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, 2021 and December 31, 2020, and our consolidated results of operations, comprehensive income, and changes in shareholders' equity for the second quarter and six months ended June 30, 2021 and June 30, 2020, and our cash flows for the six months ended June 30, 2021 and June 30, 2020. 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, 2020 (2020 Annual Report), as filed with the Securities and Exchange Commission (SEC). The results of operations for the six month period ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year ending December 31, 2021. The December 31, 2020 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.

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, Latin America, Asia Pacific, and Europe/Middle East/Africa/India (EMEAI) 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 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 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 in Note 3.

5.    Earnings Per Share

We had 26,703 shares of nonvested restricted stock at June 30, 2021 and 19,858 shares of nonvested restricted stock at June 30, 2020 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.

6. Marketable Securities

During May 2021, NewMarket invested in both debt and equity marketable securities. The debt securities are designated as trading. The marketable securities are recorded on a settlement date basis at estimated fair value and are classified as current assets in the Consolidated Balance Sheets. Unrealized gains and losses, as well as the investment income attributable to the debt and equity securities, are reported in Other income (expense), net in the Consolidated Statements of Income. The debt securities have a cost basis of $48 million and the equity securities have a cost basis of $331 million at June 30, 2021. The fair value of both the debt and equity securities are shown in the second table below.

The portion of unrealized gains and losses for the period related to both the debt and equity securities still held at the reporting date are as follows:

The indenture governing the 2.70% senior notes includes certain customary covenants that, among other things and subject to certain qualifications and exceptions, limit our ability and the ability of our subsidiaries to:

•grant liens to secure indebtedness;

•engage in sale and lease back transactions;

•merge or consolidate with, or convey, transfer or lease all or substantially all of our assets to a third party.

The outstanding 4.10% senior notes are unsecured, with an aggregate principal amount of $350 million and are registered under the Securities Act of 1933, as amended. The outstanding 3.78% senior notes are unsecured and were issued in a 2017 private placement with The Prudential Insurance Company of America and certain other purchasers.

We were in compliance with all covenants under all issuances of outstanding senior notes as of June 30, 2021 and December 31, 2020.

Revolving Credit Facility - The revolving credit facility has a borrowing capacity of $900 million, a term of five years, and matures on March 5, 2025. The obligations under the revolving credit facility are unsecured and are fully and unconditionally guaranteed by NewMarket. There were no outstanding borrowings under the revolving credit facility at June 30, 2021 or December 31, 2020. As of June 30, 2021 and December 31, 2020 outstanding letters of credit were approximately $2 million resulting in the unused portion of the credit facility amounting to $898 million.

We were in compliance with all covenants under the revolving credit facility as of June 30, 2021 and December 31, 2020.

10.    Commitments and Contingencies

Legal Matters

We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

Environmental

We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party (PRP). While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our consolidated financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $10 million at both June 30, 2021 and December 31, 2020. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets.

Overview

When comparing the results of the petroleum additives segment for the first six months of 2021 with the first six months of 2020, net sales increased 19.2% primarily due to higher lubricant additives product shipments and a favorable foreign currency impact, partially offset by decreased selling prices and lower fuel additives product shipments. Petroleum additives operating profit was 14.7% higher when comparing the first six months of 2021 with the first six months of 2020, reflecting improved product shipments and favorable conversion costs mostly offset by higher raw material costs.

On March 18, 2021, we issued $400 million aggregate principal amount of 2.70% senior notes due 2031. Subsequently, in May 2021, we invested most of the proceeds in marketable securities.

Our operations generate cash that is in excess of the needs of the business. We continue to invest in and manage the business for the long-term with the intent of helping our customers succeed in their marketplaces. Our investments continue to be in organizational talent, technology development and processes, and global infrastructure, consisting of technical centers, production capability, and geographic expansion.

Impact of the COVID-19 Pandemic and Current Economic Environment

While to a lesser extent than during 2020, petroleum additives operating results for the first six months of 2021 include an unfavorable impact from the economic uncertainty resulting from the ongoing effects of the COVID-19 pandemic and the related restrictions on the movement of people, goods and services. The pace and stability of improvement in demand for our products will continue to depend heavily on economic recovery and the rate at which government restrictions are lifted and remain lifted. We will continue to monitor the government restrictions, as well as the status of the vaccination programs that are being implemented globally.

17

All of our locations around the world, including our manufacturing and research and development facilities, have continued to operate safely and without interruption during the pandemic, with only a very few government-ordered, short-term exceptions, and we expect them to continue to do so. Both our raw material supply and the transportation network have experienced some disruptions, but we have managed through these challenges and expect to continue to do so. Our products are being delivered to our customers.

