&nbsp;&nbsp;<br>CEO Letter<br>

Dear Shareholders:

West continues to fulfill its mission of improving patient lives through the containment and delivery of injectable therapies—a mission that has guided our work for the past century and one that continues to be critical to the customers who rely upon our partnership and expertise to bring their innovative, new therapies to the patients that need them.

Our performance in 2022 was solid with an overall organic net sales growth of approximately 8% following the dynamic and accelerated growth of 2020 and 2021 generated by the COVID-19 pandemic. Now that the pandemic is under better control, we are seeing a return to our core baseline growth. We have continued with approximately $285 million in capital investments across our manufacturing network to meet the increased customer demand. I thank our team of more than 10,000 people across the globe that has delivered this sustained success during such a challenging period.

A highlight of 2022 was the initiation of our landmark collaboration with Corning to build the next generation of leading elastomer-glass containment system solutions. Together with the launch of the Daikyo CZ 2.25 mL insert needle syringe and the FDA approval of three drugs using our SmartDose<sup>®</sup> technology, these milestones demonstrate that West is continuing to invest and innovate to support our customers and the future needs of patients, setting the Company up for long-term growth.

I am proud to report that West has once again been recognized for our Environmental, Social and Governance ("ESG") business practices with a MSCI AA rating; a listing in *Newsweek's* Americas Most Responsible Companies for 2022; and a top 50 listing in *Barron's* Most Sustainable Companies. We have made tremendous strides across the six priority areas of our ESG strategy and newly defined performance indicators, which we will outline in detail in our annual ESG Report this spring.

As our Company grows, so does our team. We welcomed 600 new team members over the course of the year and added new senior leaders including a Chief Quality Officer and a New Global Head of Corporate Development. In addition, we elected an 11th member to the Board of Directors—Stephen H. Lockhart, M.D., Ph.D., a board-certified anesthesiologist and former Chief Medical Officer of Sutter Health, whose contributions have already proven indispensable.

As in years past, the Management team has worked together with the Board of Directors to ensure the performance of our team is reflected in their compensation and awards framework and is aligned with the business results we have delivered. The detailed pay-for-performance plans of our executives, which in the past have received more than 93 percent support from you, our shareholders, are detailed in this Proxy Statement.

As we celebrate 100 years in business, we know that the West name has come to mean so much to so many people. We realize that our products and pursuit of scientific innovations are critical to healthcare across the globe, which is why we are so committed to support patient health today and well into the future. I am grateful to all our shareholders who have been a part of West's journey so far and I thank you for your continued support of our Company.

2022 Business Highlights\*

Our market-led focus, global operations and One West philosophy continued to be the foundations of our Company's 2022 success in both net sales growth and operating cash flow. We continue to see favorable trends in the pharmaceutical and biotech industries that are expected to enable the Company to fulfill our long-term growth strategy, including:

● Biotechnology continues to emerge as a promising source of therapies and products for patient care, requiring specialized packaging and delivery solutions due to the sensitive nature of these large molecules. We continue to have a high participation rate in providing primary containment components for approved new molecular entities, especially large-molecule injectable drugs.

\* *Certain forward-looking statements are included in this Proxy Statement. They use such words as "will," "continue," "estimate," "expect," "looking to the future," and other similar terminology. These statements reflect Management's current expectations regarding future events and operating performance and speak only as of the date of this document. These statements are based on Management's beliefs and assumptions, current expectations, estimates, and forecasts. There are many factors that can influence the Company's future results that are beyond the ability of the Company to control or predict.

PROXY SUMMARY

● The regulatory landscape continues to evolve as global regulatory bodies are updating guidance on the manner in which newer, self-administered combination products are reviewed and approved for sale with increased attention on quality and documentation that are required.

● Continued research of subcutaneous administration, as an alternative to intravenous administration, prompted by its cost-effectiveness and increased patient adherence, fuels more opportunities to develop self-administration technology that places easy-to-use delivery systems in the hands of patients.

Each year, we have seen growing interest and demand for our high value product offerings, delivery device platforms and our services. Customers are also coming to West for our scientific expertise and insight into the regulatory landscape that governs our industry. This demand has translated into positive results for the business. In 2022, we reported:

● Full-year 2022 net sales of $2.887 billion, a 2.0% increase; organic net sales growth of 7.7%; currency translation decreased net sales growth by 570-basis points

● Full-year 2022 reported-diluted EPS of $7.73, a decrease of 10.8%, and full-year 2022 adjusted-diluted EPS of $8.58 remained unchanged from the prior year

● Full-year 2022 operating profit margin of 25.4%, a decrease of 4.5%, and full-year 2022 adjusted operating profit margin of 26.4%, a decrease of 1.9%

● Full-year 2022 operating cash flow was $724.0 million, an increase of 24.0%; capital expenditures were $284.6 million, compared to $253.4 million over the same period last year, and represented 9.9% of full-year 2022 net sales; free cash flow (operating cash flow minus capital expenditures) was $439.4 million, an increase of 32.9%

Long-Term Shareholder Return

Examining our results over the past five years, West has consistently delivered against its objectives, posting long-term sales growth and EPS improvements. The Company has also outperformed both the S&P 500 Index and S&P 500 Health Care Index in Total Shareholder Return ("TSR") during this same period.

ELECTION OF DIRECTORS

Election of Directors

Director Nominations, Skills and Criteria

Candidates for nomination to our Board are recommended by the Nominating and Corporate Governance Committee ("NCGC") in accordance with the NCGC's charter, our Amended and Restated Articles of Incorporation, our Bylaws, and our Corporate Governance Principles. All persons recommended for nomination to our Board, regardless of the source of the recommendation, are evaluated by this Committee with the Board determining the final slate of nominees.

The Board and the NCGC consider, at a minimum, the following factors in recommending potential new Board members or the continued service of existing members:

● A director is nominated based on his or her professional experience. A director's traits, expertise and experience add to the skill-set of the Board as a whole and provide value in areas needed for the Board to operate effectively.

● A director must have high standards of integrity and commitment, and exhibit independence of judgment, a willingness to ask hard questions of Management and the ability to work well with others.

● A director should be willing and able to devote enough time to the affairs of the Company and be free of any disabling conflict.

● All the non-employee directors should be "independent" as outlined in our independence determination standards ("Independence Standards").

● A director should actively participate in the decision-making process, demonstrate a willingness to express ideas and engage in constructive discussion with other Board members, Management and relevant persons, be willing to make difficult decisions and demonstrate diligence and faithfulness in attending Board and Committee meetings.

● The Board generally seeks active or former senior executives of public companies, particularly those with backgrounds in international operations, healthcare or public health fields, science or technology backgrounds and individuals with financial expertise.

When reviewing nominees, the NCGC considers whether the candidate possesses the qualifications, experience and skills it considers appropriate in the context of the Board's overall composition and needs. We also strive for a Board composition that reflects a diverse mix of backgrounds, experiences, expertise, skill sets, perspectives and opinions. Therefore, our director nomination process seeks candidates who bring a diversity of professional experiences and personal backgrounds, which includes consideration of a candidate's age, gender, race and ethnicity, where appropriate.

The NCGC also reviews annually with the Board the size and composition of the Board and its committees to determine the qualifications and areas of expertise needed to further enhance the composition of the Board. In determining whether to add new directors, we review our skills matrix annually to determine the targeted skills that we believe will most significantly enhance the diversity of experience and expertise on our Board. We balance the current skill sets versus the desired optimal mix of skill sets given their relative importance to the Company.

During 2022, the NCGC undertook a thorough review of the vital skills for a director to possess to align with best practices across our industry and competitors. We refined the definitions of each skill, added executive leadership to our slate of skills and adjusted our approach beyond mergers and acquisitions to focus on corporate development more broadly. Finally, we surveyed the directors to ensure that the skills matrix contained in the Proxy Summary accurately reflects each director's skills. Below are the defined skills that the Board considers as most vital to help a director provide value and leadership to help drive West's success.

Board members must be well-versed in our Mission, Vision and Values, as well as our corporate strategy. West's mission is to contain and deliver injectable therapies that improve patient lives, and it aspires to be the world leader in integrated containment and delivery of injectable medicines, both of which rely on the Company's core values of:

● Passion for Customers— *We innovate to continuously improve our product and service offerings to meet future customer and patients' needs*.

● Leadership in Quality— *We never compromise on quality. Every dose, every time. 100% commitment*.

● One West Team— *Our diverse team spans the globe, but we are united by our integrity and mutual respect for one another, the safety of our work environment and the communities in which we operate.* 

Board members are expected to oversee and support Management in driving the success of the business by focusing on the following five strategic imperatives, while simultaneously requiring that the organization uphold its commitment to ESG principles, cultural values and ethics:

● Continuing to execute our market-led strategy with enhanced commercial effectiveness

● Innovating new product offerings and expanding into emerging markets

● Optimizing global operations and supply chain networks, including automation enablement

● Accelerating digitization to drive performance

● Building and supporting our global team, including enhanced efforts regarding diversity, equity and inclusion

Under the heading "Director Nominee Biographies," we provide an overview of each nominee's principal occupation, business experience and other directorships of publicly traded companies, together with the qualifications, experience,

key attributes and skills the NCGC and the Board believe will best serve the interests of the Company and our shareholders.

Shareholders who wish to recommend or nominate director candidates must provide information about themselves and their candidates and comply with procedures and timelines contained in our Bylaws. These procedures are described under "Shareholder Proposals or Nominations" in this Proxy Statement.

------

Board Commitment to Diversity, Equity and Inclusion

Board diversity is critical to the success of the Company. Our Corporate Governance Principles reflect the Board's commitment to ensuring its membership has sufficient diversity of experience, skills and personal characteristics to support the long-term success of the Company. As presently constituted, the Board represents a deliberate mix of members who have a deep understanding of our business, as well as members who have different skill sets and points of view. Therefore, the NCGC's evaluation of director nominees includes consideration of candidates who bring a diversity of professional experiences and personal backgrounds, including review of characteristics such as age, gender, race and ethnicity.

In 2022, the Board undertook a director search to replace retiring board member Patrick Zenner. At the conclusion of the search, the Board appointed Stephen H. Lockhart, M.D., Ph.D., a leading African American physician-executive, to the Board. As detailed in his biography below, Dr. Lockhart brings a broad range of skills and experience in healthcare, executive leadership and science and technology to the Board. In future director searches, the Board will continue to actively seek candidates with racial and/or ethnically diverse backgrounds.

West has a long-standing commitment to Diversity, Equity and Inclusion ("DEI"), which is inherent in our core value of One West Team. We are in the business of helping our customers bring new medicines and treatments that advance life for patients who represent all dimensions of diversity. Our purpose is an important reminder that we must continue to listen and learn from one another with safe and inclusive environments to create the path to a better future.

The Board has overseen and encouraged Management's efforts to bolster the DEI efforts across the Company. For example, West's Chief Executive Officer and executive leadership team review DEI objectives throughout the year to ensure continuous focus and improvement. Today, 33% of West's elected Officers are women, and 67% are women and/or people of color. West has made great strides over the past several years in sourcing team members from diverse backgrounds for leadership roles across the organization. As of December 31, 2022, 44% of our senior leaders were women and/or minorities.

The Board recognizes its role in overseeing the Company's culture and in holding Management accountable for the creation and stewardship of a culture that values DEI. One of the Company's top priorities is building a diverse and inclusive workforce where team members are respected and feel confident in bringing their unique ideas to the table. As discussed below, this is also one of our six ESG priorities as well. The Company understands that to attract and retain talented team members, we must continue to focus on providing exceptional employee experiences for all team members, given their diversity, including during the onboarding of new team members, in the content of recruiting materials, management training, succession planning, affirmative action plans, global mentoring and our employee engagement survey. To foster transparency and continued growth in this area, the Company publishes its annual Consolidated EEO-1 Reports on its website, *www.westpharma.com/about-west/corporate-responsibility*.

------

Board Refreshment and Retirement Age

We are committed to board refreshment and have added four new directors over the past six years. These additions are the result of a thoughtful process designed to ensure an effective balance of historical perspective and an understanding of the evolution of our business with fresh viewpoints and insights.

The Board believes that a diverse mix of long tenured and new Board members provides a good and appropriate balance of experience to enhance shareholder value. The Board believes that directors provide meaningful, independent oversight

and advice at any age. Our Corporate Governance Principles include a retirement age of 75. This means that a non-employee director generally must retire on the date of the Annual Meeting of Shareholders immediately following his or her 75th birthday; provided, however, that the Board may review individual contributions, continuity and tenure in making a determination as to whether a member who has already attained age 75 must retire.

An employee director must submit his or her resignation from the Board upon the date he or she ceases to be an executive officer of the Company.

------

Board Evaluation Process

Each year, the Board and each of its committees review their performance during executive sessions. This review centers around questions directors are asked regarding their individual performance and the performance of the Board/Committee. These questions include topics such as contributions made to Board deliberations, the relationship between members, quality of the materials provided, the relationship with Management, contributions to key functions/responsibilities of the Board and topics that they would like to see added or deleted to meeting agendas.

Additionally, the NCGC assesses the evaluation process annually and adjusts the process when desirable improvements are identified. The NCGC reviews several matters, including the issues to focus on in the evaluation and the form and manner of assessment. The NCGC periodically reassesses its position on self-evaluation.

Members of the NCGC reach out to each director individually to discuss performance and any concerns and relays them to the Board using an interview template approved by the NCGC. This process assists the full Board with obtaining different perspectives, encourages the collection of candid information and ensures a high level of engagement.

The Board believes this evaluation system, coupled with our strong Chair of the Board and open-door policy, which promotes sharing of ideas among all directors, makes for a robust process that ensures the Board's effectiveness.

DIRECTOR NOMINEE BIOGRAPHIES

Proposal 1 — Election of Directors

Our shareholders are asked to consider eleven nominees for election to our Board to serve for a one-year term until the 2024 Annual Meeting of Shareholders, or until their successors, if any, are elected or appointed, or their earlier death, resignation, retirement, disqualification or removal. The names of the nominees for director, their current positions and offices, tenure as a Company director, their qualifications and other characteristics are set forth in the biographies below. The table below also lists each nominee's current Board committees.

All the nominees are current Company directors and all non-employee directors have been determined by our Board to be independent. Our NCGC reviewed the qualifications of each of the nominees, finding that each nominee possesses the required attributes and that all nominees collectively strike the appropriate balance of diversity of knowledge, age, skills, expertise, gender and race, and recommended to our Board that each nominee be submitted to a vote of our shareholders at the Annual Meeting. The Board approved the Committee's recommendation at its meeting on February 21, 2023.

Each of the nominees has agreed to be named and to serve, and we expect each nominee to be able to serve if elected. If any nominee is unable to serve, the NCGC will recommend to our Board a replacement nominee. The Board may then designate the replacement nominee to stand for election. If you voted for the unavailable nominee, your vote will be cast for his or her replacement.

BOARD AND DIRECTOR INFORMATION AND POLICIES

Board and Director Information and Policies

Our Board structure reflects our Corporate Governance Principles and commitment to good governance. The Board believes the governance structure we have created among the Board, its Committees, the Board Chair, the Lead Independent Director, the CEO and Management is supporting the sustainable growth of the Company.

During 2022, our full Board met six times. Nine of the eleven directors attended all the Board meetings and their assigned Committee meetings in 2022, with the other two directors attending over 94% of the meetings. Our Board is committed to ensuring that directors attend meetings and that the Board and its Committees devote sufficient time necessary for the effective oversight of the Company and its Management. Additionally, during the annual performance review process, the Board assesses the time commitments for our Board against the time commitments of each member's outside positions to ensure each director has ample time to devote to their duties as a West director.

