This press release corrects a press release distributed on May 8, 2023 under the same headline which contained two misstated dates.

San Diego, California – May 8, 2023 – Sonim Technologies, Inc. (Nasdaq: SONM), a leading provider of ultra-rugged, rugged and consumer durable mobile devices including phones, tablets and accessories designed to provide extra protection for users that demand more durability in their work and everyday lives, reported financial results for the first quarter ended March 31, 2023.

First Quarter 2023 and Recent Highlights

Peter Liu, Sonim’s Chief Executive Officer, said: “We are excited to report positive net income on a GAAP basis, a capstone achievement just 8 months following the new management team’s appointment in July 2022. We reported 95% year-over-year revenue growth in the first quarter, confirming the success of our refreshed core business in rugged mobile devices available at Tier-1 carriers in North America and our strategy to expand into large, profitable adjacent markets.

“The first quarter results signal completion of the first phase our strategy, achieving both growth and profitability through a diversified, sustainable rugged mobility and ODM devices business. We are now moving into the second phase of our growth strategy at Sonim, targeting continued revenue growth rates of 50% or more annually for the next three years. In order to achieve this goal, we intend to sustain and grow our core rugged mobile devices business, as well as leverage our rugged expertise to expand into exciting enterprise data and consumer durable device opportunities, tapping a larger addressable market estimated at more than $70 billion in size.”

First Quarter 2023 Financial Results

Revenue for the first quarter 2023 was $25.8 million, increased 7% from $24.1 million in the fourth quarter 2022 and increased 95% from $13.3 million in the first quarter 2022. Revenue reflected the launch of Sonim’s new fully refreshed rugged mobile device line, including the XP10 Android smartphone, XP5plus and XP3plus devices, plus continued fulfillment of Android tablet customer purchases exemplifying Sonim’s new capabilities to win business in large adjacent markets leveraging its rugged heritage and ODM relationship capabilities.

Gross profit for the quarter ended March 31, 2022, was $4.2 million, or 16% of revenues, compared with fourth quarter 2022 gross profit of $3.9 million, or 16% of revenues, and $1.5 million, or 12% of revenues in the prior year quarter. The increase in gross profit margin was attributable to product sales mix, including increased sales of the newly refreshed rugged products line, offset by lower margin but higher volume non-Sonim branded ODM tablet shipments. Increased sales of Sonim’s updated rugged cell phones, including the updated XP10 rugged smartphone, are expected to increase unit sales of Sonim’s higher margin devices in 2023.

Operating expenses for the first quarter 2023 were $3.8 million, compared to $5.0 million in the fourth quarter 2022, and declining from $8.6 million in the 2022 first quarter. Operating expenses were lower due to lower R&D and legal expenses. Net profit in the first quarter was $227 thousand, compared with net loss of $1.0 million in the fourth quarter 2022 and net loss of $7.2 million in the prior year quarter.

“We are excited to achieve positive net income on a GAAP basis, reflecting both strong revenue growth over the past year as well as diligent expense control through our operating cost light business model.,” said Clay Crolius, Chief Financial Officer. “We will now focus on further scaling sales and operating metrics while expanding our addressable markets with new devices that build upon our unparalleled rugged products heritage. Our balance sheet is well funded to support these goals as we continue to fund our working capital needs and grow the business.”

Additionally, in May 2023 the Company was notified that it had regained compliance with the Nasdaq minimum bid price rule for continued listing on the Nasdaq Stock Exchange. in March 2023 Sonim was informed that the Securities and Exchange Commission concluded its investigation without enforcement action. Conclusion of the matter is further expected to reduce operating costs through the savings in legal expenses, which amounted to $1.1 million in 2022.

Balance Sheet and Working Capital

Sonim ended the first quarter with $9.0 million in cash and equivalents and remained essentially debt free. Accounts receivable increased sequentially to $25.0 million on increased sales, and inventory increased to $4.5 million.
