Future Outlook

The company expects the business combination to close in the second half of 2026, leading to the formation of Exascale Labs Holdings Inc. and a Nasdaq listing under the ticker XLAB. Management anticipates continued demand for AI compute infrastructure and is positioning its SST and HVDC technologies as critical solutions for future data center power requirements.

Management Comments

• AI is forcing every layer of data center infrastructure to be redesigned, from compute and cooling to power and deployment.
• The next major bottleneck is power. SST and HVDC architectures are becoming increasingly important because they can help data centers support higher-density AI workloads with greater efficiency, faster deployment, and a more compact electrical footprint.
• SST is not simply a component upgrade. It is part of a broader architectural transition toward AI data centers that are more modular, more power-dense, and more efficient from the grid connection to the GPU rack.

Industry Context

StockSavvy.ai notes that this announcement aligns with the broader industry trend of shifting focus from pure GPU procurement to holistic data center power management. As AI clusters scale, power delivery and cooling have become the primary constraints, mirroring the earlier evolution of optical interconnects in high-performance computing.

Comparison to Industry Standards

• The focus on SST and HVDC architectures positions Exascale alongside specialized power electronics and infrastructure providers serving the hyperscale data center market.
• The strategy of integrating power, cooling, and compute into a modular stack is consistent with current industry efforts by major data center operators to optimize for high-density AI workloads.

Stakeholder Impact

• Shareholders of BCAR are encouraged to review the S-4 registration statement and upcoming proxy materials.
• Industry partners and customers may gain insight into Exascale's technological roadmap through the upcoming forum presentation.

Next Steps

• Presentation by Dr. Hoansoo Lee at the Guosheng Securities SST Industry Forum on May 29, 2026.
• Completion of the proxy statement/prospectus review by shareholders.
• Finalization of the business combination expected in the second half of 2026.
