Type: Acquisition · Technology: Solar · Country: United States · Announced: 2026-05-20
York Space Systems, a Denver-based aerospace and defense contractor, signed a definitive agreement to acquire Solestial, an Arizona-based manufacturer specializing in next-generation silicon solar technology optimized for orbital environments. The transaction is expected to close in the second quarter of 2026, with York issuing up to 2.35 million shares of common stock and funding the remaining purchase price in cash. Solestial will operate as a wholly owned subsidiary from its Tempe, Arizona facility, maintaining uninterrupted production and commercial pipeline for ultra-thin silicon modules.

Financial details were submitted in regulatory filings, with the deal structured to accelerate Solestial's production scaling and technical integration.
