Most readers would already know that Gibraltar Industries' (NASDAQ:ROCK) stock increased by 8.7% over the past three months. Given that stock prices are usually aligned with a company's financial performance in the long-term, we decided to investigate if the company's decent financials had a hand to play in the recent price move. In this article, we decided to focus on Gibraltar Industries' ROE.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Do You Calculate Return On Equity?

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 Gibraltar Industries is:

11% = US$111m ÷ US$1.0b (Based on the trailing twelve months to September 2024).

The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.11 in profit.

Why Is ROE Important For Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. 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.

Gibraltar Industries' Earnings Growth And 11% ROE

To start with, Gibraltar Industries' ROE looks acceptable. Yet, the fact that the company's ROE is lower than the industry average of 18% does temper our expectations. However, the moderate 11% net income growth seen by Gibraltar Industries over the past five years is definitely a positive. So, there might be other aspects that are positively influencing earnings growth. 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. However, not to forget, the company does have a decent ROE to begin with, just that it is lower than the industry average. So this also provides some context to the earnings growth seen by the company.

Next, on comparing with the industry net income growth, we found that Gibraltar Industries' reported growth was lower than the industry growth of 16% over the last few years, which is not something we like to see.

Earnings growth is an important metric to consider when valuing a stock. It's important for an investor to know whether the market has priced in the company's expected earnings growth (or decline). By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. Is ROCK fairly valued?
