NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited consolidated condensed 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, 2020. 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 of a normal recurring nature, necessary for presentation 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, 2021, ended March 28, 2021, and the First Quarter, 2020, ended March 29, 2020.

Discontinued operations

Certain amounts in prior-year financial statements were reclassified to conform to the current-year presentation primarily due to the classification of certain businesses as discontinued operations.

Impact of COVID-19 on the Financial Statements

In March 2020, the World Health Organization characterized the coronavirus ("COVID-19") a pandemic. The rapid spread of the pandemic and the continuously evolving responses to combat it have had an increasingly negative impact on the global economy. Luxfer’s 2020 results were significantly affected by the global macro environment resulting from the COVID-19 pandemic, including broad-based market weakness, which was especially evident in our general industrial and transportation end-markets, contributing to a full year decline of 18.0% and 14.7% respectively, in each of those markets.

In the first quarter of 2021, with net sales down only 3.6% and adjusted EBITDA up 12% on the prior year quarter (which was largely unaffected by the pandemic), Luxfer continues to operate all of its facilities, following temporary closures at a small number of locations in the second and third quarters of 2020. Due to weaker demand resulting from uncertain economic conditions, potential supply constraints, and the impact of COVID-19, Luxfer also implemented additional cost saving programs in the second half of 2020, including headcount reductions. While Company performance is now much improved, as the situation continues to evolve, if warranted, the Company may again suspend or reduce operations at certain facilities. In view of the rapidly changing business environment, unprecedented market volatility and heightened degree of uncertainty resulting from COVID-19, we are currently unable to fully determine its future impact on our business. However, we continue to monitor the progression of the pandemic and its potential effect on our financial position, results of operations and cash flows.

The Company recognized that the COVID-19 pandemic constituted a triggering event in accordance with Accounting Standards Codification, ("ASC"), 350 Intangibles - Goodwill and Other, during the first quarter of 2020 and therefore performed an impairment assessment of its goodwill and other intangible assets. Based on the forecast at that time, we did not identify any impairments, nor marginal outcomes. During 2020 and in the first quarter of 2021, quarterly re-forecasts were performed to assess the impact COVID-19 was having on our results and liquidity, and in the fourth quarter of 2020 we carried out our annual goodwill and other intangibles impairment test using cash flows from the annual and strategic plan budgeting exercise. Nothing during the 2020 / 2021 re-forecasts nor the 2021 budget process has changed our assessment of fair value, with no impairments nor marginal outcomes identified. Assumptions and judgments are required in calculating the fair value of the reporting units. In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on our annual operating plan and

6

long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, changes in raw material prices and growth expectations for the industries and end markets we participate in. These assumptions and judgments may change as we learn more about the impact of the COVID-19 pandemic.

In relation to liquidity, the Company has access to a revolving credit facility (see Note 9) and has performed

stress testing on financial covenants using current forecast information and has not identified any liquidity concerns.

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 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 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	2021		2020
Basic earnings:
Net income from continuing operations	$	8.6	$	7.2
Net income / ( loss) from discontinued operations	5.9		(1.0)
Net income	$	14.5	$	6.2
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,658,871		27,440,423
Dilutive effect of potential common stock	398,452		453,635
For diluted earnings per share	28,057,323		27,894,058
Earnings / (loss) per share using weighted average number of ordinary shares outstanding:(1)
Basic earnings per ordinary share for continuing operations	$	0.31	$	0.26
Basic earnings / (loss) per ordinary share for discontinued operations	$	0.21	$	(0.04)
Basic earnings per ordinary share	$	0.52	$	0.23
Diluted earnings per ordinary share for continuing activities	$	0.31	$	0.26
Diluted earnings / (loss) per ordinary share for discontinued operations	$	0.21	$	(0.04)
Diluted earnings per ordinary share	$	0.52	$	0.22

(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 2020, 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. As a result, 453,635 shares combined were not included in the computation of diluted EPS for discontinued operations for the first quarter of 2020.

7

3.    Net sales

Disaggregated sales disclosures for the quarter ended March 28, 2021, and March 29, 2020, are included below and in Note 14, Segmental Information.

