**PRELIMINARY PROXY STATEMENT - SUBJECT TO COMPLETION**

**MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.**

**100 Chelmsford Street**

**Lowell, MA 01851**

**PRELIMINARY PROXY STATEMENT**

**FOR THE 2023 ANNUAL MEETING OF STOCKHOLDERS**

**GENERAL INFORMATION CONCERNING PROXIES AND VOTING AT THE ANNUAL MEETING**<br>

**Why did I receive these proxy materials?**

We are providing these proxy materials in connection with the solicitation by the board of directors of MACOM Technology Solutions Holdings, Inc., a Delaware corporation (the "Company," "MACOM," "we," "us" or "our"), of proxies to be voted at our 2023 Annual Meeting of Stockholders (the "Annual Meeting") and at any adjournment or postponement of the Annual Meeting. In accordance with rules of the Securities and Exchange Commission (the "SEC"), on or about January , 2023, we sent a Notice of Internet Availability of Proxy Materials and provided access to our proxy materials over the Internet to the holders of record and beneficial owners of our common stock as of the close of business on January 5, 2023 (the "Record Date").

The Annual Meeting will be held at the Holiday Inn Express, 8 Independence Drive, Chelmsford, Massachusetts 01824, on Thursday, March 2, 2023 at 3:00 p.m. (Eastern Time).

**What information is included in this Proxy Statement?**

The information in this Proxy Statement relates to the proposals to be voted on at the Annual Meeting, the voting process, our board of directors and board committees, the compensation of current directors and our current named executive officers for fiscal year 2022 and other information.

**Who is entitled to vote?**

Holders of our common stock at the close of business on the Record Date are entitled to receive the Notice of Annual Meeting of Stockholders and vote at the Annual Meeting. As of the close of business on the Record Date, there were 70,733,235 shares of our common stock outstanding and entitled to vote.

**How many votes do I have?**

On any matter that is submitted to a vote of our stockholders, the holders of our common stock are entitled to one vote per share of common stock held by them. Holders of our common stock are not entitled to cumulative voting in the election of directors.

**What is the difference between holding shares as a stockholder of record and as a beneficial owner?**

Most stockholders hold their shares through a broker, trust, bank or other nominee rather than directly in their own names.

If, on the Record Date, your shares were registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC, then you are a stockholder of record. As a stockholder of record, you may vote in person at the Annual Meeting or vote by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote over the Internet, by telephone or by filling out and returning a proxy card to ensure your vote is counted.

If, on the Record Date, your shares were held in an account at a brokerage firm, trust, bank, dealer or other similar organization, then you are the beneficial owner of shares held in "street name" and these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Annual Meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the Annual Meeting unless you request and obtain a valid legal proxy or letter from your broker, trust, bank or other nominee.

------

**What am I voting on?**

We are asking you to vote on the following matters in connection with the Annual Meeting:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

1. The election of three Class II directors nominated by our board of directors and named in the accompanying proxy materials to serve until the 2026 annual meeting of stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

2. An advisory vote approving the compensation of our named executive officers for fiscal year 2022;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

3. Ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending September 29, 2023;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

4. Approval of an amendment to the Company's Fifth Amended and Restated Certificate of Incorporation to reflect Delaware law provisions allowing officer exculpation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

5. Such other business as may properly come before the Annual Meeting and any adjournment or postponement thereof.

**What are the Board's recommendation?**

**How do I vote?**

*Vote by Internet.* Stockholders of record may submit proxies over the Internet by following the instructions on the Notice of Internet Availability of Proxy Materials or, if printed copies of the proxy materials were requested, the instructions on the printed proxy card. Most beneficial stockholders may vote by accessing the website specified on the voting instruction forms provided by their brokers, trustees, banks or other nominees. Please check your voting instruction form for Internet voting availability.

*Vote by Telephone.* Stockholders of record may submit proxies using any touch-tone telephone from within the United States by following the instructions on the Notice of Internet Availability of Proxy Materials or, if printed copies of the proxy materials were requested, the instructions on the printed proxy card. Most beneficial owners may vote using any touch-tone telephone from within the United States by calling the number specified on the voting instruction forms provided by their brokers, trustees, banks or other nominees. Please check your voting instruction form for telephone voting availability.

*Vote by Mail.* Stockholders of record may submit proxies by mail by requesting printed proxy cards and completing, signing and dating the printed proxy cards and mailing them in the pre-addressed envelopes that will accompany the printed proxy materials. Beneficial owners may vote by completing, signing and dating the voting instruction forms provided by their brokers, trustees, banks or other nominees and mailing them in the pre-addressed envelopes accompanying the voting instruction forms.

If you are a stockholder of record and you return your signed proxy card but do not indicate your voting preferences, the persons named in the proxy card will vote the shares represented by that proxy as recommended by the board of directors. If you are a beneficial owner and you return your signed voting instruction form but do not indicate your voting preferences, please see "What are the voting requirements to elect directors and approve each of the other proposals described in this Proxy Statement?" and "What are 'broker non-votes' and how do they affect the proposals?" regarding whether your broker, trust, bank or other nominee may vote your uninstructed shares on a particular proposal.

*Vote in Person at the Annual Meeting.* All stockholders of record as of the close of business on the Record Date can vote in person at the Annual Meeting. You can also be represented by another person at the Annual Meeting by executing a proper proxy designating that person. If you are a beneficial owner, you must obtain a legal proxy or letter from your broker, trust, bank or other nominee and present it to the inspector of election with your ballot to be able to vote at the Annual Meeting. Even if you plan to attend the Annual Meeting, we recommend that you also vote either by telephone, by Internet or by mail so that

------

your vote will be counted if you decide not to attend. Due to the COVID-19 pandemic, we request that you RSVP by emailing our investor relations department at ir@macom.com if you plan to attend the Annual Meeting in person so that we may ensure we have adequate space for in-person attendees and we reserve the right to require that all in-person attendees comply with then-applicable federal, state and local guidelines, mandates or recommendations or facility requirements in an effort to promote the well-being of all that attend the Annual Meeting.

**What does it mean if I receive more than one set of materials?**

If you receive more than one set of materials, your shares are registered in more than one name or are registered in different accounts. In order to vote all of the shares you own, you must either sign and return all of the proxy cards or follow the instructions for any alternative voting procedures on each of the proxy cards or Notice of Internet Availability of Proxy Materials you receive.

**What can I do if I change my mind after I vote?**

If you are a stockholder of record, you may revoke your proxy at any time before it is exercised at the Annual Meeting by (a) delivering written notice, bearing a date later than the proxy, stating that the proxy is revoked to MACOM Technology Solutions Holdings, Inc., 100 Chelmsford Street, Lowell, Massachusetts 01851, Attn: Investor Relations Department, (b) submitting a later-dated proxy relating to the same shares by mail, telephone or the Internet prior to the vote at the Annual Meeting or (c) attending the Annual Meeting and voting in person. Stockholders of record may send a request for a new proxy card via e-mail to sendmaterial@proxyvote.com, or follow the instructions provided on the Notice of Internet Availability of Proxy Materials and proxy card to submit a new proxy by telephone or via the Internet. Stockholders of record may also request a new proxy card by calling 1-800-579-1639.

If you are a beneficial stockholder, you may revoke your proxy or change your vote only by following the separate instructions provided by your broker, trust, bank or other nominee.

**What constitutes a quorum at the Annual Meeting?**

Transaction of business at the Annual Meeting may occur only if a quorum is present. If a quorum is not present, it is expected that the Annual Meeting will be adjourned or postponed in order to permit additional time for soliciting and obtaining additional proxies or votes, and, at any subsequent reconvening of the Annual Meeting, all proxies will be voted in the same manner as such proxies would have been voted at the original convening of the Annual Meeting, except for any proxies that have been effectively revoked or withdrawn.

The presence at the Annual Meeting, in person or by proxy, of the holders of a majority of the total votes entitled to be cast constitutes a quorum. Abstentions, "withhold" votes and "broker non-votes" are counted as present and entitled to vote for purposes of determining a quorum.

**What are the voting requirements to elect directors and approve each of the other proposals described in this Proxy Statement?**

With respect to Proposal 1, the election of our directors, the Class II director nominees receiving the largest number of votes will be elected. Only votes "for" are counted in determining whether a plurality has been cast in favor of a director nominee. If you "withhold" authority to vote with respect to the election of some or all of the nominees, your shares will not be voted with respect to those nominees indicated. With respect to Proposals 2 and 3, the affirmative vote of a majority of the votes cast on the matter is required for the proposal to be approved. With respect to Proposal 4, the affirmative vote of a majority of the shares outstanding on the Record Date and entitled to vote on this proposal is required for the proposal to be approved. With respect to Proposals 1 and 2, abstentions and broker non-votes are not counted as votes in favor of or against any proposal or director nominee. With respect to Proposal 3, abstentions are not counted as votes in favor of or against the proposal, and we do not expect broker non-votes on the proposal. With respect to Proposal 4, abstentions and broker non-votes will have the same effect as votes against the proposal.

**What are "broker non-votes" and how do they affect the proposals?**

A broker non-vote occurs when a nominee holding shares for a beneficial owner does not vote the shares on a proposal because the nominee does not have discretionary voting power for a particular item and has not received instructions from the beneficial owner regarding voting. Brokers who hold shares for the accounts of their clients have discretionary authority to vote shares if specific instructions are not given with respect to routine matters. Although the determination of whether a nominee will have discretionary voting power for a particular item is typically determined only after proxy materials are filed with the SEC, we expect that the proposal on ratification of the appointment of our independent registered public accounting firm (Proposal 3)

------

will be a routine matter and that the other proposals (Proposals 1, 2 and 4) will be non-routine matters. Accordingly, if your shares are held by a broker on your behalf and you do not instruct the broker as to how to vote your shares, your broker will be entitled to exercise discretion to vote your shares only on the proposal to ratify the appointment of our independent registered public accounting firm, but your broker may not exercise discretion to vote on the other proposals.

**What are the requirements for admission to the Annual Meeting?**

Only stockholders of record and persons holding proxies from stockholders of record may attend the Annual Meeting. If your shares are registered in your name, you must bring a valid form of photo identification, such as a valid driver's license or passport, to the Annual Meeting. If your shares are held in the name of a broker, trust, bank or other nominee, you must bring a legal proxy or letter from that broker, trust, bank or other nominee that confirms you are the beneficial owner of those shares and a valid form of photo identification. Attendance at the Annual Meeting without voting or revoking a previously submitted proxy in accordance with the voting procedures will not in and of itself revoke a proxy. Due to the COVID-19 pandemic, we request that you RSVP by emailing our investor relations department at ir@macom.com if you plan to attend the Annual Meeting in person so that we may ensure we have adequate space for in-person attendees and we reserve the right to require that all in-person attendees comply with then-applicable federal, state and local guidelines, mandates or recommendations or facility requirements in an effort to promote the well-being of all that attend the Annual Meeting.

