The Company immediately activated its cyber incident response process to contain the intrusion, assess and investigate the incident and implement remedial measures. The Company also immediately notified law enforcement and retained external cybersecurity experts to assist.

Based on the information reviewed to date, the Company believes the unauthorized activity has been contained and is working diligently to bring the impacted portions of its IT systems and individual computer devices back online. Although the Company ascertained that certain information was exfiltrated, it is still investigating the extent of compromise of any sensitive information contained within the accessed IT systems. However, it is believed that the threat actors unlawfully accessed certain computer systems and exfiltrated images of video meetings and computer screens that may contain sensitive Company information. The threat actors have threatened to release this information publicly i
