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 28, 2023 was derived from audited financial statements, but does not include all disclosures required by GAAP. However, Ciena believes that the disclosures are adequate to understand the information presented herein. The operating results for interim periods are not necessarily indicative of the operating results for the entire year. These financial statements should be read in conjunction with Ciena’s audited consolidated financial statements and the notes thereto included in Ciena’s Annual Report on Form 10-K for the fiscal year ended October 28, 2023 (the “2023 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 2024 is a 53-week fiscal year with the additional week occurring in the fourth quarter. Fiscal 2023 was a 52-week fiscal year.

(2) SIGNIFICANT ACCOUNTING POLICIES
Except for the changes in certain policies described below, 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 2023 Annual Report.

Newly Issued Accounting Standards - Effective

In October 2021, the FASB issued 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 was effective for Ciena beginning in the first quarter of fiscal 2024 without any material impact on its consolidated financial position, results of operations and related disclosures.

Newly Issued Accounting Standards - Not Yet Effective

In November 2023, the FASB issued ASU No. 2023-07 (“ASU 2023-07”), Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023 on a retrospective basis. Early adoption is permitted. Ciena is currently evaluating the impact of this accounting standard update on its consolidated financial statements and related disclosures.

In December 2023, the FASB issued ASU No. 2023-09 (“ASU 2023-09”), Income Taxes (Topic 740): Improvement to Income Tax Disclosures to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 is effective for annual periods beginning after December 15, 2024; however, early adoption is permitted. ASU 2023-09 allows for
8


adoption using either a prospective or retrospective method. Ciena is currently evaluating the impact of this accounting standard update on its 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 January 27, 2024Balance at October 28, 2023
Accounts receivable, net$865,239 $1,003,876 
Contract assets for unbilled accounts receivable, net$151,572 $150,312 
Deferred revenue$243,270 $228,460 

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 on the Condensed Consolidated Balance Sheets. See Note 10 below.

Contract liabilities consist of deferred revenue and represent advanced payments against non-cancelable customer orders received prior to revenue recognition. Ciena recognized approximately $70.6 million and $67.9 million of revenue during the first three months of fiscal 2024 and 2023, respectively, that was included in the deferred revenue balance at October 28, 2023 and October 29, 2022, respectively. Revenue recognized due to changes in transaction price from performance obligations satisfied or partially satisfied in previous periods was immaterial during the three months ended January 27, 2024 and January 28, 2023.

Capitalized Contract Acquisition Costs

Capitalized contract acquisition costs consist of deferred sales commissions, and were $27.8 million and $30.2 million as of January 27, 2024 and October 28, 2023, respectively. Capitalized contract acquisition costs were included in (i) prepaid expenses and other and (ii) other long-term assets on the Condensed Consolidated Balance Sheets. The amortization expense associated with these costs was $7.7 million and $7.2 million during the first three months of fiscal 2024 and 2023, 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 January 27, 2024, the aggregate amount of RPO was $1.7 billion. As of January 27, 2024, Ciena expects approximately 83% of the RPO to be recognized as revenue within the next 12 months.

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

20242023
Interest income$15,177 $7,121 
Gains (losses) on non-hedge designated foreign currency forward contracts3,112 (1,769)

Gain on cost method equity investments, net 26,455 
Other1,553 2,055 
Interest and other income, net$10,650 $31,973 

During the first quarter of fiscal 2023, the acquisition of Tibit Communications, Inc. (“Tibit”) by Ciena 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.
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 $9.2 million and $1.9 million during the first three months of fiscal 2024 and fiscal 2023, respectively, in foreign currency exchange rate losses 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
13


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 2024, Ciena recorded gains of $3.1 million from non-hedge designated foreign currency forward contracts. During the first three months of fiscal 2023, Ciena recorded losses of $1.8 million from non-hedge designated foreign currency forward contracts.

