Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited)

1. BASIS OF INTERIM PRESENTATION: The information furnished in Item I reflects all adjustments which are, in the opinion of management, necessary to a fair statement of the results for the interim periods and are of a normal and recurring nature. The information furnished has not been audited; however, the December 31, 2006 condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in Nucor’s annual report for the fiscal year ended December 31, 2006. Certain amounts for the prior year have been reclassified to conform to the 2007 presentation.

Effective January 1, 2007, Nucor adopted the Financial Accounting Standards Board (“FASB”) Staff Position AUG AIR-1, “Accounting for Planned Major Maintenance Activities.” This position statement eliminates Nucor’s previous policy to accrue in advance for planned major maintenance activities. In accordance with this position statement, Nucor now uses the deferral method of accounting for planned maintenance activities and has adjusted prior period financial statements to retrospectively apply this position statement. The effects of this adjustment on our 2006 financial statements are as follows (in thousands, except per share amounts):

	Consolidated Balance Sheet
	As of December 31, 2006
	As Previously Reported		Adjustments			As Adjusted
Other current assets	$	270,236	$	8,029		$	278,265
Accrued expenses and other current liabilities		478,337		(28,111	)		450,226
Minority interests		238,588		4,778			243,366
Retained earnings		5,808,705		31,362			5,840,067

	Consolidated Statements of Earnings
	Nine Months (39 Weeks) Ended September 30, 2006							Three Months (13 Weeks) Ended September 30, 2006
	As Previously Reported		Adjustments			As  Adjusted		As Previously Reported		Adjustments			As Adjusted
Cost of products sold	$	8,631,598	$	(2,850	)	$	8,628,748	$	2,926,581	$	(5,799	)	$	2,920,782
Minority interests		148,036		(468	)		147,568		59,104		(444	)		58,660
Earnings before income taxes		2,078,533		3,318			2,081,851		795,517		6,243			801,760
Provision for income taxes		729,011		1,162			730,173		277,939		2,185			280,124
Net earnings		1,349,522		2,156			1,351,678		517,578		4,058			521,636
Net earnings per share:
Basic		4.37		0.01			4.38		1.70		0.01			1.71
Diluted		4.33		0.01			4.34		1.68		0.01			1.70

The effect of the adjustment on the consolidated statement of cash flows was not significant.

Also effective January 1, 2007, Nucor adopted FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109,” which clarifies the accounting of uncertainty in income taxes recognized in financial statements in accordance with FASB Statement No. 109, “Accounting for Income Taxes” (see Note 14). FIN 48 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return.

2. ACQUISITIONS: Since 2004, Nucor has owned a one-half interest in the rebar fabricator Harris Steel Inc., the remaining one-half interest of which was owned by Harris Steel Group Inc. (“Harris Steel”). In March 2007, a wholly owned subsidiary of Nucor acquired all the issued and outstanding shares of Harris Steel for a cash purchase price of Cdn$46.25 per Harris Steel share. The purchase price includes approximately $1.06 billion paid in cash and $68.4 million of short-term debt assumed related to the net assets acquired. Nucor also consolidated an additional $18.2 million of short-term debt related to its previous 50% ownership in Harris Steel Inc. As a result of the acquisition, Nucor has consolidated Harris Steel Inc. which was previously accounted for under the equity method. Harris Steel, which now operates as a subsidiary of Nucor, manufactures industrial products principally in the U.S. and Canada. Harris Steel also participates in steel trading on a worldwide basis and distributes reinforcing steel and related products to U.S. customers.

We have obtained preliminary independent appraisals for the purpose of allocating the purchase price to the individual assets acquired and liabilities assumed. These valuations are subject to adjustment as additional information is obtained; however, these adjustments are not expected to be material. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed of Harris Steel as of the date of acquisition (in thousands):

Current assets	$	460,037
Property, plant and equipment		122,187
Goodwill		478,337
Other intangible assets		305,217
Other assets		565
Total assets acquired		1,366,343
Short-term debt		(68,365	)
Other current liabilities		(108,906	)
Deferred credits and other liabilities		(126,098	)
Minority interests		(3,522	)
Total liabilities assumed		(306,891	)
Net assets acquired	$	1,059,452

The preliminary purchase price allocation to the identifiable intangible assets is as follows (in thousands, except years):

			Weighted Average Life
Customer relationships	$	271,462		22 years
Trade names		33,755		20 years
	$	305,217		22 years

The majority of the goodwill has been preliminarily allocated to the steel products segment (see Note 6).

Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited), continued

The results of Harris Steel have been included in the consolidated financial statements from the date of acquisition. Unaudited pro forma operating results for Nucor, assuming the acquisition of Harris Steel occurred at the beginning of each period are as follows (in thousands, except per share data):

	Nine Months (39 Weeks) Ended				Three Months (13 Weeks) Ended
	September 29, 2007		September 30, 2006		September 29, 2007		September 30, 2006
Net sales	$	12,372,841	$	12,143,084	$	4,259,221	$	4,248,248
Net earnings		1,115,751		1,399,443		381,222		551,616
Net earnings per share:
Basic	$	3.74	$	4.54	$	1.30	$	1.81
Diluted	$	3.71	$	4.49	$	1.29	$	1.79

In June 2007, Harris Steel Inc. purchased the stock of South Pacific Steel Corp., a rebar fabricator and installer, for a cash purchase price of approximately $24.9 million. In addition, in August 2007, Harris Steel acquired Consolidated Rebar, Inc. for a cash purchase price of approximately $23.3 million. Consolidated has two rebar fabrication facilities in Arizona.

In August 2007, Nucor purchased substantially all the assets of LMP Steel & Wire Company (“LMP”) for a cash purchase price of approximately $27.2 million. Located in Maryville, Missouri, LMP is a producer of cold finished bar.

Also in August 2007, a wholly owned subsidiary of Nucor merged with Magnatrax Corporation ("Magnatrax"), a leading provider of custom-engineered metal building systems with seven fabricating plants located across the United States. The cash purchase price of $275.2 million includes approximately $158.7 million of goodwill that has been allocated to the steel products segment. The cash purchase price also includes $116.2 million of identifiable intangibles, primarily related to customer relationships which are being amortized over 21 years.

In May 2006, Nucor’s wholly owned subsidiary, Nucor Steel Connecticut, Inc., purchased substantially all of the assets of Connecticut Steel Corporation for a cash purchase price of approximately $43.9 million. This facility produces wire rod, rebar, wire mesh and structural mesh.

3. SHORT-TERM INVESTMENTS: As of December 31, 2006, short-term investments consisted entirely of variable rate demand notes (“VRDN’s”), which are variable rate bonds tied to short-term interest rates with maturities on the face of the securities in excess of 90 days. All VRDN’s were liquidated during the third quarter of 2007. All of the VRDN’s in which Nucor invests are secured by a direct-pay letter of credit issued by a high-credit quality financial institution. Nucor is able to receive the principal invested and interest accrued thereon no later than seven days after notifying the financial institution that Nucor has elected to tender the VRDN’s. Since VRDN’s trade at par value, no realized or unrealized gains or losses were incurred.

Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited), continued

4. INVENTORIES: Inventories consist of approximately 43% raw materials and supplies and 57% finished and semi-finished products at September 29, 2007 (48% and 52% respectively, at December 31, 2006). Nucor’s manufacturing process consists of a continuous, vertically integrated process from which products are sold to customers at various stages. Since most steel products can be classified as either finished or semi-finished products, these two categories of inventory are combined.

Inventories valued using the last-in, first-out (LIFO) method of accounting represent approximately 51% of total inventories as of September 29, 2007 (63% of total inventories as of December 31, 2006). If the first-in, first-out (FIFO) method of accounting had been used, inventories would have been $489.2 millionhigher at September 29, 2007 ($387.2 million higher at December 31, 2006).

5. PROPERTY, PLANT AND EQUIPMENT: Property, plant and equipment is recorded net of accumulated depreciation of $3.83 billion at September 29, 2007 ($3.54 billion at December 31, 2006).

6. GOODWILL AND OTHER INTANGIBLE ASSETS: The change in the net carrying amount of goodwill for the nine months ended September 29, 2007 by segment is as follows (in thousands):

	Steel Mills		Steel Products			Total
Balance at December 31, 2006	$	2,007	$	141,258		$	143,265
Acquisitions		-		639,133			639,133
Purchase price adjustments		-		(15,740	)		(15,740	)
Translation		-		45,562			45,562
Balance at September 29, 2007	$	2,007	$	810,213		$	812,220

Goodwill resulting from the acquisition of Harris Steel and Magnatrax accounts for almost all of the increase in goodwill in the first nine months of 2007 and is presented based upon Nucor’s preliminary purchase price allocation. The majority of goodwill is not tax deductible.

