AMT Data Centers & REITs 8/10 High Risk

8/10

↑ 6 → 8 over 22 weeks

Sector avg: 5.7/10

American Tower carries $38.9B in long-term debt, with $6.1B in scheduled principal maturities. Notably, the entire $6.1B maturity schedule falls within five years, creating a concentrated refinancing window. AMT shows a debt-to-equity ratio of 11.0x — well above the typical threshold for financial stress and cash covering only 0.3x of $6.1B in near-term maturities. DebtCanary scores AMT at 8/10, signaling elevated refinancing risk that warrants close monitoring.

Maturity Schedule

As of 2026-03-31 (latest SEC filing with maturity data). Debt actions taken after this date will only appear once SEC processes the relevant XBRL filing.

⚠ This schedule may be incomplete: some maturity buckets were excluded because they only appear in older filings. Totals and concentration are not computed from partial schedules.

Period	Amount Due	% of Total
Year 1 (0-12 months)	$6.1B	100.0%
Year 2 (12-24 months)	N/A	N/A
Year 3 (24-36 months)	N/A	N/A
Year 4 (36-48 months)	N/A	N/A
Year 5 (48-60 months)	N/A	N/A
Beyond 5 Years	N/A	N/A
Total Scheduled Maturities	$6.1B	100.0%

Why don't these totals match? Total scheduled maturities ($6.1B) falls short of balance-sheet long-term debt ($38.9B) by about 84%. The two figures come from different disclosures: the maturity schedule aggregates gross principal repayments from the debt footnote — typically including the current portion of long-term debt and sometimes finance leases — while balance-sheet long-term debt is a carrying value that excludes the current portion and is net of unamortized discounts, premiums, and issuance costs. They can also come from filings with different period-end dates (2026-03-31 vs 2026-03-31). Both numbers are shown exactly as reported to the SEC.

How This Score Was Computed

Weighted average of 3 scored components (raw 7.57, rounded to 8). Weights of skipped components are redistributed proportionally among those scored.

Component	Value	Sub-Score	Weight Used
Near-Term Maturity Concentration Parts of the maturity schedule only appear in older filings, so concentration would be measured against an incomplete total. Skipped rather than reported as a misleadingly high number.	N/A	—	not scored
Interest Coverage Ratio Show calculation Operating income / Interest expense Operating income: $4.8B Interest expense: $1.4B	3.47x	5/10	36%
Debt-to-Equity Ratio Show calculation Long-term debt / Stockholders' equity Long-term debt: $38.9B Stockholders' equity: $3.5B	11.04	9/10	36%
Cash Coverage of Near-Term Debt Show calculation Cash & equivalents / Debt due within 12 months Cash & equivalents: $1.6B Near-term debt: $6.1B	0.26x	9/10	29%
Cash Runway Only scored when a company is burning cash. Operating cash flow is positive (or unreported), so runway isn't a constraint.	N/A	—	not scored
