Nature of Operations and Summary of Significant Accounting Policies
Nature of Operations and Summary of Significant Accounting Policies	Note 1: Nature of Operations and Summary of Significant Accounting Policies Organization and Nature of Operations CrossFirst Bankshares, Inc. (“Bankshares or “CrossFirst”) is a bank holding company whose principal activities are the ownership and management of its wholly-owned subsidiary, CrossFirst Bank (the “Bank”). In addition, the Bank has three subsidiaries, including CrossFirst Investments, Inc. (“CFI”), which holds investments in marketable securities, CFBSA I, LLC and CFBSA II, LLC. On August 26, 2024, Bankshares and First Busey Corporation, a Nevada corporation (“Busey”), entered into an Agreement and Plan of Merger (the “Merger Agreement”). The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Bankshares will merge with and into Busey, with Busey as the surviving corporation in the merger (the “Merger”). The Merger Agreement further provides that at a date and time following the Merger as determined by Busey, CrossFirst Bank, a Kansas state-chartered bank and a wholly owned subsidiary of CrossFirst, will merge with and into Busey Bank, an Illinois state-chartered bank and a wholly owned subsidiary of Busey, with Busey Bank as the surviving bank. The transaction is subject to customary closing conditions, including the approval of both Busey and CrossFirst stockholders and the regulatory approvals for the holding company merger and the bank merger. Subject to obtaining these approvals, the parties currently expect to close the holding company merger in the first or second quarter of 2025. Upon the terms and subject to the conditions set forth in the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of CrossFirst (“CrossFirst Common Stock”) outstanding immediately prior to the Effective Time, other than certain shares held by CrossFirst or Busey, will be converted into the right to receive 0.6675 of a share of common stock, par value $0.001 per share, of Busey. Holders of CrossFirst Common Stock will receive cash in lieu of fractional shares. At the Effective Time, each share of Series A Non-Cumulative Perpetual Preferred Stock, par value $0.01 per share, of CrossFirst (“CrossFirst Preferred Stock” or “Series A Preferred Stock”) outstanding immediately prior to the Effective Time will be converted into the right to receive one share of a newly created series of preferred stock of Busey, provided that at the election of Busey, Busey may cause the CrossFirst Preferred Stock to be converted in the Merger at the Effective Time into the right to receive an amount of cash equal to the liquidation preference thereof, plus the amount of any accrued and unpaid dividends thereon through the Effective Time. The Bank is engaged in providing a full range of banking and financial services to individual and corporate clients primarily through its branches in: (i) Leawood, Kansas; (ii) Wichita, Kansas; (iii) Kansas City, Missouri; (iv) Oklahoma City, Oklahoma; (v) Tulsa, Oklahoma; (vi) Dallas, Texas; (vii) Fort Worth, Texas; (viii) Frisco, Texas; (ix) Phoenix, Arizona; (x) Tucson, Arizona; (xi) Colorado Springs, Colorado; (xii) Denver, Colorado; and (xiii) Clayton, New Mexico. Basis of Presentation The accompanying interim unaudited consolidated financial statements serve to update the CrossFirst Bankshares, Inc. Annual Report on Form 10-K for the year ended December 31, 2023 and include the consolidated accounts of Bankshares, the Bank, CFI, CFBSA I, LLC and CFBSA II, LLC (together, referred to herein as the “Company”). The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies. However, they may not include all information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods and accordingly should be read in conjunction with the financial information contained in the Company's most recent Annual Report on Form 10-K. The unaudited consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results presented. All such adjustments are of a normal recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications of prior years' amounts are made whenever necessary to conform to current period presentation. The results of operations for the interim period are not necessarily indicative of the results that may be expected for the full year or any other interim period. All amounts are in thousands, except share data, or as otherwise noted. GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. By their nature, estimates are based on judgment and available information. Management has made significant estimates in certain areas, such as the fair values of financial instruments, and the allowance for credit losses (“ACL”). Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from those estimates. The Company's significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in Note 1 of the audited financial statements and notes for the year ended December 31, 2023 and are contained in the Company's Annual Report on Form 10-K for that period. There have been no significant changes to the application of significant accounting policies since December 31, 2023. Related Party Transactions The Bank extends credit and receives deposits from related parties. In management’s opinion, the loans and deposits were made in the ordinary course of business and made on similar terms as those prevailing at the time with other persons. Related party loans totaled $10 million and $12 million, while related party deposits totaled $90 million and $106 million, at September 30, 2024 and December 31, 2023, respectively.

