A 30% return based on the date of the post and today's closing. The stock is at just above $1.3B market. Two M&A actions, BMY, and CELG mentioned by explo and LLY buying LEXO are putting a bit of fire on the buyout candidates.
BMY and Pfizer is a maker of Eliquis and JNJ and Bayer make Xarelto. Andexxa made by Portola is an antidote for the two drugs. Eliquis is more dominant in sales, between overall markets some $12 or $13B in sales in 2019 and more with an available antidote. Now JNJ and Beyer wanted to use Xarelto in the area where Bevyxxa another Portola drug is already approved. Since BMY bought Celgene, JNJ purchase of Portola seems very logical. There is a sense that Portola can help JNJ and the perception that Xarelto has more bleeds with Andexxa. Bottom line Portola is a candidate for a buyout and JNJ seems like a potential buyer.
At 4 times of Andexxa $1B sales and perhaps $500M for Bevyxxa when fully running, $6B looks like $96 per share. This will not happen tomorrow, but there is a good potential that stock could be $70 by Q3 of this year. Good Luck.