**Who will pay for the cost of this proxy solicitation?**

We will bear the cost of the solicitation of proxies from our stockholders. In addition to solicitation by mail, our directors, officers and employees, without additional compensation, may solicit proxies from stockholders by telephone, letter, facsimile, email, in person or otherwise. Following the original circulation of the proxies and other soliciting materials, we will request brokers, trusts, banks or other nominees to forward copies of the proxy and other soliciting materials to persons for whom they hold shares of our common stock and to request authority for the exercise of proxies. In such cases, we, upon the request of the brokers, trusts, banks and other nominees, will reimburse such holders for their reasonable expenses.

**Why did I receive a one-page notice in the mail regarding the Internet availability of proxy materials instead of a full set of proxy materials?**

We have elected to provide access to our proxy materials over the Internet. Accordingly, we are sending a Notice of Internet Availability of Proxy Materials to stockholders of record as of the Record Date. Stockholders will have the ability to access the proxy materials on the website referred to in the Notice of Internet Availability of Proxy Materials, or to request to receive an electronic copy or printed set of the proxy materials. Instructions on how to access the proxy materials over the Internet or to request an electronic copy or printed copy may be found in the Notice of Internet Availability of Proxy Materials. In addition, stockholders may request to receive proxy materials in printed form by mail or electronically by email on an ongoing basis. We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of the Annual Meeting.

**When will we announce the results of the voting?**

Voting results will be announced by the filing of a Current Report on Form 8-K within four business days after the Annual Meeting. If final voting results are unavailable at that time, we will file an amended Current Report on Form 8-K within four business days of the day the final results become available.

**SOCIAL RESPONSIBILITY, ENVIRONMENTAL SUSTAINABILITY AND RELATED POLICIES**<br>

We endeavor to integrate environmental, social and corporate governance ("ESG") practices that we believe will create long-term economic value for our stockholders, employees, communities and other constituents. Our corporate governance program is discussed elsewhere in this Proxy Statement.

**ESG Program**

In fiscal year 2020, we commenced an in depth, multi-year, company-wide review of ESG-related matters and initiatives, with the goal of enhancing and/or creating additional policies, procedures, programs and practices aimed at continuous improvement in these areas. This review resulted in the establishment of our ESG steering committee as well as the publication of our annual ESG reports in July 2021 and 2022. Our ESG steering committee has responsibility for ESG matters globally, oversees alignment between our ESG efforts and our overarching business objectives and reports to the executive leadership and the nominating governance committee of our board of directors. Our ESG steering committee includes C-suite executives and senior leaders in Global Operations, Quality, Compliance, Human Resources, Legal, Finance, IT and Data Privacy and Investor Relations. We encourage our stockholders to review our 2022 ESG report in full. A summary of the matters contained in our 2022 ESG report are discussed below.

**COVID-19 Response**

We continued to prioritize ensuring the health and safety of our global workforce during the COVID-19 global pandemic, including by, among other things, facilitating, and for certain locations, requiring that certain employees work remotely. We also implemented extensive health screening and sanitation policies at our facilities to ensure the safety of all essential employees. In addition, we supported our workforce with advice and guidance on protecting their own health and the health of their families and, in certain locations, provided onsite COVID-19 testing and COVID-19 vaccination clinics. We will continue to prioritize the health and safety of our employees.

**Corporate Culture and Employee Engagement** 

We are committed to fostering a corporate culture that encourages and seeks the betterment of the Company and the communities in which we conduct business. We strive to foster a sense of community and well-being that encourages our employees to focus on both their and the Company's long-term success. We realize that continuous engagement with our employees in a transparent, collaborative manner that builds trust is vital to driving successful outcomes. Executive management regularly conducts town hall-style meetings with employees to address business operations, strategy, market conditions and other topics. This format encourages open dialogue and provides employees with an opportunity to ask questions and voice opinions and ideas.

We offer, among other things, competitive and balanced compensation programs commensurate with those of our peers and competitors, including, but not limited to, well-rounded healthcare, prescription drug and disability insurance benefits for our employees and their families, a 401(k) plan for our U.S.-based employees and similar retirement savings programs for certain of our non-U.S.-based employees with a matching contribution by the Company and an employee stock purchase plan. We

------

provide competitive paid time-off benefits, a parental leave program following the birth, adoption or fostering of a child and an employee assistance plan that provides professional support, access to special programs and certain resources to our employees experiencing personal-, work-, financial- or family-related issues.

We are passionate about developing and growing our talent. We devote substantial efforts to retaining, motivating and supporting our employees by providing tuition and professional development reimbursement and opportunities for internal growth and career advancement. Performance reviews are conducted at least annually for all employees, during which employees and managers address goals and discuss development opportunities, strengths and weaknesses. We have also historically maintained an internship program that supports the professional development of interns and our employees. Our compensation policies recognize and reward individual and collective contributions to our growth and success.

We recognize and respect the freedom of employees to exercise their lawful rights, free association and collective bargaining. Certain of our employees working outside of the United States are represented by works councils. We value the relationships that we have with not only those employees but their representation as well.

**Employee Health and Safety**

We employ more than 1,200 people worldwide and strive to provide each employee with a safe and healthy work environment. We have health and safety team members to support compliance requirements and also promote and encourage employees to maintain healthy and safe lifestyles. Our goal is to reduce the potential for injury or illness by maintaining safe working conditions, such as providing proper tools and training to all employees. Additionally, we offer resources to our employees to encourage healthy habits, such as health coaches, wellness incentives and a diabetes prevention program.

**Diversity, Equity, Inclusion and Belonging**

We continue to create a culture of diversity, equity, inclusion and belonging ("DEI&B") in the workplace in order to promote and effect change at the corporate and community levels. We support fostering a work environment where everyone has equal opportunities to learn and grow. Our DEI&B efforts are guided by the following principles: (i) diversity is the representation of different people in an organization; (ii) equity is ensuring that everyone has fair, just and equal opportunities at work; (iii) inclusion is ensuring that everyone has an equal opportunity to contribute to and influence every part and level of a workplace; and (iv) belonging is ensuring that everyone feels safe and welcome at work.

In addition, we seek to continuously reinforce our commitment to DEI&B through our policies, learning and development programs and opportunities, ongoing training and internal reporting mechanisms. For example, all of our employees are required to acknowledge receipt of the Company's Code of Business Conduct and Ethics (the "Code of Conduct") upon commencing employment and on an annual basis thereafter. The Code of Conduct sets out basic principles, guidelines and prohibitions to guide all employees, including with respect to equal employment opportunity, non-discrimination, anti-harassment, reporting suspected violations of the Code of Conduct and/or law and prohibitions on retaliation for complying with the Code of Conduct.

**Environmental Stewardship; Climate** 

Our commitment to conducting our business in an environmentally responsible and sustainable manner is aimed at protecting the environment, with a particular emphasis on energy and water usage and environmental quality, while providing an atmosphere for continuous business growth and development. We also expect a commitment to environmentally sustainable business practices from our suppliers and plan to seek to develop ways to reduce our climate footprint.

For instance, at our Lowell, Massachusetts corporate headquarters, we promote environmental and energy efficiency awareness and encourage practices such as powering down office equipment at the end of the day, water and material conservation and recycling paper waste. We also have minimized our corporate travel requirements through the use of virtual meeting technology, reduced our number of printers and copiers by switching to electronic media and reduced waste streams from our corporate cafeteria. In addition, our Lowell, Massachusetts headquarters building, which was constructed in 2018, includes, among other things, motion sensor lighting, motion sensor and low flow water faucets and refillable water stations, electric vehicle charging stations and energy efficient equipment upgrades. In fiscal year 2020, we initiated a long-term project to become more energy efficient and less dependent on the public power grid. Our project includes entering into an agreement with a third party energy service provider to install a state of the art CCHP plant at our Lowell, Massachusetts fabrication facility. The CCHP plant went online during October 2022 and is expected to reduce our consumption of energy while delivering sustainable, resilient energy for heating and cooling, which will help us to meet sustainability targets, improve energy efficiencies and achieve energy resilience at that facility and is expected to reduce our carbon emissions by up to 1,869 metric tons per year.

**Community Service and Philanthropy**

------

We take an active role in supporting the communities in which we operate by partnering with organizations to administer charitable contributions, provide community service and organize the donation of goods to assist local families and individuals in need. For instance, our charitable giving program further promotes community-level involvement through our donation of up to 5,000 annual company-funded, employee volunteer hours on approved charitable activities. We believe that our dedication to being a responsible corporate citizen has a direct and positive impact in the communities in which we operate and contributes to the strength of our reputation and our financial performance.

------

As of December 31, 2022, as a group, our board of directors possesses a broad range of experience and skills including:

![chart-5d966673dfe44c14a77.jpg](chart-5d966673dfe44c14a77.jpg)

------

**CORPORATE GOVERNANCE**<br>

**Board of Directors**

Our board of directors and its committees meet throughout the year on a set schedule, and also hold special meetings and act by written or electronic consent from time to time. During fiscal year 2022, including telephonic meetings, our board of directors held seven meetings, the audit committee held nine meetings, the compensation committee held five meetings and the nominating and governance committee held seven meetings. From time to time during fiscal year 2022, our directors who are "independent" according to the rules and regulations of the SEC and the listing requirements and rules of the Nasdaq Stock Market ("Nasdaq") also met separately in executive sessions at which only independent directors were present.

During fiscal year 2022, each member of the board of directors attended 75% or more of the aggregate number of meetings of the board and committees on which they served. We encourage, but do not require, our directors and nominees for director to attend our annual meeting of stockholders in person or telephonically. Five of our directors attended our 2022 annual meeting of stockholders held in March 2022.

**Director Independence**

Our board of directors has reviewed its composition, the composition of its committees and the independence of each member of our board of directors during fiscal year 2022. Based on information requested from and provided by each director concerning their background, employment and affiliates, our board of directors has determined that Messrs. Bland, Chung, Ribar, Ritchie and VanLunsen and Ms. Rosenband qualify as "independent" according to the rules and regulations of the SEC and the Nasdaq listing requirements and rules. As of January 6, 2023, according to the rules and regulations of the SEC and the listing requirements and rules of Nasdaq, Mr. Daly is not independent because he is one of our executive officers, Mr. Ocampo is not independent because he was one of our executive officers within the past three years, and Mrs. Ocampo is not independent because she is the spouse of a former executive officer within the past three years.

The listing requirements and rules of Nasdaq require that, subject to certain exemptions, the board of directors of a listed company be comprised of a majority of independent directors, that the compensation, nominating and governance and audit committees of such listed company be comprised solely of independent directors, that the compensation committee be comprised of at least two independent directors, and that the audit committee be comprised of at least three independent directors. As of January 6, 2023, the composition of our board of directors and its committees satisfied all such requirements.

**Board Leadership Structure**

While our board of directors does not currently have a policy as to whether the offices of Chairman of the board of directors and Chief Executive Officer should be separate, Mr. Ocampo currently serves as Chairman of the board of directors and Mr. Daly serves as our Chief Executive Officer. Our board of directors believes that maintaining the flexibility to make this determination allows it to ensure that the Company maintains a leadership structure that is, at any given time, the most appropriate for our Company and, as a result, our stockholders. The board of directors believes that its current leadership structure, with Mr. Ocampo serving as Chairman of the board of directors and Mr. Daly serving as Chief Executive Officer, is appropriate because it enables the board of directors as a whole to engage in oversight of management, promote communication between management and the board of directors and oversee governance matters and risk management activities, while leveraging the experience of Mr. Ocampo as our Chairman given his service as one of our directors since our inception and allowing Mr. Daly as our Chief Executive Officer to focus on his primary responsibility for the operational leadership and strategic direction of the Company. In addition, the board of directors benefits from the perspective and insights of Messrs. Ocampo and Daly as a result of their extensive experience in the semiconductor industry.

