(AFTER THE MERGERS DESCRIBED HEREIN)

The board of directors of Haymaker Acquisition Corp. 4, a Cayman Islands exempted company (“Haymaker” or the “SPAC”), has unanimously approved the Business Combination Agreement, dated as of October 9, 2025 (the “Business Combination Agreement”), by and among Haymaker, Suncrete, Inc., a Delaware corporation and direct wholly owned subsidiary of Haymaker (“New Suncrete” or “PubCo”), Haymaker Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of PubCo (“Merger Sub I”), Haymaker Merger Sub II, LLC, a Delaware limited liability company and direct wholly owned subsidiary of PubCo (“Merger Sub II” and together with Merger Sub I, the “Merger Subs”), and Concrete Partners Holding, LLC, a Delaware limited liability company (“Suncrete”), a copy of which is attached to this proxy statement/prospectus as Annex A.

Pursuant to the Business Combination Agreement, the business combination will be effected in three steps. Subject to the approval and adoption of the Business Combination Agreement by the shareholders of SPAC, on the date of the consummation of the Business Combination (the “Closing Date”): (a) SPAC will transfer by way of continuation out of its jurisdiction of incorporation from the Cayman Islands and domesticate into the State of Delaware (the “Domestication” and the time at which the Domestication becomes effective, the “Domestication Effective Time”); (b) immediately following the Domestication, Merger Sub I will merge with and into SPAC (the “Initial Merger”), with SPAC surviving the Initial Merger as a wholly owned subsidiary of PubCo (SPAC, in its capacity as the surviving corporation of the Initial Merger, is sometimes referred to herein as the “Surviving Corporation,” and the time at which the Initial Merger becomes effective, the “Initial Merger Effective Time”); and (c) immediately following the Initial Merger, Merger Sub II will merge with and into Suncrete (the “Acquisition Merger” and, together with the Initial Merger, the “Mergers”, and together with the Domestication and all other transactions contemplated by the Business Combination Agreement, the “Business Combination”), with Suncrete surviving the Acquisition Merger as a wholly owned subsidiary of New Suncrete.

In connection with the Domestication, SPAC will transfer by way of continuation out of its jurisdiction of incorporation from the Cayman Islands into the State of Delaware by (i) deregistering as a Cayman Islands exempted company with the Registrar of Companies of the Cayman Islands and (ii) continuing and domesticating as a Delaware corporation.

At the Domestication Effective Time, by virtue of the Domestication and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

(a)

each Class B Ordinary Share of SPAC, par value $0.0001 per share (“SPAC Class B Ordinary Share”), that is issued and outstanding immediately prior to the Domestication Effective Time will convert automatically, on a one-for-one basis, into a share of Class B Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class B Common Stock”);

​

(b)

each Class A Ordinary Share of SPAC, par value $0.0001 per share (“SPAC Class A Ordinary Share”), that is then-issued and outstanding will convert automatically, on a one-for-one basis, into a share of Class A Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class A Common Stock”);

​

(c)

each unit of the SPAC prior to the Domestication, each such unit comprised of one SPAC Class A Ordinary Share and one-half of one SPAC Cayman Warrant (as defined below) (a “SPAC Cayman Unit”) that is then issued and outstanding will convert automatically, on a one-for-one basis, into a unit of the SPAC following the Domestication, each such unit comprised of one share of SPAC Class A Common Stock and one-half of one SPAC Delaware Warrant (as defined below) (a “SPAC Delaware Unit”); and

​

(d)

each then issued and outstanding warrant to purchase SPAC Class A Ordinary Shares prior to the Domestication (a “SPAC Cayman Warrant”) will convert automatically, on a one-for-one basis, into one warrant to purchase SPAC Class A Common Stock (a “SPAC Delaware Warrant”), pursuant to and in accordance with that certain warrant agreement, dated July 25, 2023, between SPAC and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agreement”).

​

At the Initial Merger Effective Time, by virtue of the Initial Merger and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

(a)

each share of Common Stock of Merger Sub I, par value $0.0001 per share, issued and outstanding immediately prior to the Initial Merger Effective Time will be redeemed for par value;

​

(b)

each share of SPAC Class A Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time will be canceled and converted into one share of Class A Common Stock of PubCo, par value $0.0001 per share (“PubCo Class A Common Stock”);

​

(c)

each share of SPAC Class B Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time will be canceled and converted into one share of Class B Common Stock of PubCo, par value $0.0001 per share (“PubCo Class B Common Stock” and, together with the PubCo Class A Common Stock, the “PubCo Common Stock”);

​

(d)

each then-outstanding and unexercised SPAC Delaware Warrant will automatically be assumed and converted into a warrant to acquire one share of PubCo Class A Common Stock, subject to the same terms and conditions applicable to the corresponding former SPAC Cayman Warrant immediately prior to the Initial Merger Effective Time (each such resulting warrant, an “Assumed SPAC Warrant”); and

​

(e)

each SPAC Delaware Unit issued and outstanding immediately prior to the Initial Merger Effective Time will be detached into one share of PubCo Class A Common Stock and one-half of one Assumed SPAC Warrant.

​

Prior to the Acquisition Merger Effective Time, Concrete Management MEP, LLC (“Management Aggregator”) will distribute to its members, in redemption and cancellation of such members’ limited liability company interests in Management Aggregator, the Company Incentive Units, as defined in Suncrete’s existing Amended and Restated Limited Liability Company Agreement (as amended, the “Company LLC Agreement”), corresponding to such redeemed interests (the “Management Aggregator Distribution”).

At the Acquisition Merger Effective Time, by virtue of the Acquisition Merger and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

(a)

each Common Unit of Suncrete (each, a “Company Common Unit”) (other than any Company Incentive Units) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into the right to receive, in the aggregate, shares of PubCo Class B Common Stock and PubCo Class A Common Stock, as applicable, equal to the Company Common Unit Exchange Ratio (as defined in the Business Combination Agreement);

​

(b)

each Preferred Unit of Suncrete (each, a “Company Preferred Unit”) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into the right to receive shares of PubCo Class B Common Stock and PubCo Class A Common Stock, as applicable, equal to Company Preferred Unit Exchange Ratio (as defined in the Business Combination Agreement);

​

(c)

each Senior Preferred Unit of Suncrete (“Company Senior Preferred Unit”) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into the right to receive a cash payment in the amount equal to the Unreturned Senior Preferred Contribution (as defined in the Company LLC Agreement) with respect to such Company Senior Preferred Unit, calculated in accordance with the terms set forth in the Company LLC Agreement;

​

(d)

each Company Incentive Unit issued and outstanding immediately prior to the Acquisition Merger Effective Time will be automatically cancelled and converted into the right to receive a number of restricted shares of PubCo Class A Common Stock equal to the Company Incentive Unit Share Consideration (as defined in the Business Combination Agreement) with respect to such Company Incentive Unit (each, a “Rollover Equity Award”); provided, that each holder of a Rollover Equity Award will enter into a side letter agreement at the Acquisition Merger Effective Time pursuant to which each such holder will agree that their Rollover Equity Award will be subject to the same terms and conditions (including applicable vesting, expiration and forfeiture provisions) that applied to such Company Incentive Unit immediately prior to the Acquisition Merger Effective Time;

​

(e)

each Company Unit held in treasury of Suncrete as of immediately prior to the Acquisition Merger Effective Time will thereupon be cancelled without any conversion thereof and no payment or distribution will be made within respect thereto;

​

(f)

each share of PubCo Class B Common Stock issued and outstanding immediately prior to the Acquisition Merger Effective Time will be converted into and exchanged, on a one-for-one basis, into one share of PubCo Class A Common Stock (subject to clause (h) below);

​

(g)

each Unit of Merger Sub II issued and outstanding immediately prior to the Acquisition Merger Effective Time will be converted into and exchanged for one validly issued, fully paid and non-assessable unit of Suncrete;

​

(h)

upon distribution by Haymaker Sponsor IV, LLC (the “Sponsor”) of the Dothan Founder Shares (as defined below) (together with the Dothan Assumed Warrants (as defined below), such distribution, the “Sponsor Distribution”) to Dothan Independent GP, LP, an affiliate of Suncrete (“Dothan Independent”), each Dothan Founder Share will be converted into and exchanged, on a one-for-one basis, into one share of PubCo Class B Common Stock; and

​

(i)

subject to the receipt by Suncrete prior to the Acquisition Merger Effective Time of the necessary waivers, approvals, consents or authorizations and the satisfaction of certain contractual requirements, PubCo will issue 2,500,000 shares of PubCo Class B Common Stock to Dothan Independent.

​

In addition, immediately prior to the Domestication Effective Time, SPAC will redeem all of the issued and outstanding SPAC Public Warrants at $[•] per SPAC Public Warrant (the “Warrant Redemption”), which redemption will be effected by SPAC by way of an amendment to the Warrant Agreement if the proposal to effectuate such amendment is approved by the requisite holders of the then-outstanding SPAC Cayman Warrants (“SPAC Warrantholders”).

This proxy statement/prospectus covers 76,106,799 shares of PubCo Class A Common Stock, 26,793,525 shares of Class B Common Stock and up to 11,898,800 Assumed SPAC Warrants. The number of shares of PubCo Class A Common Stock and PubCo Class B Common Stock that this proxy statement/prospectus covers represents the maximum number of shares that may be issued to holders of Suncrete equity interests in connection with the Acquisition Merger (as more fully described in this proxy statement/prospectus), together with the shares issued or issuable to the existing holders of SPAC Class A Ordinary Shares, SPAC Class B Ordinary Shares, SPAC Cayman Warrants, and SPAC Units in connection with the Domestication and the Initial Merger, shares issuable upon exercise of the Assumed SPAC Warrants and shares issuable upon the conversion of PubCo Class B Common Stock.

The SPAC Units, SPAC Class A Ordinary Shares and SPAC Public Warrants are currently listed on the NYSE under the symbols “HYAC.U”, “HYAC” and “HYAC.WS”, respectively. The parties anticipate that, following the Business Combination, the PubCo Class A Common Stock and Assumed SPAC Warrants will be listed on the NYSE and the NYSE Texas under the symbols “RMIX” and “RMIX.W”, respectively, and the SPAC Units, SPAC Class A Ordinary Shares, and SPAC Public Warrants will cease trading on the NYSE and will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) upon the consummation of the Initial Merger.

After the completion of the Business Combination, PubCo will be a “controlled company” within the meaning of the NYSE’s listing standards. PubCo will qualify for exemptions from certain corporate governance listing standards of the NYSE and intends to avail itself of such exemptions, in whole or in part, for so long as the SunTx Group (as defined below) continues to hold a majority of the outstanding shares of PubCo’s outstanding common stock. We anticipate that the SunTx Group will beneficially own approximately 81.9% of the voting power of outstanding PubCo Common Stock following the completion of the Business Combination, assuming no redemption rights in connection with the Business Combination are exercised.

Material Financings

Concurrently with the execution of the Business Combination Agreement, Haymaker, PubCo and certain institutional investors (collectively, the “PIPE Investors”) entered into Subscription Agreements (the “PIPE Subscription Agreements”) pursuant to which, among other things, PubCo agreed to issue and sell to the PIPE Investors, in a private placement to close immediately prior to the Acquisition Merger Effective Time, an aggregate of approximately $82.5 million in shares of PubCo Class A Common Stock (or pre-funded warrants in lieu thereof) (the “PIPE Offering”).

On September 10, 2025, Dothan Independent and the Sponsor entered into a subscription agreement and amendment to LLC agreement (the “Sponsor Subscription Agreement”), pursuant to which Dothan Independent agreed to contribute $500,000 in cash to Sponsor in exchange for 10 Class Z Units of Sponsor (representing an indirect interest in 2,800,000 SPAC Founder Shares (the “Dothan Founder Shares”) and an indirect interest in the Sponsor’s 398,800 private placement warrants (the “Dothan Assumed Warrants”)) in order to loan and fund certain extension costs to the SPAC. At the Acquisition Merger Effective Time, pursuant to the Sponsor Distribution, Sponsor will distribute the Dothan Founder Shares and the Dothan Assumed Warrants to Dothan Independent, and following the Business Combination, as a result of its investment in Sponsor, Dothan Independent will receive 2,800,000 shares of PubCo Class B Common Stock and 398,800 Assumed SPAC Warrants.

