Most readers would already be aware that Sanmina's (NASDAQ:SANM) stock increased significantly by 23% over the past three months. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Particularly, we will be paying attention to Sanmina's ROE today.

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. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How To 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:

13% = US$293m ÷ US$2.3b (Based on the trailing twelve months to December 2023).

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 $0.13 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. 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.

Sanmina's Earnings Growth And 13% ROE

To begin with, Sanmina seems to have a respectable ROE. Further, the company's ROE compares quite favorably to the industry average of 10%. Probably as a result of this, Sanmina was able to see an impressive net income growth of 22% over the last five years. However, there could also be other causes behind 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.

Next, on comparing with the industry net income growth, we found that Sanmina's growth is quite high when compared to the industry average growth of 14% in the same period, which is great to see.

Earnings growth is a huge factor in stock valuation. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. Doing so will help them establish if the stock's future looks promising or ominous. Has the market priced in the future outlook for SANM?
