 with respect to two or more stockholders sharing the same address by delivering a single notice or proxy statement and annual report addressed to those stockholders. This process is commonly referred to as “householding.” This process benefits both stockholders and Sonim because it can significantly reduce our printing and mailing costs and eliminates unnecessary mailings delivered to your home. It also helps the environment by conserving natural resources.

Under this procedure, we are delivering a single copy of the notice of Internet availability and, if applicable, the proxy materials to multiple stockholders who share the same address unless we received contrary instructions from the impacted stockholders prior to the mailing date. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards.

Upon written or oral request, we will deliver promptly a separate copy of a separate copy of the annual report to security holders, proxy statement, or notice of internet availability of proxy materials, as applicable, to any stockholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy of a separate copy of the annual report to security holders, proxy statement, or notice of internet availability of proxy materials, as applicable, stockholders may contact our Secretary by written request to Sonim Technologies, Inc., 4445 Eastgate Mall, Suite 200, San Diego, CA 92121, or at (650) 378-8100. The same phone number and addresses may be used to notify us that you wish to receive a separate set of proxy materials in the future, or to request delivery of a single copy of our proxy materials if you are receiving multiple copies.
