Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

On December 28, 2016, Jan Loeb tendered his resignation as a director of Gyrotron Technology, Inc. (the “Company”) due to other business obligations which Mr. Loeb believes do not allow him to devote proper time to the Company. The following is the text of Mr. Loeb’s e-mail to the Company:

To the Board of Gyrotron,

My recent election to the Board of Keweenaw Land Association and becoming the Chairman of their Strategic Review Committee and my position as CEO of Acorn Energy unfortunately does not allow me to devote the proper time to Gyrotron. Consequently, I hereby submit my resignation to the Board of Gyrotron. My view of the company, its outstanding management and technology has not changed and as a continuing shareholder I will be watching closely as the company’s technology becomes widely adopted. Wishing you all the best.

Very Sincerely,

Jan

Mr. Loeb’s resignation was not due to any disagreements between Mr. Loeb and the Company or disagreements with other officers or directors of the Company regarding its operations, policies or practices.
