Suncrete and Haymaker Acquisition Corp. 4 Announce Entering Into Non-Redemption Agreements with Certain Institutional Investors

DALLAS, March 25, 2026 /PRNewswire/ -- Concrete Partners Holding, LLC ("Suncrete" or the "Company"), a ready-mix concrete logistics and distribution platform strategically located in Oklahoma and Arkansas, and Haymaker Acquisition Corp. 4 (NYSE: HYAC) ("Haymaker"), a publicly traded special purpose acquisition company, today announced that they have entered into non-redemption agreements ("Non-Redemption Agreements") with certain institutional investors, pursuant to which, among other things, the investors agreed to acquire an aggregate of 4.4 million Class A ordinary shares of Haymaker initially included as part of the units sold in Haymaker's initial public offering ("Public Shares") from shareholders of Haymaker, either in the open market or through privately negotiated transactions, at a price no higher than the redemption price per share payable to public shareholders who exercise redemption rights with respect to their Public Shares, prior to the closing date of the Company's business combination with Haymaker ("Business Combination"), to waive their redemption rights and hold the Public Shares through the closing date of the Business Combination, and to abstain from voting and not vote the Public Shares in favor of or against the Business Combination.

Suncrete intends to pay to the shareholders that sell Public Shares in connection with the Non-Redemption Agreements an amount equal to the difference between the actual redemption price for the Public Shares and the price at which such sellers sell the Public Shares to the Investors. As a result of the Non-Redemption Agreements and after giving effect to the aggregate fees that Suncrete has agreed to pay the Investors, Haymaker is expected to receive net proceeds of approximately $10.75 per non-redeemed Public Share. Haymaker may enter into additional Non-Redemption agreements on similar terms. Assuming that the Investors acquire all of the Public Shares they have agreed to purchase and that the previously announced PIPE investment is consummated for aggregate proceeds of $105.5M, the parties anticipate that the Minimum Cash Condition will be satisfied upon consummation of the Business Combination.

The Company is expected to close its previously announced Business Combination with Haymaker in April 2026. Upon closing of the Business Combination, the combined company will be named Suncrete, Inc. ("PubCo") and is expected to trade on Nasdaq under the ticker symbol "RMIX."

Ned N. Fleming, III, Executive Chairman of Suncrete, commented, "Today's announcement underscores strong institutional investor confidence in Suncrete, our best-in-class management team, and our high-performance, scalable ready-mix concrete platform. We believe Suncrete's disciplined growth strategy focused on increasing market share, driving organic expansion, and entering new markets through accretive acquisitions, positions the company to deliver sustained, compounding shareholder value over the long term."
