TD Ameritrade Continues to Deliver Double-Digit Client Asset Gathering

Net New Client Assets of $10 billion, 11% annualized growth rate
Average Trades Per Day of 372,000
December Quarter Earnings Per Share of $0.25

OMAHA, Neb., January 18, 2011 — TD Ameritrade Holding Corporation (NASDAQ: AMTD) has released results for the first quarter of fiscal 2011. The Company continues to execute on its organic growth strategy, again delivering double-digit annualized net new client asset growth.

The Company’s results for the quarter ended December 31, 2010 include the following (year-over-year comparisons): ⁽¹⁾

	•		Net income of $145 million, or $0.25 per diluted share
	•		Net new client assets of $9.7 billion, an increase of 11 percent, an annualized growth rate of 11 percent of beginning client assets
	•		Average client trades per day of approximately 372,000, a decrease of 2 percent
	•		Net revenues of $656 million, 51 percent of which were asset-based
	•		Operating income of $234 million, or 36 percent of net revenues
	•		Pre-tax income of $223 million, or 34 percent of net revenues
	•		EBITDA of $275 million, or 42 percent of net revenues(2)
	•		Record interest rate sensitive assets of $68 billion, up 13 percent(3)
	•		Record client assets of approximately $386 billion, an increase of 21 percent

“We continue to deliver strong organic growth and have proven the resilience of our strategy in a difficult, but slowly improving macroeconomic environment,” said Fred Tomczyk, president and chief executive officer. “We continue to execute well on our strategy, as evidenced by strong performances in both the retail and institutional sides of our business. With the market environment continuing to improve, we are seeing improvement in retail engagement and sentiment, and we feel good about how we are positioned going forward.”

“TD Ameritrade delivered a very strong performance this quarter, growing revenues despite continued interest rate pressure. Net new assets were at the top of our forecasted range and interest rate sensitive assets are at record levels, positioning us well for an improved rate environment,” said Bill Gerber, executive vice president and chief financial officer. “In addition, our strong cash position enabled us to effectively return 55 percent of our net income to shareholders through a share buyback and recently announced quarterly dividend.”

Stock Repurchases

During the first quarter of fiscal 2011, TD Ameritrade repurchased 3.2 million shares of its common stock at an average price of $15.94 per share, for approximately $50 million. The Company has 26.8 million shares remaining on its existing stock repurchase authorization.

Quarterly Dividend

The Company also announced that it has declared a $0.05 per share quarterly cash dividend, which is payable on February 15, 2011 to all holders of record of common stock as of February 1, 2011.
