• changes in relationships with important parties in our product distribution network;

• the activities of our competitors and our ability to grow our retail business in a highly competitive environment;

• the accuracy of our estimates regarding the future performance of our investment portfolio;

• increased regulation or scrutiny of alternative investment advisers and certain trading methods;

• certain of our non-United States (US) subsidiaries becoming subject to US federal income taxation in amounts greater than expected;

PROSPECTUS SUPPLEMENT SUMMARY

The information below is only a summary of more detailed information included elsewhere in or incorporated by reference in this prospectus supplement and the accompanying prospectus. This summary may not contain all the information that is important to you or that you should consider before making a decision to invest in the notes in this offering. The other information is important, so please read this entire prospectus supplement and the accompanying prospectus, as well as the information incorporated by reference herein and therein carefully.

Our Company

We are a leading financial services company that specializes in issuing, reinsuring and acquiring retirement savings products designed for the increasing number of individuals and institutions seeking to fund retirement needs. We generate attractive financial results for our policyholders and shareholders by combining our two core competencies of (1) sourcing long-term, persistent liabilities and (2) using the global scale and reach of Apollo’s asset management business to actively source or originate assets with our preferred risk and return characteristics. Our investment philosophy is to invest a portion of our assets in securities that earn an incremental yield by taking measured liquidity and complexity risk and capitalize on our long-dated funding profile to prudently achieve higher net investment earned rates, rather than assuming incremental credit risk. Our differentiated investment strategy benefits from our relationship with Apollo, which provides a full suite of services for our investment portfolio, including direct investment management, asset allocation, mergers and acquisitions asset diligence and certain operational support services, including investment compliance, tax, legal and risk management support. Our relationship with Apollo provides us with access to Apollo’s investment professionals around the world as well as Apollo’s global asset management infrastructure across a broad array of asset classes. We are led by a highly skilled management team with extensive industry experience. Our headquarters are located in West Des Moines, Iowa. Effective January 1, 2022, as a result of the closing of the merger involving us and Apollo, AGM (NYSE: APO) became the beneficial owner of 100% of our common stock and controls all of the voting power to elect members to our board of directors.

The issuer is a holding company for its insurance subsidiaries and does not have any significant operations of its own. The principal sources of cash to meet the issuer’s obligations are dividends, returns of capital, loans or advances or other intercompany transfers of funds from its subsidiaries. The issuer’s insurance subsidiaries are subject to regulatory restrictions on the payment of dividends imposed by the regulators of their respective domiciles. The dividend limitation for Bermuda insurance and reinsurance subsidiaries is based on the statutory capital and surplus as of the immediately preceding calendar year. The dividend limitation for U.S. insurance subsidiaries is based on the surplus to policyholders as of the immediately preceding calendar year and statutory net gain from operations of the immediately preceding calendar year.

The issuer is a corporation organized under the laws of the State of Delaware. Our principal executive offices are located at 7700 Mills Civic Pkwy, West Des Moines, Iowa 50266, and our telephone number is 515-342-4678. Our website address is www.athene.com. Information contained on our website or connected thereto does not constitute a part of, and is not incorporated by reference into, this prospectus supplement or the accompanying prospectus.

S-3

RISK FACTORS

Investing in the notes involves a high degree of risk. In addition to the other information contained in this prospectus supplement, in the accompanying prospectus and in documents that we incorporate by reference herein and therein, you should carefully consider the risks discussed below before making a decision about investing in our notes. The risks and uncertainties discussed below are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. If any of these risks occur, our business, financial condition and operating results could be materially adversely affected, the trading price of our notes could decline and you could lose part or all of your investment. The following should be read in conjunction with, and supplements and amends, as applicable, the factors that may affect our business or operations described in Part I—Item 1A. Risk Factors of our Annual Report.

Risks Related to the Notes

The notes are effectively subordinated to our secured debt and any liabilities of our subsidiaries.

The notes will rank senior in right of payment to any of AHL’s indebtedness that is expressly subordinated in right of payment to the notes, equal in right of payment to any of AHL’s liabilities that are not so subordinated, effectively junior in right of payment to any of AHL’s secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all indebtedness and other liabilities (including interest sensitive contract liabilities, future policy benefits, market risk benefits and other payables) of AHL’s subsidiaries. In the event of AHL’s bankruptcy, liquidation, reorganization or other winding up, AHL’s assets that secure debt ranking senior or equal in right of payment to the notes will be available to pay obligations on the notes only after the secured debt has been repaid in full from these assets. There may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding. The indenture governing the notes will not prohibit us from incurring additional senior debt or secured debt, nor does it prohibit any of AHL’s subsidiaries from incurring additional liabilities. The notes will not be obligations of, or guaranteed by, AGM or any entity other than AHL.

As of December 31, 2023, AHL had $4.3 billion of unsecured senior indebtedness and other liabilities, $1.25 billion of availability under its $1.25 billion unsecured revolving credit facility, and $2.6 billion of availability under its $2.6 billion unsecured revolving liquidity facility. As of December 31, 2023, AHL’s subsidiaries had $275 billion of indebtedness and other liabilities (including interest sensitive contract liabilities, future policy benefits, market risk benefits and other payables, but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP) to which the notes would have been structurally subordinated.

The issuer is a holding company with limited operations of its own. As a consequence, our ability to make payments in connection with the notes will depend on the ability of our subsidiaries to make distributions or other payments to us, which may be restricted by law.

The issuer is a holding company with limited business operations of its own. The notes will not be obligations of, or guaranteed by, AGM or any entity other than the issuer. Our primary subsidiaries are insurance and reinsurance companies that own substantially all of our assets and conduct substantially all of our operations. Accordingly, AHL’s ability to make timely payments on its debt obligations, including the notes, is dependent, to a significant extent, on the generation of cash flow by its subsidiaries and their ability to make such cash or other assets available to AHL, by dividend or otherwise. Dividends or distributions that may be paid by our insurance subsidiaries to us are limited or restricted by applicable insurance or other laws that are based in part on the prior year’s statutory income and surplus, or other sources. See “—Risks Relating to Insurance and Other Regulatory Matters—Our industry is highly regulated and we are subject to significant legal restrictions and these restrictions may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects” in “Item 1A—Risk Factors” in our Annual Report.

S-4

Certain of our subsidiaries may not be able to, or may not be permitted to, make distributions to enable us to meet our obligations and pay dividends. Each subsidiary is a distinct legal entity and legal and contractual restrictions may also limit our ability to obtain cash from our subsidiaries. In addition to the restrictions described above, our subsidiaries, as members of our insurance holding company system, are subject to various statutory and regulatory restrictions on their ability to pay dividends to us, as further described under “Item 1.— Business—Regulation—Restrictions on Dividends and Other Distributions” in our Annual Report.

Servicing our debt requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial debt.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations.

Despite our debt levels after giving effect to the issuance of the notes, we may still incur substantially more debt or take other actions which would intensify the risks discussed above.

Despite our consolidated debt levels after giving effect to the issuance of the notes, we and our subsidiaries may be able to incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. We will not be restricted under the terms of the indenture governing the notes from incurring additional debt, securing existing or future debt, recapitalizing our debt or taking a number of other actions that are not limited by the terms of the indenture governing the notes that could have the effect of diminishing our ability to make payments on the notes when due.

The notes are protected by only limited restrictive covenants.

The indenture governing the notes will not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness or the issuance or repurchase of securities by us or any of our subsidiaries. The indenture will not contain any covenants or other provisions to afford protection to holders of the notes in the event of a fundamental change or other corporate transaction involving us except to the extent described under “Description of the Senior Notes—Restrictive Covenants—Consolidation, Merger, Sale of Assets and Other Transactions.”

We cannot assure you that an active trading market will develop for the notes.

Prior to this offering, there has been no trading market for the notes, and we do not intend to apply to list the notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. We have been informed by the underwriters that they intend to make a market in the notes after the offering is completed. However, the underwriters may cease their market-making at any time without notice. In addition, the liquidity of the trading market in the notes, and the market price quoted for the notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result, we cannot assure you that an active trading market will develop for the notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the notes may be adversely affected. In that case you may not be able to sell your notes at a particular time or you may not be able to sell your notes at a favorable price.

S-5

Any adverse rating of the notes may cause their trading price to fall.

We intend to seek a rating on the notes from one or more rating services. If a rating service that rates the notes were to lower its rating on the notes below the rating initially assigned to the notes or otherwise announces its intention to put the notes on credit watch, the trading price of the notes could decline.

The ratings of our securities, including the notes, may be downgraded.

We have sought to obtain ratings for the notes. However, if any ratings are assigned to the notes in the future or if we issue other securities with a rating, such ratings, if they are lower than market expectations or are subsequently lowered or withdrawn, could adversely affect the market for or the market value of the notes. In addition, a future lowering or withdrawal of our corporate family rating, claims-paying rating or rating of any of our outstanding indebtedness could adversely affect the market value of our debt securities, including the notes. A rating is not a recommendation to purchase, sell or hold any particular security, including the notes. Ratings do not reflect market prices or suitability of a security for a particular investor and any future rating of the notes may not reflect all risks related to us and our business, or the structure or market value of the notes. Ratings only reflect the views of the rating agency or agencies issuing the ratings and such ratings could be revised downward or withdrawn entirely at the discretion of the issuing rating agency if in its judgment circumstances so warrant. Any such downward revision or withdrawal of a rating could have an adverse effect on the market price of the notes.

S-6

USE OF PROCEEDS

We estimate that the net proceeds from this offering will be approximately $    million after deducting underwriting discounts and estimated offering expenses. We intend to use the net proceeds of this offering for general corporate purposes, including capital contributions to our insurance subsidiaries to support organic growth.

S-7

The description is qualified in its entirety by reference to the base indenture, dated as of January 3, 2018, between Athene Holding Ltd. and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (the “Trustee”) ( as amended by the Eighth Supplemental Indenture, dated as of December 31, 2023 between Athene Holding Ltd., a corporation organized under the State of Delaware (as successor to Athene Holding Ltd., a Bermuda exempted company) and the Trustee, the “Base Indenture”), as supplemented by the Ninth Supplemental Indenture (the “Ninth Supplemental Indenture” and, together with the Base Indenture, the “Indenture”) to be entered into between Athene Holding Ltd. and the Trustee, to be dated as of    , 2024. The Indenture has been qualified as an indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the Indenture are those provided in the Base Indenture and the Ninth Supplemental Indenture and those made part of the Indenture by the Trust Indenture Act.

The following description of certain terms of the notes and certain provisions of the Indenture, as supplemented by the Ninth Supplemental Indenture, supplements the description under “Description of Debt Securities” in the accompanying prospectus. To the extent that the following description is not consistent with that contained in the accompanying prospectus under “Description of Debt Securities” you should rely on this description. This description is only a summary of the material terms and does not purport to be complete. We urge you to read the Indenture, as supplemented by the Ninth Supplemental Indenture, in its entirety because it, and not this description, will define your rights as a beneficial holder of the notes.

Unless otherwise stated or the context otherwise requires, references in this “Description of the Senior Notes” to “Athene Holding Ltd.,” “we,” “our,” “us,” or “the Company” refer only to Athene Holding Ltd. and not to any of its subsidiaries.

Certain Terms of the Notes

The notes will initially be limited in aggregate principal amount to $    . There is no limit on the aggregate principal amount of notes that Athene Holding Ltd. may issue. The notes will be issued in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The notes will mature on    , 20  (the “Stated Maturity Date”) and will bear interest at  % per annum. Interest will accrue from    , 2024 or from the most recent interest payment date to which interest has been paid or duly provided for.

Interest on the notes will be payable semi-annually in arrears on    and    of each year, commencing    , 2024 (or, if such day is not a Business Day (as defined below), on the next succeeding Business Day (without any interest or other payment in respect of any such delay), with the same force and effect as if made on the date the payment was originally payable), to the persons in whose names the notes are registered at the close of business on the preceding    or    , as the case may be (whether or not a Business Day), provided that interest payable at the Stated Maturity Date or upon redemption will be paid to the person to whom principal is payable. Interest on the notes will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Trustee will act as paying agent for the notes.

