PART I

Item 1. Business

Overview

Nucor Corporation was incorporated in Delaware in 1958. Nucor and affiliates are manufacturers of steel and steel products, with operating facilities and customers primarily located in North America. In February 2008, Nucor acquired The David J. Joseph Company (“DJJ”) and its affiliates. Through DJJ, Nucor also brokers ferrous and nonferrous metals, pig iron and HBI/DRI; supplies ferro-alloys; and processes ferrous and nonferrous scrap.

Nucor is North America’s largest recycler, using scrap steel as the primary material in producing our products. In 2008, we recycled approximately 20 million tons of scrap steel.

Segments

Nucor reports its results in the following segments: steel mills, steel products and raw materials. Net sales to external customers, intercompany sales, depreciation expense, amortization expense, earnings before income taxes, assets and capital expenditures by segment for each of the three years in the period ended December 31, 2008 as well as geographic information for the two years ended December 31, 2008, are set forth in Note 22 of Notes to Consolidated Financial Statements of the 2008 Annual Report, which note is hereby incorporated by reference.

Principal Products Produced

Principal products from the steel mills segment are hot-rolled steel (angles, rounds, flats, channels, sheet, wide-flange beams, pilings, billets, blooms, beam blanks and plate) and cold-rolled steel. Principal products from the steel products segment are steel joists and joist girders, steel deck, fabricated concrete reinforcing steel, cold finished steel, steel fasteners, metal building systems, light gauge steel framing, steel grating and expanded metal, and wire and wire mesh. The raw materials segment produces direct reduced iron (“DRI”) from Nucor’s facility in Trinidad; brokers ferrous and nonferrous metals, pig iron and HBI/DRI; supplies ferro-alloys; and processes ferrous and nonferrous scrap.

Hot-rolled steel is manufactured principally from scrap and scrap substitutes, utilizing electric arc furnaces, continuous casting and automated rolling mills. Cold-rolled steel, cold finished steel, steel joists and joist girders, fabricated concrete reinforcing steel, grating and expanded metal, cold drawn wire and steel fasteners are manufactured by further processing of hot-rolled steel. Steel deck, light gauge steel framing and wire mesh are manufactured from cold-rolled and cold drawn steel.

Markets and Marketing

In the steel mills segment, hot-rolled and cold-rolled sheet steel are produced to customer orders. In addition, other hot-rolled and cold-rolled steel are manufactured in standard sizes and inventories are maintained. In 2008, approximately 89% of the steel mills segment production was sold to non-affiliated customers; the remainder was used internally by the steel products segment. Hot-rolled steel and cold-rolled steel are sold primarily to steel service centers, fabricators and manufacturers throughout the United States. In 2008, approximately 40% of our sheet steel sales were made to contract customers with the balance of sales made in the spot market at prevailing prices at the time of sale. These contracts permit price adjustments to reflect changes in prevailing raw material costs and typically have terms ranging from six to twelve months.

In the steel products segment, steel joists and joist girders, and steel deck are sold to general contractors and fabricators throughout the United States. Substantially all work is to order and no unsold inventories of finished products are maintained. The majority of sales contracts are firm fixed-price contracts and are normally competitively bid against other suppliers. Longer term contracts may permit price adjustments to reflect changes

1

Item 1. Business, continued

in prevailing raw materials costs. Reinforcing products are sold on a construction contract bid basis. Product applications include highways, bridges, reservoirs, utilities, hospitals, schools, airports, stadiums and high-rise buildings. Cold finished steel, steel fasteners, steel grating, wire and wire mesh are manufactured in standard sizes and inventories are maintained. Cold finished steel and steel fasteners are sold primarily to distributors and manufacturers throughout the United States and Canada.

Products from the steel mills and steel products segments are marketed mainly through in-house sales forces. The principal competitive factors are price and service. The markets that Nucor serves are tied to capital and durable goods spending and are affected by changes in economic conditions. Considerable competition exists from numerous domestic manufacturers and foreign imports.

