This Conflict Minerals Report (the “Report”) for the reporting period ended December 31, 2018 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”).

The Company is a Houston, Texas-based oilfield services company that primarily owns and operates one of the largest fleets of land-based drilling rigs in the United States and a large fleet of pressure pumping equipment. One of the Company’s subsidiaries, Warrior Rig Technologies Limited (“Warrior”), manufactures and sells pipe handling components and related technology to drilling contractors. Due to the acquisition of Warrior and its manufacturing business by the Company in November 2016, the Company is subject to the Rule for reporting periods beginning with the year ended December 31, 2018.

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 top drives, make/break machines, variable frequency drives and hydraulic power units (collectively, the “Covered Products”).

As described below, although Warrior does not directly purchase 3TG from mines, smelters, or refiners nor make direct purchases of any minerals in the Covered Countries, Warrior purchases 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 the Covered Products together.

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://patenergy.com/investors/corporate-governance/default.aspx. For humanitarian reasons, the Company is committed to the 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 a downstream company, Warrior’s supply chain with respect to the Covered Products is complex. There are many third parties in Warrior’s supply chain with respect to the Covered Products between the ultimate manufacture of the Covered Products and the original sources of 3TG. Warrior does not directly purchase 3TG from mines, smelters, or refiners nor make direct purchases of any minerals in the Covered Countries, although Warrior purchases certain components and products that contain metal, some of which may contain 3TG. The majority of Warrior’s 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 Warrior’s 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 Warrior’s supply chain.

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 Warrior’s 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. The consultant conducted necessary 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”). These Tier 2 suppliers, and subsequent tiers of suppliers as needed, were then engaged. 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.

If the SOR was not certified by these internationally-recognized schemes, our third-party consultant attempted to contact the SOR to gain more information about their sourcing practices, including countries of origin and transfer, and whether there were any internal due diligence procedures in place or other processes the SORs takes to track the chain-of-custody on the source of its mineral ores. Relevant information reviewed included: whether the SOR had a documented, effective and communicated conflict-free policy, an accounting system to support a mass balance of materials processed, and traceability documentation. Internet research was also performed to determine whether there were any outside sources of information regarding the SOR’s sourcing practices.

As indicated in the Form SD, this Report is publicly available on our website at https://patenergy.com/investors/financial-information/sec-filings/default.aspx.

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 1,240 components and products requiring assessment. These components and products were supplied to Warrior by 64 suppliers. We sent the CMRT to all of these suppliers, and we received responses from 52% of these suppliers.

Of the supplier responses, we have identified 317 smelters and refineries unique to each of the 3TG as sources of the 3TG in our products, of which 255 have reportedly received a compliant

designation from the RMI, 5 are listed as Active, and 57 are not listed or unknown. A list of the 317 smelters identified is attached to this report.

Given the nature of Warrior’s supply chain 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.

We intend to 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.
