Position of strength allows us to capitalize on marketplace opportunities with our flexible growth strategy
– and continue Nucor’s successful tradition as a cyclical growth company.
Nucor’s 4 Pronged Growth Strategy
1) Optimize Existing Operations
2) Pursue Strategic Acquisitions
3) Greenfield Growth – capitalizing on significant cost advantages from new technologies and unique marketplace niches
4) Grow Internationally through joint ventures leveraging new technologies and strategic partnerships

29
•
Develop supplies of high quality scrap substitutes
– control approximately onethird of Nucor’s iron units annual consumption
• Raw materials strategy driven by Nucor’s ongoing expansion of our sheet & SBQ product portfolio into higher quality grades
• At our current consumption rate, will require between
6,000,000 to 7,000,000 tons per year of high quality scrap substitutes
• Major step forward achieved with successful start-up of Nu-Iron direct reduced iron (DRI) plant in Trinidad – with annual capacity of 2 million tons

30
• Sheet Mill Group constructing Nucor’s fourth galvanizing facility
– located at Decatur, Alabama sheet mill. Decatur galvanizing facility will increase Nucor’s total galvanizing capacity by one-third to 2 million tons per year
• Building on successful acquisitions in Decatur of hot rolled sheet mill in 2002 and cold mill in 2004 – Nucor wellpositioned to capitalize on expanding Southeastern
U.S. market for coated sheet steels
• Annual capacity of about 500,000 tons – with ability to galvanize 72-inch wide sheet; cost of project will be approximately $150 million; production start-up in second half of 2008

31
Optimize Existing Operations & Strategic
Acquisition – The
Company
• Agreement signed to purchase The David J. Joseph Co.
for approximately $1.44 billion – closing expected during Q1-2008
• DJJ is one of the leading U.S. scrap companies – processing over 3.5 million tons of ferrous scrap in 2008 utilizing 12 shredders in 35 yards
•
DJJ is more than just a scrap processing company!!!
Other operations include: brokerage services ( ferrous scrap, pig iron, scrap substitutes, ferro-alloys, & non-ferrous materials); mill & industrial services; rail services (owns over 2,000 scrap-related railcars); and, self-service auto parts
• DJJ has been a key partner in Nucor’s growth since 1969.
a member of the Nucor Family, DJJ offers Nucor a
Now, as powerful growth platform in the scrap business while also broadening our raw materials strategy (providing our steelmaking operations a much larger hedge to volatility in scrap markets)

32
• Nucor’s downstream value-added products annual capacity has more than doubled over the past year to 4 million tons.
We have accomplished this with our very successful acquisitions of :
Verco in steel decking ; Harris Steel Group in rebar fabrication , cold finished bars , & metal grating ;
LMP Steel in cold finished bars ;
Magnatrax in metal buildings ; and , Nelson Wire in wire mesh .
• Vertical integration has been a highly successful growth strategy for Nucor for four decades . Nucor’s downstream businesses have consistently generated attractive returns through economic cycles. And, they enhance our steel mills’ performance by providing them a profitable base load of volume .
• Valueadded steel products enhance Nucor’s overall margin and growth opportunities!!!

33
• Bar Mill Group constructing Special Bar Quality (SBQ) products steel mill in Memphis, Tennessee to capitalize on significantly better cost structure compared to key competitors in the SBQ market, both domestic and foreign
• 850,000 tons annual capacity; capital costs reduced dramatically by utilizing the good assets we already have on the ground at
Memphis site
• Expands Nucor’s SBQ product line to rounds & round cornered squares from 2 ¼” to 9” .
Complementing our mills in South Carolina and Nebraska , Memphis SBQ mill will position Nucor to provide the most diverse, highest quality, and lowest cost SBQ product offering in North America
• Production start-up expected in second quarter of 2008

34
• Construction underway at Nucor’s second Castrip® production facility – located at Nucor-Yamato Steel in Blytheville, Arkansas.
Annual capacity of approximately 500,000 tons.
• The time is right for expanding our Castrip ® production capability. Team at Crawfordsville facility building strong momentum in productivity and quality.
Increasing value for
Castrip’s dramatic reduction of energy consumption and environmental impact of steelmaking. Exciting unique product capabilities.
• Production start-up expected in first quarter of 2009 .
• Castrip ® ready to be a significant growth platform for Nucor in the years ahead!!!

35
• Memo of understanding signed in January 2008 with Duferco
Group to establish 50/50 joint venture for the production of beams in Italy and the distribution of beams in Europe & North
Africa.
• Joint venture will encompass Duferco Group’s Duferdofin subsidiary and associated distribution companies . Duferdofin is the leader in beam production in Italy – with output exceeding
900,000 metric tons in 2007 .
With new merchant bar mill under construction , Duferdofin’s total capacity at its 3 Italian plants will exceed 2 million tons . Additional growth projects likely .
• Nucor will contribute its considerable technical and commercial expertise to the joint venture.
Nucor is the largest producer of beams in North America .
• Work underway to establish the joint venture company by mid-2008.

36
• Sheet Mill Group’s growing portfolio of value-added products
(interstitial-free steels, dual-phase steels, complex-phase steels)
• Raw Materials Strategy growing Nucor’s control over supplies of high quality scrap substitutes
• Acquisition of The David J. Joseph Co. as a growth platform in the scrap and raw materials markets
• Expanded capacity in downstream steel products including rebar fabrication, metal buildings, decking, cold finished bars, and wire mesh
• Memphis SBQ mill establishing Nucor with North America’s most diverse, highest quality, & lowest cost SBQ product offering
• Castrip ® technology in sheet steel – Castrip® II facility in Arkansas
• Duferco beam joint venture in Europe

“If, during the bad times, we had failed to look past the shortterm consideration of this quarter’s earnings, would we have gone on to compile such a record of sustained growth and profitability?
I’m certain we would not.”
“ If management had thought of our employees as nothing but “headcount” — a term that seems far more appropriate to cattle than to people would they be as motivated and productive as they are today?
Again, the answer is clearly no.”
