Technical Communications Corporation Reports Death of Director and Audit Committee Member

Technical Communications Corporation (NasdaqCM:TCCO) today announced the unfortunate passing of long time director and member of its Audit Committee, Mitchell B. Briskin. Mr. Briskin has been a valued member of the Company since 1998, and will be remembered for the many significant contributions he has made to the Company over the past 20 years.

In conjunction with the passing of Mr. Briskin, the Company notified The NASDAQ Stock Market on May 29, 2018 that it was no longer in compliance with Rule 5605(c)(2). This rule requires the Company to maintain an audit committee comprised of at least three directors, all of whom must be independent pursuant to the rules of the NASDAQ Stock Market and applicable law. On May 29, 2018, Nasdaq notified the Company that it has been provided a cure period in order to regain compliance until the earlier of the Company’s next annual shareholders’ meeting or May 27, 2019. The Board of Directors expects to begin a search shortly for a new independent director and audit committee member and expects to be in compliance with Nasdaq Rule 5605(c)(2) prior to the expiration of the cure period.