Our Board also holds regular executive sessions of only independent directors to review, among other things, the Company's strategy and Management's operating plans, the criteria by which our CEO and other senior executives are measured, Management's performance against those criteria and other related issues, and to conduct a self-assessment of its performance. Last year, our independent directors held five executive sessions.

All then-serving directors attended the 2022 Annual Meeting and all continuing directors are expected to attend the 2023 Annual Meeting.

------

Board Leadership Structure

The current governance structure of the Board follows:

● Effective May 24, 2022, the offices of Chair and CEO were combined

● The Board elected a strong Lead Independent Director, also effective May 24, 2022

● The Board has established and follows robust Corporate Governance Principles

● All Board members, other than Mr. Green, are independent

● All Board Committees are composed solely of independent directors

● Our independent directors meet regularly in executive session both at the Board and Board committee levels

● Our directors as a group possess a broad range of skills and experience sufficient to provide the leadership and strategic direction the Company requires as it seeks to enhance long-term value for shareholders

The Board recognizes that one of its key responsibilities is to evaluate and determine its optimal leadership structure to ensure both independent oversight of senior management and a highly engaged and high-functioning Board. The Board does not have a policy as to whether the Chair should be an independent director, an affiliated director or a member of management. Under our By-laws and Corporate Governance Principles, the Board can and will change its leadership structure if it determines that doing so is in the best interest of West and its shareholders at any given time. The independent Directors do not view any particular board leadership structure as preferred and consider the Board's leadership structure on at least an annual basis. This consideration includes the evaluation of alternative leadership structures in light of the Company's current operating and governance environment, a review of peer company leadership structures and investor feedback, with the goal of achieving the optimal model for Board leadership and effective oversight of senior leaders by the Board.

BOARD AND DIRECTOR INFORMATION AND POLICIES

The independent directors annually appoint a Chair of the Board. To ensure robust independent leadership on the Board, if the individual appointed as Chair is not an independent director, or when the independent directors determine that it is in the best interests of the Company, the independent directors will also annually appoint a Lead Independent Director. The Board recognizes that in circumstances where the positions of Chair and CEO are combined or the Chair is not independent, it is imperative that the Board elect a strong Lead Independent Director with a clearly defined role and set of responsibilities. Our Corporate Governance Principles align with the Board's goal of achieving the optimal model for Board leadership and investor preferences. See "Lead Independent Director" below.

Additionally, maintaining an independent board with a Lead Independent Director permits open discussion and assessment of the Company's ability to manage these risks and provides the appropriate balance between strategy development and independent oversight of management.

------

Chair of the Board of Directors

The responsibilities of the Chair include:

● Presiding at all meetings of the shareholders

● Chairing Board meetings

● Consulting with the Lead Independent Director regarding agendas and schedules for each Board meeting; each independent director may add items to the agenda

● Making reports to the Board and shareholders and ensuring that all orders and resolutions of the Board or its Committees are carried into effect

Our current Chair, Mr. Green, has been serving as Chair since May 24, 2022. Each year, the Board considers the role of the Chair and who is sitting in that role. After leading the Company to strong financial and operational growth over the last eight years, and because of his day-to-day involvement with and intimate understanding of our business, industry and management team, the Board believes that Mr. Green continues to be best situated to serve as Chair.

------

Lead Independent Director

Our Corporate Governance Principles provide that if our Chair is not independent, our independent directors shall annually elect an independent director to serve as Lead Independent Director to preside over executive sessions of the Company's independent directors, facilitate the flow of information and communication between the independent directors and the Chair of the Board and perform such other duties as may be specified from time to time by the Board. The responsibilities of the Lead Independent Director will include:

● Presiding at all sessions of the independent directors or whenever the Chair is not present

● Calling meetings of and setting agendas for the independent directors whenever he or she deems appropriate

● Approving agendas and schedules for each Board meeting in consultation with the Chair, assuring that (1) board agendas contain those items that the independent directors believe are important to their understanding and evaluation of the Company and its affairs; and (2) information provided to and presentations made to the Board, and other communications, are in keeping with the Board's needs and wishes

● Approving and reviewing minutes of meetings of the Board

● Leading the Board's process for selecting the CEO

● Overseeing the independent directors' annual performance evaluation of the Chair and CEO

24 \| 2023 Annual Meeting and Proxy Statement

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

BOARD AND DIRECTOR INFORMATION AND POLICIES

● Together with the Chair and Chair of the NCGC, conducting the annual board assessment process

● Acting as lead for Board discussion of any subject where the CEO would not, in the judgment of the Lead Independent Director, be the appropriate person to chair such discussion

● Serving as principal liaison between the CEO and the independent directors

● Performing such other duties as the Board may from time-to-time delegate to assist the Board in fulfilling its responsibilities

The Lead Independent Director provides important counsel to the Chair by offering input regarding key strategic ideas and suggestions proposed by the Chair and Management. This helps to bring about a strong two-way discussion among the independent directors and Management.

Paolo Pucci has served as Lead Independent Director since May 24, 2022. Mr. Pucci is an independent director who possesses a wealth of knowledge regarding biopharmaceutical markets from his experience as an executive leader of several large biopharmaceutical companies. Mr. Pucci encourages frank and open dialogue with other Board members and Management, including Mr. Green. Mr. Pucci's recent service as a public company CEO and his service as a Board member of several emerging biotech companies brings experience that we believe is important. His international background also adds to the diverse knowledge base of our Board. Mr. Pucci's expertise in new drug development, his executive experience working for large multinationals and his non-U.S. training are valuable additions to our Board.

------

Committees

The Board has five standing committees:

● Audit Committee

● Compensation Committee

● Finance Committee

● Innovation and Technology Committee

● Nominating and Corporate Governance Committee

From time to time, the Board may form ad hoc committees to address specific situations as they arise. Each committee consists solely of independent directors. All directors may attend any committee meeting, even if he or she is not a member of that committee. Our Board Chair attends all Board meetings and attends virtually all Committee meetings unless there is a scheduling conflict. Each standing committee has a written charter, which is posted in the *"Investors—Corporate Governance"* section of our website at *www.westpharma.com*. You may also request a copy of each committee's charter from our Corporate Secretary. Below we set forth the current members of each Committee (as of the date of this Proxy Statement) and its core functions.

BOARD AND DIRECTOR INFORMATION AND POLICIES

------

The Board's Role in Risk Oversight

The Board and its Committees play an active role in overseeing Management's day-to-day responsibility for assessing and managing our risk exposure.

The Board regularly reviews and monitors the risks associated with our enterprise strategy, financial condition and operations and specifically reviews the enterprise risks associated with our five-year plan. In particular, the Board reviews our risk portfolio, confirms that Management has established risk management processes that are functioning effectively and efficiently and are consistent with our corporate strategy, reviews the most significant risks and determines whether Management is responding appropriately to these risks.

The Board performs its risk oversight role by using several different levels of review. Each Board meeting begins with an overview by the CEO that describes the most significant issues, including risks affecting the Company, as well as business updates from each reportable segment. In addition, the Board reviews in detail the business and operations of each reportable business segment quarterly, including the primary risks associated with that segment.

Our Enterprise Risk Management ("ERM") program helps us manage the risks inherent in our business, by gaining a greater understanding and awareness of risks facing the business, ensuring risk-appropriate mitigation efforts are in place and regularly monitoring and ensuring the Company meets or exceeds the expectation of all stakeholders, including investors and regulators. The ERM program includes both a top-down and bottom-up risk identification and management ("RIM") process, security risk management, crisis management, business continuity and disaster recovery elements. Our integrated framework includes the methods and processes the Company uses to identify and address the risks most likely to positively or negatively impact our ability to meet business objectives and achieve strategic initiatives.

During 2022, we transitioned to the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") ERM framework, which is a top benchmark for public companies. This framework includes the elements of (1) developing a strong governance and risk-aware culture; (2) embedding ERM concepts into strategic planning; (3) identifying ERM risks, scoring and prioritizing; (4) reviewing and revising critical response plans; and (5) continuously identifying and sharing information across the network.

This ERM process considers materiality of risks by assessing the importance to our external stakeholders and the importance to our success. The materiality matrix can be found in West's Corporate Responsibility Report on our website at: *www.westpharma.com/about-west/corporate-responsibility*. Information on that website is updated periodically and believed to be true at the time it is posted, but it is not filed and does not constitute part of this Proxy Statement.

We have enhanced our multidisciplinary ERM and Security team to better position the Company to evaluate, control and respond to the risks and challenges presented by unforeseen natural and human-caused disasters and health crises. This includes hiring our first full-time dedicated enterprise risk manager who engaged in a robust review to identify our most significant risks. Our ERM function works with functional leaders and partners with our Internal Audit and Compliance departments to increase visibility, accountability and communication. Additionally, our dedicated Business Continuity and Resilience team engaged our manufacturing sites to review and substantially update our business continuity plans to ensure consistency of delivering quality products during times of crisis, particularly considering our role in the global healthcare supply chain.

We apply an enterprise-wide approach to Business Continuity Management ("BCM") to maintain a duty of care to employees, protect customers and corporate assets and minimize financial, legal, reputational and strategic impact. Additionally, West aims to ensure the continuation and rapid recovery of critical business, manufacturing and distribution activities during major internal or external incidents. The BCM program aligns with the International Standards Organization (ISO) 22301 and other applicable standards and regulatory requirements. Executive leadership provides program sponsorship and governance at global, regional and local levels. As a result, BCM entails all business and administrative areas within West in terms of planning, training and exercising.

The Board monitored, reviewed and approved the enhancements to our ERM program. Several Board and Committee meetings provided updates regarding our progress in updating our program. They assisted with risk assessment, defining risk tolerance and validating the ERM process. Overall, the Board focuses on the enterprise risks affecting the Company.

28 \| 2023 Annual Meeting and Proxy Statement

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

BOARD AND DIRECTOR INFORMATION AND POLICIES

Each Board Committee has been delegated the responsibility for the oversight of specific risks that fall within its areas of responsibility, as cataloged through the RIM process, including:

● The Audit Committee oversees the processes used in our ERM program and also oversees the management of financial reporting, compliance, litigation and cybersecurity risks, as well as the steps Management has taken to monitor and control such exposures

● The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation policies, plans and arrangements and the extent to which those policies or practices increase or decrease risk for the Company

● The Finance Committee assesses the risks associated with allocation of our capital, potential acquisitions, divestitures and major business partnerships

● The Innovation and Technology Committee reviews risks associated with emerging, and potentially disruptive, science and technology trends, quality and regulatory landscapes changes, intellectual property and our innovation, research and development and technology strategy

● The Nominating and Corporate Governance Committee manages risks associated with the independence of the Board, potential conflicts of interest, communications with shareholders, ESG and the effectiveness of the Board

Although each Committee is responsible for evaluating certain risks and overseeing the management of those risks, the full Board is regularly informed about those risks through regular Committee reports.

#### Cybersecurity
Cybersecurity is of special concern, and the Audit Committee oversees the vital work necessary to understand our cybersecurity risk and the related risk mitigation activities, including an assessment of the strength and depth of our defenses and processes to maintain security. At each of its quarterly meetings, the Audit Committee reviews cybersecurity strategy, risks and Key Performance Indicators ("KPIs") and separately meets with our Senior Director, Infrastructure and Cybersecurity; Senior Director, Internal Audit; and Chief Compliance Officer who provide additional insight into our cybersecurity and privacy strategy and tactics. The full Board also receives regular updates from the Audit Committee and key team members responsible for cybersecurity. Management regularly reviews with the Audit Committee and the Board the possible impact of cybersecurity issues that may arise with tools we use to manage the ordinary course of business, such as our public facing website and e-commerce interface and during times of crisis, when such risks are even greater.

Our approach to mitigating cybersecurity risks includes, but is not limited to: periodic reviews and penetration tests conducted by third party experts; independent ethical hacking and penetration tests of our internal and external services to assess and strengthen our security controls; mandatory security audits for any interfaces that will be interacting with our environment; following secure coding, review and threat modeling best practices; vulnerability scanning of internet accessible assets in collaboration with the Cybersecurity and Infrastructure Security Agency—a part of the U.S. Department of Homeland Security; and internal and external trainings for team members. We have adopted the National Institute of Standards and Technology Framework (the "NIST Framework"), which provides a comprehensive method for developing a flexible, repeatable, performance-based and cost-effective approach to identifying and managing cybersecurity risks. We use the NIST Framework to assess and improve our security posture, including engaging Deloitte in 2021 to analyze our information security capabilities against the NIST Framework.

Our cybersecurity defenses also utilize technologies such as next generation firewalls, intrusion detection and prevention measures, security information and event management, anti-malware, advance threat protection, multifactor authentication, network segmentation and encryption to ensure the privacy and security of our customers' data. We also have a dedicated Security Operations Center, monitoring our applications and infrastructure on a 24-by-7 basis which is integrated with our enterprise crisis management framework. In 2022, West did not suffer any known cybersecurity breaches.

Each year, we hold a robust, global Cybersecurity Awareness Campaign across the Company to reinforce key messages around cybersecurity. Employees are required to complete various trainings on cybersecurity upon hire and on an annual

basis, including internally developed cybersecurity training, anti-phishing training and general information security trainings, all of which are provided in multiple languages. We provide continuous updates to our employees, educating them on latest cybersecurity threats and how to protect the Company's systems and assets. We also conduct periodic simulated phishing attacks to identify areas of improvement in employee behavior, including retraining employees as part of the simulated phishing exercises.

------

Executive Officer Succession Planning

One of the primary responsibilities of the Board is to ensure that West has the appropriate Management to execute our long-term strategy. Our Corporate Governance Principles state the Board must plan for succession with respect to the CEO and monitor Management's succession planning for other key executives. In fulfilling this duty, the Board, together with the CEO and Chief Human Resources Officer ("CHRO"), reviews at least annually, the development and retention plans of senior Management talent as well as succession plans for the CEO and other senior Management positions.

During these reviews, the Board discusses:

● Management performance

● Strengths and developmental opportunities needed to prepare senior leaders for greater responsibilities

● Potential internal development job changes

● Succession plans including leadership pipeline, development plans and timelines

● Diversity of leadership and pipeline candidates

● Detailed assessment of the members of the executive leadership team who potentially could succeed the CEO; this review includes a discussion about development plans to help prepare each individual for future succession

In addition, our CEO has as an annual goal regarding the development of senior leaders and the maintenance of the global succession plan for key positions within the Company. To that end, detailed succession and contingency plans in the event the CEO becomes unable to serve for any reason are in place. These plans are reviewed annually by the NCGC and discussed with the Board. Finally, throughout the year, Board members are exposed to leadership pipeline candidates through Management presentations, roundtable discussions and informal meetings to assess the depth of our leadership pipeline.

------

CEO Evaluation Process

In assessing the performance of our CEO, the independent directors engage in a robust assessment process that is managed throughout the year and culminates in a formal annual performance review. The assessment includes the following:

● Independent directors approve the CEO's annual business objectives consisting of both qualitative and quantitative progress against the pillars of our enterprise strategy including: Customer Experience, Operational Effectiveness, Products and Services Expansion, Enterprise Capabilities, People and Culture and Financial Goals

● A comprehensive analysis is undertaken by our Compensation Committee's independent consultant on the robustness of West's financial targets compared against the performance of the peer companies in our Business Segment Group (more details can be found in the "Compensation Discussion and Analysis" section under the "External Benchmarking" heading later in this Proxy Statement)

● Each quarter, the independent directors review the progress made against each objective via a CEO scorecard where the CEO undertakes a self-assessment of performance against the approved annual objectives

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

BOARD AND DIRECTOR INFORMATION AND POLICIES

● Annual anonymous evaluation of the CEO's individual performance by the independent directors on numerous factors, including leadership, strategic planning, financial performance, team member development and engagement, external and internal relations and interactions with the Board

● An analysis of West's total performance over a multi-year period, a competitive benchmark analysis and other relevant information is submitted to the independent directors

Working with the Compensation Committee's independent compensation consultant, the Chair of the Compensation Committee considers all this information in developing its recommendations for compensation, as discussed below in our "Compensation Discussion and Analysis."

