“Results for the fourth quarter 2017 were driven by loan growth, fueled by CRE and construction lending, strong credit metrics and continued growth in net interest margin,” said Mariner Kemper, chairman and chief executive officer. “For the full year, we earned a record $183.0 million, or $3.67 per diluted share, an increase of 19.1 percent compared to $153.6 million or $3.12 per diluted share in 2016. These results were driven by a 12.8 percent year-over-year increase in net interest income with continued favorable pricing and increased loan balances. In 2017, average loan balances increased 8.5 percent and stood at $10.8 billion.”

Net interest income

• On a linked quarter basis, the increase in net interest income was driven by both a 2.1 percent increase in average earning assets and a five basis point improvement in net interest margin.

• Earning asset yields improved four basis points from the linked quarter driven by improved loan yields of seven basis points to 4.40 percent, in part driven by favorablere-pricing and volume changes within the loan portfolio. The cost of interest-bearing liabilities remained flat at 55 basis points while the mix changed from a decrease in federal funds borrowings and an increase in interest-bearing deposits.

• On a year-over-year basis, the increase in net interest income was driven by a 7.1 percent or $738.7 million increase in average loans as well as higher average loan yields, which increased 44 basis points from one year ago, primarily driven by higher interest rates and mix changes.

• For the fourth quarter 2017, average earning assets stood at $19.3 billion, which is an increase of 4.2 percent over the fourth quarter 2016.

Noninterest income

• Fourth quarter 2017 noninterest income increased $1.7 million, or 1.7 percent, on a linked quarter basis largely due to:

• an increase of $3.1 million in other noninterest income primarily due to an increase in company-owned and bank-owned life insurance income;

• a $0.9 million increase in equity earnings on alternative investments;

• which were partially offset by a $2.3 million decrease in gains on sales ofavailable-for-sale securities.

• Noninterest income in the fourth quarter of 2017 improved $7.8 million, or 7.9 percent, compared to the same quarter in 2016 primarily driven by:

• a $3.2 million increase in other noninterest income primarily due to increases in company-owned and bank-owned life insurance income.

• a $1.0 million increase in wealth management revenue, a $0.5 million increase in fund servicing revenue, and a $0.5 million increase in corporate trust revenue all recorded in trust and securities processing;

• a $1.5 million increase in bankcard fees primarily due to increased interchange income; and

• an increase of $1.5 million in brokerage fee income primarily driven by higher12b-1 income.

Total noninterest expense	$	182,559	$	171,821	$	167,847	$	10,738		$	14,712

• GAAP noninterest expense for the fourth quarter of 2017 was $182.6 million and increased $10.7 million, or 6.2 percent from the linked quarter.

• On anon-GAAP basis, operating noninterest expense (as reconciled later in this release) was $182.3 million for the fourth quarter 2017, an increase of $10.5 million, or 6.1 percent, compared to the linked quarter, and an increase of $15.4 million, or 9.2 percent, compared to the fourth quarter 2016.

• The linked quarter increase in operating noninterest expense was driven by:

• a $7.8 million increase in salaries and employee benefits expense primarily driven by a $5.4 million increase in bonus and commission expense, and a $2.0 million increase in employee benefits partially due to increased incentive compensation and profit sharing expense from improved company performance;

• an increase of $1.5 million in marketing and business development related to timing of multiple projects; and

• a $1.0 million increase in other noninterest expense driven by a $1.0 million contribution made to the UMB Financial Corporation Charitable Foundation.

• The year-over-year increase in operating noninterest expense of $15.4 million, or 9.2 percent, was primarily driven by:

• an $11.1 million increase in salaries and benefits expense driven by a $4.2 million increase in bonus and commissions expense, an increase of $2.8 million in salary and wage expense, and an increase of $4.0 million in other employee benefits. These increases were primarily driven by improved company performance during 2017;

• higher processing expenses related to investments for regulatory requirements, cyber security, and the ongoing modernization of the company’s core systems; and

• increased charitable contributions and derivative expense, both recorded in other noninterest expense.

Full Year 2017 Financial Discussion

• The 12.8 percent year-over-year increase in net interest income was driven by benefits from higher short-term interest rates, favorable pricing and increased loan balances. In 2017, average loan balances increased $850.8 million and average loan yields increased 38 basis points. Average interest-bearing liabilities increased $649.9 million, while cost of funds increased 24 basis points.

• Full year noninterest income increased $21.1 million, or 5.2 percent, due to:

• a $5.3 million increase in wealth management revenue, a $3.3 million increase in fund servicing revenue, and a $1.8 million increase in corporate trust revenue all recorded in trust and securities processing;

• a $6.7 million increase in company-owned and bank-owned life insurance income recorded in other noninterest income;

• a $5.4 million increase in brokerage fees, primarily driven by higher12b-1 income;

• a $5.0 million increase in credit card interchange income recorded in bankcard fees;

• partially offset by a $4.3 million decrease in gains on sales ofavailable-for-sale securities and a $3.8 million decrease in equity earnings on alternative investments.

