| **Circular Economy** | **Solutions** |
| We believe that the packaging industry must move beyond the make/use/dispose behaviors of the past and actively work toward, and advocate for, a circular economy. By circulating used plastic and packaging, we keep it in the economy and out of the environment.<br>Collaboration is essential to achieving a more circular economy, so we engage with partners, suppliers and customers who share our vision.<br>Aptar is an active member of the World Business Council for Sustainable Development (WBCSD) and the Ellen MacArthur Foundation's Circular Economy 100 (CE100) Network. Through the Ellen MacArthur Foundation, we have also signed the New Plastics Economy Global Commitment to address plastic waste and pollution at its source. | Our product sustainability strategy addresses recyclability and reusability, resin conversion and sustainable design. Much of this work is aligned with that of our partners. We offer a range of products made from post-consumer resin ("PCR"). We are committed to seeking additional opportunities for more sustainable resins and recyclability of our products.<br>We are actively working to identify new materials, such as PCR, that can be approved and used for food contact. This is in part why we have partnered with PureCycle Technologies, a leading innovator in the field of Ultra-Pure Recycled Polypropylene (UPRP), and NextLoopp, an organization focused on providing a circular pathway for PCR materials. We continue to explore opportunities to source other sustainable resins and we are actively collaborating with our customers on refillable products by supporting our customers' participation in circular e-commerce platforms such as TerraCycle's refillable initiative called "Loop." |

| &nbsp;&nbsp;We continue to take steps to make our operations more energy efficient and reduce our impact on the environment.<br>We are proud of our grass-roots initiative to certify our operating sites as **"landfill free"** ("LFF"). Our internal LFF Program was one of our first established operational sustainability programs and was developed based on the Zero Waste International Alliance (ZWIA) protocol. This program recognizes sites that reuse or recycle over 90% of their operational wastes. We use an independent third party to audit the waste management processes in each location and to verify the certification.<br>At year-end 2022, 65% of Aptar facilities had achieved LFF certification and, globally, Aptar avoided sending more than 80% of operational wastes to landfill. We have LFF certified sites in Europe, North America, Latin America and Asia.  | &nbsp;&nbsp;We continue to take steps to make our operations more energy efficient and reduce our impact on the environment.<br>We are proud of our grass-roots initiative to certify our operating sites as **"landfill free"** ("LFF").

We have LFF certified sites in Europe, North America, Latin America and Asia.  | &nbsp;&nbsp;We are committed to Science-Based Targets and to sourcing 100% of our electricity from renewable sources by 2030.<br>In 2020, we formalized our science-based targets, setting a Scope 1 and Scope 2 emissions reduction goal consistent with requirements to keep global warming well below 2° Celsius by year 2030, and a Scope 3 reduction goal consistent with requirements to keep global warming at 2° Celsius by year 2030. We surpassed our original Scope 1 and Scope 2 reduction target within the first year of validation by the Science Based Targets Initiative ("SBTi"). Therefore, in 2022 we began working with SBTi to revise the Scope 1 and Scope 2 target to a more aggressive ambition, and to align it to the requirements to keep global warming at 1.5° Celsius by 2030. This revised target was officially validated by SBTi in March 2023.<br>Aptar's Scope 3 ambition remains the same, as does our commitment to increase annual sourcing of renewable electricity to 100% by 2030. **At year-end 2022 we were sourcing more than 95% of our electricity from renewable sources.** <br>Compared to our 2019 baseline, Aptar has made progress cutting emissions, and continues efforts to mitigate climate risks and further the low-carbon economy, as reported by the Company through global environmental non-profit CDP's 2022 climate change and water questionnaires. We believe Aptar is leading on corporate environmental ambition, action and transparency worldwide as proven by our inclusion on the CDP Supplier Engagement Leaderboard for the third consecutive year. |

### Supporting our Communities

---

| | |
|:---|:---|
| Aptar has partnered with CARE®, a 501(c) organization that works around the globe to save lives, defeat poverty and achieve social justice. CARE's mission aligns with our purpose, values and mission to further diversity and inclusion, to empower women and to support the communities where we live and work, along with global communities that are the most marginalized and the most in need. | ![Graphic](atr-20230503xdef14a_a064.jpg) |

---

Through our ongoing global partnership, Aptar will support CARE's mission, including education programming, women's economic empowerment efforts and CARE's Crisis Response Campaign, sponsoring the Fast + Fair COVID-19 Vaccine Response Campaign and the Ukraine Crisis Fund.

Our Charitable Foundation in the United States continues to recognize the importance of giving back to local communities. Through a Corporate Grant Program and an Employee Matching Gift Program, the Foundation supports eligible 501(c)(3) organizations in our communities with a focus on the health and human services, culture and the arts.

We also give back to communities outside the United States. We support the Vatsalya Foundation, which is a pioneer agency working with street children in Mumbai, India through its multilevel approach of outreach, child-to-child contact, contact centers and a shelter home. Our leadership team often visits the foundation and the children are often invited to visit our local offices for a day filled with fun activities such as a hand painting competition, traditional games and more.

### Responsible Workplaces
A safe working environment for our employees is a top priority. That is why we implemented a global environmental, health and safety ("EHS") management system. The Aptar EHS management system includes a digital platform to report incidents as well as track corrective actions. Aptar's EHS management system includes an Ergonomics program and Behavior Based Safety (BBS) program, which promotes a culture of caring through accountability to self and to the team. At year-end 2022, we reduced the Total Recordable Incident Rate ("TRIR") by 6% and Lost Time Frequency Rate ("LTFR") by 7% from year end 2021. We outperformed the TRIR average in our industry, and we are closing in on a LTFR that also surpasses our industry average.

We are also a proud member of Sedex, one of the world's leading ethical trade service providers, striving to improve working conditions in global supply chains. Sedex provides for a global platform to report on labor standards and health and safety practices in order to share that information with key stakeholders, including our customers. All of our manufacturing sites have completed site-level social assessments through the Sedex platform every year since 2020.

## Proposal 1: Election of Directors
The Board of Directors is currently comprised of 11 members divided into three classes, with one class of directors elected each year for a three year term. The Board of Directors proposes the following nominees, all of whom are currently serving as directors, to be elected to a term expiring at the 2026 annual meeting. The Corporate Governance Committee engaged the executive search firm Egon Zehnder International for the purpose of identifying highly qualified director nominee candidates that also support our philosophy on diversity summarized below. As a result of this engagement, Julie Xing was referred to the Corporate Governance Committee for evaluation and consideration, was appointed to the Board in March 2023 and is standing for election for the first time at the annual meeting.

If any of the director nominees is unable or fails to stand for election, the persons named in the proxy intend to vote for a substitute nominee nominated by the Corporate Governance Committee of the Board of Directors.

We believe all of the members of the Board of Directors are individuals of outstanding character and sound judgment that have the business experience and acumen necessary to work together effectively and to make valuable contributions to the Board of Directors and management. As a U.S.-based company with significant international operations, particularly in Europe, we seek to maintain a balanced Board consisting of directors that are U.S. citizens and directors that are citizens from countries other than the U.S. Additionally, we value the following attributes: operating experience in packaging or packaging-related businesses; skill sets which may include experience in finance, strategic planning, marketing, pharmaceutical products and manufacturing; diversity, including a mix of genders and multi-cultural viewpoints; and previous board of directors experience.

Set forth below is biographical and other background information concerning each director nominee and each continuing director. This information includes each person's principal occupation as well as a discussion of the specific experience, qualifications, attributes and skills of each person that led to the Board of Directors' conclusion that he or she should continue to serve as a director. In addition, set forth below is the year during which each person began serving on the Board of Directors and his or her age.

Under the stock ownership guidelines, directors must achieve the required level of ownership within five years from becoming a director. As of March 10, 2023, the record date, every non-employee director (including the Chairman of the Board) is either in compliance with the guidelines or within the five-year phase-in period.

### Board and Committee Structure
The Chairman of the Board is an independent director who is not an executive officer or employee of the Company. The Company believes that having an independent Chairman enhances the oversight ability of the Board. An independent Chairman can also provide stability and continuity during senior management transitions.

Under the corporate governance requirements of the NYSE listing standards, if an audit committee member simultaneously serves on the audit committee of more than three public companies, the board must determine that such simultaneous service would not impair the ability of such member to effectively serve on the listed company's audit committee. The Board has determined that the service of Ms. Montiel on the audit committee of more than three public companies does not impair her ability to serve effectively as a member of our Audit Committee.

#### Risk Assessment of Cybersecurity Threats to Operations
Increased global cybersecurity threats and more sophisticated, targeted computer crime could pose a risk to our operations. Aptar places great importance on information security, including cybersecurity, to protect against external threats and malicious insiders. Our cybersecurity strategy prioritizes detection, analysis and response to known, anticipated or unexpected cyber threats, effective management of cyber risks and resilience against cyber incidents. We maintain an information security program consisting of organizational, operational, administrative, physical and technical safeguards appropriate to the scope and nature of our business. We continue to assess potential threats and make investments seeking to reduce the risk of these threats by implementing a broad set of security measures, including comprehensive monitoring of our networks and systems, rapid detection, response and threat management capabilities and ensuring strong data protection standards are in place to safeguard our critical information assets.

Security and Data Privacy awareness and training is provided at least annually for Aptar employees, which is designed to help employees recognize information security and cybersecurity concerns and respond

appropriately. Management briefs the Audit Committee on a quarterly basis regarding our information security programs. As part of its oversight responsibilities, the Audit Committee regularly discusses and reviews with management, among other items, Aptar's compliance and cybersecurity programs. We also periodically test our systems for vulnerabilities and regularly rely on third parties to conduct such tests. An independent review of our cybersecurity program has been assessed against the National Institute of Standards and Technology (NIST) cybersecurity framework. In addition, we maintain cybersecurity insurance as part of our overall insurance portfolio.

#### Risk Assessment of Compensation Policies and Practices
The Company has concluded that there are not any compensation policies or practices that are reasonably likely to have a material adverse effect on the Company. The Board concurred with this conclusion. In conducting its risk assessment related to compensation policies and practices, the Company considered, among other things: that the policies and practices do not offer the opportunity for excessive awards; the Company has reasonable stock ownership guidelines; the policies and practices are reviewed and approved by the Management Development and Compensation Committee; the Company has an established, robust control environment; and the Company conducts a regular monthly business review that monitors quality of reporting and prevents excessive risk taking.

No director qualifies as independent unless the Board affirmatively determines that the director has no material relationship with Aptar either directly or indirectly as a partner, stockholder or officer of an organization that has a relationship with Aptar. |

\* Current President and CEO

In addition, the Board determined that Mr. Jesse Wu, who served as a director during 2022, was independent. The Board has made its independence determination based on the following categorical standards, in addition to any other relevant facts and circumstances. These standards provide that a director generally will not be independent if:

● The director is or has been an employee of the Company within the last three years or has an immediate family member who is or has been an executive officer of the Company within the last three years.

● The director has received or an immediate family member has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the Company

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

other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).

● The director is, or has an immediate family member who is, a current partner of a firm that is the Company's internal or external auditor ("Firm").

● The director is a current employee of such Firm.

● The director has an immediate family member who is a current employee of such Firm and who personally works on the Company's audit.

● The director was, or has an immediate family member who was, within the last three years but is no longer a partner or employee of such Firm and personally worked on the Company's audit within that time.

● The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company's present executive officers at the same time serves or served on that company's compensation committee.

● The director is a current employee or an immediate family member is a current executive officer of another company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other company's consolidated gross revenues.

● The director or an immediate family member is, or has been within the last three years, a director or executive officer of another company that is indebted to the Company, or to which the Company is indebted, if the total amount of either company's indebtedness for borrowed money to the other is or was 2% or more of the other company's total consolidated assets.

● The director or an immediate family member is currently an officer, director or trustee of a charitable organization that in any of the last three fiscal years received from the Company, or any executive officer of the Company, annual charitable contributions to the organization that exceeded the greater of $1 million, or 2% of such charitable organization's gross revenue for the last completed fiscal year.

The Board considers the following to be immaterial when making independence determinations:

● If a director is an officer, director or trustee of a charitable organization or entity to which the Company has made grants or contributions in the past year of less than $100,000.

#### Executive Sessions
Independent directors meet regularly in executive sessions without management. The non-executive Chairman of the Board, Mr. Fotiades, presides over these sessions. An executive session is held in conjunction with each regularly scheduled Board meeting and other sessions may be held from time to time as required.

#### Nomination of Directors
In identifying and evaluating nominees for director, the Corporate Governance Committee takes into account the applicable requirements for directors under the Exchange Act, and the listing standards of the NYSE. The Corporate Governance Committee also takes into account the outside positions of the director nominees, together with their contributions to Aptar's Board and their other business and professional commitments, to ensure that each director had, and will have, sufficient capacity to serve on Aptar's Board.

The Board has established a maximum age limit for director nominees. Nominees must be 74 years old or younger at the time of election or re-election.

In addition to candidates recommended by members of the Board or management, the Corporate Governance Committee also considers individuals recommended by stockholders. The Corporate Governance Committee evaluates candidates recommended for director by stockholders in the same way that it evaluates any nominee recommended by members of the Board or management. In order to recommend a candidate, stockholders must submit the individual's name and qualifications in writing to the Corporate Governance Committee (in care of the Secretary at Aptar's principal executive offices at 265 Exchange Drive, Suite 301, Crystal Lake, Illinois 60014) and otherwise in accordance with all of the procedures outlined under "Other Matters—Stockholder Proposals and Nominations" for a director nomination.

The Corporate Governance Committee may engage outside advisers to identify potential director candidates from time to time. The effectiveness of the nomination process is evaluated by the Board each year as part of its annual self-evaluation and more formally by the Corporate Governance Committee as it evaluates and identifies director candidates.

#### Majority Voting Policy
Our amended and restated by-laws require majority voting for the election of directors in uncontested elections. This means that a director nominee in an uncontested election must receive a number of votes "FOR" that director's election that exceeds the number of votes cast "AGAINST" that director's election. Our Corporate Governance Principles further provide that any incumbent director who does not receive a majority of "FOR" votes will promptly tender to the Board his or her resignation from the Board. The Corporate Governance Committee will consider the tendered resignation and recommend to the Board whether to accept or reject the tendered resignation, or whether other action should be taken. The Board will consider the recommendation and publicly disclose its decision within 120 days after the annual meeting. The director who tenders his or her resignation will not participate in the recommendation of the Corporate Governance Committee or the decision of the Board with respect to his or her resignation.

#### Communications with the Board of Directors
The Board has established a process for stockholders and other interested parties to communicate with the Board or an individual director, including the non-executive Chairman or the independent directors as a group. A stockholder or other interested party may contact the Board or an individual director by writing to their attention at Aptar's principal executive offices at 265 Exchange Drive, Suite 301, Crystal Lake, Illinois 60014. Communications received in writing are distributed to the Board or to individual directors as appropriate in accordance with procedures approved by Aptar's independent directors.

BOARD MEETING ATTENDANCE

The Board met 6 times in 2022. During 2022, no current director attended fewer than 75% of the aggregate number of meetings of the Board held during such director's term and the committees on which each director then served. Aptar does not have a formal policy regarding director attendance at the annual meeting of stockholders. Messrs. Fotiades and Tanda attended the 2022 annual meeting.

attending Board and committee meetings. No retirement benefits or perquisites are provided to non-employee directors.

The non-employee director compensation program is designed to facilitate the continued attraction and retention of directors with the skills, expertise and experience valued by Aptar and position the total compensation for directors near the market median for the general industry survey data and Aptar's peer group used to evaluate executive compensation (described below under "Compensation Determination" in the "Compensation Discussion and Analysis" section).

