Grant graduated from UCT in 1992 with a BSc degree in Electrical Engineering, after which he was employed by Anglo American Group as a management trainee. In 1993, after three and a half years with Anglo American, Grant moved to Monitor Group as a consultant.
A chance encounter with Massmart CEO, Mark Lamberti, in the reception at Massmart House paved Grant's route to a career in retail with Massmart in July 1998. He started his retail career in the role of Executive Assistant to the CEO, a position which he occupied for 2 years before being appointed Managing Director of Game Stores in October 2000.
This was followed 2 years later with his appointment as Group Commercial Executive in 2003. Grant was appointed to the Executive Committee in 2000, to the Board on 7 December 2004 and to the position of Deputy Chief Executive Officer on 1 July 2005. In July 2006 he became Chief Executive Officer Designate and was appointed CEO of Massmart Holdings on the 1st July, 2007, nine years after joining the group.
With 12 years experience working for Massmart, Grant has a solid understanding of the Group and has played an integral part in forming and leading its long-term strategy. This has included re-vitalising the Group's private label programme and leading Massmart’s entry into the retail food business.
Grant was appointed as Co-Chair of the Consumer Goods Council of South Africa in 2009. He has played a fundamental role in streamlining the management of the organization resulting in a more focused and established foundation to ramp up the future quality and quantity of service to its members and customers.
In September 2010 Massmart received a non-binding expression of interest from Walmart involving a cash offer of R148 per share for the issued share capital of the company. This resulted in a process during which Grant led discussions with Walmart which, in November 2010, resulted in a firm offer from Walmart to acquire 51 percent of Massmart at a cash price of R148.00 per Massmart ordinary share.
Grant subsequently provided the executive leadership necessary to navigate the acquisition through the competition approval process involving competition authorities in South Africa and four other African countries. The Massmart-Walmart merger was ultimately approved in all relevant jurisdictions.
The final phase of Grant's involvement in the merger has been devoted to integrating Massmart with Walmart in order to ensure the achievement of merger benefits and implementation of additional governance protocols associated with majority ownership by a listed United States based corporation.
