(the “Company”) is a Florida corporation incorporated in 1985, which has operated since January 1987. The Company is a bank holding company registered under the Bank Holding Company Act of 1956 (“BHC Act”), as a result of its 100% ownership of Amerant Bank, N.A. (the “Bank”). The Company’s principal office is in the City of Coral Gables, Florida. The Bank is a member of the Federal Deposit Insurance Corporation (“FDIC”), the Federal Reserve Bank of Atlanta (“Federal Reserve”) and the Federal Home Loan Bank of Atlanta (“FHLB”). The Bank is a national bank subject to regulation and regular examinations by the Office of the Comptroller of the Currency (“OCC”).The Bank has three operating subsidiaries: Amerant Investments, Inc., a securities broker-dealer (“Amerant Investments”), Amerant Mortgage, LLC (“Amerant Mortgage”), a mortgage lending company domiciled in Florida (“Amerant Mortgage”) and Elant Bank & Trust Ltd., a Grand-Cayman based trust company (the “Cayman Bank”). Sale of Houston Banking Operations On April 16, 2024, the Bank entered into a Purchase and Assumption Agreement (the “Purchase Agreement”) with MidFirst Bank (“MidFirst”) pursuant to which MidFirst will purchase certain assets and assume certain liabilities (the “Houston Sale Transaction”) of the banking operations and six branches in the Houston, Texas metropolitan statistical area (collectively, the “Branches”). Pursuant to the terms of the Purchase Agreement, MidFirst has agreed to assume certain deposit liabilities and to acquire certain loans, as well as cash, real property, personal property and other fixed assets associated with the Branches, as well as 45 team members. On July 30, 2024, regulatory approval for the Houston Sale Transaction was received. The Houston Sale Transaction is expected to close on November 2024, subject to the satisfaction of customary closing conditions. The purchase price for the purchased assets will be computed as the sum of: (a) $13.0 million (the “Deposit Premium”), provided that, if the balance of non-interest checking deposits included in deposits or the total balance of deposits (excluding insured cash sweep deposits) decrease by more than 15% between March 13, 2024 and the closing date, then the Deposit Premium shall be equal to the sum of (i) 9.50% of the average daily balance of non-interest checking deposits included in deposits, (ii) 1.85% of the average daily balance of deposits other than non-interest checking deposits, insured cash sweep deposits and time deposits included in deposits, (iii) 0.25% of the average daily balance of insured cash sweep deposits included in Deposits, and (iv) 0.50% of the average daily balance of time deposits included in deposits, with the average daily balance in each case being for the 30-day period ending on the fifth business day prior to closing, provided further, that the Deposit Premium shall in no event be lower than $9.25 million, (b) the aggregate amount of cash on hand as of the closing date, (c) the aggregate net book value of all assets being assumed (excluding cash on hand, real property and accrued interest with respect to the loans to be acquired), (d) the appraised value of the real property to be acquired, and (e) accrued interest with respect to the loans to be acquired. The purchase price is subject to a customary post-closing adjustment based on the delivery within 30 calendar days following the closing date of a final closing statement setting forth the purchase price and any necessary adjustment payment amount. The Bank and MidFirst made customary representations, warranties, and covenants in the Purchase Agreement. The Bank and MidFirst also agreed to indemnify each other (subject to customary limitations) with respect to the Transaction, including for breaches of representations and warranties, breaches of covenants, liabilities not retained or assumed, and conduct of the business of the Branches and operation and use of the purchased assets during certain time periods.

Accordingly, they do not include all of the information and footnotes required for a fair statement of financial position, results of operations and cash flows in conformity with GAAP. These unaudited interim consolidated financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the results for the interim periods presented. These adjustments are of a normal, recurring nature. Interim period operating results may not be indicative of the operating results for a full year or any other period. These unaudited interim consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements as of December 31, 2023 and 2022 and for each of the three years in the period ended December 31, 2023 and the accompanying footnote disclosures for the Company, which are included in the 2023 Form 10-K. For a complete summary of our significant accounting policies, see Note 1 to the Company’s audited consolidated financial statements in the 2023 Form 10-K. 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 periods. Significant estimates made by management include: (i) the determination of the allowance for credit losses; (ii) the fair values of loans, securities and derivative contracts; (iii) the cash surrender value of bank owned life insurance; and (iv) the determination of whether the amount of deferred tax assets will more likely than not be realized. Management believes that these estimates are appropriate. Actual results could differ from these estimates. c) Recently Issued Accounting Pronouncements For a description of recently issued accounting pronouncements, see Note 1 to the Company’s audited consolidated financial statements in the 2023 Form 10-K. d) Subsequent Events The effects of other significant subsequent events, if any, have been recognized or disclosed in these unaudited interim consolidated financial statements.

