"When I started Volta, I had a vision for building a company that would support the multi-generational shift to electric mobility," said Scott Mercer, Founder and CEO of Volta. "As I now see a growing slate of iconic vehicles attracting new EV drivers, I have even greater conviction in the mission of Volta. Continuing to build and operate convenient, reliable and accessible public charging is servicing continually increasing public demand, while also aligning with the core business objectives of our partners. As we greet our next chapter as a public company, I am excited about the future, look forward to our next accomplishments, and I am grateful to every employee, investor, client and driver who has supported us over the last eleven years to reach this pivotal point."

Founded on the premise that the electrification of mobility is likely to be a transformational shift, Volta builds and operates a nationwide EV charging network that has among the best utilization per station in the EV charging industry for the United States. Centered around capturing new spending habits expected to result from the shift to electric vehicles, the Company seeks to transform the fueling industry by building open-network charging stations in locations where drivers already spend their time and money, including grocery stores, pharmacies and other retail locations.

"We firmly believe we have invested in the best charging company in the business," said Vince Cubbage, CEO and Chairman of TortoiseCorp II. "Volta is run by an exceptional founder-led team, with the most compelling business model in the industry and an attractive valuation for shareholders. Volta's business model enables the Company to generate revenue from the moment its stations are installed and positions the Company to also capture additional revenue streams as the EV market expands and matures."

Mercer will continue as Chief Executive Officer of Volta, overseeing its vision and evolution, and Chris Wendel will continue as President. Volta's board of directors includes Cubbage, Mercer, and Wendel, as well as the other directors of Volta Industries, Eli Aheto, Martin Lauber, Kathy Savitt, Bonita Stewart and John Tough.
