    Election of Class III Directors and Class II Director Overview Our Board of Directors currently consists of ten directors divided into three classes. Each class of our Board of Directors serves a three-year term, and the terms of each class are staggered. At the Annual Meeting, four directors will be elected to fill positions in Class III. Hassan M. Ahmed, Ph.D., Bruce L. Claflin, Patrick T. Gallagher, and T. Michael Nevens, each of whom is a current Class III director whose current term expires at the Annual Meeting, are nominees for election at the Annual Meeting. Each of the nominees for Class III, if elected, will serve for a three-year term expiring at the 2027 Annual Meeting, or until such director’s successor is duly elected and qualified, or until such director’s earlier death, resignation, or removal from the Board. Effective August 30, 2023, the Board of Directors increased the size of the Board from nine to ten directors and appointed Mary G. Puma to fill the newly created vacancy in Class II of the Board. Ms. Puma was initially identified as a possible candidate for Board service as part of a review of the external networks of members of our Board of Directors, and a vetting process involving management, the Board, and a third-party search firm engaged by the Board was conducted prior to her recommendation. The term of office for Class II directors continues until the 2026 Annual Meeting, or until their successors are duly elected and qualified. Our bylaws, however, limit the term of office of any director appointed by the Board of Directors to fill a vacancy to a term that lasts until the first annual meeting following appointment. Ms. Puma is therefore a nominee for election at the Annual Meeting. Our bylaws also provide that any director so elected will serve the remainder of the term of the class to which such director was elected. Accordingly, if elected by stockholders at the Annual Meeting, Ms. Puma will serve the remainder of her term as a Class II director until the 2026 Annual Meeting, or until her successor is duly elected and qualified, or until her earlier death, resignation, or removal from the Board. The nomination of these directors to stand for election at the Annual Meeting has been recommended by the Governance and Nominations Committee and approved by the Board of Directors. Director qualifications The Governance and Nominations Committee reviews candidates for service on the Board of Directors and recommends nominees for election to fill vacancies on the Board, including nomination for re-election of directors whose terms are due to expire. The Governance and Nominations Committee endeavors to identify, recruit and nominate candidates who possess a combination of wisdom, sound judgment, excellent business skills, maturity, and high integrity. In particular, the Governance and Nominations Committee seeks individuals with a record of accomplishment and senior leadership experience in their chosen fields who display the independence of mind and strength of character to be committed to representing the long-term interests of various stakeholders, including our stockholders, customers, partners, employees and community. The Governance and Nominations Committee also seeks to ensure that the Board of Directors is composed of individuals of diverse backgrounds, including with respect to gender, ethnicity, race, nationality and age, who have a variety of complementary experience, skills and relationships relevant to Ciena’s business and industry. The Governance and Nominations Committee also sees the benefit of diversity in terms of tenure and having a mix of individuals with a diverse range of experience as a director, whether on Ciena’s Board or that of another company. This diversity of background and experience includes ensuring that the Board includes individuals with experience or skills sufficient to meet the requirements of the various rules and regulations of The New York Stock Exchange (the “NYSE”) and the SEC, such as the requirements to have a majority of independent directors, committees composed only of independent directors, and an audit committee financial expert. As required by the Governance and Nominations Committee Charter, the committee has developed and uses criteria for maintaining a balanced board of directors that possess a diversity of characteristics and recommends criteria, establishes procedures for, and conducts an annual review of the Board and the diversity and other characteristics of individual directors and reports to the Board on the results of the review. In nominating candidates to fill vacancies created by the expiration of the term of a director, the Governance and Nominations Committee determines whether the incumbent director is willing to stand for re-election. If so, the Governance and Nominations Committee evaluates the director’s performance to determine suitability for continued service, taking into consideration, among other things, the director’s contributions to the Board, the value of the continuity of the director’s service, and the director’s familiarity with Ciena’s markets, business and operations.

    Independence and diversity The above charts reflect information for our nominees and continuing directors. Annually, we ask each of our nominees and continuing directors to self-identify based on both their skills and experience and a range of diversity characteristics, including gender, race, ethnicity, sexual orientation, and disability. In response, three of our nominees and continuing directors self-identified as female and two self-identified as Asian or South Asian, one of whom self-identified as an Indian American from Malaysia. Each of the nominees has consented to serve if elected. However, if any of the persons nominated by the Board of Directors fails to stand for election, or declines to accept election, or is otherwise unavailable for election prior to our Annual Meeting, proxies solicited by our Board of Directors will be voted by the proxy holders for the election of any other person or persons as the Board of Directors may recommend, or our Board of Directors, at its option, may reduce the number of directors that constitute the entire Board of Directors.

  50. Equity compensation

    Equity compensation Our equity compensation program for our non-employee directors and Dr. Nettles for fiscal 2023 was as follows:

  51. Equity compensation

    | Equity Compensation | Target Delivered Value ($) | | Initial RSU Award — Upon Director Election or Appointment | $225,000 | | Annual RSU Award — Non-Employee Directors and Executive Chair | $225,000 |

  52. Equity compensation

    In order to control for possible volatility in our stock price on any one particular trading day, the actual number of shares underlying restricted stock unit (“RSU”) awards granted to directors is determined based on the average closing price of Ciena’s common stock over the 30-day period immediately prior to the date of grant. Initial equity awards are made in connection with initial election or appointment to the Board of Directors, with the target delivered value prorated for the fiscal year based on the date of election or appointment. Initial equity awards vest on or about the one-year anniversary of the grant date. Annual equity awards are made on the date of each Annual Meeting and vest on or about the one-year anniversary of the grant date. Vesting of the RSU awards is subject to acceleration upon the director’s death, disability, retirement, or upon or in connection with a change in control of Ciena. Delivery of the shares upon vesting is subject to any applicable instruction provided by the director under the Deferred Compensation Plan described below.

  53. Director compensation limits

    Director compensation limits Our 2017 Omnibus Incentive Plan (the “2017 Plan”) imposes a $500,000 limit on the compensation that can be awarded to a non-employee director in any given fiscal year, including the sum of (i) cash compensation and (ii) the grant date fair value of equity compensation under the 2017 Plan. This limitation, however, does not apply to the extent a non-employee director has been or becomes an employee of Ciena during such fiscal year. In addition, the Board retains discretion to provide further exceptions for one or more individual non-employee directors in extraordinary circumstances, such as service on a special transaction or litigation committee of the Board, provided that the director that is the subject of such exception may not participate in any decision with respect thereto. Director compensation table The following table and the accompanying footnotes describe the “total compensation” earned by our non-employee directors and Dr. Nettles during fiscal 2023:

For each director other than Ms. Puma, the aggregate grant date fair value in the above table was calculated using the closing price of Ciena common stock on March 30, 2023, the grant date for each such director’s annual award.

This award was granted under the 2017 Plan and vests on September 20, 2024. The aggregate grant date fair values will likely vary from the actual amount ultimately realized by any director based on several factors, including the number of shares that ultimately vest, the effect of any deferral elections, the timing of any sale of shares, and the market price of Ciena common stock at the time of disposition. |

    Deferral of director compensation We maintain the Ciena Corporation Deferred Compensation Plan (the “Deferred Compensation Plan”), which allows our U.S.-based directors (as well as certain U.S.-based senior management employees) to defer elements of their annual compensation. Directors may defer up to 100% of their annual cash retainer and annual equity compensation. Generally, deferral elections may only be made for awards to be granted in a subsequent calendar year. Directors can elect the amount deferred, the deferral period, and the form of distribution of their compensation. If a director elects to defer any portion of an RSU award, upon the vesting of that award, we credit a stock account with the amount deferred. All such accounts are distributed in shares of Ciena common stock. Distributions may be made in a lump sum or installments, as designated by the participating director, subject to early distribution of vested awards in a lump sum in the event of the participant’s death or termination of service, a change in control of Ciena or termination of the plan.

  66. Outstanding Equity Awards at Fiscal Year-End

    Amendment to Ciena’s 2017 Omnibus Incentive Plan Overview We are requesting that our stockholders vote in favor of the proposed amendment to our 2017 Omnibus Incentive Plan, which we sometimes refer to in this proposal as the “2017 Plan.” On December 5, 2023, the Board of Directors approved an amendment to the 2017 Plan (i) to increase, by 10.1 million shares, the number of shares of Ciena common stock available for issuance under the 2017 Plan, subject to stockholder approval at the Annual Meeting, and (ii) to increase the recoupment period for misconduct relating to accounting restatements from 12 months to three years. A copy of the proposed amendment to the 2017 Plan is attached as Annex A to this proxy statement. Our 2017 Plan is the only equity incentive compensation plan under which we currently grant equity incentive awards to directors, officers and employees. We have not sought stockholder approval for an increase in available shares since our 2020 Annual Meeting, nearly four years ago. A key part of our People Strategy in recent years has been advancing our goals of (i) promoting a strong alignment of interest between our stockholders and employees and (ii) offering compelling compensation and benefits that make Ciena an employer of choice in the talent markets in which we compete. To that end, we have significantly expanded the population of employees eligible for and receiving equity incentive awards, particularly within technology roles in engineering and sales, and have grown the number of employees receiving equity awards from approximately 21% in fiscal 2020 to approximately 50% in fiscal 2024. We believe that this approach advances our business and the interests of our stockholders and we intend to continue to invest in our employees through equity compensation. Why you should vote for the 2017 Plan Amendment We believe that the 2017 Plan is important to our continued growth and success. The purpose of the 2017 Plan is to attract, motivate and retain highly qualified officers, directors, key employees and other key individuals. We believe that providing these individuals an opportunity to acquire a direct proprietary interest in the operations and future success of Ciena will motivate them to serve Ciena and to expend maximum effort to improve our business and results of operations. We believe that equity awards under the 2017 Plan are a valuable incentive to participants and benefit stockholders by aligning more closely the interests of participants in the 2017 Plan with those of our stockholders. We believe that our usage of the 2017 Plan illustrates our commitment to best practices in equity compensation, prudent use of limited resources and the promotion of a strong alignment with stockholder interests, as exhibited by our awards and plan design. We ask stockholders to vote for the proposed amendment to the 2017 Plan for the following reasons:

  67. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | We manage our use of equity incentive awards carefully and maintain a reasonable “burn rate.” |

  68. Outstanding Equity Awards at Fiscal Year-End

    The Compensation Committee carefully monitors our total dilution, burn rate and equity expense to ensure that we maximize stockholder value and exercise prudence by granting only such number of equity awards as we deem necessary to attract, reward and retain our employees. Burn rate is defined as the number of shares subject to equity awards issued in a fiscal year as a percentage of Ciena’s weighted average shares outstanding. Ciena’s three-year average burn rate of 1.76%, or 3.53% taking into account adjusted full value shares, is considerably lower than the 4.03% burn rate benchmark used by Institutional Shareholder Services (“ISS”) to assess companies in our industry.

  69. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | We mitigate the dilutive effect of our equity awards. |

  70. Outstanding Equity Awards at Fiscal Year-End

    Our practice is to repurchase and retire shares of common stock to satisfy employee tax withholding obligations due upon vesting of stock unit awards, instead of satisfying these obligations through directed open market sales. During fiscal 2023, we repurchased approximately $38.5 million in shares of common stock in satisfaction of such tax withholding obligations. In addition, since December 2017, we have maintained stock repurchase programs that further mitigate dilution to our stockholders from our equity grants under the 2017 Plan. Under our current stock repurchase program, which was announced in December 2021, we are authorized to repurchase up to $1.0 billion of our common stock. From the commencement of that program through the end of fiscal 2023, we repurchased over $750 million, or approximately 14.1 million shares of our common stock. These practices have resulted in a significant reduction in the dilutive effect of our equity awards.

  71. Outstanding Equity Awards at Fiscal Year-End

    | 32 | 2024 Proxy Statement |

  72. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | Ciena’s equity “overhang” is reasonable compared to peers. |

  73. Outstanding Equity Awards at Fiscal Year-End

    Overhang is defined as stock awards and option awards outstanding, plus shares remaining available for grant under the 2017 Plan. The Compensation Committee carefully monitors our equity overhang and considers Ciena’s overhang as compared to its peers. In addition, Ciena’s equity overhang at December 22, 2023 includes only approximately five thousand shares underlying stock options, primarily assumed via acquisition, as Ciena has not granted stock options broadly in many years. The weighted average remaining term of our outstanding stock options is 0.3 years. None of our stock options outstanding at December 22, 2023 were “out of the money” (i.e., having an exercise price above the current trading price of our common stock).

  74. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | Equity awards made to our executive team in recent years have included a sizable at-risk performance based component. |

  75. Outstanding Equity Awards at Fiscal Year-End

    In recent years, our Compensation Committee has allocated a significant percentage (60% for our CEO and approximately 50% for our other executive officers) of its targeted equity compensation to our executive team in the form of performance-based equity, both PSUs and MSUs, reflecting our commitment to using equity awards as a significant part of our approach to performance-based compensation.

  76. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | Equity incentive awards are an important part of our overall compensation philosophy. |

  77. Outstanding Equity Awards at Fiscal Year-End

    As discussed in the “Compensation Discussion and Analysis” section of this proxy statement, equity incentive awards are a critically important component of our compensation program. As part of our efforts to support our workforce, in recent years we have taken steps to deliver equity awards deeper into the organization and to more employees, particularly in engineering and sales functions. Even with this change, which we intend to continue going forward, we have still maintained reasonable burn rate and overhang metrics. Our Compensation Committee believes that our ability to grant equity incentive awards to employees is an important factor in our ability to attract, retain and motivate key employees. Our Compensation Committee believes that equity compensation provides a strong incentive for our employees to work to grow the business and build stockholder value.

