These unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (“SEC”). In preparing these financial statements, the Company has evaluated events and transactions subsequent to March 31, 2022 for potential recognition or disclosure. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information in footnote disclosures normally included in financial statements prepared in accordance with GAAP has been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Consolidated Financial Statements for the years ended December 31, 2021, 2020, and 2019.

The Company has one reportable segment. The Company’s chief operating decision maker evaluates the operations of the Company using consolidated information for purposes of allocating resources and assessing performance. Therefore, segments disclosures are not required.

In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 855, “Subsequent Events,” the Company’s management has evaluated subsequent events for potential recognition or disclosure through the date of the issuance of these condensed consolidated financial statements. No subsequent events were identified that would have required a change to the condensed consolidated financial statements or disclosure in the notes to the condensed consolidated financial statements.

Certain prior period amounts have been reclassified to conform to current period presentation. These reclassifications did not result in any changes to previously reported net income or stockholders’ equity.

Note 2—Accounting Pronouncements Recently Adopted or Issued

The following reflect recent accounting pronouncements that have been adopted or are pending adoption by the Company. As the Company qualifies as an emerging growth company and has elected the extended transition period for complying with new or revised accounting pronouncements, it is not subject to new or revised accounting standards applicable to public companies during the extended transition period. The accounting pronouncements pending adoption below reflect effective dates for the Company as an emerging growth company with the extended transition period.

Adopted Accounting Pronouncement

Income Taxes (Topic 740)—On January 1, 2022, the Company adopted ASU No. 2019-12, Simplifying the Accounting for Income Taxes. The ASU simplifies the accounting for income taxes by removing the following: the exception to the incremental approach for intraperiod tax allocation when there is a loss from continuing operations and income or a gain from other items; the exception to the requirement to or not to recognize a deferred tax liability for a foreign entity when it becomes an equity method investment or it becomes a subsidiary, respectively; and the exception to the general methodology for calculating income taxes in an interim period when a year-to-date loss exceeds the anticipated loss for the year. The amendments in the ASU change current authoritative guidance by requiring the recognition of franchise tax that is partially based on income as an income-based tax and account for any incremental amount incurred as a non-income-based tax; requiring an evaluation when a step up in the tax basis of goodwill should be considered part the of business combination; specifying that it is not required to allocate the consolidated amount of current and deferred tax expense to a legal entity that is not subject to tax in its separate financial statements; and requiring that an entity reflect the effect of an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. Adoption of the provisions of ASU No. 2019-12 did not impact our financial result for the three months ended March 31, 2022.

Issued Accounting Pronouncements Pending Adoption

Financial Instruments—Credit Losses (Topic 326)—In June 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2016‑13, Measurement of Credit Losses on Financial Instruments. Current GAAP requires an “incurred loss” methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. The main objective of this ASU is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. The amendments in this ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU require a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The measurement of expected credit losses will be based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Upon adoption, a banking organization must record a one-time adjustment to its credit loss allowances as of the beginning of the fiscal year of adoption equal to the difference, if any, between the amount of credit loss allowances under the prior methodology and the amount required under the new standard. The amendments in this ASU broaden the information that an entity must consider in developing its expected credit loss estimate for assets measured either collectively or individually. The use of forecasted information incorporates more timely information in the estimate of expected credit loss, which will be more useful to users of the financial statements. In February 2022, FASB issued ASU No. 2022-02, Troubled Debt Restructurings (TDRs) and Vintage Disclosures, which eliminates the specific accounting guidance for TDRs and updates the vintage disclosure requirements to require disclosure of current period charge-offs by year of origination. This guidance will be implemented upon adoption. In November 2019, FASB issued ASU No. 2019-10, Effective Dates, which delays the effective date of the ASU for entities not classified as Public Business Entities. The Company will adopt the standard on December 31, 2022. The new guidance may result in an increase in the allowance for loan losses, which will reflect the requirement to include expected losses on purchased credit-impaired loans. The extent of the increase will depend on the composition of the loan portfolio, as well as the economic conditions and forecasts as of the adoption date.

Reference Rate Reform (Topic 848)—In March 2020, FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in the ASU provide optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The amendments in the ASU provide optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The ASU is intended to help stakeholders during the global market-wide reference rate transition period. The amendments in the ASU will be in effect for all entities as of March 12, 2020 through December 31, 2022. Banking regulators have provided guidance which prohibits new financial contracts from referencing LIBOR as the relevant index after December 31, 2021. The guidance goes on to indicate that beginning after June 2023, LIBOR can no longer be used for existing financial contracts. In December 2021, management approved the use of Term Secured Overnight Financing Rate ("SOFR") as an alternative reference rate to LIBOR. Other alternative reference rates may be considered in the future. At March 31, 2022, $1.1 billion of loans, derivatives with a notional amount of $475.8 million, and securities available for sale with a fair value of $58.3 million, include fallback provisions that define the trigger events (an occurrence that precipitates the conversion from LIBOR to a new reference rate), and allow for the selection of a benchmark replacement and a spread adjustment between LIBOR and that benchmark replacement. Junior subordinated debentures carrying value of $37.0 million were also tied to LIBOR.

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. The Company evaluated the securities that had an unrealized loss for other than temporary impairment and determined all declines in value to be temporary. There were 223 securities available-for-sale with unrealized losses at March 31, 2022. There were no securities held-to-maturity with unrealized losses at March 31, 2022. The Company anticipates full recovery of amortized cost with respect to these securities by maturity. The Company does not intend to sell these securities and it is not more likely than not that the Company will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The proceeds from all sales of securities available-for-sale, and the associated gains and losses on sales and calls of securities, for the three months ended March 31, 2022 and 2021 are listed below:

Originated loans and leases represent originations excluding loans initially acquired in a business combination. However, once an acquired non-impaired loan reaches its maturity date, and is re-underwritten and renewed, it is internally classified as an originated loan. Acquired impaired loans are loans acquired from a business combination with evidence of credit quality deterioration and are accounted for under ASC Topic 310-30. Acquired non-impaired loans and leases represent loans and leases acquired from a business combination without more than insignificant evidence of credit quality deterioration and are accounted for under ASC Topic 310-20. Acquired leases and revolving loans having evidence of credit quality deterioration do not qualify to be accounted for as acquired impaired loans and are accounted for under ASC Topic 310-20. The following tables summarize the balances for each respective loan and lease category as of March 31, 2022 and December 31, 2021:

Note 5—Allowance for Loan and Lease Losses and Reserve for Unfunded Commitments

Loans and leases considered for inclusion in the allowance for loan and lease losses include acquired non-impaired loans and leases, those acquired impaired loans with credit deterioration after acquisition, and originated loans and leases. Although all acquired loans and leases are included in the following table, only those with credit deterioration subsequent to acquisition date are included in the allowance for loan and lease losses.

The following tables summarize the balance and activity within the allowance for loan and lease losses, the components of the allowance for loan and lease losses in terms of loans and leases individually and collectively evaluated for impairment, and corresponding loan and lease balances by type for the three months ended March 31, 2022 and 2021 are as follows:

For loans individually evaluated for impairment, the Company decreased the allowance for loan and lease losses for the three months ended March 31, 2022 by $299,000. The Company increased the allowance on loans individually evaluated for impairment by $2.4 million for the three months ended March 31, 2021. For loans collectively evaluated for impairment, the Company increased allowance for loan and lease losses by $4.9 million for the three months ended March 31, 2022, and recaptured $824,000 of the allowance for the three months ended March 31, 2021, respectively.

An allowance for loan and lease loss allocation has not been made for PPP loans as these loans are fully guaranteed by the Small Business Association ("SBA"). On a quarterly basis, the Company assesses the collectability of its government guarantee loan and lease portfolio using historical loss experience in its small business lending unit.

The following tables summarize the recorded investment, unpaid principal balance, and related allowance for loans and leases losses considered impaired as of March 31, 2022 and December 31, 2021, which exclude acquired impaired loans. For purposes of these tables, the unpaid principal balance represents the outstanding contractual balance. Impaired loans include loans that are individually evaluated for impairment as well as troubled debt restructurings for all loan categories. The sum of non-accrual loans and loans past due 90 days still on accrual will differ from the total impaired loan amount.

Note 6—Servicing Assets

Activity for servicing assets and the related changes in fair value for the three months ended March 31, 2022 and 2021 was as follows:

	Three Months Ended <br>March 31,
	2022			2021

Additions, net		1,984			1,603
Changes in fair value		(1,231	)		(1,505	)
Ending balance	$	24,497		$	22,140

Loans serviced for others are not included in the Consolidated Statements of Financial Condition. The unpaid principal balances of these loans serviced for others as of March 31, 2022 and December 31, 2021 were as follows:

		December 31,
		2021
Loan portfolios serviced for:
SBA guaranteed loans	1,514,240	$	1,510,375
A guaranteed loans	190,797		183,026
Total	1,705,037	$	1,693,401

All values are in US Dollars.

Loan servicing revenue totaled $3.4 million and $2.8 million for each of the three months ended March 31, 2022 and 2021, respectively. Loan servicing asset revaluation, which represents the changes in fair value of servicing assets, resulted in a downward valuation adjustment of $1.2 million and $1.5 million for three months ended March 31, 2022 and 2021, respectively.

The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in secondary market premiums and prepayment speed assumptions have the most significant impact on the fair value of servicing rights.

Generally, as interest rates rise on variable rate loans, loan prepayments increase due to an increase in refinance activity, which may result in a decrease in the fair value of servicing assets. Measurement of fair value is limited to the conditions existing and the assumptions used as of a particular point in time, and those assumptions may change over time. Refer to Note 15—Fair Value Measurement for further details.

At March 31, 2022 and December 31, 2021, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process was $3.2 million and $2.5 million, respectively.

There were no internally financed sales of OREO for the three months ended March 31, 2022 or 2021.

Note 8—Leases

The Company enters into leases in the normal course of business primarily for its banking facilities and branches. The Company’s operating leases have varying maturity dates through year end

2042

, some of which include renewal or termination options to extend the lease. In addition, the Company leases or subleases real estate to third parties. The Company includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Company will exercise the option. In addition, the Company has elected to account for any non-lease components in its real estate leases as part of the associated lease component. The Company has also elected not to recognize leases with original lease terms of 12 months or less (short-term leases) on the Company’s Condensed Consolidated Statements of Financial Condition. Leases are classified at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

The following table summarizes the amount and balance sheet line item for our operating lease right-of-use asset and liability as of March 31, 2022:

	Balance Sheet Line Item	March 31, 2022		December 31, 2021
Operating lease right-of-use asset	Accrued interest receivable and other assets	$	11,769	$	11,646
Operating lease liability	Accrued interest payable and other liabilities		15,562		15,629

The Company uses its incremental borrowing rate at lease commencement to calculate the present value of lease payments when the rate implicit in a lease is not known. The Company’s incremental borrowing rate is based on the FHLB regular advance rate, adjusted for the lease term and other factors. At March 31, 2022, the weighted-average discount rate of operating leases was 1.19% and the weighted average remaining life of operating leases was

5.9

years, compared to 0.99% and

6.0

years as of December 31, 2021. The following table presents components of total lease costs included as a component of occupancy expense on the Consolidated Statement of Operations for the following periods:

	Three Months Ended <br>March 31,
	2022			2021
Operating lease cost	$	858		$	865
Short-term lease cost		37			96

The Company’s rental expenses for the three months ended March 31, 2022 and 2021 were $1.4 million. For the three months ended March 31, 2022 and 2021, the Company received $127,000 and $154,000, respectively, in sublease income. The total amount of minimum rentals to be received in the future on these subleases is approximately $1.3 million, and the leases have contractual lives extending through

2026

. In addition to the above required lease payments, the Company has contractual obligations related primarily to information technology contracts and other maintenance contracts.

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

The effective tax rate for the three months ended March 31, 2022 and 2021 was 22.0% and 25.3%, respectively. The decrease in the effective tax rate during the first quarter of 2022 was a result of income tax benefits related to share-based compensation. The Company recorded discrete income tax benefit of $1.1 million and $28,000 related to the exercise of stock options and vesting of restricted shares for the three months ended March 31, 2022 and 2021, respectively.

Net deferred tax assets increased to $67.3 million at March 31, 2022 compared to $50.3 million at December 31, 2021 primarily as a result of unrealized losses on available-for-sale securities.

