Third Quarter Net Income of $111.2 Million and Earnings Per Share of $11.60
Nine Months Petroleum Additives Operating Profit of $404.0 Million
Year-to-date $71.9 Million Working Capital Improvement

NewMarket Corporation (NYSE:NEU) Chairman and Chief Executive Officer, Thomas E. Gottwald, released the following earnings report of the Company's operations for the third quarter and first nine months of 2023.

Net income for the third quarter of 2023 was $111.2 million, compared to net income of $63.2 million for the third quarter of 2022. Third quarter 2023 earnings per share increased to $11.60, up from $6.32 per share in the same period last year. For the first nine months of 2023, net income was $308.5 million, or $32.05 per share, compared to net income of $189.0 million, or $18.60 per share, for the first nine months of 2022.

Petroleum additives sales for the third quarter of 2023 were $663.7 million, compared to $692.7 million for the same period in 2022. Petroleum additives operating profit for the third quarter of 2023 was $139.8 million, compared to $83.0 million for the third quarter of 2022. The increase in operating profit was mainly due to selling prices, including favorable mix, as well as lower raw material costs, partially offset by lower shipments and higher operating costs. Shipments were down 7.7% between quarterly periods, with decreases in both lubricant additives and fuel additives shipments. When comparing the third quarter of 2023 to the same period in 2022, lubricant additives shipments were down in all regions except North America, while all regions except Europe reported decreases in fuel additives shipments.

Sales for the petroleum additives segment for the first nine months of 2023 were $2.0 billion, compared to $2.1 billion in 2022. Petroleum additives operating profit for the first nine months of 2023 was $404.0 million, compared to $261.1 million for the same period in 2022. The increase in operating profit was a result of selling prices, including favorable mix, partially offset by lower shipments and higher operating costs. Shipments decreased 13.5% when comparing the first nine months of 2023 to the same period in 2022, with decreases in both lubricant additives and fuel additives shipments in all regions except Europe, which reported an increase in fuel additives shipments.

Our shipments have been impacted the last several quarters by the overall global economic weakness and inventory rationalization that is affecting the chemical industry. We continue to be challenged by the ongoing inflationary environment impacting us, including our raw material and operating costs. During this period, we have remained focused on controlling operating costs, continuing our investment in technology, and managing our inventory levels, as well as our customer portfolio.

Overall, we are very pleased with the strong performance of our petroleum additives business during the first nine months of 2023. We continue to operate with low leverage and generated solid cash flows during this period. Our working capital improved by $71.9 million, we paid dividends of $63.5 million, and we made payments of $225.0 million on our revolving credit facility. In addition, we repurchased 119,075 shares of our common stock for $42.9 million. Our Net Debt to EBITDA ratio decreased to 1.1 as of September 30, 2023, a significant improvement over the December 31, 2022 ratio of 2.0.

We continue to make decisions to promote long-term value for our shareholders and customers, and we remain focused on our long-term objectives. We believe the fundamentals of how we run our business - a long-term view, safety-first culture, customer-focused solutions, technology-driven product offerings, and world-class supply chain capability - will continue to be beneficial for all our stakeholders.

Sincerely,

Thomas E. Gottwald

The Company has disclosed the non-GAAP financial measures EBITDA, Net Debt, and Net Debt to EBITDA, as well as the related calculations in the schedules included with this earnings release. EBITDA is defined as income from continuing operations before the deduction of interest and financing expenses, income taxes, depreciation (on property, plant and equipment) and amortization (on intangibles and lease right-of-use assets). Net Debt is defined as long-term debt, including current maturities, less cash and cash equivalents and marketable securities. Net Debt to EBITDA is defined as Net Debt divided by EBITDA for the rolling four quarters ended as of the specified date.
