THE COMPANY

Great Southern Bancorp, Inc.

Great Southern Bancorp, Inc. ("Bancorp" or "Company") is a bank holding company, a financial holding company and the parent of Great Southern Bank ("Great Southern" or the "Bank"). Bancorp was incorporated under the laws of the State of Delaware in July 1989 as a unitary savings and loan holding company. The Company became a one-bank holding company on June 30, 1998, upon the conversion of Great Southern to a Missouri-chartered trust company. In 2004, Bancorp was re-incorporated under the laws of the State of Maryland.

As a Maryland corporation, the Company is authorized to engage in any activity that is permitted by the Maryland General Corporation Law and not prohibited by law or regulatory policy. The Company currently conducts its business as a financial holding company. Through the financial holding company structure, it is possible to expand the size and scope of the financial services offered by the Company beyond those offered by the Bank. The financial holding company structure provides the Company with greater flexibility than the Bank has to diversify its business activities, through existing or newly formed subsidiaries, or through acquisitions of or mergers with other financial institutions as well as other companies. At December 31, 2020, Bancorp's consolidated total assets were $5.53 billion, consolidated net loans were $4.30 billion, consolidated deposits were $4.52 billion and consolidated total stockholders' equity was $629.7 million. For details about the Company’s assets, revenues and profits for each of the last five fiscal years, see Item 6. “Selected Financial Data.” The assets of the Company at the holding company level consist primarily of the stock of Great Southern and cash.

Through the Bank and subsidiaries of the Bank, the Company primarily offers a variety of banking and banking-related services, which are discussed further below. The activities of the Company are funded by retained earnings and through dividends from Great Southern. Activities of the Company may also be funded through borrowings from third parties, sales of additional securities or through income generated by other activities of the Company.

The executive offices of the Company are located at 1451 East Battlefield, Springfield, Missouri 65804, and its telephone number at that address is (417) 887-4400.

Great Southern Bank

Great Southern was formed as a Missouri-chartered mutual savings and loan association in 1923, and, in 1989, converted to a Missouri-chartered stock savings and loan association. In 1994, Great Southern changed to a federal savings bank charter and then, on June 30, 1998, changed to a Missouri-chartered trust company (the equivalent of a commercial bank charter). Headquartered in Springfield, Missouri, Great Southern offers a broad range of banking services through its 94 banking centers located in southern and central Missouri; the Kansas City, Missouri area; the St. Louis, Missouri area; eastern Kansas; northwestern Arkansas; the Minneapolis, Minnesota area and eastern, western and central Iowa. At December 31, 2020, the Bank had total assets of $5.52 billion, net loans of $4.31 billion, deposits of $4.63 billion and equity capital of $698.4 million, or 12.6% of total assets. Its deposits are insured by the Deposit Insurance Fund ("DIF") to the maximum levels permitted by the Federal Deposit Insurance Corporation (“FDIC”).

