Fourth Quarter Results

Favorable results at the electric utility segment and Integrys Energy Services drove the increase in adjusted earnings.

Electric utility segment margins increased due to the electric rate increases effective in January 2011 and fuel window impacts at Wisconsin Public Service. New fuel window rules were effective in 2011. These rules drove changes in the timing of recognition of differences between actual and projected fuel costs, which caused a positive quarter‐over‐quarter impact.

Integrys Energy Services continued to see positive results following the implementation of the strategy change. Operating expenses were lower quarter‐over‐quarter. In addition, realized retail electric margins increased due to a revised pricing strategy.

The natural gas utility segment saw a decrease in adjusted earnings caused by lower sales volumes due to warmer weather, partially offset by decoupling impacts in those jurisdictions that have decoupling.

"I am pleased with our improved adjusted earnings," said Charles A. Schrock, Chairman, President and Chief Executive Officer of Integrys Energy Group. "Our fourth quarter 2011 diluted EPS — adjusted results were up 23 percent and our full year 2011 results were up about 8 percent when compared with the same periods in 2010. This demonstrates that the execution of our business strategy is yielding anticipated financial results."

Earnings Forecast

Integrys Energy Group's guidance range for 2012 diluted earnings per share on a GAAP basis is between $3.35 and $3.55. This guidance assumes operational improvements, the availability of generation units, and normal weather conditions for 2012. At this time, Integrys Energy Group is not estimating the impact of derivative and inventory accounting activities at Integrys Energy Services and is not projecting any other special items for 2012. Diluted earnings per share — adjusted results will be provided as usual each quarter in 2012.