------

Environmental, Social and Governance Responsibilities

As a leader in our industry, we recognize our responsibility to conduct business in a sustainable manner and strive to be a good corporate citizen. Our Board helps to shape and monitor Management's approach to material sustainability factors that impact our business. Over the past decade, our ESG efforts have included several key areas of focus: Employee Health and Safety, Quality, Compliance and Ethics, Diversity, Equity and Inclusion, Philanthropy and Environmental Sustainability. More recently, we established a cross-functional ESG Steering Committee made up of leaders in various business functions, which is responsible for helping to set our ESG strategy and ensure it is tied to our overall business strategy. We have adopted a stakeholder approach that considers our shareholders, team members, customers, patients, vendors, the Board, regulatory bodies, finance, operations and our obligations to serve the greater good. The ESG Steering Committee and the ESG team fosters two-way communication between West and these stakeholders. West's Management also routinely reviews materials published by our shareholders and key customers and directly engages with these same stakeholders on key ESG topics. Management updates the NCGC on ESG strategy and communications and reports progress regularly and directly to the Board. Other Board committees are consulted on important related ESG issues.

Using tools such as gap analysis, cost-benefit analysis, risk and opportunity analysis and consulting with subject matter experts, the ESG Steering Committee has identified six priority areas in our 100<sup>th</sup> year with goals that we will strive to achieve by 2030. These priority areas are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Climate, Greenhouse Gases ("GHG") and Renewable Energy

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Environmentally-focused Research and Development

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Operational Waste Reduction

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Sustainable, Diverse and Responsible Supply Chain

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Talent Attraction with a focus on People Managers, Diversity, Equity and Inclusion ("DEI")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. Team Member Retention and Engagement with a focus on People Managers and DEI

As we further refine and establish KPIs, which we expect to align with best practices, our enhanced strategy will be described in our future ESG Reports beginning later this year.

We have received multiple awards for our Corporate Responsibility efforts during 2022, including recognition in *Barron's* as a Top 50 Performer of the Most Sustainable Companies in America, significantly improving our ranking in *Newsweek*'s Most Responsible Companies to number 118, being AA rated (top 5%) by Morgan Stanley Capital International ("MSCI") and Environmental and Social Quality Scores from ISS Corporate Solutions in the top decile.

Detailed below is a brief overview of our progress, which is generally made available in May on our website at *www.westpharma.com/about-west/corporate-responsibility*. As noted above, information is included for reference in this Proxy Statement, but is not deemed filed. Our goals, which were reestablished in 2019 after meeting and exceeding prior goals, align with our Company's strategy as well as with the United Nations Sustainable Development Goals. As a

measure of continuous improvement, West has increased disclosure regarding ESG issues over the past several years and aspires to continue to expand our public reporting and transparency in this area.

*Health and Safety.* Providing a healthy and safe environment for our team members is a fundamental responsibility for Management. We have continued to improve our safety performance through the creation, implementation and execution of leading indicator programs that drive positive lagging indicator performance. In 2022, our goal was to increase program effectiveness through enhanced team member involvement, embedding the safety responsibility deeper into operations and improving tools for proactively identifying, reporting and mitigating risk before an incident can occur. This demonstrated commitment to safety coupled with proactive team member engagement allowed West to achieve our lowest Recordable Incident Rate (RIR) in Company history (0.67).

*Quality.* At West, we are committed to safeguarding the health and safety of patients who use our products and services. We provide high-quality products that are designed to be safe and effective for their intended use. Quality product and system controls are designed to ensure compliance with our high standards and applicable FDA current Good Manufacturing Practices, the International Organization for Standardization standards and other applicable global Ministry of Health regulatory requirements. West utilizes customer feedback and manufacturing data to improve processes and product performance. We have established aggressive and measurable goals to achieve by 2024, which target reductions in manufacturing defects, out-of-specification customer complaints and costs of poor quality while also increasing customer complaint response timeliness.

*Business Compliance & Integrity.* Our compliance program is designed to hold ourselves to the highest standards of quality, integrity and respect as outlined in our Code of Conduct, described later in this Proxy Statement. The program is supported by our education and training program led by our Chief Compliance & Privacy Officer and our annual Compliance Week awareness efforts. West also has significantly enhanced its data privacy efforts and emphasized the importance of speaking up, which is an inherent part of our open-door culture.

*Diversity, Equity and Inclusion.* As discussed above, we strive to create and maintain a workplace rich with diverse talents, ideas and backgrounds, and to create an inclusive environment for all team members to succeed. We have increased awareness, adopted affirmative action programs to identify any gaps and strengthened programs and policies, including a global anti-discrimination and anti-harassment policy. We also maintain team member resource groups to support our culture of respect and inclusion, including creating a new resource group in 2022 called the West disAbility Network. We have restructured our talent development programs with an increased emphasis on DEI issues. Our DEI goals for the next five years include initiatives to increase our ability to attract, develop and retain underrepresented talent at all levels of the organization, while fostering exceptional employee experiences for all team members given their diversity and deepening our cultural competence to enhance inclusivity in the workplace.

*Philanthropy.* West has long placed importance in supporting charities, particularly as they relate to children, people with disabilities, healthcare and Science Technology Engineering and Math ("STEM") education in the communities where our team members live and work. In support of our corporate and ESG missions, we are also increasing our charitable giving in the areas of sustainability, social justice and access to healthcare. In addition, in 2022, West directed funding to nonprofits specifically working to address the COVID-19 pandemic and the Ukraine war. In 2022, charitable giving by the Company, our team members and the Herman O. West Foundation totaled approximately $3.9 million. Despite the continued pandemic, we safely recorded almost 2,400 hours of volunteerism by our team members across our global sites. In the seventh year of our annual food drive, we collected over 64,000 pounds of food, and we infused close to $600,000 into cancer research/support, manufacturing readiness/STEM education, DEI and scholarships. The foundation and our team members have generously donated their resources and time to help those in need in the communities where we live and work. It's an enduring commitment that we are proud to carry forward with an even greater, more positive impact on the world.

*Environmental Sustainability.* We strive to be stewards of a sustainable future by factoring environmental considerations into our decision making for raw materials, production processes and distribution methods. During 2022, we embedded ESG considerations into many of the decision-making processes and worked toward more sustainable solutions. As noted above, we will have additional aggressive KPIs established this year for 2030. Over the past 5 years, we have significantly increased the recycling of our waste while reducing our energy and water consumption year over year. Our current goals are to improve our energy efficiency (by 15%), reduce absolute emissions (by 10%) and reduce water consumption (by 10%) by 2023, while striving to reduce landfill waste by 90% over that same period. We expect to achieve or exceed

these goals. We also have developed a renewable energy roadmap that we will execute over the next decade and beyond to achieve greater GHG emission reductions and targets that align with science-based targets ("SBTi").

Human Capital Management

West is committed to fostering an inclusive and collaborative culture where each person is valued, bringing forth innovation, learning and growth for all our team members. The CEO and the executive team members review diversity and inclusion objectives throughout the year to ensure progress against our aspirational goals. As of the date of this Proxy, six of West's 9 elected officers are women and/or People of Color. Our focus on talent acquisition, performance management, resource planning and leadership development are strongly aligned with our DEI strategies. Semi-annually, our Board reviews West's human capital metrics, such as hiring, attrition and diversity data, which are also used to focus on our annual talent review.

Embedded in our culture is the commitment to safety. The safety of our teams starts at the top and is driven throughout our business by every level of management and by every team member across the globe. It is a commitment made to each other. In our 2022 employee engagement survey, 98% of our team members indicated that they understand their role in creating a safe environment. West's global Health, Safety and Environment ("HSE") team is a critical component in leading and monitoring the safety efforts at our sites. West's Health, Safety and Environment Executive Council oversees all global efforts, identifies and shares best practices across our operations team to monitor and guide our HSE process.

West is committed to providing fair and competitive compensation and benefits programs to attract, retain and reward high performing team members at all levels. We offer a comprehensive total rewards program to support the health, financial and homelife needs of our team members. Total Rewards at West are defined as the value of the compensation and benefits programs offered to team members, which aim to reflect the value of the job and the contribution of the individual, while linking team members' performance to business and personal results. Based on country of employment, West may provide health care and retirement savings programs, as well as paid time off, flexible work schedules and a global Employee Assistance Program.

2022 Shareholder Engagement

Our Board considers regular and constructive engagement with our shareholders to be critical for effective corporate governance. To ensure that the Board considers shareholder views on compensation, corporate governance, ESG, financial and operational strategy and other significant matters, we maintain an active shareholder engagement program. Throughout the year, Management meets with our actively managed, institutional shareholders, which own a majority of our shares. Engagement is a cohesive process involving many functional leaders at West that continues all year long. We present at formal events and also respond to more informal one-on-one meetings on topics collaboratively selected with our shareholders. At every Board meeting, Management discusses feedback provided by our shareholders and solicits Board input, which further informs and bolsters our corporate governance and related efforts.

One area of focus for us and our shareholders is the alignment of pay and performance in a manner that enhances shareholder value. Our shareholders have historically expressed support for our performance goals and metrics. Additionally, Management continues to hear our shareholders express support for our corporate governance framework and Board policies, including our tenure policies. In 2022, we actively engaged with shareholders concerning the change to our Board leadership structure, Board diversity, employee diversity and ESG/sustainability issue.

to specific directors are forwarded to those directors. All other communications are given directly to the Chair of the Board who decides whether they should be forwarded to a Board committee or to Management for further handling.

------

Director Education and Onboarding

The Board believes shareholders are best served by Board members who are well-versed in corporate governance principles and other subject matters relevant to board service. The Board arranges for a series of annual educational presentations on its calendar. During 2022, we held several education sessions including presentations on shareholder engagement and the life sciences industry, as well as education regarding West's products, including a tour of one of West's labs. Also, to encourage continuing director education, all directors may attend any director education programs they consider appropriate to stay informed about developments in corporate governance and the markets we serve. The Company reimburses directors for the reasonable costs of attending director education programs.

The Board also works with Management to ensure that new directors are onboarded through a robust process. The onboarding process includes educational meetings with all officers and other critical members of senior Management who provide insight into the Company's business, strategy and culture; the Board and its Committees; Company policies; and fiduciary and legal obligations. All directors have access to online resources maintained by the Company which includes key charters, policies, procedures, principles, corporate governance documents and similar information. Additionally, all directors are provided access to analyst reports, press releases and investor presentations.

Corporate Governance Documents and Policies

Our principal governance documents are our Corporate Governance Principles, Board Committee charters, director qualification standards, including our Independence Standards and Code of Conduct. Aspects of our governance documents are summarized below.

Corporate Governance Principles

Our Board has adopted Corporate Governance Principles to provide guidance to our Board and its committees on their respective roles, director qualifications and duties, Board and committee composition, organization and leadership. Our NCGC reviews our Corporate Governance Principles annually to ensure they meet best practices in corporate governance. In 2022, the NCGC amended the Corporate Governance Principles to emphasize the strong link between the Lead Independent Director and the Chair in leading the Board. Our Corporate Governance Principles address, among other things:

● Statements of the Board's commitment to high ethical standards and principles of fair dealing

● The requirement to hold separate executive sessions of the independent directors

● The importance of robust executive succession planning and the role of directors in succession planning

CORPORATE GOVERNANCE DOCUMENTS AND POLICIES

West's Code of Conduct

All of our team members, officers and directors are required to comply with our Code of Conduct ("COC") as a condition of employment or service. The COC provides guidance on fundamental ethical and compliance-related principles and practices such as: accurate accounting records and financial reporting; avoiding conflicts of interest; diversity, equal opportunities and respect in the workplace; environment, health and safety; protection and proper use of property and information; and compliance with legal and regulatory requirements. The Board reviews the COC regularly to ensure effectiveness and approved revisions in 2022 to enhance the content structure focused on key principles of ethical business conduct. The Board has adopted a comprehensive Business Compliance and Integrity Program, which was modernized and enhanced with a restatement in July 2020 to align with the U.S. Department of Justice's guidance on the evaluation of corporate compliance programs.

Additionally, the Board has adopted a Supply Chain Policy Statement, as required under the laws of the United Kingdom, which are similar to those in California. This Supply Chain Statement indicates West's compliance with various acts and reaffirms our commitment to the Pharmaceutical Supply Chain Initiative ("PSCI"). PSCI supports the efforts of pharmaceutical suppliers to meet industry expectations with respect to ethics, labor, health and safety, environmental and management systems, including a prohibition against the use of forced, bonded or indentured labor. These commitments are also reflected in our Business Partner Code of Conduct. Both codes are available here: *www.westpharma.com/about-west/corporate-responsibility/compliance-and-ethics.* Jessica Colón is our Chief Compliance & Privacy Officer and reports directly to the Audit Committee of the Board on all compliance matters. Ms. Colon trains the Board on compliance matters and delivers reports on program developments and initiatives to the Audit Committee regularly and no less than annually to the full Board.

------

Director Independence

Our Board has adopted a formal set of categorical Independence Standards. The Independence Standards meet or exceed the independence requirements of the NYSE corporate governance listing standards. Under the Independence Standards, a director must have no material relationship with us other than as a director. The Independence Standards specify the criteria for determining director independence, including strict guidelines for directors and their immediate families regarding employment or affiliation with us, members of our senior Management or their affiliates. The full text of the Independence Standards may be found under the "*Investors—Corporate Governance*" section on our website at *www.westpharma.com*.

The NCGC undertook its annual review of director independence in February 2023. As a result of this review, the NCGC recommended, and the full Board concurred, that no revision of the Independence Standards was required. Subsequently, the Board considered whether any relationships described under the Independence Standards between the Company and each individual director existed. The Board affirmatively determined that each of its non-employee directors is independent of the Company and Management as defined under the Independence Standards.

------

Related Person Transactions and Procedures

The Board has adopted written policies and procedures relating to the NCGC's review and approval of transactions with related persons that are required to be disclosed in proxy statements under SEC regulations. A "related person" includes our directors, officers, 5% shareholders and their immediate family members.

Under these policies, the NCGC reviews the material facts of all related-person transactions, determines whether the related person has a material interest in the transaction and may approve, ratify, rescind or take other actions.

In approving a transaction, the Committee will consider, among other factors, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person's interest in the transaction.

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

CORPORATE GOVERNANCE DOCUMENTS AND POLICIES

The Committee reviews and pre-approves certain types of related person transactions, including certain transactions with companies at which the related person is an employee only, and charitable contributions that would not disqualify a director's independent status. The policy and procedures can be found in the "*Investors—Corporate Governance*" section of our website, *www.westpharma.com*.

We have no related person transactions required to be reported under applicable SEC rules.

------

Political Contributions and Lobbying

While we encourage directors, officers and team members to become involved in the political process in their individual capacity, including personal contributions to political campaigns, no West team member or director may conduct personal political activity on Company time or use Company funds, property or equipment for political activities. We prohibit the use of Company funds and assets to support political candidates, parties or ballot measures. As a Company, we comply with the laws related to contributing to, directly or indirectly, political organizations and government officials where appropriate. Under our Corporate Governance Principles, the Board is responsible for overseeing the process used by the Company to ensure the Company's policy prohibiting political contributions is effectively implemented.

The Company made no political contributions in 2022 but does hold membership in recognized and reputable industry groups that may conduct lobbying activities. West supports trade associations to advance collaborative approaches to problems faced by companies engaged in the same industries that we are in, but our support does not extend to use of our funds to support any candidate, party or ballot measure. We also monitor the major policy positions taken by these associations to ensure they are consistent with our positions.

