Dear Fellow Cabot Corporation Stockholders,

You are cordially invited to attend the Annual Meeting of Stockholders of Cabot Corporation (the “Company” or “Cabot”), which will be held virtually on Thursday, March 9, 2023, at 4:00 pm, Eastern Time. The Annual Meeting will be held in a virtual meeting format via live webcast at meetnow.global/MRSVEFL, where you will be able to listen to the meeting live, submit questions and vote. You will need your control number included in your Notice of Internet Availability of Proxy Materials or proxy card. There will be no in-person meeting.

At the Annual Meeting, we will ask you to elect four members of our Board of Directors, provide your advisory approval of our executive compensation, provide your advisory vote on the frequency of future executive compensation advisory approvals, and ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending September 30, 2023. We will also discuss any other business matters properly brought before the meeting. The attached proxy statement explains our voting procedures, describes the business we will conduct, and provides information about the Company that you should consider when you vote your shares.

We are using the “Notice and Access” method of providing proxy materials to you via the Internet. We are mailing to you a Notice of Internet Availability of Proxy Materials (the “Notice”) instead of a paper copy of the proxy materials and 2022 Annual Report. Notice and Access provides a convenient and environmentally friendly way for you to access Cabot’s proxy materials. The Notice includes instructions on how to access our proxy statement and our 2022 Annual Report and how to vote your shares. The Notice also contains instructions on how to receive a paper copy of the proxy materials and our 2022 Annual Report, if you prefer.

Your vote is very important to us. Whether or not you plan to attend the Annual Meeting, we encourage you to vote promptly. You may vote by mailing a completed proxy card, by phone or the Internet.

Thank you for your continued support of Cabot Corporation.

Sincerely,

References to “the Company”, “Cabot”, “we”, “us”, and “our” in this proxy statement mean Cabot Corporation.

About the Annual Meeting

Who is soliciting my vote?

The Board of Directors of Cabot Corporation is soliciting your vote at the 2023 Annual Meeting of Stockholders (the “2023 Annual Meeting” or the “meeting”).

What am I voting on?

You are voting on:

• Proposal 1: Election of Juan Enriquez, Sean D. Keohane, William C. Kirby, and Raffiq Nathoo to the class of directors whose term expires in 2026 (see page 18);

• Proposal 2: Advisory approval of our executive compensation (commonly referred to as “say-on-pay”) (see page 66);

• Proposal 3: Advisory approval of whether future executive compensation advisory votes should occur every one, two or three years (see page 67);

• Proposal 4: Ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023 (see page 70); and

• Any other business properly coming before the meeting.

How does the Board recommend that I vote my shares?

The Board’s recommendation can be found with the description of each item in this proxy statement. In summary, the Board recommends that you vote:

• FOR each of the four nominees for director;

• FOR the advisory approval of our executive compensation;

• To hold a say-on-pay vote EVERY YEAR; and

• FOR the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending September 30, 2023.

Who is entitled to vote?

Only stockholders of record at the close of business on January 17, 2023 will be entitled to vote at the 2023 Annual Meeting. As of that date, there were 56,322,146 shares of our common stock outstanding. Each share of common stock is entitled to one vote. There is no cumulative voting.

What is the difference between a stockholder of record and a stockholder who holds stock “in street name”?

If you hold your shares directly in the form of stock certificates or in book-entry form with our transfer agent, Computershare, then you are a “stockholder of record.” If your shares are registered at Computershare in the name of a broker, bank, trustee, nominee or other similar holder of record, your shares are held in “street name.”

CABOT CORPORATION    1

2023 PROXY STATEMENT

The 2023 Annual Meeting is open to all Cabot stockholders entitled to vote at the meeting and their legal proxies by following the instructions below under the heading “How can I attend the 2023 Annual Meeting?” You need not attend the 2023 Annual Meeting to vote.

How can I attend the 2023 Annual Meeting?

The 2023 Annual Meeting will be held in a virtual meeting format via live webcast. There will be no in-person meeting.

2023 PROXY STATEMENT   

About the Annual Meeting (continued)

Why did I receive a “Notice of Internet Availability of Proxy Materials” but no proxy materials?

We are distributing our proxy materials to stockholders via the Internet under the “Notice and Access” approach permitted by rules of the Securities and Exchange Commission (“SEC”). This approach benefits the environment, while providing a timely and convenient method of accessing the materials and voting. On January 26, 2023, we will begin mailing a “Notice of Internet Availability of Proxy Materials” to stockholders, which includes instructions on how to access our proxy statement and our 2022 Annual Report and how to vote your shares. The Notice of Internet Availability of Proxy Materials also contains instructions on how to receive a paper copy of the proxy materials and our 2022 Annual Report, if you prefer.

How many votes must be present to hold the meeting?

Your shares are counted as present at the 2023 Annual Meeting if you attend the meeting or if you properly return a proxy by Internet, telephone or mail. In order for us to hold our meeting, holders of a majority of our outstanding shares of common stock as of January 17, 2023 must be present or represented by proxy at the meeting. This majority is referred to as a quorum. Shares present virtually during the 2023 Annual Meeting will be considered shares of common stock present at the 2023 Annual Meeting. If you are a stockholder of record, your shares are counted as present at the 2023 Annual Meeting if you properly return a proxy by Internet, telephone or mail or if you attend the meeting virtually. If you hold your shares in “street name,” you must follow the instructions of your bank or broker in order to direct them how to vote the shares held in your account or obtain a legal proxy to vote online at the meeting. Proxy cards or broker voting instruction forms that reflect abstentions and broker non-votes will be counted as shares present to determine whether a quorum exists to hold the 2023 Annual Meeting.

What is a broker non-vote?

Under the rules that govern brokers who hold shares in “street name” for their clients who are the beneficial owners of the shares, brokers normally have discretion to vote such shares on routine matters, such as ratifications of independent registered public accounting firms, but not on non-routine matters. Broker non-votes generally occur when the beneficial owner of shares held by a broker does not give the broker voting instructions on a non-routine matter for which the broker lacks discretionary authority to vote the shares. We expect Proposals 1, 2 and 3 will be considered non-routine matters.

Therefore, if your shares are held in “street name” and you do not provide instructions as to how your shares are to be voted on proposals 1, 2 and 3, your broker will not be able to vote your shares on these proposals. We therefore urge you to provide instructions to your broker so that your votes may be counted on these important matters.

How are votes counted? How many votes are needed to approve each of the proposals?

For each of proposals 1, 2, and 4, you may vote “FOR”, “AGAINST”, or “ABSTAIN”. For proposal 3, you may vote to hold a say-on-pay vote once every “ONE”, “TWO” or “THREE” years, or you may “ABSTAIN”.

• Proposal 1 — Election of Directors. Pursuant to our bylaws, a nominee will be elected to the Board of Directors if the votes properly cast “for” his or her election exceed the votes properly cast “against” such nominee’s election. Broker non-votes and abstentions will have no effect on the results of this vote.

• Proposal 2 — Say-on-Pay. Because proposal 2 is an advisory vote, there is no minimum vote requirement that constitutes approval of this proposal.

• Proposal 3 — Frequency of Say-on-Pay Vote. Because proposal 3 is an advisory vote and provides shareholders with multiple voting options, there is no minimum vote requirement that constitutes approval of this proposal.

• Proposal 4 — Ratification of Independent Registered Public Accounting Firm. The affirmative vote of a majority of the votes properly cast on proposal 4 is required to ratify the appointment of Cabot’s independent registered public accounting firm. Brokers generally have discretionary authority to vote on the ratification of our independent registered public accounting firm, thus we do not expect any broker non-votes on this proposal. To the extent there are any broker non-votes, they will have no effect on the results of this vote. Under Delaware law, abstentions are not considered “votes cast” and, therefore, will also have no effect on the results of this vote.

CABOT CORPORATION    3

2023 PROXY STATEMENT   

About the Annual Meeting (continued)

What if there are more votes “AGAINST” a nominee for director than votes “FOR”?

Each of the nominees is an incumbent director who has tendered a conditional resignation that is effective upon (i) the failure to receive a majority of the votes cast for his re-election at the 2023 Annual Meeting and (ii) the Board’s acceptance of this resignation. The Governance and Nominating Committee of the Board of Directors (the “Governance Committee”) would be responsible for initially considering the resignation and making a recommendation to the Board of Directors. The director whose resignation is under consideration is expected to abstain from participating in any decision regarding his resignation. The Governance Committee may consider any factors it deems relevant in deciding whether to accept a director’s resignation. If the resignation is not accepted, the director will continue to serve until his successor is elected and qualified.

How do I vote?

You can vote either online during the meeting or by proxy without attending the meeting. For additional information on how to attend the meeting, please refer to “How can I attend the 2023 Annual Meeting?” above. Even if you plan to attend the 2023 Annual Meeting, we encourage you to vote your shares by proxy. Stockholders of record have three options for submitting their votes by proxy:

1. by Internet – go to www.envisionreports.com/CBT and follow the instructions on the secure site,

2. by phone – call the toll-free number 1-800-652-VOTE and follow the instructions on your proxy card and the recorded telephone instructions, or

3. by mail – mark, sign and date the proxy card and return it promptly in accordance with the voting instructions on your proxy card.

In order for your vote to be counted, you must return your completed and signed proxy card so that it is received by mail by the Company’s transfer agent by March 8, 2023, vote by Internet or by phone until the start of the meeting, or vote at the virtual meeting if you are attending.

If you hold your shares in “street name,” you must follow the instructions of your bank, broker or other nominee in order to direct them how to vote the shares held in your account or obtain a legal proxy to vote online at the meeting. Please follow the directions on your voting instruction form carefully.

How do I vote if I hold my stock through the Cabot 401(k) plan?

The Vanguard Fiduciary Trust Company is the trustee of the Cabot Common Stock Fund and the Cabot Common ESOP Fund portions of the Cabot 401(k) plan and is the record owner of all of those shares. If you hold Cabot stock through the Cabot 401(k) plan, you have the right to instruct Vanguard how to vote your shares. Vanguard will tabulate the voting instructions of each participant in the plan and will vote the shares of all participants by submitting a final proxy card representing the plan’s shares for inclusion in the tally at the 2023 Annual Meeting.

Your vote will influence how Vanguard votes those shares for which no instructions are received from other plan participants as those shares will be voted in the same proportion as shares for which instructions are received. If you hold shares in the plan and do not vote, Vanguard will vote your shares (along with all other shares in the plan for which instructions are not provided) in the same proportion as those shares for which instructions are received from other participants in the plan.

In order for your instructions to be followed, you must provide instructions for the shares you hold through the Cabot 401(k) plan by returning your completed and signed proxy card so that it is received by the Company’s transfer agent by March 6, 2023 or by voting by telephone or over the Internet by 9:00 a.m., Eastern Time, on March 7, 2023.

2023 PROXY STATEMENT   

About the Annual Meeting (continued)

Can I change or revoke my vote?

Yes. You can change or revoke your vote by (1) re-voting by telephone or over the Internet as instructed above (only your latest telephone or Internet vote will be counted), (2) signing and dating a new proxy card or voting instruction form and submitting it as instructed above (only your latest proxy card or voting instruction form will be counted), or (3) attending the meeting and voting online, if you are a stockholder of record or hold your shares in “street name” and have obtained a legal proxy from your bank, broker or other nominee. If your shares are registered in your name, you may also revoke your vote by delivering timely notice to the Secretary, Cabot Corporation, Two Seaport Lane, Suite 1400, Boston, Massachusetts 02210. Attending the meeting will not in and of itself revoke a previously submitted proxy unless you specifically request it. If you hold shares through a bank or broker, you must follow the instructions on your voting instruction form to revoke or change any prior voting instructions.

Who counts the votes?

We have hired Computershare Trust Company, N.A., our transfer agent, to count the votes represented by proxies cast by ballot, telephone and the Internet. A representative of Computershare, Cabot’s Secretary or Cabot’s Assistant Secretary will act as Inspector of Election.

What if I return my proxy card but don’t vote for some of the matters listed?

If you return a signed proxy card without indicating your vote, your shares will be voted in line with the recommendation of the Board of Directors for each of the proposals for which you did not indicate a vote.

Can other matters be decided at the 2023 Annual Meeting?

We are not aware of any other matters that will be considered at the 2023 Annual Meeting. If any other matters properly arise that require a vote, the named proxies will vote in accordance with their best judgment.

What is “householding” and how does it affect me as a stockholder?

Some banks, brokers and other nominee record holders may be participating in the practice of “householding” proxy statements. This means that only one copy of this proxy statement may have been sent to multiple stockholders in the same household. We will promptly deliver a separate copy of this proxy statement to any stockholder upon request to: Secretary, Cabot Corporation, Two Seaport Lane, Suite 1400, Boston, Massachusetts 02210. Any stockholder who wants to receive a separate copy of this proxy statement, or of our proxy statements or annual reports in the future, or any stockholder who is receiving multiple copies and would like to receive only one copy per household, should contact the stockholder’s bank, broker, or other nominee record holder, or the stockholder may contact us at the address and phone number above.

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management

As a leading global specialty and performance materials company, we value integrity, respect, excellence and responsibility. We are committed to living these values every day as they are an integral part of the way we conduct our business. Through our shared purpose — creating materials that improve daily life and enable a more sustainable future — we drive materials innovation, support our customers, and seek to create a more sustainable world. Our strategy articulates how we intend to deliver sustained and attractive total shareholder return, built on earnings growth and a balanced capital allocation framework. In early fiscal 2022 we introduced our Creating for Tomorrow growth strategy following the successful execution of our Advancing the Core strategy, which we had adopted in 2016. Under our Creating for Tomorrow strategy, we have charted a new path for growth and value creation for our Company and intend to leverage our strengths to lead in performance and sustainability. As part of this strategy, we aim: to Grow based on investing for advantaged growth, to Innovate by developing innovative products and processes that enable a better future, and to Optimize by driving continuous improvement in all we do. Our Board is responsible for overseeing the execution of our strategy, and in doing so, the Board seeks to provide leadership as the Company navigates critical issues, including matters related to climate change, diversity, equity and inclusion, a changing regulatory climate, and the evolving nature of information security and cybersecurity threats. The Governance Committee is charged with reviewing the composition of the Board and recommending board refreshment as appropriate so that the Board as a whole reflects a range of talents, skills, diversity and expertise needed to meet the evolving needs of our Company in this changing landscape and to oversee the execution of our strategy.

Important Factors in Assessing Director Qualifications

Director Qualifications. The Governance Committee strives to maintain an engaged, highly skilled, independent board with broad and diverse experience and viewpoints that is committed to representing the interests of our stakeholders. Board candidates as well as nominees for re-election are evaluated in the context of the current composition of the Board of Directors and in relation to the Board’s current and anticipated requirements. We expect our directors and any candidate or nominee to have integrity and to demonstrate high ethical standards. The Committee also considers a wide range of factors when assessing director qualifications, including:

Ensuring an experienced, qualified Board with expertise in areas relevant to Cabot. The Committee seeks directors who have held significant leadership positions and can bring to the Board specific types of experience relevant to Cabot. It is the Board’s policy that the Board as a whole reflect a range of talents, skills and expertise, particularly in these areas:

• Management Leadership and Strategic Planning Experience. We believe that directors who have held significant leadership positions over an extended period of time possess strong leadership qualities and demonstrate a practical understanding of organizations, processes, strategy and risk management and know how to drive change and growth. As a publicly traded company, we value experience on the boards of other publicly traded companies and other complex organizations.

• Specialty Chemicals or Adjacent Industry and Operations Experience. We seek directors with leadership, operational and risk management experience in specialty chemicals or adjacent industries and the value chains in which we operate, as well as experience addressing environmental issues and sustainability considerations.

• Global Experience. We value directors with global business experience because we have significant global manufacturing operations, and, as in recent years, a majority of our revenues came from outside of the U.S. in fiscal 2022.

• Accounting and Finance Experience. We use a broad set of financial metrics to measure our performance, and accurate financial reporting and robust auditing are critical to our success.

