These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict.

Note 1: Nature of Operations and Summary of Significant Accounting Policies

Organization and Nature of Operations

CrossFirst Bankshares, Inc. (the ‘‘Company’’), a Kansas corporation, was incorporated in December 2017. Prior to incorporation, the Company was registered as a limited liability company under the name CrossFirst Holdings, LLC. The Company is a bank holding company whose principal activities are the ownership and management of its wholly-owned subsidiaries, CrossFirst Bank (the ‘‘Bank’’) and CFSA, LLC (“CFSA”), which holds title to certain assets. In addition, CrossFirst Investments, Inc. (‘‘CFI’’) is a wholly-owned subsidiary of the Bank, which holds investments in marketable securities.

Basis of Presentation

The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States (‘‘GAAP’’). The consolidated financial statements include the accounts of the Company; the Bank, CFI and CFSA. All significant intercompany accounts and transactions have been eliminated in consolidation.

The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted and should be read in conjunction with the Company’s consolidated financial statements, and notes thereto, for the six-months ended June 30, 2019 and year ended December 31, 2018 included in the Company’s prospectus, dated August 14, 2019, filed with the Securities and Exchange Commission (‘‘SEC’’) pursuant to Rule 424(b) of the Securities Act of 1933, as amended, on August 15, 2019, related to the Company’s initial public offering (the ‘‘IPO Prospectus’’).

In the opinion of management, the interim financial statements include all adjustments all of which are of a normal, recurring nature necessary for the fair presentation of the financial position, results of operations, and cash flows of the Company and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC.

There have been no significant changes in the accounting policies of the Company since June 30, 2019, the most recent date financial statements were provided within the IPO Prospectus.  The information contained in the financial statements and footnotes for the period ended June 30, 2019 included in the Company’s IPO Prospectus should be referred to in connection with these unaudited interim consolidated financial statements.

Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Use of Estimates

The Company has identified accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of the Company’s financial statements to those judgments and assumptions, are critical to an understanding of the Company’s financial condition and results of operations. Actual results could differ from those estimates. The Allowance for Loan and Lease Losses, Investment Securities Impairment, Deferred Tax Asset, and Fair Value of Financial Instruments are particularly susceptible to significant change.

Change in Presentation Due to Stock Split

On December 18, 2018, the Company announced a 2-for-1 stock split, effected in the form of a dividend, effective December 21, 2018. Share data and per share data were retroactively adjusted for the periods presented to reflect the change in capital structure.

Cash Equivalents

The Company had $85.0 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of September 30, 2019. The reserve required at September 30, 2019 was approximately $63.3 million. In addition, the

12

Table of Contents Notes to Unaudited Consolidated Financial Statements

Company is at times required to place cash collateral with a third party as part of its back-to-back swap agreements. At September 30, 2019, approximately $18.2 million was required as cash collateral.

Initial Public Offering

On August 19, 2019, the Company completed its initial public offering of common shares. The Company issued and sold 5,750,000 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $75.6 million from the initial public offering. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,261,589 common shares at a public offering price of $14.50 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders.

On September 17, 2019, the underwriters partially exercised their option to purchase additional shares. The Company issued and sold 844,362 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $11.4 million.

As of September 30, 2019, the Company qualified as an emerging growth company (‘‘EGC’’) under the Jumpstart Our Business Startups Act of 2012 (the ‘‘JOBS Act’’). An EGC may take advantage of reduced reporting requirements and is relieved of certain other significant requirements that are otherwise generally applicable to public companies. Amongst the reductions and reliefs, the Company elected to extend the transition period for complying with new or revised accounting standards affecting public companies. This means that the financial statements the Company files or furnishes, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an EGC or until the Company affirmatively and irrevocably opt out of the extended transition period under the JOBS Act.

Recent Accounting Pronouncements

The Company has implemented the following Accounting Standards Updates (‘‘ASU’’) during 2019:

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include (1) grants are measured at grant-date fair value of the equity instruments, (2) equity-classified nonemployee share-based payment awards are measured at the grant date, (3) performance based awards are measured based on the probability of satisfying the performance conditions, and (4) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to (i) set the fair market value of the non-employee awards as of the adoption date and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one-time transfer of $2.2 million from retained earnings to additional paid in capital. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.

Table of Contents Notes to Unaudited Consolidated Financial Statements

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $68.7 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry-specific guidance, established a new control-based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s non-interest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the IPO Prospectus:

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-13 Financial Instruments-Credit Losses	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2023 if it maintains its EGC status.	Requires an entity to utilize a new impairment model known as the current expected credit loss (’’CECL’’) model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and expects to complete a second parallel run using third quarter data during the fourth quarter. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The fourth quarter parallel run may provide a better estimate of the impact to the Company’s financial statements, but the actual impact could be significantly affected by the composition, characteristics and quality of the underlying loan portfolio at the time of adoption.

Table of Contents Notes to Unaudited Consolidated Financial Statements

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2021 if it maintains its EGC status.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company is electing to apply the update as of the beginning of the period of adoption and the Company will not restate comparative periods. The Company also expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company lease portfolio as of the adoption date.

The unrealized losses on the Company’s investments in state and political subdivisions were caused by interest rate changes and adjustments in credit ratings. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The unrealized losses on the Company’s investments in collateralized mortgage-backed securities and corporate bonds were caused by interest rate changes and market assumptions about prepayment speeds.

The Company expects to recover the amortized cost basis over the term of the securities, excluding a previously disclosed impaired security. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired (‘‘OTTI’’) at September 30, 2019.

Gross gains of $506.2 thousand and $2.0 million and gross losses of $39.4 thousand and $1.4 million resulting from sales of available-for-sale securities were realized for the nine-months ended September 30, 2019 and 2018, respectively.

Equity Securities

Equity securities consist of Community Reinvestment Act mutual funds. The fair value of the equity securities was $2.2 million and $2.1 million at September 30, 2019 and December 31, 2018, respectively. Prior to January 1, 2019, equity securities were stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. A net unrealized loss of $68.7 thousand had been recognized in accumulated other comprehensive income as of December 31, 2018. On January 1, 2019, the unrealized loss was reclassified out of accumulated other comprehensive income and into retained earnings with subsequent changes in fair value being recognized in other non-interest income. The following is a summary of the recorded fair value and the unrealized and realized gains and losses recognized in net income on available-for-sale equity securities:

Note 4: Loans and Allowance for Loan Losses

Categories of loans at September 30, 2019 and December 31, 2018 include:

	September 30, 2019		December 31, 2018
	(Dollars in thousands)
Commercial	$	1,312,647	$	1,134,414

Residential real estate	365,435		246,275
Equity lines of credit	22,192		20,286
Consumer installment	21,552		23,528
Gross loans	3,638,693		3,069,379
Less: Allowance for loan losses	42,995		37,826
Less: Net deferred loan fees and costs	8,901		8,632
Net loans	$	3,586,797	$	3,022,921

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers unclassified loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process and loan categories. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data.

The following tables summarize the activity in the allowance for loan losses by portfolio segment and disaggregated based on the Company’s impairment methodology. The allocation in one portfolio segment does not preclude its availability to absorb losses in other segments:

Credit Risk Profile

The Company analyzes its loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity. These categories are utilized to develop the associated allowance for loan losses. A description of the loan grades and segments follows:

Loan Grades

• Pass & Watch (risk rating 1 - 4) - Considered satisfactory. Includes borrowers that generally maintain good liquidity and financial condition or the credit is currently protected with sales trends remaining flat or declining. Most ratios compare favorably with industry norms and Company policies. Debt is programmed and timely repayment is expected.

• Special Mention (risk rating 5) - Borrowers generally exhibit adverse trends in operations or an imbalanced position in their balance sheet that has not reached a point where repayment is jeopardized. Credits are currently protected but, if left uncorrected, the potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s credit or lien position at a future date. These credits are not adversely classified and do not expose the Company to enough risk to warrant adverse classification.

• Substandard (risk rating 6) - Credits generally exhibit a well-defined weakness(es) that jeopardize repayment. Credits are inadequately protected by the current worth and paying capacity of the obligor or of the collateral pledged. A distinct possibility exists that the Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.

• Doubtful (risk rating 7) - Credits which exhibit weaknesses inherent in a substandard credit with the added characteristic that these weaknesses make collection or liquidation in full highly questionable and improbable based on existing facts, conditions and values. Because of reasonably specific pending factors, which may work to the advantage and strengthening of the assets, classification as a loss is deferred until its more exact status may be determined.

• Loss (risk rating 8) - Credits which are considered uncollectible or of such little value that their continuance as a bankable asset is not warranted.

Loan Portfolio Segments

• Commercial - Includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. Repayment is primarily from the cash flow of a borrower’s principal business operation. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

• Energy - Includes loans to oil and natural gas customers for use in financing working capital needs, exploration and production activities, and acquisitions. The loans in this category are repaid primarily from the conversion of crude oil and natural gas to cash. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

• Commercial Real Estate - Loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the company’s market areas.

• Construction and Land Development - Loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the company’s market areas.

• Residential Real Estate - The loans are generally secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans can be impacted by economic conditions within or outside the company’s market areas that might impact either property values or a borrower’s personal income. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over many borrowers.

• Equity Lines of Credit - The loans are revolving lines of credit extended to consumers secured through a first or second mortgage on their personal residence. Repayment is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans may be impacted by economic conditions within the company’s market areas that may impact either property values or a borrower’s personal income.

• Consumer Installment - The loan portfolio consists of various term and line of credit loans such as automobile loans and loans for other personal purposes. Repayment comes from a borrower’s income sources that are typically independent of the loan purpose. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s market area) and the creditworthiness of a borrower.

The following tables present the credit risk profile of the Company’s loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity:

Impaired Loans

A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.

Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

Non-accrual Loans

Nonperforming loans are loans for which the Company does not record interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table presents the Company’s non-accrual loans at September 30, 2019 and December 31, 2018:

Troubled Debt Restructurings

Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate.

