DUPONT
CAN BE
GREAT

We have been a DuPont
owner for almost 30 years and
expect to own the stock for another 30
years. We have also invested with and alongside
Trian and have seen them create long-term
value for shareholders. As a long-term owner, we
appreciate the lasting value Trian fosters through its
constructive engagement with leadership teams...We
see the performance of the companies they engage
on a positive trajectory, from the time Trian initially
takes a position to well after they exit. Very simply,
Trian is top notch.”

ANNE SHEEHAN

Director of Corporate Governance, California State Teachers’
Retirement System, the largest teacher-only pension fund in the world

Nelson Peltz has re-organized older businesses allowing
them to expand and to thrive...Wherever we see him, we
see businesses that are adding jobs here in the United States...”

GREAT

As one of DuPont’s largest stockholders, Trian has a clear interest in the long-term success of the Company — our interests are fully aligned with those of DuPont’s employees, customers, stockholders and the Wilmington community.

Trian first invested in DuPont in March 2013. We are highly motivated to see DuPont grow and innovate once again, and we support increased dividends.

Trian offers fresh perspectives and new ideas. We have nominated four highly qualified independent directors who will seek to work collaboratively on the Board to increase value and make DuPont GREAT again.
