CULLEN/FROST REPORTS THIRD QUARTER RESULTS

Board declares fourth quarter dividend on common and preferred stock

SAN ANTONIO -- Cullen/Frost Bankers, Inc. (NYSE:CFR) today reported third quarter 2021 results.

Net income available to common shareholders for the third quarter of 2021 was $106.3 million compared to $95.1 million in the third quarter of 2020. On a per-share basis, net income available to common shareholders for the third quarter of 2021 was $1.65 per diluted common share, compared to $1.50 per diluted common share reported a year earlier. Returns on average assets and average common equity were 0.90 percent and 9.87 percent, respectively, for the third quarter of 2021 compared to 0.96 percent and 9.30 percent, respectively, for the same period a year earlier.

For the third quarter of 2021, net interest income on a taxable-equivalent basis was $269.3 million, up 0.9 percent, compared to the same quarter in 2020. Average loans for the third quarter of 2021 decreased $2.0 billion, or 10.8 percent, to $16.2 billion, from the $18.1 billion reported for the third quarter a year earlier. Excluding PPP loans, third quarter average loans of $14.8 billion represented a 0.8 percent decrease compared to the third quarter of 2020 and a 1.6 percent increase compared to the second quarter of 2021. Average deposits for the quarter were $39.1 billion, up $6.2 billion, or 19.0 percent, compared to the $32.9 billion reported for last year's third quarter.

“These results are reflective of a solid quarter, and we're optimistic going forward, both for the company and the economy in general,” said Phil Green, Cullen/Frost Chairman and CEO. “Loans are trending upward and headwinds associated with the pandemic's effects are beginning to diminish.

“Our team has made excellent progress helping our PPP borrowers through the forgiveness process, and I'm proud to report that approximately 85 percent of our PPP loans have been forgiven as of mid-October. At the same time, we've made investments to bolster access to our services and locations. We built strong relationships during these extraordinary times, and that puts us in a good position for the future.”

For the first nine months of 2021, net income available to common shareholders was $336.6 million, up 43.0 percent compared to $235.4 million for the first nine months of 2020. Diluted EPS available to common shareholders for the first nine months of 2021 was $5.22 compared to $3.71 in the year-earlier period, representing an increase of 40.7 percent. Returns on average assets and average common equity for the first nine months of 2021 were 1.00 percent and 10.72 percent, respectively, compared to 0.85 percent and 7.95 percent, respectively, for the same period in 2020.

Noted financial data for the third quarter of 2021 follows:

•The Common Equity Tier 1, Tier 1 and Total Risk-Based Capital Ratios at the end of the third quarter of 2021 were 13.42 percent, 14.01 percent and 15.90 percent, respectively, and continue to be in excess of well-capitalized levels and exceed Basel III minimum requirements.

•Net interest income on a taxable-equivalent basis was $269.3 million, an increase of 0.9 percent, compared to the prior year period. Net interest margin was 2.47 percent for the third quarter of 2021, down 18 basis points compared to the second quarter of 2021 net interest margin of 2.65 percent. Net interest margin decreased 48 basis points compared to 2.95 percent for the same period in 2020.

•Non-interest income for the third quarter of 2021 totaled $93.2 million, an increase of $9.6 million, or 11.5 percent, from the $83.6 million reported for the third quarter of 2020. Trust and investment

2

management fees increased $5.9 million, or 18.8 percent, compared to the third quarter of 2020. The increase in trust and investment management fees was primarily due to increases in investment management fees (up $3.6 million, or 13.1%), oil and gas fees (up $1.6 million) and custody fees (up $519,000). Service charges on deposit accounts increased $1.4 million or 7.1 percent compared to the third quarter of 2020. The increase was mainly driven by an increase in commercial service charges (up $1.1 million) and overdraft charges on commercial accounts (up $517,000) partly offset by a decrease in overdraft charges on consumer accounts (down $332,000). Other charges, commissions and fees increased $1.4 million, or 16.9 percent, compared to the third quarter of 2020. The increase was primarily related to an increase in income from the sale of mutual fund accounts (up $1.3 million).

•Non-interest expense was $218.0 million for the quarter, up $15.9 million, or 7.8 percent, compared to the $202.2 million reported for the third quarter a year earlier. Salaries and wages expense increased $6.1 million, or 6.6 percent, compared to the third quarter of 2020. The increase in salaries and wages during the comparable periods was primarily related to an increase in incentive compensation. Employee benefits expense of $21.6 million represented an increase of $5.5 million, or 34.2 percent, compared to the third quarter of 2020. The increase was mainly driven by an increase in certain discretionary benefit plan expenses. Technology, furniture and equipment expense increased $2.0 million, or 7.6 percent, compared to the third quarter of 2020. The increase was primarily related to increases in cloud services expense (up $1.4 million) and depreciation of furniture and equipment (up $604,000). Net occupancy expense increased $1.7 million, or 6.8 percent, compared to the third quarter of 2020. The increase was primarily related to increases in repairs and maintenance/service contracts expense (up $920,000) and depreciation on leasehold improvements (up $420,000), and was also impacted by our expansion activity in the Houston market area.

•For the third quarter of 2021, the company did not report a credit loss expense, and reported net charge-offs of $2.1 million. For the third quarter of 2020, the company recorded a $20.3 million credit loss expense and reported net charge-offs of $10.2 million. The allowance for credit losses on loans as a percentage of total loans was 1.58 percent at September 30, 2021, compared to 1.54 percent at the end of the second quarter of 2021 and 1.45 percent at the end of the third quarter of 2020. Excluding PPP loans,

3

which carry a guarantee from the SBA, the allowance for credit losses on loans as a percentage of total loans was 1.67 percent at the end of the third quarter of 2021, compared to 1.74 percent at the end of the second quarter of 2021 and 1.76 percent at the end of the third quarter of 2020. Non-accrual loans were $57.1 million at the end of the third quarter of 2021, compared to $57.3 million at the end of the second quarter of 2021 and $91.6 million at the end of the third quarter of 2020.

The Cullen/Frost board declared a fourth-quarter cash dividend of $0.75 per common share. The dividend on common stock is payable December 15, 2021 to shareholders of record on November 30 of this year. The board of directors also declared a cash dividend of $11.125 per share of Series B Preferred Stock (or $0.278125 per depositary share). The depositary shares representing the Series B Preferred Stock are traded on the NYSE under the symbol "CFR PrB." The Series B Preferred Stock dividend is payable on December 15, 2021, to shareholders of record on November 30 of this year.