	First Quarter
	2021						2020
In millions	Gas Cylinders		Elektron		Total		Gas Cylinders		Elektron		Total
General industrial	$	5.8	$	21.7	$	27.5	$	6.2	$	27.7	$	33.9
Transportation	14.9		11.8		26.7		12.9		11.2		24.1
Defense, First Response & Healthcare	15.5		15.5		31.0		18.1		12.3		30.4
	$	36.2	$	49.0	$	85.2	$	37.2	$	51.2	$	88.4

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 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 $1.4 million restructuring charge in 2021 included $0.5 million of further costs associated with the closure of Luxfer Gas Cylinders France and $0.9 million in relation to rationalization activity in the Elektron segment, which included $0.1 million of asset and inventory impairments, largely in relation to the planned divestiture of our small Luxfer Magtech production facility in Ontario, Canada.

Restructuring-related costs included within Restructuring charges in the Condensed Consolidated Financial Statements by reportable segment were as follows:

	First Quarter
In millions	2021		2020
Severance and related costs
Gas Cylinders segment	$	0.5	$	2.6
Elektron segment	0.9		—
Other	—		0.2
Total restructuring charges	$	1.4	$	2.8

Activity related to restructuring, recorded in Other current liabilities in the consolidated balance sheets is summarized as follows:

In millions	2021
Balance at January 1,	$	9.0
Costs incurred	1.4
Cash payments and other	(1.1)
Balance at March 29,	$	9.3

5.    Acquisition-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.

We are currently undertaking the purchase price allocation in line with ASC 805 - Business combinations and as a result the allocations presented in the consolidated balance sheets are provisional based on our best current estimates. The provisional acquired assets and liabilities as of march 15, 2021 are presented as follows:

In millions	March 15, 2021
Accounts and other receivables	$	4.8
Inventories	6.7
Property, plant and equipment	9.5
Less:
Accounts payable	1.6
Accrued expenses	0.1
Net assets acquired	$	19.3
Purchase consideration	$	19.3

Actual and pro forma revenue and results of operations for the acquisition of SCI have not been presented as they are not material to the consolidated revenue and results of operations.

Acquisition-related costs of $0.2 million in the First Quarter of 2021 represent professional fees incurred in relation to the SCI acquisition.

Acquisition-related costs of $0.2 million in the First Quarter of 2020 related to M&A exploration activities net of a $0.1 million release of deferred contingent consideration.

6.    Other charges

Other charges of $1.1 million in the First Quarter of 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 a Human Resources administration matter. The Company expects the cash related to the settlement to be paid during the year, with no additional charge to the income statement.

7.    Supplementary balance sheet information (continued)

Held-for-sale assets and liabilities

In 2020, the Company classified its Superform aluminum superplastic forming business operating from sites in the U.S. and the U.K, and our U.S. aluminum gas cylinder business as assets and liabilities held-for-sale in accordance with ASC 205-20 Discontinued Operations. See Note 10 for a breakdown of this disposal group.

There was also one building valued at $3.7 million, within our Elektron Segment classified as held-for-sale assets, previously included within other current assets. The building was classified as held-for-sale in 2019, as the expectation was that the building would be sold in 2020. There are conditions attached to the sale which the Company now expects to be met in 2021 and as such the building continues to be classified as held-for-sale.

The respective assets and liabilities of the above disposal groups have been reclassified as held-for-sale per the table below.

Held-for-sale assets	March 28,		December 31,

10.    Discontinued Operations

Our Superform aluminum superplastic forming business operating from sites in the U.S. and the U.K, and our U.S. aluminum gas cylinder business were 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 these businesses as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented. Our U.S. aluminum business was sold in March 2021 and we expect the sales of our Superform businesses to occur in 2021.

The assets and liabilities of the Superform businesses have been presented within Current assets held-for-sale and Current liabilities held-for-sale in the consolidated balance sheets for 2021 and 2020 and our U.S. aluminum business in 2020. The Company has determined that the carrying value of the held-for-sale assets is recoverable and as a result no loss allowances have been recognized.

