  16. Considerations in Evaluating Director Nominees

    Considerations in Evaluating Director Nominees The Governance Committee selects nominees from a broad base of potential candidates and seeks qualified candidates with diverse backgrounds and experience who possess the highest ethical and professional character and will exercise sound business judgment. In identifying and reviewing potential candidates for the board of directors, the Governance Committee considers the individual’s experience in the Company’s industry, the general business or other experience of the candidate, the needs of the Company for an additional or replacement director, the personality of the candidate, diversity, the candidate’s interest in the business of the Company, as well as numerous other subjective criteria. Of greatest importance is the individual’s integrity, willingness to be involved and ability to bring to the Company experience and knowledge in areas that are most beneficial to the Company. It is the Governance Committee’s goal to nominate candidates with diverse backgrounds and capabilities, to reflect the diverse nature of the Company’s stakeholders (security holders, employees, customers and suppliers), while emphasizing core excellence in areas pertinent to the Company’s long-term business and strategic objectives. A candidate must have an employment and professional record which demonstrates, in the Governance Committee’s judgement, that the candidate has sufficient and relevant experience and background, taking into account positions held, and industries, markets and geographical locations served. A detailed description of the criteria used by the Governance Committee in evaluating potential candidates may be found in the charter of the Governance Committee. From time to time the Governance Committee has engaged a third-party search firm to assist in identifying and reviewing candidates for membership on our board of directors.

    Interim Chief Procurement Officer Compensation. In fiscal year 2026, following the departure of certain key supply chain personnel, the Company engaged Mr. Harris to serve as Interim Chief Procurement Officer, reporting to the CEO.

Mr. Harris is a seasoned supply chain executive, and the Board determined his expertise would be valuable in ensuring solid execution and stability until a permanent executive could be engaged. Accordingly, the Company engaged Mr. Harris on an interim basis for compensation consisting of $37,100 per month in cash compensation and $220,000 in equity to be granted at the end of each month with the number of shares calculated by dividing the value based on the average of the volume weighted average trading price of our common stock during the calendar month preceding the grant date.

  49. Executive Summary

    | – | Elimination of strategic progress objectives from the fiscal year 2026 compensation programs | | – | Adoption of a 1-year performance period for the 50% of our PSUs based on EPS, while retaining 3-year cliff vesting, allowing the Compensation Committee to set more aggressive and rigorous targets that fully reflect the market opportunity, while at the same time retaining flexibility as Lumentum navigates rapidly evolving markets |

  50. Executive Summary

    | • | We emphasized performance-based compensation by increasing the performance-share orientation in our CEO equity mix from 50% PSUs / 50% RSUs to 66% PSUs / 34% RSUs | | • | Our revenue exceeded the 300% achievement level for our fiscal years 2024 – 2026 Long-Term Incentive Plan Performance Stock Units (PSUs), resulting in the maximum payout capped at 200% of target | | • | Our fiscal year 2026 Annual Incentive Plan (AIP) for executive officers was paid at 186.3% of target, representing performance at all levels of the Company, including corporate, product category operational performance and manufacturing performance metrics, and for the first time since fiscal year 2022, our AIP was paid entirely in cash to align payouts directly with annual results | | • | We received support from 88.3% of votes cast by our stockholders on our Say on Pay advisory vote in November 2025 and, in engagements since our last annual meeting, stockholders have continued to voice support for our approach to executive compensation |

  51. Fiscal Year 2026 Say-on-Pay Vote and Stockholder Engagement

    | • | Changes to our compensation peer group | | • | Changes to our Annual Incentive Plan (AIP) | | • | Changes to our performance-based Long-Term Incentive Plan (LTIP) |

  52. Actions Taken with Respect to Fiscal Year 2026 Compensation

    | Concerns about overlap between short-term and long-term programs | Desire for relative performance vs. peers to factor directly into compensation | Desire for increased alignment between stockholder value creation and compensation program outcomes | | • We switched from total revenue to an EPS metric in our fiscal year 2026 LTIP PSU design • We added objectively measurable product category operational performance metrics and manufacturing performance metrics to our fiscal year 2026 AIP design • We revised our fiscal year 2026 AIP to pay bonuses entirely in cash rather than a combination of cash and PSUs to align payouts directly with annual financial results | • As reported in our 2024 proxy statement, we initially added relative total stockholder return (rTSR) as a metric (25%) in our LTIP PSU design to align pay with stockholder return and reward better performance compared to our market competitors; in August 2025, in connection with our elimination of strategic progress objectives, we increased the rTSR metric percentage of our 2025 LTIP awards to 33% • For fiscal year 2026, we increased the rTSR metric weighting again to 50% of our fiscal years 2026 – 2028 PSUs | • We added rTSR as a metric in our LTIP PSU design in fiscal year 2025 and increased it to a 50% weighting in fiscal year 2026 • We switched from revenue to an EPS metric in our fiscal year 2026 LTIP PSU design to reinforce the Company’s focus on ramping our manufacturing, supply chain and operations efficiently and cost-effectively to capture market opportunities as well as long-term revenue growth and the bottom-line results that benefit stockholders • We increased the performance-share orientation for our CEO equity mix to 66% PSUs / 34% RSUs | | Concern that non-financial objectives may not be sufficiently rigorous | | | | • We eliminated strategic progress objectives completely from our fiscal year 2026 AIP and LTIP, focusing on financial and other measurable performance objectives as well as rTSR | | |

  53. Actions Taken with Respect to Fiscal Year 2026 Compensation

    | Fiscal Years 2026 – 2028 PSU Changes 1. Increased weighting of relative Total Stockholder Return metric 2. Change in performance metric from total revenue to EPS | |

