Full Year Net Income of $279.5 Million and Earnings Per Share of $27.77

Petroleum Additives Full Year Operating Profit of $378.2 Million

Continued Focus on Margin Recovery and Cost Control

NewMarket Corporation (NYSE:NEU) Chairman and Chief Executive Officer, Thomas E. Gottwald, released the following earnings report of the Company's operations for the fourth quarter and full year of 2022.

Net income for the fourth quarter of 2022 was $90.5 million, or $9.26 per share. Net income for 2022 was $279.5 million, or $27.77 per share, compared to net income of $190.9 million, or $17.71 per share, for 2021.

Petroleum additives sales for the fourth quarter were $680.3 million and reached $2.8 billion for 2022, compared to $2.3 billion for 2021. Petroleum additives operating profit for the fourth quarter was $117.1 million and for 2022 was $378.2 million, compared to $281.1 million in 2021. For the year, the operating profit increase was mainly due to increased selling prices partially offset by higher raw material and operating costs. Shipments decreased 2.9% between periods, primarily due to decreases in lubricant additives shipments. Supply chain disruptions and new sanctions introduced during 2022 as a result of the Russia-Ukraine war were the primary contributors to the decline in shipments.

During 2022, we funded capital expenditures of $56.2 million and returned $291.8 million to our shareholders through dividends ($84.3 million) and share repurchases (668,553 shares of our common stock for a total of $207.5 million). We continue to operate with low leverage, with a Net Debt to EBITDA ratio of 2.0 as of December 31, 2022.

The last three years have been characterized by unprecedented factors, including the impact of the COVID-19 pandemic, worldwide supply chain disruptions, inflation, and war. Accordingly, we believe that it is useful to compare our 2022 results to 2019, the last full year before these factors. Petroleum additives sales in 2022 were $578.4 million higher than in 2019, an increase of 26%. Petroleum additives operating profit in 2022 was $19.0 million higher, an increase of 5% over 2019, and shipments in 2022 were 2.8% higher than 2019. Petroleum additives operating margin for 2022 was 13.7% versus 16.5% in 2019.

We are pleased by the performance of our petroleum additives business in 2022 and the work done by our team to navigate through the many challenges of the past three years. While our efforts to resolve supply chain issues to better meet our customers' growing needs have shown improvement, we are still challenged by the inflationary environment and rising operating costs that we expect to continue into 2023. Margin recovery and cost control will remain priorities throughout 2023.

I want to thank our dedicated employees for their commitment to our business and to serving our customers. 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. The Company believes that even though these items are not required by or presented in accordance with United States generally accepted accounting principles (GAAP), these additional measures enhance understanding of the Company's performance and period to period comparability. The Company believes that these items should not be considered an alternative to our results determined under GAAP.
