The London Stock Exchange (LSE) faces a potentially devastating loss as mining giant Glencore reveals it is exploring the possibility of shifting its primary listing overseas. Glencore's departure would be the largest delisting in the LSE's history, given its £40bn market capitalization, making it the 16th largest company on the exchange, comparable in size to Barclays or National Grid.

Glencore, a leading producer of coal and copper ore, and one of the world's largest mining companies (second only to Rio Tinto on the LSE), announced this consideration after reporting a $1.6bn loss (£1.3bn) for 2024, a stark contrast to its $4.3bn (£3.4bn) net income in 2023. This downturn is attributed to impairments.

This news comes amid growing concerns about valuations for companies listed in London. Recent years have seen several high-profile companies, including Flutter and CRH, relocate their primary listings to New York. Furthermore, numerous companies seeking initial public offerings (IPOs) have bypassed London in favor of other exchanges, citing concerns about valuations, regulations, and visibility. Chip-maker ARM, payments platform Klarna, and Aspen Insurance are among those who have chosen New York over London for their listings. Even FTSE 100 construction rental firm Ashtead announced plans in December to shift its primary listing to New York. More recently, Unilever revealed that its ice cream business, including Ben & Jerry's and Magnum, will have its primary listing in Amsterdam upon its spin-off in 2025, with London only serving as an additional listing alongside New York.

Glencore CEO, Gary Nagle, told reporters after the annual results announcement that the company is evaluating whether other exchanges offer "better suited" trading conditions for its securities. "We want to ensure that our securities are traded on the right exchange, where we can get the right valuation," Nagle stated. "There have been questions raised previously around whether London is the right exchange. We’re looking at all relevant exchanges that would make sense for Glencore." He added, "London is one where we are and where we’re happy, but if there’s a better one, and those include the likes of the New York Stock Exchange, we have to consider that."

Glencore's shares have declined by 16% over the past year and roughly one-third since peaking above 500 pence in May 2023. They currently trade at 331 pence, down just over 6% on Wednesday following their morning financial report. Analysts at Deutsche Bank and Reuters suggest that weaker coal prices and the closure of a nickel operation in New Caledonia may be influencing investor sentiment towards Glencore, rather than the potential listing switch being the sole driver of the daily drop.
