PURCHASE, N.Y. — PepsiCo, Inc. has unveiled a number of leadership appointments designed to support the company’s global business priorities and growth strategies.

Hugh Johnston, executive vice-president, chief financial officer and vice-chairman

Hugh Johnston, executive vice-president and chief financial officer, has been named vice-chairman. Mr. Johnston will continue to serve as c.f.o., a position he has held since 2010, as well as oversee the Quaker Foods North America business and PepsiCo’s global e-commerce organization. He also will add responsibility for the company’s global business and information solutions function, which provides information technology systems and solutions across PepsiCo.

The move follows the company’s appointment of Mehmood Khan, executive vice-president and chief scientific officer, to vice-chairman earlier this year. In his role, Mr. Khan is focused on leading PepsiCo’s global sustainability agenda and identifying new ways to embed sustainable business practices across all facets of the company's business. He continues to lead PepsiCo’s global research and development organization.

Other executive changes included:

• Eugene Willemsen, currently president, PepsiCo Lipton, has been named executive vice-president, global categories and franchise management.

PepsiCo said that Mr. Narasimhan’s appointment accompanies a realignment of certain reportable segments of the company’s business that will begin in the third quarter of 2015.

PepsiCo’s Sub-Saharan Africa business, which is currently part of the Asia, Middle East and Africa division, will move to the Europe segment, which is renamed Europe Sub-Saharan Africa (ESSA).
