Ramos Vittini Janelle Amanda 4

What Happened

• Janelle Amanda Ramos Vittini, General Counsel of Luxfer Holdings plc, had 780 restricted stock units (RSUs convert/derivatives) settle on March 17, 2026. The RSUs converted 1-for-1 into ordinary shares (nominal $1.00 per share).
• To cover the tax liability on the vesting, 488 shares were withheld/disposed at $11.80 per share, yielding $5,758. The filing also reports the conversion/exercise-related derivative entries for the 780 shares.

Key Details

• Exercise/conversion: 780 RSUs converted 1-for-1 into ordinary shares (nominal $1.00 per share) (footnote F1).
• Footnote F2: the 780 shares represent 25% of RSUs granted March 17, 2025; remaining RSUs vest in equal tranches on March 17, 2027, 2028 and 2029.

Context

• This was a routine vesting/conversion of RSUs, not an open-market purchase or directional investment by the insider. The disposal of 488 shares was to satisfy tax withholding—a common, administrative step after RSU vesting.