Notwithstanding anything to the contrary in this prospectus supplement, so long as the notes are in book-entry form, Athene Holding Ltd. will make payments of principal, premium, if any, and interest through the Trustee to The Depository Trust Company (“DTC”).

“Business Day” means any day other than a day on which the federal or state banking institutions in the Borough of Manhattan, The City of New York or a place of payment, are authorized or obligated by law, executive order or regulation to close.

S-10

None of the notes will be entitled to any sinking fund.

The notes and the Indenture will be governed by, and construed in accordance with, the laws of the State of New York.

Further Issues

Athene Holding Ltd. may, without the consent of the holders of the notes, issue additional senior notes having the same ranking and the same interest rate, maturity and other terms of the notes offered by this prospectus supplement, except for the price to the public and issue date and, in some cases, the first interest payment date and interest accrual date. Any additional notes having such similar terms will constitute a single series of debt securities under the Indenture, provided that if any such additional notes are not issued in a “qualified reopening” or are not treated as part of the same issue as the notes offered by this prospectus supplement for U.S. federal income tax purposes, such additional notes shall have a separate CUSIP number. No additional notes of the same series as a series of the notes may be issued if an Event of Default under the Indenture has occurred and is continuing with respect to outstanding notes of such series.

Ranking

The notes will rank senior in right of payment to any of Athene Holding Ltd.’s indebtedness that is expressly subordinated in right of payment to the notes (including $575 million in aggregate principal amount of 7.250% Fixed-Rate Reset Junior Subordinated Debentures due 2064); equal in right of payment to Athene Holding Ltd.’s unsecured indebtedness (including $1.0 billion in aggregate principal amount of 4.125% Senior Notes due 2028, $500 million in aggregate principal amount of 6.150% Senior Notes due 2030, $500 million in aggregate principal amount of 3.500% Senior Notes due 2031, $400 million in aggregate principal amount of 6.650% Senior Notes due 2033, $500 million in aggregate principal amount of 3.950% Senior Notes due 2051, $500 million in aggregate principal amount of 3.450% Senior Notes due 2052 and $600 million in aggregate principal amount of 5.875% Senior Notes due 2034) and other liabilities that are not so subordinated; effectively junior in right of payment to any of Athene Holding Ltd.’s secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally subordinated to all indebtedness and other liabilities (including interest sensitive contract liabilities, future policy benefits, market risk benefits and other payables) of Athene Holding Ltd.’s subsidiaries. The notes will not be obligations of, or guaranteed by, AGM or any entity other than AHL. In the event of Athene Holding Ltd.’s bankruptcy, liquidation, reorganization or other winding up, assets that secure debt ranking senior or equal in right of payment to the notes will be available to pay obligations on the notes only after the secured debt has been repaid in full from these assets. There may not be sufficient assets remaining to pay amounts due on any or all of the notes then outstanding. The Indenture governing the notes will not prohibit Athene Holding Ltd. from incurring additional senior debt or secured debt, nor does it prohibit any of its subsidiaries from incurring additional liabilities.

As of December 31, 2023, Athene Holding Ltd. had $4.3 billion of unsecured senior indebtedness and other liabilities, $1.25 billion of availability under its $1.25 billion unsecured revolving credit facility, and $2.6 billion of availability under its $2.6 billion unsecured revolving liquidity facility. As of December 31, 2023, Athene Holding Ltd.’s subsidiaries had $275 billion of indebtedness and other liabilities (including interest sensitive contract liabilities, future policy benefits, market risk benefits and other payables, but excluding intercompany obligations and liabilities of a type not required to be reflected on a balance sheet of such subsidiaries in accordance with GAAP) to which the notes would have been structurally subordinated.

Optional Redemption

Prior to    , 20  (  months prior to their maturity date) (the “Par Call Date”), Athene Holding Ltd. may redeem the notes at its option, in whole or in part, for cash at any time and from time to time, at a

S-11

redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming the notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus    basis points less (b) interest accrued to the date of redemption, and

(2) 100% of the principal amount of the notes to be redeemed,

plus, in either case, accrued and unpaid interest thereon to, but excluding, the redemption date.

On or after the Par Call Date, Athene Holding Ltd. may redeem the notes, in whole or in part, for cash at any time and from time to time, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest thereon to, but excluding, the redemption date.

“Treasury Rate” means, with respect to any redemption date, the yield determined by Athene Holding Ltd. in accordance with the following two paragraphs.

The Treasury Rate shall be determined by Athene Holding Ltd. after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, Athene Holding Ltd. shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.

If on the third Business Day preceding the redemption date H.15 TCM or any successor designation or publication is no longer published, Athene Holding Ltd. shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, Athene Holding Ltd. shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, Athene Holding Ltd. shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal

S-12

amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

Athene Holding Ltd.’s actions and determinations in determining the redemption price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each holder of notes to be redeemed.

In the case of a partial redemption, selection of the notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. A new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note. For so long as the notes are held by DTC (or another depositary), the redemption of the notes shall be done in accordance with the policies and procedures of the depositary.

Unless Athene Holding Ltd. defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.

Restrictive Covenants

Limitation on Liens. So long as any notes are outstanding, neither Athene Holding Ltd. nor any of its subsidiaries will create, assume, incur or guarantee any indebtedness for borrowed money which is secured by a mortgage, pledge, lien, security interest or other encumbrance on any capital stock of:

1. any subsidiary that, as of the end of Athene Holding Ltd.’s most recently completed fiscal year, was a “Significant Subsidiary” as such term is defined in Rule 1-02(w) of Regulation S-X promulgated by the SEC; and

2. any successor to substantially all of the business of any subsidiary in clause 1 of this paragraph which is also a subsidiary of Athene Holding Ltd. (each person or successor referred to in clauses 1 and 2 of this paragraph, a “restricted subsidiary”).

However, this restriction will not apply if the notes then outstanding are secured at least equally and ratably with the otherwise prohibited secured indebtedness so long as it is outstanding.

Limitations on Dispositions of Stock of Certain Subsidiaries. So long as any notes are outstanding and subject to the provisions of the Indenture regarding mergers, consolidations and sales of assets, neither Athene Holding Ltd. nor any of its subsidiaries will sell or otherwise dispose of any shares of capital stock (other than preferred stock having no voting rights of any kind) of any restricted subsidiary except for:

1. a sale or other disposition of any of such stock to a wholly owned subsidiary of Athene Holding Ltd.;

2. a sale or other disposition of all of a subsidiary’s stock for at least fair value (as determined by Athene Holding Ltd.’s board of directors acting in good faith); or

3. a sale or other disposition required to comply with an order of a court or regulatory authority of competent jurisdiction, other than an order issued at the request of Athene Holding Ltd. or the request of any of Athene Holding Ltd.’s subsidiaries.

S-13

Consolidation, Merger, Sale of Assets and Other Transactions. So long as any notes are outstanding, Athene Holding Ltd. may not merge with or into or consolidate with another person or sell, assign, transfer, lease or convey all or substantially all of its properties and assets to, any other person other than a direct or indirect wholly owned subsidiary of Athene Holding Ltd., and no person may merge with or into or consolidate with Athene Holding Ltd. or, except for any direct or indirect wholly owned subsidiary of Athene Holding Ltd., sell, assign, transfer, lease or convey all or substantially all of its properties and assets to Athene Holding Ltd., unless:

1. Athene Holding Ltd. is the surviving corporation or the person formed by or surviving such merger or consolidation or to which such sale, assignment, transfer, lease or conveyance has been made, if other than Athene Holding Ltd., is a corporation organized and validly existing under the laws of Bermuda, the United States, any State thereof or the District of Columbia, and has expressly assumed by supplemental indenture all the obligations of Athene Holding Ltd. under the notes and the Indenture;

2. immediately after giving effect to such transaction, no event of default or event that, after notice or lapse of time or both would become an event of default under the Indenture, has occurred and is continuing; and

3. Athene Holding Ltd. delivers to the Trustee an officer’s certificate and an opinion of counsel, each stating that the supplemental indenture required in connection with the transaction complies with the Indenture.

Other than the covenants described above, the Indenture or the notes do not contain other provisions that afford holders of the notes protection in the event we:

• engage in a change of control transaction;

• subject to the covenant discussed above, issue secured debt or secure existing unsecured debt;

• issue debt securities or otherwise incur additional unsecured indebtedness or other obligations;

• purchase or redeem or make any payments in respect of capital stock or other securities ranking junior in right of payment to the notes;

• sell assets;

• pay dividends;

• enter into transactions with related parties; or

• conduct other similar transactions that may adversely affect the holders of the notes.

See “Risk Factors—The notes are protected by only limited restrictive covenants” for a further discussion of the limited protections provided to holders of the notes.

Defeasance

The discharge, defeasance and covenant defeasance provisions of the Indenture described under the caption “Description of Debt Securities—Discharge, Defeasance and Covenant Defeasance” on page 17 of the accompanying prospectus will apply to the notes.

Notices

Athene Holding Ltd. will mail or transmit (as applicable) notices to the addresses of the holders of the notes that are shown on the register for the notes.

Book-Entry; Delivery and Form

The notes will be represented by one or more fully registered global security certificates, each of which is referred to in this prospectus supplement as a “Global Security.” Each such Global Security will be deposited

S-14

with, or on behalf of, DTC and registered in the name of DTC or a nominee thereof. Unless and until it is exchanged in whole or in part for notes in definitive form, no Global Security may be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any such nominee to a successor of DTC or a nominee of such successor.

Except under limited circumstances, notes represented by a Global Security will not be exchangeable for, and will not otherwise be issuable as, notes in certificated form. Investors may elect to hold interests in the Global Securities through either DTC (in the United States) or through Clearstream or Euroclear, if they are participants in such systems, or indirectly through organizations which are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers’ securities accounts in Clearstream’s and Euroclear’s names on the books of their respective depositaries, which in turn will hold such interests in customers’ securities accounts in the depositaries’ names on the books of DTC.

Beneficial interests in the notes will be represented through book-entry accounts of financial institutions acting on behalf of Beneficial Owners (as defined below) as Direct and Indirect Participants (as defined below) in DTC. So long as DTC, or its nominee, is a registered owner of a Global Security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by such Global Security for all purposes under the Indenture. Except as provided below, the actual owners of the notes represented by a Global

Security (the “Beneficial Owners”) will not be entitled to have the notes represented by such Global Security registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form and will not be considered the owners or holders thereof under the Indenture.

Accordingly, each person owning a beneficial interest in a Global Security must rely on the procedures of DTC and, if such person is not a participant of DTC (a “Participant”), on the procedures of the Participant through which such person owns its interest, to exercise any rights of a holder of the notes. Under existing industry practices, in the event that any action is requested of, or entitled to be given or taken under the Indenture by, holders of the notes, DTC would authorize the Participants holding the relevant beneficial interests to give or take such action, and such Participants would authorize Beneficial Owners owning through such Participants to give or take such action or would otherwise act upon the instructions of Beneficial Owners.

The following is based on information furnished by DTC:

DTC will act as securities depositary for the notes. The notes will be fully registered securities registered in the name of Cede & Co. (DTC’s partnership nominee). One or more Global Securities will initially represent the notes and will be deposited with DTC.

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds securities that its Participants deposit with DTC. DTC also facilitates the settlement among Participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in Participants’ accounts, thereby eliminating the need for physical movement of securities certificates. Direct Participants of DTC (“Direct Participants”) include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to DTC’s system is also available to others such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The rules applicable to DTC and its Participants are on file with the SEC.

S-15

Purchases of the notes under DTC’s system must be made by or through Direct Participants, which will receive a credit for the notes on DTC’s records. The ownership interest of each Beneficial Owner is in turn to be recorded on the records of Direct Participants and Indirect Participants. Beneficial Owners will not receive written confirmation from DTC of their purchase, but Beneficial Owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the Direct Participants or Indirect Participants through which such Beneficial Owner entered into the transaction. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in the notes, except in the limited circumstances that may be provided in the Indenture.

