COMMERCE BANCSHARES, INC. REPORTS FIRST NINE
MONTHS EARNINGS PER SHARE GROWTH OF 14%

     Commerce Bancshares, Inc. announced record earnings of $2.47 per share for the nine months ended September 30, 2004, an increase of 14% compared to $2.17 per share during the same period in 2003. Net income for the first nine months of 2004 amounted to $167.7 million compared with $152.7 million in the same period last year, or an increase of 10%. During this period the return on average equity was 15.5%, the return on assets was 1.58%, and the efficiency ratio was 58.8%.

     For the three months ended September 30, 2004, earnings per share totaled $.93, an increase of 18% compared with $.79 in 2003. Net income amounted to $62.5 million compared with $54.9 million for 2003, an increase of 14%.

     In making this announcement, David W. Kemper, Chairman and CEO, said, “We are pleased to report double digit earnings per share growth for both the quarter and the first nine months of the year. For the first nine months, net income before taxes increased 11% as a result of growth in non-interest income, lower loan loss provisions and control over expenses. During this period, non-interest income grew by 11%, mainly the result of growth in bankcard income of 14%. Also, non-interest expense has grown by only 1% for the first nine months of this year. Net interest income this year, however, has remained flat when compared to the previous year as average loans have grown only 1% in this period. Net income for the third quarter of 2004 increased 14% over the same quarter last year and included the recognition of tax benefits of $14.0 million, which had been expected. Net income before taxes for the third quarter of 2004 increased 4%.”

     Mr. Kemper continued, “Asset quality remained solid this quarter with net charge-offs totaling $6.4 million compared with $6.2 million in the previous quarter and $9.7 million in the third quarter of last year. Our allowance for loan losses at September 30, 2004 totaled $133.4 million and was 522% of non-performing loans. Net charge-offs for the first nine months were .41% of average loans and our loan loss reserve remains at 1.63% of total loans.”

     Total assets at September 30, 2004 were $14.1 billion, total loans were $8.2 billion, and total deposits were $10.3 billion. Total non-performing loans amounted to $25.6 million or .31% of total loans.

Management Discussion of Third Quarter Results
September 30, 2004

For the quarter ended September 30, 2004, net income amounted to $62.5 million, an increase of 13.8% over the 3rd quarter of the previous year. Return on assets was 1.78% and the return on equity totaled 17.4%. For the quarter, the efficiency ratio was 59.2%. The increase in net income over the 3rd quarter of last year was the result of a reduction in income tax expense of $4.9 million coupled with growth in non-interest income of $2.0 million, and a $3.0 million reduction in the provision for loan losses. Non-interest expense increased 3.5% compared to the same quarter last year, and net interest income increased $1.7 million.

Balance Sheet Review
During the 3rd quarter, average loans were down slightly compared to the 2nd quarter of 2004, and were up almost 1% compared with the same period last year. Compared to the 2nd quarter of this year, average consumer, home equity, credit card and personal real estate loans grew by $25.9 million, $18.9 million, $14.2 million and $9.3 million, respectively, while business real estate loans, business loans and construction loans declined by $44.7 million, $44.4 million and $12.5 million, respectively. The increase in consumer loans was mainly the result of increases in marine and recreational vehicle lending. The decline in business loans, which occurred in the 3rd quarter, continued to reflect weak demand and lower line of credit usage. The decline in business real estate loans during the quarter was the result of larger pay offs during the quarter and customer refinancing activities.

Available for sale investment securities, excluding fair value adjustments, decreased on average by $254.7 million, or 5.1%, this quarter compared with the previous quarter. Most of this decline occurred towards the end of the previous quarter. Available for sale securities maturing during the 3rd quarter totaled $91.0 million while the principal amount of securities sold was $9.5 million. Early principal prepayments of mortgage and asset-backed securities totaled $246.0 million. Investment securities purchased in the current quarter totaled $278.4 million and were comprised of federal agency securities ($135.2 million), mortgage-backed securities ($85.2 million) and asset-backed securities ($34.7 million).

Total average deposits decreased slightly during the 3rd quarter compared to the 2nd quarter of this year. Average non-interest bearing deposits were relatively unchanged from the 2nd quarter. While total average interest bearing deposits were also flat compared with the previous quarter, money market accounts grew $28.2 million and interest checking accounts grew $13.0 million. Certificates of deposit, however, declined $54.9 million.

During the quarter, average borrowings decreased $311.6 million, primarily due to a decline in securities sold under agreements to repurchase.

The average loans to deposits ratio for the quarter decreased slightly to 77.8% in the 3rd quarter of 2004. The decrease in this ratio resulted from decreases in the average balances of both deposits and loans.

Net Interest Income
In the 3rd quarter, net interest income amounted to $123.7 million, an increase of $1.7 million, or 1.4%, compared to the 3rd quarter of last year, and a decrease of $2.8 million, or 2.2%, compared with the previous quarter of this year. The net yield on earning assets decreased 3 basis points from the previous quarter to 3.82% in the current quarter.

