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, 20232024 and December 31, 2022, and2023, our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the three months ended March 31, 20232024 and March 31, 2022,2023, and our cash flows for the three months ended March 31, 20232024 and March 31, 2022.2023. 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, 2022 (20222023 (2023 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the three month period ended March 31, 20232024 are not necessarily indicative of the results to be expected for the full year ending December 31, 2023.2024. The December 31, 20222023 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 theany arrangement between our vendorvendors 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.
2.    Acquisition of Business
On January 16, 2024, we completed the acquisition of all issued and outstanding ownership units of AMPAC Intermediate Holdings, LLC, the ultimate parent company of American Pacific Corporation (AMPAC), for approximately $700 million. Based in Cedar City, Utah, AMPAC has one operating facility from which it manufactures and sells critical specialty materials primarily used in solid rocket motors for space launch and military defense applications. AMPAC is qualified on many NASA and Department of Defense programs and has been serving space launch and national defense programs for more than 60 years. The acquisition of AMPAC expands our presence in mission-critical, resilient sectors. It was funded by cash on hand and borrowings under our then existing revolving credit facility. The purchase consideration is subject to a customary post-closing adjustment for working capital, which is expected to be finalized during the second quarter of 2024.
The preliminary fair values of the assets acquired and the liabilities assumed in the AMPAC acquisition are as follows (in millions):
Cash and cash equivalents$16 
Trade and other accounts receivable, net
Inventories28 
Prepaid expenses and other current assets
Property, plant, and equipment, net111

Customer base$272 17.5
Formulas and technology60 8
Trademarks and trade names30 15
Water rights30 indefinite
$392 
As part of the acquisition, we recorded $258 million of goodwill. The goodwill recognized is attributable to increased access to mission-critical, resilient sectors with a role in global safety, security, and space exploration, as well as the value of the skilled assembled workforce of AMPAC. All of the goodwill recognized is part of the specialty materials segment, and none of the goodwill is deductible for income tax purposes.
The allocation of the purchase price of AMPAC to the tangible and intangible assets acquired and liabilities assumed was developed using preliminary estimates of fair value and based on information currently available. We are continuing to finalize the valuation of certain assets and liabilities and expect to complete our valuations within one year of the date of acquisition. Acquisition-related charges of $1 million consisted primarily of legal and professional fees and are included in selling, general, and administrative expenses in our Consolidated Statements of Income.
We are accounting for this acquisition using the acquisition method of accounting for business combinations under the provisions of Financial Accounting Standards Board (FASB) Accounting Standard Codification (ASC) Topic 805, Business Combinations (ASC 805) and have included the results of operations of the acquired business in our Consolidated Statement of Income from the date of acquisition, as well as in the specialty materials segment in Note 4. These results include a charge related to the sale of finished goods inventory acquired, which was recorded at fair market value on the acquisition date and sold to customers from the date of acquisition through March 31, 2024. The following table presents the financial results for AMPAC from the date of acquisition through March 31, 2024.

The following table presents our estimated unaudited pro forma consolidated results for the three months ended March 31, 2024 and March 31, 2023, assuming the acquisition of AMPAC had occurred on January 1, 2023. The unaudited pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been realized if the acquisition had been completed at the beginning of 2023, nor is it indicative of expected results for any future period. In addition, no effect is given to any future synergistic benefits that could result from the integration of AMPAC into the NewMarket companies.
Unaudited pro forma information for the three months ended March 31, 2024 and March 31, 2023 include adjustments to depreciation and amortization based upon the fair value allocation of the purchase price to AMPAC's tangible and intangible assets acquired and liabilities assumed as though the acquisition had occurred on January 1, 2023, as well as adjustments for debt-related costs and management fees. The acquisition-related costs and the charge related to the fair value adjustment to acquisition-date inventory were recognized in actual results during the three months ended March 31, 2024, but for the presentation below, these costs are excluded from 2024 unaudited pro forma income before income taxes and are instead reflected in 2023 pro forma income before income taxes as though they were incurred during the three months ended March 31, 2023.

3.    Net Sales
Our revenues are primarilypredominantly 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 petroleum additives customers primarily consist of global, national, and independent oil companies. Our petroleum additives 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.
Additionally, we have revenue from the manufacture and sale of critical specialty materials products used primarily in solid rocket motors for space launch and military defense applications. The sale of specialty materials products is predominantly to customers located in the United States, with limited amounts to customers in other countries. Our specialty materials customers are primarily contractors or subcontractors of the U.S. government. Specialty materials contracts generally include one performance obligation, which is typically satisfied at a point in time when the products are shipped from the plant site.
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, tiered pricing, and/or business development funds. We regularly review both rebates and business development fundsthese and make adjustments to estimated amounts when necessary, recognizing the full amount of any adjustment in the period identified.

5.6.    Earnings Per Share
We had 34,678 shares of nonvested restricted stock at March 31, 2024 and 34,579 shares of nonvested restricted stock at March 31, 2023 and 34,349 shares of nonvested restricted stock at March 31, 2022 that were excluded from the calculation of diluted earnings per share, as their effect on earnings per share would be anti-dilutive.
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 three months of 20232024 with the first three months of 2022,2023, net sales increased 6.0%were 3.2% lower resulting primarily due to significantly higherfrom lower selling prices, which were partially offset by decreasesan increase in product shipments and an unfavorable foreign currency impact.of 4.7%. Petroleum additives operating profit was 51.9%14.3% higher when comparing the first2024 and 2023 three months of 2023 with the first three months of 2022,periods, primarily reflecting the higher selling prices that favorably impacted net sales,favorable impact of lower raw material and operating costs, partially offset by significantly higher raw material costs,the lower selling prices and product mix.
We completed the acquisition of AMPAC for approximately $700 million on January 16, 2024. See Note 2 for further information on the acquisition. The operations of AMPAC since the date of acquisition are reflected in the specialty materials segment in the Results of Operations section below.
On January 22, 2024, we entered into a new $900 million revolving credit facility, as well as higher operating and conversion costs and lower product shipments. Shipments have been lower thana $250 million unsecured term loan.

For the rolling four quarters ended March 31, 2023,2024, the operating profit margin for petroleum additives was 15.2%.
When comparing the first three months20.0%, which is within our historical range of 2023 and 2022, both gross profit and operating profit included the favorable impact of significantly higher selling prices. The favorable impact from higher selling prices was partially offset by significantly higher raw material costs, as well as higher operating and conversion costs and lower product shipments.
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 first three months comparisons between 2023 and 2022. We have experienced some stabilization of raw material costs during the first quarter of 2023, but nonetheless remain challenged by the ongoing inflationary environment impacting raw material and other operating costs, along with a decrease in demand on a global basis.
In this uncertain economic environment of increased costs and lower demand, operating profit margins remain a priority for us. The operating profit margin of 15.2% for the rolling four quarters ended March 31, 2023 is at the lower end of the range of our long-term expectations. As a result, we intend to continue to focus on cost control and margin recovery throughout this year.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 the first three months of 2024 and 2023, the increase in both gross profit and operating profit primarily included the favorable impact of lower raw material and operating costs, partially offset by lower selling prices and product mix. We remain challenged by the ongoing inflationary environment impacting us. Cost control and margin management remain high priorities for us.
Petroleum additives selling, general, and administrative expenses (SG&A) for the first three months of 20232024 were $1.6$0.4 million higherlower than the first three months of 2022.2023. SG&A as a percentage of net sales was 4.7%4.8% for both the first three months of 20232024, and 2022.4.7% for the first three months of 2023. 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 $3.2$2.0 million when comparing the first three months periods of 20232024 and 2022.2023. As a percentage of net sales, R&D was 4.6% for the first three months of 2024 and 4.7% for the first three months of 2023 and 5.5% for the first three months of 2022.2023. 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.
Specialty Materials Segment
The specialty materials segment reported an operating loss of $5.0 million for the period from the AMPAC acquisition date of January 16, 2024 to March 31, 2024. The loss is primarily due to the sale of AMPAC finished goods inventory that we

The amounts for both the 2024 and 2023 and 2022three 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 45 for further information on total periodic benefit cost (income). The first three months of 2022 also included a loss on marketable securities of $3.0 million.

Income Tax Expense
Income tax expense was $30.0 million for the first three months of 2024 and $27.6 million for the first three months of 2023 and $14.2 million2023. The effective tax rate was 21.8% for the first three months of 2022. The effective tax rate was2024 and 22.0% for the first three months of 2023 and 19.3% for the first three months of 2022.2023. Income tax expense increased $10.0$2.8 million due to higher income before income tax expense, with the remaining $3.4which was partially offset by a $0.4 million of the differencedecrease caused by the higherlower effective tax rate.
The increaseOn 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 effective dates in 2024 or 2025. We are continuing to monitor the legislation in these jurisdictions and have recognized an immaterial impact to our effective tax rate and income tax liabilities related to the enactment of these rules for the first three months comparison was primarily the result of an increase in the U.S. tax on foreign earnings and a decreased benefit of the research and development tax credit.2024.

Cash Flows, Financial Condition, and Liquidity
Cash and cash equivalents at March 31, 20232024 were $70.1$117.1 million, an increase of $1.4$5.1 million since December 31, 2022.2023.

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.
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 andincluding planned capital expenditures for both a short-term and long-term horizon.capital expenditures.

