On June 28, 2016, Regency Centers Corporation. (the “Company”) physically settled a portion of its forward sale agreement dated March 17, 2016 (the “Forward Sale Agreement”) with JPMorgan Chase Bank, National Association (the “Forward Purchaser”) by delivering an aggregate of 1,850,000 shares of the Company’s common stock. Upon physical settlement of such portion of the Forward Sale Agreement, the Company received net proceeds of approximately $137.5 million, after deducting the underwriters’ discount and before deducting estimated offering expenses. 1,250,000 shares of the Company’s common stock may still be physically settled under the Forward Sale Agreement prior to June 23, 2017.

As previously announced, on March 17, 2016, the Company priced an offering of its common stock, par value $0.01 per share (the “Offering”). In connection with the Offering, the Company entered into the Forward Sale Agreement and an underwriting agreement dated March 17, 2016 (the “Underwriting Agreement”) by and among the Company, the Forward Purchaser, the Forward Seller (as defined therein) and J.P. Morgan Securities, LLC, as an underwriter (the “Underwriter”). Pursuant to the Underwriting Agreement, the Forward Seller borrowed and sold to the Underwriter an aggregate of 3,100,000 shares of the Company’s common stock. The Forward Sale Agreement relates to the forward sale by the Company of a number of shares of common stock equal to the number of shares of common stock borrowed and sold by the Forward Seller pursuant to the Underwriting Agreement.

The Offering is described in the prospectus supplement of the Company, dated March 17, 2016, together with the related prospectus dated March 4, 2014. The description of the Underwriting Agreement and the Forward Sale Agreement set forth above is qualified in its entirety by reference to the Underwriting Agreement and the Forward Sale Agreement, which are filed as Exhibits 1.1 and 10.1 respectively, to the Company’s Current Report on Form 8-K filed on March 21, 2016.

On June 28, 2016, the Company issued a press release announcing the partial settlement. A copy of the press release is filed as Exhibit 99.1 to this report and is incorporated herein by reference.

The information in this item shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference into any disclosure document relating to the Company, except to the extent, if any, expressly set forth by specific reference in such filing.
