Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Risk Management and Strategy Our cybersecurity program is designed to identify, detect, protect against, respond to, and recover from cyber risks and incidents. Our cybersecurity program is part of our internal risk management processes, and we continually improve our cybersecurity practices as new threats and vulnerabilities emerge. Our Chief Information Officer (“CIO”), Chief Information Security Officer (“CISO”), and Vice President of Cybersecurity, all within our “CIO organization,” lead our Detection and Response Team (“DART”) which is responsible for our cybersecurity incident response processes pursuant to our Incident Response Plan and playbooks. The DART also includes members of our IT department responsible for supporting the technologies and processes to protect against, detect, contain, mitigate, and recover from cybersecurity incidents. The DART evaluates and assigns severity levels to cybersecurity incidents and, based on the severity, escalates and engages incident response teams to respond to and mitigate the risks. Our cybersecurity team proactively hunts for cyber threats and vulnerabilities in our networks and information systems as part of our cyber risk management program. This includes monitoring our networks and systems for indicators of compromise (“IOCs”), active intrusion attempts, and other suspicious activity, including insider threat risks. The cybersecurity team stays apprised of existing and emerging cybersecurity threats through commercial threat intelligence feeds and by partnering and data sharing with third parties such as the U.S. government, law enforcement agencies, customers, and other Defense Industrial Base (“DIB”) participants. We also engage third parties to conduct evaluations of our cybersecurity controls by performing penetration testing and controlled cybersecurity framework audits. We also review the cybersecurity practices of our third-party service providers and suppliers. We require our employees to take cybersecurity-related training regularly to promote awareness of how to detect, report, and respond to cybersecurity threats. Employees with certain roles and responsibilities are also assigned cyber training for their specific functions. We also maintain an Insider Threat program, headed by our Director of Security, to identify, assess, and deal with potential risks from within our company, including cybersecurity risks. We have aligned our cybersecurity program to the National Institute of Standards and Technology’s (“NIST”) published cybersecurity standards, and our policies and processes are compliant with NIST Special Publication 800-171 and other applicable publications. Given our status as a defense contractor, we are subject to numerous regulations, including those pursuant to the Defense Federal Acquisition Regulation Supplement (“DFARS”), requiring us to have controls in place to protect U.S. government CUI and to report cybersecurity incidents to the DoD. We are also subject to the DoD CMMC requirements which necessitates that companies receiving, storing, or processing federal contract information (“FCI”) and CUI be formally assessed by a CMMC C3PAO. AeroVironment, Inc., including its subsidiaries Arcturus UAS and Tomahawk Robotics (but excluding any of the BlueHalo acquired entities) is scheduled for a formal Level 2 assessment. The recently acquired BlueHalo passed a formal CMMC Level 2 assessment under the CMMC 2.0 framework, which went into effect December 16, 2024. If we fail to achieve or maintain certification ahead of contract awards, or if we fail to achieve the level required for a particular contract, we will be unable to bid on new contracts or follow-on efforts containing CMMC clauses, which could adversely impact the success of our operations. Additionally, our subcontractors and certain vendors may need to obtain CMMC certification, and we may be negatively impacted if they are not compliant with the CMMC requirements.
