Prepared Metrics

Q&A Batch (1-5 of 5)

Q1 — Tore Svanberg

• Topic: 2026 growth outlook vs 2025 30% YoY growth
• Key points:
  • 2025 tracking to ~30% YoY growth; Street estimates for 2026 are ~20% (≈2x industry expectation).
  • Growth drivers: infrastructure (optical customer wins, wireless infrastructure acceleration, storage accelerator); broadband expected to moderate.
  • Infrastructure revenue target: $300M–$500M over next 2–3 years.
• Mgmt stance: Cautiously bullish — optimistic based on design-win breadth and booking strength, but conservative due to customer concentration and complex system ramps.

Q2 — David Williams

• Topic: Optical revenue trajectory and gross margin guidance
• Key points:
  • Optical revenue in 2025 largely from 400Gb solutions; 800Gb beginning to ramp late 2025 into 2026.
  • Gross margin guidance implies ~64%–65% incremental margin (30bp improvement); infrastructure mix supports higher margins.
  • Fab lead times increased and fabs raising prices, consuming margin gains.
• Mgmt stance: Neutral on margins — progress but not as much as hoped due to fab cost pressures; bullish on optical growth potential.

Q3 — Joseph Quatrochi

• Topic: Data center optical pipeline and broadband seasonality
• Key points:
  • Interops with major data centers passed; generating own momentum and design-win pull.
  • Optical and wireless infrastructure growth expected to be of "same order" in 2026.
  • Broadband grew 80% YoY; expects moderation; PON poised for strong growth with a major North American telecom operator.
  • DOCSIS upgrade (late 2026–2027) and telco CapEx over next 2 years support broadband outlook.
• Mgmt stance: Bullish on infrastructure (optical/wireless); cautious on broadband near-term moderation but positive on multi-year CapEx cycle.

Q4 — Timothy Savageaux

• Topic: Accelerating growth commentary and Q4 infrastructure breakdown
• Key points:
  • "Accelerating growth" refers to new opportunities (data center, wireless, storage accelerators) growing well above company's ~20% Street estimate.
  • Optical mid-range implies 80%–90% growth; accelerating could approach triple-digits.
  • Q4 infrastructure is biggest contributor to sequential growth; broadband moderation is modest; industrial multi-market improving.
• Mgmt stance: Bullish — data center leads growth; infrastructure growth back-end loaded with strong 2026 revenue outlook.

Q5 — Christopher Rolland

• Topic: Optical hyper-growth vs solid growth; broadband DOCSIS vs fiber
• Key points:
  • Growth assumptions based on already-ramping wins; hyper-growth would require more share than planned.
  • Key risks: laser/silicon availability, timing of wins translating to revenue.
  • DOCSIS 4.0 ramp delayed by main players due to network upgrade complexity; fiber growth driven by North American operator ramp and new share wins.
• Mgmt stance: Cautious on hyper-growth — solid growth based on current ramps; neutral on broadband — DOCSIS delay offsets fiber opportunity, but fiber ramp is meaningful.

Q&A Batch (6-10 of 10)

Q6 — Ananda Baruah

• Topic: Growth trajectory differences vs. COVID era; neocloud relationship strategy
• Key points:
  • Current growth is infrastructure-driven (vs. broadband-driven in COVID); new revenues have huge TAMs with tiny market share.
  • Inventory is in equilibrium (no excess stocking); supply chain is tighter with geopolitical issues and foundry pricing power.
  • Advanced nodes (16nm and beyond, FinFET) are entrenched; fabs have muscled pricing power, requiring innovation to maintain margins.
• Mgmt stance: Bullish on long-term growth due to new infrastructure TAMs, but cautious on margin pressure from supply chain and foundry costs.

Q7 — Quinn Bolton

• Topic: Broadband growth moderation (Q4 guidance); Keystone DSP supply advantage at Samsung
• Key points:
  • Broadband growth is moderating in absolute terms, not declining; Q4 guidance reflects this, with no full-year 2026 guidance given.
  • PON is picking up (market share gains); DOCSIS 4 ramp expected in late 2026/2027 with 50% content increase.
  • Keystone (5nm CMOS, Samsung) is the only 100G/lane product in production; Rushmore (1.6T, 200G/lane) also at Samsung, providing diversification.
• Mgmt stance: Neutral on broadband near-term (moderation), bullish on long-term content gains; cautious on supply constraints limiting hyperbolic growth.

Q8 — Richard Shannon

• Topic: Rushmore DSP incumbency; industrial multi-market outlook
• Key points:
  • Rushmore (200G/lane) demoed at OFC; competitor announced earlier, but MXL believes product is more differentiated; production in 2026, but no revenue baked in for 2026; realistic timeline is 2027.
  • Keystone is driving current DSP revenues.
  • Industrial multi-market declined due to geopolitics and license expiry; deliberate pricing discipline maintained gross margins; investments focused on edge/cloud data center.
• Mgmt stance: Neutral on Rushmore near-term (no revenue until 2026/2027); cautious on industrial recovery, but investing sustainably.

Q9 — Steven Litchfield (answering Karl Ackerman)

• Topic: PON content opportunity; optical DSP design engagements (800G vs. 400G crossover)
• Key points:
  • PON gateway content can be $40–$50 (WiFi, Ethernet, SoC); unit growth and share gains expected over next 2 years.
  • Engaged with all major module makers in Asia and America; 800G deployments vary by hyperscaler (e.g., Google past 800G, NVIDIA not engaged).
  • No specific timeline given for 800G revenue crossing 400G revenue.
• Mgmt stance: Bullish on PON content growth; neutral on 800G crossover timing (depends on customer cadence).

Q10 — Sujeeva De Silva

• Topic: DOCSIS 4 adoption delays; arbitration update; OpEx trajectory
• Key points:
  • DOCSIS 4 delays due to network upgrade complexity (nodes, amplifiers); most deployments will be Ultra DOCSIS 3.1, not 4.0; 4.0 is a North American phenomenon.
  • Arbitration is on track to commence this quarter, with resolution expected in H1 2026; management feels positive.
  • OpEx slightly higher due to software/platform support for large customers; operating margins expected to develop through 2026 as revenue ramps.
• Mgmt stance: Neutral on DOCSIS 4 (slow deployment); bullish on arbitration outcome; bullish on operating leverage in 2026.
