Is GLSI diluting shareholders?

Read three numbers together: shares outstanding over time (14.7M as of 2026-05-26), warrants that can convert into new shares (20,174 reported), and how much cash runway remains (~7.478348058945757 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 4 computed signals (offering ability)

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

Offering ability

HIGHS-3 on file 2024-10-07

= 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 = 0% 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+14% O/S in 3y

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

Cash need

MEDIUM~7.5 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

Latest: 14.7M shares as of May 26, 2026 (10-Q).

Warrants

Warrants outstanding: 20,174 underlying shares, as reported Jun 30, 2025 (10-Q).

Reported exercise price: $7.1875 (aggregate figure as tagged; individual tranches vary).

Balance-sheet fair value of warrants: $37,978 as of Jun 30, 2025.

Rough fully diluted estimate: 14.7M = 14.7M O/S + 20,174 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 Jun 4, 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.

Fully diluted build-up

Shares outstanding plus every potential-share instrument the filer tagged in XBRL, each at its own as-of date. An estimate assembled from filed figures, not a filing figure itself.

Shares outstanding	14.7M	May 26, 2026
+ Warrants (aggregate, as tagged) (if exercised)	20,174	Jun 30, 2025
Fully diluted estimate	14.7M	+0.1% vs O/S

Still excluded, because the filer does not tag them in countable form: employee options and RSUs, any instrument living only in exhibit prose, and instruments above missing a share count. Inputs carry different as-of dates, shown per row. Each figure traces to the tranche and note tables above and their cited filings.

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.
