Haffner Energy Stock Surges 13% Following Launch of Its SB-HEFA Process
Haffner Energy recorded a marked gain on Tuesday, following the presentation of its SB-HEFA process designed to reduce the production cost of sustainable aviation fuel. The stock thus regains momentum after a difficult week, confirming the upward dynamic initiated since summer against the backdrop of a sequence of commercial and technological announcements.
SB-HEFA Launch Propels Stock Above Key Moving Averages
Haffner Energy is trading at €0.60 during the session, up 13.07% compared to the previous close of €0.528. This movement occurs on the very day of the presentation of the SB-HEFA process, a technology for producing renewable diesel and sustainable aviation fuel (SAF) based on the company's proprietary thermolysis. The company, based in Vitry-le-François, positions this new process on a model combining technology licenses and equipment supply, with the stated objective of halving SAF production costs.
The rebound occurs in a favorable stock market context: the CAC 40 gains 0.34% during the session, the DAX advances 0.94%, with the VIX remaining contained at 14.8, a sign of a market with low tension. Over three months, the stock already shows +131.4%, and +142.7% over one year, illustrating the magnitude of the rally initiated since summer.
Solid Technical Configuration Despite Neutral RSI and Distant Resistance
Technically, the price is evolving above the 20-day MA at €0.58 (spread of +2.93%) and is clearly above the 50-day MA at €0.48, which reflects an intact upward dynamic in the short and medium term. The RSI at 47 remains in neutral territory, without an immediate exhaustion signal, which leaves room before reaching the overbought zone. Resistance is identified at €0.78, approximately 30% above the current price, while support is located at €0.47. This band amplitude is consistent with elevated monthly volatility of 52.17, characteristic of a small cap in acceleration phase.
On the fundamentals side, upon publication of annual results for fiscal year 2026 on June 25, 2026, the company raised its revenue target to over €500 million and targeted a gross margin exceeding €175 million. Furthermore, the CORE100 program, whose reservation period has been extended until January 31, 2027, carries revenue potential now exceeding €500 million. The next institutional meeting is the Annual General Meeting, scheduled for September 28, 2026.
