Business Segments

We report our business in two distinct segments: petroleum additives, represented by Afton, and TEL, represented by Ethyl. We divide our business this way due to the operational differences between the two business units. The petroleum additives business operates in a market where we actively seek growth opportunities, while TEL is a mature product with declining demand and is marketed primarily through third-party agreements. Financial information concerning our segments is provided in Item 8, “Financial Statements and Supplementary Data.”

Petroleum Additives—Petroleum additives are used in lubricating oils and fuels to enhance their performance in machinery, vehicles, and other equipment. We manufacture chemical components that are selected to perform one or more specific functions and blend those chemicals with other components to form additive packages for use in specified end-user applications. The petroleum additives market is an international marketplace, with customers ranging from oil companies and refineries to original equipment manufacturers (OEMs) and other specialty chemical companies. The petroleum additives segment includes common customers, is served by the same plants, shares common components or building blocks, and is supported with a common sales, as well as research and development, workforce.

We believe our success in the petroleum additives market is largely due to our ability to bring value to our customers. We accomplish this by understanding their needs and applying our technical capabilities, formulation expertise, broadly differentiated product offerings, and global distribution capabilities to meet those needs. We invest significantly in research and development in order to meet our customers’ needs, as well as the rapidly changing environment for new and improved products and services.

We view the petroleum additives marketplace as being comprised of two broad product groupings: lubricant additives and fuel additives. Lubricant additives are highly formulated chemical products that improve the performance, durability, and functionality of mineral oils, synthetic oils, and biodegradable oils, thereby enhancing the performance of machinery and engines. Fuel additives are chemical components and products that improve the refining process and performance of gasoline, diesel, and other fuels, resulting in lower fuel costs, improved vehicle performance, reduced tailpipe or smokestack emissions, or improved power plant efficiency.

Lubricant Additives

Lubricant additives are essential ingredients for lubricating oils. Lubricant additives are used in a wide variety of vehicle and industrial applications, including engine oils, automatic transmission fluids, gear oils, hydraulic oils, turbine oils, and in virtually any other application where metal-to-metal moving parts are utilized. Lubricant additives are organic and synthetic chemical components that enhance wear protection, prevent deposits, and protect against the hostile operating environment of an engine, transmission, axle, hydraulic pump, or industrial machine.

Lubricants are used in nearly every piece of operating machinery from heavy industrial equipment to vehicles. Lubricants provide a layer of insulation and protection between moving mechanical parts. Without this layer of protection, the normal functioning of machinery would not occur. Effective lubricants reduce downtime, prevent accidents, and increase efficiency. Specifically, lubricants serve the following main functions:

Table of Contents

The functionality of lubricants is created through an exact balance between a base fluid and performance enhancing additives. This balance is the goal of effective formulations achieved by experienced research professionals. We offer a full line of lubricant additive products, each of which is composed of component chemicals specially selected to perform desired functions. We manufacture most of the chemical components and blend these components to create products designed to meet industry and customer specifications. Lubricant additive components are generally classified based upon their intended functionality, including:

We are one of the leading global suppliers of specially formulated lubricant additives that combine some or all of the components described above to develop our products. Our products are highly formulated, complex chemical compositions derived from extensive research and testing to ensure all additive components work together to provide the intended results. Our products are engineered to meet specifications prescribed by either the industry generally or a specific customer. Purchasers of lubricant additives tend to be oil companies, distributors, refineries, and compounder/blenders.

Key drivers of demand for lubricant additives include total vehicle miles driven, vehicle production, equipment production, the average age of vehicles on the road, new engine and driveline technologies, and drain/refill intervals.

We view our participation in the lubricant marketplace in three primary areas: engine oil additives, driveline additives, and industrial additives. Our view is not necessarily the same way our competitors view the market.

Engine Oil Additives—The largest submarket within the lubricant additives marketplace is engine oils, which we estimate represents approximately 65% of the overall lubricant additives market volume, but a much lower percentage of the overall market profitability. The engine oils market ultimate customers include consumers, service stations, and OEMs. The extension of drain intervals has generally offset increased demand due to higher vehicle population and more miles driven. The primary functions of engine oil additives are to reduce friction, prevent wear, control formation of sludge and oxidation, and prevent rust. Engine oil additives are typically sold to lubricant manufacturers who combine them with a base oil product to meet internal, industry, and OEM specifications.

Key drivers of the engine oils market are the number of vehicles on the road, drain intervals for engine oils, engine and crankcase size, changes in engine design, and temperature and specification changes driven by the OEMs. Customer and supplier dynamics have created a difficult marketplace for engine oil additives in recent years as the marketplace values engine oil products more like a commodity.

Afton’s goal is to improve the profitability of this product line by developing additives that are specially formulated for the vehicles people drive and the way they drive them. Afton offers additives for oils that we believe protect the modern engine and makes additives that are specially formulated to protect high mileage vehicles. Afton offers products that enhance the performance of mineral, part-synthetic, and fully-synthetic engine oils.

Driveline Additives—The driveline additives submarket is comprised of additives designed for products such as automatic transmission fluids (ATF), gear oils, and tractor fluids. This submarket shares in the 35% of

5

Table of Contents

the market not covered by engine oils but has a much higher profitability than engine oils on a unit basis. ATFs primarily serve as the power transmission and heat transfer medium in the area of the transmission where the torque of the drive shaft is transferred to the gears of the vehicle. Gear additives lubricate gears, bearings, clutches, and bands in the gear-box and are used in vehicles, off-highway, hydraulic, and marine equipment. Other products in this area consist of hydraulic transmission fluids, universal tractor fluids, power steering fluids, shock absorber fluids, gear oils, lubricants for heavy machinery, and vehicle greases. These products must conform to highly prescribed specifications developed by vehicle OEMs for specific models or designs. These additives are generally sold to oil companies and often ultimately sold to vehicle OEMs for new vehicles (factory-fill). End-products are also sold to service dealers for aftermarket servicing (service-fill), as well as retailers and distributors.

Key drivers of the driveline additives marketplace are the number of vehicles manufactured, drain intervals for ATF and gear applications, changes in engine and transmission design and temperatures, and specification changes driven by the OEMs.

Industrial Additives—The industrial additives submarket is comprised of additives designed for products for industrial applications such as hydraulic fluids, grease, industrial gear fluids, industrial specialty applications, and metalworking additives. This submarket also shares in the 35% of the market not covered by engine oils and has a much higher profitability margin than engine oils. These products must conform to industry specifications, OEM requirements and/or application and operating environment demands. Industrial additives are generally sold to oil companies, service dealers for aftermarket servicing, retailers, and distributors.

Key drivers of the industrial additives marketplace are gross domestic product growth and industrial production.

Fuel Additives

Fuel additives are chemical compounds that are used to improve both the oil refining process and the performance of gasoline, diesel, residual, and other fuels. Benefits of fuel additives in the oil refining process include reduced use of crude oil, lower processing costs, and improved fuel storage properties. Fuel performance benefits include ignition improvements, combustion efficiency, reduced emission particulates, fuel economy improvements, and engine cleanliness, as well as protection against deposits in fuel injectors, intake valves, and the combustion chamber. Our fuel additives are extensively tested and designed to meet stringent industry, government, OEM, and individual customer requirements.

Many different types of additives are used in fuels. Their use is generally determined by customer, industry, OEM, and government specifications, and often differs from country to country. The types of fuel additives we offer include:

Table of Contents

We offer a broad line of fuel additives worldwide and sell our products to major fuel marketers and refiners, as well as independent terminals and other fuel blenders.

Key drivers in the fuel additive marketplace include total vehicle miles driven, the introduction of more sophisticated engines, regulations on emissions (both gasoline and diesel), quality of the crude oil slate and performance standards, and marketing programs of major oil companies.

Competition

In the lubricant additives submarket of petroleum additives, we believe that the four top suppliers in 2006 supplied over 80% of the market. These suppliers include Afton, The Lubrizol Corporation, Infineum (a joint venture between ExxonMobil Chemical and Royal Dutch Shell plc), and Oronite (a subsidiary of Chevron). Several other suppliers comprise the remaining market share.

The fuel additives submarket is fragmented and characterized by more competitors. While we participate in many facets of the fuel additives market, our competitors tend to be more narrowly focused. In the gasoline detergent market, we compete mainly against BASF AG, Oronite, and Lubrizol; in the cetane improver market, we compete against Innospec, Groupe SNPE of France, and Exchem EPC Groupe of the U.K.; and in the diesel markets, we compete against Lubrizol, Infineum, BASF, and Innospec.

The competition among the participants in these industries is characterized by the need to provide customers with cost effective, technologically capable products that meet or exceed industry specifications. The need to continually lower cost through formulation technology and cost improvement programs is vital for success in this environment.

Tetraethyl Lead—TEL is a distinct business segment. TEL is used as an octane enhancer in gasoline to improve ignition qualities and operating performance of fuel. Since the 1920s, TEL has been used to prevent “engine knock,” a condition of poor combustion timing causing loss of engine power. In the 1970s, U.S. automobile manufacturers began including emissions control technology in vehicles to comply with the Federal Clean Air Act. When the surface metal of a catalytic converter in emissions control systems was deemed incompatible with lead, unleaded gasoline became the fuel standard in the United States with other countries following. Innospec is now the only manufacturer of TEL worldwide. Through our agreements with Innospec, we receive 32% of the net proceeds from the sale of TEL by Innospec in all regions of the world except North America. In North America, we continue to purchase TEL from Innospec and sell it to selected customers for aviation and racing fuel. Our agreements with Innospec expire in 2010, but contain provisions for extensions thereafter.

As we look forward, we expect a continuing decline in demand for TEL. We do expect that the demand for this product will continue for many years to come, but at a low level of volume and profits.

Raw Materials and Product Supply

We use a variety of raw materials and chemicals in our manufacturing and blending processes and believe the sources of these are adequate for our current operations. The most important raw materials for Afton are base oil, polyisobutylene, maleic anhydride, olefin copolymers, antioxidants, alcohols, and methacrylates. The chemical industry, in general, is experiencing some tightness in the supply of certain commodity materials. We continue to monitor the situation and will adjust our procurement strategies accordingly. Generally, we purchase major raw materials and chemicals under long-term contracts with multi-source suppliers. Certain products, however, are obtained through single-source suppliers.

We have the following long-term supply agreements for raw materials and finished products:

Research, Development, and Testing

Research, development, and testing (R&D) provides the basis for our global petroleum additives technology. We develop products through a combination of chemical synthesis, formulation, engineering design and performance testing. In addition to products, R&D also provides our customers with technical support and product differentiation to assure total customer satisfaction.

We are committed to providing the most advanced products, comprehensive testing programs and superior technical support to our customers and to OEMs worldwide. R&D expenditures, which totaled $70 million in 2006 and $65 million in 2005 and 2004, are expected to grow modestly in 2007 in support of our core technology areas. The efficiency of our R&D spending continues to improve through expansion of internal testing capabilities, implementation of leading-edge data acquisition, control and analysis techniques, and advanced project/portfolio management processes.

Afton continues to develop new technology and products to meet the changing requirements of OEMs and to keep our customers well positioned for the future. A significant portion of our R&D investment is dedicated to the development of the next-generation additive technologies that will be required for future hardware designs, changing use patterns, and the technical differentiation of our customers’ products.

In 2006, we continued the advancement of our global automatic transmission fluid additive line with the commercialization of new highly-durable fluid technologies, both at OEMs and in the service fill arena. New component technology was invented for use in gear additive packages that provides strong anti-wear performance in fuel efficient lubricants. New engine oil component technology and formulations were developed in 2006 which will be commercialized in 2007 in both passenger car and heavy-duty diesel areas. We continued to broaden our product portfolio in the industrial lubricant area with the introduction of several new products and entrance into new markets. Several new products were developed in the fuel additive area, which extend our ability to provide exceptional “keep clean” and “clean up” performance, as well as fuel economy improvement in global vehicle platforms.

