Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation Realty Income Corporation (“Realty Income,” the “Company,” “we,” “our” or “us”) was founded in 1969 and is organized as a Maryland corporation. We invest in commercial real estate and have elected to be taxed as a real estate investment trust ("REIT"). We are listed on the New York Stock Exchange ("NYSE") under the symbol “O”. As of September 30, 2023, we owned or held interests in a diversified portfolio of 13,282 properties located in all 50 states of the United States ("U.S."), Puerto Rico, the United Kingdom ("U.K."), Spain, Italy, and Ireland, with approximately 262.6 million square feet of leasable space. Our accompanying unaudited consolidated financial statements were prepared from our books and records in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). In the opinion of management, all adjustments (consisting of only normal recurring accruals) necessary to present a fair statement of results for the interim periods presented have been included. Operating results for the three and nine months ended September 30, 2023 are not necessarily an indication of the results that may be expected for the entire year. Readers of this quarterly report should refer to our audited consolidated financial statements for the year ended December 31, 2022, which are included in our 2022 Annual Report on Form 10-K , as certain disclosures that would substantially duplicate those contained in the audited financial statements have not been included in this report. The U.S. dollar (“USD”) is our reporting currency. Unless otherwise indicated, all dollar amounts are expressed in USD. For our consolidated subsidiaries whose functional currency is not the USD, we translate their financial statements into USD at the time we consolidate those subsidiaries’ financial statements. Generally, assets and liabilities are translated at the exchange rate in effect at the balance sheet date. The resulting translation adjustments are included in 'Accumulated other comprehensive income' ("AOCI") in the consolidated balance sheets. Certain balance sheet items, primarily equity and capital-related accounts, are reflected at the historical exchange rate. Income statement accounts are translated using the average exchange rate for the period. We and certain of our consolidated subsidiaries have intercompany and third-party debt that is not denominated in our functional currency. When the debt is remeasured to the functional currency of the entity, a gain or loss can result. The resulting adjustment is reflected in ' Foreign currency and derivative (loss) gain, net ' in the consolidated statements of income and comprehensive income. Intercompany accounts and transactions are eliminated in consolidation. Principles of Consolidation. These consolidated financial statements include the accounts of Realty Income and all other entities in which we have a controlling financial interest. We evaluate whether we have a controlling financial interest in an entity in accordance with Accounting Standards Codification ("ASC") 810, Consolidation. Voting interest entities are entities considered to have sufficient equity at risk and which the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities in which we have a controlling financial interest, which we typically have through holding of a majority of the entity’s voting equity interests. Variable interest entities ("VIEs") are entities that lack sufficient equity at risk or where the equity holders either do not have the obligation to absorb losses, do not have the right to receive residual returns, do not have the right to make decisions about the entity’s activities, or some combination of the above. A controlling financial interest in a VIE is present when an entity has a variable interest, or a combination of variable interests, that provides the entity with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. An entity that meets both conditions above is deemed the primary beneficiary and consolidates the VIE. We reassess our initial evaluation of whether an entity is a VIE when certain reconsideration events occur. We reassess our determination of whether we are the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances. At September 30, 2023, Realty Income, L.P. and certain investments, including investments in joint ventures, are considered VIEs in which we were deemed the primary beneficiary based on our controlling financial interests. Below is a summary of selected financial data of consolidated VIEs included in the consolidated balance sheets at September 30, 2023, and December 31, 2022 (in thousands): September 30, 2023 December 31, 2022 Net real estate $ 2,494,915 $ 920,032 Total assets $ 3,161,113 $ 1,082,346 Total liabilities $ 119,552 $ 60,127 The portion of a consolidated entity not owned by us is recorded as a noncontrolling interest. Noncontrolling interests are reflected on our consolidated balance sheets as a component of equity. Noncontrolling interests that were created or assumed as part of a business combination or asset acquisition were recognized at fair value as of the date of the transaction (see note 9, Noncontrolling Interests ). Reclassification . Certain prior period amounts have been reclassified to conform to the current year presentation. Value-added tax receivable is included in 'Other assets, net', in the consolidated balance sheets. Previously, this was categorized as 'Accounts receivable, net' in the consolidated balance sheets. Use of Estimates . The consolidated financial statements were prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Segment Reporting. We report our results in a single reportable segment, which reflects how our chief operating decision maker allocates resources and assesses our performance. Income Taxes. We have elected to be taxed as a REIT, under the Internal Revenue Code of 1986, as amended. We believe we have qualified and continue to qualify as a REIT. Under the REIT operating structure, we are permitted to deduct dividends paid to our stockholders in determining our taxable income. Assuming our dividends equal or exceed our taxable net