NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(unaudited)

(1) INTERIM FINANCIAL STATEMENTS

The interim financial statements for Ciena Corporation and its wholly owned subsidiaries (“Ciena”) included herein have been prepared by Ciena, without audit, pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”).

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States (“GAAP”) requires Ciena to make judgments, assumptions, and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and accompanying notes. Among other things, these estimates form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ materially from these estimates under different assumptions or conditions. To the extent that there are material differences between Ciena’s estimates and actual results, Ciena’s consolidated financial statements will be affected.

In the opinion of management, the financial statements included in this report reflect all normal recurring adjustments that Ciena considers necessary for the fair statement of the results of operations of Ciena for the interim periods covered and of the financial position of Ciena at the date of the interim balance sheets. Certain information and footnote disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to SEC rules and regulations. The Condensed Consolidated Balance Sheet as of November 2, 2024 was derived from audited financial statements but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena’s audited consolidated financial statements and the notes thereto included in Ciena’s Annual Report on Form 10-K for the fiscal year ended November 2, 2024 (the “2024 Annual Report”).

Ciena has a 52 or 53-week fiscal year, with quarters ending on the Saturday nearest to the last day of January, April, July, and October, respectively, of each year. Fiscal 2025 is a 52-week fiscal year. Fiscal 2024 was a 53-week fiscal year with the additional week occurring in the fourth quarter.

(2) SIGNIFICANT ACCOUNTING POLICIES

There have been no material changes to Ciena’s significant accounting policies, compared to the accounting policies described in Note 1, Ciena Corporation and Significant Accounting Policies and Estimates, in Notes to Consolidated Financial Statements in Item 8 of Part II of the 2024 Annual Report.

Accounting Standards - Not Yet Effective

In November 2023, the FASB issued ASU No. 2023-07 (“ASU 2023-07”), Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for Ciena’s fiscal 2025 Annual Report on Form 10-K on a retrospective basis. Ciena is currently evaluating the impact of this ASU on its segment disclosures.

In December 2023, the FASB issued ASU No. 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740): Improvement to Income Tax Disclosures, to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024. ASU 2023-09 allows for adoption using either a prospective or retrospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03 (“ASU 2024-03”), Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to improve financial reporting by requiring that public business entities disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027; however, early adoption is permitted. ASU 2024-03 allows for adoption using either a prospective or retrospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

In July 2025, the FASB issued ASU No. 2025-05 (“ASU 2025-05”), Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets, to introduce a practical expedient for all entities, which simplifies the calculation required for estimating credit losses and assumes that current conditions as of the balance sheet date do not change for the remaining life of the asset. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods; however, early adoption is permitted. ASU 2025-25 allows for adoption using a prospective method. Ciena is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures.

The related remeasurement adjustments were recorded in interest and other income, net, on the Condensed Consolidated Statements of Operations.

(6) INCOME TAXES

The effective tax rate for the third quarter of fiscal 2025 was higher than the effective tax rate for the third quarter of fiscal 2024, primarily due to the settlement of uncertain tax positions in the prior year.

The effective tax rate for the first nine months of fiscal 2025 was lower than the effective tax rate for the first nine months of fiscal 2024, primarily due to an income tax benefit for share-based compensation expense.

For the nine months ended August 2, 2025, the impact of the 15% global minimum tax, referred to as Pillar Two, was not material to Ciena’s consolidated financial statements.

On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law in the United States. The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions taking effect in fiscal 2025 and others to be implemented through fiscal 2027. The legislation will not have a material impact on Ciena’s consolidated financial statements in fiscal 2025.

Deductions from the reserve for excess and obsolete inventory relate primarily to sales and disposal activities.

(10) DERIVATIVE INSTRUMENTS

Foreign Currency Derivatives

Ciena conducts business globally in many currencies, and thus is exposed to foreign currency exchange rate changes. To limit this exposure, Ciena enters into foreign currency contracts. Ciena does not enter into such contracts for speculative purposes.

As of August 2, 2025 and November 2, 2024, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability in certain currencies for expenses principally related to research and development activities. The notional amount of these contracts was approximately $325.3 million and $257.0 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges.

As of August 2, 2025 and November 2, 2024, Ciena had forward contracts designated as net investment hedges to minimize the effect of foreign exchange rate movements on its net investments in foreign operations. The notional amount of these contracts was approximately $63.0 million and $65.4 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 36 months or less and have been designated as net investment hedges.

As of August 2, 2025 and November 2, 2024, Ciena had forward contracts in place to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. The notional amount of these contracts was approximately $138.5 million and $201.2 million as of August 2, 2025 and November 2, 2024, respectively. These foreign exchange contracts have maturities of 12 months or less and have not been designated as hedges for accounting purposes.

Interest Rate Derivatives

Ciena is exposed to floating rates of interest on its term loan borrowings (see Note 12 below) and has hedged such risk by entering into floating-to-fixed interest rate swap arrangements (“interest rate swaps”).

In April 2022, Ciena entered into forward starting interest rate swaps to fix the Secured Overnight Financing Rate (“SOFR”) for the first $350.0 million of its floating rate debt at 2.968% from September 2023 through September 2025 (“2025 interest rate swaps”). The total notional amount of the 2025 interest rate swaps was $350.0 million as of August 2, 2025 and November 2, 2024.

In January 2023, Ciena entered into interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.47% through January 2028. The total notional amount of these interest rate swaps was $350.0 million as of August 2, 2025 and November 2, 2024.

In December 2023, Ciena entered into forward starting interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.287% from September 2025 through December 2028 (“2028 forward starting interest rate swaps”). The total notional amount of the 2028 forward starting interest rate swaps effective September 2025 was $350.0 million as of August 2, 2025 and November 2, 2024.

