INTERIM FINANCIAL STATEMENTS	Jan. 28, 2023
Quarterly Financial Data [Abstract]
INTERIM FINANCIAL STATEMENTS	INTERIM FINANCIAL STATEMENTS The interim financial statements included herein for Ciena Corporation and its wholly owned subsidiaries (“Ciena”) 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 of America (“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 October 29, 2022 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 fiscal 2022 (the “2022 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 2023 and 2022 are 52-week fiscal years.

Newly Issued Accounting Standards - Not Yet Effective In October 2021, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08 (“ASU 2021-08”), Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers to improve the accounting for acquired revenue contracts with customers in a business combination to address recognition of an acquired contract liability and payment terms and their effect on subsequent revenue recognized by the acquirer. ASU 2021-08 is effective for annual periods beginning after December 15, 2022 on a prospective basis. Early adoption is permitted. Ciena is currently evaluating the impact of this ASU on its condensed consolidated financial statements and related disclosures.

Business Combination and Asset Acquisition [Abstract]

BUSINESS COMBINATIONS

Benu and Tibit Acquisitions

On November 17, 2022, Ciena acquired Benu, a portfolio of cloud-native software solutions, including a virtual Broadband Network Gateway ((v)BNG), that complements Ciena’s existing portfolio of broadband access solutions. On December 30, 2022, Ciena acquired Tibit, a provider and developer of PON-specific hardware and operating software that can be integrated into a carrier-grade Ethernet switch and will strengthen Ciena’s portfolio of next-generation PON solutions that support residential, enterprise, and mobility use cases. These businesses were acquired for an aggregate of approximately $291.7 million, of which $244.7 million was paid in cash and $47.0 million represents the fair value of Ciena’s previously held cost method equity investment in Tibit. The acquisition of Tibit triggered the remeasurement of Ciena’s previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its cost method equity investment of $26.5 million. Each of these transactions has been accounted for as the acquisition of a business.

Ciena incurred approximately $2.5 million in acquisition-related costs associated with these acquisitions. These costs and expenses primarily include fees associated with financial, legal, and accounting advisors and employment-related costs. These costs were recorded in acquisition and integration costs on the Condensed Consolidated Statement of Operations.

The following table summarizes the final purchase price allocation related to the acquisitions based on the estimated fair value of the acquired assets and assumed liabilities (in thousands):


	Amount
Cash and cash equivalents	$	14,634
Accounts receivable, net	443
Inventories, net	1,406
Prepaid expenses and other	810
Equipment, furniture and fixtures	1,090
Goodwill	117,997
Developed technology	75,400
In-process technology	89,100
Customer relationships and contracts	18,400
Order backlog	2,480
Deferred tax asset, net	(27,782)
Accounts payable	(420)
Accrued liabilities and other short-term obligations	(874)
Deferred revenue	(851)
Other long-term obligations	(144)
Total purchase consideration	$	291,689

Developed technology represents purchased technology that has reached technological feasibility and for which the acquired companies had substantially completed development as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Developed technology is amortized on a straight-line basis over its estimated useful life of five years.

In-process technology represents purchased technology that had not reached technological feasibility as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the in-process technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Upon completion of the in-process technology, it will be amortized on a straight line basis over its estimated useful life, which will be determined on that date.

Customer relationships and contracts represent agreements with existing Tibit customers and have an estimated useful life of three years. Order backlog is amortized over the fulfillment period.

The goodwill generated from these acquisitions is primarily related to expected economic synergies. The total goodwill amount was recorded in the Networking Platforms segment. The goodwill is not deductible for income tax purposes.

Pro forma disclosures have not been included due to immateriality. The amounts of revenue and earnings for these acquisitions since the acquisition dates, which are included on the Condensed Consolidated Statement of Operations for the reporting period are immaterial.