  54. Philosophy

    | • | Total compensation should attract, motivate, and retain the talent necessary to achieve our business objectives to increase long-term value and drive stockholder returns. | | • | Superior executive talent should be motivated and retained through a strong pay for performance compensation system that provides the opportunity to earn above-average compensation in return for achieving above-average business and financial success. | | • | Where appropriate, executives and employees should participate in shared compensation programs to support consistent priorities and align execution throughout the organization. | | • | Our compensation practices should continue to evolve to align compensation with recognized best practices. | | • | Good compensation program design enables enhanced disclosure to stockholders following completion of the performance period so stockholders can clearly see the link between performance and pay. | | • | Discretion should be eliminated from our executive compensation programs where possible. Where an element of subjectivity can work to increase the linkage between company performance and executive pay and discretion is applied, application of that discretion should be unambiguously communicated to stockholders. |

  55. Philosophy

    | 1. | Maximize business and financial performance and deliver long-term value for our customers, employees, and stockholders; | | 2. | Be indispensable to our customers by designing and manufacturing innovative and market-leading optical and photonic products that enable advanced optical networking, laser, and datacenter technologies and applications; and | | 3. | Align investors, executives, and employees through an agile, accountable, and financial-performance-driven compensation program that is underpinned by strong pay-for-performance practices. |

  56. Overview

    | Assessments / Outcomes from the Decision-Making Process | | | • | Performance Metrics - the Compensation Committee establishes performance metrics for annual incentive awards and performance-based equity awards to support our strategic priorities and with reference to our compensation philosophy | | • | Assessment of Performance - the Compensation Committee assesses overall company performance to established performance metrics | | • | Payouts - the Compensation Committee reviews the results of performance against incentive plan metrics and determines the amounts of any resulting payouts | | • | Assessment of Pay versus Performance - the Compensation Committee regularly reviews achievement forecasts for all active compensation programs, tracks compensation program performance over time, and analyzes pay-versus-performance outcomes for both Lumentum and its peers |

  57. Peer Group

    Peer Group The Compensation Committee, with input from Semler Brossy, annually reviews the compensation practices of a peer group of similar companies. The Compensation Committee carefully considers and selects an appropriate group of companies to use for executive compensation review and analysis purposes to provide data that assists it in making decisions on Lumentum’s executive compensation program. In addition to the peer group, the Compensation Committee also reviews market data from the US Radford Survey for information technology companies with comparable revenue size to assess the competitiveness of our executive compensation programs. The Compensation Committee considers multiple factors in selecting appropriate peer companies:

  58. Peer Group

    | • | Market competitors: similar companies from the perspectives of market, scale, and business model | | • | Talent competitors: potential sources and destinations for potential executive talent in the key geographies in which our executives work |

  59. Peer Group

    The Compensation Committee reviews market and talent competitors for potential inclusion in our peer group primarily based on revenue and market capitalization. The Compensation Committee, with the input of Semler Brossy, undertook a substantial rebalancing of the peer group for fiscal year 2025 to ensure that Lumentum’s pay and performance outcomes were aligned versus the appropriate market peer group on a relative basis and approved significant changes to the fiscal year 2025 peer group to reflect our go-forward strategy and to reset the baseline of the peer group to better fit our then-current revenue and market capitalization. In February 2024, when setting criteria for the fiscal year 2025 peer group, the Compensation Committee stated two primary objectives for consideration of Lumentum’s initial positioning against a revised peer group:

  60. Peer Group

    | Revenue 45-55th Percentile | Market Capitalization 40-50th Percentile |

  61. Peer Group

    | | 41 |

  62. Peer Group

    In February 2025, when the Compensation Committee reviewed and set the peer group for fiscal year 2026, the Company’s fiscal year 2025 revenue was expected to remain relatively flat, maintaining near median positioning against the fiscal year 2025 peer group. As a result, the Compensation Committee believed that the fiscal year 2025 peer group would remain reasonably representative of appropriately sized companies in the markets in which we compete for customers and for talent for fiscal year 2026. Moreover, while the Compensation Committee makes changes in the peer group from time to time, the Compensation Committee has endeavored to maintain year-over-year consistency when possible. As a result, based on recommendations from Semler Brossy, the Compensation Committee elected not to change the peer group for fiscal year 2026.

  68. Peer Group Financial Positioning

    Based on the Company’s substantially higher revenue in fiscal year 2026, along with substantially higher growth rates and market capitalization, shareholders should expect that the peer group for fiscal year 2027 has been reset significantly.

  69. Fiscal Year 2026 Executive Compensation Program Elements

    | Element | Description and Purpose | Commentary | | Base Salary | Base salary levels take into consideration position, qualifications, experience, prior salary level, market data, and the base salaries of our other executive officers | • No changes were made to base salaries in fiscal year 2026 for continuing NEOs | | Annual Incentive | Incentive based on achievement of near-term financial and operational objectives Aligns executives with stockholders by promoting success on revenue, operating income, and operational goals | • Individual target incentive opportunities in fiscal year 2026 were changed for only one of our continuing NEOs (See “Fiscal Year 2026 Executive Compensation Program Elements – Fiscal Year 2026 Annual Incentive Plan – AIP Target Incentive Opportunities” below) • Changed the annual incentive plan metrics to incorporate corporate financial metrics (revenue, gross margin and operating income), product category operational performance metrics, and manufacturing performance metrics, incentivizing accountability by our NEOs across all aspects of the organization and aligning executive incentives with the incentives of each of our employee categories • Eliminated the payment of annual incentive compensation in PSUs; earned awards for fiscal year 2026 were paid entirely in cash to align payouts directly with annual financial results | | Long-Term Incentive Plan RSUs | Time-vested RSUs are awarded to promote alignment with stockholders over time | • No changes were made to individual LTIP opportunity levels in fiscal year 2026 for continuing NEOs. • 34% of annual LTIP equity awards were made in RSUs for our CEO and 50% of annual LTIP equity awards were made in RSUs for our other NEOs • Awards vest over 3 years - 1/3 on the first anniversary of grant and quarterly thereafter for two additional years | | Long-Term Incentive Plan PSUs | Performance stock units are intended to reward our NEOs for long-term performance through aggressive financial and relative total stockholder return objectives that we believe will create long-term stockholder value | • 66% of annual LTIP awards were made in PSUs for our CEO and 50% of annual LTIP equity awards were made in PSUs for our other NEOs • For our fiscal year 2026 PSUs, based on stockholder feedback and evolving corporate priorities, we changed the performance metric from revenue to EPS, and we changed the weighting from 67% on revenue and 33% on rTSR to 50% for each of EPS and rTSR • Given the rapid evolution occurring in our industry and markets, we set 1-year EPS performance goals with 3-year cliff vesting, allowing us to set more aggressive and rigorous targets than could be projected over a longer performance period while ensuring focus on retention • We continue to set rTSR goals as 3-year performance goals |

