REG - Verition Fund Mgmt Vesuvius plc RHI Magnesita N.V. - Form 8.3 - VESUVIUS PLC

What happened

Verition Fund Management LLC filed a Form 8.3 public opening position disclosure on 26 October 2026, relating to Vesuvius Plc, with the position held or dealing undertaken as of 23 October 2026. The filing states Verition is also making disclosures in respect of RHI Magnesita NV.

Confirmed

Global impact / market context

A Form 8.3 disclosure is required under the Takeover Code, which means a person holding 1% or more of relevant securities must reveal interests during a takeover situation. This filing shows Verition holds or deals in Vesuvius shares, giving investors a signal about positions in a company under offer.

Analyst inference

The disclosure names both Vesuvius Plc and RHI Magnesita NV, pointing to a takeover or possible offer involving the two companies. Investors watching either company can use such filings to see how large holders are positioned as the situation develops, though the filing gives limited detail.

Analyst inference

What to watch

1. Verition filed Form 8.3 for Vesuvius Plc and stated it is also making disclosures in respect of RHI Magnesita NV, so further filings for that company may follow. Confirmed
2. Watch whether Verition submits additional disclosures showing changes in its Vesuvius or RHI Magnesita interests, which would indicate active dealing rather than a static opening position. Proposed
3. Monitor any offer documents or announcements from Vesuvius or RHI Magnesita, since formal offer terms would affect how these disclosed positions translate into investor outcomes. Analyst inference
