Buyout firm Permira is working with Goldman Sachs Group and Robert W. Baird as it explores options for iconic British bootmaker Dr. Martens, sources have said.

According to the sources, Permira is in the early stages of considering options including a sale or IPO of the business, with a 2020 exit targeted. Any deal would add to the £24.6 billion in sales of U.K. consumer companies announced this year, according to data compiled by Bloomberg. Permira bought Dr. Martens in 2014 for £304 million ($432 million). It has since increased the company’s global presence, opening 24 stores last year, and expanded its e-commerce offering.

Dr. Martens reported more than £80 million ($102 million) of earnings before interest, taxes, depreciation and amortisation for the financial year through March 2019. Representatives for Permira and Goldman Sachs have declined to comment.