(6) INCOME TAXES

The effective tax rate for the quarter ended January 27, 2024 was higher than the effective tax rate for the quarter ended January 28, 2023, primarily due to the tax benefit of a gain on a cost method equity investment in the first quarter of fiscal 2023.

Reserve for inventory excess and obsolescence(54,019)(50,003)
Inventories, net$984,886 $1,050,838 

    Ciena has been expanding its manufacturing capacity and had been accumulating raw materials inventory of components that are available, in some cases with expanded lead times, in an effort to prepare Ciena to produce finished goods more quickly upon the easing of supply constraints for certain common components. During the first quarter of fiscal 2024 Ciena reduced its raw materials inventory of components due to the consumption of raw materials in excess of purchases. The increase in finished goods inventories resulted primarily from planned fulfillment of customer advance orders for which some deliveries have been rescheduled outside of the first quarter of fiscal 2024.

16


Ciena makes estimates about future customer demand for its products when establishing the appropriate reserve for excess and obsolete inventory. For the periods presented, future demand was calculated using both customer backlog and future forecasted sales. Generally, Ciena’s customers may cancel or change their orders with limited advance notice, or they may decide not to accept its products and services, although instances of both cancellation and non-acceptance are rare. 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 2024, Ciena recorded a provision for inventory excess and obsolescence of $10.4 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.

(12) 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 27, 2024 and October 28, 2023, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability in certain currencies for expenses principally related to research and development activities. The notional amount of these contracts was approximately $349.5 million and $367.3 million as of January 27, 2024 and October 28, 2023, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges.

As of January 27, 2024 and October 28, 2023, Ciena had forward contracts designated as net investment hedges to minimize the effect of foreign exchange rate movements on its net investments in foreign operations. The notional amount of these contracts was approximately $48.1 million and $48.0 million as of January 27, 2024 and October 28, 2023, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as net investment hedges.

As of January 27, 2024 and October 28, 2023, Ciena had forward contracts in place to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. The notional amount of these contracts was approximately $190.8 million and $226.3 million as of January 27, 2024 and October 28, 2023, 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 13 below) and has hedged such risk by entering into floating-to-fixed interest rate swap arrangements.

In April 2022, Ciena entered into forward starting interest rate swaps to fix the Secured Overnight Financing Rate (“SOFR”) for the first $350.0 million of its floating rate debt at 2.968% from September 2023 through September 2025 (“2025 interest rate swaps”). The total notional amount of the 2025 interest swaps was $350.0 million as of January 27, 2024.

In January 2023, Ciena entered into interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.47% through January 2028 (“2028 interest rate swaps”). The total notional amount of these interest rate swaps in effect as of January 27, 2024 was $350.0 million.

In December 2023, Ciena entered into forward starting interest rate swaps to fix SOFR for an additional $350.0 million of its floating rate debt at 3.287% from September 2025 through December 2028 (“2028 forward starting interest rate swaps”). The total notional amount of the 2028 forward starting interest rate swaps effective September 2025 was $350.0 million as of January 27, 2024.

Ciena expects the variable rate payments to be received under the terms of these interest rate swaps to offset exactly the forecasted variable rate payments on the equivalent notional amount of the 2030 New Term Loan (as defined in Note 13 below). These derivative contracts have been designated as cash flow hedges.

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

(13) SHORT-TERM AND LONG-TERM DEBT

Outstanding Term Loan Payable

2030 New Term Loan

On October 24, 2023, Ciena entered into an Incremental Amendment Agreement to its Credit Agreement to which Ciena incurred a new tranche of senior secured term loans in an aggregate principal amount of $1.2 billion maturing on October 24, 2030 (the “2030 New Term Loan”) and a new senior secured revolving credit facility of $300.0 million (the “Revolving Credit Facility”). The 2030 New Term Loan requires Ciena to make installment payments of $2.9 million quarterly, or $11.7 million annually, with the remaining balance payable at maturity.    

