行業背景
網絡流量增長和容量需求增加
5

目錄表
我們銷售的市場是動態的,變化率很高。光網絡--通過對穿過光纜傳播的多個光的多個波長上的數字信息進行編碼來承載視頻、數據和語音流量--由於流量的增長,對增加帶寬的強勁需求。這種網絡流量增長是由一系列多樣化的通信服務以及基於雲的服務和應用程序推動的,這些服務通常需要企業和消費者最終用戶的按需服務級別:
基於雲的服務。 企業和消費者繼續通過採用一系列創新的基於雲的模型(包括平台即服務(Paaz)、軟件即服務(SaaS)和基礎設施即服務(IAID))以及不斷擴大的基於雲的服務範圍來取代本地計算和存儲,這些服務託管關鍵應用程序、存儲數據、支持查看和下載內容以及利用按需計算資源。此外,內容越來越多地轉移到網絡邊緣,從而產生了更接近用戶的新容量和流量需求。
過頂(「OTT」)服務和視頻流媒體. OTt內容是指通過第三方網絡從內容源直接向觀看者或最終用戶提供的視頻、多媒體和其他應用程序。隨着通過各種設備和媒體訪問的視頻內容的可用性和最終用戶對這些內容的需求的增加,流媒體和OTt服務的流量(包括高清和超高清視頻)也在擴大。
移動流量和第五代無線寬帶(「5G」)。 隨着智能手機和其他無線設備的持續普及,包括視頻、互聯網和數據服務在內的移動網絡應用程序的流量不斷擴大。由於大部分無線流量最終通過有線網絡到達目的地,移動通信的增長繼續對有線網絡提出更高的要求,包括從蜂窩站點發出的網絡的回程和前傳部分。5G技術進一步實現帶寬和性能的有意義的提高,並實現4G/LTE網絡無法支持的新興應用和服務。爲了充分利用這些機會,網絡運營商需要考慮5G技術對其有線基礎設施提出的要求。
住宅訪問應用程序和企業應用程序。 近年來,帶寬需求、流量模式和計算功能已向網絡邊緣轉移。COVID-19大流行大大加速了這一趨勢,包括遠程和混合工作、遠程學習和在家工作安排的增加。隨着更高比例的數據流集中在更靠近網絡邊緣,需要更大的容量和更高的帶寬到家庭和企業位置。這些轉變可能是永久性的,可能會影響網絡架構並要求網絡運營商進行適應。
基於光纖的接入網絡.有線電視和多業務運營商的網絡密集化計劃旨在將更多數字光纖推向更接近最終用戶的地方,以提高家庭和企業的潛在帶寬、計算能力和數據速度,同時降低電力、空間和運營成本。有線服務提供商正在通過將光纖延伸到家庭並深入接入網絡來響應類似的服務和最終客戶需求。
新興技術、服務和應用正在進一步影響或預計將影響網絡基礎設施,特別是在網絡邊緣,需要提高計算能力和自動化來滿足最終用戶所需的體驗質量。其中包括:
物聯網(「物聯網」).隨着設備和服務器之間網絡連接的增長,機器到機器相關流量(「M2M」)預計將佔流量的比例越來越大。這些連接允許共享可監控和分析的數據,包括智能電網應用、醫療保健和安全監控、資源和庫存管理、家庭娛樂、消費電器、互聯交通和其他M200萬數據應用。
沉浸式技術和超高清視頻(「UHD」)。 隨着這些技術的採用,虛擬現實(「VR」)、增強現實(「AR」)、交互體驗、遊戲和360°視頻以及UHD(0.4萬和8 K)視頻等沉浸式技術正在或可能對網絡提出進一步的容量需求。消費電子產品和其他科技公司正在迅速推進這些需要高帶寬和低延遲的應用,並使相關設備更廣泛地可用,消費者負擔得起。
邊緣計算.爲了爲最終用戶提供越來越多的沉浸式雲服務所需的體驗,網絡運營商已經增加並預計將繼續增加邊緣計算位置的數量和能力,以允許這些延遲敏感的工作負載在更接近用戶的地方進行處理。網絡邊緣的這些變化可能會影響網絡佈局、需求和流量模式。

機器學習(「ML」)和人工智能(「AI」)。 通過提高網絡智能和改進自動化,ML和AI可以改善網絡規劃、運營、用戶體驗和問題解決方案。隨着Iot的擴張和更多服務的創建,這些技術的採用預計將繼續增加,ML和AI預計將成爲進一步網絡流量和解決方案創新的驅動力,包括推動製造業、研發、機器人、安全、醫療保健和運輸等行業的帶寬需求。
生成人工智能(「Gen-AI」)。 近年來,Gen-AI平台經歷了前所未有的快速用戶採用,一系列引人注目的新產品在不同的用例中進入市場。雖然Gen-AI仍然是一個新興領域,並且可能會受到進一步的監管,但它爲企業和其他用戶提供了自動化任務、增強創造力和提高運營效率的重要機會。鑑於Gen-AI迄今爲止的採用軌跡,以及其對創新和生產力做出重要貢獻的潛力,Gen-AI可能會成爲未來數據中心內外網絡需求的重要刺激劑或加速器。
我們相信,這些技術、服務和應用程序的更多采用及其性能要求將進一步增加網絡流量,並對網絡基礎設施帶來額外的服務挑戰,要求網絡運營商投資於其城域、接入和聚合網絡以及核心網絡。
對更具可編程性和自動化網絡的需求
爲了爲最終用戶創造更加數字化的體驗、降低運營成本並引入更多的服務靈活性,網絡運營商正在投資下一代基礎設施,將端到端服務自動化與高度可編程基礎設施的部署相結合。我們預計網絡運營商將繼續追求更好地利用分析和控制能力的策略,以實現閉環自動化。閉環自動化是可編程網絡基礎設施和軟件控制元件之間的連續通信循環,用於分析網絡條件、流量需求和資源可用性,以確定流量或網絡功能的最佳放置,以提供最佳服務質量和資源利用率。
我們相信,這些策略的採用,以及核心、城域、聚合和接入網絡基礎設施的相關發展,將需要網絡運營商及其網絡解決方案供應商越來越多地尋求利用物理和虛擬網絡資源的生態系統,並通過軟件進行優化。我們預計,這些網絡架構方法反過來將需要網絡解決方案供應商之間更大程度的合作、協作和互操作性。
設計和採購網絡基礎設施解決方案的不同方法
網絡運營商在網絡基礎設施解決方案的設計和採購中正在尋求各種方法或「消費模式」。除了從同一供應商購買包括硬件、軟件和服務在內的完全集成的網絡解決方案外,新的消費模式還包括採購或使用:
來自一個供應商的完全集成的基礎設施解決方案,單獨使用網絡運營商自己的軟件或另一個供應商的軟件;
具有來自一個供應商的開放接口以及從不同供應商單獨或「分散」採購調制解調器技術的集成光線路系統;
與集成的專有第三方軟件解決方案一致或作爲其替代方案的開源軟件;
在現成的第三方設備上運行的開放IP網絡操作系統;以及
系統集成服務或客戶自我集成以重建分解的組件。
一些網絡運營商,包括我們的某些最大客戶,已經採用或正在尋求開發和使用已發佈的參考設計和開源規範,以採購現貨或商品化硬件(通常稱爲「白盒」硬件)。這種商品化硬件可以與內部開發的數據路徑和控制軟件或第三方開發的網絡操作軟件一起使用。此外,一些網絡運營商正在推行強調部署更小形狀的可插入調制解調器技術的網絡策略,該技術可以容納在交換機或路由器平台中,或代替傳統光學系統中的調制解調器使用。
最終出現的消費模式及其採用程度將在很大程度上取決於某些網絡運營商的情況和策略。雖然迄今爲止,這些方法的採用受到限制,但我們預計客戶對各種消費模式的持續考慮將需要網絡運營商和供應商評估並可能隨着時間的推移擴大他們的產品和商業模式,從而賦予供應商提供一系列網絡解決方案的能力以最大的靈活性和選擇。

我們定期審查現有的解決方案產品以及新功能、組件或產品的預期開發,以確定它們是否適合我們的產品組合和更廣泛的企業戰略。我們還評估市場需求、技術演變、預期投資回報和增長機會,以及開發和支持這些產品所需的成本和資源。爲了確保我們的產品開發投資和解決方案提供與市場需求緊密一致,我們不斷尋求客戶的意見並促進產品開發、營銷和銷售組織之間的合作。在某些情況下,當我們尋求利用或獲得補充或
13

目錄表
新興技術或解決方案,我們可能會通過收購或根據技術許可證、OEM安排和其他戰略技術關係或投資通過與第三方的舉措來獲得技術。此外,我們還參與行業和標準組織,並在適當的情況下將來自這些附屬機構的信息納入整個產品開發過程。
全球客戶參與
我們的全球客戶參與組織包括直接和間接銷售、系統工程和服務機構,圍繞以下地區和客戶類型進行組織:(i)美國、加拿大、加勒比海和拉丁美洲(「美洲」);(ii)「國際」,包括歐洲、中東和非洲(「EMEA」)以及亞太地區、日本和印度(「亞太地區」);和(iii)全球雲和內容網絡客戶,包括雲提供商、內容和數據中心公司。在每個重點領域,我們都維持着專注於特定地區、國家、客戶或市場垂直領域的特定團隊或人員。這些團隊包括銷售管理、客戶銷售人員和銷售工程師,以及合作伙伴資源、現場營銷、服務專業人員和商業管理人員,他們確保我們與客戶保持密切接觸的諮詢關係。
我們還維持着全球合作伙伴計劃,其中包括分銷商、經銷商、系統集成商、服務提供商、原始設備製造商、原始設計製造商以及營銷和銷售我們產品和服務的其他第三方分銷商。我們利用這些第三方渠道合作伙伴向特定地區、應用程序或客戶垂直領域營銷和銷售我們的解決方案。我們相信,有機會利用這些關係來擴大我們的潛在市場,同時降低進入其他市場的財務和運營風險。對於Ciena合作伙伴網絡中的第三方,我們維護了我們網站上提供的行爲準則,該準則闡述了我們對他們在支持我們業務時要求他們遵守的高標準道德和合法合規行爲的期望。
爲了支持我們的全球客戶參與工作,我們投資營銷活動,以產生對我們產品和服務的需求。我們的營銷策略高度專注於建設我們的品牌以創造客戶對Ciena的偏好,參與思想領導力計劃以說明我們的創新如何解決客戶業務問題,並使我們的銷售團隊能夠推動客戶採用我們的解決方案。我們的營銷團隊通過各種活動支持我們的銷售工作,包括直接客戶互動、基於帳戶的營銷活動、投資組合營銷、行業活動、媒體關係、行業分析師關係、社交媒體、貿易展、我們的網站和其他營銷工具爲我們的客戶和渠道合作伙伴。
運營和供應鏈管理
我們產品的大部分製造都是通過第三方合同製造商進行的。我們的運營人員管理與這些第三方製造商和全球供應鏈的關係,解決零部件採購、製造、產品測試和質量以及與我們產品的分銷和支持相關的履行和物流問題。
我們採用一種採購戰略,傳統上強調全球採購材料和在勞動力成本較低的地區製造產品。我們依賴第三方合同製造商,包括那些在加拿大、墨西哥、泰國、印度和美國設有工廠的製造商來製造、支持和運輸我們的產品,因此面臨與其業務、財務狀況和經營地理位置相關的風險,包括政治風險、涉及這些國家的稅收和貿易政策的變化,以及包括氣候變化影響在內的物理風險。我們還依賴合同製造商和其他第三方進行設計和原型開發、零部件採購、全面生產、最終組裝、測試和分銷業務。我們的製造商和零部件分銷合作伙伴根據我們的規格、批准的供應商名單、材料清單以及測試和質量標準來採購組裝和製造我們產品所需的零部件。我們的製造商和零部件分銷合作伙伴的活動是基於我們向他們提供的滾動預測,以估計對我們產品的需求。我們與這些合作伙伴和我們的供應商密切合作,管理材料、質量、成本和交貨時間,並不斷評估他們的服務,以確保在可靠和具有成本效益的基礎上實現性能。一般來說,我們與供應商和合同製造商的協議是框架協議,我們根據這些協議下達採購訂單,不承諾長期批量採購。
我們目前使用分銷合作伙伴來履行和交付我們的產品。我們相信,我們的採購、製造和分銷策略使我們能夠節省資本、降低產品銷售成本、快速適應市場需求的變化,並且無需將大量資源投入製造相關工廠和設備即可運營。
我們繼續專注於一系列旨在優化我們的運營、提高我們的彈性並推動降低成本和提高效率的舉措。我們的努力包括流程優化計劃,例如供應商管理的庫存,以及旨在提高採購、生產、物流和履行效率的其他運營模式和策略。

目錄表
爲了提高運營效率和現代化我們的供應鏈運營,同時在不斷變化的市場條件下推動長期可持續發展和彈性,我們正在開展一系列數字技術轉型工作,包括高級分析、自動化和其他數字解決方案。我們定期評估和監控供應鏈風險,並實施了各種策略來緩解這些風險並增強彈性。這些措施包括雙重採購戰略、庫存管理計劃以及與主要供應商的持續合作,以確保透明度並與我們的目標保持一致。
我們積極與第三方供應商和業務合作伙伴合作,在全球供應鏈中促進社會責任的商業實踐。爲此,我們採用了責任商業聯盟(「RBA」)行爲準則中規定的原則。澳大利亞央行行爲準則制定了標準,旨在確保電子行業或電子產品爲關鍵組成部分的行業的工作條件,其供應鏈安全,工人受到尊重和尊嚴,業務運營對環境負責並符合道德規範。我們推廣這些原則,並要求我們的供應商同意遵守這些相同的標準。我們還發布可持續發展報告並維護適用於供應商的人權政策,其中每項政策都包含有關我們促進負責任商業實踐努力的更多詳細信息。
季節性
我們歷來經歷過客戶活動在訂單和收入方面的季節性季度波動,特別是與服務提供商客戶的季節性波動。隨着這些客戶的採購週期放緩和網絡部署活動減少,我們在接近日曆年末的時候經歷了訂單量的減少。這段時間恰逢我們財政年度的第一季度。我們訂單流中的這種季節性通常會導致我們財年第一季度的收入低於上一季度。這些季節性影響可能不會在未來期間持續適用,也可能不是我們未來收入或運營結果的可靠指標。我們最近經歷的動態供需環境的影響,加上我們增加的積壓,已經並可能繼續影響我們業務的傳統季節性。此外,雲提供商客戶佔我們收入的百分比的增長也可能在未來改變這種模式,這些客戶不一定遵循相同的季節性訂購模式。關於當前供需環境和我們的積壓情況的更詳細討論,見本報告第二部分項目7「管理層對財務狀況和業務成果的討論和分析--概覽」。
競爭
在全球範圍內,網絡解決方案供應商之間的競爭依然激烈。我們競爭的市場的特點是技術迅速進步,新解決方案頻繁推出,以及積極的銷售努力,包括利用巨大的定價壓力取代現有供應商並奪取市場份額。包括我們的網絡平台和平台軟件和服務在內的網絡解決方案的銷售競爭由少數超大型跨國公司主導。我們的競爭對手包括諾基亞、華爲(定義如下)、思科、瞻博網絡和中興通訊。與我們相比,這些競爭對手中的許多公司擁有更多的財務、運營和營銷資源,提供更廣泛的產品,並與服務提供商和其他細分客戶建立了更好的關係。由於它們的規模和資源,它們可能被認爲更適合大型網絡運營商的採購或網絡戰略。我們還繼續與幾家規模較小但成熟的公司競爭,這些公司提供一種或多種產品,直接或間接與我們的產品競爭,或者其產品針對我們所針對的市場和客戶群中的特定利基市場。這些競爭對手包括英飛朗、Ribbon Communications、Calix、Adtran、DZS和Ekinop。我們還與許多公司競爭,這些公司爲特定的產品、應用、服務、客戶群或地理市場提供顯著的競爭。

跟上市場對技術創新的需求需要相當的研發投資能力。因此,我們的一些競爭對手,無論大小,都選擇依賴由第三方提供商開發和採購的元件和模塊技術,包括NTt電子、Marvell Technology Group和思科。我們可能會與這些提供商競爭,要麼間接地因爲他們的技術是我們競爭對手的關鍵使能技術,要麼是「白盒」技術等替代消費模式,要麼直接在模塊、可插入和組件銷售機會中競爭。
隨着我們推進我們的企業戰略並尋求更多客戶採用我們的藍色星球自動化軟件,我們預計將與軟件供應商和傳統IT服務供應商進行更直接的競爭。我們藍色星球自動化軟件的競爭對手包括思科、諾基亞、Amdocs、Netcracker和愛立信。
在我們的市場和細分市場中,主要的競爭因素包括:
網絡解決方案的功能、速度、容量、可擴展性和性能;
滿足業務需求並推動成功成果的能力;
15

目錄表
性能價格、每位成本和網絡解決方案的總擁有成本;
現有業務關係的有效性和強度;
技術路線圖和前瞻創新能力,包括在研發上投入大量資金的能力;
交付產品和功能的上市時間;
公司穩定和財務健康;
能夠提供全面的網絡解決方案,包括硬件、軟件和服務;

服務和支持能力;
企業、產品開發、支持流程和產品的安全;
網絡解決方案的空間要求和功耗;以及
能夠提供解決方案,幫助客戶管理其網絡的生命週期影響並實現其氣候可持續發展目標。

我們的競爭格局已經並可能繼續受到國際貿易和相關問題的影響,特別是美國和中國之間的貿易。例如,2019年5月,美國商務部修改了《美國出口管理條例》(EAR),將華爲技術有限公司(華爲)及其某些附屬公司添加到違反美國國家安全和外交政策利益的實體名單中,導致對向華爲出口、再出口和轉讓美國受監管的技術和產品產生了新的重大限制。2020年8月,美國商務部在實體名單中增加了更多華爲關聯公司,確認適用於華爲的臨時通用許可證到期,並在耳邊修改了外國直接產品規則,大幅擴大了對華爲的適用範圍。另外,美國已經採取措施,限制聯邦機構與華爲和中興做生意,並限制美國無線運營商使用聯邦補貼從華爲和中興購買設備。美國也鼓勵其他國家的政府考慮類似的限制措施。這些行動導致美國和中國之間的緊張關係升級,並導致中國的報復,並帶來了中國政府可能採取進一步措施報復美國行業或公司的風險。
我們還預計,隨着網絡運營商追求多元化的網絡策略和消費模式,我們行業的競爭將繼續擴大和加劇。隨着這些變化的發生,我們預計我們的業務將與其他網絡解決方案供應商更直接地重疊,包括IP路由器供應商、數據中心交換機提供商以及傳統上面向不同網絡應用、層或功能的其他網絡技術供應商或集成商。我們還可能面臨來自系統和組件供應商的競爭,包括我們供應鏈中的供應商,他們開發可插入調制解調器技術或基於現成或商品化硬件技術的其他網絡產品,稱爲「白盒」硬件,特別是當客戶的網絡策略試圖強調此類產品的部署或採用分類方法來採購硬件和軟件。
專利、商標和其他知識產權
我們業務和技術領導地位的成功在很大程度上取決於我們的專有和內部開發的技術。我們依靠專利、版權、商標和商業祕密法提供的知識產權保護來建立、維護和執行我們專有技術和產品品牌的權利。我們定期提交專利申請,並在美國和我們開展業務的其他國家擁有大量專利。截至2023年12月1日,我們在全球擁有約2,100項已授權專利和650多項正在審批的專利申請。
強制執行專有權,尤其是專利,可能成本高昂,而且我們無法確定我們正在採取的步驟將檢測、防止或最大限度地降低所有未經授權使用的風險。我們所競爭的行業的特點是技術瞬息萬變、專利數量龐大、有關專利和其他知識產權的索賠和相關訴訟頻繁。我們受到多項與專利侵權相關的索賠,並被要求根據與第三方提出的侵權索賠相關的合同賠償義務向客戶進行賠償。知識產權侵權主張可能會導致我們承擔巨額費用,包括爲相關行動辯護的和解費用和法律費用。如果我們不能成功捍衛這些主張,我們的業務可能會受到不利影響。
我們的操作系統軟件、平台軟件、藍色星球自動化軟件和其他解決方案結合了獲得第三方許可的軟件和組件,包括受各種開源軟件許可的軟件。未能獲得或維護此類許可或其他第三方知識產權可能會影響我們的開發工作

和市場機會,或者可能需要我們重新設計我們的產品或獲得替代技術。此外,開源和其他技術許可證可能會被解釋爲對我們產品商業化的能力施加意想不到的條件或限制的風險。
環境和可持續性
2023年,我們制定了新的環境目標,這些目標已獲得「基於科學的目標」倡議的批准,並將我們的脫碳努力與《巴黎氣候協定》保持一致,以將全球變暖限制在比工業化前水平高1.5攝氏度。我們的環境戰略涉及持續創新我們的產品和服務,以幫助減少電力、空間和材料,提高運營效率以減少我們的業務對環境的影響,與我們的供應商和其他業務合作伙伴的參與和協作,以及促進員工體驗,讓我們的員工參與可持續發展。
我們的產品和產品開發工作旨在改善我們的解決方案空間和電力要求,爲我們的客戶創建更高效、更可持續的網絡,並實現他們的氣候雄心。我們通過努力提高網絡解決方案中每千兆吞吐量的能源效率,以及減少運營網絡所需網絡元件總數的舉措來促進環境可持續發展。我們尋求機會來最大限度地減少產品設計中的資源影響,並管理產品的生命週期影響,包括包裝和分銷、支持以及報廢再利用、翻新和回收。我們自願每年提供DPP氣候變化和水資源披露,並且是澳大利亞央行的成員。我們尋求確保我們的主要直接供應商採用澳大利亞央行行爲準則中規定的標準和原則。
人民和文化
截至2023年10月28日,我們的技術解決方案由才華橫溢的人才開發、營銷、銷售和支持,我們的全球員工隊伍共有8,483名,其中超過98%是全職員工。我們在超過38個國家/地區擁有廣泛的人才基礎,其中約57%在美洲,35%在亞太地區,8%在歐洲、中東和非洲地區,其中大多數從事工程、運營或銷售工作。
我們相信,我們的行業和創新領導力最終植根於人。技術領域對合格人才的競爭非常激烈,我們的成功在很大程度上取決於我們招募、培養和留住高效且敬業的勞動力的能力。因此,投資於員工及其福祉、提供有競爭力的薪酬和福利以及採用先進的人力資本管理實踐構成了我們企業戰略的核心要素。
我們的董事會負責監督我們的企業戰略,其中包括管理層對我們「人員戰略」的設計和執行。該戰略旨在確保我們繼續吸引和保留執行業務計劃所需的人才,並且我們擁有與這些目標保持一致並支持這些目標的計劃、舉措、獎勵和認可。通過我們的「人員承諾」,我們促進了一個工作場所環境,讓我們的員工獲得賦權、感受到被包容的感覺,並有機會通過在Ciena的工作做出改變。在此過程中,我們尋求爲員工培養一種充滿活力、歸屬感和幸福的文化,使我們能夠成爲市場中有吸引力的首選僱主。我們的高管團隊積極參與並贊助旨在促進這種企業文化的關鍵舉措和員工資源小組。爲此,我們的人才戰略重點關注以下方面:
促進多元、包容和公平的文化。我們通過招聘外展、內部網絡和資源小組、包容性網絡和指導計劃,促進一個包容和多樣化的工作場所,所有個人都受到尊重,並感到自己屬於哪裏,無論他們的年齡、種族、國籍、性別、宗教、殘疾、性取向或性別認同。我們還維持着一個全球包容性理事會,該理事會由我們的兩名高管領導,旨在解決包容性行動,我們已經簽署了首席執行官促進多樣性和包容性行動。截至2023年10月28日,我們的全球勞動力約爲21.6%的女性。我們的董事會30%是女性,20%是種族多元化。截至2022年12月31日,在我們總部所在的美國,我們的1,890名員工大約反映了以下種族:64.2%的白人,21.9%的亞洲人,6.2%的西班牙裔或拉丁裔,5.0%的黑人或非裔美國人,2.2%的兩個或更多種族(不是西班牙裔或拉丁裔),以及0.5%的額外群體(包括美國印第安人、阿拉斯加原住民、夏威夷原住民或其他太平洋島民)。我們定期監測我們的招聘過程,以提高我們勞動力和應聘者庫的多樣性,並繼續提供有意識的包容性研討會,以加深我們不同群體的理解。此外,我們還支持多個活躍的內部網絡和資源小組,包括Ciena組的女性、Ciena組的黑人和非洲遺產、Ciena組的Latinx、Ciena組的亞洲人、Ciena組的Pride、Ciena組的獸醫和Ciena早期職業小組的Next。在2023財年,我們繼續實施有針對性的發展計劃,旨在加強

