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.

Anglo American advances Teck merger, cuts coal, but De Beers diamond prices slump

Coal asset sale simplifies portfolio ahead of Teck merger Anglo American agreed to sell its Australian steelmaking coal assets for up to $3.88 billion, reducing debt and sharpening focus on copper before merging with Teck. This makes the combined company a top-five copper producer, boosting its appeal to investors betting on electrification and AI power demand.
This is a major strategic move that directly supports the merger and improves Anglo's balance sheet, driving the stock higher.
Teck merger progresses with shareholder election and leadership team Teck mailed merger documents to shareholders, and the two companies named the future Anglo Teck executive team. The merger remains on track to close between September 2026 and March 2027, with projected annual cost savings of about $800 million, reinforcing confidence in the deal's benefits.
These concrete steps show the merger is moving forward, which is central to Anglo's investment case and supports the share price.
De Beers cuts diamond prices sharply as demand weakens Anglo's De Beers unit made some of its deepest ever diamond price cuts, abandoning its long-held strategy of keeping prices above market. Weak Chinese luxury demand and competition from synthetic stones are hurting revenue and margins, weighing on Anglo's earnings and share price.
This is a significant negative development for a key subsidiary, directly impacting Anglo's profitability and investor sentiment.
H1 loss narrows and dividend rises, production outlook maintained Anglo American reported a smaller first-half loss of $858 million, with revenue up 11% and underlying EBITDA up 35%. The interim dividend more than tripled to $0.23 per share, and the company kept its 2026 production guidance, signaling improving financial health and operational stability.
This earnings report shows tangible financial improvement and a commitment to shareholder returns, which supports the stock price.