income in the U.S., we generally will not be required to pay U.S. income taxes on such income. Accordingly, no provision has been made for federal income taxes in the accompanying consolidated financial statements, except for federal income taxes of our taxable REIT subsidiaries ("TRS"). A TRS is a subsidiary of a REIT that is subject to federal, state and local income taxes, as applicable. Our use of TRS entities enables us to engage in certain business activities while complying with the REIT qualification requirements and to retain any income generated by these businesses for reinvestment without the requirement to distribute those earnings. For our international territories, we are liable for taxes in the United Kingdom and Spain. Accordingly, provisions have been made for U.K. and Spain income taxes. Therefore, the income taxes recorded on our consolidated statements of income and comprehensive income represent amounts accrued or paid by Realty Income and its subsidiaries for U.S. income taxes on our TRS entities, city and state income and franchise taxes, and income taxes for the U.K. and Spain. Earnings and profits that determine the taxability of distributions to stockholders differ from net income reported for financial reporting purposes primarily due to differences in the estimated useful lives and methods used to compute depreciation and the carrying value (basis) of the investments in properties for tax purposes, among other things. We regularly analyze our various international, federal and state filing positions and only recognize the income tax effect in our financial statements when certain criteria regarding uncertain income tax positions have been met. We believe that our income tax positions would more likely than not be sustained upon examination by all relevant taxing authorities. Therefore, no provisions for uncertain tax positions have been recorded on our consolidated financial statements. Lease Revenue Recognition and Accounts Receivable. The majority of our leases are accounted for as operating leases. Under this method, leases that have fixed and determinable rent increases are recognized on a straight-line basis over the lease term. Any rental revenue contingent upon our client’s sales, or percentage rent, is recognized only after our client exceeds their sales breakpoint. Rental increases based upon changes in the consumer price indexes are recognized only after the changes in the indexes have occurred and are then applied according to the lease agreements. Contractually obligated rental revenue from our clients for recoverable real estate taxes and operating expenses are included in contractually obligated reimbursements by our clients, a component of rental revenue, in the period when such costs are incurred. Taxes and operating expenses paid directly by our clients are recorded on a net basis. Other revenue includes certain property-related revenue not included in rental revenue and interest income recognized on financing receivables for certain leases with above-market terms. We assess the probability of collecting substantially all of the lease payments to which we are entitled under the original lease contract as required under Topic 842, Leases . We assess the collectability of our future lease payments based on an analysis of creditworthiness, economic trends and other facts and circumstances related to the applicable clients. If we conclude the collection of substantially all lease payments under a lease is less than probable, rental revenue recognized for that lease is limited to cash received going forward, existing operating lease receivables, including those related to straight-line rental revenue, must be written off as an adjustment to rental revenue, and no further operating lease receivables are recorded for that lease until such future determination is made that substantially all lease payments under that lease are now considered probable. If we subsequently conclude that the collection of substantially all lease payments under a lease is probable, a reversal of lease receivables previously written off is recognized. Concentration of Credit Risk. There were no clients who accounted for more than more than 10% of our total revenue for each of the nine months ended September 30, 2023, and 2022.

Real Estate [Abstract]
Investments in Real Estate	Investments in Real Estate A. Acquisitions of Real Estate Below is a summary of our acquisitions for the nine months ended September 30, 2023: Number of Leasable Investment Weighted Initial Weighted Average Cash Lease Yield (1) Acquisitions - U.S. 802 14,730 $ 3,708.9 15.9 6.9 % Acquisitions - Europe 80 8,608 2,191.6 15.6 7.1 % Total acquisitions 882 23,338 $ 5,900.5 15.8 7.0 % Properties under development (2) 305 7,269 910.0 16.2 6.7 % Total (3) 1,187 30,607 $ 6,810.5 15.8 6.9 % (1) The initial weighted average cash lease yield for a property is generally computed as estimated contractual first year cash net operating income, which, in the case of a net leased property, is equal to the aggregate cash base rent for the first full year of each lease, divided by the total cost of the property. Since it is possible that a client could default on the payment of contractual rent (defined as the monthly aggregate cash amount charged to clients, inclusive of monthly base rent receivables), we cannot provide assurance that the actual return on the funds invested will remain at the percentages listed above. Contractual net operating income used in the calculation of initial weighted average cash lease yield includes approximately $3.7 million received as settlement credits as reimbursement of free rent periods for the nine months ended September 30, 2023. In the case of a property under development or expansion, the contractual lease rate is generally fixed such that rent varies based on the actual total investment in order to provide a fixed rate of return. When the lease does not provide for a fixed rate of return on a property under development or expansion, the initial weighted average cash lease yield is computed as follows: estimated cash net operating income (determined by the lease) for the first full