#### Dear AmerisourceBergen shareholders:
On behalf of the Board of Directors, I want to thank you for your continued investment in AmerisourceBergen.

During fiscal 2022, the AmerisourceBergen team delivered exceptional execution and performance, demonstrating the Company's continued leadership as a global healthcare company. Throughout the year, AmerisourceBergen fulfilled its purpose to create healthier futures by supporting the response to the COVID-19 pandemic, ensuring the delivery of crucial medications and services around the world, and advancing pharmaceutical innovation and access. These accomplishments were achieved in a complex operating environment marked by inflationary pressures and macroeconomic challenges and are a testament to the dedication of 43,000 global team members. As a result of their efforts, AmerisourceBergen successfully fortified its foundation for further growth in fiscal 2023.

A key strategic priority for the Board and Executive Management Committee in fiscal 2022 was the successful integration of Alliance Healthcare, which AmerisourceBergen acquired in June 2021. To this end, the Merger Integration Committee, which is comprised solely of independent directors, provided guidance to the AmerisourceBergen management team and assisted the full Board with oversight of management's integration of Alliance Healthcare. Alliance Healthcare expanded AmerisourceBergen's global capabilities, and the Board is confident that the recent acquisition of PharmaLex will further enhance AmerisourceBergen's portfolio of solutions and strengthen its ability to support customers.

As part of our efforts to oversee the Company's long-term strategy, the Board remained focused on supporting AmerisourceBergen's ESG initiatives. Members of the Board had the opportunity to participate in discussions with several of our largest shareholders through our ongoing shareholder engagement program and were pleased to receive positive feedback on AmerisourceBergen's ESG progress. One key topic of discussion was the Compensation Committee's incorporation of a new ESG metric within the executive compensation program for 2023. Shareholders appreciated the design of the metric, which helps to reinforce AmerisourceBergen's ESG priorities. They also expressed support for the Company's new integrated talent framework and its commitment to reducing greenhouse gas emissions through the adoption of Science-Based Targets.

We also made Board succession planning a priority and recently welcomed Dr. Lorence Kim and Dr. Redonda Miller as new independent directors. Lorence and Redonda are well positioned, including through their considerable healthcare expertise, to help the Board oversee AmerisourceBergen's efforts to drive growth through innovation.

As part of our succession strategy, Michael Long and I will not be standing for re-election at this annual meeting. Mike has been a valued member of the Board, and we are incredibly grateful for his many contributions. For me, it has been an honor to serve as a member of the Board and to serve as the Lead Independent Director for the past several years. I leave knowing that the role of Lead Independent Director will be in very capable hands. Mark Durcan has been elected by the independent directors to succeed me as Lead Independent Director following the annual meeting. Mark's experience as a public company CEO, service on other public company boards, and substantial experience in strategic planning, global markets and technological innovation make him well-equipped to serve in this important role.

On behalf of the entire Board, we are grateful for your support of the Board and AmerisourceBergen. The Board remains committed to ongoing dialogue with shareholders and values your input as we continue to evolve our practices and policies. Along with our shareholder engagement efforts, your vote is an important source of feedback. We encourage you to read the information in the proxy statement and the annual report in its entirety.

We respectfully request your support for our voting recommendations at the 2023 Annual Meeting of Shareholders, to be held virtually on Thursday, March 9, 2023, at 3:00 p.m.

#### Positive impact on global health
Throughout the COVID-19 pandemic, AmerisourceBergen has been guided by its purpose of being united in its responsibility to create healthier futures. We work to maintain a safe and secure pharmaceutical supply chain to ensure the health of the people and communities we serve and to protect the wellbeing of our team members in the process. Given AmerisourceBergen's vital role in the supply chain, in addition to focusing on our normal supplier processes, our teams worked throughout the COVID-19 pandemic to ensure that critical medications were allocated to our customers fairly to facilitate optimal patient access. We continue to utilize a peer-to-peer safety program, and regularly convene our company leaders to review and evaluate safety data and issue operational excellence scorecards. We also continue to follow clinical and regulatory guidance as it relates to COVID-19.

Since the pandemic, we have further evolved our capabilities and response measures to increase our agility and resiliency in the face of the next crisis. We are well positioned to tackle emerging healthcare challenges, in particular those that unfairly affect vulnerable populations, due to our global distribution model and strong partnerships with international governments, manufacturers, and non-profits throughout local communities. In 2022, the U.S. Department of Health and Human Services awarded AmerisourceBergen a contract for the distribution of mpox vaccines across the United States. We are supporting the Strategic National Stockpile to quickly deliver vaccines and treatment to communities living with the greatest risk of infection.

AmerisourceBergen and Alliance Healthcare have committed support to a campaign to tackle Anti-Microbial Resistance ("AMR"), another significant global public health issue, by using commercial, philanthropic, and thought leadership channels. In conjunction with upstream and downstream partners, we are responding to the threat of AMR by championing the safe and responsible use of anti-microbial treatments for human and animal health.

## Item 1 — Election of directors

#### Annual election of directors
Directors are elected annually. Any nominee who is elected to serve as a director at our 2023 Annual Meeting of Shareholders will be elected to serve a term of one year and is expected to hold office until the 2024 Annual Meeting of Shareholders and until their successors are elected and qualified. Similarly, any director who is appointed to fill a vacancy on the Board will serve until the next annual meeting of shareholders after his or her appointment and until his or her successor is elected and qualified.

Each nominee for director has consented to his or her nomination and, so far as the Board and management are aware, intends to serve a full term as a director if elected. However, if any of the nominees should become unavailable or unable to stand for election prior to the election, the shares represented by proxies may be voted for the election of substitute nominees selected by the Board.

#### Board size and director nominees
The Board currently has 12 members, 10 of whom are standing for re-election at the 2023 Annual Meeting of Shareholders. As of the 2023 Annual Meeting of Shareholders, the size of the Board will be reduced from 12 members to 10. As previously announced, Jane E. Henney, M.D. and Michael Long are not standing for re-election at the 2023 Annual Meeting of Shareholders. We acknowledge and thank each of Dr. Henney and Mr. Long for their service.

The director nominees are listed below. Biographical information about our director nominees can be found on pages 14-18.

#### Walgreens Boots Alliance's designated director nominee
Pursuant to the Amended and Restated Shareholders Agreement between AmerisourceBergen and Walgreens Boots Alliance, Inc. (as successor in interest to Walgreen Co. and Alliance Boots GmbH), Walgreens Boots Alliance has the right to designate a director to our Board once Walgreens Boots Alliance and certain of its subsidiaries collectively own five percent or more of our Common Stock. On May 1, 2014, Walgreens Boots Alliance notified us that it had acquired at least five percent of our Common Stock. Ms. Barra, Chief Operating Officer, International of Walgreens Boots Alliance, has been designated by Walgreens Boots Alliance to serve on our Board. She was appointed to the Board on January 16, 2015 and is a current nominee for election as director. In addition, upon the acquisition in full by Walgreens Boots Alliance and its subsidiaries of 19,859,795 shares of our Common Stock in the open market, Walgreens Boots Alliance will be entitled to designate a second director to the Board. For so long as Walgreens Boots Alliance has a right to designate a director to the Board, subject to certain exceptions, including matters related to acquisition proposals, Walgreens Boots Alliance and its subsidiaries will be obligated to vote their shares in accordance with our Board's recommendations on all matters submitted to a vote of our shareholders.

#### Identification and evaluation of director nominees and overboarding policy
Our Governance, Sustainability & Corporate Responsibility Committee seeks director nominees who possess qualifications, experience, attributes and skills that will enable them to contribute meaningfully to the leadership of our Board and to effectively guide and supervise management in driving AmerisourceBergen's growth and financial and operational performance. Each director nominee should:

• possess the highest personal and professional ethics, integrity and values;

• be committed to representing the long-term interests of our shareholders; and

• have an inquisitive and objective perspective, practical wisdom and mature judgment.

Each director nominee should also have sufficient time to effectively carry out his or her duties as a director. Pursuant to our corporate governance principles, our Chief Executive Officer may serve on no more than one other public company board and our other director nominees may serve on no more than three other public company boards.

In addition, our Governance, Sustainability & Corporate Responsibility Committee has identified the following expertise, experience, attributes and skills that are particularly relevant to AmerisourceBergen:

• Corporate governance • Distribution and logistics • Executive leadership • Financial literacy • Global markets • Healthcare • Information technology (including cybersecurity) • Regulatory • Risk oversight • Sustainability and corporate responsibility • Talent management and executive compensation

We seek individuals with diverse backgrounds, skills and expertise to serve on our Board. We believe that diversity is essential to encourage fresh perspectives, enrich the Board's deliberations and avoid the dominance of a particular individual or group over the Board's decisions. In accordance with our corporate governance principles and the Governance, Sustainability & Corporate Responsibility Committee charter, the Governance, Sustainability & Corporate Responsibility Committee has formalized its diversity focus to include, and have any search firm that it engages include, women and ethnically and racially diverse candidates in the pool from which the committee selects new director candidates. The Governance, Sustainability & Corporate Responsibility Committee evaluates all potential director nominees using the same criteria, regardless of the source of the nominee. Accordingly, all potential director nominees, including shareholder nominees, are assessed using the criteria outlined above. The Governance, Sustainability & Corporate Responsibility Committee may consider and evaluate director nominees identified by our shareholders as described below in the section titled "Shareholder recommendations for director nominees."

Below are each director nominee's biography and an assessment of the above-mentioned expertise, experience, attributes and skills that each director nominee possesses that led to the conclusion that the individual should serve as a director on our Board.

## Non-employee director compensation at 2022 fiscal year end
Our director compensation program is designed to attract and retain qualified non-employee directors. Our program aligns director compensation with the compensation of our peers (our peer companies are identified on page 50). Our Governance, Sustainability & Corporate Responsibility Committee reviews non-employee director compensation regularly to confirm that it appropriately addresses time, effort, expertise, and accountability required of active board membership.

The following table summarizes the total compensation earned by directors who were not employees of AmerisourceBergen during fiscal 2022. Ms. Barra waived her right to receive compensation as a non-employee director. Directors who are employees of AmerisourceBergen receive no compensation for their service as directors or as members of Board committees.

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In May 2022, the annual equity awards were increased to $200,000 for non-employee directors, and to $250,000 for the Lead Independent Director. As discussed in greater detail below, the annual equity awards for fiscal 2022 were granted prior to the approved increases and therefore were equal to $175,000 and $200,000 for non-employee directors and the Lead Independent Director, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In May 2022, the committee chair fees for the Finance Committee and the Governance, Sustainability & Corporate Responsibility Committee were increased from $15,000 to $20,000.

#### Annual retainers
A director may elect to have the annual retainer paid in cash, Common Stock or restricted stock units, or credited to a deferred compensation account. Payment of annual retainers in cash are made in equal quarterly installments.

#### Annual equity awards
On March 10, 2022, each of the non-employee directors (other than Ms. Barra, who waived compensation) received an annual grant of restricted stock units. The vesting period for these awards is one year from the date of grant, subject to continued service on the Board or following retirement by a director who, after reaching age 55, has an age plus years of continuous service with the Company that equals at least 65. These grants were made under the AmerisourceBergen Corporation 2022 Omnibus Incentive Plan (the "Omnibus Incentive Plan"). A director may defer settlement of shares payable with respect to restricted stock units as described below.

#### Deferral and other arrangements
Directors have the option to defer all or any part of the annual retainer and to credit the deferred amount to an account under the AmerisourceBergen Corporation Deferred Compensation Plan (the "Deferred Compensation Plan"). Payment of deferred amounts will be made or begin on the first day of the month after the non-employee director ceases to serve as a director. A director may elect to receive the deferred benefit (i) over annual periods ranging from three to 15 years and payable in quarterly installments or (ii) in a single distribution. We pay all costs and expenses incurred in the administration of the Deferred Compensation Plan. Directors also have the option to forgo 50% or more of their annual cash retainers and receive either Common Stock or restricted stock units covering shares having a fair market value on the quarterly grant date equal to

the amount of the foregone compensation. In addition, directors may defer settlement of any shares payable with respect to any restricted stock units (and any dividend equivalents) received either in lieu of the annual retainer or as the annual equity award to a later date.

#### Perquisites
We also provide our directors with a prescription drug benefit and reimburse them for the cost of education programs, transportation, food and lodging in connection with their service as directors.

We require our non-employee directors to own shares of our Common Stock to align their interests with those of the shareholders and to provide an incentive to foster our long-term success. From and after the fifth year following their Board election, non-employee directors must own stock equal in value to at least five times the annual cash retainer. We may take unusual market conditions into consideration when assessing compliance. We confirm compliance with guidelines annually at the end of each fiscal year and, as of September 30, 2022, all of our non-employee directors were in compliance with the stock ownership guidelines or had not yet completed their fifth year as a director.

## Corporate governance

#### Board corporate governance
Our Board has adopted AmerisourceBergen's corporate governance principles. Together with the charters of the Board committees, they provide the framework for the governance of AmerisourceBergen. Our corporate governance principles clearly delineate the authority and roles of the Chairman of the Board and the Lead Independent Director in the leadership of the Board, mandate the independence of the committee chairs and all the members of our Audit Committee, Compensation & Succession Planning Committee and Governance, Sustainability & Corporate Responsibility Committee, and affirm non-employee directors' access to managers and team members outside the presence of our executives. The corporate governance principles address a variety of governance issues in addition to the leadership structure, including those discussed under the headings "Information on board committees," "Code of ethics" and "Shareholder recommendations for director nominees." The Board reviews and updates the corporate governance principles and the committee charters from time to time to reflect leading corporate governance practices.

There are eight committees of the Board: five standing committees, two special committees and the Executive Committee. The five standing committees include the Audit Committee, the Compensation & Succession Planning Committee, the Compliance & Risk Committee, the Finance Committee and the Governance, Sustainability & Corporate Responsibility Committee. The special committees are the Merger Integration Committee and the Special Litigation Committee. The Merger Integration Committee was formed in March 2021 to advise and counsel management on the integration and risk management of Alliance Healthcare. In addition, the Special Litigation Committee was created in September 2020 to review and evaluate a derivative complaint related to Medical Initiatives, Inc., a subsidiary that ceased operations in 2014. The Executive Committee, which is composed of our Chairman of the Board, the Lead Independent Director and the chairs of the other committees (other than the Special Litigation Committee), has the authority to act between regularly scheduled meetings of the Board. The Chairman of the Board serves as the chair of the Executive Committee. The Board believes that changing committee assignments from time to time strengthens our corporate governance practices and enhances each committee's objective review of management.

Our Board has meaningful measures in place to facilitate strong independent oversight: the Lead Independent Director has clearly articulated and extensive authority and responsibilities in the Board's governance and functions; our Audit Committee, Compensation & Succession Planning Committee, Governance, Sustainability & Corporate Responsibility Committee, and Merger Integration Committee are each chaired by and comprised solely of independent directors; a majority of the directors serving on our Compliance & Risk Committee and

Corporate governance and related matters

Finance Committee are independent directors; and our non-employee directors are encouraged to, and often do, have direct contact with our senior managers outside the presence of our executive officers.

Our corporate governance principles and the charters of the Audit Committee, the Compensation & Succession Planning Committee, the Compliance & Risk Committee, the Finance Committee and the Governance, Sustainability & Corporate Responsibility Committee have been posted on our website at investor.amerisourcebergen.com/governance/default.aspx.

#### Board structure
Our Board provides guidance and critical review of our:

• governance,

• strategic initiatives,

• talent management, and

• risk management processes.

Our Board also ensures that we have an effective management team in place to run our business and serves to protect and advance the long-term interests of our shareholders. The role of our senior executives is to develop and implement a strategic business plan for AmerisourceBergen and to grow our business.

Our employees conduct our business under the direction of our Chairman, President and Chief Executive Officer and with the independent oversight of our Board, including our Lead Independent Director. To enhance its oversight function, our Board is composed of directors who are not employed by us, with the exception of Mr. Collis.

Our Board has always retained the flexibility to determine the optimal leadership structure for the Company and our shareholders because our shareholders benefit most when our Board has the freedom to make decisions that are in the best interests of the Company, rather than pursuant to a predetermined policy. As provided for in our corporate governance principles, if the Chairman is not an independent member of the Board, then a Lead Independent Director must be elected annually from among the independent directors by a majority vote of the independent directors. We believe that this leadership structure fosters innovative, responsive, and strong leadership for the Company as a whole.

The Board believes that it is in the best interests of the Company and its shareholders for Mr. Collis to serve as both Chairman and Chief Executive Officer at this time. Mr. Collis is uniquely suited to serve in these two roles due to his knowledge of the Company and his experience in the industry. This combined role enables him to effectively and efficiently execute our strategic initiatives, including the integration of Alliance Healthcare and PharmaLex.

As part of its succession planning efforts and in light of Dr. Henney not standing for re-election at the 2023 Annual Meeting of Shareholders, the independent directors determined that it was in the best interests of the Company and its shareholders for D. Mark Durcan to serve as the Lead Independent Director following the 2023 Annual Meeting of Shareholders. Accordingly, in fiscal 2022, the independent directors appointed Mr. Durcan as Lead Independent Director, with such appointment to be effective as of March 9, 2023. The Board believes that Mr. Durcan will provide sound independent leadership in the boardroom. He brings important skills and qualifications to the role, including substantial experience in strategic planning, global markets and technological innovation gained through his experience as a Chief Operating Officer and Chief Executive Officer of a publicly traded company and his service on public company boards. Mr. Durcan also has strong working relationships with his fellow directors.