  78. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | As part of our People Promise and talent management strategy, we have expanded the number of employees eligible for and receiving annual equity awards. |

  79. Outstanding Equity Awards at Fiscal Year-End

    In recent years, as part of our ongoing strategy to attract and retain talented personnel at all levels, we began granting annual equity awards deeper within the organization and to more employees, particularly in engineering and sales functions. As a result of this expansion, which was driven in part by the intense competitive dynamics in the labor markets in which we compete, the overall target delivered value of annual equity awards to non-executive employees increased by approximately 247% between fiscal 2020 and fiscal 2024, and the number of non-executive employees who received annual equity awards increased from approximately 21% in fiscal 2020 to approximately 50% in fiscal 2024. We expect to continue this practice going forward.

  80. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | Limited share availability or share exhaustion under the 2017 Plan would harm the competitiveness of our compensation program. |

  81. Outstanding Equity Awards at Fiscal Year-End

    Our Compensation Committee believes that equity-based awards are a particularly effective compensation vehicle, as compared to cash compensation, for a growth-oriented company like Ciena, because such awards align employee and stockholder interests while having a smaller impact on current income and cash flow. Limited shares remaining available for issuance under the 2017 Plan could restrict our ability to grant equity awards that align with our compensation philosophy and negatively impact our ability to offer competitive equity compensation. We believe that our inability to award meaningful equity compensation could result in difficulty attracting, retaining and motivating our employees.

  82. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | The amended 2017 Plan will include an improved and robust clawback mechanism. |

  83. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan includes a mechanism that allows Ciena to recoup or “claw back” certain equity compensation in situations requiring forfeiture under the Sarbanes-Oxley Act of 2002 and circumstances where the grantee engaged in certain misconduct. The proposed amendment to the 2017 Plan would increase the recoupment period for such situations from 12 months to three years. The 2017 Plan also includes a comprehensive clawback provision that subjects awards to mandatory repayment by the grantee in accordance with an award agreement, Ciena’s new Executive Compensation Clawback Policy or any other Ciena recoupment policy, or applicable law.

  84. Outstanding Equity Awards at Fiscal Year-End

    | 2024 Proxy Statement | 33 |

  85. Outstanding Equity Awards at Fiscal Year-End

    | ❖ | The 2017 Plan design highlights Ciena’s commitment to compensation best practices. |

  86. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan includes several key features described below that are designed to protect our stockholders’ interests and that reflect Ciena’s commitment to best practices and effective management of equity compensation:

  87. Outstanding Equity Awards at Fiscal Year-End

    | • | Plan limits and additional shares |

  88. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan authorizes a fixed number of shares and requires stockholder approval to increase the maximum number of securities that may be issued thereunder. The 2017 Plan does not contain an evergreen provision or other features which periodically add new shares for grant thereunder.

  89. Outstanding Equity Awards at Fiscal Year-End

    | • | Compensation limits |

  90. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan contains limitations on the maximum number of shares that may be awarded to, and the maximum amount that may be earned by, any individual under the 2017 Plan in any 12-month period, as well as a limitation on the compensation that may be awarded to a non-employee director in any fiscal year.

  91. Outstanding Equity Awards at Fiscal Year-End

    | • | Application of fungible share ratio for counting full value awards |

  92. Outstanding Equity Awards at Fiscal Year-End

    Under the 2017 Plan, every share underlying RSUs, MSUs, PSUs, and other full value awards is subject to a fungible share ratio that reduces the number of shares remaining available for issuance under the plan by a factor greater than one. The fungible share ratio is 1.31 shares for each full value share awarded.

  93. Outstanding Equity Awards at Fiscal Year-End

    | • | Reasonable share counting; no liberal share recycling |

  94. Outstanding Equity Awards at Fiscal Year-End

    In general, when awards granted under the 2017 Plan are forfeited, expire or are canceled without having been fully exercised, or are settled in cash, the shares reserved for those awards will be returned to the share reserve and will be available for future awards. However, shares of common stock that are delivered to the grantee or withheld by Ciena as payment of the exercise price in connection with the exercise of a stock option or payment of a tax withholding obligation in connection with any award, or are purchased by Ciena with proceeds from option exercises, are not returned to the share reserve.

  95. Outstanding Equity Awards at Fiscal Year-End

    | • | Minimum vesting period |

  96. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan provides that awards granted under the plan may not vest in full in less than one year from the date of grant. This minimum vesting period is subject to exception solely where vesting has occurred due to (i) a grantee’s death or disability, or (ii) a change in control of Ciena. Only a limited number of shares, equal to five percent (5%) of the shares authorized under the 2017 Plan, may be granted with (or subsequently modified to contain) terms that do not meet the minimum vesting period restrictions above. In administering the 2017 Plan, our Compensation Committee has determined and agreed to adhere to an interpretation of this provision such that ratable vesting within one year is not permissible under this minimum vesting provision except as set forth in (i) and (ii) above. The additional shares authorized by this amendment will be subject to these same minimum vesting requirements.

  97. Outstanding Equity Awards at Fiscal Year-End

    | • | No discount stock options or stock appreciation rights (SARs) |

  98. Outstanding Equity Awards at Fiscal Year-End

    All stock options and stock appreciation rights will have an exercise price equal to or greater than the fair market value of our common stock on the date the stock option or stock appreciation right is granted.

  99. Outstanding Equity Awards at Fiscal Year-End

    | • | No repricing |

  100. Outstanding Equity Awards at Fiscal Year-End

    Under the 2017 Plan, repricing of stock options and SARs (including reduction in the exercise price of stock options or replacement of an award with cash or another award type) is prohibited without stockholder approval.

  101. Outstanding Equity Awards at Fiscal Year-End

    | • | Change in control definition |

  102. Outstanding Equity Awards at Fiscal Year-End

    The 2017 Plan has a definition of change in control (referred to as a “corporate transaction” in the 2017 Plan) that we believe would not be considered a liberal change in control vesting risk by ISS.

  103. Outstanding Equity Awards at Fiscal Year-End

    | • | No dividends on unvested equity |

  104. Outstanding Equity Awards at Fiscal Year-End

    Under the 2017 Plan, while Ciena may grant restricted stock awards that include the right to dividends and RSUs, MSUs and PSUs that include dividend equivalent rights, no dividends or dividend equivalent rights will become payable until the corresponding restricted stock award, RSU, MSU or PSU vests.

  105. Outstanding Equity Awards at Fiscal Year-End

    | 34 | 2024 Proxy Statement |

  106. Outstanding Equity Awards at Fiscal Year-End

    | • | Stockholder approval required for certain amendments |

  107. Outstanding Equity Awards at Fiscal Year-End

    Amendments that materially increase the benefits under the 2017 Plan (including changing the vesting restrictions described above), that materially increase the aggregate number of shares that may be issued under the plan, or that materially modify the requirements for participation in the plan are prohibited without stockholder approval. Equity awards outstanding and available The table below includes information as of December 22, 2023 with respect to our (i) equity incentive awards outstanding and (ii) shares remaining available for grant under our 2017 Plan:

  111. Equity Awards Outstanding and Available Summary

    | (2) Ciena has not granted stock options broadly in many years. All of the stock options outstanding were granted under legacy or acquired equity plans prior to the adoption of the 2017 Plan. None of the stock options outstanding were “out of the money” (i.e., having an exercise price above the current trading price of our common stock). |

  112. Equity Awards Outstanding and Available Summary

    As of December 22, 2023, the market value of a share of our common stock was $44.17, which was the closing price of our common stock on that date on the NYSE. The amendment to the 2017 Plan will not be effective unless and until approved by stockholders. Participation and the types of awards under the 2017 Plan are subject to the discretion of the Compensation Committee and, as a result, the benefits or amounts that will be received by any participant or groups of participants if the amendment to the 2017 Plan is approved are not currently determinable. On the record date, there were ten executive officers, eight non-employee directors and approximately 8,650 employees who were eligible to participate in the 2017 Plan. Summary description of the 2017 Plan A description of the provisions of the 2017 Plan is set forth below. This summary is subject to the complete provisions of the 2017 Plan, a copy of which is incorporated by reference as an exhibit to Ciena’s 2023 Annual Report. We encourage you to read the 2017 Plan for additional information. Administration. The 2017 Plan is administered by the Compensation Committee of the Board of Directors. The members of the Compensation Committee qualify as “non-employee directors” for purposes of Rule 16b-3 of the Exchange Act and comply with the independence requirements of the NYSE. Subject to the terms of the 2017 Plan, the Compensation Committee may select grantees to receive awards, determine the types of awards and terms and conditions of awards, prescribe the form of each award agreement evidencing an award, amend, modify or supplement the terms of any outstanding award, and interpret provisions of the 2017 Plan. Members of the Compensation Committee serve at the pleasure of the Board of Directors. The Board of Directors may also appoint one or more separate committees, composed of one or more directors who need not satisfy the independence requirements described above, that may administer the 2017 Plan with respect to grantees, provided such grantees are not Ciena executive officers or directors. The Compensation Committee may delegate its authority under the Plan to the extent permitted by applicable law. Common Stock Reserved for Issuance under the Plan. If stockholders approve this proposal and the 2017 Plan is amended, the shares remaining available for issuance under the 2017 Plan will increase by 10.1 million shares. The number of shares available under the 2017 Plan will also be increased from time to time by: (i) the number of shares subject to outstanding awards granted under our prior equity compensation plans that are forfeited, expire or are canceled without delivery of common stock following the effective date of the 2017 Plan, and (ii) the number of shares subject to awards assumed or substituted in connection with the acquisition of another company. The common stock issued or to be issued under the 2017 Plan consists of authorized but unissued shares or, to the extent permitted by applicable law, issued shares that have been reacquired by Ciena.

    The number of shares of common stock available for issuance under the 2017 Plan will not be increased by any shares tendered or awards surrendered in connection with the purchase of shares of common stock upon exercise of a stock option, any shares of common stock deducted or forfeited from an award in connection with Ciena’s tax withholding obligations, or any shares of common stock purchased by Ciena with proceeds from option exercises. Eligibility. Awards may be made under the 2017 Plan to officers, employees, directors, advisors and consultants of Ciena or its affiliates, and any other individual whose participation in the plan is determined to be in the best interests of Ciena by the Compensation Committee. On the record date, there were ten executive officers, eight non-employee directors and approximately 8,650 employees who were eligible to participate in the 2017 Plan. Effective Date; Term; Amendment or Termination of the Plan. The effective date of the 2017 Plan is March 23, 2017, and the 2017 Plan will terminate ten years after its effective date. The Board of Directors may terminate the 2017 Plan at any time and for any reason. The Board of Directors may also amend the 2017 Plan, provided that amendments will be submitted for stockholder approval to the extent required by the Internal Revenue Code or other applicable laws, rules or regulations. In addition, amendments that materially increase the benefits under the plan (including changing the vesting restrictions described above), that materially increase the aggregate number of shares that may be issued under the plan, or that materially modify the requirements for participation in the plan must be submitted for stockholder approval. Stock Options. The 2017 Plan permits the granting of options to purchase shares of our common stock intended to qualify as incentive stock options under the Internal Revenue Code as well as stock options that do not qualify as incentive stock options. The exercise price of a stock option may not be less than 100% of the fair market value of our common stock on the date of grant. The fair market value is generally determined as the closing price of the common stock on the date of grant. In the case of 10% stockholders who receive incentive stock options, the exercise price may not be less than 110% of the fair market value of our common stock on the date of grant. An exception to these requirements is made for stock options that we grant in substitution for options held by employees of companies that we acquire. In such a case the exercise price is adjusted to preserve the economic value of the employee’s stock option from his or her former employer. The term of each stock option is fixed by the Compensation Committee and may not exceed ten years from the date of grant. If the grantee is a 10% stockholder, the term of an option intended to be an incentive stock option may not exceed five years from the date of grant. Subject to the minimum vesting periods described above, the Compensation Committee determines at what time or times each option may be exercised and the period of time, if any, after retirement, death, disability or termination of employment during which options may be exercised. Options may be made exercisable in installments. The ability to exercise options may be accelerated by the Compensation Committee, subject to compliance with the 2017 Plan. In general, a grantee may pay the exercise price of a stock option by cash, certified check, or other cash equivalent or, with Ciena’s consent, by tendering shares of our common stock or by means of a broker-assisted cashless exercise. No amendment or modification may be made to an outstanding stock option or stock appreciation right if that amendment or modification would be treated as a repricing under the rules of the stock exchange on which the shares of our common stock are listed (currently the NYSE), including replacement with cash or another award type, without the approval of Ciena’s stockholders. Stock options and stock appreciation rights granted under the 2017 Plan may not be sold, transferred, pledged or assigned, other than by will or under applicable laws of descent and distribution. However, the 2017 Plan provides flexibility should we determine to permit limited transfers of non-qualified stock options for the benefit of immediate family members of grantees to help with estate planning concerns. Other Awards. The Compensation Committee may also award:

    Effect of Certain Corporate Transactions. Certain change in control transactions, such as a sale of Ciena, may cause awards granted under the 2017 Plan to vest, unless the awards are continued or substituted for in connection with the change in control. Adjustments for Stock Splits, Stock Dividends and Similar Events. The Compensation Committee will make appropriate adjustments in outstanding awards and the number of shares available for issuance under the 2017 Plan, including the individual limitations on awards, to reflect stock splits and other similar events. Individual Limits. The maximum number of shares of common stock subject to stock options or stock appreciation rights that can be awarded under the 2017 Plan to any person, other than a non-employee director, is one million per year. The maximum number of shares of common stock that can be awarded under the 2017 Plan to any person, other than a non-employee director, other than pursuant to options or stock appreciation right, is one million per year. The maximum amount that may be earned as an annual incentive award or other cash award in any fiscal year by any one person is $5 million and the maximum amount that may be earned as a performance award or other cash award in respect of a performance period greater than 12 months by any one person is $25 million. Limits on director compensation Under the 2017 Plan, the maximum amount of compensation that can be awarded to a director in any given fiscal year is $500,000 in the aggregate, including (i) cash compensation and (ii) the grant date fair value of equity compensation under the 2017 Plan. This limitation, however, does not apply to the extent a director has been or becomes an employee of Ciena during such fiscal year and certain limited exceptions in extraordinary circumstances. Plan benefits The amounts that may be received under the 2017 Plan in the future are not determinable, as the amendment to the 2017 Plan will not be effective unless and until approved by stockholders, and such amounts will depend on actions of the Compensation Committee, the performance of Ciena and the value of our common stock. For details on grants of RSUs, MSUs and PSUs made to our NEOs under the 2017 Plan in fiscal 2023, see the table below entitled “Fiscal 2023 Grants of Plan-Based Awards,” and for more details on grants of RSUs made to our non-employee directors in fiscal 2023, see the table above entitled “Fiscal 2023 Director Compensation Table.” Federal income tax consequences Incentive Stock Options. The grant of an option will not be a taxable event for the grantee or for Ciena. A grantee will not recognize taxable income upon exercise of an incentive stock option (except that the alternative minimum tax may apply), and any gain realized upon a disposition of our common stock received pursuant to the exercise of an incentive stock option will be taxed as long-term capital gain if the grantee holds the shares of common stock for at least two years after the date of grant and for one year after the date of exercise (the “holding period requirement”). Ciena will not be entitled to any business expense deduction with respect to the exercise of an incentive stock option, except as discussed below. For the exercise of an option to qualify for the foregoing tax treatment, the grantee generally must be our employee or an employee of one of our subsidiaries from the date the option is granted through a date within three months before the date of exercise of the option. If all of the foregoing requirements are met except the holding period requirement mentioned above, the grantee will recognize ordinary income upon the disposition of the common stock in an amount generally equal to the excess of the fair market value of the common stock at the time the option was exercised over the option exercise price (but not in excess of the gain realized on the sale). The balance of the realized gain, if any, will be capital gain. Non-Qualified Stock Options. The grant of an option will not be a taxable event for the grantee or Ciena. Upon exercising a non-qualified stock option, a grantee will recognize ordinary income in an amount equal to the difference between the exercise price and the fair market value of the common stock on the date of exercise. Upon a subsequent sale or exchange of shares acquired pursuant to the exercise of a non-qualified stock option, the grantee will have taxable capital gain or loss, measured by the difference between the amount realized on the disposition and the tax basis of the shares of common stock (generally, the amount paid for the shares plus the amount treated as ordinary income at the time the option was exercised). A grantee who has transferred a non-qualified stock option to a family member by gift will realize taxable income at the time the non-qualified stock option is exercised by the family member. The grantee will be subject to withholding of income and employment

  123. Equity Awards Outstanding and Available Summary

    | 2024 Proxy Statement | 37 |

  124. Equity Awards Outstanding and Available Summary

    taxes at that time. The family member’s tax basis in the shares of common stock will be the fair market value of the shares of common stock on the date the option is exercised. The transfer of vested non-qualified stock options will be treated as a completed gift for gift and estate tax purposes. Once the gift is completed, neither the transferred options nor the shares acquired on exercise of the transferred options will be includable in the grantee’s estate for estate tax purposes. In the event a grantee transfers a non-qualified stock option to his or her ex-spouse incident to the grantee’s divorce, neither the grantee nor the ex-spouse will recognize any taxable income at the time of the transfer. In general, a transfer is made “incident to divorce” if the transfer occurs within one year after the marriage ends or if it is related to the end of the marriage (for example, if the transfer is made pursuant to a divorce order or settlement agreement). Upon the subsequent exercise of such option by the ex-spouse, the ex-spouse will recognize taxable income in an amount equal to the difference between the exercise price and the fair market value of the shares of common stock at the time of exercise. Any distribution to the ex-spouse as a result of the exercise of the option will be subject to employment and income tax withholding at this time. Restricted Stock. A grantee who is awarded restricted stock will not recognize any taxable income for federal income tax purposes in the year of the award, provided that the shares of common stock are subject to restrictions (that is, the restricted stock is nontransferable and subject to a substantial risk of forfeiture). However, the grantee may elect under Section 83(b) of the Internal Revenue Code to recognize compensation income in the year of the award in an amount equal to the fair market value of our common stock on the date of the award (less the purchase price, if any), determined without regard to the restrictions. If the grantee does not make such a Section 83(b) election, the fair market value of our common stock on the date the restrictions lapse (less the purchase price, if any) will be treated as compensation income to the grantee and will be taxable in the year the restrictions lapse and dividends paid while the common stock is subject to restrictions will be subject to withholding taxes. Restricted Stock Units. There are no immediate tax consequences of receiving an award of RSUs under the 2017 Plan. A grantee who is awarded RSUs will be required to recognize ordinary income in an amount equal to the fair market value of the shares of our common stock issued to such grantee at the end of the restriction period or, if later, the payment date. Stock Appreciation Rights. There are no immediate tax consequences of receiving an award of stock appreciation rights under the 2017 Plan. Upon exercising a stock appreciation right, a grantee will recognize ordinary income in an amount equal to the difference between the exercise price and the fair market value of our common stock on the date of exercise. Performance and Cash Incentive Awards. The award of a performance or cash incentive award will have no federal income tax consequences for Ciena or for the grantee. The payment of the award is taxable to a grantee as ordinary income. Unrestricted Common Stock. Participants who are awarded unrestricted common stock will be required to recognize ordinary income in an amount equal to the fair market value of the shares of our common stock on the date of the award, reduced by the amount, if any, paid for such shares. Deductibility. For each of the foregoing award types, Ciena will generally be allowed a business expense deduction to the extent the grantee recognizes ordinary income, subject to the limits of Section 162(m) of the Internal Revenue Code and to certain reporting requirements. Section 280G. Certain payments made to employees and other service providers in connection with a change in control may constitute “parachute payments” subject to tax penalties imposed on both Ciena and the recipient under Sections 280G and 4999 of the Internal Revenue Code. In general, when the value of parachute payments equals or exceeds three times the employee’s “base amount,” the employee is subject to a 20% nondeductible excise tax on the excess over the base amount and Ciena is denied a tax deduction for the payments. The base amount is generally defined as the employee’s average compensation for the five calendar years prior to the date of the change in control. The value of accelerated vesting of equity awards in connection with a change in control can constitute a parachute payment. The 2017 Plan contains a modified form of a “safe harbor cap,” which limits the amount of potential parachute payments that a recipient may receive to no more than 299% of the recipient’s base amount, but only if such cutback results in larger after-tax payments to the recipient. Section 409A. Ciena intends for awards granted under the 2017 Plan to comply with Section 409A of the Internal Revenue Code. To the extent a grantee would be subject to the additional 20% excise tax imposed on certain nonqualified deferred compensation plans as a result of a provision of an award under the plan, the provision will be deemed amended to the minimum extent necessary to avoid application of the 20% excise tax.

    Amendment to Ciena’s Amended and Restated Certificate of Incorporation to provide for officer exculpation Overview Our Board of Directors has unanimously adopted, and recommends that stockholders approve, an amendment to Ciena’s Amended and Restated Certificate of Incorporation (the “Charter”) to limit the personal liability of certain senior officers of Ciena as permitted by recent amendments to the Delaware General Corporation Law (the “Amendment”), as discussed further below. Background Effective August 1, 2022, the State of Delaware, which is Ciena’s state of incorporation, adopted amendments to Section 102(b)(7) of the General Corporation Law of the State of Delaware (the “DGCL”) to allow Delaware corporations to exculpate certain of their officers from direct claims for a breach of the duty of care. The DGCL currently provides for exculpation of officers for direct claims, including class actions, and does not provide exculpation for breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, any transaction in which the officer derived an improper personal benefit, or any action brought by or in the right of the corporation. In order to extend the protections of the recently amended Section 102(b)(7) of the DGCL to its officers, a Delaware corporation must affirmatively amend its certificate of incorporation to include such a provision, as the protections do not apply automatically. Currently, our Charter provides for exculpation of directors from direct claims for a breach of the duty of care to the fullest extent permitted by the DGCL. The Amendment would provide both directors and certain officers with exculpation rights to the fullest extent permitted by the DGCL. Rationale We believe that amending and restating our Charter to add liability protection for officers is necessary in order to (i) continue to attract and retain experienced and qualified executives, as similar officer exculpation provisions have been, and are likely to be, adopted by our peers and others with whom we compete for executive talent, (ii) reduce their personal legal exposure; and (iii) help curb corporate litigation and associated insurance costs. We believe all of these are in the best interest of our stockholders. Furthermore, the Amendment would more generally align the protections available to our officers with those protections currently available to our directors. Accordingly, the Board believes that the proposal to extend exculpation to our officers is fair and in the best interests of Ciena and its stockholders. Officers often must make time-sensitive decisions on matters of significant importance to various stakeholders, which gives rise to the risk of legal action that may be based on hindsight. The Amendment would enhance the ability of our officers to make decisions that will maximize Ciena’s value and empower our officers to exercise their business judgment in furtherance of stockholder interests by decreasing concerns about personal risk of legal action while also minimizing the potential distraction posed by frivolous lawsuits and costs that are often borne by us through indemnification or higher insurance premiums. In contrast, failure to adopt the Amendment could impact recruitment and retention of qualified officer candidates, as they may conclude that potential exposure to liability exceeds the benefit of serving as an officer of Ciena. Section 102(b)(7) of the DGCL provides that only certain officers may be entitled to exculpation; namely: (i) the corporation’s president, chief executive officer, chief operating officer, chief financial officer, chief legal officer, controller, treasurer or chief accounting officer; (ii) an individual identified in the corporation’s public filings with the SEC as an NEO; and (iii) an individual who, by written agreement with the corporation, has consented to be identified as an officer for purposes of accepting service of process (collectively, the “covered officers”). The Amendment would permit the exculpation of the covered officers for personal liability for monetary damages in connection with direct claims brought by stockholders for breach of fiduciary duty of care, including class actions, but would not exculpate such officers’ personal liability for monetary damages for breach of fiduciary duty of care claims brought by Ciena itself or for derivative claims brought by stockholders in the name of Ciena. Accordingly, Ciena and our stockholders would still have the ability to hold officers accountable for wrongdoing. In addition, as is currently the case for directors under our Charter, the Amendment would not limit the liability of the covered officers for: (i) a breach of the duty of loyalty; (ii) acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; or (iii) any transaction from which the officer derived an improper personal benefit. In determining the advisability of the Amendment, the Board of Directors considered the narrow class and type of claims from which the covered officers would be exculpated from liability pursuant to Section 102(b)(7) of the DGCL, the limited number of our

  129. Equity Awards Outstanding and Available Summary

    officers to which the protections would apply, and the benefits the Board believes would accrue to Ciena and its stockholders by extending exculpation protection to its senior officers in addition to its directors. Given the potential benefits anticipated to accrue to Ciena, including the associated benefits to our stockholders, and the limited types of claims that would be exculpated, the Board recommends that the stockholders approve the Amendment. Effectiveness of Amendment If the Amendment, in the form attached hereto as Annex B, is approved by the stockholders at the Annual Meeting, it will become effective upon the filing with the Secretary of State of the State of Delaware of a Certificate of Amendment to the Charter, which we would expect to file following the Annual Meeting. Other than the replacement of the existing Article EIGHTH with the proposed Article EIGHTH , the remainder of the Charter will remain unchanged after effectiveness of the Amendment. Even if our stockholders approve the Amendment, our Board retains discretion under Delaware law not to implement it. If the Amendment is not approved by our stockholders, the Charter will remain unchanged.

    Ratification of appointment of independent registered public accounting firm The Audit Committee of the Board of Directors has appointed PricewaterhouseCoopers LLP (“PwC”) as our independent registered public accounting firm to audit Ciena’s consolidated financial statements for fiscal 2024, and is asking stockholders to ratify this appointment at the Annual Meeting. PwC has audited our consolidated financial statements annually since Ciena’s incorporation in 1992. A representative of PwC is expected to attend this year’s Annual Meeting. He or she will have the opportunity to make a statement, if desired, and will be available to respond to appropriate questions. In making its recommendation to the Board of Directors to select PwC as Ciena’s independent registered public accounting firm for fiscal 2024, the Audit Committee considered the quality of PwC’s services, whether the non-audit services provided by PwC are compatible with maintaining the independence of PwC as well as the potential impact to Ciena of a change to its independent registered public accounting firm, and determined that retention of PwC is in the best interests of Ciena and its stockholders. Information regarding fees billed by PwC for our 2022 and 2023 fiscal years is set forth under “Relationship with Independent Registered Public Accounting Firm” below. Our bylaws do not require that stockholders ratify the appointment of our independent registered public accounting firm. We are seeking ratification because we believe it is a matter of good corporate governance. In the event that stockholders fail to ratify the appointment, the Audit Committee will reconsider whether to retain PwC, but may ultimately determine to retain PwC as our independent registered public accounting firm. Even if the appointment is ratified, the Audit Committee, in its sole discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that it is advisable to do so.