  70. Performance Metrics and Target Setting

    Performance Metrics and Target Setting The Compensation Committee reviews and selects the performance metrics used in Lumentum’s compensation programs for both the Annual Incentive Plan and the Long-Term Incentive Plan with the following key principles in mind:

  71. Performance Metrics and Target Setting

    | • | Value creation. The Compensation Committee selects metrics that map most directly to Lumentum’s three long-term strategic and business goals and which, when targets are met and/or exceeded, should result in significant stockholder value creation. | | • | Controllability. The Compensation Committee historically has found that input metrics are more effective motivators than output metrics because program participants can take actions to directly influence input metrics. Consequently, where appropriate, the committee selects metrics that are more directly controllable through management and/or the employee population performance. | | • | Sustainable financial results. The Compensation Committee understands that as Lumentum delivers quarterly and annual results, we are also always building for the future. As a result, the committee gives priority to metrics that underpin the delivery of sustainable financial results for our long-term stockholders and stakeholders. |

  72. Performance Metrics and Target Setting

    Our AIP program has a one-year performance period, while our LTIP program for fiscal year 2026 incorporates both one-year financial performance and three-year stock performance periods. Some metrics are more appropriate to a shorter measurement window, others to a longer window. Lumentum’s AIP is a Company-wide program, used to focus and incentivize performance across our entire employee base, from the factory floor to the executive team. Our performance-based LTIP is a program designed specifically for our officer level employees. Some metrics are more relevant to a broad employee population; others are more appropriate and controllable by particular groups within the organization or by the executive population. The Compensation Committee considers all these factors in deciding which metrics to use in which program.

  73. Performance Metrics and Target Setting

    | 44 | 2026 Proxy Statement |

  74. Performance Metrics and Target Setting

    The following performance metrics were selected for use in Lumentum’s fiscal year 2026 AIP and fiscal year 2026 LTIP programs:

  75. Performance Metrics and Target Setting

    | AIP Metrics | | LTIP Metrics | | | Metric | Relation to Our Strategy | Metric | Relation to Our Strategy | | Organic Revenue 25% of fiscal year 2026 AIP | The Compensation Committee believes that our ability to generate Organic Revenue directly reflects our ability to create and sell innovative products, our ability to sustain strong customer relationships and maintain customer relevance, and in most cases, the most effective path to increased return on investment. Increasing organic revenue over time is a significant driver of stockholder value. These business results are directly within the purview of a wide range of employees throughout our organization, including our executives. | Adjusted Organic Earnings Per Share FY 2026 50% of fiscal year 2026 LTIP PSUs | Lumentum’s strategy to drive expansion in the AI and datacenter markets across AI/ML, cloud computing, and bandwidth-intensive applications aims to stimulate both revenue growth and gross margin expansion. The Compensation Committee believes that long-term revenue growth is essential to sustained stockholder value creation, with larger revenue bases tending to lead to efficiencies, gross margin improvement and an accompanying ability to deploy financial resources to R&D and other growth drivers. At the same time, the Compensation Committee believes that equal attention needs to be focused on ramping our manufacturing, supply chain and operations efficiently and cost-effectively, particularly given the market opportunities presented by Lumentum’s strategy. Achievement of organic EPS reflects this balance in a single long-term metric, capturing the impact of revenue and margin as well as the operations necessary to capture the revenue opportunities and reflecting bottom-line return and value for stockholders. The 1-year performance period with extended 3-year vesting allows us to set aggressive and rigorous goals in a rapidly evolving industry. | | Adjusted Organic Gross Margin 25% of fiscal year 2026 AIP | The Compensation Committee believes that Adjusted Organic Gross Margin (adjusted in the same manner as reporting in our earnings releases, and discounting contributions from mid-year acquisitions) reflects our ability, and provides an incentive, to produce our products profitably, driving efficiency and cost optimization in our supply chain and manufacturing operations. | 3-Year Relative Total Stockholder Return FY 2026-28 50% of fiscal year 2026 LTIP PSUs | In the dynamic markets in which Lumentum competes, the Compensation Committee believes that a relative metric can effectively distinguish Lumentum’s performance from overall sector performance, both in up cycles and down cycles. For fiscal year 2026, the Compensation Committee has chosen as a relative metric the relative total stockholder return performance of Lumentum common stock against the S&P Telecom Select Industry Index. | | Adjusted Organic Operating Income 25% of fiscal year 2026 AIP | The Compensation Committee believes that Adjusted Organic Operating Income (adjusted in the same manner as reporting in our earnings releases, and discounting contributions from mid-year acquisitions) is the most appropriate profitability measure through which to incent our employees and that using the non-GAAP adjusted measure is appropriate because it permits consistent period to period comparison. Profitability is a key metric because increasing profitability directly drives stockholder value creation. Rewarding profitable performance motivates an ongoing focus on ensuring we are using our financial resources wisely and effectively. | | |

    | | 45 |

  77. Performance Metrics and Target Setting

    | AIP Metrics | | LTIP Metrics | | | Metric | Relation to Our Strategy | Metric | Relation to Our Strategy | | Product Category Operational Performance Metrics 12.5% of fiscal year 2026 AIP | The Compensation Committee believes that incorporating operational performance metrics for our key product categories, including revenue and cost-related metrics, increases accountability for business results in each of those product categories and enhances the accountability of our NEOs across the entire organization | | | | Manufacturing Performance Metrics 12.5% of fiscal year 2026 AIP | The Compensation Committee believes that it is important to incorporate Company-wide manufacturing performance metrics, including decreasing net spend/absorption variance, reducing scrap and product cost improvement, to reinforce criticality of execution and contribution to profitability | | |