year of each lease, divided by our projected total investment in the property, including land, construction and capitalized interest costs. (2) Includes £32.6 million of investments in four U.K. development properties and €25.9 million of investment in two Spain development properties, converted at the applicable exchange rates on the funding dates. (3) Our clients occupying the new properties are 89.7% retail, 10.0% industrial, and 0.3% other property types based on annualized contractual rent. Approximately 25% of the annualized contractual rent generated from acquisitions during the nine months ended September 30, 2023 is from investment grade rated clients, their subsidiaries, or affiliated companies. The aggregate purchase price of the assets acquired during the nine months ended September 30, 2023 has been allocated as follows (in millions): Acquisitions - USD Acquisitions - Sterling Acquisitions - Euro Land (1) $ 727.7 £ 434.7 € 17.3 Buildings and improvements 2,640.0 824.8 24.2 Lease intangible assets (2) 371.9 122.2 15.6 Other assets (3) 560.3 326.1 1.6 Lease intangible liabilities (4) (110.2) (11.0) (0.8) Other liabilities (5) (8.7) (1.8) — $ 4,181.0 £ 1,695.0 € 57.9 (1) Sterling-denominated land includes £3.2 million of right of use assets under long-term ground leases. (2) The weighted average amortization period for acquired lease intangible assets is 9.7 years. (3) USD-denominated other assets consist entirely of financing receivables with above-market terms. Sterling-denominated other assets consist of £135.3 million of financing receivables with above-market terms and £190.8 million of right-of-use assets accounted for as finance leases. (4) The weighted average amortization period for acquired lease intangible liabilities is 11.1 years. (5) USD-denominated other liabilities consist entirely of deferred rent on certain below-market leases. The properties acquired during the nine months ended September 30, 2023 generated total revenues of $174.4 million and net income of $91.6 million during the nine months ended September 30, 2023. B. Investments in Existing Properties During the nine months ended September 30, 2023, we capitalized costs of $43.6 million on existing properties in our portfolio, consisting of $36.5 million for non-recurring building improvements, $6.9 million for re-leasing costs, and $0.2 million for recurring capital expenditures. In comparison, during the nine months ended September 30, 2022, we capitalized costs of $70.6 million on existing properties in our portfolio, consisting of $63.7 million for non-recurring building improvements, $3.9 million for re-leasing costs, and $3.0 million for recurring capital expenditures. C. Properties with Existing Leases The value of the in-place and above-market leases is recorded to 'Lease intangible assets, net' on our consolidated balance sheets, and the value of the below-market leases is recorded to 'Lease intangible liabilities, net' on our consolidated balance sheets. The values of the in-place leases are amortized as depreciation and amortization expense. The amounts amortized to expense for all of our in-place leases, for the nine months ended September 30, 2023, and 2022 were $489.2 million and $476.8 million, respectively. The values of the above-market and below-market leases are amortized over the term of the respective leases, including any bargain renewal options, as an adjustment to rental revenue in the consolidated statements of income and comprehensive income. The amounts amortized as a net decrease to rental revenue for capitalized above-market and below-market leases for the nine months ended September 30, 2023 and 2022 were $48.6 million and $41.2 million, respectively. If a lease was to be terminated prior to its stated expiration, all unamortized amounts relating to that lease would be recorded to revenue or expense, as appropriate. The following table presents the estimated impact during the next five years and thereafter related to the amortization of the above-market and below-market lease intangibles and the amortization of the in-place lease intangibles at September 30, 2023 (dollars in thousands): Net increase (decrease) to rental revenue Increase to amortization expense 2023 $ (15,270) $ 159,999 2024 (55,582) 580,180 2025 (48,736) 499,404 2026 (41,027) 444,691 2027 (32,426) 385,298 Thereafter 353,466 1,753,882 Totals $ 160,425 $ 3,823,454 D.

Our revolving credit facility also has a $1.0 billion expansion option, which is subject to obtaining lender commitments. Under our revolving credit facility, our current investment grade credit ratings provide for USD borrowings at the Secured Overnight Financing Rate ("SOFR"), plus 0.725% with a SOFR adjustment charge of 0.10% and a revolving credit facility fee of 0.125%, for all-in pricing of 0.95% over SOFR, British Pound Sterling at the Sterling Overnight Indexed Average (“SONIA”), plus 0.725% with a SONIA adjustment charge of 0.0326% and a revolving credit facility fee of 0.125%, for all-in pricing of 0.8826% over SONIA, and Euro Borrowings at one-month Euro Interbank Offered Rate (“EURIBOR”), plus 0.725%, and a revolving credit facility fee of 0.125%, for all-in pricing of 0.85% over one-month EURIBOR.

Our Euro-denominated unsecured commercial paper program may be issued in USD or various foreign currencies, including but not limited to, Euros, Sterling, Swiss Francs, Yen, Canadian Dollars, and Australian Dollars, in each case, pursuant to customary terms in the European commercial paper market. The commercial paper ranks on a parity in right of payment with all of our other unsecured senior indebtedness outstanding from time to time, including borrowings under our revolving credit facility, our term loans and our outstanding senior unsecured notes. Proceeds from commercial paper borrowings are used for general corporate purposes. As of September 30, 2023, the balance of borrowings outstanding under our commercial paper programs was $376.8 million, consisting entirely of Euro borrowings, as compared to $701.8 million outstanding commercial paper borrowings, including €361.0 million of Euro-denominated borrowings, at December 31, 2022.

