NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.    Basis of Presentation and Responsibility for interim Financial Statements

We prepared the accompanying unaudited consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements, except for the adoption for Accounting Standards Codification ("ASC") Topic 842, "Leases". 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, 2018. 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, 2019, ended March 31, 2019, and the First Quarter, 2018, ended April 1, 2018.

Adoption of new accounting standards

On January 1, 2019, we adopted ASC Topic 842, "Leases", and applied the modified retrospective approach to recognizing any right-of-use assets and lease liabilities. Upon adoption, we have recognized all of our leases greater than one-year in duration and greater than $5,000 fair value, on the balance sheet as right-of-use assets and lease liabilities. This has resulted in us restating the prior period comparatives and have recognized a right-of-use asset of $21.2 million at January 1, 2018, with a corresponding lease liability, split $3.1 million, recognized in Other current liabilities, and $18.1 million recognized in Other non-current liabilities. Classification as either operating or finance is based on criteria largely similar to those applied in ASC 840 but without explicit bright lines. We have made certain assumptions in judgments when applying ASC 842, those judgments of most significance are as follows:

• We elected the package of practical expedients available for transition which allow us to not reassess:

◦ Whether expired or existing contracts contain leases under the new definition of a lease;

◦ Lease classification for expired or existing leases; and

◦ Whether previously capitalized initial direct costs would qualify for capitalization under ASC 842.

• We did not elect to use hindsight for transition when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset.

• We did not elect to reassess whether land easements meet the definition of a lease if they were not accounted for as leases under the former rules.

• For all asset classes, we elected to not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less.

• For all asset classes, we elected to not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component.

6

1.    Basis of Presentation and Responsibility for interim Financial Statements (continued)

We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheet as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Some of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use.

In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various tenors (ranging from one-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments.

The standard had no impact on our results of operations or cash flows. In addition, new disclosures are provided to enable users to assess the amount, timing and uncertainty of cash flows arising from leases.

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	2019			2018
Basic earnings:
Net (loss) / income	$	(3.8	)	$	9.9
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,032,677			26,512,765
Dilutive effect of potential common stock	—			385,118
For diluted earnings per share	27,032,677			26,897,883
(Loss) / earnings per share using weighted average number of ordinary shares outstanding:
Basic (loss) / earnings per ordinary share	$	(0.14	)	$	0.37
Diluted (loss) / earnings per ordinary share	$	(0.14	)	$	0.37

In the first quarter of 2019, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss. As a result, 735,730 combined were not included in the computation of diluted EPS.

3.    Revenue

Disaggregated sales disclosures for the quarter ended March 31, 2019, and April 1, 2018, are included below and in Note 14, Segmental Information.

	First Quarter
	2019						2018
In millions	Gas Cylinders		Elektron		Total		Gas Cylinders		Elektron		Total
General industrial	$	13.1	$	30.6	$	43.7	$	13.0	$	28.4	$	41.4

	$	58.4	$	62.0	$	120.4	$	59.3	$	60.4	$	119.7

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. Design and tooling arrangements are the only contracts for which sales are recognized over time. Sales from these sources combined accounted for less than 3% of the Company’s sales for the quarters ended March 31, 2019, and April 1, 2018. All consideration from contracts with customers is included in these amounts.

The following table provides information about contract receivables, contract assets and contract liabilities from contracts with customers:

In millions	March 31, 2019			December 31, 2018
Contract receivables	$	1.9		$	1.5
Contract assets	2.0			2.1
Contract liabilities	(0.8		)	(1.1		)

Contract assets consist of $2.0 million accrued unbilled amounts relating to tooling revenue and are recognized in prepayments and accrued income in the consolidated balance sheets. Of the $2.1 million contract assets recognized as of December 31, 2018, $1.1 million was billed to customers and transferred to receivables as of March 31, 2019.

Contract liabilities of $0.8 million consist of advance payments and billing above costs incurred and are recognized as other current liabilities. Significant changes in contract liabilities balances during the period are as follows:

In millions	2019
As at January 1,	$	(1.1	)
Payments received / amounts billed	(0.1		)
Costs incurred / revenue recognized	0.4
As at March 31,	$	(0.8	)

4.    Restructuring

During the First Quarter of 2019 and the year ended December 31, 2018, we initiated and continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. Initiatives during the First Quarter of 2019 were predominantly in relation to the continued consultation to close the Gas Cylinders segment's French site. There is an expectation that further costs will be incurred during 2019.

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

	First Quarter
In millions	2019		2018
Severance and related costs
Gas Cylinders segment	$	8.9	$	0.2
Elektron segment	0.1		0.5
Total restructuring charges	$	9.0	$	0.7

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

In millions	2019
Balance at January 1,	$	5.2
Costs incurred	9.0
Cash payments and other	(2.3		)
Balance at March 31,	$	11.9

5.    Acquisition related costs

Acquisition-related costs of $4.6 million in the First Quarter, 2019, (2018: nil) relate to a $3.5 million termination payment and our professional and legal fees incurred in connection with the aborted acquisition of Neo Performance Materials.

