Message from Our Chief Executive Officer

2023 was an exciting year for Patterson-UTI, as NexTier Completion Solutions and Ulterra Drilling Technologies became part of our Patterson-UTI portfolio of businesses. Through these transactions, we will continue to build on serving all of our stakeholders as an industry leading drilling and completion services company.

We remain focused on investing in our people and in new technologies and continuing to operate responsibly, in order to help our customers efficiently produce the oil and gas that the world needs

We will also continue to effectively manage our sustainability-related programs for the long-term benefit of our shareholders, employees, customers.

As part of this commitment to sustainability, we aim to minimize our environmental impact in the communities in which we work and live, while providing services for our customers in a safe and responsible manner. We invest extensively in the safety, health, development and wellbeing of our people, who, through the diversity of their backgrounds, experiences and talents, are our greatest strength. We promote a respectful and supportive culture in which our employees feel valued and their contributions are recognized. We maintain a rigorous focus on ethics and integrity at every level of our operations, a practice on which all of our success depends.

Our employees and our Company have taken significant steps to positively impact sustainability-related issues, while delivering value to our customers. As a company, we remain focused on our priorities of maintaining a safe and positive work environment for our employees, providing high quality services and products to our customers, being a good steward of capital for our shareholders, and respecting the environment. We welcome your feedback.

Thank you,

Andy Hendricks
