• Carbon Management Program by SEER and DevvStream will be centered around biogas capture and carbon sequestration through biocarbon, or biochar, production
• Companies plan to leverage over 150 existing SEER-affiliate biogas installations across North America with numerous multinational utility companies, food processors, brewers, and agriculture firms as well as future large-scale projects in the US and in the Kingdom of Saudi Arabia
• In addition to biogas and biocarbon production, the Program will also enable the generation of carbon credits from oil field emission reductions and sequestration projects

DevvStream Corp. (NASDAQ: DEVS) ("DevvStream" or the "Company"), a leading carbon credit project co-development and generation firm specializing in technology-based solutions, and Strategic Environmental & Energy Resources, Inc. ("SEER"), a leading provider of environmental services, renewable fuels, and industrial waste management solutions, today announced a Carbon Management Program (the "Program") established to quantify and monetize high-quality carbon credits derived from SEER's cutting-edge technologies and projects, with a primary focus on biogas capture. Entry into the biogas industry expands the Company into an estimated $10 billion market in the United States, forecast to surpass $15 billion by 2030. The Program represents a new advancement in the Project Development category of DevvStream's three-tiered corporate strategy and is expected to begin generating revenue in 2025 via sales of biochar credits and technology-based carbon credits. DevvStream will retain a portion of the revenue from credits generated and sold.

The Program will focus on three key areas:

1. Biogas Capture and Conditioning - Generating methane renewable energy through advanced proprietary biogas capture and treatment.
2. Mitigation of Fugitive Emissions - Reducing harmful emissions from small vertical oil and gas wells using SEER's patented technologies.
3. Carbon Sequestration - Establishing biocarbon production facilities in Texas and Saudi Arabia to capture and sequester CO2 effectively. Credits created from biochar are currently priced in excess of $125, according to market participants.

SEER's MV Technologies, LLC ("MV") subsidiary deploys two primary decarbonization technologies: (a) a patented Variable Volume Vapor Recovery Unit ("V3RU") technology for vapor recovery in oil fields, and (b) a proprietary biogas conditioning system ("BCS"). MV currently has over 150 installations of its BCS solution across North America at renewable natural gas and landfill facilities, serving some of the nation's largest utility companies, food processors, brewers, landfills, and agriculture firms.

The Program also builds on SEER's successful initiatives in Saudi Arabia, including its participation in the Green Riyadh project, one of the largest urban afforestation projects in the world, as well as its work with Eco Tadweer, an initiative of the Saudi Economic Cooperation Organization led by the private sector to contribute to national and global efforts in the field of environmental sustainability and, more specifically, the application of a circular carbon economy approach as envisioned by the Saudi Investment Recycling Company.

"SEER has developed and maintained a world-class customer base through the deployment of its advanced decarbonization technology portfolio," said Sunny Trinh, CEO of DevvStream. "The relationships SEER has established and the trust they have earned through proven successes in the field provide an immediate opportunity to create and monetize high-quality carbon credits on a substantial scale. The Program enables us to generate measurable environmental benefits and strong financial results for all shareholders in both the short and long term."

"SEER's innovative technologies perfectly complement DevvStream's growth strategy," said John Combs, CEO of SEER. "The Program allows us to expand the deployment of the V3RU system, quantify its environmental impact, and unlock valuable carbon credit opportunities for our customers within the biogas and RNG sectors. Our relationship with DevvStream represents a significant step in SEER's commitment to decarbonization and to the creation of value for our stakeholders."

"The Program developed by SEER and DevvStream will complement the ongoing environmental and financial success of Eco Tadweer in the Kingdom," said Areej Alturki, President of Eco Tadweer. "As we continue to scale biocarbon production and enhance our decarbonization programs and environmental impact, we are committed to maximizing the monetization of carbon credits and look forward to working with SEER and DevvStream to create maximum value for our Saudi stakeholders."
