1 The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular period may not equal the earnings-per-share amount in total.

2 The loss per share for discontinued operations in the First Quarter of 2022 has not been diluted, since the incremental shares included in the weighted-average number of shares outstanding would have been anti-dilutive.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited condensed consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP).

Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning.

In the opinion of management, our financial statements reflect all adjustments, which are only of a normal recurring nature, necessary for the fair statement of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements.

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The First Quarter 2023, ended on April 2, 2023, and the First Quarter 2022, ended on March 27, 2022.

Accounting standards issued but not yet effective

None that are expected to be material to the Company.

2.    Earnings per share

Basic earnings per share are computed by dividing net income or loss for the period by the weighted-average number of ordinary shares outstanding, net of treasury shares and shares held in ESOP. Diluted earnings per share are computed by dividing net income or loss for the period by the weighted average number of ordinary shares outstanding and the dilutive ordinary shares equivalents.

Basic and diluted earnings per share were calculated as follows:

	First Quarter
In millions except share and per-share data	2023		2022
Basic earnings:
Net income from continuing operations	$	0.5	$	7.7
Net income / (loss) from discontinued operations	—		(0.1)
Net income	$	0.5	$	7.6
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	26,921,010		27,490,741
Dilutive effect of potential common stock	150,484		205,377
For diluted earnings per share	27,071,494		27,696,118
Earnings / (loss) per share using weighted average number of ordinary shares outstanding(1):
Basic earnings per ordinary share for continuing operations	$	0.02	$	0.28
Basic earnings / (loss) per ordinary share for discontinued operations	—		—
Basic earnings per ordinary share	$	0.02	$	0.28
Diluted earnings per ordinary share for continuing operations	$	0.02	$	0.28
Diluted earnings / (loss) per ordinary share for discontinued operations	—		—
Diluted earnings per ordinary share	$	0.02	$	0.28

(1) The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular period may not equal the earnings-per-share amount in total

In the first quarter of 2022, basic average shares outstanding and diluted average shares outstanding were the same for discontinued operations because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss from discontinued operations.

3.    Net Sales

Disaggregated sales disclosures for the quarters ended April 2, 2023, and March 27, 2022, are included below and in Note 13, Segmental Information.

	First Quarter
	2023						2022

	$	41.5	$	59.8	$	101.3	$	42.4	$	54.6	$	97.0

The Company’s performance obligations are satisfied at a point in time. With the classification of our Superform business as discontinued operations, none of the Company's revenue from continuing operations is satisfied over time. As a result, the Company's contract receivables, contract assets and contract liabilities are included within current assets and liabilities held-for-sale.

4.    Restructuring

The $0.3 million (2021: $1.4 million) restructuring charges in the first quarter of 2023, predominantly relates to costs incurred in streamlining our North American Gas Cylinder business. The $1.4 million restructuring charge in 2022 relates solely to costs associated with the closure of Luxfer Gas Cylinders France, which ceased operations in 2019.

Restructuring-related costs by reportable segment were as follows:

	First Quarter

Loan notes due and shelf facility

The Note Purchase Agreement and Private Shelf Agreement requires us to maintain compliance with a minimum interest coverage ratio and a leverage ratio. We have been in compliance with the covenants under the Note Purchase and Private Shelf Agreement throughout all of the quarterly measurement dates from and including September 30, 2014, to April 2, 2023.

The Loan Notes due 2023 and 2026, the Shelf Facility and the Note Purchase and Private Shelf Agreement are governed by the law of the State of New York.

During the first quarter of 2023, we drew down net $9.9 million on the Revolving Credit Facility and the balance outstanding at April 2, 2023, was $42.2 million, and at December 31, 2022, was $31.9 million, with $82.8 million undrawn at April 2, 2023.

We have been in compliance with the covenants under the Senior Facilities Agreement throughout all of the quarterly measurement dates to April 2, 2023.

9.    Discontinued Operations

Our Superform aluminum superplastic forming business operating in the U.S. was historically included in the Gas Cylinders segment. As a result of our decision to exit non-strategic aluminum product lines, we have reflected the results of operations of this business as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented. We expect the sale of our Superform business to occur in 2023.

