MILAN, Italy — Luxottica Group SpA named Stefano Grassi as chief financial officer, the latest executive appointment following two CEO resignations in as many months.

Grassi will join co-CEOs Adil Mehboob-Khan and Massimo Vian at the top of the world’s biggest eyeglass maker, the Milan- based company said in an e-mailed statement today. Luxottica reported net income of 162 million euros ($207 million) in the third quarter, topping the average analyst estimate of 157 million euros.

Luxottica is in the midst of boardroom upheaval following the resignation of Enrico Cavatorta after disagreements on corporate governance. Cavatorta’s departure came on the heels of Andrea Guerra’s resignation in September after a decade at the helm.
