BEVERLY, Mass., July 11, 2017 /PRNewswire/ -- Axcelis Technologies, Inc. (NASDAQ: ACLS), a leading supplier of innovative, high-productivity solutions for the semiconductor industry, announced today that it has received multiple follow on orders for Purion H™ high current and Purion XE™ high energy systems from several leading memory chip manufacturers. In addition, the Company successfully completed an evaluation for the Purion H high current implanter and received initial follow on orders. These systems will support high volume production of DRAM, 3D NAND and nonvolatile memory devices. Several of these systems shipped in the second quarter and the rest are scheduled to ship over the remainder of the year.

Executive Vice President, Customer Operations John Aldeborgh commented, "We're very pleased to announce these new wins for the Purion platform. They provide additional evidence of continued Purion strength in the memory market. This market is very strong, with the DRAM segment robust and NAND at the beginning of a long term build cycle driven by growth in cloud computing."

President and CEO Mary Puma commented, "Strong adoption of all three Purion products has been the key driver of our growth this year. We currently expect second half revenues to be similar to the first half, resulting in total 2017 revenues of between $360 million and $380 million. 2017 market share is expected to be between 25 and 28 percent. We are also reiterating our second quarter 2017 revenue guidance of approximately $100 million and expect earnings per share to be at the high end of the range of $0.30-0.35."
