REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Shareholders and Board of Trustees
Professionally Managed Portfolios
Milwaukee, Wisconsin
In planning and performing our audits of the financial statements of Boston Common ESG Impact Emerging Markets Fund, Boston Common ESG Impact
International Fund and Boston Common ESG Impact U.S. Equity Fund, each a series of Professionally Managed Portfolios (the “Trust”) as of and for the year ended September 30, 2022, in accordance with the standards of the Public Company Accounting
Oversight Board (United States), we considered its internal control over financial reporting, including control activities for safeguarding securities, as a basis for designing our auditing procedures for the purpose of expressing our opinion on the
financial statements and to comply with the requirements of Form N-CEN, but not for the purpose of expressing an opinion on the effectiveness of the Trust’s internal control over financial reporting. Accordingly, we express no such opinion.
The management of the Trust is responsible for establishing and maintaining effective internal control over financial reporting. In fulfilling this
responsibility, estimates and judgments by management are required to assess the expected benefits and related costs of controls. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding
the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Such internal control includes policies and
procedures that provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of a company’s assets that could have a material effect on the financial statements.
Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any
evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
A control deficiency exists when the design or operation of a control does not allow management or employees, in the normal course of performing
their assigned functions, to prevent or detect misstatements on a timely basis. A significant deficiency is a control deficiency, or combination of control deficiencies, that adversely affects the company’s ability to initiate, authorize, record,
process or report financial data reliably in accordance with accounting principles generally accepted in the United States of America such that there is more than a remote likelihood that a misstatement of the company’s annual or interim financial
statements that is more than inconsequential will not be prevented or detected. A material weakness is a significant deficiency, or combination of significant deficiencies, that results in more than a remote likelihood that a material misstatement of
the annual or interim financial statements will not be prevented or detected.

not necessarily disclose all deficiencies in internal control that might be significant deficiencies or material weaknesses under standards established by the Public Company Accounting Oversight Board (United States). However, we noted no
deficiencies in the Trust’s internal control over financial reporting and its operation, including controls for safeguarding securities, which we consider to be material weaknesses, as defined above, as of September 30, 2022.
