MB FINANCIAL, INC. REPORTS THIRD QUARTER 2017NET INCOME OF $60.8 MILLION

CHICAGO, October 19, 2017 – MB Financial, Inc. (NASDAQ: MBFI), the holding company for MB Financial Bank, N.A., today announced third quarter 2017 net income of $60.8 million compared to $44.5 million last quarter and $44.4 million in the third quarter a year ago.  Diluted earnings per common share were $0.69 in the third quarter of 2017 compared to $0.50 last quarter and $0.54 in the third quarter a year ago.  

"Our record quarter is directly related to executing our long-term strategy," stated Mitchell Feiger, President and Chief Executive Officer of MB Financial, Inc. "We are intent on building a bank with superior returns and lower risk. Our results this quarter show our progress with solid performance across all business units. We believe our strategic combination of high quality low-cost deposits; strong and rapidly growing fee businesses; revenue, profit, loan, and deposit diversification; and close attention to credit quality will lead to peer-leading performance."

Mr. Feiger continued, "Our operating earnings increased by 31.5% to $62.8 million, this quarter, which is an all-time record. This can be attributed to several factors including an increase in net interest income, decreased provision for credit losses, increased lease financing revenues, controlled expenses and certain tax benefits. In addition, annualized loan growth was 8.5%, on top of the 21.2% recorded last quarter. Further, credit quality remained strong in the third quarter with net recoveries of $0.6 million and non-performing loans down two basis points to 0.36% of total loans."

Key Items (compared to 2Q17)

Operating Earnings

• Operating earnings increased by $15.0 million, or 31.5%, to $62.8 million compared to the prior quarter. This growth resulted from the following items (net of tax): an increase in net interest income of $4.7 million, a decrease in provision for credit losses of $3.1 million, an increase in lease financing revenues of $2.8 million and tax benefits of $4.0 million mostly due to the impact of the rate increase on our Illinois deferred tax assets and a reduction in tax accruals attributable to compensation.

• Diluted operating earnings per common share were $0.72 compared to $0.54 in the prior quarter.

Loans

• Loans, excluding purchased credit-impaired loans, increased $288.4 million (+2.1%, or +8.5% annualized) to $13.8 billion. Growth was driven by increases in commercial and commercial real estate loans.

• Average loan balances, excluding purchased credit-impaired loans, increased $426.2 million due to increases in commercial, commercial real estate and residential real estate loans.

• Average yield on loans, excluding accretion on loans acquired in bank mergers, increased 11 basis points to 4.17% from 4.06% in the prior quarter.

Deposits

• Low-cost deposits declined $66.5 million in the quarter (-0.5%, or -2.2% annualized) to $12.0 billion due to normal fluctuations in balances. Additionally, there was some migration from non-interest bearing to NOW and money market deposits as rates have modestly increased.

• Average low-cost deposits increased $216.7 million.

• Average cost of total deposits increased five basis points to 0.30% due to an unfavorable shift in the mix of deposits.

Net interest margin

• Net interest margin on a fully tax equivalent basis, excluding accretion on loans acquired in bank mergers, increased two basis points in the quarter to 3.56%. This increase was due to higher loan yields partly offset by increased funding costs and an unfavorable shift in the mix of liabilities.

• Average interest earning assets increased $502.3 million due to an increase in loan balances.

• Average cost of funds increased seven basis points to 0.46%.

Operating Segments (compared to 2Q17)

Banking

• Operating earnings were $54.5 million, an increase of $13.3 million, or 32.4%, compared to the prior quarter.

• This increase was due to increased net interest income, lower provision for credit losses and tax benefits mostly due to the impact of the rate increase on our Illinois deferred tax assets and a reduction in tax accruals attributable to compensation.

Leasing

• Operating earnings were $6.0 million, an increase of $1.9 million, or 45.5%, compared to the prior quarter.

• Operating earnings for the quarter increased due to higher lease financing revenues resulting from increased promotional income and fees from the sale of third-party equipment maintenance contracts partially offset by lower residual gains.

Mortgage Banking

• Operating earnings were relatively consistent at $2.2 million compared to $2.4 million in the prior quarter.

Operating Segments

The Company has three reportable operating segments: Banking, Leasing and Mortgage Banking. Our Banking Segment generates revenues primarily from its lending, deposit gathering and fee business activities.

