Giga-tronics Announces Preliminary Results for the Second Quarter FY 2016

San Ramon, CA – October 26, 2015 – Giga-tronics Incorporated (Nasdaq: GIGA) announced today preliminary results for the second quarter of fiscal 2016. Net sales for the second quarter are expected to be in the range of $2.9 million to $3.1 million, compared to quarterly net sales ranging from $4.3 million to $5.1 million over the past four quarters. Net loss for the second quarter is expected to be between $1.0 million to $1.4 million.

These preliminary, unaudited financial results are based on management’s initial review of operations for the quarter ended September 26, 2015, and remain subject to change based on management’s ongoing review of the second quarter results.

Mr. John Regazzi, the Company's CEO stated, “In the second quarter we experienced delays in shipments due to late arriving materials from our suppliers and technical issues associated with the new Advanced Signal Generator. Many of the delayed second quarter shipments have been delivered to customers this month, including multiple units of the Advanced Signal Generator. Our second quarter ending backlog remained substantial at $15.8 million, of which $6.5 million is shippable within a year. We will provide more details on our upcoming regular quarterly results conference call.”

Giga-tronics also announced today a lapse in AS9100C certification of its Supplier Quality Management System. Certification did not impact sales in the second quarter of fiscal 2016, but could impact future orders and shipments if the Company does not regain AS9100C certification or reach other satisfactory arrangements with those customers requiring such certification.

Mr. Regazzi concluded, “We are working diligently to regain AS9100C compliance. Not all orders and shipments require AS9100C certification, and when required we are working with customers on other measures that can be taken to support shipments during this lapse.”
