“Supply chain disruptions are creating a lot of uncertainty for the holiday season,” Chief Financial Officer Steve Louden said in an interview. “We think these disruptions will be temporary, but they will persist through the holidays and into 2022, and it is hard to tell the exact path to normalcy.” He added that a broad-based shift toward streaming video remains intact.

The stock is down about 35% off a July peak after ending slightly higher in Wednesday’s regular session.
