TD AMERITRADE’s Asset Gathering Success Continues with Double-Digit Growth Rate

Net New Assets of $9 billion, 10% annualized growth rate
Record Average Trades Per Day of 413,000
June Quarter Earnings Per Share of $0.30

OMAHA, Neb., July 20, 2010 — TD AMERITRADE Holding Corporation (NASDAQ: AMTD) has released results for the third quarter of fiscal 2010. The Company continues to execute on its organic growth strategy, with record average trades per day and a double-digit annualized net new asset growth rate.

The Company’s results for the quarter ended June 30, 2010 include the following (year-over-year comparisons): ⁽¹⁾

	•		Net income of $179 million, or $0.30 per diluted share
	•		Net new client assets of $8.9 billion, an increase of 29 percent year-over-year, an annualized growth rate of 10 percent of beginning client assets
	•		Record average client trades per day of approximately 413,000, an increase of 6 percent
	•		Gross new accounts of approximately 175,000, virtually flat with the June 2009 quarter
	•		Record net revenues of $692 million, 47 percent of which were asset-based
	•		Operating income of $300 million, or 43 percent of net revenues
	•		Pre-tax income of $289 million, or 42 percent of net revenues
	•		EBITDA of $340 million, or 49 percent of net revenues(2)
	•		Liquid assets of $1.2 billion(2); cash and cash equivalents of $716 million
	•		Record interest rate sensitive assets of $63.2 billion, up 13 percent(3)
	•		Client assets of approximately $324 billion, an increase of 22 percent

“With record trading and continued strong asset gathering results, we are quite happy with our performance this quarter. Year-to-date, our net new client assets gathered are a record $28 billion, up 32 percent year-over-year and growing at an annualized rate of over 12 percent,” said Fred Tomczyk, president and chief executive officer. “We remain focused on executing our growth strategy, maintaining strong business fundamentals and delivering value to our clients and shareholders.”

“Our continued focus on what we can control once again contributed to a strong quarter,” said Bill Gerber, executive vice president and chief financial officer. “Our sound financial position

and the successful execution of our strategy helped us increase asset-based revenues year-over-year by 24 percent. This, combined with record trading activity, led to a record $692 million in net revenues — a significant accomplishment given the ongoing low interest rate environment.”

Stock Buyback Completed

Beginning in the third quarter and through July 2, 2010, TD AMERITRADE repurchased 15 million shares of its common stock at an average price of $17.25 per share. These transactions completed the Company’s current stock buyback program.

“With our recent share repurchase program completed, and plans to make investments in the next wave of our growth, we continue to take a thoughtful, opportunistic approach to deploying capital,” Tomczyk continued. “That approach will not change as we continue to examine ways to use our strong cash position to enhance the client experience and build long-term value for our shareholders.”
