#### Cautionary Statements Regarding Forward-Looking Information
Information included or incorporated by reference in Magnera Corporation's filings with the U.S. Securities and Exchange Commission (the "SEC") and press releases or other public statements contains or may contain "forward-looking" statements within the meaning of the federal securities laws and are presented pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. Such "forward-looking" statements include, but are not limited to, statements with respect to our financial condition, results of operations and business, our expectations or beliefs concerning future events, including future financial and operating results, objectives, expectations and intentions, and other statements that are not historical facts. These statements contain words such as "believes," "expects," "may," "will," "should," "would," "could," "seeks," "approximately," "intends," "plans," "estimates," "projects," "outlook," "anticipates" or "looking forward" or similar expressions that relate to our strategy, plans, intentions, or expectations. All statements we make relating to our estimated and projected earnings, margins, costs, expenditures, cash flows, growth rates, and financial results or to our expectations regarding future industry trends are forward-looking statements. In addition, we, through our senior management, from time to time make forward-looking public statements concerning our expected future operations and performance and other developments. These forward-looking statements are based upon the current beliefs and expectations of the management and are subject to risks and uncertainties that may change at any time, and, therefore, our actual results may differ materially from those that we expected. These risks, uncertainties, and other unpredictable or uncontrollable factors include, but are not limited to, those described herein; in Part I, "Item 1A. Risk Factors," and under the heading "Forward-Looking Statements" and in other sections of the Company's Annual Report on Form 10-K for the fiscal year ended September 27, 2025 (the "2025 Form 10-K") filed with the SEC; and in its other filings with the SEC, all of which are available on the SEC's website at www.sec.gov.

Additionally, the forward-looking matters discussed in this proxy statement may not occur and readers are cautioned not to place undue reliance on such forward-looking statements. All forward-looking statements are made only as of the date hereof, and we undertake no obligation to publicly update or revise any forward-looking statement as a result of new information, future events or otherwise, except as otherwise required by law.

#### Compensation Highlights
The Compensation Committee designs compensation programs that reflect the Company's financial performance and are market-competitive based on a person's responsibilities, individual performance, and ability to exemplify the Company's purpose, promise, and beliefs. The objectives of our executive compensation programs are to attract, retain, motivate, and reward executives crucial to achieving the Company's near-term operating plan and long-term growth, thereby creating shareholder value.

Our compensation programs are organized around three principles:

---

| | | |

| **Pay for Performance** | **Pay at Risk** | **Shareholder Alignment**  |
| Reward achievement <br>of financial outcomes that <br>increase shareholder <br>value | Provide a mix of <br>compensation with strong <br>emphasis on short- and <br>long-term incentives tied to the Company's <br>financial performance | Require executives to <br>own a meaningful <br>personal stake in the <br>Company |

---

Total compensation for our executives consists of:

---

| | | | | |
|:---|:---|:---|:---|:---|
| &nbsp;&nbsp;**Base** <br>**Salary** | • Fixed Cash | **Short-Term Incentive** | • Cash Bonus for achievement of the annual operating plan  | • Cash Bonus for achievement of the annual operating plan  |
| &nbsp;&nbsp;**Long-Term** <br>**Incentive** | • Equity awards tied to long-term performance and stock price growth<br>• Performance Stock Units<br>• Restricted Stock Units<br>| **Benefits** | • Retirement Savings<br>• Health & Welfare Benefits<br>| • Severance<br>• Minimal Perquisites<br>|

#### Election of Directors
The Board currently consists of nine directors, each of whom is standing for re-election at the Annual Meeting and each of whom is named in this proxy statement. The Company's shareholders will vote on the election of the following nine director nominees to serve on the Board for one-year terms expiring on the date of the 2027 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified:

---

| | | |
|:---|:---|:---|
| Curtis L. Begle | Thomas M. Fahnemann | Samantha J. Marnick  |
| Bruce Brown  | Kevin M. Fogarty | C. Rick Rickertsen  |
| Michael S. Curless  | Mary D. Hall | Thomas E. Salmon |

---

Each director nominee has consented to serve if re-elected to the Board. If at the time of the Annual Meeting a director nominee is unable to serve, an event we do not anticipate, the Proxy Holders (as defined in the "Frequently Asked Questions" section of this proxy statement) will vote for a substitute director nominee as may be designated by the Board, unless the Board elects to reduce the size of the Board accordingly or has not yet identified a replacement nominee.

#### The Board recommends a vote " FOR " each of the nine director nominees.

#### Ratification of Appointment of Independent Registered Public Accounting Firm
The Audit Committee of the Board appointed Ernst & Young LLP ("EY") as the Company's independent registered public accounting firm for the fiscal year ending September 26, 2026. EY audited the Company's consolidated financial statements for the fiscal year ended September 27, 2025.

Although shareholder ratification is not required by our organizational documents or applicable law, the Board believes it is a sound corporate governance practice to seek shareholder ratification of the appointment of EY. In the event EY's appointment is not ratified, the Audit Committee will reconsider whether it is appropriate to select another independent registered public accounting firm but is not required to do so. Even if EY's appointment is ratified, the Audit Committee, in its discretion, may select a different registered public accounting firm at any time during the year if the Audit Committee determines that such a change would be in the best interests of the Company and its shareholders.

An EY representative is expected to virtually attend the Annual Meeting. The representative will have an opportunity to make a statement at the Annual Meeting, if he or she desires to do so, and is expected to be available to respond to appropriate shareholder questions.

#### The Board and the Audit Committee recommend a vote " FOR " ratification of the appointment of EY as the

#### Company's independent registered public accounting firm for the fiscal year ending September 26, 2026.

#### Independent Registered Public Accountant Fees
The following table sets forth the fees (in millions) incurred by EY for the fiscal year ending September 27, 2025, for various categories of professional services it performed as our independent registered public accounting firm.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes annual financial statement and limited quarterly review services, statutory audits of foreign subsidiaries and providing consents for Securities and Exchange Commission filings and other services that are normally provided by the independent registered public accountants in connection with securities offerings.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Includes merger and acquisition due diligence and other attest or accounting services.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Includes domestic and international tax compliance, planning services and tax advice.

The Audit Committee's Charter provides for the pre-approval of audit and non-audit services performed by the Company's independent auditors and any other accounting firms. The Audit Committee may delegate this authority in writing to one or more of its members, and in such case, the member(s) to whom such authority is delegated must report their decisions to the Audit Committee at its next scheduled meeting.

The Audit Committee approved all audit fees and audit-related fees incurred by EY during fiscal year 2025. All services performed for the Company by EY were permissible under applicable laws and regulations.

#### Change of Independent Registered Public Accountant
On the closing date of the Transaction, and in connection with the Transaction, following the conclusion of an evaluation managed by the Audit Committee, the Audit Committee approved the engagement of EY as the Company's new independent registered public accounting firm for the fiscal year ending September 27, 2025.

During the fiscal years ended December 31, 2023 and 2022, and the subsequent interim period through November 4, 2024, neither the Company nor anyone acting on its behalf consulted with EY with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's consolidated financial statements, which were audited by Deloitte & Touche LLP ("Deloitte"), and neither a written report nor oral advice was provided to the Company by EY that EY concluded was an important factor considered by the Company in reaching a decision on any accounting, auditing, or financial reporting issue, or (ii) any matter subject to any "disagreement" (as such term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a "reportable event" (as such term is defined in Item 304(a)(1)(v) of Regulation S-K).

In connection with the appointment of EY, on November 4, 2024, the Audit Committee approved the dismissal of Deloitte as the Company's independent registered public accounting firm, effective immediately.

The audit report of Deloitte on the Company's consolidated financial statements for the two most recent fiscal years ended December 31, 2023 and 2022 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles.

In connection with the audit of the Company's consolidated financial statements for the fiscal years ended December 31, 2023 and 2022, and the subsequent interim period through November 4, 2024, there were no (i) "disagreements" (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference to the subject matter of the disagreement in their reports on the financial statements for such years, or (ii) "reportable events" (as defined in Item 304(a)(1)(v) of Regulation S-K).

#### Advisory Approval of Named Executive Officer Compensation ("Say-on-Pay" Vote)
Executive compensation is an important topic for our shareholders. We have designed our executive compensation program to strongly align with the Company's long-term strategy, competitive industry practice, sound corporate governance principles, and shareholder interests.

We urge our shareholders to read the Compensation Discussion and Analysis ("CD&A") section of this proxy statement for additional details on the Company's compensation philosophy and objectives and the fiscal year 2025 compensation of our named executive officers ("NEOs").

Pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), we are asking shareholders to approve the following resolution:

**RESOLVED, that the fiscal year 2025 compensation paid to the Company's named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion, is hereby APPROVED.** 

The Board and the Compensation Committee value the opinions of our shareholders and will consider the outcome of the vote when making future compensation decisions for our NEOs. However, as an advisory vote, the results of this proposal are non-binding, and neither the Board nor the Compensation Committee will have any obligation to take any action as a result of the Say-on-Pay vote.

**The Board recommends a vote "FOR" the non-binding resolution approving the fiscal year 2025 compensation paid to the NEOs, as disclosed pursuant to Item 402 of Regulation S-K, including in the Compensation Discussion and Analysis, compensation tables, and narrative discussion.**

| Corporate Governance & Board of Directors | ![](logo_magnerax2.jpg) |

---

#### Corporate Governance Principles
The Board and management are dedicated to effective corporate governance. The Board has adopted Corporate Governance Principles that provide a framework for the Company's governance. The Board has also adopted a Code of Business Conduct and a Code of Business Ethics for our CEO and Senior Financial Officers.

The Governance page of the Company's website at ir.magnera.com contains the Company's Amended and Restated Articles of Incorporation ("Articles of Incorporation"), Amended and Restated Bylaws ("Bylaws"), Corporate Governance Principles, Code of Business Conduct, a list of the directors of the Company, the charters of each standing committee of the Board, and the Code of Business Ethics for CEO and Senior Financial Officers.

Copies of these materials are also available, in print and at no charge, upon request to the Secretary of the Company at 9335 Harris Corners Parkway, Suite 300, Charlotte, NC 28269.

The Board reviews each of the Company's corporate governance documents annually and recommends revisions accordingly.

The Company intends to satisfy the disclosure requirement for any future amendments to, or waivers from, its Code of Business Conduct or Code of Business Ethics for CEO and Senior Financial Officers by posting such information on its website.

#### Board Composition and Leadership
The Board currently consists of nine members. Each year, the Board elects one of its non-executive members to serve as Board Chair. Under the Board's governance structure, the Board Chair:

&nbsp;&nbsp;&nbsp;&nbsp;• presides at all meetings of the Board, including executive sessions;

&nbsp;&nbsp;&nbsp;&nbsp;• identifies strategic issues to be considered for the Board agenda; and

&nbsp;&nbsp;&nbsp;&nbsp;• consults with directors on the development of the schedule, agenda, and materials for all Board meetings.

When considering the election of a Board Chair, the Board reviews its governance structure and the qualifications of each director and determines who is best qualified to chair the Board. The Board believes the Company and its shareholders are best served by having a Board Chair who has knowledge of the Company's business operations and industry and who can best oversee execution of the Company's strategic plan, based on his or her extensive experience and knowledge of the Company's operations, industry, competitive challenges, and opportunities.

Kevin M. Fogarty, an independent director, has served as the Board's Non-Executive Chair since August 24, 2022. Based on his prior CEO experience and his knowledge of the Company's business and industry, the Board determined that Mr. Fogarty is the director best qualified to serve in the role of Non-Executive Chair. The Board nominated Mr. Fogarty in November 2025 to continue as Non-Executive Chair, subject to and effective upon his re-election as a director at the Annual Meeting.

#### Committees of the Board of Directors
The Board has three standing committees: Audit, Compensation, and Nominating & Corporate Governance ("NCG"). Each standing committee has its own charter, which is available on the Company's website at ir.magnera.com. Paper copies of the charters are also available, at no charge, upon written request to the Company Secretary.

The Board determined that all members of each standing Committee are independent as required under the NYSE listing standards and the applicable SEC rules and regulations.

