Credo shares fall as MaxLinear targets 20% to 30% of AEC market after $218.1M quarter

MaxLinear, a connectivity chip maker, aims to win 20% to 30% of the active electrical cable (AEC) market in the 1.6-terabit cycle within the next couple of years. Credo Technology Group leads that market, and its shares fell intraday. Chief executive officer Kishore Seendripu put Credo's share at 93% or perhaps 99%, but said the market is diversifying as the technical problem grows more complex. MaxLinear will sell its Annapurna chips to cable makers rather than complete cables, so its AEC revenue will be smaller. It is targeting one or two large US data centres, with first revenue expected in 2027 and a stronger ramp in 2028. Third-quarter revenue rose 72% to $218.1 million. MaxLinear raised its 2026 optical data centre revenue outlook to $250 million to $270 million and guided fourth-quarter revenue to $240 million to $260 million. Foundry supply of its DSP chips remains a constraint.

Credo shares fall 22% in a week, yet one view puts fair value 21% higher at $215

Credo Technology Group Holding (CRDO) used the 2026 OCP Global Summit to showcase its OmniConnect Weaver memory gearbox, which targets bandwidth bottlenecks in programmable logic based AI accelerators. Its shares have fallen about 22% over the past week and roughly 20% over three months. They are still up 18% so far this year, and the three-year total shareholder return exceeds 10x. First-quarter fiscal 2027 revenue rose 114.7% year on year to $479.0 million. Second-quarter guidance of $525 million to $535 million implies a sequential increase of about 9.6% to 11.7%. A narrative-based fair value of $215 per share compares with a last close of $169.70, suggesting the stock is 21% undervalued. However, its price-to-earnings ratio of 59.3x is above the US semiconductor industry's 44.4x and a fair ratio of 50.7x.

Credo over Arm for 2026: revenue up 205.7% to $1.3B, versus Arm's $4.9B and 22.8% growth

Arm and Credo Technology Group are two ways to bet on the AI chip boom, and one analysis favours Credo for 2026. Arm licenses chip architecture used in over 99% of smartphones, while Credo makes high-speed interconnects for AI data centres. In fiscal 2026, Arm's revenue grew about 22.8% to nearly $4.9 billion, with net income of close to $904.0 million. Credo's revenue rose about 205.7% to roughly $1.3 billion, and net income jumped to about $472.3 million from $52.2 million. Credo also looks cheaper, with a forward price-to-earnings ratio of 34.4x against Arm's 119.5x. Its main risk is customer concentration: the top 10 customers account for about 90% of revenue.

Coherent edges Credo as better AI connectivity buy on Zacks Rank, up 42.6% year to date

Credo Technology Group and Coherent both stand to gain from the AI data centre buildout, but Zacks Investment Research rates Coherent the better buy. Coherent carries a Zacks Rank of #2 (Buy), while Credo holds a #3 (Hold). Credo makes high-speed connectivity products, and expects more than 85% year-over-year revenue growth in fiscal 2027. Its risks include customer concentration, with four customers generating roughly 84% of first-quarter revenue, and a cash balance that fell to $764.3 million after the DustPhotonics acquisition. Coherent makes lasers, transceivers and optical materials. It expects first-quarter fiscal 2027 revenue of $2.2 billion to $2.4 billion, though capital expenditure rose to $556 million last quarter. Year to date, Coherent shares are up 42.6% and Credo's are up 24.5%. Credo trades at 23.41 times forward earnings, against 24.73 for Coherent.

Credo pushes past copper limits with 1.6T optical cable.

Credo pushes past copper limits with 1.6T optical cable. ZeroFlap ALC looks to bring copper-class reliability to AI scale-out networks October 14, 2026 Credo unveiled an optical interconnect active light cable (ALC) capable of supporting 1.6-terabit (1.6T) connectivity. The ZeroFlap ALC was unveiled at this week's OCP event in San Jose, California, and is designed for AI scale-out and front-end networks. Credo claims a targeted reach up to 164 feet (50 meters) and a power draw of 12 watts per cable end, with shipping set to start sometime next year. Credo's optical ALC looks to push past copper's distance limits by placing wide-parallel, micro-emitter optics at the end of cables in a pluggable style form factor. These optics use arrays of micron-scale sources - sub-millimeter components that control and transmit light - to process information. Multiple emitters can be used in tandem to push data at optimal individual speeds rather than forcing extreme data rates down just a few optical channels. In practice, the cable splits 200 Gbps (200G) lanes into many low-rate optical channels, which improves flow and reliability. The product boasts a 100 million-hour mean time between failures, while offering improved power and cost overhead compared to traditional pluggable optics. Credo goes as far as to claim it draws roughly 30 percent less power than comparable active electrical cables (AECs) while also being ten times lighter. "For decades, optical transceivers have prioritized data rate per fiber. Our 1.6T ZeroFlap ALCs are engineered with reliability as the first-order concern," L.K. Bhupathi, associate VP of product at Credo, explained. "The scale-up and scale-out links that form the densest connections in AI data centers demand higher reliability than traditional optics were designed to provide. Credo's ALCs bring copper-class reliability to these links, enabling larger GPU clusters and higher-throughput connectivity for massive-scale AI deployments." The ZeroFlap reveal comes as Credo looks to push deeper into optical connectivity. In June, it acquired silicon photonics firm DustPhotonics for around $750 million with its high-speed optical to feed into the ZeroFlap portfolio. In addition to active light cables, Credo is developing optical-based digital signal processors for AI clusters, with a 1.6T offering launching back in March. More in networking.
