ADC vs O: How Agree Realty Corporation and Realty Income Corporation Compare (2026)
Last updated August 2026
Short answer
ADC (Agree Realty Corporation) and O (Realty Income Corporation) share investment themes but are different businesses. The right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
ADC vs O: the tie-breaker metrics
Same yardstick, side by side (as of August 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.
| Metric | ADC | O | What it tells you |
|---|---|---|---|
| Forward P/E | 40.29 | 37.41 | Valuation on next year's expected earnings, the same yardstick for both. Lower is cheaper for that growth; higher means the market is paying up. |
| Trailing P/E | 41.83 | 52.35 | Valuation on the last 12 months. A big drop from trailing to forward means the market expects earnings to jump, so more growth is already in the price. |
| Beta | 0.47 | 0.73 | Volatility vs the market. Above 1 swings harder than the index; below 1 is steadier. Higher beta means bigger drawdowns to hold through. |
| Price vs 52-week range | 66% of range | 66% of range | Where today's price sits between the 52-week low and high. Near the high is momentum with less margin of safety; near the low is out of favor or a discount, depending on why. |
| Price / book | 1.54 | 1.52 | How much you pay over book value. Very high can signal an asset-light, high-return business or a rich price. |
Before you buy: how ADC and O affect your concentration
The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. ADC and O share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.
This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined ADC and O exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

What does Agree Realty Corporation (ADC) do?
Agree Realty Corporation (NYSE: ADC) is a real estate investment trust that acquires and develops freestanding, single-tenant retail properties net-leased to national and regional chains. Under net leases, tenants cover most property costs (taxes, insurance, and maintenance), which gives the REIT predictable rent streams and thin operating overhead. As of the end of 2025 the portfolio held roughly 2,674 properties across all 50 states, totaling about 55.5 million square feet, and was effectively fully leased at 99.7% occupancy. Investment-grade retailers generated close to 67% of annualized base rent, with top tenants including Walmart, Tractor Supply, Dollar General, Best Buy, and TJX, tilting the rent roll toward defensive, needs-based retail.
What does Realty Income Corporation (O) do?
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.
ADC vs O: how do they differ?
Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.
- ADC drivers: External growth engine; Investment-grade, defensive tenant base.
- O drivers: Monthly dividend compounding with a 30-plus year growth streak; Accelerating global acquisition pipeline at attractive spreads.
Which fits which kind of investor
A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: Interest-rate sensitivity is the dominant risk, since higher rates lift Agree's borrowing costs and make its dividend yield less competitive versus bonds, which can pressure the share price. For 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.
ADC or O: which should you pick?
ADC vs O: the full fundamentals
ADC. Agree trades at a premium multiple of AFFO relative to net-lease peers, roughly the high-teens on a price-to-AFFO basis, a level the market has long assigned to its balance-sheet quality and consistency. With 2026 AFFO guided around $4.56 and shares near $80, the valuation prices in reliable but unspectacular growth. Investors are largely paying for durability of income rather than a discount.
O. 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.
Headline figures (approximate, FEBRUARY 2026): ADC shows revenue (ttm) ~$715M, affo per share (2025) ~$4.32, affo per share (2026 guidance) ~$4.54 to $4.58, dividend (annualized) ~$3.20 (~4.4% yield); O shows 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.

FAQ
What is the difference between ADC and O?
+
Agree Realty Corporation (NYSE: ADC) is a real estate investment trust that acquires and develops freestanding, single-tenant retail properties net-leased to national and regional chains. 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. They show up together because they share investment themes, but they are different businesses, so the better fit depends on which thesis you are expressing.
Is ADC or O the better stock?
+
Neither is universally better; they suit different views and risk levels. Walnut is informational, not investment advice. Compare what each does, the tie-breaker metrics above, and the risks, then decide which fits your thesis and what you already own.
Which is cheaper, ADC or O?
+
On forward P/E (as of August 2026), ADC trades at 40.29x and O at 37.41x, so O is the cheaper of the two on next year's expected earnings. A lower multiple is not automatically the better buy: a richer valuation can be justified by faster growth, and a lower one can reflect real risk. Weigh the multiple against how fast each business is compounding.
Should you own both ADC and O?
+
Because they share themes, owning both concentrates you in that theme. That can be intentional (a focused bet) or accidental (less diversification than it looks). Walnut can show your combined exposure across both, and whether adding either over-concentrates you, before you buy.
What are the risks of ADC vs O?
+
ADC: Interest-rate sensitivity is the dominant risk, since higher rates lift Agree's borrowing costs and make its dividend yield less competitive versus bonds, which can pressure the share price. The company's growth depends on continually raising capital and buying properties at attractive spreads, so a prolonged period of high rates or a rich stock price can slow accretive growth. Tenant concentration is a factor, with a meaningful share of rent from a handful of large retailers whose fortunes are tied to physical, discretionary, and discount retail. A premium valuation leaves less margin for error if growth disappoints or if the net-lease sector re-rates lower. Broader retail disruption, e-commerce pressure on certain categories, and any single large-tenant bankruptcy could dent occupancy and rent. 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.