The assets and liabilities of the Superform business have been presented within assets held-for-sale and liabilities held-for-sale in the consolidated balance sheets for 2023 and 2022.

Results of discontinued operations in the first quarter of 2023 and 2022 were as follows:

Also included within assets held-for-sale in 2023 and 2022 are land and buildings valued at $1.2 million, within our Elektron Segment.

There was no depreciation and amortization, capital expenditures and significant non-cash items.

Cash balances are swept into the treasury entities at the end of each day, these sweeps are recorded within operating cash flows in the statements of cash flows.

10.    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 on continuing operations for the Quarter ended April 2, 2023, was 116.0%, compared to 24.5% for the Quarter ended March 27, 2022. The rate was impacted by non-deductible expenses and a deferred tax credit, primarily in relation to the U.S. pension buyout.

11.    Share Plans

Total share-based compensation expense for the quarters ended April 2, 2023 and March 27, 2022 was as follows:

	First Quarter
In millions	2023		2022
Total share-based compensation charges	$	0.6	$	0.2

In March 2023, we issued our annual share-based compensation grants under the Luxfer Holdings PLC Long-Term Umbrella Incentive Plan. The total number of awards issued was approximately 126,600 and the weighted average fair value of options granted in 2023 was estimated to be $17.94 per share.

Also in March 2023, approximately 10,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2020 to December 31, 2022. 50% of these awards vested immediately upon grant, with the remaining 50% vesting in March 2024.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2023 and the year-ended December 31, 2022:

	First Quarter	Year ended December 31,
	2023	2022
Dividend yield (%)	2.75 - 3.41	2.75 - 3.41
Expected volatility range (%)	36.11 - 49.43	36.11 - 49.43
Risk-free interest rate (%)	1.28 - 2.99	1.28 - 2.99
Expected life of share options range (years)	0.50 - 4.00	0.50 - 4.00
Forfeiture rate (%)	5.00	5.00
Weighted average exercise price ($)	$1.00	$1.00
Model used	Black-Scholes & Monte-Carlo	Black-Scholes & Monte-Carlo

The expected life of the share options is based on historical data and current expectations, and is not necessarily indicative of exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

13.    Segmental Information

We classify our operations into two core business segments, Gas Cylinders and Elektron, based primarily on shared economic characteristics for the nature of the products and services; the nature of the production processes; the type or class of customer for their products and services; the methods used to distribute their products or provide their services; and the nature of the regulatory environment. The Company has four identified business units, which aggregate into the two reportable segments. Luxfer Gas Cylinders forms the Gas Cylinders segment, and Luxfer MEL Technologies, Luxfer Magtech and Luxfer Graphic Arts aggregate into the Elektron segment. The Superform business unit used to aggregate into the Gas Cylinders segment, but is now recognized as discontinued operations. A summary of the operations of the segments is provided below:

Gas Cylinders segment

Our Gas Cylinders segment manufactures and markets specialized products using composites and aluminum, including pressurized cylinders for use in various applications including self-contained breathing apparatus (SCBA) for firefighters, containment of oxygen and other medical gases for healthcare, alternative fuel vehicles, and general industrial.

Elektron segment                                                Our Elektron segment focuses on specialty materials based primarily on magnesium and zirconium, with key product lines including advanced lightweight magnesium alloys with a variety of uses across a variety of industries; magnesium powders for use in countermeasure flares, as well as heater meals; photoengraving plates for graphic arts; and high-performance zirconium-based materials and oxides used as catalysts and in the manufacture of advanced ceramics, fiber-optic fuel cells, and many other performance products.

Other

Other primarily represents unallocated corporate expense and includes non-service related defined benefit pension cost / credit.

Management monitors the operating results of its reportable segments separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated by the chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments as the CEO, using adjusted EBITDA, which we defined as segment income and are based on operating income adjusted for share based compensation charges; loss on disposal of property, plant and equipment; restructuring charges; impairment charges; acquisition and disposal related gains and costs; other charges; depreciation and amortization; and unwind of the discount on deferred consideration.

Unallocated assets and liabilities include those which are held on behalf of the Company and cannot be allocated to a segment, such as taxation, investments, cash, retirement benefits obligations, bank and other loans and holding company assets and liabilities.

