Microbix Completes Multiple Facility Upgrades

Production Capacity Increased to Support Growth Objectives

TORONTO, May 8, 2018 – Microbix Biosystems Inc. (TSX: MBX, Microbix®), an innovator of biological products and technologies, announces the completion of multiple upgrades to its production facility, to improve its revenue capacity and in support of corporate growth objectives.

About Microbix’ Antigens & Quality Products Business

Microbix is a leading independent producer of bacterial and viral antigens for use in medical diagnostics and laboratory quality assessment processes, selling over 100 commercial products to many international diagnostics makers or laboratory accreditation organizations. Antigens enable the detection of circulating immune system antibodies – needed to establish whether a patient has been exposed to a pathogen, has adequate immunity to it, or may have an active infection. The need for antigens is increasing as immunoassay diagnostics are being adopted more broadly, particularly into Asia-Pacific nations. The full product list is available at www.microbix.com.

Facility Upgrades Now Completed

Microbix owns a dedicated production facility in Mississauga, Ontario and has 78 employees. To support the expected growth of antigen demand, Microbix began a program of upgrades to its facility in November, 2017, following a private placement in October, 2017. Its program of upgrades is now substantially completed, with the following tasks having been accomplished:

· Doubling of the power supply	· Expanding the sterile water system
· Expanding the bioreactor suite	· Enhancing media prep capacity & efficiency
· Increasing bioreactor capacity by 500%	· Reallocating glassware prep & cleaning space
· Creation of two new processing rooms	· Transfer of executive support offices offsite
· Addition of two processing ultracentrifuges	· Additions to QC/QA laboratory space
· Addition of four bioprocessing cabinets	· HVAC rebalancing & security enhancements

The largest remaining item is to update and increase autoclave capacity, targeted for later in 2018.

Business Outlook

Microbix is experiencing material growth in demand across its larger-selling antigens. Its intention is to meet this demand by increasing production capacity and via the adoption of new technology, such as its use of bioreactors for production of viral antigens. It thereby seeks to increase overall revenues while also increasing its gross margins – by way of moving production of its largest-selling, but lowest-margin product into a higher-margin bioreactor process and thereby freeing conventional capacity to make more of other, higher-margin antigens. This process is expected to be substantially completed in the latter half of fiscal 2019, and result in enhancements to both revenues and net earnings during fiscal 2019.
