NO CLASS HAS YET BEEN CERTIFIED IN THE ABOVE ACTION. UNTIL A CLASS IS CERTIFIED, YOU ARE NOT REPRESENTED BY COUNSEL UNLESS YOU RETAIN ONE. YOU MAY CHOOSE TO DO NOTHING AT THIS POINT AND REMAIN AN ABSENT CLASS MEMBER.

According to the lawsuit, Biogen and certain of its executive officers and directors misrepresented the financial benefits that Biogen would receive from the sale of its drug TECFIDERA. TECFIDERA is one of Biogen’s most important drug products. On multiple occasions during the first half of 2015, the defendants projected 2015 revenue growth between 14% and 16% over 2014. Specifically, the market was told that “TECFIDERA will represent the largest contributor to [Biogen’s] overall revenue growth.”

However, on July 24, 2015, Biogen revealed a correction to its earlier announced revenue growth guidance, decreasing its projected growth by half “based largely on revised expectations for the growth of TECFIDERA.” Consequently, the trading price of Biogen common stock dropped from a closing price of $385.05 on July 23, 2015 to close at $300.03 per share on July 24, 2015, a loss of more than 22%, on extremely heavy trading volume.
