Exhibit 99.1
Aspen Technology Announces CFO Transition
Chantelle Breithaupt Stepping Down for a New Opportunity, Effective December 31, 2023
Christopher Stagno Appointed Interim CFO, Effective January 1, 2024
Reaffirms Full Year Fiscal 2024 Guidance
BEDFORD, Mass., October 19, 2023-- Aspen Technology, Inc. (AspenTech) (NASDAQ: AZPN), a global leader in industrial software, today announced that Chantelle Breithaupt has informed the Company that she will step down as Chief Financial Officer for another opportunity. Ms. Breithaupt will continue in her role through December 31, 2023. Christopher Stagno, who currently serves as SVP, Chief Accounting Officer, will assume the role of Interim CFO, effective January 1, 2024, should a permanent CFO not have been named.
The Company has commenced a search to identify its next CFO with the assistance of a leading executive search firm.
“Chantelle has been a remarkable leader throughout her tenure at AspenTech, playing a significant role in the successful completion of our transformative transaction with Emerson, which has positioned AspenTech well for the future,” said Antonio Pietri, President and Chief Executive Officer of AspenTech. “Chantelle has built an exceptionally talented finance team that is focused on executing our strategy and delivering long-term value for our shareholders. On behalf of the AspenTech team, I thank her for her invaluable contributions. We are fortunate to have Chantelle’s ongoing support through the end of the year and wish her all the best in the next chapter of her career.”
“AspenTech is an outstanding and innovative company, and it has been a privilege to serve as CFO for the past two and a half years,” said Ms. Breithaupt. “I am proud of the progress we’ve made against our strategic and financial goals, and I am confident in AspenTech’s strategy to continue delivering strong top- and bottom-line growth as it supports customer’s sustainability and energy transition objectives. I look forward to working alongside Antonio and our dedicated finance team over the next few months and to following AspenTech’s continued long-term success.”
Mr. Stagno is an experienced financial executive with deep knowledge of AspenTech’s business and over 25 years of leadership in finance, including at various software companies. Prior to joining AspenTech in 2020, he served as Treasurer at Cognex Corporation, a provider of machine vision products, software and sensors used in automated manufacturing. Before that, he served in various finance roles, including the Interim CFO role at Brightcove Inc., a provider of cloud-based services for video, and Unica, an enterprise marketing software company.
Mr. Pietri continued, “We are thankful to have a leader of Christopher’s caliber step into the Interim CFO role after Chantelle’s departure to give the Company the time it needs to complete its search for a permanent CFO.”
The Company today reaffirmed its outlook for the full year fiscal 2024, as provided on August 1, 2023. AspenTech will release financial results for its first quarter fiscal year 2024, ended September 30, 2023, after the U.S. financial markets close on Monday, November 6, 2023.