  78. Performance Metrics and Target Setting

    The Compensation Committee recognizes the importance of establishing both realistic and rigorous goals that continue to motivate and retain executives. As such, the committee approves the range of goals for payout at various levels for each selected metric after thorough review, analysis and discussion with the committee’s compensation consultants and executive management. In this process the Compensation Committee considers:

  79. Performance Metrics and Target Setting

    | • | Our annual operating plan, as well as forecasts and multi-year plans | | • | Risks and opportunities summaries as inputs for appropriate goal selection for each metric | | • | Competitive and market share analyses |

  82. AIP Structure

    AIP Structure As discussed above under the heading “Performance Metrics and Target Setting,” the Compensation Committee approved organic revenue, adjusted organic gross margin and adjusted organic operating income as the primary performance measures under the AIP for determining incentive amounts for our NEOs in fiscal year 2026. When setting these goals, we considered scenarios with and without the impact of potential acquisitions to understand how our organic goals related to overall goals for the year. For fiscal year 2026, the bonus pool under the AIP for our NEOs was measured:

  83. AIP Structure

    | • | 25% based on organic revenue for fiscal year 2026, | | • | 25% based on adjusted organic gross margin for fiscal year 2026, | | • | 25% based on adjusted organic operating income for fiscal year 2026, | | • | 12.5% based on objectively measurable key product category operational performance metrics for fiscal year 2026, and | | • | 12.5% based on objectively measurable manufacturing performance metrics, including decrease in net spend/absorption variance, reduction in scrap as a percentage of finished goods output and product cost improvement. |

  84. AIP Structure

    We eliminated the subjective strategic or quality modifier component for the Compensation Committee to adjust AIP payouts from achievement of the performance objectives that existed in prior year AIPs. The maximum amount earnable under the AIP is 200% of target.

  85. AIP Corporate Financial Goals

    AIP Corporate Financial Goals We overachieved against the fiscal year 2026 AIP Corporate financial goals in large part due to strong momentum in revenue across most of our product categories, and especially in the AI/datacenter space, that exceeded what we regarded as challenging goals at the time they were set and a change in product mix that drove significant increases in gross margin and operating income compared to forecast.

  86. AIP Corporate Financial Goals

    | Financial Goal | FY 2026 Actual ($) | Threshold ($) | Target ($) | Maximum ($) | Earned | | | | 0% Payout | 100% Payout | 200% Payout | | | Organic Revenue 25% weight | 3,014M | 1,966M | 2,313M | 2,776M | 200% | | Adjusted Organic Gross Margin 25% weight | 46.0% | 34.8% | 37.8% | 40.8% | 200% | | Adjusted Organic Operating Income 25% weight | 897M | 251M | 411M | 647M | 200% |

  87. AIP Corporate Financial Goals

    The bonus pool created under the AIP with respect to any performance measure is based on a linear interpolation between threshold performance (0% payout) and target performance (100%) and between target performance and maximum performance (200% payout).

  88. AIP Corporate Financial Goals

    | | 47 |

  89. AIP Product Category Operational Performance Metrics

    AIP Product Category Operational Performance Metrics For our employees that focus on particular product categories, our fiscal year 2026 AIP was based 50% on Corporate financial goals and 50% on their particular product category operational performance goals, including revenue and cost-related goals. For our NEOs, the product category operational performance goals roll up into consolidated product category operational performance goals, and our NEOs are measured against achievement of those consolidated operational performance goals. Our product category operational performance goals involve highly confidential, competitively sensitive information, including product-specific strategies that if disclosed could cause irreparable competitive harm by providing competitors with insight into our internal processes and business initiatives as well as business strategies. At the time those performance goals were set, the Compensation Committee deemed the target performance levels to be realistic “stretch” goals, with a maximum payout possible only in the event of superior performance. The product category operational performance achievement for fiscal year 2026 on various metrics ranged from 0% to 200%. On a consolidated basis across product categories and across metrics overall achievement was 200%, contributing heavily to the Company’s superior overall financial performance for fiscal year 2026.

  90. AIP Manufacturing Performance Metrics

    AIP Manufacturing Performance Metrics For our employees that focus on manufacturing, our fiscal year 2026 AIP was based 75% on Corporate financial metrics and 25% on manufacturing performance metrics, equally weighted between decreasing net spend/absorption variance, reducing scrap as a percentage of finished goods output, and improving product costs for selected products. Our manufacturing performance goals involve highly confidential, competitively sensitive information, including product-specific cost information and strategies that if disclosed could cause irreparable competitive harm by providing competitors with insight into our internal processes and business initiatives as well as business strategies. As with the product category operational performance metrics, at the time those performance goals were set the Compensation Committee deemed the target performance levels to be realistic “stretch” goals, with a maximum payout possible only in the event of superior performance. The manufacturing performance achievement for fiscal year 2026 on various metrics ranged from 0% to 200%, with an average achievement of 90.5%.

  91. AIP Target Incentive Opportunities

    AIP Target Incentive Opportunities We have designated an AIP target incentive opportunity for each of our executive officers as a percentage of the executive’s annual base salary. This target incentive opportunity for a given fiscal year is multiplied by the payout percentage for that year, as determined by our Compensation Committee, to determine the amount of AIP payment, if any, to the executive for that period. Generally, we establish the initial AIP target incentive opportunities of our executive officers through arm’s-length negotiation at the time of hire, taking into account his or her position, qualifications, experience, prior salary level, market data, and the AIP target incentive opportunities of our other executive officers at similar levels. Thereafter, our Compensation Committee reviews the AIP target incentive opportunity of each NEO annually together with the NEO’s base salary informed by total target cash compensation information for similar positions and titles at companies in our compensation peer group and the survey data. We also consider the input from our management team, as described above. In fiscal year 2026, we made no changes to AIP target incentive opportunities for our continuing NEOs, except for Wajid Ali, whose target incentive opportunity was increased to account for the expansion of his role to include broader operating responsibilities within the Company in addition to his role as CFO.