**Risk Oversight**

The board of directors oversees our risk management activities. The board of directors implements its risk oversight function both as a whole and through delegation to its committees. These committees meet regularly and report back to the full board of directors. The audit committee has primary oversight responsibility with respect to financial risks as well as oversight responsibility for our overall risk assessment and risk management policies and systems. The audit committee oversees our procedures for the receipt, retention and treatment of complaints relating to accounting and auditing matters and oversees our management of legal and regulatory compliance systems, including risks associated with information security and technology (including cybersecurity). The compensation committee oversees risks relating to our compensation plans and programs, including the evaluation of whether our compensation programs encourage excessive risk-taking. The compensation committee believes that we have no compensation programs that give rise to excessive risk-taking. The nominating and governance committee oversees risks associated with corporate governance and the composition of our board of directors, including the

------

independence of board members and ESG-related matters. Each committee reports on its activities to the full board of directors from time to time. This enables the board of directors and its committees to coordinate their respective risk oversight roles.

**Policy Against Hedging of Stock**

Our insider trading policy prohibits our directors, officers, employees and consultants from entering into certain forms of hedging or monetization transactions, such as zero-cost collars, prepaid variable forward sale contracts, equity swaps and exchange funds because such transactions allow an individual to continue to own the covered securities, but without the full risks and rewards of ownership. When that occurs, the individual may no longer have the same objectives as our other stockholders.

**Director Overboarding Guidelines**

The board of directors has instituted guidelines to limit the number of public company boards that our directors participate on (including our board) to no more than three for audit committee members and those in chief executive officer or equivalent positions or four for those directors who do not fall into one or more of the foregoing categories, without prior approval from the board of directors.

**Director Retirement Guidelines**

Our directors are subject to a retirement policy whereby any director who reaches the age of 78 after January 6, 2022 must tender their resignation to be effective at the end of their then current term.

**Board Committees**

The board of directors currently has the following standing committees: audit, compensation and nominating and governance. The board of directors has adopted a written charter for each standing committee, each of which may be accessed on the Investor Relations section of our website at <u>http://ir.macom.com/governance-documents</u>. A summary of the duties and responsibilities of each committee is set forth below.

***Audit Committee***

Our audit committee consists of Messrs. Ribar, Ritchie and VanLunsen and Ms. Rosenband, with Mr. Ribar serving as Chair. Our audit committee oversees our corporate accounting and financial reporting process, internal accounting and financial controls and audits of our financial statements. Our audit committee also evaluates the independent auditor's qualifications, independence and performance; engages and provides for the compensation of the independent auditor; establishes the policies and procedures for the retention of the independent auditor to perform any proposed permissible non-audit services; reviews our annual audited financial statements; reviews our critical accounting policies, our disclosure controls and procedures and internal controls over financial reporting; discusses with management and the independent auditor the results of the annual audit and the reviews of our quarterly unaudited financial statements; oversees our financial risk assessment and management programs; reviews our information security and technology risks (including cybersecurity), including our information security and risk management programs; and reviews related person transactions that are required to be disclosed under Item 404 of Regulation S-K. Our board of directors has determined that each of our audit committee members meets the requirements for independence and financial literacy under the applicable rules and regulations of the SEC and Nasdaq. Our board of directors has determined that each of Messrs. Ribar, Ritchie, VanLunsen and Ms. Rosenband are audit committee financial experts as defined under the applicable rules and regulations of the SEC.

***Compensation Committee***

Our compensation committee consists of Messrs. Chung, Ribar, Ritchie and VanLunsen, with Mr. Chung serving as Chair. Our compensation committee oversees our compensation plans, policies and programs for our executive officers. The compensation committee is also responsible for overseeing our equity compensation and other employee benefit plans, and for reviewing our Compensation Discussion and Analysis. In addition, the compensation committee oversees our submissions to stockholders on executive compensation matters, including stockholder advisory votes on executive compensation and the frequency of such votes, incentive and other executive compensation plans and amendments to such plans and engagement with proxy advisory firms and other stockholder groups on executive compensation matters. Our board of directors has determined that each member of our compensation committee meets the requirements for independence under the applicable rules and regulations of the SEC and Nasdaq. Pursuant to its charter, the compensation committee may form and delegate authority to subcommittees and delegate authority to one or more designated members of the committee. The compensation committee may also delegate to one or more senior executive officers the authority to make grants of equity-based compensation to eligible non-officer employees, subject to compliance with applicable laws. For additional discussion of the processes and procedures the

------

compensation committee has used to determine executive officer compensation please refer to the section entitled, "Named Executive Officer Compensation, Compensation Discussion and Analysis – How We Set Executive Compensation."

In connection with setting our fiscal year 2022 executive compensation, our compensation committee engaged Pearl Meyer & Partners, LLC ("Pearl Meyer") to support our compensation committee by, among other things, reviewing and recalibrating our peer group of comparable companies, performing benchmarking analyses covering the compensation of our executive officers and advising on compensation plan design structure given stockholder feedback. Please see "Named Executive Officer Compensation, Compensation Discussion and Analysis" for further description of the services and data provided by Pearl Meyer. Prior to continuing Pearl Meyer's engagement, the compensation committee considered the independence of Pearl Meyer in accordance with the terms of its charter. The compensation committee determined that Pearl Meyer was independent and did not identify any conflicts of interest with respect to Pearl Meyer.

***Nominating and Governance Committee***

Our nominating and governance committee consists of Messrs. Bland, Chung and VanLunsen and Ms. Rosenband, with Mr. Bland serving as Chair. The nominating and governance committee is responsible for identifying individuals qualified to become members of our board of directors, receiving and reviewing nominations for such qualified individuals, making recommendations regarding candidates to serve on our board of directors, overseeing evaluations of the board of directors and its committees and exercising oversight concerning the Company's ESG matters. In making recommendations regarding board candidates, the nominating and governance committee will consider desired board member qualifications, expertise, diversity and characteristics. In addition, the nominating and governance committee is responsible for making recommendations concerning governance matters. The nominating and governance committee is also responsible for reviewing and making recommendations concerning the structure and function of the committees of our board of directors, after consultation with the applicable committee chairs, and for reviewing any stockholder proposals relating to governance matters and our response to such proposals. Our board of directors has determined that each member of our nominating and governance committee meets the requirements for independence under the applicable Nasdaq listing rules.

Pursuant to its charter, the nominating and governance committee will also consider qualified director candidates recommended by our stockholders. The nominating and governance committee evaluates the qualifications of candidates properly submitted by stockholders in the same manner as it evaluates the qualifications of director candidates identified by the committee or the board of directors. Stockholders can recommend director candidates by following the instructions outlined below in the section entitled "Additional Information – Consideration of Stockholder-Recommended Director Nominees." No nominations for director were submitted to the nominating and governance committee for consideration by any of our stockholders in connection with the Annual Meeting.

The nominating and governance committee may rely on recommendations from a number of sources when identifying potential director candidates, including recommendations from current directors and officers. The committee may hire outside consultants, search firms or other advisors to assist in identifying director candidates.

When evaluating a candidate for director, the nominating and governance committee considers, among other things, the candidate's judgment, knowledge, integrity, diversity, expertise and strategic, business and industry experience, which are likely to enhance the board of directors' ability to govern our affairs and business. We do not have a separate policy regarding consideration of diversity in identifying director nominees, but the nominating and governance committee strives to nominate directors with a variety of complementary skills and backgrounds so that, as a group, the board of directors will possess a broad perspective and the appropriate talent, skills and expertise to oversee our business. The nominating and governance committee also takes into account independence requirements imposed by law or regulations (including the Nasdaq listing standards). In the case of director candidates recommended by stockholders, the nominating and governance committee may also consider the number of shares held by the recommending stockholder, the length of time that such shares have been held and the relationship, if any, between the recommending stockholder and the recommended director nominee.

***Board Diversity Matrix***

We believe that, as a global company serving a wide variety of markets across multiple geographies, embracing and cultivating diversity is an essential part of serving our customers and increasing stockholder value. Our goal is to reflect our commitment to diversity in the leadership of MACOM, including on the board of directors.

The following diversity statistics are reported in the standardized Nasdaq disclosure matrix for our board of directors.

Bland, Chung, Ocampo, Ribar and Ritchie, Mrs. Ocampo and Ms. Rosenband and the restricted stock awards granted in fiscal year 2022 to Mr. VanLunsen, computed in accordance with FASB ASC Topic 718. For more information on the underlying valuation assumptions used to calculate grant date fair values, see Notes 2 and 19 in the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022. As of September 30, 2022, Messrs.

(2)On March 4, 2022, we granted each of Messrs. Bland, Chung, Ocampo, Ribar and Ritchie and Mrs. Ocampo an annual restricted stock unit award representing 2,768 shares of our common stock for their services as directors during calendar year 2022. In lieu of a restricted stock unit award, Mr. VanLunsen elected to receive a restricted stock award representing 2,768 shares of our common stock for his service as a director during calendar year 2022.

(3)Ms. Rosenband commenced service as a member of the board of directors on September 8, 2022.

(4)On September 9, 2022, we granted Ms. Rosenband an initial restricted stock unit award representing 2,976 shares of our common stock that vests in three substantially equal annual installments beginning November 15, 2023 and an annual restricted stock unit award representing 875 shares of our common stock for her service as a director during calendar year 2022.

Our non-employee directors are compensated under our non-employee director compensation policy, adopted by the board of directors in April 2021, which may be amended or updated from time to time, as described below. Our compensation program for our non-employee directors has two elements: cash compensation and equity-based compensation.

*Cash Compensation.* The cash component of our non-employee director compensation program is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• a $50,000 annual cash retainer for each non-employee director;

&nbsp;&nbsp;&nbsp;&nbsp;• an additional annual cash retainer of $10,000 for each member of the audit committee, $7,500 for each member of the compensation committee and $5,000 for each member of the nominating and governance committee, in each case, other than the chair of such committee;

&nbsp;&nbsp;&nbsp;&nbsp;• an additional annual cash retainer of $20,000 for the chair of the audit committee, $15,000 for the chair of the compensation committee and $10,000 for the chair of the nominating and governance committee; and

&nbsp;&nbsp;&nbsp;&nbsp;• an additional annual cash retainer of $100,000 for the non-employee director chairperson of the board of directors.

These cash payments are calculated and paid in quarterly installments and are prorated for partial quarters of board or committee service. Non-employee directors are also reimbursed for expenses in connection with attendance at board of directors and committee meetings. Non-employee directors are also eligible for coverage under our health care plans at their election.

