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 Second Quarter of 2022 and 2021 and year-to-date 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, 2021. 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 Second Quarter 2022, ended on June 26, 2022, and the Second Quarter 2021, ended on June 27, 2021.

Accounting standards issued but not yet effective

None that will 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:

	Second Quarter				Year-to-date
In millions except share and per-share data	2022		2021		2022		2021
Basic earnings:
Net income from continuing operations	$	9.6	$	11.9	$	17.3	$	20.5
Net (loss) / income from discontinued operations	(0.3)		(0.9)		(0.4)		5.0
Net income	$	9.3	$	11.0	$	16.9	$	25.5
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,428,579		27,771,983		27,458,980		27,717,025
Dilutive effect of potential common stock	274,638		359,802		261,085		378,763
For diluted earnings per share	27,703,217		28,131,785		27,720,065		28,095,788
Earnings / (loss) per share using weighted average number of ordinary shares outstanding(1):
Basic earnings per ordinary share for continuing operations	$	0.35	$	0.43	$	0.63	$	0.74
Basic (loss) / earnings per ordinary share for discontinued operations	(0.01)		(0.03)		(0.01)		0.18
Basic earnings per ordinary share	$	0.34	$	0.40	$	0.62	$	0.92
Diluted earnings per ordinary share for continuing operations	$	0.35	$	0.42	$	0.62	$	0.73
Diluted (loss) / earnings per ordinary share for discontinued operations	(0.01)		(0.03)		(0.01)		0.18
Diluted earnings per ordinary share	$	0.34	$	0.39	$	0.61	$	0.91

(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 second quarter of 2022 and 2021 and year-to-date 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 quarter and year-to-date ended June 26, 2022, and June 27, 2021, are included below and in Note 14, Segmental Information.

	Second Quarter
	2022						2021

	$	88.5	$	118.0	$	206.5	$	82.7	$	101.5	$	184.2

The Company’s performance obligations are satisfied at a point in time. With the reclassification 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: $0.2 million) and $1.7 million restructuring charges (2021: $1.6 million) in the second quarter and first half of 2022, respectively, included $0.1 million (2021: $0.2 million) and $1.5 million (2021: $0.7 million), respectively, of further costs associated with the announced closure of Luxfer Gas Cylinders France, and was largely legal and professional fees. In addition $0.2 million of costs were incurred in the second quarter of 2022 relating to one-time employee termination benefits in the Elektron division in relation to the consolidation of production facilities in the Magnesium Powders operations incurred in the second quarter of 2022.

The first half of 2021 also includes $0.9 million primarily of one-time employee termination benefits in the Elektron division, largely in relation to the divestiture of our small Luxfer Magtech production facility in Ontario, Canada.

Restructuring-related costs by reportable segment were as follows:

	Second Quarter				Year-to-date
In millions	2022		2021		2022		2021

5.    Acquisition and disposal related costs

On March 15, 2021 the Company completed the acquisition of the Structural Composites Industries LLC (SCI) business of Worthington Industries, Inc., based in Pomona, California, for $19.3 million cash consideration. The acquisition of SCI strengthens Luxfer’s composite cylinder offerings and aligns with recent investment to enhance our alternative fuel capabilities to capitalize on the growing compressed natural gas (CNG) and hydrogen opportunities.

Acquisition-related costs of $0.3 million in the first half of 2022 and $0.9 million in the first half of 2021 represent transitional costs and professional fees incurred in relation to the SCI acquisition.

6.    Other charges

There were no other charges in the first half of 2022.

10.    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 2022.

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 2022 and 2021.

In 2021, our Superform U.K. business was also disclosed within assets and liabilities held-for-sale. The business was sold in September 2021.

Results of discontinued operations in the first half of 2022 and 2021 were as follows:

In the Second Quarter of 2021, there was a $0.4 million working capital adjustment, reducing the purchase price to $20.6 million and the gain on disposal to $7.1 million.

10.    Discontinued Operations (continued)

The assets and liabilities classified as held-for-sale related to discontinued operations were as follows:

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.

11.    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 first half ended June 26, 2022, was 22.1%, compared to 7.7% for the 26-week period ended June 27, 2021. The 2021 rate was impacted by a $2.8 million deferred tax credit as a result of the enacted increase in the U.K. tax rate from 19% to 25% from April 2023.

12.    Share Plans

Total share-based compensation expense for the quarters ended June 26, 2022, and June 27, 2021, was as follows:

	Second Quarter				Year-to-date
In millions	2022		2021		2022		2021
Total share-based compensation charges	$	0.7	$	0.9	$	0.9	$	1.4

In March 2022, 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 167,400 and the weighted average fair value of options granted in 2022 was estimated to be $17.82 per share.

