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 Silicon Laboratories is:

4.8% = US$61m ÷ US$1.3b (Based on the trailing twelve months to September 2023).

The 'return' is the yearly profit. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.05 in profit.

What Is The Relationship Between ROE And 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. 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.

Silicon Laboratories' Earnings Growth And 4.8% ROE

On the face of it, Silicon Laboratories' ROE is not much to talk about. Next, when compared to the average industry ROE of 15%, the company's ROE leaves us feeling even less enthusiastic. However, the moderate 11% net income growth seen by Silicon Laboratories over the past five years is definitely a positive. So, there might 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.

Next, on comparing with the industry net income growth, we found that Silicon Laboratories' reported growth was lower than the industry growth of 30% over the last few years, which is not something we like to see.

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

Is Silicon Laboratories Making Efficient Use Of Its Profits?

Silicon Laboratories doesn't pay any dividend 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

In total, it does look like Silicon Laboratories has some positive aspects to its business. Specifically, its fairly high earnings growth number, which no doubt was backed by the company's high earnings retention. Still, the low ROE means that all that reinvestment is not reaping a lot of benefit to the investors.
