Activist stake amendment (position change)
Actionable Insight • Neutral

The sponsor's dissolution of its concentrated block removes a potential overhang but also signals that the sponsor's lock-up period has ended and insiders are now free to trade subject to the Joinder's transfer restrictions. Monitor for any Form 144 filings or insider sales from the distributees in the coming weeks.

Executive Summary

Haymaker Sponsor IV LLC distributed its entire stake of 3,564,267 shares of Suncrete Class A Common Stock and 75,000 private placement warrants to its members on October 8, 2026, for no consideration. As a result, the Sponsor no longer holds any Suncrete securities, and each Reporting Person (Andrew R. Heyer, Steven Heyer) now holds less than 5% of the outstanding shares. This is a de-escalation of the sponsor's concentrated position, not an activist campaign update.
