September 27, 2019

Dear Lumentum Stockholders:

We are pleased and excited to invite you to attend the Annual Meeting of stockholders of Lumentum Holdings Inc. on November 14, 2019 at 8:00 am (Pacific Time), which will be a “virtual meeting” of stockholders, conducted via the Internet.

During fiscal 2019 we made significant progress towards our long-term strategic and financial goals. Fiscal 2019 net revenue was at a new high, exceeding $1.5 billion, and was up 25% relative to the prior year. For the first time, full year non-GAAP operating margin expanded to more than 20%.

During the past year, we believe we have added to, or extended, our market and technology leadership positions in each of our markets by introducing many highly differentiated new products and winning new design-ins with market leading customers. We believe we are well positioned in global markets that increasingly rely on our photonics products and technologies and benefit from durable long-term growth drivers. Continued strong growth in the amount of data flowing through the world’s optical networks and data centers drives increasing need for our communications products. We believe the market for our products used in 3D sensing will continue to expand in the coming years as 3D sensing enables computer vision applications which improve security and safety, as well as other new functionality, including virtual and augmented reality, in next-generation consumer electronic devices and automobiles. Higher required levels of precision, new materials, and factory and energy efficiency needs are causing manufacturers around the world to increasingly turn to laser-based approaches and the types of industrial lasers we supply.

In December 2018, we closed the acquisition of Oclaro, Inc., which has given us a first mover advantage in a transforming industry. We attained a leading position in telecom transmission, based on fundamental Indium Phosphide photonic integrated circuit technology. We believe this highly differentiated technology will be critical to our customers’ ability to scale to higher network bandwidths in the future. The acquisition has enabled us to transform our datacom business to a significantly more profitable model that is also based on highly differentiated photonic chip capabilities. Our datacom market focus has expanded to include 5G wireless and other high-volume applications. And finally, the acquisition has helped us improve our business model through the attainment of significant cost synergies on a more accelerated timeline than originally estimated and we are now increasing our annual synergy target to $100 million from our initial $60 million target, which we have already exceeded.

I believe these results and accomplishments both underscore the significant progress we made towards our strategic goals during fiscal 2019, and position us well for further revenue growth and margin in the future. These accomplishments, along with the growth catalysts we see across each of our major product lines, makes it is a very exciting time at Lumentum for all stakeholders. At Lumentum, we are releasing the power of light to create a brighter future.

In August 2019, we shared the news with great sadness that our Chairman, Marty Kaplan, passed away. Marty served as our Chairman since the inception of Lumentum with great passion and commitment. We will greatly miss his presence in the boardroom and as a friend and colleague.

Our virtual Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/LITE2019, where you will be able to listen to the meeting live, submit questions and vote online. We believe that a virtual stockholder meeting provides greater access to those who may want to attend and therefore have chosen this method for our Annual Meeting over an in-person meeting.

We are pleased to provide access to our proxy materials over the Internet under the U.S. Securities and Exchange Commission’s “notice and access” rules.

Details regarding how to attend the Annual Meeting online and the business to be conducted at the Annual Meeting are more fully described in the accompanying Notice of Annual Meeting and Proxy Statement.

Your vote is important and we hope you will vote as soon as possible, regardless of whether you plan to attend the meeting. You may vote by proxy over the Internet or by telephone, or, if you received paper copies of the proxy materials by mail, you may also vote by mail by following the instructions on the proxy card or voting instruction card.

Thank you for your ongoing support of and interest in Lumentum.

Sincerely,
 
Alan S. Lowe
President and Chief Executive Officer

Corporate Governance Highlights

The Board of Directors and management of Lumentum believe that good corporate governance is an important component in enhancing investor confidence in the Company and increasing stockholder value. The imperative to continue to develop and implement strong practices throughout our corporate governance structure is fundamental to our strategy to enhance performance by creating an environment that increases operational efficiency and ensures long-term productivity growth. Solid corporate governance practices also ensure alignment with stockholder interests by promoting fairness, transparency and accountability in business activities among employees, management and the Board.

Corporate Governance Highlights
●Majority voting for Directors ●Annual election of all Directors ●Independent Chair of the Board ●Independent Directors meet regularly without management present ●Audit, Compensation and Governance committees composed entirely of independent directors	●Engaged Board; each director attended at least 75% of the aggregate of all meetings of the board of directors and any committees on which he or she served during fiscal 2019 ●Significant share ownership guidelines for all executive officers and directors

PROPOSAL NO. 2 Non-binding, Advisory Vote to Approve Executive Compensation
The Board is asking stockholders to approve, on a non-binding, advisory basis, the compensation of the named executive officers as disclosed in this proxy statement.			Your Board of Directors recommends that you vote “FOR” this proposal.

PROXY SUMMARY

Executive Compensation Highlights

Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance. Consistent with this philosophy, we believe executives with higher levels of responsibility and a greater ability to influence Lumentum’s results should receive a greater percentage of their compensation as performance-based compensation. In fiscal 2019, we compensated our named executive officers using the following elements for total target direct compensation:

	Element and CEO % of Total Target Direct Compensation	Description and Metrics
	Base Salary	Fixed cash compensation to attract and retain highly-qualified executive talent.
	Annual Cash Incentive	Performance-based cash compensation to incentivize and reward achievement of near-term financial and business results. Performance measured: ●Operating income multiplied by a strategic modifier ●Full-year revenue
	Equity Incentives		Performance Stock Units (PSUs)
		●PSUs vesting over three years based on the achievement of fiscal 2019 revenue goal and acquisition-related synergies and continued service
			Restricted Stock Units (RSUs)
		●RSUs vesting over three years based on continued service

Robust Pay Governance Practices

We seek to adhere to best practices for compensation governance purposes. These provisions protect our stockholders’ interests, as follows:

What We Do

What We Don’t Do

●Strong Pay-for-Performance alignment ●Emphasis on long-term Company performance: Approximately 70% of our NEOs’ fiscal 2019 target compensation is in equity that vests over three years and with respect to the PSUs, only if we achieve the fiscal 2019 performance targets ●Minimal perquisites ●Robust Stock Ownership Guidelines for Directors, CEO and other Executive Officers ●Clawback Policy ●“Double-Trigger” change in control provisions ●Independent Compensation Committee ●Independent compensation advisor ●Annual risk review of our compensation programs

●No tax gross-ups upon a change in control ●No hedging or pledging

PROPOSAL NO. 3 Ratification of the Audit Committee’s Appointment of the Independent Registered Public Accounting Firm
The Board is asking stockholders to ratify the selection of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending June 27, 2020.			Your Board of Directors recommends that you vote “FOR” this proposal.

PROXY SUMMARY

LUMENTUM HOLDINGS INC.

PROXY STATEMENT FOR 2019 ANNUAL MEETING OF STOCKHOLDERS

To Be Held Virtually at 8:00am Pacific Time on Thursday, November 14, 2019

The accompanying proxy is solicited on behalf of the board of directors (the “board”) of Lumentum Holdings Inc. (“Lumentum”, “we”, “us” or the “Company”) for use at the Lumentum 2019 Annual Meeting of Stockholders (“Annual Meeting”) to be held virtually on Thursday, November 14, 2019 at 8:00am (Pacific Time), and any adjournment or postponement of the Annual Meeting. The virtual Annual Meeting can be accessed by visiting www.virtualshareholdermeeting.com/LITE2019, where you will be able to listen to the meeting live, submit questions and vote online. The Notice of Internet Availability of Proxy Materials and this proxy statement for the Annual Meeting (“Proxy Statement”) and the accompanying form of proxy were first distributed and made available on the Internet to stockholders on or about September 27, 2019. Lumentum’s annual report on Form 10-K for the fiscal year ended June 29, 2019, filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 27, 2019 (“Annual Report”), will be available with this Proxy Statement by following the instructions in the Notice of Internet Availability of Proxy Materials.

Internet Availability of Proxy Materials

In accordance with SEC rules, we are using the Internet as our primary means of furnishing proxy materials to stockholders. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send these stockholders a Notice of Internet Availability of Proxy Materials with instructions for accessing the proxy materials, including our Proxy Statement and Annual Report, and voting via the Internet. The Notice of Internet Availability of Proxy Materials also provides information on how stockholders may obtain paper copies of our proxy materials if they so choose. We believe this process makes the proxy distribution process more efficient and less costly and helps conserve natural resources.

General Information about the Annual Meeting

The information provided in the “question and answer” format below is for your convenience only and is merely a summary of the information contained in this Proxy Statement. You should read this entire Proxy Statement carefully. Information contained on, or that can be accessed through, our website is not intended to be incorporated by reference into this Proxy Statement and references to our website address in this Proxy Statement are inactive textual references only.

What matters am I voting on?

You will be voting on:

● the election of seven directors, all of whom are currently serving on our board of directors, to serve until our 2020 annual meeting of stockholders and until their successors are duly elected and qualified;

● the approval, on a non-binding, advisory basis, of the compensation of our named executive officers;

● the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending June 27, 2020; and

● any other business as may properly come before the Annual Meeting.

How does the board of directors recommend I vote on these proposals?

Our board of directors recommends a vote:

● “FOR” the election of Harold L. Covert, Penelope A. Herscher, Julia S. Johnson, Brian J. Lillie, Alan S. Lowe, Ian S. Small and Samuel F. Thomas as directors of the Company;

● “FOR” the approval of a non-binding, advisory vote on the compensation of our named executive officers; and

● “FOR” the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending June 27, 2020.

PROXY SUMMARY

Who is entitled to vote?

