Biogen Inc. (BIIB) Stock Analysis 2026

This chart shows how BIIB's revenue flows through to profit. Each row deducts a layer of costs: first the direct cost of making products/services (Cost of Revenue), then operating expenses like marketing and R&D, then taxes. What remains at the bottom is net income — the actual profit shareholders own. High gross and net margins indicate a business with strong pricing power and efficiency.

Biogen Inc. trades at a trailing P/E of 38.74x, generates $1.27B in free cash flow, runs a debt/equity ratio of 44.33, and converts shareholder equity into profit at a 4.6% return on equity.
