CULLEN/FROST REPORTS SECOND QUARTER RESULTS

Board declares third quarter dividend on common and preferred stock

SAN ANTONIO -- Cullen/Frost Bankers, Inc. (NYSE:CFR) today reported second quarter 2018 results. Net income available to common shareholders for the second quarter of 2018 was $109.3 million, compared to $83.5 million in the second quarter of 2017, representing an increase of 31 percent. On a per-share basis, net income available to common shareholders for the second quarter of 2018 was $1.68 per diluted common share, compared to $1.29 per diluted common share reported a year earlier. Returns on average assets and average common equity were 1.43 percent and 14.03 percent, respectively, for the second quarter of 2018 compared to 1.11 percent and 11.07 percent, respectively, for the same period a year earlier.

For the second quarter of 2018 net interest income was $237.3 million, up 10.5 percent compared to the same quarter in 2017. Average loans for the second quarter of 2018 increased $1.3 billion or 10.3 percent, to $13.5 billion, from the $12.3 billion reported for the second quarter a year earlier. Average deposits for the quarter

were $26.1 billion compared to $25.7 billion reported for last year's second quarter, an increase of 1.6 percent.

“Our strong second-quarter earnings are the result of Frost bankers executing our strategy over the past several quarters,” said Cullen/Frost Chairman and CEO Phil Green. “Our commitment to sustainable, organic growth and providing an attractive value proposition has resonated with our customers and prospects. The Texas economy continued to grow robustly in the second quarter, with year-to-date job growth of 3.6 percent through May, and Frost bankers in all our regions continued to deliver great experiences for our customers.”

For the first six months of 2018, net income available to common shareholders was $213.8 million, up 28 percent compared to $166.5 million for the first six months of 2017. Diluted EPS available to common shareholders for the first six months was $3.30 compared to $2.57 in the year-earlier period. Returns on average assets and average common equity for the first six months of 2018 were 1.39 percent and 13.83 percent, respectively, compared to 1.11 percent and 11.31 percent, respectively, for the same period in 2017.

Noted financial data for the second quarter of 2018 follows:

• The Common Equity Tier 1, Tier 1 and Total Risk-Based Capital Ratios at the end of the second quarter of 2018 were 12.69 percent, 13.40 percent and 15.29 percent, respectively, and continue to be in excess of well-capitalized levels. Current capital ratios exceed Basel III fully phased-in requirements.

• Net interest income of $237.3 million represented a 10.5 percent increase over the prior year period. Net interest margin was 3.64 percent for the second quarter of 2018, a 12 basis point increase over the first quarter of 2018 net interest margin of 3.52 percent. This compares to 3.70 percent in the second quarter of 2017 based on a 35 percent tax rate, and 3.38 percent had the current 21 percent tax rate been in place.

• Non-interest income for the second quarter of 2018 totaled $85.1 million, an increase of $4.0 million, or 4.9 percent, compared to $81.1 million reported for the second quarter of 2017. Other non-interest income totaled $11.6 million, increasing $4.7 million compared to the second quarter of 2017. This increase was primarily related to recoveries of prior write-offs of $1.7 million, distributions on private equity investments of $1.2 million, and gains on the sale of properties of $885,000. Trust and investment management fees were $29.1 million, up $1.4 million, or 5.0 percent, from the second quarter of 2017. The increase was primarily driven by higher trust investment fees and oil and gas fees. Insurance

2

commissions and fees were $10.6 million, up $828,000 or 8.5 percent, compared to the $9.7 million reported in the second quarter a year earlier.

• Non-interest expense was $188.9 million for the second quarter of 2018, up $857,000 or 0.5 percent compared to the $188.1 million reported for the second quarter a year earlier. Total salaries rose $4.2 million, or 5.2 percent, to $85.2 million, and were impacted by an increase in the number of employees and by normal annual merit and market increases, as well as an increase in incentive compensation. Technology, furniture and equipment expense for the second quarter increased by $2.2 million, or 12.1 percent, from the second quarter of 2017. The increase was primarily driven by increases in software maintenance, software amortization, and service contracts expense. Other non-interest expense was $40.9 million in the second quarter of 2018, a decrease of $4.5 million, or 10.0 percent, from the second quarter a year earlier. A decrease in fraud losses (down $2.2 million) and lower advertising/promotions expense (down $1.9 million) were partly offset by costs related to our previously mentioned data security incident of $937,000, settlement costs of $879,000, and a $500,000 contribution to our charitable foundation.

• For the second quarter of 2018, the provision for loan losses was $8.3 million, while net charge-offs totaled $7.9 million. This compares with a provision for loan losses of $6.9 million and $12.4 million in net charge-offs for the first quarter of 2018, and a provision for loan losses of $8.4 million and $11.9 million in net charge-offs in the second quarter of 2017. The allowance for loan losses as a percentage of total loans was 1.10 percent at June 30, 2018, compared to 1.12 percent at the end of the first quarter of 2018 and 1.20 percent at the end of the second quarter of 2017. Non-performing assets were $122.8 million at the end of the second quarter of 2018, compared to $136.6 million at the end of the first quarter of 2018 and $90.2 million at the end of the second quarter of 2017.

• The interchange and debit card transaction fees category of non-interest income and the other expense category were each impacted by our adoption at the beginning of 2018 of a new accounting standard that affects how we report revenues and network costs associated with ATM and debit card network transactions. Prior to 2018, we recognized such revenues and network costs on a gross basis. Beginning in 2018, ATM and debit card transaction fees are reported net of related network costs. For the three months

3

ended June 30, 2018, gross interchange and debit card transaction fees totaled $6.5 million while related network costs totaled $3.0 million. On a net basis, we reported $3.4 million as interchange and debit card transaction fees. See note 2 on page 6 of this release, and our forthcoming form 10-Q for more information on the effects of this and other accounting changes.

The Cullen/Frost board declared a third quarter cash dividend of $0.67 per common share, payable on September 14, 2018, to shareholders of record on August 31, 2018. The board of directors also declared a cash dividend of

$0.3359375 per share of the Noncumulative Perpetual Preferred Stock, Series A, which trades on the NYSE under the symbol "CFR PrA." The Series A Preferred Stock dividend is payable on September 17, 2018, to shareholders of record on August 31, 2018.
