AeroEquity GP, LLC Reports 23.28% Stake in York Space Systems Inc.

On May 15, 2026, AeroEquity GP, LLC, along with Michael Robert Greene and David H. Rowe, filed a Schedule 13G reporting a significant new ownership stake in York Space Systems Inc. (YSS). The reporting persons beneficially own 30,196,088 shares of Common Stock, representing 23.28% of the company's outstanding shares. This position is held through various AE Industrial Partners funds, which are ultimately controlled by AeroEquity GP, LLC and its managing members, Greene and Rowe. The filing also discloses complex "group" dynamics. While the reporting persons directly control 23.28%, they may be deemed part of a larger group due to a Director Nomination Agreement with Dirk Wallinger and various voting agreements. If these affiliated holdings are included, the collective group could be deemed to beneficially own approximately 105,542,882 shares, or 81.38% of the company. However, the reporting persons explicitly disclaim beneficial ownership of shares held by Mr. Wallinger and the other voting agreement parties. The reported event occurred on March 31, 2026.
