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 June 30, 2023 and December 31, 2022, and our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the second quarter and six months ended June 30, 2023 and June 30, 2022, and our cash flows for the six months ended June 30, 2023 and June 30, 2022. 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, 2022 (2022 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the six month period ended June 30, 2023 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023. The December 31, 2022 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.
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 the arrangement between our vendor 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 June 30, 2023, the amount of confirmed invoices under the supplier finance program was not material.
2.    Net Sales
Our revenues are primarily derived from the manufacture and sale of petroleum additives products. We sell petroleum additives products across the world to customers located in the North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and EMEAI (Europe/Middle East/Africa/India) regions. Our customers primarily consist of global, national, and independent oil companies. Our contracts generally include one performance obligation, which is providing petroleum additives products. The performance obligation is satisfied at a point in time when products are shipped, delivered, or consumed by the customer, depending on the underlying contracts.
In limited cases, we collect funds in advance of shipping product to our customers and recognizing the related revenue. These prepayments from customers are recorded as a contract liability to our customer until we ship the product and recognize the revenue. Some of our contracts include variable consideration in the form of rebates or business development funds. We regularly review both rebates and business development funds and make adjustments to estimated amounts when necessary, recognizing the full amount of any adjustment in the period identified.

The following table provides information on our net sales by geographic area. Information on net sales by segment is presented in Note 3.

5.    Earnings Per Share
We had 34,448 shares of nonvested restricted stock at June 30, 2023 and 33,230 shares of nonvested restricted stock at June 30, 2022 that were excluded from the calculation of diluted earnings per share. The nonvested restricted stock is considered a participating security since the restricted stock contains nonforfeitable rights to dividends. As such, we use the two-class method to compute basic and diluted earnings per share for all periods presented since this method yields the most dilutive result. The following table illustrates the earnings allocation method utilized in the calculation of basic and diluted earnings per share.

Overview
When comparing the results of the petroleum additives segment for the first six months of 2023 with the first six months of 2022, net sales were substantially unchanged, but included significantly higher selling prices, offset by decreases in product shipments and an unfavorable foreign currency impact. Petroleum additives operating profit was 48.3% higher when comparing the first six months of 2023 with the first six months of 2022, reflecting the higher selling prices that favorably impacted net sales, partially offset by lower product shipments, as well as higher operating costs and raw material costs. Shipments have been lower than our expectations over the last few quarters, as we continue to experience the effects of customer destocking and global economic weakness.
We continue to operate in a general inflationary environment. While we have experienced some improvement in the supply chain disruptions which have impacted the petrochemicals industry over the past several years, we expect to continue to be challenged by high costs during 2023. Despite the challenging economic environment, our financial position remains strong. We have sufficient access to capital, if needed, and do not anticipate any issues with meeting the covenants for all our debt agreements for the foreseeable future.
Our operations generate cash that is in excess of the needs of the business. We continue to invest in and manage our business for the long-term with the goal of helping our customers succeed in their marketplaces. Our investments continue to be in organizational talent, technology development and processes, and global infrastructure.
The chemical industry and our products are essential for transportation of people, goods and services. Our business continuity planning process focuses our efforts on managing through this challenging time and helping our customers do the same.

Results of Operations
Net Sales
Consolidated net sales for the second quarter of 2023 totaled $685.1 million, representing a decrease of $38.5 million, or 5.3%, from the second quarter of 2022. Consolidated net sales for the first six months of both 2023 and 2022 totaled $1.4 billion. The following table shows net sales by segment and product line.

Petroleum Additives Segment
The regions in which we operate include North America, Latin America, Asia Pacific, and the EMEAI region. While there is some fluctuation, the percentage of net sales generated by region remained fairly consistent when comparing the first six months of 2023 with the same period in 2022, as well as with the full year 2022.
Petroleum additives net sales for the second quarter of 2023 were $684.0 million compared to $721.0 million for the second quarter of 2022, a decrease of 5.1%. The decrease for the second quarter comparison was across all regions with Asia Pacific representing about 60%, North America about 20%, Latin America about 15%, and the remainder of the decrease from EMEAI.
Petroleum additives net sales for the first six months of 2023, as well as the first six months of 2022, were $1.4 billion. While petroleum additives net sales were substantially unchanged between the two six months periods, the North America and EMEAI regions reported significant increases for the first six months of 2023 compared to the first six months of 2022, but these increases were substantially offset by similar decreases in the Asia Pacific and Latin America regions.
The following table details the approximate components of the changes in petroleum additives net sales between the second quarter and first six months of 2023 and 2022.

