Sarissa Capital Management LP announced that Sarissa Capital has entered into an agreement with Innoviva, Inc. to reconstitute the entire board of directors as follows: Effective immediately Jules Haimovitz, Sarah Schlesinger, M.D. and Mark DiPaolo will be added to the Innoviva board, joining recently added Sarissa designees George Bickerstaff, III and Odysseas Kostas, M.D. Effective as of the upcoming stockholder meeting, the Innoviva board will consist of five directors: Jules Haimovitz, Sarah Schlesinger, M.D., Mark DiPaolo, George Bickerstaff, III and Odysseas Kostas, M.D. Mark DiPaolo and Odysseas Kostas, M.D. are principals of Sarissa Capital. Jules Haimovitz, Sarah Schlesinger, M.D. and George Bickerstaff, III served together on the board of directors of ARIAD Pharmaceuticals and were instrumental in the turnaround efforts at ARIAD which culminated in the sale of the company for over $5 billion last year. This outcome is the result of a proxy contest Sarissa Capital waged in connection with Innoviva's 2017 annual stockholder meeting and Sarissa Capital's necessary subsequent litigation against Innoviva.
