Haffner Energy's Stock Soars by 10%, Marking a +227% Increase Over Three Months

Haffner Energy continues its rally, closing this Thursday, May 21, 2026, at €0.1628, up from €0.148 the previous day. The daily gain of 10% extends a strong medium-term momentum, with the stock price still at a lower level in February. This session follows the recent completion of a convertible bond financing with Hanover Square Investments 1.


Haffner Energy's Stock Soars by 10%, Marking a +227% Increase Over Three Months

A Spectacular Medium-Term Momentum Contrasting with the Annual Performance

Haffner Energy has shown a 227.2% increase over three months, a surge that positions the stock price well below its moving averages. However, the weekly performance has declined by 2.39%, indicating a consolidation after several waves of increase. Over one year, the stock still shows a decline of 38.26%, reflecting the progress made from the lows.
The movement follows the completion of the convertible bond financing with Hanover Square Investments 1, with the last tranche of €1.09 million drawn. In total, 218 convertible bonds were converted, resulting in the creation of 12,517,225 new shares. The company had previously highlighted the risks of dilution and downward pressure on the stock price associated with this mechanism.
The sector context remains favorable for clean technologies and hydrogen, a sector in which the memorandum of understanding with Maharashtra, signed on April 16, positioned Haffner Energy in a project involving approximately €15 billion in investments spread across four infrastructure projects, two of which are based on its technologies.

The stock price is above the technical resistance identified at €0.17. The stock is trading 48% above its MM20 (€0.11) and more than 132% above its MM50 (€0.07), a gap that reflects the magnitude of the movement initiated since February. The MM200 at €0.15 has been surpassed upward, with the price now 8.53% above this long-term reference.
The RSI at 65 remains below the classic overbought threshold, without signaling immediate exhaustion. The one-month volatility is high, at 41.78, consistent with the amplitude of recent sessions on the stock.
The technical resistance at €0.17 is the immediate marker to watch in the coming sessions to validate or not the continuation of the movement.