During the first quarter of fiscal 2023, the acquisition of Tibit triggered the remeasurement of Ciena’s previously held investment in Tibit to fair value, which resulted in Ciena recognizing a gain on its cost method equity investment of $26.5 million. See Note 4 above.

Ciena Corporation, as the U.S. parent entity, uses the U.S. Dollar as its functional currency; however, some of its foreign branch offices and subsidiaries use local currencies as their functional currencies. Ciena recorded $1.9 million in foreign currency exchange rate losses for the first three months of fiscal 2023 and during the first three months of fiscal 2022, Ciena recorded $4.8 million in foreign currency exchange rate gains, both as a result of monetary assets and liabilities that were transacted in a currency other than Ciena’s functional currency. The related remeasurement adjustments were recorded in interest and other income, net, on the Condensed Consolidated Statements of Operations. From time to time, Ciena uses foreign currency forwards to hedge this type of balance sheet exposure. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is reported in interest and other income, net, on the Condensed Consolidated Statements of Operations. During the first three months of fiscal 2023, Ciena recorded losses of $1.8 million and during the first three months of fiscal 2022, Ciena recorded losses of $4.3 million from non-hedge designated foreign currency forward contracts.

Inventory Disclosure [Abstract]

INVENTORIES

As of the dates indicated, inventories are comprised of the following (in thousands):


	January 28, 2023		October 29, 2022
Raw materials	$	846,564	$	664,916
Work-in-process	18,422		18,232
Finished goods	300,684		258,584

Reserve for inventory excess and obsolescence	(38,900)		(36,086)
Inventories, net	$	1,178,089	$	946,730

The increase in raw materials inventory is related to the steps Ciena is taking to mitigate the impact of current supply chain constraints in the context of the global market shortage of semiconductor components. Ciena writes down its inventory for estimated obsolescence or unmarketable inventory by an amount equal to the difference between the cost of inventory and the estimated net realizable value based on assumptions about future demand, which are affected by changes in Ciena’s strategic direction, discontinuance of a product or introduction of newer versions of products, declines in the sales of or forecasted demand for certain products, and general market conditions. During the first three months of fiscal 2023, Ciena recorded a provision for inventory excess and obsolescence of $5.5 million, primarily related to a decrease in the forecasted demand for certain Networking Platforms products. Deductions from the provision for excess and obsolete inventory relate primarily to disposal activities.

DERIVATIVE INSTRUMENTS	3 Months Ended
DERIVATIVE INSTRUMENTS	Jan. 28, 2023
Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS Foreign Currency Derivatives Ciena conducts business globally in numerous currencies, and thus is exposed to adverse 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 January 28, 2023 and October 29, 2022, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability in certain currencies that is principally related to research and development activities. The notional amount of these contracts was approximately $265.6 million and $272.2 million as of January 28, 2023 and October 29, 2022, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges. As of January 28, 2023 and October 29, 2022, Ciena had forward contracts 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 $150.0 million and $108.0 million as of January 28, 2023 and October 29, 2022, 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 16 below) and has hedged such risk by entering into floating-to-fixed interest rate swap arrangements. Prior to amending the 2025 Term Loan (as defined in Note 16 below) to replace LIBOR with the Secured Overnight Financing Rate (“SOFR”) (see Note 16 below), Ciena was exposed to floating rates of LIBOR interest on its 2025 Term Loan borrowings. Ciena hedged this risk by entering into floating-to-fixed interest rate swap arrangements (“interest rate swaps”). The interest rate swaps fix the LIBOR rate for $350.0 million of the 2025 Term Loan at 2.957% through September 2023. In January 2023, Ciena entered into a LIBOR to SOFR basis swap (“basis swap”) to hedge its exposure to SOFR rate. The basis swap offsets the LIBOR exposure risk of the interest rate swaps and effectively fixes the SOFR rate for $350.0 million of the 2025 Term Loan at 2.883% through September 2023. The total notional amount of these swaps in effect was $350.0 million as of January 28, 2023 and October 29, 2022. In April 2022, Ciena entered into floating to fixed forward starting interest rate swap arrangements (“forward starting swaps”). The forward starting swaps fix the SOFR for $350.0 million of the 2025 Term Loan at 2.968% from September 2023 through the 2025 Term Loan maturity. The total notional amount of forward starting swaps effective September 2023 was $350 million as of January 28, 2023. In January 2023, Ciena entered into floating-to-fixed interest rate swap arrangements (“2028 interest rate swaps”). The 2028 interest rate swaps fix the SOFR rate of approximately $350.0 million of the principal amount of the 2030 Term Loan (as defined in Note 16 below) at 3.47% through January 2028. The total notional amount of these interest rate swaps in effect as of January 28, 2023 was $350.0 million. Ciena expects the variable rate payments to be received under the terms of the interest rate swaps, basis swap, forward starting swaps, and 2028 interest rate swaps to offset exactly the forecasted variable rate payments on the equivalent notional amounts of the 2025 Term Loan and 2030 Term Loan. 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 6 and Note 9 above.

