PubMatic, Inc. (PUBM): fair value, margin of safety and Wheel Score
Ticker symbol PUBM · Technology · Software - Application · United States · Class A common stock · Speculative
PUBM is PubMatic, Inc.'s Class A common stock. The classes own the same business, share the same earnings report and trade within a few cents of each other; what differs is mainly the vote each share carries - the company's annual report sets out the voting rights.
Is PUBM undervalued?
PUBM closed at 16.36 on 5 Nov 2026, 13% below the GLS average fair value of 18.75 from 2 models (1 of them above the price). That is a moderate margin of safety: the stock passes the "below fair value" Wheel Trade Filter, with room for a bigger discount on the Value part.
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 - it is losing money or its Piotroski health score is 3 or lower - 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 | 12.44 | -24% | 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 | +53% | 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 | -86% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |
| Wall St target | 19.89 | +22% | 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 "Piotroski 6 or more" Wheel Trade Filter. The Financials tab on the Quote page shows which tests fail. The GLS Moat score is 5.9 out of 10: a record that is solid on some of the four parts the score weighs (returns on capital, pricing power, lasting growth, balance sheet) and weaker on others.
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 6.3%.
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 | 5.9 / 10 | ROE | -5.5% |
| Debt / equity | 0.17 | ROA | -2.1% |
| Free-cash-flow yield | 6.3% | Payout ratio | 0% |
| Institutions | 8 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 35: Weak
PUBM scores 35 out of 100 on the Wheel Score, in the Weak band (under 50): it fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 4, financially healthy - Piotroski 5/9 (under 6); and filter 7, a premium worth selling - implied volatility 85% (over 80%); and filter 8, big enough - market cap $745M (under $1.0B), and the parts are thin too - value fair, premium fair, moat fair, health fair, red flags good, option trading fair, stability weak. 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 85%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is 9,827 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 420k shares a day on a market cap of $745M, with a beta of 1.59 - 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 rates that weak.
| 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 | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Fails | Piotroski 5/9 (under 6) |
| 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 | Fails | implied volatility 85% (over 80%) |
| 8 | Big enough | Fails | market cap $745M (under $1.0B) |
| 9 | Not a penny stock | Passes | Share price $5 or more |
| How it ranks | Rating | From | |
|---|---|---|---|
| Value | Fair | 13% below fair value | |
| Premium | Fair | implied volatility 85% | |
| Moat | Fair | moat 5.9/10 | |
| Health | Fair | Piotroski 5/9 | |
| Red Flags | Good | Red Flags score 80/100 | |
| Option trading | Fair | 2,443 contracts a day, 9,827 open interest | |
