**Section 1 – Conflict Minerals Disclosure**

**Item 1.01 Conflict Minerals Disclosure and Report**

References to "Core Lab", the "Company", "we", "our", and similar phrases relate collectively to Core Laboratories Inc. and its consolidated affiliates.

**Background - The Dodd Frank Act**

In August 2012, the United States Securities and Exchange Commission ("SEC") issued Release No 34-67716 regarding Rule 13p-1 (the "Rule"), the SEC's final rule implementing Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the "Act"). Under the Rule, SEC registrants are required to disclose their use of "conflict minerals", on an annual basis, if those minerals are necessary to the functionality or production of a product manufactured by the registrant.

Section 1502(e)(4) of the Act defines "conflict minerals" to consist of (A) columbite-tantalite, also known as coltan (the metal ore from which tantalum is extracted), cassiterite (the metal ore from which tin is extracted), gold, and wolframite (the metal ore from which tungsten is extracted), or their derivatives, which are commonly referred to as tin, tantalum, tungsten and gold ("3TG") or (B) any other mineral or its derivatives determined by the United States Secretary of State to be financing conflict in the Democratic Republic of the Congo ("DRC") or an adjoining country (collectively, the "Cover Countries").

**Outcome of the Company's 2025 Review**

During 2025, we evaluated 100% of the parts and materials necessary to the functionality or production of products manufactured by us or contracted to be manufactured for us and determined that the Company manufactures or contracts to manufacture some products that contain 3TG. We conducted a reasonable country of origin inquiry ("RCOI") to determine if the 3TG in any of our products originated in the Covered Countries by requesting a conflict minerals compliance certification from each of our suppliers providing these raw materials or products that contain 3TG.

In response to our request, each of our suppliers certified that no 3TG originating from the Covered Countries are included in any of the raw materials or products they provide us and further, that each of them has adopted a supply chain policy consistent with the policies of the Organization for Economic Cooperation and Development set forth in its guidance document entitled "OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas" dated April, 2016. All potential new suppliers are required to provide this certification to us before we will enter into a contract with them.

Based upon the results of our RCOI, we have no reason to believe that any 3TG necessary to the functionality or production of products we manufactured or contracted to manufacture during 2025 may have originated in the Covered Countries. The ethical sourcing of minerals is an important part of our mission to ensure safe and fair working conditions in our supply chain. We strive to use only conflict-free minerals in our products.
