16. Appendix 1: Second Quarter 2014 Segment Commentary

17. 17
This data should be read in conjunction with the Company’s second quarter earnings news release dated
July 22, 2014 and DuPont’s 2Q 2014 Earnings Conference Call presentation materials and reconciliations of
non-GAAP to GAAP measures included in the presentation materials and posted on the DuPont Investor
Center website at www.dupont.com.
Nutrition & Health
Nutrition & Health, recorded a strong second quarter, building on momentum established in the third quarter
of 2013. Sales were 7 percent higher, primarily due to broad based volume growth aided by improved product
mix. We saw a strong recovery in Enablers and sustained momentum for probiotics and cultures. Volume grew
in all regions and we continue to grow in emerging markets. Operating earnings of $105 million increased 72
percent from higher sales, lower raw material costs, productivity gains and the absence of one-time costs in the
prior year. Operating margins for the quarter improved by over 400 basis points. This was the fourth
consecutive quarter of year-over-year operating margin improvement.
In the third quarter, we expect modest sales growth from continued broad based volume gains. Operating
earnings are expected to be significantly higher due to increased sales, mix enrichment and continuing
productivity actions. We will continue to make strategic investments in research, application development and
customer facing resources to drive future growth. Operating margins are expected to continue the trend of
year over year improvement.
Segment Commentary – Second Quarter Earnings 2014

18. 18
Industrial Biosciences
Industrial Biosciences sales of $317 million were 4 percent higher on higher prices due to mix enrichment,
improved margins and higher volumes. Continued strong enzyme demand for ethanol production was partially
offset by lower sales of Sorona® polymer due to lower existing home sales. Strong sales of Axtra® PHY in
animal nutrition markets paired with healthy food enzyme demand also increased volumes and margins.
Operating earnings of $59 million were up 37 percent, primarily driven by mix enrichment, improved margins
associated with new products, and volumes in biorefineries and bioactives. For the first half, segment
operating earnings were up 37% and operating margins are up 440 basis points from the prior year.
Favorable industry fundamentals for ethanol are driving increased enzyme demand as ethanol margins are
attractive and production is near capacity. Enzyme volumes in the grain ethanol market are also being driven
by the roll out of DuPont’s Total Performance System (TPS) using novel enzymes and other functional bio-
products designed to increase customer earnings through increased production rates, yield, and efficiency.
Since introduction in late 2013, TPS has been adopted across a diverse set of ethanol production plants.
Further adoptions are planned. We are implementing TPS as our standard offering for the industry, with next-
generation versions already in preparation for launch.
For the third quarter, we expect modest sales growth aided by continued enzyme demand for ethanol
production and stronger forecasted sales of Sorona®. Third quarter operating earnings are expected to be up
substantially driven primarily by higher volumes and improved margins.
Segment Commentary – Second Quarter Earnings 2014

19. 19
Safety & Protection
Sales of $1,029 million were up 1 percent on higher volumes in industrial markets. Improved Nomex® thermal
resistant and Kevlar® high strength materials demand was partially offset by lower sales from Clean Technologies
offerings, as fewer sulfuric acid recovery plants were built.
Kevlar® demand growth was driven by increased sales into law enforcement, transportation and wire & cable
sectors while Nomex demand improved in energy solution and thermal industrial applications. Regionally, sales
volume growth was most notable in Europe and in Asia Pacific, partially offset by lower prices.
Second quarter segment operating earnings of $209 million increased 22 percent and operating margins
increased over 300 basis points. Segment operating earnings are benefiting from improved margins, increased
demand from industrial markets and continued benefits from cost productivity initiatives coupled with improved
plant operating results.
For the third quarter, sales are anticipated to be up modestly reflecting improved industrial demand, and
operating earnings will be up about 20 percent, driven by higher operating margins and sustained operational
productivity.
Segment Commentary – Second Quarter Earnings 2014

20. 20
Electronics & Communications
Electronics & Communications sales were essentially flat excluding the impact of lower metals price pass
through. Volume growth in most product lines, led by gains in consumer electronics, was offset by lower price
due to metals, product mix and competitive pressures. Operating earnings declined $6 million as volume
growth and productivity gains were more than offset by the absence of $20 million of OLED licensing income
realized during the second quarter of 2013. Excluding the impact of last year’s licensing income, operating
earnings increased 19 percent.
Looking ahead to the third quarter, we continue to expect global photovoltaic module installations to be up for
the year with mid-teens growth rates. We expect a strong 2H in photovoltaics driven by installations in China
and good demand for our products in consumer electronics markets. Third quarter sales are expected to be
slightly higher with operating earnings slightly lower due to a decrease in other income.
Segment Commentary – Second Quarter Earnings 2014

