Is OPEN diluting shareholders?

Read three numbers together: shares outstanding over time (964.7M as of 2026-04-30), warrants that can convert into new shares (19.4M reported), and how much cash runway remains. A company short on cash with live registrations is structurally likely to issue shares.

Where do these numbers come from?

SEC EDGAR only: the XBRL company-facts API for shares, warrants and cash, and filing metadata for registrations and pricings. Every figure shows its source form, and nothing here is estimated by us beyond the arithmetic stated next to it.

Why might a warrant tranche be missing from the table?

The tranche table is built from the dimensions the company tagged in its own 10-Q or 10-K XBRL. A tranche the filer chose not to dimension does not appear, and its absence proves nothing: the exhibits remain the ground truth. Everything shown carries the filing it came from.

Overall dilution risk

HIGHworst of 4 computed signals (offering ability)

= the worst band among the computed sub-ratings, no hidden weighting

Offering ability

HIGHS-3ASR on file 2024-05-02

= is there a registration (S-1/S-3 family) on file without a later withdrawal

no structured fee data on the live registrations, so this is a yes/no, not a size

Overhead supply

LOWwarrants = 2% of O/S

= warrant shares outstanding divided by current shares outstanding (bands: 20% / 50%)

warrants only; converts, ATMs and equity lines are not in free structured data, so the true overhead is AT LEAST this

Historical dilution

MEDIUM+46% O/S in 3y

= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative

Cash need

LOWoperating cash flow positive

= cash vs trailing operating burn (bands: 6mo / 24mo; positive operating CF = low)

Same rating bands the category standard uses, but free, with the formula on the chip and the gaps in the data said out loud.

Tranches exactly as the company dimensioned them in its 10-Q filed May 7, 2026 →. Groupings can overlap (a “Series E and F” row is not additive with a “Series E” row), so do not sum this column. A tranche the filer did not tag is absent here, not absent from the cap table. DOWN-ROUND = the filer tagged price-protection accounting scoped to that tranche.

Warrants outstanding: 19.4M underlying shares, as reported Jun 30, 2021 (10-Q).

Reported exercise price: $11.5 (aggregate figure as tagged; individual tranches vary).

Balance-sheet fair value of warrants: $0 as of Dec 31, 2021.

Rough fully diluted estimate: 984.1M = 964.7M O/S + 19.4M warrant shares. An estimate, not a filing figure: it ignores converts, options and RSUs, and the two inputs carry different as-of dates.

Warrant tranches come from the dimensioned facts in the latest 10-Q/10-K instance document, exactly as the company tagged them; untagged tranches are absent, not disproven.
