Japan's largest and world's #3 steel producer; parent of Standard Steel LLC (the only North American forged rail wheel producer, acquired 2011). Also blocked from acquiring US Steel Corporation (Biden administration denied in January 2025 on national security grounds). The irony: US regulators blocked Nippon Steel from buying a general US steel company for 'national security' reasons, while Nippon Steel already wholly owns the company that provides 100% of the forged steel wheels for US freight railcars — a product with no domestic alternative. Nippon Steel is also a major rail producer for Japanese and global markets.

Skyworks Solutions Inc. (Irvine CA; Nasdaq: SWKS; ~$3.8B revenue FY2024; formed 2002 by merger of Alpha Industries and Conexant's wireless division) is the world's third-largest GaAs RF semiconductor company. Skyworks is heavily weighted toward smartphone RF ICs (power amplifiers, front-end modules for Samsung, Huawei era, Apple secondary supplier) and has been expanding into IoT (smart home, industrial IoT) and automotive RF. Skyworks operates a GaAs fabrication facility in Newbury Park CA — one of the few remaining US-soil compound semiconductor fabs producing at commercial scale. Skyworks also uses WIN Semiconductors (Taiwan) as a foundry partner for wafer production overflow. Skyworks' revenue profile is among the most Apple-dependent in the semiconductor industry: Apple historically represented ~60-65% of Skyworks' annual revenue, though this has declined as Broadcom expanded Apple RF content and Skyworks diversified.

Southwire Company LLC (private, HQ Carrollton GA; ~$8B+ revenue; founded 1950 by Roy Richards Sr.) is the United States' largest wire and cable manufacturer AND the inventor of the SCR (Southwire Continuous Rod) continuous copper rod casting process (patented 1963). The SCR process — which feeds molten cathode copper into a continuous casting wheel and immediately hot-rolls to 8mm rod — was developed at Carrollton and Southwire licenses SCR technology globally; most of the world's rod mills outside the Properzi licensees use SCR-derived processes. Southwire operates multiple rod mills in the US (Carrollton GA primary; also Hawesville KY, Russellville AR). As the US's dominant domestic rod supplier, Southwire supplies many US cable manufacturers that cannot source elsewhere. Southwire Carrollton faced EPA Superfund listing due to historical copper smelting/refining waste; the site has since been remediated.