支持員工幸福感和敬業度。我們優先支持我們員工及其合格家屬的整體福祉。我們提供廣泛而多樣的計劃,專注於身體、精神和情感、財務和社會健康,並擴大了我們的服務範圍,將重點放在關鍵的生活事件上,如老齡化和退休準備。我們的福利計劃通過各種方式部署,包括費用報銷福利、福利挑戰和獎勵、全天候危機支持、員工援助資源、心理健康培訓,以及參與者可以通過數字和託管網絡研討會訪問的資源庫。我們定期通過員工參與度和脈搏調查徵求員工對特定問題的意見,這些調查旨在評估我們在促進支持員工承諾和衡量我們的合規文化的環境方面的成功程度。我們的2023財年員工敬業度調查參與率約爲84%,敬業度得分超過行業基準。我們的全球福利計劃還包括在我們許多地區實行遠程靈活的工作安排和靈活的帶薪休假的長期做法。
提供有競爭力的薪酬,確保薪酬公平。我們努力確保我們的員工獲得有競爭力、公平和透明的薪酬,並提供累進的福利。我們對全球性別和美國的種族進行年度薪酬公平評估,並採取行動確保我們公平地向從事類似工作的個人支付薪酬。我們從2020財年開始部署Syndio的工作場所公平平台,以微調我們的方法並實現定期的全球薪酬公平評估。爲了使業績和股東利益保持一致,我們將年度激勵性薪酬同時基於業務和個人業績,我們維持員工股票購買計劃,近年來我們廣泛擴大了員工對股權薪酬的參與。我們還提供全面的家庭假,包括在各個生活階段爲員工提供支持的全球家庭假、護理員假、喪假、育兒假,其中包括新媽媽最少18周的帶薪假期(包括8周的康復和10周的陪伴),以及新父親和養父母的10周帶薪假期,以及爲養父母提供的經濟援助,最近還將彈性帶薪假期擴大到全球98%以上的員工。我們提供有意義的退休福利和計劃,以促進員工的退休準備。近年來,我們加強了對我們北美退休計劃的僱主繳費,爲員工增加了第一個ESG基金選項,截至2023年10月28日,美國和加拿大符合條件的員工參加我們的固定繳款退休計劃的比例超過99%。
提供員工認可計劃。 我們還爲員工提供獎勵和表彰計劃,包括同行和管理層發起的獎項,以表彰取得顯着成就和最能體現我們核心價值觀的員工,以及專利激勵和傑出工程師獎。我們相信,提供這些認可計劃有助於推動員工表現出色。
爲增長和發展創造機會。截至2023年10月28日,我們約有20.9%的員工年齡在30歲及以下,51%的員工年齡在31歲至50歲之間,28.1%的員工年齡在51歲及以上。我們專注於在職業生涯的各個階段爲員工的成長、發展、培訓和教育創造機會。我們提供從公司內部培養人才和確定新職位候選人的機會,並提供職業早期和新畢業生網絡和發展計劃、管理和領導力發展計劃、教練和指導計劃,以及通過學費報銷爲繼續教育提供支持。我們運行領導層繼任規劃流程,旨在培養和留住關鍵人才,並確保關鍵角色的業務連續性。我們最近還啓動了一項計劃,以確定整個組織中被確定爲具有未來增長和發展潛力的個人,以便在職業生涯早期培養這些人才,以適應未來的領導角色。
促進社區外展和支持。 我們相信,通過我們生活和工作的社區的企業捐贈、慈善配對和員工志願服務來回饋和促進社區外展和支持非常重要。通過我們的「Ciena Cares」社區計劃,我們提供員工慈善捐款的企業匹配、工作時間靈活的志願服務以及員工可以將服務時間捐贈給他們選擇的慈善機構的企業獎勵。我們的數字包容性計劃旨在動員我們的全球勞動力,利用我們的創新領導地位,並與客戶、供應商和其他合作伙伴合作,幫助彌合數字鴻溝。通過這一舉措,我們資助了一些項目,通過提供更好的連接性、獲得使能技術和數字技能發展來支持全球社區中服務不足的學生。
促進強大的道德商業文化。 我們相信,對良好的公司治理和最高的道德標準的承諾對於我們的長期成功至關重要,我們致力於向員工灌輸

恪守誠信和商業道德。我們維護商業行爲和道德準則,爲Ciena的董事、高級管理人員和員工設定行爲標準。所有員工都需要完成關於我們的商業行爲和道德準則的培訓,我們針對我們的商業行爲和道德準則定期進行員工確認,並定期進行與其中包含的特定主題相關的培訓和溝通。此外,我們還擁有一個企業合規委員會,在整個Ciena範圍內促進誠信和合規領導,並設有專門關注合規和道德的專門職能。我們還保留了幾種易於訪問的內部和外部方法,通過這些方法,我們的員工、業務合作伙伴和投資者可以報告與我們業務的道德運營相關的擔憂,包括在允許的情況下匿名報告。我們對所有員工進行了關於我們的合規計劃和誠信文化的調查,以評估和加強我們的文化和做法,並在2022財年收到了大約69%的員工對這些調查的反饋。
政府法規
環境問題
各個司法管轄區的環境法規都在加強,我們預計我們的國內和國際業務可能會受到額外的環境合規要求的約束,這可能需要我們產生額外的成本。到目前爲止,我們的合規行動和與環境法規相關的成本尚未對我們的資本支出、收益或競爭地位產生重大成本或影響。本公司的業務及營運目前受世界各地不同司法管轄區的環保法律規管,包括歐洲聯盟(下稱「歐盟」)通過的「廢棄電器及電子設備」(WEEE)及「限制在電器及電子設備中使用某些有害物質」(「RoHS」)規例。我們還受到適用於我們產品或供應鏈中存在的「衝突礦物」的披露和相關要求的約束。我們尋求遵守與我們產品的材料和內容以及產品回收和回收相關的適用法律來運營我們的業務,並擁有幫助我們解決這些法律的計劃、政策和客戶產品。
其他條例
作爲一家擁有全球業務的公司,我們受到複雜的外國和美國法律法規的約束,包括貿易法規、關稅、進出口法規、反賄賂和腐敗法、反壟斷或競爭法、數據隱私法律和法規,如歐盟一般數據保護法規(GDPR)、網絡安全法律法規和環境法規等。我們已經制定了促進遵守這些法律和法規的政策和程序。到目前爲止,我們的合規行動以及與這些法律、規則和法規相關的成本尚未對我們的資本支出、收益或競爭地位產生重大成本或影響。政府法規可能會發生變化,因此,我們無法評估遵守未來要求可能產生的影響,也無法評估我們遵守這些法規是否會對我們未來的業務產生重大影響。有關政府法規如何影響我們業務的進一步討論,請參閱「風險因素-與知識產權、訴訟、法規和政府政策相關的風險」中的相關討論。

項目1A.危險因素
投資我們的證券涉及高度風險。除了本報告中包含的其他信息外,您在投資我們的證券之前還應考慮以下風險因素。
與我們的業務和行業相關的風險
我們的積壓可能不能準確反映我們未來收入的水平和時間。
由於供應鏈限制和更長的交貨提前期推動了前期訂單量的增長,我們的積壓訂單從2020財年末的12億美元增加到2022財年末的42億美元。隨着供應鏈條件的改善,我們能夠增加出貨量並縮短交貨期,2023財年末我們的積壓訂單減少到26億美元。然而,我們的訂單量在2022財年第四季度開始放緩,2023財年我們的訂單繼續低於收入。我們預計,我們在2021財年和2022財年較早時期經歷的非常高的訂單水平不會恢復或長期持續。雖然我們預計訂單量將隨着時間的推移而正常化,但我們預計2024財年我們的積壓訂單將繼續減少。由於客戶計劃或供應鏈限制導致的延遲,可能會在收到採購訂單後的幾個季度內完成積壓。一般來說,我們的客戶可以在事先通知有限的情況下取消、延遲交貨或更改他們的訂單,或者他們可能決定不接受我們的產品和服務,儘管取消和拒絕接受的情況在歷史上很少見。積壓還包括可能與多年支持期相關的某些服務義務。因此,積壓不一定被視爲任何特定時期未來收入的準確指標。

我們的收入、毛利率和經營業績可能會出現明顯且不可預測的季度波動。

我們的收入、毛利率和運營結果可能會在每個季度之間出現不可預測的顯著波動。我們的預算支出水平是基於我們對客戶支出計劃的可見性以及我們對未來收入和毛利率的預測。客戶支出水平的可見性可能不確定,支出模式可能會發生變化,降低我們的支出水平可能需要大量時間才能實施。從歷史上看,我們季度收入的很大一部分來自同一季度收到的客戶訂單(我們將其稱爲「賬面收入比」),因此較難預測,並受季度訂單低於預期的影響。然而,在2022財年,我們產生了大量積壓的客戶訂單,在2023財年上半年,我們的收入受到供應可用性以及客戶推遲交付現有積壓訂單的更大影響。具體地說,在2023財年,某些客戶,包括北美的通信服務提供商和有線電視和多服務運營商,以及早先下了大量預訂單的雲提供商,重新安排了部分此類訂單的交付時間,以滿足其資本預算和業務吸收此類庫存的能力。我們預計2024財年我們的積壓將繼續減少。隨着時間的推移,我們預計我們對確保季度賬面收入比的依賴將會增長,這些訂單將代表我們季度收入中更典型的構成。然而,在這些動態中,我們對特定時期的結果可能很難預測。這些動態以及包括下述因素在內的一系列因素可能會對季度收入、毛利率和經營業績產生重大不利影響:

客戶的支出水平或網絡部署計劃發生變化,特別是對於我們的服務提供商和雲提供商客戶;
訂單時間和數量,包括圖書收入訂單;
銷售收入確認的時間,特別是與大額訂單相關的時間;
零部件和製造能力的可用性;
裝運和交付時間,包括任何交付延遲;
積壓水平;
我們行業的競爭水平和定價壓力;
我們在市場上經常遇到的價格侵蝕的速度和影響;
維持在職或確保與關鍵客戶獲得新機會所需的商業特許權或不利商業條款的影響;
任何特定季度按產品細分、地理位置和客戶劃分的收入組合;
我們在實現有針對性的成本降低和供應鏈效率提高方面的成功程度;
我們產生的啓動成本,包括支持初始部署、獲得新客戶或進入新市場所需的項目利潤率較低的階段;
我們在進入新市場和獲得新客戶方面的成功程度;
影響對我們產品和服務或客戶產品和服務的需求的長期和短期變化行爲或客戶需求;
基於技術的價格壓縮以及我們推出的新平台,以提高性能價格;
23

目錄表
不斷變化的市場、經濟和政治條件,包括關稅和其他貿易限制的影響或退出或實質性修改國際貿易協定的努力;
我們無法控制的因素,例如自然災害、氣候變化、戰爭或恐怖主義行爲以及公共衛生緊急情況,例如COVID-19大流行;
我們客戶和供應商的財務穩定性;
我們的客戶、供應商和競爭對手之間的整合活動;
安裝服務的可用性和客戶站點的準備情況;
外匯的不利影響;和
我們業務中的季節性影響。

由於這些因素和其他條件影響我們的業務和經營業績,我們認爲我們的經營業績的季度比較並不一定是未來業績的良好指標。上述因素和其他因素的季度波動可能會導致我們的收入、毛利率和運營業績相對於我們的指導、長期財務目標或財務分析師或投資者的預期表現不佳,這可能會導致我們的股價波動或下跌。

與供應鏈動態(包括半導體元件)相關的挑戰可能會對我們的增長、毛利率和財務業績產生不利影響。
面對一系列行業的需求,全球對某些原材料和零部件的供應,特別是半導體、集成電路和我們大多數產品中使用的其他電子零部件的供應,在最近幾個時期經歷了很大的限制和中斷。因此,我們經歷了嚴重的零部件短缺、交貨期延長、成本增加,以及我們供應商基礎上先前承諾的關鍵零部件供應意外取消或延遲。雖然供應的可靠性有所改善,但交付期延長和零部件成本上升可能會繼續對我們的收入、銷售商品成本以及我們以與前幾個時期一致的方式降低生產成本的能力產生不利影響。目前尚不清楚供應環境何時會完全穩定,以及它將對我們的業務和未來一段時間的運營結果產生什麼影響。此外,目前的地緣政治趨勢可能會影響零部件的供應,對關鍵礦物以及半導體技術和芯片的某些相關出口管制可能會限制供應,並對此類零部件的交付和開發產生不利影響。這種波動已經並可能進一步影響組件的可用性、交付期和成本,這可能會對我們的收入和客戶的購買決策產生不利影響。爲了應對這些風險,我們實施了緩解戰略,包括擴大製造能力、實施多來源活動、鑑定替代部件和重新設計產品;然而,這些努力可能無法減少不利供應鏈狀況的影響。供應鏈挑戰還可能影響客戶滿意度或未來與客戶的業務機會,並導致現金使用量增加、工程設計更改和新產品推出延遲,每一項都可能對我們的業務和財務業績產生不利影響。

少數客戶佔我們收入的很大一部分。其中一個或多個客戶的流失或其支出的大幅減少可能會對我們的業務和運營業績產生重大不利影響。

我們很大一部分收入集中在一小部分客戶身上。例如,我們的十大客戶貢獻了我們2023財年收入的53.7%和2022財年收入的56.3%。從歷史上看,我們收入最高的客戶主要是大型通信服務提供商。例如,雲提供商客戶約佔我們2023財年收入的12.8%,AT&T約佔我們2023財年收入的10.6%,佔我們2022財年收入的11.9%,Verizon約佔我們2022財年收入的11.1%。由於近年來努力使我們的業務多樣化,構成我們客戶基礎和收入最高客戶的客戶細分和地理位置發生了變化。在2023財年,我們的十大客戶中有四家雲提供商。雲提供商客戶通過我們對他們的直接銷售(包括數據中心互聯)以及他們對其他網絡運營商購買的間接影響,一直是我們收入的重要貢獻者。因此,我們的財務業績和業務增長能力與相對較少的客戶的支出密切相關。我們的業務和運營結果可能會因這些客戶群內部或外部的大客戶流失,以及支出或資本支出預算的減少、網絡部署計劃的變化或我們最大客戶購買網絡解決方案的消費模式的變化而受到重大不利影響。
通信服務提供商和有線電視運營商開展了大量的橫向和縱向整合活動。客戶整合可以提高客戶購買力,過去曾因戰略或領導層的變化、監管批准的時間以及此類交易導致的高水平債務而導致網絡支出延遲或減少。

由於我們的收入集中在通信服務提供商和雲提供商,我們的業務和運營結果可能會受到市場、行業、監管或競爭動態的重大影響,對這些客戶群產生不利影響。例如,隨着雲服務運營商、OTT提供商和其他內容提供商繼續挑戰其傳統業務模式和網絡基礎設施,通信服務提供商繼續面臨快速變化的競爭格局。過去,這些動態對我們某些最大的服務提供商客戶的網絡支出水平產生了不利影響。其中包括AT&T在內的幾家公司已經宣佈了各種舉措,試圖改變他們購買網絡基礎設施的方式,或在未來一段時間內減少網絡基礎設施的資本支出,這可能會對我們的運營結果產生不利影響。我們的業務和經營結果可能會受到這些因素的重大不利影響,以及對我們的客戶產生不利影響的其他市場、行業或競爭動態。
我們面臨着激烈的競爭,這可能會損害我們的銷售和運營業績,我們預計我們運營或打算運營的競爭格局將繼續擴大,以納入其他解決方案提供商。
我們面臨着通信網絡設備、軟件和服務銷售的激烈競爭市場。全球競爭非常激烈,因爲我們和我們的競爭對手積極尋求佔領市場份額並取代現有設備供應商。歷史上,我們的行業一直由少數非常大的供應商主導,其中一些供應商擁有比我們更多的財務、營銷和研發資源、更廣泛的產品供應以及與服務提供商和其他客戶群體更建立的關係。此外,爲了推動規模和市場份額的增長並滿足跟上技術創新步伐所需的密集投資能力,網絡解決方案供應商之間的收購活動有所增加。我們行業的整合可能會導致競爭對手擁有更大的資源、定價靈活性或其他協同效應,這可能會爲他們提供競爭優勢。
我們的某些客戶正在採取採購策略,尋求從兩個或更多供應商購買更廣泛的網絡解決方案。隨着這些客戶轉向雙或多個供應商策略並添加新供應商,我們可能會失去作爲唯一或主要供應商的地位。我們還與許多較小的公司競爭,這些公司在特定產品、應用、客戶群體或地理市場方面提供了重大競爭。由於他們的努力重點較窄,這些競爭對手可能在特定的產品利基或商業機會中對客戶更具吸引力。
一般來說,我們市場的競爭基於以下因素中的任何一個或組合:
網絡解決方案的功能、速度、容量、可擴展性和性能;
滿足業務需求並推動成功成果的能力;
性能價格、每位成本和網絡解決方案的總擁有成本;
現有業務關係的有效性和強度;
技術路線圖和前瞻創新能力,包括在研發上投入大量資金的能力;
交付產品和功能的上市時間;
公司穩定和財務健康;
能夠提供全面的網絡解決方案,包括硬件、軟件和服務;
平台的靈活性和開放性,包括易於集成、互操作性和集成管理;
能夠提供適應一系列不同消費模式的解決方案;
運營成本和總擁有成本;
軟件和網絡自動化能力;
管理具有挑戰性的供應鏈環境的能力,包括製造和交貨期能力;
服務和支持能力;
企業、產品開發、支持流程和產品的安全;
網絡解決方案的空間要求和功耗;以及
能夠提供解決方案,幫助客戶管理其網絡的生命週期影響並實現其氣候可持續發展目標。

我們戰略的一部分是利用我們的技術領先地位,積極佔領額外的市場份額並取代競爭對手,特別是與國際通信服務提供商。爲了維持我們的現有地位或確保新客戶機會,我們過去並可能在未來同意激進的定價、商業讓步和其他不利條款,導致特定訂單或一組訂單的毛利率較低或負。競爭還可能導致繁瑣的商業和法律條款和條件,給我們帶來不成比例的風險。
隨着我們投資互補技術或鄰近市場機會,以及網絡運營商追求多樣化的網絡策略和消費模式,我們預計行業的競爭將繼續擴大和加劇。隨着這些變化的發生,我們預計我們的業務將與額外的網絡進行更直接的競爭

解決方案供應商,包括IP路由器供應商、組件供應商和其他網絡技術供應商或集成商。此外,隨着我們尋求更多的客戶採用我們的藍色星球自動化軟件和服務,以及網絡運營商對可編程性、自動化和分析的需求增加,我們預計將與軟件供應商和IT供應商或這些解決方案的集成商進行更直接的競爭。我們還可能面臨來自系統和組件供應商的競爭,包括我們供應鏈中的供應商,這些供應商開發基於現成或商品化硬件技術(稱爲「白盒」硬件)的網絡產品,並且我們正在尋求額外的方法來將我們的網絡平台中的使能技術推向市場。競爭強度的增加、新消費模式的採用、我們進入新市場或新競爭對手進入我們的市場可能會對我們的業務和經營業績產生不利影響。
將研發資源投資於市場需求不足的通信網絡技術,或未能充分或及時投資於市場需求高的技術,將對我們的收入和盈利能力產生不利影響。
通信網絡硬件和軟件解決方案市場的特點是技術快速發展、市場需求變化以及越來越多地採用基於軟件的網絡解決方案。我們不斷投資於研究和開發,以維持或增強我們現有的硬件和軟件解決方案,並開發或獲取包括新軟件平台在內的新技術。從啓動這些開發舉措到將新的或改進的解決方案推向市場,往往需要一段很長的時間。因此,不能保證我們的新產品或對其他解決方案的增強將獲得市場接受,也不能保證市場採用的時間將如預期的那樣。一般來說,我們的一些發展決策,包括收購、研發或技術投資的重大支出,很可能達不到我們的預期,我們在一些項目上的投資將無利可圖。還有一種可能是,我們可能會錯過預期的市場機會,因爲我們沒有在客戶或我們銷售的市場尋求的技術、產品或增強功能上投資或投資得太晚。市場需求或投資優先順序的變化也可能導致我們中斷現有或計劃中的新產品或功能開發,這可能會對我們與客戶的關係產生破壞性影響。此外,如果不能在成本效益的基礎上開發對客戶有吸引力並對我們有利可圖的創新的新解決方案或增強型解決方案,可能會對我們的業務、運營結果、財務狀況和現金流產生重大不利影響。
我們沒有購買保證,並且必須定期爲現有客戶重新贏得業務。

一般來說,我們的客戶合同不要求客戶購買任何最低或保證數量,我們通過框架合同進行銷售,客戶根據框架合同下訂單,他們通常有權修改或取消訂單。我們必須定期與所有客戶群體的現有客戶競爭並贏得業務。此外,雲提供商的採購週期往往比我們的一些傳統客戶更短,這可能要求我們與這些客戶進行比與其他客戶群更頻繁的競爭以重新贏得業務。因此,我們無法保證我們的在職能力將在任何特定客戶上保持,也無法保證我們在特定時期從客戶獲得的收入水平可以在未來時期實現。客戶支出水平可能是不可預測的,我們對任何客戶的銷售可能隨時大幅減少或停止。

網絡設備銷售通常涉及漫長的銷售週期和漫長的合同談判,這可能需要我們同意對定價、風險分配、付款和收入確認時間產生負面影響的商業條款或條件。

我們的銷售工作,特別是與通信服務提供商、雲提供商和其他大客戶的銷售工作,往往涉及較長的銷售週期。這些銷售工作通常需要投入大量的時間和資源,其中可能包括廣泛的產品測試、實驗室或網絡認證、網絡或區域特定產品認證以及網絡部署的同質化要求。即使在客戶將其業務授予我們或決定購買我們的解決方案之後,部署前的時間長度也可能會根據客戶的日程安排、站點就緒性、網絡部署的規模、所需定製配置的程度和其他因素而有所不同。此外,這些銷售還經常涉及曠日持久、有時甚至是困難的合同談判,在談判中,我們可能認爲有必要同意不利的合同或商業條款,這些條款會對定價產生不利影響,使我們面臨延誤或不履行的懲罰,並要求我們承擔不成比例的風險。爲了保持與關鍵客戶的現有關係,我們過去和未來可能會被要求提供折扣價格、做出商業讓步或提供與我們與這些客戶的歷史業務安排相比不那麼優惠的條款。我們還可能被要求提供延期付款條件、供應商或第三方融資或其他延長付款時間的替代購買結構。或者,客戶可能會堅持我們認爲過於苛刻或不符合我們最佳利益的條款和條件,而我們可能無法達成商業協議。因此,我們可能會產生大量費用,並將時間和資源投入到從未實現或導致低於預期的銷售額和毛利率的潛在銷售機會上。

如果我們無法使我們的業務適應客戶採用的網絡解決方案的消費模式,並在這些消費模式中提供有吸引力的解決方案,我們的業務、競爭地位和運營業績可能會受到不利影響。
不斷增長的帶寬需求和網絡運營商降低成本的努力導致了設計和採購網絡基礎設施的各種方法。我們將這些不同的方法稱爲「消費模式」。這些消費模式可以包括:傳統系統採購完全集成的解決方案,包括從同一供應商採購硬件、軟件和服務;從一個供應商採購完全集成的硬件解決方案,單獨使用網絡運營商自己的基於SDN的控制器;從一個供應商採購具有開放接口的集成光子線路系統,從不同的供應商單獨或「分解」採購調制解調器技術;或爲採購將與開放源碼軟件一起使用的「白盒」硬件而開發和使用已公佈的參考設計和開放源碼規範。與此同時,網絡運營商也在探索軟件解決方案的採購替代方案,範圍從集成和專有軟件平台到完全開放源代碼的軟件。
我們認爲,網絡運營商將繼續考慮多種不同的消費模式。這些方法中的許多都處於非常早期的開發和評估階段,模式的類型及其採用程度在很大程度上將取決於特定網絡運營商的環境和戰略的性質。在我們的客戶中,AT&T、某些雲提供商和其他公司正在實施網絡戰略,強調增強軟件可編程性、網絡管理和控制以及部署「白盒」硬件。許多網絡運營商正在尋求部署更小的外形尺寸、可插拔的調制解調器技術,特別是在交換和路由解決方案中,作爲集成光纖網絡平台的替代方案。其他網絡運營商,包括我們的某些雲提供商客戶,在過渡到軟件定義的網絡、通信網絡解決方案的標準化以及基於支持第三方組件的自有硬件平台組裝方面發揮着主導作用。我們認爲,網絡基礎設施採購的不同方法的潛力將要求網絡運營商和供應商隨着時間的推移發展和擴大他們現有的解決方案和商業模式。採用一系列消費模式也可能改變和擴大我們的競爭格局,將其他技術供應商包括在內,包括路由供應商、組件供應商和it軟件供應商。如果我們不能使我們的業務適應這些新的消費模式,並提供有吸引力的解決方案和商業模式,以適應我們的客戶最終或在我們的市場內採用的一系列消費模式,我們的業務、競爭地位和運營結果可能會受到不利影響。
我們的上市活動以及WaveLogic一致調制解調器技術在高性能收發器/調制解調器市場中的分佈可能會使我們面臨更多或新形式的競爭,或對我們現有的系統業務和運營結果產生不利影響。

我們最近進入了高性能收發器/調制解調器市場,以使我們的相干光纖技術貨幣化,擴大我們的潛在市場,並滿足網絡解決方案的一系列客戶消費模式。以這種方式提供我們的關鍵技術可能會對我們現有系統業務中的產品銷售產生不利影響。例如,我們的客戶可以選擇採用細分消費模式或嵌入Ciena設計的光模塊的第三方解決方案,而不是從我們這裏購買基於系統的解決方案。因此,我們可能會遇到這樣的情況,即我們直接在市場上與我們的競爭對手之一的系統競爭,該系統採用了Ciena設計的模塊或其他組件技術。提供這一關鍵技術並允許第三方銷售Ciena設計的模塊可能會對我們的競爭地位產生不利影響,並增加第三方在未經我們授權的情況下挪用或試圖使用我們的技術或相關知識產權的風險。與銷售我們的WaveLogic相干技術相關的這些風險或其他風險或意想不到的負債或成本可能會損害我們的聲譽,並對我們的業務和運營結果產生不利影響。我們進入市場的活動以及我們的WaveLogic相干技術在高性能收發器/調制解調器市場的分銷可能會使我們面臨更多或新形式的競爭,或對我們的系統業務和運營結果產生不利影響。
在當前環境下將必要的庫存水平準確匹配到客戶需求具有挑戰性,我們可能會產生額外成本或被要求註銷大量庫存,這將對我們的運營業績產生不利影響。
從2021財年第二季度到2022財年第三季度,在供應環境受到限制的時期,我們的產品和服務收到了前所未有的訂單。我們採取了一系列措施來緩解這些挑戰,包括延長採購承諾以及與供應商或通過供應商發出不可取消的提前訂單,特別是對於長交貨期零部件。截至2023年10月28日,我們對合同製造商和零部件供應商的庫存未完成採購訂單承諾爲17億美元。我們還擴大了製造能力並積累了可用原材料庫存,以便隨着供應較短零部件的供應限制得到緩解,我們能夠更快地生產成品。由於這一策略,我們的庫存從374.3美元增加
27

