Yahoo Inc.'s recently resurgent stock retreated by more than 5 percent Friday amid fears that a setback in a lucrative partnership with ATT Inc. will undercut the anticipated gains from an overhaul of the Web portal's advertising platform. The selloff was triggered by an unconfirmed report in The Wall Street Journal that ATT wants to stop giving Yahoo a slice of the subscriber fees from a 6yearold cobranding agreement to sell Internet access in most of the country. If ATT gets its way, Yahoo would have to be satisfied with whatever money it could make by selling its own online products, such as digital music or matchmaking services, to subscribers of the joint service.

A Yahoo statement included that same language and dismissed the Wall Street Journal report as "based on rumor and speculation." It added, however, that the companies were discussing ways to expand their partnership to include ATTowned Cingular Wireless. Investors drew their own negative conclusions. Yahoo shares fell $1.59, or 5.2 percent, to close at $29.12 on the Nasdaq Stock Market. Before Friday's downturn, Yahoo's stock had climbed by 20 percent this year, rebounding from a horrible 2006 performance. That reflected Wall Street's widespread belief that Yahoo will prosper from a monthold upgrade to its formula for linking ads to search requests. But a reshuffling of the ATT Rosetta Stone Greek deal would deliver a substantial blow. Under the current terms of the contract, ATT is believed to pay Yahoo $200 to $250 million annually, accounting for more than 25 percent of the $798 million in total fees that the Internet powerhouse collected last year. Most of Yahoo's revenue which totaled $6.4 billion last year comes from advertising. Compounding the pain, Yahoo's profit margins on the ATT partnership are much higher than on many of its other services because the telecommunications carrier handles most of the heavy lifting. Standard Poor's analyst Scott Kessler estimated the reported revisions in the ATT deal would reduce Yahoo's annual profit by $30 million to $70 million, or 2 to 5 cents per share. Analysts expect Yahoo to earn nearly $780 million, or 54 cents per share, this year. The damage to Yahoo could be worse if its other major Internet access partners Verizon Communications Inc., BT Group PLC and Rogers Communications Inc. follow ATT's lead when they renegotiate their contracts. Yahoo hasn't publicly disclosed the length of the contracts with its Internet access partners, but the ATT alliance reportedly expires in April 2008. Friday's news woke up many investors who thought Yahoo had turned the corner after slowing revenue growth and competitive challenges posed by increasingly popular Internet hangouts like contributed to last year's 35 percent decline in Yahoo's stock price. An improved advertising system known as "Panama" unveiled Feb. 5 after a three month delay has become the foundation for Yahoo's turnaround hopes. The upgrade is supposed to begin boosting Yahoo's profit in the second half of this year a prospect that now looks shakier, Kessler said. "A lot of people have gotten scared again and are starting to realize that they have been pinning their hopes on the promise of something that is still uncertain," he said.