To facilitate subsequent transfers, all notes deposited with DTC are registered in the name of DTC’s partnership nominee, Cede & Co. The deposit of the notes with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the notes. DTC’s records reflect only the identity of the Direct Participants to whose accounts such securities are credited, which may or may not be the Beneficial Owners. The Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. will consent or vote with respect to the notes. Under its usual procedures, DTC mails an Omnibus Proxy to Athene Holding Ltd. as soon as possible after the applicable record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts securities are credited on the applicable record date (identified in a listing attached to the Omnibus Proxy).

Payments on the notes will be made in immediately available funds to DTC. DTC’s practice is to credit Direct Participants’ accounts on the applicable payment date in accordance with their respective holdings shown on DTC’s records unless DTC has reason to believe that it will not receive payment on such date. Payments by Participants to Beneficial Owners will be governed by standing instructions and customary practices, and will be the responsibility of such Participant and not of DTC, the Trustee or Athene Holding Ltd., subject to any statutory or regulatory requirements as may be in effect from time to time. Any payment due to DTC on behalf of Beneficial Owners is Athene Holding Ltd.’s responsibility or the responsibility of the applicable agent, disbursement of such payments to Direct Participants shall be the responsibility of DTC, and disbursement of such payments to the Beneficial Owners shall be the responsibility of Direct Participants and Indirect Participants.

If: (i) DTC notifies Athene Holding Ltd. that it is unwilling or unable to continue to act as securities depositary for the notes and no successor securities depositary has been appointed pursuant to the Indenture within 90 days after such notice; (ii) DTC ceases to be a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act when the securities depositary is required to be so registered and so notifies Athene Holding Ltd., and no successor securities depositary has been appointed pursuant to the Indenture within 90 days after such notice; (iii) any Event of Default or default under the Indenture has occurred and is continuing; or (iv) the Company in its sole discretion and subject to DTC’s procedures determines that the notes shall be exchangeable for notes in definitive registered form; then (x) security certificates may be prepared by Athene Holding Ltd. with respect to the notes in definitive registered form without coupons and delivered to the Trustee and (y) upon surrender of the Global Securities representing the notes by DTC (or any successor securities depositary), accompanied by registration instructions, Athene Holding Ltd. will cause such security certificates in definitive registered form representing the notes to be delivered to Beneficial Owners in accordance with the instructions of DTC (or such successor securities depositary).

S-16

Clearstream has advised that it is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participants (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry transfers between their accounts. Clearstream provides Clearstream Participants with, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic securities markets in several countries through established depository and custodial relationships. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Sector, also known as the Commission de Surveillance du Secteur Financier. Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations. Clearstream Participants in the U.S. are limited to securities brokers and dealers and banks and may include the underwriters. Indirect access to Clearstream is also available to other institutions such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with Clearstream Participants. Distributions with respect to interests in global securities held through Clearstream will be credited to cash accounts of its customers in accordance with its rules and procedures, to the extent received by the U.S. depositary for Clearstream.

Euroclear has advised that it was created in 1968 to hold securities for its participants and to clear and settle transactions between Euroclear participants (“Euroclear Participants”) through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing, and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank SA/NV under contract with Euroclear plc, a U.K. corporation. Euroclear Participants include banks, including central banks, securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

Global Clearance and Settlement Procedures

Secondary market trading between the DTC Participants will occur in the ordinary way in accordance with the DTC rules and will be settled in immediately available funds. Secondary market trading between Clearstream Participants and/or Euroclear Participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear and will be settled using the procedures applicable to conventional Eurobonds in immediately available funds.

Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream Participants or Euroclear Participants, on the other, will be effected in DTC in accordance with the DTC rules on behalf of the relevant European international clearing system by DTC in its capacity as U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to DTC to take action to effect final settlement on its behalf by delivering interests in the notes to or receiving interests in the notes from DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream Participants and Euroclear Participants may not deliver instructions directly to DTC.

Because of time-zone differences, credits of interests in the notes received in Clearstream or Euroclear as a result of a transaction with a DTC Participant will be made during subsequent securities settlement processing and will be credited the Business Day following the DTC settlement date. Such credits or any transactions involving interests in such notes settled during such processing will be reported to the relevant Euroclear or Clearstream Participants on such Business Day. Cash received in Clearstream or Euroclear as a result of sales of

S-17

interests in the notes by or through a Clearstream Participant or a Euroclear Participant to a DTC Participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the Business Day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.

The information in this section concerning DTC and its book-entry system, Euroclear and Clearstream has been obtained from sources that we believe to be reliable.

Concerning the Trustee

U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, will initially be the trustee under the Indenture and also the paying agent and the transfer agent and registrar for the notes. We have entered, and from time to time may continue to enter, into banking or other relationships with U.S. Bank Trust Company, National Association or its affiliates. See “Description of Debt Securities—Relationship with the Trustees” beginning on page 19 in the accompanying prospectus.

S-18

TAX CONSIDERATIONS

The following is a discussion of material U.S. federal income tax and U.K. interest withholding tax considerations that may be relevant in connection with this offering.

U.S. Federal Income Tax Considerations

The following discussion summarizes certain U.S. federal income tax considerations relating to the ownership and disposition of the notes. This summary does not provide a complete analysis of all potential U.S. federal income tax considerations. The information provided below is based on existing U.S. federal income tax authorities, all of which are subject to change or differing interpretations, possibly with retroactive effect. There can be no assurances that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences described herein, and we have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the U.S. federal income tax consequences of holding or disposing of the notes. This summary applies only to beneficial owners of the notes that purchase their notes in this offering for an amount equal to the issue price of the notes, which is the first price at which a substantial amount of the notes is sold for money to the public (not including sales to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers), and that hold the notes as “capital assets” for U.S. federal income tax purposes (generally, for investment). This discussion does not purport to deal with all aspects of U.S. federal income taxation that may be relevant to a particular beneficial owner in light of the beneficial owner’s circumstances (for example, persons subject to the alternative minimum tax provisions of the Internal Revenue Code of 1986, as amended (the “Code”), or a holder whose “functional currency” is not the U.S. dollar). Also, it is not intended to be wholly applicable to all categories of investors, some of which may be subject to special rules (such as partnerships and other pass-through entities and investors in such entities, dealers in securities or currencies, traders in securities that elect to use a mark-to-market method of tax accounting, banks, thrifts, regulated investment companies, real estate investment trusts, insurance companies, tax-exempt entities, tax-deferred or other retirement accounts, certain former citizens or residents of the United States, governments and their controlled entities, accrual basis taxpayers subject to special tax accounting rules as a result of their use of certain applicable financial statements, persons holding the notes as part of a hedging, conversion or integrated transaction or a straddle, or persons deemed to sell the notes under the constructive sale provisions of the Code). Finally, the summary does not address the potential application of the Medicare contribution tax on net investment income imposed by Section 1411 of the Code, the effects of the U.S. federal estate and gift tax laws or any applicable non-U.S., state or local laws.

INVESTORS CONSIDERING THE PURCHASE OF NOTES SHOULD CONSULT THEIR OWN TAX ADVISORS REGARDING THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AND THE CONSEQUENCES OF U.S. FEDERAL ESTATE AND GIFT TAX LAWS, NON-U.S., STATE AND LOCAL LAWS, AND TAX TREATIES.

As used herein, the term “U.S. holder” means a beneficial owner of a note that, for U.S. federal income tax purposes, is (1) an individual citizen or resident of the United States, (2) a corporation, or an entity treated as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States, any state of the United States, or the District of Columbia, (3) an estate the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust if (x) it is subject to the primary supervision of a U.S. court and one or more U.S. persons has the authority to control all substantial decisions of the trust or (y) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

If a partnership (including an entity or arrangement, domestic or foreign, treated as a partnership for U.S. federal income tax purposes) is a beneficial owner of a note, the tax treatment of a partner in the partnership will depend upon the status of the partner and the activities of the partnership. A beneficial owner of a note that is a partnership, and partners in such partnership, should consult their own tax advisors about the U.S. federal income tax consequences of holding or disposing of the note.

Tax Consequences Applicable to the Notes

U.S. Holders

Taxation of Interest on the Notes

U.S. holders will be required to recognize as ordinary income any stated interest paid or accrued on the notes, in accordance with their regular method of tax accounting. It is expected, and this discussion assumes, that the notes will not be issued with more than a specified de minimis amount of original issue discount, such that the notes will be treated as issued without original issue discount.

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of the Notes

A U.S. holder generally will recognize capital gain or loss if the holder disposes of a note in a sale, exchange, retirement, redemption or other taxable disposition. The U.S. holder’s gain or loss will equal the difference between the proceeds received by the holder (other than amounts attributable to accrued but unpaid interest) and the holder’s tax basis in the note. The proceeds received by the U.S. holder will include the amount of any cash and the fair market value of any other property received for the note. The U.S. holder’s tax basis in the note generally will equal the amount the holder paid for the note. The portion of any proceeds that is attributable to accrued interest will not be taken into account in computing the U.S. holder’s capital gain or loss. Instead, that portion will be recognized as ordinary interest income to the extent that the U.S. holder has not previously included the accrued interest in income. The gain or loss recognized by the U.S. holder on the disposition of the note will be long-term capital gain or loss if the holder held the note for more than one year, or short-term capital gain or loss if the holder held the note for one year or less, at the time of the disposition. Long-term capital gains of non-corporate taxpayers currently are taxed at reduced rates. Short-term capital gains are taxed at ordinary income rates. The deductibility of capital losses is subject to limitations.

Non-U.S. Holders

For purposes of this discussion, you are a “Non-U.S. holder” if you are a beneficial owner of our notes, you are not a U.S. holder and you are not treated as a partnership for U.S. federal income tax purposes.

Taxation of Interest on the Notes

Interest on the notes will be U.S. source interest for U.S. federal withholding tax purposes. Generally, interest paid on a note to a Non-U.S. holder will qualify for the “portfolio interest” exemption and, subject to the discussions below regarding backup withholding and FATCA (as defined below), will not be subject to U.S. federal income tax or withholding tax; provided that such interest income is not effectively connected with a U.S. trade or business of the Non-U.S. holder and that the Non-U.S. holder:

• does not directly or indirectly, actually or by attribution, own 10% or more of the total combined voting power of all classes of our stock entitled to vote;

• is not a controlled foreign corporation for U.S. federal income tax purposes that is related to us directly or indirectly, actually or by attribution, through sufficient stock ownership under the Code;

• is not a bank receiving interest on an extension of credit made pursuant to a loan agreement entered into in the ordinary course of its business; and

• either (a) provides the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or a suitable substitute form), as applicable, signed under penalties of perjury, that includes the Non-U.S. holder’s name and address, and certifies as to non-U.S. status in compliance with applicable law and regulations; or (b) holds the note through a securities clearing organization, bank or other financial institution that holds customers’ securities in the ordinary course of its trade or business and provides a statement to the applicable withholding agent, signed under penalties of perjury, in which it certifies that such a Form W-8 (or a suitable substitute form) has been received by

S-20

it from the Non-U.S. holder or an intermediate financial institution and furnishes the applicable withholding agent with a copy thereof. The Treasury regulations provide special certification rules for notes held by a foreign partnership and other intermediaries.

If such Non-U.S. holder cannot satisfy the requirements for the “portfolio interest” exemption described above, payments of interest made to the Non-U.S. holder will be subject to 30% U.S. federal tax withholding unless (i) the interest is effectively connected with a U.S. trade or business of such Non-U.S. holder (and, if required by an applicable tax treaty, is attributable to a permanent establishment maintained by the Non-U.S. holder within the U.S.) and such Non-U.S. holder satisfies the applicable certification requirements (as discussed below) or (ii) such holder provides the applicable withholding agent with a properly executed IRS Form W-8BEN or W-8BEN-E (or a suitable substitute form), as applicable, claiming an exemption from (or reduction of) withholding under the benefit of a tax treaty.

