Conflict Minerals Report

For the Year Ended December 31, 2024

This Conflict Minerals Report (the “Report”) for the reporting period ended December 31, 2024 is presented by Patterson-UTI Energy, Inc. and its consolidated subsidiaries (“we”, “us” or the “Company”) to comply with Rule 13p-1 and Form SD promulgated under the Securities Exchange Act of 1934, as amended (the “Rule”).

I. Introduction

The Company’s Business

The Company is a Houston, Texas-based leading provider of drilling and completion services to oil and natural gas exploration and production companies in the United States and other select countries, including contract drilling services, integrated well completion services and directional drilling services in the United States, and specialized drill bit solutions in the United States, Middle East and many other regions around the world. Certain of the Company’s subsidiaries manufacture and sell products for which compliance with the Rule was required for the period covered by this Report, as follows:

•Current Power Solutions, Inc. (“Current Power”), manufactures and sells electronic controls to the energy, marine and mining industries in North America and other select markets.

•Warrior Rig Technologies US LLC (“Warrior”), manufactures and sells pipe handling components and related technology to drilling contractors.

•The wireline business of NexTier Completion Solutions Inc. (“NexTier”), provides wireline services, including the manufacture and sale of addressable wireline switches to third parties.

•Mobile Data Technologies Ltd. (“MDT”) manufactures and sells data control instruments used in fracturing operations to third parties.

Products Covered by This Report

This Report relates to the products that were manufactured or contracted to be manufactured for the period covered by this Report; and that contained gold, columbite-tantalite (coltan), cassiterite and wolframite, including their derivatives, which are limited to tantalum, tin and tungsten (“3TG”), that may be considered necessary to the functionality or production of such products, and that we had reason to believe may have originated in the Democratic Republic of the Congo and adjoining countries (“Covered Countries”) and may not have come from recycled or scrap sources.

For the period covered by this Report, these product(s) are:

•with respect to Current Power, electrical apparatuses, which includes panel boards, switch boards, control boxes, and other components of assembled electrical apparatuses;

•with respect to Warrior,components related to top drives, variable frequency drives and hydraulic power units;

•With respect to NexTier, addressable wireline switches; and

•with respect to MDT, data control instruments (collectively, the “Covered Products”).

As described below, although Current Power, Warrior, NexTier and MDT (the “Subsidiaries”) do not directly purchase 3TG from mines, smelters, or refiners, nor make direct purchases of any minerals in the Covered Countries, the Subsidiaries purchase certain components and products that may contain metal, some of which may contain 3TG. These components and products are incorporated into the Covered Products and, therefore, the Covered Products are subject to the reporting obligations of the Rule. This Report covers all of theCovered Products together.

II. Due Diligence Design and Process

Our conflict minerals program is designed to conform, in all material respects, to the Organisation for Economic Co-operation and Development (the “OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas and related Supplements on Tin, Tantalum, Tungsten and on Gold (the “OECD Guidance”). In accordance with the OECD Guidance, we took the following measures as part of our due diligence process.

The Company has adopted a policy relating to Conflict Minerals (the “Company Policy”), which is available at https://investor.patenergy.com/Investors/governance/Corporate-Governance/. For humanitarian reasons, the Company’s goal is to achieve responsible sourcing of materials, products, and components necessary to the functionality of the products that it manufactures or contracts to manufacture. We have also asked our suppliers to cooperate with us as we comply with the Rule, and expect them to ask their suppliers to do the same.

As downstream companies, the Subsidiaries’ supply chains with respect to the Covered Products are complex. There are many third parties in the Subsidiaries’ supply chains with respect to the Covered Products between the ultimate manufacture of the Covered Products and the original sources of 3TG. The Subsidiaries do not directly purchase 3TG from mines, smelters, or refiners nor make direct purchases of any minerals in the Covered Countries, although the Subsidiaries purchase certain components and products that contain metal, some of which may contain 3TG. The majority of the Subsidiaries’ suppliers of these components and products are several steps removed from smelters and mines, purchasing their components and products from suppliers who are also removed from direct interaction with smelters, refiners and mines. The Company must rely on the Subsidiaries’ suppliers to provide information regarding the origin of 3TG that are included in the Covered Products. Moreover, the Company believes that the smelters and refiners (“SORs”) of the 3TG are best situated to identify the sources of 3TG, and therefore, has

taken steps to identify the applicable SORs of 3TG in the Subsidiaries’ supply chains, when possible.

