1. DESCRIPTION OF THE COMPANY

Richardson Electronics, Ltd. is a leading global manufacturer of engineered solutions, power grid and microwave tubes, and related consumables; power conversion and RF and microwave components; high-value replacement parts, tubes, and service training for diagnostic imaging equipment; and customized display solutions. More than 60% of our products are manufactured in LaFox, Illinois, Marlborough, Massachusetts, or Donaueschingen, Germany, or by one of our manufacturing partners throughout the world. All our partners manufacture to our strict specifications and per our supplier code of conduct. We serve customers in the alternative energy, healthcare, aviation, broadcast, communications, industrial, marine, medical, military, scientific, and semiconductor markets. The Company’s strategy is to provide specialized technical expertise and “engineered solutions” based on our core engineering and manufacturing capabilities. The Company provides solutions and adds value through design-in support, systems integration, prototype design and manufacturing, testing, logistics, and aftermarket technical service and repair through its global infrastructure.

Our products include electron tubes and related components, microwave generators, subsystems used in semiconductor manufacturing and visual technology solutions. These products are used to control, switch or amplify electrical power signals, or are used as display devices in a variety of industrial, commercial, medical and communication applications.

We have three operating and reportable segments. Starting with our first quarter earnings release in October for fiscal 2023, we will introduce our new Green Energy Solutions (“GES”) segment. This segment is carved out of our existing PMT segment as we continue to focus on power management applications that support the green energy market globally. Accordingly, in the first quarter of fiscal 2023, we will begin reporting on four segments.

The three operating and reportable segments for fiscal 2022, fiscal 2021 and fiscal 2020 are defined as follows:

Power and Microwave Technologies (“PMT”) combines our core engineered solutions capabilities, power grid and microwave tube business with new disruptive RF, Wireless and Power technologies.

PMT’s focus is on products for power, RF and microwave applications for customers in 5G, alternative energy, aviation, broadcast, communications, industrial, marine, medical, military, scientific and semiconductor markets. PMT focuses on various applications including broadcast transmission, CO2 laser cutting, diagnostic imaging, dielectric and induction heating, high energy transfer, high voltage switching, plasma, power conversion, radar and radiation oncology. PMT also offers its customers technical services for both microwave and industrial equipment.
