HWM Howmet Aerospace
Superb engine-parts franchise, but at 10x sales the price assumes perfection beyond defensible margins.
The story
Howmet is the dominant supplier of single-crystal turbine airfoils, aerospace fasteners, structural castings and forged truck wheels. It has an oligopoly moat built on decades of metallurgical know-how, long qualification cycles, and sole-source positions on LEAP, GTF and military engines. The business is in a profitable mid-life growth phase. Its growth is driven by the narrowbody production ramp and a lengthening engine spares tail as the installed fleet ages and ships more parts per shop visit. Margins have already roughly doubled since 2021 on pricing power and mix.
Year-one growth of 13% matches the ~13% five-year CAGR and current OEM build rates plus spares demand, fading to a 4% terminal rate below the risk-free rate. The margin rises modestly from 26.9% to 29%: pricing power is real, but I don't extrapolate the steep run-up. I use a 14-year horizon because engine spares annuities and sole-source positions give an unusually durable moat. Sales-to-capital of 1.8 is above the reported 1.08 because the business is capex-light (capex ~4.7% of sales) and needs little incremental capital. Even with these generous inputs, the value probably lands well below the $231 price, so the market is pricing in more growth or margin than I can defend.

Key risks
- Boeing/Airbus production stumbles or GTF/LEAP rate cuts slow OE volume
- Margin mean-reversion as customers push back on price increases and labor and alloy costs rise
- Valuation at ~10x sales leaves no room for a cyclical air-traffic downturn
Catalysts
- Narrowbody rate increases toward 60+/month and a widebody recovery lift engine content
- Spares share of engine revenue keeps rising, supporting margins near 30%
