under the Securities Act of 1933, as amended.

A copy of the press release is attached as Exhibit 99.1

to this Current Report on Form 8-K and is incorporated by reference into this Item 8.01.

Neither this Current Report on Form 8-K nor

common stock, if any, issuable upon conversion of the Notes.

Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains, or may contain, 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 in this Current Report on Form 8-K, 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 statements

regarding the Notes, including the conversion thereof, the intended use of the net proceeds including the repurchase of shares of the

Company’s common stock, and the timing and consummation of the offering of the Notes and the capped call transactions relating to the Notes.

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 contained in this Current Report on Form 8-K. These forward-looking statements are not guarantees of future plans and

performance. Actual plans and results may differ materially from what is expressed or forecasted in this Current Report on Form 8-K

and forecasts made in the forward-looking statements discussed in this Current Report on Form 8-K might not materialize. We do not

undertake any obligation to update forward-looking statements or other information contained in this Current Report on Form 8-K or

to publicly release the results of any revisions to these forward-looking statements that may be made to reflect events or circumstances

after the respective dates or filing dates, as the case may be, of those documents or to reflect the occurrence of unanticipated events.

Exhibit 99.1

Realty Income Prices Upsized $875.0

Million Convertible Senior Notes Offering

SAN DIEGO, CALIFORNIA, August 11,

2026....Realty Income Corporation (Realty Income, NYSE: O), The Monthly Dividend Company®, today announced the

pricing of its offering of $875.0 million aggregate principal amount of 3.750% convertible

senior notes due 2031 (the “notes”) in a private offering (the “offering”) to persons reasonably believed to

be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities

Act”). The offering size was increased from the previously announced offering size of $750.0 million aggregate principal

amount of notes. The issuance and sale of the notes are scheduled to settle on August 14, 2026, subject to customary closing

conditions. Realty Income also granted the initial purchasers of the notes an option to purchase, for settlement within a period of

13 days from, and including, the date the notes are first issued, up to an additional $125.0 million aggregate principal amount of

notes.

The

notes will be senior, unsecured obligations of Realty Income and will accrue interest at a rate of 3.750% per annum, payable

semi-annually in arrears on February 15 and August 15 of each year, beginning on February 15, 2027. The

notes will mature on August 15, 2031, unless earlier repurchased, redeemed or converted.

Before

May 15, 2031, noteholders will have the right to convert their notes only upon the occurrence of certain events. From and after May 15,

2031, noteholders may convert their notes at any time at their election until the close of business on the second scheduled trading day

immediately before the maturity date. The initial conversion rate is 13.7512 shares of common stock per $1,000 principal

amount of notes, which represents an initial conversion price of approximately $72.72 per share of common stock.

The initial conversion price represents a premium of approximately 17.5% over the last reported sale price of

$61.89 per share of Realty Income's common stock on August 11, 2026. The conversion rate and conversion

price will be subject to adjustment upon the occurrence of certain events. Realty Income will settle conversions by paying cash up to

the aggregate principal amount of the notes to be converted and paying or delivering, as the case may be, cash, shares of Realty Income’s

common stock or a combination of cash and shares of Realty Income’s common stock, at Realty Income’s election, in respect

of the remainder, if any, of Realty Income’s conversion obligation in excess of the aggregate principal amount of the notes being

converted, based on the then applicable conversion rate.

Except in the event

of a cleanup redemption or a REIT preservation redemption (each as defined below), Realty Income may not

redeem the notes prior to August 20, 2029. Realty Income will have the right to redeem

the notes, in whole or in part (subject to certain limitations), for cash at Realty Income’s option at any time, and from time

to time, on or after August 20, 2029 and on or before the 20th scheduled trading day immediately

before the maturity date, but only if the last reported sale price per share of Realty Income's common stock exceeds 130% of the conversion

price for a specified period of time and certain other conditions are satisfied.

Realty Income may redeem for cash all, but not

less than all, of the notes at any time if the aggregate principal amount of the notes that remains outstanding as of the redemption

notice date is less than 10% of the aggregate principal amount of the notes initially issued under the indenture (including any notes

issued pursuant to the initial purchasers’ option to purchase additional notes) and certain other conditions are satisfied (a “cleanup

redemption”).

Realty Income will also have the right to redeem

the notes, in whole or in part, at Realty Income’s option at any time prior to maturity to the extent, and only to the extent,

necessary to preserve its status as a real estate investment trust (“REIT”) for U.S. federal income tax purposes (a “REIT

preservation redemption”).

In each case, the redemption price for any note

called for redemption will be a cash amount equal to the principal amount of the notes to be redeemed, plus accrued and unpaid interest

to, but excluding, the redemption date.

If a “fundamental change” (as defined

in the indenture for the notes) occurs, which includes certain business combination transactions involving Realty Income and certain

de-listing events with respect to Realty Income’s common stock, then, subject to a limited exception, noteholders may require Realty

Income to repurchase their notes for cash. The repurchase price will be equal to the principal amount of the notes to be repurchased,

plus accrued and unpaid interest, if any, to, but excluding, the applicable repurchase date.