## Proposal 2: Advisory Vote to Approve Executive Compensation
Pursuant to Section 14A of the Exchange Act, Aptar stockholders are being offered the opportunity to cast a non-binding advisory vote at the annual meeting to approve the compensation of Aptar's Named Executive Officers ("NEOs") as disclosed in the Compensation Discussion and Analysis ("CD&A") and tabular disclosures of this proxy statement. This is not a vote on the Company's general compensation policies or the compensation of the Board. We currently intend to submit an advisory vote on the compensation of our NEOs to our stockholders annually.

Aptar's compensation philosophy and objectives are to fairly reward our executives for growing our business and increasing value to stockholders and to retain our experienced management team.

The overall compensation program for NEOs includes an annual performance incentive element that rewards the NEOs for the Company's short-term performance and improvement in Company performance from the prior year, as well as equity-based elements (RSUs and long-term performance incentive awards in the form of performance-based RSUs, or PRSUs) that provide for long-term compensation that is driven by our share performance and, therefore, is aligned with our stockholders' interests. The specific objectives of our compensation program are that a substantial portion of the NEOs' compensation should be performance-based and should be delivered in the form of equity-based awards. Our CD&A describes our compensation philosophy and objectives in more detail.

The Board of Directors values the opinions of our stockholders. Although the resolution is advisory and non-binding, the Board will consider the outcome of the advisory vote when making future compensation decisions.

## Proposal 3: Advisory Vote on the Frequency of the Advisory Vote on Executive Compensation
Pursuant to Section 14A of the Exchange Act, Aptar stockholders are being offered the opportunity to cast a non-binding advisory vote at the annual meeting to approve the recommended frequency of future advisory votes to approve the compensation of our NEOs. The option of one year, two years or three years receiving the greatest number of votes will be considered the frequency recommended by the Company's stockholders.

Following the recommendation of our stockholders approved at the 2017 annual meeting of stockholders, we currently submit an advisory vote on the compensation of our NEOs to our stockholders annually. After careful consideration of the various arguments supporting each frequency level, the Board believes that continuing to submit the advisory vote on the compensation of our NEOs to stockholders on an annual basis is appropriate for Aptar and our stockholders at this time.

The Board of Directors values the opinions of our stockholders. Although the resolution is advisory and non-binding, the Board will consider the outcome of the advisory vote when determining the frequency of future advisory votes to approve the compensation of our NEOs.

## Proposal 4: Approval of an Amendment to the 2018 Equity Incentive Plan

#### Background
As of March 10, 2023, there were 706,658 shares of common stock that remained available for future issuances under the AptarGroup, Inc. 2018 Equity Incentive Plan ("2018 Plan") (assuming outstanding PRSUs are counted at target). Given the limited number of shares that currently remain available under the 2018 Plan, the Board and management believe it is important that the Plan Amendment—described below—be approved in order to maintain Aptar's ability to attract and retain key personnel, continue to provide them with strong incentives to contribute to Aptar's future success and to further align their interests with stockholder interests. The Board believes that Aptar has used equity in a reasonable manner under the 2018 Plan and its prior equity plans, with a three-year average burn rate of approximately 1.24% of Aptar's outstanding shares of common stock.

#### Proposed Amendment
On February 20, 2023, the Board approved an amendment to the 2018 Plan, subject to approval by Aptar's stockholders, that would increase the total remaining number of shares available for issuance under the amended 2018 Plan by 1,300,000 (the "Plan Amendment"). After adding the shares of common stock that remained available for future issuances under the 2018 Plan as of March 10, 2023—706,658 to the additional shares approved by the Plan Amendment—1,300,000, there will be a total of 2,006,658 shares available for future issuance under the 2018 Plan.

Under the terms of the amended 2018 Plan, the maximum number of shares of common stock authorized to be issued is 1,950,000 (representing an initial share authorization of 950,000 and an increase of 1,000,000 shares approved by our stockholders in 2020); however, if the Plan Amendment is approved, the maximum number of shares of common stock authorized to be issued under the 2018 Plan will increase from 1,950,000 to 3,250,000. If the Plan Amendment is not approved by Aptar's stockholders, Aptar will continue to operate the 2018 Plan pursuant to its current provisions. A copy of the 2018 Plan, as amended by the Plan Amendment, is attached as Appendix A to this proxy statement.

The following table sets forth information regarding outstanding options, full value awards and common shares outstanding as of March 10, 2023, for all Aptar equity award plans. These figures represent an update to those provided in our Form 10-K for the fiscal year ended December 31, 2022, filed on February 17, 2023, and in the section of this proxy statement entitled "Equity Compensation Plan Information." The outstanding options and full value awards disclosed below are not entitled to any dividends or dividend equivalents.(1)

&nbsp;&nbsp;&nbsp;&nbsp;(1) This table excludes March 2023 LTI awards.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Included in this column are 617,349 PRSUs (at target). Under the terms of the PRSU award agreements, the vesting level of the PRSUs may range from 0% to 200% based on Aptar's performance during the three-year performance period

*Importance of the Plan.* The Board believes that the 2018 Plan is an important part of Aptar's overall compensation program. The purpose of the 2018 Plan is to promote the long-term financial interests of Aptar and its affiliates by (i) attracting and retaining employees, non-employee directors, consultants, independent contractors, and agents; (ii) motivating award recipients by means of growth-related incentives; (iii) providing competitive incentive compensation opportunities; and (iv) further aligning the interests of award recipients with those of our stockholders.

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

The 2018 Plan incorporates the following features:

● It offers the ability to grant stock options, stock appreciation rights ("SARs"), restricted stock, and RSUs;

● It requires a minimum vesting or performance period of one year that is applicable to 95% of the shares subject to the 2018 Plan (however we have historically not issued awards with minimum vesting periods of less than one year), subject to accelerated vesting upon a change in control, termination of employment or service or as otherwise determined by the Committee;

● It prohibits repricing of awards, the issuance of stock options or SARs below fair market value, and the transfer of nonqualified stock options or SARs by a participant for consideration;

● It prohibits "liberal" share counting provisions, such as counting only the net number of shares issued upon exercise of a stock option or SAR, adding back shares withheld to satisfy taxes on any award or tendered to pay the exercise price of a stock option or SAR, and adding back shares repurchased by Aptar on the open market with the proceeds of an option exercise;

● It prohibits dividends or dividend equivalents to be paid with respect to options and SARs; and

● It prohibits the payment of dividends and dividend equivalents on a current basis with respect to restricted stock and RSUs—meaning that any dividends or dividend equivalents paid will be subject to the same vesting conditions as the underlying awards.

#### Description of the 2018 Plan
The 2018 Plan became effective on May 2, 2018 and will terminate on May 2, 2028 unless terminated sooner by the Board or Committee. A summary of the material features of the 2018 Plan is provided below. The summary is qualified in its entirety by, and made subject to, the complete text of the 2018 Plan (as amended by the Plan Amendment) attached as Appendix A to this proxy statement.

#### 2018 Plan Share Limits
The Plan Amendment would increase the total number of shares available for issuance under the 2018 Plan by 1,300,000, from 1,950,000 to 3,250,000 (reduced by the number of shares of common stock subject to awards granted under the AptarGroup, Inc. 2016 Equity Incentive Plan on or after March 9, 2018). All of the available shares under the 2018 Plan may be issued in connection with incentive stock options ("ISOs") under Section 422 of the Internal Revenue Code of 1986 (the "Code"). The number of shares of common stock that remain available for future grants under the 2018 Plan will be reduced by the sum of the aggregate number of shares of common stock which become subject to an outstanding award. Shares of common stock available under the 2018 Plan may be treasury shares reacquired by Aptar or authorized and unissued shares, or a combination of both.

Under the terms of the 2018 Plan, to the extent that shares of common stock subject to an outstanding award granted under either the 2018 Plan or any equity compensation plan previously maintained by Aptar on behalf of employees or non-employee directors (a "Prior Plan") are not issued or delivered by reason of (i) the expiration, termination, cancellation, or forfeiture of such award or (ii) the cash settlement of such award, then such shares of common stock will again be available under the 2018 Plan. The number of shares that again become available pursuant to this paragraph will be equal to one share for each share subject to an award described in this paragraph; provided, however, any shares from a Prior Plan that become available again under the 2018 Plan pursuant to this paragraph will be added to the available share reserve based on the share deduction ratio set forth in such Prior Plan.

The 2018 Plan prohibits "liberal share recycling"—meaning that shares of common stock will not again be available under the 2018 Plan (i) if tendered to satisfy all or a portion of tax withholding obligations relating to an award, (ii) if withheld to pay the exercise price of stock options or SARs awarded or (iii) if repurchased by Aptar on the open market with the proceeds of an option exercise.

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

#### Non-Employee Director Award Limit
The aggregate value of cash compensation and the grant date fair value of shares that may be awarded or granted during any fiscal year to any non-employee director may not exceed $500,000, provided that this value will be multiplied by two for awards granted to a non-employee director in the year in which he or she commences services on the Board.

#### Terms of the Plan
*Administration; Eligibility*. The 2018 Plan is administered by the Management Development & Compensation Committee. The 2018 Plan empowers the Management Development & Compensation Committee, among other things, to (i) select participants; (ii) make awards in such forms and amounts as the Committee will determine; (iii) impose limitations, restrictions and conditions upon awards as the Management Development & Compensation Committee deems appropriate; (iv) approve forms to carry out the purposes and provisions of the 2018 Plan; (v) interpret the 2018 Plan; (vi) adopt, amend, and rescind administrative guidelines and other rules and regulations relating to the 2018 Plan; (vii) correct any defect or omission or reconcile any inconsistency in the 2018 Plan or award granted under the 2018 Plan; and (viii) make all other determinations and take all other actions necessary or advisable for the implementation and administration of the 2018 Plan. The Management Development & Compensation Committee may, in its sole discretion and for any reason at any time, take action such that (i) any or all outstanding options and SARs will become exercisable in part or in full, (ii) all or a portion of the restriction period applicable to any outstanding awards will lapse, (iii) all or a portion of the performance period applicable to any outstanding awards will lapse and (iv) the performance goals (if any) applicable to any outstanding awards will be deemed to be satisfied at the target, maximum or any other interim level.

All grants of awards under the 2018 Plan are within the discretion of the Management Development & Compensation Committee. The Management Development & Compensation Committee does not have authority to reprice any stock option or SAR granted under the 2018 Plan without stockholder approval.

Under the terms of the 2018 Plan, participants in the 2018 Plan consist of such employees, non-employee directors, consultants, independent contractors and agents and persons expected to become employees, non-employee directors, consultants, independent contractors and agents of Aptar and its affiliates as the Management Development and Compensation Committee in its sole discretion may select from time to time. As of March 10, 2023, all Aptar employees (approximately 13,000 individuals) and non-employee directors (10 individuals) are eligible to participate in the 2018 Plan if selected by the Management Development and Compensation Committee.

*Minimum Vesting and Performance Period Requirements*. The 2018 Plan includes a minimum vesting and, if applicable, a minimum performance period of one year with respect to 95% of the shares subject to the 2018 Plan (however we have historically not issued awards with minimum vesting periods of less than one year). Vesting may accelerate upon a change in control, a termination of employment or service, including in the case of a termination without cause, constructive discharge, or termination of employment or service due to death, disability, or retirement, or as otherwise determined by the Management Development & Compensation Committee. The minimum vesting and performance period restrictions are not required with respect to the number of shares that does not exceed five percent of the total number of shares available for awards under the 2018 Plan.

*Options*. An option entitles the holder to receive upon exercise up to the maximum number of shares of common stock subject to the option at an option price that is fixed at the time the option is granted. Options may be either ISOs or other options, except that, as long as required by Section 422 of the Code, no ISO may be awarded to any employee of an Aptar affiliate that is not an Aptar "subsidiary corporation" (as such term is used in Section 422(b) of the Code) or any non-employee director, consultant, or independent contractor agent. The exercise price of an option may not be less than 100% of the fair market value of a share of common stock at the time the option is granted (or 110% in the case of an ISO granted to a holder of more than 10% of the common stock (a "10% Holder")), unless the option was an award granted upon the assumption of, or substitution for, an outstanding equity award previously granted by another company in connection with a corporate transaction (a "Substitute Award"), in which case the exercise price will instead be subject to other requirements under the 2018 Plan. Subject to the minimum vesting requirements in the 2018 Plan, an option will be exercisable at such time or times as the Management Development & Compensation Committee determines at the time of grant, provided that an option may not be exercised later

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

than 10 years after its date of grant (five years in the case of an ISO granted to a 10% Holder). The 2018 Plan allows optionees, to the extent permitted by the Management Development & Compensation Committee, to pay the exercise price of options in cash or common stock (valued at its fair market value on the date of exercise) or a combination of cash and common stock, with the proceeds from the sale of the shares purchased through an arrangement with a broker, or by authorizing Aptar to withhold whole shares that would otherwise be delivered upon the exercise of the option. No dividend equivalents will be paid on any options.

*SARs*. An SAR entitles the holder to receive upon exercise the excess of the fair market value of a specified number of shares of common stock at the time of exercise over a base price. Aptar will pay that amount to the holder in common stock (valued at its fair market value on the date of exercise), or to the extent provided for in an applicable award agreement, cash or a combination of cash and common stock, as the Management Development & Compensation Committee may determine. An SAR may be granted in tandem with a previously or contemporaneously granted option or independent of any option. The base price of an independent SAR will be fixed by the Management Development & Compensation Committee at not less than 100% of the fair market value of a share of common stock on the date of grant, unless the SAR is a Substitute Award, in which case the base price will instead be subject to other requirements under the 2018 Plan. An SAR granted in tandem with an option will entitle the optionee, in lieu of exercising the option, to receive (i) the excess of the fair market value of a share of common stock on the date of exercise over the option price multiplied by (ii) the number of shares as to which the optionee is exercising the SAR. If an SAR is granted in tandem with an option, the option will be cancelled to the extent the SAR is exercised, and the SAR will be cancelled to the extent the option is exercised. Subject to the minimum vesting requirements in the 2018 Plan, each SAR will be exercisable at such time or times as the Management Development & Compensation Committee determines at the time of grant, provided that an SAR may not be exercised later than 10 years after its date of grant. No dividend equivalents will be paid on any SAR.

*Restricted Stock*. Subject to the minimum vesting requirements in the 2018 Plan, the Management Development & Compensation Committee may grant restricted common stock with such restriction periods as the Management Development & Compensation Committee designates. A restricted stock award may be subject to other conditions of vesting, including performance goals, as the Management Development & Compensation Committee establishes. Except as otherwise provided in the 2018 Plan, the participant may not sell, assign, transfer, pledge, or otherwise encumber shares of restricted stock. Except for restrictions on transfer and other restrictions as the Management Development & Compensation Committee may impose, the participant will have all the rights of a holder of common stock as to restricted stock; provided that cash dividends payable on the common stock during the restriction period or the performance period, as the case may be, will be subject to the same restrictions as those on the shares of restricted stock.

*Restricted Stock Units*. Subject to the minimum vesting requirements in the 2018 Plan, the Management Development & Compensation Committee may award RSUs with such restriction periods as the Management Development & Compensation Committee designates. An RSU may be subject to other conditions to vesting, including performance goals, as the Management Development & Compensation Committee may establish. Each RSU represents the right to receive one share or, to the extent permitted in the applicable award agreement, the fair market value in cash of one share upon the expiration of the restriction period. A participant holding RSUs will not have the rights of a holder of common stock. Any dividend equivalents paid to a holder of an RSU will be subject to the same vesting conditions as the underlying award.

*Performance Goals.* Performance goals may include, but are not limited to, the corporate-wide or affiliate, business segment, division, operating unit, or individual measures set forth below. In its discretion, the Management Development & Compensation Committee may establish any other objective or subjective corporate-wide or affiliate, division, operating unit or individual measures as performance goals, whether or not listed in the 2018 Plan.

