AnaptysBio Inc. (NASDAQ:ANAB) shares are up on Monday as the company celebrates a favorable ruling from the Delaware Chancery Court regarding its Collaboration Agreement with Tesaro.

The court on Friday dismissed Tesaro’s anticipatory breach claim, which has contributed to a 12.64% increase in share price.

GSK Plc (NYSE:GSK) acquired Tesaro in December 2018 for approximately $5.1 billion (4.0 billion British pounds).