Interest on the remaining senior unsecured notes and bond obligations included in the table is paid semi-annually. (2) In January 2023, in conjunction with the pricing of these senior unsecured notes due January 2026, we entered into three-year, fixed-to-variable interest rate swaps, which are accounted for as fair value hedges. See Note 11, Derivative Instruments for further details. The following table summarizes the maturity of our notes and bonds payable as of September 30, 2023, excluding $64.8 million related to unamortized net premiums, deferred financing costs, and basis adjustment on interest rate swaps designated as fair value hedges (dollars in millions): Year of Maturity Principal 2023 $ — 2024 850.0 2025 1,050.0 2026 2,075.0 2027 1,993.1 Thereafter 11,449.8 Totals $ 17,417.9 As of September 30, 2023, the weighted average interest rate on our notes and bonds payable was 3.7%, and the weighted average remaining years until maturity was 6.6 years.

Our outstanding notes and bonds are unsecured; accordingly, we have not pledged any assets as collateral for these or any other obligations. All of these notes and bonds contain various covenants, including: (i) a limitation on incurrence of any debt which would cause our debt to total adjusted assets ratio to exceed 60%; (ii) a limitation on incurrence of any secured debt which would cause our secured debt to total adjusted assets ratio to exceed 40%; (iii) a limitation on incurrence of any debt which would cause our debt service coverage ratio to be less than 1.5 times; and (iv) the maintenance at all times of total unencumbered assets not less than 150% of our outstanding unsecured debt. At September 30, 2023, we were in compliance with these covenants. B.

Equity [Abstract]
Issuances of Common Stock	Issuances of Common Stock A. At-the-Market ("ATM") Program In August 2023, we replaced our prior ATM program with a new ATM program, pursuant to which we may offer and sell up to 120.0 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 any 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. Upon settlement, subject to certain exceptions, we may elect, in our sole discretion, to cash settle or net share settle all or any portion of our obligations under any forward sale agreement, in which cases we may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and we may owe cash (in the case of cash settlement) or shares of our common stock (in the case of net share settlement) to the relevant forward purchaser. Of the 120.0 million shares of our common stock available for sale under the prior ATM program at its inception, a total of 101.8 million of those shares were sold, the remainder of which were terminated. As of September 30, 2023, we had 102.7 million shares remaining for future issuance under our new ATM program. We anticipate maintaining the availability of our ATM program in the future, including the replenishment of authorized shares issuable thereunder. The following table outlines common stock issuances pursuant to our ATM programs (dollars in millions): Three months ended Nine months ended 2023 2022 2023 2022 Shares of common stock issued under the ATM program (1) 15,070,342 9,532,853 63,209,973 35,506,034 Gross proceeds $ 883.0 $ 696.6 $ 3,880.4 $ 2,424.1 Sales agents' commissions and other offering expenses (9.7) (5.2) (30.4) (20.0) Net proceeds $ 873.3 $ 691.4 $ 3,850.0 $ 2,404.1 (1) During the three and nine months ended September 30, 2023, 23.5 million and 69.7 million shares were sold, respectively, and 15.1 million and 63.2 million shares were settled pursuant to forward sale confirmations, respectively. In addition, as of September 30, 2023, 13.3 million shares of common stock subject to forward sale confirmations have been executed, but not settled, at a weighted average initial gross price of $56.61 per share. We currently expect to fully settle forward sale agreements outstanding by December 31, 2023, representing $749.3 million in net proceeds, for which the weighted average forward price at September 30, 2023 was $56.47 per share. B. Dividend Reinvestment and Stock Purchase Plan ("DRSPP") Our DRSPP, provides our common stockholders, as well as new investors, with a convenient and economical method of purchasing our common stock and reinvesting their distributions. Our DRSPP also allows our current stockholders to buy additional shares of common stock by reinvesting all or a portion of their distributions. Our DRSPP authorizes up to 26.0 million common shares to be issued. At September 30, 2023, we had 11.0 million shares remaining for future issuance under our DRSPP program. The following table outlines common stock issuances pursuant to our DRSPP program (dollars in millions): Three months ended Nine months ended 2023 2022 2023 2022 Shares of common stock issued under the DRSPP program 51,951 43,430 137,732 128,061 Gross proceeds $ 3.0 $ 3.0 $ 8.4 $ 8.7

