Ticker symbol TS · Energy · Oil & Gas Equipment & Services · Luxembourg · ADR · Blend

Is TS undervalued?
TS closed at 55.92 on 5 Nov 2026 against a GLS average fair value of 58.92 - 5.1% below fair value, which our scans read as "fairly priced". 3 of 9 models are above the current price. There is no discount to lean on here, so the margin of safety is not the reason to look at the stock.
There is a wide gap between Lynch (10.47) and DCF (138.96). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
Ranked against every other company we cover, neither cheapness nor growth clearly wins for TS, so the nightly engine files it under Blend (value score 47, growth score 31, out of 100).
Nine valuation models for TS
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 | 138.96 | +148% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 26.65 | -52% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 51.08 | -9% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 10.47 | -81% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 52.56 | -6% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 94.41 | +69% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 89.60 | +60% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 25.60 | -54% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 40.90 | -27% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | 10.86 | -81% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 67.33 | +20% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Tenaris S.A. scores 8 of 9 on the Piotroski F-score, the nine yes/no tests of profitability, leverage and efficiency on the latest annual accounts - a strong reading that passes the "Piotroski 6 or more" Wheel Trade Filter with room to spare. On durability TS scores 6.0/10 on the GLS Moat - a middle reading; the Moat Score tab on the Quote page's Financials view shows which of the four parts hold it back.
Returns on capital are moderate - ROIC 11.3%, ROE 11.6%, ROA 9.6% - with debt at 0.03 times equity and a free-cash-flow yield of 6.1%.
The dividend yield is 3.04% at a payout ratio of 47%; for a wheel trader holding assigned shares the dividend adds to the covered-call premium, and the ex-dividend date is worth knowing before a call is sold.
Institutional ownership scores 1/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 8 / 9 | ROIC | 11.3% |
|---|---|---|---|
| GLS Moat | 6.0 / 10 | ROE | 11.6% |
| Debt / equity | 0.03 | ROA | 9.6% |
| Free-cash-flow yield | 6.1% | Payout ratio | 47% |
| Institutions | 1 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 73: Good
With a Wheel Score of 73 - the Good band - Tenaris S.A. passes all 9 Wheel Trade Filters. How it ranks: value weak, premium strong, moat good, health strong, red flags good, option trading fair, stability strong. Value (weak) is the part keeping it out of the Prime band.
Implied volatility is 54% on the near-the-money contracts 20-60 days out - inside the 35-60% sweet spot the Wheel Score rewards most: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is 7,351 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 1.4M shares a day on a market cap of $30.0B, with a beta of 0.48 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score rates that strong.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Passes | Profitable over the last twelve months - not a speculative stock, fund or note |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Passes | Piotroski F-score 6 or more out of 9 (a company with no score on file passes) |
| 5 | Can repay its debt | Passes | Long-term debt repaid from 3 years of operating cash flow or less (6 for real estate and utilities; banks and insurers are not judged on it) |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Passes | Implied volatility 25-80% (enough premium, not a lottery ticket) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Weak | 5% below fair value | |
| Premium | Strong | implied volatility 54% | |
| Moat | Good | moat 6.0/10 | |
| Health | Strong | Piotroski 8/9 | |
| Red Flags | Good | Red Flags score 82/100 | |
| Option trading | Fair | 991 contracts a day, 7,351 open interest | |
| Stability | Strong | beta 0.48, $30.0B company |
