Item 1.01 Entry into a Material Definitive Agreement.

Merger Agreement

On August 8, 2016, Global Net Lease, Inc. (the “Company”) and its operating partnership, Global Net Lease Operating Partnership, L.P. (the “Company OP”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with American Realty Capital Global Trust II, Inc., (the “Target”), American Realty Capital Global II Operating Partnership, L.P. (the “Target OP”) and Mayflower Acquisition LLC, a Maryland limited liability company and wholly owned subsidiary of the Company (“Merger Sub”).  The Merger Agreement provides for (i) the merger of the Target with and into Merger Sub (the “REIT Merger”), with Merger Sub surviving as a wholly owned subsidiary of the Company and (ii) the merger of the Target OP with and into the Company OP (the “Partnership Merger”, and together with the REIT Merger, the “Mergers”). A special committee of the board of directors of the Company (the “Board”) recommended, and the Board unanimously approved, the Merger Agreement, the Mergers and the other transactions contemplated by the Merger Agreement.

Pursuant to the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Mergers (the “Effective Time”), each outstanding share of common stock, including restricted shares of common stock, of the Target, $0.01 par value per share (“Target Common Stock”) other than shares owned by the Company, any subsidiary of the Company or any wholly owned subsidiary of the Target, will be converted into the right to receive 2.27 shares of common stock of the Company, par value $0.01 per share (“Company Common Stock”) (such consideration, the “Merger Consideration”), and at the effective time of the Partnership Merger (the “Partnership Merger Effective Time”), each outstanding unit of limited partnership interest and Class B interest of the Target OP issued and outstanding immediately prior to the Partnership Merger Effective Time will be converted into the right to receive 2.27 shares of Company Common Stock (the “Partnership Merger Consideration”).

The Merger Agreement further provides that immediately prior to the Effective Time, any outstanding restricted stock of the Target will become fully vested and will have the right to receive the Merger Consideration.

The completion of the Mergers is subject to various conditions, including, among other things, the approval of the Merger and the other transactions contemplated by the Merger Agreement by the affirmative vote of a majority of the votes of the Company’s common stockholders cast at a meeting of the Company’s common stockholders, a quorum being present, and the approval of the Merger and the other transactions contemplated by the Merger Agreement by the Target’s common stockholders holding a majority of the outstanding shares of Target Common Stock. Moreover, each party’s obligation to consummate the Mergers is subject to certain other conditions, including the accuracy of the other party’s representations and warranties (subject to customary qualifications) and the other party’s material compliance with its covenants and agreements contained in the Merger Agreement, including, among other things, the Company’s obligation to prepare and file a registration statement on Form S-4 to register the offer and sale of shares of Company Common Stock to be issued pursuant to the Merger Agreement.

The Company and the Target have made certain customary representations and warranties and covenants for transactions of this type, including with respect to the conduct of business by each of the Company and the Target prior to the closing. Notably, under the terms of the Merger Agreement, the Target and the Target OP and their representatives may initiate, solicit, provide information and enter into discussions concerning proposals relating to alternative business combination transactions until September 22, 2016 (the “Go Shop Period”), and thereafter, until the receipt of the approval of the Merger and the Merger Agreement by the Target stockholders, the Target and the Target OP and their representatives may continue to participate in such discussions with any third party who submitted a bona fide proposal prior to the end of the Go Shop Period that has not been withdrawn and where the special committee of the Target’s board of directors has determined in good faith that such proposal has resulted in, or would be reasonably expected to lead to, a Superior Proposal (as defined in the Merger Agreement). Following the Go Shop Period, certain covenants prohibit the Target and the Target OP and their representatives from initiating, soliciting, providing information or entering into discussions concerning proposals relating to alternative business combination transactions, subject to certain limited exceptions.

The Merger Agreement provides that, in connection with the termination of the Merger Agreement under specified circumstances, including following a breach by the non-terminating party or a change in recommendation of the non-terminating party, one party may be required to pay to the other a termination fee of $6,000,000 plus reasonable out-of-pocket transaction expenses (up to a maximum of $5,000,000 in expenses). However, if the Merger Agreement is terminated in connection with the Target entering into or recommending a qualified Superior Proposal with a bidder on or before the date that is 15 days following the end of the Go Shop Period, the termination fee payable by the Target to the Company would be $1.2 million plus the Company’s reasonable out-of-pocket expenses (up to a maximum of $5,000,000 in expenses).

The Company and the Target each are sponsored, directly or indirectly, by AR Global Investments, LLC (“AR Global”). AR Global and its affiliates provide investment and advisory services to the Company and the Target pursuant to written advisory agreements. In connection with, and subject to the terms and conditions of, the Merger Agreement, certain equity interests in the Target OP held by AR Global and its affiliates that are subject to forfeiture will, consistent with the terms of the Target OP partnership agreement, no longer be subject to forfeiture and will be exchanged for Company Common Stock in the Partnership Merger.

A copy of the Merger Agreement is attached hereto as Exhibit 2.1 and is incorporated herein by reference. The foregoing summary description of the material terms of the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Merger Agreement. The representations and warranties in the Merger Agreement were made as of a specified date, may be subject to a contractual standard of materiality different from what might be viewed as material to stockholders, or may have been used for the purpose of allocating risk between the parties. Accordingly, the representations and warranties in the Merger Agreement are not necessarily characterizations of the actual state of facts about the Company or the Target at the time they were made or otherwise and should only be read in conjunction with the other information that the Company makes publicly available in reports, statements and other documents filed with the Securities and Exchange Commission (the “SEC”).

Item 7.01 Regulation FD Disclosure.

The Company prepared an investor presentation with respect to the contemplated Mergers. Directors, officers and other representatives of the Company and the Target will present some or all of such investor presentation to various conferences and meetings in the coming months.

Such investor presentation shall not be deemed “filed” for any purpose, including for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. The information in this Item 7.01, including Exhibit 99.2, shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act regardless of any general incorporation language in such filing.
