Urban Outfitters (URBN) – Urban Outfitters earned 89 cents per share for its latest quarter, 5 cents a share above estimates. Analysts had expected revenue to be slightly higher than actual.

J.M. Smucker (SJM) – The food producer reported quarterly earnings of $2.43 per share, beating the $2.05 a share consensus estimate. Smucker also exceeded expectations in revenue and raised its full-year outlook due to strong demand from its flagship brand, Jif, Folgers, and Milk-Bone. Smucker saw a 1.2% increase in premarket sales.

Xpeng (XPEV) – Xpeng jumped 3% in the premarket after the China-based electric vehicle maker reported a wider-than-expected quarterly loss, but also saw revenue come in well above estimates while issuing an upbeat current-quarter outlook.