At March 31, 2022, fixed-rate Federal Home Loan Bank (“FHLB”) advances totaled $80.0 million, with interest rates ranging from 0.00% to 0.66% and maturities ranging from May 2022 to June 2022. Total variable rate advances were $200.0 million at March 31, 2022, with interest rates of 0.44% and 0.49% that may reset daily, and mature in May 2022. Advances from the FHLB are collateralized by residential real estate loans, commercial real estate loans, and securities. The Bank’s maximum borrowing capacity is limited to 35% of total assets. Required investment in FHLB stock is $4.50 for every $100 in advances thereafter.

Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. The Company pledges securities as collateral for the repurchase agreements. Refer to Note 3—Securities for additional discussion.

On October 13, 2016, the Company entered into a $30.0 million revolving credit agreement with a correspondent bank. Through subsequent amendments, the revolving credit agreement was reduced to $15.0 million and the maturity of the credit facility was extended to October 7, 2022. The amended revolving line of credit bears interest at either LIBOR plus 195 basis points or the Prime Rate minus 75 basis points, not to be less than 2.00%, based on the Company’s election, which is required to be communicated at least three business days prior to the commencement of an interest period. If the Company fails to provide timely notification, the interest rate will be Prime Rate minus 75 basis points. At March 31, 2022 and December 31, 2021, the line of credit had no outstanding balance.

The following table presents short-term credit lines available for use as of March 31, 2022 and December 31, 2021:

	March 31,		December 31,

The Company hedges interest rates on borrowed funds using interest rate swaps through which the Company receives variable amounts and pays fixed amounts. Refer to Note 16—Derivative Instruments and Hedging Activities for additional discussion.

Note 13—Subordinated Notes and Junior Subordinated Debentures

In 2020, the Company issued $75.0 million in fixed-to-floating subordinated notes that mature on July 1, 2030. The subordinated notes bear a fixed interest rate of 6.00% until July 1, 2025 and a floating interest rate equal to a benchmark rate, which is expected to be the three-month SOFR, plus 588 basis points thereafter until maturity. The transaction resulted in debt issuance costs of approximately $1.7 million that will be amortized over 10 years.

As of March 31, 2022, the net liability outstanding of the subordinated notes was $73.6 million. The Company may, at its option, redeem the notes, in whole or in part, on a semi-annual basis beginning on July 1, 2025, subject to obtaining the prior approval of the Federal Reserve to the extent such approval is then required. The subordinated notes qualify as Tier 2 capital for regulatory capital purposes.

At March 31, 2022 and December 31, 2021, the Company’s junior subordinated debentures by issuance were as follows:

Name of Trust	Aggregate Principal Amount March 31, 2022			Aggregate<br>Principal Amount<br>December 31, 2021			Stated<br>Maturity	Contractual Rate at March 31, 2022			Interest Rate Spread
Metropolitan Statutory Trust 1	$	35,000		$	35,000		March 17, 2034		3.71	%	Three-month<br>LIBOR + 2.79%
First Evanston Bancorp Trust I		10,000			10,000		March 15, 2035		2.61	%	Three-month<br>LIBOR + 1.78%

debentures bear interest at three-month LIBOR plus 2.79% (3.71% and 3.01% at March 31, 2022 and December 31, 2021, respectively). Interest is paid on a quarterly basis. The Company has the right to redeem the debentures, in whole or in part, on any interest payment date on or after March 2009. Accrued interest payable was $56,000 and $45,000 as of March 31, 2022 and December 31, 2021, respectively.

As part of the First Evanston acquisition, the Company assumed the obligations to First Evanston Bancorp Trust I of $10.0 million in principal amount, which was formed for the issuance of trust preferred securities. Beginning on March 15, 2010, the interest rate reset to the three-month LIBOR plus 1.78% (2.61% and 1.98% at March 31, 2022 and December 31, 2021, respectively), which is in effect until the debentures mature in 2035. Interest is paid on a quarterly basis. The Company has the right to redeem the debentures, in whole or in part, on any interest payment date on or after March 2010. The Company has the option to defer interest payments on the debentures from time to time for a period not to exceed five consecutive years. Accrued interest payable was $12,000 and $9,000 as of March 31, 2022 and December 31, 2021, respectively.

The Trusts are not consolidated with the Company. Accordingly, the Company reports the subordinated debentures held by the Trusts as liabilities. The Company owns all of the common securities of each trust. The junior subordinated debentures qualify, and are treated as, Tier 1 regulatory capital of the Company subject to regulatory limitations. The trust preferred securities issued by each trust rank equally with the common securities in right of payment, except that if an event of default under the indenture governing the notes has occurred and is continuing, the preferred securities will rank senior to the common securities in right of payment.

Note 14—Commitments and Contingent Liabilities

Legal contingencies—In the ordinary course of business, the Company and Bank have various outstanding commitments and contingent liabilities that are not recognized in the accompanying consolidated financial statements. In addition, the Company may be a defendant in certain claims and legal actions arising in the ordinary course of business. In the opinion of management, after consultation with legal counsel, the ultimate disposition of these matters is currently not expected to have a material adverse effect on the Company’s Consolidated Financial Statements.

Operating lease commitments—Refer to Note 8—Leases for discussion of operating lease commitments.

Commitments to extend credit—The Company is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement the Company has in particular classes of financial instruments.

The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and letters of credit is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for funded instruments. The Company does not anticipate any material losses as a result of the commitments and letters of credit.

The following table summarizes the contract or notional amount of outstanding loan and lease commitments at March 31, 2022 and December 31, 2021:

	March 31, 2022						December 31, 2021
	Fixed Rate		Variable Rate		Total		Fixed Rate		Variable Rate		Total
Commitments to extend credit	$	247,494	$	1,666,980	$	1,914,474	$	176,014	$	1,578,405	$	1,754,419
Letters of credit		579		57,745		58,324		599		58,543		59,142
Total	$	248,073	$	1,724,725	$	1,972,798	$	176,613	$	1,636,948	$	1,813,561

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Company upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

28

BYLINE BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

Letters of credit are conditional commitments issued by the Company to guarantee to a third-party the performance of a customer. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 1.25% to 18.00% and maturities up to

2045

. Variable rate loan commitments have interest rates ranging from 1.25% to 15.00% and maturities up to

2048

.

Note 15—Fair Value Measurement

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. In addition, the Company has the ability to obtain fair values for markets that are not accessible.

These types of inputs create the following fair value hierarchy:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the asset or liability. Unobservable inputs are used to measure fair value to the extent that observable inputs are not available. The Company’s own data used to develop unobservable inputs may be adjusted for market considerations when reasonably available.

The categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to assets and liabilities.

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a recurring basis:

Securities available-for-sale—The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as matrix or model pricing.

The Company’s methodology for pricing non-rated bonds focuses on three distinct inputs: equivalent rating, yield and other pricing terms. To determine the rating for a given non-rated municipal bond, the Company references a publicly issued bond by the same issuer if available as well as other additional key metrics to support the credit worthiness. Typically, pricing for these types of bonds would require a higher yield than a similar rated bond from the same issuer. A reduction in price is applied to the rating obtained from the comparable bond, as the Company believes if liquidated, a non-rated bond would be valued less than a similar bond with a verifiable rating. The reduction applied by the Company is one notch lower (i.e. a “AA” rating for a comparable bond would be reduced to “AA-” for the Company’s valuation). In 2022 and 2021, all of the ratings derived by the Company were “BBB” or better with and without comparable bond proxies. The fair value measurement of municipal bonds is sensitive to the rating input, as a higher rating typically results in an increased valuation. The remaining pricing inputs used in the bond valuation are observable. Based on the rating determined, the Company obtains a corresponding current market yield curve available to market participants. Other terms including coupon, maturity date, redemption price, number of coupon payments per year, and accrual method are obtained from the individual bond term sheets.

Equity and other securities—The Company utilizes the same fair value measurement methodology for equity and other securities as detailed in the securities available-sale portfolio above.

Servicing assets—Fair value is based on a loan-by-loan basis taking into consideration the original term to maturity, the current age of the loan and the remaining term to maturity. The valuation methodology utilized for the servicing assets begins with generating estimated future cash flows for each servicing asset, based on their unique characteristics and

29

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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

market-based assumptions for prepayment speeds and costs to service. The present value of the future cash flows are then calculated utilizing market-based discount rate assumptions.

Derivative instruments—Interest rate derivatives are valued by a third party, using models that primarily use market observable inputs, such as yield curves, and are validated by comparison with valuations provided by the respective counterparties. Derivative financial instruments are included in other assets and other liabilities in the Condensed Consolidated Statements of Financial Condition.

The following tables summarize the Company’s financial assets and liabilities that were measured at fair value on a recurring basis at March 31, 2022 and December 31, 2021:

The Company used the following methods and significant assumptions to estimate fair value for certain assets measured and carried at fair value on a non-recurring basis:

Impaired loans (excluding acquired impaired loans)—Impaired loans, other than those existing on the date of a business acquisition, are primarily carried at the fair value of the underlying collateral, less estimated costs to sell, if the loan is collateral dependent. Valuations of impaired loans that are collateral dependent are supported by third party appraisals in accordance with the Bank’s credit policy. Other valuation methods include analysis of discounted cash flows, which measures the present value of expected future cash flows discounted at the loan’s effective interest rate. Impaired loans that are not collateral dependent are not material.

Assets held for sale—Assets held for sale consist of former branch locations and real estate previously purchased for expansion. Assets are considered held for sale when management has approved to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based on the lower of carrying value or its fair value, less estimated costs to sell. The Company records assets held for sale on the Condensed Consolidated Statements of Financial Condition within accrued interest receivable and other assets.

Other real estate owned—Certain assets held within other real estate owned represent real estate or other collateral that has been adjusted to its estimated fair value, less cost to sell, as a result of transferring from the loan portfolio at the time of foreclosure or repossession and based on management’s periodic impairment evaluation. From time to time, non-recurring fair value adjustments to other real estate owned are recorded to reflect partial write-downs based on an observable market price or current appraised value of property.

Adjustments to fair value based on such non-recurring transactions generally result from the application of lower-of-cost-or-market accounting or write-downs of individual assets due to impairment. The following tables summarize the

The following methods and assumptions were used by the Company in estimating fair values of other assets and liabilities for disclosure purposes:

Cash and cash equivalents and interest bearing deposits with other banks—For these short-term instruments, the carrying amount is a reasonable estimate of fair value.

Securities held-to-maturity—The Company obtains fair value measurements from an independent pricing service. Management reviews the procedures used by the third party, including significant inputs used in the fair value calculations. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. When market quotes are not readily accessible or available, alternative approaches are utilized, such as matrix or model pricing.

Restricted stock—The fair value has been determined to approximate cost.

Loans held for sale—The fair value of loans held for sale are based on quoted market prices, where available, and determined by discounted estimated cash flows using interest rates approximating the Company’s current origination rates for similar loans adjusted to reflect the inherent credit risk.

Loan and lease receivables, net—For certain variable rate loans that reprice frequently and with no significant changes in credit risk, fair value is estimated at carrying value. The fair value of other types of loans is estimated using an exit price notion. It is estimated by discounting future cash flows, using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Deposits—The fair value of demand deposits, savings accounts, and certain money market deposits is the amount payable on demand at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated by discounting future cash flows, using rates currently offered for deposits of similar remaining maturities.

Paycheck Protection Program Liquidity Facility—The carrying amount approximates fair value.

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

Federal Home Loan Bank advances—The fair value of FHLB advances is estimated by discounting the agreements based on maturities using rates currently offered for FHLB advances of similar remaining maturities adjusted for prepayment penalties that would be incurred if the borrowings were paid off on the measurement date.

Securities sold under agreements to repurchase—The carrying amount approximates fair value due to maturities of less than ninety days.

Subordinated notes—The fair value is based on available market prices.

Junior subordinated debentures—The fair value of junior subordinated debentures, in the form of trust preferred securities, is determined using rates currently available to the Company for debt with similar terms and remaining maturities.

Accrued interest receivable and payable—The carrying amount approximates fair value.

Commitments to extend credit and letters of credit—The fair values of these off-balance sheet commitments to extend credit and commercial and letters of credit are not considered practicable to estimate because of the lack of quoted market prices and the inability to estimate fair value without incurring excessive costs.

