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 2021 and Second quarter and year-to-date of 2020 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 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 Second Quarter 2021, ended on June 27, 2021, and the Second Quarter 2020, ended on June 28, 2020.

Discontinued operations

Certain amounts in the 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 half of 2021, with net sales up 11.6%, a return to growth across all end-markets and adjusted EBITDA up 32.6% on the prior year, the Company has delivered two successive quarters of strong performance amid the global economic recovery from the COVID-19 pandemic. Furthermore, it continues to operate all of its facilities at near normal production levels, following temporary closures of a few 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 implemented additional cost saving programs in the second half of 2020, including headcount reductions. Company performance is now much improved and the apparent success of vaccine programs in the U.S. and Europe has given rise to fewer restrictions, increased stability and macroeconomic recovery. That said, the coronavirus is still prevalent in many of our markets, there are pressures on availability of raw materials and labor, continuing restrictions on international travel and there is therefore considerable uncertainty as to when fully normal conditions will prevail. If warranted, it is possible that the Company may again suspend or reduce operations at certain facilities, which could have an adverse 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 half 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.

7

Impact of COVID-19 on the Financial Statements (continued)

There have been no triggering events that has changed our assessment of fair value, as a result, 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. Furthermore, the Company has reported historically low levels of net debt and continual strong cash flow generation since the onset of the pandemic.

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 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	2021		2020		2021		2020
Basic earnings:
Net income from continuing operations	$	11.9	$	4.6	$	20.5	$	11.8
Net (loss) / income from discontinued operations	(0.9)		(0.5)		5.0		(1.5)
Net income	$	11.0	$	4.1	$	25.5	$	10.3
Weighted average number of €0.50 ordinary shares:
For basic earnings per share	27,771,983		27,540,377		27,717,025		27,490,955
Dilutive effect of potential common stock	359,802		428,448		378,763		442,164
For diluted earnings per share	28,131,785		27,968,825		28,095,788		27,933,119
Earnings / (loss) per share using weighted average number of ordinary shares outstanding3:
Basic earnings per ordinary share for continuing operations	$	0.43	$	0.17	$	0.74	$	0.43
Basic (loss) / earnings per ordinary share for discontinued operations	(0.03)		(0.02)		0.18		(0.05)
Basic earnings per ordinary share	$	0.40	$	0.15	$	0.92	$	0.37
Diluted earnings per ordinary share for continuing operations	$	0.42	$	0.16	$	0.73	$	0.42
Diluted (loss) / earnings per ordinary share for discontinued operations	(0.03)		(0.02)		0.18		(0.05)
Diluted earnings per ordinary share	$	0.39	$	0.15	$	0.91	$	0.37

3 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 2021 and 2020 and year-to-date 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.

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 $0.2 million and $1.6 million restructuring charges in the second quarter and first half of 2021, respectively, 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 primarily 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.

During the Second Quarter of 2020 we continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. The $0.8 million restructuring charge in the Second Quarter of 2020 was predominantly ($0.6 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. There was an additional $0.2 million of one-time employee benefits resulting from actions to reduce our fixed cost-base in light of the COVID-19 pandemic.

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

	Second Quarter				Year-to-date

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.

At the First Quarter of 2021 the purchase price allocation was ongoing and therefore a provisional allocation was presented. During the ongoing review of the purchase price allocation in the Second Quarter there has been a reallocation of $2.4 million from property, plant and equipment to goodwill. No other changes in the purchase price allocation presented at the First Quarter of 2021 have been identified, although the review remains ongoing.

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

Acquisition-related costs of $0.2 million in the first half 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 Half 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)

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. Our U.S. aluminum gas cylinder business was sold during the First Quarter of 2021.

There is 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.

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

Senior Facilities Agreement

During the Second Quarter of 2021, we repaid $23.9 million on the Revolving Credit Facility and the balance outstanding at June 27, 2021, was nil, and at December 31, 2020, was $4.1 million, with $100.0 million undrawn at June 27, 2021 and $145.9 million at December 31, 2020. During the quarter we have also reduced our Revolving credit facility to $100.0 million, from $150.0 million.

We are currently negotiating a new revolving credit facility which we expect to be in place by the third quarter 2021.

We have been in compliance with the covenants under the Senior Facilities Agreement throughout all of the quarterly measurement dates from and including September 30, 2011, to June 27, 2021.

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 gas cylinder business was sold in March 2021 for $20.6 million 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 gas cylinders 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.

In the First Quarter of 2021, the Company sold its U.S. aluminum gas cylinders business for $21.0 million which resulted in a gain on sale of $7.5 million, net of a $2.0 million tax charge which was recognized in the First Quarter of 2021.

