**MACOM TECHNOLOGY SOLUTIONS HOLDINGS, INC.**

**100 Chelmsford Street**

**Lowell, MA 01851**

**PROXY STATEMENT**

**FOR THE 2026 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 2026 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 16, 2026, 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 12, 2026 (the "Record Date").

The Annual Meeting will be held at the Holiday Inn Express, 8 Independence Drive, Chelmsford, Massachusetts 01824, on Thursday, March 5, 2026 at 3:00 p.m. (Eastern Time).

**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 75,010,891 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, Equiniti Capital plc, 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 eight directors nominated by our board of directors and named in the accompanying proxy materials to serve until the 2027 annual meeting of stockholders;

2. An advisory vote approving the compensation of our named executive officers for fiscal year 2025;

&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 October 2, 2026;

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

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

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

**How do I vote?**

*Vote by Internet.* Stockholders of record may submit proxies over the Internet at www.proxyvote.com. Have the Notice of Internet Availability of Proxy Materials in hand when you access the website and follow the steps outlined on the secured website. 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 calling the toll-free number 1-800-690-6903 to transmit your voting instructions. Have the Notice of Internet Availability of Proxy Materials in hand when you access the website and follow the steps outlined on the phone line. 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.

**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 secure website at www.proxyvote.com 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 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. 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.

**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 and 2) 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.

------

**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.

**CORPORATE SUSTAINABILITY AND RELATED POLICIES**<br>

We endeavor to integrate corporate sustainability practices that we believe will create long-term economic value for our stockholders, employees, communities and other constituents.

**Corporate Sustainability**

In fiscal year 2020, we commenced an in depth, multi-year, companywide review of sustainability-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 corporate sustainability steering committee as well as the publication of our annual sustainability reports, beginning in 2021 and continuing through our most recent publication in August 2025. Our corporate sustainability steering committee has responsibility for corporate sustainability matters globally, oversees alignment between our corporate sustainability efforts and our overarching business objectives and reports to the executive leadership and the nominating and governance committee of our board of directors. Our corporate sustainability steering committee includes C-suite executives and senior leaders in Global Operations, Quality, Human Resources, Legal and Compliance, Investor Relations, Finance, Information Security and Data Privacy. We encourage our stockholders to review our 2025 Sustainability Report in full. A summary of the matters contained in our 2025 Sustainability Report are discussed below.

**Corporate Culture and Employee Engagement** 

We are committed to developing a corporate culture that encourages and seeks the betterment of the Company and the communities in which we conduct business. We strive to create a sense of community and well-being that encourages our employees to focus on both their and the Company's long-term success. To foster an innovative, collaborative and employee-centered culture, MACOM conducted an employee engagement survey in February 2025. Our response rate was 88% and included feedback on topics ranging from culture, engagement, development, inclusion and collaboration. 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 are designed to 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 approximately 2,000 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 strive 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 undergo training on and acknowledge receipt of 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 continue 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 approximately 1,900 metric tons per year. We have also installed an additional regenerative thermal oxidizer in our Lowell, Massachusetts manufacturing facility, which destroys volatile organic compounds that could potentially be released from our operations.

------

**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.

**Ongoing Stockholder Outreach Initiatives**

Our board of directors values the opinions of our stockholders in matters related to corporate governance, executive compensation and other matters. We believe that our stockholders strongly support our executive compensation program, as reflected by the approval of, on an advisory basis, the compensation of our named executive officers by 97.3% of the shares voted at our 2025 annual meeting of stockholders. From time to time, we conduct investor outreach involving members of our senior management team and investor relations as well as compensation committee members. This outreach has 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 corporate sustainability program, board composition and corporate governance. Over recent years, we and our board of directors have made numerous changes based, in part, on the feedback we've received. Those changes include, among others, increasing the number of independent members of the board of directors, declassifying our board of directors and appointing a Lead Independent Director.

**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 2025, including telephonic meetings, our board of directors held eight meetings, the audit committee held nine meetings, the compensation committee held five meetings and the nominating and governance committee held five meetings. From time to time during fiscal year 2025, 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 2025, 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. Four of our directors attended our 2025 annual meeting of stockholders held in March 2025.

**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 2025. 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, Ingram, Ribar, Ritchie and Shanmugaraj 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 7, 2026, 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.

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 7, 2026, the composition of our board of directors and its committees satisfied all such requirements.

**Board Leadership Structure**

In November 2023, Stephen Daly, our President and Chief Executive Officer, was elected to serve as the Chair of our board of directors and Peter Chung was elected to serve as our Lead Independent Director.

Our board of directors does not currently have a policy as to whether the offices of Chair of the board of directors and Chief Executive Officer should be separate. Where the Chair and Chief Executive Officer roles are held by the same person, our board of directors appoints an independent director to serve as Lead Independent Director. 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 of Mr. Daly's combined role as Chair and Chief Executive Officer, together with Mr. Chung's role as Lead Independent Director, provides strong independent oversight of management while ensuring clear strategic alignment throughout the Company and allows our board to benefit from Mr. Daly's deep experience, including his prior experience on the board of directors prior to assuming the role of Chief Executive Officer.

