Cars.com Inc. (NYSE:CARS) just reported some strong earnings, and the market reacted accordingly with a healthy uplift in the share price. However, our analysis suggests that shareholders may be missing some factors that indicate the earnings result was not as good as it looked.

How Do Unusual Items Influence Profit?

For anyone who wants to understand Cars.com's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit was reduced by US$18m due to unusual items. It's never great to see unusual items costing the company profits, but on the upside, things might improve sooner rather than later. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And, after all, that's exactly what the accounting terminology implies. Assuming those unusual expenses don't come up again, we'd therefore expect Cars.com to produce a higher profit next year, all else being equal.

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that Cars.com received a tax benefit of US$101m. This is meaningful because companies usually pay tax rather than receive tax benefits. We're sure the company was pleased with its tax benefit. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. In the likely event the tax benefit is not repeated, we'd expect to see its statutory profit levels drop, at least in the absence of strong growth. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On Cars.com's Profit Performance

In the last year Cars.com received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. But on the other hand, it also saw an unusual item depress its profit. Having considered these factors, we don't think Cars.com's statutory profits give an overly harsh view of the business. If you want to do dive deeper into Cars.com, you'd also look into what risks it is currently facing.
