Exhibit 99.1

UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

On February 16, 2024, Ball Corporation (“Ball” or the “Company”) completed the previously announced divesture of its Aerospace business segment (the “Business”) to BAE Systems, Inc. (“BAE”) and, for the limited purposes set forth therein, BAE Systems plc, for a purchase price of $5.6 billion, subject to working capital adjustments and other customary closing adjustments under the terms of the Agreement (the “Divestiture” or the “Transaction”). The Transaction represents a strategic shift and therefore, beginning with Ball’s quarterly report on Form 10-Q for the period ending March 31, 2024, the Business’ historical financial results for periods prior to the Divestiture will be reflected in the Company’s consolidated financial statements as discontinued operations for all periods presented.

The following unaudited pro forma condensed consolidated balance sheet as of September 30, 2023 is presented as if the Divestiture had occurred on that day. The unaudited pro forma condensed consolidated statements of earnings for the nine months ended September 30, 2023, and for each of the three years ended December 31, 2022, 2021, and 2020, are presented as if the Divestiture occurred on January 1, 2020.

The unaudited pro forma condensed consolidated financial statements (the “Pro Formas”) are based on the historical consolidated financial statements of Ball, and in the opinion of Ball management, all adjustments and disclosures have been prepared in accordance with Regulation S-X, Article 11. All adjustments shown are transaction accounting adjustments and do not reflect the potential uses of proceeds, synergies, or dis-synergies that may be derived in future periods. The Pro Formas are subject to the assumptions and adjustments described in the accompanying notes and are based on information presently available.

The Pro Formas are presented for illustrative purposes only and do not necessarily reflect the results of operations or the financial position of Ball that actually would have resulted had the Divestiture occurred at the dates indicated, nor project the results of operations or financial position of Ball for any future date or period. The Pro Formas and the accompanying notes should be read in conjunction with:

●

the audited consolidated financial statements and accompanying notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Ball’s Form 10-K for the year ended December 31, 2022 and

●

the unaudited condensed consolidated financial statements and accompanying notes and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in Ball’s Form 10-Q for the three and nine months ended September 30, 2023.

Notes to Unaudited Pro Forma Condensed Consolidated Financial Statements

(a)

Reflects the removal of the assets, liabilities and operations attributable to the Aerospace business, which were included in the Company’s historical financial statements. Historical tax expense attributed to the Aerospace business has been provided using the applicable statutory income tax rates in effect within the respective tax jurisdictions during the periods presented, adjusted for tax benefits associated with the U.S. federal research and development tax credit and the federal tax benefit of state and local taxes. The amounts are considered preliminary, and as such, actual results could materially differ from these estimates.

(b)

Reflects the Divestiture purchase price of $5.6 billion, that was subject to working capital adjustments and other customary closing adjustments under the terms of the Agreement, resulting in a cash payment from BAE to Ball at closing of $5.47 billion. The use of the proceeds from the Transaction are not reflected in the unaudited pro forma condensed consolidated balance sheet because such uses are not contractually committed or estimable.

(c)

Reflects the estimated income tax impact of the pro forma transaction accounting adjustments at the applicable statutory income tax rates in effect within the respective tax jurisdictions during the periods presented, adjusted for the federal tax benefit of state and local taxes.

(d)

Represents the estimated pre-tax gain resulting from the Divestiture of $4.8 billion, which is subject to final working capital adjustments and other customary closing adjustments under the terms of the Agreement. This also is the effect of the transaction accounting adjustments described in notes (b), (c), (e) and (f) on shareholders' equity.

(e)

Represents the accrual of additional estimated transaction and other associated costs incurred by Ball pursuant to the Divestiture that are not already reflected in the historical results. Total transaction and other associated costs related to the Transaction are estimated to be $85 million. These costs will not affect the Company’s income statement beyond 12 months after the disposal date. As of September 30, 2023, $19 million of such costs were already incurred and included as part of the historical results.

(f)

The Divestiture is structured as an asset sale for income tax purposes. The gain is estimated to increase current tax expense by $1.0 billion. In addition, $178 million of deferred tax assets are estimated to reverse in connection with the transaction. These adjustments reflect the income tax effects using the applicable enacted statutory income tax rates in effect within the respective tax jurisdictions during the period presented, adjusted for the federal tax benefit of state and local taxes. The amounts are considered preliminary, and as such, actual results could materially differ from these estimates.
