KAHC KKR Acquisition Holdings I Corp

On behalf of the board of directors (the “Board”) of KKR Acquisition Holdings I Corp. (the “Company”), I invite you to attend our Special Meeting of Stockholders (the “Special Meeting”). The Special Meeting will be held at       Eastern Time on      , 2022. The Company will be holding the Special Meeting via live webcast. You will be able to attend the Special Meeting, vote and submit your questions online before the Special Meeting by visiting https://www.cstproxy.com/kkracqholdingsi/2022. The Notice of Special Meeting of Stockholders, the proxy statement and the proxy card that each accompany this letter are also available at https://www.cstproxy.com/kkracqholdingsi/2022.

As discussed in the enclosed proxy statement, the purpose of the Special Meeting is to consider and vote upon the following proposals:

Approval of both the Charter Amendment Proposal and Trust Amendment Proposal is a condition to the implementation of the Extension Period. The Adjournment Proposal will only be presented at the Special Meeting if there are not sufficient votes to approve the Charter Amendment Proposal and the Trust Amendment Proposal.

Each of the Charter Amendment Proposal, the Trust Amendment Proposal, and the Adjournment Proposal is more fully described in the accompanying proxy statement.

Only holders of record of our common stock at the close of business on November 10, 2022 are entitled to notice of the Special Meeting and to vote at the Special Meeting and any adjournments or postponements of the Special Meeting.

Our Board has approved the Charter Amendment Proposal, the Trust Amendment Proposal and the Adjournment Proposal, and recommends that stockholders vote in favor of each proposal. Approval of the Charter Amendment Proposal and the Trust Amendment Proposal requires the affirmative vote of holders of at least 65% of our outstanding shares of common stock entitled to vote thereon. Approval of the Adjournment Proposal requires the affirmative vote of holders of a majority of the votes cast by stockholders represented via the remote platform or by proxy at the Special Meeting and entitled to vote thereon.

In connection with the Charter Amendment Proposal, Holders (“public stockholders”) of the Company’s Class A common stock, $0.0001, par value per share (“public shares”), may elect to redeem their public shares (the “Election”) for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest not previously released to the Company to pay franchise and income taxes, divided by the number

of then outstanding public shares, regardless of whether or how such public stockholders vote on the proposals at the Special Meeting; however redemption payments will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval.

You are not being asked to vote on any business combination at this time. If the Charter Amendment Proposal and the Trust Amendment Proposal are approved by the requisite vote of stockholders, the remaining holders of public shares will retain their right to redeem their public shares if and when the initial business combination is submitted to stockholders for approval, subject to any limitations set forth in our charter. In addition, public stockholders who do not make the Election will be entitled to have their public shares redeemed for cash if the Company has not completed the initial business combination before the expiration of the Extension Period, subject to any limitations set forth in our charter.

If the Charter Amendment Proposal and Trust Amendment Proposal are approved and the Extension is implemented, then in accordance with the Company’s Trust Agreement, the Company’s trust account will not be liquidated (other than to effectuate the redemptions described above) until the earlier of (a) receipt by the trustee of a termination letter (in accordance with the terms of the trust agreement) or (b) the expiration of the Extension Period.

To exercise your redemption rights, you must tender your shares to Continental, the Company’s transfer agent, at least two business days prior to the Special Meeting. You may tender your shares by delivering your shares electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal At Custodian) system. If you hold your shares in street name, you will need to instruct your bank, broker or other nominee to withdraw the shares from your account in order to exercise your redemption rights. The redemption rights include the requirement that a stockholder must identify itself in writing as a beneficial holder and provide its legal name, phone number, and address in order to validly redeem its public shares.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests and, thereafter, with our consent. Furthermore, if a holder of a public share delivers the certificate representing such holder’s shares in connection with an Election and subsequently decides prior to the applicable date not to elect to exercise such rights, such holder may request that the transfer agent return the certificate (physically or electronically).

The Company estimates that the per-share pro rata portion of the trust account will be approximately $    at the time of the Special Meeting. The closing price of the Company’s common stock on    , 2022 was $   . Accordingly, if the market price were to remain the same until the date of the Special Meeting, exercising redemption rights would result in a public stockholder receiving $    more for each share than if such stockholder sold the shares in the open market. The Company cannot assure stockholders that they will be able to sell their public shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such stockholders wish to sell their public shares.

The Company reserves the right at any time to cancel the Special Meeting and not to submit the Charter Amendment Proposal or the Trust Amendment Proposal to stockholders. In addition, notwithstanding stockholder approval of the Charter Amendment Proposal and the Trust Amendment Proposal, our Board will retain the right to abandon and not implement the Charter Amendment or Trust Amendment at any time before the effectiveness thereof without any further action by our stockholders.

After careful consideration of all relevant factors, the Board has determined that each of the proposals are advisable and recommends that you vote or give instruction to vote “FOR” such proposals.

Enclosed is the proxy statement containing detailed information concerning the Special Meeting, the Charter Amendment Proposal and the Trust Amendment Proposal. Whether or not you plan to virtually participate in the Special Meeting, we urge you to read this material carefully and vote your shares.

WHETHER OR NOT YOU PLAN TO PARTICIPATE VIRTUALLY IN THE SPECIAL MEETING, IT IS REQUESTED THAT YOU INDICATE YOUR VOTE ON THE ISSUES INCLUDED ON THE ENCLOSED PROXY AND DATE, SIGN AND MAIL IT IN THE ENCLOSED SELF-ADDRESSED ENVELOPE WHICH REQUIRES NO POSTAGE IF MAILED IN THE UNITED STATES OF AMERICA OR SUBMIT YOUR PROXY THROUGH THE INTERNET AS PROMPTLY AS POSSIBLE.

IMPORTANT NOTICE REGARDING THE AVAILABILITY OF PROXY MATERIALS FOR THE SPECIAL MEETING OF STOCKHOLDERS TO BE HELD ON    , 2022. THIS PROXY STATEMENT TO THE STOCKHOLDERS WILL BE AVAILABLE AT HTTPS://WWW.CSTPROXY.COM/KKRACQHOLDINGSI/2022. WE ARE FIRST MAILING THESE MATERIALS TO OUR STOCKHOLDERS ON OR ABOUT    , 2022.

The purpose of the Charter Amendment and Trust Amendment is to provide the Sponsor with additional time during the Extension Period to effect a suitable initial business combination as well as to provide for additional flexibility to authorize a dissolution of the Company following the date of the Special Meeting and prior to the scheduled end of the Extension Period. The Board believes that it is in the best interests of our stockholders to provide the Company more time to identify and consummate the initial business combination. The Company intends to hold another stockholders meeting prior to the expiration of the Extension Period in order to seek stockholder approval of a potential business combination.

Approval of both the Charter Amendment Proposal and Trust Amendment Proposal is a condition to the implementation of the Extension Period.