Corporate governance and related matters

The Chairman's primary responsibility is to set the agenda for the Board in coordination with the Lead Independent Director and to facilitate communications among our directors and between the Board and senior management. As Chairman, President and Chief Executive Officer, Mr. Collis ensures that the Board's agenda and discussions address strategic planning as well as key business issues and risks that he encounters in daily operations.

Our governance structure establishes a dynamic leadership role for the Lead Independent Director which, together with independent committee leadership, provides a meaningful counterbalance to the executive Chairman and maintains independent and effective oversight of management.

The Lead Independent Director's robust and comprehensive authority is as follows:

The Board maintains processes that provide it with opportunities to examine and reassess the effectiveness of our leadership structure, including the performance of our Chairman and our Lead Independent Director. These topics are reviewed through annual evaluations, under the oversight of our Governance, Sustainability & Corporate Responsibility Committee. The Compensation & Succession Planning Committee, in accordance with its charter and under the oversight of the Lead Independent Director, will also annually review the performance of, and succession plan for, the Chief Executive Officer.

Mr. Collis has served as President and Chief Executive Officer since July 2011 and as Chairman since March 2016. Through the annual review process, the Board has determined that it remains in the best interests of the Company and its shareholders for him to serve in both roles at this time, with a Lead Independent Director serving as a counterbalance.

In November 2018, the Board determined that it was in the best interests of the Company to split the role of Chairman of the Board and Chief Executive Officer in the future, commencing with the Company's next Chief Executive Officer. At that time, the Chairman role will be assumed by an independent director.

#### Board independence

| Except for Ms. Barra (who is the Walgreens Boots Alliance designated director) and Mr. Collis (who is an executive officer of the Company), all of the directors are independent.

Corporate governance and related matters

The Board has adopted guidelines in our corporate governance principles to assist it in making independence determinations, which meet or exceed the independence requirements set forth in the NYSE listing standards. For a director to be considered independent, the Board must determine that the director does not have any direct or indirect material relationship with AmerisourceBergen.

With the assistance of legal counsel, our Board reviewed the applicable legal standards for director and Board committee member independence. In undertaking its review, the Board considered that some of our directors serve on the board of directors or as executive officers of companies for which we perform (or may seek to perform) drug distribution and other services in the ordinary course of business. As a result of this review, the Board determined that each of the following current directors and director nominees is independent:

Our Board also determined that each of the members of our Audit Committee, Compensation & Succession Planning Committee and Governance, Sustainability & Corporate Responsibility Committee are independent, in accordance with the independence requirements set forth in their charters, the applicable NYSE listing standards and the applicable rules and regulations of the Securities and Exchange Commission ("SEC"). None of the members of these committees receives any consulting or advisory fee from us other than compensation as non-employee directors.

Additionally, there are no family relationships among AmerisourceBergen's directors and executive officers.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As noted above, Dr. Henney and Mr. Long are not standing for re-election at the 2023 Annual Meeting of Shareholders.

Corporate governance and related matters

The Board executes its oversight responsibility for risk management directly and through its committees, as follows:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Our Board considers specific risk topics throughout the year, including risks associated with government regulation as well as with our strategic objectives, business plan, operations, distribution of controlled substances, information technology (including cybersecurity), ESG and capital structure, among many others. Each quarter, our Chief Financial Officer reports to the Board on AmerisourceBergen's financial performance and explains how actual performance compares to our business plan. Our corporate officers and the leaders of our principal business units report regularly to the Board about the risks and exposures related to their areas of responsibility. The Board is informed about and regularly discusses our risk profile, including legal, regulatory and operational risks to our business.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Board also oversees our compliance policies and practices, including our sophisticated diversion control program through which the Company provides daily reports directly to the Drug Enforcement Administration ("DEA") about the quantity, type, and receiving pharmacy of every order of controlled substances we distribute. Additionally, the Board periodically visits Company facilities, which provides the directors with an opportunity to observe the Company's operations and to interact with employees outside of the boardroom.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Each Board committee reports to the Board at every regular Board meeting on the topics discussed and actions taken at the most recent committee meeting. The Board discusses the risks and exposures, if any, involved in the matters or recommendations of the committees, as necessary.

• Our Compliance & Risk Committee assists the Board in its oversight of the Company's:

&nbsp;&nbsp;&nbsp;&nbsp;◦ enterprise risk management program;

&nbsp;&nbsp;&nbsp;&nbsp; ◦ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; compliance program, which includes the Office of Compliance led by the Company's Chief Compliance Officer;

&nbsp;&nbsp;&nbsp;&nbsp; ◦ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; legal and regulatory compliance; and

&nbsp;&nbsp;&nbsp;&nbsp;◦ Code of Ethics and Business Conduct.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Our Audit Committee has primary responsibility for monitoring our internal audit and financial risk assessment and overseeing our system of internal controls and financial reporting. At each regularly scheduled meeting, the Audit Committee receives reports from our:

&nbsp;&nbsp;&nbsp;&nbsp;◦ external auditor on the status of audit activities and findings; and

&nbsp;&nbsp;&nbsp;&nbsp;◦ chief audit executive (who reports directly to the Audit Committee) on the status of the internal audit plan, audit results and any corrective action taken in response to audit findings.

The Audit Committee is also responsible for periodically reviewing cybersecurity issues and the Company's business continuity and disaster recovery plans as they relate to IT security.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Board's other committees oversee risks associated with their respective areas of responsibility. For example:

&nbsp;&nbsp;&nbsp;&nbsp; ◦ &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Governance, Sustainability & Corporate Responsibility Committee oversees our sustainability strategy and practices, including the Company's ESG reporting and disclosure practices. The Governance, Sustainability & Corporate Responsibility Committee also oversees the Company's DEI practices.

&nbsp;&nbsp;&nbsp;&nbsp;◦ Additionally, the Compensation & Succession Planning Committee assesses risks associated with our compensation policies and programs for executives, as well as for employees generally.

&nbsp;&nbsp;&nbsp;&nbsp;◦ Our Finance Committee discusses risks relating to our capital structure, financing activities, dividend and tax policy and stock repurchase activities.

&nbsp;&nbsp;&nbsp;&nbsp;◦ Our Merger Integration Committee oversees risks associated with integrating the Alliance Healthcare business into our Company.

• We have a Chief Compliance Officer who oversees our corporate compliance program, including our:

&nbsp;&nbsp;&nbsp;&nbsp;◦ Office of Compliance;

&nbsp;&nbsp;&nbsp;&nbsp;◦ compliance audits;

We also have an internal Compliance Committee composed of executive officers that supports the Chief Compliance Officer in fulfilling his or her responsibilities and driving corporate adherence to our compliance program, Code of Ethics and Business Conduct and related policies and procedures. Our Chief Compliance Officer and Chief Legal Officer report to the Compliance & Risk Committee and to the full Board throughout the year on corporate compliance matters, the status of our compliance programs (including our diversion control program described below), calls to our hotline and any other material developments.

#### Oversight of employee compensation
We have conducted an internal risk assessment of our employee compensation policies and practices, including those relating to our executive officers. We have concluded that our compensation policies and practices do not promote behaviors that could put the organization at legal, financial or reputational risk. We have reviewed our risk analysis with the Compensation & Succession Planning Committee. The risk assessment process included, among other things, a review of all key incentive compensation plans to ensure that they are aligned with our pay-for-performance philosophy and include performance metrics that support corporate goals. The objective of this process was to identify any compensation plans and practices that may encourage employees to take unnecessary risks that could have a material adverse effect on the Company. No such plans or practices were identified. Accordingly, no material adjustments were made to the Company's compensation policies and practices as a result of its risk profile. Various factors mitigate the risk profile of our compensation programs, including, among others:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Performance targets under our cash incentive programs are tied to a number of different financial metrics so employees will not place undue emphasis on any particular metric at the expense of other aspects of our business;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Maximum caps on payouts have been established for our annual cash incentive programs, including under our cash bonus plan used for senior management;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Equity awards under our performance plan for executive officers have maximum caps and are forfeited entirely if the threshold performance metrics are not achieved;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For fiscal 2022, the performance plan ties 60% of an executive officer's annual equity award to performance shares that are dependent on financial metrics achieved over a three-year period to ensure that our executive officers are accountable for long-term measures of success;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The remaining 40% of an executive officer's annual equity award is in restricted stock units and also vests over a multi-year period to encourage executive officers to focus on long-term growth and creating value for shareholders;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Stock ownership requirements align the interests of our executive officers with those of our shareholders;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We have effective management processes for developing annual business plans and a strong system of internal financial controls; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A broad-based group of functions, including human resources, finance and legal, oversees aspects of our cash and equity incentive programs.

We will continue to monitor our compensation policies and practices to determine whether our risk management objectives are being met with respect to incentivizing our employees.

#### Board orientation and education
We provide our directors with comprehensive orientation and continuing education, as needed, which is overseen by the Governance, Sustainability & Corporate Responsibility Committee. Director orientation familiarizes the directors with our business and strategic plans, significant financial, accounting and risk management issues, compliance programs, policies and other controls, and our principal officers. The orientation also addresses Board procedures, our corporate governance principles and our Board committee charters. We offer continuing education programs and reimbursement for outside educational programs and provide opportunities to attend commercial director education seminars to assist our directors in maintaining their expertise in areas related to the work of the Board and the directors' committee assignments. Ongoing education includes two hours of annual compliance training for each director. We also provide our directors with full membership to the National Association of Corporate Directors to provide a forum for them to maintain their insight into leading governance practices and exchange ideas with peers.

Mr. McGee in 2018 were named to the "NACD Directorship 100," an annual honor sponsored by the National Association of Corporate Directors to recognize influential directors and others who impact corporate governance.

#### Board reviews
We have a comprehensive annual review process in place for the Board and each of its committees, which is led by the chair of our Governance, Sustainability & Corporate Responsibility Committee and our Lead Independent Director. As required by our corporate governance principles, the review occurs annually. The process involves discussion and planning for both Board succession and committee rotation, including with regard to the skills needed to continue to represent the long-term interests of shareholders.

Either the chair of our Governance, Sustainability & Corporate Responsibility Committee, the Lead Independent Director, or an independent, third-party governance expert interviews each director to obtain his or her assessment of the effectiveness of the Board and the committees on which he or she serves, as well as director performance and Board dynamics. In fiscal 2022, the evaluation process was led by the Lead Independent Director. In advance of the interview, each member of a committee receives a questionnaire soliciting feedback regarding the committee's performance. During the interview, each director is asked to provide an assessment of the Board's and the relevant committee's performance. We also solicit suggestions for improving the Board's and the committee's performance, dynamics, time-management, and functioning, as well as proposed topics of focus for the Board and the committees in the upcoming year. The results of the individual interviews and assessments are compiled in a report, which the Lead Independent Director presents to the full Board for review, discussion and determination of action items.

The annual review by the Board of the corporate governance principles and by each committee of its charter is a further step in the evaluation process through which the directors consider corporate governance best practices and trends for the Board as a whole and identify new areas of focus for the different committees. The full Board reviews and discusses recommended revisions to the corporate governance principles and committee charters prior to voting on their approval.

#### Director elections
Our bylaws and corporate governance principles provide for a majority vote standard for the election of directors. Under the majority vote standard, each director must be elected by a majority of the votes cast by the shares present in person or represented by proxy and entitled to vote. A "majority of the votes cast" means that the number of votes cast "for" a candidate for director must exceed the number of votes cast "against" that director. A plurality voting standard will apply instead of a majority voting standard if:

• A shareholder has provided us with notice of a nominee for director in accordance with our bylaws; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; That nomination has not been withdrawn on or prior to the day next preceding the date the Company first provides its notice of meeting for such meeting to shareholders.

Under Delaware law, if an incumbent nominee for director in an uncontested election does not receive the required votes for re-election, the director remains in office until a successor is elected and qualified. Our bylaws and corporate governance principles require each director nominee to tender an irrevocable resignation prior to the applicable meeting of shareholders and include post-election procedures in the event an incumbent director does not receive the required votes for re-election, as follows:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Governance, Sustainability & Corporate Responsibility Committee shall make a recommendation to the Board as to whether to accept the previously tendered resignation of the director;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Board will act on the Governance, Sustainability & Corporate Responsibility Committee's recommendation; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Board expects the director whose resignation is under consideration to abstain from participating in any decision regarding that resignation.

#### Board succession and committee rotation
We are committed to Board succession planning and recognize the value in adding directors with new perspectives to our Board. The Board review process involves discussion and planning for both Board succession and committee rotation. To support this process, the Board maintains certain policies regarding director retirement. Pursuant to our corporate governance principles, a director will offer to resign at the annual meeting of shareholders following his or her 75th birthday and a director will tender his or her resignation for consideration by the Governance, Sustainability & Corporate Responsibility Committee when his or her employment or principal business association changes materially. Additionally, a director who is an employee will resign when he or she retires or is no longer employed by us. We also encourage our Board to rotate committee chairs on a regular basis.

To further our commitment to ensuring meaningful Board refreshment, in 2022, the Board adopted a mandatory term limit, pursuant to which any director initially elected or appointed to the Board after August 18, 2022 will offer to resign at the annual meeting of shareholders following his or her 15th anniversary as a director.

## Oversight of controlled substances
AmerisourceBergen has a longstanding commitment to ensuring a safe and efficient pharmaceutical supply chain. Our wholesale pharmaceutical distribution business plays a key, but specific, role of providing safe access to thousands of important medications to enable healthcare providers to serve patients with a wide array of clinical needs across the healthcare spectrum. We have taken substantial steps to help prevent the diversion of controlled substances and are committed to joining other healthcare stakeholders, government entities, civic organizations, law enforcement agencies and individuals to help address the opioid epidemic.

#### Board oversight of risks
Our Board oversees risk management and considers specific risk topics on an ongoing basis, including risks associated with the Company's distribution of opioid medications. Our Compliance & Risk Committee provides further oversight on these matters and expertise at the Board level. The Board (and/or the Compliance & Risk Committee) receive at least quarterly updates on our anti-diversion program, the status of pending litigation related to the distribution of opioids, legislative and regulatory developments related to controlled substances, and shareholder feedback. For additional information on the Board's oversight of risks, see "Corporate governance and related matters — Corporate governance — Risk oversight and management" beginning on page 25 of this proxy statement.

**Global settlement status** <br> In February 2022, AmerisourceBergen approved a comprehensive Distributor Settlement Agreement with two other national pharmaceutical distributors to resolve opioid lawsuits filed by state and local governmental entities. The Distributor Settlement Agreement became effective in the third quarter of fiscal 2022. As of mid-January 2023, 48 of 49 eligible states as well as 99% of the eligible political subdivisions have joined the settlement. The Distributor Settlement Agreement provides meaningful relief to communities across the U.S. impacted by the opioid epidemic and will also establish a clearinghouse that consolidates data from all three distributors.<br>

#### Our role in the supply chain
Our wholesale distribution business manages the secure transportation of Food and Drug Administration ("FDA") approved medications, a small part of which includes opioids and other controlled substances, from manufacturers to neighborhood pharmacies and pharmacy chains as well as hospitals, nursing homes, hospices and other clinical settings. Distributors do not manufacture or create supply or demand for opioids. The distribution of opioid medicines represents less than two percent of our annual revenue, and we do not offer our sales team members incentives based on opioid sales.

In fulfilling our Company's purpose to create healthier futures, AmerisourceBergen is dedicated to providing efficient and safe access to all FDA-approved medications through our wholesale distribution business. Wholesale distribution serves as a physical link between manufacturers and the healthcare providers that ultimately serve patients.

#### Director attendance
Each director attended at least 75% of the aggregate of (i) the total number of meetings of the Board held during fiscal 2022 and (ii) the total number of meetings held by each committee of the Board on which such director served during fiscal 2022. There were nine meetings of the full Board during fiscal 2022, and the number of committee meetings held during fiscal 2022 is provided in the chart on page 8 of this proxy statement.

We currently expect all of our director nominees to virtually attend the 2023 Annual Meeting of Shareholders and all directors are expected to attend our annual meetings pursuant to our corporate governance principles. All of our directors virtually attended the 2022 Annual Meeting of Shareholders.

#### Meetings of the independent directors
The independent directors meet prior to the commencement of each of the regularly scheduled committee meetings. Additionally, the independent directors, together with our one additional non-management director, meet after each regularly scheduled meeting of the full Board. The Lead Independent Director presides at each such meeting and, if the Lead Independent Director is not present, the committee chairs preside on a rotating basis.

#### Communications with non-management directors
Interested parties who wish to communicate with the full Board, the non-management directors, an individual director or a Board committee may submit communications at any time in writing to: Corporate Secretary, AmerisourceBergen Corporation, 1 West First Avenue, Conshohocken, PA 19428. AmerisourceBergen's Corporate Secretary will determine, in his good faith judgment, which communications will be relayed to the Lead Independent Director and other non-management directors.

received may be reviewed by the Corporate Secretary for the sole purpose of determining whether it is appropriate. In general, the following types of communication are not related to the duties and responsibilities of the Board and are therefore not appropriate: spam and similar junk mail and mass mailings, unsolicited advertisements or invitations to conferences or promotional material, product complaints, resumes or other job inquiries, and surveys.

## Code of ethics
The Board adopted our Code of Ethics and Business Conduct in May 2004. We review and revise the Code of Ethics and Business Conduct from time to time, most recently in August 2022. It applies to directors and employees, including officers, and is intended to comply with the requirements of Section 303A.10 of the NYSE Listed Company Manual. Any waivers of the application of the Code of Ethics and Business Conduct to directors or executive officers must be approved by either the Board or the Compliance & Risk Committee.

