COMMERCE BANCSHARES, INC. REPORTS

THIRD QUARTER EARNINGS PER SHARE OF $1.06

Commerce Bancshares, Inc. announced earnings of $1.06 per share for the three months ended September 30, 2025, compared to $1.01 per share in the same quarter last year and $1.14 per share in the second quarter of 2025. Net income for the third quarter of 2025 amounted to $141.5 million, compared to $138.0 million in the third quarter of 2024 and $152.5 million in the prior quarter.

For the nine months ended September 30, 2025, earnings per share totaled $3.18, compared to $2.86 for the first nine months of 2024. Net income amounted to $425.6 million for the nine months ended September 30, 2025, compared to $390.2 million in the comparable period last year. For the year to date, the return on average assets was 1.81%, and the return on average equity was 16.15%.

In making this announcement, John Kemper, Chief Executive Officer, said, “Commerce delivered another strong quarter, underscoring the resilience of our diversified operating model and the dedication of our talented team. Our third quarter results reflect steady loan balances, robust fee income, and disciplined expense management, all of which contributed to another period of high profitability.

“Our return on average assets remained solid at 1.78%, and our return on average equity was 15.26%. We maintained excellent credit quality, with non-accrual loans at just .09% of total loans, and added a modest reserve to the allowance for credit losses. Our capital and liquidity positions remain strong, supporting our ability to serve customers and invest in future growth.

“Net interest income was $279.5 million, reflecting the continued benefits of our strong balance sheet, even as the interest rate environment remains dynamic. Non-interest income was $161.5 million, led by growth in trust and deposit fees, and comprised 36.6% of total revenue.”

Mr. Kemper continued, “We look forward to welcoming FineMark's team, clients, and shareholders to Commerce on January 1, 2026, our expected close date, which will mark a strategic milestone after years of relationship building and months of integration planning by our dedicated teams.

“As we continue to build on our momentum, our franchise is well-positioned to execute on our long-term strategies, deliver value to our shareholders, and support our customers and communities.”

Management Discussion of Third Quarter Results

September 30, 2025

For the quarter ended September 30, 2025, net income amounted to $141.5 million, compared to $152.5 million in the previous quarter and $138.0 million in the same quarter last year. The decrease in net income compared to the previous quarter was primarily the result of an increase in the provision for credit losses and lower non-interest income, partly offset by higher gains on investment securities. The net yield on interest earning assets decreased six basis points from the previous quarter. Average loans were flat, while average available for sale investment securities, at fair value, and deposits decreased $214.5 million and $140.1 million, respectively, compared to the prior quarter. For the quarter, the return on average assets was 1.78%, the return on average equity was 15.26%, and the efficiency ratio was 55.3%.

Balance Sheet Review

During the 3rd quarter of 2025, average loans totaled $17.5 billion, flat compared to the prior quarter, and an increase of $468.5 million over the same quarter last year. Compared to the previous quarter, average balances of business real estate loans grew $23.2 million, while construction and business loans declined $33.8 million and $17.2 million, respectively. During the current quarter, the Company sold certain fixed rate personal real estate loans totaling $30.6 million, compared to $19.7 million in the prior quarter.

Total average available for sale debt securities decreased $214.5 million compared to the previous quarter to $8.9 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. During the 3rd quarter of 2025, the unrealized loss on available for sale debt securities decreased $75.9 million to $688.5 million, at period end. Also, during the 3rd quarter of 2025, purchases of available for sale debt securities totaled $459.3 million with a weighted average yield of approximately 4.15%, and maturities and pay downs of available for sale debt securities were $456.7 million. On September 30, 2025, the duration of the available for sale investment portfolio was 4.4 years, and maturities and pay downs of approximately $1.3 billion are expected to occur during the next 12 months.

Total average deposits decreased $140.1 million this quarter compared to the previous quarter. The decrease in deposits mostly resulted from lower average interest checking and money market balances of $160.9 million. Compared to the previous quarter, total average wealth and consumer deposits declined $132.4 million and $111.1 million, respectively, while average commercial deposits grew $118.1 million. The average loans to deposits ratio was 70.6% in the current quarter and 70.2% in the prior quarter. The Company’s average borrowings, which included average customer repurchase agreements of $2.5 billion, increased $148.5 million to $2.7 billion in the 3rd quarter of 2025.

Net Interest Income

Net interest income in the 3rd quarter of 2025 amounted to $279.5 million, a decrease of $690 thousand compared to the previous quarter. On a fully taxable-equivalent (FTE) basis, net interest income for the current quarter decreased $658 thousand compared to the previous quarter to $281.8 million. The decrease in net interest income was mostly due to lower interest income on investment securities and higher interest expense on borrowings and deposits, partly offset by higher interest income on loans and deposits with banks. The net yield (FTE) on earning assets decreased to 3.64%, from 3.70% in the prior quarter.

Compared to the previous quarter, interest income on loans (FTE) increased $3.5 million, mostly due to an additional day of interest earned in the 3rd quarter, partly offset by lower average balances of construction loans. The average yield (FTE) on the loan portfolio increased one basis point to 6.02% this quarter.

Interest income on investment securities (FTE) decreased $5.6 million compared to the prior quarter, mostly due to lower average balances of asset-backed and mortgage-backed securities and lower rates on U.S. government and federal agency securities and other securities, partially offset by higher average balances of U.S. government and federal agency securities. Interest income earned on U.S. government and federal agency securities included the impact of a $1.1 million decline in inflation income from Treasury inflation-protected securities compared to previous quarter. Interest on other securities included $1.3 million of non-accrual interest income related to a private equity investment but was lower than the $1.8 million of dividend and non-accrual interest recorded in the prior quarter. Additionally, the Company recorded a $314 thousand adjustment to premium amortization on September 30, 2025, which increased interest income to reflect slower forward prepayment speed estimates on mortgage-backed securities. This increase was lower than the $1.0 million adjustment that increased interest income in the prior quarter. The average yield (FTE) on total investment securities was 2.99% in the current quarter, compared to 3.16% in the previous quarter.

