Axcelis Technologies Announces a CFO Transition

Beverly, Massachusetts, March 12, 2026 — Axcelis Technologies, Inc. (Nasdaq: ACLS) has announced a strategic leadership transition within its financial department. David Ryzhik, Senior Vice President of Investor Relations and Corporate Strategy, has been appointed as the Interim Chief Financial Officer effective immediately. This move comes as James Coogan, the incumbent CFO, departs the company to pursue a new opportunity outside the semiconductor industry. Coogan will continue in his role until April 24, ensuring a seamless transition during this critical period.

The announcement was made by President and CEO Russell Low, who expressed confidence in Ryzhik’s capability to fill this vital role. “We are fortunate to have a leader like David available to step into the role of Interim CFO,” said Low. He highlighted Ryzhik’s deep understanding of the company’s business, financial operations, and investor relations, positioning him well to steer the finance organization through this transition and capitalize on opportunities arising from Axcelis’ impending merger with Veeco.

In his new role, Ryzhik aims to continue the momentum at Axcelis, focusing on executing corporate strategies and improving integration planning with Veeco. “I am honored to step into the Interim CFO role and intend to continue building on the momentum underway at Axcelis,” Ryzhik stated. He emphasized the importance of driving long-term shareholder value during his tenure.

Coogan’s departure marks the end of a significant chapter for Axcelis, as he has played a key role in building a robust finance organization and enhancing operational discipline since his appointment. “It has been a privilege to work alongside talented colleagues at Axcelis.
