Meta CEO Mark Zuckerberg and the company’s board are reportedly clashing over his compensation demands and Meta’s costly artificial intelligence strategy.

Meta posted negative free cash flow of $2.12 billion in the third quarter, its first negative reading since 2012.

Board members have reportedly threatened to resign. Meta’s stock has fallen more than 13% over the past month amid investor concerns about the company’s AI spending.

The dispute challenges Zuckerberg’s strategic direction and financial management of the company.