We have also adopted our Code of Ethics for Designated Senior Officers in accordance with Item 406 of the SEC's Regulation S-K. It applies to our President and Chief Executive Officer, our Executive Vice President and Chief Financial Officer and our Senior Vice President and Chief Accounting Officer.

Our Code of Ethics and Business Conduct and our Code of Ethics for Designated Senior Officers are posted on our website at investor.amerisourcebergen.com/governance/policies/default.aspx. Additionally, any waiver or amendment to either code will be disclosed promptly on our website at investor.amerisourcebergen.com/governance/policies/default.aspx.

## Derivatives trading and hedging prohibition
AmerisourceBergen considers it improper and inappropriate for its directors, officers and employees to engage in short-term or speculative transactions in our securities, including hedging or monetization transactions. Many forms of speculative transactions are inconsistent with the goal to improve our long-term performance. Accordingly, AmerisourceBergen has a policy that prohibits directors, officers and employees from engaging in the following transactions involving AmerisourceBergen securities: short sales, hedging or monetization transactions, and transactions in publicly-traded options on our securities, such as puts, calls and other derivatives.

## Shareholder recommendations for director nominees
The advance notice provision for nomination of directors in our bylaws allows a shareholder to propose nominees for consideration by the Governance, Sustainability & Corporate Responsibility Committee by submitting specified information concerning itself and the proposed nominee, including the name, appropriate biographical information and qualifications of the proposed nominee. This and other information required under the advance notice provision must be provided to us in writing to: Corporate Secretary, AmerisourceBergen Corporation, 1 West First Avenue, Conshohocken, PA 19428, no earlier than November 10, 2023 and no later than December 10, 2023 to be considered for the 2024 Annual Meeting of Shareholders.

The proxy access provisions in our bylaws allow an eligible shareholder or group of no more than 20 eligible shareholders that has maintained continuous ownership of 3% or more of our Common Stock for at least three years to include in our proxy materials for an annual meeting of shareholders a number of director nominees up to the greater of two or 20% of the directors then in office. Loaned stock that can be recalled within three days may count towards an eligible shareholder's 3% beneficial ownership requirement, which must be maintained at least until the annual meeting at which the proponent's nominee will be considered. Proxy access nominees who do not receive at least a 25% vote in favor of election will be ineligible as a nominee for the following two years. Provisions in the Shareholders Agreement with Walgreens Boots Alliance would not permit Walgreens Boots Alliance to use proxy access. If any shareholder proposes a director nominee under our advance notice provision, we are not required to include any proxy access nominee in our proxy statement for the annual meeting. Information required under the proxy access provision must be provided to us in writing to: Corporate Secretary, AmerisourceBergen Corporation, 1 West First Avenue, Conshohocken, PA 19428, no earlier than August 30, 2023 and no later than September 29, 2023 to be considered for the 2024 Annual

## Audit Committee matters
Item 2 — Ratification of the appointment of Ernst & Young LLP as AmerisourceBergen's independent registered

public accounting firm for fiscal 2023

#### Ratification of the appointment of Ernst & Young LLP
You are voting on the ratification of the appointment of Ernst & Young LLP ("EY") as AmerisourceBergen's independent registered public accounting firm for the fiscal year ending September 30, 2023. The Audit Committee of the Board has appointed EY to serve as our independent registered public accounting firm for fiscal 2023. Although our governing documents do not require the submission of the appointment of AmerisourceBergen's independent registered public accounting firm to the shareholders for approval, the Board considers it desirable that the shareholders ratify the appointment of EY. Should the shareholders not ratify the appointment of EY as AmerisourceBergen's independent registered public accounting firm for the fiscal 2023, the Audit Committee will investigate the reasons and will reconsider whether it is appropriate to select another independent registered public accounting firm, but is not required to do so. Even if EY's appointment is ratified, the Audit Committee, in its discretion, may select a different registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and its shareholders.

#### Oversight relationship between the Audit Committee and our external auditor
Under its charter, the Audit Committee is directly responsible for the appointment, compensation, retention and oversight of AmerisourceBergen's external auditor. To execute this responsibility, the Audit Committee engages in a comprehensive annual evaluation of the external auditor's qualifications, performance and independence. In accordance with SEC rules, audit partners are subject to rotation requirements to limit the number of consecutive years an individual partner may provide service to AmerisourceBergen. For lead and concurring audit partners, the maximum number of consecutive years of service in that capacity is five years. The Audit Committee reviews the process that we and EY undertake to ensure the rotation of the audit partner responsible for reviewing the audit, and evaluates the qualifications and experience of the individual selected to serve as lead partner for our audit. EY has been retained as the external auditor of AmerisourceBergen since 2001 and of its predecessor entity AmeriSource Health Corporation since 1985. The members of the Audit Committee believe that the continued retention of EY to serve as our external auditor is in the best interests of AmerisourceBergen and its shareholders.

#### Independent registered public accounting firm services
Audit services provided by EY for fiscal 2023 will include examination of the consolidated financial statements of AmerisourceBergen and services related to periodic SEC filings. Audit services for fiscal 2023 also will include the audit of the effectiveness of our internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act of 2002. Additionally, EY may provide audit-related, tax and other services comparable in nature to the services performed in fiscal 2021 and 2022, as described under the heading "Independent registered public accounting firm's fees".

#### Representatives of the independent registered public accounting firm at the 2023 annual meeting of shareholders
Representatives of EY are expected to participate at the 2023 Annual Meeting of Shareholders. Such representatives will have an opportunity to make a statement and will be available to respond to appropriate questions.

Audit Committee matters

## Audit Committee financial experts
The Board has determined that each of Mr. Nally and Mr. Durcan is an "audit committee financial expert" as defined in Item 407(d)(5) of Regulation S-K. Mr. Nally serves as chair of the Audit Committee. A description of the financial expertise of Mr. Nally and Mr. Durcan accompanies their biographies on pages 18 and 15, respectively.

## Policy for pre-approval of audit and non-audit services
The Audit Committee's policy is to pre-approve all audit services and all non-audit services that the Company's independent registered public accounting firm is permitted to perform for the Company under applicable federal securities regulations. As permitted by the applicable regulations, the committee's policy utilizes a combination of specific pre-approval on a case-by-case basis of individual engagements of the independent registered public accounting firm and general pre-approval of certain categories of engagements up to predetermined dollar thresholds that are reviewed annually by the committee. Specific pre-approval is mandatory for the annual financial statement audit engagement, among others.

## Independent registered public accounting firm's fees
During the fiscal years ended September 30, 2022 and 2021, EY, AmerisourceBergen's independent registered public accounting firm, billed the Company the fees set forth below in connection with services rendered by the independent registered public accounting firm to the Company:

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Audit-related fees consisted of fees for assurance and related services, including employee benefit plan audits.

&nbsp;&nbsp;&nbsp;&nbsp;(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Tax fees consisted of fees for services related to tax compliance, tax advice and tax planning services.

Our Audit Committee reviewed and approved all fees charged by EY in accordance with the policy described above and monitored the relationship between audit and permissible non-audit services provided. The policy is intended to ensure that the fees earned by EY are consistent with the maintenance of the independent registered public accounting firm's independence in the conduct of its auditing functions.

Audit Committee matters

## Report of the Audit Committee
The Audit Committee consists of the three directors named at the end of this report. All of the Audit Committee members are independent under applicable SEC and NYSE rules and our corporate governance principles. The Board has concluded that each member is "financially literate" and that two of the members qualify as "audit committee financial experts." The key responsibilities of the Audit Committee are set forth in its charter, which was most recently approved by the Board in November 2022 and is available on our website at investor.amerisourcebergen.com/governance/committees/default.aspx. The Audit Committee is responsible for, among other matters, the appointment, retention, and compensation of the independent auditor and in connection therewith annually considers the performance of Ernst & Young LLP.

AmerisourceBergen's management has primary responsibility for the Company's financial statements and its internal control over financial reporting. AmerisourceBergen's independent registered public accounting firm, EY, is responsible for performing an independent audit of AmerisourceBergen's consolidated financial statements and for issuing a report on the effectiveness of AmerisourceBergen's internal control over financial reporting. The Audit Committee meets regularly with EY, with and without management present, to review the overall scope and plans for EY's audit work and to discuss the results of its audit procedures, the evaluation of AmerisourceBergen's internal control over financial reporting and the overall quality of AmerisourceBergen's accounting and financial reporting. AmerisourceBergen's management has represented to the Audit Committee that the financial statements contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 were prepared in accordance with U.S. generally accepted accounting principles and that our internal control over financial reporting was effective as of September 30, 2022.

The Audit Committee reviewed and discussed with AmerisourceBergen's management and EY the audited financial statements contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022 and our internal control over financial reporting. The Audit Committee discussed with EY, which is responsible for expressing an opinion on the conformity of the audited financial statements with U.S. generally accepted accounting principles, the firm's judgments as to the quality, not just the acceptability, of the Company's accounting principles, the reasonableness of significant judgments reflected in the financial statements and the clarity of disclosures in the financial statements. The Audit Committee also discussed with EY the matters related to the conduct of the audit that are required to be discussed with the Audit Committee under the standards of the Public Company Accounting Oversight Board ("PCAOB"), including the matters required to be discussed by the PCAOB Auditing Standard No. 1301, "Communications with Audit Committees." In addition, the Audit Committee discussed with EY the firm's independence from the Company and its management, including the matters in the written disclosures and letter that were received by the Audit Committee from EY as required by applicable requirements of the PCAOB regarding EY's communications with the Audit Committee concerning independence. The Audit Committee further considered whether the provision of non-audit related services by EY to the Company is compatible with maintaining the independence of that firm from the Company. The Audit Committee also discussed with EY the firm's audit of the effectiveness of the Company's internal control over financial reporting as of September 30, 2022.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in AmerisourceBergen's Annual Report on Form 10-K for the fiscal year ended September 30, 2022.

## Executive compensation and related matters
Item 3 — Advisory vote to approve the compensation of our named executive officers

In accordance with the requirements of Section 14A of the Exchange Act, we are including this proposal, commonly known as a "say-on-pay" proposal, which gives our shareholders the opportunity to endorse the compensation paid to our named executive officers through the following resolution:

"**Resolved**, that the shareholders approve, on an advisory basis, the fiscal 2022 compensation paid to AmerisourceBergen's named executive officers, as disclosed in AmerisourceBergen's proxy statement for the 2023 Annual Meeting of Shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the executive compensation tables and the related narrative discussion."

In deciding how to vote on this proposal, we encourage you to read the "Compensation Discussion and Analysis" section beginning on page 44 for a detailed description of our executive compensation philosophy

and programs, the compensation decisions of the Compensation & Succession Planning Committee under those programs and the factors considered in making those decisions.

AmerisourceBergen's executive compensation program is strongly focused on pay for performance principles. We emphasize a compensation philosophy that rewards our executives when they deliver targeted financial results and subjects a significant portion of their compensation to risk if they do not. The compensation of our named executive officers varies depending upon the achievement of pre-established performance goals. Through stock ownership requirements and equity incentives, we also align the interests of our executives with those of our shareholders and the long-term interests of AmerisourceBergen. Our executive compensation policies have enabled AmerisourceBergen to attract and retain talented and experienced executives and have benefited AmerisourceBergen over time.

We believe that the fiscal 2022 compensation of our named executive officers is reasonable and competitive, aligns with AmerisourceBergen's fiscal 2022 results and positions us for future growth.

We are asking our shareholders to indicate their support for the compensation of our named executive officers as described in this proxy statement. Because your vote is advisory, it will not be binding upon the Board; however, the Board values shareholders' opinions, and the Compensation & Succession Planning Committee will take into account the outcome of the vote when considering future executive compensation decisions. The Board has adopted a policy providing for annual say-on-pay advisory votes. The Company has included in this proxy statement a proposal regarding the frequency of the say-on-pay advisory vote ("say-on-frequency" vote) and the Board has recommended that the shareholders vote "every year" to approve an annual say-on-pay vote. Unless the Board modifies the Company's policy, the next say-on-pay advisory vote will be held at our 2024 Annual Meeting of Shareholders and the next say-on-frequency advisory vote will be held at our 2029 Annual Meeting of Shareholders.

Executive compensation and related matters

## Letter from the Compensation & Succession Planning Committee

#### Dear AmerisourceBergen shareholders,
As members of AmerisourceBergen's Compensation & Succession Planning Committee (the "Compensation Committee"), we thank you for your continued investment in AmerisourceBergen as we establish goals that support long-term growth and enable the Company to create healthier futures. The Compensation Committee appreciates the feedback from shareholders and embraces a compensation philosophy that aligns with their interests, puts a significant portion of executive compensation at risk, and attracts and retains talented and experienced executives.

#### Business performance and strategic achievements
The Compensation Committee recognizes the Company's strong performance in a particularly challenging macroeconomic environment. In fiscal 2022, the Company delivered on its strategic imperatives and further strengthened its value proposition to its healthcare partners, from manufacturers to patients. The management team continued to drive growth and expand its leadership position in distribution through the continued integration of Alliance Healthcare and the announcement of its intent to acquire PharmaLex, a leading provider of specialized services for the life sciences industry.

We are proud of the Company's accomplishments in distributing COVID-19 treatments, vaccines, and test kits to hospitals and health systems globally, the focus on fostering a world-class employee experience, progress on ESG efforts, and the creation of long-term shareholder value, as described in this proxy statement. The Compensation Committee's decisions for the fiscal year align with these performance outcomes and achievements and reflect the continued strong execution of the management team, the value of differentiated solutions, and the resilience of the businesses.

#### Shareholder engagement
The Compensation Committee participates in robust shareholder engagement and finds feedback from these conversations to be valuable and informative inputs in our decision-making process. During the fall engagement, we reviewed fiscal 2022 program changes, previewed the proposed metrics for the fiscal 2023 program, and emphasized our commitment to hold the management team accountable for events within their control. In these discussions, shareholders confirmed that they found recent actions to be responsive to the feedback they provided in the prior fiscal year, as evidenced by the 96% support for our Say-on-Pay proposal at our 2022 Annual Meeting of Shareholders.

#### Fiscal 2022 Committee actions
During the course of the year, the Compensation Committee evaluated the Company's performance and achievements and took actions to address feedback raised by shareholders.

2022 program enhancements included the following:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Relative total shareholder return ("TSR") modifier in the performance share component of the long-term incentive plan with above-median performance required for a target payout;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Post-vesting holding requirement on 50% of earned performance shares of two years for the CEO and one year for other named executive officers;

• Quarterly review of the adjustments in the Company's reported financial results;

• Enhanced incentive compensation clawback provisions and disclosure; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Continued to enhance disclosure of the Compensation Committee's decision-making process.

At the conclusion of fiscal 2022, we approved payouts for our named executive officers after considering a number of factors, including the Company's business performance and its strong execution against strategic objectives. We also considered our decision last year to exercise negative discretion on the fiscal 2021 short-term incentive payouts, and a commitment that, absent a material change to the factors considered, we did not intend to take future discretionary action related to the resolution of opioid-related litigation.

#### Looking ahead
In keeping with our commitment, we are incorporating an ESG metric into the executive compensation program that furthers the Company's business objectives and aligns to the pillars of the Company's ESG strategy. The ESG metric, effective for fiscal 2023, includes three quantifiable components focused on driving female representation in leadership roles globally, employee inclusion and engagement, and business resiliency planning for climate-driven events. This new metric represents 10% of our executives' short-term incentive opportunity.

The Compensation Committee remains committed to establishing appropriate incentives for our business leaders and driving accountability for performance and we look forward to ongoing dialogue with our shareholders on these topics.

#### Shareholder engagement and our 2022 say-on-pay vote
**At our 2022 Annual Meeting of Shareholders, our say-on-pay proposal received approximately 96% support.** The Board and Compensation Committee are encouraged by this strong level of shareholder approval and interpret this as an endorsement of our current compensation program and fiscal 2021 compensation decisions.

In addition to vote outcomes, regular shareholder outreach and engagement are critical inputs, which are shared with our full Board and management to help inform their decision-making process. We engage with shareholders throughout the year to seek their feedback on our governance and executive compensation practices, in addition to other topics important to our long-term growth and value creation.

As demonstrated in the chart below, we engaged with our largest shareholders, as well as proxy advisory firms and industry groups, and in certain meetings, included the chairs of our Compensation Committee and our Governance, Sustainability & Corporate Responsibility Committee.

![[MISSING IMAGE: tm2227032d1-pc_outreachpn.jpg]](tm2227032d1-pc_outreachpn.jpg)

#### Shareholder feedback themes
We discussed a range of important topics with shareholders during fiscal 2022, including executive compensation, Board and committee composition and succession planning, ESG initiatives, and human capital disclosure.

Throughout these engagements, the Compensation Committee received positive feedback for compensation actions it took last year, including:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The addition of a relative TSR modifier to the 2022 performance share awards, with above median performance required for a target payout;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The implementation of a post-vesting holding requirement on 50% of earned performance shares of two years for our CEO and one year for our other named executive officers, beginning with fiscal 2022 awards;

• Enhanced disclosure around the Compensation Committee's decision-making process; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The decision to apply negative discretion to fiscal 2021 cash bonus payouts in light of the opioid litigation settlement accrual.

We also previewed the addition of an ESG metric in our 2023 short-term cash incentive program, as described on page 54 in the "Looking ahead: Fiscal 2023 cash bonus" section. We discussed with shareholders how we:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Honored our commitment to incorporate an ESG metric into the executive compensation program;

• Purposefully selected a metric that is measurable and objective;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Identified three sub-components in the categories of gender representation in leadership, employee inclusion and engagement, and business resiliency planning for climate-driven events; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Plan to include this metric in the fiscal 2023 short-term incentive and use the first year as a learning opportunity for future design.

