Insights

M&A Specialist

TL;DR: Yorkville executed a material business combination agreement involving Crypto.com and TMTG; a Form S-4 will follow for shareholder approval.

The agreement dated August 25, 2025, represents a definitive step toward combining the SPAC with operating entities including Crypto.com (Foris Holdings KY Limited) and TMTG. Filing a Form S-4 indicates the company intends to solicit shareholder votes and register securities related to the Transactions. The disclosure is procedural but material: it triggers a formal proxy process and additional SEC filings. The 8-K does not disclose deal economics, consideration, pro forma financials, regulatory approvals, or timing for the shareholder vote, which are necessary to assess valuation, dilution, and financing risk.

Corporate Governance Expert

TL;DR: The company initiated the formal disclosure and proxy process, which will require shareholders to review detailed transaction documents before voting.

The notice emphasizes that shareholders should read the preliminary and definitive proxy/prospectus once filed, reflecting standard governance and disclosure practice for SPAC business combinations. The 8-K identifies parties and the planned S-4 registration but omits key governance details such as voting record date, board recommendations, conflicts of interest, and any shareholder redemption procedures. Those items will be important for investors and are expected in forthcoming filings.