• Technology and Market Experience. As an innovative science and technology company, we value directors with an understanding of technology, material science and the value chains in which we participate. Under our “Creating for Tomorrow” strategy, we believe this is critical as we seek to grow by developing new products and identifying new applications and high-growth markets for our materials.

6    CABOT CORPORATION

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

Enhancing the Board’s diversity of background. As a global company, diversity is an essential element of our culture. At the Board level and throughout our Company we value the benefits received from different perspectives, and strive for a talented and diverse workforce and Board that is representative of our global business, customers, employees and stockholders. In evaluating the suitability of individual Board nominees, the Governance Committee considers many factors, including general understanding of the disciplines relevant to the success of a publicly traded company with global manufacturing operations in today’s business environment, professional experience, background, education, skill, age, race, gender and national origin. Our Corporate Governance Guidelines include diversity of origin, gender, background, experience and thought as important director selection criteria and, as a result, we do not have a separate formal written policy that solely addresses diversity. In addition, given the value of gender and ethnic diversity to our Board, these criteria are important elements in the Board’s new director searches. Approximately half of our current directors have joined our Board over the last five years, and among these directors we have further enhanced the Board’s gender and ethnic diversity with two new women directors, one of whom is also ethnically diverse, as well as one other new ethnically diverse director. In total, 30% of our current independent directors are women and 30% are ethnically diverse. The Governance Committee reviews its effectiveness in balancing these considerations when assessing the composition of the Board.

Individual Attributes. The Board believes that to function effectively, all directors should demonstrate sound judgment, compassion, and a willingness and ability to work with other members of the Board openly and constructively. In addition, they should have the ability to communicate clearly and persuasively, while dedicating sufficient time to ensure the diligent performance of their duties on our behalf.

Complying with the Board’s independence guidelines. When selecting and recruiting candidates, the Board looks at other positions the candidate has held or holds, including other board memberships, as well as the candidate’s other relationships, to determine whether any material relationship with Cabot exists that could impair the candidate’s independence.

CABOT CORPORATION    7

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

As highlighted in the graphics below, we believe the Board as a whole possesses a balanced mix of the talents, skills, diversity, expertise, tenure and independence needed to meet the evolving needs of the Company and to oversee the execution of our “Creating for Tomorrow” strategy. More details on each director’s qualifications and expertise are included in the director biographies on the following pages.

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

Our Board’s Role in Risk Oversight and in Overseeing our Progression on Environmental, Social and Governance (“ESG”) Matters and Activities

Our Board oversees our enterprise-wide program of risk management. Cabot management is primarily responsible for day-to-day risk management practices and, together with other personnel, annually engages in an enterprise-wide risk assessment. This assessment includes a comprehensive review of a broad range of risks, including financial, operational, business, legal, regulatory, reputational, governance and managerial risks that may affect the Company. From this assessment, the most significant risks in terms of their likelihood and severity are identified and plans to manage and mitigate these risks are developed. During calendar year 2022, we enhanced our risk management practices for ESG matters and established a management ESG Steering Committee (the “ESG Steering Committee”), which is composed of the members of our Management Executive Committee and chaired by our CEO. Separate subcommittees that report to the ESG Steering Committee have been established with specific responsibilities related to environmental, social and governance matters as set out in their subcommittee charters, and are resourced by teams across our Company and chaired by one or more members of our Management Executive Committee. The ESG Steering Committee will meet twice a year at the Management Executive Committee’s offsite strategy and business meetings, and more frequently as deemed appropriate. Cabot management regularly reports to either the full Board or the relevant Committee of the Board our major risk exposures, their potential operational or financial impact on Cabot, and the steps we take to manage them. The Company has a robust risk management program, the strength of which, we believe, is not dependent on the Board’s leadership structure.

Our Board has ultimate responsibility for risk oversight and oversees our corporate strategy, business development, capital structure and country-specific risks. This includes business continuity risks, including climate-related risks, that have been identified as having a material impact on our business, strategy or operations. Each Committee also has responsibility for risk oversight within their areas of responsibility and expertise.

Our Board Committee structure assists the Board in fulfilling its oversight responsibility and provides for risk oversight as follows:

• Audit Committee — focuses on financial risk, including internal controls and legal and compliance risks and receives regular reports from our independent registered public accounting firm, our CFO, our Controller, our Treasurer, our Director of Internal Audit, our Chief Digital Information Officer and our General Counsel. The Audit Committee also oversees the Company’s enterprise risk management processes and cybersecurity program, and management annually reviews our information security and cybersecurity program with the full Board.

• SHE&S Committee — reviews the effectiveness of our safety, health, environment and sustainability (“SHE&S”) programs and initiatives and oversees matters related to stewardship and sustainability of our products and manufacturing processes. The Committee also focuses on issues around climate change, technological innovation, and the evolving regulatory landscape that affect our manufacturing operations.

• Compensation Committee — considers human resources risks and evaluates and sets compensation programs that encourage decision-making predicated upon a level of risk consistent with our business strategy. The Committee reviews gender-based pay equity globally and pay equity among our employees in the United States based on racial/ethnic diversity.

• Governance Committee — considers governance and Board and CEO succession risks and evaluates director skills and qualifications.

More information describing our Board Committees, their responsibilities, and specific areas of risk oversight is below under the heading “How Our Board Operates”.

As reflected in our “Creating for Tomorrow” strategy, we are committed to operating responsibly, reducing our environmental impact and developing innovative performance materials that address the sustainability challenges of our customers, communities and the world. We therefore work to incorporate environmental sustainability, employee safety and well-being, diversity, equity and inclusion and other values into our decision-making in a manner that we believe will both mitigate risk and drive long-term value.

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

In fiscal 2020, we adopted our 2025 Sustainability Goals to further articulate our commitment to ESG matters and facilitate the integration of this commitment into the operation of our business. These goals address 11 topics that we have identified as important to Cabot and are categorized under the following three pillars: Caring for our People and Communities, Acting Responsibly for the Planet, and Building a Better Future Together. Our work to achieve each of these goals is resourced by teams across our Company and each goal is sponsored by a member of our Management Executive Committee. With respect to Board oversight of ESG matters in general, rather than concentrating oversight of all ESG initiatives into any one Committee, the Board takes the approach that certain matters are most appropriately overseen by the Board as a whole and, for other topics, the most appropriate Committee should maintain oversight. The graphic below provides an overview of Board and SHE&S Committee oversight with respect to each of our three pillars.

	Caring for our People and Communities		Acting Responsibly for the Planet		Building a Better Future Together
Our entire Board reviews talent management and management succession planning, as well as the Company’s diversity and inclusion objectives and achievements. The SHE&S Committee oversees our goals related to community engagement and occupational health and safety.		The SHE&S Committee focuses on issues around climate change and the evolving regulatory landscape, and oversees our goals related to emissions, energy, wastes and spills, water, and environmental compliance.		The entire Board has oversight of Cabot’s goals that address product sustainability, suppliers’ sustain ability, and economic value gen erated and distributed.

To further advance our sustainability agenda, we have committed to align our climate-related disclosures with the recommendations of the Task Force for Climate-related Financial Disclosure (“TCFD”), and, based on the work we have done to date, we disclosed our preliminary analysis in a climate scenario risks and opportunities matrix developed in accordance with the TCFD guidance. In addition, at the beginning of fiscal 2022, we announced our ambition to align our sustainability agenda with the Paris Climate Agreement to achieve net zero carbon emissions globally by 2050. We believe our activities related to these matters will be most appropriately overseen by the Board as a whole, and that our SHE&S Committee should allocate significant time annually for discussion of these matters.

Information on our sustainability goals, our Climate Scenario Risks and Opportunities Matrix, and the various ESG-related awards we have received is available on our website at www.cabotcorp.com/sustainability, which information is not part of, or incorporated by reference into, this proxy statement.

In addition, to reinforce the Company’s commitment to developing a more inclusive and diverse organization, the Compensation Committee oversaw management’s development of diversity, equity, and inclusion (“DE&I”) objectives and metrics for the portion of the 2023 corporate short-term incentive compensation awards payable on the basis of participant individual performance.

Assessment of Risk in Incentive Compensation Program

Our Compensation Discussion and Analysis (“CD&A”) describes our compensation policies, programs and practices for our named executive officers. The corporate goal-setting, assessment and compensation decision-making processes described in our CD&A apply to all participants in our corporate short- and long-term incentive programs.

Participants in our long-term incentive program receive awards consisting of time-based restricted stock units and performance-based restricted stock units and, in the case of members of the Management Executive Committee and a

limited number of other participants, stock options. In addition to our corporate short- and long-term incentive programs, during fiscal 2022 we also maintained a cash incentive plan for certain functional and business roles and our manufacturing facilities offered an annual cash incentive plan.

The Compensation Committee directed management, working with the Committee’s independent consultant, Meridian Compensation Partners, to provide an evaluation of the design of these incentive plans to assess whether any portion of our incentive compensation programs encourages excessive risk taking. That assessment was presented to and reviewed by the Compensation Committee. Among the program features evaluated were the types of compensation offered, the types and mix of performance metrics, the alignment between performance goals, payout curves and the Company’s business strategy, and the overall mix of incentive awards. The Company’s compensation programs are designed with features intended to mitigate risk without diminishing the incentive nature of the program. Specific features of the programs intended to mitigate risk include, as applicable, the following: caps limiting the amount that can be paid under the corporate short- and long-term incentive programs and all of the non-corporate cash incentive programs; a balanced mix of annual and longer-term incentive opportunities; a mix of cash and equity incentives; multiple performance metrics; management processes to oversee risk associated with each of our incentive programs; stock ownership guidelines for members of the Management Executive Committee; a company compensation recoupment policy; and significant controls for important business decisions. In our CD&A we describe in more detail the features of our executive compensation programs that are designed to mitigate risk, including the oversight provided by the Compensation Committee, which reviews and approves the design, goals and payouts under our corporate short- and long-term incentive programs and each executive officer’s compensation. Based on our assessment, we believe our compensation policies, programs and practices do not create risks that are reasonably likely to have a material adverse effect on the Company.

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

Our Leadership Structure — Non-Executive Chair of the Board; Executive Sessions

Sue H. Rataj has served as Non-Executive Chair of the Board of Directors since March 9, 2018.

Although our Corporate Governance Guidelines do not require that our Chair and Chief Executive Officer positions be separate, our Board believes that this leadership structure is appropriate at this time because it allows our Chief Executive Officer to focus on the strategic and operational aspects of our business, while allowing the Non-Executive Chair of the Board to provide independent leadership for the Board. Our Board recognizes that future circumstances may lead it to change the leadership structure depending on Cabot’s needs at the time and, as such, believes that it is important to retain flexibility. In the future, if the Chief Executive Officer also serves as Chair of the Board, our Corporate Governance Guidelines require that an independent director be appointed annually as lead director to set the agenda for and lead the executive sessions of the non-management directors at Board meetings and to undertake such other responsibilities as the independent directors designate.

Key Responsibilities. Our Non-Executive Chair of the Board focuses on the Board’s processes and ensuring it is prioritizing the right matters. Specifically, the Chair has the following responsibilities, and may perform other functions at the Board’s request:

• presiding over meetings of our Board and stockholders, including executive sessions of the non-management directors;

• serving as an ex-officio member of each Board committee of which he or she is not a member and, upon invitation, attending those committee meetings where possible;

• establishing an agenda for each Board meeting in collaboration with our CEO and meeting with our CEO following each meeting to discuss any open issues and follow-up items;

• facilitating and coordinating communication among the non-management directors and our CEO and an open flow of information between management and our Board;

• leading our Board’s annual performance review in collaboration with the Governance Committee;

• meeting with each non-management director at least annually;

• providing assistance to our CEO by attending selected internal business management meetings and meeting with our CEO as necessary;

• coordinating the periodic review of management’s strategic plan;

• leading our Board’s review of the succession plans for our CEO in collaboration with the Governance Committee; and

• working with management on effective stockholder communication and engagement.

How Our Board Operates

Our Board of Directors has six scheduled Board meetings to review and discuss Cabot’s performance and prospects, with calls and communications between meetings as appropriate. The Board interacts directly with senior management during its meetings. The Board typically dedicates one multiple-day meeting a year to a discussion of longer-term strategic matters. During fiscal 2022, the principal focus of this meeting was the Company’s growth strategy and sustainability agenda. Two other areas of particular focus during fiscal 2022 and for which the Board invited outside experts to participate in a broad Board discussion, were (i) geo-political and business risk to multi-national corporations doing business in China, and (ii) cybersecurity, including the evolving nature of cybersecurity risks, regulatory developments in the area, and leading practices in cybersecurity risk governance and Board oversight. During fiscal 2022, the Board met six times and acted by written consent once.

A significant portion of the Board’s oversight responsibility is carried out through its four operating committees.

Committee Composition. All of the members of our Audit Committee, Governance and Nominating Committee, Safety, Health, Environment and Sustainability Committee and Compensation Committee satisfy the NYSE’s definition of an independent director.

Committee Operations. Each Committee meets periodically throughout the year, reports its actions to the Board, receives reports from senior management, annually evaluates its performance and can retain outside advisors. Each Committee’s meeting materials are available for review by all directors.

Executive Committee

Members

Sue H. Rataj, Chair	Michael M. Morrow
Sean D. Keohane

No meetings in fiscal 2022

Corporate Governance Guidelines

Our Board of Directors has adopted Corporate Governance Guidelines that address director qualifications (which include the Board’s policy on director overboarding) and independence, Board Committees, director compensation, Board performance evaluations, Board and Committee meetings, access to senior management, and Chief Executive Officer performance evaluation and succession planning, among other matters. Many of the Board’s practices and policies set out in these Guidelines are described throughout this discussion of Board Leadership, Governance and Composition and Risk Management. The Corporate Governance Guidelines are posted on our website (www.cabotcorp.com) under the heading “Company — About Cabot – Governance – Resources.”

CABOT CORPORATION    15

2023 PROXY STATEMENT   

Board Leadership, Governance and Composition, and Risk Management (continued)

How We Assess Director Independence

The Board’s Guidelines. Under our Corporate Governance Guidelines, it is the Board’s policy that at least the majority of the Board’s members must be independent. The Governance Committee annually reviews the independence of all directors and reports its findings to the full Board. All of our current directors are “independent” under the Board’s director independence standards, other than Mr. Keohane, our President and CEO. For a director to be considered independent, the Board must determine that he or she does not have any material relationship with Cabot. The Board’s guidelines for director independence are consistent with the independence requirements in the New York Stock Exchange’s listing standards. The Board evaluates all relevant facts and circumstances in making an independence determination. In assessing director independence, the Board considers all known relationships, transactions and arrangements among directors, their family members, and Cabot. The Board concluded that none of the non-management directors who served as directors during the 2022 fiscal year had a material relationship with Cabot.

How We Evaluate Our Board and Assess Director Recommendations

Each year, the Governance Committee leads our Board’s annual evaluation process. The process focuses on the effectiveness of the Board as a whole, prioritizing issues, and identifying specific matters for future discussion. For 2022, our General Counsel solicited feedback from each director based on a series of questions covering Board and Committee membership, operations and responsibilities, as well as open-ended questions so that each director had leeway to provide feedback on the issues he or she believed to be the most pertinent. In addition, our Non-Executive Chair conducted one-on-one discussions with each director, during which she also sought feedback on individual director performance from other directors. The key themes, observations and suggestions with respect to the Board’s performance as a whole were summarized and discussed with the full Board. Based on these discussions, opportunities to further enhance the Board’s effectiveness have been and are being implemented.

Board Refreshment. A number of changes have occurred in our Company’s Board of Directors over the past several years as part of our continuing efforts to ensure that our Board has the right skills and tenures to best oversee management and the execution of our strategy and the associated risks. Approximately 20% of our directors have joined the Board within the last three years and approximately 50% of our directors have joined within the last five years. Our Board does not have a mandatory retirement policy because the Board is of the view that a mix of tenures that takes into consideration appropriate levels of continuity, institutional memory and fresh perspectives is critical in achieving and maintaining a high-performing board. The Board will continue to proactively manage its composition and make-up to ensure it has the appropriate mix of tenures, diversity, and the requisite skills to address the Company’s current and future needs.

