Standard & Poor's Tuesday cut its unsolicited rating outlook on Yahoo! to negative from stable, citing prospects for poor revenue growth and higher costs for acquiring traffic.
The rating firm currently has a BB+ rating on the tech company, which has trailed its rivals amid high-level defections and growing doubts over the management's ability to turn a corner.
An unsolicited rating is a credit rating assigned at the initiative of the credit rating agency, not when an issuer requests for it. Still, the warning did enough to push Yahoo! Japan shares down by nearly 2 percent in Tokyo.
"We could lower our rating on Yahoo if the company's competitiveness in its display or search advertising businesses continues to decline and it is not able to reverse the negative operating trends affecting earnings before interest, tax, depreciation and amortization (EBITDA)," S&P said in a statement.