● Profitability Measures: (1) earnings per share; (2) earnings before interest and taxes ("EBIT"); (3) earnings before interest, taxes, depreciation and amortization ("EBITDA"); (4) business segment income; (5) net income; (6) operating income; (7) revenues; (8) profit margin; (9) cash flow(s); and (10) expense reduction;

● Capital Return Measures: (1) return on equity; (2) return on assets or net assets; (3) return on capital or invested capital; (4) EBIT to capital ratio; (5) EBITDA to capital ratio; (6) business segment income to business segment capital ratio; (7) working capital ratios; (8) total stockholder return; (9) increase in stockholder value; (10) attainment by a

share of common stock of a specified market value for a specified period of time; and (11) price-to-earnings growth; and

● Other Performance Measures: (1) successful implementation of strategic initiatives relating to cost reduction, revenue production, and/or productivity improvement; (2) successful integration of acquisitions; (3) market share; (4) economic value created; (5) market penetration; (6) customer acquisition; (7) business expansion; (8) customer satisfaction; (9) reductions in errors and omissions; (10) reductions in lost business; (11) management of employment practices and employee benefits; (12) supervision of litigation; (13) supervision of information technology; and (14) quality and quality audit scores.

*Deferral*. A participant may defer receipt of all or a portion of any award in accordance with procedures established by the Management Development & Compensation Committee and in accordance with Section 409A of the Code.

*Transferability*. Awards are not transferable other than (i) by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by Aptar or (ii) as a transfer of stock options without value to a "family member" (as defined in Form S-8) if approved by the Management Development & Compensation Committee. Except to the extent permitted by the foregoing sentence, each award may be exercised or received during a participant's lifetime only by the participant or the participant's legal representative or similar person. No award may be transferred by a participant for value or consideration.

*Fair Market Value*. Fair market value on any date means the closing price of a share of common stock on the New York Stock Exchange on that date (or, if such date is not a trading date, on the next preceding date that was a trading date). On March 10, 2023, the closing price of our common stock on the New York Stock Exchange was $112.56.

*Surrender*. If provided by the Management Development & Compensation Committee, a participant may surrender an award on such terms and conditions, and for such consideration, as the Management Development & Compensation Committee determines.

*Withholding*. The Management Development & Compensation Committee has the power to withhold, or require a participant to remit to Aptar, an amount sufficient to cover withholding taxes with respect to shares issuable and/or amounts payable pursuant to the 2018 Plan. If permitted by the Management Development & Compensation Committee, a participant may elect to satisfy such taxes by making a cash payment to Aptar, having shares issuable under the 2018 Plan withheld, by delivering other shares to Aptar, or with the proceeds from the sale of shares through an arrangement with a broker.

*Amendment of the Plan*. The Management Development & Compensation Committee may amend the 2018 Plan, subject to any requirement of stockholder approval required by applicable law, rule, or regulation. No amendment may materially impair the rights of the holder of any outstanding award without his or her consent.

*Effective Date and Term of the Plan*. The 2018 Plan became effective on May 2, 2018 and will terminate on May 2, 2028 unless terminated earlier by the Board or Management Development & Compensation Committee. Termination of the 2018 Plan will not affect the terms or conditions of any award granted prior to termination.

*Clawback of Awards*. Except to the extent prohibited by law, awards granted under the 2018 Plan and any cash payment or shares delivered pursuant to an award are subject to forfeiture and recovery by Aptar pursuant to any clawback or recoupment policy that Aptar may adopt from time to time, including any policy that Aptar may be required to adopt under the Dodd-Frank Act, or otherwise as required by law.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Included in this column are 928,255 PRSUs (at target). Under the terms of the PRSU award agreements, the vesting level of the PRSU may range from 0% to 200% based on Aptar's performance during the three-year performance period.

#### Federal Income Tax Consequences
The following is a brief summary of the U.S. federal income tax consequences of awards made under the 2018 Plan. This discussion does not address all aspects of the United States federal income tax consequences of participating in the 2018 Plan that may be relevant to participants in light of their personal investment or tax circumstances and does not discuss any state, local, or non-United States tax consequences of participating in the 2018 Plan. Each participant is advised to consult his or her particular tax advisor concerning the application of the United States federal income tax laws to such participant's particular situation, as well as the applicability and effect of any state, local, or non-United States tax laws before taking any actions with respect to any awards.

*Options*. A participant will not recognize any income upon the grant of a stock option. A participant will recognize compensation taxable as ordinary income (and subject to income tax withholding if the participant is an employee) upon exercise of a nonqualified stock option equal to the excess of the fair market value of the shares purchased over their exercise price, and Aptar (or the affiliate employer) will be entitled to a corresponding deduction, except to the extent limited by Section 162(m) of the Code. A participant will not recognize income (except for purposes of the alternative minimum tax) upon exercise of an ISO. If the shares acquired by exercise of an ISO are held for the longer of two years from the date the option was granted or one year from the date the shares were transferred, any gain or loss arising from a subsequent disposition of such shares will be taxed as long-term capital gain or loss, and Aptar (or the affiliate employer) will not be entitled to any deduction. If, however, such shares are disposed of within the above-described period, then in the year of such disposition the participant generally will recognize compensation taxable as ordinary income equal to the excess of the lesser of (i) the amount realized upon such disposition and (ii) the fair market value of such shares on the date of exercise over the exercise price, and Aptar (or the affiliate employer) will be entitled to a corresponding deduction, except to the extent limited by Section 162(m) of the Code.

*SARs*. A participant will not recognize any taxable income upon the grant of an SAR. A participant will recognize compensation taxable as ordinary income (and subject to income tax withholding if the participant is an employee) upon exercise of an SAR equal to the fair market value of any shares delivered and the amount of any cash paid by Aptar upon such exercise, and Aptar (or the affiliate employer) will be entitled to a corresponding deduction, except to the extent limited by Section 162(m) of the Code.

*Restricted Stock*. A participant will not recognize taxable income at the time shares subject to restrictions constituting a substantial risk of forfeiture are granted, and Aptar (or the affiliate employer) will not be entitled to a tax deduction at such time, unless the participant makes an election to be taxed at the time such

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

restricted stock is granted. If such election is made, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding if the participant is an employee) at the time of grant in an amount equal to the excess of the fair market value of the shares at such time over the amount, if any, paid for such shares. If such election is not made, the participant will recognize compensation taxable as ordinary income (and subject to income tax withholding if the participant is an employee) at the time the restrictions constituting a substantial risk of forfeiture lapse in an amount equal to the excess of the fair market value of the shares at such time over the amount, if any, paid for such shares. The amount of ordinary income recognized by a participant by making the above-described election or upon the lapse of the restrictions constituting a substantial risk of forfeiture is deductible by Aptar (or the affiliate employer) as a compensation expense, except to the extent limited by Section 162(m) of the Code.

*Restricted Stock Units*. A participant will not recognize taxable income at the time an RSU award is granted, and Aptar (or the affiliate employer) will not be entitled to a tax deduction at that time. Upon the payment or settlement of any such award with unrestricted shares of common stock or cash, the participant will recognize compensation taxable as ordinary income (subject to income tax withholding if the participant is an employee) in an amount equal to the fair market value of any shares delivered and the amount of any cash paid by Aptar. This amount is deductible by Aptar (or the affiliate employer) as compensation expense, except to the extent limited by Section 162(m) of the Code.

*Section 162(m) of the Code*. Section 162(m) of the Code generally limits to $1 million the amount that a publicly held corporation is allowed each year to deduct for the compensation paid to each of the corporation's chief executive officer, the corporation's chief financial officer and certain other current and former executive officers of the corporation.

## Proposal 5: Ratification of the Appointment of PricewaterhouseCoopers LLP as the Independent Registered Public Accounting Firm for 2023
Aptar is asking stockholders to ratify the Audit Committee's appointment of PricewaterhouseCoopers LLP ("PwC") as Aptar's independent registered public accounting firm for the fiscal year ending December 31, 2023. PricewaterhouseCoopers LLP has audited Aptar's consolidated financial statements annually for over 30 years.

---

As described in its charter, the Audit Committee is responsible for the appointment, retention, termination, compensation and oversight of Aptar's independent registered public accounting firm. On an annual basis, the Audit Committee considers the engagement of the independent registered public accounting firm. In selecting PwC as Aptar's independent registered public accounting firm for fiscal 2023, the Audit Committee evaluated, among other factors:

● PwC's performance during fiscal year 2022 and in previous fiscal years, including the quality of PwC's services, the sufficiency of PwC's resources and the quality of the Audit Committee's ongoing discussions with PwC;

● PwC's tenure as the Company's independent registered public accounting firm and the depth of its understanding of our business, accounting policies and practices and internal control over financial reporting;

● the professional qualifications of PwC, the lead audit engagement partner and other key engagement partners;

● the scope of PwC's independence program and its processes for maintaining its independence;

● the scope of PwC's internal quality control program and the result of its most recent quality control reviews, including reviews by the Public Company Accounting Oversight Board;

● the appropriateness of PwC's fees for audit and non-audit services (on both an absolute basis and as compared to its peer firms); and

● the relative benefits, challenges, overall advisability and potential impact of selecting a different independent registered public accounting firm.

PwC rotates its lead audit engagement partner every five years; the Audit Committee interviews proposed candidates and selects the lead audit engagement partner.

Representatives of PwC are expected to attend the annual meeting and will have the opportunity to make a statement if they desire to do so. It is also expected that those representatives will be available to respond to appropriate questions.

&nbsp;&nbsp;&nbsp;&nbsp;(1) For Touya, Prieur and Gong, a portion of their STI is based on the Adjusted EBITDA improvement and core sales growth in the NEOs' areas of responsibility. See "Short-Term Incentives" later in this Compensation Discussion & Analysis.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Adjusted return on invested capital (or Adjusted ROIC) is defined as (i) adjusted earnings before net interest (but after taxes), which excludes the business transformation charges (restructuring initiatives), acquisition-related costs, purchase accounting adjustments related to acquisitions and investments and net unrealized investment gains and losses related to observable market price changes on equity securities, divided by (ii) the Company's average capital (*i.e.*, equity excluding currency effects plus net debt). The target is adjusted down for 0.2% for every $100M in acquisitions over the three-year performance period. The 0.2% adjustment assumes that over the performance period, the acquisition will become accretive to returns.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Total stockholder return (or TSR) is measured by price appreciation of the Company's common stock over a three-year performance period and reinvestment of dividends, and is compared to the TSR of the S&P 400 MidCap Index over such three year performance period.

### Compensation Philosophy and Objectives
Our compensation philosophy and objectives are, first and foremost, to fairly and competitively compensate our executives for growing our business and increasing value for stockholders and, secondly, to retain our experienced management team.

We believe that the following factors are supportive of our compensation objectives:

### Stockholder Feedback on Compensation Practices

---

| | |
|:---|:---|
| ![Graphic](atr-20230503xdef14a_a117.jpg) | The Management Development and Compensation Committee considered the continued support that our proposal on executive compensation received from stockholders at our 2022 annual meeting of stockholders, at which approximately 99% of votes cast (excluding abstentions and broker non-votes) were in favor of our compensation policies and practices. Overall, we achieved a five-year average vote of 98% of votes cast. The Management Development and Compensation Committee determined that the Company's executive compensation philosophy and objectives and compensation elements continued to be appropriate and no changes were made to our executive compensation program in response to the advisory vote. However, in connection with its regular review of the Company's executive compensation program, in 2022, the Management Development and Compensation Committee modified the Company's executive compensation program to incorporate into its equity awards double trigger vesting provisions in the event of a change in control, beginning with the 2022 annual equity awards, and adopted a stand-alone clawback policy allowing for the recoupment of incentive compensation in the event of a financial statement restatement. |

---

---

| |
|:---|
| &nbsp;&nbsp;**Factors Considered when Determining Compensation Levels:** |
| &nbsp;&nbsp;&nbsp;&nbsp;**Industry Data**<br>● We benchmark against size-appropriate published general industry survey data for all roles.<br>|
| &nbsp;&nbsp;&nbsp;&nbsp;**Peer Data Review**<br>● We review proxy data from the Company's compensation peer group for the CEO and CFO roles.<br>|
| &nbsp;&nbsp;&nbsp;&nbsp;**Individual**<br>● We understand the importance of retaining a talented senior management team, which manages a globally diverse business while balancing a unified, single management team with a high focus on delivering results. We review past compensation levels and place a high value on the experience of senior managers.<br>|

---

The Management Development and Compensation Committee has historically intended to create a compensation program for NEOs that generally targets cash compensation at the median and long-term compensation between the 50th and 75th percentiles compared to the relevant market data. The Management Development and Compensation Committee may deviate from its targeted positioning based on circumstances such as executive tenure, Company/Segment performance or individual performance. The benchmarking study conducted by Pay Governance used for evaluating Aptar's 2022 executive compensation program, described in further detail below, noted the following high-level findings for our executive officers, including NEOs, as compared to general industry survey data:

● Base salaries generally fell between the 35 <sup>th</sup> and 65 <sup>th</sup> percentiles;

● Target cash compensation levels generally ranked between the 45 <sup>th</sup> and 65 <sup>th</sup> percentiles;

● Long-term performance incentives were generally between the 50th and 75th percentiles; and

● Target total direct compensation levels (salary + target bonus + target LTI values) were generally between the 50th and 75th percentiles.

For 2022, the Management Development and Compensation Committee confirmed the compensation peer group ("Peer Group") which serves as part of the basis for the Management Development and Compensation Committee's decisions regarding the pay of the CEO and CFO. Peer group data were developed from proxies and supplemental information reported by several compensation surveys for CEOs and CFOs at industrial companies comparable in size to Aptar. In consultation with Pay Governance, the Management Development

and Compensation Committee and management used the following characteristics to assess the Company's current peers as well as to identify any potential replacements:

● Compete with Aptar for market share, operate in similar industries (e.g., packaging, specialty chemicals, specialty materials) and are based in the U.S.;

● Provide similar intermediate products (e.g., structured materials, packaging, closures, spray products) to similar end-use markets (e.g., consumer, beauty, home, pharmaceutical, medical, healthcare, food, beverage);

● Fall within a reasonable range of Aptar's size and scale based on several factors (e.g., revenue, assets, invested capital, number of employees, market capitalization);

● Earn a considerable amount of their revenue outside of the U.S.;

● Appear to be valued like Aptar by the stock market based on their market capitalization to revenue vs. Aptar's; and

● Compete with Aptar for senior executive talent (companies Aptar potentially would recruit senior talent from, and possibly lose senior talent to).

The Peer Group is not a comprehensive list of all of Aptar's competitors. Rather, it includes a set of companies that meet most, but not necessarily all, of the peer group selection criteria noted above. The Management Development and Compensation Committee approved the Peer Group for evaluating target pay levels of the CEO and CFO as well as for assessing Aptar's executive pay practices and policies. The following companies were included in the Peer Group for 2022, which was the same Peer Group used to evaluate 2021 compensation decisions:

The Management Development and Compensation Committee reviews compensation survey information prepared by its compensation consultant for the CEO and other executive officer positions annually. Consistent with prior years, the compensation elements evaluated by Pay Governance in 2022 were base salary, target annual cash incentives, target total cash compensation (the sum of base salaries and target cash incentives), target LTI, and target total direct compensation (the sum of target total cash compensation and target LTI). In considering compensation for the CEO and CFO, the Management Development and Compensation Committee considered proxy peer group compensation data in addition to the compensation survey information prepared by Pay Governance. When determining the 2022 compensation opportunities of executive officers other than Mr. Tanda, the Management Development and Compensation Committee also reviewed recommendations furnished by Mr. Tanda, including salary, target annual cash incentive and target LTI recommendations. In 2022, Mr. Tanda, participated in all discussions regarding salaries and incentive compensation for all of our executive officers, except during discussions regarding his own compensation. Mr. Tanda made suggestions or recommendations during these discussions; however, all deliberations and determinations regarding the compensation of our executive officers were made solely by the Management Development and Compensation Committee.

