MB FINANCIAL, INC. REPORTS FOURTH QUARTER 2017 NET INCOME OF $144.2 MILLION

CHICAGO, January 25, 2018 – MB Financial, Inc. (NASDAQ: MBFI), the holding company for MB Financial Bank, N.A., today announced fourth quarter 2017 net income of $144.2 million compared to $60.8 million last quarter and $47.2 million in the fourth quarter a year ago.  Diluted earnings per common share were $1.67 in the fourth quarter of 2017 compared to $0.69 last quarter and $0.53 in the fourth quarter a year ago. Annual net income for 2017 was $304.0 million compared to $174.1 million for 2016. Diluted earnings per common share were $3.49 for 2017 compared to $2.13 for 2016.

Fourth quarter 2017 operating earnings were $47.4 million compared to $62.8 million last quarter and $51.8 million in the fourth quarter a year ago.  Diluted operating earnings per common share were $0.53 in the fourth quarter of 2017 compared to $0.72 last quarter and $0.59 in the fourth quarter a year ago. Annual operating earnings for 2017 were $211.1 million compared to $190.5 million for 2016. Diluted operating earnings per common share were $2.39 for 2017 compared to $2.34 for 2016.

Capital Raise and Tax Reform Update

• In November 2017, we successfully issued $200 million in 6% fixed rate non-cumulative perpetual preferred stock, and our bank subsidiary issued $175 million in 4% fixed-to-floating rate subordinated notes. A portion of the net proceeds of the preferred stock offering will be used to redeem all $100 million of our 8% non-cumulative perpetual preferred stock on February 15, 2018 and $10 million was used to pre-pay our term note in January 2018.

• We recognized a $104.2 million tax benefit in the fourth quarter of 2017 due to the enactment of the Tax Cuts and Jobs Act of 2017 ("TCJ Act"). Approximately $6.5 million of the tax benefit was recognized at our Banking Segment, $65.3 million at our Leasing Segment, and $32.4 million at our Mortgage Banking Segment.

• Our company's capital position was strengthened by the capital we raised and the TCJ Act tax benefit. Our tangible common equity to tangible assets increased to 8.70% at December 31, 2017 compared to 8.07% at September 30, 2017 and our total capital to risk-weighted assets increased to 14.23% at December 31, 2017 compared to 11.67% at September 30, 2017.

• In the fourth quarter, we contributed $7.5 million to the MB Financial Charitable Foundation, raised our minimum wage to $15 per hour effective January 2018, and awarded approximately $2.7 million in one-time bonuses.

• We estimate that our effective tax rate in 2018 will be reduced by approximately 10%, due to the TCJ Act, to 24%.

"We had a very busy fourth quarter and 2017.  We raised $375 million of capital; increased our residential mortgage team with members transferred from Busey Bank; and as a result of a Tax Cuts and Jobs Act of 2017 tax benefit, we were able to give back to our employees and communities.  Our capital position meaningfully strengthened. We significantly grew our core banking business.  And, we did so while maintaining high credit quality," said Mitchell Feiger, President and Chief Executive Officer of MB Financial, Inc.  "In 2017, we had solid loan growth of 9.8%, low-cost deposit growth of 3.4%, and key fee growth, excluding mortgage banking revenue, of 15.1%.  I attribute our success to an unwavering focus on the four pillars of our long-term strategy:  high quality low-cost deposits; strong rapidly growing fee businesses; diversification across revenue and profit sources, loans and deposits; and close attention to balance sheet risk, especially credit quality."

Mr. Feiger continued, "Our operating earnings for the quarter were down as funding costs and other expenses increased and our Mortgage Banking segment recorded a loss.  While disappointing, many of the things we accomplished in 2017, particularly in the fourth quarter, set us up well for 2018. We had significant growth in low-cost deposits in the quarter (15.6% annualized) led by growth in noninterest bearing deposits of 18.2% on an annualized basis. Lease finance revenue grew 17.9% in the year as a result of investments we made in Leasing personnel and products. Our Wealth Management Department saw good growth and reorganized to be even more successful. Fourth quarter trust and asset management fees were 6.9% greater than the same period a year earlier. Our Cards and Payments businesses continues to grow at a rapid pace. Fourth quarter cards fees were 15.9% greater than the same period in 2016. MB Business Capital (our asset-based lending unit) and our Commercial Specialty businesses, among others, added significant numbers of new clients in the year. Our investment portfolio again had strong returns. And our growing investments in technology and infrastructure should provide a more reliable, safer, and more nimble operating environment for our company. These investments, new clients, increased revenues, and strong expense control, along with an expected improvement in our net interest margin in the first quarter of 2018 position us well for 2018.”

