Valuation

Bull case: the DCF Models group reads highest at a median of $34.48 per share, and 0 of the 24 models we run sit above the $75.30 price.

Bear case: the Earnings-Based group reads lowest at $8.32, and 24 of the 24 models stay below the price. Evidence for this calculation is medium.

Scenario range: $22.68 (bear) to $37.88 (bull), the price of $75.30 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target.

Quality & growth

The Quality Score stands at 67/100 (solid quality), in the Technology sector.

Healthy Growth: Revenue growth appears healthy and is supported by profitability and cash-flow quality.

Digi International Inc reported revenue of $430M in FY2025 versus $309M in FY2021, a compound +8.7%/yr. Reported net income was $40.8M in FY2025, compounding +40.9%/yr from FY2021.

Competitive moat

Our AI-assisted moat analysis scores the competitive advantage at 51 out of 100 (low confidence).

What moves the price

The last reported earnings sit well below what analysts expect (earnings in transition, for example after write-downs or an earnings dip); whether the stock is cheap or expensive hinges on the expected recovery actually arriving. Read the fair value with that caveat.

The share trades about 12% below its 52-week high and 113% above its 52-week low, currently above its 200-day average.

For context, the median of 10 Technology peers we cover trades at −46% fair-value upside, at −60%, DGII screens richer than that median.

Fair Value models

Bear $22.68 Fair Value $30.30 Bull $37.88
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above is their evidence-weighted blend, not the output of a single model. Based on fiscal year 2025 figures (about 12 months old). Earnings retained since then ($1.11 per share) are deliberately not added. Bear ⓘBear = the cautious scenario: the same model computed with conservative anchors (lower growth, margins and valuation multiples). Together with Bull it frames a plausible valuation range, not a price target.BaseBull ⓘBull = the optimistic scenario: the same model computed with favourable anchors (higher growth, margins and valuation multiples). Together with Bear it frames a plausible valuation range, not a price target. Evidence ⓘEvidence = how well-backed THIS model's estimate is for this stock (0–100): how complete and reliable its input data are, and how well the model fits the company. The final Fair Value is an evidence-weighted blend, so better-evidenced models count more. Green ≥70, amber 50–69, grey below 50.

Revenue & earnings trend

Growth Quality ⓘGrowth is valuable only when reinvestment earns attractive returns (Aswath Damodaran): sustainable growth depends on return on capital, reinvestment and efficiency. Basis: total company revenue over the periods shown on the cards (3Y/5Y/all years), not per share, so a merger can show up as a growth jump; per-share earnings growth is in the value-creation card. 78/100
Revenue growth appears healthy and is supported by profitability and cash-flow quality.
Revenue growth 1 year
+1.5%
Revenue growth 3 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+3.5%
Revenue growth 5 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+9.0%
Start year 2020 (pandemic). Over 10 years: +7.3% a year
Revenue growth 37 years ⓘMeasures the company's TOTAL revenue from reported annual statements: compound average growth per year (CAGR) from the fiscal year 3, 5 or N years back to the most recent comparable fiscal year. Not per share: buybacks do not change this number, and a merger can appear as a growth jump. Per-share growth (which does include buybacks) is in the value-creation card.
+11.2%
What shareholders gained per year (last 5 years) ⓘWhat the business itself delivers per year: earnings growth per share plus the dividend yield. This is what you get IF the market keeps valuing the stock the same way: it contains no assumption about the market changing its mind. Computed per share, so buybacks count and a merger does not pass as growth. For a company that pays no dividend it is pure earnings growth per share. Period: earnings growth per share as CAGR over the last 5 reported fiscal years (annual statements), plus the current dividend yield. The start value is the median of the three years around the start, so a single crisis year (a pandemic or a write-down) does not distort the rate. Basis: adjusted.
+32.4%
Earnings growth per share plus dividend.
Earnings per share, growth per year+32.4%
Dividend (yield on the price)0.0%
Pace: 5 vs 10 years ⓘTwo data points, not a trend model: earnings growth per share over the last 5 fiscal years against the last 10. Labelled "steady" when both rates are within 3 percentage points of each other, otherwise picking up or flattening. Shown only when ten years of history exist.28% vs 15%, picking up
Profit margin 2020 to 2025 ⓘOperating margin then vs now, from reported annual statements. A falling margin after a boom year is the classic peak-earnings signal: the growth rate then leans on an inflated base.4% → 13%
Start year 2020 (pandemic)

