, an Internet advertising firm, said Friday that quarterly revenues will fall short of Wall Street's expectations by about 25%.

The Westlake Village, Calif. company's shares closed unchanged at $8.56.

The company said revenue for the third quarter will be between $9.5 million and $10 million, while analysts had predicted revenue would exceed $12 million.

"This is further confirmation that there's a dramatic shift taking place," said Jordan Rohan, analyst for

. The firm co-managed ValueClick's initial public offering in March, and Rohan rates the shares buy. "There are competitors out there accepting very low prices for their inventory," he said.

expect the company will report a break-even quarter. In a telephone interview, Kurt Johnson, the company's chief financial officer, said those earnings predictions, as well as estimates of a $1.2 million operating loss, could be affected by currency fluctuations. The company has been starting international operations.

Johnson said he does not expect to turn a profit until the first quarter of 2001, back from previous predictions of a profit in the fourth quarter 2000. But he added that the company, which charges its clients based on the number of clicks on their advertisements, has maintained its prices and upheld gross margins of 50%. "Our business model all along has been built to withstand these kinds of market conditions," he said.

Rohan and the company sought to emphasize the difference between companies like ValueClick that charge advertisers based on the number of times Web users click on their advertisements, and others that charge based on the number of times Web users see the image. But factors that have caused a slowdown in online advertising spending will affect all the companies, other analysts said.

At the other end of the chain, concerns about slowed advertising spending have caused shares of

But as funding for e-commerce companies has grown scarce, Internet companies have sought to reduce their cash burn rates, producing a dearth of advertising dollars. "We need to have traditional advertisers -- offline advertisers like
