15. Segment, Concentration and Geographical Information

Segment Information

Public companies are required to report financial and descriptive information about their reportable operating segments as required by FASB ASC Topic No. 280, Segment Reporting (“Topic 280”). The Company has one primary business unit based on how management internally evaluates separate financial information, business activities and management responsibility: Wireless. The Wireless segment includes the Family Safety (which includes SafePath), CommSuite, and ViewSpot families of products (prior to the divestiture of ViewSpot in 2025).

The Company's chief operating decision maker (“CODM”) as such term is defined in Topic 280, is its President and CEO. As infrastructure and resources are shared across the Company’s operations, the CODM manages the Company's operations based on consolidated financial information for purposes of evaluating financial performance, investment, cash flow metrics and allocating resources.

The accounting policies of the Company's single operating segment are the same as those described in the summary of significant accounting policies appearing in Note 1. Although the CODM uses other measures of operating performance, the Company concluded that consolidated net loss is the measure required to be disclosed as the segment measure of profit or loss. Adjusted operating loss and net loss are used to evaluate the effectiveness of Smith Micro's performance and to monitor budget versus actual results. The measure of segment assets is reflected as "total assets" in the accompanying consolidated balance sheet.

Revenue and expenses regularly provided to the CODM are included in the following reconciliation of the Company's net adjusted operating loss and net loss. It includes the significant expense categories computed under U.S. GAAP, reconciled to the Company's total net loss as presented in the consolidated statement of operations.
