AGY Holding Corp. Announces 2010 Third Quarter Consolidated Results

and Earnings Conference Call

AIKEN, SOUTH CAROLINA—(November 12, 2010)—AGY Holding Corp. (“AGY” or the “Company”) reports its 2010 third quarter results highlights.

Summary Financial Performance

($ in millions)

See Appendix D where EBITDA and Adjusted EBITDA are defined and reconciled from net income (loss) determined under GAAP.

Net sales in the third quarter of 2010 were $45.6 million, which consists of $38.9 million of revenue reported by AGY US and $6.7 million of sales reported by AGY Asia (after accounting for the elimination of $1 million of intercompany sales).

AGY US—Revenues in the third quarter of 2010 increased by $3.4 million, or 9.5%, compared to the third quarter of 2009, due to higher sales volumes and a favorable sales mix, partially offset by competitive pricing pressures. Market demand has been stable in most markets that AGY US served during the third quarter of 2010, with some softening related to seasonal influences compared to the second quarter 2010. Aerospace sales increased by $0.8 million, or 11.5%, for the third quarter of 2010 compared to the third quarter of 2009 and returned to 2008 average demand levels, reflecting primarily increases in both aircraft retrofit and new build activity. The industrial and construction market revenues increased approximately $3.7 million and $0.4 million, respectively. The electronics market revenues were $1.0 million below the third quarter of 2009 and the second quarter of 2010 level reflecting some traditional seasonal softening in Asian market demand. We also experienced some capacity-constrained sales for some of our high-end electronics glassfibers as we rationalized our North American manufacturing footprint. Defense revenue decreased $0.5 million in the third quarter of 2010, compared to the same period of 2009, mainly as the result of price erosion while volumes were essentially flat.

AGY Asia—This business segment reported in the third quarter of 2010 its highest sales since the June 2009 acquisition of AGY Asia of $7.7 million, which represents a 24% improvement compared to the third quarter of 2009 due to increased demand in the Asian electronic market, increased export sales to Europe and favorable pricing.

The Company reported a loss from operations for the third quarter of 2010 of $0.9 million, compared to loss from operations of $6.3 million reported in the third quarter of 2009. Improved sales, plus improved manufacturing efficiencies and cost reductions, are the main drivers of these operating performance gains for AGY US and AGY Asia. The operating results of these business segments improved by $4.1 million and $1.3 million, respectively. These improvements were partially offset during the third quarter of 2010 by incremental restructuring and accelerated depreciation charges of $2.3 million (or a total of $6.1 million year-to-date) associated with AGY North American footprint optimization, which we believe will, over the long-term, improve our profitability and our overhead cost structure. In addition AGY US profitability benefited during the third quarter 2010 from improved operating leverage of overhead costs at increased production capacity level compared to the same period in 2009.

AGY reported consolidated net losses attributable to the Company of $6.7 million and $7.5 million for the third quarters of 2010 and 2009, respectively. The increase in operating profitability during the third quarter of 2010 compared to the same period of 2009 was partly offset by a $4.0 million tax benefit reduction due primarily to establishment of valuation allowance during the third quarter of 2010 for domestic deferred tax assets based on the projection that the amount of tax benefits from net operating losses for the full 2010 calendar year will be limited by the amount of available deferred tax liabilities.

Adjusted EBITDA, a measure of operating performance used by management of AGY, was $5.6 million during the third quarter of 2010, compared to Adjusted EBITDA loss of $2.1 million for the comparable period of 2009. Improved operating results in the third quarter of 2010 compared to the same period in 2009 resulted from increased market demand and sales margin, as well as improved manufacturing efficiencies and cost reduction initiatives in our AGY US and AGY Asia business segments. AGY US contributed $4.1 million of Adjusted EBITDA during the third quarter of 2010, or a $6.8 million improvement over the third quarter of 2009. AGY Asia positively impacted the Company’s results with a $1.5 million Adjusted EBITDA for the third quarter of 2010, an increase of $0.9 million from third quarter 2009. For the first nine months of 2010 Adjusted EBITDA attributable to AGY Holding Corp. was $19.4 million, compared to the $0.2 million reported for the comparable period of 2009.

The Company’s consolidated cash balance as of September 30, 2010 was $5.2 million. Total debt, net of cash as of September 30, 2010, was $227.1 million, a year-to-date decrease of $2.0 million, of which $2.9 million was attributable to AGY Asia to support primarily the upgrade in manufacturing technology necessary for future growth of AGY Asia’s operations.

“We are pleased with our results for the third quarter. While we experienced some moderation of our sales growth this quarter principally for our AGY US business segment, which is due in part to traditional seasonal effects, we were able to sustain prior quarter’s EBITDA margin of 12% with a lower revenue base”, commented Doug Mattscheck, President and Chief Executive Officer. “We have now completed the major milestones of our North American footprint optimization and the investment in restarting capacity to meet the demands of our customer base; we started to experience improved manufacturing efficiencies in the later part of this quarter, which should drive increased operating profits along with our new improved cost structure. Finally, our continued strict working capital management and improved operating results reflected in an increased and positive cash generation for both our AGY US and AGY Asia business unit in the third quarter.’’

Reconciliation of Net Income to EBITDA and Adjusted EBITDA

(Dollars in thousands, unless otherwise noted)

The Company’s management uses EBITDA and Adjusted EBITDA, which are non-GAAP financial measures, to measure operating performance. The most directly comparable financial measure determined under GAAP is net income (loss), the calculation of which for the three months ended September 30, 2010 and 2009 is set forth on Appendix B.

EBITDA and Adjusted EBITDA (which are defined below) are reconciled from net loss determined under GAAP as follows (dollars in thousands):

EBITDA is defined as earnings before interest, taxes, depreciation and amortization. EBITDA is a non-GAAP financial measure used by management to measure operating performance. EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income as a measure of operating performance or to cash flows from operating activities as a measure of liquidity. Additionally, EBITDA is not intended to be a measure of free cash flow available for management’s discretionary use, as it does not consider certain cash requirements such as interest payments, tax payments and debt service requirements. Management believes EBITDA is helpful in highlighting trends because EBITDA excludes the result of decisions that are outside the control of operating management and can differ significantly from company to company depending on long-term strategic decisions regarding capital structure, the tax jurisdictions in which companies operate and capital investments. In addition, management believes EBITDA provides more comparability between AGY’s historical results and results that reflect purchase accounting and changes in AGY’s capital structure. Management compensates for the limitations of using non-GAAP financial measures by using them to supplement GAAP results to provide a more complete understanding of the factors and trends affecting the business than GAAP results alone. Because not all companies use identical calculations, these presentations of EBITDA (as well as Adjusted EBITDA) may not be comparable to other similarly titled measures of other companies.

Adjusted EBITDA is a non-GAAP financial measure which is defined as EBITDA further adjusted as permitted and calculated in the manner that consolidated cash flow is calculated under the indenture governing the Company’s senior secured notes, relative to certain provisions, including but not limited to, restricted payments and incurrence of additional indebtedness.