The estimated fair values of financial instruments not carried at fair value and levels within the fair value hierarchy are as follows:

Note 16—Derivative Instruments and Hedge Activities

As required by ASC 815, the Company records all derivatives on the Condensed Consolidated Statements of Financial Condition at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. The Company records derivative assets and derivative liabilities on the Condensed Consolidated Statements of Financial Condition within accrued interest receivable and other assets and accrued interest payable and other liabilities, respectively. The following tables present the fair value of the Company’s derivative financial instruments and classification on the Condensed Consolidated Statements of Financial Condition as of March 31, 2022 and December 31, 2021:

Total derivatives	$	945,414	$	29,113	$	(7,475	)	$	847,447	$	13,375	$	(9,665	)

Interest rate swaps designated as cash flow hedges—Cash flow hedges of interest payments associated with certain other borrowings had notional amounts totaling $450.0 million as of March 31, 2022, and $400.0 million as of December 31, 2021. The Company assesses the effectiveness of each hedging relationship by comparing the changes in fair value of the derivatives hedging instrument with the fair value of the designated hedged transactions. As of March 31, 2022, the cash flow hedges aggregating $450.0 million in notional amounts are comprised of five forward starting pay fixed interest rate swaps totaling $350.0 million, of which one for $50.0 million is effective in September 2022; two totaling $200.0 million are effective in March 2023; one for $50.0 million is effective in May 2023; and one for $50.0 million is effective in September 2023.

Included in other comprehensive income is the remaining balance related to previously terminated interest rate swaps designated as cash flow hedges of $97,000 as of March 31, 2022 and $199,000 as of December 31, 2021. These are amortized over the original life of the cash flow hedge. Interest recorded on these swap transactions was $210,000 and $21,000 during the three months ended March 31, 2022, and 2021, respectively, and is reported as a component of interest expense on other borrowings. As of March 31, 2022, the Company estimates $1.2 million of the unrealized gain to be reclassified as a decrease to interest expense during the next twelve months.

The following table reflects the cash flow hedges as of March 31, 2022:

Notional amounts	$	450,000
Derivative assets fair value		21,782
Derivative liabilities fair value		—
Weighted average maturity	4.7 years

The weighted average pay rates of the swaps are 1.04% as of March 31, 2022, and weighted average receive rates are determined at the time the forward swaps become effective. The weighted average receive rate for the effective hedge of $100.0 million is 0.20% as of March 31, 2022.

Interest rate swaps	$	17,643	$	(210	)	$	—	$	4,992	$	(21	)	$	—

Derivatives not designated as hedges are not speculative and are used to manage the Company’s exposure to interest rate movements and other identified risks but do not meet the strict hedge accounting requirements and/or the Company has not elected to apply hedge accounting. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings.

Other interest rate derivatives—The total combined notional amount was $488.1 million as of March 31, 2022 with maturities ranging from April 2022 to March 2032. The fair values of the interest rate derivative agreements are reflected in other assets and other liabilities with corresponding gains or losses reflected in non-interest income. During the three months ended March 31, 2022 and 2021, there were $1.1 million and $42,000 of net transaction fees, respectively, included in other non-interest income, related to these derivative instruments.

These instruments are inherently subject to market risk and credit risk. Market risk is associated with changes in interest rates and credit risk relates to the Company’s risk of loss when the counterparty to a derivative contract fails to perform according to the terms of the agreement. Market and credit risks are managed and monitored as part of the Company’s overall asset-liability management process. The credit risk related to derivatives entered into with certain qualified borrowers is managed through the Company’s loan underwriting process. The Company’s loan underwriting process also approves the Bank’s swap counterparty used to mirror the borrowers’ swap. The Company has a bilateral agreement with each swap counterparty that provides that fluctuations in derivative values are to be fully collateralized with either cash or securities.

The following table reflects other interest rate derivatives as of March 31, 2022:

Notional amounts	$	488,064
Derivative assets fair value		7,331
Derivative liabilities fair value		7,474
Weighted average pay rates		4.13	%
Weighted average receive rates		4.33	%
Weighted average maturity	5.9 years

Other credit derivatives— The Company has entered into risk participation agreements with counterparty banks to assume a portion of the credit risk related to borrower transactions. The credit risk related to these other credit derivatives is managed through the Company’s loan underwriting process. The total notional amount was $7.4 million and $7.6 million as of March 31, 2022 and December 31, 2021, respectively. The fair value of the other credit derivatives is reflected in other liabilities with corresponding gains or losses reflected in non-interest income.

The Company has agreements with its derivative counterparties that contain a cross-default provision under which if the Company defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. The Company also has agreements with certain derivative counterparties that contain a provision where if the Company fails to maintain its status as a well or adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations resulted in a net asset position.

Note 17 – Share-Based Compensation

In June 2017, the Company's Board of Directors adopted, and the Company's stockholder approved, the 2017 Omnibus Incentive Compensation Plan (the “Omnibus Plan”). The Omnibus Plan provides for the grant of stock options, stock appreciation rights, restricted stock, restricted stock units, dividend equivalent rights and other equity-based, equity-related or cash-based awards. A total of 1,550,000 shares of our common stock have been reserved for issuance under the Omnibus Plan. As of March 31, 2022, there were 400,377 shares available for future grants under the Omnibus Plan.

The Company primarily grants time-based restricted share awards that vest over a one to four year period, subject to continued employment. The Company also grants performance-based restricted share awards. The number of shares which may be earned under the award is dependent upon the Company’s return on average assets, weighted equally over a three-year period and measured against a peer group consisting of publicly-traded bank holding companies. Results will be measured cumulatively at the end of the three years. Any earned shares will vest on the third anniversary of the grant date.

During 2022, the Company granted 289,277 shares of restricted common stock, par value $0.01 per share. Of this total, 166,290 restricted shares will vest ratably over four years on each anniversary of the grant date, 69,910 restricted shares will vest ratably over three years on each anniversary of the grant date, and 10,589 restricted shares will cliff vest on the third anniversary of the grant date. In addition, 42,488 performance-based restricted shares were included in the 2022 grant which have a period ending December 31, 2024.

The following table discloses the changes in restricted shares for the three months ended March 31, 2022:

Forfeited		(169	)		18.33
Ending balance outstanding at March 31, 2022		756,457		$	22.13

A total of 75,171 restricted shares vested during the three months ended March 31, 2022. A total of 148,577 restricted shares vested during the year ended December 31, 2021. The fair value of restricted shares that vested during the three months ended March 31, 2022 was $2.0 million. The fair value of restricted shares that vested during the year ended December 31, 2021 was $3.4 million.

The Company recognizes share-based compensation based on the estimated fair value of the restricted stock at the grant date. Share-based compensation expense is included in non-interest expense in the Condensed Consolidated Statements of Operations.

The fair value of the unvested restricted stock awards at March 31, 2022 was $20.2 million.

In October 2014, the Company adopted the Byline Bancorp, Inc. Equity Incentive Plan (“BYB Plan”). The maximum number of shares available for grants under this plan was 2,476,122 shares. The Company granted 1,846,968 options to purchase shares under this plan. In June 2017, the Board of Directors terminated the BYB Plan and no future grants can be made under this plan. Options to purchase a total of 1,080,554 shares remain outstanding under the BYB Plan at March 31, 2022.

The types of stock options granted under the BYB Plan were Time Options and Performance Options. The exercise price of each option is equal to the fair value of the stock as of the date of grant. These option awards have vesting periods ranging from one to five years and have 10-year contractual terms. Stock volatility was computed as the average of the volatilities of peer group companies. All outstanding stock options were fully vested and exercisable at March 31, 2022.

The fair values of the stock options were determined using the Black-Scholes-Merton model for Time Options and a Monte Carlo simulation model for Performance Options.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following is a discussion and analysis of Byline Bancorp, Inc.’s financial condition and results of operations and should be read in conjunction with our Unaudited Interim Condensed Consolidated Financial Statements and notes thereto included elsewhere in this report. The words “the Company,” “we,” “Byline,” “management,” “our” and “us” refer to Byline Bancorp, Inc. and its consolidated subsidiaries, unless we indicate otherwise. In addition to historical information, this discussion contains forward looking statements that involve risks, uncertainties and assumptions that could cause actual results to differ materially from management’s expectations. Factors that could cause such differences are discussed in the sections entitled “Special Note Regarding Forward Looking Statements” and “Risk Factors”. Byline assumes no obligation to update any of these forward looking statements.

Forward-Looking Statements

Statements contained in this report and in other documents we file with or furnish to the Securities and Exchange Commission (“SEC”) that are not historical facts may constitute “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Any statements about our expectations, beliefs, plans, strategies, predictions, forecasts, objectives or assumptions of future events or performance are not historical facts and may be forward-looking.

Our ability to predict results or the actual effects of future plans, strategies or events is inherently uncertain. Factors which could cause actual results or conditions to differ materially from those reflected in forward-looking statements include:

• the current and potential disruption to and impact on our business, capital, employees, financial condition, liquidity, operations, prospects, and results of operations, including a decrease in revenue and an increase in expenses, as well as the trading price of our common stock as a result of the economic and other consequences, including the severity and duration, of the pandemic caused by the novel coronavirus SARS-CoV-2 (“COVID-19”);

• uncertainty regarding domestic, foreign, and geopolitical developments and the United States and global economic outlook that may impact market conditions or affect demand for certain banking products and services, including, but not limited to as a result of the disruption of global, national, state, and local economies associated with the COVID-19 pandemic, as well as federal, state, and local government responses thereto, and the impact on our customers, which could impair the ability of our borrowers to repay outstanding loans and leases, impair collateral values and further increase our allowance for loan and lease losses, as well as result in possible asset impairment charges;

• unforeseen credit quality problems or changing economic conditions that could result in charge-offs greater than we have anticipated in our allowance for loan and lease losses or changes in the value of our investments;

• commercial real estate market conditions in the Chicago metropolitan area and southern Wisconsin;

• deterioration in the financial condition of our borrowers resulting in significant increases in our loan and lease losses and provisions for those losses and other related adverse impacts to our results of operations and financial condition;

• estimates of fair value of certain of our assets and liabilities, which could change in value significantly from period to period;

• competitive pressures in the financial services industry in our market areas relating to both pricing and loan and lease structures, which may impact our growth rate;

• unanticipated developments in pending or prospective loan and/or lease transactions or greater-than-expected pay downs or payoffs of existing loans and leases;

• inaccurate information and assumptions in our analytical and forecasting models used to manage our balance sheet;

• unanticipated changes in monetary policies of the Federal Reserve or significant adjustments in the pace of, or market expectations for, future interest rate changes;

• availability of sufficient and cost-effective sources of liquidity, funding, and capital as and when needed;

• our ability to attract, retain or the loss of key personnel or an inability to recruit appropriate talent cost-effectively;

• adverse effects on our information technology systems resulting from failures, human error or cyberattack, including the potential impact of disruptions or security breaches at our third-party service providers, any of which could result in an information or security breach, the disclosure or misuse of confidential or proprietary information, significant legal and financial losses and reputational harm;

• greater-than-anticipated costs to support the growth of our business, including investments in new lines of business, products and services, or technology, process improvements or other infrastructure enhancements, or greater-than-anticipated compliance or regulatory costs and burdens;

• the impact of possible future acquisitions, if any, including the costs and burdens of integration efforts;

• the ability of the Company to receive dividends from Byline Bank;

• legislative or regulatory changes, particularly changes in regulation of financial services companies and/or the products and services offered by financial services companies;

• changes in Small Business Administration (“SBA”) and U.S. Department of Agriculture (“USDA”) U.S. government guaranteed lending rules, regulations, loan and lease products and funding limits, including specifically the SBA Section 7(a) program, as well as changes in SBA or USDA standard operating procedures or changes to the status of Byline Bank as an SBA Preferred Lender;

• changes in accounting principles, policies and guidelines applicable to bank holding companies and banking generally;

• the impact of a possible change in the federal or state income tax rates on our deferred tax assets and provision for income tax expense;

• our ability to implement our growth strategy, including via acquisitions;

• the possibility that any of the anticipated benefits of acquisitions will not be realized or will not be realized within the expected time period;

• the risk that the integration of acquisition operations will be materially delayed or will be more costly or difficult than expected;

• the effect of mergers on customer relationships and operating results; and

• other risks detailed from time to time in filings we make with the SEC.

These risks and uncertainties should be considered in evaluating any forward-looking statements, and undue reliance should not be placed on such statements. Forward looking statements speak only as of the date they are made. You should also consider the risks, assumptions and uncertainties set forth in the “Risk Factors” section of this Form 10-Q, in our Annual Report on Form 10-K for the year ended December 31, 2021, that was filed with the SEC on March 7, 2022, as well as those set forth in the reports we file with the SEC. We assume no obligation to update any of these statements in light of new information, future events or otherwise unless required under the federal securities laws.

