The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What moves the needle
- Occupancy, rents, and the cost of debt. Read on funds from operations and net asset value, because GAAP depreciation distorts the earnings, and a property downturn meets a balance sheet built on leverage. On its own account, the filing leans hardest on pricing power & competition, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- Funds from operations per share have compounded about 15% a year across the record. The dividend takes 72% of FFO, and is covered. Debt is 68% of assets, heavy for a REIT. The quality and location of the properties, the lease terms and occupancy, and the cost of the debt are what the 10-K settles, and no single ratio captures them.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Is it a good business?
- about $3.22 per shareNet income $74M + depreciation $189M − gains on sale $16M
What this means
GAAP net income with property depreciation added back, because the buildings a REIT charges against earnings usually hold or grow their value. This, not net income, is what a REIT is actually priced on. It is an approximation here: where a filing reports gains on property sales, we remove them, the way the NAREIT definition does.
- CoveredDividends $175M ÷ FFO $247MIndustry peers: median 72%
What this means
A REIT must distribute most of its taxable income, so a high payout is normal and the question is whether FFO covers it. Above 100%, the trust is funding the dividend with debt or asset sales, and a cut usually follows.
Is it sound?
- Debt / assets 67%HeavyTotal debt $3.4B ÷ assets $5.1BIndustry peers: median 43%
What this means
Every REIT runs on leverage; how much is the question. Heavy debt is what turns a property downturn into a wipeout, as 2008 showed, so a conservative balance sheet is part of the moat here, not a drag on it.
- Thin(operating income + depreciation) ÷ interest $162MIndustry peers: median 5.2×
What this means
How many times the property cash earnings cover the interest bill. Comfortable coverage is what lets a REIT refinance through a tight credit market instead of being forced to sell into one.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
In its own filing Named as a competitive risk
Its FY2025 10-K names artificial intelligence as a competitive threat.
“Our use of or inability to adopt and deliver new technological capabilities and enhancements in line with strategic objectives, including artificial intelligence and machine learning, may put us at a competitive disadvantage; cause us to miss opportunities to innovate, achieve efficiencies, or improve the customer expe…”
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat, and the company is using it that way.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.
| Fiscal year | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|
| 2020 | $2.8M | $3.5M | $204M |
| 2021 | $3.2M | $8.8M | $304M |
| 2022 | $4.1M | −$1.3M | $401M |
| 2023 | $1.6M | $2.1M | $407M |
| 2023 | $2.7M | $3.4M | $407M |
| 2024 | $4.8M | $3.9M | $344M |
Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years.
- Insider ownership13.7%
The stake all directors and executive officers hold together, per the 2025 proxy: skin in the game, the first thing Munger reads.
- CEO pay ratio132:1
What the chief earns for every dollar the median employee makes, per the 2025 proxy. A high ratio alone settles nothing; some businesses are genuinely top-heavy in scarce skill. A runaway figure is where Buffett starts asking whether the board is doing its job.
- Stock-based compensation$12M
The slice of the business handed to employees in shares this year, 2% of revenue, equal to 12% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.

The price
What a price has to assume.
What the price implies
price / FFOA REIT is priced on a multiple of its funds from operations (FFO), the cash it earns once the depreciation on its buildings is added back. Type today’s price; we show the multiple you would pay and the income and growth it implies.
$
The assumptions
FFO / share, delivered6%/yr’20→’25
The justified multiple is 1 ÷ (required return − growth), a perpetuity on FFO. At an 8% required return and 3% growth, a REIT is worth about 20× FFO.

FFO about $3.17 per share on 77M shares. The dials set the multiple they justify; your price sets the multiple you are paying. FFO here adds back depreciation and removes property-sale gains, the NAREIT method; it does not net out maintenance capex (AFFO), occupancy or lease terms, which the 10-K does.
