IEH Corp

IEH Corporation (hereinafter referred to as “IEH” or the “Company”) began operations in New York, New York in 1941 and was incorporated as a New York corporation in March 1943, when Louis Offerman founded L. Offerman Tool & Die with his two sons, Bernard and Seymour.

In the late 1960’s, IEH bought a license to manufacture Hyperboloid sockets, and began making printed circuit board (“PCB”) connectors for the defense and aerospace industries, in accordance with the MIL-DTL-55302 military specification. We have been making these connectors and variations of them ever since, and today, we are one of the leaders in Hyperboloid connectors and contacts.

In use for nearly 60 years under demanding conditions, Hyperboloid technology has proven itself to be the leading design for integrity and reliability. On avionics platforms, military and commercial aerospace equipment, engine control systems, missiles and torpedoes, vehicular electronics, satellites and rocket launchers, medical devices, industrial and environmental controls, test equipment, pin grid array sockets and countless other rugged applications, Hyperboloid aims to be the highest reliability connector available.

At IEH, we design and manufacture Hyperboloid connectors that not only accommodate, but exceed military and aerospace specification standards. Years after inception, our Hyperboloid solutions continue to prove their reliability and benefits. Our engineers have long provided reliable and innovative Hyperboloid interconnect solutions for defense, commercial, aerospace and medical use.

We are a family managed business, as Louis’ great-grandson, Mr. David Offerman, is the President and Chief Executive Officer, and we believe that we still manufacture the highest quality products for the most demanding environments. But most importantly, we are always looking ahead. We are committed to developing new technology that meets the demands of our fast-paced customers, and we are steadfast about always exceeding our customers’ expectations.

IEH serves customers in the United States and internationally. Our customers include defense contractors, commercial aerospace equipment manufacturers, medical device manufacturers, oil and gas exploration firms, and commercial space launch companies. We sell both directly and through distributors. We maintain a Military Specification QPL (Qualified Product Listing), and an ISO (International Standards Organization) 9001:2015 Certification.

For the fiscal years ended March 31, 2026 and 2025, approximately 63.2% and 65.7%, respectively, of the Company’s sales were for defense applications, 25.2% and 19.9%, respectively, for commercial aerospace, and 11.6% and 14.4%, respectively, for commercial space launch, medical, oil and gas and industrial markets.

New Product Development:

IEH continues to expand the scope and range of its PCB connector offerings. We have also increased the breadth of our products by introducing high-speed connectors for data transmission, as well as hybrid power/signal connectors. New product developments are primarily driven by customer demand. IEH also continues to specialize in custom interconnects designed specifically for customer applications. Our engineers work in conjunction with customer engineers to create, refine and manufacture connectors and interconnect solutions that meet their specific, demanding needs. IEH engineers are renowned for their flexibility and creativity in solving customer interconnect challenges and providing innovative solutions.

Marketing and Sales:

The market for connectors and interconnect devices, domestic and worldwide, is highly fragmented as a result of the manufacture by many companies of a multitude of different types and varieties of connectors and interconnects. For example, connectors include: printed wiring board, rectangular I/O, circular, planar coaxial, IC socket and fiber optic. The Company has been servicing a niche in the market by manufacturing connectors containing Hyperboloid contact designs in the printed wiring board style of connectors.

The Company is continuously experimenting with innovative connection designs, which may cause it to alter its marketing plans in the future if a market should develop for any of its current or future innovative designs. The Company is continually reviewing product lines being sold in the connector and interconnect marketplace. We are committed to expanding our product offering and we consider that many of our current or future custom designs will become product lines.

The Company’s products are marketed to Original Equipment Manufacturers (“OEM”) directly and through authorized representatives and distributors serving primarily the defense, aerospace, medical, space, oil and gas, industrial, test equipment and commercial electronics markets. The Company is also involved in developing new connectors for specific uses, which result from changes in technology. The Company assists customers in the development and design of connectors for specific customer applications. This service is marketed to customers who require the development of connectors and interconnection devices specially designed to accommodate the customers’ own products.

The Company is primarily a manufacturer and its products are essentially basic components of larger assemblies of finished goods. During the year ended March 31, 2026, two customers accounted for 34.0% of the Company’s net revenues, each represented 23.5% and 10.5%, respectively. During the year ended March 31, 2025, two customers accounted for 31.9% of the Company’s net revenues, each represented 17.8% and 14.1%, respectively.

The Company currently employs 17 independent sales representatives and distributors to market its products in all regions in the United States as well as in Canada, the European Union, Southeast Asia, Central Asia and the Middle East. These independent sales representatives also promote the product lines of other electronics manufacturers; however, they do not promote the product lines of manufacturers which compete directly with the Company’s products. These sales representatives accounted for approximately 75% of the Company’s net sales for the fiscal year ended March 31, 2026 (with the balance of Company net sales being generated via direct customer contact).

International sales accounted for approximately 5.8% and 5.7% of net sales for the fiscal years ended March 31, 2026 and 2025, respectively.

We also market our products and capabilities through our website, www.iehcorp.com. Our product series HBH Hybrid Power/Signal Hyperboloid Connectors, has a configuration tool that allows users to build their own hybrid connector and download 3D models to incorporate into their modules.