If interest on a note is, or is deemed to be, effectively connected with a U.S. trade or business of a Non-U.S. holder (and, if required by an applicable tax treaty, is attributable to a permanent establishment maintained by the Non-U.S. holder within the U.S.), the Non-U.S. holder generally will not be subject to withholding if the Non-U.S. holder complies with applicable IRS certification requirements (i.e., by delivering a properly executed IRS Form W-8ECI or a suitable substitute form) and generally will be subject to U.S. federal income tax on such interest on a net income basis at regular U.S. rates in the same manner as if the holder were a U.S. holder. In the case of a Non-U.S. holder that is treated as a corporation for U.S. federal income tax purposes, such effectively connected income also would generally be subject to an additional branch profits tax, which generally is imposed on a foreign corporation on the deemed repatriation from the U.S. of effectively connected earnings and profits at a 30% rate (or such lower rate as may be prescribed by an applicable tax treaty).

Sale, Exchange, Retirement, Redemption or Other Taxable Disposition of the Notes

Subject to the discussions below regarding backup withholding and FATCA, any gain recognized by a Non-U.S. holder on the sale, exchange, retirement, redemption, or other taxable disposition of a note (other than amounts properly attributable to accrued but unpaid interest, which are treated as described under “—Taxation of Interest on the Notes” above) will not be subject to U.S. federal income tax or withholding, unless:

• the gain is effectively connected with the conduct of a U.S. trade or business of the Non-U.S. holder (and, if required by an applicable tax treaty, the gain is attributable to a permanent establishment maintained in the U.S. by the Non-U.S. holder), in which case such gain will generally be subject to U.S. federal income tax (and branch profits tax, if the Non-U.S. holder is a corporation) in the same manner as effectively connected interest as described above; or

• the Non-U.S. holder is an individual who is present in the U.S. for 183 days or more during the taxable year of that disposition (but is not considered a resident of the United States under specific rules), and certain other conditions are met, in which case the Non-U.S. holder will generally be subject to U.S. federal income tax at a 30% rate (or such lower rate as may be prescribed by an applicable tax treaty) on any gain recognized, which may be offset by certain U.S. source losses.

Non-U.S. holders should consult their tax advisors regarding the tax consequences of the disposition of the notes.

Backup Withholding and Information Reporting

The Code and U.S. Treasury regulations generally require those who make specified payments to report the payments to the IRS. Among the specified payments are interest and proceeds paid by brokers to their customers. This reporting regime is reinforced by “backup withholding” rules, which require the payor to withhold from payments to certain recipients subject to information reporting if any such recipient has failed to provide a

S-21

taxpayer identification number to the payor, furnished an incorrect taxpayer identification number, or failed to report interest or dividends on tax returns.

Payments of interest to holders of the notes and payments made to holders by a broker upon a sale of the notes generally will be subject to information reporting and backup withholding, unless the holder (1) is an exempt payee, or (2) in the case of backup withholding, provides the payor with a correct taxpayer identification number and complies with applicable certification requirements. Non-U.S. holders and all corporations are generally exempt payees, but may required to certify their exempt status under applicable rules. In any event, information returns generally will be filed with the IRS in connection with payments of interest on the notes to Non-U.S. holders and may be made available to the tax authorities in Non-U.S. holders’ jurisdictions under the provisions of a treaty or intergovernmental agreement.

Backup withholding is not an additional tax. Any amounts withheld from a payment to a U.S. holder of notes under the backup withholding rules will be allowed as a refund or can be credited against any U.S. federal income tax liability of the holder, provided the required information is furnished timely to the IRS.

Foreign Account Tax Compliance Act (“FATCA”)

FATCA imposes a 30% withholding tax on certain payments of U.S. source income, including payments of interest on the notes, and gross proceeds to (1) a “foreign financial institution” (as defined in Section 1471(d)(4) of the Code and the U.S. Treasury regulations promulgated thereunder), unless the foreign financial institution enters into an agreement with the IRS to, among other things, collect and disclose to the IRS certain information regarding its U.S. accounts or meets an applicable exception, and (2) a “non-financial foreign entity” (as defined in Section 1472(d) of the Code and the U.S. Treasury regulations promulgated thereunder), unless the entity provides the payor with certain information regarding certain direct and indirect U.S. owners of the entity, certifies that it has no such U.S. owners or meets an applicable exception. A foreign financial institution located in a jurisdiction that has entered into an “intergovernmental agreement” with the United States in respect of FATCA may be required to collect and disclose the relevant tax information to the tax authority in its home jurisdiction and may be subject to rules that differ in certain other respects. Under proposed U.S. Treasury regulations that may be relied upon pending finalization, FATCA withholding tax on gross proceeds is not currently expected to apply.

All of the payments of interest on the notes will be treated as U.S.-source income and therefore subject to withholding and information reporting under FATCA unless a holder (and any intermediaries through which the holder holds its notes) establishes an exemption from such withholding and information reporting.

United Kingdom Interest Withholding Tax Considerations

U.K. Interest Withholding

Payments of interest may be subject to statutory withholding (by the payer) on account of U.K. income tax, where the underlying interest is treated as ‘yearly interest arising in the U.K.’. The determination of whether interest ‘arises in the U.K.’ (for U.K. withholding purposes) can be complex and relies on the application of a number of different factors to the specific facts and circumstances. It is not, however, generally anticipated that payments of interest made by the Company on the notes should be treated as ‘arising in the U.K.’ and hence the Company does not expect to apply withholding on account of U.K. income tax to such payments.

UNDERWRITING

We have entered into an underwriting agreement with Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC and RBC Capital Markets, LLC, as representatives of the underwriters, with respect to the notes. Subject to the terms and conditions set forth in the underwriting agreement, we have agreed to sell to the underwriters, and the underwriters have agreed to purchase from us, the principal amount of the notes that appears opposite their respective names in the table below.

Underwriters	Principal Amount of Notes
Deutsche Bank Securities Inc.	$
Goldman Sachs & Co. LLC
Morgan Stanley & Co. LLC
RBC Capital Markets, LLC
Total	$

Subject to the terms and conditions set forth in the underwriting agreement, the underwriters have agreed to purchase all of the notes offered if any of them are purchased. The underwriting agreement provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may be increased or the offering may be terminated.

The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters’ right to reject any order in whole or in part.

In the underwriting agreement, we have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

The underwriters are offering the notes, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the notes, and other conditions contained in the underwriting agreement, such as the receipt by the underwriters of officer’s certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering:

	Underwriting Discounts paid by us
Per Note		%
Total	$

We estimate that our share of the total expenses of the offering, excluding underwriting discounts, will be approximately $    million.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any national securities exchange or for inclusion of the notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the notes after completion of the offering. However, they are under no obligation to do so and may discontinue any

S-23

market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the notes. If an active trading market for the notes does not develop, the market price and liquidity of the notes may be adversely affected. If the notes are traded, they may trade at a discount from their initial offering price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

We have agreed that, for a period from the date of this prospectus supplement through and including the closing of this offering, we will not, without the prior written consent of Deutsche Bank Securities Inc., Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC and RBC Capital Markets, LLC, offer for sale, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise transfer or dispose of, or enter into any swap or other agreement that transfers any of the economic consequences of ownership of, or file a registration statement with the SEC relating to, any securities substantially similar to the notes (provided, that nothing contained in any agreements relating to the notes shall prohibit or in any way restrict, or be deemed to prohibit or in any way restrict, the issuance of notes by a special purpose trust formed solely to hold funding agreements and to issue funding agreement backed notes).

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include overallotment, stabilizing transactions and syndicate covering transactions. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of such notes. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those transactions. If the underwriters engage in stabilizing or syndicate covering transactions, they may discontinue them at any time.

The underwriters may also impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the underwriters have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

Neither we nor the underwriters make any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the notes. In addition, neither we nor the underwriters make any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

The underwriters are full service financial institutions engaged in various activities, which may include securities trading, commercial and investment banking, financial advisory, investment management, principal investment, insurance and reinsurance related brokering, hedging, financing and brokerage activities. The underwriters and their respective affiliates have in the past performed, and may in the future perform, various commercial banking, investment banking and advisory services for Athene and Apollo from time to time for which they have received customary fees and reimbursement of expenses and may, from time to time, engage in transactions with and perform services for Athene and Apollo in the ordinary course of their business for which they may receive customary fees and reimbursement of expenses.

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 (which may include bank loans and/or credit default swaps) for their own accounts and for the accounts of their customers and may at any time hold long and short positions in such securities and instruments. Such investments and securities activities may involve securities and/or instruments of Athene and Apollo or their affiliates. The underwriters and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.

S-24

In addition, because the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, and certain other of those underwriters or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, such underwriters and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby.

Certain affiliates of Athene or Apollo, which may include executive officers or directors, indicated an interest in purchasing notes in this offering at the public offering price, or from time to time in the open market. The underwriters will receive the same underwriting discount and commissions on notes purchased by such persons in this offering, if any, as they will on any other notes sold to the public in this offering.

Settlement

We expect that delivery of the notes will be made against payment therefor on or about    , 2024, which will be the    business day following the date of pricing of the notes (such settlement cycle being herein referred to as “T+    ”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes prior to the delivery of the notes hereunder will be required, by virtue of the fact that the notes initially will settle T+    , to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery should consult their own advisor.

Selling Restrictions

European Economic Area

None of this prospectus supplement, the accompanying prospectus or any related free writing prospectus is a prospectus for the purposes of the Prospectus Regulation (as defined below). This prospectus supplement, the accompanying prospectus and any related free writing prospectus have been prepared on the basis that any offer of notes in any member state of the European Economic Area (“EEA”) will only be made to a legal entity which is a qualified investor under the Prospectus Regulation (“Qualified Investors”). Accordingly any person making or intending to make an offer in that member state of the EEA of notes which are the subject of the offering contemplated in this prospectus supplement, the accompanying prospectus and any related free writing prospectus may only do so with respect to Qualified Investors. Neither the issuer nor the underwriters have authorized, nor do they authorize, the making of any offer of notes other than to Qualified Investors. The expression “Prospectus Regulation” means Regulation (EU) 2017/1129.

PROHIBITION OF SALES TO EEA RETAIL INVESTORS—The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the EEA. For these purposes, (a) a retail investor means a person who is one (or more) of: (i) a retail client as defined in point (11) of Article 4(1) of Directive 2014/65/EU, as amended (“MiFID II”); or (ii) a customer within the meaning of Directive (EU) 2016/97 (the “Insurance Distribution Directive”), where that customer would not qualify as a professional client as defined in point (10) of Article 4(1) of MiFID II; or (iii) not a qualified investor as defined in the Prospectus Regulation and (b) the expression “offer” includes the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe for the notes. Consequently no key information document required by Regulation (EU) No 1286/2014, as amended (the “PRIIPs Regulation”), for offering or selling the notes or otherwise making them available to retail investors in the EEA has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the EEA may be unlawful under the PRIIPs Regulation.

This prospectus supplement, the accompanying prospectus, any related free writing prospectus and any other document or materials relating to the issue of the notes offered hereby is directed only at relevant persons and must not be acted on or relied on by persons who are not relevant persons. In the United Kingdom, the notes offered hereby are only available to, and any investment or investment activity to which this prospectus supplement, the accompanying prospectus and any related free writing prospectus relates will be engaged in only with, relevant persons. Any person in the United Kingdom that is not a relevant person should not act or rely on this prospectus supplement, the accompanying prospectus, any related free writing prospectus or any related document or any of their contents.

Consequently no key information document required by Regulation (EU) No 1286/2014 as it forms part of domestic law of the United Kingdom by virtue of the EUWA (the “U.K. PRIIPs Regulation”) for offering or selling the notes or otherwise making them available to retail investors in the United Kingdom has been prepared and therefore offering or selling the notes or otherwise making them available to any retail investor in the United Kingdom may be unlawful under the U.K. PRIIPs Regulation.

