filing a patent for such technologies.

Litigation related to Corteva’s current businesses

Inari Disputes

On September 27, 2023, Corteva filed a lawsuit in Delaware federal court against Inari Agriculture, Inc.

and Inari Agriculture.

(collectively “Inari”) asserting claims of Plant Variety Protection infringement, indirect patent infringement, breach of contract, and civil conversion.

Corteva’s lawsuit alleges Inari illegally obtained various varieties of seed technologies from a seed depository and illegally transported them abroad for the purpose of performing gene editing on the technologies and then filing a patent for such technologies.

In August 2024, the court denied Inari's motion to dismiss the complaint.

In September 2024, Corteva amended its complaint to include additional infringement claims with respect to soybean and corn technologies.

In May 2025, the federal court dismissed Inari’s claims of sham litigation, patent misuse, and state-based deceptive trade practices claims.

This May 2025 order was amended to reinstate Inari’s estoppel defense.

The trial is expected to begin in the second half of 2026.

Bayer Disputes

In August 2022, Corteva filed a lawsuit against Bayer CropScience LLP and Monsanto Company (collectively “Bayer”) in federal court in Delaware for alleged infringement of Corteva’s patented AAD-1 herbicide resistance technology used in Enlist® corn.

The complaint for this lawsuit was amended to include additional patents that are closely related to this patented technology for soybeans.

Corteva seeks to enjoin Bayer from continuing to infringe, as well as appropriate monetary damages.

Bayer has filed an answer to the complaint and has asserted various affirmative defenses including invalidity.

In August 2023, the court issued a decision adopting Corteva’s claim construction for all five disputed patent terms subject to this litigation.

In December 2023, the Patent Trial and Appeal Board ("PTAB") authorized an Inter Partes Review (“IPR”) proceeding initiated by Bayer to review the patentability of three patents subject to the AAD-1 litigation.

Inari joined the IPR proceeding.

In December 2024, the PTAB issued a decision invalidating these patents on the basis they were unpatentable.

Corteva intends to appeal this decision and Corteva's AAD-1 lawsuit remains stayed during pendency of the IPR appeal.

Corteva holds numerous additional patents covering its Enlist® traits or Enlist® weed control system.

Therefore, the IPR process is not expected to impact our ability to license and protect Enlist E3® traits.

In October 2023, the U.S.

Patent and Trademark Office granted an ex parte reexamination of the patent for AAD-1 herbicide resistance technology used in Enlist® corn based upon Inari’s petition for review.

Inari alleges the AAD-1 patent is not patentably distinct from another Corteva patent for maize technology, and therefore not valid unless Corteva files a terminal disclaimer giving up its patent term adjustment for the AAD-1 technology, which would result in the AAD-1 patent expiring in May 2025.

In August 2022, Bayer filed breach of contract/declaratory judgment lawsuit in Delaware state court against Corteva relating to an agrobacterium cross-license agreement and E3® soybeans.

Further information with respect to these proceedings is set forth under “Bayer Dispute” in Note 16 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements.

In October 2022, Corteva filed a lawsuit against Bayer in Delaware state court seeking a declaration that, under the terms of Corteva’s licensing agreement and the law, Bayer is not entitled to collect patent royalties on the Roundup Ready® Corn 2 trait after Bayer’s U.S.

patent protection expires, and therefore is no longer required to pay royalties under the licensing agreement and entitled to recover relevant royalties paid.

In September 2024, the court granted Bayer’s motion for summary judgment.

Corteva filed its appeal of this decision in October 2024.

Discussions continue between Bayer and Corteva to seek a resolution to these disputes.

Corteva resolved its outstanding litigation with Bayer.

Further information with respect to these proceedings and their respective resolution is set forth under "Bayer Disputes" in Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements.

Other Matters

2 unchanged sentences

As discussed below and in Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, certain of the environmental proceedings and litigation allocated to Corteva as part of the Separation from DuPont relate to the legacy EIDP businesses, including their use of PFOA, which, for purposes of this report, means collectively perfluorooctanoic acid and its salts, including the ammonium salt and does not distinguish between the two forms, and PFAS, which means per- and polyfluoroalkyl substances, including PFOA, PFOS (perfluorooctanesulfonic acid), GenX and other perfluorinated chemicals and compounds ("PFCs").

This litigation includes multiple natural resource damage lawsuits across the United States filed by municipalities and alleging PFOA contamination, as well as, lawsuits by four municipalities in the Netherlands alleging contamination of land and groundwater resulting from the emission of PFOA and GenX by Corteva, DuPont and Chemours.

In addition to the matters set forth in Note 16 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements, on March 25, 2019, the New Jersey Department of Environmental Protection (“NJDEP”) issued a Statewide PFAS Directive to several companies, including Chemours, DuPont, and EIDP.

The Directive seeks information relating to the use and environmental release of PFAS and PFAS-replacement chemicals at and from two former EIDP sites in New Jersey, Chambers Works and Parlin, and a funding source for costs related to the NJDEP’s investigation of PFAS issues and PFAS testing and remediation.

Other Environmental Proceedings

6 unchanged sentences

Further information with respect to these proceedings is set forth under “Nebraska Department of Environment and Energy, AltEn Facility” in Note 15 - Commitments and Contingent Liabilities, to the Consolidated Financial Statements.

Bay Area Quality Management, Pittsburg Facility

In December 2025, the Bay Area Quality Management District sent a notice to the company proposing a settlement for allegations of notices of violations from 2010 to 2023 relating to emissions, equipment leaks, monitoring inspections, recordkeeping, and training, at the company’s Pittsburg, California facility.

Related to legacy EIDP businesses unrelated to Corteva’s current businesses

3 unchanged sentences

In the spring of 2017, the EPA, the DOJ, the Louisiana Department of Environmental Quality, EIDP and Denka began discussions relating to the inspection conclusions and allegations of noncompliance arising under the Clean Air Act, including leak detection and repair.

These discussions, which include potential settlement options, continue.

In March 2025, the EPA and DOJ dismissed the action against Denka and EIDP.

Following the dismissal, a private action mirroring the government’s original claims was filed, as well as adding allegations of violations of the U.S.

Resource Conservation and Recovery Act and U.S.

Clean Water Act.

Under the Separation Agreement, DuPont is defending and indemnifying the company in this matter.

New Jersey Directive Pompton Lakes

On March 27, 2019, the NJDEP issued to Chemours and EIDP a Natural Resource Damages Directive relating to chemical contamination (non-PFAS) at and around EIDP’s former Pompton Lakes facility in New Jersey.

The Directive alleges that this contamination has harmed the natural resources of New Jersey.

It seeks $125,000 as reimbursement for the cost of preparing a natural resource damages assessment, which the State will use to determine the extent of such damage and the amount it expects to seek to restore the affected natural resources to their pre-damage state.

EPA CERCLA Claim

In April 2024, the U.S.

Environmental Protection Agency ("EPA") also designated PFOA and PFAS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA").

In April 2024, the EPA also designated PFOA and PFAS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA").

In November 2024, the EPA issued a letter to DuPont, EIDP and Corteva asserting CERCLA claims related to alleged PFAS contamination from six historical and present DuPont and Chemours sites and providing a demand for cleanup and restoration costs.

In February 2025, discussions between the parties regarding these claims were temporarily paused so the new U.S.

presidential administration may review the designation of PFOA and PFOS as CERCLA hazardous substances.

In September 2025, the EPA announced its intent to retain the designation of PFOA and PFOS as CERCLA hazardous substances.

Discussions among the parties are ongoing.
