Peter Liu, Sonim's Chief Executive Officer, said: "In 2023, Sonim achieved significant growth with a 34% increase in sales, improvement of the GAAP net loss to $90 thousand, $4.0 million in positive adjusted EBITDA, and three quarters of positive GAAP net income, highlighting the early success of our strategy to grow and diversify. This is only the beginning of what we plan to achieve. We look forward to further growth and scale in 2024, driven by a growing number of new product awards from tier-one carriers, expansion into large adjacent addressable markets, and our entry into Europe and Australia, all fueled by new sales activities.

"The interest from carriers in our new products has been exceptional, with 13 product awards already announced for this year and a strong pipeline of additional opportunities in North America, Europe, and Australia. We believe that the launches for the new portfolio in the year ahead positions Sonim to become the preferred brand for reliable, durable devices in these larger markets.

"Furthermore, with the exit of the previous largest rugged supplier, Europe presents a significant opportunity for Sonim. We are actively working to qualify our newest products to fill this gap, targeting a major market opportunity for Sonim in rugged mobility and connected solutions."

Full Year 2023 Financial Results
Revenue for the full year 2023 was $93.6 million, increased 34% from $69.8 million in 2022. Revenue reflected increased sales of the Company's refreshed ultra-rugged product line at carrier partners in North America and augmented by sales of the Company's ODM tablet products. Sonim also continues to win business in large adjacent markets concurrent with its strategy to bring additional solutions to market and expand its geographic reach to a global scale. To date, Sonim has now secured 13 carrier awards, including international awards, for its expanded range of mobile communication and data devices.

Gross profit for the year ended December 31, 2023, was $19.3 million, or 20.6% of revenues, compared with 2022 gross profit of $11.6 million, or 16.6% of revenues. Gross profit margins reflected a more favorable product mix due to increased sales of the refreshed XP10 rugged smartphone.

Operating expenses for 2023 were $18.8 million, declining from $25.9 million in 2022. This year-over-year decrease in operating expenses is mainly due to reduced R&D spending as the Company moved to more efficient, product development strategies, offset by increases in sales and marketing to support the launch of the Company's new connected solutions and international strategies.

Net loss in 2023 was $90 thousand, compared with a net loss of $14.1 million in 2022. Adjusted EBITDA^† was $4.0 million for the year ended December 31, 2023, compared to negative $9.9 million for the year ended December 31, 2022.

"Sonim delivered three consecutive quarters of positive GAAP net income in 2023, resulting in an improvement to the net loss to $90 thousand, and a solid full year adjusted EBITDA report of $4.0 million. We are well positioned for carrier launches with our new connected devices and rugged mobile lines scheduled throughout 2024. We are now driving sales across multiple large addressable markets in 2024, as compared with just one market in 2023. As part of this expanded strategy, we have also significantly expanded geographic reach, opening new and much larger opportunities for growth in Europe," said Clay Crolius, Chief Financial Officer of Sonim.

Fourth Quarter 2023 Financial Results
Revenue for the fourth quarter 2023 was $13.4 million, decreased from $27.6 million in the third quarter of 2023. Revenue reflected continued sales growth of the Company's differentiated rugged devices offset by the expected decline in sales from the Company's previous tablet customer, which hit end of life. The Company has secured new awards for white label smartphones, with shipments ramping up in the first quarter 2024. Additionally, the Company expects continued revenue growth in 2024 based on its carrier product awards scheduled to commence shipments throughout the year.

Gross profit for the fourth quarter was $5.1 million, or 38.1% of revenues. Operating expenses were $6.4 million, reflecting the addition of sales resources in Europe as part of the Company's global growth strategy. Net loss in the fourth quarter of 2023 was $1.4 million, compared with a net loss of $1.1 million in the fourth quarter of 2022, the Company's first quarterly net loss following three successive quarters of GAAP net income in 2023.

Balance Sheet and Working Capital
Sonim ended 2023 with $9.4 million in cash and equivalents and remained essentially debt free. Accounts receivable was $25.3 million and inventory was $6.5 million. Sonim continues to self-fund its working capital and product development needs out of existing cash.

Non-GAAP Financial Measures

In addition to our financial results determined in accordance with U.S. GAAP, we believe the following non-GAAP and operational measures are useful in evaluating our performance-related metrics and present them as a supplemental measure of our performance.

Adjusted EBITDA

We define Adjusted EBITDA as net loss adjusted to exclude the impact of stock-based compensation expense, depreciation and amortization, interest expense, and income taxes. Adjusted EBITDA is a useful financial metric in assessing our operating performance from period to period by excluding certain items that we believe are not representative of our core business, such as certain material non-cash items and other adjustments, such as stock-based compensation.

We believe that Adjusted EBITDA, viewed in addition to, and not in lieu of, our reported GAAP results, provides useful information to investors regarding our performance and overall results of operations for various reasons, including: non-cash equity grants made to employees at a certain price do not necessarily reflect the performance of our business at such time, and as such, stock-based compensation expense is not a key measure of our operating performance; and non-cash depreciation and amortization are not considered a key measure of our operating performance. We use Adjusted EBITDA: as a measure of operating performance; for planning purposes, including the preparation of budgets and forecasts; to allocate resources to enhance the financial performance of our business; to evaluate the effectiveness of our business strategies; in communications with our board of directors concerning our financial performance; and as a consideration in determining compensation for certain key employees.

Adjusted EBITDA has limitations as analytical tools, and should not be considered in isolation, or as a substitute for analysis of our results as reported under GAAP. Some of these limitations include: it does not reflect all cash expenditures, future requirements for capital expenditures or contractual commitments; it does not reflect changes in, or cash requirements for, working capital needs; it does not reflect interest expense on our debt or the cash requirements necessary to service interest or principal payments; and other companies in our industry may define and/or calculate this metric differently than we do, limiting its usefulness as a comparative measure.

Set forth below is a reconciliation from net loss to Adjusted EBITDA for the respective periods (in thousands):