Compensation Received by the Sponsor and its Affiliates

Set forth below is a summary of the terms and amount of the compensation received or to be received by the Sponsor and its affiliates in connection with the Business Combination or any related financing transaction, the amount of securities issued or to be issued by PubCo to the Sponsor and its affiliates and the price paid or to be paid for such securities or any related financing transaction. See the subsection titled “The Business Combination — Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination” for additional information.

Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination

In considering the recommendation of the SPAC Board to vote in favor of the Business Combination, shareholders should be aware that, aside from their interests as shareholders, the Sponsor and certain of SPAC’s directors and officers have interests in the Business Combination that are different from, or in addition to, those of other shareholders generally. SPAC’s directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to shareholders that they approve the Business Combination. Shareholders should take these interests into account in deciding whether to approve the Business Combination. These interests include, among other things:

​

•

the fact that the Sponsor holds 797,600 private placement units, consisting of 398,800 private placement warrants (provided, that such warrants will be conveyed to Dothan Independent in the Sponsor Distribution, as provided in the Sponsor Subscription Agreement) and 797,600 private placement shares, acquired at an aggregate purchase price of $7,976,000, which, if unrestricted and freely tradeable, would be valued at approximately $9,418,856, based on the most recent closing prices of the SPAC Public Warrants and the SPAC Class A Ordinary Shares on November 7, 2025 of $1.00 per warrant and $11.31 per share, respectively (prior to giving effect to the Sponsor Distribution);

​

•

the fact that the Sponsor and SPAC’s officers and directors have agreed to not redeem any SPAC Class A Ordinary Shares held by them in connection with a shareholder vote to approve the Business Combination;

​

•

the fact that the Sponsor paid an aggregate of $25,000 for 5,750,000 SPAC Founder Shares (provided, that 2,800,000 SPAC Founder Shares will be conveyed to Dothan Independent in the Sponsor Distribution, as provided in the Sponsor Subscription Agreement), and that such SPAC Founder Shares could have a significantly higher value at the time of the Business Combination, which if unrestricted and freely tradable would be valued at approximately $65,032,500, based on the most recent closing price of the SPAC Class A Ordinary Shares of $11.31 per share on November 7, 2025 (prior to giving effect to the Sponsor Distribution);

​

•

if the Trust Account is liquidated, including in the event SPAC is unable to consummate an Initial Business Combination within the completion window set forth in the Existing Organizational Documents, the Sponsor has agreed to indemnify SPAC to ensure that the proceeds in the Trust Account are not reduced below $10.00 per Public Share, or such lesser amount per Public Share as is in the Trust Account on the liquidation date, by the claims of (a) any third party (other than SPAC’s independent registered public accounting firm) for services rendered or products sold to SPAC or (b) a prospective target business with which SPAC has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement, but only if such a third party or target business has not executed a waiver of all rights to seek access to the Trust Account;

​

•

the fact that the Sponsor and SPAC’s officers, directors and advisors will be reimbursed for out-of-pocket expenses incurred in connection with activities on SPAC’s behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations;

​

•

the fact that the Sponsor and SPAC’s officers, directors and advisors will lose their entire investment in SPAC if an Initial Business Combination is not completed within the period ending on July 28, 2026, subject to monthly extensions as described elsewhere in this proxy statement/prospectus and in the Existing Organizational Documents (the “Combination Period”);

​

•

the fact that the Sponsor has invested an aggregate of $8,001,000 (consisting of $25,000 for the SPAC Founder Shares and $7,976,000 for the private placement units), which means that the Sponsor and Haymaker’s officers and directors stand to make a significant profit on their investment and could potentially recoup their entire investment in Haymaker even if the trading price of the PubCo Class A Common Stock was as low as approximately $[•] per share (after giving effect to the transfer to Dothan Independent of the Dothan Founder Shares and Dothan Assumed Warrants following the Sponsor Distribution and assuming the loans and out-of-pocket expenses described below are repaid and reimbursed, respectively, by Haymaker). Therefore, the Sponsor and Haymaker’s directors and officers may experience a positive rate of return on their investment, even if our Public Shareholders experience a negative rate of return on their investment;

​

​

•

the fact that after the Business Combination, assuming there are no redemptions of Public Shares in connection with the Business Combination, the Sponsor will beneficially own approximately 1.2% of the PubCo Class A Common Stock. Please see the section titled “Summary of the Proxy Statement/​Prospectus — Ownership of New Suncrete After the Closing” for additional information;

​

•

the fact that the Sponsor and Haymaker’s directors and officers may be incentivized to complete the Business Combination, or an alternative initial business combination, with a less favorable company or on terms less favorable to shareholders, rather than to liquidate, which would cause the Sponsor to lose its entire investment. As a result, the Sponsor may have a conflict of interest in determining whether Suncrete is an appropriate business with which to complete a business combination and/or in evaluating the terms of the Business Combination;

​

•

the fact that the Sponsor and Haymaker’s officers and directors (or their affiliates) have made, and may make in the future, working capital and extension loans to Haymaker. As of September 30, 2025, the Sponsor has loaned an aggregate of approximately $1,880,000 to Haymaker under unsecured promissory notes to fund operating and transaction expenses in connection with the Business Combination and fund payments into the Trust Account, in accordance with the Existing Organizational Documents, to extend the date by which Haymaker must consummate an initial business combination, and may make additional loans after the date of this proxy statement/​prospectus for such purposes. If the Business Combination is not consummated and another business combination is not otherwise completed, these working capital loans may not be repaid and would be forgiven except to the extent there are funds available to Haymaker outside of the Trust Account;

​

​

•

the fact that pursuant to the Existing Organizational Documents, Haymaker has renounced any interest or expectancy of Haymaker in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for both Haymaker and any individual serving as a director or officer of Haymaker, about which any such director or officer acquires knowledge. In the course of their other business activities, Haymaker’s officers and directors may have become aware of other investment and business opportunities which might have been appropriate for presentation to Haymaker as well as the other entities with which they were affiliated. Haymaker’s management had pre-existing fiduciary duties and contractual obligations and if there was a conflict of interest in determining to which entity a particular business opportunity should be presented, any entity with whom Haymaker’s management had a pre-existing fiduciary obligation would have been presented the opportunity before Haymaker was presented with it (see the subsection titled “Fiduciary Duties of Haymaker’s Directors and Officers” for more information). Haymaker does not believe, however, that the fiduciary duties or contractual obligations of Haymaker’s officers or directors materially affected Haymaker’s search for a business combination, including the negotiation or recommendation thereof or the provision of advice in connection therewith;

​

•

the fact that the Sponsor transferred an indirect interest in a portion of its SPAC Founder Shares and all of its private placement warrants to Dothan Independent;

​

•

the anticipated service of Andrew Heyer and Christopher Bradley as directors of New Suncrete following the Business Combination, and the compensation that they will receive for such service; and

​

•

the fact that Haymaker’s existing directors and officers will be entitled to indemnification and the continuation of Haymaker’s directors’ and officers’ liability insurance after the Business Combination.

​

See the subsection titled “The Business Combination — Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination” for additional information.

After careful consideration, the board of directors of Haymaker has unanimously approved the Business Combination Agreement and related transactions and the board of directors of Haymaker has approved the other proposals described in the accompanying proxy statement/prospectus, determined that it is advisable to consummate the Business Combination, and further determined that the Business Combination is in the best interests of the SPAC and its securityholders. This proxy statement/prospectus provides shareholders and warrantholders of Haymaker with detailed information about the Business Combination and other matters to be considered at the extraordinary general meeting of Haymaker’s shareholders and the special meeting of Haymaker’s warrantholders. We encourage you to read this entire document, including the annexes and other documents referred to herein, carefully and in their entirety. You should also carefully consider the risk factors described in the section titled “Risk Factors” beginning on page 48 of this proxy statement/prospectus.

NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES REGULATORY AGENCY HAS APPROVED OR DISAPPROVED OF THE TRANSACTIONS DESCRIBED IN THIS PROXY STATEMENT/PROSPECTUS, PASSED UPON THE MERITS OR FAIRNESS OF THE BUSINESS COMBINATION OR RELATED TRANSACTIONS, OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS PROXY STATEMENT/​PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.

This proxy statement/prospectus is dated [•], 2026, and
is first being mailed to Haymaker’s shareholders and warrantholders on or about [•], 2026.

 

HAYMAKER ACQUISITION CORP. 4

324 Royal Palm Way, Suite 300-I
Palm Beach, Florida 33480

Dear Haymaker Acquisition Corp. 4 Shareholders and Warrantholders:

You are cordially invited to attend the extraordinary general meeting of shareholders (the “Shareholders’ Meeting”) of Haymaker Acquisition Corp. 4, a Cayman Islands exempted company (“Haymaker,” “SPAC,” “our,” or “us”), which will be held at the offices of DLA Piper LLP (US) at 1251 Avenue of the Americas, New York, New York 10020, on [•], 2026, at [•] Eastern Time, or such other date, time, and place to which such meeting may be adjourned, and/or the meeting of warrantholders (the “Warrantholders’ Meeting” and together with the Shareholders’ Meeting, the “Meetings”) of Haymaker, which will be held at the offices of DLA Piper LLP (US) at 1251 Avenue of the Americas, New York, New York 10020, on [•], 2026, at [•] Eastern Time, or such other date, time, and place to which such meeting may be adjourned. We are also planning for both meetings to be held virtually pursuant to the procedures described in the accompanying proxy statement/prospectus, but the physical location of the Meetings will remain at the location specified above for purposes of The Companies Act (Revised) of the Cayman Islands and our Amended and Restated Memorandum and Articles of Association (the “Existing Organizational Documents”).

At the Shareholders’ Meeting, Haymaker will ask its shareholders to consider and vote upon two separate proposals (the “Initial Merger Proposal” and the “Acquisition Merger Proposal,” collectively the “Business Combination Proposals”) to approve the Business Combination and to approve and adopt the Business Combination Agreement, dated as of October 9, 2025 (the “Business Combination Agreement”), by and among Haymaker, Suncrete, Inc., a Delaware corporation and direct wholly owned subsidiary of Haymaker (“New Suncrete” or “PubCo”), Haymaker Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of PubCo (“Merger Sub I”), Haymaker Merger Sub II, LLC, a Delaware limited liability company and direct wholly owned subsidiary of PubCo (“Merger Sub II” and together with Merger Sub I, the “Merger Subs”), and Concrete Partners Holding, LLC, a Delaware limited liability company (“Suncrete”), which provides for a business combination between Haymaker and Suncrete.

Pursuant to the Business Combination Agreement, the business combination will be effected in three steps. Subject to the approval and adoption of the Business Combination Agreement by ordinary resolution of the shareholders of SPAC, on the date of the consummation of the Business Combination (the “Closing Date”): (a) SPAC will transfer by way of continuation out of its jurisdiction of incorporation from the Cayman Islands to the State of Delaware (the “Domestication” and the time at which the Domestication becomes effective, the “Domestication Effective Time”), (b) immediately following the Domestication, Merger Sub I will merge with and into SPAC (the “Initial Merger”), with SPAC surviving the Initial Merger as a wholly owned subsidiary of PubCo (SPAC, in its capacity as the surviving corporation of the Initial Merger, is sometimes referred to herein as the “Surviving Corporation,” and the time at which the Initial Merger becomes effective, the “Initial Merger Effective Time”); and (c) immediately following the Initial Merger, Merger Sub II will merge with and into Suncrete (the “Acquisition Merger” and, together with the Initial Merger, the “Mergers”, and together with the Domestication and all other transactions contemplated by the Business Combination Agreement, the “Business Combination”), with Suncrete surviving the Acquisition Merger as a wholly owned subsidiary of New Suncrete.

In connection with the Domestication, SPAC will transfer by way of continuation out of its jurisdiction of incorporation from the Cayman Islands to the State of Delaware by (i) deregistering as a Cayman Islands exempted company with the Registrar of Companies of the Cayman Islands and (ii) continuing and domesticating as a Delaware corporation.

