Further Capital to Assist with Increasing Capacity and Efficiency

MISSISSAUGA, CANADA, October 27, 2021 – Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator and exporter, announces that it has received C$ 2.7 million from the partial exercise of two series of expiring share purchase warrants.

The first series of such warrants were issued in connection with a private placement undertaken in October, 2015, and had an exercise price of C$ 0.55 and a five-year term. The original term of these warrants was extended by one year, as announced by Microbix on September 17, 2020. A total of 1,200,000 of these warrants have been exercised, representing 80% of the total outstanding warrants and providing C$ 660,000 of further equity capital to Microbix.

The second series of such warrants were issued in connection with a private placement undertaken in October, 2017, and had an exercise price of C$ 0.36 and a three-year term. The original term of these warrants was extended by one year, as announced by Microbix on September 17, 2020. A total of 5,658,819 of these warrants have been exercised, representing 97% of the total outstanding warrants and providing C$ 2,037,175 of further equity capital to Microbix.

The total C$ 2,697,175 received from the exercise of these warrants more than offsets the funds used for the early repayment of the C $1.3 million 9% debenture made on October 1, 2021. As of today, Microbix has over C$ 11 million in cash on its balance sheet, along with an undrawn line of credit for up to C$2.0 million. Some of the available funds are being used to drive increasing production capacity for QAPs™ and DxTM™, and for increasing the capacity and efficiency of all operations – to improve margins and earnings.

A total of 375,002 of the 2017 warrants were exercised by Insiders, for whom the term extension was approved by shareholders at Microbix’s Annual General Meeting on March 30, 2021. After addition of all new shares resulting from warrant exercises, Microbix has 129,967,086 common shares outstanding.

Cameron Groome, CEO and President of Microbix, stated, “We greatly appreciate the confidence that our shareholders are demonstrating by exercising their expiring warrants to purchase common shares. We commit to appropriately deploy the additional equity capital that they are committing. Such new equity capital will be used to create further value for our shareholders by helping enable Microbix to support much greater sales and achieve better gross margins and net earnings.”

Jim Currie, CFO of Microbix, also commented, “With these warrant exercises and our recent debenture repayment, Microbix now has a debt-to-equity ratio of less than 0.5 and a current ratio of over 4.0. This financial strength helps demonstrate to prospective customers that we are a reliable long-term partner and should thereby accelerate the growth of our business. Among other matters, our available funds and ongoing positive cash flow are being used to add new product development labs and manufacturing spaces, and to upgrade quality management and enterprise resource planning systems.”