**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 corporate sustainability-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 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 and Ritchie and Ms. Rosenband, with Mr. Ritchie 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 and Ritchie 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, Ingram, Ribar and Shanmugaraj, with Mr. Ribar 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 2025 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 considering 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. Ingram, Ritchie and Shanmugaraj and Ms. Rosenband, with Ms. Rosenband 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 corporate sustainability 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 current composition of our Board includes four individuals of Asian ethnicity and two female members. Our goal is to establish and maintain the strongest and most qualified board, while also prioritizing gender, racial and ethnic diversity.

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

(3)Mrs. Ocampo retired from our board of directors effective August 31, 2025.

(4)In connection with her retirement, the board of directors determined to vest Mrs. Ocampo's 2025 restricted stock unit award representing 1,623 shares of our common stock in full as of August 31, 2025.

Our non-employee directors are compensated under our non-employee director compensation policy, which may be amended or updated from time to time, as described below. After reviewing guidance from Pearl Meyer based on its analysis of competitive market and peer company data, effective in March 2024, the compensation committee recommended, and the board of directors approved, updates to our non-employee director compensation policy in order to better align the Company's non-employee director compensation program to those of its peers and to help attract and retain qualified board candidates. Our compensation program for our non-employee directors has two elements: cash compensation and equity-based compensation. No changes were made to our non-employee director compensation policy for fiscal year 2025.

***Cash Compensation*** 

The cash component of our non-employee director compensation program is as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• a $65,000 annual cash retainer for each non-employee director;

&nbsp;&nbsp;&nbsp;&nbsp;• an additional annual cash retainer of $40,000 for the non-employee lead independent director of the board of directors;

&nbsp;&nbsp;&nbsp;&nbsp;• an additional annual cash retainer of $12,500 for each member of the audit committee, $10,000 for each member of the compensation committee and $7,500 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 $25,000 for the chair of the audit committee, $20,000 for the chair of the compensation committee and $15,000 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 calendar year 2025, 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 valued at approximately $190,000 in the aggregate based on the trailing average closing price of the Company's common stock for the fifteen (15) trading days immediately preceding the grant date. 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 valued at approximately $190,000 in the aggregate based on the trailing average closing price of the Company's common stock for the fifteen (15) trading days immediately preceding the grant date, 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 same date which the most recently-granted regular annual awards vest, 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 valued at approximately $170,000 in the aggregate based on the trailing average closing price of the Company's common stock for the fifteen (15) trading days immediately preceding the grant date. This award vests in three equal annual installments on the first three anniversaries of the grant date, 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 7, 2025 we granted each of Messrs. Bland, Chung, Ribar, Ritchie and Shanmugaraj and Mrs. Ocampo and Ms. Rosenband annual restricted stock unit awards representing 1,623 shares of our common stock for his or her service as a director during calendar year 2025, which will, except as set forth below for Mrs. Ocampo, vest in full on March 7, 2026, subject to such non-employee director's continued service through such date and the terms of our 2021 Omnibus Incentive Plan. Pursuant to our director compensation policy, the annual (and, if applicable, initial) 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.

In connection with her retirement, the board of directors determined to vest Mrs. Ocampo's 2025 restricted stock unit award representing 1,623 shares of our common stock in full as of August 31, 2025.

| **NAMED EXECUTIVE OFFICER COMPENSATION,** |
| **COMPENSATION DISCUSSION AND ANALYSIS** |

---

***Named Executive Officers***

This compensation discussion and analysis provides information about our executive compensation programs for fiscal year 2025 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;• Robert Dennehy, Senior Vice President and Chief Operating Officer

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

&nbsp;&nbsp;&nbsp;&nbsp;• Ambra Roth, Senior Vice President, General Counsel 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 2025 were our incentive 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 2025 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 our compensation committee in fiscal year 2025 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 2025, which included companies in the semiconductor, electric components, communications equipment and electronic manufacturing industries. In connection with this review, the compensation committee assessed potential peers based on their relative size, including latest quarterly and trailing twelve months revenue as well as market capitalization as of December 31, 2023 and June 1, 2024, 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 trailing twelve months revenue range of the selected companies varied between $430 million to $4.6 billion, and market capitalization (as of June 1, 2024) varied between $1.4 billion and $35.8 billion. Our relative positioning at the time of assessment was at the 13th percentile of trailing twelve months revenue and the 63rd percentile of market capitalization. Selected peers for fiscal year 2025 consisted of the following companies: Allegro MicroSystems, Inc., Belden Inc., Coherent Corp., Diodes, Inc., IPG Photonics Corp., Lattice Semiconductor Corp., Lumentum Holdings, Inc., MaxLinear, Inc., MKS Instruments, Inc., Monolithic Power Systems, Inc., Power Integrations, Inc., Qorvo, Inc., Semtech Corp., Silicon Laboratories, Inc., Skyworks Solutions, Inc. and Wolfspeed, Inc.

