TD AMERITRADE’s Asset Gathering Success Continues with Double-Digit Growth Rate

Net New Assets of $9 billion, 10% annualized growth rate
Record Average Trades Per Day of 413,000
June Quarter Earnings Per Share of $0.30

OMAHA, Neb., July 20, 2010—TD AMERITRADE Holding Corporation (NASDAQ: AMTD) has released results for the third quarter of fiscal 2010. The Company continues to execute on its organic growth strategy, with record average trades per day and a double-digit annualized net new asset growth rate.

The Company’s results for the quarter ended June 30, 2010 include the following (year-over-year comparisons): ⁽¹⁾

• Net income of $179 million, or $0.30 per diluted share

• Net new client assets of $8.9 billion, an increase of 29 percent year-over-year, an annualized growth rate of 10 percent of beginning client assets

• Record average client trades per day of approximately 413,000, an increase of 6 percent

• Gross new accounts of approximately 175,000, virtually flat with the June 2009 quarter

• Record net revenues of $692 million, 47 percent of which were asset-based

• Operating income of $300 million, or 43 percent of net revenues

• Pre-tax income of $289 million, or 42 percent of net revenues

• EBITDA of $340 million, or 49 percent of net revenues⁽²⁾

• Liquid assets of $1.2 billion⁽²⁾; cash and cash equivalents of $716 million

• Record interest rate sensitive assets of $63.2 billion, up 13 percent⁽³⁾

• Client assets of approximately $324 billion, an increase of 22 percent

“With record trading and continued strong asset gathering results, we are quite happy with our performance this quarter. Year-to-date, our net new client assets gathered are a record $28 billion, up 32 percent year-over-year and growing at an annualized rate of over 12 percent,” said Fred Tomczyk, president and chief executive officer. “We remain focused on executing our growth strategy, maintaining strong business fundamentals and delivering value to our clients and shareholders.”

“Our continued focus on what we can control once again contributed to a strong quarter,” said Bill Gerber, executive vice president and chief financial officer. “Our sound financial position

and the successful execution of our strategy helped us increase asset-based revenues year-over-year by 24 percent. This, combined with record trading activity, led to a record $692 million in net revenues — a significant accomplishment given the ongoing low interest rate environment.”

Stock Buyback Completed

Beginning in the third quarter and through July 2, 2010, TD AMERITRADE repurchased 15 million shares of its common stock at an average price of $17.25 per share. These transactions completed the Company’s current stock buyback program.

“With our recent share repurchase program completed, and plans to make investments in the next wave of our growth, we continue to take a thoughtful, opportunistic approach to deploying capital,” Tomczyk continued. “That approach will not change as we continue to examine ways to use our strong cash position to enhance the client experience and build long-term value for our shareholders.”

Note: The term “GAAP” in the following explanation refers to generally accepted accounting principles in the United States.

(1)

EBITDA (earnings before interest, taxes, depreciation and amortization) is considered a non-GAAP financial measure as defined by SEC Regulation G. We consider EBITDA an important measure of our financial performance and of our ability to generate cash flows to service debt, fund capital expenditures and fund other corporate investing and financing activities. EBITDA is used as the denominator in the consolidated leverage ratio calculation for covenant purposes under our senior revolving credit facility. EBITDA eliminates the non-cash effect of tangible asset depreciation and amortization and intangible asset amortization. EBITDA should be considered in addition to, rather than as a substitute for, pre-tax income, net income and cash flows from operating activities.

(2)

Liquid assets is considered a non-GAAP financial measure as defined by SEC Regulation G. We define liquid assets as the sum of (a) corporate cash and cash equivalents, (b) corporate short-term investments, (c) regulatory net capital of (i) our clearing broker-dealer subsidiary in excess of 5% of aggregate debit items and (ii) our introducing broker-dealer subsidiaries in excess of 120% of the minimum dollar net capital requirement or in excess of 8 1/3% of aggregate indebtedness and (d) Tier 1 capital of our trust company in excess of the minimum dollar requirement. We include the excess capital of our broker-dealer and trust company subsidiaries in liquid assets, rather than simply including broker-dealer and trust cash and cash equivalents, because capital requirements may limit the amount of cash available for dividend from the broker-dealer and trust subsidiaries to the parent company. Excess capital, as defined under clauses (c) and (d) above, is generally available for dividend from the broker-dealer and trust subsidiaries to the parent company. We consider liquid assets an important measure of our liquidity and of our ability to fund corporate investing and financing activities. Liquid assets should be considered as a supplemental measure of liquidity, rather than as a substitute for cash and cash equivalents.
