CIENA CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(unaudited)
(1) 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.
(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 2022 Annual Report.
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.

Contract Balances
The following table provides information about receivables, contract assets and contract liabilities (deferred revenue) from contracts with customers (in thousands):

|  | Balance at April 29, 2023 |  | Balance at October 29, 2022
Accounts receivable, net |  | $ | 1,036,688 |  |  | $ | 920,772 |
Contract assets for unbilled accounts receivable, net |  | $ | 180,020 |  |  | $ | 156,039 |
Deferred revenue |  | $ | 270,625 |  |  | $ | 200,235 |

Ciena’s contract assets represent unbilled accounts receivable, net where transfer of a product or service has occurred but invoicing is conditional upon completion of future performance obligations. These amounts are primarily related to installation and deployment and professional services arrangements where transfer of control has occurred, but Ciena has not yet invoiced the customer. Contract assets are included in prepaid expenses and other in the Condensed Consolidated Balance Sheets. See Note 11 below.
Contract liabilities consist of deferred revenue and represent advanced payments against non-cancelable customer orders received prior to revenue recognition. Ciena recognized approximately $100.1 million and $82.0 million of revenue during the first six months of fiscal 2023 and 2022, respectively, that was included in the deferred revenue balance as of October 29, 2022 and October 30, 2021, respectively. Revenue recognized due to changes in transaction price from performance obligations satisfied or partially satisfied in previous periods was immaterial during the six months ended April 29, 2023 and April 30, 2022.
12

Capitalized Contract Acquisition Costs
Capitalized contract acquisition costs consist of deferred sales commissions, and were $36.6 million and $39.7 million as of April 29, 2023 and October 29, 2022, respectively. Capitalized contract acquisition costs were included in (i) prepaid expenses and other and (ii) other long-term assets. The amortization expense associated with these costs was $16.2 million and $14.1 million during the first six months of fiscal 2023 and 2022, respectively, and was included in selling and marketing expense on the Condensed Consolidated Statements of Operations.
Remaining Performance Obligations
Remaining Performance Obligations (“RPO”) are comprised of non-cancelable customer purchase orders for products and services that are awaiting transfer of control for revenue recognition under the applicable contract terms. As of April 29, 2023, the aggregate amount of RPO was $2.4 billion. As of April 29, 2023, Ciena expects approximately 86% of the RPO to be recognized as revenue within the next 12 months.
(4)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 $3.4 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 Statements 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 |

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.

(6) INTEREST AND OTHER INCOME, NET
The components of interest and other income, net, are as follows for the periods indicated (in thousands):

| Quarter Ended |  | Six Months Ended
| April 29, |  | April 30, |  | April 29, |  | April 30,
| 2023 |  | 2022 |  | 2023 |  | 2022
Interest income | $ | 10,416 |  |  | $ | 1,434 |  |  | $ | 17,530 |  |  | $ | 2,188 |
Gains (losses) on non-hedge designated foreign currency forward contracts | (2,795) |  |  | 2,334 |  |  | (4,564) |  |  | (1,926) |
Foreign currency exchange gains (losses) | 2,987 |  |  | (1,267) |  |  | 1,104 |  |  | 3,499 |
Gain on cost method equity investment | — |  |  | — |  |  | 26,455 |  |  | 4,120 |
Other | (2,057) |  |  | (1,693) |  |  | (1) |  |  | (3,387) |
Interest and other income, net | $ | 8,551 |  |  | $ | 808 |  |  | $ | 40,524 |  |  | $ | 4,494 |

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 $1.1 million and $3.5 million in foreign currency exchange rate gains for the first six months of fiscal 2023 and 2022, respectively, 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 six months of fiscal 2023 and 2022, Ciena recorded losses of $4.6 million and $1.9 million, respectively, from non-hedge designated foreign currency forward contracts.
(7) INCOME TAXES
The effective tax rate for the quarter and six months ended April 29, 2023 was higher than the effective tax rate for the
quarter and six months ended April 30, 2022, primarily due to the mandatory capitalization of research and development expenses in the second quarter and six months ended April 29, 2023.

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

| April 29, 2023 |  | October 29, 2022
Raw materials | $ | 753,374 |  |  | $ | 664,916 |
Work-in-process | 20,927 |  |  | 18,232 |
Finished goods | 307,997 |  |  | 258,584 |
Deferred cost of goods sold | 58,060 |  |  | 41,084 |
Gross inventories | 1,140,358 |  |  | 982,816 |
Reserve for inventory excess and obsolescence | (42,266) |  |  | (36,086) |
Inventories, net | $ | 1,098,092 |  |  | $ | 946,730 |

The increase in raw materials inventory is related to the steps Ciena has been taking to mitigate the impact on its customers and business of supply chain constraints in recent periods and a 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 six months of fiscal 2023, Ciena recorded a provision for inventory excess and obsolescence of $12.7 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.

