Twitter Closes Its Acquisition of MoPub

Twitter just announced that it has closed its acquisition of MoPub.

We first broke the news that Twitter was acquiring the company (which helps mobile publishers manage their ad inventory) back in September. An official confirmation followed soon after, though neither company confirmed the $350 million, all-stock price that we heard (a price that AllThingsD also reported).

At the time, MoPub CEO Jim Payne compared this acquisition to Google’s purchase of DoubleClick — namely, the deal that expands a company’s ad business beyond their own site. Twitter has said that it will continue operating MoPub’s existing business, which makes sense when you consider the possibility of using Twitter social data to target MoPub ads.

In the most recent amendment to its S-1, Twitter reported that MoPub saw net revenue of $6.5 million in the first six months of this year.
