SHORT-TERM AND LONG-TERM DEBT | SHORT-TERM AND LONG-TERM DEBT Outstanding Term Loan Payable Refinanced 2030 Term Loan Pursuant to a Credit Agreement, dated July 15, 2014, as amended (the “Credit Agreement”), by and among Ciena Corporation, the lenders party thereto and Bank of America, N.A., as administrative agent (the “Administrative Agent”), Ciena maintained a senior secured term loan with an outstanding aggregate principal amount, as of January 17, 2025, of approximately $1.16 billion and maturing on October 24, 2030 (the “2030 Term Loan”). On January 17, 2025, Ciena Corporation, as borrower, and Ciena Communications, Inc., Ciena Government Solutions, Inc., Ciena Communications International, LLC and Blue Planet Software, Inc., as guarantors, entered into a Refinancing Amendment to Credit Agreement with the lenders party thereto and the Administrative Agent (the “Amendment”), pursuant to which Ciena incurred a new single tranche of senior secured term loans in an aggregate principal amount of approximately $1.16 billion (the “Refinanced 2030 Term Loan”). The proceeds of the Refinanced 2030 Term Loan, together with cash on hand, were used to refinance in full the 2030 Term Loan, including accrued interest, and pay transaction fees and expenses. The Amendment amends the Credit Agreement and provides that the Refinanced 2030 Term Loan will, among other things: •mature on October 24, 2030; •amortize in equal quarterly installments in aggregate amounts equal to approximately 0.25% of the principal amount of the Refinanced 2030 Term Loan as of the Closing Date, with the balance payable at maturity; •be subject to mandatory prepayment upon the occurrence of certain specified events substantially similar to the 2030 Term Loan, including upon the occurrence of certain specified events such as asset sales, debt issuances, and receipt of annual Excess Cash Flow (as defined in the Credit Agreement); •bear interest, at Ciena’s election, at a per annum rate equal to (a) SOFR (subject to a floor of 0.00%) plus an applicable margin of 1.75%, or (b) a base rate (subject to a floor of 1.00%) plus an applicable margin of 0.75%; •be repayable at any time at Ciena’s election; and •except as described above or otherwise set forth in the Amendment, have substantially identical terms as the 2030 Term Loan. Except as amended by the Amendment, the remaining terms of the Credit Agreement remain in full force and effect. The net carrying value of the Ciena’s term loans were comprised of the following as of the date indicated (in thousands):
|  | August 2, 2025 |  | November 2, 2024
|  | Principal Balance |  | Unamortized Discount |  | Deferred Debt Issuance Costs |  | Net Carrying Value |  | Net Carrying Value

The amortization of deferred debt issuance costs for the term loans is included in interest expense and was approximately $0.7 million during both the first nine months of fiscal 2025 and fiscal 2024. As of August 2, 2025, the estimated fair value of the Refinanced 2030 Term Loan was $1.15 billion. Ciena’s term loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its term loan using a market approach based on observable inputs, such as current market transactions involving comparable securities.
