Patterson-UTI Energy (NASDAQ: PTEN) generated $4.83 billion in revenue for full year 2025, operating as one of the largest integrated drilling and completions providers in the United States. The company’s current scale is the direct product of its September 2023 merger with NexTier Oilfield Solutions — a $5.4 billion all-stock combination that created a single platform covering contract drilling, hydraulic fracturing, directional drilling, and drilling products under one corporate structure. Q1 2026 earnings, reported April 23, 2026, showed the combined business delivering strong field execution as rig count begins its expected second-half recovery.
The NexTier Merger: What Changed and Why It Mattered
Before September 2023, Patterson-UTI was a contract drilling company and NexTier was a well completions specialist — two separate businesses serving the same E&P customers at different stages of the well lifecycle. The merger eliminated that separation. The combined Patterson-UTI Energy brought 172 super-spec drilling rigs together with NexTier’s 45 active frac spreads and 3.3 million hydraulic fracturing horsepower at close, creating a single vendor capable of managing a well from spud to flowback.
The strategic logic was the drill-to-completion offering: an integrated package allowing E&P operators to contract drilling, directional drilling, and hydraulic fracturing from a single provider with shared operational data across the full well programme. Patterson-UTI has consistently positioned its PTEN Digital Performance Center — opened in 2025 — as the infrastructure that makes this integration commercially meaningful, giving customers a single analytics environment for both drilling and completions performance.
The merger ran alongside a simultaneous acquisition of Ulterra, a drilling bit specialist that added proprietary bit technology to the services portfolio. Since close, Patterson-UTI Energy has repurchased 44 million shares — a 9% reduction in share count — while also reducing net debt by nearly $200 million, demonstrating the free cash flow capacity the merged entity generates even through a softer 2025 market cycle. The full context of that market backdrop is covered in our analysis of the top fracking companies shaping the 2026 shale industry.
Drilling Services: APEX Rigs and Cortex Automation
Patterson-UTI Energy’s drilling fleet centres on its APEX series of super-spec land rigs — high-specification walking rigs designed for long lateral horizontal drilling, equipped with the company’s proprietary Cortex Automation software. Cortex applies automated drilling process control to reduce non-productive time and drilling variability across multi-well pad programmes. Customer demand for additional Cortex automation applications and APEX rig structural upgrades for deeper geological horizons has been a consistent theme in management commentary through 2025 and into 2026.
The active US rig count averaged 95 during Q3 2025 and approximately 93 in Q4 2025, with guidance for the low-to-mid-90s range in Q1 2026 before an expected second-half recovery. The company has also pursued international deployment of idle US rigs: a multi-year lease agreement covering Argentine operations was disclosed in late 2025, monetising assets that would otherwise sit undeployed while the domestic market absorbs capacity. In the most active US shale basins — Permian, Eagle Ford, Haynesville, Bakken, and Appalachia — Patterson-UTI Energy holds a leading presence.
Completion Services: NexTier Brand, Emerald Fleet, and the EOS Platform
The well completions business continues to operate under the NexTier Completions brand following the merger. The fleet strategy has shifted materially since close: total nameplate horsepower stood at 2.7 million at the end of 2025, down more than 600,000 horsepower from the 3.3 million brought into the merger two years prior. Management has deliberately idled older diesel-powered equipment to concentrate capital and operational focus on the premium end of the market — specifically the Emerald fleet of 100% natural gas-powered hydraulic fracturing pumps.
Emerald capacity exceeded 250,000 horsepower by Q3 2025 and is set to grow again through 2026, with Patterson-UTI Energy targeting more than 15% of active horsepower running entirely on natural gas by year-end 2026, and approximately 90% capable of operating at least partially on natural gas. The fully-utilised status of the natural gas-capable fleet — confirmed in management commentary at the Q4 2025 earnings call — has insulated that portion of the business from the pricing pressure affecting lower-tier diesel equipment.
The digital layer of the completions business is EOS, Patterson-UTI Energy’s integrated completions platform launched commercially in Q3 2025. EOS incorporates the Vertex automated frac system, which delivers closed-loop automation of fracturing operations — effectively the completions equivalent of what Cortex does on the drilling side. Two multi-year commercial EOS adoption agreements were signed for 2026, and the platform achieved a record milestone of 348 continuous pumping hours on a single fleet for a Northeast customer. The growth of natural gas-powered, digitally-automated completions is part of a broader US shale evolution tracked in our report on US shale’s global expansion in 2026.