In the raw materials segment, ferrous and nonferrous scrap metal is processed and sold to domestic and international consumers. Additionally, brokerage of scrap substitutes, supply of ferro-alloy, and transportation, material handling and other services are provided to users of scrap metals. The primary customers for ferrous scrap are steel mills and foundries that use scrap as a raw material in their manufacturing process. Nonferrous customers include aluminum can companies, secondary aluminum smelters, steel mills and other processors and consumers of various nonferrous metals. Scrap products and services are marketed through in-house sales forces. In 2008, approximately 20% of the ferrous and nonferrous scrap tons sold by the raw materials segment were to non-affiliated customers.

Due to the global liquidity crisis that has resulted in the rapid weakening of global economic stability, capital spending and the related demand for our products remains depressed. In response, the United States Congress has recently enacted economic stimulus legislation that includes funds for infrastructure that should help capital spending in the months and years to come. This spending package includes “Buy America” language that should benefit our industry. The timing of this stimulus spending is uncertain, however, and we are preparing for a long period of depressed demand.

In the past, unfairly traded steel imports have had a devastating effect on the U.S. steel industry and its workers. We have continued the aggressive trade case work in which we have engaged over the years with our participation in the current statutory five-year sunset reviews of existing duties. In late 2006, the United States International Trade Commission chose to remove the duties that were in place on many of the countries involved in dumping these products into the United States. As a result, more foreign steel has continued to enter our borders with negative effects on several segments of the steel industry. The current economic crisis brings with it a renewed concern that illegally traded steel will once again become a major issue in our market, the world’s most open trading market. The past history of illegally traded steel imports has forced Nucor to become a realist regarding global trade. We will continue to fight illegally dumped foreign steel in support of both free and fair trade.

In 2008, Nucor aggressively supported the adoption of a Chinese Currency bill that would identify the mercantilist practices of currency manipulation that result in distorted trade, an insurmountable trade deficit and the loss of manufacturing jobs in the United States. Several bills were generated in the House and Senate, but none were enacted into law. Our coalition supporting these bills was broad, reaching across multiple industries, and ultimately drew attention to the domestic manufacturing job loss issue. In 2009, we hope that newly proposed legislation will unite Congress in an effort to maintain and enforce laws ensuring free and fair trade. The current Treasury Secretary has said informally that China manipulates its currency. This is a more positive step than anything accomplished by the prior administration. Nucor actively supports several organizations that promote free and fair trade and oppose currency manipulation.

Backlog

In the steel mills segment, Nucor’s backlog of orders was approximately $1.42 billion and $2.74 billion at December 31, 2008 and 2007, respectively. Nucor’s backlog of orders in the steel products segment was

2

Item 1. Business, continued

approximately $1.38 billion and $1.51 billion at December 31, 2008 and 2007, respectively. Order backlogs for the steel mills segment include orders attributable to Nucor’s downstream businesses. The majority of these orders will be filled within one year. The decrease in backlog orders in both segments is due to the economic downturn that occurred in the fourth quarter of 2008 and has continued into 2009. This downturn is severe in the construction markets, which represent a significant percentage of sales for our steel mills and steel products segment. Due to the nature of our raw materials business, order backlog within the raw materials segment is not significant.

Raw Materials

The primary raw material for the steel mills segment is ferrous scrap, which is primarily acquired via DJJ’s brokerage service from numerous sources throughout the country, including our DJJ scrap processing facilities. The primary raw material for the steel products segment is steel, which is almost entirely purchased from the steel mills segment. In the raw materials segment, we purchase ferrous and nonferrous scrap from the following primary sources: (i) manufacturers and industrial plants or other sources which generate or recycle steel scrap, aluminum, copper, stainless steel and other nonferrous metals; and (ii) scrap dealers, peddlers, auto wreckers, demolition firms and others who generate steel which they collect from a variety of sources. We do not purchase a material amount of scrap metal from a single source or from a limited number of major sources. The primary raw material for our DRI facility in Trinidad is iron ore which is purchased from various international suppliers.

The average scrap and scrap substitute cost per ton used remained at historically high levels in 2007 and 2008, increasing 13% from $246 in 2006 to $278 in 2007 and increasing an additional 58% to $438 in 2008. During both years, Nucor used a raw material surcharge as a component of our product pricing to help offset the impact of volatile scrap prices.

