State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Frontier Funds (the "Trust") has determined that is unable to file its Annual Report on Form 10-K for the year ended December 31, 2022 (the "Form 10-K") by the prescribed due date without unreasonable effort or expense because the Trust requires additional information from third parties relating to the Trust's underlying investments in order for it to complete the Trust's Form 10-K and to provide sufficient time for its independent registered public accountants, Spicer Jeffries LLP, to complete their review of the Trust's financial statements for the year ended December 31, 2022. In accordance with Rule 12b-25 of the Securities Exchange Act of 1934, as amended, the Trust expects to file its Form 10-K no later than the fifteenth calendar day following the prescribed due date.

The foregoing statement about the anticipated timing of the filing of the Form 10-K is a forward-looking statement within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based upon information presently available to the Trust and assumptions that it believes to be reasonable. Investors are cautioned not to place undue reliance upon forward looking statements in this notification of late filing. The Trust undertakes no obligation to revise or update these forward-looking statements to reflect events or circumstances after the date of this filing, except as required by law.
