PART II – RULES 12b-25 (b) and (c)

If the subject report could not be filed without unreasonable effort or expense and the registrant seeks relief pursuant to Rule 12b-25(b), the following should be completed. (Check box if appropriate)

PART III – NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report portion thereof, could not be filed within the prescribed time period.

Discover Financial Services (the “Company”) has determined that it is unable to file, without unreasonable effort or expense, its Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2024 (the “Form 10-Q”) within the prescribed time period for such report. As previously disclosed, as part of the review of the Company’s historical financial statements by the Staff of the U.S. Securities and Exchange Commission (the “Staff”) undertaken in connection with the Staff’s review of the Registration Statement on Form S-4 (the “Registration Statement”) filed by Capital One Financial Corporation (“Capital One”) in connection with the Company’s pending merger (the “Merger”) with Capital One (and the preliminary joint proxy statement/prospectus contained therein), the Staff indicated that it disagrees with certain aspects of the Company’s accounting approach for the card product misclassification matter. The Company requires additional time to file the Form 10-Q in order to address the Staff’s comments, which will likely involve implementation of the Reallocations (as defined in Part IV). The Company does not expect to file the Form 10-Q within the extension period of five calendar days permitted under Rule 12b-25 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Reallocations remain under review by the Company’s accounting staff and its independent registered public accounting firm and, once reported in the Form 10-Q, may differ from the description set forth in Part IV. The potential impact of the Reallocations on the Company’s previously filed historical financial statements is still being assessed and the Company and its independent registered accounting firm have not made any determinations as of the date of this filing with respect to whether the Reallocations will also involve any potential revisions or restatements of the Company’s previously filed historical financial statements. Cumulative historical earnings, capital and the aggregate amount of the counterparty restitution liability are not expected to be affected by the Reallocations.

The Company expects that Capital One will file a pre-effective amendment to the Registration Statement promptly following the Company’s filing of the Form 10-Q (and, to the extent applicable, the Company’s filing of any revisions or restatements of the Company’s previously filed historical financial statements) reflecting the Reallocations, and that as soon as practicable following the effectiveness of the Registration Statement and the mailing of the definitive joint proxy statement/prospectus contained therein to each company’s stockholders, each company will hold its respective special meeting of stockholders for purposes of obtaining the requisite stockholder approval of the Merger.

PART IV

OTHER INFORMATION

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The Company anticipates that, when filed, the Form 10-Q will likely reflect re-allocations (the “Reallocations”) to prior periods of approximately $600 million of the charge to other expense recorded in the Company’s Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2024 in respect of expected disbursements for counterparty restitution in connection with the card product misclassification matter. Because the Reallocations would reverse a charge to other expense recorded for the three months ended March 31, 2024, this would result in an increase in pre-tax income by the same amount in the three months ended March 31, 2024 and the nine months ended September 30, 2024.

As noted above, the Reallocations remain under review by the Company’s accounting staff and its independent registered public accounting firm and may differ once reported in the Form 10-Q. The potential impact of the Reallocations on the Company’s previously filed historical financial statements is still being assessed and the Company and its independent registered accounting firm have not made any determinations as of the date of this filing with respect to whether the Reallocations will also involve any potential revisions or restatements of the Company’s previously filed historical financial statements. The Company does not expect any revisions to its previously filed historical financial statements other than to properly reflect the Reallocations.

Cautionary Note Regarding Forward Looking Statements:

This Form 12b-25 contains “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements involve risks and uncertainties, and actual results could vary materially from these forward-looking statements. Factors that may cause future events or results to differ materially from management’s current expectations include the risk that the filing of the Form 10-Q and/or revisions or restatements to the Company’s previously filed historical financial statements and/or the declaration of effectiveness of the Registration Statement will take longer than expected or that the amount of the Reallocations will differ based on further review by the Company’s accounting staff and its independent registered accounting firm. The Company disclaims any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise, except as required by law.

Important Information About the Merger and Where to Find It

Capital One has filed the Registration Statement with the SEC to register the shares of Capital One’s common stock that will be issued to the Company’s stockholders in connection with the Merger. The Registration Statement includes a preliminary joint proxy statement of Capital One and the Company that also constitutes a preliminary prospectus of Capital One. The definitive joint proxy statement/prospectus will be sent to the stockholders of each of the Company and Capital One in connection with the Merger. INVESTORS AND SECURITY HOLDERS ARE URGED TO READ THE REGISTRATION STATEMENT AND JOINT PROXY STATEMENT/PROSPECTUS WHEN THEY BECOME AVAILABLE (AND ANY OTHER DOCUMENTS FILED WITH THE U.S. SECURITIES AND EXCHANGE COMMISSION (THE “SEC”) IN CONNECTION WITH THE MERGER OR INCORPORATED BY REFERENCE INTO THE JOINT PROXY STATEMENT/PROSPECTUS) BECAUSE SUCH DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION REGARDING THE MERGER AND RELATED MATTERS.

Information about the directors and executive officers of the Company and their ownership of the Company common stock can also be found in the Company’s definitive proxy statement in connection with its 2024 annual meeting of stockholders, as filed with the SEC on March 15, 2024, as supplemented by the Company’s proxy statement supplement, as filed with the SEC on April 2, 2024, and other documents subsequently filed by the Company with the SEC. Information about the directors and executive officers of Capital One and their ownership of Capital One common stock can also be found in Capital One’s definitive proxy statement in connection with its 2024 annual meeting of stockholders, as filed with the SEC on March 20, 2024, and other documents subsequently filed by Capital One with the SEC. Additional information regarding the interests of such participants will be included in the joint proxy statement/prospectus and other relevant documents regarding the Merger filed with the SEC when they become available.
