Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Nature of operations - Coastal Financial Corporation (“Corporation” or “Company”) is a registered bank holding company whose wholly owned subsidiaries are Coastal Community Bank (“Bank”) and Arlington Olympic LLC (“LLC”). The Company is a Washington state corporation that was organized in 2003. The Bank was incorporated and commenced operations in 1997 and is a Washington state-chartered commercial bank that is a member bank of the Federal Reserve system. Arlington Olympic LLC was formed in 2019 and owns the Company’s Arlington branch site, which the Bank leases from the LLC. We are headquartered in Everett, Washington, which by population is the largest city in, and the county seat of, Snohomish County. The Company’s business is conducted through three reportable segments: CCBX, the community bank and treasury & administration. The CCBX segment provides Banking as a Service (“BaaS”) that allows our broker dealers and digital financial service partners to offer their customers banking services. Through CCBX’s partners the Company is able to offer banking services and products across the nation.The community bank segment includes all community banking activities with a primary focus on providing a wide range of banking products and services to consumers and small to medium-sized businesses, professionals, and individuals in the broader Puget Sound region in the state of Washington through its 14 branches in Snohomish, Island and King Counties, and through the Internet and its mobile banking application. The treasury & administration segment includes treasury management, overall administration and all other aspects of the Company. The Bank’s deposits are insured in whole or in part by the Federal Deposit Insurance Corporation. The community bank’s loans and deposits are primarily within the greater Puget Sound area, while CCBX loans and deposits are dependent upon the partner’s market. The Bank’s primary funding source is deposits from customers. The Bank is subject to regulation and supervision by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and the Washington State Department of Financial Institutions Division of Banks. The Federal Reserve also has regulatory and supervisory authority over the Company. Financial statement presentation - The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim reporting requirements and with instructions to Form 10-Q and Article 10 of Regulation S-X, and therefore do not include all the information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual report on Form 10-K as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 16, 2023. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the entire year. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per-share amounts, which are presented in dollars. In the narrative footnote discussion, amounts are rounded to thousands and presented in dollars. In management’s opinion, all accounting adjustments necessary to accurately reflect the financial position and results of operations on the accompanying consolidated financial statements have been made. These adjustments include normal and recurring accruals considered necessary for a fair and accurate presentation. Principles of consolidation - The consolidated financial statements include the accounts of the Company, the Bank and the LLC. All significant intercompany accounts have been eliminated in consolidation. Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that its critical accounting policies include determining the allowance for credit losses, the valuation of the Company’s deferred tax assets, and fair value of financial instruments. Actual results could differ significantly from those estimates. Implementation of ASU 2016-13 - On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss with an expected loss methodology that is referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in certain leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require increases or decreases in credit losses be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believe it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis. The Company adopted ASC 326 using the modified retrospective method. Results for the reporting periods beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The day one CECL adjustment for community bank loans included a reduction of $310,000 to the community bank allowance in the first quarter of 2023 and a reduction of $340,000 related to the community bank unfunded commitment reserve in the first quarter of 2023. This was offset by an increase to the CCBX allowance for $4.2 million in the same period. With the mirror image approach accounting related to the credit enhancement for CCBX partner loans, there was a CECL day one increase to the indemnification asset in the amount of $4.5 million. Net, the day one impact to retained earnings for the Bank’s transition to CECL was an increase of $954,000 in the first quarter of 2023, excluding the impact of income taxes. Management has separately evaluated its held-to-maturity investment securities and determined that no loss reserves were required. Implementation of ASU 2022-02 - On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings ("TDR") and Vintage Disclosures. The ASU eliminated the accounting guidance for TDR loans by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU was effective upon adoption of ASU 2016-13 and was applied on a prospective basis. During the three and nine months ended September 30, 2023, the Company did not have any loans that were modified to borrowers experiencing financial difficulty. Accounting policy update – Allowance for Credit Losses - effective January 1, 2023 with the adoption of ASU 2016-13 Loans and unfunded commitments The allowance for credit losses ("ACL") is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL is evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool and whether it needs to evaluate the allowance on an individual basis. The Company must estimate expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. In estimating the life of the loan, the Company cannot extend the contractual term of the loan for expected extensions, renewals, and modifications, unless the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. Because expected credit losses are estimated over the contractual life adjusted for estimated prepayments, determination of the life of the loan may significantly affect the ACL. The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. • Community Bank Portfolio: The ACL calculation is derived from loan segments utilizing loan level information and relevant available information from internal and external sources related to past events and current conditions. In addition, the Company incorporates a reasonable and supportable forecast. • CCBX Portfolio: The Bank calculates the ACL on loans on an aggregate basis based on each partner and product level, segmenting the risk inherent in the CCBX portfolio based on qualitative and quantitative trends in the portfolio. Also included in the ACL are qualitative reserves to cover losses that are expected, but in the Company’s assessment may not be adequately represented in the quantitative method. For example, factors that the Company considers include environmental business conditions, borrower’s financial condition, credit rating and the volume and severity of past due loans and non-accrual loans. Based on this analysis, the Company records a provision for credit losses to maintain the allowance at appropriate levels. Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses expected to occur in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for credit losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations. The Company has elected to exclude accrued interest receivable from the amortized cost basis in its ACL calculation as accrued interest is written off in a timely manner when deemed uncollectable. For more information and discussion related to the allowance for credit losses on loans, see “ Note 4 - Loans and Allowance for Credit Losses” in the Consolidated Financial Statements. In addition to the ACL on loans held for investment, CECL requires a balance sheet liability for expected losses on unfunded commitments, which is recognized if both the following conditions are met: (1) the Company has a present contractual obligation to extend credit; and (2) the obligation is not unconditionally cancellable by the Company. Loan commitments may have a funded and unfunded portion, of which the liability for unfunded commitments is derived based upon the commitments to extend credit to a borrower (e.g., an estimate of expected credit losses is not established for unfunded portions of loan commitment that are unconditionally cancellable by the Company). The expected credit losses for funded portions are reported in the previously discussed ACL. The Company segments its unfunded commitment portfolio consistent with the ACL calculation, separating between unfunded lines and commitments to originate. The Company incorporates the probability of funding (i.e. estimate of utilization) for each segment and then utilizes the ACL loss rates for each segment on an aggregate basis to calculate the allowance for unfunded commitments Available-for-sale debt securities For available-for-sale debt securities with fair value below amortized cost, the security is considered impaired. When the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, then the Company assesses the impairment for potential expected credit losses. Impairment related to a credit loss is measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. The impairment is recognized by establishing an ACL through provision for credit losses. Impairment related to noncredit factors is recognized in accumulated other comprehensive income, net of applicable taxes. The Company evaluates AFS security impairment on a quarterly basis. Held-to-maturity debt securities For held-to-maturity debt securities, expected losses are evaluated and calculated on a collective basis for those securities which share risk characteristics. The Company aggregates similar securities and reports the security portfolio segments based on shared risk characteristics. The only segment included in the held-to-maturity portfolio are U.S. Agency Residential Mortgage Backed Securities which have an expected zero credit loss. The following table illustrates the impact of ASU 2016-13: January 1, 2023 As reported Pre-ASC 326 Impact of Assets: Allowance for credit losses $ 77,881 $ 74,029 $ 3,852 CCBX credit enhancement asset 57,842 53,377 4,465 Deferred tax asset 18,238 18,458 (220) Liabilities: Unfunded commitment reserve 634 974 (340) Shareholders' Equity: Retained earnings 120,732 119,998 734 Subsequent Events - The Company has evaluated events and transactions subsequent to September 30, 2023 for potential recognition or disclosure. Reclassifications - Certain amounts reported in prior quarters' consolidated financial statements may have been reclassified to conform to the current presentation with no effect on stockholders’ equity or net income.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent accounting standards	Recent accounting standards Recent Accounting Guidance In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as Secured Overnight Financing Rate. Entities can elect not to apply certain modification accounting requirements to contracts affected by what the guidance calls reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Also, entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met, and can make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective for all entities upon issuance through December 31, 2024. The LIBOR ceased to be published effective June 30, 2023. Beginning with rate adjustments that occur after June 30, 2023, our trust preferred subordinated debentures transitioned to an adjusted three-month CME Term SOFR index in accordance with the Federal Reserve final rule implementing the Adjustable Interest Rate Act. We have identified the loans that utilize LIBOR and they will transition to alternative reference rates at each loans respective reprice date. We no longer offer LIBOR indexed rates on newly originated loans. ASU 2020-04 and ASU 2021-01 are not expected to have a material impact on our consolidated financial statements.

