Common questions

How much does the Biogen Securities Litigation Settlement pay?
The total settlement fund is $18.9M. Actual amounts depend on how many valid claims are filed — most settlements divide a fixed fund pro rata, so a higher claim rate means a smaller individual check. An "up to" figure is a cap, not a guarantee.
What is the claim deadline for the Biogen Securities Litigation Settlement?
The claim deadline is September 24, 2026. Filing is free and is done on the official settlement website at biogensecuritieslitigation.com.
Do I need proof of purchase for the Biogen Securities Litigation Settlement?
Yes. This settlement asks for documentation supporting your claim — a receipt, an account record, or the notice you were sent. Check the official settlement website for exactly which documents are accepted.
Is the Biogen Securities Litigation Settlement notice real, or a scam?
Strategic Claims Services is the settlement administrator for this case. Claims are filed at biogensecuritieslitigation.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
How long until I get paid from the Biogen Securities Litigation Settlement?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. The final approval hearing for this case is set for September 29, 2026; no payments can be issued before a settlement receives final approval.
What happens if I do nothing?
You receive no payment, and in most class actions you also give up the right to sue Biogen Inc. separately over these same claims. To keep that right you must opt out (exclude yourself) by August 25, 2026.
