COMMERCE BANCSHARES, INC. REPORTS

FOURTH QUARTER EARNINGS PER SHARE OF $.96

Commerce Bancshares, Inc. announced earnings of $.96 per common share for the three months ended December 31, 2018 compared to $.82 per share in the same quarter last year and $.98 per share in the prior quarter. Net income attributable to Commerce Bancshares, Inc. for the fourth quarter of 2018 amounted to $109.7 million, compared to $94.4 million in the fourth quarter of 2017 and $112.6 million in the prior quarter. For the current quarter, the return on average assets was 1.75%, the return on average common equity was 15.9%, and the efficiency ratio was 54.5%.

For the year ended December 31, 2018, earnings per common share totaled $3.78 compared to $2.76 in 2017, or an increase of 37%. Net income attributable to Commerce Bancshares, Inc. for the year ended December 31, 2018 increased 36% to $433.5 million compared to $319.4 million last year. For the current year, the return on average assets was 1.76% and the return on average common equity was 16.2%.

In making this announcement, John Kemper, Chief Executive Officer, said, “This quarter we continued to see strong earnings performance as revenue increased $13.8 million, while expenses and credit costs were well controlled. Compared to the prior quarter, net interest income increased $4.5 million, while our net interest margin increased six basis points to 3.58%. The yield on our loan portfolio grew 13 basis points, while funding costs increased only modestly. The diversity of our fee businesses drove growth in non-interest income, which increased $9.4 million this quarter. This growth came from higher bank card, brokerage, swap, and tax credit fees. It also included net gains on branch sales of $7.7 million. Demand for business and business real estate loans improved this quarter and as a result, we experienced growth in new loans and increased line utilization, while seasonal paydowns on some lines of credit partially offset this growth. Average deposits declined slightly.”

Mr. Kemper added, “Overall the economy appears solid and the credit environment remains favorable. Capital and liquidity levels continue to remain very strong. Net loan charge-offs this quarter totaled $12.1 million compared to $9.8 million in the prior quarter and $11.0 million in the same quarter last year. The increase in net loan charge-offs over the prior quarter was mainly due to increased losses of $1.4 million on business loans and higher net loan charge-offs on the Company’s consumer loan portfolio. Credit card net charge-offs remained stable and declined as a percentage of loans this quarter. The ratio of annualized net loan charge-offs to average loans was .34% this quarter compared to .28% last quarter. Non-performing assets increased this quarter to $13.9 million, and the provision for loan losses totaled $12.3 million. At December 31, 2018, the allowance for loan losses amounted to $159.9 million, or 1.13% of period end loans.”

Management Discussion of Fourth Quarter Results

December 31, 2018

For the quarter ended December 31, 2018, net income attributable to Commerce Bancshares, Inc. (net income) amounted to $109.7 million, compared to $112.6 million in the previous quarter and $94.4 million in the same quarter last year. During the 4^th quarter of 2018, non-recurring income totaling $2.9 million ($2.3 million net of tax) was recorded and included a net gain of $7.7 million from the disposition of several branch properties, net securities losses of $7.3 million, and discrete interest and dividends of $2.5 million from the Company’s private equity investments (net of minority interest). Overall the net interest margin grew six basis points, mainly due to higher loan rates and stable funding costs. Excluding the branch gains, non-interest income grew $1.7 million compared to the prior quarter from continued growth in the Company’s diverse revenue sources including bank card, tax credit, swap and brokerage fees. Non-interest expense increased $3.6 million this quarter due to higher salaries and marketing costs. Quarterly average loans increased $92.6 million this quarter over the previous quarter, while average deposits decreased $35.6 million. For the quarter, the return on average assets was 1.75%, the return on average common equity was 15.9%, and the efficiency ratio was 54.5%.