Receivables [Abstract]
Loans and Allowance for Credit Losses	Loans and Allowance for Credit Losses During the quarter ended September 30, 2023, $285.0 million in CCBX loans were transferred to loans held for sale, with $320.9 million in loans sold. A portion of these loans were sold at par and a portion were sold with a gain on sale of $107,000. Pricing is dependent upon the agreement with the partner. The Company sells CCBX loans to manage loan portfolio size by partner and by loan category, with such limits established and documented in the relevant partner agreement. As of September 30, 2023 and December 31, 2022, there were no loans held for sale. The Company adopted the CECL methodology for measuring credit losses as of January 1, 2023. All disclosures as of and for the three and nine months ended September 30, 2023 are presented in accordance with Topic 326. The Company did not recast comparative financial periods and has presented those disclosures under previously applicable GAAP. The composition of the loan portfolio is as follows as of the periods indicated: September 30, 2023 (dollars in thousands; unaudited) Community Bank Commercial and industrial loans $ 158,232 Real estate loans: Construction, land and land development loans 167,686 Residential real estate loans 225,372 Commercial real estate loans 1,237,849 Consumer and other loans: Other consumer and other loans 2,483 Gross Community Bank loans receivable 1,791,622 CCBX Commercial and industrial loans: Capital call lines $ 114,174 All other commercial & industrial loans 58,869 Real estate loans: Residential real estate loans 251,775 Consumer and other loans: Credit cards 440,993 Other consumer and other loans 316,987 Gross CCBX loans receivable 1,182,798 Total gross loans receivable 2,974,420 Net deferred origination fees and premiums (7,385) Loans receivable $ 2,967,035 December 31, 2022 Consolidated (dollars in thousands; unaudited) Commercial and industrial loans $ 312,628 Real estate loans: Construction, land, and land development 214,055 Residential real estate 449,157 Commercial real estate 1,048,752 Consumer and other loans 608,771 Gross loans receivable 2,633,363 Net deferred origination fees and premiums (6,107) Loans receivable $ 2,627,256 Accrued interest on loans, which is excluded from the balances in the preceding table of loans receivable, was $21.3 million and $17.0 million at September 30, 2023 and December 31, 2022, respectively, and was included in accrued interest receivable on the Company's consolidated balance sheets. Included in commercial and industrial loans as of September 30, 2023 and December 31, 2022, is $114.2 million and $146.0 million, respectively in capital call lines, provided to venture capital firms through one of our BaaS clients. These loans are secured by the capital call rights and are individually underwritten to the Bank’s credit standards by our BaaS client and the underwriting is reviewed and approved by the Bank on every line/loan. Also included in commercial and industrial loans are Paycheck Protection Program (“PPP”) loans of $3.3 million at September 30, 2023 and $4.7 million at December 31, 2022. PPP loans are 100% guaranteed by the Small Business Administration (“SBA”). Consumer and other loans includes overdrafts of $3.3 million and $2.7 million at September 30, 2023 and December 31, 2022, respectively. Community bank overdrafts were $1.0 million and $94,000 at September 30, 2023 and December 31, 2022, respectively and CCBX overdrafts were $2.3 million and $2.6 million at September 30, 2023 and December 31, 2022. The Company has pledged loans totaling $927.0 million and $220.1 million at September 30, 2023 and December 31, 2022, respectively, for borrowing lines at the FHLB and FRB. Additional loans were pledged during the first six months of 2023 to significantly increase the borrowing capacity of the Bank in the event of a liquidity crisis. The balance of SBA and United States Department of Agriculture ("USDA") loans and participations sold and serviced for others totaled $9.1 million and $14.3 million at September 30, 2023 and December 31, 2022, respectively. The gross balance of Main Street Lending Program (“MSLP”) loans including participations to others, totaled $58.0 million at September 30, 2023 and December 31, 2022, with $3.1 million in MSLP loans on the balance sheet and included in commercial and industrial loans at September 30, 2023, and December 31, 2022. Servicing is retained on the gross balance. The Company, at times, purchases individual loans that meet its underwriting standards through the community bank at fair value as of the acquisition date. The Company held purchased loans with remaining balances that totaled The Company has purchased participation loans with remaining balances totaling $61.4 million and $63.9 million as of September 30, 2023 and December 31, 2022, respectively. These loans are included in the applicable loan category depending upon the collateral and purpose of the individual loan and underwritten to the Bank's credit standards. The Company purchased loans from a CCBX partner, at par, through agreements with that CCBX partner, and those loans had a remaining balance of $57.1 million as of September 30, 2023 and $157.4 million as of December 31, 2022. As of September 30, 2023, $50.1 million is included in consumer and other loans and $7.0 million is included in commercial and industrial loans, compared to $146.1 million in consumer and other loans and $11.3 million in commercial and industrial loans as of December 31, 2022. The following is a summary of the Company’s loan portfolio segments: Commercial and industrial loans – Commercial and industrial loans are secured by business assets including inventory, receivables and machinery and equipment of businesses located generally in the Company’s primary market area and capital calls on venture and investment funds. Also included in commercial and industrial loans are $58.9 million in unsecured CCBX partner loans. Loan types include PPP loans, revolving lines of credit, term loans, and loans secured by liquid collateral such as cash deposits or marketable securities. Also included in commercial and industrial loans are loans to other financial institutions. Risk arises primarily due to the difference between expected and actual cash flows of the borrowers. In addition, the recoverability of the Company’s investment in these loans is also dependent on other factors primarily dictated by the type of collateral securing these loans. The fair value of the collateral securing these loans may fluctuate as market conditions change. In the case of loans secured by accounts receivable, the recovery of the Company’s investment is dependent upon the borrower’s ability to collect amounts due from its customers. As of September 30, 2023, $114.2 