Candidate Recommendations. We identify candidates for election to the Board of Directors through the business networks of the directors and management and from recommendations made by third-party search firms upon the request of the Governance Committee. In fiscal 2022, the Governance Committee retained a search firm to help identify potential candidates with specific skills and professional experience identified by the Committee as important as it considers Board succession planning, as well as potential candidates whose membership on our Board would continue to enhance the Board’s gender and ethnic diversity. Mr. Nathoo was initially identified as a candidate for election to the Board by a third-party search firm, and upon the recommendation of the Governance Committee, the Board elected Mr. Nathoo a director effective May 2022. In considering Mr. Nathoo’s candidacy, the Board considered Mr. Nathoo’s significant leadership experience, his international financial and capital markets expertise, both as an investor and as an M&A advisor, and his broad strategic perspective. In addition, Mr. Nathoo has further enhanced the diversity of our Board. We evaluate candidates recommended by our stockholders in the same manner and on the same basis as candidates recommended by our directors, management or third-party search firms.

Procedures for Stockholders to Recommend Director Nominees

The Governance Committee has a policy with respect to the submission of recommendations by stockholders of candidates for director nominees, which is available on our website at www.cabotcorp.com under the heading “Company— About Cabot—Governance—Resources”. A stockholder wishing to recommend a candidate must submit the recom-

mendation by a date no later than the 120^th calendar day before the first anniversary of the date that Cabot released its proxy statement to stockholders in connection with the previous year’s annual meeting. Recommendations should be submitted to the Company’s Secretary in writing at Cabot Corporation, Two Seaport Lane, Suite 1400, Boston, Massachusetts 02210. The notice to the Secretary should include all information about the candidate that Cabot would be required to disclose in a proxy statement in accordance with Securities and Exchange Act rules or as required by the Company’s by-laws, consent of the candidate to serve on the Board of Directors, if nominated and elected, and agreement of the candidate to complete, upon request, questionnaires customary for Cabot directors and to comply with applicable Company policies.

Proposal 1 — Election of Directors

Board of Directors

Our Board of Directors currently has eleven members and is divided into three classes serving staggered three-year terms. Directors for each class are elected at the annual meeting of stockholders held in the year in which the term for their class expires. Four directors are proposed to be elected at the 2023 Annual Meeting. The terms of Juan Enriquez, Sean D. Keohane, William C. Kirby, and Raffiq Nathoo expire at the 2023 Annual Meeting and our Board of Directors has nominated each of them for a three-year term that will expire at the annual meeting in 2026. All of them are current directors and, with the exception of Mr. Nathoo, have been elected by stockholders at previous annual meetings.

We expect that all of the nominees will be available for election, but if any of the nominees are not available at the time of the 2023 Annual Meeting, proxies received will be voted for substitute nominees to be designated by the Board of Directors or, if no substitute nominees are identified by the Board, proxies will be voted for a lesser number of nominees. In no event will the proxies be voted for more than four nominees.

Vote Required

A nominee will be elected to the Board of Directors if the votes properly cast “for” his election exceed the votes properly cast “against” such nominee’s election. Abstentions and broker non-votes will have no effect on the results of this vote.

Recommendation

The Board of Directors recommends that you vote “FOR” the election of its four nominees.

Other Governance Policies and Practices

Transactions with Related Persons

Policy and Procedures for the Review of Related Person Transactions

Our Board has adopted a written policy for the review and approval of transactions involving related persons. “Related persons” consist of any person who is or was (since the beginning of the fiscal year) a director, nominee for director or executive officer of Cabot, any greater than 5% stockholder of Cabot and the immediate family members of any of those persons. The Governance Committee is responsible for applying the policy with the assistance of our General Counsel.

Transactions covered by the policy consist of any transaction, arrangement or relationship (including any indebtedness or guarantee of indebtedness) or any series of similar transactions, arrangements, or relationships in which (1) the aggregate amount involved will or may be expected to exceed $120,000 with respect to any fiscal year, (2) Cabot is a participant and (3) any related person has or will have a direct or indirect interest, other than solely as a result of being a director or a less than 10% beneficial owner of another entity (an “interested transaction”). Under the policy, the following interested transactions have a standing pre-approval from the Governance Committee, even if the aggregate amount is greater than $120,000:

• Certain sales of stock by executive officers to Cabot. (1) Sales of Cabot stock by an executive officer (including the CEO) to Cabot pursuant to the terms of our long-term incentive program or (2) other sales by executive officers (excluding the CEO) provided that the sale has been approved by our CEO, the per share purchase price is the fair market value of our common stock on the date of sale, the proceeds from the sale to the executive officer do not exceed $500,000, and the sale does not take place during a quarterly blackout period.

• Certain transactions with other companies. Any transaction between Cabot and another company if the aggregate amount involved does not exceed the greater of $1,000,000 or 2% of that company’s total revenues. This pre-approval applies if the related person’s only relationship is as an employee (other than executive officer), director or beneficial owner of less than 10% of the other company’s shares.

• Employment of executive officers; director compensation. Any employment by Cabot of an executive officer if the related compensation is required to be reported in our proxy statement or if the compensation was approved by our Compensation Committee. Any compensation paid to a director if the compensation is required to be reported in our proxy statement.

• Other transactions. Competitively bid or regulated public utility services transactions; transactions involving trustee-type services; and transactions where the related person’s interest arises solely from the ownership of our common stock and all common stockholders received the same benefit on a pro rata basis.

Each interested transaction by a related person that does not have standing pre-approval under the policy should be reported to our General Counsel for presentation to the Governance Committee for approval before its consummation. The Chair of the Governance Committee has the authority to pre-approve or ratify (as applicable) any interested transaction with a related person in which the aggregate amount involved is expected to be less than $500,000. In determining whether to approve or ratify an interested transaction, the Governance Committee and the Chair may take into account such factors as they deem appropriate, which may include whether the interested transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction.

Transactions with Related Persons

Since the beginning of fiscal 2022, Cabot and its subsidiaries had no transactions, nor are there any currently proposed transactions, in which Cabot or its subsidiaries was or is to be a participant and the amount involved exceeds $120,000 and any related person (as defined above) had or will have a direct or indirect material interest reportable under SEC rules.

Other Governance Policies and Practices (continued)

Stockholder Engagement

The Company welcomes stockholder engagement. Our directors are available to answer questions from stockholders at the 2023 Annual Meeting. In addition, management of the Company conducts stockholder outreach throughout the year to ensure management and the Board understand and consider the issues that matter most to our stockholders. We provide regular updates regarding the Company’s performance and strategic actions to the investor community, and we participate in numerous investor conferences, one-on-one meetings, earnings calls, investor days, and educational investor and analyst conversations. Consistent with this practice, in fiscal 2022 we hosted an investor day, during which Mr. Keohane, our CEO, and other members of our executive team provided an in-depth review of our updated growth strategy and financial targets. We also communicate with stockholders and other stakeholders through various media, including our annual report, proxy statement and other filings with the SEC, news releases and our website. We believe ongoing stockholder engagement allows us to respond effectively to stockholder concerns.

Director Attendance at Meetings

During fiscal 2022, each director attended at least 75% of the aggregate of the total Board meetings and the total meetings held by all of the Committees on which he or she served during the periods that he or she served. The 2022 Annual Meeting was held in a virtual meeting format by live webcast and each of our Directors attended and were available to respond to questions.

Code of Business Ethics and Training

We have adopted a code of ethics that applies to all of our employees and directors, including the Chief Executive Officer, the Chief Financial Officer, the Controller and other senior financial officers. In fiscal 2022, each of our directors completed our Code of Business Ethics on-line compliance training program that we require our employees to complete. In addition, in fiscal 2022, as part of our risk oversight of our information technology systems and risk mitigation efforts, employee training on cybersecurity risks was required of all Cabot employees who have access to our information technology resources. The Code of Business Ethics is posted on our website (www.cabotcorp.com) under the caption “Company —About Cabot — Code of Business Ethics.”

Communications with the Board

Stockholders or other interested parties wishing to communicate with the Board, the non-management directors or any individual director may contact the Non-Executive Chair of the Board by calling 1-800-853-7602; or by sending an email through our website using the link that is located under the caption “Company — About Cabot — Governance — Contact the Board of Directors”.

Anyone who has a complaint or concern regarding our accounting, internal accounting controls or auditing matters may communicate that concern to the Chair of the Audit Committee by calling 1-800-853-7602; or by sending an email through our website using the link that is located under the caption “Company — About Cabot — Governance — Contact the Board of Directors”. All such communications to the Board of Directors or the Audit Committee will also be sent to Cabot’s Office of Compliance.

2023 PROXY STATEMENT   

Director Compensation

Annual compensation for our non-employee directors is comprised of cash compensation and a grant of Cabot common stock. The Governance Committee is responsible for reviewing the form and amount of compensation paid to our non-employee directors and recommends changes to our Board of Directors as appropriate. In November 2021, the Governance Committee, with the assistance of Meridian, a national executive compensation firm, evaluated the competitiveness of the Company’s director compensation program, which included a review of director compensation data from the same peer group of companies our Compensation Committee uses for assessing its executive compensation decisions. Based on this evaluation and upon the recommendation of the Governance Committee, our Board of Directors approved changes to our non-employee director compensation program as follows: effective January 1, 2022, we (i) increased the annual retainer from $90,000 to $95,000; (ii) increased the annual retainers paid to the Chairs of the SHE&S Committee and the Governance Committee from $10,000 to $15,000; (iii) reinstated the payment of the $15,000 annual retainer paid to the Chair of the Governance Committee when the Chair of that Committee is also serving as Non-Executive Chair of the Board; and (iv) increased the annual retainer paid to the Non-Executive Chair of the Board from $110,000 to $120,000. Directors who are Cabot employees do not receive compensation for their services as directors.

Cash Compensation

With the changes described above, effective January 1, 2022, annual cash compensation for our non-employee directors consists of the following components:

• $95,000 retainer

• $20,000 for serving as Chair of the Audit Committee

• $15,000 for serving as Chair of the Compensation Committee

• $15,000 for serving as Chair of the SHE&S Committee

• $15,000 for serving as Chair of the Governance & Nominating Committee

• $120,000 for serving as Non-Executive Chair of the Board of Directors

Cash compensation is paid quarterly and, when changes occur in Board or Committee membership during a quarter, the compensation is pro-rated.

Stock Compensation

Under the Cabot Corporation 2015 Directors’ Stock Compensation Plan (the “Directors’ Stock Plan”), each non-employee director is eligible to receive each calendar year shares of Cabot common stock as part of his or her compensation for services to be performed in that year. For calendar year 2022, each non-employee director who was serving as a director at the time the awards were granted in January received an award of shares having a grant date value as close as possible to $135,000 (2,254 shares). The closing price of our common stock on January 13, 2022, the date such shares were granted, was $59.87. Upon his election to the Board, effective May 12, 2022, Mr. Nathoo received an award of shares having a grant date value as close as possible to $84,380 (1,291 shares) as compensation for his services as a non-employee director to be performed in calendar year 2022. The closing price of our common stock on May 12, 2022 was $65.36. For calendar year 2023, each non-employee director received an award of shares having a grant date value as close as possible to $135,000 (1,854 shares).

As of January 17, 2023, there were 174,174 shares available for issuance under the Directors’ Stock Plan.

We believe that it is desirable for our directors to have an equity interest in Cabot and we encourage all directors to own a reasonable amount of Cabot stock to align director and stockholder interests and to enhance a director’s long-term perspective. Accordingly, our Corporate Governance Guidelines require non-employee directors to have an equity ownership in Cabot in an amount equal to five times the annual cash retainer paid for service as a director. It is expected that this ownership level will generally be achieved within a five-year period beginning when a director is first elected to the Board. For purposes of determining a director’s compliance with this ownership requirement, any deferred shares

CABOT CORPORATION    27

2023 PROXY STATEMENT   

Director Compensation (continued)

held by a director are considered owned by the director. In addition, each non-employee director is required to retain the shares granted in any given year for a period of at least three years from the date of issuance or until the director’s earlier retirement.

Reimbursement of Certain Expenses

Our Corporate Governance Guidelines state that Cabot will not provide retirement or other benefits or perquisites to non-employee directors. Directors, however, are reimbursed for reasonable travel and out-of-pocket expenses incurred in connection with attending Board and Committee meetings and other Cabot business-related events and are covered by Cabot’s travel accident insurance policy for such travel.

Deferred Compensation

Under the Cabot Corporation Non-Employee Directors’ Deferral Plan (the “Deferred Compensation Plan”), directors can elect to defer receipt of any cash compensation payable in a calendar year for a period of at least three years or until they cease to be members of the Board of Directors. In any year, these deferred amounts are, at the director’s choice, either (i) credited with interest at a rate equal to the Moody’s Corporate Bond Rate for the month of November prior to the beginning of the applicable year or (ii) treated as invested in Cabot phantom stock units, based on the market price of shares of Cabot common stock at the time of deferral (with dividends paid on shares credited and treated as if reinvested in Cabot phantom stock units). Messrs. Del Grosso, Enriquez and Nathoo and Dr. Wolfgruber elected to defer receipt of their calendar years 2021 and 2022 cash compensation, as applicable, and treat the deferred amounts as invested in Cabot phantom stock units. Mr. Kirby elected to defer receipt of his calendar years 2021 and 2022 cash compensation and have it credited with interest at a rate equal to the Moody’s Corporate Bond Rate. The Moody’s Corporate Bond Rate used to calculate interest during calendar year 2022 was 2.96%.

Under the Deferred Compensation Plan, directors also may defer receipt of the shares of common stock issuable to them under the Directors’ Stock Plan. For each share of stock deferred, a director is credited with one Cabot phantom stock unit to a notional account created in the director’s name. Dividends that would otherwise be payable on the deferred shares accrue in the account and are credited with interest at a rate equal to the Moody’s Corporate Bond Rate for the month of November prior to the beginning of the year. The rate used to calculate interest during calendar year 2022 was 2.96%. At the end of the deferral period, the deferred shares of Cabot common stock are issued to the director, along with the accrued cash dividends and interest earned, either in one issuance or in installments over a period of up to ten years, as selected by the director. Messrs. Del Grosso, Enriquez, Kirby, Morrow, Nathoo, and Wilson, Ms. Yan, and Drs. Arnold and Wolfgruber elected to defer their calendar year 2022 stock awards.

Highlights of our Fiscal Year 2022 Named Executive Officer Compensation Decisions and the Impact of Company Performance on Compensation.

We believe fiscal 2022 compensation appropriately aligned our named executive officers’ compensation with our corporate performance, with a significant portion of the compensation paid to our named executive officers based on our performance against pre-established corporate financial goals. Specifically, 65% of the total direct compensation opportunity for our CEO (base salary, target short-term incentive (“STI”) award and long-term incentive (“LTI”) awards (with performance-based restricted stock units (“PSUs”) valued at target)) was performance-based and not guaranteed, and, on average, the percentage of total direct compensation opportunities for our other named executive officers that was performance-based was 56%. The charts below show the total direct compensation opportunities provided to our named executive officers for fiscal 2022, as well as the mix between short- and long-term compensation, noting the elements that constitute performance-based compensation.

Base Salary. All of our named executive officers, with the exception of Mr. Keohane, whose base salary was determined to be competitive by the Committee based on a review of benchmark compensation data and the Committee’s targeting strategy for executive compensation, as described below, received a base salary increase for calendar 2022 during our annual salary review process that took place in November 2021. The Compensation Committee approved merit-based salary increases for each of our named executive officers (other than Mr. Keohane) ranging from 3.0% to 4.5% for 2022, and a market-based adjustment for Ms. Kalita of 3.5%, as further described below. The increases in the base salaries of our named executive officers during the annual review process were made in recognition of the officers’ strong individual performance and leadership, and, in the case of Ms. Kalita, to bring her base salary closer to the market median of the benchmark compensation data used by the Committee, as further described below. With these increases, we believe the base salaries of our named executive officers for fiscal 2022 were aligned and consistent with our com-

Executive Compensation (continued)

pensation philosophy, which considers individual performance and leadership, scope of responsibilities, the number of years the executive has held the position, and benchmark compensation data to arrive at a market competitive base level of compensation appropriate for the individual. (See pages 46-49 for further details).

