Antibe Closes Previously Announced Strategic Sale of Citagenix Subsidiary

Antibe Therapeutics Inc. (TSX: ATE, OTCQX: ATBPF), a clinical-stage company leveraging its hydrogen sulfide platform to develop next-generation safer therapies to target inflammation, is pleased to announce the closing of the sale of its Citagenix Inc. subsidiary to HANSAmed Limited (“HANSAmed”), a leading Canadian distributor of pharmaceuticals and medical devices to dental professionals.

“With the closing of this deal, we’ve evolved into a pure-play drug developer advancing a non-opioid acute pain therapy with best-in-class potential,” commented Scott Curtis, Antibe’s Chief Operating Officer. “Importantly, it provides non-dilutive funding for our pipeline and fortifies our already strong balance sheet. And of course, we wish the Citagenix and HANSAmed team the very best.”

First announced on May 2, 2022, the $6.5 million transaction involves a guaranteed $3.5 million, divided into four equal payments over three years, with the remaining $3 million subject to Citagenix achieving sales milestones in that period. In accordance with the agreement, the Company has received proceeds totaling approximately $2.5 million, comprising the first of the four guaranteed payments of $875,000, an adjustment of approximately $520,000 in estimated excess working capital and $1.14 million from the repurchase by Citagenix of preferred shares previously issued to the Company.