  92. AIP Target Incentive Opportunities

    | | AIP Target Incentive Opportunity for FY 2025 (as a percentage of base salary) | AIP Target Incentive Opportunity for FY 2026 (as a percentage of base salary) | % Increase | | Michael Hurlston | 130% | 130% | 0.0% | | Wajid Ali | 90% | 100% | 11.1% | | Jae Kim | 75% | 75% | 0.0% | | Vincent Retort | 100% | 100% | 0.0% | | Wupen Yuen | 100% | 100% | 0.0% |

  94. AIP Achievement

    AIP Achievement Following the end of fiscal year 2026, the Compensation Committee reviewed the achievement of the performance measures under the AIP and determined that (i) organic revenue performance was achieved at 130.3% of target, (ii) adjusted organic gross margin performance was achieved at 121.7% of target, and (iii) adjusted organic operating income performance was achieved above 200% of target. Based on the metric weighting, total fiscal year 2026 AIP payouts for our NEOs were at 186.3% of target opportunity as shown in the table below, paid 100% in cash.

  95. AIP Achievement

    | Fiscal Year 2026 AIP Metric | FY 2026 Actual ($) | Payout (%) | | Organic Revenue 25% weight | $3,014M | 200.0% | | Adjusted Organic Gross Margin 25% weight | 46.0% | 200.0% | | Adjusted Organic Operating Income 25% weight | $897M | 200.0% | | Product Category Operational Performance Metrics 12.5% weight | | 200.0% | | Manufacturing Performance Metrics 12.5% weight | | 90.5% | | TOTAL | | 186.3% |

  97. Fiscal Year 2026 Long-Term Incentive Plan

    Fiscal Year 2026 Long-Term Incentive Plan

  98. LONG-TERM INCENTIVES

    LONG-TERM INCENTIVES Objective/Purpose: To promote long-term thinking and long-term value creation, drive achievement of multi-year strategic objectives, align our NEOs’ interests with those of our stockholders, and reward sustained excellence in execution. We use annual equity awards as the primary vehicle to deliver long-term incentive compensation opportunities to our NEOs. On limited occasions, the Compensation Committee may approve additional equity awards to address special situations as they may arise from time to time, such as in connection with new hires, promotions or to provide an additional retention incentive. Our long-term incentives are intended to align the interests of our NEOs with those of our stockholders. Equity awards are subject to time or performance vesting requirements to encourage retention and drive performance.

  99. Fiscal Year 2026 Long-Term Incentive Structure

    Fiscal Year 2026 Long-Term Incentive Structure

  100. Fiscal Year 2026 Long-Term Incentive Structure

    | | • We increased the performance share orientation for our CEO equity mix in fiscal year 2026 to 66% performance stock units (PSUs) / 34% restricted stock units (RSUs) • 50% of PSUs vesting at the end of three years based on the achievement of our EPS objectives for fiscal year 2026 • 50% of PSUs vesting at the end of three years based on the achievement of relative total stockholder return goals for the period from fiscal year 2026 to fiscal year 2028 • RSUs vesting over three years based on continued service |

  101. Fiscal Year 2026 Long-Term Incentive Structure

    The Compensation Committee factored in market and peer practices as well as the Company’s preference for emphasizing performance-based compensation in determining the mix between performance-based and time-based equity awards for fiscal year 2026. In fiscal year 2026, 33% of our CEO’s long-term incentive award was in the form of PSUs with a three-year performance period based on relative total stockholder return (rTSR), 33% of our CEO’s long-term incentive award was in the form of PSUs with a one-year performance period and 3-year time-based cliff vesting, and the remaining 34% of our CEO’s annual equity awards was in the form of time-based RSUs.

  102. Fiscal Year 2026 Long-Term Incentive Structure

    | | 49 |

  103. Fiscal Year 2026 Long-Term Incentive Structure

    In fiscal year 2026, 25% of each of our other NEO’s long-term incentive award was in the form of PSUs with a three-year performance period based on rTSR, 25% of each of our other NEO’s long-term incentive award was in the form of PSUs with a one-year performance period and 3-year time-based cliff vesting, and the remaining 50% of each of our other NEO’s annual equity awards were in the form of time-based RSUs. Time-based RSUs granted to our NEOs in fiscal year 2026 vest 1/3 after one year and quarterly for the next two years thereafter subject to the NEO’s continued service through each vesting date. The rationale for time-based RSUs is primarily retention with an alignment to stockholder interests based on equity valuation. The vesting schedule is consistent with common industry practice in the space in which we compete. Fiscal year 2026 PSUs have performance periods that cover fiscal year 2026 for EPS and fiscal years 2026 – 2028 for rTSR. The Compensation Committee switched from a revenue goal to an EPS goal for the 2026 LTIP to balance in a single long-term metric the importance of revenue growth to sustained stockholder value creation with the attention that the Company needs to focus on ramping its manufacturing, supply chain and operations efficiently and cost-effectively to capture the Company’s market opportunities as it drives expansion in the AI and datacenter markets. Given the rapidly evolving nature of the cloud and AI market, and the photonics industry in particular, as well as the desire to be able to set more aggressive and rigorous goals than could be projected over a longer performance period, the Compensation Committee paired a 1-year performance period with an aggregate of 3-year time-based vesting for the EPS PSUs, which also matches market practice for an EPS metric. At the same time, the Compensation Committee increased the percentage for 3-year rTSR PSUs from 33% to 50% of the PSUs. The Compensation Committee believes this approach balances the ability to set aggressive and rigorous goals for EPS (the one-year on-target EPS goal for fiscal year 2026 was set at more than double fiscal year 2025 EPS) with the inclusion of multi-year holding and multi-year performance requirements, resulting in an overall structure that maximizes linkage between the interests of our stockholders and our NEOs. The PSUs are designed to reward our NEOs for creation of long-term performance through aggressive financial and total stockholder return objectives that we believe will create long-term stockholder value.

