Item 1.01.

Entry into a Material Definitive Agreement.

Credit Agreement

On January 22, 2025, the Company entered into a commitment letter (the “Commitment Letter”) with Rio Tinto plc, pursuant to which Rio Tinto plc (or an affiliate thereof) has committed to provide Arcadium Lithium Financing IRL Designated Activity Company with (i) a first lien secured term loan facility in an aggregate principal amount of $200.0 million (the “Pari Passu Term Loan Facility”, and the loans thereunder, the “Pari Passu Term Loans”) and (ii) a second lien secured term loan facility in an aggregate principal amount of $300.0 million (the “Junior Term Loan Facility”, and together with the Pari Passu Term Loan Facility, the “Term Loan Facilities”; and the loans thereunder, the “Junior Term Loans”, and together with the Pari Passu Term Loans, the “Term Loans”). The availability of the Term Loan Facilities is subject to the satisfaction of certain conditions precedent set forth in the Commitment Letter.

The obligations under the Term Loan Facilities will be guaranteed by the same entities that guarantee the obligations under the amended and restated credit agreement, dated as of September 1, 2022 (as amended, restated, amended and restated, supplemented and/or otherwise modified from time to time prior to the date hereof, the “Existing Revolving Credit Facility”), by and among the Company, certain subsidiaries of the Company as guarantors, the lenders and issuing banks from time to time party thereto and Citibank, N.A. as administrative agent. In addition, (i) the Pari Passu Term Loan Facility will be secured by first-priority liens on the same assets that secure the Existing Revolving Credit Facility and (ii) the Junior Term Loan Facility will be secured by second-priority liens on the same assets that secure the Existing Revolving Credit Facility.

The proceeds of the Term Loans may be used for certain capital expenditures payments of the Company and its subsidiaries. The principal amount of the Term Loans, together with accrued and unpaid interest thereon, will be due and payable on September 1, 2027. The Term Loans may be prepaid by the Company at any time in whole or in part, subject to certain minimum thresholds, without penalty or premium, subject to customary breakage costs for certain types of loans.

The Term Loans will bear interest at adjusted term SOFR (defined as the forward-looking SOFR term rate published by CME Group Benchmark Administration Limited plus 0.10% per annum subject to a floor of zero) plus an applicable margin, as determined in accordance with the provisions of the definitive documentation for the Pari Passu Term Loans (the “Pari Passu Credit Agreement”) and the Junior Term Loans (the “Junior Credit Agreement”, and together with the Pari Passu Credit Agreement, the “Credit Agreements”). Interest will be payable on the last day of an interest period.

The Credit Agreements will contain customary representations and warranties and customary affirmative and negative covenants including, among other requirements, limitations on indebtedness, liens, fundamental changes, advances, investments and loans, sale of assets, sale and leaseback transactions, restricted payments, nature of business, modification of constituent documents, transactions with affiliates, and negative pledges. Further, the Credit Agreements will contain the same financial covenants as the Existing Revolving Credit Facility, which will require the maintenance of a maximum leverage ratio and a minimum interest coverage ratio.

The Credit Agreements will contain events of default that include, among others, non-payment of principal, interest or fees, breach of covenants, inaccuracy of representations and warranties, cross defaults to certain other indebtedness, bankruptcy and insolvency events, material judgments, and events constituting a change of control. Upon the occurrence and during the continuance of an event of default, the lender may accelerate the obligations under the applicable Credit Agreement.
