**Fourth Quarter Outlook**

For the Company's guidance for the fourth quarter ending December 31, 2025, the Company expects sales of $790 million to $830 million. We expect GAAP net income to be between $53 million and $64 million and diluted earnings per common share is expected to be between $0.35 and $0.42.

The Company also expects Adjusted EBITDA of approximately 26.5% to 27.5% of sales.

The Company currently operates in two segments:

**Materials Solutions (MS):** MS provides materials-based solutions, such as chemical vapor and atomic layer deposition materials, chemical mechanical planarization slurries and pads, ion implantation specialty gases, formulated etch and clean materials, and other specialty materials that enable our customers to achieve better device performance and faster time to yield, while providing for lower total cost of ownership.

**Advanced Purity Solutions (APS):** APS offers filtration, purification and contamination-control solutions that improve customers' yield, device reliability and cost by ensuring the purity of critical liquid chemistries and gases and the cleanliness of wafers and other substrates used throughout semiconductor manufacturing processes, the semiconductor ecosystem and other high-technology industries.

**Non-GAAP Information**

The Company's condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States (GAAP). Adjusted Net Sales, Adjusted EBITDA, Adjusted Gross Profit, Adjusted Segment Profit, Adjusted Operating Income, non-GAAP Net Income, non-GAAP Adjusted Operating Margin and diluted non-GAAP Earnings Per Common Share, together with related measures thereof, are considered "non-GAAP financial measures" under the rules and regulations of the Securities and Exchange Commission. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. The Company provides supplemental non-GAAP financial measures to better understand and manage its business and believes these measures provide investors and analysts additional and meaningful information for the assessment of the Company's ongoing results. Management also uses these non-GAAP measures to assist in the evaluation of the performance of its business segments and to make operating decisions. Management believes that the Company's non-GAAP measures help indicate the Company's baseline performance before certain gains, losses or other charges that may not be indicative of the Company's business or future outlook, and that non-GAAP measures offer a more consistent view of business performance. The Company believes the non-GAAP measures aid investors' overall understanding of the Company's results by providing a higher degree of transparency for such items and providing a level of disclosure that will help investors generally understand how management plans, measures and evaluates the Company's business performance. Management believes that the inclusion of non-GAAP measures provides greater consistency in its financial reporting and facilitates investors' understanding of the Company's historical operating trends by providing an additional basis for comparisons to prior periods. The reconciliations of GAAP net sales to Adjusted Net Sales (excluding divestiture), GAAP gross profit to Adjusted Gross Profit, GAAP segment profit to Adjusted Operating Income, GAAP net income to Adjusted Operating Income and Adjusted EBITDA, GAAP net income and diluted earnings per common share to non-GAAP Net Income and diluted non-GAAP Earnings Per Common Share and GAAP outlook to non-GAAP outlook are included elsewhere in this release.
