I have no idea what numbers you are talking about. Progressives’s profit margins are 4% to 8% outside of 2018 to 2021. Currently under 5%.

And dividends/buybacks have nothing to do with profit margin. Those are not expenses, so that money is included in profit (aka net income). From which profit margin is calculated.

Revenue - expenses = profit.

Profit / revenue = profit margin.

Which is the same as net income / revenue = net (profit) margin
