Mountain Crest Acquisition 6 (MCAH) 10% Owner Liu Suying Buys Stock

What Happened

  • Liu Suying (reported as a 10% owner) purchased 25,000 ordinary shares of Mountain Crest Acquisition 6 Corp. on 2026-05-01 at $10.00 per share for a total of $250,000. On the same date the filer also acquired 25,000 derivative rights/units (reported with no per-share price) that are tied to the company's structure.
  • These are purchases (not sales), which are generally considered a more informative insider action because they show the insider adding to a position rather than reducing it. The derivative rights do not convert into ordinary shares immediately.

Key Details

  • Transaction date: May 1, 2026.
  • Purchases: 25,000 shares @ $10.00 (total $250,000); 25,000 derivative rights/units reported at N/A.
  • Shares owned after transaction: Not disclosed in the provided filing excerpt.
  • Footnotes:
    • F1: The reporting person acquired units consisting of shares and rights.
    • F2: The rights automatically convert into one-fourth (1/4) of one ordinary share upon consummation of the registrant's initial business combination (per the prospectus filed April 6, 2026). (So each right would convert into 0.25 ordinary share upon that event.)
    • F3: Liu Suying controls Mountain Crest Holdings 6 LLC and may be deemed to share beneficial ownership of securities held by that LLC; Liu disclaims beneficial ownership except to the extent of any pecuniary interest.
  • Filing timeliness: The Form 4 was filed May 5, 2026 for the May 1 transaction — this appears later than the usual two-business-day reporting window and is flagged as a late filing concern in the record.

Context

  • The derivative rights are contingent securities tied to the company’s planned initial business combination (a SPAC-style structure). They convert into a fraction of an ordinary share only when that business combination is consummated, so they are not the same as immediately tradable shares.
  • Because the reported ownership is connected to an affiliated LLC that Liu controls, the filing reflects ownership through that entity rather than necessarily direct personal holdings.