Also in March 2022, approximately 17,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2019 to December 31, 2021. 50% of these awards vested immediately upon grant, with the remaining 50% vesting in March 2023.

In June 2022, we issued our annual share-based compensation grants under the Luxfer Holdings PLC Non-Executive Directors' Equity Incentive Plan. The total number of awards issued was 26,295 and the weighted-average fair value of options granted was estimated to be $15.50 per share.

The following table illustrates the assumptions used in deriving the fair value of share options granted during 2022 and the year-ended December 31, 2021:

	2022	2021
Dividend yield (%)	2.27	2.27
Expected volatility range (%)	42.80 - 59.03	42.80 - 59.03
Risk-free interest rate (%)	0.04 - 0.24	0.04 - 0.24
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.

14.    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 EBITA(1) and 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.

1 Adjusted EBITA is adjusted EBITDA less depreciation

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 Second Quarter and year-to-date ended June 26, 2022, and June 27, 2021, is included in the following summary:

15.     Commitments and Contingencies

Committed and uncommitted banking facilities

The Company had committed banking facilities of $100.0 million at June 26, 2022, and December 31, 2021. Of these committed facilities, $26.8 million was drawn at June 26, 2022 and $10.8 million at December 31, 2021. The Company also had an additional $50.0 million of uncommitted facilities through an accordion provision.

The Company also has two separate (uncommitted) bonding facilities for bank guarantees, one denominated in GBP sterling of £0.5 million (2022: $0.6 million, 2021: $0.9 million), and one denominated in USD of $0.9 million (2021: $1.5 million). Of that dominated in GBP, £0.1 million ($0.1 million) and £0.1 million ($0.2 million) was utilized at June 26, 2022, and December 31, 2021, respectively. Of that denominated in USD, $0.9 million was utilized at June 26, 2022, and December 31, 2021, respectively.

The Company also has a $4.0 million separate overdraft facility of which none was drawn at June 26, 2022 and at December 31, 2021.

Contingencies

In November 2018, an explosion occurred at a third-party waste disposal and treatment site in Boise,

Idaho, reportedly causing property damage, personal injury, and one fatality. We had contracted with a service

company for removal and disposal of certain waste resulting from the magnesium powder manufacturing

operations at the Reade facility in Lakehurst, New Jersey. We believe this service company, in turn, apparently

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 do not believe that we are liable for the incident, have asserted such, and, therefore, do not currently expect this matter to have a material impact on the Company’s financial position or results of operations.

16. Subsequent Events

No material events.

Update on ongoing challenging global macro environment and related impact on supply chain disruption

Demand from most end-markets we serve has continued to improve following the adverse impact of COVID-19

on volumes, notably in 2020. This sharp recovery in demand across the global macro environment has resulted

in 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, in the prior year we were faced with two critical suppliers of magnesium and zirconium

respectively declaring force majeure, of which the former remains in place. The continuing conflict in Ukraine

which has resulted in punitive sanctions against the Russian Federation has further exacerbated the availability

and price of certain raw materials and energy supplies. In response to the supply chain disruption, we have been

successful in securing alternative sources of supply for key material inputs affected by force majeure.

Furthermore, in the majority of cases, we are able to pass through inflation to our customers. Currently, our

expectation is that the impact of material availability / inflation and energy cost inflation and labor and transport

constraints will continue into at least the second half of 2022; 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.

Impact of conflict in Ukraine

The Russian invasion of Ukraine and ongoing military conflict which commenced on February 24, 2022, has

resulted in massive displacement of the Ukrainian population and huge disruption to its economy. Wide-ranging

sanctions have been imposed on the Russian Federation by the international community, targeting individuals,

banks, businesses, funds transfers and imports and exports and are expected to have a significant adverse

impact on Russia's economy as well as on international businesses active in the region. The impact on Luxfer is

not expected to be significant as we have no direct operations in the region, and our sales to Russia and Ukraine

combined typically represent less than one percent of total revenue by destination. Furthermore, neither country

is a critical supplier of our raw material needs, and while Russia is a major global exporter of magnesium, we are

able to source the metal from various alternative locations, including China, Israel, Turkey and the United States.

Operating objectives and trends

In 2022, we expect the following operating objectives and trends to impact our business:

•Organic growth initiatives with particular focus on revenue from new products;

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

•Proactive response on health and well-being of employees, including continuous improvement on safety;

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

•Continued focus on recruiting and developing talent and driving a high-performance culture; and

•Continued focus on operating cash generation leveraging our recent years' of restructuring activity and targeting strong working capital performance.

