The Japan-to-Nasdaq micro-cap market is not underwritten by the bulge bracket. It is run by a short list of retail-facing bookrunners, and the concentration is visible directly in the data.
Who leads these deals
Among the tracked Listed names, EF Hutton is bookrunner of record on the most — LRE, SBC, LGCB and the de-SPAC AWIN. Kingswood leads three: TOYO, CTW and LFS. Boustead sits behind a cluster of the earlier deals (SYT, PXDT, MTRS, ZRSP, LBRJ) — several of which are now delisted, abandoned or terminated. The rest of the field — Prime Number Capital, AGP, Maxim, Univest, Spartan, Network1, Tiger Brokers — each carry one or two.
The cross-border micro-cap IPO has a settled template. A bookrunner who has run it once executes the next far more cheaply — which is exactly why the field collapses to a few names.
What the concentration buys, and what it costs
For an issuer, a proven bookrunner means the process is a path already walked: the comment-letter cycle, the auditor and counsel pairings, the roadshow to a known retail base. That is real value on a first US listing.
But the same names recur on the worst outcomes, too. WRNT (−88.8%, Prime Number Capital) and the EF Hutton-led LGCB (−99.3%) sit at the bottom of the return table. A bookrunner's presence does not underwrite the aftermarket; it underwrites the *closing*. The two are routinely confused by first-time issuers.
The signal in a change of bookrunner
One data point worth watching is when the bookrunner changes between filings. GTSG's syndicate shifted (Loop Capital appears in the record); Boustead engagements on several names are marked terminated. A bookrunner leaving a deal mid-process is rarely disclosed as such, but it tends to precede either a re-priced, smaller offering or a stall. Reading the syndicate across successive amendments is one of the few early signals a public filer gives.
The league table on this site aggregates every deal by bookrunner, so the pattern — a handful of firms, repeated pairings, and a strike rate that has more to do with the market than the manager — is visible as first-order data rather than anecdote.
