Previous wording

Our costs to comply with complex environmental laws and regulations, as well as internal and external voluntary programs, are significant and will continue to be significant for the foreseeable future. These laws and regulations may change and could become more stringent over time, which could result in significant additional compliance costs, increased costs of purchased energy or other raw materials, increased transportation costs, investments in, or restrictions on, our operations, installation or modification of emission control equipment, or additional costs associated with emissions control equipment. Additionally, to the extent these laws, regulations and restrictions are not stringently imposed in the countries in which our competitors operate, our competitors could gain cost or other competitive advantages. As a result of our current and historic operations, including the operations of divested businesses and certain discontinued operations, we also expect to continue to incur costs for environmental investigation and remediation activities at a number of our current or former sites and third-party disposal locations. However, the ultimate costs under environmental laws and the timing of these costs are difficult to accurately predict. While we establish accruals in accordance with U.S. generally accepted accounting principles (“GAAP”), the ultimate actual costs and liabilities may vary from the accruals because the estimates on which the accruals are based depend on a number of factors (many of which are outside of our control), including the nature of the matter and any associated third-party claims, the complexity of the site, site geology, the nature and extent of contamination, the type of remedy, the outcome of discussions with regulatory agencies and other Potentially Responsible Parties (“PRPs”) at multi-party sites, and the number and financial viability of other PRPs. We also could incur significant additional costs as a result of additional contamination that is discovered or remedial obligations imposed in the future. Refer to “Environmental Matters” within Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations and “Note 17 – Commitments and Contingent Liabilities” to the Interim Consolidated Financial Statements for further information.

Previous wording

In May 2020, five European countries began an initiative to restrict the manufacture, placing on the market and use of PFAS in the EU. In this regulatory process, more than 4,000 substances, including F-gases and fluoropolymers are being considered for potential broad regulatory action. On July 15, 2021, the countries submitted their restriction proposal, which informed ECHA of the intent to prepare a PFAS restriction dossier for fluorinated substances within a defined structural formula scope, including branched fluoroalkyl groups and substances containing ether linkages, fluoropolymers and side chain fluorinated polymers. The restriction dossier was submitted to ECHA in January 2023, and in February 2023 ECHA published a report and supporting annexes on the restriction proposal, which includes identified concerns for in-scope PFAS and their degradation products and the proposed restriction of a full ban with certain use-specific time-limited derogation periods. Comments were submitted from individuals and organizations during the consultation period in 2023 and the restriction dossier is being reviewed by the ECHA Risk Assessment Committee ("RAC") and Socio-economic Analysis Committees (“SEAC”). RAC and SEAC are focusing on the different sectors that are affected and elements of the proposal, and further meetings were held in 2025. In August 2025, the five national authorities reviewed over 5,600 comments from the 2023 consultation and updated their original restriction proposal. This revised version, called the Background Document, is now the basis for ECHA’s committee opinions and includes alternative restriction options instead of a full ban or a ban with time-limited derogations for certain applications. The document may still be updated further as the committees continue their evaluation. The RAC and SEAC are expected to complete their scientific evaluation by the end of 2026, which marks the end of the regulatory phase, and the file moves to the European Commission and initiates the start of the political phase. The estimated earliest entry into force of restrictions is 2027, contingent upon timely completion of the remaining steps in the EU REACH restriction process.

Previous wording

In January 2024, the European Council adopted a regulation supporting the phase down of hydrofluorocarbons (“HFC”) by 2050 and multiple bans on HFCs and hydrofluoroolefin (“HFO”) in select applications. The new regulation entered into force on March 11, 2024, and includes both reviews and exemptions. No later than January 1, 2030, the European Commission will publish a report on the effects of the regulation and whether the bans are upheld based on technical feasibility and socioeconomic impact of alternatives. Also in 2024, Regulation (EU) 2024/573 was published and became effective, with a later implementing regulation ((EU) 2024/2473), that changed rules governing F-Gas reporting and quota consumption. In preparing its 2024 F-Gas reporting submissions, we encountered uncertainty on how to report due to impacts from the implementation of the new regulation in the reporting portal as well as technical challenges associated therewith. We raised these reporting concerns with the competent authorities and resources and are continuing to evaluate the potential impact of these new F-Gas reporting and quota consumption regulations on us.

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. 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.

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, and a hearing is scheduled in September 2026 on the review petitions. EPA has commenced the rulemaking process to rescind the Index PFAS portions of the 2024 MCLs regulation.