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). ASC 820, Fair Value Measurements and Disclosures , sets forth a fair value hierarchy that categorizes inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities and lowest priority to unobservable inputs. Categorization within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. • Level 1 – Quoted market prices in active markets for identical assets and liabilities • Level 2 – Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other market-corroborated inputs • Level 3 – Inputs that are unobservable and significant to the overall fair value measurement The following tables present the carrying values and estimated fair values of financial instruments as of September 30, 2023 and December 31, 2022 (in millions): September 30, 2023 Hierarchy Level Carrying Value Level 1 Level 2 Level 3 Assets: Derivative assets $ 44.8 $ — $ 44.8 $ — Total assets $ 44.8 $ — $ 44.8 $ — Liabilities: Mortgages payable $ 822.0 $ — $ — $ 806.1 Notes and bonds payable 17,417.9 — 15,478.2 — Derivative liabilities 78.3 — 78.3 — Total liabilities $ 18,318.2 $ — $ 15,556.5 $ 806.1 December 31, 2022 Hierarchy Level Carrying Value Level 1 Level 2 Level 3 Assets: Derivative assets $ 83.1 $ — $ 83.1 $ — Total assets $ 83.1 $ — $ 83.1 $ — Liabilities: Mortgages payable $ 842.3 $ — $ — $ 810.4 Notes and bonds payable 14,114.2 — 12,522.8 — Derivative liabilities 64.7 — 64.7 — Total liabilities $ 15,021.2 $ — $ 12,587.5 $ 810.4 A. Financial Instruments Not Measured at Fair Value on our Consolidated Balance Sheets The fair value of short-term financial instruments such as cash and cash equivalents, accounts receivable, escrow deposits, loans receivable, accounts payable, distributions payable, line of credit payable and commercial paper borrowings, and other liabilities approximate their carrying value in the accompanying consolidated balance sheets, due to their short-term nature. The aggregate fair value of our term loans approximates carrying value due to the frequent repricing of the variable interest rate charged on the borrowing. The following table reflects the carrying amounts and estimated fair values of our financial instruments not measured at fair value on our consolidated balance sheets (in millions): September 30, 2023 December 31, 2022 Carrying value Fair value Carrying value Fair value Mortgages payable (1) $ 822.0 $ 806.1 $ 842.3 $ 810.4 Notes and bonds payable (2) $ 17,417.9 $ 15,478.2 $ 14,114.2 $ 12,522.8 (1) Excludes non-cash net premiums recorded on the mortgages payable. The unamortized balance of these net premiums was $2.8 million at September 30, 2023, and $12.4 million at December 31, 2022. Also excludes deferred financing costs of $0.6 million at September 30, 2023, and $0.8 million at December 31, 2022. (2) Excludes non-cash net premiums recorded on notes payable. The unamortized balance of the net premiums was $147.5 million at September 30, 2023, and $224.6 million at December 31, 2022. Also excludes deferred financing costs of $78.4 million and basis adjustment on interest rate swaps designated as fair value hedges of $4.4 million at September 30, 2023, and $60.7 million of deferred financing costs at December 31, 2022. The estimated fair values of our mortgages payable and private senior notes payable have been calculated by discounting the future cash flows using an interest rate based upon the relevant forward interest rate curve, plus an applicable credit-adjusted spread. Because this methodology includes unobservable inputs that reflect our own internal assumptions and calculations, the measurement of estimated fair values related to our mortgages payable is categorized as level three on the three-level valuation hierarchy. The estimated fair values of our publicly-traded senior notes and bonds payable are based upon indicative market prices and recent trading activity of our senior notes and bonds payable. Because this methodology includes inputs that are less observable by the public and are not necessarily reflected in active markets, the measurement of the estimated fair values related to our notes and bonds payable is categorized as level two on the three-level valuation hierarchy. B. Financial Instruments Measured at Fair Value on a Recurring Basis For derivative assets and liabilities, we may utilize interest rate swaps, interest rate swaptions, and forward-starting swaps to manage interest rate risk, and cross-currency swaps, currency exchange swaps, and foreign currency forwards to manage foreign currency risk. The valuation of these instruments is determined using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, spot and forward rates, as well as option volatility . Derivative fair values also include credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts, and guarantees. Although we have determined that the majority of the inputs used to value our derivatives fall within level two on the three-level valuation hierarchy, the credit valuation adjustments associated with our derivatives utilize level three inputs, such as estimates of current credit spreads, to evaluate the likelihood of default by ourselves and our counterparties. However, at September 30, 2023, and December 31, 2022, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we determined that our derivative valuations in their entirety are classified as level two. For more details on our derivatives, see note 11, Derivative Instruments. C. Items Measured at Fair Value on a Non-Recurring Basis Impairment of Real Estate Investments Certain financial and nonfinancial assets and liabilities are measured at fair value on a non-recurring basis and are subject to fair value adjustments only under certain circumstances, such as when an impairment write-down occurs. Depending on impairment triggering events during the applicable period, impairments are typically recorded for properties sold, in the process of being sold, vacant, in bankruptcy, or experiencing difficulties with collection of rent. The following table summarizes our provisions for impairment on real estate investments during the periods indicated below (in millions): Three months ended Nine months ended 2023 2022 2023 2022 Carrying value prior to impairment $ 37.5 $ 48.1 $ 161.4 $ 107.0 Less: total provisions for impairment (16.8) (1.7) (59.8) (16.4) Carrying value after impairment $ 20.7 $ 46.4 $ 101.6 $ 90.6 The valuation of impaired assets is determined using valuation techniques including discounted cash flow analysis, analysis of recent comparable sales transactions and purchase offers received from third parties, which are Level 3 inputs. We may consider a single valuation technique or multiple valuation techniques, as appropriate, when estimating the fair value of its real estate. Estimating future cash flows is highly subjective and estimates can differ materially from actual results.