Key Items - Full Year (compared to 2016)

Operating Earnings

• Operating earnings increased$20.6 million, or 10.8%, to $211.1 million compared to the prior year.

• The Banking Segment contributed $34.1 million to the increase in operating earnings partly offset by a $13.4 million decrease in the Mortgage Banking Segment. Leasing Segment operating earnings were consistent with the prior year.

• Banking Segment operating earnings were positively impacted by strong loan growth, improvements in nearly all key fee initiatives, as well as our merger with American Chartered Bancorp Inc. ("American Chartered") completed in third quarter 2016.

• Mortgage Banking Segment operating earnings, which declined from $18.9 million to $5.5 million, were impacted by lower origination and servicing fees.

• Diluted operating earnings per common share were $2.39 compared to $2.34 in the prior year.

Loans

• Loans, excluding purchased credit-impaired loans, increased$1.2 billion (+9.8%). Growth was driven by increases in commercial, commercial real estate, and residential real estate loan balances.

• Quarterly average loan balances, excluding purchased credit-impaired loans, increased$1.3 billion.

• Our average yield on loans, excluding accretion on loans acquired in bank mergers, was 4.09%, 20 basis points higher than in the prior year. This increase was driven by several Federal Reserve interest rate increases in 2016 and 2017.

Deposits

• Low-cost deposits increased$416.9 million (+3.4%) to $12.5 billion. Growth was driven by a $411.8 million increase in money market and NOW accounts.

• Quarterly average low-cost deposits increased$244.6 million.

• Average cost of total deposits increasedeight basis points to 0.28%.

Net interest margin

• Our net interest margin on a fully tax equivalent basis, excluding accretion on loans acquired in bank mergers, increasedthree basis points to 3.52%. This increase was due to a favorable change in the mix of interest earning assets and higher loan yields partly offset by increased funding costs and an unfavorable shift in the mix of liabilities.

• Average cost of funds increased16 basis points to 0.43%.

2

Key Items - Fourth Quarter (compared to third quarter of 2017)

Operating Earnings

• Operating earnings decreased$15.4 million, or 24.5%, to $47.4 million compared to the prior quarter. This decrease resulted from the following items, net of income taxes:

• a $2.1 million decrease in net interest income due to lower yields on interest earning assets and a higher cost of funds;

• a $3.4 million decrease in mortgage banking revenue due to lower origination and servicing fees;

• a $3.1 million increase in core non-interest expense due to higher occupancy and equipment expense, computer services and telecommunication, professional and legal, and other operating expenses; and

• a $2.1 million increase in state income tax accruals as a result of income allocation to high income tax rate jurisdictions. Prior quarter operating earnings included tax benefits of $4.0 million due to the impact of the Illinois state income tax rate increase and a reduction in tax accruals attributable to compensation.

• The $3.1 million after-tax increase in core non-interest expense includes $511 thousand of after-tax expenses from additional mortgage banking operations acquired in December 2017 (see the "Operating Segments - Mortgage Banking Segment" section for further information). In addition, it includes approximately $1.6 million of after-tax expenses that are not expected to repeat in the first quarter of 2018. See the Non-interest Expense section for further information on the run-rate of non-interest expense.

• Diluted operating earnings per common share were $0.53 compared to $0.72 in the prior quarter.

Loans

• Loans, excluding purchased credit-impaired loans, increased$92.9 million (+0.7%, or +2.7% annualized) to $13.8 billion due to growth in lease loan and commercial real estate loan balances.

• Average loan balances, excluding purchased credit-impaired loans, increased$177.8 million due to an increase in commercial real estate loans.