9.    Derivatives and Financial Instruments

The Company's financial instruments comprise bank and other loans, senior loan notes, derivatives, trade payables deferred and deferred contingent consideration. Other than derivatives, the main purpose of these financial instruments is to raise finance for the Company's operations. The Company also has various financial assets such as trade receivables and cash and cash equivalents, which arise directly from its operations.

Derivative financial instruments                                        We are exposed to market risk during the normal course of business from changes in currency exchange rates, interest rates and commodity prices such as aluminum prices. We manage exposures through a combination of normal operating and financing activities and through the use of derivative financial instruments such as foreign currency forward purchase contracts and aluminum forward purchase contracts. We do not use market risk-sensitive instruments for trading or speculative purposes. The Company had $0.3 million and $0.1 million derivative financial instruments disclosed within Accounts and other receivables as of March 31, 2019 and December 31, 2018, respectively. There were also $0.2 million and nil derivative financial instruments recorded in Other current liabilities at March 31, 2019, and December 31, 2018, respectively.

The fair value of forward foreign currency exchange contracts deferred in equity was a loss of $0.6 million and a loss of $0.4 million at March 31, 2019, and December 31, 2018, respectively. During the First Quarter of 2019, $0.2 million was transferred to the Income Statement.

Forward foreign currency exchange contracts                                    The Company incurs currency transaction risk whenever one of the Company's operating subsidiaries enters into either a purchase or sales transaction in a currency other than its functional currency. Currency transaction risk is reduced by matching sales and expenses in the same currency. The Company's U.S. operations have little currency exposure, as most purchases, costs and sales are conducted in U.S. dollars. The Company's U.K. operations are exposed to exchange transaction risks, mainly because these operations sell goods priced in euros and U.S. dollars, and purchase raw materials priced in U.S. dollars and its functional currency is GBP sterling. The Company also incurs currency transaction risk if it lends currency other than its functional currency to one of its joint venture partners.

At March 31, 2019, and December 31, 2018, the Company held various forward foreign currency exchange contracts designated as hedges in respect of forward sales for U.S. dollars, euros and Australian dollars for the receipt of GBP sterling or euros. The Company also held forward foreign currency exchange contracts designated as hedges in respect of forward purchases for U.S. dollars by the sale of GBP sterling. The contract totals in GBP sterling and euros, range of maturity dates and range of exchange rates are disclosed below, with the value denominated in GBP sterling given that is the currency the majority of the contracts are held in.

9.    Derivatives and Financial Instruments (continued)

Fair value of financial instruments                                        

The following methods were used to estimate the fair values of each class of financial instrument:

Cash at bank and in hand / overdrafts                                        The carrying value approximates to the fair value as a result of the short-term maturity of the instruments. Cash at bank and in hand are subject to a right to offset in the U.S.

Bank loans                                                    Bank and other loans, excluding overdrafts, of $86.3 million were outstanding at March 31, 2019, and $75.0 million were outstanding at December 31, 2018. Bank and other loans are shown net of issue costs of $1.3 million and $1.4 million at March 31, 2019, and December 31, 2018, respectively, and are to be amortized to the expected maturity of the facilities. Of the bank and other loans outstanding, $11.3 million and none is variable interest rate debt and subject to floating interest rate risk, with the remainder being fixed rate debt, at March 31, 2019, and December 31, 2018, respectively.

Forward foreign currency exchange rate contracts                                The fair value of these contracts was calculated by determining what the Company would be expected to receive or pay on termination of each individual contract by comparison to present market prices.

LME derivative contracts                                            The fair value of these contracts has been calculated by valuing the contracts against the equivalent forward rates quoted on the LME.

Deferred contingent consideration

The deferred contingent consideration is in relation to the acquisition of Truetech and Innotech (Luxfer Magtech) in 2014 and is linked to the future profitability of the entity.

The Company uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities.

Level 2: other techniques for which all inputs which have a significant effect on the recorded fair value are observable, either directly or indirectly.

