Introduction Parkway is a leading Australian water & wastewater treatment and process technology company primarily operating through two strategically integrated divisions: § Industrial Operations § Process Technologies In addition to providing specialised engineering solutions for industry, Parkway’s Industrial Operations division also provides an inhouse project delivery platform to support the commercialisation of a portfolio of proprietary technologies developed by Parkway’s Process Technologies division. INDUSTRIAL OPERATIONS Parkway’s Industrial Operations are performed through Parkway Process Solutions (PPS) and predominantly focused on the provision of conventional water and wastewater treatment related products and specialty project execution related services. In addition, PPS also provides leading industrial companies including energy, mining and major engineering contractors as well as municipal water authorities, with a range of specialised water infrastructure related engineered solutions. Integrated Project Delivery Capabilities PPS leverages core capabilities across the entire project lifecycle, from early-stage process development and optimisation, through to equipment selection, fabrication, installation and ultimately commissioning, to deliver successful project outcomes. Additional details about the core capabilities, integrated solutions and an extensive list of project references are outlined in the latest PPS Capability Statement1 . Operating Performance Parkway’s focus on complex and high-value infrastructure projects requiring specialised engineering solutions, continues to drive ongoing strategic growth, whilst also expanding inhouse capabilities. As previously disclosed2 , PPS is the key SMP (structural, mechanical & piping) contractor for a major resource recovery project currently under construction. This high-profile project showcases the strategically valuable project delivery capabilities of PPS in delivering complex wastewater treatment related infrastructure at an industrial scale. Despite site activities for the major infrastructure project ramping down in recent months as the project approaches completion, Parkway continued to generate record operating revenue of $7.71 million and strong operating cash flow during the period. Additional details about the financial performance of Parkway are outlined in the Corporate section. Mine Dewatering Contract On 31 August 2026, Parkway announced3 the award of a mine dewatering related contract by a major global mining company. The scope awarded to Parkway predominantly involves the design, engineering, fabrication and supply of industrial scale mine pit dewatering equipment packages (refer Figure 1) for a significant mine rehabilitation related project operated by the global mining company. At peak operating capacity, the Parkway scope will enable the transfer and/or processing of up to 5 million litres per hour (5ML/hr) of wastewater, including highly acidic and complex mine pit wastewater, highlighting the substantial scale of the project. 1 PPS Capability Statement, available at: https://pwnps.com/collections/pps-capability-statement 2 Refer to ASX announcement: https://pwn.investorhub.com/announcements/7021813 3 Refer to ASX announcement: https://investorhub.pwnps.com/announcements/YNNZJx-parkway-awarded-dewatering-contract-by-global-mining-company www.pwnps.com SEPTEMBER 2026 | QUARTERLY REPORT | 3 Figure 1: Mine Dewatering Project – Limited Selection of Project Equipment Packages in Production (i) Fabrication of specialised pump skids (1 of 6). (ii) Transport of pump pontoons for mine pit water. (iii) Fabrication of VSD equipment controls (1 of 2). The project is being delivered through Parkway’s integrated project delivery platform, leveraging Parkway’s established supplier network and involves project management by PPS-Melbourne, fabrication and containerisation by PPS subsidiary Tankweld and local project support by PPS-Darwin. The scale of the dewatering project has incrementally increased to approximately $2.1 million with the contracted scope expected to be finalised in the December quarter, demonstrating the professional and highly efficient project delivery capabilities of Parkway. As part of current discussions to evaluate opportunities to expand the longer-term dewatering related scope, Parkway is also exploring the potential to provide an integrated solution for the acidic and metalliferous drainage (AMD) wastewater produced by the mine, based on proprietary Parkway technologies. Additional details are outlined in the Acid & Metalliferous Drainage (AMD) Opportunities section, under Process Technologies. Business Development & Outlook In addition to the mine dewatering project outlined above, PPS continues to experience significant growth by systematically securing new business from diverse clients, for the provision of specialised water & wastewater treatment related products, services and solutions. During the period, PPS expanded its accredited vendor status with several major organisations, which continues to build a strong growth platform and provide increased confidence in the medium-term revenue outlook. PROCESS TECHNOLOGIES Parkway’s Process Technologies related activities are performed through Parkway Process Technologies (PPT) and predominantly focused on innovative process technology related R&D, process development, evaluation and optimisation, as well as a range of technology scale-up and commercialisation related activities. Technology Development Through PPT, Parkway continues to build a portfolio of proprietary technologies, capable of providing highly integrated process solutions, for a range of complex wastewater and industrial process streams traditionally considered difficult to treat. PPT has developed innovative applications for these technologies, including in the processing and treatment of challenging industrial wastewater streams, particularly for large scale industrial, oil & gas, mining and mineral processing related operations. PPT Priorities The development and commercialisation