Growth Forecast

A lot of optimism in the price
The price assumes more growth than the company has delivered so far and more than analysts expect.
What the price assumes ⓘThis turns our valuation around: instead of asking what the share is worth, it asks what growth the current price requires. It uses the cash the company keeps after all spending (free cash flow), the same discount rate as our models, five years of growth, then slowing evenly to 2 % a year by year ten. Compared with the analysts' sales forecasts extended to the same five years (at least three analysts, for context only, it does not enter the Fair Value): within 3 percentage points counts as "in line" (amber), below that little optimism (green), above that a lot of optimism (red).
+15.9%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect ⓘAnalysts publish sales forecasts for the next two fiscal years. For the years after that, growth slows evenly to 2 % a year by year ten (2 % is the long-run rate our models use). Projected years are marked as such.
+9.5%
Yearly sales growth analysts expect, extended to five years.
After inflation (USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about +13.2% a year for the price and +6.9% for the forecasts.
Forecast 2026 (sales)+21.2%
Forecast 2027 (sales)+7.8%
Projected 2028 (sales)+7.1%
Projected 2029 (sales)+6.4%

Over the last 5 years revenue grew +9.0 % per year. As of Sep 24, 2026.
What discount rate (WACC) does the fair value of DGII use?
Our models discount Digi International Inc at 9.6 %: a base by market capitalisation (mid), damped by beta 0.96, country premium for USA. The same rate applies in all 26 models.
What is a reverse DCF?
A reverse DCF turns the usual calculation around. Instead of deriving a value from assumptions, it takes today's price as given and asks: what free-cash-flow growth would a company have to deliver for exactly this price to be fair? The result is not a forecast but the expectation already priced in. For Digi International Inc that is +15.9 % per year a year over ten years, using the same discount rate (9.6 %) and the same formula as our fair value.
How much growth has Digi International Inc (DGII) delivered so far?
Over the past 5 years revenue at Digi International Inc grew +9.0 % a year. The price currently implies +15.9 % per year free-cash-flow growth a year. Comparing the two shows how much confidence is in the price: if it demands more than has been delivered, the business has to accelerate for the maths to work.

What is the free cash flow yield of Digi International Inc (DGII)?
The free-cash-flow yield on the price is 3.71 %: that much free cash flow Digi International Inc produces per unit of market value. When it exceeds the discount rate of our models (9.6 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.
What is the intrinsic value of Digi International Inc (DGII)?
Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For Digi International Inc it is $30.30 per share (as of Sep 24, 2026), against a price of $75.30. It is the blended result of 24 valuation models (cash flow, earnings, asset, dividend).

Is fair value the same as the market price of DGII?
No. The price is what the market pays today ($75.30); the fair value is what the company's own numbers justify ($30.30). For Digi International Inc the two are $45.00 per share apart. That gap is exactly why we show both numbers side by side.
How much is Digi International Inc worth?
The market values Digi International Inc at about $2.8B (market capitalisation, as of Sep 24, 2026). Per share that is $75.30; our models calculate a fair value of $30.30 per share.

Our models span a range for Digi International Inc: cautious scenario $22.68, base $30.30, optimistic $37.88 per share (as of Sep 24, 2026, price $75.30). The range comes from different growth and margin assumptions, not from analyst opinions.
What is the P/E ratio of DGII?
Digi International Inc trades at a price-to-earnings ratio of 66.6 (as of Sep 24, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of $30.30 is built from several models across several years. Other multiples: PEG 0.8, P/B 4.5, P/S 6.0, EV/EBITDA 28.7.
What is the PEG ratio of DGII?
The PEG ratio of Digi International Inc is 0.83 (P/E divided by earnings growth, as of Sep 24, 2026). That is below 1, so growth is priced more cheaply than the earnings multiple alone suggests.
How solid is the balance sheet of Digi International Inc (DGII)?

Is it still worth investing in stocks now?
The global stock market currently sits 14.1 % above its aggregate fair value. Digi International Inc itself currently trades above fair value. An expensive market is no reason to stay out and no reason to buy everything at once: keep a broad savings plan running, buy single stocks only with money you can do without, and hold part of your money liquid while the market is high. The full picture including sectors is on is it worth investing now.

What should I pay attention to with Digi International Inc right now?

Broken into its drivers: revenue per share +4.4 %, EBIT margin +12.8 %, tax rate +0.6 %, residual (interest, one-offs) −6.9 %. The four rates multiply to the earnings growth rate, they do not add up.
