5. What happens next?

6. What should investors know?

• Check Your Tickers: Ensure your brokerage platform is using the correct symbols: FAC for common stock and FACWW for warrants.
• Expect Volatility: It is common for stocks following a SPAC merger to experience significant price swings as the market finds a fair valuation.
• Follow the Cash: When reviewing quarterly reports, pay close attention to capital expenditures. You want to see that the company is effectively deploying its cash toward building production capacity rather than just covering day-to-day overhead. The ultimate test is whether they can manufacture battery cells at scale while keeping costs competitive.
