GIBSON ENERGY ANNOUNCES 2024 KEY INDUSTRY-LEADING SUSTAINABILITY ACHIEVEMENTS AND SAFETY LEADERSHIP

Gibson Energy Inc. has highlighted the significant progress in its annual sustainability performance. The company's exceptional operational management and safety commitment to achieve zero harm to people, the environment and assets is foundational to these efforts. Two thousand twenty-four marked the company's latest safety leadership milestone by recording 8.8 million hours without a lost-time injury for its employee and contract work force.

"Sustainable practices and operational safety will always be embedded into our day to day, and I'm proud of our team reaching this latest safety milestone," said Curtis Philippon, president and chief executive officer. "Looking broadly at our sustainability commitments, to be externally recognized by key global rating agencies, including the A minus we recently received from the Climate Disclosure Project, scoring 96 out of 100 points in the Globe and Mail board games governance ranking and placing in the 97th percentile of all energy companies by the S&P Global Corporate Sustainability Assessment, reinforces the progress we made this year. Our focus will not change in 2025: We remain committed to safety, innovation, collaboration and accountability as we continue to work toward our ambitious goals."

Gibson's sustainability strategy is built on strong governance and strategic initiatives that focus on long-term value for shareholders, employees, communities, indigenous peoples, governments, customers and suppliers.

"On behalf of the management team, I'd also like to extend sincere thanks to our employees for their commitment to safety and our sustainability goals," said Riley Hicks, senior vice-president and chief financial officer. "We will continue to build off this momentum, further leverage our world-class asset base and identify additional strategic growth opportunities to meet the evolving global energy demands."
