ValueClick Inc. shares fell nearly 9 percent Wednesday morning, a day after the company said second quarter net income jumped 40 percent and announced an acquisition.

After the markets closed on Tuesday, the Westlake Village online advertising company announced a definitive agreement in which Dotomi, a Chicago “intelligent display” marketing company, will become a wholly owned subsidiary.

Analysts valued the deal at $295 million, which will be split between 55 percent cash and 45 percent common stock.

It expects to generate more than $80 million in revenue this year. ValueClick anticipates the deal will be accretive on an adjusted operating basis next year.

Separately, the company reported second-quarter net income of $16.9 million (21 cents per share), compared with $12 million (15 cents) in the same period a year earlier. Revenue rose 26 percent to more than $126 million.

Excluding one-time expenses, adjusted net income was $22.4 million (28 cents). Analysts surveyed by Thomson Reuters on average expected per-share-profit of 20 cents on revenue of $121 million.

“Our momentum continued in the second quarter, as our investments to expand our growth profile and addressable markets continued to pay off,” said Chef Executive Jim Zarley in a statement.

In guidance for the current third quarter, ValueClick said it expects adjusted net income of 27 to 28 cents per share and revenue of $128 million to $130 million. The Wall Street consensus is for adjusted net income of 21 cents per share on revenue of $129 million.
