  • Biogen investors can join this case to be notified about potential loss recovery.
Case Details:

On November 8, 2023, Biogen's Q3'23 results included negatively revised EPS guidance for FY 2023. On this news, $BIIB fell 5.67% losing $2B+ in shareholder value.

On January 8, 2024, Biogen's CEO walked back prior expectations of AD-treatment drug Legembi sales.

Due to this news, $BIIB fell 4.17% losing $1B+ in shareholder value on January 11, 2024.

On February 6, 2024, news reports emerged on challenges with the launch of Leqembi.

$BIIB fell 2.04% losing $729M+ in shareholder value on February 7, 2024.

Then, on February 13, 2024, Biogen Q4'23 and FY 2023 results missed consensus estimates for EPS and revenue. At subsequent conference call CEO disclosed Leqembi patients numbers way below goal.

On this news, $BIIB fell 7.39% losing $2.6B+ in shareholder value on February 13, 2024.

Finally, when Biogen disclosed receiving a subpoena from the DOJ related to Company's foreign operations, as well as providing similar information to the SEC, $BIIB fell 2.61%, losing $860M+ of shareholder value on February 14, 2024.

Considering all the representations, investors have reasons to suspect Biogen of serious setbacks in its corporate governance spanning several years.