• Average yield on loans, excluding accretion on loans acquired in bank mergers, was 4.17%, unchanged from the prior quarter.

Deposits

• Low-cost deposits increased$472.6 million in the quarter (+3.9%, or +15.6% annualized) to $12.5 billion. Growth was driven by a $280.4 million increase (+4.6%, or +18.2% annualized) in non-interest bearing deposits as well as a $112.7 million increase (+2.3%, or +9.2% annualized) in money market and NOW accounts.

• Average low-cost deposits increased$295.4 million.

• Average cost of total deposits increasedsix basis points to 0.36% due to increases in interest rates paid on deposits and an unfavorable shift in the mix of deposits. Average low-cost deposits decreased to 83% of total deposits in the fourth quarter 2017 compared to 84% in the prior quarter.

Net interest margin

• Net interest margin on a fully tax equivalent basis, excluding accretion on loans acquired in bank mergers, decreasedseven basis points in the quarter to 3.49%. Approximately three basis points of the decrease was due to the Company maintaining higher interest earning cash balances during the quarter in anticipation of redeeming our 8% non-cumulative perpetual preferred stock and pre-paying our term note. Two basis points of the decrease was due to increased deposit costs and an unfavorable shift in the mix of deposits, and two basis points related to the new subordinated debt issued in November 2017.

• Average cost of funds increasedfive basis points to 0.51%.

• The TCJ Act corporate tax rate, effective in 2018, is expected to decrease our taxable equivalent net interest margin by approximately six basis points.  The expected decrease is caused by a lower tax benefit on municipal securities and tax exempt loans.

Guidance for 2018 on selected financial items:

We expect:

• outstanding loans to grow in the mid to high single digits (percent) for the year.

• net interest margin for the first quarter of 2018, excluding accretion on bank merger loans and inclusive of the six basis point decrease due to the TJC Act, to moderately increase from the fourth quarter of 2017, which was 3.49%.

• non-interest expense, excluding commissions, to grow in the low single digits (percent) from the fourth quarter 2017 run-rate found on page 23.

• annual operating earnings for the Mortgage Banking Segment to be between $8 to $12 million. The first and fourth quarters of the year are typically the slowest for mortgage banking activity.

• our effective tax rate in 2018 to be approximately 24%.

Operating Segments

The Company has three reportable operating segments: Banking, Leasing, and Mortgage Banking.

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

Banking Segment operating earnings for the fourth quarter of 2017decreased$10.8 million compared to the prior quarter.

• Net interest income decreased due to lower yields on interest earning assets and a higher cost of funds. A $1.8 million decrease in accretion on loans acquired in bank mergers contributed to decreased yields on interest earning assets.

• Provision for credit losses decreased as a result of strong credit performance in 2017. Downward loan risk rating migrations in 2017 were below our historical average, and, as a result, reduced our estimated default probabilities.

• Non-interest income was relatively flat with lower capital markets and international banking fees (mainly swap fees) and a decrease in earnings from investments in Small Business Investment Companies ("SBICs") offset by increases in treasury management and card fees (prepaid and credit cards).

• Non-interest expense increased by $5.3 million compared to the prior quarter. Approximately $2.6 million of these expenses are not expected to repeat in the first quarter of 2018.

• Occupancy and equipment expense increased due to higher building expenses and depreciation related to an investment in infrastructure. Prior quarter expense was positively impacted by a favorable $500 thousand increase in subtenant rent.

4

• Computer services and telecommunication expense increased due to investments in new technology. Approximately $500 thousand of this expense during the quarter in not expected to repeat next quarter.

• Professional and legal expense increased due to greater risk management consulting expense. Approximately $400 thousand of this expense during the quarter in not expected to repeat next quarter.

• Other operating expenses increased due to higher travel, postage, and operating losses. Prior quarter expenses were positively impacted by lower advertising and audit expenses of about $800 thousand in the aggregate.

• Fourth quarter income tax expense includes a $2.1 million increase in state income tax accruals as a result of income allocation to high income tax rate jurisdictions. The prior quarter includes tax benefits of $4.0 million due to the impact of a State of Illinois income tax rate increase and a reduction in compensation related tax accruals.

