Is Apellis Pharmaceuticals (APLS) Undervalued After Its Recent Share Price Rebound?

Apellis Pharmaceuticals (APLS) has quietly staged a rebound this month, with the stock up roughly 23% even as its past year performance remains weak, inviting a closer look at what might be changing.

See our latest analysis for Apellis Pharmaceuticals.

The 23.5% 1 month share price return has helped Apellis claw back some ground from a difficult stretch. However, the 1 year total shareholder return remains deep in negative territory, which suggests sentiment may be stabilising rather than fully turning.

If this rebound has you rethinking the sector, it could be a good moment to scan other potential opportunities across healthcare stocks and see how they compare on risk and growth.

With shares still well below past highs but trading on improving fundamentals, the key question now is whether Apellis is genuinely undervalued after a harsh reset or if the market is already pricing in the next leg of growth.

Most Popular Narrative Narrative: 32.8% Undervalued

Apellis last closed at $23.78, while the most widely followed narrative sees fair value materially higher, setting up a sharp disconnect between price and expectations.

The recent FDA label expansion for EMPAVELI into rare kidney diseases (C3G and IC MPGN), along with active plans to launch and pursue additional indications (FSGS and DGF), positions Apellis to access larger patient pools and accelerate long term topline growth, driven by the increasing prevalence of rare and age associated diseases. This is likely to result in higher future revenues and market diversification.

However, sustained patient access challenges or slower than expected SYFOVRE uptake could undermine the bullish case and force analysts to revisit growth assumptions.

Another Angle on Valuation

While the narrative suggests Apellis is 32.8% undervalued, the earnings based view tells a tougher story. At a price to earnings ratio of 66.9 times versus a fair ratio of 29.8 times and an industry average of 19.1 times, the stock screens expensive. Is the market overpaying for future growth?
