Loar designs and manufactures niche aerospace and defense components that are essential to aircraft and defense systems, serving the commercial aircraft, business jet and general aviation, and defense end markets. The company generates approximately 55% of its revenue from aftermarket products—highly profitable, recurring sales that extend across decades following initial aircraft certification—while the remaining 45% comes from original equipment manufacturer (OEM) sales; roughly 89% of sales derive from proprietary products where Loar holds leading market positions, with no single customer or aircraft platform accounting for more than a small fraction of revenue. The company grows through organic innovation and operational efficiency as well as through disciplined acquisitions that add complementary aerospace and defense businesses with strong aftermarket potential, leveraging the fragmented supply chain and the high switching costs created by regulatory certification requirements and long product lifecycles.
