Columbus Acquisition Corp/Cayman Islands (COLA)
CIK 2028201 · all EDGAR filings →
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: 4.5M shares as of Aug 4, 2026 (10-Q). Share count fell from 7.9M to 4.5M between Nov 14, 2025 and Mar 19, 2026, a pattern consistent with a reverse split (roughly 1-for-2); simultaneous issuance can skew the raw ratio, so confirm in the filings. The red bar marks the cliff.

Warrants
| Tranche | Warrants | Exercise price | Term | Notes |
|---|---|---|---|---|
| Public Rights | 6.0M | not tagged | — | — |
| Private Rights | 234,290 | not tagged | — | — |
Tranches exactly as the company dimensioned them in its 10-Q filed Aug 4, 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.
No warrant figures tagged in this filer’s XBRL facts. That means the company has not reported them in structured form; it does not prove no warrants exist. The exhibits are the ground truth.
Convertible notes
| Note | Principal | Carrying | Conv. price | Rate | If converted |
|---|---|---|---|---|---|
| Target Extension Note | $100,000 | — | $10 | — | ~10,000 sh |
| Working Capital Loans | not tagged | — | $10 | — | — |
| Target Extension Notes | not tagged | — | $10 | — | — |
| Convertible Promissory Note | not tagged | — | $5 | — | — |
If every note above converted at its tagged price: ~10,000 new shares on 4.5M currently outstanding. An estimate from principal ÷ conversion price, with inputs carrying different as-of dates; make-whole adjustments, capped calls and partial repurchases are not modeled.
Notes exactly as the company dimensioned them in its 10-Q filed Aug 4, 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 | 4.5M | Aug 4, 2026 |
| + Public Rights (if exercised) | 6.0M | Jun 30, 2026 |
| + Private Rights (if exercised) | 234,290 | Jun 30, 2026 |
| + Target Extension Note (if fully converted) | 10,000 | May 5, 2026 |
| Fully diluted estimate | 10.7M | +138.9% 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.
