NOTE 1 - BACKGROUND AND BASIS OF PRESENTATION

Corteva, Inc. is a leading global provider of seed and crop protection solutions focused on the agriculture industry. The company intends to leverage its rich heritage of scientific achievement to advance its robust innovation pipeline and continue to shape the future of responsible agriculture. The company's broad portfolio of agriculture solutions fuels farmer productivity around the globe. Corteva has two operating segments: Seed and Crop Protection. See Note 22 - Segment Information, to the Consolidated Financial Statements, for additional information on the company's operating segments.

Throughout these financial statements, except as otherwise noted by the context, the terms "Corteva" or "company" used herein mean Corteva, Inc. and its consolidated subsidiaries (including EIDP) and the term “EIDP” used herein means EIDP, Inc. (formerly known as E. I. du Pont de Nemours and Company) and its consolidated subsidiaries or EIDP, Inc. excluding its consolidated subsidiaries, as the context may indicate.

Principles of Consolidation and Basis of Presentation

The consolidated financial statements contained in this Annual Report were prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") for all periods presented and include the accounts of the company, its majority owned subsidiaries over which the company exercises control. The Consolidated Financial Statements and other financial information included in this Annual Report, unless otherwise specified, have been presented to separately show the effects of discontinued operations.

On June 1, 2019, Corteva, Inc. became an independent, publicly traded company through the completed separation of the agriculture business (the “Corteva Separation”) of DuPont de Nemours, Inc. (formerly known as DowDuPont Inc.) (“DowDuPont” or “DuPont”). The Corteva Separation was effectuated through a pro rata distribution (the “Corteva Distribution”) of all of the then-issued and outstanding shares of common stock of Corteva, Inc.

Prior to the Corteva Separation, subsequent to the Merger, Historical Dow and EIDP engaged in a series of internal reorganization and realignment steps to realign their businesses into three subgroups: agriculture, materials science and specialty products ("Internal Reorganization"). On April 1, 2019, DowDuPont completed the separation of its materials science business into a separate and independent public company by way of a distribution of Dow common stock to holders of DowDuPont's common stock (the “Dow Distribution” and together with the Corteva Distribution, the “Distributions”).

On April 1, 2019, Historical Dow entities, which held certain assets and liabilities aligned with Historical Dow’s agriculture business and the assets and liabilities associated with its specialty products business, respectively, were transferred and conveyed to DowDuPont.

On April 1, 2019 and May 1, 2019, EIDP’s materials science and specialty products entities, along with their respective assets and liabilities, were conveyed to Dow and DowDuPont, respectively. On May 2, 2019, DowDuPont conveyed Historical Dow agricultural entities to EIDP.

On May 6, 2019, the Board of Directors of DowDuPont approved the distribution of all the then issued and outstanding shares of common stock of Corteva, Inc., then a wholly-owned subsidiary of DowDuPont, to DowDuPont stockholders. On May 31, 2019, DowDuPont contributed EIDP to Corteva, Inc. and on June 1, 2019, the Corteva Separation was completed. Information related to the Corteva Distribution and its effect on the company's financial statements is discussed throughout these Notes to the Consolidated Financial Statements.

Since 2018, Argentina has been considered a highly-inflationary economy under U.S. GAAP and, therefore, the U.S. Dollar (“USD”) is the functional currency for our related subsidiaries. Argentina contributes approximately 3 percent to the company's annual net sales and approximately 1 percent to each of the company's annual Seed and Crop Protection segment operating EBITDA. The company remeasures net monetary assets and translates the financial statements utilizing the official Argentine Peso (“Peso”) to USD exchange rate. The ability to draw down Peso cash balances is limited at this time due to government restrictions and market availability of U.S. Dollars. The devaluation of the Peso relative to the USD over the last several years has resulted in the recognition of exchange losses (refer to Note 6 – Supplementary Information, to the Consolidated Financial Statements). The Argentina government has offered USD-denominated bonds to importers, the proceeds from which could be used to pay off outstanding intercompany payables. As of December 31, 2025, the company holds these foreign government bonds with an amortized cost of $30 million as part of its strategy to manage its net monetary asset exposure in Argentina. Refer to the “Debt Securities” section in Note 19 - Financial Instruments, to the Consolidated Financial Statements, for additional information. As of December 31, 2025, a further 10 percent deterioration in the official Peso to USD exchange rate

would not have a significant impact on the USD value of our net monetary assets or pre-tax earnings. The company will continue to assess the implications to its operations and financial reporting.

BASIS OF PRESENTATION

Corteva, Inc. owns 100 percent of the outstanding common stock of EIDP. EIDP is a subsidiary of Corteva, Inc. and continues to be a reporting company, subject to the requirements of the Exchange Act. The primary differences between Corteva, Inc. and EIDP are outlined below:

•Preferred Stock - EIDP has preferred stock outstanding to third parties which is accounted for as a noncontrolling interest at the Corteva, Inc. level. Each share of EIDP Preferred Stock - $4.50 Series and EIDP Preferred Stock - $3.50 Series issued and outstanding at the effective date of the Corteva Separation remains issued and outstanding as to EIDP and was unaffected by the Corteva Separation.

•Related Party Loan - EIDP engaged in a series of debt redemptions during the second quarter of 2019 that were partially funded through an intercompany loan from Corteva, Inc. This was eliminated in consolidation at the Corteva, Inc. level but remained on EIDP's consolidated financial statements at the standalone level (including the associated interest) through its repayment date in the fourth quarter of 2023.

•Master In-House Banking Agreement - A Master In-House Banking Agreement exists to which EIDP is a party, along with Corteva and certain consolidated subsidiaries, as more fully described in EIDP Note 2 – Related Party Transactions, of the EIDP Consolidated Financial Statements. Through the third quarter of 2024, EIDP earned interest on Corteva, Inc.’s borrowings under the Master In-House Banking Agreement; however, beginning in the fourth quarter of 2024 no interest has been recognized by EIDP and the amount due from Corteva, Inc. is classified within equity of EIDP due to a change in repayment intent related to the arrangement. Such transactions are eliminated in consolidation at the Corteva, Inc. level.

•Dividends - The Board of Directors of EIDP authorizes and declares a quarterly dividend to Corteva, Inc., from which the proceeds are intended to be used to fund Corteva, Inc. share repurchases and common stock dividends during the subsequent quarter.

•Capital Structure - At December 31, 2025, Corteva, Inc.'s capital structure consists of 672,163,000 issued shares of common stock, par value $0.01 per share.
