- Sluggish demand and delivery dynamics due to excessive inventory levels and lower-than-expected revival of market demand.
- Competition from Chinese semiconductor manufacturers due to government subsidies.
- Climate change risks, including increased costs of greenhouse gas emissions, growing demand and regulations related to sustainability, changes in customer behavior, increasing raw material costs, expenditures associated with transitioning to low-carbon technologies, increased negative feedback from stakeholders, and an increase in extreme weather events.
