"Share Plans (a) The Luxfer Group Employee Share Ownership Plan The trust In 1997, the Company established an employee benefit trust (""the ESOP"") with independent Trustees, to purchase and hold shares in the Company in trust to be used to satisfy options granted to eligible senior employees under the Company's share plans established from time to time. The ESOP was established with the benefit of a gift equivalent to the set up and running costs. Purchase monies and costs required by the ESOP Trustees to purchase shares for and under the provisions of the trust are provided by way of an interest free loan from a Company subsidiary. The loan is repayable, in normal circumstances, out of monies received from senior employees when they exercise options granted to them over shares. Surplus shares are held by the ESOP Trustees to satisfy future option awards. The ESOP Trustees have waived their right to receive dividends on shares held in trust. The Remuneration Committee is charged with determining which senior employees are to be granted options, and in what number, subject to the relevant plan rules.

"Pension Plans The Company operates funded defined benefit pension plans in the U.K., the U.S. and France. The levels of funding are determined by periodic actuarial valuations that take into account changes in actuarial assumptions, including discount rates and expected returns on plan assets. The assets of the plans are generally held in separate Trustee-administered funds. The Company also operates defined contribution plans in the U.K., the U.S., Australia and Canada. The ""10% corridor"" method for recognizing gains and losses has been adopted. This methodology means that cumulative gains and losses up to an amount equal to 10% of the higher of the liabilities and the assets (the corridor) have no impact on the pension cost. Cumulative gains or losses greater than this corridor are amortized over the average future lifetime of the members in the plans. The Companys principal defined benefit pension arrangement is the U.K. Luxfer Group Pension Plan (the Plan), which closed to new members in 1998, with new employees thereafter eligible for a defined contribution plan. In April 2016, the Plan was closed to future benefit accrual, with affected members offered participation in a defined contribution plan. In January 2026, subsequent to the 2025 year-end, the Plans Trustee entered into a full buy-in contract with a U.K. insurer, designed to substantially match the Plans benefit obligations; the impact of this transaction is not included in the Companys 2025 financial statemen …

7. Income Taxes We manage our affairs so that we are centrally managed and controlled in the United Kingdom (U.K.) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates. The effective income tax rate for the first six months ended June 28, 2026 , was 29.4%, compared to 34.1% for the first six months ended June 29, 2025 . In 2026 the rate was impacted by non-deductible expenses. Cash income taxes paid, net of refunds, are disclosed within supplementary cash flow information in the Consolidated Statements of Cash Flows. …

5. Defined benefit pension credit On January 8, 2026, the Trustee of the Luxfer Group Pension Plan (LGPP) entered into a full buy-in contract with a U.K. insurer, Aviva. The buy-in is designed to substantially match the Plans benefit obligations with corresponding cash flow payments from the insurer, with effect from March 2026 payroll, in exchange for an agreed premium. The buy-in does not constitute a settlement event under ASC 715, CompensationRetirement Benefits and therefore does not require remeasurement of the Plans funded status for the Quarter ended March 29, 2026. Accordingly, the net defined benefit asset recognized at June 28, 2026 remains consistent with the year-end measurement as of December 31, 2025. The defined benefit pension charge was $0.1 million in the second quarter of 2026, compared to a $0.6 million credit in the second quarter of 2025. For the first six months of 2026, the defined benefit pension charge was $0.1 million, compared to a $1.2 million credit in the first six months of 2025. The year-over-year movements primarily reflect lower expected returns on plan assets compared to the prior year periods. In addition, on January 8, 2026, the Trustee of the Luxfer Group Pension Plan entered into a full buy-in contract with an insurer, which is designed to substantially match the Plans future benefit obligations with corresponding insurance cash flows. While the buy-in does not constitute a settlement event under ASC 715 and therefore did not result in …

"14. Segmental Information We classify our operations into business segments based primarily on shared economic characteristics, including the nature of the products and services; the production processes; the type or class of customer; the methods used to distribute products or provide services; and the nature of the regulatory environment. For the Second Quarter ended June 28, 2026, the Company operated four business units, which comprise three reportable segments within continuing operations: Gas Cylinders, Elektron and Superform. Luxfer Gas Cylinders forms the Gas Cylinders segment, Luxfer MEL Technologies and Luxfer Magtech aggregate into the Elektron segment, and Superform forms the Superform segment. Prior to its disposal on July 2, 2025, the Luxfer Graphic Arts business was reported as a separate business unit and reportable segment following its disaggregation from the Elektron segment as of December 31, 2023. As a result, Graphic Arts is included within the prior year comparative information. During the Second Quarter of 2026, the Company ceased actively marketing the Superform business for sale and determined that the business no longer met the criteria for classification as held-for-sale. As the Company is no longer pursuing the disposal of Superform, the business is no longer presented as a discontinued operation and has been reclassified into continuing operations as a separate reportable segment. Prior period comparative information has been restated to reflect …
