TIDEWATER INC (TDW) stock intrinsic value fair value estimate & owner earnings analysis

What the business is. Tidewater owns and operates one of the largest fleets of offshore support vessels: 208 ships at the end of 2025, averaging 13.1 years old, that carry supplies, crews and equipment to offshore oil and gas rigs and platforms. It charters them by the day to energy producers. In 2025 vessel revenue was $1.34 billion, earned in West Africa ($363 million, mainly Angola), Europe and the Mediterranean ($344 million, including Norway, the United Kingdom and Egypt), the Americas ($270 million), Asia Pacific ($190 million, including Australia) and the Middle East ($173 million). Its five largest customers supplied about 30% of revenue and its ten largest about 48%. The fleet was assembled largely by acquisition: the GulfMark merger in 2018, Swire Pacific Offshore in 2022 and 37 vessels bought from Solstad in July 2023. The company went through a Chapter 11 reorganization in 2017, and its current shares date from that restructuring; there is no going-concern warning in its latest annual report. What it earns. We measure the cash an owner could take out each year: operating cash flow, with swings in receivables and payables removed, less stock compensation and the spending needed to keep the fleet working. Two judgements matter here. First, the cost of periodic drydockings ($99 million in 2025, $133 million in 2024) is treated as a real, recurring cost of staying in business, not as a timing item. Second, the large depreciation charge (about $151 million a year) is added back, as it is not a cash cost today, but the ships it represents are wearing out and very little is being spent to replace them (capital spending was only $26 million in 2025). We charge for that wear by letting each case's earnings shrink as the fleet ages out, rather than by cutting today's figure. On this basis the business lost money for owners in every year from 2018 through 2021 (from minus $2.43 to minus $0.04 a share) and then earned $1.09 a share in 2022, $2.82 in 2023, $5.07 in 2024 and $5.36 in 2025. Before interest, the cash the business produced was roughly $318 million in 2025, little changed from $336 million in 2024. A 2025 non-cash tax benefit of $196 million from recognizing past tax losses boosted reported net income; it does not affect these cash figures. What has changed recently. Revenue in the first half of 2026 was flat with a year earlier ($669 million against $675 million), but operating income fell about 22% in both the first and second quarters, and cash taxes rose. We estimate the business is now producing cash before interest at roughly $245 million a year, down about a quarter from 2025. The latest full year's per-share cash earnings rose about 6%. Our central case nonetheless starts below that: its first year is roughly 23% lower, because two straight quarters of falling profits on flat revenue are already reported. How we treat the cycle. This is one of the most cyclical businesses in energy. From the 2014 oil-price collapse through 2021, too many vessels chased too little work, day rates fell below operating costs, and Tidewater lost money for years and restructured in 2017. Across the full 2018-2025 cycle the middle year produced about $1 a share of cash before interest and the average year about $1.90, against $6.30 in 2025. We therefore do not assume today's earnings last. Each case also lets the fleet wear out. The company depreciates its vessels over lives of up to 20 years from construction. Our judgement is that they keep working somewhat longer, to about 25 years. There is no new building programme in the filings, so the fleet's earning power is assumed to shrink steadily over the following decade or so. Central case: earnings keep easing from the current level ($200 million in 2027, $160 million in 2028). Then a moderate downturn of the kind this industry has had about once a decade cuts cash generation to $30-60 million a year in 2029-2031, roughly the middle year of the last cycle. After that the business recovers to about $100 million a year, the average of the last full cycle. From 2032 that figure shrinks as vessels retire, reaching zero by 2045. The business is worth about $929 million ($18.53 a share). It owes $667 million: $650 million of 9.125% notes due July 2030 plus $17 million of vessel loans. Because those notes carry a high coupon for four more years and half a year's interest was accrued, we count them at about $768 million. Against that sits $614 million of cash, of which about $514 million is more than the business needs to operate. Net debt is therefore about $254 million ($5.08 a share), leaving about $13.45 a share. Bear case: a repeat of the 2015-2021 bust. Profits fall in 2027, cash generation is near zero in 2028, and the business loses $20-30 million a year before interest from 2029 to 2032, similar to Tidewater's own results in 2018-2021. Recovery to only $50 million a year follows, while the fleet retires faster, gone by 2042. In this case the July 2030 notes fall due in the trough: cash would have fallen to roughly $550 million, short of the $650 million owed. The company would have to refinance on poor terms or issue shares. The business is worth about $227 million against net debt of about $254 million, so the company would owe roughly $27 million more than it is worth (minus $0.55 a share). Shareholders would be left with essentially nothing, as happened in 2017. Bull case: the tight supply of vessels that lifted day rates from 2022 to 2025 persists. Cash generation recovers to about $270-290 million a year through 2030, still below the 2024-2025 level, with only a brief two-year dip in 2031-2032. Ships keep working to about 28-30 years, so the fleet is not gone until about 2049. The business is worth about $2.45 billion; less the same $254 million of net debt, that is about $43.73 a share. Growth credited: none. No case counts on fleet expansion, new acquisitions or rising day rates. Acquisitions have been large, one-off bets (Solstad cost $594 million in cash in 2023), not a small, repeatable programme. Acquiring or building replacement ships would cost new capital, so it is not counted either. Margin-of-safety price. We are not confident in the earnings level. The company has swung from heavy losses to strong profits within three years, and profits are falling again now. The worst plausible outcome is a multi-year bust that starts before the 2030 notes mature. The balance sheet today roughly balances cash against debt, so the company would likely survive a bust that starts in 2029 or later. A bust starting in 2027, or cash spent on buybacks or acquisitions before one (the company spent $90 million on buybacks in 2025), would leave shareholders with little, as in 2017. The ships are hard assets, but their resale value collapses in exactly the years it would be needed. The things we are most likely to be wrong about are when the downturn comes, how long the vessels keep working and whether vessel supply stays tight. An early downturn takes the shares to about zero. Longer vessel lives add a few dollars a share. Persistent tightness is the bull case. The company pays no dividend, so the return during the holding period comes from the cash the business builds. In the central case that is roughly $6-7 a share after interest over the next two and a half years, before the downturn it assumes. At $7 a share, that interim cash would equal most of the price. If the shares then came to reflect the central case's remaining value, the central case implies about 25% a year if that took three years, and about 20% if it took closer to four. That margin is what is needed against a roughly one-in-ten chance of losing nearly everything. Above $7, an early downturn would wipe out the return before the cash arrived, so the margin-of-safety price is $7. Earlier analysis. Our previous figures for this company were built on a different basis and are not comparable. Alongside the $650 million notes, the company has a $250 million revolving credit line maturing in April 2030.
