Materion Corporation (NYSE:MTRN) today reported third-quarter 2025 financial results and affirmed full year outlook.

Financial Summary

Net sales were $444.8 million; value-added sales¹ were $263.9 million
Net income of $25.4 million, or $1.22 per share, diluted, versus net income of $22.3 million, or $1.07 per share, in the prior year quarter; adjusted earnings of $1.41 per share versus $1.41 in the prior year quarter
Operating profit of $34.9 million versus operating profit of $31.3 million in the prior year quarter; adjusted EBITDA² of $55.5 million, versus $56.7 million in the prior year quarter

Business Highlights

Delivered record EBITDA margins of 27.1% in Electronic Materials, up 700 basis points year on year
Precision Optics transformation led to significant step up in sales with approximately 1000 basis points of margin expansion year on year
Order rates up double-digit sequentially with increases across all three businesses, driven by organic initiatives and strong macroeconomic trends
Announced supply agreement with Commonwealth Fusion Systems, the leading and largest commercial fusion energy company, to provide materials for groundbreaking fusion technologies
Board of Directors authorized a new $50 million stock repurchase program, replacing existing stock repurchase program

"I am incredibly proud of our team's performance in the third quarter, with both Electronic Materials and Precision Optics achieving significant milestones. The record margin performance in Electronic Materials underscores the substantial improvements we've made in that business, as our semiconductor sales start to rebound on a much-improved cost structure. In addition, the Precision Optics transformation is delivering ahead of our expectations with a significant step up in sales in the quarter, and a return to double digit EBITDA margins," said Jugal Vijayvargiya, President & CEO of Materion.

"As we look ahead, we are encouraged by the increasing order rates in each of our business segments, specifically in markets impacted by strong macro trends, including semiconductor, energy, space and defense. Our deep customer partnerships and broad portfolio of critical advanced materials position us well to close out a strong 2025 and seed the pipeline for future growth."

THIRD QUARTER 2025 RESULTS

Net sales for the quarter were $444.8 million, compared to $436.7 million in the prior year period. Value-added sales were $263.9 million for the quarter, up 1% organic³ from the prior year quarter due to strength in non-China semiconductor and space, partially offset by equipment downtime at a Performance Materials facility impacting sales output.

Operating profit for the quarter was $34.9 million and net income was $25.4 million, or $1.22 per diluted share, compared to operating profit of $31.3 million and net income of $22.3 million, or $1.07 per share, in the prior year period.

Adjusted EBITDA was $55.5 million, or 21.0% of value-added sales, compared to $56.7 million or 21.5% of value-added sales in the prior year period. This decrease was driven primarily by equipment downtime within Performance Materials, partially offset by strong price/mix and operational performance in Electronic Materials as well as the improved performance in Precision Optics.

Adjusted net income was $29.4 million excluding acquisition amortization, or $1.41 per diluted share, compared to $1.41 per share in the prior year period.

OUTLOOK

With one quarter remaining in the full year, we expect to deliver a strong fourth quarter and finish 2025 on a high note. With that, we are affirming our prior guide of $5.30 to $5.70 adjusted earnings per share for the full year.

ADJUSTED EARNINGS GUIDANCE

It is not possible for the Company to identify the amount or significance of future adjustments associated with potential insurance and litigation claims, legacy environmental costs, acquisition and integration costs, certain income tax items, or other non-routine costs that the Company adjusts in the presentation of adjusted earnings guidance. These items are dependent on future events that are not reasonably estimable at this time. Accordingly, the Company is unable to reconcile without unreasonable effort the forecasted range of adjusted earnings guidance for the full year to a comparable GAAP range. However, items excluded from the Company's adjusted earnings guidance include the historical adjustments noted in Attachments 4 through 8 to this press release.

The cost of gold, silver, platinum, palladium, copper, ruthenium, iridium, rhodium, rhenium, and osmium is passed through to customers and, therefore, the trends and comparisons of net sales are affected by movements in the market price of these metals. Internally, management also reviews net sales on a value-added basis. Value-added sales is a non-GAAP financial measure that deducts the value of the pass-through metals sold from net sales. Value-added sales allows management to assess the impact of differences in net sales between periods or segments and analyze the resulting margins and profitability without the distortion of the movements in pass-through market metal prices. The dollar amount of gross margin and operating profit is not affected by the value-added sales calculation. The Company sells other metals and materials that are not considered direct pass throughs, and these costs are not deducted from net sales to calculate value-added sales. The Company's pricing policy is to pass the cost of these metals on to customers in order to mitigate the impact of price volatility on the Company's results from operations. Value-added information is being presented since changes in metal prices may not directly impact profitability. It is the Company's intent to allow users of the financial statements to review sales with and without the impact of the pass-through metals.

In addition to presenting financial statements prepared in accordance with U.S. generally accepted accounting principles (GAAP), this earnings release contains financial measures, including operating profit, segment operating profit, earnings before interest, taxes, depreciation, depletion and amortization (EBITDA), net income, and earnings per share, on a non-GAAP basis. As detailed in the above reconciliation and Attachment 6, we have adjusted the results for certain special items, including the following:

Restructuring and cost reduction – Costs include restructuring charges, costs associated with temporarily idled facilities as a result of decreased demand and costs associated with disposal of assets associated with obsolete products. Electronic Materials inventory adjustment – During the third quarter of 2024, the Company determined that material costs from prior years were understated due to unrecognized metal refine expense and other inventory adjustments. Environmental remediation - Cost associated with non-recurring environmental remediation Business transformation costs – Represents project management and implementation expenses related to the Company's automation and transformation initiatives. Additional start up resources and scrap – Represents incremental resource, consulting and specialists costs incurred related to the ramp of the precision clad strip facility and scrap related to product qualifications. Merger, acquisition and divestiture related costs – Includes due diligence costs associated with potential merger, acquisition and divestitures as well as loss on asset disposals.

Internally, management reviews the results of operations without the impact of these costs in order to assess the profitability from ongoing activities. We are providing this information because we believe it will assist investors in analyzing our financial results and, when viewed in conjunction with the GAAP results, provide a more comprehensive understanding of the factors and trends affecting our operations.