SHORT-TERM AND LONG-TERM DEBT

Debt Disclosure [Abstract]

SHORT-TERM AND LONG-TERM DEBT

Outstanding Term Loans Payable

2025 Term Loan

On January 23, 2020, Ciena entered into a Refinancing Amendment to Credit Agreement pursuant to which Ciena refinanced the entire outstanding amount of its then existing senior secured term loan and incurred a new senior secured term loan in an aggregate principal amount of $693.0 million and maturing on September 28, 2025 (the “2025 Term Loan”).

On January 19, 2023, in connection with the Incremental Agreement (as defined below) to the Credit Agreement (as defined below), the Credit Agreement was amended to replace LIBOR with SOFR for the 2025 Term Loan in response to pending impact of Accounting Standards Codification 848 Reference Rate Reform.

The net carrying value of the 2025 Term Loan was comprised of the following as of the dates indicated (in thousands):


	January 28, 2023								October 29, 2022
	Principal Balance		Unamortized Discount		Deferred Debt Issuance Costs		Net Carrying Value		Net Carrying Value
2025 Term Loan	$	673,942	$	(847)	$	(1,586)	$	671,509	$	673,010

Deferred debt issuance costs that were deducted from the carrying amounts of the 2025 Term Loan totaled $1.6 million as of January 28, 2023 and $1.7 million at October 29, 2022. 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 2025 Term Loan. The amortization of deferred debt issuance costs for the 2025 Term Loan is included in interest expense, and was $0.2 million during the first three months of each of fiscal 2023 and fiscal 2022. The carrying value of the 2025 Term Loan listed above is also net of any unamortized debt discounts.

As of January 28, 2023, the estimated fair value of the 2025 Term Loan was $670.6 million. Ciena’s 2025 Term Loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2025 Term Loan using a market approach based on observable inputs, such as current market transactions involving comparable securities.

2030 Term Loan

On January 19, 2023, Ciena entered into an Incremental Joinder and Amendment Agreement (the “Incremental Agreement”) to its Credit Agreement, dated July 15, 2014, as amended (the “Credit Agreement”), by and among Ciena, the lenders party thereto and Bank of America, N.A., as administrative agent, pursuant to which Ciena incurred a new tranche of senior secured term loans in an aggregate principal amount of $500.0 million and maturing on January 19, 2030 (the “2030 Term Loan”). Net of original issue discount and debt issuance costs, the $493.5 million in proceeds from the 2030 Term Loan are intended to be used for general corporate purposes.

The Incremental Agreement amends the Credit Agreement and provides that the 2030 Term Loan will, among other things:

•mature on January 19, 2030;

•amortize in equal quarterly installments in aggregate amounts equal to 0.25% of the principal amount of the 2030 Term Loan as of January 19, 2023, or $1.25 million, with the balance payable at maturity;

•be subject to mandatory prepayment on the same basis as the 2025 Term Loan, including on 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 2.50%, or (b) a base rate (subject to a floor of 1.00%) plus an applicable margin of 1.50%; and

•be repayable at any time at Ciena’s election, provided that repayment of the 2030 Term Loan with proceeds of certain indebtedness prior to July 19, 2023 will require a prepayment premium of 1.00% of the aggregate principal amount of such prepayment.