Financial information by reportable segment for the Quarters ended April 2, 2023, and March 27, 2022, is included in the following summary:

14.     Commitments and Contingencies

Committed and uncommitted banking facilities

The Company had committed banking facilities of $125.0 million at April 2, 2023 and $100.0 million December 31, 2022. Of these committed facilities, $42.2 million was drawn at April 2, 2023 and $10.8 million at December 31, 2022. The Company also had an additional $25.0 million of uncommitted facilities through an accordion provision at April 2, 2023 and $50.0 million at December 31, 2022.

	Uncommitted Facilities

Overdraft	4.0		—		4.0		—
	$	6.6	$	1.7	$	6.6	$	1.7

Contingencies

In November 2018, an alleged explosion occurred at a third-party waste disposal and treatment site in Grand View, Idaho, reportedly causing property damage, personal injury, and one fatality. We contracted with a service company for removal and disposal of certain waste resulting from the magnesium powder manufacturing operations at the Reade facility in Manchester, New Jersey. We believe this service company, in turn, contracted with the third-party disposal company, at whose facility the explosion occurred, for treatment and disposal of the waste. In November 2020, we were named as a defendant in three lawsuits in relation to the incident – one by the third-party disposal company, one by the estate of the decedent, and one by an injured employee of the third-party disposal company. We believe that we are not liable for the incident, have asserted such, and continue to fully defend the Company against these lawsuits. Therefore, we do not currently expect any eventual outcome in these matters to have a material impact on the Company's financial position or results of operations.

15. Pension Settlement

In the first quarter of 2023, there was a $9.2 million charge in relation to the sale of the U.S. pension plan liability to an insurer, which included $2.3 million cash and $6.9 million in relation to the derecognition of the U.S. pension liability and reallocation of accumulated actuarial losses from other comprehensive income. This was partially offset by a $0.3 million (2022: $0.4 million) defined benefit credit on the U.K. pension plan, consistent with the prior year.

16. Subsequent Events

No material events.

About Luxfer

Luxfer is a global industrial company innovating niche applications in materials engineering. Luxfer focuses on value creation by using its broad array of technical know-how and proprietary technologies to help create a safe, clean and energy-efficient world. Luxfer's high-performance materials, components and high-pressure gas containment devices are used in defense, first response and healthcare, transportation and general industrial applications.

Key trends and uncertainties regarding our existing business

Margin pressure resulting from supply chain challenges

We have, and continue to experience supply chain challenges characterized by significant increases in material cost inflation on key inputs (including magnesium, aluminum and carbon fiber), labor availability issues and energy and transport cost increases. Additionally, force majeure still remains in place for our key supplier of U.S. sourced magnesium, with supply not expected to recommence until at least Q3 of 2023. However, we have been successful in securing alternative sources of supply outside of the U.S.

In the majority of cases we are able to pass through inflationary costs to our customers, although we are still constrained by contracts, particularly in the Gas Cylinders segment, the longest running of which is not subject to renewal until mid-2024. Currently, our expectation is that the impact of material availability / inflation, energy cost inflation and labor and transport constraints will continue throughout 2023; but that we will be able to source sufficient material to meet demand and that in the majority of cases we expect to be able to pass on cost increases. However the outlook remains highly uncertain with both the size and timing of future cost increases difficult to predict.

Operating objectives and trends

In 2023, we expect the following operating objectives and trends to impact our business:

•Continuing high activity on revenue growth initiatives with particular focus on increasing volumes;

•Actions to ensure continuity of supply of critical materials and services while safeguarding margins;

•Execution of productivity improvements and increases in selling prices to mitigate and pass through current cost pressure;

•Further improvements in ESG standing through investment in new projects;

•Focus on recruiting, developing and maintaining talent, through our new leadership development programs, while driving a high-performance culture; and

•Continued emphasis on operating cash generation and maintaining strong working capital performance.