At the Domestication Effective Time, by virtue of the Domestication and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

(a)

each Class B Ordinary Share of SPAC, par value $0.0001 per share (“SPAC Class B Ordinary Share”), that is issued and outstanding immediately prior to the Domestication Effective Time will convert automatically, on a one-for-one basis, into a share of Class B Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class B Common Stock”);

​

 

 

(b)

each Class A Ordinary Share of SPAC, par value $0.0001 per share (“SPAC Class A Ordinary Share”), that is then-issued and outstanding will convert automatically, on a one-for-one basis, into a share of Class A Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class A Common Stock”);

​

(c)

each unit of the SPAC prior to the Domestication, each such unit comprised of one SPAC Class A Ordinary Share and one-half of one SPAC Cayman Warrant (as defined below) (a “SPAC Cayman Unit”) that is then issued and outstanding will convert automatically, on a one-for-one basis, into a unit of the SPAC following the Domestication, each such unit comprised of one share of SPAC Class A Common Stock and one-half of one SPAC Delaware Warrant (as defined below) (a “SPAC Delaware Unit”); and

​

(d)

each then issued and outstanding warrant to purchase SPAC Class A Ordinary Shares prior to the Domestication (a “SPAC Cayman Warrant”) will convert automatically, on a one-for-one basis, into one warrant to purchase SPAC Class A Common Stock (a “SPAC Delaware Warrant”), pursuant to and in accordance with the Warrant Agreement.

​

At the Initial Merger Effective Time, by virtue of the Initial Merger and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

​

(e)

each SPAC Delaware Unit issued and outstanding immediately prior to the Initial Merger Effective Time will be detached into one share of PubCo Class A Common Stock and one-half of one Assumed SPAC Warrant.

​

Prior to the Acquisition Merger Effective Time, Concrete Management MEP, LLC (“Management Aggregator”) will distribute to its members, in redemption and cancellation of such members’ limited liability company interests in Management Aggregator, the Company Incentive Units, as defined in Suncrete’s existing Amended and Restated Limited Liability Company Agreement (as amended, the “Company LLC Agreement”), corresponding to such redeemed interests (the “Management Aggregator Distribution”).

At the Acquisition Merger Effective Time, by virtue of the Acquisition Merger and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

(a)

each Common Unit of Suncrete (each, a “Company Common Unit”) (other than any Company Incentive Units) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into the right to receive, in the aggregate, shares of PubCo Class B Common Stock and PubCo Class A Common Stock, as applicable, equal to the Company Common Unit Exchange Ratio (as defined in the Business Combination Agreement);

​

(b)

each Preferred Unit of Suncrete (each, a “Company Preferred Unit”) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into

(c)

each Senior Preferred Unit of Suncrete (“Company Senior Preferred Unit”) issued and outstanding immediately prior to the Acquisition Merger Effective Time will be canceled and converted into the right to receive a cash payment in the amount equal to the Unreturned Senior Preferred Contribution (as defined in the Company LLC Agreement) with respect to such Company Senior Preferred Unit, calculated in accordance with the terms set forth in the Company LLC Agreement;

​

(d)

each Company Incentive Unit issued and outstanding immediately prior to the Acquisition Merger Effective Time will be automatically cancelled and converted into the right to receive a number of restricted shares of PubCo Class A Common Stock equal to the Company Incentive Unit Share Consideration (as defined in the Business Combination Agreement) with respect to such Company Incentive Unit (each, a “Rollover Equity Award”); provided, that each holder of a Rollover Equity Award will enter into a side letter agreement at the Acquisition Merger Effective Time pursuant to which each such holder will agree that their Rollover Equity Award will be subject to the same terms and conditions (including applicable vesting, expiration and forfeiture provisions) that applied to such Company Incentive Unit immediately prior to the Acquisition Merger Effective Time;

​

(e)

each Company Unit held in treasury of Suncrete as of immediately prior to the Acquisition Merger Effective Time will thereupon be cancelled without any conversion thereof and no payment or distribution will be made within respect thereto;

​

(f)

each share of PubCo Class B Common Stock issued and outstanding immediately prior to the Acquisition Merger Effective Time will be converted into and exchanged, on a one-for-one basis, into one share of PubCo Class A Common Stock (subject to clause (h) below);

​

​

(i)

subject to the receipt by Suncrete prior to the Acquisition Merger Effective Time of the necessary waivers, approvals, consents or authorizations and the satisfaction of certain contractual requirements, PubCo will issue 2,500,000 shares of PubCo Class B Common Stock to Dothan Independent.

​

In addition, immediately prior to the Domestication Effective Time, SPAC will redeem all of the issued and outstanding SPAC Public Warrants at $[•] per SPAC Public Warrant (the “Warrant Redemption”), which redemption will be effected by SPAC by way of an amendment (the “Warrant Amendment”) to that certain Warrant Agreement, dated July 25, 2023, between SPAC and Continental Stock Transfer & Trust Company, as warrant agent (the “Warrant Agreement”) if the proposal to effectuate such amendment is approved by holders of a majority of the number of the then outstanding SPAC Cayman Warrants (“SPAC Warrantholders”).

Concurrently with the execution of the Business Combination Agreement, Haymaker, PubCo and certain institutional investors (collectively, the “PIPE Investors”) entered into Subscription Agreements (the “PIPE Subscription Agreements”) pursuant to which, among other things, PubCo agreed to issue and sell to the PIPE Investors, in a private placement to close immediately prior to the Acquisition Merger Effective Time, an aggregate of approximately $82.5 million in shares of PubCo Class A Common Stock (or pre-funded warrants in lieu thereof) (the “PIPE Offering”).

 

 

In addition to the Business Combination Proposals, Haymaker’s shareholders will also be asked to consider and vote upon (a) a proposal to approve, on a non-binding advisory basis, by ordinary resolution, the change of SPAC’s jurisdiction of incorporation by deregistering as an exempted company with the Registrar of Companies of the Cayman Islands and continuing and domesticating as a corporation incorporated under the laws of the State of Delaware (the “Domestication Proposal”), (b) a proposal to approve by special resolution the adoption of the proposed certificate of incorporation (the “Proposed SPAC Certificate of Incorporation”) and the proposed bylaws (the “Proposed SPAC Bylaws”) of SPAC to be in effect following the Domestication (the “SPAC Organizational Documents Proposal”), and the adoption of the proposed amended and restated certificate of incorporation (the “Proposed PubCo Certificate of Incorporation”) and the proposed amended and restated bylaws (the “Proposed PubCo Bylaws”) of PubCo to be in effect at the Initial Merger Effective Time (the “PubCo Organizational Documents Proposal” and together with the SPAC Organizational Documents Proposal, the “Organizational Documents Proposal”); (c) eight separate proposals to approve, on a non-binding advisory basis, by ordinary resolution, material differences between the Existing Organizational Documents and the Proposed SPAC Certificate of Incorporation, the Proposed SPAC Bylaws and the Proposed PubCo Certificate of Incorporation and the Proposed PubCo Bylaws (collectively, the “Advisory Organizational Documents Proposals”); (d) a proposal to approve by ordinary resolution, for purposes of complying with the applicable listing rules of The New York Stock Exchange, the issuance of up to an aggregate of 40,782,500 shares of PubCo Class A Common Stock in connection with the Business Combination and the PIPE Offering (the “NYSE Proposal”); (e) a proposal to approve by ordinary resolution and adopt the Suncrete, Inc. 2026 Omnibus Incentive Plan and material terms thereunder, a copy of which is attached to the accompanying proxy statement/prospectus as Annex G (the “2026 Plan Proposal”); (f) a proposal to approve by ordinary resolution and adopt the Suncrete, Inc. Employee Stock Purchase Plan and material terms thereunder, a copy of which is attached to the accompanying proxy statement/prospectus as Annex H (the “ESPP Proposal”); and (g) a proposal to approve by ordinary resolution the adjournment of the Shareholders’ Meeting to a later date or dates, if necessary or convenient, (h) to permit further solicitation and vote of proxies in the event that there are insufficient votes for, or otherwise in connection with the approval of one or more proposals at the Shareholders’ Meeting, (ii) if Haymaker determines that one or more of the conditions to Closing is not or will not be satisfied or waived or (iii) to facilitate the Domestication, the Mergers or any other transaction contemplated by the Business Combination Agreement or the related agreements (the “Adjournment Proposal” and, together with the Business Combination Proposals, the Domestication Proposal, the Organizational Documents Proposal, the Advisory Organizational Documents Proposals, the NYSE Proposal, the 2026 Plan Proposal, and the ESPP Proposal, the “Proposals”).

We may not consummate the Business Combination unless the Business Combination Proposals, the Domestication Proposal, the Organizational Documents Proposal, the NYSE Proposal, the 2026 Plan Proposal and the ESPP Proposal (collectively, the “Condition Precedent Proposals”) are approved at the Shareholders’ Meeting. Each of the Condition Precedent Proposals is cross-conditioned on the approval of each of the other Condition Precedent Proposals. The Advisory Organizational Documents Proposals and the Adjournment Proposal are not conditioned on the approval of any other Proposal set forth in the accompanying proxy statement/prospectus. The approval of each of the Initial Merger Proposal, the Acquisition Merger Proposal, the Domestication Proposal, the Advisory Organizational Documents Proposals, the NYSE Proposal, the 2026 Plan Proposal, the ESPP Proposal, and the Adjournment Proposal are being proposed as an ordinary resolution, requiring the affirmative vote (in person or by proxy) of the holders of a simple majority of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Approval of the Organizational Documents Proposals requires a special resolution under The Companies Act (Revised) of the Cayman Islands, requiring the affirmative vote of the holders of at least two-thirds of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Accordingly, a shareholder’s failure to vote in person, online, or by proxy at the Shareholders’ Meeting will have no effect on the outcome of the vote on any of the Proposals, assuming a valid quorum is established. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Shareholders’ Meeting.

In connection with the Business Combination, certain related agreements have been, or will be, entered into on or prior to the consummation of the Business Combination, including: (a) the Company Equityholder

 

 

Support Agreement, dated as of October 9, 2025, pursuant to which certain equityholders of Suncrete have agreed to, among other things, (y) vote in favor of the approval and adoption of the transactions contemplated by the Business Combination Agreement and (z) certain lock-up restrictions with respect to their Suncrete securities, as well as any securities of PubCo issued to such holders pursuant to the Business Combination Agreement, in each case subject to certain exceptions; (b) the Lock-Up Agreement, dated as of October 9, 2025 (the “Parent Lock-Up Agreement”), by Dothan Concrete Investors, LLC (“Dothan Concrete” or “Parent”), pursuant to which Dothan Concrete agreed to, among other things, certain lock-up restrictions with respect to its Suncrete securities, as well as any securities of PubCo issued to Dothan Concrete pursuant to the Business Combination Agreement, (c) the Sponsor Support Agreement, dated as of October 9, 2025, pursuant to which Haymaker Sponsor IV LLC (the “Sponsor”) and certain of SPAC’s directors and officers (together with the Sponsor, the “Sponsor Related Parties”) have agreed to, among other things, (w) vote in favor of the approval and adoption of the transactions contemplated by the Business Combination Agreement, (x) waive the anti-dilution rights set forth in the Existing Organizational Documents, (y) certain lock-up restrictions with respect to their SPAC securities, as well as any securities of PubCo issued to the Sponsor Related Parties pursuant to the Business Combination Agreement, in each case subject to certain exceptions set forth in the Sponsor Support Agreement, and (z) in the case of the Sponsor, immediately upon the occurrence of the Initial Merger Effective Time, automatically be deemed to have irrevocably transferred to PubCo, surrendered and forfeited for no consideration a number of shares of PubCo Class A Common Stock equal to up to 333,333 shares of PubCo Class A Common Stock, (d) the Assignment, Assumption, and Amendment Agreement (the “RRA Assignment”) with respect to that certain Registration Rights Agreement, dated as of July 25, 2023, by and among SPAC, Sponsor and certain other SPAC equityholders, which shall, for the avoidance of doubt, terminate any underwritten demand and piggyback registration rights thereunder (but retain the right to demand a resale shelf registration on Form S-1 or, if available, Form S-3), (e) the Registration Rights Agreement, which will be entered into concurrently with the Acquisition Merger Effective Time by and among PubCo, Dothan Independent and certain members of Suncrete, (f) the Subscription Agreement, effective as of September 10, 2025 (the “Sponsor Subscription Agreement”), pursuant to which, among other things, Dothan Independent became a member of the Sponsor and agreed to contribute $500,000 in the aggregate to the Sponsor in exchange for 10 Class Z Units of the Sponsor, representing an indirect interest in 2,800,000 SPAC Founder Shares (the “Dothan Founder Shares”) and an indirect interest in all of the private placement warrants (the “Dothan Founder Warrants”), and (g) the Amendment No. 1 to the Management and Consulting Agreement, which, subject to the receipt by Suncrete prior to the Acquisition Merger Effective Time of the necessary waivers, approvals, consents or authorizations set forth in the Business Combination Agreement, will be entered into by and among Suncrete, PubCo and Dothan Concrete Investments Management, LLC, an affiliate of Suncrete (“Dothan Management”), effective as of Acquisition Merger Effective Time, pursuant to which, among other things, PubCo will assume, and agree to perform and discharge, all of the obligations of Suncrete under the Management and Consulting Agreement, dated as of July 29, 2024, by and between Suncrete and Dothan Management.

Pursuant to the Existing Organizational Documents, a holder of SPAC Class A Ordinary Shares issued as part of the Haymaker Units in the initial public offering (the “Public Shares,” and holders of such Public Shares, the “Public Shareholders”), other than the holders of the SPAC Founder Shares, which includes the Sponsor and SPAC’s independent directors (but for the avoidance of doubt, not including the holders of the Dothan Founder Shares following the Sponsor Distribution) (such holders of SPAC Founder Shares, the “Initial Shareholders”), may request that Haymaker redeem all or a portion of such Public Shares for cash if the Business Combination is consummated. Holders of Haymaker Units must elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Warrants prior to exercising redemption rights with respect to the Public Shares. If Public Shareholders hold their Haymaker Units in an account at a brokerage firm or bank, such Public Shareholders must notify their broker or bank that they elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and warrants, or if a holder holds Haymaker Units registered in its own name, the holder must contact Continental Stock Transfer and Trust Company (“Continental”), Haymaker’s transfer agent, directly and instruct it to do so. The redemption rights include the requirement that a holder must identify itself to Haymaker in order to validly redeem its shares. Public Shareholders (other than the Initial Shareholders) may elect to exercise their redemption rights with respect to their Public Shares regardless of whether they vote “FOR” or “AGAINST” the Business Combination Proposals. If the Business Combination is not consummated, the Public Shares

 

 

will be returned to the respective holder, broker, or bank. If the Business Combination is consummated, and if a Public Shareholder properly exercises its redemption right with respect to all or a portion of the Public Shares that it holds and timely delivers its shares to Continental, Haymaker will redeem such Public Shares for a per-share price, payable in cash, equal to the pro-rata portion of the trust account established at the consummation of Haymaker’s initial public offering, calculated as of two business days prior to the consummation of the Business Combination. For illustrative purposes, as of the record date, this would have amounted to approximately $[•] per issued and outstanding Public Share. If a Public Shareholder exercises its redemption rights in full, then it will not own Public Shares or shares of PubCo Class A Common Stock following the Business Combination. The redemption will take place prior to the Domestication Effective Time. See the subsection titled “Extraordinary General Meeting of Shareholders and Special Meeting of Warrantholders — Redemption Rights” in the accompanying proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to exercise your rights with respect to your Public Shares.

Notwithstanding the foregoing, a Public Shareholder, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its Public Shares with respect to more than an aggregate of 15% of the Public Shares. Accordingly, if a Public Shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the Public Shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

The Sponsor and certain of Haymaker’s officers and directors have agreed to (a) vote all of their SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares in favor of the Business Combination and (b) waive their redemption rights with respect to their SPAC Class B Ordinary Shares and any Public Shares they own in connection with the consummation of the Business Combination. Such SPAC Class B Ordinary Shares will be excluded from the pro rata calculation used to determine the per-share redemption price applicable to Public Shares that are redeemed. As of the date of the accompanying proxy statement/prospectus, the Initial Shareholders own approximately 22.2% of the issued and outstanding SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares in the aggregate.

At the Warrantholders’ Meeting, holders of SPAC Cayman Warrants will be asked to consider and vote on (a) a proposal to approve an amendment to the terms of the Warrant Agreement in the form attached to the accompanying proxy statement/prospectus as Annex I thereto to provide that, immediately prior to the Domestication Effective Time, each SPAC Public Warrant, which entitles the holder thereof to purchase one SPAC Class A Ordinary Share, will be redeemed by SPAC in exchange for a cash payment of $[•] per SPAC Public Warrant (the “Warrant Amendment Proposal”) and (b) a proposal to allow Haymaker’s board of directors to adjourn the Warrantholders’ Meeting to a later date or dates to permit further solicitation of proxies (the “Warrantholder Adjournment Proposal”).

The Business Combination Agreement is subject to the satisfaction or waiver of certain other closing conditions as described in the accompanying proxy statement/prospectus. There can be no assurance that the parties to the Business Combination Agreement would waive any such provision of the Business Combination Agreement if the closing conditions are not met.

Haymaker is providing the accompanying proxy statement/prospectus and accompanying proxy card to its shareholders and warrantholders in connection with the solicitation of proxies to be voted at the Shareholders’ Meeting and at the Warrantholders’ Meeting and any adjournments thereof. Information about the Shareholders’ Meeting, the Warrantholders’ Meeting, the Business Combination and other related business to be considered by Haymaker’s equityholders at the Shareholders’ Meeting and the Warrantholders’ Meeting is included in the accompanying proxy statement/prospectus. Whether or not you plan to attend the Shareholders’ Meeting or the Warrantholders’ Meeting, all of Haymaker’s equityholders are urged to read the accompanying proxy statement/prospectus, including the annexes and other documents referred to therein, carefully and in their entirety. In particular, you should carefully consider the matters discussed under “Risk Factors” beginning on page 48 of the accompanying proxy statement/prospectus.

After careful consideration, the board of directors of Haymaker and the board of managers of Suncrete have each unanimously approved the Business Combination Agreement and related transactions and the board

 

 

of directors of Haymaker has approved the other proposals described in the accompanying proxy statement/​prospectus, determined that it is advisable to consummate the Business Combination and further determined that the Business Combination is in the best interests of the SPAC and its securityholders. The board of directors of Haymaker recommends that its shareholders vote “FOR” the approval of the Business Combination Proposals, “FOR” the issuance of PubCo Class A Common Stock to be issued in connection with the Mergers and PIPE Offering, and “FOR” the other Proposals described in the accompanying proxy statement/prospectus.

Your vote is very important, regardless of the number of SPAC Ordinary Shares or SPAC Public Warrants you own. To ensure your representation at the Shareholders’ Meeting and/or the Warrantholders’ Meeting, please complete, sign, date, and return the applicable enclosed proxy card in the postage-paid envelope provided. If you hold your securities in “street name,” which means your securities are held of record by a broker, bank, or other nominee, you should follow the instructions provided by your broker, bank, or nominee to ensure that votes related to the securities you beneficially own are properly counted. Please submit your proxy promptly, whether or not you expect to attend the Shareholders’ Meeting or the Warrantholders’ Meeting.

If you sign, date, and return your proxy card without indicating how you wish to vote, your proxy will be voted FOR each of the Proposals presented at the Shareholders’ Meeting and/or the Warrantholders’ Meeting, as applicable. If you fail to return your proxy card or fail to instruct your bank, broker, or other nominee how to vote, and do not attend the Shareholders’ Meeting or the Warrantholders’ Meeting virtually or in person, the effect will be, among other things, that your securities will not be counted for purposes of determining whether a quorum is present at the applicable meeting and will not be voted. An abstention or broker non-vote will be counted towards the quorum requirement but will not count as a vote cast at the applicable meeting. You can also attend the Meetings virtually and vote online even if you have previously voted by submitting a proxy pursuant to any of the methods noted above. If you are a securityholder of record and you attend the applicable meeting and wish to vote in person or online, you may withdraw your proxy and vote in person or online.

More information about Haymaker, Suncrete, and the proposed transactions is included in the accompanying proxy statement/prospectus. Haymaker urges you to read the accompanying proxy statement/​prospectus, including the financial statements and annexes and other documents referred to therein, carefully and in their entirety.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST DEMAND IN WRITING THAT YOUR PUBLIC SHARES ARE REDEEMED FOR A PRO-RATA PORTION OF THE FUNDS HELD IN THE TRUST ACCOUNT AND TENDER YOUR SHARES TO HAYMAKER’S TRANSFER AGENT AT LEAST TWO BUSINESS DAYS PRIOR TO THE VOTE AT THE SHAREHOLDERS’ MEETING. IN ORDER TO EXERCISE YOUR REDEMPTION RIGHTS, YOU NEED TO IDENTIFY YOURSELF AS A BENEFICIAL HOLDER. 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 THE BUSINESS COMBINATION IS NOT COMPLETED, THEN THESE SHARES WILL BE RETURNED TO YOU OR YOUR ACCOUNT. IF YOU HOLD THE SHARES IN STREET NAME, YOU WILL NEED TO INSTRUCT THE ACCOUNT EXECUTIVE AT YOUR BANK OR BROKER TO WITHDRAW THE SHARES FROM YOUR ACCOUNT IN ORDER TO EXERCISE YOUR REDEMPTION RIGHTS.

On behalf of our board of directors, I thank you for your support and look forward to the successful completion of the Business Combination.

Sincerely,

Christopher Bradley
Chief Executive Officer and Chief Financial Officer

Information about the Shareholders’ Meeting, the Business Combination, and other related business to be considered by Haymaker’s shareholders at the Shareholders’ Meeting is included in the accompanying proxy statement/prospectus.

Whether or not you plan to attend the Shareholders’ Meeting, all of Haymaker’s shareholders are urged to read the accompanying proxy statement/prospectus, including the annexes and other documents referred to

 

 

therein, carefully and in their entirety. In particular, you should carefully consider the matters discussed under “Risk Factors” beginning on page 48 of the accompanying proxy statement/prospectus.

Pursuant to the Existing Organizational Documents, a holder of SPAC Class A Ordinary Shares issued as part of the units sold in Haymaker’s initial public offering (the “Public Shares,” and holders of such Public Shares, the “Public Shareholders”), other than the Initial Shareholders, may request that Haymaker redeem all or a portion of its Public Shares for cash if the Business Combination is consummated. As a holder of Public Shares, you will be entitled to receive cash for any Public Shares to be redeemed only if you:

(a)   hold Public Shares, or if you hold Public Shares through Haymaker units sold in Haymaker’s initial public offering (the “Haymaker Units”), you elect to separate your Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising your redemption rights with respect to the Public Shares;

(b)   submit a written request to Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, in which you (i) request that Haymaker redeem all or a portion of your Public Shares for cash; (ii) identify yourself as the beneficial holder of the Public Shares and provide your legal name, phone number, and address; and

(c)   deliver your Public Shares to Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, physically or electronically through The Depository Trust Company.

Holders must complete the procedures for electing to redeem their Public Shares in the manner prescribed by the Existing Organizational Documents and as described above prior to [•], Eastern Time, on [•], 2026 (two business days before the Shareholders’ Meeting) in order for their Public Shares to be redeemed.

Holders of Haymaker Units must elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising redemption rights with respect to the Public Shares. If Public Shareholders hold their Haymaker Units in an account at a brokerage firm or bank, such Public Shareholders must notify their broker or bank that they elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and warrants, or if a holder holds Haymaker Units registered in its own name, the holder must contact Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, directly and instruct it to do so. The redemption rights include the requirement that a holder must identify itself to Haymaker in order to validly redeem its shares. Public Shareholders (other than the Initial Shareholders) may elect to exercise their redemption rights with respect to their Public Shares whether they vote “FOR” or “AGAINST” the Business Combination Proposals. If the Business Combination is not consummated, the Public Shares will be returned to the respective holder, broker, or bank. If the Business Combination is consummated, and if a Public Shareholder properly exercises its redemption right with respect to all or a portion of the Public Shares that it holds and timely delivers its shares to Continental Stock Transfer & Trust Company, then prior to the Domestication Effective Time, the SPAC will redeem such Public Shares for a per-share price, payable in cash, equal to the pro-rata portion of the trust account established at the consummation of Haymaker’s initial public offering, calculated as of two business days prior to the consummation of the Business Combination. For illustrative purposes, as of the record date, this would have amounted to approximately $[•] per issued and outstanding Public Share. If a Public Shareholder exercises its redemption rights in full, then it will not own Public Shares or shares of PubCo Class A Common Stock following the redemption. See the subsection titled “Extraordinary General Meeting of Shareholders and Special Meeting of Warrantholders — Redemption Rights” in the accompanying proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to exercise your redemption rights with respect to your Public Shares.

The approval of each of the Initial Merger Proposal, Acquisition Merger Proposal, the Domestication Proposal, the Advisory Organizational Documents Proposals, the NYSE Proposal, the 2026 Plan Proposal, the ESPP Proposal, and the Adjournment Proposal are being proposed as an ordinary resolution, requiring the affirmative vote (in person or by proxy) of the holders of a majority of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Approval of each of the Domestication Proposal, Initial Merger Proposal and the Organizational Documents Proposal requires a special resolution under The

 

 

Companies Act (Revised) of the Cayman Islands, requiring the affirmative vote (in person or by proxy) of the holders of at least two-thirds of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Accordingly, a shareholder’s failure to vote in person, online, or by proxy at the Shareholders’ Meeting will have no effect on the outcome of the vote on any of the Proposals, assuming a valid quorum is established. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Shareholders’ Meeting.

YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF SPAC CLASS A ORDINARY SHARES OR SPAC CAYMAN WARRANTS YOU OWN. To ensure your representation at the Shareholders’ Meeting, please complete and return the enclosed proxy card or submit your proxy by following the instructions contained in the accompanying proxy statement/prospectus and on your proxy card. Please submit your proxy promptly, whether or not you expect to attend the Shareholders’ Meeting. If you hold your shares in “street name,” you should instruct your broker, bank, or other nominee how to vote in accordance with the voting instruction form you received from your broker, bank, or other nominee.

After careful consideration, the board of directors of Haymaker has unanimously approved the Business Combination Agreement and related transactions and the other Proposals described in the accompanying proxy statement/prospectus, has determined that it is advisable to consummate the Business Combination, and further determined that the Business Combination is in the best interests of the SPAC and its securityholders. The board of directors of Haymaker recommends that you vote “FOR” the Business Combination Proposals, “FOR” the Organizational Documents Proposal, “FOR” the Advisory Organizational Documents Proposals, “FOR” the NYSE Proposal, “FOR” the 2026 Plan Proposal, “FOR” the ESPP Proposal, and “FOR” the Adjournment Proposal.

At the Warrantholders’ Meeting, Haymaker shareholders will be asked to consider and vote upon the following proposals:

The Warrant Amendment Proposal must be approved by the holders of at least a majority of the outstanding SPAC Warrants. The Warrantholder Adjournment Proposal must be approved by the holders of a majority of the SPAC Warrants that are present and entitled to vote at the Warrantholders’ Meeting. The Warrant Amendment Proposal will only become effective if the Business Combination is approved by Haymaker’s stockholders. If the Business Combination is not approved, the Warrant Amendment will not become effective, even if the Public Warrantholders have approved the Warrant Amendment Proposal.

Haymaker is providing the accompanying proxy statement/prospectus and accompanying proxy card to its warrantholders in connection with the solicitation of proxies to be voted at the Warrantholders’ Meeting and at any adjournments thereof.

SUMMARY TERM SHEET

This summary term sheet, together with the sections titled “Questions and Answers About the Business Combination” and “Summary of the Proxy Statement/Prospectus,” summarizes certain information included in this proxy statement/prospectus, but does not include all of the information that is important to you. You should carefully read this entire proxy statement/prospectus, including the attached annexes, for a more complete understanding of the matters to be considered at the Shareholders’ Meeting.

SPAC is a blank check company incorporated on March 7, 2023 as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination with one or more businesses or entities. For more information about SPAC, see the section titled “Information About SPAC.” When you consider the SPAC Board’s recommendation of the Proposals (as defined below), you should keep in mind that SPAC’s directors and officers have interests in the Business Combination that are different from, or in addition to, the interests of SPAC shareholders generally. SPAC’s directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to shareholders that they approve the Business Combination. Shareholders should take these interests into account in deciding whether to approve the Business Combination. See the subsection titled “The Business Combination — Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination” for additional information. The SPAC Board was aware of and considered these interests, among other matters, in recommending that SPAC shareholders vote “FOR” each of the Proposals.

There are currently 23,425,499 SPAC Class A Ordinary Shares and 5,750,000 SPAC Class B Ordinary Shares issued and outstanding. In addition, there are currently 11,898,800 SPAC Warrants outstanding, consisting of 11,500,000 SPAC Public Warrants and 398,800 private placement warrants. Each whole SPAC Warrant entitles the holder to purchase one whole SPAC Class A Ordinary Share for $11.50 per share. The SPAC Warrants will not become exercisable until 30 days after the completion of an Initial Business Combination, and will expire five years after the completion of an Initial Business Combination or earlier upon redemption or liquidation. Once the SPAC Public Warrants become exercisable, SPAC may redeem the outstanding SPAC Public Warrants, in whole and not in part, for cash in accordance with, and subject to the terms of, the Warrant Agreement. The private placement warrants, however, are non-redeemable so long as they are held by the Sponsor or its permitted transferees. For more information about the terms of the warrants, see the subsection titled “Description of Securities — Warrants — Public Warrants.”

Suncrete is a ready-mix concrete logistics and distribution platform operating across Oklahoma and Arkansas with plans to expand throughout the high-growth U.S. Sunbelt region through acquisitions and organic growth. Suncrete leverages operational scale, technological integration and quality control to serve a diverse base of infrastructure, commercial and residential customers. For more information about Suncrete, see the sections titled “Information About Suncrete” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations of Suncrete.”

On October 9, 2025, SPAC entered into the Business Combination Agreement with Suncrete and the other parties thereto. A copy of the Business Combination Agreement is attached to this proxy statement/​prospectus as Annex A.

Pursuant to the Business Combination Agreement, and subject to the terms and conditions contained therein, the Business Combination will be effected in three steps: (a) on the Closing Date, the Domestication (the time at which the Domestication becomes effective, the “Domestication Effective Time”); (b) on the Closing Date and immediately following the Domestication, the Initial Merger, with SPAC surviving the Initial Merger as a wholly owned subsidiary of PubCo (SPAC, in its capacity as the surviving corporation of the Initial Merger, is sometimes referred to herein as the “Surviving Corporation,” and the time at which the Initial Merger becomes effective, the “Initial Merger Effective Time”); and (c) on the Closing Date and immediately following the Initial Merger and the Acquisition Merger, with Suncrete surviving the Acquisition Merger as a wholly owned subsidiary of New Suncrete. For more information about the Business Combination Agreement and the Business Combination, see the section titled “The Business Combination.”

In connection with the Domestication, SPAC will transfer by way of continuation out of its jurisdiction of incorporation from the Cayman Islands to the State of Delaware by (i) deregistering as a Cayman Islands

For more information about the Business Combination Agreement and the Business Combination, see the section titled “The Business Combination.”

Q:

Why is Haymaker proposing the Business Combination?

​

A:

Haymaker was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization, or similar business combination involving Haymaker and one or more businesses or entities. On July 28, 2023, SPAC completed the IPO of 23,000,000 SPAC Units, including 3,000,000 SPAC Units that were issued pursuant to the underwriters’ exercise of their over-allotment option in full, with each SPAC Unit consisting of one SPAC Class A Ordinary Share and one-half of one warrant, where each whole warrant is exercisable to purchase one SPAC Class A Ordinary Share at a price of $11.50 per share, generating gross proceeds to SPAC of $230,000,000. The underwriters were granted a 45-day option from the date of the final prospectus relating to the IPO to purchase up to 3,000,000 additional units to cover over-allotments, if any, at $10.00 per unit, less underwriting discounts and commissions. The underwriter exercised the over-allotment option in full. Since the IPO, SPAC’s activity has been limited to the search for a prospective Initial Business Combination. The SPAC Board considered a wide variety of factors in connection with its evaluation of the Business Combination, including its review of the results of the due diligence conducted by SPAC’s management and SPAC’s advisors. As a result, the SPAC Board concluded that a transaction with Suncrete would present the most attractive opportunity to maximize value for SPAC’s shareholders. Please see the subsection titled “The Business Combination- Haymaker Board’s Reasons for the Approval of the Business Combination.”

​

Q:

How will New Suncrete be managed and governed following the Business Combination?

​

A:

Following the Business Combination, the New Suncrete Board will be divided into three separate classes, designated as follows:

​

•

the Class I directors will be William Holden, Bretton Johnston and Randall Edgar, and their terms will expire at the annual meeting of stockholders to be held in 2026;

​

•

the Class II directors will be Christopher Bradley and Andrew Heyer, and their terms will expire at the annual meeting of stockholders to be held in 2027; and

​

•

the Class III directors will be Ned N. Fleming, III, Mark R. Matteson and David Rees-Jones, and their terms will expire at the annual meeting of stockholders to be held in 2028.

​

For additional information, please see the section titled “Management Following the Business Combination.”

Q:

Will SPAC obtain new financing in connection with the Business Combination?

​

A:

Concurrently with the execution of the Business Combination Agreement, Haymaker, PubCo, and the PIPE Investors entered into the Subscription Agreements pursuant to which the PIPE Investors committed to subscribe for and purchase shares of PubCo Class A Common Stock at $10.00 per share (or pre-funded warrants in lieu thereof) for an aggregate purchase price of $82.5 million immediately prior to the Closing.

Q:

What equity stake will Haymaker’s current shareholders and the holders of the Haymaker Founder Shares hold in New Suncrete following the consummation of the Business Combination?

​

​

A:

The following table summarizes the pro forma ownership of New Suncrete Common Stock immediately following the Business Combination under five redemption scenarios: no additional redemptions, 25% redemptions, 50% redemptions, 75% redemptions and maximum redemptions. For illustrative purposes, the information in the table also assumes that (i) there are no other issuances of equity interests of SPAC or Suncrete prior to the closing of the Business Combination, (ii) none of SPAC’s Initial Shareholders purchase any additional SPAC Class A Ordinary Shares prior to the closing of the Business Combination and (iii) that the Business Combination closes on February 13, 2026. In addition, the information in this table does not take into account Assumed SPAC Warrants that will remain outstanding following the Business Combination and may be exercised at a later date. The actual results will be within the parameters described by the scenarios above. However, there can be no assurance regarding which scenario will be closest to the actual results. Stockholders will experience additional dilution to the extent PubCo issues additional shares of PubCo Common Stock after the closing of the Business Combination. Stockholders will also experience additional dilution to the extent that the Sponsor elects to convert any amounts outstanding under existing promissory notes into securities of PubCo. The table below excludes shares of PubCo Common Stock that will initially be available for issuance under the 2026 Plan and ESPP and 3,517,253 shares of restricted PubCo Class A Common Stock issuable as Rollover Equity Awards. Please see the sections titled “Summary of the Proxy Statement/Prospectus — Ownership of New Suncrete After the Closing” and “Unaudited Pro Forma Condensed Combined Financial Information” for further information.

each SPAC Class B Ordinary Share, that is issued and outstanding immediately prior to the Domestication Effective Time will convert automatically, on a one-for-one basis, into a share of SPAC Class B Common Stock;

​

(b)

each SPAC Class A Ordinary Share, that is then-issued and outstanding will convert automatically, on a one-for-one basis, into a share of SPAC Class A Common Stock;

​

(c)

each SPAC Cayman Unit that is then issued and outstanding will convert automatically, on a one-for-one basis, into a SPAC Delaware Unit; and

​

(d)

each then issued and outstanding SPAC Cayman Warrant will convert automatically, on a one-for-one basis, into one SPAC Delaware Warrant, pursuant to and in accordance with the Warrant Agreement.

​

At the Initial Merger Effective Time, by virtue of the Initial Merger and without any action on the part of the SPAC, any of the Merger Subs, Suncrete, PubCo or the holders of any of the following securities:

 

11

 

(a)

each share of SPAC Class A Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time will be canceled and converted into one share of PubCo Class A Common Stock;

​

(b)

each share of SPAC Class B Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time will be canceled and converted into one share of PubCo Class B Common Stock;

​

(c)

each then-outstanding and unexercised SPAC Delaware Warrant will automatically be assumed and converted into a warrant to acquire one share of PubCo Class A Common Stock, subject to the same terms and conditions applicable to the corresponding former SPAC Cayman Warrant immediately prior to the Initial Merger Effective Time (each such resulting warrant, an “Assumed SPAC Warrant”); and

​

(d)

each SPAC Delaware Unit issued and outstanding immediately prior to the Initial Merger Effective Time will be detached into one share of PubCo Class A Common Stock and one-half of one Assumed SPAC Warrant.

​

In addition, immediately prior to the Domestication Effective Time, SPAC will redeem all of the issued and outstanding SPAC Public Warrants at $[•] per SPAC Public Warrant in the Warrant Redemption, which redemption will be effected by SPAC by way of an amendment to the Warrant Agreement if the proposal to effectuate such amendment is approved by a majority of the number of the then outstanding SPAC Warrantholders.

Q:

What are the U.S. federal income tax consequences of the Domestication?

​

A:

As discussed more fully below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects of the Domestication on U.S. Holders” the Domestication should qualify as a tax-deferred “reorganization” within the meaning of Section 368(a)(1)(F) of the Code (an “F Reorganization”). The rules governing the U.S. federal income tax treatment of the Domestication are complex and will depend on a holder’s particular circumstances. Section 367(b) of the Code, which applies to the domestication of a foreign corporation in an F Reorganization and imposes U.S. federal income tax on certain U.S. persons in connection with transactions that otherwise would generally be tax-free, may apply with respect to U.S. Holders (as defined below) on the date of the Domestication.

​

Further, the Domestication could be a taxable event for U.S. Holders under the “passive foreign investment company” ​(or “PFIC”) provisions of the Code.

All holders of our Public Shares or SPAC Public Warrants are urged to consult with their tax advisors regarding the potential tax consequences to them of the Domestication and the tax consequences if the Domestication were to fail to qualify as an F Reorganization. For a more complete discussion of the U.S. federal income tax considerations of the Domestication, see the discussion below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations.”

Q: What are the U.S. federal income tax consequences of the Initial Merger?

As discussed more fully below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects of the Mergers on U.S. Holders,” the Initial Merger, together with the Acquisition Merger and the PIPE Offering, should qualify as an integrated part of a transaction described in Section 351 of the Code. The rules governing the U.S. federal income tax treatment of the Initial Merger are complex and will depend on a holder’s particular circumstances.

All holders of our Public Shares or SPAC Public Warrants are urged to consult with their tax advisors regarding the potential tax consequences to them of the Initial Merger and the tax consequences if the Initial Merger were to fail to qualify as an integrated part of a transaction described in Section 351 of the Code. For a more complete discussion of the U.S. federal income tax considerations of the Initial Merger, see the discussion below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations.”

Q:

Why is Haymaker proposing the NYSE Proposal?

​

A:

Haymaker is proposing the NYSE Proposal in order to comply with NYSE listing rules, which require shareholder approval of certain transactions that result in the issuance of 20% or more of a company’s outstanding voting power or shares of common stock outstanding before the issuance of stock or securities. In connection with the Business Combination and the PIPE Offering, New Suncrete may issue up to an aggregate of 40,782,500 shares of PubCo Class A Common Stock. Because 20% or more of Haymaker’s outstanding voting power and outstanding Ordinary Shares may be issued in connection with the Business Combination, Haymaker is required to obtain its shareholders’ approval of such issuances pursuant to NYSE listing rules. See the section titled “Shareholder Proposal No. 6 — The NYSE Proposal” for additional information.

​

Q:

Did the Haymaker Board obtain a third-party valuation or fairness opinion in determining whether or not to proceed with the Business Combination?

​

A:

No. The Haymaker Board did not obtain a third-party valuation or fairness opinion in connection with its determination to approve the Business Combination. Haymaker is not required to obtain an opinion from an independent investment banking firm or another valuation or appraisal firm that regularly renders fairness opinions as the target business is not affiliated with the Sponsor, the Initial Shareholders or Haymaker’s directors and officers. Haymaker’s officers and directors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of Haymaker’s advisors and consultants, enabled them to make the necessary analyses and determinations regarding the Business Combination. In addition, Haymaker’s officers, directors, and advisors have substantial experience with mergers and acquisitions. Accordingly, investors will be relying solely on the judgment of the Haymaker Board in valuing Suncrete and assuming the risk that the Haymaker Board may not have properly valued the business.

​

Q:

What happens if I sell my SPAC Class A Ordinary Shares before the Shareholders’ Meeting?

​

A:

The record date for the Shareholders’ Meeting is earlier than the date that the Business Combination is expected to be completed. If you transfer your SPAC Class A Ordinary Shares after the record date, but before the Shareholders’ Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Shareholders’ Meeting. However, you will not be able to seek redemption of your SPAC Class A Ordinary Shares because you will no longer be able to deliver them for cancellation upon consummation of the Business Combination in accordance with the provisions described in this proxy statement/prospectus and the Existing Organizational Documents. If you transfer your SPAC Class A Ordinary Shares prior to the record date, you will have no right to vote those shares at the Shareholders’ Meeting or seek redemption of those shares.

​

Q:

How has the announcement of the Business Combination affected the trading price of the Haymaker Units, SPAC Class A Ordinary Shares, and SPAC Public Warrants?

​

A:

The closing price of the Haymaker Units, SPAC Class A Ordinary Shares, and SPAC Public Warrants on October 8, 2025, the last trading day before announcement of the execution of the Business Combination Agreement, was $11.51, $11.35, and $0.59, respectively. On the record date, the Haymaker Units, SPAC Class A Ordinary Shares, and SPAC Public Warrants closed at $[•], $[•] and $[•] respectively.

​

Q:

Following the Business Combination, will Haymaker’s securities continue to trade on a stock exchange?

​

A:

The parties anticipate that, following the Business Combination, the PubCo Class A Common Stock and Assumed SPAC Warrants are expected to be listed on the NYSE and the NYSE Texas under the new symbols “RMIX” and “RMIX.W,” respectively, and the Haymaker Units, SPAC Class A Ordinary Shares, and SPAC Warrants will cease trading on the NYSE and will be deregistered under the Exchange Act.

​

 

13

 

Q:

What vote is required to approve the Proposals presented at the Shareholders’ Meeting?

​

​

A:

The approval of each of the Initial Merger Proposal, the Acquisition Merger Proposal, the Domestication Proposal, the Advisory Organizational Documents Proposals, the NYSE Proposal, the 2026 Plan Proposal, the ESPP Proposal, and the Adjournment Proposal is being proposed as an ordinary resolution, requiring the affirmative vote (in person or by proxy) of the holders of a majority of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Approval of the Organizational Documents Proposal requires a special resolution under The Companies Act (Revised) of the Cayman Islands, requiring the affirmative vote (in person or by proxy) of the holders of at least two-thirds of the SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares entitled to vote and actually casting votes thereon at the Shareholders’ Meeting, voting as a single class. Accordingly, a shareholder’s failure to vote in person, online, or by proxy at the Shareholders’ Meeting will have no effect on the outcome of the vote on any of the Proposals, assuming a valid quorum is established. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as votes cast at the Shareholders’ Meeting.

​

Q:

What vote is required to approve the Proposals presented at the Warrantholders’ Meeting?

​

A:

The Warrant Amendment Proposal requires the vote of the registered holders of a majority of the SPAC Warrants issued and outstanding as of the record date. Accordingly, a warrantholder’s failure to vote by proxy or to vote virtually at the Warrantholders’ Meeting, an abstention from voting, or a broker non-vote, will have the same effect as a vote “AGAINST” the Warrant Amendment Proposal.

​

The Warrantholder Adjournment Proposal will be approved and adopted if the holders of a majority of the SPAC Warrants, represented virtually or by proxy and voted thereon at the Warrantholders’ Meeting, vote “FOR” the Warrantholder Adjournment Proposal.

Q:

May the Sponsor, Haymaker’s directors, officers, advisors, or any of their respective affiliates purchase Public Shares in connection with the Business Combination?

​

​

A:

If Haymaker seeks shareholder approval of the Business Combination and does not conduct redemptions in connection with such Business Combination pursuant to the tender offer rules, the Sponsor, and Haymaker’s Initial Shareholders, directors, officers, advisors or their affiliates may purchase Public Shares or public warrants in privately negotiated transactions or in the open market either prior to or following the completion of the Business Combination. There is no limit on the number of shares such Initial Shareholders, directors, officers or their affiliates may purchase in such transactions, subject to compliance with applicable law. If they engage in such transactions, they will not make any such purchases when they are in possession of any material nonpublic information not disclosed publicly or if such purchases are prohibited by Regulation M under the Exchange Act. Haymaker does not anticipate that such purchases, if any, would constitute a tender offer subject to the tender offer rules under the Exchange Act or a going-private transaction subject to the going-private rules under the Exchange Act; however, if the purchasers determine at the time of any such purchases that the purchases are subject to such rules, the purchasers will comply with such rules. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements. None of the funds held in the trust account will be used to purchase shares or public warrants in such transactions prior to completion of the Business Combination. The purpose of any such purchases of shares could be to increase the likelihood of obtaining shareholder approval of the Business Combination or to satisfy a closing condition in an agreement that requires Haymaker to have a minimum net worth or a certain amount of cash at the closing of the Business Combination, where it appears that such requirement would otherwise not be met, provided that any shares purchased would not be permitted to vote in favor of the Business Combination. The purpose of any such purchases of public warrants could be to reduce the number of public warrants outstanding or to vote such warrants on any matters submitted to the warrantholders for approval in connection with our Business Combination. Any such purchases of our securities may result in the completion of the Business Combination that may not otherwise have been possible. In addition, if such purchases are made, the public “float” of Haymaker’s Class A Common Shares or

​

 

14

 

warrants may be reduced and the number of beneficial holders of Haymaker’s securities may be reduced, which may make it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange. For more information, see the subsection titled “The Business Combination — Potential Purchases of Public Shares.”

Q:

How many votes do I have at the Shareholders’ Meeting?

​

​

A:

Haymaker’s shareholders are entitled to one vote at the Shareholders’ Meeting for each SPAC Class A Ordinary Share or SPAC Class B Ordinary Share held of record as of [•], 2026, the record date for the Shareholders’ Meeting. As of the close of business on the record date, there were 23,425,499 outstanding SPAC Class A Ordinary Shares, which are held by Public Shareholders, and 5,750,000 outstanding SPAC Class B Ordinary Shares, which are held by the Initial Shareholders.

​

Q:

What constitutes a quorum at the Shareholders’ Meeting?

​

A:

Holders of one third of SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares issued and outstanding and entitled to vote at the Shareholders’ Meeting, present in person, online, or by proxy, constitute a quorum. In the absence of a quorum, the Shareholders’ Meeting shall stand adjourned to the same day in the next week at the same time and/or place or to such other day, time and/or place as the SPAC Board may determine. As of the record date for the Shareholders’ Meeting, [•] SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares, in the aggregate, would be required to achieve a quorum. Abstentions will count as present for the purposes of establishing a quorum with respect to each Proposal.

​

Q:

What constitutes a quorum at the Warrantholders’ Meeting?

​

A:

A quorum of Haymaker’s SPAC Public Warrantholders is necessary to hold a valid meeting. A quorum will be present at the Warrantholders’ Meeting if holders of at least a majority of the SPAC Public Warrants will count as present for the purposes of establishing a quorum.

​

Q:

How will the Sponsor and Haymaker’s directors and officers vote?

​

A:

The Sponsor and certain of Haymaker’s directors and officers have agreed to vote any SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares owned by them in favor of the Business Combination and the other Proposals. Currently, they own approximately 22% of Haymaker’s outstanding SPAC Class A Ordinary Shares and SPAC Class B Ordinary Shares, in the aggregate. Please see the subsection titled “The Business Combination — Related Agreements.”

​

Q:

What interests do the current officers and directors of Haymaker have in the Business Combination?

