Sono-Tek Corporation SOTK

Company Overview

Sono-Tek Corporation is a U.S.-based precision engineering company that develops and manufactures ultrasonic coating systems used to apply thin-film coatings in industrial and advanced manufacturing applications. The company operates primarily within the industrial automation, electronics manufacturing, medical device, clean energy, and advanced materials sectors. Its core technology uses ultrasonic atomization to create highly uniform coatings with reduced material waste compared with conventional spray technologies. Sono-Tek’s systems are used in applications including fuel cells, semiconductors, printed electronics, medical diagnostics, glass coatings, and precision industrial components.

The company generates revenue primarily through the sale of ultrasonic coating equipment, integrated systems, and related services. Its products are marketed to manufacturers, research institutions, and OEM customers seeking precision coating solutions for high-value applications. Sono-Tek was founded in 1975 and is headquartered in Milton, New York. Over time, it evolved from a niche ultrasonic spray technology provider into a supplier serving multiple high-growth technology markets, particularly in clean energy and electronics manufacturing. Public filings and company disclosures consistently identify its proprietary ultrasonic nozzle technology as a key competitive differentiator due to its precision, scalability, and lower material consumption.

Business Operations

Sono-Tek operates largely as a single business focused on the design, manufacture, and sale of ultrasonic spray coating systems and related components. The company’s offerings include integrated coating systems, custom-engineered automation platforms, ultrasonic nozzles, generators, pumps, and application development services. Revenue is derived from direct equipment sales, replacement components, engineering support, and customer-specific system integration projects. Its customer base spans industries requiring controlled deposition of coatings, including electronics, medical diagnostics, alternative energy, and industrial manufacturing.

The company maintains operations in both domestic and international markets, with sales distributed across North America, Europe, and Asia. Sono-Tek’s proprietary ultrasonic atomization technology represents its principal technological asset and is protected through patents, engineering know-how, and application expertise. The company has historically relied on a combination of direct sales personnel, distributors, and regional representatives to support international customers. Public disclosures indicate ongoing collaboration with manufacturers and research organizations involved in hydrogen fuel cells, semiconductor fabrication, and advanced electronics production.

Strategic Position & Investments

Sono-Tek’s strategic direction has centered on expanding its presence in high-growth precision manufacturing markets, particularly clean energy, advanced electronics, and medical technologies. The company has increasingly focused on applications tied to hydrogen fuel cells, solar technologies, semiconductor packaging, and microelectronics, where coating uniformity and material efficiency are critical. Management has consistently identified growth opportunities associated with electrification trends, renewable energy infrastructure, and advanced sensor manufacturing.

Rather than pursuing large-scale acquisitions, Sono-Tek has historically emphasized organic growth through internal research and development, product customization, and expansion of application engineering capabilities. Its investments have included enhancements to automated coating platforms and process technologies intended to support scalable industrial production environments. Publicly available filings and investor communications also indicate continued investment in international sales channels and production capabilities to support demand from electronics and clean energy customers. Data regarding significant acquisition activity or major portfolio holdings is inconclusive based on available public sources.

Geographic Footprint

Sono-Tek is headquartered in Milton, New York, and serves customers across multiple global manufacturing regions. The company maintains a sales presence throughout North America, while also generating revenue from customers in Europe and Asia, particularly in countries with strong electronics and advanced manufacturing sectors. International demand has become increasingly important as semiconductor production, battery technologies, and fuel cell development expand globally.

The company’s systems are used by manufacturers, research institutions, and industrial customers in numerous countries, with international sales supported through distributors and regional representatives. Public disclosures identify China, Japan, South Korea, and parts of Europe as important markets tied to electronics, clean energy, and industrial automation demand. While Sono-Tek remains comparatively small relative to major industrial equipment providers, its specialized coating technologies give it exposure to globally distributed advanced manufacturing supply chains.

Leadership & Governance

Sono-Tek’s leadership team combines engineering, manufacturing, and industrial technology experience, with a strategic focus on precision manufacturing applications and long-term technology development. Governance is overseen by a board of directors and executive leadership team responsible for operational execution, research and development priorities, and international market expansion. Company communications and regulatory filings emphasize innovation, disciplined operational management, and expansion into high-value industrial sectors as central components of corporate strategy.

Key executives include:

• Christopher L. Coccio – President and Chief Executive Officer
• Mary Anne Newman – Chief Financial Officer
• Dr. Stephen Harshbarger – Vice President, Technology
• Brian Booth – Vice President, Sales and Marketing

Public filings, including SEC filings and annual reports, indicate that leadership has prioritized growth in advanced energy, electronics, and medical markets while maintaining a focus on proprietary technology development and manufacturing efficiency. Information regarding founder involvement in current governance is limited in recent public disclosures.
