Corteva Announces Plan to Separate

into Two Industry-Leading Public Companies

Separation to give shareholders two compelling investment opportunities

Indianapolis, Ind., October 1 – Global agriculture technology leader Corteva (NYSE: CTVA) announced today that its Board of Directors has unanimously approved a plan to separate the company into two independent, publicly traded companies, one comprising its current Crop Protection business (“New Corteva”) and the other comprising its current Seed business (“SpinCo”).

The separation will unleash two distinct market leaders, both farmer-centric, both with technology and innovation at their core and both with operating models and capital allocation priorities tailored to support their respective growth outlooks, strategic directions and value propositions. Upon separation, current Corteva Chair Greg Page will become Chair of New Corteva; current Corteva CEO Chuck Magro will become CEO of SpinCo. Full board and management teams of both companies will be announced at a later date, followed by other key information.

“Over the past six years, we have taken deliberate steps to build a strong, successful technology company: we simplified our portfolio, reduced cost, invested in high-return endeavors and ensured our pipeline would maximize impact to farmers and returns to the company. As a result, Corteva has become the clear industry leader, with market-leading positions in both crop protection and seed. As we look to the future, we want to best position both businesses to win in their respective markets and accelerate value for shareholders,” said Corteva CEO Chuck Magro.

Magro continued, “The seed and crop protection markets have evolved, and as a result, we see the opportunities ahead for both companies diverging – this is the right time to act to stay ahead of the market. This separation will allow both businesses to maximize long-term value creation by focusing on their own priorities. As such, we see this separation as the logical next step in their growth trajectory.”

Each business is expected to benefit from the separation through the following:

New Corteva: a Global Leader with a Track Record of Operational Excellence and a Comprehensive Portfolio Focused on Differentiated, Innovative Solutions

Over the past few years, with its focus on efficiency and differentiation, the business that will become New Corteva has been a strong performer in an industry experiencing intensifying competition. Today, while the industry is well supplied – not only in production and capacity, but also with market participants – the market continues to value effective, differentiated technology, and this focus will help the company continue to stand apart from its peers.

New Corteva will nonetheless operate in an industry that will need to compete differently in the future. As such, it will continue its progress towards an optimized supply chain and have a laser focus on maximizing shareholder returns, operational excellence and the next generation of sustainable, differentiated innovation – including biologicals, the industry’s fastest growing market segment.

As a scaled, standalone company, New Corteva’s capital structure and targeted investment-grade credit rating will be tailored for a business model designed to support future capital needs and deliver consistent growth over time. Capital will be directed towards organic investment in differentiated solutions, innovation to bring advanced sustainable solutions to farmers, and disciplined M&A to expand market positions in attractive portfolios or geographies.

New Corteva’s partners will benefit from its focused, more optimized route to market. In addition, the company will be able to drive more effective channel management. New Corteva will also benefit from enhanced strategic flexibility, collaboration and partnership across the industry to drive efficiency and value.

Through a focus on returns, targeted investment and operational excellence, New Corteva will help farmers solve some of their toughest challenges and continue to lead the industry in crop protection. 2025 net sales attributable to New Corteva are estimated to total $7.8 billion, representing 44% of net sales for Corteva.

SpinCo: an Unrivaled Innovator with a Century-Long Track Record Poised to Accelerate Growth

SpinCo will deploy advanced genetics to discover and develop groundbreaking solutions that help farmers around the world improve yield, enhance sustainability and strengthen crop health. As home to the Pioneer^® brand, it will launch from a position of strength: Pioneer’s century-long track record of advanced breeding, market leadership and financial strength is unmatched in the industry. SpinCo, a classic growth compounder, will also leverage other opportunities, including the strength of its regional anchor brands, including Dairyland Seed^®; its partnership with retailers through brands like Brevant^®; and growing presence in the out-licensing market.

As a scaled standalone company, SpinCo will target an investment-grade rating, with capital allocation priorities tailored to its growth model. This will include targeted M&A, sustained investment in R&D and the fulfillment of existing opportunities: out-licensing, hybrid wheat, biofuels and gene editing.

By consistently delivering value to farmers and shareholders alike, SpinCo will deliver its next phase of innovation-driven growth. 2025 net sales attributable to SpinCo are estimated to total $9.9 billion, representing 56% of net sales for Corteva.

Transaction Details

The separation is expected to be effected through a spin-off of SpinCo that is intended to qualify as a tax-free transaction for U.S. federal tax purposes to Corteva shareholders.

The transaction is expected to be completed in the second half of 2026, subject to certain conditions, including, among others, obtaining final approval by the Corteva Board of Directors, receipt of a favorable opinion of legal counsel with respect to the tax-free nature of the transaction for U.S. federal income tax purposes, and effectiveness of a Form 10 registration statement to be filed with the U.S. Securities and Exchange Commission. Corteva may, at any time and for any reason until the proposed transaction is complete, abandon the separation or modify or change its terms.
