	FOR IMMEDIATE RELEASE

FIRST MIDWEST BANCORP, INC. ANNOUNCES

RECORD NET INCOME FOR THE THIRD QUARTER OF 2019

CHICAGO, IL, October 22, 2019 – First Midwest Bancorp, Inc. (the "Company" or "First Midwest"), the holding company of First Midwest Bank (the "Bank"), today reported results of operations and financial condition for the third quarter of 2019. Net income for the third quarter of 2019 was $54.5 million, or $0.49 per share, compared to $47.0 million, or $0.43 per share, for the second quarter of 2019, and $53.4 million, or $0.52 per share, for the third quarter of 2018.

Reported results for all periods were impacted by acquisition and integration related expenses and implementation costs related to the Company's Delivering Excellence initiative⁽¹⁾ ("Delivering Excellence"). In addition, the third quarter of 2018 was impacted by the revaluation of deferred tax assets. For additional detail on these adjustments, see the "Non-GAAP Financial Information" section presented later in this release.

Earnings per share ("EPS"), adjusted⁽²⁾ was $0.52 for the third quarter of 2019, compared to $0.50 for the second quarter of 2019 and $0.46 for the third quarter of 2018.

First and foremost, we remain focused on our clients as we work to deliver a superior experience through continued investment in colleagues, systems and efficiency. Second, we continue to expand and diversify our business as evidenced by our pending acquisition of Park Bank, which will see us grow in the Milwaukee and Southeast Wisconsin marketplace. Combined with a strong balance sheet, these efforts position us well as we strive to provide our shareholders with superior, long-term returns."

⁽¹⁾ Interest income and yields on tax-exempt securities and loans are presented on a tax-equivalent basis, assuming a federal income tax rate of 21%. The corresponding income tax impact related to tax-exempt items is recorded in income tax expense. These adjustments have no impact on net income. See the "Non-GAAP Financial Information" section presented later in this release for a discussion of this non-GAAP financial measure.

Net interest income for the third quarter of 2019 was consistent with the second quarter of 2019 and up 14.2% compared to the third quarter of 2018. Compared to both prior periods, the impact of the acquisition of interest-earning assets from the Bridgeview Bancorp, Inc. ("Bridgeview") transaction that closed in the middle of the second quarter of 2019, security purchases, and loan growth was partially offset by higher cost of funds. In addition, net interest income for the third quarter of 2019 benefited from an increase in the number of days in the quarter compared to the second quarter of 2019, partially offset by lower acquired loan accretion. Compared to the third quarter of 2018, the rise in net interest income was also impacted by the acquisition of interest-earning assets from the Northern States Financial Corporation ("Northern States") transaction in the fourth quarter of 2018 and higher acquired loan accretion.

Acquired loan accretion contributed $9.2 million, $10.3 million, and $4.6 million to net interest income for the third quarter of 2019, the second quarter of 2019, and the third quarter of 2018, respectively.

Tax-equivalent net interest margin for the current quarter was 3.82%, decreasing 24 basis points from the second quarter of 2019 and 10 basis points from the third quarter of 2018. Excluding the impact of acquired loan accretion, tax-equivalent net interest margin was 3.59%, down 19 basis points from the second quarter of 2019 and 20 basis point from the third quarter of 2018. Tax-equivalent net interest margin, adjusted reflects the impact of lower market rates on loan yields compared to the second quarter of 2019, and compression related to the mix of interest-earning assets acquired in the Bridgeview transaction compared to the third quarter of 2018. In addition, the decrease compared to both prior periods was impacted by actions taken to reduce rate sensitivity and higher cost of funds.

For the third quarter of 2019, total average interest-earning assets rose by $848.9 million and $2.3 billion from the second quarter of 2019 and third quarter of 2018, respectively. The increase compared to both prior periods resulted primarily from the Bridgeview transaction in the second quarter of 2019, security purchases, and loan growth. In addition, the rise in average interest-earning assets compared to the third quarter of 2018 was impacted by the Northern States transaction.

