Second Quarter 2026 Financial Commentary

(All comparisons refer to the second quarter of 2025, except as noted)

Transportation Invoice and Dollar Volumes – Despite transportation invoice volumes of 8.7 million decreasing 1.9%, transportation dollar volumes of $10.1 billion increased 7.4%. The average dollars per invoice were $1,161 in the second quarter of 2026, compared to $1,115 in the first quarter of 2026 and $1,060 in the second quarter of 2025. Dollars per invoice increased due to an increase in overall freight rates, as well as the impact of fuel surcharges. The Company expects average dollars per invoice to continue increasing in future quarters due to the anticipated upward repricing of contract freight rates. A more detailed analysis of Cass Freight Index® changes can be found at www.cassinfo.com.

Facility Expense Invoice and Dollar Volumes – Facility expense invoice volumes of 4.0 million decreased 3.0%, and dollar volumes of $5.7 billion, increased 2.6%. The Company expects invoice volumes to increase on a quarter over prior year quarter basis beginning in the fourth quarter of 2026 as new clients are onboarded. Dollar volumes are expected to continue increasing compared to prior year quarters due to rising electricity and gas prices.

Processing Fees – Processing fees decreased $614,000, or 3.7%, due to lower transportation and facility invoice volumes.

Financial Fees – Financial fees, earned on a transactional level basis for invoice payment services when making customer payments, increased $790,000, or 7.8%. The increase in financial fees was primarily due to an increase in average payments in advance of funding of 19.4%. Rising freight rates, combined with higher demand for the Company’s early payment and other financial solutions, are expected to continue to drive an increase in payments in advance of funding and resulting financial fees in future quarters.

Net Interest Income – Net interest income increased $2.1 million, or 10.6%. The increase in net interest income was attributable to the net interest margin improving to 4.00% as compared to 3.78%, in addition to an increase in average interest-earning assets of $108.7 million, or 5.2%.

The Company’s net interest margin improvement was driven by increases in the average yield on loans and investment securities of 23 and 70 basis points, respectively, combined with a decrease in the average cost of total deposits of 20 basis points, partially offset by a decrease in the yield on short-term investments of 66 basis points. The increase in loan yield was driven by the continued maturity and subsequent re-pricing of fixed rate loans originated in the years 2021 and 2022 to current market interest rates. The increase in the investment securities yield was driven by the partial repositioning of the portfolio at the end of the second quarter of 2025 as well as purchases of investments at current market rates. The decline in the cost of total deposits and yield on short-term investments was driven by the reduction in the federal funds rate.

The Company expects continued expansion in its net interest margin in future quarters to the extent 3-5 year U.S. Treasury interest rates stay relatively consistent or increase as compared to current levels.

Provision for Credit Losses - The Company recorded a provision for credit losses of $531,000 during the second quarter of 2026 as compared to $25,000 in the second quarter of 2025. The provision for credit losses for the second quarter of 2026 was driven by loan growth as well as a specific reserve on a nonperforming commercial real estate loan.

Personnel Expenses - Personnel expenses decreased $667,000, or 2.4%, as compared to the second quarter of 2025. Salaries and commissions decreased $397,000, or 1.9%, as a result of the decrease in average full-time equivalent employees (“FTEs”) of 9.0% due to automation and the ongoing consolidation within our Facilities division, partially offset by merit increases. Share-based compensation and employee profit sharing increased $212,000 and $376,000, respectively, due to the improvement in net income from continuing operations. Other benefits decreased $858,000, or 18.6%, due to the decrease in FTEs in addition to lower health insurance claims and related expenses.

Salaries and commissions increased $973,000, or 5.0%, as compared to the first quarter of 2026 due to merit increases effective April 1, 2026, an increase in severance costs of $160,000 and one additional payroll day, partially offset by a 2.9% decrease in average FTEs.

Equipment Expense - Equipment expense increased $214,000 primarily due to an increase in depreciation and licensing and maintenance expense on software related to technology initiatives.

Bad Debt Recovery - The Company recorded a bad debt recovery of $1.8 million related to the second annual payment in a litigation settlement. There are three annual payments remaining of $1.25 million each, plus interest.

Other Expense - Other expense increased $828,000, or 12.1%. The increase is primarily due to higher business development costs and professional fees.

Loans - When compared to December 31, 2025, loans increased $41.8 million, or 3.9%. Other commercial and industrial loans have increased $38.0 million year-to-date due to organic growth and higher line utilization. The Company continues to expect loan growth of 6-8% for full year 2026.