目錄表
2021財年末的11億美元至2023財年末的110億美元。這些庫存做法及其相關成本在最近的財政期間對我們的運營現金產生了不利影響,並且可能在未來繼續產生不利影響。

這些庫存做法,特別是在我們積壓的背景下考慮時,進一步帶來了過時的風險,可能會影響我們的運營結果和財務狀況。在2023財年,某些客戶,包括北美的通信服務提供商和有線電視和多服務運營商以及雲提供商,早先下了大量預訂單,重新安排了部分此類訂單的交付時間。因此,我們在特定時期的庫存需求可能會波動,很難預測。如果我們的客戶長時間取消或推遲訂單,庫存可能會過時,我們可能被要求註銷或減記與這些訂單相關的庫存。此外,如果客戶取消或推遲我們對合同製造商或供應商有重大未履行承諾的現有或預測訂單,我們可能需要根據這些承諾購買我們無法銷售的庫存。如果我們被要求註銷或減記大量庫存,我們在適用期間的經營業績將受到重大不利影響。我們無法有效地管理庫存與客戶需求的匹配,特別是在任何供應受限的環境下,這可能會對我們的運營結果和財務狀況產生不利影響,並可能導致收入損失、成本增加或延誤,從而對客戶滿意度產生不利影響。

如果網絡軟件市場沒有按照我們預期的方式發展,或者如果客戶不採用我們的Blue Planet自動化軟件和服務,我們可能無法將這些軟件資產貨幣化並實現我們業務戰略的關鍵部分。
我們業務戰略的一個關鍵部分是增加客戶對我們的藍色星球自動化軟件的採用。如果與網絡自動化軟件解決方案相關的市場(包括服務協調、路由優化、分析和保證以及多雲協調)不能像我們預期的那樣發展,或者如果我們無法在這些市場中商業化、提高市場知名度並採用我們的Blue Planet Automation軟件和服務,則我們的Blue Planet Automation軟件和服務的收入可能無法增長。我們在商業化和銷售這些軟件解決方案方面的歷史有限,我們正在繼續增強我們的藍色星球產品組合的能力。此外,這些解決方案的市場和競爭格局是動態的,很難預測重要的趨勢,包括這個市場的潛在增長(如果有的話)。如果這些軟件解決方案的市場沒有以我們預期的方式發展,或者如果客戶沒有采用我們的Blue Planet Automation軟件和服務,我們的增長戰略的一部分將受到不利影響,我們的財務業績可能會受到影響。
我們面臨的客戶和經銷商的信用風險可能會導致收取應收賬款變得困難,並可能對我們的收入和經營業績產生不利影響。
在我們向客戶和轉售渠道合作伙伴銷售的過程中,我們可能難以收取應收賬款,並且我們的業務和經營業績可能面臨與無法收回帳戶相關的風險。資本市場缺乏流動性、宏觀經濟疲軟和市場波動可能會增加我們面臨的這些信用風險。我們試圖監控客戶支付能力並採取適當措施來保護自己可能還不夠,我們可能不得不減記或註銷應收賬款。此類減記或註銷可能會對我們發生期間的經營業績產生負面影響,如果規模較大,可能會對我們的收入和經營業績產生重大不利影響。
我們可能被要求減記某些重大資產的價值,這將對我們的經營業績產生不利影響。
截至2023年10月28日,我們的資產負債表上有許多重要資產,其價值可能會受到與我們業務和經營業績相關的因素以及我們控制之外的因素的不利影響。截至2023年10月28日,我們的資產負債表包括 80930萬 淨遞延稅資產。我們的淨遞延所得稅資產的價值可能會受到稅收政策變化、未來稅率變化或我們的稅務規劃策略的顯着影響。如果需要進行任何減記,我們的經營業績可能會受到重大不利影響。

截至2023年10月28日,我們的資產負債表還包括 44480萬美元 善意的。如果發生事件或情況變化,很可能導致報告單位的公允價值降至低於其公允價值,我們每年以及在年度測試之間測試每個報告單位的聲譽損失。截至2023年10月28日,我們的資產負債表還包括 57500萬美元 長期資產,其中包括20560萬美元的無形資產。對我們的長期資產的估值要求我們對產品的未來銷售價格和銷量做出假設。這些假設用於預測我們的估計所基於的未來未貼現現金流。如果市場狀況或我們對業務或任何特定經營分部的預測發生變化,我們可能需要重新評估這些資產的價值。我們可能被要求對我們的聲譽和長期資產記錄減損費用,或對我們的遞延資產記錄估值撥備
28

目錄表
稅收資產。這些重要資產價值的任何減記都將導致我們在此期間的盈利減少或虧損增加。如果我們被要求進行大幅減記或減記,我們的經營業績將在該期間受到重大不利影響。
影響我們產品的性能、互操作性、可靠性或安全性的問題可能會損害我們的商業聲譽並對我們的運營結果產生負面影響。
開發和生產用於通信網絡設備的複雜硬件和軟件是非常複雜的。我們的一些產品只有在部署在通信網絡中或使用其他設備傳輸流量時才能進行全面測試,並且軟件產品可能包含可能干擾預期性能的錯誤。因此,對於新產品的初始部署和產品改進,未發現的缺陷或錯誤以及產品質量、互操作性、可靠性、安全性和性能問題往往更加嚴重。我們最近推出了或正在推出許多新的硬件和軟件產品,包括我們的WaveLogic相干光纖調制解調器技術的新發展,以及針對邊緣、接入和聚合網絡的新的路由和交換平台和解決方案。意外的產品性能問題可能與我們產品的設計、製造、安裝、操作和互操作性有關。第三方提供的組件、軟件或製造、安裝或維護服務以及從第三方獲得或獲得許可的技術中的缺陷也可能導致未檢測到的錯誤。有時,我們不得不更換某些組件,提供軟件補救措施或其他補救措施,以應對缺陷或錯誤,未來我們可能不得不再次這樣做。此類事件的補救可能會對我們的業務和運營結果產生重大不利影響。此外,我們已經並可能繼續遇到與我們的技術相關的意外安全漏洞,包括由於我們供應鏈的活動和我們使用第三方軟件的結果。我們的產品用於客戶網絡並傳輸一系列敏感信息,我們的軟件產品,包括我們的Blue Planet解決方案,在管理網絡元素和提供服務方面發揮着重要作用。通信技術經常成爲包括民族國家和其他惡意方在內的一系列威脅行爲者攻擊的目標。我們的解決方案實際或感知到的任何漏洞、惡意軟件或網絡攻擊風險都可能導致責任或監管行動,並對我們的業務和運營結果產生不利影響。產品性能、可靠性、安全性和質量問題可能會導致以下部分或全部影響:
損害我們的聲譽、銷售下降和訂單取消;
修復缺陷或更換產品的成本增加;
支付違約金、合同或類似罰款,或因業績失敗或延誤而提出的其他索賠;
由於故障率較高、額外的現場服務義務或與缺陷相關的其他重製成本而導致保修費用或估計增加;
因庫存報廢增加而收取更高費用;
擾亂我們網絡運營商客戶的運營;
向客戶或監管機構報告和其他發佈;
保險範圍不涵蓋或可從第三方收回的成本、責任和索賠;以及
確認收入或收取應收賬款的延遲。
與影響我們產品質量、可靠性和安全性的未檢測到的錯誤相關的這些和其他後果可能會對我們的業務和運營結果產生負面影響。
戰略收購和投資可能會擾亂我們的運營,並可能使我們面臨成本增加和意外負債。
我們不時收購或投資其他科技公司,或建立其他戰略關係,以擴大我們所瞄準的市場、多元化我們的客戶群或收購或加速技術或產品的開發。爲此,我們可能會使用現金、發行可能稀釋我們當前股東的股票、產生債務或承擔債務。戰略交易可能涉及許多額外風險,包括:
未能完成或延遲完成此類交易;
未能實現預期的交易利益或預期的財務業績和運營協同效應;
高於預期的收購和整合成本;
由於運營、產品、技術和人員的整合和合理化而造成的干擾;
轉移管理注意力;
被收購公司完成項目困難以及與在建項目相關的成本;
難以管理客戶轉型或進入新市場;
關鍵員工的流失;
中斷或終止與客戶、供應商、供應商、房東、許可人和其他業務合作伙伴的業務關係;

目錄表
財務報告內部控制無效;
對不熟悉的供應商或製造商的依賴;
承擔或面臨意外責任,包括知識產權侵權或其他法律索賠;以及
不利的稅務或會計影響。
由於這些風險和其他風險,我們的收購、投資或戰略交易可能無法實現預期利益,並最終可能對我們的業務、運營業績和財務狀況產生負面影響。
與人工智能(AI)的開發和使用相關的新問題可能會引發法律或監管行動,損害我們的聲譽或對我們的業務造成重大損害.
我們在產品和運營中開發和使用人工智能技術仍處於早期階段。雖然我們的目標是負責任地開發和使用人工智能,並試圖緩解使用人工智能帶來的倫理和法律問題,但我們最終可能無法在問題出現之前發現或解決問題。人工智能技術是複雜和快速發展的,我們開發或使用的技術最終可能是有缺陷的。此外,人工智能技術受到快速發展的國內和國際法律法規的約束,這可能會給公司帶來巨大的成本和義務。例如,2023年,拜登政府發佈了一項關於安全、可靠和值得信賴的人工智能的新行政命令,歐盟引入了人工智能法案,爲提供商和用戶建立規則。新出現的法規可能涉及數據隱私、數據保護和人工智能的道德使用,以及澄清知識產權方面的考慮。我們使用人工智能可能會導致法律或監管行動、更嚴格的審查或責任、損害我們的聲譽或以其他方式對我們的業務造成實質性損害。
與宏觀經濟環境和我們的全球存在相關的風險
宏觀經濟和市場狀況的不利變化以及客戶因這些情況而減少的支出水平可能會對我們的業務和經營業績產生不利影響。
我們的業務和經營業績在很大程度上取決於一般的市場和經濟狀況。我們所在地區的市場波動和疲軟以前曾導致對我們的產品和服務的需求持續下降,對我們的經營業績產生了不利影響。當前的全球宏觀經濟環境不穩定,並繼續受到通貨膨脹、影響全球供應鏈的地緣政治趨勢、利率上升和客戶消費的動態環境的重大不利影響。宏觀經濟和市場狀況也可能受到美國和國際市場各種政治、經濟或其他因素的不利影響,這些因素反過來可能對我們的客戶及其最終用戶的支出水平產生不利影響,並可能在我們經營的市場造成波動或惡化條件。由於我們的收入集中在美國,我們預計資本支出環境的任何不利變化或美國宏觀經濟或市場疲軟都將產生更重大的影響。宏觀經濟的不確定性或疲軟可能導致:
減少客戶支出以及延遲、推遲或取消網絡基礎設施計劃;
對更少的網絡項目和銷售機會的競爭加劇;
定價壓力增加,可能對收入、毛利率和盈利能力產生不利影響;
預測經營業績以及做出預算、規劃和未來投資決策的能力下降;
增加了管理費用和生產成本佔收入的百分比;
爲我們或我們的客戶的資本支出提供資金所需的信貸市場收緊;
客戶財務困難,包括訂單取消、交貨推遲、收款週期較長以及收款應收賬款或應收賬款覈銷困難;
我們的供應商或其他合作伙伴面臨的業務和財務困難,包括對材料成本、銷售、流動性水平、繼續投資其業務的能力、進出口貨物的能力、履行發展承諾的能力和製造能力的影響;以及
與多餘和過時庫存相關的費用以及其他無形資產覈銷的風險增加。
我們的每個客戶都有一系列獨特的情況,目前尚不清楚宏觀經濟和市場狀況如何繼續影響他們的購買量或行爲。爲應對全球或我們經營的特定地區不利或不確定的宏觀經濟和市場狀況而減少客戶支出,將對我們的業務、運營業績和財務狀況產生不利影響。

我們的銷售和運營規模的國際化使我們面臨額外的風險和費用,這可能會對我們的運營業績產生不利影響。

我們在全球範圍內營銷、銷售和服務我們的產品,在多個國家/地區保留人員,並依靠全球供應鏈採購重要零部件和製造我們的產品。我們的國際銷售和運營面臨固有風險,包括:
不利的社會、政治和經濟狀況,例如持續的通貨膨脹和利率上升;
貨幣匯率不利變化的影響;
應收賬款收款難度加大,收款期限延長;
人員配備和管理海外業務的難度和成本;
腐敗或不道德商業行爲的發生率和風險較高;
一些國家知識產權保護較少;
稅收和海關變化對我們的全球採購策略、製造實踐、轉讓定價或我們產品的全球銷售競爭力產生不利影響;
遵守某些測試、認證或產品定製以符合當地標準;
自由貿易協定、貿易保護措施、關稅和其他進口措施、出口合規性、經濟制裁措施、國內優惠採購要求、開展業務資格和額外監管要求的重大變化;
自然災害(包括氣候變化造成的)、戰爭或恐怖主義行爲以及公共衛生緊急情況,包括COVID-19大流行;以及
歐洲、亞洲和我們開展業務的其他地區的經濟、法律和政治狀況不確定,包括英國脫歐對英國與歐洲關係的持續影響、俄羅斯與烏克蘭、以色列和哈馬斯之間持續的軍事衝突以及中國-臺灣和美國的變化。中國關係。

我們利用一種採購戰略,強調全球採購直接或間接依賴於在亞太地區有業務的多家供應商的材料。我們還依賴第三方合同製造商,包括那些在加拿大、墨西哥、泰國和美國設有工廠的製造商來製造、支持和運輸我們的產品。與氣候變化相關的物理、法規、技術、市場、聲譽和法律風險在這些地區和全球範圍內的影響和多樣性都在增加,對我們的業務或運營結果產生的任何短期或長期不利影響的程度尚不清楚。氣候變化的實際影響,包括某些類型的自然災害更頻繁、更強烈或天氣模式變化的結果,可能會擾亂我們的供應鏈,導致我們的設施損壞或關閉,否則可能對我們的業務、運營業績和財務狀況產生不利影響。另見以下標題爲「的風險因素」與環境、氣候變化和社會倡議相關的政府法規可能會對我們的業務和經營業績產生不利影響.”
我們的國際業務受到複雜的外國和美國法律法規的約束,包括反賄賂和腐敗法、反壟斷或競爭法、數據隱私法(如GDPR)和環境法規等。特別是,近年來美國監管機構的反賄賂執法活動大幅增加,我們目前在世界上許多公認或被視爲有更大腐敗潛力的地區開展業務並尋求開展業務。違反任何這些法律和法規都可能導致罰款和處罰,對我們或我們的員工進行刑事制裁,禁止我們的業務行爲以及我們在某些地區提供產品和服務的能力,並對我們的商業聲譽造成嚴重損害。我們促進遵守這些法律法規並降低這些風險的政策和程序可能不會保護我們免受員工或第三方供應商(包括承包商、代理商和服務合作伙伴)的所有行爲的影響,也不能保護我們免受此類法律的誤解或改變適用的影響。此外,遵守這些法律的成本(包括調查、審計和監督的成本)可能會對我們目前或未來的業務產生不利影響。
我們的業務、業務和財務業績也可能因重要地理區域的不穩定、中斷或破壞而受到不利影響,包括戰爭、恐怖主義、騷亂、內亂或社會動亂;自然災害或人爲災難;突發公共衛生事件;或經濟不穩定或疲軟。例如,2022年2月,俄羅斯和烏克蘭之間的武裝衝突升級。美國和其他某些國家已經對俄羅斯實施了制裁,並可能實施進一步的制裁,這可能會損害或擾亂國際商業和全球經濟。我們正在遵守美國和國際社會對俄羅斯實施的一系列制裁和出口管制要求,2022年3月,我們宣佈決定立即暫停在俄羅斯的業務運營。儘管這一決定沒有對我們2022財年或2023財年的運營結果產生實質性影響,因爲我們在俄羅斯的業務歷來有限,但無法預測這場衝突的更廣泛或更長期的後果,其中可能包括進一步的制裁、出口管制和進口限制、禁運、地區不穩定、地緣政治變化以及對宏觀經濟條件、安全條件、貨幣匯率和金融市場的不利影響。這種地緣政治的不穩定和不確定性可能會對我們根據貿易限制、制裁、禁運和出口管制法律限制向某些國家和地區的客戶銷售產品、向客戶發貨、從客戶那裏收取款項和提供支持的能力產生負面影響,以及
31

目錄表
物流限制,包括關閉領空,可能會增加成本、風險和供應鏈和物流挑戰的不利影響。
我們國際銷售和運營的成功在很大程度上取決於我們有效預測和管理這些風險的能力。我們未能管理其中任何風險可能會損害我們的國際業務,減少我們的國際銷售,並可能導致負債、成本或其他業務困難,從而可能對我們的運營和財務業績產生不利影響。
增加我們的銷售額和在目標國際市場佔領市場份額的努力可能不會成功。
我們業務和增長戰略的一部分是通過直接和間接銷售資源的結合擴大我們的地理覆蓋範圍並增加國際市場的市場份額。我們還在積極尋找其他地區(包括EMEA和APAC)的服務提供商客戶的機會。我們市場和客戶群的多元化是我們近年來業務增長的重要組成部分。我們繼續增加銷售額和佔領國際市場份額的努力最終可能不會成功,或者可能會對我們的財務業績(包括毛利率)產生不利影響。我們未能繼續提高國際市場的銷售額和市場份額可能會限制我們的增長並損害我們的運營業績。
我們可能會受到貨幣匯率波動的不利影響。

作爲一家擁有全球業務的公司,我們面臨着外匯匯率變動的風險敞口。由於我們的全球業務,我們的收入、運營費用以及資產和負債的一部分是以非美元計價的,因此受到外幣波動的影響。由於我們在加拿大、歐洲、亞洲和拉丁美洲的非美元計價運營費用增長,我們面臨着貨幣匯率的風險敞口。美元升值可能會增加我們產品在美國以外以美元銷售的市場上客戶的實際成本,而美元疲軟可能會增加當地運營費用以及我們以外幣購買的材料或服務的成本。我們不時對沖與預期外幣現金流或以外幣計價的資產及負債相關的貨幣風險。這種試圖抵消匯率波動影響的努力代價高昂,我們無法對沖所有匯率波動。與這些對沖工具相關的損失以及外幣匯率波動的不利影響可能會對我們的經營業績產生負面影響。
與我們的運營和對第三方的依賴相關的風險
我們可能會在產品的開發和生產中遇到延誤,這可能會對我們的競爭地位和業務產生負面影響。
我們的硬件和軟件網絡解決方案,包括我們的WaveLogic調制解調器技術及其組件,都基於複雜的技術,我們在開發、製造和將這些解決方案推向市場時可能會遇到意想不到的延遲。我們或我們的供應鏈在產品開發工作方面的拖延可能會影響我們在客戶中的聲譽,影響我們捕捉市場機會的能力,並影響對我們產品的需求的時機和水平。我們定期推出新產品和增強功能,其開發週期中的每一步都存在嚴重的失敗、返工或延誤風險,其中任何一步都可能對我們產品的成本效益和及時開發產生不利影響。特別是如果需要,返工可能是一項非常昂貴和耗時的工作。我們可能會遇到與工程開發活動和軟件有關的延誤,關鍵組件的設計、採購和製造,以及原型的開發。新技術的開發可能會增加供應鏈管理的複雜性,或者需要獲得、許可或與第三方的技術相互合作。此外,知識產權糾紛、關鍵設計元素失效和其他執行風險可能會推遲甚至阻止這些產品的發佈。如果我們不及時成功地開發或生產產品,我們的競爭地位可能會受到影響,我們的業務、財務狀況和經營結果可能會受到損害。
我們依賴第三方合同製造商,我們的業務和運營業績可能會受到與其業務、財務狀況和運營地區相關的風險的不利影響。
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;

可能挪用我們的知識產權。

如果我們的合同製造商無法或不願意製造我們的產品或產品的零部件,或者如果我們在製造過程中遇到中斷,我們可能會被要求識別和認證替代製造商,這可能會導致我們延遲或無法滿足我們對客戶的供應要求。對新合同製造商進行資格認證和開始批量生產的過程成本高昂且耗時,如果我們被要求改變或對新合同製造商進行資格認證,我們可能會經歷重大業務中斷,並可能會損失收入並損害我們現有的客戶關係。與我們合同製造商的業務、財務狀況及其運營所在地區相關的這些風險和其他風險可能會損害我們履行訂單的能力、損害我們的銷售並影響我們在客戶中的聲譽,從而對我們的業務和運營業績產生不利影響。

我們對第三方零部件供應商(包括獨家和有限來源供應商)的依賴使我們的業務面臨額外的風險,包括與我們的供應商業務和財務狀況相關的風險以及地緣政治事件引起的風險,並可能限制我們的銷售、增加我們的成本並損害我們的客戶關係。
我們維持着全球採購戰略,並依賴於構成我們供應鏈的國際市場上不同的第三方供應商。我們依賴這些第三方進行與產品設計、開發和支持相關的活動,以及產品、部件、子部件和相關原材料的採購。我們的產品包括光學和電子元件,這些元件通常只能從唯一或有限的來源獲得可靠、大量的供應。我們沒有從我們的第三方供應商那裏得到任何供應保證,在某些情況下,我們的合同安排有限,或者依賴標準的採購訂單。最近一段時間,我們一小部分集成電路組件供應商的延遲和低於預期的交貨對我們的運營結果產生了不成比例的不利影響。不能保證我們能夠在我們喜歡的時間期限內,以合理的條件,以足夠的數量和質量確保我們所需要的部件或子系統。

失去供應來源或缺乏足夠的關鍵零部件可用性,可能需要我們尋找替代來源或重新設計我們的產品,這兩種情況都可能導致業務中斷和成本增加。市場需求的增加或原材料或零部件的稀缺已經導致並可能在未來導致我們解決方案的重要零部件供應短缺、供應分配挑戰、部署延遲以及成本、交貨時間和交付週期時間表增加。許多重大的技術趨勢或發展正在進行或正在出現,包括Iot、自動駕駛汽車以及5G技術等移動通信的進步,這些趨勢或發展之前已經導致,並且我們相信將繼續導致市場對我們所依賴的關鍵原材料或零部件的需求增加。

我們的一些關鍵技術供應商依賴於在中國向客戶銷售,包括我們的競爭對手,這是他們收入的重要組成部分。最近,發生了多起重大地緣政治事件,包括貿易緊張局勢和監管行動,涉及美國和中國政府。2019年5月,美國商務部對EAR進行了修正,將華爲及其某些附屬公司添加到違反美國國家安全和外交政策利益的「實體名單」中,對向華爲出口、再出口和轉讓美國受監管的技術和產品施加了新的重大限制。2020年8月,美國商務部在實體名單中增加了更多華爲附屬公司,確認適用於華爲的臨時通用許可證到期,並修改了外國直接產品規則,標誌着其對華爲的適用範圍大幅擴大。最近,美國商務部通過修改外國直接產品規則擴大了耳朵的範圍,導致更多在美國以外製造的產品出於出口或向某些國家轉讓的目的而受到耳朵的影響

目錄表
國家和/或締約方,這增加了處理此類產品的公司的合規風險和許可義務. 我們的幾家第三方零部件供應商,包括某些獨家和有限來源的供應商,向華爲銷售產品,在某些情況下,華爲是此類供應商的重要客戶。目前,無法保證這些限制的範圍或持續時間,包括外國直接產品規則,或對華爲和其他位於中國並在那裏運營的公司採取的進一步行動,以及未來對我們供應商的任何影響。繼續限制我們的供應商向華爲和其他公司銷售產品的能力可能會對他們的業務和財務狀況產生不利影響。此外,中國正在執行一項提高中國在光電子行業能力的五年計劃。不能保證這一舉措或中國的類似舉措,如《中國製造2025》(以及美國政府針對此類舉措所採取的行動)不會對我們供應商的業務或我們獲得必要零部件的機會產生不利影響。這些以及影響我們供應商的類似行業、市場和監管中斷可能會使我們的業務面臨損失、供應不足或組件停產的風險,這可能會導致收入損失、額外的產品成本、更長的交付期和部署延遲,這可能會損害我們的業務和客戶關係。如果我們遇到與關鍵供應商的任何重大中斷或困難,影響所需組件的價格、質量、可用性或及時交付,我們的業務和運營結果將受到負面影響。

我們依賴 向第三方經銷商和分銷合作伙伴銷售我們的解決方案,向第三方服務合作伙伴銷售安裝、維護和支持功能,而我們未能有效地發展和管理這些關係,可能會對我們的業務、運營結果以及與客戶的關係產生不利影響。