The size and complexity of the Bank’s operations increased substantially in 2009 with the completion of two FDIC-assisted transactions, and again in 2011, 2012 and 2014 with the completion of another FDIC-assisted transaction in each of those years. In 2009, the Bank entered into two separate purchase and assumption agreements (including loss sharing) with the FDIC to assume all of the deposits (excluding brokered deposits) and certain liabilities and acquire certain assets of TeamBank, N.A. and Vantus Bank. In these two transactions we acquired assets with a fair value of approximately $499.9 million (approximately 18.8% of the Company’s total consolidated assets at acquisition) and $294.2 million (approximately 8.8% of the Company’s total consolidated assets at acquisition), respectively, and assumed liabilities with a fair value of $610.2 million (approximately 24.9% of the Company’s total consolidated assets at acquisition) and $440.0 million (approximately 13.2% of the Company’s total consolidated assets at acquisition), respectively. They also resulted in gains of $43.9 million and $45.9 million, respectively, which were included in Noninterest Income in the Company’s Consolidated Statement of Income for the year ended December 31, 2009. Prior to these acquisitions, the Company operated banking centers in Missouri with loan production offices in Arkansas and Kansas. These acquisitions added 31 banking centers and expanded our footprint to cover five states – Iowa, Kansas, Missouri, Arkansas and Nebraska. In 2011, the Bank entered into a purchase and assumption agreement (including loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Sun Security Bank, which added locations in southern Missouri and St. Louis. In this transaction we acquired assets with a fair value of approximately $248.9 million (approximately 7.3% of the Company’s total consolidated assets at acquisition) and assumed liabilities with a fair value of $345.8 million (approximately 10.1% of the Company’s total consolidated assets at acquisition). It also resulted in a gain of $16.5 million which was included in Noninterest Income in the Company’s Consolidated Statement of Income for the year ended December 31, 2011. In 2012, the Bank entered into a purchase and assumption agreement (including loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Inter Savings Bank, FSB (“InterBank”), which added four locations in the greater Minneapolis, Minnesota area and represented a new market for the Company. In this transaction we acquired assets with a fair value of approximately $364.2 million (approximately 9.4% of the Company’s total consolidated assets at acquisition) and assumed liabilities with a fair value of approximately $458.7 million (approximately 11.9% of the Company’s total consolidated assets at acquisition). It also resulted in a gain of $31.3 million which was included in Noninterest Income in the Company’s Consolidated Statement of Income for the year ended December 31, 2012.

In 2014, the Bank entered into a purchase and assumption agreement (without loss sharing) with the FDIC to assume all of the deposits and certain liabilities and acquire certain assets of Valley Bank (“Valley”), which added five locations in the Quad Cities area of eastern Iowa and six locations in central Iowa, primarily in the Des Moines market area. These represented new markets for the Company in eastern Iowa and enhanced our market presence in central Iowa. In this transaction we acquired assets with a fair value of approximately $378.7 million (approximately 10.0% of the Company’s total consolidated assets at acquisition) and assumed liabilities with a fair value of approximately $367.9 million (approximately 9.8% of the Company’s total consolidated assets at acquisition). It also resulted in a gain of $10.8 million which was included in Noninterest Income in the Company’s Consolidated Statement of Income for the year ended December 31, 2014.

Also in 2014, the Bank entered into a purchase and assumption agreement to acquire certain assets and depository accounts from Neosho, Mo.-based Boulevard Bank (“Boulevard”), which added one location in the Neosho, Mo. market, where the Company already operated a banking center. In this transaction, which was completed in 2014, we acquired assets (primarily cash and cash equivalents) with a fair value of approximately $92.5 million (approximately 2.6% of the Company’s total consolidated assets at acquisition) and assumed liabilities (all deposits and related accrued interest) with a fair value of approximately $93.3 million (approximately 2.6% of the Company’s total consolidated assets at acquisition). This acquisition resulted in recognition of $790,000 of goodwill.

The Company also opened commercial loan production offices in Dallas, Texas and Tulsa, Oklahoma during 2014. The primary products offered in these offices are commercial real estate, commercial business and commercial construction loans.

In 2015, the Company announced plans to consolidate operations of 16 banking centers into other nearby Great Southern banking center locations. As part of an ongoing performance review of its entire banking center network, Great Southern evaluated each location for a number of criteria, including access and availability of services to affected customers, the proximity of other Great Southern banking centers, profitability and transaction volumes, and market dynamics. Subsequent to this announcement, the Bank entered into separate definitive agreements to sell two of the 16 banking centers, including all of the associated deposits (totaling approximately $20 million), to separate bank purchasers. One of those sale transactions was completed on February 19, 2016 and the other was completed on March 18, 2016. The closing of the remaining 14 facilities, which resulted in the transfer of approximately

$127 million in deposits and banking center operations to other Great Southern locations, occurred at the close of business on January 8, 2016.