Based on the analysis and guidance provided by Pearl Meyer, including such 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 2024 our compensation committee established fiscal year 2025 total target direct compensation levels for our named executive officers that were above the corresponding levels from fiscal year 2024. 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. Based on our review of the data described above, we believe that the total compensation provided to our named executive officers in fiscal year 2025 was generally slightly below market median to market median in the aggregate, 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 2025 (discussed in more detail below), and market median to above market median in the aggregate, assuming achievement of our maximum performance goals.

***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 2025 was determined by our compensation committee and is intended to reflect each executive's relative level of experience and responsibility.

In fiscal year 2025, the compensation committee approved a 5.2% annual base salary increase for Mr. Daly to better align his base salary with industry peers, a 3.8% annual base salary increase for Mr. Kober, a 10.5% annual base salary increase for Mr. Dennehy based on merit increases and taking into account the continued desire to align compensation with our industry peers, and a 4.7% annual base salary increase for each of Mr. Hwang and Ms. Roth, based, in each case, 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. 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 2025.

**Short-Term Cash Incentives**

Our compensation committee determined the annual target cash incentive opportunities for each of our named executive officers for fiscal year 2025 based on its business judgment regarding the appropriate level of incentive opportunities to motivate and retain our executives, and to establish an appropriate "pay for performance" linkage between their total compensation and our overall financial results. In making this determination, 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 each of our named executive officers for fiscal year 2025, which increased from the level set in fiscal year 2024. The incentive opportunity for our named executive officers was also subject to potential discretionary increase or reduction based on individual performance during the period. Further, the compensation committee maintains the discretion to adjust certain aspects of the Company's short-term cash incentive program from time to time based on the changing nature of the Company's business, the impact of certain special projects and related activities. The following table shows the target annual cash incentive opportunity of each of our named executive officers for fiscal year 2025 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 fiscal year 2022, 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 an effort to balance amounts paid to employees along with stockholder return, we institute short-term cash incentive program caps to limit the upside and/or maximum payouts to our named executive officers. For fiscal year 2025, our named executive officers' bonuses were capped at 200% of their target cash incentive opportunity (or 75% of their target cash incentive opportunity, for the first half of fiscal year 2025).

For fiscal year 2025, 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 at the beginning of 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. Our compensation committee retains the discretion to adjust goals during and following a performance period, including for extraordinary circumstances and non-recurring expenses, and to adjust bonus payouts for each named executive officer based on individual performance during a performance period. 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 generally would align with the target established for each named executive officer, and a maximum amount, which could provide potential upside above the established targets.

After considering the Company's performance relative to prior periods, our compensation committee made a determination to exercise its discretionary authority under the Company's Short Term Cash Incentive Program and cap first half fiscal year 2025 bonuses at 75% of target for all employees, including our named executive officers, as shown in the table below. In April 2025, our compensation committee also determined that for second half fiscal year 2025 bonuses, achievement of target performance would result in payout of 125% of target bonuses, as shown in the table below.

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 the first half of fiscal year 2022 and the first half of fiscal year 2025. The target and maximum performance opportunities were reduced to below 100% for the first half of fiscal year 2025, but the target performance

------

opportunity was increased to above 100% and the maximum performance opportunity remained at 200% for the second half of fiscal year 2025.

(1) None of our named executive officers received a bonus payout for the second half of fiscal years 2024 and 2023.

*First Half Fiscal Year 2025 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 and the achievement of the target or maximum performance goals would result in a payout of one half of 75% of the named executive officer's annual target cash incentive opportunity.

Under the first half fiscal year 2025 program, a total pool for all participating employees Companywide would be funded at approximately $7.3 million for target or for meeting or exceeding maximum performance. Each of Messrs. Daly, Kober, Dennehy and Hwang 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 2025 (see the "Actual Performance" column in the table above), taking into account the compensation committee's determination to exercise its discretionary authority under the Company's Short Term Cash Incentive Program, each named executive officer received a cash incentive payment for the first half of fiscal year 2025 equal to 75% of their first half target level, which was the approved capped payout for 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 2025 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 125% 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 2025 program, a total pool for all participating employees Companywide would be funded at $12.7 million for meeting target performance and $20.0 million for meeting or exceeding maximum performance. Each of Messrs. Daly, Kober, Dennehy and Hwang 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 2025 (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 2025 equal to 132% 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 2025 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 2025 was 103.5% of each executive's respective target annual cash incentive opportunity.