*Equity Compensation.* For fiscal year 2022, all non-employee directors were eligible to receive equity-based awards under the MACOM Technology Solutions Holdings, Inc. 2021 Omnibus Incentive Plan (our "2021 Omnibus Incentive Plan"). The equity component of our non-employee director compensation program is as follows:

------

&nbsp;&nbsp;&nbsp;&nbsp;• Each of our non-employee directors is granted an annual restricted stock unit award (or, upon the director's request, a restricted stock award) on the first business day following the date of our annual meeting of stockholders representing a number of shares of common stock having a grant date fair market value of approximately $160,000. This award vests in full on the one year anniversary of the grant date, subject to the non-employee director's continued service through such date and the terms of our 2021 Omnibus Incentive Plan. If a non-employee director first joins the board of directors after the annual grant for the calendar year of their appointment or election has been made, then they will be granted an annual restricted stock unit award (or, upon the director's request, a restricted stock award) on the first business day following their appointment or election representing a number of shares of our common stock having an aggregate grant date fair market value equal to $160,000, prorated based on the number of calendar days remaining in the calendar year following such appointment or election. This award vests in full on the first February 15 following its grant date, subject to the non-employee director's continued service through such date and the terms of our 2021 Omnibus Incentive Plan.

&nbsp;&nbsp;&nbsp;&nbsp;• In addition to and not in lieu of the annual grant described above, when a non-employee director first joins the board of directors, they will be granted a one-time initial restricted stock unit award (or, upon the director's request, a restricted stock award) on the first business day following their appointment or election representing a number of shares of our common stock having an aggregate grant date fair market value of approximately $170,000. This award vests in three equal annual installments beginning on the date that is one year following the February 15, May 15, August 15 or November 15 that is soonest to follow the non-employee director's date of appointment or election, in all cases subject to the non-employee director's continued service through such date and the terms of our 2021 Omnibus Incentive Plan. Initial equity grants are not prorated for a non-employee director's first partial year of service.

In accordance with our non-employee director compensation program as in effect at the time, on March 4, 2022 we granted each of Messrs. Bland, Chung, Ocampo, Ribar and Ritchie and Mrs. Ocampo annual restricted stock unit awards representing 2,768 shares of our common stock for his or her service as a director during calendar year 2022, which will vest in full on March 4, 2023, subject to such non-employee director's continued service through such date and the terms of our 2021 Omnibus Incentive Plan. Mr. VanLunsen elected to receive a restricted stock award representing 2,768 shares of our common stock, subject to the same vesting terms as the restricted stock unit awards granted to the directors as outlined above. On September 9, 2022, we granted Ms. Rosenband an initial restricted stock unit award representing 2,976 shares of our common stock, which vests in three substantially equal annual installments beginning November 15, 2023 and an annual restricted stock unit award representing 875 shares of our common stock, which will vest in full on February 15, 2023, subject to Ms. Rosenband's continued service through such date and the terms of our 2021 Omnibus Incentive Plan. Pursuant to our director compensation policy, the initial and annual non-employee director equity awards described above are granted automatically without the need for further action by our board of directors or the compensation committee.

| **COMPENSATION DISCUSSION AND ANALYSIS** |

---

***Named Executive Officers***

This compensation discussion and analysis provides information about our executive compensation programs for fiscal year 2022 as they relate to the following "named executive officers," whose compensation is presented in the tables and accompanying narratives following this discussion:

&nbsp;&nbsp;&nbsp;&nbsp;• Stephen Daly, President and Chief Executive Officer

&nbsp;&nbsp;&nbsp;&nbsp;• John Kober, Senior Vice President and Chief Financial Officer

&nbsp;&nbsp;&nbsp;&nbsp;• Dr. Douglas Carlson, Senior Vice President, Technology

&nbsp;&nbsp;&nbsp;&nbsp;• Robert Dennehy, Senior Vice President, Operations

&nbsp;&nbsp;&nbsp;&nbsp;• Donghyun Thomas Hwang, Senior Vice President, Global Sales

&nbsp;&nbsp;&nbsp;&nbsp;• Ambra Roth, Senior Vice President, General Counsel, Human Resources and Secretary

***Semiconductor Industry Considerations***

The semiconductor industry, in which we operate, is highly competitive, cyclical and characterized by constant and rapid technological change, with evolving standards, short product lifecycles and significant fluctuations in supply and demand, all of which may have a material impact on our business and employee compensation, among other things. Downturns in the semiconductor industry may be prolonged and difficult or impossible to predict, and downturns in many sectors of the electronic systems industry have, in the past, contributed to extended periods of weak demand for semiconductor products. We have experienced decreases in our revenue, profitability, cash flows and stock price during such downturns in the past, and may be similarly affected by future downturns, particularly if we are unable to effectively respond to reduced demand in a particular market. In addition, the competition for attracting and retaining qualified talent within our industry is fierce.

Our compensation programs take our industry dynamics into consideration with regard to how we establish such programs across the organization, including the programs for our executive officers and our broader employee base. For example, our executive compensation programs generally place a larger proportion of each executive's compensation in performance-based equity elements and our short-term cash incentive program is structured to address the cyclical and highly competitive nature of the industry and environment in which we operate.

***Objectives of Our Executive Compensation Programs***

The compensation committee of our board of directors oversees the compensation programs covering our executive officers, including our named executive officers, under its authority as delegated by our board of directors. These compensation programs are designed to:

&nbsp;&nbsp;&nbsp;&nbsp;• attract and retain the best executive talent;

&nbsp;&nbsp;&nbsp;&nbsp;• motivate our executives to achieve our financial and business goals; and

&nbsp;&nbsp;&nbsp;&nbsp;• align our executives' interests with those of our stockholders to drive increased stockholder value.

To achieve these goals, we structure our executive compensation programs to provide a competitive level of total compensation and create a strong connection between our financial and business results by linking a significant portion of each executive's compensation to the achievement of specific performance goals that we expect will increase stockholder value. The key elements of the performance-based compensation provided to our named executive officers in fiscal year 2022 were our equity program, which included performance-based restricted stock units, and our cash incentive programs, each as described below.

------

***How We Set Executive Compensation***

The compensation program in effect for our named executive officers for fiscal year 2022 reflects a combination of individually negotiated compensation arrangements that we have entered into with certain of our named executive officers, as described below, and a total compensation program for our executive officers developed in prior periods by our compensation committee and further refined by it in fiscal year 2022 as described in more detail below. Our compensation committee annually reviews and periodically adjusts the total compensation payable to our named executive officers based on the information and factors discussed below and recommendations made by our Chief Executive Officer (other than with respect to his own compensation) from time to time.

In connection with its engagement of Pearl Meyer (as noted elsewhere in this Proxy Statement), our compensation committee reviewed our peer group at the beginning of fiscal year 2022, which included companies in the semiconductor, electric components, communications equipment and electronic manufacturing industries. The compensation committee's assessment of potential peers included whether the companies are direct market share competitors, broader competitors for employee talent and industry comparators, as well as the frequency the comparators were used as a peer compensation benchmarks among other companies in the peer group. Potential peers were also assessed based on their relative size, including trailing quarterly and annual revenue as well as market capitalization as of December 31, 2020 and October 6, 2021, relative gross margins and research and development ("R&D") expense and their market capitalization to revenue ratio, recognizing that there are a limited number of direct market share comparators of similar size to us. The revenue range of the selected companies varied between $452 million and $4.3 billion, and market capitalization (as of October 1, 2021) varied between $2.6 billion and $23.8 billion. Our relative positioning was at the 14<sup>th</sup> percentile of revenue and the 21<sup>st</sup> percentile of market capitalization. Selected peers were unchanged from the prior fiscal year and consisted of the following companies: II-VI, Inc., Allegro MicroSystems, Inc., Belden Inc., Diodes, Inc., IPG Photonics Corp., Lattice Semiconductor Corp., Lumentum Holdings, Inc., MaxLinear, Inc., Monolithic Power Systems, Inc., Power Integrations, Inc., Qorvo, Inc., Semtech Corp., Silicon Laboratories, Inc. and Wolfspeed, Inc.

Based on the analysis and guidance provided by Pearl Meyer, including industry total compensation and peer proxy statement data, as well as subjective factors, such as the relative importance we place on each role within the Company, internal pay equity and other factors, in October 2021, our compensation committee established fiscal year 2022 total target direct compensation levels for our named executive officers that were above the corresponding levels from fiscal year 2021. Our compensation committee, in connection with Pearl Meyer, also reviewed our total compensation program, primarily consisting of base salary, short-term cash incentives and long-term equity incentives, as discussed in further detail below, with the intention of ensuring that the program was designed to provide each executive officer with the opportunity to realize targeted total compensation while furthering the objectives of our executive compensation programs described above. As a result of the advice and guidance provided by Pearl Meyer, our compensation committee decided to introduce a relative total shareholder return ("rTSR") component in our executive compensation program in fiscal year 2022. Please see the "Performance-Based Equity Incentives- rTSR PSUs" section of this Proxy Statement for more information concerning the rTSR PSUs (as defined below). Based on our review of the data described above, we believe that the total compensation provided to our named executive officers in fiscal year 2022 was generally slightly below market median to market median overall assuming achievement of our target performance goals applicable to the short-term cash incentives and long-term equity incentives granted to such named executive officers in fiscal year 2022 (discussed in more detail below), and market median to above market median overall assuming achievement of our maximum performance goals.

**Ongoing Stockholder Outreach Initiative**

The board of directors values the opinions of our stockholders in matters related to corporate governance, executive compensation and other matters. Our fiscal year 2022 executive compensation program reflected the extensive stockholder outreach initiative undertaken by members of our senior management team and investor relations, as well as members of our compensation committee from September 2021 to November 2021, which was focused on understanding the perspectives and concerns of our stockholders following the results of our say-on-pay vote at our 2021 annual meeting of stockholders. We believe that our stockholders strongly supported the design changes that we made to our fiscal year 2022 program, as reflected by their approval, on an advisory basis, of the compensation of our named executive officers by 98.64% of the shares voted at our 2022 annual meeting. In December 2022, we conducted additional investor outreach involving members of our senior management team and investor relations. This outreach focused on better understanding the concerns and perspectives of our stockholders and providing updates to our investors on various topics, including with regard to our ESG program, Board composition and corporate governance.

***Elements of Executive Compensation***

Our compensation programs for our named executive officers primarily consist of the following elements:

&nbsp;&nbsp;&nbsp;&nbsp;• base salary and benefits;

------

&nbsp;&nbsp;&nbsp;&nbsp;• short-term cash incentives; and

&nbsp;&nbsp;&nbsp;&nbsp;• long-term equity incentives.

**Base Salary**

The base salary for each of our named executive officers for fiscal year 2022 was determined by our compensation committee and is intended to reflect each executive's relative level of experience and responsibility.

In fiscal year 2022, the compensation committee approved a 3.7% annual base salary increase for Mr. Daly, an 11.8% annual base salary increase for Mr. Kober to better align his base salary with experienced industry peers and a 2.6% annual base salary increase for each of Dr. Carlson, Messrs. Dennehy and Hwang and Ms. Roth, in each case, based on standard merit increases and taking into account the continued desire to align our executive officers' compensation with our industry peers. In determining these base salary increases, our compensation committee considered the industry total compensation and proxy statement data discussed above provided by Pearl Meyer. Based on such considerations, our compensation committee determined that such base salary increases were appropriate to maintain competitive levels of base salary for each of these individuals.