Targeted base salary, annual incentive opportunities and LTI grant values were provided by Pay Governance from several compensation surveys covering U.S. and non-U.S. executives and included general industry

data for hundreds of companies. Wherever possible, the market data was adjusted to Aptar's revenue size or the size of the position's operating unit. The same compensation elements also were reviewed by Pay Governance in the analysis of peer group data for Messrs. Tanda and Kuhn.

As noted earlier, based on Pay Governance's benchmarking analysis that was furnished to the Management Development and Compensation Committee, Aptar's 2022 total direct compensation for the NEOs, in aggregate was generally positioned between the 50th and 75th percentiles of the published survey data. Specifically, most elements of total direct compensation for the CEO and CFO were positioned within +/- 10% of the 50th percentile with respect to the 2022 Peer Group.

### Elements of Our Executive Compensation Program
There are three main elements of our compensation program which are described below.

**Salary.** The salary level of the CEO is established by the Management Development and Compensation Committee each January after evaluating individual performance and discussing the market data provided by Pay Governance. The salary levels of the other NEOs are also set each January after evaluating and discussing the recommendations of the CEO and reviewing the market data provided by Pay Governance for the other NEO positions. In 2022, the Management Development and Compensation Committee adjusted the salaries of our NEOs from the 2021 levels as listed below. In lieu of adjusting the base salary for the CEO, the Management Development and Compensation Committee elected to increase his LTI value from 450% to 470% to further enhance his ties to performance-based compensation in general and long-term equity incentives in particular.

---

| | | | |
|:---|:---|:---|:---|
| **Name** | **2022 Salary** | **2021 Salary** | **% Increase** |
| **Tanda** | $1118500 | $1118500 | —% |
| **Kuhn(1)** | $671174 | $645216 | 4% |
| **Touya(2)** | $561328 | $607043 | (8)% |
| **Prieur(3)** | $603011 | $598635 | 1% |
| **Gong** | $494647 | $477920 | 4% |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Mr. Kuhn's compensation considers the elimination of the annual car benefit, the value of which is now included in his 2022 salary and accounts for a portion of the increase.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Mr. Touya's compensation is denominated in Euros and was translated to U.S. dollars using the average exchange rate for the year. His 2022 salary in Euros is 530,000, which represents a 3% increase over his 2021 salary in Euros. Mr. Touya's decrease is due to exchange rate fluctuations.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Mr. Prieur's compensation is denominated in Swiss Francs and was translated to U.S. dollars using the average exchange rate for the year. His 2022 salary in Swiss Francs is 562,000, which represents a 3% increase over his 2021 salary in Swiss Francs.

### Short-term Incentives ("STI").
The Management Development and Compensation Committee continues to maintain the Company's historical approach to linking pay to performance. The STI plan is based on STI Adjusted EBITDA and core sales growth, with the STI design placing nearly twice as much emphasis on profitability rather than top-line growth and emphasizing segment results with different goals for each segment. The Management Development and Compensation Committee chose STI Adjusted EBITDA and core sales growth as performance measures because they are viewed as being directly tied into goals that we believe are critical to our business strategy and the creation of stockholder value.

The Company goals under the STI place emphasis on continuous improvement over the prior year's results. As a result, NEOs earn no STI payout if results are less than prior year performance, with results equal to the prior year producing a threshold payout (50% of target). Further, the Company continues to use year-over-year consistency for determining target and maximum payouts. Under this approach, the Management Development and Compensation Committee approved growth rates in EBITDA and core sales, which do not change from year to year because they are based on the Company's long-term expectations of the business. For 2022, the amount of our NEOs' STI was calculated based on (i) target STI opportunity and (ii) improvement in Company performance (and segment results where appropriate) from the prior year. For

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

Messrs. Touya and Prieur and Ms. Gong, the performance factors are further weighted 40% Company performance and 60% on their respective areas of responsibility.

The target STI opportunity is a percentage of each NEO's base salary, and is determined annually based on market data, the Company's historical pay practices, individual role and responsibilities, and individual performance. For 2022, the target STI opportunities, as a percentage of base salary, did not increase for the NEOs.

The following illustrates how the 2022 STI payouts were calculated:

![Graphic](atr-20230503xdef14a_a119.jpg)

At the beginning of 2022, the Management Development and Compensation Committee established the following growth in Company performance and weightings for 2022 to be used to determine the amount of each NEO's 2022 STI. These growth objectives are consistent with prior years, as well as with the Company's continuous improvement mindset. They also consider our economic expectations for our different segments.

\*&nbsp;&nbsp;&nbsp;&nbsp; Includes the impact of the waiver of the cliff threshold with respect to the 2020 STI as part of the Company's response plan to the COVID-19 pandemic.

The Management Development and Compensation Committee believes it is important to encourage executive officer stock ownership and provide opportunities to increase equity ownership. For those reasons, an executive officer may elect to receive up to 50% of his or her STI in the form of RSUs. If an executive elects to receive a portion of his or her STI in RSUs, the executive will also receive an additional 20% of the elected amount in the form of RSUs to recognize the difference in earned cash STI payouts and RSUs that remain at risk to changes in stock price as well as continued service. The value of each RSU is determined by the closing share price on the NYSE on the day preceding the date of grant. RSUs vest over a three-year period, with one third vesting on each of the first three anniversaries of the grant date, and the RSUs converting into our common stock following the vesting date. Recipients of RSUs may not vote the units in stockholder votes and they do not earn or receive any dividend payments on the units. Messrs. Tanda, Kuhn and Gong elected to receive a portion of their 2022 STI in RSUs, which election applied to the payouts described above.

### Long-term Performance Incentives ("LTIs").
We manage our business for the long-term benefit of all stakeholders and consequently we believe that it is important that our NEOs receive a substantial portion of their compensation in the form of long-term incentives (LTI). Additionally, we believe LTI compensation in the form of equity awards provide a strong alignment between the interests of our NEOs and our stockholders. The Management Development and Compensation Committee also believes that long-term equity awards are an essential tool in promoting executive retention. Consistent with our LTI grants for the past several years, the annual LTI grants in 2022 consisted of RSUs that vest based on continued service and PRSUs that vest based on achieving pre-established performance objectives. Dividends are not declared or paid with respect to RSUs or PRSUs. In addition, 2022 represented the first year that the LTI grants included double trigger vesting provisions in the event of a change in control.

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

### Setting Award Value:
In early 2022, the Management Development and Compensation Committee granted the NEOs LTI awards. In approving the 2022 LTI awards and based on a review of market data, as reported by Pay Governance, the Management Development and Compensation Committee also approved a market-based approach to determining LTI values, which calculates the grant value delivered to award recipients based on current market price rather than accounting values. The Management Development and Compensation Committee believes that the use of a market-based approach to determine the number of shares to grant aligns with prevalent market practice and is more representative of the intended targeted value of compensation to be granted to participants. Target amounts of the LTI awards are also based on individual roles and responsibilities, individual performance and market data. The target LTI amount for Mr. Tanda was increased from 450% to 470%, in lieu of receiving a base salary adjustment to further align his target direct compensation with the interests of our stockholders. The target LTI amount, as a percentage of base salary, for the other NEOs did not change as compared to 2021. Once the LTI target award value was determined for each NEO, the award was divided between PRSUs and RSUs, weighted 60% and 40%, respectively. The weights between LTI elements are intended to strike a reasonable balance between performance-based grants (PRSUs) and time or service-based grants (RSUs), consistent with the Company's pay philosophy and principles.

The following table sets forth the target award value, as of the date of grant, of the 2022 LTI awards received by each NEO.

---

| | |
|:---|:---|
| **NEO** | **Target Value of LTI award(1)** |
| **Tanda** | $5256950 |
| **Kuhn** | $1335598 |
| **Touya** | $1016333 |
| **Prieur** | $1052081 |
| **Gong** | $865632 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Because the amounts reported in this column represent the market-based targeted grant values, they differ from the amounts reported in the 2022 Summary Compensation Table, which are determined in accordance with applicable accounting rules based on the stock price at the date of grant.

### PRSUs:
PRSUs are measured over a three-year period, with the measurement date beginning in the 1<sup>st</sup> quarter of the initial year of the performance period and ending in the 1<sup>st</sup> quarter three years thereafter. For 2022, the Management Development and Compensation Committee granted PRSUs as 60% of the target LTI award, which vest based on the Company's Adjusted ROIC and relative TSR performance over a three-year performance period, with potential vesting ranging from 0% to 200% of the target number of shares subject to the award (the "Target Shares") as follows:

● Adjusted ROIC over the three-year performance period, which consists of 35% of the Target PRSUs. Adjusted ROIC is defined as (i) adjusted earnings before net interest (but after taxes), which excludes the business transformation charges (restructuring initiatives), acquisition-related costs, purchase accounting adjustments related to acquisitions and investments and net unrealized investment gains and losses related to observable market price changes on equity securities, divided by (ii) the Company's average capital (*i.e.,* equity excluding currency effects plus net debt). The target is reduced by 0.2% for every $100M in acquisitions which is weighted for time outstanding in the performance period. The 0.2% adjustment assumes that over the performance period, the acquisition will become accretive to returns. The Management Development and Compensation Committee established the Adjusted ROIC performance levels to be achievable, but required the strong and consistent performance of the Company over the three-year performance period.

● TSR relative to the S&P 400 MidCap Index over the three-year performance period, which consists of 65% of the Target PRSUs. TSR is measured by share price appreciation of the Company's common stock over the three-year performance period and reinvestment of dividends, as compared to the

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

TSR of the S&P 400 MidCap Index over the performance period. For the TSR component, the vesting will be determined in accordance with the following schedule:

---

| | | |
|:---|:---|:---|
| **Performance Level** | **Company TSR Percentile Rank as compared to the S&P 400 MidCap** | **% of Target Shares to Vest\*** |
| Below Threshold | Below 25th percentile | —% |
| Threshold | 25th percentile | 50% |
| Target | 50th percentile | 100% |
| Maximum | 75th percentile | 200% |
| <br>\*&nbsp;&nbsp;&nbsp;&nbsp; If the Company's TSR for the Performance Period is negative, the vesting level will not exceed the target level of vesting. | <br>\*&nbsp;&nbsp;&nbsp;&nbsp; If the Company's TSR for the Performance Period is negative, the vesting level will not exceed the target level of vesting. | <br>\*&nbsp;&nbsp;&nbsp;&nbsp; If the Company's TSR for the Performance Period is negative, the vesting level will not exceed the target level of vesting. |

---

### RSUs:
The remaining component of the 2022 LTI program consisted of time-based RSUs, which vest over a three-year service period, subject to the NEO's continued employment through the applicable vesting date except to the extent an event triggers accelerated vesting of the 2022 RSUs under the terms of the award agreement or his or her employment or other agreement, as applicable. RSUs are included as a component under the annual LTI program to further enhance the retentive aspect of the Company's executive compensation program and further align the interests of our NEOs with the long-term interests of the Company's stockholders as the value of the RSUs remains at-risk and fluctuates based on our stock price performance.

### 2019 PRSU Awards:
Under the terms of the 2019 PRSUs, March 2022 was the end of the final year of the three-year performance period for the awards. The 2019 PRSUs were eligible to vest based on Adjusted ROIC and the Company's relative TSR, weighted 35% and 65%, respectively, with Adjusted ROIC as defined above and TSR measured as described above for the 2022 PRSUs. The 2019 PRSU performance objectives and the achievement levels are set forth in the tables below.

&nbsp;&nbsp;&nbsp;&nbsp;(1) In accordance with the terms of the award agreements, the original ROIC targets are adjusted down 0.2% for every $100M in acquisitions, which is weighted for time outstanding in the performance period.

Based on performance over the three-year performance period, presented below are the number of shares earned for each of the participating NEOs. The earned shares are also presented in the 2022 Option Exercises and Stock Awards Vested Table, presented on page 62 below.

### Change in 2023 LTI Program:
As disclosed above, in 2022, the target LTI award was comprised of 60% PRSUs and 40% time-based RSUs. Beginning in 2023, the Management Development and Compensation Committee has determined to add premium-priced options into the LTI mix with options that have an exercise price with a 10% premium to the Company's stock price on the date of grant. As a result of this change, in 2023, the target LTI award is comprised of 50% PRSUs, 25% premium-priced options and 25% time-based RSUs. The Management

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

Development and Compensation Committee believes this change enhances the performance orientation of the Company's LTI program by increasing awards tied to performance-based components from 60% to 75% of target award value, further aligning the Company's pay program with the interests of stockholders and balancing relative stock price performance with absolute improvements in our stock price.

### Post-Termination compensation.
The employment agreements of our NEOs provide for guaranteed minimum salary levels, death benefits, non-competition clauses and post-termination commitments. The post-termination commitments do not significantly affect the Management Development and Compensation Committee's decisions concerning other compensation elements. We believe that the post-termination commitments included in the NEOs' agreements are not substantially different from what is typical at other companies with revenues similar to those of Aptar. On February 17, 2022, the Company and each of Mr. Tanda, Mr. Kuhn and Ms. Gong entered into employment agreement amendments that expanded the "good reason" definition to include customary "good reason" triggers for severance benefits in connection with a change in control. The Management Development and Compensation Committee approved this change after considering market practices.

Additional information about the employment agreements, including definitions of key terms and a quantification of benefits that would have been received by our NEOs had termination occurred on December 31, 2022, is found under "Potential Payments Upon Termination of Employment."

### Retirement Plan Arrangements.
We also offer pension plans to our employees, including NEOs. Additional information regarding our pension plans is found under "Pension Benefits."

We maintain profit sharing and savings plans for our employees, including NEOs. These plans permit employees to make such savings in a manner that is relatively tax efficient.

### Perquisites.
Perquisites have historically been an insignificant percentage of overall NEO compensation and therefore generally do not affect the decisions of the Management Development and Compensation Committee when determining other elements of compensation. These perquisites can include a company-provided automobile and supplemental life insurance, among others. Beginning in 2021, the Company began eliminating the automobile benefit for U.S. NEOs, with such benefit being phased out as leases expire. The Company provides competitive perquisites for NEOs on an expatriate assignment, which it believes are consistent with local market practices. For example, pursuant to the terms of her employment agreement, Ms. Gong will receive expatriate benefits relating to her current international assignment in China, which began in October 2018. The additional benefits that she receives are directly related to the additional expenses Ms. Gong incurs as a result of her China assignment. Her benefits include automobile and driver (including insurance, maintenance, reasonable fuel, taxes and vehicle registration costs), educational assistance, international health insurance, travel for two (2) annual trips to the United States for Ms. Gong and her immediate family, housing allowances, tax equalization payments and preparation services, and reimbursement for repatriation to the United States upon certain termination events. Similarly, on January 25, 2022, the Company and Mr. Touya entered into an Expatriate Letter Agreement pursuant to which Mr. Touya's existing employment agreement will be suspended while he is on assignment with the Company in the U.S. and he will receive compensation and benefits consistent with similarly-situated employees of the Company on an expatriate assignment or as otherwise approved by the Management Development and Compensation Committee, which includes, among other items, a company car, educational assistance, a housing allowance and tax equalization payments. The Management Development and Compensation Committee believes it is necessary to provide NEOs with perquisites similar to those provided by other companies in order to recruit and retain the best executive talent or, in the case of expatriate benefits, to induce the executives to accept the expatriate assignment and retain them during the desired period of expatriate service. The Management Development and Compensation Committee reviews the perquisites provided to its NEOs on a regular basis.

### Stock Ownership
Under the Company's stock ownership guidelines, the executive officers must own Company common stock and/or hold RSUs representing a value that is as follows: for the CEO, six times his or her base salary and for

the remaining executive officers, three times their base salary. Under the guidelines, executive officers must retain 50% of net after taxes shares from any equity vesting until the stock ownership guidelines are met. As of the record date, each NEO was in compliance with the guidelines as presented in the table below.

