Warren Buffett famously said, '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. As with many other companies Knowles Corporation (NYSE:KN) makes use of debt. But the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. If things get really bad, the lenders can take control of the business. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.

What Is Knowles's Net Debt?

The image below, which you can click on for greater detail, shows that at September 2024 Knowles had debt of US$225.0m, up from US$45.0m in one year. However, it also had US$92.6m in cash, and so its net debt is US$132.4m.

How Strong Is Knowles' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Knowles had liabilities of US$185.9m due within 12 months and liabilities of US$208.0m due beyond that. On the other hand, it had cash of US$92.6m and US$105.7m worth of receivables due within a year. So its liabilities total US$195.6m more than the combination of its cash and short-term receivables.

Given Knowles has a market capitalization of US$1.71b, it's hard to believe these liabilities pose much threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

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.

Looking at its net debt to EBITDA of 1.1 and interest cover of 3.8 times, it seems to us that Knowles is probably using debt in a pretty reasonable way. So we'd recommend keeping a close eye on the impact financing costs are having on the business. Unfortunately, Knowles saw its EBIT slide 3.0% in the last twelve months. If earnings continue on that decline then managing that debt will be difficult like delivering hot soup on a unicycle. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Knowles's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Over the last three years, Knowles actually produced more free cash flow than EBIT. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.

Our View

The good news is that Knowles's demonstrated ability to convert EBIT to free cash flow delights us like a fluffy puppy does a toddler. But, on a more sombre note, we are a little concerned by its interest cover. Looking at all the aforementioned factors together, it strikes us that Knowles can handle its debt fairly comfortably. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. 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.
