He's stepping down from Starbucks on June 26. "But I'm a long way from making any decisions about the future".
Schultz added that he has for some time been "deeply concerned about our country - the growing division at home and our standing in the world". But investors have been underwhelmed by the company's new outlook, with the shares falling about 11 per cent in the previous year.
Schultz, who joined Starbucks as director of operations and marketing in 1982 and as CEO oversaw its 1992 initial public offering, announced in December 2016 that he would step down from the position but would remain with the company as Chairman.
He is facing cooler growth in Starbucks' dominant US market and intense competition from rivals - ranging from high-end coffee shops to more affordable fast-food chains - as the company undertakes a massive expansion project in China. In his new role as executive chairman, Schultz was focused on the company's push to develop a higher-end brand so it could compete with so-called "third wave" chains like Blue Bottle, as well as "experiential destinations" to draw in customers in a changing retail landscape.
"I write to you today enjoying a French Press of my favorite coffee, aged Sumatra, and feeling so many emotions", Schultz wrote in a letter to Starbucks employees. And he bought Starbucks from its original owners in 1987 with the support of Bill Gates Sr, the father of Microsoft co-founder Bill Gates.
During his 36-year tenure, Starbucks has grown from 11 stores to more than 28,000 stores across 77 countries.
The company made headlines in April when police arrested two African-American men while they were waiting for a friend at a Starbucks near Philadelphia.
Nearly immediately, speculation began that the 64-year-old entrepreneur would run as a Democratic Party candidate in 2020, likely in a presidential bid.
The company temporarily closed more than 8,000 U.S. stores after the arrest for racial bias training.
Starbucks declined to make Schultz or other Starbucks executives and board members available for comment.
In the meantime, he plans on working on his family foundation, and writing a book about the social responsibility companies have.
Starbucks shares closed up 0.28 per cent at United States dollars 57.07 in regular Monday trading on the Nasdaq, but were down 1 per cent at USD 56.50.
