The Company and certain subsidiaries are involved in various lawsuits, claims and environmental actions that have arisen in the normal course of business with respect to product liability, patent infringement, governmental regulation, contract and commercial litigation, as well as possible obligations to investigate and mitigate the effects on the environment of the disposal or release of certain substances at various sites. In addition, in connection with divestitures and the related transactions, the Company from time to time has indemnified and has been indemnified by third parties against certain liabilities that may arise in connection with, among other things, business activities prior to the completion of the respective transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. The Company records liabilities for ongoing and indemnification matters when the information available indicates that it is probable that a liability will be incurred and the amount of the loss can be reasonably estimated.

As of March 31, 2024, the Company has recorded indemnification assets of $26 million within "Accounts and notes receivable - net" and $284 million within "Deferred charges and other assets" and indemnification liabilities of $178 million within "Accrued and other current liabilities" and $238 million within "Other noncurrent obligations" within the interim Condensed Consolidated Balance Sheets. As of December 31, 2023, the Company has recorded indemnification assets of $21 million within "Accounts and notes receivable - net" and $242 million within "Deferred charges and other assets" and indemnified liabilities of $200 million within "Accrued and other current liabilities" and $263 million within "Other noncurrent obligations" within the interim Condensed Consolidated Balance Sheets.

The Company’s accruals for indemnification liabilities related to the binding Memorandum of Understanding (“MOU”) between Chemours, Corteva, EIDP and the Company and to the DowDuPont ("DWDP") Separation and Distribution Agreement and the Letter Agreement between the Company and Corteva (together the “Agreements”) discussed below, are included in the balances above. Additionally, as of March 31, 2024, the Company has recognized a liability of $408 million (including interest) related to the settlement agreement between Chemours, Corteva, EIDP and DuPont related to the aqueous film-forming foams multi-district litigation, as discussed below.

On July 1, 2015, EIDP, a Corteva subsidiary since June 1, 2019, completed the separation of EIDP’s Performance Chemicals segment through the spin-off of Chemours to holders of EIDP common stock (the “Chemours Separation”). On June 1, 2019, the Company completed the separation of its agriculture business through the spin-off of Corteva, including Corteva’s subsidiary EIDP.

On January 22, 2021, the Company, Corteva, EIDP and Chemours entered into the MOU pursuant to which the parties have agreed to release certain claims that had been raised by Chemours including any claims arising out of or resulting from the process and manner in which EIDP structured or conducted the Chemours Separation, and any other claims that challenge the Chemours Separation or the assumption of Chemours Liabilities (as defined in the Chemours Separation Agreement) by Chemours and the allocation thereof, subject in each case to certain exceptions set forth in the MOU.

Pursuant to the MOU, the parties have agreed to share certain costs associated with potential future liabilities related to alleged historical releases of certain PFAS out of pre-July 1, 2015 conduct (“eligible PFAS costs”) until the earlier to occur of (i) December 31, 2040, (ii) the day on which the aggregate amount of Qualified Spend, as defined in the MOU, is equal to $4 billion or (iii) a termination in accordance with the terms of the MOU. PFAS refers to per- or polyfluoroalkyl substances, which include perfluorooctanoic acids and its ammonium salts (“PFOA”).

The parties have agreed that, during the term of this sharing arrangement, Qualified Spend up to $4 billion will be borne 50 percent by Chemours and 50 percent, up to a cap of $2 billion, by the Company and Corteva. The Company and Corteva will split their 50 percent of Qualified Spend in accordance with the Agreements; accordingly, the Company's portion of the $2 billion is approximately $1.4 billion. At March 31, 2024, the Company had paid Qualified Spend of approximately $175 million against its portion of the $2 billion cap. After the term of this arrangement, Chemours’ indemnification obligations under the Chemours Separation Agreement would continue unchanged.

