S-1 Filings Are Piling Up Faster Than Pricings

The SEC logged 12 new S-1 filings and 11 S-1/A or 424B4 amendments in a single late-September window, while only two names -- ADARx and Oura -- actually priced, a widening gap between filing volume and real liquidity.

THE RUNDOWN

1

The SEC logged 12 fresh S-1 filings and 11 S-1/A or 424B4 pricing amendments in a single late-September window, but only two names, ADARx and Oura, actually converted to a priced, trading listing in that same stretch.

2

A filing-to-pricing ratio this wide suggests underwriters are keeping the pipeline stocked with optionality -- filing early to preserve a window -- rather than a genuine acceleration in completed listings.

3

Most of the filing volume comes from acquisition corps and smaller names rather than venture-backed growth companies, meaning the headline filing count overstates how much real VC-relevant liquidity is actually arriving.

4

For funds counting on IPO exits this year, filing volume is a weak leading indicator on its own -- the pricing conversion rate, not the filing count, is the number that actually predicts distributable proceeds.

The VC Read · Trace's Take

Trace Cohen

When you're modeling fund distributions off 'the IPO window is open' commentary, ask for the filing-to-pricing conversion rate over the last 90 days, not the filing count -- right now that ratio is roughly 2-in-23, which is a very different liquidity picture than the headline volume suggests.

Analysis

The gap between how many companies are filing to go public and how many are actually pricing widened again in late September. The SEC logged 12 new S-1 filings and 11 S-1/A or 424B4 pricing amendments in a single window between Sept. 24 and 25, spanning names from Elevation Acquisition Group to Interpace Biosciences to City Therapeutics. In that same stretch, only two names actually converted to a priced, trading listing: ADARx, which priced its $446 million Nasdaq debut, and Oura, which began its roadshow toward a targeted $15.6 billion valuation.

A filing-to-pricing ratio this wide is a pipeline-stocking signal more than an acceleration signal -- underwriters and issuers file early to preserve optionality on a favorable window without committing to price into it immediately, which is standard practice but means the raw filing count overstates near-term liquidity. It's also notable that most of the filing volume skews toward acquisition corps and smaller-cap names rather than the venture-backed growth companies most funds are actually counting on for distributions -- a distinction that matters because acquisition-corp filings can sit dormant for months waiting on a merger target, while operating-company S-1s are typically further along the pricing runway once filed.

For funds modeling exit timing this year, the practical read is to track the conversion rate, filings that actually price within a defined window, rather than the raw filing count, which is the metric most likely to get cited in year-end IPO recaps without the context of how few of those filings ever reach a trading ticker. A roughly 2-in-23 conversion rate over a single week is a small sample, but it's consistent with the broader pattern Pulse has tracked all fall: filing volume has stayed elevated while actual pricing events have clustered around a handful of high-conviction names rather than spreading broadly across the pipeline.