Results of discontinued operations were as follows:

	First Quarter
In millions	2021		2020
Net sales	$	9.7	$	15.4
Cost of goods sold	(10.1)		(15.0)
Gross profit	$	(0.4)	$	0.4
Selling, general and administrative expenses	(1.4)		(1.4)
Operating loss	$	(1.8)	$	(1.0)
Tax credit	0.2		—
Net loss	$	(1.6)	$	(1.0)

In the First Quarter of 2021, the Company made a $7.5 million gain on the sale of the U.S. aluminum business, net of a $2.0 million tax charge.

	First Quarter
In millions	2021
Cash consideration received	$	21.0

Net assets sold	(11.5)
Gross gain on disposition	9.5
Tax expense	(2.0)

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

Held-for-sale assets	March 28,		December 31,
In millions	2021		2020
Property, plant and equipment	$	1.4	$	7.9
Right-of-use-assets from operating leases	2.9		3.1

The depreciation and amortization, capital expenditures and significant non-cash items were as follows:

	First Quarter
In millions	2021		2020
Cash flows from discontinued operating activities:
Depreciation	$	0.2	$	0.3

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 for the Quarter ended March 28, 2021, was 21.1%, compared to 19.1% for the Quarter ended March 29, 2020.

12.    Share Plans

Total share-based compensation expense for the quarters ended March 28, 2021, and March 29, 2020, was as follows:

	First Quarter
In millions	2021		2020
Total share-based compensation charges	$	0.5	$	0.5

In March 2021, 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 110,000 and the weighted average fair value of options granted in 2021 was estimated to be $21.14 per share.

Also in March 2021, approximately 45,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2018 to December 31, 2020. The awards vested immediately upon grant.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2021 and the year-ended December 31, 2020:

	First Quarter	Year ended December 31,
	2021	2020
Dividend yield (%)	3.39 - 4.09	3.39 - 4.09
Expected volatility range (%)	36.48 - 56.28	36.48 - 56.28
Risk-free interest rate (%)	0.18 - 0.49	0.18 - 0.49
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
Models used	Black-Scholes	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.

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 Quarter ended March 28, 2021, and March 29, 2020, is included in the following summary:

	Net sales				Adjusted EBITDA

15.     Commitments and Contingencies

Committed and uncommited banking facilities

The Company had committed banking facilities of $150.0 million at March 28, 2021 and December 31, 2020. Of these committed facilities, $23.6 million was drawn at March 28, 2021 and $4.1 million at December 31, 2020.

The Company had a separate (uncommitted) facility for letters of credit which at March 28, 2021 was £1.0 million ($1.4 million) and December 31, 2020 was £1.0 million ($1.3 million). None of these were utilized at March 28, 2021 and December 31, 2020, respectively.

The Company also has two separate (uncommitted) bonding facilities for bank guarantees, one denominated in GBP sterling of £4.5 million (2021: $6.2 million, 2020: $6.1 million), and one denominated in USD of $1.5 million (2020: $1.5 million). Of that dominated in GBP, £1.0 million ($1.4 million) and £1.0 million ($1.4 million) was utilized at March 28, 2021, and December 31, 2020, respectively. Of that denominated in USD, $0.8 million was utilized at March 28, 2021 and $0.8 million was utilized at December 31, 2020.

The Company also has a $4.0 million separate overdraft facility of which none was drawn at March 28, 2021 and at December 31, 2020.

Contingencies

During February 2014, a cylinder was sold to a long-term customer and ruptured at one of their gas facilities. As a result of this rupture, three people were noted to have injuries such as loss of hearing. There was no major damage to assets of the customer. A claim has been launched by the three people who were injured in the incident. We have reviewed our quality control checks from around the time which the cylinder was produced and no instances of failures have been noted. It has also been noted by the investigator that the customer has poor quality and safety checks. As a result we do not believe that we are liable for the incident, and therefore, do not currently expect this case to have a material impact on the Company's financial position or results of operations.

In November 2018, an alleged 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 Manchester, 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. At present, we have received insufficient information on the cause

of the explosion. 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.

About Luxfer

Luxfer is a global manufacturer of highly-engineered industrial materials, which focuses on value creation by using its broad array of technical knowhow and proprietary technologies. Luxfer's high-performance products are used in defense and emergency response, healthcare, transportation, and general industrial settings. For more information, visit www.luxfer.com.