    Audit Fees. This category of the table above includes fees for the integrated audit of our annual financial statements, review of financial statements included in our quarterly reports on Form 10-Q, and services that are normally provided by PwC in connection with statutory and regulatory filings or engagements, and services that generally only PwC as the independent registered public accounting firm can provide, such as services for comfort letters and consents. The preparation of Ciena’s audited financial statements includes compliance with Section 404 of the Sarbanes-Oxley Act of 2002 and the preparation by PwC of a report expressing its opinion regarding the effectiveness of our internal control over financial reporting. Audit fees reflect PwC’s integrated audits of financial statements for Ciena. Audit-Related Fees. This category of the table above includes fees for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are not included above under “Audit Fees.” Tax Fees. This category of the table above includes fees for tax compliance, tax advice, tax planning, and other general tax consulting fees. Fees for fiscal 2022 and 2023 primarily include fees related to a study related to research and development tax credits in relevant geographies. Fees for fiscal 2023 also include tax services related to assistance with identification and computation of Section 174 expenditures. All Other Fees. This category of the table above includes fees for services provided by PwC that are not included in the other fee categories reported above. All other fees for fiscal 2022 relate to a pre-implementation assessment for certain anticipated IT system implementations. All other fees for fiscal 2023 relate to subscription fees paid for access to online accounting disclosure research software. Pre-approval of services The Audit Committee pre-approves all services provided by our independent registered public accounting firm, including audit services (such as statutory audit engagements as required under local law of foreign jurisdictions) and non-audit services. For audit services with respect to Ciena, each year our independent registered public accounting firm provides the Audit Committee with an engagement letter outlining the scope of the audit services proposed to be performed during the year, which must be accepted by the Audit Committee before the audit commences. Our independent registered public accounting firm also submits an audit services fee proposal, which must be approved by the Audit Committee before the audit commences. Each year, management also submits to the Audit Committee certain non-audit services for which it recommends the independent registered public accounting firm be engaged to provide, and an estimate of the fees to be paid for each. Management and the independent registered public accounting firm must each confirm to the Audit Committee that the performance of the non-audit services on the list would not compromise the independence of our registered public accounting firm and would be permissible under applicable legal requirements. The Audit Committee must approve both the list of non-audit services and the budget for each such service before commencement of the work. Our management and our independent registered public accounting firm report to the Audit Committee at each of its regular meetings as to the non-audit services actually provided by the independent registered public accounting firm and the approximate fees incurred by Ciena for those services. To ensure prompt handling of unexpected matters, the Audit Committee has authorized its Chair to amend or modify the list of approved permissible non-audit services and fees. If the Chair exercises this delegation of authority, she reports the action taken to the Audit Committee at its next regular meeting. In compliance with the Audit Committee’s internal policy and auditor independence rules of the SEC, all audit and permissible non-audit services provided by PwC to Ciena for the fiscal years 2022 and 2023 were pre-approved by the Audit Committee.

    | Audit Committee Report | | The Audit Committee is composed entirely of non-management directors. The members of the Audit Committee meet the independence and financial literacy requirements of the NYSE and additional, heightened independence criteria applicable to members of the Audit Committee under SEC and NYSE rules. The Audit Committee assists the Board in fulfilling its oversight responsibilities, including by assessing and monitoring the quality and integrity of Ciena’s accounting systems and practices, financial information and financial reporting practices, potential financial, legal and regulatory exposures, systems of internal controls, internal audit function and the independent audit process. Ciena’s management is responsible for Ciena’s financial statements, and its independent registered public accounting firm is responsible for planning and conducting an audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Audit Committee operates under a written charter that describes the scope of its responsibilities, and which is available on the “Corporate Responsibility – Governance Documents” page of the “Investors” section at www.ciena.com. During fiscal 2023, the Audit Committee discussed with PricewaterhouseCoopers LLP (“PwC”), Ciena’s independent registered public accounting firm, the overall scope and plans for the audit. The Audit Committee met regularly with PwC, with and, at times, without management present, to discuss the results of PwC’s examinations, evaluations of Ciena’s internal control over financial reporting and the overall quality of Ciena’s financial reporting practices. The Audit Committee also met with Ciena’s management during fiscal 2023 to consider Ciena’s internal control over financial reporting and Ciena’s disclosure controls and procedures. In this context, the Audit Committee hereby reports as follows: 1. The Audit Committee has reviewed and discussed Ciena’s audited financial statements for fiscal 2023 with management and with PwC. 2. The Audit Committee has discussed with PwC the matters required to be discussed under the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. 3. The Audit Committee has received from PwC the written disclosures and the letter required by applicable requirements of the PCAOB regarding PwC’s communications with the Audit Committee concerning independence, and has discussed with PwC its independence. 4. Based on its review and discussions described in this report, the Audit Committee recommended to the Board of Directors that the audited financial statements for fiscal 2023 be included in Ciena’s Annual Report on Form 10-K for fiscal 2023, for filing with the SEC.

    Certain information in the table concerning beneficial owners other than our directors and executive officers is based on information contained in filings made by such beneficial owners with the SEC. Under SEC rules, beneficial ownership of a class of capital stock includes any shares of such class as to which a person, directly or indirectly, has or shares voting power or investment power and also any shares as to which a person has the right to acquire such voting or investment power within 60 days through the exercise or conversion of any stock option, stock award, or other similar right. If two or more persons share voting power or investment power with respect to specific securities, each such person is deemed to be the beneficial owner of such securities. In computing the percentage ownership of any person, the amount of shares outstanding is deemed to include the amount of shares beneficially owned by such person (and only such person) by reason of such acquisition rights. As a result, the percentage of outstanding shares held by any person in the table below does not necessarily reflect the person’s actual voting power.

    Comparative framework Peer Group. To assist the Committee in the selection of a group of peer companies against which to compare existing and proposed executive compensation levels for fiscal 2023, Compensia used several quantitative and qualitative criteria, including the primary selection and refinement criteria listed below, which were identical to those used in recent years, to review existing and potential peer group companies. Compensia noted its view that, given the limited number of similarly sized business competitors due to industry consolidation, the revenue criterion has the highest relevance in selecting peer companies for purposes of comparing compensation. Following Compensia’s analysis, the Committee noted that in fiscal 2022, the Committee increased the overall size of the peer group in order to provide a broader data set and avoid the overinfluence of any one company, and to better balance Ciena’s positioning with respect to the revenue and market capitalization criteria. The Committee also noted that, for the second consecutive year, there was no need to remove any members of the existing peer group due to either merger or acquisition or falling significantly outside of the Committee’s target ranges for the key criteria. Accordingly, the Committee determined to retain the existing peer group without any changes. Based on this analysis and the selection process set forth below, the Committee determined that the following peer group constituted an appropriate comparative reference for determining executive compensation in fiscal 2023 (the “Peer Group”):

  173. Peer Group comparison

    Peer Group comparison The Committee noted that Ciena was generally aligned with the medians of the Peer Group for the revenue criterion (48%) and the operating income criterion (47%) and below the medians of the Peer Group for the market capitalization criterion (32%) and the headcount criterion (26%). The Committee believed that this represented a reasonable and appropriate balance among the key quantitative criteria, particularly given its view that revenue has the highest relevance in selecting peer companies for purposes of comparing compensation. The Committee also considered the criteria used by ISS and the degree of overlap between Ciena’s existing Peer Group and ISS’s recommended peer group of companies. Market Data. As a comparative framework for the Committee to use in establishing executive compensation for our NEOs, Compensia assembles and analyzes compensation data from public filings, data provided by the Radford High Technology Executive Compensation Survey, and other published market data relating to comparable executive positions in the Peer Group (collectively, the “Market Data”). In considering the Market Data, the Committee recognizes that executive officers in different companies can play different roles, with different responsibilities and scopes of work, even though they may hold similar titles or nominal positions. Moreover, qualitative factors that influence compensation, such as each executive officer’s performance during the period under consideration or their criticality to their respective companies’ business, strategy and objectives are not easily discernible from the Market Data. Accordingly, the Market Data is just one of a number of factors used by the Committee in determining executive compensation and it serves as a frame of reference for compensation. Qualitative factors In any given year, and for any particular NEO, the Committee may consider a range of subjective or qualitative factors in setting the NEOs’ compensation, including:

    | ❖ | our CEO’s recommendations and his assessment of the executive’s performance; |

    | ❖ | the likely cost and difficulty that would be encountered in recruiting a replacement. |

  180. Peer Group comparison

    The Committee’s consideration of any particular factor may range from inapplicable to significant, depending upon the individual and period under consideration. The Committee does not assign relative weights or rankings to such factors. Rather, the Committee relies upon its members’ knowledge and judgment in assessing the various qualitative and quantitative inputs it receives as to each individual and makes compensation decisions accordingly. In determining fiscal 2023 executive compensation, and in addition to the assessment of the Market Data and other specific factors described in the below discussion of the individual elements of compensation, the Committee broadly considered the following qualitative factors in making its compensation decisions for each NEO. Given their tenure, track record and experience, the Committee considered the NEOs to be highly desirable executives and thus potential candidates for recruitment by other companies.

    Internal equity. The Committee seeks to promote strong teamwork and high morale within our executive team. While the Committee does not use any quantitative formula or multiple for comparing or establishing compensation among our executive officers, it is mindful of internal pay equity considerations, and assesses the relationship of the compensation of each executive officer to other members of the executive team. Each fiscal year, the Committee also considers, on a relative basis, the aggregate portion of equity awards, in terms of economic value and allocation of shares, made to the executive team, in comparison to other eligible employees.

    Pay mix In determining the mix of compensation among these elements, the Committee does not assign specific ratios or other relative measures that dictate the total compensation mix to be awarded or targeted to the executive team, or the portion that is either at-risk or otherwise subject to performance. Nevertheless, as illustrated by the charts below, the Committee continued to structure executive compensation in fiscal 2023 so that a significant portion of the target total direct compensation of our CEO and the other NEOs was “at-risk” or performance-based, with the actual value realized subject to the achievement of short-term or long-term corporate and financial performance goals. Approximately 60% of our CEO’s target total direct compensation for fiscal 2023 was structured as “at-risk” performance-based compensation. By linking a significant portion of our executives’ compensation to performance, the Committee emphasized incentive-based variable pay, which is consistent with our pay-for-performance philosophy and creates a strong alignment with long-term stockholder value.

    Target total direct compensation reflects annual base salary, target annual cash incentive opportunity and grant date fair value of fiscal 2023 equity awards. Cash compensation Base salary In determining base salaries for fiscal 2023, the Committee considered that the Market Data showed that the base salaries for all of the executives in the aggregate were below the market median, with variance by individual executive. The base salary for Mr. Smith was above the market median of equivalent positions at the time base salaries for fiscal 2023 were determined, but the Committee recognized that the base salaries of the other NEOs were below the market median of their equivalent positions and acknowledged the ongoing criticality of their respective roles. The Committee’s compensation consultant also advised that many companies were expected to be providing higher merit increases for 2023 in light of market volatility in recent years. Accordingly, for fiscal 2023, the Committee determined not to increase the base salary of Mr. Smith, and to increase the base salaries of Messrs. Moylan, McFeely, Phipps, and Rothenstein, as set forth below.

  196. Annual Base Salary

    Annual cash incentive opportunity The annual cash incentive opportunity for our employees, including the NEOs, is expressed as a percentage of base salary. Because of this correlation, the Committee typically looks at base salary and annual cash incentive compensation in combination, and considers the effect modifications to either element have on the “target total cash compensation” for each individual. The Committee considers potential incentive payments to each NEO at the “target” level (as reflected in “Annual Cash Incentive Bonus Plan” below), together with base salary, in determining the “target total cash compensation” payable to each executive. The Committee considered that the Market Data showed that, if fully paid at the target level, the overall target total cash compensation of our executives in the aggregate was at approximately the 45th percentile of the market, with variance by individual executive, at the time of the Committee’s assessment. Based in part on the planned increases in base salaries described above, the Committee determined that the target annual cash incentive opportunities for the NEOs were reasonable and appropriate, and accordingly did not increase them for fiscal 2023, as set forth below.

    Target total cash compensation The Committee’s decisions with respect to annual base salaries and target annual cash incentive opportunities for fiscal 2023 resulted in target total cash compensation for the NEOs as set forth below.

  200. Target Total Cash Compensation

    The amounts in the table above represent target total cash compensation for fiscal 2022 and fiscal 2023. For amounts actually earned or received by our NEOs during fiscal 2023, see the “Fiscal 2023 Summary Compensation Table” section of the “Executive Compensation Tables” below. Annual cash incentive bonus plan Full-time employees, excluding our employees who receive sales commissions, generally are eligible to participate in our annual cash incentive bonus plan, which pays out a bonus upon the achievement of performance objectives established by the Committee. This plan is the mechanism for delivering the annual cash incentive opportunities discussed above. The bonus plan, which is more fully described in the “Fiscal 2023 Grants of Plan-Based Awards” section of the “Executive Compensation Tables” below, provides the Committee with the flexibility to establish corporate, departmental or individual performance objectives upon which bonus payments are contingent.

