Confidential Filing

When a company wants to go public, it first has to submit a thick set of documents to the securities regulator. In the US, this authority is called the SEC, and it oversees stock trading. These documents contain revenue, profit, losses, risks, and the names of the largest owners. Normally, such documents are immediately viewable by anyone on the internet. With a confidential filing, the company first submits them only to the regulator, confidentially and without publication. Only later, shortly before the actual IPO, are they made public.

Why companies reveal their numbers only later

The path to an IPO takes months. During this time, the regulator asks follow-up questions, and the company revises its documents, sometimes multiple times. If all intermediate versions were immediately public, any competitor could read along. They would learn how high the margins are, which customers pay the most, and where problems exist. That is exactly what a company wants to avoid as long as it is not yet certain whether the IPO will even take place.

Because backing out is costly for one’s reputation. If a company publicly announces it is going public and then cancels, it sounds like weakness. With the confidential process, it can quietly end the process. No one outside finds out. This lowers the barrier to even beginning to prepare for the step.

For investors, this has a downside. They learn about a planned IPO later than was previously customary. That’s why there is a fixed deadline: at the latest a few weeks before the investor roadshow, the documents must be disclosed. Confidentiality therefore applies only to the preparation phase, not permanently.

From confidential draft to public prospectus

The company sends a draft of the IPO prospectus to the SEC. In the US, this document is called Form S-1 and fully describes the business. The regulator reads it and sends back a list of comments. The company responds and submits a revised version. This back-and-forth process is often repeated three to five times.

You can think of it like the revision loop for a term paper. The teacher reads the draft, marks the gaps, and you make revisions. Only the finished version is submitted and graded. With a confidential filing, it is exactly this revision phase that stays under wraps.

In the end, all versions, along with the regulator’s comments, are published all at once. Confidentiality is therefore deferred, not eliminated. This process was made possible by a US law from 2012, the JOBS Act. Initially, only smaller companies with less than about a billion dollars in revenue were allowed to use it. Since 2017, the option has been open to practically any company, and most make use of it.

How to recognize it in stock market news

In business news, the term usually appears in a brief sentence: a company has “confidentially submitted documents for an IPO.” This information often comes from a short press release by the company itself. It is allowed to announce that it has filed, but does not have to disclose any figures. Such announcements are therefore noticeably devoid of content.

This is especially common among technology and AI companies. Companies like Airbnb, Spotify, or Reddit prepared their IPOs this way. For reporting, this means that several months often pass between the first announcement and the actual business figures. Anyone who wants to know how profitable a startup really is must wait for the publication of the prospectus.

A common misconception: a confidential filing is no guarantee of an IPO. Many companies file and then wait months for favorable market conditions. Some withdraw their plans entirely without anyone noticing. The announcement therefore only means that preparation has seriously begun.
