The company reported net income of $1.6M for the quarter, driven by $2.6M of interest income and offset by $1.0M in operating costs.

Haymaker Acquisition Corp. 4 (HYAC) amended its disclosure to detail a planned business combination with Suncrete, structured as a Delaware domestication followed by two mergers that will make Suncrete a wholly owned subsidiary of New Suncrete (PubCo).

HYAC shareholders will have the right to redeem their Class A shares ahead of the shareholder vote.

Financing includes a PIPE of approximately $82.5 million in PubCo Class A shares (and, in certain cases, pre-funded warrants) to close immediately prior to the Acquisition Merger. Support agreements commit key Suncrete holders and the SPAC sponsor to vote for the deal and include lock-ups releasing 33.33% of covered securities at six months and another 33.33% at nine months after closing. The sponsor agreed to waive anti-dilution rights and to forfeit up to 333,333 PubCo Class A shares tied to anchor commitments at the Initial Merger effective time.
