The earnings of Saudi Arabia’s giant oil company have long been a mystery, kept under wraps by the country’s government. But on Monday, Saudi Aramco opened its books, revealing that it generated $111.1 billion in net income last year, making it probably the world’s most profitable company by far.

It handily beat Apple ($59.5 billion in net income in 2018) and ran laps around other oil companies like Royal Dutch Shell ($23.9 billion) and Exxon Mobil ($20.8 billion). The disclosure reveals a company that is hugely profitable but also tightly bound to one country and the price of oil.

Aramco issued the financial data as it prepares to borrow up to $15 billion through a bond sale, in what could signal a more aggressive approach to capital-raising for both the company and Saudi Arabia, which is seeking to cut its dependence on oil and gas revenue.

The money will help finance Aramco’s $69 billion purchase of most of a state-owned petrochemical company from Saudi Arabia’s sovereign wealth fund, whose chairman is Crown Prince Mohammed bin Salman.