Level 3: techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

The fair values of the financial instruments of the Company at March 31, 2019, were analyzed using the hierarchy as follows:

In millions	Total			Level 1		Level 2			Level 3
Derivative financial assets:
Foreign currency contract assets	$	0.3		$	—	$	0.3		$	—
Derivative financial liabilities:
Foreign currency contract liabilities	(0.2		)	—		(0.2		)	—

Change in unrealized (gains) or losses for the period included in profit and loss for assets held at the end at March 31,	$	—

10.    Income Taxes

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

The effective income tax rate for the First Quarter ended March 31, 2019, was negative 131%, compared to 23.6% for the First Quarter ended April 1, 2018. The 2019 rate was adversely affected by the impact of non-deductible expenses related to the aborted acquisition of Neo Performance Materials and restructuring activities. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the U.S. Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. For 2018, the Company considered in its estimated annual effective tax rate additional provisions of the Act including changes to the deduction for executive compensation and interest expense, a tax on global intangible low-taxed income provisions (“GILTI”), the base erosion anti-abuse tax, and a deduction for foreign-derived intangible income. The Company has elected to treat tax on GILTI income as a period cost and has therefore included it in its annual estimated effective tax rate.

11.     Pension Plans

The principal defined benefit pension plan in the U.K. is the Luxfer Group Pension Plan. The Company’s other arrangements are less significant than the Luxfer Group Pension Plan, the largest being the BA Holdings, Inc. Pension Plan in the U.S.

Components of net periodic benefit cost for our pension plans for the First Quarter ended March 31, 2019, and 2018 were as follows:

	First Quarter
In millions	2019			2018
Net periodic benefit credit
Interest cost	$	2.7		$	2.7
Expected return on plan assets	(3.8		)	(4.4		)
Amortization of:
Net actuarial loss	0.7			0.6
Prior service credit	(0.1		)	(0.1		)
Net periodic benefit credit	$	(0.5	)	$	(1.2	)
In respect of defined contribution plans
Total charge for defined contribution plans	1.2			1.5
Total charge for pension plans	$	0.7		$	0.3

15

11.     Pension Plans (continued)

In accordance with ASC 715, defined benefit credit is split in the income statement, with $0.1 million (2018: $0.2 million) of expenses recognized within Selling, general and administrative expenses and a credit of $0.6 million (2018: $1.4 million) recognized below Operating (loss) / income in the income statement.

12.    Share Plans

Total share-based compensation expense for the quarters ended March 31,2019, and April 1, 2018, was as follows:

	First Quarter
In millions	2019		2018
Total share-based compensation charges	$	2.6	$	0.5

In March 2019, 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 200,000 and the weighted-average fair value of options granted in 2019 was estimated to be $17.70 per share.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2019 and the year-ended December 31, 2018,:

	2019	2018
Dividend yield (%)	4.00	4.00
Expected volatility range (%)	22.65 - 35.77	22.65 - 35.77
Risk-free interest rate (%)	0.12 - 2.57	0.12 - 2.57
Expected life of share options range (years)	1.00 - 4.00	0.50 - 6.00
Weighted average exercise price ($)	$0.89	$0.65
Model used	Black-Scholes & Monte-Carlo	Black-Scholes & Monte-Carlo

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

14.    Segmental Information

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

Gas Cylinders segment

Our Gas Cylinders segment manufactures and markets specialized products using aluminum, titanium and carbon composites, 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. The segment also forms lightweight aluminum and titanium panels into highly complex shapes that are used mainly in the transportation industry.

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 expense; qualifying restructuring charges; impairment charges; legal expenses incurred from patent litigation with a competitor; profit on sale of redundant site; acquisition-related charges / credits; loss on disposal of property, plant and equipment; depreciation and amortization; and unwind of 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 First Quarter ended March 31, 2019, and April 1, 2018, is included in the following summary:

	Net sales				Adjusted EBITDA
In millions	2019		2018		2019		2018

16.     Commitments and Contingencies

Committed banking facilities

At March 31, 2019, and December 31, 2018, the Company had committed banking facilities of $150.0 million. The facilities were for providing loans and overdrafts, with a separate facility for letters of credit which at March 31, 2019, was £7.0 million ($9.1 million) and December 31, 2018, was £7.0 million ($8.9 million). Of the committed facilities, $7.6 million was drawn for overdrafts, no loans were drawn and no letters of credit were utilized at March 31, 2019, $3.5 million, nil and nil at December 31, 2018. The Company also has a separate bonding facility for bank guarantees denominated in GBP sterling of £3.0 million (2019: $3.9 million, 2018: $3.8 million), of which $1.0 million ($1.4 million) was utilized at March 31, 2019, and December 31, 2018, respectively.

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 minor injuries such as loss of hearing. There was no major damage to assets of the customer. A claim was launched by the three people who were injured in the incident and a prosecutor has been appointed. We had reviewed our quality control checks from around the time which the cylinder was produced and no instances of failures were 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.

