Sonim Reports Second Quarter Results

Focused on Launch of Next Generation Ultra-Rugged Mobile Phone Products

Austin, Texas – August 16, 2021 – Sonim Technologies, Inc. (Nasdaq: SONM), a leading U.S. provider of ultra-rugged mobile devices, accessories and solutions designed specifically for task workers physically engaged in their work environments, reported financial results for the second quarter ended June 30, 2021.

Second Quarter 2021 and Recent Highlights

Said Bob Tirva, President and Chief Operating Officer: “Sonim has made significant progress preparing for the third-quarter launch of the first of our next-generation devices, an enhanced version of our highest volume feature phone. We expect this launch to be the start of a series of planned launches of products over the coming quarters, including the fulfillment of the two design awards at a major US carrier that we previously announced. We are optimistic that the new infrastructure bill will be potentially beneficial to Sonim and the market for ruggedized phones will expand. We think that the recent design wins are potentially indicative of this emerging trend.

“We also posted improved sequential operating results in the second quarter, including increased gross profit and reduced operating expenses, as the result of prudent expense management by our employees and a reduction of legal expenses. We continue to find ways to operate efficiently as we expand our product line with additional product launches scheduled for 2022.”

First Quarter 2021 Financial Results

Net revenues for the second quarter of 2021 were $12.0 million, compared with $12.2 million in the first quarter of 2021 and $21.1 million in the second quarter of 2020. The change in net revenue reflected the expected decline in sales of legacy products.

Gross profit for the second quarter of 2021 increased 8% sequentially to $2.7 million (22.2% of net revenues) from $2.5 million (20.1% of net revenues) in the first quarter of 2021, and declined 46% from $4.9 million in the second quarter of 2020.

Operating expenses for the second quarter declined to $9.1 million, compared with $11.5 million in the first quarter 2021 and $11.5 million in the prior year quarter. Net loss for the second quarter of 2021 improved to $6.7 million, or ($0.10) per basic and diluted shares, compared with net loss of $9.3 million or $(0.14) per basic and diluted share in the first quarter of 2021 and compared to net loss of $7.1 million in the second quarter of 2020, or $(0.22) per basic and diluted share.

Balance Sheet and Cash Flow

Sonim ended the quarter with $6.9 million in cash and equivalents and remained essentially debt free. Subsequent to the quarter end, Sonim raised an additional $8.4 million in net proceeds through its at-the-market equity offering program during July 2021. Inventory was $11.9 million at quarter end, and accounts receivable was $10.5 million.
