H.B. Fuller Co. submitted an all‑cash offer exceeding £600 million ($804 million) for Advanced Medical Solutions Group Plc.
The proposal values AMS at over 280 pence per share, representing a premium of more than 30% to the prior closing price.
Under UK takeover rules, H.B. Fuller must firm the bid or withdraw by June 18, though no binding offer is certain.
Goldman Sachs and Perella Weinberg advise H.B. Fuller, while AMS is advised by Evercore and Investec as negotiations continue.