Overview

Our business

We are a bank holding company headquartered in Chicago, Illinois and conduct all our business activities through our subsidiary, Byline Bank, a full service commercial bank, and Byline Bank’s subsidiaries. Through Byline Bank, we offer a broad range of banking products and services to small and medium sized businesses, commercial real estate and financial sponsors and to consumers who generally live or work near our branches. We also offer online accounting opening to consumer customers through our website and provide trust and wealth management services to our customers. In addition to our traditional commercial banking business, we provide small ticket equipment leasing solutions through Byline Financial Group, a wholly-owned subsidiary of Byline Bank, headquartered in Bannockburn, Illinois, with sales offices in Illinois, and sales representatives in Illinois, Florida, Michigan, New Jersey, and New York. We also participate in U.S. government guaranteed lending programs and originate U.S. government guaranteed loans. Byline Bank was the fifth most active originator of Small Business Administration (“SBA”) loans in the country and the most active SBA lender in Illinois, as reported by the SBA for the quarter ended March 31, 2022.

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans and lease receivables, including accretion income on loans, investment securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of non-interest income, consisting primarily of income from fees and service charges on deposits, loan servicing revenue, wealth management and trust income, ATM and interchange fees, and net gains on sales of investment securities and loans. Other factors contributing to our results of operations include our provisions for loan and lease

losses, provision for income taxes, and non-interest expenses, such as salaries and employee benefits, occupancy and equipment expenses and other miscellaneous operating costs.

We reported consolidated net income of $22.3 million for the three months ended March 31, 2022, compared to net income of $21.8 million for the three months ended March 31, 2021, an increase of $513,000. The increase in net income was attributable to a $2.1 million increase in net interest income and a $3.7 million increase in non-interest income, offset by a $5.7 million increase in non-interest expense. The increase in net interest income during the three months ended March 31, 2022 was primarily a result of an increase in average interest-earning assets. The increase in non-interest income was primarily driven by gains on the sales of loans. The increase in non-interest expense was mainly due to an increase in salaries and employee benefits as a result of new hires.

Dividends declared and paid on preferred shares were $196,000 for three months ended March 31, 2022 and 2021. Dividends declared on common shares were $3.4 million and $2.3 million for the three months ended March 31, 2022 and 2021, respectively. Dividends paid on common shares were $3.3 million and $2.3 million for the three months ended March 31, 2022 and 2021, respectively. For the three months ended March 31, 2022 and 2021, net income available to common stockholders was $22.1 million, or $0.60 per basic and $0.58 per diluted common share, and $21.6 million, or $0.57 per basic and $0.56 per diluted common share, respectively. Our results of operations for the three months ended March 31, 2022 and 2021, yielded an annual return on average assets of 1.35% and 1.34% and a return on average stockholders’ equity of 10.87% and 10.96%, respectively.

As of March 31, 2022, we had consolidated total assets of $6.8 billion, total gross loans and leases outstanding of $4.8 billion, total deposits of $5.5 billion, and total stockholders’ equity of $788.7 million.

Critical Accounting Policies and Significant Estimates

Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America (“GAAP”) and to general practices within the Banking industry. To prepare financial statements and interim financial statements in conformity with GAAP, management makes estimates, assumptions and judgments based on available information. These estimates, assumptions and judgments affect the amounts reported in the financial statements and accompanying notes; and are based on information available as of the date of the financial statements. As this information changes, actual results could differ from the estimates, assumptions and judgments reflected in the financial statements. In particular, management has identified several accounting policies that, due to the estimates, assumptions and judgements inherent in those policies, are critical in understanding our financial statements.

These critical accounting policies and estimates include (i) acquisition‑related fair value computations, (ii) the carrying value of loans and leases, (iii) determining the provision and allowance for loan and lease losses, (iv) the valuation of intangible assets such as goodwill, servicing assets and core deposit intangibles, (v) the determination of fair value for financial instruments, including other-than-temporary-impairment losses, (vi) the valuation of real estate held for sale, and (vii) the valuation of or recognition of deferred tax assets and liabilities.

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, permits us an extended transition period for complying with new or revised accounting standards affecting public companies. We have elected to take advantage of this extended transition period, which means that the financial statements included in this report, as well as any financial statements that we file in the future, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as we remain an emerging growth company or until we affirmatively and irrevocably opt out of the extended transition period provided for under the JOBS Act. We will remain an emerging growth company until the end of the fiscal year following the fifth anniversary of the completion of our initial public offering, which is December 31, 2022.

The following is a discussion of the critical accounting policies and significant estimates that require us to make complex and subjective judgments. Additional information about these policies can be found in Note 1 of our audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2021, that we filed with the SEC on March 7, 2022.

Business Combinations

We account for business combinations under the acquisition method of accounting in accordance with ASC 805. We recognize the fair value of the assets acquired and liabilities assumed as of the date of acquisition, with any excess of the fair value of consideration provided over the fair value of the identifiable net tangible and intangible assets acquired recorded as goodwill. Transaction costs are expensed as incurred. Application of the acquisition method requires extensive use of accounting estimates and judgements to determine the fair values of the identifiable assets acquired and liabilities assumed at the acquisition date.

In accordance with ASC 805, the acquiring company retains the right to make appropriate adjustments to the assets and liabilities of the acquired entity for information obtained during the measurement period about facts and circumstances that existed as of the acquisition date. The measurement period ends as of the earlier of (i) one year from the acquisition date or (ii) the date when the acquirer receives the information necessary to complete the business combination accounting.

Carrying Value of Loans and Leases

Our accounting methods for loans and leases differ depending on whether they are new or acquired loans and leases; and for acquired loans, whether the loans were acquired at a discount as a result of credit deterioration since the date of origination.

Originated Loans and Leases

We account for originated loans and leases and purchased loans and leases not acquired through business combinations as originated loans and leases. The new loans that management has the intent and ability to hold for the foreseeable future are reported at their outstanding principal balances net of any allowance for loan and lease losses, unamortized deferred fees and costs and unamortized premiums or discounts. The net amount of non-refundable loan origination fees and certain direct costs associated with the lending process are deferred and amortized to interest income over the contractual lives of the new loans using methods that approximate the level yield method. Discounts and premiums are amortized or accreted to interest income over the estimated term of the new loans using methods that approximate the effective yield method. Interest income on new loans is accrued based on the unpaid principal balance outstanding. Additionally, once an acquired non-impaired loan reaches its contractual maturity date, it is re-underwritten, and if renewed, it is classified as an originated loan.

Acquired Loans and Leases

Acquired loans and leases are recorded at fair value as of the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either acquired impaired or acquired non‑impaired. Acquired impaired loans reflect evidence of credit deterioration since origination for which it is probable that all contractually required principal and interest will not be collected by us. Subsequent to acquisition, we periodically update for changes in cash flow expectations, which are reflected in interest income over the life of the loan as accretable yield. Any subsequent decreases in expected cash flow attributable to credit deterioration are recognized by recording a provision for loan losses.

For acquired non‑impaired loans and leases, the excess or deficit of the loan and lease principal balance over the fair value is recorded as a discount or premium at acquisition and is accreted through interest income over the life of the loan or lease. Subsequent to acquisition, these loans and leases are evaluated for credit deterioration and a provision for loan and lease losses would be recorded when probable loss is incurred. These loans and leases are evaluated for impairment consistent with originated loans and leases.

Provision and Allowance for Loan and Lease Losses

The provision for loan and lease losses reflects the amount required to maintain the allowance for loan and lease losses (“ALLL”) at an appropriate level based upon management’s evaluation of the adequacy of general and specific loss reserves.

The ALLL is maintained at a level that management believes is appropriate to provide for known and inherent incurred loan and lease losses as of the dates of the Consolidated Statements of Financial Condition, and we have established methodologies for the determination of its adequacy. The methodologies are set forth in a formal policy and take into consideration the need for an overall general valuation allowance as well as specific allowances that are determined on an individual loan basis. We increase our ALLL by charging provisions for probable losses against our income and decreased by charge‑offs, net of recoveries.

The evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. While management uses available information to recognize losses on loans and leases, changes in economic or other conditions may necessitate revision of the estimate in future periods.

The ALLL is maintained at a level management believes is sufficient to provide for probable losses based upon an ongoing review of the originated and acquired non‑impaired loan and lease portfolios by portfolio category, which include consideration of actual loss experience, peer loss experience, changes in the size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of prevailing economic conditions.

For acquired impaired loans, a specific valuation allowance is established when it is probable that we will be unable to collect all of the cash flows expected at acquisition, plus the additional cash flows expected to be collected arising from changes in estimates after acquisition.

The originated and non‑impaired acquired loans have limited delinquency and credit loss history and have not yet exhibited an observable loss trend. The credit quality of loans in these loan portfolios are impacted by delinquency status and debt service coverage generated by the borrowers’ businesses and fluctuations in the value of real estate collateral.

Acquired non‑impaired loans and originated loans are considered impaired when, based on current information and events, it is probable that we will be unable to collect the scheduled payments of principal or interest when due, according to the contractual terms of the loan agreements. All acquired non‑impaired loans and originated loans of $100,000 or greater with an internal risk rating of substandard or below and on non-accrual, as well as loans classified as troubled debt restructurings (“TDR”), are reviewed individually for impairment on a quarterly basis.

Goodwill and Other Intangible Assets

Goodwill. Goodwill represents the excess of the purchase consideration over the fair value of net assets acquired in connection with our recapitalization and acquisitions using the acquisition method of accounting. Goodwill is not amortized but is periodically evaluated for impairment under the provisions of ASC Topic 350, Intangibles—Goodwill and Other (“ASC 350”).

Impairment testing is performed using either a qualitative or quantitative approach at the reporting unit level. Our goodwill is allocated to Byline Bank, which is our only applicable reporting unit for the purposes of testing goodwill for impairment. We have selected November 30 as the date to perform the annual goodwill impairment test. Additionally, we perform a goodwill impairment evaluation on an interim basis when events or circumstances indicate impairment potentially exists.

Servicing Assets. Servicing assets are recognized separately when they are acquired through sales of loans or when the rights to service loans are purchased. When loans are sold with servicing rights retained, servicing assets are recorded at fair value in accordance with ASC Topic 860, Transfers and Servicing (“ASC 860”). Fair value is based on market prices for comparable servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The fair value of servicing rights is highly sensitive to changes in underlying assumptions. Changes in secondary market premiums and prepayment speed assumptions have the most significant impact on the fair value of servicing rights. See Note 6 and Note 15 of our Unaudited Interim Condensed Consolidated Financial Statements as of March 31, 2022, included in this report, for additional information.

Core Deposit Intangible Assets. Other intangible assets primarily consist of core deposit intangible assets. In valuing core deposit intangibles, we consider variables such as deposit servicing costs, attrition rates and market discount rates. Core deposit intangibles are reviewed annually, or more frequently when events or changes in circumstances occur that indicate that their carrying values may not be recoverable. If the recoverable amount of the core deposit intangibles is determined to be less than its carrying value, we would then measure the amount of impairment based on an estimate of the fair value at that time. We also evaluate whether the events or circumstances have occurred that warrant a revision to the remaining useful lives of intangible assets. In cases where a revision is deemed appropriate, the remaining carrying amounts of the intangible assets are amortized over the revised remaining useful life. Core deposit intangibles are currently amortized over an approximate ten-year period.

Customer Relationship Intangible. Other intangible assets also include our customer relationship intangible asset. In valuing our customer relationship intangibles, we consider variables such as assets under administration, attrition rates, and fee structure. Customer relationship intangibles are currently amortized over a 12-year period.

Fair value of Financial Instruments

ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received to sell a financial asset or paid to transfer a financial liability in an orderly transaction between market participants at the measurement date.

The degree of management judgment involved in determining the fair value of assets and liabilities is dependent upon the availability of quoted market prices or observable market parameters. For financial instruments that trade actively and have quoted market prices or observable market parameters, there is minimal subjectivity involved in measuring fair value. When observable market prices and parameters are not available, management judgment is necessary to estimate fair value. In addition, changes in market conditions may reduce the availability of quoted prices or observable data. For example, reduced liquidity in the capital markets or changes in secondary market activities could result in observable market inputs becoming unavailable. Therefore, when market data is not available, we would use valuation techniques requiring more management judgment to estimate the appropriate fair value measurement.

See Note 15 of our Unaudited Interim Condensed Consolidated Financial Statements as of March 31, 2022, included in this report, for a complete discussion of our use of fair value of financial assets and liabilities and their related measurement practices.