STI Awards and Payouts. Under our STI program, 70% of each award is based on the achievement of pre-established corporate financial goals and the remaining 30% of each award is based on individual performance and achievements. The corporate financial goals established for each metric under this plan and our actual performance with respect to each such metric are presented below. Based on this performance, payout with respect to the corporate financial goals portion of the fiscal 2022 STI was 147.2% of target.

* Non-GAAP financial measure. See Appendix A.

The balance of the amounts paid with respect to STI awards to our named executive officers reflected their individual performance and demonstrated leadership and ranged from 125% to 150% of target. The total STI awards made to our named executive officers ranged from 141% to 148% of the named executive officer’s target award. (See pages 46-49 for further details about awards and payouts made to our named executive officers). We believe these STI awards were well aligned with our outstanding fiscal 2022 financial performance, consistent with the role of these awards in advancing our pay-for-performance philosophy.

LTI Awards and Payouts. Our LTI program is 70% performance-based and 30% time-based, consisting of a combination of PSUs (35%), stock options (35%) and time-based restricted stock units (“TSUs”) (30%) (with percentages measured based on the awards’ grant date values, assuming target level achievement of applicable performance goals in the case of PSUs). The grant date value of the awards granted in fiscal 2022 to each named executive officer was based on an assessment of the named executive officer’s position, role and responsibilities within the Company, the overall competitiveness of his or her total direct compensation, and internal equity (the relationship of pay among the executive officers in the context of their responsibilities) and retention considerations. (See pages 46-49 for further details.)

Executive Compensation (continued)

Further, as described on page 43, each PSU award is allocated evenly into three tranches, with each tranche having a separate fiscal year performance period and the entire award having a cumulative three-year overall vesting period. All performance goals for each performance period are established at the time of grant to cover the full three-year performance period. Our financial performance in each fiscal year determines the percentage of the target award earned for that fiscal year performance period in three outstanding PSU awards. The percentage of the target awards earned for fiscal 2022 performance with respect to outstanding PSUs is set forth below. For each performance metric, adjusted EPS and adjusted RONA, achieving the target level of performance results in 100% of the portion of the award that relates to that metric being earned. We believe that the PSUs earned based on our fiscal 2022 financial results properly aligned our LTI compensation with our outstanding fiscal 2022 financial performance, consistent with the role that these awards have in advancing our pay-for-performance philosophy.

Consideration of Results of Shareholder Advisory Votes on Executive Compensation

At our 2022 Annual Meeting, we conducted an advisory (non-binding) shareholder vote on executive compensation, as required by the Dodd-Frank Act. 96.13% of the shares voted approved the executive compensation discussed and disclosed in the Compensation Discussion and Analysis, the Summary Compensation Table and other related tabular and narrative disclosures contained in our 2022 proxy statement. In considering the results of this most recent favorable advisory vote on executive compensation, among other things, the Compensation Committee determined that the Company’s executive compensation programs have been effective in implementing the Company’s stated compensation philosophy and objectives, and directly aligning compensation paid or earned with Company performance and the performance of our stock. Therefore, the Committee did not make any changes in the structure of these programs or in response to this vote.

The Compensation Committee recognizes that executive pay practices and corporate governance principles continue to evolve. Accordingly, it will continue to monitor executive compensation practices and make adjustments as necessary to ensure that our executive compensation programs continue to support our corporate goals and objectives, appropriately incentivize management and reflect good corporate governance principles.

The Compensation Committee pays close attention to the advice of its compensation advisors and provides access for our shareholders who would like to communicate on executive compensation directly with the Compensation Committee or the Board. You may contact the Board of Directors through our website at “Company — About Cabot — Governance — Contact the Board of Directors”.

Compensation Philosophy, Objectives and Process

Continuing to position Cabot for future success requires the talent to support our business and strategy. Our executive compensation programs are designed to provide a competitive and internally equitable compensation and benefits package that incentivizes and rewards individual and Company performance and reflects job complexity and the strategic value of the individual’s position while also promoting long-term retention. We seek to accomplish these goals in a way that is aligned with the long-term interests of our shareholders.

To achieve these goals, our executive compensation programs adhere to these principles:

• Offer a total compensation opportunity and a benefits package that are competitive in our industry;

• Reward executives based on our business performance by closely aligning a majority portion of their compensation with the performance of the Company on both a short- and long-term basis;

• Set challenging performance goals that support the Company’s short- and long-term financial goals;

• Motivate individual performance by rewarding the specific performance and achievements of individual executives and their demonstrated leadership; and

• Align the interests of our executives and our shareholders through performance-based compensation, equity grants and stock ownership guidelines.

Our Compensation Setting Process

The Compensation Committee

As discussed under “Board Leadership, Governance and Composition, and Risk Management — How Our Board Operates — Compensation Committee”, on page 13, the Compensation Committee is responsible for all compensation decisions related to members of the Company’s Management Executive Committee, which includes all our named executive officers.

The annual compensation planning process for the preceding fiscal year concludes at the Committee’s meeting in November, when the Committee evaluates the Company’s performance against the corporate performance goals set for the just-concluded fiscal year and also evaluates each executive officer’s individual performance and, on this basis, determines the amounts payable or earned, as applicable, in the fiscal year under our STI and LTI programs. Each November, the Compensation Committee also (i) determines any adjustments to base salaries, with any adjustment

CABOT CORPORATION    37

2023 PROXY STATEMENT   

Executive Compensation (continued)

typically effective the following January, (ii) sets corporate performance metrics applicable to our STI and LTI programs for the current fiscal year, (iii) grants LTI awards, and (iv) establishes performance goals and maximum payout levels under our STI and LTI programs for awards granted in the current fiscal year, in each case, for each named executive officer.

A description of the Compensation Committee’s roles and responsibilities is set forth in its written charter adopted by the Board of Directors, which can be found at www.cabotcorp.com under “Company — About Cabot — Governance — Resources.”

Role of the Compensation Consultant

The Compensation Committee has retained Meridian Compensation Partners (“Meridian”) as its independent compensation consultant for purposes of advising on executive compensation matters since March 2018. During fiscal 2022, Meridian provided the Committee with advice on a broad range of executive compensation matters, including the following:

• Apprising the Committee of compensation-related trends and developments in the marketplace;

• Informing the Committee of regulatory developments relating to executive compensation practices;

• Reviewing and assessing the composition of the group of peer companies used for compensation benchmarking purposes;

• Providing the Committee with an assessment of the market competitiveness of our executive compensation programs;

• Assessing the relationship between executive compensation actually paid and corporate performance;

• Identifying potential changes to our executive compensation programs to maintain market competitiveness and consistency with business strategies, good governance practices and alignment with shareholder interests; and

• Reviewing the disclosure of our executive compensation programs in this proxy statement.

Meridian attended all regularly scheduled meetings of the Compensation Committee during fiscal 2022.

The Compensation Committee has assessed the independence of Meridian pursuant to SEC rules and concluded that no conflict of interest exists that prevents Meridian from independently advising the Compensation Committee.

Role of the Chief Executive Officer and Other Officers

Each year, our CEO and our Chief Human Resources Officer (“CHRO”), working with internal resources as well as Meridian, review the design of our executive compensation programs and recommend modifications to existing, and/or the adoption of new, plans and programs to the Compensation Committee. In addition, our CEO recommends to the Committee the performance metrics and goals to be used to determine future payouts under our STI and LTI programs, and each named executive officer’s individual performance goals (other than the CEO’s) are jointly developed by the executive and the CEO.

Before the Compensation Committee makes compensation decisions regarding the compensation of our named executive officers, the CEO provides his assessment of each named executive officer’s performance, other than his own, taking into consideration factors such as the officer’s achievement of individual goals, leadership accomplishments, contribution to Cabot’s performance and the achievement of Company goals, and areas of strength and areas for development. He then makes specific award recommendations for these officers. In preparing compensation recommendations for the Committee, our CEO, our CHRO and other members of management involved in the process review compensation and survey data compiled by the Committee’s independent compensation consultant for similarly-situated executives at our peer group of companies and other external competitive market data provided by such consultant, as described below. Our CEO attends Compensation Committee meetings but is not present for, and does not participate in, any discussions concerning his own compensation. All decisions relating to the compensation of our named executive officers are made solely by the Committee and are reported to the full Board of Directors.

Use of Benchmarking Comparison Data

Our fiscal 2022 compensation peer group consisted of companies in the diversified chemicals or specialty chemicals industries with similar products and services and with revenues and a market capitalization generally between one-third

38    CABOT CORPORATION

2023 PROXY STATEMENT   

Executive Compensation (continued)

and three times the Company’s revenue and market capitalization. The Compensation Committee reviews executive compensation data for executives with comparable positions at these peer group companies to gauge the reasonableness of its executive compensation decisions and the competitiveness of our executive compensation programs. The Compensation Committee believes maintaining market-competitive executive compensation programs allows us to successfully attract and retain experienced executives who are critical to our long-term success.

The Compensation Committee annually reviews the companies included in our compensation peer group and may add or eliminate companies as it determines to be appropriate. For purposes of fiscal 2022 compensation matters our compensation peer group consisted of the following 22 companies:

•  Albemarle Corporation •  Ashland Global Holdings, Inc. •  Avient Corporation (formerly PolyOne Corporation) •  Axalta Coating Systems •  Celanese Corporation •  The Chemours Company •  Element Solutions, Inc. (formerly Platform Specialty Products Corporation) •  FMC Corporation •  Ferro Corporation •  H.B. Fuller Company •  Huntsman Corporation •  Innospec Inc. •  Kraton Corporation •  Minerals Technologies •  NewMarket Corporation •  Olin Corporation •  Orion Engineered Carbons S.A. •  RPM International Inc. •  Stepan Company •  Trinseo S.A. •  Tronox Limited •  W.R. Grace & Co.

In preparation for the fiscal 2023 executive compensation review season and the decisions that the Compensation Committee has made and will make with respect to fiscal 2023 compensation, the Compensation Committee reviewed, with Meridian, the peer group companies listed above and confirmed the appropriateness of the peer group, with the exception of Kraton Corporation and W.R. Grace & Co., which were removed following their acquisitions, for benchmarking the Company’s executive compensation programs.

The Compensation Committee and management also consider executive compensation survey data when evaluating the compensation of our named executive officers. The survey data used is based on information reported in the Willis Towers Watson Executive Compensation survey.

Each year, the Compensation Committee reviews tally sheets that detail all elements of each named executive officer’s compensation and benefits for the current and prior fiscal years, as well as a projection of his or her compensation for the upcoming fiscal year. These are provided to the Committee as a means to review the total compensation and benefits package for each named executive officer and the impact of any compensation decisions on such compensation and benefits levels.

Factors Considered in Determining Amounts of Compensation

The Compensation Committee considers the following factors in determining each named executive officer’s total annual and long-term compensation opportunities:

• the officer’s role, level of responsibility, performance, demonstrated leadership, and experience;

• the number of years the officer has held his or her position;

• the current target total compensation for each officer;

• employee retention and internal equity considerations; and

• external competitiveness.

The Compensation Committee has adopted a targeting strategy for executive compensation decisions that defines competitiveness as a “range around the market 50^th percentile” for total direct compensation as a whole (base salary, target STI awards and LTI awards (with PSUs valued at target)). For members of the Management Executive Committee who are promoted from within Cabot and whose total direct compensation is not competitive at the time of their

CABOT CORPORATION    39

2023 PROXY STATEMENT   

Executive Compensation (continued)

promotion under our targeting strategy, our philosophy and intention is to bring such executive’s total direct compensation to within the median competitive range of the benchmark compensation data used by the Committee over a three-year period from the time of their promotion, subject to actual performance in the role. The Committee believes that the use of a range provides the Committee with the framework to target the market median of the benchmarking data used by the Committee, as described under “Use of Benchmarking Comparison Data” above, but to vary compensation opportunities as it deems appropriate based on individual and Company circumstances.

Developing Company Performance Metrics

The five financial performance metrics we used for our STI and LTI programs in fiscal 2022 are intended to support our short- and long-term business plans and strategies. Our philosophy in setting goals for each of the financial metrics under our STI and LTI awards is to set challenging target goals that, in addition to promoting well-rounded Company and management performance:

• drive achievement of our strategy to improve our profitability and achieve our adjusted EPS compound annual growth rate goal (which is 8-12% over time under our Creating for Tomorrow strategy), and manage our cash flow; and

• will be realized as a result of strong execution by management and Company performance.

For our STI awards we used three financial metrics that align with our business strategy to determine the amount earned with respect to such awards. Adjusted EBIT was the principal financial performance metric under this plan because it reflects an important near-term goal of improving our operating profitability and is a key driver of TSR. To increase the focus on efficiently managing our working capital, and to measure our short-term financial health, we used a net working capital (“NWC”) days metric, and to incentivize cash flow management, we used discretionary free cash flow (“DFCF”) as the third financial metric. Adjusted EBIT had a weighting of 60%, and NWC days and DFCF each had a weighting of 20%.

For our PSU awards, we used adjusted EPS as the principal financial performance metric because it reflects an important longer-term financial goal of improving our after-tax profitability and it reflects the depreciation burden of capital investments made to drive long-term earnings growth. Because our business is capital intensive, we believed it was also appropriate to include a return metric under our LTI program and, as a result, used adjusted return on net assets (“RONA”), which measures how effectively and efficiently we use our operating assets to generate earnings. For awards made for fiscal 2021 and thereafter, we modified the weighting of these two financial metrics. For PSUs granted before November 2020, adjusted EPS and adjusted RONA had an 80% and 20% weighting, respectively. For awards granted in November 2020 (during fiscal 2021) and in November 2021 (during fiscal 2022), adjusted EPS and adjusted RONA have a 65% and 35% weighting, respectively. Placing a more significant emphasis on the adjusted RONA performance metric is intended to further incentivize the importance of capital efficiency and the effective and efficient use of our operating assets to generate earnings.

When setting financial targets, typically we begin with our performance in the just completed fiscal year and set growth targets from that base that align with the execution of our strategy. Accordingly, in setting our adjusted EBIT and adjusted EPS goals for fiscal 2022, we began with our performance in fiscal 2021 and set a growth target based on that performance. In setting adjusted EPS targets, we set targets over the three-year term of the PSU awards that would result in payouts based on our strategic long-term goal of achieving an 8-12% earnings per share compound annual growth rate over time. In setting NWC and DFCF targets, our goals in 2022 were to maintain and continue to build on the structural and process improvements we had made in recent years, and in setting adjusted RONA targets, we sought to drive earnings growth at return levels greater than our weighted average cost of capital. We recognize that from time to time we may need to change the metrics we use to reflect new priorities and business circumstances and we expect to continue to reassess our performance metrics and goal setting process annually.

Our Performance-based Compensation Philosophy

How Did our Fiscal 2022 STI Program Operate?

We provide annual STI awards to drive the achievement of key short-term business results and to recognize individuals based on their contributions to those results and Cabot’s overall performance. Each named executive officer has an annual target incentive opportunity under our STI program, which is expressed as a percentage of his or her base salary, as summarized below:

Name	FY22 STI Target			FY22 STI Target  Amount
Sean D. Keohane		120	%	$	1,242,000
Erica McLaughlin		75	%	$	411,334
Karen A. Kalita		65	%	$	300,307
Hobart C. Kalkstein		70	%	$	364,980
Jeff Zhu		70	%	$	364,855

The actual amounts payable under the STI program range from 0% to 200% of the target award opportunity, with 70% of each award based on the achievement of pre-established corporate financial goals and the remaining 30% of each award based on individual performance and achievements. The Committee established threshold, target, and maximum performance level goals for each financial metric: adjusted EBIT, NWC days, and DFCF, with payout for performance between performance levels determined on a straight-line basis. For NWC days and DFCF, the target levels utilized a narrow “dead band” of days and a cash flow range, respectively, so that small variations around demonstrated performance levels on these metrics would not be rewarded or penalized. Under our STI program, the Committee retains the discretion, after determining the amount that would otherwise be payable under an award for a performance period, to adjust the actual payment, if any, to be made under such award. Consistent with prior years, the Committee did not exercise such discretion with respect to fiscal 2022 awards.

