BEVERLY, Mass., Nov. 4, 2025 -- Axcelis Technologies, Inc. (Nasdaq: ACLS) today announced financial results for the third quarter ended September 30, 2025.

President and CEO Russell Low commented, "We delivered another solid quarter, with sales and earnings both exceeding our expectations. We are also pleased to report record CS&I revenue in the quarter, reflecting the success of our aftermarket strategy and the continued expansion of our installed base. We are executing on our product development roadmap and customer engagement initiatives with focus and urgency, while maintaining disciplined cost controls. These actions have enabled us to successfully navigate the anticipated cyclical digestion period across our markets in 2025."

Low added, "We entered the fourth quarter with a solid financial foundation and are well poised to execute on our strategy as we enter into our next chapter of growth and innovation. Our recently announced merger with Veeco Instruments marks a critical milestone that we believe will position the combined company to capitalize on powerful secular tailwinds including AI and electrification. By bringing our two companies together, we believe we are building a leading semiconductor equipment company with the capabilities, resources and financial foundation to drive sustainable growth and value creation for shareholders and deliver meaningful benefits to all stakeholders."

Executive Vice President and Chief Financial Officer Jamie Coogan stated, "We generated robust operating leverage through higher volume and disciplined cost management, translating into strong free cash flow. With over $590 million in cash and investments on the balance sheet, Axcelis has ample flexibility to capitalize on our value-enhancing strategic initiatives and long-term growth priorities."

Business Outlook
For the fourth quarter ending December 31, 2025, Axcelis expects revenues of approximately $215 million, GAAP earnings per diluted share of approximately $0.76, and non-GAAP earnings per share of approximately $1.12.

These statements, which include our expectations for spending in our industry and guidance for future financial performance, are based on management's current expectations and should be viewed with caution. They are subject to various risks and uncertainties that could cause actual results to differ materially from those in the forward-looking statements, many of which are outside the control of the Company, including that customer decisions to place orders or our product shipments may not occur when we expect, that orders may not be converted to revenue in any particular quarter, or at all, whether demand will continue for the semiconductor equipment we produce or, if not, whether we can successfully meet changing market requirements, and whether we will be able to maintain continuity of business relationships with and purchases by major customers and, with respect to the potential transaction with Veeco, failure to obtain applicable regulatory or stockholder approvals in a timely manner or otherwise; failure to satisfy other closing conditions to the proposed transaction or to complete the proposed transaction on anticipated terms and timing; negative effects of the announcement of the proposed transaction; risks that the businesses will not be integrated successfully or that the combined company will not realize expected benefits, cost savings, accretion, synergies and/or growth, or that such benefits may take longer to realize or may be more costly to achieve than expected; the risk that disruptions from the proposed transaction will harm business plans and operations; risks relating to unanticipated costs of integration; significant transaction and/or integration costs, or difficulties in connection with the proposed transaction and/or unknown or inestimable liabilities; restrictions during the pendency of the proposed transaction that may impact the ability to pursue certain business opportunities or strategic transactions; potential litigation associated with the proposed transaction; the potential impact of the announcement or consummation of the proposed transaction on the Company's, Veeco's or the combined company's relationships with suppliers, customers, employees and regulators; and demand for the combined company's products. Actual results may differ materially from those projected in such statements due to various factors, including but not limited to: economic, political and social conditions in the countries in which the Company and Veeco, their respective customers and suppliers operate; disruption to the Company's and Veeco's respective manufacturing facilities or other operations, or the operations of Company's and Veeco's respective customers and suppliers, due to natural catastrophic events, health epidemics or terrorism; ongoing changes in the technology industry, and the semiconductor industry in particular, including future growth rates, pricing trends in end-markets, or changes in customer capital spending patterns; the Company's, Veeco's and the combined company's ability to timely develop new technologies and products that successfully anticipate or address changes in the semiconductor industry; the Company's, Veeco's and the combined company's ability to maintain their respective technology advantage and protect their respective proprietary rights; the Company's, Veeco's and the combined company's ability to compete with new products introduced by their respective competitors; the Company's, Veeco's and the combined company's ability or the ability of their respective customers to obtain U.S. export control licenses for the sale of certain products or provision of certain services to customers in China.
