Diageo  (FRA:GUI) Net Margin % Explanation

Although Net Income and Earnings-per-Share (EPS) are the most widely used parameter in measuring a company's profitability and valuation, it is the least reliable.

But the long term trend of the net margin is a good indicator of the competitiveness and health of the business.
