Basis of Presentation
Basis of Presentation	Note 1: Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Merchants Bancorp, a registered bank holding company (the “Company”) and its wholly owned subsidiaries, Merchants Bank of Indiana (“Merchants Bank”) and Farmers-Merchants Bank of Illinois (“FMBI”). Merchants Bank’s primary operating subsidiaries include Merchants Capital Corp. (‘MCC”) and Merchants Capital Servicing, LLC (“MCS”). All direct and indirectly owned subsidiaries owned by Merchants Bancorp are collectively referred to as the “Company”. The accompanying unaudited condensed consolidated balance sheet of the Company as of December 31, 2020, which has been derived from audited financial statements, and unaudited condensed consolidated financial statements of the Company as of June 30, 2021 and for the three and six months ended June 30, 2021 and 2020, were prepared in accordance with the instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include information or footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America. Accordingly, these condensed financial statements should be read in conjunction with the audited financial statements and notes thereto of the Company as of and for the year ended December 31, 2020 in its Annual Report on Form 10-K. Reference is made to the accounting policies of the Company described in the Notes to the Financial Statements contained in the Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) which are necessary for a fair presentation of the unaudited financial statements have been included to present fairly the financial position as of June 30, 2021 Principles of Consolidation The unaudited condensed consolidated financial statements as of and for the period ended June 30, 2021 and 2020 include results from the Company, and its wholly owned subsidiaries, Merchants Bank, and FMBI. Also included are Merchants Bank’s primary operating subsidiaries, MCC and MCS, as well as all 100% directly and indirectly owned subsidiaries owned by Merchants Bancorp. Additionally, the unaudited condensed consolidated financial statements include consolidated results from certain entities primarily involved in single-family debt financing until January 30, 2021, while the Company was deemed to be a primary beneficiary. A primary beneficiary is defined as, the party that has both the power to direct the activities that most significantly impact the entity, and an interest that could be significant to the entity. To determine if an interest could be significant to the entity, both qualitative and quantitative factors regarding the nature, size and form of our involvement with the entity are evaluated. All significant intercompany accounts and transactions have been eliminated in consolidation. On February 1, 2021, the Company’s debt fund entities were restructured in such a way that its ownership and participation was significantly reduced with the inclusion of additional, unrelated investors and the Company was no longer classified as a primary beneficiary. Accordingly, results from these entities were no longer consolidated after this date, in accordance with the consolidation guidelines of the Accounting Standards Update of Topic 810. Following the deconsolidation, the carrying value of assets and liabilities of these entities were removed from the consolidated balance sheet, and the continuing investments were recorded at fair value at the date of deconsolidation. The total amount deconsolidated from the balance sheet included net assets of approximately $10 million, consisting primarily of $66.6 million in loans receivable, and $52.7 million in borrowings with Merchants Bank that was previously eliminated in consolidation. The fair value of its continuing investments was approximately $10 million and has been reported in Other Assets after deconsolidation. The estimated fair value was determined based on third-party evaluations of similar assets in the underlying business. The difference between the fair value of these deconsolidated entities and their carrying value was deemed to be immaterial, resulting in no gain or loss on deconsolidation. The maximum loss exposure that would be absorbed by the Company in the event that these unconsolidated investments were deemed worthless is approximately $10.0 million at June 30, 2021. These continuing investments after deconsolidation are classified as variable interest entities, will not be consolidated, and are accounted for under the equity method of accounting. The Company will analyze whether its entities are the primary beneficiary on an ongoing basis. Changes in facts and circumstances occurring since the previous primary beneficiary determination will be considered as part of this ongoing assessment. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, loan servicing rights and fair values of financial instruments. The uncertainties related to the COVID-19 pandemic could cause significant changes to these estimates compared to what was known at the time these financial statements were prepared. Reclassifications ​ Certain reclassifications may have been made to the 2020 financial statements to conform to the financial statement presentation as of and for the three and six months ended June 30, 2021. These reclassifications had no effect on net income.

Loans and Allowance for Loan Losses
