dMY Squared Technology Group, Inc. 8-K

What Happened
dMY Squared Technology Group, Inc. (DMYY) filed an 8-K on March 20, 2026, reporting the closing of its business combination (the SPAC Merger) and a resulting change in control: the company is now a wholly owned subsidiary of Holdco (Horizon Quantum Holdings Ltd.). The filing also documents a warrant assignment and amendment that transfers the Company’s warrant rights to Holdco, and reports public shareholder redemptions tied to the transaction.

Key Details

• 1,403,777 SPAC public shares were redeemed at approximately $11.82 per share, for an aggregate redemption payment of about $16.47 million. (Special meeting held March 17, 2026.)
• A Warrant Assumption Agreement dated March 19, 2026 assigned the Company’s Existing Warrant Agreement to Holdco; warrants now represent rights to acquire Holdco’s Class A ordinary shares (Continental Stock Transfer & Trust Company is warrant agent).
• Change in control occurred at closing: dMY became a wholly owned subsidiary of Holdco. As a result, dMY adopted Second Amended and Restated Articles of Organization.
• Board/officer changes: Darla Anderson, Francesa Luthi, Constance Weaver and Harry You ceased as dMY directors/officers; Horizon’s board named Joseph Fitzimons (CEO), Si‑Hui Tan (Chief Science Officer), and Greg Gould (CFO), and appointed Joseph Fitzimons, Danielle Lambert, Jill Turner and Harry You as Horizon directors.

Why It Matters
This 8-K confirms that the SPAC combination has closed and control has shifted to Holdco (Horizon), which affects governance, where warrants convert to rights in the new Holdco, and how investors’ equity interests are structured going forward. The $16.47M in redemptions shows the cash returned to public holders who elected out of the deal. Holdco will provide the full transaction disclosures on Form 20-F, which investors should review for complete financial and operational details.