爲了向新市場銷售、實現客戶群多元化、擴大解決方案的應用範圍,並補充我們的全球現場資源,我們依賴於許多國內和國際第三方經銷商、分銷合作伙伴和銷售代理,我們相信這些關係是我們業務的重要組成部分。無法保證我們將成功識別和鑑定這些資源,也無法保證我們將實現這些銷售關係的預期利益。
我們還依賴許多國內和國際第三方服務合作伙伴來補充我們的全球服務和支持資源。我們依賴這些合作伙伴來完成某些安裝、維護和支持功能。此外,隨着網絡運營商越來越多地尋求依賴供應商執行與其網絡設計、建設和運營相關的額外服務,我們的支持合作伙伴執行的工作範圍可能會增加,並且可能包括我們在提供或管理此類服務方面經驗較少的領域。我們必須成功識別、評估、培訓和認證合格的服務合作伙伴,以確保我們的產品的正確安裝、部署和維護,並確保與擴展解決方案產品相關的其他服務的熟練表現,包括現場評估和施工相關服務。
Certain service partners may provide similar services for other companies, including our competitors. We may not be able to manage our relationships with our service partners effectively, and we cannot be certain that they will be able to deliver services in the manner or time required, that we will be able to maintain the continuity of their services, or that they will adhere to our approach to ethical business practices. We may also be exposed to a number of risks or challenges relating to the performance of our service partners, including:
delays in recognizing revenue;
liability for injuries to persons, damage to property or other claims relating to the actions or omissions of our service partners;
our services revenue and gross margin may be adversely affected; and
我們與客戶的關係可能會受到影響。
隨着我們服務範圍的擴大以及客戶希望識別能夠使用統一軟件管理、集成和優化多域、多供應商網絡的供應商,我們與第三方服務合作伙伴的關係將變得越來越重要。
我們還必須評估、認證或資格第三方經銷商、分銷合作伙伴、銷售代理和服務合作伙伴,以確保他們了解、願意和有能力遵守我們的行爲標準和商業道德。對這些經銷商、代理商以及分銷和服務合作伙伴的審查和認證可能成本高昂且耗時。某些經銷商、代理商以及分銷和服務合作伙伴的運營歷史、財務資源和規模可能與我們不同。
如果我們沒有有效識別、發展和管理與第三方經銷商、分銷合作伙伴、銷售代理或服務合作伙伴的關係,或者如果他們未能以所需的方式或時間提供服務,我們的財務業績和與客戶的關係可能會受到不利影響。我們還可能對這些第三方的行爲或不行爲負責或承擔責任。我們的第三方銷售合作伙伴或代理商或服務合作伙伴的作爲、不作爲或違法行爲可能會對我們的業務、經營業績和財務狀況產生重大不利影響。

我們可能會因轉售其他公司的補充產品或技術而面臨意想不到的風險和額外義務。
我們已經與戰略供應夥伴簽訂了協議,允許我們分銷他們的產品或技術。我們可以依靠這些關係來增加互補的產品或技術,使我們的產品組合多樣化,或者滿足特定的客戶或地理市場。我們可能會在未來達成額外的OEM、轉售或類似的戰略安排。我們可能會因轉售第三方產品而產生意想不到的成本或困難。我們的第三方關係可能使我們面臨與此類合作伙伴的業務、財務狀況、知識產權和供應鏈連續性相關的風險,以及他們在開發、製造或交付產品或技術方面的延誤。客戶還可能要求我們承擔保修、賠償、服務和其他商業義務,包括對客戶的潛在責任,超過我們的技術合作夥伴向我們作出的承諾(如果有的話)。我們的一些戰略供應合作伙伴是財務資源有限的相對較小的公司。如果他們無法履行對我們或我們的客戶的義務,我們可能不得不動用自己的資源來履行這些義務。暴露在這些風險中可能會損害我們在關鍵客戶中的聲譽,並可能對我們的業務和我們的運營結果產生負面影響。
我們業務的增長取決於我們內部業務流程和信息系統的正常運作和可擴展性。採用新系統、修改或中斷服務可能會擾亂我們的業務、流程和內部控制。
我們依賴許多內部業務流程和信息系統來支持關鍵業務功能,而這些流程和系統的高效運行對於管理我們的業務至關重要。我們的業務流程和信息系統必須具有足夠的可擴展性,以支持我們的業務增長,並且可能需要修改或升級,從而使我們面臨許多運營風險。我們不斷採取措施,通過對某些流程的重組、對自動化的投資以及戰略合作伙伴或資源的參與來協助某些業務職能,從而實現業務運營的轉型和優化。例如,爲了提高運營效率和實現供應鏈運營的現代化,我們正在進行多項數字技術轉型努力,包括先進的分析、自動化和其他數字解決方案。此外,我們的業務可能會開始在新的市場上運營,並通過可能需要不同內部流程來管理的新供應鏈模式來運營。這些變化需要大量的資本和人力資源投資,可能會對我們的運營造成高昂的成本和破壞性的影響,而且可能會對管理時間產生巨大的要求。這些變化還可能需要改變我們的信息系統,修改內部控制程序,以及對員工或第三方資源進行大量培訓。我們的it系統,以及第三方it提供商或業務合作伙伴的系統,也可能容易受到我們無法控制的情況造成的損壞或中斷,包括災難性事件、電力異常或停機、自然災害(包括氣候變化的結果)、數據安全相關事件以及計算機系統或網絡故障。不能保證我們的業務系統或我們的第三方業務合作伙伴的業務系統不會受到類似事件的影響,從而使我們面臨重大成本、聲譽損害以及我們業務的中斷或損害。
重組活動可能會擾亂我們的業務並影響我們的運營業績。
我們已採取措施,包括減少人員、關閉辦公室和進行內部重組,以降低運營成本、提高效率,或重新調整我們的組織和人員配置,以更好地匹配我們的市場機會和我們的技術開發計劃。我們未來可能會採取類似的措施,以實現運營協同效應,實現我們的目標運營模式和盈利目標,或者更密切地反映我們業務戰略方向的變化,或者我們現場戰略和工作場所的演變。這些變化可能會擾亂我們的業務,包括我們的研發工作,並可能導致巨額費用,包括庫存和技術相關注銷的會計費用、裁員成本以及與整合過剩設施相關的費用。重組活動產生的大量費用或費用可能會對我們在採取此類行動期間的運營結果和現金使用產生不利影響。
如果我們無法吸引和留住合格的人才,我們可能無法有效管理我們的業務。
我們未來的成功和保持技術領先地位的能力取決於我們招聘和保留高管、工程、銷售和營銷以及支持人員的能力。吸引和留住在我們行業具有經驗的高技能技術、工程和其他人員的競爭非常激烈,我們的員工一直是我們競爭對手有針對性地招聘的對象。在我們擁有研發中心的某些司法管轄區,競爭尤其激烈,包括加利福尼亞州北部的硅谷地區,以及對工程人才的總體競爭。新冠肺炎疫情的持久影響導致員工成本上升,人員流失增加,勞動力市場和員工預期發生重大轉變。我們可能會在留住和激勵現有員工以及吸引合格人才填補關鍵職位方面遇到困難。此外,勞動力短缺和員工流動可能會增加僱傭和留住員工的難度。我們不能保證,作爲我們年度「人員戰略」一部分的計劃、舉措、獎勵和認可將成功地吸引和留住執行我們商業計劃所需的人才。
35

目錄表
由於我們依賴股權獎勵作爲薪酬的重要組成部分,特別是對於我們的高管團隊來說,因此我們的股價缺乏積極表現、贈款水平降低或薪酬計劃的變化可能會對我們吸引和留住關鍵員工的能力產生不利影響。此外,我們的任何高管都不受任何特定期限的僱傭協議的約束。我們正在實施許多勞動力規劃計劃,如果我們未能有效管理這些計劃,可能會導致關鍵人員的流失。同樣,未能正確管理這些員工轉型所需的必要知識轉移可能會影響我們保持行業和創新領導地位的能力。如果我們無法吸引和留住合格的人才,我們可能無法有效管理我們的業務,我們的運營和財務業績可能會受到影響。
此外,我們的許多團隊成員都是外國人,他們依靠簽證或工作入境許可才能在美國和其他國家合法工作。政府政策的變化和流行病等全球事件可能會干擾我們僱用或留住需要這些簽證或入境許可的人員的能力。移民政策的變化,包括美國公民及移民服務局對H-10億、L-1和其他美國工作簽證類別的監管要求實施限制性解釋,也可能對我們僱用或留住關鍵人才的能力產生不利影響,這可能會對我們的業務運營產生影響。
與知識產權、訴訟、監管和政府政策相關的風險
我們的知識產權執行起來可能困難且成本高昂。

我們通常依靠專利、版權、商標和商業祕密法的結合來建立和維護我們產品和技術的專有權。儘管我們已獲得多項專利,並且其他專利申請目前正在審批中,但無法保證任何這些專利或其他專有權利不會受到挑戰、無效或規避,或者我們的權利將爲我們提供任何競爭優勢。此外,無法保證將爲我們的未決申請頒發專利,也無法保證任何專利所允許的主張將足夠廣泛以保護我們的技術。此外,一些外國的法律可能無法像美國法律那樣保護我們的專有權。
我們面臨第三方可能試圖未經授權訪問、挪用或使用我們的知識產權的風險。我們還容易受到非法分銷或銷售假冒、被盜或不合適版本的我們產品的第三方的影響,這可能會對我們的聲譽和業務產生負面影響。防止未經授權使用我們的產品、技術和其他專有權利是困難、耗時和昂貴的,我們不能確定我們正在採取的步驟是否會檢測、防止或最大限度地減少此類未經授權使用的風險。此外,我們的知識產權戰略必須不斷髮展,以保護我們在新解決方案中的專有權利,包括我們的軟件解決方案。爲了強制執行或捍衛我們的知識產權或確定他人專有權利的有效性或範圍,可能有必要提起訴訟。這樣的訴訟可能會導致巨額成本和管理時間和資源的分流,而且不能保證我們會獲得成功的結果。任何不能保護和執行我們的知識產權的行爲都可能損害我們有效競爭的能力。
我們可能會因其他人聲稱我們侵犯其知識產權而承擔巨額費用。
第三方可能會不時提出與與我們業務相關的技術和相關標準的專利、版權、商標和其他知識產權相關的索賠或提起訴訟或其他程序。我們受到多項與專利侵權相關的索賠,並被要求根據與第三方提出的侵權索賠相關的合同賠償義務向客戶進行賠償。專利主張實體的侵權主張率正在增加,特別是在美國。一般來說,這些專利所有者既不直接製造也不直接使用專利發明,而是尋求僅通過專利許可計劃的使用費從其所有權中獲得價值。
我們可能會受到針對我們的訴訟、其他訴訟或索賠以及針對我們的製造商、供應商或客戶的索賠的不利影響,指控我們的產品和技術或其組件侵犯了第三方專有權。無論這些索賠的優點如何,它們都可能很耗時,分散我們技術和管理人員的時間和注意力,並導致昂貴的訴訟或以其他方式要求我們承擔巨額費用,包括法律費用。這些主張如果成功,可能需要我們:
支付大量損害賠償金或版稅;
遵守可能阻止我們提供某些產品的禁令或其他法院命令;
尋求使用某些知識產權的許可,這些知識產權可能無法以商業上合理的條款獲得或根本無法獲得;
36

目錄表
開發非侵權技術,這可能需要大量的努力和費用,並且最終可能不會成功;和
根據合同義務賠償我們的客戶或其他第三方,以使他們免受傷害或代表他們支付費用或損害賠償。
任何這些事件都可能對我們的業務、經營業績和財務狀況產生不利影響。我們面臨的與使用知識產權相關的風險可能會因收購而增加,因爲我們對所收購技術的開發過程以及爲防範侵犯第三方權利的風險而採取的措施的可見性將較低。
我們的產品包含經第三方許可的軟件和其他技術,如果我們不再以商業上合理的條款提供該技術,我們的業務將受到不利影響。
我們將第三方軟件和其他技術集成到我們的操作系統、網絡管理和智能自動化軟件等產品中。因此,我們可能需要從包括競爭對手在內的第三方獲得某些軟件或技術的許可。軟件或其他技術的許可可能不會或可能不會繼續以商業合理的條款向我們提供。未能獲得或維護此類許可證或其他第三方知識產權可能會影響我們的開發努力和市場機會,或者可能需要我們重新設計我們的產品或獲得替代技術。第三方許可方可能會就我們對此類技術的使用堅持不合理的財務或其他條款。我們不遵守任何許可證的條款可能會導致我們無法繼續使用該許可證,這可能會導致巨大的成本,損害我們的市場機會,並要求我們獲得或開發替代技術。
我們的一些解決方案,包括我們的操作系統軟件、平台軟件和藍色星球自動化軟件,利用了開源或公開可用的軟件元素。隨着網絡運營商尋求增強網絡的可編程性和自動化,我們預計我們和其他通信網絡解決方案供應商將越來越多地貢獻和使用由標準制定機構或其他行業論壇開發的技術或開放源碼軟件,以促進網絡層和功能的整合。此類許可證的條款可能被解讀爲可能對我們的產品商業化能力施加意想不到的條件或限制。這增加了我們與使用此類軟件相關的風險,並可能要求我們向第三方尋求許可、重新設計我們的產品或停止銷售此類解決方案。與第三方獲得和維護技術許可的困難可能會擾亂我們產品的開發,增加我們的成本,並對我們的業務產生不利影響。
針對我們的企業技術環境和資產的數據安全漏洞和網絡攻擊可能會損害我們的知識產權、技術或其他敏感信息,並對我們的業務、聲譽和運營能力造成重大損害。
在我們的正常業務過程中,我們的網絡環境和資產,以及我們的第三方業務合作伙伴的網絡和資產,包括我們的供應鏈和其他供應商,維護着某些對我們的業務具有保密、監管、專有或其他敏感性質的信息。這些信息可能包括與我們和我們的員工、客戶、供應商和其他業務合作伙伴有關的知識產權和產品信息、個人數據、財務信息和其他機密業務信息。全球網絡安全事件的頻率、複雜性和不可預測性有所增加,在國家之間出現地緣政治緊張或不穩定時期可能更加嚴重。此外,技術行業的公司,特別是網絡和通信產品製造商,越來越多地遭受各種各樣的數據安全事件,包括網絡攻擊和其他未經授權訪問網絡資產、基礎設施或敏感信息的企圖。我們的網絡系統、設備、存儲和其他業務應用程序,以及我們依賴並由我們的第三方提供商維護的系統、存儲和其他業務應用程序,在過去和將來都會受到安全事件的影響,包括攻擊、利用、入侵、破壞和其他不法行爲,或試圖獲得未經授權的訪問或進行其他未經授權的活動。此類數據安全事件可能是由第三方或內部行爲者的惡意或疏忽造成的。這些威脅來自民族國家、獨立黑客、黑客組織、有組織網絡犯罪實體和其他第三方的行動,以及來自我們組織內部或支持我們組織的惡意行爲。在某些情況下,很難預測、發現或確定這類事件的指標並評估其造成的損失。如果實際或感知的數據安全事件影響我們的網絡或我們的任何第三方提供商的網絡,我們可能會招致巨額成本,我們的技術和運營可能會受到影響,我們的客戶和其他利益相關者可能會受到影響,我們的聲譽可能會受到損害,我們可能會捲入訴訟,包括違反合同的指控。我們還可能受到更多的監管監督,包括政府調查、執法行動和監管罰款。我們還可能在報告財務結果時遇到延遲,並且由於我們無法及時爲產品和服務生產、分銷、開具發票和收取付款,我們可能會損失收入和利潤。此外,數據安全事件可能會導致巨額補救費用,並增加網絡安全保護和保險成本。

雖然我們努力保護我們的企業網絡系統並驗證我們的第三方提供商的安全性,以緩解這些潛在風險,包括通過信息安全政策、員工意識和培訓以及其他技術、程序和行政控制,但不能保證此類行動將足以防止未來的數據安全事件或內部威脅。我們在過去和預計未來都會受到一系列事件的影響,包括網絡釣魚、聲稱來自公司高管或供應商的尋求付款請求的電子郵件、惡意軟件和來自相似公司域的通信,以及內部惡意行爲者和我們使用第三方軟件和服務造成的安全相關風險。由於利用涉及我們使用第三方應用程序的零日漏洞,我們還受到機密數據未經授權的訪問和泄露的影響。雖然到目前爲止,我們遇到的這些類型的事件還沒有對我們的業務、技術、運營或我們的網絡安全產生實質性影響,但未來的數據安全事件可能會危及重大機密或其他受保護的信息,奪取、破壞或損壞數據,或以其他方式擾亂我們的運營或影響我們的客戶或其他利益相關者。我們和我們的網絡環境未來還可能受到勒索軟件攻擊、民族國家網絡攻擊或其他類型的網絡攻擊。如果不按法律要求及時披露此類重大事件,可能會導致額外的財務或監管後果。我們已經並將繼續承擔遵守法律、法規、行業標準和合同義務規定的隱私和數據保護標準和協議的費用。加強對數據收集、使用和保留做法的監管,包括自我監管和行業標準、改變現有法律和法規、制定新的法律和法規、增加執法活動以及改變法律解釋,可能會增加我們的合規和運營成本。雖然如果我們的第三方提供商未能履行其對我們的安全相關義務,我們可能有權獲得損害賠償,但任何賠償都可能不足以彌補我們的損害,或者我們可能無法追回此類賠償。雖然我們已經購買了網絡安全保險,但不能保證保險範圍足以應對發生的任何損失。此外,隨着網絡攻擊的頻率和規模的增加,我們可能無法獲得網絡安全保險的金額和條款,我們認爲足以滿足我們的行動。

我們是法律訴訟、調查和其他索賠或糾紛的一方,這些索賠或糾紛的辯護成本高昂,如果決定對我們不利,可能會要求我們支付罰款或損害賠償、採取補救措施或阻止我們採取某些行動,其中任何行動都可能對我們的業務產生不利影響。
在我們的業務過程中,我們是,未來也可能是法律程序、調查和其他索賠或糾紛的一方,這些訴訟、調查和其他索賠或糾紛已經或可能涉及商業交易、知識產權、證券、員工關係或遵守適用的法律和法規。法律程序和調查本質上是不確定的,我們無法預測其持續時間、範圍、結果或後果。不能保證這些或任何已經或將來可能對我們不利的問題將得到有利的解決。在任何與政府調查有關的情況下,如果政府對我們採取行動,或各方解決或解決問題,我們可能被要求支付巨額罰款或民事和刑事處罰,和/或受到公平補救,包括收回或禁令救濟。因此,其他法律或監管程序,包括私人訴訟當事人提起的訴訟,也可能隨之而來。這些問題的辯護、解決和/或解決可能既昂貴又耗時,並可能需要我們實施某些補救措施,這些措施可能會對我們的業務和運營造成代價高昂或中斷的影響。它們還可能對我們的商業聲譽造成損害。一個或多個這些問題的不利解決可能會對我們的業務、運營結果、財務狀況或現金流產生實質性的不利影響。
貿易政策的變化,包括徵收關稅和其他進口措施、加強出口管制和投資限制、退出或實質性修改國際貿易協定的努力,以及影響外國設備進口和銷售的其他監管努力,可能會對我們的業務、運營和財務狀況產生不利影響。
美國和各國政府制定了某些貿易和關稅要求,根據這些要求,我們對產品的採購和製造以及向世界各地客戶分銷和履行實施了全球方法。美國政府不時表示願意修改、重新談判或終止各種現有多邊貿易協定,並對進口到美國的某些商品徵收新的稅收和限制。由於我們依賴全球採購戰略和美國以外市場的第三方合同製造商來執行我們產品的幾乎所有制造工作,如果採取這些步驟,可能會對我們的業務和運營產生不利影響,增加我們的成本,並降低我們的產品在美國和其他市場的競爭力。
例如,我們的供應鏈包括某些位於中國的直接和間接供應商,他們向我們、我們的製造商或我們的第三方供應商供應貨物。最近,發生了一系列重大地緣政治事件,包括貿易緊張局勢和監管行動,涉及美國和中國政府。美國政府對一系列進口中國產品提高了關稅並徵收新關稅,包括我們解決方案的零部件和我們銷售的某些成品產品。美國涉及從中國進口的關稅政策定於2023年進行廣泛審查。美國政府還對從中國進口的據稱由美國製造的產品實施了廣泛的新限制
38

目錄表
歐盟已經討論過類似的限制措施,而其他國家正在辯論或已經對全部或部分使用強迫勞動生產的商品的進口實施了類似的限制。中國進行了報復,提高了對中國出口的某些美國商品的關稅,並徵收了新的關稅,並引入了封鎖措施,以限制國內公司遵守美國貿易限制的能力,並可能採取進一步措施對美國行業或公司進行報復。2020年5月,美國出臺了進一步的重大限制措施,限制更多的中國政府和商業實體獲得受控制的美國技術,包括我們位於中國的某些競爭對手。最近,在2022年10月,美國商務部針對向中國提供某些半導體和相關技術實施了額外的出口管制限制,這可能會進一步擾亂供應鏈,可能對我們的業務產生不利影響。此外,美國聯邦通信委員會(FCC)於2022年11月禁止被認爲對國家安全構成不可接受風險的通信設備獲得允許在美國進口、營銷或銷售產品的設備授權。這一禁令目前包括華爲及其附屬公司和子公司以及其他四家中國公司生產的電信設備,隨後可能會有更多實體添加到該名單中。涉及美國-中國貿易關係的局勢仍然不穩定和不確定,不能保證任何一個國家的進一步行動不會對我們的業務、運營和獲得從中國獲得的技術或其組件產生不利影響。另請參閱標題爲「我們對第三方組件供應商的依賴…」的風險因素上面。
At this time, it remains unclear what additional actions, if any, will be taken by the U.S. or other governments with respect to international trade agreements, the imposition of tariffs on goods imported into the U.S., tax policy related to international commerce, increased export control and investment restrictions, import or use of foreign communications equipment, or other trade matters. Based on our manufacturing practices and locations, there can be no assurance that any future executive or legislative action in the United States or other countries relating to tax policy and trade regulation would not adversely affect our business, operations and financial results.
政府對我們產品或我們產品中的技術的使用、進口或出口的監管、該監管的變化或我們未能獲得產品所需的批准,可能會損害我們的國際和國內銷售,並對我們的收入和銷售成本產生不利影響。不遵守此類法規可能會導致執法行動、罰款、處罰或限制出口特權。此外,對我們的設備徵收昂貴的關稅、進口限制、貿易保護措施和某些國家的國內優惠要求可能會限制我們進入這些市場並損害我們的銷售。這些法規可能會對我們產品的銷售或使用產生不利影響,大幅增加我們的銷售成本,並對我們的業務和收入產生不利影響。
影響通信和技術行業以及我們客戶業務的政府法規變化可能會損害我們的前景和經營業績。
FCC對美國電信行業的許多公司擁有管轄權,類似機構對其他國家的通信行業也擁有管轄權。我們的許多最大客戶,包括服務提供商以及有線電視和多業務網絡運營商,都受到這些機構的規則和法規的約束,而其他客戶則參與並受益於政府資助的鼓勵部署網絡基礎設施的計劃。這些監管要求和融資計劃可能會發生變化,可能會對我們的客戶產生不利影響,從而對我們的業務產生不利影響。
2017年12月,FCC廢除了2015年實施的大部分禁止攔截、降級或優先考慮某些類型的互聯網流量的網絡中立規則,並恢復了對寬帶服務的寬鬆監管待遇。2020年10月,上訴法院部分維持了2017年的裁決,儘管2020年的裁決撤銷了2017年命令中的具體優先購買權條款。2023年10月,FCC提議根據《通信法》第二章將寬帶互聯網接入服務(「BIAS」)重新分類爲第二章電信服務,並恢復BIAS提供商的網絡中立義務。這些規則如果獲得通過,其影響仍然不確定,可能會進行進一步的司法審查。包括加利福尼亞州在內的許多州也採取了行政行動或通過了立法,尋求重建網絡中立性,國會內部也在努力通過聯邦立法,將統一的網絡中立性要求編入法典。
監管要求的變化或與監管環境相關的不確定性可能會推遲或阻礙網絡運營商對網絡基礎設施的投資,這可能會對我們產品和服務的銷售產生不利影響。同樣,監管資費要求或與通信網絡定價或運輸條款相關的其他法規的變化可能會減緩網絡基礎設施的開發或擴展,並對我們的業務、經營業績和財務狀況產生不利影響。
另外,我們的某些雲提供商客戶一直是美國、歐洲和其他司法管轄區競爭主管部門的監管和其他政府行動的對象,包括正式或非正式的詢問和調查。2019年7月,美國司法部宣佈將對重大

