Is O a Buy? What to Consider in 2026

Short answer

The bull case for Realty Income Corporation (O) rests on Monthly dividend compounding with a 30-plus year growth streak: Realty Income has raised its dividend 135 times since its 1994 NYSE listing and declared 672 consecutive monthly dividends as of June 2026, with an annualized payout of $3.252 per share. Revenue (FY 2025) is ~$5.76 billion. If you believe that thesis holds, the real questions become position sizing and overlap, not timing. The main risk to that view: Interest rate sensitivity is the primary structural risk: O's share price is materially affected by movements in Treasury yields because investors compare its dividend yield against risk-free alternatives, and rising rates also increase borrowing costs that narrow acquisition spreads. Whether O is a buy comes down to whether you believe the thesis. This is informational, not a recommendation, and Walnut is not an investment adviser.

Realty Income Corporation (NYSE: O), founded in 1969 and headquartered in San Diego, California, is a real estate investment trust that acquires, owns, and manages freestanding, single-tenant commercial properties leased under long-term triple-net agreements. Under a triple-net lease, tenants bear property taxes, insurance, and maintenance costs, making revenue highly predictable; rental income forms over 99% of total revenue. As of Q1 2026, the portfolio spanned more than 15,600 properties leased to approximately 1,600 clients across 92 industries in all 50 U.S. states, the United Kingdom, and seven other European countries. Top tenants include essential and service-oriented businesses such as Walgreens, Dollar General, Dollar Tree, FedEx, Walmart, and CVS, which are considered relatively resistant to e-commerce disruption. The company earns its return by purchasing properties at cap rates meaningfully above its cost of capital and collecting contractual rent escalators over weighted average remaining lease terms of roughly nine years. Realty Income was founded by William E. Clark, Jr. and Evelyn Joan Clark and went public on the NYSE in 1994, branding itself as 'The Monthly Dividend Company.' It joined the S&P 500 Dividend Aristocrats index after surpassing 25 consecutive years of dividend increases, and as of June 2026 has declared 672 consecutive monthly dividends and 135 consecutive dividend increases since its NYSE listing. Sumit Roy serves as President and Chief Executive Officer. The company has grown substantially through acquisitions, including the 2024 merger with Spirit Realty, and has expanded into European markets, data centers, and a private capital platform that includes partnerships with institutions such as GIC. Full-year 2025 revenue was approximately $5.76 billion, up roughly 9% from 2024, and full-year 2025 AFFO per share was $4.28.

What's the case for buying O?

Monthly dividend compounding with a 30-plus year growth streak

Realty Income has raised its dividend 135 times since its 1994 NYSE listing and declared 672 consecutive monthly dividends as of June 2026, with an annualized payout of $3.252 per share. The monthly payment cadence appeals to income-focused investors who reinvest distributions, compounding returns over time. The 2026 AFFO guidance of $4.41 to $4.44 per share supports continued incremental increases at the current payout ratio.

Accelerating global acquisition pipeline at attractive spreads

Management raised its 2026 full-year investment guidance to approximately $9.5 billion, up from an initial $8 billion target, after deploying $2.8 billion in Q1 2026 alone at a 7.1% initial weighted-average cash yield. Acquisitions in both North America and Europe are generating positive spreads over the company's cost of capital, directly accreting to AFFO per share. The global net-lease addressable market is estimated at $14 trillion, giving O a long runway for external growth.

Scale and investment-grade balance sheet as competitive moat

Realty Income carries investment-grade credit ratings of A-/A3, among the strongest in the net-lease REIT sector, enabling it to issue debt at rates unavailable to smaller competitors. Net debt to Annualized Pro Forma Adjusted EBITDAre was 5.2x as of Q1 2026, within the company's stated long-term target range, and pro-rata liquidity exceeded $4.1 billion at year-end 2025. This financial flexibility allows O to sustain acquisitions through most credit cycles.

Diversification into Europe, data centers, and private capital

Beyond traditional U.S. retail, Realty Income has expanded into eight European countries, gaming properties (including Encore Boston Harbor), and data centers through a partnership with Digital Realty. A new private capital platform, including a U.S. Core Plus fund and GIC partnership, adds fee-based income and allows the company to co-invest in larger deals without proportional balance-sheet dilution. These initiatives diversify both geography and asset type, reducing single-market and single-sector concentration.

