Trasteel and Sizzle advance proposed combination with confidential SEC filing

Trasteel S.A., the new holding company for Trasteel Holding and Sizzle Acquisition Corp. II, confidentially delivered a draft Form F-4 to the SEC on September 30, 2026. The draft concerns the companies' previously announced business combination. If completed, Pubco would own both Trasteel and Sizzle II, and its shares are intended to begin Nasdaq trading as TSTL.

The filing begins the SEC review phase for the proposed SPAC transaction. Completion still depends on an effective registration statement and approval by Sizzle II shareholders.
