While Q4 seasonality is difficult to predict, the additional industry drilling activity we are seeing starting in Q2 suggests completion demand is likely to increase later this year and into 2027 ▪ We are continuing our strategy to decommission Tier II diesel assets through the end of 2026, with incremental investments favoring Emerald 100% natural gas equipment additions given favorable operational performance and returns profile of new technology vs extending the life of legacy diesel assets General Business Update ▪ We expect consolidated adjusted EBITDA1 for the second quarter of 2026 to be approximately $220 million ▪ 2026 Capital Expenditures, net of asset sales, now expected to be ~$600 million; our incremental capital investments should position us to capture strong demand and attractive long-term returns, including additional drilling rig structural upgrades supported by increasing term contract coverage, expansion of Emerald 100% natural gas completions equipment, and continued digital investments ▪ Incremental growth capital investments will be made with cash on hand, with the investments expected to mostly benefit financial results in 2027 and beyond

Adjusted gross profit is included as a supplemental disclosure because it is a useful indicator of our operating performance. Adjusted gross profit is a non-GAAP financial measure and should be considered in addition to, not as a substitute for or superior to, measures prepared in accordance with GAAP.

24Investor Presentation Patterson-UTI Reconciliation of Non-GAAP Financial Measures Cash Conversion, Drilling Services (1) Adjusted earnings before interest, taxes, depreciation and amortization ("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, net interest expense, depreciation, depletion, amortization and impairment expense (including impairment of goodwill), legal accruals and settlements 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 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. (2) We define Cash Conversion for our Drilling Services segment as Drilling Services Adjusted EBITDA less Drilling Services capital expenditures, expressed as a percentage of Drilling Services Adjusted EBITDA. We present Cash Conversion as a supplemental measure because we believe it is a meaningful indicator of the segment's ability to convert earnings into cash after reinvesting in the business. This measure is useful to investors and management in evaluating the efficiency of capital deployment and the segment's capacity to generate cash flow that may be available for financing activities or other corporate purposes. Our calculation of Cash Conversion may not be comparable to similarly titled measures used by other companies. Cash Conversion is a non-GAAP financial measure and should be considered in addition to, not as a substitute for or superior to, measures prepared in accordance with GAAP.

26Investor Presentation Patterson-UTI Reconciliation of Non-GAAP Financial Measures Unlevered Cash Conversion (1) We define Unlevered Free Cash Flow as Adjusted EBITDA less capital expenditures. Unlevered Cash Conversion is defined as Unlevered Free Cash Flow as a percent of Adjusted EBITDA. We present Unlevered Cash Conversion as a supplemental disclosure because we believe that it is an important liquidity measure and that it is useful to investors and management as a measure of the company's ability to generate cash flow, after reinvesting in the company, that could be available for financing cash flows, such as dividend payments, share repurchases and/or repurchases of long-term indebtedness. Our computations of Unlevered Free Cash Flow may not be the same as similarly titled measures of other companies. Unlevered Free Cash Flow is not intended to represent our residual cash flow available for discretionary expenditures. Unlevered Free Cash Flow is a non-GAAP financial measure that should be considered in addition to, not as a substitute for or superior to, cash flows from operations reported in accordance with GAAP.

27Investor Presentation Patterson-UTI Reconciliation of Non-GAAP Financial Measures (1) Adjusted earnings before interest, taxes, depreciation and amortization ("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, net interest expense, depreciation, depletion, amortization and impairment expense (including impairment of goodwill), legal accruals and settlements 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 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. (2) We define Net Debt as total debt, which excludes deferred financing costs and discounts and includes operating and finance lease liabilities, less cash and cash equivalents. This non-GAAP financial measure has inherent limitations and should not be considered in isolation or as a substitute for amounts reported in accordance with GAAP. We present both total debt and Net Debt because we believe these measures provide management and investors with additional useful information to assess our liquidity position. Our method of calculating Net Debt may differ from similarly titled measures used by other companies.