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.

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

Held-for-sale assets	June 27,		December 31,
In millions	2021		2020
Property, plant and equipment	$	1.4	$	7.9

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 27, 2021, was 7.7%, compared to 19.0% for the 26-week period ended June 28, 2020. The 2021 rate has been 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 27, 2021, and June 28, 2020, was as follows:

	Second Quarter				Year-to-date
In millions	2021		2020		2021		2020
Total share-based compensation charges	$	0.9	$	0.8	$	1.4	$	1.3

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.

In June 2021, 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 19,184 and the weighted-average fair value of options granted was estimated to be $21.69 per share.

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

	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
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.

During the Second Quarter of 2021 the Directors approved a share buy-back program for the purchase of 200,000 ordinary shares over the course of 34 weeks, ceasing December 27, 2021. The program commenced on May 10, 2021 and during the Second Quarter the Company purchased 38,000 shares at a cost of $0.9 million and subsequently cancelled them.

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.

16

14.    Segmental Information (continued)

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 27, 2021, and June 28, 2020, 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 27, 2021 and $150.0 million at December 31, 2020. Of these committed facilities, nil was drawn at June 27, 2021 and $4.1 million at December 31, 2020. The current banking facilities expire July 31, 2022 and we are currently in negotiations for a new facility which we expect to be in place by the end of the Third Quarter 2021.

The Company had a separate (uncommitted) facility for letters of credit which at June 27, 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 June 27, 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: $6.3 million, 2020: $6.1 million), and one denominated in USD of $1.5 million (2020: $1.5 million). Of that dominated in GBP, £0.6 million ($0.8 million) and £1.0 million ($1.4 million) was utilized at June 27, 2021, and December 31, 2020, respectively. Of that denominated in USD, $0.8 million was utilized at June 27, 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 June 27, 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. 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 explosion occurred at a third-party waste disposal and treatment site in Boise,

Idaho, allegedly 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.

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; and (iv) providing regular updates to our shareholders, employees, customers, and suppliers in a transparent and timely manner.

Luxfer delivered strong second quarter results amid the continued global economic recovery from the COVID-19 pandemic, reporting a 29.2% increase in quarter on quarter revenues, as well as sequential revenue growth on a like-for-like basis excluding the impact of the SCI acquisition. This is in contrast to Luxfer’s 2020 results which were significantly affected by broad based market weakness with the impact most pronounced in the second and third quarters, which suffered a decline in revenues of around 18% versus the prior year. Company performance is now much improved and the apparent success of vaccine programs in the U.S. and Europe has given rise to fewer restrictions, increased stability and macroeconomic recovery. That said, the coronavirus is still prevalent in many of our markets, with continuing restrictions on international travel and pressures on the availability of raw materials and labor. There is therefore considerable uncertainty as to when fully normal conditions will prevail. If warranted, it is possible that the Company may again suspend or reduce operations at certain facilities, which could have an adverse effect on our financial position, results of operations and cash flows. The Company continues to benefit from a strong balance sheet and demonstrates strong operating cash generation. Furthermore, with historically low net debt of $39.5 million and a 63% increase in quarter on quarter EBITDA, our net debt to EBITDA ratio has fallen to 0.6x at the end of Q2 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 focus on cost saving programs;

•Divestiture of non-strategic aluminum businesses (identified as discontinued operations) 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 29.2% and 11.6% increase in consolidated net sales in the second quarter and first half, respectively, of 2021 from 2020 was primarily the result of a partial recovery in volumes adversely impacted by COVID-19 in the prior year, with the most significant factors being:

•Increased sales in the second quarter in Luxfer MEL Technologies, primarily of Oil and Gas magnesium alloys and zirconium catalysis automotive products, although Oil and Gas sales were marginally down in the first half overall due to a relatively strong performance in the first quarter 2020, before the pandemic took hold;

•Increased sales in Luxfer Magtech, primarily in the second quarter of magnesium powders for military applications;

•Increased sales in Luxfer Gas Cylinders in the second quarter, $8.0 million of which is due to the acquisition of Structural Composite Industries at the end of the first quarter, which positively impacted SCBA cylinders used by first responders, as well as cylinders used in aerospace and alternative fuels applications; and

•Favorable foreign exchange variances of $4.5 million in the quarter and $7.5 million in the first half.

Gross profit

The 2.7 and 2.2 percentage point increase in gross profit as a percentage of sales in the second quarter and first half, respectively of 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.

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

SG&A costs as a percentage of sales in 2021 from 2020 has decreased by 0.7 percentage points due to the impact of cost reduction programs.

