Becky Sheehan, who has served as chief financial officer of Cars.com since January 2017, has resigned her position to pursue a new opportunity with a private equity portfolio company.

The company appointed vice president of treasury and investor relations Jandy Tomy to serve as interim chief financial officer.

Sheehan’s resignation is effective Jan. 10.

CARS chief executive officer Alex Vetter said Sheehan built a strong finance organization in preparation of CARS becoming a standalone publicly traded company in 2017. Vetter said she has "continued to develop a deep bench of talented finance executives.”

“Becky was also instrumental in the transformation of CARS expanding from a traditional listings business to a full-service marketing and solutions provider that enables our dealer and OEM customers to compete in an increasingly digital market,” Vetter said in a news release.

He added, “We thank Becky for her dedication and wish her well in future endeavors."

Sheehan said she was proud of what CARS accomplished in what she described as a period of rapid transformation.

“The company is well positioned to deliver on its strategic plans and to continue its financial strength,” Sheehan said.

She continued, “I am grateful for the opportunity to have partnered with Alex and to have worked with so many talented colleagues.”

Tomy has been at CARS since March 2017, with more than 20 years of public company financial and accounting experience. The company has retained a search firm to fill the permanent chief financial officer position.