Intellectual Property

Our intellectual property, including our patents, licenses, and trademarks, is an important component of our business. We actively protect our inventions, new technologies, and product developments by filing patent applications or maintaining trade secrets. We currently own approximately 1,600 issued United States and foreign patents, with a significant number of additional patents pending. The use of technology covered by several of these patents and trade secrets is licensed to others through a royalty-generating licensing program. In addition, we have acquired the rights under patents and inventions of others through licenses or otherwise. We take care to respect the intellectual property rights of others and we believe our products do not infringe upon those rights. We vigorously participate in patent opposition proceedings around the world, where necessary, to secure a technology base free of infringement. We believe our patent position is strong, aggressively managed, and sufficient for the conduct of our business.

We also have several hundred trademark registrations throughout the world for our marks, including Afton Chemical^®, Ethyl^®, MMT^®, HiTEC^®, and GREENBURN^®, as well as several pending service mark and trademark applications, including NewMarket^SM, TecGARD™, and BioTEC™.

Commitment to Environmental and Safety Excellence

We are committed to continuous improvement and vigilant management of the health and safety of our employees, neighbors, and customers, as well as the stewardship of the environment. One way our companies demonstrate this is through our commitment to the principles of the American Chemistry Council (ACC) Responsible Care^® program. In 2006, the Environmental, Health, Safety and Security Management Systems of both Afton and Ethyl were certified by an independent auditing process as established by the ACC as a requirement of membership. Additionally, Afton’s Sauget, Illinois plant completed certification in the environmental standard ISO 14001. This plant also continues to be an OSHA Star VPP (Voluntary Protection Program) location.

Safety and environmental responsibility is a way of life at NewMarket—enhancing operations, the way we work, and the relationships we maintain with our customers and our communities. Our executive management meetings begin with a review of our environmental and safety performance. We believe we are a leader in the chemical industry with our performance.

Our objective is to establish a culture where our employees understand that good environmental and safety performance is good business and understand that environmental compliance and safety is their personal responsibility.

Our worldwide injury/illness recordable rate (which is the number of injuries per 200,000 hours worked) in 2006 was 0.99. The 2005 rate was 0.72, which was our best year ever. We intend to continue to demonstrate our safety culture with continuous improvement in our safety record. This represents a focused effort by all of our employees. We are extremely proud of our accomplishments in the safety area, especially when compared to safety records in other industries.

As members of the ACC, Afton and Ethyl provide data on twelve metrics used to track environmental, safety, energy use, and product stewardship performance of ACC member companies. These can be viewed at www.responsiblecare-us.com. The information on this website is not, and shall not be deemed to be, a part of this Annual Report on Form 10-K or incorporated by reference in this Annual Report on Form 10-K or any other filings we make with the Securities and Exchange Commission (SEC).

Environmental

We operate under policies that we believe comply with federal, state, local, and foreign requirements regarding the handling, manufacture, and use of materials. One or more regulatory agencies may classify some of these materials as hazardous or toxic. We also believe that we comply in all material respects with laws, regulations, statutes, and ordinances protecting the environment, including those related to the discharge of materials. We expect to continue to comply in all material respects.

We regularly review the status of significant existing or potential environmental issues. We accrue and expense our proportionate share of environmental remediation and monitoring costs in accordance with Statement of Financial Accounting Standards (SFAS) No. 5 and Financial Accounting Standards Board Interpretation No. 14, as clarified by the American Institute of Certified Public Accountants Statement of Position 96-1. As necessary, we adjust our accruals based on current information.

Total gross liabilities accrued at year-end for environmental remediation were $19 million for 2006 and $23 million for 2005. In addition to the accruals for environmental remediation, we also had accruals for dismantling and decommissioning costs of $3 million at December 31, 2006 and $7 million at December 31, 2005. The decrease in these amounts between 2006 and 2005 primarily reflects the dismantling of our TEL facility in Canada. As new technology becomes available, it may be possible to reduce accrued amounts. While we believe that we are fully accrued for known environmental issues, it is possible that unexpected future costs could have a significant financial impact on our financial position and results of operations.

During the third quarter of 2004, we reached a $16 million environmental insurance settlement resulting in the collection of insurance reimbursements. The gain on this settlement amounted to $13 million and is reflected in the Consolidated Statements of Income under the caption “Special item income.” We received $8 million during 2004. We received $4 million in February 2005 and $4 million in February 2006 in accordance with a previously agreed-upon payment schedule.

We spent approximately $16 million in 2006, $13 million in 2005, and $14 million in 2004 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. These environmental operating and clean-up expenses are included in cost of goods sold. In 2007, we expect environmental operating and clean-up costs to be about the same as 2006.

For capital expenditures on pollution prevention and safety projects, we spent $6 million in 2006, $5 million in 2005, and $4 million in 2004.

Our estimate of the effects of complying with governmental pollution prevention and safety regulations is subject to:

We are subject to the federal Superfund law and similar state laws under which we may be designated as a potentially responsible party (PRP). As a PRP, we may be liable for a share of the costs associated with cleaning up hazardous waste sites, such as a landfill to which we may have sent waste.

In de minimis PRP matters and in some minor PRP matters, we generally negotiate a consent decree to pay an apportioned settlement. This relieves us of any further liability as a PRP, except for remote contingencies. Settlement costs for a de minimis participant are typically less than $50,000. Settlement costs for a minor participant are typically less than $300,000.

We are also a PRP at some Superfund sites where our liability may be in excess of de minimis or minor PRP levels. Most Superfund sites where we are a PRP represent environmental issues that are quite mature. The sites have been investigated, and in many cases, the remediation methodology, as well as the proportionate shares of each PRP, has been established. Other sites are not as mature, which makes it more difficult to reasonably estimate our share of the future clean-up or remediation costs. We have previously accrued the estimated expense of the remediation and monitoring of these sites. Generally, remediation and monitoring will go on for an extended period.

During 2000, the Environmental Protection Agency (EPA) named us as a PRP under Superfund law for the clean-up of soil and groundwater contamination at the Sauget Area 2 Site in Sauget, Illinois. Without admitting any fact, responsibility, fault, or liability in connection with this site, we are participating with other PRPs in site investigations and feasibility studies.

The Sauget Area 2 Site PRPs submitted a Remedial Investigation and Feasibility Study (RI/FS) to the EPA in early 2004. We have accrued our estimated proportional share of the expenses for the RI/FS. We also accrued our best estimate of our proportional share of the remediation liability proposed in that submission. The EPA did not accept the RI/FS. Through a series of submissions and meetings, the scope of the RI/FS has changed so that it is now scheduled to be submitted to the EPA in late 2007. The RI/FS work is ongoing, and we believe it is not at a stage where any further conclusion can be drawn as to the remediation liability we may incur. We do not believe there is any additional information available as a basis for revision of the liability that we have established. The amount accrued for this site is not material.

Table of Contents

We also have several other environmental sites where we are in the process of remediation and monitoring. At one of our major sites in the United States, we have substantially completed environmental remediation and will be monitoring the site for an extended period. In addition, during 2004 we began the dismantling and related remediation of some TEL facilities no longer in use at our Canadian plant. That dismantling and remediation is substantially complete and we expect will be fully completed in 2007.

Geographic Areas

We have operations in the United States, Europe, Asia, Latin America, Australia, the Middle East, and Canada. The economies are stable in most of the countries where we operate. In countries with more political or economic uncertainty, we generally minimize our risk of loss by utilizing U.S. Dollar-denominated transactions, letters of credit, and prepaid transactions. We also participate in selective foreign currency forward contracts at certain times. Our foreign customers mainly consist of financially viable government organizations and large companies.

The table below reports net sales and long-lived assets by geographic area. Except for the United States, no country exceeded 10% of net sales during any year. The United States was the only country that exceeded 10% of long-lived assets in any year. We assign revenues to geographic areas based on the location to which the product was shipped. The change in net sales during the three-year period is discussed more fully in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operation.”

Geographic Areas

Net sales to two customers of our petroleum additives segment exceeded 10% of total net sales in 2006, 2005, and 2004. Sales to BP plc and its affiliates (BP) amounted to $127 million (10% of net sales) in 2006, $112 million (10% of total net sales) in 2005, and $99 million (11% of total net sales) in 2004. Sales to Royal Dutch Shell plc and its affiliates (Shell) amounted to $169 million (13% of total net sales) in 2006, $143 million (13% of total net sales) in 2005, and $119 million (13% of total net sales) in 2004. These net sales represent a wide-range of products sold to these two customers in multiple regions of the world.

Recent Developments

In January 2007, Foundry Park I, LLC (Foundry Park I), a wholly-owned subsidiary of NewMarket Development, entered into a Deed of Lease Agreement with MeadWestvaco Corporation (MeadWestvaco) under which MeadWestvaco will lease an office building which will be constructed on approximately three acres of real property which is owned by Foundry Park I. The property is part of a larger office park and mixed-use development known as “Foundry Park.” The office building is designed to include approximately 304,000

rentable square feet. In addition to the office building, MeadWestvaco has the right to parking facilities that are expected to contain approximately 1,050 parking spaces, and the right to use all common areas within the office building and Foundry Park.

Foundry Park I plans to invest between approximately $110 million and $140 million in completing construction of the building. Most of the cost will be financed through construction and permanent indebtedness. Foundry Park I expects construction to require at least two years. The lease, which will cover the entire office building, is a long-term lease with lease payments at competitive market rates.

On November 21, 2006, we commenced a tender offer to purchase any and all $150 million in aggregate principal amount of our outstanding 8.875% senior notes due 2010 and a related solicitation of consents to certain amendments to the indenture governing the 8.875% senior notes designed to remove substantially all of the restrictive covenants and certain events of default that applied to the 8.875% senior notes. As of 5:00 p.m., New York City time, on December 21, 2006, the expiration date for the tender offer, we had accepted tender of 8.875% senior notes from holders of $149,750 million (or 99.83%) in aggregate principal amount of the outstanding 8.875% senior notes. We redeemed the remaining $250,000 in aggregate principal amount of the 8.875% senior notes on February 7, 2007 at a redemption price equal to 105.105% of the principal amount of the redeemed notes, plus accrued and unpaid interest to February 7, 2007.

ITEM 1A.    RISK FACTORS

Our business is subject to many factors that could materially adversely affect our future performance and cause our actual results to differ materially from those expressed or implied by forward-looking statements made in this Annual Report on Form 10-K. Those risk factors are outlined below.

We face intense competition in certain of the product lines and markets in which we compete. We expect that our competitors will develop and introduce new and enhanced products, which could cause a decline in the market acceptance of certain products we manufacture. Our competition may also expand their production capacity, which could decrease market prices for our products and adversely affect our profitability. In addition, as a result of price competition, we may be compelled to reduce the prices for some of our products, which could adversely affect our margins and profitability. Competitive pressures can also result in the loss of major customers. Our inability to compete successfully could have a material adverse effect on our results of operations, financial condition, and cash flows in any given period. In addition, some of our competitors may have greater financial, technological, and other resources than we have. Some of our competitors may also be able to maintain greater operating and financial flexibility

12

Table of Contents

than we are able to maintain. As a result, these competitors may be able to better withstand changes in conditions within our industry, changes in the prices for raw materials, and changes in general economic conditions.

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, maleic anhydride, olefin copolymers, antioxidants, alcohols, and methacrylates. Our profitability is sensitive to changes in the costs of these materials caused by changes in supply, demand or other market conditions, over which we have little or no control. Political and economic conditions in the Middle East and Latin America have caused and may continue to cause the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest, or other incidents may also cause a sudden or sharp increase in the cost of our raw materials. We cannot assure you that we will be able to pass on to our customers any future increases in raw material costs in the form of price increases for our products.

The chemical industry and transportation industry are in a situation where supply and demand are in balance. Any significant disruption in supply could affect our ability to obtain raw materials or transportation systems. This could have a material adverse effect on our operations.

