California Steel Industries Reports Fourth Quarter and Full Year 2010 Results

Fontana, CA.— California Steel Industries, Inc. (“CSI”) today reported profitable results for the year ending December 31, 2010, with net sales of $1.08 billion and net income of $25.4 million.

These results compare with net sales of $551.8 million and a net loss of $13.1 million for the year ending December 31, 2009.

The net loss for fourth quarter 2010 is $5.5 million, compared with a net loss of $2.3 million in fourth quarter 2009 and net income in third quarter 2010 of $2.0 million. Net sales for the quarter are $227.9 million, or 48 percent higher than fourth quarter 2009’s net sales of $153.6 million, but 27 percent less than third quarter 2010’s net sales of $313.9 million.

Shipments in fourth quarter 2010 are 279,641 net tons, 26 percent higher than fourth quarter 2009’s shipments of 222,242 net tons and 24 percent lower than third quarter 2010 shipments of 365,608 net tons.

For the year, CSI shipped 1,335,256 net tons, 67 percent higher than 2009’s shipments of 800,375 net tons.

The Company recorded $4.6 million in fourth quarter 2010 and $12.9 million in fiscal 2010 for writing down inventory to market value as CSI’s inventory values are carried at the lower of cost or market (LCM).

“Fourth quarter 2010 results are normally impacted by the lower shipment levels we experience during this period each year,” said Vicente Wright, President & Chief Executive Officer.

“But rather than focus on a quarter whose results are cyclical and thus typically diminished from the rest of the year, I look at the total results for fiscal 2010, and recognize the tremendous survival measures taken by our team and the resulting turnaround from 2009,” he continued.

“The results for 2010 not only indicate an improvement to business conditions in the US, but also can be directly attributed to our Company’s efforts to position itself to meet future changing conditions,” Mr. Wright concluded.

EBITDA (as adjusted) for the quarter is $4.0 million, lower than fourth quarter 2009’s adjusted EBITDA of $9.1 million, and also lower than third quarter 2010’s adjusted EBITDA of $21.3 million.

For the year, EBITDA (as adjusted) is $88.2 million, 52 percent higher than 2009’s adjusted EBITDA of $58.2 million.

The balance under the Company’s Revolving Credit Agreement was zero as of December 31, 2010, with availability of $110 million. The Company has a cash balance as of December 31, 2010 of $27.7 million.