Loans and Allowance for Loan Losses	Note 4: Loans and Allowance for Loan Losses Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at their outstanding principal balances adjusted for unearned income, charge-offs, the allowance for loan losses, any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. For loans at amortized cost, interest income is accrued based on the unpaid principal balance. The accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Past-due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest collected on these loans is applied to the principal balance until the loan can be returned to an accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. For all loan portfolio segments, the Company promptly charges off loans, or portions thereof, when available information confirms that specific loans are uncollectable based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For impaired loans that are considered to be solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral. When cash payments for accrued interest are received on impaired loans in each loan class, the Company records the payment as interest income unless collection of the remaining recorded principal amount is doubtful, at which time payments are used to reduce the principal balance of the loan. Troubled debt restructured loans recognize interest income on an accrual basis at the renegotiated rate if the loan is in compliance with the modified terms. The Company offers warehouse loans or credit to fund mortgage loans held for sale from closing until sale to an investor. Under a warehousing arrangement the Company funds a mortgage loan as secured financing. The warehousing arrangement is secured by the underlying mortgages and a combination of deposits, personal guarantees and advance rates. The Company typically holds the collateral until it is sent under a bailee arrangement instructing the investor to send proceeds to the Company. Typical investors are large financial institutions or government agencies. Interest earned from the time of funding to the time of sale is recognized as interest income as accrued. Fees earned agreements are recognized when collected as noninterest income. Loan Sale and Freddie Mac Q Series Securitization On May 7, 2021, the Company entered into an arrangement through a third-party trust and Freddie Mac, by which a $262.0 million portfolio of multi-family loans were sold to the trust and ultimately securitized through Freddie Mac and sold to investors. The Company purchased two of the securities for a total of $28.7 million. The transfer of these loans was accounted for as a sale for financial reporting purposes, in accordance with ASC 860, and a $676,000 net loss on sale was recognized, which included the impact of establishing a risk share allowance and mortgage servicing rights associated with this transaction. Beyond holding the two securities, the Company’s ongoing involvement in this transaction is limited to customary obligations of loan sales, including any material breach in representation. In connection with the securitization and purchase of one of the securities, Merchants maintains a first loss position in the underlying loan portfolio not to exceed 10% of the unpaid principal amount of the loans comprising the securitization pool at settlement, or approximately $26.2 million. Therefore, a reserve of $1.4 million for estimated losses was established with respect to the first loss obligation at May 7, 2021, which is included in other liabilities on the consolidated balance sheets. These estimated losses are consistent with the amount in allowance for loan losses that was released when the loans were sold. If the Company sells one of the securities, this first loss obligation would be eliminated. As part of the securitization transaction, Merchants released all mortgage servicing obligations and rights to Freddie Mac who was designated as the Master Servicer. As Master Servicer, Freddie Mac appointed the Company with sub-servicing obligations, which include obligations to collect and remit payments of principal and interest, manage payments of taxes and insurance, and otherwise administer the underlying loans. Accordingly, the company recognized a Loan Portfolio Summary ‌ Loans receivable at June 30, 2021 and December 31, 2020 include: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ December 31, ​ 2021 2020 ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ Mortgage warehouse lines of credit ​ $ 1,177,940 ​ $ 1,605,745 Residential real estate ​ 806,325 ​ 678,848 Multi-family and healthcare financing ​ 2,970,770 ​ 2,749,020 Commercial and commercial real estate ​ 409,710 ​ 387,294 Agricultural production and real estate ​ 92,786 ​ 101,268 Consumer and margin loans ​ 15,392 ​ 13,251 ​ ​ 5,472,923 ​ 5,535,426 Less ​ ​ Allowance for loan losses ​ 28,696 ​ 27,500 ​ ​ ​ ​ ​ ​ ​ Loans Receivable ​ $ 5,444,227 ​ $ 5,507,926 ​ In response to the COVID-19 global pandemic, the Coronavirus Aid, Relief and Economic Security Act (“CARES Act”) established the Paycheck Protection Program (“PPP”) to provide loans for eligible business/not-for-profits. These loans qualify for forgiveness when used for qualifying expenses during the appropriate period. Loans funded through the PPP are fully guaranteed by the U.S. government. Commercial and commercial real estate loans at June 30, 2021 and December 31, 2020 include PPP loans with principal balances of $53.6 million and $60.2 million, respectively, that had not yet been forgiven. Risk characteristics applicable to each segment of the loan portfolio are described as follows. Mortgage Warehouse Lines of Credit (MTG WHLOC): Under its warehouse program, the Company provides warehouse financing arrangements to approved mortgage companies for the origination and sale of residential mortgage loans and to a lesser extent multi-family loans. Agency eligible, governmental and jumbo residential mortgage loans that are secured by mortgages placed on existing one-to-four family dwellings may be originated or purchased and placed on each mortgage warehouse line. As a secured repurchase agreement, collateral pledged to the Company secures each individual mortgage until the lender sells the loan in the secondary market. A traditional secured warehouse line of credit typically carries a base interest rate of 30-day LIBOR, or mortgage note rate plus or minus a margin. Risk is evident if there is a change in the fair value of mortgage loans originated by mortgage bankers in warehouse, the sale of which is the expected source of repayment of the borrowings under a warehouse line of credit. Residential Real Estate Loans (RES RE): Real estate loans are secured by owner-occupied 1- 4 family residences. Repayment of residential real estate loans is primarily dependent on the personal income and credit rating of the borrowers. First-lien HELOC mortgages included in this segment typically carry a base rate of 30-day LIBOR, plus a margin. Multi-Family and Healthcare Financing (MF RE): The Company engages in multi-family and healthcare financing, including construction loans, specializing in originating and servicing