Banking Segment operating earnings for the year ended December 31, 2017increased$34.1 million compared to the prior year and were positively impacted by strong loan growth, improvements in nearly all key fee initiatives, as well as our merger with American Chartered completed in the third quarter of 2016.

Leasing Segment operating earnings for the fourth quarter of 2017decreased$1.6 million compared to the prior quarter.

• Provision for credit losses increased due to greater loan charge-offs.

• Non-interest expense increased due to higher commission and bonus expense.

• Total assets increased due to growth in loans and lease investments.

Leasing Segment operating earnings for the year ended December 31, 2017 were about the same as the prior year. The increase in lease financing revenue was mostly offset by an increase in provision for credit losses as well as salaries and benefits expense.

• Lease financing revenue increased as a result of higher rental income due to increased operating leases, fees from the sale of third-party equipment maintenance contracts driven by contract renewals, consulting revenue, and promotional income.

• Provision for credit losses was higher due to increased loan charge-offs.

• Non-interest expense increased due to higher salaries and employee benefits expense (increased salaries related to the investment in sales and other revenue generating staff and increased commissions due to higher lease financing revenues) and an increase in other operating expenses.

Mortgage Banking Segment

In December 2017, we closed on an agreement with Champaign, Illinois-based Busey Bank ("Busey") to transfer approximately 165 residential mortgage team members from Busey to our company for approximately $3.6 million. This acquisition adds direct origination capabilities as well as 14 retail mortgage locations across Kansas, Missouri, Nebraska, Iowa and Colorado. The added retail and consumer direct staff supports our strategy to grow those channels and increase our purchase share of originations. Non-interest expenses include approximately $850 thousand during the fourth quarter of 2017 as a result of this acquisition, and additional revenue was negligible as the pipeline was being established.

Mortgage Banking Segment operating earnings for the fourth quarter of 2017decreased$3.0 million compared to the prior quarter.

• Net interest income decreased due to lower average balances and yields on loans held for sale.

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

• Mortgage servicing fees declined due to an increase in amortization and prepayments of mortgage servicing rights and a loss on fair value changes of mortgage servicing rights net of the related economic hedge activity. Nearly $800 thousand of this loss was due to an increase in delinquencies in the fourth quarter of 2017 resulting in higher anticipated collection costs and lower mortgage servicing rights asset value.

• Salaries and employee benefits expense decreased due to lower commissions (lower origination volume and commission rates) partly offset by higher salaries as a result of the increase in staff from the Busey staff transfer.

Mortgage Banking Segment operating earnings for the year ended December 31, 2017decreased$13.4 million compared to the prior 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 and lower gain on sale margin.

• Mortgage servicing revenue decreased as mortgage servicing revenue for the year ended December 31, 2016 was positively impacted by fair value changes of mortgage servicing rights net of the related economic hedge activity of $14.7 million.

• Non-interest expense decreased due to lower salaries and employee benefits expense as a result of lower commission and overtime expenses attributable to a decrease in origination volume, lower bonus expense, and a decline in the number of employees (excluding the staff transferred from Busey).

You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date made. These statements may relate to our future financial performance, strategic plans or objectives, revenues or earnings projections, or other financial items. By their nature, these statements are subject to numerous uncertainties that could cause actual results to differ materially from those anticipated in the statements.

