AltaGas Ltd. has appointed a new independent director, Jon-Al Duplantier, effective today. Allan Edgeworth will retire from the board, effective upon the conclusion of the company's next annual general meeting of shareholders, to be held in late April of this year.

Mr. Duplantier is a recently retired executive who comes with more than 25 years of experience across the energy value chain. Most recently, Mr. Duplantier served as president of rental tools and well services at Parker Drilling and was previously senior vice-president, chief administrative officer and general counsel within Parker. Prior to joining Parker, Mr. Duplantier spent more than a decade with ConocoPhillips, which spanned a number of senior legal, commercial and environmental roles that included posts across the United States, Indonesia and the United Arab Emirates. Mr. Duplantier holds a juris doctor degree from Louisiana State University and bachelor of science from Grambling State University.

"I am very pleased to welcome Jon-Al to our board," stated Pentti Karkkainen, chair of the board of AltaGas. "Jon-Al not only brings a wealth of experience as a business leader but also a natural intellectual curiosity that will enrich the character and depth of discussion at the board. He brings with him career experiences across a range of disciplines spanning across complex regulatory settings that will be of significant benefit to all our stakeholders." Mr. Duplantier will also serve as a member of the company's governance committee.

Mr. Edgeworth joined the board in 2005. He brought his extensive industry knowledge to his service on the board in a variety of roles over that time. He currently serves as a member of the audit committee and is chair of the human resources and compensation committee. Previously, Mr. Edgeworth served as the chair of the environment, health and safety committee, where he played a leadership role in shaping the company's culture of safety and environmental responsibility.

"On behalf of the board of directors and all our stakeholders, I want to thank Al for his substantial contributions during his tenure. He has been a very valued member of the AltaGas team over the past 15 years and will be missed," said Mr. Karkkainen.

Following Mr. Edgeworth's planned retirement, the company's board will revert to comprising 11 directors, with Nancy Tower assuming the role of chair of the human resources and compensation committee.
