Trinseo PLC has entered into new debtor-in-possession and securitization financing to support operations during its Chapter 11 restructuring. The company’s subsidiaries signed an OpCo DIP Facility with a $270.0 million senior secured super-priority term loan and a Super-Holdco DIP Facility with a $157.5 million senior secured super-priority term loan, together providing $142.5 million of new money funding. The DIP loans carry cash interest at SOFR plus 9.00% for new money tranches and are secured by liens on substantially all borrower and guarantor assets, with super-priority administrative expense status. Trinseo also amended and restated its accounts receivable securitization program into a non-recourse revolving AR Facility of up to $150.0 million, collateralized by trade receivables from European and U.S. subsidiaries. These facilities include weekly-tested minimum liquidity and disbursement variance covenants and are intended to provide operating liquidity while the company pursues its prepackaged plan of reorganization.
Trinseo PLC has commenced voluntary Chapter 11 cases to implement a prepackaged restructuring that is expected to cut total debt by about $2.0 billion and annual interest expense by about $140 million. The company is operating as debtor‑in‑possession and has requested approval for a fully committed $158 million debtor‑in‑possession financing and a replacement receivables securitization program to provide day‑to‑day liquidity.
The plan, backed by holders of a significant majority of Trinseo’s debt, contemplates that existing lenders will receive substantially all of the equity in the reorganized company. Existing equity interests are expected to be cancelled with no recovery. By contrast, vendors and other general unsecured creditors are expected to be paid in full and remain unimpaired, allowing operations, customer service, and employee pay to continue in the ordinary course during the court process.
Trinseo PLC reports that counterparties under its Credit and Security Agreement for the accounts receivable securitization facility have extended the expiration date of an existing waiver to May 27, 2026. The company emphasizes that no new waiver agreement was signed; only the prior waiver’s term was extended.
The filing also notes that the company’s ordinary shares were delisted from the NYSE following a Form 25 filed on March 23, 2026, with the delisting effective March 30, 2026. Trinseo’s shares now trade over the counter under the symbol TSEOF.
Trinseo PLC has entered a Restructuring Support Agreement with a majority of its senior lenders to implement a pre-packaged Chapter 11 plan that will discharge and release approximately $2.0 billion of prepetition funded debt, cutting annual interest expense by about $140 million. Existing lenders are expected to receive 100% of the equity in the reorganized company, while current shareholders’ equity interests will be cancelled with no recovery. General unsecured claims, including trade creditors, vendors and suppliers, are expected to be treated as unimpaired, and the company plans to continue operating and paying employees and vendors in the ordinary course as debtors-in-possession. Trinseo also amended its super-priority revolving credit facility, adding a $25 million incremental revolving commitment that was fully drawn on May 13, 2026, and highlighted additional committed financing including about $158 million of debtor-in-possession financing and a $150 million accounts receivable facility.
Trinseo PLC disclosed that lenders have extended the expiration dates of several previously granted waivers tied to its debt facilities. The waiver under its super-priority revolving credit facility, the waiver under its 2017 senior credit agreement, and the waiver under its 2023 refinance credit agreement now all run until May 13, 2026. A separate waiver under the 2024 credit and security agreement for the company’s accounts receivable securitization facility has been extended until May 14, 2026. No new waiver agreements were signed; the existing waivers were simply prolonged under their original terms as part of Trinseo’s ongoing capital structure discussions and restructuring efforts.
Trinseo PLC reported weaker first quarter 2026 results, with net sales of $724.7 million, down 8% from the prior year as lower prices and volumes more than offset favorable currency effects. The company recorded a net loss of $115.9 million, compared with a $79.0 million loss a year earlier, as higher interest expense and restructuring-related costs weighed on results.
Adjusted EBITDA was $52.6 million, down from $64.8 million, reflecting the absence of prior-year technology licensing income, partly offset by savings from restructuring actions. Cash used in operating activities was $232.9 million, and together with capital expenditures this led to Free Cash Flow of negative $244.2 million, driven by seasonality, tighter trade credit and higher raw material costs. The balance sheet shows cash and cash equivalents of $110.6 million and shareholders’ deficit of $1.22 billion as of March 31, 2026.
Trinseo PLC reports that it and certain subsidiaries chose not to make scheduled interest payments under several credit facilities, including approximately $38 million due under a 2023 credit agreement. Once grace periods expire, these missed payments constitute events of default under certain debt agreements.
The company has obtained amendments and limited waivers from requisite lenders that temporarily suspend certain acceleration and collateral enforcement rights and remedies until April 30, 2026. Second‑lien secured notes bearing 7.625% interest and maturing in 2029 are subject to an intercreditor agreement that blocks collateral enforcement by those noteholders for 180 days after any acceleration, and no acceleration of those notes has been declared. Trinseo is continuing capital structure discussions with financial stakeholders and warns there is no assurance any restructuring transaction will be agreed or completed.