Total average funding sources for the third quarter of 2019 increased by $869.0 million and $2.3 billion from the second quarter of 2019 and third quarter of 2018, respectively. The increase compared to both prior periods resulted primarily from the Bridgeview transaction in the second quarter of 2019, organic growth, and FHLB advances. In addition, the rise in average funding sources compared to the third quarter of 2018 was impacted by the Northern States transaction.

Total noninterest income	$	42,951	$	38,526	$	35,666	11.5		20.4

Total noninterest income of $43.0 million was up 11.5% and 20.4% from the second quarter of 2019 and third quarter of 2018, respectively. The increase in service charges on deposit accounts and net card-based fees compared to both prior periods was due to services provided to customers acquired in the Bridgeview transaction, as well as seasonally higher volumes compared to the second quarter of 2019 and services provided to customers acquired in the Northern States transaction compared to the third quarter of 2018. Compared to the third quarter of 2018, growth in wealth management fees was driven primarily by customers acquired in the Northern Oak Wealth Management, Inc. ("Northern Oak") transaction completed during the first quarter of 2019.

Capital market products income increased in the third quarter of 2019 as a result of higher sales to corporate clients due to lower long-term rates.

Mortgage banking income for the third quarter of 2019 resulted from sales of $141.0 million of 1-4 family mortgage loans in the secondary market, compared to $93.5 million in the second quarter of 2019 and $61.3 million in the third quarter of 2018. Mortgage banking income is also impacted by changes in the fair value of mortgage servicing rights, which fluctuate from quarter to quarter.

Other income was elevated compared to the third quarter of 2018 due primarily to benefit settlements on bank-owned life insurance and higher fair value adjustments on equity securities.

⁽¹⁾ See the "Non-GAAP Financial Information" section presented later in this release for a discussion of this non-GAAP financial measure.

Total noninterest expense decreased 5.0% from the second quarter of 2019 and increased 12.4% from the third quarter of 2018. Noninterest expense for all periods presented was impacted by acquisition and integration related expenses and costs related to implementation of the Delivering Excellence initiative. Excluding these items, noninterest expense for the third quarter of 2019 was $104.8 million, consistent with the second quarter of 2019 and up 11.2% from the third quarter of 2018.

Operating costs associated with the Bridgeview transaction completed during the middle of the second quarter of 2019 contributed to noninterest expense for the third quarter of 2019. In addition, operating costs associated with the Northern Oak and Northern States transactions contributed to the increase in noninterest expense compared to the third quarter of 2018. These costs primarily occurred in salaries and employee benefits, net occupancy and equipment expense, professional services, and other expenses.

Compared to both prior periods, the increase in salaries and employee benefits was also impacted by higher commissions resulting from sales of 1-4 family mortgage loans in the secondary market. In addition, salaries and employee benefits compared to the third quarter of 2018 rose due to merit increases. The decrease in professional services compared to the second quarter of 2019 was driven primarily by the timing of certain other professional fees and the increase compared to the third quarter of 2018 resulted from organizational growth. Advertising and promotions expense decreased compared to both prior periods due to the timing of certain costs related to marketing campaigns, as well as a contribution to the First Midwest Charitable Foundation in the third quarter of 2018. Net OREO expense for the third quarter of 2018 was impacted by higher levels of gains on sales of properties. The decrease in other expenses compared to the second quarter of 2019 was driven primarily by lower property valuation adjustments and a reduction in Federal Deposit Insurance Corporation premiums due to small bank assessment credits received.

Acquisition and integration related expenses for the third quarter of 2019 resulted primarily from the acquisition of Bridgeview and the pending acquisition of Park Bank. For the second quarter of 2019, acquisition and integration related expenses resulted primarily from the acquisition of Bridgeview.