Net sales

Adjusting for FX headwinds of $3.8 million and $5.0 million, net sales have increased by 15% and 15.2% in the second quarter and first half of 2022 respectively. The passing through of material cost inflation, where not constrained by contract, accounted for approximately 13.1% and 12.2% increase in consolidated net sales in the second quarter and first half, respectively, of 2022 from 2021. Furthermore, there was a benefit from:

•Growth in sales of magnesium powders used in both military flares and commercial use;

•Increased demand for composite cylinders used in aerospace and medical applications;

•Improved sales of our zirconium products especially in industrial applications; and

•Increased demand for magnesium photo-engraving plates.

These increases were partially offset by:

•Unfavorable foreign exchange variances of $3.8 million in the quarter and $5.0 million in the first half;

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

•Decline in sales of lower margin aluminum cylinders; and

•Reduction in alternative fuel cylinders.

Gross profit

The 2.7 and 3.5 percentage point decrease in gross profit as a percentage of sales in the second quarter and first half, respectively of 2022 from 2021 was primarily the result of increased material and labor costs and other supply chain investments to overcome disruption, not fully covered by price increases.

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

SG&A costs as a percentage of sales in 2022 from 2021 has decreased by 2.3 percentage points and 1.8 percentage points in the quarter and first half respectively, largely due to the impact of price increases on revenue, as well as cost reduction programs effected in the prior year.

Research and development costs

Research and development cost as a percentage of sales increased by 0.3 percentage points in the second quarter and first half of 2022 relative to 2021 respectively, as activity levels picked up as we recovered from the COVID-19 economic downturn and increased investment to achieve organic growth.

Restructuring charges

The $0.3 million and $1.7 million restructuring charge in the second quarter and first half of 2022 includes $0.2 million in the second quarter relating to one-time employee termination benefits in the Elektron division in relation to the consolidation of production facilities in the Magnesium Powders operations. The remaining $0.1 million and $1.4 million for the second quarter and first half respectively, relates to costs associated with the closure of Luxfer Gas Cylinders France, which ceased operations in 2019.

The $0.2 million and $1.6 million restructuring charge in the second quarter and first half of 2021 included $0.2 million and $0.7 million respectively of further costs associated with the announced closure of Luxfer Gas Cylinders France, and was largely legal and professional fees. The first half of 2021 also includes $0.9 million of one-time employee termination benefits in the Elektron division, largely in relation to the planned divestiture of our small Elektron production facility in Ontario, Canada.

Acquisition and disposal related costs

Net costs of $0.1 million and $0.3 million incurred in the second quarter and first half of 2022 respectively and (0.7) and (0.9) in the second quarter and first half of 2021 respectively, represents amounts incurred in relation to the acquisition of Structural Composites Industries.

23

Other charges

Other charges in the during 2021 relates to the settlement of a class action lawsuit in the Gas Cylinders segment in relation to an alleged historic violation of the Californian Labor Code, concerning an Human Resources administration matter.

Net interest expense

Net interest expense of $0.9 million in the second quarter of 2022 increased marginally from $0.8 million in the second quarter 2021,due to combination of increased interest rates and higher drawings . Interest expense of $1.7 million in the first half of 2022 was inline with the $1.6 million in the first half 2021.

Defined benefit pension credit

The $0.3 million and $0.5 million decrease in defined benefit pension credit to $0.3 million and $0.7 million in the second quarter and first half of 2022 from $0.6 million and $1.2 million in 2021 is primarily due to the combined effect on the U.K. plan of lower projected asset returns and a higher inflation projection.

Provision for income taxes

The movement in the statutory effective tax rate from 7.7% in 2021, to 22.1% in 2022, was primarily due to the impact of the enacted tax rate change in the U.K. in 2021, which is due to rise from 19% to 25% in April 2023. The subsequent increase in the value of deferred tax assets related to our defined benefit pension plan has resulted in a credit of $2.2 million recorded in our tax charge in the second quarter of 2021. When stripping out the impact of this, as well as other less significant adjusting items, the adjusted effective tax rate has increased to 22.2% in 2022 from 20.1% in 2021, largely as a result of jurisdictional profit mix.

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; gain on disposal of property, plant and equipment, restructuring charges; acquisition and disposal related gains and costs; other charges; depreciation and amortization. A reconciliation to net income and taxes can be found in Note 14 to the condensed consolidated financial statements.

