Giga-tronics Reports Results for Q4 FY 2020 and FY 2020

Dublin, CA – May 28, 2020 – Giga-tronics Incorporated (OTCQB: GIGA) (the “Company”) reported results for the fourth quarter and fiscal year ended March 28, 2020.

Revenue for the fourth fiscal quarter ended March 28, 2020 was $2.6 million, as compared to $3.5 million for the same period of fiscal 2019. Fourth quarter revenue was adversely impacted by the Company’s compliance with California’s Shelter-in-Place order during the month of March, which resulted in the temporary closure of its California facilities and a loss of production. Net loss attributable to common shareholders for the fourth quarter was $664,000, or ($0.54) per share, compared to net income of $43,000 or $0.03 per fully diluted share, for the same period last year. The Company recorded an EBITDA loss of ($446,000) for the fourth quarter compared to EBITDA of $392,000 for the same quarter in fiscal 2019. Both the fourth quarter net loss attributable to common shareholders and the EBITDA loss were caused primarily by the sudden shelter-in-place order in March 2020, resulting in a loss of production and associated revenue as well as lower gross profits related the RADAR filter business.

Revenue for the year ended March 28, 2020 was $11.8 million, an increase of 6% compared to $11.1 million for the year ended March 30, 2019. The increase was attributable to a 66% revenue growth of $1.5 million for the Giga-tronics RADAR/EW testing division associated with multiple orders from the US Navy, which was offset by a $1 million or 10% decrease in Microsource filter revenue mainly due to the fourth quarter shutdown described above. Net loss attributable to common shareholders for full year fiscal 2020 was $2.0 million, or ($1.64) per share, compared to a loss of $1.0 million or ($1.45) per fully diluted share, for the same period last year. Net loss in fiscal 2020 includes a one-time, non-cash expense of $1.2 million or ($1.01) per fully diluted share related to the issuance of common shares in exchange for the majority of the Company’s Series E preferred shares on November 8, 2019. EBITDA was $183,000 in fiscal 2020 compared to $362,000 for fiscal 2019. Both the fiscal 2020 net loss attributable to common shareholders and EBITDA were adversely impacted by the temporary fourth quarter closure described above.

Subsequent to the end of its fiscal year, the Company received a $786,200 SBA loan under the Paycheck Protection Program (“PPP”), established as part of the Coronavirus Aid, Relief and Economic Security Act. This PPP funding accrues interest at a rate of 1% per annum and, based on the Company's current operating plan, the Company believes that the majority or all of the principal amount of the loan may be forgiven, provided that it uses the funding proceeds for eligible payroll costs, utility expenses, and rent payments in accordance with the PPP program, in each case during the eight-week period after entering into the loan.

John Regazzi, CEO of the Company said, “Giga-tronics, like many other companies in the U.S., was impacted by the mandated shutdowns in March associated with the COVID-19 pandemic, and as a result of the temporary closure of our California facilities, our fourth quarter revenue, cash flow and profitability were lower than we anticipated. Our shutdown in March was relatively short and we were subsequently designated an essential business. That said, we had also temporarily halted production earlier in the quarter to execute a carefully planned cybersecurity upgrade required by a customer and had expected to shift and complete this production volume during March when the California shutdown unexpectedly occurred. The Company resumed full production levels in April while implementing social distancing measures via two production shifts, remote work-at-home arrangements for most other employees and other appropriate employee safety measures.”

Lutz Henckels, Executive Vice President and Chief Financial Officer, stated, “We continue to manage through the dynamic and uncertain COVID-19 situation, focusing first and foremost on the safety of our employees, while also addressing supply disruptions, and any delays in orders. With our Microsource filter business back in production and the strong interest we are seeing in our higher margin RADAR/EW testing solutions, we are cautiously optimistic about our prospects moving forward.”

Lutz Henckels continued “The RADAR/EW testing solutions business revenues grew 66% in fiscal 2020 and we believe we can drive robust growth in this part of our business in fiscal 2021. We believe national defense RADAR/EW testing represents an addressable market of up to $440 million per year and we are focused on continuing to leverage our proven technology to expand existing and to develop new customer relationships and increase our market share.”