loans for multi-family rental and senior living properties. In addition, the Company originates loans secured by an assignment of federal income tax credits by partnerships invested in multi-family real estate projects. Construction and land loans are generally based upon estimates of costs and estimated value of the completed project and include independent appraisal reviews and a financial analysis of the developers and property owners. Sources of repayment of these loans may include permanent loans, sales of developed property or an interim loan commitment from the Company until permanent agency-eligible financing is obtained. These loans are considered to be higher risk than single-family real estate loans due to their ultimate repayment being sensitive to interest rate changes, general economic conditions and the availability of long-term financing. Credit risk in these loans may be impacted by the creditworthiness of a borrower, property values and the local economy in the Company’s market area. Repayment of these loans depends on the successful operation of a business or property and the borrower’s cash flows. Commercial Lending and Commercial Real Estate Loans (CML & CRE): The commercial lending and commercial real estate portfolio includes loans to commercial customers for use in financing working capital needs, equipment purchases and expansions, as well as loans to commercial customers to finance land and improvements. It also includes loans collateralized by mortgage servicing rights and loan sale proceeds of mortgage warehouse customers. The loans in this category are repaid primarily from the cash flow of a borrower’s principal business operation. Credit risk in these loans is driven by creditworthiness of a borrower and the economic conditions that impact the cash flow stability from business operations. PPP loans and Small Business Association (“SBA”) loans are included in this category. Agricultural Production and Real Estate Loans (AG & AGRE): Agricultural production loans are generally comprised of seasonal operating lines of credit to grain farmers to plant and harvest corn and soybeans and term loans to fund the purchase of equipment. The Company also offers long term financing to purchase agricultural real estate. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry-developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop and other farm assets as considered necessary. The Company is approved to sell agricultural loans in the secondary market through the Federal Agricultural Mortgage Corporation and uses this relationship to manage interest rate risk within the portfolio. Consumer and Margin Loans (CON & MAR): Consumer loans are those loans secured by household assets. Margin loans are those loans secured by marketable securities. The term and maximum amount for these loans are determined by considering the purpose of the loan, the margin (advance percentage against value) in all collateral, the primary source of repayment, and the borrower’s other related cash flow. Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to net interest income. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-impaired loans and is based on historical charge-off experience and expected loss from default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected in the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial and construction loans by the fair value of the collateral if the loan is collateral dependent, the loan’s obtainable market price, or the present value of expected future cash flows discounted at the loan’s effective interest rate. For impaired loans where the Company utilizes discounted cash flows to determine the level of impairment, the Company includes the entire change in the present value of cash flows as a provision for loan loss. Groups of loans with similar risk characteristics are collectively evaluated for impairment based on the group’s historical loss experience adjusted for changes in trends, conditions and other relevant factors that affect repayment of the loans. Accordingly, the Company does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. In the course of working with borrowers, the Company may choose to restructure the contractual terms of certain loans. In restructuring the loan, the Company attempts to work out an alternative payment schedule with the borrower in order to optimize collectability of the loan. A troubled debt restructuring (“TDR”) occurs when, for economic or legal reasons related to a borrower’s financial difficulties, the Company grants a concession to the borrower that it would not otherwise consider. Terms may be modified to fit the ability of the borrower to repay in line with its current financial status, and the restructuring of the loan may include the transfer of assets from the borrower to satisfy the debt, a modification of loan terms, or a combination of the two. Nonaccrual loans, including TDRs that have not met the six-month minimum performance criterion, are reported as nonperforming loans. For all loan classes, it is the Company’s policy to have any restructured loans which are on nonaccrual status prior to being restructured remain on nonaccrual status until three months of satisfactory borrower performance, at which time management would consider its return to accrual status. A loan is generally classified as nonaccrual when the Company believes that receipt of principal and interest is doubtful under the terms of the loan agreement. Most generally, this is at 90 or more days past due. With regard to determination of the amount of the allowance for credit losses, restructured loans are considered to be impaired. As a result, the determination of the amount of impaired loans for each loan portfolio segment within troubled debt restructurings is the same as detailed previously above. The following tables present, by loan portfolio segment, the activity in the allowance for loan losses for the three and six months ended June 30, 2021 and 2020 and the recorded investment in loans and impairment method as of June 30, 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At or For the Three Months Ended June 30, 2021 ​ MTG WHLOC RES RE MF RE CML & CRE AG & AGRE CON & MAR TOTAL ​ ​ (In thousands) Allowance for loan losses ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 3,321 ​ $ 3,600 $ 17,136 ​ $ 4,264 ​ $ 632 ​ $ 138 ​ $ 29,091 Provision (credit) for loan losses ​ (386) ​ 371 ​ (1,354) ​ 1,059 ​ (21) ​ 16 ​ (315) Loans charged to the allowance ​ — ​ (2) ​ — ​ (84) ​ — ​ — ​ (86) Recoveries of loans previously charged off ​ — ​ — ​ — ​ — ​ — ​ 6 ​ 6 Balance, end of period ​ $ 2,935 ​ $ 3,969 ​ $ 15,782 ​ $ 5,239 ​ $ 611 ​ $ 160 ​ $ 28,696 Ending balance: individually evaluated for impairment ​ $ — ​ $ — $ — ​ $ 1,852 ​ $ — ​ $ — ​ $ 1,852 Ending balance: collectively evaluated for impairment ​ $ 2,935 ​ $ 3,969 ​ $ 15,782 ​ $ 3,387 ​ $ 611 ​ $ 160 ​ $ 26,844 Loans ​ ​ ​ ​ ​ ​ ​ Ending balance ​ $ 1,177,940 ​ $ 806,325 ​ $ 2,970,770 ​ $ 409,710 ​ $ 92,786 ​ $ 15,392 ​ $ 5,472,923 Ending balance individually evaluated for impairment ​ $ — ​ $ 629 ​ $ — ​ $ 6,592 ​ $ 158 ​ $ 6 ​ $ 7,385 Ending balance collectively evaluated for impairment ​ $ 1,177,940 ​ $ 805,696 ​ $ 2,970,770 ​ $ 403,118 ​ $ 92,628 ​ $ 15,386 ​ $ 5,465,538 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Three Months Ended June 30, 2020 ​ MTG WHLOC RES RE MF RE CML & CRE AG & AGRE CON & MAR TOTAL ​ ​ (In thousands) Allowance for loan losses ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 2,709 ​ $ 2,062 $ 7,694 ​ $ 5,662 ​ $ 561 ​ $ 195 ​ $ 18,883 Provision (credit) for loan losses ​ 494 ​ 248 ​ 2,184 ​ (1,188) ​ 49 ​ (42) ​ 1,745 Loans charged to the allowance ​ — ​ — ​ — ​ (131) ​ — ​ — ​ (131) Balance, end of period ​ $ 3,203 ​ $ 2,310 ​ $ 9,878 ​ $ 4,343 ​ $ 610 ​ $ 153 ​ $ 20,497 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Six Months Ended June 30, 2021 ​ MTG WHLOC RES RE MF RE CML & CRE AG & AGRE CON & MAR TOTAL ​ ​ (In thousands) Allowance for loan losses ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 4,018 ​ $ 3,334 ​ $ 14,731 ​ $ 4,641 ​ $ 636 ​ $ 140 ​ $ 27,500 Provision for loan losses ​ (1,083) ​ ​ 637 ​ ​ 1,051 ​ ​ 750 ​ ​ (25) ​ ​ 18 ​ ​ 1,348 Loans charged to the allowance ​ — ​ ​ (2) ​ ​ — ​ ​ (152) ​ ​ — ​ ​ (6) ​ ​ (160) Recoveries of loans previously charged off ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ 8 ​ 8 Balance, end of period ​ $ 2,935 ​ $ 3,969 ​ $ 15,782 ​ $ 5,239 ​ $ 611 ​ $ 160 ​ $ 28,696 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the Six Months Ended June 30, 2020 ​ MTG WHLOC RES RE MF RE CML & CRE AG & AGRE CON & MAR TOTAL ​ ​ (In thousands) Allowance for loan losses ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, beginning of period ​ $ 1,913 ​ $ 2,042 ​ $ 7,018 ​ $ 4,173 ​ $ 523 ​ $ 173 ​ $ 15,842 Provision (credit) for loan losses ​ 1,290 ​ ​ 268 ​ ​ 2,860 ​ ​ 257 ​ ​ 87 ​ ​ (19) ​ 4,743 Loans charged to the allowance ​ — ​ ​ — ​ ​ — ​ ​ (131) ​ ​ — ​ ​ (1) ​ (132) Recoveries of loans previously charged off ​ — ​ ​ — ​ ​ — ​ ​ 44 ​ ​ — ​ ​ — ​ 44 Balance, end of period ​ $ 3,203 ​ $ 2,310 ​ $ 9,878 ​ $ 4,343 ​ $ 610 ​ $ 153 ​ $ 20,497 ​ The following table presents the allowance for loan losses and the recorded investment in loans and impairment method as of December 31, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ MTG WHLOC RES RE MF RE CML & CRE AG & AGRE CON & MAR TOTAL ​ ​ (In thousands) Allowance for loan losses ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Balance, December 31, 2020 ​ $ 4,018 ​ $ 3,334 ​ $ 14,731 ​ $ 4,641 ​ $ 636 ​ $ 140 ​ $ 27,500 Ending balance: individually evaluated for impairment ​ $ — ​ $ 7 ​ $ — ​ $ 1,606 ​ $ — ​ $ — ​ $ 1,613 Ending balance: collectively evaluated for impairment ​ $ 4,018 ​ $ 3,327 ​ $ 14,731 ​ $ 3,035 ​ $ 636 ​ $ 140 ​ $ 25,887 Loans ​ ​ ​ ​ ​ ​ ​ Balance, December 31, 2020 ​ $ 1,605,745 ​ $ 678,848 ​ $ 2,749,020 ​ $ 387,294 ​ $ 101,268 ​ $ 13,251 ​ $ 5,535,426 Ending balance individually evaluated for impairment ​ $ — ​ $ 2,761 ​ $ — ​ $ 9,591 ​ $ 2,100 ​ $ 12 ​ $ 14,464 Ending balance collectively evaluated for impairment ​ $ 1,605,745 ​ $ 676,087 ​ $ 2,749,020 ​ $ 377,703 ​ $ 99,168 ​ $ 13,239 ​ $ 5,520,962 ​ Internal Risk Categories In adherence with policy, the Company uses the following internal risk grading categories and definitions for loans: Average or above Acceptable – Special Mention (Watch) potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Special Mention (Watch) – COVID-19 Deferrals – This is a loan that is sound and collectable but contains potential risk because the borrower has requested to defer payments, typically for 90 days, in response to COVID-related hardships. Interest is still accruing on these loans and they were not more than 30 days late at the time the deferral was granted. Loans classified as special mention have a potential weakness that deserves management’s close attention.

Regulatory Matters
Regulatory Matters	Note 6: Regulatory Matters The Company, Merchants Bank, and FMBI are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary, actions by federal and state banking regulators that, if undertaken, could have a direct material effect on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company, Merchants Bank, and FMBI must meet specific capital guidelines that involve quantitative measures of the Company’s, Merchants Bank’s, and FMBI’s assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s, Merchants Bank’s, and FMBI’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, and other factors. Furthermore, the Company’s, Merchants Bank’s, and FMBI’s regulators could require adjustments to regulatory capital not reflected in these financial statements. On November 13, 2019, the federal regulators finalized and adopted a regulatory capital rule establishing a new community bank leverage ratio (“CBLR”), which became effective on January 1, 2020. The intent of CBLR is to provide a simple alternative measure of capital adequacy for electing qualifying depository institutions and depository institution holding companies, as directed under the Economic Growth, Regulatory Relief, and Consumer Protection Act. Under CBLR, if a qualifying depository institution or depository institution holding company elects to use such measure, such institution or holding company will be considered well capitalized if its ratio of Tier 1 capital to average total consolidated assets (i.e., leverage