Yahoo has been making acquisition after acquisition in an attempt to turn things around and transition into a mobile-focused business, and now Foursquare could be in the company’s sights. If today’s report is true, then Yahoo could be trying to bite off one of its biggest deals yet.

Yahoo! Inc. Said To Be Talking Buyout With Foursquare

However, another report released shortly after the first report claims that there aren’t negotiations going on between Yahoo and Foursquare.

Yahoo to buy Foursquare for $900m?

According to Ingrid Lunden and Jordan Crook of TechCrunch, their sources told them that Yahoo is in talks to buy Foursquare, possibly for as much as $900 million. Foursquare is known for Swarm, its location-based check-in app.

One of TechCrunch’s sources claimed that the deal had been done but that the two companies are still finalizing the details. However, the website added that some of its sources had heard nothing about negotiations between Yahoo and Foursquare.

Not long after TechCrunch’s report, CNBC tweeted that David Faber’s sources claim the two are not in talks about a buyout.

Not the first time for this rumor

Of course this isn’t the first time we’ve heard speculations that Yahoo might buy Foursquare. Also it seems as if Yahoo CEO Marissa Mayer may have had her eye on Foursquare for quite some time. According to TechCrunch, she was keeping an eye on both Foursquare and Tumblr while she was at Google. After taking the helm at Yahoo, Mayer orchestrated the company’s acquisition of Tumblr.

TechCrunch suggested that what they’ve been hearing about talks between Yahoo and Foursquare could actually be an indication that Foursquare is talking with other potential acquirers. However, the site also stated that its sources specifically mentioned Yahoo as a suitor.

As of this writing, shares of Yahoo were up 0.12% to $45.59 per share.
