Will my vote make a difference?

Yes. Your vote is needed to ensure that the proposals can be acted upon. Because we are a widely held company,Company,YOUR VOTE IS VERY IMPORTANT! Your immediate response will help avoid potential delays and may save us significant additional expenses associated with soliciting stockholder votes.

What is a quorum?

A quorum is the presence, either in person or by proxy, of stockholders entitled to cast a majority of all the votes entitled to be cast at the meeting. There must be a quorum for the meeting to be held. In accordance with Maryland law, abstentions, withholds and broker non-votes are counted for the purposes of determining the presence or absence of a quorum for the transaction of business. For purposes of determining the approval of any matter submitted to the stockholders for a vote, however, the election inspectors will treat abstentions and broker non-votes as unvoted.

Similarly, the affirmative vote of a majority of the votes cast by shares present in person or represented by proxy at the Annual Meeting is required to ratify the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for 2018.2020.

Unless otherwise required by our Charter or Maryland law, other matters properly submitted for approval by the stockholders must receive the affirmative vote of a majority of the votes cast at the Annual Meeting.

How is my vote counted?

If you properly execute a proxy card in the accompanying form and we receive it prior to voting at the Annual Meeting, the shares that the proxy represents will be voted in the manner specified on the proxy card. If no specification is made, the shares will be voted FOR the nominees for Director in Proposal One, FOR the ratification of the appointment of our independent registered public accounting firm in Proposal Two and as recommended by ourthe Board of Directors with regard to all other matters in its discretion.

How will voting on stockholder proposals be conducted?

We do not know of other matters that are likely to be brought before the Annual Meeting. However, if any other matters properly come before the Annual Meeting, your signed proxy card gives authority to the persons named therein to vote your shares on those matters in accordance with their discretion.

Who will pay the cost for this proxy solicitation and how much will it cost?

CPA:18 – Global will pay the cost of preparing, assembling and mailing this Proxy Statement, the Notice of Meeting and the enclosed proxy card. In addition to the solicitation of proxies by mail, we may utilize some of the officers and employees of our advisor and affiliate, Carey Asset Management Corp., and/or its affiliates (who will receive no compensation in addition to their regular salaries), to solicit proxies personally and by telephone. We intend to retain a solicitation firm, Broadridge Investor Communications Solutions, Inc., to assist in the solicitation of proxies for a fee estimated to be up to $40,000,$25,000, plus out-of-pocket expenses. We may ask banks, brokers, and other custodians, nominees and fiduciaries to forward copies of the Proxy Statement to their principals and request authority for the execution of proxies, and will reimburse such persons for their expenses in so doing.

The Board of Directors did not retain any such advisor or consultant during 2017.2019.

The Audit Committee's policy is to pre-approve all audit and permissible non-audit services provided by the Independent Registered Public Accounting Firm. These services may include audit services, audit-related services, tax services and other services. Pre-approval is generally provided for up to one year and is detailed as to the particular service or category of services. The Independent Registered Public Accounting Firm and management are required to periodically report to the Audit Committee regarding the extent of services provided by the Independent Registered Public Accounting Firm in accordance with such

pre-approval and the fees for the services performed to date. The Audit Committee may also pre-approve particular services on a case-by-case basis.

If a non-audit service is required before the Audit Committee's next scheduled meeting, the Committee has delegated to its Chairman, Mr. Pinola, the authority to approve such services on its behalf, provided that such action is reported to the Committee at its next meeting.

Our advisor is charged with assessing and managing risks associated with our business on a day-to-day basis. We rely on our advisor's internal processes to identify, manage and mitigate material risks and to communicate with our Board of Directors. The Board of Directors' role is to oversee the advisor's execution of these responsibilities and to assess the advisor's approach to risk management on our behalf. The Board of Directors exercises this role periodically as part of its regular meetings and through meetings of its Audit Committee. The Board of Directors and the Audit Committee receive reports at their regular meetings from representatives of our advisor on areas of material risk to CPA:18 – Global, including operational, financial, legal, regulatory, strategic and reputational risk, in order to review and understand risk identification, risk management and risk mitigation strategies.

