Investors know that Domino's is in the pizza business. But few are aware that the company generates most of its revenue from supply chain services. For context, in its fiscal third quarter of 2024, it had over $650 million in supply chain revenue, which was 60% of its total revenue.

Berkshire Hathaway initiated these new positions during the third quarter even as it cut back its holdings of big names like Apple and Bank of America.

People can debate their favorite toppings or preferred style of crust, but it's hard to find someone who doesn't love pizza. For more than 60 years, Domino's Pizza ( DPZ 1.68%) has translated that universal constant into a globally recognized brand and wildly successful franchise business.
