Shares of IREN Ltd (NASDAQ:IREN) experienced a notable decline of over 6% during trading on Wednesday. This downturn followed critical commentary from the research firm SemiAnalysis, which highlighted serious complaints from users regarding the quality of infrastructure at IREN’s data center facilities.

Details of the Criticism

SemiAnalysis took to social media platform X to share findings from numerous neocloud customers describing IREN’s operational facilities in Prince George and Mackenzie, British Columbia, as “the worst in the industry.” Issues cited included:

• Multi-day power outages
• Problems related to network upgrades
• Storage failures
• Air quality control issues leading to system errors

The firm also conducted its tests on IREN’s GPU capabilities, confirming extensive technical deficiencies at these facilities and gathering reports from third-party resellers that echoed similar concerns.

Future Developments and Infrastructure Improvements

Despite the significant challenges faced with existing structures, SemiAnalysis observed that IREN’s newer developments in locations such as Childress and Sweetwater, Texas, represent notable upgrades. These projects demonstrate enhanced operational standards, differing markedly from previous configurations that were vulnerable.

Furthermore, a substantial investment of $2.1 billion from Nvidia is expected to facilitate improvements in the quality of future infrastructures.

Public Disclosure and Market Standing

SemiAnalysis urged IREN to reassess its public disclosures. The research firm pointed out discrepancies between IREN’s assertions in its latest annual report (Form 10-K)—which claimed comprehensive ownership of its technology stack—and statements from the Chief Commercial Officer acknowledging the lack of live managed cloud services.

In light of these findings, SemiAnalysis recommended that IREN focus on enhancing its bare-metal infrastructure, where demand in the market remains strong.

ClusterMAX Rankings and Industry Positioning

Currently, IREN is rated in the “Not Recommended / Underperforming” category of SemiAnalysis’s ClusterMAX rankings, significantly behind competitors such as CoreWeave Inc (NASDAQ:CRWV) and Nebius Group NV (NASDAQ:NBIS), which hold prestigious Platinum ratings. This criticism underscores the execution risks faced by former cryptocurrency mining companies as they transition their legacy infrastructures to support high-performance AI workloads.
