U.S. Revolving Credit Facility

On April 2, 2024 (the “Restatement Date”), the Company and certain subsidiaries of the Company entered into a Restatement Agreement (the "Restatement Agreement") with Bank of America, N.A. as administrative agent and collateral agent ("BofA"), and the several lenders from time to time party thereto (together with BofA, the "Lenders"), which amended and restated the Company’s Credit Agreement, dated as of March 28, 2020 (as previously amended by that certain Amendment No. 1 to Credit Agreement, dated as of February 6, 2023, and as otherwise amended, amended and restated, supplemented or otherwise modified prior to the Restatement Date (the “Credit Facility”) to extend the maturity date to April 2, 2029.

Pursuant to the Restatement Agreement, all of the $425.0 of revolving facility commitments under the Credit Agreement (the “Existing Revolving Facility Commitments”) were replaced with an equal amount of new revolving facility commitments (the “Replacement Revolving Facility Commitments”, collectively, with the Existing Revolving Facility Commitments, the “Revolving Credit Facility”) having substantially similar terms as the Existing Revolving Facility Commitments, except that the maturity date of the Replacement Revolving Facility Commitments will be the earlier of (i) April 2, 2029, and (ii) (a) March 2, 2028, if the aggregate outstanding amount of the Company’s 5.500% Senior Notes due 2028 is greater than $150.0 as of such date and (b) December 29, 2028, if the aggregate outstanding amount of the Company’s 4.125% Senior Notes due 2029 is greater than $150.0 of as such date, in each case, subject to certain exceptions.

Debt Covenants

The U.S. revolving credit facility discussed above (“Revolving Credit Facility”) governing our outstanding debt at September 30, 2025 contains certain customary representations and warranties, financial covenants, covenants restricting the Company’s ability to take certain actions, affirmative covenants and provisions relating to events of default. Under the terms of the Revolving Credit Facility, the ratio of the Company’s indebtedness to earnings before interest, taxes, depreciation and amortization (“EBITDA”), as defined in the agreement and detailed below, cannot be greater than 4.0 to 1.0, however, there is an exception for acquisition activity. In addition, under the Revolving Credit Facility, the ratio of the Company’s EBITDA, as defined in the credit agreement, to total interest expense must exceed 3.0 to 1.0. Under the Revolving Credit Facility, EBITDA is defined as net earnings, as adjusted to add-back interest expense, income taxes, depreciation and amortization, all of which are determined in accordance with GAAP. In addition, the credit agreement allows certain non-cash charges such as stock award amortization and asset write-offs including, but not limited to, impairment and accelerated depreciation, and operating expense reductions or synergies to be “added-back” in determining EBITDA for purposes of the indebtedness ratio. Total debt and interest expense are calculated in accordance with GAAP. If the Company fails to comply with these covenants or with other requirements of the Revolving Credit Facility, the lenders may have the right to accelerate the maturity of the debt. Acceleration under the Revolving Credit Facility would trigger cross-defaults on its other borrowings.

As of September 30, 2025, the Company was in compliance with the provisions and covenants associated with the Revolving Credit Facility.
