Item 1. BUSINESS

Sono-Tek Corporation (the “Company”, “Sono-Tek”, “We” or “Our”) is the world leader in the design and manufacture of ultrasonic coating systems for applying precise, thin film coatings to add functional properties, protect or strengthen surfaces on parts and components for the microelectronics/electronics, alternative energy, medical, industrial and emerging research & development/other markets. We design and manufacture custom-engineered ultrasonic coating systems incorporating our patented technology, in combination with strong applications engineering knowledge, to assist our customers in achieving their desired coating solutions.

Our ultrasonic nozzle systems use high frequency ultrasonic vibrations that atomize liquids into minute drops that can be applied to surfaces at low velocity providing microscopic layers of protective and other useful materials over a wide variety of surfaces, including glass and metals. Our equipment solutions are environmentally-friendly, efficient and highly reliable. They enable dramatic reductions in overspray, savings in raw materials, water and energy usage and provide improved process repeatability, transfer efficiency, high uniformity and reduced emissions. We serve a variety of industries and applications and have a broad base of customers.

The applications that are employing our unique coating technology and expertise have been expanding as the advantages of ultrasonic coatings are more broadly recognized. The original application of our technology was to coat the inner surface of blood collection tubes used for medical diagnostic testing. Our products enable the application of a thin and uniform coating of material that prevents coagulation of blood. Following that initial breakthrough, our technology was then used for applying uniform flux coatings to printed circuit boards, a critical part of the fabrication process for all electronic devices. A later application for much larger surfaces was to address the many challenges that glass manufacturers faced. They needed a solution for specialized glass applications in the construction and automotive industries. Among other things, our ultrasonic nozzles are used to provide coatings that improve durability, create filters, increase clarity, reduce reflection, enable conductivity, and enhance safety. We have invested significant resources to enhance our market diversity by leveraging our core ultrasonic coating technology. As a result, we have increased our portfolio of products, the industries we serve, and the countries in which we sell our products.

We were founded by the inventor of the ultrasonic nozzle, Dr. Harvey Berger, and incorporated in New York on March 21, 1975. We became a public company in 1987 and our stock is traded on the Nasdaq Capital Market. Our corporate offices are located in Milton, New York where our production facilities are co-located. We also have a sales and service office in Singapore and an application process development laboratory in Guangzhou, China. We are ISO 9001 qualified since registering in September 1998 and have been recertified annually since then.

Our fiscal year ends on February 28, except in leap years when it ends on February 29. We refer to the fiscal year ended February 28, 2025 as “fiscal 2025” and use similar protocol for previous fiscal years.