In order to support and manage any potential future eligible PFAS costs, the parties also agreed to establish an escrow account, (the "MOU Escrow Account"). The MOU provides that (1) no later than each of September 30, 2021 and September 30, 2022, Chemours shall deposit $100 million and DuPont and Corteva shall together deposit $100 million in the aggregate into the MOU Escrow Account and (2) no later than September 30 of each subsequent year through and including 2028, Chemours shall deposit $50 million and DuPont and Corteva shall together deposit $50 million in the aggregate into the MOU Escrow Account. Subject to the terms and conditions set forth in the MOU, each party may be permitted to defer funding in any calendar year

beginning with 2022 through and including 2028. Additionally, if on December 31, 2028, the balance in the MOU Escrow Account (including interest) is less than $700 million, Chemours will make 50 percent of the deposits and DuPont and Corteva together will make 50 percent of the deposits necessary to restore the balance to $700 million. Such payments will be made in a series of consecutive annual equal installments commencing on September 30, 2029 pursuant to the replenishment terms set forth in the MOU.

Under the Agreements, Divested Operations and Businesses ("DDOB") liabilities of EIDP not allocated to or retained by Corteva or the Company are categorized as relating to either (i) PFAS Stray Liabilities, if they arise out of actions related to or resulting from the development, testing, manufacture or sale of PFAS; or (ii) Non-PFAS Stray Liabilities, (and together with PFAS Stray Liabilities, the “EIDP Stray Liabilities”).

The Agreements provide that the Company and Corteva will each bear a certain percentage of the Indemnifiable Losses, described below, rising from EIDP Stray Liabilities and that the percentage changes upon each company meeting its respective threshold of $150 million for PFAS Stray Liabilities and $200 million for EIDP Stray Liabilities. In addition, for certain Non-PFAS Liabilities, (“Specified Spend Non-PFAS Liabilities”), Corteva must spend specified amounts before costs associated with such matter will be considered Indemnifiable Losses.

The Agreements provide that the Company and Corteva each bear 50 percent of the first $300 million ($150 million) of total Indemnifiable Losses related to PFAS Stray Liabilities. In 2023, the companies met their respective $150 million threshold and as a result the Company bears 71 percent of Indemnifiable Losses related to PFAS Stray Liabilities and Corteva bears 29 percent. At March 31, 2024, DuPont has accrued for future Qualified Spend and Indemnifiable Losses related to PFAS Stray Liabilities accordingly.

The $150 million of Indemnifiable Losses incurred for PFAS Stray Liabilities has been credited against each company’s $200 million threshold. Corteva has met its $200 million threshold. As a result, until the Company meets its $200 million threshold, it is responsible for managing the Non-PFAS Stray Liabilities, excluding Specified Spend Non-PFAS Liabilities for which Corteva has not reached its specified spend amount, and is bearing all Indemnifiable Losses associated with such Non-PFAS Stray Liabilities. Thereafter, DuPont will bear 71 percent and Corteva will bear 29 percent of Indemnifiable Losses related to Non-PFAS Stray Liabilities. At March 31, 2024, the Company has accrued for future Indemnifiable Losses related to Non-PFAS Stray Liabilities, including Specified Spend Non-PFAS Liabilities, accordingly.

Indemnifiable Losses, as defined in the DWDP Separation and Distribution Agreement, include, among other things, attorneys’, accountants’, consultants’ and other professionals’ fees and expenses incurred in the investigation or defense of EIDP Stray Liabilities.


Indemnification Related Liabilities Associated with the MOU

Current indemnification liabilities	$	88	$	87	Accrued and other current liabilities
Long-term indemnification liabilities	123		119		Other noncurrent obligations
Total indemnification liabilities accrued under the MOU 1	$	211	$	206

1.As of March 31, 2024 and December 31, 2023, total indemnified liabilities accrued include $136 million and $139 million, respectively, related to Chemours environmental remediation activities at their site in Fayetteville, North Carolina under the Consent Order between Chemours and the North Carolina Department of Environmental Quality (the "NC DEQ"). This excludes amounts related to the Water District Settlement Agreement, as defined below.

In addition to the above, beginning the second quarter of 2023 and as of March 31, 2024, the Company has recognized a liability related to the Water District Settlement Agreement, defined below, between Chemours, Corteva, EIDP and DuPont related to the aqueous film-forming foams multi-district litigation. As of March 31, 2024, the liability recognized by the Company related to the Water District Settlement Agreement is $408 million, including interest.