million in outstanding CCBX capital call lines are included in commercial and industrial loans compared to $146.0 million at December 31, 2022. Capital call lines are provided to venture capital firms. These loans are secured by the capital call rights and are individually underwritten to the Bank’s credit standards by our CCBX partner and the underwriting is reviewed by the Bank on every line/loan. Construction, land and land development loans – The Company originates loans for the construction of 1-4 family, multifamily, and Commercial Real Estate (“CRE”) properties in the Company’s market area. Construction loans are considered to have higher risks due to construction completion and timing risk, the ultimate repayment being sensitive to interest rate changes, government regulation of real property and the availability of long-term financing. Additionally, economic conditions may impact the Company’s ability to recover its investment in construction loans, as adverse economic conditions may negatively impact the real estate market, which could affect the borrower’s ability to complete and sell the project. Additionally, the fair value of the underlying collateral may fluctuate as market conditions change. The Company occasionally originates land loans for the purpose of facilitating the ultimate construction of a home or commercial building. The primary risks include the borrower’s ability to pay and the inability of the Company to recover its investment due to a material decline in the fair value of the underlying collateral. Residential real estate loans – Residential real estate includes various types of loans for which the Company holds real property as collateral. Included in this segment are first and second lien single family loans, occasionally purchased by the Company to diversify its loan portfolio, and rental portfolios secured by one-to-four family homes. The primary risks of residential real estate loans include the borrower’s inability to pay, material decreases in the value of the collateral, and significant increases in interest rates which may make the loan unprofitable. As of September 30, 2023, $251.8 million in loans originated through CCBX partners are included in residential real estate loans, compared to $244.6 million at December 31, 2022. These home equity lines of credit are secured by residential real estate and are accessed by using a credit card. Home equity lines of credit are classified as residential real estate per regulatory guidelines. Commercial real estate (includes owner occupied and nonowner occupied) loans – Commercial real estate loans include various types of loans for which the Company holds real property as collateral. We have commercial mortgage loans totaling $360.5 million that are collateralized by owner-occupied real-estate and $519.1 million that are collateralized by non-owner-occupied real estate, as well as $347.2 million of multi-family residential loans and $11.2 million of farmland loans, as of September 30, 2023. The primary risks of commercial real estate loans include the borrower’s inability to pay, material decreases in the value of the collateralized real estate and significant increases in interest rates, which may make the real estate loan unprofitable. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. Consumer and other loans – The community bank originates a limited number of consumer loans, generally for banking customers only, which consist primarily of lines of credit, saving account secured loans, and auto loans. CCBX originates consumer loans including credit cards, consumer term loans and secured and unsecured lines of credit. This loan category includes overdrafts. Repayment of these loans is dependent on the borrower’s ability to pay and the fair value of the underlying collateral, if any. As of September 30, 2023, $758.0 million in CCBX loans are included in consumer and other loans compared to $607.0 million at December 31, 2022.

This is attributed to loans originated through CCBX lending partners which continue to accrue interest up to 120 or 180 days past due, dependent on product type. As of September 30, 2023 and December 31, 2022, $34.7 million and $25.5 million, respectively, of loans past due 90 days or more are covered by credit enhancements provided by our CCBX partners that protect the Bank against losses. The accrual of interest on community bank loans is discontinued when, in management’s opinion, the borrower may be unable to meet payments as they become due or when they are 90 days past due as to either principal or interest, unless they are well secured and in the process of collection. Installment/closed-end, and revolving/open-end consumer loans originated through CCBX lending partners will continue to accrue interest until 120 and 180 days past due, respectively and an allowance is recorded through provision expense for these expected losses. For installment/closed-end and revolving/open-end consumer loans originated through CCBX lending partners with balances outstanding beyond 120 days and 180 days past due, respectively, principal and capitalized interest outstanding is charged off against the allowance and accrued interest outstanding is reversed against interest income. These consumer loans are reported as nonperforming/substandard, 90 days or more days past due and still accruing. When loans are placed on nonaccrual status, all accrued interest is reversed from current period earnings. Payments received on nonaccrual loans are generally applied as a reduction to the loan principal balance. If the likelihood of further loss is removed, the Company will recognize interest on a cash basis only. Loans may be returned to accruing status if the Company believes that all remaining principal and interest is fully collectible and there has been at least six months of sustained repayment performance since the loan was placed on nonaccrual. An analysis of nonaccrual loans by category consisted of the following at the periods indicated: September 30, December 31, 2023 2022 Total Nonaccrual Nonaccrual with No ACL Total Nonaccrual (dollars in thousands; unaudited) Community Bank Commercial and industrial loans $ 2 $ 2 $ 113 Real estate loans: Construction, land and land development — — 66 Residential real estate 176 176 — Commercial real estate 7,145 7,145 6,901 Total nonaccrual loans $ 7,323 $ 7,323 $ 7,080 In some circumstances, the Company modifies loans in response to borrower financial difficulty, and generally provides for a temporary modification of loan repayment terms. In order for a modified loan to be considered for accrual status, the loan’s collateral coverage generally will be greater than or equal to 100% of the loan balance, the loan is current on payments, and the borrower must either prefund an interest reserve or