Karyopharm plans Ayrmid merger through Chapter 11 restructuring with $55 million financing commitment
Karyopharm Therapeutics has announced a proposed merger with Ayrmid through a court-supervised Chapter 11 restructuring process, supported by a $55 million additional financing commitment.
The restructuring support agreement announced on 2 November 2026 follows Karyopharm's voluntary US bankruptcy filings and outlines a potential combination with Ayrmid under a reorganisation plan that remains subject to court oversight and competing bids.
The additional $55 million commitment is intended to support operations during restructuring rather than fund an acquisition purchase price, with the proposed merger expected to close in the first quarter of 2027 if the required approvals and conditions are satisfied.
