Commenting on the Company’s move, Stephen J. Bagley, Chief Financial Officer stated, “We are extremely happy to upgrade to OTCQX U.S. Premier, where our company stock will now be traded. The move to OTCQX is further evidence that Sono-Tek’s sales growth and profitable results are paying off due to the qualification requirements that must be met to trade on OTCQX. In addition, our shareholders and potential shareholders should find it easier to trade and hold our stock through the institutional, retail and online broker of their choice.

The move to OTCQX could not have come at a better time. The company recently announced its goal of growing revenues to $20,000,000 by 2020, based on the creation of a New Product Development Team to augment its current market and product development staffing. It is also seeing the potential for its food industry segment to grow at a faster pace as the industry becomes more sensitive to the consequences of food borne illnesses,” continued Bagley.

“Sono-Tek has been revolutionizing the field of ultrasonic spray systems for 40 years, developing new, environmentally-friendly applications for use in everything from drug eluting cardiac stents and medical devices to printed circuit boards to fuel cells, solar cells, architectural and automotive glass,” said R. Cromwell Coulson, President and CEO of OTC Markets Group. “We are thrilled to welcome Sono-Tek to our family of investor-focused OTCQX companies and look forward to supporting the company in its continued growth.”
