On January 15, 2015, Regency Centers Corporation (the “Company”) announced that it priced an offering of its common stock, par value $0.01 per share (the “Offering”). A copy of the press release is attached as Exhibit 99.1 to this report and is incorporated herein by reference.

In connection with the Offering, the Company entered into (i) a forward sale agreement dated January 14, 2015 (the “Forward Sale Agreement”) with an affiliate of the underwriter (the “Forward Purchaser”) and (ii) an underwriting agreement dated January 14, 2015 (the “Underwriting Agreement”) by and among the Company, the Forward Purchaser, the Forward Seller (as defined therein) and Wells Fargo Securities, LLC, as an underwriter listed therein (the “Underwriter”). Under the Forward Sale Agreement, Regency has agreed to sell to the Forward Purchaser the same number of shares of Regency’s common stock sold by an affiliate of the Forward Purchaser to the Underwriter for sale in the underwritten public offering (subject to Regency’s right to elect cash settlement of the Forward Sale Agreement). In addition, on January 15, 2015 the Underwriter notified the Company that they exercised their option in full to purchase an additional 375,000 shares of common stock and the Company and the Underwriter entered into an additional forward sale agreement (the “Additional Forward Sale Agreement, and collectively with the Forward Sale Agreement, the “Forward Sale Agreements”).

In connection with the Forward Sale Agreements, the Forward Purchaser (or its affiliate) is expected to borrow from third-party lenders and sell to the Underwriter up to 2,875,000 shares of the Company’s common stock at the close of the offering.

Settlement of the Forward Sale Agreements will occur on one or more dates occurring no later than approximately 12 months after the date of the prospectus supplement relating to the offering. Upon any physical settlement of the Forward Sale Agreements, the Company will issue and deliver to the Forward Purchaser shares of the Company’s common stock in exchange for cash proceeds per share, before any underwriting discount and offering expenses, equal to the forward sale price, which will initially be $67.40, and will be subject to certain adjustments as provided in the Forward Sale Agreements. The Company may, in certain circumstances, elect cash settlement for all or a portion of its obligations under the Forward Sale Agreements.

The Company intends to use any net proceeds that it receives upon settlement of the Forward Sale Agreements described above or upon any issuance and sale to the Underwriter of shares of the Company’s common stock in the offering to fund development and redevelopment activities, fund potential acquisition opportunities, repay maturing debts, and/or for general corporate purposes.

The Offering is described in the prospectus supplement of the Company, dated January 15, 2015, together with the related prospectus, filed with the Securities and Exchange Commission (the “Commission”) on March 4, 2014.