Excluding the impact of AMPAC working capital, when comparing the March 31, 2024 balances with those at December 31, 2023, the most significant changes in working capital included decreasesincreases in inventories,trade and other accounts receivable and accounts payable, and a decrease in accrued expenses, as well as anexpenses. The increase in income taxes payable.trade and other accounts receivable primarily reflects higher sales during the first three months of 2024 compared to the fourth quarter of 2023. The decrease in inventories reflects our planned destocking in response to lower demand and destocking by our customers. The decreaseincrease in accounts payable is primarily the result of destockingincreased purchases during the first three months of 2024 and lower production levels.normal invoice payment timing. The change in accrued expenses primarily reflects normal payments related to rebate payments to customers, as well asinterest payments of accrued interest on our long-term debt agreements. The increase in income taxes payable is primarily caused by the timingand personnel payments.

On January 22, 2024, we entered into a new $900 million revolving credit facility, as well as a $250 million unsecured term loan. Concurrently with the entry into the new revolving credit facility, we terminated our former revolving credit facility. See Note 89 for additional information on the 2.70% senior notes, 3.78% senior notes, term loan, and revolving credit facility, including the unused portion of our revolving credit facility.
All of our senior notes, the term loan, 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, as well as the term loan, 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 March 31, 2023,2024, the Leverage Ratio was 1.911.92 under the revolving credit facility.
At March 31, 2023,2024, we were in compliance with all covenants under the 3.78% senior notes, 2.70% senior notes, term loan, and revolving credit facility.

The change resulted primarily from the decreaseincrease in outstanding revolving credit facility and term loan borrowings, along withpartially offset by the increase in shareholders' equity. The increase in shareholders’ equity primarily reflects our earnings, partially offset by dividend payments, the repurchases of our common stock, and the impact of foreign currency translation adjustments.adjustments and dividend payments.

Critical Accounting Policies and Estimates
This Form 10-Q and our 20222023 Annual Report on Form 10-K include discussions of our accounting policies, as well as methods and estimates used in the preparation of our financial statements. We also provided a discussion of Critical Accounting Policies and Estimates in our 20222023 Annual Report on Form 10-K. The following provides an update to the information related to intangibles, net of amortization, and goodwill provided in the Critical Accounting Policies and Estimates section of our 2023 Annual Report on Form 10-K.
ThereWe have beencertain identifiable intangibles amounting to $386.9 million and goodwill amounting to $382.0 million at March 31, 2024 that are discussed in Note 8. Of these identifiable intangibles and goodwill, $124.6 million relate to our petroleum additives business and $644.3 million relate to the specialty materials business. The amortizable identifiable intangibles have remaining lives of up to approximately 17 years. We continue to assess the markets related to the intangibles and goodwill, as well as their specific values and evaluate the intangibles and goodwill for any potential impairment when significant events or circumstances occur that might impair the value of these assets. We have concluded the values are appropriate, as are the amortization periods for the intangibles. However, if conditions were to substantially deteriorate in the petroleum additives or specialty materials markets, it could possibly cause a decrease in the estimated useful lives of the intangible assets or result in a noncash write-off of all or a portion of the intangibles and goodwill carrying amounts. A reduction in the amortization period of the intangibles would have no significant changeseffect on cash flows. We do not anticipate such a change in our critical accounting policies and estimates from those reportedmarket conditions in our 2022 Annual Report on Form 10-K.the near term.

Outlook
Our stated goal is to provide a 10% compounded return per year for our shareholders over any five-yearten-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 20232024 due to the uncertain global economic environment in which we operate, as we continue to see challenges with inflationary trends impacting our operating costs and raw material price volatility.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%up to 2% range.. We plan to exceed that growth rate.rate in our petroleum additives segment.
Over the past several years we have made significant investments in our petroleum additives 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.
We anticipate continued strength in our petroleum additives segment in 2024 and also look forward to the ongoing integration of AMPAC into our business during the year. While we may see substantial variation in quarterly results for AMPAC on an ongoing basis due to the nature of its business, we anticipate full year results to be consistent with our pre-acquisition expectations.
Our business typically 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
While our recent AMPAC acquisition is outside of our core petroleum additives business, we believe it is an excellent opportunity to provide long-term value for our shareholders. Nonetheless, our primary focus in the acquisition area remains on the petroleum additives industry. It is our view that thisthe petroleum additives 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

ITEM 3.     Quantitative and Qualitative Disclosures About Market Risk
At March 31, 2023,2024, there were no material changes in our market risk from the information provided in the 20222023 Annual Report .except for a change in interest rate risk for our variable rate debt.
At December 31, 2023, we had no outstanding variable rate debt under our revolving credit facility. As such, we had no interest rate risk on variable rate debt at December 31, 2023. At March 31, 2024, we had $386 million outstanding under our revolving credit facility and $250 million outstanding under the term loan. Holding all other variables constant at March 31, 2024, if the variable portion of the interest rates hypothetically increased 10%, the effect on our earnings and cash flow would be $3.8 million.
