     UMB Financial Corporation Reports Second Quarter 2012 Earnings of $29.2 Million, an Increase of 10.8 Percent, and Double-Digit Loan Growth

Kansas City, Mo. (July 24, 2012) – UMB Financial Corporation (NASDAQ: UMBF), a diversified financial holding company, announced earnings for the three months ended June 30, 2012 of $29.2 million or $0.73 per share ($0.72 diluted). This is an increase of $2.8 million, or 10.8 percent, compared to second quarter 2011 earnings of $26.3 million or $0.66 per share ($0.65 diluted). Earnings for the six months ended June 30, 2012 were $75.5 million or $1.89 per share ($1.87 diluted). This is an increase of $18.3 million, or 32.1 percent, compared to the prior year-to-date earnings of $57.2 million or $1.43 per share ($1.42 diluted).

“We are very pleased with our second quarter operating results as they demonstrate growth, discipline and quality,” said Mariner Kemper, Chairman and Chief Executive Officer. “We experienced double-digit loan growth of 10.4 percent. This is our ninth consecutive quarter growing loans, and compares favorably to the industry, which, through July 20, had reported an average increase in loan balances of just 1.7 percent for the second quarter. Net charge offs for the quarter were 0.41 percent, compared to the industry average of 0.63 percent in the first quarter. Noninterest income increased 2.2 percent over the second quarter of 2011 and represents 57.8 percent of total revenue, providing the company with a unique position in the marketplace. Finally, expenses were flat for the quarter.”

Net interest income for the second quarter of 2012 increased $0.5 million, or 0.6 percent, compared to the same period in 2011. Average earning assets increased by $839.3 million, or 7.4 percent, compared to the second quarter of 2011. This increase was due to a $778.2 million, or 13.6 percent, increase in average total securities, including trading securities and a $492.8 million, or 10.4 percent, increase in average loans offset by a $440.3 million decrease in average interest bearing due from banks. Net interest margin decreased 16 basis points to 2.82 percent for the three months ended June 30, 2012 compared to the same quarter in 2011.

Noninterest Income and Expense

Noninterest income increased $2.4 million, or 2.2 percent, for the three months ended June 30, 2012 compared to the same period in 2011. This increase is partially attributed to increased trust and securities processing income of $2.1 million, or 4.0 percent, for the three months ended June 30, 2012 compared to the same period in 2011. The increase in trust and securities processing income was primarily due to a $1.2 million, or 7.1 percent, in advisory fee income from the Scout Funds, a $0.5 million, or 2.9 percent, increase in fund administration and custody services and a $0.6 million, or 3.5 percent, increase in fees related to institutional and personal investment management services.

Noninterest expense decreased $0.9 million, or 0.6 percent, for the three months ended June 30, 2012 compared to the same period in 2011. This decrease is driven by the impact from the legal settlement in 2011, mostly offset by higher salary and benefits expense in 2012 of $5.1 million, or 7.0 percent. The higher salaries and benefits is due to increases in salaries and wages of $3.6 million, or 7.8 percent, and a $1.4 million, or 13.4 percent, increase in employee benefits expense. During the second quarter of 2011, the company and its subsidiary banks entered into an agreement to settle a class action lawsuit and established a $7.8 million escrow fund in accordance with the agreement.

“Our diversified fee businesses continue to perform well, contributing to our results in the second quarter,” said Peter deSilva, President and Chief Operating Officer. “Our Payment Solutions segment posted record purchase volume as spending across our entire suite of card products expanded by 29.8 percent versus the second quarter of 2011. Spending on healthcare cards grew 16.3 percent, which drove a 25 percent growth in healthcare interchange as compared to the prior year. Institutional Investment Management, which is our Scout Investments business, continues to execute on its distribution strategy. Net fund flows for the quarter were $13.3 million, bringing year-to-date flows to more than $1.5 billion. Scout assets under management stood at $22.4 billion at June 30. Our wealth management platform for individuals ended the quarter with assets under management of nearly $8.6 billion, which when combined with Scout, brought total company assets under management to $31 billion at the end of the quarter, an increase of 6.8 percent compared to the second quarter of 2011.”

Balance Sheet

Average total assets for the three months ended June 30, 2012 were $13.2 billion compared to $12.4 billion for the same period in 2011, an increase of $838.7 million, or 6.8 percent. Average earning assets increased by $839.3 million for the period, or 7.4 percent.

Average loan balances for the three months ended June 30, 2012 increased $492.8 million, or 10.4 percent, to $5.2 billion compared to the same period in 2011. Actual loan balances on June 30, 2012 were $5.3 billion, an increase of $584.3 million, or 12.4 percent, compared to June 30, 2011. This increase was primarily driven by an increase in commercial loans of $623.0 million, or 31.0 percent.

Nonperforming loans increased to $30.6 million on June 30, 2012 from $15.4 million on June 30, 2011. As a percentage of loans, nonperforming loans increased to 0.58 percent as of June 30,

2012 compared to 0.33 percent on June 30, 2011. Nonperforming loans are defined as nonaccrual loans and restructured loans. The company’s allowance for loan losses totaled $72.7 million, or 1.37 percent of loans, as of June 30, 2012 compared to $72.4 million, or 1.53 percent of loans, as of June 30, 2011.

For the three months ended June 30, 2012, average securities, including trading securities, totaled $6.5 billion. This is an increase of $778.2 million, or 13.6 percent, from the same period in 2011.

Average total deposits increased $801.4 million, or 8.4 percent, to $10.3 billion for the three months ended June 30, 2012 compared to the same period in 2011. Average noninterest-bearing demand deposits increased $915.1 million, or 28.5 percent, compared to 2011. Average interest-bearing deposits decreased by $113.7 million, or 1.8 percent, in 2012 as compared to 2011.

Also, as of June 30, 2012, noninterest-bearing demand deposits were 40.8 percent of total deposits.

“We continue to see strong growth in average deposits, which increased 8.4 percent during the quarter,” said Mike Hagedorn, Chief Financial Officer. “While this validates the strength and stability of our balance sheet, it does put downward pressure on net interest margin. The quality of our investment portfolio allowed us to harvest $3.2 million in pre-tax gains on the sale of securities during the quarter and $19.8 million year-to-date, supplementing our revenue in a difficult rate environment. In addition, shareholder equity has increased by 40.6 percent since the beginning of 2008, demonstrating our ability to grow equity through the financial crisis without assistance from the government.”

As of June 30, 2012, UMB had total shareholders’ equity of $1.3 billion, an increase of 10.5 percent as compared to the same period in 2011.
