Defense Giants Lag Despite Iran Conflict’s Billion-Dollar Munitions Spend

Elevated valuations alongside a budget pivot toward AI, drones and space curb enthusiasm for the primes.

Overview

  • The five largest U.S. defense contractors are down about 1% on average since the conflict began despite a surge in operational demand.
  • The first four days of fighting reportedly cost nearly $11 billion, including roughly $5.7 billion on Patriot and THAAD interceptors.
  • Rapid inventory depletion has raised logistical concerns, with reports indicating possible reallocation of air-defense assets from South Korea.
  • Major contractors had already climbed about 50% since mid-2024 and several trade near roughly 26 times forward earnings, tempering further gains.
  • Spending priorities favor smaller defense-tech firms as budgets grow for AI, drones and space, and a new executive order restricts buybacks and dividends until delivery performance is proven.
