DuPont Files New Investor Presentation

Board of Directors Urges Shareholders to Vote “FOR” ALL 12 of DuPont’s

Experienced and Highly Qualified Director Nominees

WILMINGTON, Del., Apr. 6, 2015 — DuPont (NYSE: DD) today announced that it has filed a new investor presentation with the U.S. Securities and Exchange Commission (SEC) in connection with the Company’s May 13, 2015 Annual Meeting of Shareholders. The presentation is available under the shareholder materials section of www.dupontdelivers.com and on the SEC’s website at www.sec.gov.

The presentation highlights the growth of DuPont’s ongoing, post-spin business, demonstrating the strength of the next generation DuPont. The ongoing business has delivered 6% segment sales growth(1) and a 19% adjusted operating EPS compound annual growth rate since December 31, 2008.(2) In addition, the Company’s segment adjusted operating margin has improved 740 basis points.(3)

The presentation also outlines DuPont’s strong and consistent track record of superior performance; its strategy to grow leading positions in three areas of strategic focus; and the qualifications of its world-class Board of Directors to drive higher growth and higher value for our shareholders.

In addition, the presentation illustrates in greater depth why DuPont’s Board unanimously opposes Trian’s efforts to replace four highly accomplished directors in order to advance its high-risk, high-cost breakup agenda, which the Board has unanimously determined would be value destructive and not in the best interests of shareholders.

Highlights of the presentation include:

Results Delivered by Management and the Board

·DuPont has delivered superior total shareholder returns—266% compared to 159% from the S&P 500 and 133% from our proxy peers.(4)

·DuPont has transformed its portfolio—Acquired higher growth, higher value businesses like Danisco and Pannar Seed, and divested more commoditized and cyclical businesses such as Performance Coatings and the upcoming spinoff of Chemours.

·DuPont has significantly streamlined operations, improved productivity and reduced costs and is taking this process even further.  Through the redesign initiative launched in 2014, the Company expects annual run-rate savings of $1 billion by the end of 2015, and $1.3 billion by the end of 2017.

·Continued to return significant capital to shareholders—$14 billion in cumulative dividends and buybacks since December 31, 2008. DuPont expects to return to shareholders substantially all of the one-time dividend proceeds from Chemours — currently estimated at approximately $4 billion.(5)

·The actions taken to date have resulted in a next generation DuPont with a much stronger growth profile. The Company’s ongoing business has delivered 6% segment sales growth,(6) and a 19% adjusted operating EPS compound annual growth rate since December 31, 2008.(7)

Details on DuPont’s Higher Growth, Higher Value Strategy

In the presentation, DuPont outlines in detail how it will continue its track record of superior results by building and leveraging its world leading positions in three highly attractive strategic focus areas:

·Extending its leadership position in Agriculture & Nutrition.

·Strengthening and growing its leading position in Advanced Materials.

·Continuing to build transformational new businesses in Bio-based Industrials.

These areas are all characterized by robust opportunities where DuPont has a strong competitive position. The Company will deliver higher growth, higher value in these three strategic areas through a continued focus on:

·Leveraging its innovation platform to deliver above market growth;

·Increasing penetration in developing markets and delivering local solutions;

·Driving operational efficiency and effectiveness; and

·Actively managing the portfolio.

DuPont’s Strong, Independent Board with the Right Mix of Experience and Skills

The DuPont Board of Directors has been carefully structured to incorporate the full range of experiences and skills required to lead a global science and technology company of DuPont’s scale—particularly one in the midst of transformational change. The directors have been specifically identified and recruited to ensure that the Board is composed of exceptional individuals who, together, have the right mix of capabilities to deliver superior shareholder value. Important facts about the Board include:

·All of the Directors are independent, except CEO Ellen Kullman;

·Ten of DuPont’s independent Board members are current or former CEOs, CFOs or COOs of major public companies;

·The Board includes directors with essential scientific and regulatory knowledge;

·The Company has added the fresh perspectives of six new directors since 2011, including two in February 2015 — Edward Breen and James Gallogly — who have significant experience in business transformations and proven track records of creating shareholder value; and

·Trian is attempting to replace four DuPont directors who are exceptionally well-qualified. These directors chair several key committees and have made significant, unique contributions as Board members that have enhanced the value of the Company.

Adding a Trian Representative to the DuPont Board Is NOT in the Best Interests of Shareholders

Trian is pushing a value-destructive agenda to break up and add excessive debt to DuPont, which the Board believes will result in a less competitive company with weaker prospects for value creation:

·Carries extensive risks as well as estimated upfront monetary impact of $4 billion and estimated ongoing increased costs of $1 billion annually; (8)

·Destroys innovation platform, which serves as unique competitive advantage;

·Eliminates revenue and margin drivers across businesses, including: global reach, customer relationships, brand awareness, market position, cross selling opportunities and market access; and

·Addition of excessive debt would increase risk and adversely impact DuPont’s credit rating.

The DuPont Board unanimously determined that adding Nelson Peltz or any Trian principal is not in the best interest of shareholders.

·Trian is singularly focused on a value destructive agenda;

·Trian has a well-known practice of establishing a ‘shadow management’ team, which would be committed to advancing Trian’s value destructive breakup agenda and risks derailing ongoing execution and focus on advancing the strategy of the Company;

·None of Trian’s nominees add value or skills needed to advance DuPont’s strategy;

·Trian’s only recent experience in DuPont’s industry was Chemtura, which ended in bankruptcy and complete destruction of all shareholder value.

DuPont shareholders are reminded that their vote is extremely important, no matter how many or how few shares they own. DuPont strongly recommends that shareholders elect the Company’s world-class leaders by voting the WHITE proxy card today “FOR” ALL 12 of DuPont’s highly-qualified and experienced director nominees: Lamberto Andreotti, Edward D. Breen, Robert A. Brown, Alexander M. Cutler, Eleuthère I. du Pont, James L. Gallogly, Marillyn A. Hewson, Lois D. Juliber, Ellen J. Kullman, Ulf M. Schneider, Lee M. Thomas and Patrick J. Ward. In addition, we ask that you not return the “gold” card, even to withhold on their nominees, as it will revoke any previous WHITE card that you may have submitted in support of your DuPont Board nominees.

Each and Every Vote is Important!

REMEMBER:

We urge shareholders to simply discard any “gold” proxy card they may receive from Trian. Submitting a vote on the gold proxy card — even if shareholders “withhold” on Trian’s nominees — will revoke any vote previously submitted on DuPont’s WHITE proxy card.  The best way to support the DuPont Board is to vote using ONLY the WHITE proxy card.
