Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. Importantly, Knowles Corporation (NYSE:KN) does carry debt. But the more important question is: how much risk is that debt creating?

When Is Debt A Problem?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Knowles's Debt?

The image below, which you can click on for greater detail, shows that Knowles had debt of US$190.0m at the end of June 2025, a reduction from US$261.2m over a year. On the flip side, it has US$103.2m in cash leading to net debt of about US$86.8m.

How Strong Is Knowles' Balance Sheet?

The latest balance sheet data shows that Knowles had liabilities of US$167.2m due within a year, and liabilities of US$175.0m falling due after that. On the other hand, it had cash of US$103.2m and US$101.1m worth of receivables due within a year. So its liabilities total US$137.9m more than the combination of its cash and short-term receivables.

Given Knowles has a market capitalization of US$1.85b, it's hard to believe these liabilities pose much threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

Check out our latest analysis for Knowles

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Knowles's low debt to EBITDA ratio of 0.91 suggests only modest use of debt, the fact that EBIT only covered the interest expense by 5.0 times last year does give us pause. So we'd recommend keeping a close eye on the impact financing costs are having on the business. Also relevant is that Knowles has grown its EBIT by a very respectable 23% in the last year, thus enhancing its ability to pay down debt. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Knowles can strengthen its balance sheet over time. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Happily for any shareholders, Knowles actually produced more free cash flow than EBIT over the last three years. There's nothing better than incoming cash when it comes to staying in your lenders' good graces.

Our View

Knowles's conversion of EBIT to free cash flow suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. And that's just the beginning of the good news since its EBIT growth rate is also very heartening. Looking at the bigger picture, we think Knowles's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