Key trends and uncertainties regarding our existing business

Impact of COVID-19 on operations

Luxfer’s top priority during this global pandemic is the health and well-being of our employees, customers, shareholders, and the communities in which we operate. The Company continues to monitor the COVID-19 situation closely, while simultaneously executing business continuity plans. These business continuity plans include, but are not limited to, (i) retooling operations to maintain social distance and maximize employee safety; (ii) increasing resources and efforts to satisfy demand from the most impactful parts of our business; (iii) expanding flexible work arrangements and policies, where practical, to maximize employee safety; (iv) increased monitoring of short-term cash flow, including measures to reduce costs and generate cash; and (v) providing regular updates to our shareholders, employees, customers, and suppliers in a transparent and timely manner.

As most product lines return to sequential growth, Luxfer continues to operate all of its facilities, following temporary closures at a small number of locations in the second quarter of 2020. Due to weaker demand resulting from uncertain economic conditions, potential supply constraints, and the impact of COVID-19, Luxfer implemented additional cost saving programs in the second half of 2020, including headcount reductions.

Luxfer’s 2020 results were significantly affected by the global macro environment resulting from the COVID-19 pandemic, including broad-based market weakness, which was especially evident in our general industrial and transportation end-markets. This was most pronounced in the second and third quarters, contributing to a full year decline of 18.0% and 14.7% respectively. However, in the first quarter of 2021 while general industrial has continued to show a decline versus prior year of 18.9% (largely due to the timing of oil and gas product orders), total revenue for continuing operations is down by only 3.6% versus the prior year quarter (which was largely unaffected by the onset of the pandemic). Transportation has experienced a recovery with growth of 10.8%, largely on the back of the continuing success of alternative fuel products; and Defense, First Response and Healthcare has grown by 2%. The Company continues to benefit from a strong balance sheet and demonstrates strong operating cash generation. Furthermore, with historically low net debt of $41.2 million and a 12% increase in quarter on quarter EBITDA, our net debt to EBITDA ratio has fallen to 0.7x at the end of Q1 2021 (from 1.0x at the end of 2020).

Operating objectives and trends

In 2021, we expect the following operating objectives and trends to impact our business:

•Continuing proactive response to the COVID-19 pandemic, including the health and well-being actions highlighted above, in addition to initiatives to stimulate demand for products, ensure continuity of supply and action, focused cost saving programs;

•Divestiture of non-strategic aluminum businesses (identified as discontinued operations) and integration of the recently acquired SCI, in the Gas Cylinders segment;

•Refocus on productivity acceleration and growth recovery post COVID-19 as we capitalize on lean manufacturing initiatives and pursue faster product innovation;

•Continued focus on developing global talent and implementing a high-performance culture; and

•Continued focus on improved operating cash generation with lower restructuring activity and maintaining strong working capital performance.

Net sales

The 3.6% decrease in consolidated net sales in 2021 from 2020 was primarily the result of:

•Decreased sales of Luxfer MEL Technologies Oil and Gas products due to timing of orders; and

•Lower sales of Luxfer Graphic Arts photoengraving products.

There was also continuing weakness affecting sales of SCBA cylinders used by first responders.

These decreases were partially offset by:

•Increased sales of flameless ration heaters and chemical detection kits in Luxfer Magtech;

•Continued growth in sales of alternative fuel (AF) cylinders; and

•Favorable foreign exchange variances of $3.0 million.

Gross profit

The 2.3 percentage point increase in gross profit as a percentage of sales in 2021 from 2020 was primarily the result of the impact of our ongoing cost reduction program as well as cost saving measures taken in response to COVID-19 in the second half of the prior year.

These favorable factors were partially offset by the impact of adverse product sales mix.

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

SG&A costs as a percentage of sales in 2021 from 2020 has decreased by 0.5 percentage points due to the impact of cost reduction programs.

Research and development costs

Research and development cost as a percentage of sales increased by 0.1 percentage points in 2021 relative to 2020.