Under EIDP’s 2004 settlement of a West Virginia state court class action, Leach v.EIDP , members of the class have standing to pursue personal injury claims for just six health conditions that an expert panel appointed under the Leach settlement reported in 2012 had a “probable link” (as defined in the settlement) with PFOA: pregnancy-induced hypertension, including preeclampsia; kidney cancer; testicular cancer; thyroid disease; ulcerative colitis; and diagnosed high cholesterol. After the panel reported its findings, approximately 3,550 personal injury lawsuits filed in Ohio and West Virginia state and federal courts , were consolidated in multi-district litigation in the U.S. District Court for the Southern District of Ohio (“Ohio MDL”). In 2017, Chemours and EIDP settled the Ohio MDL for $670 million.

Post the 2017 settlement, approximately 100 additional cases were filed by Leach class members. EIDP and Chemours settled all but one these cases in 2021 for $83 million with each of the Company and EIDP contributing $27 million and Chemours contributing $29 million. The 2021 settlement was entered solely by way of compromise and settlement and is not in any way an admission of liability or fault by the Company, Corteva, EIDP or Chemours. The remaining case resulted in a jury verdict for the plaintiff. The Company paid its share in accordance with the Agreements and MOU in the fourth quarter 2023 after EIDP had exhausted its appeal rights. DuPont was not a named party in the Leach case or the Ohio MDL and it is not named as a defendant in the new cases being filed into the Ohio MDL.

In November 2023, DuPont, Chemours and Corteva reached a settlement agreement with the State of Ohio designed to benefit Ohio's natural resources and the people of the State of Ohio. Among other things, and subject to certain limitations and preservations, the settlement resolves the State's claims relating to releases of PFAS in or into the State from the companies' facilities and claims relating to the manufacture and sale of PFAS-containing products. The settlement also resolves the State's claims related to AFFF and is expected to be paid in 2024. As part of the settlement, the companies agreed to pay the State of Ohio a combined total of $110 million, 80 percent of which the State has allocated to restoration of natural resources related to operation of the Washington Works facility. Consistent with the MOU, DuPont's share of the settlement will be approximately $39 million, which is accrued for as of March 31, 2024.

In July 2021, Chemours, Corteva (for itself and EIDP) and DuPont reached a resolution with the State of Delaware for $50 million among other consideration, that avoids litigation and addresses potential natural resources damages from known historical and current releases by the companies in or affecting Delaware. In 2022, the companies paid the settlement consistent with the MOU, accordingly DuPont paid $12.5 million. The settlement provides for a potential Supplemental Payment to Delaware up to a total of $25 million, in the event certain conditions are met. As a result of the settlement agreement with the State of Ohio reached in November 2023, a Supplemental Payment is owed to the State of Delaware. The supplemental payment is to be paid subjected to the terms of the MOU. As a result, the Company has accrued approximately $9 million as of March 31, 2024 related to the Supplemental Payment.

As of March 31, 2024, there are various cases alleging damages due to PFAS which are discussed below. Such actions often include additional claims based on allegations that the transfer by EIDP of certain PFAS liabilities to Chemours resulted in a fraudulent conveyance or voidable transaction. With the exception of the fraudulent conveyance claims, which are excluded from the MOU, legal fees, expenses, costs, and any potential liabilities for eligible PFAS costs presented by the following matters will be shared as defined in the MOU between Chemours, EIDP, Corteva and DuPont.

Beginning in April 2019, several dozen lawsuits alleging damages from the use of PFAS-containing aqueous film-forming foams (“AFFF”) were filed against EIDP and Chemours, in additional to 3M and other AFFF manufacturers. The majority of these lawsuits were consolidated in a multi-district litigation (the “AFFF MDL”). The AFFF MDL is captioned In Re: Aqueous Film Forming Foams (AFFF) Products Liability Litigation and is pending in the United States District Court for the District of South Carolina, (the “Court”). Most of the actions in the AFFF MDL identify DuPont as a defendant due to fraudulent transfer claims related to the Chemours Separation and the DowDuPont separations. A portion of cases in the AFFF MDL were resolved by Chemours, Corteva, EIDP and DuPont as discussed below. DuPont has never made or sold AFFF, perfluorooctanesulfonic acid ("PFOS") or PFOS-containing products.