目錄表
在線技術平台,2019年9月,各州總檢察長宣佈對某些科技公司進行反壟斷調查。此外,美國國會的某些委員會最近舉行了聽證會並展開調查,以考慮與這些平台相關的企業、它們對競爭的影響及其行爲。無法保證這些政府行爲不會以對我們不利的方式對我們雲提供商客戶的網絡支出、採購策略或業務實踐產生不利影響。
與環境、氣候變化和社會舉措相關的政府法規可能會對我們的業務和經營業績產生不利影響。
我們的業務受到與環境和氣候變化相關的各種聯邦、州、地方和國際法律的監管。如果我們違反或根據這些法律或法規承擔責任,我們可能會招致罰款、與財產損壞或人身傷害有關的費用以及與調查或補救活動有關的費用。我們的產品設計工作和我們產品的製造也受到與我們設備中存在某些材料或物質相關的不斷變化的要求的影響,包括要求此類產品的生產商對某些產品的收集、處理和回收負責的法規。例如,我們的運營和財務結果可能會受到環境法規的負面影響,例如歐盟已經採用的WEEE和RoHS法規。遵守這些和類似的環境法規可能會增加我們設計、製造、銷售和移除產品的成本。美國證券交易委員會「要求披露從剛果民主共和國和鄰國(」剛果民主共和國「)開採的」衝突礦物“的使用情況,並披露製造商阻止從剛果民主共和國採購此類礦物的程序。其中某些礦物存在於我們的產品中。實施這些要求的美國證券交易委員會規則可能會減少能夠供應「無衝突」零部件的供應商數量,而我們可能無法獲得足夠數量的無衝突產品或供應來滿足我們的運營需要。由於我們的供應鏈很複雜,如果我們不能充分核實我們產品中使用的「衝突礦物」的來源,也不能斷言我們的產品是「無衝突的」,我們可能會面臨客戶、股東和其他利益相關者的聲譽挑戰。環境或類似的社會倡議也可能使我們難以獲得合規部件的供應,或者可能需要我們註銷不合規的庫存,這可能會對我們的業務和運營業績產生不利影響。
與我們的環境、社會和治理實踐相關的投資者和其他利益相關者審查,以及我們披露的業績和對這些實踐的期望,可能會增加成本並使我們面臨衆多風險。
投資者、業務合作伙伴、員工、立法者、監管機構和其他利益相關者越來越關注ESG問題,包括我們的ESG實踐。隨着期望的增長,我們已經建立並溝通了與ESG事項相關的各種倡議、目標和願望。任何披露的目標和願望都反映了我們目前的計劃和假設,這些假設可能會隨着時間的推移而改變,可能無法實現。此外,追蹤和衡量ESG努力的標準和法律在許多情況下都是新的,沒有得到協調,而且還在繼續演變。我們努力遵守這些標準和法律,實現並準確報告我們的倡議、目標和抱負,這帶來了許多運營、聲譽、財務、法律和其他風險。我們的流程和控制可能並不總是與不斷髮展的標準保持一致,我們對標準的解釋可能與其他標準不同,並且標準可能會隨着時間的推移而不斷變化,其中任何一項都可能導致對我們的目標、我們報告的實現這些目標的進展或我們披露的其他ESG信息進行重大修訂。此外,任何未能或被認爲未能在我們宣佈的時間期限內追求或實現我們之前宣佈的目標、指標和目標,或未能滿足各種報告標準,或根本沒有,也可能產生類似的負面影響,並使我們面臨政府執法行動、私人訴訟和聲譽損害。
稅法或法規的變化、有效稅率和稅務當局的其他不利結果可能會對我們的經營業績產生不利影響。
我們未來的有效稅率可能會受到波動或受到稅法、法規、會計原則或其解釋變化的不利影響。所得稅對我們業務的影響也可能受到與我們業務相關的許多項目的影響。這些可能包括對我們盈利的估計和實際地域組合;我們遞延所得稅資產估值的變化;適用於我們某些地區的淨營業虧損或研發信貸安排的使用或到期;以及我們轉讓定價方法的變化、評估開發技術或進行公司間安排。
此外,經濟合作與發展組織(「經合組織」)還推出了一個實施15%全球最低企業稅的框架,稱爲第二支柱或最低稅收指令。最低稅收指令的許多方面將於2025財年開始生效,其餘的某些影響將於2026財年開始生效。雖然尚不確定美國是否會頒佈立法以採用最低稅收指令,但我們運營的某些國家已經通過立法,其他國家正在制定立法以實施最低稅收指令。雖然我們目前預計最低稅收指令不會對我們的有效性產生重大影響
40

目錄表
稅率方面,隨着經合組織繼續發佈額外指導並各國實施立法,我們的分析正在進行中。如果我們運營所在國家/地區發生額外變化,這些立法變化和努力可能會增加不確定性,並對我們的有效稅率或運營產生不利影響。

我們需要接受國稅局和全球其他稅務機關對我們的收入和其他納稅申報表的持續審查,並且我們隨時都會進行多項此類審查。稅務機關可能會不同意我們採取的某些立場,此類審查或審計的不利結果可能會對我們的財務狀況和經營業績產生負面影響。無法保證此類檢查的結果或影響我們有效稅率的稅法或法規的變化不會對我們的業務、財務狀況和運營業績產生不利影響。

未能對財務報告保持有效的內部控制可能會對我們的業務、經營業績和股價產生重大不利影響。
2002年《薩班斯-奧克斯利法案》第404條要求我們在年度報告中包括一份報告,其中包含管理層對截至本財政年度末我們財務報告的內部控制有效性的評估,以及關於此類內部控制是否有效的聲明。遵守這些要求已經導致並可能繼續導致巨大的費用以及時間和業務資源的承諾。某些正在進行的計劃,包括努力轉變業務流程或將某些職能轉移到第三方資源或提供商,將需要在我們優化業務和運營的同時對我們的內部控制系統、流程和相關信息系統進行修改。我們向新地區的擴張可能會給我們的內部控制系統帶來進一步的挑戰。我們不能確定我們目前的財務報告內部控制設計或任何額外的變化是否足以使管理層能夠確定我們的內部控制在任何時期或持續有效。如果我們無法斷言我們對財務報告的內部控制是有效的,市場對我們財務狀況的看法和我們股票的交易價格可能會受到不利影響,客戶對我們業務的看法可能會受到影響。
與我們的普通股、債務和投資相關的風險
我們的股價波動較大。
我們的普通股價格在過去經歷了很大的波動,未來可能會繼續波動。我們股票價格的波動可能是由於這一「風險因素」一節中討論的許多因素造成的。從2020財年到2023財年,我們的收盤價從每股77.60美元的高位到每股34.50美元的低位不等。股市經歷了重大的價格和成交量波動,影響了許多科技公司的市場價格,這種波動往往與這些公司的經營業績無關。我們的實際業績與我們對此類業績的前瞻性指導、投資分析師公佈的預期或市場普遍預期之間的差異,可能會導致我們的股價大幅波動。我們的股票價格也可能受到我們所在行業的市場狀況以及我們、我們的競爭對手、供應商或我們的客戶可能發佈的公告的影響。這些可能包括我們或我們的競爭對手宣佈財務業績或估計財務業績的變化、技術創新、客戶的獲得或流失,或其他戰略舉措。我們的普通股也包括在某些市場指數中,這些指數的構成發生任何變化,將我們公司排除在外,都可能對我們的股價產生不利影響。此外,如果科技股市場或更廣泛的股票市場繼續經歷投資者信心的喪失,我們普通股的交易價格可能會因爲與我們的業務、財務狀況或運營結果無關的原因而下降。這些因素以及其他影響宏觀經濟狀況或金融市場的因素,可能會對我們未來普通股的市場價格產生重大不利影響。

我們的高級有擔保信貸安排和高級無擔保票據項下的未償債務可能會對我們的流動性和運營業績產生不利影響,並可能限制我們的業務。
我們是與3億美元的高級有擔保循環信貸融資相關的信貸協議的一方,這是一筆未償還的高級有擔保定期貸款,約爲 12億美元 2030年到期,以及未償還的高級無擔保契約,據此,我們發行了本金總額爲40,000萬美元的2030年到期的4.00%優先票據。管理這些信貸設施的協議包含某些契約,這些契約限制了我們承擔額外債務、設立優先權和擔保、支付現金股息、贖回或回購股票、與關聯公司進行某些收購交易或交易、償還某些債務、進行投資或處置資產的能力。這些協議還包括習慣補救措施,包括貸方對擔保貸款的抵押品採取行動的權利,如果我們違約或無法履行債務義務,該措施將適用。

我們的債務可能會產生重要的負面後果,包括:

41

目錄表
增加我們對不利經濟和行業條件的脆弱性;
限制我們獲得額外融資的能力,特別是在不利的資本和信貸市場條件下;
可能對我們的經營業績產生不利影響並減少用於其他業務目的的現金資源的可用性的債務償還和償還義務;
限制我們規劃或應對業務和市場變化的靈活性;以及
這使我們可能處於相對於更好地獲得資本資源的競爭對手的競爭劣勢。

我們還可能會達成額外的債務交易或信貸安排,包括設備貸款、流動資金信貸額度、優先票據和其他長期債務,這可能會增加我們的負債並導致對我們的業務產生額外限制。此外,主要債務評級機構定期根據多種因素評估我們的債務。無法保證我們能夠維持現有的債務評級,否則可能會對我們的資金成本、流動性和資本市場準入產生不利影響。

資本市場的巨大波動和不確定性可能會限制我們以優惠條件或根本限制我們獲得資金的機會。
我們的業務運營需要大量的資金。我們過去曾進入資本市場,併成功籌集資金,包括通過發行股票、可轉換票據和其他債務,以增加我們的現金狀況,支持我們的運營,並採取戰略增長舉措。我們定期評估我們的流動性狀況、債務和預期現金需求,爲我們的長期運營計劃提供資金,我們可能認爲有必要或適宜在未來籌集額外資本或產生額外債務。如果我們通過進一步發行股權或可轉換爲股權的證券來籌集額外資金,或進行某些旨在解決我們現有債務的交易,我們現有股東對我們公司的所有權百分比可能會被稀釋,或者我們的槓桿和未償債務可能會增加。目前的資本市場狀況,包括通貨膨脹的影響,已經提高了借款利率,如果我們尋求額外的資金,可以預計與前幾個時期相比,我們的資本成本將顯著增加。此外,全球資本市場在過去經歷了顯著的波動和不確定時期,不能保證這些融資選擇將以有利的條件向我們提供,或者根本不能保證,如果我們認爲有必要或可取地尋求額外資本。

項目7.    管理層對財務狀況和經營成果的討論和分析

以下討論和分析應與本年度報告其他部分包含的合併財務報表及其註釋一起閱讀。

概述

我們是一家網絡平台、軟件和服務公司,提供的解決方案使各種網絡運營商能夠部署和管理向企業和消費者提供服務的下一代網絡。我們提供硬件、軟件和服務,支持通過核心、城域、聚合和接入通信網絡傳輸視頻、數據和語音流量。我們的解決方案在全球範圍內被多個垂直行業的通信服務提供商、有線和多服務運營商、雲提供商、海底網絡運營商、政府和企業使用。我們的產品組合旨在支持自適應網絡,這是我們對網絡終端狀態的願景,該網絡終端狀態利用由軟件控制和自動化功能驅動的可編程和可擴展的網絡基礎設施,並由分析和情報提供信息。我們的解決方案包括網絡平台,包括我們的光纖網絡和路由和交換產品組合,這些平台可以從網絡核心應用到最終用戶接入點,使網絡運營商能夠擴展容量、提高傳輸速度、高效分配流量並動態適應不斷變化的最終用戶服務需求。爲了補充我們的網絡平台,我們提供平台軟件,其中包括我們的管理、控制和規劃(「MCP」)應用程序,這些應用程序可提供高級多層域控制和操作。通過我們的Blue Planet軟件,我們還通過產品化運營支持系統(OSS)實現完整的服務生命週期管理自動化,其中包括庫存、協調和保證解決方案,幫助我們的客戶實現跨多供應商和多域環境的閉環自動化。

訂單量

從2021財年第二季度到2022財年第三季度,我們收到了前所未有的產品和服務訂單。在此期間,我們的季度訂單量大大超過了我們的收入和歷史訂單量,訂單集中在某些現有的雲提供商和北美的服務提供商客戶。我們認爲,這些訂單中的一部分反映了由於交貨期延長或實施供應安全戰略以解決下文所述的供應限制,客戶加快了未來訂單的速度。我們還認爲,這些訂單中的一部分反映了疫情前的設計勝利,由於新冠肺炎疫情的動態,訂單被推遲了。我們的訂單量在2022財年第四季度開始放緩。在2023財年,我們的訂單水平繼續低於收入水平,與2023財年第三季度相比,2023財年第四季度的訂單量略有增加。我們認爲,訂單相對於收入的減少在一定程度上是因爲客戶不再需要下大量的提前訂單,因爲供應鏈條件和交貨期已經改善。然而,從長遠來看,我們仍然相信,業務和消費者行爲的某些趨勢和轉變,包括企業和消費者雲網絡採用、5G、高清視頻、產生式人工智能,以及網絡運營商對彈性和自動化的關注,代表着我們業務需求和機遇的積極、長期驅動因素。

積壓和訂單交付時間

從歷史上看,我們季度收入的很大一部分來自於同一季度收到的客戶訂單(我們稱之爲「賬面收入比」),因此較難預測,並受到波動的影響。然而,由於2021財年和2022財年部分時間的訂單量上升,以及下文所述的供應鏈限制,我們產生了大量積壓的客戶訂單。因此,我們的收入最近受到了一些因素的影響,包括供應的可用性和客戶對現有積壓訂單的交付延遲。我們的積壓訂單從2020財年末的12美元億增加到2022財年末的42美元億。隨着供應鏈條件的改善,我們能夠增加出貨量並縮短交貨期,截至2023財年末,我們的積壓訂單減少到26億美元。我們預計2024財年我們的積壓訂單將繼續減少,因爲供應鏈條件繼續改善,客戶下的預訂單減少。隨着這種情況的發生,我們預計我們對獲得季度賬面收入訂單的依賴將會增加,這些訂單將代表我們季度收入的更典型構成,併成爲未來收入增長的關鍵因素。

我們完成積壓的時間和程度將對我們的收入增長率產生重大影響,並且可能受到我們控制之外的因素的影響,包括供應鏈條件和下文描述的組件的可用性,以及客戶的準備情況和接受現有訂單發貨的意願。2023財年,某些客戶,包括北美的通信服務提供商、有線電視和多業務運營商以及雲提供商,此前已下了大量提前訂單,重新安排了部分此類訂單的交付,
47

目錄表
在某些情況下,包括到2023財年結束之後。我們認爲,這是一系列因素的結果,包括這些客戶在供應鏈緊張時期的大量訂單水平,我們最近交貨提前期的迅速改善,以及他們的資本支出和庫存水平。因此,我們在特定時期的結果可能很難預測。由於這些和其他因素,我們完成積壓的時間可能會導致我們的運營結果出現一些波動,我們的積壓不一定被視爲任何特定時期收入的準確指標。見標題爲「我們的積壓可能不是我們未來收入水平和時機的準確指標」的風險因素。我們的收入、毛利率和經營業績可能會在每個季度之間出現不可預測的大幅波動。在本報告第一部分項目1A中,進一步討論了與我們的積壓和訂單交付時間有關的風險。

供應鏈限制

面對一系列行業的需求,全球對某些原材料和零部件的供應,特別是半導體、集成電路和我們大多數產品中使用的其他電子零部件的供應,在最近幾個時期經歷了很大的限制和中斷。因此,我們經歷了嚴重的零部件短缺、交貨期延長、成本增加,以及我們供應商基礎上先前承諾的關鍵零部件供應意外取消或延遲。在2023財年下半年,半導體、集成電路和其他電子元件的交付期、成本和供應的可預測性開始穩定下來,我們的大多數供應商都能夠兌現承諾,儘管交付期延長了。然而,我們預計組件交付期延長和組件成本上升至少將持續到2024財年上半年。供應緊張的情況影響了我們的收入,並將繼續影響我們在短期內銷售商品的成本,以及我們繼續以與前幾個時期一致的方式降低生產產品成本的能力。目前尚不清楚供應環境何時會完全穩定,以及它將對我們的業務和未來一段時間的運營結果產生什麼影響。

爲了減輕這些供應條件對我們業務和客戶的影響,我們已經並繼續下庫存提前訂單,並一直在積累零部件。我們還擴大了製造能力,爲更快地生產成品做好準備。由於這一策略,我們的庫存從2021財年末的37430萬美元增加到2023財年末的11億美元。加上供應成本的增加,這些緩解策略已經影響了我們的運營業績和運營現金,我們預計它們將繼續影響我們的運營業績和運營現金。

市場機遇

我們銷售通信網絡解決方案的市場是動態的,具有高變化率的特點,包括帶寬需求和網絡流量的快速增長、基於雲的服務和用於設計和採購網絡解決方案的新方法或「消費模式」的激增。新興的服務和應用,包括5G移動通信、基於光纖的接入網絡和物聯網,正在進一步影響或預計將影響有線網絡基礎設施,特別是在網絡邊緣,需要增加容量、計算能力和自動化,以提供最終用戶所需的體驗質量。許多網絡運營商面臨着限制資本支出預算的壓力,因爲他們無法以帶寬增長的速度增長網絡支出。爲了滿足這些不斷增長的服務需求並管理網絡成本,許多網絡運營商都在尋求採用下一代基礎設施,這些基礎設施更具可編程性,能夠更好地利用數據進行網絡洞察、分析和自動化。其他網絡運營商在設計和採購網絡基礎設施解決方案時正在追求一系列不同的消費模式。我們的自適應網絡願景和我們的業務戰略,以利用這些不斷變化的市場動態,包括在本年度報告第一部分第1項對我們的業務描述的「戰略」部分提出的倡議。

戰略和財務計劃

收購。 2022年11月17日,我們收購了Benu Networks,Inc.(「Benu」)及其雲原生軟件解決方案組合,包括虛擬寬帶網絡網關(v)BNG),其補充了我們現有的寬帶接入解決方案組合。2022年12月30日,我們收購了Tibit Communications,Inc.(「Tibit」),無源光網絡解決方案提供商。請參閱我們的註釋4 本報告第二部分第8項包含的合併財務報表,以獲取有關這些收購的更多信息。

信貸設施再融資。 2023年10月24日,我們對現有信貸協議(日期爲2014年7月15日)簽訂了一份增量修訂協議(「信貸協議」),據此,我們產生了一批新的單一優先擔保定期貸款,本金總額爲12億美元,於2030年10月24日到期(「2030年新定期貸款」)。2030年新定期貸款的收益連同手頭現金用於全額償還(i)我們現有的高級有擔保定期貸款,未償還本金總額約爲66870萬美元,以及
48

目錄表
將於2025年9月28日到期(「2025年定期貸款」),以及(ii)我們現有的高級有擔保定期貸款,未償還本金總額約爲49750萬美元,將於2030年1月19日到期(「2030年定期貸款」),包括應計利息,並支付交易費用和費用。請參閱我們的註釋19 本報告第二部分第8項包含的合併財務報表,以獲取有關我們定期貸款的更多信息。

2023年10月24日,根據上述信貸協議的增量修訂協議,我們簽訂了一項價值30000萬美元的新高級有擔保循環信貸融資(「循環信貸融資」),於2028年10月24日到期,取代了9月25日到期的最高30000萬美元的前身高級有擔保資產循環信貸融資,根據我們日期爲2019年10月28日的ABL信貸協議(經修訂)(「ABL信貸協議」),2025年(「ABL信貸融資」)。在簽訂循環信貸機制的同時,ABL信貸協議也被終止。我們打算使用循環信貸機制來支持在我們的正常業務過程中以及出於一般企業目的而產生的信用證的簽發。請參閱我們的註釋20 本報告第二部分第8項包含的合併財務報表,以獲取有關我們循環信貸安排的更多信息。

財年年終積壓

一般而言,我們根據客戶根據框架協議下的採購訂單進行銷售,框架協議管轄我們產品和服務銷售的一般商業條款和條件。這些協議不要求客戶購買任何最低或保證的訂單數量。在計算積壓時,我們只包括(I)尚未發貨的產品和尚未履行的服務的客戶訂單;以及(Ii)與已交付的產品和已履行的服務相關的客戶訂單,但根據適用的合同條款,這些訂單正在等待客戶接受。一般來說,我們的客戶可以在事先通知有限的情況下取消、推遲或更改他們的訂單,或者他們可能決定不接受我們的產品和服務,儘管取消和不接受的情況很少發生。可以在收到採購訂單後幾個季度完成積壓,或者在某些服務義務的情況下,可能與多年支持期限有關。因此,積壓不一定被視爲任何特定時期未來收入的準確指標。

截至2023年10月28日,我們的積壓金額爲26億美元,而截至2022年10月29日,積壓金額爲42億美元。積壓包括來自商業和政府客戶的產品和服務訂單,我們的顯着年度增長反映了上述需求動態。截至2023年10月28日的積壓包括約3.362億美元,主要與預計不會在2024財年內完成或執行的產品以及維護和支持服務訂單有關。由於不同的公司可以以不同的方式定義積壓,因此我們對積壓的呈現可能無法與行業中其他公司呈現的數字進行比較。

在2023財年和2022財年,我們的前十大客戶分別貢獻了我們收入的53.7%和56.3%。因此,我們的財務業績與相對少數客戶的支出密切相關,並可能受到影響這些客戶業務的市場、行業或競爭動態的重大影響。我們對數量相對較少的客戶的依賴增加了我們對他們的支出水平、網絡優先級和購買策略變化的風險敞口。一個重要客戶的流失可能會對我們的業務和運營結果產生實質性的不利影響,我們的運營結果可能會按季度波動,具體取決於與這些大客戶的銷售量和採購優先順序。在2023財年,我們對雲提供商客戶的銷售額爲56140美元萬,佔總收入的12.8%。2023財年,AT&T的銷售額爲46470美元萬,佔總收入的10.6%;2022財年,AT&T的銷售額爲43340美元萬,佔總收入的11.9%。威瑞森在2022財年的萬收入爲40280美元,佔總收入的11.1%。在2023財年或2022財年,沒有其他客戶的收入佔我們收入的10%以上。

雖然帶寬增長和網絡演變的驅動力仍然強勁,但我們的許多網絡運營商客戶面臨着限制資本支出預算的壓力,他們的企業無法以帶寬增長的速度增長網絡支出。因此,當我們創新和引入新的、更強大的解決方案以增加容量或添加功能時,市場期望比現有或競爭解決方案更具成本效益的解決方案,並且新產品始終提供更低的每位性能價格。這種常規的技術驅動的價格壓縮、我們市場的價格競爭以及客戶管理網絡成本的持續努力的結合可能會影響我們的增長率,並要求我們增加產品出貨量以維持和增長收入。

銷售成本和毛利潤

所售商品的產品成本主要包括支付給第三方合同製造商的金額、零部件成本、與製造相關的運營、保修和其他合同義務相關的運輸和物流成本、特許權使用費、許可費、無形資產攤銷、超額和過時庫存成本以及(如適用)承諾客戶合同的估計損失。

所售商品的服務成本主要包括與我們提供服務(包括安裝、部署、維護支持、諮詢和培訓活動)相關的直接和第三方成本,以及(在適用時)承諾客戶合同的估計損失。其中大部分成本與人員有關,包括員工和第三方承包商相關成本。

我們的毛利潤佔收入的百分比,或「毛利率」,可能會因許多因素而波動,特別是在季度基礎上。我們的毛利率可能會波動,並受到不利影響,這取決於我們在特定細分市場、產品線、地理位置或客戶中的收入集中度,包括我們在特定時期銷售軟件的成功。相對於我們在市場上經常遇到的價格侵蝕,我們的毛利率仍然高度依賴於我們繼續推動年度產品成本下降的能力。這可能具有挑戰性,尤其是在當前供應有限的環境下。此外,我們經常被要求與激進的價格和商業條款競爭,爲了確保與新客戶和現有客戶的業務,我們可能會同意對毛利率產生不利影響的定價或其他不利的商業條款。如果成功奪取市場份額並贏得新業務,這些定價動態和網絡部署的早期階段可能會給毛利率帶來額外壓力。新網絡建設的早期階段通常還包括更加集中較低利潤率的「通用」設備、光電子銷售和安裝服務,目的是提高利潤率,因爲我們向客戶銷售通道卡和維護服務,因爲他們增加了容量並需要監控他們的網絡。與利潤率更高的現有解決方案相比,基於技術的價格壓縮以及引入或替代性價比更高的新平台可能會影響毛利率。毛利率也可能受到超額和過時庫存和保修義務費用變化的影響。

服務毛利率可能受到客戶和服務組合的影響,特別是部署和維護服務之間的組合、地理組合以及支持該業務的內部資源投資的時間和程度。

Currency Fluctuations

During fiscal 2023, approximately 49.4% of our operating expense was non-U.S. Dollar denominated, including Canadian Dollars, Indian Rupees, and Euros. During fiscal 2023 as compared to fiscal 2022, the U.S. Dollar primarily strengthened against these and other currencies. Consequently, our operating expense reported in U.S. Dollars decreased by approximately $23.3 million, or 1.5%, net of hedging.

Operating expense increased in fiscal 2023 from the level reported for fiscal 2022, primarily due to increases in employee headcount and variable compensation costs associated with our annual cash incentive compensation plan and increases in professional services. We have also experienced, and are continuing to experience, increases in the cost of labor and other costs of doing business due to inflation, and continued inflationary pressures could have an adverse impact on our profitability. We

Table of Contents
expect operating expense to continue to increase from the level reported in fiscal 2023 primarily due to planned investment in research and development to advance our strategy and higher employee compensation costs.
Operating expense consists of the component elements described below.

Research and development expense primarily consists of salaries and related employee expense (including share-based compensation expense), prototype costs relating to design, development, product testing, depreciation expense, and third-party consulting costs.

Selling and marketing expense primarily consists of salaries, commissions and related employee expense (including share-based compensation expense) and sales and marketing support expense, including travel, demonstration units, trade show expense, and third-party consulting costs.

General and administrative expense primarily consists of salaries and related employee expense (including share-based compensation expense) and costs for third-party consulting and other services.

Significant asset impairments and restructuring costs primarily reflect actions we have taken to improve the alignment of our workforce, facilities and operating costs with perceived market opportunities, business strategies, changes in market and business conditions, the redesign of certain business processes and significant impairments of assets.

Amortization of intangible assets primarily reflects the amortization of both purchased technology and the value of customer relationships derived from our acquisitions.

Acquisition and integration costs primarily consist of expenses for financial, legal and accounting advisors and severance and other employee-related costs, associated with our acquisition activity. For more information on our acquisitions, see Note 4 to our Consolidated Financial Statements included in Item 8 of Part II of this report.

Research and development expense benefited from $16.3 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 $125.9 million. This increase primarily reflects increases in employee headcount and related compensation costs including variable compensation costs associated with our annual cash incentive compensation plan, and professional services related to design engineering, fabrication and production of ASIC chips. The increase in employee headcount was partially due to our acquisitions of Benu and Tibit.
Selling and marketing expense benefited from $5.4 million as a result of foreign exchange rates, primarily due to a stronger U.S. Dollar in relation to the Canadian Dollar and the Euro. Including the effect of foreign exchange rates, sales and marketing expense increased by $24.2 million. This increase primarily reflects increases in travel and entertainment costs, professional services and employee-related compensation costs primarily related to higher costs associated with our annual cash incentive compensation plan.

