<div id="readability-page-1"><div>Fitch Ratings-São Paulo-26 November 2025:Fitch Ratings downgraded Braskem Idesa SAPI's Long-Term Local and Foreign Currency Issuer Default Ratings (IDRs) to 'RD' from 'C'. Fitch also affirmed Braskem Idesa's senior secured bonds at 'C' with a Recovery Rating of 'RR4'.The rating action follows the company's failure to cure the missed interest payment due Nov. 18, 2025 on its senior secured notes during the company's ongoing negotiations with creditors. The 'RD' rating applies to an issuer that has an uncured payment default but has not filed for bankruptcy or ceased operations.Key Rating DriversUncured Missed Interest Payment: Braskem Idesa skipped an interest payment due on Nov. 18, 2025 on its USD900 million senior secured notes. Fitch assesses the failure to cure the missed interest payment within the original five-day grace period as a Restricted Default under its rating definitions.Possible Debt Restructuring: Braskem Idesa announced on Sept. 8, 2025 that it had hired a financial advisor to evaluate financial alternatives for its strained liquidity and capital structure. The company may enter a debt restructuring process in the near to medium term.Peer AnalysisBraskem Idesa's ratings reflect the non-payment of bond interest after the original five-day grace period.Recovery AnalysisThe recovery analysis for Braskem Idesa assumes a liquidation approach to valuation.Liquidation Approach Inputs:-- MXN1,700 million of inventory valued at 50%;-- MXN29,400 million of PP&amp;E valued at 50%;-- Total liquidation value USD31,240 million;-- A 10% administrative claim.With these assumptions, Fitch's Waterfall-Generated recovery Computation (WGRC) for the senior secured notes indicates an 'RR3' band. However, according to Fitch's Country-Specific Treatment of Recovery Ratings criteria, the Recovery Rating for corporate issuers in Mexico is capped at 'RR4'.RATING SENSITIVITIESFactors that Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade:--Filing for bankruptcy protection would result in a downgrade to 'D'.Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade:--Fitch will reassess the IDRs after the completion of the debt restructuring; updated IDRs will reflect the issuer's new capital structure and credit profile.Issuer ProfileBraskem Idesa, S.A.P.I. is a polyethylene producer with operations in the city of Coatzacoalcos, Mexico.

In issuing and maintaining its ratings and in making other reports (including forecast information), Fitch relies on factual information it receives from issuers and underwriters and from other sources Fitch believes to be credible. Fitch conducts a reasonable investigation of the factual information relied upon by it in accordance with its ratings methodology, and obtains reasonable verification of that information from independent sources, to the extent such sources are available for a given security or in a given jurisdiction. The manner of Fitch’s factual investigation and the scope of the third-party verification it obtains will vary depending on the nature of the rated security and its issuer, the requirements and practices in the jurisdiction in which the rated security is offered and sold and/or the issuer is located, the availability and nature of relevant public information, access to the management of the issuer and its advisers, the availability of pre-existing third-party verifications such as audit reports, agreed-upon procedures letters, appraisals, actuarial reports, engineering reports, legal opinions and other reports provided by third parties, the availability of independent and competent third- party verification sources with respect to the particular security or in the particular jurisdiction of the issuer, and a variety of other factors. Users of Fitch’s ratings and reports should understand that neither an enhanced factual investigation nor any third-party verification can ensure that all of the information Fitch relies on in connection with a rating or a report will be accurate and complete. Ultimately, the issuer and its advisers are responsible for the accuracy of the information they provide to Fitch and to the market in offering documents and other reports. In issuing its ratings and its reports, Fitch must rely on the work of experts, including independent auditors with respect to financial statements and attorneys with respect to legal and tax matters. Further, ratings and forecasts of financial and other information are inherently forward-looking and embody assumptions and predictions about future events that by their nature cannot be verified as facts. As a result, despite any verification of current facts, ratings and forecasts can be affected by future events or conditions that were not anticipated at the time a rating or forecast was issued or affirmed.The information in this report is provided “as is” without any representation or warranty of any kind, and Fitch does not represent or warrant that the report or any of its contents will meet any of the requirements of a recipient of the report. A Fitch rating is an opinion as to the creditworthiness of a security. This opinion and reports made by Fitch are based on established criteria and methodologies that Fitch is continuously evaluating and updating. Therefore, ratings and reports are the collective work product of Fitch and no individual, or group of individuals, is solely responsible for a rating or a report. The rating does not address the risk of loss due to risks other than credit risk, unless such risk is specifically mentioned. Fitch is not engaged in the offer or sale of any security. All Fitch reports have shared authorship. Individuals identified in a Fitch report were involved in, but are not solely responsible for, the opinions stated therein. The individuals are named for contact purposes only. A report providing a Fitch rating is neither a prospectus nor a substitute for the information assembled, verified and presented to investors by the issuer and its agents in connection with the sale of the securities. Ratings may be changed or withdrawn at any time for any reason in the sole discretion of Fitch. Fitch does not provide investment advice of any sort. Ratings are not a recommendation to buy, sell, or hold any security. Ratings do not comment on the adequacy of market price, the suitability of any security for a particular investor, or the tax-exempt nature or taxability of payments made in respect to any security. Fitch receives fees from issuers, insurers, guarantors, other obligors, and underwriters for rating securities. Such fees generally vary from US$1,000 to US$750,000 (or the applicable currency equivalent) per issue. In certain cases, Fitch will rate all or a number of issues issued by a particular issuer, or insured or guaranteed by a particular insurer or guarantor, for a single annual fee. Such fees are expected to vary from US$10,000 to US$1,500,000 (or the applicable currency equivalent). The assignment, publication, or dissemination of a rating by Fitch shall not constitute a consent by Fitch to use its name as an expert in connection with any registration statement filed under the United States securities laws, the Financial Services and Markets Act of 2000 of the United Kingdom, or the securities laws of any particular jurisdiction.
