XCF Global CEO Highlights Renewable Energy Security as Cornerstone of Scaling Sustainable Aviation Fuel at Advanced Bioeconomy Leadership Conference, ABLC2026

Houston, TX – March 23, 2026 - XCF Global, Inc. (“XCF”) (Nasdaq: SAFX) a leading innovator in decarbonizing the aviation industry through Sustainable Aviation Fuel (“SAF”) today shared key takeaways from CEO, Chris Cooper’s presentation at the Advanced Biofuels Leadership Conference (ABLC2026) in Washington, D.C earlier this week. In his remarks, Cooper underscored renewable energy security as one important factor shaping the future of aviation decarbonization, positioning SAF as both an emissions reduction solution and a strategic national priority.

Renewable Energy Security

Cooper highlighted XCF Global’ s use of U.S. waste-based feedstocks, noting that domestic sourcing strengthens national energy resilience and reduces exposure to volatile global supply chains. The company’s strategy emphasizes supporting domestic supply chains and domestic production enhancing renewable energy security.

Modular, Scalable, and Replicable Infrastructure

XCF’s modular, scalable facility is designed to enable faster deployment, efficient replication across U.S. regions, and production capacity that grows with domestic demand without overbuilding.

Strategic Logistics Enhance Reliability

We believe the company’s logistics advantages, including proximity to major aviation markets and access to on-site rail and trucking infrastructure, can improve reliability and efficiency while minimizing transport emissions.

Immediate Deployability of SAF Strengthens Energy Stability

We believe SAF is fully compatible with existing aircraft, engines, and airport infrastructure, with the goal of enabling immediate improvements in energy stability and emissions performance without waiting for long-term technology transitions.

Following the discussion of SAF’s immediate compatibility with existing aircraft and XCF Global’ s strategy to scale domestic, waste-based feedstocks and modular production capacity, CEO Chris Cooper highlighted SAF’s unique multi-value role in the aviation energy transition. He emphasized that sustainable aviation fuel not only serves as a drop-in propulsion solution but also has the capacity to deliver emissions reductions and strengthen long-term U.S. renewable energy security.

“Sustainable aviation fuel delivers more than propulsion; we believe it can deliver emissions reductions and strengthens renewable energy security. By using U.S. waste-based feedstocks and deploying modular, scalable facilities close to major aviation markets, we are striving to build a domestic SAF system that is reliable, repeatable, and ready now. This is how we hope to provide airlines with a drop-in solution that reduces emissions and fuels flights today while reinforcing the nation’s long-term energy resilience.” Chris Cooper, CEO of XCF Global

Middle East Conflict Exposes America’s Aviation Fuel Vulnerability: XCF Global Highlights the Case for Domestic Sustainable Aviation Fuel

Houston, TX – March 23, 2026 - XCF Global, Inc. (“XCF”) (Nasdaq: SAFX) a U.S. based sustainable aviation fuel (SAF) producer decarbonizing the aviation industry today issued a statement on the ongoing disruption to global aviation fuel markets caused by the Middle East conflict. As jet fuel and SAF prices surge to historic levels, XCF Global is sharing its perspective on what the current crisis reveals about the structural vulnerabilities of petroleum-dependent aviation fuel supply chains and the role domestic SAF can play in addressing them.

According to S&P Global Platts data, SAF prices in California reached an all-time high of 885 cents ($8.85) per gallon in the week ended March 4, 2026, a surge of more than 132 cents ($1.32) per gallon in a single week. Spot jet fuel prices on the US West Coast increased to 125.54 cents ($1.26) per gallon in early March; levels not seen since 2022. The disruption of tanker disruption of tanker traffic through the Strait of Hormuz, through which approximately 20 million barrels per day of crude and refined product normally flow, has driven distillate prices sharply higher across major global hubs.

XCF SAF utilizes domestic waste-based feedstock. These feedstocks are not impacted by the Middle Eastern crude supply. “Our focus remains on delivering high quality SAF to our partners, maintaining operational continuity, and supporting the aviation sector as markets stabilize. America’s aviation sector remains deeply tethered to a global oil market that is inherently unstable. The feedstock, the technology, and the workforce to change that exist right here at home. Domestic waste-based SAF is not a future solution. We believe it can be made available now, that it can be scalable, and that it can be produced entirely from American materials. We believe the current crisis is bringing long-overdue attention to what domestic SAF producers have understood for years; a fuel whose supply chain begins and ends in the United States is a fundamentally different kind of energy security while mitigating climate impact” Chris Cooper, Chief Executive Officer, XCF Global

XCF Global believes that energy security and lowering emissions from aviation are not mutually exclusive. The events of recent weeks have brought that principle into focus for the aviation sector. As the market works through this period of volatility, XCF Global remains committed to expanding its domestic production.