Item 2.        Management's Discussion and Analysis of Financial Condition and Results of Operations

Information regarding forward-looking statements

This Interim Report on Form 10-Q contains certain statements, statistics and projections that are, or may be, forward-looking. These forward-looking statements are subject to known and unknown risks, uncertainties, assumptions and other factors that could cause our actual results of operations, financial condition, liquidity, performance, prospects, opportunities, achievements or industry results, as well as those of the markets we serve or intend to serve, to differ materially from those expressed in, or suggested by, these forward-looking statements. The accuracy and completeness of all such statements, including, without limitation, statements regarding our future financial position, strategy, plans and objectives for the management of future operations, is not warranted or guaranteed. These statements typically contain words such as "believes," "intends," "expects," "anticipates," "estimates," "may," "will," "should" and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. We undertake no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

Key trends and uncertainties regarding our existing business

The following trends and uncertainties affected our financial performance in the First Quarter, 2019, and will likely impact our results in the future:

• We continued along our transformation journey and initiated certain business restructuring initiatives aimed at reducing our fixed cost structure. We expect that these actions will contribute to further margin growth in 2019.

• We saw growth and profit margin expansion in both the Elektron and Gas Cylinders Segments.

• We have experienced material and other cost inflation. We strive for productivity improvements, and we implement increases in selling prices to mitigate this inflation.

In 2019, our operating objectives and trends we expect to impact our business include the following:

• We have converted from foreign private issuer status to domestic issuer status, which requires us to comply with the U.S. SEC domestic reporting regime from January 1, 2019.

• Improvement of the Gas Cylinder Segment with a project to consolidate the French operation into the U.K. and U.S to reduce fixed costs and safeguard competitiveness.

• Focusing on developing global talent and implementing a high-performance culture.

• Productivity acceleration and growth recovery as we move towards a lean manufacturing process and focused and faster product innovation.

23

Net sales

The 0.6% increase in consolidated net sales in 2019 from 2018 was primarily the result of:

• Increased sales of zirconium-based industrial and automotive catalysis materials;

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

These increases were partially offset by:

• $4.4 million negative impact from FX;

• Lower sales following significant hurricane-related disaster relief sales in the prior year;

• Lower sales of SCBA cylinders; and

• Lower sales of graphic arts products due to productivity challenges following plant consolidation.

Gross profit

The 0.3 percentage point decrease in gross profit as a percentage of sales in 2019 from 2018 was primarily the result of:

• Adverse mix impact of lower Luxfer Magtech disaster relief product sales in the current quarter; and

• Productivity challenges at Luxfer Gas Cylinders France, following the announcement in Q4 2018 that we were in consultation to close the facility.

These adverse factors were partially offset by improvements due to:

• Favorable mix impact of higher sales of zirconium catalysis materials; and

• Continued production-based cost savings.

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

The 0.9 percentage point increase in SG&A costs as a percentage of sales in 2019 from 2018 was primarily the result of higher share-based compensation charges and higher integration costs associated with the Graphic Arts plant consolidation exercise, following the closure of the Findlay, OH site in Q4 2018.

Research and development costs

Research and development cost as a percentage of sales was relatively flat with a 0.1 percentage point decrease in 2019 relative to 2018.

Restructuring charges

The $9.0 million restructuring charge in 2019 was predominantly, ($8.9 million), the result of further costs associated with the announced closure of Luxfer Gas Cylinders France, including one-time employee benefits, asset write-downs and associated legal and professional fees.

The $0.7 million restructuring charge in 2018 was the result of:

• $0.2 million in relation to termination costs within the Gas Cylinders segment;

• $0.4 million of termination costs and a property impairment charge related to the rationalization of Elektron's Graphic Arts operations; and

• $0.1 million related to a previously announced plant closure affecting Elektron's Magtech business unit.

Impairment charges

The impairment credit of $0.2 million in 2019 reflects a fair value adjustment to the held-for-sale assets in the Elektron segment.

24

Acquisition-related costs

Acquisition-related costs of $4.6 million in 2019 relate to a $3.5 million termination payment and our professional and legal fees incurred in connection with the aborted acquisition of Neo Performance Materials.

Net interest expense

The 26.7% reduction in net interest expense in 2019 from 2018 was due to the reduction in the average debt balance in 2019 resulting in lower interest costs, following the repayment of $15.0 million private placement debt when due, in June 2018.

Defined benefit pension credit

The $0.8 million decrease in defined benefit pension credit to $0.6 million in 2019 from $1.4 million in 2018 is primarily due to lower projected asset returns in 2019.

Provision for income taxes

The movement in the statutory effective tax rate from 23.6% in 2018, to negative 131.3% in 2019, was primarily due to non-deductible expenses related to the aborted acquisition and restructuring activities. When stripping out the affect of these expenses, our adjusted effective tax rate has fallen from 23.7% in 2018, to 20.0% in 2019.

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 qualifying restructuring charges; impairment charges; legal expenses incurred from patent litigation with a competitor; profit on sale of redundant site acquisition-related charges / credits; loss on disposal of property, plant and equipment; depreciation and amortization; share based compensation expense; 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	2019			2018			2019 v 2018
Net sales	$	58.4		$	59.3		(1.5	)%
Adjusted EBITDA	4.5			6.0			(25.0	)%
% of net sales	7.7		%	10.1		%	(2.4	)

Net sales

The 1.5% decrease in Gas Cylinders sales in 2019 from 2018 was primarily the result of:

• Decreased sales of SCBA cylinders

• Decreased sales of aluminum cylinders

• These decreases were partially offset by increased sales of AF cylinders.