Holders of our common stock as of the close of business on September 20, 2019, the record date, may vote at the Annual Meeting. As of the record date, there were 77,208,702 shares of our common stock outstanding. In deciding all matters at the Annual Meeting, each stockholder will be entitled to one vote for each share of our common stock held by them on the record date. We do not have cumulative voting rights for the election of directors.

Stockholder of Record: Shares Registered in Your Name. If, on the record date, your shares were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are considered the stockholder of record with respect to those shares. As a stockholder of record, you may vote at the Annual Meeting or vote by telephone, by Internet, or by filling out and returning the proxy card.

Beneficial Owner: Shares Registered in the Name of a Broker or Nominee. If, on the record date, your shares were held on your behalf in a stock brokerage account or by a bank or other nominee, then you are considered the beneficial owner of those shares held in street name. Accordingly, the Notice of Internet Availability, Proxy Statement and any accompanying materials have been provided to your broker or nominee, who in turn provided the materials to you. As the beneficial owner, you have the right to direct your broker or nominee how to vote your shares by using the voting instruction card or by following their instructions for voting on the Internet or by telephone.

How many votes are needed for approval of each proposal?

● Proposal No. 1: Each director must be elected by the affirmative vote of a majority of the votes cast with respect to that director. This means that, to be elected, the number of votes cast for a director must exceed the number of votes cast against that director, with abstentions and broker non-votes not counted as votes cast for or against such director’s election.

● Proposal No. 2: The approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers requires the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. As a result, abstentions will have the same effect as votes against the proposal. Broker non-votes will have no effect on the outcome of this vote.

● Proposal No. 3: The ratification of the appointment of Deloitte & Touche LLP requires the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. As a result, abstentions will have the same effect as votes against the proposal. Brokers will have discretion to vote on this proposal.

What is a quorum?

A quorum is the minimum number of shares required to be present at the Annual Meeting for the Annual Meeting to be properly held under our amended and restated bylaws and Delaware law. The presence, in person or by proxy, of a majority of all issued and outstanding shares of our common stock entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting. Abstentions, withhold votes and broker non-votes are counted as shares present and entitled to vote for purposes of determining a quorum.

How do I vote?

If you are a stockholder of record, there are four ways to vote:

● via the virtual meeting website – any stockholder of record can attend the Annual Meeting by visiting www.virtualshareholdermeeting.com/LITE2019, where stockholders may vote and submit questions during the meeting. The Annual Meeting starts at 8:00am (Pacific Time) on Thursday, November 14, 2019. Please have your 16-digit control number to join the Annual Meeting. Instructions on how to attend and participate via the Internet, including how to demonstrate proof of stock ownership, are posted at www.proxyvote.com;

● by Internet at http://www.proxyvote.com, 24 hours a day, seven days a week, until 11:59 p.m. (Eastern Time) on November 13, 2019 (have your proxy card in hand when you visit the website);

● by toll-free telephone at 1-800-690-6903 (have your proxy card in hand when you call); or

● by completing and mailing your proxy card (if you received printed proxy materials).

Proxy cards submitted by mail must be received by November 13, 2019 to be voted at the Annual Meeting. Please note that the Internet and telephone voting facilities will close at 11:59 p.m. (Eastern Time) on November 13, 2019. Submitting your proxy, whether via Internet, by telephone or by mail, will not affect your right to vote via the virtual meeting website should you decide to attend the Annual Meeting. If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct your nominee on how to vote your shares.

All proxies will be voted in accordance with the instructions specified on the proxy. If you sign a physical proxy card and return it without instructions as to how your shares should be voted on a particular proposal at the Annual Meeting, your shares will be voted in accordance with the recommendations of our board of directors stated in this proxy.

Your vote is important. Whether or not you plan to attend the Annual Meeting, we urge you to vote by proxy to ensure that your vote is counted.

8 2019 Proxy Statement

PROXY SUMMARY

Can I change my vote?

Yes. If you are a stockholder of record, you can change your vote or revoke your proxy any time before the Annual Meeting by:

● entering a new vote by Internet or by telephone (only the later vote will count);

● returning a later-dated proxy card; or

● delivering to the Secretary of Lumentum Holdings Inc., by any means, a written notice stating that the proxy is revoked.

Additionally, you can change your vote or revoke your proxy by attending and voting at the Annual Meeting (although attendance at the Annual Meeting will not, by itself, revoke a proxy).

If you are a street name stockholder, your broker, bank or other nominee can provide you with instructions on how to change your vote.

How can I attend the Annual Meeting?

You are entitled to participate in the Annual Meeting if you were a holder of Lumentum shares as of the record date of September 20, 2019. You will be able to attend online and submit your questions during the meeting by visiting www.virtualshareholdermeeting.com/LITE2019. You also will be able to vote your shares electronically at the Annual Meeting. To participate, you will need the 16-digit control number included on your Notice of Internet Availability of Proxy Materials, on your proxy card or on the instructions that accompanied the proxy materials.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our board of directors. Alan Lowe, Wajid Ali and Judy Hamel have been designated as proxies by our board of directors. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors as described above. If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned, the proxy holders can vote the shares on the new Annual Meeting date as well, unless you have properly revoked your proxy instructions, as described above.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

In accordance with the rules of the SEC, we have elected to furnish our proxy materials, including this Proxy Statement and our Annual Report, primarily via the Internet. As a result, we are mailing to many of our stockholders a Notice of Internet Availability of Proxy Materials. All stockholders receiving the notice will have the ability to access the proxy materials over the Internet and request to receive a paper copy of the proxy materials by mail or e-mail. Instructions on how to access the proxy materials over the Internet or to request a paper or e-mail copy may be found in the Notice of Internet Availability of Proxy Materials. In addition, the notice contains instructions on how you may request access to proxy materials in printed form by mail or electronically on an ongoing basis.

How are proxies solicited for the Annual Meeting?

Our board of directors is soliciting proxies for use at the Annual Meeting. All expenses associated with this solicitation will be borne by us. We will reimburse brokers or other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker or other nominee holds shares of our common stock on your behalf. In addition to using the Internet, our directors, officers and employees may solicit proxies in person or by mailings, telephone, facsimile, or electronic transmission, for which they will not receive any additional compensation.

How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?

Brokerage firms and other intermediaries holding shares of our common stock in street name for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker will have discretion to vote your shares on our sole “routine” matter: the proposal to ratify the appointment of Deloitte & Touche LLP. Your broker will not have discretion to vote on the election of directors or the approval of the non-binding, advisory vote on the compensation of our named executive officers, each of which are “non-routine” matters, absent direction from you.

PROXY SUMMARY

Where can I find the voting results of the Annual Meeting?

We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Current Report on Form 8-K within four business days after the Annual Meeting, we will file a Current Report on Form 8-K to publish preliminary results and will provide the final results in an amendment to such Current Report on Form 8-K as soon as they become available.

I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we deliver a single copy of the Notice of Internet Availability of Proxy Materials and, if applicable, our proxy materials to multiple stockholders who share the same address unless we have received contrary instructions from one or more of the stockholders. This procedure reduces our printing costs, mailing costs, and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will deliver promptly a separate copy of the Notice of Internet Availability of Proxy Materials and, if applicable, our proxy materials, to any stockholder at a shared address to which we delivered a single copy of any of these materials. To receive a separate copy, or, if a stockholder is receiving multiple copies, to request that we only send a single copy of the Notice of Internet Availability of Proxy Materials and, if applicable, our proxy materials, such stockholder may contact our Investor Relations at 1(408) 546-5483 or by mail at the following address:

Lumentum Holdings Inc.
Attention: Investor Relations
400 North McCarthy Blvd.
Milpitas, California 95035

Stockholders who beneficially own shares of our common stock held in street name may contact their brokerage firm, bank, broker-dealer or other similar organization to request information about householding.

What is the deadline to propose actions for consideration at next year’s Annual Meeting of stockholders or to nominate individuals to serve as directors?

Stockholder Proposals

Stockholders may present proper proposals for inclusion in our Proxy Statement and for consideration at the next Annual Meeting of stockholders by submitting their proposals in writing to our Secretary in a timely manner. For a stockholder proposal to be considered for inclusion in our Proxy Statement for our 2020 Annual Meeting of stockholders, our Secretary must receive the written proposal at our principal executive offices no later than May 30, 2020. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 regarding the inclusion of stockholder proposals in company-sponsored proxy materials. Stockholder proposals should be addressed to:

Lumentum Holdings Inc.
Attention: Secretary
400 North McCarthy Blvd.
Milpitas, California 95035

Our amended and restated bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our Proxy Statement. Our amended and restated bylaws provide that the only business that may be conducted at an annual meeting is business that is (i) specified in our proxy materials with respect to such meeting, (ii) otherwise properly brought before the annual meeting by or at the direction of our board of directors, or (iii) properly brought before the annual meeting by a stockholder of record entitled to vote at the annual meeting who has delivered timely written notice to our Secretary, which notice must contain the information specified in our amended and restated bylaws. To be timely for our 2020 Annual Meeting of stockholders, our Secretary must receive the written notice at our principal executive offices:

● not earlier than August 16, 2020; and

● not later than the close of business on September 15, 2020.

10 2019 Proxy Statement

PROXY SUMMARY

In the event that we hold our 2020 Annual Meeting of stockholders more than 30 days before or more than 60 days after the one-year anniversary of the 2019 Annual Meeting, then notice of a stockholder proposal that is not intended to be included in our Proxy Statement must be received no later than the close of business on the later of the following two dates:

● the 90th day prior to such annual meeting; or

● the 10th day following the day on which public announcement of the date of such annual meeting is first made.

If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at such annual meeting.

