Exhibit 99.1 DISCOVER FINANCIAL SERVICES REPORTS FIRST QUARTER NET INCOME OF $666 MILLION OR $1.82 PER DILUTED SHARE Riverwoods, IL, April 26, 2018 - Discover Financial Services (NYSE: DFS) today reported net income of $666 million or $1.82 per diluted share for the first quarter of 2018, as compared to $564 million or $1.43 per diluted share for the first quarter of 2017. The company s return on equity for the first quarter of 2018 was 25%. First Quarter Highlights Total loans grew $6.9 billion ( 9% ) from the prior year to $82.7 billion. Credit card loans grew $5.8 billion ( 10% ) to $65.6 billion, on Discover card sales volume of $30.9 billion. Total net charge-off rate, excluding purchased credit-impaired ("PCI") loans, increased 48 basis points from the prior year to 3.17% and the total 30+ day delinquency rate excluding PCI loans increased 26 basis points from the prior year to 2.23%. Consumer deposits grew $4.2 billion ( 11% ) from the prior year to $41.3 billion. Payment Services transaction dollar volume was $56.1 billion, up 19% from the prior year. Our performance this quarter was characterized by robust loan and revenue growth reflecting the strength of the Discover franchise as we continued to invest in product and service enhancements," said David Nelms, chairman and CEO of Discover. I'm proud of our strong return on equity of 25%. In addition, this is the first full quarter reflecting the benefits of tax reform which, combined with share repurchases, led to a 27% year-over-year increase in earnings per share." Segment Results: Direct Banking Direct Banking pretax income of $811 million in the quarter declined by $13 million from the prior year driven by an increase in the provision for loan losses and higher operating expenses, partially offset by higher revenue. Total loans ended the quarter at $ 82.7 billion, up 9% compared to the prior year. Credit card loans ended the quarter at $65.6 billion, up 10% from the prior year. Personal loans increased $644 million ( 10% ) from the prior year. Private student loans increased $234 million ( 3% ) year-over-year, and grew $727 million ( 11% ), excluding purchased student loans. Net interest income increased $208 million ( 11% ) from the prior year, driven by loan growth and a higher net interest margin. Net interest margin was 10.23%, up 16 basis points from the prior year. Card yield was 12.85%, an increase of 20 basis points from the prior year as a result of increases in the prime rate, partially offset by a change in portfolio mix and higher interest charge-offs. Interest expense as a percent of total loans increased 23 basis points from the prior year, primarily as a result of higher market rates. Other income increased $19 million ( 5% ) from the prior year, driven by higher discount and interchange revenue. The delinquency rate for credit card loans 30+ days past due was 2.33%, up 27 basis points from the prior year and 5 basis points from the prior quarter. The credit card net charge-off rate for the first quarter was 3.32%, up 48 basis points from the prior year and 29 basis points from the prior quarter. The student loan net charge-off rate, excluding PCI loans, was 1.17%, up 34 basis points from the prior year. The personal loans net charge-off rate of 4.03% increased by 87 basis points from the prior year. Net charge-off rates were generally higher because of supply-driven credit normalization and the seasoning of loan growth from the last few years. Provision for loan losses of $751 million increased $157 million from the prior year due to higher net charge-offs and a higher reserve build. The reserve build for the first quarter of 2018 was $116 million, compared to a reserve build of $107 million in the first quarter of 2017.

Expenses increased $83 million from the prior year as a result of higher employee compensation and marketing expenses. Additionally, we expanded investments to build financial literacy, support diversity and inclusion, and strengthen the communities in which we operate. Employee compensation increased as a result of higher staffing levels and higher average salaries. Marketing expenses increased as a result of higher account acquisition costs and brand advertising. Payment Services Payment Services pretax income was $45 million in the quarter, up $1 million from the prior year, primarily driven by higher transaction processing and interchange revenue offset by a reserve release in the first quarter of 2017. Payment Services transaction dollar volume was $56.1 billion, up 19% versus the prior year. PULSE transaction dollar volume was up 20% year-over-year primarily driven by merchant and acquirer routing decisions. Diners Club volume increased 14% year-over-year driven by continued strength of newer franchise relationships. Network Partners volume increased by 24% from the prior year driven by AribaPay. Share Repurchases During the first quarter of 2018, the company repurchased approximately 7.5 million shares of common stock for $584 million. Shares of common stock outstanding declined by 1.8% from the prior quarter.

DISCOVER FINANCIAL SERVICES GLOSSARY OF FINANCIAL TERMS Book Value per share represents total equity divided by ending common shares outstanding Capital Returned to Common Stockholders represents common stock dividends declared plus treasury share repurchases minus common stock issued under employee benefit plans and stock based compensation Common Equity Tier 1 Capital Ratio (Basel III transition) represents common equity tier 1 capital divided by risk weighted assets calculated under Basel III rules subject to transition provisions Common Equity Tier 1 Capital Ratio (Basel III fully phased-in) represents fully phased-in common equity tier 1 capital divided by risk weighted assets under fully phased-in Basel III rules. The Common Equity Tier 1 Capital Ratio (Basel III fully phasedin) is calculated using Basel III fully phased-in common equity tier 1 capital, a non-gaap measure. The Company believes that the common equity tier 1 capital ratio based on fully phased-in Basel III rules is an important complement to the existing capital ratios and for comparability to other financial institutions. For the corresponding reconciliation of common equity tier 1 capital and risk weighted assets calculated under fully phased-in Basel III rules to common equity tier 1 capital and risk weighted assets calculated under Basel III transition rules see the Reconciliation of GAAP to non-gaap data schedule Delinquency Rate (Over 30 Days) represents loans delinquent over thirty days divided by ending loans (total or respective loans, as appropriate) Delinquency Rate (Over 90 Days) represents loans delinquent over ninety days divided by ending loans (total or respective loans, as appropriate) Discover Card Sales Volume represents Discover card activity related to net sales Discover Card Volume represents Discover card activity related to net sales, balance transfers, cash advances and other activity Discover Network Proprietary Volume represents gross proprietary sales volume on the Discover Network Earnings Per Share represents net income allocated to common stockholders divided by the weighted average common shares outstanding Effective Tax Rate represents tax expense divided by income before income taxes Gross Principal Charge-off Rate represents gross principal charge-off dollars (annualized) divided by average loans for the reporting period Interest Yield represents interest income on loan receivables (annualized) divided by average loans for the reporting period Liquidity Portfolio represents cash and cash equivalents (excluding cash-in-process) and other investments Net Income Allocated to Common Stockholders represents net income less (i) dividends and accretion of discount on shares of preferred stock and (ii) income allocated to participating securities Net Interest Margin represents net interest income (annualized) divided by average total loans for the period. Net Principal Charge-off Rate represents net principal charge-off dollars (annualized) divided by average loans for the reporting period Operating Efficiency represents total other expense divided by revenue net of interest expense Payout Ratio represents capital returned to common stockholders divided by net income allocated to common stockholders Pretax Return on Loan Receivables represents income before income taxes (annualized) divided by total average loans for the period Proprietary Network Volume represents gross proprietary sales volume on the Discover Network Ratio of Earnings to Fixed Charges is a year-to-date statistic and represents income before income tax expense and fixed charges divided by fixed charges for the reporting period. Fixed charges are the sum of interest expense, amortized premiums, discounts and capitalized expenses related to indebtedness and an estimate of interest within rental expense for the reporting period Regulatory Capital Ratios are regulatory measures used to evaluate capital adequacy. Under Basel III, for a Bank Holding Company to be considered "well-capitalized," total risk-based and tier 1 risk-based capital ratios of 10% and 6% respectively must be maintained. Under Basel III, to meet the regulatory minimum a Bank Holding Company must maintain total risk-based, tier 1 risk-based, tier 1 leverage, and common equity tier 1 ratios of 8%, 6%, 4%, and 4.5% respectively. As of January 1, 2015 regulatory capital ratios are calculated under Basel III rules subject to transition provisions. Total Risk Based Capital Ratio represents total capital divided by risk-weighted assets. Tier 1 Capital Ratio represents tier 1 capital divided by risk-weighted assets. Tier 1 Leverage Ratio represents tier 1 capital divided by average total assets. The Tier 1 Common Capital Ratio has been replaced by the Common Equity Tier 1 Ratio under Basel III Reserve Rate represents the allowance for loan losses divided by total loans Return on Equity represents net income (annualized) divided by average total equity for the reporting period Rewards Rate represents rewards cost divided by Discover Card sales volume Tangible Assets represents total assets less goodwill and intangibles Tangible Common Equity ("TCE"), a non-gaap financial measure, represents total common equity less goodwill and intangibles. The Company believes TCE is a more meaningful measure to investors of the net asset value of the Company. For corresponding reconciliation of TCE to a GAAP financial measure, see Reconciliation of GAAP to Non-GAAP data schedule Tangible Common Equity/Net Loans, a non-gaap measure, represents total common equity less goodwill and intangibles divided by total loans less the allowance for loan loss (period end) Tangible Common Equity per Share, a non-gaap measure, represents total common equity less goodwill and intangibles divided by ending common shares outstanding Tangible Common Equity/Tangible Assets, a non-gaap measure, represents total common equity less goodwill and intangibles divided by total assets less goodwill and intangibles Total Volume represents the transaction dollar volume from the PULSE network, Network Partners, Diners Club and proprietary Discover Network Undrawn Credit Facilities represents asset-backed conduit funding facilities and Federal Reserve discount window (excluding investments pledged to the Federal Reserve, which are included within the liquidity investment portfolio)
