INTERNAL CONTROL RPT

REPORT OF INDEPENDENT

ACCOUNTING FIRM



To the Shareholders and
Board of Trustees of
Investment Managers Series Trust
Glendora, California 91740


In planning and performing our audit of
the financial statements of Riverbridge
Growth Fund (the "Fund"), a series of
Investment Managers Series Trust, as of
and for the year ended November 30,
2022, in accordance with the standards of
the Public Company Accounting
Oversight Board (United States), we
considered their 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 Fund's internal control over
financial reporting. Accordingly, we
express no such opinion.

The management of the Fund 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 generally accepted
accounting principles.  A company's
internal control over financial reporting
includes those policies and procedures that
(1) pertain to the maintenance of records
that, in reasonable detail, accurately and
fairly reflect the transactions and
dispositions of the assets of the company;
(2) provide reasonable assurance that
transactions are recorded as necessary to
permit preparation of financial statements
in accordance with generally accepted
accounting principles, and that receipts
and expenditures of the company are
being made only in accordance with
authorizations of management and
directors of the company; and (3) 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 deficiency in internal control over
financial reporting 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
material weakness is a deficiency, or
combination of deficiencies, in internal
control over financial reporting, such that
there is a reasonable possibility that a
material misstatement of the company's
annual or interim financial statements will
not be prevented or detected on a timely
basis.










Our consideration of the Fund's internal
control over financial reporting was for
the limited purpose described in the first
paragraph and would not necessarily
disclose all deficiencies in internal
control that might be material
weaknesses under standards established
by the Public Company Accounting
Oversight Board (United States).
However, we noted no deficiencies in the
Fund'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
November 30, 2022.

This report is intended solely for the
information and use of management,
Shareholders and Board of Trustees of
Investment Managers Series Trust and
the Securities and Exchange
Commission, and is not intended to be
and should not be used by anyone other
than these specified parties.
