Hyundai Heavy Industries Holdings Co. (HHIH) and ready-mixed concrete maker Eugene Group on Tuesday submitted their final bids for a 36 percent stake in Doosan Infracore Co., the largest local construction equipment maker here.

In a regulatory filing, the shipbuilder said that it has joined the final bid, with Eugene Group reportedly joining the final bid.

But GS Engineering & Construction Corp. and three local private equity funds -- Glenwood PE, MBK Partners and Eastbridge Partners dropped its main bid for the stake.

In September, HHIH formed a consortium with Korea Development Bank Investment (KDBI), a unit of the state-run Korea Development Bank (KDB), to join preliminary bidding for the stake up for sale.

GS Engineering & Construction participated in the preliminary deal by forming a consortium with private equity fund Dominus Investment.

Three local private equity funds joined in the preliminary deal.

Doosan Infracore invited final bidders on the day, a development that would help stave off a liquidity crisis at its parent Doosan Group.

Doosan Infracore has been up for sale as part of its cash-strapped parent Doosan Heavy Industries & Construction Co.'s self-rescue plan.

The deal may fetch up to 1 trillion won ($900 million), according to the companies.

Last March, Doosan Heavy obtained a cash injection of 3 trillion won from its creditors, including the KDB, to prepare itself for its short-term debts worth 4.2 trillion won, which should be paid within this year. (Yonhap)
