Prepared Metrics

Q&A Batch (1-

Q&A Batch (6-7 of 7)

Q6 — Sebastian Najee

• Topic: Client market exposure and 2026 outlook
• Key points:
  • Client market contribution is minimal; adoption of CKD/clock chips limited to very high-end client parts.
  • Long-term goal is 20% share in client, but platforms need to ramp; contribution remains minimal even in 2026.
  • Vast majority of business is in data center space.
• Mgmt stance: Neutral – client market is a long-term positioning play, not a near-term driver.

Q7 — Desmond Lynch (with follow-ups from Kevin Cassidy and Aaron Rakers)

• Topic: Silicon IP growth, custom hardware, memory supply constraints, and gross margin guidance
• Key points:
  • Silicon IP business performed in line with expectations in 2025; portfolio focused on high-speed memory interconnect, security IP for AI workloads.
  • Expects IP business to grow in 2026 in line with long-term growth expectations.
  • Custom hardware: supports customers developing their own AI/server chips (accelerators, inference chips); portfolio is laser-focused on PCIe, CXL, HBM, GDDR, security IP.
  • Memory supply constraints: customers report solid server demand (refresh cycle, agentic AI, inference), but are constrained by supply; lead times lengthening; 2026 demand solid but more supply-constrained than demand-constrained.
  • Product gross margin: full-year 2025 was 61.5%, consistent with long-term model of 60%–65%; expects to stay in tight range of 61%–63% in 2026, driven by disciplined pricing and manufacturing cost savings.
• Mgmt stance: Bullish on IP business and gross margin stability; cautious on supply-side constraints limiting 2026 revenue potential.