(15) 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 April 29, 2023 and October 29, 2022, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability in certain currencies that are principally related to research and development activities. The notional amount of these contracts was approximately $308.1 million and $272.2 million as of April 29, 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 April 29, 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 $218.8 million and $108.0 million as of April 29, 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”), Ciena was exposed to floating rates of LIBOR interest on its 2025 Term Loan borrowings. Ciena
20

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 April 29, 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 $350.0 million as of April 29, 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 April 29, 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.
(16) 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 FASB 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):

|  | April 29, 2023 |  | October 29, 2022
|  | Principal Balance |  | Unamortized Discount |  | Deferred Debt Issuance Costs |  | Net Carrying Value |  | Net Carrying Value
2025 Term Loan |  | $ | 672,210 |  |  | $ | (767) |  |  | $ | (1,436) |  |  | $ | 670,007 |  |  | $ | 673,010 |

Deferred debt issuance costs that were deducted from the carrying amounts of the 2025 Term Loan totaled $1.4 million as of April 29, 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 $0.3 million during the first six 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 April 29, 2023, the estimated fair value of the 2025 Term Loan was $668.8 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
21

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 $492.7 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 as of the date indicated (in thousands):

|  | April 29, 2023 |  |
|  | Principal Balance |  | Unamortized Discount |  | Deferred Debt Issuance Costs |  | Net Carrying Value |  |
2030 Term Loan |  | $ | 500,000 |  |  | $ | (2,400) |  |  | $ | (4,667) |  |  | $ | 492,933 |  |  |

Deferred debt issuance costs that were deducted from the carrying amounts of the 2030 Term Loan totaled $4.7 million as of April 29, 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 $0.2 million during the first six months of fiscal 2023. The carrying value of the 2030 Term Loan listed above is also net of any unamortized debt discounts.
As of April 29, 2023, the estimated fair value of the 2030 Term Loan was $500.0 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):

|  | April 29, 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 |  |  | $ | (4,610) |  |  | $ | 395,390 |  |  | $ | 395,045 |  |  |

Deferred debt issuance costs that were deducted from the carrying amount of the 2030 Notes totaled $4.6 million as of April 29, 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 $0.3 million during the first six months of fiscal 2023 and was $0.2 million during the first six months of fiscal 2022.

As of April 29, 2023, the estimated fair value of the 2030 Notes was $349.0 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.
(17)ABL CREDIT FACILITY
On February 10, 2023, Ciena modified its senior secured asset-backed revolving credit facility (the “ABL Credit Facility”), which provides for a total commitment of $300.0 million to extend its maturity date to September 28, 2025. Other terms of the ABL Credit Facility remain unchanged.

(19) 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 for the periods indicated (in thousands, except per share amounts):
23

| Quarter Ended |  | Six Months Ended
| April 29, |  | April 30, |  | April 29, |  | April 30,
| 2023 |  | 2022 |  | 2023 |  | 2022
Net income | $ | 57,654 |  |  | $ | 38,922 |  |  | $ | 133,895 |  |  | $ | 84,745 |
Basic weighted average shares outstanding | 149,616 |  |  | 152,197 |  |  | 149,351 |  |  | 153,179 |
Effect of dilutive potential common shares | 531 |  |  | 1,147 |  |  | 501 |  |  | 1,401 |

(20) 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 six months of fiscal 2023, Ciena did not repurchase any additional shares of its common stock. As of April 29, 2023, Ciena (i) has repurchased 8.4 million shares for an aggregate purchase price of $500.0 million at an average price of $59.28 per share, and (ii) has an aggregate of $500.0 million authorized and 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 $22.0 million for the shares of Ciena’s stock repurchased during the first six 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.
(21) SHARE-BASED COMPENSATION EXPENSE
The following table summarizes share-based compensation expense for the periods indicated (in thousands):

Total share-based compensation expense | $ | 31,860 |  |  | $ | 26,673 |  |  | $ | 62,372 |  |  | $ | 50,970 |

As of April 29, 2023, total unrecognized share-based compensation expense was approximately $260.7 million, which relates to unvested stock unit awards and is expected to be recognized over a weighted-average period of 1.52 years.
24

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, the 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.