The Company’s IPO prospectus and charter provided that the Company initially has until March 19, 2023 (the date which is 24 months after the consummation of the IPO) to complete the initial business combination. If both the Charter Amendment Proposal and the Trust Amendment Proposal are approved, the business combination period will be extended to December 19, 2023 (i.e., nine (9) months from the current termination date) and our Board will have the ability to elect to wind up our operations on an earlier date.

Our Board believes that it is in the best interests of our stockholders to provide for this extension and incremental flexibility. Upon preparation of a proxy statement in connection with a proposed business combination, the Company intends to hold another stockholders meeting prior to the expiration of the Extension Period in order to seek stockholder approval of the initial business combination.

Our Board believes stockholders will benefit from the Company consummating the initial business combination and is proposing the Charter Amendment and Trust Amendment to extend the date by which the Company must complete the initial business combination to the expiration of the Extension Period. Our Board also believes that stockholders will benefit from giving the Company the flexibility to authorize a dissolution following the date of the Special Meeting and prior to the scheduled end of the Extension Period if a suitable acquisition target does not emerge. Your vote in favor of the Charter Amendment Proposal and the Trust Amendment Proposal is required for the Company to implement the Charter Amendment and the Trust Amendment, respectively.

The Company’s existing charter provides that if the Company’s stockholders approve an amendment to the Company’s charter that would affect the substance or timing of the Company’s obligation to redeem shares of the Company’s Class A common stock issued in the IPO (the “public shares”) if the Company does not complete its initial business combination before March 19, 2023, the Company will provide holders of its public shares (“public stockholders”) with the opportunity to redeem all or a portion of their public shares upon such approval (the election for such a redemption, the “Election”) at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. The Company believes that this charter provision was included to protect the Company’s stockholders from having to sustain their investments for an unreasonably long period if the Company failed to find a suitable business combination in the timeframe contemplated by the initial charter. If you do not elect to redeem your public shares, you will retain the right to vote on any proposed initial business combination in the future and the right to redeem your public shares in connection with such initial business combination.

Our Board recommends that you vote in favor of the Charter Amendment Proposal and Trust Amendment Proposal but expresses no opinion as to whether you should redeem your public shares. Public stockholders may elect to redeem their public shares regardless of whether or how they vote on the proposals at the Special Meeting, however, redemption payments will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval.

All of the Company’s directors and their respective affiliates are expected to vote any common stock over which they have voting control (including any public shares owned by them) in favor of the proposals.

Our initial stockholders (and their permitted transferees) have entered into a letter agreement with us pursuant to which they have agreed to vote any shares owned by them in favor of any proposed initial business combination and to waive their redemption rights with respect to their shares of common stock in connection with (i) the completion of our initial business combination or (ii) a stockholder vote to approve an amendment to our charter (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within 24 months from the closing of the IPO or (B) with respect to any other material provision relating to stockholders’ rights or pre-initial business combination activity. The initial stockholders are not entitled to redeem the Founder Shares.

On the record date, the initial stockholders beneficially owned and were entitled to vote 34,500,000 Founder Shares, which represents 20% of the Company’s issued and outstanding common stock.

In addition, the Sponsor or the Company’s or a potential target’s executive officers or advisors, or any of their respective affiliates, may purchase public shares in privately negotiated transactions or in the open market prior to the Special Meeting, although they are under no obligation to do so. Any such purchases that are completed after the record date for the Special Meeting may include an agreement with a selling stockholder that such stockholder, for so long as it remains the record holder of the shares in question, will vote in favor of the Charter Amendment Proposal and Trust Amendment Proposal and/or will not exercise its redemption rights with respect to the shares so purchased. The purpose of such share purchases and other transactions would be to increase the likelihood that the proposal to be voted upon at the Special Meeting is approved by the requisite number of votes. In the event that such purchases do occur, the purchasers may seek to purchase shares from stockholders who would otherwise have voted against the Charter Amendment Proposal and Trust Amendment Proposal and elected to redeem their shares for a portion of the trust account. Any such privately negotiated purchases may be effected at purchase prices that are below or in excess of the per-share pro rata portion of the trust account. Any public shares held by or subsequently purchased by our affiliates may be voted in favor of the Charter Amendment Proposal and Trust Amendment Proposal. None of the Company’s Sponsor, directors, executive officers, advisors or their affiliates may make any such purchases when they are in possession of any material non-public information not disclosed to the seller or during a restricted period under Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Yes. After careful consideration of the terms and conditions of the proposal, the Board has determined that the proposal is in the best interests of the Company and its stockholders. The Board unanimously recommends that stockholders vote “FOR” the Charter Amendment Proposal and Trust Amendment Proposal.

Approval of each of the Charter Amendment Proposal and Trust Amendment Proposal will require the affirmative vote of holders of 65% of the Company’s outstanding common stock entitled to vote thereon.

The November 10, 2022 record date is earlier than the date of the Special Meeting. If you transfer your public shares after the record date but before the Special Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Special Meeting. If you transfer your shares of common stock prior to the record date, you will have no right to vote those shares at the Special Meeting.

Other than the Extension, until the expiration of the Extension Period as described in this proxy statement, the Company does not currently anticipate seeking any further extension to consummate the initial business combination.

If the Charter Amendment Proposal and Trust Amendment Proposal are not approved, and we do not consummate the initial business combination by March 19, 2023, we will be required to dissolve and liquidate our trust account by returning the then remaining funds in such account to the public stockholders.

The Company’s initial stockholders have waived their rights to participate in any liquidation distribution with respect to their Founder Shares. There will be no distribution from the trust account with respect to the Company’s warrants, which will expire worthless in the event we wind up.

Additionally, redemption payments for Elections in connection with this Special Meeting will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval.

Subject to the approval of the Charter Amendment Proposal and the Trust Amendment Proposal by the holders of 65% of the outstanding shares of the common stock entitled to vote thereon, the Company will file an amendment to the charter with the Secretary of State of the State of Delaware in the form of Annex A hereto and the Trust Amendment in the form of Annex B hereto will go into effect. The Company will remain a reporting company under the Exchange Act, and its units, common stock, and public warrants will remain publicly traded. The Company will then continue to work to identify and consummate the initial business combination prior to the expiration of the Extension Period, unless the Board determines that an earlier liquidation is in the best interests of the Company’s stockholders. However, the Company will not proceed with the Extension if the number of redemptions of our public shares causes us to have net tangible assets of less than $5,000,001 following approval of the Charter Amendment Proposal and Trust Amendment Proposal.

The Charter Amendment Proposal and the Trust Amendment Proposal must both be approved for the Extension Period to be implemented.

Yes, assuming you are a stockholder as of the record date and continue to hold your shares at the time of your Election (and subsequent redemption payment). However, redemption payments for Elections in connection with this Special Meeting will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval. If you do not redeem your public shares in connection with the Special Meeting, and you disagree with the initial business combination if and when it is proposed for a stockholder approval, you will retain your right to redeem your public shares upon consummation of the initial business combination, subject to any limitations set forth in the charter.

