What Happened?
On January 29, 2026, York Space Systems completed its initial public offering (“IPO”), with an opening price of $34 per share.

On May 11, 2026, Wolfpack Research published a short report alleging that the Pentagon's decision to eliminate the space program responsible for the majority of York's annual revenue "was rooted in severe disappointment in York" including claims that “York deceived the SDA with false advertising to win its contracts, cut corners, and delivered satellites whose mission-critical-software was not completed." The report states “two former software engineers told us the company sent satellites into space without even knowing if the software was fit to accomplish its basic mission” and “another former employee told us that York would cut corners and use unqualified people, like office administrators and accountants to build parts and perform tests.”

Following this news, shares of York Space Systems are trading as low as $25 per share, a 26% decline from its IPO price of $34 per share.
