Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies Update	2. SIGNIFICANT ACCOUNTING POLICIES UPDATE Basis of Presentation and Principles of Consolidation On May 1, 2023, Core Laboratories N.V. completed its previously announced redomestication transaction (the “Redomestication Transaction”) which through a series of steps, resulted in the merger of Core Laboratories N.V., a holding company in the Netherlands, with and into Core Laboratories Luxembourg S.A., a public limited liability company incorporated under the laws of Luxembourg, with Core Laboratories Luxembourg S.A. surviving, and subsequently the migration of Core Laboratories Luxembourg S.A. out of Luxembourg and its domestication as Core Laboratories Inc., a Delaware corporation. The Redomestication Transaction has been accounted for as a transaction between entities under common control. There is no difference between the combined separate entities prior to the Redomestication Transaction and the combined separate entities after the Redomestication Transaction, therefore, comparative information reported in these financial statements do not differ from amounts previously reported under Core Laboratories N.V.’s consolidated financial statements. These financial statements should be read in conjunction with Core Laboratories N.V.’s Quarterly Report on Form 10-Q for the three months ended March 31, 2023 and Core Laboratories N.V.’s Annual Report on Form 10-K for the year ended December 31, 2022, including Note 2 - Summary of Significant Accounting Policies. The accompanying unaudited interim consolidated financial statements include the accounts of Core Laboratories Inc. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Core Laboratories Inc.’s balance sheet information for the year ended December 31, 2023, was derived from the 2023 audited consolidated financial statements. Accordingly, these financial statements do not include all of the information and footnote disclosures required by U.S. GAAP for the annual financial statements and should be read in conjunction with the audited financial statements and the summary of significant accounting policies and notes thereto included in Core Laboratories Inc.’s Annual Report on Form 10-K for the year ended December 31, 2023, including Note 2 - Summary of Significant Accounting Policies. There have been no changes to the accounting policies of the combined entities during the nine months ended September 30, 2024. 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. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods presented have been included in these financial statements. Furthermore, the operating results presented for the three and nine months ended September 30, 2024, may not necessarily be indicative of the results that may be expected for the year ending December 31, 2024. Certain reclassifications were made to prior period amounts in order to conform to the current period presentations. These reclassifications had no impact on the reported net income or cash flows for the three and nine months ended September 30, 2023 . 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, 2024, has resulted in disruptions to our operations in Russia and Ukraine. As of September 30, 2024, all 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 in Russia and Ukraine, and no impairment assessments have been performed as of September 30, 2024 . Recent Accounting Pronouncements Issued But Not Yet Effective In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023- 07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an annual and interim basis. The amendment is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendment should be applied retrospectively to all prior periods presented in the financial statements. Upon adoption, our disclosures regarding segment reporting will be expanded accordingly. In December 2023, FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures to improve transparency of income tax disclosures, primarily by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendment is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendment should be applied prospectively; however, retrospective application is permitted. Upon adoption, our disclosures regarding income taxes will be expanded accordingly.

(2) Interest is payable semi-annually on March 28 and September 28. We, along with our wholly owned subsidiary Core Laboratories (U.S.) Interests Holdings, Inc. (“CLIH”) as issuer, have senior notes outstanding that were issued through private placement transactions. Series A and Series B of the 2021 Senior Notes were issued in 2021 (the “2021 Senior Notes”). Series A and Series B of the 2023 Senior Notes were issued in 2023 (the “2023 Senior Notes”). The 2021 Senior Notes and the 2023 Senior Notes are collectively the “Senior Notes”. We, along with CLIH, have a credit facility, the Eighth Amended and Restated Credit Agreement (as amended, the “Credit Facility”) for an aggregate borrowing commitment of $ 135.0 million with a $ 50.0 million “accordion” feature. The Credit Facility is secured by first priority interests in (1) substantially all of the tangible and intangible personal property, and equity interest of CLIH and certain of the Company’s U.S. and foreign subsidiary companies; and (2) instruments evidencing intercompany indebtedness owing to the Company, CLIH and certain of the Company’s U.S. and foreign subsidiary companies. Under the Credit Facility, the Secured Overnight Financing Rate (“SOFR”) plus 2.00 % to SOFR plus 3.00 % will be applied to outstanding borrowings. Any outstanding balance under the Credit Facility is due at maturity on July 25, 2026 , subject to springing maturity on July 12, 2025, if any portion of the Company’s 2021 Senior Notes Series A due January 12, 2026, in the aggregate principal amount of $ 45.0 million, remain outstanding on July 12, 2025, unless the Company’s liquidity equals or exceeds the principal amount of the 2021 Senior Notes Series A outstanding on such date. The available capacity at any point in time is reduced by outstanding