The Special Meeting will be held at     Eastern Time, on    , 2022, in virtual format. The Company’s stockholders may attend and vote at the Special Meeting by visiting https://www.cstproxy.com/kkracqholdingsi/2022 and entering the control number found on their proxy card. You may also attend the meeting telephonically by dialing (800) 450-7155 (toll-free within the United States and Canada) or (857) 999-9155 (outside of the United States and Canada, standard rates apply). The passcode for telephone access is 0142389#, but please note that you will not be able to vote or ask questions if you choose to participate telephonically. You will not be able to attend the Special Meeting physically. The online meeting format for the Special Meeting will enable full and equal participation by all our stockholders from any place in the world at little to no cost.

As a registered stockholder, you received a Proxy Card from Continental. The form contains instructions on how to attend the Special Meeting including the URL address, along with your control number. You will need your control number for access. If you do not have your control number, contact Continental at the phone number or e-mail address below. Continental support contact information is as follows: (917) 262-2373, or email proxy@continentalstock.com.

You can pre-register to attend the virtual meeting starting on    , 2022 at     Eastern Time (four (4) business days prior to the meeting date). Enter the URL address into your browser https://www.cstproxy.com/kkracqholdingsi/2022, enter your control number, name and email address. Once you pre-register you can vote or enter questions in the chat box. At the start of the meeting you will need to log in again using your control number and will also be prompted to enter your control number if you vote during the meeting.

Beneficial holders, who own their investments through a bank or broker, will need to contact Continental to receive a control number. If you plan to vote at the Special Meeting you will need to have a legal proxy from your bank or broker or if you would like to join and not vote Continental will issue you a guest control number with proof of ownership. Either way you must contact Continental for specific instructions on how to receive the control number. We can be contacted at the number or email address above. Please allow up to seventy-two (72) hours prior to the meeting for processing your control number.

If you do not have internet capabilities, you can listen only to the meeting by dialing (800) 450-7155 (toll-free), within the U.S. and Canada, or (857) 999-9155 (standard rates apply) outside the U.S. and Canada; when prompted enter the pin number 0142389#. This is listen only; you will not be able to vote or enter questions during the Special Meeting.

If you are a holder of record of Company common stock, you may vote virtually at the Special Meeting or by submitting a proxy for the Special Meeting. Whether or not you plan to attend the Special Meeting virtually, the Company urges you to vote by proxy to ensure your vote is counted. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope. You may still attend the Special Meeting and vote virtually if you have already voted by proxy.

If your shares of Company common stock are held in “street name” by a broker or other agent, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Special Meeting. However, since you are not the stockholder of record, you may not vote your shares virtually at the Special Meeting unless you first submit a legal proxy to Continental. Continental will then issue you a valid control number which will allow you to vote at the Special Meeting.

If you have submitted a proxy to vote your shares and wish to change your vote, you may do so by delivering a later-dated, signed proxy card prior to the date of the Special Meeting or by voting virtually at the Special Meeting. Attendance at the Special Meeting alone will not change your vote.

Votes will be counted by the inspector of election appointed for the Special Meeting, who will separately count “FOR” and “AGAINST” votes and abstentions for each proposal.

Under the rules governing banks and brokers who submit a proxy card with respect to shares held in street name, such banks and brokers have the discretion to vote on routine matters, but not on non-routine matters. The Charter Amendment Proposal, Trust Amendment Proposal and Adjournment Proposal are all “non-discretionary” (and non-routine) items. Thus, your broker can vote your shares with respect to “non-discretionary items” only if you provide instructions on how to vote. You should instruct your broker to vote your shares. Your broker can tell you how to provide these instructions.

A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if at least a majority of the outstanding shares of common stock on the record date are represented virtually or by proxy at the Special Meeting.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote virtually at the Special Meeting. Abstentions will be counted towards the quorum requirement. If there is no quorum, the chairman of the Special Meeting may adjourn the Special Meeting to another date.

Only holders of record of the Company’s common stock at the close of business on November 10, 2022, are entitled to have their vote counted at the Special Meeting and any adjournments or postponements thereof. On this record date, 138,000,000 shares of Class A common stock and 34,500,000 Founder Shares were outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name. If on the record date your shares or units were registered directly in your name with the Company’s transfer agent, Continental, then you are a stockholder of record. As a stockholder of record, you may vote virtually at the Special Meeting or vote by proxy. Whether or not you plan to attend the Special Meeting virtually, the Company urges you to fill out and return the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank. If on the record date your shares or units were held not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Special Meeting virtually. However, since you are not the stockholder of record, you may not vote your shares virtually at the Special Meeting unless you first submit a legal proxy to Continental. Continental will then issue you a valid control number which will allow you to vote at the Special Meeting. The failure to vote your shares (including by failing to provide your broker instructions as to how shares that you beneficially own in “street name”) will have the effect of a vote against the Charter Amendment Proposal and the Trust Amendment Proposal, but will have no effect on the Adjournment Proposal assuming a quorum is present.

The Company’s directors and executive officers have interests in the proposals that may be different from, or in addition to, your interests as a stockholder. See “The Special Meeting — Interests of our Sponsor, Directors and Officers.”

If the Charter Amendment Proposal or Trust Amendment Proposal is not approved and we do not identify and consummate an initial business combination by March 19, 2023, we will be required to dissolve and liquidate our trust account by returning the then remaining funds in such account to the public stockholders and the Company’s public warrants and Private Placement Warrants will expire worthless.

If both the Charter Amendment Proposal and Trust Amendment Proposal are approved, the Company will continue its efforts to identify and consummate its initial business combination until the expiration of the Extension Period and will retain the blank check company restrictions previously applicable to it, and the public warrants and Private Placement Warrants will remain outstanding in accordance with their terms.

If the Charter Amendment and the Trust Amendment are implemented, each public stockholder may seek to redeem all or a portion of his or her public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account to the approval of the Charter Amendment and the Trust Amendment, including interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. You will also be able to redeem your public shares in connection with any stockholder vote to approve the initial business combination, or if the Company has not consummated the initial business combination by the expiration of the Extension Period.

To demand redemption, you must ensure your bank or broker complies with the requirements identified herein, including submitting a written request that your shares be redeemed for cash to the transfer agent and delivering your shares to the transfer agent prior to 5:00 p.m. Eastern Time on    , 2022. You will only be entitled to receive cash in connection with a redemption of these shares if you continue to hold them until the effective date of the Charter Amendment, Trust Amendment and Election.

Pursuant to our charter, a public stockholder may request that the Company redeem all or a portion of such public stockholder’s public shares for cash if the Charter Amendment Proposal and Trust Amendment Proposal are approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Public stockholders may elect to redeem all or a portion of their public shares even if they vote for the Charter Amendment Proposal and Trust Amendment Proposal.

Through DTC’s DWAC (Deposit/Withdrawal at Custodian) System, this electronic delivery process can be accomplished by the stockholder, whether or not it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical stock certificate, a stockholder’s broker and/or clearing broker, DTC, and the Company’s transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $100 and the broker would determine whether or not to pass this cost on to the redeeming holder. It is the Company’s understanding that stockholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. The Company does not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical stock certificate. Such stockholders will have less time to make their investment decision than those stockholders that deliver their shares through the DWAC system. Stockholders who request physical stock certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to the vote on the Charter Amendment Proposal and Trust Amendment Proposal will not be redeemed for cash held in the trust account.