  201. Target Total Cash Compensation

    The bonus plan is structured to focus and incent our executive officers on the achievement of a pre-established set of short-term financial and corporate performance objectives. Fiscal 2023 structure. In designing the fiscal 2023 annual cash incentive bonus plan, the Committee decided to continue to use two financial objectives and a set of defined corporate objectives to determine the applicable bonus funding percentage, but to alter their structure for purposes of calculating the bonus funding percentage. Previously, the corporate objectives were used as a multiplier against achievement of financial objectives, but for fiscal 2023 they were used as a third metric. Revenue and adjusted operating income (after taking into account the adjustments described in Financial Objectives below) were again selected as the financial objectives in order to reflect Ciena’s overall emphasis on balancing both top-line revenue growth and bottom-line profitability, and were weighted at 40% and 30%, respectively. The corporate objectives were weighted at 30%. The Committee changed the approach to how corporate objectives impacted bonus funding in order to reflect both the importance of the corporate objectives in advancing Ciena’s strategic and operational initiatives, and their relevance to the work of significant employee populations within Ciena. The Committee also considered that this change would better account for and minimize the impact of market and industry volatility. In previous years, the Committee made changes to the minimum and maximum payouts and slopes for performance below and above the revenue target, initially to enable greater predictability during the COVID-19 pandemic and subsequently to allow for a phased return to the previous revenue minimum and maximum payouts and their corresponding slopes. For fiscal 2023, in order to better account for macroeconomic and industry uncertainty, the Committee made additional changes to the minimum and maximum performance thresholds and payouts, as well as changes to their corresponding slopes within certain ranges of target, resulting in payout slopes that are better aligned to current market practice. Specifically, for fiscal 2023 the Committee: (i) decreased the revenue minimum payout from 60% to 50% and set the performance threshold at 80%; (ii) increased the revenue maximum payout from 180% to 200% and set the performance threshold at 115% (iii) adjusted slopes within 5% of target for revenue performance; (iv) decreased the adjusted operating income minimum payout from 70% to 50% and set the performance threshold at 70%; (v) increased the adjusted operating income maximum payout from 160% to 200% and set the performance threshold at 125%; and (vi) adjusted slopes within 7.5% of target for adjusted operating income performance. The Committee considered that, with these changes, the likely range of outcomes on the financial objectives would result in a fiscal 2023 bonus payout representing a percentage of Ciena’s profit that was reasonably consistent with that in recent years. The applicable bonus funding percentage under the fiscal 2023 annual cash incentive bonus plan was calculated as set forth below, with the maximum amount that could be paid equaling 185% of the target annual cash incentive opportunity ((200% x 40%) + (200% x 30%) + (150% x 30%)). Overall, the fiscal 2023 annual cash incentive bonus plan was designed to balance and align the interests of our employees and stockholders, while incentivizing Ciena’s workforce to drive toward growing revenue and improving profitability and stockholder return.

  203. Target Total Cash Compensation

    Bonus payments are interpolated for performance results falling between the designated levels set forth above. For illustrative purposes only and by way of example, if Ciena had achieved 80% of the revenue target, 92.5% of the adjusted operating income target and five of its six corporate objectives, the applicable annual cash incentive award would have been 84.5% ((50% x 40%) + (90% x 30%) + (125% x 30%)) of the target annual cash incentive opportunity. Financial objectives. As noted above, the Committee believed that the use of two financial performance-based metrics – revenue and adjusted operating income – would provide the most comprehensive and effective indicator of Ciena’s overall operating performance, reduce dependency on a single financial objective, and balance emphasis on top-line and bottom-line performance. The Committee recognized that those measures were two of the most important and frequently reviewed metrics used by our CEO and executive team in managing Ciena’s business. In calculating adjusted operating income, the Committee gives effect to certain adjustments to our GAAP results generally consistent with those reported in our quarterly earnings releases, as well as the cost of the annual cash incentive bonus plan and any sales incentive compensation earned by our global field organization in excess of that budgeted in our annual operating plan. Each of the targets for these financial performance-based metrics was taken directly from our fiscal 2023 operating plan approved by the Board of Directors. Corporate objectives. The fiscal 2023 corporate objectives for the annual cash incentive bonus plan were recommended by management and approved by the Committee. The objectives were aligned with Ciena’s execution imperatives for the fiscal year and were viewed as important to advancing Ciena’s three-year strategic plan, as set forth below.

  208. Attainment of Fiscal 2023 Cash Incentive Bonus

    Equity compensation Factors and process in determining equity awards In determining equity compensation for fiscal 2023, the Committee considered that the Market Data showed that the overall average equity value for our executive officers as compared to the market increased year-over-year, from the 45th percentile of the market the previous year to the 55th percentile of the market at the time of the Committee’s assessment. The analysis of the Committee’s compensation consultant indicated that the annual equity values in the market had increased by an average of 17% year-over-year, as compared to the overall 36% average increase in grant date equity values provided to Ciena’s executive officers. The Committee recognized, however, that the actual market benchmarking was in fact likely lower. Specifically, once established by the Committee, each NEO’s target equity value is calculated into a specific number of shares of Ciena’s common stock based on the trailing 30-day average of Ciena’s closing stock price prior to the grant date. Due to a material increase in the price of Ciena’s common stock leading up to and on the grant date in December 2021, this resulted in a significantly higher grant date fair value in fiscal 2022 than the target equity value awarded to each NEO. The Committee recognized that, consequently, the overall average target equity value for our executive officers was likely below the bottom of its target range of between the 50th and 75th market percentiles for the value delivered to similar executives. Ciena primarily competes with and hires executives from companies that are substantially larger in all relevant comparator metrics, and that the Committee has determined are therefore not appropriate to include in the Peer Group. This dynamic results in the Committee developing a peer group of industry-related companies with whom Ciena does not directly compete but who represent an aggregate financial profile that places Ciena at or about the market median, with revenue as the most relevant criterion. As a result, in order to better reflect market dynamics and Ciena’s resulting challenge in attracting and retaining top executives, the Committee believes that it is appropriate to establish equity values for our executive officers using a third quartile target range for the values delivered to similar executives. Based on Ciena’s business and financial performance, the factors for each individual executive described in “Qualitative Factors” above, and the compensation consultant’s analysis, our CEO prepared recommendations for target equity values for each of the NEOs (other than himself) for the Committee’s consideration. In determining fiscal 2023 equity compensation, and in addition to the qualitative factors described above, the Committee considered, among other things, the following:

  209. Attainment of Fiscal 2023 Cash Incentive Bonus

    | ❖ | our CEO’s assessment of the overall responsibilities, performance, experience, expertise and value to Ciena of each individual, as well as the criticality of each position and any concerns with respect to retaining the individual; |

  210. Attainment of Fiscal 2023 Cash Incentive Bonus

    | ❖ | the existing, unvested equity holdings of each individual and assumptions relating to future values; |

    The Committee made its own evaluation for our CEO, based upon its assessment of his performance, experience and value to Ciena, as well as consideration of the other factors listed above. Equity awards As described above, based on the Market Data, as well as our methodology for calculating the value of equity awards, the Committee believed that the target equity values delivered the previous year were slightly below the overall market. Accordingly, the Committee established aggregate target delivered values for fiscal 2023 that represented reasonable year-over-year increases in target values, with variance by individual executive based on market comparisons for the applicable position, in order to improve alignment with the market.

    In order to ensure continued alignment between the compensation of our executive officers, Ciena’s business and financial performance, and stockholder returns, the Committee decided to deliver this aggregate target equity value through a mix of equity vehicles, consistent with the equity allocation used in recent years. Specifically, the fiscal 2023 equity awards for our executive officers included a combination of restricted stock units (RSUs), performance stock units (PSUs) and market stock units (MSUs), the key elements of which are set forth below.

  218. Attainment of Fiscal 2023 Cash Incentive Bonus

    Once established by the Committee, each NEO’s target equity value was calculated into a specific number of shares of Ciena’s common stock based on the trailing 30-day average of Ciena’s closing stock price prior to the grant date, with such share amount allocated in a manner consistent with the equity vehicle mix set forth above. The Committee reviewed this approach and acknowledged that it can result in deviations that fluctuate, from year to year, between its targeted equity value and the grant date fair value used for reporting purposes in this proxy statement, based on these different methodologies. As a result, the Committee determined that, beginning in fiscal 2024, the targeted equity value for NEO awards would be calculated into a specific number of shares of Ciena’s stock based on the grant date fair value. For more information on the calculation of grant date fair value in accordance with FASB ASC Topic 718, please refer to the Fiscal 2023 Summary Compensation Table below and its accompanying footnotes. The table below sets forth the specific number of shares underlying the equity awards to each NEO, with the PSU and MSU awards set forth at the target level based on achievement of the goals described below. The table also sets forth the aggregate target value intended by the Committee and the aggregate grant date delivered value of such awards based on (i) for RSU and PSU awards, Ciena’s closing stock price of $50.60 per share on the grant date of December 13, 2022, and (ii) for MSU awards, the Monte Carlo simulation as of the grant date, establishing the future award value in accordance with the valuation methodology of FASB ASC Topic 718.

    RSUs. The Committee used its standard four-year vesting period for the RSUs – one-sixteenth of the grant amount vesting each calendar quarter over a four-year period – in order to promote long-term alignment with stockholders and longer-term decision making that provides an effective balance to the shorter-term incentive provided by annual cash incentive bonus awards. PSUs. The Committee structured the PSUs with a fiscal 2023 performance period. In selecting a one-year period, the Committee sought to achieve a balance between the desire to incorporate a specific performance-based component in the long-term incentive compensation for our executive officers with an acknowledgment of the difficulties inherent in establishing long-term performance goals in an uncertain macroeconomic environment and given the volatile technology and communications networking

  224. Fiscal 2023 Annual Equity Awards

    | 2024 Proxy Statement | 59 |

  225. Fiscal 2023 Annual Equity Awards

    sectors in which we and our customers compete. Although the Committee carefully considered the implications of using a one-year performance period instead of a longer period for this portion of its long-term incentive compensation, it ultimately determined that any related issues were outweighed by the desire to avoid any unintended consequences or limiting Ciena’s flexibility as a result of outdated or inapplicable long-term goals in future years. In recognition of the one-year performance period, the Committee incorporated an additional retention element to the performance equity compensation, whereby any PSU shares that were earned during the fiscal 2023 performance period would be subject to a staggered vesting and delivery schedule in two equal installments over the 12 months following the end of the fiscal 2023 performance period, subject to the individual executive officer’s continued service with Ciena. In establishing this performance equity structure, the Committee was significantly influenced by the fact that it had been using a similar structure for the past several years and that the structure successfully achieved the Committee’s desired objectives for both company performance and long-term incentive compensation for our executive officers. The Committee also considered this structure to be reasonable and appropriate in light of the use of longer term equity awards, including, in particular, MSUs as part of the overall equity allocation for our executive officers. In establishing goals for the PSUs, the Committee sought to align the interests of our executive officers with our stockholders by focusing their efforts on ensuring the longer-term growth of our business while achieving growing profitability. The Committee also sought to avoid metric overlap between the goals for the annual cash incentive bonus plan and the long-term equity compensation for our executive officers. Accordingly, the PSUs were based on two goals for fiscal 2023:

  226. Fiscal 2023 Annual Equity Awards

    | ❖ | $5,115 million in aggregate sales orders; and |

  227. Fiscal 2023 Annual Equity Awards

    | ❖ | $3.50 in adjusted earnings per share. |

  228. Fiscal 2023 Annual Equity Awards

    Each of these goals was derived directly from the targets set forth in our fiscal 2023 operating plan, which was reviewed and approved by the Board of Directors. The PSUs were allocated equally between the two goals, and the Committee considered the prospects for attainment and non-attainment of the PSU performance goals to be equally likely. Any portion of the PSUs not earned by the end of the performance period would be forfeited. The PSUs were designed such that 100% of the shares underlying the award would be earned upon the achievement of 100% of both the sales orders target and the adjusted EPS target. Consistent with our pay-for-performance philosophy, and to closely align the interests of our executive officers with our stockholders and to further incentivize them to overachieve against our fiscal 2023 operating plan, the Committee incorporated upside earning potential to the PSUs for extraordinary performance and downside risk for under-performance against each of the two goals. Specifically, the Committee established the following minimum performance thresholds and maximum number of additional PSUs that could be earned for achievement against the sales orders and adjusted earnings per share targets, as set forth below:

  229. Fiscal 2023 Annual Equity Awards

    | | Aggregate Sales Orders (1/2 of Total PSUs) | | Adjusted Earnings Per Share (1/2 of Total PSUs) | | | | Aggregate Sales Orders ($MM) | Target PSUs Earned (%) | EPS ($) | Target PSUs Earned (%) | | | < $4,092 | 0% | < $2.45 | 0% | | “Threshold” | $4,092 | 50% | $2.45 | 50% | | “Target” | $5,115 | 100% | $3.50 | 100% | | “Maximum” | $5,882 | 200% | $4.55 | 200% |

  230. Fiscal 2023 Annual Equity Awards

    The percentages of target PSUs earned are interpolated on a straight-line basis for results falling between the designated levels set forth above. Based on the above table, no PSUs could be earned for performance below the threshold, and the maximum amount of PSUs that could be earned was 200% of the target number of shares underlying each PSU award. MSUs. To promote a strong alignment of interests with our stockholders, the Committee incorporated a relative stock performance goal as part of the annual equity awards for our executive officers. The MSUs are based on Ciena’s total stockholder return (“TSR”) – i.e., its stock price appreciation – as compared to the total reported return (the “Return”) of the S&P North American Technology-Multimedia Networking Index (the “S&P Networking Index”) over a three-year measurement period covering Ciena’s fiscal 2023 through fiscal 2025 (the “Measurement Period”). The Committee selected the S&P Networking Index as the appropriate comparator index both because it is directly relevant to our business, consisting of several companies in our sector and including Ciena as a constituent, and because its overall performance has been closely correlated to that of Ciena in recent years. For purposes of determining the TSR for Ciena and the Return for the S&P Networking Index, and in order to mitigate the potential impact of stock price volatility, the beginning and ending values for each measure will be determined on an average basis over a period of 90 calendar days prior to both the beginning and the end of the Measurement Period. For the same reasons as with the PSUs, the Committee incorporated upside earning potential to the MSUs for outperformance against the S&P Networking Index and downside risk for underperformance against the S&P Networking Index. Specifically, the applicable percentage of the target number

  231. Fiscal 2023 Annual Equity Awards

    | 60 | 2024 Proxy Statement |

  232. Fiscal 2023 Annual Equity Awards

    of MSUs earned will be determined based on the absolute percentage point difference between Ciena’s TSR as compared to the Return for the S&P Networking Index during the Measurement Period, as set forth below:

  233. Fiscal 2023 MSU Performance Goal

    | Fiscal 2023-2025 Relative TSR (absolute percentage point difference) | Target MSUs Earned (%) | | (50)% | 0% | | Equal | 100% | | ≥50% | 200% |

  234. Fiscal 2023 MSU Performance Goal

    The percentage of target MSUs earned is interpolated on a straight-line basis for results falling between the designated levels set forth above. Based on the above table, the maximum amount of MSUs that can be earned is 200% of the target number of shares underlying each MSU award. However, if Ciena’s TSR during the Measurement Period is negative (as a result of a decline in our stock price during such period), then the executive officer will earn less than 100% of the target number of shares underlying the MSU award. To the extent earned, the MSUs will vest in full in December 2025 following the end of the Measurement Period, subject to the individual executive officer’s continued service with Ciena through the vesting date. Any portion of the MSUs not earned at the end of the Measurement Period will be forfeited. Overall, the Committee believed that nearer-term goals of the PSUs focused on top-line growth and bottom-line cash generation (via the PSU goals of sales orders and adjusted earnings per share), complemented by a longer-term MSU goal focused on relative TSR, is an effective combination that will closely align the interests of our executive officers with those of stockholders and thereby encourage actions expected to enhance stockholder value. Attainment of fiscal 2023 PSUs As noted above, we experienced a significantly reduced flow of sales orders in fiscal 2023, in part due to customer inventory management following the rapid improvement in supply chain conditions and product delivery lead times. This sales order reduction had resulting impacts on our business and financial performance that flowed through to earnings per share. Consequently, we failed to meet the minimum performance threshold for PSU earnout on the aggregate sales order goal, and achieved only a partial PSU earnout of the adjusted earnings per share goal, each as set forth below.

