Sono-Tek Wins $2.8 Million Order for Advanced Medical Device Coating Systems

MILTON, N.Y., October 13, 2025 - Sono-Tek Corporation (Nasdaq: SOTK), the leading developer and manufacturer of ultrasonic coating systems, today announced that it has received a purchase order valued at over $2.8 million from a major U.S.based medical device manufacturer.

This order, placed by an existing customer which is ramping up production, includes multiple advanced ExactaCoat MD (Medical Device) systems. The Exacoat MD systems include expanded capabilities compared to Sono-Tek’s previously supplied equipment. These new systems will be installed in addition to the customer's existing Sono-Tek coating equipment, which will remain in production use. Deliveries of the new equipment are expected to begin in the beginning of calendar year 2026 and be completed within the first half of 2026.

Steve Harshbarger, President and CEO of Sono-Tek, commented:

"This award highlights the continued trust leading medical device manufacturers place in Sono-Tek as they scale production of innovative healthcare technologies. The addition of these higher-capability systems, complementing the Sono-Tek equipment already in use at this facility, underscores the value of our long-term customer relationships and the scalability of our coating platforms. Importantly, this order comes from a different customer than the $5 million medical device order we announced last month, further broadening our base of high-value opportunities."

This win reinforces Sono-Tek's strong position in the medical device sector, a critical growth driver in the Company's long-term strategy, and underscores its ability to capture repeat, multi-million-dollar orders from multiple leading manufacturers across the industry.