In the event that a public stockholder tenders its shares and decides prior to the vote at the Special Meeting that it does not want to redeem its shares, the stockholder may withdraw the tender. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the Special Meeting not to redeem your shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public stockholder tenders shares and the Charter Amendment Proposal and Trust Amendment Proposal are not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the stockholder promptly following the determination that the Charter Amendment Proposal and Trust Amendment Proposal will not be approved. The Company anticipates that a public stockholder who tenders shares for redemption in connection with the vote to approve the Charter Amendment Proposal and the Trust Amendment Proposal would receive payment of the redemption price for such shares soon after the completion of the Charter Amendment and Trust Amendment. The transfer agent will hold the certificates of public stockholders that make the election until such shares are redeemed for cash or returned to such stockholders.

No. Holders of outstanding public units must separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares.

If you hold units registered in your own name, you must deliver the certificate (physically or electronically) for such units to Continental, our transfer agent, with written instructions to separate such units into public shares and

public warrants. This must be completed far enough in advance to permit the mailing of the public share certificates back to you so that you may then exercise your redemption rights upon the separation of the units into public shares and public warrants. See “How do I redeem my public shares?” above.

You may receive more than one set of voting materials, including multiple copies of this proxy statement and multiple proxy cards or voting instruction cards, if your shares are registered in more than one name or are registered in different accounts. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your Company shares.

The Company will pay for the entire cost of soliciting proxies. The Company has engaged Morrow Sodali LLC (“Morrow”) to assist in the solicitation of proxies for the Special Meeting. The Company has agreed to pay Morrow’s customary fees of approximately $42,500, plus disbursements, and indemnify Morrow against certain damages, expenses, liabilities or claims relating to its services as the Company’s proxy solicitor. In addition to these mailed proxy materials, our directors and executive officers may also solicit proxies in person, by telephone or by other means of communication. These parties will not be paid any additional compensation for soliciting proxies. The Company may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners. While the payment of these expenses will reduce the cash available to us to consummate an initial business combination if the Extension is approved, we do not expect such payments to have a material effect on our ability to consummate an initial business combination.

We will announce preliminary voting results at the Special Meeting. The final voting results will be tallied by the inspector of election and published in the Company’s Current Report on Form 8-K, which the Company is required to file with the SEC within four (4) business days following the Special Meeting.

If you have questions about the proposals or if you need additional copies of the proxy statement or the enclosed proxy card you should contact the Company’s proxy solicitor at:

You may also obtain additional information about the Company from documents filed with the SEC by following the instructions in the section entitled “Where You Can Find More Information.”

We have based these forward-looking statements on our current expectations and projections about future events. These forward-looking statements are subject to known and unknown risks, uncertainties and assumptions about us that may cause our actual results, levels of activity, performance or achievements to be materially different from any future results, levels of activity, performance or achievements expressed or implied by such forward-looking statements.

The forward-looking statements contained in this proxy statement are based on our current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control) or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. Factors that might cause or contribute to such a discrepancy include, but are not limited to, those described under “Risk Factors” in this proxy statement and “Item 1A.

Risk Factors” of our Annual Report and in other reports we file with the SEC. Our business, financial condition or results of operations could also be materially and adversely affected by additional factors that apply to all companies generally, as well as other risks that are not currently known to us or that we currently view to be immaterial. In any such case, the trading price of our securities could decline and you may lose all or part of your original investment. While we attempt to mitigate known risks to the extent we believe to be practicable and reasonable, we can provide no assurance, and we make no representation, that our mitigation efforts will be successful.

We may not be able to find a suitable target business and complete the initial business combination by the expiration of the Extension Period, even if the Charter Amendment Proposal and the Trust Amendment Proposal are approved by our stockholders. Our ability to complete the initial business combination may be negatively impacted by general market conditions, volatility in the capital and debt markets and the other risks described herein, in our Annual Report and in other reports that we file with the SEC. If we have not completed the initial business combination within such time period, we will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds in the trust account (net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish the public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and our Board, liquidate and dissolve, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Additionally, there will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless in the event of our winding up.

On August 16, 2022, the Inflation Reduction Act of 2022 (the “IR Act”) was signed into federal law. The IR Act provides for, among other things, a new U.S. federal (non-deductible) 1% excise tax on certain repurchases (including redemptions) of shares of stock by publicly traded “covered corporations.” For these purposes a “covered corporation” includes entities treated as U.S. corporations under the Internal Revenue Code (including as a result of the “inversion” rules) and in certain circumstances, U.S. subsidiaries of publicly traded non-U.S. corporations. The excise tax is imposed directly on the repurchasing corporation itself, not its stockholders from which shares are repurchased. The amount of the excise tax is generally equal to 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of determining the fair market value of the repurchased shares, a covered corporation is permitted to reduce the value of the repurchased shares by the fair market value of certain new stock issuances made in the same taxable year. In addition, there are a limited number of other exclusions that may apply to the excise tax. The Treasury Department has been given broad authority to provide regulations and other guidance to implement the excise tax and prevent the abuse or avoidance of the excise tax. The excise tax applies only to repurchases that occur after December 31, 2022.

As described under “The Special Meeting — Redemption Rights,” if the deadline for us to complete an initial business combination (currently March 19, 2023) is extended, our public stockholders will have the right to require us to redeem their public shares. Because any redemption that occurs as a result of the Extension would occur before December 31, 2022, we would not be subject to the excise tax as a result of any redemptions in connection with the Extension. However, any redemption or other repurchase that occurs after December 31, 2022, in connection with an initial business combination, our liquidation or otherwise, may be subject to the excise tax. Whether and to what extent we would be subject to the excise tax in respect of taxable years beginning after December 31, 2022 will

depend on a number of factors, including (i) the fair market value of shares of our stock that are redeemed or otherwise repurchased by us in the applicable tax year, (ii) the nature and amount of any “PIPE” or other equity issuances that occur in connection with the initial business combination (or otherwise issued not in connection with the initial business combination but issued within the same taxable year in which the initial business combination occurs), (iii) the structure of any initial business combination as it pertains to shares of our stock and (iv) the content of regulations and other guidance from the U.S. Department of the Treasury in respect of the excise tax and its implementation. The excise tax could cause a reduction in the cash available on hand to complete an initial business combination, could otherwise impact our ability to complete an initial business combination and/or could negatively impact stockholders who exercise their redemption rights after December 31, 2022.

We are a Delaware-incorporated blank check company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses.

We are sponsored by KKR & Co. Inc., a Delaware corporation (together with its subsidiaries, but excluding the Sponsor for purposes of this proxy statement, referred to as “KKR”) in partnership with Glenn Murphy, our Chief Executive Officer and Executive Chairman. We believe that the combined resources and expertise of KKR and Mr. Murphy will provide us a strong competitive advantage as we source, diligence and operate our future business combination, providing a differentiated value-creation opportunity for our stockholders.

