Is ISCO diluting shareholders?

Read three numbers together: shares outstanding over time (8.0M as of 2026-08-11), warrants that can convert into new shares (4.0M 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

MEDIUMworst of 4 computed signals (overhead supply)

= 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

MEDIUMwarrants = 49% 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

LOW0% O/S in 3y

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

Cash need

= 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: 8.0M shares as of Aug 11, 2026 (10-Q). Share count fell from 270.7M to 2.0M between May 5, 2015 and Aug 11, 2015, 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.

Warrants

Warrants outstanding: 4.0M underlying shares, as reported Dec 31, 2019 (10-K).

Reported exercise price: $1.75 (aggregate figure as tagged; individual tranches vary).

Balance-sheet fair value of warrants: $9.5M as of Jun 30, 2013.

Rough fully diluted estimate: 12.0M = 8.0M O/S + 4.0M 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

Note	Principal	Carrying	Conv. price	Rate	If converted
Unsecured Non Convertible Promissory Note	$2.4M	—	not tagged	—	—

Notes exactly as the company dimensioned them in its 10-Q filed Aug 13, 2026 →. Principal is face amount as tagged, not what remains after repurchases unless the filer updated the tag. A note the filer did not dimension is absent here, not absent from the balance sheet; the exhibits stay 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	8.0M	Aug 11, 2026
+ Warrants (aggregate, as tagged) (if exercised)	4.0M	Dec 31, 2019
Fully diluted estimate	12.0M	+49.4% 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.
