How to Evaluate a Company's Debt Structure and Refinancing Risk
When a company blows up, the story almost always starts in the debt footnote, years before it makes headlines. Revenue growth and margins get the analyst attention, but the maturity schedule and rate structure of a company's borrowings often decide whether a rough year is survivable. A lot of corporate debt outstanding today was issued when rates were near historic lows, and as it comes due it has to be refinanced at whatever the market charges now. For some companies that repricing is a rounding error. For others it quietly rewrites the earnings picture.
The good news is that everything you need to assess this is public. It sits in the 10-K, mostly in a single footnote, and once you know what to look for you can work through it in under an hour. Here is how I do it.
Where the Real Information Lives
The balance sheet gives you two line items, current debt and long-term debt, which is nowhere near enough detail to work with. The detail lives in the notes to the financial statements. Pull the company's 10-K from EDGAR and find the note titled Long-Term Debt, Borrowings, or simply Debt. It lists every instrument outstanding: each bond and term loan, its principal, its interest rate, its maturity date, and usually the covenants attached to it.
Then read the liquidity and capital resources discussion in the MD&A. If management has real concerns about meeting obligations over the next twelve months, they are required to discuss them there. The language is heavily lawyered, so don't expect drama. Watch for a sentence like "we believe our sources of liquidity will be sufficient" followed by a long list of assumptions. The more assumptions, the more digging you should do.
Start With the Maturity Schedule
The most useful table in debt analysis is the maturity schedule, which companies present in the debt footnote: how much principal comes due in each of the next five years, plus one lump sum for everything after that.
You are looking for concentration. Say a company has $3 billion maturing in a single year and generates $500 million a year in free cash flow. It cannot repay that debt from operations, so it has to refinance, and whether that goes smoothly depends on its credit quality, market conditions at the time, and the terms lenders are willing to offer. The company controls none of those three things.
A well-managed structure spreads maturities out so no single year is make-or-break. A lumpy structure usually traces back to one big issuance, often acquisition financing, that was never staggered afterward. When you see a tower of debt due in one year, go read the history. If the company has been rolling the same maturity forward through repeated refinancings instead of paying it down, that tells you how the balance sheet is actually being run.
One habit worth building: compare the maturity ladder to free cash flow rather than EBITDA. EBITDA ignores capex, interest, taxes, and working capital, which are exactly the things that determine how much cash is genuinely available to retire debt.
Fixed Versus Floating Rate Exposure
Debt comes in two flavors. Fixed-rate debt has a locked coupon for its life. Floating-rate debt resets periodically off a benchmark, these days SOFR, which replaced LIBOR. The debt footnote almost always breaks down the mix.
The mix matters because floating-rate exposure moves interest expense without any change in the underlying business. Say a company carries $1 billion of floating-rate debt at 4% and the benchmark rises three points. Interest expense climbs by roughly $30 million a year, straight out of pre-tax income, while revenue and operations sit exactly where they were. If operating income is $150 million, that repricing just consumed a fifth of it.
Many companies hedge part of this exposure with interest rate swaps, which effectively convert floating debt to fixed. Hedges are disclosed in the derivatives footnote. If you see a large floating-rate balance, check whether swaps cover it, how much of it, and when the swaps expire. A hedge that rolls off next year is deferred exposure, and companies are rarely eager to point that out.
Keep in mind that fixed-rate debt only protects you until it matures. A company with entirely fixed-rate debt at low coupons still reprices eventually, just on the maturity schedule instead of every quarter. So the rate mix and the maturity ladder have to be read together.
Covenants and What a Waiver Tells You
Covenants are the conditions lenders attach to keep a borrower on a short leash. The common ones are a maximum leverage ratio (total debt to EBITDA), a minimum interest coverage ratio, minimum liquidity levels, and restrictions on additional borrowing, asset sales, and dividends.
Breaching a covenant is a technical default, which typically gives lenders the right to demand immediate repayment. In practice they rarely pull that trigger right away. What usually happens is the company negotiates a waiver or an amendment and pays for it through higher spreads, tighter terms, or fees. Either way, financial flexibility shrinks at exactly the moment the business needs it most.