We maintain separate roles for our Chairman of the Board and Chief Executive Officer in recognition of the differences between the two roles. Our Non-Executive Chairman of the Board, Ms. Munson, one of our Independent Directors, presides over meetings of the full Board of Directors and, when necessary, acts as the primary liaison between our Independent Directors and our advisor. Our Independent Directors meet regularly in executive session and maintain an open line of communication with our Chief Executive Officer. Our Board appointed Ms. Munson as Non-Executive Chairman of the Board of Directors in May 2013. Our Board believes that Ms. Munson is well-suited for her role as Chairman based on her extensive board and executive level experience.

Our Chief Executive Officer, who is also the Chief Executive Officer of WPC, has the general responsibility for implementing our policies and for the management of our business and affairs. Mr. Mark J. DeCesaris served as our Chief Executive Officer and President, as well as a member of our Board of Directors, from February 10, 2016 to December 31, 2017, when he retired from his positions as our Chief Executive Officer and President, as well as a member of our Board of Directors, in connection with his retirement as the Chief Executive Officer of WPC effective as of that date. On January 1, 2018, Mr. Fox succeeded Mr. DeCesaris as our Chief Executive Officer and President, and joined our Board of Directors.

There were five regular Board of Directors meetings, two additional Board of Director meetings and eight Audit Committee meetings held in 2017, and each Director attended at least seventy-five percent of the aggregate Audit Committee meetings and Board meetings held during the year while he or she was a Director. The Board of Directors of CPA:18 – Global does not have standing nominating or compensation committees. Although there is no specific policy regarding Director attendance at meetings of stockholders, Directors are invited and encouraged to attend. All of our Directors attended the 2017 annual meeting of stockholders held on June 14, 2017.

We have no employees. Day-to-day management functions are performed by our advisor. During 2017, we did not pay any compensation to our Executive Officers. We have not paid, and do not intend to pay, any annual compensation to our Executive Officers for their service as officers. In addition, we do not reimburse our advisor for compensation or benefits paid to our Executive Officers, however, we reimburse our advisor for the services of personnel other than our Executive Officers. Please see the section titled "Certain Relationships and Related Transactions" for a description of the contractual arrangements between us and our advisor and its affiliates.

CPA:18 – Global pays to each of its Directors who are not officers an annual cash retainer of $50,000 and an annual grant of $25,000 of shares of common stock (valued based upon the most recently published estimated net asset value per share ("NAV") of our Class A shares). In addition, the Chairman of our Audit Committee in 2017, Mr. Pinola, received an annual cash retainer of $10,000 during the year. Mr. DeCesaris, who was a member of CPA:18 – Global's Board of Directors until December 31, 2017, did not receive compensation for serving as a Director.

Amounts in the "Stock Awards" column reflect the grant date fair value of awards of shares of our Class A common stock granted for 2017, computed in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation, related to the annual grant of shares of our Class A common stock on July 3, 2017. The grant date fair values of awards were calculated by multiplying the number of shares granted by $7.90, the NAV of our Class A shares at the time of the grant date.

(2)

All Other Compensation reflects dividends paid during 2017 on the stock awards set forth in the table.

SEC regulations require the disclosure of the compensation policies applicable to Executive Officers in the form of a report by the compensation committee of the Board of Directors (or a report of the full Board of Directors in the absence of a compensation committee). As noted above, CPA:18 – Global has no employees, paid no direct compensation and made no executive compensation decisions during 2017. As a result, CPA:18 – Global has no compensation committee, and the Board of Directors has not considered a compensation policy for employees and has not included a report with this Proxy Statement. Pursuant to the advisory agreement, CPA:18 – Global reimbursed our advisor for CPA:18 – Global's proportional share of the cost incurred during 2017 by the advisor and other affiliates of WPC in paying for expenses related to

personnel other than our Executive Officers. Please see the section titled "Certain Relationships and Related Transactions" for details regarding reimbursements to WPC and its affiliates of personnel expenses pursuant to the advisory agreement.

As noted above, CPA:18 – Global's Board of Directors has not appointed a compensation committee. None of the members of CPA:18 – Global's Board of Directors are involved in a relationship requiring disclosure as an interlocking Executive Officer/Director, under Item 404 of Regulation S-K, or as a former officer or employee of CPA:18 – Global.

CPA:18 – Global's Board of Directors has adopted a Code of Ethics that sets forth the standards of business conduct and ethics applicable to all of our officers, including our Executive Officers and Directors. This code is available on the Company's website (www.cpa18global.com) in the "Corporate Governance" section. We also intend to post amendments to or waivers from the Code of Ethics at this location on the website.