The Company does not intend to sell these debt securities and it is more likely than not that it will not be required to sell the securities before their anticipated recovery. The Company evaluates these securities for credit losses by reviewing current market conditions, the extent and nature of changes in fair value, credit ratings, default and delinquency rates and current analysts’ evaluations. The Company believes the decline in fair value on these debt securities is attributable to changes in interest rates and investment securities markets, generally, and not credit quality. As a result, the Company did not record an Allowance for Credit Losses, or ACL, on these securities as of June 30, 2024 and December 31, 2023. Corporate Debt Securities Investments in corporate debt securities available for sale in an unrealized loss position as of June 30, 2024 include: (i) securities considered “investment-grade-quality,” primarily issued by financial institutions, with a fair value of $225.3 million ($252.4 million at December 31, 2023) and total unrealized losses of $19.1 million at that date ($23.8 million at December 31, 2023), and (ii) securities considered “non-investment-grade-quality,” primarily from companies in the technology industry, with a fair value of $8.3 million ($8.4 million at December 31, 2023) and total unrealized losses of $0.7 million at that date ($0.6 million at December 31, 2023). As of June 30, 2024 and December 31, 2023, our corporate debt securities available for sale issued by financial institutions were primarily “investment-grade-quality”, and had a fair value of $188.7 million and $186.9 million, respectively, and net unrealized losses of $13.3 million and $18.2 million, respectively. The Company does not intend to sell its investments in corporate debt securities available for sale and it is more likely than not that it will not be required to sell these investments before their anticipated recovery. The Company evaluates corporate debt securities for credit losses by reviewing various qualitative and quantitative factors such as current market conditions, the extent and nature of changes in fair value, credit ratings, default and delinquency rates, and current analysts’ evaluations. The Company believes the decline in fair value on these debt securities is attributable to changes in interest rates and investment securities markets, generally, and not credit quality. As a result, the Company did not record an ACL on these securities as of June 30, 2024 and December 31, 2023. On March 12, 2023, Signature Bank, N.A. (“Signature”) was closed by the New York State Department of Financial Services, which appointed the FDIC as receiver. The FDIC, as receiver, announced that shareholders and certain unsecured debt holders would not be protected. On March 27, 2023, the Bank sold in an open market transaction one corporate debt security held for sale issued by Signature (the “Signature Bond”) with a fair value of $9.1 million and unrealized loss of $0.9 million, and realized a pretax loss on sale of approximately $9.5 million, which is recorded in the consolidated statement of comprehensive income for the six months ended June 30, 2023. In May 2023, the Company sold a portion of its investment in a corporate debt security held for sale issued by a financial institution, to reduce single point exposure. The Company had proceeds of $0.8 million and realized a pre-tax loss of $1.2 million in connection with this transaction. This loss was recorded in the consolidated statement of comprehensive (loss) income for the three and six months ended June 30, 2023.

The Company considers that all debt securities held to maturity issued or sponsored by the U.S. government are considered to be risk-free as they have the backing of the government. The Company believes there are no current expected credit losses on these securities and, therefore, did not record an ACL on any of its debt securities held to maturity as of June 30, 2024 and December 31, 2023.

