JPMorgan analyst Sterling Auty says that while DocuSign's headline revenue, earnings, and cash flow were "nicely ahead" of Q1 expectations, the billings metric fell short of expectations. The analyst, however, believes the company's growth trajectory in revenue remains intact and that the billings issue is not an indication of a problem with the business. If that turns out to be the case, any pressure on the stock could turn out to be a good buying opportunity, Auty tells investors in a research note. He keeps an Overweight rating on DocuSign with an $88 price target.
