Core business model and product characteristics
- Emphasis on proprietary products with substantial aftermarket content.
- Aftermarket revenues are a major component of sales and are generally higher margin and more stable than OEM sales.
- Typical aircraft program life cycle creates long product life: design into aircraft, then roughly 25–30 years of aftermarket sales; platform life often 20–30 years; product life cycle typically exceeds 50 years.
- Net sales mix (FY2026): about 90% from proprietary products; aftermarket accounted for approximately 55% of net sales.
Strategy and value drivers

- Offer highly engineered, value-added products and communicate customer value to support pricing.
- Decentralized organizational structure with operating units grouped into three segments.
- Disciplined acquisition strategy focused on proprietary aerospace components with aftermarket content.
- Efficient capital allocation, using cash flow to fund operations, acquisitions, special dividends and/or debt reduction.
