Companies in Ireland with the most long-term debt
Long-term debt is borrowing due more than a year out. A large figure is normal for capital-intensive businesses and says nothing on its own about financial health. Figures are for fiscal year 2025 and are read directly from each company's SEC filings; the source column on every row links to the document.
Aercap Holdings (AER) tops the list with $43.6B in long-term debt for fiscal 2025, ahead of Medtronic ($27.9B) and CRH Public ($16.5B). The top 10 together report $149B in long-term debt; the gap between #1 and #10 is ×10.06. 18 companies in Ireland report long-term debt, 0.8% of the 2263-filer universe. The last place on the list, Amarin, comes in at $49.7M.
