Interpretation of Financial Ratios
In 2024, Biogen’s financial ratios present a mixed picture. The net margin (16.9%) and ROE (14.5%) are reasonable, yet the P/E ratio (13.7) suggests undervaluation in comparison to the industry. However, the declining current and quick ratios indicate potential liquidity concerns. The interest coverage ratio (9.9) is strong, signaling good debt management, but the lack of dividend yield should be noted by income-focused investors.
Evolution of Financial Ratios
Over the past five years, Biogen’s financial ratios have shown volatility, particularly in profitability metrics such as net margin and ROE. While the P/E ratio has fluctuated significantly, indicating market perception changes, the gradual improvement in debt metrics is a positive trend that reflects improved financial stability.
Distribution Policy

This approach is typical for companies in a high-growth phase, focusing on expanding their product pipeline rather than returning cash to shareholders. However, BIIB does engage in share buybacks, signaling a commitment to enhancing shareholder value. Overall, the absence of dividends aligns with a long-term value creation strategy, provided the reinvestment yields sustainable returns.

Should You Buy Biogen Inc.?
Biogen Inc. has a strong net margin of 16.87% alongside a return on invested capital (ROIC) of 4.37%, which is slightly below its weighted average cost of capital (WACC) of 4.37%. The company’s flagship products continue to perform well, but it faces recent competitive pressures and a bearish long-term trend.
Given that the net margin is positive but the ROIC is equal to the WACC, combined with a bearish long-term trend and recent seller volumes, I recommend waiting for more favorable conditions. It may be prudent to monitor for a bullish reversal and a return of buyer volumes before considering Biogen Inc. for a long-term investment strategy.
Specific risks for Biogen include intense competition in the biopharmaceutical sector, potential supply chain disruptions, and the need for continued innovation to maintain market share.
