Technical Communications Corporation Announces Decision to Go “Dark”

CONCORD, Mass., Sept. 25, 2023 (GLOBE NEWSWIRE) -- Technical Communications Corporation (OTCQB: TCCO) today announced its decision to deregister its common stock under Section. 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as suspend its reporting obligations under Section 15(d) of the Exchange Act.

This decision to go “Dark” is in support of the Company’s intention to return to profitability as soon as possible and using cash resources for that purpose is the top fiscal priority. The reduction in time spent by its management and employees in complying with the requirements applicable to SEC reporting companies will enable them to focus our resources more on managing the Company’s business and generating new revenues.

The Company filed a Form 15 with the Securities and Exchange Commission on September 21, 2023 to deregister its securities under Section 12(g) of the Exchange Act and suspend its reporting obligations under Section 15(d) of the Exchange Act. The Company will communicate other news and information to shareholders from time to time via its website www.tccsecure.com .