Period ended June 30, 2023$684.0 $1,384.0 
When comparing the second quarter of 2023 and 2022, the decrease in petroleum additives net sales was primarily due to lower lubricant additives shipments, as well as smaller impacts from lower fuel additives shipments and an unfavorable foreign currency impact. These factors were partially offset by increased selling prices in the second quarter comparison. When comparing petroleum additives net sales for the first six months of 2023 and 2022, both lubricant additives and fuel additives shipments were lower, along with an unfavorable foreign currency impact, but all were offset by higher selling prices. Comparing the second quarter of 2023 and 2022, the United States Dollar strengthened against all of the major currencies in which we transact, except for the Euro, resulting in the unfavorable impact to net sales for the comparative periods. The United States Dollar strengthened against all of the major currencies in which we transact for the six months comparison of 2023 with 2022. The unfavorable impact for both the second quarter and six months comparison was predominantly from the Chinese Renminbi, Indian Rupee, and Japanese Yen, while the Euro also unfavorably impacted the six months comparison.
On a worldwide basis, the volume of product shipments for petroleum additives decreased 16.7% when comparing the two second quarter periods and 16.1% when comparing the first six months of 2023 and 2022. Petroleum additives shipments for the second quarter comparison reflected decreases in both lubricant additives and fuel additives with all regions contributing to the decrease in lubricant additives shipments, while North America was the primary contributor to the decrease in fuel additives

shipments. For the six months comparison, both lubricant additives and fuel additives shipments were lower in 2023 than in 2022. The decrease in lubricant additives shipments when comparing the first six months of 2023 with the same period of 2022 was across all regions with around 30% of the decrease in each of the North America, EMEAI, and Asia Pacific regions and the remaining decrease in the Latin America region. The six months comparison for fuel additives shipments reflected decreases in all regions with about 60% of the decrease in North America, 20% in Latin America, and the remainder about evenly split between Asia Pacific and EMEAI.

Segment Operating Profit
NewMarket evaluates the performance of the petroleum additives business based on segment operating profit. NewMarket Services Corporation expenses are charged to NewMarket and each subsidiary pursuant to services agreements between the companies. Depreciation on segment property, plant, and equipment, as well as amortization of segment intangible assets and lease right-of-use assets, is included in segment operating profit.
The following table reports segment operating profit for the second quarter and six months ended June 30, 2023 and June 30, 2022.

Petroleum Additives Segment
Petroleum additives segment gross profit increased $9.8 million and operating profit increased $40.9 million when comparing the second quarter of 2023 to the second quarter of 2022. For the first six months of 2023 compared to the first six months of 2022, petroleum additives segment gross profit increased $46.0 million and operating profit increased $86.1 million.
The following table presents petroleum additives cost of goods sold as a percentage of net sales and the operating profit margin.

Cost of goods sold as a percentage of net sales71.3 %78.2 %71.5 %77.4 %
Operating profit margin19.3 %12.7 %19.1 %12.9 %
For the rolling four quarters ended June 30, 2023, the operating profit margin for petroleum additives was 16.8%, which is within our historical range of operating profit margin. While operating margins will fluctuate from quarter to quarter due to multiple factors, we believe the fundamentals of our business and industry as a whole are unchanged.
When comparing both the second quarter and first six months of 2023 and 2022, both gross profit and operating profit included the favorable impact of significantly higher selling prices, partially offset by lower shipments and higher operating costs. The comparison for the six months periods also included the impact of higher raw material costs during 2023.
While raw material costs, along with other operating costs, increased throughout 2022, we were able to make adjustments to selling prices, which are reflected in our results for the second quarter and first six months comparisons between 2023 and 2022. We have experienced some stabilization of raw material costs during 2023, but nonetheless remain challenged by the ongoing inflationary environment impacting our operations. Cost control and margin management remain high priorities for us.
Petroleum additives selling, general, and administrative expenses (SG&A) for the second quarter of 2023 were $0.6 million lower than the second quarter of 2022. SG&A expenses for the first six months of 2023 were $1.0 million higher than the first six months of 2022. SG&A as a percentage of net sales was 4.4% for the second quarter of 2023, 4.2% for the second quarter of 2022, and 4.5% for both the first six months of 2023 and 2022. Our SG&A costs are primarily personnel-related and include salaries, benefits, and other costs associated with our workforce, including travel-related expenses. While personnel-related costs fluctuate from period to period, there were no significant changes in the drivers of these costs when comparing the periods.

