Commenting, Lakshmi N. Mittal, Chairman and CEO, Mittal Steel Company, said:
“2004 was an excellent year for Mittal Steel. We experienced a strong demand for our products across all markets, combined with higher selling prices and a substantial rise in our total shipments due to the completion of a number of key strategic acquisitions. This resulted in record results for the company. Our focus has always been to be a low-cost producer and this is reflected in our operating margin of 27.7%.
Mittal Steel has now built positions of strength across our key three operating regions: Americas, Europe and the Rest of the World. Looking forward, we are anticipating stable demand during 2005. Global supply and demand remains fairly balanced and Mittal Steel is well positioned to take advantage of the current market dynamics.”
