- Middle East conflict since Feb 2026 disrupting supply of critical commodities like aluminum and rare earth elements, impacting semiconductor industry inputs
- Supply chain dependency on single or limited suppliers for key parts, with risks from export restrictions on Chinese rare earths that could delay production
- Primary competitor Applied Materials, plus ASM International and Tokyo Electron, challenge product acceptance and customer loyalty in key semiconductor equipment markets
- $3.75B senior unsecured notes outstanding with additional $2B commercial paper program and $2B revolving credit, exposing company to leverage and covenant restrictions