The unrealized losses in the Company’s investment portfolio were primarily caused by interest rate changes. 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. The Company did not record any credit losses on AFS securities during the nine months ended September 30, 2024 or the year ended December 31, 2023.

Tax-exempt securities are not tax effected. ​ Equity Securities Equity securities consist of $7.3 million of private equity investments. Equity securities are included in other assets on the consolidated statements of financial condition. The Company elected a measurement alternative for its private equity investments that did not have a readily determinable fair value and did not qualify for the practical expedient to estimate fair value using the net asset value per share. A cost basis was calculated for the equity investments. The recorded balance will adjust for any impairment or any observable price changes for an identical or similar investment of the same issuer.

The Company aggregates the loan portfolio by similar credit risk characteristics. The loan segments are described in additional detail below: ● Commercial and Industrial - The category includes loans and lines of credit to commercial and industrial clients for use in property, plant, and equipment purchases, business operations, expansions and for working capital needs. Loan terms typically require amortizing payments that decrease the outstanding loan balance while the lines of credit typically require interest-only payments with maturities ranging from one- to three-years. Lines of credit allow the borrower to draw down and repay the line of credit based on the borrower’s cash flow needs. 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 - The category includes loans to oil and natural gas clients for use in financing working capital needs, exploration and production activities, and acquisitions. The loans 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. Energy loans are typically collateralized with the underlying oil and gas reserves. ● Commercial Real Estate - Owner-Occupied - The category includes relationships where the Company is usually the primary provider of financial services for the company and/or the principals and the primary source of repayment is through the cash flows generated by the borrowers’ business operations. Owner-occupied commercial real estate loans are typically secured by a first lien mortgage on real property plus assignments of all leases related to the properties. Credit risk may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas. ● Commercial Real Estate – Non-Owner-Occupied - The category includes loans that typically involve larger principal amounts and repayment of these loans is generally dependent on the leasing income generated from tenants. These are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Additionally, the category includes construction and land development loans that are based upon estimates of costs and estimated value of the completed project. Independent appraisals and a financial analysis of the developers and property owners are completed. Sources of repayment include secondary market 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. The category also includes loans that are secured by multifamily properties. Repayment of these loans is primarily dependent on occupancy rates and rental income. Credit risk for non-owner-occupied commercial real estate loans may be impacted by the creditworthiness of a borrower, property values and the local economies in the borrower’s market areas. ● Residential Real Estate - The category includes loans that 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. We also offer open- and closed-ended home equity loans, which are loans generally secured by second lien positions on residential real estate. Credit risk in these loans can be impacted by economic conditions within or outside the borrower’s market areas that might impact either property values or a borrower’s personal income. ● Consumer - The category includes personal lines of credit and various term loans such as automobile loans and loans for other personal purposes. Repayment is primarily dependent on the personal income and credit rating of the borrowers. Credit risk is driven by consumer economic factors (such as unemployment and general economic conditions in the borrower’s market area) and the creditworthiness of a borrower. Risk Ratings The Company uses a series of grades which reflect its assessment of the credit quality of loans based on an analysis of the borrower's financial condition, liquidity and ability to meet contractual debt service requirements. Risk