Hanmi Pharm Distributes ₩3.9 Billion of Treasury Shares to Staff, More Than Planned

Hanmi Pharmaceutical (KRX:128940) disposed of 11,180 common treasury shares to employees and officers on August 4 at the prior day's close of ₩345,500, for a total of ₩3.86 billion, transferred directly into recipients' brokerage accounts via Shinhan Investment. The filing's own reconciliation table flags the outcome as "inconsistent" with what the company originally scheduled: 10,402 shares planned versus 11,180 actually distributed, a gap the filing attributes to share-price movement and performance-evaluation results between the board's disposal decision and the actual settlement date. Separately, the filing notes Hanmi holds another 110,700 treasury shares acquired for a specific statutory purpose that are excluded from this table entirely.

128940 Company Profile

Hanmi Pharmaceutical sells prescription drugs in Korea while developing a pipeline in obesity, metabolic disease, and rare conditions, several assets of which it has licensed to Western partners. Its long-acting drug platform, which extends how long a dose stays effective, is the basis of most of those deals. A public fight for control among the founding family has drawn attention from the English-language business press. For US investors it is a Korean company competing in the same obesity-drug field as Novo Nordisk and Eli Lilly.