Intangible assets with estimated lives of five to 22 years are amortized on a straight-line or accelerated basis and are comprised of the following (in thousands):

	September 29, 2007				December 31, 2006
	Gross Amount		Accumulated Amortization		Gross Amount		Accumulated Amortization
Customer relationships	$	414,320	$	12,658	$	-	$	-
Trademarks and trade names		52,686		1,051
Other		24,102		5,455		8,742		3,727
	$	491,108	$	19,164	$	8,742	$	3,727

Intangible asset amortization expense was $15.4 million and $1.0 million in the first nine months of 2007 and 2006, respectively, and was $8.3 million and $0.3 million in the third quarter of 2007 and 2006, respectively. Annual amortization expense is estimated to be $23.6 million in 2007; $40.8 million in 2008; $38.2 million in 2009; $35.8 million in 2010; and $32.8 million in 2011.

Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited), continued

7. CURRENT LIABILITIES: Drafts payable and book overdrafts, included in accounts payable in the balance sheet, were $85.3 million at September 29, 2007 ($74.7 million at December 31, 2006).

Dividends payable, included in accrued expenses and other current liabilities in the balance sheet, was $176.5 million at September 29, 2007 ($181.2 million at December 31, 2006).

8. DEBT AND OTHER FINANCING ARRANGEMENTS: In addition to Nucor’s $700 million five-year unsecured revolving credit facility maturing in June 2010, Harris Steel has credit facilities with a Canadian bank totaling approximately $55.0 million. No borrowings were outstanding at September 29, 2007 under either facility.

In addition, the business of Novosteel, of which Harris Steel owns 75%, is financed by trade credit arrangements totaling approximately $197.5 million with a number of Swiss-based banking institutions. These arrangements, principally letters of credit under trade finance facilities, are non-recourse to Nucor and its other subsidiaries. As of September 29, 2007, there were outstanding borrowings of $22.3 million and outstanding letters of credit of $15.2 million under the Swiss trade credit arrangements for commitments to purchase inventories, which had not yet been received.

9. STOCK-BASED COMPENSATION: Stock Options - Nucor’s stock option plans provide that common stock options may be granted to key employees, officers and non-employee directors with exercise prices at 100% of the market price on the date of the grant. Outstanding options are exercisable six months after the grant date and have a term of seven years. Nucor did not grant any options during 2006 or during the nine months ended September 29, 2007 and does not expect to grant options to its employees, officers or non-employee directors in future periods. A summary of activity under Nucor’s stock option plans for the nine months ended September 29, 2007 is as follows (in thousands, except year and per share amounts):

	Shares			Weighted Average Exercise Price		Weighted Average Remaing Contractual Life		Aggregate Intrinsic Value
Number of shares under option:
Outstanding at beginning of year		2,461		$	20.21
Exercised		(547	)		19.28			$	24,556
Canceled		-			-
Outstanding at September 29, 2007		1,914		$	20.47		3.5 years	$	74,656
Options exercisable at September 29, 2007		1,914		$	20.47		3.5 years	$	74,656

As of March 1, 2006 all outstanding options were vested; therefore, no compensation expense related to stock options was recorded in the first nine months of 2007 ($2.5 million in the first nine months of 2006 and none in the third quarter of 2006). The amount of cash received from the exercise of stock options totaled $10.4 million and $0.5 million in the first nine months and third quarter of 2007, respectively.

Restricted Stock Awards - Nucor’s Senior Officers Annual Incentive Plan (the “AIP”) and Long-Term Incentive Plan (the “LTIP”) authorize the award of shares of common stock to officers subject to certain conditions and restrictions. The LTIP provides for the award of shares of restricted common stock at the end of each LTIP performance measurement period at no cost to officers if certain financial performance goals are met during the period. One-third of the LTIP restricted stock award vests upon each of the first three anniversaries of the award date or, if earlier, upon the officer’s attainment of age fifty-five while employed by Nucor. Although participants are entitled to cash dividends and may vote such awarded shares, the sale or transfer of such shares is limited during the restricted period.

10

Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited), continued

The AIP provides for the payment of annual cash incentive awards. An AIP participant may elect, however, to defer payment of up to one-half of an annual incentive award. In such event, the deferred AIP award is converted into common stock units and credited with a deferral incentive, in the form of additional common stock units, equal to 25% of the number of common stock units attributable to the deferred AIP award. Common stock units attributable to deferred AIP awards are fully vested. Common stock units credited as a deferral incentive vest upon the AIP participant’s attainment of age fifty-five while employed by Nucor. Vested common stock units are paid to AIP participants in the form of shares of common stock following their termination of employment with Nucor.

