REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Trustees of
Horizon Funds

In planning and performing our audit of the financial
statements of Horizon Funds comprising Horizon Active
Asset Allocation Fund, Horizon Active Risk Assist Fund,
Horizon Active Income Fund, Horizon Active Dividend Fund,
Horizon Defined Risk Fund, Horizon Defensive Multi-Factor
Fund, and Horizon ESG Defensive Core Fund (the "Funds")
as of and for the period ended November 30, 2020, in
accordance with the standards of the Public Company
Accounting Oversight Board (United States), we considered
the Funds' internal control over financial reporting,
including controls over 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 Funds' internal
control over financial reporting.  Accordingly, we
express no such opinion.

The management of the Funds 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 fund'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 (GAAP).  A fund'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 fund; (2) provide
reasonable assurance that transactions are recorded
as necessary to permit preparation of financial
statements in accordance with GAAP, and that receipts
and expenditures of the fund are being made only in
accordance with authorizations of management and
trustees of the fund; and (3) provide reasonable
assurance regarding prevention or timely detection
of unauthorized acquisition, use or disposition of
a fund?s assets that could have a material effect
on the financial statements.

Because of its 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 Funds' annual or interim financial statements
will not be prevented or detected on a timely basis.

Our consideration of the Funds? 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 Funds' internal control over
financial reporting and its operation, including
controls over safeguarding securities, that we consider
to be a material weakness as defined above as of November 30, 2020.

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