Permira has agreed to buy the parent company of the Dr. Martens brand for £300 million ($485.5 million). Barclays was the facility agent on the debt financing. Dr. Martens is a British footwear brand that dates back to 1960. Permira has experience backing global brands, with previous investments in Hugo Boss and Valentino. A number of firms were thought to have pursued a deal for Dr. Martens prior to Permira's agreement, including Warburg Pincus, Electra Partners and Pamplona Capital.
