Vesuvius shares slump as temporary "operational issues" weigh on trade

Shares in Vesuvius PLC on Monday plunged as it forecast 2026 trading profit below current market expectations.

The London-based molten metal flow engineering and technology company said that since its May trading update, it has continued to be hurt by "operational issues" in its Steel division. Additionally, Advanced Refractories is experiencing a "challenging" trading environment, particularly in Europe.

"The operational issues, whilst temporary, are causing a greater impact than previously anticipated," Vesuvius said. The issues are being addressed and are expected to be resolved by the end of the year, it added. The company didn't specify what the operational issues are.

Vesuvius now expects full-year trading profit to be slightly ahead of £151.1 million in 2025, on a constant currency basis, below the £169 million market consensus, cited by JPMorgan. Trading profit for the first half of 2026 is expected to be around £74 million, down from £79.0 million in the first half of 2025.

Shares in Vesuvius fell 9.8% to 407.80 pence each in London on Monday morning, the worst performing stock in the FTSE 250 index, which was up 0.6%.
