TORONTO, March 25, 2026 -- Base Carbon Inc. (Cboe CA: BCBN) (OTCQX: BCBNF) with operations through its wholly-owned subsidiary, Base Carbon Capital Partners Corp. (together, with affiliates, “**Base Carbon**”, or the “**Company**”), is pleased to announce the issuance of 639,609 carbon credits from the Rwanda Cookstoves Project (the “Project”), marking the fourth issuance from the Project and the first issuance of carbon credits following the successful transition of the Project to Verra’s VM0050 methodology. Upon the purchase of required insurance, the carbon credits are expected to receive Carbon Offsetting and Reduction Scheme for International Aviation (“**CORSIA”**) eligible tagging, further strengthening the Project’s inventory of high-integrity, compliance-aligned carbon credits.

The 639,609 carbon credits are held by Base Carbon’s Rwanda project partner, the DelAgua Group (“**DelAgua**”), pursuant to the Project agreement and revenue sharing arrangement. The direct generation of credits under the updated VM0050 methodology further validates the integrity of the transition and demonstrates the Project’s consistent and reliable operational performance, which the Company expects to support a regular cadence of streamlined issuances with CORSIA-eligible tagging going forward.

Upon confirmation of CORSIA-eligible tagging from Verra, the credits from this latest issuance will be immediately available for sale and delivery into global aviation carbon offsetting markets. Building on the Project’s first CORSIA-eligible tagged carbon credit sales completed earlier this year, the Company continues to engage in active sales discussions and RFP processes with prospective offtakers. Given its strong financial position and growing portfolio of eligible carbon credits, the Company intends to remain both strategic and opportunistic in its monetization approach, balancing near-term revenue generation with long-term inventory value maximization as the CORSIA compliance market continues to mature.

“Following the Project's successful transition to VM0050, this fourth issuance, and the first produced directly under the updated methodology, reflects the full maturation of the Rwanda Cookstoves Project as an asset generating CORSIA-eligible credits on a regular cadence," said Michael Costa, CEO of Base Carbon. “With our first CORSIA-eligible sales underway, an attractive supply and demand environment in CORSIA's first compliance period and expected near-term additions to our CORSIA-eligible inventory, we believe Base Carbon is well positioned within a critical component of the global compliance carbon market. Disciplined execution, opportunistic inventory monetization and recurring project production will drive continued value accretion for our enterprise and our shareholders.”
