Sonim Reports Preliminary Second Quarter 2020 Results

Revenue Increases 65.7% Sequentially to $21.1 Million

Full Results and Call on August 12, 2020

Austin, Texas – July 28, 2020 – Sonim Technologies, Inc. (Nasdaq: SONM), a leading U.S. provider of ultra-rugged mobility solutions designed specifically for task workers physically engaged in their work environments, today announced preliminary results for the second quarter ended June 30, 2020. On a preliminary, unaudited basis, the company expects to report, for the second quarter of 2020, net revenues of $21.1 million, an increase of approximately 66% from $12.7 million in the first quarter of 2020, and gross margin of 23.4%, up from 17.0% in the first quarter of 2020.

“We expect that net revenue increased approximately 66% to $21.1 million in the second quarter as a result of our carrier relationships and increased marketing,” said Tom Wilkinson, Chief Executive Officer. “We also expect that gross margin improved during the quarter, and we continued to deliver cost efficient operations across our entire corporate structure as previously communicated in our turnaround plan for Sonim. As a result of these efforts, we generated positive cash flows in the second quarter.”

“In addition to the strong second quarter operating performance and positive cash flows, we added $27.6 million in gross proceeds from a public offering of our common stock completed in June and subsequently repaid more than $10 million in debt and accrued interest through a combination of cash and equity,” said Wilkinson. “We expect to report that we ended the quarter with cash and cash equivalents of more than $38 million and no debt, providing a strong platform on which to continue investing in both organic and strategic growth ahead.”
