May 18 (Reuters) - Shares in Advanced Medical Solutions AMSU.L fell as much as 24% on Monday, after private equity firm TA Associates confirmed it would not make an offer for the British medical supplier.

Here are some details:

• TA Associates did not provide a reason for walking away from the deal

• Advanced Medical Solutions, which develops and supplies wound‑care dressing technologies, said it remains confident in its standalone prospects and strategy

• In April, the firm said it was in negotiations with TA Associates over a potential takeover

• The company had attracted private equity interest in the past, including from Bridgepoint, according to media reports

• Analysts at Panmure Liberum said the failed approaches raise questions about why firms are unwilling to follow through on a deal, whether due to pricing disagreements or broader concerns about the business

• "It's not a good look, and inevitably, the market is going to worry about why PE don't want to pull the trigger on AMS" - Panmure Liberum

• Shares were down 20.2% at 197.2 pence at 0801 GMT

• Private equity interest in UK-listed companies is rising as firms look to capitalise on relatively low valuations
