OMAHA, Neb., April 20, 2010 – TD AMERITRADE Holding Corporation (NASDAQ: AMTD) has released results for the second quarter of fiscal 2010. The combination of the Company’s financial strength and strong organic growth continues to position the firm well for the future.

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

	•		Net income of $163 million, or $0.27 per diluted share ($0.23 excluding the favorable resolution of certain income tax matters)(2)
	•		Record net new client assets of $10.2 billion, an increase of 59 percent, at an annualized growth rate of 13 percent of beginning client assets
	•		Average client trades per day of approximately 379,000, an increase of 17 percent
	•		Gross new accounts of approximately 187,000, a decrease of 4 percent
	•		Net revenues of $635 million, 47 percent of which were asset-based
	•		Operating income of $227 million, or 36 percent of net revenues
	•		Pre-tax income of $217 million, or 34 percent of net revenues
	•		EBITDA of $266 million, or 42 percent of net revenues(2)
	•		Liquid assets of $1.2 billion(2); cash and cash equivalents of $834 million
	•		Interest rate sensitive assets of $63.1 billion, up 15 percent(3)
	•		Record client assets of approximately $342 billion, an increase of 52 percent

“We continue to make great strides in attracting client assets and accounts in a difficult operating environment,” said Fred Tomczyk, president and chief executive officer. “We remain focused on executing our strategy, and our business model continues to perform well. Our organic growth has been outstanding. We are particularly proud of our record net new client asset growth and our record in total client assets. While short-term operating headwinds continue, we remain focused on our fundamentals and the key drivers of long-term earnings power and shareholder value.”

Company Updates Fiscal 2010 Outlook

The Company has adjusted its earnings per share outlook for fiscal 2010 to a new range of $0.90 to $1.10. More information can be found on the Company’s Outlook Statement, which is located on www.amtd.com.

“Throughout this difficult cycle, we have made a number of strategic decisions that have positioned us well for a rising interest rate environment. Our record net new asset growth has further enhanced our future earnings power,” said Bill Gerber, executive vice president and chief financial officer. “However, given the impact of lower intraday volatility, seasonal softening of client activity in the spring and summer months, and interest rates that we expect to remain low for at least the next six months, we have adjusted our outlook range for 2010.”