• Superform sales were flat.

Adjusted EBITDA

The 2.4 percentage point decrease in adjusted EBITDA for Gas Cylinders as a percentage of net sales in 2019 from 2018 was primarily the result of productivity challenges at Luxfer Gas Cylinders France (as explained above).

27

ELEKTRON

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

	First Quarter						% / point change
In millions	2019			2018			2019 v 2018
Net sales	$	62.0		$	60.4		2.6	%
Adjusted EBITDA	14.0			13.2			6.1	%
% of net sales	22.6		%	21.9		%	0.7

Net sales

The 2.6% increase in Elektron sales in 2019 from 2018 was primarily the result of increased sales of zirconium-based industrial and automotive catalysts.

These increases were partially offset by:

•Decreased shipments of magnesium-based disaster-relief products; and

•Lower sales of graphic arts products.

Adjusted EBITDA

The 0.7 percentage point increase in adjusted EBITDA for Elektron as a percentage of net sales in 2019 from 2018 was primarily the result of:

• Improved product mix driven primarily by growth of zirconium-based catalysis sales, but partially offset by decline in Luxfer Magtech disaster relief sales;

• Continued reduction in operational costs as part of our transformation plan, but partially offset by productivity challenges in Luxfer Graphic Arts due to plant consolidation.

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. For example, in 2017, we acquired the trade and assets of the Specialty Metals business of ESM Group Inc., including a manufacturing facility in Saxonburg, PA.

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 Loan Notes and the Senior Facilities Agreement throughout all of the quarterly measurement dates from and including September 30, 2011, to March 31, 2019.

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

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

Cash Flows

Operating activities

Cash used in operating activities was $7.8 million in 2019. It was primarily related to net loss from operating activities, net of the following non-cash items: depreciation and amortization; asset impairment credit, pension contributions and net changes to assets and liabilities.

Cash provided by operating activities was $8.3 million in 2018. 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 by investing activities was $3.2 million in 2019, compared to net cash used for investing activities of $1.2 million in 2018. The movement was primarily due to an increase in capital expenditures which were $3.2 million and $1.3 million, in 2019, and 2018, respectively. We anticipate capital expenditures for fiscal 2019 to be approximately $20 million.

Financing activities

In 2019, net cash provided from financing activities was $11.2 million (2018: $12.2 million outflow). We made net drawdowns on our banking facilities of $15.5 million (2018: $8.2 million repayment) and dividend payments of $3.4 million (2018: $3.4 million), equating to $0.125 per ordinary share. We also received $1.4 million (2018: nil) in relation to proceeds from sales of shares.

Capital Resources

Dividends

We paid dividends in 2019 of $3.4 million (2018: $3.4 million), or $0.50 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 U.S. 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.

29

Contractual obligations

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

	Payments Due by Period

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 2018 Annual Report on Form 10-K, filed with the SEC on March 11, 2019, 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, there is a critical accounting policy in relation to Leases, see Note 1 of the Notes to Condensed Consolidated Financial Statements.

30

Item 3.        Quantitative and qualitative disclosures about market risk

There have been no material changes in our market risk during the quarter ended March 31, 2019. For additional information, refer to Item 7A of our 2018 Annual Report on Form 10-K, filed with the SEC on March 11, 2019.

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 31, 2019, 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 the reasonable assurance level, as of the end of the quarter ended March 31, 2019, 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 31, 2019, 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

While we are involved from time to time in claims and legal proceedings that result from, and are incidental to, the conduct of our business including business and commercial litigation, employee and product liability claims, there are no material pending legal proceedings to which the Company or any of its subsidiaries is a party, or of which any of their property is subject. It is possible, however, that an adverse resolution of an unexpectedly large number of such individual claims or proceedings could in the aggregate have a material adverse effect on results of operations for a particular year or quarter.

Item 1A.    Risk Factors

There have been no material changes from the risk factors previously disclosed in Item 1A. of our 2018 Annual Report on Form 10-K, except that the U.K.'s exit ('Brexit') from the European Union (E.U.) has been further deferred by the E.U. until October 31, 2019, with the possibility of an earlier exit should that be approved by the U.K. parliament. However, the risk factors under the caption "Our global operations expose us to economic conditions, potential tax costs, political risks and specific regulations in the countries in which we operate" previously disclosed in Item 1A. of our 2018 Annual Report on Form 10-K relating to Brexit, remain applicable.