ratings are established for loans at origination and are monitored on an ongoing basis. The rating assigned to a loan reflects the risks posed by the borrower’s expected performance and the transaction’s structure. Performance metrics used to determine a risk rating include, but are not limited to, cash flow adequacy, liquidity, and collateral. A description of the loan risk ratings follows: ● Pass - The category includes loans that are considered satisfactory and 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 - The category includes borrowers that 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 - The category includes borrowers that generally exhibit 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. Substandard loans include both performing and non-performing loans and are broken out in the table below. ● Doubtful - The category includes borrowers that exhibit weaknesses inherent in a substandard credit and characteristics that these weaknesses make collection or liquidation in full highly questionable or 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 - Credits that are considered uncollectible or of such little value that their continuance as a bankable asset is not warranted. ​ The following tables present the credit risk profile of the Company’s loan portfolio based on internal rating categories and loan segments: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2024 ​ ​ Amortized Cost Basis by Origination Year and Internal Risk Rating ​ Amortized Cost Basis ​ 2024 2023 2022 2021 2020 2019 and Prior Revolving Loans Revolving Loans Converted to Term Loans Total ​ ​ (Dollars in thousands) Commercial and industrial ​ ​ ​ ​ ​ ​ ​ ​ ​ Pass ​ $ 297,434 ​ $ 227,975 ​ $ 197,696 ​ $ 119,558 ​ $ 32,895 ​ $ 12,589 ​ $ 1,119,666 ​ $ 72,450 ​ $ 2,080,263 Special mention ​ 682 ​ 11,572 ​ 12,948 ​ 14,859 ​ — ​ 15 ​ 26,868 ​ 1,008 ​ 67,952 Substandard -

The accrual of interest on 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. 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 committee estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. The ACL represents the Company’s current estimate of lifetime credit losses inherent in the loan portfolio at the statement of financial condition date. The ACL is adjusted for expected prepayments when appropriate and excludes expected extensions, renewals, and modifications. The ACL is the sum of three components: (i) asset specific / individual loan reserves; (ii) quantitative (formulaic or pooled) reserves; and (iii) qualitative (judgmental) reserves. Asset Specific - Quantitative Qualitative ● The nature and volume of changes in risk ratings; ● The volume and severity of past due loans; ● The volume of non-accrual loans; ● The nature and volume of the loan portfolio, including the existence, growth, and effect of any concentrations of credit; ● Changes in the Institute of Supply Management’s Purchasing Manager Indices (“PMI”) for services and manufacturing; ● Changes in collateral values; ● Changes in lending policies, procedures, and quality of loan reviews; ● Changes in lending staff; and ● Changes in competition, legal and regulatory environments In addition to the current condition qualitative adjustments, the Company uses the Federal Reserve’s unemployment forecast to adjust the ACL based on forward-looking guidance. The Federal Reserve’s unemployment forecast extends three years and is eventually reverted to the mean of six percent by year 10. ​ The following table presents the activity in the allowance for credit losses and allowance for credit losses on off-balance sheet credit exposures by loan segment for the three and nine months ended September 30, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended September 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate ​ Real Estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ ​ ​ ​ Owner- ​ Non-owner- ​ Residential ​ ​ ​ ​ ​ ​ ​ and Industrial Energy Occupied Occupied Real Estate Consumer Total ​ ​ (Dollars in thousands) Allowance for Credit Losses: ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 33,627 ​ $ 3,325 ​ $ 6,691 ​ $ 29,082 ​ $ 3,423 ​ $ 70 ​ $ 76,218 Charge-offs ​ (1,599) ​ — ​ — ​ (23) ​ — ​ — ​ (1,622) Recoveries ​ 24 ​ — ​ — ​ 4 ​ — ​ — ​ 28 Provision (release) ​ 1,896 ​ (126) ​ (596) ​ 2,137 ​ (337) ​ 159 ​ 3,133 Ending balance ​ $ 33,948 ​ $ 3,199 ​ $ 6,095 ​ $ 31,200 ​ $ 3,086 ​ $ 229 ​ $ 77,757 Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: ​ ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 783 ​ $ 133 ​ $ 107 ​ $ 4,119 ​ $ 67 ​ $ 4 ​ $ 5,213 Provision (release) ​ 100 ​ — ​ — ​ 306 ​ (9) ​ 3 ​ 400 Ending balance ​ $ 883 ​ $ 133 ​ $ 107 ​ $ 4,425 ​ $ 58 ​ $ 7 ​ $ 5,613 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Nine Months Ended September 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate ​ Real Estate ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ ​ ​ ​ Owner- ​ Non-owner- ​ Residential ​ ​ ​ ​ ​ ​ ​ and Industrial Energy Occupied Occupied Real Estate Consumer Total ​ ​ (Dollars in thousands) Allowance for Credit Losses: ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ 32,244 ​ $ 3,143 ​ $ 6,445 ​ $ 28,1

