Financial Overview

• Electric Utility segment earnings increased $34.9 million as a result of a) GMO utility operations earnings; b) improved operating
results at KCP&L; and c) lower taxes at KCP&L

• Other segment earnings decreased $11.3 million primarily as a result of increased interest from the equity units issued in May and
various favorable impacts reflected in 2008 earnings

• Loss from the discontinued operations of Strategic Energy, which Great Plains sold in June 2008, was about $15 million less than
2008

• An approximate 50% increase in average number of shares outstanding since the second quarter of 2008 resulted in $0.13 per
share dilution

• Increased Electric Utility segment earnings of $25.3 million attributable to a) GMO utility operations earnings; b) higher AFUDC at
KCP&L; and c) lower taxes at KCP&L

• Increased Other segment earnings of $25.4 million due primarily to GMO non-utility operations’ contribution, primarily from a tax
benefit related to an audit settlement, and various unfavorable impacts included in 2008 results

• Loss in 2009 related to a tax accrual for the discontinued operations of Strategic Energy compares unfavorably to earnings from
discontinued operations for the first half of 2008

• Increase of 38.1 million average dilutive shares outstanding resulted in $0.20 per share dilution
