Read the filing behind the headline
Use item numbers from a real Form 8-K to see what was disclosed, which exhibit to open, and what the category alone cannot establish.

Form 8-K Item Decoder
Paste multiple item codes, then follow a source-linked guide to common events, earnings releases, financing disclosures and exhibits.
Decode an 8-K →Historical deal case studies
These completed offerings illustrate how new shares, existing-holder sales, and ATM capacity differ. Their figures belong to the dates in the cited filings; they are not live financing balances or a current watchlist. Open each record for its last-checked date and newer SEC filings.

Standard Nuclear’s July 2026 IPO
Compare gross and net proceeds and see why the 1.5 million-share option was excluded from the completed deal.
Explore Standard Nuclear →Compare three historical financing structures
| Measure | LightPath · LPTH | Standard Nuclear · STDN | Plug Power · PLUG |
|---|---|---|---|
| Structure | New shares + existing-holder resale | New-share IPO | At-the-market sales over time |
| Reported gross to issuer | $49,999,600 from the company sale; separate selling-holder proceeds excluded | $150,000,000; unexercised option excluded | $55.9 million from 2025 sales of 34,573,529 shares, per the 2025 Form 10-K |
| Later reported company outcome | $47.1 million net, per the FY26 Form 10-K | About $137.7 million net, per the June 2026 Form 10-Q | No ATM shares sold in the first half of 2026; $944.1 million remaining gross sales capacity at June 30 is not cash raised, per the June 2026 Form 10-Q |
These records cover different periods and transaction types. Remaining ATM capacity is permission to sell, not proceeds or issued shares. The amounts do not compare valuation, dilution, or shareholder returns; open each filing-backed record for its share-count context and dated caveats.
Another structure: sales over time

Plug Power: capacity is not cash raised
