Meta Platforms faces Santa Clara County civil lawsuit over advertising model as stock trades at US$603.00, down 4.3% over the past month

Santa Clara County filed a civil lawsuit against Meta Platforms targeting the company's core advertising model, putting AI-driven monetization and regulatory risk under legal scrutiny.

Meta's stock price stands at US$603.00 with a current P/E ratio of 21.7x, compared to the US Interactive Media and Services industry at 15.2x and peers at 29.1x; the most followed fair value estimate places the stock at US$723.11, suggesting 16.6% undervaluation.

The company's 3-year total shareholder return of about 1.5x reflects earlier AI optimism now meeting heavier scrutiny from lawsuits, regulatory probes, and fresh bond issuance, raising questions about future compliance costs and Reality Labs' ongoing losses.
