MBX Microbix Biosystems Inc

Microbix Biosystems Inc. (TSX: MBX, OTCQB: MBXBF, Microbix®), a life sciences innovator, manufacturer, and exporter, announces it has applied to the TSX to extend the term of an aggregate of 5,750,000 common share purchase warrants (“Warrants”) which were issued in connection with Microbix’s May 19, 2021 prospectus and private placement financings.

The Warrants now entitle holders to purchase common shares of Microbix at a price of $0.80 until May 19, 2023. Microbix has applied to the TSX to extend the term of the Warrants by one year. The Warrant extension is approved by the Company’s board of directors but remains subject to TSX acceptance. The TSX Company Manual requires disclosure of warrant amendments to be made by press release at least ten (10) business days prior to the effective date. Accordingly, the term extensions will not be effective until May 29, 2023. Warrant holders will therefore not be permitted to exercise warrants between May 19, 2023 and May 29, 2023. All other Warrant terms will remain unchanged.

The Warrant series for which term extensions are being sought are 87.9% held by parties that are arm’s length to Microbix. Term extensions for the 12.1% of Warrants held by Microbix insiders will be contingent on disinterested shareholder approval, and insiders will not be permitted to exercise such Warrants unless and until such approval is obtained. Microbix proposes to include the warrant extension in respect of insiders as an item of business at the Company’s next shareholder meeting. All proposed Warrant term extensions are subject to TSX approval.

The decision to seek extension of the term of these Warrants was undertaken by the board of directors. After analysis, the board concluded that additional capital could be put to effective use by Microbix and that improving the prospect of the exercise of these Warrants at $0.80 could help provide additional capital without the discounts or transactional costs associated with new private placements or public offerings of equity.

The Toronto Stock Exchange does not accept responsibility for the adequacy or accuracy of this release.
