ESCONDIDO, CALIFORNIA, January 22, 2013….Realty Income Corporation (Realty Income), The Monthly Dividend Company^®, (NYSE:O), today announced it has formally closed the acquisition of American Realty Capital Trust (ARCT) that was approved by both Realty Income and ARCT shareholders at their shareholder meetings held on January 16, 2013.

All of the required merger documents to complete the acquisition of ARCT have been filed, and the combined company will trade under the ticker symbol “O” on the New York Stock Exchange at the opening of the market on January 23, 2013. In accordance with the January 6, 2013 Amendment to the September 6, 2012 Merger Agreement, ARCT shareholders will receive a one-time cash payment of $0.35 per share in addition to the fixed exchange ratio of 0.2874 Realty Income shares for each share of ARCT common stock that they own.

Former ARCT shareholders will receive Realty Income shares allocated according to the number of ARCT shares held on the January 22, 2013 closing date, and a one-time cash payment will be distributed either by the investment firm where shares are held, or by Wells Fargo Shareowner Services, Realty Income’s transfer agent. The timing for completion of the transfer of shares will vary depending on whether shares are held at an investment firm or with the former ARCT transfer agent. Some ARCT shareholders may be required to fill out transfer forms in order to complete the transfer to Realty Income shares.
