Animal health and nutrition company Alltech is to create 100 new jobs in Dunboyne, Co Meath.
The move will double Alltech's workforce in Dunboyne to more than 200 at the firm's European headquarters.
And the new jobs will be mainly in the research and science areas.
As a result of the expansion researchers, who specialise in cellular biotechnology, are expected to double from 30 to 60, through a €10m investment.
Already, its newly expanded bioscience centre has trebled the capacity of the facility.
"This facility is Dunboyne has gone from strength to strength since it first opened," said Fine Gael Meath East TD Regina Doherty, who welcomed the move.
In the meantime, Alltech brings its Global 500 networking opportunity to Europe for the first time.
It will take place between October 1 and 3 in the RDS, Dublin.
