Gilead Sciences reported adjusted earnings of $2.12 per share, slightly up from last year, but slashed its full-year forecast from $4.70-$5.20 to $3-$3.50 after a substantial $2.7 billion impairment charge related to Immunomedics. The company's revenue rose to $6.6 billion, driven by sales of its COVID-19 treatment, Veklury, yet Gilead missed earnings expectations by 54.9%. As a result, Gilead's shares have fallen, signaling investor concern amid strong drug performance.