CORPORATE GOVERNANCE

Our business affairs are managed under the direction of our board of directors, which is currently composed of seven (7) members. In August 2019, our Chairman since the inception of Lumentum, Marty Kaplan, passed away. Mr. Kaplan had served on our Board as Chairman and as Chair of the Governance Committee since our separation from Viavi (formerly JDS Uniphase) in 2015, and prior to that had served on the board of JDSU since 1997. We will greatly miss Mr. Kaplan’s presence in the boardroom and as a friend and colleague.

Director Independence

Our board of directors consists of seven members. Our board of directors consists of a majority of independent directors and committees of our board of directors consist solely of independent directors, as required by NASDAQ listing standards. Our board of directors has determined that the following directors are independent under the NASDAQ listing standards: Harold L. Covert, Penelope A. Herscher, Julia S. Johnson, Brian J. Lillie, Ian S. Small and Samuel F. Thomas.

Board Leadership Structure

Our board of directors has determined that it is in the best interests of the Company to maintain the board chairperson and chief executive officer positions separately. The board believes that having an outside, independent director serve as chairperson is the most appropriate leadership structure, as this enhances its independent oversight of management and the Company’s strategic planning, reinforces the board of director’s ability to exercise its independent judgment to represent stockholder interests, and strengthens the objectivity and integrity of the board. Moreover, we believe an independent chairperson can more effectively lead the board in objectively evaluating the performance of management, including the performance of the chief executive officer, and guide it through appropriate board governance processes. In August 2019, Ms. Herscher was elected Board Chair.

Board Oversight of Risk

We take a comprehensive approach to risk management. We believe risk can arise in every decision and action taken by the Company, whether strategic or operational. We therefore seek to include risk management principles in all of our management processes and in the responsibilities of our employees at every level. Our comprehensive approach is reflected in the reporting processes by which our management provides timely and comprehensive information to the board of directors to support the board of directors’ role in oversight, approval and decision-making.

Management is responsible for the day-to-day supervision of risks the Company faces, while the board of directors, as a whole and through its committees, has the ultimate responsibility for the oversight of risk management. Senior management attends board of directors meetings, provides presentations on operations including significant risks, including privacy and cyber security, legal compliance and risks associated with the general economy and political climate, and is available to address any questions or concerns raised by the board of directors. Additionally, our committees assist the board of directors in fulfilling its oversight responsibilities in certain areas. Generally, the committee with subject matter expertise in a particular area is responsible for overseeing the management of risk in that area. For example, the Audit Committee coordinates the board of directors’ oversight of the Company’s internal controls over financial reporting and disclosure controls and procedures. Management regularly reports to the Audit Committee on these areas. Additionally, the Compensation Committee assists the board of directors in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs as well as succession planning for senior executives. The Governance Committee assists the board of directors in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, membership and structure, and corporate governance topics. When any of the committees receives a report related to material risk oversight, the chairman of the relevant committee reports on the discussion to the full board of directors.

Compensation Program Risk Assessment

In fiscal 2019, a team composed of senior members of our human resources, finance and legal departments and our compensation consultant, Semler Brossy, inventoried and reviewed elements of our compensation policies and practices. This team then reviewed these policies and practices with our management team in an effort to assess whether any of our policies or practices create risks that are reasonably likely to have a material adverse effect on the Company. This assessment included a review of the primary design features of our compensation policies and practices, the process for determining executive and employee compensation and consideration of features of our compensation program that help to mitigate risk. Management reviewed and discussed the results of this assessment with the Compensation Committee, which consulted with Semler Brossy. Based on this review, we believe that our compensation policies and practices, individually and in the aggregate, do not create risks that are reasonably likely to have a material adverse effect on the Company.

Board Committees and Meetings

During fiscal 2019, the board of directors held 12 meetings. The board of directors has three committees: an Audit Committee, Compensation Committee, and Governance Committee. The members of the committees during fiscal 2019 are identified below.

Each director attended at least 75% of the aggregate of all meetings of the board of directors and any committees on which he or she served during fiscal 2019 after becoming a member of the board of directors or after being appointed to a particular committee. The Company encourages, but does not require, the members of its board of directors to attend the Annual Meeting. All members of our board of directors who were directors at the time attended our 2018 Annual Meeting. We anticipate that all directors will attend the 2019 Annual Meeting.

Audit Committee

MEMBERS: Harold L. Covert (Chair) Brian J. Lillie Julia S. Johnson* MEETINGS: 12 *As of August 21, 2019, Ms. Johnson replaced Mr. Thomas as a member of the Audit Committee.

The Audit Committee is responsible for assisting the full board of directors in fulfilling its oversight responsibilities relative to: ●the Company’s financial statements; ●financial reporting practices; ●systems of internal accounting and financial control; ●internal audit function; ●annual independent audits of the Company’s financial statements; and ●such legal and ethics programs as may be established from time to time by management and the board of directors.

The Audit Committee has sole authority to retain, engage and compensate the independent auditor and oversees the independence of the independent auditor. In addition, the Audit Committee considers whether the Company’s independent auditors’ provision of non-audit services is compatible with maintaining the independence of the independent auditors. The Board has determined that all members of the Audit Committee are, and in the case of Mr. Thomas, was, during the time he served on the Audit Committee, “independent” as defined in the applicable rules and regulations of the SEC and NASDAQ. The board of directors has further determined that Harold L. Covert is an “audit committee financial expert” as defined by Item 407(d)(5) of Regulation S-K of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). A copy of the Audit Committee charter can be viewed at the Company’s website at www.lumentum.com.

Compensation Committee

MEMBERS: Samuel F. Thomas* (Chair) Brian J. Lillie* Ian S. Small* MEETINGS: 9 *As of August 21, 2019, Mr. Thomas replaced Ms. Herscher as Chair of the Compensation Committee, and Mr. Lillie replaced Ms. Johnson as a member of the Compensation Committee. Mr. Small joined the Compensation Committee on February 6, 2019, replacing Mr. Covert.

The Compensation Committee is responsible for: ●ensuring that the Company adopts and maintains responsible and competitive compensation programs for its employees, officers and directors consistent with the long-range interests of stockholders; ●the administration of the Company’s employee stock purchase plan and equity incentive plans; ●reviewing the Compensation Discussion and Analysis section contained in the Company’s Proxy Statement and preparing the Compensation Committee Report for inclusion in the Proxy Statement; and ●reviewing and considering the results of any advisory stockholder votes on executive compensation.

The Compensation Committee has the authority to engage the services of outside advisors, experts and others to provide assistance as needed. During fiscal 2019, the Compensation Committee engaged Semler Brossy, a national compensation consulting firm, to assist with the Compensation Committee’s analysis and review of the compensation of our executive officers. Semler Brossy attends all Compensation Committee meetings, works directly with the Compensation Committee Chair and Compensation Committee members, and sends all invoices, including descriptions of services rendered, to the Compensation Committee Chair for review and payment approval. Semler Brossy did not perform any work for the Company that was not in support of the Compensation Committee’s charter nor authorized by the Compensation Committee Chair during fiscal 2019. The Board has determined that all members of the Compensation Committee are, and in the case of Ms. Johnson, Ms. Herscher and Mr. Covert, were, during the time he or she served on the Compensation Committee, “independent” as that term is defined in the applicable rules and regulations of the SEC and NASDAQ. Each member of the Compensation Committee is a non-employee director under Rule 16b-3 promulgated under the Exchange Act. A copy of the Compensation Committee charter can be viewed at the Company’s website at www.lumentum.com. Additional information on the Compensation Committee’s processes and procedures for consideration of executive compensation are addressed in the section entitled “Compensation Discussion and Analysis – Compensation Practices.”

Governance Committee
MEMBERS: Penelope A. Herscher (Chair)* Brian J. Lillie Julia S. Johnson* MEETINGS: 6 *As of August 21, 2019, Ms. Herscher was appointed as Chair of the Governance Committee to fill Mr. Kaplan’s prior role, and Ms. Johnson was appointed to the Governance Committee.	The Governance Committee: ●serves as the Company’s nominating committee; ●oversees the Company’s corporate governance practices; and ●recommends to the board of directors the adoption of governance programs.

As provided in the bylaws of the Company and the charter of the Governance Committee, nominations for director may be made by the Governance Committee or by a stockholder of record entitled to vote. The Governance Committee will consider and make recommendations to the board of directors regarding any stockholder recommendations for candidates to serve on the board of directors. Stockholders wishing to recommend candidates for consideration by the Governance Committee may do so by writing to the Company’s Corporate Secretary at 400 North McCarthy Boulevard, Milpitas, California 95035. Such writing must provide the candidate’s name, biographical data and qualifications, a document indicating the candidate’s willingness to act if elected, and evidence of the nominating stockholder’s ownership of Company stock not less than 60 days nor more than 90 days prior to the first anniversary of the date of the preceding year’s annual meeting to assure time for meaningful consideration by the Governance Committee. Our amended and restated bylaws specify in greater detail the requirements as to the form and content of the stockholder’s notice. We recommend that any stockholder wishing to nominate a director review a copy of our amended and restated bylaws, which may be obtained by accessing our public filings on the SEC’s website at www.sec.gov. There are no differences in the manner in which the Governance Committee evaluates nominees for director based on whether the nominee is recommended by a stockholder. All members of the Governance Committee are, and in the case of Mr. Kaplan, was, during the time he served on the Governance Committee, “independent” as that term is defined in the applicable NASDAQ rules and regulations.

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. The Governance Committee intends to continue to evaluate candidates for election to the board of directors on the basis of the foregoing criteria. While we do not have a formal written policy regarding consideration of diversity in identifying candidates, as discussed above, diversity is one of the numerous criteria that the Governance Committee considers when reviewing potential candidates. 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.

