COASTAL FINANCIAL CORP

COASTAL FINANCIAL CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

Note 1 -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. The LLC was formed in 2019 and owns the Company’s Arlington branch site, which the Bank leases from the LLC.

The Company operates through the Bank and is headquartered in Everett, Washington, which by population is the largest city in Snohomish County. The Company’s business is conducted through three reportable segments: The community bank, CCBX and treasury & administration. The 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 digital financial service providers, companies and brands to offer their customers banking services. The CCBX segment had a total of 29 partners, at varying stages, as of June 30, 2025. The treasury & administration segment includes investments, debt and other reporting items that are not specific to the community bank or CCBX segments.

The Bank’s deposits are insured in whole or in part by the Federal Deposit Insurance Corporation (“FDIC”). The community bank’s loans and deposits are primarily within the greater Puget Sound region, 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 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 17, 2025. Operating results for the three and six months ended June 30, 2025 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.

Subsequent Events - The Company has evaluated events and transactions subsequent to June 30, 2025 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.

Note 2 -Recent accounting standards

Recent Accounting Guidance

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to provide financial statement users with more disaggregated expense information about a public entity’s reportable segments. The ASU addresses the concern that more segment information is needed, including allowing the disclosure of multiple measures of segment profit or loss, requiring the disclosure of significant segment expenses, and requiring the qualitative disclosure of other segment items. This ASU is effective for all entities for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024 and was implemented by the Company as of the fiscal year ended December 31, 2024.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, requiring a public business entity to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. The standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. The Company expects this ASU to only impact its disclosure requirements and does not expect the adoption of this ASU to have a material impact on its business operations or Consolidated Statements of Financial Condition.

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, requiring public companies to disclose, in the notes to financial statements, specified information about certain costs and expenses at each interim and annual reporting period. The amendments in this ASU are effective for fiscal years beginning after December 15, 2026, with early adoption permitted. The Company does not expect the adoption of this ASU to have a material impact on its business operations or Consolidated Statements of Financial Condition.

Note 3 -Investment Securities

The following table summarizes the amortized cost, fair value, and allowance for credit losses and the corresponding amounts of gross unrealized gains and losses of available-for-sale securities recognized in accumulated other comprehensive income (loss) and gross unrecognized gains and losses of held-to-maturity securities:

Accrued interest on available-for-sale securities was less than $1,000 at June 30, 2025 and December 31, 2024, accrued interest on held-to-maturity securities was $210,000 and $218,000 at June 30, 2025 and December 31, 2024, respectively. Accrued interest on securities is excluded from the balances in the preceding table of securities receivable, and is included in accrued interest receivable on the Company's consolidated balance sheets.

The amortized cost and fair value of debt securities at June 30, 2025, by contractual maturity, are shown below. Currently, the portfolio consists of mortgage-backed securities and collateralized mortgage obligations which are not due at a single maturity date. Expected maturities will differ from contractual maturities because issuers or the underlying borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Investments in debt securities with an amortized cost of $5.1 million at June 30, 2025 and $19.2 million as of December 31, 2024, were pledged to secure public deposits and for other purposes as required or permitted by law and an additional $36.4 million and $24.0 million in securities were pledged for borrowing lines at June 30, 2025 and December 31, 2024, respectively.

During the six months ended June 30, 2025, no securities matured andno securities were purchased.

There wereno sales of securities during the six months ended June 30, 2025 or 2024.

There were eight securities with a $334,000 unrealized loss as of June 30, 2025. There were sixteen securities with a $732,000 unrealized loss as of December 31, 2024. The following table shows the investments’ gross unrealized losses and fair values, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position for which an allowance for credit losses has not been recorded:

Management has evaluated the above securities and does not believe that any individual unrealized loss as of June 30, 2025, will be recognized into income. Unrealized losses have not been recognized into income because management does not intend to sell and does not expect it will be required to sell the investments. The decline in fair value is largely due to changes in market conditions and interest rates, rather than credit quality. The fair value is expected to recover as the underlying securities in the portfolio approach maturity date and market conditions improve. Management believes there is a high probability of collecting all contractual amounts due, because all of the securities in the portfolio are backed by government agencies or government sponsored enterprises. However, a recovery in value may not occur for some time, if at all, and may be delayed for greater than theone year time horizon or perhaps even until maturity. Based on management's analysis no allowance for credit losses was required on these securities.

