Douglas Muzyka presented on DuPont's strategy to drive higher growth and value through science. The company focuses on three strategic priorities: extending leadership in agriculture and nutrition, building bio-based industrial businesses, and strengthening its position in advanced materials. DuPont will pursue these priorities through innovation in key markets like food, energy, and protection, applying its integrated science capabilities. The company aims to achieve 7% sales growth and 12% operating EPS growth through these initiatives and operational priorities of innovation, global reach, and execution.

Regulation G
The attached charts include company information that does not conform to generally accepted accounting principles
(GAAP). Management believes that an analysis of this data is meaningful to investors because it provides insight with
respect to ongoing operating results of the company and allows investors to better evaluate the financial results of the
company. These measures should not be viewed as an alternative to GAAP measures of performance. Furthermore,
these measures may not be consistent with similar measures provided by other companies. This data should be read in
conjunction with previously published company reports on Forms 10-K, 10-Q, and 8-K. These reports, along with
reconciliations of non-GAAP measures to GAAP are available on the Investor Center of www.dupont.com under Key
Financials & Filings.
Forward Looking Statements
During the course of this presentation we may make forward-looking statements or provide forward-looking
information. All statements that address expectations or projections about the future are forward-looking statements.
Some of these statements include words such as “plans,” “expects,” “will,” “anticipates,” "believes," “intends,” and
“estimates.” Although they reflect our current expectations, these statements are not guarantees of future
performance, but involve a number of risks, uncertainties, and assumptions. Some of which include: fluctuations in
energy and raw material prices; failure to develop and market new products and optimally manage product life cycles;
global economic and capital markets conditions; litigation and environmental matters; changes in laws and regulations
or political conditions; business or supply disruptions; ability to protect and enforce the company’s intellectual property
rights; successful integration of acquired business and separation of underperforming or non-strategic assets; and
successful completion of the proposed spinoff of the Performance Chemicals segment including ability to fully realize
the expected benefits of the proposed spinoff. The company does not undertake to update any forward-looking
statements as a result of future developments or new information.
Developing Markets
Total developing markets is comprised of Developing Asia, Developing Europe, Middle East & Africa, and Latin America.
A detailed list of all developing countries is available on the Earnings News Release link on the Investor Center website

Note : Operating earnings are defined as earnings from continuing operations (GAAP) excluding “significant items” and “non-operating pension and other post-employment benefit (OPEB) costs”.
Management believes that an analysis of operating earnings, a "non-GAAP" measure, is meaningful to investors because it provides insight with respect to ongoing operating results of the company.
Such measurements are not recognized in accordance with generally accepted accounting principles (GAAP) and should not be viewed as an alternative to GAAP measures of performance.
