Amphenol (NYSE:APH) has had a great run on the share market with its stock up by a significant 18% over the last three months. Since the market usually pay for a company’s long-term fundamentals, we decided to study the company’s key performance indicators to see if they could be influencing the market. In this article, we decided to focus on Amphenol's ROE.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. 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 Amphenol is:

23% = US$2.2b ÷ US$9.5b (Based on the trailing twelve months to September 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.23 in profit.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. 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.

Is Amphenol Efficiently Re-investing Its Profits?

Amphenol has a three-year median payout ratio of 25%, which implies that it retains the remaining 75% of its profits. This suggests that its dividend is well covered, and given the decent growth seen by the company, it looks like management is reinvesting its earnings efficiently.

Additionally, Amphenol has paid dividends over a period of at least ten years which means that the company is pretty serious about sharing its profits with shareholders.
