Sales of $96.0 million increased 9.3 percent year over year, demonstrating solid demand in key markets. This contributed to adjusted earnings per share of $0.29 and enabled us to exceed our full-year financial targets, with full year EPS of $0.99. Strong financial performance also allowed us to generate significant cash flow and greatly reduce net debt. While challenges persist in auto catalysis and Industrial end markets, growth in Defense, First Response and Healthcare continues to drive positive momentum, and we have capitalized on higher demand for Flares and Flameless Ration Heaters, reinforcing our ability to adapt and deliver value in evolving market conditions. Looking ahead, we expect a relatively stable performance in 2025 as we navigate near-term headwinds in clean energy and macroeconomic uncertainties including tariffs. Our disciplined execution, focus on operational efficiency, and leadership in critical end markets position us well to drive long-term value for our customers and shareholders.

This growth was driven by an $8.6 million improvement in volume/mix, partially offset by a $0.7 million negative impact from lower pricing and a $0.4 million negative impact from foreign exchange rates. Additionally, certain defense customers requested expedited order fulfillment in the fourth quarter of approximately $3.4 million, pulling shipments forward from the first quarter of 2025. This contributed to a robust Q4 performance, resulting in higher sales volumes and bolstered margins. GAAP net income from continuing operations was $3.3 million, or $0.12 per diluted share, compared to a net loss of $6.5 million, or loss of $0.24 per diluted share, in the fourth quarter of 2023. Adjusted net income (excluding Graphic Arts) was $8.4 million, or $0.31 per diluted share, compared to $3.6 million, or $0.13 per diluted share, in the fourth quarter of 2023. Excluding net legal expense recovery in the quarter, adjusted net income (excluding Graphic Arts) was $8.0 million, or $0.29 per diluted share, compared to $4.8 million, or $0.18 per diluted share, in the prior year period. Adjusted EBITDA (excluding Graphic Arts) increased to $14.3 million, 76.5% improvement compared to $8.1 million in the prior year. This growth was primarily driven by a $2.9 million positive impact from improved volume/mix, a $3.0 million benefit from net cost deflation (mainly magnesium), and a $1.9 million net benefit from legal expense / cost recovery. These gains were partially offset by a $0.7 million impact from lower prices, $0.6 million in adverse cost movements and a $0.3 million negative impact from foreign exchange during the quarter.

Free cash flow from continuing operations was $30.0 million, an increase of $15.9 million over the same period last year. Full year free cash flow from continuing operations was $47.7 million, an increase of $30.9 million over the prior year and included approximately $13 million of non-recurring inflows from legal cost recovery and the sale of land. As of December 31, 2024, net debt totaled $41.0 million, resulting in a net debt-to-adjusted EBITDA ratio of 0.8x. Excluding Graphic Arts, the net debt-to-adjusted EBITDA ratio was 0.7x. During the fourth quarter of 2024, approximately $0.7 million of common stock, equating to 50,000 shares, was repurchased. In the full year 2024 a total of approximately $2.3 million in common stock, or 200,000 shares, has been repurchased. Additionally, $3.5 million was returned to shareholders through dividends during the quarter, bringing the full year 2024 total to $14.0 million.

Non-GAAP Financial Measures Luxfer Holdings PLC prepares its financial statements using U.S. Generally Accepted Accounting Principles (GAAP). When a company discloses material information containing non-GAAP financial measures, SEC regulations require that the disclosure include a presentation of the most directly comparable GAAP measure and a reconciliation of the GAAP and non-GAAP financial measures. Management’s inclusion of non-GAAP financial measures in this release is intended to supplement, not replace, the presentation of the Company’s financial results in accordance with GAAP. Luxfer management believes that these non-GAAP financial measures, when considered together with the GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any period. Management also believes that these non-GAAP financial measures enhance the ability of investors to analyze the Company’s business trends and understand the Company’s performance. In addition, management may utilize non-GAAP financial measures as a guide in the Company’s forecasting, budgeting, and long-term planning process. Non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures presented in accordance with GAAP. With respect to the Company’s 2025 adjusted earnings per share guidance, the Company is not able to provide a reconciliation of the non-GAAP financial measure to GAAP because it does not provide specific guidance for the various extraordinary, nonrecurring, or unusual charges and other certain items. These items have not yet occurred, are out of the Company’s control, and/or cannot be reasonably predicted. As a result, reconciliation of the non-GAAP guidance measure to GAAP is not available without unreasonable effort, and the Company is unable to address the probable significance of the unavailable information. Forward-Looking Statements This release contains certain forward-looking statements that involve risks and uncertainties that could cause actual results to differ materially from those projected in the forward-looking statements. Examples of such forward-looking statements include but are not limited to: (i) statements regarding the Company’s results of operations and financial condition; (ii) statements of plans, objectives or goals of the Company or its management, including those related to financing, products, or services; (iii) statements of future economic performance; and (iv) statements of assumptions underlying such statements. Words such as “believes,” “anticipates,” “expects,” “intends,” “forecasts,” and “plans,” and similar expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. By their very nature, forward- looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that the predictions, forecasts, projections, and other forward-looking statements will not be achieved. The Company cautions that several important factors could cause actual results to differ materially from the plans, objectives, expectations, estimates, and intentions expressed in such forward-looking statements.

Forward-Looking Statements (con’t) comply with the covenants contained therein. The Company cautions that the foregoing list of important factors are not exhaustive. These factors are more fully discussed in the sections entitled “Forward-Looking Statements” and “Risk Factors” in its Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the U.S. Securities and Exchange Commission on February 25, 2025. When relying on forward-looking statements to make decisions with respect to the Company, investors and others should carefully consider the foregoing factors and other uncertainties and events.