Leases
Leases	Note 4: Leases The Company’s leases primarily include bank branches located in Kansas City, Missouri; Tulsa, Oklahoma; Dallas, Texas; Frisco, Texas; Fort Worth, Texas; Phoenix, Arizona; Denver, Colorado; and Colorado Springs, Colorado. The remaining lease terms on these branch leases range from less than one year to 18 years with certain options to renew. Renewal terms can extend the lease term between five years and 20 years. The exercise of lease renewal options is at the Company’s sole discretion. When it is reasonably certain that the Company will exercise its option to renew or extend the lease term, that option is included in the estimated value of the right of use (“ROU”) asset and lease liability. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants. As of September 30, 2024, the Company recognized one finance lease and the remaining Company leases were classified as operating leases. During the third quarter of 2024, the Company entered into a lease agreement for a new bank branch in Oklahoma City, Oklahoma. The lease is expected to commence during the fourth quarter of 2024. The lease will be recognized in the Company’s consolidated financial statements during the period that includes the lease’s commencement date. The ROU asset is included in “Other assets” on the consolidated statements of financial condition, and was $28 million and $30 million at September 30, 2024 and December 31, 2023, respectively. Certain adjustments to the ROU asset may be required for items such as initial direct costs paid or incentives received. The lease liability is located in “Interest payable and other liabilities” on the consolidated statements of financial condition and was $31 million and $34 million at September 30, 2024 and December 31, 2023, respectively. As of September 30, 2024, the remaining weighted-average lease term was 10.2 years, and the weighted-average discount rate was 2.78% utilizing the Company’s incremental Federal Home Loan Bank (“FHLB”) borrowing rate for borrowings of a similar term at the date of lease commencement.

Goodwill and Core Deposit Intangible
Goodwill and Core Deposit Intangible	Note 5: Goodwill and Core Deposit Intangible Goodwill is measured as the excess of the fair value of consideration paid over the fair value of net assets acquired. In accordance with GAAP, the Company performs annual tests to identify impairment of goodwill and more frequently if events or circumstances indicate a potential impairment may exist. No goodwill impairment was recorded during the nine months ended September 30, 2024. The Company is amortizing the core deposit intangible (“CDI”) over its estimated useful life of approximately 10 years from the date of each respective acquisition using the sum of the years’ digits accelerated method. The gross carrying amount of goodwill and the gross carrying amount and accumulated amortization of the CDI at September 30, 2024 and December 31, 2023 were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Carrying ​ Accumulated ​ Net Carrying ​ ​ Amount ​ Amortization ​ Amount ​ ​ (Dollars in thousands) September 30, 2024 ​ ​ ​ Goodwill ​ $ 14,135 ​ $ — ​ $ 14,135 Core deposit intangible ​ 21,938 ​ 7,453 ​ 14,485 Total goodwill and intangible assets ​ $ 36,073 ​ $ 7,453 ​ $ 28,620 December 31, 2023 ​ ​ ​ Goodwill ​ $ 14,135 ​ $ — ​ $ 14,135 Core deposit intangible ​ ​ 21,938 ​ 4,738 ​ 17,200 Total goodwill and intangible assets ​ $ 36,073 ​ $ 4,738 ​ $ 31,335 ​ The estimated aggregate future amortization expense over the next five years for the CDI is as follows at September 30, 2024: ​ ​ ​ ​ ​ (Dollars in thousands) ​ ​ For the three months ending December 31, 2024 ​ $ 854 For the year ending December 31, 2025 ​ 3,155 For the year ending December 31, 2026 ​ 2,739 For the year ending December 31, 2027 ​ 2,325 For the year ending December 31, 2028 ​ 1,909 ​

Derivatives and Hedging

Derivatives and Hedging
