Amentum Holdings, Inc. reported third quarter fiscal 2026 results with revenue of $3,490 million, down 2% year over year, primarily due to contract transitions to unconsolidated joint ventures and prior-year divestitures, partially offset by new awards in critical digital infrastructure and space systems.