Use of Proceeds and Concurrent Share Repurchases

Realty

Income estimates that the net proceeds from the offering will be approximately $859.0 million (or

approximately $981.9 million if the initial purchasers fully exercise their option to purchase additional notes), after

deducting the initial purchasers’ discounts and commissions and Realty Income’s estimated offering expenses. Realty

Income intends to use approximately $29.1 million of the net proceeds from this offering to pay the cost of the capped

call transactions described below. Realty Income expects to use approximately $188.7 million of the net proceeds from this

offering to repurchase approximately 3.0 million shares of Realty Income’s common stock concurrently with the pricing of this

offering in privately negotiated transactions effected through one of the initial purchasers of the notes or its affiliate, as

Realty Income’s agent. These repurchases could increase (or reduce the size of any decrease in) the market price of Realty

Income’s common stock or the notes, and repurchases executed concurrently with the pricing of the offering may have affected

the initial terms of the notes, including the initial conversion price. Realty Income intends to use the remainder of the net

proceeds from this offering for general corporate purposes, which may include, among other

things, the repayment or repurchase of certain indebtedness (including borrowings under Realty Income’s revolving credit

facilities and commercial paper programs), foreign currency swaps or other hedging instruments, the development, redevelopment and

acquisition of additional properties, acquisition or business combination transactions, and the expansion and improvement of certain

properties in Realty Income’s portfolio.

Capped Call Transactions

connection with the pricing of the notes, Realty Income entered into privately negotiated capped call transactions with one or more

of the initial purchasers or their affiliates and/or one or more other financial institutions (the “option

counterparties”). The capped call transactions are expected generally to reduce the potential dilution to Realty

Income’s common stock upon any conversion of the notes and/or offset any potential cash payments Realty Income is required to

make in excess of the principal amount of the converted notes, as the case may be, with such reduction and/or offset subject to a

cap. If, however, the market price per share of Realty Income’s common stock, as measured under the terms of the capped call

transactions, exceeds the cap price of the capped call transactions, there would nevertheless be dilution and/or there would not be

an offset of such potential cash payments, in each case, to the extent that such market price exceeds the cap price of the capped

call transactions. The capped call transactions will cover, subject to anti-dilution adjustments substantially similar to those

applicable to the notes, the number of shares of Realty Income’s common stock that will initially underlie the notes. The cap

price of the capped call transactions will initially be approximately $83.55 per share of Realty Income’s common stock, which

represents a premium of approximately 35.0% above the closing price of Realty Income’s common stock of $61.89 per

share on the New York Stock Exchange on August 11, 2026, and is subject to certain adjustments under the terms of the capped

call transactions. If the initial purchasers of the notes exercise their option to purchase additional notes, Realty Income expects

to use a portion of the additional net proceeds to fund the cost of entering into additional capped call transactions with the

option counterparties.

Realty Income expects that, in connection with

establishing their initial hedges of the capped call transactions, the option counterparties or their respective affiliates expect to

enter into various derivative transactions with respect to Realty Income’s common stock and/or purchase shares of Realty Income’s

common stock concurrently with or shortly after the pricing of the notes. This activity could increase (or reduce the size of any decrease

in) the market price of Realty Income’s common stock or the notes at that time. In addition, Realty Income expects that the option

counterparties or their respective affiliates may modify their hedge positions by entering into or unwinding various derivatives with

respect to Realty Income’s common stock and/or by purchasing or selling shares of Realty Income’s common stock or other securities

of Realty Income in secondary market transactions following the pricing of the notes and prior to the maturity of the notes (and are

likely to do so (x) during any observation period related to a conversion of notes or following any repurchase of notes by Realty Income

in connection with any redemption or fundamental change, (y) following any repurchase of the notes by Realty Income other than in connection

with any redemption or fundamental change if Realty Income elects to unwind a corresponding portion of the capped call transactions in

connection with such repurchase and (z) if Realty Income otherwise unwinds all or a portion of the capped call transactions). This activity

could also cause or avoid an increase or a decrease in the market price of Realty Income’s common stock or the notes, which could

affect the ability of holders of the notes to convert the notes and, to the extent the activity occurs during any observation period

related to a conversion of the notes, it could affect the number of shares of Realty Income’s common stock, if any, and value of

the consideration that holders of the notes will receive upon conversion of the notes.

Important Information

The offer and sale of the notes and any shares

of Realty Income’s common stock issuable upon conversion of the notes have not been, and will not be, registered under the Securities

Act or any other securities laws, and the notes and any such shares cannot be offered or sold except pursuant to an exemption from, or

in a transaction not subject to, the registration requirements of the Securities Act and any other applicable securities laws. This press

release does not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any offer or sale of, the notes

(or any shares of Realty Income’s common stock issuable upon conversion of the notes) in any state or jurisdiction in which the

offer, solicitation or sale would be unlawful prior to the registration or qualification thereof under the securities laws of any such

state or jurisdiction.
