We also certify and recertify equipment for drilling contractors, and we provide electrical controls and automation to the energy, marine and mining industries.

The information throughout this report generally applies to Patterson-UTI Energy, Inc. on a company-wide basis; however, in some instances, we share details that relate to a specific business. In particular, the practices of our contract drilling business and/or our Completion Services business, our two largest businesses, are highlighted where appropriate.

Unless otherwise noted or as the context otherwise requires, the quantitative disclosures presented in this report are for the fiscal year ended December 31, 2023, and the narrative disclosures presented in this report were current as of December 31, 2023. Additionally, given the continued integration of systems and processes across Patterson-UTI, NexTier and Ulterra, the information reported is intended to include all three entities unless specifically stated otherwise.

Our sustainability report is intended to address what we view as material environmental, social and governance sustainability-related issues. In assessing the material topics to address in our sustainability report, we considered feedback from internal and external stakeholders, including customers, investors, trade associations and industry groups, and engaged with external sustainability resources for feedback and benchmarking purposes. In particular, we considered recent feedback regarding various disclosure frameworks and elected to align our disclosures following the frameworks set forth by the Sustainability Accounting Standards Board (SASB) (Oil & Gas – Exploration and Production)and Task Force on Climate-Related Financial Disclosures (TCFD). Mapping of these disclosures can be located beginning on page 54 of this report. We have also included disclosures on additional topics not covered by SASB and TCFD in response to stakeholder feedback.
