Oklo whipsaws amid BofA downgrade, accelerated future review process by the Nuclear Regulatory Commission

Shares of Oklo were volatile in early trading, falling as Bank of America downgraded the stock to neutral from buy before getting a short-lived jolt after the nuclear technology company said regulators accepted a key design report faster than anticipated. The stock is down about 3% as of 10:05 a.m. ET.

“Valuations now embed deployment ramps and discount rates we view as unrealistic at this stage of SMR [small modular reactor] adoption,” BofA analyst Dimple Gosai wrote. “While we remain constructive on Oklos differentiated build-own-operate model, pipeline conversion, HALEU recycling, and DOE/DoD contracting, we view near-term risk/reward as balanced.”

She also raised her price target to $117 from $92.

Separately, the US Nuclear Regulatory Commission accepted Oklo’s Principal Design Criteria topical report “in just 15 days, compared to the typical 30–60 days following submission,” the company shared in a press release, noting that “recent legislation and executive orders have called for the delivery of more nuclear power for clean, reliable energy on accelerated timelines, and this is how it’s done.”

Per the company, the PDC report establishes a regulatory framework for future reactor licensing and design activities, and once approved, effectively streamlines Oklo’s deployment of advanced reactors by reducing unnecessary steps in the licensing process.

In a note published on Monday, Barclays analysts wrote that “government approval of each step of the process is one of the largest moats in the space,” especially considering the “prolonged, expensive, and complex” regulatory framework under the NRC.

Oklo is up 65% in the past month, riding a wave of investor enthusiasm for clean power plays as the market anticipates a surge in AI-related energy demand. Earlier this morning, shares were under pressure after BofA cut the stock to “neutral from buy.

Michael Burry flags “troubling” jump in Nvidia’s supply commitments

The Big Short investor Michael Burry — famous for betting against the 2008 housing bubble — just warned of a major risk in Nvidia’s latest annual report, pointing to a sixfold surge in purchase obligations over the past year.

In a Substack post Thursday, Burry called the increase from $16.1 billion to $95.2 billion in just 12 months troubling, noting that Nvidia has been forced to place noncancelable purchase orders well before knowing the final demand for its AI chips. The surge is partly tied to supplier TSMC requiring longer-term contracts, he added.

Vistra beats Q4 earnings expectations for adjusted EBITDA, but dips on income decline

Power provider Vistra, a key player in the AI energy trade, reported better-than-expected adjusted earnings results early Thursday, but shares dipped in early trading as Q4 net income dropped.

The Texas-based company, which supplies nuclear- and natural gas-fueled power to wholesale and retail markets, reported:

  • Net income of $233 million, a decline of 52% from Q4 2024.

  • Adjusted EBITDA from ongoing operations of $1.74 billion vs. the $1.71 billion expected by Wall Street analysts.

  • Vistra maintained previously issued guidance for full-year EBITDA from ongoing operations and adjusted free cash flow from ongoing operations.

Vistra shares soared 258% in 2024 amid a flurry of excitement over the AI energy boom. Last year was more muted, with the stock rising 17%. So far in 2026, shares were up roughly 9% before the report.

Sandisk rises on partnership with SK Hynix to standardize memory chip architecture tailored for AI data centers

Sandisk is up 3% in premarket trading on Thursday after it began its global standardization strategy of high-bandwidth flash (HBF) memory solutions with SK Hynix.

SK Hynix commented in a press release on Thursday that by making HBF an industry standard, together with Sandisk, we will lay the foundation for the entire AI ecosystem to grow together,” adding that the companies will set up a dedicated workstream to work on the standardization under the Open Compute Project, the world’s largest organization dealing with data center technologies.

First debuted last February, Sandisk’s HBF technology lies in between ultrafast high-bandwidth memory (HBM) and high-capacity SSDs. That is, these have more storage capacity than HBMs, but are still fast enough to be utilized in AI inferencing (albeit not as quick as HBM).

Sandisk has previously argued that this hybrid architecture is central to AI services that need user applications but require a significant amount of fast interconnect between GPUs. The latest announcement also notes that HBF technology is expected to be more cost-efficient compared to alternatives of similar scale.

The launch, which was shared in an kickoff event on Thursday evening, starts SK Hynix and Sandisk’s workflow, which was announced when the two companies signed a memorandum of understanding “to standardize the specification, define technology requirements and explore the creation of a technology ecosystem” last August, per Sandisk’s press release at the time. Ultimately, by collaborating with SK Hynix, one of the three key HBM suppliers, to standardize and commercialize the technology, Sandisk is manufacturing somewhat of a first-mover advantage to offer the system-level “AI-optimized memory architecture” required for AI inference markets, rather than focusing on the performance of a single chip element.
