Largest Customer Confirms Conversion Timetable & Provides Full-Scale Order

TORONTO, August 1, 2019 – Microbix Biosystems Inc. (TSX: MBX, Microbix®), an innovator of biological products and technologies, provides an update on the conversion of its highest-selling product into bioreactors – that the largest customer for that antigen has confirmed its intended timetable for conversion of its future orders to bioreactor product and has provided its initial full-scale order.

In 2018, Microbix completed a 500% expansion of its bioreactor capacity, moving to six full-scale units from one, along with multiple other production facilities upgrades. Its facilities upgrades were made to house up to eight bioreactors in a dedicated suite. Since that time, multiple customers for that native viral antigen have converted to bioreactor produced product, but its largest customer had been continuing a lengthy program of real-time stability studies and not yet converted. Those stability studies are now completed for some of that customer’s test formats and it has now confirmed how conversions are expected to occur over the course of Microbix’s fiscal 2020, with its first full-scale order for bioreactor product now received.

Due to the long production cycle for this antigen product and the parties’ order scheduling process, it is expected that the first such sales to this customer will be recorded in Q1 of 2020. Completion of the conversion process will mean that Microbix’s production of this largest-selling antigen has moved to its bioreactors. In contrast, over the 12 months ending June 30, 2019, a substantial majority of sales of this antigen were from conventional roller-bottle culturing processes.

Benefits of conversion are expected to be considerable. That antigen has been Microbix’s highest volume and lowest margin product and can comprise as much as half of quarterly sales. Conversion to bioreactor production is expected to enable Microbix to generate a higher and more consistent percentage gross margin. Additionally, transfer of this high volume product into bioreactors liberates capacity to produce more of its other conventionally-made antigen products. Specifically, the full conversion of this product into bioreactors enables Microbix to more than double overall antigen production with little additional capital expenditures. Making such further capacity available will help Microbix keep pace with the demand growth that is expected to be driven by the expanding use of immunoassay medical tests in Asia, where Microbix antigens are being widely incorporated into locally-developed tests seeking approval.

Cameron Groome, CEO and President, commented on this milestone, “We’re delighted about the broadening acceptance of our bioreactor Rubella antigen. All departments have helped with creating and commercializing these new processes. In addition to helping our profitability, the skills we’ve honed are tools to further optimize our business and place us at the cutting edge of antigen production technology.”