Also in 2015, the Company announced that it entered into a purchase and assumption agreement to acquire 12 branches, including related loans, and to assume related deposits in the St. Louis, Mo., area from Cincinnati-based Fifth Third Bank. The acquisition was completed at the close of business on January 29, 2016. The deposits assumed totaled approximately $228 million and had a weighted average rate of approximately 0.28%. The loans acquired totaled approximately $159 million and had a weighted average yield of approximately 3.92%.

The loss sharing agreements related to the FDIC-assisted transactions in 2009, 2011 and 2012 added to the complexity of our operations by creating the need for new employees and processes to ensure compliance with the loss sharing agreements and the collection of problem assets acquired. See Note 4 included in Item 8. “Financial Statements and Supplementary Information” for a more detailed discussion of these FDIC-assisted transactions and the loss sharing agreements. The loss sharing agreements related to the 2009 and 2011 FDIC-assisted transactions were terminated during 2016. The loss sharing agreements related to the 2012 FDIC-assisted transaction were terminated during 2017. See “Loss Share Agreements” below for additional information regarding the termination of these agreements.

The Company opened a commercial loan production office in Chicago, Illinois during 2017. The primary products offered in this office are commercial real estate, commercial business and commercial construction loans.

In March 2018, the Bank entered into a definitive agreement to sell its four banking centers, including all of the associated deposits (totaling approximately $56 million), in the Omaha, Nebraska market to Lincoln, Nebraska-based West Gate Bank. This sale transaction was completed in July 2018.

The Company opened two commercial loan production offices – one in Denver, Colorado and one in Atlanta, Georgia – in late 2018. The primary products offered in these offices are commercial real estate, commercial business and commercial construction loans.

In March 2019, the Company ceased operating its indirect automobile financing unit. Market forces, including strong rate competition for well-qualified borrowers, made indirect lending through automobile dealerships a significant challenge to efficient and profitable operations over the long term. Indirect loan balances significantly declined in 2018 and 2019 after tightened underwriting guidelines were implemented in the latter part of 2016, in response to more challenging consumer credit conditions. The Company continues to offer direct consumer loans through its banking center network.

In April 2019, the Company consolidated its Fayetteville, Ark., location into its Rogers, Ark., banking center. The Company now operates one banking center in Arkansas. In September 2019, the Company consolidated its Ames, Iowa, banking center into its North Ankeny, Iowa office. The Company entered the Ames market with only one banking center through the Valley Bank FDIC-assisted acquisition in 2014.

In April 2020, the Company was notified by its landlord that the Great Southern banking centers located inside the Hy-Vee stores at 2900 Devils Glen Rd in Bettendorf, Iowa, and 2351 W. Locust St. in Davenport, Iowa, must permanently cease operations due to store infrastructure changes. Customer accounts were transferred to nearby offices. Great Southern now operates three banking centers in the Quad Cities market area – two in Davenport and one in Bettendorf.

In August 2020, remodeling of the downtown office at 1900 Main in Parsons, Kansas, was completed, which included the addition of drive-thru banking lanes. With this completion, the nearby drive-thru facility was consolidated into the downtown office, leaving one location serving the Parsons market.

Great Southern is principally engaged in the business of originating commercial real estate loans, construction loans, other commercial loans, residential real estate loans and consumer loans and funding these loans by attracting deposits from the general public, obtaining brokered deposits and through borrowings from the Federal Home Loan Bank of Des Moines (the "FHLBank") and others.

For many years, Great Southern has followed a strategy of emphasizing loan origination through residential, commercial and consumer lending activities in its market areas. The goal of this strategy is to be one of the leading providers of financial services in Great Southern’s market areas, while simultaneously diversifying assets and reducing interest rate risk by originating and holding

adjustable-rate loans and fixed-rate loans, primarily with terms of five years or less, in its portfolio and by selling longer-term fixed-rate single-family mortgage loans in the secondary market. The Bank continues to emphasize real estate lending while also expanding and increasing its originations of commercial business loans.

The corporate office of the Bank is located at 1451 East Battlefield, Springfield, Missouri 65804 and its telephone number at that address is (417) 887-4400.

