HARMONIC INC. Debt Disclosure

NOTE 8: DEBT

Revolving and Term Facilities

In December 2023, the Company entered into a five-year Credit Agreement (the “Credit Agreement”), by and among the Company, certain subsidiaries of the Company from time to time party thereto, the lenders from time to time party thereto, and Citibank N.A., as administrative agent for the lenders. As amended in December 2024, the Credit Agreement provides for a secured revolving credit facility in an aggregate principal amount of up to $160.0 million (“the Revolving Facility”), with a $10.0 million sublimit for the issuance of letters of credit, and a secured delayed draw term loan facility in an aggregate principal amount of up to $40.0 million (the “Term Facility”). The Revolving Facility and the Term Facility both mature on December 21, 2028. The proceeds of the loans under the Revolving Facility may be used for general corporate purposes. The proceeds of the loans under the Term Facility were required to be used to repurchase, redeem, acquire or otherwise settle the 2024 Notes. In April 2024, the Company borrowed all $40.0 million under the Term Facility in connection with settling conversions of the 2024 Notes. The Credit Agreement also includes an uncommitted accordion feature whereby the Company may increase the Revolving Facility and/or establish one or more new term loan facilities by an aggregate amount not to exceed $100.0 million during the term of the Credit Agreement, subject to certain conditions, including lender consent. In December 2024, the Company amended the Credit Agreement, increasing the revolving credit commitments in an aggregate principal amount of up to $40.0 million. As a result of the additional commitments, the Credit Agreement now provides for loans in an aggregate principal amount of up to $200.0 million, consisting of a $160.0 million revolving credit facility and a $40.0 million term loan facility.

Loans under the Revolving Facility and Term Facility bear interest, at a floating rate per annum equal to an adjusted Term Secured Overnight Financing Rate (“SOFR”) (based on one-, three- or six-month interest periods), plus a SOFR premium fee of 0.1% and an applicable margin of between 2.00% to 2.75%, determined based on the Company’s consolidated net leverage ratio. Unused commitments under the Revolving Facility are subject to a quarterly fee ranging from 0.25% to 0.35%, determined based on the Company’s consolidated net leverage ratio.

The Credit Agreement contains customary affirmative and negative covenants. The Company is also required to maintain compliance with a maximum consolidated net leverage ratio and a minimum fixed charge coverage ratio, in each case, determined in accordance with the terms of the Credit Agreement. As of December 31, 2025, the Company was in compliance with the covenants under the Credit Agreement.

Repayment of the principal amount of the term loans began on December 31, 2024, in quarterly installments equal to 1.25% of the initial borrowing of $40.0 million under the Term Loan Facility, increasing to 1.875% beginning December 31, 2025, and to 2.50% beginning December 31, 2027. As of December 31, 2025, the Company had repaid $2.8 million of these installments, and $3.0 million were due in twelve months and therefore classified as current portion of long-term debt on the consolidated balance sheet. As of December 31, 2025, the Company had outstanding borrowings of $37.3 million under the Term Facility, $75.0 million under the Revolving Facility, $3.0 million of letters of credit issued, and $82.0 million of remaining capacity under the Revolving Facility. The carrying value of the borrowings under the Credit Agreement approximates their fair value because they bear interest at a market rate.

For the fiscal years ended December 31, 2025 and 2024, the Company incurred interest expenses of $6.3 million and $5.1 million, respectively, on these borrowings.

2.00% Convertible Senior Notes due 2024 (the “2024 Notes”)

In September 2019, the Company issued $115.5 million of the 2024 Notes pursuant to an indenture (the “2024 Notes Indenture”), dated September 13, 2019, by and between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee. The 2024 Notes would have matured on September 1, 2024, unless earlier repurchased by the Company, redeemed by the Company or converted pursuant to their terms.

In April 2024, the Company settled the conversion of the entire $115.5 million in aggregate principal amount of the 2024 Notes. In accordance with the provisions of the 2024 Notes Indenture, the Company settled such conversions of the 2024 Notes by paying and delivering, as applicable, a combination of $115.5 million in cash and 4.6 million shares of the Company’s common stock.
