Nvidia Kyber NVL144 rack delivery pushed into 2028 as manufacturing issue hits key circuit board, SemiAnalysis says

Nvidia’s Kyber NVL144 AI rack is facing a further delivery delay, with a research firm saying the system has been pushed back to 2028 after a manufacturing issue tied to a key circuit board.

The report, carried by Quartz, attributed the setback to problems producing a critical circuit-board component used in the rack’s configuration. SemiAnalysis said the delay amounts to more than 12 months, a timeline shift that could compress how quickly finished systems move from factory lines into customer deployments.

The Kyber NVL144 is a “rack” product, meaning a standardized, pre-integrated cabinet of compute and supporting hardware designed to be installed into data centers as a unit rather than assembling the infrastructure from individual parts on site. For AI builders, rack-level delivery timing can matter because it affects when data center capacity can be commissioned and when customers can scale training and inference workloads.

Quartz also said the delay is weighing on supplier stocks, pointing to broader market sensitivity to disruptions in AI hardware supply chains. When a component bottleneck emerges, investors often reprice expectations for revenue timing among makers of electronics and subassemblies that feed the final system integrators.

Nvidia, for its part, did not disclose details of the reported Kyber-specific manufacturing issue in the Quartz account, and the report did not provide names of affected suppliers or quantify the magnitude of the stock moves.

For the broader technology sector, the episode underscores how AI infrastructure is still dependent on complex manufacturing yield and component availability, even as demand for accelerated compute remains strong. Racks and other system-level products can be held up by a single constrained component, especially where the design requires specialized boards and tight quality control.

What remains unclear from the published report is whether the delay reflects a temporary yield shortfall, a redesign, or a sourcing substitution for the affected circuit board. The Quartz write-up also did not spell out whether the change impacts all customer configurations of the NVL144 or only specific production runs.

Investors and customers will likely watch for follow-up guidance from Nvidia and its manufacturing partners on revised delivery schedules, any changes to bill of materials for the circuit board, and whether supplier-level constraints begin to ease in coming quarters.