lead times or the implementation of security of supply strategies to address the supply constraints described below. We also believe some portion of these orders reflected pre-pandemic design wins for which orders were delayed due to the dynamics of the COVID-19 pandemic. Our order volumes began to moderate in the fourth quarter of fiscal 2022. We have continued to experience reduced orders relative to revenue in the first half of fiscal 2023 and order volumes lower than those received during the second quarter of fiscal 2021 through the third quarter of fiscal 2022. We believe this reduction has been in part due to customers no longer needing to place significant advanced orders as supply chain conditions and lead times have improved. However, over the longer term, we continue to believe that certain trends and shifts in business and consumer behaviors, including enterprise and consumer cloud network adoption, 5G, high-definition video, generative AI, and network operator focus on resilience and automation, represent positive, long-term opportunities for our business.
Backlog and Order Delivery Timing
Historically, a meaningful portion of our quarterly revenue was generated from customer orders received during that same quarter (which we refer to as “book to revenue”) and therefore less predictable and subject to fluctuation. As a result of elevated order volumes in recent prior periods and the supply chain constraints described below, however, we generated a significant backlog of customer orders, and, more recently, our quarterly results have been more significantly impacted by availability of supply, as well as customer delivery deferrals of existing backlog. Our backlog grew from $1.2 billion at the end of fiscal 2020 to $4.2 billion at the end of fiscal 2022. As supply chain conditions have begun to improve and we have been able to increase shipment volumes and reduce lead times, our backlog has decreased during the first half of fiscal 2023. We expect our backlog to continue to reduce during the remainder of fiscal 2023 as supply chain conditions improve and customers place fewer advanced orders. As that happens, we expect our reliance upon securing quarterly book to revenue orders to grow and those orders to represent a more typical composition of our quarterly revenue over time.
The timing and degree to which we fulfill our backlog will have a significant impact on our rate of revenue growth and can be affected by factors outside of our control, including the supply chain conditions and availability of components described below, and customer readiness and willingness to receive shipment against existing orders. Given their elevated order levels in recent prior periods, during the first half of fiscal 2023, certain customers, including communications service providers and cable and multiservice operators in North America and Web-scale providers, rescheduled deliveries of a portion of their existing orders, including in some cases until after the end of fiscal 2023. Accordingly, our results for a particular period can be difficult to predict. As a result of these and other factors, the timing of our fulfillment of backlog could cause some volatility in our results of operations and our backlog should not necessarily be viewed as an accurate indicator of revenue for any particular period. See the risk factors captioned “Our backlog may not be an accurate indicator of our level and timing of future revenues.” and “Our revenue, gross margin, and operating results can fluctuate significantly and unpredictably from quarter to quarter.” in Item 1A of Part II of this report for further discussion of risks related to our backlog and order delivery timing.
Supply Chain Constraints
In the face of demand across a range of industries, global supply for certain raw materials and components, including, in particular, semiconductor, integrated circuits, and other electronic components used in most of our products, experienced substantial constraint and disruption in recent periods. As a result, we experienced significant component shortages, extended lead times, increased costs, and unexpected cancellation or delay of previously committed supply of key components across our supplier base. While reliability of supply has begun to improve gradually, and the majority of our suppliers have been able to deliver by their promised, though extended, lead times, we continue to experience volatility from a small group of our suppliers of integrated circuit components that represent a small fraction of our overall materials, but which are essential for delivering finished products. This volatility can result in receiving fewer components than expected in a given period, which can adversely impact our revenue. It can also result in receiving more components than expected, as was the case in during the fourth quarter of fiscal 2022 and the first half of fiscal 2023, and which had a positive impact on our revenue. We expect supply chain challenges and the extended lead times and elevated supply chain costs we have experienced will persist at least through fiscal 2023. We expect these supply conditions to continue to impact our costs of goods sold in the near term and to adversely impact our ability to continue to reduce the cost to produce our products in a manner consistent with prior periods. It is unclear when the supply environment will become less volatile and what impacts it will have on our business and results of operations in future periods.
To mitigate the impact of these supply conditions on our business and customers, we have been placing advanced orders for inventory and accumulating components that are in available supply. We believe that this approach positions us to produce finished goods more quickly when supply constraints ease for those components in shorter supply. As a result, our inventory increased from $946.7 million at the end of fiscal 2022 to $1.2 billion at the end of the first quarter of fiscal 2023. As supply chain conditions have begun to improve and we have been able to fulfill more orders, our inventory has decreased to $1.1 billion at the end of the second quarter of fiscal 2023. We have also implemented additional mitigation strategies, including
28

expanding manufacturing capacity, implementing multi-sourcing activities, qualifying alternative parts, and redesigning products, and expect, over time, to realize certain benefits of these activities. Together with increased costs of supply, these mitigation strategies have impacted, and we expect them to continue to impact, our result of operations and cash from operations. See “Risk Factors” in Item 1A of Part II of this report for further discussion of risks related to our supply chain and our mitigation activities.
ABL Credit Facility
On February 10, 2023, we amended our existing ABL Credit Facility (as defined below) to, among other things, extend the maturity date of the ABL Credit Facility to September 28, 2025. See Note 17 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report for more information relating to the amendment of the ABL Credit Facility.
For additional information regarding our business, industry, market opportunity, competitive landscape, and strategy, see our 2022 Annual Report.
Consolidated Results of Operations
Operating Segments
Our results of operations are presented based on the following operating segments: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. See Note 3 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
Revenue
Currency Fluctuations
Approximately 15.9% and 15.3% of our revenue was non-U.S. Dollar-denominated during the second quarter and first six months of fiscal 2023, respectively, primarily including sales in Euros, Canadian Dollars, and British Pounds. During the second quarter of fiscal 2023, as compared to the second quarter of fiscal 2022, and during the first six months of fiscal 2023, as compared to the first six months of fiscal 2022, the U.S. Dollar primarily strengthened against these currencies. Consequently, our revenue for the second quarter and first six months of fiscal 2023 reported in U.S. Dollars were adversely impacted by approximately $8.2 million, or 0.7%, and $7.5 million or 0.3%, respectively.

Revenue by Geographic Region
Our operating segments engage in business and operations across three geographic regions: the United States, Canada, the Caribbean and Latin America (“Americas”); Europe, Middle East and Africa (“EMEA”); and Asia Pacific, Japan and India (“APAC”). The geographic distribution of our revenue can fluctuate significantly from period to period, and the timing of revenue recognition for large network projects, particularly outside of the United States, can result in large variations in geographic revenue results in any particular period. The increase in our Americas region revenue for the quarter and six months ended April 29, 2023 was primarily driven by increased sales in the United States. The increase in our APAC region revenue for the quarter and six months ended April 29, 2023 was primarily driven by increased sales in India and Australia. The increase in our EMEA region revenue for the quarter and six months ended April 29, 2023 was primarily driven by increased sales in France, Germany and the Netherlands.

Cost of Goods Sold and Gross Profit
There are a number of important factors or conditions that can adversely affect or cause our gross profit as a percentage of product or service revenue, or “gross margin,” to fluctuate on a quarterly basis. For example, early stages of new network builds also often include an increased concentration of lower margin “common” equipment, photonics sales and installation services, with the intent to improve margin as we sell channel cards and maintenance services to customers as they add capacity. The component elements that comprise our product cost of goods sold and services costs of goods sold, and certain factors that can cause gross margin to fluctuate, are described in detail in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Risk Factors” sections of our 2022 Annual Report.