ratio) exceeds a 9% threshold, subject to a limited two quarter grace period, during which the leverage ratio cannot go 100 basis points below the then applicable threshold, and will not be required to calculate and report risk-based capital ratios. Eligibility criteria to utilize CBLR includes the following: ● Total assets of less than $10 billion, ● Total trading assets plus liabilities of 5% or less of consolidated assets, ● Total off-balance sheet exposures of 25% or less of consolidated assets, ● Cannot be an advanced approaches banking organization, and ● Leverage ratio greater than 9%, or temporarily prescribed threshold established in response to COVID-19. ​ In April 2020, under the CARES Act, the 9% leverage ratio threshold was temporarily reduced to 8% in response to the COVID-19 pandemic. The threshold increased to 8.5% in 2021 and will return to 9% in 2022. The Company, Merchants Bank, and FMBI elected to begin using CBLR in the first quarter of 2020 and all intend to utilize this measure for the foreseeable future and thus will not calculate or report risk-based capital ratios. On December 2, 2020 the Federal Deposit Insurance Corporation (“FDIC”) issued an interim final rule related to COVID-19 as it pertains to eligibility to utilize CBLR. The rule allows organizations with less than $10 billion in total assets as of December 31, 2019, to use the assets on that date to determine the applicability of various regulatory asset thresholds during 2020 and 2021. Management believes, as of June 30, 2021 and December 31, 2020, that the Company, Merchants Bank, and FMBI met all the regulatory capital adequacy requirements with CBLR to be classified as well-capitalized, and management is not aware of any conditions or events since the most recent regulatory notification that would change the Company’s, Merchants Bank’s, or FMBI’s category. As of June 30, 2021 and December 31, 2020, the most recent notifications from the Board of Governors of the Federal Reserve System (“Federal Reserve”) categorized the Company as well capitalized and most recent notifications from the Federal Deposit Insurance Corporation (“FDIC”) categorized Merchants Bank and FMBI as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Company’s, Merchants Bank’s, or FMBI’s category. ​ The Company’s, Merchants Bank’s, and FMBI’s actual capital amounts and ratios are presented in the following tables. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum Amount ​ ​ ​ ​ ​ ​ ​ ​ To Be Well ​ ​ ​ Actual ​ Capitalized (1) ​ ​ Amount Ratio Amount Ratio ​ ​ (Dollars in thousands) ​ June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CBLR (Tier 1) capital (1) ​ ​ ​ ​ ​ (i.e., CBLR - leverage ratio) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 1,041,631 10.9 % $ 810,065 > 8.5 % Merchants Bank ​ ​ 1,001,502 10.8 % 786,534 > 8.5 % FMBI ​ 26,691 9.6 % 23,613 > 8.5 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 1 As defined by regulatory agencies. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum Amount ​ ​ ​ ​ ​ ​ ​ ​ To Be Well ​ ​ ​ Actual ​ Capitalized (1) ​ ​ Amount Ratio Amount Ratio ​ ​ ​ (Dollars in thousands) ​ December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ CBLR (Tier 1) capital (1) ​ ​ (i.e., CBLR - leverage ratio) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 792,456 8.6 % $ 738,019 > 8 % Merchants Bank ​ 781,221 8.7 % 718,120 > 8 % FMBI ​ ​ 24,456 9.8 % 19,979 > 8 % ​ 1 As defined by regulatory agencies. ​ Failure to exceed the leverage ratio thresholds required under CBLR in the future, subject to any applicable grace period, would require the Company, Merchants Bank, and/or FMBI to return to the risk-based capital ratio thresholds previously utilized under the fully phased-in Basel III Capital Rules to determine capital adequacy.

Derivative Financial Instruments
Derivative Financial Instruments	Note 7: Derivative Financial Instruments ​ The Company uses derivative financial instruments to help manage exposure to interest rate risk and the effects that changes in interest rates may have on net income and the fair value of assets and liabilities. Forward Sales Commitments and Interest Rate Lock Commitments The Company enters into forward contracts for the future delivery of mortgage loans to third party investors and enters into interest rate lock commitments with potential borrowers to fund specific mortgage loans that will be sold into the secondary market. The forward contracts are entered into in order to economically hedge the effect of changes in interest rates resulting from the Company’s commitment to fund the loans. Each of these items are considered derivatives, but are not designated as accounting hedges, and are recorded at fair value with changes in fair value reflected in noninterest income on the condensed consolidated statements of income. The fair value of derivative instruments with a positive fair value are reported in other assets in the condensed consolidated balance sheets while derivative instruments with a negative fair value are reported in other liabilities in the condensed consolidated balance sheets. The following table presents the notional amount and fair value of interest rate locks and forward contracts utilized by the Company at June 30, 2021 and December 31, 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional ​ ​ ​ ​ ​ Fair Value ​ ​ Amount ​ Balance Sheet Location ​ Asset ​ Liability June 30, 2021 ​ (In thousands) ​ ​ ​ ​ ​ (In thousands) Interest rate lock commitments $ 105,076 ​ ​ Other assets/liabilities ​ $ 487 ​ $ 54 Forward contracts $ 107,364 ​ ​ Other assets/liabilities ​ 8 ​ ​ 223 ​ ​ ​ ​ ​ ​ ​ $ 495 ​ $ 277 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional ​ ​ ​ ​ ​ Fair Value ​ ​ Amount ​ Balance Sheet Location ​ Asset ​ Liability December 31, 2020 ​ (In thousands) ​ ​ ​ ​ ​ (In thousands) Interest rate lock commitments $ 412,043 ​ ​ Other assets/liabilities ​ $ 6,131 ​ $ — Forward contracts $ 304,024 ​ ​ Other assets/liabilities ​ — ​ ​ 2,682 ​ ​ ​ ​ ​ ​ ​ $ 6,131 ​ $ 2,682 ​ Fair values of these derivative financial instruments were estimated using changes in mortgage interest rates from the date the Company entered into the interest rate lock commitment and the balance sheet date.

