Boost Run Achieves NVIDIA Exemplar Cloud on NVIDIA Blackwell Architecture^TM

Joining an Elite Tier of Global AI Infrastructure Leaders

Boost Run Becomes One of Only a Handful of Cloud Providers Worldwide to Earn NVIDIA's Highest Standard of Cloud Performance Validation

NORTHBROOK, IL - April 13, 2026 - Boost Run, LLC ("Boost Run"), an NVIDIA Cloud Partner ("NCP") and Preferred Cloud Service Provider that has entered into a definitive agreement to merge with Willow Lane Acquisition Corp. ("Willow Lane") (Nasdaq: WLAC) and is expected to trade on the Nasdaq Stock Market LLC ("Nasdaq") under the symbol "BRUN" upon completion of the transaction, today announced it has achieved NVIDIA Exemplar Cloud on NVIDIA Blackwell^TM architecture - one of the most rigorous technical certifications in artificial intelligence infrastructure. With this milestone, Boost Run joins an exclusive group of cloud providers globally to earn this designation, including CoreWeave, Nebius, Oracle Cloud Infrastructure, and Microsoft Azure.

The NVIDIA Exemplar Cloud program recognizes cloud platforms that demonstrate reproducible, world-class AI workload performance at scale using NVIDIA Performance Benchmarking. To achieve validation, a provider must demonstrate that its infrastructure delivers results within 5% of NVIDIA's own reference performance targets - across real-world training workloads, production-grade software stacks, and massive multi-GPU configurations.

"Achieving NVIDIA Exemplar Cloud is validation of what we are committed to delivering the highest caliber of performance for our enterprise users - infrastructure that doesn't just promise performance, it proves it," said Andy Karos, Founder and CEO of Boost Run. "Our customers in regulated industries - finance, healthcare and amongst others - demand the highest levels of performance predictability, security, and compliance. NVIDIA Exemplar Cloud validation gives them independent, reproducible confirmation that Boost Run delivers. It is a distinction to stand alongside some of the largest cloud providers in the world to earn this distinction."

"The NVIDIA Exemplar Cloud achievement is a testament to Boost Run's commitment to delivering leading AI infrastructure," said Warren Barkley, Vice President of Product Management at NVIDIA. "The Exemplar Clouds initiative sets a transparent standard for performance and resiliency, and we congratulate Boost Run for embracing a high standard of workload performance in their infrastructure."

What NVIDIA Exemplar Cloud Means

The NVIDIA Exemplar Cloud initiative was established to bring transparency and accountability to AI cloud performance - cutting through subjective claims with standardized, reproducible benchmarks. Rather than relying on synthetic microbenchmarks, the initiative evaluates real AI training workloads using large-scale LLM scenarios, production-grade software stacks, and workload-centric metrics including throughput and time-to-train. Exemplar-validated providers must demonstrate:

● Reproducible performance on NVIDIA Blackwell benchmarking recipes across large-scale LLM training and inference workloads

● Infrastructure consistency from single nodes to multi-thousand GPU configurations

● Full-stack optimization across compute, networking, and system software aligned to NVIDIA Enterprise Reference Architectures

● Performance within 5% of NVIDIA's own target results

Fewer than a handful of cloud providers worldwide have achieved this validation. Boost Run is now among them.

Purpose-Built for the Most Demanding Workloads

Boost Run's Exemplar Cloud validation was achieved on its NVIDIA HGX^TM B300 infrastructure, which operates out of secure and certified data centers. Boost Run's purpose-built colocation footprint - spanning Charlotte, Raleigh, Dallas, Seattle, and Eagan - provides the foundation for AI infrastructure that performs at the highest levels while meeting the compliance requirements of the world's most regulated industries.

A Defining Moment for Enterprise AI Infrastructure

NVIDIA Exemplar Cloud carries particular significance for enterprise and regulated-industry customers who cannot afford unpredictable performance or unverified infrastructure. For Boost Run's customer base - which spans financial services, healthcare, defense, and frontier AI research - this certification provides an independently verified performance baseline that no marketing material can replicate.

"This is about accountability," Karos continued. "The benchmarks are public. The results are reproducible. Customers can run NVIDIA's own tests on our infrastructure and see for themselves. That level of transparency is the standard we have always held ourselves to, and now NVIDIA has confirmed it."
