Proem Acquisition Corp. I Announces Merger to Acquire Astro Digital ($525M)

What Happened

• On September 26, 2026 (reported in an 8-K on Sept. 28, 2026), Proem Acquisition Corp. I (PAAC) signed a Merger Agreement to acquire Astro Digital US, Inc. for a Base Purchase Price of $525,000,000 plus the Aggregate Exercise Price. The transaction is structured as a domestication of PAAC from the Cayman Islands to Delaware, followed by two merger steps that will leave the combined operating business as a wholly owned subsidiary of PAAC (which will change its name to “Astro Digital, Inc.” or another mutually agreed name).
• The deal includes a committed PIPE financing of 5,000,000 PAAC common shares at $10.00 per share for $50,000,000 in gross proceeds (affiliate/sponsor investors committed $25,000,000). PAAC agreed to use an amount equal to 20% of PIPE proceeds (i.e., $10,000,000) to repurchase a pro rata portion of selling stockholders’ PAAC shares at $10.00 per share.

Key Details

• Merger Agreement dated Sept. 26, 2026; 8‑K filed Sept. 28, 2026. Closing target requires shareholder approvals and SEC filings (Registration Statement/Form S-4).
• Purchase consideration: $525,000,000 plus Aggregate Exercise Price (conversion for in‑the‑money options/warrants) paid in PAAC common shares at $10.00 per share equivalent (Conversion Ratio applies).
• PIPE Financing: 5,000,000 shares at $10.00 = $50,000,000; sponsor affiliates committed $25,000,000; 20% of PIPE proceeds ($10,000,000) reserved for repurchases at $10.00/share.
• Closing conditions include a Minimum Cash Condition of $30,000,000, Nasdaq (or other exchange) conditional listing approval, effectiveness of the Registration Statement, and shareholder approvals. Outside closing date: April 26, 2027 (subject to certain extensions).
• Governance and post-close terms: PAAC’s board will be seven directors (Company designates four, including the Chair); lock-up on certain holders for six months (or until specified market thresholds are met).

Why It Matters

• This transaction converts PAAC from a blank‑check SPAC into an operating public company centered on Astro Digital’s satellite hardware/software and mission services business. The $50M PIPE provides committed capital and the $30M minimum cash requirement must be met for the deal to close.
• Key near‑term milestones for investors: PAAC and Astro Digital shareholder votes, SEC effectiveness of the combined S‑4/proxy, PIPE closing, and Nasdaq listing approval. The repurchase, lock‑ups and Sponsor PIPE commitments will affect post‑close share distribution and short‑term float.
