German sportswear giant Adidas said today it was mulling a sale of its long-struggling US subsidiary Reebok.

"Adidas has begun to assess strategic alternatives for Reebok," the company said in a statement, adding these "include both a potential sale of Reebok as well as Reebok remaining a part of the company". 

A decision will be announced on March 10, it added, when the group will present a new five-year strategy. 

Adidas acquired Boston-based Reebok in 2006 for €3.1 billion to take on US rival Nike. 

But the brand has struggled to grow under its German owner, frequently fuelling speculation of a sale. 

The brand is now worth only €803m, after several accounting write-downs, the last of which occurred in August after a 42% drop in sales in the second quarter to €228m. 

Germany's Manager Magazin reported in October that China's Anta Sports and North Face owner VF Corp were interested in acquiring Reebok. 

As far back as 2017, Adidas chief executive Kasper Rorsted had to face down shareholders calling for the sale of then loss-making Reebok. 

A turnaround plan initiated in 2016 reversed declining sales by 2019, before the pandemic forced store closures and halted the momentum. 

At the peak of the coronavirus restrictions in the second quarter, the Adidas group was forced to close around 70% of its stores worldwide. 

With sales of €1.75 billion in 2019, up 2% on the year before, Reebok accounted for just a fraction of the Adidas group's €23.6 billion in revenues last year.
