The paper gain on 300,000 shares sitting above the strike price — ₩765.6M — disappears unless they are exercised by the deadline. Among the options whose lockup has ended, this is the part whose timing is pinned down.

Options the share price has risen past gain a reason to be exercised and sold once the lockup ends. Filings do not show what has already been exercised or forfeited, so these figures are on a cumulative grants basis and the shares actually outstanding may be fewer.

Share price vs. strike price

A strike price is fixed on the grant date; only the share price moves. Where the price line crosses a dashed line is when that block of options first had a reason to be exercised.

Recipients granted less than 10 in 10,000 of total shares issued have their names withheld under the disclosure rules; they cannot be split apart, so they are grouped into one row. Rows that pack several people onto one line, such as “OOO and 6 others”, are grouped there too, with the headcount read from that text — the split between them is never disclosed, so “my share” can only be prefilled with the per-person average. Filings carry no employee number or year of birth, so people with the same name are added together as one. “Exercisable” counts shares whose lockup has already ended, and any paper gain accrues to the employees holding the options.

Every figure here is parsed mechanically from the original DART filing (document.xml). “Exercise starts (estimated)” means the filing did not state an exercise period, so the date is the grant date plus two years under Article 340-2(4) of the Korean Commercial Act and may differ from the actual terms. Always read the original filing before making any decision.
