IEH Corporation operates as a family managed business with a focus on quality and innovation. The company also offers design and engineering support to help customers integrate its connectors into complex electronic systems.

The company generates revenue primarily from the sale of its Hyperboloid connectors, high speed connectors, and hybrid power/signal interconnects, as well as from engineering services for custom interconnect designs. For the fiscal year ended March 31 2025, approximately 65.7% of sales were for defense applications, 19.9% for commercial aerospace, and 14.4% for commercial space launch, medical, oil and gas, and industrial markets. The company sells its products directly to original equipment manufacturers and through a network of independent sales representatives and distributors. During the fiscal year ended March 31 2025, two customers accounted for 31.9% of net revenues, with each representing 17.8% and 14.1% respectively. International sales represented approximately 5.7% of net sales for the same period. The company maintains a backlog of orders that reflects anticipated shipments within the next twelve months, which helps manage production planning. The backlog amounted to approximately $12,445,000 at March 31 2025, down from $18,285,600 at March 31 2024 due to lower defense orders and slower commercial aerospace recovery.
