About Circor International INC

CIRCOR International Inc. (ticker: CIR) is a U.S.-listed industrial company trading on the NYSE/NASDAQ markets of the United States, focused on mission-critical flow control and motion control solutions. The company occupies a highly technical niche, supplying engineered products used in environments where reliability, safety, and performance are essential. Founded in October 1999, CIRCOR has built its business around a portfolio of recognized brands and a global footprint serving industrial and aerospace customers. Its executive headquarters are in Burlington, Massachusetts, anchoring the company in a major U.S. industrial corridor. CIRCOR’s operations are organized around two core business groups: Aerospace & Defense and Industrial. In Aerospace & Defense, the company designs and manufactures fluid-control components, actuation solutions, and related sub-systems for commercial aviation, military platforms, space applications, and ground-support equipment. In Industrial, CIRCOR serves a broad set of end markets including chemicals, water and wastewater, energy, general industrial processing, and other severe-service applications. Its portfolio spans pumps, valves, controls, and reliability solutions. Key brands include Allweiler, Imo, Houttuin, Hale Hamilton, RTK, Schroedahl, Tushaco, Warren, Zenith, and CIRCOR Aerospace. From a competitive standpoint, CIRCOR differentiates itself less by scale than by engineering depth, application expertise, and exposure to high-specification end markets. The company emphasizes its ability to serve demanding customers with customized solutions, long product life cycles, and aftermarket support. It also highlights a broad global customer base of roughly 100 countries, which supports both direct sales and distribution-led channels. This international reach is strategically important in critical flow-control markets where installed-base relationships and service capabilities matter as much as initial equipment sales. Geographically, CIRCOR has a wide operating presence across the United States, Canada, Europe, Asia, the Middle East, and Africa, with manufacturing and sales facilities spread across multiple countries. That footprint supports a globally diversified revenue base and gives the company access to both developed and high-growth markets. Recent developments have centered on portfolio expansion and international growth. In 2025, CIRCOR completed the acquisition of Swelore Engineering and Hiro Nisha Systems in India, adding diaphragm metering pumps, dosing packages, and high-pressure reciprocating pumps to its Industrial segment and strengthening its position in a key growth market. For investors, CIRCOR remains a specialized industrial technology platform with meaningful exposure to aerospace, defense, chemicals, water infrastructure, and other critical applications.
