Credit Analysis: How Lenders Evaluate a Company's Ability to Service Debt
A mid-size industrial company carries $300M in total debt and generates $100M in EBITDA. A lender considering a new loan needs to answer two questions: can the company handle its current obligations, and how much room is left before it runs into trouble? Credit analysis is the framework for answering both.
Key takeaway: Leverage ratios measure how much debt a company carries relative to its earnings. Coverage ratios measure whether cash flow is large enough to service that debt. Together, they determine whether a borrower is investment grade or speculative, and how much additional debt the balance sheet can support.
The Company
Here is the industrial company's debt profile:
| Amount | |
|---|---|
| Revenue | $500M |
| EBITDA | $100M |
| Interest Expense | $20M |
| Total Debt | $300M |
| Cash | $50M |
| Required Principal Payments | $30M per year |
| Lease Payments | $5M per year |
EBITDA of $100M covers the $20M in annual interest, $30M in required principal payments, and $5M in lease obligations. How much cushion that leaves determines whether a lender says yes.
Leverage Ratios
Leverage ratios compare debt to earnings. The two standard credit measures are Debt/EBITDA and Net Debt/EBITDA.
Debt / EBITDA = $300M / $100M = 3.0x
The company carries three turns of debt relative to EBITDA. Each "turn" represents one year of earnings needed to repay the outstanding balance. At 3.0x, it would take three years of EBITDA to eliminate all debt, ignoring interest and taxes.
Net Debt / EBITDA = ($300M - $50M) / $100M = 2.5x
Net debt subtracts cash on hand because the company could use that cash to pay down debt immediately. The $50M cash balance reduces the effective leverage from 3.0x to 2.5x.
Both ratios answer the same question from slightly different angles: how much debt is the company carrying relative to its ability to generate cash? Lower is safer. Most investment-grade industrial companies operate between 1.5x and 3.0x. Above 4.0x, lenders start charging higher rates and imposing tighter covenants.
Coverage Ratios
Leverage ratios measure how much debt exists. Coverage ratios measure whether the company earns enough to service it.
Interest coverage is the most basic test. Credit analysts typically use EBITDA rather than EBIT because EBITDA better approximates the cash available to pay interest before capital allocation decisions:
Interest Coverage = EBITDA / Interest Expense
Interest Coverage = $100M / $20M = 5.0x
The company earns five dollars of EBITDA for every dollar of interest. A ratio above 3.0x is generally comfortable. Below 2.0x signals that the company has little margin for error.
Fixed charge coverage adds other mandatory payments that behave like interest:
Fixed Charge Coverage = EBITDA / (Interest + Leases)
Fixed Charge Coverage = $100M / ($20M + $5M) = 4.0x
Lease payments are contractual obligations that a company cannot skip without defaulting, just like interest. Including them gives a more complete picture of the fixed burden on cash flow.
The debt service coverage ratio (DSCR) goes further and includes required principal payments:
DSCR = EBITDA / (Interest + Principal)
DSCR = $100M / ($20M + $30M) = 2.0x
DSCR is the tightest test because it measures whether the company can cover both interest and principal from operating cash flow. A DSCR of 2.0x means the company generates twice what it needs. A DSCR below 1.0x means it cannot meet its obligations from earnings alone and must borrow, sell assets, or raise equity to stay current.
Rating Benchmarks
Credit rating agencies use leverage and coverage ratios as starting points for assigning ratings. The exact thresholds vary by industry, but the general pattern for industrial companies looks like this:
| Rating | Debt/EBITDA | Interest Coverage | Credit Quality |
|---|---|---|---|
| A | Below 2.0x | Above 8.0x | Strong investment grade |
| BBB | 2.0x to 3.0x | 4.0x to 8.0x | Lower investment grade |
| BB | 3.0x to 4.0x | 2.5x to 4.0x | Upper speculative grade |
| B | 4.0x to 6.0x | 1.5x to 2.5x | Speculative grade |
The company's 3.0x leverage and 5.0x interest coverage place it at the border of BBB and BB. That boundary matters: it separates investment grade from speculative grade. Many institutional investors can only hold investment-grade bonds, so a downgrade from BBB to BB shrinks the pool of potential buyers and raises the company's borrowing cost.
Stress Testing
The ratios above reflect current performance. Lenders also test what happens when earnings decline.
If EBITDA drops 25% from $100M to $75M while debt stays fixed:
| Ratio | Current | Stressed |
|---|---|---|
| Debt/EBITDA | 3.0x | 4.0x |
| Interest Coverage | 5.0x | 3.75x |
| DSCR | 2.0x | 1.5x |
At $75M in EBITDA, leverage rises to 4.0x and the company slides into BB territory. Interest coverage is still adequate at 3.75x, but DSCR at 1.5x is getting thin. The company can still meet its obligations, but the cushion is shrinking.
If EBITDA drops 50% to $50M:
| Ratio | Current | Stressed |
|---|---|---|
| Debt/EBITDA | 3.0x | 6.0x |
| Interest Coverage | 5.0x | 2.5x |
| DSCR | 2.0x | 1.0x |
At $50M in EBITDA, DSCR hits 1.0x. The company can barely cover interest and principal with nothing left for capital expenditures, dividends, or contingencies. Any further decline puts it into default territory.
The stress test reveals the company's debt capacity: the maximum debt load that remains serviceable through a realistic downturn. If the worst plausible scenario cuts EBITDA by 25%, the company can handle its current $300M in debt. If the worst case is a 50% drop, $300M is the limit and additional borrowing would be reckless.
Why Credit Analysis Matters
Credit analysis appears across corporate finance:
- Lending decisions: Banks run leverage and coverage ratios before approving loans. The ratios determine the interest rate, the amount, and the covenants attached to the credit agreement.
- LBO modeling: Private equity firms structure acquisitions with 4.0x to 6.0x leverage. Credit analysis determines how much debt the target can carry and still meet its obligations through a downturn.
- Capital structure: Management teams use credit analysis to decide how much debt to maintain. Operating at 3.0x leverage when the rating boundary is 3.0x leaves no room for error. Targeting 2.0x provides a cushion that preserves the investment-grade rating.
- Bond investing: Fixed-income investors compare credit ratios across issuers to identify which bonds compensate adequately for their risk. A BB bond paying 200 basis points over a BBB bond may or may not justify the incremental default risk.
Conclusion
Credit analysis measures a company's ability to carry and service its debt. Leverage ratios quantify the debt load, coverage ratios test whether cash flow can meet interest and principal obligations, and stress testing under downside scenarios reveals the true debt capacity.
