Starbucks is planning to cut approximately 5 percent of its global corporate workforce, according to a memo sent by CEO Kevin Johnson on Tuesday.

About 350 employees in marketing, creative, product, technology and store development will be impacted, Johnson said in the memo obtained by CNBC.

Johnson said affected divisions will undergo "significant changes" as Starbucks narrows its priorities and aims to become a more nimble company. While the decisions were "incredibly difficult," he said they were made after "very careful consideration." Johnson said impacted roles were related to work that had been "eliminated" or "deprioritized."

The Wall Street Journal first reported the layoffs.

The news comes after Starbucks said in September it would cut corporate staff as it shuffles its organizational structure.

Starbucks has been plagued with lagging U.S. sales for several quarters. The coffee giant has scaled back on store growth and closed underperforming company-owned locations.
