PATTERSON UTI ENERGY Business Summary

Patterson-UTI Energy Inc. (PTEN) operates as a leading provider of oilfield services, primarily generating revenue through high-specification contract drilling, integrated well completion services, and the manufacturing of advanced drilling products. Following its 2023 merger with NexTier Oilfield Solutions, the company has solidified its business into three core segments: Completion Services, which accounts for approximately 64% of total revenue through hydraulic fracturing and wireline operations; Drilling Services, contributing roughly 34% via a fleet of tier-one "super-spec" rigs; and Drilling Products, which focuses on the design and distribution of drill bits under the Ulterra brand. PTEN competes directly with industry giants such as Halliburton, Helmerich & Payne, Liberty Energy, and Nabors Industries. Within this landscape, Patterson-UTI distinguishes itself as the second-largest oilfield services provider in North America and the second-largest pressure pumper in the United States, leveraging its massive operational scale and data-driven digital platforms to optimize wellbore placement and completion efficiency. Patterson-UTI was established in its current form through the 2001 merger of Patterson Drilling Company (founded in 1978 by Glenn Patterson and Cloyce Talbott) and UTI Energy Corp. The leadership team is currently led by President and CEO William Andrew "Andy" Hendricks, Jr., a 24-year veteran of Schlumberger who has overseen the company’s technological pivot since 2012. He is supported by Executive Vice President and CFO C. Andrew Smith and Chief Operating Officer James Michael Holcomb, who has held various management roles within the organization since 1988. Following the NexTier integration, Robert W. Drummond, the former CEO of NexTier and a long-time Schlumberger executive, serves as Vice Chairman of the Board, while Curtis W. Huff, owner of Freebird Partners, serves as the Non-Executive Chairman. The company maintains a robust institutional investor base, with major holdings from BlackRock, The Vanguard Group, and Blackstone Inc., reflecting its status as a critical infrastructure player in the North American energy transition.