Allowance for Credit Losses	Allowance for Credit Losses The analyses by loan segment of the changes in the Allowance for Credit Losses, or ACL, for loans for the three and six month periods ended June 30, 2024 and 2023 is summarized in the following tables: Three Months Ended June 30, 2024 (in thousands) Real Estate Commercial Financial Consumer Total Balance at beginning of the period $ 22,322 $ 47,547 $ — $ 26,181 $ 96,050 (Reversal of) provision for credit losses - loans (3,269) 17,648 — 3,271 17,650 Loans charged-off — (13,452) — (6,762) (20,214) Recoveries 11 400 — 503 914 Balance at end of the period $ 19,064 $ 52,143 $ — $ 23,193 $ 94,400 Six Months Ended June 30, 2024 (in thousands) Real Estate Commercial Financial Consumer Total Balance at beginning of the period $ 25,876 $ 41,809 $ — $ 27,819 $ 95,504 (Reversal of) provision for credit losses - loans (6,257) 25,231 — 11,076 30,050 Loans charged-off (591) (15,876) — (16,949) (33,416) Recoveries 36 979 — 1,247 2,262 Balance at end of the period $ 19,064 $ 52,143 $ — $ 23,193 $ 94,400 Three Months Ended June 30, 2023 (in thousands) Real Estate Commercial Financial Consumer Total Balance at beginning of the period $ 23,195 $ 30,647 $ — $ 30,519 $ 84,361 Provision for credit losses - loans 18,903 6,386 — 3,788 29,077 Loans charged-off — (1,452) — (7,633) (9,085) Recoveries 140 1,045 — 418 1,603 Balance at end of the period $ 42,238 $ 36,626 $ — $ 27,092 $ 105,956 Six Months Ended June 30, 2023 (in thousands) Real Estate Commercial Financial Consumer Total Balance at beginning of the period $ 25,237 $ 25,888 $ — $ 32,375 $ 83,500 Provision for credit losses - loans 16,722 15,787 — 8,268 40,777 Loans charged-off — (9,427) — (13,987) (23,414) Recoveries 279 4,378 — 436 5,093 Balance at end of the period $ 42,238 $ 36,626 $ — $ 27,092 $ 105,956 The ACL was determined utilizing a reasonable and supportable forecast period. The ACL was determined using a weighted-average of various economic scenarios provided by a third-party and incorporated qualitative components. There have not been material changes in our policies and methodology to estimate the ACL in the six months ended June 30, 2024. The ACL decreased by $1.1 million, or 1.2% at June 30, 2024, compared to December 31, 2023. The ACL as a percentage of total loans held for investment was 1.41% at June 30, 2024 compared to 1.39% at December 31, 2023. The provision for credit losses on loans in the three and six month periods ended June 30, 2024 was partially offset by net charge-offs. In the second quarter of 2024, the provision for credit losses on loans included $12.8 million to cover for charge-offs, $12.7 million in new specific reserves for non-performing loans, and $1.8 million due to loan composition and volume changes. These provision requirements were partially offset by a release of $5.2 million due to general credit quality factors, as well as, macroeconomic factor updates and a $4.4 million release due to the Houston loan portfolio classification as held-for-sale. In the first half of 2024, the provision for credit losses on loans included $24.5 million to cover charge-offs, $12.7 million in new specific reserves for non-performing loans and $4.2 million due to loan composition and volume changes. These provision requirements were partially offset by a release of $6.8 million due to credit quality and macroeconomic factor updates and a $4.4 million release due to the Houston loan portfolio classification as held-for-sale. The following is a summary of net proceeds from sales of loans held for investment by portfolio segment: Three Months Ended June 30, Real Estate Commercial Financial Consumer Total 2024 $ — $ 4,681 $ — $ — $ 4,681 2023 $ 3,575 $ 887 $ — $ — $ 4,462 Six Months Ended June 30, Real Estate Commercial Financial Consumer Total 2024 $ 1,768 $ 65,628 $ — $ — $ 67,396 2023 $ 13,575 $ 887 $ — $ — $ 14,462 Loan Modifications to Borrowers Experiencing Financial Difficulty The Company modifies loans related to borrowers experiencing financial difficulties by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted. The Company had no new loan modifications to borrowers experiencing financial difficulty during the three and six month periods ended June 30, 2024 and 2023. There were no loans that defaulted in the six months ended June 30, 2024 and 2023 and had been modified within 12 months preceding the payment default related to these modifications. Credit Risk Quality The sufficiency of the ACL is reviewed at least quarterly by the Chief Risk Officer and the Chief Financial Officer. The Board of Directors considers the ACL as part of its review of the Company’s consolidated financial statements. As of June 30, 2024 and December 31, 2023, the Company believes the ACL to be sufficient to absorb expected credit losses in the loans portfolio in accordance with GAAP. Loans may be classified but not considered collateral dependent due to one of the following reasons: (1) the Company has established minimum dollar amount thresholds for individual assessment of expected credit losses, which results in loans under those thresholds being excluded from individual assessment of expected credit losses; and (2) classified loans may be considered in the assessment because the Company expects to collect all amounts due. As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related primarily to (i) the risk rating of loans, (ii) the loan payment status, (iii) net charge-offs, (iv) nonperforming loans and (v) the general economic conditions in the main geographies where the Company’s borrowers conduct their businesses. The Company considers the views of its regulators as to loan classification and in the process of estimating expected credit losses. The Company utilizes an internal risk rating system to identify the risk characteristics of each of its loans, or group of homogeneous loans such as consumer loans. Internal risk ratings are updated on a continuous basis on a scale from 1 (worst credit quality) to 10 (best credit quality). Loans are then grouped in five master risk categories for purposes of monitoring rising levels of potential loss risks and to enable the activation of collection or recovery processes as defined in the Company’s Credit Risk Policy. Internal risk ratings are considered the most meaningful indicator of credit quality for commercial loans. Generally, internal risk ratings for commercial real estate loans and commercial loans with balances over $3 million are updated at least annually and more frequently if circumstances indicate that a change in risk rating may be warranted. For consumer loans, single-family residential loans and smaller commercial loans under $3 million, risk ratings are updated based on the loans past due status. The following is a summary of the master risk categories and their associated loan risk ratings, as well as a description of the general characteristics of the master risk category: Loan Risk Rating Master risk category Nonclassified 4 to 10 Classified 1 to 3 Substandard 3 Doubtful 2 Loss 1 N onclassified This category includes loans considered as Pass (5-10) and Special Mention (4). A loan classified as Pass is considered of sufficient quality to preclude a lower adverse rating. These loans are generally well protected by the current net worth and paying capacity of the borrower or by the value of any collateral received. Special Mention loans are defined as having potential weaknesses that deserve management’s close attention which, if left uncorrected, could potentially result in further credit deterioration. Special Mention loans may include loans originated with certain credit weaknesses or that developed those weaknesses since their origination. Classified This classification indicates the presence of credit weaknesses which could make loan repayment unlikely, such as partial or total late payments and other contractual defaults. Substandard A loan classified substandard is inadequately protected by the sound worth and paying capacity of the borrower or the collateral pledged. They are characterized by the distinct possibility that the Company will sustain some loss if the credit weaknesses are not corrected. Loss potential, while existing in the aggregate amount of substandard loans, does not have to exist in individual assets. Doubtful These loans have all the weaknesses inherent in a loan classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. These are poor quality loans in which neither the collateral, if any, nor the financial condition of the borrower presently ensure collection in full in a reasonable period of time. As a result, the possibility of loss is extremely high. Loss Loans classified as loss are considered uncollectible and of such little value that the continuance as bankable assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but not to the point where a write-off should be deferred even though partial recoveries may occur in the future. This classification is based upon current facts, not probabilities. As a result, loans in this category should be promptly charged off in the period in which they are determined to be uncollectible.

collateral-dependent when the repayment of the loan is expected to be provided by the sale or operation of the underlying collateral. The Company performs an individual evaluation as part of the process of calculating the allowance for credit losses related to these loans. The following tables present the amortized cost basis of collateral dependent loans related to borrowers experiencing financial difficulty by type of collateral as of June 30, 2024 and December 31, 2023: As of June 30, 2024 Collateral Type (in thousands) Commercial Real Estate Residential Real Estate Other Total Specific Reserves Real estate loans Single-family residential (1) $ — $ 738 $ — $ 738 $ — Owner occupied (2) 26,292 — — 26,292 — 26,292 738 — 27,030 — Commercial loans 3,344 — 68,162 71,506 17,330 Consumer loans and overdrafts — — — — — Total $ 29,636 $ 738 $ 68,162 $ 98,536 $ 17,330 _________________ (1) Weighted-average loan-to-value was approximately 61.8% at June 30, 2024.

(2) Weighted-average loan-to-value was approximately 73.0% at December 31, 2023. Collateral dependent loans are evaluated on an individual basis for purposes of determining expected credit losses. For collateral-dependent loans where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the loan as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the loan exceeds the present value of expected cash flows from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the loan exceeds the fair value of the underlying collateral less estimated costs to sell. The ACL may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the loan.

