Patterson-UTI Energy Reports Financial Results for the Quarter Ended December 31, 2023

HOUSTON, Texas – February 14, 2024 – PATTERSON-UTI ENERGY, INC. (NASDAQ: PTEN) today reported financial results for the quarter ended December 31, 2023.

Fourth Quarter 2023 Financial Results and Other Key Items

Management Commentary

“We achieved exceptionally strong results in our first full quarter following the closing of the NexTier and Ulterra transactions,” said Andy Hendricks, Chief Executive Officer. “Throughout the year, our U.S. Contract Drilling activity outpaced the overall industry rig count, and our outperformance in both activity and adjusted gross profit per operating day is evidence that there remains high demand for our top-tier drilling assets. Our Completion Services segment significantly beat our expectations in the fourth quarter and is performing at a high level through the ongoing integration. We are confident that our size and scale as well as our standing as a technology leader across both U.S. onshore drilling and completions positions us for success as the industry continues to evolve.”

Mr. Hendricks continued, “The NexTier and Ulterra transactions have exceeded our expectations through the first 5+ months, and both still offer incremental opportunities to grow profitability beyond what we are realizing today. For the NexTier merger, by the start of 2024 we achieved an annualized synergy run-rate of more than $100 million towards our $200 million synergy target, and for the Ulterra acquisition we see significant international growth potential over the next several years. NexTier and Ulterra will make us a stronger company over the long-term and create significant value for our shareholders as we realize the benefits of our combined expertise and continue to advance our technology lead over much of the industry.”

“The outlook for U.S. drilling and completion activity reflects a shift in our industry towards reduced cyclicality compared to historical trends,” said Mr. Hendricks. “For Patterson-UTI, this creates opportunities for profitability growth, and in a steady market we would expect our returns to improve as this year progresses. To meet our customer demand for further well performance improvements, we continue to invest in technology in both our drilling and completions businesses, including investments in automation, rig component upgrades, and next generation natural gas and electric assets, where we see higher returns. By mid-year, we expect to be operating approximately 140,000 horsepower of electric frac equipment, with nearly 80% of our active fleets capable of being powered by natural gas by that time. We believe we are positioned to outperform the industry over the next year, with strong market fundamentals for high-quality drilling and completion assets.”

“The reduced cyclicality in U.S. shale is allowing us to reduce the year-to-year variability of our own capital expenditures,” said Andy Smith, Chief Financial Officer. “Our $740 million capital expenditure budget for 2024 includes sufficient strategic and conversion spending to allow us to enhance our fleet to improve our competitiveness over the long-term, while still generating substantial free cash flow through the cycle. Importantly, we are focused on growing our profitability in the most capital efficient manner, and we believe the investments we are making will allow us to improve our returns through the year even without higher industry activity. Our 2024 capital expenditure budget is down substantially from the combined company capex in 2023, and we expect to generate significant free cash flow in 2024, with a goal to convert at least 40% of our adjusted EBITDA to free cash flow on an annual basis. Given where our shares are trading today, we believe the best use of our free cash flow at this time is to accelerate our shareholder returns to more than 50% of free cash flow over the near-term. For 2024, our expectation is that we will use at least $400 million to pay dividends and repurchase our shares.”

Drilling Services

During the fourth quarter, Drilling Services revenue totaled $464 million. The prior quarter included the recognition of $29 million of previously deferred revenue from a customer prepayment, without which revenue in the fourth quarter would have grown 1% sequentially. Drilling Services adjusted gross profit totaled $187 million during the quarter compared to $209 million during the prior quarter. The prior quarter included $9 million in costs associated with insurance reserve adjustments and inventory write-downs. Excluding the impact of the previously deferred revenue and referenced costs in the prior quarter, fourth quarter Drilling Services gross profit would have been relatively flat.

Within the Drilling Services segment, for the fourth quarter U.S. Contract Drilling revenue was $393 million and adjusted gross profit was $177 million. U.S. operating days totaled 10,841. Average rig revenue per day decreased $1,830 sequentially to $36,280, although the prior quarter included the previously deferred revenue that positively impacted reported revenue per day by $2,630. Average rig operating costs per day increased $70 to $19,940, although the prior quarter included $790 per day from the previously mentioned insurance reserve adjustments and inventory write-downs. The average rig adjusted gross profit per operating day in U.S. Contract Drilling was $16,330, a $1,910 decrease from the previous quarter. Excluding the impact of the previously mentioned revenue and costs in the prior quarter, fourth quarter adjusted gross profit per operating day would have been down $70 from the prior quarter.

As of December 31, 2023, the Company had term contracts for drilling rigs in the United States providing for future dayrate drilling revenue of approximately $700 million. Based on contracts currently in place, the Company expects an average of 79 rigs operating under term contracts during the first quarter of 2024 and an average of 52 rigs operating under term contracts over the four quarters ending December 31, 2024.

