TECO Energy amends and extends agreement to sell TECO Coal

TAMPA, December 24, 2014

TECO Energy Inc. (NYSE:TE) today announced that it has entered into an agreement with Cambrian Coal Corporation to modify the terms of the Securities Purchase Agreement (SPA) dated as of October 17, 2014, related to the sale of TECO Coal. Under this amendment, the SPA is subject to termination by either party if the specified closing conditions are not met by February 20, 2015, rather than Dec. 31, 2014, as originally specified.

TECO Energy CEO John Ramil stated, “This agreement best positions us to execute our strategy to exit the coal business in as expeditious a manner as is reasonable, while still receiving fair value for TECO Coal.”

The specifics of the amendment were filed with the SEC in the form of a Current Report on Form 8-K on this date.
