Exponent, Inc. (EXPO): fair value, margin of safety and Wheel Score
Industrials · Engineering & Construction · United States · Defensive
Is EXPO undervalued?
EXPO closed at 72.28 on 16 Oct 2026, more than 30% above the GLS average fair value of 38.35. Only 0 of the 9 models that produced a value sit above the price. By our models the shares are priced well beyond what the filed earnings, cash flow and book value support; the Sunday Scan drops names like this at the "below fair value" rule.
The 9 models disagree widely: Graham Number gives 17.47 while Graham Growth gives 70.00. A spread that wide means the average is sensitive to which methods you trust; the model table below shows where each one lands, and the Quote page lets you switch any of them off.
The nightly engine files EXPO under Defensive: a low beta, a dividend and positive earnings.
Nine valuation models for EXPO
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 | 54.10 | -25% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 17.47 | -76% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 70.00 | -3% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 26.05 | -64% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 19.19 | -73% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 63.79 | -12% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 50.95 | -30% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | 18.10 | -75% | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend |
| EPV | 25.47 | -65% | Earnings power value: current EPS capitalised at 9% with no growth |
| Zombie (liquidation) | 0.1957 | -100% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 72.00 | -0% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
On financial health EXPO scores 7/9 (Piotroski): most of the nine tests - positive earnings and cash flow, falling debt, rising margins and turnover - are passed, which is the kind of balance sheet a wheel trader is happy to be assigned. The GLS Moat score is 6.8 out of 10: a ten-year record that is consistent in some of the metrics the score tracks (revenue, earnings, margins, cash flow, returns on capital) and patchy in others.
Returns on capital are high - ROIC 22.4%, ROE 27.2%, ROA 13.1% - with debt at 0.21 times equity and a free-cash-flow yield of 3.2%.
The dividend yield is 1.70% at a payout ratio of 55%; 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 Engineering And Other Scientific 87%, Environmental And Health 13% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 5/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 7 / 9 | ROIC | 22.4% |
|---|---|---|---|
| GLS Moat | 6.8 / 10 | ROE | 27.2% |
| Debt / equity | 0.21 | ROA | 13.1% |
| Free-cash-flow yield | 3.2% | Payout ratio | 55% |
| Institutions | 10 / 10 | Insiders · Congress | 5 · 5 / 10 |
Wheel Score 60: Fair
EXPO scores 60 out of 100 on the Wheel Score (Fair band, 50-64): a usable but unremarkable fit for the wheel strategy. The parts: Value 0/25, Health 16/20, Moat 10/15, Premium 20/20, Stability 14/20. Value (0/25) is where the points are missing.
Implied volatility is 42% 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. Chain open interest is thin - 1,757 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 455k shares a day on a market cap of $3.4B, with a beta of 0.70 - a low beta, so day-to-day moves are smaller than the market's; the Stability part of the Wheel Score gives that 14 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 0 / 25 | -88% margin of safety | |
| Health | 16 / 20 | Piotroski 7/9 | |
| Moat | 10 / 15 | moat 6.8/10 | |
| Premium | 20 / 20 | implied volatility 42% | |
| Stability | 14 / 20 | 455k shares/day, $3.4B cap, beta 0.70 |
