MILWAUKEE – Integrys Holding, Inc. (Integrys), successor by merger to Integrys Energy Group, Inc. and wholly owned subsidiary of WEC Energy Group, Inc., announced today that it has notified the New York Stock Exchange (NYSE) of its intention to voluntarily delist its 6.00% Junior Subordinated Notes due 2073 (Notes) from the NYSE. Following the delisting, Integrys intends to deregister the Notes from registration with the U.S. Securities and Exchange Commission.

On June 29, 2015, Integrys became the successor obligor under the Notes as a result of its merger with Integrys Energy Group, Inc., the original issuer of the Notes. In connection with the acquisition, the common stock of Integrys Energy Group was delisted from the NYSE, and as a result the Notes are the only securities of Integrys currently listed on the NYSE. Taking into account the small number of holders and low trading volume of the Notes, Integrys determined to delist the Notes because the administrative costs and burdens associated with maintaining the listing exceed the benefits.

After the delisting, holders of the Notes will continue to deal with and receive their interest payments through the trustee, U.S. Bank National Association. Integrys has not arranged for the listing and/or registration of the Notes on another national securities exchange or quotation system.