demonstrate the ability to make payments from a verified source of cash flow for an extended period of time, usually at least six months in duration. No loans were modified for borrowers experiencing financial difficulty in the three and nine months ended September 30, 2023 and 2022. Credit Quality and Credit Risk Federal regulations require that the Company periodically evaluate the risks inherent in its loan portfolio. In addition, the Company’s regulatory agencies have authority to identify problem loans and, if appropriate, require them to be reclassified. The Company establishes loan grades for loans at the origination of the loan. Changes to community bank loan grades are considered at the time new information about the performance of a loan becomes available, including the receipt of updated financial information from the borrower and after loan reviews. For consumer loans, the Bank follows the Federal Financial Institutions Examination Council’s Uniform Retail Credit Classification and Account Management Policy for subsequent classification in the event of payment delinquencies or default. Typically, an individual loan grade will not be changed from the prior period unless there is a specific indication of credit deterioration or improvement. Credit deterioration is evidenced by delinquency, direct communications with the borrower or other borrower information that becomes known to management. Credit improvements are evidenced by known facts regarding the borrower or the collateral property. The Company classifies some loans as Watch or Other Loans Especially Mentioned (“OLEM”). Loans classified as Watch are performing assets but have elements of risk that require more monitoring than other performing loans and are reported in the OLEM column in the following table. Loans classified as OLEM are assets that continue to perform but have shown deterioration in credit quality and require close monitoring. There are three classifications for problem loans: Substandard, Doubtful, and Loss. Substandard loans have one or more defined weaknesses and are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Revolving (open-ended loans, such as credit cards) and installment (closed end) consumer loans originated through CCBX partners continue to accrue interest until they are charged-off at 120 days past due for installment loans (primarily unsecured loans to consumers) and 180 days past due for revolving loans (primarily credit cards) and are classified as substandard. Doubtful loans have the weaknesses of loans classified as Substandard, with additional characteristics that suggest the weaknesses make collection or recovery in full after liquidation of collateral questionable on the basis of currently existing facts, conditions, and values. There is a high possibility of loss in loans classified as Doubtful. A loan classified as Loss is considered uncollectible and of such little value that continued classification of the credit as a loan is not warranted. If a loan or a portion thereof is classified as Loss, it must be charged-off, meaning the amount of the loss is charged against the allowance for credit losses, thereby reducing that reserve. Management considers the guidance in ASC 310-20 when determining whether a modification, extension, or renewal of loan constitutes a current period origination. As of September 30, 2023 and December 31, 2022, based on the most recent analysis performed, the risk category of community bank loans by year of origination is as follows: Term Loans Amortized Cost Basis by Origination Year Community Bank 2023 2022 2021 2020 2019 Prior Revolving Loans Amortized Cost Basis Revolving Loans Converted To Term Total (dollars in thousands; unaudited) As of September 30, 2023 Commercial and industrial loans Risk rating Pass $ 12,798 $ 58,178 $ 16,236 $ 10,911 $ 13,843 $ 1,689 $ 40,923 $ 1,216 $ 155,794 Other Loan Especially Mentioned — — — 117 — — 2,319 — 2,436 Substandard — — — — — 2 — — 2 Doubtful — — — — — — — — — Total commercial and industrial $ 12,798 $ 58,178 $ 16,236 $ 11,028 $ 13,843 $ 1,691 $ 43,242 $ 1,216 $ 158,232 Current period gross write-offs $ — $ — $ — $ — $ — $ 46 $ — $ — $ 46 Real estate loans - Risk rating Pass $ 53,348 $ 59,253 $ 42,564 $ 3,103 $ 921 $ 1,620 $ 360 $ — $ 161,169 Other Loan Especially Mentioned — — 444 — — — — — 444 Substandard — — 3,148 2,325 — — 600 — 6,073 Doubtful — — — — — — — — — Total real estate loans - $ 53,348 $ 59,253 $ 46,156 $ 5,428 $ 921 $ 1,620 $ 960 $ — $ 167,686 Current period gross write-offs $ — $ — $ — $ — $ — $ — $ — $ — $ — Term Loans Amortized Cost Basis by Origination Year Community Bank 2023 2022 2021 2020 2019 Prior Revolving Loans Amortized Cost Basis Revolving Loans Converted To Term Total (dollars in thousands; unaudited) As of September 30, 2023 Real estate loans - Risk rating Pass $ 30,510 $ 41,717 $ 39,545 $ 30,465 $ 32,170 $ 24,063 $ 23,521 $ — $ 221,991 Other Loan Especially Mentioned — 1,102 2,028 33 — 42 — — 3,205 Substandard — — — — — — — 176 176 Doubtful — — — — — — — — — Total real estate loans - $ 30,510 $ 42,819 $ 41,573 $ 30,498 $ 32,170 $ 24,105 $ 23,521 $ 176 $ 225,372 Current period gross write-offs $ — $ — $ — $ — $ — $ — $ — $ — $ — Real estate loans - Risk rating Pass $ 195,094 $ 298,253 $ 201,342 $ 146,128 $ 127,437 $ 239,194 $ 8,403 $ 1,734 $ 1,217,585 Other Loan Especially Mentioned — 3,273 6,045 175 508 2,115 172 — 12,288 Substandard — — — 924 6,901 — 151 — 7,976 Doubtful — — — — — — — — — Total real estate loans - $ 195,094 $ 301,526 $ 207,387 $ 147,227 $ 134,846 $ 241,309 $ 8,726 $ 1,734 $ 1,237,849 Current period gross write-offs $ — $ — $ — $ — $ — $ — $ — $ — $ — Term Loans Amortized Cost Basis by Origination Year Community Bank 2023 2022 2021 2020 2019 Prior Revolving Loans Amortized Cost Basis Revolving Loans Converted To Term Total (dollars in thousands; unaudited) As of September 30, 2023 Consumer and other loans - Risk rating Pass $ 1,088 $ 286 $ 7 $ 687 $ 49 $ 216 $ 150 $ — $ 2,483 Other Loan Especially Mentioned — — — — — — — — — Substandard — — — — — — — — — Doubtful — — — — — — — — — Total consumer and other $ 1,088 $ 286 $ 7 $ 687 $ 49 $ 216 $ 150 $ — $ 2,483 Current period gross write-offs $ 16 $ — $ — $ — $ — $ — $ — $ — $ 16 Total community bank loans receivable Risk rating Pass $ 292,838 $ 457,687 $ 299,694 $ 191,294 $ 174,420 $ 266,782 $ 73,357 $ 2,950 $ 1,759,022 Other Loan Especially Mentioned — 4,375 8,517 325 508 2,157 2,491 — 18,373 Substandard — — 3,148 3,249 6,901 2 751 176 14,227 Doubtful — — — — — — — — — Total community bank loans $ 292,838 $ 462,062 $ 311,359 $ 194,868 $ 181,829 $ 268,941 $ 76,599 $ 3,126 $ 1,791,622 Current period gross write-offs $ 16 $ — $ — $ — $ — $ 46 $ — $ — $ 62 The Company considers the performance of the CCBX loan portfolio and its impact on the allowance for credit losses.

