Nortech Systems is a contract manufacturer — also known as an Electronic Manufacturing Services (EMS) provider — that builds complex electronic and electromechanical products for OEM customers. Nortech's core products include wire and cable assemblies (including fiber optic and hybrid copper/fiber cables), printed circuit board assemblies, and fully integrated "box build" systems. Nortech targets OEMs that need a manufacturing partner with strong quality credentials and the ability to handle a high mix of complex, low-to-moderate volume products, rather than commodity, high-volume production. Medical devices and medical imaging together account for over 50% of net sales, making them Nortech's largest end markets; aerospace and defense and industrial make up the remainder. Nortech operates a three-tier global manufacturing footprint across the US, Mexico, and China, routing production to the most cost-effective location based on customer needs and IP considerations. Revenue is driven by volume shipped and product complexity, while profitability is heavily influenced by plant utilization, product mix, and manufacturing efficiency. Nortech is investing in proprietary fiber optic technologies — including its EBX platform for harsh-environment data transmission and its AOX hybrid fiber-plus-copper cable — targeting medical imaging, aerospace, and industrial automation applications. Nortech also sees near-shoring trends as a tailwind, given its USMCA-compliant US and Mexico footprint. One customer accounted for approximately 32% of net sales in FY25.
