Desert Control Provides Mid-Year Update

Desert Control Provides Mid-Year Update

Sandnes, Norway, 21 July 2025 - Desert Control (DSRT) today provides an

operational update

Operational Update

Recent applications of the company's Liquid Natural Clay ('LNC") at Woodland

Hills Country Club and PGA West have experienced operational challenges, related

to irrigation systems on the sites and residual LNC not being distributed as

intended.  The company is conducting analysis on both incidents and preliminary

results show that reliability issues with certain secondary equipment and

operator miscommunications were the likely causes of each matter. Importantly,

both properties remain fully operational, and Desert Control and the clients are

fully committed to resolving any residual effects. Applications at California

State University- Fullerton and Mesa del sol Golf Course were conducted without

any challenges

Manufacturing schedule update for the new LNC production unit

The company remains committed to producing initial units of the new design, high

volume production system modules, in the second half of 2025.  The process has

been delayed by personnel shortages at Desert Control and longer processing time

than anticipated with certain vendors.  The company recently added a senior

resource in the US to help accelerate manufacturing and other supply chain

programs. Further, while some modifications may be made to the system's

peripheral equipment - clay loading and tanks, - as a result of the ongoing

analysis  no change is expected in the fundamental core production modules.

Withdrawal of Revenue Guidance for 2025.

Until the company has completed its analysis and implemented solutions to issues

discovered, no additional, large-scale applications in the Golf segment are

expected to be initiated in 2025 and the company is, therefore, withdrawing its

previous 2025 revenue guidance.

Emerging Data on LNC's ability to increase crop yield

While much of the company's research to date has been focused on the water

saving benefits of LNC, the product's ability to also positively impact crop

yields has been both a scientific and commercial goal.  Yield increases have

been seen in several small studies in both the Middle East and the United

States, but larger, well controlled studies have been limited in number.  Recent

data coming from our work with the University of Arizona Maricopa Research

Center on both Broccoli and Cantaloupe show encouraging increases in yield in

fields treated with LNC.

Release Date for Second Quarter Report

The company will now release its second quarter report on August 15[th] 2025

versus the prior date of August 27, 2025.

"The operational challenges at Woodland Hills Country Club and PGA West are

frustrating for our customers, our shareholders, and our dedicated team," said

James Thomas, CEO of Desert Control. "While some unintended impact on irrigation

infrastructures has occurred, it's however important to note that over 4.5

million liters of LNC was applied at Woodland Hills, and the total residual

matter identified is measurable in pounds. Moreover, we have not observed

similar complications at other recent applications, including those at Oasis

Dates and Cal State Fullerton."

"Our customers remain confident in LNC's ability to enhance soil health and

water retention," Thomas added. "However, we recognize the need to further

refine our delivery capabilities particularly for high-pressure, high-flow

irrigation environments."
