Executive Commentary

Unison Co-Founder and Co-CEO Andy Cooper said, "Unison provides tailored solutions for commercial and industrial businesses seeking to address rising energy costs, power resiliency challenges, and carbon emissions reductions. We leverage our proprietary systems and in-house engineering and operation & maintenance expertise to play a critical role in power generation and decarbonization. We have been expanding our offering to include on-site carbon capture and other in-demand solutions. We believe Unison is well-positioned to become the partner of choice for customers seeking a reliable, long-term solution to reduce cost, enhance resiliency, and decarbonize operations."

Unison Co-Founder and Co-CEO Tim Lukes remarked, "We knew the Tiger team prior to this transaction and during this process confirmed their deep experience in energy transition, experience with similar business models, and track record of partnering with teams to build and scale platforms. As a result, we determined that Tiger would be the ideal partner. We are excited to provide creative solutions to our customers with the support of Tiger."

Tiger CEO Emil W. Henry, Jr. said, "The role of reliable, resilient, on-site power generation is becoming increasingly sought after as the global energy transition continues apace. We believe that Unison is benefiting from long-term secular tailwinds including an aging grid that is increasingly burdened by the growth of renewable energy and a demonstrable step-change in demand for power driven by artificial intelligence and a drive towards onshoring certain elements of US manufacturing. We are excited to partner with the Unison team to support the Company in its next phase of growth and capitalize on the strong and growing demand for access to more dependable, consistent, cost-effective and lower-carbon power."