Delivering Excellence implementation costs for all periods presented resulted from certain actions initiated by the Company in connection with its Delivering Excellence initiative and include property valuation adjustments on locations identified for closure, employee severance, and general restructuring and advisory services.

Total loans of $12.8 billion increased 8.0%, annualized from June 30, 2019 and by 15.6% from September 30, 2018. Excluding loans acquired in the Bridgeview and Northern States transactions as of September 30, 2019, total loans grew by 7.8% from September 30, 2018. In addition, total corporate loans compared to both prior periods benefited from growth in commercial and industrial loans, primarily within our sector-based lending and middle market business units, and multifamily loans. Strong production within commercial real estate loans was offset by the impact of the decision of certain customers to opportunistically sell their commercial business or investment real estate properties, as well as refinancing with non-bank lenders and real estate investors.

Growth in consumer loans compared to both prior periods resulted primarily from purchases of 1-4 family mortgages and organic growth.

⁽¹⁾ Purchased credit impaired loans with an accretable yield are considered current and are not included in past due loan totals.

⁽²⁾ Foreclosed assets consists of OREO and other foreclosed assets acquired in partial or total satisfaction of defaulted loans. Other foreclosed assets are included in other assets in the Consolidated Statements of Financial Condition.

⁽³⁾ This ratio includes acquired loans that are recorded at fair value through an acquisition adjustment, which incorporates credit risk as of the acquisition date with no allowance for credit losses being established at that time. As the acquisition adjustment is accreted into income over future periods, an allowance for credit losses on acquired loans is established as necessary to reflect credit deterioration.

Total non-performing assets represented 0.85% of total loans and foreclosed assets at September 30, 2019 compared to 0.77% and 0.74% at June 30, 2019 and September 30, 2018, respectively, reflective of normal fluctuations that occur on a quarterly basis. The increase in non-accrual loans from June 30, 2019 was driven primarily by the transfer of two corporate loan relationships to non-accrual during the third quarter of 2019, for which the Company has remediation plans in place. In addition, included in foreclosed assets as of September 30, 2019 and June 30, 2019 was $3.9 million and $6.2 million, respectively, of OREO acquired in the Bridgeview transaction.

The allowance for credit losses to total loans was 0.86% at September 30, 2019, compared to 0.85% at June 30, 2019 and 0.91% at September 30, 2018. The decrease compared to September 30, 2018 was driven primarily by loans acquired in the Bridgeview transaction, for which no allowance for credit losses was established at the time of acquisition in accordance with accounting guidance applicable to business combinations.

The increase in total average deposits compared to both prior periods was driven primarily by deposits assumed in the Bridgeview transaction during the middle of the second quarter of 2019 and organic growth. In addition, growth in total average deposits was impacted by the normal seasonal increase in municipal deposits compared to the second quarter of 2019 and deposits assumed in the Northern States transaction, as well as various time deposit marketing initiatives compared to the third quarter of 2018.

CAPITAL MANAGEMENT

Capital Ratios

	As of
	September 30, 2019		June 30, 2019		December 31, 2018		September 30, 2018
Company regulatory capital ratios:
Total capital to risk-weighted assets	12.62	%	12.57	%	12.62	%	12.32	%
Tier 1 capital to risk-weighted assets	10.18	%	10.11	%	10.20	%	10.34	%
Common equity Tier 1 ("CET1") to risk-weighted assets	10.18	%	10.11	%	10.20	%	9.93	%
Tier 1 capital to average assets	8.67	%	8.96	%	8.90	%	9.10	%
Company tangible common equity ratios(1)(2):
Tangible common equity to tangible assets	8.54	%	8.57	%	8.59	%	8.21	%
Tangible common equity, excluding accumulated other comprehensive   income ("AOCI"), to tangible assets	8.50	%	8.59	%	8.95	%	8.74	%
Tangible common equity to risk-weighted assets	10.24	%	10.11	%	9.81	%	9.33	%

⁽¹⁾ These ratios are not subject to formal Federal Reserve regulatory guidance.