Our investment in petroleum additives research, development, and testing (R&D) decreased approximately $1.4 million when comparing the second quarter periods of 2023 and 2022 and $4.5 million when comparing the first six months periods of 2023 and 2022. As a percentage of net sales, R&D was 5.0% for the second quarter of 2023, 4.9% for the second quarter of 2022, 4.9% for the first six months of 2023, and 5.2% for the first six months of 2022. Our R&D investments reflect our efforts to support the development of solutions that meet our customers' needs, meet new and evolving standards, and support our expansion into new product areas. Our approach to R&D investments, as it is with SG&A, is one of purposeful spending on programs to support our current product base and to ensure that we develop products to support our customers' programs in the future. R&D investments include personnel-related costs, as well as costs for internal and external testing of our products.

The following discussion references certain captions on the Consolidated Statements of Income.

Interest and Financing Expenses, Net
Interest and financing expenses were $10.3 million for the second quarter of 2023, $7.1 million for the second quarter of 2022, $21.0 million for the first six months of 2023, and $16.5 million for the first six months of 2022.
The increase for both the second quarter and six months comparisons resulted primarily from a higher average interest rate. Average debt was also higher for the second quarter comparison, while the six months comparison reflected slightly lower average debt. Both comparison periods included a favorable impact from lower amortization and fees, as well as higher capitalized interest.

Other Income (Expense), Net
Other income (expense), net was income of $10.7 million for the second quarter of 2023, $9.1 million for the second quarter of 2022, $21.6 million for the first six months of 2023, and $16.3 million for the first six months of 2022. The amounts for both the 2023 and 2022 second quarter and six months periods primarily reflect the components of net periodic benefit cost (income), except for service cost, from defined benefit pension and postretirement plans. See Note 4 for further information on total periodic benefit cost (income). The first six months of 2022 also included a loss on marketable securities of $3.0 million.

Income Tax Expense
Income tax expense was $25.1 million for the second quarter of 2023 and $19.1 million for the second quarter of 2022. The effective tax rate was 20.1% for the second quarter of 2023 and 22.4% for the second quarter of 2022. Income tax expense increased $8.8 million due to higher income before income tax expense and decreased $2.8 million due to the lower effective tax rate.
Income tax expense was $52.7 million for the first six months of 2023 and $33.3 million for the first six months of 2022. The effective tax rate was 21.1% for the first six months of 2023 and 20.9% for the first six months of 2022. Income tax expense increased $19.0 million due to higher income before income tax expense with the remaining $0.4 million of the difference caused by the higher effective tax rate.
The decrease in the effective tax rate for the second quarter of 2023 as compared to the second quarter of 2022 was primarily caused by a tax benefit applicable to prior years. The slight increase in the effective tax rate for the six months comparison was primarily the result of an increase in the U.S. tax on foreign earnings and a reduction in the foreign-derived intangible tax benefit, which was partially offset by a tax benefit applicable to prior years.
On October 8, 2021, almost all members of the Organisation for Economic Co-operation and Development (“OECD”) reached an agreement on a two-pillar approach to international tax reform, including the establishment of a 15% global minimum tax for large multinational entities. Several jurisdictions in which we operate have adopted or are in the process of adopting this global minimum tax, with planned effective dates in 2024 or 2025. We are continuing to monitor the legislation in these jurisdictions and any potential impact to our effective tax rate and related income tax liabilities in future years.

Cash Flows, Financial Condition, and Liquidity
Cash and cash equivalents at June 30, 2023 were $130.9 million, an increase of $62.2 million since December 31, 2022.
Cash and cash equivalents held by our foreign subsidiaries amounted to $127.5 million at June 30, 2023 and $65.3 million at December 31, 2022. Periodically, we repatriate cash from our foreign subsidiaries to the United States through intercompany dividends and loans. We do not anticipate significant tax consequences from future distributions of foreign earnings.
A portion of our foreign cash balances is associated with earnings that we have asserted are indefinitely reinvested. We plan to use these indefinitely reinvested earnings to support growth outside of the United States through funding of operating expenses, research and development expenses, capital expenditures, and other cash needs of our foreign subsidiaries.

