Standard Nuclear (STDN) 10% Owner Converts 14M Preferred to Common

What Happened

• ST-1014 Fund I (reported as a 10% owner) converted 14,000,000 shares of Series Seed-1 Preferred into 14,000,000 shares of Class A Common Stock of Standard Nuclear (STDN) on July 17, 2026. The conversion was on a 1-for-1 basis immediately prior to the company’s IPO closing (per footnote). There was no cash paid or received in the conversion; the transaction shows a $0.00 disposition amount for the derivative security.

Key Details

• Transaction date: 2026-07-17. Form 4 filed: 2026-07-23 (filed after the 2-business-day reporting window — appears late).
• Reported transactions: Acquired 14,000,000 shares via conversion; derivative position of 14,000,000 was recorded as disposed at $0.00.
• Price/Proceeds: $0.00 (conversion; no cash exchanged).
• Shares owned after transaction: Not specified in the provided data.
• Notable footnotes:
  • F1: Series Seed-1 Preferred automatically converted 1-for-1 into Class A common immediately before the IPO; the preferred had no expiration.
  • F2: ST-1014 may be affiliated with other Fundomo entities, but voting/dispositive power over the shares held directly by ST-1014 has been irrevocably delegated to an unaffiliated third‑party adviser.
  • F3: The reporting person disclaims beneficial ownership except to the extent of pecuniary interest.
• Filing timeliness: Report appears late (filed 6 days after the reported transaction date), which is a reporting compliance issue but does not by itself indicate trading intent.

Context

• This was a conversion of a derivative/security (preferred stock into common) tied to the company’s IPO, not an open-market purchase or sale. Conversions at IPO are common corporate events and do not necessarily signal insider sentiment. Because ST-1014 is a 10% institutional holder with voting rights delegated to an external adviser, this filing reflects an institutional conversion rather than an individual officer/director trade.