As of September 30, 2019 and December 31, 2018, the Company had $896 thousand and $0, respectively, in commitments to borrowers whose terms have been modified in troubled debt restructurings. As of September 30, 2019, the modifications related to the troubled debt restructurings above did not impact the allowance for loan losses because the loans were previously impaired and evaluated on an individual basis or enough collateral was obtained to provide an additional commitment. The restructured loans had a total specific valuation allowance of $8.8 million and $2.4 million as of September 30, 2019 and December 31, 2018, respectively.

The balance of restructured loans is provided below as of September 30, 2019 and December 31, 2018. In addition, the balance of those loans that are in default at any time during the past twelve months at September 30, 2019 and December 31, 2018 is provided below:

Note 5: Derivatives and Hedging

Derivatives not designated as hedges are not speculative and result from a service the Company provides to clients. The Company executes interest rate swaps with customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives

associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

During the quarter ended September 30, 2019, the Company changed an input associated with the fair market value related to derivatives not designated as hedges. The model utilized to calculate the non-performance risk, also known as the credit valuation adjustment, or CVA, was adjusted from a more conservative default methodology to a review of the historical defaults recognized by the Company. Management believes this change better aligns with the Company’s credit methodology and underwriting standards.

As a result of the change in methodology, the Company increased swap fee income, net by approximately $800 thousand, related to swaps closed on or before June 30, 2019. If no defaults occur for derivatives not designated as hedges, the change in methodology will lower future swap fee income, net by the same amount.

As of September 30, 2019 and December 31, 2018, the Company had the following outstanding derivatives that were not designated as hedges in qualifying hedging relationships:

Note 8: Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Management believes that, as of September 30, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject.

The Company’s and the Bank’s actual capital amounts and ratios as of September 30, 2019 and December 31, 2018 are presented in the following table:

Note 9: Revenue from Contracts with Customers

The Company adopted ASU 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606)’’ and its related amendments as of January 1, 2019 using the modified retrospective approach. The implementation had no material impact on the measurement or recognition of revenue of either current or prior periods.

The categories are selected based on the nature, amount, timing, and uncertainty of revenue and cash flows. The following presents descriptions of revenue categories within the scope of ASU 2014-09 (ASC 606):

Service charges and fees (rebates) on customer accounts - This segment consists of monthly fees for the services rendered on customer deposit accounts, including maintenance charges, overdraft fees, and processing fees. The monthly fee structures are typically based on type of account, volume, and activity. The customer is typically billed monthly and pays the bill from their deposit account. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded.

ATM and credit card interchange income - This segment consists of fees charged for use of the Company’s ATMs, as well as, an interchange fee with credit card and debit card service providers. ATM fees and interchange fees are based on the number of transactions, as well as, the underlying agreements. Customers are typically billed monthly. The Company satisfies the performance obligation related to ATM and interchange fees monthly as transactions are processed and revenue is recorded.

International fees - This segment consists of fees earned from foreign exchange transactions and preparation of international documentation. International fees are based on underlying agreements that describe the Company’s performance obligation and the related fee. Customers are typically billed and cash is received once the service or transaction is complete. The Company satisfies the performance obligation related to international fees monthly as transactions are processed and revenue is recorded.

Other fees - This segment consists of numerous, smaller fees such as wire transfer fees, check cashing fees, and check printing fees. Other fees are typically billed to customers on a monthly basis. Performance obligations for other fees are satisfied at the time that the service is rendered.

The following table disaggregates the non-interest income subject to ASU 2014-09 by category:

	Three Months Ended					Nine Months Ended
	September 30,					September 30,
	2019		2018			2019		2018

Note 12: Disclosures about Fair Value of Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value:

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

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 Unobservable inputs supported by little or no market activity and significant to the fair value of the assets or liabilities.

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the Company’s accompanying consolidated balance sheets.

Available-for-Sale Securities

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy.

Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets.

Collateral-dependent Impaired Loans, Net of ALLL

The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. The impaired loans had a carrying value of $52.0 million and $59.7 million and were reduced by specific valuation allowance allocations totaling $11.8 million and $9.4 million at September 30, 2019 and December 31, 2018, respectively.

Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Office of the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Office of the Chief Credit Officer. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Office of the Chief Credit Officer by comparison to historical results.

Premises and Equipment Held-for-Sale

The estimated fair value of premises and equipment held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

34

Table of Contents Notes to Unaudited Consolidated Financial Statements

Foreclosed Assets Held-for-Sale

The estimated fair value of foreclosed assets held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value categorized within level 2 or level 3 above and not yet disclosed:

Loans

The Company adopted ASU 2016-01 on January 1, 2019. In accordance with its requirements, the fair value of loans as of September 30, 2019 was measured using an exit price notion. Methodologies utilized for this financial statement period are as follows: (i) Income Approach: Fair value is determined based on a discounted cash flow analysis. The discounted cash flow analysis was based on the contractual maturity of the loan and market indications of rates, prepayment speeds, defaults and credit risk; and (ii) Asset Approach: Fair value is determined based on the estimated values of the underlying collateral or individual analysis of receipts. This provides a better indication of value than the contractual income streams as these loans are not performing or exhibit strong signs indicative of non-performance. Fair value has been established in accordance with ASC 820, Fair Value Measurements and Disclosures, and is intended to represent the price that would be received in an orderly transaction between market participants as of the measurement date. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, at least one significant assumption not observable in the market was utilized. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Inputs to these valuation techniques are subjective in nature, involve uncertainties and require significant judgment and therefore cannot be determined with precision. Accordingly, the fair value estimates presented are not necessarily indicative of the amounts to be realized in a current market exchange.

For December 31, 2018, fair value was estimated by discounting the future cash flows using the market rates at which similar notes would be made to borrowers with similar credit ratings and for the same remaining maturities. The market rates used were based on current rates the Company would impose for similar loans and reflect a market participant assumption about risks associated with nonperformance, illiquidity, and the structure and term of the loans along with local economic and market conditions.

Restricted Equity Securities

Fair value is estimated at book value due to restrictions that limit the sale or transfer of such securities.

Interest Receivable and Payable

The carrying amount approximates fair value. The carrying amount is determined using the interest rate, balance and last payment date.

Deposits

Fair value of term deposits is estimated by discounting the future cash flows using rates of similar deposits with similar maturities. The estimated fair value of demand, transaction, savings and money market deposits is the book value since rates are regularly adjusted to market rates and amounts are payable on demand at the reporting date.

Federal Home Loan Bank Advances

Fair value is estimated by discounting the future cash flows using rates of similar advances with similar maturities. These rates were obtained from current rates offered by FHLB.

Fed Funds Purchased and Repurchase Agreements

Fair value for fed funds purchased is book value. Fair value of repurchase agreements estimated by discounting the future cash flows using rates of similar maturities.

Other Borrowings

Fair value of the Company’s line of credit with another financial institution is estimated at book value due to its short-term nature. The estimated fair value for the Trust Preferred Securities is based on current borrowing rates currently available to the Company, considering the size and quality of the credit and liquidity of the debt as a security.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes and with the statistical information and financial data appearing in this report as well as in The Company’s prospectus (File No. 333-232704) filed with the Securities & Exchange Commission (‘‘SEC’’) pursuant to Rule 424(b) of the Securities Act of 1933, as amended, on August 15, 2019, related to The Company’s initial public offering (the ‘‘IPO Prospectus’’). Results of operations for the three- and nine-month periods ended September 30, 2019 are not necessarily indicative of results to be attained for any other period.

Unless we state otherwise or the context otherwise requires, references in the below section to ‘‘we,’’ ‘‘our,’’ ‘‘us,’’ ‘‘ourselves,’’ ‘‘our company,’’ and the ‘‘Company’’ refer to CrossFirst Bankshares, Inc., a Kansas corporation, its predecessors and its consolidated subsidiaries. References to ‘‘CrossFirst Bank’’ and the ‘‘Bank’’ refer to CrossFirst Bank, a Kansas chartered bank and our wholly-owned consolidated subsidiary.

On December 21, 2018, we effected a two-for-one split of our common stock in the form of a stock dividend, whereby each holder of our common stock received one additional share of common stock for each share owned as of the record date of December 19, 2018. The effect of the stock dividend on outstanding shares and per share figures has been retroactively applied to all periods presented in this Form 10-Q.

Recent Developments

We completed our initial public offering on August 19, 2019 in which we issued and sold 6,594,362 common shares including 844,362 shares pursuant to the underwriters’ partial exercise of their overallotment option. The common shares were sold at an initial public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $87.0 million. The shares began trading on the Nasdaq Global Select Market under the symbol ‘‘CFB.’’

During the third quarter ended September 30, 2019, we accomplished the following:

• Increased total assets $178.1 million or 4.0% during the quarter to $4.7 billion, driven by a $162.4 million or 4.7% increase in our loan portfolio.

• Increased quarterly net income $945.0 thousand or 10.0% on a linked quarter basis, resulting in a quarterly return on average assets of 0.89% and return on average equity of 7.58%.

• Achieved an efficiency ratio of 54.3% during the quarter.

• Increased diluted earnings per share (‘‘EPS’’) 40% to $0.21 for the quarter from the same period in 2018.

• Increased year-to-date 2019 diluted EPS to $0.61, an increase of 177% from the same period in 2018.

GAAP Reconciliation and Management Explanation of Non-GAAP Financial Measures

Non-GAAP financial measures are used by management to evaluate our performance. The non-GAAP financial measures that we discuss should not be considered in isolation or as a substitute for the most directly comparable financial measures calculated in accordance with GAAP. Moreover, the way we calculate these non-GAAP financial measures may differ from that of other companies reporting measures with similar names.

We calculate ‘‘non-GAAP core operating income’’ as net income adjusted to remove non-recurring or non-core income and expense items related to:

• Restructuring charges associated with the transition of our former CEO - In connection with the departure of our former CEO in the second quarter of 2018, we incurred restructuring charges related to the acceleration of certain stock-based compensation and employee costs, some of which were adjusted in the fourth quarter of 2018.

• Impairment charges associated with two buildings that were held-for-sale - We acquired a larger corporate headquarters to accommodate our business needs that eliminated the need for two smaller support buildings. The two smaller support buildings had been acquired recently and were extensively remodeled, which resulted in a difference between book and market value for those assets. We sold one of the buildings in 2018 and the other in the second quarter of 2019.