Research and development costs

Research and development cost as a percentage of sales reduced by 0.4 and 0.1 percentage points in the second quarter and first half of 2021 relative to 2020 respectively, although the absolute value of expenditure was broadly flat.

Restructuring charges

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 Luxfer Magtech production facility in Ontario, Canada.

The $0.8 million and $3.6 million restructuring charge in the second quarter and first half of 2020 was predominantly ($0.6 million and $3.2 million respectively) 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 and disposal related costs

Net costs of $0.7 million and $0.9 million incurred in the second quarter and first half of 2021 respectively include 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.

24

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 $0.8 million in the second quarter of 2021 reduced from $1.1 million in the second quarter 2020, largely due to the $25 million early repayment in December 2020 of the Loan Notes 2021. This also resulted in lower net interest expense of $1.6 million in the first half of 2021 relative to $2.3 million in the first half 2020.

Defined benefit pension credit

The $0.5 million and $1.0 million decrease in defined benefit pension credit to $0.6 million and $1.2 million in the second quarter and first half of 2021 from $1.1 million and $2.2 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 in the U.K., partially offset by a fall in the discount rate.

Provision for income taxes

The movement in the statutory effective tax rate from 19.0% in 2020, to 7.7% in 2021, was primarily due to the impact of the enacted tax rate change in the U.K., 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. When stripping out the impact of this, as well as other less significant adjusting items, the adjusted effective tax rate has increased to 20.1% in 2021 from 18.4% in 2020, 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; 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 11 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	2021			2020			2021 v 2020		2021			2020			2021 v 2020

% of net sales	11.4		%	14.1		%	(2.7)		13.7		%	12.7		%	1.0

Net sales

The 24.0% and 10.7% increase in Gas Cylinders sales in the second quarter and first half, respectively, of 2021 from 2020 was primarily the result of:

•Increased sales of $8.0 million in the second quarter due to the acquisition of Structural Composite Industries at the end of the first quarter, which positively impacted SCBA cylinders used by first responders, as well as cylinders used in aerospace and alternative fuels applications; and

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

These increases were partially offset by a fall in sales of medical oxygen cylinders.

Adjusted EBITDA

The 2.7 percentage point decrease in adjusted EBITDA for Gas Cylinders as a percentage of net sales in the second quarter of 2021 relative to 2020 is largely due to adverse sales mix and losses incurred by the recently acquired SCI business. There was a 1.0 percentage point increase in profitability in the first half of 2021 from 2020.

ELEKTRON

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

	Second Quarter						% / point change		Year-to-date						% / point change

% of net sales	22.9		%	13.6		%	9.3		23.3		%	18.7		%	4.6

Net sales

The 34.3% and 12.4% increase in Elektron sales in the second quarter and first half, respectively, of 2021 from 2020 was primarily the result of a partial recovery from the COVID-19 related disruption in the prior year, including increased sales of:

•Zirconium-based automotive catalysts;

•Magnesium alloys used in Oil and Gas in the second quarter;

•Luxfer Magtech magnesium powders and MREs for military applications; and of

•Luxfer Graphic Arts photo-engraving plates.

Adjusted EBITDA

The 9.3 and 4.6 percentage point increase in adjusted EBITDA for Elektron as a percentage of net sales in the second quarter and first half respectively of 2021 from 2020 was primarily the result of the partial recovery in volumes impacted by the pandemic in the prior year, characterized by improved product sales mix and continuing benefit from cost saving measures.

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 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.

Our Revolving Credit Facility expires on July 31, 2022 and we are currently negotiating a new facility which we expect to be in place by the third quarter 2021.

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.

28

We have been in compliance with the covenants under the Note Purchase and Private Shelf Agreement and the Senior Facilities Agreement throughout all of the quarterly measurement dates from inception to June 27, 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 provided by operating activities was $24.4 million for the year-to-date in 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 provided by operating activities was $9.5 million in the first half 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 used for investing activities was $2.3 million for the first half of 2021, compared to net cash used for investing activities of $4.4 million in 2020.The movement was primarily due acquisition and disposal activity. There was $20.6 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 acquisition of SCI. In addition, capital expenditures decreased from $4.4 million in the first of 2020, to $3.6 million in 2021.

Financing activities

In the first half of 2021, net cash used for financing activities was $13.6 million (2020: $6.9 million). We made net repayments on our banking facilities of $4.4 million (2020: $0.4 million drawdown) and dividend payments of $6.8 million (2020: $6.8 million), equating to $0.25 per ordinary share. In 2020 we received $1.1 million in relation to proceeds from sales of shares, no shares have been sold in 2021. In addition, we paid out $1.5 million (2020: $1.2 million) in settling share based compensation. During the quarter we commenced a share buy-back program which resulted in an outflow of $0.9 million.

