The buyout suffered from the effects of the 1987 stock market crash and after failing initially to raise high yield debt financing, the company was required to offer a portion of stock as an inducement to invest in the company's bonds. Various assets, such as the Chief Auto Parts chain, the ice division, and hundreds of store locations, were sold between 1987 and 1990 to relieve debt incurred during the buyout. This downsizing also resulted in numerous metropolitan areas losing 7-Eleven stores to rival convenience store operators. In October 1990, the heavily indebted Southland Corp. filed a pre-packaged Chapter 11 bankruptcy in order to transfer control of 70% of the company to Japanese affiliate Ito-Yokado. Southland exited bankruptcy in March 1991, after a cash infusion of $430 million from Ito-Yokado and Seven-Eleven Japan. These two Japanese entities now controlled 70% of the company, with the founding Thompson family retaining 5 percent. In 1999, Southland Corp. changed its name to 7-Eleven, Inc., citing the divestment of operations other than 7-Eleven. In 2005, Seven-Eleven Japan made a tender offer and 7-Eleven, Inc. became its wholly owned subsidiary. In 2007, Seven & i Holdings announced that it would be expanding its U.S. operations, with an additional 1,000 7-Eleven stores in the U.S. For the 2010 rankings, 7-Eleven climbed to the No. 3 spot in Entrepreneur magazine's 31st Annual Franchise 500, "the first and most comprehensive ranking in the world". This was the 17th year 7-Eleven was named in the top 10. Also in 2010, the first "green" 7-Eleven store opened in DeLand, Florida. The store features U.S. Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) elements. Also, the environmentally friendly design brings the store savings in energy costs. That same year, 7-Eleven went mobile with the launch of the Slurpee drink's iPhone and Android Application (App). The Slurpee drink app made it easy to find 7-Eleven stores and provides driving directions. The following year, 7-Eleven celebrated its 40,000th store opening and within two years of that milestone opened its 60,000th store. In 2020, 7-Eleven announced it would purchase Speedway for $21 billion. In 2021, 7-Eleven rolled out a $70 million ad campaign, their largest investment in advertising in years, doubling their market spending from the previous year. The commercials, directed by Harmony Korine, are to reflect the "evolution" of the chain's store format, drawing attention to, in part, the fact