    | Metric and Weighting | FY 2026 Adjusted Organic EPS (50%) | 3-Year relative Total Stockholder Return Objective (50%) | | Metric Rationale | EPS reflects the importance of both revenue growth and ramping manufacturing, supply chain and operations to capture our revenue opportunities as well as the bottom-line return and value for stockholders. | Relative total stockholder return, or rTSR, measures the Total Stockholder Return of our common stock against the total stockholder return of the S&P Telecom Select Industry Index, and distinguishes Lumentum’s performance from overall sector performance both in good times and down times. | | Goal Setting | EPS goals and resulting achievement levels are set by the Compensation Committee after consideration of the Company’s annual and long-term operating plans (once those plans have been reviewed and approved by the full Board) and prior year growth and are also evaluated relative to investor community expectations to ensure their appropriateness. | The Compensation Committee worked closely with Semler Brossy to identify rTSR objectives. | | Upside / Downside | The total EPS component can be earned at up to 200% of target. The Compensation Committee established this higher earning potential to recognize the criticality of EPS growth to our financial success. If threshold EPS goals are not met, this portion is earned at 0% of target. | The rTSR objective component can be earned at up to 200% of target if a maximum level of +40% to the index is achieved, at 100% if a target level of 0% to the index is achieved, and at 50% if a threshold level of -40% to the index is achieved. If a threshold level of -40% below the index is not earned, this portion is earned at 0% of target. Performance between threshold and target, or target and maximum will result in vesting of a percentage of units based on linear interpolation between the two performance levels. | | Aggregate PSU earning is capped at 200% of target. | | |

  107. Fiscal Year 2026 Long-Term Incentive Award Target Opportunities

    Fiscal Year 2026 Long-Term Incentive Award Target Opportunities The size of annual equity awards for our NEOs is determined by the Compensation Committee, considering each executive’s role, performance, and data from our compensation peer group and compensation surveys.

  108. Fiscal Year 2026 Long-Term Incentive Award Target Opportunities

    | | Target Value of Equity Awards Granted ($) | Units Awarded(1) | | Michael Hurlston | 10,000,000 | 101,157 | | Wajid Ali | 4,500,000 | 45,520 | | Jae Kim | 2,300,000 | 23,266 | | Vincent Retort | 3,000,000 | 30,347 | | Wupen Yuen | 4,500,000 | 45,520 |

  109. Fiscal Year 2026 Long-Term Incentive Award Target Opportunities

    | (1) The number of actual units per grant award was determined using the volume-weighted average price for July 2025, which was $98.85573. |

  110. Achievement and Vesting of Fiscal Year 2024 PSUs

    Achievement and Vesting of Fiscal Year 2024 PSUs In fiscal year 2024, each NEO’s annual equity awards included PSUs with a three-year performance period, evaluated and potentially vesting after the end of fiscal year 2026. These grants were originally subject to attainment of goals relating to 3-year Total Revenue weighted 70% of the target opportunity, and goals relating to Strategic Progress Objectives measured over a three-year period, weighted 30% of the target opportunity. The performance period for these fiscal year 2024 PSUs runs from the beginning of our fiscal year 2024 to the end of our fiscal year 2026. Total maximum payout for these fiscal year 2024 PSUs (including both Total Revenue PSUs and Strategic Progress Objective PSUs) is capped at 200%. Our 2024 LTIP PSUs were originally granted with 30% of the awards subject to attainment of certain Strategic Progress Objectives, including Product, Sustainability and Human Capital/Leadership goals through fiscal years 2024 through 2026. As described in our 2025 Proxy Statement, in August 2025, in connection with an action removing Strategic Progress Objective goals from our LTIP program, the Compensation Committee approved changes to remove all Human Capital/Leadership goals and to measure the Strategic Progress Objectives for our 2024 LTIP PSUs based on performance through the end of fiscal year 2025. Of the 30% of 2024 LTIP PSUs subject to Strategic Progress Objectives goals, 125% were considered earned and converted into time-based RSUs vesting on continued service through the vesting date for 2024 LTIP PSUs. We believe this action appropriately balanced the objective of removing Strategic Progress Objectives from our LTIP program with recognizing the achievements that had been made at the time of approval. The remaining 2024 LTIP PSUs are based only on the Total Organic Revenue metric, with achievement for that metric capped at 300% and with the combined maximum payout of the Strategic Progress Objective RSUs and the Total Organic Revenue PSUs capped at a payout of 200% of the target shares under the original 2024 LTIP PSUs. These PSUs were the last to provide the opportunity for interim “banking” of a portion of the award based on total revenue performance in fiscal year 2024 and fiscal year 2025. In each of those years, the threshold level of performance for such year’s interim total revenue goal was not met, and as a result no shares were banked. However, based on strong fiscal year 2026 results, Total Organic Revenue achievement in the third year rose to exceed the 300% achievement level. That achievement was then limited by the 200% achievement cap of the original 2024 PSUs when combined with the Strategic Progress RSUs. Achievement on the fiscal year 2024 PSUs is as follows:

  111. Achievement and Vesting of Fiscal Year 2024 PSUs

    | Fiscal Year | Actual ($l) | Threshold ($) | Target ($) | 200% ($) | Maximum ($) | Banked/ Earned | | | | 50% Payout | 100% Payout | 200% Payout | 300% Payout | | | 2024 | 1,359M | 1,400M | $1,550M | | | 0% | | 2025 | 1,645M | 1,650M | 1,850M | | | 0% | | 2026 | 3,014M | 1,800M | 2,090M | 2,288M | 2,483M | 300% |

  114. Achievement and Vesting of Fiscal Year 2024 PSUs

    | (1) Mr. Hurlston was not employed when fiscal year 2024 PSUs were granted; therefore, he was not granted any fiscal year 2024 PSUs. |

  115. Achievement of Fiscal Year 2026 EPS-Based PSUs

    Achievement of Fiscal Year 2026 EPS-Based PSUs The Compensation Committee set the target and maximum achievement levels for the Fiscal Years 2026-2028 EPS-Based PSUs at 221% and 265% of fiscal year 2025 adjusted organic EPS, respectively, which the Committee expected would be very aggressive growth goals. Based on the Company’s significant outperformance in fiscal year 2026, the Company’s fiscal year 2026 adjusted organic EPS was 421% of fiscal year 2025 adjusted organic EPS, resulting in achievement of the Fiscal Years 2026-2028 EPS-Based PSUs significantly exceeding the fiscal year 2026 maximum achievement objective by 60% and resulting in the maximum achievement capped at 200%.

