Graham Corporation GHM

GHM Company Overview

Graham Corporation (NYSE: GHM) is a U.S.-based engineering and manufacturing company that designs and produces mission-critical fluid, power, heat transfer, and vacuum technologies for the defense, energy, aerospace, and process industries. The company operates primarily through its engineered-to-order manufacturing capabilities, supplying highly specialized equipment for applications that require reliability under extreme operating conditions. Graham’s operations have increasingly focused on U.S. naval defense programs, while also maintaining exposure to commercial markets such as refining, petrochemicals, power generation, and space-related applications.

The company’s principal revenue drivers include naval nuclear propulsion equipment, vacuum and heat transfer systems, cryogenic and turbomachinery technologies, and aftermarket services. Graham strengthened its defense and aerospace positioning through the acquisition of Barber-Nichols, LLC, which expanded the company into turbomachinery, cryogenic pumps, and aerospace propulsion components. Founded in 1936 and headquartered in Batavia, New York, Graham evolved from a vacuum equipment supplier serving industrial markets into a diversified engineered-products company with increasing exposure to long-cycle defense and aerospace programs.
