Ternium Announces Third Quarter and First Nine Months of 2010 Results

Luxembourg, November 3, 2010 – Ternium S.A. (NYSE: TX) today announced its results for the third quarter and nine-month period ended September 30, 2010.

The financial and operational information contained in this press release is based on Ternium S.A.’s consolidated financial statements prepared in accordance with International Financial Reporting Standards (IFRS) and presented in U.S. dollars and metric tons.

Third Quarter 2010 Highlights

• EBITDA¹ of US$362.3 million in the third quarter 2010, down 20% compared to the second quarter 2010, as a result of higher cost per ton and a slight decrease in shipments and revenue per ton.
• Earnings per American Depositary Share (ADS)² of US$0.76 in the third quarter 2010 compared to US$0.94 in the second quarter 2010.  The third quarter 2010 result includes a US$0.06 after-tax non-cash foreign exchange gain per ADS on Ternium’s Mexican subsidiary’s US dollar denominated net debt, compared to a US$0.10 after-tax non-cash foreign exchange loss per ADS on Ternium’s Mexican subsidiary’s US dollar denominated net debt in the second quarter 2010.
• Collection of US$204.0 million in August 2010 in connection with the transfer of the Sidor shares to Venezuela.  The last payment of US$257.4 million is due during the current month.
• Net cash position of US$0.6 billion at the end of the third quarter 2010.

Ternium’s operating income in the third quarter 2010 was US$267.6 million, a decrease of 26% from US$359.2 million in the second quarter 2010, mainly due to higher cost per ton and slightly lower shipments and revenue per ton.  Cost per ton increased mainly as a result of higher cost for purchased slabs and scrap.  Shipments decreased 21,000 tons in the third quarter 2010 compared to the second quarter 2010, mainly due to a 71,000 ton decrease in shipments in the North America Region, partially offset by increases in the South & Central America and Europe & Other regions.  Revenue per ton decreased US$10 in the third quarter 2010 compared to the second quarter 2010, mainly as a result of lower revenue per ton in the North America Region partially offset by higher revenue per ton in the South & Central America Region.

Operating income in the third quarter 2010 increased US$108.7 million when compared to the third quarter 2009, mainly due to higher shipments and revenue per ton, partially offset by higher cost per ton.  Shipments and revenue per ton in the third quarter 2009 were negatively affected by the global economic downturn that began in the second half of 2008.

Ternium’s net income in the third quarter 2010 was US$200.8 million, a decrease of US$29.8 million compared to the second quarter 2010 mainly due to a US$91.6 million decrease in operating income partially offset by a US$64.9 million increase in non-cash net foreign exchange results mainly related to Ternium’s Mexican subsidiary’s US dollar denominated net debt (which was offset by changes in Ternium’s net equity position).

Net income in the third quarter 2010 increased US$96.2 million when compared to the third quarter 2009.  The year-over-year change in net income was mainly driven by the above mentioned US$108.7 million increase in operating income and a US$79.7 million increase in non-cash foreign exchange results mainly related to Ternium’s Mexican subsidiary’s US dollar denominated net debt (which was offset by changes in Ternium’s net equity position), partially offset by a US$72.3 million increase in income tax expense.

First Nine Months of 2010 Highlights

• EBITDA³ of US$1.2 billion in the first nine months of 2010, an increase of US$807.7 million compared to the first nine months of 2009, mainly due to higher shipments and revenue per ton, partially offset by a higher cost per ton.
• Earnings per ADS of US$2.72 in the first nine months of 2010, compared to US$2.78 in the first nine months of 2009.  The first nine months of 2009 included a US$2.05 after-tax discontinued operations gain as a result of the transfer of the Sidor shares to Venezuela.  The first nine months of 2010 result includes a US$0.28 after-tax non-cash foreign exchange gain per ADS on Ternium’s Mexican subsidiary’s US dollar denominated net debt, compared to a US$0.02 after-tax non-cash foreign exchange gain per ADS on Ternium’s Mexican subsidiary’s US dollar denominated net debt in first nine months of 2009.
• Collection of US$767.4 million during the first nine months of 2010 in connection with the transfer of the Sidor shares to Venezuela.

Ternium’s operating income in the first nine months of 2010 was US$920.3 million, compared to  US$80.3 million in the first nine months of 2009.  The increase was mainly due to an additional 1.2 million tons in shipments and US$148 in revenue per ton, partially offset by a slightly higher operating cost per ton.  Shipments and revenue per ton in the first nine months of 2009 were significantly impacted by the global economic downturn during the period.

Net income was US$676.6 million in the first nine months of 2010, US$104.3 million higher  than net income in the first nine months of 2009.  There were no discontinued operations results in the first nine months of 2010, whereas there was a US$428.0 million discontinued operations gain in the first nine months of 2009 related to the transfer of the Sidor shares to Venezuela.  The year-over-year change in net income was also driven by the above mentioned US$839.9 million increase in operating income and a US$89.3 million increase in non-cash net foreign exchange results mainly related to Ternium’s Mexican subsidiary’s US dollar denominated net debt (which was offset by changes in Ternium’s net equity position) partially offset by a US$377.2 million change in income tax results.

Outlook

Ternium anticipates that steel demand in Latin America, driven by solid economic growth, will continue to recover.  However, as a result of normal seasonal patterns, the company’s shipments in the coming quarters are expected to remain relatively stable compared to shipment levels in the third quarter 2010.

The company anticipates a decrease in operating margin in the fourth quarter 2010 compared to the third quarter 2010 as a result of lower prices and higher cost per ton.  The increased raw material and purchased slabs prices during the second and third quarter 2010 are expected to continue being gradually reflected in Ternium’s cost of sales during the fourth quarter 2010.