GAS CYLINDERS

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

	Second Quarter						% / point change	Year-to-date						% / point change
In millions	2022			2021			2022 v 2021	2022			2021			2022 v 2021

% of net sales	8.0		%	11.4		%	(3.4)	7.2		%	13.7		%	(6.5)

Net sales

The 0.9% decrease in Gas Cylinders sales in the second quarter of 2022 from 2021 was primarily the result of:

•Decline in sales of aluminum products;

•Reduction in alternative fuel cylinder sales; and

•$2.0 million FX headwind.

These declines were partially offset by increased demand for composite cylinders used in aerospace and medical applications.

The first half of 2022 has benefited from $7.1 million of sales due to the acquisition of SCI at the end of the first quarter of 2021, which has positively impacted sales of cylinders used in aerospace and alternative fuels ("AF") applications.

Adjusted EBITDA

The 3.4 percentage point and 6.5 percentage point decrease in adjusted EBITDA for Gas Cylinders as a percentage of net sales in the second quarter and first half of 2022 relative to 2021 was primarily the result of losses incurred by the acquired SCI business and supply chain inflation not fully covered by price rises.

26

ELEKTRON

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

	Second Quarter						% / point change	Year-to-date						% / point change
In millions	2022			2021			2022 v 2021	2022			2021			2022 v 2021
Net sales	$	63.4		$	52.5		20.8%	$	118.0		$	101.5		16.3%
Adjusted EBITDA	13.2			12.0			10.0%	26.6			23.7			12.2%
% of net sales	20.8		%	22.9		%	(2.1)	22.5		%	23.3		%	(0.8)

Net sales

The 20.8% and 16.3% increase in Elektron sales in the second quarter and first half, respectively, of 2022 from 2021 was primarily the result of:

•Increased sales of magnesium powders used in military flares as well as in commercial applications;

•Improved sales of zirconium products including catalysis and traditional oxides; and

•Increased demand for Luxfer Graphic Arts' photo-engraving plates.

These increases were partially offset by a decrease in sales of flameless ration heaters and heater meals supplied by Luxfer Magtech.

Adjusted EBITDA

The 2.1 and 0.8 percentage point decrease in adjusted EBITDA for Elektron as a percentage of net sales in the second quarter and first half respectively of 2022 from 2021 was primarily the result of the continued cost pressure in the supply chain.

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.

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 June 26, 2022.

27

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 $6.8 million for the year-to-date in 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.

Cash provided by operating activities was $24.4 million in the first half of 2021. It was primarily related to net income from operating activities, net of the following non-cash items: depreciation and amortization; pension credit and net changes to assets and liabilities.

Investing activities

Net cash provided by investing activities was $0.8 million for the first half of 2022, compared to net cash used for investing activities of $2.3 million in 2021.The movement was primarily due the $3.7 million cash received in relation to the sale of our previously held-for-sale building in the Elektron division and the $0.7 million reduction in capital expenditures. In 2021, we also received net, $1.3 million from the divestiture of our U.S. aluminum gas cylinder facility in the U.S. and acquisition of SCI.

Financing activities

In the first half of 2022, net cash provided by financing activities was $6.0 million (2021: $13.6 million used for financing activities). We made net drawdown on our banking facilities of $18.1 million (2021: $4.4 million repayment) and dividend payments of $7.0 million (2021: $6.8 million), equating to $0.255 and $0.25 per ordinary share respectively. In addition, we paid out $1.4 million (2021: $1.5 million) in settling share based compensation and $3.7 million (2021: $0.9 million) in repurchasing our own shares as part of the share buyback program which equates to 138,000 shares (2021: 38,000 shares).

Capital Resources

Dividends

We paid year-to-date dividends in 2022 of $7.0 million (2021: $6.8 million year-to-date), or $0.255 per ordinary share.

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 IFRS as adopted by the E.U., 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.

28

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 2021 Annual Report on Form 10-K, filed with the SEC on February 24, 2022, we identified the critical accounting policies which affect our more significant estimates and assumptions used in preparing our consolidated financial statements.

29

Item 3.        Quantitative and qualitative disclosures about market risk

There have been no material changes in our market risk during the first half ended June 26, 2022. For additional information, refer to Item 7A of our 2020 Annual Report on Form 10-K, filed with the SEC on February 24, 2022.

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 June 26, 2022, 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 June 26, 2022, 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 June 26, 2022, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

30

PART II - OTHER INFORMATION

Item 1.        Legal Proceedings

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, 2021. 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 Second Quarter 2022, ended on June 26, 2022, and the Second Quarter 2021, ended on June 27, 2021.

