Cam-Phung Michael Tam 4

What Happened

• Michael Cam-Phung, the managing member of Cambridge Sponsor LLC and a 10% owner of Cambridge Acquisition Corp. (CAQ), was involved in a private placement purchase on 2026-02-09. The transaction consisted of 495,500 Class A ordinary shares acquired at $10.00 per share for a total of $4,955,000. This was a purchase (a net inflow of shares to the Sponsor).

Key Details

• Transaction date and price: February 9, 2026 — 495,500 Class A shares at $10.00 each.
• Total value: $4,955,000.
• How the shares were purchased: Private placement units (each unit = 1 Class A share + 1/3 of a warrant).
• Warrant terms: Each whole warrant exercisable into one Class A share at $11.50 (units include one-third of a warrant).
• Record vs beneficial ownership: Cambridge Sponsor LLC is the record holder of the shares. As managing member of the Sponsor, Mr. Cam-Phung holds voting and investment discretion and may be deemed to beneficially own the shares held by the Sponsor; he disclaims beneficial ownership except to the extent of any pecuniary interest.
• Other Sponsor holdings: Footnote excludes 7,666,667 Class B ordinary shares held by the Sponsor under a subscription agreement.
• Filing timeliness: Report covers 2026-02-09 and was filed 2026-02-10 (filed promptly).

Context

• This was a sponsor private placement purchase typical in SPAC transactions (units bought at $10/unit). The inclusion of warrants means the purchase also conveys fractional warrant rights that could convert to shares if exercised at $11.50.
• Because the shares are held by an institutional Sponsor and Mr. Cam-Phung’s role is managerial for that Sponsor, this is institutional/sponsor-related activity rather than routine personal open-market trading by an executive.
