Management Comments

We also believe that most current alternatives have not been architected with this same focus and intent as we have here at Boost Run as the world moves to multi-cloud solutions."
• Andrew Karos, Boost Run Founder and CEO: "We believe entering the public markets can provide us with both the capital and access to competitive financing we need to accelerate our strategy, expand our share in focus areas such as government and regulated industries, and productize our software and automation layer at scale. With over $145 billion in private capital raised since 2024 for AI-specific applications and new GPUs being introduced that will power more use cases, we believe our time is now."
• Luke Weil, CEO and Chairman of Willow Lane: "Our focus has always been to identify and work with high integrity hands-on operators with a meaningful track record of value creation. We believe that the demand outlook for AI cloud infrastructure is a meaningful long-term secular trend, and that the few winners will be those providers that: come with a deep understanding of cost and pricing curves, have favorable access to top tier data center providers and server suppliers, can build secure enterprise grade solutions for an increasingly sophisticated user base, can deploy, price, and manage to a high return on invested capital and free cash flow margin."
• Luke Weil, CEO and Chairman of Willow Lane: "Andy and his team have built a capital efficient business, converting approximately 70% of their capital expenditures to revenues, driving over 75% adjusted EBITDA margins and a high teens free cash flow margin."

We understand that demand at that price significantly exceeded supply, underscoring confidence in our merger plan from institutional investors very well-versed in AI cloud infrastructure. We're also excited that this transaction provides public investors access to an early-stage, pure-play AI cloud infrastructure story."
