THE RUNDOWN

1

TRexBio ($116.7M) and Retension Pharmaceuticals ($45M) both priced and closed this week -- combined $161.7 million -- days after Nvidia-backed Firmus withdrew a roughly $31 billion IPO.

2

Iambic Therapeutics raised its own IPO target from about $100 million to $150 million the same week, a rare upward revision in a cautious market.

3

City Therapeutics just set terms for a roughly $175 million Nasdaq IPO, with trading expected to start Oct. 16 -- the fourth clinical-stage biotech to price in two weeks.

4

Pulse's own tracker shows $184.5 billion in venture funding across 3,399 stories with a $140 million median disclosed round, context for how small these IPOs are next to private-market checks.

The VC Read

Value Add VC analysis

Four small, clinical-stage biotechs pricing in two weeks while a $31 billion infrastructure listing sits withdrawn is the market telling you exactly what it will underwrite right now: near-term binary catalysts at modest valuations, not multi-year, capital-intensive bets. GPs with portfolio companies eyeing 2027 listings should be sizing their IPO targets off City Therapeutics' $175 million, not off pre-correction comps.

Analysis

The pattern across Value Add Pulse's own coverage this month is consistent: small, clinical-stage biotech IPOs keep clearing the market while larger, capital-intensive listings stall. The recent sequence:

  • TRexBio -- closed a $116.7M IPO on Oct. 13
  • Retension Pharmaceuticals -- priced a $45M IPO the same week (combined $161.7M with TRexBio)
  • Firmus -- withdrew a roughly $31B-valuation listing on market-turbulence grounds days earlier
  • Iambic Therapeutics -- raised its own IPO target from about $100M to $150M, a rare upward revision
  • City Therapeutics -- set terms for a roughly $175M Nasdaq IPO (9.7M shares at $17-$19), trading expected to start Oct. 16 under ticker CTY, the fourth clinical-stage biotech to price in roughly two weeks

“The window currently open rewards near-term, binary clinical catalysts at valuations in the hundreds of millions, not thousand-times-revenue infrastructure bets.”

Pulse argued earlier this week that public markets are pricing small, clinical-stage biotech IPOs fine while larger tech and infrastructure listings like Firmus still can't clear; this week's pricings extend that pattern rather than reverse it. Against Pulse's own tracker of $184.5 billion in venture funding across 3,399 stories and a $140 million median disclosed round, these IPOs are modest even by private-market standards -- which is itself the point. The window currently open rewards near-term, binary clinical catalysts at valuations in the hundreds of millions, not thousand-times-revenue infrastructure bets. Whether that window widens heading into 2027 depends on whether a tech or AI-infrastructure name successfully prices before another Firmus-sized withdrawal resets sentiment again.
