American Realty Capital Properties, Inc. Stockholder Letter Fourth Quarter 2012 and Subsequent Events

American Realty Capital Properties, Inc. Stockholder Letter Dear Stockholder: n 2012 and the fi rst quarter of 2013, American Realty Capital Properties (NASDAQ: ARCP) made signifi cant progress in meeting all of its primary goals: completed a transformative merger with ARCT III; outperformed its peer group; announced its sixth consecutive quarterly dividend; executed on its acquisition program at prices accretive to its dividend; continued to build out its equity base, completing two equity offerings and fi ling a universal shelf; increased its credit facility. This has enabled ARCP to solidify its unique and highly competitive position within the net lease sector. The Company had an outstanding 2012 and Q1 2013, and we could not be more enthusiastic about the year ahead. We will continue to maintain a high quality real estate investment vehicle and provide our investors durable dividends, principal protection and the opportunity for outsized asset appreciation. Our focus will remain on aggregating properties accretive to our dividend, growing our earnings, and increasing our dividend. Let’s review 2012 highlights, Q4 2012 achievements and what is in store for 2013. 2012 and Q1 2013 in Review • Returned nearly 38% in 2012, surpassing our triple net peers and the broader markets by a signifi cant margin (See Exhibit A) • By the fi rst quarter of 2013, had announced 6 consecutive quarterly dividend increases since our IPO • Purchased 58 properties, totaling 1.4 million square feet, for a total purchase price of $131.8 million at an average cap rate of 9.7% in 2012. YTD 2013, acquired approximately $40 million and placed an additional $167 million under contract • Completed two follow-on equity offerings totaling approximately $60 million through early January 2013 • Achieved fl exible capital options through the fi ling of a $500 million universal shelf registration and entered into an “at-the-market” program • Automatic shelf registration fi led and acheivement of “well-known seasoned issuer” status (WKSI) • Completed a transformative merger in February 2013, totaling approximately $3.1 billion enterprise value, with ARCT III • Increased existing credit facility to $1.65 billion, subject to customary conditions with the option to exercise our “accordion” feature to $2.5 billion Completion of ARCT III Merger In December 2012, ARCP and ARCT III executed a merger agreement under which ARCP agreed to acquire all of the outstanding shares of ARCT III. This transformative transaction was approved by both companies’ boards of directors and stockholders and the merger closed on February 28, 2013. ARCP has now become one of the largest publicly-traded net lease REITs and one of the largest publicly-traded REITs in the U.S. This successful combination enhances our real estate portfolio quality, further diversifi es our asset base, and creates a net lease portfolio with high credit quality tenants of long-term and mid-term lease durations. The signifi cantly increased enterprise value of $3.1 billion offers the potential to lower the cost of our equity and debt capital, positions us for future MSCI and Russell Index inclusions, and moves us closer to achieving an investment grade credit rating. ARCP expects to realize $48 million in operating cost savings over a fi ve-year period. Common Stock Performance ARCP returned almost 8% for the fourth quarter on a total return basis – outperforming the MSCI, its triple net peers and the broader equity markets by wide margins of 444 to 556 bps. For the 12 month period ended December 31, 2012, ARCP returned nearly 38% on a total return basis, again outperforming its peers, the REIT index and the broader equity markets by more than 13% to 21%. ARCP gained another 140 basis points of total return through the close of its merger on February 28, 2013.

