TELOS CORP

15. SEGMENT INFORMATION

We operate our business intwo reportable and operating segments: Security Solutions and Secure Networks.

•Our Security Solutions segment is primarily focused on cybersecurity, cloud and identity solutions, and secure messaging through Xacta®, Telos Automated Message Handling System ("AMHS") and Telos ID offerings.

•Our Secure Networks segment provides secure networking architectures and solutions to our customers through secure mobility solutions, and network management and defense services.

We measure each segment's profitability based on gross profit. Our Chief Executive Officer, as the chief operating decision maker ("CODM"), evaluates the segment's performance based on metrics, such as segment revenue and gross profit, that align with our strategies and objectives, and provide a framework for the timely and rational allocation of resources between the segments.

(1) The significant segment expense categories and amounts align with the segment-level information regularly provided to the CODM.

(2) Other segment items for each reportable segment include direct labor, direct subcontractor costs, direct materials and inventory, other direct non-labor costs, fringes, overhead, and facility costs.

We account for inter-segment sales and transfers as if the sales or transfers were to third parties, that is, at current market prices, if any. There were no inter-segment sales and transfers during the three and nine months ended September 30, 2025, and 2024. Interest income, interest expense, other income and expense items, and income taxes, as reported in the consolidated financial statements, are not part of the segment profitability measure and are primarily recorded at the corporate level.

Management does not utilize total assets by segment to evaluate segment performance or allocate resources. As a result, assets are not tracked by segment, and therefore, total assets by segment are not disclosed.
