It's common for many investors, especially those who are inexperienced, to buy shares in companies with a good story even if these companies are loss-making. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' While a well funded company may sustain losses for years, it will need to generate a profit eventually, or else investors will move on and the company will wither away.

In contrast to all that, many investors prefer to focus on companies like Federal Signal (NYSE:FSS), which has not only revenues, but also profits. While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Quickly Is Federal Signal Increasing Earnings Per Share?

If a company can keep growing earnings per share (EPS) long enough, its share price should eventually follow. That makes EPS growth an attractive quality for any company. Shareholders will be happy to know that Federal Signal's EPS has grown 25% each year, compound, over three years. If the company can sustain that sort of growth, we'd expect shareholders to come away satisfied.

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth. The music to the ears of Federal Signal shareholders is that EBIT margins have grown from 13% to 15% in the last 12 months and revenues are on an upwards trend as well. That's great to see, on both counts.

Are Federal Signal Insiders Aligned With All Shareholders?

Owing to the size of Federal Signal, we wouldn't expect insiders to hold a significant proportion of the company. But thanks to their investment in the company, it's pleasing to see that there are still incentives to align their actions with the shareholders. Indeed, they have a considerable amount of wealth invested in it, currently valued at US$132m. This suggests that leadership will be very mindful of shareholders' interests when making decisions!

It means a lot to see insiders invested in the business, but shareholders may be wondering if remuneration policies are in their best interest. Our quick analysis into CEO remuneration would seem to indicate they are. Our analysis has discovered that the median total compensation for the CEOs of companies like Federal Signal with market caps between US$4.0b and US$12b is about US$8.0m.

Federal Signal offered total compensation worth US$6.9m to its CEO in the year to December 2023. That is actually below the median for CEO's of similarly sized companies. CEO remuneration levels are not the most important metric for investors, but when the pay is modest, that does support enhanced alignment between the CEO and the ordinary shareholders. Generally, arguments can be made that reasonable pay levels attest to good decision-making.

Should You Add Federal Signal To Your Watchlist?

If you believe that share price follows earnings per share you should definitely be delving further into Federal Signal's strong EPS growth. If that's not enough, consider also that the CEO pay is quite reasonable, and insiders are well-invested alongside other shareholders. This may only be a fast rundown, but the key takeaway is that Federal Signal is worth keeping an eye on. While we've looked at the quality of the earnings, we haven't yet done any work to value the stock. So if you like to buy cheap, you may want to check if Federal Signal is trading on a high P/E or a low P/E, relative to its industry.

There's always the possibility of doing well buying stocks that are not growing earnings and do not have insiders buying shares. But for those who consider these important metrics, we encourage you to check out companies that do have those features. You can access a tailored list of companies which have demonstrated growth backed by significant insider holdings.
