The company’s stock was halted twice, before closing up more than 12%. PayPal, meanwhile, closed down nearly 5%.PayPal had discussed acquiring the company for a potential price of around $70 a share, which would value Pinterest at about $39 billion, according to Bloomberg.Pinterest, which allows users to create and share image boards, went public in April 2019, where it was valued at just more than $10 billion. Its market cap today sits at around $37 billion.Andrew Jeffrey, Trust Securities analyst, told CNBC last Thursday that he was skeptical of a PayPal-Pinterest merger.”A move to make another online deal, even in social media, just doesn’t make a lot of sense long term,” Jeffrey said, adding that PayPal needs to monetize in the physical world.”Unless the company can monetize off of e-com (instore) with Venmo, we think it’s growth is ultimately going to revert toward e-com growth and that kind of deceleration is not currently priced into the stock,” he added.