An investment in us is not an investment in KKR, in any investment funds, vehicles and accounts advised, managed or sponsored by KKR (“KKR Funds”), in any other member of KKR, the KKR Funds and their affiliates (excluding the Sponsor and KKR portfolio companies, the “KKR Group”) or in FIS Holdings, LTD and its affiliates (excluding the Sponsor, “FIS Holdings”). No employee of the KKR Group or FIS Holdings will be a member of our management team, even to the extent he or she is involved in our affairs, unless our Board expressly names such employee as an officer of the Company. Our Sponsor, KKR and FIS Holdings will not be providing investment advisory services to us, and we are not an investment advisory client of KKR, FIS Holdings or our Sponsor under the Investment Advisers Act of 1940.

Although we have reviewed a significant number of opportunities for our initial business combination, and we continue to search for a transaction in the best interests of our stockholders, the Board currently believes that there will not be sufficient time before March 19, 2023 (i.e., 24 months from the consummation of the IPO) to complete an initial business combination. Accordingly, the Board believes that in order to be able to both consummate an initial business combination and allow for current holders of public shares to make the Election, we will need to implement the Charter Amendment and the Trust Amendment.

Approximately $1.38 billion in proceeds from our IPO, the simultaneous sale of warrants in a private placement transaction, and interest income are being held in our trust account in the United States maintained by Continental, acting as trustee. The proceeds held in the trust account may only be invested in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act of 1940 (as amended, the “Investment Company Act”), having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Pursuant to the trust agreement, the trustee is not permitted to invest in other securities or assets. The trust account is intended as a holding place for funds pending the earliest to occur of: (i) the completion of our initial business combination; (ii) the redemption of any public shares properly submitted in connection with a stockholder vote to amend our charter (A) to modify the substance or timing of our obligation to allow redemption in connection with our initial business combination or to redeem 100% of our Public Shares if we do not complete our initial business combination within 24 months from the closing of the IPO, subject to extension, or (B) with respect to any other material provision relating to stockholders’ rights or pre-initial business combination activity; or (iii) absent an initial business combination within 24 months from the closing of the IPO or during any extension period, our return of the funds held in the trust account to our public stockholders as part of our redemption of the public shares.

Our Sponsor, directors and officers have interests in the proposals that may be different from, or in addition to, your interests as a stockholder. These interests include ownership of Founder Shares and warrants that may become exercisable in the future and the possibility of future compensatory arrangements. See the section entitled “The Special Meeting — Interests of our Sponsor, Directors and Officers.”

You are not being asked to vote on any business combination at this time. If the Charter Amendment and Trust Amendment are implemented and you do not elect to redeem your public shares, provided that you are a stockholder on the record date for a meeting to consider the initial business combination, you will be entitled to vote on the initial business combination if and when it is submitted to stockholders and will retain the right to redeem your public shares for cash in the event the initial business combination is approved and completed or we have not consummated a business combination by the expiration of the Extension Period, subject to the terms of the charter.

The enclosed proxy is solicited by the Board in connection with the Special Meeting to be held on    , 2022 at     Eastern Time for the purposes set forth in the accompanying Notice of Meeting. The Company will be holding the Special Meeting via live webcast. You will be able to attend the Special Meeting, vote and submit your questions online before the Special Meeting by visiting https://www.cstproxy.com/kkracqholdingsi/2022.

At the Special Meeting, you will be asked to consider and vote upon the following matters:

The Adjournment Proposal will only be presented at the Special Meeting if there are not sufficient votes to approve the Charter Amendment Proposal and the Trust Amendment Proposal.

The Charter Amendment Proposal and the Trust Amendment Proposal are essential to the overall implementation of the Board’s plan to extend the date by which the Company has to complete the initial business combination as well as to provide the Board with additional flexibility to authorize a dissolution of the Company and liquidate the trust account following the date of the Special Meeting but prior to December 19, 2023 if it determines such action is in the best interests of the stockholders.

You are not being asked to vote on any business combination at this time. If the Charter Amendment and Trust Amendment proposals are implemented and you do not elect to redeem your public shares now, you will retain the right to vote for the initial business combination if and when it is submitted to stockholders and the right to redeem your public shares for cash in the event a business combination is approved and completed or the Company has not consummated the business combination during the Extension Period, subject to the terms of the charter.

Public stockholders may elect to redeem their public shares for their pro rata portion of the funds available in the trust account in connection with the Charter Amendment Proposal regardless of whether or how such public stockholders vote with respect to the Charter Amendment Proposal. However, the Company will not proceed with the Charter Amendment Proposal and the Trust Amendment Proposal if the redemption of public shares in connection therewith would cause the Company to have net tangible assets of less than $5,000,001. Additionally, redemption payments for Elections in connection with this Special Meeting will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval. If the Charter Amendment Proposal and Trust Amendment Proposal are approved by the requisite vote of stockholders, the remaining public stockholders will retain their right to redeem their public shares for their pro rata portion of the funds available in the trust account when the initial business combination is submitted to the stockholders. Furthermore, if the Charter Amendment Proposal and the Trust Amendment Proposal are approved and the Extension is implemented, then in accordance with the terms of Trust Agreement, as amended, the trust account will not be liquidated (other than to effectuate the redemptions) until the earlier of (a) receipt by the trustee of a termination letter (in accordance with the terms of the Trust Agreement) or (b) the expiration of Extension Period.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with our consent. Furthermore, if a holder of a public share delivered the certificate representing such holder’s shares in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, such holder may request that the transfer agent return the certificate (physically or electronically).

The withdrawal of funds from the trust account in connection with the Election will reduce the amount held in the trust account following the redemption, and the amount remaining in the trust account may be significantly reduced from the approximately $    million that was in the trust account as of    , 2022.

If the Charter Amendment Proposal and the Trust Amendment Proposal are not approved and we do not consummate an initial business combination by March 19, 2023, in accordance with our charter, we will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds in the trust account (net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish the public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and our Board, liquidate and dissolve, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. The Company’s warrants will expire worthless.

The approval of the Charter Amendment Proposal and the Trust Amendment Proposal requires the affirmative vote of the holders of at least 65% of the outstanding shares of the Company’s common stock entitled to vote thereon. Approval of the Adjournment Proposal requires the affirmative vote of holders of a majority of the votes cast by stockholders represented via the remote platform or by proxy at the Special Meeting and entitled to vote thereon. Our Board will abandon and not implement the Charter Amendment Proposal or the Trust Amendment Proposal unless our stockholders approve both the Charter Amendment Proposal and the Trust Amendment Proposal. Notwithstanding stockholder approval of the Charter Amendment Proposal and the Trust Amendment Proposal, our Board will retain the right to abandon and not implement the Charter Amendment or Trust Amendment at any time before the effectiveness thereof without any further action by our stockholders.

Only holders of record of our common stock at the close of business on November 10, 2022 are entitled to notice of the Special Meeting and to vote at the Special Meeting and any adjournments or postponements of the Special Meeting.