The following table shows the annual base salaries for each of our named executive officers as of the end of fiscal year 2022.

**Short-Term Cash Incentives**

Our compensation committee determined the annual target cash incentive opportunities for each of our named executive officers for fiscal year 2022 based on its business judgment regarding the appropriate level of incentive opportunities to motivate and retain these executives, and to establish an appropriate "pay for performance" linkage between their total compensation and our overall financial results. In making this business judgment, our compensation committee considered each named executive officer's historical level of incentive opportunities, base salary and level of incentive opportunities relative to those of our other named executive officers and the industry total compensation and proxy statement data discussed above. Based on these considerations, our compensation committee approved the annual target cash incentive opportunities (as a percentage of base salary) for all of our named executive officers for fiscal year 2022, which was at the same level set in fiscal year 2021 for Mr. Daly and at a level 5% higher than as set in fiscal year 2021 for each of Messrs. Kober, Dennehy and Hwang, Dr. Carlson and Ms. Roth, taking into account the continued desire to align our executive officers' compensation with our industry peers. The incentive opportunity for our named executive officers was also subject to potential discretionary increase or reduction based on individual performance during the period. The following table shows the target annual cash incentive opportunity of each of our named executive officers for fiscal year 2022 depending on achievement against applicable performance metrics, expressed as a percentage of each executive's annual base salary.

As discussed above, the semiconductor industry is intensely competitive and can be highly cyclical, which is why we have historically comprised our short-term cash incentives for our entire organization, including our executive officers, of two six-month performance periods within our fiscal year, with performance goals for each period based on non-GAAP adjusted operating income during the applicable period. The structure of the short-term cash incentive program remains unchanged, and, consistent with certain prior fiscal years, our failure to meet the pre-determined targets means that no cash incentive payments would be made. Each of our named executive officers has an opportunity to earn one half of their applicable annual target cash incentive opportunity amount during each six-month period. The two six-month periods within our short-term cash incentive program allow us to adjust our targets for the then-forthcoming six months based on changing business conditions, which we feel provides us with an opportunity to meet our compensation objectives outlined above. In each of the past two fiscal years, given that our first six-month short-term cash incentive period performance exceeded our annual business plan expectations, and to provide for improving performance targets while ensuring that such targets were meaningful for our named executive officers and stockholders, the compensation committee increased the performance targets in the second six-month period to be in excess of amounts that would have otherwise been established if we had utilized the targets in our annual business plan.

In addition, over the past three fiscal years, in an effort to balance amounts paid to employees along with stockholder return, we instituted short-term cash incentive program caps to limit the maximum payouts to our named executive officers. In fiscal years 2019 and prior, our executive officers were entitled to receive up to 200% of their six-month target cash incentive opportunity, whereas during the first six-month periods in fiscal years 2020 and 2021, the maximum program payout was limited to 100% of the target, during the first six-month period of fiscal year 2022, the maximum program payout was limited to 175% of the target and, for the second six-month periods of fiscal years 2020 and 2021, the maximum payout was limited to 150% and 175%, respectively of the relevant target. In a continued effort to balance amounts paid to employees along with stockholder return, the short-term cash incentive program cap was restored to 200% for the second six-month period of fiscal year 2022.

For fiscal year 2022, we selected adjusted operating income as the performance metric for these short-term cash incentive programs because we believe it is a driver of stockholder value. The calculation of adjusted operating income excludes the impact of accrued costs for the payment of incentives under the short-term cash incentive program itself, as well as the effect, where applicable, of amortization expense, share-based compensation expense, impairment and restructuring charges and acquisition- and integration-related costs.

Our compensation committee determined the adjusted operating income goals for each performance period generally based on our historic adjusted operating income, our annual business plan and sequential revenue and operating profit projections. These goals were intended to be challenging, yet attainable, and to align the interests of our named executive officers with those of our stockholders by providing for a payout only in the event of exceptional performance that the compensation committee believed could result in a meaningful increase in stockholder value. We typically establish three separate adjusted operating income objectives in connection with each six-month period including a threshold amount, which if not achieved, results in no bonus being earned, a target amount, which would align with the target established for each named executive officer, and a maximum amount, which could provide potential upside above the established targets.

The table below summarizes the adjusted operating income amounts established for threshold, target, maximum and actual performance, as well as the associated percentages of the target earned, for each of the six-month periods over the past four fiscal years. Adjusted operating income in the table below excludes bonus expense.

\* The maximum performance opportunity was reduced to below the 200% permissible under the plan for each of the performance periods for fiscal years 2020 and 2021 and the first half of fiscal year 2022.

*First Half Fiscal Year 2022 Program (one-half of the named executive officer's Annual Target Cash Incentive opportunity).* The performance goals above were established such that the achievement at or below the threshold performance goal would not result in a payout for the named executive officer, the achievement of the target performance goal would result in a payout of one half of 100% of the named executive officer's annual target cash incentive opportunity and the achievement of the maximum performance goal would result in a payout of one half of 175% of the named executive officer's annual target cash incentive opportunity.

Under the first half fiscal year 2022 program, a total pool for all participating employees within the Company would be funded at approximately $6.0 million for target performance and $10.5 million for meeting or exceeding maximum performance. Each of Messrs. Daly, Kober, Dennehy and Hwang, Dr. Carlson and Ms. Roth would be eligible for a payment based on an allocated portion of this pool based on the executive's target incentive amount, with discretionary adjustments based on individual performance. There was no set weighting assigned by the compensation committee with respect to the individual performance component of the cash incentive program.

In light of our performance for the first half of fiscal year 2022 (see the "Actual Performance" column in the table above), each named executive officer received a cash incentive payment for the first half of fiscal year 2022 equal to 138% of their first half target level, which was the approved payout based on straight-line interpolation between target and maximum performance levels. Following review of each individual's performance, the compensation committee did not make discretionary adjustments based on individual performance.

*Second Half Fiscal Year 2022 Program (one-half of the named executive officer's Annual Target Cash Incentive opportunity).* The performance goals above were established such that the achievement at or below the threshold performance goal would not result in a payout to the named executive officer, the achievement of the target performance goal would result in a payout of one half of 100% of the named executive officer's annual target cash incentive opportunity and the achievement of the maximum performance goal would result in a payout of one half of 200% of the named executive officer's annual target cash incentive opportunity.

Under the second half fiscal year 2022 program, a total pool for all participating employees within the Company would be funded at $6.2 million for meeting target performance and $12.4 million for meeting or exceeding maximum performance. Each of Messrs. Daly, Kober, Dennehy and Hwang, Dr. Carlson and Ms. Roth would be eligible for a payment based on an allocated portion of this pool based on the executive's target incentive amount, with discretionary adjustments based on individual performance. There was no set weighting assigned by the compensation committee with respect to the individual performance component of the cash incentive program.

In light of our performance for the second half of fiscal year 2022 (see the "Actual Performance" column in the table above), each named executive officer received a cash incentive payment for the second half of fiscal year 2022 equal to 138% of their second half target level, which was the approved payout based on straight-line interpolation between target and maximum performance levels. Following review of each individual's performance, the compensation committee did not make discretionary adjustments based on individual performance.

------

*Aggregate Fiscal Year 2022 Program (total of the named executive officer's Annual Target Cash Incentive opportunity).* The total cash incentive opportunity earned for each of our executive officers during fiscal year 2022 was 138% of each executive's respective target annual cash incentive opportunity.

**Long-Term Equity Incentives**

Our fiscal year 2022 long-term equity incentive program was comprised of three components: time-based restricted stock units, Adjusted EPS performance-based restricted stock units and rTSR performance-based restricted stock units. In fiscal year 2022, our compensation committee granted to each of Messrs. Daly, Kober, Dennehy and Hwang, Dr. Carlson and Ms. Roth both time-based restricted stock units and Adjusted EPS and rTSR performance-based restricted stock units. For all of our named executive officers other than Mr. Daly, approximately 15% of the total value of the award was allocated to time-based restricted stock units and approximately 85% was allocated to performance-based restricted stock units. For Mr. Daly, approximately 13% of the total value of the award was allocated to time-based restricted stock units and approximately 87% was allocated to performance-based restricted stock units.

![chart-176c70e4a9604410895.jpg](chart-176c70e4a9604410895.jpg)![chart-5d187a047bdc462191e.jpg](chart-5d187a047bdc462191e.jpg)

The size of each award was determined by the compensation committee based on its consideration of named executive officer individual performance and the industry total compensation and proxy statement benchmarking data provided by Pearl Meyer as described above.

*Performance-Based Equity Incentives- Adjusted EPS PSUs*

In fiscal year 2022, we granted Mr. Daly 16,109 restricted stock units, Mr. Kober 7,477 restricted stock units, Dr. Carlson 4,566 restricted stock units, Mr. Dennehy 4,566 restricted stock units, Mr. Hwang 4,566 restricted stock units and Ms. Roth 4,566 restricted stock units, in each case, subject to the performance-based vesting conditions described below.

As was the case in prior years, certain performance-based restricted stock units are eligible to be earned and vest based on our Adjusted EPS ("Adjusted EPS PSUs") growth during the applicable performance period. Adjusted EPS is a non-GAAP financial metric. Our calculation of Adjusted EPS is calculated by dividing Adjusted net income, which excludes intangible amortization expense, share-based compensation costs, changes in common stock warrant liability, non-cash interest, equity investment gains and losses, loss on debt extinguishment, as well as certain tax items, by Adjusted diluted shares. Adjusted EPS growth was selected as the applicable performance metric for performance-based restricted stock units granted in fiscal year 2022 and prior fiscal years because our compensation committee believes that growth in Adjusted EPS is a key driver of increases in stockholder value. An explanation of how we calculate Adjusted EPS is contained in Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on November 3, 2022.

The Adjusted EPS PSUs granted to our named executive officers in fiscal year 2022 are divided into three equal tranches, with one tranche eligible to be earned and to vest based on our Adjusted EPS growth during fiscal year 2022, one tranche eligible to be earned and to vest based on Adjusted EPS growth during fiscal years 2022-2023 and one tranche eligible to be earned and to vest based on Adjusted EPS growth during fiscal years 2022-2024, with Adjusted EPS growth goals for performance periods spanning multiple fiscal years based on compound annual growth. For each tranche, recipients can earn between 0% to 300% of the target number of Adjusted EPS PSUs, depending on actual performance, with 50% of the target number of Adjusted EPS PSUs earned if threshold performance is achieved (Adjusted EPS growth of 5%), 100% of the target number of Adjusted EPS PSUs earned if target performance is achieved (Adjusted EPS growth of 10%), 200% of the target number of Adjusted EPS PSUs earned if upside performance is achieved (Adjusted EPS growth of 20%) and 300% of the target number of Adjusted EPS PSUs earned if maximum performance is achieved (Adjusted EPS growth of 30%), and, in each case, with straight-line interpolation between performance levels. To the extent earned, Adjusted EPS PSUs for each tranche will vest and be settled

------

following the announcement to the financial markets of our financial performance associated with the applicable performance period, generally subject to continued employment with us through the settlement date. If Adjusted EPS PSUs for a tranche are not earned, they will be forfeited and are not eligible to be achieved in subsequent performance periods (i.e., there is no catch-up or retesting feature).

