On July 1, 2025, Sonim Technologies, Inc. (the “Company”) priced a best-efforts public offering (the “Offering”) of 7,400,000 shares of its common stock at a public offering price of $0.75 per share. In connection with the Offering, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with certain investor signatories thereto for the purchase of shares of common stock described above.

Roth Capital Partners (the “Placement Agent”) served as the exclusive placement agent in connection with the Offering. The Company paid the Placement Agent a cash fee of 7.0% of the aggregate gross proceeds raised at the closing of the Offering, and reimbursement of certain expenses and legal fees in the amount of $100,000. The Company also issued to designees of the Placement Agent warrants to purchase up to an aggregate of 208,875 shares of Common Stock (the “Placement Agent Warrants”). The Placement Agent Warrants have an exercise price of $0.75 per share, are not exercisable until the 181^st day following the closing (or January 2, 2026), and expire on July 2, 2030. The exercise prices of the Placement Agent Warrants are subject to appropriate adjustment in the event of stock dividends, stock splits, stock combinations, reorganizations or similar events affecting the Common Stock. Subject to limited exceptions, a holder of Placement Agent Warrants will not have the right to exercise any portion of its Warrants if the holder (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of common stock in excess of 4.99% (or, upon election by a holder prior to the issuance of any Warrants, 9.99%) of the shares of common stock then outstanding. At the holder’s option, upon notice to the Company, the holder may increase or decrease this beneficial ownership limitation not to exceed 9.99% of the shares of Common Stock then outstanding. The Purchase Agreement contains customary representations, warranties, and covenants by the Company. It also provides for customary indemnification for losses or damages arising out of or in connection with the Offering, including for liabilities under the Securities Act, other obligations of the parties and termination provisions.

The shares of common stock and the Placement Agent Warrants described above and the underlying shares of common stock were offered pursuant to a Registration Statement on Form S-1, as amended (File No. 333-288221) (the “Registration Statement”), which was declared effective by the Securities and Exchange Commission (the “SEC”) on June 30, 2025.

The closing of the Offering occurred on July 2, 2024. The estimated net proceeds of the Offering are estimated to be approximately $4.9 million, after deducting the Placement Agent fees and expenses and other estimated offering expenses payable by the Company. The Company intends to use the net proceeds of the Offering for overall business strategy, for working capital purposes and for general corporate purposes, which may include repayment and refinancing of our indebtedness.

The foregoing summaries of the Purchase Agreement and Placement Agent Warrants do not purport to be complete and are qualified in their entirety by the forms of such documents, which are filed as Exhibits 4.1 and 10.1 to this report.