Patterson-UTI Energy in 2026: Pricing Recovery and LNG Tailwind
Full year 2025 revenue of $4.83 billion reflected a broadly softer US onshore market, with Adjusted EBITDA of $1.08 billion and capital expenditures below $600 million including the benefit of $33 million in asset sales. Free cash flow generation was sufficient to fund $119 million in shareholder returns through dividends and buybacks across the year, and the Board approved a 25% quarterly dividend increase to $0.10 per share — effective March 2026 — signalling confidence in the forward cash flow profile.
The 2026 capital expenditure budget is set at approximately $500 million gross, below $500 million net of asset sales, weighted towards the first half as new drilling and completions technologies are deployed. Management has been explicit that completions pricing needs to recover — acknowledging that pricing has been pushed down for two years and that returns need to improve before additional capacity is justified. The natural gas side of the business is already showing that pricing recovery: natural gas-capable assets are sold out, insulating Emerald fleet margins from the broader market pressure on diesel equipment.
The longer-term demand signal cited by management is LNG. Physical demand growth from US LNG export terminals is beginning to require higher gas-directed drilling and completion activity, and Patterson-UTI Energy’s gas basin exposure — particularly in Haynesville and Appalachia — positions the company to benefit as that demand begins pulling rig counts higher in the second half of 2026. The company stated in Q1 2026 earnings it is actively hiring, a direct indication that operational expansion is already underway.

What did the Patterson-UTI and NexTier merger create?
The September 2023 all-stock merger combined Patterson-UTI’s contract drilling business — 172 super-spec rigs at close — with NexTier’s well completions platform of 45 active frac spreads and 3.3 million hydraulic fracturing horsepower. The combined company, which retained the Patterson-UTI Energy name and PTEN ticker, became one of the largest integrated drilling and completions providers in the United States, with a single platform covering the full well lifecycle from spud to flowback. The completions business continues to operate under the NexTier Completions brand.
How many drilling rigs does Patterson-UTI operate in 2026?
Patterson-UTI Energy averaged approximately 93 active US drilling rigs in Q4 2025, operating in the low-to-mid-90s range entering Q1 2026. Management indicated an expected recovery in rig count in the second half of 2026, citing improving natural gas market dynamics linked to LNG export demand growth. The company also operates international rigs, including a multi-year rig lease agreement in Argentina covering assets that would otherwise be idle in the US market.
What is the Emerald fleet and why does it matter?
The Emerald fleet is Patterson-UTI Energy’s proprietary range of 100% natural gas-powered hydraulic fracturing equipment, operating under the NexTier Completions brand. Emerald capacity exceeded 250,000 horsepower by Q3 2025 and is expanding through 2026. The fleet operates at full utilisation — natural gas-capable assets are sold out — insulating Emerald margins from the pricing pressure affecting lower-tier diesel equipment. By year-end 2026, the company targets more than 15% of active horsepower running entirely on natural gas, with approximately 90% capable of at least partial natural gas operation.
What is the EOS completions platform?
EOS is Patterson-UTI Energy’s integrated digital completions platform, commercially launched in Q3 2025. It incorporates the Vertex automated frac system, which applies closed-loop automation to fracturing operations to reduce non-productive time and improve job consistency. EOS achieved a record 348 hours of continuous pumping on a single fleet for a Northeast US customer, and two multi-year commercial EOS adoption agreements were signed for 2026. The platform is the completions-side equivalent of the Cortex automation system used across Patterson-UTI’s APEX drilling rigs.
How has Patterson-UTI Energy performed financially since the NexTier merger?
Full year 2025 revenue was $4.83 billion, reflecting a broadly softer US onshore market. Adjusted EBITDA was approximately $1.08 billion. Despite the market headwinds, the company generated sufficient free cash flow to repurchase 44 million shares — reducing its share count by 9% — and reduce net debt by nearly $200 million since the merger and Ulterra acquisition closed in September 2023. The Board approved a 25% quarterly dividend increase to $0.10 per share in early 2026, and the company confirmed it is actively hiring ahead of an anticipated second-half 2026 activity recovery.
