Nike said Tuesday afternoon its longtime CEO Mark Parker is stepping down, effective January of next year. In a sign of the company's focus on digital, he will be replaced by John Donahoe, a Nike board member and the CEO of ServiceNow. Donahoe was formerly the CEO of eBay and is chairman of the board at PayPal. Nike shares seesawed in after-hours trading on the news and were last up less than 1%. ServiceNow shares tumbled more than 10%. Parker, who has been Nike's CEO since he took over from founder Phil Knight in 2006, will become the company's executive chairman, according to the press release. He has worked with Nike for four decades, including as vice president of global footwear and co-president. Parker said in an interview with CNBC's Wilfred Frost that Donahoe is "no stranger" at Nike and decidedly is "the best choice to come in." He said Donahoe should "enable this next level of growth," digitally, for the company. And he added Nike's board has spent "many months working on succession planning. ... This is not something that happens in a matter of weeks." He also said the decision wasn't prompted by recent doping allegations connected to Nike's Oregon Project.

At the end of September, Nike's head running coach, Alberto Salazar, was banned amid doping allegations, which reportedly included ties back to Parker. The New York Times reviewed emails from the U.S. Anti-Doping Agency that showed Parker had been briefed on Salazar's various experiments to use testosterone cream for track-and-field athletes. In an email to employees at the time, Parker said: "Nike did not participate in any effort to systematically dope any runners ever; the very idea makes me sick." He also said Nike looked into the allegations against Salazar and found no violations. "We are staying very close to the situation," Parker told CNBC on Tuesday. "We are in the midst of complex times." Nike's announcement came the same day Under Armour announced its CEO Kevin Plank will be stepping down from the role on Jan. 1. Under Parker's leadership, Nike has seen its stock surge and sales climb. But the company has also faced its share of corporate culture scandals and backlash over controversial marketing campaigns. In 2018, President Trevor Edwards, who many saw as Parker's likely successor one day, retired. The retirement came after complaints surfaced at Nike in March 2018, when a group of women presented Parker with a survey on gender discrimination. Edwards was blamed in the lawsuit for creating and exacerbating a "hostile work environment." Parker responded by restructuring his leadership team, which included ousting Edwards. Nike in 2018 admitted it failed in hiring and promoting women, and the company ousted at least 11 executives and announced raises for 7,000 employees after conducting an internal review of its pay practices. Parker apologized to employees at large in May. But the hurdles haven't stopped there. Nike, spearheaded by Parker, has had a history of using controversial marketing campaigns to boost its brand. In September 2018, it dropped a new ad campaign for the 30th anniversary of "Just Do It," featuring former San Francisco 49ers quarterback Colin Kaepernick. This pulled in a wave of responses, both for and against the commercial slot. But Nike's "Dream Crazy" campaign ultimately won the "outstanding commercial" award at the Creative Arts Emmy Awards this year, marking the first time a Nike commercial had won the award since 2002.