Valuation of Real Estate Held for Sale

Other Real Estate Owned (“OREO”). OREO includes real estate assets that have been acquired through, or in lieu of, loan foreclosure or repossession and are to be sold. OREO assets are initially recorded at fair value, less estimated costs to sell, of the collateral of the loan, on the date of foreclosure or repossession, establishing a new cost basis. Adjustments that reduce loan balances to fair value at the time of foreclosure or repossession are recognized as charge‑offs in the allowance for loan and lease losses. Positive adjustments, if any, at the time of foreclosure or repossession are recognized in non‑interest expense. After foreclosure or repossession, management periodically obtains new valuations and real estate or other assets may be adjusted to a lower carrying amount, determined by the fair value of the asset, less estimated costs to sell. Any subsequent write‑downs are recorded as a decrease in the asset and charged against other real estate owned valuation adjustments, included within non-interest expense. Operating expenses of such properties, net of related income, are included in non‑interest expense, and gains and losses on their disposition are included in non‑interest expense. Any losses on the sales of other real estate owned properties are recognized immediately. OREO is recorded net of participating interests sold.

Assets Held for Sale. Assets held for sale consist of former branch locations and real estate purchased for expansion. Assets are considered held for sale when management has approved a plan to sell the assets following a branch closure or other events. The properties are being actively marketed and transferred to assets held for sale based at the lower of its carrying value or its fair value, less estimated costs to sell. Adjustments to reduce the asset balances to fair value are recorded at the time of transfer and are recognized through a charge against

income. An assessment of the recoverability of other long-lived assets associated with all branches is periodically performed, resulting in impairment losses which are reflected in other non-interest expense.

Income Taxes

We use the asset and liability method to account for income taxes. The objective of the asset and liability method is to establish deferred tax assets and liabilities for the temporary differences between the financial reporting basis and the income tax basis of our assets and liabilities at enacted tax rates expected to be in effect when such amounts are realized or settled. Our annual tax rate is based on our income, statutory tax rates and available tax planning opportunities. Tax laws are complex and subject to different interpretations by the taxpayer and respective governmental taxing authorities. Significant judgment is required in determining tax expense and in evaluating tax positions, including evaluating uncertainties.

Deferred income tax assets represent amounts available to reduce income taxes payable on taxable income in future years. Such assets arise because of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating loss carryforwards. We review our deferred tax positions quarterly for changes which may impact realizability. We evaluate the recoverability of these future tax deductions by assessing the adequacy of future expected taxable income from all sources, including reversal of taxable temporary differences, forecasted operating earnings and available tax planning strategies. We use short and long‑range business forecasts to provide additional information for its evaluation of the recoverability of deferred tax assets. It is our policy to recognize interest and penalties associated with uncertain tax positions, if applicable, as components of non‑interest expense.

A deferred tax valuation allowance is established to reduce the net carrying amount of deferred tax assets if it is determined to be more likely than not that all or some of the deferred tax asset will not be realized. See Note 12 of the notes to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2021, for further information on income taxes.

Refer to Note 2 of our Unaudited Interim Condensed Consolidated Financial Statements as of March 31, 2022, included in this report, for a description of recent accounting pronouncements, including the effective dates of adoption and anticipated effects on our results of operations and financial condition.

Primary Factors Used to Evaluate Our Business

As a financial institution, we manage and evaluate various aspects of both our results of operations and our financial condition. We evaluate the levels and trends of the line items included in our consolidated balance sheet and income statement as well as various financial ratios that are commonly used in our industry. We analyze these ratios and financial trends against our own historical performance, our budgeted performance and the final condition and performance of comparable financial institutions in our region. Comparison of our financial performance against other financial institutions is impacted by the accounting for acquired non‑impaired and acquired impaired loans.

These factors and metrics described in this report may not provide an appropriate basis to compare our results or financial condition to the results or financial condition of other financial services companies, given our limited operating history and strategic acquisitions since our recapitalization.

Results of Operations

Overview

Our results of operations depend substantially on net interest income, which is the difference between interest income on interest-earning assets, consisting primarily of interest income on loans and lease receivables, including accretion income on loans, investment securities and other short-term investments, and interest expense on interest-bearing liabilities, consisting primarily of deposits and borrowings. Our results of operations are also dependent upon our generation of non-interest income, consisting primarily of income from fees and service charges on deposits, loan servicing revenue, wealth management and trust income, ATM and interchange fees, and net gains on sales of investment securities and loans. Other factors contributing to our results of operations include our provisions for loan and lease losses, provision for income taxes, and non-interest expenses, such as salaries and employee benefits, occupancy and equipment expenses, and other miscellaneous operating costs.

We reported consolidated net income of $22.3 million for the three months ended March 31, 2022 compared to net income of $21.8 million for the three months ended March 31, 2021, an increase of $513,000. The increase in net income was primarily attributable to a $2.1 million increase in net interest income, and a $3.7 million increase in non-interest income. These were offset by a $5.7 million increase in non-interest expense and a $628,000 increase in the provision for loan and lease losses.

The increase in net interest income during the three months ended March 31, 2022 was mainly a result of increased average loan and leases balances and decrease in borrowed funds due to deposit growth. The increase in provision for loan and lease losses was mainly attributable to increases in qualitative factors and loan and lease portfolio growth. The increase in non-interest income was principally driven by higher net gains on sales of loans and increases in swap income. The increase in non-interest expense was mostly due to an increase in salaries and employee benefits.

Net income available to common stockholders was $22.1 million, or $0.60 per basic and $0.58 per diluted common share, for the three months ended March 31, 2022 compared to $21.6 million, or $0.57 per basic and $0.56 per diluted common share, for the three months ended March 31, 2021. Dividends on preferred shares were $196,000 for the three months ended March 31, 2022 and 2021.

Our annualized return on average assets was 1.35% for the three months ended March 31, 2022 compared to 1.34% for the three months ended March 31, 2021. Our annualized return on average stockholders’ equity was 10.87% for the three months ended March 31, 2022 compared to 10.96% for the three months ended March 31, 2021. Our efficiency ratio was 54.96% for the three months ended March 31, 2022 compared to 51.25% for the three months ended March 31, 2021.

Net Interest Income

Net interest income, representing interest income less interest expense, is a significant contributor to our revenues and earnings. We generate interest income from interest and dividends on interest-earning assets, which include loans, leases and investment securities we own. We incur interest expense from interest paid on interest-bearing liabilities, which include interest-bearing deposits, subordinated debt, Federal Home Loan Bank advances, junior subordinated debentures and other borrowings. To evaluate net interest income, we measure and monitor (i) yields on our loans and other interest-earning assets, (ii) the costs of our deposits and other funding sources, (iii) our net interest spread, and (iv) our net interest margin. Net interest spread is the difference between rates earned on interest-earning assets and rates paid on interest-bearing liabilities. Net interest margin is calculated as the annualized net interest income divided by average interest-earning assets. Because non-interest-bearing sources of funds, such as non-interest-bearing deposits and stockholders’ equity, also fund interest-earning assets, net interest margin includes the benefit of these non-interest-bearing sources.

We also recognize income from the accretable discounts associated with the purchase of interest-earning assets. Because of our recapitalization and bank acquisitions, we derive a portion of our interest income from the accretable discounts on acquired loans. The accretion is generally recognized over the life of the loan and is impacted by changes in expected cash flows on the loan. This accretion will continue to have an impact on our net interest income as long as loans acquired with a discount at acquisition represent a meaningful portion of our interest-earning assets. As of March 31, 2022, acquired loans with evidence of credit deterioration accounted for under ASC Topic 310-30, Accounting for Purchased Loans with Deteriorated Credit Quality, represented 2.5% of our total loan portfolio compared to 2.8% at December 31, 2021.

Changes in the market interest rates we earn on interest-earning assets or pay on interest-bearing liabilities, as well as the volume and types of interest-earning assets, interest-bearing and non-interest-bearing liabilities, are usually the largest drivers of periodic changes in net interest spread, net interest margin and net interest income. In addition, our interest income includes the accretion of the discounts on our acquired loans, which will also affect our net interest spread, net interest margin and net interest income.

The following tables present, for the periods indicated, information about (i) average balances, the total dollar amount of interest income from interest-earning assets and the resultant average yields; (ii) average balances, the total dollar amount of interest expense on interest-bearing liabilities and the resultant average rates; (iii) net interest income; (iv) the interest rate spread; and (v) the net interest margin. Yields have been calculated on a pre-tax basis (dollars in thousands).

(1) Loan and lease balances are net of deferred origination fees and costs and initial direct costs. Non-accrual loans and leases are included in total loan and lease balances.

(2) Interest income and rates include the effects of a tax equivalent adjustment to adjust tax-exempt investment income on tax-exempt investment securities to a fully taxable basis, assuming a federal income tax rate of 21%.

(3) Represents the average rate earned on interest-earning assets minus the average rate paid on interest-bearing liabilities.

(4) Represents net interest income (annualized) divided by total average interest-earning assets.

(5) Average balances are average daily balances.

Increases and decreases in interest income and interest expense result from changes in average balances (volume) of interest-earning assets and interest-bearing liabilities, as well as changes in average interest rates. The following table sets forth the effects of changing rates and volumes on our net interest income during the periods shown. Information is provided with respect to (i) effects on interest income attributable to changes in volume (changes in volume multiplied by prior rate) and (ii) effects on interest income attributable to changes in rate (changes in rate multiplied by prior volume). Changes applicable to both volume and rate have been allocated to volume. Yields have been calculated on a pre-tax basis. The table below is a summary of increases and decreases in interest income and interest expense resulting from changes in average balances (volume) and changes in average interest rates (dollars in thousands):

(1) Includes loans and leases on non-accrual status.

Net interest income for the three months ended March 31, 2022 was $58.7 million compared to $56.6 million during the same period in 2021, an increase of $2.1 million, or 3.7%. Interest income increased $1.7 million for the three months ended March 31, 2022 compared to the same period in 2021 primarily a result of increased average balance on loans and leases, offset by a decrease in PPP interest and fee income. Interest expense decreased by $437,000 for the three months ended March 31, 2022 compared to the same period in 2021 mostly due to decreases in the average rates paid on deposits.

The net interest margin for the three months ended March 31, 2022 was 3.81%, an increase of four basis points compared to 3.77% for the three months ended March 31, 2021. The primary drivers of the increase for the three month period was an increase in average interest earning assets.

Net loan accretion income was $1.5 million for the three months ended March 31, 2022 compared to $2.0 million for the three months ended March 31, 2021, a decrease of $492,000, or 25.0%. Total net loan accretion on acquired loans contributed 10 basis points to the net interest margin for the three months ended March 31, 2022 compared to 13 basis points for the three months ended March 31, 2021. We expect net loan accretion to continue to decline and estimate $879,000 in projected loan accretion for the remainder of 2022.

Provision for Loan and Lease Losses

The provision for loan and lease losses represents a charge to earnings necessary to establish an allowance for loan and lease losses that, in management’s evaluation, is appropriate to provide coverage for probable losses incurred in the loan and lease portfolio. The allowance for loan and lease losses is increased by the provision for loan and lease losses and is decreased by charge-offs, net of recoveries on prior charge-offs.

Provisions for loan and lease losses was $5.0 million and $4.4 million for the three months ended March 31, 2022 and 2021, respectively, an increase of $628,000, or 14.4%.

The ALLL as a percentage of loans and leases increased from 1.21% at December 31, 2021 to 1.24% at March 31, 2022.

Non-Interest Income

Non-interest income was $19.4 million for the three months ended March 31, 2022 compared to $15.7 million for the three months ended March 31, 2021, an increase of $3.7 million, or 23.4%. The increase was primarily due to an increase in net gains on sales of loans and increased swap income, offset by decreases to net realized gains on securities available-for-sale.

All values are in US Dollars.

Fees and service charges on deposits represent amounts charged to customers for banking services, such as fees on deposit accounts, and include, but are not limited to, maintenance fees, insufficient fund fees, overdraft protection fees, wire transfer fees, and other charges. Fees and service charges on deposits were $1.9 million and $1.7 million for the three months ended March 31, 2022 and 2021, respectively. Increases are due to increases in deposits.

While portions of the loans that we originate are sold and generate gains on sale revenue, servicing rights for the majority of loans that we sell are retained by us. In exchange for continuing to service loans that have been sold, we receive servicing revenue from a portion of the interest cash flow of the loan. We generated $3.4 million and $2.8 million in loan servicing revenue on the sold portion of the U.S. government guaranteed loans for the three months ended March 31, 2022 and 2021, respectively. At March 31, 2022 and 2021, the outstanding balance of guaranteed loans serviced was $1.7 billion and $1.6 billion, respectively.

