Organic Growth Continues for TD Ameritrade

Net New Client Assets of $8 billion, 8% annualized growth rate
Trades Per Day of 370,000
June Quarter Earnings per Share of $0.27

OMAHA, Neb., July 19, 2011 — TD Ameritrade Holding Corporation (NASDAQ: AMTD) has released results for the third quarter of fiscal 2011. The Company continues to execute on its organic growth strategy, delivering strong net new client asset growth while returning 80 percent of its net income to shareholders through its stock repurchases and quarterly dividend.

The Company’s results for the quarter ended June 30, 2011 include the following (year-over-year comparisons):⁽¹⁾

	•		Net income of $157 million, or $0.27 per diluted share, including a $0.02 per share impact of technology-related asset write-offs
	•		Net new client assets of $7.9 billion, an annualized growth rate of 8 percent of beginning client assets
	•		Average client trades per day of approximately 370,000, a decrease of 11 percent
	•		Net revenues of $685 million, 54 percent of which were asset-based
	•		Operating income of $263 million, or 38 percent of net revenues
	•		Pre-tax income of $254 million, or 37 percent of net revenues
	•		EBITDA of $302 million, or 44 percent of net revenues(2)
	•		Record interest rate sensitive assets of $74 billion, an increase of 16 percent(3)
	•		Client assets of approximately $414 billion, an increase of 28 percent

“Despite the economic uncertainty and what looks to be a seasonally slow summer, we delivered solid growth in net new assets and asset-based revenues. Year-to-date, we have gathered $29.1 billion in net new assets, an annualized growth rate of 11 percent,” said Fred Tomczyk, president and chief executive officer. “Our strong financial position enabled us to buy back close to five million shares, or one percent of our outstanding common stock. And, when that is combined with our quarterly dividend, we returned 80 percent of our quarterly net income to shareholders. We remain focused on initiatives that will drive client engagement and fuel organic growth.”

“TD Ameritrade continues to deliver solid organic growth. Interest rate-sensitive balances reached a record high, including insured deposit account assets that have nearly doubled over the past two years and now exceed $50 billion,” said Bill Gerber, executive vice president and chief financial officer. “Despite the continued near-zero interest rate

environment, our net interest margin has remained relatively stable over the last four quarters. The strong growth in balances is resulting in solid asset-based revenues and positions us well for when interest rates begin to rise.”

Stock Repurchases

During the third quarter of fiscal 2011, TD Ameritrade repurchased 4.8 million shares of its common stock at an average price of $20.24 per share, for approximately $97 million. Year-to-date, the Company has used $191 million to repurchase 10 million shares at an average price of $19.05 per share. It has 20 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 Aug. 16, 2011 to all holders of record of common stock as of Aug. 2, 2011.
