Amendment Description This Amendment No. 1 on Form 10-K/A (“Amendment No. 1”) amends our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (“Original Filing”), filed with the U.S. Securities and Exchange Commission (“SEC”) on March 21, 2022 (“Original Filing Date”). The sole purpose of this Amendment No. 1 is to include the information required by Items 10 through 14 of Part III of Form 10-K (the “Part III Information”) and to delete the disclosures regarding incorporation by reference on the front cover page of the Original Filing. The Part III Information was previously omitted from the Original Filing in reliance on General Instruction G(3) to Form 10-K, which permits the information in the above referenced items to be incorporated in the Form 10-K by reference from our definitive proxy statement if such statement is filed no later than 120 days after our fiscal year-end. We are filing this Amendment No. 1 to include Part III information in our Form 10-K because we will not file a definitive proxy statement containing such information within 120 days after the end of the fiscal year covered by the Original Filing. In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended (“Exchange Act”), the Cover Page, Part III, Items 10 through 14 and Part IV, Item 15 of the Original Filing are hereby amended and restated in their entirety. This Amendment No. 1 does not amend, modify, or otherwise update any other information in the Original Filing. Accordingly, this Amendment No. 1 should be read in conjunction with the Original Filing. In addition, this Amendment No. 1 does not reflect events that may have occurred subsequent to the Original Filing Date. Throughout this Amendment No. 1, references to the “Company,” “Sonim,” “we,” “our,” and “us” refer to Sonim Technologies, Inc. and its wholly owned and consolidated subsidiaries.
