UNAUDITED PRO FORMA COMBINED CONDENSED CONSOLIDATED FINANCIAL INFORMATION

The following is the unaudited pro forma combined condensed consolidated financial information for Byline Bancorp, Inc. (“Byline”) and First Evanston Bancorp, Inc. (“First Evanston”), giving effect to the merger of First Evanston with and into Byline.  The unaudited pro forma combined condensed consolidated statement of financial condition as of March 31, 2018 gives effect to the merger as if it occurred on that date.  The unaudited pro forma combined condensed consolidated statements of operations for the three months ended March 31, 2018 and the year ended December 31, 2017 give effect to the merger as if it occurred on January 1, 2017.  The actual completion date of the merger was May 31, 2018.

The unaudited pro forma combined condensed consolidated financial statements have been prepared using the acquisition method of accounting for business combinations under accounting principles generally accepted in the United States of America (“GAAP”). Byline is the acquirer for accounting purposes. Certain immaterial reclassifications have been made to the historical financial statements of First Evanston to conform to the presentation in Byline’s financial statements.

As of May 31, 2018, the per share cash consideration was based on $27.0 million divided by the number of outstanding shares of First Evanston common stock as of that date, which equaled $16.136 per outstanding share. Based on the closing price of per share of Byline’s common stock of $21.62 on May 31, 2018, as reported by the New York Stock Exchange, and 6,682,850 shares of Byline common stock issued with respect to the outstanding shares of First Evanston common stock, the stock consideration was valued at $144.5 million. Options to acquire 144,090 shares of First Evanston common stock that were outstanding at the time of the merger were converted into options to acquire 680,787 shares of Byline common stock, resulting in a consideration value of $7.6 million. The value of the total merger consideration at closing was $179.1 million.

The unaudited pro forma combined condensed consolidated financial information is presented for illustrative purposes only and does not indicate the financial results or financial condition of the combined company had the companies actually been combined at the dates indicated. The selected unaudited pro forma condensed combined financial information also does not consider any integration expenses, expense efficiencies or other potential effects of the merger. In addition, as explained in more detail in the accompanying notes to the unaudited pro forma combined condensed consolidated financial information, the allocation of the pro forma purchase price is subject to adjustment and may vary significantly from the actual purchase price allocation that will be recorded upon completion of the merger.

Notes to Unaudited Pro Forma Combined Condensed Consolidated Financial Information

(Table dollars in thousands, except share and per share data)

Note 1—Basis of Presentation

The unaudited pro forma combined condensed consolidated financial information has been prepared under the acquisition method of accounting for business combinations.  The unaudited pro forma combined condensed consolidated statements of operations for the year ended December 31, 2017 and three months ended March 31, 2018, are presented as if the acquisition occurred on January 1, 2017.  The unaudited pro forma combined condensed consolidated balance sheet as of March 31, 2018 is presented as if the acquisition occurred as of that date.  This pro forma information does not attempt to predict or suggest future results. It also does not necessarily reflect what the historical results of the combined company Byline and First Evanston would have been had Byline and First Evanston been combined during the periods presented.  The pro forma adjustments are preliminary, based on estimates, and are subject to change as more information becomes available and after final analyses of the fair values of both tangible and intangible assets acquired and liabilities assumed are completed. Accordingly, the final fair value adjustments may be materially different from those presented in this document.

Certain historical data of First Evanston has been reclassified on a pro forma basis to conform with Byline’s classifications.

Note 2—Purchase Price

At the effective time of the Mergers (the “Effective Time”), each share of First Evanston’s common stock (the “First Evanston common stock”) was converted into the right to receive: (1) 3.994 shares of Byline’s common stock, and (2) an amount in cash equal to $27.0 million divided by the number of outstanding shares of First Evanston common stock as of the closing date, with cash paid in lieu of any fractional shares. Options to acquire 144,090 shares of First Evanston common stock that were outstanding at the Effective Time were converted into options to acquire 680,787 shares of Byline common stock, resulting in consideration value of $7.6 million. The per share cash consideration was based on $27.0 million divided by the outstanding shares of First Evanston common stock, or $16.136 per outstanding share. Based on the closing price per share of Byline’s common stock of $21.62 on May 31, 2018, as reported by the New York Stock Exchange, and 6,682,850 shares of Byline common stock issued with respect to the outstanding shares of First Evanston common stock, the stock consideration was valued at $144.5 million. The value of the total merger consideration at closing was $179.1 million.

Note 3—Allocation of Purchase Price of First Evanston

Under the acquisition method of accounting, First Evanston’s assets and liabilities, including identifiable intangible assets, are required to be adjusted to their estimated fair values. The excess of the purchase price over the fair value of the net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments of assets and liabilities included in the unaudited pro forma combined condensed consolidated financial information are based upon available information, and certain assumptions considered reasonable. Fair values are estimated and subject to refinement as additional information becomes available.