The Governance Committee operates under a written charter setting forth the functions and responsibilities of the committee. A copy of the charter can be viewed at the Company’s website at www.lumentum.com.

Compensation Committee Interlocks and Insider Participation

Communications with the Board of Directors

Interested parties wishing to communicate with our board of directors or with an individual member or members of our board of directors may do so by writing to our board of directors or to the particular member or members of our board of directors, and mailing the correspondence to our General Counsel at Lumentum Holdings Inc., 400 North McCarthy Boulevard, Milpitas, California 95035. Each communication should set forth (i) the name and address of the stockholder, as it appears on our books, and if the shares of our common stock are held by a nominee, the name and address of the beneficial owner of such shares, and (ii) the number of shares of our common stock that are owned of record by the record holder and beneficially by the beneficial owner.

Our General Counsel, in consultation with appropriate members of our board of directors as necessary, will review all incoming communications and, if appropriate, all such communications will be forwarded to the appropriate member or members of our board of directors, or if none is specified, to the Chairman of our board of directors.

Corporate Governance Guidelines and Code of Business Conduct

Our board of directors has adopted Corporate Governance Guidelines that address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a Code of Business Conduct that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The full text of our Corporate Governance Guidelines and our Code of Business Conduct is posted on the Investors page under the Corporate Governance portion of our website at www.lumentum.com. We will post amendments to our Code of Business Conduct or waivers of our Code of Business Conduct for directors and executive officers on the same website.

Risk Management

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the company faces, while our board of directors, as a whole and assisted by its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself that the risk management processes designed and implemented by management are appropriate and functioning as designed.

Our board of directors believes that open communication between management and our board of directors is essential for effective risk management and oversight. Our board of directors meets with our Chief Executive Officer and other members of the senior management team at quarterly meetings of our board of directors, where, among other topics, they discuss strategy and risks facing the company, as well as such other items as they deem appropriate.

While our board of directors is ultimately responsible for risk oversight, our board committees assist our board of directors in fulfilling its oversight responsibilities in certain areas of risk. Our Audit Committee assists our board of directors in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting and disclosure controls and procedures, and legal and regulatory compliance, and discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. Our Audit Committee also reviews our major financial risk exposures and the steps management has taken to monitor and control these exposures. Our Audit Committee also monitors certain key risks on a regular basis throughout the fiscal year, such as regulatory risk, liquidity risk and cybersecurity risk. Our Governance Committee assists our board of directors in fulfilling its oversight responsibilities with respect to the management of risk associated with board organization, membership and structure, and corporate governance. Our Compensation Committee assesses risks created by the incentives inherent in our compensation policies. Finally, our full board of directors reviews strategic and operational risk in the context of reports from the management team, receives reports on all significant committee activities at each regular meeting, and evaluates the risks inherent in significant transactions.

PROPOSAL NO. 1 ELECTION OF DIRECTORS

Vote Required

Each director will be elected by the affirmative vote of a majority of the votes cast, meaning that the numbers of votes cast “FOR” a director nominee exceeds the number of votes cast “AGAINST” that nominee. This means that the number of votes cast for a director must exceed the number of votes cast against that director, with abstentions and broker non-votes not counted as votes cast for or against such director’s election.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE ELECTION
TO THE BOARD OF EACH OF THE NOMINEES NAMED ABOVE.

Director Compensation

The compensation program for our non-employee directors (“Outside Directors”) is designed to attract and retain high quality directors and to align director interests with those of our stockholders. The compensation program was developed and approved in 2015 in connection with our Separation, and amended in February 2019 upon recommendation by the Compensation Committee and approval by the board of directors, with input from Semler Brossy regarding competitive practices. The compensation of our Outside Directors is reviewed annually by the board of directors upon recommendation from the Compensation Committee, which review includes a market assessment and an analysis by Semler Brossy. As part of this analysis, Semler Brossy reviews non-employee director compensation trends and data from similarly situated companies. Prior to the amendment in February 2019, no substantive changes were made to our Outside Director compensation program. In February 2019, our board of directors, with input from Semler Brossy, approved changes to the Outside Director compensation program to (i) increase the Annual RSU Awards (as defined below) from a value equal to $175,000 to a value equal to $220,000 and (ii) increase the annual cash payment for the chairman of the Audit Committee from $25,000 to $30,000. The change to the Annual RSU Awards will take effect on the awards to be granted on the date of our Annual Meeting on November 14, 2019. The change to the annual cash payment for the chairman of the Audit Committee took effect upon approval in February 2019. These changes were made to bring our outside director compensation program in better alignment with our competitive market.

Our Outside Directors receive compensation in the form of equity granted under the terms of our 2015 Equity Incentive Plan (the “2015 Plan”) and cash, as described below:

Equity Awards

Initial Award. On the date of the first meeting of our board of directors or Compensation Committee occurring on or after the date on which the individual first became an Outside Director, such Outside Director is granted an initial award of restricted stock units (“RSUs”) with a value equal to $200,000 (the “Initial RSU Award”). The Initial RSU Award vests in three annual installments from the commencement of the individual’s service as an Outside Director, subject to continued service as a director through the applicable vesting date. If a director’s status changes from an employee director to an Outside Director, he or she does not receive an Initial RSU Award.

Annual Awards. On the date of each annual meeting of our stockholders, each Outside Director who has served on our board of directors for at least the preceding six months is granted an award of RSUs with a value equal to $220,000 (the “Annual RSU Award”). The Annual RSU Award vests upon the earlier of (i) the day prior to the next year’s annual meeting of stockholders or (ii) one year from grant, subject to continued service as a director through the applicable vesting date.

The number of shares subject to equity awards is calculated by dividing the value by the average volume weighted average trading price for the month preceding the grant date.

Retirement Provisions for Equity Awards. Upon retirement of an Outside Director, all unvested RSUs automatically vest in full. The treatment of unvested RSUs held by an Outside Director upon a change in control is determined by the terms of the 2015 Plan.

Cash Compensation

Annual Fee. Each Outside Director receives an annual cash retainer of $85,000 for serving on our board of directors (the “Annual Fee”), paid quarterly. In addition to the Annual Fee, the non-employee board chair receives an additional cash retainer of $60,000.

Committee Service. The chairpersons of the three standing committees of our board of directors receive the following annual cash retainers, paid quarterly:

Audit Committee	30,000	(1)
Compensation Committee	20,000
Governance Committee	15,000

20 2019 Proxy Statement

PROPOSAL NO. 2

ADVISORY VOTE TO APPROVE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and SEC rules, we are seeking the approval of the Company’s stockholders, on an advisory, non-binding basis, of the compensation of our named executive officers (“NEOs”) as disclosed in this Proxy Statement.

Our compensation program is designed to attract, retain and motivate employees and to serve the long-term interests of our stockholders. Our compensation program promotes performance-based compensation and has evolved to align compensation with recognized best practices and to address market realities.

The items below contain a few highlights from our compensation program:

● A significant portion of executive compensation is variable and tied to our financial and/ or share price performance. Mr. Lowe, our chief executive officer, received 91% of his total target direct compensation (consisting of base salary, annual incentive bonus and long-term equity awards) in fiscal 2019 through either incentive cash or equity (including performance-based equity awards at target), and the other NEOs received 83% of their total target pay through incentive cash or equity on average.

● Pay levels and practices are regularly reviewed against external market best practices. The Compensation Committee regularly reviews both pay levels and practices against the external market to ensure that our approach to compensation is consistent with current industry best practices, while also supporting our business strategy and objectives.

● Greater emphasis on performance-based pay in fiscal 2019. The Compensation Committee increased the weighting of performance-based executive pay in fiscal 2019 by increasing the percentage of performance-based equity awards to approximately 50% of each NEO’s annual long-term equity compensation. This step is intended to reinforce our commitment to align compensation with the competitive market and tie executive pay to Company performance.

● Long-term performance conditions added for next year. In August 2019 the Compensation Committee approved annual performance-based equity grants for fiscal 2020 with a three-year performance period. This is a change from our historical practice of granting performance-based equity grants with a one-year performance period, and is designed to put a greater emphasis on long-term performance.

We maintain the following policies to ensure sound compensation practices and corporate governance:

● Clawback Policy which provides for the recapture of awards in the event of a restatement caused by fraudulent or illegal conduct

● “Double-Trigger” for equity acceleration upon change in control

● Independent compensation committee

● Independent compensation advisor

● Annual risk review of our compensation programs

● No excessive perquisites to executive officers

● No tax gross-ups upon change in control

● No hedging or pledging of our securities by employees or directors

The Compensation Discussion and Analysis section of this Proxy Statement contains a detailed discussion of our compensation philosophy and the alignment of our NEOs compensation to our performance.

We are asking our stockholders to vote, on a non-binding, advisory basis to approve the compensation paid to our NEOs, as described in the Compensation Discussion and Analysis and the compensation table sections of this Proxy Statement. We currently hold our advisory vote to approve the compensation paid to our NEOs on an annual basis, and our next such vote will be at our 2020 Annual Meeting.

The board of directors recommends that stockholders vote “FOR” the following resolution:

“RESOLVED, that the Company’s stockholders approve, on an advisory basis, the compensation of the Company’s named executive officers, as disclosed in this Proxy Statement for the 2019 Annual Meeting of stockholders pursuant to the compensation disclosure rules of the SEC, including the Compensation Discussion and Analysis, the FY2019 Summary Compensation Table, and other related tables and disclosures.”