Restructuring charges

The $1.4 million restructuring charge in 2021 included $0.5 million as a result of further costs associated with the previously announced closure of Luxfer Gas Cylinders France, which were largely legal and professional fees; and $0.9M of one-time employee termination benefits in the Elektron division, largely in relation to the planned divestiture of our small Luxfer Magtech production facility in Ontario, Canada.

The $2.8 million restructuring charge in 2020 was mainly ($2.6 million) the result of further costs associated with the announced closure of Luxfer Gas Cylinders France, including one-time employee benefits and associated legal and professional fees.

Acquisition-related costs

Acquisition related costs of $0.2 million in 2021 represents amounts incurred in relation to the acquisition of Structural Composites Industries.

Acquisition related costs of $0.2 million in 2020 represents amounts incurred in relation to merger and acquisition ("M&A"), exploration activities net of a $0.1 million release of deferred contingent consideration.

Other charges

Other charges in the First Quarter of 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.

22

Net interest expense

The 33.3% decrease in net interest expense in 2021 from 2020 was primarily due to the impact of the early repayment of $25.0 million of Loan Notes due 2021 in December of 2020.

Defined benefit pension credit

The $0.5 million decrease in defined benefit pension credit to $0.6 million in 2021 from $1.1 million in 2020 is primarily due to the combined effect on the U.K. plan of lower projected asset returns and a higher post-2030 inflation projection, partially offset by a fall in the discount rate.

Provision for income taxes

The movement in the statutory effective tax rate from 19.1% in 2020, to 21.1% in 2021, was primarily due to the favorable impact of tax rate changes partially offset by higher restructuring related non-deductibles both in the prior year. When stripping out the effect of the non-deductible restructuring expenses, our adjusted effective tax rate has increased to 20.4% in 2021 from 18.3% in 2020 largely as a result of the impact of the tax rate change in the prior year.

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; 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 discount on deferred consideration. 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:

	First Quarter						% / point change
In millions	2021			2020			2021 v 2020
Net sales	$	36.2		$	37.2		(2.7)	%
Adjusted EBITDA	6.0			4.2			42.9	%
% of net sales	16.6		%	11.3		%	5.3

Net sales

The 2.7% decrease in Gas Cylinders sales in 2021 from 2020 was primarily the result of:

•Lower sales of SCBA cylinders; and

•Lower sales of medical oxygen cylinders.

These decreases were partially offset by:

•Continued growth in sales of Alternative Fuels (AF) systems; and

•Increased sales of cylinders for gas calibration and other industrial applications.

Adjusted EBITDA

The 5.3 percentage point increase in adjusted EBITDA for Gas Cylinders as a percentage of net sales in 2021 from 2020 was primarily the result of the impact of cost reductions and favorable foreign exchange variances, partially offset by adverse product mix.

25

ELEKTRON

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

	First Quarter						% / point change
In millions	2021			2020			2021 v 2020
Net sales	$	49.0		$	51.2		(4.3)	%
Adjusted EBITDA	11.7			11.6			0.9	%
% of net sales	23.9		%	22.7		%	1.2

Net sales

The 4.3% decrease in Elektron sales in 2021 from 2020 was primarily the result of:

•Decreased sales of Oil and Gas products;

•Lower sales of Luxfer Graphic Arts photoengraving products; and

•Lower sales of chemical catalysis products.

These decreases were partially offset by:

•Growth in sales of flameless ration heaters and chemical detection kits in Luxfer Magtech; and

•Increased sales of magnesium aerospace alloys.

Adjusted EBITDA

The 1.2 percentage point increase in adjusted EBITDA for Elektron as a percentage of net sales in 2021 from 2020 was primarily the result of cost savings both as a result of the cost saving program and initiatives taken in response to COVID-19 in the second half of 2020, partially offset by adverse product sales mix.

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, 2021, 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 achieve organic sales growth; and

•hedging facilities used to manage our foreign exchange and aluminum purchase price 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.

26

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 March 28, 2021.

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 generated from operating activities was $15.2 million in the first quarter of 2021. It was primarily related to net income from operating activities, net of the following non-cash items: depreciation and amortization, pension contributions and net changes to assets and liabilities.

