Quebec confirms strategic role for natural gas in long-term energy plan

Calgary, Alberta – Questerre Energy Corporation (“Questerre” or the “Company”) (OSE: QGAS) today commented on the Government of Quebec’s Integrated Energy Resource Management Plan (“PGIRE” or the “Plan”) for 2026–2050, published earlier this month.

The Plan inventories the province’s future energy supply. It confirms that natural gas will remain part of Quebec’s energy mix and will play a strategic role as the province gradually decarbonizes its energy system. The PGIRE states: “Natural gas remains part of the energy mix and will need to be decarbonized in a gradual and orderly manner. The ability to leverage natural gas distribution infrastructure to achieve decarbonization over time gives this energy source a strategic role.”

Michael Binnion, President and Chief Executive Officer of Questerre, commented: “The Government has recognized that natural gas will remain an important part of Quebec’s energy system for decades. This is positive for our Utica natural gas discovery and confirms the continuing importance of reliable gas supply during the energy transition.”

He added: “While the PGIRE does not mention the Utica gas discovery, polls show Quebecers prefer locally produced natural gas over imports from the United States. Our local natural gas would have a lower greenhouse-gas emissions footprint than the gas Quebec currently imports from the United States.”

Questerre believes its Utica discovery offers Quebec a shovel-ready opportunity to strengthen energy security, reduce dependence on imports and supply locally produced natural gas with a lower emissions footprint.

The PGIRE was introduced under Bill 69, An Act to ensure the responsible governance of energy resources and to amend various legislative provisions, adopted in June 2025. It establishes Quebec’s long-term policy directions, objectives and targets for electricity and natural gas supply, energy infrastructure and innovation.

Questerre is an energy technology and innovation company focused on responsibly developing oil and gas resources. The Company holds a significant natural gas discovery in the Quebec Utica shale, widely recognized as one of the most important undeveloped natural gas resources in Eastern Canada. The Company believes society can successfully transition its energy portfolio. With new clean technologies and innovation to responsibly produce and use energy, society can sustain both human progress and the natural environment.

Questerre is a believer that the future success of the energy industry depends on a balance of economics, environment, and society. We are committed to being transparent and are respectful that the public must be part of making the important choices for our energy future.