•Gross profit increased by $85.9 million. Gross margin slightly increased by 80 basis points, primarily due to improved manufacturing efficiencies and product cost reductions, partially offset by a higher concentration of lower margin product mix and lower services margins. As supply conditions gradually improve, particularly for lower margin “common” equipment and photonics, we expect our gross margin to be adversely impacted during the remainder of fiscal 2023 as a result of a higher concentration of lower margin product mix. We also expect our gross margin to continue be adversely impacted due to the challenges and costs associated with the constrained supply environment described in “Overview” above.

•Gross profit on products increased by $85.6 million. Product gross margin increased by 160 basis points, primarily due to improved manufacturing efficiencies and product cost reductions, partially offset by a higher concentration of lower margin product mix.
•Gross profit on services increased by $0.3 million. Services gross margin decreased by 180 basis points, primarily due to lower margin on certain installation and deployment projects and losses incurred on certain Blue Planet software service projects. These decreases were partially offset by increased Platform Software services revenue.
Six months ended April 29, 2023 as compared to the six months ended April 30, 2022
•Gross profit increased by $157.7 million. Gross margin slightly decreased by 70 basis points, primarily due to lower services margins and a higher concentration of lower margin product mix, partially offset by product cost reductions and improved manufacturing efficiencies. As supply conditions gradually improve, particularly for lower margin “common” equipment and photonics, we expect our gross margin to continue to be adversely impacted during the remainder of fiscal 2023 as a result of a higher concentration of lower margin product mix. We also expect our gross margin to continue be adversely impacted due to the challenges and costs associated with the constrained supply environment described in “Overview” above.
•Gross profit on products increased by $170.5 million. Product gross margin slightly increased by 40 basis points, primarily due to product cost reductions and improved manufacturing efficiencies, partially offset by lower sales of software platforms.
•Gross profit on services decreased by $12.8 million. Services gross margin decreased by 440 basis points, primarily due to lower maintenance support revenue, lower margin on certain installation and deployment projects, and losses incurred on certain Blue Planet software service projects. These decreases were partially offset by an increase in Platform Software services revenue.
Operating Expense
Currency Fluctuations
Approximately 49.3% of our operating expense was non-U.S. Dollar-denominated during the second quarter of fiscal 2023, including expenses in Canadian Dollars, Indian Rupees, and Euros. During the second quarter of fiscal 2023, as compared to the second quarter of fiscal 2022, and during the first six months of fiscal 2023, as compared to the first six months of fiscal 2022, the U.S. Dollar primarily strengthened against these currencies. Consequently, our operating expense, net of hedging, reported in U.S. Dollars slightly decreased by approximately $12.0 million, or 3.1%, and $21.8 million, or 2.9%, respectively.
The component elements that comprise each of our operating expense categories in the table below are set forth in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of our 2022 Annual Report. The table below sets forth the changes in operating expense for the periods indicated (in thousands, except percentage data):

Quarter ended April 29, 2023 as compared to the quarter ended April 30, 2022
•Research and development expense benefited from $7.3 million as a result of foreign exchange rates, net of hedging, primarily due to a stronger U.S. Dollar in relation to the Canadian Dollar and Indian Rupee. Including the effect of foreign exchange rates, net of hedging, research and development expenses increased by $30.7 million. This increase
primarily reflects increases in employee headcount and related compensation costs, professional services and technology and related costs. The increase in employee headcount was partially due to our acquisitions of Benu Networks, Inc. (“Benu”) and Tibit Communications, Inc. (“Tibit”).
•Selling and marketing expense benefited from $3.6 million as a result of foreign exchange rates, primarily due to a stronger U.S. Dollar in relation to the Euro and Canadian Dollar. Including the effect of foreign exchange rates, sales and marketing expense increased by $5.1 million. This increase primarily reflects increases in employee headcount and related compensation costs, travel and entertainment costs, facility and information technology costs, and professional services.
•General and administrative expense benefited from $1.1 million as a result of foreign exchange rates, primarily due
to a stronger U.S. Dollar in relation to the Euro. Including the effect of foreign exchange rates, general and administrative expense increased by $5.4 million. This increase primarily reflects increases in employee headcount and related compensation costs and professional services.
•Significant asset impairments and restructuring costs reflects actions that we have taken with respect to our operations, global workforce, and facilities as part of a business optimization strategy to improve gross margin, constrain operating expense, redesign certain business processes, and restructure real estate facilities.
•Amortization of intangible assets increased by $0.9 million due to additional intangibles acquired in connection with our acquisitions of Benu and Tibit during the first quarter of fiscal 2023, partially offset by certain intangible assets having reached the end of their economic lives.
•Acquisition and integration costs remained relatively unchanged.
Six months ended April 29, 2023 as compared to the six months ended April 30, 2022
•Research and development expense benefited from $13.7 million as a result of foreign exchange rates, net of hedging, primarily due to fluctuations in the U.S. Dollar in relation to the Canadian Dollar and Indian Rupee. Including the effect of foreign exchange rates, net of hedging, research and development expenses increased by $64.0 million. This increase primarily reflects increases in employee headcount and related compensation costs, professional services, and technology and related costs. The increase in employee headcount was partially due to our acquisitions of Benu and Tibit. This increase also reflects the effect of a $4.4 million decrease in benefit from the Evolution of Networking Services through a Corridor in Quebec and Ontario for Research and Innovation (ENCQOR) project grant reimbursement program.
•Selling and marketing expense benefited from $6.3 million as a result of foreign exchange rates, primarily due to a stronger U.S. Dollar in relation to the Euro and Canadian Dollar. Including the effect of foreign exchange rates, sales and marketing expense increased by $10.1 million. This increase primarily reflects an increase in professional services and travel and entertainment costs, partially offset by a decrease in employee-related compensation costs related to sales commissions.
•General and administrative expense benefited from $1.8 million as a result of foreign exchange rates, primarily due
to a stronger U.S. Dollar in relation to the Euro and Canadian Dollar. Including the effect of foreign exchange rates, general and administrative expense increased by $11.8 million. This increase primarily reflects increases in employee headcount and related compensation costs, professional services, and bad debt expense.
•Significant asset impairments and restructuring costs reflects actions that we have taken with respect to our operations, global workforce, and facilities as part of a business optimization strategy to improve gross margin, constrain operating expense, redesign certain business processes, and restructure real estate facilities.
•Amortization of intangible assets reflects certain intangible assets having reached the end of their economic lives, partially offset by additional intangibles acquired in connection with our acquisitions of Benu and Tibit during the first quarter of fiscal 2023.