------

Anti-Hedging and Pledging Policies

We prohibit directors, officers and team members from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, which would allow them to continue to own our common stock, but without the full risks and rewards of ownership. We also prohibit directors, executive officers and other senior team members from engaging in pledging or hypothecating our securities as collateral for a loan without demonstrating to the General Counsel that a director or officer has the financial capacity to repay the loan. It is expected that this exception would be permitted only in exceedingly rare circumstances. We have never granted an exception or waiver to these policies. No pledging is permitted to cover margin debt. Additionally, no West securities may be held in a margin account by directors or officers because there is a risk of the shares being sold without consent. Directors and officers are prohibited from engaging in short sales or other short-position transactions in West securities as well.

------

Share Ownership Goals

***Directors.*** To encourage significant share ownership by our directors and further align their interests with the interests of our shareholders, directors are expected to acquire within three years of appointment, and to retain during their Board tenure, shares of our common stock equal in value to at least five times their annual retainer. The directors elected prior to 2021 meet this requirement, including directors who are still within the initial three-year period. Ms. Joseph and Dr. Lockhart, who were appointed in August 2021 and July 2022 respectively, have not yet met the ownership goal, but are expected to do so during the required period.

***Officers.*** Share ownership goals further align an officer's interests with those of our shareholders and encourage a long-term focus. Within five years of attaining their position, all executive officers must acquire shares of common stock with a value equal to designated multiples of their base salary. The Compensation Committee established a goal of six times base salary for the CEO and two times base salary for all other named executive officers. A full description of the approved changes and the officer share ownership requirements can be found in our "*Compensation Discussion and Analysis.*"

DIRECTOR COMPENSATION

&nbsp;&nbsp;<br>Director Compensation<br>

2022 Non-Employee Director Compensation

Our Director compensation structure is reviewed annually by the Board in consultation with Pay Governance LLC ("Pay Governance"), our independent compensation consultant. The compensation structure in effect for 2022 is set forth below:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Compensation Item** | **Amount** |
| &nbsp;&nbsp;**Annual Retainers and Chair Fees** |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Board membership | $90000 |
| &nbsp;&nbsp;&nbsp;&nbsp;Chair of the Board |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Lead Independent Director | 40000 |
| &nbsp;&nbsp;&nbsp;&nbsp;Audit Committee Chair | 20000 |

| &nbsp;&nbsp;&nbsp;&nbsp;All Other Committee Chairs | 15000 |
| &nbsp;&nbsp;**RSUs** | 190000 |

---

Given the composition of the Board Leadership as of May 24, 2022, no additional chair fee was paid to Mr. Green in 2022. The Board determined that the Lead Independent Director should receive an additional $40,000 retainer, paid quarterly and subject to deferral under the Directors' Nonqualified Deferred Compensation Plan. Mr. Pucci's retainer for 2022 was prorated for the length of time he acted as Lead Independent Director. Mr. Buthman's retainer for 2022 was prorated for the length of the time he acted as Finance Committee Char.

The following table shows the total 2022 compensation of our non-employee directors.

Fees Earned or Paid in Cash

The amounts in the "Fees Earned or Paid in Cash" column are retainers earned for serving on our Board, its committees and as committee chairs and Chair, as applicable. All annual retainers are paid quarterly. Dr. Lockhart was appointed a Director on July 26, 2022, and, therefore received a partial third quarter retainer of $16,027. The amounts are not reduced to reflect elections to defer fees under the Director Deferred Compensation Plan. During 2022, Ms. Joseph deferred 100% of her fees.

DIRECTOR COMPENSATION

#### Stock Awards
The amounts in the "Stock Awards" column reflect the grant date fair value of stock-settled RSU awards made in 2022 and the grant date fair value as determined under Financial Accounting Standards Board Accounting Standards Codification ("FASB ASC") Topic 718. On May 24, 2022, each non-employee director was awarded 632 RSUs, with a grant date fair market value of $300.72 per share based on the closing price of our common stock on the award date. These awards had a grant date fair value of approximately $190,000. Upon Dr. Lockhart's appointment, he was awarded a prorated award for his service from August 1, 2022 to the next Annual Meeting of 454 RSUs with a grant date fair market value of $339.04 per share based on the closing price of our common stock on the award date. The prorated award had a grant date value of approximately $153,924. For a discussion on RSU grant date fair value, refer to Note 14 of the consolidated financial statements in our 2022 Annual Report.

RSUs are granted on the date of our Annual Meeting and fully vest on the date of the next Annual Meeting so long as a director remains on the Board as of that date. Generally, all unvested grants of equity forfeit upon termination. However, if a director retires during the calendar year that he or she reaches our mandatory retirement age, the award will vest on a monthly basis through retirement.

Stock-settled RSUs are distributed upon vesting, unless a director elects to defer the award under the Director Deferred Compensation Plan. In 2022, all directors elected to defer their awards with the exception of Mr. Buthman, Dr. Lockhart and Mr. Hofmann. All awards are distributed as shares of common stock, as described below. When dividends are paid on common stock, additional shares are credited to each director's deferred stock account as if those dividends were used to purchase additional shares.

The table below shows the number of outstanding stock awards held by each director at year-end. No directors have any outstanding options.

DIRECTOR COMPENSATION

#### Director Deferred Compensation Plan
All non-employee directors may participate in the Director Deferred Compensation Plan, which permits participants to defer all or a part of their annual cash compensation until their Board service terminates. Deferred fees may be credited to a "stock-unit" account that is deemed invested in our common stock or to an account that earns interest at the prime rate of our principal commercial bank. Stock-unit accounts are credited with DEUs based on the number of stock units credited on the dividend record date.

The value of a director's account balance is distributed on termination of Board service. The value of a director's stock-unit account is determined by multiplying the number of units credited to the account by the fair market value of our common stock on the termination date.

RSUs that a director elects to defer (and all shares of deferred stock) are distributed in shares of stock. Pre-2014 stock units may be distributed in cash in lieu of stock if a director made an election in 2013. All post-2013 stock units are only distributable in stock. Partial shares are distributed in cash.

Directors may receive their distribution as a lump sum or in up to ten annual installments. If a director elects the installment option, the cash balance during the distribution period will earn interest at the prime rate of our principal commercial bank and deferred stock and stock-settled units will be credited with DEUs until paid.

The following table summarizes the amounts credited to each Director Deferred Compensation Plan account as of December 31, 2022. All values on the following table are determined by multiplying the number of stock units or shares of deferred stock, as applicable, by $235.35, the fair market value of a share of stock on December 30, 2022. A portion of the stock units reported below may relate to deferred compensation that has previously been reported in the "Fees Earned or Paid in Cash" column for the year the underlying compensation was earned by the director.

Executive Summary: 2022 Performance at a Glance

West's long-term business strategy includes growing and expanding our products and services to meet the unique needs of our customer groups, operating with excellence to drive efficient utilization of our global manufacturing footprint and building the capabilities of our team to address current and future business needs. This strategy drives our long-term financial construct of high single digit organic sales growth annually and improved profitability year over year and, in turn, creates a sustainable business that will meet the needs of our customers, patients, shareholders and team members.

Each year, we have seen growing interest and demand for our high value product offerings, delivery device platforms and our services. Customers are also coming to West for our scientific expertise and insight into the regulatory landscape that governs our industry. This demand has translated into positive results for the business. In 2022, we reported:

● Full-year 2022 net sales of $2.887 billion, a 2.0% increase; organic net sales growth of 7.7%; currency translation decreased net sales growth by 570-basis points

● Full-year 2022 reported-diluted EPS of $7.73, a decrease of 10.8%, and full-year 2022 adjusted-diluted EPS of $8.58 remained unchanged from the prior year.

● Full-year 2022 operating profit margin of 25.4%, a decrease of 4.5%, and full-year 2022 adjusted operating profit margin of 26.4%, a decrease of 1.9%

● Full-year 2022 operating cash flow was $724.0 million, an increase of 24.0%; capital expenditures were $284.6 million, compared to $253.4 million over the same period last year, and represented 9.9% of full-year 2022 net sales; and free cash flow (operating cash flow minus capital expenditures) was $439.4 million, an increase of 32.9%

The foregoing discussion is qualified by the information contained in the performance graph in our 2022 Annual Report, the "Financial Measures and Adjustments" section beginning on page 55 of this Proxy Statement and our non-U.S. GAAP reconciliation set forth in the Form 8-K filed February 16, 2023.

---

Governance and Compensation

#### Executive Compensation Philosophy
Our compensation philosophy is to provide competitive executive pay opportunities tied to our short-term and long-term success. We follow a "market median" target compensation philosophy approach, reviewing each compensation component (base salary, target AIP and LTI Awards) against the market median. However, we focus on Target Direct Compensation ("TDC") at the market median to allow flexibility to target an individual's component and total compensation opportunity above or below the median based on individual performance, critical skills, and recognition of current and anticipated future contributions. This overriding pay-for-performance approach enables us to attract, motivate and retain the type of executive leadership that will help us achieve our strategic objectives and realize increased shareholder value. To achieve these goals, we have adopted the following program objectives:

● Reward achievement of both operating performance and strategic objectives

● Align the interests of West's leaders to those of our investors by varying compensation based on both short-term and long-term business results and delivering a large portion of the total pay opportunity in West stock. All NEOs have a minimum of 64% of at-risk compensation based on performance

● Differentiate rewards based on performance against business objectives to drive a pay-for-performance culture, with a major portion of executive pay based on achievement of financial performance goals

● Promote a balanced incentive focus that does not encourage unnecessary or unreasonable risk-taking

● Be market competitive to attract and retain highly qualified senior leaders needed to drive and grow a global enterprise

COMPENSATION DISCUSSION AND ANALYSIS

#### Targeted Pay Mix
The chart below illustrates the percentage weighting of each compensation element that comprises the 2022 target TDC for the CEO and the average for the other NEOs.

![Graphic](wst-20230425xdef14a_a036.jpg)

------

Factors Used in the Compensation Process

#### Compensation Committee
The Compensation Committee (or the "Committee" in this section of the Proxy Statement) reviews and approves the compensation elements and the compensation targets for each of our executive officers. The Committee also makes determinations with respect to the AIP as it relates to our executive officers, including the approval of annual performance goals and subsequent full-year achievement against those goals. It administers all elements of the Company's LTI plan, and approves the benefits offered to executive officers. Compensation decisions for the CEO are reviewed and approved by the full Board of Directors.

The Committee uses its judgment in making decisions about individual compensation elements and total compensation for our NEOs. This judgment is informed by competitive market data but primarily is focused on each NEO's performance against his or her individual performance objectives, as well as the Company's overall financial performance and the financial performance of the function or areas of operational responsibility for each NEO.

In making its decisions, and with guidance from our independent compensation consultant, Pay Governance, the Committee uses several resources and tools, including competitive market information, compensation trends within our comparator groups, where available, and realizable pay versus performance analysis.

The Committee also periodically reviews "tally sheets" for each of our executive officers as one of the tools to help assess the alignment of NEO pay with our performance and compensation philosophy. The tally sheets include salary, equity and non-equity incentive compensation and the value of compensation that would be paid in various termination scenarios. The tally sheets help the Committee to understand the magnitude and interplay of the various components of our compensation programs.

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

COMPENSATION DISCUSSION AND ANALYSIS

Finally, the Committee evaluates the Company's compensation programs on an annual basis to ensure that our plans do not induce or encourage excessive risk-taking by participants.

#### Management
Our CEO and CHRO annually review with the Committee the performance of each executive officer and recommend to the Committee annual merit salary adjustments and any changes in annual or long-term incentive opportunities or payouts for these officers, except for the CEO. The Committee considers Management's recommendations along with data and recommendations presented by Pay Governance.

The CHRO serves as the liaison between the Committee and Pay Governance, providing internal data on an as needed basis so that Pay Governance can produce comparative analyses for the Committee. In addition, the Company's Human Resources, Finance and Law Departments support the work of the Committee by providing information, answering questions and responding to various requests of Committee members as required.

#### Independent Compensation Consultant
The Committee has engaged Pay Governance as its independent consultant to assist the Committee in evaluating the executive compensation program. The consultant provides no services to us other than advice to the Committee on executive compensation matters (including CIC matters) and to our NCGC on director compensation. In 2022, the Committee reaffirmed Pay Governance to be independent from the Company under the applicable NYSE and SEC regulations.

During 2022, Pay Governance performed the following tasks for the Committee:

✔ Provided competitive market data for the compensation of the executive officer group and provided input to the Committee regarding officer pay recommendations (including the CEO)

✔ Assessed incentive plan performance difficulty of achievement and provided related context regarding performance metric selection

✔ Updated the Committee on executive compensation trends and regulatory developments

✔ Prepared a realizable pay analysis for the CEO

✔ Conducted an in-depth review of the Company's comparator groups

✔ Provided input on compensation program design and philosophy

✔ Monitored trends and analysis in executive and equity compensation

#### External Benchmarking
In support of our compensation philosophy, we reference the median compensation values of two compensation comparator groups, which we refer to as the "Business Segment Group" and the "Broad Talent Market Group." Data from both the Business Segment Group (which generally is applicable to the CEO and CFO) and Broad Talent Market Group (applicable to all Executive Officers) are used to determine competitive pay practices for our CEO and executive officers in a wholistic manner.

The Business Segment Group is composed of public companies with operational and customer characteristics like our own business operations. These companies initially are identified by Pay Governance and then approved by the Committee with input from Management based on the following criteria: (1) size (approximately one-half to two times our annual sales); (2) industry (healthcare equipment/supplies, industrial manufacturing and life sciences tools/services); and (3) operating structure such as:

● Global footprint with multi-plant manufacturing capabilities

● Similar raw materials and products (elastomers, plastics, metals), and similar intellectual property profile

50 \| 2023 Annual Meeting and Proxy Statement

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

COMPENSATION DISCUSSION AND ANALYSIS

● Similar customer characteristics (complex sales cycle, quality requirements, regulatory requirements)

The Broad Talent Market Group is a larger and broader sampling of size-appropriate companies that participate in the WTW (formerly Willis Towers Watson) annual executive compensation database. Unlike the Business Segment Group, the Committee does not select individual members of the Broad Talent Market Group. Companies within the Broad Talent Market Group operate in industries that are similar, but not identical to our own industry. Industries included are: Chemicals and Gases; Electrical and Scientific Equipment and Components; Medical Supplies and Equipment; and Pharmaceutical and Biotechnology.

Given our size and business portfolio, it is challenging to identify a robust sample of appropriate market compensation peers that fit conventional criteria. Therefore, we believe that using a balance of business and talent market references that reflect companies with which we compete for business and capital, and more broadly, those with which we compete for talent, provides the Committee with decision-quality data and context, and reasonably represents our labor market for executive talent.

The Committee believes it is good governance to periodically review our two compensation comparator group approach and comparators to ensure they are appropriate and to adjust based on: (1) our changing enterprise strategy; (2) the markets in which we compete for business, including emerging or more technical markets; (3) the areas in which we compete for talent, business and capital; and (4) our changing size and complexity. The last significant update to our comparator groups occurred in 2021.

Below is a chart that lists each company included in the current Business Segment Group and some key data the Committee considered in making the selection for inclusion. The sales data below are generally from 2022 public annual reports with respect to each company, with average market capitalization data as of December 31, 2022. All amounts are in millions of U.S. Dollars.

We have designed our compensation programs to align the pay of our senior executives with both short-term and long-term financial results and the performance of our stock. As such, the majority of pay for our CEO and other NEOs is performance-based and is impacted by our financial results and stock price performance. During 2022, 16% of Mr. Green's Total Direct Compensation ("TDC") was variable based on short-term business performance and 71% was based on long-term goals. For our other executives, approximately 19% of their TDC was variable based on short-term business performance and 53% was based on long-term goals.

