Redwire, AST SpaceMobile, Momentus Rally After SpaceX S‑1

Shares of Redwire, AST SpaceMobile and Momentus rose after SpaceX filed an S‑1 ahead of a June 12 IPO that described plans to scale Falcon 9 and Starship launches, expand satellite manufacturing and roll out Starlink direct-to-cell services. Investors moved into smaller public companies tied to those three business areas.

SpaceX’s prospectus separates its business into launch services, satellite hardware and satellite broadband. The filing sketches higher launch cadence for Falcon 9 and Starship, expanded in-house satellite production and a push to provide direct-to-cell connectivity through Starlink.

Momentus, which provides “last‑mile” delivery using Vigoride orbital transfer vehicles, gained after the filing highlighted increased launch activity. More frequent rideshare opportunities and satellite deployments can raise demand for orbital transfer and in-space insertion services. Momentus’s market capitalization is about $100 million and the company has a thin public float and a high‑beta trading profile.

Redwire, an aerospace contractor that supplies components such as solar arrays, docking mechanisms and space‑qualified 3D printers, saw shares rise after investors focused on the S‑1’s attention to satellite manufacturing and supply chains. Redwire reported first‑quarter revenue of $97 million, up roughly 58% year over year, and a backlog near $498 million.

AST SpaceMobile, which is developing a space‑based cellular broadband network, rallied after the filing emphasized Starlink’s direct‑to‑cell plans. AST SpaceMobile has existing domestic carrier arrangements and formal FCC commercial approval, which investors viewed as positioning it as a public competitor in satellite‑to‑phone services.

Market participants said the S‑1 provided a clearer breakdown of SpaceX’s commercial roadmap, and that clarity prompted revaluation of public companies tied to launch services, manufacturing and satellite broadband. Trading in the three names reflected varied investor interest across those distinct segments as the market awaited SpaceX’s June 12 offering.