  235. Fiscal 2023 MSU Performance Goal

    Based on the equal weighting of the two goals, 32% of the total PSUs were earned as set forth below. One-half of the PSUs earned during fiscal 2023 vested in December 2023, and the remaining one-half of the PSUs earned will vest in December 2024, subject to continued service with Ciena through the vesting date.

    Attainment of fiscal 2021 MSUs The MSUs granted in December 2020 applied to the three-year measurement period covering Ciena’s fiscal 2021 through fiscal 2023. During that period, Ciena’s average stock price decreased from $47.62 at the beginning of the measurement period to $44.26 at the end of the measurement period, thereby generating a TSR of (7.06)%. During that same period, the average stock price of the S&P Networking Index generated a Return of 25.24%. Based on that performance, Ciena’s TSR underperformed the S&P Networking Index’s Return over the measurement period by 32.30%, which resulted in 35% of the total MSUs being earned as set forth below. By their terms, the earned MSUs vested in their entirety in December 2023.

    Equity award practices We apply a consistent approach in our equity award practices by granting annual equity awards to our executive officers and directors at or around the same time each year. Annual equity awards to our NEOs are made by the Committee, and the grant date of these awards is the same day that the Committee meets to approve the awards. The Committee generally meets, approves and grants annual equity awards to our executive officers promptly following Ciena’s release of earnings for the fourth quarter and fiscal year. This practice began in fiscal 2007 and continued for annual equity awards in fiscal 2023, with the fourth quarter earnings release on December 8, 2022 and executive and non-executive equity awards granted on December 13, 2022. As noted above, beginning in fiscal 2024, targeted equity value for NEO awards will be calculated into a specific number of shares of Ciena’s stock based on the grant date fair value versus a 30-day trailing average.

  242. Fiscal 2021 MSU Awards Earned

  243. Fiscal 2021 MSU Awards Earned

    We also have a requirement that our executive officers and non-employee directors hold 50% of all shares of Ciena common stock acquired from Ciena equity awards (net of any shares withheld for taxes or payment of exercise price) until they achieve the applicable minimum ownership level. Each executive officer and non-employee director is subject to these guidelines, provided he or she has five years to attain the requisite stock ownership from the date such individual first becomes subject to the guidelines. Shares that count toward satisfaction of the stock ownership guidelines include: (i) shares owned outright by the person or his or her immediate family members residing in the same household; (ii) shares held in trust for the benefit of the person or his or her family; (iii) shares held through our Deferred Compensation Plan; and (iv) shares purchased on the open market. Unexercised stock options, whether or not vested, unvested restricted stock units, and unearned and unvested performance stock units or market stock units, do not count toward the satisfaction of the guidelines. The guidelines may be waived, at the Committee’s discretion, if compliance would create hardship or prevent compliance with a court order. In addition to the stock ownership requirements specified above, our CEO is required to hold any net shares of Ciena stock that he receives through the exercise of stock options or SARs for at least one year. Deferred Compensation Plan Our Deferred Compensation Plan allows a select group of management employees in the United States (including our NEOs) to defer up to 75% of their base salary and up to 100% of their other compensation, including annual cash incentive bonuses, commissions and RSU awards. The plan also allows non-employee directors to defer up to 100% of their annual cash retainer and annual RSU awards. The plan does not provide for any matching or discretionary contributions to participants except for restorative matching payments of foregone matching contributions that a participant would have received under the terms of our 401(k) Plan but for the participant’s deferrals into the plan. U.S. Executive Severance Benefit Plan We maintain a U.S. Executive Severance Benefit Plan as part of our efforts to continue to attract and retain top executive talent. This plan, which is governed by the Employee Retirement Income Security Act of 1974, as amended, provides certain U.S.-based employees, including the NEOs and employees of the rank of vice president or above, with certain severance payments and benefits in the event of an involuntary separation of service by Ciena without “cause.” We believe that this plan is necessary to offer competitive executive compensation packages, and that the plan is important for the retention of participants. For additional information about the severance payments and benefits payable under this plan, as well as the estimated value of these payments and benefits for the NEOs, see “Payments Upon Involuntary Separation of Service for Other than Cause” below. Change in control severance agreements Each of our executive officers has a change in control severance agreement with Ciena. We have entered into these agreements upon the initial hiring of senior employees, upon promotion of existing employees to senior executive roles, and when the Committee determines it to be important for the retention of other key employees. As the existing agreements were due to expire in accordance with their terms, in November 2022 each of the NEOs entered into a new change in control severance agreement with Ciena. The new agreements contain the same terms and conditions as the previous agreements and are effective through November 2025, unless earlier terminated. We believe that these severance arrangements are important for retention of key employees and necessary to attract qualified executive officers, who may otherwise be deterred from taking a position with us by the possibility of being dismissed following a change in control of Ciena, particularly given the level of acquisition activity in our industry. Except for the conversion of certain performance-based equity into time-based awards at the target performance level, (i) our CEO receives no benefits under this agreement unless his employment is terminated without cause, or by him for good reason, within 90 days prior to or 18 months following the effective date of a “change in control transaction” (as defined in the agreement), and (ii) the other NEOs receive no benefits under these agreements unless their employment is terminated without cause, or by the executive for good reason, within 90 days prior to or 12 months following the effective date of a change in control transaction. We believe this so-called “double trigger” structure reflects best practice and strikes an appropriate balance between the potential compensation payable to executive officers and the corporate objectives described above. We also believe that were Ciena to engage in discussions or negotiations relating to a corporate transaction that our Board of Directors deems in the interest of stockholders, these agreements would serve as an important tool in ensuring that our executive team remains focused on the consummation of the transaction, without significant distraction or concern relating to personal circumstances such as continued employment. Should any severance payment or benefit be subject to excise tax imposed under federal law, or any related interest or penalties, such severance payments or benefits shall be either (a) paid in full by us or (b) paid in a lesser amount such that no portion of the payments would be subject to the excise tax, whichever results in receipt by the executive officer of a greater after-tax amount. Under this “best choice” mechanism, Ciena would not pay any excise taxes or make any gross-up or similar reimbursement payments related to excise taxes resulting from any severance payment or benefit.

    For additional information about the payments and benefits payable under these agreements, as well as the estimated value of these payments and benefits for the NEOs, see “Potential Payments Upon Termination or Change in Control” below. Clawback policy and provisions In July 2023, the Board approved a new Executive Compensation Clawback Policy (the “Required Clawback Policy”), effective October 2, 2023, that is designed to comply with, and will be interpreted in a manner consistent with, Section 10D of the Exchange Act and the applicable rules of the NYSE. Under the Required Clawback Policy, in the event of an accounting restatement due to Ciena’s material noncompliance with any financial reporting requirement under applicable securities laws, including any required accounting restatement to correct a material error in previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period, Ciena must recover erroneously awarded performance-based compensation previously paid to the Ciena’s executive officers in accordance with the terms of the Required Clawback Policy. Furthermore, under the Required Clawback Policy, Ciena is prohibited from indemnifying any executive officer or former executive officer against the loss of erroneously awarded performance-based compensation and from paying or reimbursing an executive officer for purchasing insurance to cover any such loss. We also maintain compensation recoupment or “clawback” provisions in our 2017 Plan, annual cash incentive plan, and sales incentive compensation plan, which are broader than what is currently required by applicable law and provides for recoupment of certain payments and benefits in the event that Ciena is required to prepare an accounting restatement due to material noncompliance, as a result of misconduct, with any financial reporting requirement under applicable securities laws. Specifically, those executive officers subject to automatic forfeiture under Section 304 of the Sarbanes-Oxley Act of 2002, and any other recipient of covered incentive compensation who knowingly engaged in such misconduct, was grossly negligent in engaging in the misconduct, knowingly failed to prevent the misconduct or was grossly negligent in failing to prevent the misconduct, are required to reimburse Ciena the amount of any payment in settlement of such award earned or accrued during the 12-month period following the first public issuance or filing with the SEC (whichever first occurred) of the financial document that contained such material noncompliance. The proposed amendment to our 2017 Plan would increase the recoupment period for such situations under the 2017 Plan from 12 months to three years. Perquisites policy Under our perquisites policy, our executive officers are eligible for the same benefits as our salaried employees and receive only limited perquisites, generally consisting of annual physical examinations as well as tax preparation and financial planning services, both of which are made available to other senior employees. Retirement benefits For equity awards issued on or after December 13, 2022, when executive officers who are residents of certain countries, including the U.S., U.K., and Canada, retire after age 60 with ten years of service and provide and fulfill 12 months’ notice of their retirement, their granted but unvested RSU awards and a pro-rated amount of their PSU awards and MSU awards will continue to vest per their original vesting schedule. Other employees in these countries will be subject to the same eligibility and notice requirements, but will receive acceleration of their granted but unvested RSU awards upon retirement. During the retirement notice period, employees, including executive officers, are not eligible for additional equity grants. In December 2023, we expanded eligibility for this benefit to cover employees in 18 countries. We believe continued vesting following retirement, rather than acceleration upon retirement, better aligns our executive officers’ interests with stockholders beyond the date such executive officer retires from Ciena. We believe that these provisions benefit Ciena by giving us increased visibility into eligible employees’ retirement plans and allowing for enhanced succession planning and knowledge transfer. As of October 28, 2023, Messrs. Smith, Moylan, and McFeely met the eligibility requirements for continued vesting upon retirement for awards issued on or after December 13, 2022. During fiscal 2023, and effective for periods starting with the fiscal 2024 performance cycle, we introduced a similar benefit in our annual cash incentive bonus plan, under which employees, including our NEOs, who retire after age 60 with ten years of service and provide and fulfill 12 months’ notice of their retirement will be eligible to receive cash incentive bonus awards based on actual performance and pro-rated to reflect the total percentage of days they were employed during the relevant bonus period. Required reimbursement policy We maintain a policy requiring our executive officers to reimburse certain costs associated with any personal use of items such as corporate tickets to sporting or cultural events and personal use of any corporate membership at a golf or similar club. Specifically, any executive officer who makes personal use of such tickets is required to reimburse Ciena for the face value of the tickets used. Any executive officer who makes personal use of a club in which Ciena has a corporate membership must reimburse Ciena for the cost of any meals, merchandise, greens fees, lessons and other charges associated with his or her use and, in

    | (2) The amounts set forth in the “Stock Awards” column represent the aggregate grant date fair value of RSU, PSU and MSU awards granted during the fiscal years noted above, computed in accordance with FASB ASC Topic 718. Aggregate grant date fair values reported above do not reflect sale or forfeiture of shares to fund tax withholding in accordance with the terms of the award agreement and will likely vary from the actual amount ultimately realized by any NEO based on a number of factors, including the number of shares that are earned and ultimately vest, the timing of vesting, the timing of any sale of shares and the market price of Ciena common stock at that time. For RSUs, we calculate grant date fair value by multiplying the number of shares underlying the award by the closing price per share of Ciena common stock on the grant date. Assumptions used in determining the grant date fair value of PSUs and MSUs are set forth in Note 24 to our consolidated financial statements included in our 2023 Annual Report. Assuming the maximum future payout under the PSUs and MSUs, the aggregate grant date fair value in the “Stock Awards” column above for fiscal 2023 would have been as follows: $20,950,529 for Mr. Smith; $4,903,342 for Mr. Moylan; $4,256,097 for Mr. McFeely; $4,256,097 for Mr. Phipps; and $3,881,929 for Mr. Rothenstein.

