What semiconductor IPO filings reveal about foundry commitment exposure

Most fabless companies disclose very little about their foundry obligations — but S-1 and F-1 registration statements are the exception. SEC rules require full material contract disclosure at IPO, making them the only
public source where these terms appear unredacted.

We analyzed 49 semiconductor IPO filings to extract purchase commitment data from the Commitments & Contingencies notes. Here is what the data shows:

$47M — median year-1 purchase obligation for a fabless company at IPO. This is money committed before a chip ships, before a customer pays, before tape-out passes.

72% — median share of the total commitment due in year 1. Most companies are front-loaded, meaning the foundry collects the majority of the obligation in the first 12 months.

25% — share of companies that disclose commitment data at all. Most founders negotiating today have no public benchmark to reference.

A few other signals from the corpus: take-or-pay clauses appear frequently but terms are rarely disclosed in detail. Yield floor thresholds show up in roughly a third of foundry agreements where the clause is present.

Curious whether this matches what others in the community have seen in practice — are these numbers surprising or expected given your experience?
