Fiserv Inc. said its president, Dhivya Suryadevara, resigned, just weeks after she was promoted to the role following the departure of Chief Executive Officer Mike Lyons.

Suryadevara stepped down for “good reason” under her offer letter, according to a regulatory filing Tuesday. She will remain a non-executive officer through the end of July to help with the transition, the filing shows.

Andrew Gelb and Srini Krish were named interim leaders of the firm’s financial-solutions business, Fiserv spokesperson Stacy Davidson said in an emailed statement.

“The One Fiserv Action Plan and the strategy, priorities and key actions laid out at our investor day remain unchanged, and we continue to focus on delivering for clients through a client-first approach, innovation and platform modernization,” Davidson said in the statement.

Suryadevara’s departure is the latest shakeup in Fiserv’s management. The payments and banking software company has been going through a tumultuous time, with the stock falling nearly 70% in the last 12 months through Tuesday’s close. In June, Lyons, who had been working on a turnaround plan for the firm, left to take the top job at Truist Financial Corp.

Fiserv tapped Takis Georgakopoulos for the CEO role and gave Suryadevara the title of president, a move that some analysts viewed as a bid by Fiserv to retain talent.
