Analysis · APTOF · Life Sciences
This filing provides the definitive terms for the previously announced acquisition of Aptose Biosciences by HS North America Ltd., a subsidiary of Hanmi Pharmaceutical Co. Ltd. The arrangement agreement was amended and restated on February 23, 2026, to extend the outside date for completion. The Board, based on a unanimous recommendation from its Transaction Committee and a fairness opinion from Locust Walk Securities, LLC, unanimously recommends shareholders approve the C$2.41 per share cash offer. The transaction is critical for Aptose, as the company faces a significant likelihood of insolvency if the arrangement is not completed, potentially leading to CCAA proceedings where shareholders may receive no consideration. The offer price represents a 28% premium to the 30-day volume-weighted average price.
