Is SHPH diluting shareholders?

Read three numbers together: shares outstanding over time (5.9M as of 2026-05-15), warrants that can convert into new shares (1.3M reported), and how much cash runway remains (~1.3794391163136777 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 (cash need)

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

Offering ability

MEDIUM$9.1M registered

= total registered offering amount from the fee exhibits of live registrations (bands: $1M / $20M)

registered capacity, not remaining: amounts already taken down are not subtracted yet

Overhead supply

MEDIUMwarrants = 22% 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-58% 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~1.4 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: 5.9M shares as of May 15, 2026 (10-Q). Share count fell from 11.0M to 1.1M between May 8, 2025 and Aug 11, 2025, a pattern consistent with a reverse split (roughly 1-for-10); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Warrants outstanding: 1.3M 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: 7.1M = 5.9M O/S + 1.3M 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
Convertible Bridge Notes	not tagged	$600,000	not tagged	1.07%	—

Notes exactly as the company dimensioned them in its 10-Q filed May 15, 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	5.9M	May 15, 2026
+ Warrants (aggregate, as tagged) (if exercised)	1.3M	Dec 31, 2025
Fully diluted estimate	7.1M	+21.9% 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.

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.