Trinseo PLC reports new steps in its ongoing capital structure negotiations and debt management efforts. Subsidiaries entered a Securitization Waiver on April 10, 2026 that extends the temporary limited waiver of acceleration and collateral enforcement rights under the Accounts Receivable Securitization Facility to April 30, 2026, reduces the advance rate from 92.5% to 90%, and adds a 0.25% structuring fee on revolving commitments. The company also executed a Second Amendment to its SuperPriority Revolver, creating a $50,000,000 2026 Incremental Revolving Facility maturing February 2, 2028. Trinseo borrowed $10,400,000 at closing, with interest payable in kind at Term SOFR plus 9.00% or an alternate base rate plus 8.00%, along with a 0.375% unused line fee and a 3.50% closing fee. The filing follows the March 30, 2026 delisting of its ordinary shares from the NYSE; they now trade over the counter under the symbol TSEOF, and the company intends to continue discussions with financial stakeholders.
Trinseo PLC outlines a series of credit agreement amendments and temporary waivers after missing certain interest and principal payments beyond contractual grace periods. Lenders under its super-priority revolving credit facility removed anti-cash hoarding provisions and a minimum liquidity covenant, and agreed to a limited waiver of acceleration and collateral enforcement rights until April 30, 2026, in exchange for an in‑kind consent fee of 1.00% of each lender’s commitments.
Similar limited waivers under the Senior Credit Agreement and the Refinance Credit Agreement also run through April 30, 2026, with an additional 1.00% in‑kind consent fee on each participating lender’s outstanding loans under the refinance facility. A separate securitization waiver under the accounts receivable facility extends only until April 2, 2026. The company continues discussions with financial stakeholders on restructuring its capital structure, while noting that the New York Stock Exchange has begun delisting proceedings for its ordinary shares.
Trinseo PLC reports that several subsidiaries have entered into amendments and limited waivers with lenders under its super-priority revolver, senior and refinance credit agreements, and accounts receivable securitization facility. These waivers temporarily restrict lenders from accelerating debt or enforcing collateral remedies into late April 2026.
On March 19, 2026, Trinseo-related entities elected not to make scheduled interest payments of approximately $10 million under the 2L Notes Indenture and approximately $12 million under the Senior Credit Agreement after contractual grace periods lapsed. These non-payments are events of default and trigger cross-defaults across multiple facilities, though no accelerations have yet been declared. The filing also notes that the New York Stock Exchange has commenced proceedings to delist Trinseo’s ordinary shares, underscoring the company’s heightened financial stress as it continues capital structure negotiations.
Trinseo PLC reported weaker results for the fourth quarter and full year 2025. Fourth quarter net sales were $663 million, down 19% from 2024, with a net loss of $251 million versus $118 million a year earlier. The quarter included $127 million of pre-tax restructuring and other charges, while Adjusted EBITDA held roughly flat at $26 million.
For 2025, net sales were $2,974.9 million, down about 15%, and the full-year net loss widened to $545.6 million from $348.5 million. Full-year Adjusted EBITDA declined to $162.5 million from $203.7 million. Free Cash Flow was negative $153.4 million, reflecting cash used in operations of $102.4 million and capital expenditures of $51.0 million.
At December 31, 2025, Trinseo had cash and cash equivalents of $146.7 million and long-term debt of $2,332.5 million. Shareholders’ equity was a deficit of $1,097.8 million, deeper than the prior year’s deficit. Management highlighted ongoing restructuring actions, cost savings efforts and investment in strategic growth areas, while noting multiple risks including high indebtedness and going concern uncertainties in its risk discussion.
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. Trading in the shares was suspended immediately.
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.
Trinseo PLC amended its Credit Agreement through subsidiaries on February 16, 2026 to extend, until March 19, 2026, the grace period for interest payments due between February 1 and March 1, 2026. This extension is designed to match the grace period available under its second‑lien notes.
Separately, a Trinseo subsidiary elected to use a 30‑day contractual grace period on an approximately $10.0 million interest payment due February 17, 2026 on its 7.625% second lien secured notes due 2029. The company states it has sufficient cash to pay but chose to delay while it continues ongoing discussions with financial stakeholders regarding its capital structure, retaining the right to pay within the grace period before any event of default is triggered.
Trinseo PLC reported that its Board of Directors voted on January 16, 2026 to expand the board from ten to eleven members and appointed two new independent directors, Carol Flaton and Jill Frizzley, effective immediately.
