Q4 has been an extremely busy period for Atomo as it completed its reset for FY 25/26 and readied itself to capitalise on increasing demand emergent for its existing products and commercialisation of new products. The reset included strengthening of the balance sheet, implementing a restructure to increase focus whilst reducing costs, and a Board refresh reducing director numbers, but with two new industry experienced members being appointed. OEM Pascal Supply Business: Atomo’s strategic partner Lumos Diagnostics (ASX: LDX) recently secured a six-year exclusive U.S. distribution agreement for FebriDx® with U.S. company PHASE Scientific. The FebriDx® test, which is delivered to the user in Atomo’s patented Pascal test cassette for improved usability and reliability in point of care settings, has already secured 510k clearance from the US FDA and is well progressed through a CLIA waiver study that is expected to be completed in August. Atomo is the exclusive manufacturer and supplier of the Pascal cassette to Lumos for its FebriDx. Lumos indicated that it expects the agreement with PHASE to generate FebriDx product sales of up to US$316 million (A$486 million) over the six-year term, assuming CLIA waiver is granted and contracted MOQ’s achieved. With this agreement now in place, Atomo anticipates a significant increase in demand for its Pascal cassette from Lumos in the coming years. The company intends to use revenues from OEM Pascal supply to fund commercialisation of its own Pascal diagnostic product pipeline. The Pascal FebriDx® test securing CLIA waiver would also support subsequent Pascal based rapid test applications being progressed through to CLIA waiver in the key US market, including Atomo’s novel Active Syphilis rapid test currently in development. HIV Self-Test Business Growth: Australian HIV Self-Test sales for FY25 totalled $1.4m, compared with total Australian HIV revenue of $575k for the FY24 period, representing growth of 143% year on year. Scale up of public health funded procurement of HIV self-testing in Australia during FY25 reflects growing market for sexual health self-testing as part of public health policy. 1 https://www.kirby.unsw.edu.au/sites/default/files/documents/Annual_Surveillance_Report_2024_STI_1.pdf During the quarter Atomo secured several purchase orders from Australian organisations implementing the Federal Government’s HIV Self-Test programs now being scaled up nationally. The order from NAPWHA, worth approximately $450k, supports ongoing delivery of the national free-to-user HIV Self-Testing program. This second large order from NAPWHA follows an initial order placed in April by Thorne Harbour Health valued at $230k, this order supports the national scale-up of a Federal Government funded vending machine HIV Self Testing Program. Active Syphilis Test – Funded Development and Licencing Agreements now in place In November 2024 Atomo executed a $2.44 million Cooperative Research Centres Projects (CRC-P) grant with the Commonwealth Government. These funds have enabled significant progress to be made towards development of a rapid syphilis test over the last six months. The World Health Organization estimates 8.0 million cases of syphilis globally among individuals aged 15–49 in 2022. In Australia, syphilis cases have tripled over the past decade, with 6,6001 notifications recorded in 2023, and Syphilis is increasingly being recognised by public health agencies globally as an emerging challenge. Current generation rapid Syphilis tests are reactive for antibodies that are present in patients who have previously been treated for past Syphilis infections as well as those with active Syphilis infections. This means that these tests offer very poor specificity in screening programs, materially impacting their clinical utility in point of care settings. This is of particular issue in higher risk cohorts that account for a higher proportion of syphilis infections, and where prior infections are more common. Recent data generated by Atomo’s strategic partner, the Burnet Institute, and recently presented by Burnet at the 2nd Asia Pacific Conference on Point of Care Testing for Infectious Diseases, demonstrates that the Atomo test significantly improved level of specificity in the ability to distinguish between active and prior treated Syphilis during screening. Based on this preliminary data and initial feedback from KOL’s, the company is extremely excited about the clinical advantages of the test and its potential when compared to standard antibody rapid tests currently approved and in use globally. 1 https://www.kirby.unsw.edu.au/sites/default/files/documents/Annual_Surveillance_Report_2024_STI_1.pdf New Product Initiatives: Florey Atomo has successfully completed design work on its Florey clip-in test device, designed specifically to support testing with existing standard cassettes already on the market. This device which utilises Atomo’s existing IP and manufacturing processes, offers a simpler path to adoption as an accessory and has generated interest from a small number of parties engaged during the development. The company is presenting Florey to the market more broadly via the ADLM conference now taking place in the US, where a number of meetings have been scheduled in response to growing interest in the solution. Unlike Pascal, which incorporates the existing test strip directly into the cassette, Florey is designed to accept a standard cassette and allows the test procedure to be completed by the Atomo device. By not having the test directly onboard the Atomo device itself, Florey is designed to be an accessory to approved standard tests. This makes it suitable for adoption by companies with tests already approved and commercialised at scale in market, as the regulatory barriers to adoption of Atomo’s technology are significantly reduced and manufacturing operations for existing tests unaffected. Board Renewal Completed During the period the company underwent a process of board renewal and downsizing:  Directors Ms Deborah Neff, Dr Paul Kasian and Mr John Keith resigned from their positions as Directors of the Company  Dr Cheri Walker remained on the Board, taking up the position of Chair of the Audit and Risk Committee and Mr John Kelly was appointed Interim Chair of the Board.  Mr. Anthony May and Mr Patrick Cook joined the Board as Non-Executive Directors 1 https://www.kirby.unsw.edu.au/sites/default/files/documents/Annual_Surveillance_Report_2024_STI_1.pdf Mr May has held various Director roles across international corporations including Hoechst Germany, Microgenics Corporation USA, Fisher Scientific and Thermo Fisher Scientific. With extensive experience across public and private pathology laboratories, as well as sales and management roles in the IVD supply sector Mr Cook is an experienced Non-Executive Director and Chair with over 20 years of board level experience and over 30 years’ experience in senior executive positions in medical devices & point-of-care diagnostics sectors within multinational and listed biotechnology companies Financials Total revenue & grant income (unaudited) of $1.07m for Q4 FY25, comprising $685k for HIV test sales with the remaining amount from development & other fees, plus grant income of $385k, bringing revenue and grant income for FY25 to ~$4.2m, an increase of 2.7% on FY24. Operating costs for Q4 FY25 were $1.6m (unaudited) compared to equivalent costs for $1.4m in Q4 FY24. Despite a slight increase QoQ, overall YoY operating costs reduced from $7.1m in FY24 to $6.9m in FY25. When taking into account the ~$400k of operating expenses funded directly by the CRC-P for Syphilis development activities, operating expenses improved 24%. Cash receipts during the quarter were ~$1.52m, made up of $1.04m from customer receipts $485k for CRC-P grant payment for active syphilis test. The company also completed a capital raise by way of share placement and Shareholder Purchase Plan (SPP) that resulted in inflows of $1.65m net of costs, seeing Atomo finish the quarter debt-free and with cash on hand of $3.2m. Post year end, a further $926k was collected from the capital raise and an SPP Shortfall placement. In accordance with ASX Listing Rule 4.7C.3, Atomo advises that an amount of $155k was paid during the quarter o Atomo Directors in salary and director’s fees. 1 https://www.kirby.unsw.edu.au/sites/default/files/documents/Annual_Surveillance_Report_2024_STI_1.pdf Key Business Priorities FY26/27: Growing revenues over the next 12 months from existing product channels  HIV Self-Test business across ANZ, Europe and LMIC, ex: Africa  Pascal supply into Lumos’s contract with PHASE, NG Biotech and securing new customers post CLIA waiver of the Pascal FebriDx test in the US Commercialising new Diagnostic Products and Test Devices:  Atomo Active Syphilis Professional and Self-Test variants in advanced development  A pipeline of subsequent applications being planned  Florey introduced as an easy to implement usability upgrade for existing rapid tests Optimising operational pathways and capabilities:  Improving margins through manufacturing efficiencies on higher volumes  Implementing organisational and operational improvements to increase capability, whilst reducing costs and creating greater control For more information, please contact John Kelly Atomo Diagnostics john.kelly@atomodiagnostics.com Phone: +61 401 922 279 This announcement was authorised by the Board of Directors. 1 https://www.kirby.unsw.edu.au/sites/default/files/documents/Annual_Surveillance_Report_2024_STI_1.pdf About Atomo Atomo is an Australian medical device company supplying unique, integrated rapid diagnostic test (RDT) devices to the global diagnostic market.