• State tax credits - As a result of the purchase and improvement of our new corporate headquarters we received state tax credits.

The most directly comparable GAAP financial measure for non-GAAP core operating income is net income.

We calculate ‘‘non-GAAP core operating return on average assets’’ as non-GAAP core operating income (as defined above) divided by average assets. The most directly comparable GAAP financial measure is return on average assets, which is calculated as net income divided by average assets.

40

We calculate ‘‘non-GAAP core operating return on average equity’’ as non-GAAP core operating income (defined above) less preferred dividends divided by average common equity. The most directly comparable GAAP financial measure is return on average equity, which is calculated as net income less preferred dividends divided by average common equity.

We calculate ‘‘non-GAAP core operating efficiency ratio’’ as non-interest expense adjusted to remove non-recurring non-interest expenses as defined under non-GAAP core operating income divided by the sum of net interest income and non-interest income adjusted to remove non-recurring non-interest income as defined under non-GAAP core operating income. The most directly comparable GAAP financial measure is the efficiency ratio.

Management believes that non-GAAP core operating income, non-GAAP core operating return on average assets, non-GAAP core operating return on average equity and non-GAAP core operating efficiency ratio remove events that are not recurring and not part of core business activities and are useful analytical tools for investors to compare periods excluding these non-recurring or non-core income and charges.

The following table reconciles, as of the dates set forth below, net income to non-GAAP core operating income, non-GAAP core operating return on average assets, non-GAAP core operating return on average equity and non-GAAP core operating efficiency ratio:

We calculate ‘‘tangible common stockholders’ equity’’ as total stockholders’ equity less goodwill and other intangible assets and preferred stock. The most directly comparable GAAP financial measure is total stockholders’ equity.

We calculate ‘‘tangible book value per share’’ as tangible common stockholders’ equity (as defined above) divided by the number of shares of our common stock outstanding at the end of the relevant period. The most directly comparable GAAP financial measure is book value per share.

Management believes that tangible stockholders’ equity and tangible book value per share are important to many investors in the marketplace who are interested in changes from period to period in our stockholders’ equity, exclusive of changes in intangible assets. The following table reconciles, as of the dates set forth below, total stockholders’ equity to tangible stockholders’ equity and presents tangible book value per share compared to book value per share:

We calculate ‘‘Non-GAAP tax equivalent efficiency ratio’’ as non-interest expense divided by the sum of net interest income on a tax equivalent basis and non-interest income. Management believes the tax equivalent efficiency ratio provides a better understanding of our efficiency ratio because it gives effect for our tax-exempt security strategy.

Net Interest Income

We present and discuss net interest income on a tax-equivalent basis below. A tax-equivalent basis makes all income taxable at the same rate. For example, $100 of tax-exempt income would be presented as $126.58, an amount that, if taxed at the statutory federal income tax rate of 21% would yield $100. We believe a tax-equivalent basis provides for improved comparability between the various earning assets. The following table presents, for the period indicated, average balance sheet information, interest income, interest expense and the corresponding average yield and rates paid:

Changes 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 period shown. Information is provided with respect to: (i) changes in volume (change in volume times old rate); (ii) changes in rates (change in rate times old volume); and (iii) changes in rate/volume (change in rate times the change in volume).

Three months ended September 30, 2019 over 2018

For the three months ended September 30, 2019, net interest income increased $6.7 million or 22.5% from the same period in the prior year. Net interest income improved as a result of a $1.0 billion or 30.0% increase in average interest-earning assets offset by a 20 basis point decline in our net interest margin (‘‘NIM’’).

For the three months ended September 30, 2019, NIM was 3.24% compared to 3.44% in 2018. The declining margin was attributable to a rising interest rate environment in the third quarter of 2018 compared to two rate cuts by the Federal Open Market Committee (‘‘FOMC’’) in the third quarter of 2019. As a result, we experienced higher cost of funds as interest-bearing deposits repriced slower than our loan portfolio. The margin on gross loans, net of unearned income increased 18 basis points from 5.35% to 5.53% while the Company’s cost of funds increased 48 basis points from 1.46% to 1.94%. Changes in the yield and rate of interest-earning assets and interest-bearing liabilities decreased net interest income by $3.4 million.

Average volume for the three months ended September 30, 2019 compared to 2018 improved net interest income by $10.0 million. Average interest-earning assets were driven by a $1.0 billion or 40.3% increase in average loans. The growth in loans was primarily supported by a $847.2 million or 36.7% increase in interest-bearing deposits and a $43.5 million or 8.8% increase in non-interest-bearing deposits.

46

Nine months ended September 30, 2019 over 2018

For the nine-months ended September 30, 2019, net interest income increased $25.6 million or 31.8% from the same period in the prior year. Net interest income was driven by a $1.0 billion or 31.4% increase in average interest-earning assets. NIM increased 1 basis point as a result of four rate increases by the FOMC from March 2018 to December 2018, offset by two rate declines by the FOMC in July and September of 2019.

For the nine-months ended September 30, 2019, NIM was 3.35% compared to 3.34% in 2018. The yield on loans, net of unearned income increased 39 basis points to 5.64%, increasing interest income by $7.1 million offset by an increase in the cost of interest-bearing deposits of 71 basis points resulting in a $14.3 million increase in interest expense. While our margin improved, the overall impact of interest rates decreased net interest income by $7.8 million. Average volume for the nine-months ended September 30, 2019 compared to 2018 improved net interest income by $33.5 million. Average loans increased $1.1 billion or 48.3%, while average interest-bearing deposits increased $748.7 million or 33.4%. Net interest income reflects the Company’s strong balance sheet growth and maintenance of NIM.

As of September 30, 2019, approximately $223.8 million of time deposits mature in the fourth quarter at an average interest rate of 2.51%. An additional $331.2 million of time deposits mature during the first quarter of 2020 at an average interest of 2.67%.

Impact of Transition Away from LIBOR

The Company has loans, derivative contracts, and other financial instruments that directly or indirectly depend on LIBOR to establish an interest rate and/or value. This included $1.1 billion in loans tied to LIBOR as of September 30, 2019. LIBOR is expected to cease on December 31, 2021. The impact of alternatives to LIBOR on the valuations, pricing and operation of our financial instruments is not yet known; however, loans, securities, and derivatives indexed to LIBOR that mature after December 31, 2021 may be impacted. As a result, the Company established an internal committee to evaluate potential substitutions and the related financial impact to the Company.

Provision for Loan Losses

The provision for loan losses is a charge to earnings to maintain the allowance for loan losses at a level that reflects management’s assessment of the collectability of the loan portfolio. Net charge-offs (recoveries) represent a reduction (addition) to the allowance for loan losses for loans we believe are no longer collectible. The provision for loan losses was as follows for the periods shown:

	Three Months Ended								Nine Months Ended
	September 30,								September 30,
	2019		2018		$ Change		% Change		2019		2018		$ Change		% Change
	(Dollars in thousands)
Provision for loan losses	$	4,850	$	3,000	$	1,850	61.7	%	$	10,550	$	9,000	$	1,550	17.2	%

The allowance for loan losses as of September 30, 2019 was $43.0 million compared to $33.5 million as of September 30, 2018. The increase of $9.5 million or 28.2% was primarily due to an increase in our loan portfolio as well as an increase in non-performing loans, partially offset by a reduction in the energy portfolio’s qualitative factors. The allowance as a percentage of loans was 1.18% at September 30, 2019 compared to 1.22% at September 30, 2018.

The changes in non-interest income were driven by the following:

Swap Fee Income, Net

Swap fee income, net includes both swap fees from the execution of new swaps and the credit valuation adjustment (‘‘CVA’’). During the quarter, the Company added several large swaps, resulting in $1.1 million of swap fees compared to $272.7 thousand of fees from several, smaller swaps in the third quarter of 2018. Year-to-date 2019 swap fee activity totaled $2.4 million compared to $335.9 thousand in the prior year. The back-to-back swap program increased in activity during 2019 as a result of attractive market conditions.

In addition, the increase included a change in the CVA methodology during the third quarter of 2019. Prior to the third quarter, a more conservative default methodology was used to account for non-performance risk. The Company moved to a review of historical defaults and internal credit analysis performed by the Company. The result was an increase to non-interest income of approximately $800 thousand related to swaps entered in previous quarters.

ATM and Credit Card Interchange Income

Increased income was driven by the expansion of our credit card program to our new and existing customers.

Service Charges and Fees on Customer Accounts

This category includes a rebate program implemented in the second quarter of 2018 that attracted additional funding for the Bank and account analysis fees that continue to grow with our customer base.

Gain on Sale of Available for Sale Securities

The Company sold $63.5 million and $149.3 million of securities for the nine months ended 2019 and 2018, respectively. The sales were a strategic decision by management to capitalize on attractive market conditions, balance taxable and tax-free municipal securities, and redeploy the proceeds into higher yielding loans.

Impairment of Premises and Equipment Held for Sale

During the second quarter of 2019, the Company sold its remaining assets held-for-sale. The assets sold for approximately $2.9 million resulting in an additional impairment of $424.4 thousand.

The changes in non-interest income were driven by the following:

Salary and Employee Benefits

Quarterly salary and employee benefit costs increased as a result of a rise in headcount in 2019 and a $758.2 thousand increase in equity-based compensation expense. Year-to-Date salary and employee benefit costs decline was driven by a $5.5 million management restructuring charge due to the transition of our former CEO in 2018, partially offset by a net increase of 15 employees between September 30, 2018 and 2019 to support our growth strategy.

Deposit Insurance Premiums

During 2018, the Deposit Insurance Fund Reserve Ratio exceeded the statutorily required minimum reserve ratio. As a result, the Company received a $664.1 thousand assessment credit. The credit resulted in lower costs on both a quarter-to-date and year-to-date basis from the prior year. Credits will be applied until the excess is exhausted. Excluding the credit, the deposit insurance premium increased approximately $143.0 thousand during the third quarter of 2019 compared to the same period in 2018. The FDIC uses a risk-based premium system to calculate the quarterly fee. Between 2018 and 2019 our rate was impacted by our strong asset growth and changes to our loan mix.

