HANOVER, Md. - September 1, 2016 - Ciena® Corporation (NYSE: CIEN), the network specialist, today announced unaudited financial results for its fiscal third quarter ended July 31, 2016.

For the fiscal third quarter 2016, Ciena reported revenue of $670.6 million as compared to $602.9 million for the fiscal third quarter 2015.

Ciena's adjusted (non-GAAP) net income for the fiscal third quarter 2016 was $67.6 million, or $0.42 per diluted common share, which compares to an adjusted (non-GAAP) net income of $50.7 million, or $0.37 per diluted common share, for the fiscal third quarter 2015.

Notes to Investors

Forward-Looking Statements. You are encouraged to review the Investors section of our website, where we routinely post press releases, 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: “We posted strong results on all financial operating metrics in our fiscal third quarter, continuing a trend of consistently improving financial performance and demonstrating the value of having a diversified business to manage through market dynamics."; "Through strategic investments to broaden our portfolio, market application and customer and geographic base, we have positioned Ciena to deliver sustainable long-term growth and increased profitability."; "Ciena expects fiscal fourth quarter 2016 financial performance to include: Revenue in the range of $700 to $730 million; Adjusted (non-GAAP) gross margin in the mid-40s percentage range; Adjusted (non-GAAP) operating expense of approximately $230 to $235 million."

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; changes in network spending or network strategy by large communication service providers; 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; supply chain disruptions and the level of success relating to efforts to optimize Ciena's operations; changes in foreign currency exchange rates affecting revenue and operating expense; and the other risk factors disclosed in Ciena's Report on Form 10-Q, which Ciena filed with the Securities and Exchange Commission on June 8, 2016. Ciena assumes no obligation to update any forward-looking information included in this press release.

Non-GAAP Presentation of Quarterly Results. This release includes non-GAAP measures of Ciena's gross profit, operating expense, income (loss) from operations, net income (loss) and net income (loss) 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, Appendix A to this press release sets 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 for Fiscal Fourth Quarter 2016” 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.

Weighted average dilutive potential common shares outstanding used in calculating Adjusted (non-GAAP) diluted net income per common share for the third quarter of fiscal 2016 includes 0.9 million shares underlying certain stock options and restricted stock units, 12.2 million shares underlying Ciena's 0.875% convertible senior notes, due June 15, 2017, 17.4 million shares underlying Ciena's 3.75% convertible senior notes, due October 15, 2018 and 9.2 million shares underlying Ciena's 4.0% convertible senior notes, due December 15, 2020.
Weighted average dilutive potential common shares outstanding used in calculating Adjusted (non-GAAP) diluted net income per common share for the third quarter of fiscal 2015 includes 1.7 million shares underlying certain stock options and restricted stock units, 13.1 million shares underlying Ciena's 0.875% convertible senior notes, due June 15, 2017, 17.4 million shares underlying Ciena's 3.75% convertible senior notes, due October 15, 2018 and 9.2 million shares underlying Ciena's 4.0% convertible senior notes, due December 15, 2020.
2.
The calculation of Adjusted (non-GAAP) diluted net income per common share for the third quarter of fiscal 2016 requires adding back interest expense of approximately $1.3 million associated with Ciena's 0.875% convertible senior notes, due June 15, 2017, approximately $3.6 million associated with Ciena's 3.75% convertible senior notes, due October 15, 2018 and approximately $2.9 million associated with Ciena's 4.0% convertible senior notes, due December 15, 2020 to the Adjusted (non-GAAP) net income in order to derive the numerator for the Adjusted earnings per common share calculation.
The calculation of Adjusted (non-GAAP) diluted net income per common share for the third quarter of fiscal 2015 requires adding back interest expense of approximately $1.4 million associated with Ciena's 0.875% convertible senior notes, due June 15, 2017, approximately $3.6 million associated with Ciena's 3.75% convertible senior notes, due October 15, 2018 and approximately $2.8 million associated with Ciena's 4.0% convertible senior notes, due December 15, 2020 to the Adjusted (non-GAAP) net income in order to derive the numerator for the Adjusted earnings per common share calculation.

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.
Acquisition and integration costs - consist of expenses for financial, legal and accounting advisors and severance and other employee related costs, associated with our acquisition of Cyan, Inc. on August 3, 2015 and our acquisition of certain high-speed photonic component assets from TeraXion, Inc. on February 1, 2016. Ciena does not believe that these costs are reflective of its ongoing operating expense following its completion of these integration activities.
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.
Restructuring costs - costs incurred as a result of restructuring activities taken to align resources with perceived market opportunities.
Settlement of patent litigation - included in general and administrative expense is a $0.5 million patent litigation settlement during the third quarter of fiscal 2015.
Gain on extinguishment of debt - a gain related to certain private repurchases conducted with several holders of Ciena's 0.875% convertible senior notes, due June 15, 2017.
Non-cash interest expense - a non-cash debt discount expense amortized as interest expense during the term of Ciena's 4.0% senior convertible notes due December 15, 2020 relating to the required separate accounting of the equity component of these convertible notes.
