Munich, June 3, 2026 – HELIOS SOLAR AG (“HELIOS SOLAR” or the “Company”), an international group specializing in photovoltaic solutions with a focus on Southeast Asia, has published its securities prospectus for the planned application for admission to trading on the regulated market (General Standard) of the Frankfurt Stock Exchange. Through the IPO, the Company intends to accelerate its growth strategy, particularly the expansion of its business activities in Europe, and sustainably strengthen the financing of its international solar projects.

The offering comprises a public offering of up to 7.6 million shares at an offering price of EUR 4.00 per share. The subscription period is expected to commence on June 22, 2026, and end on July 6, 2026. The first trading day of the shares on the General Standard of the Frankfurt Stock Exchange is planned for July 28, 2026.

Access to Capital Markets as a Foundation for Further Growth

By listing its shares, HELIOS SOLAR aims to improve access to European capital markets, increase the Company’s financial flexibility, and enhance its visibility among institutional and retail investors.

“The planned IPO represents a significant milestone in the development of our group. Admission to the regulated market of the Frankfurt Stock Exchange will provide the foundation for advancing our international expansion and further strengthening our position as an innovative provider of solar solutions,” said Dato' Ong Thuan Ming, Chief Executive Officer of HELIOS SOLAR AG.

Expected Net Proceeds of Approximately EUR 26.9 Million

Assuming full placement of all offered shares, the Company expects net proceeds of approximately EUR 26,874,575.00.

The proceeds are intended to be used specifically to implement the Company’s international growth strategy:

• 58.8% of the net proceeds will be allocated to further expansion in Malaysia, including strategic partnerships with Public Islamic Bank Berhad and Boost Bank Berhad, as well as the establishment of a Training & Innovation Center.
• 32.5% of the net proceeds will be used to expand operations in Germany and Europe, including the development of two solar projects in Bulgaria.
• 5.0% of the net proceeds will be allocated to the expansion of the solar business in Cambodia, particularly in connection with a planned cooperation for financing residential solar installations.
• 3.7% of the net proceeds will be used to further expand activities in Singapore.

Solar Energy Is Gaining Strategic Importance in Europe

The IPO takes place in a market environment characterized by a long-term increase in demand for renewable energy. Europe is pursuing ambitious climate targets and investing heavily in the expansion of an independent, sustainable, and competitive energy supply. In addition to the ongoing electrification of industry, buildings, and transportation, the rapid development of artificial intelligence, cloud applications, and data centers is driving a significant increase in electricity demand. International technology companies and data center operators are increasingly relying on renewable energy sources to achieve their net-zero targets and sustainably meet growing energy requirements.

Today, photovoltaic energy is among the most economically attractive and rapidly scalable forms of power generation and is increasingly evolving into a key technology at the intersection of the energy transition, digitalization, and economic growth. At the same time, demand is rising for integrated solutions combining solar energy, energy storage, and intelligent load management. HELIOS SOLAR believes that, based on its many years of experience in developing and implementing photovoltaic projects and its international presence, it is well positioned to benefit from these structural growth trends in Europe and Asia.