Until December 31, 2017, Mr. DeCesaris served as a member of our Board of Directors and as our Chief Executive Officer and President; he also served as the Chief Executive Officer and a Director of WPC, the parent company of our advisor. Effective as of December 31, 2017, Mr. DeCesaris retired from his positions as a member of our Board of Directors and as our Chief Executive Officer and President in connection with his retirement as Chief Executive Officer of WPC effective as of that date. On January 1, 2018, Mr. Fox succeeded Mr. DeCesaris as our Chief Executive Officer and President, as well as a member of our Board of Directors, and as Chief Executive Officer and a member of the Board of Directors of WPC.

During 2017, we retained our advisor to provide advisory services in connection with identifying, evaluating, negotiating, financing, purchasing and disposing of investments, to perform day-to-day management services and certain administrative duties for us pursuant to the advisory agreement. The advisor earns asset management and other fees, and an affiliate of the advisor holds a membership interest in our operating partnership subsidiary entitling the affiliate to certain cash distributions. Asset management fees are payable in cash or shares of our Class A common stock at our option, after consultation with the advisor. For 2017, we paid our advisor its asset management fees in shares of our Class A common stock.

During 2017, we paid the advisor approximately $11.2 million in asset management fees. Our operating partnership paid approximately $8.7 million in distributions of available cash to an affiliate of our advisor pursuant to the operating partnership agreement.

In addition, in return for performing services related to CPA:18 – Global's investment acquisitions, the advisor is paid acquisition fees, a portion of which is payable upon acquisition of investments for making of such investments or for the development or construction of properties with the remainder subordinated to a preferred return threshold. During 2017, in connection with the acquisition of investments, we capitalized current and deferred acquisition fees of approximately $3.8 million and $3.0 million, respectively.

During 2017, we made payments of deferred acquisition fees (including interest) to our advisor totaling $11.6 million. At December 31, 2017, unpaid installments of current and deferred acquisition fees (including interest) totaled approximately $6.7 million. Pursuant to the advisory agreement with our advisor, the cumulative total acquisition costs that we incur, including acquisition fees paid to the advisor, may not exceed 6.0% of the aggregate contract purchase price of all investments, which is measured at the end of each year. As of the year ended December 31, 2017, cumulative total acquisition costs did not exceed 6.0%.

The advisor may also receive subordinated disposition fees for services provided in connection with CPA:18 – Global's liquidation subject to certain conditions. We did not incur any subordinated disposition fees during 2017.

Pursuant to the dealer manager agreement between us and Carey Financial, LLC ("Carey Financial"), an affiliate of WPC, Carey Financial received an on-going annual distribution and shareholder servicing fee in connection with our Class C shares. The amount of the distribution and shareholder servicing fee is 1.0% of the NAV of our Class C shares. The distribution and shareholder servicing fee accrues daily and is payable quarterly in arrears. We will no longer incur the distribution and shareholder servicing fee beginning on the date at which, in the aggregate, underwriting compensation from all sources, including the distribution and shareholder servicing fee, any organizational and offering fee paid for underwriting and underwriting compensation paid by WPC and its affiliates, equals 10.0% of the gross proceeds from our initial public offering, which we have not yet reached.

Effective as of June 30, 2017, WPC exited all non-traded retail fundraising activities carried out by Carey Financial. As a result, beginning with the fees for the third quarter of 2017, we now pay the annual distribution and shareholder servicing fees for our Class C common stock directly to the selected dealers, rather than through Carey Financial. There is no change in the amount of distribution and shareholder servicing fees that we incur. During 2017, we made payments for the distribution and shareholder servicing fee totaling approximately $2.2 million.

We own interests in property-owning entities ranging from 50% to 97%, with the remaining interests held by CPA:17 – Global or third parties.

Because we do not have our own employees, the advisor employs, directly and through its affiliates, officers and other personnel to provide services to us, including our Executive Officers. During 2017, we incurred approximately $3.8 million payable to the advisor or its affiliates to cover (i) personnel expenses, which includes both cash compensation and employee benefits, but excludes amounts paid by the advisor to the Executive Officers (which are not reimbursable by us) and (ii) certain other overhead expenses, such as office rental expenses, which we pay a proportionate share of based on our gross revenues. In addition, during 2017, we capitalized personnel and overhead reimbursements of approximately $0.6 million.

