Management Comment

Rafi Amit, Camtek’s CEO commented, “Camtek continues to deliver record performance in 2025, with 20% year-over-year growth in revenues and strong gross margins at around the 52% level, contributing to record quarterly operating income. Our ongoing growth continues to be driven primarily by the high-performance computing applications for AI.”

Continued Mr. Amit, “The Advanced Packaging segment is rapidly evolving with technological advancements, to support the requirements of the fast-paced evolution of High-Performance Computers for AI. The market for advanced packaging solutions that enable AI is projected to grow at a rapid rate in the coming years. We anticipate these new requirements to trigger an industry-wide upgrade cycle, fueling demand for next-generation inspection and metrology tools. Our recently introduced Eagle G5 and Hawk systems are built with a view of these new technological requirements and have, to date, been very well received by the market.”

Concluded Mr. Amit, “Looking ahead, in the third quarter we expect to reach our significant milestone and long-term goal of half a billion dollars in revenue, and we continue to have a healthy order flow and pipeline into the fourth quarter. Camtek has become a market leader in its domain. We believe that the new packaging technologies represent major growth opportunities for us in the coming years.”

This press release is available at http://www.camtek.com

This press release contains statements that may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements are based on Camtek’s current beliefs, expectations and assumptions about its business and industry, all of which may change. Forward-looking statements can be identified by the use of words including “believe,” “anticipate,” “should,” “intend,” “plan,” “will,” “may,” “expect,” “estimate,” “project,” “positioned,” “strategy,” and similar expressions that are intended to identify forward-looking statements, including our expectations and statements relating to the compound semiconductors market and our position in this market and the anticipated timing of delivery of the systems. These forward-looking statements involve known and unknown risks and uncertainties that may cause the actual results, performance or achievements of Camtek to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Factors that may cause our actual results to differ materially from those contained in the forward-looking statements include, but are not limited to, the effects of the evolving nature of the war situation in Israel, and the related evolving regional conflicts; the continued demand and future contribution of HPC, HBM and Chiplet applications and devices to the Company business resulting from, among other things, the field of AI surging worldwide across companies, industries and geographies; formal or informal imposition by countries of new or revised export and/or import and doing-business regulations or sanctions, including but not limited to changes in U.S. trade policies, changes or uncertainty related to the U.S. government entity list and changes in the ability to sell products incorporating U.S originated technology, which can be made without prior notice, and our ability to effectively address such global trade issues and changes; our dependency on the semiconductor industry and the risk that adverse economic conditions, reduced capital expenditures, or cyclical downturns may negatively impact our results; the concentration of our business in certain Asia Pacific countries, particularly China, Taiwan, and Korea, which may be subject to trade restrictions, regulatory changes, or geopolitical tensions; and those other factors discussed in our Annual Report on Form 20-F as published on March 19, 2025 as well as other documents filed by the Company with the SEC as well as other documents that may be subsequently filed by Camtek from time to time with the Securities and Exchange Commission. We caution you not to place undue reliance on forward-looking statements, which speak only as of the date hereof. Camtek does not assume any obligation to update any forward-looking statements in order to reflect events or circumstances that may arise after the date of this release unless required by law.

While we believe that we have a reasonable basis for each forward-looking statement contained in this press release, we caution you that these statements are based on a combination of facts and factors currently known by us and our projections of the future, about which we cannot be certain. In addition, any forward-looking statements represent Camtek’s views only as of the date of this press release and should not be relied upon as representing its views as of any subsequent date. Camtek does not assume any obligation to update any forward-looking statements unless required by law.

This press release provides financial measures that exclude: (i) share based compensation expenses; and (ii) acquisition related expenses and are therefore not calculated in accordance with generally accepted accounting principles (GAAP). Management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance. The presentation of this non-GAAP financial information is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management uses both GAAP and non-GAAP measures when evaluating the business internally and therefore felt it is important to make these non-GAAP adjustments available to investors. A reconciliation between the GAAP and non-GAAP results appears in the tables at the end of this press release.
