Yahoo!

(YHOO)

posted fourth-quarter pro-forma earnings of 19 cents a share before items, beating the

First Call/Thomson Financial

27-analyst estimate of 15 cents and the year-ago 4 cents, excluding items. The company said its revenue totaled $201.1 million, up from $91.3 million in last year's fourth quarter, and that its December traffic averaged 465 million page views a day, compared with an average of 167 million the year before. Yahoo! also announced a 2-for-1 stock split effective Feb. 14.

In a report,

Merrill Lynch

analyst Henry Blodget wrote that while revenue and earnings "did not beat the highest estimates, the strength of the fundamental business drivers -- audience, commerce, advertising and communications -- suggests a strong year ahead." Blodget maintained his buy rating on the stock and gave the company an "A" grade for the quarter.
