Please revise to quantify the approximate percentage of Volta's revenues derived from each of the bullet points on page 251 and revise here and MD&A to clarify: What "behavioral understanding" means and how it relates to advertising revenue; What "customized loyalty solutions for its site hosts and partners" means and whether it is a material part of the Behavior and Commerce or other operations; Where "Charging Network Operations revenue" would fit into the bullet points of different operations; Who determines whether and how much end users pay for electricity at the stations; The approximate percentage of Volta's "Behavior and Commerce" customers that are also customers of Network Development services; The approximate percentage of Network Development revenues derived from utilities and similar entities as compared to retail; and Whether Volta receives a significant amount of Grants and Incentives and other government subsidies, and if so approximately what percentage of Volta's revenues are derived from such sources. Volta is described as owning and operating EV charging stations, but it appears that de minimis revenues are derived from fees paid to Volta by users of the stations. Please revise to clearly explain Volta's business in plain English. Vincent T. Cubbage Tortoise Acquisition Corp. II July 13, 2021 Page 3 Competitive Strengths, page 254 6. Refer to comment 23.
