Even though it topped estimates in its first-quarter report, FedEx (NYSE: FDX) saw the market send its shares down to a nearly two-year low after the company slightly lowered its full-year earnings outlook because of the global slowdown.

Did the market overreact? Let’s dig deeper.

Weak global health
FedEx posted revenue of $10.52 billion for the quarter, up 11% from a year ago. Earnings per share rose 22% to $1.46, beating market expectations by a penny. The company benefited from better pricing, though it saw a decline in volumes.

The sluggish global economy has been hurting FedEx and rival United Parcel Service (NYSE: UPS). With weak consumer confidence, even airline companies such as Delta Air Lines (NYSE: DAL) and United Continental (NYSE: UAL) are witnessing slower cargo shipment. As a result, FedEx has reduced its full-year earnings-per-share outlook by $0.10 to a range of $6.25 to $6.75 a share.

FedEx is already suffering from declining demand and volume in the U.S. and Asia, partly because of consumers' reduced preference for electronic products and other gadgets, especially from China. The sorrow doesn’t end here, either. The company's operating expenditure grew to $9.78 billion, an 11% increase over last year, mainly because of a whopping 40% year-on-year increase in fuel costs. So far, FedEx has managed to offset these problems by raising prices.

However, because of slow global growth, customers are shifting to slower shipping -- and therefore cheaper -- options like ground shipping, rather than more costly overnight express services. This trend may help explain the 3% fall in daily average package volume in FedEx Express and a 5% increase in FedEx Ground.

An overall increase in revenue per package helped the company remain solidly profitable. Revenues grew prominently across all areas of the business.

The Foolish bottom line
Though the slow-moving economy is not favorable to FedEx, it still has the potential to grow reasonably well. This dividend-paying company has done a good job with its pricing strategy and is trading cheap because of the global economic uncertainty.
