Is NDRA diluting shareholders?

Read three numbers together: shares outstanding over time (1.3M as of 2026-05-15), warrants that can convert into new shares (31,666 reported), and how much cash runway remains (~11.159259192082366 months). 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

MEDIUMworst of 4 computed signals (cash need)

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

Offering ability

LOWno live registration found

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

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

LOW-83% 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

MEDIUM~11.2 months of runway

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

the company itself flagged going-concern doubt

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

Latest: 1.3M shares as of May 15, 2026 (10-Q). Share count fell from 72.4M to 536,908 between Aug 14, 2024 and Nov 19, 2024, a pattern consistent with a reverse split (roughly 1-for-135); 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.

Warrants outstanding: 31,666 underlying shares, as reported Dec 31, 2025 (10-K).

Reported exercise price: $0.001 (aggregate figure as tagged; individual tranches vary).

Rough fully diluted estimate: 1.3M = 1.3M O/S + 31,666 warrant shares. An estimate, not a filing figure: it ignores converts, options and RSUs, and the two inputs carry different as-of dates.

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.

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.