See Note 1, Description of Business and Summary of Significant Accounting Policies. As a result of implementing CECL, there was a one-time adjustment to the 2023 opening allowance balance of $3.9 million. CCBX loans have a higher level of expected losses than our community bank loans, which is reflected in the factors for the allowance for credit losses. Agreements with our CCBX partners provide for a credit enhancement which protects the Bank by reimbursing most losses. In accordance with accounting guidance, we estimate and record a provision for expected losses for these CCBX loans and reclassified negative deposit accounts. When the provision for CCBX credit losses and provision for unfunded commitments are recorded, a credit enhancement asset is also recorded on the balance sheet through noninterest income (BaaS credit enhancements). Expected losses are recorded in the allowance for credit losses. The credit enhancement asset is reduced when credit enhancement payments are received from the CCBX partner or taken from the partner's cash reserve account. CCBX partners provide for credit enhancements that provide protection to the Bank from credit and fraud losses by reimbursing the Bank for the losses. If the partner is unable to fulfill their contracted obligations then the Bank could be exposed to the loss of the reimbursement and credit enhancement income. In accordance with the program agreement for one CCBX partner, the Company is responsible for credit losses on approximately 10% of a $231.9 million loan portfolio that are without credit enhancement reimbursements. At September 30, 2023, 10% of this portfolio represented $23.2 million in loans. The partner is responsible for reimbursing credit losses on approximately 90% of this portfolio and for fraud losses on 100% of this portfolio. The Company earns 100% of the interest income on the aforementioned $23.2 million of loans.

Leases

Leases [Abstract]
Leases	Leases The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating lease right-of-use (“ROU”) assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. An operating lease ROU asset and operating lease liability will be recognized for any new operating leases at the commencement of the new lease. The Company’s leases do not provide an implicit interest rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities. The weighted average discount rate as of September 30, 2023 was 3.98%. The Company’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Company’s lease agreements do not contain any residual value guarantees. Operating leases with terms of 12 months or less are not included in ROU assets and operating lease liabilities recorded in the Company’s consolidated balance sheet. Operating lease terms include options to extend when it is reasonably certain that the Company will exercise such options, determined on a lease-by-lease basis. At September 30, 2023, lease expiration dates ranged from 5 months to 21.4 years, with additional renewal options on certain leases typically ranging from 5 to 10 years. At September 30, 2023, the weighted average remaining lease term inclusive of renewal options that the Company is reasonably certain to renew for the Company’s operating leases was 9.2 years. Rental expense for operating leases is recognized on a straight-line basis over the lease term and amounted to $292,000 and $933,000, respectively, for the three and nine months ended September 30, 2023, and $351,000 and $1.0 million respectively, for the three and nine months ended September 30, 2022. Variable lease components, such as inflation adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. The following table presents the minimum annual lease payments under the terms of these leases, inclusive of renewal options that the Company is reasonably certain to renew, at September 30, 2023: (dollars in thousands; unaudited) September 30, October 1 to December 31, 2023 $ 257 2024 1,016 2025 974 2026 977 2027 913 2028 and thereafter 3,456 Total lease payments 7,593 Less: amounts representing interest 1,272 Present value of lease liabilities $ 6,321 The following table presents the components of total lease expense and operating cash flows for the three and nine months ended September 30, 2023 and 2022: Three Months Ended Nine Months Ended September 30, September 30, September 30, September 30, (dollars in thousands; unaudited) Lease expense: Operating lease expense $ 251 $ 320 $ 819 $ 961 Variable lease expense 69 52 173 137 Total lease expense (1) $ 320 $ 372 $ 992 $ 1,098 Cash paid: Cash paid reducing operating lease liabilities $ 320 $ 371 $ 1,013 $ 1,090 (1) Included in net occupancy expense in the Condensed Consolidated Statements of Income (unaudited).

Stock-Based Compensation

Stock-Based Compensation	9 Months Ended
	Sep. 30, 2023
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	Stock-Based Compensation Stock Options and Restricted Stock The 2018 Coastal Financial Corporation Omnibus Plan (the "2018 Plan") authorizes the Company to grant awards, including but not limited to, stock options, restricted stock units, and restricted stock awards, to eligible employees, directors or individuals that provide service to the Company, up to an aggregate of 500,000 shares of common stock. On May 24, 2021, the Company’s shareholders approved the First Amendment to the 2018 Plan, which increased the authorized plan shares by 600,000. The 2018 Plan replaced the 2006 Plan for new awards. Existing awards will vest under the terms granted and no further awards will be granted under these prior plans. Shares available to be granted under the 2018 plan were 427,419 at September 30, 2023. Stock Option Awards The fair value of each option award is estimated on the date of grant using the Black-Scholes option pricing model. Expected volatilities are based on historical volatility of the Company’s stock and other factors. The Company uses the vesting term and contractual life to determine the expected life. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Compensation expense related to unvested stock option awards is reversed at date of forfeiture. There were no new stock options granted in the nine months ended September 30, 2023 and 2022. A summary of stock option activity under the 2018 Plan and 2006 Plan during the nine months ended September 30, 2023: Options Shares Weighted- Weighted- Aggregate (dollars in thousands, except per share amounts; unaudited) Outstanding at December 31, 2022 438,103 $ 8.79 4.1 $ 16,968 Granted — — Exercised (81,744) 7.34 $ 2,396 Expired — — Forfeited — — Outstanding at September 30, 2023 356,359 $ 9.12 3.7 $ 12,040 Vested or expected to vest at September 30, 2023 356,359 $ 9.12 3.7 $ 12,040 Exercisable at September 30, 2023 177,510 $ 8.65 3.4 $ 6,082 The total or aggregate intrinsic value (which is the amount by which the stock price exceeds the exercise price) of options exercised during the three and nine months ended September 30, 2023 was $59,000 and $2.4 million, respectively. The total or aggregate intrinsic value of options exercised during the three and nine months ended September 30, 2022 was $186,000 and $1.6 million, respectively. As of September 30, 2023, there was $861,000 of total unrecognized compensation cost related to nonvested stock options granted under the 2018 Plan and 2006 Plan. Total unrecognized compensation costs are adjusted for unvested forfeitures. The Company expects to recognize that cost over a remaining weighted-average period of approximately 3.9 years. Compensation expense recorded related to stock options was $61,000 and $261,000 respectively, for the three and nine months ended September 30, 2023 and $65,000 and $253,000 respectively, for the three and nine months ended September 30, 2022. Restricted Stock Units In the first quarter of 2023, the Company granted 73,611 restricted stock units ("RSUs") under the 2018 Plan to employees, which vest ratably over 4 years and 1,084 RSUs to an employee which vest ratably over 5 years. In the second quarter of 2023, the Company granted 9,827 RSUs to employees, which vest ratably over 5 years. In the third quarter of 2023, the Company granted 4,000 RSUs to employees which vest ratably over 3 years and 2,150 RSUs which vest ratably over 5 years. RSUs provide for an interest in Company common stock to the recipient, the underlying stock is not issued until certain conditions are met. Vesting requirements include time-based, performance-based, or market-based conditions. Recipients of RSUs do not pay any cash consideration to the Company for the units and the holders of the restricted units do not have voting rights. The fair value of time-based and performance-based units is equal to the fair market value of the Company’s common stock on the grant date. The fair value of market-based units is estimated on the grant date using the Monte Carlo simulation model. Compensation expense