Tonner Drones, a 18,7% shareholder, is enthusiastic about the future of ROTH2. The company has a high-level R&amp;D department. Roth2 is involved in the development of drones for long-distance flights and is preparing to scale up its operations to meet the explosively growing global demand for hydrogen and other substances that need to be stored at high pressure. Tonner Drones especially has high expectations for Roth2's revolution in high-pressure storage: the Type V tank. This technology should bring high growth and high profitibility to the company. The investment aligns with the communicated strategy that Tonner Drones aims to assist companies with its expertise in turnarounds and the equity markets. The investment in Roth2 is not just a financial one. It strengthens Tonner Drones' position in industrial technologies and could serve as a stepping stone to further operational activities. Tonner Drones has supported the company, thereby enabling the Direct Listing. The largest Roth2 shareholders have accepted a lockup, and the company has gone public at an attractive valuation compared to financing rounds (against 6 to 8 times higher valuation) in recent years. Therefore, Tonner Drones is convinced that the share price development of ROTH2 can develop very favorably. Tonner Drones is expecting trading volumes and liquidity to rise, so that continous trading will be facilitated and the company has the ambition for a transfer to Euronext Growth. Especially when the revolutionary type V technology will be certified in the coming months. This 100% recyclable composite tank represents a groundbreaking leap forward in logistics for gas transport and heavy mobility, such as trucks and buses. Tonner Drones expect huge demand for this solution. The technology will be further rolled out in 2026, and ROTH2 is well-positioned to capture a significant share of the this high pressure (including hydrogen) storage market, which is expected to reach a market size of $21.9 billion in 2032. This innovation is expected to generate substantial profitability for Roth2 in the future. ROTH2 is actively involved in the development of long-range drones. By leveraging ROTH2's expertise in ultra-high-pressure hydrogen storage, these next-generation drones aim to overcome current range limitations and provide crucial infrastructure for industrial and logistics applications. Being active in two highly dynamic sectors, ROTH2 is entering the stock market with a clear "hyper-growth trajectory," targeting a revenue increase from €5.6 million in 2024/25 to €30 million in 2029/30. <ul type="disc"><li style="margin-bottom:8pt; text-align:justify;">Market leadership: ROTH2 is currently the only French manufacturer of seamless steel tanks capable of withstanding pressures up to 1,000 bar.</li><li style="margin-bottom:8pt; text-align:justify;">Production scalability: The automated production facility in Mions is ready to scale up to a capacity of 70,000 tanks per year.</li><li style="margin-bottom:8pt; text-align:justify;">Global expansion: The company is strengthening its distribution networks in Europe and North and South America to support global energy independence.</li><li style="margin-bottom:8pt; text-align:justify;">Type V to be the leading technology for high pressure</li></ul> Roth2 will organize a webinar on Tuesday at 18:00. An Alpha Value report with valuation of €2,20 per share is available on the TonnerDrones website together with this press-release. It is Tonner Drones’ intention to support Roth2 towards future success. A strategy that Tonner Drones will consider is distributing Roth2 shares to Tonner Drones shareholders. This will benefit Roth2's liquidity, while Tonner Drones shareholders can look forward to an attractive dividend in the form of shares. This strategy will only be implemented once Roth2 has been able to publish stable and strong results, and when the Roth2 share price has developed positively. Tonner Drones will continue to analyze the markets to bring more interesting growth companies to the stock market at an attractive valuation for Tonner Drones as an investor and its shareholders.
