Report of Independent Registered Public Accounting Firm
Plan Administrator, Plan Participants,
and Audit Committee
Southern Bank 401(k) Retirement Plan
Poplar Bluff, Missouri
Opinion on the Financial Statements
We have audited the accompanying statements of net assets available for benefits of Southern Bank
401(k) Retirement Plan (the Plan) as of June 30, 2021 and 2020, and the related statement of
changes in net assets available for benefits for the year ended June 30, 2021, and the related notes
(collectively referred to as the “financial statements”). In our opinion, the financial statements
referred to above present fairly, in all material respects, the net assets available for benefits of the
Plan as of June 30, 2021 and 2020, and the changes in net assets available for benefits for the year
ended June 30, 2021 in conformity with accounting principles generally accepted in the United
States of America.
Basis of Opinion
These financial statements are the responsibility of the Plan’s management. Our responsibility is to
express an opinion on these financial statements based on our audits.
We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (“PCAOB”) and are required to be independent with respect to the Plan in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require
that we plan and perform the audits to obtain reasonable assurance about whether the financial
statements are free of material misstatement, whether due to error or fraud. The Plan is not
required to have, nor were we engaged to perform, an audit of its internal control over financial
reporting. As part of our audits we are required to obtain an understanding of internal control over
financial reporting but not for the purpose of expressing an opinion on the effectiveness of the
Plan’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the
financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence regarding the amounts
and disclosures in the financial statements. Our audits also included evaluating the accounting
principles used and significant estimates made by management, as well as evaluating the overall
presentation of the financial statements. We believe that our audits provide a reasonable basis for
our opinion.
