MBX Microbix Biosystems Inc

Microbix Biosystems Inc. (TSX: MBX, OTCQX: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces that it has received C$ 2.4 million in new equity capital from the partial exercise of expiring share purchase warrants.

The warrants were issued in connection with a private placement undertaken in January, 2020, and had an exercise price of C$ 0.36 and a five-year term (the “2020 Warrants”). Originally, 12,321,000 of the 2020 Warrants were issued and 8,881,564 of the 2020 Warrants remained unexercised at September 30, 2024. A total of 6,703,314 of those remaining 2020 Warrants have now been exercised, representing 75.5% of the remaining warrants and providing C$ 2.4 million of additional equity capital to Microbix.

Microbix intends to use this additional capital to broaden its product development capabilities, to expand its manufacturing capacity, and to make more improvements to the efficiency of its operations. A portion of the proceeds may also be used to reduce debt or, when judged to be appropriate, to fund additional share repurchases under Microbix’s previously-disclosed Normal-Course Issuer Bid (“NCIB”).

A total of 1,450,000 of the remaining 2020 Warrants were exercised by Insiders. After addition of all new shares resulting from 2020 Warrant exercises, Microbix has 142,326,164 common shares outstanding. There are no further Microbix warrants outstanding following the expiry of this series. Microbix’s cash and equivalents balance stands at over C$ 15 million after the exercise of these last 2020 Warrants.

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 will 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 realize still greater sales, achieve better gross margins, and attain higher net earnings.”

Jim Currie, CFO of Microbix, also commented, “With these warrant exercises, Microbix now has a current ratio of over 7.0 times and a debt-to-equity ratio of approximately 0.30. This financial strength helps demonstrate to current and 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 capabilities, manufacturing capacity and sophistication, and to implement optimal use of our eQMS and ERP systems.”