Backlog of Orders/Capital Requirements:

Our customers typically enter into supply arrangements for the purchase of our products which we will produce and deliver over time. On an as-needed basis, our customers place specific production orders, and these orders are generally filled and shipped within twelve to twenty-four weeks. Our backlog consists of supply arrangements where the anticipated unfulfilled shipping dates are generally within approximately twelve months. Because of the possibility of customer changes in delivery schedules or the cancellation of orders, our backlog as of any particular date may not be indicative of revenue in any future period. The backlog amounted to approximately $27,782,000 at March 31, 2026 as compared to $12,445,000 at March 31, 2025. The increase in total backlog as of March 31, 2026 compared with the previous year is primarily due to increases in defense orders primarily driven by geopolitical conditions around the globe and continued recovery of the commercial aerospace industry as prior production, labor and regulatory issues related to a major airplane producer have been resolved.

A portion of these backlog orders are subject to cancellation or postponement of delivery dates and, therefore, no assurance can be given that actual sales will result from these orders. The Company does not foresee any problems which would prevent it from fulfilling these orders.

Forward-Looking Business Trends:

Our operations are subject to global economic and geopolitical risks. For example, the ongoing and evolving conflicts in Eastern Europe and the Middle East have impacted economic activity as well as the availability and price of raw materials and energy. The Company continues to actively monitor these factors and find ways to mitigate the impact on its operations. The company also continues to monitor and evaluate the evolving situation around imposition of tariffs by the current administration and subsequent Supreme Court ruling(s) against tariff imposition and the resulting impact on sourcing of raw materials and revenue generated from global markets.

For additional information on risk factors that could impact our results, please refer to “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K.

Competition:

The design, development, manufacture and distribution of electrical connectors and interconnection devices is a highly competitive field. The Company principally competes with both large and small companies who also produce high performance connectors in printed circuits and wiring boards for high technology applications. The Company competes by adapting certain technologies to meet specific product applications, aiming to produce connectors cost-effectively, and through its production capabilities. In addition, there are many companies who offer connectors with designs similar to those utilized by the Company and are direct competitors of the Company.

The primary basis upon which the Company competes is product performance and production capabilities. The Company usually receives job orders after submitting bids pursuant to customer-issued specifications for connectors and interconnects. The Company’s bid can be for a new item that requires the item to perform under harsh environment requirements or it can be for a standard catalog item. The Company also offers engineering services to its customers in designing and developing connectors for specialized products and specific customer applications. This enables the Company to receive a competitive advantage over those companies who basically manufacture connectors based solely or primarily on catalog specifications.

Some of the Company’s competitors may have greater financial resources than the Company and no assurances can be given that the Company will be able to compete effectively with these companies in the future.

Suppliers of Raw Materials and Component Parts:

The Company utilizes a variety of raw materials and manufactured component parts, which it purchases from various suppliers. These materials and components are available from numerous sources and the Company does not believe that it will have a problem obtaining such materials and parts in the future, both locally or globally.

However, any delay in the Company’s ability to obtain necessary raw materials and component parts may affect its ability to meet customer production needs. In anticipation of such delays, the Company carries an inventory of raw materials and component parts to avoid shortages and to ensure continued production. However, as global supply chains continue to be constrained and impacted, by geopolitical and economic conditions, there can be no assurance that we will not be affected in the future, and we believe that raw materials and supply chains may continue to be affected in fiscal year 2027 and beyond in part due to global uncertainty.

Additionally, continuing inflationary pressures have been impacting virtually all aspects of our materials and suppliers, including power prices and labor costs, and are likely to impact our fiscal year 2027 results.

Human Capital Management:

Our employees are our greatest resource and an integral component to our operations. Their health, safety and well-being are a priority for us.

Talent

We are focused on sourcing, attracting, and retaining talent, especially those with technical backgrounds. We recognize and reward performance while continually working to develop, engage and retain high-performing employees. We have made significant investments to provide ongoing training and career development for our employees. We provide competitive compensation and comprehensive benefits.

As of March 31, 2026, we employed 176 people of which 174 are full-time employees. Around half of the employees engaged in manufacturing and testing activities are covered by a collective bargaining agreement with the United Auto Workers of America, Local 259 (the “Union”), which expires on March 31, 2027.

Safety/Health and Wellness

We are committed to providing a safe and healthy work environment for our employees. Aligned with our values, we strive to continuously monitor our work environment to keep our employees safe. We have an open-door policy for all employees to report concerns or safety issues. Our commitment to employee safety also includes ongoing safety communications with safety topics and providing safety training.

Governmental Regulations:

The Company is subject to federal regulations, principally under the Occupational Safety and Health Act (“OSHA”), Defense Supply Command Columbus (“DSCC”) and the Defense Logistics Agency (“DLA”).

OSHA provides federal guidelines and specifications to companies in order to insure the health and safety of employees.

DSCC oversees the quality and specifications of products and components manufactured and sold to the government and the defense industry. DSCC’s primary customer is the U.S. military. Many of our products appear on DLA Qualified Products Listing (“QPL”). To remain qualified, the Company submits its products to an outside testing laboratory approved by DLA which performs all required testing. After review by the Company of the testing results, the data is then submitted to DLA. The Company and its products are only approved and remain on the QPL if the Company has passed all testing requirements. Although DLA continuously requires suppliers to meet changing specifications, the Company has not encountered any significant problems meeting such specifications and its products have, in the past, been approved. The Company is unaware of any changes in the governmental regulations which are expected to materially affect the Company’s business.

The Company is also subject to various laws and governmental regulations concerning environmental matters. Compliance with these federal, state, and local laws and regulations related to protection of the environment has had no material effect on our business.