Target achievement of financial metrics for 2022 resulted in a payout less than 100% for our short-term incentive plan and a payout above 100% of our long-term incentive plan.

Our AIP paid out at 50.7% of target for the Corporate plan.

Our 2020-2022 performance period LTI plan is equally based on achieving sales CAGR and ROIC targets. The payout for the performance period was 200%, driven by overperformance in both metrics. The sales CAGR for this period achieved 17.5% versus the 7.5% target resulting in a 200% payout factor, which is weighted 50% (contributing 100% to the payout), and our ROIC for this period achieved 21.78% of the target of 14% resulting in a 200% payout factor, which is also weighted 50% (contributing 100% to the payout).

COMPENSATION DISCUSSION AND ANALYSIS

Incentive Compensation: Important Facts About Our Incentive Targets

As in previous years, the Committee evaluates and decides upon the appropriate financial measures to be considered in determining compensation payouts using the following principles:

● Alignment with our growth strategy, supporting profitable growth while generating significant cash from operations, and driving long-term value creation for our customers, team members, investors and shareholders

● Provide a clear line of sight to the stated goals of the Company, so that the targets are clearly understood and can be affected by the performance of our executives and team members

● Attainable targets, but with a sufficient degree of "stretch" to support growth

● Consistent with market practice

● Currency neutral on sales in order to measure the underlying results of the business and help to ensure business leaders are making decisions that drive long-term sustainable growth rather than addressing short-term currency fluctuations or items impacting comparability

● We make limited adjustments to metrics. At times, adjustments may need to be made when calculating results for awards such as for changes in financial accounting reporting regulations, unexpected changes in costs and other financial implications associated with corporate transactions

We continually test the robustness of our incentive targets and performance payout curves. The setting of our performance payout curves considers the following:

● Performance levels necessary to achieve our long-term goals and deliver superior shareholder returns

● The difficulty of achieving various levels of performance based on historical and anticipated future results

● Metrics, program designs and results at companies in our Business Segment Group

● Performance relative to our Business Segment Group and anticipated industry trends

The Committee annually reviews the target setting process to ensure adherence to our principles. This analysis is aided by a retrospective review of our performance compared to that of our competitors and is performed annually by the Board's independent compensation consultant, Pay Governance.

For 2022, we measured the following key financial metrics:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Plan** | &nbsp;&nbsp;**Financial Metric** | &nbsp;&nbsp;**Rationale** |
| AIP | Earnings per Share | A comprehensive measure of income and provides an emphasis on profitable growth while focusing managers on expense control |
| AIP | Consolidated Net Sales | Provides a clear line of sight target for all members of our Executive Leadership Team as we strive to create value by growing our sales |
| AIP | Operating Cash Flow | Provides a focus on generating cash in the short term to fund operations, research and capital projects and focuses managers on cash generation |
| AIP | Consolidated Gross Profit | Provides a focus on targeting efforts on higher value product growth and improving operating efficiencies in our production facilities |
| LTI | Sales Compounded Annual Growth Rate | Provides an objective measure of net sales growth |
| LTI | Return on Invested Capital | Drives efficient and disciplined deployment of capital |

---

*Note: All metrics are measured at actual foreign currency exchange ("FX") rates except for Consolidated Net Sales, which is measured at budget FX rates to remove the impact of currency fluctuations and allow for a year to year comparison.*

COMPENSATION DISCUSSION AND ANALYSIS

Our Annual Incentive Compensation

#### Target Setting
At the beginning of each year, the Committee and the Board review and approve West's annual business objectives and set the metrics and weightings for the AIP to reflect current business priorities. These objectives translate to targets for West and for each business unit for purposes of determining the target funding of the AIP. Performance against business objectives determines the actual total funding pool for the year, which can vary from 0% to 200% of total target incentives for all executives.

Our reported results may be adjusted when comparing to AIP targets for unusual events outside the control of Management including changes in accounting standards, tax regulations and currency devaluations. We may also exclude certain transactions such as material acquisition or disposition costs including restructuring charges, particularly if these items were not included in the performance target. The specific adjustments reviewed and made by the Committee in 2022 are listed in the *"Financial Measures and Adjustments"* section of this Proxy Statement, and include adjustments for foreign currency exchange (revenue only), stock-based compensation tax benefits, restructuring charges and amortization on acquisition intangibles.

#### Target Awards
The target annual incentive awards for our NEOs are set as a percentage of base salary. Target awards are reviewed annually to ensure alignment with our compensation philosophy of targeting each compensation element and the Target Direct Compensation at the market median. Variances from this goal are based on an evaluation of competitive market data, internal equity considerations and individual performance. Our payout curve is structured to reflect our philosophy that Management should be rewarded for meeting or exceeding goals and payouts should diminish or be withheld when targets are missed.

The formula to determine each NEO's AIP total potential payment is as follows:

![Graphic](wst-20230425xdef14a_a037.jpg)

The payout factor is a pre-established multiplier that corresponds, on a sliding scale, to the achievement percentage of the AIP target objective so that if actual performance is less than target, the multiplier decreases on a sliding scale based on the achievement percentage and is based on the following chart:

---

| | |
|:---|:---|
| &nbsp;&nbsp;**Achievement %** | **Payout factor** |
| &nbsp;&nbsp;<85%  | 0.00% |
| &nbsp;&nbsp;85% | 50.00% |
| &nbsp;&nbsp;95% | 83.35% |
| &nbsp;&nbsp;100% | 100.00% |
| &nbsp;&nbsp;105% | 133.33% |
| &nbsp;&nbsp;110% | 166.67% |
| &nbsp;&nbsp;≥115% | 200.00% |

---

Achievement that falls between any two achievement percentages is straight-line interpolated. The Committee has the discretion to adjust payouts positively or negatively to account for exceptional circumstances.

The Committee reviews the AIP scoring, adjustments made thereto and approves the AIP funding level.

Financial Measures and Adjustments

EPS growth for AIP purposes differs from the EPS reported in our Earnings Release under U.S. GAAP and is best explained by reconciling the results used for calculating AIP payments to U.S. GAAP and the Earnings Release. A reconciliation of the financial measures used for the AIP to our Earnings Release financials allows for a meaningful comparison. The following table contains unaudited reconciliations of 2022 U.S. GAAP Consolidated Net Sales, OCF and Reported-diluted EPS to Adjusted Net Sales, Adjusted OCF and Adjusted-diluted EPS for AIP purposes relating to the 2022 AIP Performance Metrics and Achievement Table above. There were no other adjustments.

COMPENSATION DISCUSSION AND ANALYSIS

Our Long-Term Equity Incentive Compensation

#### Target Setting
Typically, the targets for West's PSUs are set at the beginning of each three-year performance period, considering West's financial guidance and the annual budget as approved by the Board. At the end of the three-year period, the score is calculated based on results against the predetermined, equally-weighted targets. We use CAGR and ROIC as our performance measures for determining PSU payouts. Each metric is weighted equally because we believe sales CAGR and ROIC are equally important in creating shareholder value over the long-term.

The metrics, goals and weightings for the performance period are:

2022—24 PSU Performance Period Targets

---

| | | | |
|:---|:---|:---|:---|
| &nbsp;&nbsp;**Metric** | **Threshold** | **Target** | **Maximum** |
| &nbsp;&nbsp;CAGR | 6.37% | 9.10% | 18.20% |
| &nbsp;&nbsp;ROIC | 16.94% | 24.20% | 48.40% |

---

#### Target Awards
LTI compensation opportunities for our executives, including the NEOs, are entirely equity-based. Each NEO's annual target award is split into two equal amounts, which are then used to determine the number of stock options and PSUs awarded to the executive. The value of each stock option is determined under the Black-Scholes valuation method. The value of each PSU is determined by our stock price at the grant date. The actual or realized value of these awards in future years will vary from this target amount based on share price, ROIC and sales CAGR performance over time.

The use of stock options is intended to align our executives' longer-term interests with those of our shareholders because options deliver value to the executive only when and to the extent that share price exceeds the exercise price of the option. Therefore, options provide a strong performance-based link between shareholder value and executive pay.

PSUs entitle the recipient to receive common shares based on achievement of three-year sales CAGR and ROIC targets, which, if achieved, will have resulted in strong returns for our shareholders.

The value of each NEO's long-term grant is determined by the Committee based on its review of peer-group market data, the executive's role and responsibilities, his or her impact on our results, advancement potential, retention considerations and, in principle, is targeted to the market median.

In 2022, the number of target PSUs awarded to all executives, including the NEOs, was calculated by dividing the PSU portion of the annual target award value by $369.13, the closing price of our stock on the day the target awards were approved by the Committee, February 22, 2022. Mr. Birkett's additional PSU awarded was calculated by dividing the PSU portion of the additional annual target award value by $303.34, the closing price of our stock on the day the award was approved by the Committee, May 23, 2022. Please refer to Note 14 of our Annual Report on Form 10-K for a complete discussion of our stock-based compensation.

#### Performance Share Units
The number of shares earned under the PSUs is based on achievement of sales CAGR and ROIC targets. Each PSU award agreement contains a target payout for the recipient. The number of shares an executive earns at the end of a performance period is calculated by multiplying the target number of PSUs awarded at the beginning of the period times the applicable "payout factor" for each performance metric by the weighting for that performance metric.

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;≥150% | 200% |

---

The Committee approves the determination of actual achievement relative to pre-established targets and the number of PSUs is adjusted up or down from 0% to 200% based on the approved actual achievement. The Committee reserves the right to adjust payouts negatively or positively under exceptional circumstances.

#### Equity Award Grant Practices
Under the Committee's equity-based awards policy and procedures, equity awards to NEOs normally are made once per year. The Company's policy on equity grants contains rules on determining (1) the grant date of equity awards (at least two business days following the release of our annual results for the preceding fiscal year) and (2) the exercise price of stock options granted by the Committee (which must be at least equal to the closing price of our stock on the grant date).

2022 Compensation Decisions

In the first quarter of each year, the Committee meets to determine CEO and Executive Officers' pay decisions for base salary, AIP and LTI award grants reflecting both prior year performance and appropriate positioning versus the representative peer group(s).

Our compensation strategy supports West's business imperatives. It is designed to ensure:

● That executives balance short-term objectives against long-term priorities

● Alignment with shareholder interests

● The Company can attract and retain the leadership needed to deliver strong results

#### 2022 Compensation Decisions for Our CEO
The Chair of the Committee works directly with the Committee's Compensation Consultant to provide a decision-making framework for use by the Committee in determining incentive plan payouts and setting target compensation opportunities for the CEO. This framework considers, among other things:

● Assessment of the CEO's performance against objectives in the prior year, both qualitative and quantitative

● Progress against strategic objectives

● West's total performance over a multi-year period

● Competitive benchmark analysis, and other relevant information

During 2022, all NEOs were eligible to participate in our defined contribution retirement plan for all team members. In addition to the standard benefits available to all eligible team members, we maintain nonqualified retirement plans in which these executives participate in the same capacity as eligible salaried team members.

All tax-qualified defined benefit plans have a maximum compensation limit and a maximum annual benefit, which limits the benefit to participants whose compensation exceeds these limits. The nonqualified retirement plans offered by the Company provide benefits to key salaried team members, including each NEO, using the same benefit formulas as the tax-qualified plans but without regard to the compensation limits and maximum benefit accruals for tax-qualified plans.

#### Severance Plan Arrangements
West also provides our NEOs with benefits upon termination in various circumstances, as described under "Estimated Payments Following Termination" and "Payments on Termination in Connection with a Change-in-Control" sections below.

The purpose of the Executive Change in Control Severance Pay Plan is to provide compensation in the case of termination of employment in connection with an acceleration event. The Executive Change in Control Pay Plan applies to all of our NEOs with the exception of Mr. Green. The severance terms for Mr. Green in the event of an acceleration event were covered under his employment agreement. The provisions of this plan are specifically designed to address the inability of senior executives to influence the Company's future performance after certain change of control events. We believe that our existing arrangements help executives remain focused on our business in the event of a threat or occurrence of a change in control and encourage them to act in the best interests of the shareholders in assessing and implementing a transaction. The Company's CIC agreements do not include excise tax gross ups and single triggers where benefits would be paid without a termination of employment. Additionally, our CIC agreements include a cutback in payments and benefits if the NEO would be in a more favorable after-tax position and provide that no benefits are payable upon a voluntary resignation that is not due to "good reason."

With regard to Mr. Green's severance arrangement, we believe severance pay is necessary to attract and retain a quality CEO candidate and that the benefits of securing a release of claims, cooperation and non-disparagement provision from Mr. Green upon an involuntary termination are significant. Mr. Green has a separate employment agreement that contains many provisions similar to those contained in the form of CIC Agreement for other officers, but also includes other terms and conditions that resulted from negotiations relating to compensation and termination.

The terms and conditions of all these agreements are described in more detail in the Compensation Tables section of this Proxy Statement.

The Committee approved a U.S.-based severance plan to provide a period of transition for senior executives who are separated without cause. The terms are consistent with those for all U.S. salaried team members and the length of severance benefit is dependent upon years of service and job level. For officers, the severance payment is equal to one year's salary and benefits continuation at active participant rates, provided the officer has a minimum of one year of service. In addition, all team members are eligible for job transition assistance. To receive benefits under the plan, team members must agree to certain restrictive covenants and a waiver of all claims against West.

#### Personal Benefits
The benefits provided to our NEOs are generally the same as or consistent with those provided to our other salaried team members. However, upon hire, Mr. Birkett, an Irish citizen, was provided tax planning and preparation reimbursement up to $15,000 per year (not subject to gross-up). This was due to a unique challenge regarding his change from an expatriate package at his prior employer to a local hire at West, as well as complications due to the relocation of a non-U.S. citizen. 2022 was the last year for this benefit.

COMPENSATION DISCUSSION AND ANALYSIS

#### Retention Cash
Occasionally, the Committee pays signing and retention bonuses in cash. These bonuses may have repayment obligations. The primary purpose of these payments is to replace equity or cash payments a new officer will forfeit from his or her former employer upon joining West.

#### Realizable Pay Analysis
The Committee works with Pay Governance to review pay granted and realizable by the CEO in the context of West's performance. Realizable pay is calculated using actual bonuses earned, end of period stock values and in-the-money value of stock options granted during the year. It takes a retrospective look at pay versus performance. The analysis showed that there was a high correlation between the realizable pay earned by our CEO and the Company's performance as measured by total shareholder return, sales CAGR, ROIC and similar financial metrics compared to other members in our Business Segment Group. The Committee determined this analysis is consistent with its pay-for-performance philosophy and that our incentive plans are operating as intended.

#### Risk Considerations in Our Compensation Programs
The Committee, in consultation with our internal auditor and our independent compensation consultant, has reviewed our compensation policies and practices for our officers and team members and concluded that any risks arising from these policies and programs are not reasonably likely to have a material adverse effect on the Company. The Committee believes that the mix and design of the elements of our compensation program are appropriate and encourage executive officers and key team members to strive to achieve goals that benefit the Company and our shareholders over the long term.

Our compensation policies and procedures are applied uniformly to all eligible participants. By targeting both company-wide and business-unit performance goals in our annual bonus plans and long-term compensation, we believe we have allocated our compensation between base salary and short- and long-term target opportunities in a way that does not encourage excessive risk-taking by our team members.

#### Policy on Hedging and Pledging
We prohibit directors, officers and team members from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, which would allow them to continue to own our common stock, but without the full risks and rewards of ownership. We also prohibit directors, NEOs and other senior team members from engaging in pledging, short sales or other short-position transactions in our common stock.