is recognized over the vesting period that the awards are based. RSUs are nonparticipating securities. As of September 30, 2023, there was $10.2 million of total unrecognized compensation cost related to nonvested RSUs. The Company expects to recognize that cost over the remaining weighted-average vesting period of approximately 3.9 years. Compensation expense recorded related to RSUs was $735,000 and $2.2 million respectively, for the three and nine months ended September 30, 2023 and $518,000 and $1.3 million respectively, for the three and nine months ended September 30, 2022. A summary of the Company’s nonvested RSUs at September 30, 2023 and changes during the nine month period is presented below: Nonvested shares - RSUs Shares Weighted- Total or Aggregate (dollars in thousands, except per share amounts; unaudited) Nonvested shares at December 31, 2022 380,151 $ 28.61 $ 7,187 Granted 90,672 $ 42.61 Forfeited (8,807) $ 38.62 Vested (46,020) $ 30.56 Nonvested shares at September 30, 2023 415,996 $ 31.23 $ 4,857 Restricted Stock Awards Employees There were no new restricted stock awards granted in the nine months ended September 30, 2023. The fair value of restricted stock awards is equal to the fair value of the Company’s stock at the date of grant. Compensation expense is recognized over the vesting period that the awards are based. Restricted stock awards are participating securities. As of September 30, 2023, there was $39,000 of total unrecognized compensation cost related to nonvested restricted stock awards. The Company expects to recognize that cost over the remaining weighted-average vesting period of approximately 4.3 years. Compensation expense recorded related to restricted stock awards was $2,000 and $7,000 respectively, for the three and nine months ended September 30, 2023 and $2,000 and $7,000 respectively, for the three and nine months ended September 30, 2022. Director’s Stock Compensation Under the 2018 Plan, eligible directors are granted stock with a total market value of approximately $45,000, and the Board Chair is granted stock with a total market value of approximately $75,000. Committee chairs receive additional stock in an amount that varies depending upon the nature and frequency of the committee meetings. The audit committee chair receives additional stock with a market value of approximately $10,000, non-financial risk and compensation committee chairs receive additional stock with a market value of approximately $7,500, and the asset liability & investment, credit and nominating & governance chairs receive additional stock with a market value of approximately $5,000. Stock is granted as of each annual meeting date and vest one day prior to the next annual meeting date. During the vesting period, the grants are considered participating securities. As of September 30, 2023, there was $313,000 of total unrecognized compensation expense related to director restricted stock awards which the Company expects to recognize over the remaining average vesting period of approximately eight months. Director compensation expense recorded related to the 2018 Plan totaled $120,000 and $312,000 respectively, for the three and nine months ended September 30, 2023 and $98,000 and $196,000 respectively, for the three and nine months ended September 30, 2022.

Fair value is defined as 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 (that is, not a forced liquidation or distressed sale). GAAP establishes a consistent framework for measuring fair value and disclosure requirements about fair value measurements. Among other things, the accounting standard requires the reporting entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s estimates for market assumptions. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices in active markets for identical instruments. An active market is a market in which transactions occur with sufficient frequency and volume to provide pricing information on an ongoing basis. A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. • Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data. • Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation; also includes observable inputs from nonbinding single dealer quotes not corroborated by observable market data. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for certain financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. Items measured at fair value on a recurring basis – The following fair value hierarchy table presents information about the Company’s assets that are measured at fair value on a recurring basis at the dates indicated: Level 1 Level 2 Level 3 Total (dollars in thousands; unaudited) September 30, 2023 Available-for-sale U.S. Treasury securities $ 98,644 $ — $ — $ 98,644 U.S. Agency collateralized mortgage obligations — 45 — 45 Municipals — 250 — 250 $ 98,644 $ 295 $ — $ 98,939 December 31, 2022 Available-for-sale U.S. Treasury securities $ 97,015 $ — $ — $ 97,015 U.S. Agency collateralized mortgage obligations — 51 — 51 U.S. Agency residential mortgage-backed securities — 1 — 1 Municipals — 250 — 250 $ 97,015 $ 302 $ — $ 97,317 The following methods were used to estimate the fair value of the class of financial instruments above: Investment securities - The fair value of securities is based on quoted market prices, pricing models, quoted prices of similar securities, independent pricing sources, and discounted cash flows. Limitations: The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2023 and December 31, 2022. The factors used in the fair values estimates are subject to change subsequent to the dates the fair value estimates are completed, therefore, current estimates of fair value may differ significantly from the amounts presented herein. Items measured at fair value on a nonrecurring basis – The following table presents financial assets and liabilities measured at fair value on a nonrecurring basis and the level within the fair value hierarchy of the fair value measurements for those assets at the dates indicated: Level 1 Level 2 Level 3 Total (dollars in thousands; unaudited) September 30, 2023 Equity securities $ — $ — $ 2,572 $ 2,572 Total $ — $ — $ 2,572 $ 2,572 December 31, 2022 Impaired loans $ — $ — $ 7,080 $ 7,080 Equity securities — — 2,572 2,572 Total $ — $ — $ 9,652 $ 9,652 The amounts disclosed above represent the fair values at the time the nonrecurring fair value measurements were made, and not necessarily the fair value as of the dates reported on. Individually evaluated loans - Fair values for individually evaluated loans are estimated using the fair value of the collateral less selling costs if the loan results in a Level 3 classification. Individually evaluated loan amounts are initially valued at the lower of cost or fair value. Individually evaluated loans carried at fair value generally receive specific allocations of the allowance for credit losses. For collateral dependent real estate loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional credit losses and adjusted accordingly. The estimated fair values of financial instruments disclosed above follow the guidance in ASU 2016-01 which prescribes an “exit price” approach in estimating and disclosing fair value of financial instruments incorporating discounts for credit, liquidity, and marketability factors. Valuation is measured based on the fair value of the underlying collateral or the discounted cash expected future cash flows. Subsequent changes in the value of loans are included within the provision for credit losses - loans in the same manner in which it initially was recognized or as a reduction in the provision that would otherwise be reported. Loans are evaluated quarterly to determine if valuation adjustments should be recorded. The need for valuation adjustments arises when observable market prices or current appraised values of collateral indicate a shortfall in collateral value compared to current carrying values of the related loan. If the Company determines that the value of the individually evaluated loan is less than the carrying value of the loan, the Company either establishes an reserve as a specific component of the allowance for credit losses or charges off that amount. These valuation adjustments are considered nonrecurring fair value adjustments. Equity securities – The Company measures equity securities without readily determinable fair values at cost less impairment (if any), plus or minus observable price changes from an identical or similar investment of the same issuer, with price changes recognized in earnings. Assets measured at fair value using significant unobservable inputs (Level 3) The following table presents the carrying value of equity securities without readily determinable fair values, as of September 30, 2023, with adjustments recorded during the periods presented for those securities with observable price changes, if applicable.