21

PROPOSAL NO. 2 ADVISORY VOTE TO APPROVE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Vote Required

The approval on a non-binding, advisory basis of the compensation of the NEOs requires the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote thereon. As a result, abstentions will have the same effect as votes against the proposal. Broker non-votes will have no effect on the outcome of this vote.

This “say on pay” vote is advisory and therefore not binding on the Company, the board of directors or the Compensation Committee. However, the board of directors and the Compensation Committee value the opinions of our stockholders and will take into account the outcome of this vote in considering future compensation arrangements.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE APPROVAL, ON A NON-BINDING, ADVISORY
BASIS, OF THE COMPENSATION OF THE COMPANY’S NAMED EXECUTIVE OFFICERS.

PROPOSAL NO. 3

REPORT OF THE AUDIT COMMITTEE

The Audit Committee is a committee of the board of directors comprised solely of independent directors as required by the listing standards of the NASDAQ Stock Exchange and rules and regulations of the SEC. The Audit Committee operates under a written charter approved by the board of directors, which is available on our website at www.lumentum.com. The composition of the Audit Committee, the attributes of its members and the responsibilities of the Audit Committee, as reflected in its charter, are intended to be in accordance with applicable requirements for corporate audit committees. The Audit Committee reviews and assesses the adequacy of its charter and the Audit Committee’s performance on an annual basis.

With respect to the Company’s financial reporting process, the management of the Company is responsible for (1) establishing and maintaining internal controls and (2) preparing the Company’s consolidated financial statements. Our independent registered public accounting firm, Deloitte, is responsible for auditing these financial statements. It is the responsibility of the Audit Committee to oversee these activities. It is not the responsibility of the Audit Committee to prepare our financial statements, which are the fundamental responsibilities of management. In the performance of its oversight function, the Audit Committee has:

● reviewed and discussed the audited financial statements with management and Deloitte;

● discussed with Deloitte the matters required to be discussed by Auditing Standard No. 1301; and

● received the written disclosures and the letter from Deloitte required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the Audit Committee concerning independence, and has discussed with Deloitte its independence.

Based on the Audit Committee’s review and discussions with management and Deloitte, the Audit Committee recommended to the board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 29, 2019 for filing with the Securities and Exchange Commission.

Respectfully submitted by the members of the Audit Committee of the board of directors:

Harold L. Covert (Chair)

Executive Compensation Highlights

● Increases to Target Executive Compensation due to Strong Fiscal 2018 Performance and Increased Scale. The Compensation Committee increased total target direct compensation for each of our NEOs in recognition of strong financial performance in fiscal 2018 and the additional responsibilities each NEO assumed related to merger integration for the Oclaro merger. In addition, each NEO’s total target direct compensation was adjusted to reflect the post-acquisition scale of the Company, with revenue approximately 40% higher than pre-acquisition levels.

● Near Target Payout of Annual Cash Incentive Program for Fiscal 2019. The fiscal 2019 annual cash incentive plan was based on revenue and operating income. Due to solid financial and operational performance relating to these metrics during fiscal 2019, our NEOs received payouts under our fiscal 2019 annual cash incentive plan at 99.6% of target.

● Continued Use of Strategic Modifier in Annual Cash Incentive Plan for Fiscal 2019. As the Compensation Committee believes that focusing on specific operational objectives is important in measuring the Company’s annual performance, the Compensation Committee continued to use a strategic modifier with our annual cash incentive plan, similar to what was introduced in fiscal 2017 and used in fiscal 2018. The Compensation Committee may decrease or increase cash incentive pay as a result of performance on defined strategic measures by up to 20%.

● Increased Use of PSUs for Fiscal 2019. Our Compensation Committee increased the proportion of equity awarded in performance-based awards (“PSUs”) for the fiscal 2019 executive compensation program. The PSUs made up approximately one-half of the NEO’s annual equity award for fiscal 2019 compared to one-third of the NEO’s annual equity award for fiscal 2018.

● Long-term performance conditions added for next year. In August 2019 the Compensation Committee approved a modification to the annual equity grants for fiscal 2020 to put more emphasis on long-term performance by introducing a new 3-year measure in the performance-based equity for a portion of the awards.

Compensation Philosophy

Our executive compensation program is guided by our overarching philosophy of paying for demonstrable performance. Consistent with this philosophy, we have designed our executive compensation program to achieve the following primary objectives:

● Total compensation should attract, motivate and retain the talent necessary to achieve our business objectives in order 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 business and financial success.

● Our compensation practices should continue to evolve to align compensation with recognized best practices and to address current market realities.

28 2019 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

To further these objectives, we seek to adhere to best practice for compensation and corporate governance purposes. These provisions protect our stockholders’ interests, as follows:

What We Do

What We Don’t Do

●Pay for Performance: 91% of our CEO’s and 80% of our other NEOs’ fiscal 2019 target compensation was subject to Lumentum’s financial or market performance ●Emphasize Long-Term Company Performance: Approximately 70% of our NEOs’ fiscal 2019 target compensation is in equity that vests over three years ●Minimal perquisites ●Maintain Stock Ownership Guidelines: 5x salary for our CEO and 2x for other NEOs ●Maintain a Clawback Policy: Provides for the recapture of awards in the event of a restatement caused by fraudulent or illegal conduct ●Require “Double-Trigger” for equity acceleration in connection with a change in control ●Employ an independent compensation committee ●Engage an independent compensation advisor ●Conduct an annual risk review of our compensation programs

●No tax gross-ups upon a change in control ●No hedging or pledging of Lumentum securities by employees or directors

Elements of Our Fiscal 2019 Compensation Program

Our fiscal 2019 compensation program for our NEOs primarily consisted of salary, annual cash incentive, and equity awards according to the following structure:

Compensation Decision Processes

The Compensation Committee administers and determines the parameters of the executive compensation program with input from Semler Brossy, as well as our management. In addition, we value the positive endorsement by our stockholders of our pay practices. As we assessed our compensation programs in fiscal 2019, we were mindful of the strong support our stockholders expressed around our executive officer pay programs.

Semler Brossy provides advice relating to our compensation peer group selection as well as provides support and specific analysis with regard to compensation data and formulation of recommendations for executive compensation. Semler Brossy reports directly to our Compensation Committee and is independent from our management.

Our CEO and Senior Vice President of Human Resources present to the Compensation Committee performance reviews and compensation recommendations for our NEOs (other than our CEO). Our management team references the materials that Semler Brossy prepared for the Compensation Committee in developing NEO compensation recommendations for the Compensation Committee’s consideration.

29

COMPENSATION DISCUSSION AND ANALYSIS

The Compensation Committee approves all compensation for our NEOs (other than our CEO). The Compensation Committee reviews and recommends to the board of directors our CEO’s compensation, which is approved by the board of directors.

No member of the management team is present for the discussion or approval of his or her own compensation.

Peer Group

The Compensation Committee, with input from Semler Brossy, reviews the compensation practices at similarly situated companies that comprise our fiscal 2019 peer group. The characteristics and details around the fiscal 2019 peer group are listed below.

Characteristics of Peer Group	Peer Group Companies	Peer Group Financial Positioning
Characteristics: Companies similar in revenue, size, and business operations to Lumentum Primary Uses We reference peer group compensation practices when assessing and approving executive compensation in the following areas:   ●Performance and pay relationship ●NEO compensation levels ●Annual and long-term incentive plan design ●Independent director compensation ●Equity plan and share usage ●Change in control and severance ●Benefits and perquisites	Qorvo, Inc. Ciena Corporation Xilinx, Inc. Maxim Integrated Products Cypress Semiconductor Corp. F5 Networks, Inc. MKS Instruments, Inc. Coherent, Inc. FLIR Systems, Inc. Viasat, Inc. IPG Photonics Corporation Cree, Inc. NETGEAR, Inc. Finisar Corporation OSI Systems, Inc.	Lumentum and Peer Financial Positioning
		Chart above reflects Lumentum revenue on a pro forma basis.

In developing the fiscal 2019 peer group, the Compensation Committee considered the proforma revenue of the Company at the time of the acquisition which will not be fully recognized until fiscal 2020 reporting.

In addition, the Compensation Committee also reviews market data from the US Radford Survey for companies with comparable revenue size to assess the competitiveness of our executive compensation programs.

While the Compensation Committee’s review of competitive market data of the peer group companies and the survey data informs its decisions, the Committee also applies judgment in determining the pay levels of NEOs. Additional factors the Compensation Committee considers when making its compensation decisions include input from our management team, Company performance, individual performance and experience, each NEO’s role and/or retention and incentive objectives.

Fiscal 2019 Base Salary

Base salary represents the fixed portion of our NEOs’ compensation and is intended to attract and retain highly talented individuals. In determining base compensation levels, our Compensation Committee analyzes base salary information for similar positions and titles at companies in our compensation peer group and the survey data, and also considers the input from our management team as described above. In fiscal 2019, the Compensation Committee, after taking into account Company performance and the individual NEO’s performance, increased the base salaries of each of our NEOs as shown in the table below.

	Fiscal 2019 ($)(1)	Fiscal 2018 ($)	% Increase
Alan Lowe	800,000	750,000	6.7
Wajid Ali	500,000	—	—
Vincent Retort	485,000	465,000	4.3
Jason Reinhardt	430,000	430,000	—
Judy Hamel	400,000	380,000	5.3
Christopher Coldren	370,000	340,000	8.8

⁽¹⁾ Amounts in this table reflect annualized base salaries as of August 1, 2019. Actual salaries paid during these periods are described below under the section titled “— Summary Compensation Table.” For fiscal 2018, the base salary increases were effective October 15, 2017. For fiscal 2019, base salary increases were effective October 15, 2018.

