Item 8.01 Other Events

On June 29, 2026, Realty Income Corporation (the

“Company,” “Realty Income,” “our,” “us” or “we,” which terms include, unless

otherwise expressly stated or the context otherwise requires, its consolidated subsidiaries) provided certain updates with respect to

its capital raising, liquidity matters and certain financing matters, as set forth below.

Unless as otherwise indicated or the context otherwise

requires, for purposes of the following disclosures, (a) references to our “$4.0 billion revolving credit facility,” our “revolving

credit facilities,” and similar references mean our $4.0 billion unsecured revolving credit facility (excluding an additional $1.0

billion expansion option, which is subject to obtaining lender commitments and other customary conditions), references to our “$1.38

billion fund credit facility, our “fund credit facility” and similar references mean Realty Income U.S. Core Plus Aggregator

II, LP’s $1.0 billion unsecured revolving credit facility and $380.0 million unsecured delayed draw term loan facility (excluding

a $620.0 million expansion option, which is subject to obtaining lender commitments and other customary conditions), and references

to our “commercial paper programs” and similar references mean, collectively, our U.S. Dollar-denominated and Euro-denominated

unsecured commercial paper programs; (b) references to our “clients” mean our tenants; (c) references to “GBP”

is to the lawful currency of the United Kingdom and references to “Euro” and “€” are to the lawful currency

of the European Union. For purposes of determining the aggregate amount of borrowings outstanding under our revolving credit facilities

as of any specified date, borrowings denominated in GBP and Euros are translated into U.S. dollars using the applicable currency exchange

rates as in effect from time to time and (d) references to “Pro-Rata Share” mean our proportionate

economic ownership of our joint ventures, which is derived by applying our economic ownership percentage of each such joint venture to

calculate our proportionate share of the relevant line item information being presented, and aggregating that information for all such

joint ventures.

Notes Issuance

On April 7, 2026, we issued $800.0 million

of our 4.750% senior unsecured notes due April 2033 (the “2033 notes”). The public offering price for the 2033 notes

was 98.261% of the principal amount for an effective semi-annual yield to maturity of 5.047%. In connection with the offering, we executed

a $500 million U.S. Dollar-to-Euro 7-year cross currency swap, resulting in approximately €436 million of proceeds and a blended

coupon rate of 4.16%.

ATM Program Refresh

On May 7, 2026, we replaced our prior at-the-market

(“ATM”) program with a new ATM program, pursuant to which we may offer and sell up to 150.0 million shares of common stock

(1) by us to, or through, a consortium of banks acting as our sales agents or (2) by a consortium of banks acting as forward sellers on

behalf of the relevant forward purchasers contemplated thereunder, in each case by means of ordinary brokers’ transactions on the

NYSE under the ticker symbol “O” at prevailing market prices or at negotiated prices.

Liquidity

As of June 25, 2026, we had approximately $4.0 billion

total available liquidity at our Pro-Rata Share, comprised of the components summarized below (dollars in millions):

Cash and cash equivalents(1)

$ 242.4

Availability under credit facilities(2)

3,472.1

Unsettled ATM forwards

2,056.8

Less: commercial paper borrowings

(1,759.8 )

Total available liquidity at our Pro-Rata Share

$ 4,011.5

(1) Reflects adjustments for our share based on our proportionate economic ownership of our joint ventures.

Calculated as cash and cash equivalents per the consolidated balance sheet of $256.8 million, plus our Pro-Rata Share of unconsolidated

entities cash of $9.9 million, less adjustments allocable to noncontrolling interests of $24.3 million.

(2) Represents our availability under the $4.0 billion revolving credit facility and our Pro-Rata Share of

availability under the $1.38 billion fund credit facility.

Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking

statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended,

or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. When used herein, the

words “estimate,” “anticipate,” “assume,” “expect,” “believe,” “intend,”

“continue,” “should,” “may,” “likely,” “plan,” “seek,” and similar

expressions are intended to identify forward-looking statements. Forward-looking statements include discussions of our business, strategy,

plans, and the intentions of management; our platform; growth and capital strategies including our private capital business, investment

pipeline and intentions to acquire or dispose of properties (including geographies, timing, partners, clients and terms); operations and

results; and settlement of shares of common stock sold pursuant to forward sale confirmations under our ATM program.

Forward-looking statements are subject to risks,

uncertainties, and assumptions about us which may cause our actual future results to differ materially from expected results. Some of

the factors that could cause actual results to differ materially are, among others, our continued qualification as a real estate investment

trust; general domestic and foreign business, economic, or financial conditions; competition; fluctuating interest and currency rates;

inflation and its impact on our clients and us; access to debt and equity capital markets and other sources of funding (including the

terms, structure and partners of such funding); volatility and uncertainty in the credit and financial markets; other risks inherent in

real estate, private capital, credit and mezzanine investments, and joint ventures or co-investment ventures, including solvency, defaults

under leases, bankruptcies, potential liability relating to environmental matters, illiquidity of real estate investments (including rights

of first refusal or rights of first offer), and potential damages from natural disasters; impairments in the value of our real estate

assets; volatility and changes in domestic and foreign laws and the application, enforcement or interpretation thereof (including with

respect to tax laws and rates); property ownership through co-investment ventures, funds, joint ventures, partnerships and other arrangements

which, among other things, may transfer or limit our control of the underlying investments; epidemics or pandemics; the loss of key personnel;

the threat and outcome of any legal proceedings to which we are a party or which may occur in the future; acts of terrorism and war; and

the anticipated benefits from mergers, acquisitions, co-investment ventures, funds, joint ventures, partnerships and other arrangements;

and those additional risks and factors discussed in our reports filed with the U.S. Securities and Exchange Commission. Readers are cautioned

not to place undue reliance on forward-looking statements. Those forward-looking statements are not guarantees of future plans and performance

and speak only as of the date of this report. Past operating results and performance are provided for informational purposes and are not

a guarantee of future results. There can be no assurance that historical trends will continue. Actual plans and results may differ materially

from what is expressed or forecasted in this report and forecasts made in the forward-looking statements discussed in this report may

not materialize. We do not undertake any obligation to update forward-looking statements or to publicly release the results of any forward-looking

statements that may be made to reflect events or circumstances after the date these statements were made or to reflect the occurrence

of unanticipated events.
