Rainwater Tech ? Innovator in Rainfall Generation Technology ? to Become Publicly Traded through a Business Combination with dMY VI

Rain Enhancement Technologies, Inc. ("Rainwater Tech"), a leader in the development of rainfall generation technology, and dMY Technology Group, Inc. VI (NYSE: DMYS) ("dMY VI"), a publicly traded special purpose acquisition company, today announced that they have entered into a business combination agreement.

Upon closing, the combined company is expected to retain the Rainwater Tech name. Once the business combination is completed, dMY VI will change its trading ticker from DMYS to the new ticker symbol "RANY."

Water Supply and Demand Imbalance Worsening

Increasing water scarcity challenges are seen in nearly every populated area on the globe. Crop yields are adversely impacted with inadequate access to water. Forest fires can disrupt whole states, unraveling centuries of natural carbon capture. Access to potable water has become a social justice and economic development issue not only in developing countries, but also in many developed nations. As geopolitical events have unfolded over the past year, the world is increasingly focused on water's elemental role in human and animal survival, food inflation, supply chain disruption, and energy. Alternative technologies to increase our water tables such as desalination and chemical cloud seeding possess considerable environmental, energy density, political, transportation and scalability challenges. Over the past few decades these alternatives have largely failed to prevent the acceleration of water scarcity all across America and Western Europe.

Rainwater Tech is led by world class pioneering scientists, entrepreneurs and proven public company leaders collaborating on a joint mission to help rebuild the water table for cities, government and industry. Third party trials of the pre-existing technology, called ground-based ionization for rain generation, have demonstrated the ability to enhance rainfall by as much as 9%-18%, according to news reports. At the same time, the company's commercial team has engaged and validated a strong customer base that is ready to leverage this rainfall ionization platform. Rainwater Tech is poised to develop, innovate and scale rainfall generation technology.

Rainwater Tech is led by co-founder and veteran public company CEO, Mike Nefkens, who previously ran the public industrial conglomerate Resideo Technologies and HPE Enterprise Services ? a $20 billion, 100,000 person organization. At HPE, Mr. Nefkens was personally involved in the closing of over $30 billion in commercial contracts, helping to drive growth and ultimately culminating in the spin-off of the business at a $13 billion valuation in 2017. From 2018-2022, Mr. Nefkens was the CEO of Resideo Technologies (NYSE: REZI), a spin-off of Honeywell (NYSE: HON) with approximately $5 billion in revenue and 12,000 employees. Mr. Nefkens has strong global Fortune 500 customer relationships and is experienced in scaling organizations and building exceptional teams.

Rainwater Tech has established a roadmap and multiple vectors for development, innovation and improvement. The company has licensed certain relevant underlying IP as well as secured the services of leading engineers in the water technology and rainfall generation space. Over the last few years, scientific understanding of cloud condensation nuclei and the water cycle have advanced to the stage of global agreement on the underlying mechanisms. This foundation will allow Rainwater Tech's team to expeditiously advance commercialization alliances between private industry and government, including companies looking to reduce the impairment of property and land, supranational organizations, localities, developed nations exposed to high water stress, and developing nations that can make use of World Eco funds.

"Our vision is to be the first company of its kind in the water and climate adaptation space by facilitating the return of rain and moisture where it's needed most," said Mike Nefkens, CEO of Rainwater Tech. "This transaction enables us to develop, innovate and commercialize rainfall generation technology, backed by an expert management group and a best-in-class team of scientists, engineers, and business development leaders. We are excited to partner with dMY VI and leverage their experience in the area of frontier technologies, and to develop and launch to market augmentation technology and make a positive impact for our investors and our planet."

"Rainwater Tech's rainfall ionization platform will be poised to play a major role in increasing the water table for cities, government and industry and is uniquely positioned to meet massive market demand from private industry and governments around the globe," said Niccolo de Masi, CEO of dMY VI. "We are proud to back companies like Rainwater Tech that target high returns on invested capital and, large addressable markets, and are comprised of a team with extensive leadership experience ? with the ability to address one of humanity's biggest challenges."

Transaction Overview

The transaction is expected to result in a pro forma valuation of $200 million.

After paying transaction expenses and the cash consideration, the balance of the approximately $241 million in cash held in dMY VI's trust account (assuming no redemptions), will be used for funding development, innovation and commercial scale.

The transaction, which has been unanimously approved by dMY VI's Board of Directors, is subject to customary closing conditions.
