reported a soft first quarter and guided toward a weak second quarter.

The news had little effect on DoubleClick shares, which jumped 17% during regular trading Thursday on rumors that the company is close to being acquired by a private equity firm. In a postclose conference call, CEO Kevin Ryan played coy, saying only that a "review of strategic options is ongoing and therefore we will not be commenting on these issues or press reports at this time."

First-quarter results showed a loss of $917,000, or a penny a share, reversing the year-ago profit of $7.7 million, or a nickel a share. DoubleClick recorded $76.3 million in revenue, up from $68 million in the same period year before. The company said the loss was largely due to charges related to its review of strategic options.

Analysts polled by Thompson First Call had forecast a 2-cent profit on revenue of $74 million

DoubleClick said it expects a roughly break-even second quarter on revenue of around $74 million. Analysts had seen profits of 4 cents a share on revenue of $75.9 million.

In regular action, the Web marketer's stock soared $1.21 to $8.56 on speculation that it is on the

verge of being sold to San Francisco-based buyout firm Hellman & Friedman for $1.2 billion.
