HPSP (KOSDAQ:403870) approved distributing up to 51,517 common treasury shares — about 0.1% of its 82,300,000 shares outstanding — to 37 employees and officers between August 7 and October 30, 2026, satisfying vested stock options and restricted stock units. The reference price is the prior day's close of ₩35,800, for a maximum value of about ₩1.84 billion; the filing notes the final count may shrink if some recipients leave the company or miss vesting conditions before the period ends.
