Pono Capital Four Announces Merger Agreement to Acquire Blackstar Orbital

What Happened

• On August 5, 2026, Pono Capital Four, Inc. (PONO), a SPAC, filed an 8‑K announcing a Merger Agreement with Blackstar Orbital Technologies Corporation (Blackstar). Under the agreement, after PONO domesticates from the Cayman Islands into Delaware, Pono Four Merger Sub will merge into Blackstar, making Blackstar the surviving company and a wholly‑owned subsidiary of PONO. Following the Business Combination, PONO will be renamed “Blackstar Orbital Corporation” (Pubco).
• The transaction is structured around a $380,000,000 Base Purchase Price to be paid in Parent Common Shares (the Aggregate Merger Consideration). Closing is subject to PONO and Blackstar shareholder approvals, customary regulatory clearances (including HSR), effectiveness of a Form S‑4 / proxy statement, conditional Nasdaq listing approval, and completion of the domestication step. PONO expects to file the Registration Statement promptly and Blackstar must deliver audited and interim financials by August 31, 2026 for inclusion in that filing.

Key Details

• Base Purchase Price: $380,000,000 (paid in Parent Common Shares; number of shares = $380M ÷ Redemption Price).
• Escrow and incentives: ~25% of the Aggregate Merger Consideration will be held in escrow for six years to secure indemnity/litigation claims; an additional equity incentive plan reserve of up to 6,000,000 Parent Common Shares is provided (does not reduce merger consideration).
• Timing/conditions: PONO Parent Outside Closing Date is Dec 31, 2026; Blackstar Company Outside Closing Date is Mar 31, 2027. Domestication to Delaware must occur at least one business day before closing.
• Governance and lockups: Post‑closing Pubco board will have five directors (three designated by Blackstar, one by the Sponsor, one independent mutually agreed). Sponsor (Mehana Ventures LLC) and certain Company stockholders entered into support agreements to vote in favor of the deal; lock‑up and registration rights agreements are contemplated at closing.

Why It Matters

• For PONO investors: the deal converts the SPAC into an operating company (renamed Blackstar Orbital Corporation) focused on reusable spacecraft and in‑space logistics, with an implied $380M base equity consideration; shareholder votes, regulatory approvals and Nasdaq listing are required before the combined company can begin public trading under the new name.
• For Blackstar stakeholders and potential investors: equity consideration, long escrow holdback (six years) and an additional 6M‑share incentive pool affect near‑term liquidity and long‑term equity structure. The domestication step (Cayman → Delaware) and requirement to deliver audited financials by Aug 31, 2026 are key closing prerequisites.
• Risks and next steps are procedural and material: completion depends on shareholder approvals, SEC clearance of the S‑4/proxy, antitrust and other governmental approvals, and meeting Nasdaq listing conditions — any of which could delay or prevent closing.