Cash used in operating activities was $4.5 million in the first quarter of 2020. It was primarily related to net income from operating activities, net of the following non-cash items: depreciation and amortization; asset impairment charges, pension contributions and net changes to assets and liabilities.

Investing activities

Net cash provided by investing activities was $0.3 million in the first quarter of 2021, compared to net cash used for investing activities of $2.5 million in the first quarter of 2020. The movement was primarily due to a decrease in capital expenditures which were $1.4 million and $2.5 million, in the first quarter of 2021, and 2020, respectively. We anticipate capital expenditures for fiscal 2021 to be approximately $10 million to $12 million. There was $21.0 million of proceeds received from our divestiture of our U.S. aluminum gas cylinder facility included within discontinued operations, partially offset by the $19.3 million consideration for the purchase of SCI.

Financing activities

In 2021, net cash provided from financing activities was $14.8 million (2020: $14.5 million inflow). We made net drawdowns on our banking facilities of $19.5 million (2020: $18.9 million drawdown) and dividend payments of $3.4 million (2020: $3.4 million), equating to $0.125 per ordinary share.

Dividends

We paid dividends in the first quarter of 2021 of $3.4 million (2019: $3.4 million), or $0.125 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.

Authorized shares

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

27

Contractual obligations

Off-balance sheet measures

At March 28, 2021, we had no off-balance sheet arrangements other than those disclosed in Note 15 to the consolidated financial statements.

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 2020 Annual Report on Form 10-K, filed with the SEC on March 2, 2021, we identified the critical accounting policies which affect our more significant estimates and assumptions used in preparing our consolidated financial statements.

In addition to those disclosed in our 2020 Annual Report on Form 10-K, we have an additional critical accounting policy for business combination, and more specifically the purchase price allocation, ("PPA").

Business combinations

Business combinations are accounted for using the purchase method. The cost of an acquisition is measured as

the aggregate of the consideration transferred, measured at acquisition date fair value, and the amount of any

non-controlling interest in the acquiree. The calculation of fair value is judgmental and takes into consideration quoted prices for identical assets and liabilities, prices of similar assets and liabilities sold in an active market and valuation techniques to estimate the fair value when there is no market or information on similar assets or liabilities available. Goodwill represents the excess of the cost of acquired businesses over the net of the fair value of identifiable tangible net assets and identifiable intangible assets purchased and liabilities assumed.

28

Item 3.        Quantitative and qualitative disclosures about market risk

There have been no material changes in our market risk during the quarter ended March 28, 2021. For additional information, refer to Item 7A of our 2020 Annual Report on Form 10-K, filed with the SEC on March 2, 2021.

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 March 28, 2021, 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 March 28, 2021, 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 and annual period ended March 28, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

29

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 15 (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 2020 Annual Report on Form 10-K.

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

Not applicable.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation and Responsibility for interim Financial Statements

Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited consolidated condensed 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, 2020. 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 of a normal recurring nature, necessary for presentation 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, 2021, ended March 28, 2021, and the First Quarter, 2020, ended March 29, 2020.

Discontinued operations

Certain amounts in prior-year financial statements were reclassified to conform to the current-year presentation primarily due to the classification of certain businesses as discontinued operations.

Impact of COVID-19 on the Financial Statements

In March 2020, the World Health Organization characterized the coronavirus ("COVID-19") a pandemic. The rapid spread of the pandemic and the continuously evolving responses to combat it have had an increasingly negative impact on the global economy. Luxfer’s 2020 results were significantly affected by the global macro environment resulting from the COVID-19 pandemic, including broad-based market weakness, which was especially evident in our general industrial and transportation end-markets, contributing to a full year decline of 18.0% and 14.7% respectively, in each of those markets.

In the first quarter of 2021, with net sales down only 3.6% and adjusted EBITDA up 12% on the prior year quarter (which was largely unaffected by the pandemic), Luxfer continues to operate all of its facilities, following temporary closures at a small number of locations in the second and third quarters of 2020. Due to weaker demand resulting from uncertain economic conditions, potential supply constraints, and the impact of COVID-19, Luxfer also implemented additional cost saving programs in the second half of 2020, including headcount reductions. While Company performance is now much improved, as the situation continues to evolve, if warranted, the Company may again suspend or reduce operations at certain facilities. In view of the rapidly changing business environment, unprecedented market volatility and heightened degree of uncertainty resulting from COVID-19, we are currently unable to fully determine its future impact on our business. However, we continue to monitor the progression of the pandemic and its potential effect on our financial position, results of operations and cash flows.

