communication contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, as amended.
These statements relate to, among other things, the anticipated effects of the proposed transaction and the strategy of Sonim in connection
with strategic alternatives, the anticipated terms of the proposed transaction, potential benefits of the proposed transaction to Sonim&rsquo;s
stockholders, and anticipated difficulties in connection with certain aspects of Orbic&rsquo;s offer. These forward-looking statements
are based on Sonim&rsquo;s current expectations, estimates and projections, and certain assumptions made by Sonim, all of which are subject
to change. Forward-looking statements generally can be identified by the use of forward-looking terminology such as &ldquo;achieve,&rdquo;
&ldquo;aim,&rdquo; &ldquo;ambitions,&rdquo; &ldquo;anticipate,&rdquo; &ldquo;believe,&rdquo; &ldquo;committed,&rdquo; &ldquo;continue,&rdquo;
&ldquo;could,&rdquo; &ldquo;designed,&rdquo; &ldquo;estimate,&rdquo; &ldquo;expect,&rdquo; &ldquo;forecast,&rdquo; &ldquo;future,&rdquo;
&ldquo;goals,&rdquo; &ldquo;grow,&rdquo; &ldquo;guidance,&rdquo; &ldquo;intend,&rdquo; &ldquo;likely,&rdquo; &ldquo;may,&rdquo; &ldquo;milestone,&rdquo;
&ldquo;objective,&rdquo; &ldquo;on track,&rdquo; &ldquo;opportunity,&rdquo; &ldquo;outlook,&rdquo; &ldquo;pending,&rdquo; &ldquo;plan,&rdquo;

&ldquo;to be,&rdquo; &ldquo;upcoming,&rdquo; &ldquo;will,&rdquo; &ldquo;would,&rdquo; and variations of such words and similar expressions
or the negative of those terms or expressions. Such statements involve risks and uncertainties, which could cause actual results to vary
materially from those expressed in or indicated by the forward-looking statements. Factors that may cause actual results to differ materially
include, but are not limited to, the following: the ability of Sonim to meet expectations regarding the timing and completion of the
proposed transaction; the possibility that the LOI will not result in the definitive agreement; the possibility that the conditions to
the closing of the proposed transaction are not satisfied, including the risk that the required approvals are not obtained, the Sonim
Legacy Business Sale does not close, and that Sonim&rsquo;s stockholders do not approve the proposed transaction; the challenges of maintaining
Nasdaq listing and the potential necessity to implement a reverse stock-split in order to remain listed on Nasdaq; the occurrence of
any event, change or other circumstances that could result in the definitive agreement (if ever executed) being terminated or the proposed
transaction not being completed on the terms reflected in the definitive agreement, or at all; potential litigation relating to the proposed
transaction; the risk that the proposed transaction and its announcement could have adverse effects on the market price of Sonim&rsquo;s
common stock; the risk that the current board of directors of Sonim loses the proxy contest and the new directors&rsquo; slate determines
to terminate the proposed transaction (whether at the state of LOI or definitive agreement); the effect of the announcement of the proposed
transaction on the ability of Sonim to retain key personnel and maintain relationships with customers and business partners; the risk
of unexpected costs or expenses resulting from the proposed transaction and the LOI; and other risks and uncertainties, including those
described under &ldquo;Risk Factors&rdquo; included in Sonim&rsquo;s most recent Annual Report on Form 10-K and any subsequent quarterly
filings on Form 10-Q filed with the Securities and Exchange Commission (available at www.sec.gov). Sonim cautions you not to place undue
reliance on forward-looking statements, which speak only as of the date hereof. Sonim assumes no obligation to update any forward-looking
statements in order to reflect events or circumstances that may arise after the date of this release, except as required by law.</FONT></P>
