New Customers, More Products, and Expanding Capacity

TORONTO, February 5, 2019 – Microbix Biosystems Inc. (TSX: MBX, Microbix®), an innovator of biological products and technologies, provides an update on the expansion of its quality assessment product lines, announcing the addition of new customers, more products, and steps to expand its production capacity.

Microbix’s quality assessment products (QAPs™) are stabilized and inactivated pathogen samples. QAPs are used by proficiency organizations, diagnostic test developers, researchers and clinical laboratories and are now being manufactured under ISO 13485. Microbix has long offered a range of such products to proficiency organizations for use in their clinical laboratory certification programs (its PTDx™ line). In 2018, Microbix added the PROCEEDx™ line to its quality assessment offerings, for use in research, assay development, validation/verification of instruments, troubleshooting, and operator training.

PROCEEDx™ products are now being sold to multiple diagnostics companies, which will ship these Microbix-branded QAPs to their customers as a part of their new instrument sales or for use in their R&D and internal QC. Such shipments are the first time that Microbix’s name will be visible to end-users in the diagnostics market – a strategic milestone for our company. Development of further PROCEEDx™ brand QAPs is ongoing in collaboration with multiple leading diagnostics companies. Microbix believes such engagement substantiates its QAPs opportunities.

In order to effectively support its QAPs programs, Microbix is also pleased to announce that it has leased additional office, production, and warehousing space at 235 Watline Avenue in Mississauga. The newly-leased space will provide a further 10,300 square feet of space adjacent to its fully-owned 14,000 square foot production site at 265 Watline Avenue. When it takes occupancy this spring, Microbix will cede the office space it currently rents at 211 Watline Avenue and consolidate all its operations across the two neighboring buildings. It is expected that the new site will provide adequate space for filling, labeling and testing of its QAPs products at greatly-expanded volumes.

Cameron Groome, CEO and President of Microbix, provided further perspective. “Our quality business builds from the capabilities we developed to provide native antigens for many leading immunoassay makers. Supporting both immunoassays and molecular diagnostics, we expect our QAPs sales to grow in absolute terms and as a proportion of our total sales. In addition, we are pursuing new intellectual property to protect our product innovations in this field. We look forward to further reporting upon the sales growth of the QAPs product lines and their related value creation.
