Exhibit 99.3

SCHWAB UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

On November 24, 2019, The Charles Schwab Corporation (“Schwab”) entered into a merger agreement with TD Ameritrade Holding Corporation (“TD Ameritrade”) and Americano Acquisition Corp. (“Merger Sub”), a wholly owned subsidiary of Schwab. Upon the terms and subject to the conditions of the merger agreement, Merger Sub will merge with and into TD Ameritrade pursuant to the merger, with TD Ameritrade surviving as a wholly owned subsidiary of Schwab. The merger agreement was unanimously approved by the Schwab board of directors and the TD Ameritrade board of directors, acting upon the unanimous recommendation of its strategic development committee.

If the merger is completed, TD Ameritrade stockholders immediately prior to the effective time of the merger will receive, in exchange for each share of TD Ameritrade common stock owned immediately prior to the merger, 1.0837 shares of Schwab common stock. Fractional shares of Schwab common stock will not be issued to TD Ameritrade stockholders, who will receive cash in lieu of fractional shares following the closing of the merger. The cash payment for the fractional shares is not anticipated to be material.

The following unaudited Pro Forma Condensed Combined Balance Sheet (“Pro Forma Balance Sheet”) and unaudited Pro Forma Condensed Combined Statement of Income (“Pro Forma Statement of Income”, and together with the Pro Forma Balance Sheet, the “Pro Forma Financial Statements” or the “Statements”) are based on the separate historical consolidated financial statements of Schwab and TD Ameritrade after giving effect to the acquisition of TD Ameritrade by Schwab and the exchange of Schwab’s common stock for TD Ameritrade’s outstanding common stock in connection therewith, and the assumptions and adjustments described in the accompanying notes to the Pro Forma Financial Statements. The Pro Forma Balance Sheet as of December 31, 2019 is presented as if the merger occurred on December 31, 2019. The Pro Forma Statement of Income for the year ended December 31, 2019 is presented as if the merger occurred on January 1, 2019. The historical financial information has been adjusted to reflect factually supportable items that are directly attributable to the merger and, with respect to the Pro Forma Statement of Income only, expected to have a continuing impact on the combined results of operations.

Due to the timing of the merger, the estimates of fair value are preliminary and are dependent upon certain valuations that have not progressed to a stage where there is sufficient information to make a definitive valuation. The unaudited pro forma adjustments, including the allocations of the Purchase Price, have been made solely for the purpose of providing unaudited pro forma condensed combined financial information. The determination of estimated fair values requires management to make significant estimates and assumptions, which are described in the accompanying notes to the Pro Forma Financial Statements, based on currently available information. Schwab believes that the information available provides a reasonable basis to estimate the fair values of assets acquired and liabilities assumed; however, these preliminary estimates may be adjusted upon the availability of new information regarding facts and circumstances as they exist at the date of the merger. Therefore, there can be no assurance that such changes will not be material. A final determination of the Purchase Price and fair values of TD Ameritrade’s assets and liabilities will be based on the actual tangible and intangible assets and liabilities of TD Ameritrade that exist as of the date of the merger.

The Statements are provided for illustrative purposes only and are not necessarily indicative of the combined financial position or results of operations that might have been achieved had the merger been completed as of the dates indicated, nor are they meant to be indicative of any anticipated combined financial position or future results of operations that the combined company will experience after the merger. The Pro Forma Financial Statements also do not reflect potential revenue enhancements (or the necessary costs to achieve such benefits), cost savings, or operating synergies that Schwab expects to realize after the merger. In addition, the Pro Forma Statement of Income does not reflect restructuring or exit costs, which may be incurred by Schwab in connection with the merger.

The preparation of the Pro Forma Financial Statements and related adjustments required management to make certain assumptions and estimates. The Statements should be read together with:

NOTES TO UNAUDITED PRO FORMA FINANCIAL STATEMENTS

1. Basis of Pro Forma Presentation

The Pro Forma Financial Statements were prepared in accordance with Article 11 of SEC Regulation S-X. Schwab’s fiscal year end is December 31 and TD Ameritrade’s fiscal year end is September 30. The Pro Forma Balance Sheet as of December 31, 2019 combines Schwab’s historical audited consolidated balance sheet as of December 31, 2019 and TD Ameritrade’s historical unaudited condensed consolidated balance sheet as of December 31, 2019, giving effect to the merger as if it was completed on December 31, 2019.

The Pro Forma Statement of Income combines the Schwab historical audited consolidated statement of income for the year ended December 31, 2019 and the TD Ameritrade historical consolidated statement of income for the trailing twelve months ended December 31, 2019. For the purpose of preparing the Pro Forma Statement of Income for the year ended December 31, 2019, the “TD Ameritrade Historical — After Reclassification” column, which represents the trailing twelve month period ended December 31, 2019, was derived by subtracting TD Ameritrade’s historical unaudited condensed consolidated statement of income for the three months ended December 31, 2018 from its historical audited consolidated statement of income for the year ended September 30, 2019, and by adding TD Ameritrade’s historical unaudited condensed consolidated statement of income for the three months ended December 31, 2019.