In July 2016, WPC agreed to make available to us a short-term line of credit of up to $50.0 million in loans, in the aggregate, at a rate equal to the rate at which WPC is able to borrow funds under its existing credit facility, for acquisition funding purposes. Any such loans are made solely at the discretion of WPC's management. At December 31, 2017, we had no such loans outstanding from WPC.

All of the transactions that we enter into with related persons, such as our Directors, Officers, and their immediate family members, must be, after disclosure of such affiliation, approved or ratified by a majority of our Directors (including a majority of Independent Directors) who are not otherwise interested in the transaction. In addition, such Directors and Independent Directors must determine that (i) the transaction is in all respects on such terms as, at the time of the transaction and under the circumstances then prevailing, fair and reasonable to our stockholders, and (ii) the terms of such transaction are at least as favorable as the terms then prevailing for comparable transactions made on an arm's-length basis. In addition, our Charter provides that we may purchase or lease assets from WPC, our advisor, our Directors or affiliates of any of the foregoing if a majority of our Directors (including a majority of Independent Directors) not otherwise interested in the transaction determines that: (a) such transaction is fair and reasonable to us and at a price equal to the cost of the asset to WPC, our advisor, our Directors or their affiliates, or (b) if the price to us is in excess of such cost, that there is a substantial justification for such excess and such excess is reasonable.

Section 16(a) of the Exchange Act requires that our Directors, Executive Officers and any persons who are the beneficial owners of more than 10% of our shares file reports of their ownership and changes in ownership of our shares with the SEC and to furnish us with copies of all such Section 16 reports that they file. Based upon a review of the copies of such reports furnished to us as filed with the SEC and other written representations that no other reports were required to be filed during the year, we believe

that our Directors and Executive Officers were in compliance with the reporting requirements of Section 16(a) during 2017, except that Mr. Fox filed his initial statement of beneficial ownership on Form 3, reporting that he did not beneficially own any securities of the Company on the date he became our Chief Executive Officer and a Director, two weeks late due to an administrative error by the Company. We know of no stockholder who beneficially owned more than 10% of our stock.

The Board of Directors will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by committee charters and subject to any required assistance or advice from legal counsel, Ms. Susan C. Hyde, Chief Administrative Officer and Secretary, is primarily responsible for monitoring communications from stockholders and for providing copies or summaries of such communications to the Directors as she considers appropriate. This monitoring process has been approved by our Independent Directors.

We must receive at our principal executive offices any proposal that a stockholder intends to present at CPA:18 – Global's 2019 Annual Meeting no later than December 27, 2018 in order to be included in CPA:18 – Global's Proxy Statement and form of proxy relating to the 2019 Annual Meeting pursuant to SEC Rule 14a-8 under the Exchange Act.

In addition, nominations by stockholders of candidates for Director or proposals of other business by stockholders, whether or not intended to be included in our proxy materials, must be submitted in accordance with our Bylaws in order to be considered at our 2019 Annual Meeting. Our Bylaws currently provide that, in order to bring any business or nominations before an annual meeting of stockholders, the stockholder must give timely notice of such nomination or proposal in writing to

To be timely, a stockholder's notice must contain all the information set forth in Section 11 of Article II of our Bylaws and be delivered to the Secretary of CPA:18 – Global at the principal executive offices of CPA:18 – Global not earlier than 150 days nor later than 5:00 p.m., New York City Time, on the 120th day prior to the first anniversary of the mailing of the notice for the preceding year's annual meeting (unless the date of the annual meeting is advanced or delayed by more than 30 days from the first anniversary of the preceding year's annual meeting, in which case the notice must be delivered to our Secretary not earlier than 150 days prior to the date of the annual meeting and not later than 5:00 p.m., New York City Time, on the later of the 120th day prior to the date of the annual meeting or the tenth day following the day on which public announcement of the date of the meeting is first made). Accordingly, under our current Bylaws, a stockholder nomination or proposal intended to be considered at the 2019 Annual Meeting must be received by us no earlier than November 27, 2018 and not later than December 27, 2018. Our Secretary will provide a copy of our Bylaws upon written request and without charge.