The company highlights their deep experience in banking, finance, restructuring, governance, strategic transactions, and business transformations, noting this is relevant to ongoing discussions with financial stakeholders about Trinseo's capital structure. Flaton currently serves on the board of QVC Group, Inc., while Frizzley is president of Wildrose Partners LLC and serves on the board of LanzaTechGlobal, Inc.
Under amended consulting agreements dated January 12, 2026, each will receive a $50,000 monthly fee for board service, and the usual director compensation program is suspended for them. Both are covered by Trinseo's standard indemnification agreement, and the company states there are no related-party transactions or special arrangements tied to their selection.
Trinseo PLC approved one-time conditional cash retention bonuses for its named executive officers. The Compensation Committee granted awards of $3,200,000 to President and CEO Frank Bozich, $2,500,000 to Executive Vice President and CFO David Stasse, $1,700,000 to Senior Vice President Francesca Reverberi, $1,350,000 to Senior Vice President and Chief Legal Officer Angelo Chaclas, and $1,000,000 to Senior Vice President and Chief Human Resources Officer Paula Cooney. These retention awards were paid on or about January 8, 2026 and are conditioned on each executive remaining employed through March 31, 2027, except in the case of a defined Qualifying Termination, or else the awards must be fully repaid to the company.
Trinseo PLC received a notice from the New York Stock Exchange that it no longer meets two continued listing standards covering minimum market capitalization and minimum share price.
The NYSE cited a 30 trading‑day average global market capitalization of approximately $35.6 million as of December 11, 2025 and a stockholders’ deficit of approximately ($861.6) million as of September 30, 2025, both below the $50 million thresholds.
The company’s ordinary shares also averaged below the $1.00 minimum, with a 30 trading‑day average closing price of $0.99, triggering a six‑month share price cure period and an 18‑month market capitalization cure period, during which Trinseo plans to submit and follow an NYSE compliance plan.
Its shares will continue trading on the NYSE with a “.BC” indicator during the cure periods, and the notice does not change its ongoing business operations or SEC reporting obligations.
Trinseo PLC approved a restructuring plan to permanently close its polystyrene production operations in Schkopau, Germany and consolidate remaining polystyrene operations in Tessenderlo, Belgium. The company expects to record total pre-tax restructuring charges of $30 million to $40 million, including $3 million to $5 million of employee-related costs, $10 million to $14 million of asset-related charges, and $15 million to $21 million tied to exiting production activities such as contract terminations, demolition and decommissioning. Future cash payments related to these charges are estimated at $18 million to $24 million, with substantially all payments expected by the end of 2028. Actions under the plan are expected to begin in the fourth quarter of 2025 and be completed by the end of 2028, subject to local law requirements and negotiations with works councils and other stakeholders. The company estimates these initiatives will deliver about $10 million of annualized profitability improvement beginning in 2026.
Trinseo PLC (TSE) furnished a press release announcing its financial results for the third quarter and year ended September 30, 2025, and will host an investor call and webcast on November 7, 2025 at 10:30 AM Eastern Time to discuss the results. The company also made an investor presentation available on its website. The press release is furnished as Exhibit 99.1 and the investor presentation as Exhibit 99.2.
Trinseo PLC approved a restructuring plan to permanently close its methyl methacrylate (MMA) plant in Rho and acetone cyanohydrin (ACH) operations in Porto Marghera, Italy. The plan is meant to streamline its MMA production network, with the company sourcing all MMA feedstock from third-party producers.
Trinseo expects total pre-tax restructuring charges of $80 million to $100 million, including $3 million to $6 million of employee-related costs, $40 million to $46 million of asset-related charges, and $37 million to $48 million tied to exiting production activities such as contract terminations, demolition and decommissioning. Future cash payments are projected at $40 million to $50 million, mostly by the end of 2028, with actions beginning in Q4 2025 and targeted completion by the end of 2026, subject to local law. The company estimates about $20 million of annualized profitability improvement starting in 2026. In the same press release, the Board also disclosed that it has voted to indefinitely suspend the quarterly dividend.
Trinseo PLC disclosed that its Board of Directors has voted to indefinitely suspend the company’s quarterly dividend of $0.01 per share. This means shareholders will no longer receive the small recurring cash payment that had been made each quarter.
The company expects this suspension to save approximately $1.5 million annually. Ending the dividend reduces cash outflows and preserves capital within the business, but also removes a source of regular income for shareholders who relied on these payments.
Trinseo PLC furnished an update describing the composition of its trade volumes by business segment and end application. The company released this supplemental information on August 26, 2025 to help investors better understand demand trends across the different end uses for its products.
The details are provided in Exhibit 99.1, which breaks down trade volumes by segment and end application. This information is being furnished under Regulation FD, meaning it is not deemed filed for purposes of certain liability provisions of the securities laws and is not automatically incorporated into other securities filings unless specifically referenced.
