Report of Independent Public Accountant

To the Board of Trustees of

Advisors Preferred Trust

We have examined management’s assertion, included in the accompanying Management Statement Regarding Compliance With Certain Provisions of the Investment Company Act of 1940, that Spectrum Low Volatility Fund, Spectrum Active Advantage Fund, and Spectrum Unconstrained Fund (the “Funds”), each a series of Advisors Preferred Trust, complied with the requirements of subsections (b)(1) and (b)(6) of Rule 17f-1 under the Investment Company Act of 1940 (the “Act”) (the “specified requirements”) as of March 31, 2026. The Funds’ management is responsible for its assertion. Our responsibility is to express an opinion on management’s assertion about the Funds’ compliance with the specified requirements based on our examination.

Our examination was conducted in accordance with attestation standards established by the AICPA. Those standards require that we plan and perform the examination to obtain reasonable assurance about whether management’s assertion about compliance with the specified requirements is fairly stated, in all material respects. An examination involves performing procedures to obtain evidence about whether management’s assertion is fairly stated in all material respects. The nature, timing, and extent of the procedures selected depend on our judgment, including an assessment of the risks of material misstatement of management’s assertion, whether due to fraud or error. We believe that the evidence we obtained is sufficient and appropriate to provide a reasonable basis for our opinion.

We are required to be independent and to meet our other ethical responsibilities in accordance with relevant ethical requirements relating to the engagement.

Included among our procedures were the following tests performed as of March 31, 2026, and with respect to agreement of security purchases and sales, for the period from September 30, 2025 (the date of our last examination), through March 31, 2026:

Our examination does not provide a legal determination on the Funds’ compliance with specified requirements.

In our opinion, management’s assertion that Spectrum Low Volatility Fund, Spectrum Active Advantage Fund, and Spectrum Unconstrained Fund complied with the requirements of subsections (b)(1) and

(b)(6) of Rule 17f-1 of the Investment Company Act of 1940 as of March 31, 2026, with respect to securities reflected in the investment account of the Funds is fairly stated, in all material respects.