Note 4 -Loans and Allowance for Credit Losses

Loans Held for Sale

During the six months ended June 30, 2025, $2.08 billion in CCBX loans were transferred to loans held for sale, with $2.04 billion in loans sold. These loans were sold at par. The Company sells CCBX loans to manage loan portfolio size by partner and by loan category. Partner loan limits are established and documented in the relevant partner agreement. There were $60.5 million loans held for sale as of June 30, 2025 and $20.6 million loans held for sale as of December 31, 2024.

Loans Held for Investment

The composition of the loan portfolio is as follows as of the periods indicated:

Accrued interest on loans, which is excluded from the balances in the preceding table of loans receivable, was $20.2 million and $20.5 million at June 30, 2025 and December 31, 2024, respectively, and was included in accrued interest receivable on the Company's consolidated balance sheets. Accrued interest on loans is net of an allowance of $602,000 andzero at June 30, 2025 and December 31, 2024, respectively.

Included in commercial and industrial loans as of June 30, 2025 and December 31, 2024, is $199.7 million and $109.0 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 by the Bank on every line/loan.

Consumer and other loans includes overdrafts of $14.6 million and $7.4 million at June 30, 2025 and December 31, 2024, respectively. Community bank overdrafts were $18,000 and $147,000 at June 30, 2025 and December 31, 2024, respectively and CCBX overdrafts were $14.6 million and $7.3 million at June 30, 2025 and December 31, 2024, respectively.

The Company has pledged loans totaling $918.1 million at June 30, 2025 and $933.9 million at December 31, 2024, for borrowing lines at the FHLB and FRB. Loans are pledged to increase and maintain 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 $2.6 million and $4.1 million at June 30, 2025 and December 31, 2024, respectively.

The gross balance of Main Street Lending Program (“MSLP”) loans participated and serviced for others, totaled $46.3 million at June 30, 2025 and $50.3 million at December 31, 2024, with $2.4 million in MSLP loans on the balance sheet and included in commercial and industrial loans at June 30, 2025 compared to $2.6 million at December 31, 2024. Servicing is retained on the gross balance.

The Company, through the Bank, at times purchases individual loans at fair value as of the acquisition date. The Company held purchased loans with remaining balances that totaled $4.5 million and $6.1 million as of June 30, 2025 and December 31, 2024, respectively. Unamortized premiums on these loans totaled $87,000 and $117,000 as of June 30, 2025 and December 31, 2024, respectively, and are amortized into interest income over the life of the loans. These loans are included in the applicable loan category depending upon the collateral and purpose of the individual loan.

The Company, through the Bank, has purchased participation loans with remaining balances totaling $27.2 million and $29.2 million as of June 30, 2025 and December 31, 2024, 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, through the Bank, purchased loans from CCBX partners, at par, through agreements with those CCBX partners, and those loans had a remaining balance of $157.0 million as of June 30, 2025 and $208.0 million as of December 31, 2024. As of June 30, 2025, $153.6 million is included in consumer and other loans and $3.4 million is included in commercial and industrial loans, compared to $202.7 million in consumer and other loans and $5.4 million in commercial and industrial loans as of December 31, 2024.

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 $26.1 million in unsecured CCBX partner loans. Loan types include revolving lines of credit, term loans, PPP 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. The Company issues letters of credit on behalf of its customers. 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 June 30, 2025, $199.7 million in outstanding CCBX capital call lines are included in commercial and industrial loans compared to $109.0 million at December 31, 2024. Capital call lines are provided to venture capital firms and investment funds. 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. These loans bear a lower rate of interest, but have less credit risk due to the way the loans are structured compared to other commercial loans.

