- Supply chain vulnerability: wafer shortfalls in 2021-2022 limited ability to meet demand, drove customer order cancellations
- Competitive risk due to customers shifting inlay procurement mix among suppliers, potentially reducing IC sales volume
- Financial risk from $190M 2025 Notes issued to exchange 2021 Convertible Notes, creating $15M induced conversion expense