This prospectus is part of a registration statement that we filed with the U.S. Securities and Exchange Commission (the “SEC”) utilizing a “shelf” registration process. Under this shelf process, we and the selling securityholders named in this prospectus and any accompanying prospectus supplement may, from time to time, sell any combination of debt securities, Preferred Stock (as defined below), depositary shares, warrants and units, as described in this prospectus, in one or more offerings. This prospectus provides you with a general description of the securities that we may offer. Each time that securities are sold, a prospectus supplement that will contain specific information about the terms of that offering will be provided. Any accompanying prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any accompanying prospectus supplement together with additional information described under the heading “Where You Can Find More Information; Incorporation by Reference.”

In reviewing the agreements included as exhibits to any of the documents incorporated by reference into this prospectus and any accompanying prospectus supplement, please remember that they are included to provide you with information regarding their terms and are not intended to provide any other factual or disclosure information about us or the other parties to the agreements. The agreements contain representations and warranties by each of the parties to the applicable agreement. These representations and warranties have been made solely for the benefit of the other parties to the applicable agreement and:

• should not in all instances be treated as categorical statements of fact, but rather as a way of allocating the risk to one of the parties if those statements prove to be inaccurate;

• have been qualified by disclosures that were made to the other party in connection with the negotiation of the applicable agreement, which disclosures are not necessarily reflected in the agreement;

• may apply standards of materiality in a way that is different from what may be viewed as material to investors; and

Accordingly, these representations and warranties may not describe the actual state of affairs as of the date they were made or at any other time.

RISK FACTORS

Investing in our securities involves risks. We urge you to carefully consider the risk factors described in our filings with the SEC that are incorporated by reference in this prospectus and in any accompanying prospectus supplement, pricing supplement or free writing prospectus used in connection with an offering of our securities, as well as the information relating to us identified herein in “Special Note Regarding Forward-Looking Statements” before making an investment decision.

Risk Factor Summary

Our business faces significant risks. The factors that make an investment in our business speculative or risky include:

• Our business, financial condition, results of operations, liquidity and cash flows depend on the accuracy of our management’s assumptions and estimates, and we could experience significant gains or losses if these assumptions and estimates differ significantly from actual results.

• We are subject to risks associated with public health crises, such as pandemics and epidemics, including the COVID-19 pandemic which has caused severe disruptions in the US and global economy and could continue to impact our business, financial condition and results of operations.

• Interruption or other operational failures in telecommunications, information technology and other operational systems or a failure to maintain the security, integrity, confidentiality or privacy of sensitive data residing on those systems, including as a result of human error, could have a material adverse effect on our business.

• A financial strength rating downgrade, potential downgrade or any other negative action by a rating agency could make our product offerings less attractive, inhibit our ability to acquire future business through acquisitions or reinsurance and increase our cost of capital, which could have a material adverse effect on our business.

• We rely significantly on third parties for various services, and we may be held responsible for obligations that arise from the acts or omissions of third parties under their respective agreements with us.

• Changes to the method of determining the London Inter-bank Offered Rate (“LIBOR”) or the selection of a replacement for LIBOR may affect the value of investments held by or due to us and could affect our results of operations and financial results.

• We are subject to significant operating and financial restrictions imposed by our credit agreements, liquidity facility, and certain letters of credit, and we are also subject to certain operating restrictions imposed by the indenture to which we are a party.

• We operate in a highly competitive industry that includes a number of competitors, which could limit our ability to achieve our growth strategies and could materially and adversely affect our business, financial condition, results of operations, cash flows and prospects.

• If we are unable to attract and retain independent marketing organizations, agents, banks and broker-dealers, sales of our products may be adversely affected.

• Our growth strategy includes acquisitions and block reinsurance transactions, and our ability to consummate these transactions on economically advantageous terms acceptable to us in the future is unknown.

• As a financial services company, we are exposed to liquidity risk, which is the risk that we are unable to meet near-term obligations as they come due.

2

• The amount of statutory capital that our insurance and reinsurance subsidiaries have, or that they are required to hold, can vary significantly from time to time and is sensitive to a number of factors outside of our control.

• Repurchase agreement programs subject us to potential liquidity and other risks.

• Our investments are subject to market and credit risks that could diminish their value and these risks could be greater during periods of extreme volatility or disruption in the financial and credit markets, which could adversely impact our business, financial condition, results of operations, liquidity and cash flows.

• Interest rate fluctuations could adversely affect our business, financial condition, results of operations, liquidity and cash flows.

• We are subject to the credit risk of our counterparties, including ceding companies, reinsurers, plan sponsors and derivative counterparties.

• Our investment portfolio may be subject to concentration risk, particularly with respect to single issuers, including Athora Holding Ltd., among others; industries, including financial services; and asset classes, including real estate.

• Many of our invested assets are relatively illiquid and we may fail to realize profits from these assets for a considerable period of time, or lose some or all of the principal amount we invest in these assets if we are required to sell our invested assets at a loss at inopportune times.

• Our investments linked to real estate are subject to credit risk, market risk, servicing risk, loss from catastrophic events and other risks, which could diminish the value that we obtain from such investments.

• Our investment portfolio may include investments in securities of issuers based outside the US, including emerging markets, which may be riskier than securities of US issuers.

• While we seek to hedge foreign currency risks, foreign currency fluctuations may reduce our net income and our capital levels, adversely affecting our financial condition.

• Climate change and regulatory and other efforts to reduce climate change, as well as environmental, social and governance requirements could adversely affect our business.

• Financial markets have been subject to inflationary pressures, and continued rising inflation may adversely impact our business and results of operations.

• There are potential conflicts of interests between Apollo Global Management, Inc. (“AGM”), our corporate parent, or any of its subsidiaries (collectively, AGM together with its subsidiaries, “Apollo”), and the holders of our Preferred Stock.

• We rely on our investment management agreements with Apollo for the management of our investment portfolio. Apollo may terminate these arrangements at any time, and there are limitations on our ability to terminate investment management agreements covering assets backing reserves and surplus in ACRA (as defined below), which may adversely affect our investment results.

• Interruption or other operational failures in telecommunications, information technology and other operational systems at Apollo or a failure to maintain the security, integrity, confidentiality or privacy of sensitive data residing on Apollo’s systems, including as a result of human error, could have a material adverse effect on our business.

• The historical investment portfolio performance of Apollo should not be considered as indicative of the future results of our investment portfolio, or our future results or our ability to declare and pay dividends on our Preferred Stock.

• The returns that we expect to achieve on our investment portfolio may not be realized.

3

• Our industry is highly regulated and we are subject to significant legal restrictions and these restrictions may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects.

• Our failure to obtain or maintain licenses and/or other regulatory approvals as required for the operations of our insurance subsidiaries may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects.

• Changes in the laws and regulations governing the insurance industry or otherwise applicable to our business, may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects.

• Our structure involves complex provisions of tax law for which no clear precedent or authority may be available. Our structure is also subject to ongoing future potential legislative, judicial or administrative change and differing interpretations, possibly on a retroactive basis.

• Changes in non-US tax law could adversely affect our ability to raise funds from certain investors.

• The Base Erosion and Anti-Abuse Tax (BEAT) may significantly increase our tax liability.

• Changes in US tax law might adversely affect demand for our products.

• AHL is a holding company with limited operations of its own. As a consequence, AHL’s ability to pay dividends on its securities and to make timely payments on its debt obligations will depend on the ability of its subsidiaries to make distributions or other payments to it, which may be restricted by law.

• We may be the target or subject of, and may be required to defend against or respond to, litigation, regulatory investigations or enforcement actions.

• adverse changes in U.S. or non-U.S. tax law;

OUR COMPANY

We are a leading financial services company that specializes in issuing, reinsuring and acquiring retirement savings products designed for the increasing number of individuals and institutions seeking to fund retirement needs. We generate attractive financial results for our policyholders and stockholders by combining our two core competencies of (1) sourcing long-term, persistent liabilities and (2) using the global scale and reach of Apollo’s asset management business to actively source or originate assets with our preferred risk and return characteristics. Our investment philosophy is to invest a portion of our assets in securities that earn an incremental yield by taking measured liquidity and complexity risk and capitalize on our long-dated funding profile to prudently achieve higher net investment earned rates, rather than assuming incremental credit risk. Our differentiated investment strategy benefits from our relationship with Apollo, which provides a full suite of services for our investment portfolio, including direct investment management, asset allocation, mergers and acquisition asset diligence and certain operational support services, including investment compliance, tax, legal and risk management support. Our relationship with Apollo provides us with access to Apollo’s investment professionals around the world as well as Apollo’s global asset management infrastructure across a broad array of asset classes. We are led by a highly skilled management team with extensive industry experience. Our headquarters are located in West Des Moines, Iowa. Effective January 1, 2022, as a result of the closing of the merger involving us and Apollo, AGM (NYSE: APO) became the beneficial owner of 100% of our common stock and controls all of the voting power to elect members to our board of directors.

The issuer, AHL, is a holding company for its insurance subsidiaries and does not have any significant operations of its own. The principal sources of cash to meet AHL’s obligations are dividends, returns of capital, loans or advances or other intercompany transfers of funds from its subsidiaries. AHL’s insurance subsidiaries are subject to regulatory restrictions on the payment of dividends imposed by the regulators of their respective domiciles. The dividend limitation for Bermuda insurance and reinsurance subsidiaries is based on the statutory capital and surplus as of the immediately preceding calendar year. The dividend limitation for U.S. insurance subsidiaries is based on the surplus to policyholders as of the immediately preceding calendar year and statutory net gain from operations of the immediately preceding calendar year.

AHL is a corporation organized under the laws of the State of Delaware. Our principal executive offices are located at 7700 Mills Civic Pkwy, West Des Moines, Iowa 50266, and our telephone number is 1-888-266-8489. Our website address is www.athene.com. Information contained on our website or connected thereto does not constitute a part of, and is not incorporated by reference into, this prospectus supplement or the accompanying prospectus.

10

USE OF PROCEEDS

We may use the proceeds of securities sold or re-sold by us under this registration statement for, among other things, general corporate purposes. The prospectus supplement for each offering of securities will specify the intended use of the proceeds of that offering.

11

DESCRIPTION OF SECURITIES

This prospectus contains summary descriptions of the debt securities, Preferred Stock, depositary shares, warrants and units that we and selling securityholders may sell from time to time. These summary descriptions are not meant to be complete descriptions of each security. However, this prospectus and any accompanying prospectus supplement together contain the material terms of the securities being offered.

DESCRIPTION OF DEBT SECURITIES

As used in this prospectus, debt securities means the debentures, notes, bonds and other evidences of indebtedness that we may issue from time to time. The debt securities will either be senior debt securities or subordinated debt securities (together, the “debt securities”).

Unless the applicable prospectus supplement states otherwise, (i) senior debt securities will be issued under an Indenture dated as of January 12, 2018 (as supplemented from time to time), between AHL and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (the “Senior Indenture”), and (ii) subordinated debt securities will be issued under an indenture to be entered into between us and a trustee named therein, as trustee (the “Subordinated Indenture” and, together with the Senior Indenture, the “Indentures”).

The Senior Indenture and a form of the Subordinated Indenture are included as exhibits to the registration statement of which this prospectus forms a part. The statements and descriptions in this prospectus or in any prospectus supplement regarding provisions of the Indentures and debt securities are summaries thereof, do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all of the provisions of the Indentures and the debt securities, including the definitions therein of certain terms.

General

The debt securities will be direct secured or unsecured obligations of AHL. The senior debt securities will rank equally with all of AHL’s other senior and unsubordinated debt. The subordinated debt securities will be subordinate and junior in right of payment to all of AHL’s present and future senior indebtedness.

