Core Laboratories Inc. (NYSE: "CLB") ("Core," "Core Lab," or the "Company") continues to evaluate and monitor the evolving geopolitical conflict in the Middle East and its effect on the Company's first quarter 2026 financial results. Core Lab is working with clients and its local teams to manage operations and mitigate impacts on project execution through a rapidly changing operating environment. The safety and security of the Company's employees remain its highest priority.

At this time, due to regional instability, including client-driven project delays, travel constraints, and supply-chain disruptions, the Company expects first quarter 2026 revenue and earnings to be below its previously issued guidance provided on February 4, 2026.

Changes in client activity levels across the Middle East are directly impacting operations in the countries where Core Lab operates. Damage to oil refining infrastructure and storage terminals has created capacity limitations, forcing operators to shut in or limit oil production. These effects have extended to regional supply chains and the maritime transportation of crude oil and refined products—particularly through the Strait of Hormuz—resulting in logistical constraints and delays in project execution. The impact has been more pronounced in Reservoir Description due to its unique role in supporting regional client studies, crude oil assay testing, and reservoir rock and fluid characterization, all of which rely on predictable field access, sample movement, and laboratory operations. Production Enhancement has been comparatively less affected; however, shipments of energetics products into certain parts of the region have been delayed or temporarily suspended.

Core's revised guidance for first quarter 2026 revenue ranges from $119,000,000 to $123,000,000, while operating income, ex-items, is projected to range from $5,700,000 to $7,100,000. The Company is now projecting Earnings Per Share, ex-items, to be between $0.05 to $0.07 for the first quarter of 2026.

Core Lab will continue to monitor developments and will provide additional updates as appropriate.