30 2019 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

Annual Cash Incentive Plan

We operate an annual cash incentive plan (“CIP”) under our Executive Officer Performance-based Incentive Plan, which plan is intended to reward our NEOs for achieving annual financial goals.

Fiscal 2019

The Compensation Committee approved consolidated revenue and adjusted operating income percent dollars as the primary performance measures under the CIP for determining cash incentive amounts for our NEOs in fiscal 2019. These measures reflect the Company’s success in maintaining and growing the customer base while maintaining profitability, which the Compensation Committee believes are critical measures for Lumentum on an ongoing basis.

For fiscal 2019, the Compensation Committee determined that an aggregate bonus pool would be created under the CIP if we achieved positive operating income. If we achieved positive operating income for fiscal 2019, then the funding of the CIP would be based on our achievements as follows: 80% is measured on adjusted operating income dollars and 20% is measured on revenue. These performance measures were set at the beginning of each half of our fiscal year, with the first half measures based upon our annual operating plan, and the second half measures based upon our annual operating plan and forecast for the remainder of the fiscal year. Both operating income and revenue are measured in two six-month periods. For Mr. Reinhardt, the funding as it relates to his assigned bonus opportunity in fiscal 2019 would be reduced (but not increased) based on our achievement under the same bonus scheme as other participants described above (weighted approximately 50%) and revenue (weighted approximately 50%). We believe a different weighting for Mr. Reinhardt, our top sales executive, was appropriate to provide additional incentives for him to drive growth through sales.

The Compensation Committee also continued to use a strategic measure to the CIP for fiscal 2019 that acts as a modifier to CIP payout. The Compensation Committee believed that focusing on specific operational objectives was important to measuring success and that these strategic measures would help drive improvements in operational execution. The Compensation Committee has the discretion to adjust payouts by up to 20% in either direction for achievement of the strategic modifier based on the Compensation Committee’s subjective assessment with management’s input of certain operational measures in our business during fiscal 2019. The modifier impacts adjusted operating income for the first half of the year separately from adjusted operating income for the second half of the year and full year revenue.

The chart below illustrates the general structure of the CIP for fiscal 2019.

		Operating Income $ 1st Half		Strategic Modifier (Quality & Execution) +/- 20% (measured on 1st half)
		Revenue 1st Half
Annual Incentives
		Operating Income $ 2nd Half		Strategic Modifier (Quality & Execution) +/- 20% (measured on 2nd half)
		Revenue 2nd Half

If the threshold performance is achieved, the CIP generally will fund with respect to any performance measure based on a linear interpolation between threshold performance (50% funding) and maximum performance (200% funding), with the exception of the flat range around target to help provide some flexibility as shown below.

Upon the acquisition of Oclaro in fiscal 2019, we set annual incentive targets by combining the operating plans of the two companies on a prorated basis for the period where the companies were combined.

1st Half FY19 Op. Income (% of target)	2nd Half FY19 Op. Income (% of target)	Payout
160% or more	141% or more	200%
95% - 105%	95% - 105%	100%
71%	59%	50%
Less than 71%	<59%	0%
1st Half FY19 Revenue (% of target)	2nd Half FY19 Revenue (% of target)	Payout
111% or more	131%	200%
98% - 102%	97.5% - 102.5%	100%
84%	69%	50%
Less than 84%	69%	0%

Fiscal 2019 Annual Cash Incentive Plan Target Bonus Opportunities

In approving each NEO’s fiscal 2019 target bonus opportunities under the CIP, the Compensation Committee considered each NEO’s role at Lumentum and competitive market data from the fiscal 2019 peer group and survey data.

	Fiscal 2019 CIP Target
	Target ($)	% of Salary (%)
Alan Lowe	800,000	100
Wajid Ali	400,000	80
Vincent Retort	388,000	80
Jason Reinhardt(1)	344,000	80
Judy Hamel	240,000	60
Christopher Coldren	222,000	60

⁽¹⁾ Mr. Reinhardt’s target bonus is based on two components: (i) 50% of 80% of his base salary for achievement of revenue target; and (ii) 50% of 80% of his base salary for achievement of the CIP targets.

Fiscal 2019 Annual Cash Incentive Plan Achievement

Following the end of fiscal 2019, the Compensation Committee reviewed the achievement of the performance measures under the CIP and determined that we achieved positive operating income and the following results for the primarily performance measures:

	Minimum ($)	Target ($)	Maximum ($)	Performance as % of Target (%)
1st Half Adjusting Operating Income – 40% weight	100M	161-178M	240M	99.7
1st Half Consolidated Revenue – 10% weight	500M	707-743M	950M	97.9
2nd Half Adjusted Operating Income – 40% weight	93M	149-165M	221M	100.0
2nd Half Consolidated Revenue – 10% weight	559M	790-830M	1061M	99.4

32 2019 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

For the first half of fiscal 2019, our first half operating income was $160.6M, resulting in funding at 99.7% of target for this metric, and our first half consolidated revenue was $698.1M, resulting in our cash incentive plan funding at 97.9% of target for this metric. For the second half of fiscal 2019, our operating income was $153.7M, resulting in funding at 100% of target for this metric, and our second half consolidated revenue was $786.8M, resulting in funding of 99.4% for this metric. The CIP funding was 99.6% of target for the full fiscal 2019. This result incorporates adjustment of the plan and outcomes to exclude revenue associated with business closures which were determined and communicated externally immediately following the closing of the acquisition of Oclaro. We did not apply a strategic modifier under the CIP for the first or second half of fiscal 2019 because we met our strategic operational goals. Total fiscal 2019 CIP payouts for our NEOs were as follows:

	Fiscal 2019 CIP Target		Fiscal 2019 CIP Payouts
	Target ($)	% of Salary (%)	Payout ($)		% of Salary (%)
Alan Lowe	800,000	100	796,704		99.6
Wajid Ali	400,000	80	250,000	(1)	50.0
Vincent Retort	388,000	80	386,401		79.7
Jason Reinhardt	344,000	80	337,473		78.5
Judy Hamel	240,000	60	239,011		59.8
Christopher Coldren	222,000	60	221,085		59.8

⁽¹⁾ Mr. Ali was guaranteed a minimum CIP Payout for the 2nd half of fiscal 2019 of $250,000 pursuant to the terms of his offer letter.

Equity Incentive Awards

We use annual equity awards to deliver long-term incentive compensation opportunities to our NEOs and one-time equity awards to address special situations as they may arise from time to time, such as in connection with promotions to provide an additional retention incentive or to reward for extraordinary contributions. Our equity incentive awards are intended to align the interests of our NEOs with those of our stockholders. Equity awards are generally subject to vesting restrictions to encourage retention. To determine the size of annual equity awards for our NEOs, the Compensation Committee reviews each executive’s role, performance, and current competitive market information from both the compensation peer group and survey data and exercises its judgment to approve equity awards for our NEOs in amounts and on terms that the Compensation Committee deems competitive and that incentivize achievement of the compensation objectives described above.

COMPENSATION DISCUSSION AND ANALYSIS

Annual Equity Awards

Approximately 50% of each NEO’s annual equity award in fiscal 2019 was comprised of PSUs, with the remaining percent subject to time-based vesting. This represents an increase from approximately 33% of each NEO’s annual equity award in the form of PSUs for fiscal 2018. The Compensation Committee believes that performance-based equity awards are an important step to further enhancing the link between the interests of our NEOs and stockholders as the NEOs would only receive value from the performance-based equity awards if we achieved the performance conditions. The Compensation Committee reviews annually the mix and structure of performance-based and time-based equity awards for our NEOs in order to balance the desire for maintaining stability across the executive team and providing incentives for growth.

Performance-Based Equity Award

The fiscal 2019 PSUs granted to our NEOs are eligible to vest based on our achievements in consolidated revenue during fiscal 2019 as set forth in the table below. PSUs are also subject to a modifier based on achievement of acquisition-related synergies. This modifier is based on objective criteria established by the Compensation Committee and aligned with publicly-disclosed targets. The Committee has the discretion to adjust payouts by up to 20% in either direction for achievement of the strategic modifier based on the Compensation Committee’s subjective assessment with management’s input of certain operational measures in our business during fiscal 2019. This synergies modifier is in place for fiscal 2019 to encourage NEOs to achieve specific acquisition-related objectives, and has been removed for fiscal 2020 PSUs.

Any achieved portion of the fiscal 2019 PSUs vests over three years as to 1/3 on the date of achievement and quarterly thereafter subject to the NEO’s continued service.

Consolidated Revenue	Achievement Percentage*
$1.64B	200%
$1.49B	100%
$1.33B	50%
Less than $1.33B	0%

* If fiscal 2019 revenue achievement is between the two bands in the left column, then the achievement percentage is determined based on a linear interpolation.

The Compensation Committee selected consolidated revenue as the financial performance metric in an effort to provide additional incentives for our NEOs to drive top-line growth in our business. We believed the achievement levels in the table above were aggressive and would only be attained through diligent effort and leadership by our executive team.

Following the end of fiscal 2019, we determined that we achieved revenue of $1.46B, resulting in an achievement percentage of 88.96%. This result incorporates an adjustment of the plan to exclude revenue associated with closed businesses following the acquisition of Oclaro. The Compensation Committee applied a modifier to increase the achievement percentage by 10% for achievement of synergies above target, resulting in achievement of 98.96%.

Time-Based Equity Award

The fiscal 2019 time-based equity awards granted to our NEOs vest over three years as to 1/3 on the anniversary of the grant date and 1/12 quarterly thereafter subject to the NEO’s continued service.

