Owens Corning Named One of the 2019 World’s Most Ethical Companies® by the Ethisphere Institute for the Second Year

For the second consecutive year, Owens Corning (NYSE: OC) has been
recognized by the Ethisphere Institute as one of the 2019 World’s Most
Ethical Companies.

The Ethisphere Institute, a global leader in defining and advancing the
standards of ethical business practices, recognized Owens Corning again
this year as one of four honorees in the Construction & Building
Materials industry, underscoring its commitment to leading with
integrity and prioritizing ethical business practices.

In 2019, the Ethisphere Institute honored 128 companies from 21
countries and 50 industries. These companies illustrate how companies
can be a driving force for improving communities, building capable and
empowered workforces, and fostering corporate cultures focused on ethics
and a strong sense of purpose.

“We’re honored to be included again on the Ethisphere Institute’s
distinguished list,” said Ava Harter, Owens Corning general counsel.
“For Owens Corning employees, this is an important recognition of our
ongoing commitment to integrity and the highest standards of conduct in
everything we do.”

Methodology & Scoring

The World's Most Ethical Companies assessment is based upon the
Ethisphere Institute’s Ethics Quotient® (EQ) framework, which offers a
quantitative way to assess a company’s performance in an objective,
consistent and standardized manner. The information collected provides a
comprehensive sampling of definitive criteria of core competencies
rather than all aspects of corporate governance, risk, sustainability,
compliance and ethics.

Scores are generated in five key categories: ethics and compliance
program (35 percent), culture of ethics (20 percent), corporate
citizenship and responsibility (20 percent), governance (15 percent) and
leadership and reputation (10 percent). All companies that participate
in the assessment process receive their scores, providing them with
valuable insights into how they stack up against leading organizations.
