Why should you care about a company that builds satellites if you have never heard of it? Because its customers say they want more of them. Astro Digital’s satellites serve uses such as earth observation, communications, space infrastructure and defense, and one of its platforms has already run AI computing in orbit. Now the company plans to go public through a merger with Proem Acquisition Corp I (Nasdaq: PAAC).

The merger agreement is dated September 26, 2026. Under it, Astro Digital US, Inc. and Proem Acquisition Corp I have entered into a definitive business combination agreement. Upon closing, Proem will be renamed Astro Digital Holdings, Inc., and the combined entity is expected to trade on Nasdaq. The transaction values Astro Digital at a pro forma post-money enterprise value of approximately $587 million. The deal is funded by up to approximately $180 million in gross proceeds. That includes up to $130 million from Proem’s trust account, assuming no redemptions, and approximately $50 million from private investments in public equity, known as PIPE investments. The companies anticipate closing in the first quarter of 2027, subject to certain closing conditions.

To understand the story, one must understand the vehicle. Proem Acquisition Corp I is a special purpose acquisition company, or SPAC. A SPAC is a shell company that raises money in an initial public offering for the purpose of finding a private company to merge with, taking that private company public without a traditional IPO process. Think of a SPAC as a blank check company. It has cash sitting in a trust account, waiting for a target. In this case, the target is Astro Digital. The merger agreement details how the two entities will combine, including how Astro Digital’s shareholders will surrender their shares and receive payment, and how the trust account will be handled.

Astro Digital is not a startup. According to the joint press release, the company has delivered satellites since 2018, and its chief executive refers to 11 years of operating history. It designs, manufactures, and operates mission-configurable satellites for commercial, civil, and defense applications. The company says it has delivered nearly 40 satellites across 16 distinct mission types and has served more than 30 customers. These customers include NASA, the Department of Defense, Boeing, and Sony. The press release highlights several industry firsts. Starcloud-1 carried the first NVIDIA H100 GPU into orbit in November 2025 and has since run large language model training and inference on orbit. Mandrake demonstrated optical inter-satellite links for DARPA and the Space Development Agency. Otter Pup 1 and 2 was a mission demonstration for rendezvous, proximity operations and docking for Starfish Space.

The financial narrative presented by the company is one of unusual efficiency in a sector it says is defined by cash burn. The press release says Astro Digital has grown revenue at a 42% two-year compound annual growth rate, or CAGR, while generating positive adjusted EBITDA, and calls this a rare combination among public space peers. Chris Biddy, Co-Founder and Chief Executive Officer of Astro Digital, said that unlike competitors, the company has delivered nearly 40 satellites profitably, with revenue compounding at 42% annualized over two years. Imran Khan, Chairman and Chief Executive Officer of Proem, added that the business is capital efficient, having built satellites for eleven years without the cash burn that defines most of the sector. The transaction includes a $50 million PIPE investment led by Proem Asset Management and Leon Capital Group, with Proem Asset Management and its affiliates committing $25 million.

This announcement changes the trajectory for both entities. For Astro Digital, Biddy said, the deal will let the company increase its sales force and production capacity and expand into new verticals. For Proem, it provides an operating business to merge with, moving from a shell company to a satellite builder. The merger agreement includes representations and warranties, covenants, and conditions to closing, including the approval of Astro Digital’s shareholders. The document also addresses the treatment of company options, convertible notes, and warrants.

What could this become? If constellations keep multiplying, as Khan suggests, demand for Astro Digital’s platforms could grow with them, and existing customers could place follow-on orders. Biddy says customers continue to expand their constellation plans. If demand for orbital data centers grows, as Biddy mentioned, Astro Digital’s experience with Starcloud-1 could give it a head start in that niche. However, if the closing conditions are not met, or if customer demand slows, the company could face the challenges of being a public entity with high expectations and limited operating history in the public markets.

To our eye, the story is less about the technology and more about the financial discipline. Both executives frame the sector around cash burn. Astro Digital’s claim of positive adjusted EBITDA and a 42% revenue growth rate stands out. The desk’s reading is that the deal is being pitched on this efficiency. Imran Khan, former Chief Strategy Officer of Snap, leads Proem Asset Management and will join Astro Digital’s board of directors after closing. The $587 million valuation is significant, and Biddy points to a backlog that doubled last year in support of the growth story. The desk would ask how sustainable this growth is as the company scales production. The merger agreement includes covenants on conduct of the business pending closing, which set out how the company must operate during the transition.

What to watch: The documents outline the next steps. The deal requires shareholder approval, including from Astro Digital’s shareholders, and the merger agreement provides for a registration statement and proxy statement to be filed. The press release states that the transaction has been unanimously approved. The expected closing is in the first quarter of 2027. Investors should watch for the filing of the proxy statement and registration statement, which should provide more detailed financial information and risk factors. The performance of the stock post-merger will also be a key indicator of market sentiment.

In other words, Astro Digital is using a SPAC merger to go public, pitching positive adjusted EBITDA and fast revenue growth, with plans to add sales staff and production capacity and expand into new verticals.