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 primarily 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 June 30, 2025, $234.8 million in loans originated through CCBX partners are included in residential real estate loans, compared to $267.7 million at December 31, 2024. 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 non-owner 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 $380.8 million that are collateralized by owner-occupied real-estate and $553.9 million that are collateralized by non-owner-occupied real estate, as well as $363.7 million of multi-family residential loans and $12.4 million of farmland loans, as of June 30, 2025. 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 June 30, 2025, $1.22 billion in CCBX loans are included in consumer and other loans compared to $1.19 billion at December 31, 2024. Not included in this category are home equity lines of credit that are secured by residential real estate and are accessed by using a credit card of $234.8 million and $267.7 million as of June 30, 2025 and December 31, 2024, respectively. These credit card accessed home equity lines of credit are classified as residential real estate per regulatory guidelines.

The following chart breaks out our consumer loan portfolio by segment and type of loan as of June 30, 2025. The largest portion of our consumer portfolio is comprised of CCBX installment loans and credit card loans. These loans are further divided to show the total secured and unsecured amounts in each of these categories. The average overall outstanding consumer loan balance is small at $895.

The following chart breaks out our consumer loan portfolio by segment and type of loan as of December 31, 2024. The largest portion of our consumer portfolio is comprised of CCBX installment loans and credit card loans. These loans are further divided to show the total secured and unsecured amounts in each of these categories. The average overall outstanding consumer loan balance is small at $1,044.

Past Due and Nonaccrual Loans

The following table illustrates an age analysis of past due loans as of the dates indicated:

There were $32.6 million in CCBX loans past due 90 days or more and still accruing interest as of June 30, 2025, and $43.1 million as of December 31, 2024. This is attributed to loans originated through CCBX lending partners which continue to accrue interest up to 180 days past due. As of June 30, 2025 and December 31, 2024, $31.6 million and $41.8 million, respectively of loans past due 90 days or more and still accruing interest 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 typically continue to accrue interest until 120 and 180 days past due, respectively and an allowance is recorded through provision expense for these expected losses. Some CCBX partners have instituted a collection practice that places certain loans on nonaccrual status to improve collectibility. As of June 30, 2025, $20.1 million of these nonaccrual CCBX loans were less than 90 days past due, compared to $17.2 million as of December 31, 2024. 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 leastsix 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:

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 leastsix months in duration.

There was one modified loan for a community bank borrower experiencing financial difficulty in the three and six months ended June 30, 2025, and no community bank loans were modified in the three and six months ended June 30, 2024. The Company has no commitment to lend additional amounts to this borrower.

The following table presents the community bank loan that was both experiencing financial difficulty and was modified during the year by class and by type of modification for the periods indicated with the percentage of community bank loans that were modified to borrowers in financial distress as compared to the total of each class of community bank loans. Also presented is the financial effect of the loan modification to the borrower experiencing financial difficulty for the year ended as indicated.

.

The following table presents the CCBX loans at June 30, 2025 that were both experiencing financial difficulty and were modified during the twelve months prior to June 30, 2025 by class and by type of modification. The percentage of the loans that were modified to borrowers in financial distress as compared to the total CCBX loans of each class is also presented below.

The Company has committed to lend additional amounts totaling $44,000 to the borrowers included in the table above as of June 30, 2025.

The performance of loans modified is monitored to understand the effectiveness of the modification efforts. The following table presents the performance of such loans that have been modified in the last 12 months:

The following table presents the financial effect of the loan modifications presented above to borrowers experiencing financial difficulty for the preceding 12 months ended June 30, 2025:

The following table presents the total of loans that had a payment default during the preceding 12 months ended June 30, 2025 and which were modified for borrowers experiencing financial difficulty in the twelve months prior to that default.

Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is charged-off against the allowance for credit losses. Therefore, the loan balance is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.

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 typically 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 once they are 90 days past due. CCBX partners may place certain loans on nonaccrual status prior to achieving these past due timelines. 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.

