Wal-Mart is closing 269 stores, more than half of them in the U.S. and another big chunk in its challenging Brazilian market. None of the stores are located in Maine or New Brunswick.

The stores being shuttered account for a fraction of the company's 11,000 stores worldwide and less than 1 percent of its global revenue. But 16,000 employees will be affected. The company has 22 stores in Maine and 12 in New Brunswick.

More than 95 percent of the stores set to be closed in the U.S. are within 10 miles of another Wal-Mart. The Bentonville, Arkansas, company said it is working to ensure that workers are placed in nearby locations.

The store closures will start at the end of the month.

The announcement comes three months after Wal-Mart Stores Inc. CEO Doug McMillon told investors that the world's largest retailer would review its fleet of stores with the goal of becoming more nimble in the face of increased competition from all fronts, including from online rival Amazon.com.

"Actively managing our portfolio of assets is essential to maintaining a healthy business," McMillon said in a statement. "Closing stores is never an easy decision. But it is necessary to keep the company strong and positioned for the future."

Wal-Mart operates 4,500 in the U.S. Its global workforce is 2.2 million, 1.4 million in the U.S. alone.

Of the closures announced Friday, 154 locations will be in the U.S., including the company's 102 smallest-format stores called Wal-Mart Express, which were opened as a test in 2011.

Also covered in the closures are 23 Neighborhood Markets, 12 supercenters, seven stores in Puerto Rico, six discount stores and four Sam's Clubs.

Wal-Mart will now focus in the U.S. on supercenters, Neighborhood Markets, the e-commerce business and pickup services for shoppers.

Wal-Mart said that it's still sticking to its plan announced last year to open 50 to 60 supercenters, 85 to 95 Neighborhood Markets and 7 to 10 Sam's Clubs in the U.S. during the fiscal year that begins Feb. 1. Outside the U.S., Wal-Mart plans to open 200 to 240 stores.