At the beginning of each fiscal year, the non-Executive Chair, with input from the other independent directors, develops the individual performance goals for our CEO, which are then approved by the Committee. Each of our other executive officers develops with the CEO his or her individual performance goals for the year. In assessing each executive officer’s individual performance, the Committee considers the officer’s personal achievements, including his or her achievement against these pre-established individual performance goals, as well as individual contributions to the management team and to the Company, and leadership and management of the executive officer’s business, region or function, as applicable. The Committee does not assign specific numerical weightings or ratings to the individual performance goals and the performance of each officer is evaluated as a whole. Furthermore, there are no formal threshold levels of achievement applicable to the individual performance component of our STI program. Ultimately, the determination of the payout of the portion of the STI awards based on individual performance is based on the judgment of the Committee (with respect to our CEO) and our CEO and the Committee (with respect to our CEO’s direct reports), in each case, after reviewing all relevant factors, with the final determination made by the Committee.

* Non-GAAP financial measure. See Appendix A.

** Payout range at target level performance for DFCF is 95% to 105% of target.

The portion of the STI award that was earned by each named executive officer based on individual performance reflected his or her individual performance and leadership in fiscal 2022 (ranging from 125% to 150% of target), with the total STI awards earned ranging from 141% to 148% of the named executive officer’s overall target award. Detailed information about each named executive officer’s fiscal 2022 STI payout is set forth in the discussion below under the heading “Fiscal 2022 Compensation Decisions”.

How Did our Fiscal 2022 LTI Program Operate?

We provide our named executive officers with LTI awards to incentivize sustainable growth and long-term value creation, to further align the interests of our executives with those of our shareholders by tying the executives’ realized compensation to stock price changes during the performance and/or vesting periods, and to promote retention. The grant date value of LTI awards granted to each named executive officer for a given year is based on an assessment of the individual’s position, role and responsibilities within the Company, the overall competitiveness of his or her total direct compensation opportunity, and internal equity considerations. The Committee also considers compensation peer group and other market data for a general understanding of competitive equity compensation practices and considers the impact of the grants on equity incentive plan usage and share dilution, as well as the Company’s compensation expense and employee retention concerns.

70% of the target value of our executives’ LTI awards is performance-based, consisting of a combination of PSUs and stock options, which only provide value when our share price increases above the share price on the date of grant. When making LTI awards for fiscal 2022, the Compensation Committee first determined the total grant date value of the awards to be granted to each executive, and then delivered that value in three components: PSUs representing 35%,

42    CABOT CORPORATION

2023 PROXY STATEMENT   

Executive Compensation (continued)

stock options representing 35%, and TSUs representing 30%, respectively, of the total grant date value of the award, assuming target level achievement of applicable performance goals for PSUs. The terms of each type of LTI award are described in further detail below. These terms are generally applicable to LTI awards granted in fiscal 2022 and in previous fiscal years.

PSUs reward performance and the execution of our goal to deliver year-over-year and long-term growth in earnings and to increase the operating profit we generate relative to the capital we invest in our businesses. Stock options are performance-based because no value is created unless the value of our common stock appreciates after grant, and they encourage employee retention through the use of a time-based vesting schedule. TSUs encourage employee retention by providing some level of value to executives who remain employed for three years. PSUs, stock options and TSUs also support an ownership culture and thereby encourage our executives to take actions that are best for Cabot’s long-term success. Importantly, although each of these equity awards provides a competitive economic value on the date of grant, their ultimate value to an executive will depend upon the degree to which we achieve objectively measurable performance metrics and/or the market value of our common stock after the end of the relevant vesting period. That value will be largely dependent upon our performance and the performance of our stock.

PSUs

To reinforce the long-term nature of the PSU awards and to reward performance and the execution of our long-term growth goals, at the time of grant, the performance metrics and goals for each of the three one-year performance periods of the award are established. Specifically, each award of PSUs is allocated evenly into three tranches, with each tranche having a one-year performance period and the entire award having a three-year vesting period. When the award vests at the end of the applicable three-year period, the number of shares of stock issuable, if any, will depend on the degree of achievement of corporate performance goals for each year within the overall three-year performance period. Based on the degree to which we achieve the performance goals, an executive may earn between 0% to 200% of the target number of PSUs allocated to each tranche of his or her award.

To drive long-term performance, threshold, target and maximum goals are established for the corporate performance metrics for each tranche in the three-year performance period at or before the time of grant of the PSUs. In November 2019 and November 2020, at the time it approved the grant of PSU awards for fiscal 2020 and fiscal 2021, respectively, the Committee established the specific performance metrics and goals for the fiscal 2020, fiscal 2021, fiscal 2022 and fiscal 2023 performance periods of these awards, as applicable, based on our strategic goal at that time of achieving a 7-10% earnings per share compound annual growth rate over time and taking into account an expected gradual recovery and expansion over the three-year period from the COVID-19 pandemic-related performance levels experienced in fiscal 2020. In November 2021, at the time it approved the grant of PSU awards for fiscal 2022, the Committee established the specific performance metrics and goals for the fiscal 2022, fiscal 2023 and fiscal 2024 performance periods of these awards based on our strategic long-term goal of achieving an 8-12% earnings per share compound annual growth rate over time.

2023 PROXY STATEMENT   

Executive Compensation (continued)

Setting metrics and goals for each performance period at the time of grant of the PSUs serves to both reinforce the long-term nature of these awards and to incentivize our executive officers to achieve incrementally more challenging goals for each fiscal year included in the award. Our actual performance against those goals determines the number of shares that will be issued in respect of the PSUs when the awards vest, with the number of shares issued for performance between performance levels interpolated on a straight-line basis.

To reinforce the cash management goals under our corporate strategy, dividend equivalent payments are made in cash in respect of PSUs that are earned based on the achievement of applicable performance metrics, but that have not vested based on time, when and if dividends are declared and paid on the Company’s common stock. The objective of providing such dividend equivalent payments is to help focus our executives on, and to reward them for, managing the business to produce cash that is capable of being distributed to shareholders in the form of a dividend. Dividend equivalents also mirror the income generation associated with stock ownership.

Stock options

Stock options are granted with an exercise price equal to 100% of the closing price of Cabot’s common stock on the date of grant. They generally vest, subject to continued employment, over a three-year period (30% on each of the first and second anniversaries of the date of grant and 40% on the third anniversary of the date of grant) and have a ten-year term.

TSUs

TSUs generally vest, subject to continued employment, in their entirety at the end of three years. When the TSUs vest, they are settled in shares of Cabot common stock. During the vesting period, dividend equivalents are paid in cash on each TSU when and if dividends are declared and paid on the Company’s common stock for the reasons described above under “PSUs”.

Practices Regarding the Grant of Equity Awards

Annual equity grants are made at the Compensation Committee’s regularly scheduled meeting in November to align the timing of grants with our fiscal year, most importantly for PSUs, which are earned based on a fiscal year performance period. The exercise price of stock options is the closing price of Cabot stock on the NYSE on the date the options are granted. From time to time, equity awards outside of the annual grant program are made for recruiting or retention purposes or in connection with promotions or to recognize specific achievements or performance. We do not have a program, plan, or practice to time “off-cycle” awards in coordination with the release of material non-public information.

PSUs Earned under Outstanding PSU Awards on the Basis of Fiscal 2022 Performance

The following tables show the performance metrics and goals and the relative weighting of each metric that the Committee set for the fiscal 2022 performance period of PSUs granted in fiscal 2020, 2021, and 2022, our degree of attainment of these goals and the percentage of the awards earned, measured against the target award. Because the performance metrics and goals for the fiscal 2022 performance period of these awards were established at different times based on when they were granted, they each reflect the long-term goals and target-setting philosophy in place when they were awarded.

ESG-related Objectives included in 2023 STI Program

To reinforce the Company’s commitment to integrate sustainability throughout Cabot and develop a more inclusive and diverse organization, for the 2023 STI program, management has developed DE&I objectives and metrics for the portion of STI awards that is based on individual performance and achievements. These objectives are to: (i) demonstrate improvement in the percent of job searches in which diverse candidates are interviewed; (ii) ensure strong pay equity is maintained with action plans to address any pay inequity identified through the Company’s global compensation review process; and (iii) require all managers to attend inclusive leadership training. In assessing each named executive officer’s individual performance when determining amounts payable under STI awards on this basis, achievement against these goals by the Company as a whole with respect to Mr. Keohane, and with respect to the business or function each other named executive officer manages, will be considered.

Risk Assessment

We monitor the risks associated with our executive compensation programs and policies on an on-going basis. In May 2022, management presented the Committee with the results of a study it conducted of our compensation programs to assess the potential risks arising from these programs. We believe the following policies and practices reflect sound risk management practices within our compensation programs and mitigate excessive risk-taking that could harm our value or reward poor judgment by our executives and other employees:

• Use of balanced mix of annual and longer-term incentive opportunities;

• Employ multiple levels of tiered performance (threshold, target, and maximum) in both our STI and LTI programs;

• Targeting pay within a reasonable range of market median;

CABOT CORPORATION    49

2023 PROXY STATEMENT   

Executive Compensation (continued)

• Use of maximum payout caps in both the STI and LTI programs;

• Use of different financial performance metrics across the STI and LTI programs covering multiple dimensions of performance (income statement, balance sheet, share price, etc.);

• Ability of the Committee to use discretion to modify STI awards;

• Annual Committee review and approval of the STI and LTI program design, performance metrics and goals and earned payouts;

• Mix of equity awards and multi-year vesting used in the LTI program;

• Availability of a Company recoupment policy; and

• Use of share ownership guidelines.

Based on these mitigating factors, the Committee agreed with the study’s findings that our compensation programs do not encourage inappropriate or unacceptable risk to the Company, and that any risks are within our ability to effectively monitor and manage and are not reasonably likely to have a material adverse effect on the Company.

Share Ownership Guidelines

To further align the interests of our executives and our shareholders, we maintain share ownership guidelines for members of our Management Executive Committee. Under these guidelines, we expect our CEO to own equity in the Company in an amount equal to five times his or her annual base salary, and each other officer who reports directly to the CEO to own equity in an amount equal to three times his or her annual base salary. Each executive has five years from the date he or she becomes subject to the share ownership guidelines to meet his or her target. The Committee reviews compliance with these guidelines annually. At the time of this filing, all of the members of the Management Executive Committee who have been subject to these guidelines for five years or longer had satisfied such share ownership guidelines.

Recoupment of Compensation

The Company maintains a recoupment (clawback) policy that applies to performance-based compensation, such as STI and LTI compensation, paid to participants in our LTI program (which includes our named executive officers). Under the policy, if the Company is required to restate its financial statements due to material non-compliance with financial reporting requirements under applicable securities laws, and the amount of performance-based compensation awarded or paid would have been lower had the achievement of applicable financial performance been calculated based on the restated financial results, the amount of the excess compensation awarded or paid during the three-year period preceding the date on which the Company is required to prepare the restatement is subject to recoupment, in the discretion of the Compensation Committee. In addition, if a participant knowingly engaged in misconduct that is a material factor in the Company’s obligation to restate its financial statements, the Company will have the right to seek recoupment of the proceeds from the sale of shares issued upon the exercise of stock options or upon the vesting of restricted stock units (including TSUs and PSUs) occurring during the twelve-month period following the filing with the SEC of the financial statements required to be restated, in an amount deemed appropriate by the Compensation Committee under the circumstances. The Company will review and update, if necessary, its clawback policy in light of the SEC’s final clawback rule that was published in late 2022.

Other Information

Retirement and Other Benefit Programs

Except for Mr. Zhu, our named executive officers participate in the full range of benefit programs and are covered by the same retirement plans on the same terms as are generally provided to our full-time U.S. salaried employees, are eligible to participate in and/or receive benefits under our Deferred Compensation Plan and our Death Benefit Protection Plan, and participate in our Senior Management Severance Protection Plan. These plans are described in the footnotes and text that accompany the compensation tables that follow this CD&A.

Mr. Zhu is a participant in our Senior Management Severance Protection Plan, but as a China-based employee, does not participate in the other retirement and benefit programs described above. Instead, Mr. Zhu participates in the China

2023 PROXY STATEMENT   

Executive Compensation (continued)

Supplemental Pension Plan, which is provided to full-time Cabot employees in China, and participates in insurance and other benefit programs consistent with those made available to other employees who are on an international assignment. These benefits, and their costs to Cabot, are described in the footnotes and text that accompany the compensation tables that follow this CD&A.

Health and Welfare Plans

The health and welfare plans offered to our named executive officers are the same as those offered to all other employees working in the same country. Mr. Zhu is also covered by the health and welfare plans and life and disability benefits offered to our employees who are on an international assignment.

Perquisites

We provide our named executive officers a modest level of perquisites, consisting principally of financial planning and tax assistance services and an executive physical examination. We provide these benefits to help our executives maintain their health and manage their finances, in each case, so that they can focus their attention on Cabot’s business. Mr. Zhu receives certain benefits because of his international assignment as described further below.

Employment Arrangements

Except for Mr. Zhu, our named executive officers serve without employment agreements.

Under the terms of Mr. Zhu’s relocation and employment arrangements, described in his February 2012 offer letter, he receives additional benefits, many of which are offered to employees who are on an international assignment. These benefits consist of tax equalization, housing (including utilities), a car allowance, annual home leave, and a travel allowance. The tax equalization benefit is intended to ensure that Mr. Zhu’s tax obligations are equal to the taxes he would have paid on his earnings had he remained a resident in Singapore, with the Company paying all other Chinese taxes associated with the income Mr. Zhu earns while based in China. In addition, under the terms of Mr. Zhu’s offer letter with the Company, if Mr. Zhu’s employment is terminated at Cabot’s initiation while based in China, for any reason other than dismissal due to a violation of law or applicable company policy, Cabot will pay the costs to repatriate Mr. Zhu and his family back to Singapore. Mr. Zhu’s base salary and short-term incentive and equity awards are determined in U.S. Dollars and then converted to local China RMB at the time of payment.

Hedging Policy

The Company’s insider trading policy prohibits executives, directors, their family members who share the same address or are financially dependent upon them, and entities owned or controlled by any such persons, from, among other things, engaging in any “short sales”, including short sales “against the box”, or purchases, sales, or other arrangements involving, puts, calls or other derivative securities on the Company’s common stock, and issuing any standing or limit orders for the sale of the Company’s common stock that remain outstanding for more than five days, other than in connection with a Rule 10b5-1 trading plan adopted in compliance with the policy. No categories of hedging transactions are specifically permitted and, other than the transactions described above, no other categories of hedging transactions are specifically disallowed.

Tax and Accounting Information

We consider the tax and accounting rules associated with various forms of compensation when designing our compensation programs. However, to maintain flexibility to compensate our executive officers in a manner designed to promote short- and long-term corporate goals and objectives, the Compensation Committee has not adopted a policy that all compensation must be deductible or have the most favorable accounting treatment to the Company and has paid, and will continue to pay, compensation that is not deductible.

* Title does not reflect changes effective December 1, 2022

1. Mr. Keohane’s fiscal year 2020 annual base salary was $1,000,000. In recognition of the impact of the coronavirus pandemic on the Company’s business and operations during fiscal year 2020, at his request, Mr. Keohane’s salary was temporarily suspended from April 1 through June 30, 2020.

