Insulation and building materials manufacturer Kingspan has raised €750m in its first public bond offering.
The bond has a fixed coupon of 3.5% a year on a seven-year term.
Kingspan said that demand for the bond was "significantly oversubscribed" with the initial order book attracting bids of more than €3.5 billion.
Geoff Doherty, Kingspan's group CFO, said this marked another capital market milestone for the Co Cavan-based company.
"In making our debut into public debt markets we have opened a highly liquid capital pool on attractive terms to fund the next wave of our global growth. We are firmly committed to our strong investment grade rating," he added.
Kingspan is rated as a strong investment grade credit, BBB stable, by both S&P and Fitch credit rating agencies.
