Fair Value models

Bear R$46.71 Fair Value R$91.27 Bull R$130.89
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. 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. 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. 59/100
Revenue is growing, but margins or cash flow do not fully confirm the trend.
Profit margin (trend) ⓘ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.
−73.4% (2022) → 11.9% (2025)
What shareholders gained per year ⓘWe only publish this rate when it is defensible. Reason: fiscal 2025 is a loss year, no rate is defined from a loss
not computed

Growth Forecast

A lot of optimism in the price
The price assumes less 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).
−5.6%
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.
−31.8%
Yearly sales growth analysts expect, extended to five years.
After inflation (figures in USD, USA: IMF forecast 2.4% a year to 2030, 3.1% from 2016 to 2025) that is about −7.8% a year for the price and −33.4% for the forecasts.
Forecast 2026 (sales)−37.5%
Forecast 2027 (sales)−37.5%
Projected 2028 (sales)−32.5%
Projected 2029 (sales)−27.6%
Projected 2030 (sales)−22.7%

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 Arrowhead Pharmaceuticals, Inc. that is -5.6 % per year a year over ten years, using the same discount rate (15.2 %) and the same formula as our fair value.

The free-cash-flow yield on the price is 13.82 %: that much free cash flow Arrowhead Pharmaceuticals, Inc. produces per unit of market value.

The full picture including sectors is on is it worth investing now.

What should I pay attention to with Arrowhead Pharmaceuticals, Inc. right now?
The price is below even our cautious bear case (R$46.71). The market is more pessimistic than our downside scenario. The model range is unusually wide (R$46.71 to R$130.89). The outcome hinges heavily on assumptions, so read the point estimate with caution. The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution. Solid quality (46/100) at a price below fair value, the discount is the argument here, not the business quality.
