York Space Systems faces a critical challenge after the US Space Force effectively cancelled the satellite programme that accounted for virtually all of its revenue. The Pentagon has decided not to fund the latest stage of the Space Development Agency’s (SDA) Transport Layer programme, instead pivoting to a new architecture known as the Space Data Network (SDN). The shift leaves the recently listed satellite manufacturer scrambling to prove it can compete with Elon Musk’s SpaceX for a place in the successor system.
Programme cancellation and the shift to the Space Data Network
The SDA, a branch of the US Space Force, had been building out the Transport Layer – a constellation of between 300 and 500 low Earth orbit satellites operating at altitudes of 750km to 1,200km, designed for targeting and military communications. York Space Systems was a key contractor, delivering 21 satellites for Tranche 1 and securing a contract for 62 satellites for the Tranche 2 Alpha variant. According to the company’s filings, 96% of its $386.2 million revenue in 2025 came from the SDA’s Transport Layer programme.
That revenue stream is now under direct threat. The US Space Force has decided not to fund the planned Tranche 3 of the Transport Layer, effectively ending the programme. It is instead pursuing the Space Data Network (SDN), a multi-orbit, hybrid satellite communications architecture intended to integrate military and commercial systems into a unified secure data network. The Space Force has requested billions of dollars in research, development and procurement funding for the SDN in fiscal year 2027.
The problem for York is that SpaceX, with its Starshield offering, has already been positioned as the incumbent provider for the SDN backbone. According to research by Wolfpack Research, no competitive solicitation for a second backbone vendor has been reported in initial plans. York would therefore need to convince the Pentagon that it can build satellites more cheaply and efficiently than SpaceX – a task made harder by the company’s persistent losses and the allegations of poor performance that, according to Wolfpack, prompted the Pentagon to abandon the Transport Layer in the first place.
Wolfpack Research published a short report on 11 May 2026 alleging that York Space Systems had deceived the SDA, cut corners and delivered satellites with incomplete mission-critical software. The research firm claimed the Pentagon’s decision to dismantle the SDA programme stemmed from severe disappointment with York’s work. Following that report and the company’s subsequent earnings disclosures, several law firms have launched investigations into potential securities law violations by York Space Systems.
Financial losses mount as acquisitions drain reserves
Even before the programme cancellation, York Space Systems was chronically loss-making with scant progress towards breaking even. Operating losses increased by 50% between 2023 and 2025, according to the company’s financial statements. For the twelve months ending 30 September 2025, York reported a net loss of $81.31 million on revenue of $357.46 million; the full-year net loss for 2025 was $84.537 million. The situation worsened sharply in the first quarter of 2026: net loss widened to $114.8 million, compared with $11.7 million in the same period a year earlier, largely due to stock-based compensation and costs associated with its January 2026 initial public offering.
Gross margins have also deteriorated. They fell to 19% in the first quarter of 2026, a four-percentage-point decline year-on-year, attributed to unfavourable “estimate at completion” adjustments. Adjusted EBITDA swung from a profit in 2025 to a loss of $3.6 million in the first quarter of 2026.
York has attempted to strengthen its position through a string of acquisitions that are likely to deplete its remaining cash reserves. In July 2025 it acquired ATLAS Space Operations, Inc. for an undisclosed sum. In March 2026 it bought Orbion Space Technology, a satellite propulsion system manufacturer, for approximately $74.9 million. A month later it purchased ALL.SPACE, a provider of satellite communications terminals, for $355 million. In May 2026 it acquired Solestial, a maker of space solar cells. The company may also start issuing more shares to raise cash, a sign of financial strain.
Despite these difficulties, the stock was trading at almost eight times sales at the time of the original analysis – a valuation more typical of a fast-growing, profitable company than one at risk of losing its dominant customer.
Stock stumbles after volatile debut
York Space Systems went public on 29 January 2026 via an IPO priced at $34 per share, raising approximately $629 million and giving the company a market capitalisation of roughly $4.34 billion. The stock opened at $38, above the offer price, but quickly fell. It later recovered to trade 25% above its listing price before suffering a dramatic collapse. As of 15 May 2026, the share price had fallen by around 17% in a single day to close at $24.02, well below both its 200-day and 50-day moving averages. The 52-week range is between a high of $44.54 and a low of $16.93.
The sharp decline follows the Wolfpack Research allegations and the company’s disclosure of a widened quarterly loss. An analyst had previously suggested shorting the stock at $24.02, with a stop-loss trigger at $33.52, implying a maximum downside of £950 per £100 bet at that price level.