Table of Contents    

We expect that cash from operations, together with borrowing available under our revolving credit facility, will continue to be sufficient to cover our operating needs and planned capital expenditures for both a short-term and long-term horizon.
Cash Flows – Operating Activities
Cash provided from operating activities for the first six months of 2023 were $262.4 million, including $52.5 million reflecting lower working capital requirements. The $52.5 million excluded an unfavorable foreign currency impact to the components of working capital on the balance sheet.
The most significant changes in working capital included decreases in trade and other accounts receivable, inventories, accounts payable, and accrued expenses. The decrease in trade and other accounts receivable primarily represents the refund of value added taxes at some of our foreign subsidiaries. The decrease in inventories reflects our planned destocking in response to lower demand and destocking by our customers. The decrease in accounts payable is primarily the result of destocking and lower production levels. The change in accrued expenses reflects normal rebate payments to customers.
Including cash and cash equivalents, as well as the impact of changes in foreign currency exchange rates on the balance sheet, we had total working capital of $791.1 million at June 30, 2023 and $768.2 million at December 31, 2022. The current ratio was 3.27 at June 30, 2023 and 2.81 at December 31, 2022.
Cash Flows – Investing Activities
Cash used in investing activities totaled $26.0 million during the first six months of 2023 for capital expenditures. We expect that our total capital spending during 2023 will be in the $50 million to $60 million range and will include several improvements to our manufacturing and R&D infrastructure around the world. We expect to continue to finance capital spending through cash on hand and cash provided from operations, together with borrowing available under our revolving credit facility.
Cash Flows – Financing Activities
Cash used in financing activities during the first six months of 2023 amounted to $175.7 million. These cash flows included net payments of $88.0 million on the revolving credit facility, $42.9 million for repurchases of 119,075 shares of our common stock, and cash dividends of $41.9 million.
Debt
Our long-term debt was $916.2 million at June 30, 2023 compared to $1.0 billion at December 31, 2022.
See Note 8 for additional information on the 2.70% senior notes, 3.78% senior notes, and revolving credit facility, including the unused portion of our revolving credit facility.
All of our senior notes and the revolving credit facility contain covenants, representations, and events of default that management considers typical of credit arrangements of this nature. The covenants under the 3.78% senior notes include negative covenants, certain financial covenants, and events of default which are substantially similar to the covenants and events of default in our revolving credit facility.
The revolving credit facility contains financial covenants that require NewMarket to maintain a consolidated Leverage Ratio (as defined in the agreement) of no more than 3.75 to 1.00, except during an Increased Leverage Period (as defined in the agreement) at the end of each quarter. At June 30, 2023, the Leverage Ratio was 1.70 under the revolving credit facility.
At June 30, 2023, we were in compliance with all covenants under the 3.78% senior notes, 2.70% senior notes, and revolving credit facility.
As a percentage of total capitalization (total long-term debt and shareholders’ equity), our total long-term debt decreased from 56.8% at December 31, 2022 to 50.6% at June 30, 2023. The change resulted primarily from the decrease in outstanding revolving credit facility borrowings, along with the increase in shareholders' equity. The increase in shareholders’ equity primarily reflects our earnings and the impact of foreign currency translation adjustments, partially offset by dividend payments and the repurchases of our common stock. Generally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Outlook
Our stated goal is to provide a 10% compounded return per year for our shareholders over any five-year period (defined by earnings per share growth plus dividend yield), although we may not necessarily achieve a 10% return each year. We continue to have confidence in our customer-focused strategy and approach to the market. 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 of our stakeholders over the long term.
We expect our petroleum additives segment to experience impacts to its operating performance during 2023 due to the uncertain economic environment in which we operate, as we continue to see challenges with inflationary trends impacting our operating costs and raw material prices. As a result, we will continue to focus on cost control and operating profit margin recovery throughout the year. We expect over the long-term that the petroleum additives market will grow annually in the 1% to 2% range. We plan to exceed that growth rate.
Over the past several years we have made significant investments in our business as the industry fundamentals remain positive. These investments have been and will continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability and geographic expansion. We intend to utilize these investments to improve our ability to deliver the solutions that our customers value, expand our global reach, and enhance our operating results. We will continue to invest in our capabilities to provide even better value, service, technology, and customer solutions.
Our business generates significant amounts of cash beyond its operational needs. We regularly review our many internal opportunities to utilize excess cash from technological, geographic, production capability, and product line perspectives. We believe our capital spending is creating the capability we need to grow and support our customers worldwide, and our research and development investments are positioning us well to provide added value to our customers. Our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that this industry segment will provide the greatest opportunity for solid returns on our investments while minimizing risk. We remain focused on this strategy and will evaluate any future opportunities. We will continue to evaluate all alternative uses of cash to enhance shareholder value, including stock repurchases and dividends.
