Chandler, Arizona, October 29, 2025: Rogers Corporation (NYSE:ROG) today announced financial results for the third quarter of 2025.

"Third quarter results were at the upper end of guidance due to improved end-market demand and good execution on cost improvement initiatives,” stated Ali El-Haj, Rogers' Interim President and CEO. "Compared to the prior quarter sales, gross margin, earnings, adjusted EBITDA and free cash flow all showed substantial improvement."

"Fourth quarter sales and earnings are expected to improve versus the prior year, with typical seasonal patterns leading to a sequential decline. We are executing on critical initiatives to improve growth, reduce manufacturing and operating costs and drive meaningfully improved results for shareholders."

1 - Adjusted Earnings Per Diluted Share, Adjusted EBITDA and Free Cash Flow are non-GAAP measures. A reconciliation of non-GAAP to GAAP

measures is provided in the schedules included below.

Net sales of $216.0 million increased 6.5% versus the prior quarter. Advanced Electronics Solutions (AES) net sales increased by 5.2% primarily related to higher EV/HEV, wireless infrastructure and industrial sales, partially offset by lower ADAS sales. Elastomeric Material Solutions (EMS) net sales increased by 8.7% primarily from stronger portable electronics, aerospace and defense (A&D) and industrial sales, partially offset by lower EV/HEV sales. Currency exchange rates favorably affected total Company net sales in the third quarter of 2025 by $3.0 million compared to the prior quarter.

GAAP earnings per diluted share were $0.48 compared to losses per diluted share of $(4.00) in the previous quarter. The improved earnings resulted from higher sales and gross margin, lower selling general and administrative expenses and a reduction in restructuring and impairment charges. On an adjusted basis, earnings were $0.90 per diluted share compared to earnings of $0.34 per diluted share in the prior quarter.

Ending cash and cash equivalents were $167.8 million, an increase of $10.6 million versus the prior quarter. Net cash provided by operating activities in the third quarter was $28.9 million and capital expenditures were $7.7 million. Share repurchases totaled $10.0 million in the third quarter.

This earnings release includes the following financial measures that are not presented in accordance with generally accepted accounting principles in the United States of America (“GAAP”):

(1) Adjusted earnings per diluted share, which the Company defines as earnings (loss) per diluted share excluding acquisition and related integration costs, dispositions, intangible amortization, (gains) losses on the sale or disposal of property, plant and equipment, restructuring, severance, impairment and other related costs, asbestos-related charges (credits), and the related income tax effect on these items, and charges to income tax expense for valuation allowances on deferred tax assets generated in prior years, divided by adjusted weighted average shares outstanding - diluted;

(2) Adjusted EBITDA, which the Company defines as net income (loss) excluding acquisition and related integration costs, dispositions, intangible amortization, (gains) losses on the sale or disposal of property, plant and equipment, restructuring, severance, impairment and other related costs, asbestos-related charges (credits), interest income (expense), net, income tax (benefit) expense , depreciation of fixed assets, and equity compensation expense;

(3) Adjusted EBITDA Margin, which the Company defines as the percentage that results from dividing Adjusted EBITDA by total net sales;

(4) Free cash flow, which the Company defines as net cash provided by operating activities less non-acquisition capital expenditures.

Management believes adjusted earnings per diluted share, adjusted EBITDA and adjusted EBITDA margin are useful to investors because they allow for comparison to the Company’s performance in prior periods without the effect of items that, by their nature, tend to obscure the Company’s core operating results due to potential variability across periods based on the timing, frequency and magnitude of such items. As a result, management believes that these measures enhance the ability of investors to analyze trends in the Company’s business and evaluate the Company’s performance relative to peer companies. Management also believes free cash flow is useful to investors as an additional way of viewing the Company's liquidity and provides a more complete understanding of factors and trends affecting the Company's cash flows. However, non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation from, or as alternatives to, financial measures prepared in accordance with GAAP. In addition, these non-GAAP financial measures may differ from, and should not be compared to, similarly named measures used by other companies. Reconciliations of the differences between these non-GAAP financial measures and their most directly comparable financial measures calculated in accordance with GAAP are set forth below.

The following table reconciles weighted average shares outstanding - diluted under US GAAP to adjusted weighted average shares outstanding - diluted used in the calculation of adjusted diluted EPS:
