10. REPORTABLE SEGMENTS

The Company determines its operating segments using the management approach, under which its Chief Executive Officer, as the Company’s chief operating decision maker, regularly reviews financial information to allocate resources and assess performance. The Company has identifiedtwo reportable segments, Production Services and Drilling and Evaluation Services, which provide a range of oilfield services to oil and natural gas customers across the well lifecycle. Segment performance is evaluated primarily based on revenue and segment operating income (loss), excluding corporate-level expenses such as overhead, share-based compensation, and transaction-related costs. The Company’s operations are primarily located in the MENA region.

The CODM uses segment revenue and segment operating income (loss) to assess segment performance and make resource allocation decisions. These decisions include the allocation of capital expenditures, equipment, personnel and other operational resources among the Company’s reportable segments. In making these decisions, the CODM considers each segment’s historical and expected financial performance, customer demand, market conditions, operational requirements and anticipated returns on investment. Resources are allocated with the objective of supporting operational requirements, pursuing growth opportunities and optimizing the Company’s overall financial performance.

As described elsewhere, corporate selling, general, and administrative expenses are primarily comprised of payroll and compensation costs for headquarters’ employees, professional and legal expenses relating to audit firms, consulting firms and legal counsel, and depreciation charges on headquarters’ offices and leasehold improvements.
