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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. Importantly, Enerflex Ltd. (TSE:EFX) does carry debt. But is this debt a concern to shareholders?
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. 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. 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. The first step when considering a company's debt levels is to consider its cash and debt together.
The image below, which you can click on for greater detail, shows that Enerflex had debt of US$648.0m at the end of September 2025, a reduction from US$787.0m over a year. On the flip side, it has US$64.0m in cash leading to net debt of about US$584.0m.
According to the last reported balance sheet, Enerflex had liabilities of US$909.0m due within 12 months, and liabilities of US$791.0m due beyond 12 months. Offsetting these obligations, it had cash of US$64.0m as well as receivables valued at US$687.0m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$949.0m.
Enerflex has a market capitalization of US$1.88b, 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.
View our latest analysis for Enerflex
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 1.4 and interest cover of 3.3 times, it seems to us that Enerflex is probably using debt in a pretty reasonable way. But the interest payments are certainly sufficient to have us thinking about how affordable its debt is. It is well worth noting that Enerflex's EBIT shot up like bamboo after rain, gaining 52% in the last twelve months. That'll make it easier to manage its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Enerflex's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.
Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Enerflex produced sturdy free cash flow equating to 62% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.
Happily, Enerflex's impressive EBIT growth rate implies it has the upper hand on its debt. But, on a more sombre note, we are a little concerned by its interest cover. All these things considered, it appears that Enerflex can comfortably handle its current debt levels. On the plus side, this leverage can boost shareholder returns, but the potential downside is more risk of loss, so it's worth monitoring the balance sheet. 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.
