MFS COMPLETES MOVE OF CORPORATE HEADQUARTERS

Move Caps Active Year of Rebranding and New Offices Opening around the World

BOSTON (December 20, 2012) – MFS® completed the move of its corporate headquarters to 111 Huntington Avenue this week, concluding an active year for the Boston-based global asset manager. Earlier this year, MFS relaunched its corporate brand identity, launched its first-ever global advertising campaign and opened new offices in São Paulo, Hong Kong and Sydney.

"Our move caps off a dynamic year, full of new beginnings, strong performance and a growing global presence. We are looking forward to the capabilities, convenience and wonderful panoramic views offered by 111 Huntington," said Robert Manning, Chairman and CEO of MFS. "We believe our employees and clients alike will appreciate this new, modern office facility that reflects MFS' position as a leading active global asset manager."

MFS' Boston-based employees moved in stages over the three prior weekends. Waiting for them were height-adjustable desks, enhanced audio visual conference and presentation facilities, and office space with ample natural light. MFS constructed its office space with the goal of achieving Leadership in Energy and Environmental Design (LEED) Gold certification, to meet the strictest standards of environmentally friendly office space.

"We have created an advanced office environment that provides our employees with comfort and flexibility and allows them to communicate with their colleagues efficiently on a global basis — a critical need for a global asset manager," added Michael Roberge, President and Chief Investment Officer. "Furthermore, the design respects and acknowledges the importance MFS places on conservation and environmental impact."

Earlier this year, MFS established research offices in São Paulo and Hong Kong as well as relocated and expanded its Singapore office. The firm now has nine investment research offices located in major financial centers around the globe. In July, MFS opened its first independent sales and service office in Sydney, Australia, bringing to 20 the number of client-facing offices it operates worldwide.
