Citi analyst Walter Pritchard expects DocuSign to report billings upside when reporting Q3 results on December 6. His estimates for subscription revenue and billings remain ahead of consensus and guidance. The analyst predicts subscription revenue growth of 37% year-over-year and total billings growth of 29%. Further, he thinks the estimates for the company's Q4 look conservative. A "clean" quarter should remind investors of DocuSign's "attractive drivers" and "under-appreciated" growth, Pritchard tells investors in a pre-earnings research note. He keeps a Buy rating on the shares with a $70 price target.