### Management Development and Compensation Committee's Use of Consultants and Consultant's Independence
The Management Development and Compensation Committee has responsibility for approving the compensation programs for our NEOs and acts pursuant to a charter that has been approved by our Board and is available through the Corporate Governance link on the Investor Relations page of the Aptar website located at: investors.aptar.com. Under this charter, the Management Development and Compensation Committee has the authority to retain outside advisers as deemed necessary, and in 2022 the Management Development and Compensation Committee retained Pay Governance as its independent compensation consultant. The Management Development and Compensation Committee has determined that Pay Governance is independent according to the advisor independence factors outlined by the NYSE and its services to the committee do not raise any conflicts of interest.

### Stock Trading Guidelines
We have an Insider Trading Policy that applies to senior management, including our NEOs. The Insider Trading Policy prohibits our senior management from engaging in selling short our common stock or engaging in hedging, pledging or offsetting transactions regarding our common stock.

### Clawback Policy
The Management Development and Compensation Committee has adopted a clawback policy in the event the Company is required to prepare an accounting restatement due to material non-compliance with a financial reporting requirement under the federal securities laws. Under the policy, the Management Development and Compensation Committee will, to the extent legally permitted, require reimbursement of that portion of any incentive compensation earned by an executive officer during the three-year period preceding the date on which the Company is required to prepare the restatement, which is in excess of what would have been paid or earned by such executive officer had the financial results been properly reported. The Company continues to monitor this policy to ensure that it is consistent with applicable laws and will review and modify the policy as necessary to reflect the final NYSE listing rules adopted to implement the compensation recovery requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Stock Award compensation for each NEO includes the fair value of RSUs granted in lieu of a portion of the executive's annual short-term incentive for that year, at the executive's election, and additional RSUs granted to an executive officer who made such election. The value of the additional RSUs granted represents 20% of the value of the annual performance incentive (non-equity incentive compensation plan amount) that was taken in the form of RSUs in lieu of cash. RSUs vest over a three-year period. The number of RSUs granted to Messrs. Tanda, Kuhn, and Ms. Gong with respect to the 2022 performance is included in the table below. The number of RSUs granted was determined by dividing the amount of the annual performance incentive taken in RSUs and the additional 20% on that amount by the market price of our common stock on February 24, 2023, discounted for dividends not received during the vesting period.

PRSUs in connection with 2022 LTI grants were granted on March 14, 2022. Amounts shown in the column regarding PRSUs do not reflect dollar amounts actually received by the NEOs. Instead, these amounts represent the aggregate grant date fair value of the PRSUs granted in the year indicated computed in accordance with ASC Topic 718. The grant date fair value of the TSR portion of the PRSUs is determined using a Monte-Carlo simulation model and based upon a discounted cash flow analysis of

the probability-weighted payoffs of a share-based payment assuming a variety of possible stock price paths and represents the estimate of aggregate compensation cost to be recognized over the requisite service period determined as of the grant date under ASC Topic 718. The grant date fair value of the ROIC portion of the PRSUs is determined based on the probable satisfaction of the performance conditions at the time of grant and the closing stock price on such date in accordance with ASC Topic 718.

The amounts included in the Stock Awards column for the PRSUs granted during 2022 are calculated based on the probable satisfaction of the performance conditions for such awards as of the date of grant. Assuming the highest level of performance is achieved for the portion of the PRSUs relating to the ROIC component, the maximum grant date fair value for the ROIC component would be as follows: Mr. Tanda—$2,207,866; Mr. Kuhn—$561,053; Mr. Touya—$426,903; Mr. Prieur—$441,802; and Ms. Gong—$363,462. Under FASB ASC Topic 718, the vesting condition related to the TSR portion of the PRSUs is considered a market condition and not a performance condition. Accordingly, there is no grant date fair value below or in excess of the amount reflected in the table above for the NEOs that could be calculated and disclosed based on achievement of the underlying market condition. Assumptions used in the calculation of the expense related to the stock awards can be found in Note 16, "Stock-Based Compensation" to Aptar's audited financial statements for the year ended December 31, 2022, included in Aptar's Annual Report on Form 10-K filed with the SEC on February 17, 2023 ("Aptar's Financial Statements").

&nbsp;&nbsp;&nbsp;&nbsp;(2) Amounts reported in this column represent the cash portion received under the STI and are presented in the fiscal year in which they were earned. These amounts were paid in February of the following year once the consolidated financial results of Aptar were completed. Please see footnote 1 above for a summary of the RSU component of the STI, which was awarded in early 2023 and is reflected in the table above as 2022 compensation.

&nbsp;&nbsp;&nbsp;&nbsp;(3) All of these amounts relate to changes in pension values. Assumptions used to calculate the change in the present value of accrued benefits were the same as those disclosed in Note 9, "Retirement and Deferred Compensation Plans" to Aptar's Financial Statements.

&nbsp;&nbsp;&nbsp;&nbsp;(4) The amount of other compensation in 2022 includes Company contributions to profit sharing and savings plans, premiums related to Company-provided term life insurance and supplemental disability insurance, and amounts related to a Company-provided automobile for all NEOs. The amount of other compensation in 2022 for Mr. Tanda includes approximately $50,000 related to Company provided disability insurance. The amount of other compensation in 2022 for Mr. Touya includes expatriate assignment related costs including approximately $45,000 in tuition, $61,000 in cost of living adjustments, $270,000 in rent, and $612,000 in tax reimbursements related to the tax impact based on his expatriate assignment. The amount of other compensation for Mr. Touya also includes Company contributions related to a profit share program of approximately $38,000. The amount of other compensation for Ms. Gong includes payments for housing of approximately $87,000, cost of living adjustments of $58,000 and approximately $130,000 in tax reimbursements related to the tax impact based on her expatriate assignment. The amounts paid with respect to Mr. Touya and Ms. Gong are valued based on the aggregate incremental cost to the Company and represents the amounts paid to, or on behalf of, the executive.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Mr. Touya's compensation is denominated in Euros and was translated to U.S. dollars using the average exchange rate for the year, except for the annual performance incentive amount which was translated using the spot exchange rate on the date the amount was determined.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Mr. Prieur's compensation is denominated in Swiss Francs and was translated to U.S. dollars using the average exchange rate for the year, except for the annual performance incentive amount which was translated using the spot exchange rate on the date the amount was determined.

&nbsp;&nbsp;&nbsp;&nbsp;(1) During fiscal year 2022, NEOs received three types of plan-based awards: PRSUs, RSUs and Annual Short-Term Incentives (in cash) ("STI").

&nbsp;&nbsp;&nbsp;&nbsp;(2) Amounts represent target and maximum STI opportunities under the 2022 STI. The amount actually paid to each NEO is included in the Stock Awards column and the Non-Equity Incentive Plan Compensation column in the 2022 Summary Compensation Table. See "Compensation Discussion and Analysis—Elements of Our Compensation Programs—Annual Performance Incentives" for further information regarding the 2022 STI.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Amounts represent PRSUs that vest over the 2022-2024 performance period based on the Company's Adjusted ROIC and TSR performance. See "Compensation Discussion and Analysis—Elements of Our Compensation Programs—Long-term Performance Incentives" above for more information about the PRSUs, including the pre-established performance periods and performance measures. See the footnotes to the "2022 Outstanding Equity Awards at Fiscal Year-End" table below for a description of the PRSU vesting schedules.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Awards granted on February 25, 2022 represent RSUs granted to Messrs. Tanda, Kuhn, and Ms. Gong at their election to receive RSUs in lieu of a portion of their 2021 annual performance incentive (paid/awarded in 2022) and an additional 20% of the elected amount granted to those officers making such election, which were previously reported as compensation in the 2021 Summary Compensation Table. See "Compensation Discussion and Analysis—Elements of Our Compensation Programs—Long-term Performance Incentives" above for more information regarding the 2022 LTI RSUs, including the vesting schedules.

&nbsp;&nbsp;&nbsp;&nbsp;(5) RSUs and PRSUs reflected in this column are reported in accordance with FASB ASC 718 (excluding the effect of estimated forfeitures) and, in the case of the PRSU awards, based upon the probable outcome of certain performance conditions.

### Employment Agreements

#### Tanda Employment Agreement
Mr. Tanda's employment agreement provides for employment through December 31, 2024, unless earlier terminated, at a minimum salary of $1,118,500 (which is the 2023 salary approved by the Management Development and Compensation Committee) per year, which amount may be increased (but not decreased) over the term of the agreement. The employment agreement automatically extends for one additional year each January 1st, unless terminated, but may not be extended beyond December 31, 2030.

If Mr. Tanda's employment ends on account of death, Mr. Tanda's estate will receive one-half of the base salary that Mr. Tanda would have received until the second anniversary of his death and a lump sum payment in lieu of a supplemental life insurance benefit if Mr. Tanda is not covered by such insurance at the time of his death. If his employment ends due to the expiration of the employment agreement as a result of non-renewal by the Company, Mr. Tanda is entitled to receive an amount equal to one year's base salary and his target annual performance incentive. If Mr. Tanda is terminated without "cause," he is entitled to receive 1.5 times (i) his base salary then in effect and (ii) the greater of (x) his target annual performance incentive for the year in which he was terminated and (y) the average of the annual performance incentives paid to him for the two preceding years, paid in 18 equal monthly installments, as well as the medical, disability and life insurance benefits he would have otherwise received for a period of 18 months following the termination date and a prorated annual bonus based on actual performance.

In addition, in the event of Mr. Tanda's termination of employment other than for cause and not within two years following a change in control, Mr. Tanda would remain eligible for a prorated annual bonus based on actual performance, but only if such termination occurs during the third or fourth quarter of the Company's fiscal year.

After a "change in control" (as defined in the employment agreement), if Mr. Tanda's employment is terminated by the Company or its successor other than for "cause," disability or death, or if Mr. Tanda terminates his employment for "good reason," in each case within two years following the change in control, Mr. Tanda is entitled to receive a lump-sum payment equal to (i) three times his highest annualized salary during the 12 month period preceding the termination and (ii) three times the average of the annual performance incentives in respect of the three years immediately preceding the year in which the change in control occurs, plus a prorated annual performance incentive equal to an amount at least equal to the average of the annual performance incentives in respect of the three years immediately preceding the year in which the change in control occurs, the continuation of medical, disability and life insurance benefits for three years.

The employment agreement also contains certain noncompetition and nonsolicitation covenants prohibiting Mr. Tanda from, among other things, becoming employed by a competitor of the Company for a period of 18 months or two years following termination (depending on the nature of the termination).

#### Employment Agreements of Other NEOs
The employment agreements of Mr. Kuhn and Ms. Gong automatically extend for one additional year each January 1st, unless either the Company or the executive terminates such automatic extension by written notice to the other party at least 30 days prior to the automatic extension date, but in no event will the employment agreements continue later than December 31, 2024 (in the case of Mr. Kuhn) and December 31, 2034 (in the case of Ms. Gong) and (ii) that Mr. Kuhn and Ms. Gong will receive minimum annual salaries of $681,000, and $495,000 respectively (which are the 2023 salaries that were approved by the Management Development and Compensation Committee). These annual salaries may be increased (but not decreased) over the remaining terms of the agreements. In addition to participation in executive benefit programs on the same basis as other executives, Mr. Kuhn and Ms. Gong are entitled to additional term life and supplementary long-term disability insurance coverage.

If the employment of Mr. Kuhn, or Ms. Gong ends on account of death, the executive's estate will receive one-half of the annual salary that the executive would have received until the second anniversary of the executive's death and a lump sum payment in lieu of a supplemental life insurance benefit if the executive is not covered by such insurance at the time of death. If the employment of Mr. Kuhn, or Ms. Gong ends due to the expiration of the agreement, the executive is entitled to receive an amount equal to one year's base salary (based on the salary then in effect) and medical and life insurance benefits the executive would have

If Mr. Kuhn, or Ms. Gong terminates the agreement without "good reason" (as defined in the agreement), the executive is not entitled to payments or benefits under the employment agreement (other than certain accrued amounts and plan benefits which by their terms extend beyond termination of employment and the prorated annual bonus described in the next paragraph). If Mr. Kuhn, or Ms. Gong is terminated without "cause" (as defined in the agreement), the executive is entitled to receive the executive's base salary then in effect (at the times it would have been paid) until the date on which the agreement was scheduled to expire.

In addition, in the event of Mr. Kuhn's or Ms. Gong's termination of employment other than for cause and not within two years following a change in control, the executive would remain eligible for a prorated annual bonus based on actual performance, but only if such termination occurs during the third or fourth quarter of the Company's fiscal year.

After a change in control of the Company, if Mr. Kuhn, or Ms. Gong are terminated by the Company or its successor other than for cause, disability or death, or if Mr. Kuhn, or Ms. Gong terminates the executive's employment for "good reason," in each case within two years following the change in control, Mr. Kuhn and Ms. Gong are entitled to receive a lump-sum payment equal to (x) two and one-half times the executive's highest annualized salary during the 12 month period preceding the termination and (y) two and one-half times the average of the annual performance incentives in respect of the three fiscal years of the Company immediately preceding the fiscal year in which the change in control occurs, plus a prorated annual performance incentive equal to an amount at least equal to the average of the annual performance incentives in respect of the three fiscal years of the Company immediately preceding the fiscal year in which the change in control occurs, as well as the continuation of medical, disability, and life insurance benefits for two and one-half years.

The employment agreement for Mr. Kuhn and Ms. Gong also contains certain noncompetition and nonsolicitation covenants prohibiting the executive from, among other things, becoming employed by a competitor of the Company for a period of one year or two years following termination (depending on the nature of the termination).

Mr. Touya is party to an employment agreement with his prior French employer in accordance with the French Collective Bargaining Agreement of the Plastics Industry. The agreement of Mr. Touya was for an unlimited period; however, the Company and Mr. Touya retained the right to terminate the agreement in accordance with local law. The agreement provided for minimum annual salary to Mr. Touya of 567,000 (which is the 2023 local currency salary approved by the Management Development and Compensation Committee translated using the December 31, 2022 exchange rate). The agreement contains certain noncompetition and nonsolicitation covenants prohibiting Mr. Touya from, among other things, becoming employed by a competitor of the Company for a period of two years following termination (regardless of the reason for termination except for gross misconduct). In exchange for these covenants, Mr. Touya will receive, during the course of the non-compete period and except in the event of gross misconduct, an amount equal to 50% of the average monthly salary received by him during the 12 months prior to termination. In the event that Mr. Touya does not comply with the non-compete obligation, he will be required to pay to the Company an amount equal to two years' salary (based on the average monthly salary received during the 12 months prior to termination). In the event of any termination of employment (including following a change in control) other than for serious or gross misconduct and dismissal for unfitness, Mr. Touya would have been entitled to six months of his average gross salary received during the 12 months prior to termination. Average gross salary consists of Mr. Touya's base salary during the 12 months prior to dismissal as well as the average short-term incentive paid to Mr. Touya during the three years prior to dismissal. Mr. Touya would also receive payments under the French Collective Bargaining agreement as further described under "Potential Payments Upon Termination of Employment." On January 25, 2022, the Company and Mr. Touya entered into an Expatriate Letter Agreement pursuant to which Mr. Touya's existing employment agreement is suspended while he is on assignment with the Company in the United States, provided that if Mr. Touya's employment is terminated while he is on assignment in the United States under circumstances that would entitle him to severance under his existing employment agreement, Mr. Touya will receive severance consistent with the terms of his existing employment agreement.