⁽¹⁾  Includes health insurance, payroll taxes, 401(k) and profit sharing contributions, overtime and temporary help expenses.

Banking Segment operating earnings for the third quarter of 2017 increased $13.3 million compared to the prior quarter.

• Net interest income increased due to higher average loan yields and balances partly offset by a higher cost of funds.

• Provision for credit losses decreased due to net recoveries and less loan growth in the quarter.

• Non-interest income increased due to higher capital markets and treasury management fees (mainly swap fees) and stronger earnings from investments in Small Business Investment Companies ("SBICs"). Non-interest expense increased due to higher salaries and employee benefits expense as a result of an additional day in the quarter, annual salary increases for hourly employees, higher temporary help expense and higher 401(k) and profit sharing contributions partly offset by a decrease in bonus expense. Additionally, salaries and employee benefits expense for the prior quarter was impacted by lower health insurance expense.

• Income tax expense includes tax benefits of $4.0 million due to the impact of the Illinois state income tax rate increase on our deferred tax assets as well as a reduction in tax accruals attributable to compensation.

• Total assets increased due to the loan growth in the quarter.

• Excluded from operating earnings for the third quarter of 2017 (and from the table above) were $2.8 million in branch exit and facilities impairment charges from the closing of four branches.

Banking Segment operating earnings for the nine months ended September 30, 2017 grew $34.2 million compared to the same period last year. Our merger with American Chartered Bancorp Inc. in the third quarter of 2016 positively impacted net income and total assets.

Mortgage Banking Segment operating earnings for the third quarter of 2017 decreased $196 thousand compared to the prior quarter.

• Net interest income increased due to earnings on higher average loan balances.

• Mortgage origination revenue decreased as a result of lower origination volume and lower gain on sale margin.

• Salaries and employee benefits expense decreased due to lower commissions and decline in the number of employees partly offset by less deferred origination costs.

Mortgage Banking Segment operating earnings for the nine months ended September 30, 2017 decreased $11.4 million compared to the same period last year.

• Net interest income increased due to earnings on higher average balances of loans held for investment.

• Mortgage origination revenue decreased due to lower mortgage origination volume as a result of higher mortgage interest rates and lower gain on sale margin.

⁽¹⁾  Annualized operating return on average assets is computed by dividing annualized operating earnings by average total assets. Annualized operating return on average common equity is computed by dividing annualized operating earnings by average common equity. Operating earnings is defined as net income as reported less non-core items, net of tax.

⁽²⁾  Annualized cash return on average tangible common equity is computed by dividing net cash flow available to common stockholders (net income available to common stockholders, plus other intangibles amortization expense, net of tax benefit) by average tangible common equity (average common stockholders' equity less average goodwill and average other intangibles, net of tax benefit).

⁽³⁾  Annualized cash operating return on average tangible common equity is computed by dividing annualized cash operating earnings (operating earnings plus other intangibles amortization expense, net of tax benefit, less dividends on preferred shares) by average tangible common equity. Operating earnings is defined as net income as reported less non-core items, net of tax.

⁽⁴⁾  Equals total non-interest expense excluding non-core items divided by the sum of net interest income on a fully tax equivalent basis, total non-interest income less non-core items, and tax equivalent adjustment on the increase in cash surrender value of life insurance.

⁽⁵⁾  Equals total non-interest expense excluding non-core items less total non-interest income excluding non-core items, and including tax equivalent adjustment on the increase in cash surrender value of life insurance divided by average assets.

⁽⁶⁾  Equals total non-interest income excluding non-core items and tax equivalent adjustment on the increase in cash surrender value of life insurance divided by the sum of net interest income on a fully tax equivalent basis, total non-interest income less non-core items, and tax equivalent adjustment on the increase in cash surrender value of life insurance.

⁽⁷⁾  Represents net interest income on a fully tax equivalent basis assuming a 35% tax rate, as a percentage of average interest earning assets.

⁽⁸⁾  Represents net interest income on a fully tax equivalent basis assuming a 35% tax rate, excluding acquisition accounting discount accretion on bank merger loans as a percentage of average interest earning assets.

⁽⁹⁾  Equals total interest expense divided by the sum of average interest bearing liabilities and noninterest bearing deposits.

⁽¹⁰⁾  Non-performing loans excludes purchased credit-impaired loans and loans held for sale.  Non-performing assets excludes purchased credit-impaired loans, loans held for sale, and other real estate owned related to FDIC transactions.

