SONIM TECHNOLOGIES INC

There are no material changes to the risk factors set forth in Part I, Item 1A,Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023, except as set forth below.

The risk factor titled “Sales of our common stock under the currently effective registration statement or the perception of such sales in the public market or otherwise could cause the market price for our common stock to decline, even if our business is doing well” is amended and restated as follows:

Sales of our common stock under resale registration statements or the perception of such sales in the public market or otherwise could cause the market price for our common stock to decline, even if our business is doing well.

Resales of our common stock may cause the market price of our securities to drop significantly. The sale of shares of our common stock in the public market or otherwise, including sales pursuant to both the effective Form S-3 Registration Statement and Prospectus, dated December 1, 2023, (the “AJP Registration Statement”) and the registration statement and prospectus we are obligated to file pursuant to the Subscription Agreement (the “Liu Registration Statement”) or the perception that such sales could occur, could reduce the prevailing market price of shares of our common stock and increase the volatility of our share price. These sales, or the possibility that these sales may occur, also might make it more difficult for us:

The shares we intend to register for resale through Liu Registration Statement (assuming the exercise of the entirety of the warrants) represent approximately 14% of the outstanding shares of our common stock as of May 3, 2024, and approximately 25% of our public float as of such date. The shares of common stock offered for resale pursuant to the AJP Registration Statement represent approximately 45% of the outstanding shares of our common stock as of May 3, 2024, and approximately 85% of our public float as of such date. Until such time that this registration statement is no longer effective, the registration statement will permit the resale of these shares. As such, sales of a substantial number of shares of our common stock in the public market could occur at any time.

The risk factor titled “In prior years, we identified one material weakness in our internal control over financial reporting which, if not remediated, could have resulted in material misstatements in our financial statements” is amended and restated as follows:

We have previously reported material weaknesses in our internal control over financial reporting, which have been remediated; however, we may identify additional or new material weaknesses in the future that may cause us to fail to meet our reporting obligations, result in material misstatements in our financial statements or fail to prevent fraud.

Our management is responsible for establishing and maintaining internal control over financial reporting, disclosure controls, and compliance with the other requirements of the Sarbanes-Oxley Act and the rules promulgated by the SEC thereunder. A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected on a timely basis.

In prior years, we identified a material weakness in our internal control over financial reporting. While the material weaknesses related to internal controls over financial reporting previously disclosed by Sonim have since been remediated, the process of designing and implementing an effective financial reporting system is a continuous effort that requires our team to anticipate and react to changes in Sonim’s business, including its geographic expansion, to economic and regulatory environments and to expend significant resources to maintain a financial reporting system that satisfies its reporting obligations.

We cannot be certain that the measures we have taken, and expect to take, to improve our internal controls will be sufficient to ensure that our internal controls will remain effective and eliminate the possibility that other material weaknesses or deficiencies may develop or be identified in the future. If we identify future material weaknesses in our internal controls, even if quickly remediated once disclosed, investors may lose confidence in our financial statements and our stock price may decline. Implementing changes to our internal controls in connection with the remediation of any material weakness may distract our management and could require us to incur significant expenses. If we fail to remediate any material weakness, our financial statements may be inaccurate, we may be required to restate our financial statements, our ability to report our financial results in a timely and accurate basis may be adversely affected, our access to the capital markets may be restricted, our stock price may decline, and we may be subject to sanctions or investigation by regulatory authorities, which could materially and adversely affect our business and results of operations. In addition, even if we are successful in strengthening Sonim’s internal controls and procedures, in the future those internal controls and procedures may not be adequate to prevent or sufficiently identify irregularities or errors or to facilitate the fair presentation of our financial statements.