We heard support for the ESG metric from our shareholders, including for our efforts to incorporate ESG in a way that is aligned with our business.

#### Fiscal 2022 compensation design
**We seek to pay our executive officers fairly and competitively and to link pay with performance. The main elements of our compensation program are base salary, a short-term incentive in the form of an annual cash bonus, and long-term equity incentive awards.** We emphasize compensation opportunities that reward our executive officers when they deliver on targeted results and strategic objectives. When setting executive compensation, the Compensation Committee takes into account job performance, scope of role, duties and responsibilities, expected future contributions, peer group, other market pay data, and internal equity.

**A significant portion of our executive officers' compensation is incentive-based.** In fiscal 2022, incentive compensation (annual cash bonus and equity incentive awards) accounted for approximately 91% of our CEO's total target direct compensation and approximately 81% of the average total target direct compensation of the other named executive officers.

We believe that the fiscal 2022 compensation of our executive officers was aligned with both AmerisourceBergen's fiscal 2022 adjusted results and our compensation objectives. Our compensation policies are designed to attract and retain talented and experienced executive officers. We believe that these policies have benefited AmerisourceBergen over time and will position us for growth in future years.

#### Compensation practices and policies
**We believe our executive pay is reasonable and provides appropriate incentives to our executive officers to achieve our financial and strategic goals without encouraging them to take excessive risks in their business decisions. The Board and its committees regularly evaluate major risks to our business, including how risks taken by management could affect the value of executive compensation.**

#### Compensation details
**The Compensation Committee seeks to design an executive compensation program that incentivizes our management team to meet and exceed rigorous objectives that drive long-term value for all our stakeholders while promoting talent retention. Our named executive officers' total direct compensation consists of three components:**![[MISSING IMAGE: tm2227032d1-tbl_compenpn.jpg]](tm2227032d1-tbl_compenpn.jpg)

A substantial majority of this compensation is at risk and tied to the performance of the Company and its share price. Base salary is the only fixed compensation. The Compensation Committee considers a multitude of factors in determining executive compensation objectives and targets for our named executive officers, which are described in detail in the following sections.

#### Compensation philosophy
The Compensation Committee supports a compensation philosophy for our named executive officers that:

---

| | |
|:---|:---|
| Aligns with long-term shareholder interests | &nbsp;&nbsp;&nbsp; • A substantial majority of our named executive officer compensation is equity-based <br>• The majority of equity compensation has a three-year performance period <br>• Our executives are subject to stock ownership guidelines <br>• The Compensation Committee may exercise discretion <br>|
| Puts a significant portion of compensation at risk  | &nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Approximately 91% of CEO and approximately 81% of other named executive officer total direct compensation is at risk<br>• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Outcomes are tied to the achievement of rigorous predetermined metrics <br>|

#### Setting executive compensation

#### Role of the Compensation Committee
Our Compensation Committee is composed of independent directors. The Compensation Committee is responsible for the design of our executive compensation program, oversight of our incentive plans, and review of our executive talent development strategy and succession planning. The Compensation Committee reviews and approves the individual elements of compensation of our executives, including our named executive officers, as well as the design of and awards made under our long-term incentive plan. The Compensation Committee also oversees our savings, retirement, health and welfare plans and has delegated the administration of our benefit plans to an internal Benefits Committee, composed of senior finance, human resources and legal executives. The internal Benefits Committee also oversees the selection of investment options under our savings plans and the performance of the investment advisers and plan administrators.

#### Meetings
The Compensation Committee met six times in fiscal 2022. The Compensation Committee chair, in consultation with the other Compensation Committee members and management, prepares agendas that address an annual calendar of topics and other matters. The Compensation Committee meets without management present, whenever necessary, to discuss matters it deems appropriate.

#### Role of external compensation consultant
The Compensation Committee has sole authority to retain and terminate any consultant or other external advisor, and to approve the fees and other terms of engagement for such consultant or advisor. Each year, the Compensation Committee evaluates the qualifications, performance, independence and potential for conflicts of interest of its compensation consultant and any other external advisors to the Compensation Committee. This evaluation takes place at the beginning of the fiscal year in the case of an ongoing engagement or prior to the selection of a new consultant or advisor.

Pearl Meyer & Partners ("Pearl Meyer") serves as the Compensation Committee's compensation consultant. The Compensation Committee has determined that Pearl Meyer and the individual Pearl Meyer consultants are independent and have not had any economic interests or other relationships with AmerisourceBergen or the Compensation Committee members that would conflict with their obligation to provide the Compensation Committee with impartial and objective advice. Pearl Meyer did not provide any services to our management in fiscal 2022.

Executive compensation and related matters

The Compensation Committee's independent compensation consultant advises the Compensation Committee on all aspects of executive compensation, including:

• comparative data;

• competitive positioning of executive pay;

• plan design;

• long-term incentive pay practices; and

• market trends.

As directed by the Compensation Committee, the consultant prepares analysis and recommendations relating to the compensation of our executive officers, including pay recommendations for our Chief Executive Officer. Representatives of Pearl Meyer attended Compensation Committee meetings and met privately from time to time with the Compensation Committee and individual Compensation Committee members to plan for Compensation Committee meetings and discuss executive compensation matters.

#### Role of management
Our Chief Executive Officer gives the Compensation Committee a performance assessment and pay recommendation for senior management, including each of the other named executive officers. Management, in consultation with the Compensation Committee's compensation consultant, may also make recommendations on matters of compensation philosophy and plan design. Executives may attend the Compensation Committee meetings, but they are not present when the Compensation Committee meets in executive session and they do not make recommendations regarding their own pay.

#### Peer group determination
Each year, the Compensation Committee, in consultation with its independent compensation consultant, evaluates a peer group of companies that will serve as a reference for comparing the pay of our named executive officers to the market. We assess companies that best reflect the complexity of our industry and competition for customers, shareholders and talent to determine whether our level of executive pay is appropriate when compared to industry and market standards. We also conduct a detailed market review of executive pay to evaluate each element of pay and benefit competitiveness, review pay practices, and compare performance against our peer group.

Our peer group consists of companies with business models and operations comparable to our own, including our two largest direct competitors, and companies that we believe have a similar financial and operational profile. Metrics used to select our peer group include: revenue; market capitalization; number of employees; net income; operating income margin; and return on invested capital.

Following review with its independent compensation consultant in fiscal 2022, the Compensation Committee concluded that our current peers remained appropriate. This peer group included:

Executive compensation and related matters

The Compensation Committee reviews peer group proxy statement data in evaluating our Chief Executive Officer's pay and published compensation survey data in evaluating our other named executive officers' pay. When assessing pay levels, the Compensation Committee also reviews our executive officers' compensation in relation to each other. The Compensation Committee's independent consultant concluded that our overall competitive posture for executive pay in fiscal 2022 remained aligned with our pay for performance compensation philosophy.

#### Fiscal 2022 executive compensation program
Our executive compensation program consists of three core components: base pay, short-term incentives, and long-term incentives, with the majority of compensation being at risk and performance-based. The Compensation Committee's decisions regarding the fiscal 2022 pay program are described in detail below.

#### Base Salary
Base salary is intended to provide a regular stream of income and security. The Compensation Committee takes into account a variety of factors, including scope of role, duties and responsibilities, expected future contributions, our pay philosophy, peer group and other market data, and internal pay equity.

In fiscal 2022, we made adjustments to our NEOs' base salaries, as shown below, for the reasons cited above and to better align their base salaries with the median of the peer group.

---

| | |
|:---|:---|
| **Executive**  | **Increase % in base salary for fiscal 2022**  |
| Mr. Collis | 0% |
| Mr. Cleary | 3% |
| Mr. Mauch | 6% |
| Ms. Clark | 3% |
| Ms. Battaglia | 6% |

---

#### Short-term cash incentive
**Our short-term incentive plan is intended to both motivate executives to improve financial performance year-over-year and reward executive officers who deliver on targeted financial results.** 

For fiscal 2022, the Compensation Committee did not adjust the target cash bonus incentive levels for our named executive officers, which were 165% of base salary for the CEO and 100% of base salary for the other named executive officers.

Each year, the Compensation Committee selects enterprise-level performance measures that it believes are the key metrics used by management to set business goals and for shareholders to evaluate our financial results. Consistent with recent prior years, the Compensation Committee chose the following metrics:

![[MISSING IMAGE: tm2227032d1-tbl_matricpn.jpg]](tm2227032d1-tbl_matricpn.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Adjusted Operating Income, Adjusted EPS and Adjusted Free Cash Flow are non-GAAP financial measures. See Appendix A for definitions and additional information regarding non-GAAP financial measures.

2023 proxy statement **51**

[**TABLE OF CONTENTS**](#TOC2)

Executive compensation and related matters

Each year, the Compensation Committee also sets goals for these performance measures that it views to be rigorous, based on Company and market outlook and, in most cases, that reflect growth over prior year results and targets. In November 2021, the Compensation Committee approved the following enterprise-level performance goals for our fiscal 2022 cash incentive plan, for each of which there is a threshold, target and maximum goal, which measures performed as follows:

![[MISSING IMAGE: tb_perform-pn.jpg]](tb_perform-pn.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Adjusted Operating Income, Adjusted EPS and Adjusted Free Cash Flow are non-GAAP financial measures. See Appendix A to this proxy statement for additional information regarding non-GAAP financial measures, including GAAP to non-GAAP reconciliations.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Actual results between threshold and target are calculated by straight line interpolation. Actual results above target are calculated based on the "stretch" bonus, equal to an additional 5% for every 1% that actual performance exceeds target, up to a maximum of 200%.

Fiscal 2022 cash bonus payouts

Because AmerisourceBergen exceeded the target amounts for the corporate-level performance goals and delivered strong business performance and strategic execution in fiscal 2022, each of the named executive officers earned a stretch bonus in accordance with the terms of our Annual Incentive Plan ("AIP"). After reviewing the Company's achievement of financial and strategic objectives and robust discussion after fiscal year-end, the Compensation Committee determined that it would not apply discretion to reduce fiscal 2022 cash bonus awards for the named executive officers.

![[MISSING IMAGE: tm2227032d1-eq_payoutpn.jpg]](tm2227032d1-eq_payoutpn.jpg)

Target and actual fiscal 2022 cash bonuses for our named executive officers were as follows:

---

| | | | | | | | | | |

| **Name**  | **Base salary<br>($)**  | **x**  | **AIP%**  | **=**  | **AIP target<br>($)**  | **x**  | **Payout level%**  | **=**  | **Calculated payout<br>($)**  |

| Robert P. Mauch | 850000 | x | 100% | = | 850000 | x | 139.2% | = | $1183131 |
| Gina K. Clark | 620000 | x | 100% | = | 620000 | x | 139.2% | = | $862990 |
| Silvana Battaglia | 580000 | x | 100% | = | 580000 | x | 139.2% | = | $807313 |

Consideration of Non-GAAP Free Cash Flow in compensation decisions

AmerisourceBergen uses non-GAAP financial measures to perform financial planning and to evaluate the Company's operating performance. We also furnish the same non-GAAP measures to investors on a quarterly basis. Our annual cash bonus plan uses the same non-GAAP measures that management uses internally and that we publicly disclose, which we believe provides consistency and transparency between our financial reporting and compensation outcomes and effectively measures and rewards operational performance. Those measures reflect adjustments made based on predetermined and publicly disclosed criteria, including for certain items that are unpredictable.

AmerisourceBergen's publicly reported non-GAAP financial results are presented to the Compensation Committee quarterly, along with reconciliations to GAAP, and are the starting point for the Compensation Committee's annual executive compensation decisions. As part of its year-end review, the Compensation Committee determines any discretionary modifications that it wants to make to our publicly reported non-GAAP financial results based on criteria such as materiality, accountability, scope and precedence.

At the time that the Board approved the Company's fiscal 2022 budget, the Company was negotiating a complex, industry-wide settlement of opioid litigation that contemplated payments over an 18-year period. It was uncertain whether or when the settlement would be reached, as well as the specific payment amounts that would be disbursed in each fiscal year if achieved.

As a result, at the beginning of fiscal 2022, the Compensation Committee approved using an adjusted Free Cash Flow target in the short-term incentive that did not include payments associated with the potential settlement. That decision was made in accordance with the Company's publicly disclosed definition of adjusted Free Cash Flow because the payments were not predictable at the time the short-term incentive targets were set.<sup>(1)</sup> Subsequently, the Company, two other national pharmaceutical distributors, and numerous state and local governmental entities approved a Distributor Settlement Agreement midway through fiscal 2022. After the Distributor Settlement Agreement became effective in the third quarter of fiscal 2022, the first two of the 18 annual payments were made under the agreement during fiscal 2022.

In determining compensation decisions for fiscal 2022, the Compensation Committee determined not to make any discretionary adjustments to our non-GAAP Free Cash Flow results, given the context in which the targets were set. In doing so, the Compensation Committee also considered the impact of its decision to exercise negative discretion on the fiscal 2021 cash bonus payouts for our CEO and other named executive officers to reflect the shareholder experience related to the opioid litigation accrual recorded in fiscal 2020.

Beginning in fiscal 2023, the Company's budget and the short-term incentive goals include settlement payments for years three to 18 that will be made under the Distributor Settlement Agreement because the payments are now predictable, and no adjustments will be made to Free Cash Flow for those payments.

(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The Company defines the non-GAAP measure of adjusted Free Cash Flow as:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • net cash provided by operating activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; excluding significant unpredictable or non-recurring cash payments or receipts relating to legal settlements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • minus capital expenditures.

#### Long-term equity incentives

---

| | |
|:---|:---|
| **We use equity awards to motivate our executive officers to achieve superior business results over the long term. Equity awards support our stock ownership requirements and further enhance the alignment of management and shareholder interests. The annual equity award for our executive officers is allocated as 60% performance shares and 40% restricted stock units.** <br> Restricted stock units vest ratably each year during the three-year vesting period, while performance shares have a three-year performance period. In addition, equity awards are subject to vesting, ownership and retention requirements, and forfeiture and clawback provisions, as described in more detail below and in the sections following the Summary Compensation Table.  | ![[MISSING IMAGE: tm2227032d1-pc_eqincpn.jpg]](tm2227032d1-pc_eqincpn.jpg)  |

Fiscal 2022 equity incentives

![[MISSING IMAGE: tm2227032d1-tbl_excomppn.jpg]](tm2227032d1-tbl_excomppn.jpg)

We believe that it was appropriate to award this amount of equity incentives to our named executive officers because they are in the best position to drive our future results and implement our long-term business strategy.

In approving fiscal 2022 long-term equity incentive awards, the Compensation Committee considered several factors, including:

• skills, experience, and time in role • expected future contributions • Company performance • market alignment • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; having the majority of NEO pay at risk • average annual share burn

Fiscal 2022 long-term incentive equity awards were granted on November 10, 2021. Ms. Battaglia's fiscal 2022 long-term incentive equity award included an additional 4,775 restricted stock units in recognition of her leadership role in the integration of new employees from the acquisition of Alliance Healthcare.

Performance share awards

Our performance plan is designed to encourage our executive officers to focus on initiatives that promote the achievement of our long-term goals. Performance share awards are granted annually and cover a three-year performance period. Performance shares are subject to the attainment of predetermined rigorous goals approved by the Compensation Committee. Specific targets for these goals are disclosed retroactively to avoid the potential for competitive harm. Vesting (or payout of shares) is based on performance at the end of the applicable three-year performance cycle.

In consideration of feedback received from shareholders, the Compensation Committee added the following features to our fiscal 2022 performance share awards:

1. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A relative TSR modifier with above median performance required for a target payout, as described in more detail below; and

2. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A post-vest holding requirement on 50% of earned performance shares of two years for the CEO, and one year for the other named executive officers.

A participating executive officer has the opportunity to earn a payout of between 0% and 200% of his or her target award, as follows, for each metric:

![[MISSING IMAGE: tm2227032d1-lc_paypn.jpg]](tm2227032d1-lc_paypn.jpg)

Fiscal 2022 performance shares metrics

The Compensation Committee selected the following metrics for performance shares granted in fiscal 2022, which covers the three-year performance period beginning October 1, 2021 and ending September 30, 2024:

![[MISSING IMAGE: tm2227032d1-tbl_shrmatpn.jpg]](tm2227032d1-tbl_shrmatpn.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; TSR is calculated as share price appreciation (or reduction) over the performance period, including reinvestment of dividends when paid, divided by the share price at the beginning of the period. The value of performance shares awarded will be decreased or increased by up to 15% based on this relative TSR measure. In the event of a negative absolute AmerisourceBergen TSR over the 3-year period, payout is capped at 100% of target, regardless of whether actual performance is above target for compound annual adjusted EPS group or average annual adjusted ROIC.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The S&P 500 Healthcare Providers & Services Index currently includes:

The Compensation Committee believes the goals set for these performance shares are challenging and difficult to achieve, but attainable with significant skill and effort on the part of our executive leadership team and consistent with our long-range plan. The specific goals for all of our outstanding performance share awards are confidential competitively sensitive information.

Outstanding performance shares

As disclosed in last year's proxy statement, the fiscal 2021-fiscal 2023 performance shares have the design shown above, including the relative TSR modifier.

