Reports Results for the Fiscal Fourth Quarter and Year Ended September 30, 2006

CONCORD, MA, November 21, 2006– Technical Communications Corporation (OTC BB: TCCO.OB) today announced its results for the fiscal quarter and year ended September 30, 2006. For the quarter ended September 30, 2006, the Company reported net income of $54,000, or $0.04 per share, on revenue of $845,000, as compared to net income of $349,000, or $0.26 per share, on revenue of $1,228,000 for the same period in fiscal 2005. For the year ended September 30, 2006, the Company reported revenue of $3,897,000 and a net loss of $94,000, or $0.07 per share, as compared to revenue of $3,721,000 and a net loss of $30,000, or $0.02 per share, for fiscal 2005.

Commenting on corporate performance, Mr. Carl H. Guild, Jr., President and Chief Executive Officer of TCC said, “Revenues for the fourth quarter were below our expectations due to the delay in certain foreign procurements. However, profitability was achieved as the mix of the delivered products reflected higher gross margins when compared to those of the previous quarter. The delayed procurements, which are for encryption devices for military bulk data networks and the HF/VHF radio products, are expected to proceed in 2007. These projects are part of our broader effort to expand our installed equipment base, and to develop new users of TCC encryption products.

During the quarter, TCC delivered additional bulk encryption equipment for the ship-to-ship communication requirements of a foreign navy, secure telephones for the expansion of a network in South America, and over 250 radio encryption units for the initial deployment of TCC-encrypted military radio equipment in Afghanistan.”

Mr. Guild continued, “As we have mentioned in previous reports, TCC continues to maintain its investment levels in new product development and has announced CipherSMS™, a high security text messaging encryption application for mobile phones using the Windows Mobile 5.0 operating system. We believe CipherSMS™ works as easily as conventional Short Messaging Service (SMS) but provides robust end-to-end encryption for the user. Worldwide text messages can now be sent with complete security. Additional information on CipherSMS and our other wireless security products is available at our web site, www.tccsecure.com.”