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. Our major capital projects are continuing to progress substantially as planned.

As we operate in the chemical industry, we continue to be focused on protecting the health and safety of our employees and have procedures in place at each of our operating facilities to help ensure their well-being.

The chemical industry and our products are recognized as essential for transportation of goods and services. Our business continuity planning process focuses our efforts on managing through this challenging time and helping our customers do the same. As we are a global company and can leverage the knowledge and experience of our personnel in facilities across the world, we do not expect to experience negative impacts related to short-term travel and border restrictions.

Results of Operations

Net Sales

Consolidated net sales for the second quarter of 2021 totaled $590.7 million, representing an increase of $179.9 million, or 43.8% from the second quarter of 2020. Consolidated net sales for the first six months of 2021 totaled $1.2 billion, representing an increase of $187.1 million, or 19.3%, from the first six months of 2020. The following table shows net sales by segment and product line.

	Second Quarter Ended June 30,				Six Months Ended June 30,

Petroleum Additives Segment

The regions in which we operate include North America (the United States and Canada), Latin America (Mexico, Central America, and South America), Asia Pacific, and the EMEAI region. While there is some fluctuation, the percentage of net sales generated in the regions remained fairly consistent when comparing the first six months of 2021 with the same period in 2020, as well as with the full year in 2020.

Petroleum additives net sales for the second quarter of 2021 were $586.6 million compared to $408.7 million for the second quarter of 2020, an increase of 43.5%. Petroleum additives net sales for the first six months of 2021 were $1.2 billion compared to $966.1 million for the first six months of 2020, an increase of 19.2%. For both the second quarter and six months comparative periods, the increases were across all regions with North America representing around 40% of the increase in both comparative periods. The remaining regions each contributed approximately 20% of the increase in net sales for the second quarter comparison. For the six month comparison, the Asia Pacific region reflected an approximate 35% increase with the EMEAI and Latin America regions reflecting the remaining increases in petroleum additives net sales. While 2021 results continue to include the impact of the COVID-19 pandemic to a lesser extent, the second quarter and six months 2020 periods include a more significant impact from the pandemic.

18

The following table details the approximate components of the increase in petroleum additives net sales between the second quarter and first six months of 2021 and 2020.

(in millions)	Second Quarter		Six Months
Period ended June 30, 2020	$	408.7	$	966.1
Lubricant additives shipments	142.3		183.9
Fuel additives shipments	18.5		(1.4)
Selling prices	7.2		(18.6)
Foreign currency impact, net	9.9		21.5
Period ended June 30, 2021	$	586.6	$	1,151.5

When comparing both the second quarter and the six months periods of 2021 and 2020, petroleum additives shipments accounted for a $160.8 million increase in net sales for the second quarter comparison and a $182.5 million increase in net sales for the six month comparison. Selling prices improved some during the second quarter of 2021, but remained as an unfavorable impact on net sales for the six months comparison. The impact from selling prices was net of a favorable impact from foreign currency exchange rates in both comparative periods. The United States Dollar weakened against most of the major currencies in which we transact when comparing the first six months of 2021 and 2020 resulting in a favorable impact to petroleum additives net sales for both the second quarter and six months comparative periods. The favorable impact was predominantly due to changes in the Euro and Chinese Renminbi exchange rates.

On a worldwide basis, the volume of product shipments for petroleum additives increased 41.1% when comparing the two second quarter periods and 19.1% when comparing the six months of 2021 and 2020. Shipments of lubricant additives increased across all regions in both the second quarter and six months comparisons with most of the increases in the North America region but significant increases across the other regions, as well. Fuel additives shipment volumes increased for the second quarter comparison and were substantially unchanged for the six months comparison. The improvement in the second quarter fuel additives shipments was across all regions, while the six months comparison reflected improved fuel additives product shipments for the North America and Asia Pacific regions with substantially offsetting decreases in the Latin America and EMEAI regions. Similar to the discussion on net sales above, the volume of product shipments in the second quarter of 2020 include the impact from unusually low shipments due to the COVID-19 pandemic.

All Other

The “All other” category includes the operations of the antiknock compounds business and certain contracted manufacturing and services.

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, 2021 and June 30, 2020.