Derivatives and Hedging	Note 6: Derivatives and Hedging The Company is exposed to certain risks arising from both its business operations and economic conditions, including interest rate, liquidity, and credit risk. The Company uses derivative financial instruments as part of its risk management activities to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s existing credit derivatives result from participations of loan participation arrangements, and therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. Cash Flow Hedges of Interest Rate Risk The Company uses interest rate derivatives to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company may utilize interest rate swaps, including forwards, interest rate caps, floors, collars, corridors and swaptions as part of its interest rate risk management strategy. During the third quarter of 2024, the Company had interest rate swaps and a collar to hedge the variable cash flows associated with existing variable-rate debt and loan assets in place. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Interest rate collars designated as cash flow hedges involve payments of variable-rate amounts if interest rates rise above the cap strike rate on the contract and the receipt of variable-rate amounts if interest rates fall below the floor strike rate on the contract. During the first nine months of 2024, two cash flow hedges matured and two cash flow hedges were terminated. Derivatives that qualify as cash flow hedges and are designated as such include one instrument with a total notional value of $250 million at September 30, 2024, and five instruments with a total notional value of $340 million at December 31, 2023. For derivatives that qualify as cash flow hedges of interest rate risk and are designated as such, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Loss (“AOCI”) and subsequently reclassified into interest income or expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest income and expense as interest payments are received and made on the Company’s variable-rate assets and debt. The Company currently estimates that $0.5 million will be reclassified as a net decrease to net interest income during the next twelve months. These reclassifications are for active hedges, as well as amounts related to five hedged swaps that were terminated in 2022 and the two hedged swaps terminated in the first quarter of 2024, that continue to be recognized based on the original effective dates of the hedged transactions. The Company is hedging its exposure to the variability in future cash flows for forecasted transactions over a maximum period of 2.3 years. Non-designated Hedges Derivatives not designated as hedges are not speculative and result from a service provided to clients. The Company executes interest rate swaps with clients 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. Interest rate derivatives associated with this program do not meet the strict hedge accounting requirements and changes in the fair value of both the client derivatives and the offsetting derivatives are recognized directly in earnings. Swap fees earned upon origination and credit valuation adjustments that represent the risk of a counterparty’s default are reported on the consolidated statements of operations as swap fees and credit valuation adjustments, net. The effect of the Company’s derivative financial instruments gain (loss) is reported on the consolidated statements of cash flows within “other assets” and “other liabilities”. The Company had 50 and 46 swaps outstanding with an aggregate notional amount of $356 million and $307 million at September 30, 2024 and December 31, 2023, respectively. The Company’s existing credit derivatives result from participations in or out of interest rate swaps provided by or to external lenders as part of loan participation arrangements, and therefore, are not used to manage interest rate risk in the Company’s assets or liabilities.

Regulatory Matters
Regulatory Matters	Note 9: 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, 2024, the Company and the Bank met all capital adequacy requirements to which they are subject. The capital rules require the Company to maintain a 2.5% capital conservation buffer with respect to Common Equity Tier I capital, Tier I capital to risk-weighted assets, and total capital to risk-weighted assets, which is included in the column “Required to be Considered Adequately Capitalized” within the table below. A financial institution with a conservation buffer of less than the required amount is subject to limitations on capital distributions, including dividend payments and stock repurchases, as well as certain discretionary bonus payments to executive officers. The Company and the Bank opted to exclude AOCI from the regulatory capital calculations. As a result, changes in AOCI, net of tax, do not impact the Company’s or Bank’s regulatory