Dilution profile // every instrument, one screen, from SEC filings

Rein Therapeutics, Inc. (RNTX)

CIK 1420565 · all EDGAR filings →

Overall dilution risk
HIGHworst of 3 computed signals (offering ability)
= the worst band among the computed sub-ratings, no hidden weighting
not every sub-rating was computable; treat as a floor
Offering ability
HIGH$73.6M registered
= total registered offering amount from the fee exhibits of live registrations (bands: $1M / $20M)
one or more live registrations had no structured fee data, so the true total is AT LEAST this
Overhead supply
NOT COMPUTEDno warrant count tagged in XBRL
= warrant shares outstanding divided by current shares outstanding
absence of a tag is not proof of absence of warrants
Historical dilution
HIGH+1784% O/S in 3y
= share count now vs 3 years ago (bands: 30% / 100%); a reverse split pushes this negative
a reverse-split-sized cliff is in this window; read the chart
Cash need
HIGH~2.8 months of runway
= 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.

Shares outstanding over time

2021-03-192026-05-13

Latest: 85.5M shares as of May 13, 2026 (10-Q). Share count fell from 90.8M to 4.5M between Oct 28, 2022 and Mar 16, 2023, a pattern consistent with a reverse split (roughly 1-for-20); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Tranches exactly as the company dimensioned them in its 10-Q filed May 15, 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.

No warrant figures tagged in this filer’s XBRL facts. That means the company has not reported them in structured form; it does not prove no warrants exist. The exhibits are the ground truth.

Convertible notes

No convertible-note facts tagged in the 10-Q filed May 15, 2026. If convertible notes exist, their terms live in exhibit prose for this filer and are not parsed; absence of a tag is not proof of absence. The exhibits are the ground truth.

Source: SEC EDGAR XBRL company facts and filing metadata, fetched live and cached briefly. Share counts are cover-page figures with their form named. Warrant tranches and convertible notes come from the dimensioned facts in the latest 10-Q/10-K instance document, exactly as the company tagged them; untagged tranches and notes are absent, not disproven. Nothing on this page is manually verified and nothing is behind a login: what free data supports is shown, what it cannot support is stated. Not investment advice.
