H.B. Fuller confirms all-cash proposal, currently conducting due diligence with AMS

AMS shares surge up to 13.5% after news, market cap peaks at £528.6 million

H.B. Fuller has until June 18 to make firm offer under UK rules

May 21 (Reuters) - British medical supplier Advanced Medical Solutions AMSU.L on Thursday said it had received an unsolicited takeover proposal from U.S.-based adhesives maker H.B. Fuller FUL.N, days after its buyout talks with a private-equity firm ended.

Shares of the British company rose as much as 13.5% to 240 pence, giving it a market capitalisation of £528.6 million ($710.02 million).

Minnesota-based specialty chemicals company H.B. Fuller said it submitted an all-cash proposal for AMS on April 30.

Neither side disclosed financial details of the proposed bid.

H.B. Fuller said it was engaged in due diligence with the British company.

The approach, which is the second bid in just over a month for the London-listed company, comes days after private equity firm TA Associates walked away from deal talks without giving a reason or a bid value.

AMS, which develops and supplies wound‑care dressing technologies, would strengthen H.B. Fuller's push into high-margin medical adhesives and wound‑care products, diversifying its revenue stream.

AMS stock was last up 5.9% at 224 pence.

This approach is the latest in a series of bids for London-listed companies as overseas firms seek to take advantage of relatively low UK equity valuations.

H.B. Fuller has until June 18 to announce a firm intention to make an offer or walk away under UK takeover rules.