The net carrying value of the 2030 New Term Loan was comprised of the following as of the date indicated (in thousands):
January 27, 2024October 28, 2023
Principal BalanceUnamortized DiscountDeferred Debt Issuance CostsNet Carrying ValueNet Carrying Value
2030 New Term Loan$1,170,000 $(4,934)$(6,157)$1,158,909 $1,159,371 

Deferred debt issuance costs that were deducted from the carrying amount of the 2030 New Term Loan totaled $6.2 million as of January 27, 2024 and $5.5 million at October 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 New Term Loan. The amortization of deferred debt issuance costs for the 2030 New Term Loan is included in interest expense and was approximately $0.2 million during the first three months of fiscal 2024.

As of January 27, 2024, the estimated fair value of the 2030 New Term Loan was $1.2 billion. The 2030 New Term Loan is categorized as Level 2 in the fair value hierarchy. Ciena estimated the fair value of its 2030 New Term Loan using a market approach based on observable inputs, such as current market transactions involving comparable securities.

Refinanced Term Loans

The proceeds of the 2030 New Term Loan, net of original issuance discount, was used to repay in full $1.2 billion of outstanding principal of the 2025 Term Loan (as defined below) and the 2030 Term Loan (as defined below), together the Refinanced Term Loans, including accrued interest.

2025 Term Loan

On January 19, 2023, pursuant to the Incremental Agreement (as defined below) to the Credit Agreement, the Credit Agreement was amended to replace LIBOR with SOFR for Ciena’s senior secured term loan maturing on September 28, 2025 (the “2025 Term Loan”) in response to pending impact of FASB Accounting Standards Codification 848, Reference Rate Reform. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate method, 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 for the first three months of fiscal 2023.

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, 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 $492.5 million in proceeds from the 2030 Term Loan were used for general corporate purposes. Deferred debt issuance costs are amortized using the straight-line method, which approximates the effect of the effective interest rate method, 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 nominal for the first three months of fiscal 2023.

Outstanding Senior Notes Payable

2030 Notes
19



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

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

2030 Notes$400,000 $(4,091)$395,909 $395,735 

Deferred debt issuance costs that were deducted from the carrying amount of the 2030 Notes totaled $4.1 million as of January 27, 2024 and $4.3 million as of October 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 Notes. The amortization of deferred debt issuance costs for the 2030 Notes is included in interest expense, and was approximately $0.2 million during both the first three months of fiscal 2024 and fiscal 2023.

As of January 27, 2024, the estimated fair value of the 2030 Notes was $363.5 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.

(15) EARNINGS PER SHARE CALCULATION

20


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.

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 2024, Ciena repurchased an additional 0.7 million shares of its common stock for an aggregate purchase price of $32.0 million at an average price of $46.30 per share. As of January 27, 2024, Ciena (i) has repurchased 14.8 million shares for an aggregate purchase price of $782.0 million at an average price of $52.85 per share and (ii) has an aggregate of $218.0 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 $10.1 million for the shares of Ciena’s stock repurchased during the first three months of fiscal 2024 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.

Overview

This Management’s Discussion and Analysis of Financial Condition and Results of Operations is designed to provide an understanding of Ciena’s financial condition, results of operations, and cash flows, and should be read in conjunction with our Condensed Consolidated Financial Statements and the accompanying notes thereto included in Item 1 of Part I of this report and in Item 8 of Part II of our 2023 Annual Report.