#### Impact of Tax and Accounting Treatment
The Committee selects compensation vehicles that will, in its view, create the best link between pay and performance. Generally, the accounting and tax treatments of executive compensation has not been a significant factor in the Committee's decisions regarding the amounts or types of compensation paid. Our programs have been designed to maximize deductibility under applicable tax law unless it conflicts with our compensatory goals. The Committee also considers the impact of changes to accounting regulations and tax law when reviewing elements of compensation, including equity and other performance-based awards.

&nbsp;&nbsp;&nbsp;&nbsp;(1) These amounts are an estimate of the increase in actuarial present value of each of our NEO's age 65 accrued benefit under our retirement plans for 2022. Amounts are payable only when a participant's employment terminates and may be reduced if benefits are commenced prior to age 65. Assumptions underlying the estimates are described under the 2022 Pension Benefits Table. This column does not include negative amounts. However, Mr. Green had a negative amount of $119,829.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Ms. MacKay was not a NEO when she joined the Company in December 2020.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Ms. Reiss-Clark was appointed an NEO in April 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(1) All options are exercisable in 25% annual increments beginning one year from the grant date, except as noted in footnote 5 for Mr. Green.

&nbsp;&nbsp;&nbsp;&nbsp;(2) RSUs were granted to Mr. Abraham as a recognition award on October 29, 2020. Vesting of awards for Mr. Abraham are discussed in footnotes 6. All RSUs granted also earn DEUs, which are subject to the same vesting schedule as the underlying RSU.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Bonus Incentive Awards are time-vesting restricted incentive shares granted when a NEO elects to receive a portion of his or her bonus in stock, whether or not the bonus is deferred under the Employee Deferred Compensation Plan. The restricted incentive shares were granted on March 1, 2019 to Mr. Birkett and Mr. Abraham and in each case, are 100% vested four years from the grant date if the bonus share to which the incentive share relates has not been sold and the team member has not terminated employment. The incentive shares will also vest 25% per year upon retirement, but no NEO who currently has outstanding incentive shares is yet eligible to retire. Unvested incentive shares are forfeited on employment termination. Dividends are paid on all unvested restricted shares and reinvested as additional stock subject to the same vesting requirements as the underlying shares. The market value of all restricted shares and RSUs is based on the closing price of our common stock on December 31, 2022 of $235.35.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Except as noted for Ms. MacKay who received PSUs on her hire date, these PSUs were awarded on February 19, 2019, February 18, 2020 and February 23, 2021, and each covers a three-year performance period. This table includes as outstanding the 2019-21 PSUs awards that were distributed in February 2022, because the performance is not actually determined and certified by the Committee until the first quarter of 2022. The 2020 and 2021 awards will be earned (if at all) on December 31, 2022 and December 31, 2023, respectively, subject to the satisfaction of the applicable performance criteria and generally subject to the recipient's continued employment through those dates. As required by the SEC's

disclosure rules, because the performance for the most recently completed fiscal year was more than 100%, the number of PSUs shown assumes that a maximum payout of 200% will be achieved for all three awards. Fair market value of the unearned PSUs is based on the closing price of our common stock on December 31, 2022 of $235.35. The amounts are not reduced to reflect any elections to defer receipt under the Employee Deferred Compensation Plan.

&nbsp;&nbsp;&nbsp;&nbsp;(5) The options denoted as Hire Grant 1 for Mr. Green in the table above vested 57.1% on April 24, 2018. The remaining 42.9% of these retention options and shares vested on April 24, 2020. The options denoted as Hire Grant 2 for Mr. Green were 25% vested upon the grant date and the remaining options vested in 25% increments on February 24th of each following year. The options denoted as Hire Grant 3 for Mr. Green vested in 25% increments on February 23rd of each year following grant. All other option grants are subject to the vesting schedules set forth in footnote 1 above.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Mr. Abraham received 454 retention RSUs on October 29, 2020 which will vest 100% on the fourth anniversary of the grant date. The RSUs will vest provided that he remains employed by the Company, or dies or becomes disabled. The options awarded on October 29, 2020 as part of a retention award will vest in 25% increments on the anniversary of the grant.

&nbsp;&nbsp;&nbsp;&nbsp;(7) Upon Ms. MacKay's hire on December 2, 2020, she was awarded 2,360 stock options. She was also granted 272 PSUs for performance period 2019-2021 and 272 PSUs for performance period 2020-2022. Ms. Mackay received 1,003 PSUs as part of her annual award on February 23, 2021 related to the performance period 2021-2023. Although awarded in December 2020, all PSUs vest on the normally applicable vesting schedule described in footnotes 1 and 4.

#### 2022 Option Exercises and Stock Vested
The following table provides information about the value realized by our NEOs on the vesting of stock awards and units during 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The value realized is equal to the difference between the option exercise price and the fair market value of our common stock on the date of exercise, multiplied by the number of options exercised.

&nbsp;&nbsp;&nbsp;&nbsp;(2) This column includes PSUs that were awarded in 2019 and earned in 2021, and paid in 2022 to all NEOs, whether or not either award was deferred under the Employee Deferred Compensation Plan. This column includes partial vesting of Mr. Birkett's new hire RSU award. For RSUs and PSUs, the total includes additional shares awarded pursuant to DEUs, which are credited on unvested PSUs over the three-year vesting period at a rate that assumes the participant will earn the target award. For PSUs, at the time of the payout, the credited DEUs are then increased or decreased based on the payout factor earned for the applicable three-year performance period. Because the payout factor earned for the 2019-21 performance period was 189.25%, the number of DEUs accrued over that period was multiplied by 189.25%. The following table shows the PSU payouts that vested, and the number of additional shares distributed due to DEUs.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The value of the PSUs was determined by multiplying the number of vested units by $369.13, the fair market value of our common stock on the payout date, February 22, 2022. The value of the RSUs for Mr. Birkett was determined by multiplying the number of vested units by the fair market value of our common stock on June 21, 2022.

#### 2022 Pension Benefits

#### Qualified Retirement Plan
Until December 31, 2006, we maintained a final average pay defined benefit pension plan, which calculated retirement benefits for all salaried participants as a percentage of average annual earnings. Each participant's accrued benefit under the Retirement Plan's pension formula was frozen, and the pension benefits related to service on or after January 1, 2007 for all existing and new participants are expressed as a "cash balance" type formula. Under the cash balance approach, an allocation is made at the end of each calendar year (or on employment termination, if earlier) to a participant's hypothetical cash balance account. The allocation is determined by the age of the participant and the percentage of annual compensation for that age band pursuant to the basic cash balance formula.

Each year, the balance in the hypothetical account will be credited with interest at a rate equal to the average 30-Year Treasury Bond Rate for November of the year prior to the year the interest is credited or 3.3%, if greater.

In general, the compensation used for determining a participant's benefits under the retirement plan consists of base salary, overtime, annual incentive awards (paid in cash or stock), and other cash remuneration, plus a participant's contributions to our 401(k) plan.

We froze pay credits to the Retirement Plan as of December 31, 2018. Only interest credits will continue to accrue on previously accrued benefits for eligible participants on January 1, 2019 and beyond. No team members hired on or after January 1, 2017 are eligible for the Retirement Plan. In lieu of the Retirement Plan benefits, we have made enhancements to our 401(k) plan, including a non-elective contribution, which is currently 3% of a participant's compensation, subject to applicable Code limits and vesting requirements. Effective August 31, 2021, we made the decision to terminate the Retirement Plan. A request for approval of the Plan termination was submitted to the Pension Benefit Guaranty Corporation ("PBGC"). With PBGC's approval, proceedings to terminate the Plan started in 2021 and concluded in 2022.

#### Supplemental Executive Retirement Plan
2022 IRS requirements limit the compensation that can be used to calculate a participant's benefit under a qualified retirement plan to $290,000 and the annual benefit is limited to $230,000. The SERP benefits are substantially equal to the difference between the total benefit accrued under the Retirement Plan and the amount of benefit the Retirement Plan is permitted to provide under the statutory limits on benefits and earnings. The benefits are unfunded and paid out of our general assets. SERP benefits (other than interest credit accruals) froze in a similar manner to the freeze to the Retirement Plan in January 2019.

The SERP provides for benefits accrued on or after January 1, 2005 to be payable in a lump sum on the date that is six months following termination of employment. Benefits accrued before that date are payable at the same time and in the same form as under the Retirement Plan. SERP benefits may be reduced to reflect early commencement of benefits before age 65. The SERP was closed to new entrants effective January 1, 2017.

COMPENSATION TABLES

**2022 Pension Benefits** 

The following table shows the present value of accumulated pension benefits that Mr. Green is eligible to receive under the SERP. As noted above, the Retirement Plan was terminated. The other NEOs are not eligible for and did not accrue benefits under either plan. Actual benefit present values will vary from these estimates depending on many factors, including an executive's actual retirement age, future-credited years of service, form of payment election, applicable interest rates and regulatory changes.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The present value assumes that Mr. Green retires at age 65 for purposes of the SERP. The assumed cash balance crediting rate is 3.3% in the SERP (crediting rate for Retirement Plan uses prior 5-year average and increased to 3.31% after plan termination date). The discount rate and post-retirement mortality assumptions used in estimating the present values of Mr. Green's accumulated pension benefit are set forth below.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Mr. Green received a lump sum distribution of the amount in this column upon the Retirement Plan termination in July 2022.

The form of payment assumption is 60% lump sum and 40% annuity payments. |

#### 2022 Nonqualified Deferred Compensation
The Employee Deferred Compensation Plan allows highly compensated team members to defer up to 100% of salary and cash bonus. Deferred cash contributions may be invested in a selection of investment options that mirror the funds available under our 401(k) plan.

With respect to team member contributions made before 2019, we matched them at the rate of 100% of the first 3% of salary deferrals, plus 50% of the next 2%, and employer matching contributions are 100% vested. Matching contributions ceased effective January 1, 2019. A non-elective contribution is also made on behalf of participants who exceed the applicable Code limits. Before 2019, participants were eligible to defer payout of annual bonus shares. We contributed one restricted incentive share for each four bonus shares deferred. PSUs remain eligible for deferral.

Incentive shares will vest on the fourth anniversary of the date of contribution or will vest pro rata on retirement, death or disability, if earlier. During the time these awards are deferred, they are deemed invested in our common stock and receive additional credits for DEUs. All deferred stock awards are distributed in shares of common stock.

Amounts deferred in any year, except for matching contributions on cash contributions, will be distributed automatically in a lump sum five years after the year of deferral. A participant may choose to defer these amounts to another date or until termination. Matching contributions are only distributed on termination. Participants may elect to receive distributions on termination in a cash or stock lump sum or up to ten annual installments.

Information regarding NEO's account balances in the Employee Deferred Compensation Plan is below.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The amounts reported in this column are reflected in this year's Salary column of the Summary Compensation Table ("SCT").

&nbsp;&nbsp;&nbsp;&nbsp;(2) These amounts reflect non-elective contributions made on behalf of participants who exceeded the applicable Code limits in the Employee Deferred Compensation Plan.

&nbsp;&nbsp;&nbsp;&nbsp;(3) These amounts reflect the net gains attributable to the investment funds in which the executives have chosen to invest and for deferred shares of stock contributed to the Employee Deferred Compensation Plan, net of any distributions or transfers.

&nbsp;&nbsp;&nbsp;&nbsp;(4) The total balance includes amounts contributed for prior years which have all been previously reported in the SCT for the year those amounts were deferred.

#### Payments on Disability
Each current NEO has long-term disability coverage, which is available to all eligible U.S. team members. The coverage provides full salary continuation for six months and thereafter up to 60% of pay with a $25,000 monthly limit. Eligible U.S. team members will earn cash balance pay credits until 2019. Team members who are vested in our Retirement Plan also receive continued medical coverage while on disability. Deferred compensation is payable according to the executive's election. Outstanding unvested stock options granted annually under our LTIP would be forfeited and outstanding vested stock options would be exercisable for the term of the option. Outstanding PSUs and unvested incentive shares would be forfeited when a team member becomes disabled. Lastly, the new hire and recognition RSUs and options granted to Mr. Birkett and Mr. Abraham will vest upon disability.

#### Payments on Death
Each current U.S.-based NEO has group life insurance benefits that are available to all eligible U.S. team members. The benefit is equal to one year's salary with a maximum limit of $500,000, plus any supplemental life insurance elected and paid for by the NEO. Deferred compensation is payable according to the executive's election on file. Outstanding unvested stock options granted annually under our LTIP, PSUs and incentive shares would be forfeited, and outstanding vested stock options would become exercisable for the term of the option.

The new hire and recognition stock, RSUs and/or options granted to Mr. Birkett and Mr. Abraham will also vest upon death.

#### Estimated Payments Following Termination
We have an agreement with Mr. Green that entitles him to severance benefits on certain types of employment terminations not related to a CIC. All other NEOs are not covered by an employment agreement, but are eligible for the Company's U.S.-based severance plan and consistent with those for all U.S. salaried team members, with the severance benefit dependent upon years of service and job level. For officers, the severance payment is equal to one year's salary and benefits continuation at active participant rates, provided the officer has a minimum of one year of service. In addition, all team members are eligible for job transition assistance. To receive benefits under the plan, team members must agree to certain restrictive covenants and a waiver of all claims against West.

COMPENSATION TABLES

#### Mr. Green
Mr. Green has an employment agreement that entitles him to continuation of his salary and welfare benefits at active team member rates for a period of 12 months if he is terminated involuntarily other than for "Cause" or the Company gives notice to Mr. Green that it will not renew the term of his employment under the agreement. Mr. Green's employment agreement does not entitle him to severance payments or continued benefits if his employment is terminated for Cause or because of his death or disability (except as described above).

"Cause" means any willful failure by Mr. Green to perform his duties or responsibilities or comply with any valid and legal directives of the Board; act of fraud; embezzlement; theft or misappropriation of the funds of the Company by Mr. Green; or Mr. Green's admission to or conviction of a felony or any crime involving moral turpitude, fraud, embezzlement, theft, or misrepresentation; Mr. Green's engagement in dishonesty, illegal conduct or misconduct that is materially injurious to the Company; Mr. Green's breach of any material obligation of any written agreement with the Company; or a material violation of a rule, policy, regulation, or guideline imposed by the Company or a regulatory body.

The obligation to pay severance is contingent on Mr. Green's execution of a release and other customary provisions, including compliance with non-competition, non-solicitation and confidentiality obligations contained in the agreement.

#### Other NEOs
The RSUs that Mr. Birkett received as a new hire award will vest: (1) in the event of termination other than for Cause; or (2) due to Good Reason. The definitions of "Cause" and "Good Reason" are substantially the same for all three awards. The RSUs that Mr. Abraham received will only vest early upon death or disability.

"Cause" means (1) an act or acts of dishonesty taken by an NEO; (2) repeated failure by an NEO to perform his or her duties and obligations, which are demonstrably willful and deliberate on the NEO's part and which are not remedied after the receipt of written notice from the Company; (3) the NEO's conviction of a felony; or (4) the NEO's intentional breach of the COC, which is materially and demonstrably injurious to the Company.

"Good Reason" means the occurrence of any of the following without the NEO's consent: (1) a material diminution in the NEO's base salary; (2) a material reduction in the NEO's duties, authority or responsibilities relative to the NEO's duties, authority and responsibilities in effect immediately prior to such reduction; or (3) the relocation of the NEO's principal place of employment in a manner that lengthens by fifty (50) or more miles the NEO's one-way commuting distance to the NEO's place of employment; provided that a termination shall only be for Good Reason if: (a) within forty-five (45) calendar days of the initial existence of Good Reason, the NEO provides written notice of Good Reason to the Company; (b) the Company does not remedy said Good Reason within thirty (30) calendar days of its receipt of such notice; and (c) the NEO terminates employment within sixty (60) calendar days after the expiration of such 30-day remedy period.

