Core Laboratories N.V. (CLB): fair value, margin of safety and Wheel Score
Energy · Oil & Gas Equipment & Services · United States · Blend
Is CLB undervalued?
Core Laboratories N.V. (CLB) closed at 9.78 on 16 Oct 2026. The GLS average fair value - the simple average of the 9 valuation models that produced a positive number - is 12.50, so the price sits 22% below it. 5 of the 9 models value the shares above the current price. A margin of safety between 10% and 30% is where most of the Sunday Scan candidates come from.
There is a wide gap between DDM (0.5886) and Graham Growth (29.72). 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.

|---|---|---|---|
| DCF | 13.59 | +39% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 8.25 | -16% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 29.72 | +204% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 12.99 | +33% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 21.73 | +122% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
Core Laboratories N.V. 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 Sunday Scan's "6 or more" rule with room to spare. A GLS Moat score of 2.8/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are moderate - ROIC 6.9%, ROE 11.2%, ROA 5.1% - with debt at 0.62 times equity and a free-cash-flow yield of 2.4%.
The dividend yield is 0.41% with a payout ratio of 8% - a small yield that leaves most of the earnings in the business. Revenue comes mainly from Service 76%, Product 24% (quarter Q2 FY2026).
Institutional ownership scores 10/10, insider activity 10/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 8 / 9 | ROIC | 6.9% |
|---|---|---|---|
| GLS Moat | 2.8 / 10 | ROE | 11.2% |
| Debt / equity | 0.62 | ROA | 5.1% |
| Free-cash-flow yield | 2.4% | Payout ratio | 8% |
| Institutions | 10 / 10 | Insiders · Congress | 10 · 5 / 10 |
Wheel Score 76: Good
With a Wheel Score of 76 - the Good band - Core Laboratories N.V. clears the Sunday Scan's "70 or higher" rule. The parts: Value 22/25, Health 18/20, Moat 4/15, Premium 20/20, Stability 12/20; Moat (4/15) scores lowest.
Implied volatility is 58% 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 - 1,603 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 802k shares a day on a market cap of $449M, with a beta of 1.14; the Stability part of the Wheel Score gives that 12 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 22 / 25 | 22% margin of safety | |
| Health | 18 / 20 | Piotroski 8/9 | |
| Moat | 4 / 15 | moat 2.8/10 | |
| Premium | 20 / 20 | implied volatility 58% | |
| Stability | 12 / 20 | 802k shares/day, $449M cap, beta 1.14 |