General and administrative expense benefited from $1.6 million as a result of foreign exchange rates, primarily due to a stronger U.S. Dollar in relation to the Canadian Dollar and Indian Rupee. Including the effect of foreign exchange rates, general and administrative expense increased by $35.9 million. This increase primarily reflects increases in employee-related compensation costs primarily related to higher costs associated with our annual cash incentive compensation plan, costs incurred as a result of the settlement of certain patent infringement claims and the resolution of related legal proceedings, and professional services.
Significant asset impairments and restructuring costs decreased by $10.0 million. This decrease primarily reflects the effect of a $3.8 million impairment charge due to our suspended operations in Russia recorded in fiscal 2022 and lower costs on 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 $4.8 million reflecting 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 increased by $2.9 million and primarily reflect financial, legal, and accounting advisors and employee-related costs related to our acquisitions of Benu and Tibit.

**Denotes % change from 2022 to 2023
Interest and other income (loss), net increased by $55.3 million, primarily resulting from higher interest income on our investments and 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. These increases were partially offset by foreign currency exchange gains (losses), net of foreign currency hedging impact. For more information on our acquisition of Tibit, see Note 4 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.
Interest expense increased, primarily due to additional indebtedness, including the 2030 Term Loan entered into during the first quarter of fiscal 2023, and increased interest on the unhedged portion of the 2025 Term Loan, 2030 Term Loan and 2030 New Term Loan (as defined below), primarily due to higher interest rates. For more information on our short-term and long-term debt, see Note 19 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.
Loss on extinguishment and modification of debt primarily reflects $1.9 million of extinguishment of debt costs and $6.0 million in debt modification costs, both related to our term loan refinancing which occurred in the fourth quarter of fiscal 2023. For more information, see Note 19 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.
Provision (benefit) for income taxes increased by $39.2 million, primarily due to the increase in pre-tax income in fiscal 2023. The effective tax rate for fiscal 2023 was higher than the effective tax rate for fiscal 2022, primarily due to the mandatory capitalization of research and development expenses in fiscal 2023.

Blue Planet Automation Software and Services segment loss increased by $11.3 million, primarily due to lower sales volume, increased research and development costs and lower gross margin on software-related services, as described above.
Global Services segment profit decreased by $14.3 million, primarily due to higher incremental costs on maintenance related support and lower maintenance support and training revenue, as described above.

Liquidity and Capital Resources
Overview. For the fiscal year ended October 28, 2023, we generated $168.3 million of cash from operations, as our net income (adjusted for non-cash charges) of $565.1 million exceeded our working capital requirements of $396.8 million. For additional details on our cash used in operating activities, see the discussion below under the caption “Cash Provided by Operating Activities.”
Cash, cash equivalents and investments increased by $65.9 million during fiscal 2023. Cash from operations was partially offset by the following: (i) cash used for stock repurchases under our stock repurchase program of $242.2 million; (ii) cash used for the acquisition of businesses of $230.0 million, net of cash acquired; (iii) cash used to fund our investing activities for capital expenditures totaling $106.2 million; (iv) stock repurchased upon vesting of our stock unit awards to employees relating to tax withholding of $38.5 million; and (v) cash used for payments on our term loans of $9.4 million. In addition to cash provided by operations, the following items also contributed to the increase in cash: (i) proceeds from the issuance of the 2030 Term Loan, which provided $492.5 million in cash, net of paid debt issuance costs; and (ii) issuance of equity under our employee stock purchase plans which provided $31.4 million in cash during fiscal 2023.
See Notes 4, 19, and 22 to our Consolidated Financial Statements included in Item 8 of Part II of this report for information relating to these transactions.

Our principal sources of liquidity include our cash, cash equivalents and investments, which as of October 28, 2023 totaled $1.2 billion, as well as the unused portion of the Revolving Credit Facility. The Revolving Credit Facility, which we and certain of our subsidiaries entered into on October 24, 2023, replaced the ABL Credit Facility and 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 October 28, 2023, letters of credit totaling $72.5 million were outstanding under our Revolving Credit Facility. There were no borrowings outstanding under the Revolving Credit Facility as of October 28, 2023.
Foreign Liquidity. The amount of cash, cash equivalents and short-term investments held by our foreign subsidiaries was $308.0 million as of October 28, 2023. During the fourth quarter of fiscal 2023, we evaluated the undistributed earnings of the foreign subsidiaries and identified approximately $222.0 million in earnings that we no longer consider to be indefinitely reinvested. We have recorded a provision of $2.5 million that reflects the income tax effects of the repatriation of these earnings. No additional income tax expense has been provided for any remaining undistributed foreign earnings, or any additional outside basis difference inherent in our foreign subsidiaries, as these amounts continue to be indefinitely reinvested. See Note 23 to our Consolidated Financial Statements included in Item 8 of Part II of this report.
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 fiscal 2023, we repurchased an additional $250.0 million of our common stock under the stock repurchase program, and we had $250.0 million remaining under the current repurchase authorization as of October 28, 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 22 to our Consolidated Financial Statements included in Item 8 of Part II 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 have historically been successful in our ability to secure such sources of financing; however, our access to these sources of capital could be materially and adversely impacted, and we may not be able to receive terms as favorable as we have historically received, whether due to inflation or other factors. We regularly evaluate alternatives to manage our capital structure and market opportunities to enhance our liquidity and provide further operational and strategic flexibility.

As compared to the end of fiscal 2022:
The $94.6 million of cash used in accounts receivable during fiscal 2023 primarily reflects increased sales volume in the fourth quarter of fiscal 2023;
The $132.5 million of cash used in inventory during fiscal 2023 related to 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 $52.0 million of cash used in prepaid expenses and other during fiscal 2023 primarily reflects increases in prepaid value added taxes;
The $138.5 million of cash used in accounts payable, accruals and other obligations during fiscal 2023 primarily reflects the timing of payments to suppliers, partially offset by a higher accrual rate related to Ciena’s 2023 annual cash incentive compensation plan;
The $27.4 million of cash provided by deferred revenue during fiscal 2023 represents an increase in advanced payments received on multi-year maintenance contracts from customers prior to revenue recognition; and
The $6.7 million of cash used in operating lease assets and liabilities, net, during fiscal 2023 represents cash paid for operating lease payments in excess of operating lease costs. For more details, see Note 18 to our Consolidated Financial Statements included in Item 8 of Part II of this report.
Our days sales outstanding (“DSOs”) were 95 for fiscal 2023, as compared to 107 for fiscal 2022. The calculation of DSOs includes accounts receivable, net and contract assets for unbilled receivables, net included in prepaid expenses and other. Our inventory turns slightly increased from 1.8 during fiscal 2022 to 2.0 during fiscal 2023 due to the supply chain beginning to stabilize as described above.

(1) The 2025 Term Loan bore interest at LIBOR for the chosen borrowing period plus a spread of 1.75% subject to a minimum LIBOR rate of 0.00% prior to its amendment on January 19, 2023, and then bore interest at SOFR for the chosen borrowing period plus a spread of 1.75% subject to a minimum SOFR rate of 0.00%. The 2025 Term Loan was terminated on October 24, 2023.
(2) The 2030 Term Loan bore interest at SOFR for the chosen borrowing period plus a spread of 2.50% subject to a minimum SOFR rate of 0.00%. The 2030 Term Loan was terminated on October 24, 2023.
(3) Interest on the 2030 New Term Loan is payable periodically based on the interest period selected for borrowing. The 2030 New Term Loan bears interest at SOFR for the chosen borrowing period plus a spread of 2.00% subject to a minimum SOFR rate of 0.00%. At the end of fiscal 2023, the interest rate on the 2030 New Term Loan was 7.33%.
(4) The 2030 Senior Notes bear interest at a rate of 4.00% per annum and mature on January 31, 2030. Interest on the 2030 Notes is payable semiannually on January 31 and July 31 of each year.
(5) Our interest rate swaps fix the SOFR rate for $350.0 million of our Term Loans at 3.47% through January 2028 and another $350.0 million of our Term Loans at 2.968% through September 2025. In January 2023, we entered into a LIBOR to SOFR basis swap (“basis swap”). The basis swap and our LIBOR interest rate swaps, which matured in September 2023, fixed the SOFR rate for $350.0 million of our Term Loans at 2.883% from January to September 2023.
(6) During fiscal 2023, we issued certain standby letters of credit under the Revolving Credit Facility and its predecessor, the ABL Credit Facility and paid $2.1 million in commitment fees, interest expense and other administrative charges primarily relating to the ABL Credit Facility. The ABL Credit Facility was terminated on October 24, 2023.

For additional information about our short-term and long-term debt, revolving credit facilities and derivative instruments, see Notes 16, 19 and 20 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report and Item 7A of Part II of this annual report.

Contractual Obligations
Debt. As of October 28, 2023, we had $1.2 billion outstanding principal associated with our 2030 New Term Loan, with $8.8 million maturing within 12 months. Interest payments on the 2030 New Term Loan and payments to be received under the interest rate swaps are variable and are calculated using the interest rate in effect as of the October 28, 2023. Future interest payments associated with the 2030 New Term Loan totaled $589.7 million, with $87.2 million payable within 12 months. As of October 28, 2023, we had $400.0 million outstanding principal associated with the 2030 Notes payable January 31, 2030. Future interest payments associated with the 2030 Notes totaled $104.0 million, with $16.0 million payable within 12 months. Future interest payments to be received net of payments under the interest rate swaps totaled $44.4 million, with $15.1 million to be received within 12 months. For additional information about our short-term and long-term debt and interest rate swaps, see Notes 16 and 19 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report and Item 7A of Part II of this annual report.
Purchase Order Obligations. As of October 28, 2023, we had $1.7 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.
Leases. We have lease arrangements for facilities including research and development centers, engineering facilities and smaller offices in regions throughout the world to support sales and services operations. Office facilities are leased under various non-cancelable operating or finance leases. As of October 28, 2023, we had fixed lease payment obligations of $125.7 million, with $25.8 million payable within 12 months. See Note 18 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.

Off-Balance Sheet Arrangements
We do not engage in any off-balance sheet financing arrangements. In particular, we do not have any equity interests in so-called limited purpose entities, which include special purpose entities (SPEs) and structured finance entities.

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. Note 1 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report describes the significant accounting
59

Table of Contents
policies and methods used in the preparation of the Consolidated Financial Statements. 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 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. 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.

We believe that the following critical accounting policies reflect those areas where significant judgments and estimates are used in the preparation of our consolidated financial statements.

Revenue Recognition

Revenue is allocated among performance obligations based on standalone selling price (“SSP”). SSP reflects the price at which we would expect to sell that product or service on a stand-alone basis at contract inception and that we would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when we sell the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, we determine SSP using information that may include market conditions and other observable inputs.

We apply judgment in determining the transaction price, as we may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that we offer to our distributors, partners and customers. When determining the amount of revenue to recognize, we estimate the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. We also consider any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.

When transfer of control is judged to be over time for installation and professional service arrangements, we apply the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, we recognize revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed.

Our total deferred revenue for products was $28.4 million and $19.8 million as of October 28, 2023 and October 29, 2022, respectively. Our services revenue is deferred and recognized ratably over the period during which the services are to be performed. Our total deferred revenue for services was $200.1 million and $180.4 million as of October 28, 2023 and October 29, 2022, respectively.

Business Combinations

We record acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed in order to allocate purchase price consideration properly between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Our estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Our significant assumptions and estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur that may affect the accuracy or validity of such estimates. During fiscal 2022, we completed the acquisitions of AT&T’s Vyatta Software Technology (“Vyatta”) and Xelic, Inc. (“Xelic”) for an aggregate purchase price of $64.1 million. During fiscal 2023, we completed the acquisitions of Benu and Tibit for an aggregate purchase price of $291.7 million. See Note 4 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for more information regarding these transactions.

Share-Based Compensation

We estimate the fair value of our restricted stock unit awards based on the fair value of our common stock on the date of grant. Our outstanding restricted stock unit awards are subject to service-based vesting conditions and/or performance-based vesting conditions. We recognize the estimated fair value of service-based awards as share-based expense ratably over the vesting period on a straight-line basis. Awards with performance-based vesting conditions require the achievement of certain financial or other performance criteria or targets as a condition to the vesting, or acceleration of vesting. We recognize the estimated fair value of performance-based awards as share-based expense over the performance period, using graded vesting, which considers each performance period or tranche separately, based on our determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, we reassess the probability of achieving the performance targets and the performance period required to meet those targets, and the expense is adjusted accordingly. Determining whether the performance targets will be achieved involves judgment, and the estimate of expense may be revised periodically based on changes in the probability of achieving the performance targets. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation cost is reversed.

Share-based compensation expense is taken into account based on awards granted. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. Reversal of share-based compensation expense based on forfeitures can materially affect the measurement of estimated fair value of our share-based compensation. See Note 24 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information regarding our assumptions related to share-based compensation and the amount of share-based compensation expense we incurred for the periods covered in this report. As of October 28, 2023, total unrecognized compensation expense was $201.0 million, which relates to unvested restricted stock units and is expected to be recognized over a weighted-average period of 1.39 years.

We are required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled.

Reserve for Inventory Obsolescence

We make estimates about future customer demand for our products when establishing the appropriate reserve for excess and obsolete inventory. For fiscal 2023, future demand was calculated using both customer backlog and future forecasted sales. For fiscal 2022, future demand was calculated primarily based on customer backlog. Generally, our customers may cancel or change their orders with limited advance notice, or they may decide not to accept our products and services, although instances of both cancellation and non-acceptance are rare. We write down inventory that has become obsolete or unmarketable 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 our strategic direction, discontinuance of a product or introduction of newer versions of our products, declines in the sales of or forecasted demand for certain products, and general market conditions. Inventory write downs are a component of our product cost of goods sold. Upon recognition of the write down, a new lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis. In an effort to limit our exposure to delivery delays and to satisfy customer needs, we purchase inventory based on forecasted sales across our product lines. Beginning in the second half of fiscal 2021, we started placing significant, advanced orders for supply of certain long lead time components to address our expected customer demand for fiscal 2022 and the then-emerging supply chain challenges. During the second half of fiscal 2023, supply for certain long lead time components began to stabilize and the need to place advance orders decreased for these components. As of October 28, 2023 and October 29, 2022, we had $1.7 billion and $2.6 billion, respectively, in outstanding purchase order commitments to our contract manufacturers and component suppliers for inventory. In addition, part of our research and development strategy is to promote the convergence of similar features and functionalities across our product lines. Each of these practices exposes us to the risk that our customers will not order products for which we have forecasted sales, or will purchase less than we have forecasted.

We recorded charges for excess and obsolete inventory of $29.5 million, $16.2 million and $17.9 million in fiscal 2023, 2022 and 2021, respectively. Our inventory, net of allowance for excess and obsolescence, was $1.1 billion and $946.7 million as of October 28, 2023 and October 29, 2022, respectively.

Allowance for Credit Losses for Accounts Receivable and Contract Assets

We estimate our allowances for credit losses using relevant available information from internal and external sources. This information is related to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. When assessing for credit losses, we determine
61

Table of Contents
collectability by pooling assets with similar characteristics. The allowances for credit losses are each measured on a collective basis when similar risk characteristics exist. The allowances for credit losses are each measured by multiplying the exposure probability of default (the probability that the asset will default within a given time frame) by the loss given default rate (the percentage of the asset not expected to be collected due to default) based on the pool of assets.

Probability of default rates is published by third-party credit rating agencies. Adjustments to our exposure probability may take into account a number of factors, including, but not limited to, various customer-specific factors, the potential sovereign risk of the geographic locations in which the customer is operating and macroeconomic conditions. These factors are updated regularly or when facts and circumstances indicate that an update is deemed necessary.

Our accounts receivable, net of allowance for credit losses, was $1.0 billion and $920.8 million as of October 28, 2023 and October 29, 2022, respectively. Our allowance for credit losses was $11.7 million and $11.0 million as of October 28, 2023 and October 29, 2022, respectively.

Our contract assets for unbilled accounts receivable, net of allowance for credit losses, was $150.3 million and $156.0 million as of October 28, 2023 and October 29, 2022, respectively. Our allowance for credit losses was $0.1 million and $0.2 million as of October 28, 2023 and October 29, 2022, respectively.

Goodwill
        
Our goodwill was generated from the acquisitions of (i) Cyan, Inc. during fiscal 2015, (ii) the high-speed photonics components assets of TeraXion, Inc. during fiscal 2016, (iii) Packet Design, LLC and DonRiver Holdings, LLC during fiscal 2019, (iv) Centina Systems, Inc. during fiscal 2020, (v) Vyatta and Xelic during fiscal 2022 and (vi) Benu and Tibit during fiscal 2023. The goodwill from these acquisitions is primarily related to expected economic synergies. Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. We test goodwill for impairment on an annual basis, which we have determined to be as of the last business day of fiscal September each year. We also test goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.

We test goodwill impairment by comparing the fair value of the reporting unit with the unit’s carrying amount, including goodwill. Goodwill is allocated to reporting units based on relative fair value using a discounted cash flow model. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If we are required to take a substantial impairment charge, our operating results would be materially adversely affected in such period. As of October 28, 2023 and October 29, 2022, the goodwill balance was $444.8 million and $328.3 million, respectively. There were no goodwill impairments resulting from our fiscal 2023 and 2022 impairment tests and no reporting unit was determined to be at risk of failing the goodwill impairment test. See Note 14 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.

Long-lived Assets

Our long-lived assets include equipment, building, furniture and fixtures, operating right-of-use assets, finite-lived intangible assets and maintenance spares. As of October 28, 2023 and October 29, 2022, these assets totaled $575.0 million and $427.2 million, net, respectively. We test long-lived assets for impairment whenever triggering events or changes in circumstances indicate that the assets’ carrying amount is not recoverable from its undiscounted cash flows. Our long-lived assets are assigned to asset groups which represent the lowest level for which we identify cash flows. We measure impairment loss as the amount by which the carrying amount of the asset or asset group exceeds its fair value.

Deferred Tax Assets

Pursuant to ASC Topic 740, Income Taxes, we maintain a valuation allowance for a deferred tax asset when it is deemed to be more likely than not that some or all of the deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent on the generation of future taxable income (including the reversals of deferred tax liabilities) during the periods in which those deferred tax assets will become deductible. In evaluating whether a valuation allowance is required under such rules, we consider all available positive and negative evidence, including prior operating results, the nature and reason for any losses, our forecast of future taxable income, utilization of tax planning strategies, and the dates on which any deferred tax assets are expected to expire. These assumptions and estimates require a significant amount of judgment and are made based on current and projected circumstances and conditions.

62

Table of Contents
Quarterly, we perform an analysis to determine the likelihood of realizing our deferred tax assets and whether sufficient evidence exists to support reversal of all or a portion of the valuation allowance. The valuation allowance balances at October 28, 2023 and October 29, 2022 were $189.9 million and $162.1 million, respectively. The corresponding net deferred tax assets were $809.3 million and $824.0 million, respectively. We will continue to evaluate future financial performance to determine whether such performance is both sustained and significant enough to provide sufficient evidence to support reversal of all or a portion of the remaining valuation allowance. The value of our net deferred tax asset may be subject to change in the future, depending on our generation or projections of future taxable income, as well as changes in tax policy or our tax planning strategy.

During fiscal 2021, we completed an internal transfer of certain of our non-U.S. intangible assets, which created amortizable tax basis resulting in the discrete recognition of a $119.3 million deferred tax asset with a corresponding tax benefit. The recognition of the deferred tax asset from the internal transfer of the non-U.S. intangible assets requires management to make estimates and assumptions to determine the fair value of the intangible assets transferred and significant judgments in evaluating the application of tax laws in the applicable jurisdictions, including where the deferred tax asset will be recovered. Estimates in valuing the intangible assets include, but are not limited to, internal revenue and expense forecasts, the estimated life of the intangible assets, and discount rates, which are affected by expectations about future market or economic conditions. Although we believe the assumptions and estimates that we have made are reasonable and appropriate, they are based, in part, on historical experience and are inherently uncertain.

For further discussion, see Note 23 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.

Warranty

Our liability for product warranties, included in accrued liabilities and other short-term obligations, was $57.1 million and $45.5 million as of October 28, 2023 and October 29, 2022, respectively. Our products are generally covered by a warranty for periods ranging from one to five years. We accrue for warranty costs as part of our cost of goods sold based on associated material costs, technical support labor costs and associated overhead. Material cost is estimated based primarily on historical trends in the volume of product returns within the warranty period and the cost to repair or replace the equipment. Technical support labor cost is estimated based primarily on historical trends and the cost to support customer repairs within the warranty period. The provision for product warranties, net of adjustments for previous years’ provisions, was $31.7 million, $17.4 million and $17.1 million for fiscal 2023, 2022 and 2021, respectively. The provision for warranty claims may fluctuate on a quarterly basis depending on the mix of products and customers in that period. If actual product failure rates, material replacement costs, service or labor costs differ from our estimates, revisions to the estimated warranty provision would be required. See Note 15 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk related to changes in interest rates and foreign currency exchange rates. The following discussion about these market risks includes forward-looking statements. Actual results could differ materially from those projected in these forward-looking statements.

Interest Rate Sensitivity. We maintain an investment portfolio of various holdings, types, and maturities. See Notes 7 and 8 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report for information relating to investments and fair value. These investments are sensitive to interest rate movements, and their fair value will decline as interest rates rise and increase as interest rates decline. The estimated impact on these investments of a 100 basis point (1.0%) increase in interest rates across the yield curve from rates in effect as of the balance sheet date would be a $2.3 million decline in value.

Our earnings and cash flows from operations would be exposed to changes in interest rates because of the floating rate of interest on our 2030 New Term Loan if such loan were not hedged using floating-to-fixed rate interest rate swaps. See Note 16 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report. We have entered into interest rate swaps that fix the floating rate for $350.0 million of our floating rate debt at 2.968% from September 2023 through September 2025, and another $350.0 million of our floating rate debt at 3.47% from January 2023 through January 2028. As such, a 100 basis point (1.0%) increase in the SOFR rate as of our most recent SOFR rate setting would increase our annualized interest expense by approximately $4.7 million on the unhedged portion of our 2030 New Term Loan as recognized in our Consolidated Financial Statements.

Foreign Currency Exchange Risk. As a global concern, our business and results of operations are exposed to and can be impacted by movements in foreign currency exchange rates. Because we sell globally, some of our sales transactions and revenue are non-U.S. Dollar denominated, with the Euro, Canadian Dollar and British Pound being our most significant foreign currency revenue exposures. If the U.S. Dollar strengthens against these currencies, our revenue for these transactions reported in U.S. Dollars would decline. For our U.S. Dollar denominated sales, an increase in the value of the U.S. Dollar would increase the real costs of our products to customers in markets outside the United States, which could impact our competitive position. During fiscal 2023, approximately 14.9% of revenue was non-U.S. Dollar denominated. During fiscal 2023 as compared to fiscal 2022, the U.S. Dollar primarily strengthened against a number of foreign currencies. Consequently, our revenue reported in U.S. Dollars was adversely impacted by approximately $4.7 million or 0.1%. As it relates to costs of goods sold, employee-related and facilities costs associated with certain manufacturing-related operations in Canada represent our primary exposure to foreign currency exchange risk.

With regard to operating expense, our primary exposure to foreign currency exchange risk relates to the Canadian Dollar, Indian Rupee and Euro. During fiscal 2023, approximately 49.4% of our operating expense was non-U.S. Dollar denominated. If these foreign currencies strengthen against the U.S. Dollar, costs reported in U.S. Dollars will increase. During fiscal 2023 as compared to fiscal 2022, the U.S. Dollar primarily strengthened against these and other currencies. Consequently, our operating expense reported in U.S. Dollars decreased by approximately $23.3 million, or 1.5%, net of hedging impact.

From time to time, we use foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less and are designated as cash flow hedges. At the inception of the cash flow hedge, and on an ongoing basis, we assess whether the forward contract has been effective in offsetting changes in cash flows attributable to the hedged risk during the hedging period. The derivative’s net gain or loss is initially reported as a component of accumulated other comprehensive loss and, upon the occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statements of Operations to which the hedged transaction relates.

During fiscal 2023, we recorded $0.4 million in foreign currency exchange losses, as a result of monetary assets and liabilities that were transacted in a currency other than the entity’s functional currency, and the re-measurement adjustments were recorded in interest and other income (loss), net on our Consolidated Statements of Operations. From time to time, we use foreign currency forwards to hedge these balance sheet exposures. 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 (loss), net. During fiscal 2023, we recorded losses on non-hedge designated foreign currency forward contracts of $3.9 million. See Notes 1, 6 and 16 to our Consolidated Financial Statements included in Item 8 of Part II of this annual report.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Ciena Corporation

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Ciena Corporation and its subsidiaries (the “Company”) as of October 28, 2023 and October 29, 2022, and the related consolidated statements of operations, of comprehensive income, of changes in stockholders’ equity and of cash flows for each of the three years in the period ended October 28, 2023, including the related notes (collectively referred to as the “consolidated financial statements”). We also have audited the Company's internal control over financial reporting as of October 28, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of October 28, 2023 and October 29, 2022, and the results of its operations and its cash flows for each of the three years in the period ended October 28, 2023 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of October 28, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the Report of Management on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company's internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that
(i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Reserve for Excess and Obsolete Inventory

As described in Notes 1 and 10 to the consolidated financial statements, the Company’s consolidated inventory balance, net of the allowance for excess and obsolescence, was $1.1 billion as of October 28, 2023. Management records a provision for excess and obsolete inventory when an impairment has been identified and has a reserve for excess and obsolete inventory of $50.0 million as of October 28, 2023. Management 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 the Company’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.