Ciena expects the variable rate payments to be received under the terms of these interest rate swaps to offset exactly the forecasted variable rate payments on the equivalent notional amount of the Refinanced 2030 Term Loan (as defined in Note 12 below). These derivative contracts have been designated as cash flow hedges.

Other information regarding Ciena’s derivatives is immaterial for separate financial statement presentation. See Note 5 and Note 8 above.

Ciena added two new 10-year operating leases to its portfolio in the second quarter of fiscal 2025. The addition of these operating leases increased both operating right-of-use (“ROU”) assets and lease liabilities for fiscal 2025.

(12) 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):

Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate, through the maturity of the term loans. 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.

Outstanding Senior Notes Payable

2030 Notes

On January 18, 2022, Ciena entered into an indenture among Ciena, as issuer, certain domestic subsidiaries of Ciena, as guarantors, and U.S. Bank National Association, as trustee, pursuant to which Ciena issued $400.0 million in aggregate principal amount of 4.00% fixed-rate senior notes due 2030 (the “2030 Notes”).

The net carrying value of the 2030 Notes was comprised of the following as of the dates indicated (in thousands):

(14) EARNINGS PER SHARE CALCULATION

Basic net income per common share (“Basic EPS”) is computed using the weighted average number of common shares outstanding. Diluted net income per potential common share (“Diluted EPS”) is computed using the weighted average number of the following, in each case, to the extent that the effect is not anti-dilutive: (i) common shares outstanding; (ii) shares issuable upon vesting of stock unit awards; and (iii) shares issuable under Ciena’s employee stock purchase plan, using the treasury stock method.

The following table presents the calculation of Basic EPS and Diluted EPS for the periods indicated (in thousands, except per share amounts):

(15) STOCKHOLDERS’ EQUITY

Stock Repurchase Program

On October 2, 2024, Ciena announced that its Board of Directors authorized a three-year program to repurchase up to $1.0 billion of its common stock, commencing in fiscal 2025 and continuing through the end of fiscal 2027.

During the first nine months of fiscal 2025, Ciena repurchased approximately 3.3 million shares of its common stock for an aggregate purchase price of approximately $245.2 million, which equates to an average price of $75.02 per share. As of August 2, 2025, Ciena has an aggregate of $754.8 million authorized and remaining under its stock repurchase program. Ciena is required to allocate the purchase price for the shares of Ciena’s stock repurchased as a reduction of common stock and additional paid-in capital.

Stock Repurchases Related to Stock Unit Award Tax Withholdings

Ciena repurchases shares of its common stock to satisfy employee tax withholding obligations due on vesting of stock unit awards. The related purchase price of $60.0 million for the shares of Ciena’s stock repurchased during the first nine months of fiscal 2025 is reflected as a reduction to stockholders’ equity. Ciena is required to allocate the purchase price of the repurchased shares as a reduction of common stock and additional paid-in capital.

(18) COMMITMENTS AND CONTINGENCIES

Tax Contingencies

Ciena is subject to various tax contingencies arising in the ordinary course of business. Ciena does not expect that the ultimate settlement of these contingencies will have a material effect on its financial position or cash flows.

Litigation

Ciena is subject to various legal proceedings, claims, and other matters arising in the ordinary course of business, including those that relate to employment, commercial, tax, and other regulatory matters. Ciena is also subject to intellectual property related claims, including claims against third parties that may involve contractual indemnification obligations on the part of Ciena. Ciena does not expect that the ultimate costs to resolve such matters will have a material effect on its results of operations, financial position, or cash flows.

Purchase Obligations

Ciena has certain advanced commitments for supply of certain long lead time components. As of August 2, 2025, Ciena had $1.8 billion in outstanding purchase commitments to contract manufacturers and component suppliers for inventory. In certain instances, Ciena is permitted to cancel, reschedule or adjust these commitments. Consequently, only a portion of this amount relates to firm, non-cancelable and unconditional obligations.

(19) SUBSEQUENT EVENTS

Stock Repurchase Program

From the end of the third quarter of fiscal 2025 through August 29, 2025, Ciena repurchased 286,619 shares of its common stock for an aggregate purchase price of $26.4 million at an average price of $92.10 per share, inclusive of repurchases pending settlement under its current stock repurchase program. As of August 29, 2025, Ciena has an aggregate of $728.4 million of authorized funds remaining under this repurchase program.

Reallocation of Innovation Investment and Fiscal 2025 Restructuring Plan

On August 26, 2025, in order to align Ciena’s strategic investments with our highest-growth demand opportunities, its executive team determined to cease forward investment in certain broadband development initiatives, primarily 25G PON, within the routing and switching product line of the Network Platforms operating segment. Ciena intends to continue support and development of its 10G PON-based products.

Ciena’s executive team also approved a restructuring plan intended to deliver increased operating efficiencies and, as a result, commencing during the fourth quarter of fiscal 2025, Ciena is implementing a workforce reduction of approximately 4%

to 5% of its global headcount, which includes employees associated with the broadband development initiatives discussed above.

The estimated cash cost related to these actions is approximately $20.0 million and represents employee severance and related costs. As such, we expect an expense of approximately $20.0 million to be incurred in the fourth quarter of fiscal 2025. In addition, Ciena anticipates that its decision to cease future investment in 25G PON will result in a non-cash charge in the fourth quarter of fiscal 2025 related to the abandonment of its in-process R&D intangible asset, which has a carrying value of $89.1 million as of August 2, 2025. During the fourth quarter of fiscal 2025, Ciena will also evaluate the impact of these actions on other assets including, but not limited to, inventory and fixed assets.