Changes in scrap prices are based on changes in the global supply and demand for scrap, which is tied to the global supply and demand for steel products. From late 2003 until third quarter 2008, demand for scrap and other raw materials rose sharply in response to increased demand, both domestically and internationally, for a wide range of products made from steel without a corresponding increase in the global supply of those raw materials. Our surcharges are based upon changes in widely-available market indices for prices of scrap and other raw materials. We monitor those changes closely and make adjustments as needed, but generally on a monthly basis, to the surcharges and sometimes directly to the selling prices, for our products. The majority of our steel sales are to spot market customers who place their orders each month based on their business needs and our pricing competitiveness compared with both domestic and global producers and trading companies. We also include in all of our contracts a method of adjusting prices on a monthly basis to reflect changes in scrap prices. Contract sales typically have a term ranging from six months to two years. Although there will always be a timing difference between changes in the prices we pay for raw materials and the adjustments we make, we believe that the surcharge mechanism, which our customers understand is a necessary response by us to the market forces of supply and demand for our raw materials, has until recently been an effective means of maintaining our margins.

In the fourth quarter, Nucor experienced a rapid fall-off in sales due to weaker market conditions. Since pig iron and certain grades of scrap have lead times of four to six months, dramatically reduced sales volumes resulted in the accumulation of increased tons of inventories (primarily at our steel mills) ordered at peak market prices. Our margins will be reduced until we work through this high priced inventory.

Nucor’s margins and overall profitability are affected by the global balance of supply and demand for steel. Our margins have been much stronger since 2002 and 2003 when most domestic and global steel companies reported operating losses and many filed for bankruptcy. We believe our variable cost structure allowed us to survive those severely depressed market conditions as scrap prices fell dramatically and our incentive pay system reduced our hourly and salary payroll costs, helping to offset lower selling prices. We recognize that the steel business is cyclical in nature and expect to see future changes in the balance of supply and demand impact our

3

Item 1. Business, continued

margins and profitability. We also recognize that the global demand for steel has been growing at close to 6% annually since 2000 reflecting the building of infrastructure in Brazil, Russia, India, China, the Middle East, Eastern Europe, Africa and other parts of Asia. We believe this growth in steel consumption is likely to resume once the global economy emerges from the current severe recession.

The steel mills are also large consumers of electricity and natural gas. Nucor uses cash flow hedges and natural gas purchase contracts to partially manage its exposure to price risk of natural gas that is used during the manufacturing process. Historically, U.S.-based manufacturers have enjoyed competitive energy costs that have allowed them to compete on equal footing in what is becoming more and more a global market. In recent decades, our government has allowed a growing over-reliance on natural gas for the generation of electricity, while delaying or halting the construction of new coal-fired and nuclear power plants. At the same time, our government has prevented access to some of the most promising areas for natural gas exploration. As a result, natural gas prices have increased from less than $2.00 per mmbtu in the 1990’s (NYMEX Henry-Hub pricing) to a peak of more than $15.00 per mmbtu in December 2005. Forward contract prices for 2009 are currently averaging less than $5.00 per mmbtu due to the weak economy and reduced industrial demand. Any form of greenhouse gas legislation is likely to further increase the share of electricity generated by natural gas, thereby increasing costs for consumers of electricity. Nucor actively supports several organizations that are promoting a more rational energy policy. We believe this is critical for not only our future business success, but also for the future of the U.S. economy. Supplies of raw materials and energy have been, and are expected to be, adequate to operate our facilities.

Strategic Growth Initiatives

Nucor employs a multi-pronged growth strategy allowing for flexibility and the ability to capitalize on growth opportunities at any point in time. The objective of our strategy is profitable growth that will allow for maximum shareholder returns. The four prongs include:

• Optimization of existing operations

• Greenfield growth that capitalizes on new technologies and unique marketplace opportunities

• Acquisitions

• International growth with an emphasis on leveraging strategic partnerships and new technologies

Inherent in our growth strategy and our business model is our culture. It is a culture based on teamwork, continual improvement and long-term strategic thinking. Over the years, our culture and philosophy have enabled us to operate during periods of economic strength the same way we operate in a downturn. In fact, Nucor has a long history of taking advantage of economic downturns to grow stronger and expand our long-term earnings power. It is worth noting that a healthy portion of the profits realized over the past five years have been generated by assets we built or acquired during the last economic downturn experienced during the 2001 to 2003 time period. These highly successful growth initiatives included our entry into the plate market, and the acquisitions of Auburn Steel, Birmingham Steel and Trico Steel.