#### Board Independence
The Corporate Governance Principles and the Company's policies and procedures provide for an empowered Board, with a majority of independent members, and the full involvement of the independent directors in the Board's operations and decision-making. As set forth in the Company's Corporate Governance Principles, the Board has adopted the listing standards of the New York Stock Exchange (the "NYSE") for determining the independence of directors, which require that a director not have a material relationship with the Company.

Annually, each member of the Board is required to complete a questionnaire designed, in part, to provide information to assist the Board in determining if the director is independent under NYSE rules and our Corporate Governance Principles. In addition, each director or director nominee has an affirmative duty to disclose to the NCG Committee relationships between and among that director (or an immediate family member), the Company, or Company management.

The Board has determined the following directors are independent and have no material relationship with the Company: Messes. Hall and Marnick and Messrs. Brown, Curless, Fogarty, Rickertsen, and Salmon. The Board has determined Mr. Begle, as the Company's current CEO, and Mr. Fahnemann, as the former CEO of GLT, are not independent directors as defined under the NYSE listing standards and the Company's Corporate Governance Principles.

#### Evaluation of Board Nominees
The NCG Committee reviews all director nominations submitted to the Company, including individuals recommended by shareholders, directors, or members of management, using the same criteria. When evaluating whether to recommend an individual for nomination or re-nomination, the NCG Committee will consider, at a minimum and in accordance with the Company's Corporate Governance Principles, the candidate's independence, professional experience, diversity in personal background, knowledge of the Company's business or industry, skills, expertise, wisdom, integrity, business acumen and availability to devote the necessary time to serve on the Board.

The Board believes that diversity in personal background, professional experience, qualifications, attributes and skills, and how they complement, supplement, or duplicate those of other Board members can enhance the effectiveness of the Board and are important considerations in evaluating and selecting director candidates.

The NCG Committee reviews the qualifications of each incumbent director, including the director's understanding of the Company's business and the environment in which the Company operates, attendance, and participation at Board and applicable committee meetings, and independence, including any relationships with the Company. Prior to nomination, each candidate for director must consent to stand for election, and each director nominee must agree in writing to abide by the Company's Elections Policy set forth in its Corporate Governance Principles (as discussed in greater detail below).

After the NCG Committee has completed its evaluation of all director candidates, it presents a recommended slate of directors to the Board for consideration and approval. The NCG Committee also discusses with the Board any candidates considered by the NCG Committee but not recommended for election or re-election as a director.

The NCG Committee recommended, and the Board approved, the nomination of all nine incumbent directors for re-election at the Annual Meeting. These decisions were based on the individual experiences, qualifications, attributes, and skills of each candidate, including as described in the skills matrix in the "Board Skills and Experience" section of this proxy statement.

#### Resignation and Majority Voting Policy

#### Incumbent Director Irrevocable Resignation
Pursuant to the Elections Policy in our Corporate Governance Principles, each incumbent director standing for election to the Board must, as a condition to such nomination, tender an irrevocable resignation in advance of the Annual Meeting. If such director is not re-elected by a majority of the votes cast at the Annual Meeting, the NCG Committee will make a recommendation to the Board about whether to accept or reject the director's tendered contingent, irrevocable resignation. A director whose resignation is not accepted by the Board shall continue to serve until the next annual

Page \| 21<br>

------

#### **TABLE OF CONTENTS**
meeting of shareholders and until a successor has been elected and qualified, or until the earlier of their death, resignation, or removal. In making its recommendation, the NCG Committee will publicly disclose its decision and the rationale behind such decision within 90 days of certifying the final election results.

#### Majority Voting
Our Articles of Incorporation provide for a majority voting standard in uncontested elections of directors. The Board believes that a majority vote standard gives shareholders a greater voice in determining the composition of the Board by giving effect to shareholder votes "against" a director nominee and requiring a majority of votes cast to be "for" a director nominee in order for such nominee to obtain or retain a seat on the Board. Furthermore, a majority voting standard reinforces the Board's belief that it is accountable to, and should represent the interests of, all the Company's shareholders.

Similarly, our shareholders are afforded the protection of a "one share, one vote" framework in director elections. This prevents any individual shareholder from having the ability to exercise disproportionate voting power, control, or influence over director elections in excess of their actual economic ownership of our shares.

Pursuant to our Articles of Incorporation, our directors are elected as follows:

*Contested Election. Nominees receiving the highest number of votes, up to the number of directors to be elected in such election, shall be elected. Shareholders do not have the right to vote against a nominee.* 

*Uncontested Election. Nominees shall be elected if the votes cast for such nominee's election exceed the votes cast against such nominee's election. Abstentions and broker non-votes are not considered to be votes cast.* 

#### Proxy Access
Pursuant to the Bylaws, any eligible shareholder, or group of no more than 20 eligible shareholders, that complies with certain informational disclosure requirements set forth in Sections 1.9(d) and 1.10 of our Bylaws, is permitted to include a director nominee or nominees (not to exceed 20% of the number of directors) in the Company's proxy statement for its annual meeting.

In order to provide adequate time to assess shareholder-nominated candidates, requests to include shareholder-nominated candidates in the Company's proxy materials must be received by the Company Secretary at the principal executive offices of the Company not less than 120 days nor more than 150 days prior to the first anniversary of the preceding year's proxy statement mailing, subject to certain limited exceptions set forth in our Bylaws.

If no annual meeting was held in the preceding year, as was the case in 2025, a shareholder's notice must be received the later of 90 days prior to the annual meeting or 10 calendar days after the meeting date is publicly disclosed. Accordingly, to be considered a timely notice for inclusion in this proxy statement, a shareholder notice must have been received by December 9, 2025 per the Current Report on Form 8-K filed with the SEC on November 28, 2025.

#### Meeting Attendance
The Board held four meetings during fiscal year 2025. The Board's standing committees held a combined total of 11 meetings. Each director attended 88% or more of the total number of Board and standing committee meetings on which they served; overall attendance at such meetings was 99%. Non-executive directors meet in regularly scheduled Board executive sessions (without management), presided by the Non-Executive Chair.

All directors have been invited, and are strongly encouraged, to attend the Annual Meeting, but are not required to attend.

#### Continuing Board Education
We believe our shareholders are best served by a board that is well versed in subject matters relevant to board service and thoroughly comprehends the role and responsibilities of an effective board in the oversight and management of the Company. The Board regularly conducts Board education sessions on relevant topics for the Company's future growth and success and to stay informed about best governance practices. We also feel it is appropriate for our directors to have

Page \| 22<br>

------

#### **TABLE OF CONTENTS**
access to educational programs on an ongoing basis to assist them in performing their duties as directors. The Company will reimburse directors for the reasonable costs of attending relevant and timely director education programs approved by the Board's Non-Executive Chair. The Company is a member of the National Association of Corporate Directors. This membership provides continuing education programs, research data, conferences, and other resources for the Company's directors and executives. The NCG Committee periodically reviews and oversees orientation programs for newly elected directors and suggests topics for continuing education programs for incumbent directors.

#### Board Self-Assessment
Our Board believes in a constructive self-assessment process as a governance best practice to improve its performance and ensure it is functioning effectively. As required by our Corporate Governance Principles, the NCG Committee oversees an annual self-assessment of the Board and its standing committees. Each director completes a written questionnaire to gather suggestions for improvement and feedback on a range of issues related to Board and standing committee effectiveness. An outside consultant reviews the questionnaire responses and additionally conducts individual interviews with each director. The feedback is aggregated and summarized by the consultant, who shares the feedback with the Board. Changes to Board practices, procedures, policies, and agendas are considered and implemented in response to the feedback as appropriate.

#### Board Oversight
The Board plays an active role in risk oversight to ensure that management is taking appropriate actions to identify, evaluate, manage, and mitigate significant risks. The Board reviews risks associated with the Company's strategic plan and enterprise level risks annually. Periodically throughout the year, the Board actively monitors risks associated with the Company's strategic plan through formal business updates it receives from management, including an annual report from management on information technology security matters.

The Board administers its risk oversight responsibilities by delegating certain business and governance activities to the appropriate committees for more detailed consideration and evaluation. In performing this oversight function, each committee has full access to management, as well as the ability to engage advisors or other experts it deems necessary in the performance of its duties. At each regularly scheduled Board meeting, the Chair of each standing committee reports to the Board on the respective committee's oversight activities, as needed.

The Company's management is responsible for the day-to-day identification, evaluation, management, and mitigation of the Company's risk exposures. The Company manages these enterprise risks through a variety of policies, programs, committees, and internal controls designed to protect the Company's assets, operations, and reputation, while ensuring compliance with applicable laws and regulations.

#### Director Compensation
Non-employee directors receive compensation for their service that is designed to compensate them fairly for the time, effort, and accountability required of a director and to align their interests with our shareholders. In making non-employee director compensation recommendations to the Board, the Compensation Committee considered the analysis of director compensation of the Company's compensation peer group provided by Meridian Compensation Partners LLC ("Meridian"), the Compensation Committee's independent compensation consultant (see discussion regarding the compensation peer group in the CD&A.). Meridian's analysis included a review of annual cash retainers, annual equity grants, meeting fees, and committee fees compared to the compensation peer group.

#### Cash Compensation
In 2025, non-employee director compensation included the following cash fees for service:

&nbsp;&nbsp;&nbsp;&nbsp;• Annual Cash Retainer Fee: $100,000

&nbsp;&nbsp;&nbsp;&nbsp;• Additional Fees for those serving in role:

Audit Committee Chair: $25,000 <br>

Compensation Committee Chair: $20,000 <br>

NCG Committee Chair: $18,750 <br>

Non-Executive Chair: $130,000 <br>

#### Equity Compensation
Each non-employee director receives an annual RSU award with a target value of $150,000 based on the fair market

value of the shares on the grant date. Such RSU awards fully vest, all restrictions lapse, and the shares are paid out on the first anniversary of the grant date. RSUs granted to directors will immediately vest upon a separation from service without cause, including change in control, death, or disability.

In 2025, each independent director's annual award value of $150,000 was combined with a Transaction equity RSU award valued at $50,000 to recognize their involvement with pre-close activities associated with the Transaction. For these individuals, their 2025 annual award value increased to $200,000 in lieu of granting a separate award valued at $50,000. All non-employee directors are considered independent except for Mr. Fahnemann.

#### Other Benefits and Coverage
Each non-employee director is covered by the Company's director and officer liability insurance policy, has entered into an

indemnification agreement with the Company, and is covered under the Company's travel accident insurance policy.

#### Share Ownership Guidelines
The Company has established share ownership guidelines for non-employee directors to enhance their alignment with

shareholders' interests. The share ownership guidelines preclude the sale of shares by a director until he or she holds

shares with a value equal to five times the annual Board retainer of $100,000. Directly held shares and unvested RSUs

count toward attainment of the guideline. All non-employee directors are in compliance or on track to be in compliance

with the share ownership guidelines.

#### Say-on-Pay
Our executive compensation programs are designed to align the Company's short- and long-term performance with shareholder expectations. We are asking our shareholders to indicate their support for our NEOs' compensation as described in this proxy statement. While this vote is advisory, we value our shareholders' feedback and will review and take into consideration the results of our Say-on-Pay proposals when determining future executive compensation programs.

#### **TABLE OF CONTENTS**
The Board has adopted a policy providing annual Say-on-Pay advisory votes. Unless the Board modifies the Company's policy, the next Say-on-Pay advisory vote will be held at our 2027 Annual Meeting of Shareholders. The next advisory vote on the frequency of Say-on-Pay advisory votes ("Say-on-Frequency" vote) will be held at our 2028 Annual Meeting of Shareholders.

#### Executive Summary

#### 2025 Compensation Overview
On November 4, 2024, Treasure, which was a wholly owned subsidiary of Berry Global, completed the Transaction with GLT, which concurrently changed its name to Magnera. As a result of the Transaction, the following actions were taken by the Compensation Committee to establish the company's executive compensation program:

&nbsp;&nbsp;&nbsp;&nbsp;• Developed a compensation philosophy aligned to a reasonable range around the 50<sup>th</sup> percentile of the peer group compensation, comprised of base and incentive compensation, along with health, welfare, and retirement benefits.