•Interest and other income, net increased by $7.7 million, primarily resulting from higher interest income on our investments. These increases were partially offset by the impact of foreign exchange rates on assets and liabilities denominated in a currency other than the relevant functional currency, net of hedging activity.
•Interest expense increased by $11.9 million, primarily due to higher interest rates on our floating rate debt, net of hedging activity, and additional outstanding indebtedness, including the 2030 Term Loan incurred in the first quarter of fiscal 2023. For more information on our short-term and long-term debt, see Note 16 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
•Provision for income taxes increased by $21.5 million, primarily due to an increase in pre-tax income in the second quarter of fiscal 2023 as compared to the second quarter of fiscal 2022. The effective tax rate for the second quarter of fiscal 2023 was higher than the effective tax rate for the second quarter of fiscal 2022, primarily due to the mandatory capitalization of research and development expenses in the second quarter of fiscal 2023.
Six months ended April 29, 2023 as compared to the six months ended April 30, 2022
•Interest and other income, net increased by $36.0 million, primarily resulting from the remeasurement of our previously held investment in Tibit to fair value, which resulted in a gain on our cost method equity investment of $26.5 million, and higher interest income on our investments. These increases were partially offset by the impact of foreign exchange rates on assets and liabilities denominated in a currency other than the relevant functional currency, net of hedging activity. For more information on our acquisitions, see Note 4 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
•Interest expense increased by $19.1 million, primarily due to higher interest rates on our floating rate debt, net of hedging activity, and additional outstanding indebtedness, including our 2030 Notes issued in the first quarter of fiscal 2022 and the 2030 Term Loan incurred in the first quarter of fiscal 2023. For more information on our short-term and long-term debt, see Note 16 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
•Provision for income taxes increased by $37.4 million, primarily due to an increase in pre-tax income in the first six months of fiscal 2023 as compared to the first six months of fiscal 2022. The effective tax rate for the first six months of fiscal 2023 was higher than the effective tax rate for the first six months of fiscal 2022, primarily due to the mandatory capitalization of research and development expenses in the first six months of fiscal 2023.

Liquidity and Capital Resources
Overview. For the six months ended April 29, 2023, we used $35.8 million of cash in operating activities as our working capital requirements of approximately $310.6 million exceeded our net income (adjusted for non-cash charges) of approximately $274.8 million. For additional details, see “Cash Used In Operating Activities” below.
Despite our cash used in operations, our total cash, cash equivalents, and investments increased by $159.7 million during the first six months of fiscal 2023. This increase principally reflects proceeds from the issuance of the 2030 Term Loan, which provided $492.7 million in cash, net of paid debt issuance costs, and proceeds from the issuance of equity under our employee stock purchase plan which provided $14.7 million in cash during the six months ended April 29, 2023. In addition to the cash used in operations, uses of cash also included the following items: (i) cash used for the acquisition of businesses of $230.0 million; (ii) cash used to fund our investing activities for capital expenditures totaling $58.0 million; and (iii) stock repurchases on vesting of our stock unit awards to employees relating to tax withholding of $22.0 million.
See Notes 4, 16 and 20 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report for additional information on these transactions.
The following table sets forth changes in our cash, cash equivalents and investments in marketable debt securities for the periods indicated (in thousands):
37

| April 29, 2023 |  | October 29, 2022 |  | Increase (decrease)
Cash and cash equivalents | $ | 1,167,695 |  |  | $ | 994,352 |  |  | $ | 173,343 |
Short-term investments in marketable debt securities | 150,464 |  |  | 153,989 |  |  | (3,525) |
Long-term investments in marketable debt securities | 25,237 |  |  | 35,385 |  |  | (10,148) |
Total cash, cash equivalents, and investments in marketable debt securities | $ | 1,343,396 |  |  | $ | 1,183,726 |  |  | $ | 159,670 |

