Reports Results for Third Fiscal Quarter Ended June 25, 2005

CONCORD, MA, August 10, 2005– Technical Communications Corporation (OTC BB: TCCO.OB) today announced its results for its third quarter of fiscal 2005. The Company reported revenue of $751,000 and a net loss of $60,000, or $(0.04) per share, for the quarter ended June 25, 2005, as compared to revenue of $1,413,000 and net income of $606,000, or $0.45 per share, for the same period in fiscal 2004. For the nine months ended June 25, 2005, the Company reported a net loss of $379,000, or $(0.28) per share, on revenue of $2,493,000, as compared to net income of $962,000, or $0.72 per share, on revenue of $3,573,000 for the same period in fiscal 2004.

Commenting on corporate performance, Mr. Guild said, “Our performance in the third quarter has shown some anticipated improvement although it is not back to profitable levels. We expect this positive trend to continue into the fourth quarter and are hopeful of a return to profitability. As expressed in our last quarter’s release, TCC has several new international requirements for upgraded and expanded secure communications systems which are expected to generate revenue. Orders have been received for the expansion of an airborne secure voice radio system for a government in South America and a satellite based system for a Mideast government using our new CX7200 Multicast Internet encryptor. Acceptance of a major system upgrade by a principal customer in Africa is expected in the fourth quarter and are expected to provide an opportunity for additional sales of systems as well as upgrade kits. During the third quarter, secure telephone systems were sold to a major US defense contractor for international sales operations and a US city government utilizing Homeland Security funding.”

Continuing, Mr. Guild said, “Of significance to our future sales is our activity in Iraq and Afghanistan. TCC has sales initiatives in both countries and TCC radio encryptors have been successfully tested in Iraq and testing is planned for Afghanistan. Equipping the national forces with secure communications is a key element in establishing a capable national security force and TCC’s radio encryptors adapt easily and reliably to a variety of radio systems.”
