# OSR Holdings completes Woori IO acquisition; legacy shareholders lock $10/share exchange, reviews subsidiary combination

## Summary
- Acquisition of Woori IO closed Jan 26, 2026; WORIO becomes indirect wholly-owned subsidiary via share exchange (84,338 OSRK shares for 88,891 WORIO shares).
- Legacy Woori IO shareholders reaffirmed three-year equity alignment; they may exchange OSRK equity only at $10.00/share, preventing near-term dilution.
- OSRH initiates strategic review of combining Woori IO and RMC into a new medical device company; potential standalone IPO in Korea under evaluation.
- No OSRH common stock issued in transaction; acquisition funded through subsidiary equity interests.