Principal Sources of Liquidity. Our principal sources of liquidity on hand include our cash, cash equivalents, and investments, which, as of April 29, 2023 totaled $1.3 billion, as well as the senior secured asset-backed revolving credit facility to which we and certain of our subsidiaries are parties (the “ABL Credit Facility”). The ABL Credit Facility provides for a total commitment of $300.0 million with a maturity date of September 28, 2025, as modified on February 10, 2023. See Note 17 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report. We principally use the ABL Credit Facility to support the issuance of letters of credit that arise in the ordinary course of our business and thereby to reduce our use of cash required to collateralize these instruments. As of April 29, 2023, letters of credit totaling $89.7 million were collateralized by our ABL Credit Facility. There were no borrowings outstanding under the ABL Credit Facility as of April 29, 2023.
Foreign Liquidity. Cash, cash equivalents, and short-term investments held by our foreign subsidiaries was $304.4 million as of April 29, 2023. We intend to reinvest indefinitely our foreign earnings. If we were to repatriate the accumulated historical foreign earnings, the provisional amount of unrecognized deferred income tax liability related to foreign withholding taxes would be approximately $35.0 million.
Stock Repurchase Authorization. On December 9, 2021, we announced that our Board of Directors authorized a program to repurchase up to $1.0 billion of our common stock, which replaced in its entirety the previous stock repurchase program authorized in fiscal 2019. During the first six months of fiscal 2023, we did not repurchase any additional common stock under the stock repurchase program, and $500.0 million remained under the current repurchase authorization as of April 29, 2023. The amount and timing of any further repurchases under our stock repurchase program are subject to a variety of factors including liquidity, cash flow, stock price, and general business and market conditions. The program may be modified, suspended, or discontinued at any time. See Note 20 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
Liquidity Position. Based on past performance and current expectations, we believe that cash from operations, cash, cash equivalents, investments, and other sources of liquidity, including our ABL Credit Facility, will satisfy our currently anticipated working capital needs, capital expenditures, and other liquidity requirements associated with our operations through the next 12 months and the reasonably foreseeable future. We regularly evaluate our liquidity position, debt obligations, and anticipated cash needs to fund our operating or investment plans, and will continue to consider capital raising and other market opportunities that may be available to us. We regularly evaluate alternatives to manage our capital structure and market opportunities to enhance our liquidity and provide further operational and strategic flexibility.

Total cash used for working capital | $ | (310,608) |

As compared to the end of fiscal 2022:
•The $116.9 million of cash used in accounts receivable during the first six months of fiscal 2023 reflects increased sales volume at the end of the second quarter of fiscal 2023;
•The $162.1 million of cash used in inventories during the first six months of fiscal 2023 primarily reflects increases in raw materials inventory related to the steps that we are taking to mitigate the impact of current supply chain constraints and the global market shortage of semiconductor parts described in “Overview” above;
•The $41.5 million of cash used in prepaid expense and other during the first six months of fiscal 2023 primarily reflects increases in contract assets and other non-trade receivables;
•The $55.8 million of cash used in accounts payable, accruals, and other obligations during the first six months of fiscal 2023 primarily reflects payments to suppliers, partially offset by increases in income taxes payable;
•The $68.8 million of cash provided by deferred revenue during the first six months of fiscal 2023 represents an increase in advanced payments received on multi-year maintenance contracts from customers prior to revenue recognition; and
•The $3.1 million of cash used in operating lease assets and liabilities, net, during the first six months of fiscal 2023 represents cash paid for operating lease payments in excess of operating lease costs.
Our days sales outstanding (“DSOs”) increased from 86 for first six months of fiscal 2022 to 100 for the first six months of fiscal 2023. The calculation of DSOs includes accounts receivables, net and contract assets for unbilled receivables, net included in prepaid expenses and other. Our inventory turns decreased from 3.1 for the first six months of fiscal 2022 to 1.9 for the first six months of fiscal 2023 due to the increases in inventory as described in “Overview” above.

Our contractual obligations have not changed materially since October 29, 2022, except for the items listed below. For a summary of our contractual obligations, see Item 7 of Part II of the 2022 Annual Report.
Purchase Order Obligations. As of April 29, 2023 we had $2.2 billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. In certain instances, we are permitted to cancel, reschedule, or adjust these orders. Consequently, only a portion of this amount relates to firm, non-cancelable, and unconditional obligations.
Debt. As of April 29, 2023, we had $500.0 million outstanding principal associated with our 2030 Term Loan, with $5.0 million payable within 12 months. Interest on the 2030 Term Loan and payments due under the interest rate swaps are variable and calculated using the rate in effect on the balance sheet date. Future interest payments associated with the 2030 Term Loan total $238.4 million, with $30.1 million payable within 12 months. For additional information about the 2030 Term Loan, see Note 16 to our Condensed Consolidated Financial Statements included in Item I of Part I of this report.
Critical Accounting Policies and Estimates
The preparation of our consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, and expense, and related disclosure of contingent assets and liabilities. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty. On an ongoing basis, we reevaluate our estimates, including those related to revenue recognition, share-based compensation, bad debts, inventories, intangible and other
40

