$2.6B Senior Notes Offering Proposed
Alcoa announced a proposed $2.6 billion senior notes offering, split between 2034 notes (Alumina Pty Ltd) and 2036 notes (Alcoa Nederland Holding B.V.), to fund the cash portion of the South32 acquisition.
-
Permanent Financing Replaces Bridge Loan
Proceeds plus cash on hand will fund the ~$3.1 billion cash consideration. Alcoa expects to terminate the 364-day bridge term loan facility upon completion of the offering.
-
Pro Forma Debt Rises to $5.42B
Updated pro forma financials show total debt of $5.42 billion after the acquisition and notes issuance, up from $2.225 billion standalone — a significant leverage increase.
-
Assumed Rates of 6.75% and 7.00%
The pro forma assumes $1.3 billion of 2034 notes at 6.75% and $1.3 billion of 2036 notes at 7.00%. A 12.5 bps change in rates would move annual interest expense by ~$3 million.
Analysis · AA · Manufacturing
Alcoa is moving to permanently finance its $4.1 billion South32 acquisition with a $2.6 billion senior notes offering, replacing the bridge loan. The notes carry assumed rates of 6.75% and 7.00%, and the company will use cash on hand to cover the remaining ~$500 million of the $3.1 billion cash consideration. This locks in long-term debt at a time when Alcoa's pro forma total debt would rise to $5.42 billion, roughly 2.4x its LTM pro forma Adjusted EBITDA of $2.2 billion — a meaningful leverage increase that investors need to price in.