After careful consideration of all relevant factors, the Board has determined that each of the proposals are advisable and recommends that you vote or give instruction to vote “FOR” such proposals.

The record date with respect to this solicitation is the close of business on November 10, 2022 and only stockholders of record at that time will be entitled to vote at the Special Meeting and any adjournments or postponements thereof.

The shares of common stock represented by all validly executed proxies received in time to be taken to the Special Meeting and not previously revoked will be voted at the meeting. This proxy may be revoked by the stockholder at any time prior to its being voted by filing with the Company either a notice of revocation or a duly executed proxy bearing a later date. We intend to release this proxy statement and the enclosed proxy card to our stockholders on or about    , 2022.

Holders of shares of our common stock do not have appraisal rights under Delaware law or under the governing documents of the Company in connection with this solicitation.

The number of outstanding shares of common stock entitled to vote at the Special Meeting is 138,000,000 public shares and 34,500,000 Founder Shares. Each share of common stock is entitled to one vote. The presence represented by virtual attendance or by proxy at the Special Meeting of a majority of the number of outstanding shares of common stock, will constitute a quorum. There is no cumulative voting. Shares that abstain will be treated as present for quorum purposes on all matters.

Holders of shares of our common stock that are held in street name must instruct their bank or brokerage firm that holds their shares how to vote their shares. We believe that each of the proposals is a “non-discretionary” matter,

and therefore, banks or brokerages cannot use discretionary authority to vote shares on Charter Amendment Proposal, Trust Amendment Proposal or Adjournment Proposal if they have not received instructions from their clients and there will not be any broker non-votes at the Special Meeting. Please submit your vote instruction form so your vote is counted.

Abstentions will count as a vote against the first two proposals, but will not have an effect on the Adjournment Proposal assuming a quorum is present. The failure to vote on Charter Amendment Proposal and the Trust Amendment Proposal will have the effect of a vote “AGAINST” each such proposal, but will have no effect on the Adjournment Proposal assuming a quorum is present.

The chairman of the meeting may adjourn the meeting whether or not there is a quorum, to reconvene at the same or some other place and may adjourn the meeting from time to time until a quorum shall attend.

Each share of our common stock that you own in your name entitles you to one vote on each of the proposals for the Special Meeting. Your proxy card shows the number of shares of our common stock that you own.

Your proxy is being solicited by our Board on the proposals being presented to stockholders at the Special Meeting. You may contact Morrow, our proxy solicitor at:

In addition to these mailed proxy materials, our directors and officers may also solicit proxies in person, by telephone or by other means of communication. Some banks and brokers have customers who beneficially own

public shares listed of record in the names of nominees and we intend to request banks and brokers to solicit such customers and will reimburse them for their reasonable out-of-pocket expenses for such solicitations.

Unless we have received contrary instructions, we may send a single copy of this proxy statement to any household at which two or more stockholders reside if we believe the stockholders are members of the same family. This process, known as “householding,” reduces the volume of duplicate information received at any one household and helps to reduce our expenses. However, if stockholders prefer to receive multiple sets of our disclosure documents at the same address this year or in future years, the stockholders should follow the instructions described below. Similarly, if an address is shared with another stockholder and together both of the stockholders would like to receive only a single set of our disclosure documents, the stockholders should follow these instructions:

When you consider the recommendation of our Board, you should keep in mind that our Sponsor, directors and officers have interests that may be different from, or in addition to, your interests as a stockholder. These interests include, among other things, the interests listed below:

Pursuant to our currently existing charter, our public stockholders will be provided with the opportunity to redeem their public shares upon the approval of the Charter Amendment, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, divided by the number of then outstanding public shares (if the redemption of public shares in connection therewith would not cause the Company to have net tangible assets of less than $5,000,001). If your redemption request is properly made and the Charter Amendment is approved, these

shares will cease to be outstanding and will represent only the right to receive such amount. For illustrative purposes, based on funds in the trust account of approximately $    million on    , 2022, the estimated per share redemption price would have been approximately $   . Public stockholders may elect to redeem their public shares regardless of whether or how they vote on the proposals at the Special Meeting, but redemption payments for Elections in connection with this Special Meeting will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval.

In order to exercise your redemption rights, you must:

and

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests (and submitting shares to the transfer agent) and thereafter, with our consent. If you delivered your shares for redemption to our transfer agent and decide within the required timeframe not to exercise your redemption rights, you may request that our transfer agent return the shares. You may make such request by contacting our transfer agent at the phone number or address listed above.

Prior to exercising redemption rights, stockholders should verify the market price of our common stock, as they may receive higher proceeds from the sale of their common stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. We cannot assure you that you will be able to sell your shares of our common stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in our common stock when you wish to sell your shares.

If you exercise your redemption rights and the redemption is effectuated, your shares of our common stock will cease to be outstanding and will only represent the right to receive a pro rata share of the aggregate amount on deposit in the trust account. You will no longer own those shares and will have no right to participate in, or have any interest in, the future growth of the Company, if any. You will be entitled to receive cash for these shares only if you properly and timely request redemption.

If the Charter Amendment Proposal and the Trust Amendment Proposal are not approved and we do not consummate the initial business combination by March 19, 2023, we will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds in the trust account (net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding public shares, which redemption will completely extinguish the public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to

the approval of the remaining stockholders and our Board, liquidate and dissolve, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. Our warrants to purchase common stock will expire worthless.

Holders of outstanding units must separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares.

If you hold units registered in your own name, you must deliver to Continental written instructions to separate such units into public shares and public warrants. This must be completed far enough in advance so that you may then exercise your redemption rights with respect to the public shares upon the separation of the units into public shares and public warrants.

If a broker, dealer, commercial bank, trust company or other nominee holds your units, you must instruct such nominee to separate your units. Your nominee must send written instructions to Continental. Such written instructions must include the number of units to be split and the nominee holding such units. Your nominee must also initiate electronically, using DTC’s deposit withdrawal at custodian (DWAC) system, a withdrawal of the relevant units and a deposit of an equal number of public shares and public warrants. This must be completed far enough in advance to permit your nominee to exercise your redemption rights with respect to the public shares upon the separation of the units into public shares and public warrants. While this is typically done electronically the same business day, you should allow at least one full business day to accomplish the separation. If you fail to cause your public shares to be separated in a timely manner, you will likely not be able to exercise your redemption rights.

connection with a stockholder vote to approve an amendment to our charter such as the Charter Amendment. On the record date, the initial stockholders beneficially owned and were entitled to vote 34,500,000 Founder Shares, which represents 20% of the Company’s issued and outstanding common stock.