capital ratios. ​ The Company’s and the Bank’s actual capital amounts and ratios as of September 30, 2024 and December 31, 2023 are presented in the following table: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Required to be Considered Required to be Considered ​ ​ Actual ​ Well Capitalized ​ Adequately Capitalized (1) ​ Amount Ratio Amount Ratio Amount Ratio ​ ​ (Dollars in thousands) September 30, 2024 ​ ​ ​ ​ Total Capital to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ $ 868,146 11.8 % ​ N/A N/A ​ $ 770,742 10.5 % Bank ​ 855,496 11.7 ​ $ 733,613 10.0 % 770,294 10.5 ​ Tier 1 Capital to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ 785,057 10.7 ​ N/A N/A ​ 623,934 8.5 ​ Bank ​ 772,407 10.5 ​ 586,891 8.0 ​ 623,571 8.5 ​ Common Equity Tier 1 to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ 776,142 10.6 ​ N/A N/A ​ 513,828 7.0 ​ Bank ​ 772,407 10.5 ​ 476,849 6.5 ​ 513,529 7.0 ​ Tier 1 Capital to Average Assets ​ ​ ​ ​ ​ Consolidated ​ 785,057 10.2 ​ N/A N/A ​ 307,189 4.0 ​ Bank ​ $ 772,407 10.1 % $ 384,094 5.0 % $ 307,275 4.0 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ Total Capital to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ $ 807,018 11.2 % ​ N/A N/A ​ $ 756,285 10.5 % Bank ​ 800,522 11.1 ​ $ 719,705 10.0 % 755,691 10.5 ​ Tier 1 Capital to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ 727,723 10.1 ​ N/A N/A ​ 612,231 8.5 ​ Bank ​ 721,227 10.0 ​ 575,764 8.0 ​ 611,750 8.5 ​ Common Equity Tier 1 to Risk-Weighted Assets ​ ​ ​ ​ Consolidated ​ 718,855 10.0 ​ N/A N/A ​ 504,190 7.0 ​ Bank ​ 721,227 10.0 ​ 467,809 6.5 ​ 503,794 7.0 ​ Tier 1 Capital to Average Assets ​ ​ ​ ​ Consolidated ​ 727,723 10.0 ​ N/A N/A ​ 292,517 4.0 ​ Bank ​ $ 721,227 9.9 % $ 365,675 5.0 % $ 292,540 4.0 % (1) Represents the minimum capital required for capital adequacy under Basel III.

Disclosure about Fair Value of Financial Instruments
Disclosure about Fair Value of Financial Instruments	Note 11: 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 value 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 list presents the assets and liabilities recognized in the accompanying consolidated statements of financial condition 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, 2024 and December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Description Valuation Hierarchy Level Where Fair Value Balance Can Be Found 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. ​ Level 2 ​ Note 2: Securities Derivatives Fair value of the interest rate swaps is obtained from independent pricing services based on quoted market prices for similar derivative contracts. ​ Level 2 ​ Note 6: Derivatives and ​ The following tables present the estimated fair values of the Company’s financial instruments at September 30, 2024 and December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2024 ​ ​ Carrying ​ Fair Value Measurements ​ Amount Level 1 Level 2 Level 3 ​ ​ (Dollars in thousands) Financial Assets ​ ​ ​ ​ Cash and cash equivalents ​ $ 236,937 ​ $ 236,937 ​ $ — ​ $ — Available-for-sale securities ​ 783,995 ​ — ​ 783,995 ​ — Loans, net of allowance for credit losses ​ 6,253,292 ​ — ​ — ​ 6,295,504 Restricted equity securities ​ 3,715 ​ — ​ — ​ 3,715 Interest receivable ​ 39,485 ​ — ​ 39,485 ​ — Equity securities ​ 7,305 ​ — ​ — ​ 7,305 Derivative assets ​ 6,720 ​ — ​ 6,720 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities ​ ​ ​ ​ Deposits ​ $ 6,634,276 ​ $ 900,794 ​ $ — ​ $ 5,791,397 Federal Home Loan Bank advances ​ 76,221 ​ — ​ 73,242 ​ — Other borrowings ​ 8,598 ​ — ​ 9,795 ​ — Interest payable ​ 22,316 ​ — ​ 22,316 ​ — Derivative liabilities ​ 9,742 ​ — ​ 9,742 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ Carrying ​ Fair Value Measurements ​ Amount Level 1 Level 2 Level 3 ​ ​ (Dollars in thousands) Financial Assets ​ ​ ​ ​ Cash and cash equivalents ​ $ 255,229 ​ $ 255,229 ​ $ — ​ $ — Available-for-sale securities ​ 766,653 ​ — ​ 766,653 ​ — Loans, net of allowance for credit losses ​ 6,054,228 ​ — ​ — ​ 6,036,887 Restricted equity securities ​ 3,950 ​ — ​ — ​ 3,950 Interest receivable ​ 37,294 ​ — ​ 37,294 ​ — Equity securities ​ 5,794 ​ — ​ — ​ 5,794 Derivative assets ​ 7,581 ​ — ​ 7,581 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial Liabilities ​ ​ ​ ​ Deposits ​ $ 6,491,276 ​ $ 990,458 ​ $ — ​ $ 5,547,203 Federal Home Loan Bank advances ​ 77,889 ​ — ​ 72,123 ​ — Other borrowings ​ 8,950 ​ — ​ 9,891 ​ — Interest payable ​ 18,529 ​ — ​ 18,529 ​ — Derivative liabilities ​ 13,594 ​ — ​ 13,594 ​ — ​ Nonrecurring Measurements The following tables present the fair value measurement on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at September 30, 2024 