Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	HVII is a SPAC with no business operations. Since its initial public offering, its sole business activity has been identifying and evaluating suitable acquisition transaction candidates. Therefore, HVII does not consider that it faces significant cybersecurity risk and has not adopted any cybersecurity risk management program or formal processes for assessing cybersecurity risk. HVII depends on digital technologies, including information systems, infrastructure and cloud applications and services, including those of third parties with which it may deal. Sophisticated and deliberate attacks on, or security breaches in, its information systems or infrastructure, or the information systems or infrastructure of third parties or the cloud, could lead to corruption or misappropriation of its assets, proprietary information and sensitive or confidential data. Because of its reliance on the technologies of third parties, HVII also depends upon the personnel and the processes of third parties to protect against cybersecurity threats. In the event of a cybersecurity incident impacting HVII, the management team will report to the board of directors and provide updates on the management team’s incident response plan for addressing and mitigating any risks associated with the cybersecurity incident. As an early-stage company without significant investments in data security protection, there can be no assurance that HVII will have sufficient resources to adequately protect against, or to investigate and remediate any vulnerability to, cyber incidents. It is possible that any of these occurrences, or a combination of them, could have adverse consequences on its business and lead to financial loss. As of the date of this Report, HVII has not identified any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that it believes have, or are likely to, materially affect it since its initial public offering.
