Thor Equities LLC is among New York's biggest landlords. It has offered more than US$2.1 billion in cash to acquire Empire State Building. This was stated by the real estate firm's broker on Thursday.

The Empire State Building was set to become the centerpiece of a publicly traded real estate investment trust. The interest of pursuing an acquisition deal from Thor Equities marked a third offer for the building.

The offer was confirmed by Thor Equities but did not admit on the price of the deal. A representative from Malkin Holdings LLC could not immediately confirm the offer and refused to give any further statements. Malkin Holdings LLC is the overseer of the Empire State.

The offer from Thor Equities was all in cash according to its Broker Jason Meister of Avison Young.

Earlier this week, Malkin Holdings wrote a letter to its investors. The letter stated its review of two unsolicited offers priced at US$2.1 billion and the other at US$2 billion. This was disclosed through a filing with the US Securities and Exchange Commission.
