Disney (DIS) is going to be a large customer for the content delivery networks given the ramp of Disney+, ESPN+ and Hulu, Piper Sandler analyst James Fish tells investors in a research note. The analyst views the one hour of average Disney+ watching, the quick ramp of paid subs, exit subs across all three services, coming original content, less than 5% content delivery networks cost and future launches of the over-the-stop services into new countries as "strong positives" for content delivery networks. Fastly (FSLY) has the most relative exposure to over-the-top within its business, while Akamai (AKAM) will get the largest traffic share among the CDN vendors, according to Fish. Further, the analyst says he recently learned that F5 Networks' (FFIV) NGINX unit has a utility-based enterprise license agreement with Disney+ that should enable it to also benefit as the streaming service grows. In addition, coronavirus fears may also drive more content delivery network business as consumers stay at home more, argues Fish. He believes the early success of Disney+ is a "strong positive" for Akamai, Fastly and F5 and continues to recommend owning all three stocks.