Professional Fees

The professional fees decrease was driven by a reduction in recruitment costs from the prior year as a result of management’s strategic initiative to reduce the use of consultants. In addition, the Company saw a reduction in external consulting fees as we finalized our IPO plans.

Software and Communication

Software and communication costs increased during 2019 as a result of our continued strategy to invest in technologies that are expected to increase operating efficiency in the short and long-term.

Data Processing

Data processing includes our core system provided by a third-party and other operational support systems. Our customer base, transaction volume and asset size increased, resulting in higher data processing costs.

49

Advertising

Quarterly advertising costs increased from the previous year as the Company continued its rebranding process. Year-to-date advertising costs declined as a result of management’s strategic initiative to improve the efficiency and effectiveness of the Company’s targeted advertising.

Other non-interest expense

Other non-interest expense included an increase in commercial card costs that continue to increase as we grow our customer base. In addition, the Company had an increase in operational loan costs due to increased loan volume, types of loans originated or renewed and events related to foreclosed assets. Other non-interest expense also saw an increase in insurance costs due to our transition from a private to public company.

Income Taxes

Income tax expense (benefit) was as follows:

	Three Months Ended										Nine Months Ended
	September 30,										September 30,
	2019			2018			$ Change		% Change		2019			2018			$ Change		% Change
	(Dollars in thousands)
Income tax expense (benefit)	$	2,592		$	924		$	1,668	180.5	%	$	5,308		$	(904	)	$	6,212	NA
Effective tax rate	20.0		%	12.7		%					15.4		%	(10.8		)%

Our income tax expense (benefit) differs from the amount that would be calculated using the federal statutory tax rate, primarily from investments in tax advantaged assets, such as bank-owned life insurance and tax-exempt municipal securities, state tax credits, and permanent tax differences from equity-based compensation.

The $6.2 million increase between year-to-date September 30, 2018 and 2019 primarily relates to our $26.1 million increase in income before income taxes and a $334.0 thousand decline in permanent benefits associated with equity-based compensation that was partially offset by a $1.4 million state tax credit recorded in the first quarter of 2019. The state tax credit related to our purchase and improvement of our corporate headquarters.

Total stockholders’ equity	$	602,435	$	490,336	$	112,099		22.9	%

Assets grew primarily from loan growth, as well as, an increase in available-for-sale securities. Loan growth was driven by increases in commercial, commercial real estate, and residential real estate loans. During 2019, the Company

50

purchased $157.5 million of securities, primarily made up of mortgage backed securities and tax-exempt municipal securities, which was offset by $112.2 million of sales, maturities, and pay downs. Purchases of available-for-sale securities during the third quarter were hampered by the current interest rate environment. The Company remains committed to identifying and purchasing high-quality securities with an appropriate yield. Increases in assets were offset by a reduction in cash and cash equivalents, which was part of a strategic decision to move assets to higher yielding areas.

Our increase in assets was funded primarily from an increase in total deposits that raised the loan to deposit ratio to 99.2% as of September 30, 2019. The increase in total deposits included a $212.1 million increase in time deposits and a $144.1 million increase in money market and savings deposits. The time deposit increase was driven by short-term, competitive rates that are expected to mature over the next two quarters. In addition to our increase in deposits, the Company successfully completed an initial public offering during the third quarter of 2019 and was the primary reason for the increase in total stockholders’ equity.

Security Portfolio

The Company’s investment portfolio is governed by the investment policy that sets objectives, limits, and liquidity requirements among other items. The investment strategy is generally updated annually in coordination with an investment advisor. The portfolio is maintained to serve as a contingent, on-balance sheet source of liquidity. The objective of the Company’s investment portfolio is to optimize earnings, manage credit risk, ensure adequate liquidity, manage interest rate risk, meet pledging requirements, and meet regulatory capital requirements. The investment portfolio is generally comprised of government sponsored entity securities and U.S. state and political subdivision securities; limits are set on all types of securities.

As of September 30, 2019, available-for-sale investments totaled $733.1 million, a $69.4 million increase from December 31, 2018 and a $28.3 million or 4.0% increase from June 30, 2019. The increase in investment securities was part of management’s strategy to manage liquidity and optimize income. For additional information, see ‘‘Note 3 - Securities’’ in the notes to unaudited consolidated financial statements.

Net loans	$	3,586,797			$	3,022,921			$	563,876		18.7	%

As of September 30, 2019, gross loans increased $569.3 million or 18.5% from December 31, 2018 and increased $162.4 million or 4.7% on a linked quarter basis. The increase from December 31,2018 included $178.2 million in commercial loans. Our commercial portfolio remains well diversified with health care remaining our largest industry category at 12%.

51

Commercial real estate was the second largest segment for growth during the first nine-months of 2019. Approximately 73% of the commercial real estate portfolio is located within the states of Kansas, Missouri, Oklahoma, and Texas, with Texas, our largest state concentration, representing 40% of the portfolio as of September 30, 2019. The commercial real estate portfolio remains well diversified. Retail is the largest segment in our real estate loan portfolio, representing 15% of the portfolio.

Our energy portfolio increased from year-end 2018 but declined as a percentage of our total portfolio from 11.7% at December 31, 2018 to 10.9% at September 30, 2019. The Company continues to identify and attract strong energy credits, but currently expects to see less activity in the fourth quarter of 2019.

Residential real estate growth was driven by developing relationships within our markets.

Allowance for Loan Losses (‘‘ALLL’’)

The ALLL is an amount required to cover net loan charge-offs plus the amount considered necessary by the Bank’s management to maintain the balance in the allowance at a level adequate to absorb expected loan losses in the existing loan portfolio. The ALLL is evaluated on at least a quarterly basis. We use a loan grading system and portfolio segmentation to group the portfolio. Each group is evaluated and adjusted for changes in historical trends that may impact the segment. The ALLL at September 30, 2019, represents our best estimate of the incurred credit losses inherent in the loan portfolio at that date.

The allocation in one portfolio segment does not preclude its availability to absorb losses in other segments. The table below presents the allocation of the allowance for loan losses:

	September 30, 2019				December 31, 2018
	Amount		Percent of Allowance to Total Allowance		Amount	Percent of Allowance to Total Allowance

For the quarter ended September 30, 2019, the Company charged off $1.7 million related to a previously disclosed non-performing commercial loan. In addition, the Company charged off $3.0 million related to one oil exploration and production credit.

Our ALLL as of September 30, 2019 increased $9.5 million or 28.2% from September 30, 2018 and increased $142.5 thousand or less than 1% from June 30, 2019. Year-over-year, the ALLL has increased primarily from the growth of our loan portfolio and an increase in our impaired loans, offset by a reduction in the energy portfolio’s qualitative factors. On a linked quarter basis, our ALLL was impacted by $4.7 million in net charge-offs, a decline in our reserve required for our impaired loans, and a reduction in qualitative factors impacting our commercial and energy portfolios. As a result, the Company took a $4.9 million provision during the third quarter of 2019. Our ALLL to total loans declined 6 basis points to 1.18% as our loan portfolio continued to grow.

Nonperforming Assets and Other Asset Quality Metrics

Nonperforming assets include:

i. Nonperforming loans - includes non-accrual loans, loans past due 90 days or more and still accruing interest, and loans modified under troubled debt restructurings (‘‘TDRs’’) that are not performing in accordance with their modified terms;

ii. Foreclosed assets held for sale;

iii. Repossessed assets

iv. Impaired securities

The table below summarizes our nonperforming assets and related ratios as of the dates indicated:

September 30, 2019 nonperforming assets to total assets increased 65 basis points from the prior year driven by one commercial loan restructured in the second quarter of 2019 and subsequently placed on non-accrual. On a linked quarter basis, our September 30, 2019 nonperforming assets to total assets declined from 1.18% at June 30, 2019 to 1.00%.

Other asset quality metrics management reviews include loans past due 30 - 89 days and classified loans. The Company defines classified loans as loans categorized as substandard, doubtful or loss. The definitions of substandard, doubtful and loss see ‘‘Note 4 - Loans and Allowance for Loan Losses’’ in the notes to unaudited consolidated financial statements. The following table summarizes our loans past due 30 - 89 days, classified assets and related ratios:

	September 30, 2019			June 30, 2019			March 31, 2019			December 31, 2018			September 30, 2018

53

During the quarter ended, September 30, 2019 the Company experienced a $45.9 million increase in loans past due 30 to 59 days from $16.0 million to $61.9 million. The increase was driven by one commercial loan restructured during the second quarter of 2019 and subsequently placed on non-accrual, as well as, one construction and land development loan that was in the process of being renewed.

The Company's classified assets has trended down $16.3 million or 16.0% since December 31, 2018. The decline in classified assets is a combination of charge-offs, primarily from commercial and energy loans, and changes to loan risk ratings due to borrower improvements.

Deposits and Other Borrowings

Deposits and other borrowings are used to support our asset growth. Our strong asset growth requires us to place a greater emphasis on both interest and non-interest-bearing deposits. We attract and retain deposits by aggressively setting our deposit rates within our markets. Other borrowings supplement our core deposit strategy.

At September 30, 2019, our deposits totaled $3.7 billion, an increase of $450.0 million or 14.0% from December 31, 2018 and an increase of $74.0 million or 2.1% since June 30, 2019. Deposit growth was driven by competitive interest rates within our markets.

Other borrowings include repurchase agreements, fed funds purchased, FHLB borrowings, and our trust preferred security. At September 30, 2019, other borrowings totaled $358.5 million, a $30.7 million or 7.9% decline from December 31, 2018 and a $6.6 million decrease from June 30, 2019. The decline in other borrowings was driven by strong deposit growth and the successfully completed initial public offering.

Liquidity

The objective of the Company’s liquidity policy is to maintain adequate, but not excessive, liquidity to meet the daily cash flow needs of its clients while attempting to achieve adequate earnings for its stockholders. The liquidity position is monitored continuously by the Company’s finance department.

