According to the SEC's complaint, filed in the U.S. District Court for the Northern District of California, Matthew Panuwat, the then-head of business development at Medivation, a mid-sized, oncology-focused biopharmaceutical company, purchased short-term, out-of-the-money stock options in Incyte Corporation, another mid-cap oncology-focused biopharmaceutical company, just days before the Aug. 22, 2016, announcement that Pfizer would acquire Medivation at a significant premium. Panuwat allegedly purchased the options within minutes of learning highly confidential information concerning the merger. According to the complaint, Panuwat knew that investment bankers had cited Incyte as a comparable company in discussions with Medivation and he anticipated that the acquisition of Medivation would likely lead to an increase in Incyte's stock price.
