CORE LAB REPORTS SECOND QUARTER 2026 RESULTS

Core Laboratories Inc. (NYSE: "CLB") ("Core," "Core Lab," or the "Company") reported second quarter 2026 revenue of $124,600,000.

Core's operating income was $9,200,000, with earnings per diluted share ("EPS") of $0.13, all in accordance with U.S. generally accepted accounting principles ("GAAP"). Operating income, ex-items, a non-GAAP financial measure, was $9,400,000, yielding operating margins of 8%, and EPS, ex-items, of $0.11. A full reconciliation of non-GAAP financial measures is included in the attached financial tables.

Core's CEO, Larry Bruno, stated, "Our second quarter results displayed sequential improvement in revenue, operating income and earnings per share despite continued geopolitical conflicts that affected portions of our business, particularly Reservoir Description. Notably, we saw improvement in activity in Africa, U.S., and Asia-Pacific regions, where operators continued to call on Core Lab's specialized technical expertise to facilitate critical reservoir characterization and production optimization projects. In addition, higher sequential product sales and completion diagnostic service activity were achieved across many regions including the U.S., while international growth of Production Enhancement's products and services reflected the expanded adoption of our innovative technologies.

These events negatively impacted demand for services in both the directly affected regions and across the Company's international crude oil assay laboratory network. Operating income on both a GAAP basis and ex-items was $3,700,000, yielding operating margins of 5%. Margins were impacted by: 1) reduced client activity in the Middle East, 2) lower global crude assay activity resulting from disruptions to hydrocarbon cargo shipments through the Strait of Hormuz, and 3) increased military action and expanded European sanctions associated with the Russia-Ukraine conflict. Core Lab has maintained its operational capabilities and cost structure in the Middle East, reflecting its expectation that hydrocarbon trading routes and client activity will normalize over time. The Company has taken steps to improve profitability in Russia-Ukraine operations. During the second quarter of 2026, Core Lab was engaged to support multiple exploration, appraisal, and carbon storage projects across...