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments In the normal course of business, our operations are exposed to economic risks from interest rates and foreign currency exchange rates. We may enter into derivative financial instruments to offset these underlying economic risks. Derivative Designated as Hedging Instruments - Cash Flow Hedges In order to hedge the foreign currency risk associated with interest payments on intercompany loans denominated in British Pound Sterling ("GBP") and Euro ("EUR"), we have a hedging strategy to enter into foreign currency forward contracts to sell GBP, USD, and EUR and buy EUR, USD, and GBP. These foreign currency forwards are designated as cash flow hedges. Forward points on the forward contracts are included in the assessment of hedge effectiveness. Amounts reported in other comprehensive income related to foreign currency derivative contracts will be reclassified to other gain and (loss) in the same period during which the hedged forecasted transactions affect earnings. To add stability to interest expense and to manage our exposure to interest rate movements associated with our term loans, we executed variable-to-fixed interest rate swaps. These interest rate swaps are designated as cash flow hedges. The interest rate swaps are recorded on the consolidated balance sheets at fair value. Changes to fair value are recorded to accumulated other comprehensive income, or AOCI, and subsequently reclassified into interest expense in the same periods during which the hedged transaction affects earnings. To mitigate the impact of fluctuating interest rates, we have also entered into interest rate swaption agreements, structured as a swaption corridor, in anticipation of issuing USD denominated bonds. Interest rate swaption corridors are a combination of two swaption positions, whereby we purchase a payer swaption, which is an option that allows us to enter into a swap where we will pay the fixed rate and receive the floating rate of the swap, and sell a payer swaption, which is an option that provides the counterparty with the right to enter into a swap where we will receive the fixed rate and pay the floating rate of the swap. For the swaption corridor entered into during March 2023, the combination of purchasing the payer swaption and selling the swaption resulted in a premium being paid of $7.6 million. The interest rate swaptions are designated as cash flow hedges. Changes in fair value of the swaptions have been recorded in AOCI. Derivative Designated as Hedging Instruments - Fair Value Hedges Periodically, we enter into and designate fixed-to-floating interest rate swaps as fair value hedges. The purpose of these swaps is to manage interest rate risk by managing our mix of fixed-rate and variable-rate debt. These swaps involve the receipt of fixed-rate amounts for variable interest rate payments over the life of the swaps without exchange of the underlying principal amount. We also designate some of our cross-currency swaps as fair value hedges. The purpose of these contracts is to hedge foreign currency risk associated with changes in spot rates on foreign-denominated debt. For these hedges, we have elected to exclude the change in fair value of the cross-currency swaps related to both time value and cross-currency basis spread from the assessment of hedge effectiveness (the "excluded component"). Changes in the fair value of the cross-currency swaps attributable to changes in the spot rates on the final notional exchanges and changes in the value of the hedged assets due to changes in the spot rates are recorded in 'Foreign currency and derivative (loss) gain, net'. Changes in the fair value of the cross-currency swaps attributable to the excluded components are recorded to other comprehensive income and will be recognized in 'Foreign currency and derivative (loss) gain, net' on a systematic and rational basis, as net cash settlements and interest accruals on the respective cross currency swaps occur, over the remaining life of the hedging instruments. Derivatives Not Designated as Hedging Instruments We enter into foreign currency exchange swap agreements to reduce the effects of currency exchange rate fluctuations between the USD, our reporting currency, and GBP and EUR. These derivative contracts generally mature within one year and are not designated as hedge instruments for accounting purposes. As the currency exchange swap is not accounted for as a hedging instrument, the change in fair value is recorded in earnings through the caption entitled 'Foreign currency and derivative (loss) gain, net' in the consolidated statements of income and comprehensive income.

