InterDigital (NASDAQ:IDCC) has had a great run on the share market with its stock up by a significant 14% over the last three months. Given the company's impressive performance, we decided to study its financial indicators more closely as a company's financial health over the long-term usually dictates market outcomes. Specifically, we decided to study InterDigital'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. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

Trump has pledged to "unleash" American oil and gas and these 15 US stocks have developments that are poised to benefit.

How Is ROE Calculated?

The formula for return on equity is:

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

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

42% = US$359m ÷ US$857m (Based on the trailing twelve months to December 2024).

The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.42 in profit.

Why Is ROE Important For Earnings Growth?

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