On October 16, 2025, Fidus Investment Corporation (the “Company”) entered into a credit and security agreement (the “Credit Agreement”) relating to a special purpose vehicle credit facility (the “SPV Credit Facility”) by and among FIC Funding, LLC (the “SPV”), as borrower, the Company, as servicer and equityholder, ING Capital LLC, as administrative agent (the “Administrative Agent”) and lead arranger, Western Alliance Trust Company, N.A., as custodian, collateral agent, and collateral administrator, and the lenders from time to time parties thereto. The SPV Credit Facility provides for $175 million of initial commitments, and has an accordion feature that allows for an increase of the total commitments to up to $250 million, subject to certain conditions (including the consent of the Administrative Agent). The SPV Credit Facility has a reinvestment period until October 16, 2029 and matures on October 16, 2030. The advances under the SPV Credit Facility bear interest, subject to the Company’s election, on a per annum basis equal to one-month Term SOFR plus 0.11448% and an applicable margin ranging from 2.500% to 2.675%. The SPV pays a commitment fee that varies depending on the size of the unused portion of the SPV Credit Facility: (1) if the utilized portion of the aggregate commitments as of the close of business on such day is less than 35% of the aggregate commitments (the “Minimum Utilization Amount”), the commitment fee will equal the sum of (a) the then applicable margin multiplied by (i) the Minimum Utilization Amount minus (ii) the aggregate outstanding principal balance of the advances on such day and (b) 0.50% multiplied by 65% of the commitments and (2) if the utilized portion of the aggregate commitments is greater than or equal to the Minimum Utilization Amount, the commitment fee will equal 0.50% multiplied by the unused amount of the commitments.

Borrowing under the SPV Credit Facility is subject to, among other things, a minimum borrowing base. The SPV Credit Facility is secured primarily by a pledge of 100% of the equity interest in the SPV held by the Company and the SPV’s assets, which consist of certain bank loans or securities. The SPV has made customary representations and warranties and is required to comply with various covenants, reporting requirements and other customary requirements for similar credit facilities.

The description above is only a summary of the material provisions of the SPV Credit Facility and is qualified in its entirety by reference to the full text of the Credit Agreement, which is filed as Exhibit 10.1 hereto and is incorporated herein by reference herein.

On October 16, 2025, the Company terminated in full (i) the amended and restated senior secured revolving credit agreement, dated as of April 24, 2019 (as amended from time to time, the “Revolving Credit Agreement”), by and among the Company, as borrower, the lenders party thereto, and ING Capital LLC, as administrative agent, arranger and bookrunner, and (ii) the amended and restated guarantee, pledge and security agreement, dated as of April 24, 2019 (as amended from time to time, the “Guarantee and Security Agreement”), by and among the Company, as borrower, the subsidiary guarantors party thereto, ING Capital LLC, as revolving administrative agent, each financing agent and designated indebtedness holder party thereto, and ING Capital LLC, as collateral agent. The Revolving Credit Agreement and the Guarantee and Security Agreement were terminated concurrent with the satisfaction of all obligations and liabilities of the Company to the lending parties thereunder, including, without limitation, payments of principal and interest, other fees, breakage costs and other amounts owing to the lending parties.

The information set forth under Item 1.01 is incorporated by reference into this Item 2.03.