**Long-Term Equity Incentives**

Our fiscal year 2025 long-term equity incentive program was comprised of three components: time-based restricted stock units, Adjusted EPS performance-based restricted stock units and relative total shareholder return ("rTSR") performance-based restricted stock units. In fiscal year 2025, our compensation committee granted to each of Messrs. Daly, Kober, Dennehy, Hwang 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 Messrs. Daly and Kober, approximately 18% of the total value of the award was allocated to time-based restricted stock units and approximately 82% was allocated to performance-based restricted stock units at target level of performance. For Mr. Kober, approximately 19% of the total value of the award was allocated to time-based restricted stock units and approximately 81% was allocated to performance-based restricted stock units at target level of performance. For Mr. Daly, approximately 20% of the total value of the award was allocated to time-based restricted stock units and approximately 80% was allocated to performance-based restricted stock units at target level of performance.

![21881](mtsi-20260116_g15.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 2025, we granted Mr. Daly 17,731 restricted stock units, Mr. Kober 6,549 restricted stock units, Mr. Dennehy 3,979 restricted stock units, Mr. Hwang 3,770 restricted stock units and Ms. Roth 3,770 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, non-cash interest, acquisition and integration related costs, equity investment gains and losses, loss on debt extinguishment, gain on acquired assets, as well as certain tax items, by diluted shares. Adjusted EPS growth was selected as the applicable performance metric for performance-based restricted stock units granted in fiscal year 2025 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 net income and Adjusted EPS is contained in Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on November 6, 2025.

The Adjusted EPS PSUs granted to our named executive officers in fiscal year 2025 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 2025, one tranche eligible to be earned and to vest based on Adjusted EPS growth during fiscal years 2025-2026 and one tranche eligible to be earned and to vest based on Adjusted EPS growth during fiscal years 2025-2027, 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 2.5%), 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 15%) and 300% of the target number of Adjusted EPS PSUs earned if maximum performance is achieved (Adjusted EPS growth of 20%), 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 2025.

The table below sets forth (1) Adjusted EPS growth goals for Adjusted EPS PSUs granted in fiscal year 2025, (2) Adjusted EPS growth goals for Adjusted EPS PSUs granted in previous fiscal years with a performance period that included fiscal year 2025, (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** |
| 2025 | 2025 | 2.5% | 10% | 15% | 20% | 36% | 300% |
| 2024 | 2024-2025 | 2.5% | 10% | 15% | 20% | 13% | 167% |
| 2023 | 2023-2025 | 5% | 10% | 20% | 30% | 7% | 72% |

---

Our Adjusted EPS performance increased in fiscal year 2025 as compared to earlier periods which has resulted in the maximum, above-target and above-threshold payouts, as applicable, being achieved for Adjusted EPS PSUs granted in fiscal year 2025 and prior years.

*Performance-Based Equity Incentives – rTSR PSUs*

Starting 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 2025, we granted Mr. Daly 28,369 restricted stock units, Mr. Kober 11,968 restricted stock units, Mr. Dennehy 8,422 restricted stock units, Mr. Hwang 7,979 restricted stock units and Ms. Roth 7,979 restricted stock units, in each case, subject to the performance-based vesting conditions described below.

The fiscal year 2025 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 September 28, 2024, and ending October 1, 2027. As was the case in 2022, 2023 and 2024, the grant of rTSR PSUs will result in a more significant portion of each executive's fiscal year 2025 compensation being tied to our long-term stock performance as compared to years prior to 2022. 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 and, in each case, with straight-line interpolation between performance levels.

Each of our named executive officers also held rTSR PSUs that were granted in fiscal year 2023 and that were eligible to vest based on rTSR rank for the performance period beginning October 1, 2022 and ending October 3, 2025.

------

The table below sets forth (1) rTSR rank goals for rTSR PSUs granted in fiscal year 2023, (2) our actual rTSR rank for the applicable performance period and (3) the percentage of rTSR PSUs that were earned based on such performance:

---

| | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|
| **Fiscal Year of Grant** | **Performance Period (Fiscal Year(s))** | **Threshold<br>(50% - 100% of Target Number of rTSR PSUs Earned)** | **Target (100% - 200% of Target Number of rTSR PSUs Earned)** | **Maximum<br>(200% of Target Number of rTSR PSUs Earned)** | **Actual Performance** | **% of Target Number of rTSR PSUs Earned** |
| 2023 | 2023-2025 | >25% and ≤ 50% | >50% and ≤ 75% | >75% | 77% | 200% |

---

*Time-Based Equity Incentives*

In fiscal year 2025, 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 2025, we granted Mr. Daly 11,525 RSUs, Mr. Kober 4,366 RSUs, Mr. Dennehy 2,653 RSUs, Mr. Hwang 2,513 RSUs and Ms. Roth 2,513 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 previously 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 policies, 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.

