Investor Verification Checklist
- Verify the final net proceeds received and the specific allocation of funds beyond general corporate purposes.
- Review the terms of the capped call transactions (Exhibit 10.1) to understand the exact dilution protection mechanics and cap price adjustments.
- Monitor the Company's stock price relative to the conversion price ($36.99) and the cap price ($47.0750) to assess conversion likelihood and dilution risk.
- Confirm the Company's liquidity position post-transaction to ensure compliance with covenants and ability to meet future obligations.
- Check for any subsequent filings regarding the registration of shares issuable upon conversion, as the Notes and shares are currently unregistered.
