DevvStream Affiliate Monroe Sequestration Partners Signs Agreement with Southern Energy to Anchor Major Carbon Capture Project in Louisiana

DevvStream's October 2024 acquisition of 50% of the common interests in Monroe Sequestration Partners directly connects the Company to one of the Gulf Coast's most strategic carbon storage and clean fuel sectors

CALGARY, Alberta, May 8, 2025 - DevvStream Corp. (Nasdaq: DEVS) ("DevvStream" or the "Company"), a leading carbon management firm specializing in the development, investment, and sale of environmental assets, today announced that Monroe Sequestration Partners ("Monroe"), in which DevvStream acquired a 50% common-interest stake in October 2024, has signed a Collaboration Agreement (the "Agreement") with Southern Energy, a Wyoming-based clean fuels company proposing the development of a $1 billion (USD) methanol and sustainable aviation fuel ("SAF") facility in Louisiana.

The Agreement outlines a strategic partnership in which Monroe would provide permanent CO₂ sequestration through its Class VI storage site, expected to be operational in 2027, while Southern Energy would capture emissions from its planned biomass-to-fuel facility, targeting production in 2028. The parties aim to generate high-quality carbon credits and support compliance with global decarbonization mandates in aviation and maritime transport industries. The Company anticipates entering into additional definitive binding agreements reflecting the terms outlined in the Agreement during Q2 of this year.

"Monroe's combination of Class VI storage readiness, local access, and commercial reach positions it among the most advanced carbon storage developers in the country," said Carl Stanton, Chairman of DevvStream. "Louisiana is quickly becoming the carbon capture capital of the U.S., and this agreement underscores Monroe's leadership in delivering durable, monetizable carbon removal solutions."

About Southern Energy's Project

Southern Energy plans to build a biomass-to-fuel facility in Louisiana to produce low-carbon methanol and SAF with an anticipated project cost of approximately $1 billion. Using proven syngas technology and a large-scale regional feedstock strategy, the facility is designed to serve both maritime and aviation sectors. Integrated carbon capture is expected to drive exceptionally low lifecycle carbon intensity ("CI") scores while generating 45Q tax credits and other monetizable environmental assets.

The facility is expected to benefit from Northern Louisiana's location within the Southern Wood Basket-the largest biomass-producing region in North America. According to market studies, the North Louisiana-South Arkansas corridor ranks among the top five U.S. markets for pulpwood and forest residual availability, providing secure, scalable access to sustainably sourced feedstock.

"Southern Energy's platform aligns directly with recent federal initiatives supporting clean energy infrastructure," added Sunny Trinh, CEO of DevvStream. "The combination of permanent sequestration, proven fuel tech, and policy momentum makes this a standout project."

Strategic Importance of Louisiana

Louisiana is emerging as a national hub for carbon capture and storage ("CCS"). As one of only four states with U.S. EPA-approved primacy over Class VI wells, it can independently permit carbon storage projects-potentially cutting years off timelines. According to Bloomberg (April 2025), over a dozen CCS projects are already underway across the state, backed by more than $4.5 billion (USD) in anticipated investment.

Recent federal policy changes have the potential to increase this momentum. The current administration's first 100 days brought a sweeping realignment around CCS-executive orders prioritized permitting, expanded 45Q incentives, and encouraged private-sector deployment. Monroe's early position and deep ties in Louisiana provide a unique potential advantage as demand for durable carbon removal grows.

Strategic Implications for DevvStream

For DevvStream, this Agreement has the potential to strengthen its infrastructure-backed carbon credit pipeline and to deepen its exposure to permanent sequestration revenues. As co-owner of Monroe, DevvStream is expected to support project development, credit packaging, and long-term monetization efforts.

This Agreement also reinforces DevvStream's broader investment strategy: leveraging partnerships with industrial emitters to scale environmental asset generation under favorable policy, geographic, and commercial conditions.

About DevvStream

Founded in 2021, DevvStream is a leading carbon management firm specializing in the development, investment, and sale of environmental assets, energy transition, and innovative carbon management solutions. 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 energy transition and carbon markets, 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 or renewable energy generation in exchange for a percentage of generated credits or I-RECs.
