MISSISSAUGA, ON / ACCESS Newswire / September 9, 2026 / Microbix Biosystems Inc. (TSX:MBX)(OTCQX:MBXBF)(Microbix®), a life sciences innovator, manufacturer, and exporter, announces that it has completed formal qualification to become a supplier for five in-vitro diagnostics (IVD) manufacturers ("Dx Test-Makers"). Each of these five Dx Test-Makers are considered to be one of the ten largest such companies by revenues, and Microbix is pleased to have successfully completed their supplier audit & quality review processes.
Clearing these detailed and multifaceted supplier qualification processes permits Microbix to supply critical products to these Dx Test-makers, across its antigens, QAPs™, ONBOARDx™ kits, QUANTDx® reference materials, and reagents. In multiple instances, these processes have involved multi-day on-site audits of Microbix's manufacturing, quality control, quality assurance, ISO compliance, and other business systems.
Formal supplier qualification does not guarantee that Microbix will be awarded material contracts from these five Dx Test-Makers. However, it should ensure that opportunities for such business will be more available to Microbix when new projects arise. Additionally, being recognized as a fully-vetted supplier by such large and respected Dx Test-Makers may help Microbix secure business with smaller diagnostics companies that lack the resources to conduct such rigorous supplier qualification processes.
Microbix believes major Dx Test-Makers do not typically commit resources to audit and qualify new suppliers without a clear business reason. While respecting all confidentiality provisions, we can state their actions generally reflect interest in one or more of the following Microbix products or product lines:
Antigens. Purchase of Microbix's native or recombinant antigens to enable the production of tests for assessing prior exposure to, immunity from, or an acute reaction to, an infectious pathogen.
QAPs. Purchase of one or more of Microbix's QAPs patient-sample mimetics as in-kit test-controls to help ensure the accuracy of lab-based or point-of-need infectious-disease tests.
ONBOARDx kits. Purchase of customized kits of Microbix QAPs to assist with qualifying new testing sites and for the initial and periodic training of technicians at those sites.
QUANTDx. Purchase of well-characterized and quantified QUANTDx "reference materials" to assist with new assay development and as QC release standards for the manufacture of assays.
Cameron Groome, CEO & President of Microbix commented, "Focus on ‘Customer Success' is helping us join our team with those of our clients - from initial assay concept through to full commercialization. We're grateful to have been invited to undertake these qualification processes and are pleased to have successfully concluded them. I commend the Microbix team for positively supporting due diligence by five major firms and we certainly aim to secure and disclose new business with one or more of them."
