CRU North American Steel Price Index CRU North America Steel Price Index NCI The CRU North American Steel Price Index has been published by the CRU since 1994. It’s based on a survey of industry participants and is commonly used in the settlement of physical and financial contracts within the steel industry. The prices surveyed are purchases for forward delivery, according to lead time, which will vary by approximately one to two months. To better align with NCI’s fiscal year, the values shown are from October of each year. (1994 Index = 100)

Losses are not allocated to participating securities because they are not contractually obligated to fund or otherwise share in those losses. (2) Example B assumes that stock options are dilutive after having applied the treasury stock method. (3) If using the “if converted” method resulted in lower diluted earnings per share than the two class method, the lower amount would generally be reported. However, given the Company’s capital structure, this is not likely to occur.

Convertible Preferred Stock Key Terms Regarding Dividend Payments Dividends may be paid in cash (8% annual rate) or in-kind (12% annual rate) at the Company’s option:• Dividend payment dates: March 15^th, June 15^th, September 15^thand December 15^th.• Credit facility restrictions:• Both our ABL Facility and Term Loan Credit Facility restrict our ability to pay cash dividends until the first quarter of fiscal 2011.• Thereafter, cash dividend payments are generally limited to 50% of the consolidated net income accumulated subsequent to August 2, 2009, subject to specified adjustments, less the sum of all previous distributions.• Dividend Elimination or “knock-out”:• The dividend rate becomes 0% permanently, if at any time after April 2012 the trading price of our common stock exceeds $12.75 (adjusted for stock splits, etc.) for 20 consecutive trading days. However, in the event of a default, as defined, certain penalty dividends may be required. Summary of Preferred and Common Stock Outstanding at Aug. 1, 2010: Number of Shares of Common Stock, if converted (millions) Series B Convertible Preferred Stock 43.0 Common Stock 18.3 Unvested Restricted Common Stock 1.3 Total Outstanding Shares, if converted 62.6 The liquidation preference of the Series B Convertible Preferred Stock, including accrued unpaid dividends, was $274.3 million

Simplified Beneficial Conversion Feature (BCF) Charge Illustration for Paid In-Kind Dividends The following table illustrates a few selected dates out of a full quarter’s calculation of the BCF charge on our Paid In-Kind Dividends: (Dollars and shares in thousands, except per share information) Shares of Daily Conversion Closing BCF Amount Common Total BCF Charge Dividend Price Per Stock Per Converted Stock, if (Assuming stock price Accrual (1) Share (2) Price Common Share Converted of $8 to $15) (3) Day 1 $86.2 $6.374 $10.00 $3.626 13.5 $49.1 Day 2 86.2 6.374 5.00 — 13.5 -Day 3 86.2 6.374 12.00 5.626 13.5 76.1 ...

The daily dividend amount is accrued at an annual rate of 12% but if it is later paid in cash instead of in-kind, the excess 4% dividend and the related beneficial conversion feature charge would be eliminated in the period in which it is paid. The Company has the option to pay the dividends in cash at 8% or in-kind at 12%, subject to restrictions in the credit facilities for our term loan and ABL revolver. Further, if at any time after April 2012, our stock trades above $12.75 for 20 consecutive trading days, the underlying basic preferred stock dividends are permanently eliminated thereafter. (2) The conversion price of $6.374 reflects the adjustment for the one-for-five reverse stock split that occurred in March 2010. (3) The amount of the beneficial conversion feature charged in any quarter will be the sum of the daily BCF amounts calculated as illustrated above and will depend on the daily closing price of our stock in relation to the $6.374 conversion price. The charge is limited or “capped” at the underlying dividend amount. As an example, based on a daily stock price ranging between $8 and $15, the estimated quarterly charge would be $2 million to $7.9 million. _ 51