Annual equity awards granted to our NEOs during fiscal 2019 are set forth in the table below on page 37. Except for certain acquisition-related awards to two NEOs as noted in the footnotes, equity grant levels were awarded to reflect strong performance for the fiscal year, taking into account the factors stated above.

Sign-on Bonus

Pursuant to his offer letter, Mr. Ali received a cash sign-on bonus of $1,000,000 in connection with his commencement of employment, subject to repayment of 100% of the sign-on bonus in the event that his employment is terminated by the Company for Cause (as defined in the Company’s 2015 Change in Control and Severance Benefits Plan, as amended (the “Change in Control Plan”)) or by Mr. Ali voluntarily within the first year of his employment, and subject to repayment of 50% of the sign-on bonus on a pro-rated basis over the number of months that he is employed in the event that his employment is terminated by the Company for Cause or by Mr. Ali voluntarily after the first year of his employment but before the second year of his employment. The Compensation Committee provided this bonus to Mr. Ali in order to recruit him to our Company.

Employment Agreement with Mr. Lowe

Lumentum entered into an employment agreement with Alan Lowe in August 2015. The employment agreement had an initial term of three years and will automatically renew for one year terms unless either party provides written notice of non-renewal at least 90 days prior to the end of the term. The employment agreement generally provides Mr. Lowe an annual base salary, an annual target bonus, and equity awards. The agreement makes Mr. Lowe eligible to participate in the employee benefit plans maintained by Lumentum or Lumentum Operations LLC, its subsidiary, and generally applicable to the senior executives of the Company. The employment agreement also provides Mr. Lowe lump sum cash payments and vesting acceleration of outstanding Lumentum equity awards under certain terminations of his employment. For additional information concerning Mr. Lowe’s change of control benefits, see “Payments Upon a Termination or Change of Control”.

COMPENSATION DISCUSSION AND ANALYSIS

Stock Ownership Guidelines

Our stock ownership guidelines require all executive officers and directors maintain a significant equity investment in Lumentum based upon a multiple of his or her base salary or annual cash retainer, respectively. The Compensation Committee approved an increase in the ownership requirements for executive officers in February 2019 to 2 times base salary, compared to 1 times base salary previously, and for the CEO to 5 times base salary, compared to 3 times base salary previously.

Title	Ownership Requirement
CEO	5x base salary
All Other Executive Officers	2x base salary
Directors	3x annual cash retainer

Shares owned outright and unvested and vested restricted stock and restricted stock units and any stock options exercisable within 60 days count toward the ownership requirements. These ownership levels must be attained within five years from the date of initial election or appointment to the board of directors, in the case of non-employee directors, or within five years following the appointment of executive officers. At the time the Compensation Committee reviewed the policy in August 2019, all directors and executive officers were in compliance or on track to achieve compliance with the guidelines.

Clawback Policy

The Compensation Committee approved a clawback policy in August 2016 that allows our board of directors the discretion to recover cash incentive plan awards and performance-based equity awards that are earned based on financial results, if those results are restated within three years of being earned as a result of fraudulent or illegal conduct. The policy covers our executive officers.

Federal Income Tax Consequences

Internal Revenue Code Section 162(m) (“Section 162(m)”) limits the deductibility of compensation paid by most publicly held companies to certain of their executive officers to $1,000,000 per year. However, compensation that qualifies as “performance-based” under Section 162(m) that is paid in 2017 or payable pursuant to a “written binding contract” prior to November 2, 2017 and not subsequently modified may be excluded from the $1,000,000 limit. While the Compensation Committee considers the deductibility of compensation as a factor in making compensation decisions, the Compensation Committee retains the flexibility to provide compensation that is consistent with our goals for our executive compensation program even if such compensation is not fully tax deductible. The Compensation Committee may make decisions that result in compensation expense that is not fully deductible under Section 162(m) of the Code. Recent tax reform legislation expanded the number of individuals covered by Section 162(m) of the Code and eliminated the exception for “performance-based” compensation beginning in 2018, subject to certain exceptions for compensation payable pursuant to a “written binding contract” in effect on November 2, 2017 that has not been subsequently materially modified.

Compensation Committee Report

The Compensation Committee has reviewed the Compensation Discussion and Analysis section and discussed it with management. Based on its review and discussions with management, the committee recommended to our board of directors that the Compensation Discussion and Analysis be included in this Proxy Statement and incorporated by reference into our Annual Report on Form 10-K for the fiscal year ended June 29, 2019.

(1)	Actual salary earned during fiscal 2019, 2018, or 2017, 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 stock-based compensation accounting rule FASB ASC Topic 718, excluding the effect of estimated forfeitures. The assumptions used to calculate these amounts are set forth under “Note 17. Stock Based Compensation and Stock Plans” in our Annual Report on Form 10-K for the fiscal year ended June 29, 2019. As required by SEC rules, the amounts shown exclude the impact of estimated forfeitures related to service-based vesting conditions. The amounts shown include PSU awards which are calculated based on achievement at target. Assuming the highest level of performance is achieved under the applicable performance measures for the fiscal 2019 PSUs, the maximum possible value of the fiscal 2019 PSUs using the fair value of our common stock on the date that such awards were granted for accounting purposes is: $6,978,755 (Mr. Lowe), $935,210 (Mr. Coldren), $3,117,554 (Mr. Retort), $1,766,513 (Mr. Reinhardt), and $935,210 (Ms. Hamel). Mr. Ali was not awarded any PSUs in fiscal 2019.
(3)	The stock awards for Mr. Lowe includes a PSU granted in fiscal 2016 for 36,927 shares. The PSU was scheduled to vest based on Mr. Lowe’s continued service and the Company’s performance in fiscal 2016 and 2017 relative to revenue targets set by the Compensation Committee. The actual number of shares that vest range from 0% to 150% of the target amount for each vesting tranche. 18,463 shares of the PSU did not vest and were cancelled in fiscal 2016, and 18,464 shares of the PSU, with a value of $1,053,371, satisfied the performance-based vesting condition in fiscal 2017 due to achievement of performance measures. 50% of these fiscal 2017 shares vested on August 15, 2017 and 50% vested on August 15, 2018.
(4)	Non-Equity Incentive Plan Compensation for fiscal 2019, 2018, and 2017 was paid pursuant to the Lumentum Cash Incentive Plan. See “-Annual Cash Incentive Plan” for an additional discussion.
(5)	All amounts represent 401(k) matching and HSA employer matching contributions by Lumentum.
(6)	Mr. Ali joined the Company in February 2019. The amount in the “Bonus” column represents a one-time sign-on bonus paid to him pursuant to his offer letter and subject to repayment terms set forth in the “Sign-on Bonus” section above.

(3)	PSUs that vest based upon the Company’s performance in fiscal 2019 relative to a revenue target set by the Compensation Committee. The PSU share amounts and values in the table above are calculated based on achievement at target. Upon achievement, the PSUs vest 1/3 upon the first anniversary of the grant date and the remainder in equal quarterly installments for two years thereafter. The actual number of shares that vested was 98.86% based on achievement of performance targets of 88.96% plus an increase of 10% for a modifier based on achievement of strategic objectives approved by the Compensation Committee.
(4)	Time-based RSAs and RSUs that vest 1/3 of the awarded units on the first anniversary of the grant date and the remainder of the units in equal quarterly installments for two years thereafter.

Stock Vested in 2019

The following table sets forth information on vesting of equity awards during fiscal 2019 for each NEO. The table includes: (i) the number of shares received from the vesting of restricted stock awards (“RSAs”), RSUs and PSUs and (ii) the aggregate dollar value realized upon the vesting of such RSAs, RSUs and PSUs.

	Stock Awards
Name	Number of Shares Acquired on Vesting (#)	Value Realized on Vesting ($)(1)
Alan Lowe	137,201	7,279,200
Wajid Ali	—	—
Christopher Coldren	13,836	711,129
Vincent Retort	55,573	2,928,522
Jason Reinhardt	33,486	1,798,774
Judy Hamel	15,996	874,568

⁽¹⁾ Represents the amounts realized based on the product of the number of shares acquired and the closing price of our Common Stock on NASDAQ on the vesting date.

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.

CEO total compensation as reported in Summary Compensation Table:	$9,325,740
Median employee annual total compensation:	$23,939
Ratio of our CEO to median employee:	390 to 1

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

● We identified the median employee by reviewing the fiscal 2019 salary (or wages plus overtime and other compensation components, as applicable) and annual cash bonus paid to all employees worldwide excluding our CEO, who were employed on April 1, 2019.

● We included employees working on a full-time, part-time, or interim basis, as well as contractual employees (as determined by the legal framework in a particular jurisdiction for contractual status).

● We annualized the base salary, but not the cash incentive paid for the fiscal year, for any full-time employees who were hired in fiscal 2019 but did not work for us for the entire fiscal year.

● 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.

● Annual total compensation for the median employee was then calculated using the same methodology we use for calculating CEO pay as outlined in the Summary Compensation Table.

CEO Change in Control Benefits

If Mr. Lowe’s employment is terminated without “cause”, he resigns for “good reason,” (each as defined in his employment agreement) or his employment terminates due to death or disability, during a period between a potential change in control date and ending 18 months following the consummation of a change in control (the “Coverage Period”), Mr. Lowe will receive from the Company (subject to Mr. Lowe signing and not revoking a release of claims with Lumentum and the LLC that becomes effective in accordance with the agreement):

(i)	a lump sum cash payment of 200% of his base salary for the year in which his employment is terminated plus 200% of his target annual bonus for the year in which his employment was terminated,

(i)	a lump sum cash payment equal to 150% of his base salary for the year in which his employment is terminated,
(ii)	acceleration of any of Mr. Lowe’s outstanding Lumentum equity awards such that Mr. Lowe will be vested in the number of Lumentum equity awards that Mr. Lowe would have been vested in had Mr. Lowe remained continuously employed for an additional 12 months, and

2015 Change in Control Benefits Plan

In April 2015, the board of directors of Viavi approved the Lumentum 2015 Change in Control Benefits Plan (the “Lumentum CIC Plan”), which was last amended by the Lumentum Compensation Committee in May 2018. Pursuant to the plan, eligible executives, including the NEOs (except for the CEO), will receive cash payments, COBRA reimbursements, and accelerated vesting of options, restricted stock units and other securities under the following circumstances.

