press release 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 outcome of negotiations with Orbic and the search for strategic alternatives by the
Special Committee, Sonim&rsquo;s ability to enter strategic transactions with potential counterparties, perceived benefits of the strategic
alternatives favored by Sonim&rsquo;s board of directors, and the Special Committee&rsquo;s assessments in connection with the search
for strategic alternatives. These forward-looking statements are based on Sonim&rsquo;s current expectations, estimates and projections
about its business and industry, management&rsquo;s beliefs 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;poised,&rdquo;
&ldquo;position,&rdquo; &ldquo;possible,&rdquo; &ldquo;potential,&rdquo; &ldquo;predict,&rdquo; &ldquo;progress,&rdquo; &ldquo;promises,&rdquo;
&ldquo;roadmap,&rdquo; &ldquo;seek,&rdquo; &ldquo;should,&rdquo; &ldquo;strive,&rdquo; &ldquo;targets,&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 letter
of intent (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 and that Sonim&rsquo;s stockholders do not approve
the proposed transaction; 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; the risk that the LOI may be terminated in circumstances that require Sonim to pay a termination fee; 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; risk that the current board of directors of Sonim loses proxy contest and the new directors&rsquo; slate
determines to terminate the proposed transaction (whether at the state of LOI or definitive agreement); risks related to the possible
failure of Sonim to achieve earn-out; 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>