• Full year noninterest expense increased $38.4 million, or 5.8 percent, primarily due to increases in salary and employee benefit expense of $23.8 million due to improved company performance, processing fees of $6.3 million, and equipment expense of $5.7 million.

• On anon-GAAP basis, operating noninterest expense, which excludes the impact of acquisition expenses and other items as reconciled later in this release, was $704.0 million for full-year 2017, an increase of $44.5 million, or 6.8 percent, compared to the full-year 2016.

Income Taxes

• For the year ended December 31, 2017, the company’s effective tax rate remained flat at 22.6 percent as compared to the same period a year earlier.

On December 22, 2017 the Tax Cuts and Jobs Act was signed into law. The new legislation includes numerous changes to existing federal income tax laws and regulations, including a permanent reduction in the federal corporate income tax rate to 21 percent effective January 1, 2018. As a result of the Tax Cuts and Jobs Act, the company was required to revalue its deferred taxes.

Based on currently available information, the company recorded additional income tax expense of $3.0 million during the fourth quarter of 2017 resulting from the Tax Cuts and Jobs Act. The company’s revaluation of its deferred taxes may be subject to further refinement as additional information becomes available and further analysis is completed.

Balance Sheet

• Average total assets for the fourth quarter 2017 were $20.7 billion, an increase of $410.5 million from the linked quarter, and up from $19.9 billion for the same period in 2016.

Non-GAAP Financial Information

In this release, we provide information about net operating income, operating earnings per share—diluted (operating EPS), operating return on average equity (operating ROE), operating return on average assets (operating ROA), operating noninterest expense, operating efficiency ratio, net income from discontinued operations-general operations, and earnings per share from discontinued operations-general operations, all of which arenon-GAAP financial measures. This information supplements the results that are reported according to generally accepted accounting principles in the United States (GAAP) and should not be viewed in isolation from, or as a substitute for, GAAP results. The differences between thenon-GAAP financial measures—net operating income, operating EPS, operating ROE, operating ROA, operating noninterest expense, operating efficiency ratio, net income from discontinued operations-general operations, and earnings per share from discontinued operations-general operations—and the nearest comparable GAAP financial measures are reconciled

later in this release. The company believes that thesenon-GAAP financial measures and the reconciliations may be useful to investors because they adjust for fair value adjustments, acquisition-and severance-related items,one-time marketing agent termination costs, and divestiture costs that management does not believe reflect the company’s fundamental operating performance.

Net operating income for the relevant period is defined as GAAP net income, adjusted to reflect the impact of excluding the following: (i) fair value adjustments on contingent consideration for the acquisitions of Reams Asset Management Company (Reams), (ii) expenses related to acquisitions and divestitures,(iii) non-acquisition related severance expense, and (v) the cumulative tax impact of the previous adjustments. The company believes that the financial impact of excludingnon-acquisition related severance expense will be immaterial in the near future. It is excluded from certain GAAP financial measures as it has an unusually large impact on the company’s financial statements.

Operating EPS (diluted) is calculated as earnings per share as reported, adjusted to reflect, on a per share basis, the impact of excluding thenon-GAAP adjustments described in clauses (i)-(v) above for the relevant period. Operating ROE is calculated as net operating income, divided by the company’s average total shareholders’ equity for the relevant period. Operating ROA is calculated as net operating income, divided by the company’s average assets for the relevant period. Operating noninterest expense for the relevant period is defined as GAAP noninterest expense, adjusted to reflect thepre-tax impact ofnon-GAAP adjustments described in clauses (i)-(iii) above. Operating efficiency ratio is calculated as the company’s operating noninterest expense, net of amortization of other intangibles, divided by the company’s total revenue (calculated as tax equivalent net interest income, plus noninterest income, less gains on sales of securities available for sale, net).

Net income from discontinued operations-general operations for the relevant period is defined as GAAP income from discontinued operations, adjusted to reflect the impact of excludingnon-GAAP adjustments (iii) and (v) above, and (iv) divestiture expenses related to Scout, (vii) the gain on sale of Scout, and (viii) expenses related to thebuy-out and termination of certain marketing and referral agreements in Scout’s business. The company believes that the financial impact of excludingnon-acquisition related severance expense will be immaterial in the near future. It is excluded from certain GAAP financial measures as it has an unusually large impact on the company’s financial statements.

Earnings per share from discontinued operations-general operations (diluted) is calculated as earnings per share from discontinued operations (diluted) as reported, adjusted to reflect, on a per share basis, the impact of excludingnon-GAAP adjustment (iii)-(v), and (vii)-(viii) above for the relevant period.