Each of our named executive officers also held Adjusted EPS PSUs that were granted in prior fiscal years and that were eligible to vest based on Adjusted EPS growth during a performance period that included fiscal year 2022.

The table below sets forth (1) Adjusted EPS growth goals for Adjusted EPS PSUs granted in fiscal year 2022, (2) Adjusted EPS growth goals for Adjusted EPS PSUs granted in previous years with a performance period that included fiscal year 2022, (3) our actual Adjusted EPS growth for the applicable performance period and (4) the percentage of Adjusted EPS PSUs that were earned based on such performance:

|:---|:---|:---|:---|:---|:---|:---|:---|
| **Fiscal Year of Grant** | **Performance Period (Fiscal Year(s))** | **Threshold <br>(50% of Target Tranche of Adjusted EPS PSUs Earned)** | **Target (100% of Target Tranche of Adjusted EPS PSUs Earned)** | **Upside (200% of <br>Target Tranche of Adjusted EPS PSUs Earned)** | **Maximum <br>(300% of Target Tranche of Adjusted EPS PSUs Earned)** | **Actual Performance** | **% of Target Tranche of Adjusted EPS PSUs Earned** |
| 2022 | 2022 | 5% | 10% | 20% | 30% | 31% | 300% |
| 2021 | 2021-2022 | 5% | 10% | 20% | 30% | 69% | 300% |
| 2020 | 2020-2022 | 5% | 10% | 20% | 30% | 84% | 300% |

---

Our Adjusted EPS performance has shown significant improvement during fiscal years 2020, 2021 and 2022 as compared to earlier periods which has resulted in the maximum payouts being achieved.

*Performance-Based Equity Incentives- rTSR PSUs*

In fiscal year 2022, our compensation committee made the determination to add an rTSR metric with a long-term stock performance cycle to certain performance-based restricted stock units granted to our executive officers ("rTSR PSUs"). The rTSR metric was added to our overall executive compensation program in response to stockholder feedback and to further align the interests of our executive officers with those of our stockholders.

In fiscal year 2022, we granted Mr. Daly 53,698 restricted stock units, Mr. Kober 21,862 restricted stock units, Dr. Carlson 12,273 restricted stock units, Mr. Dennehy 12,273 restricted stock units, Mr. Hwang 12,273 restricted stock units and Ms. Roth 12,273 restricted stock units, in each case, subject to the performance-based vesting conditions described below.

The fiscal year 2022 rTSR PSUs are performance-based restricted stock units that can be earned at varying amounts based on our performance relative to component companies of the PHLX Semiconductor Index over a three-year period beginning October 2, 2021, and ending September 27, 2024. The rTSR PSUs will result in a more significant portion of each executive's fiscal year 2022 compensation being tied to our long-term stock performance as compared to prior years. Our compensation committee believes that balancing the objective financial measures of the Adjusted EPS PSUs with restricted stock units subject to an rTSR component will further incentivize our named executive officers to focus on outperforming our peers over a longer period in a highly competitive marketplace and further align their interests with those of our stockholders.

The amount of rTSR PSUs earned at the end of the performance period will be determined as follows: rTSR rank equal to or less than the 25<sup>th</sup> percentile results in no payout; rTSR rank greater than the 25<sup>th</sup> percentile and less than or equal to the 50<sup>th</sup> percentile results in payout of between 50% and 100% of the target shares, rTSR rank greater than the 50<sup>th</sup> percentile and less than or equal to the 75<sup>th</sup> percentile results in payout of between 100% and 200% of the target shares and rTSR rank performance greater than the 75<sup>th</sup> percentile results in payout of 200% of the target number of shares.

Mr. Daly also held an rTSR PSU award that was granted in fiscal year 2019 and that was eligible to vest based on the Company's total shareholder return compared to a peer group of companies in the Nasdaq composite index during fiscal years 2020 through 2022. In October 2021, our compensation committee made the determination to align the vesting date of Mr. Daly's new hire rTSR PSU award with the end of the performance period applicable to the rTSR PSU award. The actual payout earned for such award was subsequently certified by our compensation committee and the award vested and was settled in November 2022 as described in more detail below.

The table below sets forth (1) rTSR rank goals for Mr. Daly's rTSR PSUs granted in fiscal year 2019, (2) our actual rTSR rank for the applicable performance period and (3) the percentage of rTSR PSUs that were earned based on such performance:

| 2019 | 2020-2022 | >25% and ≤50% | >50% and ≤75% | >75% | 83% | 150% |

---

*Time-Based Equity Incentives*

In fiscal year 2022, as part of our annual equity compensation program, we also provided each of our named executive officers with long-term equity incentives through the grant of restricted stock units subject to time-based vesting ("RSUs"). Our compensation committee granted RSUs because it believes they provide a valuable retention incentive to our executives. In addition, our compensation committee believes that because RSUs require fewer shares to deliver the same amount of retention incentive to a given executive as compared with a stock option award, RSUs also reduce the overall potential dilution to our stockholders from our equity compensation programs.

In fiscal year 2022, we granted Mr. Daly 10,740 RSUs, Mr. Kober 4,985 RSUs, Dr. Carlson 3,044 RSUs, Mr. Dennehy 3,044 RSUs, Mr. Hwang 3,044 RSUs and Ms. Roth 3,044 RSUs, in each case, subject to time-based vesting based on his or her continued employment with us over three years. Our compensation committee approved these RSU awards based on its review of peer group data provided by Pearl Meyer, together with its business judgment as to the appropriate level of the long-term incentive compensation necessary to retain these executives.

**Benefits** 

We generally provide our named executive officers health and welfare benefits, including health benefits and life insurance coverage, as well as the opportunity to participate in and receive matching contributions under our 401(k) plan, in each case, on the same terms as our other salaried employees. We also reimburse up to $2,500 per year in personal tax and financial planning expenses for our executive officers.

**Severance Arrangements**

We believe it is in our best interests and the best interests of our stockholders to encourage and reinforce the continued dedication and attention of our President and Chief Executive Officer, and to minimize the potential for him to be distracted from performing his duties by the potential prospect of a termination of employment. Therefore, we have agreed to provide our President and Chief Executive Officer with severance benefits as set forth in his employment agreement, as described below under "Potential Payments upon Termination or Change in Control".

In October 2014, following a period of heavy consolidation in our industry and with a similar motivation of keeping our executives focused on managing our business without distraction by a potential change in control, we adopted the MACOM Technology Solutions Holdings, Inc. Change in Control Plan (as amended, the "CIC Plan"), which was subsequently amended in 2017 and in 2022. Each of our named executive officers participates in the CIC Plan. The CIC Plan provides severance protection to plan participants in the event their employment is terminated under certain circumstances in connection with a change in control. In adopting and subsequently amending the CIC Plan, our compensation committee was motivated by a belief that the benefits of the plan were reasonable in scope and amount, would better align the interests of our executives with those of our stockholders in the context of a potential change in control and may enhance stockholder value whether or not a future change in control occurs by helping to retain those executives who are participants in this plan. See "Potential Payments upon Termination or Change in Control" below for a more detailed discussion of these potential payments to our named executive officers.

In fiscal year 2022, in response to stockholder feedback, the compensation committee approved an amendment to the CIC Plan to eliminate excise tax gross-ups relating to Section 280G of the Internal Revenue Code of 1986, as amended (the "Code") for plan participants who commence participation in the plan on or after January 1, 2022.

------

**Restrictive Covenants**

From time to time we enter into restrictive covenant agreements with certain of our key executives in order to secure the employment of those persons who may be key to our success for a period of time, to prevent competitors from hiring such personnel away from us, and to protect our confidential information, intellectual property and relationships with employees, independent contractors, vendors and customers. Mr. Daly's employment agreement contains non-solicitation provisions pursuant to which he has agreed not to solicit our employees, consultants, customers, partners or vendors during his employment and for a period of 12 months following termination of his employment. All of our named executive officers are party to a Confidentiality and Invention Assignment Agreement, under which they have agreed not to solicit our employees, consultants, customers, partners or vendors during their employment and for 12 months following termination of employment and have agreed to a perpetual confidentiality covenant and an assignment of intellectual property covenant.

**Compensation Risk Assessment**

Our compensation committee regularly reviews the Company's compensation and benefits programs, policies and practices, including its executive compensation program and its incentive-based compensation programs for its executive officers, to determine whether such programs, policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. Our compensation and governance-related policies are enhanced by our clawback policy, described below, as well as a policy prohibiting hedging and pledging of our securities by our directors and officers, including our executive officers. Based on its assessment, our compensation committee does not believe that our compensation programs, policies and practices, in conjunction with our existing processes and controls, create risks that are reasonably likely to have a material adverse effect on our business and operations.

**Clawback Policy**

In November 2018, we adopted a clawback policy that covers our current and former employees at the level of Vice President and above, including all of our named executive officers. Under the policy, if there is a restatement of our financial results due to material non-compliance with financial reporting requirements, certain cash- and equity-based incentive compensation paid or awarded to covered employees will be subject to cancellation and/or repayment, in our compensation committee's discretion, if it was based on the erroneous financial results, was in excess of the amount that would have otherwise been paid or awarded and the employee's conduct was a material factor in the obligation to restate the results.

**Tax and Accounting Considerations**

Section 162(m) of the Code disallows a tax deduction to a public corporation for annual compensation in excess of $1 million paid to certain of its executive officers. Therefore, compensation paid to certain of our executive officers in excess of $1 million in a taxable year will not be deductible. Our compensation committee believes that its primary responsibility is to provide a compensation program that attracts, retains and rewards the executives who are necessary for our success. Accordingly, and in furtherance of that responsibility, our compensation committee has authorized and will, in its judgment, continue to authorize compensation that may otherwise be limited as to tax deductibility.

Our compensation committee also considers the accounting implications of significant compensation decisions, including decisions that relate to our equity incentive plans and programs. If accounting standards change, we may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

------

**Stock Ownership Guidelines**

Effective December 21, 2021, our compensation committee established executive officer stock ownership guidelines to further align the interests of our executive officers with the interests of our stockholders and to promote sound corporate governance. The guidelines for executive officers are determined as a multiple of the executive officer's annual base salary. Our Chief Executive Officer is required to hold shares of our common stock with a value equal to at least four times his annual base salary. Our Chief Financial Officer is required to hold shares of our common stock with a value equal to at least two times his annual base salary. Each other executive officer is required to hold shares of our common stock with a value equal to at least one times his or her annual base salary. Executive officers are required to achieve the applicable level of ownership within 48 months of the later of December 21, 2021 or the date the person was initially designated an executive officer. Unvested equity awards (other than unvested time-based restricted stock units), vested stock options, vested stock appreciation rights and unearned performance-based equity awards do not count towards satisfaction of the stock ownership guidelines.

**Say-on-Pay**

At our 2021 annual meeting of stockholders, our stockholders approved on an advisory basis to hold future advisory votes on the compensation of our named executive officers annually. At our 2022 annual meeting of stockholders, our stockholders approved, on an advisory basis, the compensation of our named executive officers by 98.64% of the shares voted.

