"We achieved an important milestone in the fourth quarter of fiscal 2015 when after years in development, two customers accepted their initial units of our Advanced Signal Generation System," CEO JohnRegazzi said in a statement.

TheStreet Ratings team rates GIGA-TRONICS INC as a Sell with a ratings score of D-. TheStreet Ratings Team has this to say about their recommendation:

"We rate GIGA-TRONICS INC (GIGA) a SELL. This is driven by a number of negative factors, which we believe should have a greater impact than any strengths, and could make it more difficult for investors to achieve positive results compared to most of the stocks we cover. The company's weaknesses can be seen in multiple areas, such as its generally high debt management risk and weak operating cash flow."
