PAULSON & CO. INC. 4

What Happened

• Paulson & Co. Inc., reported as a 10% owner of Acadian Asset Management Inc. (AAMI), sold 1,900,000 shares on June 17, 2026 at $77.25 per share, for a total of $146,775,000. The transaction is reported as a sale (code S) described as an open market or private sale. This is a disposition (sale), which is often routine for institutional managers.

Key Details

• Transaction date and price: 2026-06-17 at $77.25 per share (total proceeds $146,775,000).
• Transaction type: Sale (code S) — open market or private sale.
• Filing date: Form 4 filed 2026-06-22 (5 days after the trade). SEC Form 4s are generally due within two business days, so this filing appears late relative to that deadline.
• Shares owned after transaction: Not specified in the provided filing extract.
• Footnotes: F1 — Paulson is the investment manager of funds that own the reported shares; John Paulson is the controlling person of Paulson and the securities are owned by those funds. F2 — Paulson and John Paulson may be deemed to indirectly beneficially own the securities; the filing includes a statement under Rule 16a-1(a)(4) that it is not an admission of beneficial ownership for Section 16 purposes.
• Insider type: Institutional 10% owner (funds managed by Paulson), not an executive-level trade.

Context

• This sale was executed by an institutional manager on behalf of funds, which is typically portfolio-level activity (rebalancing, liquidity management, or investor flows) rather than a direct signal about company fundamentals. Because the filing appears to have been made after the usual two-business-day Form 4 window, investors may note the late report but should rely on multiple signals (financials, filings, and other insider activity) when assessing company outlook.
