SK Hynix Union Rejects 60% Stock Bonus Deal by 25 Votes, Renegotiation Risk Rises

The Quick Take

• SK Hynix's tentative wage agreement was rejected by 50.08% of union members — just 25 votes decided the outcome
• The core dispute: the proposal to pay 60% of profit-sharing bonuses (PS) in company stock rather than cash
• Of 16,038 eligible members, 15,045 voted (93.81% turnout), reflecting exceptional stakes for both parties
• Full renegotiation expected if the technical staff union also rejects, raising wage cost uncertainty in HBM peak season

SK Hynix's labor dispute over performance bonus payment structure underscores the growing tension between Korean conglomerates and workforces over equity-based compensation. The rejected agreement proposed a 6.3% wage increase and payment of 60% of profit-sharing bonuses in company stock rather than cash — a proposal that divided nearly 15,045 voters almost exactly in half, with only 25 ballots separating approval from rejection. The 93.81% turnout reflects the exceptional importance workers attach to compensation structure, particularly as SK Hynix has reported record profits driven by the global AI-driven memory chip supercycle.

For SK Hynix investors, the rejected deal introduces near-term renegotiation risk and potential labor action that could disrupt production when memory chip demand — particularly HBM for AI servers — remains elevated. The technical-office staff union vote was still pending at the time of reporting; if both unions reject, full renegotiation begins, implying potential wage cost overruns. Samsung Electronics is watching closely: SK Hynix's compensation settlement benchmark historically influences Samsung's own union negotiations, making the outcome a sector-wide wage signal for Korean semiconductor majors.

Investors should monitor the technical staff union vote result, which determines whether SK Hynix enters full renegotiation or can settle components separately. If renegotiation extends into Q4, it could coincide with peak HBM delivery season for Nvidia and other AI chipmakers, adding execution risk to an already tight supply chain. The critical macro variable is Korean won strength versus USD — SK Hynix pays wages in KRW while HBM revenues are USD-denominated, meaning a stronger KRW amplifies the real cost of any wage concession the company ultimately agrees to.