of a portfolio of proprietary process technologies remains a priority for Parkway, with a range of ongoing activities focused on realising the substantial advantages of the PPT technology portfolio. As a near term priority, Parkway is progressing the commercialisation of these technologies in the context of coal seam gas (CSG) related applications through Queensland Brine Solutions (QBS). Given these technologies have broader applications beyond CSG derived brine processing, Parkway is also concurrently pursuing additional development opportunities with established partners, particularly given Parkway’s growing project delivery capabilities. Further details are provided in the Technology Commercialisation – Industrial section, below. www.pwnps.com SEPTEMBER 2026 | QUARTERLY REPORT | 4 Technology Commercialisation – Queensland Brine Solutions (QBS) Background Since the large-scale development of the CSG industry in Queensland in 2010 and the corresponding establishment and subsequent transition to the export of liquified natural gas (LNG) commencing in 2015, the CSG industry has been a significant part of the Queensland economy. Over the life of currently operating CSG projects in Queensland, an estimated 6 million tonnes of waste salts are forecast to be produced by these projects. A significant proportion of these salts have already been produced, in the form of waste brine and are currently being stored in regulated waste brine storage ponds, awaiting a viable long-term disposal solution. The disposal of waste brine and salts through salt encapsulation as contemplated by the CSG industry, present extensive environmental risks and challenges and remains deeply unpopular, with significant opposition from many stakeholders. Developing an Integrated Solution Following more than a decade of systematic process development, Parkway has developed a roadmap for providing an industry-wide solution for the waste brine and salt related challenges facing the Queensland CSG industry. Parkway intends to lead the development of strategic brine processing related infrastructure, by leveraging its proprietary technologies to address significant industry challenges (provision of liquid waste management services), whilst concurrently creating significant value through the production of industrial chemicals. An overview of the integrated brine management solution being developed by QBS through the QBMC project is outlined in Figure 2. It should be noted that the QBMC’s capacity to process non-CSG sources of brine, is highly attractive given the significant challenges associated with brine disposal by industry. Figure 2: Queensland Brine Solutions (QBS) – QBMC Integrated Brine Management Solution QBMC Scope & Roadmap Whilst the primary long-term focus of the QBMC is to process CSG derived brines, as outlined in Figure 2, the QBMC development configuration will also enable the processing of other industrial and municipal waste brines. In addition to the extensive testwork already performed in relation to a range of CSG derived brines, Parkway has also been actively testing and evaluating other problematic waste brines available in the general proximity of the planned QBMC. The strategy of ensuring QBMC is capable of processing a diverse range of brines, provides Parkway with maximum operational flexibility as well as broader partnering options to pursue the most optimal development roadmap. To accelerate the path-to-market, Parkway is at the advanced stages of planning a Commercial Demonstration Project (CDP, Stage 0) for the QBMC. In addition to processing a wide range of waste brines and generating early revenues, the QBMC-CDP is intended to provide engineering data to support a final investment decision (FID) for full-scale development of Stage 1. www.pwnps.com SEPTEMBER 2026 | QUARTERLY REPORT | 5 QBMC Approvals On 20 August 2026, Parkway announced the Western Downs Regional Council (WDRC) approved the DA for the QBMC. The approved DA encompasses additional approvals from the Queensland Government State Assessment and Referral Agency (SARA), including key Environmental Authority (EA), as well as state-controlled road access permit. These key approvals support the accelerated development of QBMC, as the scope of these approvals covers both: § QBMC-CDP (Stage 0, Commercial Demonstration Project) § In addition to processing a wide range of waste brines, the QBMC-CDP is intended to provide engineering data to underpin a final investment decision (FID) for full-scale commercial development of Stage 1. The nominal capacity of QBMC-CDP is anticipated to be 1/10th scale of the first commercial stage, Stage 1. § QBMC-Commercial (Stage 1, strong financial metrics4 , NPV >$700 million, IRR >30%) § Stage 1 represents the first full-scale commercial development with a nominal processing capacity of ~75,000 tonnes of contained salts, in waste brine, annually. § Whilst Stage 1 represents a nationally significant scale of liquid waste management and chemical production infrastructure, the QBMC Master Plan involves the potential for staged development of up to 4 stages, a capacity that could notionally treat all the lifecycle waste brines produced by the coal seam gas (CSG) industry in Queensland5 . Strategic Implications As a result of securing key approvals, the QBMC will be the only regulated waste facility (RWF): § permitted to process CSG derived waste brine and salts, and § capable of converting the CSG derived waste brine and salts into valuable industrial chemicals, a beneficial use pathway that is required by the existing regulatory framework (see below). QBS is in active discussions with a range of stakeholders, including from industry in relation to how QBMC can best provide solutions for enduring waste brine challenges, including for the CSG industry. Regulatory Framework Report QBS recently published6 a Regulatory Framework Report outlining the policy and regulatory frameworks that apply to the production, storage and disposal of CSG derived brines in Queensland. Key Findings § Saline brine presents long-term