&nbsp;&nbsp;&nbsp;&nbsp;• Evaluated an appropriately sized compensation peer group comprised of companies generally aligned to the industry, to use when hiring Magnera's NEOs.

&nbsp;&nbsp;&nbsp;&nbsp;• Approved the hiring of the NEOs, including a competitive compensation offering for each individual (details provided below).

&nbsp;&nbsp;&nbsp;&nbsp;• Designed Short-Term Incentive ("STI") and Long-Term Incentive ("LTI") programs to reward management for strong financial performance and to drive shareholder value in Magnera's first fiscal year.

&nbsp;&nbsp;&nbsp;&nbsp;○ Adjusted EBITDA ("Adj. EBITDA") and Post-Merger Adjusted Free Cash Flow were determined to be the two most important financial metrics for the STI and absolute stock price growth for the LTI.

&nbsp;&nbsp;&nbsp;&nbsp;• Developed additional executive compensation programs with input from the Committee's compensation consultant, including director and executive share ownership requirements, executive severance with market-driven, double-trigger change in control benefits, deferred compensation, and insider trading and clawback policies.

&nbsp;&nbsp;&nbsp;&nbsp;• Conducted a risk assessment of each compensation program to ensure sound design that did not encourage excess risk-taking by management.

&nbsp;&nbsp;&nbsp;&nbsp;• Reviewed and guided the development of Magnera's human capital strategy, organizational design, and cultural integration, which were essential to establishing the global organization.

#### **TABLE OF CONTENTS**
The Compensation Committee believes compensation should reflect the Company's financial performance and be competitive based on a person's responsibilities, individual performance, and ability to exemplify the Company's purpose, promise, and beliefs. The Compensation Committee recommends approval of the Company's compensation philosophy to the Board and oversees the compensation programs for the NEOs and other executive officers of the Company. All compensation decisions impacting the CEO are approved by the Compensation Committee and require the ratification and approval of the independent members of the Board.

Total compensation for the NEOs and other Company executive officers consists of base salary, short- and long-term incentives, retirement and other benefits, and minimal perquisites. The Company's executive compensation programs generally target total compensation at a reasonable range around the 50<sup>th</sup> percentile of its compensation peer group for a given year (see "Compensation Peer Group and Benchmarking Process" for a discussion of the compensation peer group). A significant portion of each NEO's compensation is tied to the Company's financial performance. The opportunity to earn incentive compensation, and the level of pay at risk, increases commensurate with the NEO's level of responsibility, with the CEO having the greatest amount of pay at risk.

The Compensation Committee reviews the incentive plans annually, as discussed in the "Risk Management" section of this proxy statement, to determine whether they present undue risk to the Company. Based on this review of the incentive plans and input from the independent compensation consultant (the "Consultant"), the Compensation Committee determined the Company's compensation policies and practices are not reasonably likely to have a material adverse impact on the Company.

#### 2025 CEO Compensation Highlights
Mr. Begle's experience leading the legacy Health, Hygiene, and Specialties division at Berry Global and deep industry knowledge and experience were key factors in appointing him as CEO for Magnera and for establishing his 2025 compensation as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• An annual award with a 2025 target value of $4,600,000, comprised of 75% performance-based restricted stock units and 25% time-based restricted stock units.

&nbsp;&nbsp;&nbsp;&nbsp;○ Performance shares are tied to the achievement of stock price growth hurdles established by the Board, at the conclusion of a three-year performance period

&nbsp;&nbsp;&nbsp;&nbsp;○ Time-based restricted stock units to be earned ratably over a three-year period, subject to continuous employment

&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Begle received a special Transaction-related cash retention bonus of $750,000 paid in May 2025, six months following the closing of the Transaction. This payment represents Magnera's obligation under the terms established by Berry Global prior to Transaction close.

&nbsp;&nbsp;&nbsp;&nbsp;• To further aid in the retention of Mr. Begle during the critical first three years of Magnera's existence, the Board approved a special, one-time, time-based restricted stock unit grant valued at $1,500,000 to cliff vest at the end of a three-year period, subject to continuous employment.

&nbsp;&nbsp;&nbsp;&nbsp;• In addition to his TDC, Mr. Begle is eligible to participate in the Company's NQDC plan and is subject to the Clawback and Insider Trading policies. He is also eligible for health, welfare, and retirement programs with the same benefit levels available to salaried employees and he has limited perquisites, which include ability to opt into an annual executive health physical and executive long-term disability.

#### 2025 NEO Compensation Overview and Highlights

In addition, effective November 4, 2024, the Board approved a special, one-time, time-based equity grant in the form of RSUs to aid in the retention of the executive leadership team during the critical first three years of Magnera's existence. The terms and conditions are the same as Mr. Begle's special equity grant, including cliff vesting at the end of a three-year period, subject to continuous employment, except in the case of Mr. Parks and Ms. Beck who will be credited with continuous vesting after having remained employed for the first year of the award's vesting cycle, as defined by the grant's retirement provisions. Below are the equity grant award values for each individual.

| Till | $500000  |
| Manroa | $500000  |
| Parks | $250000  |
| Beck | $250000 |

---

Under terms established by Berry Global for Mr. Parks and GLT for Ms. Beck prior to the Transaction, a special Transaction-related retention cash bonus of $205,000 and $185,000, respectively, was paid by Magnera six months following the closing of the Transaction. Messrs. Till and Manroa did not participate in the special Transaction-related retention bonus program given their broad, global roles while employed by Berry Global prior to the Transaction.

#### Compensation Programs

#### Determination of Compensation Levels
The Compensation Committee seeks input from certain NEOs, external advisors, and other Company executives when determining compensation decisions. Specifically:

---

| |
|:---|
| The Compensation Committee retains a consultant that regularly meets with the Compensation Committee in executive session to provide advice, information, and analysis on executive compensation and benefits.  |
| The Compensation Committee confers with the Consultant, the CEO, and the CHRO to design compensation programs and obtain background on the Company's key financial objectives, metrics, and performance, and design of the Company's short- and long-term incentive compensation programs. Also, the CFO participates in establishing the financial objectives and metrics, and determining the plan's final performance compared to the pre-established financial metrics.  |
| Compensation decisions pertaining to the CEO are ratified by the independent members of the Board, based on recommendations by the Compensation Committee and guidance from the Consultant.  |
| Compensation decisions pertaining to the NEOs, other than the CEO, are made by the Compensation Committee with consideration of recommendations from the CEO and guidance from the Consultant.  |
| The Company's legal counsel and Human Resources staff provide legal, governance, and technical input to the Compensation Committee with oversight by the Consultant. |

---

Page \| 33<br>

------

#### **TABLE OF CONTENTS**
The Compensation Committee may invite NEOs or other executive officers to attend portions of its meetings; however, the Compensation Committee meets in executive session alone, with and without the Consultant, to reach final decisions regarding NEO compensation. Additionally, while the CEO makes recommendations to the Compensation Committee on the other NEOs' compensation, he does not provide input or partake in the discussions and deliberations regarding his own compensation.

To assist with reviewing NEO compensation, the Compensation Committee considers market benchmark data, pay history, tally sheets, vested and unvested equity holdings, and required share ownership. The Compensation Committee uses this information, in addition to market compensation data, individual NEO and Company performance, and the Company's succession planning when making compensation decisions for each NEO.

The Compensation Committee retains the consulting services of Meridian to:

&nbsp;&nbsp;&nbsp;&nbsp;• provide competitive compensation market data

&nbsp;&nbsp;&nbsp;&nbsp;• assess the competitiveness of the executive compensation programs

&nbsp;&nbsp;&nbsp;&nbsp;• make recommendations regarding program design based on prevailing market practices and business conditions

&nbsp;&nbsp;&nbsp;&nbsp;• advise the Compensation Committee on:

&nbsp;&nbsp;&nbsp;&nbsp;○ the level of each NEO's compensation

&nbsp;&nbsp;&nbsp;&nbsp;○ the composition of the compensation peer group

&nbsp;&nbsp;&nbsp;&nbsp;○ incentive plan performance metrics and design

&nbsp;&nbsp;&nbsp;&nbsp;○ external trends and regulatory developments

&nbsp;&nbsp;&nbsp;&nbsp;○ changes or enhancements to the Company's executive compensation policies

&nbsp;&nbsp;&nbsp;&nbsp;○ Say-on-Pay guidance and input

&nbsp;&nbsp;&nbsp;&nbsp;○ any potential risk to the Company as a result of the compensation programs' design and overall structures

#### Compensation Peer Group and Benchmarking Process
To determine market levels, the Company targets a reasonable range around the 50<sup>th</sup> percentile of the Company's peer group companies (the "Compensation Peer Group"), and the Compensation Committee reviews target total compensation for similarly situated executives from the Compensation Peer Group where data is available, as well as from multiple nationally-recognized compensation survey sources including:

&nbsp;&nbsp;&nbsp;&nbsp;• William H. Mercer's Executive Compensation Database

&nbsp;&nbsp;&nbsp;&nbsp;• Willis Towers Watson's Executive Compensation Database

For 2025 compensation decisions, the market review included the total compensation of the CEO, CFO, COO and all other NEOs.

The Compensation Peer Group is comprised of size-appropriate peer companies that share common industry and financial characteristics and compete with the Company for executive and employee talent. The Compensation Committee annually reviews the Company's peer group companies to ensure they are a relevant and appropriate peer group.

Below is the list of companies the Compensation Committee used to establish 2025 compensation decisions:

---

| | |
|:---|:---|
| **2025 Compensation Peer Group**  | **2025 Compensation Peer Group**  |
| AptarGroup, Inc.  | Packaging Corporation of America  |

#### Target Pay Mix
Annually, the Compensation Committee reviews each NEO's compensation mix of base salary, STI, and LTI, which comprises total target direct compensation for each NEO, to ensure that an appropriate level of the NEO's recurring target compensation is tied to Company performance. The Compensation Committee believes this approach is appropriate to provide year-over-year consistency in analyzing the pay mix when compared to the Compensation Peer Group.

The targeted annual pay mix of compensation varies for each NEO, with an average of 68% of target pay considered at- risk for the NEOs (excluding the CEO). This average does not include one-time equity grants or other health, welfare, or retirement benefits. Consistent with the Company's compensation philosophy, Mr. Begle has the highest level of STI and LTI target opportunity compared to the other NEOs, with 85% of his annualized total target direct compensation considered at-risk and variable. The Compensation Committee believes this level is appropriate for Mr. Begle given his responsibility as CEO to deliver on the Company's long-term strategy and Transaction objectives, and to ensure alignment with shareholder expectations.

The charts below illustrate the mix of CEO and aggregate other NEOs' 2025 compensation by type and form at target (excluding the one-time equity grants and other health, welfare, or retirement benefits):

![](ny20057004x1_piechart1.jpg)

#### Base Salary
The Compensation Committee believes base salary, which contributes to the Company's compensation objectives of attracting and retaining talented executives, is an important element of compensation. The base salaries of the NEOs are reviewed and approved annually by the Compensation Committee and, in the case of the CEO, ratified by the independent members of the Board. The Compensation Committee considers several factors, without any assigned relative weightings, when determining base salary increases for NEOs:

&nbsp;&nbsp;&nbsp;&nbsp;• Salary recommendations from the CEO for the NEOs other than himself

&nbsp;&nbsp;&nbsp;&nbsp;• Company and individual NEO performance

&nbsp;&nbsp;&nbsp;&nbsp;• Accountability and complexity of the NEO's role in attaining Company objectives

&nbsp;&nbsp;&nbsp;&nbsp;• External competitiveness of the NEO's compensation

&nbsp;&nbsp;&nbsp;&nbsp;• Internal equity and retention considerations

&nbsp;&nbsp;&nbsp;&nbsp;• Executive succession planning

&nbsp;&nbsp;&nbsp;&nbsp;(2) Base salaries were set at the time of the Transaction, and no further adjustments were made during the fiscal year.

