The package delivery company, whose shares fell nearly 3 percent, said the next two quarters would be extremely difficult, but added that there were there were signs that the pace of economic decline had slowed.
We remain optimistic that we will see quarter-over-quarter economic improvement later this calendar year, Chief Executive Fred Smith said in a statement.
FedEx forecast earnings per share of 30 cents to 45 cents for the current quarter. Analysts were expecting 70 cents.
The company said its loss had widened to $876 million, or $2.82 a share, in the fourth quarter ended May 31 from $241 million, or 78 cents a share, a year earlier.
Excluding previously announced charges of $1.2 billion from two units, the company reported a profit of 64 cents a share.
Wall Street analysts on average had expected earnings per share of 51 cents, according to Reuters Estimates.
The charges stem from a decline in the fair value of home office supply chain Kinko's Inc, which FedEx bought in 2004 and is now called FedEx Office, and Watkins Motor Lines, a trucking company acquired in 2006 and now known as FedEx National LTL. Both units have been hit by the recession.
NO FULL-YEAR PROFIT OUTLOOK
Like its main rival, United Parcel Service Inc
As the U.S. recession has dragged on, package volumes at both companies have suffered.
FedEx said stringent cost-cutting had mitigated the impact of the recession on its results.
While cost control came in stronger than expected ..., the fact remains FedEx has more operating leverage than the vast majority of freight companies, so (there is) nowhere to hide in the current perfect economic storm, UBS analyst Rick Paterson wrote in a note for clients. But cost control will only take FedEx so far... with stagnant pricing, no material productivity opportunities given the network is already optimized, and market share initiatives unable to materially offset the brutal business cycle.
FedEx reported quarterly revenue of $7.85 billion, down more than 20 percent from $9.87 billion a year earlier.
At this time we do not have enough visibility into the economic recovery and jet fuel prices to provide a meaningful annual earnings forecast, said Chief Financial Officer Alan Graf. However, we believe that FedEx will be poised for growth in our fiscal second half, as our many cost-saving initiatives gain traction and the economy begins to improve.
When fuel prices go up, the extra expense hits FedEx's results in the short term. The company charges customers a fuel surcharge, which lags real-time prices by up to two months, so in the medium term it recoups those costs.
Graf said on a conference call with analysts that the company expected the U.S. economy to return to growth in the first quarter of calendar year 2010.
In morning New York Stock Exchange trading, FedEx shares were down 2.8 percent at $50.
