A LETTER FROM OUR CEO AND THE COMPLIANCE OFFICER

Hello Southwesters:
Southwest Gas has always embraced a corporate culture based upon honesty, compliance,
and strong ethical standards. As part of the Company’s ongoing pledge to maintain a work
environment based on these principles, the Company’s Code of Business Conduct and Ethics
(“Code”) was recently updated. While the Code may have a new look, the Company’s
commitment to quality and compliance has not changed.
The Code signifies the Company’s corporate accountability built on the dedication of our
employees to conduct business with integrity, respect, dependability, ethics, and honesty for
one another, our stakeholders, and our communities. It is essential for all of us to follow
these principles, every day in every way, in order to maintain the excellent reputation we
have created together. It is also important to recognize our obligation to report any
compliance concerns or Code violations.
The Code is a key resource for finding answers when faced with challenging questions
regarding day-to-day decision making. Please take time to read and understand the Code
and allow the core values to guide your daily decisions and actions. If you need clarification
on any issues covered in the Code, please contact one of the Internal Resources listed at the
end of this document.
We are all in this together. Please know that the Company’s Board of Directors and
management continue to be committed to the highest ethical standards and ask that you
continue to commit to the same. We are proud to be Southwesters and appreciate your
efforts in TAKING THE TIME TO MAKE IT RIGHT.
