South32 sells its aluminium arm to Alcoa, and copper supply tightens

Alcoa buys South32's aluminium assets for up to $5.6B South32 agreed to sell its bauxite, alumina and aluminium businesses to Alcoa for about $4.1B upfront — $3.1B cash plus Alcoa shares — and up to $750M more if prices stay high. Cash and a simpler, smaller company support the shares.
The asset sale is the single biggest force on S32.LSE this period, reshaping the company and bringing in cash.
Alcoa locks in funding, moving the sale closer to done Alcoa raised $2.6B of debt and closed its financing package to pay the cash part of the deal. That makes completion more likely, though it still needs shareholder and regulatory approvals — so the cash is not certain yet.
Financing progress is new and directly affects whether South32 actually receives the deal proceeds.
Copper prices rise on tight supply Copper futures rose as inventories fell and Chilean output disappointed — including South32's own weather-hit mine. Higher copper prices help South32's remaining copper business, though the mine miss shows it is not getting full benefit from those prices.
Copper is a core South32 commodity, so tighter supply and higher prices lift its earnings outlook.
Alcoa's strong quarter supports the deal, but aluminium demand is the risk Alcoa posted record revenue and profit, helped by higher aluminium prices, which supports the value of the contingent payment South32 may receive. But the deal leaves South32 smaller and more exposed to copper and other metals, and the contingent payout depends on prices staying high.
It is the real counterweight: the sale is positive, but it shrinks South32 and ties extra value to future aluminium prices.