and December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ September 30, 2024 ​ ​ ​ ​ ​ Fair Value Measurements Using ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets for ​ Significant Other ​ Unobservable ​ ​ ​ ​ ​ Identical Assets ​ Observable Inputs ​ Inputs ​ Fair Value (Level 1) (Level 2) (Level 3) ​ ​ (Dollars in thousands) Collateral-dependent impaired loans ​ $ 823 ​ $ — ​ $ — ​ $ 823 Foreclosed assets held-for-sale ​ ​ 5,286 ​ ​ — ​ ​ — ​ ​ 5,286 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ ​ Fair Value Measurements Using ​ ​ ​ ​ ​ Quoted Prices in ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets for ​ Significant Other ​ Unobservable ​ ​ ​ ​ ​ Identical Assets ​ Observable Inputs ​ Inputs ​ Fair Value (Level 1) (Level 2) (Level 3) ​ ​ (Dollars in thousands) Collateral-dependent impaired loans $ 10,570 ​ $ — ​ $ — ​ $ 10,570 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 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 statements of financial condition, as well as the general classification of such assets pursuant to the valuation hierarchy.

Nature of Operations and Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying interim unaudited consolidated financial statements serve to update the CrossFirst Bankshares, Inc. Annual Report on Form 10-K for the year ended December 31, 2023 and include the consolidated accounts of Bankshares, the Bank, CFI, CFBSA I, LLC and CFBSA II, LLC (together, referred to herein as the “Company”). The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and where applicable, with general practices in the banking industry or guidelines prescribed by bank regulatory agencies. However, they may not include all information and notes necessary to constitute a complete set of financial statements under GAAP applicable to annual periods and accordingly should be read in conjunction with the financial information contained in the Company's most recent Annual Report on Form 10-K. The unaudited consolidated financial statements reflect all adjustments which are, in the opinion of management, necessary for a fair statement of the results presented. All such adjustments are of a normal recurring nature. All significant intercompany balances and transactions have been eliminated in consolidation. Certain reclassifications of prior years' amounts are made whenever necessary to conform to current period presentation. The results of operations for the interim period are not necessarily indicative of the results that may be expected for the full year or any other interim period. All amounts are in thousands, except share data, or as otherwise noted. GAAP requires management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses, and disclosures of contingent assets and liabilities. By their nature, estimates are based on judgment and available information. Management has made significant estimates in certain areas, such as the fair values of financial instruments, and the allowance for credit losses (“ACL”). Because of the inherent uncertainties associated with any estimation process and future changes in market and economic conditions, it is possible that actual results could differ significantly from those estimates. The Company's significant accounting policies followed in the preparation of the unaudited consolidated financial statements are disclosed in Note 1 of the audited financial statements and notes for the year ended December 31, 2023 and are contained in the Company's Annual Report on Form 10-K for that period. There have been no significant changes to the application of significant accounting policies since December 31, 2023.

Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting pronouncements not yet adopted by the Company In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires enhanced disclosures on both an annual and interim basis about significant segment expenses, including for companies with only one reportable segment. This ASU is effective on a retrospective basis for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company expects to adopt this ASU as of December 31, 2024 and include the required disclosures in a segment reporting footnote in its year-end financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures which requires updates to rate reconciliation disclosures and information on income taxes paid on an annual basis. This ASU is effective on a prospective basis with retrospective application permitted for annual periods beginning after December 15, 2024. The Company is evaluating the impact the adoption of this ASU will have on its consolidated financial statements and related disclosures. ​