These interest rate swaps are designed as cash flow hedges to manage the exposure that arises from differences in the amount of the Company’s known or expected cash receipts and the known or expected cash payments on designated debt instruments. These interest rate swap contracts involve the Company’s payment of fixed-rate amounts in exchange for the Company receiving variable-rate payments over the life of the contracts without exchange of the underlying notional amount. At June 30, 2024 and December 31, 2023, the Company had five interest rate swap contracts with notional amounts totaling $64.2 million maturing in the third and fourth quarters of 2025. These contracts were designated as cash flow hedges to manage the exposure of variable rate interest payments on all of the Company’s outstanding variable-rate junior subordinated debentures with principal amounts at June 30, 2024 and December 31, 2023 totaling $64.2 million. The Company expects these interest rate swaps to be highly effective in offsetting the effects of changes in interest rates on cash flows associated with the Company’s variable-rate junior subordinated debentures. The Company recognized unrealized gains of $0.2 million and $0.1 million in the three months ended June 30, 2024 and 2023, respectively, and unrealized gains of $0.4 million and $0.2 million in the six months ended June 30, 2024 and 2023, respectively, related to these interest rate swap contracts. In connection with these interest rate swap contracts, which were included as part of interest expense on junior subordinated debentures in the Company’s consolidated statement of operations and comprehensive income. As of June 30, 2024, the estimated net unrealized gains in accumulated other comprehensive income expected to be reclassified into expense in the next twelve months amounted to $0.7 million. In 2019, the Company terminated 16 interest rate swaps that had been designated as cash flow hedges of variable rate interest payments on the outstanding and expected rollover of variable-rate advances from the FHLB. The Company is recognizing the contracts’ cumulative net unrealized gains of $8.9 million in earnings over the remaining original life of the terminated interest rate swaps ranging between one month and seven years. The Company recognizes a reduction of interest expense on FHLB advances as a result of this amortization. Interest Rate Swaps On Loans In the second quarter of 2023, the Company entered into an interest rate swap contract with a notional amount of $50.0 million, and maturity in the second quarter of 2025. The Company designated this interest rate swap as a cash flow hedge to manage interest rate risk exposure on variable rate interest receipts on the first $50 million principal balance of a pool of loans. This interest rate swap contract involves the Company’s payment of variable-rate amounts in exchange for the Company receiving fixed-rate payments over the life of the contract without exchange of the underlying notional amount. Unrealized losses on these instruments are included as part of interest income on loans in the Company’s consolidated statement of operations and comprehensive income. Derivatives Not Designated as Hedging Instruments a) Customer related positions The Company offers certain derivatives products, including interest rate swaps and caps, directly to qualified commercial banking customers to facilitate their risk management strategies. The Company partially offsets its exposure to interest rate swaps and caps by entering similar derivative contracts with various third-party brokers. Interest Rate Swaps Interest rate swap contracts involve the Company’s payment of variable-rate amounts to customers in exchange for the Company receiving fixed-rate payments from customers over the life of the contracts without exchange of the underlying notional amount. The Company enters into swap participation agreements with other financial institutions to manage the credit risk exposure on certain interest rate swaps with customers. Under these agreements, the Company, as the beneficiary or guarantor, will receive or make payments from/to the counterparty if the borrower defaults on the related interest rate swap contract. The notional amount of these agreements is based on the Company’s pro-rata share of the related interest rate swap contracts. Interest Rate Caps Interest rate cap contracts involve the Company making payments if an interest rate exceeds the agreed strike price. In April 2022, the Company entered into four interest rate cap contracts with various third-party brokers with total notional amounts of $140.0 million. These interest rate caps initially served to partially offset changes in the estimated fair value of interest rate cap contracts with customers. At December 31, 2023, there was one interest rate cap contract with a notional amount of $35.0 million in connection with this transaction. At June 30, 2024, there were no interest rate cap contracts in connection with this transaction. b) Mortgage Derivatives The Company enters into interest rate lock commitments and forward sale contracts to manage the risk exposure in the mortgage banking area. Interest rate lock commitments guarantee the funding of residential mortgage loans originated for sale, at specified interest rates and times in the future. Forward sale contracts consist of commitments to deliver mortgage loans, originated and/or purchased, in the secondary market at a future date. The change in the fair value of these instruments was an unrealized gain of $0.2 million and an unrealized loss of $0.6 million in the three months ended June 30, 2024 and 2023, respectively, and an unrealized gain of $0.5 million and $36 thousand in the six months ended June 30, 2024 and 2023, respectively. These amounts were recorded as part of other noninterest income in the consolidated statements of operations and comprehensive income. Credit Risk-Related Contingent Features Some agreements may require the Company to pledge securities as collateral when the valuation of the interest rate swap derivative contracts fall below a certain amount. There were no securities pledged as collateral for interest rate swaps in a liability position at June 30, 2024 and December 31, 2023. Additionally, most of our derivative arrangements with counterparties require the posting of collateral upon meeting certain net exposure thresholds. As of June 30, 2024 and December 31, 2023, the Company had cash held as collateral of $31.5 million and $25.0 million, respectively. See

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company uses an estimated annual effective tax rate method in computing its interim tax provision. This effective tax rate is based on forecasted annual consolidated pre-tax income, permanent tax differences and statutory tax rates. Under this method, the tax effect of certain items that do not meet the definition of ordinary income or expense are computed and recognized as discrete items when they occur. The effective combined federal and state tax rates for the six months ended June 30, 2024 and 2023 were 21.50% and 21.00%, respectively. Effective tax rates differ from the statutory rates mainly due to the impact of forecasted permanent non-taxable interest and other income, forecasted permanent non-deductible expenses, and the effect of corporate state taxes.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	Contingencies From time to time the Company and its subsidiaries may be exposed to loss contingencies. In the ordinary course of business, those contingencies may include, known but unasserted claims, and legal/regulatory inquiries or examinations.

