August 14, 2026 – Toronto, Ontario – Base Carbon Inc. (Cboe CA: BCBN) (OTCQX: BCBNF) with operations through its wholly-owned subsidiary, Base Carbon Capital Partners Corp. (“**BCCPC**”, together, with affiliates, “**Base Carbon**”, or the “**Company**”), is pleased to announce its second-quarter 2026 consolidated operational and financial results. The Company will host an investor town hall in September, with details to follow over the coming weeks. All financial references are denominated in U.S. dollars, unless otherwise noted.

## Highlights:

- **Continued Rwanda CORSIA Sales:** The Company continues to strategically and opportunistically monetize its CORSIA-eligible¹ carbon credits. During the quarter the Company received approximately $0.4 million in cash proceeds from sales, with a further approximately $1.9 million received in cash proceeds from sales subsequent to quarter-end.

- **Full CORSIA Eligibility of Rwanda Inventory:** All carbon credits held by the Company (approximately 0.9 million) from the Rwanda cookstoves project are now designated CORSIA-eligible, following the Government of Rwanda's submission of its BTR² and Verra's subsequent tagging.

- **Vietnam Compliance Pathway – Continued Progression:** The Government of Vietnam enacted Decree No. 112/2026/ND-CP (the “**Decree**”) on May 19, 2026, an important intermediary step towards achieving approval for international sale of carbon credits generated from our Vietnam project.

- **Proposed EU Adoption of CORSIA:** On July 17, 2026, the European Commission published proposed reforms to the European Union Emissions Trading System that would embed Phase 1 and Phase 2 of the CORSIA program into EU law, as detailed in the Company's press release dated July 21, 2026. CORSIA-eligible carbon credit pricing strengthened materially following the announcement³.

- **Shareholder-focused Capital Allocation:** The Company renewed its normal course issuer bid (“**NCIB**”), commencing June 23, 2026, with authorization to purchase up to 6,264,560 common shares. Since inception, the Company has repurchased approximately 27.5 million shares in aggregate (22% of the then shares outstanding).

- **Financial Results:** The Company ended the quarter with total assets of approximately $103.4 million, including $2.3 million in cash and cash equivalents, $14.1 million in carbon credit inventory, and $2.8 million in the carbon credit revenue participation asset. The Company reported a second-quarter 2026 loss per share of $0.02.

“The second quarter reflected the steady progression of Base Carbon's business,” said Michael Costa, Chief Executive Officer of Base Carbon. “In Rwanda, we have been opportunistically monetizing CORSIA-eligible carbon credit inventories in a measured and accretive manner, and we intend to continue doing so. We believe that both pricing and volume will continue to progress positively as more global airlines begin their purchase programs for Phase 1. In Vietnam and India, regulatory and operational progress continued during the quarter, and we remain encouraged by the trajectory of both projects. Across our business, we continue to execute against a disciplined framework of capital and resource allocation, and we intend to continue utilizing our NCIB program in a value-accretive manner.”

### Rwanda Cookstoves Project

The Company continued to monetize carbon credits generated by its Rwanda cookstoves project, receiving cash proceeds of approximately $0.4 million during the quarter and an additional approximately $1.9 million subsequent to quarter-end. In recent weeks, the Company has experienced a meaningful increase in unsolicited interest from prospective purchasers of its Rwanda carbon credits following recent developments in the compliance carbon market, particularly the [European Union's proposal to embed CORSIA into EU law](https://basecarbon.com/investors/press-releases/eu-proposes-to-embed-corsia-into-law-through-2035-as-base-carbons-rwanda-inventory-becomes-fully-corsia-eligible).

During the quarter, the Government of Rwanda submitted its biennial transparency reports pursuant to the Paris Agreement, extending a corresponding adjustment to the remaining portion of the Company's carbon credit inventory. Subsequent to quarter-end, Verra applied the CORSIA-eligible designation to all of the Company's previously untagged Rwanda inventory, resulting in all carbon credits currently held by the Company being eligible for CORSIA's First Phase compliance period.

As of the date of this release, the Company holds approximately 0.9 million CORSIA-eligible carbon credits in inventory, with a further approximately 0.7 million carbon credits held by project partner, DelAgua. In addition, approximately 2.6 million future carbon credits are anticipated to be generated over regular 6-month intervals during the remainder of the project's crediting period.


### Vietnam Household Devices Project

During the quarter, the Government of Vietnam enacted the Decree, establishing the regulatory framework governing the authorization and international transfer of carbon credits under Article 6 of the Paris Agreement. The Decree represents a meaningful stepping stone for the Company's Vietnam household devices project by creating a formal pathway for corresponding adjustments and participation in international carbon compliance markets. Receipt of authorization would strengthen the project's eligibility for various compliance markets, including CORSIA and Singapore's carbon tax regime, similar to the pathway established for the Company's Rwanda cookstoves project.

Subject to the receipt of the necessary governmental approvals and the exercise of project expansion rights, the Company estimates the project could generate approximately 16.1 million carbon credits eligible for international transfer and potential compliance market use. The Company believes the project is well positioned to advance through the authorization process, and the exercise of the project expansion rights represents one of the most significant components of long-term value accretion within our portfolio.


### India Afforestation, Reforestation, and Revegetation (ARR) Project 

During the quarter, the India ARR project continued to advance, including ongoing data collection, analysis and verification work required for the project's first carbon credit issuance under Verra's VM0047 methodology, as well as preparations for the 2026 replanting season. The project remains on track for first carbon credit issuance in 2027 and continues to pursue Verra's ABACUS label.


### Investor Town Hall

The Company plans to hold an investor town hall in September where management will provide a business update and respond to investor questions via Zoom Webinar. Further details regarding the date and time as well as registration information will follow in the coming weeks.
