What Patterson-UTI Energy, Inc. told the SEC could break it.

As an oilfield-services provider, Patterson-UTI's activity levels are fundamentally a function of commodity prices: it explicitly tracks quarterly average oil prices against its quarterly average U.S. operating rig count as the key market-condition metric, because customer drilling and completion budgets — and therefore demand for its drilling services, completion services and drilling products — rise and fall with oil and natural gas prices. A sustained decline in crude/gas prices would reduce rig demand, pricing and utilization across its fleet. This commodity-cycle dependence is the dominant demand-shock channel for the company.

“Quarterly average oil prices and our quarterly average number of rigs operating in the United States for 2023, 2024 and 2025 are as follows:”

Patterson-UTI's oilfield-services revenue is concentrated among a relatively small set of exploration & production customers. In 2025 its ten largest customers generated approximately 57% of consolidated operating revenue and its five largest about 39%, with a single customer accounting for roughly $597 million, or ~12% — a level sustained across years (~11% in 2024, ~14% in 2023, spanning drilling, completion and drilling-products businesses). Because that demand depends on customers' drilling/completion budgets, the loss of, or a budget cut by, one or a few large E&P customers would materially reduce revenue. The customers are unnamed in the filing, so this registers as a concentration risk rather than named edges.

“With respect to our consolidated operating revenues in 2025, we received approximately 57% from our ten largest customers and approximately 39% from our five largest customers. During 2025, one customer accounted for approximately $597 million, or approximately 12%, of our consolidated operating revenues.”

Patterson-UTI depends on a limited number of suppliers for certain of the materials used across its drilling, completion and drilling-products operations, and on third-party trucking companies to deliver them. It notes it may not always be able to arrange alternatives if it cannot reach agreement with a supplier or if a supplier (including a trucking company) fails to deliver on time, and that some supply arrangements obligate it to purchase the material or pay liquidated damages. A supplier or logistics disruption could halt service delivery or trigger contractual penalties. Suppliers and the specific materials are not named, so this registers as a limited-/sole-source dependence risk.

“Given the limited number of suppliers of certain of our materials, we may not always be able to make alternative arrangements if we are unable to reach an agreement with a supplier for delivery of any particular material or should one of our suppliers, including trucking companies, fail to timely deliver our”
