1H FY26 vs 1H FY25

▪ Revenue declined 4% YoY, driven by Water Technologies in APAC and Energy Services, partially offset record revenues for Process Chemistry.

▪ Gross Margin was 18% lower YoY, due primarily to weaker margins in Energy Services, which itself was impacted by lower xSlik sales.

▪ Underlying EBITDA of $1.1m, down $2.3m YoY. Two factors caused the variance: frac schedule disruption at a key Energy Services customer ($3.6m impact) and international Water Technologies investment-phase costs (.$0.7m impact) Excluding these two items, all other divisions and corporate improved YoY.

• Reported EBITDA includes $0.7m of one-off costs related to redundancies & restructuring, and ISO asset rectification.

2Q FY26 vs 1Q FY26

▪ Revenue improved 9% QoQ, while underlying EBITDA improved by $1.1m, with higher gross margins across all businesses.

Other Key Items

• A focus cost reduction program, initiated in 2Q, drove a $0.7m reduction in underlying SG&A YoY, with a total of $1.3m in annualised fixed costs removed.

▪ Net Cash remained a healthy $4.4m positive as at 31 Dec 2025.

Total	1.1	3.4	-68%

Negative Drivers

Underlying EBITDA of $1.1 million was $2.3 million below the prior corresponding period. Two factors account for the entire variance:

• Energy Services: ($3.6m lower YoY) A single key customer changed their frac schedule during the half, materially impacting sales of xSlik®, our premium specialty friction reducer. Moving forward, the customer relationship remains intact with opportunities for sales resume in FY27.

• International Water Technologies: ($0.7m lower YoY) Direct investment costs grew faster than revenues. Actions were taken to restructure the business, replacing a direct-investment model with a channel partner approach, materially lowering fixed costs, saving up to $3 million pa from 2H FY26.

Positive Drivers

Excluding the two items above, all other business units improved:

• Process Chemistry: Record revenue of $14.5 million, up 16% and underlying EBITDA up 58%, driven by tunnelling infrastructure contracts.

• APAC Water Technologies: Returned to profitability with underlying EBITDA of $0.2 million, up $0.8 million YoY. The improvement reflects a positive shift to higher-margin technology services, and O&M contract revenues.

==> picture [105 x 21] intentionally omitted <==

• Corporate costs: Down 19% year-on-year to $1.9 million through headcount and administration savings. Reductions are expected to be maintained.

Revenue	25.9	27.6	-6%
EBITDA Underlying	3.3	6.5	-49%

Highlights

• Revenue $25.9m down 6%, due to primarily to frac schedule disruption at a key customer.

• Underlying EBITDA $3.3m (vs $6.5m in 1H FY25): Margin compression reflects xSlik® volume loss and fixed distribution cost absorption at lower revenue.

• CatChek® client base +75%: CatChek® customers grew materially following Permian Basin expansion, with additional business development resources added to target the market.

• Energy market context: WTI pricing has generally been supportive of completion activity. Management notes the key 1H FY26 headwind was customer-specific scheduling, not commodity-driven.

• Integration of 25 new branded ISOs deployed to strengthen on-site delivery and lower distribution costs.

Strategy & Outlook

• Increasing presence in target basins, supported by additional business development resources, creates potential for new customer acquisitions in 2H.

• Medium-term growth: US shale gas production expected to rise significantly as infrastructure comes online in 12–18 months.

Highlights

APAC

• Revenue of $7.0m, down 25%, as several D&C contracts rolled off, and prior to ramp up of the new Rum Jungle contract ($1.0m in related revenues in 1H).

• Underlying EBITDA improved $0.8m YoY, due to a positive mix of higher margin technology-based revenues, including remote WQMS devices and IoT linked Hydra-IQ portal in the period.

International

• Revenue increased 19% YoY off a low base, from PFAS projects in Europe.

• Underlying EBITDA declined to a loss of $1.5m, as cost growth outpaced earlystage revenues.

Strategy & Outlook

• Revenues expected to grow substantially as work on the $19.5m Rum Jungle contract picks up, with the project scheduled to finish in September 2026.

• High confidence in replenishment of our D&C order book, including Rum Jungle, based on sole-source engagement for design work with major mining clients.

• Transition to a new low-cost operating model for the International businesses in the US and UK expected to reduce fixed costs by up to $3.0m annually.

• Growing interest from major Data Centre developers to deliver critical Reclaimed Water solutions.

Balance Sheet

• Working capital 3% lower YoY, broadly inline with change in revenues.

• Property, plant, and equipment (PPE) down 3% YoY, reflective the low sustaining capital needs of the business. Capex for PPE in the period related primarily to investment in ISO tanks for Energy Services, moving from rental to ownership.

• Net cash of $4.4m as at 31 Dec 2025 remained healthy, albeit impacted lower earnings during the period and

• Unutilised debt facilities of $6m as of 31 Dec 2025.

Cashflow

• Reported operating cashflow of ($0.7m) included several abnormal items in the period including due diligence cost paid, but incurred in FY25, and several abnormal expenses relating to redundancies & restructuring and ISO repairs.

• Capex for PPE of $0.5m, half was comprised of a broad range of small projects distributed across the group.

• Sustaining capex is expected to run well below headline depreciation rates due to the long-lived nature of BOO assets which form the majority of PPE.

• Positive operating cashflow in 2Q FY26 expected to continue into 2H FY26.

Outlook – FY26
Guidance revised reflecting recent challenges, with upside potential retained
----- End of picture text -----

Revised Guidance

Downside Risks

• The revised guidance reflects the company’s view of reasonable downside risk.

FY26 Revenue guidance revised to $100m - $110m, reflecting:

• Recently confirmed delay in sales opportunity for xSlik® pushed into FY27.

• Delays to trial conversions in Process Chemistry confirmed in February.

• $3 million negative impact from higher AUD:USD on forecast USD revenue.

• Downside risks included in the guidance cover key items such as one month movement of revenues from Rum Jungle into FY27, and delays to onboarding new Energy Services customers scheduled in 4Q FY26.

Upside Opportunities

• Upside opportunities not included in the forecast cover:

Energy Services:

2H FY26 EBITDA expected to be higher than 2H FY25 , supported by:

• Stronger revenues expectations vs 2H FY25.

• Expected higher EBITDA margins vs 2H FY25.

• Recent group-wide cost reduction initiatives.

• Potential new customer acquisitions in 2H FY26 on increased presence in key basins. (~$3m potential)

• Additional high volume, but low margin friction reducer sales. (>$5m potential).

• Process Chemistry:

• Targeted efforts on mining could see additional field trials (~$0.5m potential).

Water Technologies:

• Several smaller scale infrastructure projects within the business development scheduled to start in 2H FY26 if tender bids are successful. (~$1.0m potential).

• Continued discussions with major Data Centre developers for solutions to address rapidly growing demand for Water Management services. Potential for initial revenues in 2H FY26.