⁽²⁾ Tangible common equity ("TCE") represents common stockholders' equity less goodwill and identifiable intangible assets. For details of the calculation of these ratios, see the sections titled, "Non-GAAP Financial Information" and "Non-GAAP Reconciliations" presented later in this release.

Capital ratios were consistent compared to December 31, 2018 as strong earnings and deferred gains recognized due to the adoption of lease accounting guidance at the beginning of 2019 were offset by the Bridgeview and Northern Oak acquisitions, the impact of loan growth and securities purchases on risk-weighted assets, and stock repurchases. In addition, capital ratios compared to September 30, 2018 were impacted by the phase-out of Tier 1 treatment of the Company's trust-preferred securities and the Northern States transaction in the fourth quarter of 2018.

During the first quarter of 2019, the Company announced a new stock repurchase program that authorizes the Company to repurchase up to $180 million of its common stock. Stock repurchases under this program may be made from time to time on the open market or in privately negotiated transactions, at the discretion of the Company. The Company repurchased approximately 645,000 shares of its common stock at a total cost of $12.7 million during the third quarter of 2019. As of September 30, 2019, the Company had remaining authorization to purchase $146.1 million of its common stock.

The Board of Directors approved a quarterly cash dividend of $0.14 per common share during the third quarter of 2019, which follows an increase of 17% from the first quarter of 2019 and is a 27% increase from the third quarter of 2018. This dividend represents the 147^th consecutive cash dividend paid by the Company since its inception in 1983.

Forward-Looking Statements

This press release, as well as any oral statements made by or on behalf of First Midwest, may contain certain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. In some cases, forward-looking statements can be identified by the use of words such as "may," "might," "will," "would," "should," "could," "expect," "plan," "intend," "anticipate," "believe," "estimate," "outlook," "predict," "project," "probable," "potential," "possible," "target," "continue," "look

forward," or "assume" and words of similar import. Forward-looking statements are not historical facts or guarantees of future performance but instead express only management's beliefs regarding future results or events, many of which, by their nature, are inherently uncertain and outside of management's control. It is possible that actual results and events may differ, possibly materially, from the anticipated results or events indicated in these forward-looking statements. First Midwest cautions you not to place undue reliance on these statements. Forward-looking statements speak only as of the date made, and First Midwest undertakes no obligation to update any forward-looking statements.

Forward-looking statements may be deemed to include, among other things, statements relating to First Midwest's future financial performance, including the related outlook for 2019, the performance of First Midwest's loan or securities portfolio, the expected amount of future credit reserves or charge-offs, corporate strategies or objectives, including the impact of certain actions and initiatives, First Midwest's Delivering Excellence initiative, including costs and benefits associated therewith and the timing thereof, anticipated trends in First Midwest's business, regulatory developments, the impact of federal income tax reform legislation, acquisition transactions, including First Midwest's proposed acquisition of Bankmanagers, estimated synergies, cost savings and financial benefits of announced and completed transactions, and growth strategies, including possible future acquisitions. These statements are subject to certain risks, uncertainties and assumptions, including those discussed under the sections entitled "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations" in First Midwest's Annual Report on Form 10-K for the year ended December 31, 2018, and in First Midwest's subsequent filings made with the Securities and Exchange Commission ("SEC"). These risks and uncertainties are not exhaustive, and other sections of these reports describe additional factors that could adversely impact First Midwest's business and financial performance.

Non-GAAP Financial Information

The Company's accounting and reporting policies conform to U.S. generally accepted accounting principles ("GAAP") and general practices within the banking industry. As a supplement to GAAP, the Company provides non-GAAP performance results, which the Company believes are useful because they assist investors in assessing the Company's operating performance. These non-GAAP financial measures include EPS, adjusted, the efficiency ratio, return on average assets, adjusted, tax-equivalent net interest income (including its individual components), tax-equivalent net interest margin, tax-equivalent net interest margin, adjusted, noninterest expense, adjusted, effective income tax rate, adjusted, tangible common equity to tangible assets, tangible common equity, excluding AOCI, to tangible assets, tangible common equity to risk-weighted assets, return on average common equity, adjusted, return on average tangible common equity, and return on average tangible common equity, adjusted.

