Item 2.01 Completion of Acquisition or Disposition of Assets.

On July 1, 2016 (the “Closing Date”), Emera Inc., a Nova Scotia corporation (“Emera”), completed its previously announced acquisition of TECO Energy, Inc. (“TECO Energy”) through a merger (the “Merger”) of Emera US Inc., a Florida corporation and indirect wholly owned subsidiary of Emera (“Merger Sub”), with and into TECO Energy pursuant to the Agreement and Plan of Merger, dated as of September 4, 2015, by and among TECO Energy, Emera, and Merger Sub (the “Merger Agreement”). As a result of the Merger, TECO Energy became an indirect, wholly owned subsidiary of Emera effective at approximately 8:00 a.m. Eastern Daylight Time (the “Effective Time”) on the Closing Date.

Pursuant to the Merger Agreement, at the Effective Time each share of TECO Energy common stock issued and outstanding immediately prior to the Effective Time (other than shares of common stock of TECO Energy owned by TECO Energy as treasury stock, if any, shares of TECO Energy common stock owned by TECO Energy’s wholly owned subsidiaries, if any, and shares of TECO Energy common stock owned directly or indirectly by Emera or Merger Sub, if any) were cancelled and converted automatically into the right to receive $27.55 in cash, without interest and less any applicable withholding taxes (the “Merger Consideration”). Pursuant to the terms of the Merger Agreement, each share of common stock of Merger Sub issued and outstanding immediately prior to the Effective Time was converted into one share of the common stock of TECO Energy, as the surviving corporation in the Merger, and constituted the only outstanding shares of TECO Energy, as the surviving corporation in the Merger, as of the Effective Time.

Pursuant to the Merger Agreement, at the Effective Time:

In addition, effective as of the opening of trading on the New York Stock Exchange (“NYSE”) on the Closing Date, the shares of TECO Energy common stock, which traded under the symbol “TE”, were suspended from trading on the NYSE. On the Closing Date, TECO Energy requested that the NYSE file with the Securities and Exchange Commission an application on Form 25 to delist the TECO Energy common stock from the NYSE and deregister the TECO Energy common stock under Section 12(b) of the Securities Exchange Act of 1934, as amended.