Liquidity resources can be derived from two sources: (i) on-balance sheet liquidity resources, which represent funds currently on the balance sheet and (ii) off-balance sheet liquidity resources, which represent funds available from third party sources. Our on-balance sheet and off-balance sheet liquidity resources consisted of the following:

Capital Resources and Off-Balance Sheet Arrangements

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Management believes that, as of September 30, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject. For additional information, see ‘‘Note 8 - Regulatory Matters’’ in the notes to unaudited consolidated financial statements.

The Company is subject to off-balance sheet risk in the normal course of business to meet the needs of its clients that have, or are reasonably likely to have, a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources. These off-balance sheet arrangements include commitments to fund loans, standby letters of credit, and a previously disclosed future lease obligation in Kansas City, Missouri.

Critical Accounting Policies

The Company identified several accounting policies that are critical to an understanding of our financial condition and results of operations. In addition, these policies require difficult, subjective or complex judgments and assumptions that create potential sensitivity of our financial statements to those judgments and assumptions. These policies relate to the allowance for loan and lease losses, investment securities impairment, deferred tax assets, and the fair value of financial instruments. A discussion of these policies can be found in the section captioned ‘‘Critical Accounting Policies’’ in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the IPO Prospectus. There have been no changes in the Company’s application of critical accounting policies since June 30, 2019.

Recent Accounting Pronouncements

The Company had the following updates to recent accounting pronouncements during the quarter. For additional information on accounting pronouncements, see Note 1 - Nature of Operations and Summary of Significant Accounting Policies. A complete list of recent, applicable accounting pronouncements was provided in the Company’s IPO Prospectus.

ASU 2016-13, Financial Instruments - Credit Losses - The Company established a committee of individuals from applicable departments to oversee the implementation process. The committee chose a third-party software solution. By the third quarter of 2019, the Company completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company completed a parallel run using 2019 data and expects to complete a second parallel run using third quarter data during the fourth quarter of 2019. At this time an estimate of the impact to the Company’s financial statements is not known, but the impact could be significantly affected by the composition, characteristics and quality of the underlying loan portfolio at the time of adoption.

ASU 2016-02, Leases (Topic 842) - The Company plans to apply the update as of the beginning of the period of adoption and is not planning to restate comparative periods. The Company expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. Current operating leases relate primarily to three branch locations. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on our balance sheet, with an immaterial impact on the income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company’s lease portfolio as of the adoption date.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

A primary component of market risk is interest rate volatility. Managing interest rate risk is a key element of the Company’s balance sheet management. Interest rate risk is the risk that net interest margin will erode over time due to changing market conditions. Many factors can cause margins to erode: (i) lower loan demand; (ii) increased competition for funds; (iii) weak pricing policies; (iv) balance sheet mismatches and (v) changing liquidity demands. The objective is to maximize income while minimizing interest rate risk. The Company manages its sensitivity position using its interest rate risk policy. The management of interest rate risk is a three-step process and involves: (i) measuring the interest rate risk position; (ii) policy constraints; and (iii) strategic review and implementation.

Our exposure to interest rate risk is managed by the Bank’s Funds Management Committee (‘‘FMC’’) in accordance with policies approved by the Bank’s board of directors. The FMC uses a combination of three systems to measure the

56

balance sheet’s interest rate risk position. Because each system serves a different purpose and provides a different perspective, the three systems in combination are expected to provide a better overall result than a single system alone. The three systems include: (i) gap reports; (ii) earnings simulation; and (iii) economic value of equity. The FMC’s primary tools to change the interest rate risk position are: (i) investment portfolio duration; (ii) deposit and borrowing mix; and (iii) on balance sheet derivatives.

The FMC evaluates interest rate risk using a rate shock method and rate ramp method. In a rate shock analysis, rates change immediately and the change is sustained over the time horizon. In a rate ramp analysis, rate changes occur gradually over time. The following tables summarize the simulated changes in net interest income and fair value of equity over a 12-month horizon using a rate shock and rate ramp method as of the dates indicated:

The hypothetical change in net interest income as of September 30, 2019 in a down or up 100 basis point shock is mainly due to approximately 67% of earning assets repricing or maturing over the next 12 months. Loans remain the largest portion of our adjustable earning assets, as the mix of adjustable loans to total loans was 71.5%. The amount of adjustable loans causes the Company to see an increase in net interest income in a rising rate environment and a decline in net interest income in a declining rate environment.

The models the Company uses include assumptions regarding interest rates and balance changes.  These assumptions are inherently uncertain and, as a result, the model cannot precisely estimate net interest income or precisely predict the impact of higher or lower interest rates on net interest income. Actual results will differ from simulated results due to timing, magnitude and frequency of interest rate changes as well as changes in market conditions, customer behavior and management strategies, among other factors.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

The Company’s management, with the participation of the Company’s Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (‘‘Exchange Act’’)) as of September 30, 2019. Based on that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective as of September 30, 2019.

Changes in Internal Control over Financial Reporting

There was no change in the Company’s internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) that occurred during the third quarter of 2019 that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the normal course of business, we are named or threatened to be named as a defendant in various lawsuits. Management, following consultation with legal counsel, does not expect the ultimate disposition of any or a combination of these matters to have a material adverse effect on our business, financial condition, results of operations, cash flows or growth prospects. However, given the nature, scope and complexity of the extensive legal and regulatory landscape applicable to our business (including laws and regulations governing consumer protection, fair lending, fair labor, privacy, information security and anti-money laundering and anti-terrorism laws), we, like all banking organizations, are subject to heightened legal and regulatory compliance and litigation risk.

ITEM 1A. RISK FACTORS

There were no material changes from the risks disclosed in the Risk Factors section of the IPO Prospectus (File No. 333-232704), dated August 14, 2019, filed with the SEC pursuant to Rule 424(b) of the Securities Act of 1933, as amended, on August 15, 2019.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

Unregistered Sales of Equity Securities

During the quarter ended September 30, 2019 and prior to September 13, 2019 (the date of the filing of our registration statement on Form S-8), we issued and sold an aggregate of 5,883 shares of our common stock to current employees at a weighted average exercise price of $17.00 per share pursuant to our partner share purchase program for aggregate cash consideration of $100.0 thousand. The shares were issued pursuant to an exemption under Rule 701 promulgated under the Securities Act. Each of the recipients of securities in these transactions had adequate access, through employment, to information about us.

During the quarter ended September 30, 2019 and prior to September 13, 2019 (the date of the filing of our registration statement on Form S-8), we issued 31,575 stock settled appreciation rights (‘‘SSARs’’) under our 2018 Equity Incentive Plan at a weighted average exercise price of $14.41 per unit. The SSARs vest in seven equal annual installments commencing in August 2020 and expire in August 2029.

In addition, during the quarter ended September 30, 2019 and prior to the filing of our Form S-8, we issued and sold to our employees an aggregate of 1,317 shares of common stock upon the exercise of SSARs issued under our 2018 Equity Incentive Plan at a weighted-average exercise price of $8.25 and a $17.00 price of the underlying security. The Company

58

withheld an aggregate of 599 shares of common stock subject to such SSARs for payment of the exercise price and satisfaction of the aggregate tax withholding obligations in connection with the exercises of certain of those SSARs.

The SSARs and the common stock issuable upon the exercise of such SSARs were issued under the 2018 Equity Incentive Plan in reliance on the exemption provided by Rule 701 promulgated under the Securities Act. Each of the recipients of securities in these transactions had adequate access, through employment, to information about us.

Use of Proceeds from our Initial Public Offering of Common Stock

On August 19, 2019, we completed our IPO, in which we sold 6,594,362 shares of common stock, including 844,362 shares pursuant to the underwriters' overallotment option, at price to the public of $14.50 per share. We received aggregate net proceeds of $87.0 million, net of underwriting discounts and commissions of $6.2 million and offering expenses paid by us of approximately $2.4 million subject to certain cost reimbursements. The offering has terminated. We distributed $50 million of the proceeds to our wholly-owned subsidiary, CrossFirst Bank, to support its growth. The balance of the proceeds for the offering was held at the Company and used for general corporate purposes. We made no payments to our directors, officers or persons owning ten percent or more of our common stock or to their associates, or to our affiliates in connection with the issuance and sale of the securities registered. We did not receive any proceeds from the sale of shares by the selling stockholders.

All the shares issued and sold in the initial public offering were registered under the Securities Act pursuant to a Registration Statement on Form S-1 (File No. 333-232704), which was declared effective by the SEC on August 14, 2019. Pursuant to the Registration Statement, we registered an aggregate of 7,855,951 shares of our common stock, inclusive of the underwriters’ option to purchase additional shares and the shares to be offered by selling stockholders. Keefe, Bruyette & Woods, A Stifel Company, Raymond James & Associates, Inc. and Stephens Inc. acted as joint book-running managers for the offering, and Sandler O’Neill + Partners, L.P. acted as co-manager of the offering.

There has been no material change in the planned use of the proceeds of the initial public offering as described in our IPO Prospectus (File No. 333-232704) filed with the SEC on August 15, 2019, pursuant to Rule 424(b) of the Securities Act. The Company intends to use the net proceeds from the offering to support our growth, organically or through mergers and acquisitions, and for general corporate purposes. As previously disclosed, the Company is currently considering using a portion of the net proceeds for the opening of a second smaller full-service branch in the Dallas MSA, in addition to consistently evaluating other strategic opportunities.

ITEM 3. DEFAULTS UPON SENIOR SECURITIES

Accounting Policies [Abstract]

Schedule of New Accounting Pronouncements and Changes in Accounting Principles

The Company has implemented the following Accounting Standards Updates (‘‘ASU’’) during 2019:

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include (1) grants are measured at grant-date fair value of the equity instruments, (2) equity-classified nonemployee share-based payment awards are measured at the grant date, (3) performance based awards are measured based on the probability of satisfying the performance conditions, and (4) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to (i) set the fair market value of the non-employee awards as of the adoption date and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one-time transfer of $2.2 million from retained earnings to additional paid in capital. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $68.7 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry-specific guidance, established a new control-based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s non-interest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the IPO Prospectus:

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-13 Financial Instruments-Credit Losses	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2023 if it maintains its EGC status.	Requires an entity to utilize a new impairment model known as the current expected credit loss (’’CECL’’) model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and expects to complete a second parallel run using third quarter data during the fourth quarter. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The fourth quarter parallel run may provide a better estimate of the impact to the Company’s financial statements, but the actual impact could be significantly affected by the composition, characteristics and quality of the underlying loan portfolio at the time of adoption.

