Craig-Hallum analyst Jason Kreyer notes that AT&T (T) announced the acquisition of AppNexus, a deal rumored to be valued at $1.6B. The analyst sees this deal having a ripple effect through the ad tech landscape, particularly as it relates to the publisher's end of the spectrum. In his view, Rubicon Project (RUBI) stands to benefit substantially by the removal of an aggressive competitor, with thousands of publishers and hundreds of millions of advertising spend likely searching for a new home. Further, Kreyer now sees the integration of AppNexus under the AT&T umbrella as the number one growth catalyst for Rubicon over the next 12-18 months as a substantial volume of ad impressions likely search for a new home. He reiterates a Buy rating and $4 price target on Rubicon's shares.