Important factors that could cause actual results to differ materially from the results anticipated or projected include, but are not limited to, the following: (1) the possibility that the actual reduction in our effective tax rate expected to result from Tax Cut and Jobs Act of 2017 might be different from the estimated reduction set forth in this document; (2) the risk that funds obtained from capital raising activities will not be utilized efficiently or effectively; (3) expected revenues, cost savings, synergies, and other benefits from our merger and acquisition activities (including our merger with American Chartered Bancorp, Inc. in 2016) might not be realized within the expected time frames or at all and costs or difficulties relating to integration matters, including but not limited to customer and employee retention, might be greater than expected; (4) the credit risks of lending activities, including changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for loan and lease losses, which could necessitate additional provisions for loan losses, resulting both from originated loans and loans acquired from other financial institutions; (5) the quality and composition of our securities portfolio; (6) competitive pressures among depository institutions; (7) interest rate movements and their impact on customer behavior, net interest margin and the value of our mortgage servicing rights; (8) the possibility that our mortgage banking business may experience increased volatility in its revenues and earnings and the possibility that the profitability of our mortgage banking business could be significantly reduced if we are unable to originate and sell mortgage loans at profitable margins or if changes in interest rates negatively impact the value of our mortgage servicing rights; (9) the impact of repricing and competitors’ pricing initiatives on loan and deposit products; (10) fluctuations in real estate values; (11) results of examinations of us and our bank subsidiary by regulatory authorities and the possibility that any such regulatory authority may, among other things, limit our business activities, require us to change our business mix, increase our allowance for loan and lease losses, write-down asset values or increase our capital levels, or affect our ability to borrow funds or maintain or increase deposits, which could adversely affect our liquidity and earnings; (12) our ability to adapt successfully to technological changes to meet customers’ needs and developments in the market place; (13) the possibility that security measures implemented might not be sufficient to mitigate the risk of a cyber attack or cyber theft, and that such security measures might not protect against systems failures or interruptions; (14) our ability to realize the residual values of our direct finance, leveraged and operating leases; (15) our ability to access cost-effective funding; (16) changes in financial markets; (17) changes in economic conditions in general and in the Chicago metropolitan area in particular; (18) the costs, effects and outcomes of litigation; (19) new legislation or regulatory changes, including but not limited to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”) and regulations adopted thereunder, changes in capital requirements pursuant to the Dodd-Frank Act, changes in the interpretation and/or application of laws and regulations by regulatory authorities, other governmental initiatives affecting the financial services industry and changes in federal and/or state tax laws, including but not limited to the Tax Cut and Jobs Act of 2017, or interpretations thereof by taxing authorities; (20) changes in accounting principles, policies or guidelines; (21) our future acquisitions of other depository institutions or lines of business; and (22) future goodwill impairment due to changes in our business, changes in market conditions, or other factors.

⁽²⁾  Resides in salaries and employee benefits expense on the consolidated statements of operations.

⁽³⁾  Resides in net loss (gain) recognized on other real estate owned and other expense on the consolidated statements of operations.

⁽⁴⁾  Adjustment adds one extra day of salary expense to the second quarter of 2017 and two days to the first quarter of 2017 for comparability purposes. No adjustments made to full year.

The increase in run-rate of non-interest expense was $3.6 million in the fourth quarter of 2017 compared to the prior quarter. Non-interest expenses increased by approximately $850 thousand during the fourth quarter of 2017 as a result of the staff transferred from Busey in December 2017. This $850 thousand represents less than a full month of expense (a full quarter of expense would have been approximately $3.6 million, excluding commissions).

⁽¹⁾  Includes tax benefits on the vesting of restricted shares, exercise of options and other compensation as well as the $2.1 million increase in state income tax accruals as a result of income allocation to high income tax rate jurisdictions for the fourth quarter of 2017.

⁽²⁾  Includes tax benefit due to the impact of the Illinois state income tax rate increase (effective July 1, 2017) on our deferred tax assets and the impact of the Federal income tax rate decrease due to the Tax Cuts and Jobs Act of 2017 (enacted on December 22, 2017) on our net deferred tax liabilities.

⁽³⁾  Includes reversals of a tax liability no longer needed specifically related to two entities we acquired and certain non-deductible merger related items.

We estimate that our effective tax rate in 2018 will be reduced by approximately 10%, due to the TCJ Act, to 24%.

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 merger loans, efficiency ratio, and the ratio of annualized net non-interest expense to average assets with net gains on investment securities, net 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, restructuring severance charges, one-time bonuses, 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 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, restructuring severance charges, one-time bonuses, 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.

