Mitre 10 CEO John Hartmann has resigned to take up a job back in his native United States.
"We met John in 2009 and he joined our company shortly thereafter. His mandate as our CEO was to 'step change' the business and that has certainly been accomplished," chairman Martin Dippie said.
Last October Mitre 10 announced sales figures for the year ending 30 June of $858.4 million and a rebate to co-operative members of more than $45 million, sales figures that were up 6.5% on the previous year.
For the first six months of the new financial year Mitre 10 said its year-to-date sales figures are up 9.1% on the previous comparable period.
The company said "sustained growth over the last three years will see Mitre 10 punch through the $1 billion mark next year."
"It has been an honour and a privilege to work with the owners, operators and associates of Mitre 10. The level of passion and dedication across the business is apparent and the culture is one that is clearly focused on satisfying the customers' needs," Hartmann said.
Dippie added that Hartmann has the opportunity to take on the leadership of a company in his native USA and that he is working closely in support of the transition.
"A search is underway for John's successor and he will go with our best wishes."