	Second Quarter Ended June 30,				Six Months Ended June 30,
(in millions)	2021		2020		2021		2020
Petroleum additives	$	74.2	$	33.1	$	168.3	$	146.7
All other	$	0.0	$	(0.4)	$	(0.7)	$	0.0

Petroleum Additives Segment

The petroleum additives segment operating profit increased $41.1 million when comparing the second quarter of 2021 to the second quarter of 2020 and $21.6 million when comparing the first six months of 2021 to the first six months of 2020. Both comparative periods included the impact of the same factors that affected gross profit (see discussion below).

The operating profit margin was 12.7% for the second quarter of 2021 as compared to 8.1% for the second quarter of 2020 and was 14.6% for the first six months of 2021 as compared to 15.2% for the first six months of 2020. For the rolling four quarters ended June 30, 2021, the operating profit margin for petroleum additives was 16.2%. Increasing raw material costs during 2021

19

are having a negative impact on our operating profit margins. While we have successfully raised selling prices to allow for the higher raw material costs, the favorable impact of increased selling prices on our operating results lags the impact of higher raw material costs. Operating profit margins remain a priority, and while they will fluctuate from quarter to quarter due to multiple factors, we believe the fundamentals of our business and industry as a whole are unchanged.

Petroleum additives gross profit increased $44.2 million when comparing the two second quarter periods and $26.0 million when comparing the first six months of 2021 and 2020. Cost of goods sold as a percentage of net sales was 76.1% for the second quarter of 2021, down slightly from 76.5% for the second quarter of 2020 and 73.8% for the first six months of 2021, increasing from 71.4% for the first six months of 2020.

When comparing both the second quarters and first six months of 2021 and 2020, the increase in gross profit resulted from improved product shipments, as well as a favorable impact from conversions costs. Selling prices were higher for the second quarter comparison, but remained unfavorable for the six month comparison reflecting some price increases beginning to impact our results during the second quarter of 2021. These factors combined contributed over 100% of the improvement in gross profit for both comparative periods. Raw material costs were significantly unfavorable for both the second quarter and six months comparison.

Petroleum additives selling, general, and administrative expenses (SG&A) for the second quarter of 2021 were $1.2 million higher as compared to the second quarter of 2020, and $1.8 million higher when comparing the first six months of 2021 to the same 2020 period. SG&A as a percentage of net sales was 5.2% for the second quarter of 2021, 7.2% for the second quarter of 2020, 5.4% for the first six months of 2021 and 6.2% for the first six months of 2020. Our SG&A costs are primarily personnel-related and include salaries, benefits, and other costs associated with our workforce, including travel 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) increased $2.0 million when comparing the second quarter of 2021 with the second quarter of 2020 and $2.8 million when comparing the first six months periods of 2021 and 2020. As a percentage of net sales, R&D was 6.1% for the second quarter of 2021, 8.2% for the second quarter of 2020, 6.2% for the first six months of 2021, and 7.2% for the first six months of 2020. 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

Interest and financing expenses were $8.9 million for the second quarter of 2021, $7.0 million for the second quarter of 2020, $15.2 million for the first six months of 2021 and $14.1 million for the first six months of 2020. The increase for both the second quarter and the six months comparison resulted primarily from higher outstanding debt during the 2021 periods, along with higher average interest rate in both 2021 periods. Higher capitalized interest during the 2021 period partially offset the average rate and debt impact.

Other Income (Expense), Net

Other income (expense), net was income of $5.2 million for the second quarter of 2021, $6.5 million for the second quarter of 2020, $12.4 million for the first six months of 2021 and $14.0 million for the first six months of 2020. The amounts for both of the 2021 and 2020 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).

Income Tax Expense

Income tax expense was $15.1 million for the second quarter of 2021 and $4.9 million for the second quarter of 2020. The effective income tax rate was 22.5% for the second quarter of 2021 and 18.0% for the second quarter of 2020. Income tax expense increased $7.2 million due to higher income before income tax expense and $3.0 million resulting from the higher effective income tax rate.

Income tax expense was $34.8 million for the first six months of 2021 and $29.5 million for the first six months of 2020. The effective tax rate was 22.2% for the first six months of 2021 and 21.4% for the first six months of 2020. Income tax expense increased $4.1 million due to higher income before income tax expense. The higher effective income tax rate resulted in a $1.2 million increase in income tax.

20

The increase in the tax rate for both periods is primarily driven by income from our foreign operations.

Cash Flows, Financial Condition, and Liquidity

Cash and cash equivalents at June 30, 2021 were $153.9 million, which was an increase of $28.7 million since December 31, 2020.

