CULLEN/FROST REPORTS 4^th QUARTER AND 2018 ANNUAL RESULTS

Board declares first quarter dividend on common and preferred stock

SAN ANTONIO - Cullen/Frost Bankers, Inc. (NYSE:CFR) today reported fourth quarter and annual results for 2018. Cullen/Frost reported net income available to common shareholders for the fourth quarter of 2018 of $117.2 million, or $1.82 per diluted common share, both up 19 percent compared to fourth quarter 2017. For the fourth quarter of 2018, returns on average assets and common equity were 1.48 percent and 14.85 percent, respectively, compared to 1.26 percent and 12.66 percent for the same period in 2017.

The company also reported 2018 annual net income available to common shareholders of $446.9 million, an increase of 25.5 percent compared to 2017 earnings of $356.1 million. On a per-share basis, 2018 earnings were $6.90 per diluted common share, compared to $5.51 per diluted common share reported in 2017. For the year 2018, returns on average assets and common equity were 1.44 percent and 14.23 percent respectively, compared to 1.17 percent and 11.76 percent reported in 2017.

“Our solid fourth-quarter and full-year 2018 earnings resulted from our continued, consistent execution of our plan,” said Phil Green, Cullen/Frost chairman and CEO. “We continue to realize high-single-digit loan growth while pursuing consistent, above-market, profitable organic growth across our enterprise.

“We also continue to execute on our Houston expansion efforts,” Green said. “We opened the first of the 25 new financial centers planned over the next two years in the Houston area just before the end of the fourth quarter.”

During the fourth quarter of 2018, average loans increased 8.3 percent to $13.9 billion, up approximately $1.1 billion compared to $12.9 billion in the fourth quarter of 2017. Average deposits rose by 0.5 percent to $26.5 billion, up $123.7 million from the $26.4 billion reported in the fourth quarter of 2017. Average demand deposits were down $358 million, or 3.2 percent. This decrease was offset by a continued increase in average interest-bearing deposits, which were up $482 million or 3.2 percent compared to the fourth quarter of 2017.

For 2018, average total loans were $13.6 billion, an increase of approximately $1.2 billion, or 9.3 percent, from the $12.5 billion reported the previous year. Average total deposits for 2018 increased to $26.3 billion, up 1.5 percent, or $384.1 million, over the $25.9 billion reported in 2017.

Noted financial data for the fourth quarter:

• The Common Equity Tier 1, Tier 1 and Total Risk-Based Capital Ratios for Cullen/Frost at the end of the fourth quarter of 2018 were 12.65 percent, 13.34 percent, and 15.09 percent, respectively. Current capital ratios continue to be in excess of well-capitalized levels and exceed Basel III fully phased-in requirements.

• Net interest income for the fourth quarter totaled $249.2 million, an increase of 11.3 percent compared to the $223.9 million reported for the fourth quarter of 2017. The net interest margin was 3.72 percent for the fourth quarter compared to 3.70 percent for the fourth quarter of 2017 and 3.66 percent for the third quarter of 2018. Had the current 21 percent corporate tax rate been in place, fourth quarter 2017 net interest margin

2

would have been 3.39 percent. A shift in the mix of earning assets to higher yielding assets, primarily loans, and higher interest rates positively affected the net interest margin compared to a year ago.

• Non-interest income for the fourth quarter of 2018 was $87.1 million, down $3.0 million from the $90.1 million reported a year earlier. Other income decreased $1.0 million, impacted by higher gains on the sale of properties recorded in the fourth quarter last year. The year-on-year comparison for the interchange and debit card transaction fees line of non-interest income was negatively impacted by $3.0 million related to the change in accounting standard addressed in the last bullet below.

• Non-interest expense for the fourth quarter of 2018 was $199.7 million, up $3.4 million, or 1.7 percent, compared to the $196.3 million reported for the fourth quarter of 2017. Technology, furniture and equipment expense was up $2.6 million. The increase was primarily driven by a $1.4 million increase in software maintenance expense. Employee benefits expense increased $2.0 million, or 12.0 percent, impacted by higher medical benefits expense. Deposit insurance decreased $2.6 million, primarily due to the elimination of the surcharge during the fourth quarter as the Deposit Insurance Fund reached the prescribed reserve level set by the FDIC. Other non-interest expense of $47.5 million increased 0.4 percent compared to the fourth quarter of 2017. Adjusted for the accounting change related to interchange and ATM-related expenses, other non-interest expense would have increased $3.0 million or 6.8 percent. Other non-interest expense in the fourth quarter of 2018 was impacted by higher advertising/marketing expenses, up $2.6 million from a year earlier.

• For the fourth quarter of 2018, the provision for loan losses was $3.8 million, compared to net charge-offs of $9.2 million. For the fourth quarter of 2017, the provision for loan losses was $8.1 million, compared to net charge-offs of $7.0 million. The allowance for loan losses as a percentage of total loans was 0.94 percent at December 31, 2018, compared to 1.00 percent last quarter and 1.18 percent at year-end 2017. Non-performing assets were $74.9 million at year end, compared to $86.4 million the previous quarter, and $157.3 million at year-end 2017.

3

• 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 fourth quarter of 2018, gross interchange and debit card transaction fees totaled $6.7 million while related network costs totaled $3.0 million. On a net basis, we reported $3.8 million as interchange and debit card transaction fees. See note 2 on page 6 of this release and our forthcoming Form 10-K for more information on the effects of this and other accounting changes.

The Cullen/Frost board declared a first-quarter cash dividend of $0.67 per common share, payable March 15, 2019 to shareholders of record on February 28 of this year. The board of directors also declared a cash dividend of $0.3359375 per share of the Noncumulative Perpetual Preferred Stock, Series A, which is traded on the NYSE under the symbol "CFR PrA." The Series A Preferred Stock dividend is also payable on March 15, 2019, to shareholders of record on February 28 of this year.

Cullen/Frost Bankers, Inc. will host a conference call on Thursday, January 31, 2019, at 10 a.m. Central Time (CT) to discuss the results for the quarter and the year. The media and other interested parties are invited to access the call in a “listen only” mode at 800-944-6430.