Certain financial information of TD Ameritrade, as presented in its historical consolidated financial statements, has been reclassified to conform to the historical presentation in Schwab’s consolidated financial statements for the purpose of preparing the Pro Forma Financial Statements. Certain financial information of Schwab, as presented in its historical consolidated financial statements, has been reclassified for the purpose of preparing the Pro Forma Financial Statements to reflect planned changes in Schwab’s presentation subsequent to the merger. Refer to Note 3 of the Statements for explanations of these reclassifications.

The merger will be accounted for under the acquisition method of accounting in accordance with Accounting Standards Codification (ASC) Topic 805, Business Combinations (“ASC 805”), with Schwab as the acquirer for accounting purposes. Under ASC 805, the total Purchase Price was calculated as described in Note 4 of the Statements. The assets acquired and liabilities assumed from TD Ameritrade have been measured at their estimated fair values on the assumed acquisition date, except for certain exceptions to the recognition principle of acquisition accounting, such as leases, share-based payments, and income taxes. The excess of the Purchase Price over the assets acquired and liabilities assumed is allocated to goodwill. Subsequent to the completion of the merger, Schwab and TD Ameritrade will finalize an integration plan, which may affect how the assets acquired, including intangible assets, will be utilized by the combined company.

The income tax effects of pro forma adjustments are calculated based on a blended U.S. federal and state statutory tax rate of 24.32%.

Upon consummation of the merger and the completion of a valuation, the Purchase Price as well as the estimated fair values of the assets and liabilities will be updated and finalized as soon as practicable, but not later than one year from the merger date.

2. Accounting Policies

As part of preparing the Pro Forma Financial Statements, Schwab conducted a preliminary review of the accounting policies of TD Ameritrade, but did not note any material differences in accounting policies that would require pro forma adjustments to conform to Schwab’s accounting policies. Further, Schwab considered the difference in TD Ameritrade’s fiscal year end and its impact on the adoption of new accounting standards and noted no material impacts.

5

Upon consummation of the merger, a more comprehensive review of the accounting policies of TD Ameritrade will be performed, which may identify other differences among the accounting policies of Schwab and TD Ameritrade that, when conformed, could have a material impact on the Pro Forma Financial Statements.

The accounting policies used in the preparation of the Statements are those set out in Schwab’s audited consolidated financial statements as of and for the year ended December 31, 2019.

4. Calculation of Estimated Purchase Price and Preliminary Purchase Price Allocation

The calculation of the Purchase Price and allocation to assets acquired and liabilities assumed is preliminary because the merger has not yet been completed. The preliminary allocation to assets and liabilities is based on estimates, assumptions, valuations, and other studies which have not progressed to a stage where there is sufficient information to make a definitive calculation. Accordingly, the Purchase Price allocation reflected in the unaudited pro forma adjustments will remain preliminary until Schwab management determines the final Purchase Price and the fair values of assets acquired and liabilities assumed. The final determination of the Purchase Price and related allocation is anticipated to be completed as soon as practicable after the completion of the merger and will be based on the value of Schwab’s stock price at the closing of the merger.

The fair value of the Purchase Price to be transferred upon completion of the merger will include the fair value of Schwab’s common stock to be issued to TD Ameritrade stockholders pursuant to the merger agreement and the fair value of the replaced TD Ameritrade equity awards attributable to pre-combination services. The preliminary Purchase Price is calculated as follows:

Purchase Price Sensitivity

The final Purchase Price could significantly differ from the amounts presented in the unaudited pro forma condensed combined financial information due to movements in the price of Schwab’s common stock prior to the closing date of the merger. A sensitivity analysis related to the fluctuation in the price of Schwab’s common stock was performed to assess the impact a hypothetical change of 10% on the trading price of Schwab common stock on the NYSE on March 3, 2020 would have on the estimated Purchase Price and goodwill as of the closing date of the merger.

Preliminary fair value estimate of assets acquired and liabilities assumed

Under the acquisition method of accounting, the identifiable assets acquired and liabilities assumed of TD Ameritrade are recorded at the merger date fair values, except for certain balances related to leases, share-based payments, and income taxes for which an exception from fair value accounting applies. Schwab has prepared preliminary estimates of the fair value of identified intangible assets, tangible assets and certain financial assets and financial liabilities as described in Note 5. Assumed long-term debt, which consists of publicly traded senior notes, is measured at its estimated fair value. The pro forma adjustments are preliminary and based on estimates of the fair value and useful lives of the assets acquired and liabilities assumed and have been prepared to illustrate the estimated effect of the merger. The allocation is dependent upon certain valuation and other studies that have not yet been finalized. Accordingly, the pro forma Purchase Price allocation is subject to further adjustment as additional information becomes available and as additional analyses and final valuations are completed, and such differences could be material.

