About IEH Corp

IEH Corp (ticker: IEHC) is a small-cap industrial company whose shares are associated with the U.S. market and referenced in SEC filings as a company whose stock is traded on a NYSE/NASDAQ-type U.S. listing venue. The company is incorporated in New York and headquartered in Brooklyn, New York, United States. IEH’s core business is the design, development, and manufacture of printed circuit board connectors, power and signal contacts, and custom interconnect solutions for demanding applications. In practice, it is a specialized component supplier focused on high-reliability environments where mechanical robustness, electrical integrity, and long service life matter. IEH traces its origins to 1941 in New York City, when the Offerman family founded a tool and die business to support wartime production. Over time, the company moved into transistor and tube sockets, then CRT sockets for the emerging television industry, before pivoting in the late 1960s to Hyperboloid connector technology. That transition shaped the company’s modern identity. Today, IEH positions itself as one of the world’s leading producers of Hyperboloid connectors and contacts, and it emphasizes decades of engineering experience in mission-critical applications. The company’s principal product lines include high-reliability printed circuit board connectors, signal and power contacts, and custom interconnect products designed to customer specifications. SEC disclosures indicate that IEH sells directly to original equipment manufacturers and also through distributors and independent representatives. Its end markets include defense, aerospace, space, medical, industrial, test equipment, and commercial electronics. This mix gives IEH a niche position in markets where specification compliance and reliability are often more important than commodity pricing. Competitive conditions are described as fragmented, with many small and medium-sized connector manufacturers competing across overlapping product categories. IEH’s main competitive advantage is its Hyperboloid contact design, which the company says is used across its connector portfolio and is suited to harsh, high-stress operating conditions. Another strength is its willingness to engineer custom solutions for customers with specialized application needs. Geographically, IEH serves customers in the United States and abroad, including Canada, the European Union, Southeast Asia, Central Asia, and the Middle East. The company also relies on a sales network of independent representatives and distributors to extend its reach. Recent notable items include ongoing SEC filings in 2025 and 2026, including Form 4 insider transaction reports, which keep investor attention focused on ownership changes and corporate governance. Recent annual-report disclosures also indicate that defense applications account for a substantial share of sales, underscoring IEH’s role as a niche supplier to technically demanding end markets in the United States and beyond.