Our principal customers are major multinational oil companies. The oil industry is characterized by concentration of a few large participants as a result of consolidation. Two of our customers individually accounted for more than 10% of our net sales in 2006. Net sales for 2006 to BP amounted to $126 million (10% of total net sales), and net sales to Shell amounted to $169 million (13% of total net sales). The loss of either of these customers, or a material reduction in purchases by either of them, or by any other large or significant customer, could have a material adverse effect on our results of operations, financial condition, and cash flow.

Most of our customers are primarily engaged in the fuel and lubricant industries. This concentration of customers affects our overall risk profile, since our customers will be similarly affected by changes in economic, geopolitical, and industry conditions. Many factors affect the level of our customers’ spending on our products, including, among others, general business conditions, changes in technology, interest rates, gasoline prices, and consumer confidence in future economic conditions. A sudden or protracted downturn in these industries could adversely affect the buying power and purchases by our customers.

Our future business success will depend upon our ability to maintain and enhance our technological capabilities, develop and market products and applications that meet changing customer needs, and successfully anticipate or respond to technological changes on a cost-effective and timely basis. Our industry is characterized by frequent changes in industry performance standards, which affect the amount and timing of our research and development costs and other technology-related costs. As a result, the life cycle of our products is often hard to predict. Further, technological changes in some or all of our customers’ products or processes may make our products obsolete. Any inability to anticipate, respond to,

13

Table of Contents

or utilize changing technologies could have a material adverse effect on our results of operations, financial condition, and cash flow in any given period.

As part of our business growth strategy, we intend to pursue acquisitions and joint venture opportunities. Our ability to implement this component of our growth strategy will be limited by our ability to identify appropriate acquisition or joint venture candidates and our financial resources, including available cash and borrowing capacity. The expense incurred in consummating acquisitions or entering into joint ventures, the time it takes to integrate an acquisition, or our failure to integrate businesses successfully, could result in unanticipated expenses and losses. Furthermore, we may not be able to realize any of the anticipated benefits from acquisitions or joint ventures.

The process of integrating acquired operations into our existing operations may result in unforeseen operating difficulties and may require significant financial resources that would otherwise be available for the ongoing development or expansion of existing operations. Some of the risks associated with the integration of acquisitions include:

Historically, TEL, an octane enhancer in leaded gasoline used to improve ignition qualities and operating performance of fuel, has been a material component of our product line. However, during the 1970s, the implementation of the Federal Clean Air Act led to the use of catalytic converters that are deemed no longer compatible with leaded gasoline, and unleaded gasoline became the fuel standard in the United States with other countries following. As a result, our TEL financial results have declined. The TEL segment represented approximately 2.8% of our 2006 segment operating profit. We do not expect TEL to rebound from this low level of profits.

Results for our TEL segment include the operating profit contribution from marketing agreements between Ethyl or its subsidiaries and subsidiaries of Innospec for the sale of TEL outside of North

14

Table of Contents

America. Innospec is now the only manufacturer of TEL worldwide. Under our marketing agreements with Innospec, we receive 32% of the net proceeds from the sale of TEL by Innospec in all regions of the world, except North America. As a result, our TEL results would be adversely affected if Innospec did not comply with the terms of the marketing agreements.

After the commencement of the arbitration discussed below, Ethyl received three requests for arbitration filed by three subsidiaries of Innospec related to the marketing agreements. Innospec is claiming the right to terminate the agreements. Although the marketing agreements relate only to TEL, Innospec contends that the agreements impose certain duties that were breached by sales and marketing of MMT in Iraq and South Africa by affiliates of Ethyl. Although we believe these claims have no merit, an adverse outcome in the arbitrations could have a material effect on our financial condition or results of operations.

Ethyl filed a request for arbitration against a subsidiary of Innospec related to a supply agreement that requires the Innospec subsidiary to supply Ethyl with TEL for resale by Ethyl in the United States. Ethyl filed this request because it believes that Innospec has violated the supply agreement by attempting to increase the price it charges Ethyl for TEL in the United States in a manner not in accordance with the contract. The difference in prices that Innospec is claiming is approximately $1.7 million for product supplied through September 30, 2006 and would amount to approximately an additional $1 million if the same factors were applied to TEL supplied in the fourth quarter 2006. We are confident in our position and believe we will prevail. Regardless of the outcome, we do not believe the TEL dispute will have a material effect on our financial condition or results of operations. However, with TEL segment operating profit at such a low level, a relatively small increase in cost resulting from this arbitration could be material to TEL segment results.

Several of the products we produce or sell are produced only in one location. We are dependent upon the continued safe operation of those production facilities. Those production facilities are subject to various hazards associated with the manufacture, handling, storage, and transportation of chemical materials and products, including leaks and ruptures, explosions, fires, inclement weather and natural disasters, unscheduled downtime, and environmental hazards. Some of our products involve the manufacture and handling of a variety of reactive, explosive, and flammable materials. Many of these hazards could cause a disruption in the production of our products. We cannot assure you that these facilities will not experience these types of hazards and disruptions in the future or that these incidents will not result in production delays or otherwise have an adverse effect on our results of operations, financial condition or cash flows in any given period.

In 2006, net sales to customers outside North America accounted for approximately 52% of total net sales. We do business in all major regions of the world, some of which do not have stable economies or governments. In particular, we sell and market products in countries experiencing political and economic instability in the Middle East, Asia Pacific, and Latin America. Our international operations are subject to international business risks, including unsettled political conditions, expropriation, import and export restrictions, increases in royalties, exchange controls, national and regional labor strikes, taxes, government royalties, inflationary economies and currency exchange rate fluctuations, and changes in laws and policies governing operations of foreign-based companies (such as restrictions on repatriation of earnings or proceeds from liquidated assets of foreign subsidiaries). The occurrence of any one or a combination of these factors may increase our costs or have other adverse effects on our business.

15

Table of Contents

We conduct our business in the local currency of most of the countries in which we operate. The financial condition and results of operations of our foreign operating subsidiaries are reported in the relevant local currency and then translated to U.S. Dollars at the applicable currency exchange rate for inclusion in our consolidated financial statements. Changes in exchange rates between these foreign currencies and the U.S. Dollar will affect the recorded levels of our assets and liabilities as foreign assets and liabilities are translated into U.S. Dollars for presentation in our financial statements, as well as our net sales, cost of goods sold, and operating margins. The primary foreign currencies in which we have exchange rate fluctuation exposure are the European Union Euro, British Pound Sterling, Japanese Yen, and Canadian Dollar. Exchange rates between these currencies and U.S. Dollars have fluctuated significantly in recent years and may do so in the future.

Protection of our proprietary processes, methods, compounds, and other technologies is important to our business. We depend upon our ability to develop and protect our intellectual property rights to distinguish our products from those of our competitors. Failure to protect our existing intellectual property rights may result in the loss of valuable technologies or having to pay other companies for infringing on their intellectual property rights. We rely on a combination of patent, trade secret, trademark, and copyright law, as well as judicial enforcement, to protect such technologies. We currently own approximately 1,600 issued U.S. and foreign patents, with a significant number of additional patents pending. Some of these patents are licensed to others. In addition, we have acquired the rights under patents and inventions of others through licenses or otherwise. We have developed and may in the future develop technologies with universities or other academic institutions, or with the use of government funding. In such cases, the academic institution or the government may retain certain rights to the developed intellectual property. We also own approximately 500 trademark and service mark registrations throughout the world for our marks, including Afton Chemical^®, Ethyl^®, HiTEC^®, GREENBURN^® and MMT^®, as well as pending trademark and service mark applications, including BioTEC^™, TecGARD^™ and NewMarket^SM. In the event that we are unable to continue using certain of our marks, we may be forced to rebrand our products, which could result in the loss of brand recognition, and could require us to devote resources to advertise and market brands. In particular, the loss of our HiTEC^® mark would have a material adverse effect on our business.

We cannot assure you that the measures taken by us to protect these assets and rights will provide meaningful protection for our trade secrets or proprietary manufacturing expertise or that adequate remedies will be available in the event of an unauthorized use or disclosure of our trade secrets or manufacturing expertise. We cannot assure you that any of our intellectual property rights will not be challenged, invalidated, circumvented, or rendered unenforceable. Furthermore, we cannot assure you that any pending patent application filed by us will result in an issued patent, or if patents are issued to us, that those patents will provide meaningful protection against competitors or against competitive technologies. The failure of our patents or other measures to protect our processes, apparatuses, technology, trade secrets and proprietary manufacturing expertise, methods, and compounds could have an adverse effect on our results of operations, financial condition, and cash flow.

We could face patent infringement claims from our competitors or others alleging that our processes or products infringe on their proprietary technologies. If we are found to be infringing on the proprietary technology of others, we may be liable for damages, and we may be required to change our processes, to redesign our products partially or completely, to pay to use the technology of others or to stop using certain technologies or producing the infringing product entirely. Even if we ultimately prevail in an infringement suit, the existence of the suit could prompt customers to switch to products that are not the subject of infringement suits. We may not prevail in any intellectual property litigation and such litigation may result in significant legal costs or otherwise impede our ability to produce and distribute key products.

16

Table of Contents

We are subject to regulation by local, state, federal, and foreign governmental authorities. In some circumstances, before we may sell certain products, these authorities must approve these products, our manufacturing processes, and facilities. We are also subject to ongoing reviews of our products, manufacturing processes, and facilities by governmental authorities.

In order to obtain regulatory approval of certain new products, we must, among other things, demonstrate to the relevant authority that the product is safe and effective for its intended uses and that we are capable of manufacturing the product in accordance with current regulations. The process of seeking approvals can be costly, time consuming, and subject to unanticipated and significant delays. There can be no assurance that approvals will be granted to us on a timely basis, or at all. Any delay in obtaining, or any failure to obtain or maintain, these approvals would adversely affect our ability to introduce new products and to generate net sales from those products.

New laws and regulations may be introduced in the future that could result in additional compliance costs, seizures, confiscation, recall, or monetary fines, any of which could prevent or inhibit the development, distribution, and sale of our products. If we fail to comply with applicable laws and regulations, we may be subject to civil remedies, including fines, injunctions, and recalls or seizures, any of which could have an adverse effect on our results of operations, financial condition, and cash flow.

Our business and our customers will be subject to significant new regulations under the European Commission’s Registration, Evaluation and Authorization of Chemicals (REACH) regulation. REACH will enter into force on June 1, 2007. It imposes obligations on European Union manufacturers and importers of chemicals and other products into the European Union to compile and file comprehensive reports, including testing data, on each chemical substance, perform chemical safety assessments, and obtain pre-market authorization with respect to certain substances of particularly high concern. The new regulation imposes significant additional burdens on chemical producers and importers, and, to a lesser extent, downstream users of chemical substances and preparations. Our manufacturing presence and sales activities in the European Union will likely require us to incur significant additional compliance costs.

The EPA studied MMT and determined that it does not cause or contribute to the failure of vehicle emission systems. The Canadian government has made similar findings. However, the EPA is requiring additional testing to fill some data gaps, including potential risks to public health, and a change in current determinations could have a material adverse effect on our results of operations. In addition, certain industry groups are urging greater regulation of all metal-based gasoline additives, including MMT. In 2002, the Alliance of Automobile Manufacturers (AAM) issued a fleet test report on MMT based on tests conducted by the AAM, the Association of International Automobile Manufacturers, and the Canadian Vehicle Manufacturers’ Association. The report alleges that MMT significantly raises vehicle emissions, increases fuel emissions, increases fuel consumption, and impairs the proper operation of vehicle emission control systems. In December 2003, the government of Canada released its “Proposed Framework for an Independent Third-Party Review of New Information on the Effects of MMT on Vehicle Emissions.” In its proposal, the Canadian government provided no timetable for the commencement or completion of the review. Substantially all of our customers in Canada have suspended the use of MMT, pending the results of the government of Canada-sponsored independent third-party review. To date, the government of Canada has not initiated the review. We expect that the European Union will also review all metal-based petroleum additives, including MMT, for their impact on pollution abatement technology. Increased government regulation of MMT if it occurs or additional studies evaluating MMT, even if government regulation does not occur, could have a material adverse effect on our sales of that product.

