In his time running Apple, Tim Cook has been more like the “president of a country, not a company,” according to Deepwater Asset Management’s Gene Munster.

Cook’s predecessor, Steve Jobs, is considered one of the great product innovators in modern American history. But the role has been a very different one since Jobs stepped down in 2011, shortly before he died from cancer, and tapped Cook to take over.

With his run as CEO coming to an end on Sept. 1, Cook’s legacy will be one of tremendous value creation — Apple’s market cap increased from about $350 billion to $4 trillion on his watch — even if the company’s products were more evolutionary than revolutionary during his 15-year run.

That Cook, 65, is handing the reins to longtime hardware boss John Ternus is no great surprise. Multiple news outlets profiled Ternus in recent months, with The New York Times running a story in January headlined, “The Man Who Could Be Apple’s Next C.E.O.”