#### Short-Term Incentives ("STI")
The Company provides an annual bonus opportunity to the NEOs under the Company's STI program. The Compensation Committee approves a target bonus for each NEO expressed as a percentage of the NEO's base salary. Generally, the Compensation Committee establishes target bonuses for the NEOs in a reasonable range around the 50<sup>th</sup> percentile of the Company's compensation peer group for a given year.

![](ny20057004x1_metric.jpg)

In November of each year, the Compensation Committee, in consultation with the Audit Committee Chair, determines the degree to which the pre-established STI performance metrics have been met with respect to the prior fiscal year. The Compensation Committee then decides whether — and if so, at what percentage level — to award bonuses to the NEOs.

The amount ultimately earned by the NEOs depends on the achievement of performance metrics; provided, however, the Compensation Committee may, in its discretion, adjust any bonus of a NEO downward based on its judgment of management's achievement of the financial outcomes. Any downward adjustment to the CEO's bonus requires ratification and approval by the independent members of the Board. The Board made no downward adjustments to Mr. Begle's STI payment, nor did the Compensation Committee make any downward adjustments to the STI payments for the remaining NEOs.

The 2025 STI was based on Adj. EBITDA achievement weighted 75% and Post-Merger Adjusted Free Cash Flow weighted 25%. The Adj. EBITDA metric had a threshold of 90% achievement of target performance (which pays 50% of the target award) and a ceiling of 109% achievement (which pays 200% of the target award). Adj. EBITDA performance below threshold levels results in a zero payout for that metric. The Post-Merger Adjusted Free Cash Flow metric also had a threshold of 90% achievement of target performance (which pays 50% of target award) and a ceiling of 110% achievement (which pays 200% of target award). Post-Merger Adjusted Free Cash Flow performance below threshold results in a zero payout for that metric.

&nbsp;&nbsp;&nbsp;&nbsp;• Adj. EBITDA (weighted 75%) – a non-GAAP measure, is defined as the Company's earnings minus its costs, after excluding from such costs interest expense, taxes, depreciation, and amortization subject to adjustment (such as foreign exchange adjustments and timberland sales) as determined by the Compensation Committee. Adj. EBITDA target is annualized and spans from October 2024 through September 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• Post-Merger Adjusted Free Cash Flow (weighted 25%) – is defined as the Company's cash flow with adjustments to appropriately address the treatment of deal-related cash flows at the time the Transaction was completed, and spans from the Transaction closing date through September 2025.

These metrics are intended to focus the NEOs on generating strong earnings and cash flow, which were important to achieving Magnera's first year of financial performance.

The 2025 targeted performance levels for both metrics were derived from the Company's 2025 annual operating plan as approved by the Board. Developing Magnera's first year operating plan and the critical business priorities required to achieve targeted performance levels involved a variety of factors and assumptions, including but not limited to the projected revenues, earnings, synergies, and capital investments as a result of combining the two originating companies.

All financial performance targets were established at the start of the fiscal year. No adjustments were made to change or lower the performance targets, on account of the impacts from any internal/external business conditions.

Payouts are determined by the Compensation Committee based on actual financial achievement compared to the targets established at the beginning of the year (see "Annex A" for a discussion of the reconciliations of GAAP to Non-GAAP numbers).

The following table outlines the approved threshold, target, and maximum payment opportunities and financial goals for the NEOs under the 2025 STI, as well as the weighted payout results based on the performance metric weightings.

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Eligible salaries reflect a prorated annual amount of 11 applicable months, due to the beginning of the fiscal year starting upon the close of the Transaction.

#### Long-Term Incentives ("LTI")
The Compensation Committee believes long-term compensation provides strong incentive for executives to deliver and sustain long-term financial performance to benefit the Company's shareholders. Annually, the Compensation Committee determines the target opportunity of LTI compensation to be granted to executives by targeting a reasonable range around the 50<sup>th</sup> percentile of the peer group but reserves discretion to deviate from the target.

The Company provided NEOs an annual LTI equity award comprised of 75% PSUs and 25% time-based RSUs.

2025 PSUs:

&nbsp;&nbsp;&nbsp;&nbsp;• The LTI program is designed to be primarily performance-based, with 75% of each NEO's grant date equity value (at target) awarded in PSUs that are tied directly to the Company's achievement of stock price growth hurdles over a three-year performance period. The stock price growth hurdles were derived from multi-year historical stock price growth trends of peers and the Company's anticipated stock price growth given certain assumptions regarding financial performance for the performance period.

&nbsp;&nbsp;&nbsp;&nbsp;• PSUs were granted after the completion of the Transaction to allow for a stock settling period following closing. The number of shares was determined using a 15-day volume-weighted average stock price of $18.89 for the period of November 11, 2024 through November 29, 2024. A Monte Carlo value of $25.32 was used to determine the accounting value of awards.

&nbsp;&nbsp;&nbsp;&nbsp;• The PSUs granted to the NEOs will be settled in shares of Company common stock and are payable at the end of three years based on achievement of the performance stock price goals and continuous employment.

Page \| 38<br>

------

#### **TABLE OF CONTENTS**
2025 RSUs:

&nbsp;&nbsp;&nbsp;&nbsp;• The time-based RSUs granted to the NEOs are weighted 25% of the annual LTI award value and will vest equally in one-third increments on the first, second, and third anniversaries of the grant date.

2025 One-Time Special Award:

&nbsp;&nbsp;&nbsp;&nbsp;• To further aid in the retention of each NEO during the critical first three years of Magnera's existence, the Board approved a special, one-time, time-based restricted stock unit award that cliff vests at the end of a three-year period, subject to continuous employment.

#### Vesting of Previous Grants
Under the terms of the Transaction, Ms. Beck's outstanding PSUs awarded by GLT were accelerated upon the closing of the Transaction. Her GLT RSUs were converted into Magnera RSUs and remained outstanding. In addition, all vested stock-only stock appreciation rights ("SOSARs") were converted into Magnera SOSARs. The converted RSUs and SOSARs continue to be subject to the same terms and conditions, including vesting and expiration schedules, as originally granted. All awards, including the strike prices of the converted SOSARs, were adjusted to reflect a 1-for-13 reverse stock split effective on November 4, 2024. Details of Ms. Beck's GLT RSUs that vested during fiscal year 2025 are presented in the "Grants of Plan-Based Awards" section.

#### Perquisites
Consistent with market practice, the Company provides limited perquisites. The Compensation Committee believes perquisites should be a minimal part of executive compensation and focused on the executive's well-being. All NEOs are eligible to receive a Company-paid executive physical and opt into executive long-term disability coverage. More information on the perquisite costs can be found in the Summary Compensation Table.

#### Retirement Compensation
The Compensation Committee believes offering market-aligned retirement benefits allows the Company to attract, retain, and motivate qualified employees and executives in the current competitive marketplace.

Page \| 39<br>

------

#### **TABLE OF CONTENTS**
During 2025, the Company provided a qualified 401(k) plan for U.S.-based employees. Messrs. Begle, Till, Manroa and Parks each received a company matching benefit based on their individual contributions to their plan, which mirrored the terms of their legacy plan while working for Berry Global. Ms. Beck received a company contribution of 3% of her base earnings consistent with the terms of the legacy Glatfelter plan. The 401(k) contributions of all NEOs were subject to the 2025 Internal Revenue Code ("Code") tax rules and regulations. Beginning in 2026, Magnera is implementing a single, integrated 401(k) plan in which the NEOs will receive up to a 4% company match provided they contribute 8% of eligible earnings and remain actively employed throughout the year.

Effective November 4, 2024, the Company began offering a non-qualified deferred compensation plan ("NQDC plan") which coordinates with the 401(k) plan by providing a Company match related to compensation in excess of the 401(k) plan limits, with a maximum non-qualified contribution of 3% of such excess compensation, provided the executive contributes 6% to the plan. Executive officers can elect to defer compensation under the NQDC plan up to a maximum of 90% of base salary and STI, above the IRS limit. All NEOs were participants in the NQDC plan in 2025. Because the employer match is funded after the fiscal year ends, applicable earnings for fiscal year 2025 will be reflected in future disclosures.

Ms. Beck is also a participant in a legacy GLT NQDC plan that was originally established to replace the Supplemental Executive Retirement Plan ("SERP"), which was frozen effective December 31, 2019. The legacy GLT NQDC plan coordinated with the 401(K) plan by providing a company contribution related to compensation in excess of the IRS limit. The frozen legacy GLT SERP accumulates interest at the end of each calendar year. Additional details of NEO retirement programs can be found in the Non-Qualified Deferred Compensation Table below. Information regarding Ms. Beck's frozen SERP balance is reflected in the Pension Benefits Table below.

#### Additional Compensation Policies and Practices

#### Executive Severance Plan and Double-Trigger Equity Vesting
The Company has an Executive Severance Plan to serve as the basis for determining the severance benefits available to the executives in the case of certain terminations of employment from the Company (other than for cause, resignation, death, or disability, each as defined in the Executive Severance Plan). The Compensation Committee retains the authority to modify or terminate severance arrangements, in its discretion, as circumstances may warrant. Additional details on severance and potential payments in the event of a termination of employment are discussed in the "Potential Payments upon Termination or Change in Control" section.

Under the Company's Executive Severance plan, eligible NEOs receive change in control ("CIC") benefits. The Compensation Committee believes these arrangements serve as an incentive for the NEOs to act in the interest of shareholders in the event of a CIC, without regard to personal risks related to their continued employment resulting from a CIC. The CIC terms provide for severance and other benefits to be paid to the NEOs upon a qualifying CIC. Magnera CIC benefits do not include any tax gross-up provisions for excise taxes imposed under the Code.

The Company's equity grant agreements include "double-trigger" provisions that accelerate vesting in the event of a CIC if the executive is terminated without "cause" or resigns with "good reason" (each as defined in the Executive Severance Plan). The Compensation Committee believes that the double-trigger provision ensures continuity of management during mergers and acquisitions and assists with retaining key executives, ultimately benefiting shareholders. Additional details on the CIC provisions and potential payments in the event of a CIC are discussed in the "Potential Payments upon Termination or Change in Control" section.

#### Share Ownership Guidelines
The Compensation Committee believes it is important to require the Company's non-employee directors and senior executives to meet minimum share ownership guidelines.

Page \| 40<br>

------

#### **TABLE OF CONTENTS**
The share ownership guidelines require the CEO, CEO direct reports, Section 16 officers and non-employee directors (collectively, "Participants") to accumulate and hold a meaningful level of Magnera stock to align the interests of management and the shareholders and ensure good governance practices. The Compensation Committee determines the guidelines using a multiple of each Participant's base salary:

---

| |
|:---|
| **Position** |
| CEO<br> 6x  |
| CEO Direct Reports and Section 16 Officers<br> 3x  |
| Non-Employee Directors<br> 5x |

---

The value of required ownership is reviewed and adjusted annually for salary increases and the number of shares needed to be owned will be affected by changes in stock price. Directly owned shares and beneficially owned shares held indirectly (e.g., by family members, trusts, etc.) are eligible for satisfying ownership guidelines.

Unvested RSUs and earned but unvested PSUs also count towards satisfying the ownership guidelines. As of the 2025 review, participants were compliant with the guidelines by either achieving the ownership multiple or adhering to a holding requirement as outlined below.

#### Holding Requirement
Until the executive share ownership level is attained, Participants must retain 50% of net profit shares realized at (i) payment of performance shares; (ii) vesting of restricted shares; and (iii) exercise of SOSARs. The Compensation Committee reviews progress toward satisfying the requirements annually.

