Terms are now set on a massive $5.5 billion debt raise across five tranches maturing from 2029 to 2056. Coupons range from 4.85% to 6.375%, generating gross proceeds of roughly $5.49 billion. This is the core financing for the $13.5 billion Lhoist North America acquisition, which has already cleared regulatory hurdles.