During the Second Quarter of 2021 the Directors approved a share buy-back program for the purchase of 200,000 ordinary shares over the course of 34 weeks, ceasing December 27, 2021. The program commenced on May 10, 2021 and during the Second Quarter the Company purchased 38,000 shares, resulting in a cash outflow of $0.9 million (2020: $nil).

Capital Resources

Dividends

We paid year-to-date dividends in 2021 of $6.8 million (2020: $6.8 million year-to-date), or $0.25 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.

29

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:

	Payments Due by Period
	Total		Less than 1 year		1 – 3 years		3 – 5 years		After 5 years

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.

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 27, 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 June 27, 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 June 27, 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 year-to-date period ended June 27, 2021, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

31

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

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 Second Quarter 2021, ended on June 27, 2021, and the Second Quarter 2020, ended on June 28, 2020.

Discontinued operations

Certain amounts in the 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 half of 2021, with net sales up 11.6%, a return to growth across all end-markets and adjusted EBITDA up 32.6% on the prior year, the Company has delivered two successive quarters of strong performance amid the global economic recovery from the COVID-19 pandemic. Furthermore, it continues to operate all of its facilities at near normal production levels, following temporary closures of a few 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 implemented additional cost saving programs in the second half of 2020, including headcount reductions. Company performance is now much improved and the apparent success of vaccine programs in the U.S. and Europe has given rise to fewer restrictions, increased stability and macroeconomic recovery. That said, the coronavirus is still prevalent in many of our markets, there are pressures on availability of raw materials and labor, continuing restrictions on international travel and there is therefore considerable uncertainty as to when fully normal conditions will prevail. If warranted, it is possible that the Company may again suspend or reduce operations at certain facilities, which could have an adverse 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 half 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.

Impact of COVID-19 on the Financial Statements (continued)

There have been no triggering events that has changed our assessment of fair value, as a result, 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. Furthermore, the Company has reported historically low levels of net debt and continual strong cash flow generation since the onset of the pandemic.

Accounting standards issued but not yet effective

None that will be material to the Company.

Earnings per share

Earnings Per Share [Abstract]

Earnings per share

Earnings per share

Basic earnings per share are computed by dividing net income or loss for the period by the weighted-average number of ordinary shares outstanding, net of treasury shares and shares held in ESOP. Diluted earnings per share are computed by dividing net income 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	2021		2020		2021		2020
Basic earnings:
Net income from continuing operations	$	11.9	$	4.6	$	20.5	$	11.8
Net (loss) / income from discontinued operations	(0.9)		(0.5)		5.0		(1.5)
Net income	$	11.0	$	4.1	$	25.5	$	10.3
Weighted average number of €0.50 ordinary shares:
For basic earnings per share	27,771,983		27,540,377		27,717,025		27,490,955
Dilutive effect of potential common stock	359,802		428,448		378,763		442,164
For diluted earnings per share	28,131,785		27,968,825		28,095,788		27,933,119
Earnings / (loss) per share using weighted average number of ordinary shares outstanding3:
Basic earnings per ordinary share for continuing operations	$	0.43	$	0.17	$	0.74	$	0.43
Basic (loss) / earnings per ordinary share for discontinued operations	(0.03)		(0.02)		0.18		(0.05)
Basic earnings per ordinary share	$	0.40	$	0.15	$	0.92	$	0.37
Diluted earnings per ordinary share for continuing operations	$	0.42	$	0.16	$	0.73	$	0.42
Diluted (loss) / earnings per ordinary share for discontinued operations	(0.03)		(0.02)		0.18		(0.05)
Diluted earnings per ordinary share	$	0.39	$	0.15	$	0.91	$	0.37

3 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 2021 and 2020 and year-to-date 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.

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.

Restructuring

The $0.2 million and $1.6 million restructuring charges in the second quarter and first half of 2021, respectively, 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 primarily 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.

During the Second Quarter of 2020 we continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. The $0.8 million restructuring charge in the Second Quarter of 2020 was predominantly ($0.6 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. There was an additional $0.2 million of one-time employee benefits resulting from actions to reduce our fixed cost-base in light of the COVID-19 pandemic.

Acquisition and disposal related costs

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.

At the First Quarter of 2021 the purchase price allocation was ongoing and therefore a provisional allocation was presented. During the ongoing review of the purchase price allocation in the Second Quarter there has been a reallocation of $2.4 million from property, plant and equipment to goodwill. No other changes in the purchase price allocation presented at the First Quarter of 2021 have been identified, although the review remains ongoing.

