Syntholene Energy Corp Commences Trading on Frankfurt Stock Exchange Under Symbol '3DD0'

Listing Positions Syntholene as the First Publicly Traded Pure-Play Synthetic Fuel (eFuel) Company on any European Exchange

Syntholene Energy CORP (TSXV: ESAF,OTC:SYNTF) ("Syntholene" or the "Company") announces that the Company's common shares have been approved for listing and have commenced trading on the Frankfurt Stock Exchange (Frankfurter Wertpapierbörse) under the trading symbol FSE: 3DD0. The Frankfurt co-listing is intended to broaden the Company's European investor audience and increase visibility within one of the world's most important clean energy and synthetic sustainable aviation fuel (eSAF) markets.

The Frankfurt Stock Exchange is one of the largest and most liquid securities markets in Europe, and serves as a primary access point for European institutional and retail investors. The Company's primary listing remains on the TSX Venture Exchange under the symbol ESAF.

"Listing on the Frankfurt Stock Exchange is a strategically important step for Syntholene," stated Syntholene CEO Dan Sutton. "Europe is the center of global eSAF and eFuel markets today through its mandated demand, and policies encouraging market growth. Providing European investors with direct access to our shares aligns our capital markets strategy with the strongest structural tailwinds for eSAF. We view this as a natural extension of our TSXV listing and a foundation for long-term engagement with European stakeholders as we drive deployment of production infrastructure within the European Economic Zone."

Syntholene believes the Frankfurt co-listing supports the Company's presence and investor access in Europe, which is an important market for eSAF. The European Union's ReFuelEU Aviation Regulation mandates rising sustainable aviation fuel blending requirements across all major EU and European Economic Zone airports beginning in 2025 (EASA). These binding requirements, combined with targeted eSAF subsidies of up to €6 per liter (Reuters) for qualifying synthetic fuels, create one of the world's most robust and durable demand frameworks for producers of next-generation eFuels.

eFuel Market

Synthetic aviation fuel is a clean, drop-in-ready jet fuel made from renewable power, green hydrogen, and captured CO₂, offering up to 90% lower lifecycle emissions and helping airlines meet global decarbonization mandates without changing their aircraft engines or retrofitting.

The broader global aviation fuel market size was valued by Fortune Business Insights at USD 391.23 billion in 2023 and is projected to grow from USD 431.70 billion in 2024 to USD 819.73 billion by 2032, exhibiting a CAGR of 8.35% during the forecast period (Fortune Business Insights).

According to a report by MarketsandMarkets, the global sustainable aviation fuel market is projected to expand from an estimated USD 2.06 billion in 2025 to approximately USD 25.62 billion by 2030, representing a compound annual growth rate (CAGR) of about 65.5%.

Within these projections lies the ReFuelEU Aviation Regulation, the European Union's landmark mandate requiring airlines and fuel suppliers to adopt sustainable aviation fuel (SAF) at all major EU and EU Economic Zone airports starting in 2025. The regulation sets binding, rising SAF blending requirements of 2% in 2025, 6% in 2030, 20% in 2035 and up to 70% by 2050, creating one of the world's largest guaranteed markets for clean jet fuel (EASA).

The EU has also paired this demand-side measure with a supply-side subsidy, offering up to 6€ per liter to airlines that purchase eSAF specifically (Reuters). The combination of mandated demand and subsidized supply underscores the EU's seriousness about bolstering the rapid scale-up of eSAF production from producers like Syntholene.
