ICON (ICLR) CFO Nigel Clerkin Sells Shares to Cover Taxes

What Happened

• Nigel Clerkin, Chief Financial Officer of ICON plc (ICLR), had restricted share units vest and exercised/converted derivatives on August 10, 2026; he subsequently sold 2,267 shares in open-market transactions on August 11, 2026 to cover tax withholding. The sales totaled approximately $372,445 (weighted-average prices across several trades).
• Concurrently, Clerkin received new equity awards on August 10, 2026 (a stock option grant and additional restricted share units) with multi-year vesting schedules.

Key Details

• Transaction dates: Vesting/exercise/conversion and grants on Aug 10, 2026; open-market sales on Aug 11, 2026.
• Sales: 237 shares @ $162.72 (≈ $38,565); 259 shares @ $163.77 (≈ $42,416); 1,591 shares @ $164.47 (≈ $261,672); 180 shares @ $165.51 (≈ $29,792). Total ≈ $372,445 for 2,267 shares.
• Vesting / conversions: 918 RSUs vested (grant dated Mar 6, 2025) and 3,375 RSUs vested (grant dated May 22, 2025) on Aug 10, 2026; a portion of vested shares were withheld/sold for taxes.
• New awards on Aug 10, 2026: ~14,164 stock options (vesting in ~4 equal installments from Mar 8, 2027–2030) and ~4,793 restricted share units (vesting in three installments from Mar 8, 2027–2029). Options carry multi-year exercisability and expiration provisions per filing footnotes.
• Reason for sale: Footnote F4 confirms the sales were "sell-to-cover" transactions to satisfy tax withholding obligations — not discretionary market sales.
• Price ranges: The filing reports weighted-average prices for grouped sales; footnotes list the per-trade price ranges (approx. $162.08–$166.16 across blocks).
• Shares owned after transaction: Not disclosed on this Form 4.
• Filing timeliness and exemption: Report filed Aug 12, 2026 covering Aug 10–11 transactions. As a foreign private issuer, the filer states these transactions are exempt from Sections 16(b) and 16(c).

Context

• This was primarily a routine sell-to-cover following RSU vesting (common for executives to meet tax withholding). The filing also documents new option and RSU grants with future vesting schedules — these are awards, not immediate purchases that would signal personal bullish investing.
• For derivative transactions: the report shows conversion/settlement of RSUs (contingent rights to shares) and option grants; some vested/converted shares were withheld/sold for taxes (zero net-proceeds entries reflect withholding).
