Bigwave Robotics fixes its price a day before Brills closes its institutional book
Five Korean retail subscription books open across four days from the 14th. Bigwave Robotics sets its final price on the 14th, one day before Brills stops taking institutional orders for a second robot automation deal.

What happened
- Bigwave Robotics adjusted its offering structure and price range several times while preparing to list, and its final price is due on the 14th from a 15,000 to 18,000 won band.
- Brills, also a robot automation specialist, closes institutional bookbuilding by the 15th and takes retail orders on the 17th and 18th at 16,500 to 19,500 won, with IBK Investment & Securities as lead.
- Duksan Neolux Corps is the first company to clear Korea Exchange listing review since the dual-listing restriction, qualifying for exemption with the consent of parent Duksan Hi-Metal's shareholders.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- decision Institutions sizing Brills orders can wait a day and price off a comparable robot automation deal, so Bigwave carries the cost of going first.
- constraint With three books open on the 16th and three on the 17th, a retail investor choosing one subscription is declining two others in the same session.
- precedent The parent-shareholder-consent exemption now has a working example, giving other Korean subsidiaries a route through review that the dual-listing policy otherwise closes.
- exposure The record carries no offering sizes, so the only public read on demand this week is where each price lands inside its band.
Bigwave Robotics announces its final offering price on the 14th, and Brills keeps its institutional book open until the 15th [5][11][19]. Fund managers writing orders for Brills get one number their Bigwave counterparts did not have. Brills is asking 16,500 to 19,500 won a share [11]. That floor sits 10 percent above Bigwave's 15,000 and that ceiling 8.3 percent above Bigwave's 18,000 [16].
Only one price in the week is settled. Wiseplanet, a media commerce firm managed by Daishin Securities, priced at 12,000 won, the top of a 10,000 to 12,000 indicative range and 20 percent above the floor [2][15]. Wiseplanet sells filtered showerheads under Dr. PL, bedding under Nujam and cosmetics under Irenol, and handles planning through to sales itself [3].
The retail calendar puts three subscriptions open on the 16th: Bigwave, Global Technology and Duksan Neolux Corps. Three are open again on the 17th: Global Technology, Duksan Neolux and Brills [17]. Two of the five retail deals are robot automation companies [21], and they never share a retail day: Bigwave takes orders on the 15th and 16th, Brills on the 17th and 18th [18]. Sedaily reports that how investor demand splits between the two is drawing attention [12].
Duksan Neolux Corps makes satellite navigation devices and anti-jamming equipment that blocks radio interference [8]. It is the first company to clear Korea Exchange listing review since the government introduced a policy restricting, in principle, the dual listing of subsidiaries. As a subsidiary of Duksan Hi-Metal, it met the exemption requirements by securing the consent of its parent's shareholders [9]. Its institutional book runs through the 14th and its price is set on the 15th, the same day Global Technology sets its own from a 13,000 to 15,000 range [10][7][22].
In my view this is one price test with four offerings attached to it. Bigwave adjusted its offering structure and price range several times while preparing to list [5], and its band is 20 percent wide from floor to top [20]. A print at 18,000 says the reworking found the level. A print at 15,000 says institutions are still not there. The counter-read is that Wiseplanet cleared at the top of its band in the same week [2], which argues the crowded calendar is not by itself pushing prices down. The report does not include offering sizes or share counts for any of the seven companies [23], so the won amount retail investors are being asked to fund cannot be computed from it.
The queue runs past the 18th. Gincostec, moving from Konex to the KOSDAQ with cosmetics materials and finished products, has proposed 19,500 to 23,500 won with Hana Securities as lead [13]. Semiconductor equipment maker Melcon has proposed 10,700 to 12,300 won with Daishin Securities [14], and both take institutional orders from the 16th to the 22nd before retail subscriptions next month.
What to watch
- Bigwave Robotics's final price on the 14th against its 15,000 to 18,000 won band.
- Subscription multiples for the two robot books once Brills's retail window closes on the 18th.
- Whether other subsidiaries use the parent-shareholder-consent route that got Duksan Neolux through review.
