Tower Semiconductor's (NASDAQ:TSEM) stock is up by 6.9% 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. Specifically, we decided to study Tower Semiconductor's ROE in this article.

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 Is ROE Calculated?

ROE 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 Tower Semiconductor is:

19% = US$489m ÷ US$2.5b (Based on the trailing twelve months to June 2024).

The 'return' is the income the business earned over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.19.

What Is The Relationship Between ROE And Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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.

Tower Semiconductor's Earnings Growth And 19% ROE

To start with, Tower Semiconductor's ROE looks acceptable. On comparing with the average industry ROE of 12% the company's ROE looks pretty remarkable. This probably laid the ground for Tower Semiconductor's significant 42% net income growth seen over the past five years. We believe that there might also be other aspects that are positively influencing the company's earnings growth. For instance, the company has a low payout ratio or is being managed efficiently.

We then compared Tower Semiconductor's net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 21% in the same 5-year 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. Doing so will help them establish if the stock's future looks promising or ominous. Is Tower Semiconductor fairly valued compared to other companies? These 3 valuation measures might help you decide.

Is Tower Semiconductor Using Its Retained Earnings Effectively?

Tower Semiconductor doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Conclusion

In total, we are pretty happy with Tower Semiconductor's performance. Particularly, we like that the company is reinvesting heavily into its business, and at a high rate of return.