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting As defined in ASC 280, Segment Reporting , an operating segment is a component of an enterprise that engages in business activities from which it may earn revenues and incur expenses, whose operating results are regularly reviewed by the enterprise’s chief operating decision makers to make decisions about resources to be allocated to the segment and assess its performance, and for which discrete financial information is available. We evaluate performance based on an internal performance measurement accounting system, which provides line of business results. This system uses various techniques to assign balance sheet and income statement amounts to the business segments, including allocations of income and expense. A primary objective of this measurement system and related internal financial reporting practices are to produce consistent results that reflect the underlying financial impact of the segments on the Company and to provide a basis of support for strategic decision making. The accounting policies applicable to our segments are those that apply to our preparation of the accompanying Consolidated Financial Statements. Based on these criteria, we have identified three segments: the community bank, CCBX, and treasury & administration. The community bank segment includes all community banking activities, with a primary focus of the community bank is on providing a wide range of banking products and services to consumers and small to medium sized businesses in the broader Puget Sound region in the state of Washington and through the Internet and our mobile banking application. We currently operate 14 full-service banking locations, 12 of which are located in Snohomish County, where we are the largest community bank by deposit market share, and two of which are located in neighboring counties (one in King County and one in Island County). The CCBX segment provides banking as a service (“BaaS”) that allows our broker-dealer and digital financial service partners to offer their customers banking services. The CCBX segment has 22 partners as of September 30, 2023. The treasury & administration segment includes investments, debt and other reporting items that are not specific to the community bank or CCBX segments. The management accounting policies and processes utilized in compiling segment financial information are highly subjective and, unlike financial accounting, are not based on authoritative guidance similar to GAAP. As a result, reported segments and the financial information of the reported segments are not necessarily comparable with similar information reported by other financial institutions. Additionally, because of the interrelationships of the various segments, the information presented is not indicative of how the segments would perform if they operated as independent entities. Changes in management structure or allocation methodologies and procedures may result in future changes to previously reported segment financial data. Furthermore, changes in management structure or allocation methodologies and procedures may result in changes in reported segment financial data. The Company continues to evaluate its methodology on allocating items to the Company’s various segments to support strategic business decisions by the Company’s executive leadership. Income and expenses that are specific to a segment are directly posted to each segment.

Accounting Policies [Abstract]
Nature of operations	Nature of operations - Coastal Financial Corporation (“Corporation” or “Company”) is a registered bank holding company whose wholly owned subsidiaries are Coastal Community Bank (“Bank”) and Arlington Olympic LLC (“LLC”). The Company is a Washington state corporation that was organized in 2003. The Bank was incorporated and commenced operations in 1997 and is a Washington state-chartered commercial bank that is a member bank of the Federal Reserve system. Arlington Olympic LLC was formed in 2019 and owns the Company’s Arlington branch site, which the Bank leases from the LLC. We are headquartered in Everett, Washington, which by population is the largest city in, and the county seat of, Snohomish County. The Company’s business is conducted through three reportable segments: CCBX, the community bank and treasury & administration. The CCBX segment provides Banking as a Service (“BaaS”) that allows our broker dealers and digital financial service partners to offer their customers banking services. Through CCBX’s partners the Company is able to offer banking services and products across the nation.The community bank segment includes all community banking activities with a primary focus on providing a wide range of banking products and services to consumers and small to medium-sized businesses, professionals, and individuals in the broader Puget Sound region in the state of Washington through its 14 branches in Snohomish, Island and King Counties, and through the Internet and its mobile banking application. The treasury & administration segment includes treasury management, overall administration and all other aspects of the Company. The Bank’s deposits are insured in whole or in part by the Federal Deposit Insurance Corporation. The community bank’s loans and deposits are primarily within the greater Puget Sound area, while CCBX loans and deposits are dependent upon the partner’s market. The Bank’s primary funding source is deposits from customers. The Bank is subject to regulation and supervision by the Board of Governors of the Federal Reserve System (the “Federal Reserve”) and the Washington State Department of Financial Institutions Division of Banks. The Federal Reserve also has regulatory and supervisory authority over the Company.
Financial statement presentation	Financial statement presentation - The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim reporting requirements and with instructions to Form 10-Q and Article 10 of Regulation S-X, and therefore do not include all the information and notes included in the annual consolidated financial statements in conformity with GAAP. These interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company’s audited consolidated financial statements and accompanying notes included in the Company’s Annual report on Form 10-K as filed with the U.S. Securities and Exchange Commission (“SEC”) on March 16, 2023. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the entire year. Amounts presented in the consolidated financial statements and footnote tables are rounded and presented in thousands of dollars except per-share amounts, which are presented in dollars. In the narrative footnote discussion, amounts are rounded to thousands and presented in dollars.
Principles of consolidation	Principles of consolidation - The consolidated financial statements include the accounts of the Company, the Bank and the LLC. All significant intercompany accounts have been eliminated in consolidation.
Estimates	Estimates - The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management believes that its critical accounting policies include determining the allowance for credit losses, the valuation of the Company’s deferred tax assets, and fair value of financial instruments. Actual results could differ significantly from those estimates.
