Is RUN diluting shareholders?

Read three numbers together: shares outstanding over time (238.5M as of 2026-05-01), warrants that can convert into new shares (846,943 reported), and how much cash runway remains (~7.4887813211845105 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-3ASR on file 2022-05-04

= 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+10% 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.

Warrants

Warrants outstanding: 846,943 underlying shares, as reported Dec 31, 2024 (10-K).

Reported exercise price: $0.01 (aggregate figure as tagged; individual tranches vary).

Rough fully diluted estimate: 239.4M = 238.5M O/S + 846,943 warrant shares. An estimate, not a filing figure: it ignores converts, options and RSUs, and the two inputs carry different as-of dates.

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 come from the dimensioned facts in the latest 10-Q/10-K instance document, exactly as the company tagged them; untagged tranches 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.