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 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, except for the adoption for Accounting Standards Codification ("ASC") Topic 842, "Leases". 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, 2018. 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, 2019, ended March 31, 2019, and the First Quarter, 2018, ended April 1, 2018.

Adoption of new accounting standards

On January 1, 2019, we adopted ASC Topic 842, "Leases", and applied the modified retrospective approach to recognizing any right-of-use assets and lease liabilities. Upon adoption, we have recognized all of our leases greater than one-year in duration and greater than $5,000 fair value, on the balance sheet as right-of-use assets and lease liabilities. This has resulted in us restating the prior period comparatives and have recognized a right-of-use asset of $21.2 million at January 1, 2018, with a corresponding lease liability, split $3.1 million, recognized in Other current liabilities, and $18.1 million recognized in Other non-current liabilities. Classification as either operating or finance is based on criteria largely similar to those applied in ASC 840 but without explicit bright lines. We have made certain assumptions in judgments when applying ASC 842, those judgments of most significance are as follows:

• We elected the package of practical expedients available for transition which allow us to not reassess:

◦ Whether expired or existing contracts contain leases under the new definition of a lease;

◦ Lease classification for expired or existing leases; and

◦ Whether previously capitalized initial direct costs would qualify for capitalization under ASC 842.

• We did not elect to use hindsight for transition when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset.

• We did not elect to reassess whether land easements meet the definition of a lease if they were not accounted for as leases under the former rules.

• For all asset classes, we elected to not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less.

• For all asset classes, we elected to not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component.

1.    Basis of Presentation and Responsibility for interim Financial Statements (continued)

We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheet as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Some of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use.

In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various tenors (ranging from one-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments.

The standard had no impact on our results of operations or cash flows. In addition, new disclosures are provided to enable users to assess the amount, timing and uncertainty of cash flows arising from leases.

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	2019			2018
Basic earnings:
Net (loss) / income	$	(3.8	)	$	9.9
Weighted average number of £0.50 ordinary shares:
For basic earnings per share	27,032,677			26,512,765
Dilutive effect of potential common stock	—			385,118
For diluted earnings per share	27,032,677			26,897,883
(Loss) / earnings per share using weighted average number of ordinary shares outstanding:
Basic (loss) / earnings per ordinary share	$	(0.14	)	$	0.37
Diluted (loss) / earnings per ordinary share	$	(0.14	)	$	0.37

In the first quarter of 2019, basic average shares outstanding and diluted average shares outstanding were the same because the effect of potential shares of common stock was anti-dilutive since the Company generated a net loss. As a result, 735,730 combined were not included in the computation of diluted EPS.

The Company’s performance obligations are satisfied over time as work progresses or at a point in time. Design and tooling arrangements are the only contracts for which sales are recognized over time. Sales from these sources combined accounted for less than 3% of the Company’s sales for the quarters ended March 31, 2019, and April 1, 2018. All consideration from contracts with customers is included in these amounts.

The following table provides information about contract receivables, contract assets and contract liabilities from contracts with customers:

Contract receivables	$	1.9		$	1.5

Restructuring

Restructuring

During the First Quarter of 2019 and the year ended December 31, 2018, we initiated and continued execution of certain business restructuring initiatives aimed at reducing our fixed cost structure and realigning our business. Initiatives during the First Quarter of 2019 were predominantly in relation to the continued consultation to close the Gas Cylinders segment's French site. There is an expectation that further costs will be incurred during 2019.

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

	First Quarter

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives and Financial Instruments

Derivatives and Financial Instruments

The Company's financial instruments comprise bank and other loans, senior loan notes, derivatives, trade payables deferred and deferred contingent consideration. Other than derivatives, the main purpose of these financial instruments is to raise finance for the Company's operations. The Company also has various financial assets such as trade receivables and cash and cash equivalents, which arise directly from its operations.

Derivative financial instruments                                        We are exposed to market risk during the normal course of business from changes in currency exchange rates, interest rates and commodity prices such as aluminum prices. We manage exposures through a combination of normal operating and financing activities and through the use of derivative financial instruments such as foreign currency forward purchase contracts and aluminum forward purchase contracts. We do not use market risk-sensitive instruments for trading or speculative purposes. The Company had $0.3 million and $0.1 million derivative financial instruments disclosed within Accounts and other receivables as of March 31, 2019 and December 31, 2018, respectively. There were also $0.2 million and nil derivative financial instruments recorded in Other current liabilities at March 31, 2019, and December 31, 2018, respectively.

The fair value of forward foreign currency exchange contracts deferred in equity was a loss of $0.6 million and a loss of $0.4 million at March 31, 2019, and December 31, 2018, respectively. During the First Quarter of 2019, $0.2 million was transferred to the Income Statement.