#### Clawback Policy
The Board adopted a Clawback Policy comprised of the mandated Dodd-Frank Clawback requirements that is applicable to the current and former Section 16 Officers. The Board also adopted an additional supplemental, discretionary Clawback Policy that works in conjunction with the Dodd-Frank Clawback policy and extends to the Company's broader management team. Below is an overview of the two policies:

---

| | | |
|:---|:---|:---|
| &nbsp;&nbsp;**Provision** | **Magnera Dodd-Frank Clawback** <br>**Compensation Recoupment Policy** | **Magnera Discretionary Clawback** <br>**Compensation Recoupment Policy**  |
| &nbsp;&nbsp;**Covered** <br>**Population** | • Current/former Section 16 Officers<br>| • Section 16 Officers<br>• Key Managers – any participant who received incentive compensation under STI or LTI plans during a period where a restatement or misconduct occurred<br>• Executive Officer/Key Manager in an upward direct reporting hierarchy to the covered individuals <br>|
| &nbsp;&nbsp;**Recoupment Trigger** | • Any accounting restatement resulting from material noncompliance (no fault requirement)<br>| • Accounting restatement resulting from material noncompliance, where lower payment would have otherwise been made<br>• Intentional misconduct <br>|
| &nbsp;&nbsp;**Subject** <br>**Period** | • Three completed fiscal years prior to restatement<br>| • Paid within three-year period prior to restatement resulting in excess incentive payment<br>• Paid during any fiscal year in which intentional misconduct occurred <br>|
| &nbsp;&nbsp;**Covered** <br>**Incentive-Based** <br>**Compensation** | • Incentive compensation granted, earned, or vested based on attainment of a "Financial Reporting Measure"<br>| • Bonuses or awards (including stock options and SOSARs) under the Company's short- and long-term incentive plans <br>|
| &nbsp;&nbsp;**Recoupment** | • Mandatory, except if recovery is "impracticable" (i.e., direct cost of recovery exceeds amount of recovery, prohibited by law, or would violate qualified retirement plan rules)<br>| • Discretionary as determined by the Board of Directors <br>|
| &nbsp;&nbsp;**Recoupment** <br>**Method** | • Methods include offset from future earnings or grants, recovery of previously paid compensation/gains, cancellation/forfeiture of existing awards, etc.<br>| • Board may seek direct repayment of any amounts to be recovered under the policy unless it is determined as unreasonable or adversely impacts the interest of the Company (i.e., likelihood of success to recover claimed excess under governing law, cost and effort of recovery, claims and/or investigations)<br>|

#### **TABLE OF CONTENTS**

#### Hedging and Pledging Policies
Directors and all employees, including the NEOs, are subject to an insider trading policy that prohibits such individuals from engaging in transactions in financial instruments (including, for example, prepaid variable forward contracts, equity swaps, collars, or exchange funds, as well as any other hedging instrument) designed to hedge or offset any decrease in the market value of Company stock. Our insider trading policy also prohibits covered persons from holding Company stock in a margin account or pledging our stock as collateral for a loan.

#### Tax Deductibility under Internal Revenue Code Section 162(m)
Section 162(m) of the Code generally imposes a $1 million deduction limitation on compensation paid to certain executive officers of a publicly held corporation during the year. The executive officers to whom the Section 162(m) deduction limit applies include the Company's CEO and CFO, the next three most highly compensated executive officers, and any such "covered employee" for any year after 2016. The Compensation Committee reserves discretion to award compensation that is not deductible under Section 162(m), as the Compensation Committee deems appropriate.

#### Role of the Compensation Committee and Consultant Independence
The Compensation Committee is responsible for approving NEO compensation, and, in the case of the CEO, submits the CEO's pay for ratification and approval by the independent members of the Board. The Chair of the Compensation Committee is responsible for leading the Compensation Committee. The Compensation Committee may form subcommittees and delegate authority to them as it deems appropriate; provided that any subcommittee must be solely comprised of one or more members of the Compensation Committee and such delegation should not otherwise be inconsistent with law and applicable rules and regulations of the SEC and the NYSE. Additionally, the Compensation Committee may delegate to the Company's management any or all of its authority under any incentive plan to make grants to non-executive officer employees, to the extent the Compensation Committee deems appropriate, consistent with the terms of the applicable incentive plan and applicable law.

The Compensation Committee has the authority to engage compensation consultants, legal counsel, or other advisors, as needed. The Compensation Committee provides oversight and approves related fees and retention terms of the consultants, counsel, or advisors, and may select a compensation consultant, legal counsel, or other advisor after assessing that person's independence from management and members of the Compensation Committee.

The meetings of the Compensation Committee are regularly attended by the Consultant. The CEO, CHRO, and General Counsel and Corporate Secretary also generally attend the Compensation Committee meetings. All members of management present at a meeting of the Compensation Committee, including the CEO, are excused from the meeting prior to any discussion of their compensation. The Compensation Committee holds a final executive session with only Compensation Committee members present before approving any compensation.

During 2025, the Compensation Committee retained Meridian Compensation Partners, LLC ("Meridian") as its Consultant to provide advice and assistance to the Compensation Committee and to management with respect to executive officer and non-employee directors' compensation. The Consultant reports directly to the Compensation Committee and has been authorized by the Compensation Committee to work with certain executive officers of the Company and other employees in the Company's human resources, legal, and finance functions.

The Compensation Committee has established several practices to ensure the Consultant's independence, candor, and objectivity. The Consultant is engaged by and reports directly to the Compensation Committee, frequently meets separately with the Compensation Committee with no members of management present, and consults with the Compensation Committee's Chair between meetings, as needed. Management periodically reports to the Compensation Committee the fees paid for services performed by the Consultant, and the Compensation Committee approves the annual work plan and budget for the Consultant. In 2025, the Compensation Committee assessed the independence of Meridian and other outside advisors as required under the NYSE listing standards, and considered and assessed all relevant factors, including those required by the SEC that could give rise to potential conflict of interests with respect to Meridian. Based on this review, the Compensation Committee did not identify any conflict of interest raised by the work conducted by Meridian for 2025. Meridian does not perform any work for the Company other than as the Consultant and accordingly, no fees were paid for any additional services.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Amounts reflected include salary paid during the fiscal year starting November 4, 2024, and ending September 27, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Represents the Transaction-related retention cash bonuses Magnera paid Messrs. Begle and Parks and Ms. Beck six months following the closing of the Transaction, in accordance with terms established by Berry Global and GLT, respectively, prior to the Transaction. Messrs. Till and Manroa were not eligible for this program given their broad, global roles while employed by Berry Global prior to the Transaction.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The amounts reflect the grant date fair value of RSUs (annual and one-time special) and/or PSUs granted in 2025 determined in accordance with ASC Topic 718. The grant date fair values of the 2025 PSUs are reported based on the probable outcome of being earned at the target level. If the 2025 PSUs are earned at the maximum level (200% of target), the grant date fair value of the 2025 PSUs would be as follows: Mr. Begle $9,248,687; Mr. Till $2,412,692; Mr. Manroa $1,809,519; Mr. Parks $1,005,255 and Ms. Beck $1,005,255, based on a Monte Carlo value of $25.32 which was derived by the grant date stock price.

&nbsp;&nbsp;&nbsp;&nbsp;(4) The amounts reflect cash payments under the Company's STI. See discussion of the STI in the CD&A.

&nbsp;&nbsp;&nbsp;&nbsp;(5) The amount reflected applies to Ms. Beck's legacy GLT SERP benefit, which was frozen in 2019. The frozen SERP benefit for Ms. Beck was converted to an opening balance in the NQDC plan as of January 1, 2020, and accrues interest annually under the GLT NQDC plan using the Moody's Aa bond yield for the month of November of the preceding year. Interest was calculated for the 2024 plan year on the frozen SERP balances at the annual rate of 5.33%. The frozen SERP balance is accounted for as a defined benefit plan in the Company's financial statements and, accordingly, the Company has treated such amounts consistent with disclosure for a defined benefit plan in the Summary Compensation Table. The estimated amounts reflect the actuarial increase in the present value of the frozen SERP balance under the NQDC plan, based on interest rate and mortality assumptions that are consistent with those used in the Company's financial statements and further defined in the Pension Benefits Table in the "2025 Retirement Benefits" section. If the frozen SERP balances had been considered a defined contribution plan, then "All Other Compensation" in the Summary Compensation Table would have included $1,000 of above-market interest for Ms. Beck who has a frozen SERP balance, instead of the amount shown in the "Change in Pension Value and NQDC Earnings" column. For information regarding the frozen SERP balances, please refer to footnote (1) to the Pension Benefits Table in the "2025 Retirement Benefits" section.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Includes amounts received under the NEO's respective 401(k) Plan. Messrs. Begle, Till, Manroa, and Parks participate in the Treasure HoldCo 401(k) plan which earned a company match of 50% of up to 6%, funded each January. Amounts reflected for Treasure HoldCo 401(k) participants are associated with match earned in the prior plan year. Ms. Beck participates in the Magnera 401(k) plan which earns a 3% company contribution on earnings in excess of the annual Code limit, paid in each pay cycle of fiscal year 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Amount reflected for Ms. Beck comprised of contributions made under the legacy GLT NQDC plan for the months of November and December 2024. The Magnera NQDC plan match will be funded in January after the plan year ends, therefore no employer contributions under this plan are reflected for fiscal year 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Reflects amounts paid for NEOs who opted into Executive Disability benefits.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Represents target, threshold, and maximum STI values awarded under the Company's STI program in 2025. Target amount is based on a prorated annual salary of 11 applicable months, due to the beginning of the fiscal year starting upon the close of the Transaction. Threshold payments equal 50% of the target amount, and maximum payments equal 200% of the target amount. For 2025, achievement of the performance goals resulted in STI payments as described in the NEO STI Payments table of the CD&A.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The target amounts reflect the number of PSUs granted to the NEOs in 2025 under the LTI program. A 15-day volume-weighted average stock price of $18.89 for the period ranging from November 11, 2024 through November 29, 2024 was used to determine the number of shares granted. The actual number of shares paid out will range from 0% to 200% of the target amount, depending upon attainment of stock price hurdle goals after a three-year period.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The amounts shown reflect the RSUs granted to the NEOs in 2025 under the LTI program. The annual RSU award vests equally in one-third increments on the first, second, and third anniversaries of the grant date. The one-time special RSU award has a three-year cliff vesting requirement.

&nbsp;&nbsp;&nbsp;&nbsp;(4) PSU values reflect a Monte Carlo valuation of $25.32 applied to the target payout amount. RSU values are based on the fair market value of $21.05 on the grant date.

#### Magnera Non-Qualified Deferred Compensation Plan
Effective November 4, 2024, the Company began offering a non-qualified deferred compensation plan ("NQDC plan") which coordinates with the 401(k) plan by providing a Company match related to compensation in excess of the 401(k) plan limits, with a maximum non-qualified contribution of 3% of such excess compensation, provided the executive contributes 6% of base earnings in excess of the annual Code limit to the plan. Executive officers can elect to defer compensation under the NQDC plan up to a maximum of 90% of base salary and STI, above the IRS limit. All NEOs were participants in the NQDC plan in 2025. Because the employer match is funded after the fiscal year ends, applicable earnings for fiscal year 2025 will be reflected in future disclosures. Accounts in the NQDC plan attributable to Company contributions are credited with earnings based on the investment return of funds in which such participant accounts are invested on a notional basis; participant deferrals are funded in a rabbi trust.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Amounts reflect elective deferrals into the Magnera NQDC plan in fiscal year 2025 for Messrs. Begle, Till, Manroa, and Parks and Ms. Beck. Deferral elections on 2025 base salary and 2025 bonus earned above the IRS limit were as follows: Mr. Begle 75%, and Messrs. Till, Manroa, and Ms. Beck 6%. Mr. Parks elected to defer 6% of his base salary but did not elect to defer any of his 2025 bonus.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Registrant contributions are paid in the form of a match following the end of the plan year. Given the timing of the fiscal year, no registrant contributions are noted for participants in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Represents aggregate gains and losses on all accounts attributable to Company contributions and participant deferrals to the NQDC plan, based on the investment return of funds in which such participant accounts were invested on a notional basis.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Amounts listed reflect the cumulative aggregate balance in all accounts under the NQDC plan as of September 27, 2025.

