The global spending slowdown has hurt eBay's ability to attract buyers to its auction sites and the strengthening of the U.S. dollar also crimped profit from its overseas operations.

"Clearly we've been operating in an almost unprecedented external environment," Chief Executive John Donahoe told analysts. "There is no doubt eBay was impacted by the macroeconomy."

Analysts said the company's first-quarter view, which came in well below Wall Street estimates, was a bleak sign. Jeffrey Lindsay of Bernstein Research called it "a pessimistic guidance for 2009."

"The real story is they are guiding down a lot," he said.

Net profit in the fourth quarter, usually eBay's strongest due to holiday sales, fell to $367 million, or 29 cents per share, from $531 million, or 39 cents per share, a year earlier.

Excluding charges from a 10 percent staff reduction last fall and other restructuring costs, earnings per share were 41 cents, at the top of eBay's own forecast, and beating the Wall Street view of 39 cents, according to Reuters Estimates.

Total revenue fell 7 percent to $2.04 billion, below the $2.11 billion expected by Wall Street. The bulk of that was due to a 16 percent drop at its main business, which largely consists of its auction sites. Revenue rose 26 percent at Web- based telephone company Skype and 11 percent at Web payments service PayPal.

For the fiscal 2009 first quarter, eBay expects adjusted earnings of 32 cents to 34 cents on revenue of $1.8 billion to $2.05 billion. Analysts had forecast earnings per share of 40 cents.

STRUGGLE WITH AMAZON

EBay, whose shares are down 56 percent from a year ago, has faced an uphill battle trying to stimulate growth in its marketplaces unit, while confronting rivals such as Amazon.com Inc and craigslist.com.

The stock fell to $12.49 after-hours from its close of $13.28.

"There is just less velocity and less business being closed," said Martin Pyykkonen of Wunderlich Securities. "Part of it is because there is just too much fixed price revenue. Frankly, eBay is almost an inconvenient way to buy a fixed priced item."

In October, the San Jose, California-based company warned it could be hit by a grim economy curtailing consumer spending in the United States and across much of the globe. Some 53 percent of eBay sales come from abroad.

The company, which has been laying off workers while boosting its marketing efforts, has taken several steps to revive growth in auctions, including lower listing fees, coupons and better security.

Those investments weighed on operating margins, which fell in the fourth quarter to 22.3 percent from 28.7 percent a year earlier.

EBay shares, valued at 8.3 times fiscal 2009 projected earnings, are at a deep discount to Amazon at 36, Yahoo Inc at 27 and Google Inc at 14 times expected earnings.
