Northrop Grumman Takes Hit After Boeing Wins F/A-XX Contract

Northrop Grumman's stock price dropped by 4.6% on September 30, 2026, following Boeing's selection for the US Navy's F/A-XX next-generation carrier fighter program.

The award is a major blow to Northrop Grumman, which had been competing for the contract and was widely identified as one of the key competitors. The F/A-XX program is considered a potentially large multi-year opportunity for Boeing.

Northrop Grumman's recent updates pointed to ongoing business momentum, including stronger 2026 guidance after second-quarter results and progress on the Sentinel program. However, the contract outcome was seen as the clearest reason for the company's drop in stock price.
