National Energy Services Reunited Corp. (NESR) stock intrinsic value fair value estimate & owner earnings analysis

National Energy Services Reunited (NESR) is a Houston-headquartered oilfield services company that earns about 99% of its revenue in the Middle East and North Africa, mostly from national oil companies. Production Services (hydraulic fracturing, coiled tubing, completions, specialty chemicals) was 62% of 2025 revenue of $1,324 million; Drilling and Evaluation Services (directional drilling, well testing, wireline, slickline and its newer Roya drilling tools) was 38%. Revenue has grown from $1,146 million in 2023 to $1,302 million in 2024 and $1,324 million in 2025. How we measure earnings. We take operating cash flow, remove the swing from working capital (receivables, payables and similar), subtract stock compensation, and subtract the capital spending needed just to keep the equipment base running. Per share, that gave $1.00 in 2023 (precisely $0.995), $1.47 in 2024 and $0.67 in 2025. Only three years of filing data were available, so the anchor is the median of those three, $1.00 per share. 2025 fell mainly because capital spending rose to $143 million (about equal to depreciation and amortization of $142 million) and the cost of services rose to 87.6% of revenue from 84.0%, which management attributes to a higher cost structure ahead of expected activity levels in Saudi Arabia. Production Services revenue also fell to $816 million from $878 million, which management attributes to fewer fracturing stages during a contract transition and lower coiled tubing activity in Saudi Arabia. 2025 operating cash flow of $264 million looks better than it is: it includes a net working-capital inflow of about $48 million, driven by a $116 million rise in payables, which we strip out. Owner earnings fell about 55% in 2025; our base case starts at $1.00, a return to the middle of what the business has already earned, not growth. Why that return is reasonable. Operating cash flow was $204.8 million in the first half of 2026 versus $119.0 million a year earlier, revenue was $925 million versus $630 million, and net income was $67.8 million versus $25.6 million. That corroborates a level at least as high as the anchor. We do not raise the anchor itself, because capital spending also rose to $110 million from $60 million in the same period, and we could not review the narrative of the quarterly report to see what caused the step-up. Base case ($9.40 per share): owner earnings stay at $1.00 for ten years, then fade to zero over the following ten years, because the acquired customer relationships (amortized at $18.8 million a year from the 2018 GES and NPS deals and the 2020 SAPESCO deal) and the multi-year contracts cannot be assumed to last forever. No growth is credited. The Roya drilling platform has multi-year contracts in Kuwait, Oman and Saudi Arabia, but no contracted volumes or backlog are disclosed, so no value is assigned to it beyond what already shows in results. Bear case ($2.90): one customer accounted for 49% of 2025 revenue (54% in 2024) and the filing states contracts can be terminated or renewed on worse terms. Bear assumes owner earnings of $0.40 per share, about 40% below the weakest year on record, for ten years and nothing after. Debt adds to this case: borrowings were $310.1 million at year-end 2025, including a $258.0 million term loan due November 4, 2027 at about 7.1%, and the revolving credit facility had only been extended to February 4, 2026 with lenders still in discussion at the filing date. Bull case ($15.00): owner earnings of $1.60 per share, modestly above the $1.47 already achieved in 2024 and consistent with the first-half 2026 cash flow, for ten years, then the same ten-year fade. Regional conflict escalation, market recovery or oil price moves are not credited. What we checked. Capital spending roughly equals depreciation and amortization, so treating nearly all of it as maintenance is consistent. The filing notes that a major military conflict involving the United States, Israel and Iran began on February 28, 2026, closing parts of regional airspace, and that the company was not aware of any adverse impact on its operations at the time of filing. We treat this as a risk in the bear case rather than something we can size. What would make these estimates wrong: loss or repricing of the largest customer, tighter margins persisting, difficulty refinancing the 2027 term loan, or regional conflict disrupting operations. Margin-of-safety price: $5.00 per share, a discount of roughly 47% to the base case, reflecting customer concentration, leverage and regional risk.