Because AHL is principally a holding company, its right to participate in any distribution of assets of any of its subsidiaries, including ALRe, Athene Annuity & Life Assurance Company (“AADE”) and Athene Annuity and Life Company (“AAIA”), upon such subsidiaries’ liquidation or reorganization or otherwise, is subject to the prior claims of creditors of such subsidiaries, except to the extent AHL may be recognized as a creditor of such subsidiaries. Accordingly, AHL’s obligations under the debt securities will be effectively subordinated to all existing and future indebtedness and liabilities of its subsidiaries, including liabilities under contracts of insurance and annuities written by AHL’s insurance subsidiaries, and holders of debt securities should look only to AHL’s assets for payment thereunder.

The Indentures do not limit the aggregate principal amount of debt securities that AHL may issue and provide that AHL may issue debt securities from time to time in one or more series, in each case with the same or various maturities, at par or at a discount. AHL may issue additional debt securities of a particular series without the consent of the holders of the debt securities of such series outstanding at the time of the issuance. Any such additional debt securities, together with all other outstanding debt securities of that series, will constitute a single series of debt securities under the applicable Indenture. The Indentures do not limit our ability to incur other debt.

Each prospectus supplement will describe the terms relating to the specific series of debt securities being offered. These terms will include some or all of the following:

• the title of debt securities and whether they are subordinated debt securities or senior debt securities;

12

• any limit on the aggregate principal amount of the debt securities;

• the price or prices at which AHL will sell the debt securities;

• the maturity date or dates of the debt securities;

• the rate or rates of interest, if any, which may be fixed or variable, per annum at which the debt securities will bear interest, or the method of determining such rate or rates, if any;

• the date or dates from which any interest will accrue, the dates on which interest will be payable, or the method by which such date or dates will be determined;

• the right, if any, to extend the interest payment periods and the duration of any such deferral period, including the maximum consecutive period during which interest payment periods may be extended;

As used in this prospectus and any prospectus supplement relating to an offering of debt securities, references to the principal of (and premium, if any) and interest, if any, on the debt securities of a series include additional amounts, if any, payable on the debt securities of such series in that context.

Unless otherwise specified in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

Unless otherwise specified in the applicable prospectus supplement, the debt securities will be issued in fully registered form without coupons.

Debt securities may be sold at a substantial discount below their stated principal amount, bearing no interest or interest at a rate which at the time of issuance is below market rates. The applicable prospectus supplement will describe the federal income tax consequences and special considerations applicable to any such debt securities. The debt securities may also be issued as indexed securities or securities denominated in foreign currencies or currency units, as described in more detail in the prospectus supplement relating to any of the particular debt securities. The prospectus supplement relating to specific debt securities will also describe any special considerations and certain additional tax considerations applicable to such debt securities.

Subordination

The prospectus supplement relating to any offering of subordinated debt securities will describe the specific subordination provisions. However, unless otherwise noted in the prospectus supplement, subordinated debt securities will be subordinate and junior in right of payment to all of AHL’s Senior Indebtedness (as described below).

For purposes of subordinated debt securities, “Senior Indebtedness” includes principal of, premium, if any, and interest on, and any other payment due pursuant to any of the following, whether incurred prior to, on or after the date of execution of the Senior Indenture:

• all obligations of AHL for money borrowed;

• all obligations of AHL evidenced by notes, debentures, bonds or other similar instruments, including obligations incurred in connection with the acquisition of property, assets or businesses and including all other debt securities issued by AHL to any trust or a trustee of such trust, or to a partnership or other affiliate that acts as a financing vehicle for AHL, in connection with the issuance of securities by such vehicles;

• all obligations of AHL under leases required or permitted to be capitalized under generally accepted accounting principles;

• all reimbursement obligations with respect to letters of credit, bankers’ acceptances or similar facilities issued for the account of AHL;

14

• all obligations of AHL issued or assumed as the deferred purchase price of property or services, including all obligations under master lease transactions pursuant to which AHL or any of its subsidiaries have agreed to be treated as owner of the subject property for federal income tax purposes (including trade accounts payable or accrued liabilities arising in the ordinary course of business);

• all payment obligations of AHL under interest rate swap or similar agreements or foreign currency hedge, exchange or similar agreements at the time of determination, including any such obligations AHL incurred solely to act as a hedge against increases in interest rates that may occur under the terms of other outstanding variable or floating rate indebtedness of AHL;

• all obligations of the types referred to in the preceding bullet points of another person and all dividends of another person the payment of which, in either case, AHL has assumed or guaranteed or for which AHL is responsible or liable, directly or indirectly, jointly or severally, as obligor, guarantor or otherwise; and

• all amendments, modifications, renewals, extensions, refinancings, replacements and refundings of any of the above types of indebtedness.

Senior Indebtedness does not include indebtedness that is, by its terms, subordinated to, or ranks equal with, the subordinated debt securities.

As of September 30, 2023, AHL had $3.4 billion in aggregate principal amount of Senior Indebtedness outstanding. On December 12, 2023, AHL issued an additional $600 million of unsecured senior indebtedness. The amount of any additional Senior Indebtedness which AHL may issue is subject to limitations imposed by its board of directors.

Senior Indebtedness shall continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.

Unless otherwise noted in the accompanying prospectus supplement, if AHL defaults in the payment of any principal of (or premium, if any) or interest on any Senior Indebtedness when it becomes due and payable, whether at maturity or at a date fixed for prepayment or by declaration or otherwise, then, unless and until such default is cured or waived or ceases to exist, AHL will make no direct or indirect payment (in cash, property, securities, by set-off or otherwise) in respect of the principal of or interest on the subordinated debt securities or in respect of any redemption, retirement, purchase or other requisition of any of the subordinated debt securities.

In the event of the acceleration of the maturity of any subordinated debt securities, the holders of all senior debt securities outstanding at the time of such acceleration will first be entitled to receive cash payment in full of all amounts due on the senior debt securities before the holders of the subordinated debt securities will be entitled to receive any payment of principal (and premium, if any) or interest on the subordinated debt securities.

If any of the following events occurs, AHL will pay in full all Senior Indebtedness before it makes any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, to any holder of subordinated debt securities:

• any dissolution or winding-up or liquidation or reorganization of AHL, whether voluntary or involuntary or in bankruptcy, insolvency or receivership;

• any general assignment by AHL for the benefit of creditors; or

• any other marshaling of AHL’s assets or liabilities.

In such event, any payment or distribution under the subordinated debt securities, whether in cash, securities or other property, which would otherwise (but for the subordination provisions) be payable or deliverable in respect of the subordinated debt securities, will be paid or delivered directly to the holders of Senior Indebtedness in accordance with the priorities then existing among such holders until all Senior Indebtedness has been paid in full. If any payment or distribution under the subordinated debt securities is received by the trustee of any

15

subordinated debt securities in contravention of any of the terms of the Indentures and before all the Senior Indebtedness has been paid in full, such payment or distribution or security will be received in trust for the benefit of, and paid over or delivered and transferred to, the holders of the Senior Indebtedness at the time outstanding in accordance with the priorities then existing among such holders for application to the payment of all Senior Indebtedness remaining unpaid to the extent necessary to pay all such Senior Indebtedness in full.

The Indentures do not limit the issuance of additional Senior Indebtedness.

Events of Default, Notice and Waiver

Unless an accompanying prospectus supplement states otherwise, the following shall constitute “Events of Default” under the Senior Indenture with respect to each series of senior debt securities:

• AHL’s failure to pay any interest on any debt security of such series when due and payable, continued for 30 days;

• AHL’s failure to pay principal (or premium, if any) on any debt security of such series when due, regardless of whether such payment became due because of maturity, redemption, acceleration or otherwise, or is required by any sinking fund established with respect to such series;

• AHL’s failure to observe or perform any other of its covenants or agreements with respect to such series for 90 days after AHL receives notice of such failure;

• certain defaults with respect to AHL’s debt which result in a principal amount in excess of $100,000,000 becoming or being declared due and payable prior to the date on which it would otherwise have become due and payable (other than the debt securities or non-recourse debt); and

• certain events of bankruptcy, insolvency or reorganization of AHL.

Unless an accompanying prospectus supplement states otherwise, the following shall constitute “Events of Default” under the Subordinated Indenture with respect to each series of subordinated debt securities:

• AHL’s failure to pay interest in full or in part, including compounded interest, on any subordinated debt securities for a period of 30 days after such interest was due or on the maturity date;

• AHL’s failure to pay principal of or premium, if any, on any subordinated debt security of such series on the maturity date or upon redemption;

• certain events of bankruptcy, insolvency or reorganization of AHL.

If an Event of Default with respect to any debt securities of any series outstanding under the Indentures shall occur and be continuing, the trustee under such Indenture or the holders of at least 25% in aggregate principal amount of the debt securities of that series outstanding may declare, by notice as provided in such Indenture, the principal amount (or such lesser amount as may be provided for in the debt securities of that series) of all the debt securities of that series outstanding to be due and payable immediately; provided that, in the case of an Event of Default involving certain events in bankruptcy, insolvency or reorganization, acceleration is automatic; and, provided further, that after such acceleration, but before a judgment or decree based on acceleration, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series may, under certain circumstances, rescind and annul such acceleration if all Events of Default, other than the nonpayment of accelerated principal, have been cured or waived. Events of Default with respect to AHL’s subordinated debt securities may be different than those with respect to its senior debt securities. Upon the acceleration of the maturity of original issue discount debt securities, an amount less than the principal amount thereof will become due and payable. Reference is made to the prospectus supplement relating to any original issue discount debt securities for the particular provisions relating to acceleration of maturity thereof.

Any past default under the Indentures with respect to debt securities of any series, and any Event of Default arising therefrom, may be waived by the holders of a majority in principal amount of all debt securities of such series outstanding under such Indenture, except in the case of (i) default in the payment of the principal of (or

16

premium, if any) or interest on any debt securities of such series, or (ii) default in respect of a covenant or provision which may not be amended or modified without the consent of the holder of each outstanding debt security of such series affected.

The trustee is required, within 60 days after the occurrence of a default (which is actually known to the trustee and is continuing), with respect to the debt securities of any series (without regard to any grace period or notice requirements), to give to the holders of the debt securities of such series notice of such default; provided, however, that, except in the case of a default in the payment of the principal of (and premium, if any) or interest, or in the payment of any sinking fund installment, on any debt securities of such series, the trustee shall be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of the debt securities of such series.

The trustee, subject to its duties during default to act with the required standard of care, may require indemnification by the holders of the debt securities of any series with respect to which a default has occurred before proceeding to exercise any right or power under such Indenture at the request of the holders of the debt securities of such series. Subject to such right of indemnification and to certain other limitations, the holders of a majority in aggregate principal amount of the outstanding debt securities of any series under such Indenture may direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee with respect to the debt securities of such series.

No holder of a debt security of any series may institute any action against AHL under the Indentures (except actions for payment of overdue principal of (and premium, if any) or interest on such debt security or for the conversion or exchange of such debt security in accordance with its terms) unless (i) the holder has given to the trustee written notice of an Event of Default and of the continuance thereof with respect to the debt securities of such series specifying an Event of Default, as required under such Indenture, (ii) the holders of at least 25% in aggregate principal amount of the debt securities of that series then outstanding under such Indenture shall have requested the trustee to institute such action and offered to the trustee reasonable indemnity as it may require against the costs, expenses and liabilities to be incurred in compliance with such request, and (iii) the trustee shall not have instituted such action within 60 days of such request.

AHL is required to promptly notify the trustee of the occurrence of any default under the Indentures and is further required to furnish statements to the trustee as to AHL’s compliance with all conditions and covenants under the Indentures and AHL’s knowledge of any default or Event of Default within 120 days of AHL’s fiscal year end.

Discharge, Defeasance and Covenant Defeasance

If indicated in the applicable prospectus supplement, AHL may discharge or defease its obligations (except for certain surviving provisions) under the Indentures as set forth below.