On June 30, 2023, Chemours, Corteva, EIDP and DuPont entered a definitive agreement to comprehensively resolve all PFAS-related claims of a defined class of U.S. public water systems, including but not limited to water systems that are part of the AFFF MDL related to the use of aqueous film-forming foam, (the “Water District Settlement Agreement”) for $1.185 billion in cash. In August 2023, the Court preliminarily approved the Water District Settlement Agreement. Subsequent to the approval, during the third quarter of 2023, Chemours, EIDP, Corteva and DuPont collectively contributed $1.185 billion to a Qualified Settlement Fund (the “Water District Settlement Fund”). In accordance with the MOU, Chemours contributed about 50 percent of the settlement amount (about $592 million), and DuPont (about $400 million) and Corteva (about $193 million) together contributed the remaining 50 percent. Each of Chemours, Corteva and DuPont used its respective MOU Escrow Account deposits to fund in part their respective contributions into the Water District Settlement Fund.

DuPont had deposited an aggregate of $100 million into the MOU Escrow Account as of June 30, 2023. The $100 million aggregate deposit was used to fund in part DuPont's $400 million contribution to the Water District Settlement Fund. DuPont's $400 million contribution was made by way of a cash payment into the fund in the third quarter 2023. At March 31, 2024, DuPont has recorded a liability of about $408 million (including interest) in connection with the Water District Settlement Agreement, included in "Accrued and other current liabilities" within the interim Condensed Consolidated Balance Sheets. As of March 31, 2024, the $400 million deposited, plus interest, within the Water District Settlement Fund is reflected in "Restricted cash and cash equivalents - current" on the interim Condensed Consolidated Balance Sheets. The Company has presented these funds as restricted cash since their use is restricted under the Water District Settlement Agreement. DuPont's aggregate MOU escrow deposits of $100 million, excluding interest, at December 31, 2023 is reflected in "Restricted cash and cash equivalents - noncurrent" on the interim Condensed Consolidated Balance Sheets.

The Water District Settlement's defined class is composed of all Public Water Systems, as defined in 42 U.S.C § 300f, with a current detection of PFAS and all Public Water Systems that are currently required to monitor for PFAS under the EPA’s Fifth Unregulated Contaminant Monitoring Rule (“UCMR 5”) or other applicable federal or state law. The class does not include water systems owned and operated by a State or the United States government; small systems that have not detected PFAS and are not currently required to monitor for it under federal or state requirements; and, unless they otherwise request to be included, water systems in the lower Cape Fear River Basin of North Carolina. While it is reasonably possible that the excluded systems or claims could result in additional future lawsuits, claims, assessments or proceedings, it is not possible to predict the outcome of any such matters, and as such, the Company is unable to develop an estimate of a possible loss or range of losses, if any, at this time.

As part of the approval process, the Court established, among other things, a mechanism for class members to submit request to be excluded from the settlement. The Notice Administrator submitted a report on February 6, 2024 indicating that 924 of 14,167 entities on the list of potential class members submitted timely requests for exclusion. The Court issued a revised order during the first quarter 2024 extending the date by which water systems that elected to be excluded from the settlement could rejoin the class to March 15, 2024. The Notice Administrator has not issued an updated report. Therefore, the number of opt-outs is not final and is subject to a court ordered review process for compliance with the opt out process.