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2021 if it maintains its EGC status.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company is electing to apply the update as of the beginning of the period of adoption and the Company will not restate comparative periods. The Company also expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company lease portfolio as of the adoption date.

Disclosures about Fair Value of Financial Instruments

Disclosures about Fair Value of Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value:

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

Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3 Unobservable inputs supported by little or no market activity and significant to the fair value of the assets or liabilities.

Recurring Measurements

The following tables present the fair value measurements of assets and liabilities recognized in the accompanying consolidated Balance Sheets measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall at September 30, 2019 and December 31, 2018:

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value on a recurring basis and recognized in the Company’s accompanying consolidated balance sheets.

Available-for-Sale Securities

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy.

Derivatives

Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts.

Nonrecurring Measurements

The following tables present assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at September 30, 2019 and December 31, 2018:

Following is a description of the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying consolidated balance sheets.

Collateral-dependent Impaired Loans, Net of ALLL

The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. The impaired loans had a carrying value of $52.0 million and $59.7 million and were reduced by specific valuation allowance allocations totaling $11.8 million and $9.4 million at September 30, 2019 and December 31, 2018, respectively.

Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Office of the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Office of the Chief Credit Officer. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Office of the Chief Credit Officer by comparison to historical results.

Premises and Equipment Held-for-Sale

The estimated fair value of premises and equipment held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

Foreclosed Assets Held-for-Sale

The estimated fair value of foreclosed assets held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

Following is a description of the valuation methodologies and inputs used for assets and liabilities measured at fair value categorized within level 2 or level 3 above and not yet disclosed:

Loans

The Company adopted ASU 2016-01 on January 1, 2019. In accordance with its requirements, the fair value of loans as of September 30, 2019 was measured using an exit price notion. Methodologies utilized for this financial statement period are as follows: (i) Income Approach: Fair value is determined based on a discounted cash flow analysis. The discounted cash flow analysis was based on the contractual maturity of the loan and market indications of rates, prepayment speeds, defaults and credit risk; and (ii) Asset Approach: Fair value is determined based on the estimated values of the underlying collateral or individual analysis of receipts. This provides a better indication of value than the contractual income streams as these loans are not performing or exhibit strong signs indicative of non-performance. Fair value has been established in accordance with ASC 820, Fair Value Measurements and Disclosures, and is intended to represent the price that would be received in an orderly transaction between market participants as of the measurement date. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, at least one significant assumption not observable in the market was utilized. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Inputs to these valuation techniques are subjective in nature, involve uncertainties and require significant judgment and therefore cannot be determined with precision. Accordingly, the fair value estimates presented are not necessarily indicative of the amounts to be realized in a current market exchange.

For December 31, 2018, fair value was estimated by discounting the future cash flows using the market rates at which similar notes would be made to borrowers with similar credit ratings and for the same remaining maturities. The market rates used were based on current rates the Company would impose for similar loans and reflect a market participant assumption about risks associated with nonperformance, illiquidity, and the structure and term of the loans along with local economic and market conditions.

Restricted Equity Securities

Fair value is estimated at book value due to restrictions that limit the sale or transfer of such securities.

Interest Receivable and Payable

The carrying amount approximates fair value. The carrying amount is determined using the interest rate, balance and last payment date.

Deposits

Fair value of term deposits is estimated by discounting the future cash flows using rates of similar deposits with similar maturities. The estimated fair value of demand, transaction, savings and money market deposits is the book value since rates are regularly adjusted to market rates and amounts are payable on demand at the reporting date.

Federal Home Loan Bank Advances

Fair value is estimated by discounting the future cash flows using rates of similar advances with similar maturities. These rates were obtained from current rates offered by FHLB.

Fed Funds Purchased and Repurchase Agreements

Fair value for fed funds purchased is book value. Fair value of repurchase agreements estimated by discounting the future cash flows using rates of similar maturities.

Other Borrowings

Fair value of the Company’s line of credit with another financial institution is estimated at book value due to its short-term nature. The estimated fair value for the Trust Preferred Securities is based on current borrowing rates currently available to the Company, considering the size and quality of the credit and liquidity of the debt as a security.

Regulatory Matters

Regulatory Matters

The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Management believes that, as of September 30, 2019, the Company and the Bank meet all capital adequacy requirements to which they are subject.

The Company’s and the Bank’s actual capital amounts and ratios as of September 30, 2019 and December 31, 2018 are presented in the following table:

Loans and Allowance for Loan Losses

Categories of loans at September 30, 2019 and December 31, 2018 include:

	(Dollars in thousands)

Less: Net deferred loan fees and costs	8,901		8,632
Net loans	$	3,586,797	$	3,022,921

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers unclassified loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process and loan categories. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data.

The following tables summarize the activity in the allowance for loan losses by portfolio segment and disaggregated based on the Company’s impairment methodology. The allocation in one portfolio segment does not preclude its availability to absorb losses in other segments:

Credit Risk Profile

The Company analyzes its loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity. These categories are utilized to develop the associated allowance for loan losses. A description of the loan grades and segments follows:

Loan Grades

• Pass & Watch (risk rating 1 - 4) - Considered satisfactory. Includes borrowers that generally maintain good liquidity and financial condition or the credit is currently protected with sales trends remaining flat or declining. Most ratios compare favorably with industry norms and Company policies. Debt is programmed and timely repayment is expected.

• Special Mention (risk rating 5) - Borrowers generally exhibit adverse trends in operations or an imbalanced position in their balance sheet that has not reached a point where repayment is jeopardized. Credits are currently protected but, if left uncorrected, the potential weaknesses may result in deterioration of the repayment prospects for the credit or in the Company’s credit or lien position at a future date. These credits are not adversely classified and do not expose the Company to enough risk to warrant adverse classification.

• Substandard (risk rating 6) - Credits generally exhibit a well-defined weakness(es) that jeopardize repayment. Credits are inadequately protected by the current worth and paying capacity of the obligor or of the collateral pledged. A distinct possibility exists that the Company will sustain some loss if deficiencies are not corrected. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard.

• Doubtful (risk rating 7) - Credits which exhibit weaknesses inherent in a substandard credit with the added characteristic that these weaknesses make collection or liquidation in full highly questionable and improbable based on existing facts, conditions and values. Because of reasonably specific pending factors, which may work to the advantage and strengthening of the assets, classification as a loss is deferred until its more exact status may be determined.

• Loss (risk rating 8) - Credits which are considered uncollectible or of such little value that their continuance as a bankable asset is not warranted.

Loan Portfolio Segments

• Commercial - Includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions. Repayment is primarily from the cash flow of a borrower’s principal business operation. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

• Energy - Includes loans to oil and natural gas customers for use in financing working capital needs, exploration and production activities, and acquisitions. The loans in this category are repaid primarily from the conversion of crude oil and natural gas to cash. Credit risk is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations.

• Commercial Real Estate - Loans typically involve larger principal amounts, and repayment of these loans is generally dependent on the successful operations of the property securing the loan or the business conducted on the property securing the loan. These are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the company’s market areas.

• Construction and Land Development - Loans are usually based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are higher risk than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the company’s market areas.

• Residential Real Estate - The loans are generally secured by owner-occupied 1-4 family residences. Repayment of these loans is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans can be impacted by economic conditions within or outside the company’s market areas that might impact either property values or a borrower’s personal income. Risk is mitigated by the fact that the loans are of smaller individual amounts and spread over many borrowers.

• Equity Lines of Credit - The loans are revolving lines of credit extended to consumers secured through a first or second mortgage on their personal residence. Repayment is primarily dependent on the personal income and credit rating of the borrowers. Credit risk in these loans may be impacted by economic conditions within the company’s market areas that may impact either property values or a borrower’s personal income.

• Consumer Installment - The loan portfolio consists of various term and line of credit loans such as automobile loans and loans for other personal purposes. Repayment comes from a borrower’s income sources that are typically independent of the loan purpose. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the Company’s market area) and the creditworthiness of a borrower.

The following tables present the credit risk profile of the Company’s loan portfolio based on an internal rating category (grades 1 - 8), portfolio segment and payment activity:

Impaired Loans

A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.

Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

The following tables present impaired loans for the periods ended September 30, 2019 and December 31, 2018:

Non-accrual Loans

Nonperforming loans are loans for which the Company does not record interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The following table presents the Company’s non-accrual loans at September 30, 2019 and December 31, 2018:

	September 30, 2019		December 31, 2018

Troubled Debt Restructurings

Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate.

The table below presents loans restructured during the three- and nine-months ended September 30, 2019 and 2018, including the post-modification outstanding balance and the type of concession made:

As of September 30, 2019 and December 31, 2018, the Company had $896 thousand and $0, respectively, in commitments to borrowers whose terms have been modified in troubled debt restructurings. As of September 30, 2019, the modifications related to the troubled debt restructurings above did not impact the allowance for loan losses because the loans were previously impaired and evaluated on an individual basis or enough collateral was obtained to provide an additional commitment. The restructured loans had a total specific valuation allowance of $8.8 million and $2.4 million as of September 30, 2019 and December 31, 2018, respectively.

The balance of restructured loans is provided below as of September 30, 2019 and December 31, 2018. In addition, the balance of those loans that are in default at any time during the past twelve months at September 30, 2019 and December 31, 2018 is provided below:

The unrealized losses on the Company’s investments in state and political subdivisions were caused by interest rate changes and adjustments in credit ratings. The contractual terms of those investments do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investments. The unrealized losses on the Company’s investments in collateralized mortgage-backed securities and corporate bonds were caused by interest rate changes and market assumptions about prepayment speeds.

The Company expects to recover the amortized cost basis over the term of the securities, excluding a previously disclosed impaired security. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of their amortized cost basis, which may be maturity, the Company does not consider those investments to be other-than-temporarily impaired (‘‘OTTI’’) at September 30, 2019.

