2008 First Quarter Summary

In the first quarter of 2008, Union Pacific reported operating income of $788 million compared to $719 million in first quarter of 2007, a 10 percent improvement.

* The Company’s freight revenue grew 11 percent in 2008 to a quarterly best of $4.1 billion. All six business groups posted record first quarter revenue, while three groups, Agricultural, Chemical and Energy, set all-time marks. The main driver of revenue growth was an 11 percent increase in average revenue per car (ARC), which reached a quarterly record of $1,738 per car in the first quarter 2008. Core pricing gains and greater fuel cost recovery each contributed approximately half of the overall ARC increase.

* Business volumes in the first quarter of 2008, as measured by total revenue carloads, were flat at 2.3 million.

* The Railroad’s 2008 average quarterly fuel price, including transportation and taxes, was up 47 percent to $2.84 per gallon compared to $1.93 in 2007.

* Driven by higher fuel prices, first quarter 2008 operating ratio was slightly higher at 81.5 percent versus 81.3 percent in 2007.

* The Company’s fuel consumption rate, as measured by gallons per thousand gross ton-miles, was a first quarter-best rate of 1.283 versus 1.302 in the first quarter 2007.

* The effective tax rate in the first quarter of 2008 was 35.5 percent reflecting a state tax law change, which resulted in a one-time after tax earnings increase of $16 million.

* The Company repurchased nearly 3.3 million common shares at an average share price of $123.67 in the first quarter of 2008. The year-over-year reduction in the weighted average diluted shares outstanding drove a 5 percent increase in fully diluted earnings per share.
