Caterpillar Inc. (CAT) swung to a first-quarter loss on $558 million in restructuring charges while results at its machinery segment slumped on tumbling demand.

The heavy-machinery maker slashed its forecasts for the year, cutting its earnings forecast in half to $1.25 a share, below analysts' reduced average estimate of $1.77, according to Thomson Reuters. Caterpillar is now looking for revenue of $31.5 billion to $38.5 billion, compared with the prior view of $36 billion to $46 billion.

Its shares, which are down two-thirds since May, fell another 4.9% premarket to $29 even as the quarter's results handily topped expectations.

Caterpillar expects the global economy to contract 1.3% and remain in recession for most of the year, amid continued tight credit. Though the rate of decline appears to be moderating, the company expects further drops, despite government stimulus plans that are expected to boost construction spending later this year.

The company reported a net loss of $112 million, or 19 cents a share, compared with year-earlier net income of $922 million, or $1.45 a share, a year earlier. Excluding restructuring charges, the latest quarter would have had a 39-cent profit.

Net sales decreased 22% to $9.23 billion.

Analysts polled by Thomson Reuters most recently were looking for earnings of 4 cents on revenue of $8.54 billion.

Machinery sales fell 29% and engine sales dropped 8%.

The infrastructure and commodities boom powered Caterpillar for roughly five years - helping it more than double its annual revenue from 2002 to 2007 - but collapsed late last year. Overseas sales offset a slumping U.S. housing construction market early in 2008, but late in the year a pullback in commodities prices and global demand hit results at Caterpillar and rivals such as Komatsu Ltd.(KMTUY) of Japan and Deere & Co.

Caterpillar is shedding nearly 25,000 jobs, in addition to other cost cutting moves, such as pay cuts, plant closings and shortened workweeks, though it has managed to maintain its dividend.