E. Estimate of goodwill that would be recognized as part of the transaction if the merger occurred on March 31, 2018.  See the allocation of purchase price for calculation.

F. Estimate of core deposit and customer relationship intangible assets that will be recognized as part of the acquisition accounting.  The core deposit intangible is amortized on an accelerated basis over approximately nine years, while the customer relationship intangible is amortized over 12 years.

G. Net deferred tax asset adjustment related to the acquisition accounting adjustments for loans, the allowance for loan and lease losses, core deposit intangible, customer relationship intangible, premises, furniture, and equipment, time deposits, and junior subordinated debentures issued to capital trust using a tax rate of 27.85%.

H. Fair value adjustment on time deposits. The acquisition accounting adjustment is amortized on an effective yield method over the remaining life of the time deposits acquired.

I. Fair value adjustment on junior subordinated debentures. The acquisition accounting adjustment is amortized on a straight line basis over the remaining life of the junior subordinated debentures acquired.

J. Represents an accrual for estimated transaction costs, net of income tax benefit using a tax rate of 28.51%:

(dollars in thousands)
Change in control payment and share-based award accelerated vesting	$	8,657
Professional fees		2,113	(1)
Pre-tax merger costs		10,770
Income tax benefit		(2,896	)
Total merger costs, net of tax	$	7,874

(1)A portion of this amount is not tax deductible

K. Elimination of First Evanston’s shareholders’ equity, and the issuance of Byline’s shares in the merger. First Evanston’s shareholders were entitled to receive 3.994 shares of Byline’s common stock for each share of First Evanston common stock held by them. The fair value of Byline common stock was based on Byline’s closing price as of May 31, 2018 of $21.62 per share.  Also includes a decrease in retained earnings for estimated transaction costs of $7,874, net of tax.

1. Adjustments to interest and fees on loans and leases reflect the change in loan and lease interest income due to estimated discount accretion associated with fair value adjustments of $28.0 million to acquired loans, assuming the loans had been acquired as of January 1, 2017. The discount accretion was calculated on the effective yield method over the estimated life of the acquired loan portfolio of approximately five years.

2. Adjustments to interest on securities reflect the change in securities income due to estimated discount accretion associated with fair value adjustments of $1.9 million to acquired securities, assuming the securities had been acquired as of January 1, 2017. The discount accretion was calculated on the effective yield method over the estimated lives of the acquired securities of five years.

3. Adjustments to interest on deposits reflect the change in deposit interest expense due to estimated premium amortization associated with fair value adjustments of $712,000 to acquired time deposits, assuming the time deposits had been acquired as of January 1, 2017. The premium amortization was calculated on the effective yield method over the weighted average estimated lives of the acquired time deposits of approximately one year.

(Table dollars in thousands, except share and per share data)

4. Adjustments to interest on borrowings reflect the change in interest expense due to estimated discount accretion associated with the fair value adjustments to assumed junior subordinated debentures issued to capital trust. Adjustments reflect the change in interest expense that would have resulted had the borrowings been acquired as of January 1, 2017. The discount accretion of the fair value adjustment associated with the junior subordinated debenture issued to capital trust of $1.5 million was calculated on the effective yield method over the estimated life of the acquired borrowings of approximately 17 years.

5. Adjustments reflect the reversal of other operating expense related to the acquisition, which are nonrecurring, and will not have a continuing impact on the results of operations.

6. Adjustments to occupancy and equipment expense reflect the premium amortization resulting from a fair value adjustment of acquired buildings of $3.0 million. The amortization of the discount is calculated based on a straight line basis over useful lives ranging from 18 to 33 years.

7. Adjustments are to exclude transaction costs (e.g., advisory and legal) directly related to the acquisition of First Evanston, which are nonrecurring and will not have a continuing impact on the results of operations.

8. Adjustments to other intangible assets amortization expense reflect the change in other expense that would have resulted from the amortization of the core deposit intangible of $19.1 million and customer relationship intangible of $3.2 million had the acquisition occurred as of January 1, 2017. The amortization of the core deposit intangible was calculated on an accelerated basis over an estimated life of approximately nine years and the amortization of the customer relationship intangible was calculated on a straight line basis over an estimated life of 12 years.

9. Adjustments to provision for income taxes reflect recognition of tax expense associated with the adjusted net income before taxes assuming an effective tax rate of 27.85% in 2018 and 40.63% in 2017.

10. Common stock and stock options assumed to be issued by Byline in the merger.
