Vesuvius Surges Most Since 1990 After RHI Magnesita Cash-and-Shares Bid

The Quick Take

• Vesuvius Plc shares surged by their most since 1990 after receiving a cash-and-shares takeover bid from RHI Magnesita
• The deal would combine two leading metallurgical engineering and materials companies serving the global steel and metals industry
• The 1990-scale surge in Vesuvius stock highlights the significant premium RHI Magnesita is reportedly offering

Shares in Vesuvius Plc, the London-listed metallurgical engineering and refractory materials company, surged by their most since 1990 after the company confirmed it had received a cash-and-shares acquisition offer from RHI Magnesita, one of the world's largest refractory materials manufacturers. The deal, if completed, would create a dominant force in the global metallurgical consumables and high-temperature materials market, serving the steel, non-ferrous metals, and glass industries worldwide.

The proposed combination of Vesuvius and RHI Magnesita would create significant strategic synergies in a sector that is increasingly important to decarbonisation efforts. Refractory materials are critical to electric arc furnace (EAF) steelmaking — the low-carbon alternative to blast furnaces — whose adoption is accelerating globally as steel producers respond to emissions regulations. A combined entity would have pricing power and technical scale to supply the growing EAF buildout, particularly in Europe and India where green steel mandates are tightest.

Watch for formal bid terms and timing — a cash-and-shares structure suggests RHI Magnesita is managing its balance sheet while offering Vesuvius shareholders equity participation in the combined group. Key regulatory hurdles include competition review in the EU and UK, given both companies' significant market shares in European metallurgical supply chains. The macro variable is steel production volume and EAF transition pace, which determines the long-term revenue trajectory of the merged entity.