#### Estimated Additional Severance Payments
The table below reflects amounts that eligible executives would receive on termination of employment for certain reasons, other than following a CIC. No NEO will receive any enhanced benefit because of a termination for Cause. The amounts do not include amounts payable through a plan or arrangement that is generally applicable to all salaried team members, including equity acceleration values to the extent they apply to all LTIP participants. Under the severance plan, effective

#### Payments on Termination in Connection with a Change-in-Control
We have entered into agreements with each of our U.S.-based NEOs, as well as certain other of our officers, which provide the benefits described below on qualifying terminations of employment in connection with or within two years following a CIC.

All currently employed NEOs except Mr. Green have CIC Agreements that are substantially similar and include the following:

● Cash severance pay equal to two times the sum of the executive's highest annual base salary in effect during the year of termination and their target bonus immediately preceding the CIC

● Immediate vesting of any unvested benefits and matching contributions under our 401(k) plan and the Employee Deferred Compensation Plan as of the termination of the executive's employment

● Payment of short-term incentive compensation with respect to the period during which the termination occurs at target levels, prorated for number of days worked in the year

● Immediate vesting of all unvested stock options, stock appreciation rights ("SARs"), shares of stock, stock units, and other equity-based awards at target levels

● Continued medical, dental, life, and other benefits for 24 months after termination of the executive's employment, or until his or her retirement or eligibility for similar benefits with a new employer

● Payments will be reduced below the applicable threshold in the Code if the NEO would be in a better after-tax position than if the excise tax under Section 4999 of the Code applied

● Outplacement assistance up to $50,000

The severance payments are payable in monthly installments and if the executive is a key employee at the time of his/her termination, payments will be delayed six months to the extent required by applicable tax law.

COMPENSATION TABLES

Employment terminations that entitle these executives to receive the severance benefits under a CIC consist of: (1) resignation following a constructive termination of his or her employment; or (2) employment termination other than due to death, disability, continuous willful misconduct, or normal retirement. These terminations must occur within two years after a CIC.

To receive the severance benefits under the agreement, an executive must agree not to be employed by any of the Company's competitors or compete with the Company in any part of the United States for up to two years following employment termination for any reason and execute a release of claims in favor of the Company.

Mr. Green has a separate employment agreement, with CIC provisions that are substantially similar to the provisions contained in the other NEO agreements except for the following:

● His payment is two times the sum of his annual base salary plus average of his bonus over the prior three years

● 36-months of benefit continuation instead of 24 months

● Mr. Green's benefits may be reduced in the event he retires

● His agreement does not contain specific language regarding the satisfaction of performance goals for incentive compensation, or a payout of the short-term incentive compensation for the year of termination

● The definition of a CIC set forth below requires a change in two-thirds of our Board members rather than three-fourths

● The definition of "Cause" and "Constructive Termination," which is called "Good Reason," are slightly different and set forth in his employment agreement, which is described under Post-Employment Compensation Arrangements on page 63

**Definitions used in the CIC Agreements**

The definitions below apply to all agreements, except as specifically noted above for Mr. Green.

*Definition of "Change-in-Control."* For each agreement, a CIC includes any of the following:

● Any person or entity other than us, any of our current directors or officers or a trustee or fiduciary holding our securities, becomes the beneficial owner of more than 50% of the combined voting power of our outstanding securities

● An acquisition, sale, merger, or other transaction that results in a change in ownership of more than 50% of the combined voting power of our stock

● A change in the majority of our Board of Directors over a two-year period that is not approved by at least two-thirds of the directors then in office who were directors at the beginning of the period

● Any event requiring a reporting of a CIC pursuant to the regulations under SEC Form 8-K

● Execution of an agreement with us, which if consummated, would result in any of the above events

*Definition of "Cause."* Cause generally includes:

● Acts of dishonesty

● Repeated failure to perform duties which are demonstrably and deliberate and not remedied after receipt of notice

● Conviction of a felony

● Intentional breach of our COC, which is materially and demonstrably injurious to the Company

COMPENSATION TABLES

*Definition of "Constructive Termination."* A "Constructive Termination" generally includes any of the following actions taken by the Company without the executive's written consent following a CIC:

● Significantly reducing or diminishing the nature or scope of the executive's authority or duties including reporting to someone whose scope of authority is diminished

● Materially reducing the executive's annual salary or incentive compensation opportunities

● Failure of a successor to assume the agreement

● Changing the executive's principal office location by more than 50 miles

● Failing to provide substantially similar fringe benefits, or substitute benefits that were substantially similar to the benefits provided as of the date of the agreement

● Failing to obtain a satisfactory agreement from any successor to us to assume and agree to perform the obligations under the agreement

**Estimated Benefits on Termination Following a Change-in-Control** 

The following table shows potential payments to our NEOs if their employment terminates following a CIC under existing contracts, agreements, plans, or arrangements. The amounts assume a December 31, 2022 termination date and use the closing price of our common stock as of that date, $235.35. All the values in the table are in U.S. Dollars. Based on current assumptions, modifications to payments are not needed related to golden parachute excise tax.

&nbsp;&nbsp;&nbsp;&nbsp;(1) For Mr. Green, the aggregate severance pay amount represents two times the sum of the executive's (a) highest annual base salary in effect during his year of termination and (b) the average of his bonus payout in the three years preceding the CIC (the "Severance Basis"). For all other NEOs, the bonus component of the Severance Basis is equal to their target bonus in the year of termination, and the aggregate severance pay is two times the Severance Basis.

&nbsp;&nbsp;&nbsp;&nbsp;(2) This amount represents the payout of all outstanding PSU awards on a change-in-control at the target payout.

&nbsp;&nbsp;&nbsp;&nbsp;(3) This amount represents the value of all unvested restricted awards, which would become vested on a change-in-control (whether or not the awards were deferred).

&nbsp;&nbsp;&nbsp;&nbsp;(4) This amount is the intrinsic value, which is equal to the fair market value of a share of stock on December 31, 2022, minus the per-share exercise price of all unvested stock options for each executive multiplied by the number of unvested options as of December 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(5) This amount represents the vesting of any unvested benefits and matching contributions under our 401(k) plan and the Employee Deferred Compensation Plan as of December 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(6) This amount represents the employer portion of the premiums for medical, dental and life insurance coverage for 24 months.

&nbsp;&nbsp;&nbsp;&nbsp;(7) This amount estimates the cost of providing outplacement assistance.

#### CEO Pay Ratio
Applicable SEC rules require the disclosure of our median team member's pay and the ratio of that pay to our CEO's pay. Our CEO pay ratio and the underlying compensation and team member count data are reasonable estimates calculated consistent with applicable SEC guidance governing the use of estimates, adjustments and statistical sampling permitted by the SEC.

The median team member's identity was determined as of December 2020, and we used "base pay" as our compensation definition, which we then calculated as annual base pay based on a reasonable estimate of hours worked during 2020 for hourly workers, and upon salary levels for the remaining team members. We did not utilize cost-of-living adjustments. We annualized pay for those who commenced work during 2020. We used a valid statistical sampling methodology to identify the base pay for the median worker. In addition, in selecting the median worker, as permitted by applicable SEC regulations, we used our global employment roster as of November 30, 2020, but excluded all team members in the following countries (with the number of team members excluded in parentheses): Australia (3), Argentina (6), Italy (10), Spain (5), and Serbia (374). As of November 30, 2020, total number of team members was 9,175, with U.S. team members totaling 4,061 and foreign team members totaling 5,114. As of December 31, 2022, the total number of team members was 10,769, with U.S. team members totaling 4,766 and foreign team members totaling 6,003.

Mr. Green's 2022 pay, as indicated in our 2022 Summary Compensation Table was $7,785,232 and our median team member's pay calculated in the same manner was $60,629. The ratio of Mr. Green's pay to our median worker's pay as determined under applicable SEC rules, therefore, is: 128:1.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Amounts shown for Compensation "Actually Paid" are computed in accordance with Item 402(v) and do not reflect the actual amount of compensation earned by or paid to the NEOs during the applicable year. These amounts reflect total compensation as reported in the Summary Compensation Table with certain adjustments as described in footnote (3) below.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Compensation "Actually Paid" reflects the exclusions and inclusions of equity awards for the PEO and the other NEOs as set forth below and calculated in accordance with FASB ASC Topic 718. The valuation methodologies and assumptions used to calculate Compensation "Actually Paid" are based on our grant date fair value of these awards as disclosed in the company's audited financial statements for the years reflected in the table below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) For the PEO and other NEOs, for each covered year, service cost and prior service cost of pension benefits equals $0 , fair value of awards that are granted and vest in the same covered fiscal year equals $0 , and fair value of awards granted in prior years that are determined to fail to meet the applicable vesting conditions during the covered fiscal year equals $0 .

Equity Valuations: Stock option grant date fair values are calculated based on the Black-Scholes option pricing model as of date of grant. Adjustments have been made using stock option fair values as of each measurement date using the stock price as of the measurement date and updated assumptions (i.e., term, volatility, dividend yield, risk free rates) as of the measurement date. Performance-based restricted share unit grant date fair values are calculated using the stock price as of date of grant assuming target performance. Adjustments have been made using the stock price and performance accrual modifier as of year-end and as of the date of vest. Time-based restricted share unit grant date fair values are calculated using the stock price as of date of grant. Adjustments have been made using the stock price as of year-end and as of each vesting date in accordance with Item 402(v). The aggregate change in actuarial present value of accumulated benefit under pension plans reflects the amount reported for the applicable year in the SCT.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Pursuant to Item 402(v), we determined West's revenue to be the most important financial performance measure used to link Company performance to Compensation "Actually Paid" to our PEO and other NEOs, and this is designated as our Company-Selected Measure for 2022. This performance measure may not have been the most important financial performance measure for years 2021 and 2020, and we may determine a different financial performance measure to be the most important such measure in future years.

**Relationship Between Pay and Performance**

A full description of the selection of our criteria, additional detail regarding the elements of our executive compensation design and the linkage of pay-and-performance reviewed by our Compensation Committee is discussed in our Compensation Discussion and Analysis above. We believe our analysis demonstrates our pay-for-performance philosophy, which creates long-term value and benefits our shareholders. Item 402(v) relies heavily on stock pricing on particular dates and, as those values change considerably, could lead to different results depending on these fluctuations. As required by Item 402(v), the following charts set forth the relationship between Compensation "Actually Paid" to our PEO, the average of Compensation "Actually Paid" to our other NEOs, and the Company's cumulative TSR, S&P 500 Health Care Index, Net Income, and Revenue over the three-year period from 2020 through 2022, each as set forth in the

| PROPOSAL 2 |

---

&nbsp;&nbsp;<br>Proposal 2 — Advisory Vote to Approve Named Executive Officer Compensation<br>

At our 2022 Annual Meeting, our advisory vote on executive pay was approved by 93.2% of the votes cast. The Board of Directors and its Compensation Committee believed this to be a confirmation that our executive pay accurately and appropriately rewards performance. Previously, a majority of our shareholders approved holding an advisory vote on executive compensation annually. Therefore, we are seeking an advisory vote approving executive compensation again this year.

As described more fully in the "Compensation Discussion and Analysis" section, our executive compensation program is designed to provide competitive executive pay opportunities tied to our short-term and long-term success and attract, motivate and retain the type of executive leadership that will help us achieve our strategic goals. The Compensation Committee continually reviews the compensation programs for our NEOs to ensure they achieve the desired goals of aligning our executive compensation structure with our shareholders' interests and current market practices.

This vote is advisory and not binding on the Company, the Board and the Compensation Committee. However, the Board and the Compensation Committee are interested in the opinions expressed by our shareholders on this proposal and will consider the outcome of the vote when making future compensation decisions for the NEOs. We encourage shareholders to review the Compensation Discussion and Analysis section of this Proxy Statement, for details regarding our executive compensation program.

Accordingly, the following resolution will be submitted for a shareholder vote at the 2023 Annual Meeting:

"RESOLVED, That the shareholders of West Pharmaceutical Services, Inc. (the 'Company') approve, on an advisory basis, the compensation of the Company's Named Executive Officers, as disclosed in this Proxy Statement pursuant to Item 402 of Securities and Exchange Commission Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative disclosures."

<br>**The Board unanimously recommends a vote FOR the approval, on an advisory basis, of the Company's**<br>**Named Executive Officer compensation, as stated in the above resolution.**<br>

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services

Our Audit Committee has responsibility for appointing, setting compensation and overseeing the work of the Company's independent registered public accounting firm. The Audit Committee has delegated authority to Mr. Birkett and Chad Winters, our Chief Accounting Officer, with the Audit Committee Chair's approval, to engage PwC to perform services of less than $10,000 so long as the provision of those services would not impact the independence of PwC. Additionally, the Committee requires that Mr. Birkett and Mr. Winters report at each meeting regarding the nature and amount of any such services that we have retained. This revised process preserves independence with our registered public accounting firm, while permitting Management the flexibility to use that firm for non-audit fees and services. Subject to a de minimis exception for non-audit services set forth in applicable rules of the SEC, all other services performed by the independent registered public accounting firm and related fees are submitted to the Audit Committee in advance for its approval. Those services must fall within one of the four categories discussed below.

***Audit Fees*** include fees for audit work performed on the financial statements and internal control over financial reporting, and work that generally only the independent registered public accounting firm can reasonably be expected to provide, including statutory audits or financial audits for our subsidiaries or affiliates; services associated with SEC registration statements; periodic reports and other documents filed with the SEC or other documents issued in connection with securities offerings (e.g., comfort letters, consents); and assistance in responding to SEC comment letters.

***Audit-Related Fees*** are fees for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements and are traditionally performed by the independent registered public accounting firm, including due diligence related to potential business acquisitions/divestitures, financial statement audits of employee benefit plans and special procedures required to meet certain regulatory requirements.

***Tax Fees*** include fees for all services, except those specifically related to the audit of the financial statements, which are performed by the independent registered public accounting firm's tax personnel and may include tax advice, tax analysis and compliance, and review of income and other tax returns.

***All Other Fees*** are fees for those services not captured in any of the above three categories. The percentage of fees in this category that were approved by the Audit Committee under the de minimis exception was less than 1% of the total fees for 2022.

Audit Committee Report

The Audit Committee reviewed the Company's financial-reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process, including the system of internal controls. PwC, the Company's independent registered public accounting firm, is responsible for expressing its opinion on the conformity of the Company's audited financial statements with generally accepted accounting principles and on the effectiveness of the Company's internal control over financial reporting.

The Audit Committee has reviewed and discussed with Management and PwC the audited financial statements for the year ended December 31, 2022, Management's assessment of the effectiveness of the Company's internal control over financial reporting and PwC's evaluation of the Company's internal control over financial reporting.

The Audit Committee has discussed with PwC the matters that are required to be discussed pursuant to the Public Company Accounting Oversight Board's Auditing Standard No. 131—Communications with Audit Committees. PwC has provided to the Committee the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding PwC's communications with the Audit Committee concerning independence and the Committee has discussed with PwC that firm's independence from the Company.

The Audit Committee also considered whether the independent registered public accounting firm's provision of non-audit services to the Company is compatible with the auditor's independence. The Audit Committee has concluded that the independent registered public accounting firm is independent from the Company and its Management. Based on the considerations and discussions referred to above, the current members of the Audit Committee recommended to the Board that the audited financial statements for the year ended December 31, 2022 be included in the Company's 2022 Annual Report on Form 10K.

&nbsp;&nbsp;<br>Proposal 3 — Ratification of the Appointment of PricewaterhouseCoopers LLP as Our Independent Registered Public Accounting Firm<br>

The Audit Committee is responsible for the appointment, compensation, retention, evaluation and oversight of the Company's independent registered public accounting firm. This Committee annually evaluates the independent registered public accounting firm's qualifications, performance and independence and assesses whether to continue to retain the firm or select a different firm.