The Company’s established due diligence process is designed to identify the source of any 3TG contained in its products. The Company’s due diligence process is an ongoing process carried out by a team of employees from the Company’s legal department and the Subsidiaries’ supply chain management and procurement departments. The team conducted an assessment to determine (1) which products are Covered Products, and (2) what suppliers supplied components used in the Covered Products. Once the Covered Products were identified, the team generated a list of relevant suppliers of such products.

The Company engaged an independent third-party consultant to engage with the relevant suppliers. All of the relevant suppliers were contacted through written communication making the suppliers aware of the Company’s policies regarding 3TG and requesting that the suppliers complete and return the Responsible Minerals Initiative (“RMI”) Conflict Mineral Reporting Template CMRT (“CMRT”).

Our third-party consultant reviewed and evaluated the responses that we received from suppliers for completeness and accuracy and engaged in follow-up communications with suppliers when information provided by the suppliers appeared to be incomplete and when suppliers failed to respond within a reasonable period of time. Where a supplier was unable to provide a CMRT, our third-party consultant requested information on its suppliers of products or components which may require 3TG for their production or functionality (“Tier 2 suppliers”). When contact information was provided, Tier 2 and beyond suppliers were contacted via email or phone to attempt to build a chain-of-custody back to the 3TG SORs.

For those supply chains with SORs that were known or thought to be sourcing from the Covered Countries, additional investigation was needed to determine the source and chain-of-custody of the 3TG. Our third-party consultant relied on the following internationally accepted audit standards to determine which SORs are considered “DRC Conflict Free”: the Responsible Minerals Assurance Process (RMAP), the London Bullion Market Association Good Delivery Program and the Responsible Jewellery Council Chain-of-Custody Certification. Our third-party consultant is an official vendor member of the Responsible Minerals Initiative (RMI) to further facilitate the exchange of supply chain data and technical information in the quest for global ethical sourcing of materials. This membership provided our third-party consultant access to the following working groups: Engage with the CMRT Development Team, Smelter Engagement Team, Smelter Data Management Team, RMI Stakeholders Call, and RMI Plenary.

As indicated in the Form SD, this Report is publicly available on our website at

https://investor.patenergy.com/Investors/financials/sec-filings/default.aspx.

III. Due Diligence Results

Based on the information obtained pursuant to the due diligence process, the Company does not have sufficient information with respect to the Covered Products to determine whether the 3TG in the Covered Products was sourced through a supply chain that benefitted armed groups in the Covered Countries.

The due diligence process identified over 5,000 components and products requiring assessment. These components and products were supplied to the Subsidiaries by 334 suppliers. We sent the CMRT to all of these suppliers, and we received responses from 28% of these suppliers.

Of the supplier responses, we have identified 366 smelters and refineries unique to each of the 3TG as potential sources of the 3TG in our products, of which 246 have reportedly received a compliant designation from the RMI, 3 are listed as Active, and 117 are not listed or unknown. A list of the 366 smelters identified is attached to this report. Because many of the suppliers provided information with respect to their entire supply chain, rather than specifically for the components and products supplied to the Subsidiaries, we are unable to validate the accuracy of this list.

Given the nature of the Subsidiaries’ supply chains and the need to rely upon suppliers to identify sources of 3TG in Covered Products, it has not been practical for the Company to identify specific mines or locations of origin of such 3TG. Even those suppliers who can identify particular smelters associated with their products may not have information regarding the mines from which the smelters obtain the ores used to produce the minerals, or have the ability to trace specific supplies from the smelters to the Covered Products.

IV. Future Steps to Mitigate Risk

We will continue our supply chain due diligence efforts and engagement with suppliers to identify sources of conflict minerals in order to further mitigate the risk that 3TG in our products could benefit armed groups in the Covered Countries.
