Item 1.01. Entry into a Material Definitive Agreement.

On April 10, 2026, Audax Private Credit Fund, LLC (the “Fund”), as borrower, entered into a senior secured credit facility (the “Facility”) pursuant to a Senior Secured Credit Agreement (the “Agreement”; capitalized terms used but not defined herein shall have the meanings specified in the Agreement), with JPMorgan Chase Bank, N.A., as administrative agent and as collateral agent, the lenders party thereto (the “Lenders”), and JPMorgan Chase Bank, N.A., PNC Bank, National Association and Pinnacle Bank, a Tennessee bank, d/b/a Synovus Bank, as lead arrangers and bookrunners. The Agreement is effective as of April 10, 2026.

The Fund may borrow amounts in U.S. dollars or certain other permitted currencies under the Facility. Advances under the Facility drawn in U.S. dollars will initially bear interest at a per annum rate equal to 1.75% or 1.875% plus the Adjusted Term SOFR Rate in the case of any Loan other than an ABR Loan, and 0.75% or 0.875% plus an Alternate Base Rate in the case of any ABR Loan, in each case, depending on the Fund’s rate option election and borrowing base (as of the most recently delivered borrowing base certificate delivered under the Agreement). Advances under the Facility drawn in currencies other than U.S. dollars will initially bear interest at a per annum rate equal to 1.75% or 1.875%, in each case depending on the Fund’s borrowing base (as of the most recently delivered borrowing base certificate delivered under the Agreement), plus any applicable credit spread adjustment, plus certain local rates consistent with market standards, each as specified in the Agreement. The Fund will also pay a fee of 0.375% per annum on daily undrawn amounts under the Facility.

The initial principal amount of the Facility is $275,000,000, subject to availability under the borrowing base, which is based on the Fund’s portfolio investments and other outstanding indebtedness, with an accordion provision to permit increases to the total facility amount up to $412,500,000, subject to the satisfaction of certain conditions. The Facility includes a $50,000,000 limit for swingline loans.

The Facility is guaranteed by certain subsidiaries of the Fund, and will be guaranteed by certain subsidiaries of the Fund that are formed or acquired by the Fund in the future (collectively, the “Guarantors”). Proceeds of the Facility may be used for general corporate purposes, including, without limitation, repaying outstanding indebtedness, making other distributions, contributions and investments, the acquisition and funding of portfolio investments, and such other uses as permitted under the Agreement.

The Facility is secured by a perfected first-priority interest in substantially all of the portfolio investments held by the Fund and each Guarantor, subject to certain exceptions.

The availability period of the revolving commitments under the Facility will terminate on April 10, 2030 (the “Commitment Termination Date”) and the Facility will mature on April 10, 2031 (the “Maturity Date”). During the period from the Commitment Termination Date to the Maturity Date, the Fund will be obligated to make mandatory prepayments under the Facility out of the proceeds of certain asset sales, other recovery events and equity and debt issuances.

The Agreement includes customary affirmative and negative covenants, including financial covenants requiring the Fund to maintain a minimum shareholders’ equity and asset coverage ratio, and certain limitations on the incurrence of additional indebtedness and liens, as well as usual and customary events of default for revolving credit facilities of this nature.

The description above is only a summary of the material provisions of the Agreement and is qualified in its entirety by reference to the full text of such agreement, which is filed as Exhibit 10.1 to this current report on Form 8-K and incorporated by reference herein.