challenges because salt is difficult to remediate once released and capable of creating enduring rehabilitation, residual risk and stewardship obligations. § Queensland’s regulatory and policy framework prioritises prevention of environmental harm, resource recovery from waste through beneficial uses and the minimisation of waste disposal. § Reliance on interim brine dams and potential disposal via salt encapsulation facilities does not resolve the underlying long-term liability associated with waste brine and salts. § QBMC represents a credible and timely opportunity to shift Queensland’s CSG brine management from indefinite storage and planned disposal towards beneficial use outcomes. § Through QBMC, beneficial use can now be considered a practical and credible pathway. § Regulatory settings require operators to consider beneficial use, before reliance on lower-order brine storage or disposal pathways likely to require stronger, evidence-based justification. 4 Indicative financial metrics, including basis outlined in the 2025 AGM Presentation: https://investorhub.pwnps.com/announcements/7280044 5 Based on annual processing capacity of 75ktpa of contained salts in waste brine, across each of Stages 1 – 4, over nominal 20-year project life, for each stage. The cumulative processing capacity would result in the processing of approximately 6 million tonnes of contained salts. 6 The Regulatory Framework Report is available at the QBS website, https://www.qldbs.com. www.pwnps.com SEPTEMBER 2026 | QUARTERLY REPORT | 6 Technology Commercialisation – Industrial In parallel with the commercialisation of process technologies being advanced through QBS, Parkway is also progressing the commercialisation of PPT’s proprietary flowsheets, with applications in industrial, mining and other major industries. Modular Process Equipment Systems Parkway is leveraging its core process technology related capabilities to develop a core product range focused on complex brine, i) pre-treatment, ii) concentration, iii) crystallisation and iv) chemical synthesis. These modular process equipment (product) packages will support the rapid development of Parkway projects including (but not limited to) the QBMC project, as well as provide an efficient go- to-market capability to offer these packaged equipment systems to third parties. Parkway is collaborating with multiple leading global equipment (OEM) and engineering (EPC) contractors, to develop this state-of-the-art offering based on pre-engineered and qualified systems. Industrial Brine Management Facilities The modular process equipment systems developed by Parkway for core brine processing flowsheets including for QBMC are also applicable to a broader range of industrial waste brine related applications. Parkway is currently collaborating with several interstate operators of major industrial scale liquid waste management facilities, to evaluate the potential to co-locate industrial brine management facilities based on PPT technologies. These established liquid waste facilities generally face existing onsite waste brine challenges, providing attractive co-development opportunities for Parkway. The most attractive partnership opportunities being advanced by Parkway, involve the establishment of dedicated joint ventures to address existing (onsite) brine challenges, as well as provide regional brine management solutions to industry. The proposed industrial brine management facilities would be based on PPT technologies and leverage the modular process equipment systems, developed by Parkway. Whilst the proposed brine management facilities are not intended to be a substitute for the strategically important QBMC, the proposed facilities provide Parkway with an opportunity to accelerate project development and technology roll-out, given they could potentially be developed on existing (brownfield) project sites with significant existing infrastructure in place. Parkway Hitachi – Ultra-High Brine Concentration Systems As previously announced7 , Parkway is collaborating with Hitachi to develop state-of-the-art ultra-high brine concentration systems. The initial focus of the collaboration is the development of standardised modular brine concentration systems (PH-UHBCS) intended to provide compact, modularised, high- performance and energy-efficient brine concentration capabilities. During the period, significant progress was made in advancing the engineering design, in preparation for production of the first system to commence in the near-term. Parkway is in discussions with several parties regarding options for offsite brine concentration with PH-UHBCS, including for the co-development opportunities outlined above. Acid & Metalliferous Drainage (AMD) Opportunities With the support of the modular process equipment systems, the proprietary flowsheets developed by Parkway have applications in addressing AMD mine rehabilitation related challenges prevalent across the mining industry. As outlined above, Parkway is exploring potential opportunities to provide a technology-based solution (PPT flowsheet) to address AMD related challenges for the project where Parkway is currently providing a critical mine dewatering solution. One of the potential development concepts being assessed involves onsite mine pit water pre-treatment and concentration, before the concentrate is transported to a regional brine processing hub being evaluated by Parkway. This project would support broader mine rehabilitation related objectives being pursued by the Northern Territory government, as well as potentially support the development of greenfield mining projects and the sustainable expansion of existing operating mines in the region. 7 Refer to 19 May 2026 ASX announcement, available at Parkway Investor Hub: https://investorhub.pwnps.com/announcements/7543378 www.pwnps.com SEPTEMBER 2026 | QUARTERLY REPORT | 7 CORPORATE Financial Summary Parkway generated record group operating revenues of approximately $7.71 million during the period, a 114% increase from the prior corresponding period ($3.61 million, Q1-FY26).
