Innospec Inc. (IOSP): fair value, margin of safety and Wheel Score
Ticker symbol IOSP · Basic Materials · Chemicals - Specialty · United States · Value
Is IOSP undervalued?
At 80.65 (close of 5 Nov 2026), IOSP trades 22% under the GLS average fair value of 102.86. 4 of the 9 models that produced a value land above the price. A discount of this size counts as a positive margin of safety in every GLS scan; whether it is enough depends on the rest of the picture - the health score, the moat and the option premium below.
There is a wide gap between DDM (26.34) and Graham Growth (326.05). 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, IOSP is clearly cheaper than it is fast-growing, so the nightly engine files it under Value (value score 54, growth score 29, out of 100).
Nine valuation models for IOSP
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 | 100.01 | +24% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 84.78 | +5% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 326.05 | +304% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 142.50 | +77% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 65.54 | -19% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 75.83 | -6% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 41.32 | -49% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 26.34 | -67% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 63.33 | -21% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | 20.51 | -75% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 110.00 | +36% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Innospec Inc. scores 7 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 IOSP scores 6.3/10 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 8.5%, ROE 8.8%, ROA 6.4% - with debt at 0.04 times equity and a free-cash-flow yield of 2.1%.
The dividend yield is 2.22% at a payout ratio of 32%; 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. Revenue comes mainly from Performance Chemicals 39%, Fuel Specialties 38%, Oilfield Services 24% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 8.5% |
|---|---|---|---|
| GLS Moat | 6.3 / 10 | ROE | 8.8% |
| Debt / equity | 0.04 | ROA | 6.4% |
| Free-cash-flow yield | 2.1% | Payout ratio | 32% |
| Institutions | 10 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 47: Weak
With a Wheel Score of 47 Innospec Inc. sits in the Weak band. It fails filter 1, options that actually trade - options too quiet (35 open interest, 36 a day); Option trading (weak) is its weakest part.
Implied volatility is 34% on the near-the-money contracts 20-60 days out: enough to pass the 25-80% Wheel Trade Filter, but under the 35-60% sweet spot the score rewards most. Chain open interest is thin - 35 contracts across every expiry - so fills at a fair price are not guaranteed; a 30-45-day put may not exist at a usable strike.
Volume runs at 482k shares a day on a market cap of $2.0B, with a beta of 0.87; the Stability part of the Wheel Score rates that fair.
| Filter | Wheel Trade Filter | Result | Detail |
|---|---|---|---|
| 1 | Options that actually trade | Fails | options too quiet (35 open interest, 36 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 | Good | 22% below fair value | |
| Premium | Strong | implied volatility 34% | |
| Moat | Good | moat 6.3/10 | |
| Health | Good | Piotroski 7/9 | |
| Red Flags | Strong | Red Flags score 100/100 | |
| Option trading | Weak | 36 contracts a day, 35 open interest | |
| Stability | Fair | beta 0.87, $2.0B company |