Fiscal 2020 performance share payouts (fiscal 2020-fiscal 2022 performance period)

In November 2019, each of our named executive officers received performance shares for the three-year performance period spanning fiscal 2020 through fiscal 2022. In November 2022, the Compensation Committee approved the vesting and payment of these performance shares based on AmerisourceBergen's achievement of a Compound Annual Adjusted EPS growth rate of 15.87% and an Average Annual Adjusted ROIC of 19.47%, in each case, for the performance period ending September 30, 2022, which aggregated to 195.6% of target, calculated as follows:

![[MISSING IMAGE: tm2227032d1-tbl_relmatpn.jpg]](tm2227032d1-tbl_relmatpn.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Compound Annual Adjusted EPS Growth is the mean annual growth rate of adjusted EPS from the baseline over the three-year performance period.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Average Annual Adjusted ROIC is calculated by taking the average of the Company's annual adjusted ROIC during the three-year performance period. Annual Adjusted ROIC is calculated by dividing after-tax adjusted operating income by invested capital.

Based on our performance, and the respective weighting of each performance metric, the number of shares earned for the fiscal 2020 through fiscal 2022 performance period was calculated as follows:

#### Other compensation elements

#### Benefits and other compensation elements
Other compensation

Our named executive officers receive a limited number of other benefits as part of a competitive compensation package, which constitutes in the aggregate only a small percentage of their total compensation. As discussed below, these benefits include:

• participation in our group health and welfare plans, which is generally available to all employees;

• a Company matching contribution under our 401(k) plan, which is available to all employee participants;

• participation in a deferred compensation plan, which is available to senior management;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; a Company matching contribution under our benefit restoration plan, which is available to select key management, to address matching contributions on compensation above the 401(k) limit;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; an allowance for tax and financial planning services for our executive officers to enable them to focus more of their time and attention on achieving our financial and strategic goals and assist them in maximizing the benefits offered to them;

• a physical examination benefit to promote the health and wellness of our key leaders; and

• for our CEO, certain security and driver services.

General employee benefits

Core employee benefits are available to the executive officers on the same basis as all domestic employees generally. These benefits include medical and dental coverage, disability insurance, life insurance, and a 401(k) plan that includes a Company match.

Deferred compensation

Executive officers may defer receipt of part of their cash compensation under our deferred compensation plan. The plan is intended to promote retention of executive officers by providing a long-term, tax-efficient savings opportunity at a low cost to the Company. Amounts deferred under the plan are deemed invested in the plan investment option(s) chosen by the participant. The participant's account is adjusted for any notional gains and losses on the amounts deferred under the plan.

Benefit restoration plan

We offer a benefit restoration plan to selected key management, including the named executive officers. We implemented this plan in 2006 to address the absence of any non-legacy executive retirement plan following the 2001 merger that formed the Company and to permit executive officers to receive the full amount of the Company match generally available to other employees under the 401(k) plan. In fiscal 2022, the benefit restoration plan provided an annual contribution amount equal to 4% of a participant's salary and bonus to the extent that his or her compensation exceeded Internal Revenue Service (IRS) limits applicable to our 401(k) plan. Benefits under the plan are subject to certain vesting requirements based on age and length of service (other than in the event of death, disability or a change in control).

#### Severance and change in control benefits
Looking ahead: Executive Severance Policy

 **Following discussions with investors, in fiscal 2023 the Compensation Committee adopted a new executive severance policy that applies to any employment or severance agreement that is amended or entered into with an executive officer following the policy's November 9, 2022, effective date. Under the terms of the policy, cash-based severance benefits for involuntary terminations must be limited to an amount equal to 2.99 times the executive's base salary, plus the executive's target annual bonus, unless the employment or severance agreement receives shareholder approval. The policy applies to all individuals designated by the Board as "officers" under Rule 16a-1(f) of the Exchange Act. The Compensation Committee believes that this policy will serve to carefully balance the interests of shareholders with the Company's needs to remain competitive in the market.**

<br> Employment agreements

Employment agreements in effect during fiscal 2022 for our named executive officers are described under "Executive compensation and related matters — Employment agreements." Our standard employment agreements for executive officers cover termination (including in the event of a change in control) and severance and include non-competition, confidentiality, and related provisions. The employment agreements do not include specified amounts of salary, bonus opportunities, or equity-based compensation for future years.

Severance benefits

We provide severance benefits under specified circumstances to give executive officers a measure of financial security following the loss of employment, to protect the Company from competitive activities after the departure of certain executive officers, and because we believe that these benefits are important to attract and retain our executive officers in a competitive industry. We will provide severance benefits if we discharge an executive officer without cause or such executive officer leaves the Company with good reason, each as defined in the applicable employment agreement. The terms of the severance benefits for our named executed officers are set out in employment agreements and various plans, which are described in the section of this proxy statement titled "Executive compensation and related matters — Potential payments upon termination of employment or change in control."

We do not provide severance benefits if an executive officer is terminated for cause or leaves without good reason. In that case, we would only pay the amount of accrued obligations.

Change in control

Our equity awards have a "double-trigger" change in control feature, whereby the vesting of equity awards will be accelerated if an executive officer's employment is involuntarily terminated upon or within two years after a change in control. In the event of a change in control, a shortened performance period, which extends only through the end of the fiscal quarter preceding the change in control, will be used to determine the payout under awards of performance shares. We provide these benefits to offer some financial protection to employees following an involuntary loss of employment in connection with a change in control and to enable our executive officers to focus on important business decisions should we be acquired without regard to how the transaction may affect them personally. We believe that this structure provides executive officers with an appropriate incentive to cooperate in completing a change in control transaction. The Board and the Compensation Committee also have discretion under our equity plans to take certain actions in the event of a change in control. These actions include: canceling options that are not exercised within a specified period; cashing out outstanding options; canceling any restricted stock unit awards in exchange for the payment of cash, property or a combination of cash and property equal to the award's value; or substituting other property (including securities of another entity) for awards granted under our equity plans.

In addition, the Compensation Committee has discretion under the AIP to pay the annual cash incentive awards during any year in which a change in control occurs. If this discretion is exercised, bonus payments would be made at target level and/or based on performance for the portion of the fiscal year until the change in control event and paid within 75 days of the change in control.

Executive compensation and related matters

Under our Benefit Restoration Plan, any unvested amounts will vest immediately upon a change in control.

Under the employment agreements for our executive officers, if amounts otherwise payable to an executive officer in connection with a change in control would constitute excess parachute payments within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the "Code"), the Company will reduce such payments to an amount that would avoid any excise taxes under Section 4999 of the Code, but only if such reduction would provide the executive officer with a greater net after-tax benefit than would no reduction.

Additionally, an executive officer may receive additional severance if his or her employment is involuntarily terminated without cause or such executive officer leaves the Company with good reason upon or within two years following a change in control. See the section of this proxy statement titled *"*Executive compensation and related matters — Potential payments upon termination of employment or change in control" below.

#### Executive compensation governance
Compensation forfeiture and recoupment ("clawback") provisions

In December 2021, the Compensation Committee adopted a comprehensive Compensation Recoupment Policy aimed at enhancing and updating the Company's existing clawback provisions. The Compensation Recoupment Policy applies to incentive-based cash and equity compensation granted to covered participants after December 9, 2021, the effective date of the Compensation Recoupment Policy. The clawback provisions of the 2014 Omnibus Incentive Plan continue to apply to grants made under that plan. The current Omnibus Incentive Plan and the AIP incorporate the Compensation Recoupment Policy by reference.

The Compensation Recoupment Policy provides for forfeiture or recoupment of certain cash and equity incentive compensation in the event of a restatement of our financial statements or detrimental conduct that occurs after the effective date of the Compensation Recoupment Policy. Specifically, forfeiture or recoupment is authorized if any of the following occur (each, a "covered event"):

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; A covered participant engages in misconduct that results in a restatement of our financial statements, due to a material error, during the covered participant's employment or within three years thereafter; or

• A covered participant:

&nbsp;&nbsp;&nbsp;&nbsp;(i) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; is terminated for cause, or the Compensation Committee determines that that the covered participant committed an act during employment that was not discovered until after termination of such employment and that would have been grounds for termination for cause;

&nbsp;&nbsp;&nbsp;&nbsp;(ii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; breaches a confidentiality, non-solicitation, non-competition, non-disparagement or inventions assignment covenant with AmerisourceBergen;

&nbsp;&nbsp;&nbsp;&nbsp;(iii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; materially breaches an employment or service agreement or any of our employment, insider trading, or ethics policies or our Code of Ethics and Business Conduct;

&nbsp;&nbsp;&nbsp;&nbsp;(iv) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; fails to cooperate in any investigation or legal proceeding; or

&nbsp;&nbsp;&nbsp;&nbsp;(v) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; commits fraud, gross negligence or willful misconduct in the course of employment that adversely affects our business or affairs.

The Compensation Recoupment Policy applies to our officers as defined under Section 16 of the Exchange Act and any other individual receiving an equity grant under our Omnibus Incentive Plan or a successor plan. In the event of a covered event under the Compensation Recoupment Policy, the Compensation Committee may require forfeiture or recoupment of outstanding equity or cash incentive compensation that vests or is distributed within one year prior to, or three years following, the covered event. The Compensation Committee has discretion to determine the method of recovering compensation and the amount to be recovered. We intend to modify the Compensation Recoupment Policy as necessary to comply with the final rules issued under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 with respect to clawback policies.

In addition, in connection with the previously disclosed Corporate Integrity Agreement with the Office of Inspector General of the Department of Health and Human Services, we maintain a Financial Recoupment Policy, which will continue through September 2023. Under this policy, cash and equity compensation awarded to executive officers and senior employees in certain businesses are subject to additional forfeiture and

Executive compensation and related matters

clawback provisions. The Compensation Recoupment Policy does not affect the Corporate Integrity Agreement, the Financial Recoupment Policy, or any recoupment provisions that may apply under our other agreements or plans.

Clawback disclosure policy

The Company has a clawback disclosure policy that applies to all incentive compensation made to any officer (as such term is defined under Section 16 of the Exchange Act) under the Company's Omnibus Incentive Plan and AIP. Under the policy, if incentive compensation is ever forfeited or required to be repaid by an officer and the underlying event has been publicly disclosed, then we will disclose the aggregate amount forfeited or to be repaid. The disclosure will include a general description of the circumstances giving rise to the clawback and will be made in a document filed publicly with the SEC or posted to a clearly identifiable location on our investor website at investor.amerisourcebergen.com.

The disclosure policy is subject to exceptions:

(i) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if such disclosure would violate an individual's privacy rights;

(ii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if such disclosure would result in or exacerbate existing or threatened litigation; or

(iii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; if such disclosure is contrary to law or regulation.

The policy is administered by the Board, which has exclusive authority to interpret and carry out the policy.

Equity award grant practices

We have a written policy on equity grants designed to formalize our equity grant practices and ensure that equity awards will generally be made at specified times. Our equity award policy is designed to encourage consistency in practice, but is not intended to and does not limit the authority of the Compensation Committee under our equity incentive plans, including the Omnibus Incentive Plan. The Compensation Committee generally will review and approve annual equity awards to executive officers and other eligible employees in November of each year, which is near the beginning of our fiscal year. This allows the Compensation Committee to make annual equity awards at the beginning of the relevant performance cycle with the benefit of reviewing results from the immediately preceding performance cycle. We also may make equity awards at other times during the year for new hires or for other reasons, including, for example, a job promotion, as a result of an acquisition or for retention purposes. In accordance with our policy and our Omnibus Incentive Plan, the Compensation Committee has delegated limited authority to our CEO to approve grants to non-executive officers. Such awards may only be made on the first business day of a month. The Compensation Committee must approve any equity awards to our named executive officers.

We do not backdate or retroactively grant restricted stock units. We generally schedule Board and Compensation Committee meetings at least one year in advance and, as noted above, generally make annual equity awards to our executive officers at approximately the same time each year. We do not time our equity awards to take advantage of the release of earnings or other major announcements by us or market conditions.

Executive stock ownership

Our executive officers must own shares of our Common Stock in an amount equal to a multiple of their base salary. Stock ownership aligns management's interests with those of our shareholders and provides a continuing incentive for management to focus on long-term growth.

Under our executive stock ownership guidelines, our CEO must own shares worth six times his base salary and the other executive officers must own shares worth three times their base salaries. Executive officers who become subject to the guidelines have five years from the date of hire or change in status, whichever is later, to comply with the ownership requirements, but must retain all options and equity grants until required ownership

levels are met. Our stock ownership guidelines take into account directly held shares of our Common Stock, shares owned through our Employee Stock Purchase Plan, 2/3 of vested, in-the-money stock options, and outstanding restricted stock units. Following its annual review, the Compensation Committee determined that each of the named executive officers is in compliance with the guidelines.

We have a policy against the hedging and pledging of our securities that is applicable to our employees (including executive officers) and non-employee directors. See page 36 for more information.

Tax considerations

When setting executive compensation, we consider many factors, such as attracting and retaining executives and providing appropriate performance incentives. We also consider the after-tax cost to the Company in establishing executive compensation programs, both individually and in the aggregate, but tax deductibility is not our sole consideration. Section 162(m) of the Code generally disallows a federal income tax deduction to public companies for annual compensation over $1 million (per individual) paid to their chief executive officer, chief financial officer and the next three most highly compensated executive officers (as well as certain other officers who were covered employees in years after 2016). As a result, most of the compensation payable to our named executive officers in excess of $1 million per person in a year will not be fully deductible.

(1) ***Stock Awards and Option Awards.*** The amounts reported as stock awards and option awards represent the grant date fair values of equity awards shown in accordance with Accounting Standards Codification ("ASC") Topic 718, disregarding the estimate of forfeitures related to service-based vesting conditions. Such values do not reflect whether the recipient has actually realized a financial benefit from the award. There were no forfeitures by named executive officers in fiscal 2020, 2021 or 2022. See Note 10 to the Consolidated Financial Statements contained in our Annual Report on Form 10-K for the fiscal year ended September 30, 2022, relating to assumptions made in the valuations.

For awards that are subject to performance conditions, we report the fair values at grant date based upon the probable outcome of such conditions consistent with our estimate of aggregate compensation cost to be recognized over the service period determined under ASC Topic 718, excluding the effect of estimated forfeitures. For this purpose, the probable outcome is assumed to be at target level attainment and the grant date fair values of the fiscal 2022 — fiscal 2024 performance shares were as follows:

All long-term equity incentive awards were made pursuant to our Omnibus Incentive Plan. In accordance with the dividend rate applicable to the declaration of dividends on our Common Stock from time to time, dividends on unvested restricted stock units and unvested performance shares are accrued and paid upon vesting and, with regard to performance shares, the attainment of the required performance. The dividend rate is not preferential. There are no dividends paid on outstanding units or shares prior to vesting and, with regard to performance shares, without attainment of the required performance. See the sections of this proxy statement titled "Compensation discussion and analysis — Fiscal 2022 executive compensation program — Long-term equity incentives" for additional information regarding the fiscal 2022 equity awards and "Potential payments upon termination of employment or change in control" for a description of the impact of termination of employment on vesting and exercisability of equity awards.

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; These amounts represent possible payouts of fiscal 2022 cash bonuses under the AIP. The amounts shown in the "Threshold" column represent the minimum amount payable under the AIP based on the assumption that corporate and business unit performance met the thresholds established for the financial performance goals. We generally do not pay a bonus for performance that is below the threshold established for financial performance goals and we pay a bonus of 25% of the target amount for performance that is at the threshold established for financial performance goals. For performance that exceeds threshold but does not meet target, bonus payments are based on the level of performance and are increased ratably until target is reached. Actual payouts for fiscal 2022 are shown in the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; These share amounts represent the possible performance share award payouts under the Omnibus Incentive Plan at various levels of attainment for the performance period beginning October 1, 2021 and ending September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Amounts in this column represent the grant date fair value of restricted stock units, and performance shares. For awards made to our named executive officers on November 10, 2021, the dollar value shown for restricted stock units is based on the closing price of our Common Stock of $125.68 per share on November 10, 2021. For awards that are subject to performance conditions, such as the performance shares, in the table above, we report the value at grant date based upon the probable outcome of such conditions consistent with our estimate of aggregate compensation cost to be recognized over the service period determined under Accounting Standards Codification Topic 718, excluding the effect of estimated forfeitures. For this purpose, the probable outcome of the performance shares is assumed to be at target level attainment.

&nbsp;&nbsp;&nbsp;&nbsp;(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The following amounts represent executive contributions to the Deferred Compensation Plan that were previously reported as compensation in the Summary Compensation Table for fiscal 2022 and previous fiscal years, commencing with fiscal 2007: Mr. Collis: $2,569,842; Mr. Mauch: $277,740 and Ms. Clark: $151,020. The following amounts represent Company contributions to the Benefit Restoration Plan that were previously reported as compensation in the Summary Compensation Table for fiscal 2022 and previous fiscal years, commencing with fiscal 2007: Mr. Collis: $1,331,249; Mr. Cleary: $211,126; Mr. Mauch: $282,107, Ms. Clark: $148,481, and Ms. Battaglia: $46,332.

#### Deferred compensation plan
Eligible executive officers may elect to defer up to 50% of their annual cash compensation and have the deferred amount credited to an account under the deferred compensation plan. Deferral elections are made in December for compensation to be earned in the next year. Election forms must be filed for each year an executive officer wishes to defer compensation, and each form shall specify the method of payment of benefits and the time such payment is to commence. Participants select the notional investment options under the plan, which are the same as those under the Company's 401(k) plan, and may change their election at any time by contacting the plan administrator. The deferred benefits will be distributed in accordance with the terms of the plan, and payment will be made at the times elected by the executive officer in accordance with the election form. An executive officer must specify whether he or she wishes to receive payment starting in the year of retirement or in the year after retirement and may elect to receive the deferred benefits (i) over annual periods ranging from three to fifteen years and payable in quarterly installments or (ii) in a single distribution. We pay all costs and expenses incurred in the administration of the plan.

