Pay vs Performance Disclosure, Table | PAY VERSUS PERFORMANCE As required by Section 953(a) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid and certain financial performance of the Company. For further information concerning the Company’s variable pay-for-performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to “Executive Compensation—Compensation Discussion and Analysis.” The following table shows the past three fiscal years’ total compensation for our Named Executive Officers (NEOs) as set forth in the “Summary Compensation Table,” the compensation actually paid to our NEOs, the company’s total shareholder return (TSR), the combined TSR of our selected peer group, our Net Income, and our Base EBITDA.

(5) The amounts reported in this column reflect the cumulative total stockholder return on our common stock for each of the last three fiscal years ended December 31, 2023, assume an investment of $100 on December 31, 2020, and the reinvestment of any dividends. ​ (6) The peer group used in this disclosure, the Dow Jones Container and Packaging Index, is the same peer group used in the Stock Performance Graph in Part II, Item 5 of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023. ​ (7) Base EBITDA is a non-GAAP financial measure which begins with Base operating profit, which excludes tax and interest and then adds back deductions for the cost of depreciation and amortization, adjusted for unbudgeted EBITDA related to acquisitions and divestitures in a given year. Base operating profit and Base EBITDA are non-GAAP financial measures. A reconciliation on how Base operating profit was calculated is provided in Appendix 1. As described in greater detail in “Executive Compensation—Compensation Discussion and Analysis,” Base EBITDA is one of the key metrics used to determine payout under the Company’s Performance-based Annual Cash Incentive program. |  |  |

Tabular List, Table | Financial Performance Measures As described in greater detail in “Executive Compensation—Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both the long-term and short-term incentive awards are selected based on an objective of incentivizing the NEOs to increase shareholder value. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows: • Base EBITDA; ​ Base EPS; ​ Return on Invested Capital (ROIC); and ​ Operating Cash Flow. |  |  |

Non-GAAP Measure Description | (7) Base EBITDA is a non-GAAP financial measure which begins with Base operating profit, which excludes tax and interest and then adds back deductions for the cost of depreciation and amortization, adjusted for unbudgeted EBITDA related to acquisitions and divestitures in a given year. Base operating profit and Base EBITDA are non-GAAP financial measures. A reconciliation on how Base operating profit was calculated is provided in Appendix 1. As described in greater detail in “Executive Compensation—Compensation Discussion and Analysis,” Base EBITDA is one of the key metrics used to determine payout under the Company’s Performance-based Annual Cash Incentive program. |  |  |
