Our third-quarter results demonstrate the earnings power and disciplined execution across our business. We delivered solid profitability and strong cash generation, achieving $0.30 in adjusted EPS and generating more than $10 million in free cash flow. Continued strength in defense and aerospace, together with sharpened focus on our growth priorities, supported another quarter of strong results. We also advanced our strategic priorities, completing the sale of the Graphic Arts business and announcing a new Powders Center of Excellence within our Elektron segment. This initiative will enhance our manufacturing capabilities and is expected to deliver approximately $2 million in annual savings. With one quarter remaining, Luxfer is well positioned to deliver a successful year and enter 2026 with a stronger portfolio and clear focus on driving sustained earnings growth.

Third Quarter Financial Summary GAAP net sales of $92.9 million compared to $99.4 million in the prior-year period, reflecting the absence of sales from the Graphic Arts business, which was divested in early July 2025. Excluding Graphic Arts, adjusted net sales increased 1.6% from the prior year, supported by continued strength in Defense and First Response end markets. The Elektron segment delivered strong results, supported by strong demand in Defense and Aerospace, with elevated magnesium-related sales including UGR-Es, MRE flameless ration heaters and magnesium alloys. Gas Cylinders’ performance tracked with expectations, reflecting typical demand patterns across core SCBA and Specialty Industrial markets, and with continued activity in Space exploration programs. GAAP net income for the third quarter of 2025 was $2.5 million, or $0.09 per diluted share, compared to $12.6 million, or $0.47 per diluted share, in the prior-year period. Adjusted net income, excluding Graphic Arts and 2024 legal recoveries, was $8.1 million, or $0.30 per diluted share, up from $7.1 million, or $0.27 per diluted share, in the third quarter of 2024. Adjusted EBITDA was $13.6 million, compared to $13.5 million in the prior year. Adjusted sales were marginally up and improved mix within Elektron and operational execution supported stable margins and strong earnings. Sequentially, profitability improved despite lower revenue, driven by favorable mix and performance.

Capital Resources and Liquidity Net cash provided by continuing operations for the third quarter of 2025 was $11.8 million, compared to $12.9 million in the prior year period. Free cash flow from continuing operations totaled $10.3 million, excluding proceeds from the sale of Graphic Arts, compared to $9.3 million in the prior year. Net debt was reduced to $37.3 million at the end of the quarter, resulting in a net debt-to-adjusted EBITDA ratio of approximately 0.7x, compared to 1.3x in the prior year. During the third quarter of 2025, approximately $0.8 million of common stock, equating to 65,000 shares, was repurchased. Year-to-date, a total of approximately $1.9 million in common stock, or 155,000 shares, has been repurchased. Additionally, $3.5 million was returned to shareholders through dividends during the quarter, bringing the year-to-date total to $10.5 million. 2025 Guidance Raised Reflecting strong performance from the first three quarters of the year, strength in Defense and Aerospace, combined with operational improvements, is expected to offset softness in certain transportation markets.

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. These factors include but are not limited to: (i) lower than expected future sales; (ii) increasing competitive industry pressures; (iii) general economic conditions or conditions affecting demand for the products and services it offers, both domestically and internationally; (iv) worldwide economic and business conditions and conditions in the industries in which the Company operates; (v) geopolitical issues / tariffs (vi) fluctuations in the cost or availability of raw materials , utilities, and other inputs; (vii) currency fluctuations and hedging risks; (viii) the Company’s ability to protect its intellectual property; and (ix) the significant amount of indebtedness the Company has incurred and may incur and the obligations to service such of indebtedness the Company has incurred and may incur and the obligations to service such indebtedness and to 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. Forward- looking statements speak only as of the date on which they are made, and the Company does not undertake any obligation to update or revise any such statement, whether because of new information, future events, or otherwise.
