From time to time we exclusively post material information to this website along with other disclosure channels that we use. This press release contains certain forward-looking statements that involve risks and uncertainties. These statements are based on current expectations, forecasts, assumptions and other information available to the Company as of the date hereof. Forward-looking statements include statements regarding Ciena's expectations, beliefs, intentions or strategies regarding the future and can be identified by forward-looking words such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "should," "will," and "would" or similar words. Forward-looking statements in this release include the statements in the "Summary" and "Business Outlook" sections of this press release and "Our record fiscal fourth quarter and full-year performance underscores our focused execution and solidifies our position as a global leader in high-speed connectivity with an expanding role in the evolving AI ecosystem.

前瞻性聲明。 我們鼓勵您查看我們網站的投資者部分，我們定期發佈新聞稿、證券交易委員會（"SEC"）文件、最新消息、財務結果、補充財務信息和其他公告。我們不時會將重要信息獨家發佈到該網站以及我們使用的其他披露渠道。本新聞稿包含某些前瞻性聲明，這些聲明涉及風險和不確定性。這些聲明基於截至本日期公司當前的期望、預測、假設和其他信息。前瞻性聲明包括關於 Ciena 的期望、信念、意圖或未來戰略的聲明，並可以通過諸如 “預期”、“相信”、“可能”、“估計”、“期望”、“打算”、“可能”、“應該”、“將” 和 “會” 或類似詞彙來識別。本聲明中的前瞻性聲明包括本新聞稿 “摘要” 和 “商業展望” 部分的聲明，以及 “我們創紀錄的財年第四季度和全年業績強調了我們的專注執行，並鞏固了我們作為高速連接全球領導者的地位，同時在不斷發展的 AI 生態系統中扮演着日益重要的角色。

Looking ahead, we are increasingly confident in our growth trajectory over the coming years, driven by accelerating, durable demand from our cloud and service provider customers and a growing set of opportunities inside and around the data center." and “With our growing operating leverage, and strong cash generation and balance sheet, we are well-positioned to deliver value for our customers and shareholders in 2026."

展望未來，我們對未來幾年的增長軌跡越來越有信心，這得益於來自雲服務提供商客户的加速、持久的需求，以及數據中心內外日益增長的機會。“憑藉我們不斷增長的運營槓桿、強勁的現金生成和資產負債表，我們在 2026 年為客户和股東創造價值的能力良好。”

Ciena's actual results, performance or events may differ materially from these forward-looking statements made or implied due to a number of risks and uncertainties relating to Ciena's business, including: the effect of broader economic and market conditions on our business and that of our customers, including their spending; the development and use of artificial intelligence and its impact on overall networking technology spending; our ability to execute our business and growth strategies; supply chain constraints or disruptions including increased costs and lead times; the introduction of new technologies by us or our competitors; the timing and size of customer orders, their delivery dates and our ability to recognize revenue relating to such sales; the level of competitive pressure we encounter; the product, customer and geographic mix of sales within the period; changes in foreign currency exchange rates; factors beyond our control such as natural disasters, climate change, acts of war or terrorism, geopolitical tensions or events, and public health emergencies, epidemics, or pandemics; changes in tax or trade regulations, including the imposition of tariffs, duties or efforts to withdraw from or materially modify international trade agreements; cyberattacks, data breaches or other security incidents involving our enterprise network environment or our products; regulatory changes, litigation involving our intellectual property or government investigations; and the other risk factors disclosed in Ciena’s periodic reports filed with the Securities and Exchange Commission (SEC) including Ciena's Quarterly Report on Form 10-Q filed with the SEC on September 4, 2025 and its Annual Report on Form 10-K to be filed with the SEC. Ciena assumes no obligation to update any forward-looking information included in this press release.

