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 growth of the AI market, the anticipated terms of the proposed transaction, and potential benefits of
the proposed transaction to Sonim&#8217;s stockholders. These forward-looking statements are based on Sonim&#8217;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 &#8220;achieve,&#8221; &#8220;aim,&#8221; &#8220;ambitions,&#8221;

&#8220;will,&#8221; &#8220;would,&#8221; 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&#8217;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&#8217;s common stock; the risk that the current board of
directors of Sonim loses the proxy contest and the new directors&#8217; 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 &#8220;Risk Factors&#8221; included
in Sonim&#8217;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>

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>