Implementation of ASUs	Implementation of ASU 2016-13 - On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments — Credit Losses (Topic 326) : Measurement of Credit Losses on Financial Instruments, which replaces the incurred loss with an expected loss methodology that is referred to as the current expected credit loss ("CECL") methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized costs, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in certain leases. In addition, ASC 326 made changes to the accounting for available-for-sale debt securities. One such change is to require increases or decreases in credit losses be presented as an allowance rather than as a write-down on available-for-sale debt securities management does not intend to sell or believe it is more likely than not the Company will be required to sell the security before recovery of the amortized cost basis. The Company adopted ASC 326 using the modified retrospective method. Results for the reporting periods beginning after January 1, 2023 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The day one CECL adjustment for community bank loans included a reduction of $310,000 to the community bank allowance in the first quarter of 2023 and a reduction of $340,000 related to the community bank unfunded commitment reserve in the first quarter of 2023. This was offset by an increase to the CCBX allowance for $4.2 million in the same period. With the mirror image approach accounting related to the credit enhancement for CCBX partner loans, there was a CECL day one increase to the indemnification asset in the amount of $4.5 million. Net, the day one impact to retained earnings for the Bank’s transition to CECL was an increase of $954,000 in the first quarter of 2023, excluding the impact of income taxes. Management has separately evaluated its held-to-maturity investment securities and determined that no loss reserves were required. Implementation of ASU 2022-02 - On January 1, 2023, the Company adopted ASU 2022-02, Financial Instruments - Credit Losses (Topic 326): Troubled Debt Restructurings ("TDR") and Vintage Disclosures. The ASU eliminated the accounting guidance for TDR loans by creditors while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. Additionally, the ASU requires public business entities to disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases. This ASU was effective upon adoption of ASU 2016-13 and was applied on a prospective basis. During the three and nine months ended September 30, 2023, the Company did not have any loans that were modified to borrowers experiencing financial difficulty. Accounting policy update – Allowance for Credit Losses - effective January 1, 2023 with the adoption of ASU 2016-13 Loans and unfunded commitments The allowance for credit losses ("ACL") is an estimate of the expected credit losses on financial assets measured at amortized cost. The ACL is evaluated and calculated on a collective basis for those loans which share similar risk characteristics. At each reporting period, the Company evaluates whether the loans in a pool continue to exhibit similar risk characteristics as the other loans in the pool and whether it needs to evaluate the allowance on an individual basis. The Company must estimate expected credit losses over the loans’ contractual terms, adjusted for expected prepayments. In estimating the life of the loan, the Company cannot extend the contractual term of the loan for expected extensions, renewals, and modifications, unless the extension or renewal options are included in the contract at the reporting date and are not unconditionally cancellable by the Company. Because expected credit losses are estimated over the contractual life adjusted for estimated prepayments, determination of the life of the loan may significantly affect the ACL. The Company has chosen to segment its portfolio consistent with the manner in which it manages the risk of the type of credit. • Community Bank Portfolio: The ACL calculation is derived from loan segments utilizing loan level information and relevant available information from internal and external sources related to past events and current conditions. In addition, the Company incorporates a reasonable and supportable forecast. • CCBX Portfolio: The Bank calculates the ACL on loans on an aggregate basis based on each partner and product level, segmenting the risk inherent in the CCBX portfolio based on qualitative and quantitative trends in the portfolio. Also included in the ACL are qualitative reserves to cover losses that are expected, but in the Company’s assessment may not be adequately represented in the quantitative method. For example, factors that the Company considers include environmental business conditions, borrower’s financial condition, credit rating and the volume and severity of past due loans and non-accrual loans. Based on this analysis, the Company records a provision for credit losses to maintain the allowance at appropriate levels. Determining the amount of the allowance is considered a critical accounting estimate, as it requires significant judgment and the use of subjective measurements, including management’s assessment of overall portfolio quality. The Company maintains the allowance at an amount the Company believes is sufficient to provide for estimated losses expected to occur in the Company’s loan portfolio at each balance sheet date, and fluctuations in the provision for credit losses may result from management’s assessment of the adequacy of the allowance. Changes in these estimates and assumptions are possible and may have a material impact on the Company’s allowance, and therefore the Company’s financial position, liquidity or results of operations. The Company has elected to exclude accrued interest receivable from the amortized cost basis in its ACL calculation as accrued interest is written off in a timely manner when deemed uncollectable. For more information and discussion related to the allowance for credit losses on loans, see “ Note 4 - Loans and Allowance for Credit Losses” in the Consolidated Financial Statements. In addition to the ACL on loans held for investment, CECL requires a balance sheet liability for expected losses on unfunded commitments, which is recognized if both the following conditions are met: (1) the Company has a present contractual obligation to extend credit; and (2) the obligation is not unconditionally cancellable by the Company. Loan commitments may have a funded and unfunded portion, of which the liability for unfunded commitments is derived based upon the commitments to extend credit to a borrower (e.g., an estimate of expected credit losses is not established for unfunded portions of loan commitment that are unconditionally cancellable by the Company). The expected credit losses for funded portions are reported in the previously discussed ACL. The Company segments its unfunded commitment portfolio consistent with the ACL calculation, separating between unfunded lines and commitments to originate. The Company incorporates the probability of funding (i.e. estimate of utilization) for each segment and then utilizes the ACL loss rates for each segment on an aggregate basis to calculate the allowance for unfunded commitments Available-for-sale debt securities For available-for-sale debt securities with fair value below amortized cost, the security is considered impaired. When the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, then the Company assesses the impairment for potential expected credit losses. Impairment related to a credit loss is measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. The impairment is recognized by establishing an ACL through provision for credit losses. Impairment related to noncredit factors is recognized in accumulated other comprehensive income, net of applicable taxes. The Company evaluates AFS security impairment on a quarterly basis. Held-to-maturity debt securities For held-to-maturity debt securities, expected losses are evaluated and calculated on a collective basis for those securities which share risk characteristics. The Company aggregates similar securities and reports the security portfolio segments based on shared risk characteristics. The only segment included in the held-to-maturity portfolio are U.S. Agency Residential Mortgage Backed Securities which have an expected zero credit loss.

Recent Accounting Guidance Not Yet Effective	Recent Accounting Guidance In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting , to provide temporary optional expedients and exceptions to the U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates, such as Secured Overnight Financing Rate. Entities can elect not to apply certain modification accounting requirements to contracts affected by what the guidance calls reference rate reform, if certain criteria are met. An entity that makes this election would not have to remeasure the contracts at the modification date or reassess a previous accounting determination. Also, entities can elect various optional expedients that would allow them to continue applying hedge accounting for hedging relationships affected by reference rate reform, if certain criteria are met, and can make a one-time election to sell and/or reclassify held-to-maturity debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective for all entities upon issuance through December 31, 2024. The LIBOR ceased to be published effective June 30, 2023. Beginning with rate adjustments that occur after June 30, 2023, our trust preferred subordinated debentures transitioned to an adjusted three-month CME Term SOFR index in accordance with the Federal Reserve final rule implementing the Adjustable Interest Rate Act. We have identified the loans that utilize LIBOR and they will transition to alternative reference rates at each loans respective reprice date. We no longer offer LIBOR indexed rates on newly originated loans. ASU 2020-04 and ASU 2021-01 are not expected to have a material impact on our consolidated financial statements.