CONSOLIDATED RESULTS OF OPERATIONS

The consolidated results of operations for the First Quarter of 2023 and 2022 of Luxfer were as follows:

Net sales

Adjusting for foreign exchange headwinds of $2.3 million, net sales have increased by 6.8% in the first of 2023 respectively. The passing through of material cost inflation, where not constrained by contract, accounted for approximately $11.1 million of the increase in consolidated net sales in the first quarter, of 2023 from 2022. Furthermore, there was a benefit in the quarter from:

•Increased sales of magnesium alloys, especially those used in aerospace applications;

•Higher demand for our zirconium products, particularly those used in auto-catalysis and pharmaceutical applications;

•Strong demand for our chemical detection and response kits; and

•Year-over-year growth in SCBA and medical cylinder sales.

These increases were partially offset by:

•Timing of sales for flameless ration heaters ("FRH") and Meals-Ready-to Eat products ("MRE");

•Decreased demand for photo-engraving plates;

•Lower sales of Solumag® due to destocking by customers in the Oil and Gas industry; and

•Alternative fuel cylinders being down on prior year due to timing of customer projects.

Gross profit

The 4.1 percentage point decrease in gross profit as a percentage of sales in the first quarter of 2023 from 2022 was primarily the result of the continued increased material and labor costs and other supply chain investments to overcome disruption, not fully covered by price increases, particularly in the Gas Cylinders Division.

Selling, general and administrative expenses ("SG&A")

SG&A costs as a percentage of sales in 2023 from 2022 has increased by 1.3 percentage points largely due to $1.1 million of legal costs expensed in the Elektron segment.

Research and development costs

Research and development costs as a percentage of sales decreased by 0.1 percentage points in the first quarter of 2023 relative to 2022 respectively, with the slight reduction due to the inflationary impact on sales.

Restructuring charges

The $0.3 million restructuring charge in the first quarter of 2023, predominantly relates to costs incurred in respect of cost savings initiatives affecting our North American Gas Cylinders business.

The $1.4 million restructuring charge in 2022 relates solely to costs associated with the closure of Luxfer Gas Cylinders France, which ceased operations in 2019.

Acquisition and disposal related costs

Acquisition related costs of $0.2 million in 2022 represents amounts incurred in relation to the acquisition of SCI.

Net interest expense

Net interest expense of $1.3 million in the first quarter of 2023 increased $0.5 million from $0.8 million in the first quarter 2022, due to combination of higher interest rates and increased drawings.

20

Defined benefit pension (charge) / credit

In the first quarter of 2023, there was a $9.2 million charge in relation to the sale of the U.S. pension plan liability to an insurer, which included $2.3 million cash and $6.9 million in relation to the derecognition of the U.S. pension liability and reallocation of accumulated actuarial losses from other comprehensive income. This was partially offset by a $0.3 million (2022: $0.4 million) defined benefit credit on the U.K. pension plan, consistent with the prior year.

Provision for income taxes

The movement in the statutory effective tax rate from 24.5% in 2022, to 116.1% in 2023, was primarily due to non-deductible expenses and deferred tax credit, predominantly in relation to the previously mentioned pension buyout. When stripping out the impact of this, as well as other less significant adjusting items, the adjusted effective tax rate has reduced slightly to 21.7% in 2023 from 22.0% in 2022, largely as a result of jurisdictional profit mix.

21

RECONCILIATION OF NON-GAAP FINANCIAL MEASURES TO GAAP MEASURES

The following table of non-GAAP summary financial data presents a reconciliation of net income to adjusted net income for the periods presented, being the most comparable GAAP measure. Management believes that adjusted net income, adjusted earnings per share, adjusted EBITA and adjusted EBITDA are key performance indicators (KPIs) used by the investment community and that such presentation will enhance an investor’s understanding of the Company's operational results. In addition, Luxfer's CEO and other senior management use these KPIs, among others, to evaluate business performance. However, investors should not consider adjusted net income and adjusted earnings per share in isolation as an alternative to net income and earnings per share when evaluating Luxfer's operating performance or measuring Luxfer's profitability.

SEGMENT RESULTS OF OPERATIONS

The summary that follows provides a discussion of the results of operations of each of our two reportable segments (Gas Cylinders and Elektron). Both segments comprise various product offerings that serve multiple end markets.

Adjusted EBITDA represents operating income adjusted for share based compensation charges; restructuring charges; acquisition and disposal related gains and costs; depreciation and amortization. A reconciliation to net income and taxes can be found in Note 13 to the condensed consolidated financial statements.

