BARNES CORBIN 4

What Happened
Corbin Barnes, Senior Vice President of Corporate Development and Investor Relations at Innospec Inc. (IOSP), acquired 1,730 shares on February 16, 2026 upon settlement of a performance-based restricted stock unit (RSU) award. The Form 4 reports an acquisition price of $0.00 for the shares, reflecting that these shares were issued on vesting rather than bought on the open market.

• Transaction type/code: Award/settlement (code A).
• Shares acquired: 1,730; reported acquisition price: $0.00.

Context
Settlement of performance-based RSUs converts previously granted units into actual shares when performance and/or service conditions are met. This is a compensation/vesting event (not a market purchase or sale) and should be viewed as the receipt of awarded equity rather than an insider expressing a buy or sell view. Retail investors who want a dollar estimate can multiply 1,730 by the stock price on or shortly after Feb 16, 2026 to approximate the economic value at vesting.