#### AmerisourceBergen Corporation benefit restoration plan
Selected key management, including all of the named executive officers, participate in the AmerisourceBergen Benefit Restoration Plan (the "Benefit Restoration Plan"). The Benefit Restoration Plan credits the account of each eligible participant with an annual amount equal to four percent (4%) of the participant's base salary and bonus incentive to the extent that his or her compensation exceeds the annual compensation limit established for our 401(k) plan by the Code. The compensation limit was $305,000 for calendar year 2022. Annual accruals under the Benefit Restoration Plan commenced effective as of January 1, 2006. In addition to annual accruals, certain eligible participants were credited upon the plan's effective date of January 1, 2006, with an initial amount based on his or her service between the time of the merger that formed AmerisourceBergen in 2001 and the plan's implementation. Fidelity Investments administers the Benefit Restoration Plan. Participants are permitted to allocate the amounts in their accounts among notional investment options specified by the Benefit Restoration Plan administrator from time to time. Such allocation is for the purposes of determining gains and losses based on the performance of the underlying notional investments. Account balances under the Benefit Restoration Plan begin to vest in part at age 55, but do not vest in full until an employee reaches age 62 or age 55 with more than 15 years of service, except that vesting is accelerated for disability, death and a change in control, provided the participant is employed by the Company on the date of the applicable event. If a participant is terminated for cause, he or she forfeits all vested and unvested account balances under the Benefit Restoration Plan.

## Potential payments upon termination of employment or change in control

#### Termination of employment without cause or resignation with good reason
Our named executive officers' employment agreements provide for severance payments in the event that we terminate their employment without cause or they leave the Company with good reason. Treatment of equity awards upon termination of employment or a change in control is described below under "Equity Awards." The table below identifies what would constitute cause or good reason to terminate employment under the agreements:

---

| | |
|:---|:---|
| **Cause for termination means:**  | **Good reason for termination means:**  |
| &nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Continued failure to substantially perform job duties (other than due to illness or injury) <br>| &nbsp;&nbsp;&nbsp; • Reduction in base salary <br>|

Executive compensation and related matters

In order to receive the severance payments upon termination without cause or with good reason as set forth in the employment agreement, the named executive officer must sign a customary release of any and all claims relating to the executive officer's employment with us. Severance payments and benefits include:

---

| | |
|:---|:---|
| Base Salary | &nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Payment of base salary for a period of two years following the termination of employment. <br>|
| Bonus | &nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Payment of a bonus for the year of termination, which, for named executive officers other than Mr. Collis, is based on actual performance, and for Mr. Collis is based on target performance, in each case prorated for the period of employment before the termination of employment.<br>• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; In the case of Mr. Collis, payment of an amount equal to two times the average annual bonuses paid in the preceding three completed years, to be paid in two annual equal installments. <br>|
| Benefits | &nbsp;&nbsp;&nbsp; • &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Reimbursement of costs incurred by the executive officer to continue health coverage for 18 months after the termination of employment.<br>• Executive outplacement assistance. <br>• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Vesting of any outstanding equity awards to the extent the terms governing such equity awards provide for accelerated or continued vesting.<br>|

---

Additionally, the executive officer is entitled to accrued but unpaid cash compensation, such as unpaid base salary, vacation pay, business expenses, any bonus for the prior fiscal year that has not been paid prior to the termination of employment, and any vested benefits accrued and due under the Company's benefit plans (the "Accrued Obligations"), regardless of whether the executive officer signs or revokes a release.

To the extent compliance with Section 409A of the Code is necessary to avoid the application of an excise tax to any of the foregoing payments and benefits, the employment agreements provide for deferral (without interest) of any affected amounts due in the six months following the termination of employment.

#### Termination of employment with cause or resignation without good reason
If we terminate an executive officer's employment for cause or the executive officer resigns without good reason, we will not pay the executive officer any severance benefits under the employment agreements. We will, however, pay the executive officer the Accrued Obligations. In addition, certain of the executive's outstanding equity awards will continue to vest if the voluntary termination in on account of retirement, as described in the table entitled "Potential payments upon termination of employment or change in control."

#### Disability or death
If an executive officer becomes disabled or dies, we will pay the executive officer, or the executive officer's estate, the executive officer's Accrued Obligations. In addition, any account balances under the Benefit Restoration Plan would vest upon the executive officer's total and permanent disability or death, and certain outstanding equity awards will continue to vest or vesting will be accelerated, as applicable. The value of the outstanding awards that would continue to vest or be accelerated, as applicable, as of September 30, 2022, is set forth in the table entitled "Potential payments upon termination of employment or change in control."

#### Change in control
The Company provides severance benefits under the employment agreements in connection with a change in control only in the event of a qualifying termination of employment without cause or with good reason within 24 months following the change in control (i.e., a "double trigger"). We do not provide cash severance or enhanced benefits under the employment agreements with our named executive officers solely in connection with a change in control of the Company. Account balances under the Benefit Restoration Plan will immediately vest upon a change in control as long as the executive officer remains employed by us on the date of the change in control. Equity awards will vest in connection with a termination of employment by us following a change in control, as summarized below under "Equity awards."

Executive compensation and related matters

Further, the Compensation Committee has discretion under our AIP to pay bonuses to eligible executive officers during any year in which a change in control occurs. If this discretion is exercised, bonus payments would be based on performance for the portion of the fiscal year through the change in control event and paid within 75 days of the change in control.

If payments and benefits otherwise payable to the executive officer in connection with a change in control would constitute excess parachute payments within the meaning of Section 280G of the Code, the Company will reduce such payments and benefits to an amount that would avoid any excise taxes under Section 4999 of the Code, but only if such reduction would provide the executive officer with a greater net after-tax benefit than would no reduction.

Except for the employment agreement with Mr. Collis, under the executive officer employment agreements, if an executive officer's employment is terminated by the Company without cause or the executive officer terminates employment with the Company with good reason, in either case upon or within two years following a change in control, the executive officer is entitled to increased severance, in addition to the amount described above under "Termination of employment without cause or resignation with good reason," in the form of a cash amount equal to two times the executive officer's average annual bonus earned over the prior three years, paid over a period of two years following termination of employment.

In the case of Mr. Collis, upon a termination without cause or with good reason within two years following a change in control, in lieu of the continued base salary and annual bonus payments described above under "Termination of employment without cause or resignation with good reason," Mr. Collis will be entitled to continued base salary for three years following termination of employment and three times the average annual bonus paid to Mr. Collis for the preceding three years, paid over a three-year period following termination of employment.

#### Retirement benefits and deferred compensation
Following retirement or other termination of employment, our named executive officers will receive payment of retirement benefits and deferred compensation under the various plans in which they participate. The value of the deferred compensation as of September 30, 2022, is set forth in the table entitled "Executive compensation and related matters — Nonqualified defined contribution and other deferred compensation in fiscal 2022." Certain of the executive's outstanding equity awards would continue to vest if the executive retires after meeting the retirement criteria of the award and retired. The value of the outstanding awards that would continue to vest upon retirement as of September 30, 2022, for those named executive officers who have met the retirement criteria is set forth in the table entitled "Potential payments upon termination of employment or change in control." There are no special or enhanced benefits under our retirement plans and deferred compensation plans for our named executive officers except in the event of an executive officer's disability or death or as a result of a change in control as described above.

#### Recoupment and clawback
Our named executive officers' employment agreements and their compensation payable thereunder are subject to the Incentive Compensation Restriction and Financial Recoupment Program of our Corporate Integrity Agreement and any applicable clawback or recoupment policies implemented by the Board or otherwise required by law. Our Compensation Recoupment Policy is summarized under "Executive compensation governance" in the Compensation Discussion and Analysis section on page 60.

#### Potential payments upon termination of employment or change in control
The table below quantifies the potential payments and the benefits that would continue to vest or be accelerated, as applicable, at, following, or in connection with the various scenarios described below, as if the termination of employment or change in control of the Company had occurred on September 30, 2022:

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Cash severance benefits under employment agreements entered into in the future would be subject to the limits under our new Policy Limiting Executive Severance, as described further on page 59.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The benefits shown in column (b) include the continued vesting of unvested equity that would apply under each grant's retirement provisions, with respect to each named executive officer who met the eligibility requirements for retirement as of September 30, 2022. Under the Company's Omnibus Incentive Plan, effective as of March 6, 2014, retirement is defined as any voluntary termination of employment (i) after reaching age 62 and completing 60 full months of continuous employment with us or (ii) after reaching age 55, where the sum of age and years of continuous employment with us equals at least 70. Messrs. Collis, Cleary and Mauch and Ms. Clark are currently eligible for retirement under their outstanding equity awards. Upon retirement, restricted stock units and options continue to vest to the extent and according to the schedule set forth in the applicable award agreement, and performance shares will vest based on actual performance as if the participant had continued in service through the applicable vesting date.

&nbsp;&nbsp;&nbsp;&nbsp;(3) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; If the named executive officer's employment is terminated by us other than for cause or by the executive officer with good reason, other than upon or within two years following a change in control, the named executive officer is entitled to two years of continued base salary. Mr. Collis also receives an amount equal to two times the average annual bonuses paid in the preceding three completed years, to be paid over two years. The named executive officers receive payment of a bonus for the year of termination, which, for the named executive officers other than Mr. Collis, is based on actual performance (assuming 100% attainment of the individual performance objectives), and for Mr. Collis is based on target performance, in each case prorated for the period of employment before the termination of employment. The named executive officers receive reimbursement of costs incurred by the named executive officer to continue health coverage for 18 months after termination of employment, and outplacement assistance. The named executive officers also receive continued equity vesting as described in footnotes (5), (6), and (7) below. The amounts shown in column (c) represent these total severance amounts.

&nbsp;&nbsp;&nbsp;&nbsp;(4) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For our named executive officers other than Mr. Collis, if the executive officer's employment is terminated by us other than for cause or by the executive officer with good reason upon or within two years following a change in control, the executive officer is entitled to two years of continued base salary and a bonus payment equal to two times the executive officer's average annual bonuses earned over the prior three completed years, to be paid over two years. In the event Mr. Collis' employment is terminated by us other than for cause or by Mr. Collis with good reason upon or within two years of change in control, Mr. Collis is entitled to three years of continued base salary, and a bonus payment equal to three times the average of the annual bonuses earned by Mr. Collis over the three completed years prior to the termination date, to be paid over three years. The named executive officers receive payment of a bonus for the year of termination, which, for the named executive officers other than Mr. Collis, is based on actual performance, and for Mr. Collis is based on target performance, in each case prorated for the period of employment before the termination of employment. The named executive officers receive reimbursement of costs incurred by the named executive officer to continue health coverage for 18 months after the termination of employment and outplacement assistance. The named executive officers also receive equity vesting as described in footnotes (5), (6) and (7) below. The amounts shown in column (f) represent these total severance amounts. The benefits shown in column (f) are in addition to any benefits that the named executive officer would receive as a result of the accelerated vesting of account balances under the Benefit Restoration Plan upon a change in control, as shown in column (e).

&nbsp;&nbsp;&nbsp;&nbsp;(5) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The value of the continued or accelerated vesting of unvested performance shares is calculated by multiplying the number of unvested performance shares that would vest at target by $135.33, the closing price of our Common Stock on September 30, 2022. Provided the named executive officer has been employed for at least 18 months from the grant date, a pro-rata portion of the unvested performance shares vest upon death or disability (based on performance through the end of the quarter prior to the death or disability). Provided the named executive officer has been employed for at least 18 months from the grant date and subject to

Executive compensation and related matters

execution and non-revocation of a release, a pro-rata portion of the unvested performance shares vest (based on actual performance) in the event of termination of employment by us without cause (other than within two years following a change in control of the Company). In the event of retirement during a performance period, unvested performance shares will vest based on actual performance. In the event of termination of employment by us, upon or within two years following a change in control, the unvested performance shares will vest based on performance through the end of the calendar quarter ending prior to the change in control. In accordance with SEC rules, equity awards that vested as of September 30, 2022, including performance shares for the fiscal 2020 — fiscal 2022 performance period, are not reflected in the table above. The remaining unvested performance shares that would continue to vest or accelerate vesting for each scenario are included at target performance.

(6) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The value of the continued or accelerated vesting of unvested restricted stock units is calculated by multiplying the number of shares of unvested restricted stock units held by the named executive officer as of September 30, 2022, by $135.33, the closing price of our Common Stock on that date. Unvested restricted stock units vest immediately in the case of disability, death, or upon an involuntary termination of employment by us, upon or within two years of a change in control of the Company. Unvested restricted stock units remain outstanding and continue to vest in the event of retirement.

(7) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The value of the continued or accelerated vesting of unvested options is calculated by multiplying the number of unvested options held by the named executive officer on September 30, 2022, by the difference between the exercise price of the options and $135.33, the closing price of a share of our Common Stock on that date. Unvested stock options vest upon termination of employment by us within two years following a change in control of the Company. Unvested stock options continue to vest and become exercisable in the event of retirement.

(8) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The amounts shown represent the value of unvested account balances under the Benefit Restoration Plan for events that would result in the accelerated vesting and payment of those benefits. Account balances under the Benefit Restoration Plan do not vest in full until an employee reaches age 62 (or age 55 with more than 15 years of service), except that vesting is accelerated upon (i) disability, (ii) death, or (iii) upon a change in control of the Company (so long as the participant is employed by the Company on the date of the applicable event). Unvested account balances are forfeited if the participant's employment terminates for any reason other than death, disability, or following a change in control before the applicable retirement date. If a participant is terminated for cause, the participant forfeits all vested and unvested account balances under the Benefit Restoration Plan. Distribution of account balances upon termination of employment, death, disability or change in control are made in a lump sum.

#### Equity Awards
Our restricted stock unit, performance share and stock option awards include provisions that result in the vesting or forfeiture of awards, depending on the reason for termination of employment, which provisions are outlined below.

In addition, in the event of a change in control, the Board may, in its discretion, cancel outstanding options that are not exercised within 30 days of the change in control, cash out the value of outstanding options or restricted stock units or make any other adjustments it deems appropriate under the Omnibus Incentive Plan. The Board may also cancel any award made under the Omnibus Incentive Plan in exchange for payment of an equal value in cash or stock.

## CEO pay ratio
As required by the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, the Company is required to calculate and disclose the ratio of the total compensation paid to its CEO to the total compensation paid to the median employee.

Using a Consistently Applied Compensation Measure ("CACM"), as described further below, we determined that the annual total compensation of our median employee of those employed as of July 1, 2022, other than the CEO and certain non-U.S. employees, was $68,343. Our CEO's total compensation, as described further below, was $16,747,382. Therefore, the ratio of our CEO's total annual compensation to that of the median paid employee was 245:1.

Our CACM was applied as follows:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; As of July 1, 2022, we determined that our total population consisted of 43,838 employees (excluding the CEO).

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We again used annual base pay as CACM to identify the median employee in fiscal 2022, which resulted in a new median employee.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; We excluded 2,085 team members from the countries identified below. The excluded team members represent the Company's entire employee population in each such country and account for less than 5% of the Company's total employee population.

---

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; After identifying the median employee based on annual base pay, we calculated total annual compensation for that employee and for the CEO using the same methodology we use for our named executive officers as set forth in the Summary Compensation Table in this proxy statement, plus the value of employer contributions to group medical, dental, life, and disability coverage to both the CEO and the median employee, as such benefits represent a significant portion of our employees' total compensation.

Because the SEC rules for identifying the median employee and calculating the pay ratio permit companies to use various methodologies, assumptions, exemptions, and estimates, the pay ratios reported by other companies may not be comparable with the ratio we have provided. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K.

## Item 4 — Advisory vote on the frequency of a shareholder vote on the compensation of our named executive officers
In accordance with Section 14A of the Exchange Act, our Board is asking you to vote on a proposal, commonly known as a "say-on-frequency" proposal, which gives our shareholders the opportunity to advise our Board on how often we should conduct an advisory shareholder vote on the compensation of our named executive officers. We are required to seek an advisory shareholder vote on the frequency of future "say-on-pay" proposals at least once every six years, although we may seek shareholder input more frequently. Shareholders are not voting to approve or disapprove the Board's recommendation. Instead, you may cast your vote on your preferred voting frequency by choosing any of the following four options with respect to this proposal:

• Every year;

• Every 2 years;

• Every 3 years; or

• Abstain.

For the reasons discussed below, the Board recommends a vote for a frequency of "every year" as set forth in the following resolution:

"**Resolved**, that a non-binding, advisory vote of AmerisourceBergen's shareholders to approve the compensation of AmerisourceBergen's named executive officers, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission (which disclosure includes the Compensation Discussion and Analysis, the Executive Compensation Tables and any related material) shall be held at an annual meeting of shareholders, beginning with the 2024 Annual Meeting of Shareholders, every year.

Because your vote is advisory, it will not be binding upon the Board. However, our Board values the opinions that our shareholders express in their votes and will take into account the outcome of the advisory vote when considering how frequently we should conduct an advisory vote on the compensation of our named executive officers.

Our Board believes that an annual advisory vote on the compensation of our named executive officers is an important aspect of shareholder engagement. An annual "say-on-pay" vote provides shareholders the opportunity to evaluate our compensation policies and procedures on a regular basis. Specifically, because the Company makes its compensation decisions on an annual basis, we believe our shareholders should have an annual opportunity to provide advisory approval of these decisions. We also believe that an annual frequency vote provides the highest level of accountability and direct communication with our shareholders.