We are involved in numerous administrative and legal proceedings that result from, and are incidental to, the conduct of our business. From time to time, these proceedings involve environmental, product liability, TEL, premises asbestos liability, and other matters. See Item 3, “Legal Proceedings.” We have insurance coverage that we believe would be available to mitigate potential damages in many of these proceedings. However, there is no assurance that our available insurance will cover these claims, that our insurers will not challenge coverage for certain claims, or that final damage awards will not exceed our available insurance coverage. Any of the foregoing could have a material adverse effect on our results of operations, financial condition, and cash flows in any given period.

As a manufacturer and distributor of chemical products, we are generally subject to extensive local, state, federal, and foreign environmental, safety, and health laws and regulations concerning, among other things, emissions to the air, discharges to land and water, the generation, handling, treatment, and disposal of hazardous waste and other materials, and remediation of contaminated soil, surface, and ground water. Our operations entail the risk of violations of those laws and regulations, many of which provide for substantial fines and criminal sanctions for violations. We believe our operations are currently in substantial compliance with these laws and regulations in all material respects. However, we cannot assure you that we have been or will be at all times in compliance with all of these requirements.

In addition, these requirements, and the enforcement or interpretation of these requirements, may become more stringent in the future. Although we cannot predict the ultimate cost of compliance with any such requirements, the costs could be material. Non-compliance could subject us to material liabilities, such as government fines, damages arising from third-party lawsuits, or the suspension and potential cessation of non-compliant operations. We may also be required to make significant site or operational modifications at substantial cost. Future developments could also restrict or eliminate the use of or require us to make modifications to our products, which could have an adverse effect on our results of operations, financial condition, and cash flows in any given period.

At any given time, we are involved in claims, litigation, administrative proceedings, and investigations of various types in a number of jurisdictions involving potential environmental liabilities, including clean-up costs associated with waste disposal sites, natural resource damages, property damage, and personal injury. We cannot assure you that the resolution of these environmental matters will not have an adverse effect on our results of operations, financial condition, and cash flows in any given period.

There may be environmental problems associated with our properties of which we are unaware. Some of our properties contain, or may have contained in the past, on-site facilities or underground tanks for the storage of chemicals, hazardous materials, and waste products that could create a potential for release of hazardous substances or contamination of the environment. The discovery of environmental liabilities attached to our properties could have a material adverse effect on our results of operations, financial condition, and cash flow.

We may also face liability arising from current or future claims alleging personal injury, product liability, property damage due to exposure to chemicals or other hazardous substances, such as premises asbestos, at or from our facilities. We may also face liability for personal injury, product liability, property damage, natural resource damage, or clean-up costs for the alleged migration of contaminants or hazardous substances from our facilities or for future accidents or spills. A significant increase in the number or success of these claims could adversely affect our financial condition, results of operations, and cash flow. For further discussion of some related claims, see Item 1, “Business—Environmental.”

The ultimate costs and timing of environmental liabilities are difficult to predict. Liability under environmental laws relating to contaminated sites can be imposed retroactively and on a joint and several basis. A liable party could be held responsible for all costs at a site, whether currently or formerly owned

18

Table of Contents

or operated regardless of fault, knowledge, timing of the contamination, cause of the contamination, percentage of contribution to the contamination, or the legality of the original disposal. We could incur significant costs, including clean-up costs, natural resource damages, civil or criminal fines and sanctions, and third-party claims, as a result of past or future violations of, or liabilities under, environmental laws.

We are subject to the federal Superfund law and similar state laws under which we may be designated as a PRP. As a PRP, we may be liable for a share of the costs associated with cleaning up hazardous waste sites, such as a landfill to which we may have sent waste.

In de minimis PRP matters and in some minor PRP matters, we generally negotiate a consent decree to pay an apportioned settlement. This relieves us of any further liability as a PRP, except for remote contingencies. Settlement costs for a de minimis participant are less than $50,000. Settlement costs for a minor participant are less than $300,000.

We are also a PRP at Superfund sites where our liability may be in excess of de minimis or minor PRP levels. Most Superfund sites where we are a PRP represent environmental issues that are quite mature. The sites have been investigated, and in many cases, the remediation methodology, as well as the proportionate shares of each PRP have been established. Other sites are not as mature, which makes it more difficult to reasonably estimate our share of future clean-up or remediation costs. Generally, remediation and monitoring will go on for an extended period. As a result, we may incur substantial expenses for all these sites over a number of years, a portion of which may be covered by insurance.

External factors beyond our control, such as customer orders, product shipment dates, and other factors can cause shifts in net sales and income from quarter to quarter. These external factors can magnify the impact of industry cycles. As a result, our income and cash flow may fluctuate significantly on a quarter-to-quarter basis, and your ability to gauge trends in our business may be impaired.

Our senior credit agreement and senior notes contain restrictive covenants. These covenants may constrain our activities and limit our operational and financial flexibility. The failure to comply with these covenants could result in an event of default, which, if not cured or waived, could have a material adverse effect on our business, financial condition, and results of operations.

Our business is subject to hazards common to chemical manufacturing, storage, handling, and transportation, including explosions, fires, inclement weather, natural disasters, mechanical failure, unscheduled downtime, transportation interruptions, remediation, chemical spills, discharges or releases of toxic or hazardous substances or gases, and other risks. These hazards can cause personal injury and loss of life, severe damage to, or destruction of, property and equipment, and environmental contamination. In addition, the occurrence of material operating problems at our facilities due to any of these hazards may diminish our ability to meet our output goals. Accordingly, these hazards and their consequences could have a material adverse effect on our operations as a whole, including our results of operations, and cash flows, both during and after the period of operational difficulties.

Our pension plan asset allocation is predominantly weighted towards equities. Cash contribution requirements to our pension plans are sensitive to changes in our plans’ actual return on assets. Reductions in our plans’ expected return on assets due to poor performance of the equities markets could cause our pension plans to be underfunded and require us to make additional cash contributions.

We maintain property, business interruption, and casualty insurance, but such insurance may not cover all risks associated with the hazards of our business and is subject to limitations, including deductibles and maximum liabilities covered. We may incur losses beyond the limits, or outside the coverage, of our insurance policies, including liabilities for environmental remediation. In the future, we may not be able to obtain coverage at current levels, and our premiums may increase significantly on coverage that we maintain.

Chemical-related assets may be at greater risk of future terrorist attacks than other possible targets in the United States and throughout the world. Federal legislation is under consideration that could impose significant new site security requirements specifically on chemical manufacturing facilities that may increase our overhead expenses. Federal regulations have already been adopted to increase the security of the transportation of hazardous chemicals in the United States.

The occurrence of extraordinary events, including future terrorist attacks and the outbreak or escalation of hostilities, cannot be predicted, and their occurrence can be expected to continue to affect negatively the economy in general, and specifically the markets for our products. The resulting damage from a direct attack on our assets or assets used by us could include loss of life and property damage. In addition, available insurance coverage may not be sufficient to cover all of the damage incurred or, if available, may be prohibitively expensive.

ITEM 1B.    UNRESOLVED STAFF COMMENTS

None.

ITEM 2.    PROPERTIES

Our principal operating properties are shown below. Unless indicated, we own the research, development, and testing facilities and manufacturing properties, which primarily support the petroleum additives business segment.

20

Table of Contents

We own our corporate headquarters located in Richmond, Virginia, and generally lease our regional and sales offices located in a number of areas worldwide.

We own approximately 42 acres of real estate available for development in downtown Richmond, Virginia, adjacent to our principal executive offices. In January 2007, Foundry Park I, a wholly-owned subsidiary of NewMarket Development, entered into a Deed of Lease Agreement with MeadWestvaco under which it will lease an office building which we will construct on approximately three acres.

Production Capacity

We believe our plants and supply agreements are sufficient to meet expected sales levels. Operating rates of the plants vary with product mix and normal sales swings. We believe that our facilities are well maintained and in good operating condition.

ITEM 3.    LEGAL PROCEEDINGS

We are involved in legal proceedings that are incidental to our business and include administrative or judicial actions seeking remediation under environmental laws, such as Superfund. Some of these legal proceedings relate to environmental matters and involve governmental authorities. For further information see “Environmental” in Part I, Item 1.

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 financial condition or results of operations.

Innospec Inc.

On August 16, 2006, Ethyl filed a request for arbitration against a subsidiary of Innospec. This arbitration is related to a long-standing supply agreement that requires the Innospec subsidiary to supply Ethyl with TEL for resale by Ethyl in the United States (the U.S. Supply Agreement). The request was filed pursuant to the rules of the London Court of International Arbitration. Ethyl filed this request because it believes that Innospec has violated the U.S. Supply Agreement by attempting to increase the price it charges Ethyl for TEL in the United States in a manner not in accordance with the contract. As such, we have not recorded an accrual of these costs. The difference in prices that Innospec is claiming is approximately $1.7 million for product supplied through September 30, 2006 and would amount to approximately an additional $1 million if the same factors were applied to TEL supplied in the fourth quarter 2006. We have placed $1.7 million for product supplied through September 30, 2006 in an escrow account pending resolution of the arbitration. We are confident in our position and believe we will prevail. Regardless of the outcome, we do not believe the TEL dispute will have a material effect on our financial condition, results of operations, or cash flows. However, with TEL segment operating profit at such a low level, a relatively small increase in cost may be material to TEL segment results.

After the commencement of the above arbitration, Ethyl received three requests for arbitration filed by three subsidiaries of Innospec. The Innospec requests were filed on October 2, 2006, pursuant to the rules of the London Court of International Arbitration and allegedly pursuant to long-standing marketing and supply agreements between Ethyl or its subsidiaries and subsidiaries of Innospec for the sale of TEL outside of the United States. Innospec is claiming the right to terminate the agreements and is seeking damages. Although these marketing and supply agreements relate only to TEL, Innospec contends that the agreements impose certain duties that were breached by the sales and marketing of MMT in Iraq and South Africa by affiliates of Ethyl. Ethyl will vigorously defend the cases and believes it will ultimately prevail in these arbitrations. Therefore, no accrual has been recorded.

Infineum International Ltd. and Infineum USA L.P.

In December 2005, Afton was sued by a competitor, Infineum International Ltd. and Infineum USA L.P., (Infineum) in federal court in Delaware. The suit alleged patent infringement of one patent in connection with some lubricant additive packages. Infineum and Afton have entered into an agreement to resolve Infineum’s claims against Afton’s products and to effect settlement of the patent infringement suit. The lawsuit has been dismissed.

TEL

Legal proceedings include certain product liability cases. The only product liability cases of potential consequence in which we are involved are TEL-related. In one case, Ethyl was served as a defendant in a case filed in the Circuit Court for Baltimore City, Maryland, in September 1999. The plaintiffs in Smith, et al. v. Lead Industries Association, Inc., et al., alleged personal injuries for seven children from lead exposure arising from lead paint and dust from tailpipe emissions due to leaded gasoline. The court dismissed Ethyl and some other defendants from the case in February 2002 and granted summary judgment to other defendants in November 2002. However, a series of appellate and trial court decisions have the effect that an appeal remains pending against other defendants. It is our current belief that these proceedings will not have a material impact on our consolidated financial condition or result of operations.

Asbestos

Like many other companies, we are also a defendant in personal injury lawsuits involving exposure to asbestos. These cases involve exposure to asbestos in premises owned or operated, or formerly owned or operated, by subsidiaries of NewMarket. We have never manufactured, sold, or distributed products that contain asbestos. Nearly all of these cases are pending in Texas, Louisiana, or Illinois and involve multiple defendants. We maintain an accrual for these proceedings, as well as a receivable for expected insurance recoveries.

