For the quarter ended September 30, 2017, the Company reported a net loss of $(518,000), or $(0.28) per share, on revenue of $1,125,000, compared to a net loss of $(860,000), or $(0.47) per share, on revenue of $405,000 for the quarter ended October 1, 2016.

Commenting on corporate performance, Carl H. Guild, Jr., President and Chief Executive Officer of TCC, said, "TCC revenues were lower than anticipated due to delays on key international programs. Our radio encryption product line has contributed significantly to our 2017 sales with completion of an order from Datron that is destined for use in Afghanistan. We expect that additional orders will be coming in support of continuing U.S. government activities in Afghanistan but the timing is unpredictable.

TCC continues to pursue the application of our radio encryption products to new customers requiring voice communications security for joint air, land and sea operations. Our new HSE6000 SEAL radio encryption system has successfully completed customer reviews and is participating in field operational testing.

Network encryption solutions are being pursued with the development of a TCC proprietary platform that can be customized to meet unique customer requirements. This work is still in the development phase but is expected to reach the market in late 2018.

TCC is committed to returning to profitability in fiscal 2018. We continue to closely monitor and reduce operating expenses as appropriate, while strategically investing in business development efforts, developing productive relationships and expanding our sales channel network."