The employment agreement of Mr. Prieur is in accordance with local Swiss law. The agreement of Mr. Prieur remains in effect until the end of the month in which Mr. Prieur reaches ordinary retirement age, according to then applicable Swiss law; however, the Company and Mr. Prieur have the right to terminate the agreement by giving six months advance written notice. The agreement may also be terminated with immediate effect for

good reason in accordance with local Swiss law. The agreement provides for a minimum annual salary to Mr. Prieur of $608,000 (which is the 2023 local currency salary approved by the Management Development and Compensation Committee translated using the December 31, 2022 exchange rate). Mr. Prieur's employment agreement also entitles him to a target STI opportunity equal to 75% of his base salary, an insurance policy covering his illness or death, a previnter insurance contribution and an automobile and mobile device in accordance with the Company's applicable policies. The agreement contains certain noncompetition and nonsolicitation covenants prohibiting Mr. Prieur from, among other things, becoming employed by a competitor of the Company for a period of two years following termination (in exchange for which Mr. Prieur will receive, during the course of the noncompete and nonsolicit period and regardless of the reason for termination except for cause, monthly payments equal to 50% of the average monthly gross salary (including bonus) received by him during the 12 months prior to termination and that Mr. Prieur will receive payments as described under "Potential Payments Upon Termination of Employment." In the event Mr. Prieur breaches the noncompete covenant, he will be required to pay to the Company an amount equal to one years' base salary (based on the average monthly salary (including short-term incentive) received during the 12 months prior to termination). In the event of Mr. Prieur's termination of employment by the Company for any reason except serious or gross negligence or dismissal for long-term sickness or disability, Mr. Prieur would be entitled to receive six months of his base salary and the prorated average annual gross bonus received by him during the three years prior to his dismissal. In the event of Mr. Prieur's termination of employment by the Company for any reason except serious or gross negligence or dismissal for long-term sickness or disability within two years following a change in control of the Company, he would be entitled to receive his annual base salary and the average annual gross bonus received by him during the three years prior to his dismissal.

For information regarding termination benefits, including benefits provided pursuant to employment agreements with the NEOs, see "Potential Payments Upon Termination of Employment."

### Pension Benefits

#### U.S. Employees
Substantially all of the U.S. employees of the Company and its subsidiaries hired before January 2021 are eligible to participate in the Company's Pension Plan, while employees hired in January 2021 or thereafter are eligible to participate in an enhanced 401(k) benefit plan. Employees hired before January 2021 were eligible to participate after six months of credited service and become fully vested after five years of credited service. The annual benefit payable to an employee under the Pension Plan upon retirement is computed as a straight life annuity equal to the sum of the separate amounts the employee accrues for each of his or her years of credited service under the Plan. Such separate amounts are determined as follows: for each year of credited service through 1988, 1.2% of such year's compensation up to the Social Security wage base for such year and 1.8% (2% for years after 1986) of such year's compensation above such wage base, plus certain increases put into effect prior to 1987; for each year after 1988 through the year in which the employee reaches 35 years of service, 1.2% of such year's "Covered Compensation" and 1.85% of such year's compensation above such "Covered Compensation" and for each year thereafter, 1.2% of such year's compensation. The employee's compensation under the Pension Plan for any year includes all salary, commissions and overtime pay and, beginning in 1989, annual performance incentives, and STI subject to such year's limit applicable to tax-qualified retirement plans. The employee's "Covered Compensation" under the Pension Plan for any year is generally the average of the Social Security wage base for each of the 35 years preceding the employee's Social Security retirement age, assuming that such year's Social Security wage base will not change in the future. Normal retirement under the Pension Plan is age 65 and reduced benefits are available as early as age 55 provided that the employee has completed 10 years of service. If an employee has completed 10 years of service and elects to retire and receive pension benefits before age 65, the benefit will be calculated in the same manner as under normal retirement conditions, but will be permanently reduced for each month the benefit commences prior to age 65. The reduction factors are: 1/180 for each of the first 60 months, and 1/360 for each additional month that is in advance of the normal retirement age. Benefits are not subject to reduction for Social Security benefits or other offset items.

U.S. employees of the Company and its subsidiaries participating in the Pension Plan are also eligible for the Company's non-qualified supplemental retirement plan ("SERP"). The annual benefit payable to an employee under the SERP upon retirement is computed as a straight life annuity equal to the sum of the separate amounts the employee accrues for each of his or her years of credited service under the SERP. The annual

accrued benefits are determined as follows: for each year of credited service through the year in which the participant reaches 35 years of service, 1.85% of the participant's "Supplemental Earnings;" and for each year after 35 years of credited service, 1.2% of such year's "Supplemental Earnings." "Supplemental Earnings" is generally the difference between (i) the participant's earnings calculated as if the limitation of Section 401(a)(17) of the Internal Revenue Code were not in effect and (ii) the participant's recognized earnings under the Pension Plan. Participants who terminate service prior to being eligible for retirement (*i.e.*, age 65 or age 55 with 10 years of credited service) will forfeit all accrued benefits under the SERP. The SERP provides for the vesting of all accrued benefits to those not already retirement eligible under the plan in the event of a change of control.

Mr. Touya is a resident of Europe and does not participate in the U.S. pension benefit plans, but as described below, is entitled to other pension benefits.

#### Non-U.S. Employees
Mr. Touya is entitled to certain retirement indemnity benefits in accordance with the Collective Bargaining Agreement of the French Plastics Industry ("Collective Pension"). Such benefits are based on a formula that takes salary and years of service into consideration. In addition, Mr. Touya is eligible for benefits pursuant to a supplemental pension plan available to certain French executives ("Supplemental Pension"). This plan provides participants with an annual pension compensation for life, subject to cost of living adjustments, of up to 10% of the average annual salary and bonus paid to a participant in the five years preceding retirement, the total of the amounts received by the employee according to the Collective Pension and the Supplemental Pension being subject to a ceiling equal to 55% of the average annual salary and bonus paid to a participant in the five years preceding retirement. In the event of a participant's death after retirement, the plan provides a surviving spouse with annual payments of 60% of the participant's Supplemental Pension for life. Pension benefits would normally commence at age 67, which is the legal retirement age in France, but reduced benefits are available after age 62 if the employment contract is terminated by the company after age 57.

The table below includes information relating to the defined benefit retirement plans of each NEO Assumptions used to determine the present value of accumulated benefit as of December 31, 2022 are the same as those found in Note 9, "Retirement and Deferred Compensation Plans" to Aptar's Financial Statements.

&nbsp;&nbsp;&nbsp;&nbsp;(1) In addition to the amounts reported in this column, Messrs. Tanda, Kuhn and Prieur would vest in outstanding equity awards in accordance with the retirement vesting provisions of such awards and with an estimated value of $10,683,693, $2,899,712 and $2,117,207, respectively, as of December 31, 2022. With respect to PRSUs in the case of retirement, vesting is prorated and based on actual performance through the end of the performance period (assumed to be target performance for purposes of this table).

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

&nbsp;&nbsp;&nbsp;&nbsp;(2) For RSUs deferred pursuant to the Company's annual incentive plan, in the event of a termination other than due to cause, the NEO would vest in the number of RSUs equal to his or her deferral, but would not vest in the 20% additional RSUs granted under the deferral program.

&nbsp;&nbsp;&nbsp;&nbsp;(3) For scenarios which provide for payments, this row assumes target payouts under the PRSU awards and in the case of death or disability, is prorated based on the portion of the performance periods completed as of December 31, 2022.

&nbsp;&nbsp;&nbsp;&nbsp;(4) In the event of Mr. Tanda's, Mr. Kuhn's or Ms. Gong's termination of employment other than for cause and not within two years following a change in control, the executive would remain eligible for a prorated annual bonus based on actual performance, but only if such termination occurs during the third or fourth quarter of the Company's fiscal year. Because the annual bonus is considered earned as of December 31, 2022, amounts related to the pro rata bonus have been excluded from this table and are reported in the 2022 Summary Compensation Table as 2022 compensation.

#### Normal Expiration of Employment Agreement
If his employment ends due to the expiration of the employment agreement as a result of non-renewal by the Company, Mr. Tanda is entitled to receive an amount equal to one year's base salary and his target annual performance incentive. As a condition to the employment agreements of Mr. Kuhn and Ms. Gong each would receive his/her current base salary amount as well as benefits currently provided, including current health and welfare benefits (consisting of health and term life premiums) for a period of one year following the normal expiration date of his/her agreement. Amounts would be paid and benefits would be provided on a monthly basis for twelve months The employment agreement of Mr. Touya has no expiration date. The employment of Mr. Prieur expires at the end of the month in which he reaches ordinary retirement age.

#### Voluntary or With Cause Termination
Mr. Tanda, Mr. Kuhn and Ms. Gong are not entitled to additional benefits if they are terminated with cause. With voluntary termination in the third or fourth quarter of the Company's fiscal year, Messrs. Tanda and Kuhn and Ms. Gong would remain eligible for a prorated annual bonus based on actual performance. With voluntary termination, Messrs. Touya and Prieur may receive monthly payments in accordance with the non-competition clauses of their contracts equal to 50% of their former monthly salary (and annual bonus for Mr. Prieur) for a period of two years from the date of termination. Such payments would not be made in the event of a termination with cause, generally defined as gross misconduct for Mr. Touya and as defined in accordance with Swiss law for Mr. Prieur. Equity awards granted to NEOs continue to vest upon retirement (and in the case of PRSUs pro-rated for service during the performance period). For a description of the value of outstanding equity awards as of December 31, 2022, see the second paragraph under "Involuntary or Good Reason Termination After a Change in Control" below.

#### Involuntary Termination
For Mr. Kuhn and Ms. Gong amounts shown above represent their base salaries and annual performance incentive amounts. Amounts would be paid on a monthly basis for the remaining term of each respective agreement. If Mr. Tanda is terminated without "cause," he is entitled to receive 1.5 times (i) his base salary then in effect and (ii) the greater of (x) his target annual performance incentive for the year in which he was terminated and (y) the average of the annual performance incentives paid to him for the two preceding years, paid in 18 equal installments, as well as the medical, disability and life insurance benefits he would have otherwise received for a period of 18 months following the termination date and a prorated annual bonus based on actual performance. Cash payment amounts shown for Mr. Touya represent payments that would be required under the Collective Bargaining Agreement of the French Plastics Industry, six months of his average gross salary (as defined in his employment agreement), and monthly payments in accordance with the non-competition clauses of his respective contracts equal to 50% of his former monthly salary for a period of two years from the date of termination. The Collective Bargaining Agreement of the French Plastics Industry provides for an indemnity to be paid upon involuntary termination of employment that is based on the number of years of service and on the average monthly total compensation paid during the last twelve months ("Monthly Salary"). This indemnity is equal to 4.4 times the Monthly Salary in total for the first 13 years of service plus 0.5 times the Monthly Salary for each year thereafter. No payments would be made in connection with PRSUs regarding an involuntary termination. Cash payment amounts shown for Mr. Prieur represent payments equal to six months of the base gross salary as in effect at the time of the notification of termination and the prorated average annual gross bonus received by him during the three years prior to his dismissal.

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

For Messrs. Kuhn, Prieur and Touya with respect to certain RSU awards, if they are terminated without cause or, with respect to a retiree-eligible participant, retire upon learning that they will be terminated without cause, such RSU awards vest in full immediately on the date of termination or retirement, as applicable.

#### Involuntary or Good Reason Termination After a Change in Control ("CIC")
Cash payment amounts shown for Mr. Tanda represent, according to his employment agreements and the CIC provisions therein, three times his highest annualized salary during the 12 month period preceding the termination and three times the average of his annual performance incentive amounts earned or payable in the past three fiscal years, as well as a prorated annual performance incentive. The cash payment amounts shown for Mr. Kuhn and Ms. Gong represent, according to their employment agreements and the CIC provisions therein, two and one-half times their highest annualized salary during the 12 month period preceding the termination and two and one-half times the average of their annual performance incentive amounts earned or payable in the past three fiscal years, as well as a prorated annual performance incentive. Cash payments under this scenario would be lump sum payments that would be expected to be paid within approximately 30 days following the date of termination. The employment agreement of Mr. Tanda also provides for the continuation of health and welfare benefits currently provided, for a period of three years following the date of termination. The agreements of Mr. Kuhn and Ms. Gong also provide for the continuation of health and welfare benefits currently provided, for a period of two and one-half years following the date of termination. Cash payment amounts shown for Mr. Touya are identical to the payments described above under "Involuntary Termination" in accordance with his agreements. Cash payment amounts shown for Mr. Prieur represent payments equal to his annual base salary and the average annual gross bonus received by him during the three years prior to his dismissal.

For awards granted prior to 2022, the Company's employee stock option agreements, RSU agreements, and PRSU agreements provide for the acceleration of vesting upon a CIC. Beginning with the 2022 grants, equity awards will vest in the event of a qualifying termination of employment following a change in control, with performance awards to be earned based on target performance. In the event the awards are not assumed in a change in control, the vesting of the awards will accelerate upon such change in control, with performance goals achieved at target. Because all stock options held by the NEOs were vested as of December 31, 2022, no value is included with respect to the acceleration of stock options. The PRSUs amounts are based on the closing stock price of $109.98 per share on December 30, 2022 (the "Closing Price") multiplied by the number of shares subject to the PRSU awards, assuming target performance.The accelerated RSU values included in the above table represent the Closing Price multiplied by the number of unvested RSUs. Further information regarding RSUs and PRSUs can be found under "Outstanding Equity Awards at Fiscal Year-End."

#### Disability
The employment agreements of Messrs. Tanda and Kuhn and Ms. Gong provide for payments equal to a minimum of approximately 66.67% of their base salary while they are disabled, until they reach the age of 65. A portion of the payments are covered under insurance policies paid for by the Company. The cash payment amounts included in the above table for Messrs. Tanda and Kuhn and Ms. Gong represent one year of disability payments under this scenario. In addition, the Company's employee stock option agreements, RSU agreements and PRSU agreements provide for the acceleration of vesting in the event of disability (with prorated target vesting in the case of PRSUs). Further information regarding the value of accelerated equity grants shown in the above table can be found in the preceding paragraph.

#### Death
Upon death, the employment agreements of Messrs. Tanda and Kuhn and Ms. Gong provide their estates with one-half of their annual salary that they would have received until the second anniversary of their death. The Company's employee stock option, RSU agreements and PRSU agreements provide for the acceleration of vesting in the event of death (with prorated target vesting in the case of PRSUs) and the values shown in the table above for this scenario are the same as those shown at target under the Disability scenario.

#### CIC without Termination
The NEOs are not entitled to additional benefits if there is a CIC without termination within two years of the CIC event other than the acceleration of equity award vesting for awards granted prior to 2022. In the event of a change in control as of December 31, 2022, the NEOs would accelerate with respect to their outstanding awards (other than the 2022 grants which are subject to double trigger vesting) as follows (assuming target

performance for the PRSUs): Mr. Tanda $11,392,056, Mr. Kuhn $3,244,298, Mr. Touya $3,170,172, Mr. Prieur $2,390,196, and Ms. Gong $2,655,576.

#### Non-compete Information
The agreements of Messrs. Tanda and Kuhn and Ms. Gong require that during the employment period and for one year thereafter in the case of either termination for good reason following a CIC or termination without cause, or for two years following termination for any other reason, that each executive will not (i) compete directly or indirectly with the Company or (ii) solicit employees or customers of the Company. The agreement of Messrs. Touya and Prieur requires that, for a period of two years following termination, each executive will not (i) compete directly or indirectly with the Company or (ii) solicit employees or customers of the Company, and that under this arrangement, each executive will receive monthly payments equal to 50% of his former monthly salary (and annual bonus, in the case of Mr. Prieur) for a period of two years from the date of termination. Payments would not be made to Messrs. Touya and Prieur if they were terminated with cause, defined as gross misconduct for Mr. Touya and as defined in applicable Swiss law in the case of Mr. Prieur.

#### Pension Related Benefits
Information concerning pension benefits can be found under the heading "Pension Benefits."

### CEO Pay Ratio
As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, Aptar is providing the following disclosure about the relationship of the annual total compensation of our employees to the annual total compensation of Stephan Tanda, our President and CEO. To better understand this disclosure, we think it is important to give context to our operations. As a global organization, approximately 19%, or 2,500 of our employees are located in the United States, while approximately 81% or 11,000 employees are located throughout Europe, Asia and South America. We strive to create a competitive global compensation program in terms of both the position and the geographic location in which the employee is located. As a result, our compensation program varies amongst each local market in order to allow us to provide a competitive compensation package.

