Trinseo PLC reported that on August 7, 2026, a standalone calculation showed its net assets are half or less of its called-up share capital. Under Section 1111 of the Irish Companies Act 2014, this requires the board to convene an extraordinary general meeting to consider what measures, if any, should be taken.
The company mailed notice on August 14, 2026 to shareholders of record as of August 12, 2026, calling an Extraordinary General Meeting on September 23, 2026 at its Wayne, Pennsylvania offices, with audio/video participation available in Dublin. The meeting’s stated purpose is discussion only; no resolutions or shareholder votes will be presented.
Trinseo PLC reported second quarter 2026 net sales of $845 million, up 8% from a year earlier, as higher prices and favorable currency offset volume declines from closing virgin MMA production in Italy and a force majeure outage at the Tessenderlo polystyrene plant. Net loss was $120 million, $14 million worse than prior year, including $89 million of pre-tax charges tied to reorganization, debt restructuring and asset programs.
Adjusted EBITDA rose to $81.0 million from $41.6 million, mainly from margin improvements in Polymer Solutions and Engineered Materials and savings from earlier restructuring actions. However, cash used in operating activities was $115.3 million and Free Cash Flow was negative $125.3 million, pressured by $85 million of debt and other restructuring fees and an $80 million working capital increase.
At June 30, 2026, total assets were $2,498.6 million, liabilities subject to compromise were $2,562.3 million, and shareholders’ equity showed a deficit of $1,347.2 million, reflecting court-supervised financial restructuring supported by a DIP Facility. Management highlights ongoing efforts to complete a balance sheet restructuring and enhance long-term financial flexibility.
Trinseo PLC plans to hold its annual general meeting of shareholders on September 23, 2026 at 8:30 a.m. EST. Shareholders of record as of July 30, 2026 will be entitled to participate.
The meeting will take place at the company’s headquarters at 440 East Swedesford Road, Suite 301, Wayne, Pennsylvania 19087, with shareholders in Ireland able to join via audio and video link at McCann FitzGerald LLP in Dublin. Shareholders who plan to attend must register in advance, with further details to be provided in the company’s proxy statement.
