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. This is not HPSP's first such distribution this year: the filing discloses the company already transferred 4,410, 86,969 and 4,587 treasury shares under the same compensation program on three separate dates in May and June, and separately retired 1,699,120 treasury shares outright on March 13.
HPSP makes high-pressure hydrogen annealing equipment, a step that repairs defects in the ultrathin layers of leading-edge logic and memory chips. It holds a near-monopoly in that specific process, protected by patents and by customer qualification cycles that take years to complete. Its customers are the largest foundry and memory manufacturers. US investors looking for chokepoints in advanced chipmaking equipment will find one here.