As part of this review, the Audit Committee reviews PwC's capabilities and costs, including consideration of non-audit fees and services. Based on this review, the Audit Committee has determined that PwC has performed well, in a cost-effective manner, has a longstanding institutional memory, acts independently of Management and provides critical input to the Audit Committee. The Committee also considers the impact of changing auditors when assessing whether to retain the current auditor. Therefore, the Audit Committee has appointed PwC as our independent registered public accounting firm for 2023. Although shareholder approval for this appointment is not required, the Audit Committee and our Board are submitting the selection of PwC for ratification to obtain the views of shareholders and as a matter of good corporate governance. If the appointment is not ratified, the Audit Committee will reconsider whether or not to retain PwC. Representatives of PwC will be present at the 2023 Annual Meeting to answer questions and will have the opportunity to make a statement if they desire.

<br>**The Board unanimously recommends a vote FOR the ratification of the appointment of PricewaterhouseCoopers LLP as ourindependent registered public accounting firm for 2023.**<br>

PROPOSAL 4

&nbsp;&nbsp;<br>Proposal 4 — Advisory Vote on the Frequency of an Advisory Vote on Executive Compensation<br>

Our shareholders are permitted by Federal law to indicate how frequently we should seek an advisory vote on the compensation of our NEOs (as described in Proposal 2). By voting on this Proposal 4, shareholders may indicate whether they would prefer an advisory vote on NEO compensation once every one, two or three years.

The frequency of the executive compensation vote is advisory only and is non-binding; however, the Compensation Committee and the Board value the opinions of the shareholders and will consider the outcome of the vote when determining the frequency of the shareholder vote on executive compensation.

After careful consideration of this Proposal, our Board has determined that an annual advisory shareholder vote on executive compensation is the most appropriate for us and, therefore, our Board recommends that you vote for a one-year interval for the advisory vote on executive compensation.

In making its recommendation, our Board considered that an annual advisory vote on executive compensation will allow our shareholders to provide us with their direct input on our compensation philosophy, policies and practices, as disclosed in this Proxy Statement on the most frequent basis. Additionally, an annual advisory vote on executive compensation is consistent with our policy of seeking input from, and engaging in discussions with, our shareholders on corporate governance matters and our executive compensation philosophy, policies and practices.

You may cast your vote on your preferred voting frequency by choosing the option of one year, two years, three years or abstain from voting.

The option of one year, two years or three years that receives the highest number of votes cast by shareholders will be the frequency for the advisory vote on executive compensation that has been selected by the shareholders. However, because this vote is advisory only and not binding on the Board or us, the Board may decide that it is in the best interests of our shareholders and us to hold an advisory vote on executive compensation more or less frequently than the option approved by our shareholders.

**The Board unanimously recommends that an advisory vote on executive compensation be held every ONE year.**<br>

&nbsp;&nbsp;<br>Proposal 5 — Shareholder proposal entitled "Fair Elections"<br>

We received the following shareholder proposal (the "Proposal") from Myra K. Young (the "Proponent"), 9295 Yorkship Court, Elk Grove, California 95758, the beneficial owner of 40 shares of our common stock. The Proponent has requested that we include the Proposal and supporting statement (the "Supporting Statement") in this Proxy Statement and, if properly presented, the Proposal will be voted on at the annual meeting. This Proposal and Supporting Statement, as submitted by Ms. Young, are quoted verbatim in italics below. We and the Board disclaim any responsibility for the content of the Proposal and the Supporting Statement.

The Board opposes adoption of the Proposal and asks shareholders to review the Board's response, which follows the Proponent's Proposal.

**NOTE: The graphic above was submitted as part of the shareholder's proposal.**

**Proposal 5 - Fair Elections**

***Resolved***

*Myra K. Young and other shareholders request that directors of West Pharmaceutical Services Inc. ("Company") amend its bylaws to include the following language:*

*Shareholder approval is required for any advance notice bylaw amendments that:*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*1.* *require the nomination of candidates more than 90 days before the annual meeting,* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*2.* *impose new disclosure requirements for director nominees, including disclosures related to past and future plans, or* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*3.* *require nominating shareholders to disclose limited partners or business associates, except to the extent such investors own more than 5% of the Company's shares.* 

***Supporting Statement***

*Under SEC Rule 14a-19, the universal proxy card must include all director nominees presented by management and shareholders for election.*<sup>[1](#footnote-2)</sup> *Although the Rule implies each side's nominees must be grouped together and clearly identified as such, in a fair and impartial manner, most rules for director elections are set in company bylaws.*

*For Rule 14a-19 to be implemented equitably, boards must not undertake bylaw amendments that deter legitimate efforts by shareholders to submit nominees. The bylaw amendments set forth in the proposed resolution would presumptively deter legitimate use of Rule 14a-19 by deterring legitimate efforts by shareholders to seek board representation through a proxy contest.*

PROPOSAL 5

*The power to amend bylaws is shared by directors and shareholders. Although directors have the power to adopt bylaw amendments, shareholders have the power to check that authority by repealing board-adopted bylaws. Directors should not amend the bylaws in ways that inequitably restrict shareholders' right to nominate directors. This resolution simply asks the board to commit not to amend the bylaws to deter legitimate efforts to seek board representation, without submitting such amendments to shareholders. We urge the Board not to further amend its advance notice bylaws until shareholders have at least voted on this proposal.*

*Bloomberg's Matt Levine speculates bylaws might require disclosure submissions "on paper woven from unicorns' manes,"*<sup>[2](#footnote-3)</sup> *with requirements waived for the board's nominees. While Mr. Levine depicts humorous and exaggerated possibilities, some companies are adopting amendments clearly designed to discourage fair elections.*

*Directors of at least one company (Masimo Corp.) recently adopted bylaw amendments that could deter legitimate efforts by shareholders to seek board representation through a proxy contest. Masimo's advance notice bylaws "resemble the 'nuclear option' and offers a case study in how rational governance devices can become unduly weaponized, writes Lawrence Cunningham.*<sup>[3](#footnote-4)</sup> *Directors of other companies are considering similar proposals.*

*To ensure shareholders can vote on any proposal that would impose inequitable restrictions, we urge a vote FOR Fair Elections.*

***To Enhance Shareholder Value, Vote FOR***

***Fair Elections - Proposal 5***

#### Board of Directors Statement in Opposition
Our Board has carefully reviewed and considered this Proposal and recommends a vote AGAINST it because it is:

● An infringement on the Board's crucial governance role

● Inconsistent with the intentions of the Pennsylvania law

● Unnecessary and not in the best interests of shareholders, and

● Imprecise, which makes it extremely difficult to implement in a way consistent with shareholder expectations.

The Board remains committed to strong corporate governance practices and responsiveness to shareholders through regular dialogue. The Board also believes in maintaining policies and practices that serve the best interests of all shareholders and regularly evaluates these policies and practices.

#### Infringes on Board's Governance Role
If approved, the Proposal would restrict our Board's central role in establishing West's corporate governance practices and limit the ability of our Board to exercise its fiduciary duties to act in the best interest of West and its constituents.

Our Board is responsible for managing the business and affairs of the corporation and unlike shareholders, each of our directors owe fiduciary duties to the corporation that require them to take all actions that they reasonably determine are in West's best interests and the best interests of West's stakeholders. The Proposal asks the Board to adopt a new bylaw that would require any future bylaw amendments regarding certain advance notice to be approved by a vote of our shareholders under all circumstances, imposing improper and overbroad limitations on the Board's ability to manage our business and affairs. This potentially prevents our directors from being able to properly and timely discharge their fiduciary duties when considering a wide range of potential corporate action.

Board-adopted corporate bylaws protect corporations against potential threats to their long-term strategy and help to create and defend long-term shareholder value by allowing directors and management to focus on the long-term health and growth of the corporation rather than short-term financial performance. The Proposal would put the Board and West at a substantial disadvantage as compared to other public companies and would result in far less transparency. For example, the Proposal likely would limit the Board's ability to properly consider potential Board nominees by effectively imposing limitations on the Board's ability to properly interview and assess the candidacy and appropriateness of potential

---

Board candidates to be voted on by the shareholders. We believe that the current construct of our bylaws and our corporate governance practices, which are consistent with that of many other public companies, are equitable, fair, reasonable and appropriately aligned with our long-term shareholders' interests.

#### State Law Concerns
The Proposal also fails to consider certain critical aspects of Pennsylvania law. This is an emerging area of law which appears to have been generated by the SEC's recently adopted universal proxy card rules as noted above by the Proponent. Therefore, bylaw restrictions like those of the Proposal do not appear to have been directly addressed by Pennsylvania courts yet. However, in many states, including Delaware, a shareholder proposal that attempts to eliminate or modify the Board's ability to amend the bylaws violates applicable state law. Delaware has developed one of the most respected bodies of corporate law and where an issue is not addressed by state statute, other courts, such as those in Pennsylvania, will often look to Delaware to see how an issue is addressed. In this case, a substantially similar shareholder proposal to the Proposal was submitted to a Delaware corporation and recently withdrawn, likely because it conflicts with Delaware laws that are similar to Pennsylvania's laws. Pennsylvania, like Delaware, expressly recognizes the central role of the board of directors in establishing the corporate governance practices of a corporation with publicly-traded securities and protecting long-term shareholder value.

Moreover, Pennsylvania statutes include various default rules that restrict or eliminate governance rights that are available to corporate shareholders in other states. For example, shareholders in a publicly-traded Pennsylvania corporation are generally prohibited from calling special meetings of shareholders, acting by less than unanimous written consent or proposing amendments to the articles of incorporation. Importantly, shareholders of a Pennsylvania corporation like West are prohibited from adopting a bylaw that would vary the authority or powers of the board without their approval, expressly codifying the board's vital role in establishing corporate governance practices. The Pennsylvania legislature has also indicated that these limitations are "considered more appropriate for publicly-traded corporations." The Proposal attempts to circumvent this restriction by instead making a "request" that the Board amend the Bylaws. As mentioned above, we believe the Proposal directly conflicts with the unconditional right of our Board to adopt future bylaw amendments that the Board determines are in the best interest of shareholders.

#### Necessity of Amendment and Inconsistent with Shareholders' Interests
We continually evaluate developments in corporate governance and implement appropriate changes to our corporate governance practices that our Board believes are in the best interests of West and its stakeholders. For example, when we voluntarily implemented our advance notice bylaw provisions in 2021, the Board considered, among other things, benchmarking data of S&P 500 companies and our comparable peer companies and then current best practices for advance notice bylaw provisions, which balance all stakeholder interests. Additionally, this is consistent with Pennsylvania law, which expressly provides that corporate bylaws may include a "fair and reasonable procedure for the nomination of candidates for election as directors" and our bylaws permit our Board to adopt such bylaws without shareholder approval.

#### Imprecision of the Proposal Makes Implementation Unclear
The lack of precision in the Proposal makes it difficult to implement and makes compliance unclear. Additionally, the SEC has indicated a proposal may be materially misleading if it is vague and indefinite when interpretation of the meaning and application of terms and conditions in the Proposal would have to be made without guidance from the text, Proponent or voting shareholders.

If approved, the language of the Proposal would require shareholder approval for any amendment to our advance notice bylaw(s) that, among other things, "***impose new disclosure requirements for director nominees, including disclosures related to past and future plans***, . . ." (emphasis added). We believe the phrase "past and future plans" is both vague and indefinite, as the meaning of past and future plans could be subject to materially different interpretations by us and shareholders voting on the Proposal, and it is unclear what that phrase modifies. For example, the required disclosure could be interpreted to relate to a director nominee's "past and future plans" regarding our business operations, which we believe is absolutely critical to evaluate any director nominee. However, when read in conjunction with requirement three of the Proposal's resolution (i.e., "require nominating shareholders to disclose limited partners to disclose limited partners or business associates, except to the extent such investors own more than 5% of the Company's shares"), "past and future plans" could be interpreted to relate to a director nominee's plans regarding West's securities. If the Proposal is approved, these differing interpretations, among others, could lead to uncertainty as to when we must

[**Table of Contents**](#TOC)

![Graphic](wst-20230425xdef14a_a002.jpg)

PROPOSAL 5

seek shareholder approval of a future amendment to the bylaws. This uncertainty would place West at a distinct disadvantage when faced with, among other things, a potential takeover attempt.

We believe that the term "past and future plans" is so vague and indefinite as to make the Proposal itself materially misleading and these potentially divergent interpretations of the vague language included in the Proposal could result in actions taken by us which do not align with the shareholders' expectations. Understanding this term is critical because, if the Proposal is approved and the requested bylaw amendment adopted by our Board, the exact words contained in the Proposal would be included in our Bylaws and would create significant legal uncertainty as to the meaning and application of the words "past and future plans."

Despite these issues, the language of the Proposal leaves our Board with no discretion in its implementation because it requests specific language be added to our Bylaws. The Proposal explicitly requests that the Bylaws "include the following language," and the Board does not have the ability to effectively alter the language provided in the Proposal. Further, due to the lack of any clarifying language in the Proponent's supporting statement, if the Board were to take it upon itself to clarify the meaning of "past and future plans," the Board would be at risk of materially altering the intent of the Proposal and diverging from what was contemplated by the Proponent and/or voting shareholders.

#### Summary
The Board believes that the implementation of the Proposal is not in the best interest of shareholders or West, is unnecessary given our strong corporate governance practices and policies and fails to consider certain aspects of Pennsylvania law. Further, as discussed above, because the Proposal includes a material term that is so inherently vague or indefinite that the proposal itself is materially misleading and neither the shareholders voting on it, nor us in implementing it (if adopted), would be able to determine with any reasonable certainty exactly what actions or measures the proposal requires.

In conclusion, the Board recommends that you vote AGAINST Proposal 5 because it: (1) infringes on the Board's governance role; (2) is inconsistent with the intention of Pennsylvania law; (3) is unnecessary and not in the best interest of the shareholders; and (4) is imprecise to the point of making it difficult to implement.

**The Board unanimously recommends a vote AGAINST the shareholder proposal entitled "Fair Elections."**<br>

VOTING AND OTHER INFORMATION

*Plan Participants.* Any shares you may hold in the West Pharmaceutical Services, Inc. 401(k) Plan or the West Contract Manufacturing Savings and Retirement Plan have been added to your other holdings on your proxy card.

Your completed proxy card serves as voting instructions to the trustee of those plans. You may direct the trustee how to vote your plan shares by submitting your proxy vote for those shares, along with the rest of your shares, by Internet, phone or mail, all as described on the enclosed proxy card.

If you do not instruct the trustee how to vote, your plan shares will be voted by the trustee in the same proportion that it votes shares in other plan accounts for which it received timely voting instructions.

Broker Voting and Votes Required

For holders in "Street Name," the Notice would have been made available to you by your broker, bank or other holder of record who is considered the shareholder of record of those shares. As the beneficial owner, you may direct your broker, bank or other holder of record on how to vote your shares by using the proxy card included in the materials made available to you or by following their instructions for voting on the Internet. A broker non-vote occurs when a broker or other nominee that holds shares for another does not vote on an item because the nominee does not have discretionary voting authority for that item and has not received instructions from the owner of the shares. Although there is no controlling precedent under Pennsylvania law regarding the treatment of broker non-votes in certain circumstances, we intend to apply the principles outlined in the table below:

The proposal should be sent to the attention of the Corporate Secretary in writing and should be mailed by certified mail, return receipt requested to: West Pharmaceutical Services, Inc., 530 Herman O. West Drive, Exton, PA 19341.

Our Bylaws set forth procedures that a shareholder must follow to nominate persons for election as directors or to introduce an item of business at an Annual Meeting of shareholders without seeking access to our proxy materials. Nominations for director nominees or an item of business to be conducted without seeking access to our proxy materials must be submitted in writing to the Corporate Secretary of the Company at West Pharmaceutical Services, Inc., 530 Herman O.
