OAKVILLE, ON – August 10, 2023 - Algonquin Power & Utilities Corp. ("AQN", “Algonquin” or the “Company”) (TSX/NYSE: AQN) today announced that energy industry veteran Christopher Huskilson, a member of the Algonquin Board of Directors (the “Board”) since 2020, has been appointed Interim Chief Executive Officer, effective immediately. He succeeds Arun Banskota, who has stepped down as President and Chief Executive Officer and as a member of the Board, effective immediately.

The Board has engaged a nationally recognized search firm to commence a search process to identify a permanent Chief Executive Officer.

“As AQN prepares to pursue a sale of its renewables business and move forward as a pure-play regulated utility company, the Board of Directors has determined that now is the right time to transition leadership,” said Kenneth Moore, Chair of the Algonquin Board of Directors. “Chris has a record of driving significant growth in the energy industry, and he knows AQN and our business well from his tenures on the AQN Board. As we conduct a search for a permanent CEO, we are confident that Chris will ensure a smooth transition while we pursue a sale of the renewables business and position AQN’s utility business for its next phase of standalone growth and value creation.”

Kenneth Moore continued, “On behalf of everyone at AQN, I want to thank Arun for his leadership and contributions throughout his tenure. Arun guided AQN through the pandemic and built on the legacy of AQN’s founders over his three years as CEO, and we wish him the best in his future endeavors.”

“It is a privilege to serve as Interim CEO at this critical juncture for the Company after having chaired the Strategic Review Committee of the Board,” said Chris Huskilson, Interim CEO. “As we begin the sale process for the renewables business, our focus remains on executing our value-creation strategies and operating efficiently across both our regulated and renewable asset base. I look forward to working with the Board and management team during this transition period to build on all the work underway to re-establish AQN as a top tier utility business and unlock value for shareholders.”

Arun Banskota said, “I am proud to have had the opportunity to serve Algonquin over the past three years and believe that the Company is well positioned to deliver long-term, sustainable value for years to come.”

In a separately issued press release, the Company provided an update on its previously announced strategic review of its renewables business and announced that its Board of Directors will pursue a sale of its Renewable Energy Group. The Company also reported second quarter 2023 earnings. AQN will hold an earnings conference call at 8:30 a.m. eastern time this morning, hosted by Interim Chief Executive Officer, Chris Huskilson, and Chief Financial Officer, Darren Myers.
