2033 Senior Notes
On June 3, 2026, the Company issued $450 million in aggregate principal amount of 5.875% Senior Notes due 2033 (2033 Notes). Interest on the 2033 Notes is payable semi-annually in arrears at a rate of 5.875% per year. The 2033 Notes mature on June 15, 2033. The 2033 Notes are unsecured and unsubordinated obligations of the Company and equally ranked with all its existing and future senior unsecured debt. The 2033 Notes restrict the Company’s ability to incur certain liens, enter into sale leaseback transactions, guarantee certain indebtedness or consolidate with or merge into another entity or sell, transfer or lease all, or substantially all, of its assets.
The Company received proceeds of $443.1 million from the issuance of the 2033 Notes, which were net of $6.9 million of underwriting fees and other third-party expenses. These debt issuance costs were recorded as a reduction to the carrying value of the debt and will be amortized over the 7-year term of the 2033 Notes.
Prior to June 15, 2029, the Company has the option to redeem the 2033 Notes, as a whole or in part, at any time or from time to time, at redemption prices specified in the 2033 Notes. The 2033 Notes are subject to redemption upon the occurrence of a change in control repurchase event (as defined in the 2033 Notes) at a redemption price in cash equal to 101% of the aggregate principal amount of the Notes repurchased, plus any accrued and unpaid interest on the 2033 Notes repurchased.
2027 Senior Notes
On June 8, 2026, the Company exercised its right to redeem the entire outstanding $350 million in aggregate principal amount of its 5.875% Notes due 2027 (2027 Notes), and The Bank of New York Mellon, as trustee, issued a notice of redemption to registered holders of the 2027 Notes. The 2027 Notes were fully redeemed on July 8, 2026 using a portion of the proceeds from the sale of the Company's 2033 Notes. As of June 28, 2026, the outstanding balance of the 2027 Notes, net of unamortized debt issuance costs have been classified as current liabilities on the consolidated balance sheets. Refer to Note 17 – Subsequent Events for further discussion and detail on the redemption of the 2027 Notes.
Revolving Credit Facility
The Company's amended Asset Based Lending (ABL) Credit Facility, which is collateralized by the accounts receivable and inventory of the Company’s operations, consists of a $200 million term loan (Term Loan) and a $600 million revolving credit facility, which includes a letter of credit sub-facility of up to $200 million and a swing loan facility of up to $60 million. Through June 13, 2026 and as long as no default or event of default had occurred and was continuing, the Company had the ability to borrow an additional term loan of up to $100 million in total, using one or two draws (the Delayed-Draw Term Loan), which the Company did not exercise. The Term Loan bears interest at a rate of 2.0% above the adjusted Secured Overnight Financing Rate (SOFR) and can be prepaid in increments of $25 million if certain minimum liquidity conditions are satisfied. In addition, the Company has the right to request an increase of up to $300 million in the maximum amount available under the
revolving credit facility for the duration of the ABL. The ABL facility also provides the Company with the option of including certain machinery and equipment as additional collateral for purposes of determining availability under the facility. The ABL term runs through June of 2030.
The applicable interest rate for revolving credit borrowings under the ABL facility includes interest rate spreads based on available borrowing capacity that range between 1.25% and 1.75% for SOFR-based borrowings and between 0.25% and 0.75% for base rate borrowings. The ABL facility contains a financial covenant whereby the Company must maintain a fixed charge coverage ratio of not less than 1.00:1.00 after an event of default has occurred and is continuing or if the undrawn availability under the ABL revolving credit portion of the facility is less than the greater of (i) 10% of the then applicable maximum loan amount under the revolving credit portion of the ABL and the outstanding Term Loan balance, or (ii) $60.0 million. The Company was in compliance with the fixed charge coverage ratio as of June 28, 2026. Additionally, the Company must demonstrate minimum liquidity specified by the facility during the 90-day period immediately preceding the stated maturity date of its 4.875% Senior Notes due 2029, 7.25% Senior Notes due 2030 and 5.125% Senior Notes due 2031. Costs associated with entering into the June 2025 ABL amendment were $2.8 million, and are being amortized to interest expense over the extended term of the facility ending June 2030, along with $1.9 million of unamortized deferred costs previously recorded for the ABL. The ABL, as amended, also contains customary affirmative and negative covenants for credit facilities of this type, including limitations on the Company’s ability to incur additional indebtedness or liens or to enter into investments, mergers and acquisitions, dispositions of assets and transactions with affiliates, some of which are more restrictive at any time during the term of the ABL when the Company’s fixed charge coverage ratio is less than 1.00:1.00 and its undrawn availability under the revolving portion of the ABL is less than the greater of (a) $120 million or (b) 20% of the sum of the maximum loan amount under the revolving credit portion of the ABL and the outstanding Term Loan balance.
As of June 28, 2026, there were no outstanding borrowings under the revolving portion of the ABL facility, and $29.3 million was utilized to support the issuance of letters of credit. There were average revolving credit borrowings of $65.9 million and $64.0 million for the quarter and year-to-date periods June 28, 2026, respectively, bearing an average annual interest rate of 5.0% and 5.2%, respectively, under the ABL facility. There were no revolving credit borrowings under the ABL facility as of June 29, 2025. The Company also has foreign credit facilities, primarily in China, that total $75.4 million based on June 28, 2026 foreign exchange rates, $2.7 million of which was drawn as of June 28, 2026. There were no amounts drawn under foreign credit facilities as of December 28, 2025.
