He disclosed that negotiations are “at the final stages” with a non-financial services company, and that the talks involve a company planning to set up in the city for the first time.
He said he could not say much more at this time, but added: “It’s at the final stages of negotiation and it will be a big boost for Limerick.”
The news comes in the wake of an announcement by Northern Trust of plans to expand its operation at Plassey National Technology Park with the creation of a further 400 jobs.
Meanwhile Cook Medical, which employs 750 at Plassey, has won approval by the US Food and Drug Administration to sell a stent in the US. The stent has already been given to 15,000 patients in Europe.
Bill Doherty, vice-president of Cook, said the company hopes that FDA approval will help grow job numbers in Limerick.

“There are airline companies, if they thought we were free of Dublin, that would come in and establish flights [at Shannon].”