#### Pay Ratio
For 2022:

● The median of the annual total compensation of all of our employees, other than Mr. Tanda, was $55,247.

● Mr. Tanda's annual total compensation was $8,840,507.

● Based on this information, the ratio of the annual total compensation of Mr. Tanda to the median of the annual total compensation of all employees is estimated to be 160 to 1.

Given the significant weight of our executive compensation program towards performance-based elements, we expect that our pay ratio disclosure will fluctuate year-to-year based on the Company's performance against the pre-established performance goals.

#### Identification of Median Employee
For purposes of the foregoing CEO pay ratio disclosure, we were required to identify the "median employee" of our worldwide workforce, without regard to their location, compensation arrangements or employment status (full-time versus part-time) and then determine the annual total compensation that "median employee" earned during 2022. The applicable SEC rules require us to identify a "median employee" only once every three years, as long as there have been no material changes in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change to our CEO pay ratio disclosure. Because there have been no material changes in our employee population or employee compensation arrangements that we believe would significantly impact the Company's CEO pay ratio disclosure, we are using the same "median employee" for our 2022 CEO Pay Ratio that we used for our 2020 CEO Pay Ratio, although we have updated the calculation of the total compensation earned by that employee for 2022. We determined our "median employee" for purposes of determining our 2022 CEO pay ratio by identifying the employee whose compensation was at the median of the compensation of our employee population (other than our CEO) for 2020.

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

For the 2020 pay ratio, we used the following methodology:

&nbsp;&nbsp;&nbsp;&nbsp;(1) We selected December 31, 2020 as the date on which to determine our median employee.

&nbsp;&nbsp;&nbsp;&nbsp;(2) As of that date, we had had approximately 12,000 employees, with approximately 2,400 employees based in the United States and 9,600 employees located outside of the United States. We applied the allowed "de minimis" exception to exclude 524 employees in the following countries: India (314); Indonesia (106); and Russia (104). If we excluded any employees from a country using this de minimis exception, all employees from that country were excluded. After taking into account the de minimis exemption, approximately 2,400 employees in the United States and approximately 9,076 employees located outside of the United States were considered for identifying the median employee.

&nbsp;&nbsp;&nbsp;&nbsp;(3) For purposes of identifying the median employee from our employee population base, we considered the total cash compensation earned by our employees, as compiled from our payroll records. We selected total cash compensation as it reflects the principal forms of compensation delivered to all of our employees and this information is readily available in each country. In addition, we measured compensation for purposes of determining the median employee using the 12 month period ended December 31, 2020. Compensation paid in foreign currencies was converted to U.S. dollars using the average exchange rate at December 31, 2020.

&nbsp;&nbsp;&nbsp;&nbsp;(4) In determining the annual total compensation of the median employee, such employee's compensation was calculated in accordance with Item 402(c)(2)(x) of Regulation S-K, as required pursuant to the SEC executive compensation disclosure rules.

### Pay Versus Performance
Pursuant to Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(v) of Regulation S-K, the Pay Versus Performance Table (set forth below) is required to include "compensation actually paid," as calculated per SEC disclosure rules, to the Company's principal executive officer ("PEO") and the Company's non-PEO NEOs, as noted below. "Compensation actually paid" represents a new required calculation of compensation that differs significantly from the Summary Compensation Table calculation of compensation, the NEO's realized or earned compensation, as well as from the way in which the Management Development and Compensation Committee views annual compensation decisions, as discussed in the Compensation Discussion and Analysis. The amounts in the table below are calculated in accordance with SEC rules and do not represent amounts actually earned or realized by NEOs, including with respect to RSUs and PRSUs which remain subject to forfeiture if the vesting conditions are not satisfied.

performance. ROIC is defined as adjusted earnings before interest and taxes at the effective tax rate, divided by average equity plus average debt.

*Relationship Between Pay and Performance*

We believe the "compensation actually paid" in each of the years reported above and over the three-year cumulative period are reflective of the Management Development and Compensation Committee's emphasis on "pay-for-performance" as the "compensation actually paid" fluctuated year-over-year, primarily due to the result of our stock performance and our varying levels of achievement against pre-established performance goals under our 2022 STI and 2022 LTI awards, including our ROIC performance. Because of our significant emphasis on equity awards, which represented 68% and 51% of the 2022 target pay of our CEO and the other NEOs (on average), respectively, our "compensation actually paid" is most directly impacted by our stock price performance.

The following is a list of financial performance measures, which in the Company's assessment represent the most important financial performance measures used by the Company to link "compensation actually paid" to the NEOs for 2022. Please see the Compensation Discussion & Analysis for further information regarding these measures and how they were used in the 2022 executive compensation program.

● STI Adjusted EBITDA Growth, measured on a Corporate basis for each of the NEOs as well as a segment basis for Messrs. Touya and Prieur and Ms. Gong

● Core Sales Growth, measured on a Corporate basis for each of the NEOs as well as a segment basis for Messrs. Touya and Prieur and Ms. Gong

● Adjusted Return on Invested Capital

● Relative Total Shareholder Return

## Transactions with Related Persons
Aptar or one of our subsidiaries may occasionally enter into transactions with certain "related persons." Related persons include our executive officers, directors, nominees for directors, a beneficial owner of more than 5% of our common stock and immediate family members of these persons. We refer to transactions involving amounts in excess of $120,000 and in which the related person has a direct or indirect material interest as "related person transactions." Each related person transaction must be approved in accordance with Aptar's written Related Person Transactions Policy by the Audit Committee of the Board of Directors. Each member of the Audit Committee is considered a "disinterested" director and therefore are approving related person transactions from this perspective.

The Audit Committee considers all relevant factors when determining whether to approve a related person transaction including, without limitation, the following:

● the size of the transaction and the amount payable to a related person;

● the nature of the interest of the related person in the transaction;

● whether the transaction may involve a conflict of interest; and

● whether the transaction is on terms that would be available in comparable transactions with unaffiliated third parties.

The following are not considered related person transactions:

● executive officer or director compensation which has been approved by the Management Development and Compensation Committee of the Board of Directors;

● indebtedness incurred with a beneficial owner of more than 5% of any class of voting securities of the Company;

● indebtedness incurred for the purchase of goods or services subject to usual trade terms, for ordinary business travel and expense payments, and for other transactions in the ordinary course of business; and

● any transaction in which a person is deemed a Related Person solely on the basis of such person's equity ownership and all holders of that class of equity receive the same benefit on a pro rata basis.

Pursuant to this policy, the Audit Committee approves all related person transactions, including those involving NEOs and directors. Since January 1, 2022, there have been no related person transactions for which disclosure is required under SEC rules.

## Audit Committee Report
Management is responsible for Aptar's internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of Aptar's consolidated financial statements in accordance with generally accepted auditing standards, including the effectiveness of internal controls, and issuing a report thereon. The Audit Committee's responsibility is to assist the Board in fulfilling its responsibility for overseeing the quality and integrity of the accounting, auditing and financial reporting practices of Aptar.

During the course of the fiscal year ended December 31, 2022, management completed the documentation, testing and evaluation of the Company's system of internal control over financial reporting in response to the requirements set forth in Section 404 of the Sarbanes-Oxley Act of 2002 and related regulations. Management and the independent registered public accounting firm kept the Audit Committee apprised of the progress of the documentation, testing and evaluation through periodic updates, and the Audit Committee provided advice to management during this process.

The Audit Committee has reviewed and discussed the audited consolidated financial statements with management and the independent registered public accounting firm. Management has represented to the Audit Committee that the audited consolidated financial statements were prepared in accordance with generally accepted accounting principles. Also, the Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board ("PCAOB") and the SEC.

In addition, the Audit Committee has received the written disclosures and letter from the independent registered public accounting firm as required by the PCAOB regarding the independent registered public accounting firm's communication with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm its independence from Aptar and Aptar's management. In considering the independence of Aptar's independent registered public accounting firm, the Audit Committee took into consideration the amount and nature of the fees paid to this firm for non-audit services as described under "Proposal 5—Ratification of the Appointment of PricewaterhouseCoopers LLP as the Independent Registered Public Accounting Firm for 2023".

Based on the review and discussions referred to above, the Audit Committee recommended to the Board of Directors, and the Board has approved, that the audited consolidated financial statements be included in Aptar's Annual Report on Form 10-K for the year ended December 31, 2022, for filing with the SEC.

### What is a quorum?
A "quorum" is the presence at the meeting, virtually via webcast or represented by proxy, of the holders of a majority of the outstanding shares of Aptar's common stock at the close of business on March 10, 2023. There must be a quorum for the meeting to be held.

### How are shares in a 401(k) plan voted?
If you hold shares of Aptar through your 401(k) plan, you will be instructing the trustee how to vote your shares by voting by Internet or by telephone, or by completing and returning the proxy card. If you do not vote by Internet or telephone or if you do not return the proxy card, or if you return it with unclear voting instructions, the trustee will not vote the shares in your 401(k) plan.

### How are shares held in a broker account voted?
If you own shares through a broker, you should be contacted by your broker regarding a proxy card and whether telephone or Internet voting options are available. If you do not instruct your broker on how to vote your shares, your broker, as the registered holder of your shares, may represent your shares at the annual meeting for purposes of determining a quorum. Even without instructions, your broker may exercise discretion in voting for the ratification of the appointment of the independent registered public accounting firm. Brokers have authority to vote in their discretion on "routine" matters if they do not receive voting instructions from the beneficial owner of the shares.

Other than the proposal regarding the ratification of the independent registered public accounting firm, all other proposals are not considered "routine" matters and, as a result, brokers may not vote on behalf of their clients if no voting instructions have been furnished. Broker non-votes are counted as shares present in determining whether the quorum requirement is satisfied but do not affect the outcome of whether a matter is approved.

### How many votes are required to approve each proposal?
In order to be elected, a director nominee must receive the affirmative vote of a majority of the votes cast present virtually via webcast or represented by proxy at the meeting and entitled to vote on the election of directors. Stockholders do not have a right to cumulate their votes for the election of directors. Abstaining will not affect the outcome of director elections. With respect to the proposal regarding the frequency of the advisory vote on executive compensation, the option receiving the greatest number of votes will be considered the frequency recommended by the Company's stockholders. Abstaining will not affect the outcome of this proposal. The approval of each other proposal requires the affirmative vote of a majority of the shares present virtually via webcast or represented by proxy at the meeting and entitled to vote on these proposals. Abstaining is the legal equivalent of voting against these proposals.

### Who will count the votes?
Our agent, Broadridge Financial Solutions, Inc., will count the votes cast by proxy or virtually via webcast during the annual meeting.

### How can I help reduce the environmental impact of the annual meeting?
We encourage you to choose electronic (e-mail) delivery of future annual meeting materials by contacting your broker or emailing us at investorrelations@aptar.com. You may also visit www.proxyvote.com and follow the Vote By Internet instructions on the proxy card or the Notice to be provided with the opportunity to choose electronic delivery for future meeting materials.

Notwithstanding the foregoing, except for any adjustment pursuant to Section 7(b) or in connection with a Change in Control, neither the Board of Directors nor the Committee shall without the approval of stockholders (i) amend the terms of outstanding Awards to reduce the exercise price of outstanding stock options or SARs, (ii) cancel outstanding stock options or SARs in exchange for cash, other Awards or stock options or SARs with an exercise price that is less than the exercise price of the original stock options or SARs, or (iii) take any other action with respect to a stock option or SAR that would be treated as a repricing under the rules and regulations of the New York Stock Exchange.

The Committee's determinations on matters within its authority shall be final, binding and conclusive. The Committee may delegate some or all of its power and authority hereunder to the Board of Directors (or any members thereof) or, subject to applicable law, to a subcommittee of the Board of Directors, a member of the Board of Directors, the Chief Executive Officer or other executive officer of the Company as the Committee deems appropriate; provided, however, that the Committee may not delegate its power and authority to a member of the Board of Directors, the Chief Executive Officer or other executive officer of the Company with regard to the selection for participation in this Plan of an officer, director or other person subject to Section 16 of the Exchange Act or decisions concerning the timing, pricing or amount of an Award to such an officer, director or other person.

No member of the Board of Directors or Committee, and neither the Chief Executive Officer nor any other executive officer to whom the Committee delegates any of its power and authority hereunder, shall be liable for any act, omission, interpretation, construction or determination made in connection with this Plan in good faith, and the members of the Board of Directors and the Committee and the Chief Executive Officer or other executive officer shall be entitled to indemnification and reimbursement by the Company in respect of any claim, loss, damage or expense (including attorneys' fees) arising therefrom to the full extent permitted by law (except as otherwise may be provided in the Company's Certificate of Incorporation and/or By-laws) and under any directors' and officers' liability insurance that may be in effect from time to time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.** **Shares Subject to Plan** Subject to adjustment as provided in Section 7(b) and to all other limits set forth in this Plan, the number of shares of Common Stock that shall initially be available for all Awards under this Plan shall be 3,250,000 (reduced by the number of shares of Common Stock subject to awards granted under the Prior Plan on or after March 31, 2018), all of which may be issued under the Plan in connection with ISOs (as defined in Section 6(a)). The number of shares of Common Stock that remain available for future grants under the Plan shall be reduced by the sum of the aggregate number of shares of Common Stock which become subject to Awards. To the extent that shares of Common Stock subject to an outstanding award granted under either this Plan or a Prior Plan are not issued or delivered by reason of (i) the expiration, termination, cancellation or forfeiture of such award (except in the case of an option to the extent shares of Common Stock are issued or delivered by the Company in connection with the exercise of a tandem SAR) or (ii) the cash settlement of such award, then such shares of Common Stock shall again be available under this Plan. Shares of Common Stock shall not again be available under the Plan (i) if tendered to satisfy all or a portion of tax withholding obligations relating to such Award, (ii) if such shares were subject to an option or stock-settled SAR and were not issued or delivered upon the net settlement or net exercise of such option of SARs (iii) if withheld to pay the exercise price of stock options or SARs awarded hereunder or (iv) if repurchased by the

Company on the open market with the proceeds of an option exercise. The number of shares that again become available pursuant to this paragraph shall be equal to one share for each share subject to an Award described herein; provided, however, any shares from a Prior Plan that become available under this Plan pursuant to this paragraph shall be added to this Plan based on the share deduction ratio set forth in such Prior Plan. At the time this Plan becomes effective, none of the shares of Common Stock available for future grant under any Prior Plan shall be available for grant under such Prior Plan.

The number of shares of Common Stock available for Awards under this Plan shall not be reduced by (i) the number of shares of Common Stock subject to Substitute Awards or (ii) available shares under a stockholder approved plan of a company or other entity which was a party to a corporate transaction with the Company (as appropriately adjusted to reflect such corporate transaction) which become subject to Awards granted under this Plan (subject to applicable stock exchange requirements).