Forward foreign currency exchange contracts                                    The Company incurs currency transaction risk whenever one of the Company's operating subsidiaries enters into either a purchase or sales transaction in a currency other than its functional currency. Currency transaction risk is reduced by matching sales and expenses in the same currency. The Company's U.S. operations have little currency exposure, as most purchases, costs and sales are conducted in U.S. dollars. The Company's U.K. operations are exposed to exchange transaction risks, mainly because these operations sell goods priced in euros and U.S. dollars, and purchase raw materials priced in U.S. dollars and its functional currency is GBP sterling. The Company also incurs currency transaction risk if it lends currency other than its functional currency to one of its joint venture partners.

At March 31, 2019, and December 31, 2018, the Company held various forward foreign currency exchange contracts designated as hedges in respect of forward sales for U.S. dollars, euros and Australian dollars for the receipt of GBP sterling or euros. The Company also held forward foreign currency exchange contracts designated as hedges in respect of forward purchases for U.S. dollars by the sale of GBP sterling. The contract totals in GBP sterling and euros, range of maturity dates and range of exchange rates are disclosed below, with the value denominated in GBP sterling given that is the currency the majority of the contracts are held in.

9.    Derivatives and Financial Instruments (continued)

Fair value of financial instruments                                        

The following methods were used to estimate the fair values of each class of financial instrument:

Cash at bank and in hand / overdrafts                                        The carrying value approximates to the fair value as a result of the short-term maturity of the instruments. Cash at bank and in hand are subject to a right to offset in the U.S.

Bank loans                                                    Bank and other loans, excluding overdrafts, of $86.3 million were outstanding at March 31, 2019, and $75.0 million were outstanding at December 31, 2018. Bank and other loans are shown net of issue costs of $1.3 million and $1.4 million at March 31, 2019, and December 31, 2018, respectively, and are to be amortized to the expected maturity of the facilities. Of the bank and other loans outstanding, $11.3 million and none is variable interest rate debt and subject to floating interest rate risk, with the remainder being fixed rate debt, at March 31, 2019, and December 31, 2018, respectively.

Forward foreign currency exchange rate contracts                                The fair value of these contracts was calculated by determining what the Company would be expected to receive or pay on termination of each individual contract by comparison to present market prices.

LME derivative contracts                                            The fair value of these contracts has been calculated by valuing the contracts against the equivalent forward rates quoted on the LME.

Deferred contingent consideration

The deferred contingent consideration is in relation to the acquisition of Truetech and Innotech (Luxfer Magtech) in 2014 and is linked to the future profitability of the entity.

The Company uses the following hierarchy for determining and disclosing the fair value of financial instruments by valuation technique:

Level 1: quoted (unadjusted) prices in active markets for identical assets or liabilities.

Level 2: other techniques for which all inputs which have a significant effect on the recorded fair value are observable, either directly or indirectly.

Level 3: techniques which use inputs which have a significant effect on the recorded fair value that are not based on observable market data.

The fair values of the financial instruments of the Company at March 31, 2019, were analyzed using the hierarchy as follows:

In millions	Total			Level 1		Level 2			Level 3
Derivative financial assets:
Foreign currency contract assets	$	0.3		$	—	$	0.3		$	—

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 First Quarter ended March 31, 2019, was negative 131%, compared to 23.6% for the First Quarter ended April 1, 2018. The 2019 rate was adversely affected by the impact of non-deductible expenses related to the aborted acquisition of Neo Performance Materials and restructuring activities. We continue to actively pursue initiatives to reduce our effective tax rate. The tax rate in any quarter can be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Act”) was signed into law making significant changes to the U.S. Internal Revenue Code. Changes include, but are not limited to, a corporate tax rate decrease from 35% to 21% effective for tax years beginning after December 31, 2017, the transition of U.S. international taxation from a worldwide tax system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings as of December 31, 2017. For 2018, the Company considered in its estimated annual effective tax rate additional provisions of the Act including changes to the deduction for executive compensation and interest expense, a tax on global intangible low-taxed income provisions (“GILTI”), the base erosion anti-abuse tax, and a deduction for foreign-derived intangible income. The Company has elected to treat tax on GILTI income as a period cost and has therefore included it in its annual estimated effective tax rate.

In March 2019, 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 200,000 and the weighted-average fair value of options granted in 2019 was estimated to be $17.70 per share.

The following table illustrates the assumptions used in deriving the fair value of share options granted during the First Quarter of 2019 and the year-ended December 31, 2018,:

	2019	2018
Dividend yield (%)	4.00	4.00
Expected volatility range (%)	22.65 - 35.77	22.65 - 35.77
Risk-free interest rate (%)	0.12 - 2.57	0.12 - 2.57

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

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

Segment Reporting [Abstract]

Segmental Information

Segmental Information

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

Gas Cylinders segment

Our Gas Cylinders segment manufactures and markets specialized products using aluminum, titanium and carbon composites, 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. The segment also forms lightweight aluminum and titanium panels into highly complex shapes that are used mainly in the transportation industry.

