Because Equinix's free cash flow is negative, this analysis substitutes AFFO (Adjusted Funds From Operations), the REIT-standard cash-flow metric, for the usual free-cash-flow reverse DCF. On that basis, Equinix's stock price implies about 9.8% annual AFFO growth for the next ten years — actually lower than the company's 11.3% actual 5-year AFFO growth rate, an unusually mild ask compared to most reverse DCFs.
At its current price, EQIX implies ~9.8% annual AFFO growth for the next 10 years, discounted at 9%.
Equinix's actual 5-year AFFO growth has averaged 11.3% a year.
Why this uses AFFO, not free cash flow
Required growth vs. historical growth
Required growth from the reverse-AFFO model below. Historical CAGRs from 10-K AFFO reconciliation tables: AFFO grew from $2,451M (FY2021) to $2,714M (FY2022) to $3,019M (FY2023) to $3,356M (FY2024) to $3,761M (FY2025).
Sensitivity: what if the discount rate moves?
| Discount rate | Required growth | Note |
|---|---|---|
| 8% | 7.4% | Below historical AFFO growth |
| 9% (base case) | 9.8% | Still below historical AFFO growth |
| 10% | 12.0% | Roughly matches historical growth |
| 12% | 15.9% | Well above historical growth |
A single percentage point of discount-rate increase (9% to 10%) is enough to push the required growth rate above Equinix's actual historical AFFO pace — the "mild ask" conclusion above depends on treating 9% as the appropriate discount rate for a REIT that is now taking on meaningfully more leverage.
What would move this number
- Swapping the AFFO base from FY2025 ($3,761M) to the 3-year average ($3,379M) raises the required growth rate from 9.8% to 11.2% — essentially matching Equinix's own historical CAGR exactly. Using the most recent year as the base, as this analysis does, is what makes the market's ask look mild rather than merely in line.
- Using a 12% discount rate instead of 9% (arguably reasonable given Equinix's rising leverage) pushes the required growth rate to 15.9% — above both historical AFFO growth rates, flipping the picture from "modest ask" to "aggressive ask."
- Using the standard FCF-based approach instead of AFFO would make this model unsolvable outright: 3-year average FCF is -$499M, and there's no defined growth rate that compounds a negative starting cash flow toward a positive target value.

Why FCF normalization was abandoned: this site's standard rule falls back to a 3-year FCF average when the latest figure deviates more than ±40% from it. Equinix's 3-year average FCF is itself negative (-$499M), which makes the standard reverse-DCF model unsolvable regardless of which FCF period is chosen — AFFO was substituted instead, as documented above.
Model: AFFO is assumed to grow at a constant annual rate g for 10 years, then at a 2.5% terminal rate thereafter, solved by bisection for the value of g that equates present value to today's market capitalization ($103,052M). Net debt is not added, because AFFO — unlike FCF — already reflects cash flow after interest expense, so it's compared directly against equity value (market cap) rather than enterprise value.
Historical CAGR check: 5-yr AFFO CAGR = ($3,761M ÷ $2,451M)^(1/4) − 1 = 11.3%. 3-yr AFFO CAGR = ($3,761M ÷ $2,714M)^(1/3) − 1 = 11.5%.
The fine print
- This isn't a fair-value price target — it only shows what the current price already assumes.
- This analysis substitutes AFFO for free cash flow because standard FCF is negative — a deliberate deviation from this site's normal reverse-DCF methodology, explained above.
- AFFO doesn't subtract the growth capex now being funded by rising debt (total debt up 55% since 2021) — a real risk this specific calculation doesn't capture.
- Change the discount rate or the AFFO base period, and the answer moves meaningfully — see the sensitivity table above.
- A reverse DCF (or reverse-AFFO model) shows what the market currently expects — it does not say what the stock is "worth."
- Any investment decision, and its outcome, is your own responsibility.
Frequently asked questions
Why doesn't this analysis use free cash flow like usual?
Equinix's free cash flow is negative — -$1,394M in FY2025 and -$499M averaged over the past three years — because it's spending heavily on new AI-ready data-center construction. A negative base makes the standard model unsolvable, so this analysis uses AFFO (Adjusted Funds From Operations) instead, the metric REITs and their investors standardly use to judge dividend-paying capacity.
What growth rate does EQIX's stock price assume?
At today's price, Equinix's stock is pricing in about 9.8% annual AFFO growth for the next ten years, at a 9% discount rate — actually below the company's 11.3% actual 5-year AFFO growth rate.
What share price was used for this analysis?
This analysis used $1,044.41, as of the Aug 28, 2026 close.
