What LMB does
LMB is a French specialty manufacturer of aerospace-grade high-performance fans, blowers, electric motors, and specialized rotating machines serving commercial aviation, military/defense, helicopter, naval, and emerging space and UAV programs. Founded over 60 years ago and headquartered in Malemort sur Corrèze, France, LMB operates a portfolio of four core cooling product families — HYPERFANS (80mm–300mm axial fans), OPTIFANS (25mm–80mm compact fans), THINFANS (50mm–120mm thin-profile fans), and Centrifugal Blowers — alongside a complementary line of customized electric motors including servo, torque, and actuator motors. All products are qualified against MIL-STD-810, MIL-STD-704, MIL-STD-461, RTCA DO-160, DEF STAN, NATO STANAG, and GAM EG13 standards, with options for IP68 protection, integrated speed sensors, failure detection, current limitation, and extensive mechanical/electrical customization within reportedly 48-hour response windows.
The company holds AS9100/ISO 9100 quality certification, EASA Part 21G production organization approval, and EASA Part 145 repair station approval, enabling it to operate across the full lifecycle of aerospace components from design and prototyping through production, aftermarket spares, and repair/overhaul. Its commercial model combines direct engineering-led sales to aerospace and defense OEMs (Airbus, Boeing, Comac, ATR, Leonardo, Dassault Aviation, Airbus Helicopters) with a global distributor network of representatives in Italy, Israel, India, Turkey, Japan, Taiwan, the UK, and direct offices in the US, Singapore, and China. Nearly 100% of revenue comes from proprietary designs, and LMB offers over 1,500 qualified off-the-shelf products.
LMB was acquired by Loar Holdings Inc. (NYSE: LOAR) on December 23, 2025, for €367 million in cash plus assumption of net debt, financed via cash on hand and a new $445 million incremental term loan. Loar expects LMB to generate approximately $60 million in revenue and approximately $30 million in Adjusted EBITDA for fiscal year 2026, implying ~50% EBITDA margins consistent with Loar's portfolio of niche aerospace parts suppliers. Post-acquisition, LMB operates as a wholly-owned subsidiary and continues to serve its existing aerospace and defense customer base from France with regional sales coverage spanning North America, Europe, the Middle East, and Asia-Pacific.
