Key Takeaways
  • • Mark Zuckerberg owns about 13% of Meta's economic value but holds roughly 61% of its voting power through Class B shares carrying 10 votes each, according to a Meta SEC filing released Wednesday.
  • • California's Proposition 40 would impose a one-time 5% tax on billionaires' net worth, and a wealth tax would be assessed on Zuckerberg's ownership stake, potentially forcing share sales that would erode his voting control.
  • • Meta's independent special committee negotiated a dividend of nonvoting Class C shares, one for each share held, allowing Zuckerberg to sell 20% of his new shares (10% of his economic stake) to pay a potential tax without affecting his majority control.
  • • Zuckerberg committed to remain in California, or wherever Meta is headquartered, for eight years, absent material unforeseen circumstances.
  • • Meta CFO Susan Li said the nonvoting class will fund growth, AI spending, acquisitions and employee compensation, with the filing stating the company may need to raise hundreds of billions of dollars beginning as early as fall 2026.
Summary
A Meta SEC filing released Wednesday shows that Mark Zuckerberg's economic ownership and voting control diverge sharply. He holds about 13% of the company's value but about 61% of its votes, because his mostly Class B shares carry ten votes each while Class A shares carry one. According to the filing, that majority lets him elect the full board and decide nearly every shareholder vote.

The disclosure comes as California voters prepare to decide on November 3 whether billionaires should pay a one-time 5% tax on net worth under Proposition 40. A wealth tax would be assessed on the roughly 13% economic stake, and paying it would require selling shares. Each sale of Class B stock converts those shares into one-vote Class A shares, so any sale to fund the tax would reduce Zuckerberg's voting control. The filing states he "could become liable for a significant, multibillion-dollar tax payment," and the independent committee said the tax "has the most significant impact because it would require him to sell shares, or at least borrow against them."

To address this, the special committee proposed in August a dividend of new nonvoting stock payable only if Proposition 40 became law and a tax became due. Zuckerberg pushed for a broader solution, arguing that the ratio of voting control to economic interest should not be preserved and citing other companies where founders held control with small economic stakes. The final deal, reported by Fortune, gives every shareholder one nonvoting Class C share for each share held. Zuckerberg may immediately sell 20% of his new shares, representing 10% of his overall economic stake, for any reason, including paying a potential Proposition 40 tax, without affecting his majority voting control. The committee noted that because he takes a $1 salary, the tax would otherwise leave him effectively paying to serve as CEO while living in California.

The board also sought to keep Zuckerberg in California. The committee said it was crucial he remain close to management and to Meta Superintelligence Labs. The final agreement commits him to remain in California, or wherever Meta is headquartered, for eight years, absent material unforeseen circumstances. Zuckerberg had told the committee on September 6 that he would need to begin steps by mid-September to establish residency outside California by mid-October.

Meta told Fortune the new shares are mainly meant to finance AI spending. CFO Susan Li said on the earnings call that the class would create a publicly traded nonvoting stock usable for capital raising, employee compensation and acquisitions while preserving voting power of existing shareholders. The filing says management forecasts showed a need to raise hundreds of billions of dollars over several years beginning as early as fall 2026, and it acknowledges the new stock "could substantially prolong the duration of Mr. Zuckerberg's voting control." Class A shareholders did not vote on the change, because Zuckerberg has the ability to unilaterally approve it.
