HyImpulse: German space company successfully launches firstcommercially viable launch vehicle•

HyImpulse introduces a new propulsion concept utilizing paraffin (candle wax) andoxygen as fuel.

•New launch vehicle technology offers 50 percent cost reduction compared toconventional kerosene-based launch vehicles. Designed for commercial utilization,
HyImpulse’s launch vehicles enable cost-effective transport of small satellites intospace. Order books exceeding 100 million euros signal strong market confidence.

•The successful launch marks a significant step towards Europe’s access to space.

•The initial launch of an orbital launch vehicle with increased payload capacity isscheduled for the end of 2025.

Heilbronn (Germany)/Koonibba (Australia), May 3, 2024 - For the first time, a German company
has achieved the "lift-off" of a commercially viable launch vehicle. At the Australian launch site in
Koonibba, HyImpulse, a German manufacturer and system provider of commercial launchvehicles for satellite transport, successfully test-launched the 12-metre-long and 2.5-tonne
single-stage rocket "SR75", which can transport small satellites weighing up to 250 kg to an
altitude of around 250 km. At 14:40 PM ACST or 7:10 AM CET, the launch vehicle lifted off
successfully and the hybrid rocket propulsion system of the launch vehicle operated as planned.
After the successful lift-off, the SR75 will be retrieved for further examination and analysis of thedata.

HyImpulse introduces a groundbreaking propulsion concept with its rockets, utilizing solid
paraffin (commonly known as candle wax) and liquid oxygen as fuel. Paraffin, being both costeffective and inherently safe as a fuel, serves as an alternative to conventional liquid or solid fuelsand does not have the risk to explode. This innovative design significantly simplifies theconstruction of launch vehicles, cutting costs by a remarkable 40 percent compared to
traditional propulsion systems. As a result, satellite transportation expenses are reduced by animpressive 50 percent, demonstrating HyImpulse's commitment to affordable access to space.
Dr. Mario Kobald, co-founder and co-CEO of HyImpulse: " Setting up a commercial launchvehicle equipped with entirely new propulsion technology up for launch and lift-off with such anefficient team and a relatively small budget is quite a feat. We're signaling Germany's prowess asa spacefaring nation and expanding Europe's access to space. Already, we're planning the launchof a larger, multi-stage transport launch vehicle capable of deploying satellites weighing up to 600
kilograms into low Earth orbits by the end of next year."Dr. Christian Schmierer, co-founder and co-CEO of HyImpulse: "With this successful launch,which also provides us with valuable data for further development, we have validated ourtechnical concept and demonstrated our market readiness. Our utilization concept is designed
for the cost-effective transport of small satellites into space. This enables the implementation ofHyImpulse Technologies GmbH

100 million Euro, our order book is already substantial and continues to grow monthly."
The SL1 multi-stage orbital launch vehicle, scheduled for its inaugural lift-off by the end of 2025,
stands at a height of 32 meters and weighs 50 tons. Depending on the weight of the payload, it
can ascend to an altitude exceeding 500 km, i.e. reaching low Earth orbits. Designed for costeffective transportation of small satellites into space, it can carry payloads of up to 600 kilograms
to low Earth orbits.
