What these concentrations mean together
updated 2026-06-24The company's concentration profile is deeply embedded in a single end-market — aerospace and defense — with additional layers of customer and sub-market concentration within that universe. Revenues from aerospace and defense represented 96% of total net revenues in 2025, a high share by disclosed size and structural in character: the company's manufacturing capabilities, certifications, and customer relationships are purpose-built for this industry, making the tilt an enduring feature of the business model rather than a transitory allocation. Within that dominant end-market, the customer base is itself concentrated. Revenues from the top ten customers, including Boeing and RTX, were 61% of total net revenues during 2025 — a high share by disclosed size and a dependency by character, given that program wins and production rates at a handful of prime contractors directly govern demand. Looking at individual customers, RTX Corporation generated 18% of 2025 net revenues and Boeing generated 13%, each a low share by disclosed size on a standalone basis, but together representing nearly a third of revenue and making the health and production outlook of both primes a meaningful variable in results. A sub-market concentration adds another layer: revenues from the military and space end-use market represented 58% of total net revenues in 2025, a high share with a mixed character — structural in that the company positions itself for defense programs, but subject to defense budget cycles and program continuity. The overall picture is a tightly coupled aerospace and defense franchise where the budget environment, prime contractor production rates, and program-level decisions at Boeing and RTX are the dominant watchpoints.