We are a network platform, software, and services company, providing solutions that enable a wide range of network operators to deploy and manage next-generation networks that deliver services to businesses and consumers. We provide hardware, software, and services that support the delivery of video, data, and voice traffic over core, metro, aggregation, and
24


access communications networks. Our solutions are used globally by communications service providers, cable and multiservice operators, cloud providers, submarine network operators, governments, and enterprises across multiple industry verticals. Our portfolio is designed to enable the Adaptive Network, which is our vision for a network end state that leverages a programmable and scalable network infrastructure, driven by software control and automation capabilities, that is informed by analytics and intelligence. Our solutions include Networking Platforms, including our Optical Networking and Routing and Switching portfolios, which can be applied from the network core to end-user access points, and which allow network operators to scale capacity, increase transmission speeds, allocate traffic efficiently and adapt dynamically to changing end-user service demands. To complement our Networking Platforms, we offer Platform Software, which includes our Navigator Network Control SuiteTM (“Navigator NCS”), which we previously referred to as Manage, Control, and Plan (MCP), applications that deliver advanced multi-layer domain control and operations. Through our Blue Planet Software, we also enable complete service lifecycle management automation with productized operational support systems (OSS), which include inventory, orchestration and assurance solutions that help our customers to achieve closed loop automation across multi-vendor and multi-domain environments.

Order Volumes

From the second quarter of fiscal 2021 through the third quarter of fiscal 2022, we received an unprecedented volume of orders for our products and services, which significantly exceeded our revenue and historical order volumes. We believe some portion of these large orders reflected customer acceleration of future orders due to a constrained supply environment, as well as orders which were delayed due to the dynamics of the COVID-19 pandemic. Our order volumes began to moderate in the fourth quarter of fiscal 2022, and we experienced order levels below revenue during fiscal 2023 and the first quarter of fiscal 2024, particularly from our communications service provider customers. Our expected return to more typical order patterns with our service provider customers in fiscal 2024 is taking longer than anticipated. We believe this is, in part, due to service providers in North America working through relatively high levels of inventory previously acquired, which has been made more difficult due to challenges installing and deploying equipment, including site readiness and access to fiber or other resources. In addition, in certain international geographies, we believe that caution driven by macroecononic concerns and market-specific issues are contributing to lower-than-expected order volumes from service providers. We expect these dynamics with our service provider customers to persist for the next few quarters. Notwithstanding these near-term impacts, 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 drivers of bandwidth demand and 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 was therefore less predictable and subject to fluctuation. As a result of elevated order volumes during portions of fiscal 2021 and fiscal 2022, however, our backlog grew from $1.2 billion at the end of fiscal 2020 to $4.2 billion at the end of fiscal 2022. Accordingly, our revenue in recent fiscal years has been more significantly impacted by factors including availability of supply and customer delivery deferrals, as we converted our existing backlog to revenue. As supply chain conditions have improved, and we have been able to increase shipment volumes and reduce lead times, our backlog decreased to $2.2 billion as of the end of the first quarter of fiscal 2024. We expect our backlog to continue to reduce during fiscal 2024 as supply chain conditions continue to improve and customers place fewer advanced orders. As that happens, we expect that our reliance upon securing quarterly book to revenue orders will grow, and that increased orders and a return to a more typical composition of our quarterly revenue will be a critical element of any future revenue growth.

The timing and degree to which we fulfill our backlog will have a significant impact on our revenue and can be affected by factors outside of our control, including customer readiness and willingness to receive shipment against existing orders. During fiscal 2023 and the first quarter of fiscal 2024, certain customers, including communications service providers and cable and multiservice operators in North America, that had earlier placed significant advanced orders, rescheduled deliveries for a portion of such orders. We believe that this was the result of a number of factors, including the rapid improvement in our delivery lead times as supply chain conditions improved and their capital expenditure and inventory levels. 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.

For additional information regarding our business, industry, market opportunity, competitive landscape, and strategy, see our 2023 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
Revenue and Currency Fluctuations
As a result of the reduction in orders relative to revenue described under “Overview” above, our revenue declined by 1.8% in the first quarter of fiscal 2024 as compared to the first quarter of fiscal 2023. In addition, during the first quarter of fiscal 2024, approximately 14.3% of our revenue was non-U.S. Dollar-denominated primarily including sales in Euros, Canadian Dollars, and British Pounds. During the first quarter of fiscal 2024 as compared to the first quarter of fiscal 2023, the U.S. Dollar primarily weakened against these currencies. Consequently, our revenue reported in U.S. Dollars slightly increased by approximately $3.4 million, or 0.3%, as compared to the first quarter of fiscal 2023, as a result of foreign exchange rates.

