Investors are often guided by the idea of discovering 'the next big thing', even if that means buying 'story stocks' without any revenue, let alone profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like First Solar (NASDAQ:FSLR). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

How Quickly Is First Solar Increasing Earnings Per Share?

The market is a voting machine in the short term, but a weighing machine in the long term, so you'd expect share price to follow earnings per share (EPS) outcomes eventually. That means EPS growth is considered a real positive by most successful long-term investors. Recognition must be given to the that First Solar has grown EPS by 40% per year, over the last three years. That sort of growth rarely ever lasts long, but it is well worth paying attention to when it happens.

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 First Solar shareholders is that EBIT margins have grown from 14% to 34% in the last 12 months and revenues are on an upwards trend as well. Ticking those two boxes is a good sign of growth, in our book.

Are First Solar Insiders Aligned With All Shareholders?

We would not expect to see insiders owning a large percentage of a US$19b company like First Solar. But we do take comfort from the fact that they are investors in the company. Indeed, they have a considerable amount of wealth invested in it, currently valued at US$1.0b. Holders should find this level of insider commitment quite encouraging, since it would ensure that the leaders of the company would also experience their success, or failure, with the stock.

While it's always good to see some strong conviction in the company from insiders through heavy investment, it's also important for shareholders to ask if management compensation policies are reasonable. Our quick analysis into CEO remuneration would seem to indicate they are. The median total compensation for CEOs of companies similar in size to First Solar, with market caps over US$8.0b, is around US$13m.

First Solar offered total compensation worth US$7.7m 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. It can also be a sign of a culture of integrity, in a broader sense.

Should You Add First Solar To Your Watchlist?
