NAPLES, FL AND SUNNYVALE, CA / ACCESS Newswire / September 23, 2026 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ:RAIN), the leading provider of ionization weather modification technology, and Tensor Networks, Inc. ("Tensor Networks"), a privately held developer of predictive AI technology built around the company's "Safe AI" approach to infrastructure security, today announced that they have entered into a binding letter of intent (the "Binding LOI") for a business combination that would result in Tensor Networks becoming part of RAIN's publicly traded holding company upon closing. The transaction is anticipated to close in the first quarter of 2027, subject to customary closing conditions.

"When we brought this platform public, we said that our corporate structure was designed to allow us to acquire additional businesses or assets alongside Rain Enhancement Technologies, Inc. ("RET") - Tensor Networks is a cutting-edge technology company that is exactly that kind of opportunity," said Harry You, Chairman of the Board of RAIN. "As AI adoption accelerates across every sector, the security and reliability of the infrastructure underneath it is becoming a defining issue, and Tensor Networks has built real, patent-pending technology to address it. RET's work with data center customers is accelerating, and water is an increasingly important part of that conversation. Tensor Networks addresses a different piece of that same infrastructure picture, and having both under the RAIN platform gives us real depth in a market that matters more every year."

"This transaction is an important next step in building RAIN into a multi-technology platform," said Randy Seidl, Chief Executive Officer of RAIN. "Tensor Networks gives us a second growth engine alongside RET, and we believe that diversification is the right way to build long-term value for RAIN shareholders. I'm looking forward to partnering with Eric as we move quickly toward a definitive agreement."

Founded in 2019, Tensor Networks develops predictive AI infrastructure technology, including its patent-pending Predictive Tensor Control Plane (PTCP) and Tensor Network Quantum Gravity (TNQG) frameworks. Tensor Networks describes its approach as "Safe AI". PTCP combines predictive workload orchestration with topological caging, an approach designed to isolate AI workloads behind independent hardware boundaries intended to help contain threats and limit data exfiltration or lateral movement across AI infrastructure.

Upon closing, RET and Tensor Networks would each continue to operate as a wholly owned operating subsidiary of RAIN, pursuing its own commercial strategy under its own management team, rather than being operationally merged with one another - RAIN becoming a multi-technology holding company, not a combined rainfall-and-AI business. Each of the operating companies will leverage shared general and administrative resources.

The transaction also reflects the growing importance of securing the infrastructure that powers artificial intelligence. As AI adoption accelerates across government, defense, and enterprise networks, the systems that route and process AI workloads have become an increasingly attractive target. Tensor Networks says PTCP is designed to work alongside existing enterprise security platforms (SIEM) and to trigger hardware-level safeguards intended to help contain threats and limit lateral movement - an approach the company has developed and tested in part through three U.S. Air Force contracts it has been awarded and delivered against.

"As AI capabilities scale, security can't be an afterthought bolted onto legacy software," said Eric Frazier, Founder and Chief Executive Officer of Tensor Networks. "We built Tensor Networks around the idea of Safe AI - using independent hardware boundaries designed to help contain threats at the source, not just flag them after the fact. Joining RAIN gives us the platform and capital to bring that approach to a much broader market, and I'm confident this combination will create real value for our shareholders and customers alike."

Transaction Highlights:

• All-stock transaction, with 100% of Tensor Networks' securities rolling into RAIN
• Tensor Networks' equity holders expected to own approximately 90% of the fully diluted equity of the combined company, with RAIN's existing shareholders retaining approximately 10%, in each case prior to dilution from the contemplated financing described below
• RAIN's outstanding debt to be converted, restructured, or forgiven on mutually agreeable terms prior to or concurrently with closing
• A minimum of $25 million in gross proceeds from an equity or equity-linked financing is a condition to closing; net proceeds are expected to fund Tensor Networks' growth and working capital
• Eric Frazier, Founder and CEO of Tensor Networks, will become Chief Executive Officer of RAIN; Randy Seidl, CEO of RAIN, will become President of RAIN, both reporting to the Board of Directors
• RAIN insiders, Tensor Networks insiders, and Tensor Networks employees will be subject to lock-up agreements of 12-18 months following closing
• The transaction remains subject to due diligence, negotiation and execution of a definitive transaction agreement, Nasdaq granting RAIN's pending request for continued listing, Nasdaq approval of the combined company's initial listing application, and other customary closing conditions