Loan servicing asset revaluation represents net changes in the fair value of our servicing assets. Loan servicing asset revaluation had a downward adjustment of $1.2 million for the three months ended March 31, 2022 compared to a downward adjustment of $1.5 million for the three months ended March 31, 2021, a change of $274,000 due to changes in the fair value of the servicing asset.

Change in fair value of equity securities, net, was a decrease of $151,000 compared to a decrease of $206,000 for the three months ended March 31, 2022 and 2021, respectively. The amounts recorded during the periods were driven by market conditions.

Net gains on sales of loans were $10.8 million for the three months ended March 31, 2022 compared to $8.3 million for the three months ended March 31, 2021, an increase of $2.5 million, or 30.1%. We sold $102.3 million of U.S. government guaranteed loans during the three months ended March 31, 2022 compared to $73.9 million during the three months ended March 31, 2021.

Wealth management and trust income represents fees charged to customers for investment, trust, or wealth management services and are primarily determined by total assets under administration. Wealth management and trust income was $1.0 million for the three months ended March 31, 2022 compared to $768,000 for the three months ended March 31, 2021. Assets under administration were $589.1 million and $588.8 million as of March 31, 2022 and 2021, respectively.

Other non-interest income was $2.6 million for the three months ended March 31, 2022 compared to $1.5 million for the three months ended March 31, 2021, an increase of $1.1 million or 79.6%. The primary driver of the increase was increased customer derivative products income and bank-owned life insurance income.

Non-Interest Expense

Non-interest expense was $44.6 million for the three months ended March 31, 2022 compared to $38.8 million for the three months ended March 31, 2021, an increase of $5.7 million, or 14.7%. The increase was primarily due to an increase in salaries and employee benefits.

The following table presents the major components of our non-interest expense for the periods indicated (dollars in thousands):

	Three Months Ended March 31,					QTD 2022Compared to 2021

Total non-interest expense	$	44,555		$	38,842				14.7	%

All values are in US Dollars.

Salaries and employee benefits, the single largest component of our non-interest expense, totaled $29.0 million for the three months ended March 31, 2022 compared to $21.8 million for the three months ended March 31, 2021, an increase of $7.2 million, or 32.8%. The increase was primarily a result of new hires.

Occupancy and equipment expense was $5.1 million for the three months ended March 31, 2022 compared to $5.8 million for the three months ended March 31, 2021, a decrease of $651,000, or 11.3%. The decreases were a result of lower maintenance and depreciation expenses.

Recapture of loan and lease related expenses was $891,000 for the three months ended March 31, 2022 compared to $951,000 expense for the three months ended March 31, 2021, a decrease of $1.8 million. The change was mainly related to the recapture of government guaranteed loan expenses.

Legal, audit, and other professional fees were $2.6 million for the three months ended March 31, 2022 compared to $2.2 million for the three months ended March 31, 2021, an increase of $386,000, or 17.5%. The increase was driven by increases in professional fees.

Data processing was $3.2 million for the three months ended March 31, 2022, compared to $2.8 million for the three months ended March 31, 2021, an increase of 431,000 or 15.7%. The increase was driven by increased software licensing costs and higher outside services.

Net loss recognized on other real estate owned and other related expenses was $54,000 for the three months ended March 31, 2022, compared to $621,000 for the three months ended March 31, 2021, a decrease of $567,000, or 91.2%. The decrease was primarily due to decreased valuation adjustments on other real estate owned assets.

Other intangible assets amortization expense was $1.6 million for the three months ended March 31, 2022 compared to $1.7 million for the three months ended March 31, 2021, a decrease of $153,000, or 8.7%.

Other non-interest expense was $3.9 million for the three months ended March 31, 2022 compared to $2.4 million for the three months ended March 31, 2021, an increase of $1.6 million or 66.0%. The increase was mostly due to higher provision for unfunded commitments.

Our efficiency ratio was 54.96% for the three months ended March 31, 2022 compared to 51.25% for the three months ended March 31, 2021. The change in our efficiency ratio for the three months ended March 31, 2022 was driven by an increase in our non-interest expense. Our adjusted efficiency ratio was 54.96% for the three months ended March 31, 2022 compared to 50.41% for the three months ended March 31, 2021.

Please refer to the “Reconciliation of Non-GAAP Financial Measures” for a reconciliation of our non-GAAP measures to the most directly comparable GAAP financial measure.

Income Taxes

Our provision for income taxes for the three months ended March 31, 2022 totaled $6.3 million compared to $7.4 million for the three months ended March 31, 2021, a decrease of $1.1 million of 14.6%. The decrease in income tax expense was principally due to income tax benefits related to share-based compensation. Our effective tax rate was 22.0% for the three months ended March 31, 2022 and 25.3% for the three months ended March 31, 2021. We expect our effective tax rate for 2022 to be approximately 25-27%.

Financial Condition

Condensed Consolidated Statements of Financial Condition Analysis

Our total assets increased by $138.5 million, or 2.1%, to $6.8 billion at March 31, 2022 compared to $6.7 billion at December 31, 2021. The increase in total assets includes an increase of $251.9 million, or 5.6%, in loans and leases from $4.5 billion at December 31, 2021 to $4.8 billion at March 31, 2022. Our originated loan and lease portfolio increased by $299.5 million and our acquired loan and lease portfolio decreased by $47.6 million. The increase in our originated portfolio was primarily attributed to organic loan and lease growth, and renewals of acquired non-impaired loans that are now reflected with originated loans, offset by decrease in PPP loans. The decrease in our acquired portfolio was attributed to renewals reflected in originated loans, payoffs, and pay downs during the period.

Total liabilities increased by $186.2 million, or 3.2%, to $6.0 billion at March 31, 2022 compared to $5.9 billion at December 31, 2021. Total deposits increased by $375.1 million, or 7.3%, driven by growth in non-interest-bearing deposits and money market accounts, partly offset by a decrease in time deposits. Other borrowings decreased by $208.3 million, or 40.1%, mainly due to a decrease in FHLB advances.

Investment Portfolio

Our investment securities portfolio consists of securities classified as available-for-sale and held-to-maturity. There were no securities classified as trading in our investment portfolio as of March 31, 2022 or December 31, 2021. All available-for sale securities are carried at fair value and may be used for liquidity purposes should management consider it to be in our best interest. Securities available-for-sale consist primarily of residential mortgage-backed securities, commercial mortgage-backed securities and U.S. government agencies securities.

Securities available-for-sale decreased by $85.2 million, or 5.9%, from $1.5 billion at December 31, 2021 to $1.4 billion at March 31, 2022. The decrease was mainly attributed to decreases in the fair value of available-for-sale securities.

At March 31, 2022, our held-to-maturity securities portfolio consists of obligations of states, municipalities and political subdivisions. We carry these securities at amortized cost. Securities held-to-maturity were $3.9 million at March 31, 2022 and at December 31, 2021.

We had no securities that were classified as having other-than-temporary-impairment (“OTTI”) as of March 31, 2022 or December 31, 2021.

Certain securities have fair values less than amortized cost and, therefore, contain unrealized losses. At March 31, 2022, we evaluated the securities which had an unrealized loss for OTTI and determined all declines in value to be temporary. There were 223 investment securities with unrealized losses at March 31, 2022. We anticipate full recovery of amortized cost with respect to these securities by maturity, or sooner in the event of a more favorable market interest rate environment. We do not intend to sell these securities and it is not more likely than not that we will be required to sell them before recovery of their amortized cost basis, which may be at maturity.

The following table (dollars in thousands) set forth certain information regarding contractual maturities and the weighted average yields of our investment securities as of March 31, 2022. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

As of March 31, 2022, and December 31, 2021, investment securities indexed to LIBOR were $58.3 million and $58.2 million, respectively.

Total non-taxable securities classified as obligations of states, municipalities and political subdivisions were $59.1 million at March 31, 2022, a decrease of $2.6 million from December 31, 2021.

There were no holdings of securities of any one issuer, other than U.S. government-sponsored entities and agencies, with total outstanding balances greater than 10% of our stockholders’ equity as of March 31, 2022 or December 31, 2021.

Restricted Stock

As a member of the Federal Home Loan Bank system, Byline Bank is required to maintain an investment in the capital stock of the FHLB. No market exists for this stock, and it has no quoted market value. The stock is redeemable at par by the FHLB and is, therefore, carried at cost. In addition, Byline Bank owns stock of Bankers’ Bank that was acquired as part of a bank acquisition. The stock is redeemable at par and carried at cost. As of March 31, 2022 and December 31, 2021, we held $14.0 million and $22.0 million, respectively, in FHLB and Bankers’ Bank stock. We evaluate impairment of our investment in FHLB and Bankers’ Bank based on the ultimate recoverability of the par value rather than by recognizing temporary declines in value. We did not identify any indicators of impairment of FHLB and Bankers’ Bank stock as of March 31, 2022 and December 31, 2021.

Loan and Lease Portfolio

Lending-related income is the most important component of our net interest income and is the main driver of the results of our operations. Total loans and leases at March 31, 2022 and December 31, 2021 were $4.8 billion and $4.5 billion, respectively, an increase of $251.9 million, or 5.6%. Originated loans were $4.4 billion at March 31, 2022, an increase of $299.5 million, or 7.3%, compared to $4.1 billion at December 31, 2021. Acquired impaired loans and acquired non-impaired loans and leases were $395.2 million at March 31, 2022, a decrease of $47.6 million, or 10.7%, compared to $442.8 million at December 31, 2021. The increase in our originated portfolio was primarily attributed to organic loan and lease growth, and renewals of acquired non-impaired loans that are now reflected with originated loans. The decrease in our acquired portfolio is attributed to renewals reflected in originated loans, payoffs, and pay downs during the period. PPP loans decreased by $87.5 million during the quarter.

We strive to maintain a relatively diversified loan portfolio to help reduce the risk inherent in concentration in certain types of collateral. Loans, excluding leases, are typically made to real estate, manufacturing, wholesale, retail and service businesses for working capital needs, business expansions and operations. As of March 31, 2022, the loan portfolio included $424.8 million of unguaranteed 7(a) SBA and USDA loans with exposure to the following top three industries: 16.2% accommodation and food services, 15.1% retail trade, and 12.5% manufacturing. The following table shows our allocation of originated, acquired impaired and acquired non-impaired loans and leases as of the dates presented (dollars in thousands):

At March 31, 2022, 44.8% of the loan and lease portfolio bears interest at fixed rates and 55.2% at floating rates. In addition, $1.7 billion,, of the loan and lease portfolio has interest rate floors of which $1.2 billion were at the interest rate floor or had no floor as of March 31, 2022. The expected life of our loan portfolio will differ from contractual maturities because borrowers may have the right to curtail or prepay their loans with or without penalties. Because a portion of the portfolio is accounted for under ASC 310-30, the carrying value is significantly affected by estimates and it is impracticable to allocate scheduled payments for those loans based on those estimates. Consequently, the tables presented include information limited to contractual maturities of the underlying loans. As of March 31, 2022 we had $1.1 billion in loans indexed to LIBOR.

Allowance for Loan and Lease Losses

The ALLL is determined by us on a quarterly basis, although we are engaged in monitoring the appropriate level of the allowance on a more frequent basis. The ALLL reflects management’s estimate of probable incurred credit losses inherent in the loan and lease portfolios. The computation includes elements of judgement and high levels of subjectivity.

Factors considered by us include, but are not limited to, actual loss experience, peer loss experience, changes in size and risk profile of the portfolio, identification of individual problem loan and lease situations which may affect a borrower’s ability to repay, and evaluation of the prevailing economic conditions. Changes in conditions may necessitate revision of the estimate in future periods.

We assess the ALLL based on three categories: (i) originated loans and leases, (ii) acquired non-impaired loans and leases, and (iii) acquired impaired loans with further credit deterioration after the acquisitions or our recapitalization.

Total ALLL was $59.5 million at March 31, 2022 compared to $55.0 million at December 31, 2021, an increase of $4.4 million ,or 8.1%. The increase was primarily due to an increase in general reserves driven by loan and lease growth. Total ALLL to total loans and leases held for investment, net before ALLL, was 1.24% and 1.21% of total loans and leases at March 31, 2022 and December 31, 2021, respectively. The increase was primarily driven by an increase in the provision offset by an increase in loans and leases. As of March 31, 2022, approximately $33.0 million of the ALLL was allocated to unguaranteed loans.