Gross gains of $506.2 thousand and $2.0 million and gross losses of $39.4 thousand and $1.4 million resulting from sales of available-for-sale securities were realized for the nine-months ended September 30, 2019 and 2018, respectively.

Equity Securities

Equity securities consist of Community Reinvestment Act mutual funds. The fair value of the equity securities was $2.2 million and $2.1 million at September 30, 2019 and December 31, 2018, respectively. Prior to January 1, 2019, equity securities were stated at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income, net of tax. A net unrealized loss of $68.7 thousand had been recognized in accumulated other comprehensive income as of December 31, 2018. On January 1, 2019, the unrealized loss was reclassified out of accumulated other comprehensive income and into retained earnings with subsequent changes in fair value being recognized in other non-interest income. The following is a summary of the recorded fair value and the unrealized and realized gains and losses recognized in net income on available-for-sale equity securities:

Nature of Operations and Summary of Significant Accounting Policies (Policies)

9 Months Ended

Sep. 30, 2019

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States (‘‘GAAP’’). The consolidated financial statements include the accounts of the Company; the Bank, CFI and CFSA. All significant intercompany accounts and transactions have been eliminated in consolidation.

The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted and should be read in conjunction with the Company’s consolidated financial statements, and notes thereto, for the six-months ended June 30, 2019 and year ended December 31, 2018 included in the Company’s prospectus, dated August 14, 2019, filed with the Securities and Exchange Commission (‘‘SEC’’) pursuant to Rule 424(b) of the Securities Act of 1933, as amended, on August 15, 2019, related to the Company’s initial public offering (the ‘‘IPO Prospectus’’).

In the opinion of management, the interim financial statements include all adjustments all of which are of a normal, recurring nature necessary for the fair presentation of the financial position, results of operations, and cash flows of the Company and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC.

There have been no significant changes in the accounting policies of the Company since June 30, 2019, the most recent date financial statements were provided within the IPO Prospectus.  The information contained in the financial statements and footnotes for the period ended June 30, 2019 included in the Company’s IPO Prospectus should be referred to in connection with these unaudited interim consolidated financial statements.

Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Use of Estimates

Use of Estimates

The Company has identified accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of the Company’s financial statements to those judgments and assumptions, are critical to an understanding of the Company’s financial condition and results of operations. Actual results could differ from those estimates. The Allowance for Loan and Lease Losses, Investment Securities Impairment, Deferred Tax Asset, and Fair Value of Financial Instruments are particularly susceptible to significant change.

Cash Equivalents

Cash Equivalents

The Company had $85.0 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of September 30, 2019. The reserve required at September 30, 2019 was approximately $63.3 million. In addition, the

Company is at times required to place cash collateral with a third party as part of its back-to-back swap agreements. At September 30, 2019, approximately $18.2 million was required as cash collateral.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The Company has implemented the following Accounting Standards Updates (‘‘ASU’’) during 2019:

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include (1) grants are measured at grant-date fair value of the equity instruments, (2) equity-classified nonemployee share-based payment awards are measured at the grant date, (3) performance based awards are measured based on the probability of satisfying the performance conditions, and (4) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to (i) set the fair market value of the non-employee awards as of the adoption date and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one-time transfer of $2.2 million from retained earnings to additional paid in capital. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $68.7 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry-specific guidance, established a new control-based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s non-interest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the IPO Prospectus:

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-13 Financial Instruments-Credit Losses	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2023 if it maintains its EGC status.	Requires an entity to utilize a new impairment model known as the current expected credit loss (’’CECL’’) model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and expects to complete a second parallel run using third quarter data during the fourth quarter. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The fourth quarter parallel run may provide a better estimate of the impact to the Company’s financial statements, but the actual impact could be significantly affected by the composition, characteristics and quality of the underlying loan portfolio at the time of adoption.

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2021 if it maintains its EGC status.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company is electing to apply the update as of the beginning of the period of adoption and the Company will not restate comparative periods. The Company also expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company lease portfolio as of the adoption date.

Allowance for Loan Losses

The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the loan balance is not collectible. Subsequent recoveries, if any, are credited to the allowance.

The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of its ability to collect the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.

The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers unclassified loans and is based on historical charge-off experience and expected loss given default derived from the Company’s internal risk rating process and loan categories. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data.

Impaired Loans

A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable the Company will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. The intent of concessions is to maximize collection.

Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans.

Non-accrual Loans

Non-accrual Loans

Nonperforming loans are loans for which the Company does not record interest income. The accrual of interest on mortgage and commercial loans is discontinued at the time the loan is 90 days past due unless the credit is well secured and in process of collection. Past due status is based on contractual terms of the loan. In all cases, loans are placed on non-accrual or charged off at an earlier date, if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on non-accrual or charged off are reversed against interest income. The interest on these loans is accounted for on the cash basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled Debt Restructurings

Restructured loans are those extended to borrowers who are experiencing financial difficulty and who have been granted a concession. The modification of terms typically includes the extension of maturity, reduction or deferment of monthly payment, or reduction of the stated interest rate.

Fair Value Measurement

Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Office of the Chief Credit Officer. Appraisals are reviewed for accuracy and consistency by the Office of the Chief Credit Officer. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the Office of the Chief Credit Officer by comparison to historical results.

Available-for-Sale Securities

Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy.

Derivatives

Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts.

Collateral-dependent Impaired Loans, Net of ALLL

The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value.

Premises and Equipment Held-for-Sale

The estimated fair value of premises and equipment held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

Foreclosed Assets Held-for-Sale

The estimated fair value of foreclosed assets held-for-sale is based on the appraised fair value of the collateral, less estimated cost to sell.

The Company adopted ASU 2016-01 on January 1, 2019. In accordance with its requirements, the fair value of loans as of September 30, 2019 was measured using an exit price notion. Methodologies utilized for this financial statement period are as follows: (i) Income Approach: Fair value is determined based on a discounted cash flow analysis. The discounted cash flow analysis was based on the contractual maturity of the loan and market indications of rates, prepayment speeds, defaults and credit risk; and (ii) Asset Approach: Fair value is determined based on the estimated values of the underlying collateral or individual analysis of receipts. This provides a better indication of value than the contractual income streams as these loans are not performing or exhibit strong signs indicative of non-performance. Fair value has been established in accordance with ASC 820, Fair Value Measurements and Disclosures, and is intended to represent the price that would be received in an orderly transaction between market participants as of the measurement date. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, at least one significant assumption not observable in the market was utilized. These unobservable assumptions reflect estimates that market participants would use in pricing the asset or liability. Inputs to these valuation techniques are subjective in nature, involve uncertainties and require significant judgment and therefore cannot be determined with precision. Accordingly, the fair value estimates presented are not necessarily indicative of the amounts to be realized in a current market exchange.

For December 31, 2018, fair value was estimated by discounting the future cash flows using the market rates at which similar notes would be made to borrowers with similar credit ratings and for the same remaining maturities. The market rates used were based on current rates the Company would impose for similar loans and reflect a market participant assumption about risks associated with nonperformance, illiquidity, and the structure and term of the loans along with local economic and market conditions.

Restricted Equity Securities

Fair value is estimated at book value due to restrictions that limit the sale or transfer of such securities.

Interest Receivable and Payable

The carrying amount approximates fair value. The carrying amount is determined using the interest rate, balance and last payment date.

Deposits

Fair value of term deposits is estimated by discounting the future cash flows using rates of similar deposits with similar maturities. The estimated fair value of demand, transaction, savings and money market deposits is the book value since rates are regularly adjusted to market rates and amounts are payable on demand at the reporting date.

Federal Home Loan Bank Advances

Fair value is estimated by discounting the future cash flows using rates of similar advances with similar maturities. These rates were obtained from current rates offered by FHLB.

Fed Funds Purchased and Repurchase Agreements

Fair value for fed funds purchased is book value. Fair value of repurchase agreements estimated by discounting the future cash flows using rates of similar maturities.

Other Borrowings

Fair value of the Company’s line of credit with another financial institution is estimated at book value due to its short-term nature. The estimated fair value for the Trust Preferred Securities is based on current borrowing rates currently available to the Company, considering the size and quality of the credit and liquidity of the debt as a security.

Revenue from Contracts with Customers

Revenue from Contracts with Customers

The Company adopted ASU 2014-09, ‘‘Revenue from Contracts with Customers (Topic 606)’’ and its related amendments as of January 1, 2019 using the modified retrospective approach. The implementation had no material impact on the measurement or recognition of revenue of either current or prior periods.

The categories are selected based on the nature, amount, timing, and uncertainty of revenue and cash flows. The following presents descriptions of revenue categories within the scope of ASU 2014-09 (ASC 606):

Service charges and fees (rebates) on customer accounts - This segment consists of monthly fees for the services rendered on customer deposit accounts, including maintenance charges, overdraft fees, and processing fees. The monthly fee structures are typically based on type of account, volume, and activity. The customer is typically billed monthly and pays the bill from their deposit account. The Company satisfies the performance obligation related to providing depository accounts monthly as transactions are processed and deposit service charge revenue is recorded.

ATM and credit card interchange income - This segment consists of fees charged for use of the Company’s ATMs, as well as, an interchange fee with credit card and debit card service providers. ATM fees and interchange fees are based on the number of transactions, as well as, the underlying agreements. Customers are typically billed monthly. The Company satisfies the performance obligation related to ATM and interchange fees monthly as transactions are processed and revenue is recorded.

International fees - This segment consists of fees earned from foreign exchange transactions and preparation of international documentation. International fees are based on underlying agreements that describe the Company’s performance obligation and the related fee. Customers are typically billed and cash is received once the service or transaction is complete. The Company satisfies the performance obligation related to international fees monthly as transactions are processed and revenue is recorded.

Other fees - This segment consists of numerous, smaller fees such as wire transfer fees, check cashing fees, and check printing fees. Other fees are typically billed to customers on a monthly basis. Performance obligations for other fees are satisfied at the time that the service is rendered.

The following table disaggregates the non-interest income subject to ASU 2014-09 by category:

	Three Months Ended					Nine Months Ended
	September 30,					September 30,
	2019		2018			2019		2018

Derivatives and Hedging

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Hedging

Derivatives and Hedging

Derivatives not designated as hedges are not speculative and result from a service the Company provides to clients. The Company executes interest rate swaps with customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting derivatives that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate derivatives

associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer derivatives and the offsetting derivatives are recognized directly in earnings.