Compared to the previous quarter, interest income on deposits with banks increased $4.5 million, due to higher average balances.

Interest expense increased $3.2 million compared to the previous quarter, mainly due to higher average rates paid on deposits and higher average balances of borrowings. Interest expense on borrowings increased $1.4 million mostly due to an increase of $148.6 million in average securities sold under repurchase agreement balances. Interest expense on deposits increased $1.8 million mostly due to higher average rates. The average rate paid on interest bearing deposits totaled 1.71% in the current quarter compared to 1.67% in the prior quarter. The overall rate paid on interest bearing liabilities was

Exhibit 99.1

COMMERCE BANCSHARES, INC.

Management Discussion of Third Quarter Results

September 30, 2025

1.87% in the current quarter and 1.83% in the prior quarter.

Non-Interest Income

In the 3rd quarter of 2025, total non-interest income amounted to $161.5 million, an increase of $2.5 million, or 1.6%, over the same period last year and a decrease of $4.1 million compared to the prior quarter. The increase in non-interest income compared to the same period last year was mainly due to higher trust fees, deposit account fees and brokerage fees, partly offset by lower bank card fees and lower gains on sales of assets. The decrease in non-interest income compared to the prior quarter was mainly due to lower gains on sales of assets of $6.5 million, partly offset by higher trust fees.

Total net bank card fees in the current quarter decreased $2.0 million, or 4.2%, compared to the same period last year, and decreased $811 thousand compared to the prior quarter. Net corporate card fees decreased $1.7 million compared to the same quarter of last year mainly due to higher rewards expense, partly offset by higher interchange fees. Net merchant fees increased $89 thousand, or 1.6%, while net debit card fees decreased $107 thousand, or .9%. Net credit card fees decreased $336 thousand, or 8.5%, mostly due to higher rewards expense. Total net bank card fees this quarter were comprised of fees on corporate card ($25.1 million), debit card ($11.3 million), merchant ($5.6 million) and credit card ($3.6 million) transactions.

In the current quarter, trust fees increased $3.7 million, or 6.8%, over the same period last year, mostly resulting from higher private client fees. Compared to the same period last year, deposit account fees increased $2.0 million, or 8.1%, mostly due to higher corporate cash management fees, while consumer brokerage fees increased $2.1 million.

Other non-interest income decreased compared to the same period last year primarily due to lower gains on sales of assets of $4.7 million. For the 3rd quarter of 2025, non-interest income comprised 36.6% of the Company’s total revenue.

Investment Securities Gains and Losses

The Company recorded net securities gains of $7.9 million in the current quarter, compared to $437 thousand in the prior quarter and $3.9 million in the 3rd quarter of 2024. Net securities gains in the current quarter mostly resulted from net fair value adjustments of $8.0 million on the Company’s portfolio of private equity investments.

Non-Interest Expense

Non-interest expense for the current quarter amounted to $244.0 million, compared to $237.6 million in the same period last year and $244.4 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, and professional and other services expense.

Compared to the 3rd quarter of 2024, salaries and employee benefits expense increased $4.3 million, or 2.8%, mostly due to higher full-time salaries of $3.0 million and higher incentive compensation of $1.4 million, partly offset by lower healthcare expense of $805 thousand. Full-time equivalent employees totaled 4,666 and 4,711 on September 30, 2025 and 2024, respectively.

Compared to the same period last year, data processing and software expense increased $1.4 million due to higher costs for service providers and software. Professional and other services, which increased $2.5 million compared to the 3rd quarter of 2024, included $1.1 million of acquisition related legal and professional services expense. Other non-interest expense decreased mainly due to a $1.5 million reimbursement during the 3rd quarter of 2025 related to a litigation settlement.

Income Taxes

The effective tax rate for the Company was 22.5% in the current quarter, 21.8% in the prior quarter, and 21.7% in the 3rd quarter of 2024. The increase in the effective tax rate compared to the prior quarter was mostly due to tax law changes enacted in the prior quarter that decreased the effective tax rate. The increase in the effective tax rate compared to the 3rd quarter of 2024 was mostly due to higher state and local income taxes.

Credit Quality

Net loan charge-offs in the 3rd quarter of 2025 amounted to $10.3 million, compared to $9.7 million in the prior quarter, and $9.6 million in the same period last year. The ratio of annualized net loan charge-offs to total average loans was .23% in the current quarter, .22% in the previous quarter, and .22% in the same quarter of last year. Compared to the prior quarter, net loan charge-offs on business real estate, business and personal real estate loans increased $402 thousand, $394 thousand and $234 thousand, respectively, while net charge-offs on consumer credit card loans decreased $570 thousand.

In the 3rd quarter of 2025, annualized net loan charge-offs on average consumer credit card loans were 4.59%, compared to 5.08% in the previous quarter and 4.46% in the same quarter last year. Consumer loan net charge-offs were .42% of average consumer loans in the current quarter, .40% in the prior quarter, and .52% in the same quarter last year.

On September 30, 2025, the allowance for credit losses on loans totaled $175.7 million, or .99% of total loans, and increased $10.4 million compared to the prior quarter. The increase in the allowance for credit losses on loans was primarily due to weakness in soft commodity prices impacting certain industries. Additionally, the liability for unfunded lending commitments on September 30, 2025 was $15.3 million, a decrease of $678 thousand compared to the liability on June 30, 2025.

On September 30, 2025, total non-accrual loans amounted to $16.3 million, a decrease of $2.6 million
