Key Details

• Transaction date: 2026-05-11; Form filed: 2026-06-29 (filed late relative to the May transaction).
• Cash purchase: 60,537 shares at $15.00 = $908,055.
• Conversions (derivative security code C): multiple lines totaling many hundreds of thousands of shares (no cash price reported).
• Footnotes: F1 says Series F, E‑1 and E‑2 preferred stock converted into common immediately prior to the issuer's IPO; F2–F6 show the securities are held by HTX MCT1–4 entities for which GPG Ventures Houston is managing member. Managers Clay M. Heighten, MD, Carl D. Soderstrom and Gilbert G. Garcia II share voting and dispositive power.
• Shares owned after the transaction are not specified in this excerpt of the filing; this Form 4 is the fifth of five filings covering all related reporting persons (split because more than 10 reporting persons).

Context

• The $908K open-market/private purchase is a straightforward buy; purchases are often watched by investors as a more bullish signal than routine sales, but the conversion activity here reflects corporate capital-structure changes (preferred-to-common conversions) tied to the issuer's IPO mechanics rather than typical insider trading.
• This is an institutional/affiliate holder (10% owner via affiliated LLCs), not an individual officer exercising options; conversions of derivatives usually reflect corporate events and may not involve cash changing hands.
• The filing was submitted over a month after the reported transactions, so it was late relative to normal Form 4 timing requirements.
