The MMA fighter acquired the Crumlin pub last year, and his Jemi Ventures Ltd recently secured planning permission from Dublin City Council for a large extension.
Accounts filed recently by Jemi Ventures Ltd put a book value of €3.64 million on the pub building and tangible assets at the end of last year, of which €2 million is the value of the buildings.
The pub did not open until July of this year after a seven-figure makeover of the premises. It secured the licence transfer last December.
The company’s cash funds at the end 2020 totalled €665,108. The venture has been financed by a loan of €3.95 million.
The spend forms just part of McGregor’s outlay on property in the Dublin area in recent times. Last month McGregor confirmed plans to build “multiple amenities” on a “mega-site” along Dublin’s Grand canal.
This followed a report that the Crumlin native has paid up to €19 million in nearly completing the assembly of the site on the Davitt Road near the Grand Canal.
Mr McGregor has deep pockets to fund such a venture. Earlier this year McGregor topped the Forbes list of being named the highest paid athlete in the world for 2020/21.
Forbes estimated that in the 12 months to end-May this year McGregor earned $180 million (€153m). The figure includes $158 million from endorsements and the sale of a majority stake in his whiskey brand.