A summary of Nucor’s restricted stock activity under the AIP and LTIP for the first nine months of 2007 is as follows (shares in thousands):

	Shares			Weighted Average Price
Restricted stock awards and units:
Unvested at beginning of year		553		$	39.14
Granted		464			64.26
Vested		(488	)		49.24
Canceled		-			-
Unvested at September 29, 2007		529		$	51.87
Shares reserved for future grants		2,267

Compensation expense for common stock and common stock units awarded under the AIP and LTIP is recorded over the performance measurement and vesting periods based on the anticipated number and market value of shares of common stock and common stock units to be awarded. Compensation expense for anticipated awards based upon Nucor’s financial performance, exclusive of amounts payable in cash, was $13.8 million and $16.0 million in the first nine months of 2007 and 2006, respectively, and was $4.8 million and $4.2 million in the third quarter of 2007 and 2006, respectively. At September 29, 2007, unrecognized compensation expense related to unvested restricted stock was $6.7 million, which is expected to be recognized over a weighted-average period of 1.8 years.

Restricted Stock Units: In June 2006, Nucor granted restricted stock units (“RSU’s”) to key employees, officers and non-employee directors for the first time. The RSU’s typically vest and are converted to common stock in three equal installments on each of the first three anniversaries of the grant date. A portion of the RSU’s awarded to senior officers vest upon the officer’s retirement. Retirement, for purposes of vesting in these units only, means termination of employment with approval of the Compensation and Executive Development Committee after satisfying age and years of service requirements. RSU’s granted to non-employee directors are fully vested on the grant date and are payable to the non-employee director in the form of common stock after the termination of the director’s service on the board of directors.

Nucor Corporation - Notes to Condensed Consolidated Financial Statements (Unaudited), continued

RSU’s granted to employees who are eligible for retirement on the date of grant or will become retirement-eligible prior to the end of the vesting term are expensed over the period through which the employee will become retirement-eligible since the awards vest upon retirement from the Company. Compensation expense for RSU’s granted to employees who are not retirement-eligible is recognized on a straight-line basis over the vesting period. Cash dividend equivalents are paid to participants each quarter. Dividend equivalents paid on units expected to vest are recognized as a reduction in retained earnings.

The fair value of the RSU’s is determined based on the closing stock price of Nucor’s common stock on the day before the grant. A summary of Nucor’s restricted stock unit activity for the first nine months of 2007 is as follows (shares in thousands):

	Shares			Weighted Average Price
Restricted stock awards and units:
Unvested at beginning of year		597		$	52.64
Granted		637			67.54
Vested		(294	)		58.89
Canceled		(5	)		57.38
Unvested at September 29, 2007		935		$	60.79
Shares reserved for future grants		17,682

Compensation expense for RSU’s was $20.1 million and $11.7 million in the first nine months of 2007 and 2006, respectively, and was $5.7 million and $6.5 million in the third quarter of 2007 and 2006, respectively. As of September 29, 2007, there was $46.1 million of total unrecognized compensation cost related to nonvested RSU’s, which is expected to be recognized over a weighted-average period of 2.0 years.

10.DERIVATIVES: Nucor utilizes forward foreign exchange contracts to hedge cash flows associated with certain assets and liabilities, firm commitments and anticipated transactions. These instruments are measured at their fair value with any foreign exchange gain/loss recorded in the same line as the underlying transactions (cost of products sold or marketing, administrative and other expenses) if they do not meet hedge accounting criteria. Derivatives meeting hedging requirements are also measured at fair value; however, any unrealized gains or losses are recorded as accumulated other comprehensive income until final settlement, at which time the gains/losses are recorded in the same line as the underlying transactions.

In January 2007, the Company entered into forward foreign currency contracts in order to mitigate the risk of currency fluctuation on the fixed purchase price for the acquisition of Harris Steel, which closed in March 2007. These contracts had a notional value of Cdn$600 million and settled in March 2007 resulting in a recognized gain of $5.8 million included in marketing, administrative and other expenses in the first quarter.

11.CONTINGENCIES: Nucor is subject to environmental laws and regulations established by federal, state and local authorities and makes provision for the estimated costs related to compliance. Of the undiscounted total of $20.4 million of accrued environmental costs at September 29, 2007 ($23.0 million at December 31, 2006), $17.1 million was classified in accrued expenses and other current liabilities ($19.7 million at December 31, 2006) and $3.3 million was classified in deferred credits and other liabilities ($3.3 million at December 31, 2006).

12

Nucor Corporation – Notes to Condensed Consolidated Financial Statements (Unaudited), continued

Other contingent liabilities with respect to product warranties, legal proceedings and other matters arise in the normal course of business. In the opinion of management, no such matters exist which would have a material effect on the consolidated financial statements.

12.  EMPLOYEE BENEFIT PLAN: Nucor has a Profit Sharing and Retirement Savings Plan for qualified employees. Nucor’s expense for these benefits was $175.9 million and $213.0 million in the first nine months of 2007 and 2006, respectively, and was $58.9 million and $80.2 million in the third quarter of 2007 and 2006, respectively.

