UMB Financial Corporation Reports First Quarter 2013 Earnings of $34.9 million, or $0.88 per Share

KANSAS CITY, Mo. (April 23, 2013) – UMB Financial Corporation (Nasdaq: UMBF), a diversified financial holding company, announced earnings for the three months ended March 31, 2013 of $34.9 million or $0.88 per share ($0.87 diluted). This is a decrease of $11.4 million, or 24.6 percent, compared to first quarter 2012 earnings of $46.4 million or $1.16 per share ($1.15 diluted).

“This year marks our 100th anniversary and while the operating environment continues to be a challenge, I could not be more pleased that UMB has stood the test of time as a diversified financial services company,” said Mariner Kemper, Chairman and Chief Executive Officer. “Earnings for the first quarter of this year declined compared to the results from the same period a year ago; however, there were two revenue items recognized in the first quarter 2012 worth examining to fully explain the difference. We recognized $5.9 million in gains on the sale of securities available for sale this quarter compared to $16.5 million in the first quarter 2012. Also in the first quarter of 2012, we recognized an $8.2 million adjustment in contingent consideration liabilities due to adoption of new accounting guidance. With these items in mind we have started the year with positive overall results, led by strong performance in our fee businesses. This quarter marks the company’s fifth consecutive quarter of growth in trust and securities processing revenue, which increased 13.9 percent compared to the same period last year to reach a record $62.3 million. On the balance sheet, average loans grew 15.1 percent and marked our twelfth consecutive quarter of loan growth which resulted in stable net interest income. Compared to the industry, the more than 1,400 regulated depositories that had announced first quarter results as of April 22 reported a median increase in loan balances of just 1.3 percent. We achieved this growth with a continued focus on solid credit metrics and sound underwriting practices, which we believe sets us apart from the competition.”

Net Interest Income and Margin

Net interest income for the first quarter of 2013 increased $0.4 million, or 0.5 percent, compared to the same period in 2012. Average earning assets increased by $1.5 billion, or 11.9 percent, compared to the first quarter of 2012. This increase was due to a $764.8 million, or 12.4 percent, increase in average total securities, including trading securities and a $762.2 million, or 15.1 percent, increase in average loans offset by a $70.1 million decrease in average interest bearing due from banks. Net interest margin decreased 24 basis points to 2.51 percent for the three months ended March 31, 2013, compared to the same quarter in 2012.

Noninterest Income and Expense

Noninterest income decreased $11.3 million, or 8.5 percent, for the three months ended March 31, 2013, compared to the same period in 2012. Gains of $5.9 million on securities available for sale were recognized in the first quarter of 2013 compared to $16.5 million during the same period in 2012. Other noninterest income decreased $9.3 million, or 70.7 percent, primarily driven by an $8.2 million adjustment in contingent consideration liabilities on acquisitions recognized in 2012. These adjustments were due to the adoption of new accounting guidance in 2012 related to fair value measurements. These decreases are offset by increased trust and securities processing income of $7.6 million, or 13.9 percent, for the three months ended March 31, 2013, compared to the same period in 2012. The increase in trust and securities processing income was primarily due to a $4.8 million, or 29.8 percent, increase in advisory fee income from the Scout Funds; a $0.8 million, or 4.0 percent, increase in fund administration and custody services; and a $2.1 million, or 11.9 percent, increase in fees related to institutional and personal investment management services.

Noninterest expense increased $8.5 million, or 6.0 percent, for the three months ended March 31, 2013, compared to the same period in 2012. This increase is driven by higher salary and benefits expense of $3.8 million, or 4.7 percent. This increase is due to increases in salaries and wages of $2.0 million, or 4.3 percent, a $0.7 million, or 4.6 percent, increase in commissions and bonuses, and a $1.0 million, or 6.3 percent, increase in employee benefits expense. Other expense increased $2.6 million, or 43.9 percent, primarily due to fair value adjustments to the contingent consideration liabilities on acquisitions. In the first quarter of 2013, these adjustments totaled $3.3 million compared to $1.2 million for the same period in 2012.

“Strong fee business performance continued this quarter, and noninterest income now accounts for 60.4 percent of our total revenue,” said Peter deSilva, President and Chief Operating Officer. “Scout Investments experienced record net flows of $1.6 billion for an overall flow rate of 6.1 percent for the quarter, bringing total Scout assets under management to $25.7 billion. In our Payment Solutions segment, total debit and credit card purchase volume increased by 13.2 percent to $1.8 billion. Healthcare Services surpassed $600 million in Health Savings Account balances, a 47 percent increase over the first quarter of 2012, while spending on healthcare debit cards increased by nearly 30 percent to $881 million. Fund Services closed the quarter with $165.4 billion in assets under administration. We are pleased that these businesses have performed so well. They are an important part of our strategy to offset margin compression and differentiate us from our peers and the competition.”

Balance Sheet

Average total assets for the three months ended March 31, 2013 were $14.8 billion compared to $13.3 billion for the same period in 2012, an increase of $1.5 billion, or 11.2 percent. Average earning assets increased by $1.5 billion for the period, or 11.9 percent.

Average loan balances for the three months ended March 31, 2013 increased $762.2 million, or 15.1 percent, to $5.8 billion compared to the same period in 2012. Actual loan balances on March 31, 2013 were $6.0 billion, an increase of $865.9 million, or 16.8 percent, compared to March 31, 2012. This increase was primarily driven by an increase in commercial loans of $710.6 million, or 28.7 percent.

Nonperforming loans increased to $27.6 million on March 31, 2013 from $25.7 million on March 31, 2012. As a percentage of loans, nonperforming loans decreased to 0.46 percent as of March 31, 2013, compared to 0.50 percent on March 31, 2012. Nonperforming loans are defined as nonaccrual loans and restructured loans. The company’s allowance for loan losses totaled $69.9 million, or 1.16

percent of loans, as of March 31, 2013, compared to $73.5 million, or 1.43 percent of loans, as of March 31, 2012.

Also, as of March 31, 2013, noninterest-bearing demand deposits were 44.6 percent of total deposits.

“We are very pleased to maintain flat net interest income at a time when low rates persist and margin compression plagues the industry. During the quarter, we experienced an 11.9 percent increase in average earning assets due to nearly equal growth in our investment and loan portfolios,” said Mike Hagedorn, Chief Financial Officer. “While volume helps offset the reduction in net interest income, we’re not content with earning asset growth alone. We’re focused on shifting the earning asset mix to further alleviate the effect of margin compression. Since we expect the challenging low interest rate environment to continue, we remain focused on two important objectives: a balanced approach to optimize current net interest income and a nimble position to improve overall earning asset yield when interest rates rise.”

As of March 31, 2013, UMB had total shareholders’ equity of $1.3 billion, an increase of 6.0 percent as compared to the same period in 2012.