Quarter ended January 27, 2024 as compared to the quarter ended January 28, 2023
Networking Platforms segment revenue decreased by $47.9 million, reflecting product line sales decreases of $39.8 million of our Optical Networking products and $8.1 million of our Routing and Switching products.
Optical Networking sales decreased, primarily reflecting a sales decrease of $178.6 million of our 6500 Packet-Optical Platform, primarily to communications service providers. This sales decrease was partially offset by sales increases of $73.5 million of our 6500 Reconfigurable Line System (RLS) products and $64.5 million of our Waveserver® modular interconnect system, both primarily to cloud providers.

Routing and Switching sales decreased, primarily reflecting a sales decrease of $29.8 million of our virtualization software primarily to communications service providers, partially offset by sales increases of $11.0 million of our 3000 and 5000 families of service delivery and aggregation switches, primarily to cable and multiservice operators, $5.6 million of our platform independent software and $5.3 million of our 8100 Coherent IP networking platforms, both primarily to communications service providers.
Platform Software and Services segment revenue increased by $16.3 million, reflecting sales increases of $8.8 million of our software platforms and $7.5 million in our software maintenance services, both primarily for our Navigator NCS software platform.
Blue Planet Automation Software and Services segment revenue decreased by $1.5 million reflecting a sales decrease of $2.8 million in software platforms, partially offset by a sales increase of $1.3 million in professional software services, both primarily to communications service providers.
Global Services segment revenue increased by $14.3 million, primarily reflecting sales increases of $8.1 million of our installation and deployment services and $6.2 million of our maintenance support and training.

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 decrease in our Americas region revenue for the quarter ended January 27, 2024 was primarily driven by decreased sales in Canada and the United States. The decrease in our APAC region revenue for the quarter ended January 27, 2024 was primarily driven by decreased sales in India. The increase in our EMEA region revenue for the quarter ended January 27, 2024 was primarily driven by increased sales in the Netherlands.

The following table reflects our geographic distribution of revenue, principally based on the relevant location for our delivery of products and performance of services.

The decrease within our Networking Platforms segment primarily reflects a product line sales decrease of $34.3 million of Optical Networking products, which primarily reflects a sales decrease of $40.5 million of our 6500 Packet-Optical Platform, primarily to communication service providers.

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 cost 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 2023 Annual Report.

Quarter ended January 27, 2024 as compared to the quarter ended January 28, 2023
Gross profit increased by $11.0 million. Gross margin increased by 180 basis points, primarily due to reduced component costs and improved margins on Blue Planet software services, partially offset by a higher concentration of lower margin product mix.
Gross profit on products decreased by $8.1 million. Product gross margin increased by 120 basis points, primarily due to reduced component costs and higher software sales, partially offset by a higher concentration of lower margin product mix and higher inventory excess and obsolescence costs.
Gross profit on services increased by $19.1 million. Gross margin increased by 450 basis points, primarily due to improved margins on Blue Planet software services due to improved efficiencies on delivery. Additionally, margins on deployment services increased due to increased revenue and efficiencies reducing costs.

Operating Expense
Currency Fluctuations
Approximately 48.0% of our operating expense was non-U.S. Dollar-denominated during the first quarter of fiscal 2024, including expenses in Canadian Dollars, Indian Rupees, and Euros. During the first quarter of fiscal 2024, as compared to the first quarter of fiscal 2023, the U.S. Dollar fluctuated against these currencies. Consequently, our operating expense, net of hedging, reported in U.S. Dollars, was adversely affected by approximately $0.9 million, or 0.2%.
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 2023 Annual Report.