The Company recognized that the COVID-19 pandemic constituted a triggering event in accordance with Accounting Standards Codification, ("ASC"), 350 Intangibles - Goodwill and Other, during the first quarter of 2020 and therefore performed an impairment assessment of its goodwill and other intangible assets. Based on the forecast at that time, we did not identify any impairments, nor marginal outcomes. During 2020 and in the first quarter of 2021, quarterly re-forecasts were performed to assess the impact COVID-19 was having on our results and liquidity, and in the fourth quarter of 2020 we carried out our annual goodwill and other intangibles impairment test using cash flows from the annual and strategic plan budgeting exercise. Nothing during the 2020 / 2021 re-forecasts nor the 2021 budget process has changed our assessment of fair value, with no impairments nor marginal outcomes identified. Assumptions and judgments are required in calculating the fair value of the reporting units. In developing our discounted cash flow analysis, assumptions about future revenues and expenses, capital expenditures and changes in working capital are based on our annual operating plan and

long-term business plan for each of our reporting units. These plans take into consideration numerous factors including historical experience, anticipated future economic conditions, changes in raw material prices and growth expectations for the industries and end markets we participate in. These assumptions and judgments may change as we learn more about the impact of the COVID-19 pandemic.

In relation to liquidity, the Company has access to a revolving credit facility (see Note 9) and has performed

stress testing on financial covenants using current forecast information and has not identified any liquidity concerns.

Accounting standards issued but not yet effective

Earnings per share

Earnings Per Share [Abstract]

Earnings per share

Earnings per share

Basic earnings per share are computed by dividing net income 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 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	2021		2020
Basic earnings:
Net income from continuing operations	$	8.6	$	7.2
Net income / ( loss) from discontinued operations	5.9		(1.0)
Net income	$	14.5	$	6.2
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,658,871		27,440,423
Dilutive effect of potential common stock	398,452		453,635
For diluted earnings per share	28,057,323		27,894,058
Earnings / (loss) per share using weighted average number of ordinary shares outstanding:(1)
Basic earnings per ordinary share for continuing operations	$	0.31	$	0.26
Basic earnings / (loss) per ordinary share for discontinued operations	$	0.21	$	(0.04)
Basic earnings per ordinary share	$	0.52	$	0.23
Diluted earnings per ordinary share for continuing activities	$	0.31	$	0.26
Diluted earnings / (loss) per ordinary share for discontinued operations	$	0.21	$	(0.04)
Diluted earnings per ordinary share	$	0.52	$	0.22

(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 2020, 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. As a result, 453,635 shares combined were not included in the computation of diluted EPS for discontinued operations for the first quarter of 2020.

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 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.

Acquisition-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.

We are currently undertaking the purchase price allocation in line with ASC 805 - Business combinations and as a result the allocations presented in the consolidated balance sheets are provisional based on our best current estimates.

Held-for-sale assets and liabilities

In 2020, the Company classified its Superform aluminum superplastic forming business operating from sites in the U.S. and the U.K, and our U.S. aluminum gas cylinder business as assets and liabilities held-for-sale in accordance with ASC 205-20 Discontinued Operations. See Note 10 for a breakdown of this disposal group.

There was also one building valued at $3.7 million, within our Elektron Segment classified as held-for-sale assets, previously included within other current assets. The building was classified as held-for-sale in 2019, as the expectation was that the building would be sold in 2020. There are conditions attached to the sale which the Company now expects to be met in 2021 and as such the building continues to be classified as held-for-sale.

The respective assets and liabilities of the above disposal groups have been reclassified as held-for-sale per the table below.

