Item 1.01. Entry Into a Material Definitive Agreement.

On May 12, 2025, Ball Corporation, an Indiana corporation (the “Company”), entered into an underwriting agreement (the “Underwriting Agreement”) among the Company, the subsidiary guarantors party thereto (the “Guarantors”) and the several underwriters named therein (the “Underwriters”), in connection with the Company’s previously announced underwritten public offering (the “Offering”) of €850 aggregate principal amount of 4.250% Senior Notes due 2032 (the “Notes”). The Offering is expected to close on May 19, 2025, subject to customary closing conditions and other factors.

The Notes were offered pursuant to a prospectus, dated May 7, 2025, forming a part of the Company’s shelf registration statement on Form S-3 (Registration No. 333-287034), and a prospectus supplement, dated May 12, 2025.

The Underwriting Agreement includes customary representations, warranties, covenants and closing conditions. It also provides for customary indemnification by each of the Company, the Guarantors and the Underwriters against certain liabilities and customary contribution provisions in respect of those liabilities.

The Company intends to use the net proceeds from the Offering, together with cash on hand, for general corporate purposes, which may include the refinancing or repayment of debt, potential investments in strategic alliances and acquisitions, working capital, pension contributions or capital expenditures. Prior to the application of such proceeds, the Company intends to repay outstanding borrowings under its U.S. dollar revolver, without a reduction in commitment, using a portion of the net proceeds from the Offering, together with cash on hand. The exact allocation of such proceeds and the timing thereof is at the discretion of the Company’s management.

A copy of the Underwriting Agreement is attached hereto as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference herein. The above description of the material terms of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to such Exhibit.
