Company Background

Water scarcity is a pervasive challenge affecting primary components of global ecosystems such as energy, agriculture, logistics, transportation, decarbonization, and food. Almost two thirds of the world's population experiences water scarcity for at least one month each year and the gap in supply of water and demand is expected to grow to 40% by 2030.

RET aims to develop, manufacture and commercialize ionization rainfall generation technology to provide additional rainfall for industries, supranational organizations, countries and localities. The Company's ionization technology is rooted in simple, existing physics theory using natural conditions, and has robust datasets produced and evaluated during prior trials by third parties. In a six-year randomized third-party trial conducted from 2013 to 2018 in Oman, an ionization rainfall generation system generated an average of approximately 16% of additional rainfall, according to results published by the National Institute for Applied Statistics Research Australia ("NIASRA"), a third-party research organization, in the International Statistical Review. RET has licensed the engineering designs for the equipment and systems used in the trials.

RET has developed relationships with private organizations, country leaders and major agriculture companies to build a pipeline of potential customers. RET management believes the Company is well-positioned for the development, innovation, and scaling of its rainfall generation technology.

RET has established a strategic roadmap and multiple vectors for development, innovation and enhancement. In addition to its exclusive license of certain relevant underlying IP, the Company intends to draw on the services of leading engineers, scientists, climatologists and experts in the water technology and rainfall generation space. Recent advancements in understanding cloud condensation nuclei and more precise weather forecasting serve as catalysts for increasing the potential enhancement of RET's technology, creating even greater confidence in the efficacy of the ionization approach. This foundation is expected to empower RET's management to swiftly establish commercial alliances with private industries and governments, while involving key stakeholders invested in ecosystem maintenance and restoration in water-stressed areas across the world.

Management Commentary

Chris Riley, interim Chief Executive Officer of RET Holdco, stated, "We are incredibly proud to complete this transaction and become a U.S. listed company. This transformative step enables the next phase of growth at RET. We look forward to executing on our next chapter of growth, innovation, global expansion, and market leadership."

Harry You, Chairman of the Board of Coliseum, stated, "As a public company, RET Holdco is well-positioned to help meet the global demand from private industries and governments for sustainable access to water. We are confident that the Company's rainfall ionization platform will not only play a role in addressing this demand, but also ultimately generate value to all of its stakeholders. We look forward to further innovating and deploying RET's technology as well as other cutting edge technologies."

Management and Governance

Mr. Riley, a veteran C-suite leader with experience spanning both public and private sector companies, brings a wealth of leadership experience accumulated over more than three decades in various technology sectors, including IT, Cloud, Security, Automation and AI. Previously, he served as President, Worldwide Field Operations for DataRobot, as Chief Revenue Officer and Strategic Advisor to the CEO at Automation Anywhere, and in varying roles at Dell, Dell/EMC and EMC (NYSE:DELL, NYSE:EMC), including President Americas Sales and Customer Operations, President Dell Technologies Select and SVP Global Alliances.
