MILTON, N.Y., March 11, 2026 (GLOBE NEWSWIRE) -- 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 $820,000 for coating equipment to be used in the production of diagnostic medical devices.

The order, placed through a subcontractor integrating Sono-Tek’s technology into a larger automated manufacturing line, reflects the continued scaling of production by an existing customer in the medical sector. The system will support a diagnostic-related application involving the deposition of a specialized electronically active layer and represents a significant expansion in production capability compared to earlier equipment supplied by Sono-Tek. The system is expected to ship during fiscal year 2027.

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

“This order reflects the continued progression of our relationship with this customer as they scale their manufacturing capabilities. The customer previously purchased two Sono-Tek production systems priced between $175,000 and $190,000 as they began scaling early production. This latest order represents a meaningful step forward in both system capability and throughput, and demonstrates our strategy of supporting customers as they transition toward larger, more complex production platforms with higher average selling prices.”

This award further reinforces Sono-Tek’s continued success in the medical device sector, a key growth driver in the Company’s long-term strategy. Importantly, this order is from a different customer than the previously announced $5.0 million and $2.8 million medical device system orders, highlighting the Company’s expanding footprint across multiple production programs within the broader medical sector. The Company believes this program may lead to additional opportunities with this customer as production continues to expand, including potential future orders for larger integrated coating systems that further increase average selling prices.