4 Full Year Highlights and Impact of 2017 Tax Cuts and Jobs Act

Full Year Highlights 5 See notes starting on page 38. Comparison to 2016 • Operating earnings1 increased $20.6mn, or 10.8%, to $211.1mn. • Diluted operating earnings per common share were $2.39 compared to $2.34 in the prior year (+2.1%). • Loans, excluding purchased credit-impaired loans, increased $1.2bn (+9.8%). Growth was driven by increases in commercial, commercial real estate, and residential real estate loans. • Average yield on loans, excluding accretion on loans acquired in bank mergers, was 4.09%, 20 basis points higher than in the prior year. This increase was driven by several Federal Reserve interest rate increases during 2016 and 2017. • Low-cost deposits increased $416.9mn (+3.4%) to $12.5bn. Growth was driven by a $411.8mn increase in money market, NOW, and interest bearing deposits. • Average cost of total deposits increased 8 basis points to 0.28%. • Credit metrics remained excellent. • Allowance for loan and lease losses to total loans increased 4 basis points to 1.13%. • Net interest margin on a fully tax equivalent basis, excluding accretion on loans acquired in bank mergers, increased three basis points to 3.52%. • Average cost of funds increased 16 basis points to 0.43%. Operating Earnings Loans Deposits Credit Net Interest Margin

2017 Tax Cuts and Jobs Act Impact 6 • Revaluation of net deferred tax liability resulted in one-time tax benefit of $104.2mn and increased regulatory capital ratios 40 to 50 basis points. • Estimated 10% reduction in Company’s effective tax rate to approximately 24% beginning in 2018. • Utilized the benefits of tax reform legislation to reinvest in our communities and employees. • Raised minimum wage to $15 per hour. • Awarded one-time bonuses to eligible employees earning less than $100,000 at an aggregate cost of about $2.7mn. • Contributed $7.5mn to MB Financial Charitable Foundation, which supports nonprofit organizations serving low- and moderate-income communities and households within our service areas. Priority giving areas include affordable housing, community service, economic development, and education. Leasing Segment Impact • Immediate expensing for tax purposes of equipment provides significant acceleration of tax deductions as assets placed in service will be fully deductible. • New limitations on the deductibility of interest expense may increase the appetite for leasing. Mortgage Banking Segment and Other Impacts • Perhaps negligible impact on residential mortgage origination demand due to reduced value of interest deduction. However, jumbo loans represent a small portion of our origination volume. • FDIC premium deductibility phased out, but deductible portion remains at approximately 75%. • NIM on a tax equivalent basis is estimated to decrease by 6 basis points beginning in 2018 due the reduced tax benefit of certain tax-exempt loans and investments.

30 Non-GAAP Disclosure Reconciliations and Footnotes

Non-GAAP Disclosure Reconciliations 31 This presentation 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 margin on a fully tax equivalent basis excluding acquisition accounting discount accretion on bank merger loans, and the ratio of net non-interest expense to average assets with net gains and losses on investment securities, net gains and losses on disposal of other assets, recovery of low income housing investment, and increase in market value of assets held in trust for deferred compensation excluded from the non-interest income components of these ratios, prepayment fees on interest bearing liabilities, and branch exit and facilities impairment charges, merger related and repositioning expenses, restructuring severance charges, one-time bonuses, 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 this ratio, with tax equivalent adjustment for tax-exempt interest income and increase in cash surrender value of life insurance, as applicable; ratios of tangible common equity to tangible assets; operating return on average assets, and 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.

Non-GAAP Disclosure Reconciliations – continued 32 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.

Going forward we then continue to provide an allowance for acquired loans as appropriate. 10) In 2018 the Company expects the tax-equivalent net interest margin will be reduced by about 6 basis points (using 4Q17 balances to estimate), due to calculating tax-equivalent yields on tax-exempt municipal securities and loans at a reduced federal tax rate of 21% as compared to 35% previously. The contractual interest income on these investments, however, will not be impacted by the change in tax rate. 11) Net interest income sensitivity to interest rate changes reflects changes in the composition of interest earning assets and interest bearing liabilities, related interest rates, repricing frequencies, and the fixed or variable characteristics of the interest earning assets and interest bearing liabilities. The changes in net interest income incorporate the impact of loan floors as well as shifts from low-cost deposits to higher cost certificates of deposit in a rising rate environment. The assumptions used in our interest rate sensitivity simulation are inherently uncertain. Amount shown is pre-tax impact and percent change. 12) Excludes purchased credit-impaired loans. 13) The portion of commercial real estate loans that are owner-occupied was approximately 30% ($1.3bn) at 12/31/2017.