Based on our shareholders' strong support in our prior "say-on-frequency" advisory vote in 2017, our Board believes that a majority of our shareholders prefer an annual vote. Since the advisory vote in 2017, we have conducted "say-on-pay" votes every year. In accordance with Section 14A of the Exchange Act, the next "say-on-frequency" vote will be held at our 2029 Annual Meeting of Shareholders.

## Prohibition of loans to directors and officers
Our corporate governance principles prohibit us from making any loans or extensions of credit to directors or executive officers. We do not have any programs under which we extend loans to either directors or officers.

## Related persons transactions policy
We have a written Related Persons Transactions Policy, which is posted on our website at investor.amerisourcebergen.com/governance/policies/default.aspx. The Audit Committee must approve or ratify any transaction, arrangement or relationship exceeding $120,000 in which the Company and any related person has a direct or indirect material interest. This policy includes any series of transactions that exceeds $120,000 in the aggregate in any calendar year. Related persons include:

• directors and director nominees;

• executive officers;

• persons controlling more than 5% of our Common Stock;

• the immediate family members of each of these individuals; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; a firm, corporation or other entity in which any of these individuals is employed or is a partner or principal or in which any of these individuals has more than 5% ownership interest.

Related persons must notify our Executive Vice President and Chief Legal Officer in advance of any proposed transaction with us. They must explain the principal features of the proposed transaction, including its potential value and benefit to us. Our Executive Vice President and Chief Legal Officer will refer all proposed related person transactions exceeding $120,000 to the Audit Committee for review.

The Audit Committee will consider the proposed transaction at its next regularly scheduled meeting. In reviewing the proposed transaction, the committee will take into account those factors it considers appropriate, including the business reasons for the transaction and whether the terms of the transaction are fair to the Company and no less favorable than would be provided by an unaffiliated third party. The committee will also consider, if applicable, whether the proposed transaction would impair the independence of a director or present an improper conflict of interest for directors, director nominees or executive officers. Directors with an interest in any proposed transaction will not vote on the proposed transaction. The Audit Committee will review annually any ongoing or continuous related person transactions.

## Related persons transactions
Walgreens Boots Alliance, through Walgreens Boots Alliance Holdings LLC (formerly known as WAB Holdings LLC), controls more than 5% of our Common Stock, and transactions between us and Walgreens Boots Alliance are subject to our Related Persons Transactions Policy. In fiscal 2022, transactions between the Company and Walgreens Boots Alliance accounted for approximately 27% of our revenues and 38% of our receivables. For fiscal 2022, revenue from various agreements and arrangements with Walgreen Boots Alliance was $64.1 billion, and the Company's receivable, net of incentives, was $7.0 billion.

As previously disclosed, in March 2013, we established a strategic relationship with Walgreens Boots Alliance. As part of that strategic relationship, we entered into various agreements and arrangements with Walgreens Boots Alliance and certain of its affiliates, including a ten-year pharmaceutical distribution agreement, pursuant to which we distribute branded and generic pharmaceutical products to Walgreens Boots Alliance (the "US PVA"), and a generics purchasing services arrangement that provides us with the ability to access generics and related pharmaceutical products through a global sourcing arrangement with Walgreens Boots Alliance Development GmbH (the "WBAD Arrangement").

We also entered into a Shareholders Agreement with Walgreens Boots Alliance in March 2013 (the "Shareholders Agreement"). The Shareholders Agreement contains, among other things, certain restrictions on

Related person transactions

Walgreens Boots Alliance's ability to transfer its shares of our Common Stock. The Shareholders Agreement also contains certain standstill provisions that, among other things and subject to certain exceptions, prohibit Walgreens Boots Alliance from acquiring additional shares of our Common Stock. The standstill provisions prohibit Walgreens Boots Alliance from entering into voting agreements or granting a proxy to any other person; participating or engaging in a proxy solicitation with respect to AmerisourceBergen; seeking to control or influence the management or policies of AmerisourceBergen; or entering into or proposing a merger, business combination or other similar extraordinary transaction involving AmerisourceBergen. The foregoing restrictions do not prohibit Walgreens Boots Alliance from, subject to certain requirements, making private proposals to AmerisourceBergen subject to the approval of our Board, or competing with third-party acquisition proposals. The Shareholders Agreement also contains various provisions relating to Board representation, voting arrangements, registration rights and other matters. The subsidiaries of Walgreens Boots Alliance that hold our Common Stock (including Walgreens Boots Alliance Holdings) are also subject to the above-mentioned restrictions and provisions.

Under the Shareholders Agreement, Walgreens Boots Alliance became entitled to designate a director to our Board when it, together with its subsidiaries, achieved ownership of 5% or more of our Common Stock. Ornella Barra is currently serving on our Board as Walgreens Boots Alliance's designee and is a nominee for re-election as a director. Ms. Barra has served as a director of the Company since January 2015 and is a member of our Compliance & Risk Committee and Finance Committee.

Walgreens Boots Alliance is entitled to designate a second director to our Board if, together with its subsidiaries, it acquires in one or more open market transactions, a total of 19,859,795 shares of our Common Stock (subject to certain adjustments). If Walgreens Boots Alliance divests its equity securities such that it owns less than 5% of the Common Stock, Walgreens Boots Alliance will no longer be entitled to designate any directors to the Board, and the Shareholders Agreement will, subject to certain exceptions, terminate.

For so long as Walgreens Boots Alliance has the right to designate a director to our Board, subject to certain exceptions, including matters related to acquisition proposals, Walgreens Boots Alliance will be obligated to vote all of its shares of our Common Stock in accordance with the recommendation of the Board on all matters submitted to a vote of our shareholders (including the election of directors).

As previously disclosed, in June 2021, we acquired a majority of Walgreens Boots Alliance's Alliance Healthcare businesses for $6.275 billion in cash, subject to certain purchase price adjustments, and 2 million shares of our Common Stock.

We also extended the US PVA and the WBAD Arrangement by three years through 2029 and entered into a distribution agreement pursuant to which we will supply branded and generic pharmaceutical products to WBA's Boots pharmacies in the United Kingdom through 2031.

We also entered into an Amended and Restated Shareholders Agreement, which amended and restated in its entirety the Shareholders Agreement and, among other things, increased by 1% the percentage of outstanding shares of our Common Stock which Walgreens Boots Alliance and its affiliates are permitted to hold.

## Item 5 — Shareholder ratification of termination pay
The following shareholder proposal has been submitted to the Company for action at the 2023 Annual Meeting by Kenneth Steiner, 14 Stoner Avenue, 2M, Great Neck, New York 11021. Mr. Steiner has named John Chevedden as his proxy for this proposal. In accordance with proxy regulations, the following is the complete text of the proposal, which is reproduced as submitted to us other than minor formatting changes. All statements contained in the shareholder proposal and supporting statement are the sole responsibility of the proponent.

#### Proposal 5 — Shareholder Ratification of Termination Pay
![[MISSING IMAGE: tm2227032d1-ban_shrrig4c.jpg]](tm2227032d1-ban_shrrig4c.jpg)

Shareholders request that the Board seek shareholder approval of any senior manager's new or renewed pay package that provides for severance or termination payments with an estimated value exceeding 2.99 times the sum of the executive's base salary plus target short-term bonus.

"Severance or termination payments" include cash, equity or other pay that is paid out or vests due to a senior executive's termination for any reason. Payments include those provided under employment agreements, severance plans, and change-in-control clauses in long-term equity plans, but not life insurance, pension benefits, or deferred pay earned and vested prior to termination.

"Estimated total value" includes: lump-sum payments; payments offsetting tax liabilities, perquisites or benefits not vested under a plan generally available to management employees, post-employment consulting fees or office expense and equity awards if vesting is accelerated, or a performance condition waived, due to termination.

The Board shall retain the option to seek shareholder approval after material terms are agreed upon.

Generous performance-based pay can sometimes be justified but shareholder ratification of "golden parachute" severance packages with a total cost exceeding 2.99 times base salary plus target short-term bonus better aligns management pay with shareholder interests.

For instance at one company, that does not have this policy, if the CEO is terminated he could receive $44 million in termination pay — over 10 times his base salary plus short-term bonus. In the event of a change in control, the same person could receive a whopping $124 million in accelerated equity payouts even if he remained employed.

Shareholder proposal

The proposal is more important at AmerisourceBergen due to the information in this article:

#### 'Deeply problematic': AmerisourceBergen rewards its CEO despite the ravages of the opioid crisis
In one of the more startling examples of tin-ear syndrome, AmerisourceBergen wants its shareholders to bless a $14.3 million pay package for chief executive officer Steven Collis. Not only is this a hefty amount of money, but it represents a 26% boost over the previous year.

The pharmaceutical wholesaler can act so generously thanks to a tricky maneuver: excluding the cost of legal settlements for evaluating executives. For those not tracking the sprawling opioid litigation around the U.S., ABC is expected to pay $6.6 billion to compensate communities for the cost of grappling with substance use disorder, prescription drug overdoses, and deaths.

By manipulating numbers this way, ABC turned a $3.4 billion loss in 2020 — its biggest ever — into an adjusted profit of $1.6 billion. And Mr. Collis qualified for nearly $10.3 million in cash and stock he would not have received otherwise, according to Michael Pryce-Jones, corporate governance analyst at the International Brotherhood of Teamsters, which holds stock in ABC.

Shareholder Ratification of Termination Pay — Proposal 5

#### AmerisourceBergen Corporation's statement in opposition to the shareholder proposal

|:---|:---|
| ![[MISSING IMAGE: tm2227032d1-icon_worngpn.gif]](tm2227032d1-icon_worngpn.gif)  | The Board of Directors recommends that you vote **AGAINST** Proposal No. 5 (Item 5 on the proxy card) for the following reasons: |

---

Proposal No. 5 requests that AmerisourceBergen seek shareholder approval of any senior manager's new or renewed pay package that provides for severance or termination payments with an estimated value exceeding 2.99 times the sum of the executive's base salary plus target short-term bonus (the "2.99 Limit"). The Board believes that the shareholder proposal is unnecessary and not in the best interests of shareholders, based on the reasons listed below.

The Board's primary rationale for its recommendation is its approval of the AmerisourceBergen Corporation Policy Limiting Executive Severance (the "Severance Policy"), effective November 9, 2022. Specifically, under the Severance Policy, cash severance payments to executive officers made after the effective date must be less than 2.99 times base salary plus target annual bonus.

The Board also believes that the shareholder proposal is inappropriate and unnecessary for the following reasons:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The proposal discourages the use of at-risk, long-term equity incentive awards, which are tied to maximizing long-term shareholder value and delivering significant performance results.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The proposal would unduly restrict the Compensation Committee's ability to structure compensation programs.

• Our compensation programs already effectively align our executive officers' and shareholders' interests.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The proposal could place the Company at a competitive disadvantage by limiting our ability to attract and retain highly qualified and effective employees.

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The proposal would create expensive and impractical obstacles by requiring the Company to call a special meeting of shareholders in order to negotiate a severance arrangement.

#### The Company's Severance Policy already limits cash severance payments for executive officers to less than 2.99 times base salary plus target annual bonus.
Following conversations with shareholders, our Board recently adopted the Severance Policy, which provides that the Company will not enter into any new employment agreement, severance agreement, or similar arrangement with any of our executive officers, or establish any new severance plan or policy covering any of

Shareholder proposal

our executive officers, that, in each case, provides for cash severance benefits exceeding 2.99 times the sum of the executive officer's base salary plus target bonus, without first seeking shareholder approval of such agreement, plan, policy, or arrangement.

The Board believes that the Severance Policy is more carefully tailored to the Company's needs and the interests of shareholders than the broad policy provided for in the proposal and strikes the right balance between shareholder rights and the Company's ability to remain competitive in the market for talent. Specifically, the Severance Policy includes the following features: (i) it applies to involuntary terminations of employment (as opposed to termination "for any reason," as contemplated by the proposal); (ii) allows certain exclusions to the types of compensation subject to the policy, such as payments of salary or bonus amounts that had accrued at the time of termination; and (iii) applies to a clearly defined group of the Company's executive officers (as opposed to "any senior manager," an undefined and potentially very broad population of employees, as contemplated by the proposal). As a result, the Severance Policy enables the Company to offer certain post-termination benefits in situations that we believe are appropriate, such as permitting equity vesting in the event of an executive officer's death or disability or upon an involuntary termination of employment within two years of a change in control of the Company. These are scenarios where we believe acceleration of equity vesting is appropriate and should not be subject to specific shareholder approval beyond the general say-on-pay advisory vote that we hold annually.

Additionally, the Severance Policy applies to a clearly defined group of individuals designated by the Board as "officers" under Rule 16a-1(f) of the Exchange Act. The Board believes that this is an appropriate group, as these are the individuals charged with the policy-making decisions that ultimately impact operational results and, by extension, shareholder value. The policy provided for in the proposal, however, refers to "senior managers" without providing any definition of this term. We are a global company with approximately 43,000 employees and potentially hundreds of managers that could be deemed "senior managers." The proposal, as drafted, could be interpreted to apply to a very large number of employees. The lack of definition regarding precisely which senior managers' severance compensatory arrangements are implicated leaves the Company without a clear understanding of the circumstances under which a severance arrangement would be subject to the 2.99 Limit and require shareholder approval before adoption.

Accordingly, the policy requested by the proposal would represent a significant broadening of the existing Severance Policy, which we believe is appropriately constructed and administratively feasible, as well as introduce uncertainty as to the specific population covered and compensation included. Please see the section entitled "Severance and change in control benefits" on page 59 for more information regarding the Severance Policy.

#### The proposal discourages the use of at-risk, long-term equity incentive awards, which are tied to maximizing long-term shareholder value and delivering significant performance results.
The policy provided for in the proposal could require shareholder approval in order for certain employees and executive officers to realize the full value of their equity awards upon a qualifying termination related to a change in control or in the event of an executive officer's death or disability. Since calling a special meeting of shareholders to obtain shareholder approval of such accelerated vesting would be expensive and impractical, the Board believes that the proposal would have the practical effect of discouraging the use of long-term equity incentive awards and, accordingly, directly conflict with the objectives of our executive compensation programs — namely, the alignment of shareholder and executive officer interests. In addition, because the value of future equity awards is uncertain at the time that an employment agreement is entered into, the Company would face additional uncertainty around situations to which the proposed policy applies.

We believe long-term performance is a critical measure of our success, as we manage the Company's operations and business for the long-term benefit of our shareholders. Equity incentives in the form of performance shares and restricted stock units support the achievement of our business strategies and goals, align financial rewards with the economic interests of our shareholders, facilitate significant stock ownership by our executive officers, and promote retention of the leadership talent that is critical to our success. These awards are a fundamental element of our compensation programs and are granted to and accepted by employees with the expectation that they will be given a fair opportunity to realize the full value of these awards if the Company performs well against its strategic goals.

Shareholder proposal

#### The proposal would unduly restrict the Compensation Committee's ability to structure compensation programs.
We believe that the Compensation Committee is best positioned to oversee the design and structure of our compensation program to address our needs as a global company. Our employees are located in numerous jurisdictions and their compensatory arrangements are subject to, and greatly influenced by, numerous laws, rules, and regulations of different foreign and U.S. federal and state jurisdictions in which our operations are based. The Compensation Committee needs to have the flexibility and discretion to approve effective compensation programs, after considering factors such as regulatory complexity across jurisdictions, market competitiveness, and the Company's strategic, operational, and financial goals. Imposing the 2.99 Limit or otherwise requiring shareholder approval would unduly limit the Compensation Committee's ability to exercise its judgment.

#### Our compensation programs already effectively align our executive officers' and shareholders' interests.
The Company's executive compensation program is strongly focused on pay-for-performance principles. We emphasize a compensation philosophy that rewards our executive officers when they deliver targeted results and subjects a significant portion of their compensation to risk if they do not. The compensation of our executive officers varies depending upon the achievement of pre-established performance goals. Through stock ownership requirements and equity incentives, we also align the interests of our executive officers with those of our shareholders and the long-term interests of the Company. Additionally, because of our pay-for-performance philosophy, our executive compensation program is designed not only to attract and retain highly qualified and effective employees, but also to motivate them to substantially contribute to the Company's future success for the long-term benefit of shareholders and reward them for doing so.

Furthermore, the equity-based awards that comprise our long-term incentive compensation represent the largest percentage of our executive officers' targeted total direct compensation, which has the practical effect of aligning their interests with the interests of our shareholders. All equity compensation awards to our executive officers are made under incentive compensation plans approved by our shareholders, including most recently the Company's Omnibus Incentive Plan, which was approved by approximately 90% of the votes cast at our 2022 Annual Meeting of Shareholders. Furthermore, our shareholders have indicated significant support for our executive compensation programs, evidenced by the fact that the Company's say-on-pay approval rating exceeded 95% at last year's annual meeting.

#### The proposal could place the Company at a competitive disadvantage by limiting our ability to attract and retain highly qualified and effective employees.
Because we operate a global enterprise in a highly challenging business environment, we compete for talented employees with some of the largest companies in the world — in both our industry and others. Our global recognition makes our employees attractive targets for other companies, and our key employees are aggressively recruited. To prevent loss of our talent at all levels of the organization, we seek to provide an overall compensation program that is competitive with all types of companies and continues to attract and retain outstanding leaders to run our business. Each element of compensation, including severance provisions for key employees, is intended to fulfill this important objective.

