Yahoo is bringing in a new chief financial officer as recently hired CEO Marissa Mayer prepares to share her vision for turning around the troubled internet company.

Software industry veteran Ken Goldman will replace Tim Morse as Yahoo’s CFO in a reshuffling announced Tuesday.

The change comes two months after Yahoo Inc. lured Ms. Mayer away from Google Inc. to become its CEO. She began sharing more details about her business strategy with Yahoo employees in series of meetings that began Tuesday.

The 63-year-old Goldman is leaving computer security software specialist Fortinet Inc. to become Yahoo’s CFO on Oct. 22.

Yahoo hired Mr. Morse as its CFO three years ago. He had focused on cutting costs to help the Sunnyvale, California, company boost its profits even as its revenue sank.
