Defense Backlogs Face Supply Chain Risk From China Mineral Curbs

## Catalyst Analysis: China Mineral Restrictions Impact Defense Sector - China has restricted the export of 12 critical minerals essential for advanced defense technologies, including directed-energy weapons. This move introduces potential supply chain vulnerabilities for U.S. defense contractors.

## Impact on Defense Contractors ### Winners, Losers & Uncertainty Raytheon Technologies (RTX) reported an 18% revenue increase in Q2 to $8.27 billion, with a substantial backlog of $289 billion. However, CEO Chris Calio highlighted supply chain access to critical minerals as a key factor for executing this backlog and future contracts. Competitors Lockheed Martin ($LMT+WL) and Boeing (BA) have also flagged concerns regarding rare-earth mineral availability in their second-quarter risk disclosures, particularly as they secure significant deals like a $35 billion THAAD contract.

### Risk Watch — legal/timeline The full impact of China's mineral restrictions on the defense sector remains to be seen. Defense contractors are navigating these new trade dynamics, which could affect production timelines and costs for advanced munitions and laser weapon systems. The dependence on a limited supply of key minerals creates uncertainty for the long-term execution of defense contracts.
