Dilution profile // every instrument, one screen, from SEC filings

Arcadia Biosciences, Inc. (RKDA)

CIK 1469443 · all EDGAR filings →

Overall dilution risk
HIGHworst of 4 computed signals (historical dilution)
= the worst band among the computed sub-ratings, no hidden weighting
Offering ability
MEDIUM$12.3M 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
LOWwarrants = 7% 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
HIGH+116% 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
MEDIUM~9.5 months of runway
= 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

2021-08-092026-05-07

Latest: 2.1M shares as of May 7, 2026 (10-Q). Share count fell from 24.6M to 857,572 between Nov 7, 2022 and Mar 23, 2023, a pattern consistent with a reverse split (roughly 1-for-29); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Tranches exactly as the company dimensioned them in its 10-Q filed May 14, 2026. Groupings can overlap (a “Series E and F” row is not additive with a “Series E” row), so do not sum this column. A tranche the filer did not tag is absent here, not absent from the cap table. DOWN-ROUND = the filer tagged price-protection accounting scoped to that tranche.

Warrants outstanding: 151,575 underlying shares, as reported Mar 31, 2026 (10-Q).

Reported exercise price: $6.31 (aggregate figure as tagged; individual tranches vary).

Rough fully diluted estimate: 2.2M = 2.1M O/S + 151,575 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 May 14, 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.

Fully diluted estimate2.2M+9.4% 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.

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.