The following tables present an analysis of the allowance of the loan and lease losses for the periods presented (dollars in thousands):

Non-Performing Assets

Non-performing loans and leases include loans and leases 90 days past due and still accruing and loans and leases accounted for on a non-accrual basis. Non-performing assets consist of non-performing loans and leases plus other real estate owned. Non-performing assets at March 31, 2022 and December 31, 2021 totaled $22.5 million and $25.2 million. The U.S. government guaranteed portion of non-performing loans totaled $1.8 million at March 31, 2022 and $3.3 million at December 31, 2021.

Total OREO increased from $2.1 million at December 31, 2021 to $2.2 million at March 31, 2022. The $109,000 increase in OREO resulted mostly from transfers to OREO.

The following table sets forth the amounts of non-performing loans and leases, non-performing assets, and OREO at the dates indicated (dollars in thousands):

(1) Includes $1.3 million and $1.5 million of non-accrual restructured loans at March 31, 2022 and December 31, 2021, respectively.

(2) For the three months ended March 31, 2022, $314,000 in interest income would have been recorded had non-accrual loans been current.

(3) For the three months ended March 31, 2022, $20,000 in interest income would have been recorded had troubled debt restructurings included within non-accrual loans been current.

Acquired impaired loans (accounted for under ASC 310-30) that are delinquent and/or on non-accrual status continue to accrue income provided the respective pool in which those assets reside maintains a discount and recognizes accretion income. The aforementioned loans are characterized as performing loans based on contractual delinquency. If the pool no longer has a discount and accretion income can no longer be recognized, any loan within that pool on non-accrual status will be classified as non-accrual for presentation purposes.

Total non-accrual loans decreased by $2.9 million between December 31, 2021 and March 31, 2022 primarily due to payoffs and continued economic improvement.

Total accruing loans past due decreased from $34.1 million at December 31, 2021 to $29.0 million at March 31, 2022. This represents a decrease of $5.1 million, or 14.9%, and can be attributed to decreases in residential real estate and construction, land development and other land, offset by increases to commercial real estate. See Note 5 of our Unaudited Interim Condensed Consolidated Financial Statements, included in this report, for further information.

Deposits

Our loan and lease growth is funded primarily through core deposits. We gather deposits primarily through each of our 37 branch locations in the Chicago metropolitan area and one branch in Brookfield, Wisconsin. Through our branch network, online, mobile and direct banking channels, we offer a variety of deposit products including demand deposit accounts, interest-bearing products, savings accounts, and certificates of deposit. We offer competitive online, mobile, and direct banking channels. Small businesses are a significant source of low cost deposits as they value convenience, flexibility, and access to local decision makers that are responsive to their needs.

Total deposits at March 31, 2022 were $5.5 billion, representing an increase of $375.1 million, or 7.3%, compared to $5.2 billion at December 31, 2021, driven by an increase in non-interest bearing deposits. Non-interest-bearing deposits were $2.3 billion, or 41.3% of total deposits, at March 31, 2022, an increase of $123.2 million, or 5.7%, compared to $2.2 billion at December 31, 2021, or 41.9% of total deposits. Core deposits were 93.1% and 91.9% of total deposits at March 31, 2022 and December 31, 2021, respectively.

The following table shows the average balance amounts and the average contractual rates paid on our deposits for the periods indicated (dollars in thousands):

All values are in US Dollars.

Our average cost of deposits was 0.08% during the three months ended March 31, 2022 compared to 0.12% during the three months ended March 31, 2021. These decreases were principally attributed to lower rates on interest-bearing deposits as a result the interest rate environment and an improved deposit mix. Our average non-interest bearing deposits to total average deposits ratios were 41.7% during the three months ended March 31, 2022 compared to 38.9% during the three months ended March 31, 2021. We had no brokered time deposits at March 31, 2022 and December 31, 2021, respectively. Our loan and lease to deposit ratio was 87.3% at March 31, 2022 compared to 89.3% at December 31, 2021.

The following table shows time deposits and other time deposits of $250,000 or more by time remaining until maturity as of March 31, 2022 (dollars in thousands):

All values are in US Dollars.

Total estimated uninsured deposits, were $1.8 billion and $1.6 billion as of March 31, 2022 and December 31, 2021, respectively.

Borrowed Funds

During 2020, the Company issued $75.0 million in fixed-to-floating subordinated notes that mature on July 1, 2030. The subordinated notes bear a fixed interest rate of 6.00% until July 1, 2025 and a floating interest rate equal to a benchmark rate, which is expected to be three-month Secured Overnight Financing Rate plus 588 basis points thereafter until maturity. The transaction resulted in debt issuance costs of approximately $1.7 million that are currently amortized over 10 years.

In addition to deposits, we also utilize FHLB advances as a supplementary funding source to finance our operations. The Bank’s advances from the FHLB are collateralized by residential and multi-family real estate loans and securities. At March 31, 2022 and December 31, 2021, we had an available borrowing capacity from the FHLB of $2.0 billion and $1.9 billion subject to the availability of collateral, respectively. At March 31, 2022, the Company had $280.0 million of FHLB advances with a maturities ranging from May 2022 to June 2022.

On April 21, 2020, the Bank entered into a Letter Agreement with the Federal Reserve Bank of Chicago that allows the Bank to access the Paycheck Protection Program Liquidity Facility (the “PPPLF”). Under the terms of the PPPLF, the Bank pledges loans originated under the PPP to the Federal Reserve Bank of Chicago as collateral for available advances under the PPPLF. Advances under the PPPLF are an amount equal to the aggregate principal amount of PPP loans pledged by Byline Bank, carry an interest rate of 35 basis points and mature on the maturity date of the PPP loans pledged as collateral for the advance. As of December 31, 2021, the amounts outstanding during 2021 under the PPPLF had been repaid and there was no amount outstanding under the facility.

The Company has the capacity to borrow funds from the discount window of the Federal Reserve System. There were no borrowings outstanding under the Federal Reserve Bank discount window line as of March 31, 2022 and December 31, 2021. The Company pledges loans as collateral for any borrowings under the Federal Reserve Bank discount window.

(1) We amended the credit agreement in October 2021, which extended the maturity date to October, 2022. The amended revolving line of credit bears interest at either the LIBOR Rate plus 195 basis points or the Prime Rate minus 75 basis points, based on our election, which is required to be communicate to the lender at least three business days prior to the commencement of an interest period. If we fail to provide timely notification, the interest rate will be Prime Rate minus 75 basis points.

Customer Repurchase Agreements (Sweeps)

Securities sold under agreements to repurchase represent a demand deposit product offered to customers that sweep balances in excess of the FDIC insurance limit into overnight repurchase agreements. We pledge securities as collateral for the repurchase agreements.

Securities sold under agreements to repurchase increased by $1.7 million, from $29.7 million at December 31, 2021 to $31.4 million at March 31, 2022.

Liquidity

We manage liquidity based upon factors that include the amount of core deposits as a percentage of total deposits, the level of diversification of our funding sources, the amount of non-deposit funding used to fund assets, the availability of unused funding sources, off-balance sheet obligations, the availability of assets to be readily converted into cash without undue loss, the amount of cash and liquid securities we hold and the re-pricing characteristics and maturities of our assets when compared to the re-pricing characteristics of our liabilities, the ability to securitize and sell certain pools of assets and other factors.

Our liquidity needs are primarily met by cash and investment securities positions, growth in deposits, cash flow from amortizing loan portfolios, and borrowings from the FHLB. For additional information regarding our operating, investing, and financing cash flows, see Consolidated Statements of Cash Flows in our Unaudited Interim Condensed Consolidated Financial Statements included elsewhere in this report.

As of March 31, 2022, Byline Bank had maximum borrowing capacity from the FHLB of $2.3 billion and $748.0 million from the Federal Reserve Bank (“FRB”). As of March 31, 2022, Byline Bank had open FHLB advances of $280.0 million and open letters of credit of $19.7 million, leaving us with available aggregate borrowing capacity of $354.4 million. In addition, Byline Bank had uncommitted federal funds lines available of $115.0 million at March 31, 2022.

As of December 31, 2021, Byline Bank had maximum borrowing capacity from the FHLB of $2.3 billion and $603.0 million from the FRB. As of December 31, 2021, Byline Bank had open advances of $490.0 million and open letters of credit of $19.7 million, leaving us with available aggregate borrowing capacity of $715.4 million based on collateral pledged. In addition, Byline Bank had an uncommitted federal funds line available of $115.0 million at December 31, 2021.

On October 13, 2016, we entered into a $30.0 million revolving credit agreement with a correspondent bank. Through subsequent amendments, the revolving credit agreement was reduced to $15.0 million and the maturity was extended to October 7, 2022. The amended revolving line of credit bears interest at either the LIBOR plus 195 basis points or the Prime Rate minus 75 basis points, based on our election, which is required to be communicated at least three business days prior to the commencement of an interest period. If we fail to provide timely notification, the interest rate will be Prime Rate minus 75 basis points. At March 31, 2022 and December 31, 2021, the line of credit had no outstanding balance.

There are regulatory limitations that affect the ability of Byline Bank to pay dividends to the Company. See Note 21 of our Consolidated Financial Statements, included in our Annual Report on Form 10-K for the year ended December 31, 2021 for additional information. Management believes that such limitations will not impact our ability to meet our ongoing short-term cash obligations.

We expect that our cash and liquidity resources will be generated by the operations of Byline Bank, which we expect to be sufficient to satisfy our liquidity and capital requirements for at least the next twelve months.

Capital Resources

Stockholders’ equity at March 31, 2022 was $788.7 million compared to $836.4 million at December 31, 2021, a decrease of $47.7 million, or 5.7%. The decrease was primarily driven by the increase in accumulated other comprehensive loss during the three months ended March 31, 2022, reflecting the unrealized losses in our available-for-sale securities portfolio, the redemption of preferred stock and the increase of treasury shares under the share repurchase program. Offset by an increase in retained earnings.

The Company and Byline Bank are subject to various regulatory capital requirements administered by federal banking regulators. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by federal banking regulators that, if undertaken, could have a direct material effect on our financial statements.

Under applicable bank regulatory capital requirements, each of the Company and Byline Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Byline Bank must also meet certain specific capital guidelines under the prompt corrective action framework. The capital amounts and classification are subject to qualitative judgments by the federal banking regulators about components, risk weightings and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Byline Bank to maintain minimum amounts and ratios of CET1 Capital, Tier 1 capital and total capital to risk-weighted assets and of Tier 1 capital to average consolidated assets, (referred to as the “leverage ratio”), as defined under these capital requirements.

As of March 31, 2022, Byline Bank exceeded all applicable regulatory capital requirements and was considered “well-capitalized.” There have been no conditions or events since March 31, 2022 that management believes have changed Byline Bank’s classifications.

The regulatory capital ratios for the Company and Byline Bank to meet the minimum capital adequacy standards and for Byline Bank to be considered well capitalized under the prompt corrective action framework and the Company’s and Byline Bank’s actual capital amounts and ratios are set forth in the following tables as of the periods indicated (dollars in thousands):

The Company and Byline Bank must maintain a capital conservation buffer consisting of CET1 capital greater than 2.5% of risk-weighted assets above the required minimum risk-based capital levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. The conservation buffers for the Company and Byline Bank exceed the minimum capital requirement as of March 31, 2022.

Provisions of state and federal banking regulations may limit, by statute, the amount of dividends that may be paid to the Company by Byline Bank without prior approval of Byline Bank’s regulatory agencies. The Company is economically dependent on the cash dividends received from Byline Bank. These dividends represent the primary cash flow from operating activities used to service obligations. For the three months ended March 31, 2022 the Company received $6.0 million in cash dividends from Byline Bank. For the year ended December 31, 2021, the Company received $24.0 million in cash dividends from Byline Bank in order to pay the required interest on its outstanding junior subordinated debentures in connection with its trust preferred securities interest, dividends on the Series B preferred stock outstanding, and to fund other Company-related activities.

On March 31, 2022, the Company redeemed all 10,438 outstanding shares of its 7.5% fixed-to-floating noncumulative perpetual preferred stock, Series B. The redemption totaled $10.6 million, including the quarterly dividend payment.

We purchased 282,819 shares at a cost of $7.6 million under our stock repurchase program during the three months ended March 31, 2022. We purchased 332,744 shares at a cost of $6.4 million under this program during the three months ended March 31, 2021. The program is in effect until December 31, 2022, unless terminated earlier.

