The rapid expansion of AI cluster scale is driving a fundamental shift in underlying network architecture, moving from a focus on "pursuing bandwidth" to prioritizing "reliability and power efficiency."
Credo Technology Group Holding Ltd, a leader in optical interconnectivity, has once again demonstrated the explosive potential of the optical and copper interconnect market within AI infrastructure, reporting annual revenue that more than tripled.
During an earnings call, management asserted that an even more powerful wave of growth may have just begun.
Credo Technology Group Holding Ltd delivered a stunning performance for its 2026 fiscal year, reporting full-year revenue exceeding $1.3 billion, a staggering 206% year-over-year increase.
Non-GAAP net profit surged more than fivefold to $662 million.
Fourth-quarter revenue alone reached a record $437 million, not only setting a new high but surpassing the company's total revenue for the entire prior fiscal year.
The quarterly net profit of $227 million was even 33% higher than the total revenue from the same period last year.
CEO Bill Brennan characterized this as a concentrated display of "super leverage" effect during the call.
Brennan pointedly noted that as AI clusters scale from tens of thousands to hundreds of thousands of GPUs, the core bottleneck constraining system performance is no longer computational power itself, but rather the reliability and efficiency of the networks connecting these systems.
"Even isolated link instability can severely drag down GPU utilization and cluster deployment timelines," he stated.
This assessment directly underpins Credo's strategic value as a core supplier of AI interconnect infrastructure.
Looking ahead, management forecasts total revenue growth exceeding 80% for fiscal year 2027, with the largest variable coming from its optical business.
Three product lines—Optical DSPs, Silicon Photonics (SiPho PICs), and Zero-Flat Optics (ZF Optics)—are each expected to contribute over $100 million in revenue, totaling more than $600 million.
Simultaneously, revenue from emerging cloud customers (NeoCloud) is anticipated to reach approximately 20% of the total, while the Weaver gearbox chip is viewed as the next major growth driver for fiscal year 2028.
**Financial Surge: "Super Leverage" in Profits, Single Quarter Outpaces Prior Full Year**
Amid the high-speed expansion wave of AI infrastructure, Credo's financials demonstrated powerful economies of scale.
Full-year FY2026 revenue surpassed $1.3 billion, up approximately 206% year-over-year, while non-GAAP net profit skyrocketed over five times to $662 million.
"FY2026 was another defining year for Credo," CEO Bill Brennan stated bluntly at the start of the call, adding that few semiconductor companies can achieve such rapid scaling while maintaining product leadership, strong margins, and excellent operational execution.
The explosive force of the fourth quarter was particularly notable, with revenue hitting a record $437 million, a 157% year-over-year increase.
Brennan emphasized a striking data point: "It's worth noting that our single-quarter revenue in Q4 even exceeded our total annual revenue for FY2025."
CFO Dan Fleming highlighted the margin leverage: "In Q4, our non-GAAP net profit reached a record $226.7 million... This figure is 33% higher than our total revenue from the same quarter last year. This most clearly demonstrates the magnitude of our top-line growth, strong gross margins, and discipline in managing operating expenses."
**Market Focus Shifts: From "Compute Anxiety" to "Interconnect Anxiety," Network Reliability Takes the Throne**
A core market concern is whether the astonishingly high growth of AI connectivity chips is sustainable.
Credo's answer points to a shift in the underlying logic.
"As AI clusters expand from tens of thousands to hundreds of thousands of GPUs, connectivity is no longer just about bandwidth," Brennan pinpointed the current data center pain point.
"Today's AI infrastructure is increasingly constrained; the bottleneck is no longer compute power but the reliability and efficiency of the networks tying these systems together."
He explained customer anxiety in relatable terms: "In an environment where cluster downtime can cost millions and delay AI deployment schedules, network reliability is more important than ever. Even isolated link instability can seriously impact cluster bring-up time, GPU utilization, and overall system availability. That's why network reliability has been Credo's 'North Star' for the past several years."
**Finding Future Growth: The "Optical Inflection Point" in FY2027, Three Pipelines Target $600M**
While copper cable (AEC) business remains the company's core growth engine, market focus is firmly on its impending optical business boom.
Credo anticipates total revenue growth exceeding 80% year-over-year for FY2027, with the largest variable being optical products.
"We believe FY2027 will be an inflection point for Credo's optical business," Brennan stated, providing a market-shaking outlook.
"In FY2027, we expect Optical DSPs, Silicon Photonics PICs, and Zero-Flat Optics each to contribute over $100 million in revenue, totaling over $600 million, with this growth expected to accelerate in the second half."
Pressed by analysts on the specific value of these three lines, Brennan revealed valuable pricing details: "For discrete components like Optical DSPs and Silicon Photonics PICs, the ASP is typically in the double digits. But for ZF Optics, we will see triple-digit ASPs. So, clearly, as we ramp ZF Optics production, it will become the largest revenue contributor within our optical portfolio."
Following the recent acquisition of DustPhotonics, which secured silicon photonics (SiPho) PIC technology, Brennan praised its architecture for "significantly simplifying optical design and drastically reducing laser counts... the reduction in laser count can even alleviate supply chain constraints across the industry."
**Customer Base Reshuffles: Moving Beyond "Giant Dependence," NeoCloud Could Capture 20% Share**
Regarding order concentration, the market has been concerned about over-reliance on a few North American tech giants in the AI supply chain.
Credo showcased its increasingly decentralized customer structure.
CFO Fleming provided the latest data: "In Q4, we had four customers each representing over 10% of revenue, at 34%, 27%, 16%, and 10% respectively. Notably, the fourth customer had not previously reached the 10% threshold in FY2026."
Beyond top-tier hyperscalers, Brennan expressed great enthusiasm for the emerging customer segment: "This is one of the most encouraging major trends—the rise of the NeoCloud ecosystem. They are building AI infrastructure platforms to support a wide range of applications, from model developers to enterprises to sovereign AI."
He added, "They might be the perfect customer for Credo because they move extremely fast, deploy highly optimized architectures, and place extreme importance on network performance, reliability, and deployment speed. If we look at this group of NeoCloud customers collectively, I absolutely believe their share could reach around 20%."
**Long-Term Vision: New Frontiers for FY2028 and the Ultimate Supply Chain Test**
For future growth engines, management looked further ahead to FY2028, highlighting Active LED Cable (ALC) and the Weaver gearbox chip, which addresses memory bandwidth challenges.
When asked about the commercial potential of these new products, Brennan provided an exciting estimate: "Taking our first Weaver customer as an example, they are deploying up to 2TB of memory... This will require a very large number of Weaver chips. I've said before that the revenue contribution per GPU could be between $2,000 and $3,000. So, you can see that as customers go into production, this product category will also ramp very quickly."
Behind this optimistic outlook, however, lies the industry-wide supply chain challenge.
"Overall, I think supply chain tightness is likely to persist into next year and perhaps beyond," Brennan acknowledged to the market, but then asserted strong confidence: "We have extremely close relationships with our supply chain partners. I think there's a strong consensus in the industry—clusters don't get built without the small complementary connectivity chips that we build and embed into system-level products."
Concluding the call, Brennan summarized: "FY2026 was another transformative year for Credo. But we firmly believe that in facing the enormous opportunity ahead, we are still in the early innings."
