Digi International Inc. (DGII): fair value, margin of safety and Wheel Score
Ticker symbol DGII · Technology · Communication Equipment · United States · Growth
Is DGII undervalued?
DGII closed at 72.58 on 5 Nov 2026, more than 30% above the GLS average fair value of 44.69. Only 2 of the 8 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 "below fair value" Wheel Trade Filter keeps names like this under 70.
There is a wide gap between Lynch (10.81) and Payback Time (108.21). 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, DGII is clearly faster-growing than it is cheap, so the nightly engine files it under Growth (value score 20, growth score 46, out of 100).
Nine valuation models for DGII
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 | 42.55 | -41% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 22.95 | -68% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 31.86 | -56% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 10.81 | -85% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 47.33 | -35% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |
| 10 Cap | 79.46 | +9% | Owner's earnings (operating cash flow less maintenance capex) capitalised at 10% |
| Payback Time | 108.21 | +49% | Eight years of compounded free cash flow: the price at which the business pays for itself |
| DDM | - | - | Dividend discount model: next year's dividend ÷ (10% − 3% growth); needs a dividend; no value tonight |

| Zombie (liquidation) | -4.11 | -106% | Current assets less all liabilities, per share: the balance-sheet floor. Not in the average |

Quality and financial health
Digi International Inc. scores 6 of 9 on the Piotroski F-score: a middling result that passes the "Piotroski 6 or more" Wheel Trade Filter. Some of the nine tests on profitability, leverage and efficiency are failed, so the accounts are worth a look before selling a put on the name. A GLS Moat score of 4.7/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, so the Moat part of the Wheel Score contributes little.
Returns on capital are moderate - ROIC 5.0%, ROE 6.4%, ROA 4.4% - with debt at 0.28 times equity and a free-cash-flow yield of 4.9%.
Digi International 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 Product 64%, Service 36% (quarter Q3 FY2026).
Institutional ownership scores 10/10, insider activity 4/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 6 / 9 | ROIC | 5.0% |
|---|---|---|---|
| GLS Moat | 4.7 / 10 | ROE | 6.4% |
| Debt / equity | 0.28 | ROA | 4.4% |
| Free-cash-flow yield | 4.9% | Payout ratio | 0% |
| Institutions | 10 / 10 | Insiders · Congress | 4 · 5 / 10 |
Wheel Score 35: Weak
With a Wheel Score of 35 Digi International Inc. sits in the Weak band. It fails filter 1, options that actually trade - options too quiet (272 open interest, 68 a day); and filter 3, below fair value - trades 62% above our fair value; Value (weak) is its weakest part.
Implied volatility is 53% on the near-the-money contracts 20-60 days out - inside the 35-60% sweet spot the Wheel Score rewards most: enough premium to be worth selling, not so much that the risk is unpaid. Chain open interest is thin - 272 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 472k shares a day on a market cap of $2.8B, with a beta of 1.00; 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 (272 open interest, 68 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 | Fails | trades 62% above our fair value |
| 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 | Weak | 62% above fair value | |
| Premium | Strong | implied volatility 53% | |
| Moat | Fair | moat 4.7/10 | |
| Health | Good | Piotroski 6/9 | |
| Red Flags | Strong | Red Flags score 90/100 | |
| Option trading | Weak | 68 contracts a day, 272 open interest | |
| Stability | Fair | beta 1.00, $2.8B company |

A stock that fails any filter stays under 70; 70-84 is Good, 85 and above is Prime. The Sunday Scan is the top 10 that pass, sorted by Wheel Score.
