate, approved in another EEA State and notified to the competent authority in that EEA State, all in accordance with the E.U. Prospectus Regulation, except that offers of our Common Shares may be made to the public in that EEA State at any time under the following exemptions under the E.U. Prospectus Regulation:
