Introductory Note

The Business Combination

On April 8, 2026 (the “Closing Date”), Suncrete, Inc. (the “Company”) consummated its previously announced business combination (the “Closing”) pursuant to that certain Business Combination Agreement, dated October 9, 2025 (the “Business Combination Agreement”), by and among the Company, Haymaker Acquisition Corp. 4, a Cayman Islands exempted company (“Haymaker” or “SPAC”), Haymaker Merger Sub I, Inc., a Delaware corporation and a direct wholly owned subsidiary of the Company (“Merger Sub I”), Haymaker Merger Sub II, LLC, a Delaware limited liability company and direct wholly owned subsidiary of the Company (“Merger Sub II”), and Concrete Partners Holding, LLC, a Delaware limited liability company (“Suncrete”), a copy of which is attached to this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference.

Immediately prior to the Closing, on April 8, 2026, Haymaker redeemed all of its issued and outstanding public warrants to purchase Class A Ordinary Shares of Haymaker, par value $0.0001 per share (“SPAC Class A Ordinary Shares” and such warrants, the “SPAC Public Warrants”) in exchange for (i) $2.25 in cash and (ii) 0.075 SPAC Class A Ordinary Shares per SPAC Public Warrant (the “Warrant Redemption”).

Also immediately prior to the Closing, on April 8, 2026, Haymaker transferred by way of continuation out of its jurisdiction of incorporation from the Cayman Islands and domesticated into the State of Delaware (the “Domestication” and the time at which the Domestication became effective, the “Domestication Effective Time”). At the Domestication Effective Time (a) each SPAC Class A Ordinary Share that was issued and outstanding immediately prior to the Domestication Effective Time converted automatically, on a one-for-one basis, into one share of Class A Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class A Common Stock”), (b) each Class B Ordinary Share of Haymaker, par value $0.0001 per share, that was issued and outstanding immediately prior to the Domestication Effective Time converted automatically, on a one-for-one basis, into one share of Class B Common Stock of the post-Domestication SPAC, par value $0.0001 per share (“SPAC Class B Common Stock”), and (c) each then-issued and outstanding private warrant to purchase SPAC Class A Ordinary Shares prior to the Domestication converted automatically, on a one-for-one basis, into one private warrant to purchase SPAC Class A Common Stock (a “SPAC Private Warrant”).

On April 8, 2026, immediately following the Domestication, Merger Sub I merged with and into Haymaker (the “Initial Merger”), with Haymaker surviving the Initial Merger as a wholly owned subsidiary of the Company (the time at which the Initial Merger became effective, the “Initial Merger Effective Time”). At the Initial Merger Effective Time, among other things, (a) Haymaker Sponsor IV, LLC (“Sponsor”) distributed 2,800,000 shares of SPAC Class A Common Stock (the “Dothan Founder Shares”) and 398,800 SPAC Private Warrants to Dothan Independent GP, LP (“Dothan Independent”), (b) each share of SPAC Class A Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time was canceled and converted into one share of Class A Common Stock of the Company, par value $0.0001 per share (“Company Class A Common Stock”), (c) each share of SPAC Class B Common Stock issued and outstanding immediately prior to the Initial Merger Effective Time was canceled and converted into one share of Class B Common Stock of the Company, par value $0.0001 per share (“Company Class B Common Stock” and, together with the Company Class A Common Stock, the “Company Common Stock”) and (d) each then-outstanding SPAC Private Warrant was automatically assumed and converted into a private warrant to purchase one share of Company Class A Common Stock (“Company Warrants”).

On April 8, 2026, immediately following the Initial Merger, Merger Sub II merged with and into Suncrete (the “Acquisition Merger” and, together with the Initial Merger, the “Mergers”, and together with the Domestication, the Warrant Redemption and all other transactions contemplated by the Business Combination Agreement, the “Business Combination” and the time at which the Acquisition Merger became effective, the “Acquisition Merger Effective Time”), with Suncrete surviving the Acquisition Merger as a wholly owned subsidiary of the Company. At the Acquisition Merger Effective Time, among other things, (a) each share of Company Class B Common Stock issued and outstanding immediately prior to the Acquisition Merger Effective Time (other than the Dothan Founder Shares) was converted into and exchanged, on a one-for-one basis, into one share of Company Class A Common Stock, (b) the Company issued 14,117,894 shares of Company Class A Common Stock to members of Suncrete, (c) the Company issued 3,481,776 shares of restricted Company Class A Common Stock upon the cancelation and conversion of the incentive units granted to management of Suncrete (“Rollover Equity Awards”), (d) the Company issued 18,414,609 shares of Company Class B Common Stock to members of Suncrete, and (e) the Company issued 2,500,000 shares of Company Class B Common Stock to Dothan Independent.

In addition, as previously disclosed, the Company previously entered into subscription agreements (the “PIPE Subscription Agreements”) with certain institutional investors (collectively, the “PIPE Investors”), pursuant to which (a) immediately prior to the Acquisition Merger Effective Time, the Company issued and sold to certain of the PIPE Investors in a private placement an aggregate of 11,216,667 shares of Company Class A Common Stock and pre-funded warrants to purchase 2,525,094 shares of Company Class A Common Stock (the “Pre-Funded Warrants”) and (b) at the Acquisition Merger Effective Time, the Company issued and sold to certain of the PIPE Investors in a private placement an aggregate of 6,162,009 shares of Company Class A Common Stock.

Further, as previously disclosed, the Company previously entered into a Securities Exchange Agreement (the “Exchange Agreement”) with holders of Suncrete’s Senior Preferred Units (the “Senior Preferred Units”), pursuant to which the Company agreed to issue an aggregate of 26,000 shares of Series A Convertible Perpetual Preferred Stock, par value $0.0001 per share (the “Series A Preferred Stock”), to such Senior Preferred Unit holders in exchange for their Senior Preferred Units (the “Exchange”). On April 8, 2026, the Exchange occurred immediately prior to the closing of the Acquisition Merger, and the Company issued 26,000 shares of Series A Preferred Stock to the Senior Preferred Unit holders, following the acceptance by the Secretary of State of the State of Delaware of the Certificate of Designation for the Series A Convertible Perpetual Preferred Stock (the “Certificate of Designation”).

In connection with the closing of the Business Combination, holders of 12,628,150 SPAC Class A Ordinary Shares sold in Haymaker’s initial public offering properly exercised their right to have their shares redeemed for a pro rata portion of the trust account holding the proceeds from Haymaker’s initial public offering, and on April 8, 2026, prior to the Domestication, Haymaker redeemed 12,628,150 Class A ordinary shares for $11.57 per share (the “Public Share Redemptions”). As a result, on April 8, 2026, after giving effect to the Public Share Redemptions and payments to holders under prepaid forward agreements and before paying expenses, there was approximately $59 million remaining in the trust account.

As of the Closing Date, following the Public Share Redemptions, the issuance of the shares of Company Class A Common Stock pursuant to the PIPE Subscription Agreements, and the consummation of the Mergers, there were (i) 46,879,768 shares of Company Class A Common Stock issued and outstanding, (ii) 23,714,609 shares of Company Class B Common Stock issued and outstanding, and (iii) Company Warrants to purchase 398,800 shares of Company Class A Common Stock outstanding.
