What Happened
Larry Padfield, a director of Innospec Inc. (IOSP), sold a total of 594 shares in open-market transactions on February 27, 2026. The filing reports two weighted-average sale lines: 287 shares at a weighted average price of $76.30 ($21,898) and 307 shares at $76.79 ($23,575), for combined proceeds of about $45,473.

Key Details

  • Transaction dates and prices:
    • 2026-02-27 — 287 shares @ $76.30 (weighted avg) — $21,898 (Table I)
    • 2026-02-27 — 307 shares @ $76.79 (weighted avg) — $23,575 (Table I)
    • Total sold: 594 shares for ~$45,473.
  • Footnotes: This is an amended Form 4/A (filed 2026-03-06) correcting the transaction prices to weighted averages. The underlying trades were executed in multiple transactions at prices ranging roughly $75.5001 to $76.55 (first block) and $76.555 to $77.0713 (second block). The filer offers to provide the full breakdown upon request.
  • Shares owned after transaction: not reported in the provided filing (total holdings after the sales not disclosed here).
  • Filing timeliness: original Form 4 was filed March 3, 2026 (within the usual two-business-day reporting window for a Feb 27 trade); this amendment corrects reported prices and was filed March 6.
  • Other notes: Transactions are reported as open-market sales (code S). No 10b5-1 plan, tax-withholding disposition, or option exercise is disclosed in this amended filing.

Context
These are open-market sales by a company director and were split across multiple trades (hence weighted-average prices and the amended filing). Sales by insiders are common for liquidity or portfolio-management reasons; the filing itself provides corrected price detail but does not state the insider’s remaining holdings, so this report documents the disposal without indicating additional context about Padfield’s overall stake or intent.
