IPO fever is heating up. Video conferencing firm Zoom became one of the latest companies to catch it, filing paperwork on Friday to go public. Its prospectus paints a picture of a financially healthy company, which given the popularity of Zoom’s product, maybe shouldn’t be surprising. Zoom’s revenue doubled last year to $330.5 million, producing a net profit of $7.6 million. Investors are hot for subscription enterprise firms right now, so demand for Zoom stock is sure to be strong. Based on a conservative multiple of six times revenue, Zoom should have no problem getting a valuation of $2 billion—twice its last private market valuation.
