Is Siltronic (ETR:WAF) Using Too Much Debt?

Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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, Siltronic AG (ETR:WAF) does carry debt. But should shareholders be worried about its use of debt?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. When we think about a company's use of debt, we first look at cash and debt together.

What Is Siltronic's Net Debt?

You can click the graphic below for the historical numbers, but it shows that as of September 2023 Siltronic had €796.5m of debt, an increase on €368.0m, over one year. However, it also had €506.1m in cash, and so its net debt is €290.4m.

How Healthy Is Siltronic's Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Siltronic had liabilities of €558.3m due within 12 months and liabilities of €1.64b due beyond that. Offsetting this, it had €506.1m in cash and €228.4m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by €1.46b.

Siltronic has a market capitalization of €2.72b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Siltronic has net debt of just 0.62 times EBITDA, suggesting it could ramp leverage without breaking a sweat. But the really cool thing is that it actually managed to receive more interest than it paid, over the last year. So there's no doubt this company can take on debt while staying cool as a cucumber. In fact Siltronic's saving grace is its low debt levels, because its EBIT has tanked 39% in the last twelve months. When a company sees its earnings tank, it can sometimes find its relationships with its lenders turn sour. 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 Siltronic'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.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, Siltronic burned a lot of cash. While that may be a result of expenditure for growth, it does make the debt far more risky.

Our View

To be frank both Siltronic's conversion of EBIT to free cash flow and its track record of (not) growing its EBIT make us rather uncomfortable with its debt levels. But on the bright side, its interest cover is a good sign, and makes us more optimistic. Looking at the bigger picture, it seems clear to us that Siltronic's use of debt is creating risks for the company. If all goes well, that should boost returns, but on the flip side, the risk of permanent capital loss is elevated by the debt. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
