NEWMARKET CORP

1. Financial Statement Presentation

In the opinion of management, the accompanying consolidated financial statements of NewMarket Corporation and its subsidiaries contain all necessary adjustments for the fair presentation of, in all material respects, our consolidated financial position as of March 31, 2024 and December 31, 2023, our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the three months ended March 31, 2024 and March 31, 2023, and our cash flows for the three months ended March 31, 2024 and March 31, 2023. All adjustments are of a normal, recurring nature, unless otherwise disclosed. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the NewMarket Corporation Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the three month period ended March 31, 2024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2024. The December 31, 2023 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Unless the context otherwise indicates, all references to “we,” “us,” “our,” the “company,” and “NewMarket” are to NewMarket Corporation and its consolidated subsidiaries.

Supplier Finance Program

We offer our vendors a supplier finance program, which allows our vendors to receive payment from a third-party finance provider earlier than our normal payment terms would provide. NewMarket and its subsidiaries are not a party to any arrangement between our vendors and the finance provider, and there are no assets pledged as security or other forms of guarantees provided by NewMarket to the finance provider. For those vendors who opt to participate in the program, we pay the finance provider the full amount of the invoices on the normal due date. At both March 31, 2024 and December 31, 2023, the amount of confirmed invoices under the supplier finance program was not material.
