SciDev CEO Seán Halpin said: “We’ve had a reasonably strong quarter despite challenging market environments. Operationally, we’ve expanded our water tech footprint in the US, securing a breakthrough, important first contract for PFAS remediation on multiple Department of Defence installations. This positions us to take advantage of the rapidly growing market for sustainable water treatment solutions.

“While in the US, drilling and completion activities remain volatile given recement movements in commodity prices, and we expect these market conditions to persist through the remainder of FY25. Notwithstanding, the demand for our propriety chemistry remains strong regardless of commodity prices, with our Energy Services business delivering new work wins and growth in market share. This progress demonstrates our ability to grow despite challenging market conditions.”

“The volatility and turbulent market conditions we’re seeing may see the timing of some revenues shift into early FY26, due to customer-led schedule changes and extended delivery windows across each of our business units. These impacts do not reflect any change in demand or scope, and we remain confident in the underlying fundamentals of the business

“As announced during the quarter, the ASX have lifted the requirement for SciDev to report on a quarterly basis. We will continue to keep the market informed of key developments and meet our disclosure requirements while providing detailed updates at the half year, full year and our AGM.”

The Board of SciDev Limited authorises this announcement.