Quarter ended January 27, 2024 as compared to the quarter ended January 28, 2023
Interest and other income, net decreased by $21.3 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 in the first quarter of fiscal 2023, partially offset by higher interest income on our investments.
Interest expense increased by $7.9 million, primarily due to higher interest rates on our floating rate debt, net of hedging activity. For more information on our short-term and long-term debt, see Note 13 to our Condensed Consolidated Financial Statements included in Item 1 of Part I of this report.
Provision for income taxes decreased by $3.1 million, primarily due to the effect of research and development expenditures and tax credits. The effective tax rate for the first quarter of fiscal 2024 was higher than the effective tax rate for the first quarter of fiscal 2023, primarily due to the tax benefit of a gain on our cost method equity investment in the first quarter of fiscal 2023.

Liquidity and Capital Resources
Overview. For the three months ended January 27, 2024, we generated $266.1 million of cash in operating activities. Net income (adjusted for non-cash charges) provided approximately $136.1 million of cash and working capital provided approximately $130.0 million of cash. For additional details, see “Cash Provided By Operating Activities” below.

Cash, cash equivalents and investments increased by $225.6 million during the first three months of fiscal 2024. Cash from operations was partially offset by the following: (i) cash used for stock repurchases under our stock repurchase program of $38.2 million; (ii) cash used to fund our investing activities for capital expenditures totaling $16.6 million; and (iii) stock repurchases on vesting of our stock unit awards to employees relating to tax withholding of $10.1 million. In addition to cash provided by operating activities, proceeds from the issuance of equity under our employee stock purchase plan provided $16.9 million in cash during the three months ended January 27, 2024.
The following table sets forth changes in our cash, cash equivalents and investments in marketable debt securities for the periods indicated (in thousands):

Total cash, cash equivalents, and investments in marketable debt securities$1,475,291 $1,249,649 $225,642 

Principal Sources of Liquidity. Our principal sources of liquidity on hand include our cash, cash equivalents, and investments, which, as of January 27, 2024 totaled $1.5 billion, as well as the unused portion of the Revolving Credit Facility, to which we and certain of our subsidiaries are parties. The Revolving Credit Facility provides for a total commitment of $300.0 million with a maturity date of October 24, 2028. We principally use the Revolving Credit Facility to support the issuance of letters of credit that arise in the ordinary course of our business and for general corporate purposes. As of
31


January 27, 2024, letters of credit totaling $70.6 million were issued under the Revolving Credit Facility. There were no borrowings outstanding under the Revolving Credit Facility as of January 27, 2024.

Foreign Liquidity. The amount of cash, cash equivalents and short-term investments held by our foreign subsidiaries was $214.6 million as of January 27, 2024. Approximately $93.0 million of future cash generated from these foreign subsidiaries is expected to be repatriated with any remaining amount continuing to be indefinitely reinvested. A deferred tax liability related to the expected repatriation amount was accrued in fiscal 2023. There are no other significant temporary differences related to our investment in the foreign subsidiaries for which a deferred tax liability has not been recognized.
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 quarter of fiscal 2024, we repurchased an additional $32.0 million of our common stock under the stock repurchase program, and $218.0 million remained under the current repurchase authorization as of January 27, 2024. 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 16 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 Revolving 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.

Three Months Ended
January 27, 2024
Cash provided by accounts receivable$135,160 
Cash provided by inventories56,157 
Cash provided by prepaid expenses and other17,116

Cash provided by deferred revenue14,022 
Cash used in operating lease assets and liabilities, net(1,536)
 Total cash provided by working capital$130,004 

As compared to the end of fiscal 2023:

The $135.2 million of cash provided by accounts receivable during the first three months of fiscal 2024 primarily reflects increased cash collections and lower sales volume as compared to the fourth quarter of fiscal 2023;
The $56.2 million of cash provided by inventories during the first three months of fiscal 2024 primarily reflects the consumption of raw materials in excess of purchases, partially offset by increases in finished goods inventories from planned fulfillment of customer advance orders for which some deliveries have since been rescheduled as described in “Overview” above;

