Roth Capital analyst Craig Irwin argues that the post-earnings weakness in Cree (CREE) is "overdone" given that its earnings miss -- while difficult -- was smaller than peers. The analyst concedes, however, that the turnaround in Cree's Lighting Products segment is "taking longer than anyone would like," leading him to take a materially more conservative view of the unit. Irwin also updates his models to now include Cree's Wolfspeed. The proposed sale of Wolfspeed to Infineon (IFNNY) collapsed earlier this year, and while it remains attractive and "could see a sale to a third party," the analyst argues that a trade sale of the business "looks highly unlikely at this point." He lowered his price target on Cree shares to $27 from $33 but keeps a Buy rating on the stock.
