  • Shift: Thesis extends one layer further up: above GEV (gas-turbine assembler — already a key_ticker since 2026-05-02 Crusoe/Lochmiller capture) sits a metallurgy chokepoint. Single-crystal nickel-superalloy blades require 90-week vacuum-furnace lead times, cost $600K/set, and per @Gaurab only 3 companies on Earth can build them. HWM (Howmet, Engine Products segment) is one. ATI is the alloy supplier feeding that capability. Same physics-first / find-the-monopoly-bottleneck archetype as EHV transformers (NuttyCLD/FrontierMap convergence) and GOES electrical steel (CLF Butler) — different layer, same shape.
  • Effect on thesis: Added HWM + ATI to ai-power.json (40 stocks total). Both deep-dived 2026-05-06. Cohort framing: GEV (already core) is the visible OEM; HWM is the upstream blade caster ($97.2B mcap, 24.5% FCF margin, 100% beat rate, 60.3 RSI, +63% 1y, +488% 3y); ATI is the alloy layer above HWM ($21.2B mcap, 19.6% FCF margin, +131% 1y, +583% 5y, +102pp 1y alpha). Both medium-conviction — moats are real but multi-bagger pricing + insider selling argue for cohort sizing not flagship. Picks-and-shovels of picks-and-shovels of the AI-power thesis. Open questions: verify China $42B / 30hr-vs-4000hr engine-life claims; identify the 3 single-crystal blade casters globally; quantify HWM Engine Products IGT vs aero mix; quantify ATI customer concentration.
  • Per-ticker: HWM ↑ (new key_ticker; upstream blade caster). ATI ↑ (new key_ticker; alloy supplier). GEV reaffirmed (now framed as middle layer of 3-layer upstream stack).
