https://v-er.eu 3 Subsequent events (post the end of the Quarter) • First strategic drawdown conditions were met on the Company’s €2.2bn ($3.9bn) Lionheart funding package with initial equity funds received by the Company from its strategic equity partners • Civil construction activities commenced at the Lionheart 30MW geothermal power plant site in Landau. Civil construction activities include preparation and construction of key foundations and concrete works for the power plant buildings and equipment, and building out road infrastructure. Vulcan’s Managing Director and CEO, Cris Moreno, commented: “Vulcan continues to deliver against the planned execution program for our flagship Lionheart Project. “Importantly, the lithium demand outlook remains strong, while Vulcan has robust downside price protection via its Lionheart offtake agreements . The global need for domestic energy security and critical materials sovereignty is driving demand. This is particularly evident in Europe where growth is being underpinned by key European producers and Asian companies entering the market through partnerships to localise supply chains per European requirements. “This momentum is positive for Vulcan, as we are well positioned with our foundation Lionheart Project, along with our future phase growth pipeline, to deliver long-term, local, and low-cost energy and lithium to Europe. “Following a strong first half of the year , we remain focused on delivering Lionheart on time , on budget, and without incident.”
