BIIB ALERT: Levi & Korsinsky Investigates Biogen Inc. for Possible Securities Fraud Violations Ready to Announce with Confidence? New York, New York--(Newsfile Corp. - May 18, 2026) - Levi & Korsinsky notifies investors that it has commenced an investigation into Biogen Inc. ("Biogen Inc.") (NASDAQ:BIIB) concerning potential violations of the federal securities laws.

The stock fell sharply on heavy volume following the May 14 topline data release. Biogen had previously signaled confidence in its pipeline during its Q1 2025 earnings call, with management stating they expected to see data from BIIB080 in early Alzheimer's disease sometime around mid-year." The CELIA trial did not achieve statistical significance on its primary endpoint. The magnitude of the single-session decline reflected the market's reassessment of Biogen's near-term pipeline value.
