PubMatic, Inc. (PUBM): fair value, margin of safety and Wheel Score
Technology · Software - Application · United States · Speculative / Distressed
Is PUBM undervalued?
PUBM closed at 17.64 on 16 Oct 2026 against a GLS average fair value of 18.61 - 5.2% below fair value, which our screens read as "fairly priced". 1 of 2 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.
Only 2 of the nine models produced a value (DCF, 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 PUBM 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 PUBM
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 | 12.17 | -31% | Present value of the projected free cash flows, discounted at the cost of capital |
| 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 | 25.06 | +42% | 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) | 2.31 | -87% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 19.89 | +13% | Analysts' average 12-month price target. Not in the average |
Quality and financial health
Financial health is average - PUBM 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 4.7 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 -4.7%, ROE -5.5%, ROA -2.1% - with debt at 0.17 times equity and a free-cash-flow yield of 5.8%.
PubMatic, Inc. 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 Reportable 100% (quarter Q2 FY2026).
Institutional ownership scores 8/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 5 / 9 | ROIC | -4.7% |
|---|---|---|---|
| GLS Moat | 4.7 / 10 | ROE | -5.5% |
| Debt / equity | 0.17 | ROA | -2.1% |
| Free-cash-flow yield | 5.8% | Payout ratio | 0% |
| Institutions | 8 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 45: Weak
PUBM 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 15/25, Health 11/20, Moat 7/15, Premium 13/20, Stability 11/20. 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 89% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (13 of 20) because volatility this high usually comes with a reason. Chain open interest is 23,743 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 590k shares a day on a market cap of $804M, with a beta of 1.56 - 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 11 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 15 / 25 | 5% margin of safety | |
| Health | 11 / 20 | Piotroski 5/9 | |
| Moat | 7 / 15 | moat 4.7/10 | |
| Premium | 13 / 20 | implied volatility 89% | |
| Stability | 11 / 20 | 590k shares/day, $804M cap, beta 1.56 |

The next earnings report is due on 9 Nov 2026 (after the close), 24 days away; a 30-45-day put sold today would expire after it, which is worth weighing against the premium.
