A limited number of customers account for a large portion of revenue; two end customers each represented over 10% in recent years, with one contributing 26% in 2025. Changes in their capital expenditure priorities, AI investment shifts, or cost optimization efforts could materially reduce revenue and increase demand forecasting uncertainty.