These derivatives include interest rate swaps. The Company manages the risk associated with these contracts by entering into an equal and offsetting derivative with a third-party dealer. These derivatives generally work together as an economic interest rate hedge, but the Company does not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred, typically resulting in no net earnings impact. The fair values of derivative assets and liabilities related to derivatives for customers with interest rate swaps were recorded in the condensed consolidated balance sheets as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional ​ ​ ​ ​ ​ Fair Value ​ ​ Amount ​ Balance Sheet Location ​ Asset ​ Liability ​ ​ (In thousands) ​ ​ ​ ​ ​ (In thousands) June 30, 2021 $ 86,387 ​ ​ Other assets/liabilities ​ $ 2,089 ​ $ 2,089 December 31, 2020 $ 82,726 ​ ​ Other assets/liabilities ​ $ 3,170 ​ $ 3,170 ​ If there is a net gain or loss, the gross gains and losses on these derivative assets and liabilities are recorded in Other Noninterest income and Other Noninterest expense in the condensed consolidated statements of income. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ June 30, ​ June 30, ​ 2021 2020 2021 2020 ​ ​ (In thousands) ​ ​ (In thousands) Gross swap gains ​ $ 195 ​ $ 634 ​ $ 1,081 ​ $ 3,337 Gross swap losses ​ ​ (195) ​ ​ (634) ​ (1,081) ​ ​ (3,337) Net swap gains (losses) ​ $ — ​ $ — ​ $ — ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The Company pledged $3.9 million in collateral to secure its obligations under swap contracts at June 30, 2021 and December 31, 2020.

For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Mortgage Loans in Process of Securitization and Available for Sale Securities Where quoted market prices are available in an active market, securities such as U.S. Treasuries are classified within Level 1 of the valuation hierarchy. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independently sourced market parameters, including, but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy including federal agencies, mortgage-backed securities, municipal securities and Federal Housing Administration participation certificates. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Loans Held for Sale Certain loans held for sale at fair value are saleable into the secondary mortgage markets and their fair values are estimated using observable quoted market or contracted prices, or market price equivalents, which would be used by other market participants. These saleable loans are considered Level 2. Mortgage Servicing Rights Mortgage servicing rights do not trade in an active, open market with readily observable prices. Accordingly, fair value is estimated using discounted cash flow models having significant inputs of discount rate, prepayment speed, and default rate. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the hierarchy. The Chief Financial Officer’s (CFO) office contracts with a pricing specialist to generate fair value estimates on a quarterly basis. The CFO’s office challenges the reasonableness of the assumptions used and reviews the methodology to ensure the estimated fair value complies with accounting standards generally accepted in the United States. Derivative Financial Instruments The Company estimates the fair value of interest rate lock commitments based on the value of the underlying mortgage loan, quoted mortgage backed security prices, estimates of the fair value of the mortgage servicing rights, and an estimate of the probability that the mortgage loan will fund within the terms of the interest rate lock commitment, net of expenses. With respect to its interest rate lock commitments, management determined that a Level 3 classification was most appropriate based on the various significant unobservable inputs utilized in estimating the fair value of its interest rate lock commitments. The Company estimates the fair value of forward sales commitments based on market quotes of mortgage backed security prices for securities similar to the ones used, which are considered Level 2. The fair value of interest rate swaps is based on prices that are obtained from a third party that uses observable market inputs, thereby supporting a Level 2 classification. Changes in fair value of the Company’s derivative financial instruments are recognized through noninterest income and/or noninterest expenses on its condensed consolidated statement of income.

For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below. Collateral-Dependent Impaired Loans, Net of Allowance for Loan Losses The estimated fair value of collateral-dependent impaired loans is based on the appraised fair value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. The Company considers the appraisal or evaluation as the starting point for determining fair value and then considers other factors and events in the environment that may affect the fair value. Appraisals of the collateral underlying collateral-dependent loans are obtained when the loan is determined to be collateral-dependent and subsequently as deemed necessary by the Company’s Chief Credit Officer’s (CCO) office. Appraisals are reviewed for accuracy and consistency by the CCO’s office. Appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral. These discounts and estimates are developed by the CCO’s office by comparison to historical results. Unobservable (Level 3) Inputs: The following table presents quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements other than goodwill. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Valuation ​ ​ ​ ​ ​ Weighted ​ Fair Value Technique Unobservable Inputs ​ Range Average ​ ​ (In thousands) ​ ​ ​ ​ ​ ​ ​ ​ At June 30, 2021: ​ ​ ​ ​ ​ ​ Collateral-dependent impaired loans ​ $ 3,807 Market comparable properties Marketability discount ​ 49% 49% Mortgage servicing rights - Multi-family ​ $ 78,097 Discounted cash flow Discount rate ​ 8% - 13% 9% ​ ​ ​ ​ ​ ​ ​ Constant prepayment rate ​ 0% - 43% 3% Mortgage servicing rights - Single-family ​ $ 20,234 Discounted cash flow Mortgage yield ​ 9% - 10% ​ 9% ​ ​ ​ ​ ​ ​ ​ Constant prepayment rate ​ 11% - 14% ​ 12% Derivative assets - interest rate lock commitments ​ $ 487 Discounted cash flow Loan closing rates ​ 63% - 99% 82% Derivative liabilities - interest rate lock commitments ​ $ 54 Discounted cash flow Loan closing rates ​ 63% - 99% 82% ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At December 31, 2020: ​ ​ ​ ​ ​ ​ Collateral-dependent impaired loans ​ $ 4,059 Market comparable properties Marketability discount ​ 43% 43% Mortgage servicing rights - Multi-family ​ $ 73,569 Discounted cash flow Discount rate ​ 8% - 13% 9% ​ ​ ​ ​ ​ ​ ​ Constant prepayment rate ​ 2% - 43% 4% Mortgage servicing rights - Single-family ​ $ 9,035 Discounted cash flow Discount rate ​ 11% ​ 11% ​ ​ ​ ​ ​ ​ ​ Constant prepayment rate ​ 8% - 35% ​ 16% Derivative assets - interest rate lock commitments ​ $ 6,131 Discounted cash flow Loan closing rates ​ 55% - 99% 75% ​ Sensitivity of Significant Unobservable Inputs The following is a discussion of the sensitivity of significant unobservable inputs, the interrelationships between those inputs and other unobservable inputs used in recurring fair value measurement, and of how those inputs might magnify or mitigate the effect of changes in the unobservable inputs on the fair value measurement. Mortgage Servicing Rights The most significant unobservable inputs used in the fair value measurement of the Company’s mortgage servicing right are discount rates and constant prepayment rates. These two inputs can drive a significant amount of a market participant’s valuation of