On February 8, 2024, the Court granted the plaintiffs’ motion for final approval of the Water District Settlement Agreement and final certification of settlement class. An appeal was filed on March 11, 2024 on behalf of one water district, and was still pending at March 31, 2024. On April 16, 2024, the water district filed a motion to dismiss its appeal which the Court granted on April 17, 2024. No additional appeals were filed during the appeal period and, accordingly, the entry of judgment became final in April 2024. The Company’s contribution, including interest, paid into the Water District Settlement Fund will be removed from restricted cash along with the associated accrued liability in the second quarter 2024 due to the judgment becoming final. In the non-water provider cases in the AFFF MDL, the parties have begun the discovery process for 25 bellwether personal injury cases.

There are also state attorneys general lawsuits against DuPont, outside of the AFFF MDL that make claims of environmental contamination by certain PFAS compounds distinct from AFFF. Generally, the states raise common law tort claims and seek economic impact damages for alleged harm to natural resources, punitive damages, present and future costs to clean up contamination from certain PFAS compounds, and to abate the alleged nuisance. Most of these actions include fraudulent transfer claims related to the Chemours Separation and the DowDuPont separations.

In April 2021, a historic DuPont Dutch subsidiary and the Dutch entities of Chemours and Corteva, received a civil summons filed before the Court of Rotterdam, the Netherlands, on behalf of four municipalities neighboring the Chemours Dordrecht facility. The municipalities are seeking liability declarations relating to the Dordrecht site’s current and historical PFAS operations and emissions. On September 27, 2023, the Court determined that the defendants were liable to the municipalities for (i) PFOA emissions between July 1, 1984 to March 1, 1998 and (ii) removal costs if deposited emissions on the municipalities' land infringes the applicable municipalities' property rights by an objective standard. Additional briefing is expected on this judgment and in accordance with local procedure, the Court will determine damages, if any, in a separate, subsequent proceeding.

In addition to the above matters, the Company is a named party in various other legal matters that make claims related to PFAS, for which the costs of litigation and future liabilities, if any, are eligible PFAS costs under the MOU and Indemnification Losses under the Agreements.

There are pending cases that make claims related to PFAS that have been filed against Chemours and Corteva/EIDP in which the Company is not a named party, but for which the costs of litigation and future liabilities, if any, are or may be eligible PFAS costs under the MOU and Indemnification Losses under the Agreements.

While Management believes it has appropriately estimated the liability associated with eligible PFAS matters and Indemnifiable Losses as of the date of this report, it is reasonably possible that the Company could incur additional eligible PFAS costs and Indemnifiable Losses in excess of the amounts accrued. It is not possible to predict the outcome of any such matters due to various reasons including, among others, future actions and decisions, as well as factual and legal issues to be resolved in connection with PFAS matters. As such, at this time DuPont is unable to develop an estimate of a possible loss or range of losses, if any, above the liability accrued at March 31, 2024. It is possible that additional costs or losses could have a significant effect on the Company’s financial condition and/or cash flows in the period in which they occur; however, costs qualifying as Qualified Spend are limited by the terms of the MOU.

In addition to the matters described above, the Company is party to claims and lawsuits arising out of the normal course of business with respect to product liability, patent infringement, governmental regulation, contract and commercial litigation, and other actions. Certain of these actions may purport to be class actions and seek damages in very large amounts. As of March 31, 2024, the Company has liabilities of $20 million associated with these other litigation matters. It is the opinion of the Company’s management that the possibility is remote that the aggregate of all such other claims and lawsuits will have a material adverse impact on the interim results of operations, financial condition and cash flows of the Company. In accordance with its accounting policy for litigation matters, the Company will expense litigation defense costs as incurred, which could be significant to the Company’s financial condition and/or cash flows in the period.

Accruals for environmental matters are recorded when it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated based on current law and existing technologies. At March 31, 2024, the Company had accrued obligations of $284 million for probable environmental remediation and restoration costs. These obligations are included in "Accrued and other current liabilities" and "Other noncurrent obligations" in the interim Condensed Consolidated Balance Sheets. It is reasonably possible that environmental remediation and restoration costs in excess of amounts accrued could have a material impact on the Company’s interim results of operations, financial condition and cash flows. Inherent uncertainties exist in these estimates primarily due to unknown conditions, changing governmental regulations and legal standards regarding liability, and emerging remediation technologies for handling site remediation and restoration.
