| Top risks | Axiom Space's AxEMU is ahead in lunar variant maturity — Collins may end up as the ISS suit, not the lunar suit.; Suit development has historically slipped — NASA OIG flagged the xEVAS critical path multiple times. | ISS deorbit planned ~2030 compresses the market window for ISS-attached modules; SpaceX Crew Dragon is the sole current transport option — pricing and availability risk | Pratt & Whitney GTF powder-metal disk inspection program: 1,200+ engines required early removal/shop visits for inspection of defective powder-metal discs — RTX took $3B+ charges in 2023; residual liability and airline compensation claims remain a risk.; Raytheon missile production capacity constraints limit revenue growth in the near term despite record $107B defense backlog; supply chain bottlenecks on Patriot/AMRAAM components could delay deliveries. |
| Next catalyst | ISS xEVAS suit Earth-simulated environment demo (2026) | Axiom Mission 5 (Ax-5) — next private astronaut mission to the ISS (NET 2027-01) | Raytheon defense backlog conversion and margin recovery (2026-Q2) |
