Reconciliation of Prior Periods in the Financial Supplement for reconciliation to previously reported results

Riverwoods, IL, July 19, 2023 - Discover Financial Services (NYSE: DFS) today reported net income of $901 million or $3.54 per diluted share for the second quarter of 2023, as compared to a net income of $1.1 billion or $3.93 per diluted share for the second quarter of 2022.

“This quarter again showed the strength of Discover’s business model, as revenue growth offset the impact of normalizing charge-offs, and our deposit base grew another 4%. We are also seeing positive early results from the relaunch of our cash back debit product, an important strategic milestone,” said Roger Hochschild, Discover’s CEO and President. “We are actively enhancing our governance and oversight structures and are making significant investments in our compliance management system. We remain deeply committed to achieving excellence in all these areas.”

Segment Results

Digital Banking

Digital Banking pretax income of $1.1 billion for the quarter was $322 million lower than the prior year period reflecting a higher provision for credit losses and higher operating expenses, partially offset by increased revenue net of interest expense.

Total loans ended the quarter at $117.9 billion, up 19% year-over-year, and up 5% sequentially. Credit card loans ended the quarter at $94.0 billion, up 19% year-over-year. Personal loans increased $2.0 billion, or 27%, and private student loans increased $167 million, or 2%, year-over-year. The organic student loan portfolio, which excludes purchased loans, increased $311 million, or 3% from the prior year period.

Net interest income for the quarter increased $567 million, or 22% driven by higher average receivables and net interest margin expansion. Net interest margin was 11.06%, up 12 basis points versus the prior year. Card yield was 15.14%, up 233 basis points from the prior year primarily driven by higher market rates and higher revolve rate, partially offset by higher interest charge-offs and a slightly higher mix of receivables at a promotional rate. Interest expense as a percent of total loans increased 260 basis points from the prior year period, primarily driven by higher funding costs.

Non-interest income increased $40 million, or 7%, from the prior year period, mainly driven by higher loan fee income and discount/interchange revenue, partially offset by higher rewards cost driven by a change in the 5% category from gas to restaurants.

The total net charge-off rate of 3.22% was 142 basis points higher versus the prior year period reflecting credit normalization across the portfolio. The credit card net charge-off rate was 3.68%, up 167 basis points from the prior year period and up 58 basis points from the prior quarter. The 30+ day delinquency rate for credit card loans was 2.86%, up 110 basis points year-over year and up 10 basis points from the prior quarter. The student loan net charge-off rate was 1.25%, up 17 basis points from the prior year and up 21 basis points from the prior quarter. Personal loans net charge-off rate of 2.28% was up 107 basis points from the prior year and up 34 basis points from the prior quarter.

Provision for credit losses of $1.3 billion increased $756 million from the prior year driven by a $263 million higher reserve build in the current quarter and a $495 million increase in net-charge offs.

Total operating expenses were up $173 million year-over year, or 15%, across most line items primarily driven by investment in compliance management systems. The increase in employee compensation was due to higher headcount. Professional fees increased due to higher technology and consulting costs, partially offset by a one-time adjustment related to collection fee expense. Marketing increased primarily due to investments in consumer banking products. Other expense increased due to legal reserve and remediation costs.

Payment Services

Payment Services pretax income of $70 million was up $50 million year-over-year. Higher revenue was driven by $42 million net losses on equity investments in the prior year quarter.

Payment Services volume was $89.3 billion, up 8% year-over-year. PULSE dollar volume was up 10% primarily driven by increased debit transaction volume. Diners Club volume was up 18% year-over-year reflecting an increase in corporate spending and an improvement in global T&E. Network Partners volume decreased 10% from the prior year primarily reflecting lower transaction volume.

Background on Card Product Misclassification

Beginning around mid-2007, Discover incorrectly classified certain credit card accounts into our highest merchant and merchant acquirer pricing tier. Incremental revenue resulting from this card product misclassification amounted to less than 1% of our cumulative discount and interchange revenue, gross, since that time, or less than two basis points as a percentage of sales over this timeframe. The misclassification affected pricing for certain merchants and merchant acquirers, but not for cardholders. Based on information available as of June 30, 2023, the Company determined that the revenue impact of the incorrect card product classification was not material to the consolidated financial statements of the Company for any of the impacted periods. Notwithstanding, for go-forward comparative purposes, the Company corrected the recognition of discount and interchange revenue as well as the related impacts to assets, liabilities and retained earnings in all prior periods presented. After adjusting for tax effects, the cumulative impact to beginning retained earnings as of April 1, 2023, was a decrease of $255 million, and the impact to net income for the quarter ended March 31, 2023, was a reduction of $8 million. As of June 30, 2023, the Company’s consolidated financial statements reflect a liability of $365 million within accrued expenses and other liabilities to provide refunds to merchants and merchant acquirers as a result of the card product misclassification.

Management is taking actions to correct the card product misclassification going forward and to prepare a program to compensate affected direct merchants and merchant acquirers. However, given differences in individual merchant agreements, changes in network terms, and availability of historical data, it is difficult to determine the final amount of potential refunds at this time. An investigation into this issue by an external law firm working at the direction of the Audit Committee of the Board of Directors is ongoing.

Discover is in discussions with its regulators regarding this matter and corporate governance and risk management. In addition, the Company received a proposed consent order from the FDIC in connection with consumer compliance. This proposed consent order does not include the card product classification matter. Additional supervisory actions could occur.

Share Repurchase

During the second quarter of 2023, the company repurchased approximately 6.8 million shares of common stock for $700 million. Shares of common stock outstanding declined by 2.6% from the prior quarter. The Company has decided to pause share repurchases while the internal review of compliance, risk management and corporate governance is pending.
