COMMERCE BANCSHARES, INC. REPORTS
SECOND QUARTER EARNINGS PER SHARE OF $1.10

Commerce Bancshares, Inc. announced earnings of $1.10 per share for the three months ended June 30, 2026, compared to $1.09 per share in the same quarter last year and $.96 per share in the first quarter of 2026. Net income for the second quarter of 2026 amounted to $159.8 million, compared to $152.5 million in the second quarter of 2025 and $141.6 million in the prior quarter.

For the six months ended June 30, 2026, earnings per share totaled $2.06 compared to $2.02 for the first six months of 2025. Net income amounted to $301.4 million for the six months ended June 30, 2026, compared to $284.1 million in the comparable period last year. For the year to date, the return on average assets was 1.73%, and the return on average equity was 13.96%.

In making this announcement, John Kemper, Chief Executive Officer, said, “Commerce delivered a strong quarter, with expanding net interest margin, solid loan growth, lower funding costs and excellent credit quality. These results drove a return on average assets of 1.84% and reflect the strength of our business model, our diversified revenue streams and our team’s continued focus on long-standing customer relationships.”

Mr. Kemper continued, “Revenue growth was broad-based during the quarter. Net interest income increased as margin expanded to 3.77%, and fee revenue grew $8.0 million this quarter, supported by continued strength in trust, bank card and deposit-related businesses. We believe this balanced revenue mix remains a key differentiator for Commerce and supports consistent performance across economic cycles.”

“We remained focused on disciplined capital management. During the quarter, we repurchased approximately 2.1 million shares of common stock for $110 million while maintaining a strong capital position. This gives us flexibility to invest in growth, support our customers and continue returning capital to shareholders.”

“We also completed the repositioning of a portion of our available for sale securities portfolio, including the sale of our Treasury inflation-protected securities portfolio. This repositioning increases the portfolio’s overall yield, improves the consistency of future net interest income, and supports a more durable net interest margin over time. We believe these portfolio changes strengthen Commerce’s long-term earnings profile and position us to deliver sustained shareholder value.”

Second Quarter 2026 Financial Highlights:

Net interest income was $315.1 million, a $15.2 million increase over the prior quarter. The net yield on interest earning assets increased 18 basis points to 3.77%.

Management Discussion of Second Quarter Results
June 30, 2026
For the quarter ended June 30, 2026, net income amounted to $159.8 million, compared to $141.6 million in the previous quarter and $152.5 million in the same quarter last year. The increase in net income over the previous quarter was primarily the result of higher net interest income, non-interest income, and a decrease in the provision for credit losses, partly offset by higher non-interest expense. The net yield on interest earning assets increased 18 basis points over the previous quarter to 3.77%. Average loans increased $176.6 million, while average deposits and available for sale investment securities, at fair value, decreased $135.0 million and $247.1 million, respectively, compared to the prior quarter. For the quarter, the return on average assets was 1.84%, the return on average equity was 14.70%, and the efficiency ratio was 58.40%.

Balance Sheet Review
During the 2nd quarter of 2026, average loans totaled $20.5 billion, an increase of $176.6 million over the prior quarter, and an increase of $3.0 billion over the same quarter last year. The increase in average balances over same quarter last year was primarily due to the acquisition of FineMark, which added $2.7 billion in loan balances on January 1, 2026. Compared to the previous quarter, average balances of business and consumer loans grew $177.2 million and $51.4 million, respectively, while average construction loan balances declined $46.7 million. During the current quarter, the Company sold certain fixed rate personal real estate loans totaling $15.9 million, compared to $26.2 million in the prior quarter.

Total average available for sale debt securities decreased $247.1 million from the previous quarter to $8.7 billion, at fair value. The decrease in available for sale debt securities was mainly the result of lower average balances of mortgage-backed and asset-backed securities, partly offset by higher average balances of U.S. government and federal agency obligations. During the 2nd quarter of 2026, the unrealized loss on available for sale debt securities decreased $68.9 million to $618.6 million, at period end. Also, during the 2nd quarter of 2026, purchases of available for sale debt securities totaled $810.0 million with a weighted average yield of approximately 4.21%. Sales, maturities and pay downs of available for sale debt securities were $1.2 billion, which included the sale of all the Company’s portfolio of U.S. Treasury inflation-protected securities (TIPS). On June 30, 2026, the duration of the available for sale investment portfolio was 4.2 years, and maturities and pay downs of approximately $1.1 billion are expected to occur during the next 12 months.

