Staggering Profit Margins of 10 French-Listed Companies on the Stock Market

Are you a stock-picking enthusiast looking to invest in the stock market? Discover our 2026 Top 10 of French-listed companies that show the strongest net profit margins relative to their revenue, ranging from 13% to 49%.

How to calculate a company’s profit margin?

The profit margin is calculated by dividing net profit by revenue over a given period.

Example: Company A generates a revenue of 10,000,000 euros. After all its charges are paid, it has 800,000 € of net profit (= net income).

Profit margin calculation: net profit (800,000 €) / revenue (10,000,000 €) = 0.08. Company A therefore has a profit margin of 8.00%.

It is important to clearly understand the difference between profit margin and earnings yield (per-share profitability).

If we keep the example of Company A which would be valued on the stock market at 18,000,000 euros, with 300,000 shares outstanding, its stock price would be 60 € per share.

It is then possible to calculate earnings per share. In the case of Company A:

800,000 € of profit / 300,000 shares outstanding = 2.67 € earnings per share (EPS). Therefore, the profitability of Company A’s shares is (2.67 € EPS / 60 € share price) = 4.45%.

In conclusion, Company A generates a profit margin of 8.00% and, at its stock price of 60 €, has an earnings yield of 4.45% at its current price.

If its stock price moves up or down, the earnings yield will fall or rise. Calculations will need to be readjusted at future earnings announcements.

How Café de la Bourse produced this Top 10 2026 of French-listed companies with the highest profit margins?

Our ranking was prepared using the annual financial data from the last five fiscal years.

To compile this ranking of the 10 French companies with the highest profit margins on revenue, we excluded companies with the following typologies:

• listed real estate companies that inherently have high net margins because their revenues come from rents (thus the majority of their revenue); for this type of company, it is more relevant to compare profit to the value of the real estate portfolio;
• investment companies, holding companies, banks, and private equity firms (companies investing in non-listed investments) which, likewise, have profiles for which profit margins must be understood according to specific approaches.

Thus, we focused on companies with commercial and/or industrial activities for which profit margin concepts are meaningful performance indicators.

We also restated years where income statements showed exceptional gains from asset disposals or results from discontinued operations. Indeed, these events do not correspond to profits from the ongoing activities of the companies concerned and should therefore be excluded to maintain a relevant approach to profit margins.

Finally, to maintain a minimum-size threshold, we kept companies with a market capitalization equal to or greater than 1 billion euros, and the following criterion: no year with notable negative net income (loss) in the last five years.
