The following communication was made available by VEREIT, Inc. to its tenants on April 29, 2021.

Dear [Tenant/Vendor Name],

I am writing to share exciting news with you. VEREIT has entered into a definitive agreement to merge with Realty Income, which will create a $50 billion real estate enterprise with the ability to capture tremendous future growth opportunities. The strategic combination of two highly complementary companies results in increased size, scale, and diversification. The combined portfolio will amount to approximately 10,300 primarily single-tenant, net lease commercial real estate properties located in 50 U.S. states, Puerto Rico and the United Kingdom.

By joining forces with Realty Income, we are creating an even stronger company that is poised to benefit from increased scale. This will enable us to offer our tenants even greater options when it comes to advancing their real estate objectives. Importantly, this merger reflects our conviction in our platform and advances our strategy to acquire high-quality, single-tenant net lease retail and industrial assets leased to clients that are leaders in their respective businesses.

We expect the transaction to close during the fourth quarter of 2021, subject to certain closing conditions. Until then, it remains business as usual with Realty Income and VEREIT continuing to operate as separate and distinct companies. We expect a smooth integration process with no interruption to our day-to-day operations.

It’s important to note that today’s news in no way affects our commercial relationship. All invoicing protocols and payment terms remain the same.

Know that we remain committed to our partnership with your firm and value our relationship. If you have any questions, please reach out to your VEREIT point of contact. All of us at VEREIT are very excited about this transaction and the opportunities it will create for all our stakeholders over the long-term.

Sincerely,

Paul McDowell

Chief Operating Officer

Forward-Looking Statements

This communication may include “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act. All statements other than statements of historical fact are “forward-looking statements” for purposes of federal and state securities laws. These forward-looking statements, which are based on current expectations, estimates and projections about the industry and markets in which Realty Income and VEREIT operate and beliefs of and assumptions made by Realty Income management and VEREIT management, involve uncertainties that could significantly affect the financial or operating results of Realty Income, VEREIT, the combined company or any company spun-off by the combined company. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “will,” and variations of such words and similar expressions are intended to identify such forward-looking statements. Such forward-looking statements include, but are not limited to, statements about the benefits of the proposed transactions involving Realty Income and VEREIT, including future financial and operating results, plans, objectives, expectations and intentions. All statements that address operating performance, events or developments that we expect or anticipate will occur in the future — including statements relating to creating value for stockholders, benefits of the proposed transactions to clients, employees, stockholders and other constituents of the combined company, integrating our companies, cost savings and the expected timetable for completing the proposed transactions — are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained and, therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. For example, these forward-looking statements could be affected by factors including, without limitation, risks associated with the ability to consummate the proposed merger and the timing of the closing of the proposed merger; the ability to secure favorable interest rates on any borrowings incurred in connection with the proposed transactions; the impact of indebtedness incurred in connection with the proposed transactions; the ability to successfully integrate our operations and employees; the ability to realize anticipated benefits and synergies of the proposed transactions as rapidly or to the extent anticipated by financial analysts or investors; potential liability for a failure to meet regulatory or tax-related requirements, including the maintenance of REIT status; material changes in the dividend rates on securities or the ability to pay dividends on common shares or other securities; potential changes to tax legislation; changes in demand for developed properties; adverse changes in the financial condition of joint venture partner(s) or major tenants; risks associated with the acquisition, development, expansion, leasing and management of properties; risks associated with the ability to consummate the proposed spin-off of a company holding the office property assets of Realty Income and VEREIT (“SpinCo”) and the terms thereof, and the timing of the closing of the proposed spin-off; risks associated with the ability to consummate any sales of office property assets of Realty Income and VEREIT and the impact of such sales on SpinCo or the combined company; failure to obtain debt financing to capitalize SpinCo; risks associated with the geographic concentration of Realty Income, VEREIT or SpinCo; risks associated with the industry concentration of tenants; the potential impact of announcement of the proposed transactions or consummation of the proposed transactions on business relationships, including with clients, employees, customers and competitors; unfavorable outcomes of any legal proceedings that have been or may be instituted against Realty Income, VEREIT or any company spun-off by the combined company; costs related to uninsured losses, condemnation, or environmental issues; the ability to retain key personnel; costs, fees, expenses and charges related to the proposed transactions and the actual terms of the financings that may be obtained in connection with the proposed transactions; changes in local, national and international financial markets, insurance rates and interest rates; general adverse economic and local real estate conditions; the inability of major tenants to continue paying their rent obligations due to bankruptcy, insolvency or a general downturn in their business; foreign currency exchange rates; increases in operating costs and real estate taxes; changes in dividend policy or ability to pay dividends for Realty Income’s or VEREIT’s common stock or preferred stock; impairment charges; unanticipated changes in Realty Income’s or VEREIT’s intention or ability to prepay certain debt prior to maturity and/or hold certain securities until maturity; pandemics or other health crises, such as coronavirus (COVID-19); and those additional risks and factors discussed in reports filed with the U.S. Securities and Exchange Commission (“SEC”) by Realty Income and VEREIT. Moreover, other risks and uncertainties of which Realty Income or VEREIT are not currently aware may also affect each of the companies’ forward-looking statements and may cause actual results and the timing of events to differ materially from those anticipated. The forward-looking statements

made in this communication are made only as of the date hereof or as of the dates indicated in the forward-looking statements, even if they are subsequently made available by Realty Income or VEREIT on their respective websites or otherwise.
