• Site capable of storing an estimated 260 MMT of CO2
• Company will partner with Monroe Sequestration Partners to generate both 45Q federal tax credits and voluntary offset credits
• Company owns a 50% equity stake in the facility

DevvStream Corp. (NASDAQ: DEVS) ("DevvStream" or the "Company"), a leading carbon credit project co-development and generation firm specializing in technology-based solutions, and Monroe Sequestration Partners LLC ("MSP"), a subsidiary of Crestmont Investments LLC, today announced a progress update regarding the development of the previously announced MSP carbon sequestration facility (the "Monroe Project"). Designed to leverage the carbon storage capabilities of a 425-square-mile legacy oil and gas field located in northern Louisiana, the Monroe Project has the potential to become one of the largest carbon sequestration reservoirs in the United States, with an estimated total storage capacity of 260 million metric tons of CO₂.

Monroe Project Update

• Advanced engineering and geologic assessments are uncovering significant carbon emission sources, aligning with the objectives of the Louisiana Department of Natural Resources and the Federal CarbonSAFE program.

• The Monroe Project represents an ideal candidate for CarbonSAFE funding, as the program seeks to support projects with robust geologic potential and scalable development strategies.
  
  
• Multiple surface locations have been identified and prioritized for initial monitoring and injection wells, demonstrating the project's readiness for implementation.

"The Monroe Project represents a key component of DevvStream's overarching investment strategy," said Sunny Trinh, CEO of DevvStream. "The project has significant environmental impact potential as well as substantial revenue potential via the generation of 45Q credits and voluntary carbon offset credits, as well as storage fees from accepted CO₂ to be sequestered. We are proud to work with the Louisiana Oil and Gas Association, the state of Louisiana, and MSP, and we are thrilled to see development moving forward as planned."

"Louisiana is committed to carbon capture and sequestration not only for the environmental benefits, but also because it provides a new opportunity for our oil and gas producers to expand their skilled workforce and existing resources," said Bryan Hanks, board member of the Louisiana Oil and Gas Association. "By transitioning to carbon storage, we're giving these industries a path to remain viable in a cleaner energy future, helping preserve jobs, stimulate the local economy, and leverage decades of expertise in subsurface operations. Our initiative alongside MSP and DevvStream allows Louisiana to support both economic resilience and environmental progress."

Key Details About the Monroe Project

• Strategic Location: Located in Northern Louisiana's with proximity to major CO₂ emitters, creating efficient access for capturing and storing emissions.

• Economic & Environmental Impact: Supported by 45Q federal tax credits-currently sold for $85 per tonne of CO₂ stored-and the voluntary carbon market, the Monroe Project aims to deliver both significant financial returns and environmental benefits.

• Local Partnerships: Collaboration with Louisiana's oil and gas industry leaders, engineering firms, and regulatory experts creates a robust foundation for project execution.

• Job Creation and Regional Benefits: Expected to stimulate the local economy by creating jobs, supporting local businesses, and contributing to sustainable economic growth in Louisiana.

• Carbon Neutral Goals: The Monroe Project is positioned as a flagship initiative in the global push toward net-zero emissions, making a substantial contribution to emissions reduction goals.

• Future Expansion Potential: With over 500,000 acres of potential storage area, the project has ample space for additional CO₂ disposal wells and future capacity growth.

Benefits of Primacy in Louisiana

• Regulatory Advantage - Class VI Permit Primacy: Louisiana's primacy to issue Class VI permits gives it a significant edge over other states in carbon sequestration. This authority means that Louisiana can approve carbon storage projects directly through state-level regulators rather than waiting for federal EPA approval, which is often a lengthy process.

• Faster Project Approvals: With primacy, Louisiana can streamline the permitting process for Class VI wells, reducing the time it takes for projects to begin. This faster approval process allows carbon sequestration initiatives to move from planning to execution more quickly than in states without this authority.

• Lower Costs and Greater Certainty: By handling permits locally, Louisiana reduces costs and regulatory uncertainty for carbon storage developers, making it an attractive location for investment compared to states relying on federal approvals.

• Enhanced Project Scalability: Primacy allows Louisiana to scale up carbon sequestration efforts more effectively, as the state can manage and process multiple permit requests in response to demand, supporting larger and more ambitious projects.

• Supportive State Incentives: Louisiana offers incentives for carbon sequestration, making it easier to develop and sustain projects within the state.

About DevvStream

Founded in 2021, DevvStream is a leading authority in the use of technology in carbon project development. The Company's mission is to create alignment between sustainability and profitability, helping organizations achieve their climate initiatives while directly improving their financial health.

With a diverse approach to the carbon market, DevvStream operates across three strategic domains: (1) an offset portfolio consisting of nature-based, tech-based, and carbon sequestration credits for immediate sale to corporations and governments seeking to offset their most difficult-to-reduce emissions; (2) project investment, acquisitions, and industry consolidation to extend the company's reach, allowing it to become a full end-to-end solutions provider; and (3) project development, where the company serves as project manager for eligible activities such as EV charging in exchange for a percentage of generated credits.