    Equity awards. Equity awards during fiscal 2023 consisted of RSU, PSU and MSU awards. Each such stock award represents a contractual right to receive one share of our common stock. RSU awards granted to the NEOs in fiscal 2023 vest over a four-year term, with one-sixteenth of the grant amount vesting quarterly. PSU awards granted to the NEOs in fiscal 2023 were structured such that 100% of the shares underlying the award would be earned upon the achievement of 100% of both the sales orders target and the adjusted earnings per share target, as more fully described in “Compensation Discussion and Analysis — Equity Awards — PSUs” above. The PSU awards incorporate upside earning potential to the PSUs for extraordinary performance and downside risk for underperformance against each of the two goals. Specifically, the PSU awards are subject to the following minimum performance thresholds and maximum number of additional PSUs that could be earned for achievement against the sales orders and adjusted earnings per share targets, as set forth below:

    Option exercises and stock vested The following table sets forth on an aggregated basis, as to each NEO, information related to stock awards that vested during fiscal 2023. The value realized upon vesting of stock awards is a pre-tax amount determined by multiplying the aggregate number of shares of stock vested for each NEO during fiscal 2023 by the closing market price per share on the corresponding vesting date for that award. Information as to value realized does not take into account reductions related to withholding and other tax-related items, brokerage commissions or fees, or forfeiture or other disposition of shares to cover these amounts. The NEOs do not hold any outstanding stock options and there were no options exercised by NEOs during fiscal 2023.

    Nonqualified deferred compensation The following table shows the executive contributions, earnings and account balances for fiscal 2023 for each NEO participating in the Deferred Compensation Plan. This plan allows a select group of senior management employees in the United States (including our NEOs) to defer up to 75% of their annual base salary and up to 100% of their other compensation, including cash incentive bonuses, commissions and RSU awards. The plan does not provide for any matching or discretionary contributions to participants except for restorative matching payments of foregone matching contributions that a participant would have received under the terms of our 401(k) Plan but for the participant’s deferrals into the plan.

    Potential payments upon termination or change in control This section describes and quantifies the estimated compensation payments and benefits that would be paid to our NEOs in each of the following situations:

  292. Fiscal 2023 Nonqualified Deferred Compensation Table

    | • | upon death or disability; |

  293. Fiscal 2023 Nonqualified Deferred Compensation Table

    | • | upon a Qualifying Retirement (as defined below); |

    | • | upon an involuntary separation of service for other than cause; |

  295. Fiscal 2023 Nonqualified Deferred Compensation Table

    | • | upon a change in control of Ciena; and |

  296. Fiscal 2023 Nonqualified Deferred Compensation Table

    | • | upon a termination of employment following a change in control of Ciena. |

  297. Fiscal 2023 Nonqualified Deferred Compensation Table

    We do not maintain employment agreements with our executive officers, including the NEOs. The information below describes those instances in which our NEOs would be entitled to payments and benefits following a termination of employment and/or upon a change in control of Ciena. Our NEOs are “at will” employees and, except as otherwise described below, they are only entitled to payment of accrued salary and vacation time, on the same terms as provided to our other employees, upon any resignation, retirement that is not a Qualifying Retirement or termination of employment, with or without cause. Except as otherwise noted below, the calculations below do not include any estimated payments for those benefits that we generally make available on the same terms to our full-time, non-executive employees. The estimated payments below are calculated based on compensation arrangements in effect as of the last day of fiscal 2023 and assume that the triggering event occurred on such date. The estimated payment amounts are based on a Ciena common stock price of $41.02 per share, which was the closing market price per share of our common stock on the NYSE on the last trading day of fiscal 2023. Our estimates of potential payments are further based on the additional assumptions specifically set forth in the tables below. Although these calculations are intended to provide reasonable estimates of potential compensation benefits payable, the estimated payment amounts may differ from the actual amount that any individual would receive upon termination or the costs to Ciena associated with continuing certain benefits following termination of employment. Payments upon death or disability Stock awards granted under our 2017 Plan and the Ciena Corporation 2008 Omnibus Incentive Plan (the “2008 Plan”) provide for the acceleration of vesting of awards following a termination of service resulting from the holder’s death or disability. Acceleration of vesting upon death or disability applies to all awards granted under these plans, including awards to both executive officers and non-executive employees, as well as awards to our NEOs. In the case of RSUs, acceleration of vesting applies to such number of shares that would otherwise vest in the 12 months following a termination of service resulting from the holder’s death or disability. In the case of PSUs and MSUs, acceleration of vesting applies to such number of shares that have been earned, but not yet vested, under the award. In the case of PSUs or MSUs not yet earned or unearned, such awards are considered to have been forfeited and are not subject to any acceleration of vesting upon death or disability under the award agreement. However, beginning with the awards granted in December 2023, PSUs and MSUs not yet earned upon the holder’s death or disability will automatically vest, on a pro-rated basis, based on the number of days the holder was employed during the performance period, with performance assumed at target. None of our NEOs held awards with these provisions as of the end of fiscal 2023. For purposes of the foregoing, a disability is defined as inability to perform each of the essential duties of the applicable person’s position by reason of a medically determinable physical or mental impairment which is potentially permanent in character or which can be expected to last for a continuous period of not less than 12 months. For each NEO, the amount in the table below reflects the value of the NEO’s stock awards that are subject to acceleration of vesting upon death or disability multiplied by $41.02 per share, the closing market price per share of Ciena common stock on the NYSE on the last trading day of fiscal 2023.

  324. Potential Payments Upon “Covered Termination”

    CEO pay ratio disclosure As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our median employee and the annual total compensation of our CEO.

  325. Potential Payments Upon “Covered Termination”

    | CEO Pay Ratio | | | CEO Annual Total Compensation * | $15,431,410 | | Median Employee Annual Total Compensation | $96,546 | | CEO to Median Employee Pay Ratio | 160:1 |

  326. Potential Payments Upon “Covered Termination”

    | * Represents amount of total compensation from Fiscal 2023 Summary Compensation Table |

  327. Potential Payments Upon “Covered Termination”

    Methodology Our CEO pay ratio is an estimate calculated in a manner consistent with SEC rules and based upon our reasonable judgment and assumptions. Our methodology and process is explained below:

  328. Potential Payments Upon “Covered Termination”

    | ❖ | Determination of Employee Population. We began with the total population of all global employees of Ciena as of September 1, 2023, including full-time and part-time employees, interns and temporary workers on our payroll, and our Executive Chair, but excluding our CEO. |

  329. Potential Payments Upon “Covered Termination”

    | ❖ | Identification of Median Employee. We selected the aggregate of (a) annualized base salary as of September 1, 2023, (b) the target cash incentive compensation for employees eligible under our Cash Incentive Bonus Plan or Sales Incentive Compensation Plan, as applicable, and (c) the target delivered value for equity awards granted to employees as part of our annual equity awards in December 2022, as the consistently applied compensation measure to identify our median employee. We totaled the amounts and applied an exchange rate as of September 1, 2023 to convert amounts denominated in international currencies into U.S. dollars, and then identified the median employee. We did not make any cost of living adjustments or full time equivalent adjustments. Using this methodology, we determined that the median employee was a full-time employee located in Canada. |

  330. Potential Payments Upon “Covered Termination”

    | ❖ | Calculation of CEO Pay Ratio. We calculated our median employee’s annual total compensation for fiscal 2023 according to the SEC’s instructions for preparing the Summary Compensation Table. We applied an exchange rate of 1 CAD to 0.0.720773 USD as of October 28, 2023, in order to convert the median employee’s earnings that were denominated in Canadian dollars into U.S. dollars. We then calculated our CEO’s annual total compensation according to the SEC’s instructions for preparing the Summary Compensation Table and calculated the ratio between the two numbers. |

  331. Potential Payments Upon “Covered Termination”

    The disclosure presented above is a reasonable estimate. Because the SEC rules for identifying the median employee and calculating the pay ratio allow companies to use different methodologies, exemptions, estimates and assumptions, this disclosure may not be comparable to the pay ratio reported by other companies.

    Pay versus performance The following tables and related disclosures have been prepared in accordance with Item 402(v) of Regulation S-K, and do not necessarily reflect the economic benefit actually earned, received, or realized by our NEOs, the method by which the Compensation Committee makes compensation determinations, or how the Compensation Committee views the link between Ciena’s performance and NEO compensation. For example, a significant portion of “compensation actually paid” relates to changes in fair value of unvested awards over the course of each year, and the ultimate value realized by NEOs from unvested equity awards is not determined until the awards vest.

Revenue and Adjusted Operating Income are the financial performance measures used to determine performance-based cash bonuses under the Annual Cash Incentive Bonus Plan, aggregate sales orders and adjusted earnings per share are the financial performance measures used to determine the earning of PSU awards, and total stockholder return is the financial performance measure used to determine the earning of MSU awards. See “Compensation Discussion and Analysis” above for a further description of our executive compensation program.

    Annual advisory “say-on-pay” vote to approve our named executive officer compensation Our Board of Directors recognizes stockholders’ interest in our executive compensation program. In accordance with Section 14A of the Exchange Act and related SEC rules, we are asking stockholders to approve a non-binding advisory resolution on the compensation of our NEOs. We encourage stockholders to read the “Compensation Discussion and Analysis” and “Executive Compensation Tables” in this proxy statement for a more detailed discussion of our executive compensation program and policies, the compensation governance measures undertaken and implemented by our Board of Directors, and the compensation awarded to our NEOs during fiscal 2023. We actively review and assess our executive compensation program in light of the dynamic industry in which we operate, the evolving marketplace in which we compete for executive talent, and changes in compensation governance best practices. We are focused on compensating our executive officers fairly and in a manner that promotes our compensation philosophy.

    Our Board of Directors believes that our executive compensation program has been designed and executed to satisfy these objectives, and that our compensation program is worthy of stockholder support. In considering our executive compensation program for fiscal 2023, we believe it is important to view the Compensation Committee’s decision-making against the backdrop of our overall corporate governance, our fiscal 2023 business and financial performance, and the pay practices of the companies with whom we compete for talent. We have deliberately structured our core compensation principles and practices to align executive compensation with the interests of our stockholders and to avoid certain compensation practices that do not serve our stockholders’ interests. We continue to evaluate and modify these principles and practices as necessary in order to achieve these objectives. In this regard, we believe that stockholders should consider the “Compensation Discussion and Analysis” in this proxy statement, and in particular the “Decision-Making Framework – Executive Compensation Best Practices” therein.

    Policy for related person transactions Ciena did not engage in any related person transactions during fiscal 2023 within the meaning of applicable SEC rules. The Board of Directors has adopted a written Policy for Related Person Transactions. The purpose of the policy is to describe the procedures used to identify, review, approve and disclose, if necessary, any related person transaction or series of transactions in which: (i) Ciena was, is or will be a participant; (ii) the amount involved exceeds $120,000; and (iii) a related person had, has or will have a direct or indirect material interest. For purposes of the policy, a related person is one of the following:

  357. Compensation Actually Paid and Revenue

    | • | any Ciena director, nominee for director or executive officer (as such terms are used in Section 16 of the Exchange Act and the regulations promulgated thereunder); |

  358. Compensation Actually Paid and Revenue

    | • | any person (including any “group” as such term is used in Section 13(d) of the Exchange Act) who is known to Ciena as a beneficial owner of more than 5% of its voting common stock (a “significant stockholder”); or |

  359. Compensation Actually Paid and Revenue

    | • | any immediate family member of a Ciena director, nominee for director, executive officer, or significant stockholder. |

  360. Compensation Actually Paid and Revenue

    Under the policy, all related person transactions above a de minimis threshold are required to be approved or ratified by the Audit Committee, or another committee consisting solely of independent directors. As a general rule, any director who has a direct or indirect material interest in the related person transaction should not participate in the consideration of whether to approve or ratify the transaction. Prior to entering into a related person transaction, the material facts regarding the transaction, including the interest of the related person, must be presented to the Audit Committee for review. The Audit Committee will consider whether the related person transaction is advisable and whether to approve, ratify or reject the transaction or refer it to the full Board of Directors, in its discretion. If the Audit Committee approves a related person transaction, it will report the action to the full Board of Directors, and Ciena will disclose the terms of related person transactions in its filings with the SEC to the extent required.

    General information Our Board of Directors has made these proxy materials available to you via the Internet or, upon your request, has delivered printed versions of these materials to you by mail. We are furnishing this proxy statement in connection with the solicitation by our Board of Directors of proxies to be voted at our 2024 Annual Meeting. The Annual Meeting will be held on March 21, 2024 at 3:00 p.m. Eastern Time, or at any adjournment thereof.

On or about February 8, 2024, we mailed our stockholders a Notice of Internet Availability of Proxy Materials (“Notice”) containing instructions on how to access our proxy materials, including this proxy statement and our Annual Report to Stockholders for fiscal 2023. The Notice also provides instructions on how to vote over the Internet, by mail or by telephone.

Other stockholders, in accordance with their prior requests, have received e-mail notification of how to access our proxy materials and vote over the Internet, or have been mailed paper copies of our proxy materials and a proxy card or a vote instruction form from their bank or broker. Internet distribution of proxy materials is designed to expedite receipt by stockholders, lower the cost of our Annual Meeting, and reduce the environmental impact of our Annual Meeting. However, if you received a Notice by mail and would like to receive a printed copy of our proxy materials, please follow the instructions for requesting such materials contained on the Notice. If you have previously elected to receive our proxy materials electronically, you will continue to receive these materials via e-mail unless you elect otherwise.

