Zuora exceeded fiscal Q4 sales and met profit expectations, with similar characteristics for its Q1 guidance, "though prudent annual subscription guidance was a touch shy," Jefferies analyst John DiFucci tells investors in a research note. Zuora's business metrics were strong, and while subscription growth of 35% decelerated modestly it was against the most difficult comp this year, the analyst adds. He continues to believe the "subscription economy" will drive a growth rate of at least 25%-30% over the next five-to-ten years for Zuora. DiFucci keeps a Buy rating on the shares with a $35 price target