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 expense; qualifying restructuring charges; impairment charges; legal expenses incurred from patent litigation with a competitor; profit on sale of redundant site; acquisition-related charges / credits; loss on disposal of property, plant and equipment; depreciation and amortization; and unwind of 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 First Quarter ended March 31, 2019, and April 1, 2018, is included in the following summary:

Commitments and Contingencies

Commitments and Contingencies

Committed banking facilities

At March 31, 2019, and December 31, 2018, the Company had committed banking facilities of $150.0 million. The facilities were for providing loans and overdrafts, with a separate facility for letters of credit which at March 31, 2019, was £7.0 million ($9.1 million) and December 31, 2018, was £7.0 million ($8.9 million). Of the committed facilities, $7.6 million was drawn for overdrafts, no loans were drawn and no letters of credit were utilized at March 31, 2019, $3.5 million, nil and nil at December 31, 2018. The Company also has a separate bonding facility for bank guarantees denominated in GBP sterling of £3.0 million (2019: $3.9 million, 2018: $3.8 million), of which $1.0 million ($1.4 million) was utilized at March 31, 2019, and December 31, 2018, respectively.

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 minor injuries such as loss of hearing. There was no major damage to assets of the customer. A claim was launched by the three people who were injured in the incident and a prosecutor has been appointed. We had reviewed our quality control checks from around the time which the cylinder was produced and no instances of failures were 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.

Basis of Presentation and Responsibility for interim Financial Statements (Policies)

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of presentation

We prepared the accompanying unaudited consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements, except for the adoption for Accounting Standards Codification ("ASC") Topic 842, "Leases". 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, 2018. 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, 2019, ended March 31, 2019, and the First Quarter, 2018, ended April 1, 2018.

Adoption of new accounting standards and Accounting standards issued but not yet effective

Adoption of new accounting standards

On January 1, 2019, we adopted ASC Topic 842, "Leases", and applied the modified retrospective approach to recognizing any right-of-use assets and lease liabilities. Upon adoption, we have recognized all of our leases greater than one-year in duration and greater than $5,000 fair value, on the balance sheet as right-of-use assets and lease liabilities. This has resulted in us restating the prior period comparatives and have recognized a right-of-use asset of $21.2 million at January 1, 2018, with a corresponding lease liability, split $3.1 million, recognized in Other current liabilities, and $18.1 million recognized in Other non-current liabilities. Classification as either operating or finance is based on criteria largely similar to those applied in ASC 840 but without explicit bright lines. We have made certain assumptions in judgments when applying ASC 842, those judgments of most significance are as follows:

• We elected the package of practical expedients available for transition which allow us to not reassess:

◦ Whether expired or existing contracts contain leases under the new definition of a lease;

◦ Lease classification for expired or existing leases; and

◦ Whether previously capitalized initial direct costs would qualify for capitalization under ASC 842.

• We did not elect to use hindsight for transition when considering judgments and estimates such as assessments of lessee options to extend or terminate a lease or purchase the underlying asset.

• We did not elect to reassess whether land easements meet the definition of a lease if they were not accounted for as leases under the former rules.

• For all asset classes, we elected to not recognize a right-of-use asset and lease liability for leases with a term of 12 months or less.

• For all asset classes, we elected to not separate non-lease components from lease components to which they relate and have accounted for the combined lease and non-lease components as a single lease component.

1.    Basis of Presentation and Responsibility for interim Financial Statements (continued)

We determine if an arrangement is a lease at inception. Operating leases are included in our Consolidated Balance Sheet as Right-of-use assets from operating leases, Current operating lease liabilities and Long-term operating lease liabilities. Some of our lease agreements contain renewal options; however, we do not recognize right-of-use assets or lease liabilities for renewal periods unless it is determined that we are reasonably certain of renewing the lease at inception or when a triggering event occurs. Some of our lease agreements contain rent escalation clauses (including index-based escalations), rent holidays, capital improvement funding or other lease concessions. We recognize our minimum rental expense on a straight-line basis based on the fixed components of a lease arrangement. We amortize this expense over the term of the lease beginning with the date of initial possession, which is the date we enter the leased space and begin to make improvements in preparation for its intended use.

In determining our right-of-use assets and lease liabilities, we apply a discount rate to the minimum lease payments within each lease agreement. ASC 842 requires us to use the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. When we cannot readily determine the discount rate implicit in the lease agreement, we utilize our incremental borrowing rate. To estimate our specific incremental borrowing rates over various tenors (ranging from one-year through 30-years), a comparable market yield curve consistent with our credit quality was calibrated to our publicly outstanding debt instruments.

The standard had no impact on our results of operations or cash flows. In addition, new disclosures are provided to enable users to assess the amount, timing and uncertainty of cash flows arising from leases.