21. 21
Performance Materials
Sales of approximately $1.6 billion were down 2 percent principally due to the scheduled outage at the Orange,
Texas ethylene unit and portfolio changes. Volumes in Performance Polymers were up mid-single digits fueled by
strong automotive demand in China, Europe and North America. The demand environment in consumer,
construction and food packaging markets remains stable. Demand for high performance parts, principally
Kalrez® and Vespel® for electronics, oil and gas, and aerospace applications was up about 10 percent.
Segment operating earnings were $303 million or 9 percent below last year as lower sales volume resulting from
the scheduled ethylene outage was partially offset by sales gains in Performance Polymers.
In the third quarter, we anticipate sales will be essentially flat versus the prior year as the impact of portfolio
changes; principally the Glass Laminating/Vinyls sale in the second quarter offsets anticipated volume growth in
Performance Polymers. We expect operating earnings will be up modestly from the prior year, which included a
$30 million dollar benefit from a joint venture equity position.
Segment Commentary – Second Quarter Earnings 2014

22. 22
Segment Commentary – Second Quarter Earnings 2014
Performance Chemicals
Segment sales of approximately $1.7 billion were down 8 percent due to a portfolio change and lower prices.
Slightly higher Ti02 volumes were more than offset by lower volumes in Chemicals and Fluoroproducts.
Second quarter refrigerant prices for mobile and stationary applications were lower than expected as prices for
R22 have not recovered from the prior year following the increase in production allocations granted by the U.
S. Environmental Protection Agency. In addition, HFC prices, principally 134a, were under pressure due to
heavy imports. Demand for Opteon® yf for mobile air conditioning continues to grow. In 2014, we anticipate
sales will double to reach approximately $100 million as automotive OEMs increase their rate of adoption of
this new product.
In Ti02, volumes were up slightly from the prior year, marking six consecutive quarters of year over year volume
growth. Ti02 prices were essentially flat sequentially but down about 3% on a year over year basis. We believe
our customer’s inventory levels are stable and producer levels remain essentially unchanged.
In the third quarter, we anticipate sales will be essentially flat and operating earnings up moderately on higher
volumes and improved operating margins.

23. 23
Segment Commentary – Second Quarter Earnings 2014
Agriculture
In Agriculture, second quarter results finished in-line with the update we provided in late June. Supply-driven
impacts on commodity prices led to reductions in corn planted area in the North America and Brazil Safrinha
seasons. Second quarter sales were essentially flat as higher seed prices and higher insecticide and soybean
seed volumes were offset by lower corn seed and herbicide volumes. Operating earnings for the quarter were
11 percent lower as higher seed prices and lower seed input costs were more than offset by lower overall
volumes and higher seed inventory write-downs.
For the first half, which encompasses the majority of the northern hemisphere season and the completion of
Brazil’s Safrinha season, segment sales were 4 percent lower.
Crop protection sales grew 4 percent in the first half driven by strong demand for insecticides in Latin America
due to heavy insect pressure and the excellent performance of Rynaxypyr® insecticide. This was partially offset
by lower herbicide volumes in North America and Europe. Herbicide volumes were negatively impacted by a
wet spring, a delayed and compressed application season, and distributor de-stocking of elevated inventory
levels.
In seeds, first half sales were 6 percent lower. The first half comparison was negatively impacted by the earlier
timing of seed shipments which caused about $100 million of operating earnings to be realized in the fourth
quarter of 2013 rather than the first quarter this year. Higher prices and higher soybean volumes in North
(continued)

24. 24
Segment Commentary – Second Quarter Earnings 2014
(continued)
America were more than offset by the decline in corn seed volumes. Price gains were achieved in North
America due to improved product mix as Optimum® AQUAmax® hybrids were planted on over 10 million acres
and Optimum® AcreMax® products represented about two-thirds of our corn sales volume in North America.
First half operating earnings for the segment were 7 percent lower as lower seed input costs were more than
offset by lower sales and higher seed inventory write-downs.
As we turn to the second half, we expect sales to be modestly higher with operating earnings substantially
higher for the Agriculture segment. Rynaxypyr® is expected to continue to drive growth in insect control
aided by new launches of Cyazypyr® and Lumigen™ seed treatments, including Dermacor™ for use on
soybeans in Brazil. In seeds, we expect lower corn sales in Brazil’s summer season as growers continue to shift
hectares from corn to soybeans. Corn seed price in Brazil is expected to be modestly lower reflecting the
impact of fall armyworm resistance to the Herculex® 1 trait. Herculex® 1 combined with leading Pioneer
germplasm continues to offer control of a broad spectrum of pests. We also expect early seed shipments for
the 2015 Brazil Safrinha and northern hemisphere seasons to be similar to the prior year.
While the cutoff between third quarter and fourth quarter sales comes at an important time in the Latin
America season, we expect the third quarter to result in a similar loss as last year followed by a stronger
fourth quarter. In addition, the third quarter comparison will be impacted by the absence of a $26 million
equity re-measurement gain from the acquisition of Pannar which was recorded in the prior year.
