• Technical Expertise: The company specializes in "rejecting thermal heat" in complex, high-compute environments.
• Supply Chain Resilience: To meet the demands of massive projects like "Terafab," the company utilizes a triple-source supply chain, maintaining 99–100% delivery rates.

3. IPO Strategy and Financial Governance

The IPO serves as a mechanism to access permanent capital to underwrite future growth and scale the company’s mission.

• Debt Management: 100% of IPO proceeds are earmarked for debt retirement. The company aims to reduce leverage from approximately 3.5x trailing EBITDA to below 3x by the end of 2026, and below 2.5x by the end of 2027.