AHL may discharge certain obligations to holders of any series of debt securities issued under an Indenture which have not already been delivered to the applicable trustee for cancellation and which have either become due and payable or are by their terms due and payable within one year (or scheduled for redemption within one year) by irrevocably depositing with the applicable trustee cash or, in the case of debt securities payable only in U.S. dollars, U.S. government obligations (as defined in the Indentures), or a combination thereof, as trust funds in an amount certified to be sufficient to pay when due, whether at maturity, upon redemption or otherwise, the principal of (and premium, if any) and interest on such debt securities.

If indicated in the applicable prospectus supplement, AHL may elect either (i) to defease and be discharged from any and all obligations with respect to the debt securities of or within any series (except as otherwise provided in the Indentures) (“defeasance”) or (ii) to be released from its obligations with respect to certain covenants applicable to the debt securities of or within any series (“covenant defeasance”), upon the deposit with the relevant trustee, in trust for such purpose, of money and/or government obligations which, through the payment of principal and interest in accordance with their terms, will provide money in an amount sufficient, without

17

reinvestment, to pay the principal of (and premium, if any) or interest on such debt securities to maturity or redemption, as the case may be, and any mandatory sinking fund or analogous payments thereon. As a condition to defeasance or covenant defeasance, AHL must deliver to the relevant trustee an opinion of counsel to the effect that the holders and beneficial owners of such debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to U.S. federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred. Such opinion of counsel, in the case of defeasance under clause (i) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the applicable Indenture. In addition, in the case of either defeasance or covenant defeasance, AHL shall have delivered to the relevant trustee (i) an officers’ certificate to the effect that the relevant debt securities exchange(s) have informed it that neither such debt securities nor any other debt securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit, and (ii) an officers’ certificate and an opinion of counsel, each stating that all conditions precedent with respect to such defeasance or covenant defeasance have been complied with.

AHL may exercise its defeasance option with respect to such debt securities notwithstanding its prior exercise of its covenant defeasance option.

Modification and Waiver

Under the Indentures, AHL and the applicable trustee may supplement the Indentures for certain purposes which would not materially adversely affect the interests or rights of the holders of debt securities of a series without the consent of those holders. AHL and the applicable trustee may also modify the relevant Indentures or any supplemental indenture in a manner that affects the interests or rights of the holders of debt securities with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities of each affected series issued under such Indenture. However, the Indentures require the consent of each holder of debt securities that would be affected by any modification which would:

• change the stated maturity of any debt securities of any series, or reduce the principal amount thereof, or reduce the rate or change the time of payment of interest thereon, or reduce any premium payable upon the redemption thereof;

• reduce the amount of principal of an original issue discount debt security or any other debt security payable upon acceleration of the maturity thereof;

• change the currency in which any debt security or any premium or interest is payable;

• impair the right of any holder to enforce any payment on or with respect to any debt security;

• adversely change the right of any holder exercisable upon the repurchase of the debt securities, if the debt securities initially provide for such rights;

• reduce the percentage in principal amount of outstanding debt securities of any series, the consent of whose holders is required for modification or amendment of such Indenture or for waiver of compliance with certain provisions of such Indenture or for waiver of certain defaults;

• reduce the requirements contained in such Indenture for quorum or voting; or

• modify any of the above provisions.

The Indentures permit the holders of at least a majority in aggregate principal amount of the outstanding debt securities of any series issued under the Indenture which is affected by the modification or amendment to waive AHL’s compliance with certain covenants contained in such Indenture.

Payment and Paying Agents

Unless otherwise indicated in the applicable prospectus supplement, payment of interest on a debt security on any interest payment date will be made to the person in whose name a debt security is registered at the close of business on the record date for the interest.

18

Unless otherwise indicated in the applicable prospectus supplement, principal, interest and premium on the debt securities of a particular series will be payable at the office of such paying agent or paying agents as AHL may designate for such purpose from time to time. Notwithstanding the foregoing, at AHL’s option, payment of any interest may be made by check mailed to the address of the person entitled thereto as such address appears in the security register.

Unless otherwise indicated in the applicable prospectus supplement, a paying agent designated by AHL and located in the contiguous United States will act as paying agent for payments with respect to debt securities of each series. All paying agents initially designated by AHL for the debt securities of a particular series will be named in the applicable prospectus supplement. AHL may at any time designate additional paying agents or rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, except that AHL will be required to maintain a paying agent in each place of payment for the debt securities of a particular series.

Subject to applicable abandoned property laws, all moneys paid by AHL to a paying agent for the payment of the principal, interest or premium on any debt security which remain unclaimed at the end of two years after such principal, interest or premium has become due and payable will be repaid to AHL upon request, and the holder of such debt security thereafter may look only to AHL for payment thereof.

Denominations, Registrations and Transfer

Unless an accompanying prospectus supplement states otherwise, debt securities will be represented by one or more global certificates registered in the name of a nominee for The Depository Trust Company (“DTC”). In such case, each holder’s beneficial interest in the global securities will be shown on the records of DTC and transfers of beneficial interests will only be effected through DTC’s records.

A holder of debt securities may only exchange a beneficial interest in a global security for certificated securities registered in the holder’s name if:

• DTC notifies us that it is unwilling or unable to continue serving as the depositary for the relevant global securities or DTC ceases to maintain certain qualifications under the Exchange Act and no successor depositary has been appointed for 90 days; or

• We determine, in our sole discretion and subject to the procedures of DTC, that the global security shall be exchangeable.

If debt securities are issued in certificated form, they will only be issued in the minimum denomination specified in the accompanying prospectus supplement and integral multiples of such denomination. Transfers and exchanges of such debt securities will only be permitted in such minimum denomination. Transfers of debt securities in certificated form may be registered at the applicable trustee’s corporate office or at the offices of any paying agent or trustee appointed by us under the applicable Indenture. Exchanges of debt securities for an equal aggregate principal amount of debt securities in different denominations may also be made at such locations.

Governing Law

The Indentures and debt securities will be governed by, and construed in accordance with, the internal laws of the State of New York, without regard to its principles of conflicts of laws.

Relationship with the Trustees

The trustees under the Indentures are U.S. Bank Trust Company, National Association. We maintain ordinary banking and trust relationships with a number of banks and trust companies, including the trustees under the Indentures.

DESCRIPTION OF PREFERRED STOCK

The following is a description of the terms of our capital stock. This description is a summary only and is qualified by reference to the relevant provisions of the Delaware General Corporation Law (“DGCL”), and our certificate of incorporation (the “certificate of incorporation”), and bylaws (the “bylaws”), which are incorporated by reference in this prospectus.

General

Our certificate of incorporation authorizes 400,000,000 shares, which is divided into two classes as follows:

• 360,000,000 shares of common stock, par value of $0.001 per share (“Common Stock”); and

• 40,000,000 shares of preferred stock, par value of $1.00 per share (“Preferred Stock”), which may be designated from time to time in accordance with our certificate of incorporation.

Common Stock

Effective January 1, 2022, as a result of the closing of the merger involving us and Apollo, Apollo Global Management, Inc. became and remains as of the date of this prospectus the beneficial owner of 100% of our Common Stock and controls all of the voting power to elect members to our board of directors. Our shares of Common Stock are not publicly listed.

Preferred Stock

Our board of directors is authorized, subject to limitations prescribed by Delaware law, to provide, out of the unissued shares of our Preferred Stock, for one or more series of our Preferred Stock, to fix the designation, powers (including voting powers), preferences and relative, participating, optional and other special rights of, and the qualifications, limitations or restrictions thereof, such series of our Preferred Stock and the number of shares of such series, in each case without further vote or action by our stockholders (except as may be required by the terms of our certificate of incorporation and any certificate of designation relating to any series of our Preferred Stock then outstanding). Our board of directors can also increase (but not above the total number of shares of our Preferred Stock then authorized and available for issuance and not committed for other issuance) or decrease (but not below the number of shares of such series then outstanding) the number of shares of any series of our Preferred Stock. Our board of directors may authorize the issuance of our Preferred Stock with voting or conversion rights that could dilute or have a detrimental effect on the proportion of voting power held by, or other relative rights of, the Common Stockholders. The issuance of our Preferred Stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could, among other things, have the effect of delaying, deferring or preventing a change in the control of us and might adversely affect the market price of our Common Stock.

As of January 1, 2024, there were outstanding 34,500 shares of our Series A preferred stock (“Series A Preferred Stock”), 13,800 shares of our Series B preferred stock (“Series B Preferred Stock”), 24,000 shares of our Series C preferred stock (“Series C Preferred Stock”), 23,000 shares of our Series D preferred stock (“Series D Preferred Stock”), and 20,000 shares of our Series E preferred stock (“Series E Preferred Stock”).

Economic Rights

Dividends. The Company shall not make or pay any dividend of cash or other assets with respect to (i) shares of Series A Preferred Stock, (ii) shares of Series B Preferred Stock, (iii) shares of Series C Preferred Stock, (iv) shares of Series D Preferred Stock, (v) shares of Series E Preferred Stock, or (vi) any other series of Preferred Stock, in each case, except for dividends in accordance with the certificate of designation relating to such series of Preferred Stock.

20

Voting Rights

Pursuant to our certificate of incorporation, in connection with any vote of stockholders to approve a merger or amalgamation with respect to the Company (a “Company Merger Vote”), each outstanding share of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, and Series E Preferred Stock shall have the power to vote in connection with any such Company Merger Vote. Solely in connection with any such Company Merger Vote, all outstanding shares of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and Series E Preferred Stock shall collectively represent 0.1% of the total voting power of the Company with the total voting power attributable to each share of the Common Stock being reduced by such percentage on a pro-rated basis. Holders of a series of Preferred Stock issued in the future may not have similar voting rights except as required by applicable law or stock exchange requirements, or as specified in the prospectus supplement and the Certificates of Designation relating to such series.

Certain Provisions of our Charter and Bylaws

Our certificate of incorporation and bylaws and the DGCL contain provisions, which are summarized in the following paragraphs, that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and to discourage certain types of transactions that may involve an actual or threatened acquisition of our Company. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change in control or other unsolicited acquisition proposal, and enhance the ability of our board of directors to maximize stockholder value in connection with any unsolicited offer to acquire us. However, these provisions may have the effect of delaying, deterring or preventing a merger or acquisition of our Company by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest.

Authorized but Unissued Capital Stock

Delaware law does not require stockholder approval for any issuance of shares that are authorized and available for issuance. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital and to facilitate acquisitions and employee benefit plans.

Our board of directors may generally issue shares of one or more series of Preferred Stock on terms designed to discourage, delay or prevent a change of control of us or the removal of our management. Moreover, our authorized but unissued shares of Preferred Stock will be available for future issuances in one or more series without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of authorized and unissued and unreserved Common Stock or Preferred Stock may be to enable our board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive our stockholders of opportunities to sell their shares of Common Stock at prices higher than prevailing market prices.

Election of Directors

Directors are elected at an annual meeting of our stockholders. Subject to the rights of the holders of any series of Preferred Stock with respect to any director elected by holders of Preferred Stock, directors will be elected by a majority of the votes cast by the holders of our outstanding shares of Common Stock present in person or represented by proxy and entitled to vote on the election of directors at such annual meeting. The time, date and place of the annual meeting will be fixed by the board of directors.

21

Removal of Directors

Any director or the whole board of directors (other than a director elected by holders of Preferred Stock) may be removed, with or without cause, at any time, subject to the terms and conditions of any Preferred Stock that is issued and outstanding, by (i) the affirmative vote of the holders of a majority of the outstanding shares of our Common Stock at an annual meeting or at a special meeting of stockholders called for that purpose or (ii) the holders of a majority of the outstanding shares of our Common Stock acting by written consent. In the case of an annual or special meeting of stockholders, the notice of any such meeting of stockholders shall contain a statement of the intention to remove such director with or without cause and be served on such director not less than fourteen (14) days before the meeting, and at such meeting such director shall be entitled to be heard on the motion for his removal; if such director is removed, the stockholders may fill the vacancy at the meeting at which such director is removed, subject to the terms and conditions of any series of Preferred Stock issued and outstanding.