Net Income per Common Share	Net Income per Common ShareBasic net income per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted net income per common share is computed by dividing net income available to common stockholders, plus income attributable to dilutive shares and convertible common units for the period, by the weighted average number of common shares that would have been outstanding assuming the issuance of common shares for all potentially dilutive common shares outstanding during the reporting period. The following is a reconciliation of the denominator of the basic net income per common share computation to the denominator of the diluted net income per common share computation (shares in thousands): Three months ended Nine months ended 2023 2022 2023 2022 Weighted average shares used for the basic net income per share computation 709,165 617,512 681,419 604,464 Incremental shares from share-based compensation 378 355 360 342 Dilutive effect of forward ATM offerings — 90 350 30 Weighted average shares used for diluted net income per share computation 709,543 617,957 682,129 604,836 Unvested shares from share-based compensation that were anti-dilutive 309 68 243 37 Weighted average partnership common units convertible to common shares that were anti-dilutive 1,795 1,244 1,795 1,123 Weighted average forward ATM offerings that were anti-dilutive 535 563 460 188

Common Stock Incentive Plan	Common Stock Incentive Plan In March 2021, our Board of Directors adopted, and in May 2021, stockholders approved, the Realty Income 2021 Incentive Award Plan, or 2021 Plan. This note should be read in conjunction with the more complete discussion of our 2021 Plan included in note 17 to our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2022. The amount of share-based compensation costs recognized in 'General and administrative' in the consolidated statements of income and comprehensive income was $6.2 million and $5.1 million during the three months ended September 30, 2023, and 2022, respectively, and $20.2 million and $16.7 million during the nine months ended September 30, 2023, and 2022, respectively. A. Restricted Stock and Restricted Stock Units During the nine months ended September 30, 2023, we granted 220,970 shares of common stock under the 2021 Plan. This included 40,000 total shares of restricted stock granted to the independent members of our Board of Directors in connection with our annual awards in May 2023, 20,000 shares of which vested immediately and 20,000 shares of which vest in equal parts over a three-year service period. Our restricted stock awards granted to employees vest over a service period not exceeding four-years. During the nine months ended September 30, 2023, we also granted 15,065 restricted stock units, all of which vest over a four-year service period. As of September 30, 2023, the remaining unamortized share-based compensation expense related to restricted stock awards and units totaled $18.7 million, which is being amortized on a straight-line basis over the service period of each applicable award. The amount of share-based compensation is based on the fair value of the stock at the grant date. B. Performance Shares During the nine months ended September 30, 2023, we granted 193,868 performance shares, as well as dividend equivalent rights, to our executive officers. The performance shares are earned based on our Total Shareholder Return (TSR) performance relative to select industry indices and peer groups as well as achievement of certain operating metrics, and vest 50% on the first and second January 1 after the end of the three-year performance period, subject to continued service.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	For our consolidated subsidiaries whose functional currency is not the USD, we translate their financial statements into USD at the time we consolidate those subsidiaries’ financial statements. Generally, assets and liabilities are translated at the exchange rate in effect at the balance sheet date. The resulting translation adjustments are included in 'Accumulated other comprehensive income' ("AOCI") in the consolidated balance sheets. Certain balance sheet items, primarily equity and capital-related accounts, are reflected at the historical exchange rate. Income statement accounts are translated using the average exchange rate for the period. We and certain of our consolidated subsidiaries have intercompany and third-party debt that is not denominated in our functional currency. When the debt is remeasured to the functional currency of the entity, a gain or loss can result. The resulting adjustment is reflected in ' Foreign currency and derivative (loss) gain, net ' in the consolidated statements of income and comprehensive income. Intercompany accounts and transactions are eliminated in consolidation.
Principles of Consolidation	Principles of Consolidation. These consolidated financial statements include the accounts of Realty Income and all other entities in which we have a controlling financial interest. We evaluate whether we have a controlling financial interest in an entity in accordance with Accounting Standards Codification ("ASC") 810, Consolidation. Voting interest entities are entities considered to have sufficient equity at risk and which the equity holders have the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities in which we have a controlling financial interest, which we typically have through holding of a majority of the entity’s voting equity interests.
Principles of Consolidation, Variable Interest Entities	Variable interest entities ("VIEs") are entities that lack sufficient equity at risk or where the equity holders either do not have the obligation to absorb losses, do not have the right to receive residual returns, do not have the right to make decisions about the entity’s activities, or some combination of the above. A controlling financial interest in a VIE is present when an entity has a variable interest, or a combination of variable interests, that provides the entity with (i) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. An entity that meets both conditions above is deemed the primary beneficiary and consolidates the VIE. We reassess our initial evaluation of whether an entity is a VIE when certain reconsideration events occur. We reassess our determination of whether we are the primary beneficiary of a VIE on an ongoing basis based on current facts and circumstances.The portion of a consolidated entity not owned by us is recorded as a noncontrolling interest. Noncontrolling interests are reflected on our consolidated balance sheets as a component of equity. Noncontrolling interests that were created or assumed as part of a business combination or asset acquisition were recognized at fair value as of the date of the transaction
Reclassification	Reclassification . Certain prior period amounts have been reclassified to conform to the current year presentation.
Use of Estimates	Use of Estimates . The consolidated financial statements were prepared in conformity with U.S. GAAP, which requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Segment Reporting	Segment Reporting. We report our results in a single reportable segment, which reflects how our chief operating decision maker allocates resources and assesses our performance.
