Is Coherent (NYSE:COHR) A Risky Investment?

David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the permanent loss of capital.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Coherent Corp. (NYSE:COHR) makes use of debt. But the more important question is: how much risk is that debt creating?

Why Does Debt Bring Risk?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. When we think about a company's use of debt, we first look at cash and debt together.

What Is Coherent's Debt?

The image below, which you can click on for greater detail, shows that at June 2023 Coherent had debt of US$4.31b, up from US$2.30b in one year. However, because it has a cash reserve of US$821.6m, its net debt is less, at about US$3.49b.

How Healthy Is Coherent's Balance Sheet?

According to the last reported balance sheet, Coherent had liabilities of US$1.08b due within 12 months, and liabilities of US$5.40b due beyond 12 months. Offsetting these obligations, it had cash of US$821.6m as well as receivables valued at US$901.5m due within 12 months. So it has liabilities totalling US$4.76b more than its cash and near-term receivables, combined.

This deficit is considerable relative to its market capitalization of US$5.65b, so it does suggest shareholders should keep an eye on Coherent's use of debt. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Coherent's debt to EBITDA ratio (3.3) suggests that it uses some debt, its interest cover is very weak, at 1.3, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Even more troubling is the fact that Coherent actually let its EBIT decrease by 9.7% over the last year. If it keeps going like that paying off its debt will be like running on a treadmill -- a lot of effort for not much advancement. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Coherent can strengthen its balance sheet over time. 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 the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Coherent recorded free cash flow worth 61% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

We'd go so far as to say Coherent's interest cover was disappointing. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Overall, we think it's fair to say that Coherent has enough debt that there are some real risks around the balance sheet. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet. We've identified 3 warning signs with Coherent (at least 1 which is potentially serious) , and understanding them should be part of your investment process.