The principal considerations for our determination that performing procedures relating to the reserve for excess and obsolete inventory is a critical audit matter are the significant judgment by management when developing their estimate, which in turn led to a high degree of auditor judgment, subjectivity, and effort to perform procedures and evaluate the audit evidence obtained relating to the assumptions regarding future demand.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the Company’s evaluation of the reserve for excess and obsolete inventory, including controls over the assumptions used within the model. These procedures also included, among others, testing management’s process for determining the reserve for excess and obsolete inventory. This included evaluating the appropriateness of the inventory reserve model and the reasonableness of the significant assumptions relating to the future demand. Evaluating the assumptions related to future demand involved evaluating whether the assumptions used were reasonable considering historical sales and expectations regarding future sales. Testing management's process for determining future demand included procedures to evaluate the reliability, completeness and relevance of management's data used in the future demand assumption. Testing the relevance and reliability of the data included evaluating the reasonableness of the long-term sales forecasts and historical activity.

Basis of Presentation

The accompanying consolidated financial statements include the accounts of Ciena and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Ciena has a 52 or 53-week fiscal year, which ends on the Saturday nearest to the last day of October in each year (October 28, 2023, October 29, 2022, and October 30, 2021, for the periods reported). Fiscal 2023, fiscal 2022 and fiscal 2021 each consisted of a 52-week fiscal year.

Business Combinations

Ciena records acquisitions using the purchase method of accounting. All of the assets acquired, liabilities assumed, contractual contingencies and contingent consideration are recognized at their fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net tangible and net intangible assets acquired is recorded as goodwill. The application of the purchase method of accounting for business combinations requires management to make significant estimates and assumptions in the determination of the fair value of assets acquired and liabilities assumed, in order to properly allocate purchase price consideration between assets that are depreciated and amortized from goodwill. These assumptions and estimates include a market participant’s use of the asset and the appropriate discount rates for a market participant. Ciena’s estimates are based on historical experience, information obtained from the management of the acquired companies and, when appropriate, include assistance from independent third-party appraisal firms. Significant assumptions and
73

Table of Contents
estimates can include, but are not limited to, the cash flows that an asset is expected to generate in the future, the appropriate weighted-average cost of capital and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and unpredictable. In addition, unanticipated events and circumstances may occur which may affect the accuracy or validity of such estimates.
Use of Estimates

The preparation of the financial statements and related disclosures in conformity with Generally Accepted Accounting Principles (“GAAP”) requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used for selling prices for multiple element arrangements, shared-based compensation, bad debts, valuation of inventories and investments, recoverability of intangible assets, other long-lived assets and goodwill, income taxes, warranty obligations, restructuring liabilities, derivatives, contingencies and litigation. Ciena bases its estimates on historical experience and assumptions that it believes are reasonable. Actual results may differ materially from management’s estimates.

Cash and Cash Equivalents

Ciena considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Any restricted cash collateralizing letters of credit is included in other current assets and other long-term assets depending on the duration of the restriction.

Investments

Ciena’s investments in debt securities are classified as available-for-sale and reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive loss. Ciena recognizes losses in the income statement when it determines that declines in the fair value of its investments below their cost basis are other-than-temporary. In determining whether a decline in fair value is other-than-temporary, Ciena considers various factors, including market price (when available), investment ratings, the financial condition and near-term prospects of the investee, the length of time and the extent to which the fair value has been less than Ciena’s cost basis, and Ciena’s intent and ability to hold the investment until maturity or for a period of time sufficient to allow for any anticipated recovery in market value. Ciena considers all marketable debt securities that it expects to convert to cash within one year or less to be short-term investments, with all others considered to be long-term investments.

Ciena has minority equity investments in privately held technology companies that are classified in other long-term assets. These investments are carried at cost because Ciena owns less than 20% of the voting equity and does not have the ability to exercise significant influence over the company. Ciena monitors these investments for impairment and makes appropriate reductions to the carrying value when necessary. As of October 28, 2023, the combined carrying value of these investments was minimal. Ciena elects to estimate the fair value at cost minus impairment, if any, plus or minus observable price changes in orderly transactions for identical or similar investments of the same issuer. Ciena evaluates these investments for impairment or observable price changes quarterly and records adjustments to interest and other income (loss), net on the Consolidated Statements of Operations.

Inventories

Inventories are stated at the lower of cost or market, with cost computed using standard cost, which approximates actual cost, on a first-in, first-out basis. Ciena records a provision for excess and obsolete inventory when an impairment has been identified.

Segment Reporting

Ciena’s chief operating decision maker, its chief executive officer, evaluates the Company’s performance and allocates resources based on multiple factors, including measures of segment profit (loss). Operating segments are defined as components of an enterprise that engage in business activities that may earn revenue and incur expense, for which discrete financial information is available, and for which such information is evaluated regularly by the chief operating decision maker for purposes of allocating resources and assessing performance. Ciena has the following operating segments for reporting purposes: (i) Networking Platforms; (ii) Platform Software and Services; (iii) Blue Planet Automation Software and Services; and (iv) Global Services. See Note 25 below.

Goodwill
74

Table of Contents

Goodwill is the excess of the purchase price over the fair values assigned to the net assets acquired in a business combination. Ciena tests goodwill for impairment on an annual basis, which it has determined to be the last business day of fiscal September each year. Ciena also tests goodwill for impairment between annual tests if an event occurs or circumstances change that would, more likely than not, reduce the fair value of the reporting unit below its carrying value.

Annually, Ciena tests goodwill impairment qualitatively, or quantitatively by comparing the fair value of the reporting unit with the unit’s carrying amount, including goodwill. If this test indicates that the fair value is less than the carrying value, then an impairment loss is recognized limited to the total amount of goodwill allocated to that reporting unit. A non-cash goodwill impairment charge would have the effect of decreasing earnings or increasing losses in such period. If Ciena is required to take a substantial impairment charge, its operating results would be materially adversely affected in such period.

Long-lived Assets

Long-lived assets include equipment, building, furniture and fixtures, operating right-of-use (“ROU”) assets, finite-lived intangible assets and maintenance spares. Ciena tests long-lived assets for impairment whenever triggering events or changes in circumstances indicate that the asset’s carrying amount is not recoverable from its undiscounted cash flows. An impairment loss is measured as the amount by which the carrying amount of the asset or asset group exceeds its fair value. Ciena’s long-lived assets are assigned to asset groups that represent the lowest level for which cash flows can be identified.

Equipment, Building, Furniture and Fixtures and Internal Use Software

Equipment, building, furniture and fixtures are recorded at cost. Depreciation and amortization are computed using the straight-line method, generally over useful lives of three years to five years for equipment and furniture and fixtures and the shorter of useful life or lease term for leasehold improvements.    
    
Qualifying internal use software and website development costs incurred during the application development stage, which consist primarily of outside services and purchased software license costs, are capitalized and amortized straight-line over the estimated useful lives of two years to five years.

Leases

At the inception of a contract, Ciena must determine whether the contract is or contains a lease. The contract is or contains a lease if the contract conveys the right to control the use of the property, plant, or equipment for a designated term in exchange for consideration. Ciena’s evaluation of its contracts follows the assessment of whether there is a right to obtain substantially all of the economic benefits from the use and the right to direct the use of the identified asset in the contract. Operating leases are included in the Operating ROU assets, Operating lease liabilities and Long-term operating lease liabilities in the Consolidated Balance Sheets. Finance leases are included in Equipment, building, furniture and fixtures, net (“Finance ROU assets”), Accrued liabilities and other short-term obligations and Other long-term obligations in the Consolidated Balance Sheets.

Ciena has operating and finance leases that primarily relate to real property. Ciena has elected not to capitalize leases with a term of 12 months or less without a purchase option that it is likely to exercise. Ciena has elected not to separate lease and non-lease components of operating and finance leases. Lease components are payment items directly attributable to the use of the underlying asset, while non-lease components are explicit elements of a contract not directly related to the use of the underlying asset, including pass-through operating expenses like common area maintenance and utilities.

Operating ROU assets and lease liabilities and Finance ROU assets and lease liabilities are recognized on the Consolidated Balance Sheets at the present value of the future lease payments over the life of the lease term. Ciena uses discount rates based on incremental borrowing rates, on a collateralized basis, for the respective underlying assets, for terms similar to the respective leases when implicit rates for leases are not determinable. Operating lease costs are included as rent expense in the Consolidated Statements of Operations. Fixed base payments on operating leases paid directly to the lessor are recorded as lease expense on a straight-line basis. Related variable payments based on usage, changes in an index, or market rate are expensed as incurred. Finance ROU assets are generally amortized on a straight-line basis over the lease term with the interest expense on the lease liability recorded using the interest method. The amortization and interest expense are recorded separately in the Consolidated Statements of Operations.

Intangible Assets

75

Table of Contents
Ciena has recorded finite-lived intangible assets as a result of several acquisitions. Finite-lived intangible assets are carried at cost less accumulated amortization. Amortization is computed using the straight-line method over the expected economic lives of the respective assets, up to seven years, which approximates the use of intangible assets.

Cloud Computing Arrangements

Ciena capitalizes certain costs related to hosting arrangements that are service contracts (cloud computing arrangements). Capitalized costs are included in Other long-term assets in the Consolidated Balance Sheets and are amortized on a straight-line basis over the estimated useful life.

Maintenance Spares

Maintenance spares are recorded at cost. Ciena depreciates spares ratably over four years.

Concentrations

Substantially all of Ciena’s cash and cash equivalents are maintained at a small number of major U.S. financial institutions. The majority of Ciena’s cash equivalents consist of money market funds. Deposits held with banks may exceed the amount of insurance provided on such deposits. Because these deposits generally may be redeemed upon demand, management believes that they bear minimal risk.

Historically, a significant percentage of Ciena’s revenue has been concentrated among sales to a small number of large communications service providers and cloud providers. Consolidation among Ciena’s customers has increased this concentration. Consequently, Ciena’s accounts receivable are concentrated among these customers. See Note 2 below.

Additionally, Ciena’s access to certain materials or components is dependent on sole or limited source suppliers. The inability of any of these suppliers to fulfill Ciena’s supply requirements, or significant changes in supply cost, could affect future results. Ciena relies on a small number of contract manufacturers to perform the majority of the manufacturing for its products. If Ciena cannot effectively manage these manufacturers or forecast future demand, or if these manufacturers fail to deliver products or components on time, Ciena’s business and results of operations may suffer.

Revenue Recognition

Ciena recognizes revenue when control of the promised products or services is transferred to its customer, in an amount that reflects the consideration to which Ciena expects to be entitled in exchange for those products or services.

Ciena determines revenue recognition by applying the following five-step approach:

identification of the contract, or contracts, with a customer;
identification of the performance obligations in the contract;
determination of the transaction price;
allocation of the transaction price to the performance obligations in the contract; and
recognition of revenue when, or as, Ciena satisfies a performance obligation.

Generally, Ciena makes sales pursuant to purchase orders placed by customers under framework agreements that govern the general commercial terms and conditions of the sale of Ciena’s products and services. These purchase orders under framework agreements are used to determine the identification of the contract or contracts with this customer. Purchase orders typically include the description, quantity, and price of each product or service purchased. Purchase orders may include one-line bundled pricing for both products and services. Accordingly, purchase orders can include various combinations of products and services that are generally distinct and accounted for as separate performance obligations. Ciena evaluates each promised product and service offering to determine whether it represents a distinct performance obligation. In doing so, Ciena considers, among other things, customary business practices, whether the customer can benefit from the product or service on its own or together with other resources that are readily available, and whether Ciena’s commitment to transfer the product or service to the customer is separately identifiable from other obligations in the purchase order. For transactions where Ciena delivers the product or services, Ciena is typically the principal and records revenue and costs of goods sold on a gross basis.

Purchase orders are invoiced based on the terms set forth either in the purchase order or the framework agreement, as applicable. Generally, sales of products and software licenses are invoiced upon shipment or delivery. Maintenance and
76

Table of Contents
software subscription services are invoiced quarterly or annually in advance of the service term. Ciena’s other service offerings are generally invoiced upon completion of the service. Payment terms and cash received typically range from 30 to 90 days from the invoicing date. Historically, Ciena has not provided any material financing arrangements to its customers. As a practical expedient, Ciena does not adjust the amount of consideration it will receive for the effects of a significant financing component as it expects, at contract inception, that the period between Ciena’s transfer of the products or services to the customer and customer payment for the products or services will be one year or less. Shipping and handling fees invoiced to customers are included in revenue, with the associated expense included in product cost of goods sold. Ciena records revenue net of any associated sales taxes.

Ciena recognizes revenue upon the transfer of control of promised products or services to a customer. Transfer of control occurs once the customer has the contractual right to use the product, generally upon shipment or delivery to the customer. Transfer of control can also occur over time for services such as software subscription, maintenance, installation, and various professional services as the customer receives the benefit over the contract term.

Significant Judgments

Revenue is allocated among performance obligations based on standalone selling price (“SSP”). SSP reflects the price at which Ciena would expect to sell that product or service on a stand-alone basis at contract inception and that Ciena would expect to be entitled to receive for the promised products or services. SSP is estimated for each distinct performance obligation, and judgment may be required in its determination. The best evidence of SSP is the observable price of a product or service when Ciena sells the products separately in similar circumstances and to similar customers. In instances where SSP is not directly observable, Ciena determines SSP using information that may include market conditions and other observable inputs.

Ciena applies judgment in determining the transaction price, as Ciena may be required to estimate variable consideration when determining the amount of revenue to recognize. Variable consideration can include various rebate, cooperative marketing, and other incentive programs that Ciena offers to its distributors, partners and customers. When determining the amount of revenue to recognize, Ciena estimates the expected usage of these programs, applying the expected value or most likely estimate and updates the estimate at each reporting period as actual utilization data becomes available. Ciena also considers any customer right of return and any actual or potential payment of liquidated damages, contractual or similar penalties, or other claims for performance failures or delays in determining the transaction price, where applicable.

When transfer of control is judged to be over time for installation and professional service arrangements, Ciena applies the input method to determine the amount of revenue to be recognized in a given period. Utilizing the input method, Ciena recognizes revenue based on the ratio of actual costs incurred to date to the total estimated costs expected to be incurred. Revenue for software subscription and maintenance is recognized ratably over the period during which the services are performed.

Capitalized Contract Acquisition Costs

Ciena has considered the impact of the guidance in Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 340-40, Other Assets and Deferred Costs; Contracts with Customers, and the interpretations of the FASB Transition Resource Group for Revenue Recognition with respect to capitalization and amortization of incremental costs of obtaining a contract. In conjunction with this interpretation, Ciena considers each customer purchase in combination with the corresponding framework agreement, if applicable, as a contract. Ciena has elected to implement the practical expedient, which allows for incremental costs to be recognized as an expense when incurred if the period of the asset recognition is one year or less. If the period of the asset recognition is greater than one year, Ciena amortizes these costs over the period of performance. Ciena considers sales commissions incurred upon receipt of purchase orders placed by customers as incremental costs to obtain such purchase orders. The practical expedient method is applied to the purchase order as a whole and thus the capitalized costs of obtaining a purchase order is applied even if the purchase order contains more than one performance obligation. In cases where a purchase order includes various distinct products or services with both short-term (one year or less) and long-term (more than a year) performance periods, the cost of commissions incurred for the total value of the purchase order is capitalized and subsequently amortized as each performance obligation is recognized.

For the additional disclosures on capitalized contract acquisition costs, see Note 2 below.

Warranty Accruals

Ciena provides for the estimated costs to fulfill customer warranty obligations upon recognition of the related revenue. Estimated warranty costs include estimates for material costs, technical support labor costs and associated overhead. Warranty
77

Table of Contents
is included in cost of goods sold and is determined based on actual warranty cost experience, estimates of component failure rates and management’s industry experience. Ciena’s sales contracts do not permit the right of return of the product by the customer after the product has been accepted.

Allowance for Credit Losses for Accounts Receivable and Contract Assets

Ciena estimates its allowances for credit losses using relevant available information from internal and external sources, related to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. When assessing for credit losses, Ciena determines collectability by pooling assets with similar characteristics. The allowances for credit losses are each measured on a collective basis when similar risk characteristics exist. The allowances for credit losses are each measured by multiplying the exposure probability of default (the probability that the asset will default within a given time frame) by the loss given default rate (the percentage of the asset not expected to be collected due to default) based on the pool of assets.

Probability of default rates are published by third-party credit rating agencies. Adjustments to Ciena’s exposure probability may take into account a number of factors, including, but not limited to, various customer-specific factors, the potential sovereign risk of the geographic locations in which the customer is operating and macroeconomic conditions. These factors are updated regularly or when facts and circumstances indicate that an update is deemed necessary.

Accounts Receivable Factoring

Ciena has entered into factoring agreements to sell certain receivables to unrelated third-party financial institution on a non-recourse basis. These transactions are accounted for in accordance with ASC Topic 860, “Transfers and Servicing” and result in a reduction in accounts receivable because the agreements transfer effective control over, and risk related to, the receivables to the buyers. Ciena's factoring agreements do not allow for recourse in the event of uncollectability, and Ciena does not retain any interest in the underlying accounts receivable once sold. Trade accounts receivables balances sold are removed from the consolidated balance sheets and cash received is reflected as cash provided by (used in) operating activities in the Consolidated Statements of Cash Flow. Factoring related interest expense is recorded to interest and other income (loss), net on the Consolidated Statements of Operations. See Note 9 below.

Research and Development

Ciena charges all research and development costs to expense as incurred. Types of expense incurred in research and development include employee compensation, prototype equipment, consulting and third-party services, depreciation, facility costs and information technology.

Government Grants

Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Consolidated Statement of Operations to which the grant activity relates. See Notes 3 below.

Advertising Costs

Ciena expenses all advertising costs as incurred.

Legal Costs

Ciena expenses legal costs associated with litigation as incurred.

Table of Contents
Share-Based Compensation Expense

Ciena measures and recognizes compensation expense for share-based awards and employee stock purchases related to its Amended and Restated 2003 Employee Stock Purchase Plan (the “ESPP”) based on estimated fair values on the date of grant. Ciena estimates the fair value of employee stock purchases related to the ESPP using the Black-Scholes option-pricing model. Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. In each case, Ciena only recognizes expense in its Consolidated Statements of Operations for those restricted stock units that ultimately vest. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena’s total stockholder return as compared to an index of peer companies, in whole or in part. Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total stockholder return by assuming the satisfaction of any performance-based objectives at the “target” level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Ciena recognizes the estimated fair value of performance based awards subject to total stockholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model on the date of grant. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. See Note 24 below.

Stock Repurchase Program

Shares repurchased pursuant to Ciena’s stock repurchase program are immediately retired upon purchase. Repurchased common stock is reflected as a reduction of stockholders’ equity. Ciena’s accounting policy related to its share repurchases is to reduce its common stock based on the par value of the shares and to reduce its capital surplus for the excess of the repurchase price over the par value. Since the inception of its stock repurchase programs, Ciena has had an accumulated deficit balance; therefore, the excess over the par value has been applied to additional paid-in capital. Once Ciena has retained earnings, the excess will be charged entirely to retained earnings.

Income Taxes

Ciena accounts for income taxes using an asset and liability approach. This approach recognizes deferred tax assets and liabilities (“DTA”) for the expected future tax consequences attributable to differences between the carrying amounts of assets and liabilities for financial reporting purposes and their respective tax bases, and for operating loss and tax credit carryforwards. In estimating future tax consequences, Ciena considers all expected future events other than the enactment of changes in tax laws or rates. Valuation allowances are provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

In the ordinary course of business, transactions occur for which the ultimate outcome may be uncertain. In addition, tax authorities periodically audit Ciena’s income tax returns. These audits examine significant tax filing positions, including the timing and amounts of deductions and the allocation of income tax expenses among tax jurisdictions. Ciena is currently under audit in India for 2018 through 2021, in Canada for 2014, and in the United Kingdom for 2016 through 2021. Management does not expect the outcome of these audits to have a material adverse effect on Ciena’s consolidated financial position, results of operations or cash flows. Ciena’s major tax jurisdictions and the earliest open tax years are as follows: United States (2020), United Kingdom (2016), Canada (2014), and India (2018). Limited adjustments can be made to federal U.S. tax returns in earlier years in order to reduce net operating loss carryforwards. Ciena classifies interest and penalties related to uncertain tax positions as a component of income tax expense.

Ciena is required to record excess tax benefits or tax deficiencies related to stock-based compensation as income tax benefit or expense when share-based awards vest or are settled.

The Tax Cuts and Jobs Act (the “Tax Act”) includes provisions that affected Ciena starting in fiscal 2019, including a provision designed to tax global intangible low-taxed income (“GILTI”). An accounting policy choice is allowed to either treat taxes due on future U.S. inclusions related to GILTI in taxable income as a current-period expense when incurred (the “period cost method”) or factor such amounts into the measurement of deferred taxes (the “deferred method”). The calculation of the deferred balance with respect to the GILTI tax provisions will depend, in part, on analyzing global income to determine whether future U.S. inclusions in taxable income are expected related to GILTI and, if so, what the impact is expected to be. Ciena is electing to use the period cost method for future GILTI inclusions. Additionally, Ciena is electing to use the incremental cash tax savings approach when determining whether a valuation allowance needs to be recorded against the U.S. net operating loss (“NOL”) due to the GILTI inclusions. 

79

Table of Contents
The Tax Act also introduced an alternative tax known as the base erosion and anti-abuse tax (“BEAT”). An accounting policy choice has been made to consider BEAT as a period cost when incurred.

Loss Contingencies

Ciena is subject to the possibility of various losses arising in the ordinary course of business. These may relate to disputes, litigation and other legal actions. Ciena considers the likelihood of loss or the incurrence of a liability, as well as Ciena’s ability to estimate the amount of loss reasonably, in determining loss contingencies. An estimated loss contingency is accrued when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Ciena regularly evaluates current information available to it in order to determine whether any accruals should be adjusted and whether new accruals are required.

Fair Value of Financial Instruments

The carrying value of Ciena’s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair market value due to the relatively short period of time to maturity. For information related to the fair value of Ciena’s short-term and long-term debt, see Note 19 below.

Fair value for the measurement of financial assets and liabilities is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. Ciena utilizes a valuation hierarchy for disclosure of the inputs for fair value measurement. This hierarchy prioritizes the inputs into three broad levels as follows:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities;

Level 2 inputs are quoted prices for identical or similar assets or liabilities in less active markets or model-derived valuations in which significant inputs are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument; and

Level 3 inputs are unobservable inputs based on Ciena’s assumptions used to measure assets and liabilities at fair value. The fair values are determined based on model-based techniques using inputs Ciena could not corroborated with market data.

By distinguishing between inputs that are observable in the marketplace, and therefore more objective, and those that are unobservable, and therefore more subjective, the hierarchy is designed to indicate the relative reliability of the fair value measurements. A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

Restructuring

From time to time, Ciena takes actions to align its workforce, facilities and operating costs with perceived market opportunities, business strategies and changes in market and business conditions and redesign business processes. Ciena recognizes a liability for the cost associated with an exit or disposal activity in the period in which the liability is incurred, except for one-time employee termination benefits related to a service period, typically of more than 60 days, which are accrued over the service period. See Note 5 below.

Foreign Currency

Certain of Ciena’s foreign branch offices and subsidiaries use the U.S. Dollar as their functional currency because Ciena Corporation, as the U.S. parent entity, exclusively funds the operations of these branch offices and subsidiaries. For those subsidiaries using the local currency as their functional currency, assets and liabilities are translated at exchange rates in effect at the balance sheet date, and the statement of operations is translated at a monthly average rate. Resulting translation adjustments are recorded directly to a separate component of stockholders’ equity. Where the monetary assets and liabilities are transacted in a currency other than the entity’s functional currency, re-measurement adjustments are recorded in interest and other income (loss), net on the Consolidated Statements of Operations. See Note 6 below.

Derivatives

80

Table of Contents
From time to time, Ciena uses foreign currency forward contracts to reduce variability in certain forecasted non-U.S. Dollar denominated cash flows. Generally, these derivatives have maturities of 24 months or less. Ciena also has interest rate swap arrangements to reduce variability in certain forecasted interest expense associated with its term loans. All of these derivatives are designated as cash flow hedges. Ciena also uses foreign currency forward contracts to minimize the effect of foreign exchange rate movements on is net investments in foreign operations. Generally, these derivatives have maturities of 24 months or less. These derivatives are designated as net investment hedges. At the inception of these hedges, and on an ongoing basis, Ciena assesses whether the derivative has been effective in offsetting changes attributable to the hedged risk during the hedging period. The derivative’s net gain or loss is initially reported as a component of accumulated other comprehensive loss, and upon occurrence of the forecasted transaction, is subsequently reclassified to the line item in the Consolidated Statements of Operations to which the hedged transaction relates.

Ciena records derivative instruments in the Consolidated Statements of Cash Flows within operating, investing, or financing activities consistent with the cash flows of the hedged items.

From time to time, Ciena uses foreign currency forward contracts to hedge certain balance sheet foreign exchange exposures. These forward contracts 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 (loss), net on the Consolidated Statements of Operations.

See Notes 8 and 16 below.

Computation of Net Income per Share

Ciena calculates basic net income per common share (“Basic EPS”) by dividing earnings attributable to common stock by the weighted average number of common shares outstanding for the period. Diluted net income per potential common share (“Diluted EPS”) includes other potential dilutive shares that would be outstanding if securities or other contracts to issue common stock were exercised or converted into common stock. Ciena uses a dual presentation of Basic EPS and Diluted EPS on the face of its income statement. A reconciliation of the numerator and denominator used for the Basic EPS and Diluted EPS computations is set forth in Note 21 below.

Software Development Costs

Ciena develops software for sale to its customers. GAAP requires the capitalization of certain software development costs that are incurred subsequent to the date technological feasibility is established and prior to the date the product is generally available for sale. The capitalized cost is then amortized using the straight-line method over the estimated life of the product. Ciena defines technological feasibility as being attained at the time a working model is completed. To date, the period between Ciena achieving technological feasibility and the general availability of such software has been short, and software development costs qualifying for capitalization have been insignificant. Accordingly, Ciena has not capitalized any software development costs.

