Read the bridge before the payout ratio.
Adjusted funds from operations (AFFO) can exceed funds from operations (FFO) because the calculation includes additions as well as deductions. Subtracting recurring capital expenditure does not guarantee a smaller final number. Equinix’s 2025 reconciliation provides a complete example: 2,668 of FFO + 1,093 of net adjustments = 3,761 of AFFO, in USD millions, attributable to common stockholders.
In this lab, reproduce all 17 adjustments, explain why the capex deduction does not determine the direction of the result, and write down what you still need before assessing a dividend. The arithmetic can be done on paper. No account, live data or calculator is required.
- Check the reporting period, units and shareholder basis.
- Add the positive rows and the negative rows separately.
- Reconcile the result to reported AFFO, then explain the limits in your own words.
New to these measures? Read the FFO guide and AFFO guide first. They introduce the terminology; the tables below test it against a specific disclosure.
Start with the right net-income figure.
FFO is a supplemental REIT performance measure that adjusts GAAP accounting profit for specified real-estate items. It does not remove every noncash expense. Nareit’s framework also cautions against reading FFO as cash generated or as a sustainable dividend amount. Nareit’s definition and limitations, pp.1–5 ↗
For Equinix, the bridge begins with consolidated net income of 1,348. A positive 2 noncontrolling-interest adjustment gives 1,350 attributable to common stockholders. Real-estate depreciation and the FFO joint-venture adjustment then produce 2,668. The distinction between consolidated and common-stockholder income matters even when the difference is small.
| Reported row | USD millions |
|---|---|
| Net income | 1,348 |
| Net (income) loss attributable to non-controlling interests | 2 |
| Net income attributable to common stockholders | 1,350 |
| Real estate depreciation | 1,282 |
| (Gain) loss on disposition of real estate assets | 0 |
| Adjustments for FFO from unconsolidated joint ventures | 36 |
| FFO attributable to common stockholders | 2,668 |
DFB calculation: 1,348 + 2 = 1,350; then 1,350 + 1,282 + 0 + 36 = 2,668. The zero reflects the filing’s dash for this row and period; it is not a general assumption about asset sales.
All 17 adjustments, with their signs.
These are the issuer’s reported 2025 adjustments, in the filing’s order. Positive amounts increase AFFO; negative amounts reduce it. Both endpoints are attributable to common stockholders. Open the 10-K, p.61, FFO and AFFO reconciliation ↗
| Reported row | USD millions |

Reveal the addition and subtraction check
The positive adjustments total +1,455; the negative adjustments total −362. Net adjustment = 1,455 − 362 = +1,093. Starting FFO of 2,668 plus 1,093 equals 3,761, the disclosed AFFO. These are DFB calculations from the reported rows, not additional issuer measures.
A useful cross-check asks what happens if only capex is deducted. 2,668 − 284 = 2,384, which is 1,377 below reported AFFO. That shortcut omitted every other adjustment. The 1,377 is the net of the remaining 16 rows, not missing cash.
The reconciliation answers why AFFO is higher than FFO. It does not establish that every adjustment is economically harmless, nor that a larger denominator is the better choice for every comparison.
Turn the largest adjustments into questions.
1. What economic cost remains after an add-back?
The 498 share-compensation add-back, 568 non-real-estate depreciation add-back and 200 amortization add-back total 1,266. They explain much of the upward bridge. Removing an expense from a performance measure does not eliminate its economic effects.
For share compensation, inspect the share-count and compensation disclosures alongside per-share results. Dilution can affect the claim belonging to each share. For depreciation and amortization, ask how assets are maintained or replaced and how the accounting schedule differs from the timing of cash spending. Those are research questions, not findings that Equinix’s adjustments are improper.
2. Which timing adjustments move in each direction?
The installation-revenue adjustment is +20, the straight-line rent-expense adjustment is +5 and the contract-cost adjustment is −52. Together they reduce the measure by 27. A label containing “adjustment” does not tell you its sign. Copy the signed source value before deciding what it means.
Do not reuse another REIT’s straight-line rent convention automatically. This filing names a rent expense adjustment. The underlying accounting and sign need to be read from this issuer’s definition, not inferred from a generic template.
3. What spending is already deducted?
The −284 recurring-capex row is already inside reported AFFO. Equinix defines that category around extending asset lives and supporting current revenues. Its scope differs from the whole investment budget. Read the definition on p.60 together with the capital-spending and liquidity discussion that follows the reconciliations.
Subtracting the same recurring capex again would count it twice. Additional spending analysis may still be needed, but first identify what each cash-flow line includes and which deductions the issuer has already made.
What this calculation leaves unanswered.
AFFO is issuer-defined and non-GAAP. Equinix explains that similarly named measures at other companies may not be directly comparable. Rebuilding this table validates our transcription and arithmetic; it does not independently audit the company’s estimates or turn AFFO into cash flow.
Before drawing a dividend conclusion, examine operating cash flows, expansion projects, acquisitions, financing needs, debt maturities and the actual distribution record. Separate recognized earnings from cash timing, and aggregate amounts from per-share figures. A positive reconciliation difference alone establishes neither dividend safety nor a reporting problem.
This lab intentionally calculates no dividend payout ratio. Choosing the payout numerator requires its own evidence: paid or declared, common shareholders or a broader population, annual or annualized. The Realty Income filing lab shows why those distinctions change a ratio.
Historical scope: January 1–December 31, 2025 only. Subsequent quarters, current share prices, valuation and Equinix’s present dividend outlook are outside this exercise. Structural research, not investment advice.
Check your reasoning.
1. Does recurring capex force AFFO below FFO?
No. The full bridge contains additions and deductions. Here, +1,455 of additions exceeds −362 of deductions, including −284 of recurring capex. The net change is +1,093.
2. Why not add real-estate depreciation to FFO again?
The 1,282 of real-estate depreciation is already in the preceding net-income-to-FFO bridge. Adding it again would count the same adjustment twice. The separate 568 AFFO row concerns non-real-estate depreciation.
3. Can 3,761 be divided by a dividend per share?
No. 3,761 is an aggregate USD-million figure. Pair aggregate amounts with aggregate amounts, or use matching per-share figures for both sides. Check period and shareholder attribution as well as units.
4. Does an exactly balanced table prove the dividend is safe?
No. A balanced table checks transcription and arithmetic. It does not resolve future funding needs, the economic effects of excluded costs, debt access or management choices.
Carry a six-step checklist to the next filing.
- Record the period, currency, scale and shareholder basis.
- Find the issuer’s definition and complete reconciliation.
- Retain each row’s sign and verify both endpoints.
- Ask what the largest add-backs exclude economically.
- Avoid double-counting costs already deducted.
- Document the cash-flow, share-count and financing questions still open.