GAS CYLINDERS

The net sales and adjusted EBITDA for Gas Cylinders were as follows:

	First Quarter						% / point change
In millions	2023			2022			2023 v 2022
Net sales	$	41.5		$	42.4		(2.1)%
Adjusted EBITDA	2.5			2.7			(7.4)%
% of net sales	6.0		%	6.4		%	(0.4)

Net sales

The 2.1% decrease in Gas Cylinders sales in the first quarter of 2023 from 2022 was primarily the result of:

•Reduction in alternative fuel cylinder sales; and

•$1.5 million FX headwind.

These decreases have been partially offset by:

•Increased demand for SCBA cylinders; and

•Improved sales of medical oxygen cylinders.

Adjusted EBITDA

There was a 0.4 percentage point decrease in adjusted EBITDA for Gas Cylinders as a percentage of net sales in the first quarter of 2023 relative to 2022. Pricing increases have matched inflation as our ability to pass-through cost increases improved. Volume and mix reductions more than offset favorable foreign exchange impact.

23

ELEKTRON

The net sales and adjusted EBITDA for Elektron were as follows:

	First Quarter						% / point change
In millions	2023			2022			2023 v 2022
Net sales	$	59.8		$	54.6		9.5%
Adjusted EBITDA	8.8			13.4			(34.3)%
% of net sales	14.7		%	24.5		%	(9.8)

Net sales

The 9.5% increase in Elektron sales in the first quarter of 2023 from 2022 was primarily the result of:

•Increased sales of magnesium alloys, especially those used in aerospace applications;

•Higher demand for our zirconium products, particularly those used in auto-catalysis and pharmaceutical applications; and

•Strong demand for our chemical detection and response kits.

These increases were partially offset by:

•Timing of sales for flameless ration heaters ("FRH") and Meals-Ready-to Eat products ("MRE");

•Decreased demand for photo-engraving plates; and

•Destocking by customers in the Oil and Gas industry.

Net sales were also impacted by $0.8 million of FX headwinds.

Adjusted EBITDA

The 9.8 percentage point decrease in adjusted EBITDA for Elektron as a percentage of net sales in the first quarter of 2023 from 2022 was impacted by $1.1 million of legal costs recognized in the quarter, coupled with accelerated cost recovery in the first quarter of 2022 and lower sales in certain higher margin end markets in the first quarter of 2023.

LIQUIDITY AND CAPITAL RESOURCES

Our liquidity requirements arise primarily from obligations under our indebtedness, capital expenditures, acquisitions, the funding of working capital and the funding of hedging facilities to manage foreign exchange and commodity purchase price risks. We meet these requirements primarily through cash flows from operating activities, cash deposits and borrowings under the Revolving Credit Facility and accompanying ancillary hedging facilities and the Loan Notes due, 2023 and 2026. Our principal liquidity needs are:

•funding acquisitions, including deferred contingent consideration payments;

•capital expenditure requirements;

•payment of shareholder dividends;

•servicing interest on the Loan Notes, which is payable at each quarter end, in addition to interest and / or commitment fees on the Senior Facilities Agreement;

•working capital requirements, particularly in the short term as we aim to safeguard the business from supply chain constraints, as well as to achieve organic sales growth; and

•hedging facilities used to manage our foreign exchange risks.

From time to time, we consider acquisitions or investments in other businesses that we believe would be appropriate additions to our business.

We believe that, in the long term, cash generated from our operations will be adequate to meet our anticipated requirements for working capital, capital expenditures and interest payments on our indebtedness. In the short term, we believe we have sufficient credit facilities to cover any variation in our cash flow generation. However, any major repayments of indebtedness will be dependent on our ability to raise alternative financing or to realize substantial returns from operational sales. Also, our ability to expand operations through sales development and capital expenditures could be constrained by the availability of liquidity, which, in turn, could impact the profitability of our operations.

24

We have been in compliance with the covenants under the Loan Notes and the Senior Facilities Agreement throughout all of the quarterly measurement dates from and including September 30, 2011, to April 2 2023.