Board Size; Vacancies; Newly Created Directorships

Our certificate of incorporation also provides that, subject to the rights granted to one or more series of our Preferred Stock then outstanding, our board of directors or the holders of Common Stock may, from time to time, set the total number of directors which shall constitute the board of directors, and any newly created directorships or vacancies on our board of directors (other than a director elected by holders of Preferred Stock) may only be filled by the affirmative vote of a majority of the remaining directors, even if less than a quorum, or by a sole remaining director or by the affirmative vote of holders of a majority of our Common Stock outstanding at a stockholder meeting called for the purpose of filling such vacancy or by the holders of a majority of our Common Stock outstanding acting by written consent.

Special Stockholder Meetings

Our certificate of incorporation provides that, subject to the rights of the holders of any series of our Preferred Stock, special meetings of our stockholders may be called at any time by or at the direction of our board of directors or any holder of our Common Stock.

Stockholder Action by Written Consent

Pursuant to Section 228 of the DGCL, any action required or permitted to be taken at any annual or special meeting of the stockholders may be taken without a meeting, without prior notice and without a vote if a consent or consents in writing, setting forth the action so taken, is/are signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares of stock entitled to vote thereon were present and voted and such written consent or consents is/are delivered in accordance with Section 228 of the DGCL, unless our certificate of incorporation provides otherwise. Our certificate of incorporation permits holders of our Common Stock to act by written consent if a consent or consents, setting forth the action so taken, are signed by holders of our Common Stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and is delivered to the Company in the manner required by Section 228 of the DGCL.

Choice of Forum

Unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware (the “Court of Chancery”) will, to the fullest extent permitted by law, be the sole and exclusive forum for:

(i) any derivative action or proceeding brought on our behalf;

22

(ii) any action asserting a claim of breach of a fiduciary duty owed by any of our current or former directors, officers, other employees or stockholders to us or our stockholders;

(iii) any action asserting a claim arising pursuant to any provision of the DGCL, our certificate of incorporation or the bylaws or as to which the DGCL confers jurisdiction on the Court of Chancery; or

(iv) any action asserting a claim related to or involving us that is governed by the internal affairs doctrine, except for, as to each of (i) through (iv) above, any claim as to which the Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten (10) days following such determination), which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, or for which the Court of Chancery does not have subject matter jurisdiction. The exclusive forum provision also provides that it will not apply to claims arising under the Securities Act, the Exchange Act or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction, for which the federal district courts of the United States of America will be the exclusive forum for the resolution of such claims. Stockholders cannot waive, and will not be deemed to have waived under the exclusive forum provision, our compliance with the federal securities laws and the rules and regulations thereunder. However, the enforceability of similar forum provisions in other corporations’ certificates of incorporation have been challenged in legal proceedings and it is possible that a court could find these types of provisions to be unenforceable.

DESCRIPTION OF DEPOSITARY SHARES

The following outlines some of the general terms and provisions of the depositary shares. Further terms of the depositary shares and the applicable deposit agreement will be stated in the applicable prospectus supplement. The following description and any description of the depositary shares in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the deposit agreement, a form of which has been or will be filed as an exhibit to the registration statement of which this prospectus forms a part.

The particular terms of the depositary shares offered by any prospectus supplement and the extent to which the general provisions described below may apply to such depositary shares will be outlined in the applicable prospectus supplement.

General

AHL may choose to offer fractional interests in debt securities or fractional shares of Preferred Stock. AHL may issue fractional interests in debt securities or Preferred Stock, as the case may be, in the form of depositary shares. Each depositary share would represent a fractional interest in a security of a particular series of debt securities, a fraction of a shares of a particular series of Preferred Stock, as the case may be, and would be evidenced by a depositary receipt.

AHL will deposit the debt securities or Preferred Stock represented by depositary shares under a deposit agreement between AHL and a depositary which will be named in the applicable prospectus supplement. Subject to the terms of the deposit agreement, as an owner of a depositary share, you will be entitled, in proportion to the applicable fraction of a debt security or share of Preferred Stock represented by the depositary share, to all the rights and preferences of the debt security or Preferred Stock, as the case may be, represented by the depositary share, including, as the case may be, interest, dividend, voting, conversion, redemption, sinking fund, repayment at maturity, subscription and liquidation rights.

Interest, Dividends and Other Distributions

The depositary will distribute all payments of interest, cash dividends or other cash distributions received on the debt securities or Preferred Stock, as the case may be, to you in proportion to the number of depositary shares that you own. In the event of a distribution other than in cash, the depositary will distribute property received by it to you in an equitable manner, unless the depositary determines that it is not feasible to make a distribution. In that case, the depositary may sell the property and distribute the net proceeds from the sale to you.

Redemption of Depositary Shares

If debt securities or shares of Preferred Stock represented by depositary shares is redeemed, the depositary will redeem your depositary shares from the proceeds received by the depositary resulting from the redemption. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per debt security or share of Preferred Stock, as the case may be, payable in relation to the redeemed series of debt securities or Preferred Stock. Whenever AHL redeems debt securities or shares of Preferred Stock held by the depositary, the depositary will redeem, as of the same redemption date, the number of depositary shares representing, as the case may be, fractional interests in the debt securities or shares of Preferred Stock redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot, proportionately or by any other equitable method as the depositary may determine.

Exercise of Rights under the Indentures or Voting the Preferred Stock

Upon receipt of notice of any meeting at which you are entitled to vote, or of any request for instructions or directions from you as holder of fractional interests in debt securities or shares of Preferred Stock, the depositary

24

will mail to you the information contained in that notice. Each record holder of the depositary shares on the record date will be entitled to instruct the depositary how to give instructions or directions with respect to the debt securities represented by that holder’s depositary shares or how to vote the amount of the Preferred Stock represented by that holder’s depositary shares. The record date for the depositary shares will be the same date as the record date for the debt securities or Preferred Stock, as the case may be. The depositary will endeavor, to the extent practicable, to give instructions or directions with respect to the debt securities or to vote the amount of the Preferred Stock, as the case may be, represented by the depositary shares in accordance with those instructions.

AHL will agree to take all reasonable action which the depositary may deem necessary to enable the depositary to do so. The depositary will abstain from giving instructions or directions with respect to your fractional interests in the debt securities or voting shares of the Preferred Stock, as the case may be, if it does not receive specific instructions from you.

Amendment and Termination of the Deposit Agreement

AHL and the depositary may amend the form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement at any time. However, any amendment which materially and adversely affects the rights of the holders of the depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding.

The deposit agreement will terminate if:

• all outstanding depositary shares have been redeemed;

• if applicable, the debt securities and the Preferred Stock represented by depositary shares have been repaid in full; or

• if applicable, there has been a final distribution in respect of the Preferred Stock, including in connection with the liquidation, dissolution or winding-up of AHL, and the distribution proceeds have been distributed to you.

Resignation and Removal of Depositary

The depositary may resign at any time by delivering to AHL notice of its election to do so. AHL also may, at any time, remove the depositary. Any resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of such appointment. AHL must appoint the successor depositary within 60 days after delivery of the notice of resignation or removal. The successor depositary must be a bank or trust company having its principal office in the United States and having total assets of not less than $1,000,000,000.

Charges of Depositary

AHL will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. AHL will pay charges of the depositary in connection with the initial deposit of the debt securities or shares of Preferred Stock, as the case may be, and issuance of depositary receipts, all withdrawals of depositary shares of debt securities or shares of Preferred Stock, as the case may be, by you and any repayment or redemption of the debt securities or Preferred Stock, as the case may be. You will pay other transfer and other taxes and governmental charges, as well as the other charges that are expressly provided in the deposit agreement to be for your account.

Miscellaneous

The depositary will forward all reports and communications from AHL which are delivered to the depositary and which AHL is required or otherwise determines to furnish to holders of debt securities or shares of Preferred

25

Stock, as the case may be. Neither AHL nor the depositary will be liable under the deposit agreement to you other than for its gross negligence, willful misconduct or bad faith. Neither AHL nor the depositary will be obligated to prosecute or defend any legal proceedings relating to any depositary shares, debt securities or shares of Preferred Stock unless satisfactory indemnity is furnished. AHL and the depositary may rely upon written advice of counsel or accountants, or upon information provided by persons presenting debt securities or shares of Preferred Stock for deposit, you or other persons believed to be competent and on documents which AHL and the depositary believe to be genuine. Computershare Trust Company, N.A. is the transfer agent and registrar and Computershare Inc. is the dividend disbursing agent and redemption agent for the depositary shares representing an interest in the Series A Preferred Stock, the Series B Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and the Series E Preferred Stock.

PLAN OF DISTRIBUTION

Initial Offering and Sale of Securities

We may sell the securities being offered hereby in one or more of the following ways from time to time:

• to underwriters or dealers for resale to the public or to institutional investors;

• directly to institutional investors; or

• through agents to the public or to institutional investors.

In addition, the manner in which we may sell some or all of the securities covered by this prospectus includes, without limitation, through:

• a block trade in which a broker-dealer will attempt to sell as agent, but may position or resell a portion of the block, as principal, in order to facilitate the transaction;

• purchases by a broker-dealer, as principal, and resale by the broker-dealer for its account;

• ordinary brokerage transactions and transactions in which a broker solicits purchasers; or

• privately negotiated transactions.

The prospectus supplement with respect to each series of securities will state the terms of the offering of the securities, including:

• the name or names of any underwriters or agents;

• the purchase price of the securities and the proceeds to be received by us from the sale;

• any underwriting discounts or agency fees and other items constituting underwriters’ or agents’ compensation;

• any initial public offering price;

• any discounts or concessions allowed or reallowed or paid to dealers; and

• any securities exchange on which the securities may be listed.

If we use underwriters in the sale, the securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions, including:

• negotiated transactions;

• at a fixed public offering price or prices, which may be changed;

• at market prices prevailing at the time of sale;

• at prices related to prevailing market prices; or

• at negotiated prices.

The securities may also be offered and sold, if so indicated in the prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as our agents. The prospectus supplement will identify any remarketing firm and will describe the terms of its agreement, if any, with us and its compensation.

Unless otherwise stated in a prospectus supplement, the obligations of the underwriters to purchase any securities will be conditioned on customary closing conditions and the underwriters will be obligated to purchase all of such series of securities, if any are purchased.

30

If we sell the securities directly or through agents we designate, we will identify any agent involved in the offering and sale of the securities and will list any commissions payable by us to the agent in the accompanying prospectus supplement. Unless indicated otherwise in the prospectus supplement, any such agent will be acting on a best efforts basis to solicit purchases for the period of its appointment.

We may authorize agents, underwriters or dealers to solicit offers by certain institutional investors to purchase securities and provide for payment and delivery on a future date specified in an accompanying prospectus supplement. We will describe any such arrangement in the prospectus supplement. Any such institutional investor may be subject to limitations on the minimum amount of securities that it may purchase or on the portion of the aggregate principal amount of such securities that it may sell under such arrangements. Institutional investors from which such authorized offers may be solicited include:

• commercial and savings banks;

• insurance companies;

• pension funds;

• investment companies;

• educational and charitable institutions; and

• such other institutions as we may approve.

Underwriters, dealers, agents and remarketing firms may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which the underwriters, dealers, agents and remarketing firms may be required to make. Underwriters, dealers, agents and remarketing agents may be customers of, engage in transactions with, or perform services for us and/or our affiliates in the ordinary course of business.

Each series of securities will be a new issue of securities and will have no established trading market. The securities may or may not be listed on a national securities exchange. Any underwriters to whom we sell securities for public offering and sale may make a market in the securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice.

Sales by Selling Securityholders

Selling securityholders may use this prospectus in connection with resales of the securities. The applicable prospectus supplement will identify the selling securityholders and the terms of the securities to be resold. Selling securityholders may be deemed to be underwriters in connection with the securities they resell and any profits on the sales may be deemed to be underwriting discounts and commissions under the Securities Act. The selling securityholders will receive all the proceeds from the sale of the securities. We will not receive any proceeds from sales by selling securityholders.
