EEI Manufacturing

What EEI Manufacturing does

EEI Manufacturing, now operating as Impact ES–Clearwater, is a U.S.-based contract electronics manufacturer specializing in advanced PCB assembly and end-to-end aerospace manufacturing services. Founded in 1993, the company has accumulated over 25 years of experience serving aerospace, defense, and homeland security customers with prototype development and full-turnkey production of electronic assemblies designed to meet stringent quality, traceability, and compliance standards.

The company's core technology centers on advanced PCB assembly for mission-critical applications, complemented by value-add engineering services intended to accelerate time to market. EEI positions itself as an extension of its customers' organizations, emphasizing agility, world-class quality, and alignment with the U.S. Defense Department's "Better Buying Power" affordability initiative. Its offerings span design through production, supporting program needs across the defense electronics, security systems, military equipment, and adjacent aerospace domains.

EEI was acquired by Impact Electronic Solutions, a strategic operating company headquartered in Lake Oswego, Oregon, and now operates as one node in a multisite U.S. manufacturing network spanning Florida, Rhode Island, Oregon, Washington, and California. The company generates revenue through project-based, quote-based contract manufacturing engagements with enterprise defense and aerospace buyers, with no public pricing or named customer disclosures available. Leadership is anchored by President Dave Matheny, and the Clearwater site employs 11–50 people as part of the broader Impact Electronics platform.