**Policies and Practices Related to the Timing of Equity Grants**

We generally grant annual equity-based awards to our executive officers in the first quarter of each fiscal year, in connection with our annual compensation review and approval process, although the exact timing may change from year to year. The compensation committee and/or our board of directors may also grant equity awards at different times of the year for new hires and in connection with promotions, grants made for retention or for other purposes. Neither the compensation committee nor our board of directors grants equity awards in anticipation of the release of material non-public information and we have not timed the disclosure of material non-public information for the purpose of affecting the value of executive compensation. In fiscal year 2025, equity compensation for our named executive officers consisted solely of RSUs and performance-based restricted stock units; we did not grant stock options to our named executive officers in fiscal year 2025.

**Clawback Policies**

In November 2018, we adopted a clawback policy (the "2018 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 2018 Clawback 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.

In November 2023, we adopted a clawback policy (the "2023 Clawback Policy"), in compliance with the requirements of the Dodd-Frank Act, final SEC rules and applicable Nasdaq listing standards, which covers our current and former officers subject to Section 16 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), including all of our named executive officers. Under the 2023 Clawback Policy, if there is a restatement of our financial results, certain incentive-based compensation paid or awarded to covered employees will be subject to cancellation and/or repayment if the amount of such compensation was calculated based upon the achievement of financial results that were the subject of the restatement and the amount of such compensation that would have been received by the covered employees had the financial results been properly reported would have been lower than the amount actually awarded.

**Accounting Considerations**

Our compensation committee 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, vested stock options, vested stock appreciation rights and unearned performance-based equity awards do not count towards satisfaction of the stock ownership guidelines. Failure to comply with our stock ownership guidelines will (among other things, as may be determined by the compensation committee) require executive officers to retain a portion of the shares of our common stock, net of applicable tax withholding and the payment of any exercise or purchase price (if applicable), received upon the vesting or settlement of equity awards or the exercise of stock options. As of October 3, 2025, all named executive officers are either in compliance with the stock ownership guidelines or within the phase-in period.

**Say-on-Pay**

At our 2025 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 2025 annual meeting of stockholders, our stockholders approved, on an advisory basis, the compensation of our named executive officers by 97.3% of the shares voted.

Our board of directors values the opinions of our stockholders in matters related to corporate governance, executive compensation and other matters. We believe that our stockholders strongly support our executive compensation program, as reflected by the approval, on an advisory basis, described above.

**COMPENSATION COMMITTEE REPORT**

With respect to the Adjusted EPS performance-based restricted stock unit awards granted to our named executive officers during fiscal year 2025, 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 $6,147,515 for Mr. Daly, $2,270,604 for Mr. Kober, $1,379,559 for Mr. Dennehy and $1,307,097 for each of Mr. Hwang and 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 2025, 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 October 3, 2025.

(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 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(1)For stock options, the value realized represents the difference between the closing price of our common stock on the exercise date and the exercise price of the stock option multiplied by the number of shares acquired upon exercise.

&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 2025) 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 2025) 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 October 3, 2025, and based on the closing price of our common stock on this date, $127.41, 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, and twelve months' accelerated vesting credit for any 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 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, as in effect as of October 3, 2025:

&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 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 named executive officers would have received upon the occurrence of these events, assuming that each triggering event occurred on October 3, 2025, 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 2025 reflects the actual bonus earned by Mr. Daly in respect of fiscal year 2025. 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 $2,800 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 October 3, 2025 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 actual annual bonus earned in respect of fiscal year 2025. 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 $2,800 per month for each of Messrs. Daly, Dennehy and Hwang and $3,500 per month for each of Mr. Kober and Ms. Roth.

&nbsp;&nbsp;&nbsp;&nbsp;(3)Amounts are based on the fair market value of our common stock of $127.41 per share, which was the closing price of our common stock on October 3, 2025 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 October 3, 2025 vest in full.

&nbsp;&nbsp;&nbsp;&nbsp;(4)Amounts are based on the fair market value of our common stock of $127.41 per share, which was the closing price of our common stock on October 3, 2025 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 with respect to future fiscal years and will vest in full upon a qualifying termination of employment, based on a price per share equal to $127.41; (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 actual annual bonus earned in respect of fiscal year 2025; (d) the lump sum payment equal to the estimated cost of the Company's medical, dental and vision continuation coverage is $2,800 per month for each of Messrs. Daly, Dennehy and Hwang and $3,500 per month for each of Mr. Kober and Ms. Roth; (e) each named executive officer is subject to the maximum applicable federal and state tax rates in effect for 2025; 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.

**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 ("PEO") to the median of the annual total compensation of all of our employees (other than our PEO).

We have determined that Mr. Daly's annual total compensation for fiscal year 2025 was $10,102,699, as disclosed in the 2025 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 PEO) for fiscal year 2025 was $113,620. Accordingly, for fiscal year 2025, we estimate the ratio of our PEO's annual total compensation to the median of the total annual compensation for all of our employees (other than our PEO) was approximately 89 to 1.