13.  INTEREST (INCOME) EXPENSE: The components of net interest (income) expense are as follows (in thousands):

	Nine Months (39 Weeks) Ended						Three Months (13 Weeks) Ended
	Sept. 29, 2007			Sept. 30, 2006			Sept. 29, 2007			Sept. 30, 2006
Interest income	$	(37,302	)	$	(55,849	)	$	(6,876	)	$	(20,599	)
Interest expense		36,695			30,096			10,452			10,166
Interest (income) expense, net	$	(607	)	$	(25,753	)	$	3,576		$	(10,433	)

14.  INCOME TAXES: Nucor adopted the provisions of FIN 48 on January 1, 2007. As a result of the implementation of FIN 48, Nucor recognized a $31.1 million decrease to reserves for uncertain tax positions. At the adoption date, Nucor had approximately $92.4 million of unrecognized tax benefits, of which $90.2 million would affect Nucor’s effective tax rate, if recognized. At September 29, 2007, Nucor had approximately $89.4 million of unrecognized tax benefits. It is expected that the amount of unrecognized tax benefits will change in the next 12 months. However, we do not expect the change to have a significant impact on our results of operations or financial position.

Nucor recognizes interest and penalties accrued related to unrecognized tax benefits as a component of income before taxes, which is consistent with the recognition of these items in prior reporting periods. As of September 29, 2007, Nucor had approximately $33.3 million of accrued interest and penalties related to uncertain tax positions.

The Internal Revenue Service (“IRS”) is currently examining Nucor’s 2005 federal income tax returns. Management believes that the Company has adequately provided for any adjustments that may arise from this audit. Nucor has substantially concluded U.S. federal income tax matters for years through 2004. The 2006 tax year is open to examination by the IRS. The tax years 2003 through 2006 remain open to examination by other major taxing jurisdictions to which Nucor is subject.

15.  COMPREHENSIVE INCOME: Total comprehensive income is composed primarily of net earnings, net unrealized gains and losses on cash flow hedges and foreign currency translation adjustments. Total comprehensive income was $1.24 billion and $1.31 billion in the first nine months of 2007 and 2006, respectively ($473.9 million and $503.5 million in the third quarter of 2007 and 2006, respectively).

16. SEGMENTS: Nucor reports its results in the following segments: steel mills and steel products. The steel mills segment includes carbon and alloy steel in sheet, bars, structural and plate. The steel products segment includes 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 segments are consistent with the way Nucor manages its business, which is primarily based upon the similarity of the types of products produced and sold by each segment.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Certain statements made in this quarterly report are forward-looking statements that involve risks and uncertainties. These forward-looking statements reflect the Company’s best judgment based on current information, and although we base these statements on circumstances that we believe to be reasonable when made, there can be no assurance that future events will not affect the accuracy of such forward-looking information. As such, the forward-looking statements are not guarantees of future performance, and actual results may vary materially from the results and expectations discussed in this report. Factors that might cause the Company’s actual results to differ materially from those anticipated in forward-looking statements include, but are not limited to: (1) the sensitivity of the results of our operations to prevailing steel prices and the changes in the supply and cost of raw materials, including scrap steel; (2) availability and cost of electricity and natural gas; (3) market demand for steel products; (4) competitive pressure on sales and pricing, including pressure from imports and substitute materials; (5) uncertainties surrounding the global economy, including excess world capacity for steel production and fluctuations in international conversion rates; (6) U.S. and foreign trade policy affecting steel imports or exports; (7) significant changes in government regulations affecting environmental compliance; (8) the cyclical nature of the steel industry; (9) capital investments and their impact on our performance; and (10) our safety performance.

The following discussion should be read in conjunction with the unaudited condensed consolidated financial statements included elsewhere in this report, as well as the audited consolidated financial statements and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Nucor’s Annual Report on Form 10-K for the year ended December 31, 2006.

Overview

Nucor and affiliates are manufacturers of steel products, with operating facilities primarily in the U.S. and Canada. Products produced include: carbon and alloy steel - in bars, beams, sheet and plate; 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. Nucor is the nation's largest recycler.