While the current economic downturn presents a number of risks to Nucor and the steel industry, we also believe that such an environment will present unusually attractive growth opportunities to a company that is in Nucor’s position of strength. We believe our strong balance sheet and disciplined approach will enable us to capitalize on these opportunities and continue to build Nucor into a better and more profitable company well into the future.

Optimization of existing operations

Nucor emphasizes optimizing existing operations in order to keep them state-of-the-art and globally competitive. Capital expenditures are currently projected to be approximately $400 million in 2009, a decrease of

4

Item 1. Business, continued

approximately 61% from 2008. This decrease is in part due to the substantial completion of several of our greenfield projects and also reflects the weakened business conditions resulting from the U.S. financial crisis of late 2008. The majority of the projected capital expenditures for 2009 will be used to maintain the productivity and efficiency of our existing facilities.

Greenfield growth

We continue to increase our presence in the steel mills segment through greenfield projects such as our special bar quality (“SBQ”) mill in Memphis, Tennessee, which has an estimated annual capacity of 850,000 tons. Complementing our mills in South Carolina and Nebraska, the Memphis mill positions Nucor to provide the most diverse, highest quality and lowest cost SBQ offering in North America. Production start-up began in the second half of 2008.

Another greenfield project is the Castrip^® facility under construction in Blytheville, Arkansas. Nucor began operations of its 100% owned Castrip facility in Crawfordsville, Indiana, in 2002. This facility uses the breakthrough technology of strip casting, to which Nucor holds exclusive rights in the United States and Brazil. Strip casting involves the direct casting of molten steel into final shape and thickness without further hot or cold rolling, allowing lower investment and operating costs, reduced energy consumption and smaller scale plants than can be economically built with current technology. This process also reduces the overall environmental impact of producing steel by generating significantly lower emissions. The Arkansas Castrip facility is expected to begin operating in the first half of 2009. We continue to explore potential new joint ventures utilizing the Castrip technology.

In 2008, we announced the opening of the previously idle Kingman, Arizona, rolling mill that we acquired in 2003, with operations ready to begin in the second quarter of 2009 subject to market conditions at that time. During the year, we substantially completed the construction of a galvanizing facility at our sheet mill in Decatur, Alabama, and commenced operations at our building systems plant in Brigham City, Utah. Nucor has also announced plans to install a plate heat treating facility at our plate mill in Hertford County, North Carolina. The heat treat line will have an estimated annual capacity of 120,000 tons and will have the ability to produce heat treated plate from 3/16 “through 2” thick. Production start-up is expected to begin in the second half of 2010.

In May 2008, Nucor applied for a permit to build a state-of-the-art iron-making facility in St. James Parish, Louisiana. Sites outside of the United States are still being considered, and the site selection and capital investment are subject to approval by Nucor’s board of directors. When completed, the first phase of the facility is expected to produce three million tons of pig iron, employing the latest technologies to reduce emissions. If the project is ultimately built in the U.S., it would be the first domestic greenfield pig iron facility built in more than 30 years.

Acquisitions

Nucor’s acquisitions over the past few years have strengthened our position as North America’s most diversified producer of steel and steel products. This diversity has been a significant factor in Nucor’s increased profitability and added market share across multiple product categories.

The annual capacity of Nucor’s downstream value-added products has more than doubled since late 2006 to over 4.5 million tons. We have done this with our very successful acquisitions of Verco Manufacturing Company in steel decking; Harris Steel Group Inc. in rebar fabrication, cold finished bars and metal grating; LMP Steel & Wire Company in cold finished bars; Magnatrax Corporation in metal buildings; and Nelson Steel, Inc. in wire mesh. Harris Steel continued to be a growth platform for Nucor in 2008, having completed numerous acquisitions in the months following Nucor’s initial acquisition in 2007. With the acquisition of Ambassador Steel, Inc. in 2008, Harris increased our rebar fabrication capacity to over 1.5 million tons.

