Meta warns investors – because of Mark Zuckerberg's tangible hobbies. Zuckerberg and several other managers participated in "high-risk activities such as martial arts, extreme sports and recreational flying" That could "lead to serious injury and death," Meta noted in the detailed report for last year published over the weekend.

It is the first time that the Facebook Group has included such a reference to its boss's hobbies in its usual risk warnings for investors. As before, Meta emphasized that if Zuckerberg were no longer available for whatever reason, this would have “significant negative consequences” for the business.
