Record Average Client Trades per Day of 439,000
March Quarter Earnings per Share of $0.30

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

The Company’s results for the quarter ended March 31, 2011 include the following (year-over-year comparisons):⁽¹⁾

•

Net income of $172 million, or $0.30 per diluted share

•

Record net new client assets of $11.5 billion, an increase of 13 percent, an annualized growth rate of 12 percent of beginning client assets

•

Record average client trades per day of approximately 439,000, an increase of 16 percent

•

Record net revenues of $718 million, 49 percent of which were asset-based

•

Operating income of $283 million, or 39 percent of net revenues

•

Pre-tax income of $275 million, or 38 percent of net revenues

•

EBITDA of $324 million, or 45 percent of net revenues(2)

•

Record interest rate sensitive assets of $70 billion, an increase of 11 percent(3)

•

Record client assets of approximately $412 billion, an increase of 21 percent

“We continued our organic growth momentum by delivering another strong quarter, highlighted by record results in net new assets, trades per day, net revenues and total client assets,” said Fred Tomczyk, president and chief executive officer. “We remain focused on enhancing our client value proposition, which was recently recognized by Barron’s for its appeal to both long-term investors and active traders. And, we will continue to strategically invest to enhance our value proposition and build our long-term earnings power.”

“TD Ameritrade has delivered double-digit organic net new asset growth in eight of the last 10 quarters,” said Bill Gerber, executive vice president and chief financial officer. “That bodes well for our future earnings power, as we have also reached a turning point with net yields from our insured deposit account

increasing for the first time in over three years. Our strong cash position enabled us to continue our buy-back program, which together with our dividend payments, have resulted in our returning 48 percent of our net income to shareholders year-to-date.”

Stock Repurchases

During the second quarter of fiscal 2011, TD Ameritrade repurchased 2.0 million shares of its common stock at an average price of $21.03 per share, for approximately $43 million. The Company has 24.8 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 May 17, 2011 to all holders of record of common stock as of May 3, 2011.

Credit Rating Upgrade

On Feb. 25, 2011, Standard & Poor’s upgraded TD Ameritrade’s credit rating for the second time since 2008 to A- from BBB+. The Company also received its second ratings upgrade from Fitch Ratings to A- from BBB+ on April 15, 2011. Both ratings carry a “Stable” outlook.

“Our strong free cash flow, solid balance sheet and prospects for future earnings growth have led to two credit ratings upgrades in the midst of this continuing difficult economic environment,” Tomczyk continued.

Industry Recognition

TD Ameritrade was awarded an overall 4 ¹/2 out of 5 Stars and was named “Best for Options Traders” in Barron’s 2011 Online Broker Survey. TD Ameritrade also received the highest rating, 4 ¹/2 out of 5 Stars, in the “Best for Long-term Investing” category, sharing that rating with only one other broker. TD Ameritrade was evaluated versus 23 other online brokers in eight total categories, including trade experience, trading technology, usability, range of offerings, research amenities, portfolio analysis and reporting, customer service and costs.
