Fair Value models

Bear $141.16 Fair Value $201.65 Bull $262.16

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 9 months old). Earnings retained since then ($4.07 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. 98/100

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.

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.

+25.2%

Earnings growth per share plus dividend.

Earnings per share, growth per year+25.2%

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.

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.27% → 33%

Growth Forecast

Price in line with expectations

The price assumes less growth than the company has delivered so far and about what 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).

+7.6%

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.

+6.5%

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 +5.1% a year for the price and +4.1% for the forecasts.

Forecast 2026 (sales)+8.3%

Our models discount Qualys Inc at 8.8 %: a base by market capitalisation (mid), damped by beta 0.61, 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 Qualys Inc that is +7.6 % per year a year over ten years, using the same discount rate (8.8 %) and the same formula as our fair value.

How much growth has Qualys Inc (QLYS) delivered so far?

Over the past 5 years revenue at Qualys Inc grew +13.0 % a year. The price currently implies +7.6 % 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 Qualys Inc (QLYS)?

The free-cash-flow yield on the price is 4.52 %: that much free cash flow Qualys Inc produces per unit of market value. When it exceeds the discount rate of our models (8.8 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.

What is the intrinsic value of Qualys Inc (QLYS)?

Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For Qualys Inc it is $201.65 per share (as of Sep 23, 2026), against a price of $184.79. It is the blended result of 24 valuation models (cash flow, earnings, asset, dividend).

Is fair value the same as the market price of QLYS?

No. The price is what the market pays today ($184.79); the fair value is what the company's own numbers justify ($201.65). For Qualys Inc the two are $16.86 per share apart. That gap is exactly why we show both numbers side by side.

What is the P/E ratio of QLYS?

Qualys Inc trades at a price-to-earnings ratio of 27.5 (as of Sep 23, 2026). A P/E on its own says little: it compares the price with ONE year of profit, while our fair value of $201.65 is built from several models across several years. Other multiples: PEG 6.0, P/B 11.9, P/S 9.8, EV/EBITDA 26.3.
