AT&T has changed its mind about bidding for Yahoo, and is challenging Verizon — and others — in the effort to buy the struggling internet company, Bloomberg reports.

There’s no word on how much AT&T has offered for Yahoo’s core internet assets. A second round of bids are due the first week of June.

AT&T declined to comment.

The telco had been involved in the process through its YP Holdings, which runs the company’s Yellow Pages business — now mostly a digital operation. YP wanted to merge with Yahoo. But that idea’s been scrapped, in favor of a full acquisition, according to the report.

Like Verizon, AT&T is eager to build a collection of digital assets that would appeal to mobile subscribers. Last year it bought DirecTV. It also has a 43.4% stake in Otter Media, the production venture led by former Fox exec Peter Chernin. Their digital investments include Crunchyroll, Rooster Teeth, and Fullscreen.

Verizon had been seen as the most eager bidder for Yahoo. Others in the mix include private investment firm TPG Capital; a group with former Yahoo CEO Ross Levinsohn, Bain Capital, and Vista Equity Partners; and Quicken Loans founder Dan Gilbert with investor Warren Buffett.

Bloomberg says that John Malone’s Liberty Media “has expressed interest” in buying Yahoo but “isn’t considered a likely finalist.”
