Reports Results for the Fiscal Third Quarter Ended June 24, 2006

CONCORD, MA, July 28, 2006 – Technical Communications Corporation (OTCBB: TCCO.OB) today announced its results for its fiscal third quarter. For the quarter ended June 24, 2006, the Company reported net income of $114,000, or $0.08 per share, on revenue of $1,133,000, as compared to a net loss of $60,000, or $(0.04) per share, on revenue of $751,000 for the same period in fiscal 2005. For the nine months ended June 24, 2006, the Company reported a net loss of $149,000, or $(0.11) per share, on revenue of $3,052,000, as compared to a net loss of $379,000 or $(0.28) per share, on revenue of $2,493,000 for the same period in fiscal 2005.

Commenting on corporate performance, Mr. Carl H. Guild, Jr., President and Chief Executive Officer of TCC said, “TCC’s performance in the third quarter continues to show steady improvement with a 13% increase in revenues when compared to the previous quarter. Although revenues are up, we still maintain a cautiously optimistic view of revenue growth, as foreign national budgets are unpredictable and are experiencing procurement delays in the areas into which we sell. During the third quarter, the company did achieve profitability while maintaining a strong investment in internal product development – a critical balance we believe fuels the development of new products, market initiatives and, ultimately, revenue.

We have actively pursued expansion of our secure telephony product line which features the CSD3324SE Secure Telephone. During the quarter, TCC completed deliveries to an Asian customer under a contract valued at more than $730,000. This delivery will complete another phase of this customer’s national government deployment. In addition, improved features are under development as requested by this customer. These features and improvements will be available in future versions of the CSD3324SE and via an upgrade program to existing deployed equipment. In another Asian country, TCC is competing for a large national secure telephone system that is expected to begin initial deployment in 2007. This program could potentially require approximately 1700 secure telephones for the full national deployment.”