For the fourth quarter, other Drilling Services revenue, which primarily includes International Contract Drilling and Directional Drilling, was up 2% sequentially to $70 million, with adjusted gross profit of $10 million. The improvement was largely due to better results in our Directional Drilling business.

Completion Services

The fourth quarter was the first full quarter of reported results since we completed the merger with NexTier Oilfield Solutions.

Completion Services utilization was stronger than expected in the fourth quarter. Fourth quarter Completion Services revenue totaled $1,014 million, with adjusted gross profit of $232 million. Fourth quarter revenue in the Completion Services segment was down 2% sequentially, which outperformed the market, compared to the third quarter combined revenue of NexTier and the Company’s legacy Pressure Pumping segment. Our Completion Services segment saw improved returns in the quarter even on slightly lower revenue, a function of the benefit from the ongoing merger integration as well as from the benefit of our wellsite integration strategy that delivered strong results for both our company and our customers.

We continued to see strong demand for natural gas-powered completion equipment as well as for our wellsite integration services, including wireline, Power Solutions CNG, and last mile logistics, which helped revenue and profitability in the segment outperform our expectations for the quarter. There has been strong adoption of our wellsite integration services onto legacy Patterson-UTI fleets, which gives us confidence that the merger with NexTier is likely to unlock significant value over the long-term.

Drilling Products

The fourth quarter was the first full quarter of reported results since we completed the acquisition of Ulterra Drilling Technologies.

As a result of the Ulterra transaction, the Company was required to record certain assets and liabilities of Ulterra at fair value, resulting in a step-up in value of drill bits that Ulterra held at the time the transaction was closed. This step-up in value will continue to impact the reported results for Ulterra until the Company has fully consumed the impacted assets. During the fourth quarter, the step-up in value increased reported segment direct operating costs by $5 million and increased reported segment depreciation and amortization by $10 million, all of which was non-cash in nature.

Fourth quarter Drilling Products revenue totaled $88 million, with adjusted gross profit of $39 million. Fourth quarter revenue in the Drilling Products business was up 1% sequentially compared to the business in the third quarter. Revenue increased sequentially despite a decline in the global rig count, with Ulterra drill bits continuing strong penetration across various domestic and international markets on steady pricing.

Other

During the fourth quarter, Other revenue totaled $18 million, a 10 percent sequential increase relative to the prior period. Other adjusted gross profit totaled $8 million during the quarter.

Outlook

At current commodity prices, we expect oil basin activity to remain relatively steady throughout the year. Activity in natural gas basins could see an impact from current low natural gas prices.

In the Drilling Services segment, we expect to operate an average of 120 U.S. rigs in the first quarter, up from an average of 118 in the fourth quarter. We believe our sequential activity will outperform the industry average in the first quarter. We expect first quarter Drilling Services adjusted gross profit will be relatively flat compared to the fourth quarter, with a relatively flat adjusted gross profit in U.S. Contract Drilling.

Completion Services activity has mostly been steady through the first quarter, although we are seeing some white space as we strategically reposition our fleets in response to natural gas prices. After finishing a stronger than expected fourth quarter, for the first quarter, Completion Services revenue is expected to be $940-950 million with approximately $750 million in direct operating costs and an adjusted gross profit of $190-200 million.

Drilling Products demand is expected to remain steady through the first quarter, given the expectation for a steady market in both the U.S. and International markets relative to what we saw in the fourth quarter. For the first quarter, Drilling Products revenue is expected to be approximately $90 million, with $50 million in direct operating costs and an adjusted gross profit of $40 million. We expect $5 million in non-cash direct operating costs associated with the step-up in value at Ulterra, without which our segment adjusted gross profit expectation would be $45 million.

For the first quarter, Other revenue and adjusted gross profit is expected to be roughly flat with the fourth quarter.

For the first quarter, we expect selling, general and administrative expense of approximately $65 million, and depreciation, depletion, amortization, and impairment expense of approximately $280 million.

For 2024, we expect an effective tax rate of approximately 24%, with annual cash taxes expected to be $35-45 million after utilizing tax attributes to offset a portion of our taxable income.

For 2024, we expect capital expenditures of approximately $740 million, comprised of $285 million for Drilling Services, $360 million for Completion Services, $55 million for Drilling Products, and $40 million for Other and Corporate.

For purposes of the shareholder return target, the Company defines free cash flow as net cash provided by operating activities less capital expenditures. The shareholder return target, including the amount and timing of any dividend payments and/or share repurchases are subject to the discretion of the Company’s Board of Directors and will depend upon business conditions, results of operations, financial condition, terms of the Company’s debt agreements and other factors.