5

Item 1. Business, continued

In February 2008, Nucor announced the acquisition of SHV North America Corporation, which owns 100% of DJJ and certain affiliates. Since scrap is our largest single cost, this strategic investment provides an ideal growth platform for Nucor to expand its direct ownership in the steel scrap supply chain and further our raw materials strategy. By the end of 2008, Nucor added approximately one million tons of scrap processing and 23 locations via four scrap processing acquisitions executed by DJJ’s management team. Nucor’s total scrap processing capacity is now approaching five million tons. Additionally, DJJ brokers ferrous scrap, ferro-alloys and non-ferrous metals and internationally sources scrap, pig iron, and scrap substitutes. The DJJ Mill and Industrial Services business provides logistics and metallurgical blending operations and offers on-site handling and trading of industrial scrap. The DJJ Rail Services business oversees a large private fleet of rail cars dedicated to scrap movement and offers complete railcar fleet management and leases for third parties. All of these businesses have strategic value to Nucor as the most diversified North American steel producer.

International growth

In 2008, Nucor established an international growth platform by opening a European office and executing a joint-venture investment with Duferco S. A. In July 2008, Nucor acquired 50% of the stock of Duferdofin—Nucor S.r.l. Duferdofin—Nucor operates a steel melting and bloom/billet caster in San Zeno, Italy as well as rolling mills in Pallanzeno in the Piedmont region and Giammoro in Sicily. A new merchant bar mill is under construction at the Giammoro plant and is expected to be fully operational by mid-2009. The new mill at the Giammoro plant is expected to produce approximately 450,000 metric tons. The new company also includes the distribution companies of the former Duferdofin, enabling Duferdofin—Nucor to supply steel across Southern Europe and North Africa.

Employees

Nucor has a simple, streamlined organizational structure to allow our employees to make quick decisions and be innovative. Our organization is highly decentralized, with most day-to-day operating decisions made by our division general managers and their staff. Only 85 employees are located in our executive offices. The majority of Nucor’s 21,700 employees are not represented by labor unions.

Item 1A. Risk Factors

Many of the factors that affect our business and operations involve risk and uncertainty. The factors described below are some of the risks that could materially negatively affect our business, financial condition and results of operations.

6

Item 1A. Risk Factors, continued

The current global recession and credit crisis have and are likely to continue to adversely affect our business.

The current deep and potentially prolonged global recession that officially began in the United States in December 2007 has, since the beginning of the third quarter of 2008, had a material adverse effect on demand for our products and consequently the results of our operations, financial condition and cash flows. In mid-February 2009, The Federal Reserve warned that the United States economy faces an “unusually gradual and prolonged” period of recovery from this deep and recessionary period.

The financial and credit crisis that intensified the current recession also triggered a period of upheaval characterized by bankruptcy, failure, collapse or sale at nominal amounts of various financial institutions. Despite the unprecedented level of intervention in the credit markets by the U.S. and foreign governments that has already occurred and is likely to continue to occur, this crisis could temporarily restrict our ability to borrow money on acceptable terms in the credit markets and potentially could affect our ability to draw on our credit facility. The financial and credit crisis is also making in difficult or, in many cases, impossible for our customers to borrow money to fund their operations. Their lack of or limited access to capital adversely affects their ability to purchase our products or, in some cases, to pay for our products on a timely basis.

Our industry is cyclical and prolonged economic declines could have a material adverse effect on our business.

Demand for most of our products is cyclical in nature and sensitive to general economic conditions. Our business supports cyclical industries such as the commercial construction, energy, appliance and automotive industries. As a result, downturns in the United States economy or any of these industries could materially adversely affect our results of operations and cash flows. Because steel producers generally have high fixed costs, reduced volumes result in operating inefficiencies. Over the six-year period ended December 31, 2008, our net earnings have varied from a record high of $1.83 billion in 2008 to a low of $64.8 million in 2003. Future economic downturns or a prolonged stagnant economy could materially adversely affect our business, results of operations, financial condition and cash flows.

Overcapacity in the global steel industry could increase the level of steel imports, which may negatively affect our business, results of operations and cash flows.