The $17.1 million of cash provided by prepaid expense and other during the first three months of fiscal 2024 primarily reflects lower non-trade receivables, upfront fees paid to customers and capitalized contract acquisition costs;
The $90.9 million of cash used in accounts payable, accruals, and other obligations during the first three months of fiscal 2024 primarily reflects the timing of payments to employees under our annual cash incentive compensation plans;
The $14.0 million of cash provided by deferred revenue during the first three months of fiscal 2024 represents an increase in advanced payments received on multi-year maintenance contracts from customers prior to revenue recognition; and
The $1.5 million of cash used in operating lease assets and liabilities, net, during the first three months of fiscal 2024 represents cash paid for operating lease payments in excess of operating lease costs.
Our days sales outstanding (“DSOs”) decreased from 103 for the first three months of fiscal 2023 to 88 for the first three months of fiscal 2024. The calculation of DSOs includes accounts receivables, net and contract assets for unbilled receivables, net included in prepaid expenses and other. Our inventory turns increased from 1.7 for the first three months of fiscal 2023 to 1.9 for the first three months of fiscal 2024.

Contractual Obligations

Our contractual obligations have not changed materially since October 28, 2023, except for the items listed below. For a summary of our contractual obligations, see Item 7 of Part II of the 2023 Annual Report.

Purchase Order Obligations. As of January 27, 2024 we had $1.9 billion in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory.

    The information set forth under the heading “Litigation” in Note 19 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 2023 Annual Report, including the information under “Risk Factors” in Item 1A of Part I thereof. 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 2023 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 the material factors that make an investment in our securities speculative or risky from those presented in our 2023 Annual Report.
If we are unable to secure order growth, our revenue may not reach the levels we anticipate.
As a result of unprecedented order volumes placed by customers to address supply chain constraints and longer delivery lead times, our backlog grew from $1.2 billion at the end of fiscal 2020 to $4.2 billion at the end of fiscal 2022. Our revenue grew by 21% during fiscal 2023 as we consumed a significant portion of this backlog. Customer order volumes rapidly decreased and, throughout much of fiscal 2023 and into the first quarter of fiscal 2024, we experienced orders that were below our revenue. As a result, our backlog decreased to $2.2 billion as of the end of the first quarter of fiscal 2024 and we expect it to continue to reduce during fiscal 2024. As backlog consumption reduces and represents a relatively smaller portion of our quarterly revenue, we expect to increasingly rely upon securing orders growth, particularly orders that we are able to convert into revenue during the same quarter in which they are received (which we refer to as "book to revenue"). Our future revenue growth will depend on securing increased orders, particularly from our service provider customers. Our failure to reach increased order levels, including a more typical composition of our quarterly revenue comprised of book to revenue orders, would adversely affect our revenue and results of operations.

The international scale of our sales and operations exposes us to additional risk and expense that could adversely affect our results of operations.
We market, sell and service our products globally, maintain personnel in numerous countries, and rely on a global supply chain for sourcing important components and manufacturing our products. Our international sales and operations are subject to inherent risks, including:
adverse social, political and economic conditions, such as continued inflation and rising interest rates;
effects of adverse changes in currency exchange rates;
greater difficulty in collecting accounts receivable and longer collection periods;
difficulty and cost of staffing and managing foreign operations;
higher incidence and risk of corruption or unethical business practices;
less protection for intellectual property rights in some countries;
tax and customs changes that adversely impact our global sourcing strategy, manufacturing practices, transfer-pricing, or competitiveness of our products for global sales;
compliance with certain testing, homologation or customization of products to conform to local standards;
significant changes to free trade agreements, trade protection measures, tariffs and other import measures, export compliance, economic sanctions measures, domestic preference procurement requirements, qualification to transact business and additional regulatory requirements;
natural disasters (including as a result of climate change), acts of war or terrorism, and public health emergencies, including the COVID-19 pandemic; and
uncertain economic, legal and political conditions in Europe, Asia and other regions where we do business, including, for example, as a result of continued impacts of Brexit on the relationship between the United Kingdom and Europe, the ongoing military conflicts between Russia and Ukraine and Israel and Hamas, including related maritime impacts in the Red Sea, and changes in China-Taiwan and U.S.-China relations.