Market Areas

The Company currently operates 94 full-service retail banking offices, serving more than 141,000 households in six states – Missouri, Iowa, Kansas, Minnesota, Arkansas and Nebraska. The Company also operates commercial loan production offices in Atlanta, Chicago, Dallas, Denver, Omaha, Neb., and Tulsa, Okla., and a mortgage lending office in Springfield, Mo.

The Company regularly evaluates its banking center network and lines of business to ensure that it is serving customers in the best way possible. The banking center network constantly evolves with changes in customer needs and preferences, emerging technology and local market developments. In response to these changes, the Company opens banking centers and invests resources where customer demand leads, and from time to time, consolidates banking centers when market conditions dictate.

Great Southern’s largest concentration of deposits and loans are in the Springfield, Mo., and St. Louis, Mo., market areas. In the last several years, the Company’s deposit and loan portfolios have become more diversified because of its participation in five FDIC-assisted acquisitions and organic growth. The FDIC-assisted acquisitions significantly expanded the Company’s geographic footprint, which prior to 2009 was primarily in southwest and central Missouri, by adding operations in Iowa, Kansas, Minnesota and Nebraska. In 2018, the Company sold four banking centers in the Omaha, Neb., metropolitan market to a Nebraska-based bank. A commercial loan production office remains in Omaha. In April 2019, the Fayetteville, Ark., banking center was consolidated into the Rogers, Ark., office, leaving one office in Arkansas. Besides the Springfield and St. Louis market areas, the Company has deposit and loan concentrations in the following market areas: Kansas City, Mo.; Sioux City, Iowa; Des Moines, Iowa; Northwest Arkansas; Minneapolis, Minn.; and Eastern Iowa in the area known as the "Quad Cities."  Deposits and loans are also generated in banking centers in rural markets in Missouri, Iowa, and Kansas.

At December 31, 2020, the Company's total deposits were $4.52 billion. At that date, the Company had deposits in Missouri of $3.26 billion, which included its two largest deposit concentrations, in the Springfield and St. Louis areas, with $1.93 billion and $622 million, respectively. The Company also had deposits of $660 million in Iowa, $321 million in Kansas, $226 million in Minnesota, $24 million in Nebraska and $23 million in Arkansas.

The Company also has commercial loan production offices in Atlanta, Chicago, Dallas, Denver, Omaha, Neb. and Tulsa, Okla. These offices generate a significant percentage of the Company’s commercial loan production. Commercial lending groups in our Kansas City, Mo., Des Moines, Iowa, Minneapolis, Minn., Springfield, Mo., and St. Louis, Mo., banking offices also generate a significant percentage of the Company’s commercial loan production.

Lending Activities

General

From its beginnings in 1923 through the early 1980s, Great Southern primarily made long-term, fixed-rate residential real estate loans that it retained in its loan portfolio. Beginning in the early 1980s, Great Southern increased its efforts to originate short-term and adjustable-rate loans. Beginning in the mid-1980s, Great Southern increased its efforts to originate commercial real estate and other

Table of Contents

residential loans, primarily with adjustable rates or shorter-term fixed rates. In addition, some competitor banking organizations merged with larger institutions and changed their business practices or moved operations away from the Springfield, Mo. area, and others consolidated operations from the Springfield, Mo. area to larger cities. This provided Great Southern expanded opportunities in residential and commercial real estate lending as well as in the origination of commercial business and consumer loans.

In addition to originating loans, the Bank has expanded and enlarged its relationships with smaller banks and other peer banks to purchase participations (at par, generally with no servicing costs) in loans these other banks originate but are unable to retain the entire balance in their portfolios due to capital or borrower relationship size limitations. The Bank uses the same underwriting guidelines in evaluating these participations as it does in its direct loan originations. At December 31, 2020, the balance of participation loans purchased and held in the portfolio, excluding FDIC-assisted acquired loans, was $270.5 million, or 6.3% of the total loan portfolio. All of these participation loans were performing at December 31, 2020.

