Riverwoods, IL, April 19, 2023 - Discover Financial Services (NYSE: DFS) today reported net income of $1.0 billion or $3.58 per diluted share for the first quarter of 2023, as compared to a net income of $1.2 billion or $4.22 per diluted share for the first quarter of 2022.

“Our results for the first quarter of 2023 indicate a solid start to the year, with continued receivables growth and record deposit inflows, while credit is normalizing as expected. While there was stress across some segments of the banking system, our strong funding and capital generative business model enabled us to invest for growth while sustaining significant capital return to shareholders,” said Roger Hochschild, CEO and President of Discover. “We believe these factors create a compelling position for Discover in 2023 and beyond.”

Segment Results

Digital Banking

Digital Banking pretax income of $1.2 billion for the quarter was $498 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 $112.7 billion, up 21% year-over-year, and flat sequentially. Credit card loans ended the quarter at $89.8 billion, up 22% year-over-year. Personal loans increased $1.5 billion, or 21%, and private student loans increased $166 million, or 2%, year-over-year. The organic student loan portfolio, which excludes purchased loans, increased $313 million, or 3% from the prior year period.

Net interest income for the quarter increased $653 million, or 26% driven by higher average receivables and net interest margin expansion. Net interest margin was 11.34%, up 49 basis points versus the prior year. Card yield was 15.06%, up 247 basis points from the prior year primarily driven by higher market rates 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 230 basis points from the prior year period, primarily driven by higher funding costs.

Non-interest income increased $47 million, or 10%, from the prior year period, mainly driven by higher discount/interchange revenue and loan fee income partially offset by higher rewards cost driven by higher sales volumes.

The total net charge-off rate of 2.72% was 111 basis points higher versus the prior year period reflecting credit normalization across the portfolio. The credit card net charge-off rate was 3.10%, up 126 basis points from the prior year period and up 73 basis points from the prior quarter. The 30+ day delinquency rate for credit card loans was 2.76%, up 99 basis points year-over year and up 23 basis points from the prior quarter. The student loan net charge-off rate was 1.04%, up 35 basis points from the

prior year and down 29 basis points from the prior quarter. Personal loans net charge-off rate of 1.94% was up 82 basis points from the prior year and up 45 basis points from the prior quarter.

Provision for credit losses of $1.1 billion increased $948 million from the prior year driven by a $385 million reserve build in the current quarter compared to a $175 million reserve release in the prior year quarter and a $382 million increase in net-charge offs.

Total operating expenses were up $250 million year-over year, or 23%, driven primarily by higher expenses for employee compensation, professional fees, and marketing. The increase in employee compensation was driven by higher headcount. Professional fees increased due to investment in technology and consulting costs. Marketing increased primarily due to investments in consumer banking, card acquisition, and brand.

Payment Services

Payment Services pretax income of $47 million was up $148 million year-over-year. Higher revenue was driven by $162 million net losses on equity investments in the prior year quarter compared to $18 million net losses in the current year quarter.

Payment Services volume was $85.1 billion, up 10% year-over-year. PULSE dollar volume was up 9% primarily driven by increased debit transaction volume. Diners Club volume was up 28% year-over-year reflecting an improvement in global T&E and corporate spending. Network Partners volume decreased 1% from the prior year primarily reflecting lower transaction volume.

Share Repurchase

During the first quarter of 2023, the company repurchased approximately 11.3 million shares of common stock for $1.2 billion. Shares of common stock outstanding declined by 4.0% from the prior quarter.

The Board of Directors has approved a new $2.7 billion share repurchase program.

The company expects to make share repurchases from time to time subject to the company's capital plan, market conditions and other factors, including legal and regulatory restrictions and required approvals.
