Item 2.01.  Completion of Acquisition or Disposition of Assets.

On June 29, 2015, Wisconsin Energy Corporation (n/k/a WEC Energy Group, Inc.), a Wisconsin corporation (“Parent”), completed the previously announced mergers contemplated by that certain Agreement and Plan of Merger (the “Merger Agreement”), dated as of June 22, 2014, by and among Parent, Integrys Energy Group, Inc., a Wisconsin corporation (the “Company”), WEC Acquisition Corp., a Wisconsin corporation (“Merger Sub”) and Integrys Holding, Inc. (f/k/a GET Acquisition Corp.), a Wisconsin corporation (“Subsequent Merger Sub”).  Pursuant to the Merger Agreement, (i) Parent formed Merger Sub and Subsequent Merger Sub, which became parties to the Merger Agreement through execution of a joinder agreement, (ii) Merger Sub merged with and into the Company (the “Initial Merger”), with the Company continuing as the surviving corporation and wholly owned subsidiary of Parent (the “Initial Surviving Corporation”) and (iii) immediately following the Initial Merger, the Initial Surviving Corporation merged with and into Subsequent Merger Sub, with Subsequent Merger Sub continuing as the surviving corporation and wholly owned subsidiary of Parent (the “Subsequent Merger” and, together with the Initial Merger, the “Merger”).

At the effective time of the Initial Merger (the “Effective Time”), each share of common stock of the Company, par value $1.00 per share (“Company Common Stock”), issued and outstanding immediately prior to the Effective Time (other than shares owned by the Company or Parent) was cancelled and converted into the right to receive (i) $18.58 in cash, without interest and (ii) 1.128 validly issued, fully paid and nonassessable shares of common stock of Parent, par value $0.01 per share (“Parent Common Stock”).

At the Effective Time, each option to purchase shares of Company Common Stock, each restricted stock unit payable in shares of Company Common Stock (whether subject to performance-based or time-based vesting) and each stock unit credited to the account of any participant in the Company’s deferred compensation plan, in each case, that was outstanding immediately prior to the Effective Time, whether vested or unvested, was cancelled at the Effective Time with cash consideration to be paid therefor in accordance with the terms of the Merger Agreement.

At the Effective Time, the Company became a wholly owned subsidiary of Parent. In addition, effective as of the open of trading on the New York Stock Exchange (“NYSE”) on June 30, 2015, the shares of Company Common Stock, which trade under the symbol “TEG,” will cease trading on, and will be delisted from, the NYSE.

The foregoing description of the Merger Agreement does not purport to be complete and is subject to and qualified in its entirety by reference to the full text of the Merger Agreement, a copy of which is attached as Exhibit 2.1 to the Current Report on Form 8-K filed by Parent on June 23, 2014.

Brodsky, Albert J. Budney, and Paul W. Jones, each a former member of the board of directors of the Company, became members of the Board.
