Insights

Equity compensation analyst

Routine RSU vesting and tax withholding with performance targets met.

Luxfer Holdings granted and vested several restricted stock unit awards for officer Mead Howard Ioan, then converted them into Ordinary Shares. These include both time-based tranches and performance-based awards tied to earnings per share and relative total shareholder return goals.

Performance-based RSUs vested at 221% and 125% of target after meeting EPS growth and TSR goals for the period ended December 31, 2025, indicating the company hit those internal performance hurdles. Shares were issued at a nominal $1.00 per Ordinary Share, consistent with the 1-for-1 RSU conversion described in the footnotes.

The filing also shows tax-withholding dispositions totaling 6,357 Ordinary Shares at about $11.80 per share, which are not open-market sales but shares withheld to satisfy tax liabilities on vesting. After these transactions, Howard Ioan directly holds 18,310 Ordinary Shares. Overall, this appears to be routine compensation and tax settlement activity rather than a discretionary market trade.

FAQ

What did Luxfer Holdings (LXFR) insider Mead Howard Ioan report in this Form 4?

He reported RSU vesting, exercises, and related tax withholding. Several restricted stock unit awards vested and were converted into Ordinary Shares, and a portion of those shares was withheld to cover tax obligations, resulting in updated direct share ownership.

How many Luxfer Holdings Ordinary Shares does Mead Howard Ioan now hold directly?

He now directly holds 18,310 Ordinary Shares. This figure reflects RSU exercises into Ordinary Shares on March 17–18, 2026, offset by shares withheld at vesting to satisfy tax liabilities, as disclosed in the non-derivative transaction entries.

Were the Luxfer (LXFR) insider transactions open-market buys or sells?

No, they were equity compensation events, not market trades. The Form 4 shows RSU grants and exercises (code M and A) and tax-withholding dispositions (code F). Shares withheld under code F pay taxes on vesting, rather than representing discretionary open-market sales.

What performance goals triggered Luxfer’s performance-based RSU vesting for Mead Howard Ioan?

EPS growth and relative TSR goals drove vesting. Footnotes state performance-based RSUs vested at 221% and 125% of target after achieving earnings per share growth goals and relative total shareholder return goals for the performance period ended December 31, 2025.

How many Luxfer Holdings RSUs did Mead Howard Ioan exercise in these transactions?

He exercised 14,695 restricted stock units into Ordinary Shares. This total comes from multiple derivative exercises coded M, including both time-based vesting tranches and fully vested performance-based RSU awards granted in March 2024 and March 2025.

What was the purpose of the share dispositions reported under code F for Luxfer (LXFR)?

The F-code dispositions covered tax obligations on vesting. A total of 6,357 Ordinary Shares were withheld at prices around $11.80–$11.82 per share to pay exercise price or tax liabilities, rather than being sold in the open market.
