System Demonstrates Reliable Performance Through Historic Drought

NAPLES, FL / ACCESS Newswire / March 31, 2026 / Rain Enhancement Technologies Holdco, Inc. (NASDAQ:RAIN), a leading provider of ionization precipitation generation technology, today announced continued measurable snowpack enhancement from its Utah installation through the winter 2025-2026 season. The Company's Weather Enhancement Technology Array (WETA) system demonstrated consistent performance across three consecutive months (December 2025, January 2026, and February 2026) during one of the driest winters in recent Western U.S. history.

February 2026 results showed snowpack enhancement of 2.4 inches and snow-water equivalent gains of approximately 1.4 inches at the treatment site in the La Sal Mountains compared to the control site in the nearby Abajo Mountains. The February data, evaluated against the five driest February months from the past decade, continues the pattern of measurable enhancement established in December and January, providing cumulative validation of the technology's effectiveness during extreme drought conditions.

The snow-water equivalent gains are particularly significant given the extreme conditions during the measurement period. Despite record-warm temperatures causing ongoing snowpack melt and declining accumulated precipitation across the region, the treated areas maintained measurably higher water content than control sites, demonstrating the technology's effectiveness even under the most challenging environmental conditions.

"Three consecutive months of measurable enhancement during one of the most challenging winters on record demonstrates both the technology's reliability and its value for water-stressed regions," said Randy Seidl, CEO of Rain Enhancement Technologies. "This consistent performance provides the kind of sustained validation that water managers and policymakers need to make infrastructure decisions. We're not seeing isolated results; we're seeing a pattern."

"The fact that we're seeing enhanced snow-water equivalent during a period of active snowmelt due to warm temperatures underscores the value of this technology during drought conditions," said Scott Morris, Chief Technical Officer of Rain Enhancement Technologies. "Water managers care about water content, not just snow depth. These results show that the technology is delivering meaningful water resource enhancement precisely when it matters most."

The winter of 2025-2026 has been marked by record-warm temperatures and unusually dry conditions across the Western United States, with Utah experiencing particularly severe impacts. Mountain snowpack serves as a critical water reservoir for the region, with 95% of Utah's water supply originating as snow that gradually melts and feeds rivers, reservoirs, and the Colorado River system.

Local water authorities monitoring the La Sal Mountains installation have observed the broader implications of enhanced snowpack for regional water security.

"Just a little bit of difference is a big deal to the water users in the Colorado River basin as well as the local people," said Gary Wilson, Chairman of the Grand Water and Sewer Service Agency. "All this ends up in the river and down to Arizona and California. There's a lot of potential here."

The Company's analytical approach compares snowpack, snow-water equivalent, and precipitation data from treatment sites at La Sal Upper and La Sal Lower SNOTEL stations against control sites at Buckboard Flat and Camp Jackson in the Abajo Mountains. By evaluating 2026 performance against the driest historical years, the methodology establishes conservative baselines for measuring enhancement effects. The consistent results across three months strengthen statistical confidence in the technology's performance.