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

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

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. Our U.S. aluminum gas cylinder business was sold during the First Quarter of 2021.

There is 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 and Disposal Groups [Abstract]

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 gas cylinder business was sold in March 2021 for $20.6 million 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 gas cylinders 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:

	Second Quarter				Year-to-date
In millions	2021		2020		2021		2020
Net sales	$	4.9	$	12.9	$	14.6	$	28.3

Tax credit	0.5		—		0.7		—
Net loss	$	(0.5)	$	(0.5)	$	(2.1)	$	(1.5)

In the First Quarter of 2021, the Company sold its U.S. aluminum gas cylinders business for $21.0 million which resulted in a gain on sale of $7.5 million, net of a $2.0 million tax charge which was recognized in the First Quarter of 2021.

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.

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

Held-for-sale assets	June 27,		December 31,
In millions	2021		2020
Property, plant and equipment	$	1.4	$	7.9

Income Taxes

Income Taxes

We manage our affairs so that we are centrally managed and controlled in the United Kingdom (“U.K.”) and therefore have our tax residency in the U.K. The provision for income taxes consists of provisions for the U.K. and international income taxes. We operate in an international environment with operations in various locations outside the U.K. Accordingly, the consolidated income tax rate is a composite rate reflecting the earnings in the various locations and the applicable rates.

The effective income tax rate on continuing operations for the first half ended June 27, 2021, was 7.7%, compared to 19.0% for the 26-week period ended June 28, 2020. The 2021 rate has been 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.

Total share-based compensation expense for the quarters ended June 27, 2021, and June 28, 2020, was as follows:

In millions	2021		2020		2021		2020
Total share-based compensation charges	$	0.9	$	0.8	$	1.4	$	1.3

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.

In June 2021, 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 19,184 and the weighted-average fair value of options granted was estimated to be $21.69 per share.

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

	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
Model used	Black-Scholes & Monte-Carlo	Black-Scholes & Monte-Carlo

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

Segment Reporting [Abstract]

Segmental Information

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.

14.    Segmental Information (continued)

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 27, 2021, and June 28, 2020, is included in the following summary:

Commitments and Contingencies

Committed and uncommitted banking facilities

The Company had committed banking facilities of $100.0 million at June 27, 2021 and $150.0 million at December 31, 2020. Of these committed facilities, nil was drawn at June 27, 2021 and $4.1 million at December 31, 2020. The current banking facilities expire July 31, 2022 and we are currently in negotiations for a new facility which we expect to be in place by the end of the Third Quarter 2021.

The Company had a separate (uncommitted) facility for letters of credit which at June 27, 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 June 27, 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: $6.3 million, 2020: $6.1 million), and one denominated in USD of $1.5 million (2020: $1.5 million). Of that dominated in GBP, £0.6 million ($0.8 million) and £1.0 million ($1.4 million) was utilized at June 27, 2021, and December 31, 2020, respectively. Of that denominated in USD, $0.8 million was utilized at June 27, 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 June 27, 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. 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 explosion occurred at a third-party waste disposal and treatment site in Boise,

Idaho, allegedly 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

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.

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 2021, ended on June 27, 2021, and the Second Quarter 2020, ended on June 28, 2020.

Discontinued operations

Discontinued operations

Certain amounts in the 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

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 half of 2021, with net sales up 11.6%, a return to growth across all end-markets and adjusted EBITDA up 32.6% on the prior year, the Company has delivered two successive quarters of strong performance amid the global economic recovery from the COVID-19 pandemic. Furthermore, it continues to operate all of its facilities at near normal production levels, following temporary closures of a few 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 implemented additional cost saving programs in the second half of 2020, including headcount reductions. Company performance is now much improved and the apparent success of vaccine programs in the U.S. and Europe has given rise to fewer restrictions, increased stability and macroeconomic recovery. That said, the coronavirus is still prevalent in many of our markets, there are pressures on availability of raw materials and labor, continuing restrictions on international travel and there is therefore considerable uncertainty as to when fully normal conditions will prevail. If warranted, it is possible that the Company may again suspend or reduce operations at certain facilities, which could have an adverse 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 half 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.

Impact of COVID-19 on the Financial Statements (continued)

There have been no triggering events that has changed our assessment of fair value, as a result, 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. Furthermore, the Company has reported historically low levels of net debt and continual strong cash flow generation since the onset of the pandemic.

[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 2021 and Second quarter and year-to-date of 2020 has not been diluted, since the incremental shares included in the weighted-average number of shares outstanding would have been anti-dilutive.