Newly Issued Accounting Standards - Not Yet 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 is effective for annual periods beginning after December 15, 2022 on a prospective basis. Early adoption is permitted. Ciena does not expect adoption of ASU 2021-08 to have a material impact on its consolidated financial statements and related disclosures.

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 on a prospective basis. Early adoption is permitted. Ciena is currently evaluating the impact of this accounting standard update on its consolidated financial statements and related disclosures.

Disaggregation of Revenue

Ciena’s disaggregated revenue as presented below depicts the nature, amount, and timing of revenue and cash flows for similar groupings of Ciena’s various offerings. The sales cycle, contractual obligations, customer requirements, and go-to-market strategies may differ for each of its product categories, resulting in different economic risk profiles for each category. Effective as of the fourth quarter of fiscal 2023, Ciena renamed its “Converged Packet Optical” product line to “Optical Networking.” This change, affecting only the presentation of such information, was made on a prospective basis and does not impact comparability of previous financial results. However, references to prior reported “Converged Packet Optical” product line have been changed herein to “Optical Networking.”

(3) CANADIAN EMERGENCY WAGE SUBSIDY

In April 2020, the Canadian government introduced the Canada Emergency Wage Subsidy (“CEWS”) to help employers offset a portion of their employee wages for a limited period in response to the COVID-19 outbreak, retroactive to March 15, 2020. The CEWS program expired in October 2021. The subsidy covered employers of all sizes and across all sectors.

Ciena accounts for proceeds from government grants as a reduction of expense when there is reasonable assurance that Ciena has met the required conditions associated with the grant and that grant proceeds will be received. Grant benefits are recorded to the particular line item of the Consolidated Statements of Operations to which the grant activity relates. Amounts from the CEWS program positively impacted Ciena’s operating expense and measures of profit in the year ended October 30, 2021. For the fiscal year ended October 30, 2021, Ciena recorded a CAD$52.2 million ($41.3 million) benefit, net of certain fees, related to CEWS for claim periods beginning March 15, 2020, including CAD$43.9 million ($35.4 million) related to employee wages during fiscal 2020.

(4) BUSINESS COMBINATIONS

Fiscal 2023 Acquisitions: Benu and Tibit
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 passive optical network (“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 Consolidated Statements of Operations.

Developed technology represents purchased technology that has reached technological feasibility and for which the acquired companies had substantially completed development as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the developed technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Developed technology is amortized on a straight-line basis over its estimated useful life of five years.
In-process technology represents purchased technology that had not reached technological feasibility as of the date of acquisition. Fair value was determined using future discounted cash flows related to the projected income stream of the in-process technology for a discrete projection period. Cash flows were discounted to their present value as of the closing date. Upon completion of the in-process technology, it will be amortized on a straight line basis over its estimated useful life, which will be determined on that date.
Customer relationships and contracts represent agreements with existing Tibit customers and have an estimated useful life of three years. Order backlog is amortized over the fulfillment period.
The goodwill generated from these acquisitions is primarily related to expected economic synergies. The total goodwill amount was recorded in the Networking Platforms segment. The goodwill is not deductible for income tax purposes.

Significant Asset Impairments

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. On March 7, 2022, Ciena announced its decision to suspend its business operations in Russia immediately. As a result, Ciena recorded impairment charges of approximately $3.8 million of which $1.8 million was a provision for credit losses.

Interest and other income (loss), net$62,008 $6,747 $(1,768)

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. During fiscal 2023 and fiscal 2022, Ciena recorded a net gain of $26.4 million and $4.1 million, respectively, on its cost method equity investments.
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 the local currency as their functional currency. During fiscal 2023 and 2021, Ciena recorded $0.4 million and $14.6 million, respectively, in exchange rate losses as a result of monetary assets and liabilities that were transacted in a currency other than the entity’s functional currency. During fiscal 2022, Ciena recorded $2.5 million in exchange rate gains as a result of monetary assets and liabilities that were transacted in a currency other than the entity’s functional currency. The related remeasurement adjustments were recorded in interest and other income (loss), net on the Consolidated Statements of Operations. From time to time, Ciena uses foreign currency forwards to hedge certain of these balance sheet exposures. These forwards are not designated as hedges for accounting purposes, and any net gain or loss associated with these derivatives is also reported in interest and other income (loss), net on the Consolidated Statements of Operations. During fiscal 2023 and 2022, Ciena recorded losses of $3.9 million and $4.0 million, respectively, from non-hedge designated foreign currency forward contracts. During fiscal 2021, Ciena recorded a gain of $11.2 million from non-hedge designated foreign currency forward contracts.

As of October 28, 2023, two customers accounted for 11.0% and 10.0% of net accounts receivable, respectively. As of October 29, 2022, two customers accounted for 13.0% and 11.0% of net accounts receivable, respectively. Ciena has not historically experienced a significant amount of bad debt expense. The following table summarizes the activity in Ciena’s allowance for credit losses for the fiscal years indicated (in thousands):

(1) On March 7, 2022, Ciena announced its decision to suspend its business operations in Russia immediately. As a result, Ciena’s allowance for doubtful accounts includes a provision for a significant asset impairment of $1.8 million for a trade receivable related to this decision.

Accounts Receivable Factoring

During fiscal 2023 and 2022, the gross amount of trade accounts receivables sold totaled approximately $60.3 million and $11.8 million, respectively. Prior to the start of fiscal 2022, Ciena had not entered into any factoring arrangements. Factoring related expense recorded to interest and other income (loss), net was $3.1 million and $0.6 million for fiscal 2023 and fiscal 2022, respectively.

(10) INVENTORIES

Inventories, net$1,050,838 $946,730 

Ciena has been expanding its manufacturing capacity and 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 when supply constraints ease for certain common components, including integrated circuit components, for which delivery continues to be delayed. Raw materials inventory is related to the steps Ciena has taken to mitigate the impact of supply chain constraints on its business and customers in recent prior periods and the global market shortage of semiconductor parts. The increase in finished goods inventories resulted primarily from planned fulfillment of customer advance orders for which some deliveries have been rescheduled outside of fiscal 2023.
Ciena makes estimates about future customer demand for its products when establishing the appropriate reserve for excess and obsolete inventory. For fiscal 2023, future demand was calculated using both customer backlog and future forecasted sales. For fiscal 2022, future demand was calculated primarily based on customer backlog. 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 fiscal 2023, fiscal 2022 and fiscal 2021, Ciena recorded a provision for excess and obsolescence of $29.5 million, $16.2 million, and $17.9 million, respectively, 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 the sale of previously reserved items and disposal activities.

(16) DERIVATIVE INSTRUMENTS

Foreign Currency Derivatives     
Ciena conducts business globally in many currencies, and thus is exposed to adverse foreign currency exchange rate changes. To limit this exposure, Ciena entered into foreign currency contracts. Ciena does not enter into such contracts for speculative purposes.    
As of October 28, 2023 and October 29, 2022, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce variability that is principally related to research and development activities. The notional amount of these contracts was approximately $367.3 million and $272.2 million as of October 28, 2023 and October 29, 2022, respectively. These foreign exchange contracts have maturities of 24 months or less and have been designated as cash flow hedges.
In May 2023, Ciena entered into 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 $48.0 million as of October 28, 2023. These foreign exchange contracts have maturities of 24 months or less and have been designated as net investment hedges.
As of October 28, 2023 and October 29, 2022, Ciena had forward contracts to hedge its foreign exchange exposure in order to reduce the variability in various currencies of certain balance sheet items. The notional amount of these contracts was approximately $226.3 million and $108.0 million as of October 28, 2023 and October 29, 2022, respectively. These foreign exchange contracts have maturities of 12 months or less and have not been designated as hedges for accounting purposes.
Interest Rate Derivatives
Ciena is exposed to floating rates of interest on its term loan borrowings (see Note 19 below) and has hedged such risk by entering into floating-to-fixed interest rate swap arrangements (“interest rate swaps”).
Prior to amending our term loan due September 28, 2025 (the “2025 Term Loan”) in January 2023, 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. In October 2018, Ciena hedged this risk by entering into interest rate swaps to fix the LIBOR rate for the first $350.0 million of its floating rate debt 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 offset the LIBOR exposure risk of the interest rate swaps and effectively fixed the SOFR rate for the first $350.0 million of its floating rate debt at 2.883% through September 2023. These swaps expired in September 2023. In April 2022, Ciena entered into forward starting interest rate swaps to fix the SOFR rate for the first $350.0 million 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 October 28, 2023.
In January 2023, Ciena entered into interest rate swaps to fix the SOFR rate 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 the 2028 interest rate swaps in effect as of October 28, 2023 was $350.0 million.
96

Table of Contents
Ciena expects the variable rate payments to be received under the terms 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 19 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 Notes 6 and 8 above.

(19) SHORT-TERM AND LONG-TERM DEBT

2030 New Term Loan

On October 24, 2023, Ciena, together with certain of its domestic subsidiaries as guarantors, entered into an Incremental Amendment Agreement (the “Amendment”) to its Credit Agreement, dated July 15, 2014, as amended (the “Credit Agreement”), by and among Ciena, certain of its subsidiaries, the lenders party thereto, and Bank of America, N.A., as administrative agent (“Bank of America”), to which Ciena incurred a new tranche of senior secured term loans in an aggregate principal amount of $1.2 billion (the “2030 New Term Loan”) and a new senior secured revolving credit facility of $300 million (the “Revolving Credit Facility” as defined in Note 20 below).

The proceeds of the 2030 New Term Loan, net of original issuance discount, replaced, in full, $668.7 million of outstanding principal of the 2025 Term Loan and $497.5 million of outstanding principal of the 2030 Term Loan (as defined below) (“Refinanced Term Loans”), including accrued interest, and pay transaction fees and expenses, resulting in proceeds of $0.8 million. The 2030 New Term Loan requires Ciena to make installment payments of $2.9 million on a quarterly basis.

Based on the continuation of existing lenders and the addition of new lenders, this arrangement was primarily accounted for as a modification of debt and, as such, $6.0 million of debt issuance costs associated with the 2030 New Term Loan were expensed. The aggregate balance of approximately $4.4 million of debt issuance costs and approximately $2.2 million of original discount from the 2025 Term Loan and 2030 Term Loan, $0.1 million of debt issuance costs associated with new lenders for the 2030 New Term Loan, and approximately $2.9 million of original discount from the 2030 New Term Loan, were included in the carrying value of the 2030 New Term Loan.

The Amendment amends the Credit Agreement and provides that the 2030 New Term Loan will, among other things:
    
mature on October 24, 2030;         
amortize in equal quarterly installments in aggregate amounts equal to 0.25% of the principal amount of the 2030 New Term Loan as of January 19, 2023, or $2.9 million, or $11.7 million annually, with the balance payable at maturity;
99

Table of Contents
be subject to mandatory prepayment upon the occurrence of certain specified events substantially similar to the Refinanced Term Loans, including upon the occurrence of certain specified events such as asset sales, debt issuances, and receipt of annual Excess Cash Flow (as defined in the Credit Agreement);

Among other things, the Amendment also amends the Credit Agreement by (i) modifying the “accordion” feature to provide for incremental term loan facilities (the “Incremental Term Loans”) in an aggregate amount not to exceed the sum of (A) the greater of (1) $640 million and (2) an amount equal to consolidated EBITDA on a pro forma basis for the most recently ended four-quarter period and (B) an amount (1) in the case of secured incremental term facilities that rank pari passu with or junior to the 2030 New Term Loan, such that the Total Secured Net Leverage Ratio (as defined in the Credit Agreement) would not be greater than 3.00 to 1.00 at the time of incurrence and (2) in the case of unsecured incremental term facilities, such that the Interest Coverage Ratio (as defined in the Credit Agreement) would not be less than 2.00 to 1.00 at the time of incurrence, subject to certain conditions, including obtaining commitments from any one or more lenders, whether or not currently party to the Credit Agreement, to provide such increased amounts and (ii) amending certain negative covenants.

(20) 循環信貸融資

2023年2月10日,根據2019年10月28日修訂的ABL信貸協議(「ABL信貸協議」),由Ciena、其某些子公司、貸方一方(「ABL貸方」)和美國銀行作爲行政代理人修改了其高級有擔保資產支持循環信貸工具(「ABL信貸融資」),其提供的總承諾爲美元300.0 百萬美元將到期日延長至2025年9月28日。

(21) 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 the effect is not anti-dilutive: (i) common shares outstanding, (ii) shares issuable upon vesting of stock unit awards; and (iii) shares issuable under Ciena’s employee stock purchase plan and upon exercise of outstanding stock options, using the treasury stock method.
The following table presents the calculation of Basic and Diluted EPS (in thousands except per share amounts):

(22) STOCKHOLDERS’ EQUITY

Stock Repurchase Program and Accelerated Share Repurchase Agreement
On December 13, 2018, Ciena announced that its Board of Directors authorized a program to repurchase up to $500 million of Ciena’s common stock. During fiscal 2021, Ciena repurchased 1.7 million shares of its common stock, for an aggregate purchase price of $92.1 million at an average price of $54.27 per share. Under this program, Ciena repurchased a total of 7.4 million shares of its common stock, for an aggregate purchase price of $316.7 million at an average price of $42.75 per share.
On December 9, 2021, Ciena announced that its Board of Directors replaced its previously authorized program, as described above, with a program to repurchase up to $1.0 billion of its common stock. On December 13, 2021, Ciena entered into an accelerated share repurchase agreement (the “ASR Agreement”) with Goldman, Sachs & Co. LLC (“Goldman”) to repurchase $250.0 million (the “Repurchase Price”) of its common stock as part of the repurchase program. Under the terms of the ASR Agreement, Ciena paid the Repurchase Price to Goldman, and received approximately 3.6 million shares of its common stock from Goldman, calculated based on the average of the volume-weighted average prices of Ciena’s common stock of $69.78 for the period from December 14, 2021 to February 11, 2022, less a discount, which completed the repurchases contemplated by the ASR Agreement. Shares repurchased pursuant to the ASR Agreement were immediately retired upon receipt. During the remainder of fiscal 2022, Ciena repurchased an additional 4.8 million shares of its common stock, for an aggregate purchase price of $250.0 million at an average price of $51.53 per share.
During fiscal 2023, Ciena repurchased an additional 5.7 million shares of its common stock, for an aggregate purchase price of $250.0 million at an average price of $44.08 per share. As of October 28, 2023, Ciena has repurchased an aggregate of 14.1 million shares for an aggregate purchase price of $750.0 million at an average price of $53.17 per share and has an aggregate of $250.0 million of authorized funds remaining under its stock repurchase program.
The purchase price for the shares of Ciena’s stock repurchased is reflected as a reduction of common stock and additional paid-in capital.

Impact of Inflation Reduction Act 1% Excise Tax on Share Repurchases

Beginning fiscal 2023, a 1% excise tax on the market value of shares repurchased offset by 1% of the market value of shares issued was implemented. During fiscal 2023, a net excise tax of $1.5 million was recorded to additional paid-in capital on the Consolidated Balance Sheets.

Stock Repurchases Related to Restricted Stock Unit Tax Withholdings
Ciena repurchases shares of common stock to satisfy employee tax withholding obligations due upon vesting of stock unit awards. The related purchase price of $38.5 million for the shares of Ciena’s stock repurchased during 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.

Our future income tax provisions and deferred tax balances may be affected by the amount of pre-tax income, the jurisdictions where it is earned, the existence and ability to utilize tax attributes and changes in tax laws and business reorganizations.

In fiscal 2021, Ciena began implementation of a plan to reorganize its global supply chain and distribution structure more substantially, which included a legal entity reorganization and related system upgrade. Ciena completed the first phase of this plan in fiscal 2021, and substantially completed the reorganization during fiscal 2022. As part of this reorganization, Ciena completed an internal transfer of certain of its non-U.S. intangible assets, which created amortizable tax basis resulting in the discrete recognition of a $119.3 million deferred tax asset with a corresponding tax benefit. The impact of this transfer is reflected in Ciena’s effective tax rate for the year ended October 30, 2021, which had a significant, one-time impact on its net income for the period.

Ciena is also required to make accounting policy elections as a result of the Tax Act. These include whether a valuation allowance is recorded for the estimated effect of the application of GILTI and BEAT or if these will be treated as period costs when incurred. Ciena had made the incremental cash tax cost policy election with respect to analyzing the impact of GILTI on the assessment of the realizability of net operating losses. The realizability of U.S. tax carryforwards is not impacted by the BEAT, and the BEAT is a period cost when incurred. Ciena is also required to elect to treat taxes due on future GILTI inclusions in U.S. taxable income either as a current period expense when incurred or reflect such portion of the future GILTI inclusions in U.S. taxable income that relate to existing basis differences in Ciena’s current measurement of deferred taxes. Ciena’s accounting policy election is to treat the taxes due on future U.S. inclusions in taxable income under GILTI as a period cost when incurred.

As of October 28, 2023 and October 29, 2022, Ciena had accrued $7.9 million and $5.2 million of interest and penalties, respectively, related to unrecognized tax benefits included in other long-term obligations in the Consolidated Balance Sheets. Interest and penalties of $2.7 million and $1.7 million were recorded as a net expense to the provision for income taxes during fiscal 2023 and 2022, respectively. During fiscal 2021, Ciena recorded a net benefit to the provision for interest and penalties in its provision for income taxes of $0.1 million. If recognized, the entire balance of unrecognized tax benefits would impact the effective tax rate. Over the next 12 months, Ciena does not estimate any material changes in unrecognized income tax benefits.

During the fourth quarter of fiscal 2023, Ciena evaluated the undistributed earnings of its foreign subsidiaries and identified approximately $222.0 million in earnings that are no longer considered to be indefinitely reinvested. Ciena recorded a provision of $2.5 million that reflects the income tax effects of the repatriation of these earnings. No additional income tax expense has been provided for any remaining undistributed foreign earnings, or any additional outside basis difference from investments in the foreign subsidiaries, as these amounts continue to be indefinitely reinvested. If the remaining undistributed foreign earnings and profits of $381.0 million were repatriated to the U.S., the provisional amount of unrecognized deferred tax liability, which is primarily related to foreign withholding taxes, is an estimated $30.0 million; however, the amount may be lower depending on Ciena’s ability to utilize tax credits associated with the distribution. Additionally, there are no other significant temporary differences for which a deferred tax liability or asset has not been recognized.

As of October 28, 2023, Ciena continues to maintain a valuation allowance of $189.9 million against its gross deferred tax assets primarily. The valuation allowance is primarily related to state and foreign net operating losses and credits that Ciena estimates it will not be able to use.

The following table summarizes the activity in Ciena’s valuation allowance against its gross deferred tax assets (in thousands):

(24) SHARE-BASED COMPENSATION EXPENSE

Ciena has outstanding equity awards issued under its 2017 Omnibus Incentive Plan (the “2017 Plan”), its 2008 Omnibus Incentive Plan, and certain legacy equity plans and equity plans assumed as a result of previous acquisitions. All equity awards granted on or after March 23, 2017 are made exclusively from the 2017 Plan. Ciena also makes shares of its common stock available for purchase under the ESPP. Each of the 2017 Plan and the ESPP are described below.
106

Table of Contents

2017 Plan

The 2017 Plan has a ten-year term and authorizes the issuance of awards including stock options, restricted stock units (RSUs), restricted stock, unrestricted stock, stock appreciation rights (SARs) and other equity and/or cash performance incentive awards to employees, directors and consultants of Ciena. Subject to certain restrictions, the Compensation Committee of the Board of Directors has broad discretion to establish the terms and conditions for awards under the 2017 Plan, including the number of shares, vesting conditions, and the required service or performance criteria. Options and SARs have a maximum term of ten years, and their exercise price may not be less than 100% of fair market value on the date of grant. Repricing of stock options and SARs is prohibited without stockholder approval. Certain change in control transactions may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the transaction.

The 2017 Plan authorizes and reserves 21.1 million shares for issuance. The number of shares available under the 2017 Plan are also increased from time to time by: (i) the number of shares subject to outstanding awards granted under Ciena’s prior equity compensation plans that are forfeited, expire or are canceled without delivery of common stock following the effective date of the 2017 Plan, and (ii) the number of shares subject to awards assumed or substituted in connection with the acquisition of another company. As of October 28, 2023, the total number of shares authorized for issuance under the 2017 Plan was 21.1 million and approximately 5.6 million shares remained available for issuance thereunder.

Stock Options

There were no stock options granted by Ciena during fiscal 2023, fiscal 2022 or fiscal 2021. Outstanding stock option awards granted to employees in prior periods are generally subject to service-based vesting conditions and vest over a four-year period.

Assumptions for Option-Based Awards

Ciena recognizes the fair value of stock options as share-based compensation expense on a straight-line basis over the requisite service period. Ciena did not grant any option-based awards during fiscal 2023, fiscal 2022 or fiscal 2021.

Restricted Stock Units
A restricted stock unit is a stock award that entitles the holder to receive shares of Ciena common stock as the unit vests. Ciena’s outstanding restricted stock unit awards are subject to service-based vesting conditions and/or performance-based vesting conditions. Awards subject to service-based conditions typically vest in increments over a three or four-year period.
107

Table of Contents
However, the 2017 Plan permits Ciena to grant service-based stock awards with a minimum one-year vesting period. Awards with performance-based vesting conditions (i) require the achievement of certain operational, financial or other performance criteria or targets or (ii) vest based on Ciena’s total stockholder return as compared to an index of peer companies, in whole or in part.
During fiscal 2023, Ciena introduced a benefit pursuant to 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.

Assumptions for Restricted Stock Unit Awards

Ciena recognizes the estimated fair value of restricted stock units subject only to service-based vesting conditions by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Share-based expense for service-based restricted stock unit awards is recognized ratably over the vesting period on a straight-line basis.

Ciena recognizes the estimated fair value of restricted stock units subject to performance-based vesting conditions other than total stockholder return, by assuming the satisfaction of any performance-based objectives at the “target” level and multiplying the corresponding number of shares earned based upon such achievement by the closing price per share of Ciena common stock on the grant date. Share-based compensation expense is recognized over the performance period, using graded vesting, which considers each performance period or tranche separately, based on Ciena’s determination of whether it is probable that the performance targets will be achieved. At the end of each reporting period, Ciena reassesses the probability of achieving the performance targets and the performance period required to meet those targets. The estimation of whether the performance targets will be achieved involves judgment. Revisions are reflected in the period in which the estimate is changed. If any performance goals are not met, no compensation cost is ultimately recognized against that goal and, to the extent previously recognized, compensation expense is reversed.

Share-based compensation expense for restricted stock units subject only to service-based vesting conditions and restricted stock units subject to performance-based vesting conditions other than total stockholder return, is recognized only for those awards that ultimately vest. In the event of a forfeiture of an award, the expense related to the unvested portion of that award is reversed. Reversal of share-based compensation expense based on forfeitures can materially affect the measurement of estimated fair value of Ciena’s share-based compensation.

Ciena recognizes the estimated fair value of performance based awards subject to total stockholder return as compared to an index of peer companies using a Monte Carlo simulation valuation model. Ciena reverses share-based compensation expense on performance based awards subject to total shareholder return only when the requisite service period is not reached. Assumptions for awards granted during fiscal 2023, fiscal 2022 and fiscal 2021 included the following:

As of October 28, 2023 and October 29, 2022, 0.3 million of the total restricted stock units outstanding are performance based awards subject to total stockholder return. The total fair value of restricted stock units that vested and were converted into common stock during fiscal 2023, fiscal 2022 and fiscal 2021 was $98.2 million, $119.0 million and $110.0 million, respectively. The weighted average fair value of each restricted stock unit granted by Ciena during fiscal 2023, fiscal 2022 and fiscal 2021 was $50.48, $67.03 and $48.70, respectively.

Amended and Restated ESPP
Ciena makes shares of its common stock available for purchase under the ESPP, under which eligible employees may enroll in a twelve-month offer period that begins in December and June of each year. Each offer period includes two six-month purchase periods. Employees may purchase a limited number of shares of Ciena common stock at 85% of the fair market value on either the day immediately preceding the offer date or the purchase date, whichever is lower. The ESPP is considered compensatory for purposes of share-based compensation expense. Unless earlier terminated, the ESPP will terminate on April 1, 2031.
During fiscal 2023, Ciena issued 0.8 million shares and during both fiscal 2022 and fiscal 2021, Ciena issued 0.7 million shares, respectively, under the ESPP. At October 28, 2023, 11.3 million shares remained available for issuance under the ESPP.

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 Exchange Act). Based on 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.
Report of Management on Internal Control Over Financial Reporting
The management of Ciena Corporation is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).
The internal control over financial reporting at Ciena Corporation was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes those policies and procedures that:
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of Ciena Corporation;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with accounting principles generally accepted in the United States of America;
provide reasonable assurance that receipts and expenditures of Ciena Corporation are being made only in accordance with authorization of management and directors of Ciena Corporation; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of assets that could have a material effect on the consolidated financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.
Management of Ciena Corporation assessed the effectiveness of the Company’s internal control over financial reporting as of October 28, 2023. Management based this assessment on criteria for effective internal control over financial reporting described in “COSO 2013 Internal Control — Integrated Framework” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management determined that, as of October 28, 2023, Ciena Corporation maintained effective internal control over financial reporting. Management reviewed the results of its assessment with the Audit Committee of our Board of Directors.
PricewaterhouseCoopers LLP, independent registered public accounting firm, who audited and reported on the consolidated financial statements of Ciena Corporation included in this annual report, has also audited the effectiveness of Ciena Corporation’s internal control over financial reporting as of October 28, 2023, as stated in its report appearing in Item 8 of Part II of this annual report.
