Term Loan B
On October 16, 2025, concurrent with the closing of the acquisition of Spirent’s HSE and CE business, the Company entered into a $600.0 million senior secured term loan credit agreement (Term Loan Credit Agreement) with Wells Fargo Bank, National Association (Wells Fargo), as administrative agent, and other lenders. The term loans, which mature on October 16, 2032, are secured by substantially all of the assets of the Company and those of its domestic subsidiaries. The proceeds from the term loans were used to finance a portion of the acquisition, acquisition related expenses and for general corporate purposes. In connection with the issuance of the term loans, the Company incurred $15.2 million of issuance costs. The debt issuance costs were capitalized in Long-term debt on the Consolidated Balance Sheets and were amortized to interest expense using the straight-line method except for the unamortized debt issuance costs derecognized as part of the extinguishments.
During fiscal 2026, the Company voluntarily prepaid the entire $600.0 million outstanding principal balance under the Term Loan Credit Agreement. The prepayments were accounted for as extinguishments, with the carrying amount of the debt prepaid, including the unamortized debt issuance costs, derecognized, and any difference between the reacquisition price and the carrying amount recognized as a loss on debt extinguishment. The total loss from the prepayments was $14.2 million recorded as Loss on debt extinguishment in the Consolidated Statements of Operations.
0.625% Senior Convertible Notes (2031 Notes)
On August 20, 2025, the Company issued $250.0 million aggregate principal amount of 0.625% Senior Convertible Notes due 2031 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company issued $100.9 million aggregate principal amount of the 2031 Notes to certain holders of the 1.625% Senior Convertible Notes (2026 Notes) in exchange for $97.5 million principal amount of the 2026 Notes (the 2025 Exchange Transaction) and issued and sold $149.1 million aggregate principal amount of the 2031 Notes in a private placement to accredited institutional buyers (the 2025 Subscription Transactions).
The 2025 Exchange Transaction was accounted for as an extinguishment which resulted in the write-off of unamortized debt discount and issuance costs of $1.1 million on the extinguished notes. Accrued interest of $0.7 million on the 2026 Notes was included in the exchange for the 2031 Notes. The total loss from the exchange was $3.8 million recorded as Loss on debt extinguishment in the Consolidated Statements of Operations.
Concurrent with the transactions discussed above, the Company repurchased and subsequently retired 2.7 million shares of its common stock for $30.0 million under the repurchase plan authorized in September 2022.
In connection with the issuance of the 2031 Notes, the Company incurred $6.1 million of issuance costs. The debt issuance costs were capitalized and will be amortized to interest expense using the straight-line method until maturity.
The 2031 Notes are an unsecured obligation of the Company and bear interest at an annual rate of 0.625%, payable semi-annually in arrears on March 1 and September 1 of each year, beginning March 1, 2026. The 2031 Notes will mature on March 1, 2031 unless earlier converted, redeemed or repurchased.
The 2031 Notes may be converted under certain circumstances, based on an initial conversion rate of 72.5295 shares (equivalent to an initial conversion price of approximately $13.79 per share) at the option of the holders into cash up to the principal amount, with the remaining amount converted into cash, shares of the Company’s common stock, or a combination of cash and shares of the Company’s common stock at the Company’s election. The initial conversion price represents a 25.0% premium to the closing price of the Company’s common stock on the pricing date, August 13, 2025, which will be subject to customary anti-dilution adjustments.
During the first quarter of fiscal 2027, the closing price of the Company’s common stock exceeded 130% of the applicable conversion price of the 2031 Notes, on at least 20 of the last 30 consecutive trading days of the calendar quarter, causing the 2031 Notes to be convertible by their holders for the period October 1, 2026 to December 31, 2026. As a result, the $245.1 million carrying value of the 2031 Notes has been classified as short-term debt.
As of October 3, 2026, the expected remaining term of the 2031 Notes is 4.4 years.
1.625% Senior Convertible Notes (2026 Notes)
On March 6, 2023, the Company issued $250.0 million aggregate principal amount of 1.625% Senior Convertible Notes due 2026 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. The Company issued $132.0 million aggregate principal amount of the 2026 Notes to certain holders of the 1.00% Senior Convertible Notes due 2024 (2024 Notes) in exchange for $127.5 million principal amount of the 2024 Notes (the 2023 Exchange Transaction) and issued and sold $118.0 million aggregate principal amount of the 2026 Notes in a private placement to accredited institutional buyers (the 2023 Subscription Transactions).
The 2023 Exchange Transaction was accounted for as a modification. The $127.5 million principal of the 2024 Notes was reduced by $10.1 million, with offsetting increase to additional paid-in capital, to account for the increase in the fair value of the embedded conversion option in the modification. The increase in principal and coupon interest, along with the increased option value, totaled $14.6 million and is a direct reduction from the carrying amount of the debt on the Consolidated Balance Sheets. This amount has been accreted as an adjustment to interest expense on a straight-line basis up to the full face value of the 2026 Notes through maturity on March 15, 2026.
