Share Repurchases: Repurchased approximately 154,200 shares of common stock for an aggregate price of $8.0 million during the quarter.

“Our strong fiscal fourth quarter financial results were better than expected as we benefited from some favorable supply chain developments in the second half of the quarter,” said Gary Smith, president and CEO of Ciena. “Looking ahead, we expect to deliver outsized revenue growth in fiscal 2023 given our significant backlog and continued signs of gradual supply improvement. And, we remain confident that the durability of secular demand drivers and our strategic investments to expand our addressable market position us to deliver strong revenue growth over the next several years.”

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: “Our strong fiscal fourth quarter financial results were better than expected as we benefited from some favorable supply chain developments in the second half of the quarter,” said Gary Smith, president and CEO of Ciena. “Looking ahead, we expect to deliver outsized revenue growth in fiscal 2023 given our significant backlog and continued signs of gradual supply improvement. And, we remain confident that the durability of secular demand drivers and our strategic investments to expand our addressable market position us to deliver strong revenue growth over the next several years.”

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 customers and their business; our ability to execute our business and growth strategies; the impact of supply chain constraints or disruptions; the duration and severity of the COVID-19 pandemic and the impact of countermeasures taken to mitigate its spread on macroeconomic conditions, economic activity, demand for our technology solutions, short- and long-term changes in customer or end user needs, continuity of supply chain, our business operations, liquidity and financial results; changes in network spending or network strategy by our customers; seasonality and the timing and size of customer orders, including 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 events, including but not limited to the ongoing conflict between Ukraine and Russia, and public health emergencies; changes in tax or trade regulations, including the imposition of tariffs, duties or efforts to withdraw from or materially modify international trade agreements; and the other risk factors disclosed in Ciena’s periodic reports filed with the Securities and Exchange Commission (SEC) including its Quarterly Report on Form 10-Q filed with the SEC on September 7, 2022 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.

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, the redesign of business processes and, in fiscal 2022, a $3.8 million impairment charge due to Ciena’s decision to suspend its business operations in Russia in response to the conflict in Ukraine.

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 financial, legal and accounting advisor expenses related to our acquisition activity in fiscal 2022. Acquisition and integration costs for fiscal 2021 include costs of acquisition compensation associated with a three-year earn-out arrangement related to the DonRiver acquisition in fiscal 2018.

Unrealized (gain)loss on cost method equity investment – reflects a change in the carrying value of a certain cost method equity investment.

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 20.2% for fiscal quarter 2022 and 20.5% for fiscal quarter 2021. This rate may be subject to change in the future, including as a result of changes in tax policy or tax strategy.
