Updated from Jan. 6DoubleClick ( DCLK) shares rose 8% early Friday after the marketing tools company boosted fourth-quarter guidance. The New York-based company said late Thursday that revenue for the quarter ended Dec. 31 would be boosted by better-than-expected results from its TechSolutions segment, which helps companies manage email and search engine advertising, among other functions. With Techsolutions revenue expected to be $6 million to $7 million higher than previously expected, the company is expecting fourth-quarter revenue to be in the range of $81 million to $82 million, up from the prior guidance range of $72 million to $77 million. Analysts surveyed by Thomson First Call had been expecting revenue to amount to $76 million. The company says it now expects earnings per share in the fourth quarter, on the basis of generally accepted accounting principles, to amount to either 6 cents or 7 cents, compared to analysts' expectations of 3 cents. The new number includes a 1-cent reduction in EPS based on new accounting rules covering convertible notes. DoubleClick's shares, which fell 17 cents to close at $7.40 Thursday, gained 60 cents in late trading upon release of the forecast and held those gains early Friday. Throughout 2004, DoubleClick disappointed analysts by making financial forecasts below analysts' expectations.