(1)The amounts included under the "Stock Awards" column include the aggregate grant date fair value of the restricted stock unit awards granted in each respective fiscal year, computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. For more information on the underlying valuation assumptions used to calculate grant date fair values, see Notes 2 and 19 in the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022. With respect to the Adjusted EPS performance-based restricted stock unit awards granted to our named executive officers during fiscal year 2022, the aggregate grant date fair value of such awards was determined based on the probable outcome of the performance conditions associated with such awards, which was determined to be 100% of target levels. The aggregate grant date fair value of such awards would be $3,195,381, $1,483,138, $905,712, and $905,712 for each of Messrs. Daly, Kober, Dennehy and Hwang, respectively, and $905,712 for Dr. Carlson, and $905,712 for Ms. Roth if maximum performance levels were achieved for all three tranches. With respect to the rTSR performance-based restricted stock unit awards granted to our named executive officers during fiscal year 2022, the aggregate grant date fair value of such awards was determined using a Monte Carlo simulation model which considers all potential outcomes, and therefore expense recognition for such awards is not subject to probable or maximum outcome assumptions under FASB ASC Topic 718. For more information on the underlying valuation assumptions used to calculate grant date fair values, see Note 19 in the Notes to Consolidated Financial Statements in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022.

(2)The amounts included under the "Non-Equity Incentive Plan Compensation" column reflect the cash incentives earned by each named executive officer under our cash incentive programs for each fiscal year. See "Named Executive Officer Compensation, Compensation Discussion and Analysis – Short-Term Cash Incentives" for a more detailed description of these programs for fiscal year 2022.

(3)The amounts included under the "All Other Compensation" column reflect the following amounts for each named executive officer for fiscal year 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(2)For stock awards, the value realized is based on the closing price of our common stock on the vesting date.

**Pension Benefits**

We currently do not (and did not in fiscal year 2022) sponsor any defined benefit pension or other actuarial plan in which our named executive officers participate.

**Nonqualified Deferred Compensation**

We currently do not (and did not in fiscal year 2022) maintain any nonqualified defined contribution or other deferred compensation plan or arrangement for our named executive officers.

**Potential Payments upon Termination or Change in Control**

The table below reflects, as applicable, cash severance, equity acceleration and continuation of health benefits payable to our named executive officers in connection with a termination of employment by the Company without cause or a resignation by the executive for good reason within three months prior to or two years following a "change in control," in each case assuming that such triggering event took place on September 30, 2022, and based on the closing price of our common stock on this date, $51.79, to the extent applicable, and for Mr. Daly, in connection with the termination of his employment relationship by the Company without cause (as defined in his employment agreement) or resignation by him for good reason (as defined in his employment agreement).

*Severance Entitlements and Payments*

Mr. Daly is party to an employment agreement with the Company that provides for payments upon an involuntary termination of employment by the Company other than for "cause" (as defined in his employment agreement) and upon a termination of employment by him for "good reason" (as defined in his employment agreement). Pursuant to Mr. Daly's employment agreement, if his employment is terminated by the Company other than for cause or if he resigns for good reason, he would be entitled to receive continued monthly base salary and reimbursements of the Company's portion of medical and dental benefit premiums (subject to certain conditions) for twelve months following his termination of employment, a prorated annual bonus for the year of termination, based on actual performance, accelerated vesting of his new hire grant of 136,239 restricted stock units (which vested as to 20% of the restricted stock units on May 16, 2020 and 10% of the restricted stock units on each of November 16, 2020, May 16, 2021, November 16, 2021, May 16, 2022, and November 16, 2022, respectively, and will vest as to 10% of the restricted stock units on each six-month anniversary thereafter, generally subject to Mr. Daly's continued employment through each applicable vesting date), and twelve months' accelerated vesting credit for any other outstanding equity awards that vest solely based on continued employment or service with us. In addition, Mr. Daly's equity awards would remain exercisable for one year following termination of employment. Mr. Daly will be subject to non-solicitation restrictions for the period during which he is entitled to receive salary continuation.

*CIC Plan*

The CIC Plan, in which each of our current named executive officers is a participant, provides that:

&nbsp;&nbsp;&nbsp;&nbsp;• immediately prior to a "change in control" (as defined in the CIC Plan), subject to the terms and conditions contained in the CIC Plan, any performance-based equity awards held by a participant will be deemed earned at maximum levels of

------

performance as of immediately prior to the change in control and become exercisable, vested and/or payable on the later of the end of the originally applicable performance period and any further service-based vesting period relating to such award, subject to the participant's continued employment except as set forth below;

&nbsp;&nbsp;&nbsp;&nbsp;• if a change in control occurs and a participant's employment is terminated by us without "cause" (as defined in the CIC Plan) or a participant resigns from employment with us for "good reason" (as defined in the CIC Plan), in each case, within three months prior to and in connection with the change of control or within the two-year period following the change in control, the participant will be entitled to the following payments and benefits:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ the sum of the participant's annual base salary and target annual bonus for the year in which the termination occurs (multiplied by 2.0 for Mr. Daly and 1.5 for Mr. Kober), payable in a lump sum;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ a prorated annual bonus based on the participant's target annual bonus or, if greater and the termination of employment occurs in the second half of the applicable bonus period, the estimated actual amount of such annual bonus;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ a lump sum amount equal to the Company's estimate of the total cost of medical, dental and vision continuation coverage under the Company's group health plan for the participant and his participating dependents for 24 months, in the case of Mr. Daly, 18 months, in the case of Mr. Kober, or 12 months for each of the other named executive officers, in each case, increased by the amount of federal and state taxes imposed on such payments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;◦ full vesting of all outstanding equity awards held by the participant.

Since all of our current named executive officers were participants in the CIC Plan prior to January 1, 2022, we will make an additional lump sum cash payment to a named executive officer if he or she becomes subject to an excise tax under Section 4999 of the Code as a result of any payment or benefit made or provided under the CIC Plan, either alone or when aggregated with any other payments or benefits. The net result of the additional payment is to place the participant in the same after-tax position as if the excise tax had not been imposed.

In the event that a participant has an existing agreement with us relating to the participant's potential rights to severance pay, equity acceleration or benefits in connection with a change in control, such rights will be superseded by the rights of the participant under the CIC Plan with respect to any change in control occurring during the term of the CIC Plan, but such agreement otherwise will remain enforceable and in full force and effect.

*Potential Payments upon Termination or Change in Control Table*

A summary of the potential payments that each of our current named executive officers would have received upon the occurrence of these events, assuming that each triggering event occurred on September 30, 2022, is set forth below.

&nbsp;&nbsp;&nbsp;&nbsp;(1)"Involuntary Termination" as used in this column includes involuntary termination without cause or a voluntary termination with good reason, as provided in Mr. Daly's employment agreement. The amount included in the "Severance" column in respect of an annual bonus in fiscal year 2022 reflects the actual bonus earned by Mr. Daly in respect of fiscal year 2022. Amounts listed in the "Health Insurance Benefits" column have been calculated assuming that the cost of medical, dental and vision continuation coverage under the Company's group health plan is $2,200 per month.

------

&nbsp;&nbsp;&nbsp;&nbsp;(2)All amounts listed beneath this heading represent benefits potentially payable under the CIC Plan. "Involuntary Termination" as used in this column includes involuntary termination without cause or a voluntary termination with good reason, as and to the extent provided for in the CIC Plan. Amounts listed in the "Severance" column are based on the annual base salaries and target annual bonuses in effect as of September 30, 2022 and have been calculated assuming that each named executive officer receives a prorated annual bonus for the year of termination of employment equal to his or her target annual bonus. Amounts listed in the "Health Insurance Benefits" column have been calculated assuming that the cost of medical, dental and vision continuation coverage under the Company's group health plan is $2,200 per month.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Amounts are based on the fair market value of our common stock of $51.79 per share, which was the closing price of our common stock on September 30, 2022 as reported on Nasdaq, and have been calculated assuming that all outstanding equity awards held by the applicable named executive officer that are scheduled to vest based on the named executive officer's continued service within twelve months following September 30, 2022 vest in full and that the 54,500 unvested RSUs granted to Mr. Daly vest in full pursuant to the terms of his employment agreement.

&nbsp;&nbsp;&nbsp;&nbsp;(4)Amounts are based on the fair market value of our common stock of $51.79 per share, which was the closing price of our common stock on September 30, 2022 as reported on Nasdaq, and have been calculated assuming that all outstanding equity awards vest in full, with outstanding performance-based restricted stock units earned at maximum with respect to future fiscal years.

&nbsp;&nbsp;&nbsp;&nbsp;(5)Amounts listed represent an estimate of the additional lump-sum payment that would be payable if a named executive officer became subject to the excise tax under Section 4999 of the Code, as described above based on the assumptions described above, and further assuming that (a) all performance-based restricted stock units and stock options will be deemed earned at the maximum level of performance and will vest in full upon a qualifying termination of employment, based on a price per share equal to $51.79; (b) the full value of all equity awards so vesting will be parachute payments; (c) each of the named executive officers receives a prorated annual bonus for the year of termination of employment equal to his or her target annual bonus; (d) the lump sum payment equal to the estimated cost of the Company's medical, dental and vision continuation coverage is $2,200 per month; (e) each named executive officer is subject to the maximum applicable federal and state tax rates in effect for 2022; and (f) none of the parachute payments are exempt under a special rule for reasonable compensation. Any actual entitlement to such additional lump-sum payment will be based on the facts and circumstances that exist at the time of a change in control or a termination of employment in connection with a change in control.

&nbsp;&nbsp;&nbsp;&nbsp;(6)Excise tax gross-up amount for Mr. Daly is calculated with reference to his compensation as a member of our board of directors from 2017-2018, as required by Section 280G of the Code.

**Pay Ratio**

Pursuant to Item 402(u) of Regulation S-K, we are required to disclose in this Proxy Statement the ratio of the annual total compensation of our principal executive officer to the median of the annual total compensation of all of our employees (other than our principal executive officer).

We have determined that Mr. Daly's annual total compensation for fiscal year 2022 was $8,276,720, as disclosed in the 2022 Summary Compensation Table above. Based on SEC rules and guidance and applying the methodology described below, we have determined that the median of the annual compensation, as described below, for all of our employees (other than our principal executive officer) for fiscal year 2022 was $125,450. Accordingly, for fiscal year 2022, we estimate the ratio of our principal executive officer's annual total compensation to the median of the total annual compensation for all of our employees (other than our principal executive officer) was approximately 66 to 1.

We do not believe that any changes to our employee population or compensation arrangements that occurred in fiscal year 2022 would have a significant impact on the pay ratio for fiscal year 2022 and, as a result, we are utilizing the same median employee as used in fiscal year 2021. For purposes of determining our median employee in fiscal year 2021, we selected the last day of our fiscal year, October 1, 2021, to establish our employee population. As of October 1, 2021, our employee population consisted of 1,104 employees, with 778 of these employees employed in the United States, and 326 of these employees employed in 16 other countries throughout the world, primarily in Europe and Asia. As permitted by SEC rules, we excluded 44 employees in following countries under the de minimis exemption for purposes of identifying our median employee: Finland (1), Germany (5), India (30), Italy (1), Singapore (1), South Korea (3), United Kingdom (1) and Vietnam (2). As a result, for purposes of the pay ratio calculation conducted in fiscal year 2021, our employee population consisted of 1,060 employees, with 778 of these employees employed in the United States and 282 of these employees employed outside of the United States.

