Trinseo PLC received notice from the New York Stock Exchange that it will begin delisting the company’s ordinary shares after Trinseo failed to meet the NYSE’s continued listing standard requiring at least a $15 million average market capitalization over 30 trading days.

The NYSE plans to file Form 25 with the SEC, and the delisting becomes effective 10 days after that filing. The company notes that this is not expected to affect its business operations, relationships with partners or employees, or SEC reporting.
Because Trinseo is an Irish company, once NYSE trading is suspended and the shares are delisted, transfers of ordinary shares will generally be subject to Irish stamp duty at 1% of the higher of purchase price or market value. DTC will stop clearing and settling trades and transfer positions to the company’s transfer agent, which may limit investors’ ability to trade unless they move holdings to another clearing agent or into direct registration. The company states its shares may trade on the OTC Pink Limited Market, but provides no assurance this will occur or continue, or that trading volume will support an efficient market.