Under the terms of Mr. Zhu’s employment arrangements, his base salary, short-term incentive award, and equity-based compensation are determined in U.S. Dollars and then converted to China RMB at time of payment, or settlement, as applicable. For purposes of the disclosure in this proxy statement, certain amounts that were paid and recorded in China RMB have been converted to U.S. Dollars using the average monthly exchange rate during the 12-month period ended September 30, 2022 of U.S.D. 6.579325 to one China RMB, and, with respect to his fiscal years 2021 and 2020 compensation, using the average monthly exchange rate during the 12-month period ending September 30, 2021 of U.S.D. 6.49925 to one China RMB and the 12-month period ending September 30, 2020 of U.S.D. 7.00695 to one China RMB.

2. We review base salaries annually in November and any changes are generally effective on January 1 of the following calendar year. The amounts reported in this column reflect salary earned during each fiscal year.

3. The amounts reported in this column reflect the aggregate grant date fair value of TSUs and PSUs granted in the applicable fiscal year to each named executive officer, computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. The grant date fair value per unit of the TSUs and PSUs is equal to the closing price of Cabot common stock on the date of grant, with the grant date fair value of the PSUs calculated based on the probable outcome of applicable performance conditions, which assumes that the target level of performance is achieved, and, for PSUs granted in fiscal 2022, these amounts are as follows: Mr. Keohane: $1,662,443; Ms. McLaughlin: $358,710; Mr. Zhu: $323,748; Mr. Kalkstein: $323,748; and Ms. Kalita: $227,486. If the maximum level of performance were to be achieved under the PSUs granted in fiscal 2022, the grant date fair value of these awards would be as follows: Mr. Keohane: $3,324,886; Ms. McLaughlin: $717,420; Mr. Zhu: $647,496; Mr. Kalkstein: $647,496; and Ms. Kalita: $454,972. We pay dividend equivalents on all TSU awards, and on PSUs (to the extent earned) if, and when, we pay dividends on our

common stock, which is factored into the grant date fair value for these awards. The assumptions used to calculate the grant date fair value of stock awards are set forth in Note N to our Consolidated Financial Statements filed with our Annual Report on Form 10-K for fiscal 2022.

4. The amounts reported in this column reflect the aggregate grant date fair value of stock option awards granted in the applicable fiscal year to each named executive officer, computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures, determined using the Black-Scholes option-pricing model. The assumptions used to calculate the grant date fair value of option awards under the Black-Scholes model are set forth in Note N to our Consolidated Financial Statements filed with our Annual Report on Form 10-K for fiscal 2022.

5. The amounts reported in this column consist of:

a. The Cash Balance Plan was terminated on July 31, 2019 and each named executive officer, except Mr. Zhu, who was not a participant in this plan, received a lump sum payment from the plan on September 11, 2020. Therefore, the change in actuarial present value for fiscal 2020, 2021 and 2022 consists only of the benefits under the Supplemental Cash Balance Plan, measured from October 1 to September 30 of the applicable fiscal year. No amounts are attributable to the change in actuarial present value of the benefits under the Supplemental Cash Balance Plan measured in those periods because they were negative as follows: for Mr. Keohane: $(21,469) in fiscal 2020, $(24,417) in fiscal 2021 and $(34,261) in fiscal 2022; for Ms. McLaughlin: $(1,799) in fiscal 2020, $(2,045) in fiscal 2021 and $(2,538) in fiscal 2022; and for Mr. Kalkstein: $(5,113) in fiscal 2020, $(5,821) in fiscal 2021 and $(7,962) in fiscal 2022. Mr. Zhu and Ms. Kalita do not have a balance under the Supplemental Cash Balance Plan. These amounts are presented in accordance with SEC rules, which require the use of the same assumptions as required by FASB ASC Topic 715. When such amounts are negative, they are not reflected in the amount reported in the column. The Supplemental Cash Balance Plan is frozen and, therefore, the change in the present value of accrued benefits (PVAB) is due to (i) one less year to accumulate benefits to normal retirement, resulting in a shorter discounting period and an increase to the PVAB; and (ii) a change in the discount rate assumption for the plan, the net effect of which decreased the PVAB. Details on the Supplemental Cash Balance Plan and the actuarial assumptions to calculate the amounts above can be found below under the heading “Pension Benefits.”

b. Above-market interest (the portion exceeding 120% of the applicable federal long-term rate) credited to deferrals under Cabot’s Deferred Compensation Plan as follows: for Mr. Keohane: $12,074 in fiscal 2021, and $16,097 in fiscal 2022; for Mr. Kalkstein: $4,552 in fiscal 2020, $7,138 in fiscal 2021, and $5,735 in fiscal 2022; and for Ms. Kalita: $1,309 in fiscal 2020, $1,780 in fiscal 2021, and $1,240 in fiscal 2022.

6. The table below identifies the amounts shown for fiscal 2022 in the “All Other Compensation” column. All of the amounts reflect the actual cost to Cabot of providing the payment or benefit described below.

a. The 401(k) Plan, the Supplemental 401(k) Plan, the Deferred Compensation Plan, and the China Supplemental Pension Plan are described under the heading “Deferred Compensation” beginning on page 58.

b. Consists of amounts paid or reimbursed by Cabot for financial planning and tax assistance services during fiscal 2022.

c. Mr. Zhu receives additional benefits that amounted to $918,811 for fiscal 2022. These benefits included the payment by Cabot of expenses related to his assignment to China, consisting of $160,826 for rent and utilities for housing in China, $7,824 for home leaves during the year, and $24,058 for a travel allowance. Mr. Zhu will also receive an estimated $726,103 in tax equalization benefits with respect to fiscal 2022. The tax equalization benefit is intended to ensure that Mr. Zhu’s tax obligations are equal to the taxes he would have paid on his earnings had he remained a resident in Singapore, with the Company paying all other Chinese taxes associated with the income Mr. Zhu earns, including on the vesting of his equity awards and his exercise of stock options, while based in China. Certain of these amounts were paid in China RMB and have been converted to U.S. dollars as described above.

d. Consists of the amount paid by Cabot for an annual physical exam (Mr. Keohane $2,600 in 2022); and for each U.S.-based named executive officer, the cost to Cabot of insurance premiums under our Death Benefit Protection Plan, which provides a death benefit equal to three times a named executive officer’s annual base salary at the time of his or her death, up to a maximum benefit of $3,000,000. These premiums are paid directly to the life insurance carriers. For Mr. Zhu, this amount includes the insurance premium paid by Cabot under the Company’s international benefits program for health and welfare, life, and disability insurance, as well as $30,493 for his car allowance. The life insurance plan for employees on international assignment provides a benefit equal to two times base salary up to a maximum benefit of $400,000.

The table does not include any amounts related to the use of tickets for sporting and cultural events by the named executive officers because no incremental costs are incurred by Cabot in providing these benefits. Cabot purchases season tickets to sporting and cultural events for business outings with customers and vendors. If the tickets are not being used for business purposes, the named executive officers and other employees may have opportunities to use these tickets.

1. The amounts in these columns represent bonus opportunities under our STI program and assume that performance goals for adjusted EBIT, NWC days, and DFCF, the financial metrics for corporate performance for fiscal 2022 as described in the Compensation Discussion and Analysis section of this proxy statement, are achieved at the threshold, target, and maximum levels, as applicable. The amounts included in the “Threshold” column reflect 50% of the target bonus opportunity payable for corporate performance, which is weighted 70% under our STI program, and do not reflect any payout for individual performance because there is no formal threshold payout level for individual performance. The amounts included in the “Target” column reflect 100% of the total target bonus opportunity payable for both corporate and individual performance. The amounts included in the “Maximum” column reflect 200% of the total target bonus opportunity payable for both corporate and individual performance. Actual bonus payments made under our STI program for fiscal 2022 are included in the Summary Compensation Table on page 52 in the column “Non-Equity Incentive Plan Compensation.”

2. The amounts in these columns represent PSU awards. These awards vest three years after the date of grant, generally subject to the named executive officer’s continued employment through the vesting date, and the number of shares issuable, if any, when the award vests will depend on the degree of achievement of corporate performance goals for each year within the three-year performance period. For fiscal 2022 awards, the two financial metrics used to measure corporate performance were adjusted EPS and adjusted RONA. The amount included in the “Target” column reflects the total number of shares that would be issued when the award vests if the Company achieves target financial performance against the adjusted EPS and adjusted RONA goals each year. The amount in the “Threshold” column reflects 50% of the target award and the total number of shares that would be issued when the award vests if the Company achieves threshold financial performance each year, and the amount in the “Maximum” column reflects 200% of the target award and the total number of shares that would be issued when the award vests if the Company achieves maximum financial performance each year.

3. The amounts in this column represent TSU awards. These awards vest three years after the date of grant, generally subject to the named executive officer’s continued employment through the vesting date.

4. All stock options were granted with an exercise price equal to the closing price of our common stock on the date of grant and generally vest, subject to continued employment, over a three-year period (30% on each of the first and second anniversaries of the date of grant and 40% on the third anniversary of the date of grant).

5.  a. Reflects the grant date fair value of TSUs, PSUs and option awards, calculated in accordance with FASB ASC Topic 718 as described in more detail in footnotes 3 and 4 to the Summary Compensation Table above.

b. The grant date fair value per TSU and PSU is equal to the closing price of Cabot common stock on the date of grant ($58.27) and, for PSUs, was calculated based on the probable outcome of applicable performance conditions, which assumes that the target level of performance is achieved. The grant date fair value of these awards assuming the maximum level of performance is achieved is set forth in footnote 3 to the Summary Compensation Table. We pay dividend equivalents on all TSU awards, and on PSUs (to the extent earned), if, and when, we pay dividends on our common stock, which is factored into the grant date fair value for these awards. Option awards are valued using the Black-Scholes option pricing model. The assumptions used to calculate the grant date fair value of these awards are set forth in Note N to our Consolidated Financial Statements filed with our Annual Report on Form 10-K for fiscal 2022.

1. Under our LTI Program, options generally vest over a three-year period as follows, generally subject to the named executive officer’s continued employment through the vesting date: 30% on each of the first and second anniversaries of the date of grant and 40% on the third anniversary of the date of grant. All options have a date of grant that is ten years prior to the “Option Expiration Date” listed in the table.

Executive Compensation (continued)

2. Reflects the portion of fiscal 2020 PSUs earned based on the degree of achievement of the annual financial performance goals (adjusted EPS and adjusted RONA goals) for each of the three years within the three-year performance period of the award. These units vested on November 8, 2022, which was the third anniversary of the date of grant for all awards, and were settled on November 21, 2022, the date the Compensation Committee determined the achievement of the adjusted EPS and adjusted RONA goals used to determine the number of PSUs earned during fiscal year 2022.

3. Reflects the portion of fiscal 2021 PSUs earned based on the degree of achievement of the annual financial performance goals (adjusted EPS and adjusted RONA goals) for the first two years within the three-year performance period of the award. These units will vest on November 13, 2023, generally subject to the named executive officer’s continued employment through the vesting date.

4. Reflects the portion of fiscal 2022 PSUs earned based on the degree of achievement of the annual financial performance goals (adjusted EPS and adjusted RONA goals) for the first year within the three-year performance period of the award. These units will vest on November 12, 2024, generally subject to the named executive officer’s continued employment through the vesting date.

5. The value of unvested TSUs and PSUs was calculated by multiplying the closing price of our common stock on September 30, 2022 ($63.89) by the number of unvested TSUs and PSUs (with the number of PSUs determined as described in notes 6 and 7 below).

6. Reflects the portion of fiscal 2021 PSUs that may be earned based on the degree of achievement of the annual financial performance goals (adjusted EPS and adjusted RONA goals) for the third year within the three-year performance period of the award. These units, to the extent earned, will vest on November 13, 2023, generally subject to the named executive officer’s continued employment through the vesting date. The number of shares shown for each named executive officer’s PSU award assumes the Company will achieve the maximum adjusted EPS goal and maximum adjusted RONA goal with respect to such award, based on fiscal 2022 performance.

7. Reflects the portion of fiscal 2022 PSUs that may be earned based on the degree of achievement of the annual financial performance goals (adjusted EPS and adjusted RONA goals) for the second and third years within the three-year performance period of the award. These units, to the extent earned, will vest on November 12, 2024, generally subject to the named executive officer’s continued employment through the vesting date. The number of shares shown for each named executive officer’s PSU award assumes the Company will achieve the maximum adjusted EPS goal and maximum adjusted RONA goal with respect to such award, based on fiscal 2022 performance.

Option Exercises and Stock Vested Table

The following table shows the options exercised by our named executive officers and the TSUs and PSUs that vested for each named executive officer during fiscal 2022. The value of options realized on exercise is the difference between the closing price of our common stock on the exercise date and the exercise price, multiplied by the number of shares acquired on exercise. The value of stock realized on the vesting of TSUs is the product of the number of shares that vested and the closing price of our common stock on the vesting date. The value of stock realized on the vesting of PSUs is the product of the number of shares that vested and the closing price of our common stock on the settlement date.

Pension Benefits

Cabot’s salaried employees in the U.S. who were employees prior to January 1, 2014 (including each of our U.S.-based named executive officers) participated in Cabot’s Cash Balance Plan and, in certain cases, our Supplemental Cash Balance Plan. The Cash Balance Plan and the Supplemental Cash Balance Plan were each frozen on December 31, 2013, with no further benefits accruing under those plans after that date. The Cash Balance Plan was terminated in fiscal 2019 and fully settled in fiscal 2020.

2023 PROXY STATEMENT   

Executive Compensation (continued)

The Supplemental Cash Balance Plan is an unfunded, non-qualified defined benefit plan created to provide benefits in circumstances where maximum limits established under the Internal Revenue Code prevented participants from receiving some of the benefits that would otherwise have been provided under the tax-qualified Cash Balance Plan. The Internal Revenue Code limited the amount of compensation that could be considered annually to determine benefits under the Cash Balance Plan. The Supplemental Cash Balance Plan was intended to provide eligible employees the same benefits they would have earned under the Cash Balance Plan if this compensation limit did not apply. While the plan is frozen, interest-based credits are earned on account balances during each calendar year at the one-year U.S. Treasury bill rate determined as of November of the previous year until the participant begins receiving benefit payments. At retirement at any age or other termination of employment, a participant eligible for benefits may receive his or her vested account balance in a lump sum payment or in annual installment payments. Participants were 100% vested in their accounts after three years of employment with Cabot.

As of September 30, 2022, all of our U.S.-based named executive officers who are participants in the Supplemental Cash Balance Plan were fully vested in their account balances.

Pension Benefits Table

For each of our U.S.-based named executive officers, the following table shows the actuarial present value of each named executive officer’s accumulated benefits under the Supplemental Cash Balance Plan as of September 30, 2022, the last day of our most recent fiscal year, and the pension plan measurement date used for financial statement reporting purposes for our fiscal 2022 financial statements.

Deferred Compensation

The following narrative describes benefits provided under Cabot’s Deferred Compensation Plan, 401(k) Plan, Supplemental 401(k) Plan and China Supplemental Pension Plan.

Deferred Compensation Plan

Our Deferred Compensation Plan is a non-qualified plan that permits certain employees in the U.S. to voluntarily defer in any year up to 50% of their base salary and up to 100% of any short-term incentive and sales incentive bonus awarded.

58    CABOT CORPORATION

2023 PROXY STATEMENT   

Executive Compensation (continued)

Under this plan, participants receive a credit equal to 10% of the amount they defer, which is intended to account for the fact that any compensation that is deferred is not eligible compensation for purposes of Company contributions under the 401(k) Plan or the Supplemental 401(k) Plan. All of our U.S.-based named executive officers are eligible to participate in the Deferred Compensation Plan. Mr. Keohane and Mr. Kalkstein made contributions to the plan for fiscal 2022.

All deferred amounts are credited with interest at a rate equal to the Moody’s Corporate Bond Rate for the month of November prior to the beginning of the applicable calendar year. Amounts that are deferred in a particular year are credited to a participant’s account as if they were invested in the account on the first day of the applicable calendar year and notional interest is applied as if the participant had earned the deferred amount on the first day of the calendar year. Earnings are compounded daily. The Moody’s rate used to calculate interest payable for calendar year 2022 was 2.96%. Participants in the Deferred Compensation Plan can elect to defer receipt of their eligible compensation until a specified date (an “in-service election”) or until they cease to be employees of Cabot (a “termination/retirement election”). Participants may elect to receive deferred amounts in a lump sum payment, in installments over a period of up to five years in the case of an in-service election or, if the participant’s account balance is at least $50,000, in installments over a period of up to ten years for a termination/retirement election.

