**PART II – RULES 12b-25(b) AND (c)**

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-26(b), the following should be completed. (Check box if appropriate)

☒ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)The reason described in reasonable detail in Part III of this Form could not be eliminated without unreasonable effort or expense;

☐ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-CEN or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

**PART III – NARRATIVE**

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Core Laboratories Inc. (the "<u>Company</u>") is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "<u>Form 10-K</u>").

The Company is unable to file the Form 10-K within the prescribed period without unreasonable effort or expense. Although management has been working diligently to complete all the required information for the Form 10-K, the Company requires additional time to perform certain accounting analyses, compile supporting documentation, and complete management's evaluation of complex accounting for income tax issues associated with the Company's operations in multiple jurisdictions, including international operations. Once management's review is completed, there could be a material, non-cash impact to the Company's financial statements, which cannot be determined at this time. In addition, the Company's management may conclude that there was a significant deficiency or material weakness in the Company's internal control over financial reporting and its disclosure controls and procedures at December 31, 2025. The evaluation of the impact on the Company's internal control over financial reporting as of December 31, 2025 must be completed prior to the filing of the Form 10-K.

This delay in filing is not the result of any disagreements with the Company's independent registered public accounting firm on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.

**PART IV – OTHER INFORMATION**

(1)Name and telephone number of person to contact in regard to this notification

<u>Christopher S. Hill, Chief Financial Officer</u>   <u>(713)</u>   <u>328-2673</u> <br> (Name) (Area Code) (Telephone Number)

(2)Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s). ☒ Yes ☐ No

(3)Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof? ☐ Yes ☒ No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

Once management's review is completed, there could be a material, non-cash impact to the Company's financial statements, which may impact the following accounts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Income Tax Receivable

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred Tax Assets/Liabilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Income Tax Expense