borrowings and outstanding letters of credit which totaled approximately $ 10.9 million at September 30, 2024 , resulting in an available borrowing capacity under the Credit Facility of approximately $ 92.1 million. In addition to indebtedness under the Credit Facility, we had approximately $ 7.6 million of outstanding letters of credit and performance guarantees and bonds from other sources as of September 30, 2024. The Credit Facility and Senior Notes include a cross-default provision, whereby a default under one agreement may trigger a default in the other agreements. The terms of the Credit Facility and Senior Notes require us to meet certain covenants, including, but not limited to, an interest coverage ratio (calculated as consolidated EBITDA divided by interest expense) and a leverage ratio (calculated as consolidated net indebtedness divided by consolidated EBITDA), where consolidated EBITDA (as defined in each agreement) and interest expense are calculated using the most recent four fiscal quarters. The Credit Facility has more restrictive covenants with a minimum interest coverage ratio of 3.00 to 1.00 and permits a maximum leverage ratio of 2.50 to 1.00 . The Credit Facility allows non-cash charges such as impairment of assets, stock compensation and other non-cash charges to be added back in the calculation of consolidated EBITDA. The terms of our Credit Facility also allow us to negotiate in good faith to amend any ratio or requirement to preserve the original intent of the agreement if any change in accounting principles would affect the computation of any financial ratio or covenant of the Credit Facility. In accordance with the terms of the Credit Facility, our leverage ratio is 1.47 , and our interest coverage ratio is 6.13 , each for the period ended September 30, 2024. We are in compliance with all covenants contained in our Credit Facility and Senior Notes as of September 30, 2024. Certain of our material, wholly owned subsidiaries are guarantors or co-borrowers under the Credit Facility and Senior Notes. See Note 11 - Derivative Instruments and Hedging Activities for additional information regarding interest rate swap agreements we have entered to fix the underlying risk-free rate on our Credit Facility and Senior Notes. The estimated fair value of total debt at September 30, 2024, and December 31, 2023 , approximated the book value of total debt. The fair value was estimated using Level 2 inputs by calculating the sum of the discounted future interest and principal payments through the maturity date.

Pension and Other Postretirement Benefit Plans	8. PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS Prior to January 2020, one of our subsidiaries provided a noncontributory defined benefit pension plan covering substantially all of our Dutch employees (“Dutch Plan”) who were hired prior to 2000. This pension benefit was based on years of service and final pay or career average pay, depending on when the employee began participating. The Dutch Plan was curtailed prior to January 2020, and these employees have been moved into the Dutch defined contribution plan. However, the unconditional indexation for this group of participants continues for so long as they remain in active service with the Company.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	11. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES We are exposed to market risks related to fluctuations in interest rates. To mitigate these risks, we may utilize derivative instruments in the form of interest rate swaps. We do not enter into derivative transactions for speculative purposes. Under the Company’s Credit Facility, the SOFR plus 2.00 % to SOFR plus 3.00 % will be applied to outstanding borrowings. See Note 7 - Long-term Debt, net for additional information. The Company has elected to apply the optional expedient for hedging relationships affected by reference rate reform. Accordingly, no outstanding balance on the Credit Facility with a SOFR rate will preclude cash flow hedging with existing London Inter-Bank Offer Rate (“LIBOR”) hedging instruments. In August 2014, we entered into a swap agreement, that expired on August 29, 2024 , with a notional amount of $ 25 million (“2014 Variable-to-Fixed Swap”), and the LIBOR portion of the interest rate was fixed at 2.5 %. In February 2020, we entered into a second swap agreement with a notional amount of $ 25 million (“2020 Variable-to-Fixed Swap”), and the LIBOR portion of the interest rate was fixed at 1.3 % through February 28, 2025 . These interest rate swap agreements were terminated, dedesignated and settled in March 2021. The hedging relationship is highly effective; therefore, gains and losses on these swaps will be reclassified into interest expense in accordance with the forecasted transactions or the scheduled interest payments on the Credit Facility. At September 30, 2023 , the outstanding balance on our Credit Facility had been reduced to zero , and approximately $ 0.2 million of losses were reclassified to interest expense associated with the ineffective period of the hedging relationship, as it became probable that certain of the forecasted transactions would not occur within the originally specified time period. Remaining net losses on these swaps included in accumulated other comprehensive income (loss) as of September 30, 2024 , are $ 17 thousand all of which is expected to be reclassified into earnings within the next 12 months as interest payments are made on the Company’s Credit Facility. In March 2021, we entered into a new forward interest rate swap agreement and carried the fair value of the terminated 2014 and 2020 Variable-to-Fixed Swaps into the new agreement in a “blend and extend” structured transaction. The purpose of this forward interest rate swap agreement is to fix the underlying risk-free rate, that would be associated with the anticipated issuance of new long-term debt by the Company in future periods. The forward interest rate swap would hedge the risk-free rate on forecasted long-term debt for a maximum of 11 years through