In March 2024, ECHA published a registration update for trifluoroacetic acid (“TFA”). This update includes a self-classification, by TFA registrants, of a Category 2 Reproductive toxicant. BAuA, the German competent authority responsible for REACH and the CLP regulation in Germany, submitted a dossier to ECHA proposing to harmonize the hazard classification of TFA. In May 2025, ECHA launched a 60-day public consultation period on the CLH proposal for TFA which included updates to its hazard classification for reproductive toxicity, newly proposed as a category 1B, and introduced a PMT/vPvM (Persistent, Mobile and Toxic/very Persistent and very Mobile) classification. The public consultation period concluded and now ECHA’s Risk Assessment Committee ("RAC") is reviewing the dossier submitted by the German authority and the public comments received. RAC will develop an opinion, which should be submitted to the European Commission through the course of 2026. The EU Commission will then review RAC’s opinion and determine whether to proceed with the decision to amend the CLP regulation. If the Commission adopts the decision and amends Annex VI of the CLP Regulation, the changes become legally binding across the EU after a transition period. It should also be noted that there are other regulatory assessments underway from the European Food and Drug Agency ("EFSA") reviewing TFA which could impact timing of the CLH. The impacts of these various restrictions and regulatory measures in the EU as noted above, individually and in the aggregate, could lead to material adverse effects on our results of operations, financial condition, and cash flows.

In June 2026, ECHA’s RAC completed its scientific review and adopted an opinion recommending that TFA be classified as Reproductive Toxicity Category 1B, and as a PMT/vPvM substance under the EU CLP regulation. The recommendation is under consideration by the EU Commission and is not yet legally effective. If the Commission adopts the decision and amends Annex VI of the CLP Regulation, the changes become legally binding across the EU after a transition period. In July 2026, the European Food - Safety Authority completed published its updated scientific assessment of TFA. The revised guidance lowered the acceptable daily intake from its previous guidance and established a new acute reference dose. The impacts of these various restrictions, and regulatory measures and guidance in the EU as noted above, individually and in the aggregate, could lead to material adverse effects on our results of operations, financial condition, and cash flows.

Previous wording

In March 2023, EPA proposed a NPDWR to establish Maximum Contaminant Levels (MCL’s) for six PFAS, with PFOA and PFOS having MCLs as individual compounds (each proposed as 4 parts per trillion – (“ppt”)) and four other PFAS compounds, including HFPO Dimer Acid, having a hazard index approach limit on any mixture containing one or more of the compounds. The proposed PFAS NPDWR was subject to public comment through May 30, 2023, and on April 10, 2024 EPA issued its final rule, which included promulgating individual MCLs for PFOA and PFOS at 4ppt and individual MCLs for PFHxS, PFNA and HFPO Dimer Acid at 10ppt. In addition, EPA finalized a hazard index of 1 (unitless) as the MCL for any mixture of PFHxS, PFNA, HFPO Dimer Acid and PFBS. The final rule became effective 60 days from publication in the Federal Register and the compliance date for public water systems in the U.S. to meet the MCLs is five years from the publication date. In June 2024, we, as well as other organizations including the American Water Works Association and the American Chemistry Council, filed petitions for review of the final rule in the U.S. Court of Appeals for the D.C. Circuit. In May 2025, EPA announced that it intends to retain the MCLs for PFOS and PFOA, with rulemaking for additional time for compliance, and to rescind the other MCLs and hazard index. On September 11, 2025, EPA moved for partial vacatur of the regulation, requesting vacatur of its determination to regulate three individual compounds, including HFPO-DA, and mixtures of those compounds and another through a “hazard index”. EPA did not seek vacatur of the portions of the regulation governing PFOA and PFOS. Further briefing was ordered by the court, and was completed in March 2026. EPA has commenced the rulemaking process to rescind the Index PFAS portions of the 2024 MCLs regulation.