mortgage servicing rights. Significant increases (decreases) in the discount rate or assumed constant prepayment rates used to value mortgage servicing rights would decrease (increase) the value derived. Fair Value of Financial Instruments The following table presents the carrying amount and estimated fair values of the Company’s financial instruments not carried at fair value and the level within the fair value hierarchy in which the fair value measurements fall at June 30, 2021 and December 31, 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements Using ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices in ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Active Markets ​ Other ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ for Identical ​ Observable ​ Unobservable ​ ​ Carrying ​ Fair ​ Assets ​ Inputs ​ Inputs Assets Value Value (Level 1) (Level 2) (Level 3) ​ ​ (In thousands) June 30, 2021 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 402,049 ​ $ 402,049 ​ $ 402,049 ​ $ — ​ $ — Securities purchased under agreements to resell ​ 6,507 ​ 6,507 ​ — ​ 6,507 ​ — FHLB stock ​ 70,767 ​ 70,767 ​ — ​ 70,767 ​ — Loans held for sale ​ 2,928,767 ​ 2,928,767 ​ — ​ 2,928,767 ​ — Loans, net ​ 5,444,227 ​ 5,399,967 ​ — ​ — ​ 5,399,967 Interest receivable ​ 22,068 ​ 22,068 ​ — ​ 22,068 ​ — Financial liabilities: ​ ​ ​ ​ ​ ​ Deposits ​ 8,039,578 ​ 8,041,139 ​ 7,508,693 ​ 532,446 ​ — Short-term subordinated debt ​ 14,960 ​ 14,960 ​ — ​ 14,960 ​ — FHLB advances ​ 607,003 ​ 607,124 ​ — ​ 607,124 ​ — Other borrowing ​ ​ 79,410 ​ ​ 79,410 ​ ​ — ​ ​ 79,410 ​ ​ — Interest payable ​ 2,471 ​ 2,471 ​ — ​ 2,471 ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 179,728 ​ $ 179,728 ​ $ 179,728 ​ $ — ​ $ — Securities purchased under agreements to resell ​ 6,580 ​ 6,580 ​ — ​ 6,580 ​ — FHLB stock ​ 70,656 ​ 70,656 ​ — ​ 70,656 ​ — Loans held for sale ​ 3,030,110 ​ 3,030,110 ​ — ​ 3,030,110 ​ — Loans, net ​ 5,507,926 ​ 5,484,824 ​ — ​ — ​ 5,484,824 Interest receivable ​ 21,770 ​ 21,770 ​ — ​ 21,770 ​ — Financial liabilities: ​ ​ ​ ​ ​ ​ Deposits ​ 7,408,066 ​ 7,410,759 ​ 7,051,413 ​ 359,346 ​ — Short-term subordinated debt ​ 14,960 ​ 14,960 ​ — ​ 14,960 ​ — FHLB advances ​ 1,221,071 ​ 1,221,870 ​ — ​ 1,221,870 ​ — Federal Reserve discount window/PPPLF advances ​ ​ 112,225 ​ ​ 112,225 ​ ​ — ​ ​ 112,225 ​ ​ — Interest payable ​ 1,476 ​ 1,476 ​ — ​ 1,476 ​ — ​

FASB ASU 2016-02, Leases In February 2016, the Financial Accounting Standards Board (the “FASB”) issued ASU 2016-02, “Leases.” Under the new guidance, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: ● A lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and ● A right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, “Revenue from Contracts with Customers.” The new lease guidance simplified the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Lessees will no longer be provided with a source of off- balance sheet financing. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. As an emerging growth company, the amendments in ASU 2016- 02 are effective for fiscal years beginning after December 15, 2021, and for interim periods for years beginning after January 1, 2022. The Company is continuing to evaluate the impact of adopting this new guidance, but it does not expect the adoption to have a material impact on the Company’s financial position or results of operations. FASB ASU 2016-13, Financial Instruments—Credit Losses In June 2016, the FASB issued ASU 2016-13, “Financial Instruments—Credit Losses”, commonly referred to as “CECL”. The amendments in this ASU replace the incurred loss model with a methodology that reflects the “current expected credit losses” over the life of the loan and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates. ASU 2016-13 replaces the incurred loss impairment methodology with a new methodology that reflects expected credit losses over the lives of the loans and requires consideration of a broader range of information to form credit loss estimates. The ASU requires an organization to estimate all expected credit losses for financial assets measured at amortized cost, including loans and held-to-maturity debt securities, based on historical experience, current conditions, and reasonable and supportable forecasts. Additional disclosures are required. As an emerging growth company, the amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Because the Company’s status as an emerging growth company is expected to expire on December 31, 2022, this standard will likely be implemented by December 31, 2022. The Company has established a cross-functional committee that has developed a project plan to review modeling data currently available and technology needed to ensure compliance with this standard. The committee has contracted with a vendor to assist in generating specific loan level details within our core systems, as well as compiling peer and industry data that would be useful in our modeling forecasts. The Company generally expects to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the new standard is effective, and is progressing towards determining the magnitude of any such one-time adjustment or the overall impact of the new guidance on the Company’s consolidated financial statements. FASB ASU 2019-12 - Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes ​ In December 2019, the FASB issued ASU No. 2019-12. This ASU removes specific exceptions to the general principles in Topic 740 in GAAP. It eliminates the need for an organization to analyze whether the following apply in a given period: (1) exception to the incremental approach for intraperiod tax allocation; (2) exceptions to accounting for basis differences when there are ownership changes in foreign investments; and (3) exception in interim period income tax accounting for year-to-date losses that exceed anticipated losses. The ASU also improves financial statement preparers’ application of income tax-related guidance and simplifies GAAP for: (1) franchise taxes that are partially based on income; (2) transactions with a government that result in a step up in the tax basis of goodwill; (3) separate financial statements of legal entities that are not subject to tax; and (4) enacted changes in tax laws in interim periods. ​ As an emerging growth company, the amendments in this update become effective for fiscal years beginning after December 15, 2021, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the impact of adopting the new guidance but does not expect it to have a material impact on the consolidated financial statements. ​ FASB ASU 2020-04 - Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting ​ 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 ​ ● A change in a contract’s reference interest rate would be accounted for as a continuation of that contract rather than as the creation of a new one for contracts, including loans, debt, leases, and other arrangements, that meet specific criteria. ​ ● When updating its hedging strategies in response to reference rate reform, an entity would be allowed to preserve its hedge accounting. ​ Entities may apply this ASU as of the beginning of an interim period that includes the March 12, 2020 issuance date of the ASU, through December 31, 2022. The Company is in the process of implementing a transition plan to identify and modify its loans and other financial instruments with attributes that are either directly or indirectly influenced by LIBOR. The Company believes the adoption of this guidance on activities subsequent to December 31, 2020 through December 31, 2022 would not have a material impact on the consolidated financial statements.