401(k) Plan and Supplemental 401(k) Plan

Under the 401(k) Plan, which is a tax-qualified defined contribution plan in which Cabot’s U.S.-based named executive officers and other employees in the U.S. participate, Cabot makes a retirement contribution equal to 4% of a participant’s eligible compensation (consisting of base salary and cash bonuses) and a matching contribution of 100% of a participant’s contribution, up to 6% of the participant’s eligible compensation. These Company contributions are allocated to the participant’s account in accordance with his or her investment elections.

The Supplemental 401(k) Plan is an unfunded, non-qualified defined contribution plan under which we provide credits to our U.S.-based named executive officers and certain other employees in the U.S. that cannot be made under the 401(k) Plan due to limitations imposed by the Internal Revenue Code. Credits to the Supplemental 401(k) Plan are made at the same percentage of pay that Company contributions would have been made under the 401(k) Plan were it not for the limitations imposed by the Internal Revenue Code. To receive Company contributions equal to the 401(k) Plan retirement contribution under the Supplemental 401(k) Plan, the participant must meet the annual IRS compensation limit. To receive Company contributions equal to the 401(k) Plan matching contribution under the Supplemental 401(k) Plan, the participant is required to have made contributions at the maximum applicable annual IRS contribution limit before they reach the annual IRS compensation limit. Amounts credited to the Supplemental 401(k) Plan are treated as if invested in Cabot common stock. Participants may elect to receive distributions in a lump sum payment after separation from service or, if a participant’s account balance is at least $50,000, in installments over a period of three, five or ten years beginning after separation from service. All distributions are made in shares of Cabot common stock, except for certain grandfathered accounts distributions, which are made in cash. None of our named executive officers have grandfathered accounts.

Under both the 401(k) Plan and Supplemental 401(k) Plan, participants are immediately vested in the matching contributions and vested in other Cabot retirement contributions after two years of employment with Cabot. All of our named executive officers are fully vested in their account balances under these plans.

China Supplemental Pension Plan

All full-time Cabot China employees are eligible to participate in the China Supplemental Pension Plan. The China Supplemental Pension Plan is a funded noncontributory plan under which Cabot China makes a taxable contribution equal to 5%-11% of a participant’s monthly base salary (excluding overtime pay, where applicable, and allowances and subsidies) based on years of service and job level. These contributions are allocated to the participant’s account into investment options selected by Cabot China and managed by external managers appointed by Cabot China. Participants are vested in these contributions after five years of employment. Mr. Zhu is our only named executive officer eligible to participate in the China Supplemental Pension Plan. Mr. Zhu currently receives a company contribution in an amount equal to 9% of his base salary. He is fully vested in his account balance, and will receive a lump sum distribution in cash upon his retirement or separation from service without cause.

1. The amounts contributed by Mr. Keohane and Mr. Kalkstein to the Deferred Compensation Plan represent a portion of their STI awards earned with respect to fiscal 2022 as reported in the “Non-Equity Incentive Plan Compensation” column of the Summary Compensation Table on page 52. Ms. McLaughlin and Ms. Kalita did not make deferrals under the Deferred Compensation Plan in calendar 2022.

2. These amounts represent credits made by Cabot that are accrued under the Deferred Compensation Plan and the Supplemental 401(k) Plan and contributions made by Cabot to the China Supplemental Pension Plan, and are reported in the Summary Compensation Table on page 52 under the heading “All Other Compensation.”

3. For the Deferred Compensation Plan, earnings represent the amount credited based on the Moody’s interest rate for the year. For the Supplemental 401(k) Plan, earnings represent the value of dividends earned and investment gains or losses as if the account balance had been invested in Cabot common stock. For the China Supplemental Pension Plan, earnings represent the value of dividends earned and investment gains and losses, converted from China RMB to U.S. Dollars. The portion of the earnings that represents above-market interest (the portion exceeding 120% of the applicable federal long-term rate) under Cabot’s Deferred Compensation Plan is reported in the Summary Compensation Table on page 52 under the heading “Change in Pension Value and Nonqualified Deferred Compensation Earnings”.

4. The aggregate balance amounts under the Deferred Compensation Plan and the China Supplemental Pension Plan include deferrals or contributions, as the case may be, made for prior fiscal years. For individuals who were named executive officers in the fiscal years in which the deferrals were made, the amount of the compensation deferred under the Deferred Compensation Plan was included in such individuals’ compensation as reported in the Summary Compensation Table included in the proxy statement for each such fiscal year.

Potential Payments Upon Termination or Change in Control

Our named executive officers are eligible to receive certain benefits if their employment is terminated, including following a change in control. This section describes various termination of employment scenarios and the payments and benefits payable under those scenarios. A table quantifying the estimated payments and benefits assuming a termination of employment and/or a change in control, as applicable, occurred on September 30, 2022 follows this narrative description. The account balances under the Supplemental Cash Balance Plan, 401(k) Plan and Supplemental 401(k) Plan immediately vest and become payable upon a change in control of Cabot. All of our named executive officers who participate in these plans are vested in their account balances under these plans. There are no other single trigger benefits provided by Cabot to the named executive officers.

2023 PROXY STATEMENT

Potential Payments Following a Change in Control

Severance Plan

Participants in our Senior Management Severance Protection Plan (the “Severance Plan”) are the members of our Management Executive Committee and other employees as determined by our Compensation Committee and, as of September 30, 2022, consisted of eleven employees, including all of our named executive officers.

Under the Severance Plan, participants are entitled to severance payments if their employment with Cabot terminates within two years following a change in control (for any reason other than cause, disability, death, or a termination initiated by the participant without good reason). Under the Severance Plan, Mr. Keohane is entitled to a lump sum payment equal to three times the sum of his base salary and bonus (each, as determined below) and continued health and welfare benefits for a period of three years (i.e., medical and dental benefits, long-term disability coverage, and life insurance) and Mses. McLaughlin and Kalita and Messrs. Zhu and Kalkstein are each entitled to a lump sum payment equal to two times the sum of their base salary and bonus (each, as determined below) and continued health and welfare benefits for a period of two years. In addition, under the Severance Plan, each participant is entitled to receive a pro-rated bonus with respect to the fiscal year in which the termination occurs and outplacement services in an amount up to 15% of his or her base salary.

Base salary under the Severance Plan is calculated at the greater of the rate in effect (i) immediately before the change in control or (ii) as of the participant’s employment termination date. The bonus is calculated at the greater of (i) the participant’s target annual incentive bonus for the fiscal year in which the change in control occurs or the fiscal year in which the participant’s employment is terminated, whichever was greater, or (ii) the highest annual incentive bonus amount paid or payable to the participant for any of the three fiscal years preceding the fiscal year in which the change in control occurs.

The Severance Plan also includes a “better of” provision. Under this provision, a participant will be entitled to receive either the full amount of payments (and pay any applicable excise tax imposed by Section 4999 of the Internal Revenue Code) or such lesser amount that is not subject to the excise tax, whichever results in the greater after-tax benefit to him or her.

The provision of severance benefits under any other plan or program provided by Cabot or its affiliates, or pursuant to any agreement with Cabot or its affiliates, or by law, counts toward our obligation to provide the benefits under the Severance Plan so that the benefits are not duplicative.

Retirement and Equity Incentive Plans

The accrued account balances under the Supplemental Cash Balance Plan, 401(k) Plan, and Supplemental 401(k) Plan immediately vest and become payable upon a change in control of Cabot. All of our named executive officers are vested in their account balances under the plans in which they participate.

Upon a change in control of Cabot, the Compensation Committee, as administrator of our Amended and Restated 2017 Long-Term Incentive Plan, will have discretion to provide for the assumption or continuation of some or all outstanding awards or any portion of an award, the grant of new awards in substitution by the acquirer or survivor, or the cash-out of some or all awards. Further, the Compensation Committee retains authority to accelerate the vesting of awards. The Compensation Committee has provided, and intends to continue to provide, for “double trigger” vesting upon a change in control. This means that if an award remains outstanding following a change in control, such as if the acquiring company assumes the award, vesting would be accelerated only if the participant’s employment was involuntarily terminated without cause or by the participant for good reason within two years following the change in control.

Termination of Employment Upon Disability or Death

For Cabot’s full-time employees based in the U.S., including our U.S.-based named executive officers, a termination of employment upon disability is determined under the terms of Cabot’s long-term disability plan and is deemed to occur one year following the date of disability. A U.S.-based employee who becomes disabled would receive (i) benefits under our long-term disability plan, and (ii) continued participation in our medical, dental, and life insurance plans in accordance with the terms of those plans if the employee has completed ten years of service with Cabot. We have not included

Executive Compensation (continued)

a value for these benefits in the table on pages 63-64 because the plans do not discriminate in scope, terms, or operation in favor of our named executive officers compared to the benefits offered to all salaried U.S. employees. Under the terms of our disability plan for employees on an international assignment, in the event Mr. Zhu becomes disabled, he is entitled to a monthly benefit of up to $10,000 while he remains disabled, until he reaches age 65. In addition, the accrued account balances under the Supplemental Cash Balance Plan, 401(k) Plan, Supplemental 401(k) Plan and China Supplemental Pension Plan immediately vest and become payable upon termination of employment by reason of death or disability. All of our named executive officers are vested in their account balances under the plans in which they participate.

Under the terms of Cabot’s Amended and Restated 2017 Long-Term Incentive Plan, if any participant (including a named executive officer) ceases to be an employee because of disability or death, his or her unvested stock options and unvested TSUs would immediately vest. In the case of PSUs, the total number of units that vests is the sum of the units that have been earned based upon performance as of the date of the termination of employment.

We provide each of our U.S.-based named executive officers with a death benefit under our Death Benefit Protection Plan equal to three times their base salary up to a maximum benefit of $3,000,000, which is payable to their beneficiary at the time of their death. Mr. Zhu is provided with life insurance coverage under the life insurance plan for international assignees that provides a benefit equal to two times base salary up to a maximum benefit of $400,000, which is payable to his designated beneficiary in a lump sum in the event of his death.

Termination of Employment Upon Retirement

Upon retirement, participants in the Supplemental Cash Balance Plan are entitled to receive benefit payments, and participants in the 401(k) Plan, the Supplemental 401(k) Plan and China Supplemental Pension Plan may receive a distribution of their account balances. Participants in the U.S. retirement plans are eligible for early retirement upon attaining age 55 and completing at least 10 years of service. As of September 20, 2022, Mr. Keohane is the only one of our named executive officers that meets the eligibility criteria for early retirement under these plans.

Termination for Cause or Voluntarily Without Good Reason

As described above, no severance payments under the terms of the Severance Plan are payable if a participant’s employment is terminated for cause or if he or she terminates employment without good reason. In addition, no benefits are payable under the terms of our Supplemental 401(k) Plan or Supplemental Cash Balance Plan or the China Supplemental Pension Plan if a participant’s employment is terminated for cause.

2023 PROXY STATEMENT   

Executive Compensation (continued)

1. For Mr. Keohane, severance pay is equal to three times the sum of (x) base salary and (y) the greater of (i) his highest bonus in the three fiscal years preceding fiscal 2022 or (ii) his target bonus under our STI program for the fiscal year. For each of our other named executive officers, severance pay is equal to two times the sum of (x) base salary and (y) the greater of (i) his or her highest bonus in the three fiscal years preceding fiscal 2022 or (ii) his or her target bonus under our STI program for the fiscal year. The amounts in this column include the target bonus amount for fiscal 2022 and has not been prorated because the table assumes the termination occurred on the last day of the fiscal year.

2. The amounts for accelerated unvested equity include the following: (i) in the case of death or disability, the value of unvested TSUs, unvested PSUs that have been earned based upon performance as of September 30, 2022 and unvested options; and (ii) in the case of a qualifying termination following a change in control, the value of unvested TSUs, unvested PSUs (consisting of units earned based on performance as of September 30, 2022 and unearned units assuming target performance is achieved) and unvested options. The value of unvested TSUs and PSUs that become vested as described herein for all named executive officers was calculated by multiplying the closing market price of our common stock on September 30, 2022 ($63.89) by the number of shares underlying unvested TSUs and PSUs. The value of unvested options that become vested as described herein for all named executive officers was calculated by multiplying the number of shares underlying the unvested options by the difference between the closing market price of our common stock on September 30, 2022 and the option exercise price.

3. Continued perquisites and benefits include only those benefits provided to a named executive officer that are not generally provided to all employees located in the same country.

The amount reported in the event of death, with the exception of Mr. Zhu, represents an amount equal to three times base salary up to a maximum benefit of $3,000,000, which is payable in a lump sum to the named executive officer’s designated beneficiary under our Death Benefit Protection Plan, which is an insured benefit applicable to all U.S.-based named executive officers. The amount reported for Mr. Zhu represents an amount equal to two times base salary up to a maximum benefit of $400,000, which is payable in a lump sum to his designated beneficiary under the terms of our life insurance plan for employees on an international assignment. In the event Mr. Zhu’s death is the result of an accident, his designated beneficiary may be entitled to receive an additional benefit in the amount of $500,000 (which is not reflected in the table above). The amount reported for Mr. Zhu in the event of disability reflects 12 monthly payments of $10,000, which he is eligible to receive annually while he is disabled until age 65 under the terms of our disability plan for employees on an international assignment, subject to the terms of the plan. For each of our named executive officers, the amount reported in the event of a termination following a change in control represents the cost to Cabot of continued health and welfare benefits (for a period of three years for Mr. Keohane and for a period of two years for each of our other named executive officers) and outplacement services in an amount equal to 15% of the officer’s base salary. For Ms. Kalita, the amount in the table does not include the cost to Cabot of all of the health and welfare benefits for which she could be entitled in this event because currently she has not elected to participate in all such plans for which she is eligible. In addition to the amounts included in the table, if Mr. Zhu’s employment is terminated at Cabot’s initiation, while based in China, for any reason other than dismissal due to a violation of law or applicable company policy, Cabot will pay the costs to repatriate Mr. Zhu and his family back to Singapore. No amount is included in this table with respect to a potential future repatriation.

4. Payments do not take into account the “better of” provision in the Severance Plan described above on page 61, which, under certain circumstances, could reduce the amount of the payment.

2023 PROXY STATEMENT   

Executive Compensation (continued)

CEO Pay Ratio

As required by the Item 402(u) of Regulation S-K, we are required to report on the relationship between the annual total compensation of our CEO, Mr. Keohane, and the median of the annual total compensation of our employees. In accordance with SEC requirements, the median-paid employee may be identified once every three years if there has been no change to our employee population or compensation arrangements that we reasonably believe would result in a significant change to our pay ratio disclosure. Because there were changes to the median-paid employee’s compensation arrangements in fiscal 2022 that we believe would significantly affect our pay ratio disclosure, we have identified a new employee representing the median-paid employee for purposes of this pay ratio analysis.

To identify the median of the annual compensation of all our employees as well as to determine the annual total compensation of our median employee we took the following steps:

• We determined that, as of September 30, 2022, the last day of our most recent fiscal year, our employee population consisted of 4,280 full-time and part-time employees in the U.S. and foreign jurisdictions. We did not exclude any non-U.S. employees from our worldwide employee population under any of the permitted exclusions.

• To identify the median employee, we used annual base salary or base wages as our consistently applied compensation measure. We first determined each employee’s annual base salary or base wages reported in our global system of record for the twelve-month period ending on September 30, 2022. For any employees who were employed on September 30, 2022 but not for this full twelve-month period, we annualized their base salary or base wages. We converted all salaries and wages paid in foreign currency to U.S. dollars using the September 2022 month-end currency conversion rate.

After identifying our median employee, we calculated the annual total compensation of the median employee and our CEO in the following manner:

• The median employee’s annual total compensation represents the amount of such employee’s compensation for fiscal 2022 that would have been reported in the Summary Compensation Table in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K if the employee were a named executive officer for fiscal 2022.

