Calgary, Alberta -- Questerre Energy Corporation ("Questerre" or the "Company")
announced today that the Company's Series 2 Preferred Shares (the "Preferred
Shares") have been admitted to trading on Euronext Growth Oslo under the ticker
"QGAS". The Preferred Shares commence trading today. There are approximately
45.2 million Preferred Shares outstanding following the 10:1 consolidation
approved by shareholders on June 23, 2026.

The Preferred Shares track the economic performance and value of the Company's
Quebec assets, including its significant natural gas discovery in the Quebec
Utica shale, among the largest undeveloped natural gas resources in North
America in a premium natural gas market.

Michael Binnion, President and Chief Executive Officer of Questerre, commented,
"Today's listing gives investors direct, tradeable exposure to our Québec
discovery for the first time. Until now, this asset was part of our portfolio of
assets. QGAS changes that. This reorganization marks an important step in
recognizing the underlying value of our Quebec business. The new structure
enables greater transparency and a more market-based valuation of this
opportunity."

He added, "Our Quebec business is based on a substantial natural gas discovery
in the St. Lawrence Lowlands, built over more than 20 years of investment and
representing a significant potential source of low-emissions energy. Following
the adoption of Bill 21 in 2022, the Government of Quebec asserted that it has
revoked the Company's exploration licences preventing development of the
resource. We are challenging the constitutionality of this revocation. We
anticipate the setting of a hearing date late next year or early the following
year."
