Dropbox last week quietly announced, with immediate effect, a 20% increase from $10 to $12 per month for its Individual Plus version, accompanied by a storage capacity increase and some added features, Deutsche Bank analyst Karl Keirstead tells investors in a research note. Existing Plus users will get the added features at no cost until their subscriptions come up for renewal over the next 12 months, at which time they will transition to the higher price point, the analyst points out. He believes the 20% price lift on a "popular product" improves Dropbox's average revenue per user outlook as it rolls into Dropbox financials through mid-2020. Keirstead keeps a Buy rating on Dropbox shares.
