About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F1 · shares: The Reporting Person's previously filed Form 4 inadvertently (i) understated the number of shares of common stock of Sonim Technologies, Inc. (the "Issuer") disclosed in Columns 4 and 5 by 8,109 shares due to a mathematical error in the calculation of the value of shares for the purpose of issuance and (ii) incorrectly described the vesting schedule of issued restricted stock units (the "RSUs"). The RSUs vest in three equal annual installments on the anniversary date on which the Reporting Person was appointed as a director of the Issuer's board, subject to continuous service on each vesting date. This Form 4 corrects the above-described errors by increasing the number of shares and the total amount of securities beneficially owned by the Reporting Person.
