Sanmina's (NASDAQ:SANM) stock is up by a considerable 16% over the past month. As most would know, fundamentals are what usually guide market price movements over the long-term, so we decided to look at the company's key financial indicators today to determine if they have any role to play in the recent price movement. Specifically, we decided to study Sanmina's ROE in this article.

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 Do You Calculate Return On Equity?

The formula for ROE is:

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

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

10% = US$238m ÷ US$2.4b (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 $0.10 in profit.

What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. 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.

Sanmina's Earnings Growth And 10% ROE

At first glance, Sanmina's ROE doesn't look very promising. Yet, a closer study shows that the company's ROE is similar to the industry average of 10%. On the other hand, Sanmina reported a moderate 14% net income growth over the past five years. Given the slightly low ROE, it is likely that there could be some other aspects that are driving this 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.

As a next step, we compared Sanmina's net income growth with the industry and found that the company has a similar growth figure when compared with the industry average growth rate of 14% in the same period.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. This then helps them determine if the stock is placed for a bright or bleak future. Is Sanmina fairly valued compared to other companies? These 3 valuation measures might help you decide.

Is Sanmina Making Efficient Use Of Its Profits?

Sanmina doesn't pay any regular dividends currently which essentially means that it has been reinvesting all of its profits into the business. This definitely contributes to the decent earnings growth number that we discussed above.

Conclusion

On the whole, we do feel that Sanmina has some positive attributes. Even in spite of the low rate of return, the company has posted impressive earnings growth as a result of reinvesting heavily into its business. With that said, the latest industry analyst forecasts reveal that the company's earnings are expected to accelerate.