Global steel-making capacity exceeds global consumption of steel products, particularly during periods of global recession. This excess capacity results in manufacturers in certain countries exporting significant amounts of steel and steel products at prices below their cost of production. These imports, which are also affected by demand in the domestic market, international currency conversion rates and domestic and international government actions, can result in downward pressure on steel prices, which could materially adversely affect our business, results of operations, financial condition and cash flows.

Overcapacity in China, the world’s largest producer and consumer of steel, has the potential to result in a further increase in imports of low-priced, unfairly traded steel and steel products to the United States. In recent years, capacity growth in China has significantly exceeded the growth in Chinese market demand. A continuation of this unbalanced growth trend or a significant decrease in China’s rate of economic expansion could result in China increasing steel exports.

The results of our operations are sensitive to volatility in steel prices and changes in the cost of raw materials, particularly scrap steel.

We rely to an extent on outside vendors to supply us with raw materials, including both scrap and scrap substitutes, that are critical to the manufacture of our products. Although Nucor has vertically integrated its business through the successful start-up of our DRI facility in Trinidad and through the acquisition of DJJ, we may still be required to purchase our primary raw material, steel scrap, from numerous other sources throughout

7

Item 1. Risk Factors, continued

the country. Although we believe that the supply of scrap is adequate to operate our facilities, purchase prices of these critical raw materials are subject to volatility and are influenced by changes in scrap exports in response to changes in the scrap demands of global competitors. At any given time, we may be unable to obtain an adequate supply of these critical raw materials with price and other terms acceptable to us. The availability and prices of raw materials may also be negatively affected by new laws and regulations, allocation by suppliers, interruptions in production, accidents or natural disasters, changes in exchange rates, worldwide price fluctuations, and the availability and cost of transportation.

If our suppliers increase the prices of our critical raw materials, we may not have alternative sources of supply. In addition, to the extent that we have quoted prices to our customers and accepted customer orders for our products prior to purchasing necessary raw materials, we may be unable to raise the price of our products to cover all or part of the increased cost of the raw materials, although we have successfully used a raw material surcharge in the steel mills segment since 2004. Also, if we are unable to obtain adequate and timely deliveries of our required raw materials, we may be unable to timely manufacture sufficient quantities of our products. This could cause us to lose sales, incur additional costs and suffer harm to our reputation.

Changes in the availability and cost of electricity and natural gas are subject to volatile market conditions that could adversely affect our business.

Our steel mills are large consumers of electricity and natural gas. We rely upon third parties for our supply of energy resources consumed in the manufacture of our products. The prices for and availability of electricity, natural gas, oil and other energy resources are subject to volatile market conditions. These market conditions often are affected by weather and political and economic factors beyond our control. Disruptions in the supply of our energy resources could temporarily impair our ability to manufacture our products for our customers. Increases in our energy costs could materially adversely affect our business, results of operations, financial condition and cash flows.

Our steel making processes, and the manufacturing processes of many of our customers and suppliers, are energy intensive and generate carbon dioxide and other “Greenhouse Gasses” (GHG’s).

In 2008, several bills were introduced but not passed in the United States Senate that would regulate GHG and carbon dioxide emissions. Similar bills will be introduced in 2009. This legislation, when adopted, will increase our energy and other operating costs. This proposed legislation regulates domestic production but excludes imports from the same standards for a period of eight years, which will make domestic manufacturing uncompetitive with imported products during this time. These increased costs could also encourage more of our customers to relocate their manufacturing facilities to foreign countries that do not regulate GHG emissions and where Nucor is not positioned to sell or distribute our products. This proposed legislation is also likely to increase energy costs for all U.S. consumers resulting in a weaker domestic economy.

We plan to continue to implement our acquisition strategy and may encounter difficulties in integrating businesses we acquire.

We plan to continue to seek attractive opportunities to acquire businesses, enter into joint ventures and make other investments that are complementary to our existing strengths. Realizing the anticipated benefits of acquisitions or other transactions will depend on our ability to operate these businesses and integrate them with our operations and to cooperate with our strategic partners. Our business, results of operations, financial condition and cash flows could be materially and adversely affected if we are unable to successfully integrate these businesses.

In addition, we may enter into joint ventures or acquisitions located outside the U.S., which may be adversely affected by foreign currency fluctuations, changes in economic conditions and changes in local government regulations and policies.

