FAQ

What equity award did Luxfer (LXFR) officer Jeffrey C. Moorefield receive?

Jeffrey C. Moorefield received an award of 3,200 Restricted Stock Units on March 16, 2026. These RSUs are time-based and represent stock-based compensation that can convert into Ordinary Shares if he remains employed through future vesting dates.

How do the new 3,200 RSUs for Luxfer (LXFR) vest over time?

The 3,200 Restricted Stock Units vest in three equal annual installments starting March 16, 2027. Each year, one-third of the units can convert into Ordinary Shares, aligning Moorefield’s compensation with longer-term company performance and continued service.

What happened when Luxfer (LXFR) RSUs granted in 2022 partially vested?

A portion of the time-based RSUs originally awarded on March 14, 2022 partially vested on March 16, 2026. This vesting converted 471 RSUs into 471 Ordinary Shares, increasing Moorefield’s direct share ownership before any shares were withheld for tax purposes.

Why were 192 Luxfer (LXFR) Ordinary Shares disposed of at $11.60?

The 192 Ordinary Shares at $11.60 were withheld to satisfy tax obligations arising from the RSU vesting. This disposition, coded as “F,” represents tax withholding by the issuer and is not an open-market sale initiated for investment reasons.

How many Luxfer (LXFR) Ordinary Shares does Moorefield hold after these transactions?

Following the RSU conversion and tax withholding, Moorefield directly holds 10,439 Ordinary Shares. This figure reflects his post-transaction ownership after 471 shares were issued from vesting and 192 of those shares were withheld to cover associated tax liabilities.

Are Moorefield’s Luxfer (LXFR) Form 4 transactions open-market buys or sells?

The transactions reflect equity compensation and related mechanics, not open-market trades. They include an RSU grant, the conversion of vested RSUs into Ordinary Shares, and a share disposition coded for tax withholding rather than discretionary buying or selling in the market.
