  1. With your recent disclosure of a customer exceeding 10% of revenue, can you clarify whether this customer concentration is expected to continue, and what risks it might pose to your business strategy?
  2. Given that the Street is projecting your Enterprise Data segment to reach nearly $1.1 billion in revenue next year, do you believe this expectation is reasonable amidst the competitive pressures and potential pricing challenges you've mentioned?
  3. Considering that internal inventory days have decreased significantly while channel inventory remains lean, is there a risk that some of your recent growth is driven by inventory fill, and how are you managing inventory levels to prevent future shortages or overages?
  4. With increasing competition in the AI power market, including aggressive pricing strategies from Chinese suppliers, are you experiencing any pricing pressure, and what measures are you taking to sustain your market position and margins?
  5. Although you've invested in expanding your data converters product line, revenue from this segment remains small; what challenges are you facing in gaining market share, and how do you plan to accelerate growth in this area?
