## Exhibit 99.1

**Exhibit 99.1**

**Exascale Labs to Present at Guosheng Securities SST Industry Forum in Shanghai on May 29, 2026**

● *Exascale to discuss how solid-state transformer and HVDC architectures are becoming critical infrastructure for next-generation AI data centers ahead of its proposed business combination with D. Boral ARC Acquisition I Corp. (NASDAQ: BCAR)* 

**SAN FRANCISCO, May 27, 2026** – Exascale Labs Inc., a leading provider of next-generation AI compute infrastructure, today announced that Dr. Hoansoo Lee, Chief Executive Officer of Exascale Labs, will present at the **Guosheng Securities SST Industry Forum**, titled **"SST: The CPO Moment Arrives for Power Equipment."** The forum will take place on **May 29, 2026**, at the **Grand Hyatt Shanghai in Lujiazui, Shanghai**.

"AI is forcing every layer of data center infrastructure to be redesigned, from compute and cooling to power and deployment," said Dr. Hoansoo Lee, Chief Executive Officer of Exascale Labs. "The industry has spent the past several years focused on GPUs, networking, and optical interconnects. 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."

The forum will convene leading experts across AI data center deployment, power electronics, silicon carbide devices, optical communications, and solid-state transformer system design to discuss one of the most important infrastructure shifts now emerging in the AI era: the transition from traditional data center power delivery to high-voltage direct current and SST-based architectures.

As AI infrastructure moves toward larger GPU clusters, higher rack densities, and next-generation 800V DC power delivery, the industry is beginning to treat the data center as a full power-system design challenge, not only a server procurement challenge. This mirrors what happened in optical communications, where co-packaged optics helped redefine high-speed interconnects for AI and high-performance computing. Exascale believes SST-based power infrastructure may represent a similar architectural shift for power delivery inside next-generation AI factories.

Exascale will showcase its Vera Rubin Data Center stack and is expected to discuss the demand for AI compute infrastructure in North America, the rapid evolution of AI data center architecture, and the role of SST-based HVDC systems in supporting high-density GPU deployments. The company's perspective is grounded in its work across modular data centers, GPU cluster deployment, liquid cooling, power infrastructure, and AI infrastructure operations.

The rise of optical communication companies in the AI infrastructure supply chain has shown how quickly enabling technologies can become central to the buildout of AI data centers. Technologies such as optical transceivers, high-speed interconnects, and co-packaged optics have become critical to moving data between GPUs at scale. Exascale believes power delivery is now entering a similar phase. As GPU clusters grow larger and more power-intensive, the ability to move electricity more efficiently and reliably through the data center is becoming just as strategic as the ability to move data.

"SST is not simply a component upgrade," Dr. Lee added. "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. For companies building at the front line of AI infrastructure, power is becoming a strategic advantage."

Exascale's platform is designed to address the major deployment bottlenecks facing AI infrastructure customers, including compute availability, power density, cooling, modular deployment, and operational optimization. Its core offerings include GPU-as-a-Service, GPU cluster management, modular data center solutions, high-density cooling, HVDC and solid-state transformer power systems, and energy storage solutions designed for large-scale AI workloads.

Exascale entered into a business combination agreement with D. Boral ARC Acquisition I Corp. ("BCAR") in early 2026 and BCAR filed its [S-4](https://www.sec.gov/Archives/edgar/data/2065779/000182912626005168/dboralarcacqmer_s4.htm) with the Securities and Exchange Commission on May 14, 2026. Exascale expects the transaction to close in the second half of 2026, and upon closing, the combined company will operate as Exascale Labs Holdings Inc. The combined company expects to list on Nasdaq under the ticker XLAB.
