Mountain Crest (MCAH) 10% Owner Liu Suying Forfeits 385,714 Shares

What Happened Liu Suying (reported as a 10% owner) disposed of 385,714 ordinary shares of Mountain Crest Acquisition 6 Corp via forfeiture on June 24, 2026. The shares were founder shares subject to forfeiture and were surrendered for no consideration (price/value: N/A). This was a forfeiture tied to the company's IPO mechanics, not an open-market sale.

Key Details

  • Transaction date: 2026-06-24; Form 4 filed: 2026-06-25 (timely).
  • Transaction code: J (other acquisition or disposition) — recorded as a disposition/forfeiture.
  • Shares forfeited: 385,714 ordinary shares, par value $0.0001; price and cash proceeds: N/A (forfeited for no consideration).
  • Shares owned after transaction: filing does not state remaining holdings; the filing reports the full 385,714 founder shares were forfeited.
  • Footnotes: F1 explains the forfeiture occurred because underwriters did not exercise the IPO over‑allotment option (the forfeited shares were the full founder block subject to that condition). F2 notes Dr. Suying Liu controls Mountain Crest Holdings 6 LLC (the direct holder) and may be deemed to share beneficial ownership, though he disclaims beneficial ownership except to any pecuniary interest.
  • Filing timeliness: reported the next day (not marked late).

Context This was an administrative forfeiture of founder shares linked to the IPO’s over‑allotment (greenshoe) outcome, not a typical insider sale for cash. For retail investors, forfeitures like this do not indicate a manager or insider converting shares to cash or trading on company prospects; they reflect IPO structuring. As a reported 10% owner via a holding LLC, Liu may be deemed to share beneficial ownership of those shares but disclaims beneficial ownership beyond any pecuniary interest.