American Realty Capital Properties, Inc. Stockholder Letter Acquisitions and Future Pipeline During the 12 months ended December 31, 2012, ARCP acquired 58 properties comprising approximately 1.4 million square feet, all 100% occupied, for an aggregate base purchase price of $131.8 million at an average capitalization rate of 9.7%. Q4’ 2012 acquisitions alone included three Family Dollar stores, one FedEx facility, one Fresenius dialysis center, 14 Advance Auto stores, two Walgreens stores and one Synovus Bank branch, which totaled $32.9 million, exclusive of closing costs, and increased the portfolio’s size, at cost, to $268.6 million. These 22 properties totaled over 200,000 square feet located in 10 states, and were acquired at an average capitalization rate of 9.0%. Acquisitions that have recently closed in March 2013 include a FedEx Ground distribution facility leased to a subsidiary of FedEx Corporation (NYSE: FDX), and a TD Bank offi ce building in Falmouth, Maine. The FedEx distribution facility encompasses 68,425 rentable square feet, is located in Lowell, Arkansas, and was purchased for $8.8 million at an average capitalization rate of 9.0%. The TD Bank offi ce building contains 143,030 rentable square feet and was purchased for $31.0 million at an average capitalization rate of 8.9%. With an attractive second quarter 2013 pipeline already assembled, we see no shortage of net lease acquisition opportunities with favorable pricing and will continue to add quality, credit tenants at yields accretive to ARCP’s dividend. To achieve our current FFO and AFFO guidance, we intend to acquire approximately $1.1 billion of assets in 2013, which is inclusive of approximately $200 million of assets already closed through February 28, 2013. An additional $167.0 million of acquisitions have been placed under contract and are expected to close within 60 days of the writing of this letter. Signifi cant Balance Sheet Initiatives We took several important steps in both Q4 2012 and the beginning of 2013 to position our balance sheet appropriately and increase our earnings. • Completed Follow-On Offering: On January 24, 2013, ARCP priced an underwritten public follow-on offering of 1,800,000 shares of common stock. The offering price to the public in the offering was $13.47 per share (before underwriting discounts and commissions). The offering closed on January 29, 2013, for a total share count of 2,070,000, after the underwriters fully exercised their option to purchase an additional 270,000 shares of common stock at the public offering price. As a result, ARCP received total net proceeds of approximately $26.5 million, after deducting underwriting discounts, commissions and estimated expenses. • Launched “ATM” Program: In January 2013, ARCP launched its “at-themarket” equity offering (“ATM”) program in which it may from time to time offer and sell shares of its common stock having aggregate offering proceeds of up to $60.0 million. The ATM program allows us to issue small amounts of equity to match-fund our acquisitions with low issuance costs. The shares will be issued pursuant to ARCP’s $500.0 million universal shelf registration statement. As of February 28, 2013, ARCP issued 61,000 shares at a weighted average price per share of $13.48 for net proceeds of $0.8 million pursuant to the ATM program. A total of $59.2 million of shares of common stock remained available for issuance under the ATM program. • Increased Commitment on Facility: In March 2013, ARCP received additional commitments totaling $650.0 million to its existing credit facility which signifi cantly increases our fi nancial fl exibility. The additional commitments increase the total amount available to the Company to $1.65 billion, subject to customary conditions. The accordion feature of this credit facility has been increased to allow ARCP, with additional commitments, to borrow up to $2.5 billion. • Achieved Automatic Shelf Registration: ARCP fi led a $500.0 million universal automatic shelf registration and achieved “well known seasoned issuer” status (WKSI). The shelf registration increases our fi nancial fl exibility and access to capital market. • Locked in Favorable Financing: ARCP’s initial draw down of $515 million from its existing line was achieved at an extremely favorable fi xed rate of 2.45%. Value Creation ARCP continues to deliver value to its stockholders. The recent merger with ARCT III increased market recognition and bolstered already strong stock performance. We intend to build off of this positive momentum. As mentioned previously, we will continue to maintain a high quality real estate investment vehicle, providing our investors durable dividends, principal protection and the opportunity for signifi cant growth. A keen focus will be placed on buying accretive to cost, increasing our dividend and focusing on earnings growth. Let me close by saying thank you to all of our stockholders, old and new. It has been an exciting journey thus far, and we certainly appreciate your ongoing support. We believe we have a superior net lease REIT, complete with a best in class portfolio of high quality, primarily investment grade properties, a solid balance sheet and an experienced management team. As in all our investment programs, management’s interests remain closely aligned with those of our stockholders, and we stand fi rmly committed to putting our stockholders fi rst. Sincerely, Nicholas S. Schorsch Chairman & Chief Executive Officer