In connection with the Charter Amendment Proposal, public stockholders may elect to redeem their shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest not previously released to the Company to pay franchise and income taxes, divided by the number of then outstanding public shares, regardless of whether such public stockholders vote “FOR” or “AGAINST” the Charter Amendment Proposal or the Trust Amendment Proposal, and an Election can also be made by public stockholders who do not vote, or do not instruct their broker or bank how to vote, at the Special Meeting. Public stockholders may make an Election regardless of whether such public stockholders were holders as of the record date. However, redemption payments for Elections in connection with this Special Meeting will only be made if the Charter Amendment Proposal and the Trust Amendment Proposal receive the requisite stockholder approval. If the Charter Amendment Proposal and the Trust Amendment Proposal are approved by the requisite vote of stockholders, the remaining holders of public shares will retain their right to redeem their public shares if and when any initial business combination is submitted to the stockholders, subject to any limitations set forth in our charter, as amended by the Charter Amendment (as long as their election is made at least two (2) business days prior to the meeting at which the stockholders’ vote is sought). However, the Company will not proceed with the Charter Amendment if the redemption of public shares in connection therewith would cause the Company to have net tangible assets of less than $5,000,001. Each redemption of shares by our public stockholders will decrease the amount in our trust account, which held approximately $1.38 billion of marketable securities as of    , 2022. In addition, public stockholders who do not make the Election would be entitled to have their shares redeemed for cash if the Company has not completed an initial business combination by the expiration of the Extension Period if the Charter Amendment Proposal and the Trust Amendment Proposal are approved. Our initial stockholders, own an aggregate of 34,500,000 Founder Shares.

To exercise your redemption rights, you must tender your shares to the Company’s transfer agent at least two (2) business days prior to the Special Meeting (or    , 2022). You may tender your shares by either delivering your share certificate to the transfer agent or by delivering your shares electronically using the Depository Trust Company’s DWAC (Deposit/Withdrawal At Custodian) system. If you hold your shares in street name, you will need to instruct your bank, broker or other nominee to withdraw the shares from your account in order to exercise your redemption rights. The redemption rights include the requirement that a stockholder must identify itself in writing as a beneficial holder and provide its legal name, phone number and address in order to validly redeem its public shares.

As of    , 2022, there was approximately $    million in the trust account. If the Charter Amendment Proposal and the Trust Amendment Proposal are approved and the Company extends the business combination period to December 19, 2023 (or such earlier date as determined by our Board), the redemption price per share at the meeting for the initial business combination or the Company’s subsequent liquidation may be a different amount in comparison to the current redemption price of approximately $    per share under the terms of our currently existing charter and Trust Agreement.

The following discussion is a summary of certain United States federal income tax considerations for holders of our shares with respect to the exercise of redemption rights in connection with the approval of the Extension in connection with the Charter Amendment Proposal. This summary is based upon the Internal Revenue Code of 1986, as amended (the “Code”), the regulations promulgated by the U.S. Treasury Department, current administrative interpretations and practices of the Internal Revenue Service (the “IRS”), and judicial decisions, all as currently in effect and all of which are subject to differing interpretations or to change, possibly with retroactive effect. This summary does not discuss all aspects of United States federal income taxation that may be relevant to particular investors in light of their individual circumstances, such as investors subject to special tax rules including:

In addition, this summary does not discuss any state, local, or non-United States tax considerations, any non-income tax (such as gift or estate tax) considerations, alternative minimum tax or the Medicare tax. In addition, this summary is limited to investors that hold our shares as “capital assets” (generally, property held for investment) under the Code.

If a partnership (including an entity or arrangement treated as a partnership for United States federal income tax purposes) holds our shares, the tax treatment of a partner in such partnership will generally depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. If you are a partner of a partnership holding our shares, you are urged to consult your tax advisor regarding the tax consequences of a redemption.

We have not sought, and will not seek, a ruling from the IRS as to any United States federal income tax consequence described herein. The IRS may disagree with the tax consequences described herein, and no assurance can be given that the IRS would not assert, or that a court would not sustain a position contrary to any of the tax considerations described herein. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not adversely affect the accuracy of the statements in this discussion.

This section is addressed to U.S. Holders of our shares that elect to have their shares of the Company redeemed for cash pursuant to the Election (a “Redeeming U.S. Holder”). For purposes of this discussion, a “U.S. Holder” is a beneficial owner that so redeems its shares of the Company and is:

A U.S. Holder who does not make the Election (including any U.S. Holder who votes in favor of the Charter Amendment Proposal) will continue to own his shares and warrants, and will not recognize any income, gain or loss for U.S. federal income tax purposes by reason of the Charter Amendment Proposal.

A Redeeming U.S. Holder will generally be considered to have sold or exchanged its shares in a taxable transaction and recognize capital gain or loss equal to the difference between the amount realized on the redemption and such stockholder’s adjusted basis in the shares exchanged if the Redeeming U.S. Holder’s ownership of shares is completely terminated or if the redemption meets certain other tests described below. Special constructive ownership rules apply in determining whether a Redeeming U.S. Holder’s ownership of shares is treated as completely terminated (and in general, such Redeeming U.S. Holder may not be considered to have completely terminated its interest if it continues to hold our warrants). If gain or loss treatment applies, such gain or loss will be long-term capital gain or loss if the holding period of such shares is more than one year at the time of the exchange. It is possible that because of the redemption rights associated with our shares, the holding period of such shares may not be considered to begin until the date of such redemption (and thus it is possible that long-term capital gain or loss treatment may not apply to shares redeemed in the redemption). U.S. Holders who hold different blocks of shares (generally, shares purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

Cash received upon redemption that does not completely terminate the Redeeming U.S. Holder’s interest will still give rise to capital gain or loss, if the redemption is either (i) “substantially disproportionate” or (ii) “not essentially equivalent to a dividend.” In determining whether the redemption is substantially disproportionate or not essentially equivalent to a dividend with respect to a Redeeming U.S. Holder, that Redeeming U.S. Holder is deemed to own not just shares actually owned but also shares underlying rights to acquire our shares (including for these purposes our warrants) and, in some cases, shares owned by certain family members, certain estates and trusts of which the Redeeming U.S. Holder is a beneficiary, and certain affiliated entities.

Generally, the redemption will be “substantially disproportionate” with respect to the Redeeming U.S. Holder if (i) the Redeeming U.S. Holder’s percentage ownership of the outstanding voting shares (including all classes which carry voting rights) of the Company is reduced immediately after the redemption to less than 80% of the Redeeming U.S. Holder’s percentage interest in such shares immediately before the redemption; (ii) the Redeeming U.S. Holder’s percentage ownership of the outstanding shares (both voting and nonvoting) immediately after the redemption is reduced to less than 80% of such percentage ownership immediately before the redemption; and (iii) the Redeeming

U.S. Holder owns, immediately after the redemption, less than 50% of the total combined voting power of all classes of shares of the Company entitled to vote. Whether the redemption will be considered “not essentially equivalent to a dividend” with respect to a Redeeming U.S. Holder will depend upon the particular circumstances of that U.S. holder. At a minimum, however, the redemption must result in a meaningful reduction in the Redeeming U.S. Holder’s actual or constructive percentage ownership of the Company. The IRS has ruled that any reduction in a stockholder’s proportionate interest is a “meaningful reduction” if the stockholder’s relative interest in the corporation is minimal and the stockholder does not have meaningful control over the corporation.

