Does TransAlta (TSE:TA) Have A Healthy Balance Sheet?

Warren Buffett famously said, 'Volatility is far from synonymous with risk.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. We can see that TransAlta Corporation (TSE:TA) does use debt in its business. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. If things get really bad, the lenders can take control of the business. 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. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

What Is TransAlta's Debt?

As you can see below, TransAlta had CA$3.90b of debt, at December 2021, which is about the same as the year before. You can click the chart for greater detail. However, because it has a cash reserve of CA$947.0m, its net debt is less, at about CA$2.96b.

How Healthy Is TransAlta's Balance Sheet?

We can see from the most recent balance sheet that TransAlta had liabilities of CA$1.93b falling due within a year, and liabilities of CA$4.70b due beyond that. Offsetting this, it had CA$947.0m in cash and CA$596.0m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by CA$5.09b.

When you consider that this deficiency exceeds the company's CA$3.67b market capitalization, you might well be inclined to review the balance sheet intently. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While we wouldn't worry about TransAlta's net debt to EBITDA ratio of 2.6, we think its super-low interest cover of 2.3 times is a sign of 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. One redeeming factor for TransAlta is that it turned last year's EBIT loss into a gain of CA$407m, over the last twelve months. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine TransAlta's ability to maintain a healthy balance sheet going forward.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So it is important to check how much of its earnings before interest and tax (EBIT) converts to actual free cash flow. Over the last year, TransAlta 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

To be frank both TransAlta's interest cover and its track record of staying on top of its total liabilities make us rather uncomfortable with its debt levels. But on the bright side, its conversion of EBIT to free cash flow is a good sign, and makes us more optimistic. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making TransAlta stock a bit risky. That's not necessarily a bad thing, but we'd generally feel more comfortable with less leverage. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. For example, we've discovered 1 warning sign for TransAlta that you should be aware of before investing here.
