Net revenue increased to approximately $3,868.0 million, an increase of 6% as compared to the prior fiscal year. This increase in revenue was primarily driven by our success in capturing a higher share of the increasing radio frequency and analog content per device as smartphone models continue to evolve, increases in applications for the IoT, and the expanding analog product portfolio supporting new vertical markets including aerospace, automotive, industrial, medical and military.
