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.

CMOC profit surges on higher copper, moly, tungsten prices and gold deal

First-half profit jumps 86% on higher metal prices and volumes CMOC's first-half net profit rose 86.3% to 16.15 billion yuan, with revenue up 42.8%. The gain came from selling more copper and getting higher prices for copper, molybdenum and tungsten, plus adding Brazilian gold mines. Strong earnings and cash flow support the stock price.
This is the core new financial result showing why the company is fundamentally more valuable.
Raises sales caps to CATL, signaling strong battery-metal demand CMOC plans to raise annual sales caps to CATL Group to as much as $5 billion by 2028, and purchase caps from KFM to $14 billion. This points to growing demand for CMOC's copper and cobalt products, which supports future revenue and the stock price.
It shows a concrete new demand signal from a major customer, which affects future earnings.
DRC export ban lifts copper sentiment but has limited real impact The Democratic Republic of Congo banned copper and cobalt concentrate exports, sparking a rally in nonferrous stocks. CMOC says the ban barely affects it because it mostly sells refined copper and cobalt hydroxide, not raw concentrate. Still, the news lifted copper prices, which helps CMOC's revenue.
It explains a new supply-side event that moved the sector and could affect copper prices, a key driver for CMOC.
Halts tailings supply to tungsten joint venture, cutting revenue CMOC stopped supplying tailings to Luoyang Yulu, a joint venture that recovers tungsten. The shutdown cuts a small revenue stream and creates uncertainty, though the financial impact is limited. This is a minor negative for the stock.
It is a new operational setback that could slightly reduce earnings and adds regulatory risk.
