Companies in Luxembourg 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.
Arcelormittal (MT) tops the list with $10.7B in long-term debt for fiscal 2025, ahead of Millicom International Cellular ($6.6B) and SES ($6.5B). The top 10 together report $34.2B in long-term debt; the gap between #1 and #10 is ×56.20. 12 companies in Luxembourg report long-term debt, 0.5% of the 2263-filer universe. The last place on the list, Tenaris, comes in at $368,000.