Total average deposits decreased $135.0 million this quarter compared to the previous quarter and increased $2.6 billion compared to the same quarter last year. The decrease in average balances compared to the prior quarter was primarily due to lower interest checking and money market deposits,
partly offset by higher non-interest bearing demand deposit balances, while the increase in average balances over the same quarter last year was primarily due to the FineMark acquisition.

Compared to the prior quarter, average interest checking and money market deposits decreased $249.2 million, while non-interest bearing demand deposits increased $160.3 million. Compared to the previous quarter, total average retail banking deposits grew $256.5 million, while commercial and wealth deposits declined $332.6 million and $61.4 million, respectively. The average loans to deposits ratio was 74.4% in the current quarter and 73.4% in the prior quarter. The Company’s average borrowings, which included average customer repurchase agreements of $2.3 billion, decreased $356.5 million to $2.6 billion in the 2nd quarter of 2026.

Net Interest Income
Net interest income in the 2nd quarter of 2026 amounted to $315.1 million, an increase of $15.2 million over the previous quarter. On a fully taxable-equivalent (FTE) basis, net interest income for the current quarter increased $15.3 million over the previous quarter to $317.5 million. The increase in net interest income was mostly due to higher interest income on loans and investment securities and lower interest expense on borrowing and deposits, partly offset by lower interest income on deposits with banks. Accretion income on FineMark’s loans resulting from purchase accounting adjustments totaled $6.2 million. The net yield (FTE) on earning assets increased to 3.77%, from 3.59% in the prior quarter.

Compared to the previous quarter, interest income on loans (FTE) increased $3.1 million, mostly due to higher average balances of business and consumer loans and higher average rates earned on business loans. These increases were partly offset by lower average balances and rates on construction loans. The average yield (FTE) on the loan portfolio decreased six basis points to 5.73% this quarter.

Interest income on investment securities (FTE) increased $10.4 million over the prior quarter, mostly due to higher average balances and rates earned on U.S. government and federal agency obligations and higher rates earned on other securities, partly offset by lower average balances of asset-backed and mortgage-backed securities. Interest income earned on U.S. government and federal agency obligations included $9.1 million in TIPS inflation income, a $9.6 million increase over the previous quarter. Interest income on other securities included dividend income of $863 thousand related to a private equity investment. Additionally, the Company recorded a $1.1 million adjustment to premium amortization at June 30, 2026, which increased interest income to reflect slower forward prepayment speed estimates on mortgage-backed securities. This increase was higher than the $940

Management Discussion of Second Quarter Results
June 30, 2026
thousand adjustment that increased interest income in the prior quarter. The average yield (FTE) on total investment securities was 3.42% in the current quarter, compared to 2.97% in the previous quarter.

Compared to the previous quarter, interest income on deposits with banks decreased $3.6 million due to lower average balances.

Interest expense decreased $4.4 million compared to the previous quarter, mainly due to lower average balances of deposits and borrowings. Interest expense on deposits decreased $2.3 million mostly due to lower average balances and rates paid on interest checking and money market deposit accounts. Interest expense on borrowings decreased $2.1 million mostly due to lower average balances of securities sold under agreements to repurchase. The average rate paid on interest bearing deposits was 1.57% in the current quarter compared to 1.61% in the prior quarter. The overall rate paid on interest bearing liabilities was 1.68% in the current quarter and 1.72% in the prior quarter.

Non-Interest Income
In the 2nd quarter of 2026, total non-interest income amounted to $183.8 million, an increase of $18.2 million, or 11.0%, over the same period last year and an increase of $8.0 million, or 4.5%, over the prior quarter. The increase in non-interest income over the same period last year was mainly due to higher trust fees and deposit account fees, partly offset by lower gains on sales of assets. The increase in non-interest income compared to the prior quarter was mainly due to higher bank card fee and swap fee income. Additionally, an increase of $2.5 million in fair value adjustments was recorded on the Company’s deferred compensation plan, which are held in a trust and recorded as both an asset and a liability, affecting both other income and other expense.

