Wal-Mart online chief Eduardo Castro-Wright to retire

New York City -- Wal-Mart Stores announced that Eduardo Castro-Wright, 56, vice chairman and CEO of the company’s global e-commerce and global sourcing businesses, will retire on July 1, 2012.

The company plans to name a replacement by the end of January, after which Castro-Wright will assist in the transition.

“Eduardo has made many contributions at Walmart, beginning in Mexico and continuing until today,” said Walmart CEO Mike Duke. “He has been a strong advocate for our customers and in every assignment has brought passion and commitment to the job. He has also built talented teams wherever he has led.”

Under Castro-Wright's leadership, Wal-Mart has significantly expanded its online business overseas. In May, the chain bought a minority stake in online company Yihaodian in China. It also has added online shopping for home delivery in a number of countries.

Castro-Wright also has helped Wal-Mart to develop its mobile and social commerce. In April, the chain bought social media company Kosmix.

The executive joined Walmart in 2001 as president and COO of Walmart Mexico and was promoted to president and CEO of that business in 2003. He also served as COO for a short period until being named president and CEO of Walmart U.S. in 2005.

He was promoted to vice chairman in 2008 and assumed his current responsibilities in August of last year. Since that time, Castro-Wright has overseen global sourcing and the expansion of the company.
