Quick Summary

Meta revealed in a recent SEC filing that CEO Mark Zuckerberg threatened to sell his $110 million home in Palo Alto and move out of California if Proposition 40, which would impose a 5% wealth tax on billionaires, passes. This could force him to liquidate stock worth approximately $250 billion, potentially reducing his voting interest in Meta to around 53%. Talks between Zuckerberg and the board about this issue began in July and involved discussions over how to revise his compensation agreement to provide better liquidity in case of such a large tax bill.

Story summary

Mark Zuckerberg, CEO of Meta Platforms, made a deal with the company's board to help him avoid losing control over Meta if voters approve California Proposition 40, a proposed one-time 5% wealth tax on billionaires. The proposition could impose a $12 billion tax bill on Zuckerberg, who has a net worth of approximately $220 billion according to Forbes. In response, Meta created a new class of non-voting stock that allows Zuckerberg to sell shares without diluting his voting control. This deal commits him to remain in California for eight years unless he faces unforeseen circumstances, effectively addressing his threat to leave the state and potentially liquidate his assets if Prop 40 passes on November 3.
