Who Is Eligible?
You may be eligible to file a claim if you:
- You purchased or acquired Biogen securities (such as common stock) during the class period defined in the settlement
- You suffered a financial loss as a result of holding or selling those securities
- You are a U.S.-based or international investor who held a qualifying position in Biogen stock during the relevant timeframe
- Institutional investors, individual retail investors, and retirement accounts may all qualify — check your brokerage records

How Much Can You Get?
The total settlement fund is $18.9 million. Your individual payout will depend on how many valid claims are submitted and the size of your recognized loss — meaning how many shares you bought, at what price, and what losses you incurred during the class period. Investors with larger positions who suffered greater losses will generally receive a higher proportion of the settlement fund. Specific per-share payment amounts are not yet publicly confirmed, so the final payout per claimant remains to be determined once all claims are reviewed. Historically, securities settlements of this size can result in payouts ranging from a few dollars to hundreds of dollars per claimant, depending on claim volume and individual loss calculations. Filing a claim is worth doing even if your expected recovery seems modest.How to File Your Claim
