XCF Global, Southern Energy, and DevvStream Announce Plan to Pursue Strategic Collaboration to Build Integrated Low-Carbon Fuels Platform and Advance Multi-Pathway SAF Strategy

• XCF, Southern Energy, and DevvStream to explore developing a unified commercial platform combining fuel supply, logistics, and environmental-attribute value for aviation and industrial customers

• The parties believe that the partnership has the potential to advance HEFA and next-generation biomass-to-methanol-to-jet SAF pathways

The parties intend to jointly evaluate the future development of New Rise Louisiana, a SAF facility comparable in size to XCF's New Rise Reno facility of ~40 million gallons

HOUSTON, TX / ACCESS Newswire / December 12, 2025 / XCF Global, Inc. ("XCF") (Nasdaq:SAFX); Southern Energy Renewables Inc. ("Southern"); and DevvStream Corp. ("DevvStream") (Nasdaq:DEVS) (together "the parties") today announced a non-binding tripartite memorandum of understanding ("MOU") to jointly explore the potential development of a next-generation low-carbon fuels platform designed to accelerate SAF adoption, expand domestic capacity, and integrate environmental-attribute monetization into a unified customer offering.

By 2030, the U.S. SAF market is projected to reach nearly $7 billion, while global demand is expected to exceed 5.5 billion gallons, supporting a global market of more than $25 billion. By that time, approximately 4 billion people are expected to live in countries that utilize SAF for air transportation. Looking ahead to 2050, the global SAF market could exceed $250 billion. This collaboration is intended to position the parties around a unified platform that directly supports this long-term growth.

The collaboration would seek to increase long-term SAF supply across multiple production pathways while advancing the transparency and commercialization of environmental attributes. As part of the negotiation of a binding agreement, the parties expect to evaluate the commercial viability of developing a HEFA-based SAF facility in Louisiana.

Potential Unified Commercial Platform and Strategic Integration

The parties intend to negotiate a definitive collaboration agreement which, if executed, would create a collaborative venture that intends to develop a unified commercial platform that enables customers to procure fuel, logistics services, and environmental-attribute value through a single integrated offering. If developed, this structure would be expected to simplify procurement, improve pricing efficiency, and enhance long-term customer retention across the aviation and industrial markets.