One of the principal historical lending activities of Great Southern is the origination of fixed and adjustable-rate conventional residential real estate loans to enable borrowers to purchase or refinance owner-occupied homes. Great Southern originates a variety of conventional, residential real estate mortgage loans, principally in compliance with Freddie Mac and Fannie Mae standards for resale in the secondary market. Great Southern promptly sells most of the fixed-rate residential mortgage loans that it originates. To date, Great Southern has not experienced difficulties selling these loans in the secondary market and has had minimal requests for repurchase. Depending on market conditions, the ongoing servicing of these loans is at times retained by Great Southern, but generally servicing is released to the purchaser of the loan. Great Southern retains in its portfolio substantially all of the adjustable-rate mortgage loans that it originates.

Another principal lending activity of Great Southern is the origination of commercial real estate, other residential (multi-family) and commercial construction loans. Since the early 1990s, commercial real estate, other residential (multi-family) and commercial construction loans have represented the largest percentage of the loan portfolio. At December 31, 2020, commercial real estate, other residential (multi-family) and commercial construction loans, excluding loans acquired in FDIC-assisted transactions, accounted for approximately 30%, 19% and 18%, respectively, of the total portfolio. Of the portfolio of acquired loans, commercial real estate loans (net of fair value discounts) accounted for approximately 1% of the total portfolio at December 31, 2020.

In addition, Great Southern in recent years has increased its emphasis on the origination of other commercial loans and home equity loans, and also issues letters of credit. Letters of credit are contingent obligations and are not included in the Bank's loan portfolio. See "-- Other Commercial Lending," "- Classified Assets," and "Loan Delinquencies and Defaults" below.

The percentage of collateral value Great Southern will loan on real estate and other property varies based on factors including, but not limited to, the type of property and its location and the borrower's credit history. As a general rule, Great Southern will loan up to 95% of the appraised value on one-to four-family residential properties. Typically, private mortgage insurance is required for loan amounts above the 80% level. At December 31, 2020 and 2019, loans secured by second liens on residential properties were $87.3 million, or 2.0%, and $106.5 million, or 2.5%, respectively, of our total loan portfolio. For commercial real estate and other residential real property loans, Great Southern may loan up to 85% of the appraised value. The origination of loans secured by other property is considered and determined on an individual basis by management with the assistance of any industry guides and other information which may be available. Collateral values are reappraised or reassessed as loans are renewed or when significant events indicating potential impairment occur. On a quarterly basis, management reviews impaired loans to determine whether updated appraisals or reassessments are necessary based on loan performance, collateral type and guarantor support. While not specifically required by our policy, we seek to obtain cross-collateralization of loans to a borrower when it is available and it is most frequently done on commercial real estate loans.

Loan applications are approved at various levels of authority, depending on the type, amount and loan-to-value ratio of the loan. Loan commitments of more than $750,000 (or loans exceeding the Freddie Mac loan limit in the case of fixed-rate, one- to four-family residential loans for resale) must be approved by Great Southern’s loan committee. The loan committee is comprised of the Chief Executive Officer of the Bank, the Chief Credit Officer of the Bank (chairman of the committee), and other senior officers of the Bank involved in lending activities. All loans, regardless of size or type, are required to conform to certain minimum underwriting standards to assure portfolio quality. These standards and procedures include, but are not limited to, an analysis of the borrower’s financial condition, collateral, repayment ability, verification of liquid assets and credit history as required by loan type. It has been, and continues to be, our practice to verify information from potential borrowers regarding assets, income or payment ability and credit ratings as applicable and as required by the authority approving the loan. Underwriting standards also include loan-to-value ratios which vary depending on collateral type, debt service coverage ratios or debt payment to income ratios, where applicable, credit histories, use of guaranties and other recommended terms relating to equity requirements, amortization, and maturity. Generally, deviations from approved underwriting standards may only be allowed when doing so is not in violation of regulations or statutes and when appropriate lending authority is obtained. The loan committee reviews all new loan originations in excess of lender approval authorities. For secured loans originated and held, most lenders have approval authorities of $250,000 or below while fourteen senior lenders have approval authority of varying amounts up to $1 million. Lender approval authorities are also subject to loans-to-one borrower limits of $500,000 or below for most lenders and of varying amounts up to $3 million for ten senior lenders. These standards, as well as our collateral requirements, have not significantly changed in recent years.