The following table presents the significant unobservable inputs (Level 3) used in the valuation of assets measured at fair value on a nonrecurring basis. Financial Instrument Unobservable Inputs Valuation Methods Discount Range Typical Discount Collateral dependent loans Discount to fair value Appraisal value, as adjusted 0-30% 6-7% Inventory 0-100% 30-50% Accounts receivables 0-100% 20-30% Equipment 0-100% 20-30% Other Real Estate Owned Discount to fair value Appraisal value, as adjusted N/A 6-7% There were no other significant assets or liabilities measured at fair value on a nonrecurring basis at June 30, 2024 and December 31, 2023. Loans Held for Sale, at Lower of Cost or Fair Value For loans held for sale that are carried at the lower of cost or fair value, the fair value is generally based on quoted market prices of similar loans less estimated cost to sell and is considered to be Level 3. Collateral Dependent Loans Measured For Expected Credit Losses The carrying amount of collateral dependent loans is typically based on the fair value of the underlying collateral. The Company primarily uses third party appraisals to assist in measuring expected credit losses on collateral dependent loans. The Company also uses third party appraisal reviewers for loans with an outstanding balance of $1 million and above. These appraisals generally use the market or income approach valuation technique and use market observable data to formulate an opinion of the fair value of the loan’s collateral. However, the appraiser uses professional judgment in determining the fair value of the collateral or properties and may also adjust these values for changes in market conditions subsequent to the appraisal date. When current appraisals are not available for certain loans, the Company uses judgment on market conditions to adjust the most current appraisal. The sales prices may reflect prices of sales contracts not closed and the amount of time required to sell out the real estate project may be derived from current appraisals of similar projects. As a consequence, the fair value of the collateral is considered a Level 3 valuation. OREO The Company values OREO at the lower of cost or fair value of the property, less cost to sell. The fair value of the property is generally based upon recent appraisal values of the property, less cost to sell. The Company primarily uses third party appraisals to assist in measuring the valuation of OREO. Period revaluations are classified as level 3 as the assumptions used may not be observable. The Company had other repossessed assets with a carrying value of $6.4 million, which were sold in the three and six month periods ended June 30, 2023. The Company recognized a loss on sale of $2.6 million which is included in the result of operations for those periods. Fair Value of Financial Instruments The estimated fair value of financial instruments where fair value differs from carrying value are as follows: June 30, 2024 December 31, 2023 (in thousands) Carrying Estimated Carrying Estimated Financial assets: Debt securities held to maturity $ 219,613 $ 192,403 $ 226,645 $ 204,945 Loans 3,225,040 3,074,592 3,514,114 3,321,308 Financial liabilities: Time deposits 1,610,616 1,606,643 1,577,579 1,575,569 Advances from the FHLB 765,000 762,588 645,000 644,572 Senior notes 59,685 58,718 59,526 58,337 Subordinated notes 29,539 28,481 29,454 28,481 Junior subordinated debentures 64,178 63,177 64,178 63,285

In the three and six month periods ended June 30, 2024 and 2023, potential dilutive instruments were included in the diluted earnings per share computation because, when the unamortized deferred compensation cost related to these shares was divided by the average market price per share in those periods, fewer shares would have been purchased than restricted shares assumed issued. Therefore, in those periods, such awards resulted in higher diluted weighted average shares outstanding than basic weighted average shares outstanding, and had a dilutive effect on per share earnings.
