@fredom74 They have a net profit margin of around 34% after expenses and interest payments. Dividend payout on net profit is currently 60%+. Meaning they will pay 60%*34% or around 20% of revenue out as dividend.
They’ve also reduced their capex intensity over the last few years (as shown below). So they have sufficient cash flows to pay a high dividend while still deploying around 40% of net profit into new project CAPEX. The secret to all this is their large grid network which makes a lot of revenue plus very low operating costs, leading to gross margins of over 80%.