The Company presents EPS, the efficiency ratio, return on average assets, return on average common equity, and return on average tangible common equity, all adjusted for certain significant transactions. These transactions include acquisition and integration related expenses associated with completed and pending acquisitions (all periods), Delivering Excellence implementation costs (all periods), and certain income tax benefits resulting from tax reform (third quarter of 2018). Management believes excluding these transactions from EPS, the efficiency ratio, return on average assets, return on average common equity, and return on average tangible common equity may be useful in assessing the Company's underlying operational performance since these transactions do not pertain to its core business operations and their exclusion may facilitate better comparability between periods. Management believes that excluding acquisition and integration related expenses from these metrics may be useful to the Company, as well as analysts and investors, since these expenses can vary significantly based on the size, type, and structure of each acquisition. Additionally, management believes excluding these transactions from these metrics may enhance comparability for peer comparison purposes.

The Company presents noninterest expense, adjusted, which excludes acquisition and integration related expenses and Delivering Excellence implementation costs. In addition, the Company presents the effective income tax rate, adjusted, which excludes certain income tax benefits aligned with tax reform. Management believes that excluding these items from noninterest expense and the effective income tax rate may be useful in assessing the Company’s underlying operational performance as these items either do not pertain to its core business operations or their exclusion may facilitate better comparability between periods and for peer comparison purposes.

The tax-equivalent adjustment to net interest income and net interest margin recognizes the income tax savings when comparing taxable and tax-exempt assets. Interest income and yields on tax-exempt securities and loans are presented using the current federal income tax rate of 21%. Management believes that it is standard practice in the banking industry to present net interest income and net interest margin on a fully tax-equivalent basis and that it may enhance comparability for peer comparison purposes. In addition, management believes that presenting tax-equivalent net interest margin, adjusted, may enhance comparability for peer comparison purposes and is useful to the Company, as well as analysts and investors, since acquired loan accretion income may fluctuate based on the size of each acquisition, as well as from period to period.

10

In management's view, tangible common equity measures are capital adequacy metrics that may be meaningful to the Company, as well as analysts and investors, in assessing the Company's use of equity and in facilitating comparisons with peers. These non-GAAP measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from stockholders' equity and retain the effect of accumulated other comprehensive loss in stockholders' equity.

Although intended to enhance investors' understanding of the Company's business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. In addition, these non-GAAP financial measures may differ from those used by other financial institutions to assess their business and performance. See the previously provided tables and the following reconciliations in the "Non-GAAP Reconciliations" section for details on the calculation of these measures to the extent presented herein.

Footnotes to Selected Financial Information

⁽¹⁾  See the "Non-GAAP Reconciliations" section for the detailed calculation.

⁽²⁾  Annualized based on the actual number of days for each period presented.

⁽³⁾  Presented on a tax-equivalent basis, assuming the applicable federal income tax rate of 21%.

⁽⁴⁾  Cost of funds expresses total interest expense as a percentage of total average funding sources.

⁽⁵⁾  Foreclosed assets consists of OREO and other foreclosed assets acquired in partial or total satisfaction of defaulted loans. Other foreclosed assets are included in other assets in the Consolidated Statements of Financial Condition.

⁽⁶⁾  This ratio includes acquired loans that are recorded at fair value through an acquisition adjustment, which incorporates credit risk, as of the acquisition date with no allowance for credit losses being established at that time. As the acquisition adjustment is accreted into income over future periods, an allowance for credit losses is established on acquired loans as necessary to reflect credit deterioration.