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:

	Second Quarter				Year-to-date
In millions except share and per-share data	2022		2021		2022		2021
Basic earnings:
Net income from continuing operations	$	9.6	$	11.9	$	17.3	$	20.5
Net (loss) / income from discontinued operations	(0.3)		(0.9)		(0.4)		5.0
Net income	$	9.3	$	11.0	$	16.9	$	25.5
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,428,579		27,771,983		27,458,980		27,717,025
Dilutive effect of potential common stock	274,638		359,802		261,085		378,763
For diluted earnings per share	27,703,217		28,131,785		27,720,065		28,095,788
Earnings / (loss) per share using weighted average number of ordinary shares outstanding(1):
Basic earnings per ordinary share for continuing operations	$	0.35	$	0.43	$	0.63	$	0.74
Basic (loss) / earnings per ordinary share for discontinued operations	(0.01)		(0.03)		(0.01)		0.18
Basic earnings per ordinary share	$	0.34	$	0.40	$	0.62	$	0.92
Diluted earnings per ordinary share for continuing operations	$	0.35	$	0.42	$	0.62	$	0.73
Diluted (loss) / earnings per ordinary share for discontinued operations	(0.01)		(0.03)		(0.01)		0.18
Diluted earnings per ordinary share	$	0.34	$	0.39	$	0.61	$	0.91

(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 second quarter of 2022 and 2021 and year-to-date 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 2022.

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 2022 and 2021.

In 2021, our Superform U.K. business was also disclosed within assets and liabilities held-for-sale. The business was sold in September 2021.

Results of discontinued operations in the first half of 2022 and 2021 were as follows:

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 first half ended June 26, 2022, was 22.1%, compared to 7.7% for the 26-week period ended June 27, 2021. The 2021 rate was impacted by a $2.8 million deferred tax credit as a result of the enacted increase in the U.K. tax rate from 19% to 25% from April 2023.

In March 2022, 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 167,400 and the weighted average fair value of options granted in 2022 was estimated to be $17.82 per share.

Also in March 2022, approximately 17,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2019 to December 31, 2021. 50% of these awards vested immediately upon grant, with the remaining 50% vesting in March 2023.

In June 2022, we issued our annual share-based compensation grants under the Luxfer Holdings PLC Non-Executive Directors' Equity Incentive Plan. The total number of awards issued was 26,295 and the weighted-average fair value of options granted was estimated to be $15.50 per share.

The following table illustrates the assumptions used in deriving the fair value of share options granted during 2022 and the year-ended December 31, 2021:

	2022	2021
Dividend yield (%)	2.27	2.27
Expected volatility range (%)	42.80 - 59.03	42.80 - 59.03
Risk-free interest rate (%)	0.04 - 0.24	0.04 - 0.24
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.

Segmental Information

14.    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 EBITA(1) and 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.

1 Adjusted EBITA is adjusted EBITDA less depreciation

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.

Commitments and Contingencies

Committed and uncommitted banking facilities

The Company had committed banking facilities of $100.0 million at June 26, 2022, and December 31, 2021. Of these committed facilities, $26.8 million was drawn at June 26, 2022 and $10.8 million at December 31, 2021. The Company also had an additional $50.0 million of uncommitted facilities through an accordion provision.

The Company also has two separate (uncommitted) bonding facilities for bank guarantees, one denominated in GBP sterling of £0.5 million (2022: $0.6 million, 2021: $0.9 million), and one denominated in USD of $0.9 million (2021: $1.5 million). Of that dominated in GBP, £0.1 million ($0.1 million) and £0.1 million ($0.2 million) was utilized at June 26, 2022, and December 31, 2021, respectively. Of that denominated in USD, $0.9 million was utilized at June 26, 2022, and December 31, 2021, respectively.

The Company also has a $4.0 million separate overdraft facility of which none was drawn at June 26, 2022 and at December 31, 2021.

Contingencies

In November 2018, an explosion occurred at a third-party waste disposal and treatment site in Boise,

Idaho, reportedly causing property damage, personal injury, and one fatality. We had contracted with a service

company for removal and disposal of certain waste resulting from the magnesium powder manufacturing

operations at the Reade facility in Lakehurst, New Jersey. We believe this service company, in turn, apparently

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 do not believe that we are liable for the incident, have asserted such, and, therefore, do not currently expect this matter 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, 2021. 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 Second Quarter 2022, ended on June 26, 2022, and the Second Quarter 2021, ended on June 27, 2021.

[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 Second Quarter of 2022 and 2021 and year-to-date of 2022 has not been diluted, since the incremental shares included in the weighted-average number of shares outstanding would have been anti-dilutive.
