Chris Armstrong to Retire from TD AMERITRADE in March 2009

TD AMERITRADE Holding Corporation (NASDAQ: AMTD) today announced that Chris Armstrong, head of the Company’s product strategy and marketing efforts, has decided to retire at the end of his employment contract, which expires in March 2009. This announcement provides the Company with ample time to search for his replacement and facilitate a smooth transition. Armstrong joined TD AMERITRADE following the close of the TD Waterhouse acquisition in January 2006 and helped integrate the two firms, bringing them together to support and advance the Company’s client segmentation strategy. He was also instrumental in the development and launch of TD AMERITRADE’s brand and advertising. He has served in a number of executive leadership positions, including the role of chief strategy officer and head of the Company’s client group, and is a member of the Company’s Senior Operating Committee. "Chris has been integral in the development of TD AMERITRADE and what we value as an organization,” said Joe Moglia, chief executive officer. "His marketing expertise helped us combine two vastly different businesses to create one successful Company with one vision and one promise for our clients and prospects. We wish Chris nothing but the best. He will be missed.” Armstrong will serve in his current role until his replacement is hired, at which point he will serve in an advisory position until the end of his contract. Internal and external opportunities will be explored in evaluating how to best fill this position.