During 2005, we entered into an agreement with Travelers Indemnity Company (Travelers) resolving certain long-standing issues regarding our coverage for certain premises asbestos claims. In addition, our agreement with Travelers provides a procedure for allocating defense and indemnity costs with respect to certain future premises asbestos claims. The lawsuit we had previously filed against Travelers in the Southern District of Texas was dismissed. We also settled our outstanding receivable from Albemarle for certain premises asbestos liability obligations.

The accrual for our premises asbestos liability related to currently asserted claims is based on the following assumptions and factors:

22

Table of Contents

Based on the above assumptions, we have provided an undiscounted liability related to premises asbestos claims of $12 million at year-end 2006 and $10 million at year-end 2005. The liabilities related to asbestos claims are included in accrued expenses (current portion) and other noncurrent liabilities on the balance sheet. Certain of these costs are recovered through our insurance coverage and agreement with Albemarle. The receivable for these recoveries related to premises asbestos liabilities was $9 million at December 31, 2006 and $8 million at December 31, 2005. These receivables are included in trade and other accounts receivable for the current portion. The noncurrent portion is included in other assets.

ITEM 4.    SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

There were no issues submitted to a vote of security holders during the fourth quarter of 2006.

ITEM 5.    MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Our common stock, with no par value, has traded on the New York Stock Exchange (NYSE) under the symbol “NEU” since June 21, 2004 when we became the parent holding company of Ethyl and its subsidiaries.

There were 17,289,860 shares of our common stock outstanding as of December 31, 2006. We had 3,627 shareholders of record at December 31, 2006.

On December 16, 2005, our Board of Directors approved a share repurchase program that authorizes management to repurchase up to $50 million of our outstanding common stock until December 31, 2007, as market conditions warrant and covenants under our existing agreements permit. We may conduct our share repurchases in the open-market and in privately negotiated transactions. The repurchase program does not require us to acquire any specific number of shares and may be terminated at any time. No shares were repurchased during 2006 or 2005 under this program.

Cash dividends declared for 2006 on our common stock totaled 50 cents per share including: a dividend of 12.5 cents per share declared on February 23, 2006 and paid April 3, 2006; a dividend of 12.5 cents per share declared on April 27, 2006 and paid on July 3, 2006; a dividend of 12.5 cents per share declared on July 20, 2006 and paid on October 2, 2006; and a dividend of 12.5 cents per share declared on October 24, 2006 and paid on January 2, 2007.

On February 22, 2007, our Board of Directors declared a quarterly dividend of 12.5 cents per share on our common stock. The dividend is payable April 1, 2007 to shareholders of record on March 15, 2007.

The declaration and payment of dividends is subject to the discretion of our Board of Directors. Future dividends will depend on various factors, including our financial condition, earnings, cash requirements, legal requirements, restrictions in agreements governing our outstanding indebtedness, and other factors deemed relevant by our Board of Directors. For a discussion of the restrictions on our ability to declare and pay dividends, see Note 12 of the Notes to Consolidated Financial Statements.

The following table shows the high and low prices of our common stock on the NYSE for each of the last eight quarters.

The performance graph showing the five-year cumulative total return on our common stock as compared to Lubrizol, specialty chemical companies, and the S&P 500 is shown below. The graph assumes $100 invested on the last day of December 2001. Dividends are assumed to be reinvested quarterly.

ITEM 7.    MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATION

Forward-Looking Statements

The following discussion contains forward-looking statements about future events and expectations within the meaning of the Private Securities Litigation Reform Act of 1995. We have based these forward-looking statements on our current expectations and projections about future results. When we use words in this document, such as “anticipates,” “intends,” “plans,” “believes,” “estimates,” “expects,” and similar expressions, we do so to identify forward-looking statements. Examples of forward-looking statements include statements we make regarding future prospects of growth in the petroleum additives market, the level of future declines in the market for TEL, our ability to maintain or increase our market share, and our future capital expenditure levels.

We believe our forward-looking statements are based on reasonable expectations and assumptions, within the bounds of what we know about our business and operations. However, we offer no assurance that actual results will not differ materially from our expectations due to uncertainties and factors that are difficult to predict and beyond our control.

These factors include, but are not limited to, timing of sales orders, gain or loss of significant customers, competition from other manufacturers, resolution of environmental liabilities, changes in the demand for our products, significant changes in new product introduction, increases in product cost, the impact of fluctuations in foreign exchange rates on reported results of operations, changes in various markets, geopolitical risks in certain of the countries in which we conduct business, and the impact of consolidation of the petroleum additives industry. In addition, certain risk factors are also discussed in Item 1A, “Risk Factors.”

You should keep in mind that any forward-looking statement made by us in this discussion or elsewhere speaks only as of the date on which we make it. New risks and uncertainties arise from time to time, and it is impossible for us to predict these events or how they may affect us. We have no duty to, and do not intend to, update or revise the forward-looking statements in this discussion after the date hereof, except as may be required by law. In light of these risks and uncertainties, you should keep in mind that any forward-looking statement made in this discussion, or elsewhere, might not occur.

OVERVIEW

The 2006 year reflected increases in net sales, as well as operating profit, across both lubricant additives and fuel additives as compared to 2005 and 2004. We supply our customers with a diverse portfolio of products to meet their business needs and we believe this is reflected in our results. While the petroleum additives industry experienced escalating raw material costs in 2006, we were generally able to recover these costs through improved pricing and the introduction of more cost-effective products. Our production facilities are operating at high levels and we are selling a product mix with higher margins. As expected, the TEL market continues to decline and segment operating results are lower than last year.

Our balance sheet remains strong at year-end 2006. Our investment in working capital has increased over December 31, 2005 levels in support of our business. We continue to have no outstanding bank debt. In late 2006, we completed the refinancing of both our 8.875% senior notes due 2010 and senior credit facility, providing us with more favorable terms and greater flexibility as we look to the future.

RESULTS OF OPERATIONS

Net Sales

Continuing the trend from the last two years, 2006 net sales increased in essentially all areas of the petroleum additives segment. In addition, total consolidated net sales were higher in 2006 than in either 2005 or 2004. When comparing 2006 with 2005, net sales increased 17%. The increase between 2005 and 2004 was 20%.

28

Table of Contents

In 2006, 2005, and 2004, net sales to two customers of our petroleum additives segment exceeded 10% of total net sales. Sales to BP amounted to $127 million (10% of net sales) in 2006, $112 million (10% of total net sales) in 2005, and $99 million (11% of total net sales) in 2004. Sales to Shell amounted to $169 million (13% of total net sales) in 2006, $143 million (13% of total net sales) in 2005, and $119 million (13% of total net sales) in 2004. These net sales represent a wide-range of products sold to these two customers in multiple regions of the world.

No other single customer accounted for 10% or more of our total net sales in 2006, 2005, or 2004.

The following table shows our net sales by segment for each of the last three years.

Net Sales by Segment

Petroleum Additives—Our petroleum additives sales improved over both 2005 and 2004.

When comparing 2006 to 2005, petroleum additives net sales were up $185 million or 17%. The increase was across both lubricant additives and fuel additives. Increases in selling prices resulted in most of the improvement in net sales, with changes in the mix of products sold also contributing to the higher net sales. Total shipments were essentially unchanged comparing 2006 to 2005. The change in net sales between the two years also includes a small unfavorable foreign currency impact.

Petroleum additives net sales for 2005 increased $182 million, or 21%, over 2004 levels. The increase was across all product lines. Shipments were approximately 7% higher than in 2004 with the increase predominantly in the engine oil additives product line. There were smaller increases in industrial additives and fuel additives product lines. Price increases and a favorable foreign currency impact also contributed to the higher net sales.

The approximate components of the petroleum additives increase in net sales of $185 million when comparing 2006 to 2005 and $182 million when comparing 2005 to 2004 are shown below in millions.

Tetraethyl Lead—Most of the TEL marketing activity is through the marketing agreements with Innospec, under which we do not record the sales transactions. Therefore, the TEL net sales shown above are those made by our wholly-owned subsidiary, Ethyl, in areas not covered by the Innospec marketing agreements. The sales made in areas not covered by the marketing agreements are minor compared to the TEL sales made through the Innospec marketing agreements. See Note 3 of the Notes to Consolidated Financial Statements.

TEL net sales in areas not covered by the Innospec marketing agreements were up slightly in 2006 over 2005 and 2004. This increase primarily represents price increases in 2006.

Segment Operating Profit

NewMarket evaluates the performance of Afton’s petroleum additives business and Ethyl’s TEL business based on segment operating profit. NewMarket Services departments and other expenses are billed to Afton and Ethyl based on the services provided under the holding company structure pursuant to service agreements between NewMarket Services and Afton and NewMarket Services and Ethyl. Depreciation on segment property, plant, and equipment, and amortization of segment intangible assets and the prepayments for services are included in the operating profit of each segment.

The table below reports operating profit by segment for the last three years. The “Contract manufacturing and other” classification in the table below primarily represents certain manufacturing operations that Ethyl provides to Afton. Certain prior period amounts have been reclassified to conform to the current presentation.

Segment Operating Profit

Petroleum Additives—Petroleum additives operating profit for 2006 increased $44 million, or 74%, when compared to the 2005 level of $60 million. Operating profit for 2006 includes a gain of $3 million associated with a legal settlement related to transportation charges, as well as a gain of $6 million resulting from a class action lawsuit related to raw materials and a loss of $5 million from other legal settlements. The increase in operating profit was in both lubricant and fuel additives reflecting improved net sales and profit margins. Net sales were approximately 17% higher than 2005 reflecting improved pricing and improvements in product mix.

While raw material costs escalated in 2006, we were able to implement certain price increases. These price increases have enabled us to restore our margins that have been under pressure since the significant increase in raw material costs began in 2004. Our production facilities are operating at high rates and we are selling more efficient product formulations. These improved product formulations lower both our cost, as well as our customers’ costs. The 2006 results also include a small, unfavorable foreign currency impact.

Petroleum additives operating profit for 2005 was approximately $60 million, an increase of $18 million, or 43%, over 2004. The increases were primarily in the engine oil additives, industrial additives, and certain fuel additives product lines. While net sales of our remaining fuel additives products also increased, higher raw material costs caused operating profit from these products to be considerably lower in 2005 than in 2004.

Overall, the increase in operating profit in 2005 as compared to 2004 resulted from 21% higher net sales and 7% higher shipments. The impact of the increases in selling prices that we were able to achieve during the year substantially covered the increases in raw material costs for 2005, with higher shipments accounting for most of the improved profitability. Both 2005 and 2004 results include a favorable foreign currency impact, primarily from the European Union Euro. The 2004 results also include a gain of about $1 million from an environmental insurance settlement.

Total R&D was $70 million in 2006 and $65 million in both 2005 and 2004. The increase in R&D when comparing 2006 and 2005 is across all product lines, but mainly in engine oil additives. While our R&D expenses were the same in both 2005 and 2004, the projects and product lines that were researched were quite different. This is normal for our business and is a function of industry specifications, customers’ expectations, and competitive forces. There was also a small favorable foreign currency impact in 2006, but a small unfavorable foreign currency impact in 2005 and 2004. R&D related to new products and processes was $37 million in 2006, $34 million in 2005, and $33 million in 2004. All of our R&D expenses were related to the petroleum additives segment.

30

Table of Contents

Selling, general, and administrative expenses (SG&A) in 2006 for this segment were approximately $10 million higher than 2005, while 2005 was approximately $3 million higher than 2004. The increase in 2006 primarily resulted from higher professional fees and personnel-related expenses. The increases in both 2005 and 2004 included the impact of an unfavorable foreign currency effect. As a percentage of net segment sales, SG&A combined with R&D expenses were 12.7% in 2006, 13.5% in 2005, and 16.0% in 2004. The improvement in the percentages when comparing each of the years reflects larger increases in net sales as compared to the smaller increases in SG&A and R&D.

