With its stock down 19% over the past three months, it is easy to disregard GMS (NYSE:GMS). However, stock prices are usually driven by a company’s financial performance over the long term, which in this case looks quite promising. In this article, we decided to focus on GMS' ROE.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Is ROE Calculated?

Return on equity can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for GMS is:

15% = US$219m ÷ US$1.5b (Based on the trailing twelve months to October 2024).

The 'return' is the income the business earned over the last year. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.15 in profit.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

GMS' Earnings Growth And 15% ROE

To start with, GMS' ROE looks acceptable. Further, the company's ROE is similar to the industry average of 17%. Consequently, this likely laid the ground for the impressive net income growth of 31% seen over the past five years by GMS. We reckon that there could also be other factors at play here. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio.

Next, on comparing with the industry net income growth, we found that GMS' growth is quite high when compared to the industry average growth of 23% in the same period, which is great to see.

Earnings growth is a huge factor in stock valuation. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous. Is GMS fairly valued? This infographic on the company's intrinsic value has everything you need to know.

Is GMS Using Its Retained Earnings Effectively?

GMS doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Conclusion

In total, we are pretty happy with GMS' performance. Specifically, we like that the company is reinvesting a huge chunk of its profits at a high rate of return. This of course has caused the company to see substantial growth in its earnings. Having said that, the company's earnings growth is expected to slow down, as forecasted in the current analyst estimates.