  116. Achievement of Fiscal Year 2026 EPS-Based PSUs

    | Fiscal Years 2026-2028 PSUs EPS Metric | Payout | FY 2026 ($) | | Threshold | 0% | 3.64 | | Target | 100% | 4.55 | | Maximum | 200% | 5.46 | | Actual | | 8.67 | | Earned | | 200% |

  117. Achievement of Fiscal Year 2026 EPS-Based PSUs

    The shares subject to the Fiscal Years 2026-2028 EPS-Based PSUs remain subject to time-based cliff vesting and, provided that the executive continues to remain a service provider of the Company, will vest on August 18, 2028.

  119. Historical AIP and LTIP Achievement

    Historical AIP and LTIP Achievement The Compensation Committee continuously assesses achievement levels of its performance-oriented executive compensation programs, including both annual and long-term incentive programs. We use this information to evaluate how effectively executive compensation programs are aligned with business performance and stockholder experience, to understand how accurately the Company can set both short-term and long-term performance goals, and to judge how effective the Company’s compensation programs are at incenting performance and ensuring retention. Fiscal year 2026 brought another significant increase in payouts under our AIP, with payouts close to the maximum level, aligned with significantly higher returns to our stockholders over the last year. The overachievement in AIP in fiscal years 2025 and 2026 is a change from three previous years of underachievement. Considering the Company’s fiscal and equity performance over the last several years, the Compensation Committee assesses that our AIP programs have been successful in establishing rigorous bonus objectives and in directional alignment of pay with performance. The payout in fiscal year 2026 under our fiscal year 2024 LTIP was also achieved at maximum, reflecting the significant transformation in our business starting in fiscal year 2025 and expanding in fiscal year 2026, despite the trough in business performance that Lumentum and many of our competitors experienced during the first half of that three-year performance period. Similar to the AIP, the Compensation Committee assesses that our LTIP programs have been successful in establishing aggressive absolute long-term business performance goals and have aligned and continue to align pay with performance and stockholder interests, albeit shifted somewhat in time due to the nature of when goals are set, when achievement is recorded, and when compensation is earned for these programs. The Compensation Committee further assesses that the 3-year performance periods allow for executives to recover from down periods with strong performance, as demonstrated by the 2024 PSUs, providing suitable retention power within the executive suite. We also look continuously at forward-looking performance, and we believe that the mix of RSUs, 3-year rTSR PSUs and 1-year EPS PSUs coupled with an additional 2-year time-based cliff vesting, combined with Mr. Hurlston’s bold vision for execution and growth that has so far demonstrated strong results, will continue to provide strong retention. The following graphs show historical payouts under these plans over the past several years and demonstrate the trends described above.

  120. Post-Employment Compensation

    Post-Employment Compensation Our NEOs are provided certain protections in the event of their termination of employment under specified circumstances, including following a change in control of Lumentum. We believe that these protections serve our retention objectives by helping our NEOs maintain continued focus and dedication on their responsibilities to maximize stockholder value, including in the event of a transaction that could result in a change in control. For detail on these protections, see “Mr. Hurlston’s Offer Letter” and “2015 Change in Control and Severance Benefits Plan, as amended” sections below.

  121. Policies and Practices Related to the Grant of Certain Equity Awards

    Policies and Practices Related to the Grant of Certain Equity Awards We do not grant equity awards on a predetermined schedule, but typically approve equity awards at regularly scheduled meetings of our Compensation Committee during open trading windows. We have not granted stock options in the last several fiscal years, other than in connection with the exchange and conversion or replacement of Cloud Light stock options in connection with the acquisition of Cloud Light in November 2023. At this time, we do not have plans to grant stock options in the future, but may later determine to do so. We have not granted any options in anticipation of the release of material, nonpublic information that is likely to result in changes to the price of our common stock, such as a significant positive or negative earnings announcement, and we have not taken material nonpublic information into account when determining the timing or terms of stock options. Similarly, we have not timed, nor do we intend to time, the release of material, nonpublic information for the purpose of affecting the value of executive compensation or for any other purpose.

  122. Summary Compensation Table

    Summary Compensation Table The following table provides certain summary information concerning the compensation awarded to, earned by, or paid to each of our NEOs for the fiscal year ended June 27, 2026 and, to the extent required under the SEC executive compensation rules, the fiscal years ended June 28, 2025 and June 29, 2024.