​

A:

When you consider the SPAC Board’s recommendation of the Proposals, you should keep in mind that SPAC’s officers and directors have interests in the Business Combination that are different from, or in addition to, those of other shareholders generally. SPAC’s directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to shareholders that they approve the Business Combination. Shareholders should take these interests into account in deciding whether to approve the Business Combination. See the subsection titled “The Business Combination — Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination” for additional information. The SPAC Board was aware of and considered these interests, among other matters, in recommending that SPAC shareholders vote “FOR” each of the Proposals. These interests include, among other things:

​

​

•

the fact that the Sponsor holds 797,600 private placement units, consisting of 398,800 private placement warrants (provided, that such warrants will be conveyed to Dothan Independent in the Sponsor Distribution, as provided in the Sponsor Subscription Agreement) and 797,600 private placement shares, acquired at an aggregate purchase price of $7,976,000, which, if unrestricted and freely tradeable, would be valued at approximately $9,418,856, based on the most recent closing prices of the SPAC Public Warrants and the SPAC Class A Ordinary Shares on November 7, 2025 of $1.00 per warrant and $11.31 per share, respectively (prior to giving effect to the Sponsor Distribution);

​

 

15

 

•

the fact that the Sponsor and SPAC’s officers and directors have agreed to not redeem any SPAC Class A Ordinary Shares held by them in connection with a shareholder vote to approve the Business Combination;

​

•

the fact that the Sponsor paid an aggregate of $25,000 for 5,750,000 SPAC Founder Shares (provided, that 2,800,000 SPAC Founder Shares will be conveyed to Dothan Independent in the Sponsor Distribution, as provided in the Sponsor Subscription Agreement), and that such SPAC Founder Shares could have a significantly higher value at the time of the Business Combination, which if unrestricted and freely tradable would be valued at approximately $65,032,500, based on the most recent closing price of the SPAC Class A Ordinary Shares of $11.31 per share on November 7, 2025 (prior to giving effect to the Sponsor Distribution);

​

•

if the Trust Account is liquidated, including in the event SPAC is unable to consummate an initial business combination within the required time period, the Sponsor has agreed to indemnify SPAC to ensure that the proceeds in the Trust Account are not reduced below $10.00 per Public Share, or such lesser amount per Public Share as is in the Trust Account on the liquidation date, by the claims of (a) any third party (other than SPAC’s independent registered public accounting firm) for services rendered or products sold to SPAC or (b) a prospective target business with which SPAC has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement, but only if such a third party or target business has not executed a waiver of all rights to seek access to the Trust Account;

​

•

the fact that the Sponsor and SPAC’s officers, directors and advisors will be reimbursed for out-of-pocket expenses incurred in connection with activities on SPAC’s behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations;

​

•

the fact that the Sponsor and SPAC’s officers, directors and advisors will lose their entire investment in SPAC if an Initial Business Combination is not completed within the Combination Period.

​

•

the fact that the Sponsor has invested an aggregate of $8,001,000 (consisting of $25,000 for the SPAC Founder Shares and $7,976,000 for the private placement units), which means that the Sponsor and Haymaker’s officers and directors stand to make a significant profit on their investment and could potentially recoup their entire investment in Haymaker even if the trading price of the PubCo Class A Common Stock was as low as approximately $[•] per share (after giving effect to the transfer to Dothan Independent of the Dothan Founder Shares and Dothan Assumed Warrants following the Sponsor Distribution and assuming the loans and out-of-pocket expenses described below are repaid and reimbursed, respectively, by Haymaker). Therefore, the Sponsor and Haymaker’s directors and officers may experience a positive rate of return on their investment, even if our Public Shareholders experience a negative rate of return on their investment;

​

​

•

the fact that after the Business Combination, assuming there are no redemptions of Public Shares in connection with the Business Combination, the Sponsor will beneficially own approximately 1.2% of the PubCo Class A Common Stock. Please see the section titled “Summary of the Proxy Statement/​Prospectus — Ownership of New Suncrete After the Closing” for additional information;

​

•

the fact that the Sponsor and Haymaker’s directors and officers may be incentivized to complete the Business Combination, or an alternative initial business combination, with a less favorable company or on terms less favorable to shareholders, rather than to liquidate, which would cause the Sponsor to lose its entire investment. As a result, the Sponsor may have a conflict of interest in determining whether Suncrete is an appropriate business with which to complete a business combination and/or in evaluating the terms of the Business Combination;

​

•

the fact that the Sponsor and Haymaker’s officers and directors (or their affiliates) have made, and may make in the future, working capital and extension loans to Haymaker. As of September 30, 2025, the Sponsor has loaned an aggregate of approximately $1,880,000 to Haymaker under unsecured promissory notes to fund operating and transaction expenses in connection with the Business Combination and fund payments into the Trust Account, in accordance with the Existing Organizational Documents, to extend the date by which Haymaker must consummate an initial business combination, and may make additional loans after the date of this proxy statement/

​

 

16

 

prospectus for such purposes. If the Business Combination is not consummated and another business combination is not otherwise completed, these working capital loans may not be repaid and would be forgiven except to the extent there are funds available to Haymaker outside of the Trust Account;

​

•

the fact that pursuant to the Existing Organizational Documents, Haymaker has renounced any interest or expectancy of Haymaker in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for both Haymaker and any individual serving as a director or officer of Haymaker, about which any such director or officer acquires knowledge. In the course of their other business activities, Haymaker’s officers and directors may have become aware of other investment and business opportunities which might have been appropriate for presentation to Haymaker as well as the other entities with which they were affiliated. Haymaker’s management had pre-existing fiduciary duties and contractual obligations and if there was a conflict of interest in determining to which entity a particular business opportunity should be presented, any entity with whom Haymaker’s management had a pre-existing fiduciary obligation would have been presented the opportunity before Haymaker was presented with it (see the subsection titled “Fiduciary Duties of Haymaker’s Directors and Officers” for more information). Haymaker does not believe, however, that the fiduciary duties or contractual obligations of Haymaker’s officers or directors materially affected Haymaker’s search for a business combination, including the negotiation or recommendation thereof or the provision of advice in connection therewith;

​

•

the fact that the Sponsor transferred an indirect interest in a portion of its SPAC Founder Shares and all of its private placement warrants to Dothan Independent;

​

•

the anticipated service of Andrew Heyer and Christopher Bradley as directors of New Suncrete following the Business Combination, and the compensation that they will receive for such service; and

​

•

the fact that Haymaker’s existing directors and officers will be entitled to indemnification and the continuation of Haymaker’s directors’ and officers’ liability insurance after the Business Combination.

​

For more information regarding certain conflicts of interests of SPAC and its affiliates relating to the business combination and the other proposals to be presented at the special meeting, see “The Business Combination — Interests of the Sponsor and Haymaker Directors and Officers in the Business Combination.”

Q:

What happens if I vote against the Business Combination Proposals?

​

A:

Under the Existing Organizational Documents, if the Business Combination Proposals are not approved and Haymaker does not otherwise consummate an alternative Initial Business Combination within the Combination Period, Haymaker will be required to (a) cease all operations except for the purpose of winding up; (b) 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 held in the Trust Account and not previously released to Haymaker (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then public shares in issue, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (c) liquidate and dissolve as promptly as reasonably possible following such redemption, subject to the approval of Haymaker’s remaining shareholders and the Haymaker Board.

​

Q:

Do I have redemption rights?

​

A:

Pursuant to the Existing Organizational Documents, a Public Shareholder may request that Haymaker redeem all or a portion of its Public Shares for cash if the Business Combination is consummated. As a holder of Public Shares, you will be entitled to receive cash for any Public Shares to be redeemed only if you:

​

•

hold Public Shares or, if you hold Public Shares through Haymaker Units, you elect to separate your Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising your redemption rights with respect to the Public Shares;

​

 

17

 

•

submit a written request to Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, in which you (i) request that New Suncrete redeem all or a portion of your Public Shares for cash and (ii) identify yourself as the beneficial holder of the Public Shares and provide your legal name, phone number, and address; and

​

•

deliver your Public Shares to Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, physically or electronically through The Depository Trust Company (“DTC”).

​

Holders must complete the procedures for electing to redeem their Public Shares in the manner described above prior to 5:00 p.m., Eastern Time, on [•], 2026 (two business days before the Shareholders’ Meeting) in order for their shares to be redeemed.

Holders of Haymaker Units must elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising redemption rights with respect to the Public Shares. If Public Shareholders hold their Haymaker Units in an account at a brokerage firm or bank, such Public Shareholders must notify their broker or bank that they elect to separate the Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants, or if a holder holds Haymaker Units registered in its own name, the holder must contact Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, directly and instruct it to do so. The redemption rights include the requirement that a holder must identify itself to Haymaker in order to validly redeem its shares. Public Shareholders (other than the Initial Shareholders) may elect to exercise their redemption rights with respect to their Public Shares regardless of whether they vote “FOR” or “AGAINST” the Business Combination Proposals. If the Business Combination is not consummated, the Public Shares will be returned to the respective holder, broker, or bank. If the Business Combination is consummated, and if a Public Shareholder properly exercises its redemption right with respect to all or a portion of the Public Shares that it holds and timely delivers its shares to Continental Stock Transfer & Trust Company, then prior to the Domestication Effective Time the SPAC will redeem such Public Shares for a per-share price, payable in cash, equal to the pro rata portion of the Trust Account, calculated as of two business days prior to the consummation of the Business Combination. For illustrative purposes, as of the record date, this would have amounted to approximately $[•] per issued and outstanding Public Share. If a Public Shareholder exercises its redemption rights in full, then it will not own Public Shares or shares of PubCo Class A Common Stock following the redemption. See the subsection titled “Extraordinary General Meeting of Shareholders and Special Meeting of Warrantholders — Redemption Rights” for the procedures to be followed if you wish to exercise your redemption rights with respect to your Public Shares.

If you are a holder of SPAC Class A Ordinary Shares and you exercise your redemption rights, such exercise may not result in the loss of any SPAC Public Warrants that you may hold. The amount of SPAC Class A Ordinary Shares redeemed will have no impact on your ability to exercise your redemption rights. Assuming the maximum redemption scenario where 23,425,499 SPAC Class A Ordinary Shares are redeemed, the SPAC Public Warrants retained by such redeeming holders would have an aggregate market value of approximately $23,425,499 based upon the closing price of $1.00 per warrant as of November 7, 2025. Additional shares of PubCo Class A Common Stock may be issuable in the future, upon the exercise of the Assumed SPAC Warrants, after the consummation of the Business Combination. The issuance of such shares could adversely impact the market price of PubCo Class A Common Stock. Furthermore, while the exercise of redemption rights by holders will not decrease the amount of Assumed SPAC Warrants, it will reduce the amount of cash in the trust account, which may heighten such impact. See “Risk Factors — Risks Related to the Business Combination and Haymaker” for further discussion of the risks related to the Assumed SPAC Warrants retained by such redeeming holders.

Q:

Will how I vote affect my ability to exercise redemption rights?

​

A:

No. You may exercise your redemption rights whether you vote your SPAC Class A Ordinary Shares for or against or abstain from voting on the Business Combination Proposals or any other Proposal described in this proxy statement/prospectus. As a result, the Business Combination can be approved by shareholders who will redeem their shares and no longer remain shareholders.

​

 

18

 

Q:

How do I exercise my redemption rights?

​

​

A:

In order to exercise your redemption rights, you must (a) if you hold your SPAC Class A Ordinary Shares through Haymaker Units, elect to separate your Haymaker Units into the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising your redemption rights with respect to the Public Shares and (b) prior to 5:00 p.m., Eastern Time, on [•], 2026 (two business days before the Shareholders’ Meeting), tender your shares physically or electronically and submit a request in writing that Haymaker redeem your Public Shares for cash to Continental Stock Transfer & Trust Company, Haymaker’s transfer agent, at the following address:

​

Continental Stock Transfer & Trust Company
1 State Street, 30th Floor
New York, New York 10004-1561
Attention: Alwyn Burton
Email: aburton@continentalstock.com

Notwithstanding the foregoing, a Public Shareholder, together with any of his, her, or its affiliates or any other person with whom it is acting in concert or as a “group” ​(as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to his, her, or its shares or, if part of such a group, the group’s shares, in excess of the 15% threshold without the prior written consent of Haymaker. Accordingly, all Public Shares in excess of the 15% threshold beneficially owned by a Public Shareholder or group will not be redeemed for cash. In order to determine whether a shareholder is acting in concert or as a group with any other shareholder, Haymaker will require each Public Shareholder seeking to exercise redemption rights to certify to Haymaker whether such shareholder is acting in concert or as a group with any other shareholder. Shareholders seeking to exercise their redemption rights and opting to deliver physical certificates should allot sufficient time to obtain physical certificates from the transfer agent and time to effect delivery. It is Haymaker’s understanding that shareholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. However, Haymaker does not have any control over this process and it may take longer than two weeks. Shareholders who hold their shares in street name will have to coordinate with their bank, broker, or other nominee to have the shares certificated or delivered electronically.

