**Citable summary**: Howmet Aerospace's confirmed revenue counterparties include GE 에어로스페이스, RTX plus 2 undisclosed/aggregate relationships. Per the valuechain.wiki graph: 4 revenue edges, backed by 3 dated sources, 1 of them primary filings (as of 2026-07-12).

### GE 에어로스페이스 (high)  → /ge-aerospace.md
- note: The relationship that shows why Howmet is a bottleneck supplier to the jet-engine supercycle: it supplies single-crystal turbine airfoils and castings for GE Aerospace's LEAP and GEnx engines, ~11% of third-party sales (2025). As one of few holders of scarce single-crystal casting capacity, GE's narrow-body engine ramp and aftermarket spares demand feed straight into Howmet's Engine Products growth.

- [confirms] SEC / Howmet Aerospace (EN, filing, published 2026-02-12) https://www.sec.gov/Archives/edgar/data/4281/000000428126000012/hwm-20251231.htm: "RTX and GE Aerospace each represented ~11% of third-party sales (2025)."

### RTX (high)  → /rtx.md
- note: Supplies castings and forgings for RTX (Pratt & Whitney) GTF geared-turbofan engines — tied with GE as the largest customer (~11% of third-party sales, 2025). The GTF narrow-body ramp and maintenance cycle drive growth, but RTX-side engine recall/MRO issues also flow straight through as a volume variable — a two-edged dependence.

### 상용 항공 엔진 슈퍼사이클·애프터마켓 (high)
- note: The cycle itself that drives results: Engine Products revenue of $4,327M is half of the $8,269M total and the growth core. On top of the narrow-body (LEAP/GTF) new-engine ramp, high-margin MRO/spares (aftermarket) demand compounded to produce FY2025 operating income of $2,046M (+25%) and net income of $1,508M (+31%). Boeing 737 MAX rate approval (FAA, Oct 2025) is the upside switch for structures and fastener volume.
- [mentions] Morgan Stanley / consensus (EN, research, published 2026-05-08) https://www.marketbeat.com/stocks/NYSE/HWM/forecast/: "Consensus Strong Buy, avg ~$306 (MS $315); margin upside from defense, IGT, data centers."

### 산업용 가스터빈 OEM (IGT·데이터센터 전력) (mid)
- note: A second growth axis where datacenter power scarcity layers onto the aero cycle: advanced-cooling, coated large IGT turbine parts are ~11% of revenue (oil & gas / gas turbines). Howmet is one of few suppliers of blades to IGT primes such as Siemens Energy, GE Vernova and Mitsubishi Heavy, and AI-datacenter-driven gas build-outs are lifting this demand. (Per-OEM contract shares undisclosed; no cpid assigned.)