We do not believe that any changes to our employee population or compensation arrangements that occurred in fiscal year 2025 would have a significant impact on the pay ratio for fiscal year 2025 and, as a result, we are utilizing the same median employee as used in fiscal year 2024. For purposes of determining our median employee in fiscal year 2024, we selected the last day of our fiscal year, September 27, 2024, to establish our employee population. As of September 27, 2024, our employee population consisted of 1,728 employees, with 1,245 of these employees employed in the United States, and 483 of these employees employed in 17 other countries throughout the world, primarily in Europe and Asia. As permitted by SEC rules, we excluded 74 employees in the following countries under the de minimis exemption for purposes of identifying our median employee: Finland (4), Germany (7), India (32), Israel (1), Italy (1), Japan (6), South Korea (12), Sweden (4), United Kingdom (1) and Vietnam (6). As a result, for purposes of the pay ratio calculation conducted in fiscal year 2024, our employee population consisted of 1,654 employees, with 1,245 of these employees employed in the United States and 409 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 September 27, 2024. 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 2025 was determined using the same rules that apply to reporting the compensation of our named executive officers (including our PEO) in the "Total" column of the 2025 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.

**Pay Versus Performance**

As required by Item 402(v) of Regulation S-K, the following table and accompanying narrative sets forth information about the relationship between certain financial performance of the Company and executive compensation actually paid ("CAP"), as computed under SEC rules, for our named executive officers ("NEOs") for each of the last five fiscal years. Our compensation committee does not use CAP as a basis for making compensation decisions. See "Named Executive Officer Compensation, Compensation Discussion and Analysis" above for more information about the Company's executive compensation program.

&nbsp;&nbsp;&nbsp;&nbsp;(1)The amounts reported in this column represent the amounts of total compensation reported in the "Total" column of the Summary Compensation Table in each corresponding year for Mr. Daly, who served as our PEO during each of fiscal years 2021, 2022, 2023, 2024 and 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2)The amounts reported in these columns represent the amount of CAP to Mr. Daly and the average amount of CAP to our non-PEO NEOs as a group (set forth in footnote 3 below), as computed in accordance with Item 402(v) of Regulation S-K. The amounts do not reflect the actual amount of compensation earned by or paid to Mr. Daly or our non-PEO NEOs during the applicable year and were not considered by our compensation committee at the time it made decisions with respect to Mr. Daly's or our non-PEO NEOs' compensation. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to total compensation to determine the CAP for fiscal year 2025:

| **Total Adjustments for Equity Awards** | $14242062 | $4273163 |
| **Compensation Actually Paid (as calculated)** | $24344761 | $7556007 |

---

The valuation assumptions used to calculate the fair values of equity awards for purposes of calculating CAP include the stock price as of the applicable measuring date and, in the case of performance-based awards, the probable outcome of the performance conditions as of the applicable measuring date (or actual performance results approved by the compensation committee as of the applicable vesting date). Otherwise, the valuation assumptions used to calculate fair values did not materially differ from those used in our disclosures of fair value as of the grant date. Stock prices as of the measuring dates of October 3, 2025 and September 27, 2024 were $127.41 and $111.52, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(3)The amounts reported in this column represent the average amounts of total compensation reported for our non-PEO NEOs as a group in the "Total" column of the Summary Compensation Table for each corresponding year. The non-PEO NEOs included for purposes of calculating the average amounts in each applicable fiscal year are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 2025 and 2024: Messrs. Kober, Dennehy and Hwang and Ms. Roth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 2023 and 2022: Messrs. Kober, Dennehy and Hwang, Ms. Roth and Dr. Douglas Carlson (who retired from his service with the Company in December 2023); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 2021: Messrs. Kober, Dennehy and Hwang and Ms. Roth.

&nbsp;&nbsp;&nbsp;&nbsp;(4)Cumulative Total Shareholder Return, or TSR, is calculated by dividing the difference between the Company's share price at the end and the beginning of the measurement period by the Company's share price at the beginning of the measurement period, assuming that $100 was invested in the Company's common stock beginning October 2, 2020 (the last trading day in fiscal year 2020). The Company has not paid any dividends since its IPO.

------

&nbsp;&nbsp;&nbsp;&nbsp;(5)Represents the weighted cumulative peer group TSR, weighted according to the respective companies' stock market capitalization at the beginning of each period for which a return is indicated, assuming that $100 was invested beginning October 2, 2020 (the last trading day in fiscal year 2020). The peer group used for this purpose is the PHLX Semiconductor Index. The return of this index is calculated assuming reinvestment of dividends during the period presented. The peer group TSR number for 2023 was revised from the number previously reported in prior years' proxy statements to correct an administrative error in the calculation.

&nbsp;&nbsp;&nbsp;&nbsp;(6)Represents the Company's net income as reported in the Company's audited financial statements.