    Frequently asked questions Who may vote at the Annual Meeting? The Board of Directors has set January 22, 2024 as the record date for the Annual Meeting. If you were the owner of Ciena common stock at the close of business on January 22, 2024, you may vote at the Annual Meeting. You are entitled to one vote for each share of common stock you held on the record date. A list of stockholders of record entitled to vote at the Annual Meeting will be open to examination by any stockholder, for any purpose germane to the Annual Meeting, during normal business hours for a period of ten days before the Annual Meeting at our corporate offices at 7035 Ridge Road, Hanover, Maryland 21076. Stockholders wishing to examine the list may contact our Corporate Secretary, and arrangements will be made to review the list in person. How many shares must be present to hold the Annual Meeting? A majority of our shares of common stock outstanding as of the record date must be present at the Annual Meeting in order to hold the meeting and conduct business. This is called a “quorum.” On the record date, there were 145,008,717 shares of Ciena common stock outstanding. Your shares will be counted as present at the Annual Meeting if you either attend our online Annual Meeting or properly submit your proxy prior to the Annual Meeting. Why was I mailed a notice regarding the Internet availability of proxy materials instead of a full set of printed proxy materials? Pursuant to the “notice and access” rules adopted by the SEC, we have elected to provide stockholders access to our proxy materials over the Internet. Accordingly, we sent the Notice to all of our stockholders as of the record date. The Notice includes instructions on how to access our proxy materials over the Internet and how to request a printed copy of these materials. In addition, by following the instructions in the Notice, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. Choosing to receive your future proxy materials by email will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it. What proposals will be voted on at the Annual Meeting and how does the Board of Directors recommend that I vote?

  390. Compensation Actually Paid and Revenue

    | Proposals | | Board Vote Recommendation | | 1. | Elect four Class III Director nominees and one Class II Director nominee | FOR each nominee | | 2. | Approve an amendment to the 2017 Omnibus Incentive Plan, including to increase the number of shares available for issuance thereunder by 10.1 million shares | FOR | | 3. | Approve an amendment to Ciena’s Amended and Restated Certificate of Incorporation, as amended, to provide for officer exculpation | FOR | | 4. | Ratify appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for fiscal 2024 | FOR | | 5. | Advisory vote on named executive officer compensation (“Say-on-Pay”) | FOR |

    How will voting on any business not described in this proxy statement be conducted? We are not currently aware of any other business to be acted upon at the Annual Meeting. If any other matters are properly submitted for consideration at the Annual Meeting, including any proposal to adjourn the Annual Meeting, the persons named as proxies will vote the shares represented thereby in their discretion. Adjournment of the Annual Meeting may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time by approval of the holders of common stock representing a majority of the votes present in person or by proxy at the Annual Meeting, whether or not a quorum exists, without further notice other than by an announcement made at the Annual Meeting.

    How many votes are required to approve each proposal? In the case of an uncontested election, our bylaws require that each director be elected by the vote of a majority of the votes cast with respect to that director’s election by holders of shares present in person or represented by proxy at the Annual Meeting. For this purpose, a “majority of the votes cast” means that the number of votes cast “FOR” a director’s election exceeds the number of votes cast “AGAINST” that director’s election, with abstentions and broker non-votes not counted as a vote cast either “FOR” or “AGAINST.” For more information regarding the Board’s required procedures and this majority vote standard, please see our Principles of Corporate Governance and bylaws, which can be found on the “Corporate Responsibility – Governance Documents” page of the “Investors” section of our website at www.ciena.com. In the case of a contested election (i.e., an election in which the number of candidates exceeds the number of directors to be elected), directors will be elected by plurality vote. For this election, the election of directors at the Annual Meeting is uncontested, meaning that the nominees will be elected by a majority of the votes cast, as described above. Approval of Proposals No. 2, 4, and 5 each require the affirmative vote of a majority of shares present in person or represented by proxy at the Annual Meeting and entitled to vote on these proposals, with abstentions having the same effect as a vote “AGAINST” and broker non-votes not counted as a vote either “FOR” or “AGAINST” and having no effect on the outcome of the vote. Approval of Proposal No. 3 requires the affirmative vote of holders of at least 66 2/3% of the voting power of all of the outstanding shares of stock entitled to vote at the Annual Meeting, with abstentions and broker non-votes having the same effect as a vote “AGAINST.” How are votes counted? With regard to the election of each director nominee in Proposal No. 1 and with regard to Proposals No. 2, 3, 4, and 5, each as set forth in this proxy statement, you may vote “FOR,” “AGAINST” or “ABSTAIN”. If you abstain from voting on these proposals, your shares will be counted as present for purposes of establishing a quorum at the Annual Meeting. An abstention will have no effect on the outcome of the election of our directors in an uncontested election, but will have the same effect as a vote “AGAINST” the remaining proposals. What are broker non-votes and how are they counted at the Annual Meeting? Broker non-votes occur when brokers do not receive voting instructions from their customers and do not have discretionary voting authority with respect to a proposal. If you hold shares through a broker, bank or other nominee and you do not give instructions as to how to vote, your broker may have discretionary authority to vote your shares on certain routine items but not on other items. Broker non-votes are counted as present for purposes of determining the presence or absence of a quorum for the transaction of business at the Annual Meeting but will not be counted for purposes of the election of directors and will have no effect on the outcome of the vote on the remaining proposals. What is the difference between holding shares as a “stockholder of record” and as a beneficial owner of shares held in “street name”? If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered the “stockholder of record” with respect to those shares, and the Notice was sent directly to you. If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice or separate voting instructions were forwarded to you by that organization. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account. You should follow the instructions in the Notice or voting instructions provided to you by that organization in order to vote your shares or direct the organization on how to vote your shares.

    Why hold a virtual Annual Meeting over the Internet? We embrace the latest technologies in our business and believe that holding our Annual Meeting virtually over the Internet provides expanded access, improves communication with stockholders, and yields cost savings for Ciena and our stockholders. We ensure that at our virtual Annual Meeting, all attendees are afforded the same rights and opportunities to participate as they would at an in-person meeting. We began holding our Annual Meeting online in 2013. At that time, we considered a number of factors, including the technologies available to us, the cost of our Annual Meeting, and the historical level of stockholder attendance in person, as compared to the use of other communications such as telephone or Internet. We noted at that time that only a very small number of stockholders, generally less than ten each year, attended our Annual Meeting in person. When we considered implementing a fully virtual Annual Meeting in 2013, we reached out to a number of our stockholders and received extensive support. We continue to receive positive feedback from our stockholders as we adopt best practices and new technologies for our Annual Meeting, proxy statement and related materials. We evaluate annually the method of holding the Annual Meeting, taking into consideration the above factors as well as business and market conditions and the proposed agenda items. We continue to believe that holding our Annual Meeting virtually over the Internet is the right approach for our company, as it enables more of our global base of stockholders to participate in our Annual Meeting. How do I vote my shares without participating in the online Annual Meeting? Whether you are a “stockholder of record” or hold your shares in “street name,” you may direct your vote without participating in the online Annual Meeting. If you are a stockholder of record, you may vote by your shares over the Internet or by telephone by following the instructions on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing and submitting your proxy card and returning it by mail. You should sign your name exactly as it appears on the proxy card. If you are signing in a representative capacity (for example, as guardian, executor, trustee, custodian, attorney or officer of a corporation), you should indicate your name and title or capacity. If you are the beneficial owner of shares held in street name, you may be eligible to vote your shares electronically over the Internet or by telephone by following the instructions on the Notice. If you request printed copies of the proxy materials by mail, you may also vote by signing the voter instruction form provided by your bank or broker and returning it by mail. If you provide specific directions on how to vote by mail, telephone or over the Internet, your shares will be voted by your broker or nominee as you have directed. The persons named as proxies are executive officers of Ciena. All proxies properly submitted in time to be counted at the Annual Meeting will be voted in accordance with the directions contained therein. If you submit your proxy without directing how your shares are to be voted, your shares will be voted by the proxy holders in accordance with the recommendations of the Board of Directors set forth above. How do I vote my shares during the online Annual Meeting? Even if you plan to attend and participate in our online Annual Meeting, we encourage you to vote by telephone or over the Internet, or by returning a proxy card following your request of printed materials. This will ensure that your vote will be counted if you are unable to, or later decide not to, participate in the online Annual Meeting. Whether you are a stockholder of record or hold your shares in “street name,” you may vote online at the Annual Meeting. You will need to enter your 16-digit control number (included in your Notice, your proxy card or the voting instructions that accompanied your proxy materials) to vote your shares at the Annual Meeting. What happens if my shares are held in more than one account? If your shares are held in more than one account, you will receive a Notice or separate voting instructions for each account. To ensure that all of your shares in each account are voted, you must vote in accordance with the Notice or separate voting instructions that you receive for each account. May I revoke my proxy and change my vote after I have voted? You may revoke your proxy and change your vote at any time before the final vote at the Annual Meeting. You may revoke your proxy over the Internet or by phone by following the instructions included in your proxy materials, or by submitting a written notice of revocation to Ciena Corporation, 7035 Ridge Road, Hanover, Maryland 21076, Attention: Corporate Secretary. You may also revoke a previously submitted proxy by voting again on a later date over the Internet, by telephone or by signing and returning a new proxy card by mail (only your latest proxy submitted prior to the Annual Meeting will be counted), or by attending and voting at the online Annual Meeting. Your attendance at the Annual Meeting will not automatically revoke your proxy unless you enter your 16-digit control number and vote again electronically at the Annual Meeting.

    What happens if additional matters are presented at the meeting? Management knows of no matters to be presented for action at the Annual Meeting other than those mentioned in this proxy statement, and the deadline under our bylaws for stockholder proposals and director nominations has passed. However, if any additional matters properly come before the Annual Meeting, it is intended that the persons named as proxies will vote on such other matters in accordance with their judgment of the best interests of Ciena. If for any unforeseen reason any of our nominees is not available as a candidate for director, the persons named as proxies will vote for such other candidate or candidates as may be nominated by the Board of Directors. Will the Annual Meeting be webcast? Yes. This year’s Annual Meeting will be a completely virtual meeting and will be webcast live at www.virtualshareholdermeeting.com/CIEN2024. All stockholders may attend and listen live to the webcast of the Annual Meeting. Stockholders as of the record date of the Annual Meeting may electronically vote their shares and submit questions while attending the Annual Meeting over the Internet by using the 16-digit control number included in the Notice, proxy card or the voting instructions that accompanied these proxy materials. A replay of the Annual Meeting audio webcast will be available on our website for approximately one year. How can I submit a question at the Annual Meeting? Stockholders as of the record date of the Annual Meeting may submit questions in advance of the Annual Meeting by visiting www.proxyvote.com and accessing the online pre-meeting forum using the 16-digit control number found on the Notice, proxy card or voting instructions that accompanied these proxy materials. Stockholders may also submit questions while attending the Annual Meeting. As part of the Annual Meeting, we will hold a live question and answer session during which we intend to answer questions submitted in advance of and during the Annual Meeting that are pertinent to Ciena and the items of business at the Annual Meeting, as time permits and in accordance with our annual meeting procedures. Stockholders may submit questions during the Annual Meetingby logging into www.virtualshareholdermeeting.com/CIEN2024 with the 16-digit control number found on the Notice, proxy card or voting instructions that accompanied these proxy materials and typing the question into the “Ask a Question” field. In the unlikely event that the asking of a large number of pertinent questions prohibits Ciena from answering all pertinent questions, the remaining pertinent questions will be answered on the Investor Relations section of Ciena’s website. Questions that are about personal concerns not shared by stockholders generally, including those that relate to employment, product or service issues, or suggestions for product or services, are not pertinent and will not be answered. Where can I find the voting results of the Annual Meeting? The preliminary voting results will be announced at the Annual Meeting. The final voting results will be tallied by the inspector of elections and will be subsequently published by us by the filing of a current report on Form 8-K with the SEC shortly following our Annual Meeting. This filing will also be available on our website at www.ciena.com. Who is soliciting my vote and who will bear the cost of this solicitation? Our Board of Directors is making this solicitation, and Ciena will bear the entire cost of preparing, assembling, printing, mailing and distributing these proxy materials and soliciting votes. We have engaged Alliance Advisors as our proxy solicitor to help us solicit proxies for a fee of $16,000, plus reasonable out-of-pocket expense. Copies of solicitation materials may be furnished to brokers, custodians, nominees and other fiduciaries for forwarding to beneficial owners of shares of Ciena common stock, and normal handling charges may be paid for such forwarding service. Officers and other Ciena employees, who will receive no additional compensation for their services, may solicit proxies by mail, e-mail, via the Internet, personal interview or telephone. Annual Report on Form 10-K A copy of Ciena’s Annual Report to Stockholders for fiscal 2023 (the “Report to Stockholders”), which includes our 2023 Annual Report, has been posted on the Internet along with this proxy statement, each of which is accessible by following the instructions in the Notice. The Report to Stockholders is not incorporated into this proxy statement and is not considered proxy-soliciting material. Ciena filed its 2023 Annual Report with the SEC on December 15, 2023. Ciena will mail without charge, upon written request, a copy of its 2023 Annual Report, excluding exhibits. Please send a written request to Investor Relations, Ciena Corporation, 7035 Ridge Road, Hanover, Maryland, 21076, or access these materials from the “Investors” section of Ciena’s website at www.ciena.com.

    Householding of proxy materials Stockholders residing in the same address who hold their stock through a bank or broker may receive only one set of proxy materials, including the Notice, in accordance with a notice sent earlier by their bank or broker. This practice of sending only one copy of proxy materials, called “householding,” saves Ciena money in printing and distribution costs and reduces the environmental impact of our Annual Meeting. This practice will continue unless instructions to the contrary are received by your bank or broker from one or more of the stockholders within the household. If you hold your shares in “street name” and reside in a household that received only one copy of the proxy materials, you can request to receive a separate copy in the future by following the instructions sent by your bank or broker. If your household receives multiple copies of the proxy materials, you may request that only a single set of materials be sent by following the instructions sent by your bank or broker. Electronic delivery of future proxy materials If you receive your proxy materials by mail, we encourage you to elect to receive future copies of our proxy materials by e-mail.
