AXCELIS ANNOUNCES FINANCIAL RESULTS
FOR SECOND QUARTER 2007

BEVERLY, Mass. — August 1, 2007 — Axcelis Technologies, Inc. (Nasdaq: ACLS) today announced financial results for the second quarter ended June 30, 2007. The Company reported revenues of $110.1 million, compared to $97.5 million for the first quarter of 2007. Net income for the second quarter was $4.7 million, or $0.05 per share, compared to net income for the first quarter of 2007 of $2.7 million, or $0.03 per share. In the corresponding quarter for the previous year, the Company reported revenues of $117.6 million and net income of $12.1 million, or $0.12 per share.

Commenting on the Company’s performance, Chairman and CEO Mary Puma said, “We continue to receive positive feedback from customers on advanced technology development and production manufacturing being run on our Optima HD, despite the softening industry conditions. We are confident that continued progress will drive growth of our high dose implant business as we secure additional orders through design wins and capacity buys. Additionally, we were able to win another high volume capacity order for our dry strip products, strengthening our position in the cleaning space.  We look forward to this trend continuing.”
