On October 9, AST SpaceMobile, Inc. fell 6.18% in regular trading to $53.44 per share, with turnover of $157 million. The decline was driven by news that SpaceX acquired nationwide 800MHz low-band spectrum licenses from Grain Management, a transaction approved by the FCC. This move marks SpaceX's formal entry into the mobile operator market and intensified market fears of worsening competition in the satellite-to-smartphone segment.

The low-band spectrum approval further heightened concerns about the long-term profitability of AST SpaceMobile's business model. The company designs and manufactures satellites and is building a space-based cellular broadband network accessible by standard smartphones. Sector peers showed mixed performance, with SpaceX rising 2.91% and Anterix up 3.46%, while Lumen Technologies fell 2.25%.