In general, state banking laws restrict loans to a single borrower and related entities to no more than 25% of a bank's unimpaired capital and unimpaired surplus, plus an additional 10% if the loan is collateralized by certain readily marketable collateral. (Real estate is not included in the definition of "readily marketable collateral.”) As computed on the basis of the Bank's unimpaired capital and surplus at December 31, 2020, this limit was approximately $174.6 million. See "Government Supervision and Regulation." At December 31, 2020, the Bank was in compliance with the loans-to-one borrower limit. At December 31, 2020, the Bank's largest relationship for purposes of this limit, which consists of ten loans, totaled $68.4 million. This amount represents the total commitment for this relationship at December 31, 2020; the outstanding balance at that date was $62.6 million. The collateral for the loans consists of multiple warehouse, office, and other projects. Two of loans have credit lines that have not been disbursed. In addition, we obtained personal guarantees from the principal owner of the borrowing entities for each of these loans. All loans included in this relationship were current at December 31, 2020. In addition, at December 31, 2020, we had four other loan relationships that each exceeded $50 million. All loans included in these relationships were current at December 31, 2020. Our policy does not set a loans-to-one borrower limit that is below the legal limits described; however, we do recognize the need to limit credit risk to any one borrower or group of related borrowers upon consideration of various risk factors. Extensions of credit to borrowers whose past due loans were charged-off or whose loans are classified as substandard require special lending approval.

Great Southern is permitted under applicable regulations to originate or purchase loans and loan participations secured by real estate located in any part of the United States. In addition to the market areas where the Company has offices, the Bank has made or purchased loans, secured primarily by commercial real estate, in other states, primarily Alabama, Arizona, Florida, Louisiana, Michigan and Tennessee. At December 31, 2020, loans in these states comprised 2% or less each, respectively, of the total loan portfolio.

Loan Portfolio Composition

The following tables set forth information concerning the composition of the Bank’s loan portfolio in dollar amounts and in percentages (before deductions for loans in process, deferred fees and discounts and allowance for loan losses) as of the dates indicated. The tables are based on information prepared in accordance with generally accepted accounting principles and are qualified by reference to the Company’s Consolidated Financial Statements and the notes thereto contained in Item 8 of this report.

The loans acquired in the four FDIC-assisted transactions completed in 2009 through 2012, which were acquired at discounts and were previously covered by loss sharing agreements between the FDIC and the Bank, and the loans acquired in 2014 from the former Valley Bank, which were acquired at discounts and were never covered by a loss sharing agreement, are shown combined below in tables separate from the legacy Great Southern portfolio. All of these acquired loan portfolios were initially recorded at their fair values at the acquisition date and are recorded by the Company at their discounted value. The following tables reflect the loan balances excluding discounts.

(1)Total commercial real estate loans included industrial revenue bonds of $1.1 million, $1.2 million, $1.4 million, $2.2 million and $2.5 million at December 31, 2020, 2019, 2018, 2017 and 2016, respectively.
(2)At December 31, 2020, 2019, 2018 and 2017, none of these acquired loans were covered by an FDIC loss sharing agreement.

Based upon the collectability analyses performed at the time of the acquisitions, we expected certain levels of foreclosures and charge-offs, and actual results through December 31, 2020, related to the FDIC-assisted acquired portfolios, have been better than our expectations. As a result, cash flows expected to be received from the acquired loan pools have increased, resulting in adjustments that were made to the related accretable yield which are discussed in Note 4 of the accompanying audited financial statements, included in Item 8 of this Report.