Total net bank card fees in the current quarter increased over the same period last year and the prior quarter by $1.8 million, or 3.8%, and $2.5 million, or 5.6%, respectively. Compared to the same period last year, net credit card fees increased $804 thousand, or 24.8%, primarily due to lower rewards expense, and net merchant fees increased $212 thousand, or 3.6%, primarily due to lower royalty expense and lower network expense. Net corporate card fees increased $811 thousand, or 3.1%, due to higher interchange fees, partly offset by higher rewards expense, while debit card fees decreased $68 thousand. Total net bank card fees this quarter were comprised of fees on corporate card ($26.7 million), debit card ($11.2 million), merchant ($6.1 million) and credit card ($4.0 million) transactions.

In the current quarter, trust fees increased $15.9 million, or 28.7%, over the same period last year, and increased $463 thousand, over the prior quarter, mostly resulting from higher private client fees. Compared to the same period last year, deposit
account fees increased $3.0 million, or 11.5%, mostly due to higher corporate cash management fees.

For the 2nd quarter of 2026, non-interest income comprised 36.8% of the Company’s total revenue.

Investment Securities Gains and Losses
The Company recorded net securities gains of $12.8 million in the current quarter, compared to net gains of $11.6 million in the prior quarter and $437 thousand in the 2nd quarter of 2025. Net securities gains in the current quarter resulted primarily from gains of $105.4 million recognized on Visa Inc. (“Visa”) common stock and $8.6 million on other equity securities. During the 2nd quarter of 2026, the Company sold 103 thousand shares of Visa Class A common stock (converted from 26 thousand shares of Visa Class C common stock) at an average price of $333.11. As of June 30, 2026, the Company has sold one third of the Visa Class C shares it received from the 2026 Visa exchange offer. Partly offsetting these gains, net fair value losses of $4.0 million were recorded on the Company’s portfolio of private equity investments. In addition, as a result of the completion of the Company’s previously disclosed repositioning of a portion of its available for sale debt securities portfolio, net losses of $97.7 million were realized during the quarter.

Non-Interest Expense
Non-interest expense for the current quarter amounted to $297.1 million, compared to $244.4 million in the same period last year and $291.1 million in the prior quarter. The increase in non-interest expense over the same period last year was mainly due to higher salaries and benefits expense, data processing and software expense, professional and other services expense, litigation expense, and intangible amortization expense. The increase in non-interest expense over the prior quarter was mainly due to higher salaries expense and litigation expense, partly offset by lower benefits expense and professional and other services expense.

Compared to the 2nd quarter of 2025, salaries and employee benefits expense increased $24.9 million, or 16.1%, mostly due to the onboarding of FineMark’s team members at the beginning of 2026. Acquisition-related salaries and benefits expense was $3.7 million in the current quarter. Full-time equivalent employees totaled 4,976 and 4,658 at June 30, 2026 and 2025, respectively.

Compared to the same period last year, data processing and software expense increased $5.3 million due to higher costs for service providers and software. Professional and other services expense increased $3.5 million compared to the 2nd quarter of 2025, and included $1.5 million in acquisition-related legal and professional services expense. The increase in other non-interest expense was mainly due to increases of $12.0 million in litigation expense

and $5.4 million in intangible amortization expense related to the FineMark acquisition.

Income Taxes
The effective tax rate for the Company was 22.3% in the current quarter, 22.4% in the prior quarter, and 21.8% in the 2nd quarter of 2025.

Credit Quality
Net loan charge-offs in the 2nd quarter of 2026 amounted to $9.5 million, compared to $15.0 million in the prior quarter, and $9.7 million in the same period last year. The ratio of annualized net charge-offs to total average loans was .19% in the current quarter, .30% in the previous quarter, and .22% in the same quarter of last year. Compared to the prior quarter, net charge-offs on business real estate loans decreased $5.4 million.

In the 2nd quarter of 2026, annualized net charge-offs on average consumer credit card loans were 5.18%, compared to 5.21% in the previous quarter and 5.08% in the same quarter last year. Consumer loan net charge-offs were .26% of average consumer loans in the current quarter, .30% in the prior quarter, and .40% in the same quarter last year.

At June 30, 2026, the allowance for credit losses on loans totaled $195.4 million, or .94% of total loans, and decreased $3.2 million compared to the prior quarter. Additionally, the liability for unfunded lending commitments on June 30, 2026 was $20.1 million, an increase of $2.4 million compared to the liability on March 31, 2026.

At June 30, 2026, total non-accrual loans amounted to $11.6 million, an increase of $698 thousand compared to the previous quarter.
