Pay vs Performance Disclosure

Pay vs Performance Disclosure, Table

	Pay Versus Performance

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⁽⁴⁾ 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.

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.

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.

Equity Valuation Assumption Difference, Footnote

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.

Compensation Actually Paid vs. Total Shareholder Return

• 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.

Compensation Actually Paid vs. Net Income

• 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.

Compensation Actually Paid vs. Company Selected Measure

• 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.

Total Shareholder Return Vs Peer Group

• 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.
