The 400 richest people in America are worth a combined $5.4 trillion.

Some of that wealth stems from the Pittsburgh area.

Three people with ties to the Pittsburgh region made the annual list: Edward Stack (225), Thomas Tull (359) and Maggie Hardy (374).

Mt. Lebanon native Mark Cuban is also on the list at No. 230, although Forbes categorizes him under Texas because of his minority stake in the Dallas Mavericks. Forbes lists his net worth at $5.7 billion.

Former minority-stake holder of the Pittsburgh Steelers David Tepper comes in at No. 39 with a net worth of $21.3 billion. He is categorized under Florida.

A minimum net worth of $3.3 billion is required to be part of the list, according to Forbes.

Ed Stack

Stack’s net worth of $5.8 billion comes from Dick’s Sporting Goods, of which he is the executive chairman and largest individual shareholder. According to Forbes, his father Dick Stack started the sports retail company in 1948. Dick Stack used a $300 loan from his grandmother to start the business.

Dick’s Sporting Goods is now responsible for more than $13 billion in annual sales, according to Forbes. The retailer’s corporate office is in Coraopolis, PA. Stack resides in Sewickley.
