Notes to Investors:
Forward-Looking Statements. You are encouraged to review the Investors section of our website, where we routinely post press releases, Securities and Exchange Commission (“SEC”) filings, recent news, financial results, supplemental financial information, and other announcements. 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.
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.”
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.
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
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.
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.
About Ciena. Ciena (NYSE: CIEN) is the global leader in high-speed connectivity. We build the world’s most adaptive networks to support exponential growth in bandwidth demand. By harnessing the power of our networking systems, interconnects, automation software, and services, Ciena revolutionizes data transmission and network management.

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