Payments in Advance of Funding – Average payments in advance of funding increased $34.2 million, or 19.4%, primarily due to a 7.4% increase in transportation dollar volumes and a higher level of demand for the Company’s early payment and other financial solutions.

Deposits – Average deposits increased $66.1 million, or 6.6%. The Company experienced growth in average CassPay deposits of $43.4 million, or 18.0%, as compared to the second quarter of 2025.

Accounts and Drafts Payable - Average accounts and drafts payable increased $56.0 million, or 5.0%, as compared to the second quarter of 2025. The increase in these balances, which are non-interest bearing, is primarily reflective of the increase in transportation and facility dollar volumes of 7.4% and 2.6%, respectively.

Short-term Borrowings - The Company had outstanding borrowings of $80.0 million on its lines of credit at June 30, 2026 to provide funding for higher balances of payments in advance of funding and accounts and drafts receivable from customers at quarter end. Average short-term borrowings during the second quarter of 2026 were $10.0 million.

Shareholders’ Equity - Total shareholders’ equity increased $2.9 million as compared to March 31, 2026 as a result of net income of $10.6 million, partially offset by the repurchase of Company stock of $3.0 million and dividends of $4.1 million.

Dividend - On July 21, 2026, the Company’s Board of Directors approved a quarterly dividend of $0.32 per share with the dividend payable on September 14, 2026 to shareholders of record on September 4, 2026.

Repurchase of Common Stock - The Company repurchased 65,557 shares of common stock during the current quarter. The Company manages capital with an overall objective of maintaining a leverage ratio of approximately 10.00%. Future levels of repurchases will depend on market conditions, earnings, balance sheet growth and potential acquisition opportunities.

Asset Quality - Non-performing loans totaled $1.6 million at June 30, 2026, a decrease of $1.5 million as compared to March 31, 2026. The Company has two non-performing loan relationships remaining at June 30, 2026.

Outlook - The Company is optimistic regarding its revenue outlook as a result of i) the likelihood of sustained higher interest rates which would be expected to positively impact net interest margin; ii) the impact of higher contract freight rates and fuel surcharges which should lead to higher levels of accounts and drafts payable, net interest income and financial fees; iii) increased sales activity around early payment solutions within Transportation which generates financial fees: iv) organic loan growth opportunities; and v) increased sales activity around non-interest bearing CassPay deposits. In addition, the Company expects to be able to hold quarter over prior year quarter core expense growth to under 2% as a result of the continued focus on AI-enabled systems and other operational efficiency opportunities. While transaction growth in its Transportation and Facility businesses remains a challenge, the Company believes that recent technology investments into AI-enabled systems and a higher level of focus on business development positions the Company for better success in client growth in the mid-term.

The sale closed on June 30, 2025. The Company has applied discontinued operations accounting in accordance with FASB Accounting Standards Codification (“ASC”), Topic 205-20, “Presentation of Financial Statements – Discontinued Operations,” to the assets and liabilities sold related to the Company's TEM Business Unit as of and for the periods ended June 30, 2026, March 31, 2026, December 31, 2025, September 30, 2025, and June 30, 2025, as applicable. All financial information in this earnings release is reported on a continuing operations basis, unless otherwise noted.

About Non-GAAP Financial Measures

Certain of the financial measures and ratios the Company presents, including “adjusted net income from continuing operations,” and “adjusted diluted earnings per share from continuing operations,” are supplemental measures that are not required by, or are not presented in accordance with, U.S. generally accepted accounting principles (GAAP). The Company refers to these financial measures and ratios as “non-GAAP financial measures.” The Company considers the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding certain revenue and expense items that the Company believes are not indicative of its primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. The Company believes that management and investors benefit from referring to these non-GAAP financial measures in assessing the Company’s performance and when planning, forecasting, analyzing and comparing past, present and future periods.

These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and you should not rely on non-GAAP financial measures alone as measures of the Company’s

performance. The non-GAAP financial measures the Company presents may differ from non-GAAP financial measures used by the Company’s peers or other companies. The Company compensates for these differences by providing the equivalent GAAP measures whenever the Company presents the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing the Company’s performance. A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statement tables.

Forward Looking Information

All statements other than statements of historical fact included in this release, including without limitation the Company’s future prospects and performance, the business strategy and the plans and objectives of the Company's management for future operations, are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995.

Although the Company believes that the expectations reflected in the forward-looking statements are reasonable, the Company cannot guarantee future results, levels of activity, performance, or achievements.

