Klein Michael Stuart 4

What Happened
Michael Stuart Klein, CEO, President and Chairman of Churchill Capital Corp XII, is reported as acquiring 350,000 Class A ordinary shares at $10.00 per share for a total of $3,500,000 on April 29, 2026. The filing reflects a purchase (code P), which is typically viewed as a bullish signal compared with sales, though no motive can be inferred from the filing.

Key Details

• Transaction date: 2026-04-29; Price: $10.00; Total value: $3,500,000.
• Reported as a private placement purchase (shares underlying private placement units).
• Shares owned after the transaction: not specified in the filing.
• Footnote F1: These shares represent the Class A shares underlying private placement units (each unit = one Class A share + 0.1 warrant) acquired directly by Churchill Sponsor XII LLC (the Sponsor).
• Footnote F2: Mr. Klein is the controlling shareholder of M. Klein Associates, Inc., the managing member of the Sponsor, and therefore may be deemed to beneficially own the securities held by the Sponsor; he disclaims beneficial ownership except to the extent of any pecuniary interest.
• Filing date (accession): 2026-04-29 — same day as the reported transaction (no late filing indicated).

Context
This purchase was made via a private placement of units to the Sponsor rather than an open-market trade. Because the Sponsor holds the units and Mr. Klein controls the Sponsor, the disclosure reports his potential beneficial interest rather than a direct personal open-market purchase. For retail investors, purchases disclosed by insiders can be informative, but note the filing reflects an institutional/private-placement acquisition tied to the Sponsor structure and contains the disclaimers described above.
