Great Plains Energy and Westar Energy Shareholders Approve Merger at Special Shareholder Meetings

KANSAS CITY, Mo. & TOPEKA, Kan.–(BUSINESS WIRE)–Westar Energy, Inc. (NYSE: WR) and Great Plains Energy Incorporated
(NYSE: GXP), the parent company of Kansas City Power & Light (“KCP&L”),
today announced at their respective shareholder meetings that
shareholders overwhelmingly approved the proposals necessary for the
merger between the two companies. More than 90 percent of the shares
voted at each company approved the transaction.

“We are excited about today’s approval from shareholders of both Great
Plains Energy and Westar Energy. This vote indicates that both
companies’ shareholders believe in our combined ability to create a
stronger regional energy provider, positioned to better serve all of our
customers,” said Terry Bassham, chairman, president and chief executive
officer of Great Plains Energy and KCP&L. “This new combined company
will ensure we keep ownership of our utility assets in our region to
grow local economies.”

“Customers and shareholders will benefit by combining Westar Energy and
Great Plains Energy into a strong Midwest utility,” said Mark Ruelle,
president and chief executive officer of Westar Energy. “Our geography
and history of partnership position us to bring efficiencies and savings
by joining our operations. We continue to make progress toward
completing the transaction in the first half of 2018.”

Westar Energy and Great Plains Energy announced a revised transaction in
July 2017 after the Kansas Corporation Commission denied the companies’
original request to combine in April. This revised agreement involves no
transaction debt, no exchange of cash, and is a stock-for-stock merger
of equals, creating a company with a combined equity value of
approximately $15 billion.

The merger is expected to help maintain reliable, low cost energy for
the company’s 1 million Kansas customers and nearly 600,000 customers in
Missouri. Additionally, with one of the largest renewable energy
portfolios in the nation, the new combined company will be a clean
energy leader, supplying nearly half of its retail sales from
emissions-free electricity.
