There have been no changes to the accounting policies during the nine months ended September 30, 2025.

Core Laboratories Inc. uses the equity method of accounting for investments in which it has less than a majority interest and does not exercise control but does exert significant influence. Non-controlling interests have been recorded to reflect outside ownership attributable to consolidated subsidiaries that are less than 100% owned. All inter-company transactions and balances have been eliminated in consolidation.

Property, Plant and Equipment

We review our long-lived assets (“LLA”) for impairment when events or changes in circumstances indicate that their net book value may not be recovered over their remaining service lives. Indicators of possible impairment may include significant declines in activity levels in regions where specific assets or groups of assets are located, extended periods of idle use, declining revenue or cash flow or overall changes in general market conditions.

The geopolitical conflict between Russia and Ukraine, which began in February 2022 and has continued through September 30, 2025, has resulted in disruptions to our operations in Russia and Ukraine. As of September 30, 2025, our

laboratory facilities, offices, and locations in Russia and Ukraine continued to operate with no significant impact to local business operations. Therefore, we determined there was no triggering event for LLA impairment in Russia and Ukraine, and no impairment assessments have been performed as of September 30, 2025.
