An unnamed investor is in advanced talks for a possible sale of Dr. Martens, according to an unconfirmed report in The Wall Street Journal. The British owner of the brand, R. Griggs, had mandated Rothschild Trust Holding more than a year ago to sound out potential buyers. Some investment funds showed interest, but the price that they were offering was reportedly regarded as being too low in view of its strong growth. Company officials told us that its sales rose by 40 percent in the U.S. and on a global basis in 2012. The brand is now said to be generating annual sales of around $300 million, up from around $200 million for the financial year ended in March 2012.