Except as amended by the Incremental Agreement, the remaining terms of the Credit Agreement remain in full force and effect.

The net carrying value of the 2030 Term Loan was comprised of the following for the periods indicated (in thousands):


	January 28, 2023
	Principal Balance		Unamortized Discount		Deferred Debt Issuance Costs		Net Carrying Value
2030 Term Loan	$	500,000	$	(2,491)	$	(4,810)	$	492,699

Deferred debt issuance costs that were deducted from the carrying amounts of the 2030 Term Loan totaled $4.8 million as of January 28, 2023. 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 2030 Term Loan. The amortization of deferred debt issuance costs for the 2030 Term Loan is included in interest expense and was minimal during the first three months of fiscal 2023. The carrying value of the 2030 Term Loan listed above is also net of any unamortized debt discounts.

As of January 28, 2023, the estimated fair value of the 2030 Term Loan was $499.4 million. Ciena’s 2030 Term Loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2030 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% 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):


	January 28, 2023						October 29, 2022
	Principal Balance		Deferred Debt Issuance Costs		Net Carrying Value		Net Carrying Value
2030 Senior Notes 4.00% fixed-rate	$	400,000	$	(4,783)	$	395,217	$	395,045

Deferred debt issuance costs that were deducted from the carrying amount of the 2030 Notes totaled $4.8 million as of January 28, 2023 and $5.0 million as of October 29, 2022. 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 2030 Notes. The amortization of deferred debt issuance costs for the 2030 Notes is included in interest expense, and was $0.2 million during the first three months of fiscal 2023 and was minimal during the first three months of fiscal 2022.

As of January 28, 2023, the estimated fair value of the 2030 Notes was $351.0 million. The 2030 Notes are categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2030 Notes using a market approach based on observable inputs, such as current market transactions involving comparable securities.

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 and upon exercise of outstanding stock options, using the treasury stock method.

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


	Quarter Ended

Equity [Abstract]
STOCKHOLDERS’ EQUITY	STOCKHOLDERS’ EQUITY Stock Repurchase Program On December 9, 2021, Ciena announced that its Board of Directors authorized a program to repurchase up to $1.0 billion of its common stock. During the first three months of fiscal 2023, Ciena did not repurchase any additional shares of its common stock. As of January 28, 2023, Ciena has repurchased an aggregate of 8.4 million shares for an aggregate purchase price of $500.0 million at an average price of $59.28 per share and has an aggregate of $500.0 million of authorized funds remaining under its stock repurchase program. The purchase price for the shares of Ciena’s stock repurchased is reflected 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 $13.0 million for the shares of Ciena’s stock repurchased during the first three months of fiscal 2023 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.

- Definition

Share-based compensation expense capitalized in inventory, net	38		11
Total share-based compensation expense	$	30,512	$	24,297

As of January 28, 2023, total unrecognized share-based compensation expense was approximately $292.6 million, which relates to unvested stock unit awards and is expected to be recognized over a weighted-average period of 1.6 years.

Stock Unit Awards

Beginning in December 2022, Ciena introduced a benefit, under which, upon completion of ten years of service and reaching age 60, executive officers who are residents of the United States, United Kingdom, or Canada and who provide 12 months’ notice of their retirement will receive continued vesting of all of their granted but unvested restricted stock unit (“RSU”) awards and a pro-rated amount of their performance stock unit awards and market stock unit awards. Other employees in these countries will be subject to the same eligibility and notice requirements, but will receive acceleration of their granted but unvested RSU awards upon retirement. This program accelerates the recognition of share-based compensation expense.
