DUBAI, Jan 3 (Reuters) - International Holding Company (IHC), an Abu Dhabi conglomerate led by a key member of the United Arab Emirates' ruling family, has formed a new holding company that will hold a $27 billion portfolio across industries from asset management to mining.

The portfolio will be transferred into the new entity 2PointZero from Royal Group, after obtaining regulatory approvals, IHC told Reuters in a statement on Wednesday. Royal Group is IHC's biggest shareholder owning a 61% stake in the company and part of Sheikh Tahnoon bin Zayed al-Nahyan's business empire.

2PointZero's portfolio will include alternative asset manager Lunate, which last month launched a $30 billion climate fund dubbed ALTÉRRA at COP28, in collaboration with global asset managers BlackRock, Brookfield and TPG.

International Resources Holding, which invested $1.1 billion in Zambia's Mopani Copper Mines in December and focuses on energy transition minerals, will also be transferred to the portfolio.

Formerly known as International Fish Farming Holding, IHC went from an obscure seafood producer and distributor and real estate investor and developer to a major conglomerate with a market capitalisation that has ballooned since 2020 to $240 billion, double the size of global alternative asset manager BlackRock.

Egyptian financial services firm Beltone Holding , which is 56% owned by Royal Group, is also earmarked for 2PointZero, pending regulatory approval.

Shares of Cairo-listed Beltone Holding jumped by more than 10% in early trade before they were suspended from trading on the Egyptian exchange.

IHC is part of a business empire overseen by its chair, Sheikh Tahnoon bin Zayed al-Nahyan, who is also the UAE's national security adviser and a foreign policy troubleshooter for his brother, President Sheikh Mohammed bin Zayed al-Nahyan.

Sheik Tahnoon is at the helm of two of Abu Dhabi's biggest wealth funds, Abu Dhabi Investment Authority and ADQ, and also chairs First Abu Dhabi Bank, the UAE's biggest lender by assets.

Shares of IHC jumped as much as 3.2% in early morning trade on Wednesday.

Private investment firm Chimera Investments, special purpose vehicle Sagasse Investments and Citadel Technologies, which operates a crypto mining plant in Abu Dhabi and specializes in Bitcoin extraction, are also earmarked for 2PointZero.