Luxfer conducts all of its operations through its subsidiaries, joint ventures and affiliates. Accordingly, Luxfer's main cash source is dividends from its subsidiaries. The ability of each subsidiary to make distributions depends on the funds that a subsidiary receives from its operations in excess of the funds necessary for its operations, obligations or other business plans. We have not historically experienced any material impediment to these distributions, and we do not expect any local legal or regulatory regimes to have any impact on our ability to meet our liquidity requirements in the future. In addition, since our subsidiaries are wholly-owned, our claims will generally rank junior to all other obligations of the subsidiaries. If our operating subsidiaries are unable to make distributions, our growth may slow, unless we are able to obtain additional debt or equity financing. In the event of a subsidiary's liquidation, there may not be assets sufficient for us to recoup our investment in the subsidiary.

Our ability to maintain or increase the generation of cash from our operations in the future will depend significantly on the competitiveness of and demand for our products, including our success in launching new products. Achieving such success is a key objective of our business strategy. Due to commercial, competitive and external economic factors, however, we cannot guarantee that we will generate sufficient cash flows from operations or that future working capital will be available in an amount sufficient to enable us to service our indebtedness or make necessary capital expenditures.

Cash Flows

Operating activities

Cash used by operating activities was $14.4 million for the first quarter of 2023 compared to $9.3 million in the first quarter of 2022. It was primarily related to net income from operating activities offset by significant increases in working capital related to inventory build to protect supply chain, and net of the following non-cash items: depreciation and amortization; share-based compensation charges; pension credit and net changes to assets and liabilities. In 2023, the Company also contributed $2.3 million in relation to the sale of the U.S. pension plan to an insurer.

Investing activities

Net cash used by investing activities was $2.0 million for the first quarter of 2023, compared to net cash used for investing activities of $1.0 million in 2022, as a result of increased capital expenditure in the quarter.

Financing activities

In the first quarter of 2023, net cash provided by financing activities was $5.3 million, compared to $21.4 million inflow in 2022. We made net drawdown on our banking facilities of $9.9 million (2022: $26.7 million drawdown) and dividend payments of $3.5 million (2022: $3.4 million), equating to $0.13 and $0.125 per ordinary share respectively. In addition, we paid out $0.3 million (2022: $0.4 million) in settling share based compensation and $0.8 million (2022: $1.5 million) in repurchasing our own shares as part of the share buyback program which equates to 48,000 shares (2022: 60,100 shares).

Capital Resources

Dividends

We paid year-to-date dividends in 2023 of $3.5 million (2022: $3.4 million year-to-date), or $0.13 per ordinary share (2021: $0.125).

Any payment of dividends is also subject to the provisions of the U.K. Companies Act, according to which dividends may only be paid out of profits available for distribution determined by reference to financial statements prepared in accordance with the Companies Act and U.K.-adopted Internatioanl Accounting Standards, which differ in some respects from GAAP. In the event that dividends are paid in the future, holders of the ordinary shares will be entitled to receive payments in U.S. dollars in respect of dividends on the underlying ordinary shares in accordance with the deposit agreement. Furthermore, because we are a holding company, any dividend payments would depend on cash flows from our subsidiaries.

25

Authorized shares

Our authorized share capital consists of 40.0 million ordinary shares with a par value of £0.50 per share.

Contractual obligations

The following summarizes our significant contractual obligations that impact our liquidity:

NEW ACCOUNTING STANDARDS

See Note 1 of the Notes to Condensed Consolidated Financial Statements for information pertaining to recently adopted accounting standards or accounting standards to be adopted in the future.

CRITICAL ACCOUNTING POLICIES

We have adopted various accounting policies to prepare the consolidated financial statements in accordance with GAAP. Certain of our accounting policies require the application of significant judgment by management in selecting the appropriate assumptions for calculating financial estimates. In our 2022 Annual Report on Form 10-K, filed with the SEC on March 1, 2023, we identified the critical accounting policies which affect our more significant estimates and assumptions used in preparing our consolidated financial statements.

Item 3.        Quantitative and qualitative disclosures about market risk

There have been no material changes in our market risk during the first quarter ended April 2, 2023. For additional information, refer to Item 7A of our 2022 Annual Report on Form 10-K, filed with the SEC on March 1, 2023.

