Item 8.01. Other Events.

On July 26, 2016, Cedar Realty Trust, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) by and among the Company, Cedar Realty Trust Partnership, L.P., Merrill Lynch, Pierce, Fenner & Smith Incorporated, as underwriter and forward seller (the “Underwriter”), and Bank of America, N.A., as forward purchaser (the “Forward Purchaser”), relating to the forward issuance and sale to the Underwriter of 5,000,000 shares of the Company’s common stock (“Common Stock”), par value $0.06 per share (the “Offering”). On July 27, 2016, the Underwriter exercised in full its option to purchase an additional 750,000 shares of Common Stock pursuant to the Underwriting Agreement. The Offering closed on August 1, 2016.

The shares were offered and sold under a prospectus supplement and related prospectus filed with the Securities and Exchange Commission pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-203667).

In connection with the Offering, the Company entered into forward sale agreements, dated July 26, 2016 and July 27, 2016 (the “Forward Sale Agreements”), between the Company and the Forward Purchaser, pursuant to which an affiliate of the Forward Purchaser borrowed from third parties and sold to the Underwriter an aggregate of 5,750,000 shares of Common Stock. Pursuant to the terms of the Forward Sale Agreements, and subject to its right to elect cash or net share settlement, the Company expects to issue 5,750,000 shares of Common Stock to the Forward Purchaser upon physical settlement of the Forward Sale Agreements at the then-applicable forward sale price. The Forward Sales Agreements provide for a forward price of $7.71 per share, subject to certain adjustments. Settlement is expected to occur on one or more dates no later than August 1, 2017, subject to acceleration by the Forward Purchaser upon the occurrence of certain events.

The Company presently intends to use all the net proceeds received upon the settlement of the Forward Sale Agreements for general working capital and other corporate purposes, including the repayment of outstanding indebtedness and the acquisition of additional properties.

The foregoing descriptions of the Underwriting Agreement and Forward Sale Agreements are qualified in their respective entirety by the terms and conditions of the Underwriting Agreement and Forward Sale Agreements, which are filed as Exhibits 1.1, 1.2 and 1.3 hereto, respectively, and incorporated herein by reference.