Tetraethyl Lead—Results of our TEL segment include the operating profit contribution from our marketing agreements and certain TEL operations not included in the marketing agreements.

The operating profit contribution from our marketing agreements was $8 million in 2006, $23 million in 2005, and $33 million in 2004. As expected, volumes shipped declined when comparing both 2006 to 2005 and 2005 to 2004. Volumes were 62% lower for 2006 compared to 2005 and 27% lower when comparing 2005 and 2004. Pricing did improve when comparing 2006 to 2005 and 2005 to 2004. In addition, amortization of the prepayment for services was approximately $2 million lower in 2006 than in 2005 and $1 million lower in 2005 than in 2004, reflecting the declining balance method of amortization. These improvements were not enough to offset the impact on operating profit from the decrease in shipments. The decrease in volumes shipped primarily reflects the result of certain of the major TEL customers under the marketing agreement discontinuing use of the product, as well as the ongoing decline in the market as other customers discontinue use of the product.

See Note 3 of the Notes to Consolidated Financial Statements for additional information on the TEL marketing agreements. The TEL market will continue to decline as customers discontinue use of the product.

The loss from other TEL operations that was not a part of the marketing agreements was unchanged when comparing 2006 to 2005 and approximately $9 million unfavorable when comparing 2005 to 2004. The large prior year variances were primarily due to certain insurance settlements. While there were none during 2006, the 2005 results include a special item of $4 million for an insurance settlement gain related to our premises asbestos liabilities. The 2004 results include a special item gain of $12 million from an environmental insurance settlement.

The 2006 results in other TEL operations include a favorable impact from lower environmental expenses compared to 2005. This favorable impact in 2006 from environmental charges was mostly offset by the favorable premises asbestos items in 2005. When comparing 2005 and 2004, the 2005 other TEL operations results include lower premises asbestos charges reflecting the favorable impact of a change in expected future insurance reimbursements. The favorable impact from the premises asbestos items in 2005 was partially offset by an increase in environmental clean-up costs.

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

Special Item Income

Special item income was $15 million in 2006 and included a $5.3 million gain related to an earn-out agreement for certain pharmaceutical intellectual property that was sold in 1994; a $3.3 million gain associated with a legal settlement related to transportation charges; a $5.5 million gain resulting from a class action lawsuit related to raw materials; a $2.5 million loss from a legal settlement; and a $3.3 million gain on the sale of property.

Special item income was $12 million in 2005 and included an aggregate $8 million of gains on the sales of corporate property and a $4 million gain on an insurance settlement related to our premises asbestos liabilities discussed below.

31

Table of Contents

During the second quarter 2005, we entered into an agreement with Travelers resolving certain long-standing issues regarding our coverage for certain premises asbestos claims. In addition, our agreement with Travelers provides a procedure for allocating defense and indemnity costs with respect to future premises asbestos claims. The lawsuit we had previously filed against Travelers in the Southern District of Texas was dismissed.

In 2005, we also settled our outstanding receivable from Albemarle for premises asbestos liability obligations. As a result of the insurance settlement described above, the outstanding amount owed to us by Albemarle was adjusted to $1.4 million, compared to $4 million at year-end 2004. Albemarle paid us $1.4 million in the third quarter of 2005.

The net gain of $4 million in 2005 represents amounts paid to us to settle historical claims in excess of the receivables we carried on our financial statements from both Travelers and Albemarle in the aggregate. This amount is reflected in TEL segment operating profit as discussed above.

Special item income was $13 million in 2004 and represents the gain on an environmental insurance settlement. The terms of the settlement provide for a total payment of $16 million. In addition to the $8 million received during 2004, we received $4 million in February 2005 and the remaining $4 million in February 2006 in accordance with a previously agreed-upon payment schedule.

Interest and Financing Expenses

Interest and financing expenses were $15 million in 2006, $17 million in 2005, and $18 million in 2004. The decrease resulted primarily from lower debt during 2006 as compared to 2005. We had no drawn bank debt under our revolving credit facility during 2006. Fees and amortization costs were substantially unchanged between the two periods excluding the effect of the loss on the early extinguishment of debt.

Lower average debt when comparing 2005 to 2004 resulted in a $1.6 million reduction in interest and financing expenses, while higher average interest rates resulted in increased expenses of $800 thousand. Fees and amortization of financing costs were $600 thousand lower for 2005.

Loss on Early Extinguishment of Debt

In December 2006, we purchased $149.75 million of the outstanding $150 million aggregate principal amount of our 8.875% senior notes due 2010 in a tender offer. As a result of the transaction, we recognized a loss of $11 million on the early extinguishment of debt. This loss included the write-off of unamortized deferred financing costs of $2.6 million and cash paid of $8.6 million related to the premium and other costs of the purchase of the 8.875% senior notes.

Other Income, Net

Other income, net was $7 million in 2006, $900 thousand in 2005, and $300 thousand in 2004. The 2006 amount included a $4 million gain on interest income from an income tax settlement, as well as $2 million investment income. Both 2005 and 2004 were comprised of a number of small items.

Income Tax Expense

Income tax expense was $31 million in 2006, $15 million in 2005, and $12 million in 2004. The effective tax rate was 34.7% in 2006, 25.6% in 2005, and 25.9% in 2004. The effective tax rate in each year reflects certain foreign and other tax benefits.

The increase in income before income taxes from 2005 to 2006 resulted in an increase of $8 million in income taxes in 2006. The increase in the effective tax rate from 2005 to 2006 also resulted in an increase of

32

Table of Contents

$8 million in income taxes in 2006. Part of the rate increase in 2006 relates to the strengthening of foreign currencies resulting in a $2.6 million increase in the tax provision on undistributed earnings of foreign subsidiaries in 2006, while weakening currencies in 2005 resulted in a tax credit of $2.2 million. The 2005 and 2004 rates include the favorable impact of approximately $1 million from the settlement of certain open tax years with the IRS.

The increase in income before income taxes from 2004 to 2005 resulted in the full $3 million increase in taxes between the two years. The effective tax rate between the two years was essentially unchanged.

To comply with international trade rules, the American Jobs Creation Act of 2004 (the Act), signed into law on October 22, 2004, repealed the FSC Repeal and Extraterritorial Income Exclusion Act of 2000. The Act repealed the Extraterritorial Income Exclusion for transactions entered into after December 31, 2004 subject to a phase-out that allowed current beneficiaries to claim benefits in 2005 and 2006. In 2005, the benefit of excluding $6 million from taxable income was 80% of the amount calculated under prior law. In 2006, the benefit of excluding approximately $5 million from taxable income was 60% of the amount calculated under prior law. For 2007 and beyond, no benefit will be allowed.

Our deferred taxes are in a net asset position. Based on current forecast operating plans, we believe that we will recover the full benefit of our deferred tax assets. See Note 22 of the Notes to Consolidated Financial Statements for details on income taxes.

Net Income

Net income was $57.5 million ($3.30 per diluted share) in 2006, $42.4 million ($2.45 per diluted share) in 2005, and $33.1 million ($1.92 per diluted share) in 2004.

CASH FLOWS DISCUSSION

We generated cash from operating activities of $37 million in 2006, $64 million in 2005, and $37 million in 2004.

During 2006, we realized cash flows of $3 million from the sale of property, as well as $5 million from a payment under an earn-out agreement related to our pharmaceuticals business, which we sold in 1994. In addition, we had gross proceeds of $150 million from the issuance of our 7.125% senior notes due 2016. We used these proceeds, as well as the cash from operations to purchase $149.75 million of our 8.875% senior notes due 2010, fund capital expenditures of $26 million, acquire an intangible asset for $4 million, pay dividends on our common stock of $9 million, and pay debt issuance costs of $4 million. Our book overdrafts decreased $2 million. These items resulted in an increase of $4 million in cash and cash equivalents. Fluctuations in foreign currency rates resulted in a favorable impact of $1 million on cash and cash equivalents throughout 2006. Included in the 2006 cash flows from operating activities were collections of $11 million from settlements, including $4 million related to the 2004 environmental insurance settlement discussed below, as well as payments of $18 million to fund our pension plans and $9 million for costs related to the early extinguishment of our 8.875% senior notes. Cash flows from operating activities for 2006 also included an increase in working capital requirements, which are discussed more fully under “Working Capital.”

In 2005, we realized $14 million in before-tax proceeds from the sales of corporate assets. We used these proceeds, as well as the cash flows from operating activities, to fund capital expenditures of $18 million and pay-off our outstanding bank debt of $30 million. Our book overdrafts decreased $1 million. These items resulted in an increase in cash and cash equivalents of $28 million. Cash and cash equivalents throughout 2005 included a $1 million negative impact from foreign currency. Included in the 2005 cash flows from operating activities were collections of $4 million related to the 2004 environmental insurance settlement, which provides for a total payment of $16 million ($8 million of which we received in 2004, $4 million of which we received in 2005 and

33

Table of Contents

$4 million of which we received in February 2006 in accordance with a previously agreed-upon payment schedule) and $7 million from the 2005 insurance settlement related to our premises asbestos liabilities, as well as payments of $12 million to fund our pension plans.

In 2004, we used the cash flows from operating activities, as well as $1 million of proceeds from the exercise of stock options and $5 million cash on hand, to fund capital expenditures of $15 million, to make a net repayment on bank debt of $24 million, to pay debt issuance costs of $1 million, and to purchase certain property for $3 million. Our book overdrafts increased $1 million. Included in the cash flows from operating activities was $8 million related to the 2004 environmental insurance settlement. In addition, cash flows from operating activities included cash outlays of approximately $12 million to fund our pension plans.

Excluding the construction of the office building by our wholly-owned subsidiary, Foundry Park I, we expect that cash from operations, together with borrowing available under our senior credit facility, will continue to be sufficient to cover our operating expenses and planned capital expenditures for the foreseeable future. For more information on the construction of the office building by Foundry Park I, see “Recent Developments” in Part I, Item 1.

FINANCIAL POSITION AND LIQUIDITY

Cash

At December 31, 2006, we had cash and cash equivalents of $60 million as compared to $56 million at the end of 2005.

We also had restricted cash of $200 thousand at December 31, 2006 and $1.4 million at December 31, 2005. In addition, at December 31, 2006, we had restricted funds of $1 million recorded as a long-term asset in other assets. Of these total restricted funds at December 31, 2006, $700 thousand was cash received from Metropolitan Life Insurance Company (Metropolitan) during 2005 and 2003. These funds amounted to $900 thousand at December 31, 2005. The funds from Metropolitan are being used to reduce the employee portion of retiree health benefit costs. The remaining $500 thousand of restricted funds at both December 31, 2006 and December 31, 2005 represents funds related to the issuance of a European bank guarantee.

At both December 31, 2006 and December 31, 2005, we had a book overdraft for some of our disbursement cash accounts. A book overdraft represents disbursements that have not cleared the bank accounts at the end of the reporting period. We transfer cash on an as-needed basis to fund these items as they clear the bank in subsequent periods.

Debt

Senior Notes—On November 21, 2006, we commenced a cash tender offer for any and all $150 million aggregate principal amount of our then outstanding 8.875% senior notes due 2010. Upon the expiration of the tender offer on December 21, 2006, we accepted for purchase and purchased $149.75 million aggregate principal amount of our 8.875% senior notes. As a result of this transaction, we recognized a loss of $11 million on the early extinguishment of debt. The loss included the write-off of $2.6 million in unamortized deferred financing costs and cash paid of $8.6 million related to the premium and other costs of the purchase of the 8.875% senior notes. We redeemed the remaining outstanding $250 thousand aggregate principal amount of our 8.875% senior notes on February 7, 2007.

