What ESCO Technologies Inc. does

ESCO Technologies Inc. (NYSE: ESE) is a St. Louis-headquartered holding company founded in 1989 that designs and manufactures highly-engineered products across three technology-driven segments: Aerospace & Defense, Utility Solutions Group, and RF Test & Measurement. The Aerospace & Defense segment delivers hydraulic filtration systems, precision fluid control valves, machined components, shock and vibration dampening products, and signature management/power solutions for US and UK Navy submarines and surface ships through subsidiaries including Crissair, PTI Technologies, Mayday Manufacturing, Globe Composite Solutions, ESCO Maritime Solutions, and Westland Technologies. The Utility Solutions Group provides diagnostic instruments, protection testing, condition monitoring equipment, and engineering services for electric utilities and renewable energy project development through Doble Engineering, Morgan Schaffer, NRG Systems, Phenix Technologies, and the Altanova brands (ISA, Techimp), with Megger Group pending acquisition to create a unified electrical asset management platform. The RF Test & Measurement segment supplies electromagnetic shielding and test systems for R&D, regulatory compliance, medical shielding, EMP protection, and security applications via ETS-Lindgren and MPE Limited.

The company generates revenue predominantly through direct B2B sales of engineered hardware products to enterprise customers, with pricing ranging from unit-priced industrial tools (e.g., FLANGEHOG 110 at $7,495, COHOG at $14,995) to large quote-based defense and utility systems. A modest usage-based rental fleet exists for welding end preparation tools. Customers include Boeing, Lockheed Martin, Intel, TSMC, the US Navy, and the UK Royal Navy. ESCO employs over 3,400 people globally and reported FY2025 revenue of $1.1 billion (up 19.2% YoY) with adjusted EPS of $6.03, and is guiding to $1.29B-$1.33B for FY2026. Its business model is anchored in proprietary engineering, multi-year defense and utility certification cycles, and a sustained M&A strategy of acquiring and integrating niche specialty manufacturers while periodically divesting non-core assets (e.g., VACCO Industries to RBC Bearings for $275M in mid-2025).
