Actio Biosciences Acquisition

Actio Biosciences was acquired by Jazz Pharmaceuticals for $1.3B on 10 August 2026.

Before the acquisition Actio Biosciences had raised $121M across 2 funding rounds.

Jazz Pharmaceuticals agreed on August 10, 2026 to acquire privately held Actio Biosciences for $820 million upfront and up to $500 million in contingent consideration, implying a total transaction value of up to $1.32 billion. The structure includes regulatory approval and sales-related milestone payments, and the deal was unanimously approved by both boards with closing expected in the fourth quarter of 2026. Jazz plans to fund the acquisition with cash on hand and existing financing facilities. The strategic rationale is Jazz’s expansion of its rare epilepsy portfolio through Actio’s experimental treatment for a rare inherited form of epilepsy that currently has no approved therapies. The acquisition is positioned as a pipeline-building move in rare neurology, with milestone payments tied to development and commercial progress. Actio Biosciences is a privately held biotechnology company focused on rare disease programs, including epilepsy. The company’s shareholders are set to receive the upfront payment plus potential milestone-based contingent consideration under the merger agreement.
