Citi Nears Role as Lead Adviser as Rio Tinto-Weighed Bid for Glencore Advances

Citigroup Global Markets Inc. has been identified in London Stock Exchange filings as connected to Glencore Plc in relation to a possible approach by Rio Tinto, and people familiar with the matter say the bank is close to being engaged as Glencore's lead adviser. The move comes as advisors jockey for roles on a potential deal that could create a miner worth more than $200 billion, with key procedural deadlines under UK takeover rules approaching.

Key Points

  • Citigroup Global Markets Inc. filed disclosures linking it to Glencore in relation to a potential Rio Tinto approach; sources say Citi is close to becoming Glencore's lead adviser.
  • Rio Tinto and Glencore confirmed they were in early merger talks on January 8; the 28-day window under UK takeover rules currently expires on February 5, though extensions are possible.
  • Advisory roles on a deal of this scope are highly sought after, with potential advisory fees on the transaction estimated to exceed $100 million, affecting investment banking revenues and the mining sector.

Citigroup Global Markets Inc. has been flagged in filings on the London Stock Exchange as having a connection to Glencore Plc regarding a potential transaction with Rio Tinto, and two people familiar with the discussions said Citi is close to being appointed as Glencore's lead investment bank on a prospective takeover.

The disclosures were lodged with the UK Takeover Panel in January, identifying Citigroup as linked to Glencore in relation to a possible deal with Rio Tinto. Both the bank and Glencore declined to comment.

Those familiar with the situation said Citi has an established advisory relationship with Glencore, having worked on several of the miner-trader's major transactions in the past. That history includes advising on Glencore's 2011 initial public offering and more recently on its acquisition of Teck Resources' coal business.

Market participants have broadly expected Rio Tinto and Glencore - which on January 8 confirmed they were in early merger talks - might seek to extend the statutory window for a bidder to firm up an offer, given the potential transaction's scale and complexity. Under UK takeover rules, an identified potential bidder has 28 days to either announce a firm intention to make an offer or to cease the approach. The current 28-day period expires on February 5, though an extension can be sought by the parties.

Other investment banks are actively competing for advisory roles connected to any deal, the sources said, without naming those firms. Rio Tinto has already appointed advisers on its side - JP Morgan, Evercore and Macquarie - according to people aware of that development.

The advisory roles on a transaction of this size are highly prized within investment banking circles because they could generate substantial fees. People familiar with the matter have estimated advisory fees on a deal of this magnitude could exceed $100 million.


Context limitations - The parties involved have limited public comment, and the filings only indicate a connection between Citigroup and Glencore in relation to a possible deal with Rio Tinto. Sources described the near-term status of Citi's engagement and the broader advisory competition, but did not provide formal confirmations or detailed timetables beyond the existing regulatory deadlines.

Risks

  • Regulatory and procedural timing risk - UK takeover rules impose a 28-day period to announce or withdraw a firm offer, creating a short decision window unless parties request an extension; this affects deal momentum and planning in the mining sector and capital markets.
  • Deal complexity and scale - The potential transaction's magnitude could complicate negotiations and due diligence, introducing uncertainty for shareholders, advisers, and capital markets participants.
  • Advisory competition - Multiple banks are vying for roles on either side, which could affect fee outcomes and the composition of advisory teams, influencing investment banking fee pools and resource allocation.
