“Q3 net revenues increased 2.5% year-over-year. As expected, the revenue performance was driven mainly by continued growth in Automotive, partially offset by lower revenues in Personal Electronics.”

“On a year-over-year basis, gross margin remained stable at 47.6%, while, as expected, operating margin decreased to 28.0% from 29.4% and net income was stable at $1.09 billion.”

“First nine months net revenues increased 11.1% year-over-year, driven by growth in ADG and MDG Product Groups, partially offset by a decline of AMS Product Group. Operating margin was 27.6% and net income was $3.14 billion.”

Our fourth quarter business outlook, at the mid-point, is for net revenues of $4.30 billion, declining year-over-year and sequentially by about 3%; gross margin is expected to be about 46%.”

“The midpoint of this outlook translates into full year 2023 revenues of about $17.3 billion, representing 7.3% year-over-year growth and a gross margin of about 48.1%.”

Net revenues totaled $4.43 billion, representing a year-over-year increase of 2.5%. On a year-over-year basis, ADG and MDG revenues increased 29.6% and 2.8% respectively, while AMS decreased 28.3%. Year-over-year net sales to OEMs and Distribution increased 2.1% and 3.4%, respectively. On a sequential basis, net revenues increased 2.4%, 130 basis points better than the mid-point of ST’s guidance.

Gross profit totaled $2.11 billion, representing a year-over-year increase of 2.4%. Gross margin of 47.6% was stable year-over-year, as improved product mix was offset by higher manufacturing costs and unused capacity charges.

Operating income decreased 2.4% to $1.24 billion, compared to $1.27 billion in the year-ago quarter. ST’s operating margin decreased 140 basis points on a year-over-year basis to 28.0% of net revenues, compared to 29.4% in the 2022 third quarter