Basis of Presentation
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements include the accounts of Merchants Bancorp, a registered bank holding company (the “Company”) and its wholly owned subsidiaries, Merchants Bank of Indiana (“Merchants Bank”) and Farmers-Merchants Bank of Illinois (“FMBI”). Merchants Bank’s primary operating subsidiaries include Merchants Capital Corp. (‘MCC”) and Merchants Capital Servicing, LLC (“MCS”). All direct and indirectly owned subsidiaries owned by Merchants Bancorp are collectively referred to as the “Company”. The accompanying unaudited condensed consolidated balance sheet of the Company as of December 31, 2020, which has been derived from audited financial statements, and unaudited condensed consolidated financial statements of the Company as of June 30, 2021 and for the three and six months ended June 30, 2021 and 2020, were prepared in accordance with the instructions for Form 10-Q and Article 10 of Regulation S-X and, therefore, do not include information or footnotes necessary for a complete presentation of financial position, results of operations and cash flows in conformity with accounting principles generally accepted in the United States of America. Accordingly, these condensed financial statements should be read in conjunction with the audited financial statements and notes thereto of the Company as of and for the year ended December 31, 2020 in its Annual Report on Form 10-K. Reference is made to the accounting policies of the Company described in the Notes to the Financial Statements contained in the Annual Report on Form 10-K. In the opinion of management, all adjustments (consisting only of normal recurring adjustments) which are necessary for a fair presentation of the unaudited financial statements have been included to present fairly the financial position as of June 30, 2021
Principles of Consolidation	Principles of Consolidation The unaudited condensed consolidated financial statements as of and for the period ended June 30, 2021 and 2020 include results from the Company, and its wholly owned subsidiaries, Merchants Bank, and FMBI. Also included are Merchants Bank’s primary operating subsidiaries, MCC and MCS, as well as all 100% directly and indirectly owned subsidiaries owned by Merchants Bancorp. Additionally, the unaudited condensed consolidated financial statements include consolidated results from certain entities primarily involved in single-family debt financing until January 30, 2021, while the Company was deemed to be a primary beneficiary. A primary beneficiary is defined as, the party that has both the power to direct the activities that most significantly impact the entity, and an interest that could be significant to the entity. To determine if an interest could be significant to the entity, both qualitative and quantitative factors regarding the nature, size and form of our involvement with the entity are evaluated. All significant intercompany accounts and transactions have been eliminated in consolidation. On February 1, 2021, the Company’s debt fund entities were restructured in such a way that its ownership and participation was significantly reduced with the inclusion of additional, unrelated investors and the Company was no longer classified as a primary beneficiary. Accordingly, results from these entities were no longer consolidated after this date, in accordance with the consolidation guidelines of the Accounting Standards Update of Topic 810. Following the deconsolidation, the carrying value of assets and liabilities of these entities were removed from the consolidated balance sheet, and the continuing investments were recorded at fair value at the date of deconsolidation. The total amount deconsolidated from the balance sheet included net assets of approximately $10 million, consisting primarily of $66.6 million in loans receivable, and $52.7 million in borrowings with Merchants Bank that was previously eliminated in consolidation. The fair value of its continuing investments was approximately $10 million and has been reported in Other Assets after deconsolidation. The estimated fair value was determined based on third-party evaluations of similar assets in the underlying business. The difference between the fair value of these deconsolidated entities and their carrying value was deemed to be immaterial, resulting in no gain or loss on deconsolidation. The maximum loss exposure that would be absorbed by the Company in the event that these unconsolidated investments were deemed worthless is approximately $10.0 million at June 30, 2021. These continuing investments after deconsolidation are classified as variable interest entities, will not be consolidated, and are accounted for under the equity method of accounting. The Company will analyze whether its entities are the primary beneficiary on an ongoing basis. Changes in facts and circumstances occurring since the previous primary beneficiary determination will be considered as part of this ongoing assessment.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America 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. Actual results could differ from those estimates.
Reclassifications	Reclassifications ​ Certain reclassifications may have been made to the 2020 financial statements to conform to the financial statement presentation as of and for the three and six months ended June 30, 2021. These reclassifications had no effect on net income.
