"I'm honored to join Rain Enhancement Technologies at such a pivotal moment in the Company's evolution," said David Sylvester. "RET's mission to address global water scarcity through proven, scientifically validated technology represents both a tremendous societal opportunity and a compelling growth story. The Company's innovative approach to weather enhancement has the potential to transform water access for agriculture, municipalities, and industries worldwide.

Sylvester's appointment reflects RET's commitment to assembling a board with diverse expertise spanning technology, meteorology, operations, finance, and the Company's key target markets. As RET continues to scale its precipitation generation technology globally and advance strategic partnerships with governments and industries, Sylvester's financial leadership and public company experience will provide critical guidance during this phase of commercial expansion.
