UMB Financial Corporation Reports Second Quarter 2013 Earnings of $29.9 million, $0.74 per Diluted Share

KANSAS CITY, Mo. (July 23, 2013) – UMB Financial Corporation (NASDAQ: UMBF), a diversified financial holding company, announced earnings for the three months ended June 30, 2013 of $29.9 million or $0.75 per share ($0.74 diluted). This is an increase of $0.8 million, or 2.6 percent, compared to second quarter 2012 earnings of $29.2 million or $0.73 per share ($0.72 diluted). Earnings for the six months ended June 30, 2013 were $64.9 million or $1.62 per share ($1.61 diluted). This is a decrease of $10.7 million, or 14.1 percent, compared to the prior year-to-date earnings of $75.5 million or $1.89 per share ($1.87 diluted).

“We are pleased to report that actual period-end loan balances increased 19.5 percent year-over-year, representing our thirteenth consecutive quarter of loan growth. This demonstrates our commitment to serving the needs of our customers and partnering with our communities,” said Mariner Kemper, Chairman and Chief Executive Officer. “For comparison, the more than 1,500 depositories that have announced results as of July 22 reported median loan growth of just 1.4 percent. In addition, trust and securities processing revenue increased 13.9 percent compared to the same period in the prior year and noninterest expense was $150.3 million, an increase of under four percent compared to the same period a year ago, evidence that our focus on expense control is paying off.”

Net Interest Income and Margin

Net interest income for the second quarter of 2013 increased $2.0 million, or 2.4 percent, compared to the same period in 2012. Average earning assets increased by $1.6 billion, or 13.2 percent, compared to the second quarter of 2013. This increase was due to a $661.2 million, or 10.2 percent, increase in average total securities, including trading securities and a $942.3 million, or 18.1 percent, increase in average loans. Net interest margin decreased 26 basis points to 2.56 percent for the three months ended June 30, 2013, compared to the same quarter in 2012.

Noninterest Income and Expense

Noninterest income increased $3.4 million, or 3.0 percent, for the three months ended June 30, 2013, compared to the same period in 2012. This increase is primarily attributed to increased trust and

securities processing income of $7.7 million, or 13.9 percent, for the three months ended June 30, 2013 compared to the same period in 2012. The increase in trust and securities processing income was primarily due to a $4.2 million, or 23.7 percent increase, in advisory fee income from the Scout Funds and a $2.4 million, or 13.9 percent, increase in fees related to institutional and personal investment management services. Gains of $1.5 million on securities available for sale were recognized in the second quarter of 2013 compared to $3.2 million during the same period in 2012. Other noninterest income decreased $2.5 million, or 54.4 percent, primarily driven by decreased fair value adjustments on interest rate swap transactions of $1.9 million compared to the same period in 2012.

Noninterest expense increased $5.6 million, or 3.9 percent, for the three months ended June 30, 2013, compared to the same period in 2012. This increase is driven by higher salary and benefits expense of $5.6 million, or 7.1 percent. This increase is due to increases in salaries and wages of $2.6 million, or 5.2 percent, a $1.7 million, or 10.6 percent, increase in commissions and bonuses, and a $1.3 million, or 10.6 percent, increase in employee benefits expense. Processing fees increased $1.7 million, or 13.5 percent, due primarily to fees paid by the advisor to third-party distributors of the Scout Funds. These increases were offset by a decrease in other expense of $3.1 million, or 39.3 percent, primarily due to decreased fair value adjustments on interest rate swap transactions of $1.9 million.

“Once again, our fee businesses posted strong quarterly results and noninterest income represented 58 percent of our total revenue,” said Peter deSilva, President and Chief Operating Officer. “Net inflows in our Institutional Investment Management segment were $902 million, propelling Scout assets under management to $26.3 billion at quarter end, an increase of 17.5 percent compared to a year ago. Our wealth management platform for individuals ended the quarter with assets under management of $10.3 billion, which when combined with Scout, brought total company assets under management to $36.6 billion at the end of the quarter, an increase of 18.3 percent compared second quarter 2012. Our Asset Servicing business has added $20.7 billion in assets under administration during the past year, and finally, in our Payment Solutions segment, total quarterly debit and credit card purchase volume increased by 16.5 percent to $1.7 billion.”