For purposes of identifying our median employee we used a consistently applied compensation measure consisting of base salary or wages, excluding overtime pay, for the fiscal year ending on October 1, 2021. We annualized the actual base salary or wages paid to those employees who were not employed by us for the entire fiscal year. For employees outside of the United States, we used the foreign exchange rates that were effective as of the last day of our fiscal year to convert the base salaries and wages into U.S. dollars.

The median employee's total annual compensation for fiscal year 2022 was determined using the same rules that apply to reporting the compensation of our named executive officers (including our principal executive officer) in the "Total" column of the 2022 Summary Compensation Table.

This pay ratio is a reasonable estimate calculated in a manner consistent with the SEC's rules and is based on our records and the methodology described above. Because the SEC's rules for identifying the median of the annual total compensation of our employees and calculating the pay ratio based on that employee's annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported above.

| **PROPOSAL 2: ADVISORY VOTE TO APPROVE THE COMPENSATION**  |
| **OF OUR NAMED EXECUTIVE OFFICERS** |

---

Pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we are asking our stockholders to vote to approve, on a nonbinding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement, commonly referred to as the "say-on-pay" vote.

In accordance with Exchange Act requirements, we are providing our stockholders with an opportunity to express their views on our named executive officers' compensation for fiscal year 2022, as disclosed in this Proxy Statement. The Company's current policy is to submit the named executive officers' compensation to an advisory vote at its annual meeting of stockholders every year. Assuming no change to the Company's current policy regarding the frequency of such advisory vote, it is expected that the next "say-on-pay" vote will occur at our 2024 annual meeting of stockholders. Although this advisory vote is nonbinding, our board of directors and compensation committee will review and consider the voting results when making future decisions regarding our named executive officer compensation and related executive compensation programs.

As described in more detail in the Compensation Discussion and Analysis, our executive compensation program is designed to:

 • attract and retain the best executive talent;

 • motivate our executives to achieve our financial and business goals; and

 • align our executives' interests with those of our stockholders to drive increased stockholder value.

We encourage stockholders to read the Compensation Discussion and Analysis beginning on page 20 of this Proxy Statement, which describes the processes our compensation committee used to determine the structure and amounts of the compensation of our named executive officers in fiscal year 2022 and how our executive compensation philosophy, policies and procedures operate and are designed to achieve our compensation objectives. The compensation committee and our board of directors believe that their role is to ensure that our executive compensation strikes the appropriate balance between utilizing measured pay practices and effectively incentivizing our named executive officers to dedicate themselves fully to value creation for our stockholders.

The board of directors recommends that stockholders indicate their support for the compensation of our named executive officers. The vote on this resolution is not intended to address any specific element of compensation but rather the overall named executive officer compensation program as described in this Proxy Statement.

Accordingly, we ask our stockholders to vote on the following resolution at the Annual Meeting:

"RESOLVED, that the stockholders approve, on an advisory basis, the compensation of our named executive officers for fiscal year 2022, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, the compensation tables and any other related disclosure in this Proxy Statement."

**The Board of Directors Recommends a Vote "FOR" the Approval of the Compensation of Our Named Executive Officers.**

We expect that representatives of Deloitte & Touche LLP will be present at the Annual Meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions.

Our board of directors is submitting the appointment of Deloitte & Touche LLP to our stockholders for ratification as a matter of corporate practice. If our stockholders fail to ratify the appointment, the audit committee may reconsider whether to retain Deloitte & Touche LLP. Even if the selection is ratified, the audit committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of us and our stockholders.

The following table provides information regarding the fees billed by Deloitte & Touche LLP for the fiscal years ended September 30, 2022 and October 1, 2021.

| **PROPOSAL 4: APPROVAL OF AN AMENDMENT TO THE COMPANY'S FIFTH AMENDED AND RESTATED CERTIFICAT** |
| **CERTIFICATE OF INCORPORATION TO REFLECT DELAWARE LAW PROVISIONS** |
| **ALLOWING OFFICER EXCULPATION** |

---

**Background** 

The State of Delaware, which is the Company's state of incorporation, recently enacted legislation that enables Delaware corporations to limit the liability of certain of their officers in limited circumstances under Section 102(b)(7) of the Delaware General Corporation Law. Prior to such legislation, Delaware law permitted Delaware corporations to exculpate directors from personal liability for monetary damages associated with breaches of the duty of care, but that protection did not extend to a Delaware corporation's officers. In light of this update, we are proposing to amend the Company's Fifth Amended and Restated Certificate of Incorporation (the "Certificate of Incorporation") to add a provision exculpating certain of the Company's officers from liability in specific circumstances, as permitted by Delaware law.

The proposed Certificate of Amendment to the Certificate of Incorporation ("Certificate of Amendment") reflecting the addition of Article X: Limitation of Officer Liability is attached as Exhibit A to this Proxy Statement (the "Amendment").

**Reasons for the Proposed Amendment**

The new Delaware legislation permits, and the proposed Amendment would permit, exculpation only for direct claims brought by stockholders for breach of an officer's fiduciary duty of care, including class actions, but would not eliminate officers' monetary liability for breach of fiduciary duty claims brought by the corporation itself or for derivative claims brought by stockholders in the name of the corporation. Furthermore, the limitation on liability would not apply to breaches of the duty of loyalty, acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, or any transaction in which the officer derived an improper personal benefit.

Our board of directors desires to amend the Certificate of Incorporation to maintain provisions consistent with the governing statutes contained in the Delaware law and believes that amending the Certificate of Incorporation to add the authorized liability protection for certain officers of the Company, consistent with the protection in the Certificate of Incorporation currently afforded directors of the Company, is necessary in order to attract and retain experienced and qualified officers and would potentially reduce litigation costs associated with frivolous lawsuits. Further, the Company has undertaken in its indemnification agreements with its officers and directors to at all times provide for indemnification and exculpation of officers and directors to the fullest extent permitted under applicable law.

For the reasons stated above, our board of directors unanimously determined that the proposed Amendment is advisable and in the best interest of the Company and its stockholders and authorized and approved the proposed Amendment and directed that it be considered at the Annual Meeting. Our board of directors recommends that the stockholders approve the Amendment.

**Required Vote; Effect of Proposal** 

To be approved, this proposal requires the affirmative vote of a majority of the shares outstanding on the Record Date and entitled to vote on this proposal. Abstentions and broker non-votes will have the same effect as votes against this proposal. If the proposed Amendment is approved by our stockholders, it will become effective immediately upon the filing of the Certificate of Amendment with the Secretary of State of the State of Delaware, which we expect to file promptly after the Annual Meeting. If the proposed Amendment is not approved by our stockholders, our Certificate of Incorporation would remain unchanged.

**The Board of Directors Recommends a Vote "FOR" the Approval of an Amendment to the Company's Fifth Amended and Restated Certificate of Incorporation to Reflect Delaware Law Provisions Allowing Officer Exculpation.**

**AUDIT COMMITTEE REPORT**<br>

The audit committee has reviewed and discussed the audited financial statements for the fiscal year ended September 30, 2022 with our management and Deloitte & Touche LLP, our independent registered public accounting firm. The audit committee discussed with employees of the Company responsible for administering internal audit functions and with the independent registered public accounting firm the overall scope of and plans for their respective audits. The audit committee meets with the employees of the Company responsible for administering internal audit functions and representatives of the independent registered public accounting firm, in regular and executive sessions, to discuss the results of their examinations, the evaluations of the Company's internal controls, and the overall quality of the Company's financial reporting and compliance programs. We also discussed significant accounting policies applied in the Company's financial statements, as well as, when applicable, alternative accounting treatments. Management and the Company's internal and independent auditors also made presentations to the audit committee throughout the year on specific topics of interest, that include but are not limited to: (i) information technology systems, controls and security; (ii) critical accounting policies; (iii) the impact of new accounting guidance; (iv) compliance with internal controls required under Section 404 of the Sarbanes-Oxley Act; (v) compliance with the Company's Code of Business Conduct and Ethics; (vi) risk management initiatives and controls; (vii) significant legal matters; and (viii) insider and related party transactions.

Management is responsible for the preparation, presentation and integrity of the financial statements, accounting and financial reporting principles and internal control over financial reporting and has represented to the audit committee that the consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America. Deloitte & Touche LLP is responsible for (1) performing an independent audit of the financial statements in accordance with the standards of the Public Company Accounting Oversight Board ("PCAOB") and for expressing opinions on the conformity of the financial statements with accounting principles generally accepted in the United States, and (2) performing an independent audit of our internal control over financial reporting statements in accordance with the standards of the PCAOB based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and for expressing an opinion thereon.

The audit committee has discussed with Deloitte & Touche LLP the matters required to be discussed by the applicable requirements of the PCAOB and the SEC, and has received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding the independent auditor's communications with the audit committee concerning independence. The audit committee has discussed with Deloitte & Touche LLP their independence and considered whether Deloitte & Touche LLP's provision of non-audit services to the Company is compatible with the auditor's independence. The audit committee concluded that Deloitte & Touche LLP is independent from the Company and its management.

Based on its reviews and discussions referred to above, the audit committee recommended to the board of directors that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 for filing with the SEC.

Members of the audit committee:

Geoffrey Ribar (Chairman)

John Ritchie

Gil VanLunsen

The Audit Committee Report does not constitute soliciting material, and shall not be deemed to be filed or incorporated by reference into any other Company filing under the Securities Act of 1933, as amended, or the Exchange Act except to the extent that the Company specifically incorporates the Audit Committee Report by reference therein.

The following table presents information as to the beneficial ownership of our common stock as of December 31, 2022 for:

&nbsp;&nbsp;&nbsp;&nbsp;• each person who we know beneficially owns more than 5% of any class of our voting securities;

&nbsp;&nbsp;&nbsp;&nbsp;• each of our current directors or nominees;

&nbsp;&nbsp;&nbsp;&nbsp;• each of our named executive officers named in the Summary Compensation Table above; and

&nbsp;&nbsp;&nbsp;&nbsp;• all of our directors and executive officers as of the end of fiscal year 2022 as a group.

Unless otherwise noted, the address of each beneficial owner listed in the table is c/o MACOM Technology Solutions Holdings, Inc., 100 Chelmsford Street, Lowell, Massachusetts 01851.

We have determined beneficial ownership in accordance with the rules of the SEC. Except as indicated by the footnotes below, we believe, based on the information furnished to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of our common stock that they beneficially own, subject to applicable community property laws.

Applicable percentage ownership is based on 70,733,235 shares of our common stock outstanding as of December 31, 2022. In computing the number of shares of our common stock beneficially owned by a person and the percentage ownership of that person, we deemed outstanding shares of our common stock subject to stock options, restricted stock units or warrants held by that person that are currently exercisable or exercisable (or, in the case of restricted stock units, scheduled to vest and settle) within 60 days of December 31, 2022. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.