  124. Summary Compensation Table

    | (1) Actual salary earned during fiscal years 2026, 2025 or 2024, as applicable. | | (2) Amounts shown do not reflect compensation actually received by the NEO. Instead, the amounts shown are the grant date fair value in the period presented as determined pursuant to FASB ASC Topic 718, which fair value is based on the closing market price of our common stock on the date of grant for RSUs, RSAs and PSUs. The amounts shown include PSU awards (including focal PSU awards, AIP PSU awards and new hire PSU awards), the value of which are calculated based on achievement at target as follows: for fiscal year 2026 PSUs: $7,875,481 (Mr. Hurlston), $2,684,770 (Mr. Ali), $1,789,925 (Mr. Retort), $2,684,770 (Mr. Yuen) and $1,372,229 (Mr. Kim); for fiscal year 2025 PSUs, $14,844,122 (Mr. Hurlston), $2,321,069 (Mr. Ali), $2,739,426 (Mr. Retort), $2,453,754 (Mr. Yuen) and $837,955 (Mr. Kim); for fiscal year 2024 PSUs, $2,093,218 (Mr. Ali), $2,480,900 (Mr. Retort), $2,220,371 (Mr. Yuen) and $860,199 (Mr. Kim). Assuming the highest level of performance is achieved under the applicable performance measures for PSUs (including focal PSU awards, AIP PSU awards and new hire PSU awards), the maximum possible value of the PSUs using the fair value of our common stock on the date that such awards were granted for accounting purposes is: for fiscal year 2026 PSUs: $15,750,962 (Mr. Hurlston), $5,369,540 (Mr. Ali), $3,579,850 (Mr. Retort), $5,369,540 (Mr. Yuen), and $2,744,458 (Mr. Kim); for fiscal year 2025 PSUs, $29,688,243 (Mr. Hurlston), $4,126,056 (Mr. Ali), $4,905,422 (Mr. Retort), $4,387,706 (Mr. Yuen) and $1,559,917 (Mr. Kim); for fiscal year 2024 PSUs, $2,093,218 (Mr. Ali), $2,480,900 (Mr. Retort), $2,220,371 (Mr. Yuen) and $860,199 (Mr. Kim). For fiscal year 2026, the amounts in this column also include the incremental fair value resulting from modification of our Fiscal Year 2024 and Fiscal Year 2025 PSU awards which were subsequently modified in fiscal year 2026, each computed in accordance with the provisions of FASB ASC Topic 718. See “Achievement and Vesting of Fiscal Year 2024 PSUs” in the Compensation & Discussion Analysis above and “Fiscal Year 2025 Long-Term Incentive Plan – Fiscal Year 2025 Long-Term Incentive Structure” in the Compensation & Discussion Analysis of our 2025 Proxy Statement. | | (3) Non-Equity Incentive Plan Compensation for fiscal years 2026, 2025 or 2024 was paid pursuant to the Lumentum Annual Incentive Plan (“AIP”). For fiscal year 2026, the Non-Equity Incentive Plan Compensation reflects the cash payout for fiscal year 2026. For fiscal year 2025, the Non-Equity Incentive Plan Compensation reflects the cash payout for fiscal year 2025, which reflects the AIP attainment for fiscal year 2025 in excess of 100%, as well as the payout to Mr. Hurlston as a new hire during fiscal year 2025. The 100% attainment of the AIP for fiscal year 2025, except for Mr. Hurlston, was paid in PSUs and the grant date fair value of such PSUs is reflected in the Stock Award column assuming achievement at target. Pursuant to Mr. Hurlston’s offer letter, his bonus under the AIP was paid in cash at the AIP achievement level for fiscal year 2025 with the amount pro-rated based on his service during fiscal year 2025. For fiscal year 2024, except for Mr. Kim, the Non-Equity Incentive Plan Compensation reflects the cash payout for the first half of fiscal year 2024. The second half payout for fiscal year 2024, except for Mr. Kim, was paid in PSUs and the grant date fair value of such PSUs is reflected in the Stock Award column assuming achievement at target. Pursuant to Mr. Kim’s offer letter, his bonus under the AIP was paid in cash at target for fiscal year 2024 with the amount pro-rated based on his service during fiscal year 2024. See footnote 6 below. | | (4) All amounts represent 401(k) employer matching contributions, imputed income for group term life insurance, HSA employer matching contributions and internet allowances. In fiscal year 2026, All Other Compensation: for Mr. Hurlston included $15,231 of 401(k) employer matching contributions and $6,213 of imputed income for group term life insurance; for Mr. Ali included $2,622 of imputed income for group term life insurance and $1,000 of HSA employer matching contributions; for Mr. Retort included $5,000 of 401(k) employer matching contributions and $15,326 of imputed income for group term life insurance; for Mr. Yuen included $5,000 of 401(k) employer matching contributions and $4,902 of imputed income for group term life insurance; and for Mr. Kim included $5,000 of 401(k) employer matching contributions, $4,386 of imputed income for group term life insurance and $600 of internet allowance. | | (5) Mr. Hurlston joined the Company in February 2025. For fiscal year 2025, the amount in the Bonus column represents a sign-on incentive bonus which, together with approximately $23,000,000 of the amounts in the Stock Awards column, represent incentives designed to compensate Mr. Hurlston for incentive opportunities forfeited by leaving his prior employer. |

  140. CEO Pay Ratio

    CEO Pay Ratio Our CEO pay ratio is calculated in accordance with Item 402(u) of Regulation S-K and provides a reasonable estimate of the ratio of our CEO’s annual total compensation to the median of the annual total compensation of all employees other than the CEO.

  141. CEO Pay Ratio

    | CEO annual total compensation as reported in Summary Compensation Table: | $15,392,731 | | Median employee annual total compensation: | $10,412 | | Ratio of our CEO to median employee: | 1,478 to 1 |

  142. CEO Pay Ratio

    We used the methodology, assumptions and estimates described below to determine the annual total compensation of the “median employee”:

  143. CEO Pay Ratio

    | • | We identified the median employee by reviewing the annual salary as of June 27, 2026 plus actual fiscal year 2026 Annual Incentive Plan (AIP) payout including actual commission payout during fiscal year 2026; | | • | We included employees working on a full-time and part-time basis, which includes employees integrated from recent acquisitions; | | • | Cost of living adjustments were not applied; | | • | For employees not paid in U.S. dollars, we applied a local currency-to-U.S. dollar exchange rate from Bloomberg on the last business day of the fiscal year; and | | • | After we identified the median employee, annual total compensation was then calculated by combining the following: |

  144. CEO Pay Ratio

    | – | Annual salary as of June 27, 2026; | | – | Actual fiscal year 2026 AIP payout; | | – | Actual commission payout during fiscal year 2026; and | | – | Other actual cash compensation during fiscal year 2026 (overtime, allowance, etc.). |
