On January 14, 2021, Technical Communications Corporation (the “Company”) received a delisting determination letter from the Listing Qualifications department of the Nasdaq Stock Market (“Nasdaq”), notifying the Company that because the Company had informed Nasdaq it would be unable to provide a plan to regain compliance with Listing Rule 5550(b) (the “Rule”) within the required timeframe, trading of the Company’s common stock will be suspended at the opening of business on January 25, 2021. Nasdaq also indicated it will file a Form 25-NSE with the Securities and Exchange Commission, which will remove the Company’s securities from listing and registration on the exchange.

Previously on December 31, 2020, the Company received notice from Nasdaq that because the Company failed to maintain a minimum of $500,000 in net income from continuing operations in the most recently completed fiscal year, or two of the last three fiscal years, and since the Company did not meet the alternatives of market value of listed securities or stockholders’ equity, the Company no longer complied with Listing Rule 5550(b) for continued listing. The Company subsequently determined it would be unable to regain compliance with the Rule within the specified timeframe and informed Nasdaq on January 13, 2021 that it would not be submitting a compliance plan.