NON-GAAP FINANCIAL INFORMATION

This document contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (GAAP). These measures include operating earnings, core non-interest income, core non-interest income to revenues (with non-core items excluded from both core non-interest income and revenues), core non-interest expense, non-core non-interest income and non-core non-interest expense, net interest income on a fully tax equivalent basis, net interest margin on a fully tax equivalent basis, net interest margin on a fully tax equivalent basis excluding acquisition accounting discount accretion on bank mergers loans, efficiency ratio and the ratio of annualized net non-interest expense to average assets with net gains on investment securities, net gains and losses on disposal of other assets, recovery of low to moderate income real estate investment and increase in market value of assets held in trust for deferred compensation excluded from the non-interest income components of these ratios and branch exit and facilities impairment charges, merger related and repositioning expenses, increase in market value of assets held in trust for deferred compensation and contribution to MB Financial Charitable Foundation excluded from the non-interest expense components of these ratios, with tax equivalent adjustment for tax-exempt interest income and increase in cash surrender value of life insurance, as applicable; ratios of tangible equity to tangible assets, tangible common equity to tangible assets and tangible common equity to risk-weighted assets; tangible book value per common share; annualized operating return on average assets, annualized operating return on average common equity, annualized cash return on average tangible common equity and annualized cash operating return on average tangible common equity. Our management uses these non-GAAP measures, together with the related GAAP measures, in its analysis of our performance and in making business decisions. Management also uses these measures for peer comparisons.

Management believes that operating earnings, core and non-core non-interest income and core and non-core non-interest expense are useful in assessing our core operating performance and in understanding the primary drivers of our non-interest income and non-interest expense when comparing periods.

Management believes that operating earnings adjusted for merger related and repositioning expenses is a useful measure because it excludes expenses that can significantly fluctuate from acquisition to acquisition. In addition, management believes that excluding these expenses provides investors and analysts a measure to better understand the Company's primary operations when comparing the periods presented in the earnings release.

The tax equivalent adjustment to net interest income, net interest margin, tax-exempt interest income and increase in cash surrender value of life insurance recognizes the income tax savings when comparing taxable and tax-exempt assets and assumes a 35% tax rate. Management believes that it is a standard practice in the banking industry to present net interest income and net interest margin on a fully tax equivalent basis, and accordingly believes that providing these measures may be useful for peer comparison purposes. For the same reasons, management believes that the tax equivalent adjustments to tax-exempt interest income and increase in cash surrender value of life insurance are useful.

Management also believes that by excluding net gains on investment securities, net gains and losses on disposal of other assets, recovery of low to moderate income real estate investment and increase in market value of assets held in trust for deferred compensation from the non-interest income components, and excluding branch exit and facilities impairment charges, merger related and repositioning expenses, increase in market value of assets held in trust for deferred compensation and contribution to MB Financial Charitable Foundation from the non-interest expense components, of the efficiency ratio and the ratio of annualized net non-interest expense to average assets, these ratios better reflect our core operating performance, as the excluded items do not pertain to our core business operations and their exclusion makes these ratios more meaningful when comparing our operating results from period to period.

The other measures exclude the acquisition-related goodwill and other intangible assets, net of tax benefit, in determining tangible assets, tangible equity, tangible common equity and average tangible common equity and exclude other intangible amortization expense, net of tax benefit, in determining net cash flow available to common stockholders. Management believes the presentation of these other financial measures, excluding the impact of such items, provides useful supplemental information that is helpful in understanding our financial results, as they provide a method to assess management’s success in utilizing our tangible capital, as well as our capital strength. Management also believes that providing measures that exclude balances of acquisition-related goodwill and other intangible assets, which are subjective components of valuation, facilitates the comparison of our performance with the performance of our peers. In addition, management believes that these are standard financial measures used in the banking industry to evaluate performance.

The non-GAAP disclosures contained herein should not be viewed as substitutes for the results determined to be in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies.

Reconciliations of net interest margin on a fully tax equivalent basis to net interest margin and net interest margin on a fully tax equivalent basis excluding acquisition accounting discount accretion on bank merger loans to net interest margin are contained in the tables under “Net Interest Margin.” A reconciliation of tangible book value per common share to book value per common share is contained in the
