What Is Apellis Pharmaceuticals' Investment Narrative?

For Apellis to make sense in a portfolio, you have to believe its complement franchise can support a durable, profitable business after years of volatility. The recent jump in Apellis shares, helped by stronger Empaveli momentum and analyst upgrades, reinforces the near term revenue story but does not fundamentally change the core catalysts: execution on Empaveli’s label expansion, ongoing uptake of SYFOVRE in geographic atrophy and disciplined spending to sustain profitability after the Q3 2025 inflection to positive earnings. What the new data and commentary do change is the tone around risk: concerns about a sluggish Empaveli ramp now look less acute, while valuation and concentration in a small number of products stand out more clearly as the issues to watch if expectations keep rising with the share price.

However, there is one concentration risk here that shareholders should not ignore. Apellis Pharmaceuticals' shares have been on the rise but are still potentially undervalued. Find out how large the opportunity might be.