Cash and cash equivalents held by our foreign subsidiaries amounted to $117.4 million at June 30, 2021 and $97.3 million at December 31, 2020. 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 and planned capital expenditures for at least the next twelve months.

Cash Flows – Operating Activities

Cash flows provided from operating activities for the first six months of 2021 were $104.1 million, including the use of $59.5 million to fund higher working capital requirements. The $59.5 million used for working capital excluded a favorable foreign currency impact to the components of working capital on the balance sheet.

The most significant changes in working capital included increases in accounts receivable, inventory, and accounts payable. The increase in accounts receivable balances when comparing June 30, 2021 with the end of 2020 was primarily the result of higher sales in certain regions, as well as slightly slower customer payments. The increase in inventory was primarily in response to higher forecasted demand in some regions, as well as increased raw material costs. The increase in accounts payable reflected normal fluctuations across the regions due to timing, increased purchases of raw materials to meet customer demand, and higher raw material costs.

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 $1.1 billion at June 30, 2021 and $585.6 million at December 31, 2020. The current ratio was 3.83 to 1 at June 30, 2021 and 2.87 to 1 at December 31, 2020.

Cash Flows – Investing Activities

Cash used in investing activities totaled $422.2 million during the first six months of 2021 and represented the purchases (net of proceeds from sales and maturities) of marketable securities of $377.8 million and capital expenditures of $44.4 million. We currently expect that our total capital spending during 2021 will be in the $75 million to $85 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 provided from financing activities during the first six months of 2021 amounted to $346.1 million. These cash flows included $395.1 million of proceeds from the issuance of our $400 million 2.70% senior notes. Cash flows from financing activities also included cash dividend payments of $41.5 million.

Debt

Our long-term debt was $990.6 million at June 30, 2021 compared to $598.8 million at December 31, 2020.

On March 18, 2021, we issued $400 million aggregate principal amount of 2.70% senior notes due 2031 at an issue price of 98.763%. We intend to use the net proceeds from the offering for the repayment or redemption of our 4.10% senior notes and for general corporate purposes. We incurred financing costs in 2021 of approximately $4 million related to the 2.70% senior notes, which are being amortized over the term of the notes.

See Note 9 for additional information on the 2.70% senior notes, 4.10% 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.

21

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, 2021, the Leverage Ratio was 2.28 under the revolving credit facility.

At June 30, 2021, we were in compliance with all covenants under the 4.10% senior notes, 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 percentage increased from 44.1% at December 31, 2020 to 53.8% at June 30, 2021. The change in the percentage resulted primarily from the issuance of the 2.70% senior notes, partially offset by the increase in shareholders' equity. The change in shareholders’ equity primarily reflects our earnings offset by dividend payments, and the impact of foreign currency translation adjustments along with the changes in the funded position of our defined benefit plans. Generally, we repay any outstanding long-term debt with cash from operations or refinancing activities.

Critical Accounting Policies and Estimates

This Form 10-Q and our 2020 Annual Report 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 2020 Annual Report.

There have been no significant changes in our critical accounting policies and estimates from those reported in our 2020 Annual Report.

Recent Accounting Pronouncements

There are no new significant recent accounting pronouncements which may materially impact our financial statements.

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 will continue to experience impacts to its operating performance due to the current economic environment. Our global business will see varying effects on demand that will differ by region based on our product portfolio and geographic coverage. The global market should stabilize when government restrictions on the movement of people, goods, and services are lifted, as modern transportation and machinery cannot function without our products. We expect that the petroleum additives market will grow in the 1% to 2% range annually for the foreseeable future. We plan to exceed that growth rate over the long-term.

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.

ITEM 3.     Quantitative and Qualitative Disclosures About Market Risk

At June 30, 2021, there were no material changes in our market risk from the information provided in the 2020 Annual Report except for a change in interest rate risk due to the issuance of the $400 million 2.70% senior notes and the market risk

22

associated with our investment in marketable securities. See Note 9 for information on the 2.70% senior notes and Note 6 for information on the marketable securities.

A hypothetical 100 basis point decrease in interest rates, holding all other variables constant, would have resulted in a change of $59 million in the fair value of our debt at June 30, 2021.

A hypothetical 10% decrease in the trading prices of our marketable securities would have resulted in a $38 million decrease in the fair market value of our marketable securities.

ITEM 4.     Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of internal control over financial reporting to provide reasonable, but not absolute, assurance of the reliability of the financial records and the protection of assets. Under Rule 13a-15(b) of the Securities Exchange Act of 1934 (the Exchange Act), we carried out an evaluation, with the participation of our management, including our principal executive officer and our principal financial officer, of the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) of the Exchange Act, as of the end of the period covered by this report. Based upon that evaluation, our principal executive officer and our principal financial officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level.

