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.

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.
•Canadian Emergency Wage Subsidy - a program introduced by the Government of Canada to offset a portion of employee wages for a limited period in response to COVID-19 outbreak.
•Significant asset impairments and restructuring costs - costs incurred as a result of restructuring activities taken to align resources with perceived market opportunities 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 its expected useful life.
•Acquisition and integration costs - includes expenses for financial, legal and accounting advisors, severance and other employee-related costs associated with our acquisition of Centina in fiscal 2020, and costs and recoveries of acquisition consideration and compensation associated with a three-year earn-out arrangement related to the DonRiver acquisition in fiscal 2018. Ciena does not believe that these costs are reflective of its ongoing operating expense following its completion of these integration activities.
•Loss on extinguishment and modification of debt - reflects extinguishment and modification of debt expenses related to refinancing of our Term Loan due September 28, 2025.
•Unrealized (gain)loss on equity investment - reflects a change in the carrying value of certain cost method equity investments.
•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 20.5% for fiscal 2021 and 21.6% for fiscal 2020. This rate may be subject to change in the future, including as a result of changes in tax policy or tax strategy.
Ciena's GAAP tax provision for fiscal 2021 benefited from recording a $119.3 million tax benefit related to an
internal transfer of non-U.S. intangible assets that was recognized as a result of the step-up in basis of such
rights for tax purposes. The Non-GAAP tax provision for the periods presented do not include this tax benefit or
the corresponding deferred tax asset.