The following tables show the risk category of community bank loans by year of origination for the periods indicated, based on the most recent analysis performed as of each period end:

The Company considers the performance of the CCBX loan portfolio and its impact on the allowance for credit losses. For CCBX loans, the Company also evaluates credit quality based on the aging status of the loan, which was previously presented, and by payment activity. The following tables present the loans in CCBX based on payment activity for the periods indicated:

Allowance for Credit Losses ("ACL")

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, reclassified negative deposit accounts and accrued interest receivable on CCBX loans. 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 its 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 5% of a $296.3 million loan portfolio that are without credit enhancement reimbursements. At June 30, 2025,5% of this portfolio represented $19.8 million in loans. The partner is responsible for reimbursing credit losses on approximately 95% of this portfolio and for fraud losses on 100% of this portfolio. The Company earns 100% of the interest income on the aforementioned $19.8 million of loans.

The following tables summarize the allocation of the ACL, as well as the activity in the ACL attributed to various segments in the loan portfolio, as of and for the three and six months ended June 30, 2025 and for the three and six months ended June 30, 2024:

There was a provision for unfunded commitments of $1.5 million and $2.1 million, respectively for the three and six months ended June 30, 2025 and a provision for unfunded commitments of $435,000 and $4.1 million, respectively for the three and six months ended June 30, 2024. There was a provision recapture for accrued interest receivable of $182,000 for the three months ended June 30, 2025 and a provision of $602,000 for the six months ended June 30, 2025 on CCBX loans, there wasno provision for accrued interest receivable for the three and six months ended June 30, 2024.

The following table presents the collateral dependent loans, which are individually evaluated to determine expected credit losses, and the related ACL allocated to these loans as of the dates indicated:

Note 5 -Deposits

The composition of consolidated deposits consisted of the following at the periods indicated:

The following table presents the maturity distribution of time deposits as of June 30, 2025:

Included in other deposits is $452.4 million in IntraFi network interest bearing demand and money market sweep accounts as of June 30, 2025, compared to $414.0 million at December 31, 2024, which provides our customers with fully insured deposits through a sweep and exchange of deposits with other financial institutions.

Note 6 -Leases

The Company has committed to rent premises and equipment used in business operations under non-cancelable operating and finance leases and determines if an arrangement meets the definition of a lease upon inception.

Operating and finance lease right-of-use (“ROU”) assets represent a right to use an underlying asset for the contractual lease term. Lease liabilities represent an obligation to make lease payments arising from the lease. A lease ROU asset and lease liability will be recognized for any new 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 and finance lease liabilities. The weighted average discount rate as of June 30, 2025 was 4.01% for operating leases and 4.75% for finance leases and is based off the discount rate at the time the lease is originated or renewed.

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.

Leases with terms of 12 months or less are not included in ROU assets and 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 June 30, 2025, lease expiration dates ranged from 8 months to 20 years, with additional renewal options on certain leases typically ranging from 12 months to 10 years. At June 30, 2025, 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 8.0 years. The weighted average remaining lease term for the Company's finance lease was 1.3 years.

Rental expense for operating leases is recognized on a straight-line basis over the lease term and amounted to $291,000 and $582,000, respectively for the three and six months ended June 30, 2025 and $297,000 and $596,000, respectively for the three and six months ended June 30, 2024. Variable lease components, such as inflation adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities.

Amortization expense for finance leases is recognized on a straight-line basis over the lease term and amounted to $8,000 and $17,000, respectively for the three and six months ended June 30, 2025. Interest on finance leases was $500 and $1,000, respectively for the three and six months ended June 30, 2025. This was a new lease in 2024, so there was $26,000 amortization or interest expense for the three and six months ended June 30, 2024.

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 June 30, 2025:

Note 7 -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. On May 28, 2025, the Company's shareholders approved the Second 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 andno further awards will be granted under these prior plans. Shares available to be granted under the 2018 plan were 686,741 at June 30, 2025.

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 wereno new stock options granted in the six months ended June 30, 2025 and 2024.