Readers are cautioned not to place undue reliance on these forward-looking statements. Any forward-looking statement made by the Company in this release speaks only as of the date of this release. Unless required by law, the Company does not undertake to release publicly any revisions to these forward-looking statements to reflect future events or circumstances or to reflect the occurrence of unanticipated events.

www.cassinfo.com | ©2026 Cass Information Systems | The change in processing fees quarter to quarter is generally correlated to transportation and facility invoice volumes. Processing fees declined 3.7% as compared to 2Q2025 due to lower transportation and facility transaction volumes. Transportation invoice volumes of 8.7 million decreased 1.9% as compared to 2Q2025. Facility expense invoice volumes of 4.0 million decreased 3.0% as compared to 2Q2025. The Company expects Facility expense invoice volumes to increase on a quarter over prior year quarter basis beginning in 4Q2026 as new clients are onboarded. 8.84M 8.67M Q2'25 Q2'26 4.14M 4.02M Q2'25 Q2'26 $16.7M $16.1M Q2'25 Q2'26 Processing Fees and Transaction Volumes TRANSPORTATION INVOICE VOLUMES FACILITY INVOICE VOLUMES PROCESSING FEES 5

Dollars per invoice increased as compared to 2Q205 due to an increase in overall freight rates, as well as the impact of fuel surcharges. Facility expense dollar volumes totaled $5.7 billion, an increase of 2.6% as compared to 2Q2025. The increase in facility dollar volumes was primarily driven by rising electricity and gas prices. As a result of the increase in dollar volumes, average accounts and drafts payable increased $56.0 million, or 5.0%, as compared to 2Q2025, which positively impacts interest income as these funds are invested in cash and investment securities.

www.cassinfo.com | ©2026 Cass Information Systems | Financial Fees and Payments in Advance of Funding Financial fees increased $790,000, or 7.8%, from 2Q2025. The increase was due to an increase in average payments in advance of funding of 19.4%. Rising freight rates, combined with higher demand for the Company’s early payment and other financial solutions, are expected to continue to drive an increase in payments in advance of funding and resulting financial fees in future quarters. The percentage of transportation paid dollars advanced to freight carriers increased 138 basis points from 2Q2025. The increase was driven by a recent higher level of demand for the Company’s early payment solutions due to adoption strategies and market conditions. $176.2M $210.4M Q2'25 Q2'26 $10.2M $11.0M Q2'25 Q2'26 AVERAGE PAYMENTS IN ADVANCE OF FUNDINGFINANCIAL FEES 7 6.13% 7.51% Q2'25 Q2'26 PERCENTAGE OF TRANSPORTATION PAID DOLLARS ADVANCED

www.cassinfo.com | ©2026 Cass Information Systems | Net interest income increased $2.1 million, or 10.6%, from 2Q2025 driven by a higher net interest margin (NIM) and an increase in average interest-earning assets of $108.7 million, or 5.2%. The NIM improved 22 basis points from 2Q2025 to 4.00% largely driven by increases in the average yield on loans and investment securities of 23 and 70 basis points, respectively, combined with a decline in the average cost of total deposits of 20 basis points. The Company generally benefits from a higher interest rate environment due to a large percentage of its funding sources being non-interest bearing.

www.cassinfo.com | ©2026 Cass Information Systems | Loans increased $41.8 million, or 3.9%, as compared to December 31, 2025, driven by an increase in other C&I. The Company expects to achieve overall loan growth of 6-8% during full year 2026. The Company’s loan yield improved to 5.87% during 2Q2026 as compared to 5.64% during 2Q2025. The loan yield for 2Q2026 reflects continued maturity and subsequent re-pricing of fixed rate loans originated in 2021 and 2022 to current market rates.

www.cassinfo.com | ©2026 Cass Information Systems | Use of Non-GAAP Financial Measures Certain of the financial measures and ratios the Company presents, including “adjusted net income from continuing operations,” and “adjusted diluted earnings per share from continuing operations,” are supplemental measures that are not required by, or are not presented in accordance with, U.S. generally accepted accounting principles (GAAP). The Company refers to these financial measures and ratios as “non-GAAP financial measures.” The Company considers the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. The Company believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance by excluding certain revenue and expense items that the Company believes are not indicative of its primary business operating results or by presenting certain metrics on a fully taxable equivalent basis. The Company believes that management and investors benefit from referring to these non-GAAP financial measures in assessing the Company’s performance and when planning, forecasting, analyzing and comparing past, present and future periods. These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and you should not rely on non-GAAP financial measures alone as measures of the Company’s performance. The non-GAAP financial measures the Company presents may differ from non-GAAP financial measures used by the Company’s peers or other companies. The Company compensates for these differences by providing the equivalent GAAP measures whenever the Company presents the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing the Company’s performance. A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statement tables. 16
