Sono-Tek Holds Annual Shareholders Meeting

Milton, NY, August 23, 2013 - Sono-Tek Corporation (OTCQB: SOTK) held its Annual Shareholders Meeting on August 22, 2013 in Milton, New York. The results of Fiscal Year 2013, which ended on February 28, 2013, were discussed.

During the meeting, Dr. Christopher L. Coccio, Chairman and CEO, highlighted the past year’s business performance and future prospects. He noted that while Sono-Tek’s sales decreased last year as a result of declining financial support of clean energy initiatives by governments around the world, the Company implemented cost reduction actions and remained profitable while increasing cash and marketable securities. He also noted that the Company’s sales levels over the previous three years, increased by a rate of over 20% on an annual aggregate growth basis, and that the Company has set a target of returning to double digit revenue growth this year with increased income and cash generation. He noted that the Company created a number of new products aimed at additional markets during last year, and the Company is already seeing a positive impact in sales to the medical device, semiconductor, and food markets.

The Company’s President, R. Stephen Harshbarger, and other members of the management team presented information on the Company’s markets which include electronics, clean energy including fuel cells and solar energy, medical device coatings, and the glass, textile, and food industries.

Since the meeting takes place just prior to the end of the second quarter of the Company’s current fiscal year, Dr. Coccio indicated that “We have seen an increase in sales from the fourth quarter of last year to the first quarter of this year of over 10%, and we expect to show another increase in the current quarter which ends August 31, 2013, supporting our growth targets for this year”.