Ciena 的實際結果、表現或事件可能因與 Ciena 業務相關的多種風險和不確定性而與這些前瞻性聲明存在重大差異，包括：更廣泛的經濟和市場條件對我們及客户業務的影響，包括他們的支出；人工智能的發展和使用及其對整體網絡技術支出的影響；我們執行業務和增長戰略的能力；供應鏈限制或中斷，包括成本和交貨時間的增加；我們或競爭對手推出新技術的時機和規模；客户訂單的時機和規模、交貨日期及我們確認與此類銷售相關的收入的能力；我們面臨的競爭壓力水平；銷售的產品、客户和地理組合；外匯匯率的變化；超出我們控制範圍的因素，如自然災害、氣候變化、戰爭或恐怖主義行為、地緣政治緊張局勢或事件，以及公共衞生緊急情況、流行病或大流行；税收或貿易法規的變化，包括關税、税收或撤回或實質性修改國際貿易協議的努力；網絡攻擊、數據泄露或涉及我們企業網絡環境或產品的其他安全事件；監管變化、涉及我們知識產權的訴訟或政府調查；以及在 Ciena 向證券交易委員會（SEC）提交的定期報告中披露的其他風險因素，包括 Ciena 於2025年9月4日向 SEC 提交的 10-Q 季度報告和即將向 SEC 提交的 10-K 年度報告。Ciena 不承擔更新本新聞稿中包含的任何前瞻性信息的義務。

Non-GAAP Presentation of Quarterly and Annual Results. This release includes non-GAAP measures of Ciena's gross profit, operating expense, income from operations, earnings before interest, tax, depreciation and amortization (EBITDA), Adjusted EBITDA, and measures of net income and net income per share. In evaluating the operating performance of Ciena's business, management excludes certain charges and credits that are required by GAAP. These items share one or more of the following characteristics: they are unusual and Ciena does not expect them to recur in the ordinary course of its business; they do not involve the expenditure of cash; they are unrelated to the ongoing operation of the business in the ordinary course; or their magnitude and timing is largely outside of Ciena's control. Management believes that the non-GAAP measures below provide management and investors useful information and meaningful insight to the operating performance of the business. The presentation of these

非公認會計原則季度和年度業績的呈現。本發佈包含了 Ciena 的非公認會計原則的毛利潤、運營費用、營業收入、息税折舊攤銷前利潤（EBITDA）、調整後的 EBITDA，以及淨收入和每股淨收入的指標。在評估 Ciena 業務的運營表現時，管理層排除了根據公認會計原則（GAAP）要求的某些費用和收入。這些項目具有以下一個或多個特徵：它們是異常的，Ciena 不期望它們在正常業務過程中再次發生；它們不涉及現金支出；它們與正常業務的持續運營無關；或者它們的規模和時機在很大程度上超出了 Ciena 的控制範圍。管理層認為，以下非公認會計原則的指標為管理層和投資者提供了有用的信息和對業務運營表現的有意義的洞察。

non-GAAP financial measures should be considered in addition to Ciena's GAAP results and these measures are not intended to be a substitute for the financial information prepared and presented in accordance with GAAP. Ciena's non-GAAP measures and the related adjustments may differ from non-GAAP measures used by other companies and should only be used to evaluate Ciena's results of operations in conjunction with our corresponding GAAP results. To the extent not previously disclosed in a prior Ciena financial results press release, Appendices A and B to this press release set forth a complete GAAP to non-GAAP reconciliation of the non-GAAP measures contained in this release.

非公認會計原則的財務指標應與 Ciena 的 GAAP 結果一起考慮，這些指標並不打算替代根據 GAAP 編制和呈現的財務信息。Ciena 的非公認會計原則指標及相關調整可能與其他公司使用的非公認會計原則指標不同，僅應與我們的相應 GAAP 結果一起用於評估 Ciena 的運營結果。在之前的 Ciena 財務結果新聞稿中未披露的情況下，本新聞稿的附錄 A 和 B 列出了本發佈中包含的非公認會計原則指標的完整 GAAP 與非 GAAP 的對賬。

With respect to Ciena’s expectations under “Business Outlook" above, Ciena is not able to provide a quantitative reconciliation of the adjusted (non-GAAP) gross margin and adjusted (non-GAAP) operating expense guidance measures to the corresponding gross profit and gross profit percentage, and operating expense GAAP measures without unreasonable efforts. Ciena cannot provide meaningful estimates of the non-recurring charges and credits excluded from these non-GAAP measures due to the forward-looking nature of these estimates and their inherent variability and uncertainty. For the same reasons, Ciena is unable to address the probable significance of the unavailable information.