#### Additional Legacy GLT Pension Benefits and Non-Qualified Deferred Compensation Plan for Ms. Beck
Ms. Beck is also a participant in a legacy GLT NQDC plan that was originally established to replace the Supplemental Executive Retirement Plan ("SERP"), which was frozen effective December 31, 2019 and subsumed under the legacy GLT NQDC plan. No additional benefits have accrued under the SERP after December 31, 2019, and no new participants are eligible to participate. The legacy GLT NQDC plan coordinated with the 401(K) plan by providing a company contribution related to compensation in excess of the IRS limit. The SERP accumulates interest at the end of each calendar year.

As of January 1, 2020, the present value of the frozen SERP benefits for Ms. Beck was credited to the legacy GLT NQDC plan established by the Company and accrues interest annually using the Moody's Aa bond yield for the month the interest rate is set (which is November of the year preceding the year for which interest is credited). The frozen SERP balance, with interest, will be paid in the same form and at the same time as previously provided for under the SERP. Although the frozen SERP balances have been subsumed within the legacy GLT NQDC plan, the Company has accounted for them as a separate defined benefit plan in its financial statements. Accordingly, the Company has disclosed Ms. Beck's frozen SERP balance information in the Pension Benefits Table below. All legacy GLT SERP and NQDC plan benefits remain unfunded.

|:---|:---|
| &nbsp;&nbsp;**Terms of Ms. Beck's Frozen SERP**  | &nbsp;&nbsp;**Terms of Ms. Beck's Frozen SERP**  |
| &nbsp;&nbsp;Restoration Benefit | The SERP provides participants whose benefits under the retirement plan were reduced due to legal limits with a supplemental pension benefit. The supplemental benefit restored the portion of the pension benefit that was earned but not able to be paid under the retirement plan because of the legal limits provided in the Code. The SERP calculation considered, as a reduction to the benefit, the participant's retirement plan benefits and certain 401(k) contributions and is paid in the form of an annuity. Ms. Beck is the only 2025 NEO with this benefit. |

#### **TABLE OF CONTENTS**
The following table, including footnotes, sets forth information concerning Ms. Beck's frozen SERP benefits during fiscal year 2025:

---

| | | | | | |
|:---|:---|:---|:---|:---|:---|
| **Name** | **Age** | **Plan Name** | **Number of Years** <br>**Credited Service<sup>(1)</sup>** | **Present Value of** <br>**Accumulated** <br>**Benefits<sup>(2)(3)</sup>** | **Payments During** <br>**Last Fiscal Year**  |
| **Eileen L. Beck** | 63 | Frozen SERP | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$6000 | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$0 |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Years of Credited Service is based on the date that the SERP was frozen. Accordingly, there is a difference between the number of years of service that were credited to Ms. Beck for purposes of calculating the frozen SERP benefit and her actual 13 years of service with the Company.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The former GLT SERP was frozen as of December 31, 2019. Ms. Beck is vested in the benefit but no longer accrues service. Although the frozen SERP balance was incorporated into the NQDC plan, it is accounted for as a separate defined benefit plan and disclosed accordingly.

&nbsp;&nbsp;&nbsp;&nbsp;(3) For Ms. Beck, the amount reflected represents the present value of her frozen SERP balance under the GLT NQDC plan as of September 27, 2025. The present value of accumulated benefits was calculated using actuarially determined assumptions, including: (i) a discount rate of 5.46% (SERP II for U.S. GAAP accounting); (ii) Moody's Aa average interest crediting rates of 5.33% and 5.67% for November 2023 and 2024, respectively; and (iii) an assumed retirement age. The accrued value of Ms. Beck's total cash balance benefit as of September 27, 2025 was $5,280.

Given the hybrid nature of the legacy GLT NQDC plan, the frozen SERP balances in the NQDC plan are considered a defined benefit plan on the Company's financial statements and are reflected in the Pension Benefits Table above, and the Company contribution and participant deferral portions of the NQDC plan are considered a defined contribution plan and reflected in the Non-Qualified Deferred Compensation table below.

The legacy GLT NQDC plan coordinated with the 401(k) plan in November and December of 2024, whereby Ms. Beck received a company contribution of 7% on earnings in excess of the annual Code earnings limit. Ms. Beck did not elect to defer any base salary or bonus in this account during fiscal year 2025. Accounts in the NQDC plan attributable to Company contributions are credited with earnings based on the investment return of funds in which such participant accounts are invested on a notional basis. All legacy GLT NQDC plan benefits remain unfunded.

The following table, including footnotes, sets forth information concerning non-qualified deferred compensation benefits during 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Ms. Beck did not elect to defer any of her base or bonus into the legacy GLT NQDC plan for the months of November and December 2024.

&nbsp;&nbsp;&nbsp;&nbsp;(2) These amounts reflect the Company contributions to the NQDC plan for Ms. Beck in November and December 2024. The amounts shown as Registrant Contributions in 2025 are also reported as compensation to the NEOs in the All Other Compensation column in the Summary Compensation Table. The amounts represented as Registrant Contributions in 2025 do not reflect the frozen SERP balances, which are reflected in the Pension Benefits Table above.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Represents aggregate gains and losses on all accounts attributable to Company contributions and participant deferrals to the NQDC plan, based on the investment return of funds in which such participant accounts were invested on a notional basis. Interest on the frozen SERP balances is not included in the foregoing table, and, instead, is described in the Pension Benefits table above.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Amounts listed reflect the cumulative aggregate balance in all of Ms. Beck's accounts under the legacy GLT NQDC plan as of September 27, 2025. The amounts represented in Aggregate Balance at Last FYE column do not reflect the frozen SERP balances in the NQDC plan, which are reflected in the Pension Benefits Table above.

## Potential Payments upon Termination or Change in Control

#### Executive Severance Plan
Payments made to a NEO upon involuntary termination by the Company without cause are made in accordance with the Company's Executive Severance Plan or employment agreement (if applicable). Under the Company's Executive Severance plan, eligible NEOs receive CIC benefits. The Compensation Committee believes these arrangements serve as an incentive for the NEOs to act in the interest of shareholders in the event of a CIC, without regard to personal risks related to their continued employment resulting from a CIC. The CIC terms provide for severance and other benefits to be paid to the NEOs upon a qualifying CIC.

#### Change in Control Agreements and Double-Trigger Equity Vesting
Each NEO is a participant in the Company's Executive Severance Plan. Under the CIC agreements, each NEO's employment with the Company will continue for two years from the date of a CIC (as defined below) or each NEO will become entitled to severance payments and benefits upon termination under certain conditions within such two-year period. During such two-year period, the NEO will continue in a position with at least equal responsibilities and title as the position held prior to the CIC, without experiencing a material change in geographic location, and will receive compensation and benefits from the Company at least equal to those paid prior to the CIC.

Under the Plan, **CIC** means:

&nbsp;&nbsp;&nbsp;&nbsp;a) any individual, group or entity (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (other than the Company, its Subsidiaries, a trustee or other fiduciary holding securities under any employee benefit plan of the Company or an Affiliate, an underwriter temporarily holding securities pursuant to an offering of such securities, or any entity directly or indirectly owned by the shareholders of the Company in substantially the same proportions as their ownership of the Company) (a "Person") which acquires beneficial ownership (within the meaning 3 of Rule 13d-3 promulgated under the Exchange Act), directly or indirectly, of securities of the Company which, together with securities already held by such Person, represents 20% or more of the combined voting power of the Company's then outstanding securities, excluding any Person who becomes such a beneficial owner in connection with a transaction described in subsection (c)(i) below;

&nbsp;&nbsp;&nbsp;&nbsp;b) the following individuals cease for any reason to constitute a majority of the number of directors then serving on the Board: individuals who, on the Effective Date, constitute the Board and any new director whose appointment or election by the Board or nomination for election by the Company's shareholders was approved or recommended by a vote of at least a majority of the directors then still in office who either were directors on the Effective Date or whose appointment, election or nomination for election was previously so approved or recommended;

&nbsp;&nbsp;&nbsp;&nbsp;c) there is consummated a merger or consolidation of the Company or any direct or indirect Subsidiary of the Company with any other corporation, other than (i) a merger or consolidation which results in the directors of the Company immediately prior to such merger or consolidation continuing to constitute at least a majority of the Board, the surviving entity or any parent thereof, or (ii) a merger or consolidation effected to implement a recapitalization of the Company (or similar transaction) in which no Person is or becomes the beneficial owner, directly or indirectly, of securities of the Company (not including in the securities beneficially owned by such Person any securities acquired directly from the Company or its Affiliates) representing 50% or more of the combined voting power of the Company's then outstanding securities; or

&nbsp;&nbsp;&nbsp;&nbsp;d) the shareholders of the Company approve a plan of complete liquidation or dissolution of the Company or there is consummated an agreement for the sale or disposition by the Company of all or substantially all of the Company's assets, other than a sale or disposition by the Company of all or substantially all of the Company's assets to an entity, at least 50% of the combined voting power of the voting securities of which are owned by shareholders of the Company in substantially the same proportions as their ownership of the Company immediately prior to such sale.

#### **TABLE OF CONTENTS**

#### Tax Gross-Up Payments
Magnera CIC benefits do not include any tax gross-up provisions for excise taxes imposed under the Code.

#### "Double-Trigger" Provisions
The Company's equity grant agreements include "double-trigger" provisions that accelerate vesting in the event of a CIC if the executive is terminated without "cause" or resigns with "good reason" (each as defined in the Executive Severance Plan). The Compensation Committee believes that the double-trigger provision ensures continuity of management during mergers and acquisitions and assists with retaining key executives, ultimately benefiting shareholders.

The following table describes how each element of the NEO's post-employment compensation would be treated in the event of termination, with and without a CIC. The description of benefits upon termination or CIC for each NEO is only a general description of the existing arrangements as of September 27, 2025.

#### **TABLE OF CONTENTS**
The following table, including the footnotes that follow, describes the potential estimated payments to the NEOs upon termination of employment or due to a CIC of the Company as if such termination or CIC occurred on September 27, 2025. The tables below merely illustrate the impact of a hypothetical termination of employment or CIC. The actual amounts to be paid can only be determined at the time of such NEO's separation from the Company and/or CIC.

&nbsp;&nbsp;&nbsp;&nbsp;(1) In the event of an involuntary termination without cause, cash severance is equal to 12 months' base salary and target bonus. In the event of an involuntary termination without cause or for good reason in connection with a CIC, cash severance is equal to 24 months' base salary and target bonus.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Represents prorated bonus payment for the year of termination, valued at target.

&nbsp;&nbsp;&nbsp;&nbsp;(3) The values above represent awards for which full or partial vesting occurs upon termination as a result of involuntary termination without cause, death, disability or retirement, as applicable. The values are calculated (a) based on the closing price of $11.03 of the Company's common stock on September 26, 2025, and (b) as if death, disability or retirement had occurred on September 27, 2025. For CIC, the value assumes vesting (as determined under applicable award agreements) on September 27, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Assumes achievement of a target performance level at the end of the performance period.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Based on current type of coverage and premium levels.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Amounts reflect the application of the Company's Section 280G best-net cutback provision. For Messrs. Begle and Manroa and Ms. Beck, total parachute payments exceed their respective Section 280G limits; therefore, payments are reduced only to the extent necessary to provide a greater after-tax benefit than would be received without the reduction. No cutback applies if the executive would be in a better after-tax position receiving the full payments subject to excise tax, or if the executive is below the Section 280G limit.

The following information is presented to disclose the relationship between Compensation Actually Paid ("CAP"), as calculated under applicable SEC rules, and the financial performance of the Company. As required by SEC rules, the table presented below discloses CAP for (i) the Company's principal executive officer ("PEO") and (ii) the Company's NEOs other than the PEO (the "non-PEO NEOs"), on an average basis, for the fiscal year 2025.

The methodology for calculating amounts presented in the columns "PEO CAP" and "Non-PEO NEOs Average CAP" is provided in the footnotes to the table, and includes details regarding the amounts that were deducted from, and added to, the Summary Compensation Table ("SCT") totals to arrive at the values presented for CAP. A narrative discussion of the relationship between CAP and the Company performance measures (i) listed in the table and (ii) that the Company has deemed most important in linking CAP during 2025 to Company performance is also presented below.