Balance Sheet Review

During the 4^th quarter of 2018, average loans totaled $14.0 billion, an increase of $92.6 million over the prior quarter, and grew $204.0 million, or 1.5%, over the same period last year. Period-end loans, however, increased $188.5 million over the prior quarter. Compared to the previous quarter, average business, business real estate, consumer card, and personal real estate loans grew $102.6 million, $24.6 million, $13.8 million, and $11.4 million, respectively. However, this growth was partly offset by a decline in average construction (decline of $38.9 million) and auto (decline of $12.5 million) lending activities. Business loan demand was solid this quarter with several new large loans closed and increased line utilization, notably from agribusiness customers, but this growth was partly offset by some large seasonal loan paydowns. Several larger business real estate loans were also closed this quarter. The decline in construction loans resulted from projects being completed and loans either moved to permanent financing on balance sheet (business real estate) or financed outside of the bank. Also, personal real estate loans grew modestly due to continued demand for adjustable rate mortgages which are kept on-balance sheet. Consumer loans declined $22.2 million due to lower demand for automobile lending and fixed home equity loans. Consumer card balances grew throughout the year and were seasonally higher in the 4^th quarter of 2018. During the current quarter, the Company sold certain fixed rate personal real estate loans totaling $49.7 million, compared to $56.1 million in the prior quarter.

During the 4^th quarter of 2018, total average available for sale debt securities decreased $71.3 million from the previous quarter to $8.6 billion, at fair value. The decrease in investment securities was mainly the result of lower mortgage-backed, government-sponsored enterprise obligations and municipal securities, partly offset by higher average balances of asset-backed securities. Purchases of securities during the quarter totaled $597.8 million and were offset by sales, maturities and pay downs of $820.0 million. At December 31, 2018, the duration of the investment portfolio was 3.2 years, and maturities and pay downs of approximately $1.0 billion are expected to occur during the next 12 months.

Total average deposits decreased $35.6 million this quarter compared to the previous quarter. The decrease in average deposits resulted mainly from lower balances of certificates of deposit (decline of $18.9 million), savings (decline of $6.5 million), and personal and government demand deposits (decline of $79.9 million). These declines were partially offset by a $60.9 million increase in business demand deposits this quarter. Overall, compared to the previous quarter, total average consumer and wealth (including private banking) deposits decreased $59.2 million and $20.4 million, respectively, while average commercial banking deposits grew $46.9 million. The average loans to deposits ratio was 69.9% in the current quarter and 69.3% in the prior quarter. The Company’s average borrowings were $1.7 billion in the 4^th quarter of 2018, an increase of $155.7 million over the prior quarter’s balance.

Net Interest Income

Net interest income in the 4^th quarter of 2018 amounted to $212.2 million compared to $207.8 million in the previous quarter, an increase of $4.5 million. On a tax equivalent basis, net interest income for the current quarter increased $4.9 million over the previous quarter to $216.3 million. As noted previously, net interest income included non-recurring dividend and interest of $3.1 million in the current quarter and $2.0 million in the prior quarter from the Company’s private equity investments. Also, inflation income on the Company’s inflation protected securities (TIPs) declined $980 thousand this quarter. Excluding these items, net interest income grew $4.5 million and the adjusted net yield on earning assets (tax equivalent) was 3.50% compared to 3.45% in the prior quarter.

Compared to the previous quarter, interest income on loans (tax equivalent) increased $5.6 million as a result of higher overall loan yields coupled with growth, mainly in business loan balances. The average tax-equivalent yield on the loan portfolio increased 13 basis points this quarter to 4.72%, compared to 4.59% in the previous quarter.

Interest income on investment securities (tax equivalent) increased $2.2 million over the previous quarter, mainly due to higher rates and balances on the Company’s asset-backed securities and the discrete dividends received on the Company’s equity investments noted above. Also, the adjustment for premium amortization expense on slowing prepayment speeds for mortgage-backed and asset-backed securities increased interest income $670 thousand this quarter. However, inflation income on TIPs securities declined $980 thousand to $1.5 million this quarter. The yield on total investment securities was 2.86% in the current quarter and 2.76% in the previous quarter.

Interest costs on deposits remained low and totaled 41 basis points in the 4^th quarter of 2018, compared to 35 basis points in the prior quarter. Interest expense on deposits increased $2.0 million this quarter compared to the previous quarter mainly due to higher rates on most deposit categories. Borrowing costs increased $1.7 million this quarter mainly due to higher rates and balances of customer repurchase agreements. The overall rate paid on interest bearing liabilities was .54% in the current quarter, compared to 45% in the prior quarter.

Non-Interest Income

In the 4^th quarter of 2018, total non-interest income amounted to $133.1 million, an increase of $13.7 million, or 11.5%, compared

COMMERCE BANCSHARES, INC.

