Is TANH diluting shareholders?

Read three numbers together: shares outstanding over time (6.2M as of 2026-04-30), warrants that can convert into new shares (18.9M reported), and how much cash runway remains (~68.38211278424775 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 (overhead supply)

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

Offering ability

MEDIUM$17.5M 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

HIGHwarrants = 304% 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

MEDIUM+64% 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

LOW~68.4 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: 6.2M shares as of Apr 30, 2026 (20-F). Share count fell from 35.9M to 6.4M between Dec 31, 2020 and Dec 31, 2021, a pattern consistent with a reverse split (roughly 1-for-6); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants

Warrants outstanding: 18.9M underlying shares, as reported Dec 31, 2024 (20-F).

Reported exercise price: $1.83 (aggregate figure as tagged; individual tranches vary).

Rough fully diluted estimate: 25.1M = 6.2M O/S + 18.9M 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

The latest 10-Q/10-K instance document could not be checked just now, so nothing is shown rather than guessed. Try again shortly.

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	6.2M	Apr 30, 2026
+ Warrants (aggregate, as tagged) (if exercised)	18.9M	Dec 31, 2024
Fully diluted estimate	25.1M	+303.7% 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.
