Esmark and NLMK-Duferco Joint Venture to Make Joint Bid to Acquire Winner Steel.

CHICAGO -- Esmark Incorporated, along with a joint venture partnership including Russia's Novolipetsk Steel (NLMK) and Switzerland-based Duferco Group, today announced that Esmark and Duferco U.S. Investment Corporation have formed a consortium to purchase the assets of Winner Steel, based in Sharon, Pennsylvania. Terms of the proposed acquisition bid were not disclosed.

Duferco U.S. Investment Corporation is a wholly-owned subsidiary of Steel Invest & Finance S.A. (Luxembourg), a 50/50 joint venture between Duferco Group and Novolipetsk Steel.

The consortium has entered into a letter of intent with Winner Steel to purchase Winner's galvanized steel production facilities, which is subject to negotiation and execution of a definitive asset purchase agreement and other conditions.

In commenting on the consortium's bid to acquire Winner Steel, James P. Bouchard, Chairman and CEO of Esmark, noted that Esmark's strong relationship with Duferco and its long-term slab arrangement in the event of its proposed merger with Wheeling-Pittsburgh Steel Corporation (NASDAQ:WPSC) would further strengthen Esmark's footprint in the Midwest steel corridor.

"Esmark continues to add strategic assets to expand its product capabilities to better serve our loyal customer base. The addition of Winner Steel's galvanized steel production assets, combined with Duferco's neighboring Farrell facility, will allow Esmark to bolster its converter operations, service center network and pre-painted division and provide customers with a value-added, just-in-time solution," said Bouchard. "The combination of our international partners' resources and expertise and Esmark's low-cost service center model will help us expand on our growth strategy in the U.S. marketplace."

Winner Steel is one of the largest independent galvanized steel producers in the United States. Its operations are located on a single site in Pennsylvania and include three galvanizing lines with combined annual capacity of around 1.2 million tons and 2006 production of approximately 800,000 million tons.

The main applications of the galvanized steel produced by the company are in the construction, appliances and automotive industries. Winner Steel is located close to Farrell facility, which is already part of the NLMK-Duferco joint venture, and is one of the primary suppliers of cold-rolled steel to Winner Steel and the galvanizing segment of the industry.

Alexey Lapshin, NLMK President and the Board Member of Steel Invest and Finance S.A., said:

"We welcome this development in the business of our joint venture with Duferco Group. It will provide for an increase in value-added products and further expansion into the large North American market. We are delighted to have Esmark, one of the most dynamic companies in the U.S. steel industry, as our partner in this project."

Benedict Sciortino, Director of Duferco Group and a Board Member of Steel Invest and Finance S.A., said:

"Being located just next to our Farrell facility in Sharon, Winner Steel is a logical component of our North American growth strategy. The acquisition is likely to create substantial synergies by ensuring a stable supply of cold-rolled material to Winner Steel and by increasing the downstream exposure of the NLMK-Duferco joint venture. We are delighted to work together with Esmark on this transaction and are hopeful that it will lead to successful joint projects in the future."

The Winner Steel transaction, which is subject to the negotiation and execution of a definitive agreement and regulatory approvals, is expected to be completed in the second quarter of 2007.
