STRONG ORGANIC GROWTH AT TD AMERITRADE CONTINUES
IN SECOND QUARTER

Quarterly earnings per share (EPS) of $0.23
Near-record trading levels and strong asset gathering
Best six months for new account growth in nine years

OMAHA, Neb., April 21, 2009 — TD AMERITRADE Holding Corporation (NASDAQ: AMTD) has released results for its second quarter of fiscal 2009, reporting strong business fundamentals and organic growth that continues in the face of a difficult market. Client engagement, both in terms of trading volume and new asset growth, combined with near-record new account openings led to a strong showing for the Company.

The Company’s results for the quarter ended Mar. 31, 2009 include the following (year-over-year comparisons): ⁽¹⁾

	•		Net income of $132 million, or $0.23 per diluted share
	•		Average client trades per day of approximately 325,000, an increase of 8 percent (2)
	•		Net new assets of approximately $6 billion, or an annualized growth rate of 11 percent on client assets at the beginning of the quarter
	•		Spread-based balances of approximately $27 billion, an increase of 5 percent (3)
	•		Fee-based balances of approximately $59 billion, a decrease of 17 percent
	•		Net revenues of $525 million, 48 percent of which were asset-based
	•		Pre-tax income of $224 million, or 43 percent of net revenues
	•		EBITDA of $258 million, or 49 percent of net revenues (4)
	•		Annualized return on average stockholders’ equity of 18 percent
	•		Client assets of approximately $225 billion, including $53 billion in client cash and money market funds

“While we still face some challenging headwinds, there are many things to be proud of this quarter,” said Fred Tomczyk, president and chief executive officer. “Our last six months speak for themselves — record trading volume, the best new account growth in nine years, and net new assets growing at an annualized rate of 10 percent of beginning client assets. We continue to manage for the other side of the cycle, taking advantage of our solid balance sheet, excellent liquidity and successful business model.”

“Our organic growth remains steady and strong,” said Bill Gerber, executive vice president and chief financial officer. “Despite a near-zero interest rate environment, our quarterly results remain solid. Looking forward, we will continue to prudently manage our business, backed by a strong, conservative balance sheet. With three credit rating agency upgrades to investment grade this quarter and our ongoing financial strength, we are in an excellent competitive position in this difficult environment.”

In the second quarter TD AMERITRADE repurchased approximately 36 million shares of its company stock at an average price of $11.88 per share. These transactions completed the Company’s stock buy-back programs. The Company has no immediate plans for additional share repurchases.