The disclosure to look for is simple. A statement that the company was in compliance with all covenants as of the reporting date is boilerplate, and fine. Any mention of a waiver, an amendment to covenant levels, or expected compliance hedged with caveats deserves attention. Companies do not amend covenants for fun. If the levels were loosened recently, the old levels were about to be breached.
If you want to go a level deeper, the actual credit agreements are filed as exhibits on EDGAR. Read the definitions section. "EBITDA" in a credit agreement is a negotiated term full of add-backs, and the covenant is measured against that version rather than the number in the earnings release.
The Revolver Is the Real Liquidity Number
Most companies maintain a revolving credit facility, which works like a corporate credit card: committed capacity they can draw and repay as needed. The 10-K discloses the facility size, the amount drawn, and any letters of credit issued against it. Available liquidity is what remains after both.
A company with a $1 billion revolver that has drawn $800 million has only $200 million of headroom left. Now suppose it faces a $500 million maturity in the next twelve months and generates $300 million in free cash flow. The arithmetic does not close without new financing or an asset sale, and both of those are easiest to arrange when you need them least.
This check matters most for cyclical businesses. In a downturn, revenue and cash flow fall at the same time credit markets tighten, so a company that enters the cycle with its revolver mostly drawn has very few moves left. For cyclical names, revolver headroom at the top of the cycle is the buffer the company will actually live on at the bottom, so I look at it early.
Also check whether the revolver carries its own covenants, including springing covenants that only activate once drawings pass a certain threshold. Capacity on paper can be smaller in practice if drawing it would trip a test.
Secured Versus Unsecured Debt
Secured debt is backed by specific collateral: real estate, equipment, receivables, sometimes the whole company through a blanket lien. Unsecured debt is backed by the general credit of the business. In a bankruptcy, secured creditors get paid from their collateral first, unsecured creditors split whatever remains, and equity holders stand behind all of them.
As an equity investor you care about this for two reasons. First, a heavily secured capital structure leaves less residual value for everyone junior in a distress scenario. Second, and more practically, a company whose assets are already pledged has little left to offer new lenders. Unencumbered assets are borrowing capacity held in reserve. When a struggling company issues secured debt for the first time, it is often because the unsecured market has closed to it, and the existing unsecured bonds just became riskier.
Putting It Together
Once you have the pieces, the overall read usually falls into one of three buckets.
- Low risk: maturities spread across many years, mostly fixed-rate debt, plenty of undrawn revolver, comfortable covenant headroom, investment-grade rating.
- Moderate risk: some concentration in the next two or three years, meaningful floating-rate exposure, adequate but not abundant liquidity, covenants with room but not much of it.
- High risk: large maturities inside twelve months, heavy floating exposure or hedges rolling off, a mostly drawn revolver, tight covenant compliance, high-yield or unrated credit.
A high-risk company facing a maturity has three options, all bad in different ways. It can refinance at much higher rates and watch margins compress. It can sell assets, which shrinks the business that has to service the remaining debt. Or it can issue equity, usually at a depressed price precisely because the market can see the problem. Leveraged companies rarely fail because of any one of these. They fail when they are forced into all three at once.
A Checklist You Can Run in an Hour
Work through these questions, in order, for any company you are serious about:
- What is total debt, and what is debt to EBITDA? Then sanity-check leverage against free cash flow.
- When does the debt mature, year by year? Are there concentrations?
- What is the fixed versus floating mix, and are the floating pieces hedged? When do the hedges expire?
- What are the key covenants, and how much headroom exists against each?
- How much revolver capacity is genuinely available after draws and letters of credit?
- What is the credit rating, and which direction has it moved recently?
- Does operating income cover interest expense with room to spare?
- If everything maturing in the next two years had to be refinanced at today's rates, what would happen to earnings?
That last question is the stress test that matters most, and it takes five minutes with the debt footnote open. Take the maturing principal, apply a current market rate for a comparable issuer (the yield on the company's own traded bonds is a decent proxy), and compare the new interest expense to the old. Plenty of companies look fine at the coupons they locked in years ago and look very different at the rates they would pay today. Running that arithmetic on every leveraged company you analyze will surface refinancing risk well before it shows up in the price, and it costs you nothing but a footnote and a calculator.