A summary of stock option activity under the 2018 Plan and 2006 Plan during the six months ended June 30, 2025:

The total intrinsic value (which is the amount by which the stock price at the date of exercise exceeds the exercise price) of options exercised during the three and six months ended June 30, 2025 was $2.7 million and $4.5 million, respectively. The total intrinsic value of options exercised during the three and six months ended June 30, 2024 was $720,000 and $2.1 million, respectively.

As of June 30, 2025, there was $366,000 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 2.6 years. Compensation expense recorded related to stock options was $93,000 and $147,000, respectively for the three and six months ended June 30, 2025 and $63,000 and $176,000, respectively for the three and six months ended June 30, 2024.

Restricted Stock Units

In the first two quarters of 2025, the Company granted 73,475 restricted stock units ("RSUs") under the 2018 Plan to employees, which vest ratably over various terms ranging from 4 years to 5 years. Additionally, the Company granted 41,185 performance-based restricted stock units ("PSUs") under the 2018 Plan that are eligible to vest over various terms ranging from 1.5 years to 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 June 30, 2025, there was $19.0 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 3.6 years. Compensation expense recorded related to RSUs was $1.7 million and $4.0 million, respectively for the three and six months ended June 30, 2025 and $895,000 and $1.8 million, respectively for the three and six months ended June 30, 2024.

A summary of the Company’s nonvested RSUs at June 30, 2025 and changes during the six month period is presented below:

Restricted Stock Awards

Employees

There wereno new restricted stock awards granted in the six months ended June 30, 2025. 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 June 30, 2025, there was $23,000 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 2.6 years.

Note 8 -Fair Value Measurements

The following tables present estimated fair values of the Company’s financial instruments as of the period indicated, whether or not recognized or recorded in the consolidated balance sheets at the period indicated:

The Company measures and discloses certain assets and liabilities at fair value. 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:

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 June 30, 2025 and December 31, 2024. 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:

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 a 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 June 30, 2025, with adjustments recorded during the periods presented for those securities with observable price changes, if applicable. These equity securities are included in other investments on the balance sheet.

•The Company had a $1.8 million and $2.2 million equity interest in a specialized bank technology company as of the quarters ended June 30, 2025, and June 30, 2024, respectively. There was a $443,000 write-down during the quarter ended June 30, 2025 due to a re-valuation, which is done at least quarterly. Management doesn’t believe the write-down is indicative of longer-term concerns at this time.

•The Company had a $350,000 equity interest in a technology company as of the quarters ended June 30, 2025, and June 30, 2024.

•The Company had a $47,000 and $50,000 equity interest in a technology company as of the quarters ended June 30, 2025, and June 30, 2024, respectively.

The following table provides a description of the valuation technique, unobservable inputs, and qualitative information about the unobservable inputs for the Company’s assets and liabilities classified as Level 3 and measured at fair value on a nonrecurring basis at the date indicated:

Note 9 -Earnings Per Common Share

The following is a computation of basic and diluted earnings per common share at the periods indicated:

Under the two-class method, earnings available to common shareholders for the period are allocated between common shareholders and participating securities according to dividends declared (or accumulated) and participation rights in undistributed earnings, however the difference in the two-class method was not significant.

Note 10 –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 (“CODM”) 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 classifications within accounting and reporting systems, 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 Executive Leadership Team, which includes the CEO, Presidents, CFO and other key executive members, which the Company has designated as the CODMs, evaluates the financial performance of the Company’s segments by evaluating interest income and expense, noninterest income and significant expenses. The community bank segment includes all community banking activities. 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 andone in Island County). The CCBX segment provides BaaS that allows digital financial service providers, companies and brands to offer their customers banking services. The CCBX segment has 29 partners as of June 30, 2025. 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. Additionally, certain indirect expenses are allocated to each segment utilizing various metrics, such as number of employees, utilization of space, and allocations based on loan and deposit balances. We have implemented a transfer pricing process that credits or charges the community bank and CCBX segments with intrabank interest income or expense for the difference in average loans and average deposits, with the treasury & administration segment as the offset for those entries.

Summarized financial information concerning the Company's reportable segments and the reconciliation to the consolidated financial results is shown in the following tables for the periods indicated:
