London, Jan 17, 2026, 07:53 GMT — The market is now closed.
- Glencore slipped 2.5% on Friday, erasing some of its recent gains.
- UK takeover rules impose a Feb. 5 deadline for any Rio Tinto bid, leaving the stock in focus through next week.
- Investors eye takeover-code disclosures, weigh China approval risks, and await Glencore’s production update due in late January.
Glencore (GLEN.L) shares closed Friday 2.53% lower at 478.6 pence. Investors remain cautious heading into the weekend, weighing the likelihood of a deal with Rio Tinto. 1
The UK Takeover Panel’s disclosure table names Rio Tinto as the offeror for Glencore, setting a Rule 2.6 deadline at 5 p.m. London time on Feb. 5. This “put up or shut up” deadline requires the bidder to make a firm offer or withdraw. 2
The timetable is crucial—it makes Glencore a stock that reacts sharply to headlines. Any fresh filing, whisper, or regulatory signal can jolt its shares, particularly since the market is closed on weekends and trading volumes are thin between sessions.
Glencore fell on Friday after closing Thursday at 491.0 pence. The stock bounced between 475.75 pence and 488.45 pence during the day, with roughly 61.9 million shares traded, per published data. 3
In Australia, a number of long-term investors remain cautious about the timing. Mark Freeman, managing director of Australian Foundation Investment Company, noted that Rio Tinto faces “a lot of questions” about how a merger would generate value, adding: “There are a lot of scars.” 4
Regulation remains a major hurdle. Analysts and legal experts told Reuters that a Rio Tinto-Glencore merger could trigger asset sales to appease China, the biggest buyer of key mined commodities. Copper and iron ore will likely be under close scrutiny. Glyn Lawcock, an analyst at Barrenjoey in Sydney, said: “China will see this as an opportunity to squeeze out assets.” Mark Kelly, CEO of advisory firm MKI Global Partners, added the deal would be “long” and “complicated” from a regulatory standpoint. 5
The takeover is triggering mandatory disclosures. BlackRock submitted a Form 8.3 — the UK Takeover Code requirement for investors holding 1% or more — revealing it owned 7.13% of Glencore’s ordinary shares as of Jan. 15, plus some smaller derivative stakes. 6
European mining stocks dropped on Friday, hurt by easing geopolitical tensions that undercut safe-haven metals prices and dragged the sector lower. The broader market offered no relief heading into the close. 7
Glencore has outlined its key upcoming dates. The miner will release its 2025 full-year production report on Jan. 29, followed by full-year earnings on Feb. 18. A webcast is set for 8:30 a.m. UK time that day. 8
The downside is straightforward. If the bid process hits a snag or regulators force divestments that undermine the deal’s rationale, the stock could plummet fast — and miners can lose favor just as quickly when commodity prices drop.
As London trading kicks off Monday, investors will be on the lookout for more takeover-code filings and any fresh comments from the companies involved. They’ll also be digging for signs of how China might react to the deal. Key dates ahead include Glencore’s production report on Jan. 29 and the takeover deadline set for Feb. 5.
