Performance Analysis

Credo delivered a breakout quarter, with Q4 revenue up 180% year over year and 26% sequentially, reaching $170 million and capping a fiscal year of 126% top-line growth. The product business, led by Active Electrical Cables (AEC), posted 276% YoY growth, while non-GAAP gross margin hit 67.4%, up 355 basis points sequentially and well above the company’s long-term model. Operating leverage was substantial, as operating expenses rose only 19% sequentially against a 26% revenue jump, driving non-GAAP operating margin to 36.8% and net margin to 38.4%—both well ahead of management’s prior targets.

Cash generation was equally robust, with free cash flow of $54.2 million and cash increasing by $52.1 million quarter over quarter. The customer mix remains concentrated—one customer represented 61% of Q4 revenue, with two others at 12% and 11%—but management expects diversification as two new hyperscalers ramp through fiscal 2026. Inventory rose to $90 million as Credo prepares for continued high-volume shipments. Product mix and scale drove margin expansion, though management guided for near-term gross margin normalization to the 65% range, citing typical mix fluctuations rather than structural pressure.

• Customer Concentration Persists: Top three customers accounted for 84% of Q4 revenue, but two new hyperscalers are set to diversify the base in fiscal 2026.
• AEC Momentum Remains Relentless: Double-digit sequential growth continues, with scale-out AI deployments driving the majority of shipments.
• Optical and Retimer Businesses Gain Traction: 100G and 200G optical DSPs and PCIe Gen 6 retimers are building pipeline and design win momentum for future periods.

The company’s ability to scale operations and execute on customer ramps is translating into both top-line acceleration and margin leverage, validating the system-level approach and diversified product roadmap.

Executive Commentary

Strategic Positioning

1. Hyperscaler Penetration and Customer Diversification

Credo’s core growth engine remains hyperscaler adoption, with three customers each contributing over 10% of revenue in Q4 and two additional hyperscalers expected to ramp in the second half of fiscal 2026. This move from concentrated to more distributed revenue sources is critical for risk mitigation and long-term durability, especially as AI infrastructure investments accelerate globally.

2. System-Level Innovation and Full-Stack Ownership

Credo’s differentiated approach—owning the entire solution stack from advanced IP to system-level design— has enabled rapid product iteration and time-to-market advantages. The PILOT software platform, integrating predictive integrity and telemetry, extends this edge by providing customers with robust debugging and monitoring tools, reinforcing stickiness and value beyond hardware alone.

3. Product Leadership in AEC, Optical, and Retimers

The company’s AEC products are now the de facto standard for inter-rack copper connectivity, offering reliability and energy efficiency advantages over both DAC and optical alternatives. Optical DSPs, especially at 100G and 200G per lane, are gaining momentum, with industry-first power efficiency benchmarks and strong customer interest. Retimer solutions for PCIe Gen 6 are positioned for design wins and production ramps in calendar 2026, broadening Credo’s addressable market as data center architectures evolve.

4. Operational Agility and Supply Chain Readiness

Credo’s dual operations teams—one for silicon, one for system assembly—have enabled rapid scaling without major bottlenecks, supported by close relationships with cable assembly partners. The company’s flexible geographic approach to manufacturing provides a buffer against tariff and geopolitical risks, with the ability to shift production locations within months if necessary.

5. Capital Allocation and Margin Expansion

Operating leverage is a key theme, as opex growth is running at less than half the pace of revenue expansion. CapEx is set to double in fiscal 2026, driven by advanced tapeouts at leading process nodes (three nanometer), but management is clear that these investments are foundational for long-term product leadership rather than tied to specific customer commitments.

Key Considerations

This quarter’s results highlight both the opportunity and complexity of scaling with hyperscaler customers in a rapidly evolving AI data center market. Investors should weigh the following:

Key Considerations:

• Customer Mix Volatility: While diversification is underway, a single customer still accounted for 61% of Q4 revenue, making near-term results sensitive to individual ramp profiles.
• Product Mix and Margin Dynamics: Gross margin is elevated but will fluctuate as new products and customers ramp, with management guiding to a 65% midpoint for Q1 2026.
• Tariff and Geopolitical Exposure: Manufacturing flexibility is a mitigant, but evolving US-China tariffs and supply chain shifts could impact cost structure and lead times.
• Optical and PCIe Roadmap Execution: Success in 100G/200G optical DSPs and PCIe Gen 6 retimers will be critical for sustaining growth as copper AEC adoption matures.
• Capital Intensity and R&D Allocation: Doubling CapEx for advanced node tapeouts reflects a long-term bet on product leadership, but requires continued execution to translate into revenue and margin expansion.

Risks

Customer concentration remains a structural risk, with any delay or shift in hyperscaler spend likely to impact results disproportionately. Tariff policy uncertainty and supply chain realignment could introduce cost or operational volatility, despite Credo’s efforts to diversify manufacturing locations. Product mix changes and competitive dynamics, especially in optical and system-level solutions, may pressure margins or require incremental investment to maintain leadership.

Forward Outlook

For Q1 fiscal 2026, Credo guided to:

• Revenue between $185 million and $195 million, up 12% sequentially at the midpoint
• Non-GAAP gross margin of 64% to 66%
• Non-GAAP operating expenses between $54 million and $56 million

For full-year 2026, management expects:

• Revenue to exceed $800 million (over 85% YoY growth)
• Non-GAAP net margin approaching 40%
• Operating expenses to grow at less than half the rate of revenue

Management highlighted:

• Continued hyperscaler customer ramps and two new hyperscalers onboarding in the second half
• Ongoing product innovation in AEC, optical, and PCIe as key growth drivers

Takeaways

Credo’s Q4 results and fiscal 2026 guidance underscore a business at the center of the AI data center build-out, with system-level innovation, customer diversification, and margin leverage all moving in the right direction.

• Hyperscaler Ramps Remain the Top Catalyst: Execution on onboarding two additional hyperscalers will be the biggest determinant of revenue stability and upside in fiscal 2026.
• Optical and PCIe Offer Next Leg of Growth: Design wins and production ramps in optical DSPs and PCIe retimers will diversify revenue streams and support long-term growth.
• Margin Expansion Is Not Linear: Gross and net margins are well above historical levels, but investors should expect quarter-to-quarter variability as product and customer mix evolves.
