The company said at an investor meeting in Cologne, Germany, that it expects to earn 58 cents to 62 cents a share in the second quarter, in line with analysts' estimate of 59 cents a share.

"Trading patterns in Europe continue to shift, with centralized warehousing and manufacturing creating more opportunities for small-package growth and increased demands for supply-chain services. The planned expansion of the European Union can only help this trend," UPS International President David Abney said in a press release. Shares of UPS were up slightly in early afternoon trading to $63.28.
