With its stock down 33% over the past three months, it is easy to disregard PDF Solutions (NASDAQ:PDFS). However, the company's fundamentals look pretty decent, and long-term financials are usually aligned with future market price movements. Particularly, we will be paying attention to PDF Solutions' ROE today.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

AI is about to change healthcare. These 20 stocks are working on everything from early diagnostics to drug discovery. The best part - they are all under $10bn in marketcap - there is still time to get in early.

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 PDF Solutions is:

1.6% = US$4.1m ÷ US$246m (Based on the trailing twelve months to December 2024).

The 'return' is the yearly profit. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.02 in profit.

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. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

A Side By Side comparison of PDF Solutions' Earnings Growth And 1.6% ROE

As you can see, PDF Solutions' ROE looks pretty weak. Even when compared to the industry average of 12%, the ROE figure is pretty disappointing. Despite this, surprisingly, PDF Solutions saw an exceptional 43% net income growth over the past five years. We reckon that there could be other factors at play here. 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 PDF Solutions' net income growth with the industry, and pleasingly, we found that the growth seen by the company is higher than the average industry growth of 13%.

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. By doing so, they will have an idea if the stock is headed into clear blue waters or if swampy waters await. Is PDFS fairly valued?

Is PDF Solutions Efficiently Re-investing Its Profits?

PDF Solutions 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

Overall, we feel that PDF Solutions certainly does have some positive factors to consider. With a high rate of reinvestment, albeit at a low ROE, the company has managed to see a considerable growth in its earnings.