Item 4.        Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of disclosure controls and procedures designed to provide reasonable assurance as to the reliability of our published financial statements and other disclosures included in this report. Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the quarter ended April 2, 2023, pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934 (the “Exchange Act”). Based upon their evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that our disclosure controls and procedures were effective, at a reasonable assurance level, as of the quarter ended April 2, 2023, to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms, and to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosures.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended April 2, 2023, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

27

PART II - OTHER INFORMATION

Item 1.        Legal Proceedings

The Company is a defendant in various lawsuits and is subject to various claims that arise in the normal course of business, the most significant of which are summarized in Note 14 (commitments and contingencies) to the consolidated financial statements in ITEM 1. In the opinion of management, the likelihood that the ultimate disposition of these matters will have a material adverse impact is remote.

Item 1A.    Risk Factors

There have been no material changes from the risk factors previously disclosed in Item 1A. of our 2022 Annual Report on Form 10-K filed with the SEC on March 1, 2023.

Item 2.        Unregistered Sales of Equity Securities and Use of Proceeds

Basis of Presentation and Responsibility for interim Financial Statements

Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited condensed consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP).

Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning.

In the opinion of management, our financial statements reflect all adjustments, which are only of a normal recurring nature, necessary for the fair statement of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements.

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The First Quarter 2023, ended on April 2, 2023, and the First Quarter 2022, ended on March 27, 2022.

Earnings per share

Earnings Per Share [Abstract]

Earnings per share

Earnings per share

Basic earnings per share are computed by dividing net income or loss for the period by the weighted-average number of ordinary shares outstanding, net of treasury shares and shares held in ESOP. Diluted earnings per share are computed by dividing net income or loss for the period by the weighted average number of ordinary shares outstanding and the dilutive ordinary shares equivalents.

Basic and diluted earnings per share were calculated as follows:

	First Quarter
In millions except share and per-share data	2023		2022
Basic earnings:
Net income from continuing operations	$	0.5	$	7.7
Net income / (loss) from discontinued operations	—		(0.1)
Net income	$	0.5	$	7.6
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	26,921,010		27,490,741
Dilutive effect of potential common stock	150,484		205,377
For diluted earnings per share	27,071,494		27,696,118
Earnings / (loss) per share using weighted average number of ordinary shares outstanding(1):
Basic earnings per ordinary share for continuing operations	$	0.02	$	0.28
Basic earnings / (loss) per ordinary share for discontinued operations	—		—
Basic earnings per ordinary share	$	0.02	$	0.28
Diluted earnings per ordinary share for continuing operations	$	0.02	$	0.28
Diluted earnings / (loss) per ordinary share for discontinued operations	—		—
Diluted earnings per ordinary share	$	0.02	$	0.28

(1) The calculation of earnings per share is performed separately for continuing and discontinued operations. As a result, the sum of the two in any particular period may not equal the earnings-per-share amount in total

In the first quarter of 2022, basic average shares outstanding and diluted average shares outstanding were the same for discontinued operations because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss from discontinued operations.

Discontinued Operations

Our Superform aluminum superplastic forming business operating in the U.S. was historically included in the Gas Cylinders segment. As a result of our decision to exit non-strategic aluminum product lines, we have reflected the results of operations of this business as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented. We expect the sale of our Superform business to occur in 2023.

The assets and liabilities of the Superform business have been presented within assets held-for-sale and liabilities held-for-sale in the consolidated balance sheets for 2023 and 2022.

Results of discontinued operations in the first quarter of 2023 and 2022 were as follows:

Income Taxes

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 on continuing operations for the Quarter ended April 2, 2023, was 116.0%, compared to 24.5% for the Quarter ended March 27, 2022. The rate was impacted by non-deductible expenses and a deferred tax credit, primarily in relation to the U.S. pension buyout.

	First Quarter
In millions	2023		2022
Total share-based compensation charges	$	0.6	$	0.2

In March 2023, we issued our annual share-based compensation grants under the Luxfer Holdings PLC Long-Term Umbrella Incentive Plan. The total number of awards issued was approximately 126,600 and the weighted average fair value of options granted in 2023 was estimated to be $17.94 per share.

