NEW YORK ( TheStreet) -- After some initial push back by some American Realty Capital Trust ( ARCT) shareholders, it appears the proposed merger announced back in September 2012 with Realty Income ( O) is now preparing to close.Last week, both companies announced that ARCT shareholders have approved the $3 billion deal with Realty Income issuing 45.6 million shares of common stock, based on a fixed exchange ratio of 0.2874 shares of Realty Income stock for each share of ARCT common stock owned. ARCT shareholders will receive a one-time cash payment of $0.35 per share. The transaction will be essentially balance sheet neutral. In an effort to seal the deal, Realty Income agreed to boost the company's common stock dividend to $0.1809167 per share from $0.15175 per share. When the dividend is increased, it will be the 70th dividend increase since Realty Income was listed on the NYSE in 1994. The new monthly dividend amount will represent an annualized dividend of $2.171 per share, as compared to the previous annualized dividend of $1.821 per share, or an increase of 19.2%. Upon closing (later in January), the triple-net deal will create the world's largest net-leased REIT and the 18th-largest publicly traded REIT. The combined company will have an $8.4 billion market capitalization and an enterprise value of $12.4 billion, a size that makes it a candidate for inclusion in the S&P 500. Realty Income will add 515 freestanding commercial properties that are owned by ARCT to the company's real estate portfolio. These properties are freestanding locations, which are net-leased to primarily investment-grade-rated tenants doing business in 27 industries. Some of ARCT's largest tenants include FedEx ( FDX), Walgreen ( WAG), CVS ( CVS), the Government Services Administration, Dollar General ( DG), Express Scripts ( ESRX) and PNC Bank ( PNC). After adding these properties, Realty Income will own a total of 3,528 properties leased to 202 tenants doing business in 48 industries. Approximately 34% of the anticipated lease revenue will be generated by investment grade rated tenants, as compared to 19% prior to the ARCT acquisition. In addition, Realty Income will achieve increased diversification by industry, tenant and property type, increasing the number of industries to 48 from 44, the number of tenants to 202 from 150, and diversifying the property types to 77% retail, 11% distribution facility, 6% office, 3% agriculture, 2% manufacturing and 1% industrial.
