About SONO TEK CORP

Sono-Tek Corp. (ticker: SOTK) is a U.S.-listed company traded on the Nasdaq market in the United States. The company was incorporated in New York in 1975 and is headquartered at Sono-Tek Industrial Park in Milton, New York. It is a relatively small-cap industrial technology company with roughly 90–93 employees in its recent corporate materials, and it reaches customers through direct sales, selected independent distributors, and sales representatives across a worldwide network. ([sono-tek.com](https://www.sono-tek.com/about-us/investors/)) Sono-Tek’s core business is the design and manufacture of ultrasonic coating systems. These systems are used to apply thin films and precision coatings to parts where performance and consistency matter. The company’s product set includes multi-axis coating systems, integrated coating systems, fluxing systems, OEM systems, and related platforms, alongside application consulting services. This combination positions Sono-Tek as a solutions provider rather than a simple equipment vendor. Its technologies are deployed in medical devices, semiconductors, microelectronics, alternative energy, advanced industrial manufacturing, and research applications. ([sono-tek.com](https://www.sono-tek.com/about-us/investors/)) From a competitive standpoint, Sono-Tek operates in a niche market focused on high-precision liquid atomization and thin-film deposition. Its value proposition lies in process control, repeatability, and the ability to scale from R&D tools into higher-ASP production equipment. Management has emphasized that the product mix is gradually shifting toward production systems, which is important for long-term revenue quality. The company has particularly strong exposure to medical device manufacturing, where its equipment is used for coating stents, balloons, diagnostic devices, and drug-delivery platforms. It also serves electronics-related applications and clean-energy coating use cases such as fuel cells, carbon capture, and advanced solar cells. ([sono-tek.com](https://www.sono-tek.com/about-us/investors/)) Geographically, Sono-Tek remains anchored in the United States but has built a meaningful international footprint. The company states that it sells worldwide, and its fiscal 2025 materials indicate that about 39% of sales came from outside the United States and Canada. That level of non-domestic exposure suggests a business model that is increasingly diversified beyond its home market. ([sono-tek.com](https://www.sono-tek.com/wp-content/uploads/2025/06/Corporate-Governance-2025.2.pdf)) Recent developments have been supportive of the investment case. In October 2025, Sono-Tek announced a purchase order worth more than $2.8 million from a major U.S. medical device manufacturer, highlighting repeat demand from an existing customer and continued traction in a strategic end market. In January 2026, the company also reported that shipments of high-ASP in-line coating systems to a major solar energy customer helped drive strong growth in that product line. Separately, Sono-Tek promoted Chris Cichetti to Chief Operating Officer in March 2025, reflecting ongoing management succession and operating execution. For French-speaking investors, SOTK offers a focused U.S. Nasdaq technology story with niche market leadership, a broad end-market spread, and growing international relevance.