Holders of outstanding Haymaker Units must separate the underlying SPAC Class A Ordinary Shares and SPAC Public Warrants prior to exercising redemption rights with respect to the Public Shares. If you hold Haymaker Units registered in your own name, you must deliver the certificate for such units or deliver such units electronically to Continental Stock Transfer & Trust Company with written instructions to separate such units into Public Shares and SPAC Public Warrants. This must be completed far enough in advance to permit the mailing of the Public Share certificates or electronic delivery of the Public Shares back to you so that you may then exercise your redemption rights with respect to the Public Shares following the separation of such Public Shares from the Haymaker Units.

If a broker, dealer, commercial bank, trust company, or other nominee holds your Haymaker Units, you must instruct such nominee to separate your Haymaker Units. Your nominee must send written instructions by facsimile to Continental Stock Transfer & Trust Company. Such written instructions must include the number of Haymaker Units to be split and the nominee holding such Haymaker Units. Your nominee must also initiate electronically, using DTC’s DWAC (deposit withdrawal at custodian) system, a withdrawal of the relevant Haymaker Units and a deposit of the corresponding number of Public Shares and SPAC 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 following the separation of such Public Shares from the Haymaker Units. While this is typically done electronically on 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.

Any demand for redemption, once made, may be withdrawn at any time until the deadline for exercising redemption requests and, thereafter, with Haymaker’s consent, until the vote is taken with respect to the Business Combination. If you delivered your Public Shares for redemption to the transfer agent and decide within the required timeframe not to exercise your redemption rights, you may request that the

 

19

 

transfer agent return the shares (physically or electronically). You may make such request by contacting Haymaker’s transfer agent at the email address or address listed under the question “Who can help answer my questions?” below.

Q:

What are the U.S. federal income tax consequences of exercising my redemption rights?

​

​

A:

The receipt of cash by a beneficial holder of PubCo Class A Common Stock in redemption of such stock will be taxable event for U.S. federal income tax purposes in the case of a U.S. Holder (as defined below) and could be a taxable event for U.S. federal income tax purposes in the case of a non-U.S. Holder (as defined below). Please see the discussion below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects to U.S. Holders of Exercising Redemption Rights” or “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects to Non-U.S. Holders of Exercising Redemption Rights,” as applicable, for additional information. All Holders considering the exercise of their redemption rights should consult with their tax advisors with respect to the U.S. federal income tax consequences of exercising such redemption rights.

​

Because the redemption of stock from U.S. Holders that exercise their redemption rights will occur prior to the Domestication and the Initial Merger, such redemption will be treated for U.S. federal income tax purposes as being made by a non-U.S. corporation (SPAC). Please see the discussion below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects to U.S. Holders of Exercising Redemption Rights” or “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects to Non-U.S. Holders of Exercising Redemption Rights,” as applicable, for additional information. The tax considerations for U.S. Holders with respect to the Domestication and the Initial Merger are discussed more fully below under the caption “The Business Combination — Material U.S. Federal Income Tax Considerations —  Effects of the Domestication on U.S. Holders” and “The Business Combination — Material U.S. Federal Income Tax Considerations — Effects of the Mergers on U.S. Holders” respectively.

All Holders of Public Shares considering exercising their redemption rights are urged to consult with their tax advisors with respect to the potential tax consequences to them of the Initial Merger and the exercise of their redemption rights.

Q:

What happens if a substantial number of Public Shareholders vote in favor of the Business Combination and exercise their redemption rights?

​

A:

Public Shareholders are not required to vote in respect of the Business Combination Proposals in order to exercise their redemption rights. Accordingly, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Shareholders are reduced as a result of redemptions by Public Shareholders.

​

If a shareholder does not redeem their SPAC Class A Ordinary Shares, but other Public Shareholders do elect to redeem, the non-redeeming shareholders would own shares with a lower book value per share. If no Public Shareholders exercise redemption rights with respect to their SPAC Class A Ordinary Shares in connection with the Business Combination, the pro forma book value per share as of [•], 2026 would have been $[•]. If Public Shareholders exercise redemption rights with respect to [•] SPAC Class A Ordinary Shares, representing 25% of the maximum redemption scenario, the pro forma book value per share as of [•], 2026 would have been $[•]. If Public Shareholders exercise redemption rights with respect to [•] SPAC Class A Ordinary Shares, representing 50% of the maximum redemption scenario, the pro forma book value per share as of [•], 2026 would have been $[•]. If Public Shareholders exercise redemption rights with respect to [•] SPAC Class A Ordinary Shares, representing 75% of the maximum redemption scenario, the pro forma book value per share as of [•], 2026 would have been $[•]. If Public Shareholders exercise redemption rights with respect to 100% of the outstanding SPAC Class A Ordinary Shares, representing the maximum redemption scenario, the pro forma book value per share as of [•], 2026 would have been $[•].

Q:

What are the possible sources and the extent of dilution that the Public Shareholders that elect not to redeem their shares will experience in connection with the Business Combination?

​

​

A:

After the completion of the Business Combination, Public Shareholders will own a significantly smaller percentage of New Suncrete than they currently own of Haymaker. Consequently, the Public Shareholders, as a group, will have reduced ownership and voting power in New Suncrete compared to their ownership and voting power in Haymaker. For the potential impact of redemptions on the ownership percentage of Public Shareholders in a range of redemption scenarios, with the maximum redemption scenario representing the maximum number of redemptions after which the Minimum Cash Condition is satisfied, please see “What equity stake will Haymaker’s current shareholders and the holders of the Haymaker Founder Shares hold in New Suncrete following the consummation of the Business Combination?”.

​

Q:

If I am a warrantholder, can I exercise redemption rights with respect to my warrants?

​

A:

No. The holders of SPAC Warrants have no redemption rights with respect to such warrants.

​

Q:

Do I have appraisal rights if I object to the proposed Business Combination?

​

A:

No. There are no appraisal rights available to holders of SPAC Class A Ordinary Shares, SPAC Class B Ordinary Shares, or SPAC Warrants in connection with the Business Combination under the Companies Act (Revised) of the Cayman Islands or the DGCL.

​

Q:

What happens to the funds deposited in the Trust Account after consummation of the Business Combination?

​

A:

If the Business Combination Proposals are approved and the Business Combination is consummated, Haymaker intends to use a portion of the funds held in the Trust Account to pay (a) any transaction costs associated with the Business Combination Agreement and Business Combination (including payment of the Sponsor Notes), (b) taxes and deferred underwriting discounts and commissions from the IPO, and (c) for any redemptions of Public Shares to public shareholders who have properly exercised their redemption rights. The remaining balance in the Trust Account, together with the proceeds from the PIPE Offering, will be used for general corporate purposes of New Suncrete. See the section titled “The Business Combination” for additional information.

​

Q:

What happens if the Business Combination is not consummated or is terminated?

​

A:

There are certain circumstances under which the Business Combination Agreement may be terminated. See the subsection titled “The Business Combination — Termination” for additional information regarding the parties’ specific termination rights. In accordance with the Existing Organizational Documents, if an Initial Business Combination is not consummated within the Combination Period, Haymaker will (a) cease all operations except for the purpose of winding up, (b) 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 held in the Trust Account and not previously released to Haymaker to pay its taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), and (c) as promptly as reasonably possible following such redemption, subject to the approval of Haymaker’s remaining shareholders and the Haymaker Board, liquidate and dissolve, subject in each case of (b) and (c) above to Haymaker’s obligations under The Companies Act (Revised) of the Cayman Islands to provide for claims of creditors and in all cases subject to the other requirements of applicable law.

​

It is expected that the amount of any distribution Public Shareholders will be entitled to receive upon its dissolution will be approximately the same as the amount they would have received if they had redeemed their shares in connection with the Business Combination, subject in each case to Haymaker’s obligations under The Companies Act (Revised) of the Cayman Islands to provide for

 

21

 

claims of creditors and other requirements of applicable law. Holders of the Haymaker Founder Shares have waived any right to any liquidating distributions with respect to those shares.

In the event of liquidation, there will be no distribution with respect to the outstanding SPAC Warrants. Accordingly, the SPAC Warrants will expire worthless.

Q:

When is the Business Combination expected to be consummated?

​

​

A:

It is currently anticipated that the Business Combination will be consummated promptly following the Shareholders’ Meeting to be held on [•], 2026 provided that all the requisite shareholder approvals are obtained and other conditions to the consummation of the Business Combination have been satisfied or waived. For a description of the conditions for the completion of the Business Combination, see the subsection titled “The Business Combination — Conditions to Consummation of the Business Combination Agreement.”

​

Q:

What do I need to do now?

​

A:

You are urged to read carefully and consider the information included in this proxy statement/​prospectus, including the section titled “Risk Factors” and the annexes attached to this proxy statement/​prospectus, and to consider how the Business Combination will affect you as a shareholder. You should then vote as soon as possible in accordance with the instructions provided in this proxy statement/​prospectus and on the enclosed proxy card or, if you hold your shares through a brokerage firm, bank, or other nominee, on the voting instruction form provided by the broker, bank, or nominee.

​

Q:

How do I vote?

​

​

A:

If you were a holder of record of SPAC Class A Ordinary Shares or SPAC Class B Ordinary Shares on [•], 2026, the record date for the Shareholders’ Meeting, you may vote with respect to the Proposals online at the virtual extraordinary general meeting or by completing, signing, dating, and returning the enclosed proxy card in the postage-paid envelope provided. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank, or other nominee, you should follow the instructions provided by your broker, bank, or nominee to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the record holder of your shares with instructions on how to vote your shares or, if you wish to virtually attend the Shareholders’ Meeting and vote online, obtain a proxy from your broker, bank, or nominee.

​

Q:

What will happen if I abstain from voting or fail to vote at the Shareholders’ Meeting?

​

A:

At the Shareholders’ Meeting, a properly executed proxy marked “ABSTAIN” with respect to a particular proposal will count as present for purposes of determining whether a quorum is present. For purposes of approval, failure to vote or an abstention will have no effect on the Proposals, assuming a valid quorum is established.

​

Q:

What will happen if I sign and submit my proxy card without indicating how I wish to vote?

​

A:

Signed and dated proxies received by Haymaker without an indication of how the shareholder intends to vote on a proposal will be voted “FOR” each Proposal being submitted to a vote of the shareholders at the Shareholders’ Meeting.

​

Q:

If I am not going to attend the Shareholders’ Meeting online, should I submit my proxy card instead?

​

A:

Yes. Whether you plan to attend the Shareholders’ Meeting or not, please read this proxy statement/​prospectus carefully, and vote your shares by completing, signing, dating, and returning the enclosed proxy card in the postage-paid envelope provided.

​

 

22

 

Q:

If my shares are held in “street name,” will my broker, bank, or nominee automatically vote my shares for me?

​

A:

No. Under the rules of various national and regional securities exchanges, your broker, bank, or nominee cannot vote your shares with respect to non-discretionary matters unless you provide instructions on how to vote in accordance with the information and procedures provided to you by your broker, bank, or nominee. Haymaker believes the Proposals presented to Haymaker’s will be considered non-discretionary and therefore your broker, bank, or nominee cannot vote your shares without your instruction. Your bank, broker, or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide.

​

Q:

May I change my vote after I have submitted my executed proxy card?

​

A:

Yes. You may change your vote by sending a later-dated, signed proxy card to Haymaker at the address listed below so that it is received by Haymaker prior to the Shareholders’ Meeting or by attending the Shareholders’ Meeting online and voting there. You also may revoke your proxy by sending a notice of revocation to Haymaker, which must be received prior to the Shareholders’ Meeting.

​

Q:

What should I do if I receive more than one set of voting materials?

​

A:

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

​

Q:

Who can help answer my questions?

​

A:

If you have questions about the Proposals or if you need additional copies of the proxy statement/​prospectus or the enclosed proxy card you should contact Haymaker’s proxy solicitor at:
