Oura Filed. Here's Every Date Between Now and the First Trade.

What actually happened on September 3

Oura Inc., the Delaware company behind the Oura Ring, filed a Form S-1 — the registration statement a company files to sell shares to the public for the first time. It had already filed confidentially in May, which is the normal modern path: work through the SEC in private, then flip the document public when you are close enough to market the deal.

Bellipo is the first platform built entirely around the IPO lifecycle — from S-1 filing to first trade, lockup expiration, and beyond. We deliver real-time pipeline tracking, AI-powered S-1 briefs, and proprietary demand scoring, plus precision alerts: PING fires when pricing becomes official — typically the evening before trading, occasionally the morning of, always before the open — carrying the final offer price. STRIKE fires the instant the first trade prints. Retail investors get to prepare for IPO day with the same intelligence institutions take for granted.

The filing names the Nasdaq Global Select Market and the ticker OURA. Its headline financial fact is growth: revenue up 74% year over year in the period disclosed, on a subscription model layered over hardware. The pitch, in the company's own framing, is that the ring is the sensor and the recurring health data is the business.

Cover-page facts from the registration statement filed with the SEC on September 3, 2026.

Note the last four rows. Reported valuation figures have been circulating — press accounts have put the deal in the multi-billion range — but a number in a news story is not a number on file. Shares offered, price range and pricing date are genuinely blank right now, and anyone quoting them as facts is quoting a rumour with a decimal point.

Filed is not priced, and priced is not trading

Most people read "filed for IPO" and mentally file it next to "going public soon". Between those two states sit five distinct events, each of which leaves its own document on EDGAR. If you know the sequence, you know exactly which one you are waiting for.

1. Filed The S-1 goes public September 3, 2026 — done

   The registration statement is now on the public record with a ticker and an exchange. What it does not carry is a share count or a price range. That is normal: the cover page reserves those blanks until the deal is marketed.

2. Amendments S-1/A — the review round Weeks, not days

   The SEC comments; the company answers with an amended filing. The amendment that matters to a reader is the one that finally fills in shares offered and the price range. Every amendment before that is housekeeping.

3. Terms The launch amendment Typically the week the roadshow starts

   Share count plus a price range is what turns a filer into a deal. This is the first moment you can size the raise, estimate the float, and read demand against a number instead of a narrative.

4. Effective The EFFECT notice Usually the afternoon before pricing

   A short, boring, dateless notice on EDGAR that says the registration statement is effective. It is boring and it is the starting gun: after EFFECT, the deal can price that evening.

5. Priced The final number Evening, not morning

   The offer price is set after the close, usually the night before trading, occasionally the morning of — and it is frequently outside the range that was marketed. It lands as a press release and then as a 424B4 final prospectus.

6. First trade No scheduled time —:—

   This is the part nobody tells retail. The bell at 9:30 is not the open for a new listing. The First Print happens whenever the opening auction clears, which can be minutes or hours later, at a price with no relationship to the offer price.

7. Lock-up Whatever the clause says Read the clause, not the folklore

   Everyone repeats 180 days. The only number that counts is the one written in Oura's own lock-up section, and staged releases are common. Until we have read that clause, we will not print a date for it — and neither should anyone else.

The step readers consistently underestimate is the gap between pricing and the First Print. Pricing is an evening event. The open is an auction that clears when it clears. On recent debuts that gap has run from a few minutes to nearly three hours after the bell, and every minute of it is time the market is repricing a stock you cannot yet buy.

What to actually do between now and then

Nothing about a September filing tells you whether Oura is a good investment. What it tells you is that a clock has started, and that the two moments where a retail reader is structurally disadvantaged — the pricing evening and the opening auction — are both still ahead.

So the honest checklist is short. Wait for the amendment with terms; that is your first real number. Read the lock-up clause rather than assuming 180 days. And be present for the pricing evening and the First Print, because neither one sends you a calendar invite.

That last part is the whole reason Bellipo exists. We follow every US deal through five lifecycle stages, and we will send two signals on this one: PING the evening the terms become final, carrying the offer price, and STRIKE the instant the first share trades. Not a price alert. Not a news digest. Two moments, and the record behind them.