March 2033. Risk associated with future changes in the 10-year LIBOR interest rates have been fixed up to a notional amount of $ 60 million with this instrument. The interest rate swap qualifies as a cash flow hedging instrument. This forward interest rate swap agreement was terminated and settled in April 2022. The hedging relationship is highly effective, therefore, the gain on the termination of the forward interest rate swap was included in accumulated other comprehensive income (loss). On June 28, 2023, the Company issued the 2023 Senior Notes in the aggregate principal amount of $ 50 million at fixed interest rates of 7.25 % and 7.50 %. The Company has elected to apply the optional expedient for hedging relationships affected by reference rate reform. Accordingly, no outstanding balance on the 2023 Senior Notes will preclude cash flow hedging with the existing LIBOR hedging instrument. The Company recognized a gain of $ 0.4 million in earnings for the $ 10 million over hedged portion of the interest rate swap in 2023. A net gain of $ 0.3 million is included in accumulated other comprehensive income (loss) at September 30, 2024. The unamortized balance on this swap will be amortized into interest expense in accordance with the forecasted transactions or the scheduled interest payments on the 2023 Senior Notes and any future debt through March 2033. As of September 30, 2024 , the aggregated gains and losses on these interest swaps that are included in accumulated other comprehensive income (loss) are a net gain of $ 0.3 million. At September 30, 2024 , we had fixed rate long-term debt aggregating $ 110 million and variable rate long-term debt aggregating $ 32 million. The effect of the interest rate swaps on the consolidated statements of operations is as follows (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2024 2023 2024 2023 Income Statement Derivatives designated as hedges: 5 year interest rate swap $ 5 $ — $ 67 $ 211 Increase (decrease) to interest expense 10 year interest rate swap ( 240 ) ( 415 ) ( 847 ) ( 398 ) Increase (decrease) to interest expense $ ( 235 ) $ ( 415 ) $ ( 780 ) $ ( 187 )

The Redomestication Transaction has been accounted for as a transaction between entities under common control. There is no difference between the combined separate entities prior to the Redomestication Transaction and the combined separate entities after the Redomestication Transaction, therefore, comparative information reported in these financial statements do not differ from amounts previously reported under Core Laboratories N.V.’s consolidated financial statements. These financial statements should be read in conjunction with Core Laboratories N.V.’s Quarterly Report on Form 10-Q for the three months ended March 31, 2023 and Core Laboratories N.V.’s Annual Report on Form 10-K for the year ended December 31, 2022, including Note 2 - Summary of Significant Accounting Policies. The accompanying unaudited interim consolidated financial statements include the accounts of Core Laboratories Inc. and its subsidiaries for which we have a controlling voting interest and/or a controlling financial interest. These financial statements have been prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”) for interim financial information using the instructions to Form 10-Q and Article 10 of Regulation S-X. Core Laboratories Inc.’s balance sheet information for the year ended December 31, 2023, was derived from the 2023 audited consolidated financial statements. Accordingly, these financial statements do not include all of the information and footnote disclosures required by U.S. GAAP for the annual financial statements and should be read in conjunction with the audited financial statements and the summary of significant accounting policies and notes thereto included in Core Laboratories Inc.’s Annual Report on Form 10-K for the year ended December 31, 2023, including Note 2 - Summary of Significant Accounting Policies. There have been no changes to the accounting policies of the combined entities during the nine months ended September 30, 2024. 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. In the opinion of management, all adjustments considered necessary for a fair statement of the results for the interim periods presented have been included in these financial statements. Furthermore, the operating results presented for the three and nine months ended September 30, 2024, may not necessarily be indicative of the results that may be expected for the year ending December 31, 2024. Certain reclassifications were made to prior period amounts in order to conform to the current period presentations. These reclassifications had no impact on the reported net income or cash flows for the three and nine months ended September 30, 2023 .
Property, Plant and Equipment	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, 2024, has resulted in disruptions to our operations in Russia and Ukraine. As of September 30, 2024, all 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 in Russia and Ukraine, and no impairment assessments have been performed as of September 30, 2024 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements Issued But Not Yet Effective In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2023- 07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses on an annual and interim basis. The amendment is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The amendment should be applied retrospectively to all prior periods presented in the financial statements. Upon adoption, our disclosures regarding segment reporting will be expanded accordingly. In December 2023, FASB issued ASU 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures to improve transparency of income tax disclosures, primarily by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendment is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendment should be applied prospectively; however, retrospective application is permitted. Upon adoption, our disclosures regarding income taxes will be expanded accordingly.
