List all their maturities
Listing all 80+ individual bond tranches would be an overwhelming wall of text, so Wall Street evaluates Comcast's debt by looking at its annual maturity schedule.
Here is exactly how much principal comes due each year, based on their latest annual filings (heading into 2026):
| Year | Fixed-Rate Debt | Variable-Rate Debt | Total Principal Due |
|---|---|---|---|
| 2026 | $5.90 billion | $0.00 | $5.90 billion |
| 2027 | $5.00 billion | $0.00 | $5.00 billion |
| 2028 | $5.70 billion | $0.00 | $5.70 billion |
| 2029 | $4.80 billion | $0.10 billion | $4.90 billion |
| 2030 | $4.80 billion | $0.10 billion | $4.90 billion |
| 2031 and beyond | $75.40 billion | $3.00 billion | $78.40 billion |
(Note: The total principal due is roughly $104.8 billion. The official balance sheet figure of ~$94.6 billion is slightly lower because it accounts for unamortized discounts, issuance costs, and short-term commercial paper fluctuations.)

What makes up the "2031 and beyond" bucket?
The vast majority of Comcast's debt doesn't mature for decades. Instead of a few massive loans, this $78.4 billion is chopped up into dozens of individual corporate bonds sold to institutional investors.
Some of the largest individual "mega bonds" sitting in that far-off bucket include:
- The 2056 Note: A massive $6.0 billion bond issued at an incredibly low 2.937% interest rate, not due until November 1, 2056.
- The 2051 Note: A $4.98 billion bond at 2.887%, due in November 2051.
- The 2063 Note: A $4.0 billion bond at 2.987%, stretching all the way out to November 2063.
By locking in billions of dollars at sub-3% interest rates for 30 to 40 years, Comcast effectively inflation-proofed a huge chunk of its capital structure.
