Apellis Pharmaceuticals (APLS) intrinsic value and fair value
The calculator grows one of Apellis Pharmaceuticals's per-share figures (earnings, free cash flow, revenue, book value or dividends) for a few years, puts an exit multiple on it, and discounts the result back at the yearly return you want. The answers below use its starting inputs for APLS; this is analysis, not investment advice.
Frequently asked
What is Apellis Pharmaceuticals's (APLS) intrinsic value?+
With Intrinsiqq's starting inputs, Apellis Pharmaceuticals's fair value is about $7.17 a share, based on its earnings per share. That assumes earnings per share of $1.09 grows about 5.0% a year for 5 years, the stock then trades at 8.3 times earnings, and you want a 10.0% yearly return. On its other figures: free cash flow $2.36, revenue $17.39. Every input can be changed on the page; the result is a model, not a forecast.
Is Apellis Pharmaceuticals overvalued?+
At $3.10, the price is 57% below that fair value of $7.17, and buying at today's price would return about 30.0% a year if those inputs hold. Whether that is cheap or dear depends on whether you believe the growth and the exit multiple, which is what the calculator lets you test. This is analysis from SEC filings, not investment advice.
What growth does the Apellis Pharmaceuticals valuation assume?+
Earnings per share grows about 5.0% a year to start, a default, because there is too little history. The exit multiple starts at a default.
What is a good margin of safety for Apellis Pharmaceuticals?+
A margin of safety is the cushion you want below the fair value before buying, in case the inputs are wrong. The calculator uses 25%, which puts the buy-below price at $5.38. Less predictable businesses deserve a wider cushion, or a higher desired return.