Net income attributable to Ternium’s equity holders in the third quarter 2010 was US$151.7 million, compared to US$88.5 million in the third quarter 2009.  Including minority interest, net income for the third quarter 2010 was US$200.8 million, compared to US$104.7 million in the third quarter 2009.  Earnings per ADS in the third quarter 2010 were US$0.76, compared to US$0.44 in the third quarter 2009.

Sales of long products were US$217.0 million in the third quarter 2010, an increase of 48% compared to the same period in 2009 mainly due to higher shipments and revenue per ton.  Shipments of long products totaled 347,000 tons in the third quarter 2010, a 28% increase versus the same quarter in 2009 mainly due to higher billets shipments in the South & Central America Region.  Revenue per ton shipped was US$625 in the third quarter 2010, an increase of 16% compared to the second quarter 2009, mainly due to higher prices in Ternium’s main steel markets.

Sales of other products totaled US$40.7 million during the third quarter 2010, compared to US$21.2 million during the third quarter 2009.  The increase was mainly driven by higher iron ore shipments and prices.

Sales of flat and long products in the North America Region were US$994.5 million in the third quarter 2010, an increase of 27% versus the same period in 2009, mainly due to higher revenue per ton.  Shipments in the region totaled 1.2 million tons during the third quarter 2010, or 4% higher than in the same period in 2009 as a result of higher shipments in Mexico, offset by lower shipments in the U.S.  Revenue per ton shipped in the region increased 22% to US$860 in the third quarter 2010 over the same quarter in 2009, mainly due to higher prices.

Flat and long product sales in the South & Central America Region were US$822.4 million during the third quarter 2010, an increase of 80% versus the same period in 2009.  This increase was due to higher shipments and revenue per ton.  Shipments in the region totaled 821,000 tons during the third quarter 2010, or 52% higher than in the third quarter 2009, mainly due to a recovery from the 2009 global economic downturn.  Revenue per ton shipped was US$1,002 in the third quarter 2010, an increase of 19% compared to the same quarter in 2009, mainly due to higher prices.

Cost of sales totaled US$1.4 billion in the third quarter 2010 compared to US$1.0 billion in the third quarter 2009.  Cost of sales increased mainly due to higher shipments and higher cost per ton.  Cost per ton increased as a result of higher raw material costs and higher maintenance and labor costs.

Selling, General & Administrative (SG&A) expenses in the third quarter 2010 were US$170.1 million, or 9% of net sales, compared with US$114.6 million, or 9% of net sales, in the third quarter 2009.  The US$55.5 million year-over-year increase was mainly due to higher freight expenses and taxes related to higher shipment levels and higher labor cost.

Operating income in the third quarter 2010 was US$267.6 million, or 14% of net sales, compared with an operating income of US$158.9 million, or 12% of net sales, in the third quarter 2009.

Net foreign exchange result was a gain of US$32.0 million in the third quarter 2010 compared to a loss of US$47.6 million in the same period in 2009.  The third quarter 2010 gain was primarily due to the impact of the Mexican Peso’s 1.23% revaluation on Ternium’s Mexican subsidiary’s US dollar denominated debt.  This result is non-cash when measured in US dollars and is offset by changes in Ternium’s net equity position in the currency translation adjustments line, as the value of Ternium Mexico’s US dollar denominated debt is not altered by the Mexican Peso’s fluctuation when stated in US dollars in Ternium’s consolidated financial statements.  In accordance with IFRS, Ternium Mexico prepares its financial statements in Mexican Pesos and registers foreign exchange results on its net non-Mexican Peso positions when the Mexican Peso revaluates or devaluates relative to other currencies.

Interest income on the Sidor financial asset was US$11.6 million in the third quarter 2010 compared to US$38.3 million in the third quarter 2009.  These results are attributable to the Sidor financial asset in connection with the transfer of Sidor shares on May 7, 2009.

Cash Flow and Liquidity

Net cash provided by operating activities in the first nine months of 2010 was US$581.4 million, compared to US$1.1 billion in the first nine months of 2009.  While operating results were US$840.0 million higher in the first nine months of 2010 compared to the first nine months of 2009, there was a US$485.0 million increase in working capital in the first nine months of 2010 compared with a US$847.4 million decrease in working capital during the first nine months of 2009.  The increase in working capital in the first nine months of 2010 included an increase of US$576.7 million in inventory, reflecting higher inventory volume as a result of higher operating rates, and higher costs of finished goods, goods in process and raw materials.  The decrease in working capital in the first nine months of 2009 included a US$660.5 million inventory reduction, reflecting a decrease in inventory volume as Ternium implemented a de-stocking process in response to lower demand for steel products, and lower costs of finished goods, goods in process and raw materials.

Capital expenditures in the first nine months of 2010 were US$220.0 million, compared to US$145.8 million in the first nine months of 2009.  During the first nine months of 2010 Ternium carried out, among other projects, the relining of a blast furnace, the expansion of the hot strip mill and enhancements in the coking facilities in Argentina, and the upgrading of a cold strip mill and the development of Ternium’s mining activities in Mexico.

In the first nine months of 2010, Ternium generated free cash flow⁴ of US$361.4 million, compared to free cash flow of US$943.4 million in the first nine months of 2009.  In addition, proceeds from the transfer of shares of Sidor to Venezuela totaled US$767.4 million in the 2010 period.  Ternium acquired Ferrasa on August 25, 2010 through a capital contribution in the amount of US$75 million.  Ternium’s net repayment of borrowings in the first nine months of 2010 was US$537.0 million, mostly related to

the scheduled repayments of Ternium Mexico’s outstanding debt, while dividends paid in cash to shareholders and minority shareholders totaled US$138.5 million in the same period.  As of September 30, 2010, Ternium’s net cash position was US$0.6⁵ billion, including Ferrasa’s net debt of US$128.6 million.