In the event an eligible executive’s employment is terminated without “cause” (as defined in the Lumentum CIC Plan) or the eligible executive resigns for “good reason” (as defined in the Lumentum CIC Plan), in either case, occurring outside the date beginning on the public announcement of an intent to consummate a change in control of Lumentum and ending 12 months following the consummation of the change in control, the eligible executive will be entitled to receive from the Company (subject to the executive signing and not revoking a release of claims that become effective in accordance with the Lumentum CIC Plan):

(i)	accelerated vesting of unvested Lumentum equity awards held at the time of termination as to the number of shares that otherwise would vest over the nine-month period following the termination date,
(ii)	a lump sum payment (less applicable tax and other withholdings) equal to nine months of base salary, and
(iii)	reimbursement of COBRA premiums for the lesser of 9 months or the maximum allowable COBRA period.

In the event of a qualifying termination (as defined below), each of the eligible executives will be entitled to receive:

(i)	accelerated vesting in full of any unvested equity awards held at the time of termination (including accelerated vesting of any performance-based awards at 100% of the target achievement level),
(ii)	a lump sum payment (less applicable tax and other withholdings) equal to two years’ base salary, and
(iii)	reimbursement of COBRA premiums for the lesser of 12 months or the maximum allowable COBRA period.

40 2019 Proxy Statement

COMPENSATION DISCUSSION AND ANALYSIS

A qualifying termination under the Lumentum CIC Plan is (i) any involuntary termination without cause or resignation for good reason during the period beginning upon the public announcement of an intent to consummate a change in control of Lumentum and ending 12 months following the consummation of the change in control, or (ii) any termination due to disability or death occurring within 12 months following a change in control of Lumentum.

A change in control of Lumentum includes the acquisition by any person of more than 50% of the fair market value or voting power of outstanding Lumentum voting stock, a merger of Lumentum unless the Lumentum stockholders retain more than 50% of the voting power of the securities of the surviving entity and the Lumentum directors constitute a majority of the surviving entity’s board of directors, or a sale of substantially all of the assets of Lumentum.

Eligible executives are those employed in the United States or Canada who are (i) the Chief Executive Officer, (ii) an Executive Vice President, (iii) a Senior Vice President, (iv) a Section 16 “Officer” within the meaning of 17 C.F.R. § 240.16a-1(f) or (v) designated in writing by the Chief Executive Officer as being an Eligible Executive, subject to subsequent review and ratification by the Compensation Committee at its discretion.

The Lumentum CIC Plan is administered by the Compensation Committee of our board of directors.

RELATED PERSON TRANSACTIONS

We describe below transactions and series of similar transactions, since the beginning of our last fiscal year, to which we were or are to be a participant, in which:

● the amounts involved exceeded or will exceed $120,000; and

● any of our directors, nominees for director, executive officers or holders of more than 5% of our outstanding capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest.

Other than as described below, there has not been, nor is there any currently proposed, transactions or series of similar transactions to which we have been or will be a party.

Other Relationships and Related Persons Transactions

Jeff von Richter, an employee of Lumentum since 2015 as a Supply Chain Manager, is the brother-in-law of Alan Lowe, our president and chief executive officer. For the fiscal year ended June 29, 2019, Mr. von Richter’s total compensation, including salary, bonus, 401(k) matching and equity awards during the fiscal year valued at the fair market value on the grant date, was approximately $262,076. Mr. von Richter is also eligible to participate in employee benefit plans generally available to our employees.

Policies and Procedures for Related Party Transactions

Our Audit Committee has the primary responsibility for reviewing and approving or ratifying related party transactions. We have a formal written policy providing that a related party transaction is any transaction between us and an executive officer, director, nominee for director, beneficial owner of more than 5% of any class of our capital stock, or any member of the immediate family of any of the foregoing persons, in which such party has a direct or indirect material interest and the aggregate amount involved exceeds $120,000. In reviewing any related party transaction, our Audit Committee is to consider the relevant facts and circumstances available to our Audit Committee, including, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances, and the extent of the related party’s interest in the transaction. Our Audit Committee has determined that certain transactions will be deemed to be pre-approved by our Audit Committee, including certain executive officer and director compensation, transactions with another company at which a related party’s only relationship is as a non-executive employee, director or beneficial owner of less than 10% of that company’s shares and the aggregate amount involved does not exceed the greater of $200,000 or 2% of the company’s total revenues, transactions where a related party’s interest arises solely from the ownership of our common stock and all holders of our common stock received the same benefit on a pro rata basis, and transactions available to all employees generally. If advance approval of a transaction is not feasible, the chair of our Audit Committee may approve the transaction and the transaction may be ratified by our Audit Committee in accordance with our formal written policy.

45

OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires that our executive officers and directors, and persons who own more than 10% of our common stock, file reports of ownership and changes of ownership with the SEC. Such directors, executive officers and 10% stockholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

SEC regulations require us to identify in this Proxy Statement anyone who filed a required report late during the most recent fiscal year. Based on our review of forms filed with the SEC, or written representations from reporting persons stating that they were not required to file these forms, we believe that during our fiscal year ended June 29, 2019, all Section 16(a) filing requirements were satisfied on a timely basis with the exception of Form 4s for Mr. Lowe, Mr. Coldren, Mr. Retort, Mr. Reinhardt and Ms. Hamel which were due on August 14, 2018, but were filed on August 24, 2018, and a Form 4 for Mr. Kaplan which was due on February 26, 2019 but was filed on February 27, 2019, all due to administrative error.

Fiscal 2019 Annual Report and SEC Filings

Our financial statements for our fiscal year ended June 29, 2019 are included in our Annual Report on Form 10-K, which we will make available to stockholders at the same time as this Proxy Statement. This Proxy Statement and our Annual Report are posted on our website at www.lumentum.com and are available from the SEC at its website at www.sec.gov. You may also obtain a copy of our Annual Report without charge by sending a written request to Lumentum Holdings Inc., Attention: Investor Relations, 400 North McCarthy Blvd, Milpitas, California 95035.

46 2019 Proxy Statement

APPENDIX A

Reconciliation of GAAP and Non-GAAP Financial Measures

The Compensation Discussion and Analysis (“CD&A”) of this proxy statement contains non-GAAP financial measures for gross margin and operating margin. Lumentum believes this non-GAAP financial information provides additional insight into the Company’s on-going performance and has therefore chosen to provide this information to investors for a more consistent basis of comparison and to help them evaluate the results of the Company’s on-going operations and enable more meaningful period to period comparisons. Specifically, the Company believes that providing this information allows investors to better understand the Company’s financial performance and, importantly, to evaluate the efficacy of the methodology and information used by management to evaluate and measure such operating performance. However, these measures may be different from non-GAAP measures used by other companies, limiting their usefulness for comparison purposes. The non-GAAP financial measures used in this proxy statement should not be considered in isolation from measures of financial performance prepared in accordance with GAAP. Investors are cautioned that there are material limitations associated with the use of non-GAAP financial measures as an analytical tool. In particular, many of the adjustments to our GAAP financial measures reflect the exclusion of items that are recurring and will be reflected in our financial results for the foreseeable future. Further, these non-GAAP financial measures may not be comparable to similarly titled measurements reported by other companies.

Non-GAAP gross margin and non-GAAP operating margin exclude (i) stock-based compensation, (ii) acquisition related costs, (iii) other charges comprised mainly of set-up costs of our Thailand facility, including costs of transferring product lines to Thailand, as well as inventory write-downs due to cancelled programs and other costs and contingencies unrelated to current and future operations, (iv) amortization of acquired developed technologies, and (v) workforce related charges such as severance, retention bonuses and employee relocation costs related to formal restructuring plans. The presentation of these and other similar items in Lumentum’s non-GAAP financial results should not be interpreted as implying that these items are non-recurring, infrequent or unusual.

A quantitative reconciliation between GAAP and non-GAAP financial data with respect to historical periods is included in the table below.

	Fiscal 2019		Fiscal 2018		Fiscal 2017
Gross Margin on GAAP basis	27.2	%	34.6	%	31.8	%
Stock-based compensation	1.0	%	1.0	%	0.7	%
Other charges related to non-recurring activities(b)	4.9	%	3.0	%	1.5	%
Amortization of acquired developed technologies	3.0	%	0.3	%	0.6	%
Restructuring and related charges	3.5	%	0.0	%	0.0	%
Adjusted Gross Margin	39.5	%	38.9	%	34.7	%
Income (loss) from operations on GAAP basis	(1.4	)%	11.2	%	4.8	%
Stock-based compensation	4.5	%	3.8	%	3.3	%
Oclaro acquisition costs	1.0	%	0.4	%	0.0	%
Other charges related to non-recurring activities(b)	5.4	%	3.6	%	2.5	%
Impairment charges	2.0	%	0	%	0	%
Amortization of fair value adjustments	3.5	%	0	%	0	%
Amortization of intangibles	3.5	%	0.3	%	0.7	%
