Item 1. Security and Issuer

This Schedule 13D relates to the common stock, $0.01 par value per share (the “Shares”), of American Realty Capital Properties, Inc., a Maryland corporation (the “Issuer”). The address of the Issuer’s principal executive offices is 405 Park Ave., 15th Floor, New York, NY 10022.

Item 2. Identity and Background

This statement on Schedule 13D is filed by Corvex Management LP, a Delaware limited partnership (“Corvex”) and Keith Meister, a U.S. citizen. This statement relates to Shares held for the account of certain private investment funds for which Corvex acts as investment adviser, including Corvex Master Fund, LP, a Cayman Islands limited partnership, the general partner of which is controlled by Mr. Meister (collectively, the “Corvex Funds”). The general partner of Corvex is also controlled by Mr. Meister. The principal business address of each of Corvex and Mr. Meister is 712 Fifth Avenue, 23rd Floor, New York, New York 10019. The principal business of Corvex is serving as the investment adviser of the Corvex Funds, whose principal business is investing in securities. Mr. Meister’s principal occupation is serving as the Managing Partner of Corvex.

Each of Corvex and Mr. Meister is referred to as a “Reporting Person” and collectively as the “Reporting Persons.” Each of the Reporting Persons is party to that certain Joint Filing Agreement, as further described in Item 6 and attached as Exhibit 1 hereto.

During the last five years, none of Corvex, Mr. Meister or any of the Corvex Funds has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or has been party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

Item 3. Source and Amount of Funds or Other Consideration

The responses to Items 4, 5 and 6 and the information set forth in Exhibit 2 of this Schedule 13D are incorporated herein by reference.

The Reporting Persons used working capital of the Corvex Funds to purchase the 7,925,000 Shares reported herein (the “Owned Shares”) and to acquire the original call options referenced in Item 5 and Exhibit 2. The total purchase price for the Owned Shares was $71,063,853 including brokerage commissions and the purchase price to acquire such call options was $158,072,416 including brokerage commissions.

The Reporting Persons may effect purchases of securities through margin accounts maintained for them with brokers, which extend margin credit as and when required to open or carry positions in their margin accounts, subject to applicable federal margin regulations, stock exchange rules and such firms’ credit policies. Positions in Shares may be held in margin accounts and may be pledged as collateral security for the repayment of debit balances in such accounts. Such margin accounts may from time to time have debit balances. In addition, since other securities may be held in such margin accounts, it may not be possible to determine the amounts, if any, of margin used to purchase Shares.

Item 4. Purpose of Transaction

The responses to Items 3, 5 and 6 of this Schedule 13D are incorporated herein by reference.

The Reporting Persons acquired the Shares and options referred to in Item 5 over which they exercise beneficial ownership in the belief that the Shares of the Issuer are undervalued and an attractive investment. The Reporting Persons have had and expect to continue to have discussions with the Issuer’s Board of Directors, management and advisors with respect to the Issuer’s business and strategies.

We commend the Board’s decision to retain qualified advisors in seeking to promptly resolve past issues and position the company to look to the future rather than focusing on the past. It is clear to the Reporting Persons that this is a time of transition and a unique opportunity for a ‘new start’ for the company and its shareholders.

        The Reporting Persons believe that it is beneficial to add representatives of the shareholders to the Board, particularly given the recent high level of personnel turnover at the company and the critical decisions the company is facing in the near term. Consequently, the Reporting Persons have had discussions with the Board to explore the addition to the Board of a representative of the Reporting Persons and potentially other independent persons which might be suggested by the Reporting Persons. Further, the Reporting Persons have had and will continue to have discussions with the Board to share thoughts for enhancing value for all shareholders. Such discussions include, but are not limited to: business strategy and simplification, stabilizing and enhancing the value of Cole Capital, capital allocation, the search process for a new CEO and Chairman, and corporate governance. The Reporting Persons may enter into discussions with other shareholders, industry participants and third parties in connection with all or some of the matters referenced in this Item 4.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may from time to time and at any time in the future depending on various factors, including, without limitation, the outcome of any discussions referenced above, the Issuer’s financial position and strategic direction, actions taken by the Board, price levels of the Shares, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, take such actions with respect to their investments in the Issuer as they deem appropriate, including, without limitation: (i) acquiring additional Shares and/or other equity, debt, notes, other securities, or derivative or other instruments that are based upon or relate to the value of the Shares or the Issuer (collectively, “Securities”) of the Issuer in the open market or otherwise; (ii) disposing of any or all of their Securities in the open market or otherwise; (iii) engaging in any hedging or similar transactions with respect to the Securities; or (iv) proposing or considering one or more of the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.

Item 5. Interest in Securities of the Issuer

The percentages used in this Item and in the rest of the Schedule 13D are calculated based upon an aggregate of 907,984,706 Shares outstanding on September 2, 2014, as reported in the Issuer’s Annual Report on Form 10-K Amendment filed on September 4, 2014.