During the quarter ended September 30, 2019, the Company changed an input associated with the fair market value related to derivatives not designated as hedges. The model utilized to calculate the non-performance risk, also known as the credit valuation adjustment, or CVA, was adjusted from a more conservative default methodology to a review of the historical defaults recognized by the Company. Management believes this change better aligns with the Company’s credit methodology and underwriting standards.

As a result of the change in methodology, the Company increased swap fee income, net by approximately $800 thousand, related to swaps closed on or before June 30, 2019. If no defaults occur for derivatives not designated as hedges, the change in methodology will lower future swap fee income, net by the same amount.

As of September 30, 2019 and December 31, 2018, the Company had the following outstanding derivatives that were not designated as hedges in qualifying hedging relationships:

	September 30, 2019			December 31, 2018
Product	Number of Instruments	Notional Amount		Number of Instruments	Notional Amount
	(Dollars in thousands)
Back-to-back swaps	46	$	308,960	20	$	77,709

The table below presents the fair value of the Company’s derivative financial instruments and their classification on the Balance Sheet as of September 30, 2019 and December 31, 2018:

	Asset Derivatives					Liability Derivatives
	Balance Sheet	September 30,		December 31,		Balance Sheet	September 30,		December 31,
	Location	2019		2018		Location	2019		2018
	(Dollars in thousands)
Derivatives not designated as hedging instruments
Interest rate products	Other assets	$	13,735	$	1,051	Other liabilities	$	13,782	$	1,136

The effect of the Company’s derivative financial instruments that are not designated as hedging instruments are reported on the Statements of Income as swap fee income, net. The effect of the Company’s derivative financial instruments gain and loss are reported on the Statements of Cash Flows within other assets and other liabilities.

The tables below show a gross presentation, the effects of offsetting, and a net presentation of the Company’s derivatives as of September 30, 2019 and December 31, 2018:

The net presentation above can be reconciled to the tabular disclosure of fair value.

As of September 30, 2019, the Company had minimum collateral posting thresholds with certain of its derivative counter-parties and had posted collateral of $18.2 million. If the Company had breached any of these provisions at September 30, 2019, it could have been required to settle its obligations under the agreements at their termination value of $13.8 million.

The consolidated interim financial statements are unaudited and certain information and footnote disclosures presented in accordance with GAAP have been condensed or omitted and should be read in conjunction with the Company’s consolidated financial statements, and notes thereto, for the six-months ended June 30, 2019 and year ended December 31, 2018 included in the Company’s prospectus, dated August 14, 2019, filed with the Securities and Exchange Commission (‘‘SEC’’) pursuant to Rule 424(b) of the Securities Act of 1933, as amended, on August 15, 2019, related to the Company’s initial public offering (the ‘‘IPO Prospectus’’).

In the opinion of management, the interim financial statements include all adjustments all of which are of a normal, recurring nature necessary for the fair presentation of the financial position, results of operations, and cash flows of the Company and the disclosures made are adequate to make the interim financial information not misleading. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC.

There have been no significant changes in the accounting policies of the Company since June 30, 2019, the most recent date financial statements were provided within the IPO Prospectus.  The information contained in the financial statements and footnotes for the period ended June 30, 2019 included in the Company’s IPO Prospectus should be referred to in connection with these unaudited interim consolidated financial statements.

Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

Use of Estimates

The Company has identified accounting policies and estimates that, due to the difficult, subjective or complex judgments and assumptions inherent in those policies and estimates and the potential sensitivity of the Company’s financial statements to those judgments and assumptions, are critical to an understanding of the Company’s financial condition and results of operations. Actual results could differ from those estimates. The Allowance for Loan and Lease Losses, Investment Securities Impairment, Deferred Tax Asset, and Fair Value of Financial Instruments are particularly susceptible to significant change.

Change in Presentation Due to Stock Split

On December 18, 2018, the Company announced a 2-for-1 stock split, effected in the form of a dividend, effective December 21, 2018. Share data and per share data were retroactively adjusted for the periods presented to reflect the change in capital structure.

Cash Equivalents

The Company had $85.0 million of cash and cash equivalents at the Federal Reserve Bank of Kansas City as of September 30, 2019. The reserve required at September 30, 2019 was approximately $63.3 million. In addition, the

Company is at times required to place cash collateral with a third party as part of its back-to-back swap agreements. At September 30, 2019, approximately $18.2 million was required as cash collateral.

Initial Public Offering

On August 19, 2019, the Company completed its initial public offering of common shares. The Company issued and sold 5,750,000 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $75.6 million from the initial public offering. In addition, certain selling stockholders participated in the offering and sold an aggregate of 1,261,589 common shares at a public offering price of $14.50 per share. The Company did not receive any proceeds from the sales of shares by the selling stockholders.

On September 17, 2019, the underwriters partially exercised their option to purchase additional shares. The Company issued and sold 844,362 common shares at a public offering price of $14.50 per share. After deducting the underwriting discounts and offering expenses, the Company received total net proceeds of $11.4 million.

As of September 30, 2019, the Company qualified as an emerging growth company (‘‘EGC’’) under the Jumpstart Our Business Startups Act of 2012 (the ‘‘JOBS Act’’). An EGC may take advantage of reduced reporting requirements and is relieved of certain other significant requirements that are otherwise generally applicable to public companies. Amongst the reductions and reliefs, the Company elected to extend the transition period for complying with new or revised accounting standards affecting public companies. This means that the financial statements the Company files or furnishes, will not be subject to all new or revised accounting standards generally applicable to public companies for the transition period for so long as the Company remains an EGC or until the Company affirmatively and irrevocably opt out of the extended transition period under the JOBS Act.

Recent Accounting Pronouncements

The Company has implemented the following Accounting Standards Updates (‘‘ASU’’) during 2019:

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2018-07 - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting	January 2019 Early adoption	Expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees, excluding share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments include (1) grants are measured at grant-date fair value of the equity instruments, (2) equity-classified nonemployee share-based payment awards are measured at the grant date, (3) performance based awards are measured based on the probability of satisfying the performance conditions, and (4) in general, non-employee share-based payment awards will continue to be subject to the requirements of ASC 718 unless modified after the good has been delivered, the service has been rendered, any other conditions necessary to earn the right to benefit from the instrument have been satisfied, and the nonemployee is no longer providing goods or services.	The Company had 216,960 stock-based awards to non-employees as of the implementation date, including 116,960 performance-based restricted stock units. The adoption of the ASU allowed the Company to (i) set the fair market value of the non-employee awards as of the adoption date and (ii) start to expense the performance-based restricted stock units based on the probability of satisfying the performance conditions. Adoption of ASU 2018-07 required the Company to make a one-time transfer of $2.2 million from retained earnings to additional paid in capital. The Company will record forfeitures as they occur and base fair market values on the expected term, like the Company’s accounting for employee-based awards.

Standard	Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-01 - Financial Instruments-Overall (Subtopic 825-10)	January 2019	Required equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. Emphasized the existing requirement to use exit prices to measure fair value for disclosure purposes and clarifies that entities should not make use of practicability exceptions in determining the fair value of loans.	The Company transferred $68.7 thousand from accumulated other comprehensive loss to retained earnings in January 2019. There was no impact to the income statement on the adoption date.
ASU 2014-09 - Revenue from Contracts with Customers	January 2019	Amended guidance related to revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Replaced nearly all existing revenue recognition guidance, including industry-specific guidance, established a new control-based revenue recognition model, changed the basis for deciding when revenue is recognized over time or at a point in time, provided new and more detailed guidance on specific topics and expands and improves disclosures about revenue.	The accounting update did not materially impact the financial statements or recognition of revenues. The update did not apply to revenue associated with financial instruments, including loans and securities that are accounted for under other GAAP, which comprises a significant portion of the Company’s revenue stream. In addition, the Company’s non-interest income is generated by customer transactions or through the passage of time and as a result the pattern or timing of income recognition was not impacted.

The Company has updates to the following ASUs that have not yet been adopted. A complete list of recent, applicable accounting pronouncements was provided in the IPO Prospectus:

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-13 Financial Instruments-Credit Losses	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2023 if it maintains its EGC status.	Requires an entity to utilize a new impairment model known as the current expected credit loss (’’CECL’’) model to estimate its lifetime expected credit loss and record an allowance that, when deducted from amortized cost basis of the financial asset, presents the net amount expected to be collected on the financial asset.	The Company has established a committee of individuals from applicable departments to oversee the implementation process. The Company implemented a third-party software solution and completed the software implementation phase of the transition. The software implementation phase included data capture and portfolio segmentation amongst other items. The Company has completed an initial parallel run using 2019 data and expects to complete a second parallel run using third quarter data during the fourth quarter. At this time, an estimate of the impact cannot be established as the Company continues to evaluate the inputs into the model. The fourth quarter parallel run may provide a better estimate of the impact to the Company’s financial statements, but the actual impact could be significantly affected by the composition, characteristics and quality of the underlying loan portfolio at the time of adoption.

Standard	Anticipated Date of Adoption	Description	Effect on Financial Statements or Other Significant Matters
ASU 2016-02 Leases (Topic 842)	The Company expects to implement this standard in 2020; however, the Company is not required to implement this standard until January 2021 if it maintains its EGC status.	Requires lessees and lessors to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The update requires lessees and lessors to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach with the option to elect certain practical expedients. The update will also increase disclosures around leases, including qualitative and specific quantitative measures.	The Company is electing to apply the update as of the beginning of the period of adoption and the Company will not restate comparative periods. The Company also expects to elect certain optional practical expedients. The Company gathered all potential lease and embedded lease agreements and is evaluating the applicability and impact to the financial statements. The Company’s current operating leases relate primarily to three branch locations. Based on these current leases, the Company anticipates recognizing a lease liability and related right-to-use asset on its balance sheet, with an immaterial impact to its income statement compared to the current lease accounting model. However, the ultimate impact of the standard will depend on the Company lease portfolio as of the adoption date.
