Patterson-UTI Energy Reports Financial Results for the Quarter Ended September 30, 2026

HOUSTON, Texas – October 28, 2026 – PATTERSON-UTI ENERGY, INC. (NASDAQ: PTEN) today reported financial results for the quarter ended September 30, 2026.

Third Quarter 2026 Financial Results and Other Key Items

•Third Quarter 2026 Total Revenue of $1.3 billion, a 9% sequential increase

•Third Quarter 2026 Net Income Attributable to Common Stockholders of $28 million

•Third Quarter 2026 Adjusted EBITDA(1) of $264 million

•Declared a quarterly dividend of $0.10 per share, payable on December 15, 2026 to holders of record as of December 1, 2026

Management Commentary

“We are benefiting from increased U.S. onshore drilling and completion demand, which is supporting stronger pricing and returns,” said Andy Hendricks, Chief Executive Officer. “Our teams executed well during the quarter, and investments in our fleet and digital and automation capabilities are delivering differentiated operational performance for our customers. As these capabilities continue to gain momentum and industry demand strengthens, we expect further improvements in financial performance, and believe we are well positioned to improve our market position.”

“The commodity price environment continues to support higher customer budgets, and our discussions indicate the likelihood for additional rig reactivations and increased completion demand in 2027,” continued Mr. Hendricks. “In Drilling Services, customer programs are increasingly requiring upgraded rigs with advanced digital and automation capabilities and larger structures designed to drill deeper wells and longer laterals more efficiently. Demand for these capabilities is supporting strong pricing for our highest-specification rigs. In Completion Services, pricing momentum remains positive, particularly for natural gas-powered assets, which provides a substantial fuel-cost advantage over diesel equipment. Natural gas powered frac equipment remains in very short supply, and further pricing improvement will be necessary to support the investment required to meet industry demand. These market conditions should allow us to create additional value for our shareholders.”

“We generated strong free cash flow during the quarter, reinforcing our confidence in our outlook,” said Andy Smith, Chief Financial Officer. “We expect free cash flow to remain strong in the fourth quarter and increase meaningfully in 2027 compared with 2026. During the third quarter, we returned approximately $62 million to shareholders, including $24 million for share repurchases. We continue to evaluate a range of capital-allocation opportunities, including high-return strategic investments, additional cash returns to shareholders, and debt reduction. Our priority remains maximizing return on capital, while maintaining the long-term flexibility of our balance sheet.”

Drilling Services

Third quarter Drilling Services revenue was $417 million, and adjusted gross profit(2) was $149 million.

U.S. Contract Drilling operating days totaled 9,249 in the third quarter, with an average of 101 rigs operating. Activity increased throughout the quarter, and we exited the period with 104 rigs operating. Demand was particularly strong for rigs returning to service following structural upgrades, supporting premium pricing for our highest specification rigs. Growth was concentrated in oil-producing basins, particularly the Rockies and Permian, while natural gas activity remained steady compared with the beginning of the third quarter. Our Directional Drilling business also benefited from increased demand and greater well complexity, with results outpacing the overall industry drilling activity with stronger margins.

Completion Services

Third quarter Completion Services revenue totaled $808 million, with adjusted gross profit of $133 million.

Completion Services results improved sequentially, supported by a mid-single-digit pricing increase compared with the second quarter. Total completion activity declined modestly as several fleets experienced elevated non-productive time late in the quarter, primarily due to temporary sand availability constraints in South Texas and trucking delays in the Permian Basin. Excluding these short-term disruptions, fleetwide utilization remained very strong, with positive pricing momentum continuing throughout the quarter and into the fourth quarter. Demand was particularly robust for equipment capable of using natural gas as a fuel. By the end of 2026, approximately 90% of our active fleet will be natural gas capable.

Drilling Products

Third quarter Drilling Products revenue totaled $110 million, with adjusted gross profit of $51 million.

Drilling Products delivered its strongest quarterly revenue and adjusted gross profit since Patterson-UTI acquired Ulterra in 2023, with revenue increasing 21% sequentially and improved margins. Strong U.S. demand drove a company record revenue per industry rig and supported higher pricing. International revenue also increased sequentially, reaching a company record for the second consecutive quarter. This performance reflects the team's effective management of challenges related to the conflict in the Middle East, which is our largest international market.

Other

Third quarter Other revenue totaled $6 million, with adjusted gross profit of $4 million.

Outlook

In Drilling Services, we expect to operate an average of approximately 104 rigs in the United States during the fourth quarter and exit 2026 above that level, with additional rig reactivations anticipated in the first quarter of 2027. Results should benefit from continued pricing momentum, including higher dayrates across all rig classes and the deployment of upgraded rigs at dayrates above our current average. We expect to incur reactivation costs during the quarter as we prepare additional rigs for reactivation late in the fourth quarter and in early 2027, and we anticipate additional costs as we wind-down our operations in Colombia. Overall, we expect Drilling Services adjusted gross profit of $150 million in the fourth quarter.

In Completion Services, we expect fourth quarter adjusted gross profit of $140 million, supported by activity levels broadly consistent with the third quarter and additional pricing improvements. We anticipate some seasonal and holiday impact in the fourth quarter, although at this time it appears likely that it will be less pronounced than in prior fourth quarters. As we deploy new Emerald 100% natural gas powered equipment, we will continue to decommission diesel-powered assets and therefore do not expect active horsepower to increase through the first half of 2027.

In Drilling Products, we expect fourth quarter adjusted gross profit to decline 5-10%, sequentially, primarily reflecting the expectation for lower drilling activity in Saudi Arabia due to ongoing geopolitical unrest in the region.

We expect Other adjusted gross profit in the fourth quarter to be steady compared to the third quarter.

For the fourth quarter, we expect general and administrative expense to be approximately $70 million and depreciation, depletion, amortization, and impairment expense to be approximately $220 million.

Except for cash dividends per common share, all references to “per share” in this press release are diluted earnings per common share as defined within Accounting Standards Codification Topic 260.

(1)Certain Colombia contract drilling exit costs represent inventory and other asset write-downs recorded in direct operating expenses within the consolidated statements of operations. These costs were excluded from Adjusted EBITDA as they relate to our decision to exit our Colombia contract drilling operations and are not considered representative of ongoing operating performance.

(2)Noncontrolling investment write-down represents an impairment charge of certain minority equity investments. The charge was excluded from Adjusted EBITDA as it represents a non-operating item.

(3)Legal accruals and settlements represent net expenses (income) arising from certain significant legal matters, including settlement activity and reserve adjustments related to prior-year claims. Unlike routine legal costs incurred in the ordinary course of business, these infrequent items are excluded from Adjusted EBITDA because management does not consider them representative of our current period operating performance.

(4)Adjusted EBITDA is not defined by accounting principles generally accepted in the United States of America (“GAAP”). We define Adjusted EBITDA as net income (loss) plus income tax expense (benefit), net interest expense, depreciation, depletion, amortization and impairment expense, certain exit costs, noncontrolling investment write-down, certain significant legal accruals and settlements, impairment of goodwill, certain gains or losses on asset disposals and merger and integration expense. We present Adjusted EBITDA as a supplemental disclosure because we believe it provides, to both management and investors, additional information with respect to the performance of our fundamental business activities and a comparison of the results of our operations from period to period and against our peers without regard to our financing methods or capital structure. We exclude the items listed above from net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDA should not be construed as an alternative to the GAAP measure of net income (loss). Our computations of Adjusted EBITDA may not be the same as similarly titled measures of other companies.

Adjusted gross profit is included as a supplemental disclosure because it is a useful indicator of our operating performance.