The aggregate value of cash compensation and the grant date fair value of shares of Common Stock that may be awarded or granted during any fiscal year of the Company to any non-employee director shall not exceed $500,000; provided, however, that the limit set forth in this sentence shall be multiplied by two in the year in which a non-employee director commences service on the Board of Directors. Shares of Common Stock available under the Plan may be treasury shares reacquired by the Company or authorized and unissued shares, or a combination of both.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. **Eligibility** Participants in this Plan shall consist of such employees, non-employee directors, consultants, independent contractors and agents and persons expected to become employees, non-employee directors, consultants, independent contractors and agents of the Company and its Affiliates as the Committee in its sole discretion may select from time to time. The Committee's selection of a person to participate in this Plan at any time shall not require the Committee to select such person to participate in this Plan at any other time. Except as provided otherwise in an Award agreement, for purposes of this Plan, references to employment by the Company shall also mean employment by an Affiliate, and references to employment shall include service as a non-employee director, consultant, independent contractor or agent. The Committee shall determine, in its sole discretion, the extent to which a participant shall be considered employed during any periods during which such participant is on a leave of absence.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**6.** **Awards** The Committee may grant to eligible employees, non-employee directors, consultants, independent contractors and agents, in accordance with this Section 6 and the other provisions of the Plan, stock options, stock appreciation rights (" SARs "), restricted stock and restricted stock units (each, an " Award " and, collectively, the " Awards ").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Options .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. Options granted under the Plan may be incentive stock options (" ISOs ") within the meaning of Section 422 of the Code or any successor provision, or nonqualified stock options, as the Committee may determine; except that, so long as so provided in such Section 422, no ISO may be granted under the Plan to any employee of an Affiliate which is not a subsidiary corporation (as such term is used in subsection (b) of Section 422 of the Code) of the Company or any non-employee director, consultant, independent contractor or agent. To the extent that the aggregate Market Value (determined as of the date of grant) of shares of Common Stock with respect to which options designated as ISOs are exercisable for the first time by a participant during any calendar year (under this Plan or any other plan of the Company, or any parent or subsidiary) exceeds the amount (currently $100,000) established by the Code, such options shall constitute nonqualified stock options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. The option price per share of Common Stock shall be fixed by the Committee at not less than 100% of Market Value on the date of the grant; provided that if an ISO is granted to any person who, at the time such option is granted, owns capital stock possessing more than 10 percent of the total combined voting power of all classes of capital stock of the Company (or of any parent or subsidiary) (a " Ten Percent Holder "), the purchase price per share of Common Stock shall not be less than the price (currently 110% of Market Value) required by the Code in order to constitute an ISO. Notwithstanding the foregoing, in the case of an option that is a Substitute Award, the purchase price per share of the shares subject to such option may be less than 100% of the Market Value per share on the date of grant, provided , that the excess of: (a) the aggregate Market Value (as of the date such Substitute Award is granted) of the shares subject to the Substitute Award, over (b) the aggregate purchase price thereof does not exceed the excess of: (x) the aggregate market value (as of the time immediately preceding the transaction giving rise to the Substitute Award, such market value to be determined by the Committee) of the shares of the predecessor company or other entity that were subject to the grant assumed or substituted for by the Company, over (y) the aggregate purchase price of such shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Subject to the minimum vesting requirements of Section 6(e) , each option shall be exercisable at such time or times as the Committee shall determine at grant, provided that no option shall be exercised later than 10 years after its date of grant; provided that if an ISO shall be granted to a Ten Percent Holder, such option shall not be exercised later than five years after its date of grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. An option may be exercised (i) by giving written notice to the Company specifying the number of whole shares of Common Stock to be purchased and accompanied by payment therefor in full (or arrangement made for such payment to the Company's satisfaction) either (A) in cash, (B) in cash delivered by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise, (C) by delivery of previously owned whole shares of Common Stock (for which the optionee has good title, free and clear of all liens and encumbrances) having a Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable by reason of such exercise, (D) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered upon exercise of the option having an aggregate Market Value, determined as of the date of exercise, equal to the aggregate purchase price payable by reason of such exercise, or (E) a combination of (A), (C) and (D), in each case to the extent set forth in the agreement relating to the option, (ii) by executing such documents as the Company may reasonably request and (iii) if applicable, by surrendering to the Company any tandem SARs which are cancelled by reason of the exercise of the option. The Committee shall have sole discretion to disapprove of an election pursuant to clauses (B), (C), (D) or (E), except that the Committee may not disapprove of an election made by a participant subject to Section 16 of the Exchange Act. No shares of Common Stock shall be issued or delivered until the full purchase price therefore and any withholding taxes have been paid (or arrangement made for such payment to the Company's satisfaction). No dividends, or dividend equivalents, shall be paid on any options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e. Except as otherwise provided by the Committee at the time of grant or otherwise, upon a termination of employment for any reason during the vesting period the portion of the option still subject to vesting provisions shall be forfeited by the participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) SARs .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. An SAR shall entitle its holder to receive from the Company, at the time of exercise or settlement of such right, an amount equal to the excess of Market Value (at the date of exercise) over a base price fixed by the Committee multiplied by the number of SARs which the holder is exercising or which are being settled. SARs may be tandem with any previously or contemporaneously granted option or independent of any option. The base price of a tandem SAR shall be the option price of the related option. The base price of an independent SAR shall be fixed by the Committee at not less than 100% of the Market Value of a share of Common Stock on the date of grant of the SAR. The amount payable may be paid by the Company in Common Stock (valued at its Market Value on the date of exercise) or, to the extent provided in the Award agreement, cash or a combination thereof. No dividends, or dividend equivalents, shall be paid on any SAR. Notwithstanding the foregoing, in the case of an SAR that is a Substitute Award, the base price per share of the shares subject to such SAR may be less than 100% of the Market Value per share on the date of grant, *provided*, that the excess of: (a) the aggregate Market Value (as of the date such Substitute Award is granted) of the shares subject to the Substitute Award, over (b) the aggregate base price thereof does not exceed the excess of: (x) the aggregate market value (as of the time immediately preceding the transaction giving rise to the Substitute Award, such market value to be determined by the Committee) of the shares of the predecessor company or other entity that were subject to the grant assumed or substituted for by the Company, over (y) the aggregate base price of such shares.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Subject to the minimum vesting requirements of Section 6(e) , each SAR shall be exercisable at such time or times as the Committee shall determine at grant, provided that no SAR shall be exercised later than 10 years after its date of grant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. An SAR may be exercised (i) by giving written notice to the Company specifying the number of whole SARs then being exercised and (ii) by executing such documents as the Company may reasonably request. To the extent a tandem SAR is exercised or settled, the related option will be cancelled and to the extent the related option is exercised, the tandem SAR will be cancelled.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. Except as otherwise provided by the Committee at the time of grant or otherwise, upon a termination of employment for any reason during the vesting period the portion of the SAR still subject to vesting provisions shall be forfeited by the participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Restricted Stock .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The Committee may award to any participant shares of Common Stock, subject to this Section 6(c) and such other terms and conditions as the Committee may prescribe (such shares being called " restricted stock "). During the restriction period, the shares of restricted stock shall be held by a custodian in book entry form with restrictions on such shares duly noted or, alternatively, a certificate or certificates for restricted stock shall be registered in the name of the participant or a nominee of the Company and deposited, together with a stock power endorsed in blank if requested by the Company, with the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Subject to the minimum vesting requirements of Section 6(e) , there shall be established for each restricted stock Award a restriction period (the " restriction period ") of such length as shall be determined by the Committee. A restricted stock Award may be subject to such other conditions to vesting, including performance goals, as the Committee shall establish. Shares of restricted stock may not be sold, assigned, transferred, pledged or otherwise encumbered, except as hereinafter provided, during the restriction period. Except for such restrictions on transfer and such other restrictions as the Committee may impose, the participant shall have all the rights of a holder of Common Stock as to such restricted stock; provided , however , that any distributions, including regular cash dividends, payable on the Common Stock during the restriction period or the performance period, as the case may be, shall be subject to the same restrictions as the shares of restricted stock with respect to which such distribution was made. Upon the lapse of all restrictions on a restricted stock Award, the Company shall remove the restrictions on any shares held in book entry form pursuant to Section 6(c)a or deliver to the participant (or the participant's legal representative or designated beneficiary) the certificates deposited pursuant to Section 6(c)a .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Except as otherwise provided by the Committee at the time of grant or otherwise, upon a termination of employment for any reason during the restriction period all shares still subject to restriction shall be forfeited by the participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Restricted Stock Units .

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a. The Committee may award to any participant restricted stock units (" restricted stock units "), subject to this Section 6(d) and such other terms and conditions as the Committee may prescribe. Upon termination of the restrictions related thereto, each restricted stock unit shall be converted into one share of Common Stock or, in lieu thereof and to the extent provided in the applicable Award agreement, the Market Value of such share of Common Stock in cash.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b. Subject to the minimum vesting requirements of Section 6(e) , there shall be established for each restricted stock unit Award a restriction period (the " restricted stock unit restriction period ") of such length as shall be determined by the Committee. A restricted stock unit Award may be subject to such other conditions to vesting, including performance goals, as the Committee shall establish. Restricted stock units may not be sold, assigned, transferred, pledged or otherwise encumbered, except as hereinafter provided, during the restricted stock unit restriction period. Upon the lapse of all restrictions on a restricted stock unit Award, each restricted stock unit shall be settled by delivery of one share of Common Stock (or, to the extent provided for in the applicable Award agreement, cash) and, if applicable, the Company shall deliver to the participant (or the participant's legal representative or designated beneficiary) the certificates representing the number of shares of Common Stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c. Prior to the settlement of a restricted stock unit Award in shares of Common Stock, the holder of such Award shall have no rights as a stockholder of the Company with respect to the shares of Common Stock subject to such Award. Holders of restricted stock units shall be entitled to dividend equivalents, if determined by the Committee; provided, however, any dividend equivalents shall be subject to the same vesting conditions applicable to the underlying restricted stock unit Award.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d. Except as otherwise provided by the Committee at the time of grant or otherwise, upon a termination of employment for any reason during the restricted stock unit restriction period all restricted stock units still subject to restrictions shall be forfeited by the participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Minimum Vesting and Performance Period Requirements . The Committee shall determine the vesting schedule and performance period, if applicable, for each Award; provided that no Award shall become exercisable or vested prior to the one-year anniversary of the date of grant and no performance period shall be less than one (1) year; provided , however , that, such restrictions shall not apply to Awards granted under this Plan with respect to the number of shares of Common Stock which, in the aggregate, does not exceed five percent (5%) of the total number of shares available for Awards under this Plan. Notwithstanding the foregoing, the Board of Directors or Committee may provide that all or a portion of the shares subject to such Award shall vest immediately upon a Change in Control or may provide in any agreement relating to an Award that upon termination without cause, constructive discharge or termination due to death, disability, retirement or otherwise, an Award shall vest immediately or, alternatively, continue to vest in accordance with the vesting schedule but without regard to the requirement for continued employment or service only.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Deferral of Awards . To the extent permitted by Section 409A of the Code, the Committee may determine that the delivery of shares of Common Stock or the payment of cash, or a combination thereof, upon the exercise or settlement of all or a portion of any Award (other than Awards of ISOs, stock options and SARs) made hereunder shall be deferred, or the Committee may, in its sole discretion, approve deferral elections made by holders of Awards. Deferrals shall be for such periods and upon such terms as the Committee may determine in its sole discretion, subject to the requirements of Section 409A of the Code. Payment of deferred amounts may be in cash, Common Stock or a combination thereof, as the Committee may determine. Deferred amounts shall be considered an Award under the Plan. The Committee may establish a trust or trusts to hold deferred amounts or any portion thereof for the benefit of participants.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Surrender . If so provided by the Committee at the time of grant, an Award may be surrendered to the Company on such terms and conditions, and for such consideration, as the Committee shall determine.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**7.** **Miscellaneous Provisions** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Nontransferability . No Award under the Plan shall be transferable other than (i) by will or the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company or (ii) a transfer of stock options without value to a "family member" (as defined in Form S-8) if approved by the Committee. Except to the extent permitted by the foregoing sentence, each Award may be exercised or received during the participant's lifetime only by the participant or the participant's legal representative or similar person. Except as permitted by the second preceding sentence, no Award shall be sold, transferred, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) or be subject to execution, attachment or similar process. Upon any attempt to so sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of any Award, such Award and all rights thereunder shall immediately become null and void. For the sake of clarity, no Award may be transferred by a participant for value or consideration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Adjustments . In the event of any equity restructuring (within the meaning of Financial Accounting Standards Board Accounting Standards Codification Topic 718, Compensation—Stock Compensation) that causes the per share value of shares of Common Stock to change, such as a share dividend, stock split, spinoff, rights offering or recapitalization through an extraordinary cash dividend, the number and class of securities available under this Plan, the terms of each outstanding stock option and SAR (including the number and class of securities subject to each outstanding stock option or SAR and the purchase price or base price per share) and the terms of each outstanding restricted stock Award and restricted stock unit Award (including the number and class of securities subject thereto) shall be appropriately adjusted by the Committee, such adjustments to be made in the case of outstanding stock options and SARs without an increase in the aggregate purchase price or base price and in accordance with Section 409A of the Code. In the event of any other change in corporate capitalization, including a merger, consolidation, reorganization, or partial or complete liquidation of the Company, such equitable adjustments described in the foregoing sentence may be made as determined to be appropriate and equitable by the Committee to prevent dilution or enlargement of rights of participants. In either case, the decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Tax Withholding . The Company shall have the right to require, prior to the issuance or delivery of any shares of Common Stock or the payment of any cash pursuant to an Award, payment by the holder of such Award of any Federal, state, local or other taxes which may be required to be withheld or paid in connection with such Award. An agreement relating to an Award may provide that (1) the Company shall withhold cash or whole shares of Common Stock which would otherwise be delivered upon exercise or settlement of the Award having, in the case of Common Stock, an aggregate Market Value determined as of the date the obligation to withhold or pay taxes arises in connection with the Award (the " Tax Date ") in the amount necessary to satisfy any such obligation or (2) the holder of the Award may satisfy any such obligation by any of the following means: (i) a cash payment to the Company; (ii) in the case of an option, a cash payment by a broker-dealer acceptable to the Company to whom the optionee has submitted an irrevocable notice of exercise; (iii) delivery to the Company of previously owned whole shares of Common Stock (for which the holder has good title, free and clear of all liens and encumbrances) having an aggregate Market Value determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation; (iv) authorizing the Company to withhold whole shares of Common Stock which would otherwise be delivered upon exercise or settlement of the Award having an aggregate Market Value determined as of the Tax Date, equal to the amount necessary to satisfy any such obligation; or (v) any combination of (i), (iii) and (iv), in each case to the extent set forth in the agreement relating to the Award; provided , however , that the Committee shall have sole discretion to disapprove of an election pursuant to clauses (ii) through (v), except that the Committee may not disapprove of an election made by a participant subject to Section 16 of the Exchange Act. Shares of Common Stock to be delivered or withheld may not have an aggregate Market Value in excess of the amount determined by applying the minimum statutory withholding rate (or, if permitted by the Company, such other rate as will not cause adverse accounting consequences under the accounting rules then in effect, and is permitted under applicable Internal Revenue Service withholding rules). Any fraction of a share of Common Stock which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by the holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Listing and Legal Compliance . The Committee may suspend the exercise or payment of any Award if it determines that securities exchange listing or registration or qualification under any securities laws is required in connection therewith and has not been completed on terms acceptable to the Committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Beneficiary Designation . To the extent permitted by the Company, participants may name, from time to time, beneficiaries (who may be named contingently or successively) to whom benefits under the Plan are to be paid in the event of their death before they receive any or all of such benefits. Each designation will revoke all prior designations by the same participant, shall be in a form prescribed by the Company, and will be effective only when filed by the participant in writing with the Company during the participant's lifetime. In the absence of any such designation, benefits remaining unpaid at a participant's death shall be paid to the participant's estate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Rights of Participants . Nothing in the Plan shall interfere with or limit in any way the right of the Company or any Affiliate to terminate any participant's employment or service at any time, nor confer upon any participant any right to continue in the employ or service of the Company or any Affiliate for any period of time or to continue his or her present or any other rate of compensation. No individual shall have a right to be selected as a participant, or, having been so selected, to be selected again as a participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Foreign Employees . Without amending this Plan, the Committee may grant Awards to eligible persons who are foreign nationals and/or reside outside the U.S. on such terms and conditions different from those specified in this Plan as may in the judgment of the Committee be necessary or desirable to foster and promote achievement of the purposes of this Plan and, in furtherance of such purposes the Committee may make such modifications, amendments, procedures, subplans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Affiliates operates or has employees.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Amendment . The Committee may amend the Plan as it shall deem advisable, subject to any requirement of stockholder approval required by applicable law, rule or regulation. No amendment may materially impair the rights of a holder of an outstanding Award without the consent of such holder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) Governing Law .
