Nucor Corporation's fourth-quarter earnings report has prompted a downgrade from UBS as the company reported revenues of $7.69 billion, below the expected $7.9 billion, and earnings per share of $1.64, missing the $1.77 estimate. In response to these financial setbacks, Nucor's shares fell 2%, despite predicting a 5% increase in steel mill shipments for 2026. The company plans to continue returning value to shareholders, having repurchased approximately 0.7 million shares amid a challenging market landscape.