long-lived assets, goodwill, income taxes, warranty obligations, restructuring, derivatives and hedging, and contingencies and litigation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. 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 our estimates and actual results, our consolidated financial statements will be affected.
Our critical accounting policies and estimates have not changed materially since October 29, 2022. For a discussion of our critical accounting policies and estimates, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Item 7 of Part II of our 2022 Annual Report.
Effects of Recent Accounting Pronouncements
See Note 2 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report for information relating to our discussion of the effects of recent accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. For a discussion of quantitative and qualitative disclosures about market risk, see Item 7A of Part II of our 2022 Annual Report.
Item 4. Controls and Procedures
Disclosure Controls and Procedures
As of the end of the period covered by this report, we carried out an evaluation under the supervision and with the participation of management, including our Chief Executive Officer and Chief Financial Officer, of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended) during the most recently completed fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II — OTHER INFORMATION
Item 1. Legal Proceedings
The information set forth under the heading “Litigation” in Note 23 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report, is incorporated herein by reference.
Item 1A. Risk Factors
Investing in our securities involves a high degree of risk. Before investing in our securities, you should consider carefully the information contained in this report and in our 2022 Annual Report, including the risk factors identified in Item 1A of Part I thereof (Risk Factors). This report contains forward-looking statements that involve risks and uncertainties. See “Cautionary Note Regarding Forward-Looking Statements” in “Management’s Discussion and Analysis of Financial Conditions and Results of Operations” above. Our actual results could differ materially from those contained in the forward-looking statements. Any of the risks discussed in our 2022 Annual Report, in this report, in other reports we file with the SEC, and other risks we have not anticipated or discussed, could have a material adverse impact on our business, financial condition, or results of operations. Except as set forth below, there has been no material change to our Risk Factors from those presented in our 2022 Annual Report.
Our revenue, gross margin, and operating results can fluctuate significantly and unpredictably from quarter to quarter.
Our revenue, gross margin, and results of operations can fluctuate significantly and unpredictably from quarter to quarter. Our budgeted expense levels are based on our visibility into customer spending plans and our projections of future revenue and
41

gross margin. Visibility into customer spending levels can be uncertain, spending patterns are subject to change, and reductions in our expense levels can take significant time to implement. Historically, a significant portion of our quarterly revenue was generated from customer orders received during that same quarter (which we refer to as “book to revenue”) and therefore less predictable and subject to fluctuation due to a quarterly shortfall in orders from expectations. During fiscal 2022, however, we generated a significant backlog of customer orders, and more recently, our quarterly results have been more significantly impacted by availability of supply, as well as customer delivery deferrals of existing backlog. Given their elevated order levels in prior periods, during the first half of fiscal 2023, certain customers, including communications service providers and cable and multiservice operators in North America and Web-scale providers, have rescheduled deliveries of existing orders, including in some cases until after the end of fiscal 2023. We expect our backlog to continue to reduce during the remainder of fiscal 2023 as supply chain conditions improve and customers place fewer advanced orders. As that happens, we expect our reliance upon securing quarterly book to revenue orders to grow and those orders to represent a more typical composition of our quarterly revenue over time. However, within these dynamics, our results for a particular period can be difficult to predict. These dynamics, as well as a range of factors, including those set forth below, can materially adversely affect quarterly revenue, gross margin, and operating results:
•changes in spending levels or network deployment plans by customers, particularly with respect to our service provider and Web-scale provider customers;
•order timing and volume, including book to revenue orders;
•the timing of revenue recognition on sales, particularly relating to large orders;
•availability of components and manufacturing capacity;
•shipment and delivery timing;
•backlog levels;
•the level of competition and pricing pressure in our industry;
•the pace and impact of price erosion that we regularly encounter in our markets;
•the impact of commercial concessions or unfavorable commercial terms required to maintain incumbency or secure new opportunities with key customers;
•the mix of revenue by product segment, geography, and customer in any particular quarter;
•our level of success in achieving targeted cost reductions and improved efficiencies in our supply chain;
•our incurrence of start-up costs, including lower margin phases of projects required to support initial deployments, gain new customers or enter new markets;
•our level of success in accessing new markets and obtaining new customers;
•long- and short-term changing behaviors or customer needs that impact demand for our products and services or the products and services of our customers;
•technology-based price compression and our introduction of new platforms with improved price for performance;
•changing market, economic, and political conditions, including the impact of tariffs and other trade restrictions or efforts to withdraw from or materially modify international trade agreements;
•factors beyond our control such as natural disasters, climate change, acts of war or terrorism, and public health emergencies, such as the COVID-19 pandemic;
•the financial stability of our customers and suppliers;
•consolidation activity among our customers, suppliers. and competitors;
•installation service availability and readiness of customer sites;
•adverse impact of foreign exchange; and
•seasonal effects in our business.
As a result of these factors and other conditions affecting our business and operating results, we believe that quarterly comparisons of our operating results are not necessarily a good indication of possible future performance. Quarterly fluctuations from the above factors may cause our revenue, gross margin, and results of operations to underperform in relation to our guidance, long-term financial targets or the expectations of financial analysts or investors, which may cause volatility or decreases in our stock price.
Our backlog may not be an accurate indicator of our level and timing of future revenues.
As a result of order volumes growth in prior periods, together with supply chain constrains, our backlog grew from $1.2 billion at the end of fiscal 2020 to $4.2 billion at the end of fiscal 2022. However, our order volumes began to moderate in the fourth quarter of fiscal 2022. We expect order volumes to continue to moderate and normalize over time and we do not expect the very high level of orders we experienced in earlier periods in fiscal 2021 and fiscal 2022 to continue in the long-term. As order growth moderates and supply chain conditions improve, we expect our backlog to reduce, which was the case in the first half of fiscal 2023. Backlog may be fulfilled several quarters following receipt of a purchase order, either due to customer schedules or delays caused by supply chain constraints. Generally, our customers may cancel, delay delivery or change their orders with limited advance notice, or they may decide not to accept our products and services, although instances of both
42