Item 1. Risk Factors, continued

Competition from other materials may have a material adverse effect our business.

In many applications, steel competes with other materials, such as aluminum, cement, composites, glass, plastic and wood. Increased use of these materials in substitution for steel products could have a material adverse effect on prices and demand for our steel products.

Congress has raised the Corporate Average Fuel Economy (“CAFE”) mileage requirements for new cars and light trucks produced beginning in 2011. Automobile producers may reduce the steel content of cars and trucks to achieve the new CAFE fuel economy standards, reducing demand for steel and resulting in an over-supply in North America.

Our operations are subject to business interruptions and casualty losses.

The steel-making business is subject to numerous inherent risks, particularly unplanned events such as explosions, fires, other accidents, inclement weather and transportation interruptions. While our insurance coverage could offset losses relating to some of those types of events, our results of operations and cash flows could be adversely impacted to the extent any such losses are not covered by our insurance.

Our business requires substantial capital investment and maintenance expenditures, and our capital resources may not be adequate to provide for all of our cash requirements.

Our operations are capital intensive. For the five-year period ended December 31, 2008, our total capital expenditures, excluding acquisitions, were approximately $2.50 billion. Our business also requires substantial expenditures for routine maintenance. Although we expect requirements for our business needs, including the funding of capital expenditures, debt service for financings and any contingencies to be financed by internally generated funds or from borrowings under our $1.3 billion unsecured revolving credit facility, we cannot assure you that this will be the case. Additional acquisitions could require financing from external sources.

Environmental compliance and remediation could result in substantially increased costs and materially adversely impact our competitive position.

Our operations are subject to numerous federal, state and local laws and regulations relating to protection of the environment, and we, accordingly, make provision in our financial statements for the estimated costs of compliance. These laws are becoming increasingly stringent, resulting in inherent uncertainties in these estimates. To the extent that competitors, particularly foreign steel producers and manufacturers of competitive steel products, are not required to incur equivalent costs, our competitive position could be materially adversely impacted.

Changes in foreign currency may adversely affect our financial results.

Some of our steel products and other subsidiaries conduct their business in local currency and, for purposes of financial reporting, their results are translated into U.S. dollars based on average exchange rates prevailing during a reporting period. During times of a strengthening U.S. dollar, our reported net revenues and operating income will be reduced because the local currency will translate to fewer U.S. dollars.

The accounting treatment of goodwill and other intangible assets could result in future asset impairments, which would reduce our earnings.

We periodically calculate the fair value of our goodwill and intangible assets to test for impairment. The results of this calculation may be affected by the current adverse market conditions for the steel industry, as well as interest rates and general economic conditions. If impairment is determined to exist, we will incur impairment losses, which will reduce our earnings.

Item 2. Properties, continued

quarter of 2008, the average utilization rates of all operating facilities in the steel mills, steel products and raw materials segments were approximately 48%, 63% and 45% of production capacity. The utilization decrease in the fourth quarter was due to slowing production needed to meet declining demand for our products.

We also own our principal executive office in Charlotte, North Carolina.

Item 3. Legal Proceedings

Nucor has been named, along with other major steel producers, as a co-defendant in several related antitrust class-action complaints filed by Standard Iron Works and other steel purchasers in the United States District Court for the Northern District of Illinois. The cases are filed as class actions. The plaintiffs allege that from January 2005 to the present eight steel manufacturers, including Nucor, engaged in anticompetitive activities with respect to the production and sale of steel. The plaintiffs seek monetary and other relief. Although we believe the plaintiffs’ claims are without merit and will vigorously defend against them, we cannot at this time predict the outcome of this litigation or determine Nucor’s potential exposure.

Nucor is involved in various other judicial and administrative proceedings as both plaintiff and defendant, arising in the ordinary course of business. Nucor does not believe that any such proceedings (including matters relating to contracts, torts, taxes, warranties and insurance) will have a material adverse effect on its business, operating results, financial condition or cash flows.