&nbsp;&nbsp;&nbsp;&nbsp;(7)Adjusted EPS represents net income per diluted share before intangible amortization expense, share-based compensation expense, warrant liability expense, non-cash interest, acquisition and integration related costs, equity method investment gains and losses, debt extinguishment costs and the tax effect of each non-GAAP adjustment. For a discussion of Adjusted EPS and a reconciliation of Adjusted EPS to GAAP net income per diluted share, see Exhibit 99.1 to our Current Report on Form 8-K filed with the SEC on November 6, 2025. In the Company's assessment, Adjusted EPS is the financial performance measure that is the most important financial performance measure used by the Company in fiscal year 2025 to link CAP to the Company's performance.

*Tabular List of Financial Performance Measures*

In our assessment, the most important financial performance measures used to link CAP (as calculated in accordance with the SEC rules), to our NEOs, in fiscal year 2025, to the Company's performance were:

&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted EPS (our Company Selected Measure);

&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted Operating Income; and

&nbsp;&nbsp;&nbsp;&nbsp;• Relative Total Shareholder Return.

As further described above under "Named Executive Officer Compensation, Compensation Discussion and Analysis," our variable compensation includes short-term cash incentives based on achievement of non-GAAP adjusted operating income performance goals, performance-based restricted stock units based on one-, two- and three-year non-GAAP Adjusted EPS growth goals, and performance-based restricted stock units based on our three-year TSR relative to peers.

*Graphical Descriptions of Relationships Between CAP and Certain Financial Performance Measure Results* 

The illustrations below provide a graphical description of CAP (as calculated in accordance with the SEC rules) to our PEO and the average CAP to our non-PEO NEOs in comparison to the following measures, in each case, for the five most recently completed fiscal years:

&nbsp;&nbsp;&nbsp;&nbsp;• (i) the Company's cumulative TSR on $100 invested as of the end of fiscal year 2020 in the Company's common stock, and (ii) the weighted cumulative TSR on $100 invested as of the end of fiscal year 2020 for the PHLX Semiconductor Index;

&nbsp;&nbsp;&nbsp;&nbsp;• the Company's net income; and

&nbsp;&nbsp;&nbsp;&nbsp;• the Company Selected Measure, which is Adjusted EPS.

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

---

Pursuant to Section 14A of 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 2025, 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 2027 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 18 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 2025 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.

Our 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 2025, 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.**

| **PROPOSAL 3: RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP AS OUR** |
| **INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM** |

---

The audit committee has appointed Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending October 2, 2026. Deloitte & Touche LLP has served as our independent public accounting firm since fiscal year 2010. 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 October 3, 2025 and September 27, 2024. All services provided by, and fees paid to, Deloitte & Touche LLP as described below were pre-approved by the audit committee in accordance with the audit committee pre-approval policy set forth below.

**AUDIT COMMITTEE REPORT**<br>

The audit committee has reviewed and discussed the audited financial statements for the fiscal year ended October 3, 2025 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 October 3, 2025 for filing with the SEC.

Members of the audit committee:

John Ritchie (Chair)

Geoffrey Ribar

The following table presents information as to the beneficial ownership of our common stock as of December 31, 2025 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 2025 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 75,010,891 shares of our common stock outstanding as of December 31, 2025. 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, 2025. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

**CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS**<br>

&nbsp;&nbsp;&nbsp;&nbsp;• the amounts involved exceeded or will exceed $120,000; and

&nbsp;&nbsp;&nbsp;&nbsp;• any of our directors, executive officers or beneficial owners of more than 5% of any class of our voting securities, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest.

**Second Amended and Restated Investor Rights Agreement**

We are party to an investors' rights agreement, as amended and restated on February 28, 2012 and further amended on May 20, 2013, February 2, 2015 and June 6, 2018 (the "IRA"), with a group of our stockholders that includes entities affiliated with Mrs. Ocampo, who is a former member of our board of directors and beneficial owner of more than 5% of a class of our voting securities. Subject to the terms and conditions of the IRA, certain stockholders have registration rights with respect to the shares of our capital stock they, or certain of their affiliates, hold, including the right to demand that we file a registration statement or request that their shares be covered by a registration statement that we are otherwise filing.

**Policies and Procedures for Related Person Transactions**

We do not currently have a formal, written policy or procedure for the review and approval of related person transactions. However, our audit committee charter provides that our audit committee is required to review and approve or ratify any related person transactions, as defined under Regulation S-K Item 404. Our Code of Business Conduct and Ethics also prohibits our directors and officers from engaging in a conflict of interest transaction without disclosure to and approval from the board of directors or one of its committees. Each of the related person transactions described above was reviewed and either approved or ratified by our audit committee, and we intend to follow this practice for any future related person transactions.