• The annual total compensation of our CEO represents the amount reported in the “Total” column of our 2022 Summary Compensation Table included on page 52 of this proxy statement.

For fiscal 2022, our CEO’s annual total compensation was $7,948,029 and the median of the annual total compensation of all employees of Cabot (excluding our CEO) was $62,661. Based on this information, our pay ratio is approximately 127 to 1. This ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

In calculating the pay ratio, the SEC allows companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions reflecting their unique employee populations. Therefore, our reported pay ratio may not be comparable to that reported by other companies due to differences in industries and geographical dispersion, as well as the different estimates, assumptions, and methodologies applied by other companies in calculating their pay ratios.

2023 PROXY STATEMENT   

Proposal 2 — Advisory Approval of Executive Compensation

In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, we are providing stockholders the opportunity to vote on a non-binding, advisory resolution to approve the compensation of our named executive officers as disclosed on pages 32-64 of this proxy statement (commonly referred to as “say-on-pay”).

We had a very strong fiscal 2022 in terms of both financial performance and the progress we made in executing our Creating for Tomorrow strategy and advancing our sustainability objectives. We believe that the compensation received by our named executive officers for fiscal 2022 appropriately aligned executive pay with our outstanding corporate performance. The portion of the STI awards earned on the basis of our corporate performance paid out at 147.2% of target awards. The PSU awards issued under our LTI program are designed to produce the greatest rewards when strong results are sustained over time. Specifically, the number of shares issuable upon their vesting depends on the degree of achievement of financial performance metrics for each year within a three-year performance cycle. On the basis of our level of achievement in fiscal 2022 against the adjusted EPS and adjusted RONA goals applicable to the PSU awards that were granted in fiscal 2020 and vested in 2022, our named executive officers earned 123% of their target awards. Our fiscal 2022 performance is summarized in the Executive Summary of our Compensation Discussion and Analysis section of this proxy statement.

The types of performance goals that we use for establishing the metrics for our executive compensation programs are the same as the ones we use when setting the strategic objectives of the Company. The use of these metrics is intended to motivate behavior and executive decisions that will lead to the successful execution of our strategy. Our executive compensation programs also align the interests of our stockholders and executives by tying compensation to the Company’s short- and long-term financial and strategic growth objectives. We believe this will create value for our stockholders over time.

For these reasons, the Board is asking stockholders to approve, on an advisory basis, the compensation of our named executive officers.

The text of the resolution is as follows:

“VOTED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and the narrative discussion, is hereby APPROVED.”

Vote Required

Because the vote we are asking you to cast is non-binding, there is no minimum vote required for approval. Our Board and the Compensation Committee value the views of our stockholders and will consider the outcome of the vote when making future compensation decisions for our named executive officers. We believe that Cabot benefits from constructive dialog with our stockholders. We will continue to reach out to our stockholders on these and other important issues and we encourage our stockholders to contact us. Stockholders who wish to communicate with our Board should refer to “Communications with the Board” in this proxy statement for additional information on how to do so.

Recommendation

The Board of Directors believes that the compensation of our named executive officers is appropriate and recommends a vote “FOR” the approval of the compensation of our named executive officers.

2023 PROXY STATEMENT   

Proposal 3 — Advisory Vote on Frequency of Say-on-Pay Vote

In Proposal 2, we are asking stockholders to cast an advisory vote for the compensation of our named executive officers as disclosed in this proxy statement (commonly referred to as a “say-on-pay” vote). In accordance with the requirements of Section 14A of the Exchange Act and the related rules of the SEC, in this proposal, we are providing stockholders the opportunity to cast an advisory vote on whether a “say-on-pay” vote should occur once every one, two or three years. This vote, like the say-on-pay vote, is not binding on our Board.

Our Board of Directors recommends that future say-on-pay votes be conducted every year to provide stockholders with an opportunity to regularly evaluate the Company’s overall executive compensation program. As described in detail in the Compensation Discussion and Analysis section above, our executive compensation program is designed to provide a competitive level of total compensation necessary to attract and retain executives qualified to execute our business strategy, to motivate them to contribute to our short- and long-term success and to align their interests with those of our stockholders. An annual vote will provide us with regular stockholder input on our executive compensation program, and allow us to engage with stockholders to better understand and respond to prior voting results and implement any appropriate changes to our program.

The text of the resolution is as follows:

“VOTED, that the option of once every one, two or three years that receives the highest number of votes properly cast for this resolution will be determined to be the preferred frequency recommended by the stockholders of the Company with which the Company is to hold a non-binding, advisory stockholder vote to approve the compensation of the Company’s named executive officers in accordance with Section 14A of the Securities Exchange Act of 1934.”

Vote Required

Although this advisory vote is non-binding on our Board, our Board and the Compensation Committee will review the voting results and take them into consideration when determining the frequency of future say-on-pay votes. Because this proposal seeks the input of our stockholders and provides our stockholders with the option to vote to hold a say-on-pay vote once every one, two or three years, there is no minimum vote requirement for this proposal. Although our Board recommends holding a say-on-pay vote every year, you have the option to specify one of four choices for this proposal on the proxy card: one year, two years, three years or abstain.

Recommendation

The Board of Directors recommends that you vote to conduct a non-binding, advisory vote on executive compensation “EVERY YEAR.”

Audit Committee Matters

Audit Committee Report

The Audit Committee of the Board of Directors is comprised of three non-employee directors. The Board has determined that all of the members of the Audit Committee satisfy the requirements of the New York Stock Exchange (“NYSE”) as to independence and financial literacy. In addition, the Board has determined that Mr. Morrow and Mr. Wilson are audit committee financial experts as defined by SEC rules. Our responsibilities are set forth in our written charter and are described above under the heading “Board Composition — How Our Board Operates — Audit Committee” on page 13.

We have sole authority to appoint, retain, terminate and determine the compensation of our independent registered public accounting firm. At least annually, we review the performance and qualifications of our independent registered public accounting firm to determine whether to retain such firm on behalf of the Company. Deloitte & Touche LLP (“D&T”) has been Cabot’s independent registered public accounting firm since 2007. During its tenure as Cabot’s independent registered public accounting firm, D&T has gained significant depth of understanding of Cabot’s global businesses, operations and systems, accounting policies and practices, and internal control over financial reporting. In accordance with SEC rules and D&T’s policies, audit partners are subject to rotation requirements to limit the number of consecutive years an individual partner may provide services to us. For lead and concurring audit partners, the maximum number of consecutive years of service in that capacity is five years. In fiscal 2021, the Audit Committee, after consultation with management, approved the appointment of a new lead audit partner pursuant to this policy.

One of our primary responsibilities is to assist the Board in its oversight of the quality and integrity of Cabot’s financial statements. We met ten times during fiscal 2022. A number of those meetings included executive sessions with D&T and with Cabot’s Chief Financial Officer, Corporate Controller, Vice President of Internal Audit, and General Counsel. We took numerous actions to discharge our oversight responsibility with respect to the audit process, which are summarized in this report.

As described in more detail under the heading “Board Composition — Our Board’s Role in Risk Oversight and in Overseeing our Progression on Environmental, Social and Governance (“ESG”) Matters and Activities” on page 9, we focus on Cabot’s financial risk exposures and the actions management has taken to monitor and mitigate such risks, and oversee Cabot’s enterprise risk management processes.

Review of Audited Financial Statements with Management

We reviewed and discussed with management Cabot’s audited consolidated financial statements for the fiscal year ended September 30, 2022.

Review of Financial Statements and Other Matters with Independent Registered Public Accounting Firm

We discussed with D&T Cabot’s audited consolidated financial statements for the fiscal year ended September 30, 2022, including the matters required to be communicated by the standards of the Public Company Accounting Oversight Board (“PCAOB”) and the SEC. This included a discussion of accounting policies and practices critical to our financial statements. We also received the written disclosures and the letter from D&T required by PCAOB Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, which requires auditors to annually disclose in writing all relationships that in the auditor’s professional opinion may reasonably be thought to bear on independence and to confirm their independence, and discussed with D&T its independence from Cabot. In addition, we discussed Cabot’s internal controls over financial reporting and management’s assessment of the effectiveness of those controls with management, Cabot’s internal auditors and D&T. We reviewed with both D&T and Cabot’s internal auditors their audit plans, audit scope and identification of audit risks. We also discussed the results of the internal audit examinations with and without management present. In addition, any reports or concerns the Company receives relating to financial matters are communicated directly to the Chair of the Audit Committee.

Recommendation that Financial Statements be Included in Annual Report

Based on the reviews and discussions referred to above, we recommended to the Board of Directors that the audited financial statements be included in Cabot’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022 for filing with the SEC, and appointed D&T as the Company’s independent registered public accounting firm for fiscal 2023.

Audit Fees

Fees for professional services rendered by D&T for fiscal 2022 and 2021 were as follows:

	Fiscal 2022		Fiscal 2021
Audit Fees	$	5,121,000	$	4,817,000
Audit-Related Fees	$	170,600	$	447,000
Tax Fees	$	0	$	0
All Other Fees	$	2,000	$	32,000

The audit services for each of fiscal 2022 and 2021 include professional services for the audit of Cabot’s consolidated financial statements included in the Annual Report on Form 10-K (including audit of internal control over financial reporting) and review of financial statements included in Cabot’s Quarterly Reports on Form 10-Q, consultations regarding on-going financial accounting matters, and services that are normally provided by the auditor in connection with statutory and regulatory filings or engagements. Statutory audit fees in foreign jurisdictions are billed in local currency.

The audit-related services for fiscal 2022 consisted of fees for (i) certain agreed upon procedures performed and related to regulatory compliance matters; (ii) comfort letter procedures; and (iii) other attestation services. During fiscal 2021, audit-related services consisted primarily of fees associated with audit activities related to the sale of the Purification Solutions business, as well as fees for (i) certain agreed upon procedures performed and related to regulatory compliance matters; (ii) diligence and other strategic activities; and (iii) other attestation services. All Other Fees for fiscal 2021 and fiscal 2022 include fees for certain training materials and technical library subscription fees.

Audit Committee Pre-Approval Policy

The Audit Committee has adopted a policy requiring the pre-approval of audit and non-audit services to be provided by Cabot’s independent registered public accounting firm. The policy identifies the guiding principles that must be considered by the Audit Committee in approving services to ensure that the auditor’s independence is not impaired; describes the audit, audit-related, tax and other services that may be provided and the non-audit services that are prohibited; and sets forth pre-approval requirements for all permitted services. In some cases, pre-approval is provided by the full Audit Committee for the applicable fiscal year for a particular category or group of services, subject to an authorized amount. In other cases, the Audit Committee specifically pre-approves services. To ensure compliance with the policy, the Audit Committee requires the independent registered public accounting firm to report on actual fees charged for each category of services at least quarterly. The Audit Committee has delegated authority to the Chair of the Committee to pre-approve additional services that need to be approved between scheduled Audit Committee meetings, provided that the estimated fee for any such services does not exceed $100,000, and any such pre-approvals must then be communicated to the full Audit Committee.

All of the services described above for fiscal 2022 and 2021 were pre-approved by the Audit Committee or Committee Chair.

2023 PROXY STATEMENT   

Proposal 4 — Ratification of Appointment of Independent Registered Public Accounting Firm

Introduction

The Audit Committee has appointed Deloitte & Touche LLP (“D&T”) to serve as Cabot’s independent registered public accounting firm for its fiscal year ending September 30, 2023. The Sarbanes-Oxley Act of 2002 requires the Audit Committee to be directly responsible for the appointment, compensation and oversight of the audit work of the independent registered public accounting firm. However, the Board of Directors is submitting the appointment of D&T to the stockholders for ratification as a matter of good corporate practice. Should the stockholders fail to ratify the appointment of D&T, the Audit Committee may reconsider the appointment and may retain D&T or another accounting firm without resubmitting the matter to stockholders. Even if the stockholders ratify the appointment of D&T, the Audit Committee may select another firm if it determines such selection to be in the best interest of Cabot and its stockholders.

Representatives from D&T are expected to be present at the 2023 Annual Meeting. The representatives will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions from Cabot’s stockholders.

Vote Required

Approval of this proposal requires the affirmative vote of a majority of the votes properly cast on the proposal. Abstentions and broker non-votes will have no effect on the results of this vote.

Recommendation

The Board of Directors recommends that you vote “FOR” the ratification of the Audit Committee’s appointment of Deloitte & Touche LLP as Cabot’s independent registered public accounting firm for fiscal 2023.

2023 PROXY STATEMENT   

Appendix A

NON-GAAP MEASURES

Adjusted EPS, Adjusted EBIT, Total Segment EBIT, Discretionary Free Cash Flow and Adjusted RONA are not measures of financial performance under U.S. generally accepted accounting principles (GAAP) and should not be considered substitutes for measures of performance reported under GAAP. Management believes these non-GAAP measures provide investors with greater transparency to the information used by Cabot management in its financial and operational decision-making, allow investors to see Cabot’s results through the eyes of management, and better enable Cabot’s investors to understand Cabot’s operating performance and financial condition. Management also uses Adjusted EPS, Adjusted EBIT, Discretionary Free Cash Flow and Adjusted RONA as key measures in evaluating management performance for incentive compensation purposes.

Adjusted EPS. Adjusted EPS excludes “certain items”, which are items of expense or income that management does not consider representative of our fundamental ongoing performance. These certain items are described in detail in Note T of our consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022. Management believes excluding these items facilitates operating performance comparisons from period to period by eliminating differences caused by the existence and timing of certain expense and income items that would not otherwise be apparent on a GAAP basis and evaluates the Company’s operating performance without the impact of these costs or benefits.

The following table reconciles adjusted EPS to earnings per share from continuing operations.

Fiscal Year	2020			2021			2022
Net income (loss) per share attributable to Cabot Corporation	$	(4.21	)	$	4.34		$	3.62
Less: Certain items after tax per share	$	(6.29	)	$	(0.68	)	$	(2.66	)
Adjusted earnings per share	$	2.08		$	5.02		$	6.28

Total Segment EBIT and Adjusted EBIT. Total Segment EBIT is our income (loss) before income taxes and equity in earnings of affiliated companies, less “certain items” and other unallocated items. Please refer to Item 7 of the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022 for a discussion of Total Segment EBIT that explains in more detail how we calculate this measure, why management believes this measure is useful and the purposes for which management uses this measure. We calculate Adjusted EBIT by deducting unallocated corporate costs before corporate depreciation from our calculation of Total Segment EBIT.

The following table reconciles Total Segment EBIT and Adjusted EBIT to Income (loss) before income taxes and equity in earnings of affiliated companies.

($M)/Fiscal Year	2022
Income (loss) before income taxes and equity in earnings of affiliated companies	$	335
Less: Certain items	$	(183)
Less: Other unallocated items	$	(124)
Total Segment EBIT	$	642
Less: Unallocated corporate costs before corporate depreciation	$	59
Adjusted EBIT	$	583

Discretionary Free Cash Flow. We calculate discretionary free cash flow by deducting changes in our net working capital and sustaining and compliance capital expenditures from our Cash flow from operating activities.

CABOT CORPORATION    A-1

2023 PROXY STATEMENT   

Non-Gaap Measures (continued)

The following table reconciles discretionary free cash flow with Cash flow from operating activities.

($M)/Fiscal Year	2022
Cash flow from operating activities	$	100
Less: Changes in net working capital	$	(431)
Less: Sustaining and compliance capital expenditures	$	136
Discretionary Free Cash Flow	$	395

Adjusted RONA. We calculate Adjusted RONA by dividing the most recent twelve months’ adjusted net income (loss) (a non-GAAP numerator) by adjusted net assets (a non-GAAP denominator). In the numerator, we exclude certain items, net of tax, from income (loss) from continuing operations as calculated under GAAP. The denominator consists of our operating assets, which are: net property, plant and equipment; adjusted net working capital; and investments in equity affiliates. We calculate the items in adjusted net assets using the most recent five quarters’ average to normalize the impact of large intra-period movements.