The proceeds of the 2023 Subscription Transactions amounted to $113.8 million after issuance costs of $4.2 million. The exchange resulted in $2.2 million of the issuance costs recorded as Loss on convertible note modification in the Consolidated Statements of Operations. The remaining issuance costs of $2.0 million, as well as $0.3 million of unamortized costs carried over from the 2024 Notes at the exchange date were capitalized within Long-term debt (as a contra-balance) on the Consolidated Balance Sheets and were amortized to interest expense using the straight-line method until maturity on March 15, 2026.
On August 20, 2025, as part of the 2025 Exchange Transaction, the Company exchanged $97.5 million aggregate principal amount of the 2026 Notes for $100.9 million aggregate principal amount of the 2031 Notes.
On December 15, 2025, the Company entered into separate privately-negotiated agreements with certain holders of the 2026 Notes. On December 22, 2025, the Company settled $103.5 million principal amount of 2026 Notes in exchange for an aggregate of 7.9 million shares of its common stock, par value $0.001 per share. Accrued interest was paid in cash. The transaction was accounted for as a debt extinguishment. The exchange did not qualify as an induced conversion. The Company recorded a Loss on debt extinguishment of $38.7 million in the Company’s Consolidated Statements of Operations, representing the excess of the fair value of the shares issued over the carrying amount of the notes extinguished and transaction costs associated with the settlement.
On March 15, 2026, the outstanding $49.0 million principal amount of the 2026 Notes matured. Nearly all holders of the 2026 Notes chose to convert and the settlement of the conversion resulted in a cash payment of $49.4 million, including $49.0 million in principal and $0.4 million in accrued interest, and the issuance of 1.8 million shares of its common stock for conversion value above par.
3.75% Senior Notes (2029 Notes)
On September 29, 2021, the Company issued $400.0 million aggregate principal amount of 3.75% Senior Notes due 2029 in a private offering to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended. In connection with the issuance of the 2029 Notes, the Company incurred $7.0 million of issuance costs. The debt issuance costs were capitalized and will be amortized to interest expense using the straight-line method until maturity. The 2029 Notes are an unsecured obligation of the Company and bear annual interest of 3.75%, payable semi-annually in arrears on April 1 and October 1 of each year, beginning April 1, 2022. The 2029 Notes will mature on October 1, 2029 unless earlier redeemed or repurchased. As of October 3, 2026, the expected remaining term of the 2029 Notes is 3.0 years.
Senior Secured Asset-Based Revolving Credit Facility
On December 30, 2021, we entered into a credit agreement (the Credit Agreement) with Wells Fargo as administrative agent, and other lender related parties. On October 16, 2025, the Company entered into an agreement with Wells Fargo to amend and extend the Credit Agreement. The Credit Agreement, as amended, provides for a senior secured asset-based revolving credit facility in a maximum aggregate amount of $200 million and matures on October 16, 2030. The Credit Agreement also provides that, under certain circumstances, the Company may increase the aggregate amount of revolving commitments thereunder by an aggregate amount of up to $100 million so long as certain conditions are met. The proceeds from the credit facility established under the Credit Agreement will be used for working capital and other general corporate purposes. The obligations under the Credit Agreement are secured by substantially all of the assets of the Company and those of its subsidiaries that are borrowers and guarantors under the Credit Agreement.
Amounts outstanding under the Credit Agreement accrue interest as follows: (i) if the amounts outstanding are denominated in U.S. Dollars, at a per annum rate equal to either, at the Company’s election, SOFR plus a margin of 1.50% to 2.00% per annum, or a specified base rate plus a margin of 0.50% to 1.00%, in each case, depending on the average excess availability under the facility, (ii) if the amounts outstanding are denominated in Sterling, at a per annum rate equal to the Sterling Overnight Interbank Average Rate (SONIA) plus a margin of 1.50% to 2.00%, depending on the average excess availability under the facility, (iii) if the amounts outstanding are denominated in Euros, at a per annum rate equal to the Euro Interbank Offered Rate plus a margin of 1.50% to 2.00%, depending on the average excess availability under the facility, or (iv) if the amounts outstanding are denominated in Canadian Dollars, at a per annum rate equal to either, at the Company’s election, the adjusted Term Canadian Overnight Repo Rate Average (CORRA) plus a margin of 1.50% to 2.00%, or a specified base rate plus a margin of 0.50% to 1.00%, in each case, depending on the average excess availability under the facility.
The covenants of the Credit Agreement include customary restrictive covenants that, among other things, restrict the Company’s ability to incur additional indebtedness, grant liens and make certain acquisitions, investments, asset dispositions and restricted payments. In addition, the Credit Agreement contains certain financial covenants that require the Company to maintain a fixed charge coverage ratio of at least 1.00 to 1.00 if excess availability under the facility is less than the greater of 10% of the lesser of maximum revolver amount and borrowing base and $13.3 million.
As of October 3, 2026, we had no borrowings under this facility and our available borrowing capacity was approximately $182.3 million, net of outstanding standby letters of credit of $3.8 million.
