Exelon Named to Dow Jones Sustainability Index for 12th Consecutive Year

Company recognized for continued excellence in environmental
stewardship and innovation and being a workplace of choice

CHICAGO–(BUSINESS WIRE)–Exelon Corporation ranks among the industry leaders in corporate
sustainability based on several key measures, including environmental
policies, innovation and attracting and retaining talented employees,
according to the 2017 Dow Jones Sustainability Index (DJSI). The company
was recognized by the global report, which reviews the 600 largest North
American companies, for the 12th consecutive year. Exelon was one of
eight electric and gas companies to be named to the DJSI for North
America out of 32 companies in the utilities category.

“Being an industry leader means making a significant effort to deliver a
cleaner, brighter energy future,” said Chris Crane, Exelon’s President
and CEO. “The customer is at the center of all we do, and we are proud
to be recognized for our consistent efforts to innovate and develop
solutions so we can deliver on our sustainability commitments to our
customers and communities.”

The DJSI assessment is conducted each year by sustainability investment
specialist RobecoSAM. It is based on a comprehensive review of
environmental performance, innovation management, corporate governance,
risk management, stakeholder engagement and talent attraction and
retention.

In 2016, Exelon demonstrated outstanding performance in these areas,
including helping customers save enough electricity to power more than
1.5 million homes for one year.

The company’s annual Innovation Expo continues to bring employees and
industry experts together to explore new approaches to challenges
affecting the energy industry as well as ways to improve customer
experience and service. Outstanding employee ideas, including the 2016
winner who developed an updated process for utility inventory control,
are adopted by the business. This year’s leading entries out of 500
employee presentations included a proposal to incorporate fuel
generation into Exelon’s commercial product portfolio and a digital tool
for more detailed views of the company’s nuclear plants.

In 2016, Exelon’s continued focus on programs and policies to benefit
employees included signing the national Equal Pay Pledge commitment to
gender pay equity and expanding family leave benefits with an
industry-leading benefit package. For these and other efforts, Exelon
was named one of DiversityInc.’s “Diversity50” as well as a “Best Place
to Work” by Indeed.com in 2017.