In March 2007, a wholly owned subsidiary of Nucor acquired all the issued and outstanding shares of Harris Steel Group Inc. ("Harris Steel") for a cash purchase price of approximately $1.06 billion and $68.4 million of assumed short-term debt. Harris Steel has several business units: Harris Rebar, which is involved in the fabrication and placing of concrete reinforcing steel and the design and installation of concrete post-tensioning systems; Laurel Steel, which is a manufacturer and distributor of wire and wire products, welded wire mesh and cold finished bar; and Fisher & Ludlow, which is a manufacturer and distributor of heavy industrial steel grating, aluminum grating and expanded metal. These operations serve customers throughout Canada and the United States. Harris Steel also participates in steel trading on a worldwide basis through Novosteel (owned 75% by Harris Steel), and distributes reinforcing steel and related products to customers in the United States through Harris Supply Solutions. Harris Steel employs approximately 3,000 people throughout its organization. The results of Harris Steel are included in the Company’s results of operations as of the date of acquisition.

During the second and third quarters of 2007, Nucor acquired four downstream companies for a combined cash purchase price of approximately $350.6 million: Magnatrax Corporation, LMP Steel & Wire, South Pacific Steel Corp. and Consolidated Rebar, Inc. These acquisitions enhance Nucor’s product diversification and are part of the execution of Nucor’s strategy for profitable downstream growth.

Operations

Net sales for the first nine months of 2007 increased 8% to $12.20 billion, compared with $11.28 billion in last year’s first nine months. Average sales price per ton increased 8% from $662 in the first nine months of 2006 to $716 in the first nine months of 2007, while total tons shipped to outside customers remained flat compared to the first nine months of 2006. Net sales for the third quarter of 2007 increased 8% to $4.26 billion, compared with $3.93 billion in the third quarter of 2006. The increase was due to a 5% increase in average sales price per ton from $702 in the third quarter of 2006 to $738 in the third quarter of 2007, accompanied by a 3% increase in total tons shipped to outside customers. Average sales price per ton decreased 1% from the second quarter of 2007 to the third quarter of 2007, while total tons shipped to outside customers increased 3%.

Management’s Discussion and Analysis of Financial Condition and Results of Operations, continued

Steel production was 16,503,000 tons in the first nine months of 2007, compared with 17,318,000 tons produced in the first nine months of 2006, a decrease of 5%. Total steel shipments decreased 4% to 16,663,000 tons in the first nine months of 2007, compared with 17,286,000 tons in last year’s first nine months. Steel sales to outside customers decreased 5% to 15,157,000 tons in the first nine months of 2007, compared with 15,936,000 tons in last year’s first nine months. In the steel products segment, steel joist production during the first nine months was 409,000 tons, compared with 433,000 tons in the first nine months of 2006, a decrease of 6%. Steel deck sales increased to 355,000 tons in the first nine months of 2007, compared with 284,000 tons in last year's first nine months. Cold finished steel sales increased 23% to 322,000 tons in the first nine months of 2007 compared with 261,000 tons in the first nine months of 2006. With the acquisition of Harris Steel at the end of the first quarter, sales of fabricated concrete reinforcing steel were 385,000 tons in the first nine months of 2007. The average estimated utilization rates of all operating facilities in the steel mills and steel products segments were approximately 87% and 78%, respectively, in the first nine months of 2007, compared with 92% and 80%, respectively, in the first nine months of 2006.

The major component of cost of products sold is raw material costs. The average price of raw materials increased approximately 11% from the first nine months of 2006 to the first nine months of 2007, and increased approximately 9% from the third quarter of 2006 to the third quarter of 2007.

In the steel mills segment, the average prices of raw materials used increased approximately 12% from the first nine months of 2006, and increased approximately 10% from the third quarter of 2006. The average scrap and scrap substitute cost per ton used in our steel mills segment was $275 in the first nine months of 2007, an increase of 11% from $247 in the first nine months of 2006, and was $277 in the third quarter of 2007, an increase of 8% from $257in the third quarter of 2006. Nucor incurred a charge to value inventories using the last-in, first-out (LIFO) method of accounting of $102.0 million in the first nine months of 2007, compared with a charge of $45.0 million in the first nine months of 2006. In the third quarter of 2007, the LIFO charge was $11.0 million, compared with a charge of $20.5 million in last year’s third quarter. The LIFO charges (credits) for these interim periods are based on management’s estimates of both inventory prices and quantities at year-end. These estimates will likely differ from actual amounts, and such differences may be significant.

In the steel products segment, the average price of raw materials used increased approximately 6% from the first nine months of 2006 to the first nine months of 2007, and increased approximately 8% from the third quarter of 2006 to the third quarter of 2007.

Total energy costs increased approximately $1 per ton from the first nine months of 2006 to the first nine months of 2007 and increased approximately $1 per ton from the third quarter of 2006 to the third quarter of 2007.