Item 4. Submission of Matters to a Vote of Security Holders

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Nucor has increased its base cash dividend every year since the Company began paying dividends in 1973. In 2008, in addition to increasing the base dividend, the board of directors approved a supplemental dividend in each of the first three quarters based on Nucor’s strong performance during the year. As a result, Nucor paid a total dividend of $2.17 per share in 2008 compared with $2.43 per share in 2007. In February 2009, the board of directors declared Nucor’s 144th consecutive quarterly cash dividend of $0.35 per share payable on May 12, 2009 to stockholders of record on March 31, 2009.

Additional information regarding the market for Nucor’s common stock, quarterly market price ranges, the number of stockholders and dividend payments is incorporated by reference to Nucor’s 2008 Annual Report, page 62.

Item 6. Selected Financial Data

Historical financial information is incorporated by reference to Nucor’s 2008 Annual Report, page 33.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Information required by this item is incorporated by reference to Nucor’s 2008 Annual Report, page 2 (Forward-looking Statements) and pages 20 through 29.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

In the ordinary course of business, Nucor is exposed to a variety of market risks. We continually monitor these risks and develop appropriate strategies to manage them.

Interest Rate Risk—Nucor manages interest rate risk by using a combination of variable-rate and fixed-rate debt. At December 31, 2008, 14% of Nucor’s long-term debt was in industrial revenue bonds that have variable interest rates that are adjusted weekly or annually. The remaining 86% of Nucor’s debt is at fixed rates. Future changes in interest rates are not expected to significantly impact earnings. Nucor also makes use of interest rate swaps to manage net exposure to interest rate changes. As of December 31, 2008, there were no such contracts outstanding. Nucor’s investment practice is to invest in securities that are highly liquid with short maturities. As a result, we do not expect changes in interest rates to have a significant impact on the value of our investment securities.

Commodity Price Risk—In the ordinary course of business, Nucor is exposed to market risk for price fluctuations of raw materials and energy, principally scrap steel, other ferrous and nonferrous metals, alloys and natural gas. We attempt to negotiate the best prices for our raw materials and energy requirements and to obtain prices for our steel products that match market price movements in response to supply and demand. Nucor has a raw material surcharge designed to pass through the cost increases of scrap steel and other raw materials.

As a result of the rapid fall-off in sales due to weaker market conditions in the fourth quarter of 2008, we are beginning 2009 with high inventories of more expensive scrap and scrap substitutes. Since pig iron and certain grades of scrap have lead times of four to six months, dramatically reduced sales volumes resulted in the accumulation of increased tons of inventories ordered at peak market prices. If market conditions remain depressed for a prolonged period, it will take longer for us to work through these expensive raw materials (primarily pig iron at our sheet mills).

13

Item 7A. Quantitative and Qualitative Disclosures about Market Risk, continued

Nucor also uses derivative financial instruments to hedge a portion of our exposure to price risk related to natural gas purchases used in the production process and to hedge a portion of our aluminum and copper purchases and sales. Gains and losses from derivatives designated as hedges are deferred in accumulated other comprehensive income (loss) on the consolidated balance sheets and recognized into earnings in the same period as the underlying physical transaction. At December 31, 2008, accumulated other comprehensive income (loss) includes $66.0 million in unrealized net-of-tax losses for the fair value of these derivative instruments. Changes in the fair values of derivatives not designated as hedges are recognized in earnings each period. The following table presents the negative effect on pre-tax income of a hypothetical change in the fair value of derivative instruments outstanding at December 31, 2008, due to an assumed 10% and 25% change in the market price of each of the indicated commodities (in thousands):

Commodity Derivative	10% Change		25% Change
Natural gas	$	143,614	$	201,900
Aluminum		1,485		3,711
Copper		218		545

Any resulting changes in fair value would be recorded as adjustments to other comprehensive income (loss), net of tax, or recognized in net earnings, as appropriate. These hypothetical losses would be partially offset by the benefit of lower prices paid or higher prices received for the physical commodities.

Foreign Currency Risk—Nucor is exposed to foreign currency risk through its operations in Canada and Trinidad and its joint ventures in Australia and Italy. In the first half of 2008, the Company entered into forward foreign currency contracts in order to mitigate the risk of currency fluctuation on the anticipated joint venture with the Duferco Group of Lugano, Switzerland. These contracts had a notional value of €423.5 million and matured in the second quarter of 2008 resulting in gains of $17.6 million. These contracts all settled during the second quarter of 2008.
