PATTERSON UTI ENERGY INC (PTEN) stock intrinsic value fair value estimate & owner earnings analysis

Patterson-UTI drills and completes onshore oil and gas wells, almost entirely in the United States. It has three businesses: contract drilling (152 marketed land rigs at the end of 2025, about $1.56 billion of 2025 revenue), completion services including hydraulic fracturing ($2.89 billion), and Ulterra drill bits and downhole tools ($344 million). The September 2023 NexTier merger and the Ulterra purchase roughly doubled the company and lifted the share count from about 220 million to about 380 million. This is a deeply cyclical, capital-heavy business. Its customers' spending follows oil and gas prices, and its own record shows it: cash earnings collapsed in the 2015-2016 oil price crash and again in the 2020 shutdown, then recovered strongly by 2022-2024. Activity is falling again now. Rigs working averaged 124 in 2023, 112 in 2024 and 100 in 2025, and revenue fell from $5.38 billion in 2024 to $4.83 billion in 2025. How we measure earnings. We start from operating cash flow and strip out working-capital swings, stock compensation and the capital spending needed to keep the fleet running. On that basis, owner earnings over the last ten years ran from a loss of $0.70 a share (2017) to a profit of $1.78 (2022), with a median of about $0.74. 2025 came in at $0.62 ($237 million). Because the company carries about $1.24 billion of bonds, we value the business before interest and then deduct the debt. Adding back cash interest of about $67 million a year gives cash flow to the whole business of roughly $303 million in 2025, against $483 million in 2024 and $450 million in 2023. Over the full 2016-2025 cycle, which includes two severe downturns, the median is about $1.00 a share, or roughly $380 million on today's share count. That full-cycle median is our anchor. The first half of 2026 looked weak on the surface, with operating cash flow of only $120 million. Most of that was a temporary build in receivables and lower accrued liabilities, though. Stripping those out, the business generated about $170 million before interest in the half, an annual pace of about $340 million. Our earlier review counted that working-capital build as lost earnings and read the half as a large loss, so the previous figures are not comparable with these. Accounting points. Depreciation and amortization of $940 million in 2025 runs well above capital spending of $589 million. About $126 million of it is amortization of intangible assets bought in the mergers, which is not a cash cost. The rest reflects a fleet that is being run with less reinvestment while activity falls. We use actual cash capital spending, not depreciation, and the 2025 level was below both 2023 and 2024. Management expects about $500 million in 2026 and calls most of it recurring. The 2024 net loss of $968 million came mainly from an $885 million goodwill write-off on the frac business. That charge is not cash, but it shows that the price paid for NexTier was too high, and we carry that lesson in the cases rather than the earnings level. Base case (about $7.95 a share). Business cash flow of about $340 million in 2026, in line with the first-half pace, rising to the full-cycle median of about $370 million from 2028. It holds there through 2040 and then fades to zero over the following ten years. U.S. shale drilling has needed rigs and frac fleets for decades and this fleet is among the largest, but we cannot name evidence that the industry continues at today's scale beyond about 15 years. That values the business at about $4.2 billion. Subtracting net debt of about $1.14 billion leaves roughly $3.0 billion. No growth is credited: the company's growth has come from large mergers, not from a repeatable small-step process. Bear case (about $3.30 a share). Activity keeps sliding in 2026-2027, then a downturn as deep as 2015-2017 or 2020-2021 arrives. In those episodes, cash flow before interest fell to roughly a fifth of mid-cycle for two years. We model about $70 million and $55 million in the trough years, barely covering interest of about $67 million. The 3.95% notes ($483 million) come due in 2028 and would have to be refinanced in the trough at higher rates. Recovery stops at only $300 million a year, followed by a fade starting in 2038. The business would be worth about $2.45 billion against about $1.2 billion of debt and extra refinancing cost, leaving about $1.26 billion. Bull case (about $10.92 a share). The fleet returns to the roughly $480 million of business cash flow it actually earned in 2024 with about 112 rigs working, by 2028, holds that level through 2040 and fades thereafter. That is worth about $5.3 billion, less $1.14 billion of debt, leaving about $4.2 billion. We give no credit to new technologies, such as the natural-gas-powered frac fleets, or to share gains beyond what has already been earned. Debt. The bonds are $483 million at 3.95% due 2028, $345 million at 5.15% due 2029 and $400 million at 7.15% due 2033. Cash was $201 million at June 30, 2026, and the company was in compliance with its covenants. The 2028 and 2029 notes carry interest below today's market rates, which helps for now, but both must be refinanced or repaid within three years. That is the main pressure point in a downturn. Margin of safety price: $3.75. We are only moderately sure of the earnings level. A ten-year record with two collapses gives a fair range, but this is now a different, larger company, and its first full year after the merger already ended in a goodwill write-off. The worst plausible outcome is a long trough like 2015-2017 or 2020-2021 that lands on the 2028-2029 maturities. The structure would likely survive it: total debt is about one-third of stated equity of $3.1 billion, no bonds mature before 2028, and in past troughs the company cut capital spending to under $170 million a year and stayed cash-positive before interest. Shareholders could still face cuts to dividends and buybacks and costly refinancing. The two things we are most likely to be wrong about are the mid-cycle cash flow and how long U.S. land activity lasts. If mid-cycle is $300 million rather than $370 million, the shares are worth about $5.50. If the industry fades from 2033 rather than 2040, they are worth about $6. At $3.75, the shares sit only modestly above our bear case. If the business simply returns to its full-cycle average within about four years, the value reached is roughly what a 20% annual return requires. Meanwhile the company has paid a dividend of about $0.32 a share a year, though that would likely be cut in a deep downturn. The price assumes a holding period of four to five years, about one cycle. That is why the margin of safety price is $3.75 and not higher.