On December 12, 2006, we issued $150 million aggregate principal amount of our 7.125% senior notes due 2016. The purchase of our 8.875% senior notes in the tender offer was financed with net proceeds from the issuance of the 7.125% senior notes, as well as cash on hand.

34

Table of Contents

The 7.125% senior notes are our senior unsecured obligations and are jointly and severally guaranteed on an unsecured basis by all of our existing and future wholly-owned domestic restricted subsidiaries. We incurred financing costs of approximately $3 million related to the 7.125% senior notes, which are being amortized over ten years.

The 7.125% senior notes and the subsidiary guarantees rank:

The indenture governing the 7.125% senior notes contains covenants that, among other things, limit our ability and the ability of our restricted subsidiaries to:

We were in compliance with the covenants in the indenture governing the 7.125% senior notes as of December 31, 2006 and those in the indenture governing the 8.875% senior notes as of December 31, 2006.

Senior Credit Facility—On December 21, 2006, we entered into a Second Amended and Restated Credit Agreement. This credit agreement amended and restated the credit agreement that we entered into on June 18, 2004.

The credit agreement includes a $100 million revolving senior credit facility. We have an option to increase the senior credit facility commitment by an amount not to exceed $50 million, subject to the satisfaction of certain terms and conditions. We incurred additional financing costs of approximately $600 thousand, which resulted in total unamortized deferred financing costs of approximately $3 million related to the senior credit facility. These costs are being amortized over five years.

The $100 million senior credit facility is for working capital and other general corporate purposes for NewMarket and our subsidiaries and includes a $50 million sub-facility for letters of credit. Borrowings bear interest, at our election, at either a base rate plus a margin (25 basis points as of December 31, 2006) or LIBOR plus a margin (125 basis points as of December 31, 2006). The revolving credit facility matures on December 21, 2011. There were no borrowings outstanding at December 31, 2006 under the senior credit facility. At December 31, 2006, we had outstanding letters of credit of $3.5 million, resulting in the unused portion of the senior credit facility amounting to $96.5 million.

The senior credit facility is secured by liens on a significant portion of our U.S. assets. In addition, the senior credit facility is guaranteed by our U.S. subsidiaries.

35

Table of Contents

The credit agreement contains covenants, representations, and events of default that management considers typical of a credit agreement of this nature. The financial covenants include:

We were in compliance with these covenants at December 31, 2006.

* * *

We had combined current and noncurrent long-term debt of $153.4 million at December 31, 2006 and $153.8 million at December 31, 2005.

During 2005, we paid-off our bank debt under our previous credit agreement which amounted to $30 million. We also paid $600 thousand on the capital lease obligations. All of our debt is discussed more fully in Note 12 of the Notes to Consolidated Financial Statements.

As a percentage of total capitalization (total long-term debt and shareholders’ equity), our total debt decreased from 36.6% at the end of 2005 to 33.7% at the end of 2006. The decrease reflects the increase in shareholders’ equity due to earnings, as well as the small pay down of debt. Normally, we repay long-term debt with cash from operations, as well as with proceeds from occasional sales of business units, plant sites, or other assets.

Working Capital

At December 31, 2006, we had working capital of $302 million, resulting in a current ratio (which is defined as current assets divided by current liabilities) of 2.88 to 1. Our working capital at year-end 2005 was $245 million resulting in a current ratio of 2.47 to 1.

The increase in working capital primarily reflects higher accounts receivable and inventories. The increase in accounts receivable is equally due to longer payment terms than in the past, as well as higher past due amounts at December 31, 2006. The increase in inventories results from higher raw material costs, as well as an increase in volumes in support of increased customer demands and our manufacturing plans.

Capital Expenditures

Excluding the construction of the office building by Foundry Park I, a wholly-owned subsidiary of NewMarket Development, we expect capital expenditures to be approximately $30 million in 2007. We expect to continue to finance this capital spending through cash provided from operations, together with borrowing available under our senior credit facility. For more information on the construction of the office building by Foundry Park I, see “Recent Developments” in Part I, Item 1.

Environmental Expenses

We spent approximately $16 million in 2006, $13 million in 2005, and $14 million in 2004 for ongoing environmental operating and clean-up costs, excluding depreciation of previously capitalized expenditures. These environmental operating and clean-up expenses are included in cost of goods sold. In 2007, we expect environmental operating and remediation costs to be about the same as 2006. Further, we expect to continue to fund these costs through cash provided by operations.

Contractual Obligations

The table below shows our year-end contractual obligations by year due.

Purchase orders made in the ordinary course of business are excluded from the above table. Any amounts for which we are liable under purchase orders are reflected in our Consolidated Balance Sheets as accounts payable and accrued liabilities.

Under the marketing agreements with Innospec, we are required to provide approximately one-third of the cost of product sold to customers in the territory from our TEL inventory or post an equivalent dollar value deposit with Innospec. The approximate requirement is $12 million at year-end 2006 and $13 million at year-end 2005. We now cover this requirement of the marketing agreements through the value of a working capital advance to Innospec. This advance is being repaid to Ethyl as the requirement decreases and will be repaid in full at the end of the marketing agreements. These amounts have been recorded in other assets and deferred charges on the Consolidated Balance Sheets. See Note 9 of the Notes to Consolidated Financial Statements.

Pension and Postretirement Benefit Plans

We apply SFAS No. 87, “Employers’ Accounting for Pensions”, SFAS No. 106, “Employers’ Accounting for Postretirement Benefits Other Than Pensions”, and SFAS No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” to account for our pension and postretirement plans. We use a

December 31 measurement date to determine our pension and postretirement expenses and related financial disclosure information. Additional information on our pension and postretirement plans is in Note 18 of the Notes to Consolidated Financial Statements.

Investment Return Assumptions under SFAS 87 and Asset Allocation—We periodically review our assumptions for the long-term expected return on pension plan assets. As part of the review and to develop expected rates of return, we considered, with the assistance of our independent consulting actuaries, a stochastic analysis of expected returns based on the domestic plans’ asset allocation as of both January 1, 2005 and January 1, 2006. This forecast reflects our expected long-term rates of return for each significant asset class or economic indicator. As of January 1, 2007, the expected rates were 9.1% (9.4% last year) for U.S. large cap stocks, 6.3% (5.7% last year) for U.S. long-term corporate bonds, and 2.7% (2.8% last year) for inflation. The range of returns developed relies both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class.

Our asset allocation is predominantly weighted toward equities. Through a review of our investments and after reducing our long-term rate of return by 25 basis points at December 31, 2005, we have determined that we should maintain the expected long-term rate of return for our domestic plans at 8.75% at December 31, 2006.

An actuarial gain, where the actual return exceeds the expected return, occurred during 2006 resulting in the actual investment return exceeding the assumed return in 2006 by approximately $3 million for all of our domestic pension plans. Despite the actuarial gain for 2006, we continue to have a net unrecognized loss at December 31, 2006. Actuarial losses, where the actual return was less than the expected return, resulted during 2005 and 2004. The one-year investment return was lower than the long-term assumption by approximately $4 million in 2005 and $1 million in 2004 for all of our domestic pension plans. Investment losses enter earnings on an amortized basis so that recent years’ losses resulted in increased expense of approximately $400 thousand in 2006, as well as an expected $40 thousand increased expense in 2007. We expect that there will be continued volatility in pension expense as actual investment returns vary from the expected return, but we continue to believe the potential benefits justify the risk premium for equity investments.

Pension expense is sensitive to changes in the expected return on assets. For example, decreasing the expected rate of return by 25 basis points to 8.50% (while holding other assumptions constant) would increase the forecasted 2007 expense for our domestic pension plans by approximately $200 thousand. Similarly, a 25 basis point increase in the expected rate of return to 9.00% (while holding other assumptions constant) would reduce forecasted 2006 pension expense by approximately $200 thousand.

Discount Rate Assumption under SFAS 87 and SFAS 106—We utilize the Citigroup Pension Discount Curve (discount curve) and Liability Index in developing the discount rate assumption. We apply the expected cash flows of the specific defined benefit retirement plan to the interest rates provided in the discount curve. The rate is developed based on the discount curve on the last day of December. The discount rate at December 31, 2006 was 5.875%.

Pension expense is also sensitive to changes in the discount rate. For example, decreasing the discount rate by 25 basis points to 5.625% (while holding other assumptions constant) would increase the forecasted 2007 expense for our domestic pension plans by approximately $400 thousand. A 25 basis point increase in the discount rate to 6.125% would reduce forecasted 2007 pension expense by approximately $300 thousand.

Rate of Projected Compensation Increase—We have maintained our rate of projected compensation increase at December 31, 2006 at 3.75%. The rate assumption was based on an analysis of our projected compensation increases for the foreseeable future.

Liquidity—Cash contribution requirements to the pension plan are sensitive to changes in assumed interest rates in the same manner as pension expense. We expect our aggregate domestic cash contributions, before income taxes, will be approximately $7 million in 2007 while foreign cash contributions will be approximately $8 million.

Other Assumptions under SFAS 106—During 2002, we reviewed our assumption for the health care cost trend rate under SFAS 106. This review was done with reference to cost increases in our own plans, as well as broader market increases in employer-provided health care costs and observations of SFAS 106 assumptions used by other large employers. Consequently, as of December 31, 2002, we increased our assumption for the health care cost trend rate substantially to a rate of 11% in 2002 scaling down to 5.5% over the next ten years. Previously, the health care cost trend rate was 6% to 7%. The assumption of declining inflation is consistent with the expectation that medical cost increases will abate after several years of double-digit growth. We have reviewed these assumptions and believe they continue to be appropriate for 2006.

The expected long-term rate of return on our postretirement plans is 7%. This rate varies from the pension rate of 8.75% primarily because of the difference in investment of assets. The assets of the postretirement plan are held in an insurance contract, which results in a lower assumed rate of investment return.

OUTLOOK

We believe we are in a strong financial position today. Our overall strategy remains unchanged. It is our intent to leverage our financial strength to grow the business, with acquisitions being an area of primary interest. Our primary focus in the acquisition area remains on the petroleum additives industry. We believe that in the current mergers and acquisition environment, this industry will provide the greatest opportunity for a good return on investment while minimizing risk. As we have stated in the past, we remain patient in this pursuit. We have many internal opportunities for growth in the near term, from both geographical and product line extensions. We will wait and make the right acquisition for our company when the opportunity arises.

During 2006, we restructured our debt by purchasing our 8.875% senior notes in a tender offer, issuing new 7.125% senior notes, and amending and restating the credit agreement governing our senior credit facility. The new senior notes and credit agreement provide us with lower interest rates and terms that more accurately reflect our improved financial position. With no bank debt outstanding, we continue to build cash on the balance sheet. We are considering a full range of uses for this cash.

Early in 2007, we announced our intention to develop some of the downtown Richmond property that we own by constructing a multi-story office building for MeadWestvaco. We plan to invest between approximately $110 million and $140 million in completing construction of the building. We expect to primarily finance this project through construction and permanent indebtedness. Significant needs for cash for this project will not begin until 2008.

We will also be investigating a range of other investments. We will balance all of these options with the likelihood of merger and acquisition activity and decide on the best course of action to increase shareholder value.

Petroleum Additives

By any measure, 2006 was an outstanding year for our petroleum additives segment. We continue to focus on growing our business by helping our customers be successful in their marketplace. Our strategy is twofold: cost management in those areas that are commodity-like in their characteristics through reformulations and new component introduction and growth through product differentiation in the other areas where margins are higher.