Balance Sheet

Average total assets for the three months ended June 30, 2013 were $14.9 billion compared to $13.2 billion for the same period in 2012, an increase of $1.7 billion, or 12.7 percent. Average earning assets increased by $1.6 billion for the period, or 13.2 percent.

Average loan balances for the three months ended June 30, 2013 increased $942.3 million, or 18.1 percent, to $6.2 billion compared to the same period in 2012. Actual loan balances on June 30, 2013 were $6.3 billion, an increase of $1.0 billion, or 19.3 percent, compared to June 30, 2012. This increase was primarily driven by an increase in commercial loans of $695.8 million, or 26.4 percent, and a $216.8 million, or 16.0 percent, increase in commercial real estate loans. Nonperforming loans decreased to $25.5 million on June 30, 2013 from $30.6 million on June 30, 2012. As a percentage of loans, nonperforming loans decreased to 0.40 percent as of June 30, 2013, compared to 0.58 percent on June 30, 2012. Nonperforming loans are defined as nonaccrual loans and restructured loans. The company’s allowance for loan losses totaled $71.6 million, or 1.13 percent of loans, as of June 30, 2013, compared to $72.7 million, or 1.37 percent of loans, as of June 30, 2012.

For the three months ended June 30, 2013, average securities, including trading securities, totaled $7.2 billion. This is an increase of $661.2 million, or 10.2 percent, from the same period in 2012.

Average total deposits increased $1.3 billion, or 12.2 percent, to $11.6 billion for the three months ended June 30, 2013, compared to the same period in 2012. Average noninterest-bearing demand deposits increased $510.1 million, or 12.4 percent, compared to 2012. Average interest-bearing

deposits increased by $749.3 million, or 12.1 percent, in 2013 as compared to 2012. Total deposits as of June 30, 2013 were $11.7 billion, compared to $10.3 billion as of June 30, 2012, a 13.6 percent

increase. Also, as of June 30, 2013, noninterest-bearing demand deposits were 41.7 percent of total deposits.

“Growth in earning assets and improved pricing on deposits drove a modest lift in our net interest income for the second quarter,” said Mike Hagedorn, Chief Financial Officer. “Loan growth represented nearly sixty percent of the year-over-year increase in average earnings assets and we expect the shift in earning asset mix to continue. However, without an increase in the Federal Funds rate, our loan yields, which are largely tied to indices, will remain under pressure.”

As of June 30, 2013, UMB had total shareholders’ equity of $1.2 billion, which is flat as compared to the same period in 2012.

Year-to-Date

Earnings for the six months ended June 30, 2013 were $64.9 million or $1.62 per share ($1.61 diluted). This is a decrease of $10.7 million, or 14.1 percent, compared to the prior year-to-date earnings of $75.5 million or $1.89 per share ($1.87 diluted).

Other noninterest income decreased $11.8 million, or 66.5 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 and changes in cash flow projections. These decreases are offset by increased trust and securities processing income of $15.3 million, or 13.9 percent, for the six months ended June 30, 2013, compared to the same period in 2012. The increase in trust and securities processing income was primarily due to a $9.0 million, or 26.6 percent, increase in advisory fee income from the Scout Funds; a $1.3 million, or 3.4 percent, increase in fund administration and custody services; and a $4.5 million, or 12.9 percent, increase in fees related to institutional and personal investment management services.

Noninterest expense increased $14.1 million, or 4.9 percent, for the six months ended June 30, 2013 compared to the same period in 2012. This increase is primarily driven by an increase in salary and employee benefit expense of $9.4 million, or 5.9 percent, and a $3.0 million, or 11.7 percent, increase in processing fees primarily driven by fees paid by the advisor to third-party distributors of the Scout Funds.
