CULLEN/FROST REPORTS STRONG FIRST QUARTER RESULTS

• Average loans top $11 billion, increase 15.6 percent

• Average deposits rise 16.6 percent

SAN ANTONIO - Cullen/Frost Bankers, Inc. (NYSE:CFR) today reported strong first quarter 2015 results, including significant growth in net income, loans and deposits.

Cullen/Frost’s net income available to common shareholders for the first quarter of 2015 rose to $70.1 million, an increase of 18.6 percent, or $11.0 million, over first quarter 2014 earnings of $59.2 million. On a per-share basis, net income was $1.10 per diluted common share, compared to $0.96 per diluted common share reported a year earlier. Returns on average assets and common equity were 1.02 percent and 10.34 percent respectively, compared to 1.00 percent and 9.97 percent respectively, for the same period a year earlier.

For the first quarter of 2015, net interest income on a taxable-equivalent basis increased 15.4 percent to $216.7 million, compared to the $187.8 million reported for the same quarter of 2014. Average deposits for the quarter were $23.9 billion, an increase of $3.4 billion, or 16.6 percent, over the $20.5 billion reported for last year's first quarter. Average loans for the first quarter of 2015 increased $1.5 billion, or 15.6 percent, to $11.1 billion, from the $9.6 billion reported for the first quarter a year earlier.

Cullen/Frost acquired WNB Bancshares, Inc., with loans of $670.6 million and deposits of $1.6 billion, on May 30, 2014. These loans and deposits, and the results of operations, are included in quarterly comparisons from date of acquisition.

“I am very pleased to report another great quarter, with positive results in all areas of the company," said Cullen/Frost CEO Dick Evans. "We saw strong growth in loans, deposits and revenues.

“Even with a competitive lending environment and the energy sector slowdown in Texas, we recorded solid increases in average loans and deposits," Evans said. “Our calling effort and team-selling approach allowed us to expand our customer base during the economic downturn, and we are now seeing the results of that hard work. Our credit quality remains good, and we saw a 49 percent decline in net charge-offs from the first quarter last year. In this low oil price environment, we continue to stay in close contact with our energy clients.

“Since 2007, before the financial crisis began, year-to-date average deposits at Frost have risen $13.7 billion, or more than 130 percent. This reflects not only the confidence our customers have in Frost's safety and soundness, but also our efforts to build and expand relationships with customers who understand and appreciate our value proposition.

"Our outstanding service culture once again gained attention and recognition. In February, Frost received 21 national and regional Greenwich Excellence awards for satisfaction in small-business and middle-market banking and treasury management. These awards reflect positive comments from our customers, which is always gratifying.

“Operating in Texas remains a strategic advantage for Frost. With the state's resilient and diversified economy, its business-friendly environment and low taxes, Texas is an economic engine for the nation. Even with the anticipated impact of lower oil prices, Texas will have job growth in 2015. Texas unemployment has been below the U.S. for 98 consecutive months. The robust Texas markets we serve are among the strongest in the country and are regularly noted as top cities for business and good jobs," said Evans.

“Capital levels are strong, and we have plenty of liquidity to fund loans. We have consistently paid a shareholder dividend and have increased the dividend annually for the past 21 years.

"Construction on a new operations center, One Frost, has been under way for more than a year on land we own next to the Frost Technology Center in San Antonio, and several hundred employees have already moved into the first building. When the two-building campus is completed this summer, virtually all of our operations support staff will be together in one facility. This move will create more opportunities for collaboration and innovation and will give our employees a great work environment to better serve our customers.

“I am grateful to our outstanding employees across Texas, who work together to bring the Frost culture to life, take great care of our customers, and help our company grow, succeed and innovate."

Noted financial data for the first quarter of 2015 follows:

• Tier 1 and Total Risk-Based Capital Ratios at the end of the first quarter of 2015 were 12.60 percent and 13.93 percent, respectively, and continue to be in excess of well capitalized levels. The Common Equity Tier 1 ratio was 11.55 percent at March 31, 2015. The tangible common equity ratio was 7.64 percent at the end of the first quarter of 2015, compared to 7.78 percent for the same quarter last year. The tangible common equity ratio, which is a non-GAAP financial measure, is equal to end of period shareholders’ equity less preferred stock, goodwill and intangible assets divided by end-of-period total assets less goodwill and intangible assets. Our current capital ratios exceed Basel III fully-phased in requirements.

• Net-interest income on a taxable equivalent basis for the first quarter of 2015 totaled $216.7 million, an increase of 15.4 percent, compared to $187.8 million for the same period a year ago. Strong growth in deposits has helped to fund the increase in earning assets. The net interest margin was 3.41 percent for the first quarter of 2015, compared to 3.42 percent for the first quarter of 2014, and 3.34 percent for the fourth quarter of 2014. Excess liquidity continues to put pressure on the net interest margin in this low interest rate environment.

• Non-interest income for the first quarter of 2015 totaled $83.2 million, a 7.4 percent increase compared to $77.5 million reported for the first quarter of 2014. Trust and investment management fees were $27.2 million, up $1.8 million, or 6.9 percent, from the first quarter of 2014, with approximately $1.3 million of the increase related to investment fees. Investment management fees are generally assessed based on the market value of trust assets that are managed and held in custody. These investment management fees were favorably impacted by higher market values. Trust and investment management fees also included a $383,000 increase in oil and gas fees. Insurance commissions and fees were $14.6 million, up 11.5 percent, or $1.5 million, compared to the $13.1 million reported in the first quarter a year earlier. Most of this increase was due to higher contingent commission income, up $1.4 million. Other income rose $1.8 million from last year’s first quarter and included increases in income from customer derivative activities, up $1.1 million, and gains on the sale of foreclosed and other assets, up $861,000.

• Non-interest expense was $171.5 million for the quarter, up $13.6 million or 8.6 percent compared to the $157.9 million reported for the first quarter a year earlier. Total salaries rose $5.9 million, or 8.3 percent, to $76.1 million, and were impacted by an increase in the number of employees, including employees from the WNB acquisition, combined with normal annual merit and market increases. Employee benefits were up $2.8 million, or 16.3 percent, and were impacted by the higher number of employees. This increase was also significantly impacted by an increase in expense related to our frozen defined benefit retirement plans, up $1.3 million, which was impacted by lower discount rates and changes to actuarial assumptions. Net occupancy expense rose $2.1 million, or 16.4 percent, resulting primarily from higher lease expense, up $1.1 million, combined with property taxes, up $409,000. Furniture and equipment was up $581,000 or 3.9 percent, due mainly to an $828,000 increase in software maintenance. Other expense was $40.1 million, up 3.8 percent, or $1.5 million, from $38.6 million for the first quarter last year. The first quarter of 2014 included acquisition-related expenses of $1.1 million. Excluding this $1.1 million in acquisition-related expenses, other expense increased $2.6 million or 7.0 percent, and was partly related to check card expense, up $792,000, professional services expense, up $676,000, and sundry and other miscellaneous expenses, up $659,000.

• For the first quarter of 2015, the provision for loan losses was $8.2 million, compared to net charge-offs of $2.0 million. For the first quarter of 2014, the provision for loan losses was $6.6 million, compared to net charge-offs of $3.9 million. The allowance for loan losses as a percentage of total loans was 0.94 percent at March 31, 2015, compared to .98 percent at the end of the first quarter 2014. Non-performing assets were $59.6 million at the end of the first quarter 2015, compared to $61.3 million at the end of the first quarter of 2014 and $65.2 million for the fourth quarter of 2014.
