Through 2027, the iPhone maker is discussing opening 15 new stores across the Asia-Pacific region, five locations in Europe and the Middle East, and four additional outlets in the US and Canada, according to people with knowledge of the deliberations. The company is also aiming for six revamped or relocated stores in Asia, nine in Europe and 13 in North America, said the people, who asked not to be identified because the matter is private. In total, the company is proposing 53 new, relocated or remodeled stores over the next four years.

Apple looks to bring fresh luster to its 22-year-old retail operation, which is one of the world’s most venerated chains but also has contended with pandemic woes, customer service problems and labor unrest in recent years. The idea is to build Apple’s brand in growth markets, such as India, while also giving consumers in the US and Europe a better experience.

The most notable new stores under discussion or in development include three sites in India, the company’s first outpost in Malaysia and an upgrade to Apple’s historic location in the Opera shopping area of Paris, according to the people. It’s also soon opening a store at the Battersea Power Station in London by its new local headquarters and is planning an additional location in Miami. And there’s a flagship store slated for the Jing’an Temple Plaza in Shanghai.

Some of the future locations and their timing remain either internal projections or proposals, meaning they could either be delayed or canceled altogether. Still, many of the stores are already in development, with Apple having agreed to leases with landowners. A spokesman for the Cupertino, California-based company declined to comment.
