With its stock down 8.4% over the past week, it is easy to disregard Penumbra (NYSE:PEN). But if you pay close attention, you might find that its key financial indicators look quite decent, which could mean that the stock could potentially rise in the long-term given how markets usually reward more resilient long-term fundamentals. In this article, we decided to focus on Penumbra's ROE.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To 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 Penumbra is:

1.2% = US$14m ÷ US$1.2b (Based on the trailing twelve months to June 2024).

The 'return' is the amount earned after tax over the last twelve months. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.01.

Why Is ROE Important For 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 all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

Penumbra's Earnings Growth And 1.2% ROE

It is hard to argue that Penumbra's ROE is much good in and of itself. Not just that, even compared to the industry average of 11%, the company's ROE is entirely unremarkable. However, the moderate 16% net income growth seen by Penumbra over the past five years is definitely a positive. Therefore, the growth in earnings could probably have been caused by other variables. 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 Penumbra's growth is quite high when compared to the industry average growth of 11% in the same period, which is great to see.

The basis for attaching value to a company is, to a great extent, tied to its earnings growth. 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. Has the market priced in the future outlook for PEN?