If none of the redemption tests described above give rise to capital gain or loss, the consideration paid to the Redeeming U.S. Holder will be treated as distribution in respect of such shares for U.S. federal income (a “Distribution”). A Distribution will be treated as dividend income for U.S. federal income tax purposes to the extent of our current or accumulated earnings and profits. However, for purposes of the dividends-received deduction and of “qualified dividend” treatment, due to the redemption right, a Redeeming U.S. Holder may be unable to include the time period prior to the redemption in the stockholder’s “holding period.” Any Distribution in excess of our earnings and profits will reduce the Redeeming U.S. Holder’s basis in the shares (but not below zero), and any remaining excess will be treated as gain realized on the sale or other disposition of the shares.

As these rules are complex, U.S. holders of shares considering exercising their redemption rights should consult their own tax advisors as to whether the redemption will be treated as a sale or as a distribution under the Code.

Certain Redeeming U.S. Holders who are individuals, estates or trusts pay a 3.8% tax on all or a portion of their “net investment income” or “undistributed net investment income” (as applicable), which may include all or a portion of their capital gain or dividend income from their redemption of shares. Redeeming U.S. Holders should consult their tax advisors regarding the effect, if any, of the net investment income tax.

This section is addressed to Non-U.S. Holders of our shares that elect to have their shares of the Company redeemed for cash pursuant to the Election (“Redeeming Non-U.S. Holders”). For purposes of this discussion, a “Redeeming Non-U.S. Holder” is a beneficial owner (other than a partnership) that so redeems its shares of the Company and is not a U.S. Holder.

Any Redeeming Non-U.S. Holder will not be subject to U.S. federal income tax on any capital gain recognized as a result of the exchange unless:

Unless an applicable treaty provides otherwise, gain described in the second bullet point above will be subject to tax at generally applicable U.S. federal income tax rates as if the Redeeming Non-U.S. Holder were a U.S. Holder. Any gains described in the first bullet point above of a Redeeming Non-U.S. Holder that is a corporation for U.S. federal income tax purposes may also be subject to an additional “branch profits tax” at a rate of 30% (or a lower applicable treaty rate). If the second bullet point applies to a Redeeming Non-U.S. Holder, such Redeeming Non-U.S. Holder will be subject to U.S. tax on such Non-U.S. Holder’s net capital gain for such year (including any gain realized in connection with the redemption) at a rate of 30%. Note that a non-U.S. individual physically present in the U.S. for 183 days or more during a taxable year generally satisfies the substantial presence test, is taxable as a U.S. resident, and therefore is a U.S. Holder. If a non-U.S. individual has a special visa status, he or she may be a Non-U.S. Holder despite being physically present in the U.S. for 183 days or more.

If the third bullet point above applies to a Redeeming Non-U.S. Holder, gain recognized by such Redeeming Non-U.S. Holder on the deemed sale will be subject to tax at generally applicable U.S. federal income tax rates. In addition, the Company may be required to withhold U.S. federal income tax at a rate of 15% of the amount realized upon such disposition. The Company believes that it is not and has not been at any time since our formation a United States real property holding corporation.

If a redemption of a Redeeming Non-U.S. Holder’s shares is treated as a Distribution, as discussed above under the section entitled “—U.S. Federal Income Tax Treatment of Electing U.S. Holders” to the extent paid out of the Company’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles), such Distribution will constitute dividends for U.S. federal income tax purposes and, provided such dividends are not effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States, the Company will be required to withhold tax from the gross amount of the dividend at a rate of 30%, unless such Redeeming Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E). Any portion of a Distribution not constituting a dividend will be treated first as reducing (but not below zero) the Redeeming Non-U.S. Holder’s adjusted tax basis in its shares of Company stock and, to the extent such distribution exceeds the Redeeming Non-U.S. Holder’s adjusted tax basis, as gain realized from the sale or other disposition of the Company common stock, which will be treated as described in above.

Dividend payments with respect to our ordinary shares and proceeds from the sale, exchange or redemption of our ordinary shares may be subject to information reporting to the IRS and possible United States backup withholding. However, backup withholding will not apply to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status. A Non-U.S. Holder generally will eliminate the requirement for information reporting and backup withholding by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption. Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s United States federal income tax liability, and a holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

The Company will not pay any additional amounts to redeeming holders in respect of any amounts withheld in connection with a redemption of our shares. Under certain circumstances, a holder might be eligible for refunds or credits of such taxes.

As previously noted above, the foregoing discussion of certain U.S. federal income tax consequences is included for general information purposes only and is not intended to be, and should not be construed as, legal or tax advice to any stockholder. We once again urge you to consult with your own tax adviser to determine the particular tax consequences to you (including the application and effect of any U.S. federal, state, local or foreign income or other tax laws) of the receipt of cash in exchange for shares in connection with any redemption of your public shares.

The affirmative vote of holders of at least 65% of the outstanding shares of our common stock entitled to vote thereon is required to approve the Charter Amendment. Abstentions or the failure to vote on the Charter Amendment will have the same effect as a vote “AGAINST” the Charter Amendment.

Our Board will abandon and not implement the Charter Amendment Proposal unless our stockholders approve both the Charter Amendment Proposal and the Trust Amendment Proposal. This means that if one proposal is approved by the stockholders and the other proposal is not, neither proposal will take effect. Notwithstanding stockholder approval of the Charter Amendment and Trust Amendment, our Board will retain the right to abandon and not implement the Charter Amendment and Trust Amendment at any time before the effectiveness thereof without any further action by our stockholders.

You are not being asked to vote on any business combination at this time. If the Charter Amendment and Trust Amendment are implemented and you do not elect to redeem your public shares now, you will retain the

right to vote on the initial business combination if and when it is submitted to stockholders and the right to redeem your public shares for cash in the event a business combination is approved and completed or the Company has not consummated the business combination before the expiration of the Extension Period, subject to the terms of the charter.

OUR BOARD UNANIMOUSLY RECOMMENDS THAT OUR STOCKHOLDERS VOTE “FOR” THE CHARTER AMENDMENT.

Re:  Trust Account – Termination Letter

Pursuant to Section 1(i) of the Investment Management Trust Agreement between KKR Acquisition Holdings I Corp. (the “Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of March 19, 2021 (as amended, the “Trust Agreement”), this is to advise you that the Company did not effect a business combination with a Target Business (the “Business Combination”) within the time frame specified in the Company’s amended and restated certificate of incorporation (as amended, the “Charter”), as described in the Company’s Prospectus relating to the Offering. Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.

In accordance with the terms of the Trust Agreement, we hereby authorize you to liquidate all of the assets in the Trust Account and transfer the total proceeds into a segregated account held by you on behalf of the Beneficiaries to await distribution to the Public Stockholders. The Company has selected [      , 20 ]¹ as the effective date for the purpose of determining when the Public Stockholders will be entitled to receive their share of the liquidation proceeds. You agree to be the Paying Agent of record and, in your separate capacity as Paying Agent, agree to distribute said funds directly to the Company’s Public Stockholders in accordance with the terms of the Trust Agreement and the Company’s Charter. Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated, except to the extent otherwise provided in Section 1(i) of the Trust Agreement.
