The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a 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. Importantly, ACS, Actividades de Construcción y Servicios, S.A. (BME:ACS) does carry debt. But the more important question is: how much risk is that debt creating?
Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. 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.
As you can see below, at the end of March 2025, ACS Actividades de Construcción y Servicios had €13.8b of debt, up from €10.5b a year ago. Click the image for more detail. However, it does have €10.9b in cash offsetting this, leading to net debt of about €2.88b.
According to the last reported balance sheet, ACS Actividades de Construcción y Servicios had liabilities of €7.16b due within 12 months, and liabilities of €15.6b due beyond 12 months. Offsetting these obligations, it had cash of €10.9b as well as receivables valued at €11.5b due within 12 months. So these liquid assets roughly match the total liabilities.
Having regard to ACS Actividades de Construcción y Servicios' size, it seems that its liquid assets are well balanced with its total liabilities. So while it's hard to imagine that the €15.5b company is struggling for cash, we still think it's worth monitoring its balance sheet.
See our latest analysis for ACS Actividades de Construcción y Servicios
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.
ACS Actividades de Construcción y Servicios has net debt worth 1.7 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 3.5 times the interest expense. While that doesn't worry us too much, it does suggest the interest payments are somewhat of a burden. We note that ACS Actividades de Construcción y Servicios grew its EBIT by 30% in the last year, and that should make it easier to pay down debt, going forward. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine ACS Actividades de Construcción y Servicios'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, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Happily for any shareholders, ACS Actividades de Construcción y Servicios actually produced more free cash flow than EBIT over the last three years. That sort of strong cash generation warms our hearts like a puppy in a bumblebee suit.
ACS Actividades de Construcción y Servicios'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. But truth be told we feel its interest cover does undermine this impression a bit. Looking at the bigger picture, we think ACS Actividades de Construcción y Servicios's use of debt seems quite reasonable and we're not concerned about it. While debt does bring risk, when used wisely it can also bring a higher return 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.
