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 "Business Outlook" section of this press release and "We delivered a very strong fiscal first quarter, driven by focused execution and unprecedented, broad-based demand as we enable customers to monetize their AI investments. With industry‑leading technology and deep customer relationships, we are well positioned to meet multi‑year demand as AI‑driven networking continues to scale. We are investing and executing to deliver long‑term value for our shareholders and to support the full range of our customers' high‑speed connectivity needs." and "With a historically strong order book and record Q1 backlog, we are poised to deliver strong results, supported by durable demand, through 2026 and into 2027. Our strong balance sheet and financial discipline position the company to meet growing demand while improving profitability and shareholder returns."

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 fulfill and 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 its Annual Report on Form 10-K filed with the SEC on December 12, 2025 and included in its Quarterly Report on Form 10-Q for the first quarter of fiscal 2026 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, adjusted (non-GAAP) operating expense, and adjusted (non-GAAP) operating margin guidance measures to the corresponding gross margin, operating expense, and operating margin 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.

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 actions Ciena has taken to restructure our business, including reductions in force, facility optimization, and the redesign of business processes.
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 20% for the first quarter of fiscal 2026 and 22% for the first quarter of fiscal 2025. This rate may be subject to change in the future, including as a result of changes in tax policy or tax strategy.
