Transocean Ltd. (RIG): fair value, margin of safety and Wheel Score
Energy · Oil & Gas Drilling · Switzerland · Speculative / Distressed
Is RIG undervalued?
RIG has a margin of safety of 65%: the stock closed at 5.58 on 16 Oct 2026 against a GLS average fair value of 16.04. 1 of the 1 valuation models that produced a number sit above the price. Our screens treat a discount this large as a strong starting point for a cash-secured put, not as a verdict - the fair value is a model output, and a wide gap can mean the models are missing something the market knows.
Only 1 of the nine models produced a value (10 Cap); the others need a dividend, positive free cash flow or positive book value the company does not have yet, so the average rests on a narrow base.
The nightly engine files RIG under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.
Nine valuation models for RIG
Each model turns the latest filed numbers into a value per share; the GLS fair value is the simple average of the ones that produce a positive number. The last two rows are shown for reference and never enter the average. The Quote page lets you switch any model off and add your own margin of safety.
| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | - | - | Present value of the projected free cash flows, discounted at the cost of capital; no value tonight |
| Graham Number | - | - | The most a defensive investor pays for the earnings and book value per share; no value tonight |
| Graham Growth | - | - | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields; no value tonight |
| Lynch | - | - | EPS × the earnings growth rate (PEG of 1), growth capped at 25%; no value tonight |
| GLS Growth | - | - | EPS compounded ten years at the blended growth rate, discounted back at 15% a year; no value tonight |
| 10 Cap | 16.04 | +187% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | - | - | Eight years of compounded free cash flow: the price at which the business pays for itself; no value tonight |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |
| EPV | - | - | Earnings power value: current EPS capitalised at 9% with no growth; no value tonight |
| Zombie (liquidation) | -4.88 | -187% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 7.00 | +25% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is average - RIG passes 5 of the nine Piotroski tests, which falls one point short of the Sunday Scan's "6 or more" rule. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is low at 1.4 out of 10, which says the ten-year record of revenue, earnings, margins and returns on capital has been inconsistent - growth and shocks rather than steady compounding.
Returns on capital are thin or negative - ROIC -21.2%, ROE -36.0%, ROA -18.6% - with debt at 0.70 times equity and a free-cash-flow yield of 14.5%.
Transocean Ltd. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from Oil And Gas Service 100% (fiscal year FY2019).
Institutional ownership scores 10/10, insider activity 8/10 and Congressional trading 10/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | -21.2% |
|---|---|---|---|
| GLS Moat | 1.4 / 10 | ROE | -36.0% |
| Debt / equity | 0.70 | ROA | -18.6% |
| Free-cash-flow yield | 14.5% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 8 · 10 / 10 |
Wheel Score 45: Weak
RIG scores 45 out of 100 on the Wheel Score, in the Weak band (under 50), capped at 45 because the engine files it as Speculative / Distressed. Value 25/25, Health 11/20, Moat 2/15, Premium 20/20, Stability 18/20. The score is not a judgement on the company; it says the price, quality and premium do not line up for selling puts on it today.
Implied volatility is 52% on the near-the-money contracts 20-60 days out - inside the 35-60% range the Wheel Score pays full marks for: enough premium to be worth selling, not so much that the risk is unpaid. The option chain is deep: 1,180,047 contracts of open interest across all expiries, which means tight fills at most strikes.
Volume runs at 57.9M shares a day on a market cap of $6.2B, with a beta of 1.41 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 18 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 25 / 25 | 65% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 2 / 15 | moat 1.4/10 | |
| Premium | 20 / 20 | implied volatility 52% | |
| Stability | 18 / 20 | 57.9M shares/day, $6.2B cap, beta 1.41 |
