HELIOS SOLAR AG announces that the subscription period for its planned initial public offering (IPO) on the Regulated Market (General Standard) of the Frankfurt Stock Exchange will now commence on June 29, 2026, and is expected to run until July 13, 2026. The subscription period had previously been scheduled to begin on June 22, 2026.

This adjustment has been made to provide additional subscription opportunities for investors. As a result, a supplement to the securities prospectus will be required. The measure is intended to broaden access to the IPO for a wider range of investors and to further optimize the placement process.

The management of HELIOS SOLAR AG will be present at Intersolar Europe 2026 in Munich from June 23 to June 25, 2026, the leading international trade fair for the solar industry. During this period, the Company will engage in intensive discussions with institutional investors, strategic partners, and other market participants.

The additional time gained through the revised schedule will be used to deepen these relationships and provide interested investors with further opportunities for direct dialogue with the management team. The remainder of the IPO timetable remains unchanged. The planned listing on the Frankfurt Stock Exchange is still expected to take place within the original IPO schedule, with the first day of trading anticipated on July 28, 2026.

Ong Thuan Ming, Chief Executive Officer of HELIOS SOLAR AG, commented: “The extension of the subscription opportunities provides investors with additional flexibility and increases the reach of our offering. Intersolar also offers an excellent platform to present HELIOS SOLAR AG to a broad audience and investor base. The timing adjustment allows us to make the most of these opportunities without affecting the overall IPO process.”
