In part, their business models overlap.

The key metrics we take into account for the infographic are:
Operating Margin

This measure is critical because it tells us the ability of a company to improve its operational efficiency over time. In fact, other metrics, like the Net Margin might be biased by factors like taxes and interest expenses, that are more tied to the company’s ability to find the right tax mix and financial mix. Instead, with the operating margin, we have a quick glans at the company’s operational efficiency.
Net Margin
It measures how good a company is in converting revenues in profits. This is a reasonable assessment of the overall business. However, when we refer to profits, it is crucial to understand the difference between cash. In fact, the income statement primary purpose is to understand the operations of an organization and not necessarily understand how much cash it has in the bank. For that, there is the cash flow statement. This metric is given by net income over net sales.
Return on Equity
Return on Capital Invested
Return on Assets
The return on assets tells you how much earnings a company generates from invested capital. Its formula is Net Income over Total Assets. It tells you how much profits are made for each additional dollar of capital invested in acquiring assets.
