Frontier has obtained all necessary regulatory approvals, including conditional approvals from the TSX Venture Exchange, for the offering and listing of the warrants.

Pursuant to the offering, the company entered into an agreement with a syndicate of underwriters led by BMO Capital Markets, under which the underwriters have agreed to buy on a bought deal basis 20 million units at a price of 75 cents per unit for gross proceeds of approximately $15-million. Each unit comprises one common share of the company and one-half of one warrant, with each warrant exercisable to acquire one common share at a price of $1 per warrant share for a period of two years from the closing of the offering. The company granted the underwriters an option, exercisable at the offering price for a period of 30 days following the closing of the offering, to purchase up to an additional 15 per cent of the offering to cover overallotments, if any. Securities sold on exercise of the overallotment option may comprise additional units, common shares, warrants or any combination thereof.

The TSX-V has advised that the warrants are anticipated to be listed for trading on the TSX-V under the symbol FL.WT effective at the market open on April 30, 2026. Each warrant shall entitle the holder thereof to receive one common share of the company at an exercise price of $1, subject to adjustment in certain circumstances, until April 30, 2028.
