Chesapeake Energy Corporation Announces Mandatory Conversion of 5.00% Preferred Stock (Series 2005)

OKLAHOMA CITY, Apr 16, 2010 (BUSINESS WIRE) --Chesapeake Energy Corporation (NYSE:CHK) today announced that it will convert all 5,000 shares of its outstanding 5.00% Cumulative Convertible Preferred Stock (Series 2005), par value $0.01 per share, into Chesapeake Energy Corporation Common Stock, par value $0.01 per share, on May 3, 2010 (the “Mandatory Conversion Date”).

On the Mandatory Conversion Date, the 5.00% Cumulative Convertible Preferred Stock (Series 2005) will be automatically converted into a number of shares equal to $100.00 divided by the lesser of the conversion price then in effect (anticipated to be $25.55) and the average of the closing prices of our common stock for the five trading days ending on April 29, 2010. Dividends on the preferred stock will cease to accrue on the Mandatory Conversion Date. Cash will be paid in lieu of fractional shares of common stock. No payment or adjustment will be made upon conversion of the preferred stock for accrued dividends with respect to the preferred stock or for dividends with respect to the common stock issued upon conversion.

From and after May 3, 2010, the preferred stock remaining outstanding will be deemed to be no longer outstanding and all rights of the holders with respect to such preferred stock will terminate, except the right to receive the whole shares of common stock issuable upon conversion and cash in lieu of any fractional shares, as described above.