We utilize a sourcing strategy that emphasizes global procurement of materials that has direct or indirect dependencies upon a number of vendors with operations in the Asia-Pacific region. We also rely upon third-party contract manufacturers, including those with facilities in Canada, Mexico, Thailand and the United States, to manufacture, support and ship our products. Physical, regulatory, technological, market, reputational, and legal risks related to climate change in these regions and globally are increasing in impact and diversity and the magnitude of any short-term or long-term adverse impact on our business or results of operations remains unknown. The physical impacts of climate change, including as a result of certain
35


types of natural disasters occurring more frequently or with more intensity or changing weather patterns, could disrupt our supply chain, result in damage to or closures of our facilities, and could otherwise have an adverse impact on our business, operating results, and financial condition.
Our international operations are subject to complex foreign and U.S. laws and regulations, including anti-bribery and corruption laws, antitrust or competition laws, data privacy laws, such as the GDPR, and environmental regulations, among others. In particular, recent years have seen a substantial increase in anti-bribery law enforcement activity by U.S. regulators, and we currently operate and seek to operate in many parts of the world that are recognized or perceived as having greater potential for corruption. Violations of any of these laws and regulations could result in fines and penalties, criminal sanctions against us or our employees, prohibitions on the conduct of our business and on our ability to offer our products and services in certain geographies, and significant harm to our business reputation. Our policies and procedures to promote compliance with these laws and regulations and to mitigate these risks may not protect us from all acts committed by our employees or third-party vendors, including contractors, agents and services partners or from the misinterpretation or changing application of such laws. Additionally, the costs of complying with these laws (including the costs of investigations, auditing and monitoring) could adversely affect our current or future business.
Our business, operations and financial results could also be adversely impacted by instability, disruption or destruction in a significant geographic region, including as a result of war, terrorism, riot, civil insurrection or social unrest; natural or man-made disasters; public health emergencies; or economic instability or weakness. For example, in February 2022, armed conflict escalated between Russia and Ukraine. The United States and certain other countries have imposed sanctions on Russia and could impose further sanctions, which could damage or disrupt international commerce and the global economy. We are complying with a broad range of U.S. and international sanctions and export control requirements imposed on Russia and, in March 2022, we announced our decision to suspend our business operations in Russia immediately. Although this decision did not materially impact our results of operations for fiscal 2022 or 2023 due to the limited amount of business that we conducted in Russia historically, it is not possible to predict the broader or longer-term consequences of this conflict, which could include further sanctions, export control and import restrictions, embargoes, regional instability, geopolitical shifts and adverse effects on macroeconomic conditions, security conditions, currency exchange rates and financial markets. In addition, the conflict between Israel and Hamas, and related regional impacts have recently resulted in damage to submarine cables in the Red Sea and disruption of networks using those cables, which could impact future projects by our customers in this region. Such geopolitical instability and uncertainty could have a negative impact on our ability to sell to, ship products to, collect payments from, and support customers in certain countries and regions based on trade restrictions, sanctions, embargoes and export control law restrictions, and logistics restrictions including closures of air space, and could increase the costs, risks and adverse impacts from supply chain and logistics challenges.
The success of our international sales and operations will depend, in large part, on our ability to anticipate and manage these risks effectively. Our failure to manage any of these risks could harm our international operations, reduce our international sales, and could give rise to liabilities, costs or other business difficulties that could adversely affect our operations and financial results.
