What stands out

Operating margin is thin at 5.52%. Limited cushion if revenue slows or costs rise, not the profile of a wide-moat business.

What's changing

Revenue up 28.5% YoY with margins expanding 26.6pp.

What deserves caution

Even for strong businesses, today's 3x P/E means the stock needs to keep delivering. There's no margin of safety if growth disappoints.

Valuation context

2.7x earnings, 10.1x FCF. The multiple is below average. Either the market is pricing in deterioration you should investigate, or there's genuine value here.

Is Apellis Pharmaceuticals (APLS) overvalued?

At a P/E of 2.7 and a price-to-free-cash-flow of 10.1, Apellis Pharmaceuticals (APLS) trades below a two-stage DCF intrinsic value of about $7.91 per share, so at $2.99 the stock looks undervalued (165.0% below estimated intrinsic value). A high multiple is not the same as overvalued: fast-growing, high-quality businesses can deserve a premium. See the general approach in how to tell if a stock is overvalued.

On quality, Apellis Pharmaceuticals scores 83/100 on Intrinsiqq's quality scorecard (a high-quality business on these measures), weighing growth, margins, returns on capital, share count, and balance-sheet strength.

Frequently asked

What is Apellis Pharmaceuticals's fair value?+

Intrinsiqq's two-stage DCF estimates an intrinsic value of about $7.91 per share for APLS, projecting its recent free cash flow forward with a growth rate that fades toward a long-run rate and discounting it back to today. Applying a 25% margin of safety gives a more conservative fair-value entry around $5.93. At today's $2.99, that puts the stock about 165.0% below estimated intrinsic value. The result is sensitive to the growth and discount-rate inputs, so it is best to run conservative, base and optimistic cases. You can adjust all of them yourself with the sliders on the DCF tab.

Is Apellis Pharmaceuticals a high-quality business?+

Apellis Pharmaceuticals scores 83 out of 100 on Intrinsiqq's quality score, a weighted blend of 7 metrics each scored 0 to 100, which makes it a high-quality business on these measures. Recent fundamentals include a 14.9% operating margin and a 43.2% return on invested capital. The score weighs revenue and free-cash-flow growth, operating margins, return on invested capital, share-count change, and balance-sheet strength, all computed from SEC filings, not opinion. Because valuation only means something relative to quality, the full metric-by-metric breakdown is on the quality scorecard.

Is Apellis Pharmaceuticals a good stock to buy right now?+

That depends on valuation and quality together, not either alone. APLS currently trades below its estimated intrinsic value and scores 83/100 on quality (high-quality). A cheap price is only a bargain if the business is durable, and a premium can be justified by genuine quality, so the two questions, "is it cheap?" and "is it good?", only make sense side by side. Read the valuation against the quality scorecard, run the DCF on your own assumptions, and decide for yourself. This is analysis from SEC filings, not investment advice.