We expect that our approach in 2007 will be much the same. As in any year, there are many variables which will determine the ultimate profit achieved for the year. Raw material costs remain a significant unknown. We continue to expect significant volatility during 2007 in the cost of raw materials that are related to crude oil and natural gas. Base oil pricing has decreased at the beginning of 2007. This is primarily a result of higher inventories which may not be sustained as demand increases or as plant turnarounds occur in early 2007. However, prices of other raw materials, such as polyisobutylene, alpha olefins, 2-ethylhexanol, and

39

Table of Contents

ethyleneamine, continue to stay firm. In fact, many raw materials we buy today tend to be governed by the supply and demand balance in their own market. On the demand side, worldwide usage remains strong. Our plants continue to operate at very high rates and we anticipate no slowdown during the year. As is a constant feature of our business, the costs continue to escalate. Our R&D investment increased by 7% in 2006 over 2005 and we expect it to increase again this year. The newly adopted REACH legislation in Europe will further increase our costs. We have worked hard in the past year to provide better, more cost effective products to our customers. As a result our margins have improved during 2006.

We expect to continue on the successes of 2006 and expect that petroleum additives will have a higher operating profit in 2007 than 2006.

TEL

This segment took a significant step-down in its overall contribution to our results during 2006. This product is being phased out around the world and we expect it to remain a very small contributor to our overall profits. Our plans are to continue to manage costs within this business and to raise prices to reflect the economic value of the product.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

It is our goal to clearly present our financial information in a manner that enhances the understanding of our sources of earnings and cash flows, as well as our financial condition. We do this by including the information required by the SEC, as well as additional information that gives further insight into our financial operations.

Our financial report includes a discussion of our accounting principles, as well as methods and estimates used in the preparation of our financial statements. We believe these discussions and statements fairly represent the financial position and operating results of our company. The purpose of this portion of our discussion is to further emphasize some of the more critical areas where a significant change in facts and circumstances in our operating and financial environment could cause a change in reported financial results.

TEL Marketing Agreements Services

As discussed in various sections of this Annual Report on Form 10-K, we have made certain payments related to our TEL marketing agreements. We made the final payment of $3 million in 2003. The unamortized total is $8 million at December 31, 2006. We are amortizing these costs on an accelerated basis using a declining balance method over the life of the contracts. We believe this is the appropriate methodology and time period for this amortization based on the facts and circumstances of our TEL operations and the estimated product life of TEL. The customer base of TEL is significantly concentrated in a few countries and when conditions change that cause a shorter product life or other restrictions outside of our control, the amortization period is adjusted accordingly. Any adjustment to the amortization period would impact earnings, but would have no effect on cash flows. We continue to keep our accounting for this issue current with the business conditions.

The total amortization related to the TEL marketing agreements is currently projected to be:

Intangibles, Net of Amortization

We also have certain identifiable intangibles amounting to $52 million at year-end 2006 that are discussed in Note 10 of the Notes to Consolidated Financial Statements. These intangibles relate to our petroleum additives business and are being amortized over periods with up to ten years of remaining life. We continue to assess the market related to these intangibles, as well as their specific values, and have concluded the amortization periods and values are appropriate. We also evaluate these intangibles for any potential impairment when significant events or circumstances occur that might impair the value of these assets. These evaluations continue to support the value at which these identifiable intangibles are carried on our financial statements. However, if conditions were to substantially deteriorate in this market, it could possibly cause a reduction in the periods of this amortization charge or result in a noncash write-off of a portion of the intangibles’ carrying value. A reduction in the amortization period would have no effect on cash flows. While we do not anticipate such a change in the market conditions, this disclosure is provided to enhance the understanding of the factors involved.

Environmental

We have made disclosure of our environmental matters in Item 1 of this Annual Report on Form 10-K, as well as in the Notes to Consolidated Financial Statements. We believe our environmental accruals are appropriate for the exposures and regulatory guidelines under which we currently operate. While we currently do not anticipate significant changes to the many factors that could impact our environmental requirements, we continue to keep our accruals consistent with these requirements as they change.

Also, as noted in the discussion of “Legal Proceedings” in Item 3 of this Annual Report on Form 10-K, while it is not possible to predict or determine with certainty the outcome of any legal proceeding, we do not believe that we will experience any material adverse effects on our results of operations or financial condition as a result of any pending or threatened proceeding.

Pension Plans and Other Postretirement Benefits

We use assumptions to record the impact of the pension and postretirement plans in the financial statements. These assumptions include the discount rate, expected long-term rate of return on plan assets, rate of compensation increase, and health-care cost trend rate. A change in any one of these assumptions could result in different results for the plans. We develop these assumptions after considering advice from a major global actuarial consulting firm. Information is provided on the pension and postretirement plans in Note 18 of the Notes to Consolidated Financial Statements. In addition, further disclosure on the effect of changes in these assumptions is provided in the “Financial Position and Liquidity” section of Item 7.

Income Taxes

We file consolidated U.S. federal and state income tax returns, as well as individual foreign income tax returns, under which assumptions may be made to determine the deductibility of certain costs. In addition, we make certain assumptions in the determination of the estimated future recovery of deferred tax assets.

RELATED PARTY TRANSACTIONS

Thomas E. Gottwald, our chief executive officer and a director, is a son of Bruce C. Gottwald, our chairman of the board of directors and our former chief executive officer. The members of the family of Bruce C. Gottwald may be deemed to be control persons of NewMarket. Bruce C. Gottwald owns more than 5% of the outstanding shares of our common stock.

Effective September 24, 2004, NewMarket Services, entered into a Membership Units Purchase and Assignment Agreement (the Agreement), with Bruce C. Gottwald and Floyd D. Gottwald, Jr., who are brothers

(collectively the Gottwalds) and Old Town LLC (Old Town), under which NewMarket Services agreed to purchase all of the voting and non-voting units in Old Town owned by the Gottwalds. The purchase price of $3.3 million was based on an appraisal. The Agreement also provided that each of the Gottwalds must resign as a manager of Old Town. Our Audit Committee and all of our independent directors unanimously approved the Agreement.

Under the terms of the Agreement, in the event that NewMarket Services decides to sell substantially all of the assets of Old Town and receives an offer from a third-party for such assets, NewMarket Services must provide the offer to the Gottwalds, who will have 30 days to purchase the assets of Old Town on the same terms and conditions as contained in the third-party offer.

In April 2001, we had sold this same property, located in King William, Virginia, and consisting of approximately 1,600 acres, to Old Town, which at the time was owned by the Gottwalds, for $2.9 million in cash, which was a value based on appraisals. We managed the property for Old Town.

RECENTLY ISSUED ACCOUNTING STANDARDS

In June 2006, the FASB issued Financial Interpretation 48, “Accounting for Uncertainty in Income Taxes— an interpretation of FASB Statement No. 109” (FIN 48). FIN 48 provides guidelines for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It further clarifies the accounting for uncertainty in income taxes recognized in the financial statements in accordance with Financial Accounting Statement No. 109, “Accounting for Income Taxes.” The interpretation is effective for fiscal years beginning after December 15, 2006. We adopted FIN 48 on January 1, 2007. We currently do not expect FIN 48 to have a material impact on our financial statements; however, we are still finalizing our review.

In September 2006, the FASB issued Statement of Financial Accounting Standard No. 157, “Fair Value Measurements” (SFAS 157). The standard defines fair value, outlines a framework for measuring fair value, and details the required disclosures about fair value measurements. The standard is effective for years beginning after November 15, 2007. We are evaluating the impact of the adoption of SFAS 157 on our financial statements.

ITEM 7A.     QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to many market risk factors, including fluctuations in interest and foreign currency rates, as well as changes in the cost of raw materials and marketable security prices. These risk factors may affect our results of operations, cash flows, and financial position.

We manage these risks through regular operating and financing methods, including the use of derivative financial instruments. When we have derivative instruments, they are with major financial institutions and are not for speculative or trading purposes. Also, as part of our financial risk management, we regularly review significant contracts for embedded derivatives. As of December 31, 2006, based on our review, we had no contracts with an embedded derivative.

The following analysis presents the effect on our earnings, cash flows, and financial position as if the hypothetical changes in market risk factors occurred at year-end 2006. We analyzed only the potential impacts of our hypothetical assumptions. This analysis does not consider other possible effects that could impact our business.

Interest Rate Risk

At December 31, 2006, we had total debt of $153 million with none of that amount at variable interest rates. Because all of our debt at year-end was at a fixed rate, there was no interest rate risk at the end of the year. If we were to borrow under our senior credit facility in the future, we would experience interest rate risk based on the interest rates available to us at that time.

42

Table of Contents

Since all of our debt at year-end 2006 is at a fixed rate, a hypothetical 10% decrease in interest rates, holding all other variables constant, would have resulted in a change of $8 million in fair value of our debt.

Foreign Currency Risk

We sell to customers in foreign markets through our foreign subsidiaries, as well as through export sales from our plants in the United States. These transactions are often denominated in currencies other than the U.S. Dollar. Our primary currency exposures are the European Union Euro, British Pound Sterling, Japanese Yen, and Canadian Dollar.

We sometimes enter into forward contracts as hedges to minimize the fluctuation of accounts receivable denominated in foreign currencies. During 2006, we entered into $15 million of Euro-denominated forward contracts to minimize currency exposure from expected cash flows from foreign operations. The contracts all have maturity dates in 2006 and 2007. At December 31, 2006, there were $6 million remaining of these Euro-denominated contracts. With other variables held constant, a hypothetical 10% adverse change in the December 31, 2006 forward Euro rates would have resulted in a decrease of about $1 million in the value of the contracts.

Raw Material Price Risk

We utilize a variety of raw materials in the manufacture of our products, including base oil, polyisobutylene, olefin copolymers, maleic anhydride, antioxidants, alcohols, and methacrylates. Our profitability is sensitive to changes in the costs of these materials caused by changes in supply, demand or other market conditions, over which we have little or no control. If we experience sudden or sharp increases in the cost of our raw materials, we may not be able to pass on these increases in whole or in part to our customers. Political and economic conditions in the Middle East and Latin America have caused and may continue to cause the cost of our raw materials to fluctuate. War, armed hostilities, terrorist acts, civil unrest or other incidents may also cause a sudden or sharp increase in the cost of our raw materials. If we cannot pass on to our customers any future increases in raw material costs in the form of price increases for our products, there will be a negative impact on operating profit.

FINANCIAL POLICY

NewMarket Corporation’s Financial Standards—Our goal is to present clearly NewMarket’s financial information to enhance your understanding of our sources of earnings and cash flows and our financial condition.

Management’s Report on the Financial Statements—NewMarket prepared the financial statements and related notes in accordance with GAAP. In doing so, management made informed judgments and estimates of the expected effects of certain events and transactions on the reported amounts of assets and liabilities at the dates of the financial statements. The same is true for the reported amounts of revenues and expenses during these reporting periods. Financial data appearing elsewhere in this Annual Report on Form 10-K is consistent with these financial statements. However, actual results could differ from the estimates on which these financial statements are based.

PricewaterhouseCoopers LLP (PwC), an independent registered public accounting firm, audited NewMarket’s consolidated financial statements as of December 31, 2006 and 2005, and for each of the three years in the period ended December 31, 2006, in accordance with the standards of the Public Company Accounting Oversight Board (United States).

The Audit Committee of the Board of Directors, composed only of independent directors, meets with management and PwC to review accounting, auditing, and financial reporting matters. The independent registered public accounting firm is appointed by the Audit Committee.

ITEM 8.     FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of NewMarket Corporation:

We have completed integrated audits of NewMarket Corporation’s consolidated financial statements and of its internal control over financial reporting as of December 31, 2006, in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements

In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of income, shareholders’ equity and cash flows present fairly, in all material respects, the financial position of NewMarket Corporation and its subsidiaries at December 31, 2006 and 2005, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

As discussed in Note 18 to the consolidated financial statements, the Company changed the manner in which it accounts for defined benefit pension and other postretirement plans effective December 31, 2006.

Internal control over financial reporting

Also, in our opinion, management’s assessment, included in Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A, that the Company maintained effective internal control over financial reporting as of December 31, 2006 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control—Integrated Framework issued by the COSO. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management’s assessment and on the effectiveness of the Company’s internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in

44

Table of Contents

accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