What are the risks to O?

Interest rate sensitivity is the primary structural risk: O's share price is materially affected by movements in Treasury yields because investors compare its dividend yield against risk-free alternatives, and rising rates also increase borrowing costs that narrow acquisition spreads. Tenant credit quality is a secondary concern, as a portion of credit losses has been traced to tenants acquired through recent M&A transactions, and retail bankruptcies or store-closure programs could pressure occupancy below its historically stable 98-plus percent level. Currency risk is growing as European investments expand, with local-currency debt only partially hedging revenue exposure. The stock trades at a GAAP P/E of roughly 52x (as of late June 2026), a significant premium to the broader REIT sector, meaning any disappointment in AFFO growth or guidance could weigh disproportionately on share price.

How is O valued? (as of 2026-06-27)

Revenue (FY 2025): ~$5.76 billion
AFFO per Share (FY 2025, full year): ~$4.28
AFFO per Share (Q1 2026, most recent quarter): ~$1.13 (+6.6% YoY)
2026 AFFO per Share Guidance (raised after Q1 2026): $4.41 to $4.44
Dividend Yield (annualized, as of late June 2026): ~5.2%
GAAP P/E Ratio (as of late June 2026): ~52x
Net Debt / Annualized Pro Forma Adjusted EBITDAre (Q1 2026): ~5.2x
Portfolio Occupancy (Q1 2026): ~98.5%

REITs are most meaningfully valued on AFFO rather than GAAP earnings, because depreciation charges make net income a poor proxy for cash generation; on a price-to-AFFO basis, O trades at roughly 14x forward AFFO using the midpoint of 2026 guidance and the late-June 2026 share price near $62, which is in line with its historical range but a premium to smaller net-lease peers. The ~5.2% dividend yield is among the highest O has offered in the past decade, reflecting both share-price compression from elevated interest rates and management's consistent payout increases. Investors weighing the valuation should note that the 2026 investment volume guidance of $9.5 billion, if executed at the recent ~7% cash yield, is the most aggressive acquisition posture in the company's history and could drive meaningful AFFO per share acceleration, but also increases sensitivity to any deterioration in capital market access.

How do you decide if O is a buy?

Rather than asking whether O is a buy in the abstract, it tends to help to answer four questions:

Thesis: do you believe the case above, and is it still true today?
Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
Overlap: check whether you already hold O indirectly through an index or sector ETF before adding more.

For the full picture, see the O stock guide (what the company does, the ETFs that hold it, similar stocks, and the themes it fits). In Walnut you can ask its AI about O against your real portfolio and see your actual exposure before deciding.

What does Realty Income do?

Realty Income is a net-lease REIT that owns over 15,600 freestanding commercial properties in the U.S. and eight European countries. It leases those properties to roughly 1,600 tenants across 92 industries under long-term triple-net leases, meaning tenants pay taxes, insurance, and maintenance. Rental income from those leases makes up virtually all of its revenue, and the company distributes most of that income to shareholders as monthly dividends.

Does Realty Income pay a dividend, and how often?

Yes. Realty Income pays a monthly dividend, which is unusual for a public company and is central to its identity as 'The Monthly Dividend Company.' As of June 2026, the monthly dividend is $0.2710 per share, an annualized rate of approximately $3.252, yielding roughly 5.2% at the prevailing share price. The company has declared 672 consecutive monthly dividends and has raised its dividend 135 times since its 1994 NYSE listing.

Is O a good stock to invest in right now?

That depends on an investor's goals, time horizon, and existing portfolio. O offers a roughly 5.2% dividend yield, a 30-plus year streak of consecutive increases, and above-average AFFO growth momentum heading into 2026. Against that, the stock carries meaningful interest-rate sensitivity, trades at a GAAP P/E near 52x, and competes with elevated Treasury yields for income-oriented capital. Neither characterization is universally right; the fit depends on individual circumstances.

Is Realty Income overvalued?

On a GAAP P/E basis, O trades at roughly 52x, well above the broader REIT sector average of roughly 27-28x. On a price-to-AFFO basis, the multiple is roughly 14x forward AFFO, which is closer to its historical norm and reflects that depreciation distorts GAAP earnings for real estate companies. Opinions among analysts are divided; 24 analysts have an average 'Hold' rating with a consensus price target near $67.90 as of late June 2026.
