SAN FRANCISCO - 's top executives say all is well at the Internet search leader despite a rare earnings disappointment, but investors are worried something is amiss.
Concerns about how the feeble U.S. economy might affectcontributed to a nearly 20 percent decline in the company's stock during January.
Now, it looks like February will begin on a sour note. Google shares dropped by more than 6 percent from their Thursday closing price of $564.30 after the company released fourth-quarter results that missed analysts' expectations.
Precisely what caused the letdown is likely to be a matter of intense debate in the next few days.
"There is a lot to scratch my head over about in this (report),"
Jackson Securities analyst Brian Bolan said late Thursday.
"I might be up all night trying to figure it out."
Chief Executiverebuffed the notion that the economy undercut Google's growth.
"I am happy to say we have not seen a negative impact from the rumors of a future recession,"
Schmidt told analysts in a conference call.
Company co-foundersaid in an interview that the company hasn't seen evidence of the recent economic turmoil affecting its business.
"I'm very happy with things,"
"I think things are going really well."
Google earned $1.21 billion, or $3.79 per share, during the final three months of 2007. That's a 17 percent improvement over net income of $1.03 billion, or $3.29 per share, in the same period a year earlier.
It's the first time Google's quarterly profit has climbed by less than 25 percent since the Mountain View-based company went public nearly 3 1/2 years ago.
If not for stock awards given to its employees, Google said it would have made $4.43 per share — a penny below the average estimate among analysts polled by.
The earnings would have been even lower if Google hadn't benefited from an abnormally low tax rate of 25 percent in the quarter.analyst Rob Sanderson estimated Google would have earned 11 cents per share less if the company had been taxed at its more typical rate of 27 percent.
Fourth-quarter revenue totaled $4.83 billion, a 51 percent improvement over $3.21 billion in the previous year.
In a more important measure to investors, Google retained $3.39 billion in revenue after paying fees to the thousands of Web sites in the online advertising network that fuels its profits.
The net revenue missed analyst estimates by about $60 million.
Google executives said a revision in the company's formula for showing advertising links crimped the fourth-quarter results by reducing the number of revenue-generating clicks. Without providing details, the executives said Google made the change to decrease the frequency of "accidental" clicks on ads.
Total paid clicks in the fourth quarter rose 30 percent from the same period in 2006. In the first three quarters of 2007, Google's paid clicks were rising at a clip of 45 to 52 percent.
Brin and other executives also said Google didn't reap as much revenue as management envisioned from its advertising partnerships with rapidly growing online social networks like's .
Management didn't quantify the size of the shortfall, but Brin said engineers are addressing the problem.
Google has guaranteed News Corp. payments totaling $900 million during a three-year contract scheduled to end in 2010, so it can lose money if ads on MySpace aren't paying off.
Sanderson said Google's explanations made sense to him.
"I don't think much has changed at Google from yesterday to today. They are still in a sweet spot."
But Google's reassurances didn't seem to placate jittery investors worried that online advertising revenue may taper off as the United States — the world's biggest economy — teeters on the brink of recession.
Google shares rose $16.03 to finish regular trading at $564.30, then plunged $36.90 in extended trading after the fourth-quarter results came out.
Because Google generally only gets paid when Web surfers click on an advertising link, its growth could taper off if consumers become less inclined to click on ads as they curtail their spending.
But Google also could benefit if consumers become more focused on saving money during hard times, according to, the company's senior vice president of product management and marketing.
In Thursday's conference call, Rosenberg painted a scenario in which more consumers will turn to the Internet in search of the best deals — a quest that will lead them to Google and perhaps induce more revenue-producing clicks on ads.
For all of 2007, Google earned $4.2 billion, or $13.29 per share, a 37 percent improvement over $3.08 billion, or $9.94 per share, in 2006. Revenue in 2007 totaled $16.59 billion, a 56 percent increase from $10.6 billion in 2006.