13

The following table sets forth a preliminary allocation of the Purchase Price to the identifiable tangible and intangible assets acquired and liabilities assumed of TD Ameritrade using TD Ameritrade’s unaudited condensed consolidated balance sheet (after reclassification) as of December 31, 2019, with the excess recorded to goodwill:

Goodwill represents the excess of the preliminary Purchase Price over the preliminary fair value of the underlying tangible and intangible assets acquired and liabilities assumed. Among the factors that contributed to a Purchase Price in excess of the fair value of the identifiable tangible and intangible assets acquired and liabilities assumed are the skill sets, operations, and synergies that can be leveraged to enable the combined company to build a stronger enterprise. In accordance with ASC Topic 350, Intangibles – Goodwill and Other, goodwill will not be amortized, but instead will be tested for impairment at least annually and whenever events or circumstances have occurred that may indicate a possible impairment. In the event management determines that the value of goodwill has become impaired, the combined company will incur a charge to earnings for the amount of the impairment during the period in which the determination is made. Goodwill recorded in the merger is not expected to be deductible for tax purposes.

The pro forma historical net assets adjustments as shown above are further described below in Notes 5 and 6.

Equipment, office facilities, and property — net and Acquired intangible assets — net

The estimated fair values of personal property, real property, and construction in progress were determined using a sales comparison and cost approach, including consideration of functional and economic obsolescence. Schwab estimated the weighted-average useful lives of the assets based on the current condition and expected future use of the assets.

The preliminary fair values of customer relationships, existing technology, and trade names were determined based on the provisions of ASC 805, which defines fair value in accordance with ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Intangible assets were identified that met either the separability criterion or the contractual-legal criterion described in ASC 805. The fair value of the customer relationships was estimated using a multi-period excess earnings approach and the fair value of existing technology and trade names was estimated using a relief from royalty approach.

The following table summarizes the major classes of tangible and intangible assets and their respective weighted-average estimated useful lives:

5. Pro Forma Balance Sheet Adjustments

The following unaudited pro forma adjustments result from accounting for the merger, including the determination of the fair value of the assets, liabilities, and commitments which Schwab, as the acquirer for accounting purposes, will acquire and assume from TD Ameritrade.

Adjustments included in the “Pro Forma Adjustments” column in the accompanying Pro Forma Balance Sheet as of December 31, 2019 are as follows:

16

The total costs and expenses relating to the merger are estimated to be $153 million, pre-tax, of which $37 million are included in the historical financial information for Schwab and TD Ameritrade for the year ended December 31, 2019 and an additional $116 million are expected to be incurred at close. Our estimate includes costs and expenses related to various professional fees and other costs associated with the merger such as advisory, legal, accounting, tax, and printing fees. The estimate involves a degree of judgment which Schwab management believes to be reasonable as of the date of this Current Report on Form 8-K. There can be no assurance that these estimates will not change, even materially, as the transaction progresses to the closing date of the merger. These transaction related costs are one-time in nature and are not expected to have a continuing impact on Schwab’s ongoing results of operations. Thus, while they are accrued on the Pro Forma Balance Sheet, they are not reflected in the Pro Forma Statement of Income.

6. Pro Forma Statement of Income Adjustments

Adjustments included in the “Pro Forma Adjustments” column in the accompanying Pro Forma Statement of Income are as follows:

7. Earnings Per Share

The preliminary pro forma basic earnings per common share is computed by dividing combined pro forma net income attributable to Schwab common stock by pro forma weighted-average common shares outstanding. The pro forma weighted-average common shares outstanding is based on Schwab’s historical weighted-average common shares adjusted for the issuance of 586 million shares of common stock to the TD Ameritrade stockholders (refer to Note 4), assuming the merger occurred on January 1, 2019. Of the 586 million shares of common stock, 518 million shares were voting common stock and 68 million shares were nonvoting common stock. The preliminary pro forma diluted earnings per share calculation is similar to the computation of the pro forma basic earnings per share except that the denominator is increased to include the number of additional common shares that would have been outstanding if dilutive potential common shares had been issued. Dilutive potential common shares include, if dilutive, the effect of outstanding stock options and non-vested restricted stock units of Schwab, as well as the common shares that have dilutive effect resulting from the replacement of TD Ameritrade’s employee equity awards, assuming the merger occurred on January 1, 2019. As the participation rights, including dividend and liquidation rights, are identical between the voting common stock and nonvoting common stock classes, basic and diluted earnings per share are the same for each class. Accordingly, the basic and diluted earnings per common share were not separately disclosed for each class in the Pro Forma Statement of Income.