關於 Ciena 在 “商業展望” 中的預期，Ciena 無法提供調整後的（非 GAAP）毛利率和調整後的（非 GAAP）運營費用指導指標與相應的毛利潤和毛利率、以及 GAAP 運營費用指標之間的定量對賬，除非付出不合理的努力。由於這些估計的前瞻性特性及其固有的變動性和不確定性，Ciena 無法提供被排除在這些非公認會計原則指標之外的非經常性費用和收入的有意義估計。出於同樣的原因，Ciena 無法説明不可用信息的可能重要性。

The adjusted (non-GAAP) measures above and their reconciliation to Ciena's GAAP results for the periods presented reflect adjustments relating to the following items:

上述調整後的（非 GAAP）指標及其與 Ciena GAAP 結果的對比反映了與以下項目相關的調整：

Share-based compensation - a non-cash expense incurred in accordance with share-based compensation accounting guidance.

基於股份的補償 - 根據基於股份的補償會計指導產生的非現金費用。

Significant asset impairments and restructuring costs - non-recurring costs primarily reflecting expenses associated with significant impairment or abandonment of assets and actions Ciena has taken to restructure our business, including reductions in force, facility optimization, and the redesign of business processes. For the fiscal fourth quarter and fiscal year of 2025, this also includes a charge of $89.1 million related to the abandonment of an in-process R&D intangible asset.

重大資產減值和重組費用 - 非經常性費用，主要反映與重大資產減值或放棄資產相關的費用，以及 Ciena 為重組業務所採取的措施，包括裁員、設施優化和業務流程重新設計。對於 2025 財年的第四季度和全年，這還包括與放棄一個正在進行的研發無形資產相關的 8900 萬美元的費用。

Amortization of intangible assets - a non-cash expense arising from the acquisition of intangible assets, principally developed technologies and customer-related intangibles, that Ciena is required to amortize over an expected useful life. Acquisition and integration costs - consists of financial, legal, and accounting advisors and employee-related costs related to our acquisition of Nubis Communications, Inc. during the fourth quarter of fiscal 2025.

無形資產攤銷 - 由於收購無形資產（主要是開發技術和與客户相關的無形資產）而產生的非現金費用，Ciena 需要在預期的使用壽命內進行攤銷。收購和整合成本 - 包括與我們在 2025 財年第四季度收購 Nubis Communications, Inc.相關的財務、法律和會計顧問費用以及員工相關費用。

Holdback arrangement - reflects a one-time holdback of a portion of the merger consideration otherwise payable at closing to certain key employee shareholders of Nubis Communications, Inc. who became employees of Ciena, which is treated as contingent compensation for GAAP reporting purposes. These transaction-related amounts are not part of Ciena's standard compensation and benefits.

保留安排 - 反映了對 Nubis Communications, Inc.的某些關鍵員工股東在交易完成時應支付的合併對價的一次性保留，這些股東成為了 Ciena 的員工，該保留被視為 GAAP 報告目的下的或有補償。這些與交易相關的金額不屬於 Ciena 的標準薪酬和福利。

Loss on extinguishment and modification of debt - reflects extinguishment and debt modification expenses related to refinancing our term loan during the first quarter of fiscal 2025.

債務的解除和修改損失 - 反映了與我們在 2025 財年第一季度重新融資定期貸款相關的解除和債務修改費用。

Non-GAAP tax provision - consists of current and deferred income tax expense commensurate with the level of adjusted income before income taxes and utilizes a current, blended U.S. and foreign statutory annual tax rate of 22.0% for all fiscal periods of fiscal 2025 and fiscal 2024. This rate may be subject to change in the future, including as a result of changes in tax policy or tax strategy. The Non-GAAP tax provision excludes the impact of a $21.6 million tax benefit in the fourth quarter of fiscal 2025 related to the expiration of the statute of limitations on previously uncertain tax positions.

非 GAAP 税務準備金 - 包括與調整後的税前收入水平相稱的當前和遞延所得税費用，並對 2025 財年和 2024 財年的所有財務期間採用 22.0% 的當前混合美國和外國法定年税率。該税率可能會因未來税收政策或税收戰略的變化而有所調整。非 GAAP 税務準備金不包括與 2025 財年第四季度相關的 2160 萬美元税收利益的影響，該利益與之前不確定税務立場的時效期限到期有關。