There has been no change in our internal control over financial reporting, as such term is defined in Rule 13a-15(f) of the Exchange Act, that occurred during the quarter ended June 30, 2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Revenue from Contract with Customer [Abstract]

Net Sales

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, Latin America, Asia Pacific, and Europe/Middle East/Africa/India (EMEAI) 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 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 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 in Note 3.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings Per Share

We had 26,703 shares of nonvested restricted stock at June 30, 2021 and 19,858 shares of nonvested restricted stock at June 30, 2020 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.

Marketable Securities

Marketable Securities

During May 2021, NewMarket invested in both debt and equity marketable securities. The debt securities are designated as trading. The marketable securities are recorded on a settlement date basis at estimated fair value and are classified as current assets in the Consolidated Balance Sheets. Unrealized gains and losses, as well as the investment income attributable to the debt and equity securities, are reported in Other income (expense), net in the Consolidated Statements of Income. The debt securities have a cost basis of $48 million and the equity securities have a cost basis of $331 million at June 30, 2021. The fair value of both the debt and equity securities are shown in the second table below.

The portion of unrealized gains and losses for the period related to both the debt and equity securities still held at the reporting date are as follows:

The following table provides information on the fair value of the marketable securities, as well as the related level within the fair value hierarchy. The estimated fair value of debt securities is based on reported trades of the debt security adjusted for other observable market data including, but not limited to, benchmark yield curves, market-based quotes of similar assets, and other market-corroborated inputs. The estimated fair value of equity securities is based on actively quoted market prices.

	$	990,551	$	598,848

Senior Notes - On March 18, 2021, we issued $400 million aggregate principal amount of 2.70% senior notes due 2031. The 2.70% senior notes are general unsecured senior obligations and rank equally with our other unsecured senior indebtedness. The offer and sale of the notes were registered under the Securities Act of 1933, as amended. We incurred financing costs in 2021 of approximately $4 million related to the 2.70% senior notes, which are being amortized over the term of the notes.

The indenture governing the 2.70% senior notes includes certain customary covenants that, among other things and subject to certain qualifications and exceptions, limit our ability and the ability of our subsidiaries to:

•grant liens to secure indebtedness;

•engage in sale and lease back transactions;

•merge or consolidate with, or convey, transfer or lease all or substantially all of our assets to a third party.

The outstanding 4.10% senior notes are unsecured, with an aggregate principal amount of $350 million and are registered under the Securities Act of 1933, as amended. The outstanding 3.78% senior notes are unsecured and were issued in a 2017 private placement with The Prudential Insurance Company of America and certain other purchasers.

We were in compliance with all covenants under all issuances of outstanding senior notes as of June 30, 2021 and December 31, 2020.

Revolving Credit Facility - The revolving credit facility has a borrowing capacity of $900 million, a term of five years, and matures on March 5, 2025. The obligations under the revolving credit facility are unsecured and are fully and unconditionally guaranteed by NewMarket. There were no outstanding borrowings under the revolving credit facility at June 30, 2021 or December 31, 2020. As of June 30, 2021 and December 31, 2020 outstanding letters of credit were approximately $2 million resulting in the unused portion of the credit facility amounting to $898 million.

We were in compliance with all covenants under the revolving credit facility as of June 30, 2021 and December 31, 2020.

Legal Matters

We are involved in legal proceedings that are incidental to our business and may include administrative or judicial actions. Some of these legal proceedings involve governmental authorities and relate to environmental matters. For further information, see Environmental below.

While it is not possible to predict or determine with certainty the outcome of any legal proceeding, we believe the outcome of any of these proceedings, or all of them combined, will not result in a material adverse effect on our consolidated results of operations, financial condition, or cash flows.

Environmental

We are involved in environmental proceedings and potential proceedings relating to soil and groundwater contamination, disposal of hazardous waste, and other environmental matters at several of our current or former facilities, or at third-party sites where we have been designated as a potentially responsible party (PRP). While we believe we are currently adequately accrued for known environmental issues, it is possible that unexpected future costs could have a significant impact on our consolidated financial position, results of operations, and cash flows. Our total accruals for environmental remediation, dismantling, and decontamination were approximately $10 million at both June 30, 2021 and December 31, 2020. Of the total accrual, the current portion is included in accrued expenses and the noncurrent portion is included in other noncurrent liabilities on the Condensed Consolidated Balance Sheets.
