Negatives

Key Dates

Recommendation

The company demonstrates strong revenue growth and platform adoption, but rising component costs are pressuring gross margins, and there are indications of shipment delays. While the long-term AI strategy is promising, the near-term margin headwinds and operational adjustments warrant a cautious 'hold' stance until these pressures stabilize.