------

**SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE**<br>

Section 16(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), requires our directors, officers and beneficial holders of more than 10% of a registered class of our equity securities to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock and other equity securities. As a practical matter, we assist our directors and executive officers by monitoring transactions and completing and filing Section 16 reports on their behalf. To our knowledge, based solely on a review of the copies of such reports and written representations from our executive officers and directors that no other reports were required, we believe all required reports under Section 16(a) of the Exchange Act of our directors, executive officers and beneficial holders of more than 10% of a registered class of our equity securities were timely filed since the beginning of fiscal year 2025, other than one late Form 4 filed on November 10, 2025 on behalf of Mrs. Ocampo to report shares sold by Mrs. Ocampo and one late Form 4 filed on December 1, 2025 on behalf of Mr. Dennehy to report RSUs received in connection with his recent promotion, both late filings were due to clerical errors and not timely transmitted to the SEC. The Company has addressed these matters and believes that the errors have been resolved.

**Stockholder Director Nominations and Proposals for Presentation at 2027 Annual Meeting of Stockholders**

For any proposal that is not submitted for inclusion in next year's proxy statement, but is instead sought to be presented directly at the 2027 annual meeting of stockholders, stockholders are advised to review our Bylaws as they contain requirements with respect to advance notice of stockholder proposals not intended for inclusion in our proxy statement and director nominations. To be timely, a stockholder's notice of any director nomination or other proposal of business must be received by our General Counsel at our principal executive offices not less than 45 days or more than 75 days prior to the first anniversary of the date we first mailed our proxy materials or Notice of Internet Availability of Proxy Materials (whichever is earlier) for the prior year's Annual Meeting of Stockholders. Accordingly, any such stockholder's notice of any director nomination or other proposal of business must be received between November 2, 2026 and December 2, 2026. However, in the event that the 2026 annual meeting of stockholders is convened more than 30 days prior to or delayed by more than 30 days after March 5, 2027, notice by the stockholder to be timely must be received not later than the close of business on the later of the 90<sup>th</sup> day prior to such annual meeting or the 10<sup>th</sup> day following the date on which public announcement of the date of the 2027 annual meeting of stockholders is first made. Copies of the pertinent Bylaw provisions are available on request to the following address: General Counsel, MACOM Technology Solutions Holdings, Inc., 100 Chelmsford Street, Lowell, Massachusetts 01851.

In addition to satisfying the deadlines under the advance notice provisions of our Bylaws, a stockholder who intends to solicit proxies in support of director nominees other than the Company's nominees must provide the notice required under Rule 14a-19 under the Exchange Act to our General Counsel at our principal executive offices no later than January 4, 2027 (or, in the event that the 2027 annual meeting of stockholders is convened more than 30 days prior to or delayed by more than 30 days after March 5, 2027, then notice must be provided by the later of 60 days prior to the date of the 2027 annual meeting of stockholders or the 10<sup>th</sup> day following the day on which public announcement of the date of the 2027 annual meeting of stockholders is first made).

As required by our Bylaws, any stockholder submitting a director nomination must include the name, biographical information and other relevant information relating to the recommended director nominee, including, among other things, information that would be required to be included in the proxy statement filed in accordance with applicable rules under the Exchange Act and the written consent of the director nominee to be named as a nominee and to serve as a director if elected, among other requirements set forth in our Bylaws.

**Consideration of Stockholder-Recommended Director Nominees**

Stockholders may contact our board of directors as a group or any individual director by sending written correspondence to the following address: Board of Directors – MACOM Technology Solutions Holdings, Inc., Attn: General Counsel, 100 Chelmsford Street, Lowell, Massachusetts 01851. Stockholders should clearly specify in each communication the name(s) of the group of directors or the individual director to whom the communication is addressed. The General Counsel will review all correspondence and will forward to the board of directors or an individual director a summary of the correspondence received and copies of correspondence that the General Counsel determines requires the attention of the board of directors or such individual director. The board of directors and any individual director may at any time request copies and review all correspondence received by the General Counsel that is intended for the board of directors or such individual director.

**Delivery of Materials to Stockholders with Shared Addresses**

We have adopted a procedure, approved by the SEC, called "householding." Under this procedure, any stockholder, including both stockholders of record and beneficial holders who own their shares through a broker, bank or other nominee, who share an address with another such holder of our common stock are only being sent one Notice of Internet Availability of Proxy Materials or set of proxy materials, unless such holders have provided contrary instructions. Householding helps us reduce printing and postage cost associated with the distribution of proxy materials and helps to preserve natural resources. We will promptly deliver a separate copy of the Notice of Internet Availability of Proxy Materials or set of proxy materials to you upon written or oral request. If you wish to receive a separate copy of these materials or if you are receiving multiple copies and would like to receive a single copy, please contact our investor relations department by phone at (978) 656-2500, or by writing to Investor Relations, MACOM Technology Solutions Holdings, Inc., 100 Chelmsford Street, Lowell, Massachusetts 01851.
