Calgary, Alberta--(Newsfile Corp. - June 20, 2025) - DevvStream Corp. (NASDAQ: DEVS), a leading carbon management firm specializing in the development, investment, and sale of environmental assets, today announced a carbon-management agreement with Energy Efficient Technologies ("EET"). EET is an engineering firm that reduces electricity use in commercial buildings by an average 8%-35% and has validated savings for numerous large-scale clients, including a global hospitality group operating more than 8,000 hotels across more than 130 countries, the world's largest quick-service restaurant network, and one of the world's largest brewing companies, with flagship beer brands sold in over 100 markets.

Deal highlights

• Two revenue streams. Pursuant to the agreement, DevvStream will receive revenue from EET's carbon credits and international renewable energy certificates ("I-RECs") and share in verified utility-bill savings.
• New vertical. Adds building-efficiency assets to DevvStream's hydro, solar, waste-to-energy, carbon-capture, and biogas portfolio of projects and partners.
• Large addressable market. EET estimates that deploying its CryoGenX4™ across 8,000 data centers could save (US) $20 billion in power costs, cut 166 billion kWh, and avoid 117 million tonnes of CO₂ per year—showing the scale DevvStream can help monetize.
• Growing demand. Companies seeking scope-2 reductions increasingly view energy-efficiency credits as a cost-effective decarbonization path.

"We believe EET's proven record of double-digit energy savings positions us to unlock a high-value stream of efficiency-based credits and cost-sharing revenue," said Sunny Trinh, CEO of DevvStream. "By layering shared savings on top of carbon- and I-REC monetization, we anticipate further diversifying DevvStream's income while helping businesses cut costs and emissions."

"Energy Efficient Technologies has delivered—and independently verified—double-digit energy-use reductions for clients such as Marriott, McDonald's cold-chain distribution network, Anheuser-Busch, and Cogent Communications data centers," said Joe Mearman, CEO of EET. "DevvStream's transparent credit-certification process and global buyer reach provide a trusted pathway to convert those proven savings into high-integrity carbon credits and I-RECs, allowing our customers to capture additional environmental and financial value while we remain focused on engineering efficiency at scale."