Pre-operating and start-up costs increased to $39.1 million in the first nine months of 2007, compared with $30.0 million in the first nine months of 2006. Pre-operating and start-up costs of new facilities were $14.1 million in the third quarter of 2007, compared with $14.9 million in the third quarter of 2006. In 2007, these costs primarily related to the HIsmelt project in Kwinana, Western Australia, the start-up of the SBQ mill in Memphis, Tennessee, and the building systems facility in Utah. In 2006, these costs primarily related to the HIsmelt project and the refurbishment of our direct reduced iron facility in Trinidad.

Gross margins were approximately 19% for the first nine months and third quarter of 2007, respectively, compared with approximately 24% and 26% for the first nine months and the third quarter of  2006, respectively. In addition to the factors discussed above, gross margins decreased due to a change in product mix.

17

Management’s Discussion and Analysis of Financial Condition and Results of Operations, continued

The major components of marketing, administrative and other expenses are freight and profit sharing costs. Unit freight costs increased approximately 1% from the first nine months of 2006 to the first nine months of 2007 and approximately 4% from the third quarter of 2006 to the third quarter of 2007, primarily due to higher fuel costs. Profit sharing costs, which are based upon and generally fluctuate with pre-tax earnings, decreased approximately 24% in the first nine months of 2007 compared with the first nine months of 2006, and decreased approximately 30% from the third quarter of 2006 to the third quarter of 2007. Profit sharing costs also fluctuate based on Nucor’s achievement of certain financial performance goals, including comparisons of Nucor’s financial performance to peers in the steel industry and to other high performing companies.

Net interest income decreased from $25.8 million in the first nine months of 2006 to $0.6 million in the first nine months of 2007. Average investments decreased 43% primarily due to the cash payment of $1.4 billion for acquisitions and $754.0 million for repurchases of common stock. This decrease was partially offset by an increase in the average interest rate earned on investments. An increase in the average interest rate on debt and the addition of short-term debt assumed with the acquisition of Harris Steel also contributed to the decrease in net interest income.

In the third quarter of 2007, Nucor had net interest expense of $3.6 million compared with net interest income of $10.4 million in the third quarter of the prior year, primarily due to a 71% decrease in average investments.

Minority interests represent the income attributable to the minority owners of Nucor-Yamato Steel Company (“NYS”) and Novosteel S.A., of which Nucor owns 51% and 75%, respectively. Nucor obtained the investment in Novosteel in March 2007 with the acquisition of Harris Steel. Under the NYS limited partnership agreement, the minimum amount of cash to be distributed each year to the partners is the amount needed by each partner to pay applicable U.S. federal and state income taxes.

In the first nine months of 2007 and 2006, the amount of cash distributed to minority interest holders exceeded amounts allocated to minority interests based on mutual agreement of the general partners; however, the cumulative amount of cash distributed to partners was less than the cumulative net earnings of the limited partnership.

Nucor had an effective tax rate of 35.1% in the first nine months of 2007 and in the first nine months of 2006. Nucor had an effective tax rate of 34.8% in the third quarter of 2007, compared with 34.9% in the third quarter of 2006. The Internal Revenue Service is currently examining Nucor’s 2005 federal income tax returns. Management believes that the Company has adequately provided for any adjustments that may arise from this audit.

Net earnings and earnings per share in the first nine months of 2007 decreased 18% and 15%, respectively, to $1.11 billion and $3.68 per diluted share, compared with $1.35 billion and $4.34 per diluted share in the first nine months of 2006. Net earnings and earnings per share in the third quarter of 2007 decreased 27% and 24%, respectively, to $381.2 million and $1.29 per diluted share, compared with $521.6 million and $1.70 per diluted share in the third quarter 2006. The effect of decreased earnings on earnings per share was partially offset by the repurchase of 22.0 million shares of Nucor’s common stock since the second quarter of 2006.

Net earnings as a percentage of net sales were 9% and 12%, respectively, in the first nine months of 2007 and 2006, and were 9% and 13%, respectively, in the third quarter of 2007 and 2006. Return on average stockholders’ equity was approximately 30.5% and 40.3% in the first nine months of 2007 and 2006, respectively.

18

Management’s Discussion and Analysis of Financial Condition and Results of Operations, continued

We expect continued strength in bar, beam, plate and many of our downstream businesses. Market conditions for sheet are slowly improving with more balance between customer inventories and

demand. We are also finally seeing a significant drop in imports, which has helped bring these inventories back into balance. Fourth quarter shipments will be impacted by the usual seasonal and

holiday factors, including scheduled shut-downs at many of our facilities for regular maintenance. The biggest risks to our outlook for the fourth quarter and 2008 remain any further weakening in the economy and any significant reversal of the recent decreases in import levels.

