The newcomer in question is Latriece Watkins, now the CEO of Sam’s Club. Watkins is a three-decade Walmart veteran who started her latest role in February. In April, she took a quick trip from Bentonville to New York, where we met up at Walmart’s fashion office in Manhattan.

Sam’s Club is a segment CEO position within Walmart. But it’s a $96 billion business. If it were a standalone company on the Fortune 500, it would sit at No. 43—above Tesla and below Target. Watkins is running a business 10 times the size of what some Fortune 500 CEOs are running.

And most importantly, the Sam’s Club job has traditionally served as a proving ground for even bigger things to come. Alumni of the role have gone on to run all of Walmart, plus Target and Walgreens (Roz Brewer made that jump). The Sam’s Club division is run “at arm’s length” from the rest of Walmart, ex-Sam’s Club chief Brewer explained to me, and the position comes with a seat on Walmart’s executive committee—and exposure to its board of directors.

Those outside Walmart world are getting to know Watkins now for the first time, but she’ll likely be someone on their radar for years to come. That’s one reason she made her debut on the MPW list, both for the scope of her job today and its likelihood of leading to even bigger things in the years ahead.

Read my full story here to learn more about her and why the Sam’s Club job mints so many superstar CEOs.
