Peter Roberts named Chief Strategy Officer and Lauralee Martin appointed Chief Executive Officer, Americas

CHICAGO, November 27, 2012 – Jones Lang LaSalle (NYSE: JLL) announced today two leadership changes that will position the firm for further growth in the coming years. Peter Roberts, currently Chief Executive Officer, Americas, will become Chief Strategy Officer. Lauralee Martin, currently Chief Operating and Financial Officer, will succeed Roberts as CEO, Americas. The changes will be effective January 1, 2013.

Roberts has made significant contributions to Jones Lang LaSalle, both in the Americas region and for the firm globally. During his 10-year tenure as CEO of the Americas, annual revenues in the region have grown six-fold through organic growth and transformational mergers. He also has been a member of the firm’s Global Executive Committee, which guides the firm’s global strategy.

“Peter has played a leading role in making Jones Lang LaSalle the premier commercial real estate brand in the Americas,” said Colin Dyer, Chief Executive Officer of Jones Lang LaSalle. “In the newly created role of Chief Strategy Officer, he will combine his real estate expertise, client-first perspective and critical thinking to help implement our growth strategy for the future.”

Martin joined Jones Lang LaSalle in 2002 as Chief Financial Officer and was appointed to the additional position of Chief Operating Officer in 2005. Under her leadership, the firm has maintained an investment grade balance sheet. She built the firm’s industry-leading Energy and Sustainability Services business, helped structure acquisitions across its global platform, and contributed to productivity growth and client service through the development of a globally unified technology platform.

Martin and Roberts will work together to ensure a seamless transition while a search is conducted for the Chief Financial Officer role. Until a new CFO is appointed, Martin will retain responsibility for the function.
