Sonim Reports 34% Revenue Increase to $27.6 Million, Continued GAAP Profitability in Third Quarter 2023

Increased Gross Margin, Continued GAAP Net Income Demonstrate Durability of Sonim Financial Model

Growing List of New Tier-One Carrier Design Awards for Sonim Connect and Mobile Phone Devices

San Diego, California – November 14, 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 third quarter ended September 30, 2023.

Third Quarter 2023 and Recent Highlights

Peter Liu, Sonim’s Chief Executive Officer, said: “In the third quarter, we continued to deliver solid performance achieving both sustained revenue growth and GAAP EPS profitability. This success is further validated by new carrier awards ranged for 2024, affirming our plan to enter large new markets and propel future growth with top carriers in North America and internationally. Our strategic commitment to shifting Sonim’s product mix has also improved margins, driving key operating metrics and potentially further increasing profitability.”

“We are excited to expand our carrier award base with a growing roster of wins for our new products that will help us to enter an underserved consumer mobile device market estimated a $70 billion. Our recent awards encompass both our new Sonim Connect data devices portfolio and our new consumer-focused Android phone line for those seeking value, performance and durability in their mobile devices. We are making rapid progress towards solidifying Sonim’s reputation as a renowned brand for specialized devices and durable smartphones in the broader value-conscious market.”

Third Quarter 2023 Financial Results

Revenue for the third quarter 2023 was $27.6 million, increased 34% from $20.5 million in the third quarter 2022 and increased from $26.8 million in the second quarter 2023. Revenue reflected increased sales of the Company’s XP10 smartphone at a growing list of carrier partners in North America and continued sales of the Company’s tablet products. Sonim expects sales of its smartphones to further increase as it expands sales at additional top carrier partners. Sonim also continues to win business in large adjacent markets leveraging its rugged heritage and ODM relationship capabilities, in particular with its newly announced line of wireless connectivity products.

Gross profit for the quarter ended September 30, 2023, was $5.6 million, or 20.3% of revenues, compared with third quarter 2022 gross profit of $3.3 million, or 16.2% of revenues, and $4.4 million, or 16.5% of revenues in the preceding quarter. Gross profit margins reflected a more favorable product mix due to increased sales of the newly refreshed rugged products line, and in particular the Company’s smartphone devices. Increased sales of Sonim’s updated rugged cell phones, including the updated XP10 rugged smartphone, are projected to increase unit sales of Sonim’s higher margin devices in the fourth quarter of 2023.

Operating expenses for the third quarter 2023 were $4.9 million, declining from $5.2 million in the third quarter 2022, and compared with $3.8 million in the 2023 second quarter. This year-over-year decrease in operating expenses is mainly due to reduced R&D spending, while the quarter-over-quarter increase is attributed to renewed R&D activity and higher Sales & Marketing costs associated with new products that will be launched in 2024.

Net profit in the third quarter was $527 thousand, compared with a net loss of $1.6 million in the third quarter 2022 and a net profit of $509 thousand in the second quarter 2023.

“With our third quarter of positive GAAP net income, Sonim has demonstrated the durability of its financial model as we are steadily advancing into additional large adjacent markets that can offer promising growth and margin opportunities from new differentiated solutions sold in conjunction with top carriers in North America and abroad,” said Clay Crolius, Chief Financial Officer of Sonim. “Our strong balance sheet enables us to self-fund both new product development and working capital needs as we pursue growth. This was once again demonstrated in our most recent financial results.”

Balance Sheet and Working Capital

Sonim ended the third quarter with $9.8 million in cash and equivalents and remained essentially debt free. Accounts receivable increased sequentially to $30.3 million on the continued increase in sales, and inventory decreased to $4.2 million. The Company continues to self-fund its working capital and product development needs out of existing cash and cash flows.