cancellation and non-acceptance have been rare historically. Backlog also includes certain service obligations that may relate to a multi-year support period. As a result, backlog should not necessarily be viewed as an accurate indicator of future revenue for any particular period.
Accurately matching necessary inventory levels to customer demand within the current environment is challenging, and we may incur additional costs or be required to write off significant inventory that would adversely impact our results of operations.
From the second quarter of fiscal 2021 through the third quarter of fiscal 2022, we received unprecedented orders for our products and services, and matching necessary inventory to fulfill that demand within the current supply constrained environment is challenging. We have taken and continue to take a number of steps to mitigate these challenges, including extending our purchase commitments and placing non-cancellable, advanced orders with or through suppliers, particularly for long lead time components. As of April 29, 2023 we had $2.2 billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. We have also been expanding our manufacturing capacity and have been accumulating raw materials inventory of components that are available, in some cases with expanded lead times, in an effort to prepare us to be able to produce finished goods more quickly when supply constraints ease for certain common components, including integrated circuit components, for which delivery continues to be delayed. As a result of this strategy, our inventory has increased from $374.3 million at the end of fiscal 2021 to $1.1 billion at the end of the second quarter of fiscal 2023. These inventory practices, and their associated costs, have had, and we expect them to continue to have, an adverse impact on our cash from operations.
These inventory practices also further introduce obsolescence risk that can impact our results of operations and financial condition. If our customers were to cancel or delay orders as a result of increased lead times or otherwise, inventory could become obsolete and we could be required to write off or write down the inventory associated with those orders. In addition, if customers were to cancel or delay existing or forecasted orders for which we have significant outstanding commitments to our contract manufacturers or suppliers, we may be required to purchase inventory under these commitments that we are unable to sell. If we are required to write off or write down a significant amount of inventory, our results of operations for the applicable period would be materially adversely affected. Our inability to effectively manage the matching of inventory with customer demand within the current environment could adversely impact our results of operations and financial condition, and could result in loss of revenue, increased costs, or delays that could adversely impact customer satisfaction.
We rely on third-party contract manufacturers, and our business and results of operations may be adversely affected by risks associated with their businesses, financial condition, and the geographies in which they operate.
We rely on third-party contract manufacturers, including those with facilities in Canada, Mexico, Thailand, and the United States, to perform a substantial portion of our supply chain activities, including component sourcing, manufacturing, product testing and quality, and fulfillment and logistics relating to the distribution and support of our products. There are a number of risks associated with our dependence on contract manufacturers, including:
•reduced control over delivery schedules and planning;
•reliance on the quality assurance procedures of third parties;
•potential uncertainty regarding manufacturing yields and costs;
•availability of manufacturing capability and capacity, particularly during periods of high demand;
•the impact of wage inflation and labor shortages on cost;
•the impact of supply chain constraints on our contract manufacturers’ costs and business models;
•risks associated with the ability of our contract manufacturers to perform to our manufacturing needs;
•risks and uncertainties associated with the locations or countries where our products are manufactured, including potential manufacturing disruptions caused by social, geopolitical, environmental, or health factors, including pandemics or widespread health epidemics such as the COVID-19 pandemic;
•risks associated with data security breaches, interdiction, or cyber-attacks targeting our third-party manufacturers, including manufacturing disruptions or unauthorized access to information;
•changes in law or policy governing tax, trade, manufacturing, development, and investment in the countries where we currently manufacture our products, including the World Trade Organization Information Technology Agreement or other free trade agreements;
•inventory liability for excess and obsolete supply;
•limited warranties provided to us; and
•potential misappropriation of our intellectual property.
43

If our contract manufacturers are unable or unwilling to manufacture our products or components of our products, or if we experience a disruption in manufacturing, we may be required to identify and qualify alternative manufacturers, which could cause us to be delayed in or unable to meet our supply requirements to our customers. The process of qualifying a new contract manufacturer and commencing volume production is expensive and time-consuming, and if we are required to change or qualify a new contract manufacturer, we would likely experience significant business disruption and could lose revenue and damage our existing customer relationships. These and other risks associated with our contract manufacturers’ businesses, financial condition, and the geographies in which they operate could impair our ability to fulfill orders, harm our sales and impact our reputation with customers in ways that adversely impact our business and results of operations.
Outstanding indebtedness under our senior secured credit facilities and senior unsecured notes may adversely affect our liquidity and results of operations and could limit our business.
We are a party to credit agreements relating to a $300.0 million senior secured asset-based revolving credit facility, an outstanding senior secured term loan with approximately $672.2 million due 2025, an outstanding senior secured term loan with approximately $500.0 million due 2030, and an outstanding senior unsecured indenture pursuant to which we issued $400.0 million in aggregate principal amount of 4.00% senior notes due 2030. The agreements governing these credit facilities contain certain covenants that limit our ability, among other things, to incur additional debt, create liens and encumbrances, pay cash dividends, redeem or repurchase stock, enter into certain acquisition transactions or transactions with affiliates, repay certain indebtedness, make investments, or dispose of assets. The agreements also include customary remedies, including the right of the lenders to take action with respect to the collateral securing the loans, that would apply should we default or otherwise be unable to satisfy our debt obligations.
Our indebtedness could have important negative consequences, including:
•increasing our vulnerability to adverse economic and industry conditions;
•limiting our ability to obtain additional financing, particularly in unfavorable capital and credit market conditions;
•debt service and repayment obligations that may adversely impact our results of operations and reduce the availability of cash resources for other business purposes;
•limiting our flexibility in planning for, or reacting to, changes in our business and the markets; and
•placing us at a possible competitive disadvantage to competitors that have better access to capital resources.
We may also enter into additional debt transactions or credit facilities, including equipment loans, working capital lines of credit, senior notes, and other long-term debt, which may increase our indebtedness and result in additional restrictions on our business. In addition, major debt rating agencies regularly evaluate our debt based on a number of factors. There can be no assurance that we will be able to maintain our existing debt ratings, and failure to do so could adversely affect our cost of funds, liquidity and access to capital markets.