Consistent with SEC rules, Magnera has identified Adj. EBITDA<sup>(4)</sup> as its "Company-Selected Measure." Magnera believes that this measure represents the most important financial performance measure used to link CAP to Company performance. Adj. EBITDA is a key component of Magnera's compensation program, as described in the CD&A.

Compensation decisions at Magnera are made independently of the Pay versus Performance ("PvP") disclosure requirements and this disclosure is intended to be supplemental to, not in replacement of, the compensation program objectives and strategy discussed in the CD&A. For information related to how the Compensation Committee assessed Magnera's performance and established compensation for the NEOs, see the "Executive Compensation" section of this proxy statement.

&nbsp;&nbsp;&nbsp;&nbsp;(1) The PEO reported in fiscal year 2025 is Curtis L. Begle.

&nbsp;&nbsp;&nbsp;&nbsp;(2) The non-PEO NEOs reported in fiscal year 2025 are James Till, Tarun Manroa, David Parks, and Eileen L. Beck.

&nbsp;&nbsp;&nbsp;&nbsp;(3) Amounts reported in this column represent returns on an initial $100 investment in the S&P Small Cap 600 Materials Index, which was utilized as the Company's peer group for purposes of calculating peer group total shareholder return included in this table pursuant to Item 201(e) of Regulation S-K.

&nbsp;&nbsp;&nbsp;&nbsp;(4) Adj. EBITDA is a non-GAAP measure that is reconciled to the nearest GAAP measure in "Annex A" of this proxy statement.

&nbsp;&nbsp;&nbsp;&nbsp;(5) CAP, as required under SEC rules, reflects adjustments to the value of unvested and vested equity awards during the years shown in the table based on year-end stock prices, various accounting valuation assumptions, and projected performance modifiers but does not reflect actual amounts paid out for those awards. CAP generally fluctuates due to stock price achievement and varying levels of projected and actual achievement of performance goals. Valuations calculated on such dates are determined in accordance with the Company's methodology used for financial reporting purposes. Equity awards issued by the Company during the covered periods are subject to certain market conditions and have been valued using a Monte Carlo simulation where applicable.

#### Relationship Between Compensation Actually Paid and Performance Measures
In accordance with the SEC's rules, the following section describes the relationship between CAP and the Company's performance metrics set forth in the table above for fiscal year 2025:

&nbsp;&nbsp;&nbsp;&nbsp;• **Total Shareholder Return ("TSR"):** As noted in the above table, Magnera's TSR was outperformed by the peer group, which is comprised primarily of larger, more established companies with market capitalization higher than that of a newly formed company like Magnera.

&nbsp;&nbsp;&nbsp;&nbsp;• **Adj. EBITDA:** Fiscal year 2025 represents Magnera's first year of standalone operations following the Transaction, and therefore no prior-year EBITDA results are available for comparison. Magnera generated Adj. EBITDA of $354 million for fiscal year 2025. Executive compensation for fiscal year 2025 was established at the time of the Transaction and was based on the Company's expected EBITDA performance as reflected in the Transaction-related plan, rather than on reported fiscal 2024 results, which were not available at the time.

&nbsp;&nbsp;&nbsp;&nbsp;• **Net Income:** Net Income (calculated in accordance with GAAP) was negative for fiscal year 2025 and does not correlate with CAP for the fiscal year presented. The Company does not use net income to determine compensation levels or incentive plan payouts.

Note that the Company was formed in November 2024; no year-over-year comparison is available for prior periods.

#### Tabular List of Most Important Performance Measures
Our executive compensation programs are designed to ensure alignment between executive pay, business performance and shareholders. The following table sets forth an unranked list of the most important financial performance measures, including the Company-Selected Measure, used by the Company to link CAP for all NEOs to Company performance for the fiscal year 2025.

| CEO Pay Ratio  | ![](logo_magnerax2.jpg) |

---

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Item 402(u) of Regulation S-K, we are providing information about the relationship between the annual total compensation of our median employee and the annual total compensation of Mr. Begle, the CEO serving in position on the date selected for identifying the median employee. For 2025, our ratio was estimated as follows:

---

| | |
|:---|:---|
| **Name** | **Annual Total Compensation<sup>(1)</sup>**  |
| CEO (Actual) | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$9792264  |
| CEO (Annualized)<sup>(2)</sup> | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$7785883  |
| Median Employee | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;$42258  |
| **CEO Pay Ratio (Actual)** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**232:1**  |
| **CEO Pay Ratio (Annualized)<sup>(2)</sup>** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**184:1** |

---

&nbsp;&nbsp;&nbsp;&nbsp;(1) Annual total compensation includes compensation for the CEO reported in the Summary Compensation Table and the market-competitive compensation and benefits for the median employee.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Reflects illustrative annualized compensation to represent the true pay ratio excluding the impact of any one-time special compensation elements.

The median employee was determined using the methodology outlined below:

&nbsp;&nbsp;&nbsp;&nbsp;• The Company initially identified its median employee at the time of the Transaction and revalidated this determination as of September 1, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;• Considered all employees throughout our global operations.

&nbsp;&nbsp;&nbsp;&nbsp;• Selected base salary or wages, overtime, premium pay, and short-term incentives as the most appropriate measure of compensation.

&nbsp;&nbsp;&nbsp;&nbsp;• Using this methodology, we determined the appropriate median employee to be a full-time employee in Germany. For purposes of this determination, we applied the appropriate exchange rate to U.S. dollars of the average exchange rate for September 2025.

We calculated the elements of the median employee's compensation and the CEO's compensation for fiscal year 2025 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K. The above pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of the Regulation S-K.

In making this pay ratio disclosure, other companies may use different assumptions, estimates, and methodologies; as a result, the following information may not be directly comparable to the information provided by other companies in our peer group or otherwise.

| Certain Relationships <br>and Related Transactions  | ![](logo_magnerax2.jpg) |

---

#### Related Persons Transactions Policy
The NCG Committee (or its Chair, under some circumstances) will review the relevant facts of all proposed Related Person transactions and either approve or disapprove of the entry into the Related Person transaction.

For purposes of this review, as defined in the NCG Committee Charter, an "Interested Transaction" is any transaction, arrangement, or relationship (or any series of similar transactions, arrangements, or relationships) involving an amount that is at least $120,000, and in which the Company was, is, or will be a participant, and in which any Related Person had, has, or will have a direct or indirect material interest. A "Related Person" is generally any person who is, or at any time since the beginning of the Company's last fiscal year was, (i) a director or executive officer of the Company or a nominee to become a director of the Company; (ii) any person who is known to be the beneficial owner of more than 5% of any class of the Company's voting securities; (iii) any immediate family member of any of the foregoing persons; or (iv) any firm, corporation, or other entity in which any of the foregoing persons is employed or is a general partner or principal or in a similar position, or in which such person has a 5% or greater beneficial ownership interest. There were no Interested Transactions during 2025.

According to the Board's Related Persons Transaction Policy, Interested Transactions are approved only if they are determined to be in, or not inconsistent with, the best interests of the Company and its shareholders. No director may participate in any consideration or approval of an Interested Transaction in which he or she, or any of his or her immediate family members or related entities, is the Related Person.

If an Interested Transaction that has not been previously approved or ratified is identified, the NCG Committee, or its Chair, will promptly consider all the relevant facts. If the transaction is ongoing, the NCG Committee will consider all options and may ratify, amend, or terminate the Interested Transaction. If the Interested Transaction was completed, the NCG Committee will consider if rescission of such transaction is appropriate and if disciplinary action is warranted. The NCG Committee will review all ongoing Interested Transactions on an annual basis to determine whether to continue, modify, or terminate the Interested Transaction.

In reviewing the relevant facts related to all proposed Interested Transactions, the NCG Committee, or its Chair, will take the following considerations into account, along with other factors it deems appropriate:

&nbsp;&nbsp;&nbsp;&nbsp;• the benefits to the Company of the transaction

&nbsp;&nbsp;&nbsp;&nbsp;• the impact on a director's independence, in the event the Related Person is a director, an immediate family member of a director, or an entity in which a director is a partner, shareholder, or executive officer

&nbsp;&nbsp;&nbsp;&nbsp;• the availability of other sources for comparable products or services

&nbsp;&nbsp;&nbsp;&nbsp;• the terms of the transaction

&nbsp;&nbsp;&nbsp;&nbsp;• the terms available from unrelated third parties or to employees generally

To the extent that the NCG Committee, or its Chair, needs additional information to make an informed decision regarding a proposed Interested Transaction, the NCG Committee, or its Chair, may consult with management or other members of the Board.

| Report of the <br>Audit Committee  | ![](logo_magnerax2.jpg) |

---

The Audit Committee has reviewed and discussed the Company's audited consolidated financial statements for the fiscal year ended September 27, 2025 with the Company's management and its independent registered public accounting firm. The Company's management has advised the Audit Committee that such audited consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America.

The Audit Committee has discussed with Ernst & Young, the Company's independent registered public accounting firm, the matters required to be discussed by Auditing Standard No. 1301, "Communications with Audit Committees," as issued by the Public Company Accounting Oversight Board. The Audit Committee has also discussed with Ernst & Young its independence from the Company and its management. The Audit Committee has received a letter and written disclosures from Ernst & Young required by applicable requirements of the Public Company Accounting Oversight Board, disclosing all relationships between Ernst & Young and its related entities and the Company. In addition to the information provided by Ernst & Young, the Audit Committee considered the level of non-audit and tax services provided by Ernst & Young in determining that it was independent. Based on the review and discussions described above, the Audit Committee recommended to the Company's Board that the Company's audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended September 27, 2025, for filing with the SEC.

*The foregoing Report of the Audit Committee ("Report") does not constitute soliciting material and should not be deemed filed or incorporated by reference into any other filing of the Company under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates the Report by reference therein.*

| Frequently Asked <br>Questions ("FAQs")  | ![](logo_magnerax2.jpg) |

---

#### Why did I receive these materials?
As a shareholder, the Company is soliciting your vote on matters to be considered at the Annual Meeting. This proxy statement and accompanying proxy card or, in some cases, a Notice of Internet Availability of Proxy Materials (the "Notice"), were first sent or given to shareholders on or about January 14, 2026.

#### Why did I receive a Notice of Internet Availability of proxy materials?
Under the rules of the SEC, we are furnishing proxy materials to certain of our shareholders on the Internet, rather than mailing printed copies to those shareholders. Distribution by Internet reduces the environmental impact of our Annual Meeting, expedites shareholders' receipt of the proxy materials, and lowers our costs. If you received a Notice by mail, you will not receive a printed copy of the proxy materials unless you request one as instructed in that Notice. Instead, the Notice will instruct you as to how you may access and review the proxy materials on the Internet. If you received a Notice by mail and would like to receive a printed copy of our proxy materials, please follow the instructions included in the Notice.

#### When and where is the Annual Meeting?
The Annual Meeting will be held on Monday, March 9, 2026, at 9:00 a.m. Eastern Time via live audio cast on the Meeting Website, which is www.virtualshareholdermeeting.com/MAGN2026. There will not be a physical location for the Annual Meeting, and you will not be able to attend the meeting in person. To virtually attend the Annual Meeting, visit the Meeting Website and enter the 16-digit control number found on your proxy card, voting instruction form, or Notice.

#### Who is soliciting this proxy?
Solicitation of proxies is made on behalf of the Company. In addition to the solicitation by electronic communications and/or mail, directors, officers, regular employees and others may also, without additional compensation, solicit proxies personally or by telephone or other means of electronic communication. Proxies will be solicited on behalf of the Company by the Company's directors, director nominees, and certain executive officers and other employees of the Company.

#### Who is entitled to vote?
Shareholders of record as of the close of business on the Record Date (December 31, 2025) may vote at the Annual Meeting. At the close of business on the Record Date, there were 35,850,147 shares of the Company's common stock outstanding and eligible to vote at the Annual Meeting.

#### What is the difference between a registered shareholder and a beneficial owner?
If your shares are registered in your name in the records of our transfer agent, Computershare Limited, you are a "registered shareholder," also sometimes called a shareholder of record. If you are a registered shareholder, we sent the Notice directly to you.

