Item 1.01.  Entry into a Material Definitive Agreement.

On July 29, 2025, FormFactor, Inc.

The Credit Agreement provides for a revolving credit facility in an aggregate principal amount of up to $150,000,000 (the “Facility”) with an option to draw additional Incremental Term Loans in $25,000,000 increments. The Facility has a maturity date of July 29, 2030.

The Facility may be used for working capital and other general corporate purposes, subject to the terms and conditions set forth in the Credit Agreement. Borrowings under the Facility will bear interest at a fluctuating rate per annum equal to, at FormFactor’s option, (i) the forward-looking Secured Overnight Financing Rate term rate (“Term SOFR” and such borrowings, “Term SOFR Loans”), (ii) a base rate set forth in the Credit Agreement, or (iii) a combination thereof, plus, in each case, an applicable margin calculated based on FormFactor’s leverage ratio. Voluntary prepayments are permissible without penalty, subject to certain conditions pertaining to minimum notice and minimum prepayment and reduction amounts as described in the Term Loan Agreement.

The Credit Agreement contains various customary representations and warranties and affirmative and negative covenants, as more fully described in the Credit Agreement, and FormFactor is required to maintain certain financial covenants, including leverage ratio and interest coverage ratio. The Credit Agreement also contains various customary events of default (subject to grace periods, as applicable) including, among others: nonpayment of principal, interest or fees; breach of covenant; payment default on, or acceleration under, certain other material indebtedness; inaccuracy of the representations or warranties in any material respect; bankruptcy or insolvency; inability to pay debts; certain unsatisfied judgments; and the occurrence of a change of control.

The foregoing description of the Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Credit Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.
