02PEACEPEACE STUDIO IPO Pricing — 21,500 KRW Bookbuilding Result
PEACEPEACE STUDIO IPO bookbuilding came in at the band-top 21,500 KRW (band was 17,500~20,500 KRW). Institutional demand was strong enough to exceed the band. However, multiple Korean bloggers (Toto, Jidney, Happyll) noted “lockup commitment ratio is on the lower side” — meaning institutions may sell early on listing day, raising day-1 volatility.
OTC reference price (38.co.kr) hovers around ~25,000 KRW, meaning the IPO is roughly -14% discount to OTC. That leaves room for day-1 upside but doesn’t guarantee a “ddatabul” (+300%) outcome.

| Price | Value | Meaning |
|---|---|---|
| Initial band low | 17,500 KRW | Initial valuation |
| Initial band high | 20,500 KRW | Initial valuation |
| Bookbuilding result | 21,500 KRW | Exceeded band — strong demand |
| OTC reference | ~25,000 KRW (est.) | 38 Community |
| IPO vs OTC discount | -14% | Below-OTC pricing |
| Lockup ratio | Reported low | Day-1 volatility risk |
03PEACEPEACE STUDIO IPO Allocation — Equal vs Proportional
Allocation structure is 50% equal + 50% proportional. Equal guarantees 1 share per applicant minimum (if oversubscribed, exactly 1). Proportional allocates based on shares applied — so larger subscriptions favor proportional.
Day-1 oversubscription is around 100x+. Equal-allocation 1 share is virtually certain. For meaningful proportional share count, subscriptions of 5M KRW+ are required. Family-account distribution is the common strategy to multiply equal-allocation shares.

| Subscription | Margin | Equal | Proportional | Estimated total |
|---|---|---|---|---|
| 100,000 KRW | ~50,000 | 1 | 0 | 1 share |
| 500,000 KRW | ~250,000 | 1 | 0~1 | 1~2 shares |
| 1,000,000 KRW | ~500,000 | 1 | 1~2 | 2~3 shares |
| 5,000,000 KRW | ~2.5M | 1 | 5~7 | 6~8 shares |
| 10,000,000 KRW | ~5M | 1 | 10~14 | 11~15 shares |
| 50,000,000 KRW | ~25M | 1 | 50~70 | 51~71 shares |
vTIP — Family-account distribution
Distributing across family-member Mirae Asset accounts can multiply equal-allocation. Each account guarantees 1 share. 5 accounts → 5 shares equal + 1 proportional position concentrated.
04PEACEPEACE STUDIO IPO Listing Day — 5 Scenarios
Korean exchange day-1 price range is -30% to +300%. Maximum upside = “ddatabul” (+300%) — origin of the term. Worst-case = lower limit -30%. Base case from blog consensus: +30% to +100% range. Recent K-fashion IPO comparisons: APR (K-beauty) +350%, Musinsa +120%, Olive Young +90%.

| Scenario | Change | Day-1 close | Read |
|---|---|---|---|
| Lower limit | -30% | 15,050 KRW | Worst — book failure |
| Flat | 0% | 21,500 KRW | Weakness signal |
| Upper limit | +30% | 27,950 KRW | Official 1st cap |
| Double | +100% | 43,000 KRW | 2x debut |
| “Ddatabul” | +300% | 86,000 KRW | Max KRX listing-day cap |
| Base case | +30~100% | 27,950~43,000 KRW | Consensus |
05PEACEPEACE STUDIO Business Structure — Mardi Mercredi Centric
PEACEPEACE STUDIO’s core asset is Mardi Mercredi, the iconic flower-logo Korean designer brand picked by Kim Go-eun. Mardi exploded across Korea, Japan, and Greater China and is one of the top K-fashion global IPs. 2025 Tokyo expansion drove Japan sales growth significantly.
Three axes: fashion/accessories, lifestyle (home/beauty new), and global expansion (Tokyo hub). Major risk: Mardi accounts for 80%+ of revenue — single-brand concentration is the biggest IPO concern. If Mardi trend cools, revenue takes a direct hit.

| Segment | Products | Share | Overseas |
|---|---|---|---|
| Mardi Mercredi | Apparel / shoes / accessories | Main IP (80%+) | Korea / Japan / HK |
| Tokyo base | Shinjuku / Harajuku stores | Global expansion core | 2025 entry |
| Fashion accessories | Celeb collabs / capsules | Mardi+ extension | Online-centric |
| Lifestyle | Home / beauty new biz | Low (new) | Domestic |
| Manufacturing | ODM/OEM outsourced | No vertical integ | — |
| Revenue mix | Mardi 80%+ / Other 20%- | Single-brand risk | — |
06PEACEPEACE STUDIO IPO Day-1 Oversubscription
Day-1 (May 26) closed around 235:1 oversubscription. Started at 12:1 at 10:00, exceeded 50:1 by lunch, then spiked to 200:1+ in the final hour. Standard “back-loaded” pattern for hot Korean IPOs.
Day-2 (May 27) expected to finalize at 500~1,000:1. Recommended to subscribe before 3PM to avoid system delays / submission failures at close.

| Time | Ratio | Applicants (est.) | Note |
|---|---|---|---|
| 10:00 (open) | 12:1 | ~5,000 | Early entrants |
| 12:00 | 48:1 | ~25,000 | Lunch spike |
| 14:00 | 105:1 | ~60,000 | Afternoon rush |
| 15:00 | 142:1 | ~90,000 | 1hr to close |
| 16:00 (close) | 235:1 | ~150,000 | Day-1 total |
| Day-2 est. (16:00) | 500~1,000:1 | 300,000+ | Spike at close |
07Recent K-Fashion / Beauty IPO Post-Listing Comparison
Recent K-fashion / beauty IPO outcomes vary widely. APR (K-beauty) hit +350% day-1 (mega upside). Musinsa hit +120% day-1, now -25%. Olive Young +90% day-1, now +30% (steady). Common cycle: strong day-1 → 3~6 month correction → fundamentals verification.
Mardi parallels APR in brand power but differs in single-brand concentration risk. Short-term ddatabul possible, but long-term stability depends on Tokyo / Greater China expansion success.