Income Taxes	Income Taxes. We have elected to be taxed as a REIT, under the Internal Revenue Code of 1986, as amended. We believe we have qualified and continue to qualify as a REIT. Under the REIT operating structure, we are permitted to deduct dividends paid to our stockholders in determining our taxable income. Assuming our dividends equal or exceed our taxable net income in the U.S., we generally will not be required to pay U.S. income taxes on such income. Accordingly, no provision has been made for federal income taxes in the accompanying consolidated financial statements, except for federal income taxes of our taxable REIT subsidiaries ("TRS"). A TRS is a subsidiary of a REIT that is subject to federal, state and local income taxes, as applicable. Our use of TRS entities enables us to engage in certain business activities while complying with the REIT qualification requirements and to retain any income generated by these businesses for reinvestment without the requirement to distribute those earnings. For our international territories, we are liable for taxes in the United Kingdom and Spain. Accordingly, provisions have been made for U.K. and Spain income taxes. Therefore, the income taxes recorded on our consolidated statements of income and comprehensive income represent amounts accrued or paid by Realty Income and its subsidiaries for U.S. income taxes on our TRS entities, city and state income and franchise taxes, and income taxes for the U.K. and Spain. Earnings and profits that determine the taxability of distributions to stockholders differ from net income reported for financial reporting purposes primarily due to differences in the estimated useful lives and methods used to compute depreciation and the carrying value (basis) of the investments in properties for tax purposes, among other things. We regularly analyze our various international, federal and state filing positions and only recognize the income tax effect in our financial statements when certain criteria regarding uncertain income tax positions have been met. We believe that our income tax positions would more likely than not be sustained upon examination by all relevant taxing authorities. Therefore, no provisions for uncertain tax positions have been recorded on our consolidated financial statements.
Lease Revenue Recognition and Accounts Receivable	Lease Revenue Recognition and Accounts Receivable. The majority of our leases are accounted for as operating leases. Under this method, leases that have fixed and determinable rent increases are recognized on a straight-line basis over the lease term. Any rental revenue contingent upon our client’s sales, or percentage rent, is recognized only after our client exceeds their sales breakpoint. Rental increases based upon changes in the consumer price indexes are recognized only after the changes in the indexes have occurred and are then applied according to the lease agreements. Contractually obligated rental revenue from our clients for recoverable real estate taxes and operating expenses are included in contractually obligated reimbursements by our clients, a component of rental revenue, in the period when such costs are incurred. Taxes and operating expenses paid directly by our clients are recorded on a net basis. Other revenue includes certain property-related revenue not included in rental revenue and interest income recognized on financing receivables for certain leases with above-market terms. We assess the probability of collecting substantially all of the lease payments to which we are entitled under the original lease contract as required under Topic 842, Leases . We assess the collectability of our future lease payments based on an analysis of creditworthiness, economic trends and other facts and circumstances related to the applicable clients. If we conclude the collection of substantially all lease payments under a lease is less than probable, rental revenue recognized for that lease is limited to cash received going forward, existing operating lease receivables, including those related to straight-line rental revenue, must be written off as an adjustment to rental revenue, and no further operating lease receivables are recorded for that lease until such future determination is made that substantially all lease payments under that lease are now considered probable. If we subsequently conclude that the collection of substantially all lease payments under a lease is probable, a reversal of lease receivables previously written off is recognized.
Concentration of Credit Risk	Concentration of Credit Risk. There were no clients who accounted for more than more than 10% of our total revenue for each of the nine months ended September 30, 2023, and 2022.

Schedule of Acquisitions	Below is a summary of our acquisitions for the nine months ended September 30, 2023: Number of Leasable Investment Weighted Initial Weighted Average Cash Lease Yield (1) Acquisitions - U.S. 802 14,730 $ 3,708.9 15.9 6.9 % Acquisitions - Europe 80 8,608 2,191.6 15.6 7.1 % Total acquisitions 882 23,338 $ 5,900.5 15.8 7.0 % Properties under development (2) 305 7,269 910.0 16.2 6.7 % Total (3) 1,187 30,607 $ 6,810.5 15.8 6.9 % (1) The initial weighted average cash lease yield for a property is generally computed as estimated contractual first year cash net operating income, which, in the case of a net leased property, is equal to the aggregate cash base rent for the first full year of each lease, divided by the total cost of the property. Since it is possible that a client could default on the payment of contractual rent (defined as the monthly aggregate cash amount charged to clients, inclusive of monthly base rent receivables), we cannot provide assurance that the actual return on the funds invested will remain at the percentages listed above. Contractual net operating income used in the calculation of initial weighted average cash lease yield includes approximately $3.7 million received as settlement credits as reimbursement of free rent periods for the nine months ended September 30, 2023. In the case of a property under development or expansion, the contractual lease rate is generally fixed such that rent varies based on the actual total investment in order to provide a fixed rate of return. When the lease does not provide for a fixed rate of return on a property under development or expansion, the initial weighted average cash lease yield is computed as follows: estimated cash net operating income (determined by the lease) for the first full year of each lease, divided by our projected total investment in the property, including land, construction and capitalized interest costs. (2) Includes £32.6 million of investments in four U.K. development properties and €25.9 million of investment in two Spain development properties, converted at the applicable exchange rates on the funding dates. (3) Our clients occupying the new properties are 89.7% retail, 10.0% industrial, and 0.3% other property types based on annualized contractual rent. Approximately 25% of the annualized contractual rent generated from acquisitions during the nine months ended September 30, 2023 is from investment grade rated clients, their subsidiaries, or affiliated companies.
