RHI Magnesita proposed a GBp 551.00 per-share value for Vesuvius (ISIN GB00B82YXW83) on September 29, 2026, according to Investegate. The possible transaction remains the central issue for Vesuvius stock as the offer timetable approaches its next formal decision point.

Three dates define the offer

On June 29, 2026, Vesuvius rejected a proposal valued at GBp 550.00 per share, while the September 29, 2026 announcement described the latest structure at GBp 551.00, including GBp 470.00 in cash and 0.28 new RHI shares for every 10 Vesuvius shares, according to Investegate.

On October 23, 2026, Vanguard disclosed interests in 10,902,418 Vesuvius securities, equal to 4.39 percent, and reported a sale of 1,802 securities at GBP 4.46, according to the Financial Times.

What does the offer structure mean?

The headline value combines cash and equity rather than offering a cash-only exit. Vesuvius shareholders would receive approximately 7.1 million new RHI shares and own approximately 13 percent of the enlarged RHI share capital if the transaction completed, according to the company announcement carried by Investegate. The board is evaluating the financial terms and execution risk, so the proposal is not equivalent to a completed acquisition.

Two dates now matter

RHI Magnesita must announce a firm intention to make an offer or withdraw its interest by 5 p.m. London time on October 27, 2026. The date is set under Rule 2.6 of the Takeover Code, according to Investegate. A separate sales and revenue release for the third quarter of 2026 is listed for November 4, 2026 by MarketScreener.

Vesuvius stock faces a binary timetable

The next decisive information will concern the offer itself, not a routine earnings update. A firm offer could clarify the cash-and-share terms, while a withdrawal would return attention to Vesuvius's operating performance and the margin pressure visible in its first-half results.
