Price A$0.5300 · Upside +24.5%
Model ⓘEach model values the company its own way (discounted cash flow, earnings, assets, dividends). The fair value above starts from their evidence-weighted blend, not from a single model. In cyclical trough or peak years, after dilution or a stock split it is adjusted afterwards, so it can sit above or below the models. 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. If a model's bull case is above four times its base value, the table shows that limit with a > sign (like the overall Bull above): beyond it no assumption holds. Coverage ⓘCoverage = 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. 59/100
Revenue is growing, but margins or cash flow do not fully confirm the trend.
Revenue growth 1 year
+74.0%
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.

Growth Forecast

Little optimism in the price
The price assumes less growth than the company has delivered so far.
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).
+6.2%
Yearly growth needed for the next five years to justify today's price.
What forecasts expect
n/a
No analyst forecast available.
Calculated on free cash flow for fiscal year 2025. Over the last twelve months it was negative, so the figure above is uncertain.
After inflation (figures in USD, USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about +3.7% a year for the price.

What growth is priced into Etherstack Plc (ESK)?
For today's price to be fair in a discounted-cash-flow model, Etherstack Plc would have to grow free cash flow by +6.2 % per year for five years (discount rate 8.7 %, then slowing evenly to 2 % perpetual growth by year ten). Over the last 5 years revenue grew +27.2 % per year. Calculated on free cash flow for fiscal year 2025. Over the last twelve months it was negative, so the figure above is uncertain. As of Nov 9, 2026.
What discount rate (WACC) does the fair value of ESK use?
Our models discount Etherstack Plc at 8.7 %: a base by market capitalisation (nano), damped by beta 0.66, country premium for Australia. 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 Etherstack Plc that is +6.2 % per year for five years, then slowing evenly to 2 % by year ten, using the same discount rate (8.7 %) and the same formula as our fair value.
How much growth has Etherstack Plc (ESK) delivered so far?
Over the past 5 years revenue at Etherstack Plc grew +27.2 % a year. The price currently implies free-cash-flow growth of +6.2 % per 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.
How fast is the sector of Etherstack Plc (ESK) growing?
The median revenue growth in the sector is +11.5 % a year. That is the yardstick for the growth priced into Etherstack Plc (+6.2 % per year): it shows whether the expectation is within the usual range or beyond it.
What is the free cash flow yield of Etherstack Plc (ESK)?
The free-cash-flow yield on the price is 5.11 % in the last fiscal year (free cash flow was negative over the last twelve months): that much free cash flow Etherstack Plc produces per unit of market value. When it exceeds the discount rate of our models (8.7 %), the business already earns more than its cost of capital demands, and the price needs little additional growth.
What is the intrinsic value of Etherstack Plc (ESK)?
Intrinsic value and fair value mean the same thing: what the business is worth on its numbers, independent of the share price. For Etherstack Plc it is A$0.6600 per share (as of Nov 9, 2026), against a price of A$0.5300. It is the blended result of 10 valuation models in 3 families (DCF Models, Multiples, Growth DCF).
Is Etherstack Plc stock overvalued or undervalued in 2026?
As of Nov 9, 2026, ESK trades below its calculated fair value: price A$0.5300, fair value A$0.6600, a gap of about +25% (undervalued). The calculation is refreshed with each new quarterly report, so the verdict can change during the year.
Is fair value the same as the market price of ESK?
No. The price is what the market pays today (A$0.5300); the fair value is what the company's own numbers justify (A$0.6600). For Etherstack Plc the two are A$0.1300 per share apart. That gap is exactly why we show both numbers side by side.

The market values Etherstack Plc at about A$76.3M (market capitalisation, as of Nov 9, 2026). Per share that is A$0.5300; our models calculate a fair value of A$0.6600 per share.

How solid is the balance sheet of Etherstack Plc (ESK)?
Balance-sheet figures for Etherstack Plc (as of Nov 9, 2026): return on equity −18.1%, debt of 0.18 per unit of equity. They feed the Quality Score of 59/100, which measures business quality independently of the share price.
How far is ESK from its 52-week high?
Etherstack Plc trades at A$0.5300, about 30% below its 52-week high of A$0.7600 and 16% above the low of A$0.4550 (as of Nov 9, 2026). Distance from the high says nothing about value: that is what the fair value of A$0.6600 is for.
Which stocks are comparable to Etherstack Plc?
From the same area (Technology) we also value SAP SE, Salesforce, Inc, Shopify Inc, ServiceNow, Inc, among others. Each of them has its own fair-value calculation on this site using the same models, so the comparison is like for like.

Is it still worth investing in stocks now?
The global stock market currently sits 13.3% above its aggregate fair value. Etherstack Plc currently trades 20% below its own fair value, and the market average says nothing about that. 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 is the share price of Etherstack Plc (ESK)?
The closing price on Nov 9, 2026 was A$0.5300. Our model-based fair value is A$0.6600, about +25% upside (undervalued). We carry closing prices from our data provider, not a live tick.
What should I pay attention to with Etherstack Plc right now?
Solid quality (59/100) at a price below fair value, the discount is the argument here, not the business quality. A fairly wide model range (A$0.4100 to A$1.05) leaves room in how you read the outcome. Evidence is limited here (fewer models, shorter history), so the fair value is a rougher estimate than usual.
