Item 1.01

Entry into a Material Definitive Agreement.

As previously disclosed on the Current Report on Form 8-K filed by Sonim Technologies, Inc. (the “Company” or “Sonim”) with the Securities and Exchange Commission (the “SEC”) on July 22, 2025, the Company entered into that certain asset purchase agreement (the “Purchase Agreement”), dated as of July 17, 2025, by and among the Company, as seller, Pace Car Acquisition LLC, as buyer, (the “Buyer”), the Seller Representative named in the Purchase Agreement, and, Social Mobile Technology Holdings LLC (the “Parent”), solely for the purpose of guaranteeing complete payment and performance obligations of the Buyer contained in the Purchase Agreement. Pursuant to the Purchase Agreement, the Buyer agreed to acquire substantially all assets of the Company and its subsidiaries related to the Company’s enterprise 5G solutions business for a purchase price of $15 million in cash, subject to a customary working capital, indebtedness, and transaction expense adjustments (referred to in the Purchase Agreement as the “Adjustment Amount”).

On November 24, 2025, the Company, the Buyer, the Parent, and the Seller Representative entered into a first amendment to the Purchase Agreement (the “APA Amendment”). The APA Amendment modifies certain provisions of the Purchase Agreement, including:

	●	removal of all references to, and sections providing for or related to, the Company’s proposed reverse merger transaction (the “RTO”) and items ancillary to the RTO (e.g., the filing by the Company of a registration statement on Form S-4), as the RTO is no longer applicable to the closing of the Purchase Agreement;

	●	the addition of a requirement that, after taking into account the Adjustment Amount, if the Closing Purchase Price (as defined in the Purchase Agreement) is less than $0, the Company must pay a sufficient portion of the Company’s accounts payable so that the Closing Purchase Price is greater than $0; and

	●	the addition of the Company’s German subsidiary, Sonim Technologies Germany GmbH, to the acquired subsidiaries annex of the Purchase Agreement.

The foregoing summary of the APA Amendment and transactions contemplated thereby does not purport to be complete and is qualified in its entirety by the full text of the APA Amendment, a copy of which is filed as Exhibit 2.1 hereto and incorporated by reference herein.
