MaxLinear (MXL) Q4 2025: Infrastructure Revenue Surges 76%, Setting Up Data Center-Led 2026
Infrastructure revenue soared 76% YoY in Q4, propelling MaxLinear into 2026 with a distinct pivot toward high-growth data center and broadband markets. Management’s commentary and segment performance signal a business model increasingly levered to hyperscale connectivity, storage acceleration, and next-gen optical networking. With visibility into multi-year customer ramps and a sharpened strategic focus, MaxLinear is positioned to outpace industry growth, though legacy broadband faces cyclical softness until late 2026 upgrades kick in.
Summary
- Infrastructure Mix Shift: Data center, optical, and storage solutions now drive the majority of growth and future upside.
- Design Win Momentum: Major hyperscale and Tier 1 customer ramps are accelerating content share and visibility.
- Profitability Leverage: Operating and gross margin expansion underpins confidence in sustained cash flow and capital return.
Performance Analysis
MaxLinear delivered a standout Q4, with infrastructure revenue up 76% YoY, now comprising a material portion of total revenue and reflecting the company’s pivot into high-value data center and connectivity solutions. Broadband remained the largest segment at $58 million, but is expected to decline in 2026 as the cable industry pauses ahead of a DOCSIS 4.0 upgrade cycle. Connectivity and industrial multi-market contributed $18 million and $14 million respectively, with connectivity set to benefit from Wi-Fi 7 and Ethernet product ramps.
Gross margins expanded, with non-GAAP gross margin reaching 59.6%, buoyed by favorable infrastructure mix and operational discipline. Operating cash flow was positive at $10.4 million, and inventory metrics improved, reflecting tighter execution. The company repurchased $20 million in stock, underscoring management’s confidence in future growth and cash generation.
- Infrastructure Outperformance: 76% YoY growth in Q4, led by optical DSP and storage accelerator adoption.
- Broadband Soft Patch Ahead: Seasonal and cyclical headwinds expected until DOCSIS 4.0 ramps late 2026.
- Margin Expansion: Product mix and cost control drove sequential and YoY margin improvement.
The quarter marks a clear inflection: infrastructure is set to become the largest revenue driver in 2026, with design win visibility and new product launches providing multi-year growth levers.
Executive Commentary
"In 2026, we expect to achieve a significant and exciting milestone. Our infrastructure category should emerge as the single largest contributor to our overall revenues."

"With strong bookings and improving visibility, we expect to see solid growth in 2026, driven by new design wins and expanding content opportunities across our product portfolio."
Steve Litchfield, Chief Financial Officer and Chief Corporate Strategy Officer
Strategic Positioning
1. Infrastructure-Led Transformation
MaxLinear’s business model is rapidly shifting from legacy broadband toward infrastructure, notably data center optical interconnects, storage accelerators, and wireless infrastructure. The Keystone PAM4 DSP, a digital signal processor for high-speed optical modules, is now ramping at major hyperscalers, with $130 million revenue visibility in 2026 and upside potential into 2027. The forthcoming Rushmore platform, targeting 1.6T optical interconnects, is accelerating customer engagement and expected to enter production revenue late 2026, anchoring the next technology cycle.
2. Multi-Engine Growth Portfolio
Design wins span across Tier 1 OEMs in PON, storage, and rack management, deepening MaxLinear’s content per system and broadening its data center footprint. Storage accelerator SOCs (system-on-chips) are gaining traction with cloud and network appliance providers, with Panther 5 sampling and revenue expected to double in 2026. Wireless infrastructure and industrial multi-market segments are also positioned for steady growth as AI and edge compute architectures proliferate.
3. Margin and Capital Allocation Discipline
Gross margin expansion is being driven by higher-value product mix and operational efficiency, with infrastructure products carrying structurally higher margins. OPEX is set to grow below top-line rates, supporting operating leverage. The $20 million stock buyback in Q4, part of a $75 million authorization, signals management’s conviction in the balance sheet and free cash flow trajectory.
4. Broadband and Connectivity Transition
Broadband faces a cyclical decline in 2026, as cable operators delay spending ahead of DOCSIS 4.0 upgrades, but PON (passive optical network) and Wi-Fi 7 are partially offsetting. Connectivity is expected to grow, with Ethernet and advanced Wi-Fi solutions ramping into commercial and enterprise markets.
Key Considerations
MaxLinear enters 2026 with a fundamentally reshaped business model, leveraging high-value design wins and secular trends in data center and connectivity. Investors should weigh the following:
Key Considerations:
- Infrastructure Mix Inflection: Infrastructure is expected to surpass all other segments as the largest revenue contributor in 2026, fundamentally altering MaxLinear’s revenue base and margin profile.
- Design Win Visibility: Multi-year ramps at hyperscale and Tier 1 customers provide improved revenue visibility and backlog, especially in optical DSP and storage accelerators.
- Broadband Cyclicality: Cable broadband will decline in 2026 due to industry pause ahead of DOCSIS 4.0, with recovery tied to late-year and 2027 upgrade cycles.
- Product Cycle Optionality: New platforms (Rushmore, Panther 5) and derivative products position MaxLinear to participate in emerging opportunities such as LRO/LPO and rack management.
Risks
Key risks center on execution in new product ramps, potential supply chain tightness in optical, and the timing of industry upgrade cycles in broadband. While management expresses confidence in supply continuity and backlog, legacy segments remain exposed to cyclical swings and competitive dynamics, especially as the company pivots toward less predictable, high-growth verticals.
Forward Outlook
For Q1 2026, MaxLinear guided to:
- Revenue of $130 million to $140 million, with infrastructure growth offsetting seasonal declines in broadband and industrial.
- Non-GAAP gross margin of 58% to 61%.
- Non-GAAP operating expenses of $58 million to $64 million.
For full-year 2026, management did not provide formal guidance but highlighted:
- Infrastructure growth outpacing company average, with potential for faster-than-30% segment growth.
- Broadband expected to decline for the year, with recovery dependent on DOCSIS 4.0 timing.
Management emphasized strong visibility into first-half ramps, robust backlog, and improving margin mix, but flagged FX volatility and industry supply constraints as ongoing watchpoints.
Takeaways
MaxLinear’s transformation is accelerating, with infrastructure now the primary growth and margin engine.
- Data Center and Optical Ramp: Keystone and Rushmore platforms are anchoring multi-year hyperscale adoption, driving both revenue growth and strategic relevance in AI and cloud buildouts.
- Broadband Reset: Cable softness will weigh on 2026, but PON and Wi-Fi 7 offer partial offsets and long-term share gains.
- Execution Watchpoints: Investors should monitor product cycle execution, supply chain resilience, and the timing of broadband recovery as key drivers of 2026 performance.
Conclusion
MaxLinear exits 2025 with momentum squarely behind infrastructure, data center, and high-value connectivity platforms. The company’s strategic pivot is translating into both revenue growth and margin expansion, though legacy broadband remains a near-term drag. Execution on new product ramps and continued design win visibility will be critical to sustaining outperformance in 2026 and beyond.
Industry Read-Through
MaxLinear’s results reinforce the sector-wide shift toward data center connectivity, with hyperscale demand for optical DSPs, storage acceleration, and high-speed Ethernet driving secular growth. The company’s commentary on supply chain tightness and customer backlog reflects broader industry dynamics, while the pause in cable broadband spending ahead of DOCSIS 4.0 upgrades is a cautionary signal for peers. Investors should track how content expansion and platform transitions play out across the semiconductor and networking landscape, as similar inflections are likely to reshape segment leaders and laggards in 2026.