On April 28, 2022, we announced that our Board of Directors declared a cash dividend on its common stock of $0.09 per share. The dividend will paid on May 23, 2022 to stockholders of record on May 9, 2022.

Off-Balance Sheet Items and Other Financing Arrangements

We are a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of our customers. These financial instruments include commitments to extend credit, commercial letters of credit and standby letters of credit. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the Consolidated Statements of Financial Condition. The contractual or notional amounts of those instruments reflect the extent of involvement we have in particular classes of financial instruments.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amount does not necessarily represent future cash requirements. We evaluate each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by Byline Bank upon extension of credit, is based on management’s credit evaluation of the counterparty. Collateral is primarily obtained in the form of commercial and residential real estate (including income producing commercial properties).

Letters of credit are conditional commitments issued by Byline Bank to guarantee the performance of a customer to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

Commitments to make loans are generally made for periods of 90 days or less. The fixed rate loan commitments have interest rates ranging from 1.25% to 18.00% and maturities up to 2045. Variable rate loan commitments have interest rates ranging from 1.25% to 15.00% and maturities up to 2048.

Our exposure to credit loss in the event of non-performance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual or notional amount of those instruments. We use the same credit policies in making commitments and conditional obligations as for funded instruments. We do not anticipate any material losses as a result of the commitments and standby letters of credit.

We enter into interest rate swaps that are used to manage differences in the amount, timing, and duration of our known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. We also enter into interest rate swaps with certain qualified borrowers to facilitate the borrowers’ risk management strategies and concurrently entered into mirror-image derivatives with a third party counterparty.

We recognize derivative financial instruments at fair value regardless of the purpose or intent for holding the instrument. We record derivative assets and derivative liabilities on the Consolidated Statements of Financial Condition within other assets and other liabilities, respectively. Because the derivative assets and liabilities recorded on the balance sheet at March 31, 2022 do not represent the amounts that may ultimately be paid under these contracts, these assets and liabilities are listed in the table below (dollars in thousands):

	March 31, 2022

GAAP Reconciliation and Management Explanation of Non-GAAP Financial Measures

Some of the financial measures included in our “Selected Financial Data” are not measures of financial performance in accordance with GAAP. Our management uses the non‑GAAP financial measures set forth below in its analysis of our performance:

• “Adjusted net income” and “adjusted diluted earnings per share” exclude certain significant items, which include impairment charges on assets held for sale, and right-of-use asset ("ROU") adjusted for applicable income tax. Management believes the significant items are not indicative of or useful to measure the Company’s operating performance on an ongoing basis.

• “Net interest income, fully taxable-equivalent” and “net interest margin, fully taxable-equivalent” are adjusted to reflect tax-exempt interest income on an equivalent before-tax basis using tax rates effective as of the end of the period. Management believes the metric provides useful comparable information to investors and that these measures may be useful for peer comparison.

• “Total revenue” is the combination of net interest income and non-interest income. Management believes the metric is an important measure of the Company's operating performance on an ongoing basis.

• “Adjusted non-interest expense” is non-interest expense excluding certain significant items, which include impairment charges on assets held for sale, merger-related expenses, and core system conversion expenses.

• “Adjusted efficiency ratio” is adjusted non-interest expense less amortization of intangible assets divided by net interest income and non-interest income. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Adjusted non-interest expense to average assets” is adjusted non-interest expense divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Adjusted return on average stockholders’ equity” is adjusted net income divided by average stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Adjusted return on average assets” is adjusted net income divided by average assets. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Non-interest income to total revenues” is non-interest income divided by net interest income plus non-interest income. Management believes that it is standard practice in the industry to present non-interest income as a percentage of total revenue. Accordingly, management believes providing these measures may be useful for peer comparison.

• “Pre‑tax pre‑provision net income” is pre‑tax income plus the provision for loan and lease losses. Management believes this metric demonstrates income excluding the tax provision or benefit and the provision for loan and lease losses, and enables investors and others to assess the Company’s ability to generate capital to cover credit losses through a credit cycle.

• “Adjusted pre-tax pre-provision net income” is pre-tax pre-provision net income excluding certain significant items, which include impairment charges on assets held for sale, and ROU asset. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Pre‑tax pre‑provision return on average assets” is pre-tax income plus the provision for loan and lease losses, divided by average assets. Management believes this ratio demonstrates profitability excluding the tax provision or benefit and excludes the provision for loan and lease losses. “Adjusted pre-tax pre-provision return on average assets” excludes certain significant items, which include impairment charges on assets held for sale, and ROU asset.

• “Tangible common equity” is defined as total stockholders’ equity reduced by preferred stock and goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

• “Tangible assets” is defined as total assets reduced by goodwill and other intangible assets. Management does not consider servicing assets as an intangible asset for purposes of this calculation.

• “Tangible book value per common share” is calculated as tangible common equity, which is stockholders’ equity reduced by preferred stock and goodwill and other intangible assets, divided by total shares of common stock outstanding. Management believes this metric is important due to the relative changes in the book value per share exclusive of changes in intangible assets.

• “Tangible common equity to tangible assets” is calculated as tangible common equity divided by tangible assets, which is total assets reduced by goodwill and other intangible assets. Management believes this metric is important to investors and analysts interested in relative changes in the ratio of total stockholders’ equity to total assets, each exclusive of changes in intangible assets.

• “Tangible net income available to common stockholders” is net income available to common stockholders excluding after-tax intangible asset amortization.

• “Adjusted tangible net income available to common stockholders” is tangible net income available to common stockholders excluding certain significant items. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Return on average tangible common stockholders’ equity” is tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

• “Adjusted return on average tangible common stockholders’ equity” is adjusted tangible net income available to common stockholders divided by average tangible common stockholders’ equity. Management believes the metric is an important measure of the Company’s operating performance on an ongoing basis.

We believe that these non‑GAAP financial measures provide useful information to its management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP; however, we acknowledge that our non‑GAAP financial measures have a number of limitations. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP financial measures that we and other companies use. Management also uses these measures for peer comparison.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

Our primary market risk is interest rate risk, which is defined as the risk of loss of net interest income or net interest margin because of changes in interest rates.

We seek to measure and manage the potential impact of interest rate risk. Interest rate risk occurs when interest-earning assets and interest-bearing liabilities mature or re-price at different times, on a different basis or in unequal amounts. Interest rate risk also arises when our assets, liabilities and off-balance sheet contracts each respond differently to changes in interest rates, including as a result of explicit and implicit provisions in agreements related to such assets and liabilities and in off-balance sheet contracts that alter the applicable interest rate and cash flow characteristics as interest rates change.

We are also exposed to interest rate risk through the retained portion of the U.S. government guaranteed loans we make and the related servicing rights. Our U.S. government guaranteed loan portfolio is comprised primarily of SBA 7(a) loans, virtually all of which are quarterly or monthly adjustable with the prime rate. The SBA portfolio reacts differently in a rising rate environment than our other non-guaranteed portfolios. Generally, when interest rates rise, the prepayments in the SBA portfolio tend to increase.

Our management of interest rate risk is overseen by our Board of Directors and management asset liability committees based on a risk management infrastructure approved by our Board of Directors that outlines reporting and measurement requirements. Our risk management infrastructure also requires a periodic review of all key assumptions used, such as identifying appropriate interest rate scenarios, setting loan prepayment rates based on historical analysis, non-interest-bearing and interest-bearing demand deposit lives based on historical analysis and the targeted investment term of capital. The committees closely monitor our interest sensitivity exposure, asset and liability allocation decisions, liquidity and capital positions, and local and national economic conditions and attempts to structure the loan and investment portfolios and funding sources to maximize earnings within acceptable risk tolerances.

We manage the interest rate risk associated with our interest-bearing liabilities by managing the interest rates and tenors associated with our borrowings from the FHLB, and deposits from our customers that we rely on for funding. We manage the interest rate risk associated with our interest-earning assets by managing the interest rates and tenors associated with our investment and loan portfolios, from time to time purchasing and selling investment securities.

We utilize interest rate derivatives to hedge our interest rate exposure on commercial loans when it meets our clients’ and Byline Bank’s needs. Typically, customer interest rate swaps are for terms of more than five years. As of March 31, 2022, we had a notional amount of $938.1 million of interest rate swaps outstanding, which includes customer swaps and those on Byline Bank’s balance sheet. The overall effectiveness of our hedging strategies is subject to market conditions, the quality of our execution, the accuracy of our valuation assumptions, the associated counterparty credit risk and changes in interest rates.

We use a net interest income simulation model to measure and evaluate potential changes in our net interest income. We run various hypothetical interest rate scenarios at least quarterly and compare these results against a scenario with no changes in interest rates. Our net interest income simulation model incorporates various assumptions, which we believe are reasonable but which may have a significant impact on results such as: (1) the timing of changes in interest rates, (2) shifts or rotations in the yield curve, (3) re-pricing characteristics for market-rate-sensitive instruments on and off balance sheet, (4) differing sensitivities of financial instruments due to differing underlying rate indices, (5) the effect of interest rate limitations in our assets, such as floors and caps, (6) the effect of our interest rate swaps and (7) overall growth and repayment rates and product mix of assets and liabilities. Because of limitations inherent in any approach used to measure interest rate risk, simulation results are not intended as a forecast of the actual effect of a change in market interest rates on our results but rather as a means to better plan and execute appropriate asset-liability management strategies and manage our interest rate risk.

Potential changes to our net interest income in hypothetical rising and declining rate scenarios calculated as of March 31, 2022 is presented below. In the current interest rate environment, a downward shift of the yield curve of 200, and 300 basis points does not provide meaningful results. In a downward parallel shift of the yield curve, interest rates at the short-end of the yield curve are not modeled to decline any further than 0%. For the dynamic balance sheet and rate shift scenarios, we assume interest rates follow a forward yield curve and then increase it by 1/12th of the total change in rates each month for 12 months.

	Immediate Shifts
Twelve Months Ending	+300 basis points			+200 basis points			+100 basis points			-100 basis points
Year 1
Percentage change		25.5	%		17.4	%		8.5	%		-5.2	%
Dollar amount	$	295,088		$	276,113		$	255,064		$	222,897
Year 2
Percentage change		34.8	%		23.6	%		11.7	%		-9.0	%
Dollar amount	$	337,941		$	309,896		$	279,919		$	228,023

For dynamic balance sheet and rate shifts, a gradual shift downward of 100 basis points would result in a 0.8% decrease in net interest income, and a gradual shift upwards of 100 and 200 basis points would result in 1.6% and 3.1% increases to net interest income, respectively, over the next 12 months.

The Bank's aggregate interest rate risk exposure is monitored and managed within board-approved policy limits. The results of this simulation analysis are hypothetical, and a variety of factors might cause actual results to differ substantially from what is depicted including the timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies.

Item 4. Controls and Procedures.

The Company’s management, including our Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our “disclosure controls and procedures” (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)), as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that, as of March 31, 2022, the Company’s disclosure controls and procedures were effective to provide reasonable assurance that the information required to be disclosed by the Company in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC and is accumulated and communicated to the Company’s management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting during the quarter ended March 31, 2022, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

Item 1. Legal Proceedings.

We operate in a highly regulated environment. From time to time we are a party to various litigation matters incidental to the conduct of our business. We are not presently party to any legal proceedings the resolution of which we believe would have a material adverse effect on our business, prospects, financial condition, liquidity, results of operation, cash flows or capital levels.

Item 1A. Risk Factors.

There have been no material changes to the risk factors previously disclosed in the “Risk Factors” section included in our Form 10-K for our fiscal year ended December 31, 2021 that was filed with the SEC on March 7, 2022.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

On December 10, 2020, we announced that our Board of Directors approved a stock repurchase program authorizing the purchase of up to an aggregate of 1,250,000 shares of our outstanding common stock. On July 27, 2021, our Board of Directors authorized an expansion of its current stock repurchase program. Under the extended program, we are authorized to repurchase an additional 1,250,000 shares of the Company's outstanding common stock. The shares may, at the discretion of management, be repurchased from time to time in open market purchases as market conditions warrant or in privately negotiated transactions. We are not obligated to purchase any shares under the program, and the program may be discontinued at any time. The actual timing, number and share price of shares purchased under the repurchase program will be determined by the Company at its discretion and will depend on a number of factors, including the market price of the Company’s stock, general market and economic conditions and applicable legal requirements. The program will be in effect until December 31, 2022 unless terminated earlier. The table below includes information regarding purchases of our common stock pursuant to the repurchase program during the quarter ended March 31, 2022.