If your shares are held in the name of your broker, bank, or other nominee, your shares are held in "street name" and you are considered the "beneficial owner." The Notice should have been forwarded to you by your broker, bank, or other nominee, who is considered the shareholder of record for those shares. As the beneficial owner, you have the right to direct your broker, bank, or other nominee how to vote your shares by following the voting instructions included in the mailing.

Page \| 61<br>

------

#### **TABLE OF CONTENTS**

#### How do I vote?
If you are a registered shareholder, meaning you hold your shares in your own name as a holder of record, you may vote during the Annual Meeting on the Meeting Website or submit your proxy ahead of the meeting by phone, internet, or mail:

---

| | |
|:---|:---|
| ![](ny20057004x1_telephone.jpg)<br>| Call 1-800-690-6903  |
| ![](ny20057004x1_internet.jpg)<br>| Visit www.proxyvote.com  |
| ![](ny20057004x1_mail.jpg)<br>| Complete and sign the enclosed proxy card and return it promptly in the enclosed envelope (requiring no postage if mailed in the United States). Please make certain you mark, sign, and date your proxy card prior to mailing. All valid proxies received and not revoked prior to the Annual Meeting will be voted in accordance with your instructions. |

---

Proxies must be received by 11:59 p.m., Eastern Time on March 8, 2026. The method or timing of your proxy vote will not limit your right to vote at the Annual Meeting if you attend the Annual Meeting.

If you are a beneficial owner, meaning your shares are held by a brokerage firm, bank, or other nominee (i.e., in "street name"), you should receive directions from your bank or broker that you must follow in order to vote your shares.

**Will my shares be voted if I do not sign and return my proxy card or follow the instructions to vote my shares on the Notice?**

The Board has appointed Curtis L. Begle and Jill L. Urey, or either of them (the "Proxy Holders") with power of substitution, to vote all properly-executed proxies received from shareholders entitled to vote at the Annual Meeting or at any adjournment, continuation, or postponement of the Annual Meeting.

If a shareholder of record signs and returns the accompanying proxy card, but does not make any selections, the Board's appointed Proxy Holders will have discretion to vote the shareholder's shares on behalf of the shareholder at the Annual Meeting as recommended by the Board.

If a beneficial owner of shares does not provide the bank or broker holding such shares with specific voting instructions, under the rules of the NYSE, the shareholder's bank or broker may generally vote on "routine" matters but cannot vote on "non-routine" matters. "Broker non-votes" occur when a beneficial owner of shares held in street name fails to provide instructions to the broker, bank, or other holder of record as to how to vote on matters deemed non-routine.

If a shareholder's broker, bank, or other nominee does not receive the shareholder's instructions on how to vote the shareholder's shares on a non-routine matter, the shareholder's broker, bank, or other nominee will inform the Company it does not have the beneficial owner's authority to vote on the non-routine matter. In these cases, the broker, bank, or other nominee can register your shares as being present at the Annual Meeting for purposes of determining the presence of a quorum but will not be able to vote on those matters for which specific authorization is required under the NYSE rules. We encourage beneficial shareholders to provide voting instructions to the broker, bank, or other nominee holding their shares by carefully following the instructions in the Notice provided by the shareholder's broker, bank, or other nominee.

#### How do I change my vote or revoke my proxy if I wish to do so?
Shareholders of record can revoke their proxy at any time before their shares are voted by: (1) delivering a written revocation of their proxy to the Company's Corporate Secretary; (2) submitting a later-dated proxy (or voting instruction form if they hold their shares in street name); or (3) voting on the Meeting Website during the Annual Meeting. Shareholders who are beneficial owners should follow the instructions provided by their respective broker or bank to change their vote.

#### **TABLE OF CONTENTS**

#### What is the required quorum to hold this Annual Meeting?
As of the Record Date, 35,850,147 shares of the Company's common stock were outstanding and entitled to vote. A quorum will consist of a majority of the total voting rights of all shareholders entitled to vote as of the Record Date, whether present by virtual attendance or represented by proxy.

Abstentions and "broker non-votes" are counted as present and entitled to vote for purposes of determining a quorum. A "broker non-vote" occurs when a broker, bank, or other nominee holding shares for a beneficial owner does not vote on a particular matter because the broker or bank does not have discretionary voting authority to vote on the proposal, and the beneficial owner has not provided voting instructions.

#### Who may virtually attend the Annual Meeting and what else is required for admittance?
Only shareholders of the Company's common stock on the Record Date may attend the Annual Meeting. To be admitted to the Meeting Website, you must enter the 16-digit control number found on your proxy card, voting instruction form, or Notice. You may vote your shares and ask questions during the Annual Meeting by following the instructions available on the Meeting Website. We encourage you to access the Meeting Website prior to the start time of the Annual Meeting to familiarize yourself with the virtual platform and ensure you can hear the streaming audio. Online access to the Meeting Website will be available starting at 8:45 a.m., Eastern Time, on March 9, 2026.

#### May shareholders ask questions during the Annual Meeting?
Yes. If you wish to submit a question, you may do so in two ways:

#### In Advance:

#### Enter your 16-digit Control Number at www.proxyvote.com and select "Submit a Question for Management"

#### During the Meeting:

#### Type your question in the Question & Answer ("Q&A") box on the Virtual Meeting Website
After the formal business of the Annual Meeting has concluded and adjourned, the chair of the Annual Meeting will answer questions from shareholders during the designated Q&A period of the Annual Meeting agenda. In order to give as many shareholders as possible the opportunity to ask questions, we ask that questions are succinct and cover only one topic per question. Up to three minutes will be allocated to read and respond to each question that we are able to answer during the Annual Meeting. The Q&A session will continue until all relevant questions have been answered, subject to time constraints.

Shareholders' views, constructive comments, and criticisms are welcome, but the Company will not address questions that are:

&nbsp;&nbsp;&nbsp;&nbsp;• Irrelevant to the business of the Company or to the business of the Annual Meeting

&nbsp;&nbsp;&nbsp;&nbsp;• Related to material non-public information of the Company

&nbsp;&nbsp;&nbsp;&nbsp;• Repetitious of prior questions or statements from others

&nbsp;&nbsp;&nbsp;&nbsp;• Derogatory references to individuals that are in bad taste

&nbsp;&nbsp;&nbsp;&nbsp;• Related to personal grievances

&nbsp;&nbsp;&nbsp;&nbsp;• In furtherance of a shareholder's personal or business interests, which are not matters of interest to shareholders generally

&nbsp;&nbsp;&nbsp;&nbsp;• Out of order or not otherwise suitable for the conduct of the Annual Meeting

If there are any matters of individual concern to a shareholder or questions that are not answered, they may be raised separately after the Annual Meeting by contacting the Company's Investor Relations at ir@magnera.com.

#### Who pays for the proxy solicitation related to the Annual Meeting?
The Company pays the cost of preparing, printing, assembling, and sending this proxy statement and other proxy solicitation materials. The Company will also reimburse brokers and other custodians, nominees, and fiduciaries for their reasonable out-of-pocket expenses for forwarding the proxy statement and other proxy solicitation materials to beneficial

owners. In addition to the solicitation of proxies by mail or via electronic means, some of our directors, officers, other employees, and agents may solicit proxies personally, by telephone, text message, email, and by other means. The officers and directors who may solicit proxies personally receive no additional compensation for any solicitation activities.

#### How many votes are needed to elect a director and how are votes counted?
Under Pennsylvania law, unless a company's articles of incorporation or bylaws provide otherwise, directors are elected by a plurality of the votes cast. Our Articles of Incorporation provide that in an election of directors that is not a contested election, a director nominee shall be elected to the Board if the votes cast for such nominee's election exceed the votes cast against such nominee's election. Proposal 1: Election of Directors is not considered to be a routine matter, and brokers will not be entitled to vote on this proposal unless beneficial owners provide voting instructions. Abstentions and broker non-votes will not be considered as votes cast.

A director nominee will be elected to our Board if the votes cast "FOR" such director nominee exceed the votes cast "AGAINST" them. As required by our Corporate Governance Principles, each of the nine director nominees has submitted an irrevocable resignation as a director in advance. For more information regarding the election of directors and the resignation procedure, see the discussion of the "Resignation and Majority Voting Policy" in the "Corporate Governance and Board of Directors" section of this proxy statement.

#### How many votes are needed for proposals 2 and 3 to be approved and how are votes counted?
The Company is incorporated in the Commonwealth of Pennsylvania, and our shares are listed on the NYSE. As a result, the Pennsylvania Business Corporation Law and NYSE listing standards govern the voting standards applicable to actions taken by our shareholders.

Under our Bylaws, the affirmative vote of a majority of the votes cast in person or by proxy at the Annual Meeting by the shareholders entitled to vote thereon is required to approve proposals 2 and 3 set forth on the proxy card. Abstentions and broker non-votes are counted for purposes of determining the presence or absence of a quorum but are not considered votes cast under Pennsylvania law and our Bylaws.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Under NYSE rules, proposal 2 is considered a "routine" proposal on which brokers are permitted to vote in their discretion, even if the beneficial owners do not provide voting instructions. However, proposal 3 is not considered a routine matter and brokers will not be entitled to vote on this proposal unless beneficial owners provide voting instructions. Accordingly, broker non-votes will not be counted toward the tabulation of votes on proposal 3.

#### How may a shareholder recommend or nominate a candidate to sit on the Board of Directors?
A shareholder may recommend director nominees for consideration by the NCG Committee. Shareholder recommendations for director nominees will receive the same consideration by the NCG Committee that all other director nominee recommendations receive. If a shareholder wishes to recommend a nominee for director, the shareholder must submit such recommendation in writing, together with any supporting materials deemed appropriate, to the Company's Secretary.

The Bylaws establish an advance notice procedure for shareholders to make nominations of candidates for election as directors before an annual meeting of shareholders. Notice of such nomination, including all of the information set forth in

The Company will continue to include a separate proxy card for each registered shareholder account.

If you (1) are currently receiving multiple copies and wish to participate in "householding" for future annual meetings of shareholders; or (2) are currently "householding" and wish to receive separate copies of Annual Reports or proxy statements for future annual meetings, please notify our Investor Relations department as described above.

(1)Supplemental financial measures that are not required by, or presented in accordance with, accounting principles generally accepted in the United States ("GAAP"). These non-GAAP financial measures should not be considered as alternatives to operating or net income or cash flows from operating activities, in each case determined in accordance with GAAP. Comparable basis measures exclude the impact of currency translation effects and acquisitions. These non-GAAP financial measures may be calculated differently by other companies, including other companies in our industry, limiting their usefulness as comparative measures. Management believes that Adjusted EBITDA and other non-GAAP financial measures are useful to our investors because they allow for a better period-over-period comparison of operating results by removing the impact of items that, in management's view, do not reflect our core operating performance. We define "Post-merger free cash flow" as cash flow from operating activities, less pre-merger free cash flow, less net additions to property, plant, and equipment. We believe free cash flow is useful to an investor in evaluating our liquidity because free cash flow and similar measures are widely used by investors, securities analysts, and other interested parties in our industry to measure a company's liquidity. We believe post-merger free cash flow is also useful to an investor in evaluating our liquidity as it can assist in assessing a company's ability to fund its growth through its generation of cash and as pre-merger cash flow is not indicative of our current structure and operations.

We also use Adjusted EBITDA and comparable basis measures, among other measures, to evaluate management performance and in determining performance-based compensation. Adjusted EBITDA is a measure widely used by investors, securities analysts, and other interested parties in our industry to measure a company's performance. We also believe these measures are useful to an investor in evaluating our performance without regard to revenue and expense recognition, which can vary depending upon accounting methods.

(2)Includes restructuring, business optimization and other charges and YTD balance also includes $19 million of transaction compensation

(3)Consists of estimated parent-allocated charges for the period prior to merger which is required by GAAP as part of the carve-out financial statement process

(4)Includes a $4 million and $16 million inventory step-up charge related to Glatfelter merger in the quarter and YTD, respectively, and other non-cash charges

(5)Includes stock compensation expense and equipment disposals
