Estimated reading time: 2 minutes

STMicroelectronics N.V. , a global semiconductor leader serving customers across the spectrum of electronics applications, reported U.S. GAAP financial results for the third quarter ended September 27, 2025.

ST reported third quarter net revenues of $3.19 billion, gross margin of 33.2%, operating income of $180 million, and net income of $237 million or $0.26 diluted earnings per share (non-U.S. GAAP1 operating income of $217 million, and non-U.S. GAAP1 net income of $267 million or $0.29 diluted earnings per share).

Jean-Marc Chery, ST President & CEO, commented:

• “Q3 net revenues came slightly above the mid-point of our business outlook range, with higher revenues in Personal Electronics, while Automotive and Industrial performed as anticipated, and CECP was broadly in line with expectations. Gross margin was slightly below the mid-point of our business outlook range mainly due to product mix within Automotive and Industrial.”
• “On a year-over-year basis, Q3 net revenues decreased 2.0%, non-U.S. GAAP1 operating margin decreased to 6.8% from 11.7% and non-U.S. GAAP1 net income decreased to $267 million from $351 million.”
• “In the third quarter, our book-to-bill ratio was above one, with Automotive above parity and Industrial at parity.”
• “Our fourth quarter business outlook, at the mid-point, is for net revenues of $3.28 billion, increasing sequentially by 2.9%, gross margin is expected to be about 35.0%; including about 290 basis points of unused capacity charges.”
• “The mid-point of this outlook translates into full year 2025 revenues of about $11.75 billion. This represents a 22.4% growth in the second half compared to the first half, confirming signs of market recovery. Gross margin is expected to be about 33.8%.”
• To optimize our investments in response to the current market conditions, we have reduced our Net Capex plan, now slightly below $2 billion for FY25.”
• “Our strategic priorities remain clear: accelerating innovation; executing our company-wide program to reshape our manufacturing footprint and resize our global cost base, which remains on schedule to deliver the targeted savings; and strengthening free cash flow generation.”

Net revenues totaled $3.19 billion, representing a year-over-year decrease of 2.0%. Year-over-year net sales to OEMs and Distribution decreased 5.1% and increased 7.6%, respectively. On a sequential basis, net revenues increased 15.2%, 60 basis points better than the mid-point of ST’s guidance.

Gross profit totaled $1.06 billion, representing a year-over-year decrease of 13.7%. Gross margin of 33.2%, 30 basis points below the mid-point of ST’s guidance, decreased 460 basis points year-over-year, mainly due to lower manufacturing efficiencies, negative currency effect, lower level of capacity reservation fees and, to a lesser extent, the combination of sale price and product mix.

Operating income decreased from $381 million in the year-ago quarter to $180 million. ST’s operating margin decreased 610 basis points on a year-over-year basis to 5.6% of net revenues, compared to 11.7% in the third quarter of 2024. Operating income included $37 million impairment, restructuring charges and other related phase-out costs for the quarter, reflecting impairment of assets and restructuring charges predominantly associated with the previously announced company-wide program to reshape our manufacturing footprint and resize our global cost base. Excluding these items, non-U.S. GAAP1 Operating income stood at $217 million in the third quarter.
