Item 8.01 Other Events.

On September 29, 2014, Sabra Health Care REIT, Inc. (the “Company”) entered into an underwriting agreement (the “Underwriting Agreement”) with Merrill Lynch, Pierce, Fenner & Smith Incorporated and Barclays Capital Inc., as representatives of the several underwriters named therein (the “Underwriters”), pursuant to which the Company agreed to issue and sell 6,000,000 shares of the Company’s common stock, $0.01 par value per share (the “Common Stock”), at a price to the public of $24.25 per share. The Company granted the Underwriters a 30-day option to purchase up to an additional 900,000 shares of its Common Stock. The Company expects to issue and deliver the shares of Common Stock on or about October 3, 2014, subject to customary closing conditions.

The Company estimates that the net proceeds of the offering, after deducting underwriting discounts and estimated offering expenses, will be approximately $138.9 million, and approximately $159.9 million if the Underwriters exercise their option to purchase additional shares of Common Stock in full. The Company intends to contribute the net proceeds from the offering to its subsidiary, Sabra Health Care Limited Partnership, which will in turn apply the net proceeds to repay borrowings outstanding on the Company’s revolving credit facility.

The offering was made pursuant to an automatic shelf registration statement filed with the Securities and Exchange Commission on May 20, 2013 (File No. 333-188696), a base prospectus, dated May 20, 2013, included as part of the registration statement, and a prospectus supplement, dated September 29, 2014, filed with the Securities and Exchange Commission on September 30, 2014 pursuant to Rule 424(b) under the Securities Act of 1933, as amended. The Company is filing as Exhibit 5.1 to this Current Report on Form 8-K an opinion of Venable LLP regarding certain matters of Maryland law, including the validity of the shares of Common Stock to be issued and sold in the offering, and as Exhibit 8.1 an opinion of Fried, Frank, Harris, Shriver & Jacobson LLP regarding certain tax matters.

The foregoing description of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the complete text of the Underwriting Agreement, which is filed as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 8.01.