The decrease in net interest income in the 3rd quarter compared to the 2nd quarter of 2004 was the result of lower earnings on the Company’s inflation indexed treasury securities, lower average investment securities balances, and higher rates on short-term borrowings. This was partly offset by higher rates earned on virtually all lending products as a result of recent increases in rates by the Federal Reserve. Also, rates paid on interest bearing deposits grew only slightly during the current quarter. Compared to the 2nd quarter of 2004, average rates earned on loans increased 13 basis points while rates paid on interest bearing deposits increased 4 basis points. Average rates earned on investment securities decreased by 19 basis points, mainly a result of a $2.5 million decrease in inflation related earnings recognized in the 3rd quarter. The overall decline in securities balances reduced interest income by approximately $2.8 million.

During the quarter, rates on other borrowings increased by 32 basis points to 1.43% as a result of the higher rate environment, which especially affected short-term rates. The rate impact was partly offset by a decline in average borrowings of $311.6 million. This combination caused interest expense on other borrowings to grow by $874 thousand.

Non-Interest Income
For the 3rd quarter of 2004, total non-interest income amounted to $78.9 million compared with $76.9 million in the same quarter last year, an increase of 2.6%. This increase resulted from growth in deposit, bank card and trust fee income. Bond trading and mortgage banking fee income declined from amounts recorded in the same period last year due to slower customer demand. Bank card fees for the quarter increased 17.3% over the same period last year, due mainly to higher fees earned on merchant, debit card and credit card transactions, all of which grew by more than 10%. Deposit account fees, in the 3rd

quarter, grew 3.3% over last year due mainly to higher overdraft fees earned, while trust fees were up 3.9%, as a result of higher fees on institutional and corporate trust accounts. Other income in the 2nd quarter of 2004 included a gain on a branch sale of $1.1 million, which did not reoccur in the current quarter.

Net securities losses amounted to $148 thousand for the 3rd quarter of 2004, compared to net gains of $2.8 million in the 2nd quarter of 2004 and $896 thousand in the 3rd quarter of last year.

Non-Interest Expense
Non-interest expense for the quarter amounted to $120.5 million, an increase of $4.1 million, or 3.5%, compared with $116.4 million recorded in the 3rd quarter of last year. Year to date, non-interest expense in 2004 grew only 1.4% over the previous year, and was substantially unchanged when compared with the previous quarter.

Compared with the 3rd quarter of last year, salaries and benefits expense increased slightly as a result of higher salaries and health care expense offset partly by lower pension and incentive payments. Full-time equivalent employees totaled 4,821 and 4,986 at September 30, 2004 and 2003, respectively. Costs for supplies and communication, professional fees and operating losses all increased over amounts recorded in the 3rd quarter last year. Data processing costs grew $1.2 million, or 11.3%, mainly as a result of higher bank card processing network fees and software expense. Increased costs were also incurred for marketing and occupancy.

Income Taxes
During the 3rd quarter, income tax expense amounted to $13.0 million, a decrease of $16.7 million from the previous quarter and $4.9 million less than the same quarter last year. The lower income tax expense in the current quarter was the result of the recognition of tax benefits, totaling $14.0 million, associated with certain corporate tax reorganization initiatives which were finalized during the quarter. The Company will recognize an additional $5.0 million tax benefit related to these initiatives in the 4th quarter of this year. The effective tax rate for the Company was 17.2% for the 3rd quarter of 2004, compared with an effective tax rate of 35.5% in the 2nd quarter of 2004 and 24.6% in the 3rd quarter of 2003. The Company has additional income tax benefits totaling approximately $13.7 million associated with other corporate reorganization activities, which will not be recognized into income until certain conditions are satisfied. It is projected that such conditions may be resolved as early as the 3rd quarter of 2005.

Credit Quality
Net loan charge-offs for the 3rd quarter of 2004 amounted to $6.4 million compared with $6.2 million in the 2nd quarter of 2004 and $9.7 million in the 3rd quarter of last year. The ratio of annualized net loan charge-offs to total average loans this quarter was .31% compared with .48% in the same quarter last year and .31% in the 2nd quarter of 2004. The slight increase in net charge-offs this quarter compared with the 2nd quarter of this year was mainly the result of increases in consumer and business loan net charge-offs offset by a decrease in real estate net charge-offs.

For the 3rd quarter of 2004, annualized net charge-offs on average credit card loans decreased to 3.24%, compared with 3.66% in the 3rd quarter of last year. Personal loan (consumer, home equity and student) charge-offs increased this quarter over the 2nd quarter, and amounted to .42% of average personal loans compared to .27% in the 2nd quarter of 2004 and .45% in the same period last year. The provision for loan losses for the current quarter totaled $6.6 million, an increase of $326 thousand over the provision recorded in the 2nd quarter of this year, and was down $3.0 million from the amount recorded in the 3rd quarter of 2003. The allowance for loan losses at September 30, 2004 amounted to $133.4 million, or 1.63% of total loans, and represents 522% of total non-performing loans.

Total non-performing assets amounted to $27.1 million, a decrease of $2.4 million from the previous quarter, and amounted to .33% of loans. Non-performing assets are comprised of non-accrual loans ($25.6 million) and foreclosed real estate ($1.5 million). Loans past due more than 90 days and still accruing interest totaled $17.6 million at September 30, 2004.

During the quarter ended September 30, 2004, the Company purchased 752,000 shares of treasury stock at an average cost of $46.98 per share.