Liquidity and capital resources

The current ratio was 2.3 at the end of the first nine months of 2007 and 3.3 at year-end 2006. The percentage of long-term debt to total capital was 15% at the end of the first nine months of 2007 and at year-end 2006.

Capital expenditures, excluding acquisitions, increased approximately 38% in the first nine months of 2007 compared with the first nine months of 2006. Capital expenditures, excluding acquisitions, are projected to be approximately $600 million for all of 2007.

In September 2007, Nucor’s board of directors declared a supplemental dividend of $0.50 per share in addition to the $0.11 per share base dividend. The total dividend of $0.61 per share is payable on November 9, 2007 to stockholders of record on September 28, 2007.

Nucor repurchased approximately 14.1 million shares of its common stock at a cost of approximately $754.0 million during the first nine months of 2007, and repurchased approximately 11.6 million shares at a cost of about $599.8 million during the third quarter of 2007. Nucor repurchased approximately 10.1 million shares at a cost of about $515.0 million during the first nine months of 2006, and repurchased approximately 6.3 million shares at a cost of about $318.3 million during the third quarter of 2006. In September 2007, the board of directors approved the repurchase of up to an additional 30 million shares of common stock, all of which remain available for repurchase.

In the first quarter of 2007, Nucor sold its interest in Ferro Gusa Carajás S. A. (“FGC”), a pig iron joint

venture in northern Brazil, to its partner, Companhia Vale do Rio Doce (“CVRD”). Nucor has entered into an off-take agreement with CVRD for the production of this facility.

Nucor funded the $1.06 billion cash portion of the purchase price of Harris Steel paid in March 2007 from its cash and cash equivalents and liquidation of short-term investments. Nucor also paid for the acquisition of Magnatrax and other companies during the year with existing funds. Funds provided from operations, existing credit facilities and new borrowings are expected to be adequate to meet future capital expenditure and working capital requirements for existing operations for at least the next 24 months. Nucor believes it has the financial ability to borrow significant additional funds to finance major acquisitions and still maintain its financial strength.

19

Item 3. 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. Nucor also makes use of interest rate swaps to manage net exposure to interest rate changes. Management believes that Nucor’s exposure to interest rate market risk has not significantly changed since December 31, 2006.

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 and natural gas. We attempt to negotiate the best prices for our raw materials and energy requirement and to obtain prices for our steel products that match market price movements in response to supply and demand. Since the first quarter of 2004, Nucor has used a raw material surcharge to pass through the increased cost of scrap steel and other raw materials. Our surcharge mechanism has worked effectively to reduce the normal time lag in passing through higher raw material costs so we can maintain our gross margins.

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 when management believes it is prudent to do so. Gains and losses from the use of these instruments are deferred in accumulated other comprehensive income (loss) on the condensed consolidated balance sheets and recognized into cost of products sold in the same period as the underlying physical transaction. At September 29, 2007, accumulated other comprehensive income (loss) includes $2.7 million in unrealized net-of-tax losses for the fair value of these derivative instruments. A sensitivity analysis of changes in the price of hedged natural gas purchases indicates that declines of 10% and 25% in natural gas prices would reduce the fair value of our natural gas hedge position by $33.0 million and $82.5 million, respectively. Any resulting changes in fair value would be recorded as adjustments to other comprehensive income (loss), net of tax. Because these instruments are structured and used as hedges, these hypothetical losses would be offset by the benefit of lower prices paid for the natural gas used in the normal production cycle.

Foreign Currency Risk – Prior to the acquisition of Harris Steel, Nucor was principally a domestic manufacturer of steel and steel products with customers located primarily in the U.S.  Nucor was exposed to currency fluctuations, however, due to its joint ventures in Brazil and Australia and the direct reduced iron facility in Trinidad.  When the Company entered into the agreement to acquire Harris Steel in January 2007, Nucor became exposed to Canadian currency fluctuations and hedged a portion of the exposure associated with the closing of the transaction in March 2007.  Nucor has not hedged any other foreign currency exposure. The Company continues to be exposed to foreign currency risk through its operations in Canada.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures – As of the end of the period covered by this report, the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures are effective. During the quarter ended March 31, 2007, Nucor acquired Harris Steel. Nucor is in the process of incorporating these operations as part of our internal controls. Nucor has extended its Section 404 compliance program under the Sarbanes-Oxley Act of 2002 and the applicable rules and regulations under such Act to include Harris Steel. Nucor will report on its assessment of its combined operations within the time period provided by the Act and the applicable SEC rules and regulations concerning business combinations.

Changes in Internal Control Over Financial Reporting – There were no changes in our internal control over financial reporting during the quarter ended September 29, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
