Is LGVN diluting shareholders?

Read three numbers together: shares outstanding over time (see chart), warrants that can convert into new shares (2.6M reported), and how much cash runway remains (~6.4855993563958165 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

HIGHworst of 2 computed sub-ratings (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$52.0M 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

NOT COMPUTEDunder 3 years of share history on file

= share count now vs 3 years ago

Cash need

MEDIUM~6.5 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

Fewer than two cover-page share counts on file, so there is no history to chart.

Cash runway

Going-concern warning

auditor flagged substantial doubt

The company itself flagged going-concern doubt in a filing.

Tranches exactly as the company dimensioned them in its 10-Q filed Aug 12, 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: 2.6M underlying shares, as reported Aug 12, 2024 (10-Q).

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

Convertible notes

No convertible-note facts tagged in the 10-Q filed Aug 12, 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.