Also in March 2023, approximately 10,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2020 to December 31, 2022. 50% of these awards vested immediately upon grant, with the remaining 50% vesting in March 2024.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2023 and the year-ended December 31, 2022:

	First Quarter	Year ended December 31,
	2023	2022
Dividend yield (%)	2.75 - 3.41	2.75 - 3.41
Expected volatility range (%)	36.11 - 49.43	36.11 - 49.43
Risk-free interest rate (%)	1.28 - 2.99	1.28 - 2.99
Expected life of share options range (years)	0.50 - 4.00	0.50 - 4.00
Forfeiture rate (%)	5.00	5.00
Weighted average exercise price ($)	$1.00	$1.00
Model used	Black-Scholes & Monte-Carlo	Black-Scholes & Monte-Carlo

The expected life of the share options is based on historical data and current expectations, and is not necessarily indicative of exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

Segment Reporting [Abstract]

Segmental Information

Segmental Information

We classify our operations into two core business segments, Gas Cylinders and Elektron, based primarily on shared economic characteristics for the nature of the products and services; the nature of the production processes; the type or class of customer for their products and services; the methods used to distribute their products or provide their services; and the nature of the regulatory environment. The Company has four identified business units, which aggregate into the two reportable segments. Luxfer Gas Cylinders forms the Gas Cylinders segment, and Luxfer MEL Technologies, Luxfer Magtech and Luxfer Graphic Arts aggregate into the Elektron segment. The Superform business unit used to aggregate into the Gas Cylinders segment, but is now recognized as discontinued operations. A summary of the operations of the segments is provided below:

Gas Cylinders segment

Our Gas Cylinders segment manufactures and markets specialized products using composites and aluminum, including pressurized cylinders for use in various applications including self-contained breathing apparatus (SCBA) for firefighters, containment of oxygen and other medical gases for healthcare, alternative fuel vehicles, and general industrial.

Elektron segment                                                Our Elektron segment focuses on specialty materials based primarily on magnesium and zirconium, with key product lines including advanced lightweight magnesium alloys with a variety of uses across a variety of industries; magnesium powders for use in countermeasure flares, as well as heater meals; photoengraving plates for graphic arts; and high-performance zirconium-based materials and oxides used as catalysts and in the manufacture of advanced ceramics, fiber-optic fuel cells, and many other performance products.

Other

Other primarily represents unallocated corporate expense and includes non-service related defined benefit pension cost / credit.

Management monitors the operating results of its reportable segments separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated by the chief operating decision maker, who is responsible for allocating resources and assessing performance of the operating segments as the CEO, using adjusted EBITDA, which we defined as segment income and are based on operating income adjusted for share based compensation charges; loss on disposal of property, plant and equipment; restructuring charges; impairment charges; acquisition and disposal related gains and costs; other charges; depreciation and amortization; and unwind of the discount on deferred consideration.

Unallocated assets and liabilities include those which are held on behalf of the Company and cannot be allocated to a segment, such as taxation, investments, cash, retirement benefits obligations, bank and other loans and holding company assets and liabilities.

Financial information by reportable segment for the Quarters ended April 2, 2023, and March 27, 2022, is included in the following summary:

In November 2018, an alleged explosion occurred at a third-party waste disposal and treatment site in Grand View, Idaho, reportedly causing property damage, personal injury, and one fatality. We contracted with a service company for removal and disposal of certain waste resulting from the magnesium powder manufacturing operations at the Reade facility in Manchester, New Jersey. We believe this service company, in turn, contracted with the third-party disposal company, at whose facility the explosion occurred, for treatment and disposal of the waste. In November 2020, we were named as a defendant in three lawsuits in relation to the incident – one by the third-party disposal company, one by the estate of the decedent, and one by an injured employee of the third-party disposal company. We believe that we are not liable for the incident, have asserted such, and continue to fully defend the Company against these lawsuits. Therefore, we do not currently expect any eventual outcome in these matters to have a material impact on the Company's financial position or results of operations.

Basis of presentation

Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited condensed consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP).

Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning.

In the opinion of management, our financial statements reflect all adjustments, which are only of a normal recurring nature, necessary for the fair statement of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements.

Fiscal year

Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The First Quarter 2023, ended on April 2, 2023, and the First Quarter 2022, ended on March 27, 2022.