Management Discussion of Fourth Quarter Results

December 31, 2018

to the same period last year and increased $9.4 million compared to the prior quarter. The current quarter includes net gains of $7.7 million from the disposition of several branch properties (included in other income). Excluding this gain, the increase in non-interest income over the same period last year was mainly due to growth in trust, bank card, deposit, tax credit and brokerage fees.

Total bank card fees in the current quarter increased $1.6 million, or 3.7%, over the same period last year and grew $2.1 million, or 4.8%, compared to the prior quarter. Corporate card net fees grew $2.7 million, or 11.6%, over the same quarter last year mainly due to growth in interchange income from increased customer activity. Debit card net fees grew $219 thousand, or 2.2%, driven by growth in fees of 5.9% but offset by higher network processing costs. Overall net merchant income declined $662 thousand due to lower interchange fees and higher processing costs, while net credit card fees declined $674 thousand on higher rewards costs, partly offset by higher interchange revenue. Total net bank card fees this quarter were comprised of fees on corporate card ($26.1 million), debit card ($10.2 million), merchant ($4.4 million) and credit card ($3.8 million) transactions.

In the current quarter, trust fees increased $2.1 million, or 5.8%, over the same period last year, resulting from growth in private client fee income. Compared to the same period last year, deposit account fees increased $1.3 million, or 5.7%, mainly due to growth in corporate cash management fees and consumer deposit fees.

During the 4^th quarter of 2018, brokerage fees grew 17.0% over the same period last year to $4.2 million, while cash sweep fees grew 26.4% to $2.6 million. Gains on sales of tax credits totaled $2.0 million this quarter, reflecting an increase of $1.3 million over amounts reported in the same quarter last year. Non-interest income comprised 38.5% of the Company’s total revenue this quarter.

Investment Securities Gains and Losses

The Company recorded net securities losses of $7.1 million in the current quarter, compared to net securities gains of $4.3 million in the prior quarter and $27.2 million in the 4^th quarter of 2017. This quarter, the Company sold securities with a book value of $523.9 million, mainly U.S. Treasury securities, and recorded securities losses of $10.1 million. The proceeds from this sale were reinvested in similar securities with higher rates. Also, gains of $3.1 million (realized and fair value adjustments) were recorded on the Company’s private equity portfolio this quarter.

Non-Interest Expense

Non-interest expense for the current quarter amounted to $188.6 million, compared to $208.9 million in the same period last year and $185.1 million in the prior quarter. The decrease in expense compared to the same period last year was mainly due to a $25.0 million contribution of appreciated securities and a $3.3 million discretionary bonus accrual in 2017 that did not reoccur in 2018, partly offset by higher salaries and benefits, data processing and marketing costs in 2018.

Compared to the 4^th quarter of last year, salaries and benefits expense increased $4.8 million, or 4.1%. Salaries expense grew $3.5 million, due to higher full-time salary costs of $6.3 million, while incentive compensation decreased $3.2 million due to the discretionary bonus mentioned above. Benefits expense increased $1.3 million, due to higher medical, payroll taxes and retirement

plan costs. Full-time equivalent employees totaled 4,795 and 4,800 at December 31, 2018 and 2017, respectively.

Marketing costs increased $1.7 million partly due to increased marketing efforts to consumer deposit customers and new bank card initiatives. However, deposit insurance expense declined $1.6 million due to reduced FDIC insurance rates in effect this quarter, partly offsetting the increase in marketing expense. Also, supplies and communication expense declined $1.0 million this quarter on lower data network and postage costs, while data processing costs increased $1.1 million due to higher software expense.

Income Taxes

The effective tax rate for the Company was 19.5% in the current quarter, 19.1% in the previous quarter, and 17.6% in the 4^th quarter of 2017.

Credit Quality

Net loan charge-offs in the 4^th quarter of 2018 amounted to $12.1 million, compared to $9.8 million in the prior quarter and $11.0 million in the same period last year. The ratio of annualized net loan charge-offs to total average loans was .34% in the current quarter, compared to .28% in the previous quarter and .32% in the 4^th quarter of last year. During the 4^th quarter of 2018, the Company recorded net loan charge-offs on commercial loans of $1.5 million mainly representing one larger business loan. Net loan charge-offs on personal banking loans totaled $10.6 million in the current quarter and $9.6 million in the previous quarter.
