• Reverse Merger Vote Set for August 26

  Shareholders will vote on the reverse merger with Korsana Biosciences, a preclinical Alzheimer's company. If approved, Cyclerion securityholders would own ~1.1% of the combined company, while Korsana securityholders would hold ~98.9%.

• $380M Pre-Closing Financing Secured

  Korsana has commitments for a $380 million private placement from investors including Fairmount, Venrock, and RA Capital, set to close immediately before the merger. This financing gives the combined company a cash runway into 2029.

• Reverse Stock Split and Share Authorization Proposed

  To meet Nasdaq's $4.00 minimum bid price for the combined company's listing, shareholders are asked to approve a reverse stock split at a ratio between 1:2 and 1:10, and to increase authorized common shares from 400M to 700M.

• Cayman Islands Redomestication Planned

  After the merger, the combined company would redomicile from Massachusetts to the Cayman Islands, a move the boards believe will provide greater protection for directors and officers and more flexibility in corporate transactions.

The definitive proxy statement cements the terms of Cyclerion's reverse merger with Korsana Biosciences, a preclinical Alzheimer's company. For Cyclerion—which faces a going-concern warning and holds minimal cash—this deal is a lifeline. Korsana contributes a promising anti-amyloid antibody, KRSA-028, along with a committed $380 million pre-closing financing from top-tier investors. After the merger, Cyclerion shareholders will own just ~1.1% of the combined entity, with Korsana's investors and management taking control. The filing also seeks approval for a reverse stock split to meet Nasdaq's $4 minimum bid price, an authorized share increase, and a Cayman Islands redomestication. The stakes are high: if the merger fails, Cyclerion likely liquidates; if it succeeds, the combined company gains a cash runway into 2029 to advance KRSA-028 through early clinical trials. The vote is set for August 26, 2026.
