Sonim Technologies Files Preliminary Proxy Statement, Advancing Asset Purchase by NEXA Mobility

Company announces Special Meeting of Stockholders to vote on proposed Asset Purchase Agreement

San Diego, CA – (NEWSFILE) – November 25, 2025 – Sonim Technologies, Inc. (NASDAQ: SONM) today announced the filing of a preliminary proxy statement with the U.S. Securities and Exchange Commission (the “SEC”) in connection with a special meeting of stockholders (“Special Meeting”) to consider and vote on the proposed sale of substantially all of Sonim’s assets to NEXA Mobility NEXA (formerly Social Mobile).

Asset Purchase Agreement

On July 17, 2025, Sonim entered into an asset purchase agreement under which NEXA will acquire Sonim’s assets and assume its current liabilities for a total consideration of $15 million, plus a potential $5 million earn-out, in an all-cash transaction.

Special Stockholders’ Meeting

Sonim filed its preliminary proxy statement on November 25, 2025. At the Special Meeting, stockholders will vote on the proposed asset sale. If approved, the transaction is expected to close as soon as practicable after the special meeting, subject to the satisfaction of customary closing conditions. The date, time, record date, and other details for the special meeting will be provided in definitive proxy materials to be filed with the SEC and mailed to stockholders of record.

In addition to the proposed asset sale to NEXA, Sonim is pursuing a separate transaction involving Sonim’s public company vehicle. This contemplated transaction would be independent of, and in addition to, the asset sale, and is intended to increase value for Sonim’s stockholders. No assurance can be given that such separate transaction will be consummated.