Discontinued Operations

Discontinued Operations

Our Superform aluminum superplastic forming business operating from sites in the U.S. and the U.K, and our U.S. aluminum gas cylinder business were 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 these businesses as discontinued operations in the Condensed Consolidated Statements of Income for all periods presented. Our U.S. aluminum business was sold in March 2021 and we expect the sales of our Superform businesses to occur in 2021.

The assets and liabilities of the Superform businesses have been presented within Current assets held-for-sale and Current liabilities held-for-sale in the consolidated balance sheets for 2021 and 2020 and our U.S. aluminum business in 2020. The Company has determined that the carrying value of the held-for-sale assets is recoverable and as a result no loss allowances have been recognized.

Results of discontinued operations were as follows:

	First Quarter

Net sales	$	9.7	$	15.4
Cost of goods sold	(10.1)		(15.0)

Net loss	$	(1.6)	$	(1.0)

In the First Quarter of 2021, the Company made a $7.5 million gain on the sale of the U.S. aluminum business, net of a $2.0 million tax charge.

Income Tax Disclosure [Abstract]
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 for the Quarter ended March 28, 2021, was 21.1%, compared to 19.1% for the Quarter ended March 29, 2020.

Total share-based compensation expense for the quarters ended March 28, 2021, and March 29, 2020, was as follows:

	First Quarter
In millions	2021		2020
Total share-based compensation charges	$	0.5	$	0.5

In March 2021, 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 110,000 and the weighted average fair value of options granted in 2021 was estimated to be $21.14 per share.

Also in March 2021, approximately 45,000 awards were granted based on the achievement of total shareholder return targets from the period January 1, 2018 to December 31, 2020. The awards vested immediately upon grant.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2021 and the year-ended December 31, 2020:

	First Quarter	Year ended December 31,
	2021	2020
Dividend yield (%)	3.39 - 4.09	3.39 - 4.09
Expected volatility range (%)	36.48 - 56.28	36.48 - 56.28
Risk-free interest rate (%)	0.18 - 0.49	0.18 - 0.49
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
Models used	Black-Scholes	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 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.

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 Quarter ended March 28, 2021, and March 29, 2020, is included in the following summary:

	Net sales				Adjusted EBITDA

Commitments and Contingencies

Committed and uncommited banking facilities

The Company had committed banking facilities of $150.0 million at March 28, 2021 and December 31, 2020. Of these committed facilities, $23.6 million was drawn at March 28, 2021 and $4.1 million at December 31, 2020.

The Company had a separate (uncommitted) facility for letters of credit which at March 28, 2021 was £1.0 million ($1.4 million) and December 31, 2020 was £1.0 million ($1.3 million). None of these were utilized at March 28, 2021 and December 31, 2020, respectively.

The Company also has two separate (uncommitted) bonding facilities for bank guarantees, one denominated in GBP sterling of £4.5 million (2021: $6.2 million, 2020: $6.1 million), and one denominated in USD of $1.5 million (2020: $1.5 million). Of that dominated in GBP, £1.0 million ($1.4 million) and £1.0 million ($1.4 million) was utilized at March 28, 2021, and December 31, 2020, respectively. Of that denominated in USD, $0.8 million was utilized at March 28, 2021 and $0.8 million was utilized at December 31, 2020.

The Company also has a $4.0 million separate overdraft facility of which none was drawn at March 28, 2021 and at December 31, 2020.

Contingencies

During February 2014, a cylinder was sold to a long-term customer and ruptured at one of their gas facilities. As a result of this rupture, three people were noted to have injuries such as loss of hearing. There was no major damage to assets of the customer. A claim has been launched by the three people who were injured in the incident. We have reviewed our quality control checks from around the time which the cylinder was produced and no instances of failures have been noted. It has also been noted by the investigator that the customer has poor quality and safety checks. As a result we do not believe that we are liable for the incident, and therefore, do not currently expect this case to have a material impact on the Company's financial position or results of operations.

In November 2018, an alleged 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 Manchester, 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. At present, we have received insufficient information on the cause

of the explosion. 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

We prepared the accompanying unaudited consolidated condensed 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, 2020. 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 of a normal recurring nature, necessary for presentation 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, 2021, ended March 28, 2021, and the First Quarter, 2020, ended March 29, 2020.