The Company relies on equity awards and carefully designed severance programs to motivate and retain our employees, and we believe that these awards and programs are necessary for us to remain competitive in attracting and retaining highly qualified individuals upon whom, in large measure, the future growth and success of the Company depends. The proposed policy could severely disadvantage our ability to recruit qualified employees, especially given the potential breadth of "senior manager" employees the proposal appears to cover. Top candidates, when informed that the terms of their compensation arrangements first require shareholder approval, likely would be unwilling to wait for such approval and may instead seek employment elsewhere, including at one of the Company's competitors that do not have similar restrictions on their ability to offer severance benefits.

**The proposal would create expensive and impractical obstacles by requiring the Company to call a special meeting of shareholders in order to negotiate a severance arrangement.** 

A requirement to call a special meeting of shareholders to obtain prior approval of a severance arrangement that would provide benefits in excess of the 2.99 Limit would be expensive and impractical. Avoiding

[**TABLE OF CONTENTS**](#TOC2)

Shareholder proposal

shareholder approval by entering into severance arrangements for amounts less than the 2.99 Limit would not offer a practical solution to this obstacle.

The benefits covered by the 2.99 Limit in the proposal include not only cash severance but also the value of prior equity awards that are accelerated upon a severance event. It is market practice and invariably the case, particularly with regard to highly sought-after employees, that employment agreements or other severance arrangements provide for at least partial vesting of equity awards upon certain types of severance events, which we have limited to certain circumstances (i.e., double-trigger change in control scenarios, death, and disability). An arrangement that provides for accelerated vesting of stock awards upon severance, even if permitted only on a partial, pro-rata basis, would have a higher probability of exceeding the 2.99 Limit. We believe that shareholder interests are best served by voting against the proposal so that we can continue to grant equity-based pay with multi-year vesting requirements and remain competitive in attracting and retaining highly qualified employees.

#### Conclusion
The Board believes that our current executive compensation policies and practices, including our plans and policies governing post-termination compensation, are reasonable, appropriate, and effectively align the interests of our executive officers with those of our shareholders. Adoption of the policy requested by the proposal could create a misalignment between those interests and prevent us from effectively recruiting and retaining critical talent, and therefore would not be in the best interests of our shareholders.

#### What does it mean if I receive more than one proxy card or instruction form?

We recommend that you consolidate as many accounts as possible under the same name and address. For assistance consolidating accounts where you are the shareholder of record, you may contact our transfer agent, Computershare, at 1-800-522-6645.

#### Will my shares be voted if I do not provide my proxy?
If you are a registered shareholder and do not provide a proxy, in order to vote your shares, you must do so over the Internet or by telephone prior to the meeting or by virtually attending the 2023 Annual Meeting of Shareholders and voting online during the meeting.

If a beneficial owner of shares does not provide the bank or broker holding such shares with specific voting instructions, under the rules of the NYSE, the shareholder's bank or broker may generally vote on "routine" matters, but cannot vote on "non-routine" matters. "Broker non-votes" occur when a beneficial owner of shares held in street name fails to provide instructions to the broker, bank, or other holder of record as to how to vote on matters deemed non-routine. Proposal 1 (election of directors), Proposal 3 (say-on-pay advisory vote), Proposal 4 (say-on-frequency advisory vote), and Proposal 5 (Shareholder Proposal) are non-routine matters. Proposal 2 (ratification of auditor) is a routine matter. If a shareholder's bank or broker does not receive the shareholder's instructions on how to vote the shareholder's shares on a non-routine matter, the shareholder's bank or broker will inform the Company it does not have the beneficial owner's authority to vote on the non-routine matter. In these cases, the broker, bank, or other holder of record can register your shares as being present at the 2023 Annual Meeting of Shareholders for purposes of determining the presence of a quorum, but will not be able to vote on those matters for which specific authorization is required under the NYSE rules. We encourage beneficial shareholders to provide voting instructions to the bank, broker, or agent holding their shares by carefully following the instructions in the notice provided by the shareholder's bank, broker, or agent.

#### May shareholders ask questions at the meeting?
Yes. If you wish to submit a question, you may do so in two ways. To ask a question in advance of the 2023 Annual Meeting of Shareholders, you may log into www.proxyvote.com and enter your 16-digit control number and use the Submit a Question for Management box. Alternatively, you will be able to submit questions live during the 2023 Annual Meeting of Shareholders through the Q&A box by accessing the meeting website at www.virtualshareholdermeeting.com/ABC2023 if you have entered the meeting website as an authenticated shareholder using your 16-digit control number. After the formal business of the 2023 Annual Meeting of Shareholders has concluded and adjourned, the chair of the 2023 Annual Meeting of Shareholders will answer questions from shareholders during the designated question and answer ("Q&A") period of the 2023 Annual Meeting of Shareholders agenda.

In order to give as many shareholders as possible the opportunity to ask questions, we ask that questions are succinct and cover only one topic per question. Up to three minutes will be allocated to read and respond to each question that we are able to answer during the 2023 Annual Meeting of Shareholders. The Q&A session will continue until all relevant questions have been answered, subject to time constraints.

Shareholders' views, constructive comments, and criticisms are welcome, but the Company will not address questions that do not conform with the 2023 Annual Meeting Rules of Conduct, including but not limited to questions that are irrelevant to the business of the Company or to the business of the 2023 Annual Meeting of Shareholders, in furtherance of a shareholder's personal or business interests, which are not matters of interest to shareholders generally, or out of order or not otherwise suitable for the conduct of the 2023 Annual Meeting of Shareholders. The Rules of Conduct may be found by accessing the meeting website at www.virtualshareholdermeeting.com/ABC2023.

If there are any matters of individual concern to a shareholder or questions that are not answered, they may be raised separately after the 2023 Annual Meeting of Shareholders by contacting Investor Relations at InvestorRelations@amerisourcebergen.com.

#### How many votes must be present to hold the meeting?
In order for us to conduct our meeting, a majority of the shares of our Common Stock outstanding as of January 9, 2023 must be present in order to constitute a quorum. Your shares are counted as present at the meeting if you virtually attend the meeting or if you properly return a proxy over the Internet, by telephone or by mail. Shares voted by banks or brokers on behalf of beneficial owners are also counted as present at the meeting. In addition, abstentions and broker non-votes will be counted for purposes of establishing a quorum with respect to any matter properly brought before the meeting.

#### How many votes are needed to elect a director and how are votes counted?
 *The affirmative vote of a majority of the votes cast will be required for the election of each director (Item 1 on the proxy card).* 

A majority of the votes cast means that the votes cast "for" a director exceed the number of votes cast "against" that director. Abstentions and broker non-votes are disregarded when determining if a majority of the votes have been cast in favor of a director.

#### How many votes are needed for Items 2 through 5 to pass and how are the votes counted?
The Company is incorporated in the State of Delaware and our shares are listed on the New York Stock Exchange ("NYSE"). As a result, the Delaware General Corporation Law ("DGCL") and NYSE listing standards govern the voting standards applicable to actions taken by our shareholders.

Under our bylaws, the affirmative vote of the holders of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote on the matter are required to approve Items 2, 3, 4 and 5 set forth on the proxy card.

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Under the DGCL, shares that abstain with respect to Items 2, 3, 4 and 5 constitute shares that are present and entitled to vote and, accordingly, have the practical effect of being voted "against" such items.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Under NYSE rules, Item 2 is considered a "routine" proposal on which brokers are permitted to vote in their discretion even if the beneficial owners do not provide voting instructions. However, Items 3 through 5 are not considered to be routine matters and brokers will not be entitled to vote thereon unless beneficial owners provide voting instructions. Accordingly, broker non-votes will not be counted toward the tabulation of votes on Items 3, 4, and 5.

#### How will proxies be voted on other items or matters that properly come before the meeting?
If any other items or matters properly come before the meeting, the proxies received will be voted on those items or matters in accordance with the discretion of the proxy holders.

#### Is AmerisourceBergen aware of any other items of business that will be presented at the meeting?
We are not aware of any other business to be presented at the 2023 Annual Meeting of Shareholders. However, if any other matter should properly come before the 2023 Annual Meeting of Shareholders, the accompanying proxy confers discretionary authority with respect to such matter.

#### Will there be any further solicitation of proxies for the meeting?
Our directors, officers and employees may solicit proxies by telephone, text message, email, facsimile or in person. In addition, we have hired Morrow Sodali ("Morrow"), 333 Ludlow St, 5th Floor, South Tower, Stamford, CT 06902 to assist us in soliciting proxies, if necessary. Morrow may solicit proxies by telephone, text message, email, facsimile or in person. We will pay Morrow a fee of $12,000, plus expenses, for providing such services. We reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable expenses incurred by them in sending proxy materials to their customers or principals who are the beneficial owners of shares of our Common Stock. All costs and expenses of any solicitation, including the cost of preparing this proxy statement and posting it on the Internet and mailing the Notice of Internet Availability of Proxy Materials, will be borne by AmerisourceBergen.

#### Will the director nominees be in attendance at the meeting?
We currently expect all of our director nominees to virtually attend the 2023 Annual Meeting of Shareholders and all directors are expected to attend our annual meetings pursuant to our governance principles. All of our directors attended the 2022 Annual Meeting of Shareholders.

Shareholder proposals must comply with SEC Rule 14a-8, Delaware law and our bylaws. Failure to deliver a proposal by these means may result in it not being deemed timely received.

#### Other shareholder proposals for presentation at the 2024 annual meeting of shareholders
Shareholders of record who do not submit a proposal for inclusion in AmerisourceBergen's proxy materials under SEC Rule 14a-8, but who instead intend to nominate a person for election as director or to introduce an item of business at the 2024 Annual Meeting of Shareholders must provide advance written notice to us in accordance with our bylaws. Our bylaws set forth the procedures that must be followed and the information that must be provided in order for a shareholder to nominate a person for election as director or to introduce an item of business at the 2024 Annual Meeting of Shareholders. We must receive notice of your intention to introduce a nomination or other item of business at the 2024 Annual Meeting of Shareholders no earlier than November 10, 2023 and no later than December 10, 2023. Such notice should be addressed to Corporate Secretary, AmerisourceBergen Corporation, 1 West First Avenue, Conshohocken, PA 19428, and must include the information set forth in our bylaws. You may obtain a copy of our bylaws upon request by writing to the Secretary at our principal executive offices. The proxy solicited by our Board for the 2024 Annual Meeting of Shareholders will confer discretionary authority with respect to any such proposal.

The chair of the 2024 Annual Meeting of Shareholders may refuse to allow the transaction of any business or acknowledge the nomination of any person not made in compliance with the procedures set forth for such matters in our bylaws.

#### Proxy access shareholder proposals for the 2024 Annual Meeting of Shareholders
Eligible shareholders who do not seek to use the advance notice provisions for nomination of directors in Section 2.03(c) of our bylaws, but who instead intend to nominate a person for election as director under the proxy access provision in our bylaws must comply with the provisions of and provide notice to us in accordance with Section 3.16 of our bylaws. That Section sets forth the shareholder eligibility requirements and other procedures that must be followed and the information that must be provided to us in order for an eligible shareholder to have included in our proxy materials for the 2024 Annual Meeting of Shareholders up to two nominees for election as director at the Annual Meeting of Shareholders. We must receive the required notice and information specified in Section 3.16 no earlier than August 30, 2023 and no later than September 29, 2023.

The proxy solicited by our Board of Directors for the 2024 Annual Meeting of Shareholders will confer discretionary authority with respect to any such nomination.

In addition, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company's director nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than January 9, 2024.

#### Other shareholder communications with the Board
Interested parties may communicate with the Board by submitting at any time in writing to: Corporate Secretary, AmerisourceBergen Corporation, 1 West First Avenue, Conshohocken, PA 19428. These communications may be from an interested party to the Board, any committee or any director on matters that relate reasonably to their respective duties and responsibilities. Such communications do not include shareholder proposals (discussed above) and shareholder recommendations for director nominee candidates (discussed under "Corporate governance and related matters — Shareholder recommendations for director nominees"). AmerisourceBergen's Secretary will determine, in his good faith judgment, which communications will be relayed to the Board, any committee or any director.

#### Householding
As permitted by the rules of the SEC, we have adopted the procedure of "householding" whereby we deliver a single set of proxy materials to one address shared by two or more of our shareholders. This procedure can result in significant cost savings. We have delivered only one set of proxy materials to multiple shareholders who share an address, unless we received contrary instructions from the impacted shareholders prior to the mailing date. We will promptly deliver, upon written or oral request, a separate copy of the proxy materials to any shareholder at the shared address to which a single copy of these documents was delivered.

## Appendix A

## Supplemental information: GAAP to non-GAAP reconciliation
To supplement the financial measures prepared in accordance with U.S. generally accepted accounting principles (GAAP), we have presented the following non-GAAP financial measures elsewhere in this proxy statement:

(i) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; adjusted operating income;

(ii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; adjusted diluted earnings per share; and

(iii) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; adjusted free cash flow.

The non-GAAP financial measures should be viewed in addition to, and not in lieu of, financial measures calculated in accordance with GAAP. These supplemental measures may vary from, and may not be comparable to, similarly titled measures by other companies.

The following is a reconciliation of the identified GAAP financial measures to their most directly comparable non-GAAP financial measures:

---

|:---|:---|:---|
| | **Fiscal year ended September 30, 2022**  | **Fiscal year ended September 30, 2022**  |
| **(in thousands, except per share data)**  | **Operating income<br>($)**  | **Diluted earnings per share<br>($)**  |
| GAAP | 2366378 | 8.04 |
| Gains from antitrust litigation settlements | (1835) | (0.01) |
| Turkey highly inflationary impact | 40033 | 0.25 |
| LIFO expense | 67171 | 0.25 |
| Acquisition-related intangibles amortization | 304551 | 1.10 |
| Litigation and opioid-related expenses | 123191 | 0.47 |
| Acquisition, integration, and restructuring expenses | 183059 | 0.70 |
| Gain on remeasurement of equity investment |  | (0.02) |
| Goodwill impairment | 75936 | 0.14 |
| Impairment of assets | 4946 | 0.02 |
| Gain on sale of non-core businesses |  | (0.20) |
| Certain discrete tax benefits |  | 0.08 |
| Tax reform<sup>(1)</sup> |  | 0.22 |
| Adjusted non-GAAP | 3163430 | 11.03(2) |

&nbsp;&nbsp;&nbsp;&nbsp;(1) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Includes tax expense relating to Swiss tax reform and a loss on the currency remeasurement of the related deferred tax assets, the latter of which is recorded within Other Income, Net in our Consolidated Statement of Operations.

&nbsp;&nbsp;&nbsp;&nbsp;(2) &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; The sum of the components does not equal the total due to rounding.

In addition, for the fiscal year ended September 30, 2022, adjusted free cash flow of $2,977.8 million consisted of net cash provided by operating activities of $2,703.1 million, minus capital expenditures of $496.3 million and the gains from antitrust litigation settlements of $1.8 million, plus legal settlement payments of $772.9 million.

The non-GAAP financial measures are presented because management uses non-GAAP financial measures to:

• evaluate the Company's operating performance,

• perform financial planning, and

• determine incentive compensation.

Therefore, the Company believes that the presentation of non-GAAP financial measures provides useful supplementary information to, and facilitates additional analysis by, investors. The presented non-GAAP

Appendix A

financial measures exclude items that management does not believe reflect the Company's core operating performance because such items are outside the control of the Company or are inherently unusual, non-operating, unpredictable, non-recurring, or non-cash. We have included the following non-GAAP earnings-related financial measures in this proxy statement:

#### Adjusted operating income
Adjusted operating income is a non-GAAP financial measure that excludes:

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; gains from antitrust litigation settlements;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Turkey highly inflationary impact;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LIFO expense;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acquisition-related intangibles amortization;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; litigation and opioid-related expenses;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acquisition, integration and restructuring expenses;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; goodwill impairment; and

• impairment of assets.

Acquisition-related intangibles amortization is excluded because it is a non-cash item and does not reflect the operating performance of the acquired companies. We exclude acquisition, integration, and restructuring expenses that are unpredictable and/or non-recurring. We exclude the amount of litigation settlements and other expenses, such as goodwill impairment and the impairment of assets, that are unusual, non-operating, unpredictable, non-recurring or non-cash in nature because we believe these exclusions facilitate the analysis of our ongoing operational performance.

#### Adjusted diluted earnings per share
Adjusted diluted earnings per share excludes (in each case net of the tax effect calculated using the applicable effective tax rate for those items):

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; the per share impact of adjustments, including gains from antitrust litigation settlements;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Turkey highly inflationary impact;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; LIFO expense;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acquisition-related intangibles amortization;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; litigation and opioid-related expenses;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; acquisition, integration and restructuring expenses;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; gain on remeasurement of equity investment;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; gain/loss on sale of non-core businesses;

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; goodwill impairment; and

• &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; impairment of assets.

In addition, the per share impact of certain benefits and expenses relating to tax reforms in Switzerland and the UK are excluded from adjusted diluted earnings per share. Management believes that this non-GAAP financial measure is useful to investors because it eliminates the per share impact of the items that are outside the control of the Company or that we consider to not be indicative of our ongoing operating performance due to their inherent unusual, non-operating, unpredictable, non-recurring, or non-cash nature.

#### Adjusted free cash flow
Adjusted free cash flow is a non-GAAP financial measure defined as net cash provided by operating activities, excluding significant unpredictable or non-recurring cash payments or receipts relating to legal settlements, minus capital expenditures. Adjusted free cash flow is used internally by management for measuring operating cash flow generation and setting performance targets and has historically been used as one of the means of providing guidance on possible future cash flows.
