Meta made a deal to keep Mark Zuckerberg from leaving California over its billionaire tax.

It said in a filing that Zuckerberg “was evaluating relocating his primary residence” if California’s Proposition 40 passes. As Bloomberg reports, Meta’s board issued special shares so that he wouldn’t have to leave: > Zuckerberg gets non-voting shares he can sell for liquidity without reducing his voting control. In return, he has committed to remain in California — or wherever Meta is headquartered — for eight years while he remains in a full-time leadership role.
